1. Stock Purchase Right. In consideration of the Participant's agreement to remain in the service or
employ of the Company or one of its Subsidiaries, and for other good and valuable consideration which the Administrator has

the restrictions on transfer imposed pursuant to this Agreement, and upon vesting and the satisfaction of all conditions set forth in
Section 2.2(d), the Company shall cause certificates representing the Shares to be issued to the Participant; or (ii) certificate form
pursuant to the terms of Sections 2.1(c) and (d).
3. Legend. Certificates representing Shares issued pursuant to this Agreement shall, until all
restrictions on transfer imposed pursuant to this Agreement lapse or shall have been removed and new certificates are issued, bear the
following legend (or such other legend as shall be determined by the Administrator):
4. Escrow. The Secretary of the Company or such other escrow holder as the Administrator may
appoint may retain physical custody of the certificates representing the Shares until all of the restrictions on transfer imposed pursuant
to this Agreement lapse or shall have been removed; in such event the Participant shall not retain physical custody of any certificates
representing unvested Shares issued to him.

2.2    Restrictions.

ARTICLE III.

OTHER PROVISIONS

3.1    Section 83(b) Election. Participant understands that Section 83(a) of the
Code taxes as ordinary income the difference between the amount, if any, paid for the Shares and the fair market value of such Shares
at the time the Restrictions on such Shares lapse. Participant understands that, notwithstanding the preceding sentence, Participant
may elect to be taxed at the time of the Grant Date, rather that at the time the Restrictions lapse, by filing an election under
Section 83(b) of the Code (an "83(b) Election") with the Internal Revenue Service within 30 days of the Grant
Date. In the event Participant files an 83(b) Election, Participant will recognize ordinary income in an amount equal to the difference
between the amount, if any, paid for the Shares and the fair market value of such Shares as of the Grant Date. Participant further
understands that an additional copy of such 83(b) Election form should be filed with his or her federal income tax return for the calendar
year in which the date of this Agreement falls. Participant acknowledges that the foregoing is only a summary of the effect of United
States federal income taxation with respect to the Shares purchased hereunder, and does not purport to be complete.

Participant further acknowledges that the Company is not responsible for filing the Participant's 83(b)
Election, and the Company has directed Participant to seek independent advice regarding the applicable provisions of the INTERNAL
REVENUE Code, the income tax laws of any municipality, state or foreign country in which Participant may reside, and the tax
consequences of Participant's death.

3.2    Restricted Stock Not Transferable. No Shares or any interest or right therein or part thereof
shall be liable for the debts, contracts or engagements of the Participant or his successors in interest or shall be subject to disposition
by transfer, alienation, anticipation, pledge, encumbrance, assignment or any other means whether such disposition be voluntary or
involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including
bankruptcy), and any attempted disposition thereof shall be null and void and of no effect; provided, however, that this Section
3.2 notwithstanding, with the consent of the Administrator, the Shares may be transferred to certain persons or entities related to
Participant, including but not limited to members of Participant's family, charitable institutions or trusts or other entities whose
beneficiaries or beneficial owners are members of Participant's family or to such other persons or entities as may be expressly
approved by the Administrator, pursuant to any such conditions and procedures the Administrator may require.

3.3    Rights as Stockholder. Except as otherwise provided herein, upon the Grant Date the Participant
shall have all the rights of a stockholder with respect to the Shares, subject to the Restrictions herein, including the right to vote the
Shares and the right to receive any cash or stock dividends paid to or made with respect to the Shares.

3.4    Adjustment for Stock Split. All references to the number of Shares and the purchase price
of the Shares in this Agreement shall be appropriately adjusted to reflect any stock split, stock dividend or other change in the Shares
which may be made by the Company after the date of this Agreement.

A-3



3.5    Not a Contract of Employment. Nothing in this Agreement or in the Plan shall confer upon the
Participant any right to continue to serve as an employee or other service provider of the Company or any of its Subsidiaries.

3.6    Governing Law. The laws of the State of California shall govern the interpretation, validity,
administration, enforcement and performance of the terms of this Agreement regardless of the law that might be applied under
principles of conflicts of laws.

3.7    Conformity to Securities Laws. The Participant acknowledges that the Plan and this Agreement
are intended to conform to the extent necessary with all provisions of the Securities Act of 1933, as amended, and the Exchange Act,
and any and all regulations and rules promulgated thereunder by the Securities and Exchange Commission, including without limitation
Rule 16b-3 under the Exchange Act. Notwithstanding anything herein to the contrary, the Plan shall be administered, and the Shares
are granted, only in such a manner as to conform to such laws, rules and regulations. To the extent permitted by applicable law, the
Plan and this Agreement shall be deemed amended to the extent necessary to conform to such laws, rules and regulations.

3.8    Amendment, Suspension and Termination. To the extent permitted by the Plan, this Agreement
may be wholly or partially amended or otherwise modified, suspended or terminated at any time or from time to time by the
Administrator or the Board, provided, that, except as may otherwise be provided by the Plan, no amendment, modification,
suspension or termination of this Agreement shall adversely effect the Shares in any material way without the prior written consent of
the Participant.

3.9    Notices. Notices required or permitted hereunder shall be given in writing and shall be deemed
effectively given upon personal delivery or upon deposit in the United States mail by certified mail, with postage and fees prepaid,
addressed to the Participant to his address shown in the Company records, and to the Company at its principal executive
office.

3.10    Successors and Assigns. The Company may assign any of its rights under this Agreement to
single or multiple assignees, and this Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding upon Participant and his or her heirs, executors,
