Administration of the Plan. (a) Composition of Administrator. (i) Multiple Administrative Bodies. If permitted by Rule 16b-3 promulgated under the Exchange Act or any successor rule thereto, as in effect at the time that discretion is being exercised with respect to the Plan ("Rule 16b-3"), and by the legal requirements relating to the administration of incentive stock option plans, if any, of applicable securities laws and the Code (collectively, the "Applicable Laws"), the Plan may (but need not) be administered by different administrative bodies with respect to directors, officers who are not directors and Employees who are neither directors nor officers. (ii) Administration with respect to Directors and Officers. With respect to grants of Options to Employees or Consultants who are also officers or directors of the Company, the Plan shall be administered by (A) the Board, if the Board may 3. 4 administer the Plan in compliance with Rule 16b-3 as it applies to a plan intended to qualify thereunder as a discretionary plan, or (B) a Committee designated by the Board to administer the Plan, which Committee shall be constituted (I) in such a manner as to permit the Plan to comply with Rule 16b-3 as it applies to a plan intended to qualify thereunder as a discretionary plan and (II) in such a manner as to satisfy the Applicable Laws. (iii) Administration with respect to Other Persons. With respect to grants of Options to Employees or Consultants who are neither directors nor officers of the Company, the Plan shall be administered by (A) the Board or (B) a Committee designated by the Board, which Committee shall be constituted in such a manner as to satisfy the Applicable Laws. (iv) General. Once a Committee has been appointed pursuant to subsection (ii) or (iii) of this Section 4(a), such Committee shall continue to serve in its designated capacity until otherwise directed by the Board. From time to time the Board may increase the size of any Committee and appoint additional members thereof, remove members (with or without cause) and appoint new members in substitution therefor, fill vacancies (however caused) and remove all members of a Committee and thereafter directly administer the Plan, all to the extent permitted by the Applicable Laws and, in the case of a Committee appointed under subsection (ii), to the extent permitted by Rule 16b-3 as it applies to a plan intended to qualify thereunder as a discretionary plan. (b) Powers of the Administrator. Subject to the provisions of the Plan and in the case of a Committee, the specific duties delegated by the Board to such Committee, the Administrator shall have the authority, in its discretion: (i) to determine the Fair Market Value of the Common Stock, in accordance with Section 2(l) of the Plan; (ii) to select the officers, Consultants and Employees to whom Options may from time to time be granted hereunder; (iii) to determine whether and to what extent Options are granted hereunder; (iv) to determine the number of shares of Common Stock to be covered by each such award granted hereunder; (v) to approve forms of agreement for use under the Plan; (vi) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any award granted hereunder (including, but not limited to, the share price and any restriction or limitation, or any vesting acceleration or waiver of forfeiture restrictions regarding any Option and/or the shares of Common Stock relating thereto, based 4. 5 in each case on such factors as the Administrator shall determine, in its sole discretion); (vii) to determine whether, to what extent and under what circumstances Common Stock and other amounts payable with respect to an award under this Plan shall be deferred either automatically or at the election of the participant (including providing for and determining the amount, if any, of any deemed earnings on any deferred amount during any deferral period); and (viii) to reduce the exercise price of any Option to the then current Fair Market Value if the Fair Market Value of the Common Stock covered by such Option shall have declined since the date the Option was granted. (c) Effect of Administrator's Decision. All decisions, determinations and interpretations of the Administrator shall be final and binding on all Optionees and any other holders of any Options. 5. Eligibility. (a) Options may be granted only to Employees and Consultants. Incentive Stock Options may be granted only to Employees. An Employee or Consultant who has been granted an Option may, if he or she is otherwise eligible, be granted an additional Option or Options. (b) Each Option shall be designated in the written option agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designations, to the extent that the aggregate Fair Market Value of Stock Options are exercisable for the first time by an Optionee during any calendar year (under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. (c) For purposes of Section 5(b), Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares shall be determined as of the time the Option with respect to such Shares is granted. (d) The Plan shall not confer upon any Optionee any right with respect to continuation of employment or consulting relationship with the Company, nor shall it interfere in any way with his or her right or the Company's right to terminate his or her employment or consulting relationship at any time, with or without cause. 6. Term of Plan. The Plan shall become effective upon the earlier to occur of its adoption by the Board of Directors or its approval by the stockholders of the Company as described in Section 18 below. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 13 below. 5. 6 7. Term of Option. The term of each Incentive Stock Option shall be ten (10) years from the date of grant thereof or such shorter term as may be provided in the Stock Option Agreement. The term of each Option that is not an Incentive Stock Option shall be ten (10) years and one (1) day from the date of grant thereof or such shorter term as may be provided in the Stock Option Agreement. However, in the case of an Option granted to an Optionee who, at the time the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, (a) if the Option is an Incentive Stock Option, the term of the Option shall be five (5) years from the date of grant thereof or such shorter time as may be provided in the Stock Option Agreement, or (b) if the Option is not an Incentive Stock Option, the term of the Option shall be five (5) years and one (1) day from the date of grant thereof or such shorter term as may be provided in the Stock Option Agreement. 8. Exercise Price and Consideration. (a) The per Share exercise price for the Shares to be issued pursuant to exercise of an Option shall be such price as is determined by the Administrator, but shall be subject to the following: (i) In the case of an Incentive Stock Option (A) granted to an Employee who, at the time of the grant of such Incentive Stock Option, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be no less than one hundred ten percent (110%) of the Fair Market Value per Share on the date of grant. (B) granted to any other Employee, the per Share exercise price shall be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. (ii) In the case of any Option, the per Share exercise price shall be no less than eighty-five percent (85%) of the Fair Market Value per Share on the date of grant. (b) The Administrator shall determine the acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator shall determine the acceptable form of consideration at the time of grant. Such consideration may consist entirely of: (i) cash; (ii) check; 6. 7 (iii) promissory note; (iv) other Shares which (A) in the case of Shares acquired upon exercise of an option, have been owned by the Optionee for more than six months on the date of surrender, and (B) 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 such other documentation as the Administrator and the broker, if applicable, shall require to effect an exercise of the Option and delivery to the Company of the sale or loan proceeds required to pay the exercise price; (vi) any combination of the foregoing methods of payment; or (vii) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Law. 9. Exercise of Option (a) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder shall be exercisable at such times and under such conditions as determined by the Administrator, including performance criteria with respect to the Company and/or the Optionee, and shall be permissible under the terms of the Plan; provided, however, than an Incentive Stock Option granted prior to January 1, 1987 shall not be exercisable while there is outstanding any incentive stock option which was granted, before the granting of such Incentive Stock Option, to the same Optionee to purchase stock of the Company, any Parent or Subsidiary, or any predecessor corporation of such corporations. For purposes of this provision, an incentive stock option shall be treated as outstanding until such option is exercised in full or expires by reason of lapse of time. 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, as authorized by the Administrator, consist of any consideration and method of payment allowable under Section 8(b) above. Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the stock certificates 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. No adjustment shall 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 11 below. 7. 8 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 an Employee or Consultant. If an Employee or Consultant ceases to serve as an Employee or Consultant, then he or she may, but only within thirty (30) days (or such other period of time not exceeding three (3) months as is determined by the Administrator, with such determination in the case of an Incentive Stock Option being made at the time of the grant of the Option) after the date he or she ceases to be an Employee or Consultant of the Company (but in no event later than the date of expiration of the term of such Option as set forth in the Option Agreement, exercise his or her Option to the extent that he or she was entitled to exercise it at the date of such termination. To the extent that he or she was not entitled to exercise the Option at the date of such termination, or if he or she does not exercise such Option (which he or she was entitled to exercise) within the time specified herein, the Option shall terminate. (c) Disability of Optionee. Notwithstanding the provisions of Section 9(b) above, if an Employee or Consultant is unable to continue his or her employment or consulting relationship with the Company as a result of his or her total and permanent disability (as defined in Section 22(e)(3) of the Code), then he or she may, but only within six (6) months (or such other period of time not exceeding twelve (12) months as is determined by the Administrator, with such determination in the case of an Incentive Stock Option being made at the time of the grant of the Option) from the date of termination (but in no event later than the date of expiration of the term of such Option as set forth in the Option Agreement), exercise his or her Option to the extent he or she was entitled to exercise it at the date of termination of employment or consulting. To the extent that he or she was not entitled to exercise the Option at the date of termination, or if he or she does not exercise such Option (which he or she 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: (i) during the term of the Option who is at the time of his or her death an Employee or Consultant of the Company and who shall have been in Continuous Status as an Employee or Consultant since the date of grant of the Option, the Option may be exercised, at any time within three (3) months following the date of death (but in no event later than the date of expiration of the term of such Option as set forth in the Option Agreement), 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 would have accrued had the Optionee continued living and remained in Continuous Status as an Employee or Consultant three (3) months after the date of death; or (ii) within one (1) month (or such other period of time not exceeding three (3) months as is determined by the Administrator, with such determination in 8. 9 the case of an Incentive Stock Option being made at the time of grant of the Option) after the termination of Continuous Status as an Employee or Consultant, the Option may be exercised, at any time within three (3) months following the date of death (but in no event later than the date of expiration of the term of such Option as set forth in the Option Agreement), 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 termination. (e) Rule 16b-3. Options granted to persons subject to Section 16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions. 10. Non-Transferability of Options. 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. The designation of a beneficiary by an Optionee does not constitute a transfer. An Option may be exercised, during the lifetime of the Optionee, only by the Optionee. 11. Adjustments Upon Changes in Capitalization or Merger. Subject to any required action by the stockholders of the Company, the number of shares of Common Stock covered by each outstanding Option, and the number of shares of Common Stock 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 of Common Stock covered by each such outstanding Option, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock 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 number of issued shares of Common Stock 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 Administrator, 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 of Common Stock subject to an Option. In the event of the proposed dissolution or liquidation of the Company, the Administrator shall notify the Optionee at least fifteen (15) days prior to such proposed action. To the extent it has not been previously exercised, the Option shall terminate immediately prior to the consummation of such proposed action. In the event of a merger of the Company with or into another corporation, the Option shall be assumed or an equivalent option shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation, unless the Administrator determines, in the exercise of its sole 9. 10 discretion and in lieu of such assumption or substitution, that the Optionee shall have the right to exercise the Option as to all of the Optioned Stock, including Shares as to which the Option would not otherwise be exercisable. If the Administrator makes an Option fully exercisable in lieu of assumption or substitution in the event of a merger, then the Administrator shall notify the Optionee that the Option shall be fully exercisable for a period of thirty (30) days from the date of such notice, and the Option shall terminate upon the expiration of such period. 12. Time of Granting Options. The date of grant of an Option shall, for all purposes, be the date on which the Administrator makes the determination granting such Option or such other date as is determined by the Administrator. Notice of the determination shall be given to each Employee or Consultant to whom an Option is so granted within a reasonable time after the date of such grant. 13. Amendment and Termination of the Plan. (a) Amendment and Termination. The Board may amend or terminate the Plan from time to time in such respects as the Board may deem advisable; provided, however, that the following revisions or amendments shall require approval of the stockholders of the Company in the manner described in Section 18 of the Plan: (i) any increase in the number of Shares subject to the Plan, other than in connection with an adjustment under Section 11 above; (ii) any change in the designation of the class of persons eligible to be granted Options; or (iii) if the Company has a class of equity security registered under Section 12 of the Exchange Act at the time of such revision or amendment, any material increase in the benefits accruing to participants under the Plan. (b) Stockholder Approval. If any amendment requiring stockholder approval under Section 13(a) above is made subsequent to the first registration of any class of equity security by the Company under Section 12 of the Exchange Act, then such stockholder approval shall be solicited as described in Section 18 below. (c) 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, unless mutually agreed otherwise between the Optionee and the Board, which agreement must be in writing and signed by the Optionee and the Company. 14. 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 10. 11 delivery of such Shares pursuant thereto complies 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, and the requirements of any stock exchange upon which the Shares may then be listed. The exercise of such Option and the issuance and delivery of such Shares pursuant thereto 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. 15. 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. 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. 16. Option Agreement. Options shall be evidenced by written option agreements in such form as the Administrator shall approve. 17. Annual Report to Optionees. The Board of Directors shall cause an annual report to be sent to the Optionees not later than one hundred twenty (120) days after the close of the fiscal year adopted by the corporation. Such report shall be sent at least fifteen (15) days (or, if sent by third-class mail, thirty-five (35) days) before the annual meeting of stockholders to be held during the next fiscal year. The annual report shall contain (i) a balance sheet as of the end of the fiscal year, (ii) an income statement, (iii) a statement of changes in financial position for the fiscal year, and (iv) any report of independent accountants or, if there is not such report, the certificate of an authorized officer of the corporation that the statements were prepared without audit from the books and records of the corporation. 18. Stockholder Approval. (a) Continuance of the Plan shall be subject to approval by the stockholders of the Company within twelve (12) months before or after the date of the Plan is adopted. (b) If and in the event that the Company registers any class of 11. 12 equity securities pursuant to Section 12 of the Exchange Act, any required approval of the stockholders of the Company obtained after such registration shall be solicited substantially in accordance with Section 14(a) of the Exchange Act and the rules and regulations promulgated thereunder. (c) If any required approval by the stockholders of the Plan itself or of any amendment thereto is solicited at any time otherwise than in the manner described in Section 18(b) hereof, then the Company shall, at or prior to the first annual meeting of stockholders held subsequent to the later of (1) the first registration of any class of equity securities of the Company under Section 12 of the Exchange Act or (2) the granting of an Option hereunder to an officer or director after such registration, do the following: (i) furnish in writing to the holders entitled to vote for the Plan substantially the same information which would be required (if proxies to be voted with respect to approval or disapproval of the Plan or amendment were then being solicited) by the rules and regulations in effect under Section 14(a) of the Exchange Act at the time such information is furnished; and (ii) file with, or mail for filing to, the Securities and Exchange Commission four copies of the written information referred to in subsection (i) hereof not later than the date on which such information is first sent or given to stockholders. 12.
