ASSOCIATED PRESS NEWSWIRES -------------------------- CSN SUGGESTS "CASH ALTERNATIVE" TO WHEELING-PITT DEAL By VICKI SMITH, Associated Press Writer September 14, 2006 MORGANTOWN, W.Va. (AP) - A Brazilian steelmaker eyeing a merger with Wheeling Pittsburgh Steel Corp. said Thursday it's willing to offer shareholders cash to supplement its bid, but it can't do so unless the United Steelworkers union agrees. Companhia Siderurgica Nacional also told The Associated Press that the process shareholders will use to vote on the proposed merger will be changed, separating the mid-November board of directors vote from the vote on the partnership. Wheeling-Pitt, an independent steelmaker that has survived two bankruptcies, wants to merge with CSN, while its union supports a takeover attempt by Esmark Inc., an Illinois-based steel service center. Under its contract, the USW has the right to reject any deal that changes controlling interest in the company. But under terms of the carefully crafted merger, CSN would take 49.5 percent ownership of the new company, while Wheeling-Pitt shareholders would control the other 50.5 percent. Dave McCall, District 1 director for the USW, said CSN had not come to him with either of its ideas as of late Thursday. The current structuring of the CSN deal calls for a $225 million, 9 percent interest loan that would convert to 11.8 million shares in the new company. CSN says that would generate much-needed cash for upgrades, including plans to expand Wheeling-Pitt's hot strip mill capacity to 4 million tons and to add a second galvanizing line at CSN's processing plant in Terre Haute, Ind. The current deal does not offer extra cash to existing shareholders, who would simply get the combined value of the new company and realize the financial benefits over time. In a joint telephone interview, however, CSN executive Marcos Lutz and Greenhill & Co. investment banker John Liu said they would sweeten the merger for shareholders if the union were to consent. "Even now, we could put money on the table and say, 'If you prefer, you can sell the stock,'" said Lutz, CSN's managing director for infrastructure and energy. Added Liu, "The right choice for shareholders, if we could provide it, would be to provide an alternative -- cash, stock or a mix. If we could." McCall said the appeal of the so-called cash alternative would depend on what CSN was willing to pay. "If the cash is a multiple of the current stock value, that's one thing," he said. "If it's not, that's something else." Wheeling-Pitt shares closed up 1.7 percent at $16.97 on the Nasdaq Stock Exchange Thursday. CSN and Wheeling-Pitt say their merger would make the Ohio Valley steelmaker's future more secure by ensuring a long-term supply of slab steel from CSN's Brazilian mills. But McCall and Esmark contend what's good for CSN -- a guaranteed buyer of slab -- is not necessarily good for Wheeling-Pitt and its workers. Wheeling-Pitt's plants employ 3,100 people in Ohio, Pennsylvania and West Virginia. "Their deal is not beneficial for us or our retirees," McCall said. Rather, he said, it piles more debt onto a company that hardly needs it and sets the stage for an eventual takeover by CSN. Wheeling-Pitt had $268.2 million in long-term debt on its balance sheet at the end of the second quarter, compared with $284.1 million at the end of the same period last year. The showdown for control culminates Nov. 17 at the annual meeting in Pittsburgh, where shareholders will vote on the two proposals and two new boards of directors. But CSN and Wheeling-Pitt have altered their strategy for that meeting, creating a two-step process for approval of the merger. "CSN is not going to try to tie the transaction to the board slate," Liu said. If Wheeling-Pitt's preferred board of directors is approved, a second vote on the merger would be held at a later date. "Therefore," Liu said, "if you go with Esmark, you're tying yourself to Esmark and their management." McCall said he was unaware of the two-vote plan and wasn't sure what strategic advantage it gives CSN. "They're about Wall Street or whatever street it is in Sao Paolo," he said. "We're about making sure we have long-term security for our employees and retirees." 2 # # # The information contained in the foregoing articles, other than historical information, consists of forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act.
