2. Qualifying Termination Before the Scheduled Separation Date. The Company will not terminate your employment without Cause before the Scheduled Separation Date. If you voluntarily terminate employment before the Scheduled Separation Date, subject to agreement by the Company and Section 6 below, you shall continue to receive payment of your regular wages through the Scheduled Separation Date and the Retirement Benefits described in Section 3 below. The Scheduled Separation Date or the date of your earlier termination in accordance with this Section 2 is referred to as the “Qualifying Termination Date.”

In the event your employment terminates pursuant to Section 1 or Section 2 above and you: (i) comply at all times with this TSP, and (ii) execute (and take no action to revoke) the Release Agreement to be provided on or about the Qualifying Termination Date (see Section 6 below), you shall be eligible to receive those benefits set forth in Section 4.7 of your Employment Agreement:

d) a pro rata portion of any performance-based restricted stock units granted to you under the Omnibus Plan (excluding any Founders Award) shall remain eligible to vest pro rata based on the date your employment terminates, subject to satisfaction of the performance goals set forth in the applicable award agreement, as determined by the Committee;

f) reimbursements equal to the monthly premiums pursuant to Consolidated Omnibus Budget Reconciliation Act of 1985, as amended for eighteen (18) months, subject to the terms set forth in Section 2.2 of the Company’s Executive Severance Plan.

For purposes of this TSP, “Cause” is defined in Section 4.1 of your Employment Agreement and is made a part hereof as if fully set forth herein.

5. Other Compensation or Benefits. Other than as set forth in Section 3 above, to the extent applicable, you will not receive any additional compensation, severance or other benefits, with the exception of any benefit (other than a severance type benefit), the right to which has accrued and vested, but remains unpaid, as of the date of termination under the express terms of a written employee benefit plan of the Company.

6. Release of Claims. You shall not be eligible to receive any payments or other benefits described in this TSP (other than payments pursuant to Section 7 below) unless you first execute and return a Release Agreement with the twenty-one (21) day period following the Qualifying Termination Date and you do not revoke your consent to the Release Agreement within the seven (7) day period following your execution of the Release Agreement. The Release Agreement will also set forth certain post-employment obligations to which you must adhere following the Qualifying Termination Date. A final copy of the Release Agreement will be provided for your consideration and signature on or about the Qualifying Termination Date. Any Release Agreement signed by you before the Qualifying Termination Date shall be deemed null and void and of no force or effect.

7. Accrued Obligations. Following your last day of employment, you will be paid for accrued, unused vacation hours, if any, based on your base salary in effect as of that time, plus any accrued but unpaid base salary and any unreimbursed business expenses entitled to reimbursement in accordance with Company policies. You are entitled to these payments regardless of whether or not you sign the Release Agreement.
