Reference is made to page II-3 of this Registration Statement. 99.1 Network Appliance, Inc. 1999 Stock Option Plan. Item 9. Undertakings A. The undersigned Registrant hereby undertakes: (1) to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) to include any prospectus required by Section 10(a)(3) of the 1933 Act, (ii) to reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement and (iii) to include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement; provided, however, that clauses (1)(i) and (1)(ii) shall not apply if the information required to be included in a post-effective amendment by those clauses is contained in periodic reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the 1934 Act that are incorporated by reference into this Registration Statement; (2) that for the purpose of determining any liability under the 1933 Act each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and (3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the Network Appliance, Inc. 1999 Stock Option Plan. B. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the 1933 Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act that is incorporated by reference into this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. C. Insofar as indemnification for liabilities arising under the 1933 Act may be permitted to directors, officers or controlling persons of the Registrant pursuant to the indemnification provisions summarized in Item 6 or otherwise, the Registrant has been advised that, in the opinion of the Commission, such indemnification is against public policy as expressed in the 1933 Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the 1933 Act and will be governed by the final adjudication of such issue.

1 EXHIBIT 5 OPINION AND CONSENT OF BROBECK, PHLEGER & HARRISON LLP March 21, 2001 Network Appliance, Inc. 495 East Java Drive Sunnyvale, CA 94089 Re: Network Appliance, Inc. - Registration Statement for Offering of 15,000,000 Shares of Common Stock ---------------------------------------------------------------- Dear Ladies and Gentlemen: We have acted as counsel to Network Appliance, Inc., a California corporation (the "Company"), in connection with the registration on Form S-8 (the "Registration Statement") under the Securities Act of 1933, as amended, of an additional 15,000,000 shares of the Company's common stock reserved for issuance under the Company's 1999 Stock Option Plan (the "Plan"). This opinion is being furnished in accordance with the requirements of Item 8 of Form S-8 and Item 601(b)(5)(i) of Regulation S-K. We have reviewed the Company's charter documents and the corporate proceedings taken by the Company with respect to the establishment and amendment of the Plan. Based on such review, we are of the opinion that, if, as and when the shares of the Company's common stock are issued and sold (and the consideration therefor received) pursuant to the provisions of stock option agreements duly authorized under the Plan and in accordance with the Registration Statement, such shares will be duly authorized, legally issued, fully paid and nonassessable. We consent to the filing of this opinion letter as Exhibit 5 to the Registration Statement. This opinion letter is rendered as of the date first written above and we disclaim any obligation to advise you of facts, circumstances, events or developments which hereafter may be brought to our attention and which may alter, affect or modify the opinion expressed herein. Our opinion is expressly limited to the matters set forth above and we render no opinion, whether by implication or otherwise, as to any other matters relating to the Company, the Plan, or the shares of the Company's common stock issuable under such plan. Very truly yours, /s/ BROBECK, PHLEGER & HARRISON LLP BROBECK, PHLEGER & HARRISON LLP

1 Exhibit 99.1 NETWORK APPLIANCE, INC. 1999 STOCK OPTION PLAN AS AMENDED AND RESTATED THROUGH AUGUST 17, 2000 ARTICLE ONE GENERAL PROVISIONS I. 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 this 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. ADMINISTRATION OF THE PLAN A. The Primary Committee shall have sole and exclusive authority to administer the Discretionary Option Grant Program with respect to Section 16 Insiders. Administration of the Discretionary Option Grant Program with respect to all other eligible

2 persons may, at the Board's discretion, be vested in the Primary Committee or a Secondary Committee, or the Board may retain the power to administer that program with respect to all such persons. B. 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

3 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. 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

4 D. Should any change be made to the Common Stock by reason of an 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

5 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

6 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

7 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

8 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

9 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

10 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

11 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

12 (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

13 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

14 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

15 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

16 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
