Holders of shares of 6.50% Preferred Stock tendered and accepted in the exchange offers will not be paid accrued dividends upon completion of the exchange offers. Rather, all holders of 6.50% Preferred Stock as of December 3, 2001 will receive payment on December 31, 2001 in the amount of the full quarterly dividend payable on the 6.50% Preferred Stock for the fourth quarter of 2001. The exchange offers are subject to the conditions described in the Prospectus, including the minimum condition that at least $150 million principal amount of SQUIDS, in the aggregate, are issued in the exchange offers. United States Steel will accept up to a maximum face amount of (i) $77 million of 6.50% Preferred Stock, (ii) $127 million of 6.75% QUIPS and (iii) $161 million of 8.75% MIPS in the exchange offers. If United States Steel receives tenders for more than the face amount of any series of Outstanding Securities than are set forth above, it will prorate the number of validly tendered Outstanding Securities in such series that it will exchange from each tendering holder. United States Steel is making the exchange offers in connection with a reorganization of USX, pursuant to which USX will distribute all of the equity securities of United States Steel Corporation to the holders of USX's U. S. Steel Group common stock (the "Separation"). Following the Separation, United States Steel will be an independent, publicly owned company and will no longer be a subsidiary of USX. As part of the Separation, which is expected to be completed on or about December 31, 2001, United States Steel LLC will convert into United States Steel Corporation, a Delaware corporation, and USX will change its name to Marathon Oil Corporation. The Separation is subject to the satisfaction or waiver of a number of conditions. The issuance of the SQUIDS is not subject to completion of the Separation. All outstanding 8.75% MIPS will be redeemed on December 31, 2001 for a cash payment of $25 plus accrued but unpaid dividends. If the Separation occurs, the then outstanding 6.50% Preferred Stock will be converted into the right to receive, in cash, $50 per share plus accrued but unpaid dividends and the then outstanding 6.75% QUIPS will be redeemed for a cash payment of $50 plus accrued but unpaid distributions. Until the completion of the Separation, USX will fully and unconditionally guarantee the SQUIDS. Following the Separation, USX will no longer guarantee the SQUIDS and the sole obligor of the SQUIDS will be United States Steel Corporation which, after the Separation, will have a substantial amount of indebtedness and other obligations and will have a credit rating below "investment grade," which will be lower than the current credit ratings of USX. The SQUIDS -- The SQUIDS will mature on December 31, 2031. Interest on the SQUIDS will begin to accrue on the Exchange Date (as defined in the Prospectus) and will be payable quarterly on each March 31, June 30, September 30 and December 31, commencing March 31, 2002. The SQUIDS will be redeemable at the option of United States Steel, in whole or in part, on or after December 31, 2006 at 100% of the principal amount redeemed together with accrued but unpaid interest to the redemption date. If the USX board of directors determines not to proceed with the Separation, United States Steel will have the option to redeem the SQUIDS, in whole or in part, on or prior to December 31, 2002, at 100% of the principal amount redeemed, together with accrued but unpaid interest through the redemption date. Ownership of the SQUIDS will be recorded in book-entry form on the Exchange Date, and will not be represented by physical certificates.
