Mr. Harold C. Simmons is chairman of the board of Tremont, Valcor, Valhi, VGI, National, NOA, Dixie Holding, Dixie Rice, Southwest and Contran and chairman of the board and chief executive officer of NL.

However, Mr. Simmons disclaims such beneficial ownership of the Shares beneficially owned, directly or indirectly, by any of such entities, except to the extent of his individual vested beneficial interest, if any, in the assets the CMRT or his interest as a beneficiary of the CDCT No. 2.

Purpose of Transaction. Item 4 is amended as follows. TFMC purchased the Class A Shares reported in Item 5(c) in order to increase its equity interest in the Company. On May 20, 2004, NL announced that as part of its plan to diversify its holdings and business interests, NL intends to enter into discussions with Valhi regarding the possible acquisition of up to the approximately 68.6% of the outstanding Shares directly held by Valhi and Valcor. In the announcement, NL stated that it had already formed a committee of independent directors to consider and negotiate the potential terms pursuant to which NL might purchase a controlling interest in CompX from Valhi and Valcor. There can be no assurance as to the final terms of such a transaction or that any such transaction will be consummated, and no agreement or understanding regarding the potential terms of any such transaction have been proposed. Depending upon their evaluation of the Company's business and prospects, and upon future developments (including, but not limited to, performance of the Class A Shares in the market, availability of funds, alternative uses of funds, and money, stock market and general economic conditions), any of the Reporting Persons or other entities that may be deemed to be affiliated with Contran may from time to time purchase Class A Shares, and any of the Reporting Persons or other entities that may be deemed to be affiliated with Contran may from time to time dispose of all or a portion of the Class A Shares held by such person, or cease buying or selling Class A Shares. Any such additional purchases or sales of the Class A Shares may be in open market or privately negotiated transactions or otherwise.
