This Amendment No. 1 amends and supplements the Tender Offer Statement on Schedule TO filed on May 5, 2003 (the "Schedule TO") by Valhi, Inc., a Delaware corporation ("Purchaser"). The Schedule TO relates to the offer by Purchaser to purchase up to 1,000,000 6 5/8% Convertible Preferred Securities, Beneficial Unsecured Convertible Securities, liquidation preference $50 per security (the "Securities"), which represent undivided beneficial ownership interests in the assets of TIMET Capital Trust I, a Delaware statutory business trust (the "Trust"), at a purchase price of $10.00 per Security, net to the seller in cash, upon the terms and subject to the conditions set forth in the Offer to Purchase dated May 5, 2003 (the "Offer to Purchase") and in the related Letter of Transmittal, copies of which were attached to the Schedule TO as Exhibits (a)(1) and (a)(2) (which, together with any amendments or supplements thereto, collectively constitute the "Offer"). The Securities include the associated guarantee by Titanium Metals Corporation, a Delaware corporation ("TIMET"). Capitalized terms used and not otherwise defined herein shall have the meanings assigned to them in the Offer to Purchase or the Schedule TO. Item 1. Summary Term Sheet Item 1 of the Schedule TO is hereby amended and supplemented to include the following information: The second bullet point in the Summary Term Sheet contained in the Offer to Purchase on Page 1 is amended and restated to read in its entirety as follows: o "Valhi, Inc., a Delaware corporation. We may be deemed to be an affiliate of TIMET and the TIMET Capital Trust I, and, along with certain related parties and affiliates, own approximately 42.2% of the outstanding securities of the class that we are offering to purchase and approximately 48.9% of the outstanding shares of common stock of TIMET (approximately 51.7%, assuming full conversion of only such securities we beneficially own into shares of TIMET common stock). See "Section 8. Certain Information Concerning Purchaser." The Summary Term Sheet contained in the Offer to Purchase is further amended and supplemented to include the following information: "RISK FACTORS Before deciding whether or not to tender any of your securities, you should consider carefully the following risks and potential disadvantages of the offer: We did not obtain a third-party valuation or appraisal and did not determine the terms of our offer through arms-length negotiation. We did not base our determination of the terms of our offer on any third-party appraisal or valuation. We established the terms of our offer without any arms-length negotiation. We do not know whether our offer reflects the price that could be realized upon a sale of your securities to another party. You may be able to obtain a higher price for your securities now or in the future from another party. Our offer may not represent fair market value. There is no established or regular trading market for your securities, and trading in the securities has been limited and sporadic. Our offer does not necessarily reflect the price that you would receive if there was an active trading market for your securities. Such prices could be higher than our offer. Our offer is substantially less than the redemption value of the securities. The offer is substantially below the redemption price of the securities. While there is no assurance the securities will ever be redeemed, if they were to be redeemed, it would be at a higher price than our offer. We may be deemed to control TIMET and therefore, subject to the financial capability of TIMET, we could take action to cause TIMET to redeem the securities at some future date. However, we do not presently intend to do so. Holding your securities may result in greater future value. Although we do not believe that a redemption of the securities is currently contemplated, you might receive more value if you retain your securities until such time as the securities are redeemed. Additionally, in the future you may receive a higher value for your securities in market transactions, privately negotiated sales or through subsequent tender offers made by us or other persons. We are not making a recommendation with respect to this offer. We are not making any recommendation to any holder as to whether to tender securities and are remaining neutral towards the offer. We believe that this is a personal investment decision for each holder. Each holder must make its own investment decision as to whether to tender its securities and, if so, how many securities to tender. Each holder should discuss whether to tender its securities with its financial and tax advisors. The sale of your securities is a taxable transaction. If your securities are purchased in the offer, your receipt of cash will be a taxable transaction to you for federal income tax purposes. In general, for federal income tax purposes, you will recognize gain or loss equal to the difference between your adjusted basis in the securities (including any accrued and unpaid distributions through the date of purchase pursuant to the offer) and the amount of cash you receive for those securities. However, your tax consequences from the tender of your securities in the offer can be complicated, and you should consult your own tax advisor to understand how the offer will affect you. If you tender securities to us in this offer, you will no longer be entitled to distributions. If you tender your securities in response to our offer, you will transfer to us all right, title and interest in and to all of the securities we accept, and the right to receive all distributions in respect of such securities on and after the date on which we accept such securities for purchase. Accordingly, for any securities that we acquire from you, you will not receive any future distributions. In addition, no payments will be made in the offer for any distributions that are accrued and unpaid as of the date payment is made for the securities. TIMET has deferred distribution payments on the securities, beginning with the scheduled distribution payment on December 1, 2002. As of May 1, 2003, the total amount of deferred distributions per security was $2.24. If we acquire a sufficient number of securities in this offer, we could own a majority of the outstanding securities and direct some actions relating to the securities. It is possible that, as a result of the offer, we and our affiliates may beneficially own a majority of the outstanding securities. The holders of a majority of the securities have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee under the indenture relating to the guarantee or to direct the exercise of any trust or power conferred upon such trustee under the guarantee. In addition, the holders of a majority of the securities have the right to direct the time, method, and place of conducting any proceeding for any remedy available to certain trustees under the Trust's Declaration of Trust or to direct the exercise of any trust or power conferred upon such trustees under the Declaration of Trust, including the right to direct such trustees to exercise the remedies available to them as a holder of the convertible debentures issued concurrently with the securities. In addition, termination of the Trust requires the consent of at least a majority of the securities. The maturity date of the securities cannot be changed, the principal amount and interest rate of the securities cannot be reduced and the time when interest is due on the securities cannot be extended, in each case without the consent of all of the holders of the securities. We may delay our acceptance of, and payment for, your securities. We reserve the right to extend the period of time during which our offer is open and thereby delay acceptance for payment of any tendered securities. Although you will retain your withdrawal rights during an extension of the offer, the offer may be extended indefinitely, and no payment will be made in respect of tendered securities until the expiration of the offer and acceptance of securities for payment." Item 2. Subject Company Information Item 2 of the Schedule TO is hereby amended and supplemented to include the following information: Section 6 of the Offer to Purchase on page 13 is amended to add the following after the table of sales prices for the TIMET Shares: "The high and low sales prices for the periods indicated for the Securities as reported by NASDAQ are set forth below.

Section 6 of the Offer to Purchase on page 14 is amended to add the following as the last paragraph of Section 6: "All rights of a holder of Securities to receive distributions in respect of Securities tendered in the Offer will be transferred to Purchaser on the date on which Purchaser accepts such Securities for purchase. Accordingly, the current holder of such Securities will not receive any future distributions on such Securities on and after such date. In addition, Purchaser will not make any payments in the Offer for any distributions that are accrued and unpaid as of the date payment is made for the Securities. As of May 1, 2003, the total amount of deferred distributions per Security was $2.24." Section 7 of the Offer to Purchase on page 14 is amended to add the following as the last sentence to the first full paragraph of Section 7. "Purchaser remains responsible for the information contained in this Offer to Purchase." Section 7 of the Offer to Purchase on page 14 is amended to add the following as the second to last paragraph of Section 7: "The Convertible Debentures mature on December 1, 2026 and bear interest at the rate of 6.625% per annum, payable quarterly in arrears. The Convertible Debentures have provisions with respect to interest, redemption, conversion into TIMET Shares and certain other terms substantially similar or analogous to those of the Securities. Interest payment periods may be extended from time to time by TIMET for successive periods not exceeding 20 consecutive quarters for each such period (during which interest will continue to accrue and compound quarterly). Prior to the termination of any extension period, TIMET may further extend such extension period; provided that such extension period may not exceed 20 consecutive quarters and may not extend beyond the maturity date of the Convertible Debentures. Upon the termination of any extension period and the payment of all amounts then due, TIMET may commence a new extension period, subject to certain limitations. No interest will be due and payable during an extension period. The Convertible Debentures are subordinated to all senior indebtedness of TIMET and effectively subordinated to all existing and future indebtedness and liabilities, including trade payables, of TIMET's subsidiaries. The Trust holds $201.241 million principal amount of the Convertible Debentures, representing all of the issued and outstanding Convertible Debentures." Item 3.

Past Contacts, Transactions, Negotiations and Agreements. Item 5 of the Schedule TO is hereby amended and supplemented to include the following information: Section 8 of the Offer to Purchase on page 18 is amended to add the following before the last paragraph of subsection entitled "Certain Relationships and Transactions": "Insurance Matters. Tall Pines Insurance Company ("Tall Pines"), Valmont Insurance Company ("Valmont") and EWI RE, Inc. ("EWI") provide for or broker certain of TIMET's insurance policies. Tall Pines is a wholly owned captive insurance company of Tremont. Valmont is a wholly owned captive insurance company of Purchaser. Parties related to Contran own all of the outstanding common stock of EWI. Through December 31, 2000, a son-in-law of Harold C. Simmons managed the operations of EWI. Subsequent to December 31, 2002, pursuant to an agreement that may be terminated upon 90 days written notice by either party, this son-in-law provides advisory services to EWI as requested by EWI, for which the son-in-law is paid $11,875 per month and receives certain other benefits under EWI's benefit plans. Since March 2003, such son-in-law serves as the chairman of the board of EWI. Consistent with insurance industry practices, Tall Pines, Valmont and EWI receive commissions from the insurance and reinsurance underwriters for the policies that they provide or broker. During 2002, TIMET paid approximately $3.4 million for policies provided or brokered by Tall Pines, Valmont and/or EWI. These amounts principally included payments for reinsurance and insurance premiums paid to unrelated third parties, but also included commissions paid to Tall Pines, Valmont and EWI. Proposed Transaction. On September 19, 2001, Purchaser announced a proposal whereby the shares of the common stock of NL held by Purchaser and Tremont would be transferred to TIMET in exchange for TIMET debt and equity securities. On September 27, 2001, Purchaser withdrew its proposal to TIMET, concluding that the business and financial prospects of NL and TIMET in the then current economic environment would be difficult, resulting in an impairment of the parties ability to properly and adequately value the securities of both companies. Utility Services. In connection with the operations of TIMET's Henderson, Nevada facility, TIMET purchases certain utility services from Basic Management, Inc. and its subsidiaries (referred to collectively herein as "BMI") pursuant to various agreements. A wholly owned subsidiary of Tremont owns approximately 32% of the outstanding equity securities of BMI (representing 26% of the voting securities of BMI). During 2002, fees for such utility services provided by BMI to TIMET were approximately $2.8 million." Item 6. Purposes of the Transaction and Plans or Proposals. Item 6 of the Schedule TO is hereby amended and supplemented to include the following information: The first paragraph of Section 10 of the Offer to Purchase on page 19 is amended and restated in its entirety to read as follows: "Purpose of the Offer. The purpose of the Offer is to acquire Securities for investment purposes. Historically, the titanium metal industry, and therefore TIMET's results of operations, have been highly cyclical. The titanium industry historically has derived a substantial portion of its business from the aerospace industry. The cyclical nature of the aerospace industry has been the principal reason for the historical fluctuations in the performance of titanium companies. Over the past 20 years, the titanium industry had cyclical peaks in mill product shipments in 1989, 1997 and 2001 and cyclical lows in 1983, 1991 and 1999. Demand for titanium reached its highest peak in 1997 when industry mill product shipments reached an estimated 60,000 metric tons. Industry mill product shipments subsequently declined approximately 5% to an estimated 57,000 metric tons in 1998. After falling 16% from 1998 levels to 48,000 metric tons in 1999 and 2000, industry shipments climbed to 55,000 metric tons in 2001. However, primarily due to a decrease in demand for titanium from the commercial aerospace sector, total industry mill product shipments fell approximately 20% to an estimated 44,000 metric tons in 2002. TIMET expects total industry mill product shipments in 2003 will decrease slightly from 2002 levels. Given this highly cyclical nature of TIMET's business, Purchaser believes that the Securities may represent a long-term investment opportunity." Section 10 of the Offer to Purchase on page 19 is amended to add the following as the second paragraph of such Section: "Purchaser did not base its determination of the terms of the Offer on any third-party appraisal or valuation. Purchaser established the terms of the Offer without any arms-length negotiation.
