FOR IMMEDIATE RELEASE
---------------------



                       WHEELING-PITTSBURGH CORPORATION AND

          COMPANHIA SIDERURGICA NACIONAL ANNOUNCE DEFINITIVE AGREEMENT



WHEELING, WV and SAO PAOLO, BRAZIL, October 25, 2006 - Wheeling-Pittsburgh
Corporation (NASDAQ: WPSC) and Companhia Siderurgica Nacional (NYSE: SID) today
announced that they have entered into a definitive agreement in which
Wheeling-Pittsburgh will acquire the North American assets of CSN, creating a
strong, well-capitalized steel producer with a more flexible cost structure,
broader value-added product offering, access to CSN's product and process
technology, and significant long-term earnings potential. The definitive
agreement reflects the strategic arrangement announced on August 3, 2006.

James G. Bradley, Chairman and Chief Executive Officer of Wheeling-Pittsburgh
stated, "This merger agreement marks a new beginning for steelmaking at
Wheeling-Pittsburgh and in the Ohio and Monongahela valleys. We are confident
that the agreement positions Wheeling-Pittsburgh to deliver sustainable earnings
as well as solid future cash flows. CSN is a world-class, fully integrated steel
producer with impressive margins and an enviable cash flow, and we look forward
to partnering with them as we take Wheeling-Pittsburgh to the next level."

Under the terms of the agreement, CSN will contribute its modern steel
processing facility in Terre Haute, Indiana with current annual pickled and
oiled, cold rolled and galvanized products of 1 million tons, provide
Wheeling-Pittsburgh exclusive U.S. and Canadian distribution rights for CSN's
flat-rolled steel products and commit to a ten-year slab supply agreement, which
will provide a long-term, guaranteed supply of high-quality slabs on favorable
payment terms.

CSN will also contribute $225 million in cash through the issuance by the
combined company of a convertible debt security that, with the consent of the
United Steelworkers, can be converted into equity in three years. Of the $225





million, approximately $150 million will be used for transformative capital
improvements - $75 million to build a new energy-efficient furnace that would
increase Wheeling-Pittsburgh's hot strip mill capacity to 4 million tons, and
the balance to add a second galvanizing line at Terre Haute. The remaining $75
million will be used to enhance the combined company's liquidity position.

Marcos Lutz, Managing Director for Infrastructure and Energy, CSN, said, "This
transaction will combine CSN's modern North American assets, capital, slab
supply and management expertise with Wheeling-Pittsburgh's production
capabilities to benefit all of our North American stakeholders - shareholders,
employees, customers and the communities of which we are a part. Together, we
will create an integrated, value-added production chain that will result in a
more flexible cost structure, broader value-added product offerings and
significant incremental earnings potential."

This agreement marks the culmination of an extensive process by
Wheeling-Pittsburgh involving a number of potential suitors, as well as the
United Steelworkers. In accordance with an agreement reached in September
between the Company and the USW, the USW had until October 15, 2006 to submit a
bid or assign its right to a designee. No such bid or designation has been made
by the USW.

Upon completion, the existing Wheeling-Pittsburgh Corporation as well as CSN's
operating subsidiary in Terre Haute will become wholly owned subsidiaries of a
new holding company, which intends to seek a North American stock exchange
listing. A new Board of Directors will be created, which will include Mr.
Bradley as Chairman, two USW directors, five independent directors, and three
directors designated by CSN. Wheeling-Pittsburgh's current shareholders will
receive 50.5% of the combined company. The remaining 49.5% will be held by CSN,
which may increase its ownership to 64% upon conversion of the $225 million
debt.

Bradley concluded, "Our Board has demonstrated its open-mindedness in creating
value for our shareholders and has repeatedly shown its commitment to evaluating
all strategic options, including remaining independent. The Board has concluded
that the combination with CSN represents a compelling opportunity at this time.
We will continue to engage in a productive dialogue with our shareholders and
welcome further input as we work constructively through the merger process."

The Company and CSN expect to file a preliminary proxy statement and prospectus
regarding the CSN transaction with the SEC as soon as possible.

The Company's Annual Meeting of Shareholders to elect its Board of Directors is
scheduled for November 17, 2006 at the White Palace in Wheeling, WV. In
addition, the Company expects to hold a Special Meeting of Stockholders in
January 2007 to vote on the proposed transaction with CSN.

In addition, effective October 25, 2006, the Company has terminated its "poison
pill" provision that was adopted in February 2005.
