PROXY STATEMENT ---------- FOR THE ANNUAL MEETING OF SHAREHOLDERS OF NETWORK APPLIANCE, INC. To be held October 11, 2000 ---------- General This Proxy Statement is furnished in connection with the solicitation by the Board of Directors of Network Appliance, Inc., a California corporation (the "Company" or "Network Appliance"), of proxies to be voted at the Annual Meeting of Shareholders (the "Annual Meeting") to be held on October 11, 2000, or at any adjournment or postponement thereof, for the purposes set forth in the accompanying Notice of Annual Meeting of Shareholders. Shareholders of record on August 14, 2000 will be entitled to vote at the Annual Meeting. The Annual Meeting will be held at 3:00 p.m., local time, at the Company's headquarters, 495 East Java Drive, Sunnyvale, California 94089. It is anticipated that this Proxy Statement and the enclosed proxy card will be mailed to shareholders on or about August 28, 2000. All share numbers in this Proxy Statement reflect the two-for-one split of the Common Stock on December 20, 1999 and the two-for-one split of the Common Stock on March 22, 2000. Voting Rights The close of business on August 14, 2000 was the record date for shareholders entitled to notice of and to vote at the Annual Meeting and any adjournments thereof. At the record date, the Company had approximately 316,213,977 shares of its Common Stock, no par value, outstanding and entitled to vote at the Annual Meeting, and approximately 693 registered shareholders. No shares of the Company's Preferred Stock were outstanding. Holders of Common Stock are entitled to one vote for each share of Common Stock held by such shareholder on August 14, 2000. A majority of the shares of Common Stock entitled to vote will constitute a quorum for the transaction of business at the Annual Meeting. Abstentions and broker non-votes are counted as present for the purpose of determining the presence of a quorum. Shareholders may vote by proxy. The enclosed proxy is solicited by the Company's Board of Directors (the "Board of Directors" or the "Board") and when the proxy card is returned properly completed, it will be voted as directed by the shareholder on the proxy card. Shareholders are urged to specify their choices on the enclosed proxy card. If a proxy card is signed and returned without choices specified, in the absence of contrary instructions, the shares of Common Stock represented by such proxy will be voted FOR Proposals 1, 2, and 3 and will be voted in the proxy holders' discretion as to other matters that may properly come before the Annual Meeting. The eight director nominees receiving the highest number of affirmative votes will be elected. Votes against a nominee, abstentions and broker non-votes will have no effect. Approval of Proposals 2, and 3 requires (i) the affirmative vote of a majority of those shares present and voting and (ii) the affirmative vote of the majority of the required quorum. Thus, abstentions and broker non-votes can have the effect of preventing approval of a proposal where the number of affirmative votes, though a majority of the votes cast, does not constitute a majority of the required quorum. All votes will be tabulated by the inspector of the election appointed for the Annual Meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes. Revocability of Proxies Any person giving a proxy has the power to revoke it at any time before its exercise. You may revoke or change your proxy by filing with the Secretary of the Company an instrument of revocation or a duly executed proxy bearing a later date, or by attending the Annual Meeting and voting in person.

Solicitation of Proxies The Company will bear the cost of soliciting proxies. Copies of solicitation material will be furnished to brokerage houses, fiduciaries, and custodians holding shares in their names that are beneficially owned by others to forward to such beneficial owners. The Company may reimburse such persons for their costs of forwarding the solicitation material to such beneficial owners. The original solicitation of proxies by mail may be supplemented by solicitation by telephone, electronic communication, or other means by directors, officers, employees or agents of the Company. No additional compensation will be paid to these individuals for any such services. The Company may retain a proxy solicitor to assist in the solicitations of proxies, for which the Company would expect to pay an estimated fee of $12,500 plus reimbursement of expenses. Except as described above, the Company does not intend to solicit proxies other than by mail. Annual Report The Annual Report of the Company for the fiscal year ended April 28, 2000 has been mailed concurrently with the mailing of the Notice of Annual Meeting and Proxy Statement to all shareholders entitled to notice of and to vote at the Annual Meeting. The Annual Report is not incorporated into this Proxy Statement and is not considered proxy soliciting material. PROPOSAL NO. 1: ELECTION OF DIRECTORS At the Annual Meeting, eight directors (constituting the entire board) are to be elected to serve until the next Annual Meeting of Shareholders and until a successor for such director is elected and qualified, or until the death, resignation or removal of such director. It is intended that the proxies will be voted for the eight nominees named below for election to the Company's Board of Directors unless authority to vote for any such nominee is withheld. There are eight nominees, each of whom is currently a director of the Company. With the exception of Sachio Semmoto, all of the current directors were elected to the Board by the shareholders at the last Annual Meeting. Each person nominated for election has agreed to serve if elected, and the Board of Directors has no reason to believe that any nominee will be unavailable or will decline to serve. In the event, however, that any nominee is unable or declines to serve as a director at the time of the Annual Meeting, the proxies will be voted for any nominee who is designated by the current Board of Directors to fill the vacancy. Unless otherwise instructed, the proxyholders will vote the proxies received by them for the nominees named below. The eight candidates receiving the highest number of affirmative votes of the shares entitled to vote at the Annual Meeting will be elected directors of the Company. The proxies solicited by this Proxy Statement may not be voted for more than eight nominees. Nominees The directors of the Company, and their ages as of May 31, 2000, are as follows: Name Age Position - ---- --- -------- Daniel J.

Board Meetings and Committees The Board of Directors held seven (7) meetings during fiscal 2000. Each member of the Board of Directors during fiscal 2000 attended more than eighty percent (80%) of the aggregate of (i) the total number of meetings of the Board of Directors held during such period and (ii) the total number of meetings held during such period by all Committees of the Board on which he or she served. There are no family relationships among executive officers or directors of the Company. The Board of Directors has an Audit Committee and a Compensation Committee. The Audit Committee is comprised of Directors Ahuja, Carter and Hallman. The Audit Committee reviews, acts on and reports to the Board of Directors with respect to various auditing and accounting matters, including the selection of the Company's auditors, the scope of the annual audits, fees to be paid to the auditors, the performance of the Company's auditors and the accounting practices of the Company. The Audit Committee of the Board of Directors held five (5) meetings during fiscal 2000. The Compensation Committee, which is comprised of Directors Bartz and Wall, establishes salaries, incentives and other forms of compensation for officers and other employees of the Company and administers the incentive compensation and benefit plans of the Company. The Compensation Committee of the Board of Directors held one (1) meeting during fiscal 2000. In addition the Committee approved stock option grants on a monthly basis by means of Unanimous Written Consents. Director Compensation Directors of the Company do not receive compensation for services provided as a director. The Company also does not pay compensation for committee participation or special assignments of the Board of Directors. However, the directors are currently eligible to receive stock options under the Automatic Option Grant Program in effect under the 1999 Stock Option Plan (the "1999 Plan"), under which option grants are automatically made at periodic intervals to eligible non-employee Board members to purchase shares of Common Stock at an exercise price equal to 100% of the fair market value of the option shares on the grant date. At the 1999 Annual Shareholders Meeting held on October 26, 1999, each of the following individuals re-elected as a non-employee Board member at that meeting received an option grant for 40,000 shares of Common Stock under the Automatic Option Grant Program of the 1999 Plan with an exercise price of $16.66 per share, the fair market value per share of Common Stock on the grant date: Messrs. Valentine, Ahuja, Carter, Hallman, and Wall and Ms. Bartz. Dr. Semmoto received an option grant for 160,000 shares under the Automatic Option Grant Program of the 1999 Plan with an exercise price of $31.25 per share upon his appointment to the Board on December 1, 1999. Each automatic option has a term of 10 years, subject to earlier termination following the optionee's cessation of Board service, and is immediately exercisable for all the option shares. However, any shares purchased upon exercise of the option are subject to repurchase by the Company, at the option exercise price paid 4

per share, should the optionee cease service on the Board prior to vesting in those shares. The initial 160,000-share option grant made to a non-employee Board member under the Automatic Option Grant Program vests in a series of four (4) successive equal annual installments over the optionee's period of Board service measured from the grant date. Each annual option grant made to a continuing non-employee Board member vests upon the optionee's completion of one term of Board service measured from the grant date and continuing through the day immediately preceding the next Annual Meeting. However, each outstanding option will immediately vest upon (i) certain changes in the ownership or control of the Company or (ii) the death or disability of the optionee while serving as a Board member. On August 17, 2000, the Board amended the provisions of the Automatic Option Grant Program to decrease the number of shares of Common Stock for which option grants are to be made to new and continuing non-employee Board members from 160,000 shares to 40,000 shares for the initial option grant made to each individual who first becomes a non-employee Board member, provided such individual has not otherwise been in the prior employ of the company, and from 40,000 shares to 15,000 shares for the annual option grants to be made at each Annual Meeting to each individual who is to continue to serve as a non-employee Board member, provided such individual has served on the Board for at least six (6) months. The Board of Directors recommends that the shareholders vote FOR election of all of the above nominees for election as directors. PROPOSAL NO. 2: APPROVAL OF AMENDMENT TO THE 1999 STOCK OPTION PLAN General The shareholders are being asked to vote on a proposal to approve an amendment to the Company's 1999 Stock Option Plan (the "1999 Plan") which would increase the share reserve under that plan by an additional 15,000,000 shares of Common Stock. The Board of Directors (the "Board") approved the amendment on August 17, 2000, subject to shareholder approval at the Annual Meeting. The affirmative vote of a majority of the shares of Common Stock present or represented and voting at the Annual Meeting, together with the affirmative vote of the majority of the required quorum, is required for approval of the proposed share increase. The Board believes that the proposed increase to the share reserve under the 1999 Plan is necessary to assure that there will be a sufficient number of shares available for issuance under the 1999 Plan in order to attract and retain the services of individuals essential to the Company's long-term success. All share numbers which appear in this proposal reflect the two-for-one split of the Common Stock on December 20, 1999 and the two-for-one split of the Common Stock on March 22, 2000. Background The 1999 Plan was originally adopted by the Board and approved by the shareholders at the 1999 Annual Meeting held on October 26, 1999. The 1999 Plan is divided into two separate components: (i) the Discretionary Option Grant Program and (ii) the Automatic Option Grant Program. Under the Discretionary Option Grant Program, individuals in the Company's service may, at the discretion of the Plan Administrator, be granted options to purchase shares of Common Stock at an exercise price not less than the fair market value of those shares on the grant date. Under the Automatic Option Grant Program, option grants are automatically made at periodic intervals to non-employee members of the Board. In addition to the 1999 Plan, the Company also maintains two other equity incentive programs for individuals in the Company's service: the 1995 Stock Incentive Plan (the "1995 Plan") and the Special Non-Officer Stock Option Plan (the "Non-Officer Plan"). 1995 Plan The 1995 Plan became effective on November 20, 1995 in connection with the initial public offering of the Company's Common Stock. The 1995 Plan is currently divided into three separate components: (i) the 5

Discretionary Option Grant Program under which individuals in the Company's service may, at the discretion of the Compensation Committee, be granted options to purchase shares of Common Stock at an exercise price per share not less than the fair market value on the grant date, (ii) the Stock Issuance Program under which such individuals may, at the discretion of the Compensation Committee, be issued shares of Common Stock directly, through the purchase of such shares at a price per share not less than the fair market value at the time of issuance or as a fully paid bonus for services rendered the Company or the attainment of designated performance goals, and (iii) the Salary Investment Option Grant Program under which the Company's executive officers and other highly-compensated employees may elect to have a portion of their base salary applied each year to pre-payment of two-thirds of the exercise price of special option grants, the remaining one-third to be paid at the time of the option exercise. The shareholders have previously approved a reserve of 101,700,192 shares of Common Stock under the 1995 Plan. As of May 31, 2000, options covering 64,937,183 shares of Common Stock were outstanding under the 1995 Plan, 2,357,942 shares remained available for future option grants and direct stock issuances, and 33,868,075 shares had been issued. The Non-Officer Plan The Non-Officer Plan was adopted by the Board on April 30, 1997. Options may be granted under the Non-Officer Plan to employees of the Company (or any parent or subsidiary corporation) who are not officers or Board members. Each option grant will have an exercise price per share not less than the fair market value on the grant date and will generally become exercisable in a series of installments over the optionee's period of service with the Company. 6,400,000 shares of Common Stock were authorized by the Board for issuance under the Non-Officer Plan. As of May 31, 2000, options covering 4,306,725 shares of Common Stock were outstanding under the Non-Officer Plan, 227,644 shares remained available for future option grants, and 1,865,631 shares had been issued. Share issuances under the 1999 Plan will not reduce or otherwise affect the number of shares of Common Stock available for issuance under the 1995 Plan or the Non-Officer Plan, and share issuances under those two plans will not reduce or otherwise affect the number of shares of Common Stock available for issuance under the 1999 Plan. 1999 Plan Information The following is a summary of the principal features of the 1999 Plan. This summary, however, does not purport to be a complete description of all the provisions of the 1999 Plan. Any shareholder who wishes to obtain a copy of the actual plan document may do so by sending a written request to the attention of the Corporate Secretary at the Company's corporate offices in Sunnyvale, California. Administration The 1999 Plan (other than the Automatic Option Grant Program) is administered by the Compensation Committee of the Board. This committee (the "Plan Administrator") will have complete discretion (subject to the provisions of the 1999 Plan) to authorize option grants under the 1999 Plan. However, all grants under the Automatic Option Grant Program will be made in strict compliance with the provisions of that program, and the Plan Administrator will exercise no administrative discretion with respect to the grants made thereunder. Securities Subject to 1999 Plan Assuming shareholder approval of this Proposal, 28,200,000 shares of the Company's Common Stock will be authorized for issuance over the 10-year term of the 1999 Plan. As of May 31, 2000, options for 3,435,000 shares were outstanding, and 24,765,000 shares remained available for future option grants, assuming shareholder approval of this Proposal. The shares will be made available either from the Company's authorized but unissued Common Stock or from Common Stock reacquired by the Company. 6

In no event may one individual participating in the 1999 Plan be granted stock options for more than 3,000,000 shares of Common Stock in the aggregate per calendar year. Shareholder approval of this Proposal will also constitute reapproval of such limitation. In the event any change is made to the Common Stock issuable under the 1999 Plan by reason of any stock split, stock dividend, combination of shares, merger, reorganization, consolidation, recapitalization, exchange of shares, or other change in capitalization of the Company affecting the Common Stock as a class without the Company's receipt of consideration, appropriate adjustments will be made to (i) the maximum number and/or class of securities issuable under the 1999 Plan, (ii) the maximum number and/or class of securities for which any one individual may be granted stock options under the 1999 Plan per calendar year, (iii) the class and/or number of securities and option price per share in effect under each outstanding option and (iv) the class and/or number of securities for which automatic option grants are to be subsequently made to both new and continuing non-employee Board members under the Automatic Option Grant Program. The adjustments to the outstanding options will prevent the dilution or enlargement of benefits thereunder. The grant of stock options or stock appreciation rights under the 1999 Plan will not affect the right of the Company to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate, sell, or transfer all or any part of its business or assets. Eligibility Employees (including officers) and consultants and other independent advisors in the service of the Company (or its parent or subsidiary companies) who contribute to the management, growth and financial success of the Company (or its parent or subsidiary companies) will be eligible to participate in the Discretionary Option Grant Program of the 1999 Plan. The non-employee Board members are eligible to participate in the Automatic Grant Program. As of May 31, 2000, 1,583 employees (including 5 executive officers) were eligible to participate in the Discretionary Option Grant Program, and the 7 non-employee Board members were eligible to receive grants under the Automatic Option Grant Program. Valuation The fair market value per share of Common Stock under the 1999 Plan on any relevant date will be the closing selling price on the date in question, as reported on the Nasdaq National Market. On May 31, 2000, the fair market value per share of the Common Stock determined on such basis was $64.56 per share. Shareholder Rights and Option Transferability No optionee will have any shareholder rights with respect to the option shares until such optionee has exercised the option and paid the exercise price for the purchased shares. Options are generally not assignable or transferable other than by will or the laws of inheritance and, during the optionee's lifetime, the option may be exercised only by such optionee. However, the Plan Administrator may allow non-statutory options to be transferred or assigned during the optionee's lifetime to one or more members of the optionee's immediate family or to a trust established exclusively for one or more such family members, to the extent such transfer or assignment is in furtherance of the optionee's estate plan. Discretionary Option Grant Program Options granted under the Discretionary Option Grant Program may be either incentive stock options under the federal tax laws or non-statutory options which are not intended to meet such requirements. The principal features of the grants made under the Discretionary Option Grant Program may be summarized as follows: Price and Exercisability The exercise price per share must not be less than 100% of the fair market value per share of the Common 7

Stock on the grant date. No option may be outstanding for more than a 10-year term. The options will generally become exercisable in a series of installments over the optionee's period of service with the Company. The exercise price is payable in cash or with shares of the Company's common stock. The exercise price may also be paid through a same-day sale program, pursuant to which a designated brokerage firm is to effect the immediate sale of the shares purchased under the option and pay over to the Company, out of the sale proceeds available on the settlement date, sufficient funds to cover the exercise price for the purchased shares plus all applicable withholding taxes. Termination of Service The Plan Administrator has complete discretion to establish the period of time for which any option is to remain exercisable following the optionee's cessation of service with the Company. Under no circumstances may an option be exercised after the specified expiration date of the option term. Each option under the Discretionary Option Grant Program will be exercisable only to the extent of the number of shares for which such option is exercisable at the time of the optionee's cessation of employment or service. However, the Plan Administrator has the discretion, exercisable at any time while the option remains outstanding, to accelerate the exercisability and/or vesting of such option in whole or in part. The shares of Common Stock acquired upon the exercise of one or more options may be unvested and subject to repurchase by the Company, at the original exercise price paid per share, upon the optionee's cessation of service prior to vesting in such shares. The Plan Administrator will have complete discretion in establishing the vesting schedule for any such unvested shares and will have full authority to cancel the Company's outstanding repurchase rights with respect to one or more unvested shares held by the optionee and may exercise this discretion at any time, whether before or after the optionee's service actually ceases. Cancellation and Regrant of Options The Plan Administrator has the authority to effect the cancellation of any or all options outstanding under the Discretionary Option Grant Program and to grant in substitution therefor new options covering the same or different numbers of shares of common stock but with an exercise price per share not less than 100% of the fair market value of the common stock on the new grant date. However, such option cancellation/regrant program will be subject to the following two limitations: (i) only options held by employees who are neither executive officers of the Company nor members of the Board may be so cancelled and regranted and (ii) the total number of shares subject to options which are so cancelled and regranted from time to time will not in the aggregate exceed ten percent (10%) of the total number of shares of Common Stock authorized for issuance under the 1999 Plan. Corporate Transaction In the event of a Corporate Transaction (defined below), each outstanding option under the Discretionary Option Grant Program will vest and become exercisable for all the option shares as fully vested shares, unless that option is to be assumed by the successor corporation or to be replaced with a cash incentive program which preserves the existing option spread on the unvested option shares and provides for subsequent payout of that spread in accordance with the same vesting schedule for the shares. The Plan Administrator will have the discretion to structure one or more option grants under the Discretionary Option Grant Program so that those options will automatically vest in the event the individual's service is subsequently terminated within a specified period (not to exceed twelve (12) months) following a Corporate Transaction in which those options and shares do not otherwise vest on an accelerated basis. The Plan Administrator may also structure one or more option grants under the Discretionary Option Grant Program so that those options will automatically vest in full upon a Corporate Transaction. A Corporate Transaction includes any of the following shareholder-approved transactions: (i) a merger or acquisition in which the Company is not the surviving entity (other than a transaction the principal purpose of which is to change the state of the Company's incorporation), (ii) the sale, transfer or other disposition of all or substantially all of the Company's assets in complete liquidation or dissolution of the Company or (iii) any reverse merger in which the Company is the surviving entity but in which more than 50% of the Company's outstanding voting stock is transferred to the acquiring entity or its wholly owned subsidiary. 8

Change in Control The Plan Administrator will have the discretionary authority to provide for accelerated vesting of one or more outstanding options under the Discretionary Option Grant Program in connection with a Change in Control, with such accelerated vesting to occur either at the time of the Change in Control or upon the subsequent termination of the optionee's service. A Change in Control will be deemed to occur under the 1999 Plan upon: (i) the acquisition of more than 50% of the Company's outstanding voting stock pursuant to a tender or exchange offer made directly to the Company's shareholders or (ii) a change in the composition of the Board of Directors over a period of 36 months or less such that a majority of the Board members ceases, by reason of one or more proxy contests for the election of Board members, to be comprised of individuals who either (a) have been members of the Board continuously since the beginning of such period or (b) have been elected or nominated for election as Board members during such period by at least a majority of the Board members described in clause (a) who were still in office at the time such election or nomination was approved by the Board. The acceleration of vesting in the event of a change in the ownership or control of the Company may be seen as an anti-takeover provision and may have the effect of discouraging a merger proposal, a takeover attempt or other efforts to gain control of the Company. Special Tax Election The Plan Administrator may provide one or more holders of non-statutory options under the Discretionary Option Grant Program with the right to have the Company withhold a portion of the shares of Common Stock otherwise issuable to such individuals upon the exercise of those options or vesting of those shares in order to satisfy the Federal and state income and employment withholding taxes to which such individuals may become subject in connection with such exercise or vesting. Alternatively, the Plan Administrator may allow such individuals to deliver already existing shares of the Company's Common Stock in payment of such tax liability. Automatic Option Grant Program Under the Automatic Option Grant Program, non-employee Board members will receive option grants at specified intervals over their period of Board service. All grants under such program will be made in strict compliance with the express provisions of the program, and shareholder approval of this Proposal will also constitute pre-approval of each option granted on or after the date of the Annual Meeting pursuant to the amended provisions of the Automatic Option Grant Program summarized below and the subsequent exercise of that option in accordance with such provisions. On August 17, 2000, the Board amended the provisions of the Automatic Option Grant Program to decrease the number of shares of Common Stock for which option grants are to be made to new and continuing non-employee Board members under the Automatic Option Grant Program from 160,000 shares to 40,000 shares for the initial option grant made to each new non-employee Board member and from 40,000 shares to 15,000 shares for the annual option grant made to each continuing non-employee Board member. The proposed changes to the size of the option grants to be made to the non-employee Board members under the Automatic Option Grant Program are designed to maintain the competitiveness of the equity compensation package provided such individuals so that the Company will continue to have the ability to retain the services of highly-qualified and experienced non-employee Board members, while at the same time ensuring the size of those option grants do not, in light of the recent stock splits of the Company's Common Stock, substantially exceed the level of option grants made to non-employee board members at other companies in the industry. The Compensation Committee of the Board of Directors reviewed several surveys of non-employee director compensation, including the equity incentives provided those individuals. On the basis of that review, the Compensation Committee concluded that the decrease to the number of shares for which stock option grants are to be made to new and continuing non-employee Board members was reasonable and that the reduced size of the stock option grants would still remain at sufficiently large level to attract and retain skilled and talented non-employee Board members the Company seeks. 9

Under the amended Automatic Option Grant Program, each continuing non-employee Board member will on the date of each Annual Shareholders Meeting, beginning with the 2000 Annual Meeting, be granted an option to purchase 15,000 shares of Common Stock, provided such individual has served as a non-employee Board member for at least six months. Each individual who is first elected or appointed as a non-employee Board member at any time after the 2000 Annual Meeting will automatically be granted, at the time of such initial election or appointment, a non-statutory option to purchase 40,000 shares of Common Stock, provided such individual has not previously been in the employ of the Company. Each option grant under the Automatic Option Grant Program will have an exercise price per share equal to 100% of the fair market value per share of Common Stock on the grant date and a maximum term of 10 years measured from such date, subject to earlier termination upon the optionee's cessation of Board service. Each option will be immediately exercisable for the option shares. However, any shares purchased under the option will be subject to repurchase by the Company at the option exercise price paid per share, upon the Optionee's cessation of Board service prior to vesting in those shares. The shares subject to each initial 40,000-share automatic grant will vest in four (4) successive equal annual installments upon the optionee's completion of each year of Board service over the four (4)-year period measured from the grant date. The shares subject to each annual 15,000-share grant will vest upon the optionee's continuation in Board service through the day immediately preceding the next Annual Shareholders Meeting following the grant date of that option. The shares subject to each automatic option grant will immediately vest in full upon (i) the optionee's death or permanent disability while a Board member or (ii) the occurrence of a Corporate Transaction or Change in Control.

Amendment and Termination of the 1999 Plan The Board may amend or modify the 1999 Plan in any or all respects whatsoever subject to any shareholder approval required under applicable law or regulation. The Board may terminate the 1999 Plan at any time, but in no event will the 1999 Plan continue beyond August 16, 2009. Federal Tax Consequences Option Grants Options granted under the 1999 Plan may be either incentive stock options which satisfy the requirements of Section 422 of the Internal Revenue Code or non-statutory options which are not intended to satisfy such requirements. The Federal income tax treatment for the two types of options differs as follows: Incentive Stock Options No taxable income is recognized by the optionee at the time of the option grant, and no taxable income is generally recognized at the time the option is exercised. The optionee will, however, recognize taxable income in the year in which the purchased shares are sold or otherwise made the subject of disposition. For Federal income tax purposes, dispositions are divided into two categories: (i) qualifying and (ii) disqualifying. A qualifying disposition of the purchased shares will occur if the sale or disposition is made more than two years after the date the option for the shares was granted and more than one year after the date that the option was exercised for the particular shares involved in the sale or disposition. Unless both of those requirements are satisfied, a disqualifying disposition of the purchased shares will result. If the optionee makes a disqualifying disposition of the purchased shares, then the Company will be entitled to an income tax deduction, for the taxable year in which such disposition occurs, equal to the excess of (i) the fair market value of such shares on the date the option was exercised over (ii) the exercise price paid for such shares. In no other instance will the Company be allowed a deduction with respect to the optionee's disposition of the purchased shares. The Company anticipates that any compensation deemed paid by the Company upon one or more disqualifying dispositions of incentive stock option shares will not have to be taken into account for purposes of the $1 million limitation per covered individual on the deductibility of the compensation paid to certain executive officers of the Company. Non-Statutory Options No taxable income is recognized by an optionee upon the grant of a non-statutory option. The optionee will in general recognize ordinary income in the year in which the option is exercised equal to the excess of the fair market value of the purchased shares on the exercise date over the exercise price, and the optionee will be required to satisfy the tax withholding requirements applicable to such income. If the shares acquired upon exercise of a non-statutory option are subject to a substantial risk of forfeiture (such as the Company's right to repurchase unvested shares at the original exercise price paid per share, upon the optionee's cessation of service prior to vesting in those shares), then the optionee will not recognize any taxable income at the time the option is exercised for such unvested shares but will have to report as ordinary income, as the shares vest, an amount equal to the excess of (a) the fair market value of the shares on the vesting date over (b) the exercise price paid for the shares. The optionee may, however, elect under Section 83(b) of the Internal Revenue Code to include as ordinary income in the year of exercise an amount equal to the amount by which the fair market value of the purchased shares on the date of exercise (determined as if the unvested shares were not subject to the Company's repurchase right) exceeds the exercise price paid for those shares. If the Section 83(b) election is made, the optionee will not recognize any additional income as and when the shares vest. The Company will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the optionee in connection with the exercise of the non-statutory option. The deduction will in general be allowed for the taxable year of the Company in which such ordinary income is recognized by the optionee. The Company anticipates that the compensation deemed paid by the Company upon the exercise of non-statutory options will not have to be taken into account for purposes of the $1 million limitation per covered individual on the deductibility of the compensation paid to certain executive officers of the Company. 11

Accounting Treatment Under current accounting rules, option grants to employees with an exercise price equal to the fair market value of the shares on the grant date will not result in a direct compensation expense to the Company's earnings. However, the fair value of those options and the related pro-forma net income or loss are required to be disclosed in the notes to the Company's consolidated financial statements. In addition, the number of outstanding options may be a factor in determining the Company's earnings per share on a diluted basis. Option grants made to independent consultants (but not non-employee Board members) will result in a direct charge to the Company's reported earnings based upon the fair value of the option measured initially as of the grant date of that option and then subsequently on the vesting date of each installment of the underlying option shares. Such charge will accordingly include the appreciation in the value of the option shares over the period between the grant date of the option and the vesting date of each installment of the option shares. Under Financial Accounting Standards Board Interpretation No. 44, any options which are repriced after December 15, 1998 will also trigger a direct charge to the Company's reported earnings measured by the appreciation in value of the underlying shares between the grant date of the option (or, if later, the July 1, 2000 effective date of the Interpretation) and the date the option is exercised for those shares. New Plan Benefits As of May 31, 2000, no options have been granted on the basis of the 15,000,000-share increase that is the subject of this Proposal. If the Proposal is approved by the shareholders at the Annual Meeting, then each individual who will continue to serve as a non-employee Board member will, on the date of the Annual Meeting, receive an option grant under the Automatic Option Grant Program to purchase 15,000 shares of Common Stock with an exercise price per share equal to the closing selling price per share of Common Stock on that date. Shareholder Approval The affirmative vote of a majority of the shares represented and voting at the Annual Meeting, together with the affirmative vote of the majority of the required quorum, is required for approval of the proposed 15,000,000-share increase to the 1999 Plan. If shareholder approval is not obtained, then any options granted on the basis of the 15,000,000-share increase will terminate without becoming exercisable for any of the shares of Common Stock subject to those options, and no further options will be granted on the basis of such share increase. However, the 1999 Plan will continue to remain in effect, and option grants may continue to be made pursuant to the provisions of the 1999 Plan as in effect prior to the proposed 15,000,000-share increase, until the available reserve of Common Stock as last approved by the shareholders has been issued pursuant to option grants made under the 1999 Plan. Recommendation of the Board of Directors The Board of Directors believes that the proposed share increase to the 1999 Plan is necessary in order to continue to provide equity incentives to attract and retain the services of key employees, consultants and non-employee Board members. For this reason, the Board of Directors recommends that the shareholders vote FOR the proposal to approve the additional 15,000,000-share increase to the 1999 Plan. PROPOSAL NO. 3: RATIFICATION OF INDEPENDENT PUBLIC ACCOUNTANTS The Company is asking the shareholders to ratify the selection of Deloitte and Touche LLP as the Company's independent public accountants for the fiscal year ending April 27, 2001. The affirmative vote of a majority of the outstanding voting shares of the Company present or represented and voting at the Annual Meeting, together with the affirmative vote of the majority of the required quorum, will be required to ratify the selection of Deloitte and Touche LLP. 12

In the event the shareholders fail to ratify the appointment, the Audit Committee of the Board of Directors will consider it as a direction to select other auditors for the subsequent year. Even if the selection is ratified, the Board in its discretion may direct the appointment of a different independent accounting firm at any time during the year if the Board determines that such a change would be in the best interest of the Company and its shareholders. A representative of Deloitte and Touche LLP is expected to be present at the Annual Meeting, will have the opportunity to make a statement if he or she desires to do so, and will be available to respond to appropriate questions. The Board of Directors recommends that shareholders vote FOR the proposal to ratify the selection of Deloitte and Touche LLP as the Company's independent public accountants for the fiscal year ending April 27, 2001.

Section 16(a) Beneficial Ownership Reporting Compliance Section 16(a) of the Securities and Exchange Act of 1934 requires the Company's directors and executive officers and persons who own more than ten percent (10%) of a registered class of the Company's equity securities, to file with the Securities and Exchange Commission (the "SEC") initial reports of ownership and reports of changes in ownership of Common Stock and other equity securities of the Company. Officers, directors and greater than ten percent (10%) shareholders are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms they file. 14

Based solely upon review of the copies of such reports furnished to the Company and written representations that no other reports were required, the Company believes that during the fiscal year ended April 28, 2000, its officers, directors and holders of more than 10% of the Company's Common Stock complied with all Section 16(a) filing requirements, except that a Form 3 filing by Dr. Semmoto was filed late.

REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION The Compensation Committee of the Board of Directors (the "Committee") is currently comprised of two non-employee directors, Carol A. Bartz and Robert T. Wall, and was formed in November of 1995, in anticipation of the initial public offering of the Company's Common Stock. For the 2000 fiscal year, all compensation decisions with respect to base salaries and bonuses for the Company's executive officers were made by the Compensation Committee. The Committee made its decisions primarily on the basis of the Committee's understanding of the compensation practices of similarly-sized companies in the industry and fixed the compensation package of each executive officer at a level which was competitive with those practices. The Committee administers the Company's compensation policies and programs and has primary responsibility for executive compensation matters, including the establishment of the base salaries of the Company's executive officers, the approval of individual bonuses and bonus programs for executive officers and the administration of certain employee benefit programs. In addition, the Committee has exclusive responsibility for administering the Company's 1999 Plan, under which stock option grants and direct stock issuances may be made to executive officers and other employees. The following is a summary of policies which the Committee applies in setting the compensation levels for the Company's executive officers. General Compensation Policy. The overall policy of the Committee is to offer the Company's executive officers competitive compensation opportunities based upon their personal performance, the financial performance of the Company and their contribution to that performance. One of the primary objectives is to have a substantial portion of each executive officer's compensation contingent upon the Company's financial success as well as upon such executive officer's own level of performance. Each executive officer's compensation package is comprised of three elements: (i) base salary, which is determined on the basis of the individual's position and responsibilities with the Company, the level of his or her performance and competitive salary levels, (ii) incentive performance awards payable in cash and based upon a formula which takes into account Company and individual performance and (iii) long-term stock-based incentive awards designed to strengthen the mutuality of interests between the executive officers and the Company's shareholders. Generally, as an executive officer's level of responsibility increases, a greater portion of that individual's total compensation becomes dependent upon the Company's performance and stock price appreciation rather than base salary. Factors. The primary factors taken into consideration in establishing the components of each executive officer's compensation package for the 2000 fiscal year are summarized below. However, the Committee may, in its discretion, apply entirely different factors, such as different measures of financial performance, for future fiscal years. Base Salary. In setting the base salary for each executive officer, the Committee reviews published compensation survey data for its industry. The base salary for each officer is designed to be competitive with the salary levels for comparable positions in the published surveys as well as to reflect the individual's personal performance and internal alignment considerations. The relative weight given to each factor varies with each individual in the sole discretion of the Committee. For the 2000 fiscal year, the base salary of the Company's executive officers ranged from the fiftieth percentile to the sixty-fifth percentile of the base salary levels in effect for comparable positions in the surveyed compensation data. Incentive Compensation. For the 2000 fiscal year, an incentive compensation program was established pursuant to which each executive officer earned a bonus on the basis of the Company's achievement of certain operating income objectives and his or her individual performance. The bonus amount was tied to a percentage of each executive officer's base salary and was earned on the basis of the Company's actual financial performance in comparison to the Company's business plan as measured in terms of operating income, with additional consideration given to the attainment of individual goals. However, no bonus would have been earned if the Company's actual operating income had been less than 50% of the plan. The Company's financial performance exceeded the plan and, accordingly, the executive officers were awarded the bonuses indicated for them in the Summary Compensation Table which appears earlier in this Proxy Statement. 18

Long-Term Stock-Based Incentive Compensation. From time to time, the Committee makes option grants to the Company's executive officers under the 1999 Plan. The grants are designed to align the interests of each executive officer with those of the shareholders and provide each individual with a significant incentive to manage the Company from the perspective of an owner with an equity stake in the business. Each grant allows the officer to acquire shares of the Company's Common Stock at a fixed price per share (the market price on the grant date) over a specified period of time (up to ten (10) years), thus providing a return to the executive officer only if the market price of the shares appreciates over the option term and the officer continues in the Company's employ. The size of the option grant to each executive officer is designed to create a meaningful opportunity for stock ownership and is based upon the executive officer's current position with the Company, internal comparability with option grants made to other Company executives, the executive officer's current level of performance and the executive officer's potential for future responsibility and promotion over the option term. The Committee also takes into account the number of vested and unvested options held by the executive officer in order to maintain an appropriate level of equity incentive for that individual. However, the Committee does not intend to adhere to any specific guidelines as to the relative option holdings of the Company's executive officers. CEO Compensation. The compensation payable to Mr. Warmenhoven, the Company's Chief Executive Officer during fiscal year 2000, was determined by the Compensation Committee. His base salary was set at a level which the Committee felt would be competitive with the base salary levels in effect for chief executive officers at similarly-sized companies within the industry and was at approximately the fiftieth percentile of the published surveys. Based upon the Committee's evaluation of the Company's achievement of certain performance goals tied to operating income and Mr. Warmenhoven's individual performance, the Committee awarded Mr. Warmenhoven a bonus of $397,961 for the 2000 fiscal year. The options granted to Mr. Warmenhoven during the 2000 fiscal year were in recognition of his personal performance and leadership role with the Company and were intended to place a significant portion of his total compensation at risk because the value of those grants will depend upon the future appreciation of the Company's Common Stock. Compliance With Internal Revenue Code Section 162(m). Section 162(m) of the Internal Revenue Code, enacted in 1993, generally disallows a tax deduction to publicly-held companies for compensation paid to certain executive officers, to the extent that compensation exceeds $1 million per officer in any year. The compensation paid to the Company's executive officers for the 2000 fiscal year did not exceed the $1 million limit per officer, and it is not expected the compensation to be paid to the Company's executive officers for the 2001 fiscal year will exceed that limit. In addition, the 1995 Plan and 1999 Plan are structured so that any compensation deemed paid to an executive officer in connection with the exercise of his or her outstanding options under each such plan will qualify as performance-based compensation which will not be subject to the $1 million limitation. Because it is very unlikely that the cash compensation payable to any of the Company's executive officers in the foreseeable future will approach the $1 million limit, the Committee has decided at this time not to take any other action to limit or restructure the elements of cash compensation payable to the Company's executive officers. The Committee will reconsider this decision should the individual compensation of any executive officer ever approach the $1 million level. Submitted by the Compensation Committee of the Board of Directors: CAROL A. BARTZ ROBERT T. WALL 19

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION The Compensation Committee of the Company's Board of Directors is comprised of Ms. Bartz and Mr. Wall. Neither of these individuals was at any time during the 2000 fiscal year, or at any other time, an officer or employee of the Company. No executive officer of the Company serves as a member of the board of directors or compensation committee of any entity which has one or more executive officers serving as a member of the Company's Board of Directors or Compensation Committee. EMPLOYMENT CONTRACTS, TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL AGREEMENTS The Company does not presently have any employment contracts in effect with the Chief Executive Officer or any of the other executive officers named in the Summary Compensation Table. The options granted to Daniel J. Warmenhoven, Chief Executive Officer, under the Company's 1993 Stock Option/Stock Issuance Plan, the 1995 Stock Incentive Plan and the 1999 Stock Option Plan, to Jeffry R. Allen, Chief Financial Officer and Executive Vice President and to Thomas F. Mendoza, President, under the 1995 Stock Incentive Plan and the 1999 Stock Option Plan, will immediately vest in full in the event of their termination of employment in connection with an acquisition of the Company by merger or asset sale. The options granted to Messrs. Warmenhoven, Allen and Mendoza on January 4, 1999 and January 3, 2000 under the Salary Investment Option Grant Program of the 1995 Plan will immediately accelerate in full upon an acquisition of the Company by merger or asset sale or other change in control of the Company. In addition, each outstanding option held by the Chief Executive Officer, the other executive officers and the employees of the Company under the Discretionary Option Grant Program of the 1995 Plan or the 1999 Plan will automatically accelerate in full, and all unvested shares of Common Stock held by such individuals under the 1995 Plan or the 1999 Plan will immediately vest in full, upon an acquisition of the Company by merger or asset sale, except to the extent such options are to be assumed by, and the Company's repurchase rights with respect to those shares are to be assigned to, the successor corporation. In addition, the Compensation Committee as Plan Administrator of the 1995 Plan and the 1999 Plan will have the authority to provide for the accelerated vesting of the shares of Common Stock subject to outstanding options held by the Chief Executive Officer or any other executive officer, and the shares of Common Stock subject to direct issuances held by such individual, in connection with the termination of the officer's employment following (i) a merger or asset sale in which those options are assumed and the Company's repurchase rights with respect to unvested shares are assigned, or (ii) certain other changes in control or ownership of the Company.

PURPOSE OF THE PLAN This 1999 Stock Option Plan is intended to promote the interests of Network Appliance, Inc., a California corporation, by providing eligible persons with the opportunity to acquire a proprietary interest, or otherwise increase their proprietary interest, in the Corporation as an incentive for them to remain in the service of the Corporation. Capitalized terms shall have the meanings assigned to such terms in the attached Appendix. All share numbers in the document reflect (i) the 2-for-1 split of the Common Stock effected on December 20, 1999 and (ii) the 2-for-1 split of the Common Stock effected on March 22, 2000. II. STRUCTURE OF THE PLAN A. The Plan shall be divided into two separate equity programs: (i) the Discretionary Option Grant Program under which eligible persons may, at the discretion of the Plan Administrator, be granted options to purchase shares of Common Stock, and (ii) the Automatic Option Grant Program under which non-employee Board members shall automatically receive option grants at periodic intervals to purchase shares of Common Stock. B. The provisions of Articles One and Four shall apply to all equity programs under the Plan and shall accordingly govern the interests of all persons under the Plan. III.

Members of the Primary Committee or any Secondary Committee shall serve for such period of time as the Board may determine and may be removed by the Board at any time. The Board may also at any time terminate the functions of any Secondary Committee and reassume all powers and authority previously delegated to such committee. C. Each Plan Administrator shall, within the scope of its administrative functions under the Plan, have full power and authority to establish such rules and regulations as it may deem appropriate for proper administration of the Discretionary Option Grant Program and to make such determinations under, and issue such interpretations of, the provisions of such programs and any outstanding options thereunder as it may deem necessary or advisable. Decisions of the Plan Administrator within the scope of its administrative functions under the Plan shall be final and binding on all parties who have an interest in the Discretionary Option Grant Program under its jurisdiction or any stock option thereunder. D. Service on the Primary Committee or the Secondary Committee shall constitute service as a Board member, and members of each such committee shall accordingly be entitled to full indemnification and reimbursement as Board members for their service on such committee. No member of the Primary Committee or the Secondary Committee shall be liable for any act or omission made in good faith with respect to the Plan or any option grants under the Plan. E. Administration of the Automatic Option Grant Program shall be self-executing in accordance with the terms of that program, and no Plan Administrator shall exercise any discretionary functions with respect to option grants made thereunder. IV. ELIGIBILITY A. The persons eligible to participate in the Discretionary Option Grant Program are as follows: (i) Employees, and (ii) consultants and other independent advisors who provide services to the Corporation (or any Parent or Subsidiary). B. Each Plan Administrator shall, within the scope of its administrative jurisdiction under the Plan, have full authority (subject to the provisions of the Plan) to determine which eligible persons are to receive option grants under the Discretionary Option Grant Program, the time or times when such option grants are to be made, the number of shares to be covered by each such grant, the status of the granted option as either an Incentive Option or a Non-Statutory Option, the time or times when each option is to become exercisable, the vesting schedule (if any) applicable to the option shares and the maximum term for which the option is to remain outstanding. 2

C. Only non-employee Board members shall be eligible to participate in the Automatic Option Grant Program. V. STOCK SUBJECT TO THE PLAN A. The stock issuable under the Plan shall be shares of authorized but unissued or reacquired Common Stock, including shares repurchased by the Corporation on the open market. The maximum number of shares of Common Stock which may be issued over the term of the Plan shall not exceed 28,200,000 shares. Such authorized share reserve is comprised of (i) the 13,200,000 shares of Common Stock initially authorized for issuance under the Plan plus (ii) an additional increase of 15,000,000 shares authorized by the Board on August 17, 2000, subject to shareholder approval at the 2000 Annual Meeting. Such authorized share reserve shall be in addition to the number of shares of Common Stock reserved for issuance under the Corporation's 1995 Stock Incentive Plan and the Corporation's Special Non-Officer Stock Option Plan, and share issuances under this Plan shall not reduce or otherwise affect the number of shares of Common Stock available for issuance under the 1995 Stock Incentive Plan or the Special Non-Officer Stock Option Plan. In addition, share issuances under such plans shall not reduce or otherwise affect the number of shares of Common Stock available for issuance under this Plan. B. No one person participating in the Plan may receive stock options under the Plan for more than 3,000,000 shares of Common Stock in the aggregate per calendar year. Before the split of the Common Stock which occurred in March 2000. such limit was 1,500,000 shares. C. Shares of Common Stock subject to outstanding options shall be available for subsequent issuance under the Plan to the extent (i) the options expire or terminate for any reason prior to exercise in full or (ii) the options are cancelled in accordance with the cancellation/regrant provisions of Article Two. In addition, any unvested shares issued under the Plan and subsequently repurchased by the Corporation, at the option exercise price paid per share, pursuant to the Corporation's repurchase rights under the Plan shall be added back to the number of shares of Common Stock reserved for issuance under the Plan and shall accordingly be available for reissuance through one or more subsequent option grants under the Plan. Should the exercise price of an option under the Plan be paid with shares of Common Stock or should shares of Common Stock otherwise issuable under the Plan be withheld by the Corporation in satisfaction of the withholding taxes incurred in connection with the exercise of an option or the vesting of exercised option shares under the Plan, then the number of shares of Common Stock available for issuance under the Plan shall be reduced by the gross number of shares for which the option is exercised or the gross number of exercised option shares which vest, and not by the net number of shares of Common Stock issued to the holder of such option or exercised option shares. 3

D. Should any change be made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation's receipt of consideration, appropriate adjustments shall be made to (i) the maximum number and/or class of securities issuable under the Plan, (ii) the maximum number and/or class of securities for which any one person may be granted stock options per calendar year, (iii) the number and/or class of securities for which automatic option grants are to be made subsequently under the Automatic Option Grant Program and (iv) the number and/or class of securities and the exercise price per share in effect under each outstanding option in order to prevent the dilution or enlargement of benefits thereunder. The adjustments determined by the Plan Administrator shall be final, binding and conclusive. 4

ARTICLE TWO DISCRETIONARY OPTION GRANT PROGRAM I. OPTION TERMS Each option shall be evidenced by one or more documents in the form approved by the Plan Administrator; provided, however, that each such document shall comply with the terms specified below. Each document evidencing an Incentive Option shall, in addition, be subject to the provisions of the Plan applicable to such options. A. Exercise Price. 1. The exercise price per share shall be fixed by the Plan Administrator but shall not be less than one hundred percent (100%) of the Fair Market Value per share of Common Stock on the option grant date. 2. The exercise price shall become immediately due upon exercise of the option and shall be payable in one or more of the forms specified below: (i) cash or check made payable to the Corporation, (ii) shares of Common Stock held for the requisite period necessary to avoid a charge to the Corporation's earnings for financial reporting purposes and valued at Fair Market Value on the Exercise Date, or (iii) to the extent the option is exercised for vested shares, through a special sale and remittance procedure pursuant to which the Optionee shall concurrently provide irrevocable instructions to (a) a Corporation-designated brokerage firm to effect the immediate sale of the purchased shares and remit to the Corporation, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate exercise price payable for the purchased shares plus all applicable Federal, state and local income and employment taxes required to be withheld by the Corporation by reason of such exercise and (b) the Corporation to deliver the certificates for the purchased shares directly to such brokerage firm in order to complete the sale transaction. Except to the extent such sale and remittance procedure is utilized, payment of the exercise price for the purchased shares must be made on the Exercise Date. B. Exercise and Term of Options. Each option shall be exercisable at such time or times, during such period and for such number of shares as shall be determined by the Plan Administrator and set forth in the documents evidencing the option. However, no option shall have a term in excess of ten (10) years measured from the option grant date. 5

C. Effect of Termination of Service. 1. The following provisions shall govern the exercise of any options held by the Optionee at the time of cessation of Service or death: (i) Any option outstanding at the time of the Optionee's cessation of Service for any reason shall remain exercisable for such period of time thereafter as shall be determined by the Plan Administrator and set forth in the documents evidencing the option, but no such option shall be exercisable after the expiration of the option term. (ii) Any option exercisable in whole or in part by the Optionee at the time of death may be exercised subsequently by the personal representative of the Optionee's estate or by the person or persons to whom the option is transferred pursuant to the Optionee's will or in accordance with the laws of descent and distribution. (iii) During the applicable post-Service exercise period, the option may not be exercised in the aggregate for more than the number of vested shares for which the option is exercisable on the date of the Optionee's cessation of Service. Upon the expiration of the applicable exercise period or (if earlier) upon the expiration of the option term, the option shall terminate and cease to be outstanding for any vested shares for which the option has not been exercised. However, the option shall, immediately upon the Optionee's cessation of Service, terminate and cease to be outstanding to the extent the option is not otherwise at that time exercisable for vested shares. (iv) Should the Optionee's Service be terminated for Misconduct, then all outstanding options held by the Optionee shall terminate immediately and cease to be outstanding. 2. The Plan Administrator shall have the discretion, exercisable either at the time an option is granted or at any time while the option remains outstanding, to: (i) extend the period of time for which the option is to remain exercisable following the Optionee's cessation of Service from the period otherwise in effect for that option to such greater period of time as the Plan Administrator shall deem appropriate, but in no event beyond the expiration of the option term, and/or (ii) permit the option to be exercised, during the applicable post-Service exercise period, not only with respect to the number of vested shares of Common Stock for which such option is exercisable at the time of the Optionee's cessation of Service but also with respect to one or more additional installments in which the Optionee would have vested under the option had the Optionee continued in Service. D. Shareholder Rights. The holder of an option shall have no shareholder rights with respect to the shares subject to the option until such person shall have exercised the option, paid the exercise price and become a holder of record of the purchased shares. 6

E. Repurchase Rights. The Plan Administrator shall have the discretion to grant options which are exercisable for unvested shares of Common Stock. Should the Optionee cease Service while holding such unvested shares, the Corporation shall have the right to repurchase, at the exercise price paid per share, any or all of those unvested shares. The terms upon which such repurchase right shall be exercisable (including the period and procedure for exercise and the appropriate vesting schedule for the purchased shares) shall be established by the Plan Administrator and set forth in the document evidencing such repurchase right. F. Limited Transferability of Options. During the lifetime of the Optionee, Incentive Options shall be exercisable only by the Optionee and shall not be assignable or transferable other than by will or by the laws of inheritance following the Optionee's death. However, Non-Statutory Options may be assigned in whole or in part during the Optionee's lifetime to one or more members of the Optionee's family or to a trust established exclusively for one or more such family members or the Optionee's former spouse, to the extent such assignment is in connection with the Optionee's estate plan, or to the Optionee's former spouse pursuant to a domestic relations order. The assigned portion may only be exercised by the person or persons who acquire a proprietary interest in the option pursuant to the assignment. The terms applicable to the assigned portion shall be the same as those in effect for the option immediately prior to such assignment and shall be set forth in such documents issued to the assignee as the Plan Administrator may deem appropriate. II. INCENTIVE OPTIONS The terms specified below shall be applicable to all Incentive Options. Except as modified by the provisions of this Section II, all the provisions of Articles One, Two and Four shall be applicable to Incentive Options. Options which are specifically designated as Non-Statutory Options when issued under the Plan shall not be subject to the terms of this Section II. A. Eligibility. Incentive Options may only be granted to Employees. B. Dollar Limitation. The aggregate Fair Market Value of the shares of Common Stock (determined as of the respective date or dates of grant) for which one or more options granted to any Employee under the Plan (or any other option plan of the Corporation or any Parent or Subsidiary) may for the first time become exercisable as Incentive Options during any one (1) calendar year shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the Employee holds two (2) or more such options which become exercisable for the first time in the same calendar year, the foregoing limitation on the exercisability of such options as Incentive Options shall be applied on the basis of the order in which such options are granted. C. 10% Shareholder. If any Employee to whom an Incentive Option is granted is a 10% Shareholder, then the exercise price per share shall not be less than one hundred ten percent (110%) of the Fair Market Value per share of Common Stock on the option grant date, and the option term shall not exceed five (5) years measured from the option grant date. 7

III. CORPORATE TRANSACTION/CHANGE IN CONTROL A. Each option, to the extent outstanding under the Plan at the time of a Corporate Transaction but not otherwise exercisable for all the option shares, shall automatically accelerate so that each such option shall, immediately prior to the effective date of the Corporate Transaction, become exercisable for all of the shares of Common Stock at the time subject to such option and may be exercised for any or all of those shares as fully-vested shares of Common Stock. However, an outstanding option shall not become exercisable on such an accelerated basis if and to the extent: (i) such option is, in connection with the Corporate Transaction, to be assumed by the successor corporation (or parent thereof) or replaced with a comparable option to purchase shares of the capital stock of the successor corporation (or parent thereof), (ii) such option is to be replaced with a cash incentive program of the successor corporation which preserves the spread existing on the unvested option shares at the time of the Corporate Transaction and provides for subsequent payout in accordance with the same vesting schedule applicable to those option shares or (iii) the acceleration of such option is subject to other limitations imposed by the Plan Administrator at the time of the option grant. The determination of option comparability under clause (i) above shall be made by the Plan Administrator, and its determination shall be final, binding and conclusive. B. All outstanding repurchase rights shall also terminate automatically, and the shares of Common Stock subject to those terminated rights shall immediately vest in full, in the event of any Corporate Transaction, except to the extent: (i) those repurchase rights are to be assigned to the successor corporation (or parent thereof) in connection with such Corporate Transaction or (ii) such accelerated vesting is precluded by other limitations imposed by the Plan Administrator at the time the repurchase right is issued. C. Immediately following the consummation of the Corporate Transaction, all outstanding options shall terminate and cease to be outstanding, except to the extent assumed by the successor corporation (or parent thereof). D. Each option which is assumed in connection with a Corporate Transaction shall be appropriately adjusted, immediately after such Corporate Transaction, to apply to the number and class of securities which would have been issuable to the Optionee in consummation of such Corporate Transaction had the option been exercised immediately prior to such Corporate Transaction. Appropriate adjustments to reflect such Corporate Transaction shall also be made to (i) the exercise price payable per share under each outstanding option, provided the aggregate exercise price payable for such securities shall remain the same, (ii) the maximum number and/or class of securities available for issuance over the remaining term of the Plan and (iii) the maximum number and/or class of securities for which any one person may be granted stock options under the Plan per calendar year. E. The Plan Administrator shall have full power and authority to grant options under the Plan which will automatically accelerate in whole or in part in the event the Optionee's Service subsequently terminates by reason of an Involuntary Termination within a designated period (not to exceed twelve (12) months) following the effective date of any Corporate Transaction in which those options are assumed or replaced and do not otherwise accelerate. Any options so accelerated shall remain exercisable for fully-vested shares until the 8

earlier of (i) the expiration of the option term or (ii) the expiration of the one (1)-year period measured from the effective date of the Involuntary Termination. In addition, the Plan Administrator may provide that one or more of the Corporation's outstanding repurchase rights with respect to shares held by the Optionee at the time of such Involuntary Termination shall immediately terminate in whole or in part, and the shares subject to those terminated rights shall accordingly vest at that time. F. The Plan Administrator shall have full power and authority to grant options under the Plan which will automatically accelerate in whole or in part in the event the Optionee's Service subsequently terminates by reason of an Involuntary Termination within a designated period (not to exceed twelve (12) months) following the effective date of any Change in Control. Each option so accelerated shall remain exercisable for fully-vested shares until the earlier of (i) the expiration of the option term or (ii) the expiration of the one (1)-year period measured from the effective date of the Involuntary Termination. In addition, the Plan Administrator may provide that one or more of the Corporation's outstanding repurchase rights with respect to shares held by the Optionee at the time of such Involuntary Termination shall immediately terminate in whole or in part, and the shares subject to those terminated rights shall accordingly vest at that time. G. The portion of any Incentive Option accelerated in connection with a Corporate Transaction or Change in Control shall remain exercisable as an Incentive Option only to the extent the applicable One Hundred Thousand Dollar limitation is not exceeded. To the extent such dollar limitation is exceeded, the accelerated portion of such option shall be exercisable as a Non-Qualified Option under the Federal tax laws. H. The outstanding options shall in no way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. IV. CANCELLATION AND REGRANT OF OPTIONS The Plan Administrator shall have the authority to effect, at any time and from time to time, with the consent of the affected option holders, the cancellation of any or all outstanding options under the Plan and to grant in substitution new options covering the same or different number of shares of Common Stock but with an exercise price per share based on the Fair Market Value per share of Common Stock on the new grant date. However, any such option cancellation/regrant program shall be subject to the following two limitations: (i) only options held by Employees who are neither executive officers of the Corporation nor members of the Board may be so cancelled and regranted; and (ii) the total number of shares subject to options which are so cancelled and regranted from time to time pursuant to this Section IV shall not in the aggregate exceed ten percent (10%) of the total number of shares of Common Stock authorized for issuance under the Plan. 9

ARTICLE THREE AUTOMATIC OPTION GRANT PROGRAM The following provisions reflect the changes to the Automatic Option Grant Program approved by the Board on August 17, 2000 to be effective as of the 2000 Annual Shareholders Meeting. The Board reduced the number of shares of Common Stock for which option grants are to be made to new and continuing non-employee Board members under the Automatic Option Grant Program from 160,000 shares (as adjusted to reflect the two splits of the Common Stock which have occurred since the implementation of the Plan) to 40,000 shares for each new non-employee Board member and from 40,000 shares (as adjusted to reflect the two splits of the Common Stock which have occurred since the implementation of the Plan) to 15,000 shares for each continuing non-employee Board member. I. OPTION TERMS A. Grant Dates. Option grants shall be made on the dates specified below: 1. Each individual who is first elected or appointed as a non-employee Board member on or after the date of the 2000 Annual Shareholders Meeting shall automatically be granted, on the date of such initial election or appointment, a Non-Statutory Option to purchase 40,000 shares of Common Stock, provided such individual has not previously been in the employ of the Corporation (or any Parent or Subsidiary). 2. On the date of each Annual Shareholders Meeting, beginning with the 2000 Annual Meeting, each individual who is to continue to serve as a non-employee Board member shall automatically be granted a Non-Statutory Option to purchase 15,000 shares of Common Stock, provided such individual has served as a non-employee Board member for at least six (6) months. There shall be no limit on the number of such 15,000-share option grants any one non-employee Board member may receive over his or her period of Board service. 3. Shareholder approval of the 15,000,000-share increase to the Plan at the 2000 Annual Shareholders Meeting shall constitute pre-approval of each option grant made under this Automatic Option Grant Program on or after the date of that Annual Meeting and the subsequent exercise of that option in accordance with the terms and conditions of this Article Three and the stock option agreement evidencing such grant. 4. The Automatic Option Grant Program under this Plan supersedes and replaces the Automatic Option Grant Program previously in effect for the non-employee Board members under the Corporation's 1995 Stock Incentive Plan. That latter program terminated upon shareholder approval of the Plan at the 1999 Annual Shareholders Meeting, and no further option grants shall be made to the non-employee Board members under that program. 10

All options granted to the non-employee Board members on or after the date of the 1999 Annual Shareholders Meeting, whether upon their initial election or appointment to the Board or upon their re-election at one or more of the Corporation's subsequent Annual Shareholder Meetings, shall be effected solely and exclusively in accordance with the terms and provisions of this Article Three, as in effect from time to time. B. Exercise Price. 1. The exercise price per share shall be equal to one hundred percent (100%) of the Fair Market Value per share of Common Stock on the option grant date. 2. The exercise price shall be payable in one or more of the alternative forms authorized under the Discretionary Option Grant Program. Except to the extent the sale and remittance procedure specified thereunder is utilized, payment of the exercise price for the purchased shares must be made on the Exercise Date. C. Option Term. Each option shall have a term of ten (10) years measured from the option grant date. D. Exercise and Vesting of Options. Each option shall be immediately exercisable for any or all of the option shares. However, any shares purchased under the option shall be subject to repurchase by the Corporation, at the exercise price paid per share, upon the Optionee's cessation of Board service prior to vesting in those shares. Each initial 40,000-share grant shall vest, and the Corporation's repurchase right shall lapse, in a series of four (4) successive equal annual installments over the Optionee's period of continued service as a Board member, with the first such installment to vest upon the Optionee's completion of one (1) year of Board service measured from the option grant date. Each annual 15,000-share grant shall vest, and the Corporation's repurchase right shall lapse, upon the Optionee's continuation in Board service through the day immediately preceding the next Annual Shareholders Meeting following the option grant date. E. Effect of Termination of Board Service. The following provisions shall govern the exercise of any options held by the Optionee at the time the Optionee ceases to serve as a Board member: (i) The Optionee (or, in the event of the Optionee's death, the personal representative of the Optionee's estate or the person or persons to whom the option is transferred pursuant to the Optionee's will or in accordance with the laws of descent and distribution) shall have a twelve (12)-month period following the date of such cessation of Board service in which to exercise each such option. (ii) During the twelve (12)-month exercise period, the option may not be exercised in the aggregate for more than the number of vested shares of Common Stock for which the option is exercisable at the time of the Optionee's cessation of Board service. 11

(iii) Should the Optionee cease to serve as a Board member by reason of death or Permanent Disability, then all shares at the time subject to the option shall immediately vest so that such option may, during the twelve (12)-month exercise period following such cessation of Board service, be exercised for all or any portion of those shares as fully-vested shares of Common Stock. (iv) In no event shall the option remain exercisable after the expiration of the option term. Upon the expiration of the twelve (12)-month exercise period or (if earlier) upon the expiration of the option term, the option shall terminate and cease to be outstanding for any vested shares for which the option has not been exercised. However, the option shall, immediately upon the Optionee's cessation of Board service for any reason other than death or Permanent Disability, terminate and cease to be outstanding to the extent the option is not otherwise at that time exercisable for vested shares. II. CORPORATE TRANSACTION/CHANGE IN CONTROL A. The shares of Common Stock subject to each outstanding option at the time of a Corporate Transaction but not otherwise vested shall automatically vest in full so that each such option shall, immediately prior to the effective date of that Corporate Transaction, become fully exercisable for all of the shares of Common Stock at the time subject to such option and may be exercised for all or any portion of those shares as fully-vested shares of Common Stock. Immediately following the consummation of the Corporate Transaction, each automatic option grant shall terminate and cease to be outstanding, except to the extent assumed by the successor corporation (or parent thereof). B. The shares of Common Stock subject to each outstanding option at the time of a Change in Control but not otherwise vested shall automatically vest in full so that each such option shall, immediately prior to the effective date of that Change in Control, become fully exercisable for all of the shares of Common Stock at the time subject to such option and may be exercised for all or any portion of those shares as fully-vested shares of Common Stock. Each such option shall remain exercisable for such fully-vested option shares until the expiration or sooner termination of the option term. C. All repurchase rights of the Corporation outstanding under the Automatic Option Grant Program at the time of a Corporate Transaction or Change in Control shall automatically terminate at that time, and the shares of Common Stock subject to those terminated rights shall immediately vest. D. Each option which is assumed in connection with a Corporate Transaction shall be appropriately adjusted, immediately after such Corporate Transaction, to apply to the number and class of securities which would have been issuable to the Optionee in consummation of such Corporate Transaction had the option been exercised immediately prior to such Corporate Transaction. Appropriate adjustments shall also be made to the exercise price payable per share under each outstanding option, provided the aggregate exercise price payable for such securities shall remain the same. 12

E. The grant of options under the Automatic Option Grant Program shall in no way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. III. REMAINING TERMS The remaining terms of each option granted under the Automatic Option Grant Program shall be the same as the terms in effect for option grants made under the Discretionary Option Grant Program. 13

ARTICLE FOUR MISCELLANEOUS I. TAX WITHHOLDING A. The Corporation's obligation to deliver shares of Common Stock upon the exercise of stock options or the issuance or vesting of such shares under the Plan shall be subject to the satisfaction of all applicable Federal, state and local income and employment tax withholding requirements. B. The Plan Administrator may, in its discretion, provide any or all holders of Non-Statutory Options or unvested shares of Common Stock under the Plan (other than the options granted or the shares issued under the Automatic Option Grant Program) with the right to use shares of Common Stock in satisfaction of all or part of the Withholding Taxes to which such holders become subject in connection with the exercise of their options or the vesting of their shares. Such right may be provided to any such holder in either or both of the following formats: (i) Stock Withholding: The election to have the Corporation withhold, from the shares of Common Stock otherwise issuable upon the exercise of such Non-Statutory Option or the vesting of such shares, a portion of those shares with an aggregate Fair Market Value equal to the percentage of the Withholding Taxes (not to exceed one hundred percent (100%)) designated by the holder. (ii) Stock Delivery: The election to deliver to the Corporation, at the time the Non-Statutory Option is exercised or the shares vest, one or more shares of Common Stock previously acquired by such holder (other than in connection with the option exercise or share vesting triggering the Withholding Taxes) with an aggregate Fair Market Value equal to the percentage of the Withholding Taxes (not to exceed one hundred percent (100%)) designated by the holder. II. EFFECTIVE DATE AND TERM OF THE PLAN The Plan became effective on the Plan Effective Date and shall remain in effect until the earliest of (i) August 16, 2009, (ii) the date on which all shares available for issuance under the Plan shall have been issued as fully-vested shares pursuant to option exercises under the Plan or (iii) the termination of all outstanding options in connection with a Corporate Transaction. Upon such Plan termination, all outstanding stock options and unvested stock issuances made pursuant to option exercises shall continue to have force and effect in accordance with the provisions of the documents evidencing such options or issuances. 14

III. AMENDMENT OF THE PLAN A. The Board shall have complete and exclusive power and authority to amend or modify the Plan in any or all respects, subject to any shareholder approval which may be required pursuant to applicable laws or regulations, provided, however, that the Board may not, without shareholder approval, (i) increase the number of shares of Common Stock authorized for issuance under the Plan, or (ii) materially increase the benefits offered to participants under the 1999 Plan. No amendment or modification shall adversely affect any rights and obligations with respect to options or unvested shares of Common Stock at the time outstanding under the Plan unless the Optionee or holder of such unvested shares consents to such amendment or modification. B. The Plan was amended on August 17, 2000 to increase the number of shares of Common Stock authorized for issuance under the Plan by an additional 15,000,000 shares. The amendment is subject to shareholder approval at the 2000 Annual Shareholders Meeting, and no option grant shall be made on the basis of the 15,000,000-share increase, unless and until such shareholder approval is obtained. C. Options to purchase shares of Common Stock may be granted under the Discretionary Option Grant Program in excess of the number of shares then available for issuance under the Plan, provided any excess shares actually issued under such program are held in escrow until there is obtained shareholder approval of an amendment sufficiently increasing the number of shares of Common Stock available for issuance under the Plan. If such shareholder approval is not obtained within twelve (12) months after the date the first such excess grants are made, then (i) any unexercised options granted on the basis of such excess shares shall terminate and cease to be outstanding and (ii) the Corporation shall promptly refund to the Optionees the exercise price paid for any excess shares issued under the Plan and held in escrow, together with interest (at the applicable Short Term Federal Rate) for the period the shares were held in escrow, and such shares shall thereupon be automatically cancelled and cease to be outstanding. IV. REGULATORY APPROVALS A. The implementation of the Plan, the granting of any option under the Plan and the issuance of any shares of Common Stock upon the exercise of such option shall be subject to the Corporation's procurement of all approvals and permits required by regulatory authorities having jurisdiction over the Plan, the options granted under it and the shares of Common Stock issued pursuant to it. B. No shares of Common Stock or other assets shall be issued or delivered under the Plan unless and until there shall have been compliance with all applicable requirements of Federal and state securities laws, including the filing and effectiveness of the Form S-8 registration statement for the shares of Common Stock issuable under the Plan, and all applicable listing requirements of any stock exchange (or the Nasdaq National Market, if applicable) on which Common Stock is then listed for trading. 15

V. USE OF PROCEEDS Any cash proceeds received by the Corporation from the sale of shares of Common Stock under the Plan shall be used for general corporate purposes. VI. NO EMPLOYMENT/SERVICE RIGHTS Nothing in the Plan shall confer upon the Optionee any right to continue in Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Corporation (or any Parent or Subsidiary employing or retaining such person) or of the Optionee, which rights are hereby expressly reserved by each, to terminate such person's Service at any time for any reason, with or without cause. 16
