("Frye") sold to the Shareholder the sole authorized, issued and outstanding share (the "Share") of the common stock of the Company, pursuant to the direction of UCI of GA under that certain Stock Purchase Option and Restriction Agreement by and among the Company, UCI of GA, and Frye, dated March 9, 1998; WHEREAS, in connection with the above-described sale of stock, UCI of GA requires that the Shareholder grant this Option pursuant to which UCI of GA may require that the Shareholder offer to sell any and all shares of the common stock of the Company owned by Shareholder, including but not limited to the Share, to a person or persons selected by UCI of GA in accordance with the terms and conditions set forth herein; and WHEREAS, the Shareholder is the sole shareholder of the Company, and the Share represents all the issued and outstanding capital stock of the Company. NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are acknowledged, the Shareholder hereby irrevocably grants unto UCI of GA and its successors and assigns (the "Optionholder") an option to the person or persons selected by the Optionholder (the "Purchaser") to purchase any and all shares of the common stock of the Company now or hereafter owned by Shareholder, including but not limited to the Share, at the price and upon the terms and conditions described herein, exercisable upon presentation of this Option and payment of the purchase price as follows: 1.

EXERCISE PRICE: Exercise of this Option requires the payment of One Hundred and No/100 ($100.00) Dollars in cash or personal check by the Purchaser to the Shareholder (the "Exercise Price"). 3. OPTION PERIOD: This Option shall expire, and the Shareholder's restrictions hereunder shall terminate, upon the earlier of (i) three years after the effective date of the dissolution of the Company, unless the Company is earlier reinstated pursuant to the Tennessee Business Corporation Code, as amended, in which event this Option shall not terminate; or (ii) the consummation of the exercise of this Option as set forth herein; or (iii) the written consent of UCI of GA. 4.

Closing shall take place at the principal office of UCI of GA in Columbia, South Carolina, or at such other place as the Optionholder and the Shareholder 21 shall agree.
