For purposes of this Section 2, no act or failure to act on your part shall be considered “willful” unless it is done, or omitted to be done, by you in bad faith or without reasonable belief that your action or omission was in the best interest of the Company.

3. Severance Pay and Benefits . Unless your employment has been terminated by reason of death or Cause as provided in Section 2 and subject to the terms of this Agreement, the Company will pay or provide to you:

a. Salary Continuation . The Company will pay you an amount equal to two times the sum of your annual Base Salary ($325,000) and your Annual Incentive Plan (“AIP”) bonus opportunity at your 2008 target rate ($162,500) as salary continuation which will be paid over 24 months following the Termination Date. Payments of this salary continuation amount of $975,000 will be paid in equal installments at the times and in the manner consistent with Company payroll practices for executive employees, and each installment payment shall be considered a separate payment and not one of a series of payments for purposes of Section 409A of the Code; provided, however, that notwithstanding the foregoing, installments (beginning with the first installment to be made and continuing with subsequent installments in order of time) with an aggregate value of $550,000 shall be paid in a lump sum on or before December 31, 2008 and the remaining aggregate installments ($425,000) shall continue to be paid at the times they would have been paid had such lump sum payment not been made. Payments made on or before June 30, 2009 will have the current U.S. hypothetical tax rate deducted. Payments made after June 30, 2009 will have all federal taxes deducted, as applicable; provided, however, if you return to the U.S. after June 30, 2009, any state and local taxes may also be deducted.

At your option, you may continue your coverage for a period of 24 months, inclusive of 18 months of COBRA. Please contact the JDI Service Center at (866) 391-0760 for more detailed information. If you elect any such continued coverage, the Company will subsidize the medical, vision and dental rates for the 24 months of continuation coverage following your Termination Date so that for the same coverage you will pay the same amount of contribution as if you were an active employee; provided, however, that following the end of your 18 months of COBRA continuation coverage and continuing through the end of the 24 month period, with respect to any such medical, dental and vision benefits provided under a self-insured medical reimbursement plan (within the meaning of Section 105(h) of the Internal Revenue Code), (a “Self-Insured Medical Plan”), for which you have elected coverage, the reimbursement of an eligible medical expense must be made on or before the last day of the calendar year following the calendar year in which the expense was

On or about January 31, 2012, the Company will make a payment in cash to you equal , on an after-tax basis, to (i) the amount, if any, you paid in premium payments during the immediately preceding calendar year for such continued coverage under any Self-Insured Medical Plan for the period following the end of the 18-months of COBRA continuation coverage through the end of the 24-month period, exceeds (ii) the amount you would have paid if you had remained in employment during such period.

c. Choice Benefits . As with the health benefits, the coverage you elected will cease on your Termination Date.

d. (i) 2008 AIP . You will receive a 2008 AIP bonus payment at your 2008 target rate ($162,500).
