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. Employee Stock Purchase Plan, the Network Appliance, Inc. 1995 Stock Incentive Plan, and the Orca Systems, Inc. 1999 Stock Option/Stock Issuance Plan (as assumed by Registrant). 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 99.1 NETWORK APPLIANCE, INC. EMPLOYEE STOCK PURCHASE PLAN (AMENDED AND RESTATED THROUGH AUGUST 17, 1999)

2 NETWORK APPLIANCE, INC EMPLOYEE STOCK PURCHASE PLAN AS AMENDED AND RESTATED EFFECTIVE AUGUST 17, 1999 I. PURPOSE OF THE PLAN This Employee Stock Purchase Plan is intended to promote the interests of Network Appliance, Inc. by providing eligible employees with the opportunity to acquire a proprietary interest in the Corporation through participation in a payroll-deduction based employee stock purchase plan designed to qualify under Section 423 of the Code. Capitalized terms herein shall have the meanings assigned to such terms in the attached Appendix. All share numbers which appear in this August 17, 1999 restatement of the Plan reflect (i) the two-for-one split of the Common Stock effected on December 19, 1997, (ii) the two-for-one split of the Common Stock effected on December 22, 1998, (iii) the two-for-one split of the Common Stock effected on December 21, 1999, and (iv) the two-for-one split of the Common Stock effected on March 23, 2000. II. ADMINISTRATION OF THE PLAN The Plan Administrator shall have full authority to interpret and construe any provision of the Plan and to adopt such rules and regulations for administering the Plan as it may deem necessary in order to comply with the requirements of Code Section 423. Decisions of the Plan Administrator shall be final and binding on all parties having an interest in the Plan. III. STOCK SUBJECT TO PLAN A. The stock purchasable under the Plan shall be shares of authorized but unissued or reacquired Common Stock, including shares of Common Stock purchased 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 Eight Million Two Hundred Thousand (8,200,000) shares, including (i) an increase of One Million Six Hundred Thousand (1,600,000) shares authorized by the Board on August 11, 1998, and approved by the shareholders on October 8, 1998, and (ii) an increase of One Million (1,000,000) shares authorized by the Board on August 17, 1999, and approved by the shareholders on October 26, 1999. B. 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 class of securities issuable under the Plan, (ii) the maximum number and class of securities purchasable per Participant on any one Purchase Date, (iii) the maximum number and class of securities purchasable in the aggregate by all Participants on any one purchase date under the Plan and (iv)

3 the number and class of securities and the price per share in effect under each outstanding purchase right in order to prevent the dilution or enlargement of benefits thereunder. IV. OFFERING PERIODS A. Shares of Common Stock shall be offered for purchase under the Plan through a series of successive offering periods until such time as (i) the maximum number of shares of Common Stock available for issuance under the Plan shall have been purchased or (ii) the Plan shall have been sooner terminated. B. Each offering period shall be of such duration (not to exceed twenty-four (24) months) as determined by the Plan Administrator prior to the start date. However, the initial offering period shall commence at the Effective Time and terminate on the last business day in November 1997. The next offering period shall commence on the first business day in December 1997, and subsequent offering periods shall commence as designated by the Plan Administrator. C. Each offering period shall be comprised of a series of one or more successive Purchase Intervals. Purchase Intervals shall run from the first business day in June each year to the last business day in November of the same year and from the first business day in December each year to the last business day in May of the following year. However, the first Purchase Interval in effect under the initial offering period commenced at the Effective Time and terminated on the last business day in May 1996. V. ELIGIBILITY A. An individual who is an Eligible Employee may enter an offering period under the Plan on the start date of any Purchase Interval within that offering period, provided he or she remains an Eligible Employee on that date. The date an individual enters an offering period shall be designated his or her Entry Date for purposes of that offering period. B. To participate in the Plan for a particular offering period, the Eligible Employee must complete the enrollment forms prescribed by the Plan Administrator (including a stock purchase agreement and a payroll deduction authorization form) and file such forms with the Plan Administrator (or its designate) on or before his or her scheduled Entry Date. VI. PAYROLL DEDUCTIONS A. For offering periods which commenced before December 1, 1999, the payroll deduction authorized by the Participant for purposes of acquiring shares of Common Stock during such offering period may be any multiple of one percent (1%) of the Base Salary paid to the Participant during each Purchase Interval within that offering period, up to a maximum of ten percent (10%). For the offering period scheduled to commence on December 1, 1999, each Participant's payroll deduction shall be based on such Participant's Cash Earnings and may be any multiple of one percent (1%) of Cash Earnings paid to the Participant during each Purchase Interval within that offering period, up to a maximum of ten percent (10%). 2

4 The deduction rate so authorized by a Participant shall continue in effect throughout the offering period, except to the extent such rate is changed in accordance with the following guidelines: (i) The Participant may, at any time during the offering period, reduce his or her rate of payroll deduction to become effective as soon as possible after filing the appropriate form with the Plan Administrator. The Participant may not, however, effect more than one (1) such reduction per Purchase Interval. (ii) The Participant may, prior to the commencement of any new Purchase Interval within the offering period, increase the rate of his or her payroll deduction by filing the appropriate form with the Plan Administrator. The new rate (which may not exceed the ten percent (10%) maximum) shall become effective as of the start date of the first Purchase Interval following the filing of such form. B. Payroll deductions shall begin on the first pay day following the Participant's Entry Date into the offering period and shall (unless sooner terminated by the Participant) continue through the pay day ending with or immediately prior to the last day of that offering period. The amounts so collected shall be credited to the Participant's book account under the Plan, but no interest shall be paid on the balance from time to time outstanding in such account. The amounts collected from the Participant shall not be held in any segregated account or trust fund and may be commingled with the general assets of the Corporation and used for general corporate purposes. C. Payroll deductions shall automatically cease upon the termination of the Participant's purchase right in accordance with the provisions of the Plan. D. The Participant's acquisition of Common Stock under the Plan on any Purchase Date shall neither limit nor require the Participant's acquisition of Common Stock on any subsequent Purchase Date, whether within the same or a different offering period. E. The Plan Administrator shall have the discretion, exercisable prior to the start date of any offering period under the Plan, to determine whether the payroll deductions authorized by Participants during such offering period shall be calculated as a percentage of Base Salary or Cash Earnings. VII. PURCHASE RIGHTS A. GRANT OF PURCHASE RIGHT. A Participant shall be granted a separate purchase right for each offering period in which he or she participates. The purchase right shall be granted on the Participant's Entry Date into the offering period and shall provide the Participant with the right to purchase shares of Common Stock, in a series of successive installments over the remainder of such offering period, upon the terms set forth below. The Participant shall execute a stock purchase agreement embodying such terms and such other provisions (not inconsistent with the Plan) as the Plan Administrator may deem advisable. 3

5 Under no circumstances shall purchase rights be granted under the Plan to any Eligible Employee if such individual would, immediately after the grant, own (within the meaning of Code Section 424(d)) or hold outstanding options or other rights to purchase, stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Corporation or any Corporate Affiliate. B. EXERCISE OF THE PURCHASE RIGHT. Each purchase right shall be automatically exercised in installments on each successive Purchase Date within the offering period, and shares of Common Stock shall accordingly be purchased on behalf of each Participant (other than Participants whose payroll deductions have previously been refunded pursuant to the Termination of Purchase Right provisions below) on each such Purchase Date. The purchase shall be effected by applying the Participant's payroll deductions for the Purchase Interval ending on such Purchase Date to the purchase of whole shares of Common Stock at the purchase price in effect for the Participant for that Purchase Date. C. PURCHASE PRICE. The purchase price per share at which Common Stock will be purchased on the Participant's behalf on each Purchase Date within the offering period shall be equal to eighty-five percent (85%) of the lower of (i) the Fair Market Value per share of Common Stock on the Participant's Entry Date into that offering period or (ii) the Fair Market Value per share of Common Stock on that Purchase Date. However, for each Participant whose Entry Date is other than the start date of the offering period, the clause (i) amount shall in no event be less than the Fair Market Value per share of Common Stock on the start date of that offering period. D. NUMBER OF PURCHASABLE SHARES. The number of shares of Common Stock purchasable by a Participant on each Purchase Date during the offering period shall be the number of whole shares obtained by dividing the amount collected from the Participant through payroll deductions during the Purchase Interval ending with that Purchase Date by the purchase price in effect for the Participant for that Purchase Date. However, the maximum number of shares of Common Stock purchasable per Participant on any one Purchase Date shall not exceed Twelve Thousand (12,000) shares, subject to periodic adjustments in the event of certain changes in the Corporation's capitalization. The maximum number of shares of Common Stock purchasable in the aggregate by all participants on any one Purchase Date shall not exceed One Million Six Hundred Thousand (1,600,000) shares, subject to periodic adjustments in the event of certain changes in the Corporation's capitalization. However, the Plan Administrator shall have the discretionary authority, exercisable prior to the start of any offering period under the Plan, to increase or decrease the limitations to be in effect for the number of shares purchasable per Participant and in total by all Participants on each Purchase Date during that offering period. E. EXCESS PAYROLL DEDUCTIONS. Any payroll deductions not applied to the purchase of shares of Common Stock on any Purchase Date because they are not sufficient to purchase a whole share of Common Stock shall be held for the purchase of Common Stock on the next Purchase Date. However, any payroll deductions not applied to the purchase of Common Stock by reason of the limitation on the maximum number of shares purchasable by the Participant on the Purchase Date shall be promptly refunded. 4

6 F. TERMINATION OF PURCHASE RIGHT. The following provisions shall govern the termination of outstanding purchase rights: (i) A Participant may, at any time prior to the next scheduled Purchase Date in the offering period, terminate his or her outstanding purchase right by filing the appropriate form with the Plan Administrator (or its designate), and no further payroll deductions shall be collected from the Participant with respect to the terminated purchase right. Any payroll deductions collected during the Purchase Interval in which such termination occurs shall, at the Participant's election, be immediately refunded or held for the purchase of shares on the next Purchase Date. If no such election is made at the time such purchase right is terminated, then the payroll deductions collected with respect to the terminated right shall be refunded as soon as possible. (ii) The termination of such purchase right shall be irrevocable, and the Participant may not subsequently rejoin the offering period for which the terminated purchase right was granted. In order to resume participation in any subsequent offering period, such individual must re-enroll in the Plan (by making a timely filing of the prescribed enrollment forms) on or before his or her scheduled Entry Date into that offering period. (iii) Should the Participant cease to remain an Eligible Employee for any reason (including death, disability or change in status) while his or her purchase right remains outstanding, then that purchase right shall immediately terminate, and all of the Participant's payroll deductions for the Purchase Interval in which the purchase right so terminates shall be immediately refunded. However, should the Participant cease to remain in active service by reason of an approved unpaid leave of absence, then the Participant shall have the right, exercisable up until the last business day of the Purchase Interval in which such leave commences, to (a) withdraw all the payroll deductions collected to date on his or her behalf for that Purchase Interval or (b) have such funds held for the purchase of shares on his or her behalf on the next scheduled Purchase Date. In no event, however, shall any further payroll deductions be collected on the Participant's behalf during such leave. Upon the Participant's return to active service (i) within ninety (90) days following the commencement of such leave or (ii) prior to the expiration of any longer period for which such Participant's right to reemployment with the Corporation is guaranteed by either statute or contract, his or her payroll deductions under the Plan shall automatically resume at the rate in effect at the time the leave began, unless the Participant withdraws from the Plan prior to his or her return. An individual who returns to active employment following a leave of absence which exceeds in duration the applicable time period shall be treated as a new Employee for purposes of subsequent participation in the Plan and must accordingly re-enroll in the Plan (by making a timely filing of the prescribed enrollment forms) on or before his or her scheduled Entry Date into the offering period. 5

7 G. CHANGE IN CONTROL. Each outstanding purchase right shall automatically be exercised, immediately prior to the effective date of any Change in Control, by applying the payroll deductions of each Participant for the Purchase Interval in which such Change in Control occurs to the purchase of whole shares of Common Stock at a purchase price per share equal to eighty-five percent (85%) (or such greater percentage as the Plan Administrator may have established for the offering period in which the Change in Control occurs) of the lower of (i) the Fair Market Value per share of Common Stock on the Participant's Entry Date into the offering period in which such Change in Control occurs or (ii) the Fair Market Value per share of Common Stock immediately prior to the effective date of such Change in Control. However, the applicable limitation on the number of shares of Common Stock purchasable per Participant shall continue to apply to any such purchase, and the clause (i) amount above shall not, for any Participant whose Entry Date for the offering period is other than the start date of that offering period, be less than the Fair Market Value per share of Common Stock on that start date. The Corporation shall use its best efforts to provide at least ten (10) days prior written notice of the occurrence of any Change in Control, and Participants shall, following the receipt of such notice, have the right to terminate their outstanding purchase rights prior to the effective date of the Change in Control. H. PRORATION OF PURCHASE RIGHTS. Should the total number of shares of Common Stock to be purchased pursuant to outstanding purchase rights on any particular date exceed either (i) the maximum limitation on the number of shares purchasable in the aggregate on such date or (ii) the number of shares then available for issuance under the Plan, the Plan Administrator shall make a pro-rata allocation of the available shares on a uniform and nondiscriminatory basis, and the payroll deductions of each Participant, to the extent in excess of the aggregate purchase price payable for the Common Stock pro-rated to such individual, shall be refunded. I. ASSIGNABILITY. The purchase right shall be exercisable only by the Participant and shall not be assignable or transferable by the Participant. J. SHAREHOLDER RIGHTS. A Participant shall have no shareholder rights with respect to the shares subject to his or her outstanding purchase right until the shares are purchased on the Participant's behalf in accordance with the provisions of the Plan and the Participant has become a holder of record of the purchased shares. VIII. ACCRUAL LIMITATIONS A. No Participant shall be entitled to accrue rights to acquire Common Stock pursuant to any purchase right outstanding under this Plan if and to the extent such accrual, when aggregated with (i) rights to purchase Common Stock accrued under any other purchase right granted under this Plan and (ii) similar rights accrued under other employee stock purchase plans (within the meaning of Code Section 423) of the Corporation or any Corporate Affiliate, would otherwise permit such Participant to purchase more than Twenty-Five Thousand Dollars ($25,000) worth of stock of the Corporation or any Corporate Affiliate (determined on the basis of the Fair Market Value per share on the date or dates such rights are granted) for each calendar year such rights are at any time outstanding. 6

8 B. For purposes of applying such accrual limitations to the purchase rights granted under the Plan, the following provisions shall be in effect: (i) The right to acquire Common Stock under each outstanding purchase right shall accrue in a series of installments on each successive Purchase Date during the offering period on which such right remains outstanding. (ii) No right to acquire Common Stock under any outstanding purchase right shall accrue to the extent the Participant has already accrued in the same calendar year the right to acquire Common Stock under one (1) or more other purchase rights at a rate equal to Twenty-Five Thousand Dollars ($25,000) worth of Common Stock (determined on the basis of the Fair Market Value per share on the date or dates of grant) for each calendar year such rights were at any time outstanding. C. If by reason of such accrual limitations, any purchase right of a Participant does not accrue for a particular Purchase Interval, then the payroll deductions which the Participant made during that Purchase Interval with respect to such purchase right shall be promptly refunded. D. In the event there is any conflict between the provisions of this Article and one or more provisions of the Plan or any instrument issued thereunder, the provisions of this Article shall be controlling. IX. EFFECTIVE DATE AND TERM OF THE PLAN A. The Plan was adopted by the Board on September 26, 1995, was subsequently approved by the shareholders and became effective at the Effective Time. The Plan was amended by the Board on August 11, 1998 (the "1998 Amendment") to increase the maximum number of shares of Common Stock authorized for issuance under the Plan by an additional One Million Six Hundred Thousand (1,600,000) shares. The 1998 Amendment was approved by the shareholders at the 1998 Annual Meeting. On August 17, 1999, the Board amended the Plan to (i) increase the maximum number of shares of Common Stock authorized for issuance under the Plan by an additional One Million (1,000,000) shares and (ii) make amendments to certain administrative provisions of the Plan (the "1999 Amendment"). The 1999 Amendment was approved by the shareholders on October 26, 1999. No purchase rights shall be granted, and no shares shall be issued, on the basis of any subsequent share increases unless approved by the shareholders. Upon such shareholder approval, the Corporation shall comply with all applicable requirements of the 1933 Act (including the registration of such additional shares of Common Stock issuable under the Plan on a Form S-8 registration statement filed with the Securities and Exchange Commission), all applicable listing requirements of the Nasdaq National Market with respect to those shares, and all other applicable requirements established by law or regulation. B. Unless sooner terminated by the Board, the Plan shall terminate upon the earliest of (i) the last business day in November 2005, (ii) the date on which all shares available for issuance under the Plan shall have been sold pursuant to purchase rights exercised under the 7

9 Plan or (iii) the date on which all purchase rights are exercised in connection with a Change in Control. No further purchase rights shall be granted or exercised, and no further payroll deductions shall be collected, under the Plan following such termination. X. AMENDMENT OF THE PLAN A. The Board may alter, amend, suspend or discontinue the Plan at any time to become effective immediately following the close of any Purchase Interval. However, the Plan may be amended or terminated immediately upon Board action, if and to the extent necessary to assure that the Corporation will not recognize, for financial reporting purposes, any compensation expense in connection with the shares of Common Stock offered for purchase under the Plan, should the financial accounting rules applicable to the Plan at the Effective Time be subsequently revised so as to require the recognition of compensation expense in the absence of such amendment or termination. B. In no event may the Board effect any of the following amendments or revisions to the Plan without the approval of the Corporation's shareholders: (i) materially increase the number of shares of Common Stock issuable under the Plan, except for permissible adjustments in the event of certain changes in the Corporation's capitalization, (ii) alter the purchase price formula so as to reduce the purchase price payable for the shares of Common Stock purchasable under the Plan or (iii) modify the requirements for eligibility to participate in the Plan. XI. GENERAL PROVISIONS A. All costs and expenses incurred in the administration of the Plan shall be paid by the Corporation. B. Nothing in the Plan shall confer upon the Participant any right to continue in the employ of the Corporation or any Corporate Affiliate for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Corporation (or any Corporate Affiliate employing such person) or of the Participant, which rights are hereby expressly reserved by each, to terminate such person's employment at any time for any reason, with or without cause. C. The provisions of the Plan shall be governed by the laws of the State of California without resort to that State's conflict-of-laws rules. 8

2 NETWORK APPLIANCE, INC. 1995 STOCK INCENTIVE PLAN (AMENDED AND RESTATED AS OF OCTOBER 26, 1999) ARTICLE ONE GENERAL PROVISIONS I. PURPOSE OF THE PLAN This 1995 Stock Incentive 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 which appear in this August 11, 1998 restatement of the Plan reflect (i) the two-for-one split of the Common Stock effected on December 19, 1997, (ii) the two-for-one split of the Common Stock effected on December 22, 1998, (iii) the two-for-one split of the Common Stock effected on December 21, 1999, and (iv) the two-for-one split of the Common Stock effected on March 23, 2000. II. STRUCTURE OF THE PLAN A. The Plan shall be divided into four 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, (ii) the Salary Investment Option Grant Program under which the Corporation's officers and other highly-compensated employees may elect to have a portion of their base salary reduced each year in return for options to purchase shares of Common Stock, (iii) the Stock Issuance Program under which eligible persons may, at the discretion of the Plan Administrator, be issued shares of Common Stock directly, either through the immediate purchase of such shares or as a bonus for services rendered the Corporation (or any Parent or Subsidiary), and

3 (iv) the Automatic Option Grant Program under which Eligible Directors shall automatically receive option grants at periodic intervals to purchase shares of Common Stock. B. The provisions of Articles One and Six 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 and Stock Issuance Programs with respect to Section 16 Insiders. Administration of the Discretionary Option Grant and Stock Issuance Programs with respect to all other persons eligible to participate in those programs 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 those programs with respect to all such persons. The Primary Committee shall also have the sole and exclusive authority to administer the Salary Investment Option Grant Program and to select the eligible individuals who are to participate in that program for one or more calendar years. 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 and Stock Issuance Programs and to make such determinations under, and issue such interpretations of, the provisions of such programs and any outstanding options or stock issuances 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 or Stock Issuance Program under its jurisdiction or any stock option or stock issuance 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 or stock issuances 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. 2

4 IV. ELIGIBILITY A. The persons eligible to participate in the Discretionary Option Grant and Stock Issuance Programs are as follows: (i) Employees, (ii) non-employee members of the Board or the board of directors of any Parent or Subsidiary, and (iii) consultants and other independent advisors who provide services to the Corporation (or any Parent or Subsidiary). B. Only the Corporation's officers and other highly-compensated Employees shall be eligible to participate in the Salary Investment Option Grant Program. C. 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, (i) with respect to the option grants under the Discretionary Option Grant Program, which eligible persons are to receive option grants, 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 and (ii) with respect to stock issuances under the Stock Issuance Program, which eligible persons are to receive stock issuances, the time or times when such issuances are to be made, the number of shares to be issued to each Participant, the vesting schedule (if any) applicable to the issued shares and the consideration to be paid for such shares. The Primary Committee shall have sole and exclusive authority to select the individuals eligible to participate in the Salary Investment Option Grant Program, but all options granted under such program shall be made solely in accordance with the express terms and conditions of Article Three of the Plan. D. The Plan Administrator shall have the absolute discretion either to grant options in accordance with the Discretionary Option Grant Program or to effect stock issuances in accordance with the Stock Issuance Program. E. The individuals eligible to participate in the Automatic Option Grant Program shall be limited to (i) those individuals who first become non-employee Board members on or after the Plan Effective Date, whether through appointment by the Board or election by the Corporation's stockholders, and (ii) those individuals who are re-elected as non-employee Board members at one or more Annual Stockholders Meetings held after the Plan Effective Date, including those individuals serving as non-employee Board members on the Plan Effective Date. A non-employee Board member who has previously been in the employ of the Corporation (or any Parent or Subsidiary) shall not be eligible to receive an initial option grant under the 3

5 Automatic Option Grant Program on the Plan Effective Date or (if later) at the time he or she first becomes a non-employee Board member, but such individual shall be eligible to receive periodic option grants under the Automatic Option Grant Program upon his or her re-election as a non-employee Board member at one or more Annual Stockholders Meetings. 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 101,700,192 shares. Such authorized share reserve includes (i) the increase of an additional 25,600,000 shares authorized by the Board on July 17, 1997 and approved by the stockholders at the 1997 Annual Meeting on September 25, 1997 and (ii) an additional increase of 21,600,000 shares authorized by the Board on August 11, 1998 and approved by the stockholders on at the 1998 Annual Meeting on October 8, 1998. B. No one person participating in the Plan may receive options and direct stock issuances for more than 8,000,000 shares of Common Stock in the aggregate per calendar year, beginning with the 1995 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 (including any options incorporated from the Predecessor Plan) 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 or direct issue 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 or direct stock issuances under the Plan. Should the exercise price of an option under the Plan (including any option incorporated from the Predecessor 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 a stock issuance 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 which vest under the stock issuance, and not by the net number of shares of Common Stock issued to the holder of such option or stock issuance. 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 options and direct stock issuances per calendar year, (iii) the number and/or class of securities for which automatic option grants are to be made subsequently per Eligible Director under the Automatic Option Grant Program and (iv) the number and/or 4

6 class of securities and the exercise price per share in effect under each outstanding option (including any option incorporated from the Predecessor Plan) in order to prevent the dilution or enlargement of benefits thereunder. The adjustments determined by the Plan Administrator shall be final, binding and conclusive. 5

7 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. 6

8 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. 7

9 D. Stockholder Rights. The holder of an option shall have no stockholder 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. 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 descent and distribution following the Optionee's death. Non-Statutory Options shall be subject to the same limitation, except that a Non-Statutory Option may, in connection with the Optionee's estate plan, be assigned in whole or in part 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. 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 Six 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. Exercise Price. The exercise price per share shall not be less than one hundred percent (100%) of the Fair Market Value per share of Common Stock on the option grant date. C. 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. 8

10 D. 10% Stockholder. If any Employee to whom an Incentive Option is granted is a 10% Stockholder, 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. III. CORPORATE TRANSACTION/CHANGE IN CONTROL A. In the event of any Corporate Transaction, each outstanding option shall automatically accelerate so that each such option shall, immediately prior to the effective date of the Corporate Transaction, become fully exercisable with respect to the total number of 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 so accelerate if and to the extent: (i) such option is, in connection with the Corporate Transaction, either to be assumed by the successor corporation (or parent thereof) or to be 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 such option 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 and direct stock issuances under the Plan per calendar year. 9

11 E. The Plan Administrator shall have full power and authority to grant options under the Discretionary Option Grant Program 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 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. F. The Plan Administrator shall have full power and authority to grant options under the Discretionary Option Grant Program 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. 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 Discretionary Option Grant Program (including outstanding options incorporated from the Predecessor 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. 10

12 ARTICLE THREE SALARY INVESTMENT OPTION GRANT PROGRAM I. OPTION GRANTS The Primary Committee shall have the sole and exclusive authority to determine the calendar year or years (if any) for which the Salary Investment Option Grant Program is to be in effect and to select the Corporation's officers and other highly compensated Employees who are to participate in the Salary Investment Option Grant Program for those calendar year or years. Each selected individual who elects to participate in the Salary Investment Option Grant Program must, prior to the start of each calendar year of participation, file with the Primary Committee (or its designate) an irrevocable authorization directing the Corporation to reduce his or her salary for that calendar year. The minimum amount of authorized salary reduction shall not be less than Fifteen Thousand Dollars ($15,000), and the maximum salary reduction amount authorized by any individual shall not exceed Seventy Five Thousand Dollars ($75,000). Each selected individual who files a proper salary reduction authorization shall automatically be granted an option under this Salary Investment Option Grant Program on the first trading day in January of the calendar year for which that salary reduction is to be in effect. II. OPTION TERMS Each option shall be a Non-Statutory Option evidenced by one or more documents in the form approved by the Primary Committee; provided, however, that each such document shall comply with the terms specified below. A. Exercise Price. 1. The exercise price per share shall be thirty-three and one-third percent (33-1/3%) 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 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. B. Number of Option Shares. The number of shares of Common Stock subject to the option shall be determined pursuant to the following formula (rounded down to the nearest whole number): X = A divided by (B x 66-2/3%), where X is the number of option shares, 11

13 A is the dollar amount by which the Optionee's base salary is to be reduced for the calendar year, and B is the Fair Market Value per share of Common Stock on the option grant date. C. Exercise and Term of Options. The option shall become exercisable in a series of twelve (12) successive equal monthly installments upon the Optionee's completion of each calendar month of Service in the calendar year for which the salary reduction is in effect. Each option shall have a maximum term of ten (10) years measured from the option grant date. D. Effect of Termination of Service. Should the Optionee cease Service for any reason while holding one or more options under this Article Three, then each such option shall remain exercisable, for any or all of the shares for which the option is exercisable at the time of such cessation of Service, until the expiration of the ten (10)-year option term. Should the Optionee die while holding one or more options under this Article Three, then each such option may be exercised, for any or all of the shares for which the option is exercisable at the time of the Optionee's cessation of Service (less any shares subsequently purchased by Optionee prior to death), 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. Such right of exercise shall lapse, and the option shall terminate, upon the expiration of the ten (10)-year option term. However, the option shall, immediately upon the Optionee's cessation of Service for any reason, terminate and cease to remain outstanding with respect to any and all shares of Common Stock for which the option is not otherwise at that time exercisable. III. CORPORATE TRANSACTION/CHANGE IN CONTROL A. Should any Corporate Transaction be effected while the Optionee remains in Service, then each outstanding option held by such Optionee under the Salary Investment Option Grant Program shall automatically accelerate so that each such option shall, immediately prior to the effective date of the Corporate Transaction, become fully exercisable with respect to the total number of 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. Each such outstanding option shall be assumed by the successor corporation (or parent thereof) in the Corporate Transaction and shall remain exercisable for the fully-vested shares until the expiration of the ten (10)-year option term. B. Should any Change in Control occur while the Optionee remains in Service, then each outstanding option held by such Optionee under the Salary Investment Option Grant Program shall automatically accelerate so that each such option shall, immediately prior to the effective date of the Change in Control, become fully exercisable with respect to the total number of 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. The option shall remain so exercisable until the expiration of the ten (10)-year option term. 12

14 C. The grant of options under the Salary Investment 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. IV. REMAINING TERMS The remaining terms of each option granted under the Salary Investment Option Grant Program shall be the same as the terms in effect for option grants made under the Discretionary Option Grant Program. 13

15 ARTICLE FOUR STOCK ISSUANCE PROGRAM I. STOCK ISSUANCE TERMS Shares of Common Stock may be issued under the Stock Issuance Program through direct and immediate issuances without any intervening option grants. Each such stock issuance shall be evidenced by a Stock Issuance Agreement which complies with the terms specified below. Shares of Common Stock may also be issued under the Stock Issuance Program pursuant to share right awards which entitle the recipients to receive those shares upon the attainment of designated performance goals. A. Purchase Price. 1. The purchase price per share of Common Stock subject to direct issuance 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 issuance date. 2. Shares of Common Stock may be issued under the Stock Issuance Program for any of the following items of consideration which the Plan Administrator may deem appropriate in each individual instance: (i) cash or check made payable to the Corporation, or (ii) past services rendered to the Corporation (or any Parent or Subsidiary). B. Vesting/Issuance Provisions. 1. The Plan Administrator may issue shares of Common Stock under the Stock Issuance Program which are fully and immediately vested upon issuance or which are to vest in one or more installments over the Participant's period of Service or upon attainment of specified performance objectives. The elements of the vesting schedule applicable to any unvested shares of Common Stock issued under the Stock Issuance Program, namely: (i) the Service period to be completed by the Participant or the performance objectives to be attained, (ii) the number of installments in which the shares are to vest, (iii) the interval or intervals (if any) which are to lapse between installments, and 14

16 (iv) the effect which death, Permanent Disability or other event designated by the Plan Administrator is to have upon the vesting schedule, shall be determined by the Plan Administrator and incorporated into the Stock Issuance Agreement. Alternatively, the Plan Administrator may issue share right awards under the Stock Issuance Program which shall entitle the recipient to receive a specified number of shares of Common Stock upon the attainment of one or more performance goals established by the Plan Administrator. Upon the attainment of such performance goals, fully-vested shares of Common Stock shall be issued in satisfaction of those share right awards. 2. Any new, substituted or additional securities or other property (including money paid other than as a regular cash dividend) which the Participant may have the right to receive with respect to his or her unvested shares of Common Stock by reason of any stock dividend, stock split, 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 shall be issued subject to (i) the same vesting requirements applicable to the Participant's unvested shares of Common Stock and (ii) such escrow arrangements as the Plan Administrator shall deem appropriate. 3. The Participant shall have full stockholder rights with respect to any shares of Common Stock issued to the Participant under the Stock Issuance Program, whether or not the Participant's interest in those shares is vested. Accordingly, the Participant shall have the right to vote such shares and to receive any regular cash dividends paid on such shares. 4. Should the Participant cease to remain in Service while holding one or more unvested shares of Common Stock issued under the Stock Issuance Program or should the performance objectives not be attained with respect to one or more such unvested shares of Common Stock, then those shares shall be immediately surrendered to the Corporation for cancellation, and the Participant shall have no further stockholder rights with respect to those shares. To the extent the surrendered shares were previously issued to the Participant for cash consideration, the Corporation shall repay that consideration to the Participant at the time the shares are surrendered. 5. The Plan Administrator may in its discretion waive the surrender and cancellation of one or more unvested shares of Common Stock (or other assets attributable thereto) which would otherwise occur upon the cessation of the Participant's Service or the non-attainment of the performance objectives applicable to those shares. Such waiver shall result in the immediate vesting of the Participant's interest in the shares of Common Stock as to which the waiver applies. Such waiver may be effected at any time, whether before or after the Participant's cessation of Service or the attainment or non-attainment of the applicable performance objectives. 15

17 6. Outstanding share right awards under the Stock Issuance Program shall automatically terminate, and no shares of Common Stock shall actually be issued in satisfaction of those awards, if the performance goals established for such awards are not attained. The Plan Administrator, however, shall have the discretionary authority to issue shares of Common Stock in satisfaction of one or more outstanding share right awards as to which the designated performance goals are not attained. II. CORPORATE TRANSACTION/CHANGE IN CONTROL A. All of the Corporation's outstanding repurchase rights under the Stock Issuance Program shall terminate automatically, and all 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 in the Stock Issuance Agreement. B. The Plan Administrator shall have the discretionary authority, exercisable either at the time the unvested shares are issued or any time while the Corporation's repurchase rights remain outstanding under the Stock Issuance Program, to provide that those rights shall automatically terminate in whole or in part, and the shares of Common Stock subject to those terminated rights shall immediately vest, in the event the Participant's Service should subsequently terminate by reason of an Involuntary Termination within twelve (12) months following the effective date of any Corporate Transaction in which those repurchase rights are assigned to the successor corporation (or parent thereof). C. The Plan Administrator shall have the discretionary authority, exercisable either at the time the unvested shares are issued or any time while the Corporation's repurchase rights remain outstanding under the Stock Issuance Program, to provide that those rights shall automatically terminate in whole or in part, and the shares of Common Stock subject to those terminated rights shall immediately vest, in the event the Participant's Service should subsequently terminate by reason of an Involuntary Termination within twelve (12) months following the effective date of any Change in Control. III. SHARE ESCROW/LEGENDS Unvested shares may, in the Plan Administrator's discretion, be held in escrow by the Corporation until the Participant's interest in such shares vests or may be issued directly to the Participant with restrictive legends on the certificates evidencing those unvested shares. 16

18 ARTICLE FIVE AUTOMATIC OPTION GRANT PROGRAM The Automatic Option Grant Program under the Plan was replaced by a new automatic option grant program for non-employee Board members under the Corporation's 1999 Stock Option Plan, effective October 26, 1999. Accordingly, no further option grants are to be made under this Automatic Option Grant Program after October 25, 1999. However, any outstanding option grants made under this Automatic Option Grant Program prior to October 26, 1999 shall continue in full force and effect in accordance with the terms and provisions of this Article Five and the applicable stock option agreement for each such grant. All automatic option grants made to non-employee Board members on or after October 26, 1999, whether upon their initial election or appointment to the Board or upon their re-election at one or more subsequent Annual Shareholder Meetings shall be effected solely and exclusively in accordance with the terms and provisions of the Automatic Option Grant Program in effect under the 1999 Stock Option Plan. I. OPTION TERMS A. GRANT DATES. No additional option grants shall be made under this Automatic Option Grant Program after October 25, 1999. The terms and provisions of this Article Five shall apply to all option grants made under the Automatic Option Grant Program prior to such date. 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. The shares subject to each initial automatic option grant made to a newly-elected or appointed non-employee Board member shall vest, and the Corporation's repurchase right with respect to those shares 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 17

19 completion of one (1) year of Board service measured from the option grant date. The shares subject to each annual automatic option grant made to a continuing non-employee Board member 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 Stockholders 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 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. (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). 18

20 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. 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. 19

21 ARTICLE SIX 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 may 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 A. The Plan became effective on the Plan Effective Date and serves as the successor to the Predecessor Plan, and no further option grants or direct stock issuances are to be made under the Predecessor Plan after the Plan Effective Date. All options outstanding under the Predecessor Plan as of such date have been incorporated into the Plan and shall be treated as outstanding options under the Plan. However, each outstanding option so incorporated shall continue to be governed solely by the terms of the documents evidencing such option, and no provision of the Plan shall be deemed to affect or otherwise modify the rights or obligations of the holders of such incorporated options with respect to their acquisition of shares of Common Stock. 20

22 B. One or more provisions of the Plan, including (without limitation) the option/vesting acceleration provisions of Article Two relating to Corporate Transactions and Changes in Control, may, in the Plan Administrator's discretion, be extended to one or more options incorporated from the Predecessor Plan which do not otherwise contain such provisions. C. The Plan shall terminate upon the earliest of (i) August 31, 2005, (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 or direct stock issuances 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 shall continue to have force and effect in accordance with the provisions of the documents evidencing such options or issuances. 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. However, no such amendment or modification shall adversely affect any rights and obligations with respect to options or unvested stock issuances at the time outstanding under the Plan unless the Optionee or the Participant consents to such amendment or modification. In addition, certain amendments may require stockholder approval pursuant to applicable laws or regulations. Subject to the foregoing limitations, the Plan Administrator may make option grants and direct stock issuances under the Plan at any time before the date fixed herein for the termination of the Plan. B. The Plan was amended and restated by the Board on July 17, 1997 (the "1997 Restatement") to effect the following changes: (i) increase the maximum number of shares of Common Stock authorized for issuance over the term of the Plan from 54,500,192 shares to 80,100,192 shares, (ii) modify the vesting provisions to be in effect for future option grants made to non-employee Board members under the Automatic Option Grant Program, (iii) render the non-employee Board members who are serving as Plan Administrator eligible to receive option grants and direct stock issuances under the Discretionary Option Grant and Stock Issuance Programs, (iv) allow unvested shares issued under the Plan and subsequently repurchased by the Corporation at the option exercise price or direct issue price paid per share to be reissued under the Plan, (v) remove certain restrictions on the eligibility of non-employee Board members to serve as Plan Administrator, (vi) eliminate the stock appreciation right provisions and loan features of the Plan and (vii) effect a series of additional changes to the provisions of the Plan (including the stockholder approval requirements and the transferability of Non-Statutory Options) in order to take advantage of recent amendments to Rule 16b-3 of the Securities and Exchange Commission which exempts certain officer and director transactions under the Plan from the short-swing liability provisions of the federal securities laws. The 1997 Restatement was approved by the stockholders at the 1997 Annual Meeting held on September 25, 1997. 21

23 C. The Plan was further amended and restated by the Board on August 11, 1998 (the "1998 Restatement") to increase the maximum number of shares of Common Stock authorized for issuance over the term of the Plan from 80,100,192 shares to 101,700,192 shares. The 1998 Restatement was approved by the stockholders at the 1998 Annual Meeting held on October 8, 1998. E. Options to purchase shares of Common Stock may be granted under the Discretionary Option Grant and Salary Investment Option Grant Programs and shares of Common Stock may be issued under the Stock Issuance Program that are in each instance in excess of the number of shares then available for issuance under the Plan, provided any excess shares actually issued under those programs are held in escrow until there is obtained stockholder approval of an amendment sufficiently increasing the number of shares of Common Stock available for issuance under the Plan. If such stockholder approval is not obtained within twelve (12) months after the date the first such excess grants or issuances 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 and the Participants the exercise or purchase 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 either upon the exercise of any option or under the Stock Issuance Program 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. 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. 22

24 VI. NO EMPLOYMENT/SERVICE RIGHTS Nothing in the Plan shall confer upon the Optionee or the Participant 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 or the Participant, which rights are hereby expressly reserved by each, to terminate such person's Service at any time for any reason, with or without cause. 23

1 EXHIBIT 99.3 ORCA SYSTEMS, INC. 1999 STOCK OPTION/STOCK ISSUANCE PLAN

2 ORCA SYSTEMS, INC. 1999 STOCK OPTION/STOCK ISSUANCE PLAN 1. Purpose. This 1999 Stock Option/Stock Issuance Plan (the "Plan") is intended to promote the interests of Orca Systems, Inc. (the "Company") by giving incentives to the eligible officers and other employees and directors of and consultants and advisors to the Company, its parent (if any) and any present or future subsidiaries of the Company (collectively, "Related Corporations") through providing opportunities to acquire stock in the Company. As used herein, the terms "parent" and "subsidiary" mean "parent corporation" and "subsidiary corporation", respectively, as those terms are defined in Sections 424(e) and 424(f) or successor provisions of the Internal Revenue Code of 1986 as amended from time to time (the "Code"). 2. Structure of the Plan. The Plan permits the following separate types of grant: A. Options may be granted hereunder to purchase shares of common stock of the Company. These options may meet the requirements of Section 422 of the Code ("Incentive Stock Options" or "ISOs"); or, they may not qualify as ISOs ("Non-Qualified Options"). Both ISOs and Non-Qualified Options are sometimes referred to hereinafter as "Options". B. Awards of stock in the Company ("Awards") may be granted. C. Opportunities to make direct purchases of stock in the Company ("Purchases") may be authorized. Options, Awards and authorizations to make Purchases are sometimes referred to hereinafter as "Stock Rights". 3. Administration of the Plan. A. The Plan shall be administered by the Board of Directors of the Company (the "Board"). The Board may in its sole discretion grant Options, authorize Purchases and grant Awards, as provided in the Plan. The Board shall have full power and authority, subject to the express provisions of the Plan, to construe and interpret the Plan and all Option agreements, Purchase authorizations and Award grants thereunder, to establish, amend and rescind such rules and regulations as it may deem appropriate for the proper administration of the Plan, to determine in each case the terms and provisions which shall apply to a particular Option agreement, Purchase authorization, or Award grant, and to make all other determinations which are, in the Board's judgment, necessary or desirable for the proper administration of the Plan. The Board may correct any defect, supply any omission or reconcile any inconsistency in the Plan or in any Option agreement, Purchase authorization or Award grant in the manner and to the extent it shall, in its sole discretion, consider expedient. Decisions of the Board shall be final and binding on all parties who have an interest in the Plan or any Option, Purchase, Award, or stock

3 issuance thereunder. No director or person acting pursuant to authority delegated by the Board shall be liable for any action or determination under the Plan made in good faith. B. The Board may, to the full extent permitted by and consistent with applicable law and the Company's By-laws, and subject to Subparagraph D hereinbelow, delegate any or all of its powers with respect to the administration of the Plan to a committee (the "Committee") appointed by the Board. If a Committee has been appointed, all references in this Plan to the Board shall mean and relate to that Committee. C. Those provisions of this Plan which make express reference to Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or any successor rule ("Rule 16b-3"), or which are required in order for certain option transactions to qualify for exemption under Rule 16b-3, shall apply only to those persons required to file reports under Section 16(a) of the Exchange Act (a "Reporting Person"). D. If the Company registers any class of equity security under Section 12 of the Exchange Act, the selection of a director or an officer (as the terms "director" and "officer" are defined for purposes of Rule 16b-3) as a recipient of an option, the timing of the option grant, the exercise price of the option and the number of shares subject to the option shall be determined either (i) by the Board, if all of the Board members are disinterested persons within the meaning of Rule 16(b)(3), or (ii) by two or more directors having full authority to act in the matter, each of whom shall be such a disinterested person. 4. Eligible Employees and Others. ISOs may be granted to any employee of the Company or of any Related Corporation. No person who is not such an employee may be granted an ISO. Non-Qualified Options, Awards, and authorizations to make Purchases may be granted to any employee, officer or director of, or consultant or advisor to the Company or any Related Corporation. The granting of any Stock Right to any individual or entity shall neither entitle that individual or entity to, nor disqualify him from, participation in any other grant of Stock Rights. 5. Stock. The stock subject to Options, Awards and Purchases shall be authorized but unissued shares of common stock of the Company ("Common Stock"), or shares of Common Stock reacquired by the Company in any manner. The aggregate number of shares which may be issued under the Plan is 200,000, subject to adjustment as provided in Paragraph 14. If any Option granted under the Plan shall expire or terminate for any reason without having been exercised in full or shall cease for any reason to be exercisable in whole or in part, or if the Company shall reacquire any nonvested shares issued pursuant to Awards or Purchases, the unpurchased shares subject to such Option, or such nonvested shares so reacquired shall again be available for grants of Stock Rights under the Plan. 6. Option Agreements. As a condition to the grant of an Option, each recipient of an Option shall execute an option agreement in such form not inconsistent with the Plan as the Board shall approve. These option agreements may differ among recipients. Each option agreement with respect to an ISO shall be subject to the provisions of the Plan applicable to ISOs. The Board may, in its sole discretion, include additional provisions in option agreements, 2

4 including without limitation restrictions on transfer, repurchase rights, commitments to pay cash bonuses, to make, arrange for or guarantee loans or to transfer other property to optionees upon exercise of options, or such other provisions as shall be determined by the Board; provided, however, that such additional provisions shall not be inconsistent with any provision of the Plan and such additional provisions shall not cause any ISO granted under the Plan to fail to qualify as an incentive stock option within the meaning of Section 422 of the Code. 7. Option Exercise Price. A. Subject to Subparagraph 3D of this Plan and Subparagraphs B and C of this Paragraph 7, the purchase price per share of Common Stock deliverable upon the exercise of an Option ("exercise price") shall be determined by the Board. B. In the case of an ISO, the exercise price shall not be less than 100% of the fair market value of Common Stock, as determined by the Board, at the time of grant of such option, or less than 110% of such fair market value in the case of an ISO granted to the owner of stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or any Related Corporation (after taking into account the attribution of stock ownership rules of Section 424(d) of the Code) (a "10% Shareholder"). 8. Cancellation and New Grant of Options, Etc. The Board shall have the authority to effect, at any time and from time to time, with the consent of the affected optionees, (i) the cancellation of any or all outstanding Options and the grant in substitution therefor of new Options covering the same or different shares of Common Stock and having an exercise price per share which may be lower or higher than the exercise price per share of the canceled Options, or (ii) unless doing so would have the effect of causing an ISO to be treated as a Non-Qualified Option, the amendment of the terms of any and all outstanding Options to provide an exercise price per share which is higher or lower than the then-current exercise price per share of such outstanding Options. 9. Exercise of Options. A. Each Option granted under the Plan shall be exercisable either in full or in installments at such time or times and during such period as shall be set forth in the agreement evidencing the Option, subject to the provisions of the Plan. Unless doing so would have the effect of causing an ISO to be treated as a Non-Qualified Option, the Board may, in its sole discretion, (i) accelerate the date or dates on which all or any particular Option or Options granted under the Plan may be exercised or (ii) extend the dates during which all, or any particular, Option or Options granted under the Plan may be exercised. B. Options granted under the Plan may provide for payment of the exercise price by delivery of cash or a check payable to the order of the Company, or, to the extent (if at all) provided in the option agreement: (ii) by delivery of a recourse promissory note of the optionee bearing interest payable not less than annually at the applicable Federal rate as defined in Section 3

5 1274(d) of the Code and otherwise payable on such terms as are specified by the Board, or (ii) by any combination of the above methods of payment. 10. Option Period. Subject to earlier termination under other provisions of this Plan, each Option and all rights thereunder shall expire on such date as shall be set forth in the applicable option agreement, except that, in the case of an ISO, such expiration date (the "Expiration Date") shall not be later than ten years after the date on which the ISO is granted and, in the case of an ISO granted to a 10% Shareholder as defined in Subparagraph 7B of this Plan, such expiration date shall not be later than five years after the date on which the ISO is granted. 11. Nontransferability of Options. ISOs shall not be assignable or transferable by the optionee, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the life of the optionee, shall be exercisable only by the optionee. The foregoing restrictions shall also apply to Non-Qualified Options except to the extent otherwise provided in the agreement evidencing the Non-Qualified Option. 12. Effect of Termination of Employment or Other Relationship. Except as otherwise provided in Paragraph 10 and Subparagraph 13C with respect to ISOs, and subject to all other provisions of the Plan, the Board shall determine the period of time during which an optionee may exercise an Option following (i) the termination of the optionee's employment or other relationship with the Company or a Related Corporation or (ii) the death or disability of the optionee. Such periods shall be set forth in the agreement evidencing the Option. 13. Additional ISO Requirements. ISOs granted under the Plan are subject to the minimum exercise price rules set forth in Subparagraph 7B hereof, the option period rules of Paragraph 10 hereof, and various other restrictions set forth elsewhere in this Plan. In addition, ISOs granted under the Plan are subject to the following: A. Each ISO granted under the Plan shall, at the time of grant, be specifically designated as such in the option agreement evidencing such Option. B. In no event shall the aggregate fair market value (determined at the time an ISO is granted) of Common Stock for which ISOs granted to any employee are exercisable for the first time by such employee during any calendar year (under all stock option plans of the Company and any Related Corporation) exceed One Hundred Thousand Dollars ($100,000); provided, however, that this Subparagraph B shall have no force or effect if its inclusion in the Plan is not necessary for Options issued as ISOs to qualify as incentive stock options within the meaning of Section 422 of the Code. Any Option which would, but for its failure to satisfy the foregoing restriction, qualify as an ISO shall nevertheless be a valid Option, but to the extent of such failure it shall be deemed to be a Non-Qualified Option. C. No ISO may be exercised unless, at the time of such exercise, the optionee is, and has been continuously since the date of grant of the ISO, employed by the Company or a Related Corporation, except that: 4

6 (i) An ISO may be exercised within the period of three (3) months after the date the optionee ceases to be an employee of the Company and any Related Corporation (or within such lesser period as may be specified in the option agreement); provided, however, that the option agreement may designate a longer exercise period, in which case the exercise after such three-month period shall be treated as the exercise of a Non-Qualified Option. (ii) If the optionee dies while in the employ of the Company or a Related Corporation, or within three (3) months after the optionee ceases to be such an employee of the Company or a Related Corporation, the ISO may be exercised by the person to whom it is transferred by will or the laws of descent and distribution within the period of one (1) year after the date of death (or within such lesser period as may be specified in the option agreement). (iii) If the optionee becomes disabled (within the meaning of Section 22(e)(3) of the Code) while in the employ of the Company or a Related Corporation, the ISO may be exercised within the period of one (1) year after the date the optionee's employment ceases because of such disability (or within such lesser period as may be specified in the option agreement). For all purposes of the Plan and any agreement evidencing an Option, "employment" shall be defined in accordance with the provisions of Treasury Regulation Section 1.421-7(h) under the Code (or any successor regulations). Notwithstanding the foregoing provisions, no ISO may be exercised after its Expiration Date. 14. Adjustments. A. If, through or as a result of any merger, consolidation, sale of all or substantially all of the assets of the Company, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar transaction, (i) the outstanding shares of Common Stock are increased, decreased or exchanged for a different number or kind of shares or other securities of the Company, or (ii) additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Common Stock or other securities, an appropriate and proportionate adjustment shall be made in (a) the maximum number and kind of shares reserved for issuance under the Plan, (b) the number and kind of shares or other securities subject to any then outstanding Options under the Plan, and (c) the price for each share subject to any then outstanding Options under the Plan, without changing the aggregate purchase price as to which such Options remain exercisable. No fractional shares shall be issued under the Plan on account of any such adjustments. Notwithstanding the foregoing provisions of this Subparagraph A, no adjustment shall be made pursuant to this Paragraph 14 if such adjustment would cause any ISO granted under the Plan to fail to qualify as an incentive stock option within the meaning of Section 422 of the Code. 5

7 B. Any adjustments under this Paragraph 14 shall be made by the Board of Directors, whose determination as to what adjustments, if any, will be made and the extent thereof shall be final, binding and conclusive. 15. Rights as a Shareholder. The holder of an Option shall have no rights as a shareholder with respect to any shares covered by the option (including, without limitation, any voting rights, the right to inspect or receive the Company's balance sheets or financial statements or any rights to receive dividends or non-cash distributions with respect to such shares) until the date of issue of a stock certificate for such shares. No adjustment shall be made for dividends or other rights for which the record date is prior to the date such stock certificate is issued. 16. Merger, Consolidation, Asset Sale, Liquidation, Etc. A. Except as may otherwise be provided in the applicable option agreement, in the event of a consolidation or merger or sale of all or substantially all of the assets of the Company in which outstanding shares of Common Stock are exchanged for securities, cash or other property of any other corporation or business entity, or in the event of the liquidation of the Company, the Board, or the board of directors of any corporation assuming the obligations of the Company, shall, in its discretion, take any one or more of the following actions, as to outstanding Options: (i) provide that such Options shall be assumed, or equivalent options shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), provided, however, that any such Options substituted for ISOs shall meet the requirements of Section 424(a) of the Code; (ii) upon written notice to the optionees, provide that any and all outstanding Options shall become exercisable in full (to the extent not otherwise so exercisable) as of a specified date or time ("Accelerated Vesting Date") prior to the consummation of such transaction, and that all unexercised Options shall terminate as of a specified date or time ("Accelerated Expiration Date") following the Accelerated Vesting Date unless exercised by the optionee prior to the Accelerated Expiration Date; provided, however, that optionees shall be given a reasonable period of time within which to exercise or provide for the exercise of outstanding Options following such written notice and before the Accelerated Expiration Date; or (iii) in the event of a merger under the terms of which holders of the Common Stock of the Company will receive upon consummation thereof a cash payment for each share surrendered in the merger (the "Merger Price"), terminate each outstanding Option in exchange for a payment, made or provided for by the Company, equal in amount to the excess, if any, of the Merger Price over the per-share exercise price of each such Option, times the number of shares of Common Stock subject to such Option. The Board shall determine the fair market value of a share of Common Stock for purposes of the foregoing, and the Board's determination of such fair market value shall be final, binding and conclusive. B. The Company may grant Options under the Plan in substitution for Options held by employees of another corporation who become employees of the Company or a Related Corporation as the result of a merger or consolidation of the employing corporation with the Company or a Related Corporation, or as a result of the acquisition by the Company or a Related Corporation of property or stock of the employing corporation. The Company may direct that 6

8 substitute Options be granted on such terms and conditions as the Board considers appropriate in the circumstances. 17. Stock Restriction Agreement. As a condition to the grant of an Award or a Purchase authorization under the Plan, the recipient of the Award or Purchase authorization shall execute an agreement ("Stock Restriction Agreement") in such form not inconsistent with the Plan as may be approved by the Board. Stock Restriction Agreements may differ among recipients. Stock Restriction Agreements may include any provisions the Board determines should be included and that are not inconsistent with any provision of the Plan. 18. No Special Employment Rights. Nothing contained in the Plan or in any option agreement or other agreement or instrument executed pursuant to the provisions of the Plan shall confer upon any optionee any right with respect to the continuation of his or her employment by the Company or any Related Corporation or interfere in any way with the right of the Company or a Related Corporation at any time to terminate such employment or to increase or decrease the compensation of the optionee. 19. Other Employee Benefits. Except as to plans which by their terms include such amounts as compensation, no amount of compensation deemed to be received by an employee as a result of the grant or exercise of an Option or the sale of shares received upon such exercise, or as a result of the grant of an Award or the authorization or making of a Purchase will constitute compensation with respect to which any other employee benefits of such employee are determined, including, without limitation, benefits under any bonus, pension, profit-sharing, life insurance or salary continuation plan, except as otherwise specifically determined by the Board. 20. Amendment of the Plan. A. The Board may at any time, and from time to time, modify or amend the Plan in any respect, except as otherwise expressly provided in this Plan; provided, however, that if at any time the approval of the shareholders of the Company is required under the Code with respect to ISOs, or is required under Rule 16b-3, the Board may not effect such modification or amendment without such approval. B. The termination or any modification or amendment of the Plan shall not, without the consent of an optionee, affect the optionee's rights under an Option previously granted. With the consent of the optionee affected, the Board may amend outstanding option agreements in a manner not inconsistent with the Plan. The Board shall have the right to amend or modify (i) the terms and provisions of the Plan and of any outstanding ISO granted under the Plan to the extent necessary to qualify any or all such Options for such favorable federal income tax treatment (including deferral of taxation upon exercise) as may be afforded incentive stock options within the meaning of Section 422 of the Code, and (ii) the terms and provisions of the Plan and of any outstanding Option to the extent necessary to ensure the qualification of the Plan under Rule 16b-3. 7

9 21. Investment Representations. The Board may require any person to whom an Option is granted, as a condition of exercising such Option, and any person to whom an Award is granted or a Purchase is authorized, as a condition thereof, to give written assurances in substance and form satisfactory to the Board to the effect that such person is acquiring the Common Stock subject to the Option, Award or Purchase for such person's own account for investment and not with any present intention of selling or otherwise distributing the same, and to such other effects as the Company deems necessary or appropriate in order to comply with federal and applicable state securities laws, or with covenants or representations made by the Company in connection with any public offering of its Common Stock. 22. Compliance With Securities Laws. Each Option shall be subject to the requirement that if, at any time, counsel to the Company shall determine that the listing, registration or qualification of the shares subject to such Option upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, or that the disclosure of non-public information or the satisfaction of any other condition is necessary as a condition of, or in connection with, the issuance or purchase of shares thereunder, such Option may not be exercised, in whole or in part, unless such listing, registration, qualification, consent or approval, or satisfaction of such condition shall have been effected or obtained on conditions acceptable to the Board. Nothing herein shall be deemed to require the Company to apply for or to obtain such listing, registration or qualification, or to satisfy such condition. 23. Withholding. The Company shall have the right to deduct from payments of any kind otherwise due to the optionee any federal, state or local taxes of any kind required by law to be withheld with respect to any shares issued upon exercise of Options under the Plan or upon the grant of an Award, the making of a Purchase of Common Stock for less than its fair market value, the making of a Disqualifying Disposition (as defined in Paragraph 24), or the vesting of restricted Common Stock acquired pursuant to a Stock Right. The Board in its sole discretion may condition the exercise of an Option, the grant of an Award, the making of a Purchase, or the vesting of restricted shares acquired by exercising a Stock Right on the grantee's payment of such additional withholding taxes. 24. Notice to Company of Disqualifying Disposition. Each employee who receives an ISO must agree to notify the Company in writing immediately after the employee makes a Disqualifying Disposition, as hereinafter defined, of any Common Stock acquired pursuant to the exercise of an ISO. A Disqualifying Disposition is any disposition (including any sale) of such Common Stock before the later of (a) two (2) years after the date the employee was granted the ISO or (b) one (1) year after the date the employee acquired Common Stock by exercising the ISO. If the employee has died before such stock is sold, these holding period requirements do not apply and no Disqualifying Disposition can occur thereafter. 25. Effective Date and Duration of the Plan. A. The Plan shall become effective when adopted by the Board, but no Stock Right granted under the Plan shall become exercisable unless and until the Plan shall have been 8

10 approved by the Company's shareholders. If such shareholder approval is not obtained within twelve months after the date of the Board's adoption of the Plan, Stock Rights previously granted under the Plan shall not vest and shall terminate and shall be null and void and no Stock Rights shall be granted thereafter under the Plan. Amendments to the Plan not requiring shareholder approval shall become effective when adopted by the Board; amendments requiring shareholder approval shall become effective when adopted by the Board, but no stock Right granted after the date of such amendment shall become exercisable (to the extent that such amendment to the Plan was required to enable the Company to grant such stock Right to a particular person) unless and until such amendment shall have been approved by the Company's shareholders. If such shareholder approval is not obtained within twelve months of the Board's adoption of such amendment, any Stock Rights granted on or after the date of such amendment shall terminate and become null and void to the extent that such amendment was required to enable the Company to grant such Stock Rights to a particular person. Subject to this limitation, Stock Rights may be granted under the Plan at any time after the effective date and before the termination date of the Plan. B. Unless sooner terminated as provided elsewhere in this Plan, this Plan shall terminate upon the close of business on the day next preceding the tenth anniversary of the date of its adoption by the Board. Stock Rights outstanding on such date shall continue to have force and effect in accordance with the provisions of the instruments evidencing such Stock Rights. Adopted by the Board of Directors on February 26, 1999. 9

Exercise of Option and Provisions for Termination. (a) Vesting Schedule. Except as otherwise provided in this Agreement, and subject to all other terms and conditions of this Agreement, if the Employee has continued to be employed by the Company through any applicable date in the table below, this option may be exercised prior to the tenth anniversary of the Grant Date (hereinafter the "Expiration Date") in installments for not more than the number of shares set forth opposite such applicable date: [INSERT THE DESIRED VESTING SCHEDULE HERE.

Notwithstanding any other provision of this Agreement or the Plan, this option may not be exercised at any time on or after the Expiration Date. (b) Method of Exercise. Subject to the terms and conditions set forth in this Agreement, this option shall be exercised by the Employee's delivery of written notice of exercise to the Treasurer of the Company, specifying the number of shares to be purchased and the purchase price to be paid therefor and accompanied by payment in full in accordance with Section 4 hereof. Such exercise shall be effective upon receipt by the Treasurer of the Company of such written notice together with the required payment. The Employee may purchase less than the number of shares covered hereby, provided that no partial exercise of this option may be for any fractional share or for fewer than ______ whole shares. (c) Continuous Employment Required. Except as otherwise provided in this Section 3, this option may not be exercised unless the Employee, at the time he or she exercises this option, is, and has been at all times since the Grant Date, an employee of the Company. For all purposes of this Agreement, (i) "employee" and "employment" shall be defined in accordance with the provisions of Treasury Regulation Section 1.421-7(h) under the Code, or any successor regulations, (ii) employment by a parent or subsidiary corporation of the Company shall be deemed to be employment by the Company and (iii) if this option shall be assumed or a new option substituted therefor in a transaction to which Section 424(a) of the Code applies, employment by such assuming or substituting corporation (hereinafter a "Successor Corporation") shall be considered for all purposes of this option to be employment by the Company. As used herein, the terms "parent" and "subsidiary" mean "parent corporation" and "subsidiary corporation", respectively, as those terms are defined in Sections 424(e) and 424(f) or successor provisions of the Code. (d) Exercise Period Upon Termination of Employment. If the Employee ceases to be employed by the Company for any reason, then, except as provided in paragraphs (e) and (f) below, the right to exercise this option shall terminate on the date which is thirty (30) days after the date of cessation of employment (but in no event after the Expiration Date); provided, however, that this option shall be exercisable only to the extent that the Employee was entitled to exercise this option on the date of such cessation. Notwithstanding the foregoing, if, in the judgment of the Company, the Employee, prior to the Expiration Date, materially violates the non-competition or confidentiality provisions of any employment contract, confidentiality and nondisclosure agreement or other agreement between the Employee and the Company, the right to exercise this option shall terminate immediately upon written notice to the Employee from the Company describing such violation. (e) Exercise Period Upon Death or Disability. If the Employee dies or becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior to the Expiration Date while he or she is an employee of the Company, or if the Employee dies within three (3) months after the date on which the Employee ceases to be an employee of the Company (other than as the 2

4 result of a discharge for "cause" as specified in Paragraph (f) below), this option shall be exercisable within the period of six (6) months following the date of death or disability of the Employee (but in no event after the Expiration Date), by the Employee or by the person to whom this option is transferred by will or the laws of descent and distribution; provided, however, that this option shall be exercisable only to the extent that this option was exercisable by the Employee on the date of his or her death or disability. Except as otherwise indicated by the context, the term "Employee", as used in this Agreement, shall include the estate of the Employee, the Employee's personal representative, or any other person who acquires the right to exercise this option by bequest or inheritance or otherwise by reason of the death of the Employee or by reason of the Employee's incapacity. (f) Discharge for Cause. If the Employee, prior to the Expiration Date, is discharged by the Company for "cause" (as defined below), the right to exercise this option shall terminate immediately upon such discharge. "Cause" shall mean willful misconduct or willful failure by the Employee to perform his or her employment responsibilities in the best interests of the Company (including, without limitation, breach by the Employee of any provision of any employment, nondisclosure, non-competition or other similar agreement between the Employee and the Company), as determined by the Company, which determination shall be conclusive. The Employee shall be considered to have been discharged "for cause" if the Company determines, within thirty (30) days after the Employee's resignation, that discharge for cause was warranted. 4. Payment of Purchase Price. Payment of the purchase price for shares purchased upon exercise of this option shall, at the Employee's election, be made by delivery to the Company of cash or wire transfer or a check payable to the order of the Company in an amount equal to the purchase price per share as hereinabove set forth times the number of shares so purchased (the "exercise price"). 5. Delivery of Shares. (a) General. The Company shall, upon payment of the exercise price for the number of shares purchased and paid for, make prompt delivery of such shares to the Employee; provided, however, that if any law or regulation requires the Company to take any action with respect to such shares before the issuance thereof, then the date of delivery of such shares shall be extended for the period necessary to complete such action. (b) Listing, Registration, Qualification, Etc. This option shall be subject to the requirement that if, at any time, counsel to the Company shall determine that the listing, registration or qualification of the shares subject hereto upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, or that the disclosure of non-public information or the satisfaction of any other condition is necessary as a condition of, or in connection with, the issuance or purchase of shares hereunder, this option may not be exercised, in whole or in part, unless such listing, registration, qualification, consent or approval, disclosure or satisfaction of such other condition shall have been effected or obtained on terms acceptable to the Board of Directors of the Company. 3

5 Nothing herein shall be deemed to require the Company to apply for, effect or obtain such listing, registration, qualification, or disclosure, or to satisfy such other condition. 6. Nontransferability of Option. Except as provided in Paragraph (e) of Section 3 hereof, this option is personal and no rights granted hereunder may be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) nor shall any such rights be subject to execution, attachment or similar process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this option or of such rights contrary to the provisions hereof, or upon the levy of any attachment or similar process upon this option or such rights, this option and such rights shall, at the election of the Company, become null and void. 7. No Special Employment Rights. Nothing contained in the Plan or this Agreement shall be construed or deemed by any person under any circumstances to obligate the Company to continue the employment of the Employee for any period. 8. Rights as a Shareholder. The Employee shall have no rights as a shareholder with respect to any shares which may be purchased by exercise of this option (including, without limitation, any rights to vote or to receive dividends or other distributions with respect to such shares) unless and until a certificate representing such shares is duly issued and delivered to the Employee. No adjustment shall be made for dividends or other rights for which the record date is prior to the date such stock certificate is issued. 9. Adjustment Provisions. (a) General. If through, or as a result of, any merger, consolidation, sale of all or substantially all of the assets of the Company, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar transaction, (i) the outstanding shares of Common Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities of the Company, or (ii) additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Common Stock or other securities, the Employee shall, with respect to this option or any unexercised portion hereof, be entitled to the rights and benefits, and be subject to the limitations, set forth in Paragraph 14 of the Plan. (b) Board Authority to Make Adjustments. Any adjustments under this Section 9 shall be made by the Board of Directors of the Company, whose determination as to what adjustments, if any, will be made and the extent thereof will be final, binding and conclusive. No fractional shares will be issued with respect to this option on account of any such adjustments. (c) Limits on Adjustments. No adjustment shall be made under this Section 9 which would, for purposes of any applicable provision of the Code, constitute a modification, extension or renewal of this option or a grant of additional benefits to the Employee. 10. Mergers, Consolidations, Asset Sales, Liquidations, Etc. In the event of a consolidation or merger or sale of all or substantially all of the assets of the Company in which 4

6 outstanding shares of Common Stock are exchanged for securities, cash or other property of any other corporation or business entity, or in the event of the liquidation of the Company, prior to the Expiration Date or other termination of this option, the Employee shall, with respect to this option or any unexercised portion hereof, be entitled to the rights and benefits, and be subject to the limitations, set forth in Paragraph 16 of the Plan. 11. Withholding of Taxes. The Company's obligation to deliver shares upon the exercise of this option shall be subject to the Employee's satisfaction of all applicable federal, state and local income and employment tax withholding requirements as described in Paragraph 23 of the Plan. Without limiting the generality of the foregoing, if the Company in its discretion determines that it is obligated to withhold tax with respect to a Disqualifying Disposition (as defined in Section 12 hereof), the Employee agrees that the Company may withhold from the Employee's wages the appropriate amount of federal, state and local withholding taxes attributable to such Disqualifying Disposition. If any portion of this option is treated as a Non-Qualified Option, the Employee agrees that the Company may withhold from the Employee's wages the appropriate amount of federal, state and local withholding taxes attributable to the Employee's exercise of such Non-Qualified Option. At the Company's discretion, the amount required to be withheld may be withheld in cash from such wages, or otherwise as may be permitted under the Plan. The Employee further agrees that, if the Company does not withhold an amount from the Employee's wages sufficient to satisfy the Company's withholding obligation or if such obligation is not otherwise satisfied, as determined by the Company, the Employee will reimburse the Company on demand, in cash, for the amount underwithheld. 12. Holding Period Requirements for Incentive Stock Option Shares. It is understood and intended that this option shall qualify as an "incentive stock option" as defined in Section 422 of the Code (an "ISO"). Accordingly, the Employee understands that in order to obtain the beneficial tax treatment accorded an ISO, no sale or other disposition may be made of any shares acquired upon exercise of the option within one (1) year after the day of the transfer of such shares to the Employee, nor within two (2) years after the Grant Date. If the Employee intends to dispose, or does dispose (whether by sale, exchange, gift, transfer or otherwise), of any such shares within either of said periods, he or she will notify the Company in writing within ten (10) days after such disposition (a "Disqualifying Dispositions"). 13. Investment Representations, Warranties and Covenants; Legends. (a) Representations. The Employee represents, warrants and covenants that: (i) Any shares purchased upon exercise of this option shall be acquired for the Employee's account for investment only and not with a view to, or for sale in connection with, any distribution of the shares in violation of the Securities Act of 1933 (the "Securities Act") or any rule or regulation under the Securities Act. (ii) The Employee has had such opportunity as he or she has deemed adequate to obtain from representatives of the Company such information as is necessary to permit the Employee to evaluate the merits and risks of his or her investment in the Company. 5

7 (iii) The Employee is able to bear the economic risk of holding shares acquired pursuant to the exercise of this option for an indefinite period. (iv) The Employee understands that (A) the shares acquired pursuant to the exercise of this option will not be registered under the Securities Act and are "restricted securities" within the meaning of Rule 144 under the Securities Act; (B) such shares cannot be sold, transferred or otherwise disposed of unless they are subsequently registered under the Securities Act or an exemption from registration is then available; (C) in any event, an exemption from registration under Rule 144 or otherwise under the Securities Act may not be available for at least two years and even then will not be available unless a public market then exists for the Common Stock, adequate information concerning the Company is then available to the public and other terms and conditions of Rule 144 are complied with; and (D) there is now no registration statement on file with the Securities and Exchange Commission with respect to any stock of the Company and the Company has no obligation or current intention to register any shares acquired pursuant to the exercise of this option under the Securities Act. (v) The Employee agrees that, if the Company offers for the first time any of its Common Stock for sale pursuant to a registration statement under the Securities Act, the Employee will not, without the prior written consent of the Company, publicly offer, sell, contract to sell or otherwise dispose of, directly or indirectly, any shares purchased upon exercise of this option for a period of ninety (90) days, or such longer period as the Company may reasonably require, after the effective date of such registration statement. (vi) The Employee's principal residence is at the address set forth below on the signature page. The Employee shall promptly notify the Company of any change in the Employee's principal residence. By making payment upon any exercise of this option, in whole or in part, the Employee shall be deemed to have reaffirmed, as of the date of such payment, the representations made in this Section 13. (b) Legends on Stock Certificates. All stock certificates representing shares of Common Stock issued to the Employee upon exercise of this option shall have affixed thereto legends substantially in the following forms, in addition to any other legends required by applicable state law: "THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT WITH RESPECT TO THE SHARES EVIDENCED BY THIS CERTIFICATE, FILED AND MADE EFFECTIVE UNDER THE SECURITIES ACT OF 1933, OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY TO THE EFFECT THAT REGISTRATION UNDER SUCH ACT IS NOT REQUIRED." 6

8 "THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER CONTAINED IN AN OPTION AGREEMENT, A COPY OF WHICH WILL BE FURNISHED UPON REQUEST BY THE ISSUER." 14. Transfer and Other Restrictions; Company's Purchase Right. Except as set forth in this Section 14, no disposition (whether by sale, exchange, gift, transfer or otherwise) may be made of any shares acquired upon exercise of this option, other than by will or the laws of descent and distribution. (a) First Refusal Rights. (i) If the Employee or the Employee's successor in interest desires to sell all or any part of the shares acquired under this option (including any securities received in respect thereof pursuant to recapitalizations and the like), and an offeror (the "Offeror") has made an offer therefor, which offer the Employee desires to accept, the Employee shall: (y) obtain in writing an irrevocable and unconditional bona fide offer (the "Bona Fide Offer") for the purchase thereof from the Offeror; and (z) give written notice (the "Option Notice") to the President of the Company setting forth the Employee's desire to sell such shares, which Option Notice shall be accompanied by a photocopy of the original executed Bona Fide Offer and shall set forth at least the name and address of the Offeror and the price and terms of the Bona Fide Offer. Upon receipt of the Option Notice, the Company shall have an option to purchase any or all of the shares specified in the Option Notice, such option to be exercisable by giving, within thirty (30) days after receipt of the Option Notice, a written counter-notice to the Employee. If the Company elects to purchase, the Employee shall be obligated to sell to the Company such shares at the price and terms indicated in the Bona Fide Offer within sixty (60) days from the date of receipt by the Company of the Option Notice. The Company's purchase rights under this Section 14 are assignable by the Company. (ii) Subject to Paragraph 14(b) below, the Employee may sell, pursuant to the terms of the Bona Fide Offer, any or all of such shares not purchased by the Company or which the Company does not elect to purchase in the manner set forth hereinabove after the expiration of the 30-day period during which the Company may give the aforesaid counter-notice; provided, however, that the Employee may not sell such shares to the Offeror if the Offeror is (w) a competitor of the Company, or (x) a person that controls, is controlled by or under common control with a competitor of the Company, or (y) a member of management of a competitor of the Company (any person described in clauses (w) through (y) being hereinafter referred to as a "Competitor") or (z) a person or entity to which the Board of Directors determines, in its sole discretion, that a transfer of shares of the Company would be against the Company's best interest, and the Company gives to the Employee, within thirty (30) days of its receipt of the Option Notice, written notice stating that the Employee shall not sell the shares to the Offeror; and provided, further, that prior to the sale of any such shares to the Offeror, the Offeror shall execute an agreement with the Company under which the Offeror agrees not to become a Competitor of the Company and further agrees to be subject to the restrictions set forth in this Agreement. If any or all of such shares are not sold pursuant to a Bona Fide Offer within the time permitted above, the unsold shares shall remain subject to the terms of this Agreement. 7

9 (iii) The first refusal rights of the Company set forth above shall remain in effect until the closing of an initial underwritten public offering of the Company's Common Stock pursuant to a registration statement filed under the Securities Act of 1933, as amended, or a successor statute, at which time the first refusal rights set forth herein will automatically expire. (b) Company's S Corporation Status. (i) The Employee understands and acknowledges that the Company has made an election under Section 1362(a) of the Code to be taxed as an "S corporation" ("S Election"), that this tax status is in the best interests of the Company and its shareholders, and that the Company's S Election may be terminated and such status may be lost as a result of any transfer of the Company's stock to an ineligible shareholder, or by the Company having more than seventy-five (75) shareholders, or by certain other actions or events. Accordingly, the Employee agrees that the Employee will not: (A) Transfer any share of stock of the Company unless (y) in the opinion of counsel to the Company such transfer will not adversely affect the Company's S Election, and (z) the transferee consents in writing to be bound by the provisions of this Section 14 and consents in writing to the continuation of the Company's S Election. Any attempt by the Employee to transfer any of the shares of stock received as a result of the exercise of this option in contravention of the foregoing shall be null and void ab initio. Nothing contained herein shall be construed to permit a transfer of stock of the Company if the transfer is otherwise restricted by the terms of this Agreement, by any governmental statute, regulation or rule, or by the terms of any other agreement to which the Employee is a party. (B) File any document with the Internal Revenue Service, or take any other action, resulting in the termination of the Company's S Election. (C) Fail to sign or file any consent or other document with the Internal Revenue Service deemed necessary by counsel to the Company for the preservation of the Company's S Election. (D) Fail to take any other action from time to time considered necessary or advisable by counsel to the Company for the preservation of the Company's S Election. (E) Change his or her residence or take any other action such that the Employee would not be either a resident of the United States or a citizen of the United States without giving thirty (30) days prior written notice to the Company and offering the Company the right to repurchase all of his or her shares of Common Stock at a price determined pursuant to Section 14(c)(ii) hereof before making such change of residence or citizenship. (ii) In the event of an inadvertent termination of the Company's S Election, whether as a result of a transfer of stock or for any other reason, and prior to any 8

10 termination of said election by a valid written revocation under Section 1362(d)(1) of the Code, the Employee agrees to make any necessary adjustments under Section 1362(f)(4) of the Code in order to continue the treatment of the Company as an S corporation under the Code. The Employee agrees that any such adjustment shall be effective as of the date of such inadvertent termination. (iii) The Employee agrees to indemnify and hold harmless the Company and the Company's other shareholders from any and all damages, losses or other financial injuries sustained by it or them as a result of the Employee's failure to comply with the terms and provisions of this paragraph (b). (iv) The Company may choose to terminate its S Election at any time without any notice to the Employee. The Company shall have no liability to the Employee for any termination of its S Election, regardless of the reason for such termination. (c) Option to Purchase Upon Termination of Business Relationship. (i) Option. If the Employee ceases to be employed by the Company for any reason, the Company shall have the option, exercisable at any time within thirty (30) days after the later of the date on which the Employee's employment terminates or the expiration of the applicable exercise period set forth in Section 3(d), (e) or (f) above, to purchase all or any part of the Employee's shares purchased under this option. The Company may assign this right to purchase in its sole discretion. The Company or its assignee(s) shall exercise the foregoing option by sending written notice to the Employee within the thirty (30)-day period. (ii) Purchase Price. The purchase price of any shares to be sold to the Company and/or its assigns under this paragraph (c) shall be the fair market value thereof as determined by the Board of Directors as of the date on which the Employee's employment terminated. Such purchase price shall be payable in eight (8) equal quarterly payments with interest at the applicable Federal rate, as defined in Section 1274(d) of the Code, with the first payment to be made at the closing of a purchase and sale of shares pursuant to Subparagraph (iii) below, and each subsequent payment to be made at three (3)-month intervals. (iii) Settlement. The closing of a purchase and sale of shares under this Paragraph (c) shall take place at the principal office of the Company at such time and date as shall be mutually agreed between the Company and the Employee; provided, that if the parties cannot reach such agreement, settlement shall be ninety (90) days after the date of termination of the Employee's employment with the Company (or if such day is a holiday, the first business day thereafter). At the closing, the Employee shall deliver to the Company (i) the certificate or certificates representing the shares held by such Employee, duly endorsed for transfer, or (ii) if such certificate or certificates are already in the Company's possession, such duly endorsed stock powers as the Company may request to permit it to record the repurchase by the Company on the records of the Company. 9

11 15. Miscellaneous. (a) Except as otherwise expressly provided herein, this Agreement may not be amended or otherwise modified unless evidenced in writing and signed by the Company and the Employee. (b) All notices under this Agreement shall be delivered by hand, sent by commercial overnight courier service or sent by registered or certified mail, return receipt requested, and first-class postage prepaid, to the parties at their respective addresses set forth beneath their names below or at such other address as may be designated in a notice by either party to the other. Notwithstanding the foregoing, any notice sent to such an address in a country other than that from which the notice is sent may be sent by telefax, telegram or commercial air courier. (c) Any reference in this Agreement to a Section of the Code shall refer to that Section as it reads as of the date of this Agreement and as it may be amended from time to time, and to any successor provision. (d) Each provision of this Agreement shall be considered separable. The invalidity or unenforceability of any provision shall not affect the other provisions, and this Agreement shall be construed in all respects as if such invalid or unenforceable provision were omitted. (e) Sections 12, 13, 14 and 15 hereof shall survive any termination of this Agreement. (f) This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts. (g) The failure of the Company or the Employee to insist upon strict performance of any provision hereunder, irrespective of the length of time for which such failure continues, shall not be deemed a waiver of such party's right to demand strict performance at any time in the future. No consent or waiver, express or implied, to or of any breach or default in the performance of any obligation or provision hereunder shall constitute a consent or waiver to or of any other breach or default in the performance of the same or any other obligation hereunder. 10

2 ORCA SYSTEMS, INC. NON-QUALIFIED STOCK OPTION AGREEMENT Orca Systems, Inc., a Delaware corporation (the "Company"), hereby grants this ___ day of (the "Grant Date"), to <> <> (the "Optionee"), an option to purchase a maximum of __________________ (_______) shares of the Company's Common Stock, one cent ($.01) par value per share, (the "Common Stock"), at the price of $_____ per share, on the following terms and conditions: 1. Stock Option Grant. (a) Reference is hereby made to the Company's 1999 Stock Option/Stock Issuance Plan (the "Plan"). The Optionee and the Company agree that this option is not issued pursuant to the Plan. The Optionee and the Company agree, however, that, other than the provision of the Plan relating to the number of shares of Common Stock which may be issued thereunder, the terms and conditions thereof are incorporated herein by this reference and shall apply hereto. Unless the context otherwise requires, terms used herein shall have the same meaning as in the Plan. Determinations made pursuant to the Plan in connection with this option shall be governed by the Plan as it exists on the date of this option agreement ("Agreement"). (b) The granting of this option shall be subject to receipt by the Company of the Company's current form of non-disclosure, non-competition and developments agreement, executed and delivered by the Optionee. 2. Grant as Non-Qualified Option; Other Options. This option is intended to be a Non-Qualified Option; it is not intended to qualify as an incentive stock option within the meaning of Section 422 of the Internal Revenue Code of 1986 (the "Code"). This option is in addition to any other options heretofore or hereafter granted to the Optionee by the Company, but a duplicate original of this instrument shall not effect the grant of another option. 3. Exercise of Option and Provisions for Termination. (a) Vesting Schedule. Except as otherwise provided in this Agreement, and subject to all other terms and conditions of this Agreement, if the Optionee has continued to have a Business Relationship, as that term is defined in Paragraph (c) of this Section 3, with the Company through any applicable date in the table below, this option may be exercised prior to the tenth anniversary of the Grant Date (hereinafter the "Expiration Date") in installments for not more than the number of shares set forth opposite such applicable date: As of the Grant Date 0 shares As of the First Anniversary of the Grant Date ________ shares As of the Second Anniversary of the Grant Date an additional _______ shares As of the Third Anniversary of the Grant Date an additional _______ shares As of the Fourth Anniversary of the Grant Date an additional _______ shares

3 The right of exercise shall be cumulative so that if the option is not exercised to the maximum extent permissible as of an applicable date, it shall be exercisable, in whole or in part, with respect to all shares not so purchased at any time prior to the Expiration Date or the earlier termination of this option. Notwithstanding any other provision of this Agreement or the Plan, this option may not be exercised at any time on or after the Expiration Date. (b) Method of Exercise. Subject to the terms and conditions set forth in this Agreement, this option shall be exercised by the Optionee's delivery of written notice of exercise to the Treasurer of the Company, specifying the number of shares to be purchased and the purchase price to be paid therefor and accompanied by payment in full in accordance with Section 4 hereof. Such exercise shall be effective upon receipt by the Treasurer of the Company of such written notice together with the required payment. The Optionee may purchase less than the number of shares covered hereby, provided that no partial exercise of this option may be for any fractional share or for fewer than 500 whole shares. (c) Continuous Business Relationship Required. Except as otherwise provided in this Section 3, this option may not be exercised unless the Optionee, at the time the Optionee exercises this option, is and has been at all times since the Grant Date, an employee, officer or director of, or consultant or advisor to the Company (any of such relationships, a "Business Relationship"). (d) Exercise Period Upon Termination of Business Relationship. If the Optionee ceases to have a Business Relationship with the Company, then, except as provided in paragraphs (e) and (f) below, the right to exercise this option shall terminate on the date which is thirty (30) days after the date on which the Optionee ceases to have any Business Relationship with the Company (but in no event after the Expiration Date); provided, however, that this option shall be exercisable only to the extent that the Optionee was entitled to exercise this option on the date of such cessation. Notwithstanding the foregoing, if, in the judgment of the Company, the Optionee, prior to the Expiration Date, materially violates the non-competition or confidentiality provisions of any employment contract, confidentiality and nondisclosure agreement or other agreement between the Optionee and the Company, the right to exercise this option shall terminate immediately upon written notice to the Optionee from the Company describing such violation. (e) Exercise Period Upon Death or Disability. If the Optionee is a natural person who dies or becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior to the Expiration Date while he or she has a Business Relationship with the Company, or if such an Optionee dies within three (3) months after the date on which he or she ceases to have a Business Relationship with the Company (other than as the result of a discharge for "cause" as specified in Paragraph (f) below), this option shall be exercisable within the period of six (6) months following the date of death or disability of the Optionee (but in no event after the Expiration Date), by the Optionee or by the person to whom this option is transferred by will or the laws of descent and distribution; provided, however, that this option shall be exercisable only to the extent that this option was exercisable by the Optionee on the date of his or her death or disability. Except as otherwise indicated by the context, the term "Optionee", as used in this 2

4 Agreement, shall include the estate of the Optionee, the Optionee's personal representative, or any other person who acquires the right to exercise this option by bequest or inheritance or otherwise by reason of the death of the Optionee or by reason of the Optionee's incapacity. (f) Discharge for Cause. If the Optionee, prior to the Expiration Date, is discharged by the Company for "cause" (as defined below), the right to exercise this option shall, terminate immediately upon such discharge. "Cause" shall mean willful misconduct or willful failure to perform the Optionee's responsibilities in the best interests of the Company (including, without limitation, breach by the Optionee of any provision of any employment, nondisclosure, non-competition or other similar agreement between the Optionee and the Company), as determined by the Company, which determination shall be conclusive. The Optionee shall be considered to have been discharged "for cause" if the Company determines, within thirty (30) days after the Optionee's resignation, that discharge for cause was warranted. 4. Payment of Purchase Price. Payment of the purchase price for shares purchased upon exercise of this option shall be made by delivery to the Company of cash or wire transfer or a check payable to the order of the Company in an amount equal to the purchase price per share as hereinabove set forth times the number of shares so purchased (the "exercise price"). 5. Delivery of Shares. (a) General. The Company shall, upon payment of the exercise price for the number of shares purchased and paid for, make prompt delivery of such shares to the Optionee; provided, however, that if any law or regulation requires the Company to take any action with respect to such shares before the issuance thereof, then the date of delivery of such shares shall be extended for the period necessary to complete such action. (b) Listing, Registration, Qualification, Etc. This option shall be subject to the requirement that if, at any time, counsel to the Company shall determine that the listing, registration or qualification of the shares subject hereto upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, or that the disclosure of nonpublic information or the satisfaction of any other condition is necessary as a condition of, or in connection with, the issuance or purchase of shares hereunder, this option may not be exercised, in whole or in part, unless such listing, registration, qualification, consent or approval, disclosure or satisfaction of such other condition shall have been effected or obtained on terms acceptable to the Board of Directors of the Company. Nothing herein shall be deemed to require the Company to apply for, effect or obtain such listing, registration, qualification, or disclosure, or to satisfy such other condition. 6. Nontransferability of Option. Except as provided in Paragraph (e) of Section 3 hereof, this option is personal and no rights granted hereunder may be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) nor shall any such rights be subject to execution, attachment or similar process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this option or of such rights contrary to the provisions 3

5 hereof, or upon the levy of any attachment or similar process upon this option or such rights, this option and such rights shall, at the election of the Company, become null and void. 7. No Special Employment or Other Rights. Nothing contained in the Plan or this Agreement shall be construed or deemed by any person under any circumstances to obligate the Company to continue any employment or other Business Relationship of the Optionee for any period. 8. Rights as a Shareholder. The Optionee shall have no rights as a shareholder with respect to any shares which may be purchased by exercise of this option (including, without limitation, any rights to vote or to receive dividends or other distributions with respect to such shares) unless and until a certificate representing such shares is duly issued and delivered to the Optionee. No adjustment shall be made for dividends or other rights for which the record date is prior to the date such stock certificate is issued. 9. Adjustment Provisions. (a) General. If through, or as a result of, any merger, consolidation, sale of all or substantially all of the assets of the Company, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar transaction, (i) the outstanding shares of Common Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities of the Company, or (ii) additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Common Stock or other securities, the Optionee shall, with respect to this option or any unexercised portion hereof, be entitled to the rights and benefits, and be subject to the limitations, set forth in Paragraph 14 of the Plan. (b) Board Authority to Make Adjustments. Any adjustments under this Section 9 will be made by the Board of Directors of the Company, whose determination as to what adjustments, if any, will be made and the extent thereof will be final, binding and conclusive. No fractional shares will be issued with respect to this option on account of any such adjustments. 10. Mergers, Consolidations, Asset, Sales, Liquidations, Etc. In the event of a consolidation or merger or sale of all or substantially all of the assets of the Company in which outstanding shares of Common Stock are exchanged for securities, cash or other property of any other corporation or business entity, or in the event of the liquidation of the Company, prior to the Expiration Date or other termination of this option, the Optionee shall, with respect to this option or any unexercised portion hereof, be entitled to the rights and benefits, and be subject to the limitations, set forth in Paragraph 16 of the Plan. 11. Withholding of Taxes. The Company's obligation to deliver shares upon the exercise of this option shall be subject to the Optionee's satisfaction of all applicable federal, state and local income and employment tax withholding requirements as described in Paragraph 23 of the Plan. Without limiting the generality of the foregoing, the Optionee agrees that the Company may withhold from the Optionee's wages the appropriate amount of federal, state and local 4

6 withholding taxes attributable to the Optionee's exercise of the option. At the Company's discretion, and to the extent permitted by the Plan, the amount required to be withheld may be withheld in cash from such wages, or otherwise as may be permitted under the Plan. The Optionee further agrees that, if the Company does not withhold an amount from the Optionee's wages sufficient to satisfy the Company's withholding obligation or if such obligation is not otherwise satisfied, as determined by the Company, the Optionee will reimburse the Company on demand, in cash, for the amount underwithheld. 12. Investment Representations, Warranties and Covenants; Legends. (a) Representations. The Optionee represents, warrants and covenants that: (i) Any shares purchased upon exercise of this option shall be acquired for the Optionee's account for investment only and not with a view to, or for sale in connection with, any distribution of the shares in violation of the Securities Act of 1933 (the "Securities Act") or any rule or regulation under the Securities Act. (ii) The Optionee has had such opportunity as the Optionee has deemed adequate to obtain from representatives of the Company such information as is necessary to permit the Optionee to evaluate the merits and risks of the Optionee's investment in the Company. (iii) The Optionee is able to bear the economic risk of holding shares acquired pursuant to the exercise of this option for an indefinite period. (iv) The Optionee understands that (A) the shares acquired pursuant to the exercise of this option will not be registered under the Securities Act and are "restricted securities" within the meaning of Rule 144 under the Securities Act; (B) such shares cannot be sold, transferred or otherwise disposed of unless they are subsequently registered under the Securities Act or an exemption from registration is then available; (C) in any event, an exemption from registration under Rule 144 or otherwise under the Securities Act may not be available for at least two years and even then will not be available unless a public market then exists for the Common Stock, adequate information concerning, the Company is then available to the public and other terms and conditions of Rule 144 are complied with; and (D) there is now no registration statement on file with the Securities and Exchange Commission with respect to any stock of the Company and the Company has no obligation or current intention to register any shares acquired pursuant to the exercise of this option under the Securities Act. (v) The Optionee agrees that, if the Company offers for the first time any of its Common Stock for sale pursuant to a registration statement under the Securities Act, the Optionee will not, without the prior written consent of the Company, publicly offer, sell, contract to sell or otherwise dispose of, directly or indirectly, any shares purchased upon exercise of this option for a period of ninety (90) days, or such longer period as the Company may reasonably require, after the effective date of such registration statement. 5

By making payment upon any exercise of this option, in whole or in part, the Optionee shall be deemed to have reaffirmed, as of the date of such payment, the representations made in this Section 12. (b) Legends on Stock Certificates. All stock certificates representing shares of Common Stock issued to the Optionee upon exercise of this option shall have affixed thereto legends substantially in the following forms, in addition to any other legends required by applicable state law: "THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT WITH RESPECT TO THE SHARES EVIDENCED BY THIS CERTIFICATE, FILED AND MADE EFFECTIVE UNDER THE SECURITIES ACT OF 1933, OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY TO THE EFFECT THAT REGISTRATION UNDER SUCH ACT IS NOT REQUIRED." "THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER CONTAINED IN AN OPTION AGREEMENT, A COPY OF WHICH WILL BE FURNISHED UPON REQUEST BY THE ISSUER." 13. Transfer and Other Restrictions; Company's Purchase Rights. Except as set forth in this Section 13, no disposition (whether by sale, exchange, gift, transfer or otherwise) may be made of any shares acquired upon exercise of this option, other than by will or the laws of descent and distribution. (a) First Refusal Rights. (i) If the Optionee or the Optionee's successor in interest desires to sell all or any part of the shares acquired under this option (including any securities received in respect thereof pursuant to recapitalizations and the like), and an offeror (the "Offeror") has made an offer therefor, which offer the Optionee desires to accept, the Optionee shall: (y) obtain in writing an irrevocable and unconditional bona fide offer (the "Bona Fide Offer") for the purchase thereof from the Offeror; and (z) give written notice (the "Option Notice") to the President of Company setting forth the Optionee's desire to sell such shares, which Option Notice shall be accompanied by a photocopy of the original executed Bona Fide Offer and shall set forth at least the name and address of the Offeror and the price and terms of the Bona Fide Offer. Upon receipt of the Option Notice, the Company shall have an option to purchase any or all of the shares specified in the Option Notice, such option to be exercisable by giving, within thirty (30) days after receipt of the Option Notice, a written counter-notice to the Optionee. If the Company elects to purchase, the Optionee shall be obligated to sell to the Company such shares at the price 6

8 and terms indicated in the Bona Fide Offer within sixty (60) days from the date of receipt by the Company of the Option Notice. The Company's purchase rights under this Section 13 are assignable by the Company. (ii) Subject to the provisions of Paragraph (b) of this Section 13, the Optionee may sell, pursuant to the terms of the Bona Fide Offer, any or all of such shares not purchased by the Company or which the Company does not elect to purchase in the manner set forth hereinabove after the expiration of the 30-day period during which the Company may give the aforesaid counter-notice; provided, however, that the Optionee may not sell such shares to the Offeror if the Offeror is (A) a competitor of the Company, or (B) a person that controls, is controlled by or under common control with a competitor of the Company, or (C) a member of management of a competitor of the Company (any person described in clauses (A) through (C) being hereinafter referred to as a "Competitor") or (D) a person or entity to which the Board of Directors determines in its sole discretion, that a transfer of shares of the Company would be against the Company's best interest, and the Company gives to the Optionee, within thirty (30) days of its receipt of the Option Notice, written notice stating that the Optionee shall not sell the shares to the Offeror; and provided, further, that prior to the sale of any such shares to the Offeror, the Offeror shall execute an agreement with the Company under which the Offeror agrees not to become a Competitor of the Company and further agrees to be subject to the restrictions set forth in this Agreement. If any or all of such shares are not sold pursuant to a Bona Fide Offer within the time permitted above, the unsold shares shall remain subject to the terms of this Agreement. (iii) The first refusal rights of the Company set forth above shall remain in effect until the closing of an initial underwritten public offering of the Company's Common Stock pursuant to a registration statement filed under the Securities Act of 1933, as amended, or a successor statute, at which time the first refusal rights set forth herein will automatically expire. (b) Company's S Corporation Status. (i) The Optionee understands and acknowledges that the Company has made an election under Section 1362(a) of the Code to be taxed as an "S corporation" ("S Election"), that this tax status is in the best interests of the Company and its shareholders, and that the Company's S Election may be terminated and such status may be lost as a result of any transfer of the Company's stock to an ineligible shareholder, or by the Company having more than seventy-five (75) shareholders, or by certain other actions or events. Accordingly, the Optionee agrees that the Optionee will not: (A) Transfer any share of stock of the Company unless (y) in the opinion of counsel to the Company such transfer will not adversely affect the Company's S Election, and (z) the transferee consents in writing to be bound by the provisions of this Section 13 and consents in writing to the continuation of the Company's S Election. Any attempt by the Optionee to transfer any of the shares of stock received as a result of the exercise of this option in contravention of the foregoing shall be null and void ab initio. Nothing contained herein shall be construed to permit a transfer of stock of the Company if the transfer is otherwise restricted by 7

9 the terms of this Agreement, by any governmental statute, regulation or rule, or by the terms of any other agreement to which the Optionee is a party. (B) File any document with the Internal Revenue Service, or take any other action, resulting in the termination of the Company's S Election. (C) Fail to sign or file any consent or other document with the Internal Revenue Service deemed necessary by counsel to the Company for the preservation of the Company's S Election. (D) Fail to take any other action from time to time considered necessary or advisable by counsel to the Company for the preservation of the Company's S Election. (E) Change his or her residence or take any other action such that the Optionee would not be either a resident of the United States or a citizen of the United States without giving thirty (30) days prior written notice to the Company and offering the Company the right to repurchase all of his or her shares of Common Stock at a price determined pursuant to Section 13(c)(ii) hereof before making such change of residence or citizenship. (ii) In the event of an inadvertent termination of the Company's S Election, whether as a result of a transfer of stock or for any other reason, and prior to any termination of said election by a valid written revocation under Section 1362(d)(1) of the Code, the Optionee agrees to make any necessary adjustments under Section 1362(f)(4) of the Code in order to continue the treatment of the Company as an S corporation under the Code. The Optionee agrees that any such adjustment shall be effective as of the date of such inadvertent termination. (iii) The Optionee agrees to indemnify and hold harmless the Company and the Company's other shareholders from any and all damages, losses or other financial injuries sustained by it or them as a result of the Optionee's failure to comply with the terms and provisions of this Paragraph (b). (iv) The Company may choose to terminate its S Election at any time without any notice to the Optionee. The Company shall have no liability to the Optionee for any termination of its S Election, regardless of the reason for such termination. (c) Option to Purchase Upon Termination of Business Relationship. (i) Option. If the Optionee ceases to have a Business Relationship (as defined in Section 3(c)) with the Company for any reason, the Company shall have the option, exercisable at any time within thirty (30) days after the later of the date on which the Optionee's Business Relationship with the Company terminates or the expiration of the applicable exercise period set forth in Section 3(d), or (e) or (f) above, to purchase all or any part of the Optionee's shares purchased under this option. The Company may assign this right to purchase in its sole 8

10 discretion. The Company or its assignee(s) shall exercise the foregoing option by sending written notice to the Optionee within the thirty (30)-day period. (ii) Purchase Price. The purchase price of any shares to be sold to the Company and/or its assigns under this paragraph (c) shall be the fair market value thereof as determined by the Board of Directors as of the date on which the Optionee's Business Relationship with the Company terminated. Such purchase price shall be payable in eight (8) equal quarterly payments with interest at the applicable Federal rate, as defined in Section 1274(d) of the Code, with the first payment to be made at the closing of a purchase and sale of shares pursuant to Subparagraph (iii) below, and each subsequent payment to be made at [three (3)-month intervals. (iii) Settlement. The closing of a purchase and sale of shares under this Paragraph (c) shall take place at the principal office of the Company at such time and date as shall be mutually agreed between the Company and the Optionee; provided, that if the parties cannot reach such agreement, settlement shall be ninety (90) days after the date of termination of the Optionee's Business Relationship with the Company (or if such day is a holiday, the first business day thereafter). At the closing, the Optionee shall deliver to the Company (i) the certificate or certificates representing the shares held by such Optionee, duly endorsed for transfer, or (ii) if such certificate or certificates are already in the Company's possession, such duly endorsed stock powers as the Company may request to permit it to record the repurchase by the Company on the records of the Company. 14. Miscellaneous. (a) Except as otherwise expressly provided herein, this Agreement may not be amended or otherwise modified unless evidenced in writing and signed by the Company and the Optionee. (b) All notices under this Agreement shall be delivered by hand, sent by commercial overnight courier service or sent by registered or certified mail, return receipt requested, and first-class postage prepaid, to the parties at their respective addresses set forth beneath their names below or at such other address as may be designated in a notice by either party to the other. Notwithstanding the foregoing, any notice sent to such an address in a country other than that from which the notice is sent may be sent by telefax, telegram or commercial air courier. (c) Any reference in this Agreement to a Section of the Code shall refer to that Section as it reads as of the date of this Agreement and as it may be amended from time to time, and to any successor provision. (d) Each provision of this Agreement shall be considered separable. The invalidity or unenforceability of any provision shall not affect the other provisions, and this Agreement shall be construed in all respects as if such invalid or unenforceable provision were omitted. 9

11 (e) Sections 12, 13 and 14 hereof shall survive any termination of this Agreement. (f) This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts. (g) The failure of the Company or the Optionee to insist upon strict performance of any provision hereunder, irrespective of the length of time for which such failure continues, shall not be deemed a waiver of such party's right to demand strict performance at any time in the future. No consent or waiver, express or implied, to or of any breach or default in the performance of any obligation or provision hereunder shall constitute a consent or waiver to or of any other breach or default in the performance of the same or any other obligation hereunder.

1 EXHIBIT 99.6 FORM OF STOCK OPTION ASSUMPTION AGREEMENT FOR ORCA SYSTEMS, INC.

2 NETWORK APPLIANCE, INC. STOCK OPTION ASSUMPTION AGREEMENT ORCA SYSTEMS, INC. 1999 STOCK OPTION/STOCK ISSUANCE PLAN OPTIONEE: _______________, STOCK OPTION ASSUMPTION AGREEMENT effective as of the 14th day of June, 2000. WHEREAS, the undersigned individual ("Optionee") holds one or more outstanding options to purchase shares of the common stock of Orca Systems, Inc., a Delaware corporation ("Orca"), which were granted to Optionee under Orca Systems, Inc. 1999 Stock Option/Stock Issuance Plan (the "Plan"). WHEREAS, each of those options is evidenced by a Stock Option Agreement (the "Option Agreement") issued to Optionee under the Plan. WHEREAS, Orca has been acquired by Network Appliance, Inc., a California corporation ("NetApp"), through the merger of Orca Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of NetApp ("Merger Sub"), with and into Orca (the "Merger") pursuant to the Agreement and Plan of Merger by and among NetApp, Orca and Merger Sub, dated June 1, 2000 (the "Merger Agreement"). WHEREAS, the provisions of the Merger Agreement require the obligations of Orca under each outstanding option under the Plan to be assumed by NetApp at the consummation of the Merger and the holder of each outstanding option to be issued an agreement evidencing the assumption of such option. WHEREAS, pursuant to the provisions of the Merger Agreement, the exchange ratio (the "Exchange Ratio") in effect for the Merger is 0.139209 of a share of NetApp common stock ("NetApp Stock") for each outstanding share of Orca common stock ("Orca Stock") (rounded down to the nearest whole number of shares of NetApp Stock). WHEREAS, the purpose of this Agreement is to evidence the assumption by NetApp of the outstanding options held by Optionee at the time of the consummation of the Merger (the "Effective Time") and to reflect certain adjustments to those options which have become necessary in connection with their assumption by NetApp in the Merger. NOW, THEREFORE, it is hereby agreed as follows: 1. The number of shares of Orca Stock subject to the options held by Optionee immediately prior to the Effective Time (the "Orca Options") and the exercise price

3 payable per share are set forth below. NetApp hereby assumes, as of the Effective Time, all the duties and obligations of Orca under each of the Orca Options. In connection with such assumption, the number of shares of NetApp Stock purchasable under each Orca Option hereby assumed and the exercise price payable thereunder have been adjusted to reflect the Exchange Ratio. Accordingly, the number of shares of NetApp Stock subject to each Orca Option hereby assumed shall be as specified for that option below, and the adjusted exercise price payable per share of NetApp Stock under the assumed Orca Option shall also be as indicated for that option below. ORCA STOCK OPTIONS NETAPP ASSUMED OPTIONS - ------------------------------------------------- ----------------------------------------------- # of Shares # of Shares of Orca Exercise Price of NetApp Adjusted Exercise Common Stock per Share Common Stock Price per Share - -------------------------- ---------------------- -------------------- -------------------------- $ $ - -------------------------- ---------------------- -------------------- -------------------------- 2. The intent of the foregoing adjustments to each assumed Orca Option is to assure that the spread between the aggregate fair market value of the shares of NetApp Stock purchasable under each such option and the aggregate exercise price as adjusted pursuant to this Agreement will not, immediately after the consummation of the Merger, be greater than the spread which existed, immediately prior to the Merger, between the then aggregate fair market value of the Orca Stock subject to the Orca Option and the aggregate exercise price in effect at such time under the Option Agreement. Such adjustments are also intended to preserve, immediately after the Merger, on a per share basis, the same ratio of exercise price per option share to fair market value per share which existed under the Orca Option immediately prior to the Merger. 3. Each Orca Option shall continue to have a maximum term of ten (10) years from the date of grant, subject to earlier termination (as provided in the applicable Option Agreement) following Optionee's cessation of service or employment. 4. The following provisions shall govern each Orca Option hereby assumed by NetApp: (a) Unless the context otherwise requires, all references in each Option Agreement and the applicable Plan (to the extent incorporated into such Option Agreement) shall be adjusted as follows: (i) all references to the "Company" shall mean NetApp, (ii) all references to "Stock," "Common Stock" or "Shares" shall mean shares of NetApp Stock, (iii) all references to the "Board" shall mean the Board of Directors of NetApp and (iv) all references to the "Committee" shall mean the Compensation Committee of the NetApp Board of Directors. (b) Except as modified by this Agreement, the grant date and the expiration date of each assumed Orca Option and all other provisions which govern either the exercise or the termination of the assumed Orca Option shall remain the same as set forth in the Option Agreement applicable to that option, 2

4 and the provisions of the applicable Plan and the Option Agreement shall accordingly govern and control Optionee's rights under this Agreement to purchase NetApp Stock under the assumed Orca Option. (c) Each Orca Option assumed by NetApp which was originally designated as an Incentive Stock Option under the federal tax laws shall retain such Incentive Stock Option status to the maximum extent allowed by law. (d) Each Orca Option hereby assumed by NetApp shall continue to vest and become exercisable in accordance with the same installment vesting schedule in effect for that option under the applicable Option Agreement immediately prior to the Effective Time; except, that the number of shares subject to each such installment shall be adjusted to reflect the Exchange Ratio. (e) For purposes of applying any and all provisions of the Option Agreement and the applicable Plan relating to Optionee's status as an employee or a consultant of Orca, Optionee shall be deemed to continue in such status as an employee or a consultant for so long as Optionee renders services as an employee or a consultant to NetApp or any present or future majority-owned NetApp subsidiary. Accordingly, the provisions of the Option Agreement governing the termination of the assumed Orca Options upon Optionee's cessation of service as an employee or a consultant of Orca shall hereafter be applied on the basis of Optionee's cessation of employee or consultant status with NetApp and its subsidiaries, and each assumed Orca Option shall accordingly terminate, within the designated time period in effect under the Option Agreement for that option, following such cessation of employee or consultant status. (f) The adjusted exercise price payable for the NetApp Stock subject to each assumed Orca Option shall be payable in any of the forms authorized under the Option Agreement applicable to that option. For purposes of determining the holding period of any shares of NetApp Stock delivered in payment of such adjusted exercise price, the period for which such shares were held as Orca Stock prior to the Merger shall be taken into account. (g) In order to exercise each assumed Orca Option, Optionee must deliver to NetApp a written notice of exercise in which the number of shares of NetApp Stock to be purchased thereunder must be indicated. The exercise notice must be accompanied by payment of the adjusted exercise price payable for the purchased shares of NetApp Stock and should be delivered to NetApp at the following address: Network Appliance, Inc. 495 East Java Drive Sunnyvale, CA 94089 Attention: Janice Mahoney 3

5 5. Except to the extent specifically modified by this Option Assumption Agreement, all of the terms and conditions of each Option Agreement as in effect immediately prior to the Merger shall continue in full force and effect and shall not in any way be amended, revised or otherwise affected by this Stock Option Assumption Agreement. IN WITNESS WHEREOF, Network Appliance, Inc. has caused this Stock Option Assumption Agreement to be executed on its behalf by its duly-authorized officer as of the 14th day of June, 2000.
