provided, however, that a transaction shall not constitute a Change in Control if its sole purpose is to change the state of the Company’s incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who directly or indirectly held the Company’s securities immediately before such transaction.

(iii) “Good Reason” means:

(A) a reduction of Employee’s then existing annual base salary by more than 10% (other than in collection with an action affecting a majority of the executive officers of the Company);

Section 2.03. Accrued Compensation and Benefits. In connection with any termination of employment upon or following a Change in Control (whether or not under Section 2.01 above), the Company shall pay Employee’s earned but unpaid base salary and other vested but unpaid cash entitlements for the period through and including the termination of employment, including unused earned vacation pay and unreimbursed documented business expenses incurred by Employee prior to the date of termination (collectively “Accrued Compensation and Expenses”), as required by law and the applicable Company plan or policy. In addition, Employee shall be entitled to any other vested benefits earned by Employee for the period through and including the termination date of Employee’s employment under any other employee benefit plans and arrangements maintained by the Company, in accordance with the terms of such plans and arrangements, except as modified herein (collectively “Accrued Benefits”).

Section 2.05. Limitation on Payments.

(a) If the Change in Control Severance Benefits together with any other payment or benefit Employee would receive pursuant to a Change in Control (collectively, “Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the Reduced Amount. The “Reduced Amount” shall be either (x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount, after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in Employee’s receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment maybe subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment equals the Reduced Amount, reduction shall occur in the following order unless

4

Employee elects in writing a different order: reduction of cash payments; cancellation of acceleration of vesting; reduction of employee benefits. In the event that acceleration of vesting is to be reduced, it shall be cancelled in the reverse order of the date of grant of the Equity Awards unless Employee elects in writing a different order for cancellation.

(b) The Company may engage the accounting firm engaged by the Company for general audit purposes as of the day prior to the effective date of the Change in Control or another firm to perform the foregoing calculations. The Company shall bear all expenses with respect to the determinations by such firm required to be made hereunder.

(c) The accounting firm engaged to make the determinations hereunder shall provide its calculations, together with detailed supporting documentation, to Employee and the Company within fifteen (15) calendar days after the date on which Employee’s right to a Payment is triggered (if requested at that time by Employee or the Company) or such other time as requested by Employee or the Company.

ARTICLE 3

MISCELLANEOUS

Section 3.01. Assignment; Successors and Assigns. This Agreement shall inure to the benefit of and be enforceable by Employee’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees, and legatees. If Employee should die or become subject to a permanent disability while any amount is owed but unpaid to Employee hereunder, all such amounts, unless otherwise provided herein, shall be paid to Employee’s devisee, legatee, legal guardian or other designee, or if there is no such designee, to Employee’s estate. Employee’s rights hereunder shall not otherwise be assignable. This Agreement shall be binding on the Company’s successors and assigns.

Section 3.02. Dispute Resolution. To ensure rapid and economical resolution of any and all disputes that might arise in connection with this Agreement, Employee and the Company agree that any and all disputes, claims, and causes of action, in law or equity, arising from or relating to this Agreement or its enforcement, performance, breach, or interpretation, will be resolved solely and exclusively by final, binding, and confidential arbitration, by a single arbitrator, in San Francisco, California, and conducted by Judicial Arbitration & Mediation Services, Inc. (“JAMS”) under its then existing employment rules and procedures. Nothing in this section, however, is intended to prevent either party from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration. Each party to an arbitration or litigation hereunder shall be responsible for the payment of its own attorneys’ fees.

Section 3.03. Unfunded Agreement. The obligations of the Company under this Agreement represent an unsecured, unfunded promise to pay benefits to Employee and/or Employee’s beneficiaries, and shall not entitle Employee or such beneficiaries to a preferential claim to any asset of the Company.

5

Section 3.04. Non-exclusivity of Benefits. Unless specifically provided herein, neither the provisions of this Agreement nor the benefits provided hereunder shall reduce any amounts otherwise payable, or in any way diminish Employee’s rights as an employee of the Company, whether existing now or hereafter, under any compensation and/or benefit plans (qualified or nonqualified), programs, policies, or practices provided by the Company, for which Employee may qualify; provided that the Change in Control Severance Benefits shall not be duplicative of any severance benefits under any such plans, programs, policies or practices. Vested benefits or other amounts which Employee is otherwise entitled to receive under any plan, policy, practice, or program of the Company (i.e., including, but not limited to, vested benefits under any qualified or nonqualified retirement plan), at or subsequent to the termination date shall be payable in accordance with such plan., policy, practice, or program except as expressly modified by this Agreement.

Section 3.05. Mitigation. In no event shall Employee be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to Employee under any of the provisions of this Agreement nor shall the amount of any payment or benefit hereunder be reduced by any compensation earned by Employee as a result of employment by another employer.

Section 3.06. Entire Agreement. This Agreement represents the entire agreement between Employee and the Company and its affiliates with respect to Employee’s severance rights in a Change in Control situation, and supersedes all prior and contemporaneous discussions, negotiations, and agreements concerning such rights, provided, however, that any amounts payable to Employee hereunder shall be reduced by any amounts paid to Employee as required by any applicable federal, state or local law (including without limitation the WARN Act) in connection with any termination of Employee’s employment.

Section 3.07. Tax Withholding. Notwithstanding anything in this Agreement to the contrary, the Company shall withhold from any amounts payable under this Agreement all federal, state, city, or other taxes as are legally required to be withheld.

Section 3.08. Waiver of Rights. The waiver by either party of a breach of any provision of this Agreement shall not operate or be construed as a continuing waiver or as a consent to or waiver of any subsequent breach hereof.

Section 3.09. Severability. In the event any provision of the Agreement shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Agreement, and the Agreement shall be construed and enforced as if the illegal or invalid provision had not been included.

6

Section 3.10. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of California without reference to principles of conflict of laws.

Section 3.11. Counterparts. This Agreement may be signed in several counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were on the same instrument.

Section 3.12. Code Section 409A. This Agreement and the payments and benefits hereunder are intended to qualify for the short-term deferral exception to Section 409A of the Code, and all regulations, rulings and other guidance issued thereunder, all as amended and in effect from time to time (“Section 409A”), described in Treasury Regulation Section 1.409A-l(b)(4) to the maximum extent possible, and to the extent they do not so qualify, they are intended to qualify for the involuntary separation pay plan exception to Section 409A described in Treasury Regulation Section 1.409A-l(b)(9)(iii) to the maximum extent possible. To the extent Section 409A is applicable to this Agreement, this Agreement is intended to comply with Section 409A. Without limiting the generality of the foregoing, if on the date of termination of employment Employee is a “specified employee” within the meaning of Section 409A as determined in accordance with the Company’s procedures for making such determination, to the extent required in order to comply with Section 409A, amounts that would otherwise be payable under this Agreement during the six-month period immediately following the termination date shall instead be paid on the first business day after the date that is six months following the termination date. All references herein to “termination date” or “termination of employment” shall mean separation from service as an employee within the meaning of Section 409A.

IN WITNESS WHEREOF, the Company and the Employee have executed this Agreement, to be effective as of the date and year first written above.

This Release does not apply to (x) claims which cannot be released as a matter of law, (y) any right I may have to enforce the Agreement or (z) my eligibility for indemnification in accordance with applicable laws, the charter and bylaws of the Company or any indemnification agreement I have with the company.

2. ADEA Waiver. I acknowledge that I am knowingly and voluntarily waiving and releasing any rights you have under the ADEA and that the consideration given for the waiver and release is in addition to anything of value to which I was already entitled.

3. Waiver of Unknown Claims. In granting the general release herein, I acknowledge that I have read and understand California Civil Code section 1542, which states:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

I expressly waive and relinquish all rights and benefits under that section and any law of any jurisdiction of similar effect.

This Release, together with the Agreement, constitutes the entire understanding of the parties on the subjects covered.
