RELEASE DATE: NOVEMBER 6, 2006

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

              CSN ENHANCES EXISTING PROPOSAL TO WHEELING-PITTSBURGH
          SHAREHOLDERS; WHEELING-PITTSBURGH BOARD ENDORSES ENHANCEMENT
                           AS BEST CURRENT ALTERNATIVE

WHEELING, WV and SAO PAOLO, BRAZIL, November 6, 2006 -Companhia Siderurgica
Nacional (CSN) (NYSE: SID) and Wheeling-Pittsburgh Corporation (NASDAQ: WPSC)
today announced that CSN has offered Wheeling-Pittsburgh an enhancement to its
existing agreement with Wheeling-Pittsburgh. The board of Wheeling Pittsburgh
Corporation has received and endorsed the new proposal as the best alternative
currently available to the Company and its shareholders.

Under the Agreement and Plan of Merger previously announced on October 24, 2006,
the parties agreed to a merger of Wheeling-Pittsburgh with a subsidiary of CSN,
as a result of which the Wheeling-Pittsburgh shareholders would receive 50.5% of
the combined entity and CSN would own the remaining 49.5%. The combined entity
would be known as Wheeling-Pittsburgh Corporation. CSN also agreed to contribute
$225 million in cash through the issuance by the combined company of a
convertible debt security.

Under the enhanced proposal, for each share of Wheeling-Pittsburgh Corporation,
shareholders will have the choice of electing to receive either i) a share of
common stock in the new combined company ("A Share"); ii) a Depositary Share
that requires CSN to pay $30 per share in cash four years after the merger ("B
Share"); or iii) a combination of A and B Shares. Each B share will represent
the same class of common stock as the A Share that is deposited with a
depositary and will be subject to a mandatory purchase by CSN for $30 per share
on the 4th anniversary of the merger. The total number of B Shares will be
limited to 50% of the total of A and B Shares issued in the merger. The B shares
will be listed for trading on the NASDAQ. CSN and the Company are in discussions
to finalize the enhancement, subject to an amendment of the existing definitive
agreements.




James G. Bradley, Chairman and Chief Executive Officer of Wheeling-Pittsburgh
stated "The existing proposal represented the best strategic option for
Wheeling-Pittsburgh shareholders at the time, continues to provide our
shareholders an opportunity to realize significantly greater value, and
positions Wheeling-Pittsburgh for future success. This enhanced proposal
improves upon the previous proposal by providing the benefit of choice to
shareholders and expressing the confidence that CSN has in this combination.
Both CSN and the Company believe that the combined company will create
significantly enhanced value going forward, and this alternative provides
shareholders an opportunity to cash in on some of that value today at a
significant premium to the current stock price if they so choose. Since this
Company emerged from bankruptcy just over three years ago, our employees have
worked hard and with full commitment to making Wheeling-Pittsburgh a success.
CSN's enhanced proposal validates the extent of our employees' contributions and
the great strides this Company has made in a relatively short period of time."

Marcos Lutz, Managing Director for Infrastructure and Energy, CSN, said, "We
firmly believe in the value creation underlying the combination of our companies
and are confident that significant synergies will be achieved. We also wanted to
be responsive to what we have heard from shareholders and present this revised
proposal which essentially offers them an attractive cash alternative. A number
of financial institutions have volunteered to monetize the B Shares for
shareholders, thereby establishing a market and price for these B Shares
immediately."

Bradley concluded, "The paramount focus for our Board is creating shareholder
value, and we are committed in pursuing the best transaction available to our
shareholders. In addition to continuing to be open to bona fide third party
offers, we continue to be in discussion with CSN to improve its current offer.
In such effort, we are in active discussions with CSN in which CSN would allow
existing Wheeling-Pitt shareholders to participate in the economic upside of the
shares underlying the $225 million Convertible Debt. While this aspect of
discussions are in preliminary stages and many details such as tax and legal
structuring need to be addressed, this is another indication of our commitment
to create additional value for our shareholders and CSN's willingness to share
the potential upside benefits of this combination."

Under the terms of the agreement already announced, 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.

The Company and CSN expect to file a preliminary joint 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.
