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

                               ISS ISSUES REPORT,
             DECLARES CSN PROPOSAL FOR WHEELING-PITTSBURGH SUPERIOR

                         CSN Merger Agreement Dependent
             on Re-Election of Wheeling-Pittsburgh Director Nominees

SAO PAOLO, BRAZIL, Nov. 15 -- Companhia Siderurgica Nacional (CSN) (NYSE: SID)
today announced that Institutional Shareholder Services (ISS), one of the
leading providers of proxy advisory services, has issued a new report in which
it declares CSN's enhanced proposal of November 14, 2006 to shareholders of
Wheeling-Pittsburgh Corporation (NASDAQ:WPSC) a "better alternative."

Marcos Lutz, Vice President for Infrastructure and Energy, CSN, said, "We
understand that ISS's stated policy is not to change formal recommendations so
close to a meeting date, and so we are extremely pleased with ISS's statement
that it deems our proposal 'a better alternative'. ISS evidently has seen
through the barrage of rhetoric, and it recognizes that our enhanced proposal
will create the most value for Wheeling--Pittsburgh shareholders. We hope all
shareholders will now re-elect Wheeling-Pittsburgh's director nominees to the
Board of Directors at its annual meeting of shareholders tomorrow."

In its updated report, ISS concludes that the revised CSN proposal addresses
most of its concerns with the initial CSN offer. Specifically, ISS said that the
advantages that the CSN offer provides include:

      o     "Higher underlying equity valuation: The additional $50 million in
            cash injection should improve WP's liquidity situation. Moreover, as
            it does not increase CSN's equity ownership in the company, we
            consider it to have the same effect as increasing the underlying
            offer price for WP's shares.


      o     Increase in redemption price for B shares: Assuming, 7-8 percent
            discount rate (these rates have been used by Esmark in their
            presentation), the present value of the revised $32/share redemption
            price for B shares comes to $23.5-24.4 per share. The present value
            compares favorably against the $20/share share buy-back that Esmark
            has proposed. Also, the revised proposal answers our initial
            questions on B shares, by providing greater information on the
            liquidity, marketability, and depositary mechanics. The new B shares
            are expected to be listed on the NASDAQ exchange and would be held
            in a depository

      o     Reduced leverage: By reducing the amount of convertible debt to $175
            million and by injecting $50 million in new cash, the revised
            proposal increases net debt by $125 million, compared to $225
            million previously. We believe that the lower level of net debt may
            be more manageable, and does not significantly affect WP's leverage.

      o     Rights issue: The revised offer now entitles existing WP
            shareholders, who opt for A shares in the new combined company, to
            subscribe to rights issue at $19/share for up to 4.6 million shares.
            We believe that the ability to subscribe to the rights issue allows
            class A shareholders to participate in the potential upside of the
            company. More importantly, we believe that this proposal, now makes
            the CSN offer comparable to the Esmark offer in terms of
            shareholders ability to participate in the upside by subscribing to
            rights issue, at a potentially discounted price.

      o     Strong credentials of CSN designees: WP has also disclosed the
            names, experience and background of CSN designees for the new board,
            assuming the WP/CSN transaction is consummated. We believe that all
            three designees would bring relevant experience to the board. Given
            the background and experience of CSN designees, we are no longer
            concerned about the potential lack of steel experience on the
            proposed WP/CSN board."

Further, CSN noted the recent disclosure by Wheeling-Pittsburgh that the change
of control provisions of Wheeling-Pittsburgh's credit facility will be triggered
by the election of the Esmark director-nominees.

Shareholders who have questions or need assistance in voting their GOLD proxy
card for the Wheeling-Pittsburgh director-nominees should call
Wheeling-Pittsburgh's proxy solicitors, Georgeson Shareholder, toll-free at
