Ternium Further Updates Market on Sidor Nationalization Process

LUXEMBOURG -- (MARKET WIRE) -- May 13, 2008 -- Ternium S.A. (NYSE: TX) announced that Decree Law 6058 regulating the steel production activity in the Guayana, Venezuela region (the "Decree") became effective today upon its publication on Venezuela's Official Gazette. The Decree represents a further step towards the nationalization of Ternium's majority owned subsidiary Sidor.

The Decree orders that Sidor and its subsidiaries and affiliated companies be transformed into state-owned enterprises ("empresas del estado"), with the government owning not less than 60% of their share capital.

The Decree provides for the creation of two committees. A transition committee shall be created to join Sidor's board of directors and to ensure that control over the current operations of Sidor and its subsidiaries and affiliated companies is transferred to the government on or prior to June 30, 2008. A separate committee, composed of representatives of the government and the private shareholders of Sidor and its subsidiaries and affiliated companies, shall be formed to negotiate over a 60-day period a fair price for the shares to be transferred to the State, together with the terms and conditions of the possible participation of such private shareholders in the share capital of the state-owned enterprises.

The Decree also states that, in the event the parties fail to reach agreement regarding the terms and conditions for the transformation of Sidor and its subsidiaries and affiliated companies into state-owned enterprises by the expiration of the 60-day period, the Ministry of Basic Industries and Mining shall assume control and exclusive operation, and the Executive Branch shall order the expropriation of the shares of the relevant companies. No valuation criteria for the shares to be transferred to the State are provided, except that any expropriation compensation shall include neither lost profits ("lucro cesante") nor indirect damages.

Finally, the Decree specifies that all facts and activities thereunder are subject to Venezuelan law and any disputes shall be submitted to Venezuelan courts.

President Chávez has announced that Minister Rodolfo Sanz shall preside over the transition committee created by the Decree and shall join Sidor's management or board of directors.

While continuing to reserve all of its rights under contracts, investment treaties and Venezuelan and international law, and in order to mitigate damages, Ternium is prepared to continue discussions with the Venezuelan government regarding the fair and adequate terms and conditions under which all or a significant part of Ternium's interest in Sidor should be transferred to the government.
