                 Ternium to Sell Non-Core U.S. Assets

    LUXEMBOURG--(BUSINESS WIRE)--Dec. 19, 2007--Ternium S.A. (NYSE:TX)
announced today that its subsidiary, IMSA Acero, S.A. de C.V., has
entered into a stock purchase agreement with BlueScope Steel North
America Corporation, a subsidiary of BlueScope Steel Limited
(ASX:BSL), for the sale of IMSA's interests in Steelscape, Inc., ASC
Profiles Inc., Varco Pruden Buildings Inc. and Metl-Span LLC. Ternium
will continue to own Steelscape's Shreveport, LA plant, which has a
total annual production capacity of approximately 250,000 metric tons
of galvanized steel and 200,000 metric tons of pre-painted steel.
Ternium also will retain its pre-engineered metal buildings and
insulated steel panels businesses in Mexico.

    The transaction values the assets at US$730 million on a cash-free
and debt-free basis, subject to working capital and other adjustments.
BlueScope Steel will also assume approximately US$20 million in
under-funded pension liabilities. Ternium intends to use the proceeds
of the sale to prepay financial debt.

    The assets being sold accounted for annual net sales of
approximately US$1.2 billion in 2006. Steelscape, excluding the
Shreveport facility, has a total annual production capacity of
approximately 450,000 metric tons of galvanized steel and 300,000
metric tons of pre-painted steel. ASC Profiles and Varco Pruden
Buildings are in the building components and pre-engineered metal
buildings businesses, respectively, while Metl-Span manufactures
insulated steel panels.

    Daniel Novegil, Chief Executive Officer of Ternium, said: "By
selling the assets that are not a strategic fit with our production
system, we seek to enhance our focus on our core businesses in the
Americas and reaffirm our commitment to create value through a
disciplined approach to expansion that is consistent with our regional
strategy. Additionally, we are retaining Steelscape's Shreveport
facility, which we believe can be readily integrated into our
operations as we work to achieve the synergies that are expected to
result from our integration of Grupo Imsa."

    The transaction is subject to U.S. antitrust clearance and other
customary conditions, and is expected to close in the first quarter of
2008.

    Goldman, Sachs & Co. acted as exclusive financial advisor to
Ternium in connection with the transaction.
