FOR IMMEDIATE RELEASE

                    CSN PROVIDES SIGNIFICANTLY IMPROVED OFFER
                       TO WHEELING-PITTSBURGH SHAREHOLDERS

                               New Offer Includes:

                 Increased Contribution by CSN into the Merger,
                        Strengthening the Balance Sheet;

       Ability for Wheeling-Pittsburgh Shareholders to Participate Further
                    in Upside Potential of Combined Company;

                   Higher Cash Value for Depositary "B" Shares

                  SAO PAOLO, BRAZIL, NOVEMBER 14, 2006 Companhia Siderurgica
Nacional ("CSN") (NYSE: SID) today sent a letter to the Board of Directors of
Wheeling-Pittsburgh Corporation (NASDAQ: WPSC) containing a substantially
enhanced offer to Wheeling-Pittsburgh shareholders as they consider the pending
merger of Wheeling-Pittsburgh with CSN's North American assets.

                  Specifically, the letter outlines the following:

o     As consideration for CSN's 49.5% interest in the combined company (the
      "Company"), CSN will contribute an incremental $50 million of cash to
      Wheeling-Pittsburgh, in addition to the contribution of: CSN LLC; the Slab
      Supply Agreement, that provides very favorable working capital terms and
      credit to Wheeling-Pittsburgh; the Exclusivity Agreement, that provides
      Wheeling-Pittsburgh exclusive marketing rights in North America for CSN
      products; and the Technology Sharing Agreement;






o     CSN will increase the value of the depositary "B" share to $32 from $30,
      which CSN will be required to redeem in four years;

o     CSN will reduce the Company's Convertible Debt to $175 million; and

o     CSN would seek to commit the Company to a rights offering one year
      after-closing of the merger so that non-CSN shareholders would have the
      option to purchase up to 4.6 million shares (equal to half of shares
      underlying Convertible Debt) at the Convertible Debt strike price

                  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 DEPOSITORY "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 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.

                                       2




                  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 are to 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.

Board of Directors
Wheeling-Pittsburgh Corporation
1134 Market Street
Wheeling, West Virginia  26003

Members of the Board:

                  We want to express our continuing enthusiasm for creating a
new Wheeling-Pittsburgh Corporation that will be financially stronger, and
strategically better positioned. We remain committed to this transaction which
we believe not only revitalizes Wheeling-Pittsburgh Corporation ("WPC") but also
delivers value and growth for its stockholders.



                                       3


                  We have met with many of WPC's stockholders during the past
few weeks and understand that they have differing interests and investment
objectives. In order to better address these varying interests, we have enhanced
our proposal of November 4, 2006 and hereby submit this revised proposal with
respect to the consideration payable to the stockholders of WPC in the merger
contemplated by the Agreement and Plan of Merger, dated as of October 24, 2005
(the "Merger Agreement"), by and among Companhia Siderurgica Nacional ("CSN"),
CSN Holdings Corp., CSN Acquisition Corp. and WPC. The terms of our revised
proposal are set forth in that attached non-binding term sheet.

                  Our revised proposal offers WPC stockholders:

                  o     the right to receive $32 per share from CSN in 4 years

                  o     the opportunity to invest in the future of the company
                        through a rights offering a year after the merger at $19
                        per share

                  o     a company with a stronger balance sheet with CSN's cash
                        capital contribution of $50 million as part of the
                        merger

                  We believe that our revised proposal demonstrates CSN's
commitment to WPC, a commitment that can only benefit all of WPC's stockholders
and employees in the long term as compared to the precarious financial future
that would result from any combination with Esmark.

                  Our proposal is subject to negotiation and execution of
definitive agreements. We are prepared to meet with you and your advisors to
negotiate and finalize documentation immediately upon acceptance of our proposal
by WPC's Board of Directors.



                                              Very truly yours,

                                              COMPANHIA SIDERURGICA NACIONAL

NON-BINDING TERM SHEET

ENHANCED CASH ELECTIVE STRUCTURE

CURRENT MERGER AGREEMENT

         On October 24, 2006, Companhia Siderurgica Nacional ("CSN"), CSN
Holdings Corp. ("CSN Holdings"), an indirect, wholly owned subsidiary of CSN,
CSN Acquisition Corp. ("Merger Sub"), a wholly owned subsidiary of CSN Holdings,
and Wheeling-Pittsburgh Corporation ("WPC") entered into an Agreement and Plan
of Merger (the "Merger Agreement"). The Merger Agreement provides for the merger
of WPC with and into Merger Sub (the "Merger"), with WPC stockholders receiving
50.5% of the outstanding Common Stock of CSN Holdings and CSN owning the
remaining 49.5% of outstanding Common Stock of CSN Holdings. CSN Holdings will
be renamed Wheeling-Pittsburgh Corporation ("New WPC") upon the consummation of
the Merger. The Merger Agreement also contemplates that at the closing of the
Merger, CSN will lend $225 million in cash in exchange for the issuance by New
WPC and certain of its subsidiaries of a convertible debt security (the
"Convertible Notes") that would be convertible into shares of Common Stock of


                                       4




New WPC within three years, provided that such additional ownership of equity is
not prohibited under the terms of the collective bargaining agreement (the
"CBA") then in place between New WPC and the United Steelworkers. Upon
conversion of the Convertible Note, CSN's ownership of the outstanding stock of
New WPC (the "New WPC Common Stock") would increase to 64%.

ENHANCED PROPOSAL

         Under the enhanced offer, CSN will make a cash contribution to New WPC
of $50 million (the "Cash Contribution") as part of the Merger. The amount of
CSN's loan will be reduced from $225 million to $175 million in cash and the
Convertible Note upon conversion would increase CSN's ownership of New WPC
Common Stock to approximately 60.5%. Accordingly, the aggregate amount of the
Cash Contribution and the loan by CSN will remain at $225 million. These changes
would be reflected in an amendment to the Merger Agreement and a revised version
of the agreed-upon form of the Note Purchase Agreement.

         In addition, CSN proposes to provide to WPC stockholders an elective
right (i) to receive New WPC Common Stock ("A Shares") and/or (ii) to sell to
CSN a portion of the New WPC Common Stock to be received in the Merger in
exchange for $32 per share, in cash, payable four years following the Merger
(the "B Shares"). Furthermore, New WPC will commit to have a rights offering
(the "Rights Offering") one year following the closing of the Merger Agreement.
Under the Rights Offering, holders of A Shares, other than CSN, will have the
option to purchase their pro-rata portion of 4,600,000 additional A Shares at a
price of approximately $19 per share. The participants in the Rights Offering
will also have the option to purchase on a pro-rata basis the unsubscribed
additional A Shares. The proceeds from the Rights Offering would be applied to
reduce the amount of indebtedness outstanding under the Convertible Note. If the
Rights Offering is fully subscribed, the net proceeds would reduce the principal
amount of the Convertible Note by approximately $87.5 million, which upon
conversion would reduce CSN's interest to its original 49.5% level.

         The details of the cash elective structure with respect to the B Shares
are set forth below, which would be reflected in an amendment to the Merger
Agreement. Certain changes would also be made to the agreed-upon form of
Stockholders' Agreement and Registration Rights Agreement to be entered into by
CSN and New WPC at the closing of the Merger, as described below. The details of
the Rights Offering are also set forth below.

-------------------------------- -----------------------------------------------

                                 merge with and into Merger Sub, with WPC
                                 stockholders receiving 50.5% of the
                                 outstanding Common Stock of New WPC and CSN
                                 owning the remaining 49.5%.

-------------------------------- -----------------------------------------------
ELECTION BY WPC STOCKHOLDERS     In the Merger, WPC stockholders can elect (the
TO RECEIVE CASH IN THE FUTURE    "Call Election") at the time of the Merger to
                                 have the shares of New WPC Common Stock they
                                 receive in the Merger be subject to a mandatory
                                 purchase by CSN (the "Call") for $32 per share
                                 (the "Call Price") on the 4th anniversary of
                                 the Merger (the "Call Date"), provided that the
                                 aggregate number of shares of New WPC Common
                                 Stock subject to the Call will not exceed 50%
                                 of the total number of shares of New WPC Common
                                 Stock issued to WPC stockholders in the Merger,
                                 provided, further, that the aggregate value of
                                 the Call does not exceed 60% of the total value
                                 of the consideration issued to WPC stockholders
                                 in the Merger.(1) To the extent that WPC
                                 stockholders exercise the Call Election in
                                 excess of the foregoing 50% limitation, it
                                 would be subject to pro-ration.

____________________
(1)   It is anticipated that this will be based on the value on the day before
the signing of the amendment to the Merger Agreement and this assumes that there
is no other non-stock consideration in connection with the Merger for U.S.
federal income tax purposes.

ABOUT COMPANHIA SIDERURGICA NACIONAL

CSN is a leading global steel producer with operations in Latin America, North
America, and Europe. CSN is a fully integrated steel producer, the largest

iron ore, 5.6 million tons of crude steel, 5.1 million tons of rolled products
and 2.9 million tons of coated steel capacity.

CSN's process is based on the integrated steelworks concept that uses its own

integrated steelworks concept allows CSN to be one of the most cost competitive
steel producers in the world.

subsidiary CSN LLC (formerly known as Heartland Steel) located at Terre Haute,
Indiana. CSN LLC has an annual production capacity of 1 million tons of
cold-rolled, galvanized and hot rolled products.
