4. Non-Exclusive Relationship. The Consulting Services being provided by Consultant are on a non-exclusive basis, and Consultant shall be entitled to perform or engage in any activity not inconsistent with or otherwise prohibited by this Agreement or by the surviving provisions of Consultant’s Employment Agreement with the Company, dated as of June 30, 2006, as amended (the “Employment Agreement”).

5. Compensation. The Company shall pay Consultant the following compensation for the Consulting Services provided hereunder:

(a) Hourly Fees. The Company shall pay Consultant at an hourly rate of $605 per hour for Consulting Services actually performed by Consultant (the “Hourly Fee”).

6. Reimbursable Costs. The Company shall reimburse Consultant in accordance with general policies and practices of the Company for actual and reasonable expenses incurred in performing the Consulting Services (“Reimbursable Costs”), payable within 30 days of receipt of an invoice. To the extent that any reimbursements provided to Consultant under this Section 6 are deemed to constitute compensation to Consultant, such amounts shall be paid or reimbursed reasonably promptly, but not later than December 31 of the year following the year in which the expense was incurred. The amount of any reimbursements that constitute compensation in one year shall not affect the amount of reimbursements constituting compensation that are eligible for payment or reimbursement in any other year, and Consultant’s right to such payments or reimbursement of any such expenses shall not be subject to liquidation or exchange for any other benefit.

Consultant agrees to indemnify and hold harmless Company from and against any and all successful claims, demands, actions, settlements (subject to Consultant’s reasonable agreement) or judgments, including reasonable attorney’s fees and litigation expenses, based upon or arising out of the activities described in this Agreement, where such claims, demands, actions, settlements or judgments are caused by (i) the gross negligence or willful misconduct of Consultant or (ii) Consultant’s breach of this Agreement, provided that the liability of Consultant under this Section 13 shall be limited to the amount of the consulting fees earned by Consultant hereunder.

14. Miscellaneous.

(a) Entire Agreement. This Agreement contains the entire understanding and agreement between the Parties relating to the subject matter hereof and supersedes all prior or contemporaneous negotiations, arrangements, agreements, understandings, representations and statements, whether oral or written, with respect to that agreement, all of which are merged herein and shall be of no further force or effect. No Party hereto shall be bound by or liable for any alleged representation, promise, inducement or statement of intention unless set forth herein or in an instrument or other writing delivered hereafter and signed by the Party to be bound thereby. Each of the Parties acknowledges and represents that, except as specifically set forth in this Agreement (or in the Employment Agreement or that certain Separation Agreement, dated as of June 30, 2008, by and between Consultant and the Company) or in an instrument or other writing delivered hereafter and signed by the Party to be bound thereby, such Party has not received any representations, warranties or promises by any person as a means of inducing it to enter into this Agreement, and further acknowledges and represents that it does not enter into this Agreement in reliance upon any oral or written representation, warranty or promise of any person or entity that is not specifically

4

set forth in this Agreement or in such instrument or other writing delivered hereafter and signed by the Party to be bound thereby.

(b) Amendments. No provision of this Agreement may be amended, modified or waived except by a written instrument signed by each of the Parties hereto (or, in the case of a waiver, by the Party against whom enforcement of the waiver is sought).

(c) Parties in Interest. This Agreement shall inure to the benefit of, and shall be binding upon, the Parties hereto and their respective successors and permitted assigns. No transfer of any interest hereunder shall be deemed to release the transferor from any of its obligations hereunder. Nothing in this Agreement is intended to confer any right or remedy under this Agreement on any person other than the Parties to this Agreement and their respective successors and permitted assigns, or to relieve or discharge any obligation or liability of any person to any Party to this Agreement, or to give any person any right of subrogation or action over or against any Party to this Agreement or to any affiliate thereof.

(d) Choice of Law. This Agreement shall be governed by and construed in accordance with the laws of the State of California, without giving effect to the conflict-of-laws rules and principles of said State.

(e) Effect of Waivers and Consents. No waiver of any default or breach by any Party hereto shall be implied from any omission by a Party to take any action on account of such default or breach if such default or breach persists or is repeated and no express waiver shall affect any default or breach other than the default or breach specified in the express waiver, and that only for the time and to the extent therein stated. One or more waivers of any covenant, term or condition of this Agreement by a Party shall not be construed to be a waiver of any subsequent breach of the same covenant, term or condition. The consent or approval by any Party shall not be deemed to waive or render unnecessary the consent to or approval of said Party of any subsequent or similar acts by a Party.

(f) Counterparts. This Agreement, and any document or instrument entered into, given or made pursuant to this Agreement or authorized hereby, and any amendment or supplement hereto or thereto may be executed in two or more counterparts, and by each Party on a separate counterpart, each of which, when executed and delivered, shall be an original and all of which together shall constitute one instrument, with the same force and effect as though all signatures appeared on a single document. Any signature page of this Agreement or of such an amendment, supplement, document or instrument may be detached from any counterpart without impairing the legal effect of any signatures thereon, and may be attached to another counterpart identical in form thereto but having attached to it one or more additional signature pages. In proving this Agreement or any such amendment, supplement, document or instrument, it shall not be necessary to produce or account for more than one counterpart thereof signed by the Party against whom enforcement is sought.

(g) Attorneys’ Fees. If any legal action or any arbitration or other proceeding is brought for the enforcement of this Agreement or any document or instrument entered into, given or made pursuant to this Agreement or authorized hereby or thereby, or because of an alleged dispute, breach, default, or misrepresentation in connection with any of the provisions of this Agreement or of such document or instrument, the successful or prevailing Party shall be entitled to recover the attorneys’ fees, charges and other costs incurred by that Party in and in connection with that action or proceeding, in addition to any other relief to which it may be entitled.
