MERGER PROPOSED — YOUR VOTE IS IMPORTANT

 

The boards of directors of Entegris, Inc. and Mykrolis Corporation have each unanimously approved a strategic merger of equals of the two companies. We believe that the combined company will be a global leader in materials integrity management for the microelectronics industry. The combined company, which will be headquartered in Chaska, Minnesota, immediately after the merger, will have approximately 2,700 full-time employees worldwide, excluding temporary workers. We believe that the merger will benefit the stockholders of both companies, and we ask for your support in voting for the merger proposals at our respective stockholders meetings.

 

Immediately prior to the merger, Entegris will reincorporate in the State of Delaware through a reincorporation merger with and into its wholly owned subsidiary, Eagle DE, Inc., which will be renamed Entegris, Inc. and is referred to herein as “Entegris Delaware.” Mykrolis will then merge with and into Entegris Delaware. In the merger, each share of Mykrolis common stock will be converted into the right to receive 1.39 shares of Entegris Delaware common stock and cash in lieu of fractional shares. After completion of the merger, the current stockholders of Entegris are expected to own approximately 56% of the combined company and the current stockholders of Mykrolis are expected to own approximately 44% of the combined company. The merger will be tax-free to Entegris stockholders and Mykrolis stockholders, except Mykrolis stockholders may recognize gain on any cash received in lieu of fractional shares of Entegris Delaware.

 

If the merger is completed, the combined company will be a Delaware corporation named “Entegris, Inc.” Entegris common stock is currently traded on The NASDAQ National Market under the symbol “ENTG,” and we intend to apply to have the combined company’s shares listed on The NASDAQ National Market at the time of the reincorporation merger. The listing of Entegris Delaware’s shares of common stock on The NASDAQ National Market is a condition to the closing of the merger. Upon completion of the merger, Mykrolis common stock, which is listed on the New York Stock Exchange under the symbol “MYK,” will be delisted.

 

We are asking stockholders of Entegris to consider and vote upon proposals to approve and adopt the merger agreement providing for the merger and the merger (including the issuance of Entegris Delaware common stock in connection with the merger); to reincorporate Entegris under the Delaware General Corporation Law and approve and adopt the agreement and plan of merger providing for the reincorporation; and to approve a classified board of directors for Entegris Delaware. Entegris’ special meeting will be held on [                    ], 2005, at [            ] a.m., local time, at [the Oak Ridge Conference Center, 1 Oak Ridge Drive, Chaska, Minnesota]. Entegris’ board of directors unanimously recommends that Entegris’ stockholders vote “FOR” each of the foregoing proposals.

 

We are asking stockholders of Mykrolis to consider and vote upon proposals to approve and adopt the merger agreement providing for the merger and the merger and to vote on the election of Mykrolis directors as described in the attached notice and joint proxy statement/prospectus. If the merger is completed, the terms of the Mykrolis directors, including those elected at the meeting, will expire upon such completion. Mykrolis’ special meeting in lieu of annual meeting will be held on [                    ], 2005, at 10:00 a.m., local time, at 129 Concord Road, Billerica, Massachusetts. Mykrolis’ board of directors unanimously recommends that Mykrolis’ stockholders vote “FOR” the merger and the adoption of the merger agreement, and “FOR” the election of the nominated directors.

 

We cannot complete the merger unless stockholders of both companies approve it and Entegris stockholders approve the proposed reincorporation of Entegris in Delaware. Approvals of the classified board of directors of Entegris Delaware and the election of Mykrolis directors are not conditions of the merger.

 

This joint proxy statement/prospectus provides you with detailed information about the stockholder meetings and the proposed merger and the other proposals to be voted on. We urge you to read this material, including the section describing certain risk factors beginning on page [    ], carefully and in its entirety.

 

We enthusiastically support this combination of our two outstanding companies and join with all the other members of our respective boards of directors in recommending that you vote “FOR” the proposals described herein.

QUESTIONS AND ANSWERS ABOUT THE MERGER

 

The following questions and answers briefly address some commonly asked questions about the merger, the stockholders meetings, the effect of the merger on the holders of common stock of Entegris and Mykrolis, and Entegris’ reincorporation from a Minnesota corporation to a Delaware corporation. They may not include all the information that is important to you. We urge you to read carefully this entire document, including the annexes and the other documents to which we have referred you. We have included page references in this summary to direct you to a more detailed description of each topic presented elsewhere in this joint proxy statement/prospectus.

 

Q: What will happen in the merger?

 

A: We are proposing to combine our companies in a “merger of equals” transaction. In the transaction, Entegris will effect a reincorporation from a Minnesota corporation to a Delaware corporation (the “reincorporation”). Mykrolis will then merge with and into Entegris Delaware, the corporation resulting from the reincorporation, and the combined company will be named Entegris, Inc. As a result of the merger of Mykrolis with and into Entegris Delaware, Mykrolis will cease to exist and Entegris Delaware will continue as a public company that holds and conducts the combined business of Mykrolis and Entegris. Mykrolis stockholders will have their shares of common stock converted into the right to receive newly issued shares of common stock of Entegris Delaware at an exchange ratio of 1.39 shares of common stock of Entegris Delaware for each share of common stock of Mykrolis (and cash in lieu of fractional shares). The shares of common stock of Entegris held by Entegris stockholders will be automatically converted without any action by stockholders into an equal number of shares of common stock of Entegris Delaware upon the completion of the reincorporation. See page [    ].

 

   The stockholders of Entegris immediately prior to the reincorporation merger will hold approximately 56% of the outstanding capital stock of the combined company immediately following the merger. The stockholders of Mykrolis immediately prior to the merger will hold approximately 44% of the outstanding capital stock of the combined company immediately following the merger. See page [    ].

 

   In the transaction, Entegris Delaware’s certificate of incorporation will be amended and restated as provided in Annex C-1 hereto, and its bylaws will be amended and restated as provided in Annex D hereto. Annex C-1 includes provisions relating to a so-called “classified board,” and the stockholders of Entegris will be asked to separately approve a proposal for the classified board. Approval of the classified board proposal, however, is not required to consummate the transaction. If the classified board proposal is not approved, Entegris Delaware’s certificate of incorporation will read as set forth in Annex C-2 and the bylaws set forth in Annex D will be revised by the Entegris Delaware board of directors to remove the classified board provisions and include provisions substantially similar to Article IX set forth in Annex C-2. See page [    ].

 

Q: Why are the companies proposing the merger?

 

A: The boards of directors of Entegris and Mykrolis believe, among other reasons, that the merger of Entegris and Mykrolis will create a combined company that is a global leader in materials integrity management for the microelectronics industry, with a stronger strategic and market position and an increased scale, scope and diversity of operations, product lines, served markets and customer base than could be achieved by either company on its own. See page [    ].

 

Q: What will a stockholder receive in the merger?

 

A:

In the merger, each share of Mykrolis common stock will be converted into the right to receive 1.39 shares of Entegris Delaware common stock.

closing sale price of Entegris common stock on The NASDAQ National Market on the trading day immediately preceding the date of the merger. See page [    ].

 

   Entegris stockholders will not receive consideration directly from the merger. Each share of Entegris common stock outstanding immediately prior to the reincorporation of Entegris from a Minnesota corporation to a Delaware corporation, however, will be automatically converted into one share of common stock of Entegris Delaware. Entegris Delaware will hold and conduct the combined businesses of Entegris and Mykrolis, and these shares of common stock of Entegris Delaware will remain outstanding after the merger. See page [    ].

 

Q: When is the Entegris special meeting?

 

A: The Entegris special meeting will be held on [                    ], 2005, at the location and time indicated on the cover of this joint proxy statement/prospectus. See page [    ].

 

Q: When is the Mykrolis special meeting in lieu of annual meeting?

 

A: The Mykrolis special meeting in lieu of annual meeting will be held on [                    ], 2005, at the location and time indicated on the cover of this joint proxy statement/prospectus. See page [    ].

 

Q: On what are Entegris stockholders being asked to vote?

 

A: Entegris’ board is asking Entegris stockholders to vote upon the following:

 

  1. A proposal to approve and adopt the merger agreement and the merger of Mykrolis with and into Entegris Delaware, including the issuance of new shares of Entegris Delaware to Mykrolis stockholders in connection with the merger (see page [    ]);

 

  2. A proposal to approve and adopt the reincorporation merger agreement and the reincorporation merger, including the proposed certificate of incorporation and bylaws of Entegris Delaware attached as Annex C-1 and Annex D, respectively, to this joint proxy statement/prospectus, provided that if proposal 3 set forth below is not approved, the certificate of incorporation of Entegris Delaware will read as set forth on Annex C-2 hereto and the bylaws of Entegris Delaware set forth on Annex D hereto will be revised by the Entegris Delaware board of directors to remove the classified board provisions and include provisions substantially similar to Article IX set forth in Annex C-2 hereto but will otherwise read as set forth on Annex D (see page [    ]);

 

  3. A proposal to approve a classified board for Entegris Delaware as provided in Article IX of the proposed certificate of incorporation of Entegris Delaware attached as Annex C-1 to this joint proxy statement/prospectus (see page [    ]); and

 

  4. A proposal to approve adjournments or postponements of the Entegris special meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the Entegris special meeting to approve the above proposals (see page [    ]).

 

   Neither the merger nor the reincorporation merger will occur unless both proposal 1 and proposal 2 are approved. Approval of proposals 3 and 4 is not a condition to either the merger or the reincorporation merger. If either proposal 1 or proposal 2 (or both) is not approved, then proposal 3 will be null and have no effect.

 

Q: Are the reincorporation and the merger each conditioned upon the other?

 

A:

The consummation of the reincorporation is conditioned on approval of the merger, and the consummation of the merger is conditioned on completion of the reincorporation. The reincorporation will not be effected unless all conditions to the merger have been satisfied or waived and Entegris Delaware and Mykrolis are

Table of Contents
 

prepared to consummate the merger immediately after the effective time of the reincorporation merger, and the merger will not occur if the reincorporation is not effected. See page [    ].

 

   The approval of the classified board provisions of Entegris Delaware’s certificate of incorporation is not required to consummate either the proposal relating to the merger or the proposal relating to the reincorporation. It is a condition to the classified board proposal, however, that proposals 1 and 2 be approved and that the reincorporation merger and the merger occur. See page [    ].

 

Q: What is Entegris’ proposed reincorporation from a Minnesota corporation to a Delaware corporation?

 

A: The proposed reincorporation involves changing Entegris’ state of incorporation from Minnesota to Delaware. The reincorporation will be effected by merging Entegris into a wholly owned subsidiary, named Eagle DE, Inc., which is incorporated in Delaware and which was formed for this purpose. Throughout this joint proxy statement/prospectus, the term “Entegris” refers to Entegris, Inc., the existing Minnesota corporation, and the term “Entegris Delaware” refers to Eagle DE, Inc., which is the proposed successor to Entegris in the proposed reincorporation.

 

   Upon the consummation of the reincorporation, Entegris will cease to exist as a corporate entity and Entegris Delaware will continue to operate Entegris’ business under the name Entegris, Inc. Each outstanding share of Entegris common stock will be automatically converted into one share of Entegris Delaware common stock at the effective time of the reincorporation. Each stock certificate representing issued and outstanding shares of Entegris common stock will represent the same number of shares of common stock of Entegris Delaware and need not be surrendered. Entegris expects to consummate the reincorporation immediately prior to the consummation of the merger. See page [    ].

 

Q: Why is Entegris reincorporating as a Delaware corporation?

 

A: During the negotiation of the merger agreement, Mykrolis asked Entegris to agree to reincorporate in Delaware and that the reincorporation be made a condition to completion of the merger. Mykrolis is a Delaware corporation and desires that the combined company be a Delaware corporation. As part of the negotiations, the Entegris board of directors agreed to Mykrolis’ request. As a result, the merger agreement provides that completion of the merger is conditioned on approval by Entegris stockholders of the reincorporation proposal and completion of the reincorporation.

 

   Many major corporations have chosen Delaware for their domicile or have subsequently reincorporated in Delaware. Because of Delaware’s significance as the state of incorporation for many major corporations, the Delaware judiciary has become particularly familiar with matters of corporate law, and a substantial body of court decisions has developed construing Delaware’s corporation laws. Consequently, Delaware corporate law has been, and is likely to continue to be, interpreted and explained in a number of significant court decisions, a circumstance which may provide greater predictability with respect to the combined company’s legal affairs.

 

Q: What is the proposal to approve a classified board for Entegris Delaware?

 

A:

The proposal to approve a classified board for Entegris Delaware would result in Entegris Delaware’s board of directors being divided into three classes of directors serving staggered terms. Staggering the terms of directors means that at the annual meeting in any given year, only a fraction (roughly one-third) of the directors are up for re-election. A classified board can increase the likelihood of continuity and stability in the policies formulated by the board of directors and increase a corporation’s ability to attract and retain

 

3


Table of Contents
 

desirable directors. A classified board may also prevent potential unsolicited acquirors from quickly obtaining control of the company in certain circumstances and thereby discourage attempts to acquire the company or remove management. The classification of directors would also have the effect of making it more difficult for stockholders to change the composition of Entegris Delaware’s board of directors in a relatively short period of time. See page [    ].

 

Q: On what are Mykrolis stockholders being asked to vote?

 

A: Mykrolis’ board is asking Mykrolis stockholders to vote upon the following:

 

  1. A proposal to approve and adopt the merger agreement and the merger (see page [    ]);

 

  2. A proposal to elect two Class II Directors to the Mykrolis board of directors with terms expiring at the Mykrolis 2008 annual meeting of stockholders or upon completion of the merger, if earlier (see page [    ]); and

 

  3. A proposal to approve adjournments or postponements of the Mykrolis special meeting in lieu of annual meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the Mykrolis special meeting in lieu of annual meeting to approve the above proposals (see page [    ]).

 

   Approval of proposals 2 and 3 is not a condition to the merger.

 

Q: Who is eligible to vote at the Entegris stockholder meeting?

 

A: Entegris stockholders are eligible to vote at the Entegris stockholder meeting if they were stockholders of record at the close of business on May 16, 2005. See page [    ].

A: Mykrolis stockholders are eligible to vote at the Mykrolis stockholder meeting if they were stockholders of record at the close of business on May 16, 2005. See page [    ]].

 

Q: What is the position of Entegris’ board of directors regarding the mergers?

 

A: Entegris’ board of directors has unanimously approved the merger agreement and the reincorporation merger agreement and the transactions contemplated by each of them and determined that the merger agreement and the reincorporation merger agreement and the transactions contemplated by the merger agreement, including the merger and the issuance of shares of Entegris Delaware common stock in the merger, and the reincorporation merger agreement are advisable, fair to and in the best interests of Entegris and its stockholders. Entegris’ board of directors unanimously recommends that Entegris stockholders vote “FOR” the proposals to approve and adopt the merger agreement and the merger and the reincorporation merger agreement and the reincorporation merger and the classified board proposal described above to be voted on at the special meeting of Entegris stockholders. See page [    ].

 

Q: What is the position of Mykrolis’ board of directors regarding the merger?

 

A: Mykrolis’ board of directors has unanimously approved the merger agreement and the transactions contemplated by the merger agreement and determined that the merger agreement and the merger are advisable, fair to and in the best interests of Mykrolis and its stockholders.

Table of Contents
Q: What vote is needed by Entegris stockholders to approve the proposals described above relating to the merger, the reincorporation merger and the classified board?

 

A: Each proposal requires the approval of the holders of a majority of the outstanding shares of Entegris common stock as of the record date, except that the proposal to approve the classified board requires the approval of the holders of at least 51% of the outstanding shares of Entegris common stock as of the record date. If an Entegris stockholder does not vote, it will have the same effect as a vote against each proposal. See page [    ].

 

Q: What vote is needed by Mykrolis stockholders to approve the merger agreement and the merger?

 

A: The proposal to approve and adopt the merger agreement and the merger requires the approval of the holders of a majority of the outstanding shares of Mykrolis common stock as of the record date. If a Mykrolis stockholder does not vote, it will have the same effect as a vote against the proposal to approve and adopt the merger agreement and the merger. See page [    ].

 

Q: How many votes does each share of Entegris common stock have?

 

A: Each share of Entegris common stock has one vote per share under the Entegris articles of incorporation and bylaws. See page [    ]. For a copy of Entegris’ articles of incorporation and bylaws, see “Where You Can Find More Information” beginning on page [    ]. Entegris’ articles of incorporation and bylaws are attached as Exhibits 3.3 and 3.4, respectively, to the Form S-4 registration statement of which this joint proxy statement/prospectus is a part.

 

Q: How many votes does each share of Mykrolis common stock have?

 

A: Each share of Mykrolis common stock has one vote per share under the Mykrolis certificate of incorporation. See page [    ]. For a copy of Mykrolis’ certificate of incorporation, see “Where You Can Find More Information” beginning on page [    ].

 

Q: How do Entegris’ directors and executive officers intend to vote?

 

A: Entegris’ directors and executive officers have indicated that they intend to vote their shares of Entegris common stock “FOR” all the proposals to be voted on by Entegris stockholders. At the close of business on May 16, 2005, the record date for the Entegris special meeting, directors and executive officers of Entegris and their affiliates were entitled to vote, or shared the right to vote, approximately [    ]% of the shares of Entegris common stock outstanding on that date. See page [    ].

 

Q: How do Mykrolis’ directors and executive officers intend to vote?

 

A: Mykrolis’ directors and executive officers have indicated that they intend to vote their shares of Mykrolis common stock FOR the proposal to approve and adopt the merger agreement and the merger. At the close of business on May 16, 2005, the record date for the Mykrolis special meeting in lieu of annual meeting, directors and executive officers of Mykrolis and their affiliates were entitled to vote less than 1% of the shares of Mykrolis common stock outstanding on that date. See page [    ].

 

Q: Do Entegris stockholders have dissenters’ appraisal rights?

 

A: No. Entegris stockholders do not have dissenters’ appraisal rights relating to the reincorporation merger under Minnesota law or, upon becoming stockholders of Entegris Delaware as a result of the reincorporation merger, relating to the merger under Delaware law. See page [    ].

 

Q: Do Mykrolis stockholders have dissenters’ appraisal rights?

 

A: No. Mykrolis stockholders do not have dissenters’ appraisal rights relating to the merger under Delaware law. See page [    ].

Table of Contents
Q: Will the rights of Entegris stockholders change as a result of the merger?

 

A: Yes. Entegris stockholders will become Entegris Delaware stockholders, and their rights will be governed by Delaware law and Entegris Delaware’s certificate of incorporation and bylaws. A description of those rights begins on page [    ].

 

   If the proposal relating to a classified board is approved by Entegris stockholders, the certificate of incorporation and bylaws of Entegris Delaware will read as set forth on Annex C-1 and Annex D hereto, respectively. Further, the merger agreement requires the board of directors of Entegris Delaware to adopt a stockholder rights plan comparable to the Mykrolis stockholder rights plan currently in effect. Both a classified board and a stockholder rights plan, together with other provisions of the proposed certificate of incorporation of Entegris Delaware, may have the effect of hindering or discouraging attempts to acquire the company or remove management even if some or a majority of Entegris Delaware’s stockholders believe this action to be in their best interest, including attempts that might result in the stockholders receiving a premium over the market price of their shares of common stock. See page [    ].

 

Q: Will the rights of Mykrolis stockholders change as a result of the merger?

 

A: The answer depends on how Entegris stockholders vote on Entegris proposal 3 (the classified board proposal). Mykrolis’ certificate of incorporation and bylaws currently contain classified board provisions. If Entegris stockholders approve proposals 1, 2 and 3, Entegris Delaware stockholders’ rights will be governed by the certificate of incorporation attached as Annex C-1 and the bylaws attached as Annex D to this joint proxy statement/prospectus, each of which is substantially similar to Mykrolis’ current certificate of incorporation and bylaws, except that the number of authorized shares of common stock will increase from 250,000,000 to 400,000,000 to reflect the combination of Entegris and Mykrolis. See “Comparison of Rights of Stockholders” beginning on page [    ] for a summary of the differences between the current Mykrolis certificate of incorporation and bylaws and the proposed Entegris Delaware certificate of incorporation and bylaws. If Entegris stockholders approve proposals 1 and 2 but not proposal 3, Entegris Delaware stockholders’ rights will be governed by the certificate of incorporation attached as Annex C-2 and the bylaws attached as Annex D to this joint proxy statement/prospectus (except that the bylaws attached as Annex D will be amended by the Entegris Delaware board of directors to remove the classified board provisions). See page [    ].

 

   To obtain a copy of Mykrolis’ current certificate of incorporation and bylaws, see “Where You Can Find More Information” on page [    ].

 

Q: Is Entegris common stock listed on The NASDAQ National Market?

 

A: Yes. Entegris common stock trades on The NASDAQ National Market under the symbol “ENTG.” The merger agreement requires Entegris to use its best efforts to cause shares of Entegris Delaware to trade on The NASDAQ National Market at the time of the reincorporation merger and the merger and to do so under the symbol “ENTG.” See page [    ]. The listing of Entegris Delaware’s common stock on The NASDAQ National Market is a condition to the obligation of each of Entegris and Mykrolis to complete the merger.

 

Q: Are there risks associated with the merger that I should consider in deciding how to vote?

 

A:

Yes. Among other things, the combined company may not achieve the expected benefits of the merger because of the risks and uncertainties discussed in the sections entitled “Risk Factors” beginning on page [    ] and “Cautionary Statement Concerning Forward-Looking Statements” beginning on page [    ]. Those risks include risks relating to the uncertainty that Entegris and Mykrolis will be able to integrate their businesses successfully, uncertainties as to whether the combined company will achieve synergies expected

 

6


Table of Contents
 

to result from the merger, and uncertainties relating to the performance of the combined company following the merger. See page [    ].

 

Q: Are any governmental approvals conditions to the closing of the merger?

 

A: Yes. The merger was subject to review by the U.S. Department of Justice and the U.S. Federal Trade Commission to determine whether it complies with the applicable antitrust laws. Under the provisions of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, the merger may not be consummated until the specified waiting period requirements of that Act have been satisfied. On April 21, 2005, the Federal Trade Commission granted early termination of the waiting period.

 

Q: When do you expect to complete the merger?

 

A: If the applicable proposals are approved at the stockholder meetings, we expect to complete the merger as soon as possible after the satisfaction of the conditions to the merger. We currently anticipate that the merger will be completed in [                    ] 2005. See page [    ].

 

Q: What are the material U.S. federal income tax consequences of the merger to Entegris and Mykrolis stockholders?

 

A: It is a condition to the merger that Entegris receive a legal opinion to the effect that the merger and the reincorporation will constitute “reorganizations” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. It is a condition to the merger that Mykrolis receive a legal opinion to the effect that the merger will constitute a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. Assuming that they so qualify, Entegris and Mykrolis stockholders generally will not recognize gain or loss for United States federal income tax purposes as a result of the merger and/or the reincorporation, except for gain or loss attributable to cash received by Mykrolis stockholders in lieu of fractional shares. See page [    ].

 

   The tax consequences to you will depend upon your own situation. You should consult your tax advisors for a full understanding of these tax consequences.

 

Q: What should I do now?

 

A: You should read this joint proxy statement/prospectus carefully and return your completed, signed and dated proxy card(s) by mail in the enclosed postage-paid envelope as soon as possible so that your shares will be represented and voted at your meeting. You may vote your shares by proxy by signing, dating and mailing the enclosed proxy card(s). In addition, stockholders may vote by proxy by calling the toll-free telephone number or by using the Internet as described in the instructions included with either the Entegris or Mykrolis stockholders’ proxy card(s). A number of banks and brokerage firms participate in a program that also permits stockholders whose shares are held in “street name” to direct their vote by the Internet or telephone. This option, if available, will be reflected in the voting instructions from the bank or brokerage firm that accompany this joint proxy statement/prospectus. If your shares are held in an account at a bank or brokerage firm that participates in such a program, you may direct the vote of these shares by the Internet or telephone by following the voting instructions enclosed with the proxy form from the bank or brokerage firm. See page [    ].

 

Q: If I am not going to attend my stockholder meeting, should I return my proxy card(s)?

 

A:

Yes. Returning your signed and dated proxy card(s) ensures that your shares will be represented and voted at your stockholder meeting, even if you are unable to or do not attend. Instead of returning their proxy card(s), Entegris and Mykrolis stockholders may vote by proxy by calling the toll-free telephone number or

Table of Contents
 

by using the Internet as described in the instructions included with the Entegris or Mykrolis stockholders’ proxy card(s), as the case may be. See page [    ].

 

Q: How will my proxy be voted?

 

A: If you complete, sign and date your proxy card(s), or, if available, grant your proxy by telephone or the Internet, your shares will be voted in accordance with your instructions. If you sign and date your proxy card(s) but do not indicate how you want to vote, your shares will be voted “FOR” the proposals at your meeting. See page [    ].

 

Q: What if my shares are held in “street name” by my broker?

 

A: Your broker will vote your shares with respect to the proposals at your meeting only if you provide written instructions to your broker on how to vote. You should instruct your broker using the instruction form and envelope provided by your broker. If you do not provide your broker with instructions, your broker will not be authorized to vote with respect to the applicable proposals at your meeting. If you hold your shares in your broker’s name and wish to vote in person at the meeting, you must contact your broker and request a document called a “broker’s proxy.” You must bring this broker’s proxy to your meeting in order to vote in person. See page [    ].

 

Q: What if Entegris stockholders abstain from voting or do not instruct their brokers to vote their shares?

 

A: If an Entegris stockholder does not vote or does not instruct a broker how to vote shares of Entegris common stock held in street name, i.e., “broker non-votes,” it will have the same effect as a vote against the proposals to approve and adopt the merger agreement and the merger and the reincorporation merger agreement and the reincorporation merger and to approve the classified board. See page [    ].

 

Q: What if Mykrolis stockholders abstain from voting or do not instruct their brokers to vote their shares?

 

A: If a Mykrolis stockholder does not vote or does not instruct a broker how to vote shares of Mykrolis common stock held in street name, i.e., “broker non-votes,” it will have the same effect as a vote against the proposal to approve and adopt the merger agreement and the merger but will not affect the election of directors. See page [    ].

 

Q: Can I change my vote after I mail my proxy card(s) or, if available, vote by telephone or the Internet?

 

A: Yes. If you are a record holder of Entegris common stock or Mykrolis common stock, you can change your vote by:

 

    sending a written notice to the corporate secretary of Entegris or Mykrolis, respectively, that is received prior to the vote at the meeting and states that you revoke your proxy; or

 

    signing and dating a new proxy card(s) and submitting it so that it is received prior to the vote at the meeting or, if available, granting a new proxy by telephone or on the Internet.

 

   Mykrolis stockholders may also revoke their proxy by attending the Mykrolis special meeting in lieu of annual meeting and voting in person. Entegris stockholders may also revoke their proxy by attending the Entegris special meeting and voting in person after having delivered to Entegris a written notice revoking their proxy.

 

   If your shares are held in street name by your broker, you will need to contact your broker to revoke your proxy. See page [    ].

Table of Contents
Q: Should stockholders send in their stock certificates now?

 

A: No. If the merger is completed, Mykrolis stockholders will be sent written instructions for sending in their stock certificates. Entegris stockholders will not need to send in their stock certificates, even if the merger is completed. See page [    ].

 

Q: What does it mean if I receive multiple proxy cards?

 

A: Your shares may be registered in more than one account, such as brokerage accounts and employee stock ownership plan accounts. It is important that you complete, sign, date and return each proxy card you receive, or, if available, vote by proxy using the telephone or the Internet as described in the instructions included with each proxy card you receive. See page [    ].

The Merger (beginning on page [    ])

 

General

 

On March 20, 2005, the boards of directors of each of Entegris and Mykrolis approved the combination of the two companies in a “merger of equals” transaction. In the transaction, Entegris will reincorporate from a Minnesota corporation to a Delaware corporation. Mykrolis will then merge with and into Entegris Delaware, the corporation resulting from the reincorporation, and the combined company will be renamed Entegris, Inc. As a result of the merger of Mykrolis with and into Entegris Delaware, Mykrolis will cease to exist and Entegris Delaware will continue as a public company that holds and conducts the combined businesses of Mykrolis and Entegris. The shares of Mykrolis common stock held by Mykrolis stockholders will be converted without any action by those stockholders into the right to receive newly issued shares of Entegris Delaware common stock upon completion of the merger. The shares of Entegris held by Entegris stockholders will be automatically converted without any action by those stockholders into shares of Entegris Delaware upon the completion of the reincorporation.

 

The stockholders of Entegris immediately prior to the reincorporation merger will hold approximately 56% of the outstanding capital stock of the combined company immediately following the merger. The stockholders of Mykrolis immediately prior to the merger will hold approximately 44% of the outstanding capital stock of the combined company immediately following the merger.

 

We encourage you to carefully read the merger agreement attached as Annex A to this joint proxy statement/prospectus and the reincorporation merger agreement attached as Annex B to this joint proxy statement/prospectus, which set forth the terms of the merger of Mykrolis with and into Entegris Delaware and the reincorporation of Entegris as a Delaware corporation.

 

Merger Consideration

 

In the merger, Mykrolis stockholders will have the right to receive 1.39 shares of Entegris Delaware common stock for each share of Mykrolis common stock. Instead of fractional shares of Entegris Delaware common stock, Mykrolis stockholders will receive cash in an amount equal to the fractional interest they would otherwise receive multiplied by the per-share closing sale price of Entegris common stock on The NASDAQ National Market on the trading day immediately preceding the date of the merger.

 

At the effective time of the merger, each outstanding option to purchase shares of Mykrolis common stock under Mykrolis’ stock option plans, whether vested or unvested, and each such Mykrolis stock option plan will be assumed by Entegris Delaware and thereafter each Mykrolis stock option will constitute an option to acquire shares of Entegris Delaware common stock, with appropriate adjustments in exercise prices and the number of shares subject to each option.

 

Entegris stockholders will not receive consideration directly from the merger. Each share of Entegris common stock outstanding immediately prior to the reincorporation of Entegris will be automatically converted into one share of common stock of Entegris Delaware, which will be the surviving company in the merger with Mykrolis and will ultimately be renamed Entegris, Inc.

 

At the effective time of the reincorporation merger, each outstanding option to purchase shares of Entegris common stock and each restricted stock unit that may be surrendered for Entegris common stock that has been granted under any employee stock option or compensation plan of, or other arrangement with, Entegris shall become an option or restricted stock unit, as the case may be, for the same number of shares of Entegris Delaware common stock.

On March 20, 2005, Goldman, Sachs & Co. rendered its oral opinion, subsequently confirmed by delivery of its written opinion dated March 21, 2005, to Entegris’ board of directors that, as of such date and based upon and subject to the factors and assumptions set forth therein, the exchange ratio of 1.39 shares of common stock of Entegris Delaware to be issued in exchange for each share of common stock of Mykrolis pursuant to the merger agreement is fair from a financial point of view to Entegris.

Share Ownership of Directors and Executive Officers of Entegris and Mykrolis (pages [    ] and [    ])

 

At the close of business on May 16, 2005, the record date for the Entegris special meeting, directors and executive officers of Entegris and their affiliates were entitled to vote, or shared the right to vote, approximately [    ]% of the shares of Entegris common stock outstanding on that date.

 

At the close of business on May 16, 2005, the record date for the Mykrolis special meeting in lieu of annual meeting, directors and executive officers of Mykrolis and their affiliates were entitled to vote approximately [    ]% of the shares of Mykrolis common stock outstanding on that date.

 

Interests of Entegris’ and Mykrolis’ Directors and Executive Officers in the Merger (beginning on page [    ])

 

In considering the recommendation of Entegris’ and Mykrolis’ board of directors with respect to the merger, stockholders of Entegris and Mykrolis should be aware that certain directors and executive officers of Entegris and Mykrolis may have interests in the merger that are different from, or in addition to, their interests as Entegris stockholders or Mykrolis stockholders generally.

 

For example, certain executive officers and directors of each of Entegris and Mykrolis will serve as executive officers or directors of the combined company following the merger, although no directors of Entegris will become executive officers of the combined company following the merger. Certain executive officers of Mykrolis have executive termination agreements with Mykrolis, some of which were amended in connection with the execution of the merger agreement, which guarantee such officers minimum levels of compensation following a triggering transaction, including the execution of the merger agreement, and which afford such officers certain payments and benefits in the event such officers are terminated or resign under certain circumstances, in each case within certain time periods following the execution of the merger agreement, subject to certain conditions. In addition, in connection with the execution of the merger agreement, Mykrolis entered into employment letter agreements with certain of its executives which specify material terms of the employment of such executives following the merger and will be assumed by Entegris Delaware by operation of law upon consummation of the merger. Such employment letter agreements contemplate that Entegris Delaware and such executives would enter into new change of control agreements upon consummation of the merger that would contain terms similar to the executive termination agreements referred to above and would also include a non-competition provision.

 

It is expected that Entegris Delaware will enter into change of control agreements with certain of Entegris’ current executives who will be employed by Entegris Delaware to replace such executives’ existing executive termination agreements with Entegris, some or all of the terms of which would be substantially the same as the new change of control agreements to be executed by Entegris Delaware and individuals who are currently Mykrolis officers upon consummation of the merger. It is also expected that upon consummation of the merger, these same current executives of Entegris will enter into employment letter agreements with Entegris Delaware, some or all of the terms of which would be substantially the same as the employment letter agreements between Mykrolis and current Mykrolis officers.

 

Each of Entegris’ and Mykrolis’ board of directors was aware of these officer and director interests during its respective deliberations on the merits of the merger and in deciding to recommend that you vote for the approval of the proposals presented at the stockholder meetings.

 

Board of Directors and Officers of the Surviving Corporation (beginning on page [    ])

 

Upon completion of the proposed merger, pursuant to the terms of the merger agreement, the board of directors of Entegris Delaware will consist of five directors designated by Entegris (initially expected to be James E. Dauwalter, Roger D. McDaniel, Gary F. Klingl, Paul L.H. Olson and Brian F. Sullivan) and five directors

designated by Mykrolis (initially expected to be Gideon Argov, Thomas O. Pyle, Michael P.C. Carns, Michael A. Bradley and Daniel W. Christman). The merger agreement also provides that the new board may approve an eleventh member after the effective time of the merger who is recommended by the chief executive officer and the chairman of the board of Entegris Delaware and nominated by the nominating and governance committee of the board of Entegris Delaware. Mykrolis and Entegris expect the eleventh director to be appointed shortly after the completion of the merger. As of the effective time of the merger, James E. Dauwalter will serve as the non-executive chairman of the Entegris Delaware board of directors. The board of directors of Entegris Delaware will have standing audit, nominating and governance and compensation committees, each comprised of an equal number of directors designated by Entegris and directors designated by Mykrolis.

 

If Entegris’ stockholders approve the classified board of directors of Entegris Delaware, as of the effective time of the merger, the board of directors of Entegris Delaware will be divided into three classes, the first class to be comprised of Gideon Argov, James E. Dauwalter and Brian F. Sullivan, the second class to be comprised of Michael A. Bradley, Daniel W. Christman, Gary F. Klingl and Thomas O. Pyle, and the third class to be comprised of Paul L.H. Olson, Roger D. McDaniel and Michael P.C. Carns. The term of the directors in the first class will expire at the first annual meeting of Entegris Delaware; the term of the directors in the second class will expire at the second annual meeting of Entegris Delaware; and the term of the directors in the third class will expire at the third annual meeting of Entegris Delaware. Following election at an annual meeting, a director’s term will be three years. If an eleventh director is appointed as expected, the nominating and governance committee of the Entegris Delaware board will recommend to the board of directors the class to which such eleventh director should be assigned. If Entegris’ stockholders do not approve a classified board, each of the aforementioned directors will stand for re-election at the first annual meeting of Entegris Delaware.

 

At the closing of the merger, Gideon Argov will be appointed chief executive officer of Entegris Delaware. The senior management team of Entegris Delaware at the closing of the merger will also include certain officers currently employed by each of Entegris and Mykrolis and a current consultant to Entegris.

 

Conditions to Completion of the Merger (page [    ])

 

As more fully described in this joint proxy statement/prospectus and the merger agreement, the completion of the merger depends on a number of conditions being satisfied or waived, including receipt of stockholder approvals, regulatory approvals and tax opinions.

 

Although we currently expect to complete the transaction in [                    ] 2005, we cannot be certain when, or if, the conditions to the transaction will be satisfied or waived, or that the transaction will be completed.

 

Termination of the Merger Agreement (beginning on page [    ])

 

We may mutually agree to terminate the merger agreement before completing the merger, even after the approval of the merger agreement and the merger by the Entegris stockholders and the Mykrolis stockholders. Mykrolis may also terminate the merger agreement if Entegris’ or Mykrolis’ stockholders do not approve the merger agreement and the merger or Entegris stockholders do not approve the reincorporation merger or if certain other conditions to Mykrolis’ obligation to effect the merger are not satisfied or waived. Entegris may also terminate the merger agreement if Mykrolis’ or Entegris’ stockholders do not approve the merger agreement and the merger or if certain other conditions to Entegris’ obligation to effect the merger are not satisfied or waived.

 

In addition, either of Entegris or Mykrolis may terminate the merger agreement, even after the requisite stockholder approvals have been received, if the merger has not been completed by December 31, 2005, or if the other party has materially breached certain obligations in the merger agreement concerning the solicitation of

Table of Contents

third party acquisition proposals or holding a stockholder meeting to seek stockholder approval for the merger, or if the board of directors of the other party has failed to make, has withdrawn, or has modified in a manner adverse to the terminating party, its recommendation to stockholders with respect to the merger and the related proposals.

 

Termination Fees and Expenses (beginning on page [    ])

 

Each of Entegris and Mykrolis has agreed to pay the other party a fee of $23.5 million in cash plus transaction expenses of the other party up to $1.5 million in any of the following circumstances:

 

    if the merger agreement is terminated because the paying party fails to recommend the merger or effects a change of recommendation or fails to comply in all material respects with the non-solicitation provisions in the merger agreement;

 

    if the merger agreement is terminated because the paying party’s board of directors or any committee thereof recommends or approves a third party acquisition proposal or fails to hold its stockholder meeting in accordance with the merger agreement; or

 

    if the merger agreement is terminated pursuant to certain provisions of the merger agreement, including the failure of the paying party’s stockholders to approve the merger, and (1) prior to the paying party’s stockholder meeting, a third party acquisition proposal relating to the paying party shall have been made and become known publicly or been made directly to the paying party’s stockholders generally and (2) within 12 months after such termination of the merger agreement, the paying party or any of its subsidiaries (a) enters into a definitive agreement with respect to any third party acquisition proposal and such third party acquisition proposal is subsequently consummated within or after such 12-month period, or (b) consummates any third party acquisition proposal.

 

No Solicitation (beginning on page [    ])

 

The merger agreement generally restricts the ability of each of Entegris and Mykrolis to solicit or engage in discussions or negotiations with a third party regarding a proposal to acquire significant stock or assets of, or to merge with, that party. However, if either Entegris or Mykrolis receives an unsolicited acquisition proposal from a third party that such party’s board of directors determines in good faith (after consultation with its outside counsel and its financial advisor) would reasonably be likely to result in a superior proposal and the party complies with specified procedures and satisfies specified conditions contained in the merger agreement, the party may furnish non-public information to that third party and engage in discussions or negotiations regarding an acquisition proposal with that third party.

 

Accounting Treatment (page [    ])

 

The merger will be accounted for as a business combination using the “purchase” method of accounting. Entegris will be the acquirer for financial accounting purposes.

 

Comparison of Rights of Stockholders (beginning on page [    ])

 

As a result of the merger, the holders of Mykrolis common stock and the holders of Entegris common stock will become holders of Entegris Delaware common stock. The rights of Mykrolis stockholders are currently governed by its certificate of incorporation and bylaws and the laws of Delaware, and the rights of Entegris stockholders are currently governed by its articles of incorporation and bylaws and the laws of Minnesota. The rights of Entegris Delaware’s stockholders will be governed by the laws of Delaware and Entegris Delaware’s certificate of incorporation and bylaws.

Regulatory Matters (beginning on page [    ])

 

The merger is subject to antitrust laws. Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, which we refer to throughout this joint proxy statement/prospectus as the HSR Act, the parties cannot complete the merger until they have notified and furnished information to the Federal Trade Commission and the Antitrust Division of the United States Department of Justice and the specified waiting period expires or is terminated. Entegris and Mykrolis filed the information required under the HSR Act on April 7, 2005. On April 21, 2005, the Federal Trade Commission granted early termination of the HSR Act waiting period.

 

Each state and other foreign country in which Entegris or Mykrolis has operations also may review the merger under state or foreign antitrust laws.

RISK FACTORS

 

In addition to the other information contained in or incorporated by reference into this joint proxy statement/prospectus, you should carefully consider the following risk factors in deciding whether to vote for, in the case of Entegris, approval of the merger agreement and the merger, the reincorporation merger agreement and the reincorporation merger, and the classified board provisions of the certificate of incorporation of Entegris Delaware, and, in the case of Mykrolis, approval of the merger agreement and the merger. Other risk factors with respect to Entegris can be found in Entegris’ Annual Report on Form 10-K for the fiscal year ended August 28, 2004, which is incorporated herein by reference. Other risk factors with respect to Mykrolis can be found in Mykrolis’ Annual Report on Form 10-K/A for the fiscal year ended December 31, 2004, which is incorporated herein by reference.

 

The market value of the Entegris Delaware common stock that Mykrolis stockholders will receive in the merger may be lower than expected.

 

In the merger, Mykrolis stockholders will have the right to receive 1.39 shares of Entegris Delaware common stock in exchange for each share of Mykrolis common stock held by them. This is a fixed exchange ratio. The merger agreement does not contain any provision to adjust this ratio for changes in the market price of Entegris common stock or Mykrolis common stock, and neither party is permitted to terminate the merger agreement solely because of such changes. The market value of Entegris Delaware common stock when the merger is completed may vary from the market value of Entegris common stock as of the date of this joint proxy statement/prospectus or as of the date of the special meeting meeting of Mykrolis stockholders in lieu of annual meeting and the special meeting of Entegris stockholders. This variation may result from ordinary trading fluctuations as well as changes in the business, operations or prospects of Entegris, general market and economic conditions, and other factors that may affect Entegris common stock differently from Mykrolis common stock. If the market value of Entegris common stock declines prior to the effective time of the merger, the market value of the stock issued to Mykrolis stockholders in the merger could be lower than expected. Note that the historical prices of Entegris’ and Mykrolis’ common stock included in this joint proxy statement/prospectus may not be indicative of their respective prices on the date the merger is effective. See “Financial Summary––Entegris’ Market Price Data and Dividends” and “Financial Summary––Mykrolis’ Market Price Data and Dividends.” You are urged to obtain recent market quotations for Entegris common stock and Mykrolis common stock. Future market prices of Entegris common stock, Entegris Delaware common stock and Mykrolis common stock cannot be guaranteed or predicted.

 

We may be unable to successfully integrate our operations and realize the full cost savings we anticipate.

 

The merger involves the integration of two companies that have previously operated independently. The difficulties of combining the operations of the companies include:

 

    the challenge of effecting integration while carrying on an ongoing business;

 

    the necessity of coordinating geographically separate organizations;

 

    retaining and integrating personnel with diverse business backgrounds and cultures;

 

    retaining existing customers and strategic partners of each company; and

 

    implementing and maintaining consistent standards, controls, procedures, policies and information systems.

 

The process of integrating operations could cause an interruption of, or loss of momentum in, the activities of one or more of the combined company’s businesses and the loss of key personnel. The diversion of management’s attention and any delays or difficulties encountered in connection with the merger and the integration of the two companies’ operations could have an adverse effect on the business, results of operations or financial condition of the combined company.

 

17


Table of Contents

Among the factors considered by the Entegris and Mykrolis boards of directors in connection with their respective approvals of the merger agreement and the merger were the benefits of the more diversified product line, the broader customer base and the enhanced technology capabilities, as well as the potential cost savings, that are expected to result from the merger. We cannot give you any assurance that these benefits will be realized within the time periods contemplated or at all.

 

Officers and directors of Entegris and Mykrolis may have interests in the merger that are different from, or in addition to, the interests of Entegris and Mykrolis stockholders.

 

Some of the directors and officers of Entegris and Mykrolis who recommend that stockholders vote in favor of the merger agreement and the merger or otherwise support the merger have, or are likely to have, employment, change in control or severance agreements or benefits arrangements that provide them with interests in the merger that differ from or are in addition to those of the stockholders. The receipt of compensation or other benefits in the merger, including change in control or severance benefits, the vesting of stock options, or the continuation of indemnification arrangements for current directors and officers of Entegris and Mykrolis following completion of the merger may influence officers and directors in supporting the merger or in making their recommendation that you vote in favor of the merger agreement. For more information about these interests, please see “Interests of Certain Persons in the Merger” beginning on page [    ].

 

Entegris and Mykrolis will incur substantial expenses whether or not the merger is completed.

 

Entegris and Mykrolis will incur substantial expenses related to the merger whether or not the merger is completed. These costs include fees for financial advisors, attorneys and accountants, filing fees and financial printing costs. Entegris currently expects to incur approximately $7.25 million in expenses, approximately $1.75 million of which are not contingent on the completion of the merger. Mykrolis currently expects to incur approximately $7.42 million in expenses, approximately $2.92 million of which are not contingent on the completion of the merger.

 

Failure to complete the merger could negatively affect Entegris’ and Mykrolis’ stock prices and each company’s future business and operations.

 

If the merger is not completed for any reason, the price of Entegris common stock and Mykrolis common stock may decline to the extent that the current market prices of Entegris common stock and Mykrolis common stock reflect a positive market assumption that the merger will be completed or to the extent that the failure to complete the merger results in a negative market reaction. In addition, if the merger is not completed, each company may be subject to a number of material risks, including:

 

    payment of a $23.5 million termination fee and expense reimbursement of up to $1.5 million under certain circumstances; and

 

    costs related to the merger, such as legal, accounting, financial advisor and printing fees and/or expenses, which must be paid even if the merger is not completed.

 

Moreover, if the merger agreement is terminated, either company may be unable to find a partner willing to engage in a similar transaction on terms as favorable as those set forth in the merger agreement, or at all. This could limit each company’s ability to pursue its strategic goals.

 

The market price of Entegris Delaware common stock may decline as a result of the merger.

 

The market price of Entegris Delaware common stock may decline as a result of the merger for a number of reasons, including if:

 

    the integration of Entegris and Mykrolis is not completed in a timely and efficient manner;

 

18


Table of Contents
    the combined company does not achieve the expected benefits of the merger as rapidly or to the extent anticipated by financial or industry analysts;

 

    the effect of the merger on the combined company’s financial results is not consistent with the expectations of financial or industry analysts; or

 

    significant stockholders of Entegris and Mykrolis decide to dispose of their shares of Entegris Delaware common stock following completion of the merger.

 

Uncertainty regarding the merger and the effects of the merger could adversely affect each company’s relationships with its customers, strategic partners or key employees.

 

In response to the announcement of the merger, customers and strategic partners of Entegris or Mykrolis may delay or defer decisions, or otherwise alter their relationships with each company, which could have a material adverse effect on the business of each company, whether or not the merger is completed. Moreover, current and prospective employees of Entegris and Mykrolis may experience uncertainty about their future roles with the combined company, which may adversely affect the ability of each company to attract and retain key management, technical and other personnel.

 

The deal-protection provisions of the merger agreement may deter alternative business combinations and could negatively impact the stock prices of Entegris and Mykrolis if the merger agreement is terminated in certain circumstances.

 

As a result of certain provisions of the merger agreement, it is possible that a third party who might be interested in pursuing a business combination proposal with Entegris or Mykrolis would be discouraged from doing so. In addition, restrictions in the merger agreement on solicitation prohibit Entegris and Mykrolis from soliciting any acquisition proposal or offer for a merger or business combination with any other party. Any such proposal might be advantageous to the stockholders of Entegris and Mykrolis when compared to the terms and conditions of the transaction described in this joint proxy statement/prospectus. In particular, the termination fee provision of the merger agreement may deter third parties from proposing alternative business combinations that might result in greater value to Entegris and Mykrolis stockholders than the merger. In addition, in the event the merger agreement is terminated by Entegris or Mykrolis in circumstances that obligate either party to pay a termination fee to the other party, including where either party terminates the merger agreement because the other party’s board of directors withdraws its support of the merger, Entegris’ or Mykrolis’ stock price may decline as a result of its payment of the termination fee. See “The Merger Agreement—No Solicitation; Termination Fees and Expenses.”

 

Entegris and Mykrolis may waive one or more of the conditions to the merger without resoliciting stockholder approval for the merger.

 

Each of the conditions to Entegris’ and Mykrolis’ obligations to complete the merger may be waived, in whole or in part, to the extent legally allowed, either unilaterally or by agreement of Entegris and Mykrolis. The boards of directors of Entegris and Mykrolis will evaluate the materiality of any such waiver to determine whether amendment of this joint proxy statement/prospectus and resolicitation of proxies is necessary. In the event that the board of directors of Entegris or Mykrolis determines any such waiver is not significant enough to require resolicitation of stockholders, it will have the discretion to complete the merger without seeking further stockholder approval.

On November 29, 2001, pursuant to the Mykrolis stockholder rights plan, the Mykrolis board of directors declared a dividend of one common stock purchase right for each share of Mykrolis common stock outstanding to stockholders of record on December 31, 2001, payable on January 4, 2002. Each right initially entitles the holder to purchase one share of Mykrolis common stock at a price of $130 (though the rights are not exercisable until after a triggering event) and, following a triggering event, allows the holder to purchase $260 in market value of shares of common stock of Mykrolis or, under certain circumstances, of an acquiring company, for $130. If the merger is not completed, any future payment of dividends on Mykrolis common stock will depend upon its financial condition, capital requirements and its earnings as well as other factors that Mykrolis’ board of directors deems relevant.

Summary Unaudited Pro Forma Condensed Combined Financial Data

 

We derived the following unaudited pro forma condensed combined financial data from Entegris’ audited consolidated financial statements for the year ended August 28, 2004, Mykrolis’ unaudited consolidated financial results for the twelve months ended July 3, 2004, Entegris’ unaudited consolidated financial statements for the six months ended February 26, 2005, and Mykrolis’ unaudited consolidated financial results for the six months ended December 31, 2004. The financial data have been prepared as if the proposed merger and the reincorporation had occurred on August 31, 2003 for the statements of operations and as of February 26, 2005 for the balance sheet data. The unaudited pro forma statements of operations and balance sheet data set forth below are not necessarily indicative of the results that actually would have been achieved had the proposed merger been consummated on August 31, 2003 for the statement of operations and as of February 26, 2005 for the balance sheet data, or that may be achieved in the future. The unaudited pro forma condensed combined financial data do not reflect any benefits from potential cost savings or revenue changes resulting from the proposed merger. You should read this information in conjunction with Entegris’ “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” Entegris’ consolidated financial statements and the notes thereto, Mykrolis’ “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” Mykrolis’ consolidated financial statements and notes thereto, and the “Unaudited Condensed Combined Pro Forma Financial Information” and the unaudited pro forma condensed combined financial statements and notes related thereto included in this joint proxy statement/prospectus or included in Entegris’ and Mykrolis’ Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q incorporated by reference into this joint proxy statement/prospectus.

 

The pro forma adjustments are based upon certain assumptions and preliminary available information that Entegris believes are reasonable under the circumstances. A final determination of fair values relating to the merger, which cannot be made prior to the completion of the merger, may differ materially from the preliminary estimates and will include management’s final valuation of the fair value of assets acquired and liabilities assumed. This final valuation will be based on the actual net tangible and identifiable intangible assets of Mykrolis that exist as of the date of the completion of the merger. The final valuation may change the allocations of the purchase price, which could affect the fair value assigned to the assets and liabilities and could result in a change to the unaudited pro forma condensed combined financial statements data. The pro forma adjustments are more fully described in the notes to the unaudited pro forma condensed combined financial statements found elsewhere in this joint proxy statement/prospectus.

COMPARATIVE PER SHARE INFORMATION

 

The following table presents historical per share information and book value per common share data separately for Entegris and Mykrolis on a historical basis, and Entegris and Mykrolis on an unaudited pro forma combined basis per share of Entegris common stock and on an unaudited pro forma combined basis per Mykrolis equivalent share. The unaudited pro forma earnings per share data reflect the assumption that the merger was effective as of August 31, 2003. The unaudited pro forma book value per share data assumes the merger was effective February 26, 2005. The unaudited pro forma per share data gives effect to the proposed merger as a purchase by Entegris under generally accepted accounting principles in the United States.

 

You should read the information below together with the historical financial statements and related notes of Entegris and Mykrolis contained in each company’s periodic filings with the Securities and Exchange Commission and incorporated into this joint proxy statement/prospectus by reference. See “Where You Can Find More Information” beginning on page [    ]. The unaudited pro forma combined per share data below is presented for illustrative purposes only. The companies may have performed differently had they actually been combined during the periods presented below. You should not rely on this information as being indicative of the historical results that would have been achieved had the companies always been combined or the future results that the combined company will experience after the proposed merger.

THE ENTEGRIS SPECIAL MEETING

 

General

 

This joint proxy statement/prospectus is first being mailed by Entegris to the holders of Entegris common stock on or about [                    ], 2005, and is accompanied by the notice of the Entegris special meeting and a form of proxy that is solicited by the board of directors of Entegris for use at the special meeting of Entegris stockholders, to be held on [                    ], [                    ], 2005, at [    ] a.m., local time, at [the Oak Ridge Conference Center, 1 Oak Ridge Drive, Chaska, Minnesota], and at any adjournments or postponements of the meeting.

 

Matters to Be Considered

 

The purpose of the meeting is:

 

  1. To consider and vote upon a proposal to approve and adopt the Agreement and Plan of Merger (the “merger agreement”), dated as of March 21, 2005, by and among Entegris, Inc., a Minnesota corporation, Eagle DE, Inc., a Delaware corporation and a wholly owned subsidiary of Entegris (referred to as “Entegris Delaware”), and Mykrolis Corporation, a Delaware corporation, including the merger of Mykrolis with and into Entegris Delaware (immediately following the reincorporation merger described in proposal 2 below) as contemplated thereby and the issuance of new shares of common stock of Entegris Delaware to the stockholders of Mykrolis in the merger. In the merger, each outstanding share of Mykrolis common stock will be automatically converted into the right to receive 1.39 shares of Entegris Delaware common stock;

 

  2. To consider and vote upon a proposal to approve and adopt the Agreement and Plan of Merger (the “reincorporation merger agreement”) dated as of March 21, 2005, by and between Entegris and Entegris Delaware and the reincorporation merger contemplated thereby (the “reincorporation merger”), whereby Entegris would reincorporate from a Minnesota corporation to a Delaware corporation, including approval of the proposed certificate of incorporation and bylaws of Entegris Delaware attached as Annex C-1 and Annex D, respectively, to this joint proxy statement/prospectus, provided that if proposal 3 set forth below is not approved, the certificate of incorporation of Entegris Delaware will read as set forth on Annex C-2 hereto and the bylaws of Entegris Delaware set forth on Annex D hereto will be revised by the board of directors of Entegris Delaware to remove the classified board provisions and include provisions substantially similar to Article IX set forth in Annex C-2 hereto but will otherwise read as set forth on Annex D. In the reincorporation merger, each outstanding share of Entegris common stock will be automatically converted into one share of Entegris Delaware common stock and the name of Entegris Delaware will be changed to Entegris, Inc.;

 

  3. To consider and vote upon a proposal to approve a classified board for Entegris Delaware as provided in Article IX of the proposed certificate of incorporation of Entegris Delaware set forth in Annex C-1 hereto; and

 

  4. To consider and vote upon a proposal to approve adjournments or postponements of the Entegris special meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the Entegris special meeting to approve the above proposals.

 

The Entegris board of directors unanimously recommends that Entegris stockholders vote “FOR” each of the proposals. Neither the merger nor the reincorporation merger will occur unless both proposal 1 and proposal 2 are approved. Approval of proposals 3 and 4, however, is not a condition to either the merger or the reincorporation merger. If either proposal 1 or proposal 2 (or both) is not approved, then proposal 3 will be null and have no effect.

Proxies

 

The Entegris board of directors is soliciting your proxy to give you the opportunity to vote at the Entegris special meeting. When you deliver a valid proxy, the shares represented by that proxy will be voted in accordance with your instructions.

 

Please complete, sign, date and return the accompanying proxy card promptly in the enclosed addressed envelope, even if you plan to attend the special meeting. Postage need not be affixed to the envelope if mailed in the United States. The immediate return of your proxy card will be of great assistance in preparing for the special meeting and is, therefore, urgently requested. If you attend the special meeting, revoke your proxy and vote in person, your proxy card will not be used. Instead of submitting your proxy vote with the accompanying paper proxy card, you may grant your proxy via the Internet or by telephone by following the procedures set forth on the proxy card. Your telephone or Internet proxy authorizes the named proxies to vote your shares in the same manner as if you marked, signed and returned your proxy card. If you grant your proxy by Internet or by telephone, you do NOT need to mail back your proxy card. To view the proxy materials online, go to www.entegris.com. If you plan to attend the special meeting to be held on [                    ], 2005, at [    ] a.m., local time, at [the Oak Ridge Conference Center, 1 Oak Ridge Drive, Chaska, Minnesota], please be sure to check the box on your proxy card indicating your desire to attend, or indicate your desire to attend through Entegris’ telephone or Internet voting procedures.

 

If your shares are not registered in your own name and you plan to attend the special meeting and vote your shares in person, you should contact your broker or agent in whose name your shares are registered to obtain a broker’s proxy and bring it to the special meeting in order to vote.

 

A stockholder giving a proxy may revoke it at any time before it is voted by executing and delivering to Entegris another proxy bearing a later date and submitting it so that it is received prior to the vote at the meeting or, if available, granting a new proxy by telephone or on the Internet, by delivering a written notice prior to the vote at the meeting to the secretary of Entegris stating that the proxy is revoked, or by voting in person at the special meeting after having delivered to Entegris a written notice revoking your proxy. Any properly executed proxy returned to Entegris will be voted at the special meeting in accordance with the instructions indicated thereon. If no instructions are indicated on the proxy, the proxy will be voted “FOR” the approval of proposals 1, 2, 3 and 4. The proxies will be entitled to vote in their discretion on any other matters that may properly come before the meeting.

 

Solicitation of Proxies

 

Each of Entegris and Mykrolis will bear its own cost of soliciting proxies from its stockholders, except that each of Mykrolis and Entegris has agreed to pay one-half of the costs of printing, filing and mailing this joint proxy statement/prospectus and related proxy and proxy materials.

 

In addition to solicitations by mail, Entegris’ directors, officers and regular employees, without additional remuneration, may solicit proxies by telephone, personal interviews and the Internet. Brokers, custodians and fiduciaries will be requested to forward proxy soliciting material to the owners of stock held in their names, and Entegris will reimburse them for their reasonable out-of-pocket expenses incurred in connection with the distribution of proxy materials. Entegris and Mykrolis have also made arrangements with MacKenzie Partners, Inc. to assist them in soliciting proxies, and have each agreed to pay one-half of MacKenzie Partners’ fee, currently estimated to be approximately $12,500 in the aggregate, plus expenses for those services.

 

Record Date

 

The record date for the determination of stockholders entitled to notice of and to vote at the Entegris special meeting was May 16, 2005. On the record date, there were [                    ] shares of Entegris common stock, $.01 par value per share (Entegris’ only voting securities), outstanding and entitled to vote, which were held by approximately [                    ] holders of record. Each share of Entegris common stock is entitled to one vote.

Quorum

 

Under Entegris’ bylaws, the holders of a majority of the outstanding shares of Entegris common stock entitled to vote at the meeting will constitute a quorum for the purpose of taking any action other than adjourning the meeting. Shares of common stock represented in person or by proxy (including shares which abstain or do not vote with respect to one or more of the matters presented for stockholder approval) will be counted for purposes of determining whether a quorum is present. Brokers who hold shares of Entegris common stock in nominee or “street name” for customers who are the beneficial owners of those shares are prohibited from giving a proxy to vote shares held for those customers on proposals 1, 2 and 3 at the meeting without specific instructions from those customers. These “broker non-votes” will, however, be counted as present for purposes of determining whether a quorum exists.

 

Vote Required

 

The affirmative vote of the holders of a majority of the outstanding shares of Entegris common stock as of the record date is required to approve proposals 1 and 2. The affirmative vote of the holders of at least 51% of the outstanding shares of Entegris common stock as of the record date is required to approve proposal 3. The affirmative vote of the holders of the greater of (1) a majority of the shares of common stock present in person or by proxy at the meeting and entitled to vote or (2) a majority of the minimum number of shares entitled to vote that would constitute a quorum for the transaction of business at the meeting is required for approval of proposal 4.

 

Neither the merger nor the reincorporation merger will occur unless both proposal 1 and proposal 2 are approved. Approval of proposals 3 and 4, however, is not a condition to either the merger or the reincorporation merger. If Entegris’ stockholders do not approve both proposals 1 and 2, then proposal 3 will be null and have no effect.

 

Because approval of each of the merger, the reincorporation merger and the classified board proposal requires the affirmative vote of at least a majority (or 51%, in the case of the classified board proposal) of the outstanding shares of common stock of Entegris as of the record date, abstentions, failures to grant a proxy or vote at the meeting and broker non-votes will have the effect of a vote against proposals 1, 2 and 3. Accordingly, the Entegris board urges Entegris stockholders to complete, date and sign the accompanying proxy and return it promptly in the enclosed, postage-paid envelope or to authorize the individuals named on your proxy card to vote your shares by telephone or on the Internet.

 

Share Ownership as of the Record Date

 

As of the Entegris record date, directors and executive officers of Entegris beneficially owned and were entitled to vote, or shared the right to vote, [                    ] shares of Entegris common stock. Those shares represent approximately [    ]% of the outstanding shares of Entegris common stock entitled to vote at the Entegris special meeting.

 

Additional information with respect to beneficial ownership of Entegris common stock by directors and executive officers of Entegris is incorporated by reference to Entegris’ proxy statement filed with the Securities and Exchange Commission on December 15, 2004. See “Where You Can Find More Information.”

 

Treatment of Abstentions and Broker Non-Votes

 

If you submit a proxy that indicates an abstention from voting, your shares will be counted as present for purposes of determining the existence of a quorum and they will have the effect of votes against each of proposals 1, 2, 3 and 4.

 

If you hold your shares in “street name,” your bank or broker cannot vote your shares of Entegris common stock without specific instructions from you. If you do not provide instructions with your proxy, your bank or

 

30


Table of Contents

broker may deliver a proxy card expressly indicating that it is NOT voting your shares; this indication that a bank or broker is not voting your shares is referred to as a “broker non-vote.” Broker non-votes will be counted for the purpose of determining the existence of a quorum, and they will have the effect of votes against each of proposals 1, 2 and 3.

 

No Other Business; Adjournments

 

Under Minnesota law and Entegris’ bylaws, the business to be conducted at the meeting will be limited to considering and voting on the proposals.

 

Adjournments may be made for the purpose of, among other things, soliciting additional proxies. Any adjournment of up to 120 days in the aggregate may be made from time to time by the chairman or otherwise with the approval of the holders of shares representing the greater of (a) a majority of the votes present in person or by proxy at the time of the vote, or (b) a majority of the minimum number of votes that would constitute a quorum, without further notice other than by an announcement made at the original meeting of the date, time and place of the adjourned meeting.

Solicitation of Proxies

 

Each of Entegris and Mykrolis will bear its own cost of soliciting proxies from its stockholders, except that each of Mykrolis and Entegris has agreed to pay one-half of the costs of printing, filing and mailing this joint proxy statement/prospectus and related proxy and proxy materials.

 

In addition to solicitations by mail, Mykrolis’ directors, officers and regular employees, without additional remuneration, may solicit proxies by telephone, personal interviews and the Internet. Brokers, custodians and fiduciaries will be requested to forward proxy soliciting material to the owners of stock held in their names, and Mykrolis will reimburse them for their reasonable out-of-pocket expenses incurred in connection with the distribution of proxy materials.

Vote Required

 

The affirmative vote of the holders of a majority of the outstanding shares of common stock of Mykrolis as of the record date is required for the approval and adoption of the merger agreement and approval of the merger. If a quorum is present, the two nominees for election as directors of Mykrolis who receive the highest number of votes at the special meeting in lieu of annual meeting will be elected.

 

Because approval of the merger requires the affirmative vote of at least a majority of the outstanding shares of common stock of Mykrolis as of the record date, abstentions, failures to grant a proxy or vote at the meeting and broker non-votes will have the effect of a vote against proposal 1.

Treatment of Abstentions and Broker Non-Votes

 

If you submit a proxy that indicates an abstention from voting, your shares will be counted as present for purposes of determining the existence of a quorum and they will have the effect of votes against proposals 1 and 3 but will not affect proposal 2.

 

If you hold your shares in “street name,” your bank or broker cannot vote your shares of Mykrolis common stock without specific instructions from you.

No Other Business; Adjournments

 

Under Delaware law and Mykrolis’ bylaws, the business to be conducted at the meeting will be limited to considering and voting on the proposals.

 

Adjournments may be made for the purpose of, among other things, soliciting additional proxies. Any meeting of stockholders may be adjourned to any other time and to any other place at which a meeting of stockholders may be held under Mykrolis bylaws by a majority of the stockholders present or represented at the meeting and entitled to vote, although less than a quorum, or, if no stockholder is present, by any officer entitled to preside at or to act as secretary of such meeting.

THE MERGER

 

Background of the Merger

 

Mykrolis and Entegris have been familiar with each other’s businesses for many years, and Entegris has been a supplier of molded plastic components to Mykrolis (and prior to Mykrolis’ spin-off from Millipore Corporation in 2001, to Millipore) for over ten years. As a result of this commercial relationship, representatives of Mykrolis and Entegris have historically met and consulted with each other concerning matters relating to their supply relationship as well as their respective views as to trends in the materials integrity management and semiconductor industries.

 

Each of Mykrolis and Entegris continually evaluates strategic opportunities as a part of their ongoing evaluation of the market and opportunities to strengthen their respective businesses in light of the changing competitive environment. Both Mykrolis and Entegris senior management regularly review, evaluate and discuss various strategic opportunities. While both companies believe they have positive future prospects on a stand-alone basis, the management of Entegris, in recent years, has had conversations with or regarding a number of other companies about a range of options to improve its competitive position, including acquisitions, mergers of equals or other significant transactions, and for the past year Mykrolis has been looking for acquisition and merger opportunities that would permit it to rapidly expand its critical mass and increase the size and scope of its product offering to microelectronics (including semiconductor) industry customers.

 

In late June 2004, James Dauwalter, Entegris’ chief executive officer, informed the Entegris board of directors that Mykrolis had recently announced that C. William Zadel, the then chairman and chief executive officer of Mykrolis, intended to retire and that Mykrolis would begin an internal and external search for a new chief executive officer. Mr. Dauwalter advised the board of directors that he was attempting to arrange a meeting with Mr. Zadel to discuss a possible transaction between Entegris and Mykrolis.

 

On June 29, 2004, at a regularly scheduled meeting of the Entegris board of directors, Greg Graves, Entegris’ chief business development officer, gave a presentation concerning Mykrolis and discussed the potential benefits to Entegris and its stockholders of a combination between Entegris and Mykrolis. The Entegris board of directors indicated its support of initiatives designed to enhance stockholder value and authorized Entegris management to continue to pursue preliminary discussions with Mykrolis regarding a possible business combination.

 

In mid-July 2004, Mr. Dauwalter and Mr. Zadel both attended the Semiconductor Equipment and Materials Institute’s “SEMICON West” conference in San Francisco. While there, Mr. Dauwalter and Mr. Zadel met over dinner on July 13 and had preliminary discussions about the merits of a possible business combination between Entegris and Mykrolis. A representative of Citigroup Global Markets Inc. arranged and attended the dinner meeting. At the time of the meeting, Citigroup had not been engaged to represent either party in connection with a possible strategic transaction involving Entegris and Mykrolis. Mr. Zadel and Mr. Dauwalter discussed what each company could contribute to a combined company and the potential to enhance stockholder value through such a combination. Mr. Zadel agreed to discuss the idea of a possible business combination between Entegris and Mykrolis with Mykrolis management and with the Mykrolis board of directors in the next few months. Mr. Zadel and Mr. Dauwalter also agreed to further consider individually the possibility of such a combination.

 

During August and September 2004, Mr. Dauwalter talked with Mr. Zadel a number of times by telephone to follow up on their July 13 meeting and to try to gauge the level of Mykrolis’ interest in a possible transaction with Entegris. In one conversation, Mr. Zadel informed Mr. Dauwalter that Mykrolis had a regularly scheduled meeting of its board of directors on October 27, 2004, and that Mr. Zadel intended to discuss a possible combination with Entegris at that meeting.

 

In October 2004, Entegris retained Goldman, Sachs & Co. as its financial advisor. Entegris and Goldman Sachs agreed that Goldman Sachs would assist Entegris in evaluating three alternative possible business

 

35


Table of Contents

combinations, including the one between Entegris and Mykrolis that Mr. Dauwalter and Mr. Zadel were discussing, as well as other possible strategic alternatives.

 

On October 12, 2004, at a regularly scheduled meeting of the Entegris board of directors, representatives of Goldman Sachs made a presentation on industry trends and discussed its preliminary analysis of various strategic alternatives being explored by Entegris, one of which was the possible combination with Mykrolis. Entegris management, after consultation with Goldman Sachs, continued to support exploring the possible transaction with Mykrolis and concluded that it represented the most attractive strategic alternative for Entegris and its stockholders. The Entegris board of directors indicated its support for Entegris management’s efforts to enhance stockholder value and encouraged them to continue to explore the possibility of a transaction that would achieve this objective.

 

On October 19, 2004, Mr. Dauwalter sent a letter to Mr. Zadel stating that he wanted to formally express Entegris’ interest in moving forward with more specific discussions regarding a potential combination between Entegris and Mykrolis. Mr. Dauwalter noted that Entegris’ board of directors was in unanimous support of engaging in further discussions with Mykrolis and informed Mr. Zadel that Entegris had engaged Goldman Sachs as its financial advisor. Mr. Dauwalter stated that Entegris believed that a combination could create significant value for both companies’ stockholders and customers and significant growth opportunities for employees. The letter proposed a merger, with both companies contributing to the combined company’s management team and board of directors. Mr. Dauwalter indicated that Entegris was prepared to enter into discussions and commence a due diligence process immediately. The letter concluded by asking Mr. Zadel to discuss the possible transaction with the Mykrolis board of directors at its October 27 meeting.

 

On October 27, 2004, at a regularly scheduled meeting of the Mykrolis board of directors, Mr. Zadel outlined for the board four potential strategic transactions, including a review of each company’s business, product lines, mission, vision, strategic intent, core competencies, competition, manufacturing capabilities and strategic benefits and synergies from a potential combination. Entegris was among the companies included in this presentation. During this meeting, the directors and management discussed these potential transactions in the context of which would provide the greatest maximization of value for Mykrolis stockholders. At the conclusion of these discussions, however, the Mykrolis board of directors determined that, since the board was in the process of selecting a new chief executive officer to succeed Mr. Zadel upon his upcoming retirement, it was not appropriate to proceed with any of the initiatives until the CEO succession issue was resolved.

 

On October 28, 2004, Mr. Zadel sent an e-mail to Mr. Dauwalter in which he advised Mr. Dauwalter that the Mykrolis board of directors had met on October 27 and reviewed in detail Entegris’ suggestion to work toward a merger of equals. Mr. Zadel wrote that the Mykrolis board of directors had decided to continue with their efforts to select Mr. Zadel’s successor and to move forward as an independent company. Mr. Zadel offered to discuss the matter further with Mr. Dauwalter by telephone if Mr. Dauwalter wanted more details.

 

Following Mr. Zadel’s e-mail, no communications between Entegris and Mykrolis regarding the potential combination occurred for several weeks. On November 22, 2004, Mykrolis announced that Mr. Zadel had resigned as chief executive officer of Mykrolis in order to implement his previously announced retirement plans and that Mykrolis had selected Gideon Argov to succeed Mr. Zadel as Mykrolis’ chief executive officer. Shortly after this announcement, Mr. Graves, Entegris’ chief business development officer, contacted Peter S. Kirlin, the vice president of business development for Mykrolis, to request a meeting with Mr. Kirlin in order to discuss the reaction of the Mykrolis board of directors to Mr. Dauwalter’s October 19 letter to Mr. Zadel as expressed in Mr. Zadel’s October 28 e-mail and to determine whether Mykrolis would have renewed interest in exploring a business combination.

 

On December 14, 2004, Mr. Graves and Mr. Kirlin met in Boston and discussed industry trends and the potential benefits of a business combination between Entegris and Mykrolis. Mr. Kirlin agreed that a combination between the two companies should be seriously explored given the potential benefits. Mr. Graves

 

36


Table of Contents

asked if Mr. Kirlin would be willing to try to arrange a meeting among the two of them and the chief executive officers of each company to discuss a possible transaction. Mr. Kirlin agreed to talk to Mr. Argov to arrange such a meeting.

 

Following the December 14 meeting, Mykrolis commenced a general analysis of a possible business combination with Entegris using publicly available information about Entegris and reviewed certain strategic, financial and other aspects of a possible business combination with Entegris. In addition, in furtherance of Mykrolis’ ongoing evaluation of strategic transactions that would permit it to rapidly increase the size and scope of its product offering to semiconductor industry customers, Mykrolis commenced discussions with another significant industry participant regarding a possible strategic transaction. On December 16, 2004, Mykrolis entered into non-disclosure agreements with this industry participant and on December 22, 2004, representatives of Mykrolis met with representatives of the industry participant to further discuss its interest in pursuing a strategic transaction and to discuss the rationale for such a strategic transaction.

 

On January 11, 2005, Messrs. Dauwalter and Graves met with Messrs. Argov and Kirlin for dinner in Boston. The discussions first focused on the executives’ views on the state of the semiconductor industry generally and the subsystems, components and materials segment of the semiconductor industry. This led to a discussion of the rationale for a possible business combination transaction between Mykrolis and Entegris, including the strategic ramifications and potential financial benefits of such a transaction. The participants in this meeting all agreed that a business combination between the two companies made strategic sense, among other reasons, because of the companies’ complementary technologies, products and customer base and the enhanced scale a combination would provide. They also reached an understanding that a merger of equals, and not an acquisition by one company of the other, was the appropriate form for a transaction. The meeting concluded with the executives agreeing to exchange strategic plans and to try to arrange a meeting among a broader group of executives from both companies.

 

Shortly after this January 11 meeting, Peter W. Walcott, the general counsel of Mykrolis, prepared drafts of non-disclosure agreements to be executed by each party prior to exchanging any non-public information. After exchanges of comments on the draft agreements, each of Mykrolis and Entegris executed a non-disclosure agreement as of January 21, 2005.

 

On January 18, 2005, Entegris held a regularly scheduled board meeting. Mr. Dauwalter and Mr. Graves updated the board on their contacts and activities with respect to Mykrolis. The Entegris board of directors discussed the possible business combination with Mykrolis and a possible transaction with another company. The chief executive officer of the other company had approached Mr. Dauwalter regarding a possible merger of equals transaction. The board of directors expressed a strong preference toward continuing to pursue discussions with Mykrolis. Management of Entegris believed, and the board of directors agreed, that Mykrolis offered a much better strategic fit with Entegris than did the company that was the subject of the other possible transaction discussed at the meeting.

 

On January 31, 2005, representatives of Mykrolis met with representatives of the other company that had entered into a non-disclosure agreement with Mykrolis to discuss the structure of a possible transaction and the potential synergies that could be realized. Following the January 31, 2005 meeting, Mykrolis established integration teams to identify potential synergies associated with such a transaction.

 

In January 2005, Mykrolis engaged Citigroup as its financial advisor to assist it in connection with the evaluation of strategic alternatives. This engagement was formalized in a letter dated March 10, 2005.

 

Throughout early 2005, management of Entegris and Mykrolis continued to exchange telephone calls and e-mail messages regarding the possible transaction, including numerous communications among Mr. Dauwalter, Stan Geyer, the chairman of the board of Entegris, and Mr. Argov. On February 1, 2005, Mr. Dauwalter, Mr. Argov and Mr. Geyer met for dinner in Chicago to discuss a possible business combination, the companies’ respective corporate cultures, and the expected benefits of a merger of equals.

Table of Contents

On February 2, 2005, a broader group of members of management of Entegris and Mykrolis met in Chicago to expand on the previous night’s discussions, exchange certain information and discuss the possible transaction. A third party facilitator attended the meeting and led a discussion about the expected strategic benefits of the proposed merger of equals and an initial discussion of the possible synergies that could be realized in the merger. Messrs. Argov, Walcott and Kirlin attended the meeting for Mykrolis, along with Bertrand Loy, Mykrolis’ vice president and chief financial officer, and Jean-Marc Pandraud, Mykrolis’ president and chief operating officer. Messrs. Dauwalter, Geyer, and Graves attended the meeting for Entegris, along with Michael W. Wright, Entegris’ president and chief operating officer, and John D. Villas, Entegris’ chief financial officer.

 

Following the February 2 meeting, Messrs. Argov, Dauwalter and Geyer continued to communicate by telephone and through e-mail to discuss the fundamental concepts upon which a merger of equals might be based.

 

On February 11, 2005, the Entegris board of directors held a special meeting by telephone to discuss the status of discussions with Mykrolis. Representatives of Goldman Sachs updated the board on the process to date, including describing the meetings between members of management that had occurred and the signing of non-disclosure agreements. Representatives of Goldman Sachs then discussed key next steps in the process, including exchanging due diligence materials, updating the financial analysis of the proposed transaction, finalizing decisions regarding the management and board structure of the combined company, agreeing on material contractual terms, negotiating the merger agreement and related documents, and commencing the planning for communication of the transaction to the public, employees, customers and suppliers. The board of directors authorized Entegris management to continue discussions with Mykrolis.

 

On February 11, 2005, representatives of Mykrolis’ senior management, along with representatives of Mykrolis’ financial advisor, met with the other industry participant with which Mykrolis had discussed a possible strategic transaction during which Messrs. Kirlin and Loy made a presentation to the other company and its financial advisor describing Mykrolis’ business and operations and the other company’s management made a similar presentation to Mykrolis and Citigroup describing its business and operations.

 

On February 16, 2005, Messrs. Dauwalter, Geyer and Argov met in Philadelphia to discuss the organizational structure for the combined company and began to identify the roles that senior management at each company would serve in the combined company if a transaction was completed.

 

On February 21, 2005, Messrs. Dauwalter and Wright had a dinner meeting with Messrs. Argov and Pandraud in Chicago. They had a preliminary discussion of the structure of the combined company, including possibilities for the composition of the board of directors and executive management team of the combined company. This meeting continued for most of the day on February 22.

 

On February 24, 2005, at a regularly scheduled meeting of the board of directors of Mykrolis at its corporate headquarters in Billerica, Massachusetts, Mr. Argov presented the merger proposal that he had developed with Messrs. Dauwalter and Geyer to the Mykrolis directors, including the proposed business structure, tactical and strategic synergies, a review of the discussions to date, key deal points and a review of Entegris’ history and product offerings. Also attending the meeting were representatives of Citigroup and Ropes & Gray LLP, Mykrolis’ outside legal advisors. Citigroup discussed its preliminary analysis of the two possible business combinations being explored by Mykrolis, one of which was the possible combination with Entegris and the other of which involved the other significant industry participant with which Mykrolis officers had recently had discussions. Mykrolis management did not express enthusiasm for a transaction with the other industry participant as a result of the lack of compelling product synergies between the two companies and because other envisioned synergies, upon closer examination, did not appear to be realizable. Mykrolis management, however, continued to support a possible transaction with Entegris. Ropes & Gray reviewed with the directors their fiduciary duties under Delaware law in connection with the proposed transaction, and the directors engaged in an extensive discussion of the proposed transaction with Entegris, asking questions and receiving answers from

management regarding the structure of the proposed transaction, the financial implications from the combination of the two businesses and the product and cost synergies that would be available. At the conclusion of this discussion, the board of directors authorized Mykrolis management to continue to investigate the potential benefits and risks of proceeding with a transaction with Entegris as described by Mr. Argov and directed Mykrolis management to terminate discussions with the other industry participant.

 

On February 24, 2005, following the board meeting, Mr. Argov notified the chief executive officer of the other company that Mykrolis was no longer interested in pursuing a strategic transaction with that company.

 

After the February 11, 2005, special meeting of the Entegris board of directors, the board had invited Mr. Argov to come to Minnesota to tour Entegris’ headquarters and meet with certain Entegris directors and members of management. Mr. Argov visited Entegris’ Chaska, Minnesota headquarters on February 25. Mr. Dauwalter led Mr. Argov on a tour of the facility and, after the tour, Mr. Argov met with Messrs. Dauwalter and Geyer, Jay Bennett from Dunkley and Bennett, P.A., Entegris’ outside counsel, and James A. Bernards, another member of the Entegris board of directors. The group then joined Paul Olson, another member of the Entegris board, for lunch. At both the meeting and the lunch, the discussions focused on the respective backgrounds and business philosophies of Mr. Argov and the participating Entegris directors.

 

On February 28, 2005, the parties held a large group meeting in Chicago attended by 34 people. In addition to senior management of Entegris and Mykrolis, representatives of Entegris’ legal advisors, Faegre & Benson LLP and Dunkley and Bennett, P.A., Mykrolis’ legal advisor, Ropes & Gray, Goldman Sachs, Citigroup, and other advisors of the parties attended the meeting. Each of Entegris and Mykrolis gave oral due diligence presentations to the other. Certain of the advisors then discussed the expected process for conducting due diligence and negotiating the merger agreement.

 

On March 1, 2005, management employees of both companies met to discuss possible synergies that could result from the proposed merger. Over the two-week period following that meeting, management employees of both companies communicated with one another by telephone and e-mail to exchange information and to identify cost savings and the steps necessary to achieve those savings.

 

In early March 2005, Mykrolis engaged Ernst & Young LLP to assist it with its due diligence review of Entegris, which arrangement was formalized in a letter dated March 7, 2005. Entegris engaged KPMG LLP in February 2005 to assist it with its due diligence review of Mykrolis, which arrangement was formalized in an engagement letter signed on March 10, 2005.

 

On March 3, 2005, Entegris held a special meeting of the board of directors to update the directors on the status of discussions with Mykrolis and receive the directors’ views on open issues. Mr. Dauwalter and representatives of Goldman Sachs described the February 28 large group meeting, discussions between the parties to date, the due diligence conducted to date by each party and the status of negotiations between the parties. Representatives of Goldman Sachs also orally reviewed with the board of directors its updated financial analysis of the proposed transaction. Representatives of Faegre & Benson discussed the terms of the draft merger agreement it had prepared with input from Entegris management and reviewed with the directors their fiduciary duties under Minnesota law in connection with the proposed transaction. The Entegris board authorized Entegris management to continue its discussions and negotiations with Mykrolis. After the meeting, Faegre & Benson circulated Entegris’ draft of the merger agreement to Mykrolis and Ropes & Gray. The draft merger agreement contained the terms of a proposed tax-free, stock-for-stock merger of equals transaction.

 

Legal advisors for the parties were then in regular contact to discuss and negotiate the merger agreement and related documents and to discuss the due diligence process. Ropes & Gray delivered Mykrolis’ markup of the merger agreement to Faegre & Benson on March 11. Various revised drafts of the merger agreement and its exhibits and schedules were then exchanged by the parties’ legal advisors throughout the week of March 14.

On March 14, 2005, each party sent teams of outside attorneys and accountants to the legal advisor’s offices of the other party to conduct due diligence. The legal advisors’ offices contained “data rooms” with extensive financial, legal and other documents and information about the applicable company and its operations, assets, liabilities, employees, and financial condition, among other areas. This due diligence review of the parties’ data rooms and other due diligence investigations by the parties continued throughout the week of March 14, during which time the terms of the merger agreement were also being negotiated.

 

Also on March 14, members of management of each of Mykrolis and Entegris met again to discuss potential synergies between Mykrolis and Entegris.

 

On March 16, 2005, the Entegris board of directors held a special meeting to discuss the transaction. Entegris management began the meeting with a presentation updating the Entegris board of directors on the transaction process to date, the status of negotiations with Mykrolis, the material issues remaining to be resolved, and management’s views on a possible merger with Mykrolis. Entegris management and the Entegris board then discussed the reasons for the proposed merger. Mr. Argov then joined the meeting at the invitation of Entegris management and the board. He discussed the strategic benefits he saw in a merger of equals between Mykrolis and Entegris and his vision of the combined company’s future. Mr. Argov then left the meeting, and representatives of Goldman Sachs reviewed with the board of directors its financial analysis of the possible merger. Representatives of Faegre & Benson then described certain terms and conditions of the proposed merger agreement and the proposed reincorporation merger agreement, as well as remaining open issues in the merger agreement, to the Entegris board of directors. The directors instructed management and the Entegris advisors concerning the negotiation of the remaining open issues. At the conclusion of the meeting, the Entegris board authorized Entegris management to continue discussions and negotiations with Mykrolis regarding a possible merger.

 

On March 17, 2005, the Mykrolis board of directors held a telephonic meeting that included senior management as well as representatives of Ropes & Gray and Citigroup. At the meeting, Mr. Argov and other members of management reported to the board on the parties’ discussions relating to possible synergies and updated the board on the progress of due diligence and the negotiation of the merger agreement. The directors also reviewed a summary of the proposed transaction and the financial model for the combined entity prepared by Citigroup. Ropes & Gray also presented to the directors a detailed review of the terms of the draft merger agreement and answered questions from the directors concerning certain terms and provisions of the draft merger agreement. As a result of these deliberations, the directors authorized Mykrolis management to proceed to negotiate a definitive merger agreement with Entegris.

 

Over the course of the next few days, Entegris and Mykrolis and outside counsel continued discussions to resolve open issues. On March 19, the parties reached an understanding regarding the remaining material unresolved terms of the merger, including the exchange ratio. However, the parties’ due diligence investigations and the finalization of the merger agreement continued until March 20.

 

On March 19, 2005, the management development and compensation committee of the Mykrolis board of directors met at Mykrolis’ headquarters in Billerica, Massachusetts, to consider certain compensation arrangements for management in connection with the proposed transaction and to consider certain other matters. Also attending the committee meeting by telephone was a representative of Mercer Human Resource Consulting, the board’s compensation consultant. At this meeting, Mr. Argov provided an update concerning the progress of the negotiation of the merger agreement and the results of the due diligence inquiry. The committee asked questions of, and received answers from, Mercer Human Resources Consulting concerning the terms of the proposed compensation arrangements, including the proposed amended and restated executive termination agreements, restricted stock awards and other employment terms to be included in employment letter agreements to be provided to Mykrolis management employees in connection with the proposed merger of equals transaction. Following a discussion, the committee recommended that such arrangements be approved by the full Mykrolis board.

At a special telephonic meeting of the Entegris board of directors on March 20, 2005, management of Entegris reviewed the results of Entegris’ and its advisors’ due diligence investigation of Mykrolis; management and representatives of Faegre & Benson and Goldman Sachs described how the parties resolved the exchange ratio and other open issues; Entegris management and advisors responded to questions from the Entegris directors on various due diligence and other matters; and representatives of Goldman Sachs reviewed with the board of directors its updated financial analysis of the proposed merger and, following such discussion and review, Goldman Sachs rendered its oral opinion, subsequently confirmed by delivery of its written opinion dated March 21, 2005, to Entegris’ board of directors that, as of such date and based upon and subject to the factors and assumptions set forth therein, the exchange ratio of 1.39 shares of common stock of Entegris Delaware to be issued in exchange for each share of common stock of Mykrolis pursuant to the merger agreement is fair from a financial point of view to Entegris. Management of Entegris and representatives of Faegre & Benson also discussed with the board proposed amended and restated executive termination agreements and employment letter agreements that Mykrolis planned to execute with certain of its officers who are expected to serve as officers of Entegris Delaware following the merger and the fact that Entegris Delaware would be assuming Mykrolis’ obligations under those agreements by operation of law in connection with the merger. After due consideration, the Entegris board of directors determined that the merger agreement and the reincorporation merger agreement and the transactions contemplated by each of them are advisable, fair to and in the best interests of Entegris’ stockholders, unanimously approved the merger agreement and the reincorporation merger agreement and the transactions contemplated by each of them, authorized their execution and delivery and the execution and delivery of related documents, and resolved to recommend to Entegris stockholders that they approve and adopt the merger agreement and the merger and the reincorporation merger agreement and the reincorporation merger. The Entegris Delaware board of directors then approved the merger agreement, the reincorporation merger agreement and the related matters discussed in this joint proxy statement/prospectus.

 

On March 20, 2005, the Mykrolis board of directors held a special meeting in Boston, Massachusetts to consider the proposed merger of equals with Entegris. The meeting was attended in person by all directors except Michael A. Bradley, who attended by telephone, as well as by certain members of management, representatives of Ropes & Gray, representatives of Citigroup, representatives of Ernst & Young, who had assisted Mykrolis in the conduct of its financial due diligence, and a representative of Mercer Human Resource Consulting, the board’s compensation consultant. At the meeting, the directors reviewed and analyzed the strategic, financial and legal considerations concerning the proposed transaction, the advisability of the proposed transaction and the fairness of the proposed exchange ratio, and received reports concerning the financial and legal due diligence inquiry of Entegris. During the meeting, Ropes & Gray reviewed with the Mykrolis board its legal obligations, including its fiduciary duties, and summarized the terms of the most recent draft of the merger agreement, which had been previously distributed to the board, and Mr. Walcott reviewed the terms and conditions of the new employment letters and revised change of control agreements with certain Mykrolis executives. In addition, Citigroup delivered its oral opinion, which was subsequently confirmed in writing, that, as of March 20, 2005 and subject to the assumptions and limitations set forth in the written opinion, the proposed exchange ratio was fair from a financial point of view to the holders of Mykrolis common stock. The Mykrolis board discussed the terms of the merger agreement and asked its financial, legal and compensation advisors various questions regarding the proposed merger. Following these discussions, the Mykrolis board determined that the merger agreement and the transactions contemplated thereby are advisable, are fair to, and in the best interests of, Mykrolis and the Mykrolis stockholders and unanimously approved the merger, authorized the execution and delivery of the merger agreement and any related agreements, and recommended that Mykrolis stockholders approve and adopt the merger agreement and the merger.

 

On March 21, 2005, Mykrolis entered into amended and restated executive termination agreements with each of Messrs. Pandraud, Loy and Walcott as well as Fred E. Faulkner, Jr., Mykrolis’ vice president of worldwide manufacturing, Gerry Mackay, Mykrolis’ vice president of worldwide sales and marketing, and Takashi Mizuno, Mykrolis’ vice president and president of Mykrolis’ Japanese subsidiary, and entered into an executive termination agreement with Mr. Kirlin on substantially the same terms. In addition, Mykrolis entered into employment letter agreements dated as of March 21, 2005 with each of Messrs. Argov, Pandraud, Loy,

Walcott, Faulkner, Mackay and Mizuno outlining the duties, title, salary and benefits, including a restricted stock award, planning bonus and integration project bonus, to be made available to such executives by the surviving corporation following the merger.

 

Following the approval of their boards of directors, Entegris, Entegris Delaware and Mykrolis executed the merger agreement and Entegris and Entegris Delaware executed the reincorporation merger agreement, in each case as of March 21, 2005. The parties issued a joint press release announcing the transaction on the morning of March 21 before the opening of trading on the New York Stock Exchange and The NASDAQ National Market.

 

Recommendation of Entegris’ Board of Directors; Entegris’ Reasons for the Merger

 

The Entegris board believes that the merger is advisable, fair to, and in the best interests of, Entegris and its stockholders. Accordingly, the Entegris board has unanimously approved the merger agreement and the merger and unanimously recommends that Entegris stockholders vote:

    “FOR” approval of the reincorporation of Entegris into a Delaware corporation pursuant to the reincorporation merger agreement and the approval and adoption of the reincorporation merger agreement, including the adoption of the proposed certificate of incorporation and proposed bylaws attached hereto as Annex C-1 and Annex D, respectively; and

 

    “FOR” approval of a classified board for Entegris Delaware.

 

The Entegris board, in reaching its decision to approve the merger agreement and the merger and the other proposals listed above, consulted with its management, as well as with its financial and legal advisors, reviewed a significant amount of information and considered a variety of factors, including the following:

 

    information concerning the business, operations, financial condition, earnings and prospects of Entegris as a separate entity and on a combined basis with Mykrolis, including their revenues, their complementary businesses and the potential for revenue enhancement and cost savings;

 

    the enhanced strategic and market position of the combined company beyond that achievable by Entegris alone;

 

    the increased volume, geographical expansion and diversity of operations, product lines, served markets and customers that could be achieved by combining Mykrolis and Entegris;

 

    the opportunity for the combined company to combine complementary technologies to produce a more extensive set of materials integrity management solutions for their customers;

 

    the increased capability of the combined company to generate cash that could increase the ability of the combined company to expand through significant acquisitions;

 

    the opportunity for Entegris stockholders to remain stockholders in a company that would be substantially larger as a result of the merger with a more diversified product line, a broader customer base and enhanced technology capabilities, and to benefit from future growth of the combined company;

 

    the belief of the Entegris board of directors that, as a result of its scale, the combined company would have a stronger foundation for competing globally, particularly given the strength of Mykrolis in Japan;

 

    the belief of the Entegris board of directors that the subsystems, components and materials segment of the semiconductor industry is entering a consolidation phase and that the combined company, because of its scale and breadth of operations, would be in a better position to lead this consolidation;

    the potential impact of the merger on Mykrolis and Entegris customers;

 

    the provisions in the merger agreement that permit Entegris’ board of directors to withdraw its recommendation of the merger agreement and to respond to unsolicited third-party proposals, and the belief of the Entegris board of directors, after consultation with its legal counsel and financial advisors, that these provisions, notwithstanding the obligation to hold a stockholder meeting even if the board changes or withdraws its recommendation, and the obligation to pay termination fees and reimburse expenses of the other party under certain circumstances, should not preclude the possibility of considering any competing transactions;

    the structure of the merger and the terms of the merger agreement, which are reciprocal in nature, including the fact that the fixed exchange ratio provides certainty as to the number of shares of Entegris Delaware common stock to be issued in the merger;

 

    the fact that the Entegris stockholders would hold approximately 56% of the outstanding common stock of the combined company after the merger;

 

    current financial market conditions and historical market prices, volatility and trading information with respect to Entegris common stock and Mykrolis common stock;

 

    the combined company’s anticipated future financial performance;

 

    the fact that the exchange ratio negotiated with Mykrolis did not provide a premium to the Mykrolis stockholders as compared to the average closing trading prices of Mykrolis common stock during the ten-day trading period preceding the execution of the merger agreement and provided an approximately 5% premium to the closing sale price on the last trading day prior to execution of the merger agreement;

 

    the limited overlap of the product lines of Entegris and Mykrolis;

 

    the opinion of Goldman, Sachs & Co., Entegris’ financial advisor, that, as of the date of the opinion and based on and subject to the assumptions, factors and limitations set forth in the opinion, the exchange ratio was fair from a financial point of view to Entegris (see “Opinion of Entegris’ Financial Advisor”);

 

    the fact that the mergers will be tax-free to Entegris stockholders for U.S. federal income tax purposes; and

 

    other potential strategic opportunities.

 

Entegris’ board of directors also identified and considered certain countervailing factors in its deliberations concerning the merger and the other transactions contemplated by the merger agreement, including:

 

    the possibility that the expected benefits from the merger might not be fully realized;

 

    the possibility that the merger may not be consummated and the potential adverse consequences if the merger is not completed;

 

    the risk that the per share value of the consideration to be paid in the merger to the Mykrolis stockholders could increase significantly from the value prior to the announcement of the merger agreement because the exchange ratio will not be adjusted for changes in the market price of Entegris common stock or Mykrolis common stock;

    the risk that key management and other personnel might not remain employed by the combined company; and

 

    the contractual restrictions on the ability of Mykrolis to expand certain product sales into new markets and the short-term expiration of certain Mykrolis contracts.

 

The foregoing discussion is not exhaustive of all factors considered by the Entegris board of directors. Moreover, in view of the variety of factors considered in connection with its evaluation of the merger agreement and the merger, the Entegris board of directors considered the factors as a whole and did not find it practicable to, and did not, quantify or otherwise assign relative weight to the specific factors considered in reaching its determination to approve the merger agreement and the merger. In addition, each member of the Entegris board of directors may have given differing weights to different factors.

Opinion of Entegris’ Financial Advisor

 

On March 20, 2005, Goldman Sachs rendered its oral opinion, subsequently confirmed by delivery of its written opinion dated March 21, 2005, to Entegris’ board of directors that, as of such date and based upon and subject to the factors and assumptions set forth therein, the exchange ratio of 1.39 shares of Entegris Delaware common stock to be issued in exchange for each share of Mykrolis common stock pursuant to the merger agreement is fair from a financial point of view to Entegris.

 

The full text of the written opinion of Goldman Sachs, dated March 21, 2005, which sets forth assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex E to this joint proxy statement/prospectus. Goldman Sachs provided its opinion for the information and assistance of Entegris’ board of directors in connection with its consideration of the transaction contemplated by the merger agreement. The Goldman Sachs opinion is not a recommendation as to how any holder of Entegris’ common stock should vote with respect to the transaction.

 

In connection with rendering the opinion described above and performing its related financial analyses, Goldman Sachs reviewed, among other things:

 

    the merger agreement;

 

    the reincorporation merger agreement;

 

    annual reports to stockholders and Annual Reports on Form 10-K of Entegris for the five fiscal years ended August 28, 2004, and Mykrolis for the four fiscal years ended December 31, 2004;

 

    interim reports to stockholders and Quarterly Reports on Form 10-Q of Entegris and Mykrolis;

 

    other communications from Entegris and Mykrolis to their respective stockholders;

 

    certain internal financial analyses and forecasts for Mykrolis prepared by its management; and

 

    certain financial analyses and forecasts for Entegris and for Mykrolis prepared by the management of Entegris, including certain cost savings and operating synergies projected by the management of each of Entegris and Mykrolis to result from the transactions contemplated by the merger agreement.

 

Goldman Sachs also held discussions with members of the senior management of each of Entegris and Mykrolis regarding their assessment of the strategic rationale for, and the potential benefits of, the transaction

contemplated by the merger agreement and the past and current business operations and financial condition, and future prospects, of Entegris and Mykrolis. In addition, Goldman Sachs reviewed the reported price and trading activity for the shares of Entegris common stock and the shares of Mykrolis common stock, compared certain financial and stock market information for Entegris and Mykrolis with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the semiconductor industry specifically and in other industries generally and performed such other studies and analyses, and considered such other factors, as it considered appropriate.

 

Goldman Sachs relied upon the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by it and assumed such accuracy and completeness for purposes of rendering its opinion. In that regard, Goldman Sachs assumed with Entegris’ consent that the financial analyses and forecasts for Entegris and for Mykrolis prepared by the management of Entegris, including the cost savings and operating synergies projected by the management of Entegris and Mykrolis to result from the transaction contemplated by the merger agreement, were reasonably prepared on a basis reflecting the best currently available estimates and judgments of Entegris. In addition, Goldman Sachs did not make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of Entegris or Mykrolis or any of their respective subsidiaries, and Goldman Sachs was not furnished with any such evaluation or appraisal. Goldman Sachs also assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the transaction will be obtained without any adverse effect on Entegris or Mykrolis or on the expected benefits of the transaction in any way meaningful to its analysis. The Goldman Sachs opinion does not address the underlying business decision of Entegris to engage in the transaction contemplated by the merger agreement. In addition, Goldman Sachs did not express any opinion as to the prices at which shares of Entegris common stock or Entegris Delaware common stock will trade at any time.

 

The following is a summary of the material financial analyses used by Goldman Sachs in connection with rendering the opinion described above. The following summary, however, does not purport to be a complete description of the financial analyses performed by Goldman Sachs. The order of analyses described does not represent relative importance or weight given to those analyses by Goldman Sachs. Some of the summaries of the financial analyses include information presented in tabular format. The tables must be read together with the full text of each summary and are alone not a complete description of Goldman Sachs’ financial analyses. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before March 18, 2005, and is not necessarily indicative of current market conditions.

 

Historical Stock Trading and Exchange Ratio Analysis. Goldman Sachs reviewed the historical stock prices for Entegris common stock and Mykrolis common stock on the basis of their respective closing prices per share on March 18, 2005, and the respective period averages for the prior 5 days, 10 days, 15 days, 30 days, 60 days, 90 days and 180 days. The following table presents:

 

    The implied average exchange ratio between the closing prices of Entegris common stock and Mykrolis common stock on March 18, 2005, and the implied average exchange ratios calculated based on the average of the ratios between the closing prices of Entegris common stock and the closing prices of Mykrolis common stock on each day for the specified periods. “Implied average exchange ratio” means the number of shares of Entegris common stock that would be equal in value to one share of Mykrolis common stock based on the closing price data applicable to the given date or period.

 

    The premium (discount) to the implied average exchange ratio, which is equal to the percentage by which the exchange ratio pursuant to the merger agreement (1.39 shares of Entegris Delaware common stock for each share of Mykrolis common stock) exceeds (is less than) the implied average exchange ratio.

Multiples Analysis. Goldman Sachs calculated various financial ratios based on the merger agreement exchange ratio, information it obtained from filings with the Securities and Exchange Commission, estimates of Mykrolis’ revenue and earnings per share, or EPS, for calendar years 2005 and 2006 prepared by Entegris’ management and provided by the Institutional Brokers Estimate System, or IBES. The multiples analysis summarized below is based on an implied Mykrolis offer price of $13.80 per share, calculated as the product of the exchange ratio of 1.39 shares of Entegris Delaware common stock for each share of Mykrolis common stock and $9.93 (the closing price of Entegris common stock on March 18, 2005), 43.7 million diluted shares of Mykrolis common stock outstanding as of February 2005, and net cash of Mykrolis of $130.4 million as of December 31, 2004.

 

Using Entegris’ management estimates:

 

    levered consideration, which is the aggregate implied consideration payable pursuant to the merger agreement plus the book value of Mykrolis’ debt less cash, is a multiple of 1.8 of Mykrolis’ estimated calendar year 2005 revenue;

 

    levered consideration is a multiple of 1.9 of Mykrolis’ estimated calendar year 2006 revenue;

 

    the implied Mykrolis offer price per share is a multiple of 19.8 of Mykrolis’ estimated calendar year 2005 EPS; and

 

    the implied Mykrolis offer price per share is a multiple of 18.4 of Mykrolis’ estimated calendar year 2006 EPS.

 

Using IBES estimates:

 

    levered consideration is a multiple of 1.7 of Mykrolis’ estimated calendar year 2005 revenue;

 

    levered consideration is a multiple of 1.5 of Mykrolis’ estimated calendar year 2006 revenue;

 

    the implied Mykrolis offer price per share is a multiple of 24.6 of Mykrolis’ estimated calendar year 2005 EPS; and

 

    the implied Mykrolis offer price per share is a multiple of 19.2 of Mykrolis’ estimated calendar year 2006 EPS.

 

In addition, Goldman Sachs calculated certain historical financial multiples for Entegris and Mykrolis using information it obtained from filings with the Securities and Exchange Commission and the IBES. For the two years ended March 18, 2005, Goldman Sachs calculated:

 

    the ratio of enterprise value, which is the market value of the common equity plus the book value of debt less cash, as a multiple of estimated revenue for the next four quarters as estimated by the IBES; and

 

    the ratio of stock price to estimated EPS for the next four quarters as estimated by the IBES.

Contribution Analysis. Goldman Sachs analyzed and compared the implied percentage contribution of each of Entegris and Mykrolis for the last fiscal quarter prior to the date of Goldman Sachs’ opinion (the fiscal quarter ended February 26, 2005, for Entegris and the fiscal quarter ended December 31, 2004, for Mykrolis) and calendar year 2004, and the implied estimated percentage contribution of each of Entegris and Mykrolis for 2005 and 2006 to pro forma revenue, earnings before interest and taxes, or EBIT, and adjusted net income (adjusted to eliminate certain non-cash charges and other items) as estimated by Entegris management. The contribution percentages were adjusted for differences in the capital structures of Entegris and Mykrolis by applying Entegris revenue, gross margin and operating income multiples to revenue, EBIT and adjusted net income of Entegris and Mykrolis to derive implied enterprise values for each of Entegris and Mykrolis. These implied enterprise values were adjusted by subtracting cash less the book value of debt, or net cash, of each of Entegris and Mykrolis to derive implied equity contributions for each of Entegris and Mykrolis. The following table presents the results of this analysis:

Goldman Sachs also calculated the estimated percentage ownership of the combined company on a pro forma basis by the Entegris stockholders and the Mykrolis stockholders based on the exchange ratio of 1.39 shares of Entegris Delaware common stock for each share of Mykrolis common stock. The results of this analysis implied that 44.1% of the outstanding shares of Entegris Delaware common stock would be owned by former Mykrolis stockholders and 55.9% would be owned by former Entegris stockholders.

 

Give/Get Analysis. Based on estimates by Entegris management of net income for Entegris and Mykrolis for calendar years 2005 and 2006 and of the after-tax synergies that could be realized by the combined company in calendar years 2005 and 2005, and based on the implied ownership by former Entegris stockholders of 55.9% of

Table of Contents

the combined company and by former Mykrolis stockholders of 44.1% of the combined company, Goldman Sachs calculated the implied increase or decrease in net income attributable to the former Entegris and Mykrolis stockholders as compared to the net income of Entegris and Mykrolis on a stand-alone basis. The results of this analysis implied an estimated increase in the net income attributable to Entegris stockholders of $7.6 million in calendar year 2005 and $10.4 million in calendar year 2006.

 

Pro Forma Transaction Analysis. Goldman Sachs prepared pro forma analyses of the financial impact of the transaction using publicly available information, estimates prepared by Entegris management and selected Wall Street research estimates. Goldman Sachs analyzed the pro forma financial impact of the transaction on Entegris’ estimated EPS and the amount of accretion/dilution on a per share basis. Goldman Sachs prepared this analysis assuming no synergies resulting from the merger and also assuming $15 million in annual pre-tax synergies resulting from the merger. Goldman Sachs calculated the implied accretion/dilution to Entegris using both Entegris management estimates and Wall Street research (IBES estimates, in the case of Mykrolis, and recent published research analysts’ reports, in the case of Entegris). EPS used to calculate accretion/dilution was adjusted to exclude certain non-cash charges and other items based on information provided by Entegris management.

Although none of the selected companies is directly comparable to Entegris or Mykrolis, the companies included were chosen because they are publicly traded companies with operations that for purposes of analysis may be considered similar to certain operations of Entegris and/or Mykrolis.

 

Goldman Sachs calculated and compared various financial multiples and ratios of Entegris and Mykrolis to the corresponding multiples and ratios of the selected companies. The multiples and ratios of Entegris and Mykrolis were calculated based on financial data and the closing share prices as of March 18, 2005, and the multiples and ratios for each of the selected public companies were based on certain recent published research estimates, in the case of Entegris, and IBES estimates, in the case of each of the other companies. With respect to the selected companies, Goldman Sachs calculated:

 

    the enterprise value as a multiple of calendar years 2005 and 2006 estimated revenue;

 

    the ratio of stock price to estimated EPS for calendar years 2005 and 2006;

 

    the five-year forecasted compound annual growth rate, or CAGR, of EPS, which is the forecasted rate at which EPS grows year over year, based on a five-year projection of EPS;

 

    the ratio of stock price to calendar year 2006 EPS as a multiple of the five-year CAGR of earnings per share, or PEG;

 

    the percentage revenue growth between calendar years 2005 and 2006; and

 

    gross margin as a percentage of revenue for the most recently completed fiscal quarter.

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs’ opinion. In arriving at its fairness determination, Goldman Sachs considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis considered by it. Rather, Goldman Sachs made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. No company or transaction used in the above analyses as a comparison is directly comparable to Entegris or Mykrolis or the contemplated transaction.

 

Goldman Sachs prepared these analyses for purposes of Goldman Sachs providing its opinion to Entegris’ board of directors as to the fairness from a financial point of view of the exchange ratio. These analyses do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may

 

52


Table of Contents

be significantly more or less favorable than suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of Entegris, Mykrolis, Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecast.

 

As described above, Goldman Sachs’ opinion to the Entegris board of directors was one of many factors taken into consideration by Entegris’ board of directors in making its determination to approve the merger agreement. The foregoing summary does not purport to be a complete description of the analyses performed by Goldman Sachs in connection with the fairness opinion and is qualified in its entirety by reference to the written opinion of Goldman Sachs attached as Annex E to this joint proxy statement/prospectus.

 

Goldman Sachs and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions, as well as for estate, corporate and other purposes. Goldman Sachs has acted as financial advisor to Entegris in connection with, and has participated in certain of the negotiations leading to, the transaction contemplated by the merger agreement. Goldman Sachs may provide investment banking services to Entegris or Mykrolis in the future. In connection with such investment banking services, Goldman Sachs may receive compensation.

 

Goldman Sachs is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman Sachs and its affiliates may provide such services to Entegris, Mykrolis and their respective affiliates, may actively trade the debt and equity securities (or related derivative securities) of Entegris and Mykrolis for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.

 

The Entegris board of directors selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the transactions contemplated by the merger agreement. Pursuant to a letter agreement dated as of October 7, 2004, Entegris engaged Goldman Sachs to act as its financial advisor in connection with the contemplated transaction. Pursuant to the terms of this engagement letter, Entegris has agreed to pay Goldman Sachs a transaction fee of $5,500,000, all of which is payable upon consummation of the transaction contemplated by the merger agreement and is only payable in the event of consummation of the transaction. In addition, Entegris has agreed to reimburse Goldman Sachs for its reasonable expenses, including attorneys’ fees and disbursements, and to indemnify Goldman Sachs and related persons against various liabilities, including certain liabilities under the federal securities laws.

 

Opinion of Mykrolis’ Financial Advisor

 

Citigroup was retained to act as financial advisor to Mykrolis in connection with the merger. Pursuant to Mykrolis’ engagement letter agreement with Citigroup, dated March 10, 2005, Citigroup rendered an opinion to the Mykrolis board of directors on March 20, 2005, to the effect that, as of the date of the opinion, and based upon and subject to the considerations and limitations set forth in the opinion, Citigroup’s work described below and other factors Citigroup deemed relevant, the exchange ratio in the merger was fair, from a financial point of view, to the holders of shares of Mykrolis common stock.

 

The full text of Citigroup’s opinion, which sets forth the assumptions made, general procedures followed, matters considered and limits on the review undertaken, is included as Annex F to this document. The summary of Citigroup’s opinion set forth below is qualified in its entirety by reference to the full text of the opinion. Holders of Mykrolis common stock are urged to read the Citigroup opinion carefully and in its entirety.

Table of Contents

The Citigroup opinion was limited solely to the fairness of the exchange ratio in the merger from a financial point of view as of the date of the opinion. Neither the Citigroup opinion nor the related analyses constituted a recommendation of the merger to the Mykrolis board of directors. Citigroup makes no recommendation to any stockholder regarding how such stockholder should vote with respect to the merger.

 

In arriving at its opinion, Citigroup reviewed a draft of the merger agreement dated March 19, 2005 and held discussions with certain senior officers, directors and other representatives and advisors of Mykrolis and certain senior officers and other representatives and advisors of Entegris concerning the businesses, operations and prospects of Mykrolis, Entegris and Entegris Delaware. Citigroup examined certain publicly-available business and financial information relating to Mykrolis and Entegris as well as certain financial forecasts and other information and data relating to Mykrolis, Entegris and Entegris Delaware which were provided to, or discussed with, Citigroup by the respective management of Mykrolis and Entegris. Citigroup reviewed the financial terms of the merger as set forth in the merger agreement in relation to, among other things:

 

    the current and historical market prices and trading volumes of Mykrolis common stock and Entegris common stock;

 

    the historical and projected earnings and other operating data of Mykrolis, Entegris and Entegris Delaware; and

 

    the capitalization and financial condition of Mykrolis and Entegris.

 

Citigroup analyzed certain financial, stock market and other publicly-available information relating to the businesses of other companies whose operations Citigroup considered relevant in evaluating those of Mykrolis and Entegris. Citigroup also evaluated certain potential pro forma financial effects of the merger on Entegris Delaware. In addition to the foregoing, Citigroup conducted such other analyses and examinations and considered such other information and financial, economic and market criteria as Citigroup deemed appropriate in arriving at its opinion.

 

In rendering its opinion, Citigroup assumed and relied upon, without assuming any responsibility for independent verification of, the accuracy and completeness of all financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with it and upon the assurances of the respective management of Mykrolis and Entegris that they were not aware of any relevant information that had been omitted or remained undisclosed to Citigroup. With respect to the financial forecasts and other information and data relating to Mykrolis, Entegris and Entegris Delaware provided to or otherwise reviewed or discussed by it, Citigroup was advised, by the respective management of Mykrolis and Entegris that such forecasts and other information and data were reasonably prepared on bases reflecting the best currently available estimates and judgments of the respective management of Mykrolis and Entegris as to the future financial performance of Mykrolis, Entegris and Entegris Delaware, and other matters covered thereby, and Citigroup assumed, with the consent of the Mykrolis board of directors, that the financial results reflected in such forecasts and other information and data will be realized in the amounts and at the times projected. Citigroup assumed, with the consent of the Mykrolis board of directors, that each of the planned reincorporation of Entegris and the merger will be consummated in accordance with its terms, without waiver, modification or amendment of any material term, condition or agreement and that, in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the reincorporation of Entegris and the merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on Mykrolis, Entegris, Entegris Delaware or the contemplated benefits of the reincorporation of Entegris or the merger. Representatives of Mykrolis advised Citigroup, and Citigroup further assumed, that the final terms of the merger agreement would not vary materially from those set forth in the draft Citigroup reviewed. Citigroup assumed, with the consent of the Mykrolis board of directors, that the merger will be treated as a tax-free reorganization for federal income tax purposes.

 

Citigroup noted that its opinion relates in part to the relative values of Mykrolis and Entegris. Citigroup did not express any opinion as to what the value of Entegris Delaware common stock actually will be when issued

pursuant to the merger or the price at which the Entegris Delaware common stock will trade at any time. Citigroup did not make and was not provided with an independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of Mykrolis or Entegris, nor did Citigroup make any physical inspection of the properties or assets of Mykrolis or Entegris.

 

In connection with rendering its opinion, Citigroup was not requested to consider, and its opinion did not address, the relative merits of the merger as compared to any alternative business strategies that might exist for Mykrolis or the effect of any other transaction in which Mykrolis might engage. Citigroup’s opinion was necessarily based upon information available to it, and financial, stock market and other conditions and circumstances existing, as of the date of its opinion.

 

In connection with rendering its opinion, Citigroup made a presentation to the Mykrolis board of directors on March 20, 2005, with respect to the material analyses performed by Citigroup in evaluating the fairness to the holders of Mykrolis common stock of the exchange ratio as of that date. The following is a summary of that presentation. The summary includes information presented in tabular format. In order to understand fully the financial analyses used by Citigroup, these tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. The following quantitative information, to the extent it is based on market data, is, except as otherwise indicated, based on market data as it existed at or prior to March 18, 2005, and is not necessarily indicative of current or future market conditions.

 

Implied Historical Exchange Ratio. Citigroup derived implied historical exchange ratios by dividing the closing price per share of Mykrolis common stock by the closing price per share of Entegris common stock for each trading day in the period from March 19, 2004, through March 18, 2005, the last trading day before the announcement of the merger between Mykrolis and Entegris. Such derived exchange ratios are referred to below as historical exchange ratios. Citigroup calculated the high, low and average historical exchange ratios for:

 

    the 5 trading day period ended March 18, 2005;

 

    the 10 trading day period ended March 18, 2005;

 

    the 30 trading day period ended March 18, 2005;

 

    the 60 trading day period ended March 18, 2005;

 

    the 6-month period ended March 18, 2005; and

 

    the 12-month period ended March 18, 2005.

 

The following table sets forth the results of those calculations:

 

     High

     Low

     Average

 

5 Trading Days Ended March 18, 2005

   1.4082 x    1.3243 x    1.3765 x

10 Trading Days Ended March 18, 2005

   1.4154      1.3243      1.3926  

30 Trading Days Ended March 18, 2005

   1.4485      1.3243      1.4034  

60 Trading Days Ended March 18, 2005

   1.4943      1.3243      1.4051  

6 Months Ended March 18, 2005

   1.4943      1.0658      1.2970  

12 Months Ended March 18, 2005

   1.5748      1.0479      1.2950  

 

Citigroup also derived the historical exchange ratio as of March 18, 2005, the last trading day prior to the announcement of the merger, which was 1.3243x.

 

Citigroup compared the high, low and average historical exchange ratios for each of the periods above to the exchange ratio in the merger of 1.39x. Citigroup noted that the exchange ratio in the merger was in the range between the high and low historical exchange ratios for each of the 5-trading-day period ended March 18, 2005, the 10-trading-day period ended March 18, 2005, the 30-trading-day period ended March 18, 2005, the 60- trading-day

period ended March 18, 2005, the 6-month period ended March 18, 2005, and the 12-month period ended March 18, 2005. Citigroup further noted that the exchange ratio in the merger was higher than the average historical exchange ratio for all periods considered other than the 10-trading-day period ended March 18, 2005 (to which, after mathematical rounding, the exchange ratio in the merger was equal), the 30-trading-day period ended March 18, 2005, and the 60-trading-day period ended March 18, 2005.

 

Relative Contribution Analysis. Citigroup reviewed certain historical market and historical and estimated operating and financial information for Mykrolis and Entegris, and based on this, derived the relative contribution of Mykrolis and Entegris to the combined company for certain market, operating and financial performance metrics. The operating and financial performance metrics were analyzed based on calendar years. In addition to publicly-available historical information and closing common stock prices as of March 18, 2005, this analysis was based on management estimates of each company for 2005 and 2006 revenues, gross profit, earnings before interest and taxes (EBIT) and net income. EBIT and net income were adjusted by Citigroup to exclude non-recurring items, and net income was adjusted to exclude amortization of intangible assets. In the course of this analysis, Citigroup did not take into account synergies or other benefits expected to result from the merger and, in determining exchange ratios, considered each of Mykrolis’ and Entegris’ current indebtedness and cash position. For the purposes of all its analyses, Citigroup defined firm value as the sum of:

 

    all shares of common stock, assuming the exercise of all in-the-money options, warrants and convertible securities, less the proceeds from such exercise (referred to as Equity Value); plus

 

    non-convertible indebtedness; plus

 

    non-convertible preferred stock; plus

 

    minority interest; plus

 

    out-of-the-money convertibles; minus

 

    investments in unconsolidated affiliates and restricted and unrestricted cash.

 

Based on this information, Citigroup derived a set of implied exchange ratios, and compared the results to the merger exchange ratio of 1.39x. Citigroup’s analysis is set forth in the table below.

Based on its contribution analysis, Citigroup derived a range for the implied exchange ratio of 1.30x to 1.70x. Citigroup noted that the exchange ratio in the merger of 1.39x was within this derived range.

 

Comparable Companies Valuation. Citigroup compared financial, operating and stock market data and forecasted financial information for selected publicly traded companies that supply materials and capital equipment to semiconductor device manufacturers that Citigroup deemed appropriate with similar information for each of Mykrolis and Entegris on a stand-alone basis. Citigroup divided the selected comparable companies into three groups: (a) consumables companies, (b) sub-systems companies and (c) large capitalization companies. The selected comparable companies considered by Citigroup were:

 

Consumables Companies:

 

    ATMI, Inc.;

 

    Cabot Microelectronics Corp.;

 

Sub-systems Companies:

 

    Advanced Energy Industries, Inc.;

 

    Helix Technology Corp.;

 

    MKS Instruments, Inc.;

 

    Ultra Clean Holdings, Inc.;

 

Large Capitalization Companies:

 

    Applied Materials, Inc.;

 

    ASML Holding, N.V.;

 

    KLA-Tencor Corp.;

 

    Lam Research Corp.; and

 

    Novellus Systems, Inc.

 

The forecasted financial information used by Citigroup for the selected comparable companies in the course of this analysis was based on projections published by Thomson First Call Research. Thomson First Call Research compiles summaries of financial forecasts published by various investment banking firms. The historical financial information used by Citigroup in the course of this analysis was based on publicly-available historical information. With respect to Mykrolis, Entegris and the comparable companies, calculations were made based on the closing price per share of each company’s common stock as of March 18, 2005, the last trading day before the announcement of the merger.

 

For each of the selected comparable companies, Mykrolis and Entegris, Citigroup derived and compared among other things:

 

    the ratio of the company’s firm value as of March 18, 2005, to its estimated revenues for the calendar years 2005 and 2006; and

 

    the ratio of the company’s stock price as of March 18, 2005, to its estimated earnings per share (EPS) for the calendar years 2005 and 2006.

Based on this analysis, Citigroup applied a range of multiples of 1.5x to 2.5x and 1.2x to 2.2x to estimated revenue for calendar years 2005 and 2006 respectively and a range of 19.0x to 28.0x and 15.0x to 22.0x to estimated earnings per share for calendar years 2005 and 2006 respectively to each of Mykrolis and Entegris to derive a range of firm values for each of Mykrolis and Entegris. Using the results of these calculations, Citigroup derived a reference range for the implied Equity Value of a share of Mykrolis common stock of $12.00 to $18.00 and a reference range for the implied Equity Value of a share of Entegris common stock of $8.00 to $13.00. Citigroup further derived a range for the implied exchange ratio of 1.35x to 1.82x. Citigroup noted that the exchange ratio in the merger of 1.39x was within this derived range.

 

Citigroup’s advisory services and opinion were provided for the information of the Mykrolis board of directors in its evaluation of the merger and did not constitute a recommendation of the merger to Mykrolis or a recommendation to any holder of Mykrolis common stock as to how that stockholder should vote on any matters relating to the merger.

 

The preceding discussion is a summary of the material financial analyses furnished by Citigroup to the Mykrolis board of directors, but it does not purport to be a complete description of the analyses performed by Citigroup or of its presentation to the Mykrolis board of directors. The preparation of financial analyses and fairness opinions is a complex process involving subjective judgments and is not necessarily susceptible to partial analysis or summary description. Citigroup made no attempt to assign specific weights to particular analyses or factors considered, but rather made qualitative judgments as to the significance and relevance of all the analyses and factors considered and determined to give its fairness opinion as described above. Accordingly, Citigroup believes that its analyses, and the summary set forth above, must be considered as a whole, and that selecting portions of the analyses and of the factors considered by Citigroup, without considering all of the analyses and factors, could create a misleading or incomplete view of the processes underlying the analyses conducted by Citigroup and its opinion. With regard to the comparable companies analysis summarized above, Citigroup selected comparable public companies on the basis of various factors, including size and similarity of the line of business of the relevant entities; however, no company utilized in this analysis is identical to Mykrolis or Entegris. As a result, this analysis is not purely mathematical, but also takes into account differences in financial and operating characteristics of the subject companies and other factors that could affect the public trading value of the subject companies to which Mykrolis and Entegris are being compared.

 

In its analyses, Citigroup made numerous assumptions with respect to Mykrolis, Entegris, Entegris Delaware, industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Mykrolis and Entegris. Any estimates contained in Citigroup’s analyses

 

58


Table of Contents

are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by these analyses. Estimates of values of companies do not purport to be appraisals or necessarily to reflect the prices at which companies may actually be sold. Because these estimates are inherently subject to uncertainty, none of Mykrolis, Entegris, Entegris Delaware, the Mykrolis board of directors, the Entegris board of directors, Citigroup or any other person assumes responsibility if future results or actual values differ materially from the estimates.

 

Citigroup’s analyses were prepared solely as part of Citigroup’s analysis of the fairness of the exchange ratio payable in the merger and were provided to the Mykrolis board of directors in that connection. The opinion of Citigroup was only one of the factors taken into consideration by the Mykrolis board of directors in making its determination to approve the merger agreement and the merger. See “—Recommendation of Mykrolis’ Board of Directors; Mykrolis’ Reasons for the Merger” beginning on page [    ].

 

Citigroup is an internationally recognized investment banking firm engaged in, among other things, the valuation of businesses and their securities in connection with mergers and acquisitions, restructurings, leveraged buyouts, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. Mykrolis selected Citigroup to act as its financial advisor to the board of directors of Mykrolis in connection with the proposed merger on the basis of Citigroup’s international reputation and Citigroup’s familiarity with Mykrolis.

 

Pursuant to its engagement letter with Mykrolis, Citigroup is entitled to the following fees: (i) $2,000,000, which became payable upon the delivery of Citigroup’s fairness opinion, and (ii) $6,500,000, less all fees paid pursuant to the previous clause, in the event the merger is consummated. Mykrolis has also agreed to reimburse Citigroup for its reasonable travel and other expenses incurred in connection with its engagement, including the reasonable fees and expenses of its counsel, and to indemnify Citigroup against specific liabilities and expenses relating to or arising out of its engagement, including liabilities under the federal securities laws. Citigroup and its affiliates in the past have provided services to Mykrolis and Entegris unrelated to the proposed merger, for which services Citigroup and its affiliates have received compensation, including acting as lead manager in connection with Mykrolis’ initial public offering and acting as co-manager in connection with Entegris’ initial public offering. In the ordinary course of its business, Citigroup and its affiliates may actively trade or hold the securities of Mykrolis, Entegris and Entegris Delaware for its own account or for the account of its customers and, accordingly, may at any time hold a long or short position in such securities. In addition, Citigroup and its affiliates (including Citigroup Inc. and its affiliates) may maintain relationships with Mykrolis, Entegris, Entegris Delaware and their respective affiliates.

 

Interests of Certain Persons in the Merger

 

As described below, certain officers of each of Entegris and Mykrolis and certain members of the Entegris board and of the Mykrolis board may have interests in the merger that are in addition to their interests as Entegris stockholders or Mykrolis stockholders generally.

 

The Entegris board and the Mykrolis board were aware of these interests and considered them, among other matters, in approving the merger agreement and the merger.

 

Mykrolis Executive Officers

 

Mykrolis Executive Termination Agreements

 

In connection with the execution of the merger agreement, on or about March 21, 2005, Mykrolis entered into an Amended and Restated Executive Termination Agreement with each of Jean-Marc Pandraud, Bertrand Loy, Peter Walcott, Fred Faulkner, Gerry Mackay and Takashi Mizuno, each of whom was a party to an executive termination agreement in substantially the form of the Executive Termination (Change of Control) Agreement filed with the Securities and Exchange Commission by Mykrolis as Exhibit 10.1 to its Quarterly

 

59


Table of Contents

Report on Form 10-Q for the quarterly period ended September 27, 2003, and incorporated herein by reference. See the discussion of the Executive Termination (Change of Control) Agreement of Jieh Hwa Shyu below for a summary of these original agreements. The amended and restated agreements replace these executive termination agreements.

 

Mykrolis requested that these executives sign the amended and restated agreements to eliminate certain features of the executive termination agreements that otherwise would have been triggered in connection with merger agreement and the merger. Under the executive termination agreements, each executive had the unilateral right to receive the benefits payable under his agreement by giving notice within 180 days after a change of control of a voluntary termination of employment following such 180 day period. In addition, the executive termination agreements provided for immediate acceleration of vesting of stock options and the lapse of restrictions on restricted stock upon the execution of a merger agreement. As explained below, the amended and restated agreements eliminate these features, providing that the benefits of the agreements are available only upon certain “involuntary terminations” of employment, as defined in the amended and restated agreements, and limiting the circumstances under which acceleration of options and lapse of restrictions on restricted stock occur. In exchange, the executives received certain benefits described below. The amended and restated agreements also made other changes to the executive termination agreements, as described below.

 

The amended and restated agreements provide that following the occurrence of an impending change of control (defined as (1) the execution of a definitive agreement, (2) the initiation of a tender offer, or (3) such other event as may be specified by the Mykrolis board, in each case relating to a transaction that, if completed, would constitute a change of control), the executive’s salary and benefits cannot be reduced for up to two years following a change of control and the executive and his family are entitled to medical, dental and life insurance benefits for a two-year period beginning upon the earlier of 180 days after the change of control or the date the Mykrolis board determines in good faith that a change of control will not result from the impending change of control, even if he is terminated during such period. A change of control is deemed to have occurred under the amended and restated agreements, in relevant part, (i) when any person becomes the beneficial owner, directly or indirectly, of at least 15% of Mykrolis’ then-outstanding common stock, (ii) if those persons who served on the board of directors on the effective date of the agreement, or, subject to certain exceptions, who were elected or nominated thereafter by the board, cease to constitute a majority of the board of Mykrolis (a “board change”), or (iii) upon stockholder approval of an agreement for the merger or other acquisition of Mykrolis which contemplates that substantially all of Mykrolis’ assets or business will be owned by a person or group that did not own them as of the effective date of the agreement or which contemplates a board change. Consequently, the execution of the merger agreement by Mykrolis constitutes an impending change of control, and the approval of the merger by Mykrolis stockholders would constitute a change of control. The amended and restated agreements provide for each executive to waive any accelerated vesting of outstanding stock options and restricted stock awards that would otherwise occur upon consummation of the merger under the terms of Mykrolis’ 2001 Equity Incentive Plan and 2003 Employment Inducement and Acquisition Stock Option Plan. However, in the event of any involuntary termination of the executive’s employment prior to the expiration of the two-year period following Mykrolis stockholder approval of the merger or within the period from the date of execution of the merger agreement through the date that the Mykrolis board determines in good faith that a change of control will not result from the merger agreement, the executive will become immediately entitled to exercise all unvested stock options for a period of up to one year following such involuntary termination (or, if earlier, until the expiration date of the options), the executive’s restricted stock will become free of restrictions, and the executive will become entitled to a lump sum severance payment equal to twice his highest annual rate of target total cash compensation during the three years prior to involuntary termination. An “involuntary termination” for purposes of the amended and restated agreements means any discharge of the executive by Mykrolis or any successor to Mykrolis, any resignation by the executive requested by Mykrolis or a successor, or any resignation by the executive following certain adverse changes to the terms or conditions of the executive’s employment, in each case that occurs from the time of the impending change of control through the date that is two years following the change of control or through the date the Mykrolis board determines in good faith that a change of control will not result from the impending change of control. The amended and restated agreements further provide for an additional tax “gross-up” payment to the executive of an amount sufficient to satisfy, on an after-tax basis, any

 

60


Table of Contents

excise tax payable by such executive under Section 4999 of the Internal Revenue Code of 1986 as a result of any payments or benefits received by him (whether or not received pursuant to the amended and restated executive employment agreement). Lastly, the amended and restated agreements provide that if the merger is not consummated on or prior to December 31, 2005, the executive may elect to revert back to the terms of the executive termination agreement in effect for such executive prior to such amendment, as described below.

 

Mykrolis has also entered into an executive termination agreement with Peter Kirlin, who was not previously party to an executive termination agreement with Mykrolis, on substantially the same terms as the amended and restated agreements referred to above, except that Mr. Kirlin’s agreement provides for a lump sum severance payment in an amount equal to twice his annualized rate of compensation in effect immediately prior to the impending change of control, including base salary plus variable compensation.

 

In addition, Mr. Argov’s employment letter agreement dated as of March 21, 2005 states that the board of directors of Mykrolis has approved the negotiation of a customary employment agreement with Mr. Argov containing a three-year term and a two-year non-competition agreement. It further states that this anticipated employment agreement will include change of control provisions that provide for severance benefits and accelerated vesting of stock option and restricted stock awards in the event that Mr. Argov’s employment with Entegris Delaware is terminated within two years following a change of control. The severance benefit would be equal to two years base salary plus variable compensation at the highest level during the three years prior to termination.

 

On May 4, 2005, as contemplated by Mr. Argov’s employment letter agreement, Mykrolis entered into an employment agreement with Mr. Argov. Mr. Argov’s employment agreement contains a change of control provision. Mr. Argov was not previously party to an executive termination agreement. Under Mr. Argov’s employment agreement, if Mr. Argov’s employment is terminated other than for cause (as defined in the agreement), he terminates his own employment for good reason (as defined in the agreement) or the initial three-year term of the agreement or any one-year extension period expires and Mykrolis or its successor has previously given Mr. Argov notice that it elects not to extend the agreement, in each case within two years after a change of control, he will be entitled to the following. First, he will receive, in addition to all forms of compensation that he has accrued prior to his termination, a lump sum severance payment in an amount equal to twice his base salary, plus twice the greater of his target bonus in the year of his termination or the highest annual bonus paid during the three years prior to his termination. Second, as under the executive termination agreements discussed above, Mr. Argov and his family will be entitled to medical, dental and life insurance benefits for a two-year period following the date of his termination or, if earlier, until he becomes eligible for coverage under the medical, dental and life insurance plans of another employer. Third, the employment agreement also provides for immediate vesting of all outstanding unvested equity awards, with stock options exercisable for up to one year after termination (or, if earlier, until the date the options would have expired absent termination). Mr. Argov is also entitled to reimbursement for outplacement services up to $15,000 in the event his employment is terminated after a change of control as described above.

 

A change of control is deemed to have occurred under Mr. Argov’s employment agreement, in relevant part, (i) when any person or group acquires beneficial ownership of 30% or more of Mykrolis’ or a successor’s (including Entegris Delaware) common stock or of the combined voting power of Mykrolis’ or a successor’s voting stock entitled to vote generally in the election of directors, (ii) if those persons who served on the board of directors of Mykrolis on the effective date of the agreement and until the closing of the merger, or those persons who constitute the board of directors of Entegris Delaware after the closing of the merger, or persons elected or nominated by at least a two-thirds vote of members of either such board, cease to constitute a majority of the board of Mykrolis or a successor (as applicable), or (iii) upon the consummation of a reorganization, merger or consolidation involving Mykrolis or a successor, or a sale of all or substantially all of the assets of Mykrolis or a successor, subject to certain exceptions.

 

Mr. Argov’s employment agreement further provides for an additional tax gross-up payment to Mr. Argov of an amount sufficient to satisfy, on an after-tax basis, any excise tax payable by Mr. Argov under Section 4999

 

61


Table of Contents

of the Internal Revenue Code of 1986 as a result of any payments or benefits received by him (whether or not received pursuant to the employment agreement).

 

If a change of control occurred at this time and all of the executives party to the amended and restated agreements as well as Mr. Kirlin and Mr. Argov were involuntarily terminated immediately following the change of control and those persons (other than Mr. Argov) satisfied certain conditions relating to their remaining with Mykrolis and cooperating with the Mykrolis board after the impending change of control, an aggregate of approximately $5,847,608 in severance payments would be due under the foregoing amended and restated agreements (or, in the case of Mr. Kirlin, his executive termination agreement and, in the case of Mr. Argov, his employment agreement).

 

In addition, each such executive may be entitled to tax gross-up payments. Section 4999 of the Internal Revenue Code of 1986 imposes a 20% excise tax on, and Section 280G of the Internal Revenue Code of 1986 denies an employer-level deduction for, so-called “excess parachute payments,” defined generally to mean the excess of “payments in the nature of compensation” that are contingent on a change in the ownership or control of a corporation, or on a change in the ownership of a substantial portion of the corporation’s assets, over the affected employee’s “base amount” (generally, his or her average annual taxable compensation measured over a period of up to five years ending with the year preceding the year of the change of control). If the sum of all such payments in the case of any individual is less than three times the base amount, no excise tax or loss of deduction results. However, if the sum of all such payments equals or exceeds three times the affected individual’s base amount, all “excess parachute payments” (that is, in general, all such payments in excess of one times the base amount) are subject to the excise tax and are nondeductible. The vesting of stock options, restricted stock and certain other rights in connection with a change of control, including in connection with a termination following a change of control, may give rise to “payments in the nature of compensation.” Also, in general, payments that are made pursuant to an agreement entered into within one year prior to a change of control are rebuttably presumed to be contingent on the change of control. On the other hand, a showing that payments constitute reasonable compensation for services rendered following the change of control, and certain other exceptions, may have the effect of reducing amounts potentially subject to the adverse tax treatment described in Sections 280G and 4999 of the Internal Revenue Code of 1986. If the employment of any of the executives party to the amended and restated agreements, or of Mr. Kirlin or Mr. Argov, were to terminate following the merger in circumstances entitling such person to benefits under his agreement, amounts payable pursuant to that agreement, including any cash benefits, any accelerated vesting of equity-based awards, and the continuation of any other benefits, would be treated as contingent in whole or in part on the change of control and, if the aggregate of such amounts and any other amounts so treated were to equal or exceed three times the affected individual’s “base amount,” assuming no other bases for exemption, would give rise to “excess parachute payments” equal to the excess of those amounts over one times the affected individual’s base amount. Any affected individual who becomes subject to the excise tax also would be entitled to receive a tax gross-up payment (itself treated as an “excess parachute payment” and therefore subject to the Section 4999 tax, and nondeductible) which on an after-tax basis equals the excise tax due on the other payments.

 

As discussed below under the caption “New Employment Letter Agreements with Mykrolis Officers,” Mr. Faulkner will be entitled to receive the benefits provided under his amended and restated agreement at the conclusion of his temporary post-merger assignment with Entegris Delaware pursuant to his employment letter agreement.

 

As also discussed below under the caption “New Employment Letter Agreements with Mykrolis Officers,” employment letter agreements between Mykrolis and each of Messrs. Pandraud, Loy, Walcott, Mackay and Mizuno (but not Mr. Faulkner) provide that, upon completion of the merger, each executive will enter into a new change of control agreement with Entegris Delaware to replace the amended and restated agreement described above. Mr. Loy’s employment letter agreement provides that Mr. Loy will have the unilateral right to resign his employment with Entegris Delaware within 90 days after the first anniversary of the merger and have such resignation treated as an involuntary termination entitling him to the severance payments, potential tax gross-up payments and other benefits to be provided under his anticipated new change of control agreement. Mr. Argov’s

employment agreement contains a change of control arrangement, as discussed above and below under the caption “New Employment Letter Agreements with Mykrolis Officers.”

 

Mykrolis remains subject to one Executive Termination (Change of Control) Agreement, dated May 1, 2003, with Jieh Hwa Shyu. The original executive termination agreements between Mykrolis and each of Messrs. Pandraud, Loy, Walcott, Mackay, Mizuno and Faulkner contained terms that were substantially similar to Mr. Shyu’s executive termination agreement. In contrast to the amended and restated agreements, Mr. Shyu’s agreement does not provide for the executive to waive the accelerated vesting of outstanding stock options and restricted stock awards that will occur upon consummation of the merger. The agreement instead accelerates such vesting upon the occurrence of an impending change of control. Upon execution of the merger agreement, which constituted an impending change of control under Mr. Shyu’s agreement, the options to acquire 25,813 shares of Mykrolis common stock and the 13,000 shares of restricted Mykrolis common stock held by Mr. Shyu became vested, fully exercisable and (in the case of the restricted stock) free of restrictions. In addition, Mr. Shyu’s agreement provides that beginning on the date of an impending change of control until 180 days after the occurrence of a change of control, Mr. Shyu’s salary and benefits cannot be reduced. The agreement also provides that following an impending change of control, Mr. Shyu and his family are entitled to medical, dental and life insurance benefits for a two-year period beginning 180 days after the change of control, even if he is terminated during such period. As under the amended agreements, Mykrolis’ execution of the merger agreement on March 21, 2005, constitutes an impending change of control and approval of the merger by Mykrolis stockholders would constitute a change of control. In the event of any involuntary termination of Mr. Shyu’s employment prior to the expiration of the two-year period following approval of the merger by Mykrolis stockholders or a voluntary resignation of which he gives notice within 180 days after such stockholder approval (provided that he does not voluntarily terminate employment within such 180-day period), Mr. Shyu will become entitled to enhanced benefits under Mykrolis’ pension and retirement plans and, subject to Mr. Shyu satisfying conditions relating to his remaining in the employ of Mykrolis and cooperating with the Mykrolis board after the impending change of control, a lump sum severance payment equal to twice his highest annual rate of total cash compensation during the three years prior to involuntary termination. Mr. Shyu’s agreement also provides for certain tax gross-up payments in the event he is subject to the excise tax under Section 4999 of the Internal Revenue Code of 1986 because of certain amounts paid to him under the agreement. Finally, the agreement also provides Mr. Shyu with the right to put his stock back to Mykrolis following a change of control.

 

If Mr. Shyu is involuntarily terminated prior to the expiration of the two-year period following the date Mykrolis stockholders approve the merger or voluntarily resigns pursuant to a notice given within 180 days after such stockholder approval (provided that he does not voluntarily terminate employment within such 180-day period) and the other conditions described above are satisfied, an aggregate of approximately $529,502 in severance pay plus enhanced benefits payments would be due under the agreement. In addition, Mr. Shyu may be entitled to tax gross-up payments. Whether tax gross-up payments would be due depends on application of the principles relating to Sections 4999 and 280G of the Internal Revenue Code of 1986 discussed above in this section, except that Mr. Shyu’s tax gross-up payment would on an after-tax basis equal the excise tax due on only a portion of the payments and benefits granted to him under his executive termination agreement.

 

Existing Mykrolis Employment Agreements

 

Mykrolis is party to a letter agreement, dated May 20, 2004, with Peter Kirlin under which Mr. Kirlin is employed as vice president, business development of Mykrolis on an at-will basis at a salary of $230,000 per year. In addition to executive-level benefits, the agreement provides that Mr. Kirlin is eligible to participate in the Mykrolis Incentive Plan (bonus plan). In addition, Mr. Kirlin received an option grant of 60,000 shares (subject to four-year vesting) pursuant to the letter agreement, with an option exercise price of $16.35 per share. In the event Mr. Kirlin is terminated other than for cause in his first year of employment, Mykrolis will continue to pay Mr. Kirlin’s salary and continue to provide Mr. Kirlin and his family with healthcare benefits for one year from the date of his termination.

 

Mykrolis is party to a letter agreement, dated November 19, 2004, with C. William Zadel, its former chairman and chief executive officer, under which Mr. Zadel is employed on a part-time basis as C.E.O.

 

63


Table of Contents

Emeritus of Mykrolis through April 30, 2006, at a salary of $40,000 per year. The agreement provides that Mr. Zadel is eligible to participate in the Mykrolis Savings and Investment Plan. The agreement is terminable by Mr. Zadel at any time or by Mykrolis upon Mr. Zadel’s death, material breach of the agreement, willful misconduct, commission of a fraud against the company or conviction of a felony.

 

Mykrolis was party to an offer letter agreement, dated November 18, 2004, with Gideon Argov under which Mr. Argov was employed as chief executive officer of Mykrolis on an at-will basis at a salary of $450,000 per year. In addition to executive level benefits, the agreement provided that Mr. Argov was eligible to participate in the Mykrolis Incentive Plan (bonus plan) beginning in 2006. Pursuant to the agreement, Mr. Argov received a restricted stock award of 50,000 shares (subject to four-year vesting) and an option grant of 450,000 shares (which vest 25% on the first anniversary of the grant date and quarterly thereafter in twelve equal installments), with an option exercise price of $11.60 per share.

 

Mykrolis was also party to a separation agreement, dated as of November 21, 2004, with Mr. Argov which provided that if Mr. Argov was terminated by the company other than for cause (as defined in the agreement), death or disability, or if Mr. Argov resigned for good reason (as defined in the agreement), Mykrolis agreed to continue to pay Mr. Argov’s salary and provide Mr. Argov and his family with healthcare benefits for one year from the date of his termination or resignation, as applicable.

 

The employment agreement dated May 4, 2005 between Mykrolis and Mr. Argov provides that the terms and conditions of the offer letter agreement and the separation agreement referred to above are no longer effective as of the effective date of the employment agreement.

 

New Employment Letter Agreements with Mykrolis Officers

 

In connection with entering into the merger agreement, Mykrolis entered into a letter agreement dated as of March 21, 2005, with each of Messrs. Argov, Pandraud, Loy, Walcott, Faulkner, Mackay and Mizuno outlining the duties, title, salary and benefits to be made available to such executives by the combined company following the merger. Mr. Faulkner’s letter agreement provides that his employment with Entegris Delaware will be temporary and conclude upon completion of certain milestones to be established relating to the integration of Mykrolis and Entegris following the merger. All of the terms of each letter agreement are contingent upon, among other things, the consummation of the merger and the continued active employment of such executive officer with Mykrolis through the closing of the merger. Upon consummation of the merger, the letter agreements will be assumed by Entegris Delaware by operation of law. The letter agreements provide that the salaries to be paid by Entegris Delaware to each of these executives after the merger will be consistent with the salaries they currently receive from Mykrolis (except that Mr. Loy’s annual base salary would increase by $23,000) and provide for restricted stock awards to each of Messrs. Argov, Pandraud, Loy, Walcott, Mackay and Mizuno in the amount of 200,000, 150,000, 100,000, 100,000, 75,000 and 75,000 shares of Entegris Delaware common stock, respectively. These restricted stock awards will vest 37.5% on December 31, 2005, and an additional 5.21% on the last business day of each of the first 12 fiscal quarters of Entegris Delaware following the completion of the merger. The letter agreements also provide that the executives will be entitled to participate in Entegris Delaware’s management incentive plan, which is to be developed during the pre-merger integration planning process. In addition, the letter agreements provide for a planning bonus, payable upon consummation of the merger, equal to 30% of such executive’s pro rated annual base salary for the period from March 1, 2005, through the closing date of the merger and an integration project bonus equal to 30% of such executive’s annual base salary, payable upon completion of the integration milestones to be established in connection with the merger. If both the planning bonuses and the integration bonuses are paid (and assuming the closing of the merger occurs on July 31, 2005), Messrs. Argov, Pandraud, Loy, Walcott, Mackay and Mizuno would receive $191,250, $133,490, $103,713, $99,896, $87,272 and $85,955, respectively.

 

In lieu of a restricted stock award, Mr. Faulkner will also be entitled to receive a retention bonus equal to 26 weeks of base salary upon completion of the integration milestones referred to above. Mr. Loy’s letter agreement provides that he will be employed for a one-year period following the closing of the merger after which he will

 

64


Table of Contents

have 90 days to elect to resign and receive the severance and other benefits that would otherwise be provided to him in the event of an involuntary termination under his anticipated change of control agreement described below.

 

Each letter agreement other than Mr. Faulkner’s and Mr. Argov’s provides that upon consummation of the merger, such executive will be required to enter into a change of control agreement with Entegris Delaware to replace the amended and restated executive termination agreements referred to above, which will generally be consistent with the amended and restated agreements but will also provide for a two-year non-competition agreement by the executive. A “change of control” under such anticipated new change of control agreement will be defined to include the merger of Mykrolis with and into Entegris Delaware. Mr. Faulkner’s letter agreement provides that his amended and restated executive termination agreement will continue in effect after the merger and that he will be entitled to the benefits provided pursuant to that agreement upon the conclusion of his assignment with Entegris Delaware under his letter agreement.

 

Mr. Argov’s letter agreement states that the board of directors of Mykrolis has approved the negotiation of a customary employment agreement with Mr. Argov containing a three-year term and a two-year non-competition agreement. The letter agreement further states that Mykrolis expects such employment agreement to be finalized prior to the merger and that Entegris Delaware would assume the obligations of Mykrolis under the agreement. The anticipated employment agreement would include change of control provisions that provide for severance benefits and accelerated vesting of stock option and restricted stock awards in the event that Mr. Argov’s employment with Entegris Delaware is terminated within two years following a change of control. The severance benefit would be equal to two years base salary plus variable compensation at the highest level during the three years prior to termination.

 

On May 4, 2005, Mykrolis entered into the employment agreement with Mr. Argov contemplated by his letter agreement. The employment agreement provides that Mykrolis will employ Mr. Argov as chief executive officer for a term of three years, subject to automatic extension from year to year unless either party gives notice that the employment term shall not be extended. The employment contract continues Mr. Argov’s current salary of $450,000 through 2005 and provides for a salary of $600,000 commencing January 1, 2006 if the merger is consummated. In addition Mr. Argov will be eligible to participate in Mykrolis’ incentive bonus plan at a target bonus level of 75% of base salary, in other employee benefits offered by Mykrolis, including equity incentive plans, and in any supplemental retirement plan offered by Mykrolis. He will also be entitled to receive a financial planning allowance. In the event of the termination of Mr. Argov’s employment under certain circumstances, he will be entitled to severance benefits that vary depending on the circumstances of the termination, including the severance benefits to which he is entitled in the event of a termination following a change of control (as defined in the agreement) as described above under the caption “Mykrolis Executive Termination Agreements.” If Mr. Argov is terminated by Mykrolis or a successor other than for cause, if he terminates his own employment for good reason or if Mykrolis or its successor elects not to extend the agreement for any of the otherwise automatic one-year extension periods, he will receive, in addition to all forms of compensation that he has accrued prior to termination, (i) payment of base salary commencing with the first regular payday in the seventh month following the date of termination for two years following the date of termination (or through the day immediately preceding the third anniversary of the effective date of the agreement if termination occurs prior to the first anniversary of the effective date of the agreement); (ii) the greater of the target bonus or the highest bonus paid to Mr. Argov during the three years prior to termination; (iii) continuation of health, dental and group life insurance coverage through the date Mr. Argov continues to receive his base salary following termination or the date he becomes eligible for such coverage with a different employer; (iv) immediate vesting of all outstanding unvested equity awards; and (v) reimbursement of up to $15,000 in outplacement services. Mr. Argov agreed to non-competition and non-solicitation covenants with Mykrolis for a period of two years following the termination of his employment. The employment agreement may be assigned by Mykrolis to the surviving corporation of a merger with Mykrolis.

 

Mykrolis Stock-Based Rights

 

Upon completion of the merger, each outstanding Mykrolis stock option, whether vested or unvested, will be converted into an option to purchase a number of shares of Entegris Delaware common stock equal to the

 

65


Table of Contents

number of shares of Mykrolis common stock that would have been obtained before the merger upon the exercise of the option, multiplied by the exchange ratio, and the exercise price of the converted option will be equal to the exercise price per share of the option before the conversion, divided by the exchange ratio. The conversion of “incentive stock options” will be effected in a manner that is consistent with Section 424(a) of the Internal Revenue Code of 1986.

 

Under certain of Mykrolis’ stock-based plans, upon a change of control of Mykrolis, unvested stock options or other stock-based awards will become fully vested and exercisable. The consummation of the transactions contemplated by the merger agreement will constitute a change of control under these Mykrolis stock-based plans, and Entegris Delaware is assuming all vested and unvested options and other stock-based awards that are outstanding at the effective time of the merger. As discussed above, Messrs. Pandraud, Loy, Walcott, Faulkner, Mackay, Mizuno and Kirlin have waived any such accelerated vesting of their options or other stock-based awards in connection with the consummation of the merger. Mr. Argov has also waived such accelerated vesting of options and other stock-based awards that would otherwise occur upon consummation of the merger under the Mykrolis plans. There are no unvested stock options to acquire shares of Mykrolis common stock or shares of restricted Mykrolis common stock held by other executive officers or directors of Mykrolis that will become vested or free of restrictions as a result of the merger. In addition, in the event that the merger occurs and Messrs. Argov, Pandraud, Loy, Walcott, Faulkner, Mackay, Mizuno and Kirlin are involuntarily terminated within the two-year period following the merger (and based on outstanding options and restricted stock awards as of [                    ], 2005 and assuming the grant of the Entegris Delaware restricted stock awards provided for in the new employment letter agreements referred to above), an aggregate of 906,511 unvested stock options to acquire shares of Entegris Delaware’s common stock, with an average exercise price of $7.61 per share, would become fully vested and exercisable and an aggregate of 1,037,631 shares of restricted common stock of Entegris Delaware would become fully vested and free of restrictions. Alternatively, in the event that the merger does not occur and Messrs. Argov, Pandraud, Loy, Walcott, Faulkner, Mackay, Mizuno and Kirlin are involuntarily terminated within either the two-year period following Mykrolis stockholder approval of the merger or on or prior to the date the Mykrolis board determines in good faith that a change of control will not result from the merger agreement (and based on outstanding options and restricted stock awards as of [                    ], 2005), an aggregate of 652,166 unvested stock options to acquire shares of Mykrolis common stock, with an average exercise price of $10.58 per share, would become fully vested and exercisable and an aggregate of 242,900 shares of restricted common stock of Mykrolis would become fully vested and free of restrictions.

 

Effective April 25, 2005, Mykrolis’ directors were each granted an annual stock option grant covering 8,000 shares of Mykrolis common stock at the closing price on the New York Stock Exchange on the date of grant. In addition, effective May 5, 2005, Mykrolis entered into a letter agreement with Robert E. Caldwell that provides that he will not serve as a director of Entegris Delaware upon the closing of the merger. In recognition of his service to the Mykrolis board of directors, the directors granted Mr. Caldwell a discretionary stock option grant for 21,866 shares of Mykrolis common stock effective on the termination of his service as a director upon the effectiveness of the merger. This discretionary option grant vests immediately upon completion of the merger and will be exercisable at the per share closing price of Mykrolis common stock on the New York Stock Exchange on the last trading date prior to the effective date of the merger. The discretionary option grant will not take effect in the event that the merger does not occur or that Mr. Caldwell becomes a director of Entegris Delaware pursuant to the merger.

 

Entegris Executive Officers

 

Each of James Dauwalter, Stan Geyer, Michael Wright, John Villas and Gregory Graves, current executive officers of Entegris, are parties to an Executive Employment Agreement with Entegris, substantially in the form of the Executive Employment Agreement filed with the Securities and Exchange Commission by Entegris as Exhibit 10.16 to its Annual Report on Form 10-K for the fiscal year ended August 31, 2002, and incorporated herein by reference. The Executive Employment Agreements provide for certain payments and benefits to the executives if they are involuntarily terminated or there occur certain adverse changes to their employment following a change of control of Entegris. The merger, including the reincorporation merger, does not constitute

 

66


Table of Contents

a change of control under the Executive Employment Agreements and, therefore, the payment and other provisions thereof will not be triggered in connection with the merger. In addition, pursuant to the terms of the governing plans and agreements relating thereto, the merger will not cause the acceleration of any outstanding but unvested options to purchase Entegris common stock or of any outstanding restricted stock awards, including those held by the executive officers.

 

At the time of the approval of the merger agreement, the board of directors of Entegris had not authorized any new agreements or arrangements in connection with the merger with the executive officers of Entegris. The board did receive a presentation by Mercer Human Resource Consulting, the compensation consultant to the Mykrolis board of directors. In this presentation, Mercer discussed the expected compensation actions Mykrolis contemplated taking with respect to its executive officers in connection with the merger, together with possible comparable compensation actions Entegris might consider taking in connection with the merger with respect to those Entegris executive officers expected to continue their executive positions with Entegris Delaware (comprising all of the executive officers other than James Dauwalter and Stan Geyer) and possible compensation arrangements of Entegris Delaware with Messrs. Dauwalter and Geyer.

 

It was the expectation of the Entegris board of directors at the time of its approval of the merger agreement, and it is the current expectation of both Entegris and Mykrolis, that, upon consummation of the merger, Entegris’ current executive officers who will be employed by Entegris Delaware will enter into change of control agreements with Entegris Delaware to replace their existing executive termination agreements with Entegris, some or all of the terms of which would be substantially the same as the new change of control agreements to be executed by Entegris Delaware and individuals who are currently Mykrolis officers upon consummation of the merger, as described above under the caption “New Employment Letter Agreements with Mykrolis Officers.” In addition, Dr. Kenneth Jennings, a human resources consultant to Entegris who is expected to serve as an executive officer of Entegris Delaware following the merger, is also expected to enter into such a change of control agreement with Entegris Delaware. The current Entegris executive officers expected to enter into new change of control agreements with Entegris Delaware are Michael Wright, John Goodman, John Villas and Greg Graves. As stated above, a “change of control” under such anticipated new change of control agreements will be defined to include the merger of Mykrolis with and into Entegris Delaware. Assuming these new change of control agreements are executed, if a change of control of Entegris Delaware occurred and resulted in an involuntary termination of a person party thereto within two years (which would include a discharge of the person and any resignation by the person following certain adverse changes to the terms or conditions of the person’s employment), giving rise to payments under these change of control agreements, then (based upon current salary and bonus information for the current Entegris executive officers and expected salary and bonus information for Dr. Jennings) an aggregate of approximately $4,908,768 in severance payments would be due to such officers and Dr. Jennings under the agreements if all of these persons are involuntarily terminated within such two-year period. Such officers and Dr. Jennings may also be entitled to tax gross-up payments. Whether tax gross-up payments would be due depends on application of the principles relating to Sections 4999 and 280G of the Internal Revenue Code of 1986 discussed above under the caption “Mykrolis Executive Termination Agreements.”

 

It is also expected that upon consummation of the merger, these same current executive officers of Entegris and Dr. Jennings will enter into employment letter agreements with Entegris Delaware, some or all of the terms of which would be substantially the same as the employment letter agreements between Mykrolis and current Mykrolis officers described above under the caption “New Employment Letter Agreements with Mykrolis Officers.” It is anticipated that each such current Entegris executive officer and Dr. Jennings would receive a base salary at least equal to his current base salary (or expected base salary, in the case of Dr. Jennings) and the same level of potential bonus payments as the Mykrolis officers. If so, assuming these executive officers and Dr. Jennings are paid both the planning bonuses and the integration bonuses contemplated under the letter agreements (and assuming the closing of the merger occurs on July 31, 2005), these persons would receive bonus payments of approximately $521,557 in the aggregate. Further, it is also expected that restricted stock awards in an aggregate amount of 525,000 shares of Entegris Delaware common stock will be made to Entegris executive officers and Dr. Jennings pursuant to these anticipated employment letter agreements. However, as of this date, such agreements are not in effect.

 

67


Table of Contents

Beginning in April 2005, the compensation committee of the Entegris board of directors commenced a process to research, discuss and determine appropriate severance, retention, integration bonus and other compensation to be paid to Messrs. Dauwalter and Geyer, the two current Entegris executive officers that are not expected to be employed as executive officers by Entegris Delaware following the merger. The compensation committee has retained Hewitt Associates, LLC as its independent advisor to assist it in this process.

 

Indemnification; Directors and Officers Liability Insurance

 

The merger agreement provides that Entegris Delaware will provide certain indemnification and directors and officers liability insurance to its officers and directors and to current and former directors and officers of Entegris and Mykrolis, including indemnification and insurance for matters occurring at or before the effective time of the merger. See “The Merger Agreement—Officer and Director Indemnification and Insurance.”

 

Officer and Director Positions with Entegris Delaware

 

Certain directors and executive officers of each of Mykrolis and Entegris will serve as executive officers or directors of Entegris Delaware following the merger, except that no directors of Entegris will serve as executive officers of Entegris Delaware following the merger. For a discussion of the expected composition of the board of directors of Entegris Delaware and the identities of the individuals expected to serve as executive officers of Entegris Delaware following the merger, see “Board of Directors and Management of Entegris Delaware Following the Merger” beginning on page [    ].

 

Ownership of Common Stock

 

As of the record date for the Entegris stockholder meeting, directors and executive officers of Entegris beneficially owned and were entitled to vote, or shared the right to vote, [            ] shares of Entegris common stock, entitling them to exercise, or having the shared power to exercise, approximately [        ]% of the voting power of the Entegris common stock entitled to vote at the Entegris stockholder meeting.

 

As of the record date for the Mykrolis stockholder meeting, directors and executive officers of Mykrolis (excluding Mr. Zadel, who is not an executive officer of Mykrolis as of the record date) beneficially owned and were entitled to vote [            ] shares of Mykrolis common stock, entitling them to exercise less than 1% of the voting power of the Mykrolis common stock entitled to vote at the Mykrolis stockholder meeting.

 

Accounting Treatment

 

The merger will be accounted for as a business combination using the “purchase” method of accounting. Entegris will be the acquirer for financial accounting purposes.

 

Regulatory Matters

 

Under the HSR Act, Entegris and Mykrolis were required to give notification and furnish information to the Federal Trade Commission and the Antitrust Division of the U.S. Department of Justice and to wait until the expiration or termination of the specified waiting period before they can complete the merger. On April 7, 2005, Entegris and Mykrolis submitted the required regulatory filings to the Federal Trade Commission and the Antitrust Division. On April 21, 2005, the Federal Trade Commission granted early termination of the HSR waiting period. In addition, the merger is subject to state antitrust laws and could be the subject of challenges by state attorneys general under those laws, or by private parties under federal or state antitrust laws.

 

Neither Entegris nor Mykrolis is aware of any foreign governmental approvals or actions that are required for completion of the merger. Nonetheless, in connection with the merger, the laws of a number of foreign countries and jurisdictions in which Entegris and/or Mykrolis conducts their business may require the filing of information with, or the obtaining of the approval or consent of, governmental authorities in those countries and jurisdictions. The governments in those countries and jurisdictions might attempt to impose additional conditions

 

68


Table of Contents

on Entegris Delaware’s operations conducted in those countries and jurisdictions as a result of the merger. If those approvals or consents are found to be required, the parties intend to make the appropriate filings and applications. In the event that a filing or application is made for the requisite foreign approvals or consents, the parties cannot assure you when, if ever, those approvals or consents will be granted.

 

Dissenters’ Appraisal Rights of Entegris Stockholders

 

Entegris stockholders are not entitled to any dissenters’ appraisal rights in connection with the reincorporation merger or the merger under Minnesota law or, after they become stockholders of Entegris Delaware upon the reincorporation, under Delaware law. Under Minnesota law, dissenters’ appraisal rights are not available to stockholders of a Minnesota corporation with respect to a merger to which the Minnesota corporation is a party (the reincorporation merger) if its shares are either listed on a national securities exchange or The NASDAQ National Market and such stockholders are required to receive only shares of the surviving corporation or shares of any other corporation which are listed on a national securities exchange or The NASDAQ National Market, cash in lieu of fractional shares, or a combination of the foregoing. The Entegris stockholders are not entitled to appraisal rights in connection with the merger because they will not be stockholders of Entegris Delaware on the record date for the special meeting of Entegris Delaware stockholders relating to the merger.

 

Dissenters’ Appraisal Rights of Mykrolis Stockholders

 

Under Delaware law, dissenters’ appraisal rights are not available with respect to a merger or consolidation by a corporation the shares of which are either listed on a national securities exchange or The NASDAQ National Market or held of record by more than 2,000 stockholders if such stockholders are required to receive only shares of the surviving corporation or shares of any other corporation which are either listed on a national securities exchange or The NASDAQ National Market or held of record by more than 2,000 holders, cash in lieu of fractional shares, or a combination of the foregoing. Therefore, stockholders of Mykrolis will not be able to exercise any dissenters’ appraisal rights in connection with the merger.

 

Delisting and Deregistration of Mykrolis Common Stock

 

If the merger is completed, Mykrolis common stock will be delisted from the New York Stock Exchange and will be deregistered under the Securities Exchange Act of 1934. The stockholders of Mykrolis will become stockholders of Entegris Delaware and their rights as stockholders will be governed by applicable Delaware law and by Entegris Delaware’s certificate of incorporation and bylaws. See “Comparison of Rights of Stockholders” beginning on page[    ].

 

Federal Securities Laws Consequences; Resale Restrictions

 

All shares of Entegris Delaware common stock that will be distributed to Mykrolis stockholders in the merger will be freely transferable, except for restrictions applicable to “affiliates” of Mykrolis and except that the resale restrictions may be imposed by securities laws in non-U.S. jurisdictions insofar as subsequent trades are made within these jurisdictions. Persons who are deemed to be affiliates of Mykrolis may resell Entegris Delaware common stock received by them only in transactions permitted by the resale provisions of Rule 145 under the Securities Act of 1933 or as otherwise permitted under the Securities Act of 1933. Persons who may be deemed to be affiliates of Mykrolis generally include executive officers, directors and holders of more than 10% of the outstanding shares of Mykrolis. The merger agreement requires Mykrolis to cause each of its directors and executive officers who Mykrolis believes may be deemed to be affiliates of Mykrolis to execute a written agreement to the effect that those persons will not sell, assign or transfer any of the shares of Entegris Delaware common stock issued to them in the merger unless that sale, assignment or transfer has been registered under the Securities Act of 1933, is in conformity with Rule 145 or is otherwise exempt from the registration requirements under the Securities Act of 1933.

 

This joint proxy statement/prospectus does not cover any resales of the shares of Entegris Delaware common stock to be received by Mykrolis stockholders in the merger, and no person is authorized to make any use of this joint proxy statement/prospectus in connection with any resale.

Fiscal Year of Entegris Delaware

 

We expect that Entegris Delaware will, at or before the effective time of the reincorporation merger, adopt a fiscal year that ends on December 31. This would result in Entegris Delaware finishing fiscal year 2005 in August 2005 pursuant to Entegris’ fiscal calendar, operating under an interim “transition” period thereafter until December 31, 2005 and then starting a calendar fiscal year in January 2006.

 

The Reincorporation Proposal

 

At Entegris’ special meeting, Entegris’ stockholders will be asked to consider and vote upon a proposal to approve and adopt the reincorporation merger agreement attached hereto as Annex B and the reincorporation merger contemplated by that agreement whereby Entegris would reincorporate from a Minnesota corporation to a Delaware corporation, including approval of the proposed certificate of incorporation and bylaws of Entegris Delaware attached as Annex C-1 and Annex D hereto, respectively, provided that if the classified board proposal (proposal 3 to be presented at the Entegris stockholder meeting) is not approved, the certificate of incorporation of Entegris Delaware would read as set forth on Annex C-2 hereto and the bylaws of Entegris Delaware set forth on Annex D would be revised by the Entegris Delaware board to remove the classified board provisions and to include provisions substantially similar to Article IX set forth in Annex C-2.

 

The reincorporation would be effected by merging Entegris with and into its wholly owned subsidiary, Eagle DE, Inc., a Delaware corporation and referred to herein as Entegris Delaware, with Entegris Delaware being the surviving corporation and renamed Entegris, Inc. Entegris Delaware was incorporated in Delaware in March 2005 specifically for purposes of the reincorporation and has conducted no business and has no material assets or liabilities, in each case other than as related to the merger agreement and the reincorporation merger agreement.

 

On the effective date of the reincorporation, Entegris Delaware will succeed to all of the assets, liabilities and business of Entegris and will possess all of the rights and powers of Entegris. Immediately following the reincorporation, Mykrolis will merge with and into Entegris Delaware pursuant to the merger agreement.

 

Reasons for the Reincorporation

 

During the negotiation of the merger agreement, Mykrolis asked Entegris to agree to reincorporate in Delaware and that the reincorporation be made a condition to completion of the merger. Mykrolis is a Delaware corporation and desires that the combined company be a Delaware corporation. As part of the negotiations, the Entegris board of directors agreed to Mykrolis’ request. As a result, the merger agreement provides that completion of the merger is conditioned on approval by Entegris stockholders of the reincorporation proposal and completion of the reincorporation.

 

Many major corporations have chosen Delaware for their domicile or have subsequently reincorporated in Delaware. Because of Delaware’s significance as the state of incorporation for many major corporations, the Delaware judiciary has become particularly familiar with matters of corporate law, and a substantial body of court decisions has developed construing Delaware’s corporation laws. Consequently, Delaware corporate law has been, and is likely to continue to be, interpreted and explained in a number of significant court decisions, a circumstance which may provide greater predictability with respect to the combined company’s legal affairs.

 

The merger agreement provides that the reincorporation will not be effected unless all conditions of the merger have been satisfied or waived, and Entegris Delaware and Mykrolis are prepared to consummate the merger immediately after the effective time of the reincorporation merger.

 

Certain Consequences of the Reincorporation

 

At the effective time of the reincorporation merger, the separate corporate existence of Entegris will cease, and stockholders of Entegris, which is a Minnesota corporation, will become stockholders of Entegris Delaware. Entegris Delaware will continue to operate Entegris’ business under the name Entegris, Inc. and, upon completion of the merger, will operate the combined company’s business.

The rights of Entegris Delaware stockholders will be governed by Delaware law and Entegris Delaware’s certificate of incorporation and bylaws. For a description of those rights and how they differ from the rights of Entegris stockholders under Minnesota law and Entegris’ current articles of incorporation and bylaws, see “Comparison of Rights of Stockholders” beginning on page [    ]. To obtain a copy of Entegris’ current articles of incorporation and bylaws, please refer to Exhibits 3.3 and 3.4 of the Form S-4 registration statement of which this joint proxy statement/prospectus is a part and which has been filed with the Securities and Exchange Commission. See “Where You Can Find More Information” beginning on page [    ].

 

If the proposal relating to a classified board is approved by Entegris stockholders, Entegris Delaware will have a classified board of directors. For a description of the classified board proposal and the effects a classified board will have on Entegris Delaware and its stockholders, see “The Classified Board Proposal” beginning on page [    ] and “Comparison of Rights of Stockholders” beginning on page [    ].

 

As a result of the reincorporation, (i) each outstanding share of Entegris common stock will automatically be converted without any action by the holder into one share of common stock of Entegris Delaware and (ii) each outstanding option to purchase shares of Entegris common stock and each restricted stock unit that may be surrendered for Entegris common stock that has been granted under any employee stock option or compensation plan of, or other arrangement with, Entegris shall become an option or restricted stock unit, as the case may be, for the same number of shares of Entegris Delaware common stock for which, immediately prior to the effective time of the reincorporation merger, it was exercisable or could be surrendered, subject to the same vesting schedule, forfeiture provisions and exercise price, as applicable, in effect immediately before the effective time of the reincorporation merger. Restricted stock of Entegris that is converted into restricted stock of Entegris Delaware as a result of the reincorporation merger shall be subject to the same vesting schedule and forfeiture provisions, as applicable, in effect immediately before the effective time of the reincorporation merger.

 

Upon consummation of the reincorporation, certificates representing shares of Entegris common stock will be deemed to represent the same number of shares of Entegris Delaware common stock as reflected on such certificates immediately before the reincorporation.

 

Entegris common stock is listed for trading on The NASDAQ National Market. We intend to apply to have the Entegris Delaware common stock listed for trading on The NASDAQ National Market effective as of the time of the completion of the reincorporation under the same symbol, “ENTG,” as the shares of Entegris common stock are currently traded. The listing of Entegris Delaware common stock on The NASDAQ National Market is a condition to the completion of both the reincorporation merger and the merger.

 

The consummation of the reincorporation is conditioned on approval of the merger, and consummation of the merger is conditioned on completion of the reincorporation. In addition, if the merger is not going to be consummated for any reason, the reincorporation will not be effected, even if Entegris stockholders have approved both the merger and the reincorporation.

 

The Entegris board of directors unanimously recommends that Entegris stockholders vote “FOR” the reincorporation proposal.

 

The Classified Board Proposal

 

Proposal 3 to be presented at the Entegris special meeting asks Entegris stockholders to approve a classified board for Entegris Delaware as provided in Article IX of the proposed certificate of incorporation of Entegris Delaware attached as Annex C-1 to this joint proxy statement/prospectus (the “classified board article”). The classified board article (i) provides for a board of directors divided into three classes of directors serving staggered three–year terms, (ii) prohibits the removal of directors for reasons other than cause, and (iii) requires the affirmative vote of the holders of at least 75% of the outstanding shares of capital stock of Entegris Delaware entitled to vote generally in the election of directors to remove a director with cause or to amend or repeal, or adopt any provisions inconsistent with the purpose or intent of, the classified board article.

 

71


Table of Contents

Under the classified board article, approximately one–third of the board of directors of Entegris Delaware would be elected each year starting with the first annual meeting of Entegris Delaware. Pursuant to the merger agreement, the Entegris Delaware board of directors will initially consist of ten directors, with an eleventh director expected to be named shortly after the merger is completed. See “Board of Directors and Management of Entegris Delaware Following the Merger.” As explained in “Board of Directors and Management of Entegris Delaware Following the Merger,” the three directors constituting the Class I directors would serve for a one–year term expiring at the first annual meeting; the four directors constituting the Class II directors would serve for a two–year term expiring at the second annual meeting; and the three directors constituting the Class III directors would serve for a three-year term expiring at the third annual meeting. If an eleventh director is appointed as expected, the nominating and governance committee of the Entegris Delaware board will recommend to the board of directors the class to which such eleventh director should be assigned. At each annual meeting starting with the first annual meeting, directors would be elected to succeed those whose terms expire, with each newly elected director to serve for a three-year term.

 

The foregoing description of the classified board article is not intended to be complete and is qualified in its entirety by reference to the complete text of the classified board article.

 

Reasons for and Effects of the Classified Board Proposal

 

Mykrolis currently has a classified board under provisions of its certificate of incorporation and bylaws which are substantially similar to the classified board article, and Mykrolis desires to retain such provisions of its corporate governance structure in the combined company. As part of the negotiation of the merger agreement, Entegris agreed to include the classified board article in the Entegris Delaware certificate of incorporation and bylaws, subject to the approval of its stockholders, if required, so long as approval of the proposal by the Entegris stockholders was not made a condition to the completion of the merger. As a result, the merger agreement provides that neither the merger nor the reincorporation merger is conditioned on the approval by Entegris stockholders of the classified board proposal. The classified board proposal, however, is conditioned on the consummation of the merger and the reincorporation merger. If the classified board proposal is not approved and the merger occurs, Entegris Delaware’s certificate of incorporation will read as set forth in Annex C-2 to this joint proxy statement/prospectus and the bylaws of Entegris Delaware set forth in Annex D will be amended by Entegris Delaware’s board to remove the classified board provisions and to include provisions substantially similar to Article IX of Annex C-2.

 

The boards of directors of Entegris and Mykrolis believe that the classified board article may be advantageous to Entegris Delaware for several reasons. First, the classified board article may enhance continuity and stability in the policies formulated by the Entegris Delaware board because directors would serve three-year rather than one-year terms. Establishing three-year terms may also increase Entegris Delaware’s ability to attract and retain desirable directors. In addition, a classified board may decrease the likelihood that a proposal to acquire Entegris Delaware would succeed that the then existing board of Entegris Delaware believed would prevent stockholders of Entegris Delaware from receiving the full value of their investments.

 

The classified board proposal, however, may discourage individuals or entities from purchasing shares of Entegris Delaware’s common stock in order to obtain actual control of Entegris Delaware by electing their own slate of directors or to achieve some other goal, such as the repurchase of their shares at a premium or a restructuring of Entegris Delaware, by threatening to obtain such control. It may have such effect because the provisions of the classified board article could delay the purchaser’s ability to obtain control of the Entegris Delaware board in a relatively short period of time. The delay may arise because under the classified board proposal, it will generally take a purchaser (or any other individual or entity) two annual meetings (as contrasted with a single meeting under the certificate of incorporation and bylaws of Entegris Delaware that will be in effect if the classified board proposal is not approved) to elect a majority of the board unless directors have been removed from office during their terms, regardless of whether such purchaser acquires a majority of the common stock. Further, removal without cause of a director whose term has not expired would be prohibited, and removal

 

72


Table of Contents

with cause would require the affirmative vote of holders of at least 75% of the shares of capital stock of Entegris Delaware issued and outstanding and entitled to vote generally in the election of directors.

 

For the same reasons, the adoption of the classified board proposal may also deter certain mergers, tender offers, proxy contests or other future takeover attempts which holders of some or a majority of the common stock of Entegris Delaware may deem to be in their best interests. The classified board proposal would delay stockholders who are not in agreement with the policies of the Entegris Delaware board of directors or who desire that Entegris Delaware effect a merger or other business combination, including a merger with a substantial stockholder, from electing or removing a majority of the board for two years unless they could attain the requisite 75% vote and cause for removal of a majority of the board existed. The classified board proposal applies to every election of directors, whether or not a change in substantial ownership of Entegris Delaware is contemplated or shall have occurred. The combination of increasing the terms of directors to three years, prohibiting removal for reasons other than cause, and increasing the percentage voting requirement necessary to remove directors for cause may render more difficult the removal for up to three years of any individual director that management, a majority of the board of directors or a majority of the stockholders believe should be removed, whether or not a change of substantial ownership of Entegris Delaware is contemplated or shall have occurred.

 

The boards of each of Entegris and Mykrolis have no knowledge of any present effort to change the expected composition of the Entegris Delaware board of directors as of the time of the merger, to gain control of Entegris Delaware after the merger, or to organize a proxy contest with respect to Entegris Delaware. Moreover, there has been no problem in the past or at the present time with board continuity or stability at Entegris or Mykrolis.

 

Neither the board of directors of Mykrolis nor the board of directors of Entegris presently has any reason to believe that the Entegris Delaware board will adopt, or recommend to the stockholders of Entegris Delaware for their adoption, any further amendments to Entegris Delaware’s certificate of incorporation or bylaws following the adoption of the certificate of incorporation set forth in Annex C-1 and the bylaws set forth in Annex D that would affect the ability of third parties to take over or change control of Entegris Delaware. For a description of the stockholder rights plan expected to be adopted by Entegris Delaware and its possible anti-takeover effects and a description of possible anti-takeover effects of provisions of Delaware law and the certificate of incorporation and bylaws of Entegris Delaware set forth as Annexes to this joint proxy statement/prospectus other than the classified board proposal, see “Description of Entegris Delaware’s Capital Stock—Stockholder Rights Plan; —Anti-Takeover Effects of Provisions of Entegris Delaware’s Certificate of Incorporation, Bylaws, Stockholder Rights Plan and Delaware Law” beginning on page [    ].

 

The Entegris board of directors unanimously recommends that Entegris stockholders vote “FOR” the classified board proposal.

 

Non-Disclosure Agreements

 

In connection with their entering into discussions relating to the proposed merger, each of Entegris and Mykrolis executed a non-disclosure agreement in favor of the other party dated as of January 21, 2005. In the agreements, each party agreed to keep confidential their discussions concerning the proposed merger absent consent of the other party to disclosure of such discussions. The agreements also require each party to keep confidential all non-public information provided to it by the other party and not to use any such non-public information for any purpose other than evaluating the proposed transaction. Each party further agreed that for a period of two years from the date of the agreement, it would not, without the consent of the other party’s board of directors, engage in or attempt to engage in certain transactions relating to obtaining securities, assets or control of the other party, enter into discussions, negotiations, understandings or arrangements with third parties relating to any such transactions, or disclose any intention, plan or arrangement inconsistent with these prohibitions. The agreements also prohibit each party from hiring or soliciting (with certain exceptions) “senior employees” (as that term is defined in the agreements) of the other for 18 months from the date of the agreements.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

 

Material U.S. Federal Income Tax Consequences

 

The discussion below summarizes the material United States federal income tax consequences of the reincorporation merger and the merger (together, the “mergers”) that are generally applicable to common stockholders of Entegris and Mykrolis who are “United States persons,” as defined for United States federal income tax purposes, and who hold their common stock in Entegris or Mykrolis, as applicable, as a capital asset. For United States federal income tax purposes, a “United States person” is:

 

    a United States citizen or resident alien as determined under the Internal Revenue Code of 1986;

 

    a corporation (as defined by the Internal Revenue Code of 1986) that is organized under the laws of the United States, any state or the District of Columbia;

 

    an estate, the income of which is subject to United States federal income taxation regardless of its source; or

 

    a trust, if a court within the United States is able to exercise primary supervision over its administration and at least one United States person is authorized to control all of its substantial decisions.

 

If a partnership (including any entity treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of shares of Entegris or Mykrolis common stock, the tax treatment of a partner in that partnership will generally depend on the status of the partner and the activities of the partnership. Holders of shares of Entegris or Mykrolis common stock that are partnerships and partners in these partnerships are urged to consult their tax advisors regarding the U.S. federal income tax consequences of owning and disposing of shares of Entegris or Mykrolis common stock in the reincorporation merger or the merger.

 

The discussion below is based on current provisions of the Internal Revenue Code of 1986, currently applicable United States Treasury regulations promulgated thereunder, and judicial and administrative decisions and rulings.

 

No ruling from the Internal Revenue Service has been or will be sought. Future legislative, judicial or administrative changes or interpretations could alter or modify the statements and conclusions set forth herein, and such changes or interpretations could be retroactive and could affect the tax consequences of the mergers to Entegris, Mykrolis and their stockholders.

 

The discussion below does not purport to deal with all aspects of federal income taxation that may affect particular stockholders in light of their individual circumstances or that may affect stockholders subject to special treatment under federal income tax law. Stockholders subject to special treatment include insurance companies, tax-exempt organizations, financial institutions, broker-dealers, foreign individuals and entities, stockholders who hold their stock as part of a hedge, wash sale, appreciated financial position, straddle, conversion or other risk reduction transaction, and stockholders who have acquired their stock upon exercise of employee options or otherwise as compensation. In addition, the discussion below does not consider the effect of any applicable state, local or foreign tax laws.

 

You are urged to consult with your tax advisor as to the tax consequences of the mergers to you in light of your particular circumstances, including the applicability and effect of any state, local or foreign tax laws.

 

It is anticipated that Faegre & Benson LLP, counsel to Entegris, will deliver an opinion to Entegris, effective on or about the date the Form S-4 registration statement of which this joint proxy statement/prospectus is a part is declared effective by the Securities and Exchange Commission, to the effect that each of the reincorporation merger and the merger will be treated as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986. It is anticipated that Ropes & Gray LLP, counsel to Mykrolis, will deliver

 

74


Table of Contents

an opinion to Mykrolis, effective on or about the date the Form S-4 registration statement of which this joint proxy statement/prospectus is a part is declared effective by the Securities and Exchange Commission, to the effect that the merger will be treated as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986. It is a condition to the closing of the mergers that similar opinions be given by Faegre & Benson LLP and Ropes & Gray LLP to Entegris and Mykrolis, respectively, effective as of the closing date of the merger. Such opinions will be based on certificates executed by officers of Entegris and Mykrolis containing representations regarding past, current and future matters that are customary for transactions of this nature. If any of the representations is inaccurate or incorrect, the conclusions stated in the opinions could be affected. The opinions will not be binding on the Internal Revenue Service or the courts, and there can be no assurance that the Internal Revenue Service or the courts will not take a contrary view.

 

The following are the material United States federal income tax consequences that will generally result to Entegris, Entegris Delaware, Mykrolis, holders of Entegris common stock and holders of Mykrolis common stock if the mergers are treated as reorganizations described in Section 368(a) of the Internal Revenue Code of 1986:

 

    A holder of Entegris common stock will not recognize any gain or loss upon the receipt of Entegris Delaware stock in exchange for Entegris common stock in the reincorporation merger.

 

    An Entegris stockholder’s aggregate tax basis in the Entegris Delaware common stock received in the reincorporation merger in exchange for such stockholder’s Entegris common stock will be the same as the aggregate basis of the Entegris common stock surrendered in the exchange.

 

    An Entegris stockholder’s holding period for the Entegris Delaware common stock received in the reincorporation merger in exchange for such stockholder’s Entegris common stock will include the holding period for the Entegris common stock surrendered in the exchange.

 

    A holder of Mykrolis common stock will not recognize any gain or loss upon the receipt of Entegris Delaware common stock in exchange for Mykrolis common stock in the merger, except to the extent of cash received in lieu of fractional shares.

 

    Cash received by a holder of Mykrolis common stock in lieu of a fractional share will generally be treated as received in exchange for such fractional share and will result in capital gain (or loss) to such holder measured by the difference between the cash payment received and the portion of the tax basis in the shares of Mykrolis common stock surrendered that is allocable to the fractional share. Any such gain (or loss) will generally be long-term capital gain (or loss) if the Mykrolis common stock has been held for more than one year at the effective time of the merger.

 

    A Mykrolis stockholder’s aggregate tax basis in the Entegris Delaware common stock received in the merger in exchange for such stockholder’s Mykrolis common stock will be the same as the aggregate basis of the Mykrolis common stock surrendered in the exchange, reduced by any amount of tax basis allocable to a fractional share of Mykrolis common stock for which cash is received.

 

    A Mykrolis stockholder’s holding period for the Entegris Delaware common stock received in the merger in exchange for such stockholder’s Mykrolis common stock will include the holding period for the Mykrolis common stock surrendered in the exchange.

 

    None of Entegris, Entegris Delaware or Mykrolis will recognize any gain or loss as a result of the merger or the reincorporation merger.

 

If the Internal Revenue Service were to successfully challenge the “reorganization” status of the reincorporation merger or the merger, a holder of Entegris common stock (in the case of a successful challenge of the “reorganization” status of the reincorporation merger) or Mykrolis common stock (in the case of a successful challenge of the “reorganization” status of the merger) would recognize gain or loss with respect to such stockholder’s shares of common stock surrendered in the reincorporation merger or merger, as applicable. The gain or loss would be equal to the difference between (i) the fair market value of the Entegris Delaware

 

75


Table of Contents

common stock received in the reincorporation merger or merger, as applicable, and (ii) the stockholder’s adjusted tax basis in the Entegris common stock surrendered in the reincorporation merger or the holder’s adjusted tax basis in the Mykrolis common stock surrendered in the merger, as applicable. Such stockholder’s total tax basis in the Entegris Delaware common stock received would equal its fair market value and such stockholder’s holding period for the stock would begin the day after the reincorporation merger or merger, as applicable.

 

Each Mykrolis stockholder who receives shares of Entegris Delaware common stock in the merger is required to file a statement with his, her or its federal income tax return setting forth the stockholder’s basis in the shares of Mykrolis common stock surrendered, the fair market value of Entegris Delaware common shares received in the merger, and the proceeds from the cash in lieu of fractional shares received in the merger, and is required to retain permanent records of these facts. Each Entegris stockholder who receives shares of Entegris Delaware common stock in the reincorporation merger is required to retain permanent records of the stockholder’s basis in the shares of Entegris common stock surrendered and the fair market value of the Entegris Delaware common shares received in the reincorporation merger.

 

Backup withholding at 28% may apply with respect to certain payments, including cash received for fractional shares, unless a Mykrolis stockholder (1) is a corporation or comes within certain other exempt categories and, when required, demonstrates this fact or (2) provides a correct taxpayer identification number, certifies as to no loss of exemption from backup withholding and that such stockholder is a United States person (including a United States resident alien) and otherwise complies with applicable requirements of the backup withholding rules. A Mykrolis stockholder who does not provide Entegris (or the exchange agent) with its correct taxpayer identification number may be subject to penalties imposed by the Internal Revenue Service. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against the stockholder’s United States federal income tax liability, provided that the stockholder furnishes certain information to the Internal Revenue Service.

THE MERGER AGREEMENT

 

General

 

The following summary of the merger agreement is qualified in its entirety by reference to the complete text of the merger agreement, which is attached as Annex A to this joint proxy statement/prospectus and incorporated by reference herein. We urge you to read carefully this entire document, including the annexes and other documents to which we have referred you. See “Where You Can Find More Information” beginning on page [    ].

 

The Reincorporation Merger; The Merger; Filing of Certificate of Merger

 

Prior to the consummation of the merger, Entegris will first effect a reincorporation from a Minnesota corporation to a Delaware corporation through a merger of Entegris with and into Entegris Delaware, a direct wholly owned subsidiary of Entegris. The reincorporation merger will be effected pursuant to the reincorporation merger agreement between Entegris and Entegris Delaware, which is attached as Annex B to this joint proxy statement/prospectus. All references in this joint proxy statement/prospectus to the reincorporation merger agreement are qualified in their entirety by reference to the complete text of the reincorporation merger agreement. As a result of the reincorporation merger of Entegris with and into Entegris Delaware, Entegris will cease to exist and Entegris Delaware will continue as the surviving corporation of the reincorporation merger.

 

Entegris, Entegris Delaware and Mykrolis have agreed that the reincorporation merger is being consummated only to facilitate the completion of the merger. The reincorporation merger will not occur unless all conditions to the merger have been satisfied or waived and Entegris Delaware and Mykrolis are prepared to complete the merger immediately after the effective time of the reincorporation merger.

 

Immediately following the reincorporation merger and subject to the terms and conditions of the merger agreement, Mykrolis will merge with and into Entegris Delaware, which will be the surviving corporation in the merger. The combined company will be a Delaware corporation named Entegris, Inc. As a result of the merger of Mykrolis with and into Entegris Delaware, Mykrolis will cease to exist and Entegris Delaware (thereafter known as Entegris, Inc.) will continue as a public company that holds and conducts the combined business of Mykrolis and Entegris and their subsidiaries.

 

The certificate of merger relating to the merger will be filed immediately following the effective time of the reincorporation merger and as soon as practicable, but no more than three business days following the later of the receipt of the necessary approval of the stockholders of Entegris and Mykrolis and the date on which all of the conditions to the merger have been satisfied or waived (other than the conditions relating to the provision by the parties of officer’s certificates as to the accuracy of such party’s representations and warranties, the performance of such party’s obligations, and the lack of a material adverse change relating to such party and relating to the delivery of legal opinions relating to the tax treatment of the merger, so long as these conditions are satisfied or waived at the closing), unless the parties agree on another date.

 

The effective time of the merger will be the time Entegris Delaware and Mykrolis file the certificate of merger or at such later date or time as Entegris Delaware and Mykrolis agree and specify in the certificate of merger.

 

Merger Consideration

 

At the effective time of the reincorporation merger, each issued and outstanding share of Entegris common stock will be automatically converted, without further action by any Entegris stockholder, into one fully paid and nonassessable share of Entegris Delaware common stock, and each share of Entegris Delaware common stock owned by Entegris immediately prior to the effective time of the reincorporation merger will be canceled.

 

77


Table of Contents

At the effective time of the merger, each issued and outstanding share of Mykrolis common stock (other than any such common stock held by Entegris Delaware) will be converted into the right to receive 1.39 fully paid and nonassessable shares of Entegris Delaware common stock. Each issued and outstanding share of Entegris Delaware common stock before the effective time of the merger will remain outstanding.

 

No fractional shares of Entegris Delaware common stock will be issued in the merger. All fractional shares of Entegris Delaware common stock to which a holder of Mykrolis common stock would otherwise be entitled at the effective time of the merger will aggregated. Any fractional shares resulting from this aggregation will be paid in cash in an amount equal to that fraction of the per-share closing sale price of Entegris common stock (as predecessor to Entegris Delaware common stock) on The NASDAQ National Market on the trading day immediately preceding the effective time of the merger. No interest will be paid or accrued on any cash payable for fractional shares.

 

The merger consideration will be appropriately adjusted to reflect any stock split, stock dividend, recapitalization, reorganization, reclassification, exchange, subdivision, combination of, or other similar change in Entegris common stock, Entegris Delaware common stock or Mykrolis common stock after the date of the merger agreement and prior to the effective time of the merger.

 

Exchange of Shares

 

At or immediately following the effective time of the merger, Entegris Delaware will deposit with the exchange agent, for the benefit of the holders of Mykrolis common stock, all certificates representing shares of Entegris Delaware common stock issuable in the merger in exchange for outstanding shares of Mykrolis common stock and will agree in writing with the exchange agent to deposit with the exchange agent as needed such amount of cash as is sufficient to pay for fractional shares. Entegris Delaware will provide additional amounts of cash, if any, needed from time to time by the exchange agent to pay, without interest, cash in lieu of fractional shares.

 

After the effective time of the merger, no further registrations of transfers on the stock transfer books of Entegris Delaware or Mykrolis of the shares of Mykrolis common stock will be made. If, after the effective time of the merger, Mykrolis stock certificates are presented to Entegris Delaware or the exchange agent for any reason, they will be canceled and exchanged as described in this section, except as otherwise provided by law.

 

As soon as practicable after the effective time of the merger, the exchange agent will mail to each record holder of a Mykrolis stock certificate whose shares of Mykrolis common stock were converted into the right to receive the merger consideration, a letter of transmittal and instructions explaining how to surrender Mykrolis stock certificates in exchange for the merger consideration.

 

After the effective time of the merger, upon surrender of a Mykrolis stock certificate to the exchange agent, together with the letter of transmittal, duly executed, and other documents as may reasonably be required by the exchange agent, the holder of the Mykrolis stock certificate will be entitled to receive (i) one or more certificates requested by the holder representing the number of whole shares of Entegris Delaware common stock to which the holder is entitled pursuant to the merger agreement; and (ii) as to any fractional share, a check representing the cash consideration to which the holder is entitled under the merger agreement, and the Mykrolis stock certificate so surrendered will be cancelled.

 

Mykrolis stockholders desiring to receive payment upon the surrender of Mykrolis stock certificates registered in the name of another person will receive payment if the stock certificates have been properly endorsed or are otherwise in proper form for transfer and the stockholders:

 

    pay any transfer or other taxes required because the payment is made to a person other than the registered holder of the Mykrolis stock certificate; or

 

78


Table of Contents
    establish to the satisfaction of the exchange agent that any transfer or other taxes described above have been paid or are not applicable.

 

In the case of any lost, stolen or destroyed Mykrolis stock certificates, the holder thereof may be required, as a condition precedent to the delivery to the holder of the merger consideration, to deliver to Entegris Delaware a written indemnity agreement in form and substance reasonably acceptable to Entegris Delaware and, if reasonably deemed advisable by Entegris Delaware, a bond in such reasonable sum as Entegris Delaware may direct as indemnity against any claim with respect to the certificate alleged to have been lost, stolen or destroyed.

 

Mykrolis stock certificates should not be returned with the enclosed proxy card(s). Mykrolis stock certificates should only be returned with a validly executed transmittal letter and accompanying instructions that will be provided to Mykrolis stockholders following the effective time of the merger.

 

Certain Post-Merger Governance Matters; Directors and Officers; Headquarters

 

Entegris and Mykrolis have agreed to take all actions necessary so that at the effective time of the merger:

 

    the certificate of incorporation and bylaws of Entegris Delaware will be in the forms agreed upon pursuant to the merger agreement (or such other form as may be agreed to by the parties), subject to the receipt of the requisite approval of the Entegris stockholders at the Entegris special meeting;

 

    the Entegris Delaware board of directors will initially consist of ten directors, five of whom initially will be then-existing Entegris directors designated by Entegris and five of whom initially will be then-existing Mykrolis directors designated by Mykrolis, except that following a recommendation by the chief executive officer of Entegris Delaware and the chairman of Entegris Delaware, but through nomination by the nominating and governance committee of the Entegris Delaware board of directors, and approval by the Entegris Delaware board of directors, one additional director will be added to the board of directors;

 

    the Entegris Delaware board of directors will have standing audit, nominating and governance and compensation committees, each comprised of an equal number of directors designated by Entegris and by Mykrolis;

The parties have agreed that all rights to indemnification, expense advancement and exculpation in favor of any present or former director, officer or employee of Entegris, Mykrolis or any of their respective subsidiaries as provided in the charter documents of such entity or by law as in effect on the date of the merger agreement will survive the merger for a period of at least six years after the effective time of the merger (or, if any relevant claim is asserted or made within such six-year period, until final disposition of such claim) with respect to matters occurring at or prior to the effective time of the merger. To the fullest extent permitted by law, Entegris Delaware will assume, at the effective time of the merger, all obligations provided by statute or charter or organizational documents of each of Entegris and Mykrolis in effect prior to the reincorporation merger and the merger in respect of indemnification and expense reimbursement of any present or former director, officer or employee of Entegris or Mykrolis if the relevant claim is made within six years after the effective time of the merger. Entegris Delaware will, after the effective time of the merger, abide by each of Mykrolis’ contractual obligations to provide indemnification and exculpation to any other person, to the extent of such contractual obligation, and will enter into indemnification agreements with all persons who were officers or directors of Entegris immediately prior to the reincorporation merger or who were officers or directors of Mykrolis immediately prior to the merger, in each case in substantially the form of indemnification agreements Mykrolis has with its officers and directors.

Entegris Delaware has agreed to maintain in effect for a period of at least six years after the date of the merger directors’ and officers’ liability insurance with respect to claims arising from facts or events that occurred at or prior to the effective time of the merger, and such policies will name as insureds all present and former directors and officers of Entegris, Mykrolis and their respective subsidiaries. Such insurance policies will consist of the current policies of directors’ and officers’ insurance maintained by Entegris and Mykrolis (or substitute policies with at least the same coverage and amounts containing terms and conditions which are no less advantageous in any material respect to the insured parties) or a run-off policy or endorsement with respect to the current policy covering claims asserted within six years after the effective time of the merger arising from facts or events that occurred at or before the effective time of the merger. However, Entegris Delaware will not be required to expend in any one year an amount in excess of 200% of the annual premium paid by Entegris or Mykrolis at the date of the merger agreement for the insurance, provided that if the annual premium of insurance coverage exceeds that amount, Entegris Delaware will be obligated to obtain a policy with the greatest coverage available for a cost not exceeding that amount.

    engage in discussions or negotiations or enter into any agreement with any person or group other than the other applicable party or its affiliates concerning any third party acquisition proposal, or provide any non-public information regarding, or afford access to the properties, books, records or personnel of, the applicable party or any of its subsidiaries, to any third party that is considering making, or has made, any third party acquisition proposal; or

 

    agree to or recommend any third party acquisition proposal.

 

Notwithstanding the foregoing, each of Entegris and Mykrolis may, at any time prior to obtaining the approval of its stockholders of the merger and if the applicable party is not in material breach of its non-solicitation obligations, furnish non-public information pursuant to a confidentiality agreement at least as favorable to the applicable party as the confidentiality agreements described in the merger agreement or afford access to the properties, books, records, and personnel of the applicable party or any of its subsidiaries to, or enter into discussions or negotiations with, any third party in connection with a third party acquisition proposal by such third party or recommend any third party acquisition proposal, in each case if the board of directors of the applicable party, in the exercise of its fiduciary duties, determines in good faith by majority vote (after consultation with its legal and financial advisers) that the third party acquisition proposal is reasonably likely to result in a “superior proposal” (as defined below).

 

As used in this joint proxy statement/prospectus, “third party acquisition proposal” means any inquiries or proposals from any person or group other than the other applicable party or its affiliates relating to:

 

    a merger, consolidation or business combination involving the applicable party or any of its subsidiaries (other than a merger of a wholly owned subsidiary of an applicable party into the applicable party or another of its wholly owned subsidiaries);

 

89


Table of Contents
    a sale of assets representing an amount equal to or greater than 25% of the consolidated assets of the applicable party and its subsidiaries taken as a whole (other than the sale or other disposition of inventory or obsolete equipment in the ordinary course of business consistent with past practice);

 

    a sale of shares of capital stock of the applicable party or any of its subsidiaries (including without limitation by way of a tender offer or exchange offer) that would result in any person or group beneficially owning 10% or more of any class or series of equity securities of the applicable party or any of its subsidiaries or any similar transaction involving the applicable party or any of its subsidiaries, other than the transactions required by the merger agreement; or

 

    the consummation of any other transaction or the entering into of any other agreement or arrangement with respect to any other transaction, the effect of which would have the same result as the occurrence of any of the events described in the preceding three bullet points.

 

As used in this joint proxy statement/prospectus, “superior proposal” means a third party acquisition proposal (except that all references to “10% or more” or “25%” in the definition of third party acquisition proposal shall be deemed to be references to “a majority”) that was not solicited in violation the merger agreement and that, in the good faith judgment of the board of directors of the applicable party, taking into account, to the extent deemed appropriate by such board of directors, the various legal, financial and regulatory aspects of the third party acquisition proposal and the person or group making such proposal, if accepted, is reasonably likely to be consummated and if consummated, is reasonably likely to result in a transaction that is more favorable to the applicable party’s stockholders from a financial point of view than the transactions contemplated by the merger agreement.

 

Each of Entegris and Mykrolis has agreed not to release any third party from, or waive any provision of, any confidentiality or standstill agreement to which it is a party, unless its board of directors, in the exercise of its fiduciary duties, determines in good faith by a majority vote (after consultation with its financial and legal advisers) that such action is required. Notwithstanding anything stated in the non-solicitation provisions of the merger agreement, neither party need refuse a request from any person who has signed a standstill agreement with such party to make a third party acquisition proposal to the chief executive officer or the board of directors thereof if the board of directors determines in good faith by a majority vote, in the exercise of its fiduciary duties, after consultation with its legal counsel, that such action is required. Nothing in the non-solicitation provisions of the merger agreement will operate to hinder or prevent either party from complying with Rule 14e-2 or Rule 14d-9 under the Securities Exchange Act of 1934 with regard to a third party acquisition proposal, but compliance with such rules will not in any way limit or modify the effect that any action taken pursuant to such rules has under the provisions of the merger agreement relating to termination or termination fees and expenses.

 

Each party is required to notify the other promptly (but in no event later than 24 hours) after receipt by such party (or any of its advisers) of any request (other than in the ordinary course of business and not related to a third party acquisition proposal) for non-public information relating to it or any of its subsidiaries or for access to its properties, books or records or any of its subsidiaries by any person who is known to be considering making, or has made, a third party acquisition proposal or of an inquiry from a third party seeking to have discussions or negotiations relating to, or make, a possible third party acquisition proposal. Such notice must be provided orally and in writing and must identify the terms and conditions of any such third party acquisition proposal, indication or request, including the identity of the party making the third party acquisition proposal, indication or request and shall be accompanied by copies of all agreements or proposed agreements related thereto. Each applicable party shall keep the other reasonably informed, on a prompt basis (but in any event no later than 24 hours following any written correspondence from any person known to be contemplating a third party acquisition proposal), of the status and details of any such third party acquisition proposal, indication or request and shall provide such other party with copies of all agreements and proposed agreements related to such third party acquisition proposal.

Change of Recommendation

 

Each of Entegris and Mykrolis has agreed that neither its board of directors nor any committee of its board of directors will effect a change of recommendation (as defined below) or adopt, approve or recommend to such party’s stockholders that they accept, or propose publicly to adopt, approve or recommend, any third party acquisition proposal. However, each of Entegris and Mykrolis may effect a change of recommendation if its board of directors, in the exercise of its fiduciary duties, determines in good faith by a majority vote, after consultation with its outside counsel, that the change of recommendation is necessary to satisfy its fiduciary duties. In addition, if the change of recommendation results from the receipt of a superior proposal, then, prior to making the change of recommendation, the applicable party receiving the superior proposal shall

 

    provide the other party five business days prior written notice that its board of directors intends to take such action (unless at the time such notice is otherwise required to be given, there are fewer than five business days prior to the applicable party’s stockholder meeting or the five business day notice would make impractical compliance with Rules 14e-2(a) or 14d-9 of the Securities Exchange Act of 1934, in which case as much notice as is reasonably practical shall be provided) specifying the material terms and conditions of the superior proposal (and providing a written copy thereof) and identifying the person or persons making the superior proposal; and

 

    if, during the foregoing five business day period, the party receiving the notice of the superior proposal shall make a counterproposal to the party that is proposing to effect a change of recommendation, the party that is proposing to take such action shall consider and cause its financial and legal advisers to negotiate on its behalf in good faith with respect to the terms of any such counterproposal.

 

For purposes of this joint proxy statement/prospectus, “change of recommendation” means that the board of directors of Entegris or Mykrolis (as applicable) or any committee of such board of directors has withdrawn, amended or modified, or proposed publicly to withdraw, amend or modify, in a manner adverse to the other party, the approval or recommendation by such board of directors or any such committee of the merger agreement or the transactions contemplated by the merger agreement.

 

Termination of the Merger Agreement

 

The merger agreement may be terminated at any time before the effective time of the merger, whether before or after approval by the stockholders of Entegris and/or the stockholders of Mykrolis, in any of the following ways:

 

    by the mutual written consent of Entegris and Mykrolis;

 

    by either Entegris or Mykrolis:

 

    if the merger has not been consummated on or before December 31, 2005, or a later date, if any, upon which the parties agree (referred to in this joint proxy statement/prospectus as the “termination date”), provided that the failure to consummate the merger by the termination date is not due to the failure of the party seeking to terminate the merger agreement to comply in all material respects with its obligations under the merger agreement;

 

    if Entegris or Mykrolis stockholders fail to give the necessary approvals described in this joint proxy statement/prospectus at the first such stockholder meeting called for that purpose or any adjournment of that meeting; or

 

    if any statute, rule or regulation that makes consummation of the merger illegal or otherwise prohibited or if any judgment, injunction, order or decree (which judgment, injunction, order or decree Entegris and Mykrolis must use its reasonable best efforts to lift) of any court or other governmental body having competent jurisdiction enjoins Entegris or Mykrolis from consummating the merger and such judgment, injunction, order or decree shall have become final and non-appealable;

    by Entegris:

 

    if any of the conditions to Entegris’ obligation to effect the merger have become impossible to fulfill other than for reasons within the control of Entegris or Entegris Delaware (except that Entegris does not have the right to terminate the merger agreement solely on the ground that the reincorporation merger shall become impossible to fulfill);

 

    if the board of directors of Mykrolis fails to recommend the merger agreement and the merger to Mykrolis’ stockholders or effects a change of recommendation or resolves to do any of the foregoing;

 

    if Mykrolis fails to comply in all material respects with the non-solicitation provisions of the merger agreement described above in the section entitled “No Solicitation”;

 

    if the board of directors of Mykrolis or any committee thereof recommends or approves a third party acquisition proposal or the Mykrolis board of directors resolves to do so; or

 

    if the board of directors of Mykrolis fails to hold the Mykrolis stockholder meeting in accordance with the merger agreement or resolves to do so;

 

    by Mykrolis:

 

    if any of the conditions to Mykrolis’ obligation to effect the merger have become impossible to fulfill other than for reasons within the control of Mykrolis;

 

    if the board of directors of Entegris fails to recommend the merger agreement and the merger and the reincorporation merger agreement and the reincorporation merger to Entegris’ stockholders or effects a change of recommendation or resolves to do any of the foregoing;

 

    if Entegris fails to comply in all material respects with the non-solicitation provisions of the merger agreement described above in the section entitled “No Solicitation”;

 

    if the board of directors of Entegris or any committee thereof recommends or approves a third party acquisition proposal or the Entegris board of directors resolves to do so; or

 

    if the board of directors of Entegris fails to hold the Entegris stockholder meeting in accordance with the merger agreement or resolves to do so.

 

If the merger agreement is validly terminated, it will become void without any liability on the part of any party, except as otherwise provided in the provisions of the merger agreement relating to certain fees and expenses (which are summarized below in the section entitled “––Termination Fees and Expenses”) and except to the extent the termination is a direct result of a willful and material breach or violation by such party of a representation, warranty, covenant or agreement contained in the merger agreement. The confidentiality agreements entered into between Entegris and Mykrolis will continue in effect notwithstanding termination of the merger agreement.

 

Termination Fees and Expenses

 

Each of Mykrolis and Entegris has agreed to pay the other party a termination fee equal to $23,500,000 by wire transfer of immediately available funds, plus all transaction expenses of the other party (up to a maximum of $1,500,000), if prior to the paying party’s stockholder meeting a third party acquisition proposal has been made to the paying party and has become known publicly or has been made directly to the paying party’s stockholders generally or any person has publicly announced an intention (whether or not conditional) to make a third party acquisition proposal relating to the paying party and:

 

   

the merger agreement is terminated by either party because the merger has not been consummated by the termination date and within 12 months after such termination, the paying party or any of its

 

92


Table of Contents
 

subsidiaries consummates a third party acquisition proposal or enters into a definitive agreement with respect to a third party acquisition proposal that is subsequently consummated within or after this 12-month period;

 

    the merger agreement is terminated by the non-paying party because the paying party’s stockholder meeting has concluded and the paying party’s stockholder approval is not obtained, and within 12 months of such termination, the paying party or any of its subsidiaries consummates a third party acquisition proposal or enters into a definitive agreement with respect to a third party acquisition proposal that is subsequently consummated within or after this 12-month period; or

 

    the merger agreement is terminated by the non-paying party because the condition to closing relating to the accuracy of the paying party’s representations and warranties, the performance of the paying party’s obligations under the merger agreement or the lack of a material adverse change of the paying party has not been satisfied or waived, and within 12 months of such termination the paying party or any of its subsidiaries consummates a third party acquisition proposal or enters into a definitive agreement with respect to a third party acquisition proposal that is subsequently consummated within or after this 12-month period.

 

In addition, Entegris or Mykrolis, as applicable, must pay the other party the $23,500,000 termination fee plus the transaction expenses of the other party (up to a maximum of $1,500,000) if:

 

    the other party terminates the merger agreement because the paying party’s board of directors has:

 

    effected a change of recommendation;

 

    recommended or approved any third party acquisition proposal or any committee of such paying party’s board of directors has done so;

 

    materially breached its obligations with respect to holding the paying party’s stockholder meeting; or

 

    resolved to do any of the foregoing;

 

or

 

    the other party terminates the merger agreement because the paying party has materially breached its non-solicitation obligations under the merger agreement.

 

For purposes of determining whether a third party acquisition proposal has been consummated that may entitle Entegris or Mykrolis to the termination fee and expense reimbursement described above, references to “10% or more” or “25% or more” in the definition of third party acquisition proposal will be deemed to be “a majority.”

 

In general, each of Entegris, Entegris Delaware and Mykrolis will bear its own expenses in connection with the merger agreement and the related transactions except that Entegris and Mykrolis will share equally the costs and expenses in connection with the filing of the registration statement of which this joint proxy statement/prospectus is a part, the printing and mailing of this joint proxy statement/prospectus, and filing fees under any U.S. or foreign antitrust or competition laws.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

 

The following unaudited pro forma condensed combined financial statements are presented to illustrate the effects of the merger on the historical financial position and operating results of Entegris and Mykrolis after giving effect to the merger as a purchase of Mykrolis by Entegris using the purchase method of accounting, and the assumptions and adjustments described in the accompanying notes to the unaudited pro forma condensed combined financial statements.

 

The unaudited pro forma condensed combined financial statements are presented for informational purposes only and are not necessarily indicative of the financial position or results of operations of Entegris that would have occurred had the merger been consummated as of the dates indicated. In addition, the pro forma condensed combined financial statements are not necessarily indicative of the future financial condition or operating results of Entegris.

 

The following unaudited pro forma condensed combined balance sheet as of February 26, 2005 is presented to give effect to the proposed merger as if it occurred on February 26, 2005 and, due to different fiscal period ends, combines the historical consolidated balance sheet for Entegris at February 26, 2005 and the historical consolidated balance sheet of Mykrolis at December 31, 2004.

 

The unaudited pro forma condensed combined statements of operations for the year ended August 28, 2004 and the six months ended February 26, 2005 are presented as if the merger had taken place on August 31, 2003. Due to different fiscal period ends, the unaudited pro forma condensed combined statement of operations for the year ended August 28, 2004 combines the historical results of Entegris for the year ended August 28, 2004 and the historical results of Mykrolis for the twelve months ended July 3, 2004. The unaudited pro forma condensed combined statement of operations for the six months ended February 26, 2005 combines the historical results of Entegris for the six months ended February 26, 2005 and the historical results of Mykrolis for the six months ended December 31, 2004.

 

The historical results of Mykrolis for the twelve months ended July 3, 2004 contained in the unaudited pro forma condensed combined statement of operations have been derived from Mykrolis’ audited consolidated statement of operations for the year ended December 31, 2003 and Mykrolis’ unaudited consolidated statements of operations for the six months ended June 28, 2003 and July 3, 2004. The historical results of Mykrolis for the six months ended December 31, 2004 contained in the unaudited pro forma condensed combined statement of operations have been derived from Mykrolis’ audited consolidated statement of operations for the year ended December 31, 2004 and Mykrolis’ unaudited consolidated statement of operations for the six months ended July 3, 2004.

 

The merger will be accounted for under the purchase method of accounting in accordance with Statement of Financial Accounting Standards No. 141, Business Combinations (“SFAS 141”). Under the purchase method of accounting, the total estimated purchase price, calculated as described in Note 1 to these unaudited pro forma condensed combined financial statements, is allocated to the net tangible and identifiable intangible assets of Mykrolis acquired in connection with the merger, based on their respective estimated fair values. Management has made a preliminary allocation of the estimated purchase price to the tangible and identifiable intangible assets acquired and liabilities assumed based on various preliminary estimates. A final determination of these estimated fair values, which cannot be made until after the completion of the merger, will be based on the actual net tangible and identifiable intangible assets of Mykrolis that exist as of the date of completion of the merger.

 

These unaudited pro forma condensed combined financial statements have been prepared based on preliminary estimates of fair values. Amounts preliminarily allocated to intangible assets with finite lives may change significantly, which could result in a material change in amortization of intangible assets. Therefore, the actual amounts recorded as of the completion of the merger may differ materially from the information presented in these unaudited pro forma condensed combined financial statements.

 

Further, the unaudited pro forma condensed combined financial statements do not include any adjustments for liabilities that may result from integration activities, as management of Entegris and Mykrolis are in the

process of making these assessments, and estimates of these costs are not currently known. However, liabilities ultimately may be recorded for severance or relocation costs related to Mykrolis employees, costs of vacating some facilities of Mykrolis, or other costs associated with exiting activities of Mykrolis that would affect amounts in the pro forma financial statements. Any such liabilities would be recorded as an adjustment to the purchase price and an increase in goodwill. In addition, Entegris may incur significant restructuring charges upon completion of the merger or in subsequent quarters for severance or relocation costs related to Entegris employees, costs of vacating some facilities of Entegris, or other costs associated with exiting activities of Entegris. Any such restructuring charges would be recorded as an expense in the consolidated statement of operations of Entegris in the period in which they were incurred.

 

The unaudited pro forma operating data and balance sheet data set forth below are not necessarily indicative of the results that actually would have been achieved had the proposed merger been consummated on August 31, 2003 for the operating data and as of February 26, 2005 for the balance sheet data, or that may be achieved in the future.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED

FINANCIAL STATEMENTS

 

1. Basis of Pro Forma Presentation

 

On March 21, 2005, Entegris and Mykrolis entered into a definitive merger agreement under which Entegris will merge with and into Eagle DE, Inc., its wholly owned subsidiary (which we refer to in this joint proxy statement/prospectus as “Entegris Delaware”), and Mykrolis will then merge with and into Entegris Delaware in a business combination to be accounted for using the purchase method. In connection with the mergers, Entegris Delaware will be renamed Entegris, Inc. The total estimated purchase price of $641.0 million includes the issuance of Entegris Delaware common stock valued at $579.5 million, assumed stock options with a fair value of $54.3 million and estimated direct transaction costs of Entegris of $7.2 million.

 

The unaudited pro forma condensed combined financial statements assume the issuance in the merger of approximately 58.3 million shares of Entegris Delaware common stock, based on an exchange ratio of 1.39 shares of Entegris Delaware common stock for each outstanding share of Mykrolis common stock as of March 21, 2005. The average market price per share of Entegris common stock of $9.94 is based on an average of the closing market price of Entegris common stock for the period beginning two trading days before and ending two trading days after the merger agreement was announced. The actual number of shares of Entegris Delaware common stock to be issued will be determined based on the actual number of shares of Mykrolis common stock outstanding immediately prior to the completion of the merger.

 

Under the terms of the merger agreement, each outstanding option to purchase Mykrolis common stock will be assumed by Entegris Delaware and converted into an option to purchase Entegris Delaware common stock. Under the terms of the merger agreement, Entegris Delaware will assume Mykrolis stock options to purchase approximately 6.8 million shares of Mykrolis common stock (which will be converted into options to acquire approximately 9.4 million shares of Entegris Delaware common stock), based on outstanding Mykrolis stock options as of March 21, 2005. The fair value of the outstanding options of $54.3 million was determined using a Black-Scholes valuation model with the following weighted-average assumptions: volatility of 75%; risk-free interest rate of 2.5%; expected life of 4.0 years; and dividend yield of zero. The actual number of stock options to be assumed will be determined based on the actual number of Mykrolis stock options outstanding immediately prior to the completion of the merger. In accordance with the terms of Mykrolis’ equity-based plans and related agreements, all of Mykrolis’ outstanding options will vest prior to or upon consummation of the merger, with the exception of options held by certain members of Mykrolis’ management.

 

In connection with the merger, it is anticipated that Entegris Delaware will issue an aggregate of 1.6 million shares of restricted stock to certain officers and employees. The estimated value of the restricted stock is $15.9 million. These restricted stock awards would vest 37.5% on December 31, 2005, and an additional 5.21% on the last business day of each of the first 12 fiscal quarters of Entegris Delaware following the completion of the merger. The unaudited pro forma condensed combined statements of operations include compensation expense based on the aforementioned vesting schedule.

 

Intercompany balances or transactions between Entegris and Mykrolis were eliminated. No pro forma adjustments were required to conform Mykrolis’ accounting policies to Entegris’ accounting policies. Certain reclassifications have been made to conform Mykrolis’ historical amounts to Entegris’ presentation.

 

Independent valuation specialists are currently conducting an independent valuation in order to assist management of Entegris in determining the fair values of a significant portion of Mykrolis’ assets. The preliminary work performed by the independent valuation specialists has been considered in management’s estimates of the fair values reflected in these unaudited pro forma condensed combined financial statements. A final determination of these fair values, which cannot be made prior to the completion of the merger, will include management’s consideration of a final valuation prepared by the independent valuation specialists. This final valuation will be based on the actual net tangible and intangible assets of Mykrolis that exist as of the date of completion of the merger.

 

The estimated purchase price and the allocation of the estimated purchase price discussed below are preliminary because the merger has not yet been completed. The actual purchase price will be based on the shares

(1) Relates to the net decrease in depreciation expense resulting from the adjustment to fair value of the fixed assets.
(2) Reflects an increase in cost of goods sold of $23.1 million related to the revaluation of certain inventory to fair value. This charge is non-recurring and as such is not reflected in the unaudited pro forma condensed combined statements of operations.
(3) Relates to compensation expense associated with unvested stock options assumed.

 

A preliminary estimate of $238.8 million has been allocated to net tangible assets acquired and $79.8 million has been allocated to identifiable intangible assets acquired. The depreciation and amortization related to the fair value adjustment to net tangible assets and the amortization related to the identifiable intangible assets are reflected as pro forma adjustments to the unaudited pro forma condensed combined statements of operations.

 

Identifiable intangible assets. Of the total estimated purchase price, $79.8 million has been allocated to developed technology, trademarks and trade names and customer relationships. This adjustment is preliminary and is based on Entegris management’s estimates. The amount ultimately allocated to identifiable intangible assets may differ materially from this preliminary allocation. A $5.0 million increase or decrease in value

FINANCIAL STATEMENTS—(Continued)

 

allocated to the amortizable intangible assets would increase or decrease annual amortization by approximately $0.8 million.

 

Identification and allocation of value to the identified intangible assets was based on the provisions of SFAS 141. The fair value of the identified intangible assets was estimated by performing a discounted cash flow analysis using the “income” approach. This method includes a forecast of direct revenues and costs associated with the respective intangible assets and charges for economic returns on tangible and intangible assets utilized in cash flow generation. Net cash flows attributable to the identified intangible assets are discounted to their present value at a rate commensurate with the perceived risk. The projected cash flow assumptions considered contractual relationships, customer attrition, eventual development of new technologies and market competition.

 

Amounts allocated to the identifiable intangible assets are expected to be amortized over a life of four to ten years. The estimates of expected useful lives are based on guidance from SFAS No. 141 and take into consideration the effects of competition, product lives and possible obsolescence. The useful lives of developed technology, and trademarks and trade names are based on the number of years in which net cash flows have been projected. The useful lives of customer relationships was estimated based upon Mykrolis’ established and long-standing customer relationships with its major customers and the number of years in which net cash flows have been projected.

 

Assumptions used in forecasting cash flows for each of the identified intangible assets included consideration of the following:

 

    Mykrolis historical operating margins

 

    Mykrolis market share and growth

 

    Trends in technology

 

    The nature and expected timing of new product introductions by Mykrolis and its competitors.

 

Goodwill. Of the total estimated purchase price, approximately $313.2 million has been allocated to goodwill. Goodwill represents the excess of the purchase price over the fair value of the underlying net tangible and intangible assets. In accordance with SFAS No. 142, goodwill resulting from business combinations will not be amortized but instead will be tested for impairment at least annually (more frequently if certain indicators are present). In the event the management of the combined company determines that the value of goodwill has become impaired, the combined company will incur an accounting charge for the amount of impairment during the fiscal quarter as of which the determination is made.

 

Net deferred tax assets and liabilities. The net current deferred tax assets and the deferred tax liabilities reflect the estimated tax effect related to the differences between the value of assets and liabilities for financial statement purposes and their basis for tax purposes under purchase accounting. This determination is preliminary and subject to change based upon management’s final valuation of the fair values of assets acquired.

 

In-process research and development. Of the total estimated purchase price, no amount was allocated to in-process research and development. Accordingly, no amount will be charged to expense in connection with in-process research and development in the period during which the merger is completed.

 

2. Pro Forma Adjustments

 

Pro forma adjustments are necessary to reflect the estimated purchase price, to reflect amounts related to Mykrolis’ net tangible and intangible assets at an amount equal to the preliminary estimate of their fair values, to reflect the amortization expense related to the estimated amortizable intangible assets, to reflect changes in depreciation and amortization expense resulting from the estimated fair value adjustments to net tangible assets, to eliminate intercompany balances and transactions between Entegris and Mykrolis, and to record the related income tax effect of these adjustments.

(h) To record goodwill

 

(i) To record the fair value of Entegris shares exchanged in the transaction

 

(j) To record the fair value of Mykrolis stock options assumed

 

(k) To adjust Mykrolis’ inventory to fair value less selling profit. This adjustment will result in an increase in cost of products upon the sale of the related inventory. This increase in costs is non-recurring and accordingly is not reflected in the pro forma condensed combined statements of operations

 

(l) To adjust Mykrolis’ property, plant and equipment to fair value

 

(m) To record the deferred tax assets and liabilities associated with the difference in the basis of certain assets and liabilities between book and tax

 

(n) To eliminate intercompany receivables and payables

 

(o) To eliminate intercompany profit in Mykrolis’ inventory

 

(p) To record amortization of intangible assets

(r) To eliminate intercompany sales, related cost of goods sold and change in intercompany profit held in inventory

 

(s) To record amortization of deferred stock-based compensation expense associated with unvested Mykrolis stock options assumed

 

(t) To record issuance of, and compensation expense associated with, restricted stock

 

(u) To adjust the Mykrolis tax rate to an estimated effective tax rate and to record income tax expense (benefit) associated with other pro forma adjustments

 

(v) To eliminate Mykrolis’ historical amortization expense of its amortizable intangible assets

 

3. Deferred Stock-Based Compensation.

 

This represents the estimated intrinsic value of the unvested Mykrolis stock options assumed and the issuance of restricted stock. The estimated intrinsic value was calculated as the difference between the average of the quoted closing market price of Entegris stock for the period beginning two days before and ending two days after the merger agreement was announced, and either the exercise price of the assumed unvested Mykrolis stock options, or zero in the case of the restricted stock. This balance will be amortized over the remaining vesting period of the stock options and over the vesting period of the restricted stock.

4. Pro Forma Earnings Per Share

 

Pro forma basic earnings per share is based on the number of shares of Entegris common stock used in computing basic earnings per share and the weighted average number of shares of Mykrolis common stock outstanding multiplied by the exchange ratio of 1.39.

 

Pro forma diluted earnings per share is based on the number of shares of Entegris common stock used in computing diluted net income per share plus the weighted average number of shares of Mykrolis common stock outstanding multiplied by the exchange ratio of 1.39 and the potential dilution from assumed dilutive stock options (using the treasury stock method).

DESCRIPTION OF ENTEGRIS DELAWARE’S CAPITAL STOCK

 

The following is a summary of the material terms of the capital stock of Entegris Delaware. Because it is only a summary, it is not meant to be complete and does not contain all of the information that may be important to you. Accordingly, for a complete description of the rights and preferences of Entegris Delaware’s capital stock, you should carefully read the full copies of Entegris Delaware’s proposed certificate of incorporation and bylaws attached as Annex C-1 and Annex D to this joint proxy statement/prospectus, the certificate of incorporation without classified board provisions attached as Annex C-2 hereto, and the applicable provisions of the Delaware General Corporation Law. See “Where You Can Find More Information” beginning on page [    ].

 

If Entegris’ reincorporation from a Minnesota corporation to a Delaware corporation and the merger are approved and adopted at the Entegris stockholder meeting, Entegris’ stockholders, whose rights are currently governed by Minnesota law and Entegris’ articles of incorporation and bylaws, will become stockholders of Eagle DE, Inc., a Delaware corporation, which we refer to in this joint proxy statement/prospectus as Entegris Delaware. Accordingly, following completion of the reincorporation, the rights of Entegris Delaware’s stockholders will be governed by Delaware law and Entegris Delaware’s certificate of incorporation and bylaws. For more information on certain differences in the rights of stockholders that arise from distinctions between Minnesota law and Delaware law, as well as from differences between Entegris’ articles of incorporation and bylaws and the certificate of incorporation and bylaws proposed for Entegris Delaware, see “Comparison of Rights of Stockholders” beginning on page [    ].

 

How Entegris Delaware’s certificate of incorporation and bylaws will read at the time of the reincorporation depends on whether or not proposal 3 to be presented at the Entegris stockholder meeting is approved. If proposal 3 is approved, the certificate of incorporation will read as set forth in Annex C-1 to this joint proxy statement/prospectus and the bylaws will read as set forth on Annex D to this joint proxy statement/prospectus. If proposal 3 is not approved, the certificate of incorporation will read as set forth on Annex C-2 to this joint proxy statement/prospectus and the bylaws attached as Annex D to this joint proxy statement/prospectus will be amended by the board of directors of Entegris Delaware to remove the classified board provisions and include provisions that are substantially similar to Article IX set forth in Annex C-2 but will otherwise read as set forth on Annex D. The following discussion assumes the approval of the reincorporation proposal and the classified board proposal and that the certificate of incorporation of Entegris Delaware attached as Annex C-1 and the bylaws of Entegris Delaware attached as Annex D to this joint proxy statement/prospectus are currently in effect.

 

Authorized Capital Stock

 

Under Entegris Delaware’s certificate of incorporation, the authorized capital stock of Entegris Delaware is 405,000,000 shares, consisting of 400,000,000 shares of common stock, par value $0.01 per share, and 5,000,000 shares of preferred stock, par value $0.01 per share.

 

Entegris Delaware Common Stock

 

In connection with the reincorporation merger, each share of Entegris Delaware common stock owned by Entegris will be cancelled and will cease to exist, and each share of Entegris common stock will be automatically converted into one share of Entegris Delaware common stock. As of the close of business on [                    ], 2005, there were [            ] shares of Entegris common stock outstanding.

 

The holders of Entegris Delaware common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders and do not have the right to cumulate votes in elections of directors. Holders of Entegris Delaware common stock are entitled to receive ratably such dividends as may be declared by the board of directors out of funds legally available therefor. In the event of Entegris Delaware’s liquidation, dissolution or winding up, holders of common stock are entitled to share ratably in all Entegris Delaware’s assets remaining after payment of liabilities and the liquidation preference of any then outstanding

preferred stock. Holders of Entegris Delaware common stock have no preemptive or other subscription or conversion rights. There are no redemption or sinking fund provisions applicable to the Entegris Delaware common stock.

 

The transfer agent and registrar for Entegris Delaware’s common stock will be Wells Fargo Bank Minnesota, N.A. at the time of the reincorporation.

 

Entegris Delaware Preferred Stock

 

Entegris Delaware’s certificate of incorporation authorizes Entegris Delaware’s board of directors to issue up to 5,000,000 shares of preferred stock without any vote or action by Entegris Delaware stockholders. Entegris Delaware’s board of directors may issue preferred stock in one or more series and determine the rights, preferences, privileges and restrictions granted or imposed upon any series of preferred stock, and the number of shares constituting each series. The preferred stock that can be authorized by Entegris Delaware’s board of directors could have preference over Entegris Delaware common stock with respect to dividends and other distributions and upon Entegris Delaware’s liquidation. In addition, the voting power of Entegris Delaware outstanding common stock may become diluted in the event that the board of directors issues preferred stock with voting rights.

 

Options

 

As of the close of business on [                    ], 2005, there were outstanding options to purchase an aggregate of [            ] shares of Entegris common stock at a weighted average exercise price of $[            ] per share, and restricted stock units convertible into [            ] shares of Entegris common stock. As of the close of business on [                    ], 2005, [            ] additional shares of Entegris common stock were reserved for future issuance under Entegris’ stock-based employee compensation plans.

 

Pursuant to the reincorporation merger agreement, upon the consummation of the reincorporation, each outstanding option to purchase shares of Entegris common stock and each restricted stock unit that may be surrendered for Entegris common stock that has been granted under any stock-based employee compensation plan of, or other arrangement with, Entegris will become an option or restricted stock unit, as the case may be, for the same number of shares Entegris Delaware common stock, subject to the same vesting schedule, forfeiture provisions and exercise price (if applicable).

 

Stockholder Rights Plan

 

Entegris Delaware expects that prior to the merger its board, as required by the merger agreement, will adopt a stockholder rights plan comparable to the existing Mykrolis stockholder rights plan, but with such modifications as the board of Entegris Delaware shall deem advisable. Entegris Delaware expects that pursuant to the contemplated stockholder rights plan, Entegris Delaware would declare a dividend shortly following the consummation of the merger to its stockholders of record on the date following the date of the merger of the right to initially purchase Entegris Delaware common stock or preferred stock that is structured as a common stock equivalent at a price per share or common stock equivalent, substantially in excess of the market price of Entegris Delaware common stock immediately following the merger, to be established by the Entegris Delaware board of directors prior to the merger. The Entegris Delaware rights would be attached to the shares of Entegris Delaware common stock until certain triggering events occur. As is the case under the Mykrolis stockholder rights plan, Entegris Delaware contemplates that the rights would be triggered by the acquisition by a person or group (an acquiring person, as defined in the Entegris Delaware stockholder rights plan), other than Entegris Delaware or any of Entegris Delaware’s subsidiaries or employee benefit plans, of 15% or more of the outstanding shares of Entegris Delaware common stock. In such event, the holder of a right paying the exercise price would be able to purchase, instead of one share of common stock or a fraction of a share of preferred stock, a number of shares of common stock of Entegris Delaware having a market value equal to twice the exercise price. In the event of certain mergers and similar transactions involving Entegris Delaware, shares of the other

 

112


Table of Contents

party to the transaction or its parent could be purchased at half of the market price of such shares by holders of the rights, as is the case under the Mykrolis stockholder rights plan. The Entegris Delaware rights would be redeemable by Entegris Delaware for $0.01 and would expire ten years after the record date for the rights dividend. An acquiring person would not be permitted to exercise an Entegris Delaware right. The intended effect of the stockholder rights plan would be to deter any person or group from becoming an acquiring person before the rights are redeemed because the ability of all rights holders other than the acquiring person to purchase shares of common stock at half price would substantially dilute the economic value and voting power of the acquiring person’s shares.

 

Anti-Takeover Effects of Provisions of Entegris Delaware’s Certificate of Incorporation, Bylaws, Stockholder Rights Plan and Delaware Law

 

Certificate of Incorporation and Bylaws

 

Entegris Delaware’s proposed certificate of incorporation provides that Entegris Delaware’s board of directors may issue, without stockholder action, up to 5,000,000 shares of preferred stock with voting or other rights. The rights of the holders of Entegris Delaware common stock may be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. The issuance of preferred stock may have the effect of delaying, deterring or preventing a change of control of Entegris Delaware without further action by the Entegris Delaware common stockholders and may adversely affect the voting and other rights of the holders of Entegris Delaware common stock. Under the contemplated Entegris Delaware stockholder rights plan, shares of preferred stock may be issued in certain events.

 

Entegris Delaware’s certificate of incorporation provides that stockholder action can be taken only at an annual or special meeting of stockholders and may not be taken by written consent in lieu of a meeting. This precludes stockholders from waging a proxy contest by written action. Moreover, Entegris Delaware’s bylaws provide that special meetings of stockholders, unless otherwise required by law, may be called only by the board of directors, chairman of the board of directors, or the chief executive officer. The combination of precluding stockholder actions by written consent and limiting the persons who may call a special meeting decreases the likelihood that stockholders can wage a proxy contest except in connection with an annual meeting of stockholders.

 

Entegris Delaware’s certificate of incorporation also provides that any amendments to the bylaws and specified amendments to the certificate of incorporation relating to the inability of stockholders to act by written action and the limitation upon who may call a special meeting of stockholders require the affirmative vote of the holders of at least seventy-five percent (75%) of the shares of the capital stock of Entegris Delaware issued and outstanding and entitled to vote generally in the election of the directors. In addition, vacancies and newly created directorships resulting from any increase in the size of Entegris Delaware’s board of directors may be filled only by the affirmative vote of a majority of the directors then in office, even if less than a quorum is present. These provisions could hinder stockholders in attempts to remove incumbent directors and fill the resulting vacancies with their own nominees.

 

For a description of the anti-takeover effects of the classified board proposal, see “The Classified Board Proposal—Reasons for and Effects of the Classified Board Proposal” beginning on page [    ].

 

These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control of Entegris Delaware management and could have the effect of discouraging others from making tender offers for Entegris Delaware shares or other acquisitions of Entegris Delaware. Consequently, they also may inhibit fluctuations in the market price of Entegris Delaware shares that could result from actual or rumored takeover attempts.

 

113


Table of Contents

Stockholder Rights Plan

 

Entegris Delaware’s contemplated stockholder rights plan will be designed to protect and maximize the value of Entegris Delaware’s outstanding equity interests in the event of an unsolicited attempt to acquire the company in a manner or on terms not approved by the board of directors and that prevent stockholders from realizing the full value of their shares of Entegris Delaware’s common stock. Its purposes will be to deter those takeover attempts that the board believes are undesirable, to give the board more time to evaluate takeover proposals and consider alternatives, and to increase the board’s negotiating position to maximize value in the event of a takeover. The rights issued pursuant to the plan are not intended to prevent all takeovers of Entegris Delaware.

 

However, the rights may have the effect of rendering more difficult or discouraging an acquisition of Entegris Delaware. The rights may cause substantial dilution to a person or group that attempts to acquire Entegris Delaware on terms or in a manner not approved by the board of directors, except pursuant to an offer conditioned upon the negation, purchase or redemption of the rights with respect to which the condition is satisfied.

 

Delaware Law

 

Entegris Delaware is subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, the statute prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” (who was not an interested stockholder before Entegris Delaware becomes a publicly held corporation) for a period of three years after the date that the person became an interested stockholder (the “interested date”) unless, subject to certain exceptions, the business combination or the transaction in which the person became an interested stockholder is approved by the board of directors prior to the interested date or the business combination is approved after the interested date by the board and the holders of two-thirds of the corporation’s outstanding voting shares, excluding any shares held by the interested stockholder, at an annual or special meeting. Generally, a “business combination” includes a merger, certain asset or stock sales or other transactions resulting in a financial benefit to the interested stockholder. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns, or within three years prior did own, 15% or more of the corporation’s voting stock. These provisions may have the effect of delaying, deferring or preventing a change in control of Entegris Delaware, including proposed transactions in which holders of Entegris Delaware common stock would receive a premium to the market price of the stock in exchange for their shares.

 

Entegris is currently subject to the anti-takeover provisions of the Minnesota Business Corporation Act. For a comparison of these Minnesota anti-takeover provisions with Section 203 of the Delaware General Corporation Law, see “Comparison of Rights of Stockholders” beginning on page [    ].

Table of Contents

COMPARISON OF RIGHTS OF STOCKHOLDERS

 

Entegris is a Minnesota corporation subject to the provisions of the Minnesota Business Corporation Act (or MBCA). If the reincorporation of Entegris from a Minnesota corporation to a Delaware corporation is approved by the Entegris stockholders (and the merger is approved by such stockholders and the stockholders of Mykrolis), the Entegris stockholders, whose rights are currently governed by the MBCA and Entegris’ articles of incorporation and bylaws, will become stockholders of Entegris Delaware governed by the Delaware General Corporation Law (or DGCL) and the certificate of incorporation and bylaws of Entegris Delaware. Certain differences in the rights of stockholders arise from distinctions between the MBCA and the DGCL, as well as from differences between the charter documents of Entegris and Entegris Delaware.

 

Mykrolis is a Delaware corporation subject to the provisions of the DGCL. Since the merger will not be completed until after the reincorporation, Mykrolis stockholders will continue to be governed by the DGCL both before and after the merger, but following the merger, the rights of such stockholders will be governed by the certificate of incorporation and bylaws of Entegris Delaware instead of the certificate of incorporation and bylaws of Mykrolis.

 

Set forth below is a summary comparison of the rights Entegris stockholders currently have under the MBCA and Entegris’ articles of incorporation and bylaws and the rights such stockholders would have following the merger under the DGCL and Entegris Delaware’s certificate of incorporation and bylaws (assuming for this purpose that the classified board proposal is also approved). The following discussion and summary comparison assume the approval of the reincorporation proposal and the classified board proposal and that the certificate of incorporation of Entegris Delaware attached as Annex C-1 and the bylaws of Entegris Delaware attached as Annex D to this joint proxy statement/prospectus are currently in effect.

 

Since Mykrolis stockholders will continue to be governed by the DGCL as stockholders of Entegris Delaware, the only differences in the rights of such stockholders following the merger would be attributable to differences between the Mykrolis certificate of incorporation and bylaws and the Entegris Delaware certificate of incorporation and bylaws. Because the Entegris Delaware certificate of incorporation and bylaws were modeled on the Mykrolis certificate of incorporation and bylaws, however, these differences are minimal. The principal differences between the Mykrolis charter documents and the Entegris Delaware charter documents are as follows:

 

1. The Entegris Delaware certificate of incorporation authorizes 400,000,000 shares of common stock (to reflect the combination of Entegris and Mykrolis), whereas the Mykrolis certificate of incorporation authorizes only 250,000,000 shares of common stock;

 

2. The provision of the Entegris Delaware certificate of incorporation which requires a 75% supermajority vote of the stockholders to amend the bylaws was conformed to other provisions of the certificate of incorporation which require a supermajority vote of the stockholders for action in order to clarify that, consistent with Section 242(b)(4) of the DGCL, such provision may be amended only by the same 75% supermajority vote that is necessary to amend the bylaws;

 

3. The Entegris Delaware certificate of incorporation omits various obsolete provisions contained in the Mykrolis certificate of incorporation relating to Mykrolis’ relationship with its former parent company;

 

4. Provisions relating to the indemnification of officers and directors contained in the Mykrolis certificate of incorporation have been relocated to the Entegris Delaware bylaws and revised in certain respects that remain substantively similar to the provisions in Mykrolis’ certificate of incorporation; and

 

5. Provisions of the Mykrolis certificate of incorporation which specifically authorize the Mykrolis board to consider factors beyond price in evaluating tender or exchange offers for the corporation’s equity securities have been omitted from the Entegris Delaware certificate of incorporation.

 

The foregoing comparison of rights of Mykrolis stockholders before and after the merger and the comparison below of the rights of Entegris stockholders before and after the reincorporation merger and the

merger are not intended to be a complete or exhaustive statement of all differences or similarities affecting the rights of such stockholders. The identification of certain differences or similarities is not meant to indicate that other differences do not exist.

 

For additional information regarding the specific rights of holders of Entegris Delaware’s capital stock, please see “Description of Entegris Delaware Capital Stock” beginning on page [    ]. Please also carefully read the relevant provisions of the MBCA and the DGCL, as well as the articles of incorporation and bylaws of Entegris, which are attached as Exhibits 3.3 and 3.4 to the Form S-4 registration statement of which this joint proxy statement/prospectus is a part, the certificate of incorporation and bylaws of Mykrolis, which are incorporated by reference into this joint proxy statement/prospectus, and the certificate of incorporation and bylaws of Entegris Delaware, including the proposed classified board of directors provisions, which are attached as Annex C-1 and Annex D to this joint proxy statement/prospectus. Please see “Where You Can Find More Information.” The discussion above and below is qualified in its entirety by reference to the foregoing documents.

 

    

Entegris Delaware Stockholder Rights


  

Entegris Stockholder Rights


General:

   The rights of Entegris Delaware stockholders are governed by Delaware law and Entegris Delaware’s certificate of incorporation and bylaws.    The rights of Entegris stockholders are governed by Minnesota law and Entegris’ articles of incorporation and bylaws.

Class of Common Stock:

   Entegris Delaware has only one class of common stock authorized or outstanding.    Entegris has only one class of common stock authorized or outstanding.

Preferred Stock:

   Entegris Delaware would be authorized to issue up to 5,000,000 shares of preferred stock in series, each for a number of shares as the board may determine and each having powers, rights (including voting rights), and preferences (including preferences with respect to dividends and upon liquidation) that are determined by the board. However, no preferred stock of Entegris Delaware is currently issued, and the board has not designated any series of preferred stock or established the powers, rights and preferences of any such series.    Entegris is not authorized to issue any preferred stock.
Number of Authorized Shares:    Entegris Delaware would have 400,000,000 authorized shares of common stock and 5,000,000 authorized shares of preferred stock.    Entegris has 200,000,000 authorized shares of common stock.

Entegris Delaware Stockholder Rights


  

Entegris Stockholder Rights


Number of Directors:

   Entegris Delaware’s certificate of incorporation and bylaws provide that the number of directors is fixed by resolution of the board, but in no event shall be less than three. Entegris Delaware contemplates that, as provided in the merger agreement, at the effective time of the merger, it will have ten directors, five of whom are presently Entegris directors and five of whom are presently Mykrolis directors. The merger agreement also provides that the new board may approve an eleventh member after the effective time of the merger who is recommended by the chief executive officer and the chairman of Entegris Delaware and nominated by the nominating and governance committee of Entegris Delaware.    Entegris’ bylaws permit up to nine directors. Entegris’ bylaws provide that any change in the number of directors must be approved by holders of at least 51% of the voting power of the outstanding shares unless the change is approved by a majority of the board. Entegris presently has eight directors.
Classification of Board of Directors:    Assuming the proposed Entegris Delaware certificate of incorporation attached as Annex C-1 to this joint proxy statement/prospectus is approved at the Entegris special meeting, Entegris Delaware’s certificate of incorporation and bylaws, like those of Mykrolis, will provide that Entegris Delaware’s board of directors be divided into three classes, with the terms of office of one class of directors expiring each year, resulting in each class serving a staggered three-year term (except during the initial three-year period). The classes must be substantially equivalent in size.    Entegris’ stockholders voted in 2003 to discontinue its classified board at the 2004 annual meeting, and each director elected at and after that meeting is elected to serve a term that expires at the next regular annual meeting of stockholders and when a successor is elected and has qualified or at the time the director dies, resigns or is removed or disqualified. No continuing director had his term reduced as a result of this amendment, so three of the directors would be eligible to serve until 2006 unless they die, resign or are removed prior to that date.

Board Vacancies:

   Under Entegris Delaware’s certificate of incorporation and bylaws, vacancies on the board would be filled only by a majority of the remaining directors, even if less than a quorum. A director replacing a predecessor director then serves for the unexpired term of the director being replaced unless the director dies, resigns or is removed before the end of the term. A director elected to fill a vacancy resulting from an increase in the number of directors serves until the next stockholder election of the class in which the director is chosen unless the director dies, resigns or is removed before the end of the term.    Under Entegris’ bylaws, vacancies on the board are filled by a majority of the remaining directors, even if less than a quorum. The director selected to fill the vacancy then serves until the next meeting of stockholders unless the director dies, resigns or is removed before the end of the term.

Where a corporation does not have a classified board, Delaware law allows the removal of a director from office, with or without cause, by the affirmative vote of the holders of a majority of the voting power of all shares entitled to vote at an election of directors. Where a corporation has a classified board, however, removal is allowed only for cause unless the corporation’s certificate of incorporation provides otherwise.

 

Under Entegris Delaware’s certificate of incorporation and bylaws, the directors of Entegris Delaware may be removed only for cause, and removal for cause may only be effected by the affirmative vote of the holders of at least 75% of the outstanding shares of capital stock of Entegris Delaware entitled to vote for directors.

  

Minnesota law allows the removal of a director from office, with or without cause, by the affirmative vote of the holders of a majority of the voting power of all shares entitled to vote at an election of directors or such higher percentage set forth in a corporation’s articles of incorporation.

 

Entegris’ bylaws provide that a vote of holders of at least 51% of the voting power of the outstanding shares is required to remove directors with or without cause, but that provision may not be enforceable because it is not in the articles of incorporation. If a director has been appointed to fill a vacancy and the stockholders have not subsequently elected directors, then the board under Minnesota law may remove that director by majority vote of those directors present at a meeting.

Cumulative Voting for Election of Directors:    Entegris Delaware’s certificate of incorporation does not provide for cumulative voting by stockholders, which means that a minority stockholder cannot be assured of electing any director.    Entegris’ articles of incorporation do not permit cumulative voting, which means that a minority stockholder cannot be assured of electing any director.
Stockholder Vote Required for Certain Extraordinary Actions:    Under Delaware law, the approval of a merger, consolidation or a sale of all or substantially all of a corporation’s assets requires the affirmative vote of holders of a majority of the voting power of the outstanding stock entitled to vote on the matter.    Under Minnesota law, the approval of a merger, share exchange or a sale of all or substantially all of a corporation’s assets requires the affirmative vote of holders of a majority of the voting power of the outstanding stock entitled to vote on the matter.
Notice of Stockholder Meetings:    Entegris Delaware’s bylaws require that written notice of meetings of stockholders, stating the place, date and hour, generally be given no less than 10 or more than 60 days before the meeting to each stockholder entitled to vote at the meeting.    Entegris’ bylaws require that notice of meetings of stockholders, stating the place, date and time, generally be given not less than 3 or more than 60 days before the meeting to each stockholder entitled to vote at the meeting.

Record Date:

   Delaware law and Entegris Delaware’s bylaws provide that the board may fix a record date in advance, not more than 60 days or less than 10 days before a stockholder meeting, to determine the stockholders entitled to notice of a stockholder meeting and to vote at the meeting.    Entegris’ bylaws provide that the board of directors may fix a record date, not more than 60 days before a stockholder meeting, to determine the stockholders entitled to notice of a stockholder meeting and to vote at the meeting.

Quorum:

   Entegris Delaware’s bylaws provide that the holders of a majority of the shares of capital stock of the corporation issued and outstanding and entitled to vote constitute a quorum.    Entegris’ bylaws provide that the holders of a majority of the voting power of Entegris’ outstanding voting shares constitute a quorum. Minnesota law and Entegris’ bylaws provide that if a quorum is present when a meeting is convened, action can be taken even if the withdrawal of stockholders originally present leaves less than what would otherwise constitute a quorum.
Stockholder Action by Written Consent:    Although Delaware law permits stockholder action by written consent without a meeting unless otherwise provided in the certificate of incorporation, Entegris Delaware’s certificate of incorporation does not permit stockholder action by written consent.    Minnesota law permits stockholder approval to be obtained by written action without a meeting only by unanimous consent of all holders of voting capital stock of the corporation.

Amendment of Charter:

   Under Delaware law, the board of directors must approve any amendment to the certificate of incorporation. The amendment must also be approved by the affirmative vote of holders of a majority of the outstanding voting stock entitled to vote on the amendment and a majority of the outstanding stock of each class of stock entitled to vote on the amendment as a class, unless a higher vote is required by the certificate of incorporation or bylaws. A class of stock is generally entitled to class-voting rights under Delaware law regardless of the provisions of the certificate of incorporation if the amendment would increase or decrease the number of authorized shares of the class, increase or decrease the par value of the shares of the class, or alter the powers, preferences or special rights of the shares of the class so as to affect that class adversely. The class vote for increases in the number of shares in the class can, however, be eliminated by the certificate of incorporation. Entegris Delaware’s certificate of incorporation provides for the elimination of such vote for increases in the number of authorized shares of preferred stock, unless the resolutions of the board of directors creating any series of preferred stock otherwise provide.   

Under Minnesota law, a resolution to amend the articles of incorporation may be made by a majority of the board of directors or by stockholders holding at least 3% of the voting power of all outstanding voting shares. An amendment to the articles must be approved by the affirmative vote of a majority of the voting power of the shares present and entitled to vote on the amendment unless a higher vote is required by the articles of incorporation.

 

Under Minnesota law, holders of each class or series of stock are entitled to class- or series-voting rights in connection with certain amendments to the articles of incorporation and certain transactions that would have the same effect as such amendments.

Entegris Stockholder Rights


     Under Entegris Delaware’s certificate of incorporation, certain changes to the certificate of incorporation must be approved by holders of at least 75% of the outstanding shares of voting stock, including amendments to the provisions relating to the number of directors, classifications of directors, removal of directors, filling vacancies on the board, calling special meetings of the stockholders and the prohibition on stockholder action by written consent in lieu of meetings.     

Amendment of Bylaws:

   Under Delaware law, the stockholders have the power to adopt, amend or repeal the bylaws. Delaware law provides that the board of directors may also adopt, amend or repeal the bylaws if such power is given to it in the certificate of incorporation. Entegris Delaware’s certificate of incorporation gives this power to the board of directors and provides that Entegris Delaware stockholders may not amend, alter or repeal the bylaws unless holders of at least 75% of the shares entitled to vote generally in the election of directors approve the amendment, alteration or repeal.   

Minnesota law provides that the power to adopt, amend or repeal a corporation’s bylaws is vested in the board of directors. The power of the board of directors is subject to the right of stockholders holding at least 3% of the voting power of the outstanding shares to propose a resolution to adopt, amend or repeal the bylaws, which must be approved by the affirmative vote of holders of a majority of the shares present and entitled to vote at a meeting or such higher percentage as is provided in the articles of incorporation. No higher percentage is provided in Entegris’ articles of incorporation, but the corporation’s bylaws purport to require the vote of holders of at least 51% of the voting power of the corporation’s outstanding voting stock to adopt, amend or repeal bylaws relating to directors.

 

Under Minnesota law, only the stockholders may adopt, amend or repeal bylaws fixing a quorum for meetings of stockholders, prescribing procedures for removing directors or filling vacancies in the board of directors or fixing the number of directors or their classifications, qualifications or terms of office.

Dividends and Repurchase of Shares:    Under Delaware law, a corporation may pay dividends out of surplus or, if there is no surplus, out of net profits for the current fiscal year or the prior fiscal year. Even if the dividends are otherwise permitted to be paid out of net profits, they may not be paid unless the amount of capital of the corporation following the payment is not less than the aggregate amount of capital represented by the outstanding stock of all classes having a preference upon the distribution of assets. A corporation may not repurchase its own shares if the capital of the corporation is impaired or if the repurchase would impair the capital of the corporation.    Under Minnesota law, a corporation may pay dividends or repurchase its own shares if the corporation will be able to pay its debts in the ordinary course of business after paying the dividends or repurchasing the shares. The ability of a corporation to pay dividends or acquire its own shares is also subject to a restriction providing that all amounts payable to any shares having a preference for that kind of distribution must have been paid.
Stockholder Rights Plan:    Entegris Delaware’s board of directors is expected to adopt a stockholder rights plan that, like Mykrolis’ plan, generally would be triggered if a person beneficially acquires 15% or more of Entegris Delaware’s common stock.    Entegris does not have a stockholder rights plan.
Dissenters’ Appraisal, Dissenters’ Rights:   

Under Delaware law, stockholders have the right to obtain a judicial appraisal of the fair value of their shares in connection with certain mergers and consolidations.

 

No appraisal rights are available to holders of shares of a class of stock that is either (a) listed on a national securities exchange or designated as a national-market-system security by the National Association of Securities Dealers or (b) held of record by more than 2,000 stockholders, unless the holders are required in the merger to accept for their shares anything other than (1) shares of the surviving corporation, (2) shares of stock of another corporation of the kind described in either (a) or (b) above, (3) cash instead of fractional shares, or (4) any combination of (1) through (3).

 

In addition, appraisal rights do not arise when a corporation is the surviving corporation in a merger and no vote of its stockholders is required to complete the merger.

  

Under Minnesota law, dissenters’ rights to a judicial determination of the fair value of their shares are available in connection with:

 

•      an amendment to the articles that materially and adversely affects the rights or preferences of shares held by the dissenting stockholder in the context of preferential, redemption, preemptive or voting rights;

 

•      a plan of merger or exchange, except that no dissenters’ rights are available to holders of shares of a class of stock that is either (a) listed on a national securities exchange or (b) designated as a national-market-system security by the National Association of Securities Dealers, unless the holders are required in the merger to accept for their shares anything other than (1) shares of the surviving corporation, (2) shares of stock of another corporation of the kind described either (a) or (b) above, (3) cash instead of fractional shares, or (4) any combination of (1) through (3).

Entegris Stockholder Rights


     Appraisal rights are not available under Delaware law in connection with a sale of all or substantially all the assets of a corporation.   

•      disposition of all or substantially all of a corporation’s property and assets other than in the usual and regular course of business (other than a disposition for cash on terms requiring pro rata distribution of the net proceeds to stockholders within one year).

 

Dissenters’ rights are not available under Minnesota law to a stockholder of (a) a surviving corporation with respect to a merger if the stockholder’s shares are not entitled to be voted on the merger and the stockholder’s shares are not canceled or exchanged in the merger or (b) a corporation that will acquire shares in a plan of exchange or a stockholder whose shares will be acquired in a plan of exchange if the stockholder was not entitled to vote on the plan of exchange and the stockholder’s shares are not exchanged.

Annual Meeting Proposals:    Entegris Delaware’s bylaws provide that at any annual meeting the only business that may be conducted (including stockholder nominations for director) is that which was brought before the meeting by the board or by any stockholder who provided notice to the corporation not less than 60 nor more than 90 days before the anniversary date of the preceding year’s meeting. If, however, the annual meeting is not held within 30 days of the anniversary date of the preceding year’s meeting, then the stockholder’s notice must be received within the earlier of 10 days after the mailing of notice or public disclosure of the meeting date.    Entegris’ bylaws have no advance notice requirements for stockholders with respect to business to be conducted at annual meetings, including stockholder nominations for directors.

Special Meetings:

   Entegris Delaware’s bylaws provide that a special meeting of stockholders may be called only by the chairman of the board, the chief executive officer or the president if there is no chief executive officer, or a majority of the directors then in office.    Minnesota law and Entegris’ bylaws provide that a special meeting of stockholders may be called at any time by the chief executive officer, the chief financial officer, by two or more directors or by stockholders holding 10% or more of the voting power of all shares entitled to vote (except that a special

          meeting called by stockholders for the purpose of considering any action to directly or indirectly facilitate or effect a business combination must be called by 25% or more of the voting power of all shares entitled to vote).
Anti-Takeover Provisions under Applicable Law:   

Delaware law provides that, if a person beneficially owns 15% or more of the stock of a publicly held corporation (an “interested stockholder”), that person (if that person was not an interested stockholder before the corporation became a publicly held corporation) may not engage in certain business-combination transactions with the corporation for a period of three years, unless one of the following three exceptions applies:

 

•      the board of directors approved the transaction that resulted in the stockholder becoming an interested stockholder or the business combination transaction before the time that the person crosses the 15% level;

 

•      upon consummation of the transaction in which the person crossed the 15% level, the person owned at least 85% of the voting stock, excluding voting stock held by officers who are also directors and certain employee stock plans; or

 

•      the business combination transaction is approved by the board of directors and by the affirmative vote of two-thirds of the outstanding voting stock that is not owned by the 15% stockholder.

  

Entegris is subject to the following provisions of Minnesota law that may have anti-takeover effects:

 

•      a provision that prohibits business-combination transactions with a stockholder for four years after the stockholder acquires 10% of the voting power of the corporation unless, before the share acquisition, the transaction or share acquisition receives approval of a majority of a committee consisting of one or more disinterested directors;

 

•      a control-share-acquisition statute, which provides that a person acquiring 20% or more of the voting power of a corporation may not vote those shares in excess of the 20% level unless and until approved by holders of (a) a majority of the voting power of the corporation’s shares, including those held by the acquiring person, and (b) a majority of the voting power of the corporation’s shares held by disinterested stockholders;

 

•      a provision that prohibits corporations from purchasing any voting shares owned for less than two years from a greater-than-5% stockholder for more than the market value of those shares, unless the transaction has been approved by a majority of the voting power of all shares entitled to vote or unless the corporation makes an offer of at least equal value per share to all holders of shares of the class or series of stock held by the greater-than-5% stockholder and to all holders of any class or series into which those securities may be converted; and

 

123


Table of Contents
    

Entegris Delaware Stockholder Rights


  

Entegris Stockholder Rights


         

•      a “fair price” provision, which provides that no person may acquire shares of a Minnesota corporation within two years following the person’s last purchase of shares in a takeover offer, unless the stockholders are given a reasonable opportunity to dispose of their shares to the person on terms substantially equivalent to those provided in the takeover offer. The provision does not apply if the acquisition is approved by a committee consisting of disinterested directors before the person acquires any shares in the takeover offer.

Stockholder Inspection Rights:    Upon compliance with certain requirements, Delaware law permits any stockholder to inspect a corporation’s stock ledger, stockholder lists and other books and records for a purpose reasonably related to the person’s interest as a stockholder.    Minnesota law permits any stockholder, beneficial owner of shares or holder of voting trust certificate of a publicly held corporation to examine and copy a corporation’s share register and other corporate records reasonably related to the person’s stated purpose upon demonstrating the stated purpose to be a proper purpose related to the person’s interest as a stockholder, beneficial owner or holder of a voting trust certificate.
Limitation of Liability of Directors and Officers:   

Entegris Delaware’s certificate of incorporation provides that, except to the extent prohibited by Delaware law, Entegris Delaware’s directors have no personal liability to either Entegris Delaware or its stockholders for monetary damages for breach of fiduciary duty. Delaware law prohibits this limitation of liability in respect of:

 

•      a breach of the director’s duty of loyalty to the corporation or its stockholders;

 

•      acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

 

•      payment of unlawful dividends or unlawful stock purchases or redemptions;

  

Entegris’ articles of incorporation provide that Entegris’ directors have no personal liability to either Entegris or its stockholders for monetary damages for breach of fiduciary duty except for the liability for the following, which are required exceptions under Minnesota law:

 

•      a breach of the director’s duty of loyalty to the corporation or its stockholders;

 

•      acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

 

•      payment of unlawful dividends or unlawful stock purchases or redemptions;

 

•      any transaction in which the director derived an improper personal benefit;

 

124

•      any transaction in which the director derived an improper personal benefit; and

 

•      any act or omission occurring before the date when the provision in the certificate of incorporation eliminating or limiting liability became effective.

  

•      certain violations of the Minnesota securities laws; and

 

•      any act or omission occurring before the date when the provision in the articles of incorporation eliminating or limiting liability became effective.

Indemnification:

   Entegris Delaware’s bylaws require indemnification of present and former directors and officers to the fullest extent permitted by law. Entegris Delaware’s bylaws also require that expenses be advanced to present and former directors in advance of final disposition of proceedings against them if they undertake to repay the amounts advanced if there is a final judicial decision that indemnification is not permitted. Entegris Delaware plans to enter into indemnification agreements with all directors and officers of Entegris Delaware and directors and officers of Entegris and Mykrolis at the time of the merger in accordance with the terms of the merger agreement.    Entegris’ bylaws require indemnification of present and former directors, officers and employees if they comply with the standards set forth in the MBCA and in the bylaws. Under Minnesota law, expenses must be advanced to present and former directors, officers and employees in advance of final disposition of proceedings against them if they affirm in writing that the statutory criteria for indemnification are satisfied and undertake to repay the amounts advanced if it is ultimately determined that the statutory criteria for indemnification are not satisfied, provided that the expenses can be advanced only if the board of directors (if a majority of the directors are disinterested), a disinterested committee of the board, special legal counsel or the stockholders determine that the facts then known would not preclude indemnification under Minnesota law.

OTHER MATTERS TO BE CONSIDERED AT THE

MYKROLIS SPECIAL MEETING IN LIEU OF ANNUAL MEETING

 

Election of Directors

 

At the Mykrolis special meeting in lieu of annual meeting, Mykrolis stockholders will be asked to vote on the election of two directors. If the merger is not consummated, each director so elected will hold office as provided in the following paragraph. If the merger is consummated, the combined company’s board of directors will be reconstituted to consist of five designees of Mykrolis and five designees of the current Entegris. The merger agreement also provides that the new board may approve an eleventh member after the effective time of the merger who is recommended by the chief executive officer and the chairman of Entegris Delaware and nominated by the nominating and governance committee of Entegris Delaware. See “Board of Directors and Management of Entegris Delaware Following the Merger.”

 

Mykrolis has a classified board of directors currently consisting of two Class I Directors, two Class II Directors and two Class III Directors. At each annual meeting of stockholders, directors in one class are elected for a full term of three years to succeed those directors whose terms are expiring. The Class I Directors have terms expiring at the 2007 Annual Meeting and the Class III Directors have terms expiring at the 2006 Annual Meeting or, in each case, upon completion of the merger, if earlier. This year, each of the two Class II Directors will stand for election to a three-year term expiring at the 2008 Annual Meeting and until his successor is duly elected and qualified, or upon completion of the merger, if earlier. The persons named in the enclosed proxy will vote to elect as directors Daniel W. Christman and Thomas O. Pyle, the Class II nominees designated by the board of directors, unless the proxy is marked otherwise. Each of the nominees has indicated his willingness to serve, if elected. However, if a nominee should be unable to serve, the shares of common stock represented by proxies may be voted for a substitute nominee designated by the board of directors. There are no family relationships between or among any officers or directors of Mykrolis.

 

Set forth below are the name and age of each nominee for election as a Class II Director and of each continuing member of the board of directors and the year of his first election as a director of Mykrolis. See “Board of Directors and Management of Entegris Delaware Following the Merger” for a description of such nominee’s principal occupation and business experience during the past five years and the names of other publicly held companies of which he serves as a director. Information with respect to the number of shares of Mykrolis common stock beneficially owned by each director, directly or indirectly, as of March 31, 2005, appears below under the heading “Ownership of Mykrolis Common Stock.”

Caldwell is set forth below.

 

Robert E. Caldwell has served as a director of Mykrolis since 2001 and as chairman of the Management Development & Compensation Committee of the board of directors from 2001 until 2004; he continues as a member of that committee. Mr. Caldwell retired from his position as vice president and general manager of the Semiconductor Division of Digital Equipment Corporation, a supplier of networked computer systems, software and services, in September 1998, a position he had held since 1990. Prior to that, Mr. Caldwell held various engineering and product management positions at Dickinson Electronics, Motorola, Inc., Mostek Corporation and Fairchild Camera & Instrument Corporation, a semiconductor manufacturer, where he served as general manager of the Gate Array Division from 1981 through 1983.

 

Board and Committee Meetings

 

The board of directors has a standing Audit & Finance Committee, which provides the opportunity for direct contact between Mykrolis’ independent registered public accounting firm and the directors. The board of directors has adopted and amended a written charter for the Audit & Finance Committee, a copy of which is posted on Mykrolis’ web site www.mykrolis.com under “Investor Relations—Governance.” The responsibilities of the Audit & Finance Committee include selection, appointment, compensation and oversight of Mykrolis’ independent registered public accounting firm as well as reviewing the scope and results of audits and reviewing Mykrolis’ internal accounting control policies and procedures. The Audit & Finance Committee held seven meetings during 2004. The current members of the Audit & Finance Committee are Messrs. Bradley, Christman and Pyle, each of whom has been determined by the board of directors to be “independent” as defined under Section 303A.02 of the New York Stock Exchange’s listing standards. The board of directors has determined that Michael A. Bradley, the Chairman of the Audit & Finance Committee, possesses the attributes of an “audit committee financial expert” as that term is defined in the rules of the Securities and Exchange Commission.

 

The board of directors also has a standing Management Development & Compensation Committee, which provides recommendations to the Board regarding Mykrolis compensation programs. The board of directors has adopted and amended a written charter for the Management Development & Compensation Committee, a copy of which is posted on Mykrolis’ web site www.mykrolis.com under “Investor Relations—Governance.” The responsibilities of the Management Development & Compensation Committee include determining the compensation of corporate officers, reviewing and recommending changes to stock option and other employee

benefit plans, reviewing the administration of such plans and reviewing Mykrolis’ management development programs and strategies. The Management Development & Compensation Committee held six meetings during 2004. The members of the Management Development & Compensation Committee are Messrs. Carns and Caldwell, each of whom has been determined by the board of directors to be “independent” as defined under Section 303A.02 of the New York Stock Exchange’s listing standards. See “Management Development & Compensation Committee Report on Executive Compensation” below.

 

The board of directors does not have a nominating committee; the functions normally performed by a nominating committee have been assigned to the Audit & Finance Committee by the board of directors. The nominating functions of the Audit & Finance Committee are set forth in the Audit & Finance Committee charter under the heading “Governance Functions.” In its nominating capacity, the Audit & Finance Committee determines the selection criteria for new directors and considers recommendations for nominee candidates from other directors, management and stockholders. Stockholders wishing to submit candidates for consideration as nominees may do so by directing an appropriate letter and resume to Peter W. Walcott, vice president, general counsel and secretary of Mykrolis, in accordance with the procedures described under “Submission of Future Stockholder Proposals” below. The Audit & Finance Committee, acting in its nominating capacity, periodically reviews the size and composition of the board of directors to determine whether the nomination of replacement or additional directors is appropriate. Identification of nominee candidates will generally rely upon acquaintances of the independent directors or management or individuals identified by third party search firms retained by the Audit & Finance Committee. The Audit & Finance Committee has established selection criteria for potential candidates as new directors. Criteria required of all director candidates include: integrity, intelligence, independence, flexibility, willing team member, willingness to speak out, and consensus driven. In addition, in order to promote a beneficial mix of perspectives, experience and expertise, the Audit & Finance Committee has established the following special criteria which would make a given candidate desirable: gender diversity, ethnic/racial diversity, geographic diversity, CEO experience, CFO/financial expert experience, industry experience and technical expertise.

 

The board of directors held nine meetings during 2004. Each director attended at least 75% of the aggregate number of meetings held, while he was a director, by the board of directors and by any committee on which he served.

 

Effective January 1, 2005, the board of directors elected Thomas O. Pyle as a non-executive chairman of the board of directors to perform the duties normally associated with that position as well as to co-ordinate communications among the directors and between stockholders and the directors. Mykrolis’ board of directors has established procedures for stockholders to communicate with the board of directors. All communications should be directed: if by mail, to Thomas O. Pyle, Chairman of the Board of Directors, Mykrolis Corporation, P.O. Box 305, Billerica, MA 01821 or if by e-mail, to chairman@mykrolis.com.

 

Members of the board of directors are encouraged to attend Annual Meetings of Stockholders. All directors attended the 2004 Annual Meeting of Stockholders.

 

Director Compensation

 

Non-employee directors are reimbursed for their out-of-pocket expenses incurred in connection with services as a director. During 2004, each non-employee director received an annual retainer of $21,000 plus $1,250 for each board or committee meeting attended. In addition, the presiding director received an annual retainer of $7,000 and any non-employee director who served as chairman of a committee of the board received an annual retainer of $3,500. Effective January 1, 2005, the directors’ cash compensation was increased as follows: annual retainer of $25,000; annual retainer for committee chairmen of $8,000 for chairman of the Audit & Finance Committee and $5,000 for the chairman of the Management Development & Compensation Committee; per-meeting fees for board of directors meetings of $2,000, and for committee meetings of $1,250. In addition, effective January 1, 2005, the board of directors elected a non-executive chairman of the board who is

 

128


Table of Contents

to receive an annual retainer of $40,000, payable quarterly, in addition to the basic director’s retainer. Effective April 25, 2005, the directors’ compensation was further amended so that each director will receive an increased annual retainer of $50,000 in lieu of all fees for attendance at meetings of the board of directors and committees thereof. Directors also receive equity compensation under the 2001 Non-Employee Director Stock Option Plan, as amended, in the form of initial and annual stock option grants. Upon initial election to the board of directors each director was granted an option to acquire 10,000 shares of Mykrolis’ common stock at the closing price on the New York Stock Exchange on the date of grant. In October 2002, the 2001 Non-Employee Director Stock Option Plan was amended prospectively to increase the size of both the initial and the annual option grants to up to 15,000 and 10,000 Mykrolis shares, respectively. All options granted under the 2001 Non-Employee Director Stock Option Plan carry an exercise price equal to 100% of fair market value on the date of grant, become exercisable in three equal annual installments beginning one year following the date of grant, and expire no later than ten years following the date of grant (subject to special provisions in the case of termination of service, retirement or death).

 

Messrs. Zadel and Argov, the only employee directors during 2004, received no compensation for their service as a director.

 

Compensation of Executive Officers

 

The following table sets forth compensation information for each chief executive officer and the four other executive officers of Mykrolis who, based on compensation from Mykrolis and its subsidiaries, were the most highly compensated for the year ended December 31, 2004. All information set forth in this table reflects compensation earned by these individuals for services with Mykrolis and its subsidiaries with respect to each of the last three fiscal years of Mykrolis. For ease of reference, we collectively refer to these executive officers throughout this section as the “named executive officers.”

Management Development & Compensation Committee Interlocks and Insider Participation

 

Until the resignation of Richard A. Aurelio on November 11, 2004, the members of the Management Development & Compensation Committee were Michael P.C. Carns, Robert E. Caldwell and Richard A. Aurelio. No member of the Management Development & Compensation Committee was at any time during fiscal year 2004 an officer or employee of Mykrolis or any subsidiary of Mykrolis, nor has any member of the Management Development & Compensation Committee had any relationship with Mykrolis requiring disclosure under Item 404 of Regulation S-K under the Securities Act of 1933.

 

During fiscal 2004, no executive officer of Mykrolis has served as a director or member of the compensation committee (or other committee serving an equivalent function) of any other entity, one of whose executive officers served as a director of or member of the Management Development & Compensation Committee of Mykrolis.

Management Development & Compensation Committee Report on Executive Compensation

 

Overview and Philosophy

 

The Management Development & Compensation Committee is comprised solely of non-employee directors of Mykrolis. The Management Development & Compensation Committee is responsible for administering Mykrolis’ executive compensation program and reviewing and making recommendations to the board of directors with respect to Mykrolis’ overall compensation policy as well as the specific compensation of executive officers and other senior management. In connection with these responsibilities, the Committee has authority to administer the Mykrolis 2001 Equity Incentive Plan and the 2003 Employment Inducement and Acquisition Stock Option Plan including recommending the grant of stock options and other awards thereunder.

 

Mykrolis’ executive compensation program is intended to attract and retain talented executives and senior management by offering competitive compensation opportunities. Mykrolis pursues a compensation philosophy

 

132


Table of Contents

that emphasizes the combination of performance-based cash compensation and stock-based compensation. We intend to provide competitive target total cash compensation (base salary plus variable incentive compensation) for competitive performance, superior total cash compensation for superior performance and reduced total cash compensation for less than competitive performance. We believe that this will foster a performance-oriented environment by tying a significant portion of each executive’s cash compensation to the achievement of objectives that are important to Mykrolis and are thus expected to enhance stockholder value. The objectives of the executive compensation policies are to:

 

    attract, retain, motivate and reward high caliber executives;

 

    foster teamwork and support the achievement of Mykrolis’ financial and strategic goals through performance based financial incentives;

 

    promote the achievement of strategic objectives which lead to long-term growth in stockholder value;

 

    encourage strong financial performance by tying variable compensation to the achievement of core financial performance metrics and leveraging incentive programs through stock–based compensation; and

 

    align the interests of executive officers with those of Mykrolis and its stockholders by making incentive compensation dependent upon Company performance.

 

Mykrolis’ executive compensation program is currently comprised of three principal components: base salary, variable incentive compensation under the Mykrolis Incentive Plan, and equity incentive in the form of stock options or stock awards granted under the Mykrolis 2001 Equity Incentive Plan.

 

Target Total Cash Compensation

 

Target total cash compensation for each executive is established based on comparable, competitive marketplace data. This data was provided by the Management Development & Compensation Committee’s third party compensation consultant. In fiscal 2004 the Committee used pay level data for positions of similar scope and responsibility to those of Mykrolis’ executives from two sources: (a) proxy analysis of thirteen public companies which are manufacturers of semiconductor components, equipment and related technologically advanced materials identified by the compensation consultant and approved by the Committee; and (b) a broad group of semiconductor and semiconductor equipment companies drawn by the committee’s compensation consultant from the SC/CHiPS Executive and Senior Management Total Compensation Survey. Target total cash compensation was determined by positioning executive compensation at approximately the median 50th percentile total direct compensation indicated by these two data sources. Specific target total cash compensation for executives was approved based upon the recommendation of the Committee’s compensation consultant.

 

Base Salary and Variable Incentive Compensation

 

Once target total cash compensation has been established for each executive, the total cash compensation is divided into a base salary portion and a variable incentive compensation portion. The variable incentive compensation portion is provided by awards under the Mykrolis Incentive Plan. Generally, the higher the level of responsibility of the executive within Mykrolis, the greater the portion of that executive’s target total cash compensation that consists of the variable incentive compensation component.

 

The variable incentive compensation component is designed to provide executive officers and other employees with a potential cash award based on the achievement of annual financial and operating objectives. A number of Company performance objectives as well as individual objectives are used; certain of Mykrolis performance objectives have been stable from year to year while others have been subject to annual reassessment. These Company performance objectives are weighted based upon their relative priority to Mykrolis. Mykrolis performance objectives, their relative weighting and the award formulae are approved in

advance by the Management Development & Compensation Committee and are designed to dovetail with operating plans approved by the Mykrolis board of directors. During 2004, Mykrolis’ performance with respect to identified objectives was measured against Mykrolis’ 2004 budget for those objectives.

 

A minimum level of Company performance is required before any award is earned under the Mykrolis Incentive Plan. During 2004, awards for executive officers and senior employees were based two-thirds on Company performance objectives and one-third on individual objectives. Other employees were eligible to receive awards equal to lesser percentages of their base salary based solely upon Mykrolis performance objectives. If a minimum level of Company performance is achieved, achievement of Mykrolis performance objectives are assessed independently so that an award can be earned with respect to one performance objective even if performance with respect to another objective does not qualify for an award. For 2004 awards under the Mykrolis Incentive Plan are calculated based upon Mykrolis’ performance during the fiscal year with respect to each performance objective using sliding scales of multipliers which increase with Mykrolis’ level of performance. Mykrolis’ absolute performance against budget was calculated separately and then combined to arrive at an overall Company performance multiplier. Achievement of individual performance objectives by executives and senior employees is assessed and a personal performance multiplier determined from that assessment. This individual performance multiplier is multiplied by the overall Company performance multiplier and applied to the weighted individual target award to determine the individual award. The sum of the corporate performance award and the individual performance award is designed to provide competitive total target cash compensation if Mykrolis achieves competitive performance.

 

For 2004 Mykrolis’ performance objectives were reported revenue versus budget, reported earnings per share versus budget and year end cash balance versus budget (subject to adjustment to generally eliminate extraordinary transactions); the weighting of these objectives were: 30% revenue growth, 40% earnings per share and 30% modified ending cash. For fiscal 2004, our executive officers were eligible to receive an incentive compensation award ranging from 40% to 70% of base salary in the event that Mykrolis achieved competitive performance with respect to the performance objectives and the individual objectives were achieved. Awards were subject to elimination of Mykrolis was not profitable for the entire year and awards to the top officers were limited to 10% of actual 2004 operating income.

 

For fiscal 2004, Mykrolis’ performance was strong, exceeding target competitive performance and justifying a variable incentive compensation award of 2.3 times the target award for competitive performance. Based upon this performance, an aggregate of $10,075,185 was earned by employees and executive officers under the Mykrolis Incentive Plan; of this amount $2,327,733 was earned by the named executive officers listed in the compensation table.

 

Equity Incentive

 

In past years Mykrolis has granted stock options annually to a group of key employees including executive officers under the Mykrolis 2001 Equity Incentive Plan; in 2004 Mykrolis replaced stock option grants with awards of restricted stock. The purpose of these grants and awards is to allow executives and employees to participate in the success of Mykrolis as measured by the stock market’s assessment of Mykrolis’ performance and thus to align their interests with those of Mykrolis stockholders. Since stock options under the 2001 Equity Incentive Plan are granted at fair market value, the recipient of an option generally is only rewarded if the market price of Mykrolis’ common stock appreciates. In addition, annual option grants and restricted stock awards carry vesting periods (or restriction periods) designed to encourage the retention of executive officers and other recipients. The number of options granted to each recipient generally is determined on the basis of the level of participation in variable incentive compensation that varies depending on the participant’s level of responsibility. While Mykrolis made stock option grants covering an aggregate of 309,500 shares under the 2003 Employment Inducement and Acquisition Stock Option Plan, during 2004, the annual equity award was changed to an award of an aggregate of 542,204 shares of restricted shares of Mykrolis common stock to executives and a group of key employees. These grants and awards amounted to approximately 2.9% of Mykrolis’ outstanding common

Table of Contents

stock. The Committee determined to make this shift to restricted stock, based upon the recommendation of its compensation consultant because the Mykrolis Management Development and Compensation Committee believes that with the commencement of so-called “fair value” accounting for stock options under SFAS 123(R), restricted stock awards represent a more efficient long term incentive compensation vehicle, delivering more value to the awardee at lower cost to Mykrolis than alternative vehicles.

 

Chief Executive Officer Compensation

 

The Management Development & Compensation Committee generally relies upon the same factors in determining the compensation of the chief executive officer as it does for the other executive officers described above, using a combination of base salary and variable incentive compensation tied to the achievement of financial performance objectives. During 2004, Mykrolis had two chief executive officers: C. William Zadel served until November 21, 2004, when he retired from that position and was replaced by Gideon Argov. Mr. Zadel’s base salary for 2004 was determined based upon the recommendation of the Committee’s compensation consultant and an evaluation of the same semiconductor industry competitive marketplace data referred to above. While this analysis indicated that Mr. Zadel’s total cash compensation was above the target median level suggested by the two data sources, this compensation level was deemed appropriate by the Mykrolis board of directors because the composite total cash compensation of the executive group as a whole was nevertheless slightly below the median level, it was viewed as a mechanism to retain Mr. Zadel’s services until a successor could be selected and based on the challenges he had met in managing Mykrolis’ operations through an extended and severe industry downturn, while completing the separation of operations from Millipore and the challenges for 2004 to establish a solid base of profitability for Mykrolis while positioning it for extraordinary future growth. During 2004, Mr. Zadel received no grant of options or award of restricted stock. Mr. Argov’s cash and equity compensation was determined by negotiation between the Committee and Mr. Argov in connection with his acceptance of the Committee’s offer of employment and is within the target 50th percentile median level of compensation from the two data sources described above. Effective November 21, 2004, Mr. Argov was awarded 50,000 shares of restricted stock in lieu of participation in the MIP for 2005 and options to acquire 450,000 shares of Mykrolis common stock.

 

Internal Revenue Code Section 162(m)

 

The Mykrolis Management Development & Compensation Committee is aware of the potential impact upon Mykrolis of Section 162(m) of the Internal Revenue Code of 1986, which prohibits public companies from deducting certain executive remuneration in excess of $1,000,000. While reserving the right of Mykrolis to offer such compensation arrangements as may be from time-to-time necessary to attract and retain top-quality management, the Committee intends generally to structure such arrangements, where feasible, so as to minimize or eliminate the impact of the limitations of Section 162(m) of the Code.

Comparative Stock Performance

 

The comparative stock performance line graph below compares the cumulative stockholder return on the common stock of Mykrolis (MYK) for the period from the commencement of trading on the New York Stock Exchange following its initial public offering, August 10, 2001, through December 31, 2004, with the cumulative total return on (i) the Total Return Index for The New York Stock Exchange (the “NYSE Composite Index”) through December 31, 2002, (ii) the Philadelphia Semiconductor Index (SOX), which is a published industry index, through December 31, 2004, and (iii) the Standard & Poor’s 500 Index through December 31, 2004. The SOX contains 16 companies in the semiconductor and semiconductor equipment industries. The cumulative total return computations set forth in the performance graph assume the investment of $100 in Mykrolis’ common stock, the NYSE Composite Index, the Standard & Poor’s 500 Index and the SOX Index on August 10, 2001. Since the NYSE Composite Index was changed in 2003 to exclude closed end funds, derivatives and limited partnerships in order to avoid double counting stocks held in the portfolios of those entities and since recalculated data for the NYSE Composite Index for prior periods is not available, Mykrolis has excluded the restructured NYSE Composite Index for 2003 and 2004 and added the Standard & Poor’s 500 Index as a substitute broad market index. Prior to August 10, 2001, Mykrolis’ common stock was not registered under the Securities Act of 1933.

Report of the Audit & Finance Committee

 

The Audit & Finance Committee is comprised of three members and acts under a written charter adopted by the board of directors. The members of the Audit & Finance Committee are independent directors, as defined in the Audit & Finance Committee Charter and in Sections 303A.01 of the New York Stock Exchange’s listing standards.

 

The Audit & Finance Committee reviewed Mykrolis’ audited financial statements for the fiscal year ended December 31, 2004 and discussed these financial statements with Mykrolis’ management. Management is responsible for Mykrolis’ internal controls and the financial reporting process. Management represented to the Audit & Finance Committee that Mykrolis’ financial statements had been prepared in accordance with accounting principles generally accepted in the United States. Mykrolis’ independent registered public accounting firm is responsible for performing an audit of Mykrolis’ financial statements and financial statement schedules, management’s assessment of the effectiveness of internal control over financial reporting and the effectiveness of internal control over financial reporting in accordance with standards of the Public Company Accounting Oversight Board (United States) and to issue a report based on those audits. More specifically, the Audit & Finance Committee reviews, evaluates, and discusses with Mykrolis’ management and with the independent registered public accounting firm, the following matters:

 

    the plan for, and the independent registered public accounting firm’s report on, each audit of Mykrolis’ financial statements and management’s assessment of the effectiveness of internal control over financial reporting and the effectiveness of internal control over financial reporting;

 

    Mykrolis’ financial disclosure documents, including all financial statements and reports filed with the Securities and Exchange Commission or sent to stockholders;

 

    changes in Mykrolis’ accounting practices, principles, controls or methodologies; significant developments or changes in accounting rules applicable to Mykrolis; and

 

    the adequacy of Mykrolis’ internal controls and accounting, financial and auditing personnel and the areas of risk that could impact Mykrolis’ business.

 

The Audit & Finance Committee also reviewed and discussed the audited financial statements and the matters required by Statement on Auditing Standards 61 (Communication with Audit Committees) with PricewaterhouseCoopers LLP, Mykrolis’ independent registered public accounting firm. SAS 61 requires Mykrolis’ independent registered public accounting firm to discuss with Mykrolis’ Audit & Finance Committee, among other things, the following:

 

    methods to account for significant unusual transactions;

 

    the effect of significant accounting policies in controversial or emerging areas for which there is a lack of authoritative guidance or consensus;

 

    the process used by management in formulating particularly sensitive accounting estimates and the basis for the auditors’ conclusions regarding the reasonableness of those estimates; and

 

    disagreements with management over the application of accounting principles, the basis for management’s accounting estimates and the disclosures in the financial statements.

 

Mykrolis’ independent registered public accounting firm also provided the Audit & Finance Committee with the written disclosures and the letter required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees). Independence Standards Board Standard No. 1 requires auditors annually to disclose in writing all relationships that in the auditor’s professional opinion may reasonably be thought to bear on independence, confirm their perceived independence and engage in a discussion of independence. The Audit & Finance Committee discussed with the independent registered public accounting firm the matters disclosed in this letter and their independence from Mykrolis. The Audit & Finance Committee also

Table of Contents

considered whether the independent registered public accounting firm’s provision of the other, non-audit related services to Mykrolis which are referred to under the heading “Accountants” is compatible with maintaining such auditors’ independence.

 

Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the Audit & Finance Committee recommended to Mykrolis’ board of directors that the audited financial statements be included in Mykrolis’ Annual Report on Form 10-K for the year ended December 31, 2004.

 

In performing all of these functions, the Audit & Finance Committee acts only in an oversight capacity. The members of the Audit & Finance Committee have necessarily relied on the information, opinions, reports and statements presented to them by Mykrolis management, which has the primary responsibility for financial statements and reports. The members of the Audit & Finance Committee have also relied on the work and assurances of Mykrolis’ independent accountants, who in their report express an opinion on Mykrolis’ annual financial statements. Accordingly, while the Audit & Finance Committee has recommended to the Mykrolis board of directors that the audited financial statements be included in Mykrolis’ Annual Report of Form 10-K as described above, the foregoing oversight procedures do not assure that management has maintained adequate financial reporting processes and controls, that the financial statements are accurate, or that the audit would detect all inaccuracies or flaws in Mykrolis’ financial statements. The information set forth in this report of the Audit & Finance Committee is not “soliciting material,” deemed to be “filed” with the Securities and Exchange Commission and is not incorporated by reference into any filings of Mykrolis under the Securities Exchange Act of 1934, irrespective of any general incorporation language contained in any such filing.

In connection with their examination of and report upon Mykrolis’ financial statements, on management’s assessment of the effectiveness of the company’s internal control over financial reporting, and on the effectiveness of the internal control over financial reporting for 2004, PricewaterhouseCoopers LLP also read Mykrolis’ Annual Report on Form 10-K and 10-K/A and performed a review of its quarterly financial statements included in the quarterly reports on Form 10-Q filed with the Securities and Exchange Commission.

Table of Contents

The fees for Audit Related services as of the years ended December 31, 2004 and 2003 were for assurance and related services with respect to the employee benefit plan audit, Sarbanes-Oxley Act of 2002 advisory services and audit procedures related to the assets acquired and the liabilities assumed pursuant to an acquisition.

 

The fees for Tax services for the years ended December 31, 2004 and 2003, respectively, were for services related to tax compliance, tax planning and tax advice.

 

Effective October 1, 2002, Mykrolis’ board of directors has amended the charter of the Audit & Finance Committee to require the pre-approval of all non-audit services before any such non-audit services are performed for Mykrolis. The amended charter of the Audit & Finance Committee is posted on Mykrolis’ web site www.mykrolis.com under “Investor Relations—Governance.” The Audit & Finance Committee adopted pre-approval policies and procedures with respect to audit and permissible non audit services (“Services”) effective June 19, 2003. Under this policy Services must receive either a general pre-approval or a specific pre-approval by the Audit & Finance Committee. The grant of a general pre-approval of Services is limited to identified Services that have been determined not to impair the independence of the independent auditor and must include a maximum fee level for the Services approved. A request for specific pre-approval must include detailed information concerning the scope of the Services and the fees to be charged. The policy also provides for a special delegation of pre-approval authority to the chairman of the Audit & Finance Committee where the commencement of Services is required prior to the next scheduled meeting of the Audit & Finance Committee and it is impractical to schedule a special meeting; any such pre-approval by the chairman is subject to review by the full Committee. All of the fees listed for 2004 in the table above received pre-approval by the Audit & Finance Committee.

 

Shares Available for Awards under Equity Incentive Plans

HOUSEHOLDING OF PROXY MATERIALS

 

Securities Exchange Commission rules permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for stockholders and cost savings for companies. Entegris, Mykrolis and some brokers household proxy materials, delivering a single proxy statement to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from Entegris, Mykrolis or your broker that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement, or if you are receiving multiple copies of the proxy statement and wish to receive only one, please notify your broker if your shares are held in a brokerage account or Entegris or Mykrolis (as applicable) if you hold registered shares. You can also request prompt delivery of a copy of this joint proxy statement/prospectus. See “Where You Can Find More Information” beginning on page [    ] for the appropriate contact information for Entegris and Mykrolis.

RECITALS

 

A. The Board of Directors of each of Entegris, Eagle Delaware and Mykrolis deems it advisable and in the best interests of the respective corporation and its shareholders that Entegris and Mykrolis combine in a merger of equals to advance the long-term business interests of Entegris and Mykrolis and each has approved this Agreement and the transactions contemplated hereby.

1.01. Merger. At the Effective Time (as defined in Section 1.02) and immediately following the Reincorporation Merger Effective Time, and in accordance with the terms of this Agreement and the General Corporation Law of the State of Delaware (the “Delaware Corporation Law”), Mykrolis shall be merged with and into Eagle Delaware, and the separate corporate existence of Mykrolis shall thereupon cease. Eagle Delaware shall be the surviving corporation in the Merger (sometimes referred to as the “Surviving Corporation”) and shall continue to be governed by the Delaware Corporation Law. The Merger shall have the other effects set forth in the applicable provisions of the Delaware Corporation Law.

 

1.02. Effective Time of the Merger. The Merger shall become effective (the “Effective Time”) upon the filing of a certificate of merger (the “Certificate of Merger”) with the Delaware Secretary of State in such form as is required by, and executed in accordance with, the relevant provisions of the Delaware Corporation Law and the terms of this Agreement or at such later date or time as Eagle Delaware and Mykrolis agree and specify in the Certificate of Merger. The filing of the Certificate of Merger shall be made immediately following the Reincorporation Merger Effective Time and as soon as practicable, but no more than three business days (unless Entegris and Mykrolis shall otherwise agree) following the later of (a) the receipt of the respective votes of the shareholders of Entegris and the stockholders of Mykrolis as contemplated by Section 6.04, and (b) the satisfaction or waiver (to the extent waivable under Article VII) of all conditions to the consummation of the Merger set forth in Article VII (other than the delivery of an officers’ certificate required by Sections 7.02(a), 7.02(b) and 7.02(c) and Sections 7.03(a), 7.03(b) and 7.03(c) and the delivery of the legal opinions required by Sections 7.02(d) and 7.03(d) so long as such conditions are satisfied or waived at the Closing (as defined in Section 3.01)).

Incorporation and Bylaws of the Surviving Corporation. The parties agree that, and agree to take all action in order that, immediately prior to the Effective Time, the Certificate of Incorporation and Bylaws of Eagle Delaware shall be in the forms attached hereto as Exhibits B and C, respectively, unless and to the extent the parties agree to changes therein (in which case the parties agree to cause the Certificate of Incorporation and Bylaws of Eagle Delaware to be in such forms, with such changes as are agreed upon by the parties, immediately prior to the Effective Time); provided, however, if any provision of such Certificate of Incorporation and Bylaws (i) is required to be submitted separately to shareholders for approval at the time of their approval of the Merger and (ii) does not receive the approval of such shareholders, then the Certificate of Incorporation and Bylaws of Eagle Delaware as in effect immediately prior to the Effective Time shall not include any such provision.

ARTICLE II

CONVERSION OF SHARES

 

2.01. Conversion of Shares. At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof:

 

(a) Each share of Common Stock of Mykrolis, par value $.01 per share the “Mykrolis Common Stock”), issued and outstanding immediately before the Effective Time (other than shares of Mykrolis Common Stock held of record by Eagle Delaware) shall be converted into the right to receive 1.39 fully paid and nonassessable shares (the “Merger Consideration”) of Eagle Delaware Common Stock, subject to Section 2.05.

 

(b) Each share of Eagle Delaware Common Stock issued and outstanding immediately before the Effective Time shall remain outstanding and each certificate formerly representing such shares of Eagle Delaware Common Stock (including certificates formerly representing shares of Entegris Common Stock that have not been surrendered in connection with the Reincorporation Merger for certificates representing shares of Eagle Delaware Common Stock) shall evidence ownership and represent the same number of shares of common stock of the Surviving Corporation (referred to herein as “Eagle Delaware Common Stock”).

 

2.02. Effect of Conversion on Shares of Mykrolis Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, all shares of Mykrolis Common Stock issued and outstanding immediately prior to the Effective Time, will cease to exist and will cease to be outstanding as a result of their conversion pursuant to Section 2.01, and each holder of a certificate that immediately prior to the Effective Time represented any such shares of Mykrolis Common Stock (a “Certificate”) will thereafter cease to have any rights with respect to such shares of Mykrolis Common Stock, except the right to receive the Merger Consideration, any cash in lieu of fractional shares of Eagle Delaware Common Stock to be issued in consideration therefor pursuant to Section 2.05, and any dividends or other distributions payable pursuant to Section 2.06(d), in each case in accordance with this Article II, upon surrender of such Certificate.

 

2.03. Cancelation of Shares of Mykrolis Common Stock Held by Eagle Delaware and Subsidiaries. At the Effective Time, each share of Mykrolis Common Stock held of record by Eagle Delaware immediately prior to the Effective Time will, by virtue of the Merger, cease to exist and cease to be outstanding and will be canceled and no stock of Eagle Delaware or other consideration shall be delivered in exchange therefor.

 

2.04. Stock Options.

A-3


Table of Contents

2.05. Fractional Shares. No fractional shares of Eagle Delaware Common Stock shall be issued in the Merger. All fractional shares of Eagle Delaware Common Stock to which a holder of Mykrolis Common Stock would otherwise be entitled at the Effective Time shall be aggregated. If a fractional share would otherwise result from this aggregation, the stockholder shall be entitled upon the surrender of the stockholder’s Certificate(s) to receive from Eagle Delaware an amount in cash in lieu of the fractional share, based on the per-share closing sale price of Entegris Common Stock or Eagle Delaware Common Stock, as the case may be, on the NASDAQ National Market (“NASDAQ”) on the trading day immediately preceding the Effective Time. Eagle Delaware will make available to the Exchange Agent the cash necessary to pay for fractional shares.

 

2.06. Exchange of Certificates.

 

(a) Prior to the Effective Time, Eagle Delaware shall authorize Wells Fargo Bank, N.A., or such other firm as is reasonably acceptable to Mykrolis, to serve as exchange agent hereunder (the “Exchange Agent”) pursuant to an agreement reasonably acceptable to Mykrolis. At or immediately following the Effective Time, Eagle Delaware shall cause to be deposited in trust with the Exchange Agent, for the benefit of the holders of Mykrolis Common Stock, certificates representing the number of whole shares of Eagle Delaware Common Stock to which the holders of Mykrolis Common Stock are entitled under this Article II, and shall agree in writing with the Exchange Agent to deposit in trust with the Exchange Agent as needed cash sufficient to pay for fractional shares in accordance with Section 2.05 (such cash amounts and certificates are referred to herein collectively as the “Exchange Fund”). The Exchange Agent shall, pursuant to irrevocable instructions received from Eagle Delaware, deliver the number of shares of Eagle Delaware Common Stock and pay the amounts of cash provided for in Sections 2.01 and 2.05 out of the Exchange Fund. Additional amounts of cash, if any, needed from time to time by the Exchange Agent to make payments for fractional shares shall be provided by Eagle Delaware and shall become part of the Exchange Fund. The Exchange Fund may not be used for any other purpose, except as provided in this Agreement, or as otherwise agreed by Mykrolis and Eagle Delaware before the Effective Time. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Eagle Delaware. Any interest and other income resulting from such investments will be paid to Eagle Delaware.

 

(b) As soon as practicable after the Effective Time, the Exchange Agent shall mail and otherwise make available to each record holder (other than Eagle Delaware or any direct or indirect wholly owned Subsidiary of Eagle Delaware) who, as of the Effective Time, was a holder of a Certificate a letter of transmittal and instructions for use in effecting the surrender of the Certificate for payment therefor and conversion thereof. Delivery shall be effected, and risk of loss and title to the Certificate shall pass, only upon proper delivery of the Certificate to the Exchange Agent and the letter of transmittal shall so reflect.

 

(c) Upon surrender to the Exchange Agent of a Certificate representing shares of Mykrolis Common Stock, together with the letter of transmittal duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor (i) one or more certificates as requested by the holder (properly issued, executed, and countersigned, as appropriate) representing the number of whole shares of Eagle Delaware Common Stock to which that holder of Mykrolis Common Stock is entitled pursuant to the provisions of Section 2.01, and (ii) as to any fractional share, a check representing the cash consideration to which the holder is entitled under Section 2.05, and the Certificate so surrendered shall be canceled. No interest will be paid or accrued on any cash payable for fractional shares upon surrender of a Certificate. Eagle Delaware shall pay any transfer or other taxes required by reason of the issuance of a certificate representing shares of Eagle Delaware Common Stock if the certificate is issued in the name of the person in whose name the Certificate surrendered in exchange therefor is registered; provided, however, that Eagle Delaware shall not pay any transfer or other tax if payment of any such tax by Eagle Delaware would cause the Merger to fail to qualify as a tax-free reorganization under the Code. If any portion of the applicable Merger Consideration to be received pursuant to this Article II upon exchange of a Certificate is to be issued or paid to a person other than the person in whose name the Certificate surrendered in exchange therefor is registered, it shall be a condition of issuance and payment that the Certificate so surrendered shall be properly endorsed or otherwise in proper form for transfer and that the person requesting the exchange shall pay in advance any

 

A-4


Table of Contents

transfer or other taxes required by reason of the issuance of the applicable Merger Consideration to such other person, or establish to the satisfaction of the Exchange Agent that the tax has been paid or that no tax is applicable.

 

(d) From the Effective Time until surrender in accordance with this Section 2.06, each Certificate (other than any Certificates representing shares held of record by Eagle Delaware) shall be deemed, for all corporate purposes other than the payment of dividends or other distributions, to evidence the ownership of the applicable Merger Consideration into which those shares of Mykrolis Common Stock shall have been converted. No dividends or other distributions that are otherwise payable with respect to the applicable Merger Consideration will be paid to persons entitled to receive the applicable Merger Consideration until they surrender their Certificates. Subject to the effect of applicable abandoned property, escheat, and similar laws, promptly after surrender of a Certificate, there shall be paid to the person in whose name the applicable Merger Consideration is issued any dividends or other distributions on such applicable Merger Consideration that shall have a record date on or after the Effective Time and before surrender, provided that if the payment date for any dividend or other distribution is after the date of surrender, the payment shall be made on the payment date. Persons entitled to receive dividends or other distributions shall not be entitled to receive interest on them. Eagle Delaware shall make available to the Exchange Agent from time to time the cash necessary to make payments of dividends or other distributions on Eagle Delaware Common Stock and any such cash shall become part of the Exchange Fund.

 

(e) In the case of any lost, stolen, or destroyed Certificate, the holder thereof may be required, as a condition precedent to the delivery to the holder of the consideration described in Section 2.01 and 2.05, to deliver to Eagle Delaware a written indemnity agreement in form and substance reasonably acceptable to Eagle Delaware and, if reasonably deemed advisable by Eagle Delaware, a bond in such reasonable sum as Eagle Delaware may direct as indemnity against any claim that may be made against the Exchange Agent, the Surviving Corporation or Mykrolis with respect to the Certificate alleged to have been lost, stolen, or destroyed.

 

(f) After the Effective Time, there shall be no transfers on the stock transfer books of the Surviving Corporation or Mykrolis of the shares of Mykrolis Common Stock that were outstanding immediately before the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for transfer, they shall be canceled and exchanged for the consideration described in Sections 2.01 and 2.05. After the Effective Time, Eagle Delaware shall cause the shares of Mykrolis Common Stock to be delisted from New York Stock Exchange (the “NYSE”).

 

(g) Any portion of the Exchange Fund that remains unclaimed by the stockholders of Mykrolis one year after the Effective Time shall be returned to Eagle Delaware, upon demand, and any holder who has not complied with this Section 2.06 shall thereafter look only to Eagle Delaware, and (subject to abandoned property, escheat, or similar laws) only as a general creditor thereof, for issuance of the applicable Merger Consideration and other consideration to which the holder is entitled hereunder; provided, however, that to the fullest extent permitted by law, none of the Exchange Agent, Mykrolis, or the Surviving Corporation shall be liable to a holder of shares of Mykrolis Common Stock for any amount required to be paid to a public official under any applicable abandoned property, escheat, or similar law. If any Certificates shall not have been surrendered prior to seven years after the Effective Time, or immediately prior to such earlier date on which any shares of Eagle Delaware Common Stock, any cash in lieu of fractional shares of Eagle Delaware Common Stock or any dividends or other distributions with respect to Eagle Delaware Common Stock issuable in respect of such Certificate would otherwise escheat to or become the property of any Governmental Body, any such shares, cash, dividends or distributions in respect of such Certificate shall, to the extent permitted by applicable Law, become the property of Eagle Delaware, free and clear of all claims or interest of any person previously entitled thereto.

 

2.07. Adjustment to Merger Consideration. The applicable Merger Consideration shall be appropriately adjusted to reflect any stock split, stock dividend, recapitalization, reorganization, reclassification, exchange, subdivision, combination of, or other similar change in Entegris Common Stock, Eagle Delaware Common Stock

 

A-5


Table of Contents

or Mykrolis Common Stock after the date of this Agreement and prior to the Effective Time to provide to holders of Mykrolis Common Stock the same economic effect and percentage ownership of Eagle Delaware Common Stock as contemplated by this Agreement prior to such change in Entegris Common Stock, Eagle Delaware Common Stock or Mykrolis Common Stock; provided that the foregoing shall not permit Mykrolis or Entegris to take any action that is prohibited under this Agreement.

 

2.08. Withholding Rights. The Surviving Corporation or the Exchange Agent, as the case may be, shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any person such amounts, if any, as it is required to deduct and withhold with respect to the making of such payments under the Code, or any provisions of state, local or foreign tax Law. To the extent that amounts are withheld by the Surviving Corporation or the Exchange Agent, as the case may be, such amounts withheld shall be treated for purpose of this Agreement as having been paid to such person in respect of which such deduction and withholding was made by the Surviving Corporation or the Exchange Agent, as the case may be.

 

ARTICLE III

3.01. Generally. Subject to the provisions of Article VII, the closing (the “Closing”) of the transactions contemplated hereby shall occur at 10:00 a.m., Minneapolis, Minnesota time, two (2) business days following the special meetings of the shareholders of Entegris and of the stockholders of Mykrolis to be called under Section 6.04, or at such other date or time as Entegris and Mykrolis may mutually agree (the “Closing Date”).

ARTICLE IV

REPRESENTATIONS AND WARRANTIES

 

As used with respect to Mykrolis or Entegris, as the case may be, the term “Material Adverse Effect” means (i) any change or effect, individually or in the aggregate, that has or is reasonably likely to have a material adverse effect on the business, operations, results of operations, properties or financial condition of the party and its Subsidiaries taken as a whole, other than changes or effects (A) caused by changes in general economic or securities markets conditions, (B) that affect the business in which such party and its Subsidiaries operate in general and which do not have a materially disproportionate effect on such party and its Subsidiaries, (C) resulting from acts of terrorism or war (whether or not declared), (D) resulting from the announcement or proposed consummation of this Agreement and the transactions contemplated hereby, (E) resulting from compliance with the terms and conditions of this Agreement, or (F) in the market price or trading volume of the party’s common stock, or (ii) a material impairment on the ability of the party and its Subsidiaries to consummate the transactions contemplated by this Agreement.

 

4.01. Representations and Warranties of Mykrolis. Except as otherwise set forth in the disclosure schedule delivered by Mykrolis to Entegris concurrently with the execution of this Agreement (the “Mykrolis Disclosure Schedule”), Mykrolis represents and warrants to Entegris and Eagle Delaware as follows:

 

(a) Organization, Standing, Qualification. Mykrolis is a corporation and each of its Subsidiaries is a corporation or limited liability company (as identified in the Mykrolis Disclosure Schedule) duly organized,

 

A-6


Table of Contents

validly existing, and in good standing under the laws of the jurisdiction of its organization (as identified in the Mykrolis Disclosure Schedule) and has the requisite corporate or limited liability company, as applicable, power and authority to own, lease, and operate its properties and assets and to carry on its business as it is now being conducted. Each of Mykrolis and its Subsidiaries is duly qualified or licensed as a foreign corporation or limited liability company to do business, and is in good standing, in each jurisdiction where the character of the properties owned, operated, or leased by it, or the nature of its business, makes such qualification or licensing necessary, except those jurisdictions where failure to be so qualified, licensed, or in good standing would not be reasonably likely to have a Material Adverse Effect on Mykrolis. Complete and correct copies of the Articles or Certificate of Incorporation and Bylaws or similar charter or organizational documents of Mykrolis and each of its Subsidiaries have been made available to Entegris.

 

(b) Capitalization. The authorized capital stock of Mykrolis consists solely of the following: (i) 250,000,000 shares of Mykrolis Common Stock, of which, as of February 1, 2005, 41,961,602 shares were issued and outstanding; and (ii) 5,000,000 shares of Preferred Stock, $.01 par value per share (the “Mykrolis Preferred Stock”), of which, as of the date of this Agreement, none is issued and outstanding.

(s) Ownership of Entegris Common Stock. As of the date of this Agreement, neither Mykrolis nor, to the knowledge of Mykrolis, any of Mykrolis’ affiliates or associates (as such terms are defined under the Exchange Act) (i) beneficially owns, directly or indirectly, or (ii) is party to any agreement, arrangement, or understanding for the purpose of acquiring, holding, voting, or disposing of, in the case of either clause (i) or (ii), shares of Entegris Common Stock.

 

(t) Transactions with Affiliates.

Certain Relationship or Related Transaction pursuant to Statement of Financial Accounting Standards No. 57 or Item 404 of Regulation S-K of the SEC that has not been so reported in the Mykrolis SEC Reports.

 

(u) Disclosure Controls and Procedures. Since August 14, 2003, Mykrolis and each of its Subsidiaries has had in place “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange Act) reasonably designed and maintained to ensure that all information (both financial and non-financial) required to be disclosed by Mykrolis in the reports that it files or submits to the SEC under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to Mykrolis’ management as appropriate to allow timely decisions regarding required disclosure and to make the certifications of the chief executive officer and chief financial officer of Mykrolis required under the Exchange Act with respect to such reports. Mykrolis maintains internal accounting controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(w) Properties and Assets.

 

(i) Mykrolis or a Subsidiary of Mykrolis has good and valid (and, in the case of real property, fee simple) title to, or a valid leasehold interest in, all the real and tangible properties and assets which it purports to own or lease, including all the properties and assets reflected in the Mykrolis Balance Sheet (except for personal property sold since the date of the Mykrolis Balance Sheet in the ordinary course of business consistent with past practice). All properties and assets reflected in the Mykrolis Balance Sheet are free and clear of all Liens, except for Liens reflected on the Mykrolis Balance Sheet and Liens for current taxes not yet due and other Liens, other than for borrowed money, that do not materially impair the use or operation of the property or assets subject thereto.

 

(ii) Section 4.01(w) of the Mykrolis Disclosure Schedule sets forth a true, complete and correct list of all real property owned by Mykrolis or its Subsidiaries and the location of such premises. All material real property leases, licenses or other occupancy agreements to which Mykrolis or a Subsidiary of Mykrolis is a party or for which it is obligated (whether as lessor or tenant) (collectively, the “Mykrolis Real Property Leases”) are either filed as exhibits to the Mykrolis SEC Reports filed with the SEC prior to the date hereof or complete copies thereof have been delivered to or made available to Entegris. Section 4.01(w) of the Mykrolis Disclosure Schedule lists all Mykrolis Real Property Leases other than the Mykrolis Real Property Leases which are listed as an exhibit to Mykrolis’ most recent annual report on Form 10-K or a subsequent quarterly report on Form 10-Q.

 

(iii) Each Mykrolis Real Property Lease is in full force and effect, unless the failure of any Mykrolis Real Property Lease to be in full force and effect would not be reasonably likely to have a Material Adverse Effect on Mykrolis. Neither Mykrolis nor any of its Subsidiaries, nor to the knowledge of Mykrolis, any other party is in breach of or in default under any Mykrolis Real Property Lease, except for breaches or defaults which would not be reasonably likely to have a Material Adverse Effect on Mykrolis.

Since August 14, 2003, Entegris and each of its Subsidiaries has had in place “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange Act) reasonably designed and maintained to ensure that all information (both financial and non-financial) required to be disclosed by Entegris in the reports that it files or submits to the SEC under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to Entegris’ management as appropriate to allow timely decisions regarding required disclosure and to make the certifications of the chief executive officer and chief financial officer of Entegris required under the Exchange Act with respect to such reports. Entegris maintains internal accounting controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific

All properties and assets reflected in the Entegris Balance Sheet are free and clear of all Liens, except for Liens reflected on the Entegris Balance Sheet and Liens for current taxes not yet due and other Liens, other than for borrowed money, that do not materially impair the use or operation of the property or assets subject thereto.

Section 4.02(v) of the Entegris Disclosure Schedule lists all Entegris Real Property Leases other than the Entegris Real Property Leases which are listed as an exhibit to Entegris’ most recent annual report on Form 10-K or a subsequent quarterly report on Form 10-Q.

 

(iii) Each Entegris Real Property Lease is in full force and effect, unless the failure of any Entegris Real Property Lease to be in full force and effect would not be reasonably likely to have a Material Adverse Effect on Entegris. Neither Entegris nor any of its Subsidiaries, nor to the knowledge of Entegris, any other party is in breach of or in default under any Entegris Real Property Lease, except for breaches or defaults which would not be reasonably likely to have a Material Adverse Effect on Entegris.

ARTICLE VI

ADDITIONAL COVENANTS

 

6.01. No Solicitation.

 

(a) Except as set forth in Section 6.01 of the Mykrolis Disclosure Schedule, from the date of this Agreement until the earlier of the Effective Time or the termination of this Agreement, each of Entegris and Mykrolis (each an “Applicable Party”) shall not and shall not authorize or permit any Subsidiary, officer, director, financial adviser, representative, or agent of it or its Subsidiaries to, directly or indirectly:

 

(i) solicit, seek, initiate, or knowingly encourage any inquiries or proposals that constitute, or would be reasonably likely to lead to, a proposal or offer for (A) a merger, consolidation, or business combination involving the Applicable Party or any of its Subsidiaries (other than a merger of a wholly owned Subsidiary of an Applicable Party into the Applicable Party or another of its wholly owned Subsidiaries), (B) a sale of assets representing an amount equal to or greater than 25% of the consolidated assets of the Applicable Party and its Subsidiaries taken as a whole (other than the sale or other disposition of inventory or obsolete equipment in the ordinary course of business consistent with past practice), (C) a sale of shares of capital stock of the Applicable Party or any of its Subsidiaries (including without limitation by way of a tender offer or exchange offer) that would result in any person or group beneficially owning 10% or more of any class or series of equity securities of the Applicable Party or any of its Subsidiaries or any similar transaction involving the Applicable Party or any of its Subsidiaries, other than the transactions required by this Agreement, or (D) the consummation of any other transaction or the entering into of any other agreement or arrangement with respect to any other transaction, the effect of which would have the same result as the occurrence of the preceding clauses (A), (B), or (C) (any of the foregoing inquiries or proposals, other than those that relate to matters set forth in Section 6.01 of the Mykrolis Disclosure Schedule, being referred to in this Agreement as a “Third Party Acquisition Proposal”);

 

(ii) engage in discussions or negotiations or enter into any agreement with any person or group other than the other Applicable Party or its affiliates (a “Third Party”) concerning any Third Party Acquisition Proposal, or provide any non-public information regarding, or afford access to the properties, books, records, or personnel of, the Applicable Party or any of its Subsidiaries, to any Third Party that is considering making, or has made, any Third Party Acquisition Proposal; or

(iii) agree to or recommend any Third Party Acquisition Proposal;

 

provided, however, that, at any time prior to the time Shareholders’ Approval with respect to the Applicable Party is obtained and if the Applicable Party is not otherwise in material breach of its obligations under this Section 6.01, nothing contained in this Section 6.01 shall prevent the Applicable Party from furnishing non-public information pursuant to a confidentiality agreement at least as favorable to the Applicable Party as the Confidentiality Agreements (as defined in Section 6.13) or affording access to the properties, books, records, and personnel of the Applicable Party or any of its Subsidiaries to, or entering into discussions or negotiations with, any Third Party in connection with a Third Party Acquisition Proposal by such Third Party or recommending any Third Party Acquisition Proposal pursuant to clause (iii) hereof if and only to the extent the Board of Directors of the Applicable Party, in the exercise of its fiduciary duties, determines in good faith by a majority vote (after consultation with its financial and legal advisers) that such Third Party Acquisition Proposal is reasonably likely to result in a Superior Proposal (as hereinafter defined). For purposes of this Agreement, “Superior Proposal” means a Third Party Acquisition Proposal (except that all references to “10% or more” or “25%” in the definition of Third Party Acquisition Proposal shall be deemed to be references to “a majority”) that was not solicited in violation of this Agreement and that, in the good faith judgment of the Board of Directors of the Applicable Party, taking into account, to the extent deemed appropriate by such Board of Directors, the various legal, financial, and regulatory aspects of the Third Party Acquisition Proposal and the person or group making such proposal, (A) if accepted, is reasonably likely to be consummated, and (B) if consummated, is reasonably likely to result in a transaction that is more favorable to the Applicable Party shareholders (in their capacity as shareholders), from a financial point of view, than the transactions contemplated by this Agreement.

(c) Each of Entegris and Mykrolis agrees not to release any third party from, or waive any provision of, any confidentiality or standstill agreement to which it is a party, unless the Board of Directors thereof, in the exercise of its fiduciary duties, determines in good faith by a majority vote (after consultation with its financial and legal advisers) that such action is required. Notwithstanding anything stated in this Section 6.01(c), neither Entegris nor Mykrolis need refuse a request from any person who has signed a standstill agreement with such party to make a Third Party Acquisition Proposal to the Chief Executive Officer or the Board of Directors thereof if the Board of Directors determines in good faith by a majority vote, in the exercise of its fiduciary duties, after consultation with its legal counsel, that such action is required.

 

(d) Each of Entegris and Mykrolis will notify the other promptly (but in no event later than 24 hours) after receipt by it (or any of its advisers) of any request (other than in the ordinary course of business and not related to a Third Party Acquisition Proposal) for non-public information relating to it or any of its Subsidiaries or for access to its properties, books, or records or any of its Subsidiaries by any person who is known to be considering making, or has made, a Third Party Acquisition Proposal or of an inquiry from a third party seeking to have discussions or negotiations relating to, or make, a possible Third Party Acquisition Proposal. Such notice shall be provided orally and in writing and shall identify the terms and conditions of any such Third Party Acquisition Proposal, indication, or request, including the identify of the party making the Third Party Acquisition Proposal, indication, or request and shall be accompanied by copies of all agreements or proposed agreements related thereto. Each Applicable Party shall keep the other reasonably informed, on a prompt basis (but in any event no later than 24 hours following any written correspondence from any person known to be contemplating a Third Party Acquisition Proposal), of the status and details of any such Third Party Acquisition Proposal, indication, or request and shall provide such other party with copies of all agreements and proposed agreements related to such Third Party Acquisition Proposal.

 

(e) Each of Entegris and Mykrolis shall, and shall cause each of its Subsidiaries and the directors, employees, financial advisers, representatives, and other agents of it and its Subsidiaries to, cease

NOW, THEREFORE, in consideration of the mutual agreements and covenants set forth herein, Entegris and Eagle Delaware hereby agree as follows:

Table of Contents

(3) At the Effective Time, the separate existence of Entegris shall cease and the Reincorporation Merger shall have the other effects set forth in the provisions of the Delaware General Corporation Law and the Minnesota Business Corporation Act.

 

(4) At the Effective Time, by virtue of the Reincorporation Merger and without any action on the part of the holders thereof, each share of common stock of Entegris, par value $.01 per share (“Entegris Common Stock”), the only authorized class of capital stock of Entegris, shall be automatically converted into one share of common stock, par value $.01 per share, of the Reincorporation Merger Surviving Corporation (“Surviving Corporation Common Stock”).

 

(5) At the Effective Time, by virtue of the Reincorporation Merger and without any action on the part of the holder thereof, each share of common stock of Eagle Delaware, par value $.01 per share (“Eagle Delaware Common Stock”), outstanding and owned by Entegris, constituting the only Eagle Delaware capital stock outstanding immediately prior to the Effective Time, or held by Eagle Delaware as treasury shares, shall be cancelled and shall cease to exist, and no stock, cash or other property shall be issued in respect thereof.

 

1.2 Effective Time. Following (i) the requisite approval of this Plan of Merger and the Reincorporation Merger by the shareholders of Entegris and the stockholder of Eagle Delaware, (ii) the execution and filing with the Secretary of State of Delaware of a Certificate of Merger pursuant to Section 252 of the Delaware General Corporation Law and (iii) the execution and filing with the Secretary of State of Minnesota of Articles of Merger pursuant to Section 302A.615 of the Minnesota Business Corporation Act, the Reincorporation Merger shall become effective in Delaware upon the filing of such Certificate of Merger with the Secretary of State of Delaware and in Minnesota upon the filing of such Articles of Merger with the Secretary of State of Minnesota (the “Effective Time”).

 

1.3 No Appraisal or Dissenters Rights. In accordance with the provisions of Section 262 of the Delaware General Corporation Law and Section 302A.471 of the Minnesota Business Corporation Act, no holder of shares of Entegris Common Stock or Eagle Delaware Common Stock shall have any appraisal or dissenters rights as a result of the execution and delivery of this Plan of Merger or the consummation of the Reincorporation Merger.

 

ARTICLE II

EXCHANGE OF SHARES

 

2.1 Entegris Stock Certificates. At or after the Effective Time, each holder of shares of Entegris Common Stock immediately prior to the Effective Time, upon surrender to the Reincorporation Merger Surviving Corporation of the certificates which, prior to the Effective Time, evidenced outstanding shares of Entegris Common Stock, shall be entitled to receive in exchange therefor a certificate or certificates representing the number of shares of Surviving Corporation Common Stock into which such shares of Entegris Common Stock shall have been converted as provided in Section 1.1(4). Nothing stated herein shall require a holder of a certificate which represented a share of Entegris Common Stock immediately prior to the Effective Time to surrender such certificate. After the Effective Time, and until so surrendered, each such outstanding certificate for such shares of Entegris Common Stock that have been converted into shares of Surviving Corporation Common Stock in accordance with this Plan of Merger will be deemed for all corporate purposes of the Reincorporation Merger Surviving Corporation to evidence ownership of, and represent, the number of shares of Surviving Corporation Common Stock into which such shares of Entegris Common Stock were converted at the Effective Time. The registered owner on the books and records of the transfer agent of Eagle Delaware of any such outstanding certificate for shares of Entegris Common Stock shall, until such certificate shall have been surrendered for transfer, have and be entitled to all rights of a holder of Surviving Corporation Common Stock with respect to each share represented by such certificate, including all voting rights and rights to dividends and other distributions upon the shares of the Reincorporation Merger Surviving Corporation represented by such outstanding certificate.

2.2 Eagle Delaware Stock Certificates. At or after the Effective Time, Entegris shall surrender the certificates which, prior to the Effective Time, evidenced the outstanding shares of Eagle Delaware Common Stock to the Reincorporation Merger Surviving Corporation for cancellation and no stock, cash or other property shall be issued in respect thereof. After the Effective Time, and until so surrendered, no outstanding certificate for such shares of Eagle Delaware Common Stock outstanding prior to the Reincorporation Merger shall be deemed for any corporate purpose to represent any interest in Eagle Delaware or the Reincorporation Merger Surviving Corporation or to entitle the holder thereof to any stock, cash or other property.

If such business relates to any other matter, the stockholder must have given timely notice thereof in writing to the Secretary. To be timely, a stockholder’s notice must be delivered to or mailed and received at the principal executive offices of the Corporation not less than sixty (60) days nor more than ninety (90) days prior to the anniversary date of the immediately preceding annual meeting of stockholders; provided, however, that if the annual meeting is not held within thirty (30) days before or after such anniversary date, then for the notice by the stockholder to be timely it must be so received not later than the close of business on the 10th day following the date on which the notice of the meeting was mailed or such public disclosure was made, whichever occurs first. A stockholder’s notice to the Secretary shall set forth as to each matter the stockholder proposes to bring before the annual meeting (a) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting, (b) the name and address, as they appear on the Corporation’s books, of the stockholder proposing such business, (c) the class and number of shares of the Corporation which are beneficially owned by the stockholder and (d) any material interest of the stockholder in such business. Notwithstanding anything in these By-Laws to the contrary, no business shall be conducted at any annual meeting except in accordance with the procedures set forth in this Section 2.13, except that any stockholder proposal which complies with Rule 14a-8 or any successor provision or Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended, and is to be included in the Corporation’s proxy statement for an annual meeting of stockholders shall be deemed to comply with the requirements of this Section 2.13.

 

The chairman of the meeting shall, if the facts warrant, determine and declare to the meeting that business was not properly brought before the meeting in accordance with the provisions of this Section 2.13, and if he or she should so determine, the chairman shall so declare to the meeting and any such business not properly brought before the meeting shall not be transacted.

ARTICLE 7—INDEMNIFICATION

 

7.1 Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he or she is or was a director or an officer of the Corporation or is or was serving at the request of the Corporation as a director, officer or trustee of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (hereinafter an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a director, officer or trustee or in any other capacity while serving as a director, officer or trustee, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the Delaware General Corporation Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than such law permitted the Corporation to provide prior to such amendment), against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith; provided, however, that, except as provided in Section 7.3 of this Article 7 with respect to proceedings to enforce rights to indemnification, the Corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Board of Directors of the Corporation.

 

7.2 Right to Advancement of Expenses. In addition to the right to indemnification conferred in Section 7.1 of this Article 7, an indemnitee shall also have the right to be paid by the Corporation the expenses (including attorney’s fees) incurred in defending any such proceeding in advance of its final disposition (hereinafter an “advancement of expenses”); provided, however, that, if the Delaware General Corporation Law requires, an advancement of expenses incurred by an indemnitee in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such indemnitee, including, without limitation, service to an employee benefit plan) shall be made only upon delivery to the Corporation of an undertaking (hereinafter an “undertaking”), by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (hereinafter a “final adjudication”) that such indemnitee is not entitled to be indemnified for such expenses under Section 7.1 or otherwise.

 

7.3 Right of Indemnitee to Bring Suit. If a claim under Section 7.1 or 7.2 of this Article 7 is not paid in full by the Corporation within sixty (60) days after a written claim has been received by the Corporation, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be twenty (20) days, the indemnitee may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the indemnitee shall be entitled to be paid also the expense of prosecuting or defending such suit. In (i) any suit brought by the indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the indemnitee to enforce a right to an advancement of expenses) it shall be a defense that, and (ii) in any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that, the indemnitee has not met any applicable standard for indemnification set forth in the Delaware General Corporation Law. Neither the failure of the Corporation (including its directors who are not parties to such action, a committee of such directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such suit that indemnification of the indemnitee is proper in the circumstances because the indemnitee has met the applicable standard of conduct set forth in the Delaware General Corporation Law, nor an actual determination by the Corporation (including its directors who are not

 

D-11


Table of Contents

parties to such action, a committee of such directors, independent legal counsel, or its stockholders) that the indemnitee has not met such applicable standard of conduct, shall create a presumption that the indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the indemnitee, be a defense to such suit. In any suit brought by the indemnitee to enforce a right to indemnification or to an advancement of expenses hereunder, or brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the indemnitee is not entitled to be indemnified, or to such advancement of expenses, under this Article 7 or otherwise shall be on the Corporation.

 

7.4 Non-Exclusivity of Rights. The rights to indemnification and to the advancement of expenses conferred in this Article 7 shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, the Corporation’s Certificate of Incorporation, By-laws, agreement, vote of stockholders or directors or otherwise.

 

7.5 Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the Delaware General Corporation Law.

Gentlemen:

 

You have requested our opinion as to the fairness from a financial point of view to Entegris, Inc. (the “Company”) of the exchange ratio (the “Exchange Ratio”) of 1.39 shares of common stock, par value $0.01 per share (the “Eagle Delaware Common Stock”), of Eagle DE, Inc., a wholly owned subsidiary of the Company (“Eagle Delaware”), to be issued in exchange for each share of common stock, par value $0.01 per share (the “Mykrolis Common Stock”), of Mykrolis Corporation (“Mykrolis”) pursuant to the Agreement and Plan of Merger, dated as of March 21, 2005 (the “Agreement”), by and among the Company, Eagle Delaware and Mykrolis. Pursuant to the Agreement, (a) the Company will merge with and into Eagle Delaware and each share of common stock, par value $0.01 per share (the “Company Common Stock”), of the Company will be converted into 1 share of Eagle Delaware Common Stock and (b) immediately thereafter, Mykrolis will merge with and into Eagle Delaware and each share of Mykrolis Common Stock will be converted into a number of shares of Eagle Delaware Common Stock equal to the Exchange Ratio.

 

Goldman, Sachs & Co. and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. We have acted as financial advisor to the Company in connection with, and have participated in certain of the negotiations leading to, the transaction contemplated by the Agreement (the “Transaction”). We expect to receive fees for our services in connection with the Transaction, all of which are contingent upon consummation of the Transaction, and the Company has agreed to reimburse our expenses and indemnify us against certain liabilities arising out of our engagement. We have provided investment banking services to the Company from time to time and may provide investment banking services to the Company and Mykrolis in the future. In connection with the above-described services, we may receive compensation.

 

Goldman, Sachs & Co. is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman, Sachs & Co. and its affiliates may provide such services to the Company, Mykrolis and their affiliates, may actively trade the debt and equity securities (or related derivative securities) of the Company and Mykrolis for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.

 

In connection with this opinion, we have reviewed, among other things, the Agreement and the Reincorporation Plan of Merger (as defined in the Agreement); annual reports to stockholders and Annual Reports on Form 10-K of the Company for the five fiscal years ended August 28, 2004, and Mykrolis for the four fiscal years ended December 31, 2004; certain interim reports to stockholders and Quarterly Reports on Form 10-Q of the Company and Mykrolis; certain other communications from the Company and Mykrolis to their respective stockholders; certain internal financial analyses and forecasts for Mykrolis prepared by its

management; and certain financial analyses and forecasts for the Company and for Mykrolis prepared by the management of the Company (the “Forecasts”), including certain cost savings and operating synergies projected by the managements of the Company and Mykrolis to result from the Transaction (the “Synergies”). We also have held discussions with members of the senior managements of the Company and Mykrolis regarding their assessment of the strategic rationale for, and the potential benefits of, the Transaction and the past and current business operations, financial condition and future prospects of the Company and Mykrolis. In addition, we have reviewed the reported price and trading activity for the shares of Company Common Stock and the shares of Mykrolis Common Stock, compared certain financial and stock market information for the Company and Mykrolis with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the semiconductor industry specifically and in other industries generally and performed such other studies and analyses, and considered such other factors, as we considered appropriate.

 

We have relied upon the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by us and have assumed such accuracy and completeness for purposes of rendering this opinion. In that regard, we have assumed with your consent that the Forecasts, including the Synergies, have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the Company. In addition, we have not made an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of the Company or Mykrolis or any of their respective subsidiaries and we have not been furnished with any such evaluation or appraisal. We also have assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company or Mykrolis or on the expected benefits of the Transaction in any way meaningful to our analysis.

 

Our opinion does not address the underlying business decision of the Company to engage in the Transaction, nor are we expressing any opinion as to the prices at which shares of the Company Common Stock or shares of Eagle Delaware Common Stock will trade at any time. Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of the Company in connection with its consideration of the Transaction and such opinion does not constitute a recommendation as to how any holder of Company Common Stock should vote with respect to such Transaction.

 

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio pursuant to the Agreement is fair from a financial point of view to the Company.

 

Very truly yours,

/S/    GOLDMAN, SACHS & CO.

Mykrolis Corporation

Billerica, MA 01801

 

Members of the Board:

 

You have requested our opinion as to the fairness, from a financial point of view, to the holders of the common stock of Mykrolis Corporation (the “Company”) of the Exchange Ratio (defined below) set forth in an Agreement and Plan of Merger (the “Merger Agreement”) to be entered into among the Company, Entegris, Inc. (“Entegris”) and Eagle DE, Inc. (“New Entegris”). As more fully described in the Merger Agreement, (i) Entegris will be merged with and into New Entegris (the “Reincorporation Merger”), (ii) in the Reincorporation Merger, each outstanding share of the common stock, par value $0.01 per share of Entegris (“Entegris Common Stock”) (other than those shares specified in the Merger Agreement) will be converted into the right to receive one share of the common stock, par value $0.01 per share, of New Entegris (“New Entegris Common Stock”), (iii) following the Reincorporation Merger, the Company will be merged with and into New Entegris (the “Merger”), and (iv) in the Merger, each outstanding share of the common stock, par value $0.01 per share, of the Company (“Company Common Stock”) (other than those shares specified in the Merger Agreement) will be converted into the right to receive 1.39 shares (the “Exchange Ratio”) of New Entegris Common Stock.

 

In arriving at our opinion, we reviewed a draft dated March 19, 2005 of the Merger Agreement and held discussions with certain senior officers, directors and other representatives and advisors of the Company and certain senior officers and other representatives and advisors of Entegris concerning the businesses, operations and prospects of the Company, Entegris and New Entegris. We examined certain publicly available business and financial information relating to the Company and Entegris as well as certain financial forecasts and other information and data relating to the Company, Entegris and New Entegris which were provided to or discussed with us by the respective managements of the Company and Entegris. We reviewed the financial terms of the Merger as set forth in the Merger Agreement in relation to, among other things: current and historical market prices and trading volumes of Company Common Stock and Entegris Common Stock; the historical and projected earnings and other operating data of the Company, Entegris and New Entegris; and the capitalization and financial condition of the Company and Entegris. We analyzed certain financial, stock market and other publicly available information relating to the businesses of other companies whose operations we considered relevant in evaluating those of the Company and Entegris. We also evaluated certain potential pro forma financial effects of the Merger on New Entegris. In addition to the foregoing, we conducted such other analyses and examinations and considered such other information and financial, economic and market criteria as we deemed appropriate in arriving at our opinion.

 

In rendering our opinion, we have assumed and relied upon, without assuming any responsibility for independent verification of, the accuracy and completeness of all financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with us and upon the assurances of the managements of the Company and Entegris that they are not aware of any relevant information that has been omitted or that remains undisclosed to us. With respect to financial forecasts and other information and data relating to the Company, Entegris and New Entegris provided to or otherwise reviewed by or discussed with us, we have been advised by the respective managements of the Company and Entegris that such forecasts and other information and data were reasonably prepared on bases reflecting the best currently available estimates and judgments of the managements of the Company and Entegris as to the future financial performance of the Company, Entegris and New Entegris, and the other matters covered thereby, and have assumed, with your consent, that the financial results reflected in such forecasts and other information and data will be realized in the amounts and at the times projected. We have assumed, with your consent, that each of the Reincorporation

Merger and the Merger will be consummated in accordance with its terms, without waiver, modification or amendment of any material term, condition or agreement and that, in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the Reincorporation Merger and the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on the Company, Entegris, New Entegris or the contemplated benefits of the Reincorporation Merger or the Merger. Representatives of the Company have advised us, and we further have assumed, that the final terms of the Merger Agreement will not vary materially from those set forth in the draft reviewed by us. We also have assumed, with your consent, that the Merger will be treated as a tax-free reorganization for federal income tax purposes. Our opinion, as set forth herein, relates to the relative values of the Company and Entegris. We are not expressing any opinion as to what the value of the New Entegris Common Stock actually will be when issued pursuant to the Merger or the price at which the New Entegris Common Stock will trade at any time. We have not made or been provided with an independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of the Company or Entegris nor have we made any physical inspection of the properties or assets of the Company or Entegris. Our opinion does not address the relative merits of the Merger as compared to any alternative business strategies that might exist for the Company or the effect of any other transaction in which the Company might engage. Nor were we requested to consider, and our opinion does not address, the relative merits of the Merger as compared to any alternative business strategies that might exist for the Company or the effect of any other transaction in which the Company might engage. Our opinion is necessarily based upon information available to us, and financial, stock market and other conditions and circumstances existing, as of the date hereof.

 

Citigroup Global Markets Inc. has acted as financial advisor to the Company in connection with the proposed Merger and will receive a fee for such services, a significant portion of which is contingent on the consummation of the Merger. We and our affiliates in the past have provided services to the Company and Entegris unrelated to the proposed Merger, for which services we and such affiliates have received compensation, including, without limitation, acting as the lead manager in connection with the Company’s initial public offering and acting as co-manager in connection with Entegris’s initial public offering. In the ordinary course of our business, we and our affiliates may actively trade or hold the securities of the Company, Entegris and New Entegris for our own account or for the account of our customers and, accordingly, may at any time hold a long or short position in such securities. In addition, we and our affiliates (including Citigroup Inc. and its affiliates) may maintain relationships with the Company, Entegris, New Entegris and their respective affiliates.

 

Our advisory services and the opinion expressed herein are provided for the information of the Board of Directors of the Company in its evaluation of the proposed Merger, and our opinion is not intended to be and does not constitute a recommendation to any stockholder as to how such stockholder should vote or act on any matters relating to the proposed Merger.

 

Based upon and subject to the foregoing, our experience as investment bankers, our work as described above and other factors we deemed relevant, we are of the opinion that, as of the date hereof, the Exchange Ratio is fair, from a financial point of view, to the holders of Company Common Stock.

 

Very truly yours,

PART II

 

Item 20. Indemnification of Directors and Officers

 

Entegris, Inc. is subject to Minnesota Statutes Chapter 302A, the Minnesota Business Corporation Act. Section 302A.521 of the Minnesota Business Corporation Act provides in substance that, unless prohibited by its articles of incorporation or bylaws, a corporation must indemnify an officer or director who is made or threatened to be made a party to a proceeding by reason of his official capacity against judgments, penalties, fines, settlements and reasonable expenses, including attorneys’ fees and disbursements, incurred by such person in connection with the proceeding, if certain criteria are met. These criteria, all of which must be met with respect to the person to be indemnified, are (a) that such person has not been indemnified by another organization for the same judgments, penalties, fines, settlements and expenses; (b) that such person must have acted in good faith; (c) that no improper personal benefit was obtained by such person and such person satisfied certain statutory conflicts of interest provisions, if applicable; (d) that in the case of a criminal proceeding, such person had no reasonable cause to believe that the conduct was unlawful; and (e) that such person must have acted in a manner the person reasonably believed was in the best interests of the corporation or, in certain limited circumstances, not opposed to the best interests of the corporation. The determination as to eligibility for indemnification is made by the members of the corporation’s board of directors or a committee of the board who are at the time not parties to the proceedings under consideration, by special legal counsel, by the stockholders who are not parties to the proceedings or by a court.

 

Article 6 of Entegris’ Amended and Restated Bylaws, as amended, requires indemnification by Entegris to the same extent permitted by the laws of the State of Minnesota.

 

Entegris also maintains a director and officer insurance policy to cover Entegris, its directors and its officers against certain liabilities.

 

Eagle DE, Inc. (“Entegris Delaware”) is incorporated under the laws of the State of Delaware. Section 145 (“Section 145”) of the General Corporation Law of the State of Delaware, as the same exists or may hereafter be amended (the “DGCL”), inter alia, provides that a Delaware corporation may indemnify any persons who were, are or are threatened to be made parties to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was an officer, director, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was illegal.

 

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against him and incurred by him in any such capacity, arising out of his status as such, whether or not the corporation would otherwise have the power to indemnify him under Section 145.

 

Entegris Delaware’s certificate of incorporation provides that the registrant’s directors shall not be liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent that the exculpation from liabilities is not permitted under the DGCL as in effect at the time such liability is determined. Entegris Delaware’s certificate of incorporation provides that the corporation shall indemnify its directors to the full extent permitted by the laws of the State of Delaware. In addition, Entegris Delaware’s bylaws provide for indemnification of the registrant’s officers and directors to the fullest extent permitted by applicable law.

 

II-1


Table of Contents

All of Entegris Delaware’s directors and officers will be covered by insurance policies maintained by Entegris Delaware against specified liabilities for actions taken in their capacities as such, including liabilities under the Securities Act of 1933. In addition, Entegris Delaware will enter into indemnification agreements with each of its directors and executive officers that provide for indemnification and expense advancement to the fullest extent permitted under the DGCL.

Information requested hereunder is furnished as Exhibits 99.3 and 99.4 to this registration statement.

 

Item 22. Undertakings.

 

  (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933 (sometimes referred to herein as the “Securities Act”), each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

 

  (g)(1) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

 

  (g)(2) The undersigned registrant hereby undertakes that every prospectus: (i) that is filed pursuant to paragraph 1 immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

 

  (h) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

 

The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the information statement-prospectus pursuant to Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

 

The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
