         Ternium to Obtain Control of Mexico-Based Grupo Imsa

    LUXEMBOURG--(BUSINESS WIRE)--April 30, 2007--Ternium S.A.
(NYSE:TX) announced today that it has entered into a definitive
agreement under which it expects to obtain control of Grupo Imsa
S.A.B. de C.V. in Mexico for a total consideration (equity value) of
approximately US$1.7 billion.

    Under the agreement, Ternium, or any of its subsidiaries, will
make a tender offer in accordance with applicable Mexican law for all
of the issued and outstanding share capital of Grupo Imsa at a price
of US$6.40 per share. Concurrently with the consummation of the tender
offer, Grupo Imsa's majority shareholders, owning approximately 90.4%
of Grupo Imsa's issued and outstanding share capital, will have their
shares redeemed in cash at the same price per share.

    Ternium will finance the transactions primarily through debt, for
which bank commitments have been secured.

    Paolo Rocca, Ternium's Chairman commented: "Upon the completion of
this transaction, Ternium will strengthen its position in North
America, where more than 60% of its revenues will be concentrated. The
integration of Imsa will expand Ternium's industrial capabilities in
value added steel products in Mexico and in the USA, where it will
have a team of more than 13,000 highly trained and committed
employees."

    The transaction is subject to Mexican and U.S. antitrust
clearances, approval by the Mexican securities regulator, and other
customary conditions. It is expected to close in the third quarter of
2007.
