SAO PAOLO, BRAZIL, NOVEMBER 14, 2006 - Companhia Siderurgica Nacional ("CSN")

      "Company"), CSN will contribute an incremental $50 million of cash to
      Wheeling-Pittsburgh, in addition to the contribution of: CSN LLC; the Slab

      The revised offer follows continued conversations with major
      Wheeling-Pittsburgh shareholders, and is responsive to their diverse aims
      and objectives. This offer:

o     IMPROVES THE ECONOMIC CONSIDERATION TO THE UNDERLYING MERGER, which
      responds to questions regarding the appropriateness of the value of CSN's
      assets being contributed;
o     INCREASES THE "CASH" COMPONENT BY RAISING THE VALUE OF THE DEPOSITARY "B"
      SHARE TO $32, and represents $24.41 in present value assuming a 7%
      yield-to-maturity, which implies a 34% premium to the closing price of
      $18.24 as of November 13, 2006. As an expression of its confidence in the
      benefits of the merger, CSN will take the risk that if it is unable to
      resolve any successorship issues with the USW, it will commit to sell
      shares in order to remain below 50% of ownership while purchasing the B
      shares;
o     STRENGTHENS THE BALANCE SHEET, by increasing the equity contribution by
      $50 million cash and reducing the Convertible Debt by $50 million;
o     RETAINS THE MERGER STRUCTURE THAT PROVIDES SHAREHOLDERS FREEDOM OF CHOICE
      TO TAKE EITHER "B" SHARE CASH OR EQUITY UPSIDE, which is in response to
      significant shareholder interest in continuing its equity participation;
o     IMPROVES SHAREHOLDERS' ABILITY TO PARTICIPATE FURTHER IN FUTURE UPSIDE,
      through a rights offering at the end of the first year following
      completion of the merger; and
o     PROVIDES CURRENT WHEELING-PITTSBURGH SHAREHOLDERS WITH THE ABILITY TO
      MAINTAIN CONTROL EQUAL TO THEIR 50.5% THROUGH THE COMBINED COMPANY'S
      MERGER CONSIDERATION AND RIGHTS OFFERING

Marcos Lutz, managing director for infrastructure and energy for CSN, said "This
is a winning proposition for all Wheeling-Pittsburgh shareholders. We believe we
have addressed each aspect of our offer, and have improved each component
significantly. Wheeling-Pittsburgh shareholders will have more hard value, more
options, more control and a stronger combined company. We continue to strongly
believe that the proposed combination of our North American assets with
Wheeling-Pittsburgh provides significant value creation, and this enhanced offer
provides further benefits to Wheeling-Pittsburgh shareholders.

"With the annual meeting of shareholders at the end of this week, it is now time
for Wheeling-Pittsburgh shareholders to decide. Shareholders can choose to
accept this transaction, if the current directors are re-elected," concluded Mr.
Lutz.

Further, John Hastings, Managing Director of RBC Dain Rauscher, the agent bank
for Wheeling-Pittsburgh's federally guaranteed loan said, "We welcome
improvements to Wheeling-Pittsburgh's balance sheet, and enhancing the credit
worthiness of Wheeling-Pittsburgh will be viewed as a positive by the banking
group. The capital contribution contemplated by this revised proposal appears to
meet those goals."

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

On November 6, 2006, the companies announced an enhanced proposal, under which
for each share of Wheeling-Pittsburgh, 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 percent 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.
