You acknowledge that your employment as Global Executive Vice President, Technology, Operations and Panel, and Chief Information Officer of the Company will terminate by mutual agreement, effective June 24, 2011 (hereinafter, the “Separation Date”). You agree that as of the Separation Date, you will not represent yourself to be associated in any capacity with the Company or the Releasees (as defined below). Additionally, beginning on the date hereof and continuing for a period of ninety (90) days following the Separation Date, you agree to assist and cooperate with the Company in transitioning your duties and responsibilities to the appropriate individual(s) within the Company by meeting with such individual(s) as reasonably requested from time to time and responding to requests for information. Pre-approved expenses incurred in connection with such assistance and cooperation shall be reimbursed by the Company.

2. Compensation. Regardless of whether you sign this Agreement and Release, your total and final compensation, payments and benefits from the Company shall be as follows (subject to applicable deductions and withholdings):

a. You will be paid your accrued and unpaid base compensation through the Separation Date.

b. Your medical insurance benefits will remain in effect through the Separation Date. Thereafter, you will be eligible to participate in COBRA for medical insurance for a period of up to eighteen (18) months, provided that you remain eligible for such coverage pursuant to COBRA. You will be provided with documentation necessary in order to apply for such continued COBRA coverage. You will be responsible for all COBRA premium payments, except as otherwise stated herein.

c. Upon the Separation Date, you will cease to actively participate in all other benefit plans and programs, including, but not limited to, the Company’s 401(k) plan and any entitlements thereunder will be governed by the terms of such plans and programs. You agree that any amounts payable under this Paragraph 2 will not be taken into account in determining any such entitlements.
