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 hold. The CMRT directly holds approximately 0.2% of the Outstanding Shares and 0.1% of the outstanding shares of Valhi common stock.

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.

Valhi is the direct holder of 100% of the outstanding common stock of Valmont and may be deemed to control Valmont. Pursuant to Delaware law, Valhi treats the shares of Valhi common stock that Valmont and the subsidiary of NL own as treasury stock for voting purposes and for the purposes of this Statement such shares are not deemed outstanding. Mr. Harold C. Simmons is chairman of the board and chief executive officer of TGI, Valhi, VGI, National, NOA, Dixie Holding, Dixie Rice, Southwest and Contran.
