This letter agreement (the “Agreement”) contains the release referred to in the Employment Agreement and is a condition to the Company’s obligations to pay the severance and benefits set forth in Section 5.4 of the Employment Agreement and described below.

You are entitled to these payments whether or not you sign this Agreement.

     2. Severance Benefits. Subject to your execution of this Agreement and compliance with its terms, in accordance with Section 5.4 of the Employment Agreement, the Company will provide you with the following severance payments and benefits:

          (a) Severance. Subject to the terms of this Section and Section 11 below, the Company will continue to pay you your base salary at the current rate of $375,000 per annum (the “Base Salary”) for the period commencing on the Separation Date and ending on the second anniversary of such date (the “Applicable Period”). Such Base Salary will be paid during the

Applicable Period in equal installments, no less frequently than monthly, pursuant to the Company’s policies in effect at the time of payment. Notwithstanding the foregoing and subject to Section 11, in accordance with Section 5.6 of the Employment Agreement, commencement of these payments shall begin on the first payroll date that occurs in the month that begins at least 60 days after the Separation Date, but which may be accelerated by the Company by no more than 30 days (the “Starting Date”), provided that you have executed and not revoked this Agreement. The first payment on the payment Starting Date shall include those payments that would have previously been paid if these severance payments had begun on the first payroll date following the Separation Date. Such payments will be made in reliance on the short term deferral exemption under Section 409A of the Code (each as defined below in Section 11) until March 15, 2010 and the remaining payments will be delayed as contemplated in Section 11 below.

          (b) COBRA. If you timely elect to continue your health insurance pursuant to COBRA, the Company will pay that portion of the premium that it would have paid if you were an active employee for the same coverage through the earlier of the 18 month period following the Separation Date and your eligibility for comparable coverage with a subsequent employer. You agree to promptly notify the Company in writing in the event that you are offered coverage under another plan.

On the earliest date on which such payments can be commenced without violating the requirements of Section 409A(a)(2)(B)(i) of the Code, you shall be paid, in a single cash lump sum, an amount equal to the aggregate amount of all payments delayed pursuant to the preceding sentence. In addition, any expense reimbursement under this Agreement will be made on or before the last day of the taxable year following the taxable year in which such expense was incurred by you, and no such reimbursement or the amount of expenses eligible for reimbursement in any taxable year will in any way affect the expenses eligible for reimbursement in any other taxable year. The termination of your employment on October 30, 2009 is intended to constitute an “involuntary termination” for purposes of Section 409A. Notwithstanding any of the preceding, the Company makes no representations regarding the tax treatment of any payments hereunder, and you will be responsible for any and all applicable taxes.
