PROXY STATEMENT
FISCAL YEAR END 2008 ANNUAL MEETING OF SHAREHOLDERS
 
 
F5 Networks, Inc. (the “Company”) is furnishing this Proxy Statement and the enclosed proxy in connection with the solicitation of proxies by the Board of Directors of the Company for use at the annual meeting of shareholders to be held on March 12, 2009, at 11:00 a.m., Pacific time at F5 Networks, Inc., 333 Elliott Avenue West, Seattle, Washington 98119, and at any adjournments thereof (the “Annual Meeting”). These materials are being mailed to shareholders on or about January 20, 2009. The Company’s principal executive offices are located at 401 Elliott Avenue West, Seattle, Washington 98119. The Company’s telephone number at that location is 206-272-5555.
 
Only holders of the Company’s common stock, no par value (the “Common Stock”), as of the close of business on January 8, 2009 (the “Record Date”) are entitled to vote at the Annual Meeting. As of the Record Date, there were 79,020,081 shares of Common Stock outstanding.
 
A majority of the outstanding shares of Common Stock entitled to vote at the Annual Meeting must be present in person or by proxy in order for there to be a quorum at the meeting. Shareholders of record who are present at the meeting in person or by proxy and who abstain from voting, including brokers holding customers’ shares of record who cause abstentions to be recorded at the meeting, will be included in the number of shareholders present at the meeting for purposes of determining whether a quorum is present.
 
Each shareholder of record is entitled to one vote at the Annual Meeting for each share of Common Stock held by the shareholder on the Record Date. Shareholders may vote their shares by using the enclosed proxy card, over the Internet or by phone. If a proxy is received that does not specify a vote or an abstention, the shares represented by that proxy will be voted (i) FOR the nominee to the Board of Directors listed in this Proxy Statement; (ii) FOR the amendment to the 2005 Plan; (iii) FOR the amendment to the ESPP; (iv) FOR the ratification of the selection of PricewaterhouseCoopers LLP as the Company’s independent auditor for the fiscal year ending September 30, 2009; and (v) in accordance with the discretion of the named proxies on any other matters properly brought before the Annual Meeting. The Company is not aware, as of the date hereof, of any matters to be voted upon at the Annual Meeting other than those stated in this Proxy Statement and the accompanying Notice of Annual Meeting of Shareholders. If any other matters are properly brought before the Annual Meeting, the enclosed proxy card and proxies submitted by telephone or over the Internet give discretionary authority to the person named as proxy to vote the shares represented by the proxy in his discretion.
 
Under Washington law and the Company’s Second Amended and Restated Articles of Incorporation (the “Articles”) and Third Amended and Restated Bylaws (the “Bylaws”), if a quorum exists at the meeting, a nominee for director in an uncontested election will be elected by the vote of the majority of votes cast. In addition, if a quorum exists at the meeting, approval of all other matters that properly come before the Annual Meeting requires that the votes cast in favor of such actions exceed the votes cast against such actions. Abstentions and “broker non-votes” (shares held by a broker or nominee that does not have the authority, either express or discretionary, to vote on a particular matter) will have no impact on the election of directors or the other proposals at the meeting since they have not been cast in favor of or against any nominee or a proposal.
 
A shareholder may revoke a proxy at any time before it is voted at the Annual Meeting by (a) delivering a proxy revocation or another proxy bearing a later date to the Corporate Secretary of the Company at 401 Elliott Avenue West, Seattle, Washington 98119 before or at the Annual Meeting or (b) attending the Annual Meeting and voting in person. Attendance at the Annual Meeting will not revoke a proxy unless the shareholder actually votes in person at the meeting.

The Board of Directors of the Company is soliciting the proxies accompanying this Proxy Statement. The Company will pay all of the costs of this proxy solicitation. However, you will need to obtain your own Internet access if you choose to access the proxy materials and/or vote over the Internet. In addition to mail solicitation, officers, directors, and employees of the Company may solicit proxies personally or by telephone, without receiving additional compensation. The Company has retained Advantage Proxy to assist in connection with the solicitation of proxies in connection with the Annual Meeting. The Company will pay Advantage Proxy customary fees, which are expected to be $5,750 plus expenses. The Company, if requested, will pay brokers, banks, and other fiduciaries that hold shares of Common Stock for beneficial owners for their reasonable out-of-pocket expenses of forwarding these materials to shareholders.
 
BOARD OF DIRECTORS
 
The Board of Directors of the Company consists of six directors divided into three classes. Currently, the Class I director is Karl D. Guelich; the Class II directors are Deborah L. Bevier, Alan J. Higginson and John McAdam; and the Class III directors are A. Gary Ames and Scott Thompson. At the Annual Meeting, the shareholders will vote on the election of one Class I director to serve for a three-year term until the annual meeting of shareholders for fiscal year end 2011 and until the director’s successor is elected and qualified. The Class II directors will hold office until the Company’s annual meeting for fiscal year end 2009 and the Class III directors will hold office until the Company’s annual meeting for fiscal year end 2010. All directors will hold office until the annual meeting of shareholders at which their terms expire and the election and qualification of their successors.
 
The Board of Directors has nominated Karl D. Guelich for re-election to the Board of Directors as a Class I director at the Annual Meeting. The nominee has consented to serve as a director of the Company if elected. If the nominee declines to serve or becomes unavailable for any reason, or if a vacancy occurs before the election (although we know of no reason to anticipate that this will occur), the proxies may be voted for a substitute nominee as the Company may designate. The Board of Directors is currently searching for an additional nominee to serve as a Class I director to fill the vacancy resulting from the death of Keith Grinstein on September 27, 2008. The Board of Directors does not anticipate that it will complete this search until after the Annual Meeting. If the Board of Directors identifies an additional director after the Annual Meeting, pursuant to the Bylaws the Board of Directors can appoint such person to serve as a Class I director until the Company’s annual meeting for fiscal year end 2009, at which time such Class I director would stand for re-election to serve for the remainder of the term applicable to the Class I directors (until the annual meeting of shareholders for fiscal year end 2011 and until his or her successor is elected and qualified).
 
Director Independence
 
The Nasdaq Marketplace Rules require that a majority of the Company’s directors be “independent,” as defined by Nasdaq Marketplace Rules 4200(a)(15) and 4350(c) and determined by the Board of Directors. The Board of Directors consults with the Company’s legal counsel to ensure that the Board’s determinations are consistent with all relevant securities and other laws and regulations regarding the definition of “independent.” After a review of any relevant transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent auditors, the Board of Directors has determined that the following directors and nominee are independent: A. Gary Ames, Deborah L. Bevier, Karl D. Guelich, Alan J. Higginson and Scott Thompson. John McAdam is not considered independent because he is the Company’s President and Chief Executive Officer.

CORPORATE GOVERNANCE
 
Committees of the Board of Directors
 
The Board of Directors has standing Audit, Compensation and Nominating and Corporate Governance Committees (collectively, the “Standing Committees”). Each of the Standing Committees has a charter, copies of which are available on our website at www.f5.com under the “About F5 — Investor Relations — Corporate Governance” section.
 
Audit Committee.  As described more fully in the Audit Committee charter, the functions of the Audit Committee are to select, evaluate and, if necessary, replace the Company’s independent registered public accounting firm, to review and approve the planned scope, proposed fee arrangements and results of the annual audit, approve any proposed non-audit services to be provided by the independent registered public accounting firm, oversee the adequacy of accounting and financial controls, review the independence of the auditors, and oversee the Company’s financial reporting process on behalf of the Board of Directors. The Audit Committee members are Messrs. Guelich (chairman) and Thompson, and Ms. Bevier. The Board of Directors has determined that Mr. Guelich is an “audit committee financial expert” as defined in Item 407 of Regulation S-K. Each current member of the Audit Committee is, and each member of the Audit Committee during fiscal year 2008 was, an independent director as defined by the Nasdaq Marketplace Rules (as independence is currently defined in Rules 4200(a)(15) and 4350(c) therein).
 
Compensation Committee.  The Compensation Committee conducts an annual review to determine whether the Company’s executive compensation program is meeting the goals and objectives set by the Board of Directors. The Compensation Committee recommends for approval by the Board of Directors the compensation for the Chief Executive Officer and directors, including salaries, incentive compensation levels and stock awards, and reviews and approves compensation proposals made by the Chief Executive Officer for the other executive officers. The Compensation Committee members are Messrs. Higginson (chairman) and Ames, and Ms. Bevier. Each current member of the Compensation Committee is, and each member of the Compensation Committee during fiscal 2008 was, an independent director as defined by the Nasdaq Marketplace Rules. In fiscal year 2008, the Compensation Committee retained an outside independent compensation consultant, Towers Perrin, to advise the Compensation Committee on executive compensation issues. Towers Perrin provides the Compensation Committee peer and survey group cash and equity compensation data, including 50th and 75th percentile base salary, total cash, long-term incentive and total direct compensation data. For additional information about the Compensation Committee and the information provided by Towers Perrin to the Compensation Committee, see the description of the Compensation Committee’s activities in the Executive Compensation — Compensation Discussion and Analysis section.
 
Nominating and Corporate Governance Committee.  The Nominating and Corporate Governance Committee’s function is to identify new potential board members, recommend board nominees, evaluate the board’s performance, and provide oversight of corporate governance and ethical conduct. The Nominating and Governance Committee members are Messrs. Ames (chairman), Guelich, Higginson and Thompson. Each current member of the Nominating and Governance Committee is, and each member of this committee during fiscal year end 2008 was, an independent director as defined by the Nasdaq Marketplace Rules.

During fiscal year 2008, the Compensation Committee consisted of Messrs. Grinstein (who served as chairman until his death on September 27, 2008), Higginson (chairman) and Ames, and Ms. Bevier. None of the Company’s executive officers served as a member of the board of directors or compensation committee of any entity that has had one or more executive officers that served as a member of the Company’s Board of Directors or Compensation Committee.
 
Related Person Transactions Policy and Procedures
 
As set forth in the charter of the Audit Committee of the Board of Directors, any related person transaction involving a Company director or executive officer must be reviewed and approved by the Audit

Table of Contents

Committee. Any member of the Audit Committee who is a related person with respect to a transaction under review may not participate in the deliberations or vote on the approval or ratification of the transaction. Related persons include any director or executive officer, certain shareholders and any of their “immediate family members” (as defined by SEC regulations). To identify any related person transaction, the Company requires each director and executive officer to complete a questionnaire each year requiring disclosure of any prior or proposed transaction in which the director, executive officer or any immediate family member might have an interest. Each director and executive officer is directed to notify the Company’s Senior Vice President and General Counsel of any such transaction that arises during the year and the Company’s Chief Accounting Officer reports to the Audit Committee on a quarterly basis regarding any potential related person transaction. In addition, the Board of Directors determines on an annual basis which directors meet the definition of independent director under the Nasdaq Marketplace Rules and reviews any director relationship that would potentially interfere with his or her exercise of independent judgment in carrying out the responsibilities of a director. A copy of the Company’s “Policy and Procedure for Approving Related-Person Transactions” is available on our website at www.f5.com under the “About F5 — Investor Relations — Corporate Governance” section.
 
Certain Relationships and Related Person Transactions
 
The Company’s Articles limit the liability of the Company’s directors for monetary damages arising from their conduct as directors, except to the extent otherwise required by the Articles and the Washington Business Corporation Act. The Articles also provide that the Company may indemnify its directors and officers to the fullest extent permitted by Washington law, including in circumstances in which indemnification is otherwise discretionary under Washington law. The Company has entered into indemnification agreements with the Company’s directors and executive officers for the indemnification of, and advancement of expenses to, these persons to the fullest extent permitted by law. The Company also intends to enter into these agreements with the Company’s future directors and certain future officers.
 
Pursuant to these indemnification agreements, the Company has advanced or indemnified certain current and former directors and officers for fees and expenses incurred by them in connection with the Special Committee’s review of the Company’s stock option practices, including a review of our underlying stock option documentation and procedures, and the previously disclosed restatement of the Company’s financial statements, legal proceedings and other matters related to the Company’s stock option practices, all as described in the Company’s Annual Report to Shareholders on Form 10-K for the fiscal year ended September 30, 2008, which is being mailed to shareholders of the Company with this proxy statement, and online at www.proxyvote.com and www.f5.com under the “About F5 — Investor Relations — Corporate Governance” section.
 
Meetings of the Board of Directors and Standing Committees; Attendance at Annual Meetings
 
The Company’s Board of Directors met or acted by unanimous written consent 7 times during fiscal 2008. The Audit Committee met 8 times and the Compensation Committee met or acted by unanimous written consent 11 times. During fiscal 2008, the Nominating and Corporate Governance Committee met 4 times. The outside directors met 4 times during fiscal 2008, with no members of management present. Each member of the Board of Directors attended 75% or more of the Board meetings during fiscal 2008. Each member of the Board of Directors who served on one or more of the Standing Committees attended at least 75% of the applicable committee meetings during fiscal year 2008. All directors are also expected to be present at the Company’s annual meetings of shareholders. All directors attended the Company’s fiscal year 2007 annual meeting.
 
Director Nomination
 
Criteria for Nomination to the Board of Directors.  The Nominating and Corporate Governance Committee (the “Nominating Committee”) considers the appropriate balance of experience, skills and characteristics required of the Board of Directors, and seeks to ensure that at least a majority of the directors are independent under the Nasdaq Marketplace Rules, that members of the Company’s Audit Committee meet

Table of Contents

the financial literacy requirements under the Nasdaq Marketplace Rules and that at least one of them qualifies as an “audit committee financial expert” under the rules of the Securities and Exchange Commission. Nominees for director are selected on the basis of their depth and breadth of experience, integrity, the ability to work effectively as part of a team, understanding of the Company’s business environment, and willingness to devote adequate time to Board duties.
 
Shareholders Proposals for Nominees.  The Nominating Committee will consider written proposals from shareholders for nominees for director. Any such nominations should be submitted to the Nominating Committee c/o the Secretary of the Company and should include the following information: (a) all information relating to such nominee that is required to be disclosed pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected); (b) the name(s) and address(es) of the shareholders(s) making the nomination and the number of shares of Common Stock that are owned beneficially and of record by such shareholders(s); and (c) appropriate biographical information and a statement as to the qualification of the nominee. Such nominations should be submitted in the time frame described in the Bylaws of the Company and under the caption “Shareholder Proposals for the Annual Meeting for Fiscal Year End 2009” below.
 
Process for Identifying and Evaluating Nominees.  The process for identifying and evaluating nominees for the Board of Directors is initiated by conducting an assessment of critical Company and Board of Directors needs, based on the present and future strategic objectives of the Company and the specific skills required for the Board as a whole and for each Board committee. A third-party search firm may be used by the Nominating Committee to identify qualified candidates. These candidates are evaluated by the Nominating Committee by reviewing the candidates’ biographical information and qualification and checking the candidates’ references. Serious candidates meet with all members of the Board of Directors, and as many of the Company’s executive officers as practical. Using the input from such interviews and the information obtained by the Nominating Committee, the full Board of Directors determines whether to appoint a candidate to the Board of Directors. The Nominating Committee expects that a similar process will be used to evaluate nominees recommended by shareholders. However, to date, the Company has not received any shareholder’s proposal to nominate a director.
 
Mr. Thompson, who joined the Board of Directors in January 2008, was recommended by a third-party search firm retained by the Nominating Committee at the expense of the Company. The third-party search firm was provided guidance as to the particular skills, experience and other characteristics the Nominating Committee was seeking in potential candidates. The third-party search firm identified a number of potential candidates, including Mr. Thompson, and prepared background materials on these candidates which were provided to the members of the Nominating Committee for their review. The third-party search firm interviewed those candidates the Nominating Committee determined merited further consideration, and assisted in arranging interviews of selected candidates with members of the Nominating Committee, other members of the Board of Directors, and certain of the Company’s executive officers. The third-party search firm also completed reference checks on the candidates.
 
The nominee to the Board of Directors described in this Proxy Statement was approved by at least a majority of Company’s independent directors.
 
Communications with Directors
 
Shareholders who wish to communicate with our Directors may do so by contacting them c/o Corporate Secretary, F5 Networks, Inc., 401 Elliott Avenue West, Seattle, Washington 98119. As set forth in the Company’s Corporate Governance Guidelines, a copy of which may be found under the “About F5 — Investor Relations — Corporate Governance” section of our website, www.f5.com, these communications will be forwarded by the Corporate Secretary to a Board member, Board committee or the full Board of Directors as appropriate.
 
Code of Ethics for Senior Financial Officers
 
We have adopted a Code of Ethics that applies to all of our senior financial officers, including our Chief Executive Officer, Chief Finance Officer and Chief Accounting Officer. The Code of Ethics is posted on the

The complaints generally allege that certain of our current and former directors and officers, including, in general, each of our current outside directors (other than Deborah L. Bevier and Scott Thompson who joined our Board of Directors in July 2006 and January 2008, respectively) breached their fiduciary duties to the Company by engaging in alleged wrongful conduct concerning the manipulation of certain stock option grant dates. The Company is named solely as a nominal defendant against whom the plaintiffs seek no recovery. Our combined motion to consolidate and stay the State Court Derivative Litigation was granted in a court order dated April 3, 2007. Our motion to dismiss the consolidated Federal Court Derivative Litigation based on plaintiffs’ failure to make demand on our Board of Directors prior to filing suit was granted in a court order dated August 6, 2007 with leave to amend the allegations in plaintiffs’ complaint. Plaintiffs filed an amended consolidated federal derivative action complaint on September 14, 2007. We filed a motion to dismiss the amended complaint based on plaintiff’s failure to make demand on our Board of Directors prior to filing suit. On July 3, 2008, before ruling on our pending dismissal motion, the federal court entered an order certifying certain issues of Washington state law to the Washington Supreme Court for resolution. Briefing the Washington Supreme Court on the certified issues began on September 15, 2008 and the hearing is currently set for March 24, 2009. The Federal Court Derivative Litigation is stayed pending resolution of the certification proceeding. We intend to continue to vigorously pursue dismissal of the derivative actions. Due to the inherent uncertainties of litigation, we are unable to predict the outcome of these matters at this time.

EXECUTIVE COMPENSATION
 
Compensation Discussion and Analysis
 
Compensation Philosophy
 
The Company’s philosophy concerning compensation for executive officers is to directly link their compensation to and to reward executive officers for continuous improvements in the Company’s financial performance and the creation of shareholder value. The key elements of this philosophy are as follows:
 
  •  provide a competitive total compensation package that enables the Company to attract, motivate, reward and retain executive officers who contribute to the Company’s success;
 
  •  provide incentive compensation that is linked to the performance of the Company and aligns the interests of executive officers with the long-term interests of shareholders; and
 
  •  establish incentives that relate to the Company’s quarterly, annual and long-term business strategies and objectives.
 
The Compensation Committee believes that the Company’s executive compensation should also reflect each executive officer’s qualifications, experience, role and personal performance, and the Company’s performance achievements.
 
Objectives of Our Executive Compensation Program
 
The objectives of our executive compensation program are to correlate executive compensation with the Company’s business objectives and performance and the creation of shareholder value, and to enable the Company to attract, retain and reward key executive officers who contribute to its long-term success.
 
Elements of Our Compensation Program
 
The three primary components of our executive compensation program are; (i) base salary, (ii) incentive compensation in the form of cash bonuses, and (iii) equity compensation.
 
Base Salary.
 
Base salary is the guaranteed element of employees’ annual cash compensation. Executive officers’ base salaries are set at levels that reflect their specific job responsibilities, experience, qualifications, job performance and potential contributions, market data from two salary surveys covering technology companies in comparable areas (“Survey Companies”) and compensation paid to comparable executives as set forth in proxy statements for a peer group of 29 companies (“Peer Group Companies”) developed by an outside independent compensation consultant (See “Factors Considered — Benchmarking”). Base salaries are reviewed and adjusted annually and may also be adjusted from time to time in recognition of individual performance, promotions and marketplace competitiveness. The base salaries of the executive officers, including Mr. McAdam, are generally set at or near the 50th percentile range of base compensation for comparable executive officers in the Peer Group Companies.
 
Incentive Compensation.
 
The Compensation Committee believes that incentives based on attaining or exceeding established financial targets, properly align the interests of the executive officers with the interests of the shareholders. All of our executive officers participate in the Incentive Compensation Plan for Executive Officers (“Incentive Plan”). The Incentive Plan is a cash incentive bonus plan, with each executive officer assigned a target bonus amount expressed as a percentage of such executive officer’s base salary, ranging from 30% to 80%. The Compensation Committee determines each of these target bonus percentages based on its assessment of the impact each position had on the Company’s financial performance and compensation data from the Survey Companies and Peer Group Companies provided by the outside consultant. The total direct cash compensation (base salary plus the target bonus) of the executive officers, including Mr. McAdam, are generally set at or

Table of Contents

near the 50th percentile range of total direct cash compensation for comparable executive officers at the Survey Companies and the Peer Group Companies.
 
If earned, the cash incentive bonus is paid quarterly. 50% of the cash incentive bonus is based on the Company achieving target revenue for the quarter and 50% is based on the Company achieving target adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) for the quarter. Each such target is determined by the Compensation Committee. See footnote (3) of the Grants of Plan-Based Awards Table for Fiscal 2008 for information regarding the targets for fiscal year 2008. No cash incentive bonus will be paid for results less than 80% of an applicable target. The cash incentive bonus is paid on a linear basis above 80% of the targeted goals. Results for both targets must equal or exceed 100% for the total cash incentive bonus to be paid at 100% or more.
 
The Compensation Committee retains some discretion in the administration of the Incentive Plan. In calculating the percentage of target EBITDA achieved for the fourth quarter of fiscal year 2008, the Compensation Committee determined it was appropriate to exclude from this calculation the impact of a non-recurring loss in the amount of $5.3 million related to the Company’s consolidation and subleasing of facilities in Seattle and Bellevue, Washington, as this charge did not arise from or otherwise reflect the Company’s operating results in fiscal year 2008 and allowed the Company to generate subleasing revenue while retaining access to these facilities to accommodate the Company’s future growth in headcount. In fiscal year 2008, the Company achieved 98.9% of the annual revenue target and 97.5% of the annual adjusted EBITDA target. As a result, the executive officers earned 98.2% of their target cash incentive bonus in fiscal year 2008. The Compensation Committee believes that the cash incentive bonuses paid to the executive officers for performance in 2008 were merited based on the Company’s outstanding operating results as compared to the targets and the Company’s continued growth in market share. The Company increased total revenue in fiscal year 2008 by 24% as compared to fiscal year 2007, while continuing to maintain solid gross and operating margins. The fourth quarter of fiscal year 2008 was the Company’s 23rd consecutive quarter of sequential revenue growth. The Company generated record cash flow of $194 million and ended fiscal year 2008 with $451 million in cash and investments, after completing the purchase of Acopia Networks, Inc. and the repurchase of approximately $200 million of the Company’s common stock. During fiscal year 2008, the Company introduced a number of new products and saw customer satisfaction levels increase to record levels in all regions.
 
Equity Compensation.
 
The Compensation Committee believes that equity ownership aligns the interests of executive officers with those of the shareholders and provides significant motivation to executive officers to maximize value for the Company’s shareholders. In accordance with this belief, the Compensation Committee periodically approves grants of equity compensation under the Company’s equity incentive plan. The amounts of these grants are based on the relative position and responsibilities of each executive officer, previous and expected contributions of each officer to the Company’s success, equity compensation data from Survey Companies and Peer Group Companies provided by the outside consultant, previous grants to each officer, and recruitment and retention considerations. The types of awards include stock options and restricted stock units (“RSUs”). The value of equity compensation grants to each of the executive officers, including Mr. McAdam, is generally set between the 50th and 75th percentile range of the value of the most recent long-term incentive compensation grants to comparable executive officers in the Survey Companies and Peer Group Companies.
 
In January 2007, the Board approved and adopted a “Policy Regarding the Granting of Equity-Based Compensation Awards,” a copy of which may be found under the “About F5 — Investor Relations — Corporate Governance” section of the Company’s website, www.f5.com. This Policy provides that the Compensation Committee or the Board of Directors, as applicable, shall approve equity awards to existing employees and service providers (other than newly-promoted individuals and non-employee directors) on an annual basis on August 1 (or, if such day is not a business day, on the following business day). These annual equity awards vest in quarterly increments over a two year period. Equity awards to newly-hired employees and service providers (other than non-employee directors) and to newly-promoted individuals shall be approved on a quarterly basis on February 1, May 1, August 1 and November 1 (or, if such day is not a business day, on the following business day). These new-hire and promotion grants generally vest over a 4 year

Table of Contents

period, with 25% vesting on the first anniversary of the award and the balance vesting in equal quarterly increments over the following 3 years. The Compensation Committee or the Board of Directors, as applicable, may approve equity awards outside of the new hire grant date to select individuals in the event of extraordinary circumstances. Prior to each annual meeting of shareholders, the Compensation Committee reviews and recommends to the Board of Directors for approval the amount and terms of any equity awards to be granted to non-employee directors. The Board of Directors approves all equity awards to be granted to non-employee directors on the date of the annual meeting of shareholders.
 
Since December 2006, the Board and Compensation Committee have included a performance-based component in the annual equity awards granted to the executive officers. The vesting of 50% of each annual equity award to the executive officers will be subject to the Company achieving specified percentage increases in total revenue over the two year period following the awards (25% in the first four quarters and 25% in the second four quarters following the awards). The Compensation Committee sets these revenue targets on an annual basis. The Compensation Committee reviews and evaluates revenue projections proposed by management and considers industry, competitive and economic trends in setting these targets. The Compensation Committee believes that revenue growth is currently the most appropriate measure for the performance-based equity awards as the Company’s ability to consistently grow revenue is an important element in maintaining and growing shareholder value and furthers the shared interests of the Company’s executive officers and shareholders. The focus on revenue growth is balanced by the EBITDA targets in the Incentive Plan discussed above, intended to ensure the Company maintains its gross margin and operating margin targets while growing its revenue base. The performance-based equity awards approved in fiscal 2008 provide the Named Executive Officers (as identified in the Summary Compensation Table for Fiscal 2008 below) an opportunity to receive additional RSUs if the performance target is exceeded and further provides that a portion of the award will be forfeited if the performance target is not achieved. See footnote (4) of the Grants of Plan-Based Awards Table in Fiscal 2008 for additional information regarding the performance-based equity compensation program approved in fiscal year 2008. In accordance with the 2005 Plan, a Named Executive Officer must be employed by the Company or its affiliates on each vesting date in order to receive the shares of common stock issuable upon such vesting date.
 
Pursuant to the Company’s “Insider Trading Policy,” a copy of which may be found under the “About F5 — Investor Relations — Corporate Governance” section of our website, www.f5.com, the Company considers it improper and inappropriate for any employee, officer or director of the Company to engage in short-term or speculative transactions in the Company’s securities. The policy specifically prohibits directors, officers and other employees, and their family members, from engaging in short sales of the Company’s securities, transactions in puts, calls or other derivative securities on an exchange or in any other organized market, and certain hedging transactions related to the Company’s securities. In addition, directors, officers and other employees are prohibited, except under certain limited exceptions, from holding Company securities in a margin account or pledging Company securities as collateral for a loan.
 
Other Benefits and Perquisites.
 
The Company’s executive officers participate in broad-based benefit plans that are available to other employees. With the exception of an internet service stipend, the Company does not currently provide additional material perquisites for its executive officers.
 
How Each Element Fits Into our Overall Compensation Objectives and Affects Other Elements of Compensation
 
Consistent with our philosophy that a significant amount of the executive officers’ compensation should be directly linked to the performance of the Company and align the interests of executive officers with the long-term interests of shareholders, a majority of the executives’ compensation is based on the Company achieving certain performance and financial targets. We do not have an exact formula for allocating between cash and equity compensation, but target total direct cash compensation (base salary plus the target bonus) of the executive officers is at or near the 50th percentile range of total cash compensation for comparable

Table of Contents

executive officers in the Peer Group Companies, and total direct compensation (cash and equity compensation) is between the 50th and 75th percentiles.
 
Impact of Accounting and Tax Treatments of a Particular Form of Compensation
 
The accounting and tax treatment of the elements of our compensation program is one factor considered in the design of the compensation program. Under Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code” or “Internal Revenue Code”), the federal income tax deduction for certain types of compensation paid to the chief executive officer and the three other most highly compensated executive officers of publicly held companies (other than the chief executive officer and principal financial officer) is limited to $1 million per officer per fiscal year unless such compensation meets certain requirements. The Compensation Committee is aware of this limitation and has decided that it is not appropriate at this time to limit the Company’s discretion to design the compensation packages payable to the Company’s executive officers to comply with these deductibility guidelines.
 
Factors Considered — Benchmarking
 
The Compensation Committee conducts an annual review of the executive compensation program and utilizes peer and survey group data to help set proper compensation levels. For fiscal year 2008, the Compensation Committee retained an outside independent compensation consultant, Towers Perrin, to assist it in this review and to conduct a competitive review of the total direct compensation (cash and equity compensation) for the Company’s executive officers. The Compensation Committee instructed Towers Perrin to collect base salary, total cash, long-term incentive, and total direct compensation data and to analyze and compare on a pay rank and position basis our executive officers’ compensation with the compensation paid to comparable executives as set forth in proxy statements for the Peer Group Companies developed by Towers Perrin and approved by the Compensation Committee. The following is a list of these Peer Group Companies:
 
         
ADC Telecommunications Inc.
  Emulex Corp.   Quest Software
ADTRAN Inc.
  Finisar Corp.   Red Hat Inc.
Avocent Corp.

Role of Executive Officers in Determining Executive Compensation
 
The Compensation Committee annually assesses the performance of, and recommends to the full Board of Directors base salary and incentive compensation for the Company’s President and Chief Executive Officer. The Company’s President and Chief Executive Officer recommends to the Compensation Committee annual base salary and incentive compensation adjustments for the other executive officers.
 
Employment Contracts and Change-in-Control Arrangements
 
There are currently no written employment contracts with any of the Named Executive Officers. Each such officer is an “at-will” employee, and his employment may be terminated anytime with or without cause. The RSU and option grant agreements issued to our Named Executive Officers provide that upon certain changes in control of the Company the vesting of outstanding and unvested RSUs and options will accelerate and such RSUs and options will become fully vested. We believe that such change-in-control provisions provide an additional tool for attracting and retaining key executive officers.

(2) Represents the cash incentive bonus for fiscal year 2008 awarded under the Incentive Plan. The Compensation Committee approved for recommendation to the Board of Directors the fiscal year 2008 target bonus amount for Mr. McAdam and approved the fiscal year 2008 target bonus amounts for Messrs. Rodriguez, Triebes, Eames and Matte on November 21, 2007. The Board of Directors approved the fiscal year 2008 target bonus amount for Mr. McAdam on November 21, 2007.
 
(3) 50% of the cash incentive bonus is based on the Company achieving target revenue for the quarter and 50% is based on the Company achieving target adjusted EBITDA for the quarter. No cash incentive bonus will be paid for results less than 80% of an applicable target. The cash incentive bonus is paid on a linear basis above 80% of the targeted goals. For example, 85% of the possible cash incentive bonus will be paid for revenue or adjusted EBITDA at 85% of the applicable target. Similarly, 105% of the possible cash incentive bonus will be paid for revenue or adjusted EBITDA at 105% of the applicable target. However, results for both targets must equal or exceed 100% for the total cash incentive bonus to be paid at 100% or more. In fiscal year 2008, the quarterly revenue targets for purposes of the Incentive Plan were $154.5 million, $160.9 million, $165.6 million and $176.2 million, for an annual target of $657.2 million; and the quarterly adjusted EBITDA targets were $27.7 million, $29.8 million, $33.4 million and $39 million, for an annual target of $129.9 million. The actual cash incentive bonus paid for fiscal year 2008 is set forth above in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table for Fiscal 2008.

(4) Represents (i) 25% of the aggregate number of RSUs in the grant dated August 1, 2008 which are subject to the Company achieving an increase in total revenue during the period beginning in the fourth quarter of fiscal year 2008 through the third quarter of fiscal year 2009, relative to the same periods in fiscal years 2007 and 2008 (the “2008 Performance Award”); and (ii) 25% which are subject to the Company meeting specified performance criteria as will be set by the Compensation Committee for the period beginning in the fourth quarter of fiscal year 2009 through the third quarter of fiscal year 2010, relative to the same periods in fiscal years 2008 and 2009. The executive officers earn 125% of the 2008 Performance Award if the revenue increase is 20%, 100% of the 2008 Performance Award if the revenue increase is 11%, and 75% of the 2008 Performance Award if the revenue increase is 6%. No portion of the 2008 Performance Award is earned if the revenue increase is less than 6%.
 
(5) Represents 50% of the aggregate number of RSUs in the grant dated August 1, 2008 which vest in equal quarterly increments over two years, until such portion of the grant is fully vested on August 1, 2010. The holder of the RSU award does not have any of the benefits of ownership of the shares of Common Stock subject to the award, such as the right to vote the shares or to receive dividends, unless and until the RSU vests and the shares are issued.
 
(6) The column shows the full grant date fair value of RSUs in accordance with FAS 123R granted to the Named Executive Officers in fiscal 2008. Generally, the full grant date fair value is the amount the Company would expense in its financial statements over the vesting period of the award. The grant date fair value of the Equity Incentive Plan Awards is calculated based on the target payout. For additional information, please refer to note 1 in our financial statements, “Summary of Significant Accounting Policies — Stock-Based Compensation,” included in our Annual Report to Shareholders on Form 10-K for the year ended September 30, 2008. These amounts reflect the Company’s accounting expense for those awards, rather than the amount paid or to be realized by the Named Executive Officers.

Potential Payments Upon Termination or Change in Control
 
There are no written employment contracts with any of the Named Executive Officers. Each such officer is an “at-will” employee, and his employment may be terminated anytime with or without cause. The RSU and option grant agreements issued to our Named Executive Officers provide that upon certain changes in control of the Company the vesting of outstanding and unvested RSUs and options will accelerate and such RSUs and options will become fully vested. A “change in control” is generally defined as (i) a sale of substantially all of the assets of the Company, or (ii) a merger or consolidation in which the Company is not the surviving corporation, or (iii) a reverse merger in which the Company is the surviving corporation but the shares of Common Stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise, or (iv) the direct or indirect acquisition (including by way of a tender or exchange offer) by any person, or persons acting as a group, of beneficial ownership or a right to acquire beneficial ownership of shares representing a majority of the voting power of the then outstanding shares of capital stock of the Company. All options granted to Named Executive Officers are now fully vested.
 
The following table sets forth an estimate of the value of the acceleration of vesting on unvested equity awards that would have occurred if a change in control occurred on September 30, 2008.

(3) Represents the dollar amount recognized for financial statement reporting purposes during fiscal year 2008 for RSUs granted to directors in fiscal years 2008 and 2007, in accordance with FAS 123R. The amounts shown exclude the impact of estimated forfeitures related to service-based vesting conditions. Mr. Malone’s term on the Board of Directors expired on the date of the Company’s annual meeting for fiscal year 2007. The difference in Mr. Thompson’s dollar amount reflects the vesting of the pro-rata fiscal year 2007 grant of 1,632 RSUs when he joined the Board of Directors in January 2008. For additional information, please refer to note 1 in our financial statements, “Summary of Significant Accounting Policies — Stock-Based Compensation,” included in our Annual Report to Shareholders on Form 10-K for the year ended September 30, 2008. These amounts reflect the Company’s accounting expense for these awards, rather than the amount paid or to be realized by the directors. On January 18, 2008, the Board of Directors approved the recommendations of the Compensation Committee that (i) Mr. Thompson receive a grant on February 1, 2008 of RSUs representing the right to receive 1,632 shares of Common Stock (with a grant date fair value of $40,833 in accordance with FAS 123R) which will fully vest on March 10, 2008; and (ii) each non-employee director, including Mr. Thompson, receive a grant on March 11, 2008 of RSUs representing the right to receive 10,215 shares of Common Stock under the 2005 Plan (with a grant date fair value of $200,010 in accordance with FAS 123R) which will fully vest on March 11, 2009 if the non-employee director continues to serve as a director on that date. As of September 30, 2008, these 10,215 RSUs awarded to each non-employee director were the only RSUs held by each such director which were not yet vested.
 
Report of the Audit Committee
 
The Audit Committee consists of three directors, each of whom, in the judgment of the Board of Directors, is an “independent director” as defined in the listing standards for The Nasdaq Stock Market. The Audit Committee acts pursuant to a written charter that has been adopted by the Board of Directors. The Audit Committee charter is available on the “About F5 — Investor Relations — Corporate Governance” section of the Company’s website, www.f5.com.
 
On behalf of the Board of Directors, the Audit Committee oversees the Company’s financial reporting process and its internal controls over financial reporting, areas for which management has the primary responsibility. PricewaterhouseCoopers, LLP, the independent registered public accounting firm (the “Auditors”), is responsible for expressing an opinion as to the conformity of the audited financial statements with

Table of Contents

accounting principles generally accepted in the United States of America and for issuing its opinions on management’s assessment and on the effectiveness of the Company’s internal control over financial reporting.
 
In fulfilling its oversight responsibilities, the Audit Committee has reviewed and discussed with management and the Auditors the audited financial statements and the quarterly unaudited financial statements of the Company for the fiscal year ended September 30, 2008, matters relating to the Company’s internal controls over financial reporting and the processes that support certifications of the financial statements by the Company’s Chief Executive Officer and Chief Accounting Officer.
 
The Audit Committee discussed with the Auditors the overall scope and plans for the annual audit. The Audit Committee meets with the Auditors, with and without management present, to discuss the results of their examinations, their consideration of the Company’s internal controls in connection with their audit, and the overall quality of the Company’s financial reporting.
 
The Audit Committee reviewed with the Auditors their judgments as to the quality and acceptability of the Company’s accounting principles and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards. The Audit Committee has discussed and reviewed with the Auditors all matters required to be discussed under the Statement on Auditing Standards No. 61 Communication with Audit Committees.
 
The Audit Committee has received from the Auditors a formal written statement describing all relationships between them and the Company that might bear on their independence consistent with Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees), discussed with them any relationships that may impact their objectivity and independence, including the amount and significance of non-audit services provided by them, and has satisfied itself as to their independence.
 
Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors (and the Board has approved) that the audited financial statements be included in the Annual Report to Shareholders on Form 10-K for the year ended September 30, 2008 for filing with the Securities and Exchange Commission. The Audit Committee has also selected PricewaterhouseCoopers, LLP as the Company’s independent registered public accounting firm for the fiscal year ending September 30, 2009. The Board of Directors is recommending that shareholders ratify this selection at the Annual Meeting.

The Audit Committee also meets with our independent registered public accounting firm, on a quarterly basis, following completion of their quarterly reviews and annual audit and prior to our earnings announcements, to review the results of their work. During the course of the year, the Chairman of the Audit Committee has the authority to pre-approve requests for services that were not approved in the annual pre-approval process. The Chairman of the Audit Committee reports any interim pre-approvals at the following quarterly meeting. At each of the meetings, management and our independent registered public accounting firm update the Audit Committee with material changes to any service engagement and related fee estimates as compared to amounts previously approved. During fiscal 2008, all audit and non-audit services performed by PricewaterhouseCoopers LLP for the Company were pre-approved by the Audit Committee in accordance with the foregoing procedures.
 
Annual Independence Determination
 
The Audit Committee considered whether the provision of non-audit services is compatible with the principal accountants’ independence and concluded that the provision of non-audit services is and has been compatible with maintaining the independence of the Company’s external auditors.

Section 16 (a) Beneficial Ownership Reporting Compliance
 
Under SEC rules, the Company’s directors, executive officers and beneficial owners of more than 10% of any class of equity security registered under Section 12 of the Exchange Act are required to file periodic reports of their ownership, and changes in that ownership, with the SEC. Such persons are required by SEC regulations to furnish us with copies of all Section 16(a) forms filed by such person. Based solely on its review of copies of these reports and representations of such reporting persons, the Company believes that, during fiscal year 2008, all such SEC filing requirements were satisfied with the following exceptions:

executive officers Jeffrey Christianson and Karl Triebes each failed to file one Form 4 with respect to a reportable transaction during fiscal year 2008.
 
PROPOSAL 1:  ELECTION OF ONE CLASS I DIRECTOR
 
At the Annual Meeting, the shareholders will vote on the election of one Class I director to serve for a three-year term until the annual meeting of shareholders for fiscal year end 2011 and until the director’s successor is elected and qualified. The Board of Directors has unanimously nominated Karl D. Guelich for re-election to the Board of Directors as a Class I director. The nominee has indicated that he is willing and able to serve as a director. If the nominee becomes unable or unwilling to serve, the accompanying proxy may be voted for the election of such other person as shall be designated by the Board of Directors. The proxies being solicited will be voted for no more than one nominee for a Class I director at the Annual Meeting.
 
Majority Vote Standard for Director Election
 
The Company’s Bylaws require that in an uncontested election each director will be elected by the vote of the majority of the votes cast. A majority of votes cast means that the number of shares cast “for” a director’s election exceeds the number of votes cast “against” that director. A share whose ballot is marked as withheld, which is otherwise present at the meeting but for which there is an abstention, or to which a shareholder gives no authority or direction shall not be considered a vote cast. In a contested election, the directors will be elected by the vote of a plurality of the votes cast. A contested election is one in which the number of nominees exceed the number of directors to be elected.
 
In an uncontested election, a nominee who does not receive a majority vote will not be elected. Except as explained in the next paragraph, an incumbent director who is not elected because he or she does not receive a majority vote will continue to serve as a holdover director until the earliest of: (a) 90 days after the date on which an inspector determines the voting results as to that director; (b) the date on which the Board of Directors appoints an individual to fill the office held by that director; or (c) the date of the director’s resignation.
 
The Board of Directors may fill any vacancy resulting from the non-election of a director as provided in our Bylaws. The Nominating and Corporate Governance Committee will consider promptly whether to fill the office of a nominee who fails to receive a majority vote in an uncontested election and make a recommendation to the Board of Directors about filling the office. The Board of Directors will act on the Governance and Nominating Committee’s recommendation and within ninety (90) days after the certification of the shareholder vote will disclose publicly its decision. No director who fails to receive a majority vote for election will participate in the Governance and Nominating Committee’s recommendation or Board of Directors’ decision about filling his or her office.
 
For additional information, the complete Bylaws are available on our website at www.f5.com under the “About F5 — Investor Relations — Corporate Governance” section.
 
THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR”
THE ELECTION OF THE NOMINEE.
 
Unless otherwise instructed, it is the intention of the persons named in the accompanying proxy card to vote shares represented by properly executed proxy cards for the election of Mr. Guelich.
 
PROPOSAL 2.  AMENDMENT TO THE 2005 EQUITY INCENTIVE PLAN
 
At the Annual Meeting, the shareholders of the Company will be asked to approve an amendment to the 2005 Plan which, if approved, will increase the number of shares of Common Stock available for purchase under the 2005 Plan by 5,000,000 shares. The 2005 Plan is the Company’s primary equity incentive plan. Currently, there are no other equity incentive plans from which the Company can issue options and stock


25


Table of Contents

units. As of January 8, 2009, only 1,937,068 shares remained available for the future grant of equity awards under the 2005 Plan.
 
No other amendments to the 2005 Plan are being proposed. This amendment to the 2005 Plan was approved by the Board of Directors on January 7, 2009 and will become effective upon receipt of the shareholders’ approval at the Annual Meeting. The affirmative vote of the holders of a majority of the outstanding shares of Common Stock of the Company represented and voting on the proposal at the Annual Meeting is required to adopt the amendment to the 2005 Plan.
 
The Board of Directors believes that the 2005 Plan has contributed to strengthening the incentive of participating employees to achieve the objectives of the Company and its shareholders by encouraging employees to acquire a greater proprietary interest in the Company. The Board of Directors believes that additional shares must be reserved for use under the 2005 Plan to enable the Company to attract and retain key employees through the granting of options and stock units under the 2005 Plan. The proposed increase in the number of shares under the 2005 Plan is not required or intended to cover awards previously made under the 2005 Plan. As such, no new plan benefits have been granted to date, and future awards under the 2005 Plan are not yet determinable. In the event that the required votes to approve the amendment to the 2005 Plan are not obtained, the amendment to the 2005 Plan will not become effective and the Company will continue to make grants of awards pursuant to the terms of the 2005 Plan as currently in effect and subject to applicable law.
 
Summary of the 2005 Plan
 
A copy of the 2005 Plan, as amended, is attached to this Proxy Statement as Appendix A and is incorporated herein by reference. The following description of the 2005 Plan is a summary and does not purport to be a complete description. See Appendix A for more detailed information.
 
General.  The 2005 Plan provides for grants of nonstatutory stock options (“NSOs”), which are options that do not qualify as incentive stock options under Section 422 of the Code, and stock units (collectively, “Stock Awards”) to employees, including officers, or directors of and consultants to the Company or any affiliate of the Company. As of January 8, 2009, approximately 1,700 employees and five non-employee directors are eligible to participate in the 2005 Plan. As of January 8, 2009, a total of 3,473,126 shares had been issued upon the vesting and/or exercise of previously granted Stock Awards, options to purchase 60,000 shares remained outstanding and 1,937,068 shares remained available for the future grant of Stock Awards. Shares subject to Stock Awards that have lapsed or terminated, without having been exercised in full, may again become available for the grant of awards under the 2005 Plan.
 
The Board of Directors or a committee appointed by the Board of Directors (in either case, the “Administrator”) administers the 2005 Plan. The Administrator has broad discretionary authority to determine which recipients and what types of awards are to be granted, including the exercise price, if any, applicable to awards, the number of shares subject to awards, the vesting and/or exercisability of awards and any other terms and conditions (including forfeiture conditions) that apply to awards. Any award may be granted either alone or in tandem with other awards.
 
The Board of Directors may amend the 2005 Plan; provided that no amendment will be effective unless approved by the shareholders of the Company if shareholder approval is necessary to satisfy applicable laws or stock exchange listing requirements. In addition, shareholder approval is required if the exercise price of any outstanding option is to be reduced (other than as a result of certain adjustments to outstanding Stock Awards to reflect corporate capital transactions, such as stock splits, a change in control of the Company or other reorganizations). The 2005 Plan will terminate on December 30, 2014, unless terminated sooner by the Board of Directors.
 
If any change is made to the Common Stock without receipt of consideration by the Company (through merger, reorganization, stock split, stock dividend, combination of shares or similar change to the capital structure), the 2005 Plan and each outstanding Stock Award will be appropriately adjusted in (1) the number and kind of shares subject to the 2005 Plan, (2) the share limitations set forth in the 2005 Plan (including the


26


Table of Contents

limit of 2,000,000 shares that may be granted to any employee in any fiscal year), (3) the number and kind of shares covered by each outstanding Stock Award and (4) the exercise or purchase price per share subject to each outstanding Stock Award.
 
Section 162(m) Limitations.  Section 162(m) of the Code generally disallows a tax deduction to public companies for compensation in excess of $1 million paid during any single year to the Company’s Chief Executive Officer or any of the three other most highly compensated officers (excluding the Company’s chief executive officer and principal accounting officer). Certain “performance-based” compensation is specifically exempt from this deduction limit if it meets the requirements specified in Section 162(m) and the regulations thereunder. One of the requirements for equity compensation awards, such as stock options, to qualify as performance-based compensation is that the shareholder-approved plan under which the awards are granted must include a limit on the number of shares granted to any one employee under the plan. Accordingly, the 2005 Plan provides that no employee may be granted Stock Awards covering more than 2,000,000 shares in any fiscal year. The Company believes that certain Stock Awards granted under the 2005 Plan can qualify as performance-based compensation, and therefore compensation amounts arising in connection with such Stock Awards will probably not be subject to the deduction limitation rule of Section 162(m). Stock units with service-based vesting generally do not qualify as performance-based compensation so that compensation amounts arising in connection with such stock units may be subject to this deduction limitation rule.
 
Options.  Any Options granted under the 2005 Plan are NSOs. The term of options granted under the 2005 Plan may not exceed 10 years. The per share exercise price of all options must be at least equal to the fair market value of a share of Common Stock on the date the option is granted. The closing price of the Common Stock as reported on the Nasdaq Global Market on January 8, 2009 was $24.12 per share. The 2005 Plan permits payment of an exercise price to be made by cash, check, wire transfer, other shares of Company Common Stock (with some restrictions), broker assisted same-day sales, any other form of consideration permitted by applicable law and acceptable to the Board of Directors or any combination thereof. Options granted under the 2005 Plan vest at the rate specified in the option agreement.
 
An optionee may not transfer options other than by will or the laws of descent or distribution, provided that an optionee may designate a beneficiary who may exercise the option following the optionee’s death. An optionee whose relationship with the Company or any related corporation ceases for any reason, except by death or permanent and total disability, generally may exercise vested options up to three months following cessation. Vested options may generally be exercised for up to 12 months after an optionee’s relationship with the Company or any affiliate of the Company ceases due to disability and for generally up to 18 months after the relationship with the Company or any affiliate of the Company ceases due to death. However, options may terminate or expire sooner or later as may be determined by the Board of Directors and set forth in the option agreement.
 
Stock Units.  Stock Units under the 2005 Plan are Stock Awards other than options giving the right to receive shares of Common Stock. Each stock unit agreement will contain provisions regarding (1) the number of shares subject to such Stock Award, (2) the purchase price of the shares, if any, and the means of payment for the shares, (3) the performance or other criteria, if any, that will determine the number of shares vested, (4) such terms and conditions on the grant, issuance, vesting and forfeiture of the shares, as applicable, as may be determined from time to time by the Board of Directors or other administrator of the 2005 Plan, (5) restrictions on the transferability of the Stock Award, and (6) such further terms and conditions, in each case not inconsistent with the 2005 Plan, as may be determined from time to time by the Board of Directors or other administrator of the 2005 Plan. In the event that a participant’s relationship with the Company terminates, the Company may reacquire any or all of the shares of Common Stock held by the participant that have not vested or which are otherwise subject to forfeiture conditions. Rights under a stock unit agreement may not be transferred other than by will or by the laws of descent and distribution. The repurchase provision in the 2005 Plan was amended in January 2007 to clarify that the provision applies only to Stock Units and was subject to the 2005 Plan’s adjustment provisions for changes in capitalization and change in control of the Company.
 
The 2005 Plan also provides that Stock Awards, including Options, may not be repriced, cancelled and replaced with Stock Awards bearing a lower purchase or exercise price or exchanged for cash, subject to the


27


Table of Contents

2005 Plan’s adjustment provisions for changes in capitalization, such as stock splits, a change in control of the Company or other reorganizations.
 
Change in Control Provisions.  Subject to the provisions of any Stock Award Agreement, upon certain changes in control of the Company as provided under the 2005 Plan, the surviving entity will either assume or substitute all outstanding Stock Awards under the 2005 Plan. If the surviving entity determines not to assume or substitute these awards, then with respect to persons whose service with the Company or any affiliate of the Company has not terminated before the change in control, the vesting of 50% of these Stock Awards (and the time during which these awards may be exercised) will accelerate and the awards will terminate if not exercised before the change in control.
 
Stock Awards Granted to Certain Persons.  All Stock Awards to directors, executive officers, and employees under the 2005 Plan are made at the discretion of the Administrator. Therefore, the benefits and amounts that will be received or allocated under the amended 2005 Plan are not determinable at this time. No Stock Awards have been granted that are contingent on the approval of the proposed amendment to the 2005 Plan. As of January 8, 2009, there were (i) 60,000 shares of Common Stock subject to outstanding options at an exercise price of $26.865 and with an expiration date of February 24, 2015; and (ii) 1,929,806 shares of Common Stock subject to outstanding unvested Stock Awards other than options.
 
For information regarding grants made to our Named Executive Officers under the 2005 Plan in respect of fiscal year 2008 performance, see the table entitled “Grants of Plan-Based Awards in Fiscal 2008” above. During fiscal year 2008, the Company issued no options and 1,700,162 Stock Units under the 2005 Plan with a per share weighted average grant date fair value of $29.13. 429,400 Stock Units were granted to all current executive officers as a group (“Executive Group”); 62,922 Stock Units were granted to all current directors who are not executive officers as a group (“Non-Executive Director Group”); and 1,207,840 Stock Units were granted to all employees, including current officers who are not executive officers, as a group (“Non-Executive Officer Employee Group”). The proposed amendment to the 2005 Plan would have had no impact on these amounts had it been in place during fiscal year 2008.
 
Certain Federal Income Tax Consequences
 
THE FOLLOWING SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES IS BASED UPON EXISTING STATUTES, REGULATIONS AND INTERPRETATIONS THEREOF. THE APPLICABLE RULES ARE COMPLEX, AND INCOME TAX CONSEQUENCES MAY VARY DEPENDING UPON THE PARTICULAR CIRCUMSTANCES OF EACH PLAN PARTICIPANT. THIS PROXY STATEMENT DESCRIBES FEDERAL INCOME TAX CONSEQUENCES OF GENERAL APPLICABILITY, BUT DOES NOT PURPORT TO DESCRIBE PARTICULAR CONSEQUENCES TO EACH INDIVIDUAL PLAN PARTICIPANT, OR FOREIGN, STATE OR LOCAL INCOME TAX CONSEQUENCES, WHICH MAY DIFFER FROM THE UNITED STATES FEDERAL INCOME TAX CONSEQUENCES.
 
Stock option grants under the 2005 Plan are intended to be NSOs. Generally, no federal income tax is payable by a participant upon the grant of a stock option and no deduction is taken by the Company at that time. Under current tax laws, if a participant exercises a NSO as to vested shares (meaning, shares that are not subject to a substantial risk of forfeiture as further described below), he or she will recognize compensation income equal to the difference between the fair market value of the Common Stock on the exercise date and the stock option exercise price. The Company will be entitled to a corresponding deduction on its income tax return. Options granted under the 2005 Plan will generally not permit recipients to exercise the options as to unvested shares.
 
Generally, no taxes are due when a Stock Unit award is initially made, but the recipient will recognize taxable income when the shares subject thereto are no longer subject to a “substantial risk of forfeiture” (i.e. the shares subject thereto become vested or transferable, generally on the date the shares are issued to the recipient upon vesting). Income tax is paid on the value of the stock at ordinary income rates when the restrictions lapse and the units are converted to shares of Common Stock, and then at capital gain rates when the shares are sold. In certain cases, the participant may be eligible to make an election under Section 83(b) of


28


Table of Contents

the Code, in which case the timing of the tax recognition event and the amount of income recognized will differ from that described above.
 
Section 162(m) Limitations
 
As discussed above, as a public company, the Company is subject to the tax-deduction rule of Section 162(m) of the Code (applicable to compensation in excess of $1 million paid to certain of the Company’s executive officers during any year). The 2005 Plan includes a limitation on the number of shares that may be granted subject to awards made to an employee during any fiscal year to permit the Company to qualify certain Stock Awards granted under the 2005 Plan as performance-based compensation, which is excepted from the general tax-deduction rule. The Section 162(m) limit in the 2005 Plan is 2,000,000 shares per fiscal year. Stock options issued under the 2005 Plan will generally qualify as performance-based compensation, while stock units with service based vesting will generally not qualify as performance-based compensation, and therefore compensation amounts arising in connection with stock units with service based vesting may be subject to the Section 162(m) tax deduction rule.
 
Section 409A of the Code
 
If an award under the 2005 Plan constitutes nonqualified deferred compensation that is subject to Section 409A of the Code, certain requirements must be met (e.g., rules regarding deferral elections, distributions and acceleration of benefits). If the requirements are not satisfied, the participant may have to include an amount in income currently (or, if later, when no longer subject to a substantial risk of forfeiture), and may be subject to an additional tax equal to 20% of the amount included in income plus interest from the date of deferral (at the IRS underpayment rate plus 1%). NSOs are generally exempted from the requirements of Section 409A of the Code if certain requirements are satisfied (e.g., if the exercise price can never be less than the fair market value of the stock on the grant date).
 
To the extent that the payments or benefits provided under the 2005 Plan are considered deferred compensation subject to Section 409A of the Code, the Company intends for the 2005 Plan to comply with the standards for nonqualified deferred compensation established by Section 409A.
 
Accounting Treatment
 
The Company accounts for stock-based compensation in accordance with Financial Accounting Standards Board (“FASB”) Statement No. 123(R), “Share-Based Payment” (“FAS 123R”), using the straight-line attribution method for recognizing compensation expense. The value of RSUs is determined using the fair value method, which is based on the number of shares granted and the quoted price of the Company’s common stock on the date of grant. In determining the fair value of stock options, the Company uses the Black-Scholes option pricing model. FAS 123R also requires that the Company recognize compensation expense for only the portion of stock options or RSUs that are expected to vest. Estimated forfeiture rates are derived from historical employee termination behavior. Compensation costs for awards with performance conditions are recognized when the Company concludes it is probable that the performance condition will be achieved.

PROPOSAL 3.  AMENDMENT TO THE 1999 EMPLOYEE STOCK PURCHASE PLAN
 
At the Annual Meeting, the Company’s shareholders are being asked to approve the amendment of the ESPP and the reservation of 2,000,000 additional shares of Common Stock for issuance thereunder. The ESPP originally authorized the issuance of 2,000,000 shares and was subsequently amended, with the approval of the


29


Table of Contents

Company’s shareholders on April 29, 2004 to increase the shares issuable under the ESPP by 2,000,000 shares. As of January 8, 2009, 749,964 shares were available for future purchases. Without a further increase, the ESPP would run out of shares. Therefore, the Company believes an increase is prudent to make available sufficient shares for issuance under the ESPP on an ongoing basis. On January 7, 2009, the Board of Directors approved an increase of 2,000,000 shares issuable under the ESPP, subject to shareholder approval. The affirmative vote of the holders of a majority of the outstanding shares of Common Stock of the Company represented and voting on this proposal at the Annual Meeting is required to adopt the amendment to the ESPP. On January 8, 2009, the closing price of a share of the Company’s common stock as reported on the Nasdaq Global Market was $24.12.
 
The following is a summary of principal features of the ESPP and its operation. A copy of the ESPP, as amended, is attached to this Proxy Statement as Appendix B and is incorporated herein by reference. The following description of the ESPP is a summary and does not purport to be a complete description. See Appendix B for more detailed information.
 
General
 
The ESPP was adopted by the Board of Directors in April 1999 and amended in 2004. In connection with the 2009 amendment of the ESPP, the Board of Directors has reserved a total of 2,000,000 additional shares of Common Stock for issuance thereunder. The Board of Directors believes that, in order to attract qualified employees to the Company and to provide incentives to its current employees, it is necessary to grant its employees the right to purchase Common Stock of the Company pursuant to the ESPP. Accordingly, the shareholders are being asked to approve the amendment to the ESPP.
 
The ESPP is implemented by offerings and purchase periods, each six months in duration, that commence on May 1 and November 1 of each year, or at such other time or times as may be determined by the Board of Directors. The first offering period commenced on June 4, 1999. The ESPP is intended to qualify under Section 423 of the Code. The ESPP and options granted thereunder shall contain, and the shares issued upon exercise thereof shall be subject to, any additional conditions and restrictions as may be required by Rule 16b-3 of the Exchange Act to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to ESPP transactions.
 
Purpose
 
The purpose of the ESPP is to provide employees (including officers and employee directors) of the Company with an opportunity to purchase Common Stock of the Company through payroll deductions.
 
Administration
 
The ESPP is to be administered by the Board of Directors of the Company or a committee appointed by the Board. At the present time, the ESPP is administered by the Compensation Committee of the Board of Directors. All questions of interpretation or application of the ESPP are determined by the Administrator.
 
Eligibility and Participation
 
Employees (including officers and employee directors) who are employed for at least 20 hours per week and more than five months in any calendar year and who are employed by the Company as of the first business day of each offering period of the plan (the “Offering Date”) are eligible to participate in an offering under the ESPP, subject to certain limitations imposed by Section 423(b) of the Code and limitations on stock ownership as set forth in the ESPP. As of January 8, 2009, approximately 1,700 employees are eligible to participate in the ESPP. No employee shall be granted an option under the ESPP if (i) immediately after the grant such employee would own stock and/or hold outstanding options to purchase stock possessing five percent (5%) or more of the total voting power or value of all classes of stock of the Company or its subsidiaries, or (ii) such option would permit such employee to purchase stock under all employee stock purchase plans of the Company and its subsidiaries to accrue at a rate which exceeds $25,000 of fair market value of such stock for each calendar year in which such option is outstanding at any time.


30


Table of Contents

Eligible employees become participants in the ESPP by filing with the payroll department of the Company a subscription agreement authorizing payroll deductions prior to the applicable Offering Date, unless a later time for filing the subscription agreement has been set by the Administrator. Payroll deductions shall commence on the first payroll following the Offering Date and shall end on the last payroll paid on or prior to the last day (the “Purchase Date”) of the offering period to which the subscription agreement is applicable, unless sooner terminated by the participant.
 
Grant and Exercise of Option
 
At the beginning of an offering period, each participant is granted an option to purchase up to that number of shares determined by dividing such employee’s payroll deductions accumulated prior to the end of the offering period and retained in the participant’s account as of the end of the offering period at a purchase price determined as set forth below; provided that in no event is a participant permitted to purchase during each calendar year for which an option is outstanding more than a number of shares determined by dividing $25,000 by the fair market value of a share of the Common Stock at the beginning of the offering period, and provided further that such purchases are subject to the limitations set forth below. The Company may make a pro rata reduction in the number of shares subject to options if the total number of shares which would otherwise be subject to options granted at the beginning of an offering period exceeds the number of remaining available shares in the ESPP. Unless an employee withdraws his or her participation in the ESPP by giving written notice to the Company of his or her election to withdraw all accumulated payroll deductions prior to the end of an offering period, the employee’s option for the purchase of shares will be exercised automatically at the end of the offering period, and the maximum number of full shares subject to the option which are purchasable with the accumulated payroll deductions in his or her account will be purchased at the applicable purchase price determined as provided below.
 
During his or her lifetime, a participant’s option to purchase shares under the ESPP is exercisable only by him or her. However, a participant may file a written designation of a beneficiary who is (i) to receive any shares and cash, if any, from the participant’s account under the ESPP in the event of such participant’s death subsequent to the end of an offering period but prior to delivery to him or her of such shares and cash, and (ii) to receive any cash from the participant’s account under the ESPP in the event of such participant’s death prior to the Purchase Date of the applicable offering period. If a participant is married and the designated beneficiary is not the spouse, spousal consent is required for such designation to be effective.
 
Purchase Price
 
The purchase price per share at which shares are sold to participating employees under the ESPP is the lower of (i) 85% of the fair market value per share of the Common Stock at the time the option is granted at the commencement of the offering period, and (ii) 85% of the fair market value per share of the Common Stock at the time the option is exercised on the applicable Purchase Date. The fair market value of the Common Stock on a given date shall be determined by the Board of Directors and will generally be based upon the last reported sales price of the Common Stock on the Nasdaq National Market.
 
Payroll Deductions
 
The purchase price of the shares to be acquired under the ESPP is accumulated by payroll deductions during the offering period. The deductions may not be more than 15% of a participant’s aggregate compensation during the offering period. A participant may discontinue his or her participation in the ESPP during an offering period. Payroll deductions for a participant shall commence on the first payroll following the Offering Date and shall continue until his or her participation is terminated as provided in the ESPP.
 
Termination of Employment
 
Termination of a participant’s employment for any reason, including retirement or death, or the failure of the participant to remain in the continuous employ of the Company for at least 20 hours per week during the applicable offering period, cancels his or her option and his or her participation in the ESPP immediately. In


31


Table of Contents

such event, the payroll deductions credited to the participant’s account will be returned to him or her or, in the case of death, to the person or persons entitled thereto as provided in the ESPP.
 
Adjustments Upon Changes in Capitalization
 
In the event any change is made in the Company’s capitalization in the middle of an offering period, such as a stock split, stock dividend, combination or reclassification, that results in an increase or decrease in the number of shares of Common Stock outstanding without receipt of consideration by the Company, appropriate adjustment shall be made in the purchase price and in the number of shares subject to options under the ESPP.
 
In the event of a proposed dissolution or liquidation of the Company, the offering period will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Administrator. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each option under the ESPP shall be assumed or an equivalent substitute option shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation. If the options are not assumed or substituted, the Administrator may elect to shorten the offering period then in progress by setting a new Purchase Date prior to the consummation of such sale or merger and notifying the optionees of the change in their Purchase Date.
 
Purchases under the ESPP by Certain Persons
 
The aggregate number of shares of Common Stock purchased under the ESPP since its inception are as follows: (i) John McAdam, President, Chief Executive Officer and a director, 16,829 shares; (ii) John E. Rodriguez, Senior VP and Chief Accounting Officer, 15,961 shares; (iii) Edward Eames, Senior VP of Business Operations, 14,560 shares; (iv) Dan Matte, Senior VP of Marketing, 18,019 shares; (v) Karl Triebes, Senior VP of Product Development and Chief Technology Officer, no shares; (vi) the Executive Group, an aggregate of 88,373 shares; and (vii) the Non-Executive Officer Employee Group, an aggregate of 3,161,663 shares. Non-employee directors are not eligible to participate in the ESPP. Since its inception, no shares have been purchased under the ESPP by any associate of any such director, nominee or executive officer, and no other person has purchased five percent or more of the total amount of options granted under the ESPP.
 
New Plan Benefits
 
No purchase rights have been granted, and no shares have been issued, on the basis of the 2,000,000 share increase, which is the subject of this proposal. Because benefits under the ESPP will depend on employees’ elections to participate and the fair market value of the Company’s common stock at various future dates, it is not possible to determine the benefits that will be received by executive officers and other employees if the share increase is approved by the shareholders. Non-employee directors are not eligible to participate in the ESPP. However, during the fiscal year ended September 30, 2008, the following persons or groups purchased

shares of common stock under the ESPP as follows, at a price per share determined as described above of $30.6255 (October 31, 2007 purchase) and $19.2355 (April 30, 2008 purchase):

Amendment and Termination of the Plan
 
The Board of Directors may at any time amend or terminate the ESPP without the approval of the shareholders, except that such termination cannot affect options previously granted nor may an amendment make any change in an option granted prior thereto which adversely affects the rights of any participant. No amendment may be made to the ESPP without approval of the shareholders of the Company if such amendment would increase the number of shares reserved under the ESPP, change the standards of eligibility for participation in the ESPP or materially increase the benefits accruing to participants in the ESPP.
 
The ESPP has no expiration date.
 
Tax Information
 
The ESPP, and the right of participants to make purchases thereunder, is intended to qualify under the provisions of Sections 421 and 423 of the Code. Under these provisions, no income will be taxable to a participant until the shares purchased under the Plan are sold or otherwise disposed of. Upon sale or other disposition of the shares, the participant will generally be subject to tax and the amount of the tax will depend upon how long the shares have been held by the participant. If the shares are sold or otherwise disposed of more than two years from the first day of the offering period and more than one year after the applicable Purchase Date, the participant will recognize ordinary income measured as the lesser of (a) the excess of the fair market value of the shares at the time of such sale or disposition over the purchase price, or (b) an amount equal to 15% of the fair market value of the shares as of the first day of the offering period. Any additional gain will be treated as long-term capital gain if the shares are held for more than one year after the Purchase Date. If the shares are sold or otherwise disposed of before the expiration of these holding periods, 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 such sale or disposition will be long-term or short-term capital gain or loss, depending on the holding period. The Company is not entitled to a deduction for amounts taxed as ordinary income or capital gain to a participant except to the extent of ordinary income recognized by participants upon a sale or disposition of shares prior to the expiration of the holding period(s) described above.

THE BOARD RECOMMENDS A VOTE “FOR”
APPROVAL OF THIS PROPOSAL
 
Unless instructed otherwise, it is the intention of the persons named in the accompanying proxy card to vote shares represented by properly executed proxy cards or electronic ballots for this proposal.
 
PROPOSAL 4.  RATIFICATION OF INDEPENDENT AUDITOR
 
The Board of Directors requests that the shareholders ratify the selection of PricewaterhouseCoopers LLP as the Company’s independent auditor for the fiscal year ending September 30, 2009. The Company expects that representatives of PricewaterhouseCoopers will be present at the annual meeting to make a statement if they desire to do so and to respond to questions by shareholders.
 
Although not required by the Company’s Bylaws or otherwise, the Audit Committee and the Board of Directors believe it appropriate, as a matter of good corporate practice, to request that the shareholders ratify the appointment of PricewaterhouseCoopers LLP as the Company’s independent auditor for fiscal 2009. If the shareholders do not so ratify, the Audit Committee will reconsider the appointment and may retain PricewaterhouseCoopers LLP or another firm without re-submitting the matter to the Company’s shareholders. Even if the shareholders vote on an advisory basis in favor of the appointment, the Audit Committee may, in its discretion, direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and the shareholders.
 
THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR”

Neither the Board of Directors nor management intends to bring before the Annual Meeting any business other than the matters referred to in the Notice of Meeting and this Proxy Statement. If any other business should properly come before the Annual Meeting, or any adjournment thereof, the persons named in the proxy will vote on such matters according to their best judgment.
 
SHAREHOLDER PROPOSALS FOR THE ANNUAL MEETING FOR FISCAL YEAR END 2009
 
The Company’s Bylaws provide that advance notice of a shareholder’s proposal must be delivered to or mailed and received at the Company’s principal executive offices not later than the close of business on the ninetieth (90th) day, nor earlier than the close of business on the one hundred twentieth (120th) day prior to the first anniversary of the preceding year’s annual meeting. However, the Bylaws also provide that in the event the date of the annual meeting has been changed by more than thirty (30) days from the date contemplated at the time of the previous year’s proxy statement, this advance notice must be received not earlier than the close of business on the ninetieth (90th) day prior to such annual meeting, and not later than the close of business on the later of the sixtieth (60th) day prior to such annual meeting or, in the event public announcement of the date of such annual meeting is first made by the Company fewer than seventy (70) days prior to the date of such annual meeting, the close of business on the tenth (10th) day following the day on which public announcement of the date of such meeting is first made by the Company. Each shareholder’s


34


Table of Contents

notice must contain the following information as to each matter the shareholder proposes to bring before the annual meeting: (A) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting, (B) the name and address, as they appear on the Company’s books, of the shareholder proposing such business, (C) the class and number of shares of the Company which are beneficially owned by the shareholder, (D) any material interest of the shareholder in such business and (E) any other information that is required to be provided by the shareholder pursuant to Regulation 14A under the Exchange Act, in such shareholder’s capacity as a proponent of a shareholder proposal.
 
A copy of the full text of the provisions of the Company’s Bylaws dealing with shareholder nominations and proposals is available to shareholders from the Secretary of the Company upon written request.
 
Shareholders who intend to have a proposal considered for inclusion in the Company’s proxy materials for presentation at the Annual Meeting for fiscal year end 2009 must submit the proposal to the Company no earlier than November 11, 2009 and no later than December 11, 2009. Shareholders who intend to present a proposal at the Annual Meeting for fiscal year end 2009 without inclusion of such proposal in the Company’s proxy materials are required to provide notice of such proposal to the Company no later than December 11, 2009 or management of the Company will have discretionary voting authority at the fiscal year end 2009 annual meeting with respect to any such proposal without discussion of the matter in proxy statement for such meeting. The Company reserves the right to reject, rule out of order, or take appropriate action with respect to any proposal that does not comply with these and other applicable requirements.
 
HOUSEHOLDING OF PROXY MATERIALS
 
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and Annual Reports to Shareholders with respect to two or more shareholders sharing the same address by delivering a single proxy statement addressed to those shareholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for shareholders and cost savings for the Company by reducing printing and postage costs. Under this procedure, the Company will deliver only one copy of the Company’s Annual Report to Shareholders for fiscal year 2008 (the “2008 Annual Report”) and this proxy statement to multiple shareholders who share the same address (if they appear to be members of the same family), unless the Company has received contrary instructions from an affected shareholder.
 
The 2008 Annual Report and this proxy statement may be found under the “About F5 — Investor Relations — Corporate Governance” section of the Company’s website at www.f5.com. The Company will deliver promptly upon written or oral request a separate copy of the 2008 Annual Report and this proxy statement to any shareholder at a shared address to which a single copy of either of those documents was delivered. To receive a separate copy of the 2008 Annual Report or this proxy statement, shareholders should contact the Company at: Investor Relations, F5 Networks, Inc., 401 Elliott Avenue West, Seattle, Washington 98119. The Company’s telephone number at that location is 206-272-5555.
 
If you are a shareholder, share an address and last name with one or more other shareholders and would like either to request delivery of a single copy of the Company’s Annual Report to Shareholders or proxy statements for yourself and other shareholders who share your address or to revoke your householding consent and receive a separate copy of the Company’s Annual Report to Shareholders or proxy statement in the future, please contact Broadridge Financial Solutions, Inc. (“Broadridge”), either by calling toll free at (800) 542-1061 or by writing to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717. You will be removed from the householding program within 30 days of receipt of the revocation of your consent.

(i) To determine from time to time which of the persons eligible under the Plan shall be granted Stock Awards; when and how each Stock Award shall be granted; what type or combination of types of Stock Awards shall be granted; the provisions, terms and conditions of each Stock Award granted (which need not be identical as among Participants or as among types of Stock Awards), including, without limitation: the time or times when a person shall be permitted to receive Shares pursuant to a Stock Award, the number of Shares with respect to which a Stock Award shall be granted to each such person, the exercise or purchase price (if any) of a Stock Award, the time or times when Stock Awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, any pro rata adjustment to vesting as a result of a Participant’s transitioning from full- to part-time service (or vice versa), and any other restriction (including forfeiture restriction), limitation or term of any Stock Award, based in each case on such factors as the Board, in its sole discretion, shall determine; provided, however, that such provisions, terms and conditions are not inconsistent with the terms of the Plan.
 
(ii) In order to fulfill the purposes of the Plan and without amending the Plan, to modify grants of Stock Awards to Participants who are foreign nationals or employed outside of the United States in order to recognize differences in local law, tax policies or customs.
 
(iii) To construe and interpret the Plan and Stock Awards granted under it, and to establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan or in any Stock Award Agreement, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully effective.
 
(iv) To amend the Plan or a Stock Award as provided in Section 12.
 
(v) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests of the Company which are not in conflict with the provisions of the Plan.
 
(c) Delegation to Committee.  The Board may delegate administration of the Plan to a Committee or Committees of one or more members of the Board, and the term “Committee” shall apply to any person or persons to whom such authority has been delegated. In the discretion of the Board, the Committee may consist solely of two or more Outside Directors, in accordance with Section 162(m) of the Code, and/or solely of two or more Non-Employee Directors, in accordance with Rule 16b-3, and/or solely of two or more Independent


A-3


Table of Contents

Directors under applicable Nasdaq (or other exchange) rules. The Board or the Committee may further delegate its authority and responsibilities under the Plan to an Officer. However, if administration is delegated to an Officer, such Officer may grant Stock Awards only within guidelines established by the Board or the Committee, and only the Board or the Committee may make a Stock Award to an Officer or Director. If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board, including the power to delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board shall thereafter be to the Committee or subcommittee, or an Officer to whom authority has been delegated), subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may abolish the Committee at any time and revest in the Board the administration of the Plan, and unless otherwise specified by the Board shall retain any authority granted to a committee or individual hereunder unto itself.
 
4.  Shares Subject to the Plan.
 
(a) Share Reserve.  Subject to the provisions of Section 11 relating to adjustments upon changes in stock, the stock that may be issued pursuant to Stock Awards shall not exceed in the aggregate Twelve Million Four Hundred Thousand (12,400,000)1 Shares of Common Stock.
 
(b) Section 162(m) Limitation on Share Numbers.  No Employee shall be eligible to be granted Stock Awards covering more than Two Million (2,000,000) Shares during any fiscal year of the Company.
 
(c) Reversion of Shares to the Share Reserve.  If any Stock Award shall for any reason expire or otherwise terminate, in whole or in part, without having been exercised in full, the Shares not acquired under such Stock Award shall revert to and again become available for issuance under the Plan. Further, if any previously-issued Shares are forfeited under the terms and conditions of the Stock Award, then any Shares so forfeited shall revert to and again become available for issuance under the Plan. The provisions of this Section 4(c) are qualified by Section 4(a) such that the total number of Shares issued and outstanding under the Plan at any time may not exceed the number set forth in Section 4(a) (as adjusted under Section 11).
 
(d) Source of Shares.  The stock subject to the Plan may be unissued Shares or reacquired Shares, bought on the market or otherwise.
 
5.   Eligibility.
 
Stock Awards may be granted to Employees, Directors and Consultants.
 
6.   Option Provisions.
 
Each Option shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The provisions of separate Options need not be identical, but each Option shall include (through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions:
 
(a) Term.  No Option shall be exercisable after the expiration of ten (10) years from the date it was granted.
 
(b) Exercise Price of an Option.  The exercise price of each Option shall be at least equal to the Fair Market Value of the stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, an Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner satisfying the provisions of Section 424(a) of the Code.
 
(c) Consideration.  The purchase price of stock acquired pursuant to an Option shall be paid, to the extent permitted by applicable statutes and regulations, either (i) in cash, check or wire transfer at the

Table of Contents

time the Option is exercised or (ii) at the discretion of the Board at the time of the grant of the Option or subsequently by (1) by delivery to the Company of other Shares that have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which the Option is exercised, provided that in the case of Shares acquired, directly or indirectly, from the Company, such Shares must have been owned by the Participant for more than six (6) months on the date of surrender (or such other period as may be required to avoid the Company’s incurring an adverse accounting charge), (2) if, as of the date of exercise of an Option the Company then is permitting Employees to engage in a “same-day sale” cashless brokered exercise program involving one or more brokers, through such a program that complies with the Applicable Laws (including without limitation the requirements of Regulation T and other applicable regulations promulgated by the Federal Reserve Board) and that ensures prompt delivery to the Company of the amount required to pay the exercise price and any applicable withholding taxes, (3) in any other form of legal consideration that may be acceptable to the Board, or (4) any combination of the foregoing methods. In making its determination as to the type of consideration to accept, the Board shall consider if acceptance of such consideration may be reasonably expected to benefit the Company and the Board may, in its sole discretion, refuse to accept a particular form of consideration at the time of any Option exercise.
 
(d) Transferability of an Option.  The Option shall not be transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Participant only by the Participant. Notwithstanding the foregoing provisions of this subsection 6(d), the Participant may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Participant, shall thereafter be entitled to exercise the Option.
 
(e) Vesting.
 
(i) Generally.  The total number of Shares of Common Stock subject to an Option may, but need not, vest and therefore become exercisable in periodic installments which may, but need not, be equal. The Option may be subject to such other terms and conditions on the time or times when it may be exercised (which may be based on performance or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options may vary. The provisions of this subsection 6(e) are subject to any Option provisions governing the minimum number of Shares as to which an Option may be exercised.
 
(ii) Leave of Absence.  The Board (or any other party to whom such authority has been delegated, including under this Plan) shall have the discretion to determine whether and to what extent the vesting of Options shall be tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, vesting of Options shall be tolled during any such unpaid leave (unless otherwise required by the Applicable Laws). In the event of military leave, vesting shall toll during any unpaid portion of such leave, provided that, upon a Participant’s returning from military leave (under conditions that would entitle him or her to protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be given vesting credit with respect to Options to the same extent as would have applied had the Participant continued to provide services to the Company throughout the leave on the same terms as he or she was providing services immediately prior to such leave.
 
(f) Termination of Continuous Service.  In the event a Participant’s Continuous Service terminates (other than upon the Participant’s death or Disability), the Participant may exercise his or her Option (to the extent that the Participant was vested in the Option Shares and entitled to exercise such Option as of the date of termination) but only within such period of time ending on the earlier of (i) the date three (3) months following the termination of the Participant’s Continuous Service (or such longer or shorter period specified in the Option Agreement), or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Participant does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate.
 
(g) Extension of Termination Date.  Following the termination of the Participant’s Continuous Service (other than upon the Participant’s death or Disability), if the Participant would be prohibited at


A-5


Table of Contents

any time solely because the issuance of Shares would violate the registration requirements under the Securities Act or violate any prohibition on trading on the basis of possession of material nonpublic information involving the Company and its business, then the Option shall terminate on the earlier of (i) the expiration of the term of the Option set forth in subsection 6(a), or (ii) the expiration of a period of three (3) months after the termination of the Participant’s Continuous Service during which the exercise of the Option would not be in violation of such requirements.
 
(h) Disability of Participant.  In the event a Participant’s Continuous Service terminates as a result of the Participant’s Disability, the Participant may exercise his or her Option (to the extent that the Participant was vested in the Option Shares and entitled to exercise the Option as of the date of termination), but only within such period of time ending on the earlier of (i) the date twelve (12) months following such termination (or such longer or shorter period specified in the Option Agreement) or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Participant does not exercise his or her Option within the time specified herein, the Option shall terminate.
 
(i) Death of Participant.  In the event (i) an Participant’s Continuous Service terminates as a result of the Participant’s death or (ii) the Participant dies within the period (if any) specified in the Option Agreement after the termination of the Participant’s Continuous Service for a reason other than death, then the Option may be exercised (to the extent the Participant was vested in the Option Shares and entitled to exercise the Option as of the date of death) by the Participant’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the Option upon the Participant’s death pursuant to subsection 6(d), but only within the period ending on the earlier of (1) the date eighteen (18) months following the date of death (or such longer or shorter period specified in the Option Agreement) or (2) the expiration of the term of such Option as set forth in the Option Agreement. If, after death, the Option is not exercised within the time specified herein, the Option shall terminate.
 
(j) Exercise Generally.  Options shall be considered exercised when the Company (or its authorized agent) receives (i) written or electronic notice from the person entitled to exercise the Option of intent to exercise a specific number of Shares, (ii) full payment or appropriate provision for payment in a form and method acceptable to the Board or Committee, for the Shares being exercised, and (iii) if applicable, payment or appropriate provision for payment of any withholding taxes due on exercise. An Option may not be exercised for a fraction of a Share. The Option may, at the discretion of the Board or Committee, include a provision whereby the Participant may elect to exercise the Option as to Shares that are not yet vested. Unvested Shares exercised in such manner may be subject to a Company repurchase right under Section 10(f) or such other restrictions or conditions as the Board or Committee may determine.
 
(k) Administrator Discretion.  Notwithstanding the provisions of this Section 6, the Board or the Committee shall have complete discretion exercisable at any time to (i) extend the period of time for which an Option is to remain exercisable, following the Participant’s termination of Continuous Service, but in no event beyond the expiration date for the Option, and (ii) permit the Option to be exercised, during the applicable post-termination exercise period, not only with respect to the number of Shares that were vested on the date of termination, cut also with respect to additional Shares on such terms and conditions as the Board or Committee may determine.
 
7.   Provisions of Stock Awards other than Options.
 
Each Stock Award Agreement reflecting the issuance of a Stock Unit shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The terms and conditions of such agreements may change from time to time, and the terms and conditions of separate agreements need not be


A-6


Table of Contents

identical, but each such agreement shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:
 
(a) Consideration.  A Stock Unit may be awarded in consideration for such property or services as is permitted under Applicable Law, including for past services actually rendered to the Company or an Affiliate for its benefit.
 
(b) Vesting; Restrictions.  Shares of Common Stock awarded under the agreement reflecting a Stock Unit award may, but need not, be subject to a Share repurchase option, forfeiture restriction or other conditions in favor of the Company in accordance with a vesting or lapse schedule to be determined by the Board.
 
(c) Termination of Participant’s Continuous Service.  In the event a Participant’s Continuous Service terminates, the Company may reacquire any or all of the Shares of Common Stock held by the Participant which have not vested or which are otherwise subject to forfeiture or other conditions as of the date of termination under the terms of the agreement.
 
(d) Transferability.  Rights to acquire Shares of Common Stock under a Stock Unit agreement shall not be transferable except by will or by the laws of descent and distribution, and Shares of Common Stock issued upon vesting of a Stock Unit shall be issuable during the lifetime of the Participant only to the Participant. Notwithstanding the foregoing provisions of this subsection 7(d), the Participant may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Participant, shall thereafter be entitled to receive Shares of Common Stock issued upon vesting of a Stock Unit.
 
8.   Covenants of the Company.
 
(a) Availability of Shares.  During the terms of the Stock Awards, the Company shall keep available at all times the number of Shares of Common Stock required to satisfy such Stock Awards.
 
(b) Securities Law Compliance.  The Company shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell Shares upon exercise of the Stock Awards; provided, however, that this undertaking shall not require the Company to register under the Securities Act the Plan, any Stock Award or any stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell stock upon exercise of such Stock Awards unless and until such authority is obtained.
 
9.   Use of Proceeds from Stock; Unfunded Plan.
 
Proceeds from the sale of stock pursuant to Stock Awards shall constitute general funds of the Company. The Plan shall be unfunded. Although bookkeeping accounts may be established with respect to Participants who are granted Stock Awards hereunder, any such accounts will be used merely as a bookkeeping convenience. The Company shall not be required to segregate any asset which may at any time be represented by Stock Awards, nor shall this Plan be construed as providing for such segregation, nor shall the Company nor any party authorized to administer the Plan be deemed to be a trustee of stock or cash to be awarded under the Plan. Any liability of the Company to any Participant with respect to a Stock Award shall be based solely upon any contractual obligations which may be created by the Plan; no such obligation of the Company shall be deemed to be secured by any pledge or other encumbrance on any property of the Company. Neither the Company nor any party authorized to administer the Plan shall be required to give any security or bond for the performance of any obligation which may be created by this Plan.
 
10.   Miscellaneous.
 
(a) Acceleration of Exercisability and Vesting.  The Board shall have the power to accelerate the time at which a Stock Award may first be exercised or the time during which a Stock Award or any part thereof will


A-7


Table of Contents

vest, become exercisable or be settled in accordance with the Plan, notwithstanding the provisions in the Stock Award stating the time at which it may first vest, be exercised or be settled.
 
(b) Shareholder Rights.  No Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any Shares subject to such Stock Award unless and until such Participant has satisfied all requirements for exercise of the Stock Award pursuant to its terms.
 
(c) No Employment or other Service Rights.  Nothing in the Plan or any instrument executed or any Stock Award granted pursuant thereto shall confer upon any Participant or other holder of Stock Awards any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Stock Award was granted or shall affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be.
 
(d) Investment Assurances.  The Company may require a Participant, as a condition of exercising or acquiring Shares under any Stock Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Stock Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring the stock subject to the Stock Award for the Participant’s own account and not with any present intention of selling or otherwise distributing the stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if the issuance of the Shares upon the exercise or acquisition of stock under the Stock Award has been registered under a then currently effective registration statement under the Securities Act; or as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the stock.
 
(e) Withholding Obligations.  To the extent provided by the terms of a Stock Award Agreement, the Participant may satisfy any federal, state or local tax withholding obligation relating to the exercise or acquisition of Shares under a Stock Award by any of the following means (in addition to the Company’s right to withhold from any compensation paid to the Participant by the Company) or by a combination of such means: (i) tendering a cash payment; (ii) authorizing the Company to withhold Shares from the Shares otherwise issuable to the Participant as a result of the exercise or acquisition of stock under the Stock Award; or (iii) delivering to the Company owned and unencumbered Shares.
 
(f) Stock Unit Repurchase Limitation.  The terms of any repurchase option for a Stock Unit shall be specified in the Stock Award and may be at the Fair Market Value of the stock subject to the Stock Award at the time of repurchase, at the original price or on such terms and conditions as the Board may determine (and as shall be reflected in the Stock Award Agreement); provided however that this Section 10(f) shall in no way limit the Company’s ability to adjust any Stock Award as provided under Section 11 below.
 
(g) Cancellation and Re-Grant of Stock Awards.  The Company may not reprice any outstanding Stock Awards under the Plan, including implement any program whereby outstanding Stock Awards will be cancelled and replaced with Stock Awards bearing a lower purchase or exercise price or exchanged for cash, without first obtaining the approval of the shareholders of the Company; provided however that this Section 10(g) shall in no way limit the Company’s ability to adjust Stock Awards as provided under Section 11 below.
 
(h) Interpretation of Plan and Stock Awards.  In the event that any provision of the Plan or any Stock Award granted under the Plan is declared to be illegal, invalid or otherwise unenforceable by a court of competent jurisdiction, such provision shall be reformed, if possible, to the extent necessary to render it legal,


A-8


Table of Contents

valid and enforceable, or otherwise deleted, and the remainder of the terms of the Plan and/or Stock Award shall not be affected to the extent necessary to reform or delete such illegal, invalid or unenforceable provision. All questions arising under the Plan or under any Stock Award shall be decided by the Board or the Committee in its or their total and absolute discretion and such decisions shall be final and binding on all parties.
 
(i) Electronic Communication.  Any document required to be delivered under the Plan, including under the Applicable Laws, may be delivered in writing or electronically. Signature may also be electronic if permitted by the Board or the Committee, and if permitted by Applicable Law.
 
(j) Escrow of Shares.  To enforce any restriction applicable to Shares issued under the Plan, the Board or the Committee may require a Participant or other holder of such Shares to deposit the certificates representing such Shares, with approved stock powers or other transfer instruments endorsed in blank, with the Company or an agent of the Company until the restrictions have lapsed. Such certificates (or other notations representing the Shares) may bear a legend or legends referencing the applicable restrictions.
 
11.   Adjustments upon Changes in Stock.
 
(a) Capitalization Adjustments.  If any change is made in the stock subject to the Plan, or subject to any Stock Award, without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company), the Plan will be appropriately adjusted in the class(es) and maximum number of securities subject to the Plan pursuant to subsection 4(a) and the maximum number of securities subject to award to any person pursuant to subsection 4(b), and the outstanding Stock Awards will be appropriately adjusted in the class(es) and number of securities and price per Share of stock subject to such outstanding Stock Awards. The Board, the determination of which shall be final, binding and conclusive, shall make such adjustments. (The conversion of any convertible securities of the Company shall not be treated as a transaction “without receipt of consideration” by the Company.)
 
(b) Change in Control — Dissolution or Liquidation.  In the event of a dissolution or liquidation of the Company, then such Stock Awards shall be terminated if not exercised (if applicable) prior to such event.
 
(c) Change in Control — Asset Sale, Merger, Consolidation or Reverse Merger or Acquisition of Stock.
 
(i) In the event of (1) a sale of substantially all of the assets of the Company, or (2) a merger or consolidation in which the Company is not the surviving corporation, or (3) a reverse merger in which the Company is the surviving corporation but the shares of Common Stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise, or (4) the direct or indirect acquisition (including by way of a tender or exchange offer) by any person, or persons acting as a group, of beneficial ownership or a right to acquire beneficial ownership of shares representing a majority of the voting power of the then outstanding shares of capital stock of the Company, then any surviving corporation or acquiring corporation shall assume any Stock Awards outstanding under the Plan or shall substitute similar awards (including with respect to a Stock Award an award to acquire the same consideration paid to the shareholders in the transaction described in this subsection 11(c) for those outstanding under the Plan).
 
(ii) For purposes of subsection 11(c) a Stock Award shall be deemed assumed if, following the change in control, the Stock Award confers the right to purchase in accordance with its terms and conditions, for each share of Common Stock subject to the Stock Award immediately prior to the change in control, the consideration (whether stock, cash or other securities or property) to which a holder of a share of Common Stock on the effective date of the change in control was entitled.
 
(iii) Subject to the provisions of any Stock Award Agreement, in the event any surviving corporation or acquiring corporation refuses to assume such Stock Awards or to substitute similar stock awards for those outstanding under the Plan, then with respect to Stock Awards held by Participants whose Continuous Service has not terminated, the vesting of 50% of such Stock Awards (and, if applicable, the


A-9


Table of Contents

time during which such Stock Awards may be exercised or settled) shall be accelerated in full, and the Stock Awards shall terminate if not exercised or settled (if applicable) at or prior to such event. With respect to any other Stock Awards outstanding under the Plan, such Stock Awards shall terminate if not exercised (if applicable) prior to such event.
 
(iv) The Board shall at all times have the authority, in its sole discretion, to provide for additional or different vesting, exercisability, settlement or forfeiture conditions with respect to Stock Awards than that reflected in this Section 11(c), provided that its determinations in this regard shall be reflected in the Stock Award Agreement (including in amendments thereto) issued to the affected Participant.
 
12.   Amendment of the Plan and Stock Awards.
 
(a) Amendment of Plan.  The Board at any time, and from time to time, may amend the Plan. However, except as provided in Section 11 relating to adjustments upon changes in stock, no amendment shall be effective unless approved by the shareholders of the Company to the extent shareholder approval is necessary to satisfy the requirements of Rule 16b-3 or any Nasdaq or securities exchange listing requirements.
 
(b) Shareholder Approval.  The Board may, in its sole discretion, submit any other amendment to the Plan for shareholder approval, including, but not limited to, amendments to the Plan intended to satisfy the requirements of Section 162(m) of the Code and the regulations thereunder regarding the exclusion of performance-based compensation from the limit on corporate deductibility of compensation paid to certain executive officers.
 
(c) Contemplated Amendments.  It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide eligible Employees with the maximum benefits provided or to be provided under the provisions of the Code or any other Applicable Law.
 
(d) No Impairment of Rights.  Rights under any Stock Award granted before amendment of the Plan shall not be materially impaired by any amendment of the Plan unless (i) the Company requests the consent of the Participant and (ii) the Participant consents in writing.
 
(e) Amendment of Stock Awards.  The Board at any time, and from time to time, may amend the terms of any one or more Stock Awards; provided, however, that the rights under any Stock Award shall not be materially impaired by any such amendment unless (i) the Company requests the consent of the Participant and (ii) the Participant consents in writing.
 
13.   Termination or Suspension of the Plan.
 
(a) Plan Term.  The Board may suspend or terminate the Plan at any time. Unless sooner terminated, the Plan shall terminate on the day before the tenth (10th) anniversary of the date the Plan is adopted by the Board or approved by the shareholders of the Company, whichever is earlier. No Stock Awards may be granted under the Plan while the Plan is suspended or after it is terminated.
 
(b) No Impairment of Rights.  Suspension or termination of the Plan shall not materially impair rights and obligations under any Stock Award granted while the Plan is in effect except with the written consent of the Participant.
 
14.   Effective Date of Plan.
 
The Plan shall become effective as determined by the Board, but no Stock Award shall be exercised unless and until the Plan has been approved by the shareholders of the Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the Board.
 
15.   Governing Law.
 
All questions concerning the construction, validity and interpretation of this Plan shall be governed by the law of the State of Washington, without regard to such states conflict of laws rules.

(b) The Board may provide that each person who, during the course of an Offering, first becomes an Eligible Employee will, on a date or dates specified in the Offering which coincides with the day on which such person becomes an Eligible Employee or which occurs thereafter, receive a Right under that Offering, which Right shall thereafter be deemed to be a part of that Offering. Such Right shall have the same characteristics as any Rights originally granted under that Offering, as described herein, except that:
 
(i) the date on which such Right is granted shall be the “Offering Date” of such Right for all purposes, including determination of the exercise price of such Right;
 
(ii) the period of the Offering with respect to such Right shall begin on its Offering Date and end coincident with the end of such Offering; and
 
(iii) the Board may provide that if such person first becomes an Eligible Employee within a specified period of time before the end of the Offering, he or she will not receive any Right under that Offering.
 
(c) No Employee shall be eligible for the grant of any Rights under the Plan if, immediately after any such Rights are granted, such Employee owns stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or of any Affiliate. For purposes of this subparagraph 6(c), the rules of Section 424(d) of the Code shall apply in determining the stock ownership of any Employee, and stock which such Employee may purchase under all outstanding rights and options shall be treated as stock owned by such Employee.
 
(d) An Eligible Employee may be granted Rights under the Plan only if such Rights, together with any other Rights granted under all Employee Stock Purchase Plans of the Company and any Affiliates, as specified by Section 423(b)(8) of the Code, do not permit such Eligible Employee’s rights to purchase Shares of the Company or any Affiliate to accrue at a rate which exceeds twenty five thousand dollars ($25,000) of the fair market value of such Shares (determined at the time such Rights are granted) for each calendar year in which such Rights are outstanding at any time.
 
(e) The Board may provide in an Offering that Employees who are highly compensated Employees within the meaning of Section 423(b)(4)(D) of the Code shall not be eligible to participate.
 
7.   RIGHTS; PURCHASE PRICE.
 
(a) On each Offering Date, each Eligible Employee, pursuant to an Offering made under the Plan, shall be granted the Right to purchase up to the number of Shares purchasable either:
 
(i) with a percentage designated by the Board not exceeding fifteen percent (15%) of such Employee’s Earnings (as defined by the Board in each Offering) during the period which begins on the Offering Date (or such later date as the Board determines for a particular Offering) and ends on the date stated in the Offering, which date shall be no later than the end of the Offering; or
 
(ii) with a maximum dollar amount designated by the Board that, as the Board determines for a particular Offering, (1) shall be withheld, in whole or in part, from such Employee’s Earnings (as defined by the Board in each Offering) during the period which begins on the Offering Date (or such later date as the Board determines for a particular Offering) and ends on the date stated in the Offering, which date shall be no later than the end of the Offering and/or (2) shall be contributed, in whole or in part, by such Employee during such period.
 
(b) The Board shall establish one or more Purchase Dates during an Offering on which Rights granted under the Plan shall be exercised and purchases of Shares carried out in accordance with such Offering.
 
(c) In connection with each Offering made under the Plan, the Board may specify a maximum amount of Shares that may be purchased by any Participant as well as a maximum aggregate amount of Shares that may be purchased by all Participants pursuant to such Offering. In addition, in connection with each Offering that contains more than one Purchase Date, the Board may specify a maximum aggregate amount of Shares which may be purchased by all Participants on any given Purchase Date under the Offering. If the aggregate purchase


B-4


Table of Contents

of Shares upon exercise of Rights granted under the Offering would exceed any such maximum aggregate amount, the Board shall make a pro rata allocation of the Shares available in as nearly a uniform manner as shall be practicable and as it shall deem to be equitable.
 
(d) The purchase price of Shares acquired pursuant to Rights granted under the Plan shall be not less than the lesser of:
 
(i) an amount equal to eighty-five percent (85%) of the fair market value of the Shares on the Offering Date; or
 
(ii) an amount equal to eighty-five percent (85%) of the fair market value of the Shares on the Purchase Date.
 
8.   PARTICIPATION; WITHDRAWAL; TERMINATION.
 
(a) An Eligible Employee may become a Participant in the Plan pursuant to an Offering by delivering a participation agreement to the Company within the time specified in the Offering, in such form as the Company provides. Each such agreement shall authorize payroll deductions of up to the maximum percentage specified by the Board of such Employee’s Earnings during the Offering (as defined in each Offering). The payroll deductions made for each Participant shall be credited to a bookkeeping account for such Participant under the Plan and either may be deposited with the general funds of the Company or may be deposited in a separate account in the name of, and for the benefit of, such Participant with a financial institution designated by the Company. To the extent provided in the Offering, a Participant may reduce (including to zero) or increase such payroll deductions. To the extent provided in the Offering, a Participant may begin such payroll deductions after the beginning of the Offering. A Participant may make additional payments into his or her account only if specifically provided for in the Offering and only if the Participant has not already had the maximum permitted amount withheld during the Offering.
 
(b) At any time during an Offering, a Participant may terminate his or her payroll deductions under the Plan and withdraw from the Offering by delivering to the Company a notice of withdrawal in such form as the Company provides. Such withdrawal may be elected at any time prior to the end of the Offering except as provided by the Board in the Offering. Upon such withdrawal from the Offering by a Participant, the Company shall distribute to such Participant all of his or her accumulated payroll deductions (reduced to the extent, if any, such deductions have been used to acquire Shares for the Participant) under the Offering, without interest unless otherwise specified in the Offering, and such Participant’s interest in that Offering shall be automatically terminated. A Participant’s withdrawal from an Offering will have no effect upon such Participant’s eligibility to participate in any other Offerings under the Plan but such Participant will be required to deliver a new participation agreement in order to participate in subsequent Offerings under the Plan.
 
(c) Rights granted pursuant to any Offering under the Plan shall terminate immediately upon cessation of any participating Employee’s employment with the Company or a designated Affiliate for any reason (subject to any post-employment participation period required by law) or other lack of eligibility. The Company shall distribute to such terminated Employee all of his or her accumulated payroll deductions (reduced to the extent, if any, such deductions have been used to acquire Shares for the terminated Employee) under the Offering, without interest unless otherwise specified in the Offering. If the accumulated payroll deductions have been deposited with the Company’s general funds, then the distribution shall be made from the general funds of the Company, without interest. If the accumulated payroll deductions have been deposited in a separate account with a financial institution as provided in subparagraph 8(a), then the distribution shall be made from the separate account, without interest unless otherwise specified in the Offering.
 
(d) Rights granted under the Plan shall not be transferable by a Participant otherwise than by will or the laws of descent and distribution, or by a beneficiary designation as provided in paragraph 15 and, otherwise during his or her lifetime, shall be exercisable only by the person to whom such Rights are granted.

9.   EXERCISE.
 
(a) On each Purchase Date specified therefor in the relevant Offering, each Participant’s accumulated payroll deductions and other additional payments specifically provided for in the Offering (without any increase for interest) will be applied to the purchase of Shares up to the maximum amount of Shares permitted pursuant to the terms of the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional Shares shall be issued upon the exercise of Rights granted under the Plan unless specifically provided for in the Offering.
 
(b) Unless otherwise specifically provided in the Offering, the amount, if any, of accumulated payroll deductions remaining in any Participant’s account after the purchase of Shares that is equal to the amount required to purchase one or more whole Shares on the final Purchase Date of the Offering shall be distributed in full to the Participant at the end of the Offering, without interest. If the accumulated payroll deductions have been deposited with the Company’s general funds, then the distribution shall be made from the general funds of the Company, without interest. If the accumulated payroll deductions have been deposited in a separate account with a financial institution as provided in subparagraph 8(a), then the distribution shall be made from the separate account, without interest unless otherwise specified in the Offering.
 
(c) No Rights granted under the Plan may be exercised to any extent unless the Shares to be issued upon such exercise under the Plan (including Rights granted thereunder) are covered by an effective registration statement pursuant to the Securities Act and the Plan is in material compliance with all applicable state, foreign and other securities and other laws applicable to the Plan. If on a Purchase Date in any Offering hereunder the Plan is not so registered or in such compliance, no Rights granted under the Plan or any Offering shall be exercised on such Purchase Date, and the Purchase Date shall be delayed until the Plan is subject to such an effective registration statement and such compliance, except that the Purchase Date shall not be delayed more than twelve (12) months and the Purchase Date shall in no event be more than twenty-seven (27) months from the Offering Date. If, on the Purchase Date of any Offering hereunder, as delayed to the maximum extent permissible, the Plan is not registered and in such compliance, no Rights granted under the Plan or any Offering shall be exercised and all payroll deductions accumulated during the Offering (reduced to the extent, if any, such deductions have been used to acquire Shares) shall be distributed to the Participants, without interest unless otherwise specified in the Offering. If the accumulated payroll deductions have been deposited with the Company’s general funds, then the distribution shall be made from the general funds of the Company, without interest. If the accumulated payroll deductions have been deposited in a separate account with a financial institution as provided in subparagraph 8(a), then the distribution shall be made from the separate account, without interest unless otherwise specified in the Offering.
 
10.   COVENANTS OF THE COMPANY.
 
(a) During the terms of the Rights granted under the Plan, the Company shall ensure that the amount of Shares required to satisfy such Rights are available.
 
(b) The Company shall seek to obtain from each federal, state, foreign or other regulatory commission or agency having jurisdiction over the Plan such authority as may be required to issue and sell Shares upon exercise of the Rights granted under the Plan. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of Shares under the Plan, the Company shall be relieved from any liability for failure to issue and sell Shares upon exercise of such Rights unless and until such authority is obtained.
 
11.   USE OF PROCEEDS FROM SHARES.
 
Proceeds from the sale of Shares pursuant to Rights granted under the Plan shall constitute general funds of the Company.

12.   RIGHTS AS A SHAREHOLDER.
 
A Participant shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, Shares subject to Rights granted under the Plan unless and until the Participant’s Shares acquired upon exercise of Rights under the Plan are recorded in the books of the Company.
 
13.   ADJUSTMENTS UPON CHANGES IN SECURITIES.
 
(a) If any change is made in the Shares subject to the Plan, or subject to any Right, without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company), the Plan will be appropriately adjusted in the class(es) and maximum number of Shares subject to the Plan pursuant to subparagraph 4(a), and the outstanding Rights will be appropriately adjusted in the class(es), number of Shares and purchase limits of such outstanding Rights. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a transaction that does not involve the receipt of consideration by the Company.)
 
(b) In the event of: (i) a dissolution, liquidation, or sale of all or substantially all of the assets of the Company; (ii) a merger or consolidation in which the Company is not the surviving corporation; or (iii) a reverse merger in which the Company is the surviving corporation but the Shares outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise, then: (1) any surviving or acquiring corporation shall assume Rights outstanding under the Plan or shall substitute similar rights (including a right to acquire the same consideration paid to Shareholders in the transaction described in this subparagraph 13(b)) for those outstanding under the Plan, or (2) in the event any surviving or acquiring corporation refuses to assume such Rights or to substitute similar rights for those outstanding under the Plan, then, as determined by the Board in its sole discretion such Rights may continue in full force and effect or the Participants’ accumulated payroll deductions (exclusive of any accumulated interest which cannot be applied toward the purchase of Shares under the terms of the Offering) may be used to purchase Shares immediately prior to the transaction described above under the ongoing Offering and the Participants’ Rights under the ongoing Offering thereafter terminated.
 
14.   AMENDMENT OF THE PLAN.
 
(a) The Board at any time, and from time to time, may amend the Plan. However, except as provided in paragraph 13 relating to adjustments upon changes in securities and except as to minor amendments to benefit the administration of the Plan, to take account of a change in legislation or to obtain or maintain favorable tax, exchange control or regulatory treatment for Participants or the Company or any Affiliate, no amendment shall be effective unless approved by the shareholders of the Company to the extent shareholder approval is necessary for the Plan to satisfy the requirements of Section 423 of the Code, Rule 16b-3 under the Exchange Act and any Nasdaq or other securities exchange listing requirements. Currently under the Code, shareholder approval within twelve (12) months before or after the adoption of the amendment is required where the amendment will:
 
(i) Increase the amount of Shares reserved for Rights under the Plan;
 
(ii) Modify the provisions as to eligibility for participation in the Plan to the extent such modification requires shareholder approval in order for the Plan to obtain employee stock purchase plan treatment under Section 423 of the Code or to comply with the requirements of Rule 16b-3; or
 
(iii) Modify the Plan in any other way if such modification requires shareholder approval in order for the Plan to obtain employee stock purchase plan treatment under Section 423 of the Code or to comply with the requirements of Rule 16b 3.
 
(b) It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide Employees with the maximum benefits provided or to be provided under the


B-7


Table of Contents

provisions of the Code and the regulations promulgated thereunder relating to Employee Stock Purchase Plans and/or to bring the Plan and/or Rights granted under it into compliance therewith.
 
(c) Rights and obligations under any Rights granted before amendment of the Plan shall not be impaired by any amendment of the Plan, except with the consent of the person to whom such Rights were granted, or except as necessary to comply with any laws or governmental regulations, or except as necessary to ensure that the Plan and/or Rights granted under the Plan comply with the requirements of Section 423 of the Code.
 
15.   DESIGNATION OF BENEFICIARY.
 
(a) A Participant may file a written designation of a beneficiary who is to receive any Shares and/or cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death subsequent to the end of an Offering but prior to delivery to the Participant of such Shares and cash. In addition, a Participant may file a written designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of such Participant’s death during an Offering.
 
(b) The Participant may change such designation of beneficiary at any time by written notice. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company shall deliver such Shares and/or cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its sole discretion, may deliver such Shares and/or cash to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.
 
16.   TERMINATION OR SUSPENSION OF THE PLAN.
 
(a) The Board in its discretion may suspend or terminate the Plan at any time. Unless sooner terminated, the Plan shall terminate at the time that all of the Shares subject to the Plan’s reserve, as increased and/or adjusted from time to time, have been issued under the terms of the Plan. No Rights may be granted under the Plan while the Plan is suspended or after it is terminated.
 
(b) Rights and obligations under any Rights granted while the Plan is in effect shall not be impaired by suspension or termination of the Plan, except as expressly provided in the Plan or with the consent of the person to whom such Rights were granted, or except as necessary to comply with any laws or governmental regulation, or except as necessary to ensure that the Plan and/or Rights granted under the Plan comply with the requirements of Section 423 of the Code.
 
17.   EFFECTIVE DATE OF PLAN.
 
The Plan shall become effective as determined by the Board, but no Rights granted under the Plan shall be exercised unless and until the Plan has been approved by the shareholders of the Company within twelve (12) months before or after the date the Plan is adopted by the Board, which date may be prior to the effective date set by the Board.
