B. Mr. Cummiskey has tendered his resignation as an officer of Chesapeake and the Parties desire to set forth the terms of his separation from employment with Chesapeake, effective February 24, 2012.

NOW, THEREFORE, in consideration of the terms and conditions contained herein and other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, the Parties hereto, intending to be legally bound, agree as follows:

1. Termination of Employment; Employment Agreement. Mr. Cummiskey’s employment is governed by an employment agreement dated December 31, 2009 (“Employment Agreement”). All terms and conditions of the Employment Agreement remain in force and are supplemented by the terms of this Agreement. Specifically, Mr. Cummiskey acknowledges that he is and will remain bound by the terms of the Employment Agreement that survive its termination, including but not limited to the Covenants in Section 9, and that the same remain in full force and effect and survive the termination of his employment with the Company. Mr. Cummiskey’s termination of employment shall be effective as of close of business on February 24, 2012 (“Date of Termination”). This date is Mr. Cummiskey’s last day of active full-time employment. By signing below, Mr. Cummiskey acknowledges his resignation from all positions with the Company and its affiliates effective on the Date of Termination.

2. Release by Mr. Cummiskey.

In exchange for the gross sum of $181,500 to be distributed as set forth below, transfer to Mr. Cummiskey of free and clear title to the Company-owned automobile currently in Mr. Cummiskey’s possession, and other good and valuable consideration, the sufficiency of which is hereby acknowledged, Mr. Cummiskey does hereby release and forever discharge Chesapeake, its subsidiaries, divisions, affiliated companies, predecessors, successors and assigns, as well as the shareholders, directors, officers, administrators, agents, and current and former employees of all of the foregoing, personally and in their respective capacities, and any other person or entity representing or succeeding to any such person or entity (collectively referred to hereafter as “Chesapeake”), from any and all claims, demands, rights, charges, actions, interests, debts, liabilities, lost compensation, lost benefits, damages, costs, interest, attorneys’ fees, and expenses, or causes of action of whatever type or nature, whether legal or equitable, whether in tort or in contract, whether known or unknown to him which Mr. Cummiskey may now have against Chesapeake, either individually, jointly, or severally, based upon acts which have occurred from the beginning of time to the date of this Agreement.

This release further includes a release of any rights or causes of action Mr. Cummiskey may have under Delaware statutory and common law, including any claim for or right to interest, attorneys’ fees, costs and expenses thereunder. This release does not, however, relinquish Mr. Cummiskey’s right to receive any accrued but as yet unpaid salary, vacation pay, reimbursement for properly documented and incurred business expenses, or other amounts vested, due and owing under Company benefit plans.

The S181,500 gross payment shall be made as follows: within five business days of the Date of Termination, a gross payment in the amount of $91,500 shall be made to Mr. Cummiskey, with nine additional payments in the amount of $10,000 each, payable on the first business day coincident with or next following the first day of eaeh calendar month from April through December, 2012.

In addition to the gross cash payment set forth above, the Company will also provide Mr. Cummiskey with reasonable outplacement services for a period of time not exceeding six months from the Date of Termination.

3. Final Compromise; No Admissions. This Agreement is entered into by the Parties for the purpose of compromising and settling all matters between and among them.

4. Written Affirmation of No Present Violation. Mr. Cummiskey hereby certifies and warrants that he is not presently aware of any unreported violation of Chesapeake’s Business Code of Ethics and Conduct or other Company policy and that he is not presently aware of any work-related injury not properly disclosed to the Company.

5. Enforcement. Mr. Cummiskey acknowledges and agrees that the payments to be made under Section 2 of this Agreement are contingent upon his continuing compliance with the terms of this Agreement and the covenants under his Employment Agreement. In the event of any violation by Mr. Cummiskey of his obligations under this Agreement or the Employment Agreement, the Company shall have the right to cease all future payments to Mr. Cummiskey in its sole discretion. Notwithstanding the foregoing, this right to terminate the payments due hereunder shall in no event be the Company’s exclusive remedy with respect to its rights to enforce the terms of this Agreement and the Employment Agreement.
