         Sidor and the Venezuelan Government Sign Cooperation Agreement

     LUXEMBOURG--(BUSINESS WIRE)--August 24, 2007--Ternium S.A. (NYSE:TX)
announced today that its Venezuelan subsidiary Sidor and the Venezuelan
government have entered into a three-year cooperation agreement, pursuant to
which Sidor will increase its involvement in social investment programs in that
country and will enhance its efforts to develop Venezuela's steel value chain,
with particular emphasis on supporting small- and medium-sized enterprises.

     Under the agreement, Sidor has agreed, among other initiatives, to:

     --   Give priority to the Venezuelan domestic market over the international
          market in its sales of products;

     --   Set its pricing policy in the Venezuelan market by reference to
          comparable average export prices in a given period;

     --   Grant a 2% discount to certain Venezuelan entities, such as
          cooperatives and social production companies, and a 4% discount to
          foster special purpose social investment and economic development
          programs in the country;

     --   Form a technical commission with CVG Ferrominera Orinoco C.A., the
          state-owned company responsible for mining and commercializing
          Venezuela's iron ore, to analyze the quantity, quality and price of
          iron ore to be supplied by Ferrominera to Sidor; and

     --   Facilitate the transfer to the Venezuelan government of the operation
          of the Sidor port on the Orinoco River, as provided by Venezuelan law,
          with due assurances to the continuity of Sidor's operations.

     In addition, Sidor confirmed its interest in making capital expenditures at
its Venezuelan facilities of approximately US$500 million from 2007 through
2012, of which approximately US$70 million will be earmarked toward an
environmental protection plan.
