WHEREAS, consistent with the requirements of Section 409A of the Internal Revenue Code (“Code”) and Treasury Notice 2005-01, Trinity Bank and the Executive wish to amend and supplement the Employment Agreement by this Agreement to provide that the payment to which the Executive shall become entitled as a result of the Change in Control shall be deferred and paid commencing in 2010, over a period of ten (10) years; and

WHEREAS, this Supplemental Agreement shall also provide that at the effective time of the Merger, the Employment Agreement shall terminate and Trinity Bank and the Executive shall have no further obligations thereunder, the only continuing obligations being those set forth in this Supplemental Agreement; and

WHEREAS, none of the conditions or events included in the definition of the term “golden parachute payment” that is set forth in section 18(k)(4)(A)(ii) of the Federal Deposit Insurance Act [12 U.S.C. 1828(k)(4)(A)(ii)] and in Federal Deposit Insurance Corporation Rule 359.1(f)(1)(ii) [12 CFR 359.1(f)(1)(ii)] exists or, to the best knowledge of the Bank, is contemplated insofar as either of the Bank or any of its subsidiaries is concerned.

NOW THEREFORE, in consideration of these premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows.

(In May 2005, the applicable long-term federal rate is 5.72%)

(b) Thereafter, the amount deferred shall be annuitized using the AFR and shall be paid in equal annual installments for a period of ten years, commencing on the first business day in January 2010 and continuing through the first business day in January 2019.

(c) In the event of the Executive’s death prior to the final payment set forth herein, the remaining payments shall be made to the Executive’s beneficiary(ies) designated by the Executive in writing and attached to this Supplemental Agreement as Exhibit A.
