TERMS AND CONDITIONS

1.Exercisability of Option.Subject to earlier termination of the Option as provided in this Agreement or the
Plan and changes and adjustments contemplated by the Plan, the Option shall vest and become exercisable in installments of 331/3% of the aggregate number of shares set forth on the
facing page (subject to adjustment) on each of the 1st, 2nd, and 3rd anniversaries of the Grant Date. The Option may be exercised only to the extent the Option is exercisable.



2.Method of Exercise of Option.To the extent exercisable, the Option may be exercised by the delivery to the
Company of a written notice stating the number of shares to be purchased pursuant to the Option and accompanied by payment made in cash or by check payable to the order of the Company in the full
amount of the purchase price of the shares and any amounts required to satisfy applicable withholding taxes. Other payment methods may be permitted only if expressly authorized by the Administrator
with respect to this Option or all options under the Plan, consistent with Section 2.2.2 of the Plan.

3.Continuance of Service as a Non-Employee Director Required.The vesting schedule generally
requires continued service through each applicable vesting date as a condition to the vesting of the applicable installment and rights and benefits under this Agreement. Partial service, even if
substantial, during any vesting period will not entitle the Optionee to any proportionate vesting or avoid or mitigate a termination of rights and benefits upon or following a termination of service,
except as expressly provided in Section 4 below or under the Plan.

4.Effect of Termination of Service as a Non-Employee Director.If the Optionee's service as a
Non-Employee Director of the Company terminates, the Option and all other rights and benefits under this Agreement terminate, except that the vesting of the Option may be accelerated and
the Optionee may at any time within the following applicable period after termination exercise the Option to the extent set forth below, with respect to the applicable reason for the termination of
service.

Subject
to Section 5 below, the terms and conditions of the Plan and changes and adjustments contemplated by the Plan, the vesting of an Option granted less than six months prior
to the applicable termination event (a "Short-Term Option") will not automatically occur but the Board in its sole discretion may accelerate the vesting of up to 20% of the Option as of
the time of the termination event, in which case the Option will become exercisable six months after the Grant Date and the Option will remain exercisable until the expiration of the applicable
exercise period set forth above in this Section 4 as if the Option had been held six months at the time of termination of service.

5.Possible Acceleration and Termination of Awards Upon Change in Control; Adjustments.

Without
limiting the generality of Subsection 5.2 of the Plan or the authority of the Administrator under the Plan, upon the occurrence of (or, as the circumstances may require,
immediately prior to) a Change in Control Event, the Option will become immediately exercisable if it was granted six months or more prior to the date of the Change in Control Event, unless prior to
the Change in Control Event the Board determines that benefits under all Options granted pursuant to the Plan will not accelerate upon
occurrence of the Change in Control Event, or determines that only certain or limited benefits under all Options granted pursuant to the Plan will be accelerated and the extent to which they will be
accelerated, and/or establishes a different time in respect of such Change in Control Event for such acceleration. Any Short-Term Option may, in the discretion of the Board, subject to
earlier termination under other provisions hereof, terminate on such date or continue to vest with continued service and shall become exercisable or alternately, shall be settled in accordance with
the provisions of this Agreement and the Plan.

6.Notices.Any notice to be given under the terms of this Agreement shall be in writing and addressed to the
Company at its principal office, to the attention of the Corporate Secretary and to the Optionee at the address given beneath the Optionee's signature, or at such other address as either party may
hereafter designate in writing to the other.

7.Optionee not a Stockholder.Neither the Optionee nor any other person entitled to exercise the Option shall
have any of the rights or privileges of a stockholder of the Company as to any shares of Common Stock not actually issued and delivered to Optionee prior to delivery of the exercise price and
satisfaction of all other conditions precedent to the due exercise of the Option and delivery of shares.

8.Effect of Award Agreement.This Agreement shall be binding upon and inure to the benefit of any successor or
successors of the Company except to the extent the Committee or the Board determines otherwise, consistent with the terms of the Plan.

9.Choice of Law.The construction, interpretation, performance and enforcement of the Option and this Agreement
shall be governed by the laws of the State of California.

10.Defined Terms.Capitalized terms used and not otherwise defined herein shall have the meaning assigned to
such terms in the Plan.

11.Plan.The Option and all rights of Optionee thereunder are subject to, and the Optionee agrees to be bound
by, all of the terms and conditions of the provisions of the Plan, including but not limited to Section 5.2 (Adjustments; Acceleration) and Section 5.10 (Governing
Law/Construction/Severability). Optionee acknowledges receipt of a copy of the Plan, which is made a part hereof by this reference. Unless otherwise expressly provided in other Sections of this
Agreement, provisions of the Plan that confer discretionary authority on the Committee or the Board do not (and shall not be deemed to) create any additional rights in the Optionee not expressly set
forth above.
