Unless earlier terminated, this option shall expire ten years from the Grant Date (the "Final Exercise Date"). It is intended that the option evidenced by this agreement shall be an incentive stock option as defined in Section 422 of the Internal Revenue Code of 1986, as amended and any regulations promulgated thereunder (the "Code"). Except as otherwise indicated by the context, the term "Participant", as used in this option, shall be deemed to include any person who acquires the right to exercise this option validly under its terms. 2. Vesting Schedule. ---------------- The date to be used for determining vesting of this option ("Vesting Effective Date") shall be HIRE DATE. This option will become exercisable ("vest") as to 20% of the original number of Shares on the first anniversary of the Vesting Effective Date and as to an additional 5% of the original number of Shares at the end of each successive full three-month period following the first anniversary of the Vesting Effective Date until the fifth anniversary of the Vesting Effective Date. This option shall expire upon, and will not be exercisable after, the Final Exercise Date. The right of exercise shall be cumulative so that to the extent the option is not exercised in any period to the maximum extent permissible it shall continue to be exercisable, in whole or in part, with respect to all shares for which it is vested until the earlier of the Final Exercise Date or the termination of this option under Section 3 hereof or the Plan. Notwithstanding the foregoing, in the event of an Acquisition of the Company (as defined below), the number of Shares for which the option is vested shall, immediately prior to the Closing of the Acquisition, be increased by (i) 20% of the original number of Shares covered by this option, if the Participant has been employed by the Company for 12 or more months prior to the Acquisition, or (ii) 10% of the original number of Shares covered by this option, if the Participant has been employed by the Company for less than 12 months prior to the Acquisition. The remaining unvested shares shall vest in accordance with their original vesting schedule, except that such schedule shall be shortened by 12 months (in the case of an acceleration under clause (i) above) or six months (in the case of an acceleration under clause (ii) above). "Acquisition" shall mean (i) the consolidation or merger of the Company (other than a merger to reincorporate the Corporation in a different jurisdiction) into or with any other entity or entities in which the shares of the Corporation outstanding immediately prior to the closing of such event represent or are converted into shares of the surviving or resulting entity that represent less than a majority of the total number of shares of the surviving or resulting entity that are outstanding or are reserved for issuance upon the exercise or conversion of outstanding securities immediately after the closing of such event, or (ii) the sale or transfer of fifty percent (50%) or more of the capital stock of the Corporation in a single transaction or series of related transactions or (iii) the sale of all or substantially all of the assets of the Company. 3. Exercise of Option. ------------------ (a) Form of Exercise. Each election to exercise this option shall be in ---------------- writing, signed by the Participant, and received by the Company at its principal office, accompanied by this agreement, and payment in full in the manner provided in the Plan.

(b) Continuous Relationship with the Company Required. Except as otherwise ------------------------------------------------- provided in this Section 3, this option may not be exercised unless the Participant, at the time he or she 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 or any parent or subsidiary of the Company as defined in Section 424(e) or (1) of the Code (an "Eligible Participant"). (c) Termination of Relationship with the Company. If the Participant -------------------------------------------- ceases to be an Eligible Participant for any reason, then, except as provided in paragraphs (d) and (e) below, the right to exercise this option shall terminate three months after such cessation (but in no event after the Final Exercise Date), provided that this option shall -------- ---- be exercisable only to the extent that the Participant was entitled to exercise this option on the date of such cessation. Notwithstanding the foregoing, if the Participant, prior to the Final Exercise Date, violates the non-competition or confidentiality provisions of any employment contract, confidentiality and nondisclosure agreement or other agreement between the Participant and the Company, the right to exercise this option shall terminate immediately upon written notice to the Participant from the Company describing such violation. (d) Exercise Period Upon Death or Disability. If the Participant dies or ---------------------------------------- becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior to the Final Exercise Date while he or she is an Eligible Participant and the Company has not terminated such relationship for "cause" as specified in paragraph (e) below, this option shall be exercisable, within the period of one year following the date of death or disability of the Participant by the Participant, provided that -------- ---- this option shall be exercisable only to the extent that this option was exercisable by the Participant on the date of his or her death or disability, and further provided that this option shall not be exercisable after the Final Exercise Date.

(d) If the Company does not elect to acquire all of the Offered Shares, the Participant may, within the 30-day period following the expiration of the option granted to the Company under subsection (b) above, transfer the Offered Shares to the proposed transferee, provided that -------- ---- such transfer shall not be on terms and conditions more favorable to the transferee than those contained in the Transfer Notice. Notwithstanding any of the above, all Offered Shares transferred pursuant to this Section 4 shall remain subject to the right of first refusal set forth in this Section 4 and such transferee shall, as a condition to such transfer, deliver to the Company a written instrument confirming that such transferee shall be bound by all of the terms and conditions of this Section 4.

(h) The Company shall not be required (a) to transfer on its books any of the Shares which shall have been sold or transferred in violation of any of the provisions set forth in this Section 4, or (b) to treat as owner of such Shares or to pay dividends to any transferee to whom any such Shares shall have been so sold or transferred. 5. Agreement in Connection with Public Offering. -------------------------------------------- The Participant agrees, in connection with the initial underwritten public offering of the Company's securities pursuant to a registration statement under the Securities Act, (i) not to sell, make short sale of, loan, grant any options for the purchase of, or otherwise dispose of any shares of Common Stock held by the Participant (other than those shares included in the offering) without the prior written consent of the Company or the underwriters managing such initial underwritten public offering of the Company's securities for a period of 180 days from the effective date of such registration statement, and (ii) to execute any agreement reflecting clause (i) above as may be requested by the Company or the managing underwriters at the time of such offering. 6.
