JOINT PROXY STATEMENT/PROSPECTUS

GRAPHIC   GRAPHIC

Dear Holders of Veeco and FEI Common Stock:

        We are writing to you today about the proposed merger of Veeco Instruments Inc. and FEI Company. We are very excited about the opportunities we envision for the combined company. This merger will create a combined company that is a leader in metrology and process equipment solutions for the semiconductor, data storage, telecommunications/wireless and scientific research markets.

        Upon completion of the merger, each outstanding share of FEI common stock will be exchanged for 1.355 shares of Veeco common stock. Veeco expects to issue approximately 44,000,000 shares of its common stock in the merger to FEI shareholders (and up to approximately 10,000,000 Veeco shares which may be issued in respect of FEI's options and other rights and convertible notes). Upon completion of the merger, former FEI shareholders will own approximately 60% of Veeco's outstanding common stock (not including the effect of shares issuable in respect of options, convertible debt and other convertible securities and rights). Veeco common stock is quoted on The Nasdaq National Market under the symbol "VECO". As of November 6, 2002, the closing price of Veeco's common stock on The Nasdaq National Market was $12.41 per share.

        Attached are notices of special meetings of holders of Veeco and FEI common stock and a joint proxy statement/prospectus relating to the merger. The accompanying joint proxy statement/prospectus is the proxy statement for FEI's special meeting of shareholders to vote on the merger and for Veeco's special meeting of stockholders to vote on the issuance of Veeco common stock in the merger, certain amendments to Veeco's Amended and Restated Certificate of Incorporation and an amendment to Veeco's First Amended and Restated Employee Stock Purchase Plan. It also is the prospectus of Veeco related to the issuance of Veeco common stock to the FEI shareholders in the merger.

        Completion of the merger requires the FEI shareholders to approve the merger and the Veeco stockholders to approve the issuance of Veeco common stock in the merger and approve the amendment to Veeco's Amended and Restated Certificate of Incorporation to increase the authorized shares of Veeco's common stock so that there will be sufficient authorized shares for issuance in the merger.

        The merger and an investment in Veeco common stock involve risks. You should carefully consider the discussion in the section titled "Risk Factors" beginning on page 14 of the joint proxy statement/prospectus.

        After careful consideration, the Veeco and FEI boards of directors unanimously recommend the merger. Your vote is important. Please vote "FOR" your company's proposal(s) by signing and dating the enclosed proxy card and returning it in the pre-addressed envelope provided. If you are an FEI shareholder and you do not return your proxy card or vote in person at the FEI meeting of shareholders, the effect will be the same as a vote against the merger. If you are a Veeco stockholder and you do not return your proxy card or vote in person at the Veeco meeting of stockholders in favor of the proposed amendments to Veeco's Amended and Restated Certificate of Incorporation, the effect will be the same as a vote against these proposed amendments.

        We appreciate your consideration of these matters.

QUESTIONS AND ANSWERS

Q:
What transactions are proposed?

A:
Venice Acquisition Corp., a wholly-owned subsidiary of Veeco Instruments Inc., will be merged with and into FEI Company and FEI will become a wholly-owned subsidiary of Veeco after the merger.
Q:
Why am I receiving this joint proxy statement/prospectus?

A:

Q:
What will FEI shareholders receive in the merger?

A:

The number of shares issuable and the exercise prices payable upon the exercise of these options, and the number of shares into which the FEI notes are convertible, will be adjusted using the exchange ratio for the merger of 1.355 shares of Veeco common stock for each share of FEI common stock. At June 30, 2002, a total of approximately 10,000,000 Veeco shares would have been issuable under FEI's options and other rights and convertible notes assuming the merger had occurred on that date.

Q:
What is the value of the merger consideration?

A:
No. Under Delaware and Oregon law, neither Veeco stockholders nor FEI shareholders will be entitled to dissent from the merger or request an appraisal of the value of their shares.

Q:
What vote is needed for the proposed amendment to Veeco's Amended and Restated Certificate of Incorporation to change the name of Veeco Instruments Inc. to Veeco FEI Inc.?

A:
No. After the merger is completed, FEI shareholders will receive a letter of transmittal and other documentation from the exchange agent in the merger, together with written instructions for exchanging their FEI stock certificates for Veeco FEI stock certificates.

Q:
When do you expect the merger to be completed?

A:
We are working toward completing the merger as quickly as possible and hope to complete the merger shortly after the FEI special meeting and the Veeco special meeting.

Q:
Who should I call with questions?

Veeco stockholders should call either Georgeson Shareholder Communications Inc. at (212) 805-7000 or Veeco Investor Relations at (516) 677-0200, ext. 1403 with any questions about the merger.

Interests of Certain Persons in the Merger

In considering the recommendation of the FEI board of directors that FEI shareholders vote to approve the merger and the recommendation of the Veeco board of directors that Veeco stockholders vote to approve the issuance of Veeco common stock in the merger, the proposed amendments to Veeco's Amended and Restated Certificate of Incorporation and the proposed amendment to Veeco's First Amended and Restated Employee Stock Purchase Plan, FEI shareholders and Veeco stockholders should note that certain directors and officers of Veeco and FEI have interests in the merger that are different from, or in addition to, their interests as stockholders/shareholders. These interests relate to the composition of the Veeco FEI board of directors and the management of Veeco FEI following the merger, employment agreements, potential severance payments, potential accelerated vesting of stock options, indemnification rights and certain rights granted to PBE, FEI's largest shareholder, under the investor agreement. For more information, see the section titled "The Merger—Interests of Executive Officers and Directors in the Merger" beginning on page 70.

10


the terms and conditions of the investor agreement, see the section titled "Other Agreements—Investor Agreement with PBE" beginning on page 97.


Material U.S. Federal Income Tax Consequences of the Merger

The receipt of shares of Veeco common stock in the merger generally will be tax-free to FEI shareholders for U.S. federal income tax purposes, except for tax on gain resulting from the receipt of cash in lieu of fractional shares.

Tax matters are very complicated, and the tax consequences of the merger to each FEI shareholder will depend on the facts of such shareholder's own situation. FEI shareholders are urged to consult their own tax advisors as to the specific tax consequences of the merger to them, including the applicable federal, state, local and foreign tax consequences.

For more information, see the section titled "The Merger—Material U.S. Federal Income Tax Consequences of the Merger" beginning on page 75.


No Appraisal/Dissenters' Rights

In connection with the merger, neither Veeco stockholders nor FEI shareholders are entitled to dissent from the merger or request an appraisal of the value of their shares under Delaware or Oregon law. For more information see the section titled "The Merger Agreement—Merger Consideration—No Appraisal/Dissenters' Rights" on page 78.


Accounting Treatment of the Merger

The merger will be accounted for using the purchase method for financial reporting and accounting purposes. After the merger, FEI's post-merger results of operations will be included in the consolidated financial statements of Veeco. For more information, see the section titled "The Merger—Accounting Treatment of the Merger" on page 76.


Restrictions on Selling Veeco Common Stock Received in the Merger

All shares of Veeco common stock received by FEI shareholders in connection with the merger will be freely transferable, unless the holder is an affiliate of FEI or Veeco. For a more complete description of transfer restrictions that apply to these affiliates, see the section titled "The Merger—Resale of Veeco Common Stock Issued in the Merger" beginning on page 74.


Ownership of Veeco FEI Following the Merger

Based upon the number of shares of FEI common stock outstanding on the FEI record date, Veeco expects to issue a total of approximately 44,000,000 shares of Veeco common stock to FEI shareholders in connection with the merger and may be required to issue additional shares of Veeco common stock in the future upon exercise of FEI stock options and other rights and conversion of the FEI notes. Based upon the number of shares of Veeco common stock outstanding on the Veeco record date, the former holders of FEI common stock will hold approximately 60% of the total number of issued and outstanding shares of Veeco common stock after completion of the merger (not including the effect of shares issuable in respect of options, convertible debt and other convertible securities and rights).

Based upon the number of outstanding options to purchase shares of FEI common stock as of June 30, 2002, those FEI options will become options to purchase an aggregate of approximately 4,174,461 shares of Veeco common stock following the merger.

Based on the number of shares of FEI common stock issuable upon conversion of the FEI notes as of June 30, 2002, the FEI notes will become convertible into an aggregate of approximately 4,788,470 shares of Veeco common stock following the merger.

        This joint proxy statement/prospectus and the documents incorporated by reference herein contain certain forward-looking statements about Veeco, FEI and the combined company within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve risks and uncertainties. Forward-looking statements include, without limitation, expectations about market conditions or about market acceptance, expectations of future sales or gross profits, possible or assumed future results of operations of Veeco and FEI and the integration of the merged companies and the statements included in the sections titled "The Merger—Veeco's Reasons for the Merger" and "The Merger—FEI's Reasons for the Merger". Forward-looking statements relate to expectations concerning matters that are not historical facts. Words or phrases such as "will likely result," "expect," "will continue," "anticipate," "believe," "estimate," "intend," "plan," "project" or similar expressions are intended to identify forward-looking statements. Actual results may vary materially from those expressed in such forward-looking statements as a result of various factors, including:

        Although each of Veeco and FEI believes that the forward-looking statements contained in this joint proxy statement/prospectus are reasonable, neither can assure you that the forward-looking statements will prove to be correct. Factors which could cause actual results to differ also include those set forth in the section titled "Risk Factors" beginning on page 14 and elsewhere throughout this joint proxy statement/prospectus and the documents incorporated by reference herein.

13


RISK FACTORS

        Veeco stockholders and FEI shareholders should consider the following factors, in addition to other risk factors of the two companies incorporated by reference into this joint proxy statement/prospectus and the other information contained in this document, in deciding whether to vote for approval of the merger, in the case of FEI shareholders, or for approval of the issuance of Veeco common stock in the merger, the amendments to Veeco's Amended and Restated Certificate of Incorporation and the amendment to Veeco's First Amended and Restated Employee Stock Purchase Plan, in the case of Veeco stockholders. See the section titled "Where You Can Find More Information" beginning on page 134 for where you can find additional risk factors incorporated by reference herein.

Risks Related to the Merger and Receipt of Veeco Stock

        Because FEI shareholders will receive a fixed ratio of 1.355 shares of Veeco common stock in exchange for each share of FEI common stock regardless of changes in the relative market values of each stock, the dollar value of the consideration received by FEI shareholders may be lower on the day of closing than it was on the day of the public announcement of the merger or the day this joint proxy statement/prospectus was filed.

        Upon completion of the merger, each share of FEI common stock will be converted into the right to receive 1.355 shares of Veeco common stock. The market values of Veeco common stock and FEI common stock have varied since Veeco and FEI entered into the merger agreement and may continue to vary in the future due to, among other factors:

        The dollar value of Veeco common stock that FEI shareholders will receive upon completion of the merger will depend on the market value of Veeco common stock at the closing of the merger, which may be different from, and lower than, the closing price of Veeco common stock on the last full trading day preceding the date of the public announcement of the merger agreement, the last full trading day prior to the date of this joint proxy statement/prospectus or the date(s) of the special meetings. The price of Veeco common stock has declined from a price per share of $22.49 on July 11, 2002, the last full trading day preceding the date of the public announcement of the merger agreement to a price per share of $12.41 on November 6, 2002, the last full trading day prior to the date of the filing of Amendment No. 2 to the Registration Statement of which this joint proxy statement/prospectus forms a part. Moreover, the closing of the merger may occur some time after stockholder approval has been obtained. There will be no adjustment to the exchange ratio (except for adjustments to reflect the

14

effect of any stock split or other recapitalization of Veeco common stock or FEI common stock), and the parties do not have a right to terminate the merger agreement based upon changes in the market price of either Veeco common stock or FEI common stock.

        The stock market in general and the market for shares of technology companies in particular have experienced extreme stock price fluctuations. In some cases, these fluctuations have been unrelated to the operating performance of the affected companies. Many companies in the data storage, semiconductor and related equipment industries, including Veeco, have experienced dramatic volatility in the market prices of their common stock. Veeco believes that a number of factors, both within and outside Veeco's control, could cause the price of Veeco common stock to fluctuate, perhaps substantially. These factors include:

        Veeco cannot be certain that the market price of Veeco common stock will not experience significant fluctuations in the future, including fluctuations that are material, adverse and unrelated to Veeco's performance.

        The combined company may not realize certain potential benefits from the merger because of integration and other challenges, which could negatively impact its results of operations.

        Veeco and FEI entered into the merger agreement with the expectation that the merger will result in benefits to the combined company. To realize benefits or synergies from the merger, the combined company will face the following post-merger challenges, among others:

15

        If the combined company is not successful in addressing these and other challenges, then some or all of the benefits of the merger will not be realized and, as a result, the combined company's operating results and the market price of the combined company's common stock may be adversely affected. Further, neither Veeco nor FEI can assure you that the growth rate of the combined company will equal the historical growth rates experienced by either Veeco or FEI.

        Since commencing operations in 1990, Veeco has made 11 acquisitions. In connection with the integration of these acquisitions, Veeco has faced a number of challenges, including difficulties in incorporating acquired technology and rights into Veeco's products, maintaining uniform standards, controls, procedures and policies, and integrating each acquired company's information technology systems. Many of these acquisitions have diverted management's attention from other business concerns and have exposed Veeco to unforeseen liabilities or risks associated with entering new markets and acquiring new and unproven technologies. Integration of these prior acquisitions has been costly and time consuming. In addition, Veeco has paid for some of these acquisitions by issuing additional shares of its common stock, which in certain instances was dilutive to its then-existing stockholders.

        Since 1996, FEI has completed two significant business combinations and made several smaller acquisitions. In connection with the integration of these acquired businesses, FEI has faced a number of challenges, many of which are similar to those that Veeco faced in connection with its acquisitions. In addition, FEI has paid for some of these acquisitions in part by issuing additional shares of its common stock, which in certain instances was dilutive to its then-existing shareholders.

        The market price of the combined company's common stock may decline as a result of the merger.

        The market price of the combined company's common stock may decline as a result of the merger for a number of reasons, including if:

        Veeco's and FEI's officers and directors have interests different from yours that may have influenced them to support or approve the merger.

        The directors and officers of Veeco and FEI have entered or may enter into arrangements that may create interests in the merger that are different from, or in addition to, yours, including the following:

16

        For the above reasons, the directors and officers of Veeco and FEI may have been more likely to support and recommend the approval of the merger agreement than if they did not hold these interests. Veeco stockholders and FEI shareholders should consider whether these interests may have influenced these directors and officers to support or recommend the merger. You should read more about these interests in the section titled "The Merger—Interests of Executive Officers and Directors in the Merger" beginning on page 70.

        In addition, two directors of FEI are also employees or officers of Philips and/or PBE. In connection with the merger, Philips and PBE entered into certain agreements with FEI and Veeco. For a description of these agreements, see the sections titled "Other Agreements—Voting Agreement with FEI Shareholders," "Other Agreements—Investor Agreement with PBE", "Other Agreements—Amendment Agreement among FEI, PBE and Philips" and "Relationship with Philips" and the documents filed by FEI with the SEC which are incorporated by reference in this joint proxy statement/prospectus. See the section titled "Where You Can Find More Information" beginning on page 134.

        Failure to complete the merger could harm Veeco's and FEI's future businesses, operations and stock prices.

        Veeco and FEI face a number of special risks if the merger is not completed, including the following risks:

        Uncertainty regarding the merger and the effects of the merger could cause customers or strategic partners to delay or defer decisions, which could negatively affect the combined company's revenues.

        Veeco's and/or FEI's customers and strategic partners, in response to the announcement of the merger, may delay or defer decisions, which could have a material adverse effect on the business of the

relevant company, regardless of whether the merger is ultimately completed. In particular, prospective customers could be reluctant to purchase the combined company's products due to uncertainty about the direction of the combined company's product offerings and willingness to support and service existing products. To the extent that the merger creates uncertainty among those persons and organizations such that one large customer or a significant group of smaller customers, delays, defers or changes purchases in connection with the planned merger, revenue of the combined company would be adversely affected.

        In order to be successful, the combined company must retain and motivate key employees, which will be more difficult in light of uncertainty regarding the merger, and failure to do so could seriously damage the combined company.

        In order to be successful, the combined company must retain and motivate executives and other key employees, including those in managerial, technical, marketing and information technology support positions. In particular, the combined company's product generation efforts depend on hiring and retaining qualified engineers. In addition, experienced management and technical, marketing and support personnel in the information technology industry are in high demand and competition for their talents is intense. Employee retention may be a particularly challenging issue in connection with the merger as employees of Veeco and FEI may experience uncertainty about their future role with the combined company until or after strategies with regard to the combined company are announced or executed. This circumstance may adversely affect the combined company's ability to attract and retain key management, sales, marketing and technical personnel.

        Regulators may take action that could affect, delay or prohibit the merger or negatively affect the combined company and stockholders may not be able to change their vote in the event of any such action.

        Veeco and FEI cannot complete the merger until they give notification and furnish information to the Federal Trade Commission and the Antitrust Division of the Department of Justice and observe a statutory waiting period under the HSR Act. Also, prior to completion of the merger, Veeco and FEI need to make filings with certain foreign competition authorities and comply with applicable foreign merger control laws. Veeco and FEI filed the required notification and report forms with the Federal Trade Commission and the Antitrust Division and have made or intend to make filings with certain foreign antitrust authorities. On September 18, 2002, Veeco and FEI received a request from the Antitrust Division of the Department of Justice for additional information under the HSR Act regarding the merger. This second request has the effect of extending the waiting period under the HSR Act until 30 days after Veeco and FEI comply with the request. Veeco and FEI intend to fully cooperate and promptly respond to this request. The companies currently cannot estimate how long it will take to comply with this request. There can be no assurances that regulators will terminate the waiting period under the HSR Act or allow the waiting period to expire or will not take action to prohibit the merger or condition the merger on restrictions that would negatively impact the combined company. At any time before or after the closing of the merger, the Federal Trade Commission, the Antitrust Division of the Department of Justice or any state or foreign competition authority could take any action under applicable antitrust or competition laws as it deems necessary or desirable, including challenging the merger. Private parties and state attorneys general may also challenge the transaction and seek to enjoin the merger under U.S. or foreign antitrust laws under certain circumstances.

        Charges to earnings resulting from the application of the purchase method of accounting may adversely affect the market price of Veeco FEI's common stock following the merger.

        In accordance with United States generally accepted accounting principles, the combined company will account for the merger using the purchase method of accounting, which will result in charges to earnings that could have a material adverse effect on the market price of the Veeco FEI common stock following completion of the merger. Under the purchase method of accounting, the combined company will allocate the total estimated purchase price to FEI's net tangible assets, amortizable intangible assets, intangible assets with indefinite lives and in-process research and development based on their

18

fair values as of the date of completion of the merger, and record the excess of the purchase price over those fair values as goodwill. The portion of the estimated purchase price allocated to in-process research and development will be expensed by the combined company in the quarter in which the merger is completed. The combined company will incur additional depreciation and amortization expense over the useful lives of certain of the net tangible and intangible assets acquired in connection with the merger. Purchase accounting also requires fair valuation of assets that will result in the capitalization of profit in inventory and the loss of certain revenue and related deferred gross profit recorded in accordance with Staff Accounting Bulletin No. 101. In addition, to the extent the value of goodwill or intangible assets with indefinite lives become impaired, the combined company may be required to incur material charges relating to the impairment of those assets. These depreciation, amortization, in-process research and development and potential impairment charges could have a material impact on the combined company's results of operations.

Risks Related to the Combined Company

        The following describes risks related to Veeco FEI—the combined company following the merger. Veeco stockholders and FEI shareholders will be stockholders of Veeco FEI following the merger.

        The combined company will depend on the data storage, telecommunications/wireless, semiconductor and scientific research industries. Cyclicality in these markets may affect the combined company's business.

        The combined company's business will depend in large part upon the capital expenditures of data storage, telecommunications/wireless, semiconductor and scientific research customers, which accounted for the following percentages of combined net sales of Veeco and FEI for the periods indicated:

Scientific Research and Industrial   19 % 38 % 28 % 22 % 46 % 33 % 35 % 50 % 43 %

        The data storage, telecommunications/wireless, semiconductor and scientific research industries are cyclical. These industries have experienced significant economic downturns at various times in the last decade, characterized by diminished product demand, accelerated erosion of average selling prices and production overcapacity. A downturn in one or more of these industries, or the businesses of one or more of the combined company's customers, could have a material adverse effect on the combined company's business, prospects, financial condition and operating results.

        The current global downturn in general economic conditions and in the markets for Veeco's and FEI's customers' products is resulting in a reduction in demand for some of Veeco's and FEI's products. Veeco and FEI have experienced the effects of the global economic downturn in many areas of their businesses. During this downturn and any subsequent downturns the combined company cannot assure you that its sales or margins will not decline. As a capital equipment provider, the combined company's revenues will depend in large part on the spending patterns of customers, who often delay expenditures or cancel orders in reaction to variations in their businesses or general economic conditions. Because a high proportion of the combined company's costs will be fixed, the combined company will have a limited ability to reduce expenses quickly in response to revenue shortfalls. In a prolonged economic downturn, the combined company may not be able to reduce its significant fixed costs, such as continued investment in research and development or capital equipment requirements. In addition, during an economic downturn, the combined company may experience delays in collecting receivables, which may impose constraints on its working capital.

19

        Variations in the amount of time it takes for the combined company to sell its systems may cause fluctuations in the combined company's operating results which could negatively impact its stock price.

        Historically, both Veeco and FEI have experienced long and unpredictable sales cycles. Variations in the length of the combined company's sales cycles could cause the combined company's net sales, and therefore its business, financial condition, operating results and cash flows, to fluctuate widely from period to period. These variations will be based upon factors partially or completely outside the combined company's control. The factors that could affect the length of time it takes the combined company to complete a sale will depend upon many elements, including:

As a result of these and a number of other factors that could influence sales cycles with particular customers, the period between initial contact with a potential customer and the time when the combined company recognizes revenue from that customer, if ever, may vary widely. The combined company's sales cycle could typically take up to twelve months. Sometimes the combined company's sales cycle will be much longer. For instance, during an economic downturn or when a sale involves developing new applications for a system or technology, the sales cycle could be significantly extended. To complete sales during an economic downturn or sales involving new applications or technologies, for example, the combined company could commit substantial resources to its sales efforts before receiving any revenue, and may never receive any revenue from a customer despite these sales efforts which could have a negative impact on the combined company's revenues.

        In addition to lengthy and sometimes unpredictable sales cycles, the build cycle, or the time it will take the combined company to build a product to customer specifications, will typically range from one to six months. During this period, the customer may cancel its order, although generally it will be required to pay the combined company a fee based on the stage of the build cycle the combined company has completed.

        For many of the combined company's products, after a customer has purchased one of the combined company's systems, the combined company will provide an acceptance period during which the customer may evaluate the performance of the system and potentially reject the system. In addition, customers will often evaluate the performance of the combined company's systems for a lengthy period before purchasing any additional systems. The number of additional products a customer may purchase, if any, will often depend on many factors that are difficult to predict accurately, including a customer's capacity requirements and changing market conditions for its products. As a result of these evaluation periods and other factors, the period between a customer's initial purchase and subsequent purchases, if any, will often vary widely, and variations in length of this period could cause further fluctuations in the combined company's operating results.

        The combined company's business and financial results for a particular period could be materially and adversely affected if orders are canceled or rescheduled or if an anticipated order for even one system is not received in time to permit shipping during the period.

        Customers will continue to be able to cancel or reschedule orders, generally with limited or no penalties. In addition, Veeco has, in limited circumstances, permitted major customers to return previously shipped products in order to maintain business relationships with such customers. The

20

amount of purchase orders at any particular date, therefore, is not necessarily indicative of sales to be made in any succeeding period. In addition, the combined company will derive a substantial portion of its net sales in any fiscal period from the sale of a relatively small number of high-priced systems. As a result, the timing of revenue recognition for a single transaction could have a material effect on the combined company's sales and operating results for a particular fiscal period. Backlog adjustments for Veeco for the year ended December 31, 2001 included order cancellations of $136.3 million, of which approximately $110 million related to orders from the optical telecommunications industry. FEI did not have significant order cancellations for the year ended December 31, 2001.

        Because the combined company will not have long-term contracts with its customers, its customers may stop purchasing its products at any time which would adversely affect its results of operations.

        Historically, neither Veeco nor FEI have had long-term contracts with their customers. Consequently, it is not currently anticipated that the combined company will have long-term contracts with its customers. Accordingly:

        If the combined company does not succeed in obtaining new sales orders from new or existing customers, it will have a negative impact on its results of operations.

        The combined company will rely on a limited number of parts, components and equipment manufacturers. Failure of any of these suppliers to perform in a timely or quality manner could negatively impact revenues.

        Failure of critical suppliers of parts, components and manufacturing equipment to deliver sufficient quantities to the combined company in a timely and cost-effective manner could negatively affect the combined company's business. Both Veeco and FEI currently use numerous vendors to supply parts, components and subassemblies for the manufacture and support of their respective products. However, some key parts may be obtained only from a single supplier or a limited group of suppliers. In particular, FEI relies on Philips' Enabling Technology Group, a wholly-owned subsidiary of Philips, and Frencken Group B.V. for its supply of mechanical parts and subassemblies and RIPA Holding B.V. as a sole source for some of its electronic subassemblies. As a result of this concentration of key suppliers, the combined company's results of operations may be materially and adversely affected if, in the future, it does not timely and cost-effectively receive a sufficient quantity of parts to meet its production requirements or if it is required to find alternative suppliers for these supplies. The combined company will not be immediately seeking to expand its supplier group or to reduce its dependence on single suppliers. From time to time, FEI has experienced supply constraints with respect to the mechanical parts and subassemblies produced by Philips Enabling Technologies Group. If Philips Enabling Technologies Group is not able to supply the combined company's requirements, these constraints may affect the combined company's ability to deliver products to customers in a timely manner, which could have an adverse effect on the combined company's results of operations. Moreover, as a result of the reduction of PBE's ownership of FEI common stock after FEI's most recent public offering of common stock in May 2001, the cost of the parts and subassemblies purchased by the combined company from Philips Enabling Technologies Group and Philips may increase.

        The combined company will also rely on a limited number of equipment manufacturers to develop and supply the equipment it uses to manufacture its products. The failure of these manufacturers to develop or deliver equipment on a timely basis could have a material adverse effect on the combined company's business and results of operations. In addition, as a result of the small number of equipment suppliers, the combined company may be more exposed to future cost increases for this equipment.

21

        Because Veeco and FEI have significant operations in countries outside of the United States, the combined company may be subject to political, economic and other conditions affecting such countries that could result in increased operating expenses and regulation of its products.

        Because significant portions of Veeco's and FEI's operations occur outside the United States, the combined company's revenues will be impacted by foreign economic and regulatory environments. For example, the combined company will have manufacturing facilities in Brno, Czech Republic and Eindhoven, Netherlands and sales offices in several other countries. In addition, approximately 35% of Veeco's sales and approximately 29% of FEI's sales in 2000 and approximately 28% of Veeco's sales and approximately 25% of FEI's sales in 2001 were derived from sales in Asia. In recent years, Asian economies have been highly volatile and recessionary, resulting in significant fluctuations in local currencies and other instabilities. Instabilities in Asian economies may continue and recur in the future, which could have a material adverse effect on the combined company's business, prospects, financial condition and operating results. The combined company's exposure to the business risks presented by Asian economies and other foreign economies will increase to the extent it continues to expand its global operations. International operations will continue to subject the combined company to a number of risks, including:

        The combined company will be exposed to foreign currency exchange rate and interest rate risks that could adversely affect its revenues and gross margins.

        The combined company will be exposed to foreign currency exchange rate risks that will be inherent in its sales commitments, anticipated sales, and assets and liabilities that are denominated in currencies other than the United States dollar. The combined company also will be exposed to interest rate risks inherent in its debt and investment portfolios. Failure to sufficiently hedge or otherwise manage foreign currency risks properly could adversely affect the combined company's revenues and gross margins. A decrease in interest rates could adversely affect the combined company's interest income and results of operations.

        Neither Veeco nor FEI enters into derivative financial instruments for speculative or trading purposes. From time to time FEI enters into forward sale or purchase contracts for foreign currencies to hedge specific receivables or payables positions. Veeco enters into monthly forward contracts to reduce the effect of fluctuating foreign currencies on short-term foreign currency-denominated intercompany balances and other known currency exposures. The average notional amount of such contracts for Veeco was approximately $1.6 million for the six months ended June 30, 2002. As of June 30, 2002, Veeco did not have any open forward contracts. Veeco estimates that, based upon its June 30, 2002 balance sheet, a 10% change in foreign currency exchange rates would be immaterial to reported operating profit. As of June 30, 2002, the aggregate stated amount of these contracts for FEI was $35.5 million. FEI estimates that, based upon its June 30, 2002 balance sheet, a 10% change in foreign currency exchange rates would decrease the market value of its foreign currency contracts outstanding as of June 30, 2002 by approximately $3.1 million. FEI believes that this decrease in value would substantially be offset by the revaluation of the underlying hedged transactions.

22

        The loss of one or more of Veeco's or FEI's key customers would result in the loss of a significant amount of the combined company's net revenues.

        A relatively small number of customers account for a large percentage of Veeco's and FEI's net revenues. This situation is expected to continue for the combined company. The combined company's business will be seriously harmed if it does not generate as much revenue as it expects from these customers, experiences a loss of any of its significant customers or suffers a substantial reduction in orders from these customers. The combined company's ability to continue generating revenues from its key customers will depend on its ability to introduce new products acceptable to these customers. In 2001, Veeco's and FEI's two largest customers accounted for 16% and 13% of their respective net revenues.

        The combined company's customers may be adversely affected by rapid technological change and it may be unable to introduce new products on a timely basis.

        The data storage, telecommunications/wireless, semiconductor and scientific research industries are subject to rapid technological change and new product introductions and enhancements. The combined company's ability to remain competitive will depend in part upon its ability to develop, in a timely and cost-effective manner, new and enhanced systems at competitive prices and to accurately predict technology transitions. In addition, new product introductions or enhancements by competitors could cause a decline in sales or loss of market acceptance of the combined company's existing products. Increased competitive pressure also could lead to intensified price competition resulting in lower margins, which could materially and adversely affect the combined company's business, prospects, financial condition and operating results. The combined company's success in developing, introducing and selling new and enhanced systems depends upon a variety of factors, including:

        Because new product development commitments must be made well in advance of sales, new product decisions must anticipate both the future demand for products under development and the equipment required to produce such products. The combined company cannot be certain that it will be successful in selecting, developing, manufacturing and marketing new products or in enhancing existing products.

        The process of developing new high technology capital equipment products and services is complex and uncertain, and failure to anticipate customers' changing needs and emerging technological trends accurately and to develop or obtain appropriate intellectual property could significantly harm the combined company's results of operations. The combined company must make long-term investments and commit significant resources before knowing whether its predictions will eventually result in products that the market will accept. For example, FEI has invested significant resources in the development of 300 mm semiconductor wafer manufacturing technology. If 300 mm fabrication is not widely accepted or if the combined company fails to develop 300 mm products that are accepted by the marketplace, its long-term growth could be diminished. Similarly, Veeco has invested significant resources in the development of certain products utilizing physical vapor deposition technology which has been slow to gain customer acceptance. Further, after a product is developed, the combined company must be able to manufacture sufficient volumes quickly and at low costs. To accomplish this, it must accurately forecast volumes, mix of products and configurations that meet customer requirements, and it may not succeed.

23

        The combined company's quarterly operating results may fluctuate because of many factors, which would cause its stock price to fluctuate.

        Both Veeco's and FEI's net revenues and operating results have fluctuated in the past and the combined company's net revenues and operating results are likely to fluctuate significantly in the future on a quarterly and annual basis due to a number of factors, many of which are outside either company's control. Investors should not rely on the results of any one quarter or series of quarters as an indication of the combined company's future performance.

        It is likely that in some future quarter or quarters the combined company's operating results will be below the expectations of public market analysts or investors. In such event, the market price of the combined company's common stock may decline significantly.

        Because the combined company will have larger revenues and operations, third parties with potential litigation claims against either Veeco or FEI who decided not to pursue those claims against the individual companies may consider asserting those claims against the combined company, which could adversely affect its results of operations.

        The combined company is expected to have significantly greater revenues and assets than either Veeco or FEI individually, operations in more countries than either Veeco or FEI individually, and more employees than either Veeco or FEI individually. As a result, it can be expected that some third parties who believe that they have claims against Veeco or FEI, but who chose not to assert those claims because of the size of the individual companies, may now choose to pursue those claims against the larger combined company.

        The combined company cannot be certain that it will be able to compete successfully in its highly competitive industries.

        The industries in which the combined company will operate are intensely competitive. Established companies, both domestic and foreign, will compete with each of its product lines. Many of the combined company's competitors will have greater financial, engineering, manufacturing and marketing resources. A substantial investment is required by customers to install and integrate capital equipment into a production line. As a result, once a manufacturer has selected a particular vendor's capital equipment, Veeco and FEI believe that the manufacturer generally relies upon that equipment for the specific production line application and frequently will attempt to consolidate its other capital equipment requirements with the same vendor. Accordingly, if a particular customer selects a competitor's capital equipment, the combined company will expect to experience difficulty selling to that customer for a significant period of time. The combined company's ability to compete successfully will depend on a number of factors both within and outside the combined company's control, including:

        The combined company cannot be certain that it will be able to compete successfully in the future.

24

        The combined company could be subject to class action litigation due to stock price volatility, which, if it occurs, will distract management and result in substantial costs, and could result in judgments against the combined company.

        In the past, securities class action litigation has often been brought against companies following periods of volatility in the market price of their securities. The combined company may be the target of similar litigation in the future. Securities litigation could result in substantial costs and divert management's attention and resources, which could cause serious harm to the combined company's business, financial condition and results of operations.

        The combined company's revenues and selling, general and administrative expenses will suffer if it cannot continue to license or enforce the intellectual property rights on which its business will depend or if third parties assert that the combined company violates their intellectual property rights.

        Several of the combined company's competitors hold patents covering a variety of technologies to be included in some of its products. In addition, some of the combined company's customers may use its microelectronics products for applications that are similar to those covered by these patents. From time to time, Veeco, FEI and their respective customers have received correspondence from their competitors claiming that some of Veeco's or FEI's products, as the case may be, as used by their customers, may be infringing one or more of these patents. As of the date of this joint proxy statement/prospectus, none of these allegations has resulted in litigation. Competitors or others may, however, assert infringement claims against the combined company or its customers in the future with respect to current or future products or uses, and these assertions may result in costly litigation or require the combined company to obtain a license to use intellectual property rights of others. If claims of infringement are asserted against the combined company's customers, those customers may seek indemnification from the combined company for damages or expenses they incur.

        The combined company may also face greater exposure to claims of infringement in the future because PBE is no longer FEI's majority owner. As a result of PBE's reduction of ownership of FEI common stock in 2001, the combined company will not benefit from most of the Philips patent cross-licenses from which FEI benefited before that reduction.

        If the combined company becomes subject to infringement claims, it will evaluate its position and consider the available alternatives, which may include seeking licenses to use the technology in question or defending its position. These licenses, however, may not be available on satisfactory terms or at all. If the combined company is not able to negotiate the necessary licenses on commercially reasonable terms or successfully defend the combined company's position, it could have a material adverse effect on the combined company's business, prospects, financial condition and operating results.

        The combined company is exposed to the risks that third parties may violate its proprietary rights and the combined company's intellectual property rights may not be well protected in foreign countries.

        The combined company's success will depend on the protection of its proprietary rights. In the combined company's industry, intellectual property is an important asset that is always at risk of infringement. The combined company will incur costs to obtain and maintain patents and defend its intellectual property. The combined company will rely upon the laws of the United States and of other countries in which it develops, manufactures or sells products to protect its proprietary rights. However, these proprietary rights may not provide the competitive advantages that the combined company expects, or other parties may challenge, invalidate or circumvent these rights.

        Further, the combined company's efforts to protect its intellectual property may be less effective in some countries where intellectual property rights are not as well protected as in the United States. Many U.S. companies have encountered substantial problems in protecting their proprietary rights against infringement in foreign countries. Veeco derived approximately 50% of its sales from foreign countries in 2000, and approximately 46% of its sales from foreign countries in 2001. FEI derived approximately 58% of its sales from foreign countries in 2000, and approximately 57% of its sales from

25

foreign countries in 2001. If the combined company fails to adequately protect its intellectual property in these countries, it could be easier for its competitors to sell competing products.

        Infringement of the combined company's proprietary rights by a third party could result in lost market and sales opportunities for the combined company, as well as increased costs of litigation.

        The loss of key management or the combined company's inability to attract and retain sufficient numbers of managerial, engineering and other technical personnel could have a material adverse effect on its business.

        The combined company's continued success will depend, in part, upon key managerial, engineering and technical personnel as well as its ability to continue to attract and retain additional personnel. In particular, the combined company will depend on its President and Chief Executive Officer, Edward H. Braun, and its Chairman and Chief Strategy Officer, Vahé A. Sarkissian. The loss of key personnel could have a material adverse effect on the combined company's business, prospects, financial condition or operating results. The combined company may not be able to retain its key managerial, engineering and technical employees. The combined company's growth will be dependent on its ability to attract new highly skilled and qualified technical personnel, in addition to personnel that can implement and monitor its financial and managerial controls and reporting systems. Attracting qualified personnel is difficult, and the combined company cannot assure you that its recruiting efforts to attract and retain these personnel will be successful.

        After consummation of the merger, the combined company will have significant indebtedness. At June 30, 2002, on a pro forma basis after giving effect to the consummation of the merger, the combined company would have had total consolidated long-term debt (including current maturities) of approximately $413 million.

        The degree to which the combined company is leveraged could have important consequences to you including, but not limited to, the following:

        The ability of the combined company to pay interest and principal on its debt securities and to satisfy its other debt obligations and to make planned expenditures, will be dependent on its future operating performance, which could be affected by changes in economic conditions and other factors, including factors beyond its control. A failure to comply with the covenants and other provisions of its debt instruments could result in events of default under such instruments, which could permit acceleration of the debt under such instruments and in some cases acceleration of debt under other instruments that contain cross-default or cross-acceleration provisions. We believe that cash flow from operations will be sufficient to cover the combined company's debt service requirements and other requirements. However, if the combined company is at any time unable to generate sufficient cash flow from operations to service its indebtedness, it may be required to seek to renegotiate the terms of the instruments relating to that indebtedness, seek to refinance all or a portion of that indebtedness or to obtain additional financing. There can be no assurance that the combined company will be able to successfully renegotiate such terms, that any such refinancing would be possible or that any additional financing could be obtained on terms that are favorable or acceptable to it.

26

        The combined company may not be able to obtain sufficient affordable funds to fund its future needs for manufacturing capacity and research and development.

        The combined company will need to continue to make significant capital expenditures to continue and expand its operations and to enhance its manufacturing capability to keep pace with rapidly changing technologies. Also, the industries in which the combined company operates are characterized by the need for continued investment in research and development. If Veeco FEI fails to invest sufficiently in research and development, its products could become less attractive to existing and potential new customers. As a result of an emphasis on research and development and technological innovation, the combined company's operating costs may increase in the future. During the past few years, the markets for equity and debt securities have fluctuated significantly, especially with respect to technology-related companies, and during some periods offerings of those securities have been extremely difficult to complete. As a result, in the future the combined company may not be able to obtain the additional funds required to fund its operations and invest sufficiently in research and development on reasonable terms, or at all. Such a lack of funds could have a material adverse effect on the combined company's business, prospects, financial condition and operating results.

        The combined company will be subject to increased operational costs and other risks because PBE no longer owns a majority of FEI's common stock.

        Before FEI's most recent public offering of common stock in May 2001, PBE's ownership interest in FEI fluctuated within a few percentage points of 50% of FEI's outstanding shares and PBE and its affiliates provided various services for, and engaged in a variety of transactions with FEI, some of which were upon terms more favorable to FEI than otherwise attainable in the general marketplace. On June 30, 2002, PBE beneficially owned approximately 25% of FEI's common stock. Because PBE is no longer FEI's majority shareholder, some of the tangible and intangible benefits and arrangements previously provided to FEI by Philips have terminated and some of these are in the process of being terminated. In 2001, FEI paid Philips and its affiliates approximately $4.5 million for certain administrative and other services. FEI will not have completed the replacement of all of its arrangements with Philips by the closing of the merger, and in some of these areas the combined company may not be able to find replacement services at a similar or lower cost. Even if these services are available at a similar cost, indirect costs are associated with obtaining new vendors, including diversion of management time and resources.

        Some of the specific types of increased costs the combined company may incur in the future include the following:

27

        PBE will have significant influence on all combined company stockholder votes and may have different interests than other combined company's stockholders.

        PBE will own approximately 15% of the outstanding Veeco FEI common stock after the merger. As a result, PBE will have significant influence on matters submitted to the combined company's stockholders, including proposals regarding:

28

        In addition to its significant influence, PBE's interests may be significantly different from the interests of other owners of the combined company's common stock, holders of the combined company's options to purchase common stock and holders of the combined company's debt securities. Under the investor agreement, PBE will also have the right to nominate a member of the combined company's board of directors for a certain period of time.

        Terrorist acts and acts of war may seriously harm the combined company's business and revenues, costs and expenses and financial condition.

        Terrorist acts or acts of war (wherever located around the world) may cause damage or disruption to the combined company, its employees, facilities, partners, suppliers, distributors and customers, which could significantly impact its revenues, costs and expenses and financial condition. The terrorist attacks that took place in the United States on September 11, 2001 were unprecedented events that have created many economic and political uncertainties, some of which may materially harm the combined company's business and results of operations. The potential for future terrorist attacks, the national and international responses to terrorist attacks, and other acts of war or hostility have created many economic and political uncertainties, which could adversely affect the business and results of operations of the combined company in ways that cannot presently be predicted. The combined company will be largely uninsured for losses and interruptions caused by terrorist acts and acts of war.

        Unforeseen environmental costs could impact the future net earnings of the combined company.

        Some of the combined company's operations will use substances regulated under various federal, state and international laws governing the environment. The combined company could be subject to liability for remediation if it does not handle these substances in compliance with applicable laws. It will be the combined company's policy to apply strict standards for environmental protection to sites inside and outside the United States, even when not subject to local government regulations. The combined company will record a liability for environmental remediation and related costs when it considers the costs to be probable and the amount of the costs can be reasonably estimated.

        Veeco FEI's organizational documents will have anti-takeover provisions that might, among other things, discourage, prevent or delay a change of control of Veeco FEI that a holder of Veeco FEI stock might consider in its best interest.

        Veeco FEI's board of directors will continue to have the authority to issue up to 500,000 shares of "blank check" preferred stock and to fix the rights, preferences, privileges and restrictions, including voting rights, of these shares without any further vote or action by Veeco FEI's stockholders. The rights of the holders of any preferred stock that may be issued in the future may adversely affect the rights of the holders of Veeco FEI common stock. The issuance of the preferred stock, while providing Veeco FEI with desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire a majority of Veeco FEI's outstanding voting stock. This could delay, defer or prevent a change of control of Veeco FEI that a holder of Veeco FEI common stock might consider in its best interests. Furthermore, such preferred stock may have other rights including economic rights senior to Veeco FEI common stock, and as a result, the issuance of the preferred stock could have a material adverse effect on the market value of Veeco FEI common stock. Veeco FEI has no present plan to issue shares of preferred stock.

        Veeco FEI's board of directors will continue to be divided into three classes of directors with staggered terms. Directors will be elected to three-year terms and the term of one class of directors will expire each year. The existence of a classified board of directors is designed to provide continuity and stability to Veeco FEI's management, which results from directors serving for three-year, rather than one-year terms. The existence of a classified board of directors may make it more difficult for a third party to acquire control of Veeco FEI in certain instances. This could delay, defer or prevent a change of control that a holder of Veeco FEI common stock might consider in its best interest. Further, if

29

Veeco stockholders are dissatisfied with the policies and/or decisions of Veeco FEI's board of directors, the existence of a classified board of directors will make it more difficult for the stockholders to change the composition (and therefore the policies) of Veeco FEI's board of directors in a relatively short period of time.

        Veeco FEI will continue Veeco's rights plan, commonly called a "poison pill." This could make it more difficult for a third party to acquire control of Veeco FEI in certain circumstances. This could also delay, defer or prevent a change of control that a Veeco FEI stockholder might consider in its best interests.

        Also, certain other provisions in Veeco's Amended and Restated Certificate of Incorporation will continue to be in Veeco FEI's Amended and Restated Certificate of Incorporation and bylaws relating to:

which may delay, defer or prevent a takeover attempt that a holder of Veeco FEI common stock might consider in its best interest.

        Furthermore, Veeco FEI may in the future adopt other measures that may have the effect of delaying, deferring or preventing a change of control of Veeco FEI. Certain of these measures may be adopted without any further vote or action by the holders of Veeco FEI common stock.

        The data storage industry is a relatively new and developing market for FEI and may not develop as much as FEI expects.

        The data storage industry is a relatively new and developing market for FEI and may not develop as much as FEI expects. For 2001, net sales of FEI's products to the data storage industry accounted for approximately 12% of FEI's net product sales, and FEI expects sales to this industry to be an important contributing factor to future growth in FEI's total sales. The data storage industry is a newer market for FEI's products than the other markets that FEI serves and, as a result, involves greater uncertainties. These uncertainties could harm the combined company's business, financial condition and results of operations. For example, although FEI views the data storage market as a growth market, the market may never fully develop as FEI expects, or alternative technologies or tools may be introduced. In addition, the data storage market recently has experienced a significant amount of consolidation. As a result, FEI's customers in the data storage industry are becoming greater in size and fewer in number, so that the loss of any single customer would have a greater adverse impact upon the combined company's results of operations.

Risks Related to the Failure of Veeco's Stockholders to Approve the Change of Corporate Name Amendment to Veeco's Amended and Restated Certificate of Incorporation

        Veeco may be deemed to be in violation of contractual arrangements including the merger agreement.

        If Veeco's stockholders do not approve the proposed amendment to Veeco's Amended and Restated Certificate of Incorporation to change the name of Veeco Instruments Inc. to Veeco FEI Inc., then Veeco could be deemed to be in violation of contractual provisions in the merger agreement which, if deemed material, could give rise to FEI's right to terminate the merger agreement. In the case of such a termination by FEI, Veeco could be required to pay FEI's fees and expenses, up to $5 million, incurred in connection with the merger agreement and the merger.

SELECTED HISTORICAL AND UNAUDITED PRO FORMA
CONSOLIDATED FINANCIAL DATA OF VEECO AND FEI

        The following information is being provided to assist you in analyzing the financial aspects of the merger.

        The historical selected financial information for Veeco for the six months ended June 30, 2002 and 2001 was derived from the unaudited consolidated financial statements included in Veeco's quarterly report on Form 10-Q for the quarterly period ended June 30, 2002 incorporated by reference into this joint proxy statement/prospectus. The historical data presented for Veeco for the six months ended June 30, 2002 and 2001 is unaudited and, in the opinion of Veeco's management, includes all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of such data. Veeco's historical results for the six months ended June 30, 2002 are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2002. The historical selected statement of operations data for Veeco for the fiscal years ended December 31, 2001, 2000, 1999, 1998 and 1997 and the historical balance sheet data of Veeco as of December 31, 2001, 2000, 1999, 1998 and 1997 was derived from the historical audited consolidated financial statements of Veeco incorporated by reference into this joint proxy statement/prospectus.

        The historical selected financial information for FEI for the twenty-six weeks ended June 30, 2002 and July 1, 2001 was derived from the unaudited consolidated financial statements included in FEI's quarterly report on Form 10-Q for the quarterly period ended June 30, 2002 incorporated by reference in this joint proxy statement/prospectus. The historical data presented for FEI for the twenty-six weeks ended June 30, 2002 and July 1, 2001 is unaudited and, in the opinion of FEI's management, includes all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of such data. FEI's historical results for the twenty-six weeks ended June 30, 2002 are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2002. The historical selected statement of operations data for FEI for the fiscal years ended December 31, 2001, 2000 and 1999 and the historical consolidated balance sheet data of FEI as of December 31, 2001 and 2000 was derived from the historical audited consolidated financial statements of FEI incorporated by reference into this joint proxy statement/prospectus. The historical selected statement of operations data for FEI for the fiscal years ended December 31, 1998 and 1997 and the historical balance sheet data for FEI as of December 31, 1999, 1998 and 1997 have been derived from FEI's historical financial statements, which are not incorporated by reference into this joint proxy statement/prospectus.

        The selected unaudited pro forma consolidated financial data is based upon the historical consolidated financial statements and notes thereto (as applicable) of Veeco and FEI, which are incorporated by reference herein. The selected unaudited pro forma consolidated balance sheet data gives pro forma effect to the merger as if it had been consummated on June 30, 2002 and combines Veeco's June 30, 2002 unaudited consolidated balance sheet with FEI's June 30, 2002 unaudited consolidated balance sheet. The selected unaudited pro forma consolidated statements of operations data give pro forma effect to the merger as if it had been consummated on January 1, 2001 and combine Veeco's consolidated statement of operations for the year ended December 31, 2001 with FEI's consolidated statement of operations for the year ended December 31, 2001 and Veeco's unaudited consolidated statements of operations for the six months ended June 30, 2001 and 2002, respectively, with FEI's unaudited consolidated statements of operations for the twenty-six weeks ended July 1, 2001 and June 30, 2002, respectively. The pro forma adjustments are subject to change pending a final analysis of fair values of the assets acquired and liabilities assumed. The impact of these changes could be material.

        In addition, on September 17, 2001, a wholly-owned subsidiary of Veeco merged with and into Applied Epi, Inc. of St. Paul, Minnesota. As a result of that merger, Applied Epi became a wholly-owned subsidiary of Veeco. The selected unaudited pro forma consolidated statement of operations

31


data for the six months ended June 30, 2001 and for the year ended December 31, 2001 give effect to the acquisition of Applied Epi by Veeco as if it occurred on January 1, 2001.

        The selected unaudited pro forma consolidated financial data is derived from the unaudited pro forma consolidated financial statements included elsewhere herein and should be read in conjunction with those statements and notes thereto. See the section of this joint proxy statement/prospectus titled "Unaudited Pro Forma Consolidated Financial Statements." The selected unaudited pro forma consolidated financial data is based upon the estimates and assumptions set forth in the introduction and notes to the Unaudited Pro Forma Consolidated Financial Statements included elswhere herein. The pro forma adjustments (including estimates and assumptions) made in connection with the preparation of the pro forma information are preliminary and have been made solely for purposes of preparing such pro forma information for illustrative purposes necessary to comply with the disclosure requirements of the SEC. The selected unaudited pro forma consolidated financial data does not purport to be indicative of the results of operations for future periods or the consolidated financial position or results that actually would have been realized for the periods presented had Veeco and FEI been a single entity during these periods. The selected unaudited pro forma consolidated financial data does not give effect to any synergies, cost savings, or integration costs that may result from the integration of Veeco's and FEI's businesses. Costs associated with the Veeco FEI transaction related to restructuring and integration have not yet been determined. In addition, FEI's operating costs have increased and may further increase due to the termination (and expected termination) of some of the tangible and intangible benefits and arrangements provided to FEI by Philips. Certain of these benefits and arrangements terminated prior to June 30, 2002 and a portion of these increased costs resulting therefrom have already been incurred by FEI. FEI has also received payments described herein from Philips, which have offset certain of these increased costs and have been recorded by FEI as a reduction in costs and operating expenses. The selected unaudited pro forma consolidated financial data excludes the effect of a portion of the additional operating costs which may be incurred in connection with the termination of certain arrangements between FEI and Philips, which costs cannot be reasonably estimated at this time. In addition, the selected unaudited pro forma consolidated data exclude the effect of a portion of the increased additional pension costs of FEI which will be incurred in connection with FEI's new collective bargaining agreements that took effect September 1, 2001. For more information concerning these additional costs, see the sections titled "Risk Factors—The combined company will be subject to increased operational costs and other risks because PBE no longer owns a majority of FEI's common stock" beginning on page 27 and "Relationship with Philips" beginning on page 100.

        The following information should be read in conjunction with the historical financial statements and related notes contained in the annual, quarterly and other reports filed by Veeco and FEI with the SEC. See the section titled "Where You Can Find More Information" beginning on page 134.

During December 2001, Veeco classified its industrial measurement operating segment as a discontinued operation. The Consolidated Statements of Operations and Balance Sheet data for all years presented have been restated to reflect this. See Note 7 to the consolidated financial statements included in Veeco's Annual Report on Form 10-K for the fiscal year ended December 31, 2001, incorporated by reference herein.

(2)
Prior to Veeco's merger with CVC, Inc. on May 5, 2000, CVC's fiscal year end was September 30. Therefore the Statement of Operations data for all years presented through 1999 was derived from CVC's financial statements for the respective twelve month periods ended September 30. In addition, the Balance Sheet Data through 1999 was derived from CVC's September 30 balance sheets.

(3)
Prior to Veeco's merger with Ion Tech, Inc. on November 4, 1999, Ion Tech's fiscal year end was June 30. In connection with the merger, the financial results of Ion Tech were recast for 1998 to conform to Veeco's December 31 year end. For the year ended December 31, 1997, historical results include those for Ion Tech's fiscal year ended June 30, 1998, thus resulting in six months of 1998 activity in the 1997 results of operations.

(4)
Veeco incurred merger and restructuring charges of $28.2 million during the year ended December 31, 2001. Of these charges, $13.6 million related to the write-off of inventory (included in cost of sales), $8.2 million related to the write-off of purchased in-process technology ($7.0 million resulting from the acquisition of Applied Epi, Inc. and $1.2 million from the acquisition of Thermo Microscopes Corp.), $3.0 million represented restructuring costs and $3.4 million was for the write-down of long-lived assets. See Note 7 to Veeco's consolidated financial statements included in Veeco's Annual Report on Form 10-K for the fiscal year ended December 31, 2001, incorporated by reference herein.

(5)
Veeco incurred merger and reorganization charges of $33.3 million during the year ended December 31, 2000, of which $33.0 million related to the merger with CVC. Of these charges, $15.3 million related to a write-off of inventory (included in cost of sales), $14.0 million represented merger and reorganization costs (of which $9.2 million related to investment banking, legal and other one-time transaction costs and $4.8 million pertained to duplicate facility and personnel costs) and $3.7 million was for the write-off of long-lived assets. See Note 2 to Veeco's consolidated financial statements included in Veeco's Annual Report on Form 10-K for the fiscal year ended December 31, 2001, incorporated by reference herein.

(6)
Veeco incurred restructuring expense of $1.9 million during the six months ended June 30, 2002 related to the cost reduction efforts that were initiated during the fourth quarter of 2001 and the first quarter of 2002. Veeco incurred restructuring expenses of $1.0 million during the six months ended June 30, 2001.

(7)
During 1999, Veeco recorded charges of $2.6 million related to merger expenses in connection with the merger with Ion Tech. In 1998, Veeco recorded merger and reorganization expenses of $7.5 million related to the merger with Digital Instruments, Inc. During 1997, Veeco incurred $2.3 million of merger expenses in conjunction with the merger with Wyko Corporation.

(8)
During 1999, Veeco recorded a $2.5 million charge related to the write-off of purchased in-process technology ($1.3 million related to the acquisition of OptiMag, Inc. and $1.2 million related to CVC's acquisition of Commonwealth Scientific Corporation). During 1997, Veeco recorded a $4.2 million charge related to the write-off of purchased in-process technology in connection with the acquisition of physical vapor deposition assets.

(9)
Effective January 1, 2000, Veeco changed its method of accounting for revenue recognition in accordance with Staff Accounting Bulletin No. 101. See Note 1 to the audited consolidated financial statements contained in Veeco's Annual Report on Form 10-K for the fiscal year ended December 31, 2001, incorporated by reference herein.

(10)
Veeco adopted Staff Accounting Bulletin No. 101 effective January 1, 2000. Had this adoption taken place on January 1, 1998, net income, net income per common share and diluted net income per common share on a pro forma basis for 1999 and 1998 would have been as follows:

 
   1999
   1998
Net income   $ 13,695   $ 12,682
Net income per common share   $ 0.66   $ 0.68
Diluted net income per common share   $ 0.64   $ 0.65

        On or about                             , 2002, this joint proxy statement/prospectus, which includes a notice satisfying the applicable requirements of Delaware law, is being mailed to all Veeco stockholders of record as of the Veeco record date.

Voting and Solicitation

        At the Veeco special meeting, each Veeco stockholder will be entitled to one vote for each share of Veeco common stock held by it. Under Veeco's bylaws, the presence of the holders of at least 50% of all of the Veeco common stock entitled to vote, whether present in person or by proxy, at Veeco's special meeting, shall constitute a quorum for the transaction of business at Veeco's special meeting.

        Under applicable rules of The Nasdaq National Market, if a quorum is present, the affirmative vote of a majority of the votes cast, whether in person or by proxy, at Veeco's special meeting, is required to approve the issuance of Veeco common stock in connection with the merger.

THE MERGER

        This section of the joint proxy statement/prospectus describes the proposed merger. While FEI and Veeco believe that the description covers the material terms of the merger and the related transactions, this summary may not contain all of the information that is important to you. You should read this entire joint proxy statement/prospectus, including its Appendices and the other documents referred to herein, carefully for a more complete understanding of the merger.

Background of the Merger

        The merger agreement and the terms and conditions of the merger are the result of negotiations between representatives of Veeco and FEI. The following summary describes the background of these negotiations.

        From time to time, both Veeco and FEI have conducted preliminary discussions with numerous merger and acquisition candidates. Before October 2001, Edward H. Braun, Chairman, Chief Executive Officer and President of Veeco, and Vahé A. Sarkissian, Chairman, Chief Executive Officer and President of FEI, were familiar with one another and had come into contact with one another at industry trade shows, various conventions and in various other circumstances. In addition, prior to his employment at FEI, Mr. Sarkissian provided consulting services to Veeco on certain discrete projects.

        On several occasions over the past several years, Mr. Braun and Mr. Sarkissian had discussed the possibility of a business combination or strategic relationship involving Veeco and FEI. However, on each occasion, these discussions were terminated and did not result in any further actions relating to any such business combination or strategic relationship.

        During October and November 2001, Mr. Braun and Mr. Sarkissian had preliminary conversations and exchanged general information about Veeco's and FEI's businesses and the general possibility of a business combination was suggested. During December 2001 and January 2002, these discussions continued and Messrs. Braun and Sarkissian agreed to continue their discussions regarding a proposed strategic combination of Veeco and FEI.

        On January 21 and 22, 2002, Mr. Braun and Mr. Sarkissian met in person in San Jose, California. The meeting focused on the two companies' business operations and strategy, whether a cultural fit existed between the two companies and how the two companies could be integrated. At this meeting, Mr. Braun made a proposal to Mr. Sarkissian regarding a potential business combination involving Veeco and FEI.

        In January 2002, Veeco retained Salomon Smith Barney Inc. to act as its financial advisor in connection with a possible business combination with FEI and to assist Veeco in evaluating the proposed combination. Salomon Smith Barney had previously, from time to time, assisted Veeco in evaluating potential strategic relationships.

        On January 25, 2002, FEI engaged Credit Suisse First Boston to act as its financial advisor in connection with a potential strategic transaction with Veeco.

        On January 25, 2002, at its regularly scheduled board meeting, the Veeco board of directors discussed the potential transaction with FEI, among other things. The board determined that management should continue to evaluate and pursue the potential transaction with FEI.

        On February 28, 2002, Veeco and FEI entered into a Mutual Confidentiality Agreement in connection with their ongoing negotiations and due diligence activities.

        On March 16, 2002, the FEI board of directors met and discussed, among other things, the possibility of entering into a transaction with Veeco. The board considered background materials on Veeco presented by management, including information on its business and markets, historical financial results and the trading history of its common stock. The FEI board of directors also discussed other potential merger or acquisition candidates and FEI's prospects as a stand-alone entity. Based on its

42



discussions regarding potential alternatives, the board of directors determined that FEI management should continue to evaluate and pursue the business combination with Veeco.

        On March 18 and 19, 2002, Messrs. Braun and Sarkissian met in New York, New York to further discuss FEI's and Veeco's businesses, the markets served by each company and how FEI and Veeco might complement each other as part of a combined entity. The parties also discussed the structure of a potential transaction, as well as roles of senior officers, the potential exchange ratio for the transaction, the potential management of the combined company and other general matters.

        Between March 15 and April 9, 2002, discussions took place between certain of Veeco's and FEI's senior management personnel during which they reviewed the product offerings, markets served and technologies of each company, as well as the financial results and condition of each business. Also during this period, representatives of Veeco's and FEI's senior management engaged in discussions relating to the terms and conditions of a possible business combination. In addition, Veeco's outside legal counsel, Kaye Scholer LLP, had discussions with FEI's outside legal counsel, Wilson Sonsini Goodrich & Rosati, regarding the scope of the mutual due diligence to be conducted.

        In March 2002, Veeco retained Ernst & Young LLP to perform certain accounting and financial due diligence services for it in connection with the proposed merger.

        The discussions in late March and early April led to meetings involving members of senior management of each of Veeco and FEI and their outside legal and financial advisors in San Francisco, California on April 10 and 11, 2002. The main purpose of these meetings was for the management of each of the companies to meet each other and to become familiar with the business and operations of the other. At the meetings, members of management of each of Veeco and FEI presented an overview highlighting their respective operations, products, technology, research and development efforts and results of operations and financial condition. Members of both Veeco's and FEI's outside legal and financial advisors were also present at the meetings.

        Between April 10 and July 11, 2002:

        On April 15, 2002, Kaye Scholer LLP delivered an initial draft of the merger agreement to FEI and Wilson Sonsini Goodrich & Rosati. Also on April 15, 2002, Merchant & Gould, LLP was retained by Veeco to conduct due diligence with respect to the intellectual property held and/or licensed by FEI.

        On April 18, 2002, in a special meeting of the FEI board of directors, FEI management, Wilson Sonsini Goodrich & Rosati and Credit Suisse First Boston reviewed with the FEI board of directors the transaction terms proposed by Veeco. In addition, Wilson Sonsini Goodrich & Rosati reviewed with the board of directors their fiduciary duties in connection with the proposed transaction. FEI's board of directors considered the proposed transaction and determined that management should continue to evaluate and pursue the potential business combination.

Veeco's Reasons for the Merger

        Veeco's board of directors believes that the merger is in the best interests of Veeco's stockholders and that the terms of the merger are fair, from a financial point of view, to Veeco and Veeco's stockholders. Veeco's board of directors came to its conclusion based upon a number of factors including the current financial condition and results of operations, as well as the prospects and future strategy, of Veeco and the risks involved in achieving those prospects and objectives without a strategic partner, and the factors described below. In particular, the Veeco board of directors, in its deliberations, focused on the current and expected trends in the semiconductor and data storage industries generally.

        Veeco's board of directors believes that the merger is consistent with Veeco's objectives and strategies to gain access to new markets, technologies and products in order to maintain and expand its

46



competitive position. Veeco's board of directors also believes that the merger will set the stage for increased levels of profitability as the company continues to grow and will create a stronger company, both from a financial and an operational standpoint.

        In determining to enter into the merger agreement, Veeco's board of directors considered that the merger involving Veeco and FEI would create a combined company that would have had combined 2001 revenues of $825 million and that Veeco and FEI together would have been the third-largest U.S. provider of semiconductor metrology equipment, the sixth-largest U.S. company serving the semiconductor equipment industry, and a leader in 3D metrology, a market which is projected to grow at an annual rate of 25% per year for the next three years. Further, the Veeco board of directors considered that the combined company would have a more favorable product mix consisting of approximately two-thirds metrology equipment and one-third process equipment, contrasted with Veeco's product mix, which, for its most recent fiscal year, had $172 million in metrology product revenue and $277 million in process equipment revenue. The Veeco board of directors also considered that the size of the metrology market is expected to increase to nearly $15 billion by the year 2004, making it the fastest growth area in semiconductor equipment, and that the improved product mix likely would lead to improvements in Veeco's gross margins, possibly enabling the combined company to achieve Veeco's long-term 50% gross margin target. The Veeco board of directors also considered the complementary nature of Veeco's and FEI's technologies. Additionally, the Veeco board of directors considered the potential of annual cost savings of approximately $8 to $10 million that could result from the merger from near-term selling, general and administrative synergies and synergistic cost savings resulting from the integration of Veeco's and FEI's worldwide field sales and service organizations.

        In rendering its decision, Veeco's board of directors, in addition to considering the anticipated benefits described above, consulted with Veeco's management, outside legal counsel and financial advisor and considered many other potential material factors that it believed made the merger advisable and that could contribute to the long-term success of Veeco, including that the merger would:

        Veeco's board of directors also considered the following:

47

        Veeco's board of directors also considered that the merger was expected, based upon its evaluation of the prospects of the companies, to be accretive to industry analysts' consensus estimates for Veeco FEI's pro forma earnings per share for the year ending December 31, 2003.

        Veeco's board of directors also considered the potential risks and disadvantages of the merger, including, but not limited to, the following:

48

        The foregoing discussion of the information and factors considered by the Veeco board of directors is not intended to be exhaustive but is believed to include the material factors considered by the Veeco board of directors in connection with its review of the proposed merger. In view of the wide variety of factors considered in connection with its evaluation of the merger, Veeco's board of directors did not find it practicable to, and did not, quantify or otherwise attempt to assign relative weights to different factors considered in reaching its determination. Rather, the Veeco board of directors viewed its position and recommendations as being based on the totality of the information presented to, and considered by, the Veeco board of directors. In addition, individual members of Veeco's board of directors may have given different weights to different factors. All of the factors described above were carefully considered by Veeco's board of directors. Based on the above-described analysis, Veeco's board of directors has determined that the terms of the merger are advisable, consistent with and in furtherance of the long-term business strategy of Veeco and fair to, and in the best interests of, Veeco and Veeco's stockholders and has made the recommendation set forth below.

FEI's Reasons for the Merger

        The FEI board of directors approved the merger agreement and the transactions contemplated by the merger agreement because it determined that the combined company would have the potential to realize a stronger competitive position and improved long-term operating and financial results. The FEI board of directors came to its conclusion after considering a number of factors both for and against recommending the merger as described below.

        During the course of its deliberations, FEI's board of directors considered a number of factors that it believed made the merger advisable and could contribute to the long-term success of the combined company. These factors include the potential that the merger will:

        FEI's board of directors further considered:

        In making its ultimate determinations to enter into the merger agreement, the FEI board of directors also considered the potential risks and disadvantages of the merger, including, but not limited to, the following:

        In view of the wide variety of factors considered in connection with its evaluation of the merger, the FEI board of directors did not find it practicable to, and did not, quantify or otherwise attempt to assign relative weights to different factors considered in reaching its determination. In addition,

50

individual members of FEI's board of directors may have given different weights to different factors and may have considered other factors. The foregoing list of factors is not exhaustive.

Recommendation of Veeco's Board of Directors

        Veeco's board of directors unanimously has approved the merger, the merger agreement and the transactions contemplated thereby and has determined that the merger is advisable, consistent with and in furtherance of the long-term business strategy of Veeco and fair to, and in the best interests of, Veeco and its stockholders and has determined that the proposed amendments to Veeco's Amended and Restated Certificate of Incorporation to increase the authorized shares of Veeco's common stock and to change the name of Veeco Instruments Inc. to Veeco FEI Inc. and the proposed amendment to Veeco's First Amended and Restated Employee Stock Purchase Plan are advisable. After careful consideration, the Veeco board of directors unanimously recommends that Veeco stockholders vote "FOR" approval of the issuance of Veeco common stock in the merger, "FOR" the approval of the amendments to Veeco's Amended and Restated Certificate of Incorporation to increase the authorized shares of Veeco's common stock from 60,000,000 shares to 175,000,000 shares and to change the name of Veeco Instruments Inc. to Veeco FEI Inc. and "FOR" the approval of the amendment to Veeco's First Amended and Restated Employee Stock Purchase Plan to increase the number of shares of Veeco common stock issuable under the plan from 250,000 shares to 750,000 shares. As of the Veeco record date, members of Veeco's board of directors and management of Veeco held (together with entities with which they are affiliated), in the aggregate, approximately 0.4% of the outstanding Veeco common stock.

Recommendation of FEI's Board of Directors

        FEI's board of directors unanimously has approved the merger, the merger agreement and the transactions contemplated thereby and has determined that the merger is advisable, consistent with and in furtherance of the long-term business strategy of FEI and fair to, and in the best interests of, FEI and its shareholders. After careful consideration, FEI's board of directors unanimously recommends that FEI shareholders vote "FOR" the approval of the merger. As of the FEI record date, members of FEI's board of directors and management of FEI held (together with entities with which they are affiliated) in the aggregate, approximately 26.43% of the outstanding FEI common stock.

Opinion of Veeco's Financial Advisor

        Veeco retained Salomon Smith Barney Inc. to act as its financial advisor in connection with the proposed merger. In connection with this engagement, Veeco requested that Salomon Smith Barney evaluate the fairness, from a financial point of view, to Veeco of the exchange ratio provided for in the merger. On July 9, 2002, at a meeting of the Veeco board of directors held to evaluate the proposed merger, Salomon Smith Barney delivered to the Veeco board of directors an oral opinion, which opinion was confirmed by delivery of a written opinion dated July 11, 2002, the date of the merger agreement, to the effect that, as of that date and based on and subject to the matters described in its opinion, the exchange ratio was fair, from a financial point of view, to Veeco.

        In arriving at its opinion, Salomon Smith Barney:

51

        In rendering its opinion, Salomon Smith Barney assumed and relied, without independent verification, on the accuracy and completeness of all financial and other information and data publicly available or furnished to or otherwise reviewed by or discussed with it. With respect to financial forecasts and other information and data relating to Veeco and FEI provided to or otherwise discussed with Salomon Smith Barney, the managements of Veeco and FEI advised Salomon Smith Barney that the forecasts and other information and data were reasonably prepared on bases reflecting the best currently available estimates and judgments of the managements of Veeco and FEI as to the future financial performance of Veeco and FEI and the potential strategic implications and operational benefits anticipated to result from the merger, including the amount, timing and achievability of those strategic implications and operational benefits.

        Salomon Smith Barney assumed, with Veeco's consent, that 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 and consents for the merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on Veeco or FEI or the contemplated benefits of the merger. Salomon Smith Barney also assumed, with Veeco's consent, that the merger will be treated as a tax-free reorganization for federal income tax purposes. Salomon Smith Barney's opinion relates to the relative values of Veeco and FEI. Salomon Smith Barney did not express any opinion as to what the value of the Veeco common stock actually will be when issued in the merger or the prices at which the FEI common stock will trade or otherwise be transferable at any time. Salomon Smith Barney did not make and was not provided with an independent evaluation or appraisal of the assets or liabilities, contingent or otherwise, of Veeco or FEI, and Salomon Smith Barney did not make any physical inspection of the properties or assets of Veeco or FEI.

        Salomon Smith Barney expressed no view as to, and its opinion does not address the relative merits of the merger as compared to any alternative business strategies that might exist for Veeco or the effect of any other transaction in which Veeco might engage. Salomon Smith Barney's opinion was necessarily based on information available, and financial, stock market and other conditions and circumstances existing and disclosed to Salomon Smith Barney, as of the date of its opinion. Although Salomon Smith Barney evaluated the exchange ratio from a financial point of view, Salomon Smith Barney was not asked to and did not recommend the specific consideration payable in the merger, which was determined through negotiations between Veeco and FEI. Veeco imposed no other instructions or limitations on Salomon Smith Barney with respect to the investigations made or procedures followed by Salomon Smith Barney in rendering its opinion.

        The full text of Salomon Smith Barney's written opinion dated July 11, 2002, which describes the assumptions made, matters considered and limitations on the review undertaken, is attached to this joint proxy statement/prospectus as Appendix E and is incorporated into this joint proxy statement/prospectus by reference. You should read this opinion carefully and in its entirety in

52

connection with this joint proxy statement/prospectus. Salomon Smith Barney's opinion is directed to the Veeco board of directors and relates only to the fairness of the exchange ratio from a financial point of view, does not address any other aspect of the merger or any related transaction and does not constitute a recommendation to any stockholder with respect to any matters relating to the proposed merger.

        In preparing its opinion, Salomon Smith Barney performed a variety of financial and comparative analyses, including those described below. The summary of these analyses is not a complete description of the analyses underlying Salomon Smith Barney's opinion. The preparation of a fairness opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a fairness opinion is not readily susceptible to summary description. Accordingly, Salomon Smith Barney believes that its analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying its analyses and opinion.

        In its analyses, Salomon Smith Barney considered industry performance, general business, economic, market and financial conditions and other matters existing as of the date of its opinion, many of which are beyond the control of Veeco and FEI. No company, business or transaction used in those analyses as a comparison is identical to Veeco, FEI or the proposed merger, and an evaluation of those analyses is not entirely mathematical. Rather, the analyses involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies or business segments analyzed.

        The estimates contained in Salomon Smith Barney's analyses and the valuation ranges resulting from any particular analysis 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 its analyses. In addition, analyses relating to the value of businesses or securities do not necessarily purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold. Accordingly, Salomon Smith Barney's analyses and estimates are inherently subject to substantial uncertainty.

        Salomon Smith Barney's opinion and analyses were only one of many factors considered by the Veeco board of directors in its evaluation of the merger and should not be viewed as determinative of the views of the Veeco board of directors or management with respect to the exchange ratio or the proposed merger.

        The following is a summary of the material financial analyses, each of which is a standard valuation methodology customarily undertaken in transactions of this type, performed by Salomon Smith Barney in connection with the rendering of its opinion dated July 11, 2002. The financial analyses summarized below include information presented in tabular format. In order to fully understand Salomon Smith Barney's financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data in the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Salomon Smith Barney's financial analyses.

        Selected Companies Analysis.    Salomon Smith Barney performed a selected companies analysis in order to derive an implied exchange ratio reference range for FEI common stock based on selected implied trading multiples of publicly traded companies in Veeco's and FEI's industry. In this analysis, using publicly available information, Salomon Smith Barney reviewed the market values and trading multiples of Veeco, FEI and the following 11 selected publicly held companies in the metrology and

53

process control industry and the semiconductor capital equipment industry, in the later case, focusing on companies with market capitalizations of more than $1.0 billion:

 
   Metrology and Process Control
    
   Large Cap
Semiconductor Capital Equipment
•   KLA-Tencor Corporation   •   Applied Materials, Inc.
•   Nanometrics Incorporated   •   ASML Holding N.V.
•   Rudolph Technologies, Inc.   •   Axcelis Technologies, Inc.
•   Therma-Wave, Inc.   •   KLA-Tencor Corporation
•   Zygo Corporation   •   Lam Research Corporation
        •   Novellus Systems, Inc.
        •   Varian Semiconductor Equipment Associates, Inc.

        All multiples were based on closing stock prices on July 8, 2002. Estimated financial data for the selected companies were based on publicly available research analysts' estimates. Estimated financial data for Veeco and FEI were based on, in the case of Veeco, internal estimates of Veeco's management and, in the case of FEI, internal estimates of FEI's management. Salomon Smith Barney reviewed firm values, calculated as equity value plus straight and convertible debt, straight and convertible preferred stock and minority interests, less cash and equity in unconsolidated affiliates, as a multiple of calendar years 2002 and 2003 estimated revenues and calendar year 2003 estimated earnings before interest, taxes, depreciation and amortization, commonly referred to as EBITDA. Salomon Smith Barney also reviewed equity market values as a multiple of calendar years 2002 and 2003 estimated earnings per share, commonly referred to as EPS. Salomon Smith Barney then applied a range of selected multiples derived from the selected companies to corresponding financial data of Veeco and FEI in order to derive implied equity reference ranges for each of Veeco and FEI. These implied equity reference ranges were then used to derive an implied exchange ratio reference range. This analysis indicated the following implied exchange ratio reference range, as compared to the exchange ratio provided for in the merger:

Implied Exchange
Ratio Reference Range
   Merger
Exchange Ratio
0.88x — 2.32x   1.355x

        Precedent Transactions Analysis.    Salomon Smith Barney performed a precedent transactions analysis in order to derive an implied exchange ratio reference range for FEI common stock based on selected aggregate transaction values and implied transaction multiples in mergers and acquisition transactions involving other companies in Veeco's and FEI's industry. In this analysis, Salomon Smith Barney reviewed the aggregate transaction values and implied transaction multiples in the following nine selected merger and acquisition transactions in the semiconductor capital equipment industry:

 
   Acquiror
    
   Target
•   Applied Materials, Inc.   •   Etec Systems, Inc.
•   ASM Lithography Holding N.V.   •   Silicon Valley Group, Inc.
•   Brooks Automation, Inc.   •   PRI Automation, Inc.
•   KLA Instruments, Inc.   •   Tencor Instruments, Inc.
•   Kulicke & Soffa Industries, Inc.   •   Cerprobe Corporation
•   Mattson Technology, Inc.   •   CFM Technologies, Inc.
•   MKS Instruments, Inc.   •   Applied Science & Technology, Inc.
•   Novellus Systems, Inc.   •   GaSonics International Corporation
•   Veeco   •   CVC, Inc.

        All multiples for the selected transactions were based on publicly available information at the time of announcement of the relevant transaction. Salomon Smith Barney reviewed transaction values in the selected transactions as a multiple of latest 12 months revenue and equity market values in the selected

54

transactions as a multiple of latest 12 months EPS. Salomon Smith Barney then applied a range of selected multiples derived from the selected companies to corresponding financial data of Veeco and FEI in order to derive implied equity reference ranges for each of Veeco and FEI. These implied equity reference ranges were then used to derive an implied exchange ratio reference range. This analysis indicated the following implied exchange ratio reference range, as compared to the exchange ratio provided for in the merger:

Implied Exchange
Ratio Reference Range
   Merger
Exchange Ratio
0.73x — 1.75x   1.355x

        Salomon Smith Barney also derived an implied exchange ratio reference range based upon the implied equity reference range for FEI as derived above, on the one hand, and the equity market value for Veeco based on the closing price of Veeco common stock on July 8, 2002, on the other hand. This analysis indicated the following implied exchange ratio reference range, as compared to the exchange ratio provided for in the merger:

Implied Exchange
Ratio Reference Range
   Merger
Exchange Ratio
0.93x — 1.48x   1.355x

        Contribution Analysis.    Salomon Smith Barney performed a contribution analysis in order to derive an implied exchange ratio reference range for FEI common stock based on the relative contributions of Veeco and FEI of certain operational metrics to the combined company. In this analysis, Salomon Smith Barney reviewed the relative contributions of Veeco and FEI to the EBITDA, net income and earnings before interest, taxes and amortization of the combined company for estimated calendar years 2002 and 2003. Estimated financial data for Veeco and FEI were based on, in the case of Veeco, internal estimates of Veeco's management and, in the case of FEI, internal estimates of FEI's management. Salomon Smith Barney then derived an implied exchange ratio reference range based on the relative contributions of each of Veeco and FEI for each metric reviewed. This analysis indicated the following implied exchange ratio reference range, as compared to the exchange ratio provided for in the merger:

Implied Exchange
Ratio Reference Range
   Merger
Exchange Ratio
1.42x — 2.54x   1.355x

        Historical Exchange Ratio Analysis.    Salomon Smith Barney performed an historical exchange ratio analysis in order to compare the historical exchange ratio of FEI common stock to the implied exchange ratio in the merger. In this analysis, Salomon Smith Barney reviewed the ratio of the closing price of Veeco common stock to the closing price of FEI common stock on July 8, 2002 and the high, low and average of the daily ratios of the closing prices of Veeco common stock and FEI common stock over the 12-month, 90-day, 60-day and 30-day trading periods ended July 8, 2002. This analysis indicated the following, as compared to the exchange ratio provided for in the merger:

Period

July 8, 2002   0.940x

 
 
High
 
Average
 
Low
Last 12 months   1.236x   0.988x   0.821x

        Pro Forma Merger Analysis.    Salomon Smith Barney performed a pro forma merger analysis in order to determine whether the merger would be accretive or dilutive to Veeco's estimated cash EPS. In this analysis, Salomon Smith Barney reviewed the potential pro forma effect of the merger on Veeco's cash EPS for estimated calendar years 2002 and 2003, both before and after giving effect to potential cost savings or other synergies that may result from the merger. Estimated financial data for Veeco and FEI were based on, in the case of Veeco, internal estimates of Veeco's management and, in the case of FEI, internal estimates of FEI's management. For purposes of this analysis, Salomon Smith Barney assumed a 35% tax rate and aggregate transaction costs for the merger of approximately $20 million, based on the estimates of the managements of Veeco and FEI. In addition, with Veeco's consent, for purposes of this analysis, Salomon Smith Barney assumed that outstanding convertible debt was not converted into common stock. Based on the exchange ratio provided for in the merger, this analysis indicated that the merger could be accretive to Veeco's estimated cash EPS in each of the periods reviewed, both before and after giving effect to potential cost savings or other synergies that may result from the merger. The actual results achieved by the combined company may vary from projected results and the variations may be material.

        Other Factors.    In the course of preparing its opinion, Salomon Smith Barney also reviewed and considered other information and data, including:

        Miscellaneous.    Under the terms of its engagement, Veeco has agreed to pay Salomon Smith Barney an aggregate fee of $8,500,000 for its financial advisory services in connection with the merger. Veeco also has agreed to reimburse Salomon Smith Barney for reasonable travel and other out-of-pocket expenses incurred by Salomon Smith Barney in performing its services, including the reasonable fees and expenses of its legal counsel, and to indemnify Salomon Smith Barney and related persons against liabilities, including liabilities under the federal securities laws, arising out of its engagement.

        Salomon Smith Barney and its affiliates in the past have provided investment banking and financial services to Veeco unrelated to the proposed merger for which Salomon Smith Barney and its affiliates have received approximately $2,800,000 in fees during the past two years. In the ordinary course of business, Salomon Smith Barney and its affiliates may actively trade or hold the securities of Veeco and FEI for their own account or for the account of customers and, accordingly, may at any time hold a long or short position in these securities. In addition, Salomon Smith Barney and its affiliates, including Citigroup Inc. and its affiliates, may maintain relationships with Veeco, FEI and their affiliates.

        Salomon Smith Barney is an internationally recognized investment banking firm and was selected by Veeco based on its reputation, experience and familiarity with Veeco and its business. Salomon Smith Barney regularly engages in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes.

Opinion of FEI's Financial Advisor

        FEI retained Credit Suisse First Boston to act as its financial advisor in connection with the merger. In connection with Credit Suisse First Boston's engagement, FEI requested that Credit Suisse First Boston evaluate the fairness, from a financial point of view, of the merger exchange ratio to holders of FEI common stock, other than PBE and its affiliates. On July 10, 2002, the FEI board of directors met to review the proposed merger and the terms of the merger agreement. During this meeting, Credit Suisse First Boston reviewed with the FEI board of directors certain financial analyses, as described below, and rendered its oral opinion to the FEI board of directors, subsequently confirmed in writing on July 11, 2002, that, as of the date of its opinion and based upon and subject to the various considerations set forth in the Credit Suisse First Boston opinion, the merger exchange ratio was fair, from a financial point of view, to holders of FEI common stock, other than PBE and its affiliates.

        The full text of the Credit Suisse First Boston opinion, which sets forth, among other things, assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken by Credit Suisse First Boston in rendering its opinion, is attached as Appendix D to this joint proxy statement/prospectus and is incorporated by reference in its entirety. FEI shareholders are urged to, and should, read the Credit Suisse First Boston opinion carefully and in its entirety. The Credit Suisse First Boston opinion addresses only the fairness, from a financial point of view, of the merger exchange ratio to holders of FEI common stock, other than PBE and its affiliates, as of the date of the Credit Suisse First Boston opinion, and does not constitute a recommendation to any shareholder as to how such shareholder should vote or act on any matter relating to the merger. The summary of the Credit Suisse First Boston opinion in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of the Credit Suisse First Boston opinion.

        In connection with its opinion, Credit Suisse First Boston, among other things,

        In connection with its review, Credit Suisse First Boston did not assume any responsibility for independent verification of any of the foregoing information and relied on such information being complete and accurate in all material respects. With respect to the publicly available financial forecasts that Credit Suisse First Boston reviewed, the managements of FEI and Veeco advised Credit Suisse First Boston, and Credit Suisse First Boston assumed, that such forecasts represent reasonable estimates and judgments as to the future financial performance of FEI and Veeco, respectively. With respect to the non-publicly available financial forecasts that Credit Suisse First Boston reviewed, the managements of FEI and Veeco advised Credit Suisse First Boston, and Credit Suisse First Boston assumed, that such forecasts represent the best currently available estimates and judgments of the managements of FEI and Veeco as to the future financial performance of FEI and Veeco, respectively.

57

In addition, Credit Suisse First Boston relied upon, without independent verification, the assessments of the managements of FEI and Veeco as to:

        The management of FEI informed Credit Suisse First Boston, and Credit Suisse First Boston assumed, that the merger will be treated as a tax-free reorganization for federal income tax purposes. Credit Suisse First Boston also assumed, with FEI's consent, that in the course of obtaining necessary regulatory and third party approvals and consents for the merger, no modification, delay, limitation, restriction or condition will be imposed that will have a material adverse effect on FEI or Veeco or the contemplated benefits of the merger and that the merger will be consummated in accordance with the terms of the merger agreement, without waiver, modification or amendment of any material term, condition or agreement contained in the merger agreement. Credit Suisse First Boston was not requested to make, and did not make, an independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of FEI or Veeco, nor was Credit Suisse First Boston furnished with any such evaluations or appraisals. The Credit Suisse First Boston opinion is necessarily based upon information made available to it as of the date of its opinion, and upon financial, economic, market and other conditions as they existed and could be evaluated on the date of the Credit Suisse First Boston opinion. Credit Suisse First Boston did not express any opinion as to what the value of Veeco common stock actually will be when issued to holders of FEI common stock pursuant to the merger or the prices at which shares of Veeco common stock will trade at any time. The Credit Suisse First Boston opinion does not address the relative merits of the merger as compared to other business strategies that might be available to FEI, nor does it address the underlying business decision of FEI to proceed with the merger. Credit Suisse First Boston was not requested to, and did not, solicit third party indications of interest in acquiring all or any part of FEI.

        In preparing its opinion, Credit Suisse First Boston performed a variety of financial and comparative analyses. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Credit Suisse First Boston believes that its analyses must be considered as a whole and that selecting portions of its analyses and of the factors considered by it, without considering all analyses and factors, could create a misleading view of the processes underlying the Credit Suisse First Boston opinion. No company or transaction used in the analyses performed by Credit Suisse First Boston as a comparison is identical to FEI, Veeco or the contemplated merger. In addition, Credit Suisse First Boston may have given various analyses more or less weight than other analyses, and may have deemed various assumptions more or less probable than other assumptions, so that the range of valuation resulting from any particular analysis described below should not be taken to be Credit Suisse First Boston's view of the actual value of FEI or Veeco. The analyses performed by Credit Suisse First Boston are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than suggested by such analyses. In addition, analyses relating to the value of businesses or assets do not purport to be appraisals or to necessarily reflect the prices at which businesses or assets may actually be sold. The analyses performed were prepared solely as part of Credit Suisse First Boston's analysis of the fairness, from a financial point of view, of the merger exchange ratio to holders of FEI common stock, other than PBE and its affiliates, and were provided to the FEI board of directors in connection with the delivery of the Credit Suisse First Boston opinion.

        The following is a summary of material financial analyses performed by Credit Suisse First Boston in connection with the preparation of its opinion and reviewed with the FEI board of directors at a meeting of the FEI board of directors held on July 10, 2002. Certain of the following summaries of financial analyses that were performed by Credit Suisse First Boston include information presented in tabular format. In order to understand fully the material financial analyses that were performed by Credit Suisse First Boston, the tables should be read together with the text of each summary. The tables alone do not constitute a complete description of the material financial analyses.

        Credit Suisse First Boston calculated several values implied by the merger exchange ratio (based on Veeco's closing share price on July 8, 2002), including the implied price per FEI share, the implied premium to FEI's closing share price on July 8, 2002, the implied pro forma fully-diluted ownership of FEI shareholders in the combined company (assuming the conversion of outstanding convertible debt of FEI and Veeco) after the merger and the implied FEI fully-diluted equity value and aggregate value of FEI. The implied fully-diluted equity value was based on the most recently available number of shares of FEI common stock and employee options to purchase shares of FEI common stock outstanding. The implied fully-diluted aggregate value was calculated using the fully-diluted equity value, plus debt, less cash and cash equivalents. The following table summarizes the results of this analysis:

$32.05   44.1%   59.3%   $ 1,089.1 million   $ 1,007.1 million

        Credit Suisse First Boston also calculated the implied fully-diluted aggregate value of FEI and Veeco as a multiple of estimated revenues for calendar years 2002 and 2003 and the implied price per share as a multiple of estimated earnings per share for calendar years 2002 and 2003. These implied values were based on closing share prices for FEI and Veeco on July 8, 2002. These multiples were calculated using the average of publicly available forecasts prepared by securities research analysts. The multiples represent the implied value of the merger relative to FEI's and Veeco's stand-alone trading valuation. The following table summarizes the results of this analysis:

        No company utilized as a comparison in the Comparable Company Trading Analysis is identical to FEI or Veeco. Mathematical analysis, such as determining the mean or the median, is not in itself a meaningful method of using comparable market trading data.

        Credit Suisse First Boston calculated the ratio of FEI's closing share price to Veeco's closing share price for each trading day over various periods ended July 8, 2002, and derived from such values the average of such ratios for each such period (the average market exchange ratio). Credit Suisse First Boston then compared the average market exchange ratio over such periods with the ratio of FEI's closing share price to Veeco's closing share price on July 8, 2002 (the market exchange ratio) and the merger exchange ratio to determine the premium/(discount) of the market exchange ratio and the merger exchange ratio to the average market exchange ratio for each period. This analysis provides an historical perspective of the exchange ratio premium to be received by FEI shareholders in the merger relative to premiums/discounts between FEI's share price and Veeco's share price in the past.

        Credit Suisse First Boston analyzed the relative contributions of FEI and Veeco to the pro forma revenue, operating income, net income and earnings per share of the combined company for calendar years 2000 through 2003. Estimates for calendar years 2002 and 2003 were based on the average of publicly available forecasts prepared by securities research analysts. For each value, Credit Suisse First Boston derived an implied pro forma fully-diluted ownership of FEI shareholders in the combined company based on FEI's relative contribution to the combined company. Credit Suisse First Boston used these implied values to calculate implied exchange ratios and the premium/(discount) to FEI's closing share price on July 8, 2002 implied by such implied exchange ratios. This analysis provides, in the form of an implied exchange ratio, a measure of FEI's relative contribution to various estimated financial metrics of the combined company.

For each group of transactions, Credit Suisse First Boston calculated the premiums/(discounts) implied by the exchange ratio in each transaction relative to the average of the daily ratio of the closing stock price for the target company and the acquiror company in the transaction over various periods prior to public announcement of the transaction. Credit Suisse First Boston then applied the average of such premiums for each group to the average of the daily ratio of the closing price of FEI common stock and Veeco common stock over the same periods to calculate the implied exchange ratios.

No transaction utilized as a comparison in the precedent exchange ratio premiums analysis is identical to the merger. Mathematical analysis, such as determining the average or the median, is not in itself a meaningful method of using comparable transaction data.

        Using a discounted cash flow analysis of both FEI and Veeco on a stand-alone basis, Credit Suisse First Boston calculated various implied exchange ratios based on the values implied by the financial forecasts for calendar years 2002 through 2008 for FEI and Veeco. The forecasts for calendar years 2002 and 2003 were based on the average of publicly available forecasts prepared by securities research analysts. The forecasts for calendar years 2004 through 2008 were based on forecasts approved by the managements of FEI and Veeco, respectively. Such forecasts included various operating assumptions, such as assumptions relating to revenue growth rates, operating income margins, working capital, capital expenditures and depreciation. Credit Suisse First Boston arrived at the operating assumptions applied in the discounted cash flow analysis through analysis of historical operating results, publicly available forecasted operating assumptions and discussions with the managements of Veeco and FEI. Credit Suisse First Boston's analysis used discount rates ranging from 15% to 17% and terminal multiples of unlevered net income of 20.0x to 30.0x. This analysis provides estimated values for FEI and Veeco based on estimated future cash flows and compares, in the form of an implied exchange ratio, the relative implied values of FEI and Veeco resulting from this analysis. The following tables summarize the results of this analysis:

        The actual results achieved by the combined company after the merger may vary from such estimated results and the variations may be material.

        Credit Suisse First Boston's opinion and presentation to the FEI board of directors was one of many factors taken into consideration by the FEI board of directors in making its determination to engage in the merger. Consequently, the analyses described above should not be viewed as determinative of the opinion of the FEI board of directors or the management of FEI with respect to the value of FEI or whether the FEI board of directors would have been willing to agree to a different exchange ratio.

        The FEI board of directors retained Credit Suisse First Boston to act as its financial advisor in connection with the merger. Credit Suisse First Boston was selected by the FEI board of directors based on Credit Suisse First Boston's qualifications, expertise and reputation. Credit Suisse First Boston is an internationally recognized investment banking and advisory firm. Credit Suisse First Boston, as part of its investment banking business, is continuously engaged in the valuation of businesses and securities in connection with mergers and acquisitions, leveraged buyouts, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. In the past, Credit Suisse First Boston and its affiliates have provided advice and services to FEI on various issues relating to equity capital markets for which they have received compensation of approximately $12,450,000. In addition, Credit Suisse First Boston may, in the future, provide investment banking and financial services to Veeco for which it would expect to receive compensation. In the ordinary course of its business, Credit Suisse First Boston and its affiliates may actively trade the debt and equity securities of FEI and Veeco for their own accounts and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.

        Pursuant to an engagement letter dated as of January 25, 2002, as amended, FEI engaged Credit Suisse First Boston to provide financial advisory services to the FEI board of directors in connection with the merger, including, among other things, rendering its opinion. Pursuant to the terms of the engagement letter, FEI has agreed to pay Credit Suisse First Boston a transaction fee equal to approximately $8 million payable upon the consummation of the merger. FEI also has agreed to pay Credit Suisse First Boston a fee of $1,625,000, which became payable upon delivery by Credit Suisse First Boston of its opinion, which amount will be credited against the transaction fee payable to Credit Suisse First Boston. In addition, FEI has agreed to reimburse Credit Suisse First Boston for its out-of-pocket expenses, including attorney's fees, incurred in connection with its engagement and to indemnify Credit Suisse First Boston and certain related persons against certain liabilities and expenses arising out of or in conjunction with its rendering of services under its engagement, including liabilities arising under the federal securities laws.

Structure of the Merger

        Venice Acquisition Corp., a newly formed and wholly-owned subsidiary of Veeco, will be merged with and into FEI. As a result of the merger, the separate corporate existence of Venice Acquisition Corp., will cease and FEI will survive the merger as a wholly-owned subsidiary of Veeco.

        The affirmative vote of a majority of the members of the board of directors of Veeco FEI will be required to modify the powers and authority of any committee of the Veeco FEI board of directors. In addition, the Veeco FEI board of directors may remove a director from a committee, change the size of any committee, terminate any committee or change the chair of a committee only with the affirmative vote of a majority of the members of the Veeco FEI board of directors.

        Compensation of Directors.    In accordance with existing practice of Veeco, it is expected that directors of Veeco FEI who are also full-time employees of Veeco FEI will receive no additional compensation for their services as directors. Each non-employee director will be entitled to receive a fee of $2,000 for each board meeting held in person, $1,000 for each board meeting held by conference call and $1,000 for each committee meeting and will be reimbursed for reasonable expenses incurred in connection with attending meetings. Pursuant to Veeco FEI's 2000 Stock Option Plan, each non-employee director who meets the eligibility criteria for such plan will receive an annual grant of options to purchase 7,000 shares of Veeco FEI common stock with an exercise price equal to the fair market value of a share of Veeco FEI common stock on the date of grant.

Interests of Executive Officers and Directors in the Merger

        General.    Certain directors and officers of FEI and Veeco may have interests in the merger that are different from, or in addition to, the interests of FEI shareholders and Veeco stockholders. Such additional interests are described below to the extent material.

        Veeco FEI Board of Directors.    In accordance with the terms of the merger agreement, the Veeco FEI board of directors will be comprised of 13 members, seven of whom will be nominated by Veeco from Veeco's current board of directors, five of whom will be nominated by FEI from FEI's current board of directors and one of whom will be nominated by PBE.

        Vahé A. Sarkissian,            ,            ,             and            from FEI's board of directors have been nominated by FEI and            has been nominated by PBE to join the Veeco FEI board of directors. Edward H. Braun,            ,            ,             ,            ,             and            from Veeco's board of directors will continue as directors of Veeco FEI.

        FEI Severance Agreements; Severance Payments.    Several FEI officers, including Vahé A. Sarkissian, who is also a director, have severance agreements with FEI. These officers are, or may become, entitled to specific benefits under these agreements as a result of the merger. FEI has entered into severance agreements with each of the following FEI officers:

Officers
   Position
Vahé A. Sarkissian   Chairman, President and Chief Executive Officer
John A. Doherty   Senior Vice President, Worldwide Sales
Jim D. Higgs   Senior Vice President, Human Resources
Bradley J. Thies   Vice President, General Counsel and Secretary
John M. Lindquist   Senior Vice President of Corporate Marketing
Stephen F. Loughlin   Vice President of Corporate Finance, acting Chief Financial Officer and Controller
Steven Berger   Senior Vice President and Chief Technical Officer
Michel Epsztein   Senior Vice President and General Manager, Microelectronics Product Group

70

        Under his current severance agreement with FEI, Mr. Sarkissian would have been entitled to significant severance payments and other benefits upon the closing of the merger. Mr. Sarkissian has entered into an employment agreement with Veeco that will supersede his current severance agreement and he will not, therefore be entitled to or receive any severance payments or other benefits under his current severance agreement. Mr. Sarkissian's new employment agreement is described below in the section titled "Employment Agreements."

        FEI has also entered into severance agreements with the seven other FEI officers listed above. Under the terms of these agreements, each officer is entitled to severance pay in the event his employment is terminated within 18 months following a "change in control" of FEI other than a termination by FEI for cause, death or disability or by the officer without "good reason." Upon such a termination, the executive officer is entitled to a severance payment equal to two times his annual salary plus an amount equal to his target annual bonus for the year in which he is terminated, certain insurance benefits and accelerated vesting of his stock options. The merger of Veeco and FEI is expected to constitute a change of control under these agreements.

        If the employment of any of FEI's officers is terminated following the merger under circumstances entitling them to benefits under their FEI severance agreements, the approximate total amount of lump-sum severance payments that would be owed to each such terminated executive officer would be as follows: John A. Doherty, $480,000, Jim D. Higgs, $368,000, Bradley J. Thies, $333,500, John M. Lindquist, $492,000, Stephen F. Loughlin, $460,000, Steven Berger, $414,000, and Michael Epsztein, $480,000.

        Employment Agreements.    Pursuant to the terms of the merger agreement, Veeco has entered into employment agreements, to be effective upon the closing of the merger, with Vahé A. Sarkissian, FEI's current Chairman, Chief Executive Officer and President, and Edward H. Braun, Veeco's current Chairman, Chief Executive Officer and President. Mr. Sarkissian's employment agreement provides that he will be the Chairman and Chief Strategy Officer of Veeco FEI. Mr. Sarkissian's employment agreement will, when it becomes effective, supersede his severance agreement with FEI, and he will not be entitled to any severance payments or other benefits under his current severance agreement with FEI. Mr. Braun's employment agreement provides that he will be the President and Chief Executive Officer of Veeco FEI. Mr. Braun's employment agreement will supersede his current employment agreement with Veeco. The material terms of Messrs. Sarkissian's and Braun's employment agreements are substantially the same. The table below provides a summary of these employment agreements.

Annual Base Salary   $600,000
Bonus   Up to 100% of annual base salary if performance standards set by board of directors are met
Benefits and Perquisites   Car allowance, benefits and perquisites available to Veeco FEI executives generally and stock options under Veeco FEI stock option plans
Severance   If terminated by Veeco FEI for any reason other than for cause, or if resigns for good reason:
    •   Severance payment equal to three times annual base salary;
    •   100% of target bonus for year in which termination or resignation occurs; and
    •   Accelerated vesting of options, and three years to exercise options.
    If terminated by Veeco FEI for cause or resigns without good reason:
    •   Vesting of options terminates immediately;
    •   All compensation payments terminate immediately; and

71

    •   Severance benefits in accordance with Veeco FEI's established policies as then in effect, if any.
    If terminated for any reason, or resigns for any reason for five years:
    •   Participation in all group health and insurance programs, and all other benefits, fringe benefits and perquisites available generally to senior executives of Veeco FEI.

Under these agreements, termination for cause means:

Under these agreements, resignation for good reason means:

        If the severance and other benefits provided for by the employment agreements or otherwise payable to an executive constitute "parachute payments" within the meaning of Section 280G of the Internal Revenue Code and will be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code, then the executive will receive:

        If the excise tax incurred by the executive is determined by the IRS to be greater or less than the amount determined by the accounting firm the parties employed, then Veeco FEI and the executive agree to make such additional payment, including interest and any tax penalties, to the other party as the accountants reasonably determine is appropriate to ensure that the net economic effect to the executive, on an after-tax basis, is as if the Internal Revenue Code Section 4999 excise tax did not apply to him.

72


        Each executive has agreed that, during the employment term and for two years after termination of his employment with Veeco FEI, he will not, in the United States or anywhere else in the world where Veeco FEI conducts business:

For purposes of these non-compete provisions, the phrase, "competing business purpose" means the designing, manufacturing, marketing and servicing of products that deposit or etch materials on a substrate or that provide critical measurements of certain features utilized in data storage and semiconductor devices.

        In addition, each executive has agreed that he will not, directly or indirectly, solicit, encourage or take any other action that is intended to induce or encourage, or has the effect of inducing or encouraging:

        Under Mr. Sarkissian's employment agreement, Veeco acknowledged that FEI and Mr. Sarkissian had amended Mr. Sarkissian's Non-Negotiable Promissory Note dated June 25, 1998 (in the principal amount of $1,115,530) to provide for (1) an extension of the due date of all amounts owed pursuant to such note from June 24, 2002 to June 24, 2005 and (2) an increase in the interest rate payable under such note from 5.58% per annum to 5.75% per annum. This amendment was made as of June 23, 2002.

        FEI Option Plans.    Under the merger agreement, all stock options to purchase shares of FEI common stock held by FEI officers and directors on the date of the merger will be converted into similar options to purchase Veeco FEI common stock.

        Indemnification; Directors and Officers Insurance.    From and after the closing of the merger, Veeco will, and will cause FEI, as a wholly-owned subsidiary of Veeco, to, fulfill and honor in all respects the obligations of FEI pursuant to any indemnification agreements between FEI and its directors and officers in effect immediately prior to the closing of the merger, subject to applicable law. The articles of incorporation and bylaws of FEI following the closing of the merger will contain provisions with respect to exculpation and indemnification that are at least as favorable to these indemnified persons as those provisions contained in the articles of incorporation and bylaws of FEI as in effect on the date of the merger agreement, which provisions will not be amended, repealed or otherwise modified for a period of six years from the closing of the merger in any manner that would adversely affect the rights of the indemnified persons thereunder, unless such modification is required by law. Also, for six years after the closing of the merger, FEI will, and Veeco will cause FEI to, maintain FEI's directors' and officers' liability insurance policy in respect of acts or omissions occurring prior to the completion of the merger, covering each person covered by FEI's officers' and directors' liability insurance policy in effect on July 11, 2002. FEI may substitute its own directors' and officers' policy of comparable coverage, but will not be obligated to pay annual premiums in excess of 200% of the premium payable by FEI therefor as of July 11, 2002. If FEI cannot obtain such comparable coverage for such 200%

73


amount, FEI shall be entitled to reduce the amount of coverage to an amount that can be obtained for a premium equal to such 200% amount.

        PBE.    William E. Curran and Jan C. Lobbezoo, representatives of PBE, currently serve on the FEI board of directors.                 has been nominated by PBE to serve on the Veeco FEI board of directors in accordance with the terms of an investor agreement among Veeco, FEI and PBE. PBE also has entered into certain agreements with FEI and Veeco that will remain in effect after the merger, and PBE and Philips may enter into additional agreements with Veeco FEI after the merger. For additional information regarding certain of these agreements and other arrangements among FEI and Philips and PBE, see the section titled "Other Agreements" beginning on page 96 and the other public filings of FEI incorporated by reference herein. Also, see the section titled "Where You Can Find More Information" beginning on page 134.

Issuance of Shares in Connection with the Merger

        The rules of The Nasdaq National Market, on which Veeco's common stock is listed, require stockholder approval for the issuance of shares of common stock in any transaction where the number of shares to be issued will be equal to 20% or more of the number of shares of common stock outstanding before the issuance. Veeco expects to issue approximately 44,000,000 shares of its common stock in the merger to FEI shareholders (and up to approximately 10,000,000 shares which may be issued in respect of FEI's options and other rights and convertible notes), representing approximately 185% of its shares of common stock outstanding before the issuance of its shares in the merger. Thus, Veeco is seeking stockholder approval of the issuance of the Veeco common stock in the merger  (including shares that may be issued in respect of FEI's options and other rights and convertible notes).

Resale of Veeco Common Stock Issued in the Merger

        The shares of Veeco FEI common stock to be issued in connection with the merger will be registered under the Securities Act, and will be freely transferable, except for shares of Veeco FEI common stock issued to any person deemed to be an "affiliate" of Veeco FEI for purposes of Rule 144 under the Securities Act, and to any person deemed to be an affiliate of FEI for purposes of Rule 145 under the Securities Act at the time the merger is submitted to a vote of the Veeco stockholders or the FEI shareholders, as applicable. Persons who may be deemed to be affiliates include individuals or entities that control, are controlled by, or are under common control with either Veeco or FEI, and may include some officers, directors and principal stockholders of Veeco and FEI. Affiliates of FEI prior to the merger may not sell shares of Veeco FEI common stock acquired in connection with the merger except pursuant to an effective registration statement under the Securities Act covering such shares, or in compliance with Rule 145 under the Securities Act or another applicable exemption from the registration requirements of the Securities Act. Affiliates of Veeco FEI after the merger may not sell shares of Veeco FEI common stock acquired in connection with the merger except pursuant to an effective registration statement under the Securities Act covering such shares, or in compliance with Rule 144 under the Securities Act or another applicable exemption from the registration requirements of the Securities Act.

        Veeco's registration statement of which this joint proxy statement/prospectus forms a part does not cover the resale of Veeco FEI common stock to be received by FEI affiliates in the merger.

Listing of Veeco Common Stock Issued in the Merger

        It is a condition to the closing of the merger that the shares of Veeco common stock to be issued in the merger be approved for listing on The Nasdaq National Market, subject to notice of issuance.

74

Delisting and Deregistration of FEI Common Stock; Cessation of Periodic Reporting

        If the merger is consummated, the FEI common stock will cease to be listed on The Nasdaq National Market. In such event, FEI intends to apply to the SEC for the deregistration of such securities. Upon such deregistration, FEI will no longer be required to make separate periodic filings with the SEC under the Exchange Act.

Material U.S. Federal Income Tax Consequences of the Merger

        Wilson Sonsini Goodrich & Rosati, Professional Corporation, and Kaye Scholer LLP, have provided opinions to FEI and Veeco, respectively, dated as of the effective date of the registration statement of which this joint proxy statement/prospectus forms a part, to the effect that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code. These tax opinions have been filed with the SEC as exhibits 8.1 and 8.2 to the registration statement on Form S-4 of which this joint proxy statement/prospectus forms a part. The tax opinions rely on certain customary assumptions, including assumptions regarding the absence of changes in existing facts and the completion of the merger in accordance with this joint proxy statement/prospectus and the merger agreement. The tax opinions also rely on certain factual representations contained in officer's certificates of Veeco and FEI. These assumptions and representations must be true and accurate as of the effective date of the registration statement, and must continue to be true and accurate as of the closing of the merger, or the conclusions contained in the tax opinions and this tax discussion could be affected.

        The tax opinions and this tax discussion assume that FEI shareholders hold their shares of FEI common stock as capital assets. Further, the tax opinions and this tax discussion do not address all of the U.S. federal income tax consequences that may be relevant to FEI shareholders in light of their particular circumstances; nor do the tax opinions or this tax discussion address the federal income tax consequences that may be applicable to taxpayers subject to special treatment under the Internal Revenue Code, such as:

        No information is provided in this document with respect to the tax consequences, if any, of the merger under applicable foreign, state, local and other tax laws. The tax opinions and this tax discussion are based upon the provisions of the Internal Revenue Code, applicable Treasury regulations, Internal Revenue Service rulings and judicial decisions, as in effect as of the date of this document. There can be no assurance that future legislative, administrative or judicial changes or interpretations, which changes or interpretations could apply retroactively, will not affect the accuracy of the statements or conclusions set forth in the tax opinions or this tax discussion. No rulings have been or will be sought from the Internal Revenue Service concerning the tax consequences of the merger, and the tax

75

opinions and this tax discussion as to the material U.S. federal income tax consequences of the merger will not be binding on the Internal Revenue Service or any court.

        The tax opinions and this tax discussion do not purport to contain a complete analysis or discussion of all potential tax effects relevant to the merger. Thus, FEI shareholders are urged to consult their own tax advisors as to the specific tax consequences to them of the merger, including tax return reporting requirements, the applicability and effect of federal, state, local, foreign and other applicable tax laws and the effect of any proposed changes in the tax laws.

        As set forth in the tax opinions, Wilson Sonsini Goodrich & Rosati, Professional Corporation, counsel to FEI, and Kaye Scholer LLP, counsel to Veeco, are of the opinion that the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code and that the following material U.S. federal income tax consequences will result from such qualification:

        In the event that Kaye Scholer LLP and Wilson Sonsini Goodrich & Rosati, Professional Corporation, are unable to deliver closing tax opinions substantially in the form of Exhibits 8.1 and 8.2, respectively, then it may be necessary to resolicit the votes of Veeco stockholders and FEI shareholders and provide them with updated disclosure regarding the federal income tax consequences of the merger.

        Other Tax Matters.    It is a condition to the obligations of FEI and Veeco to consummate the merger that Wilson Sonsini Goodrich & Rosati, Professional Corporation, counsel to FEI, and Kaye Scholer LLP, counsel to Veeco, each renders an opinion to its respective client, dated as of the closing date of the merger, to the effect that the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code. These opinions will be based on updated representations contained in officer's certificates to be provided by FEI and Veeco as of the closing date of the merger, and on customary factual representations.

Accounting Treatment of the Merger

        The merger will be accounted for using the purchase method for financial reporting and accounting purposes. After the merger, the results of operations of FEI will be included in the consolidated financial statements of Veeco.

Regulatory Filings and Approvals Required to Complete the Merger

        The merger is subject to the requirements of the HSR Act, which prevents some transactions from being completed until required information and materials are furnished to the Antitrust Division of the Department of Justice and the Federal Trade Commission and the appropriate waiting periods are terminated or expire. Veeco, FEI and Philips have filed the required information and materials with the Antitrust Division of the Department of Justice and the Federal Trade Commission. The requirements of the HSR Act will be satisfied if the merger is completed within one year after the termination or expiration of this waiting period. Additionally, the transaction is subject to notification to the Federal Cartel Office pursuant to the competition laws of Germany.

        If, prior to the expiration of the waiting period, the FTC or the Antitrust Division should request additional information or documentary material under the HSR Act, completion of the merger could be delayed until after the companies have substantially complied with the request. On August 12, 2002, the Antitrust Division of the Department of Justice contacted Veeco and FEI and advised them that it intends to conduct a preliminary inquiry into the transaction. On September 18, 2002, Veeco and FEI received a request from the Antitrust Division of the Department of Justice for additional information under the HSR Act regarding the merger. This second request has the effect of extending the waiting period under the HSR Act until 30 days after Veeco and FEI comply with the request. Veeco and FEI intend to promptly respond to the request. The companies currently cannot estimate how long it will take to comply with this request. There can be no assurances that regulators will terminate the waiting period under the HSR Act or allow the waiting period to expire or will not take action or prohibit the merger or condition the merger on restrictions that would negatively impact the combined company. At any time before or after the closing of the merger, the Federal Trade Commission, the Antitrust Division of the Department of Justice or any state or foreign competition authority could take any action under applicable antitrust or competition laws as it deems necessary or desirable, including challenging the merger. Other persons could take action under applicable antitrust laws, including seeking to enjoin the merger. Additionally, at any time before or after the completion of the merger, even if the applicable waiting period under the HSR Act expired or was terminated, any state could take action under applicable antitrust laws. A challenge could be made to the merger and, if such a challenge is made, FEI and Veeco might not prevail.

        Both Veeco and FEI conduct business in a multitude of foreign nations. The laws of these nations may require Veeco and/or FEI to make certain filings with certain regulatory bodies in these countries. In Germany, Veeco and FEI made pre-merger notification filings with the German Federal Cartel Office. On September 19, 2002, Veeco and FEI were notified by the German Federal Cartel Office that the proposed merger will not be investigated as it does not meet the prerequisites for a prohibition pursuant to Sec. 36(1) of the Act Against Restraints of Competition. Veeco FEI also is required to make a post-closing notification filing in Japan in connection with the merger.

        Neither Veeco nor FEI is aware of any other material governmental or regulatory approval required for closing the merger, other than the effectiveness of the registration statement of which this joint proxy statement/prospectus forms a part and compliance with the Delaware General Corporation Law and the Oregon Business Corporation Act. See the section titled "The Merger Agreement—Certain Covenants—Antitrust Matters" on page 84.

Closing and Effectiveness of the Merger

        Unless otherwise agreed by Veeco and FEI, the merger will be completed no later than the second business day following the date on which all of the conditions to closing of the merger are satisfied or waived, including the approval of the merger by the FEI shareholders and the approval of the issuance of Veeco common stock in connection with the merger and the amendment to Veeco's Amended and Restated Certificate of Incorporation to increase the authorized shares of Veeco's common stock by the Veeco stockholders. The merger will become effective upon the filing of articles of merger with the Secretary of State of Oregon.

THE MERGER AGREEMENT

        The following is a brief summary of certain material provisions of the merger agreement. This summary does not purport to be complete and is qualified in its entirety by reference to the merger agreement. The merger agreement is attached as Appendix A to this joint proxy statement/prospectus. We urge you to carefully review the merger agreement.

Structure of the Merger

        The merger agreement provides that Venice Acquisition Corp. will be merged with and into FEI, the separate existence of Venice Acquisition Corp. will cease and FEI will continue as the surviving corporation and a direct wholly-owned subsidiary of Veeco. As a result of the merger, the surviving corporation will possess all the property, rights and franchises of FEI and Venice Acquisition Corp., and will be subject to all the debts, restrictions and duties of FEI and Venice Acquisition Corp.

Closing of the Merger

        The closing of the merger will take place no later than the second business day after satisfaction or waiver of the conditions to the merger (unless another time is agreed to by the parties). At such time, Veeco and FEI will file articles of merger with the Secretary of State of Oregon and make all other filings or recordings required by the Oregon Business Corporation Act in connection with the merger. The merger will become effective upon such filing with the Secretary of State of Oregon or at such later time as is specified in the articles of merger. If the FEI shareholders and the Veeco stockholders approve the merger, the closing of the merger is expected to occur as soon as practicable following the FEI special meeting and the Veeco special meeting.

Merger Consideration

        General.    As of the closing of the merger, each outstanding share of FEI common stock will be converted into the right to receive 1.355 shares of Veeco common stock. Veeco will not issue fractional shares of Veeco common stock in exchange for shares of FEI common stock in the merger. Veeco will pay a holder of shares of FEI common stock an appropriate amount of cash in lieu of any fractional shares otherwise issuable. Such cash amount will be based upon the closing price per share of Veeco common stock on the trading day immediately preceding the closing of the merger.

        No Appraisal/Dissenters' Rights.    In connection with the merger, neither Veeco stockholders nor FEI shareholders are entitled to dissent from the merger or request an appraisal of the value of their shares under the Delaware General Corporation Law or the Oregon Business Corporation Act.

        Exchange of Certificates.    On or prior to the closing date of the merger, Veeco will select a reputable bank or trust company to act as exchange agent in the merger. Promptly, but no more than three days after the closing of the merger, Veeco will deposit with the exchange agent certificates representing the shares of Veeco common stock issuable in the merger and cash sufficient to make payments in lieu of fractional shares in the merger.

        As soon as is reasonably practicable after the closing of the merger, the exchange agent will mail to each record holder of a certificate which, before the merger, represented shares of FEI common stock:

        Upon surrender of such certificate(s) to the exchange agent, together with a properly completed letter of transmittal covering such shares and other customary documentation, the holder of such

78


certificate(s) will be entitled to receive in exchange therefor a certificate representing the number of whole shares of Veeco common stock that such holder has the right to receive and cash in lieu of any fractional share. The stock certificate previously representing shares of FEI common stock shall be canceled. As of the closing of the merger, all shares of FEI common stock will no longer be outstanding and will automatically be canceled and retired and will cease to exist. Each holder of a certificate previously representing any such shares of FEI common stock will cease to have any rights with respect to those shares, other than the right to receive the shares of Veeco common stock (and cash in lieu of fractional shares) upon surrender of the certificate(s) representing such shares of FEI common stock, as contemplated by the merger agreement. FEI shareholders should not forward their FEI stock certificates to the exchange agent without a letter of transmittal. FEI shareholders should NOT return their stock certificates with the enclosed proxy.

        FEI Options.    As of the closing of the merger, each outstanding option to purchase shares of FEI common stock will be assumed by Veeco and converted, in accordance with its terms, into an option to purchase the number of shares of Veeco FEI common stock equal to 1.355 multiplied by the number of shares of FEI common stock which could have been obtained immediately prior to the merger upon the exercise of such option, rounded to the nearest whole share. Following the closing of the merger, the exercise price under any such option will be equal to the exercise price per share of FEI common stock thereunder immediately prior to the closing of the merger, divided by 1.355, rounded to the nearest whole cent. In general, the other terms and conditions of each FEI option will continue to apply in accordance with the terms of the stock option plan or other arrangement under which the option was issued. Not later than the date on which the merger becomes effective, Veeco will file a registration statement on Form S-8 with the SEC relating to the shares of Veeco common stock issuable upon the exercise of FEI options assumed by Veeco in the merger.

        FEI Convertible Debt.    The FEI notes shall become convertible solely into such number of shares of Veeco FEI common stock that would have been issued if the FEI notes had been converted into FEI common stock immediately prior to the closing of the merger. The FEI notes shall continue to be governed by and subject to the Indenture, dated as of August 3, 2001, between FEI and BNY Western Trust Company under which the FEI notes were originally issued, but shall be convertible solely into shares of Veeco FEI common stock as described above. On a date no later than the date on which the merger becomes effective, Veeco will file a registration statement on Form S-3 relating to the resale of the FEI notes and the Veeco common stock issuable upon conversion of the FEI notes.

Representations and Warranties

        The merger agreement contains generally reciprocal representations and warranties made by each of Veeco and Venice Acquisition Corp., on the one hand, and FEI, on the other, regarding aspects of their respective businesses, financial condition and structure, as well as other facts pertinent to the merger. These representations and warranties relate to the following subject matters with respect to each party:

        With the exception of PBE, FEI shareholders have also agreed not to transfer their shares of FEI common stock prior to the earlier of (1) the closing of the merger or (2) the termination of the merger agreement. PBE has agreed not to transfer its shares except (1) to a transferee that agrees to be bound by the voting agreement between PBE and Veeco and that enters into standstill arrangements identical in substance to those contained in the investor agreement among Veeco, FEI and PBE, or (2) in an FEI Acquisition Transaction, to a transferee that has made a Superior FEI Proposal.

        The voting agreements and the irrevocable proxies terminate upon the earliest to occur of:

        Other than inducing Veeco to enter into the merger agreement, none of these FEI shareholders (other than PBE) received any additional consideration in exchange for entering into the voting agreement and granting the irrevocable proxy. As additional consideration for PBE entering into the voting agreement, Veeco also entered into an investor agreement with PBE and FEI, which agreement is more fully described below.

Investor Agreement With PBE

        The following is a summary of material provisions of an investor agreement entered into among Veeco, FEI and PBE. A copy of such investor agreement is attached as Appendix G to this joint proxy statement/prospectus. This summary does not purport to be complete, and is qualified in its entirety by reference to such document. We urge you to carefully review such investor agreement.

        At the time of the execution of the merger agreement, PBE, FEI's largest shareholder, entered into an investor agreement with Veeco and FEI.

Registration Rights

        Under the terms of the investor agreement, Veeco agreed to grant to PBE certain demand registration and "piggyback" registration rights with respect to the shares of Veeco FEI common stock to be acquired by PBE in connection with the merger.

        Specifically, Veeco has agreed that at any time following the closing of the merger, to and including the date on which the shares of Veeco FEI common stock owned by PBE may be publicly offered for sale in the United States by PBE without restriction and without registration under the

97


Securities Act, PBE shall have the right on two occasions to require Veeco FEI to file a registration statement under the Securities Act in respect of at least one-third of the Veeco FEI common stock held by PBE and its affiliates at the time of the closing of the merger.

        In addition, if, at any time following the closing of the merger, Veeco FEI proposes, subject to certain exceptions, to register any shares of Veeco FEI common stock under the Securities Act, Veeco FEI shall give prompt written notice to PBE of its intention to do so, and, upon the written direction of PBE, Veeco FEI shall include in such registration statement such number of shares of Veeco FEI common stock owned by PBE and its affiliates as PBE may request, subject to customary provisions regarding "cutbacks."

Representation on Veeco FEI Board of Directors

        Under the investor agreement, Veeco also has agreed that from the closing of the merger until the earlier of:

PBE may request that Veeco FEI include, as a nominee or designee to Class II (with a term expiring in 2005) of Veeco FEI's board of directors, one person nominated by PBE and reasonably satisfactory to Veeco FEI's board of directors. In the event of the death, incapacity, resignation or removal from Veeco FEI's board of directors of any PBE stockholder nominee, Veeco FEI shall cause another PBE stockholder nominee to be elected or appointed as a director to fill the vacancy.

Purchase of Additional Shares of Veeco FEI Common Stock

        PBE and FEI also have agreed to terminate, as of the closing of the merger, Sections 2.1 and 5.18 of the Combination Agreement, dated November 15, 1996, between FEI and PBE and Section 4 of the Agreement, effective as of December 31, 2000, among FEI, PBE and Philips, which relate to the right of PBE to purchase additional shares of FEI common stock upon the exercise of FEI stock options. In return, Veeco assumed FEI's obligation to issue up to 401,007 additional Veeco shares of common stock to PBE upon the exercise of certain outstanding options. This includes the obligation to, at the sole option of PBE, transfer to PBE, no later than 30 calendar days following the close of the calendar quarter in which the closing of the merger occurs:

Veeco FEI has also assumed FEI's obligation to, at the sole option of PBE, transfer to PBE, no later than 30 calendar days following the close of each calendar quarter following the calendar quarter of Veeco FEI in which the closing of the merger occurs, a number of securities equal to the product of (1) 122.22%, multiplied by (2) the number of securities issued and stock options "cashed out" during such quarter upon exercise of such stock options.

98


Standstill Provisions

        Under the investor agreement, until the earliest to occur of (1) the termination (prior to the closing of the merger) of the merger agreement, (2) a change in control of Veeco FEI, (3) the first date on which Philips ceases to beneficially own at least 7.5% of the total current voting power of Veeco FEI, and (4) the date of the 2005 annual meeting of stockholders of Veeco FEI, PBE is subject to certain standstill restrictions and has agreed that it shall not, and shall not permit its affiliates to, without the prior written approval of Veeco FEI:

        Other Obligations of PBE.    Other obligations of PBE under the investor agreement include PBE's obligation to promptly notify Veeco FEI upon PBE's or its affiliates' acquisition of additional Veeco FEI common stock and to be present (and to cause all of its affiliates holding Veeco FEI common stock to be present), at Veeco FEI's request, in person or by proxy, at all meetings of stockholders of Veeco FEI so that all such shares of Veeco FEI common stock may be counted for purposes of determining the presence of a quorum at such meetings.

        Veeco Stockholder Rights Plan.    Under the investor agreement, Veeco also agreed that the rights under its Rights Agreement, dated as of March 13, 2001, between Veeco and American Stock Transfer and Trust Company, as previously amended, will not be exercisable as a consequence of the beneficial ownership by Philips or its affiliates of the shares of Veeco common stock issued to PBE pursuant to the merger agreement or upon the future acquisition of shares of Veeco FEI common stock purchased pursuant to the exercise of FEI stock options assumed by Veeco FEI as discussed above.

99


        Termination of Investor Agreement.    The investor agreement will terminate upon the earliest to occur of:

Amendment Agreement among FEI, PBE and Philips

        The following is a summary of material provisions of an amendment agreement entered into among FEI, Philips and PBE. A copy of such amendment agreement is attached as Appendix H to this joint proxy statement/prospectus. This summary does not purport to be complete, and is qualified in its entirety by reference to such document. We urge you to carefully review such amendment agreement.

        At the time of the execution of the merger agreement, PBE, Philips and FEI entered into an agreement pursuant to which they agreed to terminate, at the closing of the merger, Section 5.16(e) of the Combination Agreement, dated November 15, 1996, between FEI and PBE, which subjects FEI's patents and patent applications to certain cross-licensing, pooling and other patent sharing or licensing arrangements with PBE. The termination of Section 5.16(e) does not modify or alter the validity or the scope of any cross-licensing, pooling or other patent sharing or licensing arrangements with PBE entered into prior to July 11, 2002.

        Under the amendment agreement, PBE, Philips and FEI also have agreed to terminate, at the closing of the merger, Sections 1(b)(v) and 5 of the Agreement, effective as of December 31, 2000, among FEI, PBE and Philips, which provide for (1) FEI's opportunity to confidentially review Philips' patent applications in areas related to FEI's business and (2) cash payments to be made by Philips to FEI in 2002 and 2003.


RELATIONSHIP WITH PHILIPS

        On February 21, 1997, FEI acquired substantially all of the assets and liabilities of Philips' electron optics business, in exchange for which PBE received 55% of the then outstanding FEI common stock and an obligation from FEI to issue additional shares of FEI common stock to PBE when FEI stock options outstanding as of February 21, 1997 are exercised. On December 31, 2000, FEI and Philips entered into an agreement to clarify certain relationships and transactions between the parties. This agreement provided that certain benefits that FEI had been receiving as a result of Philips having majority-control of FEI would cease on the first day after PBE's ownership of FEI fell below 45% of FEI's outstanding common stock and other benefits to FEI would cease 120 days after the day on which PBE's ownership of FEI fell below 45% and still other benefits to FEI would cease at subsequent future dates. PBE's ownership of FEI fell below 45% on May 22, 2001, the date on which FEI completed a secondary public offering. As a result, FEI has ceased to receive many of these benefits. In addition, certain ongoing separation payments that Philips agreed to make to FEI in the December 31, 2000 agreement will cease as of the closing of the merger. As a result, assuming the merger closes on December 31, 2002, FEI will not receive $1 million from Philips that FEI likely would have received during 2003 if not for the closing of the merger.

100

FEI's acquisition of Philips' electron optics business in 1997

        On February 21, 1997, FEI acquired substantially all of the assets and liabilities of Philips' electron optics business, in exchange for which PBE received 55% of the then outstanding FEI common stock and an obligation from FEI to deliver to PBE additional shares of FEI common stock when FEI stock options outstanding as of February 21, 1997 are exercised. These additional shares are issuable at a rate of approximately 1.22 shares of FEI common stock for each share of FEI common stock issued upon exercise of the options. Pursuant to this arrangement, 295,946 shares of FEI common stock (equivalent to 401,007 shares of Veeco common stock after giving effect to the exchange ratio) potentially are issuable to PBE.

        As long as PBE maintained majority control of FEI, FEI derived significant benefits from its relationship with Philips. These benefits included:

        Certain subassemblies included in FEI's products are purchased from a Philips subsidiary. We do not expect that the merger will affect FEI's relationship with Philips' subsidiary suppliers. We do not expect that agreements between FEI and Philips' subsidiary suppliers will terminate, or that the terms of those agreements will change, as a result of the merger. The agreements between FEI and Philips' subsidiary suppliers were negotiated, and will continue to be negotiated, at arms length.

Clarification of Philips agreements in 2000

        On December 31, 2000, FEI and Philips entered into an agreement that clarified certain relationships and transactions between the parties and contemplated that at some point in the future PBE would no longer hold majority control of FEI. The agreement provided, among other things, that certain benefits to FEI would cease on the first day after PBE's ownership of FEI fell below 45% of FEI's outstanding common stock and other benefits to FEI would cease 120 days after the day on which PBE's ownership of FEI fell below 45%. Additionally, the agreement required Philips to make certain ongoing separation payments to FEI, up to an aggregate of $6 million, primarily to reduce the effect of increased pension costs on FEI. These payments were made by Philips in an aggregate of $3 million in 2001, payable in equal monthly installments of $250,000, and are to be made by Philips in an aggregate of $2 million in 2002, payable in equal monthly installments of $166,667, and in an aggregate of $1 million in 2003, payable in equal monthly installments of $83,333. These termination payments, however, terminate upon a change of control of FEI.

Changes resulting from FEI's secondary offering in 2001

        On May 22, 2001, FEI completed a public offering of 3,066,666 shares of FEI common stock sold by FEI and 6,133,334 shares of FEI common stock sold by PBE. At the completion of this offering,

101



PBE's ownership of FEI common stock was reduced to 8,111,211 shares, or 25.5% of the total shares of FEI common stock then outstanding, from its 49.8% ownership prior to the offering. As a result, PBE's ownership of FEI common stock fell below the 45% threshold and FEI began to lose the rights to the benefits identified in the list above. From and after May 22, 2001, FEI began to incur increased operating costs, which are reflected in FEI's income statement, due to the loss of some of these benefits and has replaced most of the arrangements with Philips by procuring services from other suppliers.

        In 2001, FEI paid Philips approximately $4.5 million for the services described above. Because FEI must now procure these services from third parties, who seek to earn profits in addition to their cost recovery, the cost of replacing these services has and will exceed the amounts previously paid to Philips for them, though FEI is not able to quantify the overall increase in costs because the services that FEI contracted changed from 2001 to 2002. Some of the specific types of increased costs the combined company has incurred or will incur, quantified where possible, include the following:

102

Changes resulting from merger

        FEI expects the payments from Philips under the December 31, 2000 agreement with Philips, which originally were to be up to $6 million, to end upon the closing of the merger. These separation payments were $3 million in 2001 paid monthly, $2 million in 2002 paid monthly and $1 million in 2003 paid monthly. Accordingly, assuming the merger closes as of December 31, 2002, FEI expects to lose the right to $1 million in reimbursement payments from Philips.

        In connection with the merger, Veeco, FEI and PBE entered into an investor agreement, dated as of July 11, 2002. This investor agreement provides for, among other things, the following:

        The investor agreement is attached as Appendix G to this joint proxy statement/prospectus. For a more detailed description of the terms and conditions of the investor agreement, see the section titled "Other Agreements-Investor Agreement with PBE" beginning on page 97.

103


AMENDMENT TO VEECO'S AMENDED AND RESTATED
CERTIFICATE OF INCORPORATION TO INCREASE
THE NUMBER OF AUTHORIZED SHARES OF VEECO COMMON STOCK

        Veeco's Amended and Restated Certificate of Incorporation authorizes the issuance of up to 60,000,000 shares of Veeco common stock. As of June 30, 2002, there were 29,134,679 shares of Veeco common stock issued and outstanding, and the following shares were reserved for issuance:

Shares
   Reserved for Issuance:
6,122,330   Upon exercise of stock options which have been granted pursuant to Veeco's stock option plans or assumed by Veeco in connection with the mergers with CVC and Applied Epi
211,603   Upon exercise of warrants assumed in connection with the Applied Epi merger
878,286   Upon the exercise of stock options available for grant under Veeco's stock option plans
78,155   Upon the sale of stock pursuant to Veeco's employee stock purchase plan
5,712,802   Upon conversion of Veeco's 41/8% subordinated convertible notes due 2008
   
13,003,176   Total Shares Reserved For Issuance
   

        After taking into account the shares issued and outstanding and the shares reserved for issuance as set forth above, but prior to consummation of the merger, Veeco has 17,862,145 shares of common stock available for issuance.

        In connection with the merger, Veeco will be obligated to issue approximately 44,000,000 shares of Veeco common stock and to reserve the following shares for issuance:

Approximate
Shares
   Reserved for Issuance:
4,206,854   Upon exercise of stock options which have been granted pursuant to FEI's stock option plans and assumed by Veeco in connection with the merger
401,007   To PBE under the investor agreement
530,679   Upon the sale of stock pursuant to FEI's employee stock purchase plan
4,788,470   Upon conversion of FEI's 5.5% convertible subordinated notes due 2008
   
9,927,010   Total Shares Reserved For Issuance
   

        At the Veeco special meeting, the Veeco stockholders will be asked to consider and vote upon a proposal, unanimously recommended and determined to be advisable by Veeco's board of directors, to amend Article 4 of Veeco's Amended and Restated Certificate of Incorporation, in order to increase the number of shares of Veeco common stock that Veeco has authority to issue from 60,000,000 shares to 175,000,000 shares. The purpose of the amendment is to provide Veeco with additional shares of Veeco common stock that may be used in connection with the merger and future acquisitions, for stock

104


splits and stock dividends and for other corporate purposes, including the raising of additional capital, at times when the board of directors of Veeco, in its discretion, deems it advantageous to do so.

        Assuming the approval and effectiveness of the proposed amendment to Veeco's Amended and Restated Certificate of Incorporation and the completion of the merger, it is anticipated that Veeco will have approximately 79,000,000 authorized and unissued shares of Veeco common stock after the merger (after taking into account the number of issued and outstanding shares of Veeco common stock, the number of shares reserved for issuance by Veeco upon the exercise of Veeco's stock options and warrants, shares reserved for issuance under Veeco's employee stock purchase plan, shares reserved for issuance upon conversion of Veeco's outstanding convertible debt securities, shares to be issued to FEI shareholders in the merger, shares issuable upon the exercise of FEI options and upon conversion of the FEI notes assumed by Veeco in the merger, shares reserved for issuance under FEI's employee stock purchase plan assumed in the merger and shares that may become issuable to PBE under the investor agreement), which Veeco's board of directors would be able to authorize for issuance for the foregoing purposes, at any time, without obtaining further authorization from the holders of Veeco common stock, unless such authorization is required by applicable law, regulation or the rules of any stock exchange on which shares of Veeco's common stock may then be listed. Except as described above, no specific use of the additional shares of Veeco common stock is presently contemplated, although Veeco has considered additional acquisitions from time to time and reserves the right to use any additional authorized shares in the discretion of Veeco's board of directors. Holders of shares of Veeco common stock have no preemptive rights in connection with the issuance of additional shares of Veeco common stock. A vote in favor of this proposal to amend Veeco's Amended and Restated Certificate of Incorporation will not be deemed to be a vote to approve the issuance of Veeco shares in the merger, the proposed amendment to Veeco's Amended and Restated Certificate of Incorporation relating to the change of the name of Veeco Instruments Inc. to Veeco FEI Inc. or the proposed amendment to Veeco's First Amended and Restated Employee Stock Purchase Plan.

        The issuance of additional shares of Veeco common stock may dilute the present equity ownership position of Veeco stockholders. The issuance of additional shares of Veeco common stock may, among other things, have a dilutive effect on Veeco's earnings per share and on the equity and voting power of existing Veeco stockholders and may adversely affect the market price of the Veeco common stock.

        The availability for issuance of additional shares of Veeco common stock could enable Veeco's board of directors to render more difficult or discourage an attempt to obtain control of Veeco. The additional shares of Veeco common stock also could be utilized to render more difficult a merger or similar transaction, even it if appears to be desirable to a majority of the Veeco stockholders. Veeco is not aware of any pending or threatened efforts to obtain control of Veeco.

        If Veeco's stockholders do not approve the proposed amendment to Veeco's Amended and Restated Certificate of Incorporation, Veeco would not have enough authorized shares to cover the shares to be issued to FEI shareholders in the merger and to be reserved for issuance upon the exercise of FEI stock options and conversion of the FEI notes to be assumed by Veeco in the merger. In that event, Veeco could be deemed to be in violation of contractual provisions in the merger agreement which, if deemed material, could give rise to FEI's right to terminate the merger agreement. In the case of such a termination by FEI, Veeco could be required to pay FEI's fees and expenses incurred in connection with the merger agreement and the merger. In addition, Veeco would not have such additional shares of Veeco common stock available for use in connection with the future acquisitions, for stock splits and stock dividends, and for other corporate purposes, including the raising of additional capital.

        The full text of the proposed amendment to Veeco's Amended and Restated Certificate of Incorporation is set forth in Appendix F-1 hereto and the description of the proposed amendment herein is qualified in its entirety by reference to such Appendix F-1.

105


        The affirmative vote of the holders of a majority of the outstanding shares of Veeco common stock entitled to vote thereon will be required to amend Veeco's Amended and Restated Certificate of Incorporation to increase the number of authorized shares of Veeco common stock.

        The board of directors of Veeco believes that approval of this amendment to Veeco's Amended and Restated Certificate of Incorporation is in the best interests of Veeco and Veeco's stockholders and determined that this amendment is advisable. The board of directors of Veeco unanimously recommends a vote "FOR" approval of the amendment to increase the authorized number of shares of Veeco common stock as described above at Veeco's special meeting. In the event that this proposed amendment and the proposed amendment to change the name of Veeco to Veeco FEI are not approved by Veeco's stockholders at the Veeco special meeting, the Amended and Restated Certificate of Incorporation in effect as of the date hereof will remain in full force and effect.

106


AMENDMENT TO VEECO'S AMENDED AND RESTATED
CERTIFICATE OF INCORPORATION TO CHANGE THE
NAME OF VEECO INSTRUMENTS INC. TO VEECO FEI INC.

        At the Veeco special meeting, the Veeco stockholders will be asked to consider and vote upon a proposal, unanimously recommended and determined to be advisable by Veeco's board of directors, to amend Article 1 of Veeco's Amended and Restated Certificate of Incorporation, to change the name of Veeco Instruments Inc. to Veeco FEI Inc. Veeco has agreed and is obligated to change its corporate name under the terms of the merger agreement.

        Assuming the approval of the proposed amendment to Veeco's Amended and Restated Certificate of Incorporation and the completion of the merger, it is anticipated that Veeco will file the amendment immediately after the closing of the merger. A vote in favor of this proposal to amend Veeco's Amended and Restated Certificate of Incorporation will not be deemed to be a vote to approve the issuance of shares in the merger, the proposed amendment to Veeco's Amended and Restated Certificate of Incorporation relating to the increase in the authorized shares of Veeco common stock or the proposed amendment to Veeco's First Amended and Restated Employee Stock Purchase Plan relating to the increase in shares of Veeco common stock issuable under the plan.

        If Veeco's stockholders do not approve the proposed amendment to Veeco's Amended and Restated Certificate of Incorporation, Veeco could be deemed to be in violation of contractual provisions in the merger agreement which, if deemed material, could give rise to FEI's right to obtain damages under the merger agreement.

        The full text of the proposed amendment to Veeco's Amended and Restated Certificate of Incorporation is set forth in Appendix F-2 hereto and the description of the proposed amendment herein is qualified in its entirety by reference to such Appendix F-2.

        The affirmative vote of the holders of a majority of the outstanding shares of Veeco common stock entitled to vote thereon will be required to amend Veeco's Amended and Restated Certificate of Incorporation to change the name of Veeco Instruments Inc. to Veeco FEI Inc.

        The board of directors of Veeco believes that approval of this amendment to Veeco's Amended and Restated Certificate of Incorporation is in the best interests of Veeco and Veeco's stockholders and determined that this amendment is advisable. The board of directors of Veeco unanimously recommends a vote "FOR" approval of the amendment to change the name of Veeco Instruments Inc. to Veeco FEI Inc. as described above at Veeco's special meeting. In the event that this proposed amendment and the proposed amendment to increase the number of authorized shares of Veeco common stock are not approved by Veeco's stockholders at the Veeco special meeting, the Amended and Restated Certificate of Incorporation in effect as of the date hereof will remain in full force and effect.

107


AMENDMENT TO VEECO'S FIRST AMENDED AND RESTATED
EMPLOYEE STOCK PURCHASE PLAN

        On June 15, 1995, a majority of Veeco's stockholders adopted an employee stock purchase plan under which 250,000 shares of Veeco common stock were reserved for issuance to Veeco employees. On October 26, 2000, the Veeco board of directors adopted Veeco's First Amended and Restated Employee Stock Purchase Plan. On October 24, 2002, the Veeco board of directors approved an amendment to Veeco's First Amended and Restated Employee Stock Purchase Plan, subject to the approval of Veeco's stockholders.

        At the Veeco special meeting, the Veeco stockholders will be asked to consider and vote upon a proposal, unanimously recommended and determined to be advisable by Veeco's board of directors, to amend Veeco's First Amended and Restated Employee Stock Purchase Plan. The amendment will increase the number of shares issuable under the existing plan by 500,000 shares to a total number of 750,000 shares of Veeco common stock. The plan currently provides for the issuance of an aggregate of 250,000 shares, of which 78,155 shares remain available for issuance. Based on employee participation levels so far in 2002, Veeco expects to exhaust the remaining available shares upon the annual purchase following the end of 2002. Absent the proposed amendment, Veeco may have to cut-back the employee participation levels so as to not exceed the number of shares available for issuance at the time of the annual purchase following the end of 2002. The Veeco board of directors believes that increasing the number of shares that may be purchased under the plan is necessary to permit broad participation by employees in the plan. In the judgment of the Veeco board of directors, having too few shares eligible for issuance under the plan would reduce the number of purchases that could be made under the plan and would therefore reduce the extent to which employees could participate in the plan. If the merger is completed, FEI employees would also be able to participate in the plan, and the need for additional shares available for issuance under the plan would be increased. A vote in favor of this amendment to Veeco's First Amended and Restated Employee Stock Purchase Plan will not be deemed to be a vote to approve the issuance of shares in the merger or the proposed amendments to Veeco's Amended and Restated Certificate of Incorporation.

Description of First Amended and Restated Employee Stock Purchase Plan, as Amended

        The following is a summary of the plan as in effect on the date hereof as well as the amendment currently proposed. This summary of the existing plan is qualified in its entirety by reference to the complete text of the plan as previously filed by Veeco as an exhibit to its Annual Report on Form 10-K for the year ended December 31, 2000. Copies of the complete plan may be obtained in the manner described under "Where You Can Find More Information" below. A copy of the proposed amendment is attached as Appendix I to this joint proxy statement/prospectus. As this plan will be the employee stock purchase plan for the combined company following the merger, Veeco stockholders and FEI shareholders are encouraged to read the summary of the proposed plan.

        Purpose and Eligibility.    Veeco's First Amended and Restated Employee Stock Purchase Plan, as amended, is intended to provide an incentive to eligible employees of Veeco and any direct or indirect subsidiary of Veeco to have a greater interest in Veeco's growth by providing them with the opportunity to purchase Veeco common stock at favorable prices by means of payroll deductions. Each employee of Veeco or an affiliate of Veeco whose customary employment is expected to be at least 20 hours per week and more than five months per year, other than an employee who owns beneficially (or holds options to purchase) five percent or more of Veeco's total combined voting power or value of all classes of stock, will be eligible to participate in the plan. The approximate number of persons eligible to participate is 1,100. If the merger occurs, approximately 2,600 persons will be eligible to participate.

        Administration.    The plan shall be administered by the compensation committee of the Veeco board of directors. The committee shall consist of at least three directors appointed by the Veeco board of directors. All members of the committee shall be "disinterested persons" within the meaning of

108


Rule 16b-3 of the Exchange Act and "outside directors" within the meaning of Section 162(m) of the Internal Revenue Code and shall not be eligible to participate in the plan. Subject to the express provisions of the plan, the committee shall have authority to interpret the terms and provisions of the plan, to adopt, amend and repeal such rules, regulations, agreements and instruments for implementing and administering the plan as it deems necessary or advisable and to make all other determinations and take all other actions necessary or advisable for the implementation and administration of the plan. The committee may also delegate its administrative duties to such other persons as it deems appropriate in administering the plan. All decisions made by the committee shall be binding and conclusive on all persons who have an interest under the plan.

        Deferral of Compensation.    Each person electing to participate in the plan must file a payroll deduction authorization with the administrator of the plan named by the committee, or his or her delegate, which indicates the amount to be deducted from the participant's paychecks. This deduction must be between 1% and 10% of the participant's base pay or such other percentage as may be established by the administrator of the plan.

        Offering and Purchase of Stock.    Offering periods to purchase Veeco common stock will begin on January 1 and end on December 31 of each calendar year. In the case of an employee who is eligible to participate in the plan after November 30 and before the following June 1, the initial offering period for such participant will be the six-month period beginning on the following July 1 and ending December 31.

        During an offering period, the purchase price of the Veeco common stock shall be the lesser of:

Unless a participant elects to withdraw prior to the close of an offering period, a participant's election to purchase stock shall be deemed to be exercised automatically on the last day of the offering period.

        The number of shares of Veeco common stock purchased by a participant upon exercise shall be equal to (i) the amount credited to a participant's account as of the close of the offering period divided by (ii) the purchase price per share of Veeco common stock. No participant shall be permitted to purchase stock with an aggregate fair market value in excess of $25,000 for any given offering period. The plan provides that, if any balance remains credited to a participant's account after exercise of the participant's option, Veeco shall pay an amount to the participant equal to such balance.

        Reduction and Discontinuation of Payroll Deductions.    A participant may elect to reduce his or her level of payroll deductions during an offering period at any time prior to November 30. A participant may make only one such election during an offering period, absent specific approval by the administrator of the plan. A participant may elect to discontinue his or her payroll deductions during an offering period at any time prior to November 30. A participant who elects to discontinue payroll deductions for an offering period may not again resume payroll deductions for that offering period.

        Withdrawal.    A participant may withdraw from an offering at any time prior to November 30. A participant who withdraws from an offering may not again participate in that offering, but a participant's withdrawal will not have any effect upon such participant's eligibility to participate in any succeeding offering. Upon withdrawal from the plan, the balance in the participant's stock purchase account will be returned to the participant.

        In the event that a participant's employment is terminated for any reason other than death prior to the close of an offering, the participant will be considered to have withdrawn from the offering. In the event that a participant's employment is terminated because of such participant's death prior to the close of an offering, such participant's beneficiary shall have the right to elect to:

109

        Adjustment.    If the number of shares of Veeco common stock outstanding is increased or decreased or changed into or exchanged for a different number or kind of shares or other securities of Veeco or of another corporation by reason of reorganization, merger, consolidation, recapitalization, reclassification, stock split, reverse stock split, combination of shares, or dividend payable in shares of Veeco common stock, the number of shares for which offerings may be made under the plan shall be increased or decreased proportionately, as the case may be, and the committee shall make the appropriate adjustment in the number and kind and price of shares subject to offerings then outstanding and unexercised.

        Amendment and Termination.    Veeco's board of directors or the compensation committee may amend, modify or terminate the plan; provided, however, that the Veeco board of directors or the committee may not, without stockholder approval:

        Federal Income Tax Consequences.    The following discussion is a brief summary of the principal United States federal income tax consequences under current federal income tax laws relating to awards under the plan. This summary is not intended to be complete and, among other things, does not describe state, local or foreign income and other tax consequences. PARTICIPANTS IN THE PLAN ARE URGED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE CONSEQUENCES OF THEIR PARTICIPATION IN THE PLAN.

        The plan is intended to qualify as an "employee stock purchase plan" within the meaning of Section 423(b) of the Internal Revenue Code. The plan is not subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended, and is not qualified under Section 401(a) of the Internal Revenue Code. No income will be taxable to a participant until the shares purchased under the plan are sold or otherwise disposed. If the shares are sold or otherwise disposed of more than two years from the applicable offering date and more than one year from the date of transfer of the shares to the participant, then the participant generally will recognize ordinary income measured as the lesser of:

        If the shares are sold or otherwise disposed of before the expiration of this holding period, the participant will recognize ordinary income generally measured as the excess of the fair market value of the shares on the date the shares are purchased over the purchase price; any additional gain or loss on a sale or disposition will be long-term or short-term capital gain or loss, depending on the holding period. There are special rules for recognizing income that apply in the case of death. Veeco is not entitled to a deduction for amounts taxed as ordinary income or capital gain to a participant except to the extent ordinary income is recognized by participants upon a sale or disposition of shares prior to the expiration of the holding periods described above. In all other cases, no deduction is allowed to Veeco.

        Plan Benefits.    Because the number of shares of Veeco common stock to be granted in the future under the plan is contingent upon the number of employees who elect to participate in the plan, it is

110


not possible to determine the benefits or the amounts received under the plan by Veeco's officers and employees.

        A majority of the votes cast at Veeco's special meeting (including votes cast by proxy) must vote "FOR" the proposed amendment to Veeco's First Amended and Restated Employee Stock Purchase Plan in order for the proposal to be approved by Veeco stockholders.

        The Veeco board of directors believes that approval of the amendment to Veeco's First Amended and Restated Employee Stock Purchase Plan is in the best interests of Veeco and Veeco's stockholders and determined that this proposal to adopt such plan is advisable. The Veeco board of directors unanimously recommends a vote "FOR" approval of the proposed amendment to Veeco's First Amended and Restated Employee Stock Purchase Plan. In the event that this proposed amendment to Veeco's First Amended and Restated Employee Stock Purchase Plan is not approved by Veeco's stockholders at the Veeco special meeting, Veeco's First Amended and Restated Employee Stock Purchase Plan as in effect on the date hereof will remain in full force and effect.

UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

        The unaudited pro forma consolidated financial statements are based upon the historical consolidated financial statements and notes thereto (as applicable) of Veeco and FEI, which are incorporated by reference herein. The unaudited consolidated balance sheet gives pro forma effect to the merger as if it had been consummated on June 30, 2002 and combines Veeco's June 30, 2002 unaudited consolidated balance sheet with FEI's June 30, 2002 unaudited consolidated balance sheet. The unaudited pro forma consolidated statements of operations give pro forma effect to the merger as if it had been consummated on January 1, 2001 and combine Veeco's consolidated statement of operations for the year ended December 31, 2001 with FEI's consolidated statement of operations for the year ended December 31, 2001 and Veeco's unaudited consolidated statements of operations for the six months ended June 30, 2001 and 2002, respectively, with FEI's unaudited consolidated statements of operations for the twenty-six weeks ended July 1, 2001 and June 30, 2002, respectively. The pro forma adjustments are subject to change pending a final analysis of fair values of the assets acquired and liabilities assumed. The impact of these changes could be material.

        In addition, on September 17, 2001, a wholly-owned subsidiary of Veeco merged with and into Applied Epi, Inc. of St. Paul, Minnesota. As a result of that merger, Applied Epi became a wholly-owned subsidiary of Veeco. The unaudited pro forma consolidated statements of operations for the six months ended June 30, 2001 and for the year ended December 31, 2001 give effect to the acquisition of Applied Epi by Veeco as if it occurred on January 1, 2001.

        The unaudited pro forma consolidated financial statements are based upon the estimates and assumptions set forth in the notes to the unaudited pro forma consolidated financial statements. The pro forma adjustments (including estimates and assumptions) made in connection with the preparation of the pro forma information are preliminary and have been made solely for purposes of preparing such pro forma information for illustrative purposes necessary to comply with the disclosure requirements of the SEC. The unaudited pro forma consolidated financial statements do not purport to be indicative of the results of operations for future periods or the consolidated financial position or results that actually would have been realized for the periods presented had Veeco and FEI been a single entity during these periods. The unaudited pro forma consolidated financial statements do not give effect to any synergies, cost savings or integration costs that may result from the integration of Veeco's and FEI's businesses. Costs associated with the Veeco FEI transaction related to restructuring and integration have not yet been determined. In addition, FEI's operating costs have increased and may further increase due to the termination (and expected termination) of some of the tangible and intangible benefits and arrangements provided to FEI by Philips. Certain of these benefits and arrangements terminated prior to June 30, 2002 and a portion of these increased costs resulting therefrom have already been incurred by FEI. FEI has also received payments described herein from Philips which have offset certain of these increased costs and have been recorded by FEI as a reduction in costs and operating expenses. The unaudited pro forma consolidated financial statements exclude the effects of a portion of the additional operating costs which may be incurred in connection with the termination of certain arrangements between FEI and Philips, which costs cannot reasonably be estimated at this time. In addition, the unaudited pro forma consolidated financial statements exclude the effect of a portion of the increased additional pension costs which will be incurred in connection with FEI's new collective bargaining agreements, which took effect September 1, 2001. For more information concerning these additional costs, see the sections titled "Risk Factors—The combined company will be subject to increased operational costs and other risks because PBE no longer owns a majority of FEI's common stock" beginning on page 27 and "Relationship with Philips" beginning on page 100.

        These unaudited pro forma consolidated financial statements should be read in conjunction with the historical consolidated financial statements and the related notes thereto of Veeco and FEI, which are incorporated by reference herein.

NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

Note 1—Pro forma Balance Sheet Adjustments

        On July 11, 2002, Veeco, Venice Acquisition Corp., a wholly-owned subsidiary of Veeco, and FEI entered into a merger agreement providing for the merger of Venice Acquisition Corp., with and into FEI Company. Upon completion of the merger, FEI will become a wholly-owned subsidiary of Veeco. The acquisition will be accounted for as a purchase. Under the merger agreement, FEI shareholders will receive an aggregate of approximately 44.1 million shares of Veeco common stock and exchange and assume options of FEI for options to purchase approximately 4.2 million shares of Veeco's common stock and approximately 0.4 million shares of Veeco common stock issuable to PBE in connection with the investor agreement. The assumed options and shares issuable to PBE will be recorded at fair value. Veeco will also incur approximately $20.0 million of acquisition related transaction costs. The merger consideration is computed as follows (dollars in thousands):

Fair market value of shares issued   $ 844,037
Fair value of stock options assumed     62,850
Transaction costs     20,000
   
Total purchase price   $ 926,887
   

        The fair market value of the shares issued is based upon the average closing market price of Veeco common stock during the five-day period surrounding the announcement of the merger. The fair value of stock options assumed is determined by using a Black-Scholes option-pricing model.

        The fair value of the net assets acquired were estimated as follows for the purpose of preparing the pro forma balance sheet (dollars in thousands):

Tangible assets   $ 613,381  
In-process technology     35,920  
Goodwill     488,401  
Amortizable intangible assets     194,074  
   
 
Total assets     1,331,776  
Liabilities assumed     (404,889 )
   
 
Total purchase price   $ 926,887  
   
 

        The fair value of the net assets acquired was established based upon the unaudited June 30, 2002 consolidated balance sheet of FEI, as well as certain assumptions made by Veeco management regarding the difference between the historical value and the fair value of the net assets acquired.

        The following notes explain the pro forma adjustments. The pro forma information excludes the effect of the potential issuance of up to 4,788,470 shares of Veeco common stock, in the aggregate, upon the conversion of FEI's $175 million principal amount of 5.5% convertible subordinated notes due August 15, 2008, which notes will become convertible into Veeco common stock at the time of the merger.

Note 2—Pro forma Statements of Operations Adjustments

        Details of the pro forma adjustments relating to the Veeco FEI merger and the Veeco/Applied Epi merger are set forth below:

118

        The pro forma adjustments in the statements of operations do not give effect to the impact on gross profit of the adjustment to increase inventory by $20.5 million to its estimated fair value and the impact on sales and gross profit of the adjustment to reduce deferred gross profit by approximately $7.2 million to its estimated fair value. Such adjustments, which are reflected in the June 30, 2002 balance sheet, are required under the purchase method of accounting in accordance with regulation S-X.

COMPARISON OF RIGHTS OF VEECO STOCKHOLDERS
AND RIGHTS OF FEI SHAREHOLDERS

        This section describes some of the differences as well as some of the similarities between the rights of holders of Veeco common stock and those of holders of FEI common stock. While we believe that the description covers the material differences between the two, this summary may not contain all of the information that is important to you, including information set forth in the Amended and Restated Certificate of Incorporation of Veeco, Articles of Incorporation of FEI and bylaws of each company. You should carefully read this entire joint proxy statement/prospectus and the other documents we refer to for a more complete understanding of the differences between the rights of holders of Veeco common stock and those of holders of FEI common stock. You may obtain the information incorporated by reference without charge by following the instructions in the section titled "Where You Can Find More Information" beginning on page 134.

        When Veeco and FEI complete the merger, FEI shareholders will become Veeco stockholders. FEI shareholders currently are governed by the Oregon Business Corporation Act and FEI's Amended and Restated Articles of Incorporation and Restated Bylaws. After the merger, the rights of FEI shareholders who receive common stock of Veeco will be governed by the Delaware General Corporation Law and Veeco's Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws as in effect at the closing of the merger.

Description of Capital Stock

        Veeco.    Veeco's amended and restated certificate of incorporation authorizes Veeco to issue up to 60,500,000 shares of capital stock, consisting of two classes: 60,000,000 shares of common stock, $0.01 par value per share, and 500,000 shares of preferred stock, $0.01 par value per share, 30,000 shares of which have been designated as series A junior participating preferred stock in connection with the Veeco stockholder rights plan. With respect to Veeco's undesignated preferred stock, Veeco's board of directors is authorized, without stockholder approval, to designate one or more series of preferred stock and to determine the number of shares included in any series and the designation, powers, preferences and rights of the shares of each such series and the qualifications, limitations or restrictions thereof. On June 30, 2002, there were 29,134,679 shares of Veeco common stock and no shares of Veeco preferred stock issued and outstanding.

        FEI.    FEI's articles of incorporation authorize FEI to issue up to 45,500,000 shares of capital stock, consisting of two classes: 45,000,000 shares of common stock, no par value, and 500,000 shares of preferred stock, no par value per share. With respect to FEI's undesignated preferred stock, FEI's board of directors is authorized to designate one or more series of preferred stock and to determine the number of shares included in any series and the designation, preferences, limitations and relative rights of the shares of any series. The FEI board of directors is also authorized to increase or decrease the number of shares of any series of preferred stock subsequent to the issuance of shares of that series, subject to certain limitations. On June 30, 2002, there were 32,393,766 shares of FEI common stock and no shares of FEI preferred stock issued and outstanding.

Voting Rights

        Veeco.    Veeco's bylaws provide that each Veeco stockholder has the right to one vote for each share of Veeco common stock registered in the stockholder's name on each matter submitted to a stockholder vote. Generally, other than the election of directors, who are elected by a plurality vote, and except as otherwise provided by the Delaware General Corporation Law, all matters to be voted on by Veeco stockholders must be approved by a majority of the votes cast. The Delaware General Corporation Law provides that a certificate of incorporation may allow cumulative voting for election of directors of a corporation or elections held under specified circumstances. Veeco's Amended and Restated Certificate of Incorporation does not provide for cumulative voting.

        FEI.    FEI's articles of incorporation provide that each FEI shareholder has the right to one vote for each share of FEI common stock registered in the shareholder's name on each matter submitted to

120

a shareholder vote. The FEI bylaws specify that, other than the election of directors and except as otherwise provided by the FEI articles of incorporation or by the Oregon Business Corporation Act, all matters to be voted on by FEI shareholders will be approved if the votes cast by shares entitled to vote favoring the action exceed the votes cast opposing the action. Unless otherwise provided in the FEI articles of incorporation, directors are elected by a plurality of the votes cast by shares entitled to vote in the election at a meeting at which a quorum is present. The Oregon Business Corporation Act provides that articles of incorporation may allow cumulative voting for elections of directors of a corporation. FEI's articles of incorporation do not provide for cumulative voting.

Stockholder Actions Generally

        Veeco.    Veeco's bylaws provide that, at each meeting of stockholders, the presence in person or by proxy of the holders of 50% of the shares entitled to vote shall constitute a quorum for the transaction of any business.

        FEI.    FEI's bylaws provide that, at each meeting of shareholders, the presence in person or by proxy of the holders of a majority of the shares entitled to vote shall constitute a quorum for the transaction of any business.

Special Meetings of Stockholders

        Veeco.    Under Delaware law, a special meeting of stockholders may be called by the board of directors or any other person as may be provided in the certificate of incorporation or bylaws. Veeco's bylaws provide that special meetings of the Veeco stockholders may be called at any time by Veeco's board of directors or by the President or Chief Executive Officer of Veeco and shall be called by the President, Chief Executive Officer or Secretary of Veeco upon the written request of a majority of Veeco's board of directors then in office or of 50% of the outstanding Veeco shares entitled to vote. Only business related to the purposes set forth in the notice of the meeting may be transacted at a special meeting.

        FEI.    Oregon law provides that a special meeting of shareholders may be called by the holders of at least ten percent (10%) of all the votes entitled to be cast on any issue proposed to be considered at the proposed special meeting, or by a corporation's board of directors, or by such other persons as are authorized under the corporation's articles of incorporation or bylaws. FEI's bylaws provide that special meetings of FEI shareholders may be called by the President or by the board of directors of FEI and shall be called by the President of FEI at the request of not less than one-tenth of all outstanding shares of FEI entitled to vote at the meeting.

Action by Written Consent in Lieu of a Stockholder Meeting

        Veeco.    Under Delaware law, unless otherwise provided in the certificate of incorporation, any action which may be taken at a meeting of stockholders may be taken without a meeting and without prior notice if a consent in writing is signed by the holders of outstanding shares having at least the minimum number of votes that would be necessary to take such action at a meeting at which all shares entitled to vote thereon were present and voted. Veeco's bylaws provide that no action required or permitted to be taken at any meeting of stockholders may be taken by written consent without a meeting.

        FEI.    Under Oregon law, any action required or permitted to be taken at a meeting of the shareholders may be taken without a meeting if the action is taken by all shareholders entitled to vote on the action. The action must be evidenced by one or more written consents describing the action taken and signed by all the shareholders entitled to vote on the action. FEI's bylaws provide that action required or permitted by law to be taken at a shareholders' meeting may be taken without a meeting if the action is taken by all the shareholders entitled to vote on the action and evidenced by one or more written consents signed by all the shareholders entitled to vote on the action.

121

Appraisal/Dissenters' Rights

        Veeco.    Under Delaware law, a stockholder of a corporation participating in certain major corporate transactions may, under varying circumstances, be entitled to dissenters' rights or to appraisal rights pursuant to which such stockholder may receive cash in the amount of the fair market value of the shares held by such stockholder (as determined by a court or by agreement of the corporation and the stockholder) in lieu of the consideration such stockholder would otherwise receive in the transaction. Under Delaware law, such fair market value is determined exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, and such appraisal rights are not available in the following situations:

        FEI.    Under Oregon law, a shareholder is entitled to dissent from, and obtain payment of the fair value of the shareholder's shares in the event of, any of the following corporate acts: (1) consummation of a plan of merger to which the corporation is a party if shareholder approval is required and the shareholder is entitled to vote on the merger or if the corporation is a subsidiary that is merged with its parent; (2) consummation of a plan of share exchange to which the corporation is a party as the corporation whose shares will be acquired, if the shareholder is entitled to vote on the plan; (3) consummation of a sale or exchange of all or substantially all of the property of the corporation other than in the usual and regular course of business if the shareholder is entitled to vote on the sale or exchange, unless the sale is for cash pursuant to which all or substantially all of the net proceeds will be distributed to shareholders within one year; (4) an amendment of the articles of incorporation that materially and adversely affects rights in respect of a dissenter's shares because it (A) alters or abolishes a preemptive right of the holder of the shares to acquire shares or other securities or (B) reduces the number of shares owned by the shareholder to a fraction of a share if the fractional share so created is to be acquired for cash under Oregon law; or (5) any corporate action taken pursuant to a shareholder vote to the extent the articles of incorporation, bylaws or a resolution of the board of directors provides that voting or nonvoting shareholders are entitled to dissent and obtain payment for their shares. Unless the articles of incorporation provide otherwise, dissenters' rights do not apply to the holders of shares of any class or series if the shares of the class or series were registered on a national securities exchange or quoted on The Nasdaq National Market on the record date for the meeting of shareholders at which the corporate action giving rise to dissenters' rights is to be approved.

Record Date for Determining Stockholders

        Veeco.    Veeco's bylaws provide that Veeco's board of directors may fix a record date that is not more than 60 nor less than 10 days before the date of a Veeco stockholders meeting or more than 60 days before any other action.

        FEI.    FEI's bylaws provide that FEI's board of directors may fix, in advance, a record date that is not more than 70 nor less than 10 days before the date of an FEI shareholders meeting. A determination of shareholders entitled to notice of or to vote at a shareholders meeting is effective for any adjournment of the meeting unless FEI's board of directors fixes a new record date, which it must do if the meeting is adjourned to a date more than 120 days after the date fixed for the original

122

meeting. If a court orders a meeting adjourned to a date more than 120 days after the date fixed for the original meeting, it may provide that the original record date continue in effect or it may fix a new record date.

Notice of Meetings

        Veeco.    Veeco's bylaws provide that written notice of each meeting of Veeco's stockholders shall be given to each Veeco stockholder entitled to vote at the meeting, except that:

Each notice of a meeting shall be given, personally or by mail, not less than 10 nor more than 60 days before the meeting and shall state the time and place of the meeting, and unless it is the annual meeting, shall state at whose direction or request the meeting is called and the purposes for which it is called.

        FEI.    FEI's bylaws provide for notice provisions similar to those of Veeco's bylaws with respect to meetings of FEI shareholders, although its bylaws specify that no notice of an adjourned meeting need be given unless the FEI board of directors fixes a new record date more than 120 days after the date fixed for the original meeting.

Annual Meeting

        Veeco.    Veeco's bylaws specify that the annual meeting of Veeco's stockholders shall be held at a place and time determined by Veeco's board of directors. At the Veeco annual meeting, Veeco's stockholders elect directors and transact any other business that is properly brought before the meeting and described in the notice of meeting.

        FEI.    FEI's bylaws provide that the annual meeting of FEI's shareholders shall be held on the third Wednesday in May in each year at 10:00 a.m., unless a different date and time are fixed by the FEI board of directors and stated in the notice of the meeting.

Number, Class and Term of Directors

        Veeco.    Veeco's bylaws provide that Veeco's board of directors shall be divided into three classes with staggered three-year terms. As a result, only one of the three classes of Veeco's board of directors will be elected each year. Veeco's bylaws provide that the exact number of the directors on the board of directors shall be not less than three, nor more than fifteen, the exact number of which shall be determined from time to time by resolution of Veeco's board of directors. Directors shall be elected at each annual meeting of Veeco's stockholders and shall hold office until the election and qualification of his or her successor or until his or her earlier resignation or removal by vote of Veeco's stockholders. As of the date of the mailing of this joint proxy statement/prospectus, Veeco's board of directors was comprised of nine directors.

        Upon completion of the merger, the board of directors of Veeco FEI will be comprised of 13 individuals, seven of whom will be nominated by Veeco, five of whom will be nominated by FEI and one of whom will be nominated by PBE pursuant to the terms of an investor agreement among Veeco, FEI and PBE.

        FEI.    FEI's bylaws provide that FEI's board of directors must be composed of between six and eleven directors, as fixed by the FEI board of directors or shareholders. As of the date of the mailing of this joint proxy statement/prospectus, the FEI board of directors had eight directors. The FEI board of directors is not classified into separate classes. The directors are elected each year at the annual meeting of shareholders.

123

Election of Directors

        Veeco and FEI.    The holders of Veeco and FEI common stock elect all members of their respective boards of directors. Veeco and FEI directors are elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors.

Resignation and Removal of Directors

        Veeco.    Veeco's bylaws provide that any Veeco director may resign at any time upon written notice to the Chief Executive Officer or Secretary of Veeco and be removed, with cause, by vote of Veeco's stockholders.

        FEI.    FEI's bylaws provide that any director may be removed from the FEI board of directors at any meeting of the shareholders called for that purpose by a majority of the FEI common stock represented and entitled to vote at the meeting. Any director may resign by delivering written notice to the FEI board of directors, its chairperson or to FEI. Such resignation shall be effective:

Once delivered, a notice of resignation is irrevocable unless revocation is permitted by the FEI board of directors.

Board of Directors Vacancies

        Veeco.    Veeco's bylaws state that any vacancy on the Veeco board of directors, including any newly created Veeco directorship resulting from an increase in the number of Veeco directors, may be filled only by the vote of a majority of the remaining Veeco directors, though less than a quorum.

        FEI.    FEI's bylaws provide that vacancies on the FEI board of directors may be filled by the shareholders, the FEI board of directors or the vote of a majority of the remaining directors if the remaining directors constitute less than a quorum of the FEI board of directors or by a sole remaining director. A director so elected to fill a vacancy serves until the next annual meeting of shareholders and until the director's successor is elected and qualified.

Annual Meeting of the Board of Directors

        Veeco.    Veeco's bylaws provide that annual meetings of the Veeco board of directors, for the election of officers and consideration of other matters, shall be held either:

        FEI.    FEI's bylaws state that the annual meeting of the FEI board of directors shall be held without notice other than FEI's bylaws, immediately after, and at the same place as, the annual meeting of shareholders.

Notice of Special Meetings of the Board of Directors

        Veeco.    Veeco's bylaws state that special meetings of Veeco's board of directors may be called by the Chief Executive Officer of Veeco or by a majority of the entire Veeco board of directors. Notice of the time and place of each special meeting of Veeco's board of directors shall be given to each Veeco

124

director by mailing it to him at his residence or usual place of business at least three days before the meeting, or by delivering or telephoning or telecopying it to him at least two days before the meeting. Notice of a special meeting of Veeco's board of directors shall also state the purpose or purposes for which the meeting is called.

        FEI.    FEI's bylaws state that special meetings of the board of directors of FEI may be called at the direction of the President of FEI or by a majority of FEI directors then in office. Notice of the date, time and place of any special meetings of the FEI board of directors shall be given in a manner reasonably likely to be received at least three days prior to the meeting by any means provided by law. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the FEI board of directors need be specified in the notice or waiver of notice of such meeting.

Board Action

        Veeco.    Veeco's bylaws provide that a majority of the entire board of directors shall constitute a quorum for the transaction of business at any meeting. Action of the board of directors shall be authorized by the vote of a majority of the directors present at the time of the vote if there is a quorum, unless otherwise provided in Veeco's bylaws or by applicable law. In the absence of a quorum, a majority of the directors present may adjourn any meeting from time to time until a quorum is present.

        FEI.    FEI's bylaws provide that a majority of the number of directors shall constitute a quorum for the transaction of business at any meeting of the FEI board of directors. The act of the majority of the directors present at a meeting at which a quorum is present shall be the act of the FEI board of directors, unless a different number is provided by law, or by FEI's articles of incorporation or bylaws.

Actions in Writing; Participation by Conference Telephone

        Veeco and FEI.    Both Veeco's and FEI's bylaws provide that:

Action by Committees

        Veeco.    Veeco's bylaws create the following committees, with the following powers and duties:

125

        Veeco's bylaws also provide that the Veeco board of directors may designate one or more directors as alternate members of any Veeco committee, who may replace any absent or disqualified member. In the absence or disqualification of any member of a Veeco committee, the member or members present at a meeting of the committee and not disqualified, whether or not a quorum, may unanimously appoint another Veeco director to act at the meeting in place of the absent or disqualified member. All action of a Veeco committee shall be reported to the Veeco board of directors at its next meeting.

        FEI.    Unless FEI's articles of incorporation provide otherwise, FEI's bylaws authorize the FEI board of directors to create one or more committees and appoint members of the FEI board of directors to serve on them. Each committee shall have two or more members, who serve at the direction of the FEI board of directors. A majority of all directors in office must approve the creation of a committee and the appointment of its members. The creation of a committee, the delegation of authority to it or action by a committee shall not alone constitute compliance by a director with standards of conduct prescribed by law. No member of any committee shall continue to be a member thereof after ceasing to be an FEI director. The FEI board of directors shall have the power at any time to increase or decrease the number of members of any committee, to fill vacancies thereon, to change any member thereof and to change the functions or terminate the existence thereof.

        A committee shall not have the authority of the FEI board of directors in reference to:

        FEI has the following standing committees with the following powers and duties:

126

Amendment of Certificate of Incorporation and Articles of Incorporation

        Veeco.    Section 242 of the Delaware General Corporation Law authorizes a corporation to amend its certificate of incorporation in any way so long as the certificate of incorporation, as amended, would only contain provisions lawful and proper for insertion in an original certificate of incorporation. Section 242 of the Delaware General Corporation Law requires that, to amend a certificate of incorporation:

        FEI.    The FEI board of directors may make specified minor changes to FEI's articles of incorporation without shareholder action. In general, other amendments to FEI's articles of incorporation must be recommended to FEI shareholders by the FEI board of directors and approved by a majority of the votes entitled to be cast by any voting group with which the amendment would create dissenters' rights and a majority of the shares that have a right to vote on the amendment, unless a higher percentage is specified by the Oregon Business Corporation Act, FEI's articles of incorporation or the FEI board of directors.

Amendment of Bylaws

        Veeco and FEI.    The bylaws of both Veeco and FEI provide that FEI's and Veeco's respective boards of directors have the power to adopt, amend or repeal their respective bylaws. The stockholders of Veeco and the shareholders of FEI also have the power to adopt, amend or repeal their respective bylaws. The bylaws of Veeco FEI will require a vote of two-thirds of the entire board of directors to amend, alter or repeal the provisions of Veeco FEI's bylaws relating to the resignation and removal of, and the roles of, the President and Chief Executive Officer and Chairman.

Dividends and Repurchase of Shares

        Veeco.    Delaware law permits a corporation to declare and pay dividends out of surplus or, if there is no surplus, out of net profits for the fiscal year in which the dividend is declared and/or for the preceding fiscal year. If the amount of capital of the corporation following the declaration and payment of the dividend is less than the aggregate amount of the capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets, the directors may not declare and pay out a dividend from the corporation's net profits. In addition, Delaware law generally provides that a corporation may redeem or repurchase its shares only if the capital of the corporation is not impaired and such redemption or repurchase would not impair the capital of the corporation.

        FEI.    Under Oregon law, the board of directors of a corporation may authorize and the corporation may make distributions (including dividends) to shareholders only if after giving effect to the distribution (1) the corporation would be able to pay its debts as they become due in the usual course of business and (2) the corporation's total assets would at least equal the sum of the total liabilities plus, unless the corporation's articles of incorporation permit otherwise, the amount that would be needed if the corporation were to be dissolved at the time of the distribution to satisfy the

127


preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the distribution.

Limitation of Director Liability

        Veeco and FEI.    The Veeco certificate of incorporation and the FEI bylaws limit the liability of Veeco's and FEI's respective directors to the fullest extent permitted by the Delaware General Corporation Law and Oregon Business Corporation Act, respectively.

Indemnification

        Veeco.    Veeco's Amended and Restated Certificate of Incorporation and bylaws provide that its directors, officers, employees and agents shall be indemnified to the fullest extent authorized by the Delaware General Corporation Law.

        FEI.    FEI's bylaws provide that FEI shall indemnify to the fullest extent not prohibited by law any current or former officer or director who is made, or threatened to be made, a party to an action, suit or proceeding, whether civil, criminal, administrative, investigative or otherwise (including an action, suit or proceeding by or in the right of FEI) by reason of the fact that the person is or was acting as a director, officer or agent of FEI or as a fiduciary within the meaning of the Employee Retirement Income Security Act of 1974 with respect to any employee benefit plan of FEI, or serves or served at the request of FEI as a director or officer, or as a fiduciary of an employee benefit plan, of another corporation, partnership, joint venture, trust or other enterprise. The indemnification shall not be deemed exclusive of any other rights to which such person may be entitled under any bylaw, agreement, vote of shareholders or disinterested directors or otherwise, both as to action in the official capacity of the person indemnified and as to action in another capacity while holding such office.

Interested Director Transactions

        Veeco.    The Veeco amended and restated certificate of incorporation does not specifically address interested director transactions. Under the Delaware General Corporation Law, certain contracts or transactions in which one or more of the directors of Veeco has an interest are void or voidable unless:

        FEI.    The FEI articles of incorporation do not specifically address interested director transactions. Under the Oregon Business Corporation Act, a conflict of interest transaction is not voidable by FEI solely because of a director's interest in the transaction if:

128

Interested Stockholder Transactions

        Veeco and FEI.    Veeco and FEI are subject to the provisions of the Delaware General Corporation Law and the Oregon Business Corporation Act, respectively, which both prohibit a corporation from engaging in a business combination with an interested stockholder for three years following the date the stockholder became an interested stockholder. The Delaware General Corporation Law specifically excepts such business combinations where:

        A business combination is defined to include:

        Generally, an interested stockholder is a person who, together with its affiliates and associates, owns 15% or more of the corporation's voting stock or owned 15% of such voting stock within three years before the proposed business combination, or is affiliated with the corporation.

        Although the Oregon business combination statute generally replicates Delaware's business combination statute, the Oregon statute omits a significant provision dealing with competitive bidding contests for corporate control. Section 203(b)(6) of the Delaware General Corporation Law generally relieves a bidder from the restrictions of the business combination statute if the board of directors has approved or not opposed a combination with a competing bidder. The basic policy behind Section 203(b)(6) is that once the board of directors has decided to sell the corporation or a majority of its assets or has approved, or not opposed, a tender or exchange offer for 50% or more of the corporation's outstanding stock, the stockholders of the corporation are benefited by the promotion of bidding contests. Section 203(b)(6) allows a bidder who announces a transaction subsequent to the public announcement of a management-approved transaction and prior to the completion or abandonment of the approved transaction to be free of the requirements of Section 203.

        Oregon also has enacted a control share statute that is contained in the Oregon Business Corporation Act. The Oregon Control Share Act provides that "control shares" of a corporation acquired in a control share acquisition have no voting rights except as granted by the shareholders of

129

the corporation. "Control shares" are shares which, when added to shares then owned or controlled by a shareholder, increase the shareholder's control of voting power above one of three thresholds:

        A majority of the votes cast by holders of shares entitled to vote, excluding shares voted or controlled by the acquiring person and officers and directors, must approve voting rights for shares acquired in a control share acquisition. No such approval, however, is required for gifts or other transactions not involving consideration, for a merger to which the corporation is a party, or other transactions described in the Oregon Control Share Act.

        Submission for shareholder consideration of a resolution to grant voting rights to control shares must be preceded by the filing with the corporation of a statement by the acquiring person providing certain specified information. If the acquiring person requests a special meeting of shareholders when it delivers its statement and submits an undertaking to pay the corporation's expenses, the corporation shall call a special meeting to consider solely the voting rights to be accorded the voting shares acquired in the control share acquisition, not later than 10 days from the date of receipt of the acquiring person's statement. Unless the acquiring person agrees otherwise in writing, the special meeting of shareholders shall be held no sooner than 30 days and no later than 50 days after receipt by the corporation of the acquiring person's statement. If no request for a special meeting of shareholders is made in the acquiring person's statement, the board of directors shall present to the next annual or special meeting of shareholders occurring more than 60 days after the filing of the acquiring person's statement, the voting rights to be accorded the voting shares acquired in the control share acquisition.

        Unless otherwise provided in a corporation's articles of incorporation or bylaws, if control shares acquired in a control share acquisition are accorded full voting rights and the acquiring person has acquired a majority of all voting power of the corporation, the shareholders of the corporation, other than the acquiring person, have dissenters' rights and shall be entitled to obtain the fair value of the holder's shares. "Fair value" means a value not less than the highest price paid per share by the acquiring person in the control share acquisition.

Liquidation

        Veeco and FEI.    Under both the Delaware General Corporation Law and the Oregon Business Corporation Act, in the event of a liquidation, dissolution or winding up of a corporation, after payment of any amounts owed to creditors, subject to preferences of any outstanding preferred stock, the remaining assets of the corporation will be divided equally, on a share for share basis, among the holders of common stock of the corporation.

Rights Plan

        Veeco.    Veeco and American Stock Transfer and Trust Company, as rights agent, entered into a rights agreement, dated as of March 13, 2001. Pursuant to the rights agreement, on March 13, 2001 Veeco's board of directors declared a dividend distribution of one right for each outstanding share of Veeco common stock to stockholders of record at the close of business on March 30, 2001. Each right entitled the registered holder to purchase from Veeco a unit consisting of one ten-thousandth of a share of Series A Junior Participating Preferred Stock, par value $0.01 per share, at a purchase price of $200 per unit.

130

        Subject to certain exceptions specified in the rights agreement, the rights are separate from the Veeco common stock and a distribution date will occur upon the earlier of:

        The rights are not exercisable until the distribution date and will expire on March 30, 2011, unless such date is extended or the rights are earlier redeemed or exchanged by Veeco.

        If a person acquires 15% or more of the outstanding shares of Veeco's common stock, except pursuant to an offer for all outstanding shares of common stock that the independent directors determine to be fair and not inadequate to, and to otherwise be in the best interests of Veeco and its stockholders, after receiving advice from one or more investment banking firms, then each holder of a right will have the right to receive, upon exercise, common stock (or, in certain circumstances, cash, property or other securities of Veeco) having a value equal to two times the exercise price of the right. All rights that are, or (under certain circumstances specified in the rights agreement) were beneficially owned by the person who acquired 15% or more of the outstanding shares of Veeco common stock become null and void.

        If, at any time following the date of public announcement that a person has acquired 15% or more of the outstanding shares of Veeco common stock:

then each holder of a right (except rights which have previously been voided as set forth above) shall thereafter have the right to receive, upon exercise, common stock of the acquiring company having a value equal to two times the exercise price of the right.

        At any time after a person acquires 15% or more of the outstanding shares of Veeco's common stock and prior to the acquisition by such person or group of fifty percent (50%) or more of the outstanding common stock, the Veeco board of directors may exchange the rights (other than rights owned by such person or group which have become void), in whole or in part, at an exchange ratio of one share of common stock, or one ten-thousandth of a share of preferred stock (or of a share of a class or series of Veeco's preferred stock having equivalent rights, preferences and privileges), per right (subject to adjustment).

        In certain circumstances, Veeco may redeem the rights in whole, but not in part, at a price of $0.01 per right (payable in cash, common stock or other consideration deemed appropriate by the Veeco board of directors). Immediately upon the action of the Veeco board of directors ordering redemption of the rights, the rights will terminate and the only right of the holders of rights will be to receive the $0.01 redemption price.

        FEI.    FEI does not have a shareholder rights plan in place.

        1.1    ANNUAL MEETING. The annual meeting of stockholders shall be held at a place and time determined by the board of directors (the "Board").

        1.2    SPECIAL MEETINGS. Special meetings of the stockholders may be called by resolution of the Board or by the president or chief executive officer and shall be called by the president, chief executive officer or secretary upon the written request (stating the purpose or purposes of the meeting) of a majority of the directors then in office or of the holders of 50% of the outstanding shares entitled to vote. Only business related to the purposes set forth in the notice of the meeting may be transacted at a special meeting.

        1.3    PLACE AND TIME OF MEETINGS. Meetings of the stockholders may be held in or outside Delaware at the place and time specified by the Board, the chief executive officer of the Corporation or the directors or stockholders requesting the meeting (as applicable).

        1.4    NOTICE OF MEETINGS; WAIVER OF NOTICE. Written notice of each meeting of stockholders shall be given to each stockholder entitled to vote at the meeting, except that (a) it shall not be necessary to give notice to any stockholder who submits a signed waiver of notice before or after the meeting, and (b) no notice of an adjourned meeting need be given except when required under Section 1.6 of these bylaws or by law. Each notice of a meeting shall be given, personally or by mail, not less than 10 nor more than 60 days before the meeting and shall state the time and place of the meeting, and unless it is the annual meeting, shall state at whose direction or request the meeting is called and the purposes for which it is called. If mailed, notice shall be considered given when mailed to a stockholder at his address on the Corporation's records. The attendance of any stockholder at a meeting, without protesting at the beginning of the meeting that the meeting is not lawfully called or convened, shall constitute a waiver of notice by him.

        1.5    NATURE OF BUSINESS AT MEETINGS OF STOCKHOLDERS. No business may be transacted at an annual or special meeting of stockholders, other than business that is either (a) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board (or any duly authorized committee thereof), (b) otherwise properly brought before the meeting by or at the direction of the Board (or any duly authorized committee thereof) or (c) otherwise properly brought before the meeting by any stockholder of the Corporation (i) who is a stockholder of record on the date of the giving of the notice provided for in this Section 1.5 and on the record date for the determination of stockholders entitled to vote at such meeting and (ii) who complies with the notice procedures set forth in this Section 1.5.

        In addition to any other applicable requirements, for business to be properly brought before an annual or special meeting by a stockholder, such stockholder must have given timely notice thereof in proper written form to the secretary of the Corporation.

        To be timely, a stockholder's notice to the secretary must be delivered to or mailed and received at the principal executive offices of the Corporation (a) in the case of an annual meeting, not less than ninety (90) days nor more than one hundred and twenty (120) days prior to the anniversary date of the immediately preceding annual meeting of stockholders; PROVIDED, HOWEVER, that in the event that the annual meeting is called for a date that is not within thirty (30) days before or after such anniversary date, notice by the stockholder in order to be timely must be so received not later than the close of business on the tenth (10th) day following the day on which such notice of the date of the annual meeting was mailed or such public disclosure of the date of the annual meeting was made,

A-66

whichever first occurs; and (b) in the case of a special meeting, not less than ninety (90) days nor more than one hundred and twenty (120) days prior to such special meeting.

        To be in proper written form, a stockholder's notice to the secretary must set forth as to each matter such stockholder proposes to bring before the meeting (i) a brief description of the business desired to be brought before the meeting and the reasons for conducting such business at the meeting, (ii) the name and record address of such stockholder, (iii) the class or series and number of shares of capital stock of the Corporation which are owned beneficially or of record by such stockholder, (iv) a description of all arrangements or understandings between such stockholder and any other person or persons (including their names) in connection with the proposal of such business by such stockholder and any material interest of such stockholder in such business and (v) a representation that such stockholder intends to appear in person or by proxy at the meeting to bring such business before the meeting.

        At the same time or prior to the submission of any stockholder proposal of business to be conducted at an annual or special meeting that, if approved, could not be implemented by the Corporation without notifying or obtaining the consent or approval of any federal, state, municipal or other regulatory body, the proponent stockholder or stockholders shall submit to the secretary of the Corporation an analysis, satisfactory to the Board, demonstrating that the proposal will have no material detrimental effect on the business and operations of the Corporation after making the requisite notices or obtaining the requisite consents or approvals and after giving effect to the potential responses thereto.

        No business shall be conducted at a meeting of stockholders except business brought before the meeting in accordance with the procedures set forth in this Section 1.5; PROVIDED, HOWEVER, that, once business has been properly brought before the meeting in accordance with such procedures, nothing in this Section 1.5 shall be deemed to preclude discussion by any stockholder of any such business. If the chairman of the meeting determines that business was not properly brought before the meeting in accordance with such procedures, the chairman shall declare to the meeting that the business was not properly brought before the meeting and such business shall not be transacted.

Such notice must be accompanied by a written consent of each proposed nominee to being named as a nominee and to serve as a director if elected.

        No person shall be eligible for election as a director of the Corporation unless nominated in accordance with the procedures set forth in this Section 2.2.

        VOTING AGREEMENT, dated as of July 11, 2002 (this "Agreement"), between Philips Business Electronics International B.V., a company incorporated under the laws of the Netherlands (the "Stockholder"), and Veeco Instruments Inc., a Delaware corporation (the "Company" and, collectively with the Stockholder, the "Parties").

        WHEREAS, the Company, Venice Acquisition Corp., an Oregon corporation ("Acquisition"), and Florence have entered into an Agreement and Plan of Merger, dated as of July 11, 2002 (the "Merger Agreement"), which provides that, among other things, on the terms and subject to the conditions set forth therein, Acquisition shall be merged with and into Florence (the "Merger"), and each share of Florence Stock will be converted into the right to receive 1.355 shares of common stock, $0.01 par value per share (the "Company Stock"), of the Company; and

        WHEREAS, the Stockholder and the Company have entered into an Investor Agreement, dated as of July 11, 2002 (the "Investor Agreement") and the Amendment Agreement, dated as of July 11, 2002 (the "Amendment Agreement"); and

("Philips") and each other direct and indirect subsidiary of Philips not to, take any action to solicit, initiate, encourage, induce or facilitate the making, submission or announcement of any FEI Acquisition Proposal, or engage in discussions or negotiations with any person or entity (other than with Florence and the Company or any of their Affiliates or Representatives) with respect to any FEI Acquisition Proposal, (other than any Superior FEI Proposal or related FEI Acquisition Transaction) or disclose any nonpublic information relating to Florence or any subsidiary of Florence.

        WHEREAS, Veeco Instruments Inc. ("Veeco"), Venice Acquisition Corp., an Oregon corporation and a wholly owned subsidiary of Veeco ("Acquisition"), and the Company have entered into an Agreement and Plan of Merger, dated as of July 11, 2002 (the "Merger Agreement"), which provides that, among other things, on the terms and subject to the conditions set forth therein, Acquisition shall be merged with and into the Company (the "Merger"), and each share of FEI Common Stock will be converted into the right to receive 1.355 shares of Veeco common stock, $0.01 par value per share (the "Veeco Stock");

        WHEREAS, each Veeco Stockholder owns the number of Existing Veeco Shares (as defined herein) set forth opposite such Veeco Stockholder's name on Schedule A hereto and the Veeco Stockholders collectively own in the aggregate 119,290 Existing Veeco Shares;

        WHEREAS, as a condition to the willingness of the Company to enter into the Merger Agreement, the Company has requested that the Veeco Stockholders enter into this Agreement.

        NOW, THEREFORE, to induce the Company to enter into, and in consideration of its entering into, the Merger Agreement, and in consideration of the mutual covenants and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties to this Agreement, intending to be legally bound, hereby agree as follows:

EXHIBIT A

PROXY

        Reference is hereby made to that certain Voting Agreement, dated as of July    , 2002 (the "Voting Agreement"), of which this Proxy (this "Proxy") forms a part. Capitalized terms used but not defined in this Proxy have the respective meanings ascribed to such terms in the Voting Agreement. This Proxy is being delivered by the undersigned Stockholder (the "Granting Stockholder") pursuant to Section 3.01(b) of the Voting Agreement.

        The undersigned Granting Stockholder hereby appoints FEI Company, an Oregon corporation ("FEI"), and each of FEI's officers and other designees (each such person or entity, a "Proxyholder") as the Granting Stockholder's attorney-in-fact and proxy pursuant to the provisions of Section 212 of the Delaware General Corporation Law, with full power of substitution, in the Granting Stockholder's name, place and stead, to vote and otherwise act (by written consent or otherwise) with respect to all of the Stockholder Veeco Shares which the Granting Stockholder is entitled to vote at any meeting of the stockholders of Veeco (whether annual or special and whether or not an adjourned or postponed meeting) or consent in lieu of any such meeting or otherwise FOR AND IN FAVOR OF the issuance of Veeco Stock in the Merger and approval of the Veeco Certificate of Incorporation Amendment; provided, however, that nothing set forth in this Proxy is intended or shall be construed to grant to any Proxyholder the right to vote or otherwise act (by written consent or otherwise) with respect to any Stockholder Veeco Shares with respect to any Superior Veeco Proposal or related Veeco Acquisition Transaction.

        The Granting Stockholder hereby revokes all other proxies and powers of attorney with respect to any Stockholder Veeco Shares that the Granting Stockholder may have heretofore granted, and no subsequent proxy or power of attorney shall be given or written consent executed (and if given or executed, shall not be effective) by the Granting Stockholder purporting to grant the specific voting powers specified herein. Any obligation of the Granting Stockholder under this Proxy shall be binding upon the successors and assigns of the Granting Stockholder other than the transferees under Section 3.03(d).

        THIS PROXY IS COUPLED WITH AN INTEREST AND IS IRREVOCABLE UNTIL THE EARLIEST TO OCCUR OF (I) THE TERMINATION OF THE MERGER AGREEMENT IN ACCORDANCE WITH ITS TERMS, (II) THE EFFECTIVE TIME OF THE MERGER, AND (III) THE EXECUTION AND DELIVERY BY ANY PARTY TO THE MERGER AGREEMENT OF ANY AMENDMENT THERETO WHICH WOULD CAUSE EACH SHARE OF FEI COMMON STOCK TO BE CONVERTED INTO THE RIGHT TO RECEIVE GREATER THAN 1.355 SHARES OF VEECO STOCK (AS ADJUSTED FOR ANY STOCK SPLITS, REVERSE STOCK SPLITS, STOCK DIVIDENDS OR SIMILAR EVENTS). THIS PROXY WILL AUTOMATICALLY TERMINATE AND WILL BE AUTOMATICALLY REVOKED, AND THE INTEREST WITH WHICH THIS PROXY IS COUPLED WILL BE AUTOMATICALLY EXTINGUISHED, UPON THE EARLIEST TO OCCUR OF THE EVENTS SPECIFIED IN THE PREVIOUS SENTENCE.

Members of the Board:

        You have asked us to advise you with respect to the fairness, from a financial point of view, to the holders of shares of common stock, no par value per share ("FEI Common Stock"), of FEI Company ("FEI"), other than Philips Business Electronics International B.V. ("Philips") and its affiliates, of the Exchange Ratio (as defined below) set forth in the Agreement and Plan of Merger, dated as of July 11, 2002 (the "Merger Agreement", by and among Veeco Instruments Inc. ("Veeco"), Veeco Acquisition Corp., a wholly owned subsidiary of Veeco ("Merger Sub"), and FEI. The Merger Agreement provides for, among other things, the merger of Merger Sub with and into FEI (the "Merger") pursuant to which FEI will become a wholly owned subsidiary of Veeco and each outstanding share of FEI Common Stock will be converted into the right to receive 1.355 (the "Exchange Ratio") shares of common stock, par value $0.01 per share ("Veeco Common Stock"), of Veeco.

        In arriving at our opinion, we have reviewed the Merger Agreement and certain other related agreements, as well as certain publicly available business and financial information relating to FEI and Veeco. We have also reviewed certain other information relating to FEI and Veeco, including financial forecasts, provided by or discussed with FEI and Veeco, and have met with the managements of FEI and Veeco to discuss the business and prospects of FEI and Veeco, respectively. We have also considered certain financial and stock market data of FEI and Veeco, and we have compared that data with similar data for other publicly held companies in businesses we deemed similar to those of FEI and Veeco, and we have considered, to the extent publicly available, the financial terms of certain other business combinations and other transactions which have recently been effected or announced. We also considered such other information, financial studies, analyses and investigations and financial, economic and market criteria which we deemed relevant.

        In connection with our review, we have not assumed any responsibility for independent verification of any of the foregoing information and have relied on such information being complete and accurate in all material respects. With respect to the publicly available financial forecasts that we have reviewed, the managements of FEI and Veeco have advised us, and we have assumed, that such forecasts represent reasonable estimates and judgments as to the future financial performance of FEI and Veeco, respectively. With respect to the non-publicly available financial forecasts that we have reviewed, the managements of FEI and Veeco have advised us, and we have assumed, that such forecasts represent the best currently available estimates and judgments of the managements of FEI and Veeco as to the future financial performance of FEI and Veeco, respectively. In addition, we have relied upon, without independent verification, the assessments of the managements of FEI and Veeco as to (i) their ability to retain key employees, (ii) the strategic benefits and potential cost savings (including the amount,

D-1

timing and achievability thereof) anticipated to result from the Merger, (iii) the existing technology, products and services of FEI and Veeco and the validity of, and risks associated with, the future technology, products and services of FEI and Veeco, and (iv) their ability to integrate the businesses of FEI and Veeco. The management of FEI has informed us, and we have assumed, that the Merger will be treated as a tax-free reorganization for federal income tax purposes. We also have assumed, with your consent, that in the course of obtaining necessary regulatory and third party approvals and consents for the Merger, no modification, delay, limitation, restriction or condition will be imposed that will have a material adverse effect on FEI or Veeco or the contemplated benefits of the Merger and that the Merger will be consummated in accordance with the terms of the Merger Agreement, without waiver, modification or amendment of any material term, condition or agreement therein. In addition, we have not been requested to make, and have not made, an independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of FEI or Veeco, nor have we been furnished with any such evaluations or appraisals. Our opinion is necessarily based upon information made available to us as of the date hereof, and upon financial, economic, market and other conditions as they exist and can be evaluated on the date hereof. We are not expressing any opinion as to what the value of Veeco Common Stock actually will be when issued to the holders of FEI Common Stock pursuant to the Merger or the prices at which shares of Veeco Common Stock will trade at any time. Our opinion does not address the relative merits of the Merger as compared to other business strategies that might be available to FEI, nor does it address the underlying business decision of FEI to proceed with the Merger. We were not requested to, and did not, solicit third party indications of interest in acquiring all or any part of FEI.

        We have acted as financial advisor to FEI in connection with the Merger and will receive a fee for our services, a significant portion of which is contingent upon the consummation of the Merger. We will also receive a fee for rendering this opinion. In the past, we and our affiliates have provided investment banking and financial services to FEI unrelated to the Merger for which we have received compensation, and we may, in the future, provide investment banking and financial services to Veeco for which we would expect to receive compensation. In the ordinary course of our business, we and our affiliates may actively trade the debt and equity securities of FEI and Veeco for our and such affiliates' own accounts and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.

        It is understood that this letter is for the information of the Board of Directors of FEI in connection with its consideration of the Merger and does not constitute a recommendation to any stockholder as to how such stockholder should vote or act on any matter relating to the Merger.

        Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio is fair, from a financial point of view, to the holders of FEI Common Stock, other than Philips and its affiliates.

[LETTERHEAD OF SALOMON SMITH BARNEY INC.]

July 11, 2002

The Board of Directors
Veeco Instruments Inc.
100 Sunnyside Blvd.
Woodbury, NY 11797

Members of the Board:

You have requested our opinion as to the fairness, from a financial point of view, to Veeco Instruments Inc. ("Veeco") of the Exchange Ratio (as defined below) as set forth in the Agreement and Plan of Merger, dated as of July 11, 2002 (the "Merger Agreement"), by and among Veeco, Venice Acquisition Corp., a wholly owned subsidiary of Veeco ("Merger Sub"), and FEI Company ("FEI"). As more fully described in the Merger Agreement, (i) Merger Sub will be merged with and into FEI (the "Merger") and (ii) each outstanding share of common stock, no par value per share, of FEI ("FEI Common Stock") will be converted into the right to receive 1.355 (the "Exchange Ratio") shares of common stock, par value $0.01 per share, of Veeco ("Veeco Common Stock").

In arriving at our opinion, we reviewed the Merger Agreement and held discussions with certain senior officers, directors and other representatives and advisors of Veeco and certain senior officers and other representatives and advisors of FEI concerning the businesses, operations and prospects of Veeco and FEI. We examined certain publicly available business and financial information relating to Veeco and FEI as well as certain financial forecasts and other information and data relating to Veeco and FEI, which were provided to or otherwise discussed with us by the respective managements of Veeco and FEI, including certain information relating to the potential strategic implications and operational benefits anticipated by the managements of Veeco and FEI to result from the Merger. 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 Veeco Common Stock and FEI Common Stock; historical and projected earnings and other operating data of Veeco and FEI; and the capitalization and financial condition of Veeco and FEI. We considered, to the extent publicly available, the financial terms of other transactions effected which we considered relevant in evaluating the Merger and 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 Veeco and FEI. We also evaluated the potential pro forma financial impact of the Merger on Veeco. In addition to the foregoing, we conducted such other analyses and examinations and considered such other financial, economic and market criteria as we deemed appropriate in arriving at our opinion.

In rendering our opinion, we have assumed and relied, without independent verification, upon the accuracy and completeness of all financial and other information and data publicly available or furnished to or otherwise reviewed by or discussed with us. With respect to the financial forecasts and other information and data relating to Veeco and FEI provided to or otherwise discussed with us, we have been advised by the respective managements of Veeco and FEI 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 Veeco and FEI as to the future financial performance of Veeco and FEI and the potential strategic implications and operational benefits (including the amount, timing and achievability thereof) anticipated to result from the Merger. We have assumed, with your consent, that 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 and consents for the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on Veeco or FEI or the contemplated benefits of the Merger. 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 Veeco and FEI. We are not expressing any opinion as to what the value of Veeco Common Stock actually will be when issued in the Merger or the prices at which Veeco Common Stock will trade or otherwise be transferable 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 Veeco or FEI, nor have we made any physical inspection of the properties or assets of Veeco or FEI. Our opinion does not address the relative merits of the Merger as compared to any alternative business strategies that might exist for Veeco or the effect of any other transaction in which Veeco might engage. Our opinion is necessarily based upon information available to us, and financial, stock market and other conditions and circumstances existing and disclosed to us, as of the date hereof.

Salomon Smith Barney Inc. has acted as financial advisor to Veeco in connection with the proposed Merger and will receive a fee for such services, a significant portion of which is contingent upon the consummation of the Merger. We also will receive a fee upon the delivery of this opinion. We and our affiliates in the past have provided services to Veeco unrelated to the proposed Merger, for which services we and our affiliates have received compensation. In the ordinary course of our business, we and our affiliates may actively trade or hold the securities of Veeco and FEI 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 Veeco, FEI and their respective affiliates.

Our advisory services and the opinion expressed herein are provided for the information of the Board of Directors of Veeco 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 the proposed Merger or as to any other matters relating to the 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 Veeco.

Very truly yours,

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

        Section 145 of the Delaware General Corporation Law provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party 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 the corporation) by reason of the fact that the person 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, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person's conduct was unlawful. Section 145 further provides that a Delaware corporation similarly may indemnify any such person serving in any such capacity who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor, against expenses (including attorneys' fees) actually and reasonably incurred in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of Chancery or such other court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

        Article 9 of Veeco's Amended and Restated Certificate of Incorporation entitles officers and directors of Veeco to indemnification to the fullest extent permitted by Section 145 of the DGCL, as the same may be supplemented from time to time.

        Section 102(b)(7) of the DGCL permits a corporation to include in its certificate of incorporation a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to the corporation or its stockholder, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (relating to unlawful payment of dividends and unlawful stock purchase and redemption) or (iv) for any transaction from which the director derived an improper personal benefit.

        Veeco's Amended and Restated Certificate of Incorporation provides that its directors shall not be liable to Veeco or its stockholders for monetary damages for breach of fiduciary duty as a director except to the extent that exculpation from liabilities is not permitted under the DGCL as in effect at the time such liability is determined. Such Amended and Restated Certificate of Incorporation further provides that Veeco shall indemnify its directors and officers to the fullest extent permitted by the DGCL.

        Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling any registrant pursuant to the foregoing provisions, the registrant has been informed 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.

Item 22. Undertakings.

        (a)  The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 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.

        (b)  The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus that 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.

        (c)  The registrant undertakes that every prospectus: (i) that is filed pursuant to paragraph (b) immediately preceding, or (ii) that purports to meeting the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a 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 of 1933, 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.

        (d)  Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing

II-4

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 of 1933 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 of 1933 and will be governed by the final adjudication of such issue.

        (e)  The undersigned registrant hereby undertakes that:

        (f)    The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 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.

        (g)  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.
