W.M. "Rusty" Rush is the son of W. Marvin Rush, founder of the Company and Chairman of the Company’s Board of Directors.

Under Article 21.14 of the Texas Insurance Code (the “TIC”), every officer, director and shareholder of a corporation licensed to act as a local recording agent must be individually licensed to act as an insurance agent. An insurance agent is required to be a resident of the State of Texas and pass an examination for a local recording insurance agent’s license. W. Marvin Rush, our Chairman, is licensed to act as an insurance agent in the State of Texas and is therefore qualified to act as the shareholder, director and officer of Associated Acceptance, Inc. (“AA”), the corporation currently affiliated with the Company that is licensed to act as a local recording agent. The Company has acquired, as a wholly owned subsidiary, a managing general agent (the “MGA”) licensed under Article 21.07-3 of the TIC to manage all of the operations of AA. In addition to managing AA, the MGA is qualified to receive any and all commission income that is otherwise payable to AA. The MGA, Mr. Rush and AA have each entered into agreements pursuant to which (i) the MGA manages all operations of AA, (ii) all of the income of AA is paid to the MGA, (iii) the Company transfers such funds to AA as necessary for its operation, and (iv) Mr. Rush has granted the MGA the right to transfer legal ownership of the shares of capital stock of AA at any time to anyone designated by the MGA. Mr. Rush continues to own all of the outstanding stock of AA, subject to his agreements with the MGA prohibiting the transfer of such capital stock.

The Company owns and operates a jet aircraft in connection with its business. The Company generally limits usage of the aircraft to the Chairman and to the Chief Executive Officer for personal purposes to the extent the aircraft is not being utilized for Company business. While the Company does not charge for such use of its aircraft for personal purposes, it does report as taxable income to the Internal Revenue Service the value of the transportation services rendered based upon Internal Revenue Service formulas.
