11. Consent to Arbitration. Except as prohibited by law, the Company and you agree that any claim, controversy or legal dispute between you and the Company and/or any officer, director, shareholder, agent or employee of the Company, each of whom is hereby designated a third party beneficiary of this agreement regarding arbitration, (a “Dispute”) arising out of your employment or termination of such employment or this letter will be resolved through binding arbitration in San Francisco County, under the Arbitration Rules set forth in California Code of Civil Procedure Section 1280 et seq., and pursuant to California law. This includes any claims you may make relating to alleged discrimination or harassment during employment based on race, color, national origin, religion, disability, age, gender or sexual orientation, any claims relating to compensation (wages, bonuses, benefits, etc.) and any claims under federal state, or local laws or regulations relating to terms and conditions of employment. THE COMPANY AND YOU UNDERSTAND THAT BY AGREEING TO ARBITRATE DISPUTES EACH IS WAIVING ANY RIGHT TO A JURY TRIAL. This arbitration provision is not intended to modify or limit the remedies available to either party, including the right to seek interim relief, such as injunction or attachment, through judicial process, which will not be deemed a waiver of the right to demand and obtain arbitration. Any Dispute that is not arbitrated, including any judicial action to enforce this arbitration provision will be litigated exclusively in federal or California courts located in San Francisco County, California, and the parties hereby consent and submit to the jurisdiction and venue of such courts.

12. Proof of Right to Work. For purposes of federal immigration law, you will be required to provide to the Company documentary evidence of your identity and eligibility for employment in the United States. Such documentation must be provided to us within three (3) business days of your date of hire, or our employment relationship with you may be terminated.

13. Status. You understand that your employment will be voluntary and at-will. You are free to resign at any time, just as the Company is free to terminate your employment at any time. No one can change the at-will status of your employment except the CEO, and such a change is only valid if it is made expressly in writing and approved by the required vote of the Board of Directors.

14. Governing Law. This letter and the terms of your employment shall be governed by the laws of the state of California, without reference to its conflicts of law principles.

15. Internal Revenue Code Section 409A.

(a) To the fullest extent applicable, amounts and other benefits payable under this letter agreement are intended to be exempt from the definition of “nonqualified deferred compensation” under Section 409A of the Internal Revenue Code. In this regard, each payment under this letter agreement that is made in a series of scheduled installments, including each salary continuation payment under section 9(a), shall be deemed a separate payment for purposes of Section 409A.

(b) To the extent that any amounts or benefits payable under this letter agreement are or become subject to Section 409A due to a failure to qualify for an exemption from the definition of nonqualified deferred compensation, this letter agreement is intended to comply with the applicable requirements of Section 409A with respect to such amounts or benefits. This letter agreement shall be interpreted and administered to the extent possible in a manner consistent with the foregoing statement of intent.

(c) In each case where this letter agreement provides for the payment of an amount that constitutes nonqualified deferred compensation under Section 409A to be made to you within a designated period and such period begins and ends in different calendar years, the exact payment date within such range shall be determined by the Company, in its sole discretion, and you shall have no right to designate the year in which the payment shall be made.

(d) Notwithstanding anything in this letter agreement or elsewhere to the contrary, if the Company is a public company on your date of termination and you are a “Specified Employee” within the meaning of Section 409A (as determined by the Company’s Board of Directors) on such date, and the Company reasonably determines that any amount or other benefit payable under this letter agreement on account of your separation from service constitutes nonqualified deferred compensation subject to Section 409A, then the payment thereof shall be postponed and then paid in a single lump sum on the first business day of the seventh month following the date of termination or, if earlier, the date of your death to the extent necessary to comply with Section 409A. The Company and you may agree to take other actions to avoid the application of, or to comply with, Section 409A at such time and in such manner as permitted under Section 409A.

(e) Your date of termination for purposes of determining the date that any payment or benefit that is treated as nonqualified deferred compensation under Section 409A is to be paid or

provided (or in determining whether an exemption to such treatment applies), and for purposes of determining whether you are a “Specified Employee” on the date of termination, shall be the date on which you have incurred a “separation from service” within the meaning of Section 409A and applicable guidance thereunder.

We are very pleased to make this offer to you and look forward to a successful relationship. Please sign the enclosed copy of this letter, as provided below, and return it to me within ten (10) days from the date of this letter. If there are any aspects of this offer which you would like clarified, please let me know.

EXHIBIT A

DEFINITIONS

“Cause” shall mean (A) gross negligence or willful misconduct in the performance of your duties to the Company where such gross negligence or willful misconduct has resulted or is likely to result in substantial damage to the Company or its subsidiaries; (B) commission of any act of fraud or dishonesty with respect to the Company or breach of your fiduciary duties to the Company; (C) conviction of a felony or a crime involving moral turpitude or otherwise causing material harm to the standing and reputation of the Company; (D) any failure to substantially perform your material duties as an employee of the Company, which failure is not cured within thirty (30) days after written notice from the Board of Directors specifying the act(s) of nonperformance; or (E) a material breach of your obligations under the terms of this letter agreement or under any agreement between you and the Company that is not caused by your medical condition, which, if such breach can be cured, is not cured within thirty (30) days after receipt of a written notice of such breach.

“Good Reason” shall mean (i) a reduction of more than 10% of your Base Salary, except that neither a reduction proportionate to reductions imposed on all other members of the Company’s executive management as part of a cost reduction effort nor a reduction of your Base Salary due to a change of duties as a result of disability will be a Good Reason for termination; (ii) a material diminution in your authorities, duties or responsibilities; or (iii) a change of more than 50 miles in the geographic location at which you must perform your duties and responsibilities under this letter agreement. If you intend to resign for one of the Good Reasons listed above, you shall give notice of such intent to the Company within 15 days after the occurrence of the circumstances giving rise to the Good Reason, detailing such Good Reason with specificity. If the Company does not remedy the situation so as to eliminate the Good Reason within 30 days of receiving such notice, then any resignation by you from the Company within the two (2) month period beginning with the delivery of the notice shall be deemed a termination of your employment for “Good Reason.”
