The Shares may be authorized, but unissued, or reacquired Common Stock. If an Option should expire or become unexercisable for any reason without having been exercised in full, the unpurchased Shares which were subject thereto shall, unless the Plan shall have been terminated, become available for future grant under the Plan. -2- 3 4. Administration of and Grants of Options under the Plan. (a) Administrator. Except as otherwise required herein, the Plan shall be administered by the Board. (b) Procedure for Grants. All grants of Options hereunder shall be automatic and non-discretionary and shall be made strictly in accordance with the following provisions: (i) No person shall have any discretion to select which Outside Directors shall be granted Options or to determine the number of Shares to be covered by Options granted to Outside Directors. (ii) Each Outside Director shall be automatically granted an Option to purchase 40,000 Shares upon the date (on or after the effective date of this Plan) on which such person first becomes a Director, whether through election by the stockholders of the Company or appointment by the Board to fill a vacancy; provided, however, that no Option shall be issued under the Plan or become exercisable until stockholder approval of the Plan has been obtained in accordance with Section 16 hereof. (iii) On March 31, 1997 and on each March 31 thereafter during the term of this Plan, each Outside Director shall automatically receive an Option to purchase 15,000 Shares. (iv) The terms of each Option granted hereunder shall be as follows: (A) the term of the Option shall be ten (10) years. (B) the Option shall be exercisable only while the Outside Director remains a Director of the Company, except as set forth in Section 8 hereof. (C) the exercise price per Share shall be 100% of the Fair Market Value per Share on the date of grant of the Option. (D) if granted pursuant to Section 4(b)(ii), the Option shall become exercisable in installments cumulatively as to twenty-five percent (25%) of the Optioned Stock on the first anniversary of the date of grant of the Option and as to six and one-quarter percent (6.25%) of the remaining Optioned Stock for each full calendar quarter thereafter that the Optionee remains a Director. (E) if granted pursuant to Section 4(b)(iii) above, the Option shall become exercisable in installments cumulatively as to twenty-five percent (25%) of the Optioned Stock on the last day of each full calendar quarter after the date of grant, provided that the Optionee remains a Director as of such date. -3- 4 (v) In the event that any Option granted under the Plan would cause the number of Shares subject to outstanding Options plus the number of Shares previously purchased upon exercise of Options to exceed the Pool, then each such automatic grant shall be for that number of Shares determined by dividing the total number of Shares remaining available for grant by the number of Outside Directors on the automatic grant date. No further grants shall be made until such time, if any, as additional Shares become available for grant under the Plan through action of the stockholders to increase the number of Shares which may be issued under the Plan or through cancellation or expiration of Options previously granted hereunder. (c) Powers of the Board. Subject to the provisions and restrictions of the Plan, the Board shall have the authority, in its discretion: (i) to determine, upon review of relevant information and in accordance with Section 2(i) of the Plan, the Fair Market Value of the Common Stock; (ii) to interpret the Plan; (iii) to prescribe, amend and rescind rules and regulations relating to the Plan; (iv) to authorize any person to execute on behalf of the Company any instrument required to effectuate the grant of an Option previously granted hereunder; and (v) to make all other determinations deemed necessary or advisable for the administration of the Plan. (d) Effect of Board's Decision. All decisions, determinations and interpretations of the Board shall be final. (e) Suspension or Termination of Option. If the President of the Company or his designee reasonably believes that an Optionee has committed an act of misconduct, the President may suspend the Optionee's right to exercise any Option pending a determination by the Board (excluding the Outside Director accused of such misconduct). If the Board (excluding the Outside Director accused of such misconduct) determines an Optionee has committed an act of embezzlement, fraud, dishonesty, nonpayment of an obligation owed to the Company, breach of fiduciary duty or deliberate disregard of the Company rules resulting in loss, damage or injury to the Company, or if an Optionee makes an unauthorized disclosure of any Company trade secret or confidential information, engages in any conduct constituting unfair competition, induces any Company customer to breach a contract with the Company or induces any principal for whom the Company acts as agent to terminate such agency relationship, neither the Optionee nor his estate shall be entitled to exercise any Option whatsoever. In making such determination, the Board (excluding the Outside Director accused of such misconduct) shall act fairly and shall give the Optionee an opportunity to appear and present evidence on Optionee's behalf at a hearing before the Board or a committee of the Board. 5. Eligibility. Options may be granted only to Outside Directors. All Options shall be automatically granted in accordance with the terms set forth in Section 4(b) hereof. An Outside Director who has been granted an Option may, if he is otherwise eligible, be granted an additional Option or Options in accordance with such provisions. -4- 5 The Plan shall not confer upon any Optionee any right with respect to continuation of service as a Director or nomination to serve as a Director, nor shall it interfere in any way with any rights which the Director or the Company may have to terminate his directorship at any time. 6. Term of Plan. The Plan shall become effective upon the earlier to occur of its adoption by the Board or its approval by the stockholders of the Company as described in Section 16 of the Plan. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 11 of the Plan. 7. Exercise Price and Consideration. (a) Exercise Price. The per Share exercise price for Optioned Stock shall be 100% of the Fair Market Value per Share on the date of grant of the Option. (b) Form of Consideration. The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Board and may consist entirely of (i) cash, (ii) check, (iii) promissory note, (iv) other shares which (x) in the case of Shares acquired upon exercise of an Option either have been owned by the Optionee for more than six (6) months on the date of surrender or were not acquired, directly or indirectly, from the Company, and (y) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised, (v) delivery of a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company the amount of sale or loan proceeds required to pay the exercise price, (vi) by delivering an irrevocable subscription agreement for the Shares which irrevocably obligates the Optionee to take and pay for the Shares not more than twelve (12) months after the date of delivery of the subscription agreement, (vii) any combination of the foregoing methods of payment, or (viii) such other consideration and method of payment for the issuance of Shares to the extent permitted under applicable law. 8. Exercise of Option. (a) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder shall be exercisable at such times as are set forth in Section 4(b) hereof; provided, however, that no Options shall be exercisable until stockholder approval of the Plan in accordance with Section 16 hereof has been obtained. An Option may not be exercised for a fraction of a Share. An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company. Full payment may consist of any consideration and method of payment allowable under Section 7(b) of the Plan. Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the -5- 6 Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. A share certificate for the number of Shares so acquired shall be issued to the Optionee as soon as practicable after exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 10 of the Plan. Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. (b) Termination of Status as a Director. If an Outside Director ceases to serve as a Director, he may, but only within three (3) months after the date he ceases to be a Director of the Company, exercise his Option to the extent that he was entitled to exercise it at the date of such termination. Notwithstanding the foregoing, in no event may the Option be exercised after its term has expired. To the extent that he was not entitled to exercise an Option at the date of such termination, or if he does not exercise such Option (which he was entitled to exercise) within the time specified herein, the Option shall terminate. (c) Disability of Optionee. Notwithstanding the provisions of Section 8(b) above, in the event an Optionee is unable to continue his service as a Director as a result of his total and permanent disability (as defined in Section 22(e)(3) of the Code), he may, but only within six (6) months from the date of termination, exercise his Option to the extent he was entitled to exercise it at the date of such termination. Notwithstanding the foregoing, in no event may the Option be exercised after its term has expired. To the extent that he was not entitled to exercise the Option at the date of termination, or if he does not exercise such Option (which he was entitled to exercise) within the time specified herein, the Option shall terminate. (d) Death of Optionee. In the event of the death of an Optionee, the Option may be exercised, at any time within six (6) months following the date of death, by the Optionee's estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that had accrued at the date of death. Notwithstanding the foregoing, in no event may the option be exercised after its term has expired. 9. Non-Transferability of Options. Unless determined otherwise by the Board, the Option may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee. If the Administrator makes an Option or Right transferable, such Option or Right shall contain such additional terms and conditions as the Administrator deems appropriate. 10. Adjustments Upon Changes in Capitalization or Merger. -6- 7 (a) Subject to any required action by the stockholders of the Company, the number of Shares covered by each outstanding Option, and the number of Shares which have been authorized for issuance under the Plan but as to which no Options have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option, as well as the price per Share covered by each such outstanding Option, shall be proportionately adjusted for any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the aggregate number of issued Shares effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been "effected without receipt of consideration." Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of Shares of stock of any class, or securities convertible into Shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an Option. In the event of the proposed dissolution or liquidation of the Company, all outstanding Options will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Board. The Board may, in the exercise of its sole discretion in such instances, declare that any Option shall terminate as of a date fixed by the Board and give each Optionee the right to exercise his Option as to all or any part of the Optioned Stock, including Shares as to which the Option would not otherwise be exercisable. (b) In the event of a "Change in Control" of the Company, as defined in paragraph (c) below, any Options outstanding upon the date of such Change in Control that are not yet exercisable and vested on such date shall become one hundred percent (100%) exercisable and vested. (c) Definition of "Change in Control". For purposes of this Section 10, a "Change in Control" means the occurrence of any of the following: (i) When any "person," as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act (other than the Company, a Subsidiary or a Company employee benefit plan, including any trustee of such plan acting as trustee) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing fifty percent (50%) or more of the combined voting power of the Company's then outstanding securities; or (ii) A change in the composition of the Board occurring within a two-year period, as a result of which fewer than a majority of the directors are Incumbent Directors. "Incumbent Directors" shall mean directors who either (A) are directors of the Company as of the date hereof, or (B) are elected, or nominated for election, to the Board with the affirmative votes of at least a majority of the Incumbent Directors at the time of such election or nomination (but shall not include an individual whose election or nomination is in -7- 8 connection with an actual or threatened proxy contest relating to the election of directors to the Company); (iii) The consummation of a merger or consolidation of the Company with any other corporation, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) at least fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; or (iv) The consummation of the sale or disposition by the Company of all or substantially all the Company's assets. (d) Golden Parachute Excise Tax Vesting Acceleration Limitation. Notwithstanding any other provision of this Plan, in the event that the vesting acceleration provided for in this Plan or amounts or benefits otherwise payable to an Optionee (i) constitute "parachute payments" within the meaning of Section 280G of the Code, and (ii) but for this Section 10(d), would be subject to the excise tax imposed by Section 4999 of the Code (the "Excise Tax"), then the Optionee's accelerated vesting hereunder shall be either (i) made in full, or (ii) made as to such lesser extent as would result in no portion of such acceleration, amounts or benefits being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the Excise Tax, results in the receipt by the Optionee on an after-tax basis, of the greatest amount of severance benefits, notwithstanding that all or some portion of such severance benefits may be taxable under Section 4999 of the Code. Unless the Company and the Optionee otherwise agree in writing, any determination required under this Section 10(d) shall be made in writing in good faith by the accounting firm serving as the Company's independent public accountants immediately prior to the Change of Control (the "Accountants"). In the event of a reduction in benefits hereunder, the Optionee shall be given the choice of which benefits to reduce. For purposes of making the calculations required by this Section 10(d), the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and the Optionee shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 10(d). -8- 9 11. Amendment and Termination of the Plan. (a) Amendment and Termination. The Board may at any time amend, alter, suspend, or discontinue the Plan, but no amendment, alteration, suspension, or discontinuation shall be made which would impair the rights of any Optionee under any grant theretofore made, without his or her consent. In addition, to the extent necessary and desirable to comply with any other applicable law or regulation, the Company shall obtain shareholder approval of any Plan amendment in such a manner and to such a degree as required. (b) Effect of Amendment or Termination. Any such amendment or termination of the Plan shall not affect Options already granted and such Options shall remain in full force and effect as if this Plan had not been amended or terminated. 12. Time of Granting Options. The date of grant of an Option shall, for all purposes, be the date determined in accordance with Section 4(b) hereof. Notice of the determination shall be given to each Outside Director to whom an Option is so granted within a reasonable time after the date of such grant. 13. Conditions Upon Issuance of Shares. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, state securities laws, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance. As a condition to the exercise of an Option, the Company may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares, if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned relevant provisions of law. Inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained. 14. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. -9- 10 15. Option Agreement. Options shall be evidenced by written option agreements in such form as the Board shall approve. 16. Stockholder Approval. Continuance of the Plan shall be subject to approval by the stockholders of the Company at or prior to the first annual meeting of stockholders held subsequent to the granting of an Option hereunder. Such stockholder approval shall be obtained in the degree and manner required under applicable state and federal law. -10- 11 ADAPTEC, INC.

As a condition to the exercise of this Option, the Company may require Optionee to make any representation and warranty to the Company as may be required by any applicable law or regulation. 6.

This Option may not be exercised more than ten (10) years from the date of grant of this Option, and may be exercised during such term only in accordance with the Plan and the terms of this Option. 11. Taxation Upon Exercise of Option. Optionee understands that, upon exercise of this Option, he will recognize income for tax purposes in an amount equal to the excess of the then fair market value of the Shares purchased over the exercise price paid for such Shares. (Since the Optionee is subject to Section 16(b) of the Securities Exchange Act of 1934, as amended, the measurement and timing of such income may be deferred, and the Optionee is advised to contact a tax advisor concerning the desirability of filing an 83(b) election in connection with the exercise of the Option.) Upon a resale of such Shares by the Optionee, any difference between the sale price and the fair market value of the Shares on the date of exercise of the Option will be treated as capital gain or loss.
