Together, Valhi, NL and Tremont may be deemed to control the Company. TIMET is the direct holder of 100% of the outstanding shares of common stock of TFMC and may be deemed to control TFMC. Tremont, Harold C. Simmons' spouse, the CMRT and Valhi are the holders of approximately 39.6%, 14.4%, 12.1% and 1.3% of the outstanding shares of TIMET common stock. Tremont may be deemed to control TIMET. The ownership of Mr. Simmons' spouse is based on the 1,600,000 shares of TIMET's 6 3/4% Series A Convertible Preferred Stock, par value $0.01 per share (the "Series A Preferred Stock"), that she directly owns, which are convertible into 2,666,666 shares of TIMET common stock. The ownership of Valhi includes 24,500 shares of TIMET common stock that Valhi has the right to acquire upon conversion of 14,700 shares of Series A Preferred Stock that Valhi directly holds. The percentage ownership of TIMET common stock held by each of Ms. Simmons and Valhi assumes the full conversion of only the shares of Series A Preferred Stock she or Valhi owns, respectively. Valhi, Tremont and TFMC were the direct holders of approximately 62.2%, 21.1% and 0.5%, respectively, of the outstanding shares of NL common stock.

Substantially all of Contran's outstanding voting stock was held by trusts established for the benefit of certain children and grandchildren of Harold C. Simmons (the "Trusts"), of which Mr. Simmons was the sole trustee. As sole trustee of each of the Trusts, Mr. Simmons has the power to vote and direct the disposition of the shares of Contran stock held by each of the Trusts. Mr. Simmons, however, disclaims beneficial ownership of any shares of Contran stock that the Trusts held. The Foundation directly held approximately 0.9% of the outstanding shares of Valhi common stock. The Foundation is a tax-exempt foundation organized for charitable purposes. Harold C. Simmons is the chairman of the board of the Foundation and may be deemed to control the Foundation. The CDCT No. 2 directly held approximately 0.4% of the outstanding Valhi common stock. U.S. Bank National Association serves as the trustee of the CDCT No. 2. Contran established the CDCT No. 2 as an irrevocable "rabbi trust" to assist Contran in meeting certain deferred compensation obligations that it owes to Harold C. Simmons. If the CDCT No. 2 assets are insufficient to satisfy such obligations, Contran is obligated to satisfy the balance of such obligations as they come due. Pursuant to the terms of the CDCT No. 2, Contran (i) retains the power to vote the shares of Valhi common stock held directly by the CDCT No. 2, (ii) retains dispositive power over such shares and (iii) may be deemed the indirect beneficial owner of such shares. The CMRT directly held approximately 12.1% of the outstanding shares of TIMET common stock and 0.1% of the outstanding shares of Valhi common stock. Valhi established the CMRT as a trust to permit the collective investment by master trusts that maintain the assets of certain employee benefit plans Valhi and related companies adopt. Mr. Simmons is the sole trustee of the CMRT and a member of the trust investment committee for the CMRT. Mr. Simmons is a participant in one or more of the employee benefit plans that invest through the CMRT.

NL and a subsidiary of NL directly owned 3,522,967 shares and 1,186,200 shares, respectively, of Valhi common stock. Pursuant to Delaware law, Valhi treats the shares of Valhi common stock that NL and the subsidiary of NL own as treasury stock for voting purposes and for the purposes of percentage calculations such shares are not deemed outstanding. Harold C. Simmons is the chairman of the board and chief executive officer of each of the Company and NL, vice chairman of the board of TIMET, and the chairman of the board of each of Tremont, Valhi, VGI, National, NOA, Dixie Holding, Dixie Rice, Southwest and Contran. By virtue of the holding of the offices, the stock ownership and his services as trustee, all as described above, (a) Harold C.
