July 16, 1996 BY HAND DELIVERY Board of Directors First Bancshares, Inc. 131 Main Street Grove Hill, Alabama 36451 Gentlemen: On behalf of United Security Bancshares, Inc., ("United") and United Security Bank, I am pleased to submit the following merger-of-equals proposal: 1. Merger. Subject to the terms and conditions set forth in this letter and to a complete due diligence review of each party to this letter and the negotiation and execution of a Definitive Agreement and Plan of Reorganization (the "Definitive Agreement"), United proposes a "merger of equals" whereby First Bancshares, Inc. ("FBI") will be merged with and into United and the subsidiary banks of each party would be merged into one entity. The Definitive Agreement will contain a requirement of applicable regulatory and shareholder approvals, among other terms, conditions, representations and indemnifications from parties as are customary in transactions of this nature. By executing this letter, FBI represents to us that there are currently outstanding 239,843 shares of common stock of FBI (the "Common Stock"), and there are no other options, warrants, rights or convertible securities (collectively, the "Rights") that are exercisable for shares of Common Stock or other equity securities of any description of FBI. If the transaction is consummated, each share of Common Stock will be converted into 5.8321 shares of common stock of United. The exchange ratio will be adjusted for any stock splits and stock dividends declared subsequent to the date of this letter. 2. Due Diligence: Confidentiality. United and FBI agree to hold any materials obtained from the other party in confidence and to use such materials only to evaluate the proposed transaction. If the proposed transaction is not consummated, each party shall promptly return all such materials. Nothing contained herein shall preclude either party from using information publicly available or received from third parties for purposes other than the proposed transaction.

Executive Officers. At closing, Jack Wainwright, currently President and Chief Executive Officer of United, shall enter into a three-year contract to continue as President and Chief Executive Officer of the resulting entity, and Fred Huggins, currently Chairman and Chief Executive Officer of FBI, shall serve as chairman and CEO of a finance subsidiary of the resulting organization. The Chairman of the resulting holding company will be Jim Miller, with Fred Huggins and Ray Sheffield serving as Vice Chairmen. The Chairman of the resulting bank will be Fred Huggins, with Don Nichols and Hardie Kimbrough serving as Vice Chairmen. 5. Incentive Program.
