Filed by Companhia Siderurgica Nacional under its name translated into English: National Steel Company pursuant to Rule 425 under the Securities Act of 1933 and deemed filed pursuant to Rule 14a-12 under the Securities Exchange Act of 1934 Subject Company: Wheeling-Pittsburgh Corporation Commission File No.: 000-50300 On November 14, 2006, Companhia Siderurgica Nacional issued the following press release concerning the proposed strategic alliance between Companhia Siderurgica Nacional and Wheeling-Pittsburgh Corporation. The following press release contains forward looking statements as discussed more fully below. 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. The CSN Letter and term sheet of the enhanced offer follow: COMPANHIA SIDERURGICA NACIONAL Av. Brigadeiro Faria Lima, 3400 - 20(degree) Andar 04538-132 - Itaim Bibi - Sao Paulo - SP - Brasil November 13, 2006 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 /s/ Benjamin Steinbruch --------------------------- Name: Benjamin Steinbruch Title: CEO and Chairman 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. -------------------------------- ----------------------------------------------- MERGER STRUCTURE Existing Merger structure, in which WPC will 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. 5 -------------------------------- ----------------------------------------------- DEPOSITARY SHARES All shares of New WPC Common Stock which are subject to the Call will be deposited with a Depositary (the "Deposited Common Stock") immediately upon issuance in the Merger and the WPC stockholders who have made the Call Election will receive depositary shares (the "Depositary Shares") representing their interest in the Deposited Common Stock and CSN's Call obligation.
