AGREEMENT In consideration of First Financial and the Company entering into the Stock Purchase Agreement and other good and valuable consideration, the parties hereby agree as follows: 1. Capitalized Terms. All capitalized terms used herein without express definition shall be defined as provided in the Stock Purchase Agreement. 2. Part 7.6 Indemnification. In the event Company elects to terminate the Stock Purchase Agreement in accordance with Part 7.6 of the Disclosure Letter, First Financial will notify the members of the Shareholder Group.

Damage Adjustment. If any Damages suffered by the Company shall result in any tax saving, entitlement to insurance recovery or other monetary benefit to the Company, then the amount of such Damages payable by the Shareholder Group shall be adjusted to reflect such benefit. 2 4. Severally Defined. As used herein, "Severally" shall mean that the amount payable by each member of the Shareholder Group shall equal the total dollar amount of the Damages, multiplied by a fraction the numerator of which is the number of shares of First Financial owned by such shareholder as of the date hereof (as shown on Exhibit A), and the denominator of which is the total number of shares held by all members of the Shareholder Group (as shown on Exhibit A), but in no event to exceed an amount equal to the Purchase Price multiplied by such fraction. 5. Section 10 Indemnification. Subject to the limitations of Section 6, the Shareholder Group hereby agrees to assume, Severally, the indemnification obligations of First Financial to the Company under Section 10 of the Stock Purchase Agreement, provided that First Financial's net worth (computed without deduction for payments made by First Financial as a result of the indemnity provided in Section 10 of the Stock Purchase Agreement but otherwise in accordance with GAAP) is below $3,000,000 as of the date First Financial's liability for the claim is determined. 6. Liability Cap. The total of all indemnification payments payable under Section 5 hereof shall not exceed the sum of $3,000,000, less the net worth of First Financial, determined as provided in Section 5 hereof by First Financials' regular accountants, as of the date First Financial's liability for the claim is determined, and less any indemnification payments made by First Financial pursuant to Section 10 of the Stock Purchase Agreement through the date on which First Financial's liability for the claim is determined. 7. First Financial's Obligation. First Financial agrees that, at the earliest possible time, it will reimburse the Shareholder Group or any one of them, for any payments made hereunder and the expenses associated therewith. 8.
