          "Closing") shall take place at the offices of Jones Day, North Point,
          901 Lakeside Avenue, Cleveland, OH 44114, at 10:00 a.m. eastern time

          shall remain subject to the subrogation waiver by Sellers of the
          conditions contained in Section 7.1 and Buyers' and ISG's obligations
          shall be subject to the satisfaction or waiver of the conditions
          contained in Section 7.2; provided, further, that the Closing may be
          held at any other time or place, or on any other date (the date on
          which the Closing actually occurs, the "Closing Date") by consent of
          all of Sellers, Buyer and ISG."

     2.   Section 15 of Amendment No. 2 is hereby deleted (with the effect that
Section 5.1(i) of the Agreement and the definition of "Avoidance Action" are
restored in their original form.

     3.   Section 5.8 of the Agreement is hereby amended and restated in its
entirety as follows:

          "5.8 Timing and Coordination of Closing.

          (a) Notwithstanding anything to the contrary in Section 3.1, Buyer and
          Sellers shall prepare to, and shall use best efforts to, consummate
          the transactions contemplated by this Agreement on the terms set forth
          herein on, or as promptly as practicable after, May 17, 2004. Best
          efforts shall not require any party to make any effort to or spend any
          money to settle any dispute with any creditor of Sellers.

          (b) Sellers acknowledge that they have designated Buyer as the
          Successful Bidder under the Bid Procedures Order. If at any time on or
          prior to May 17, 2004 (the "Designated Date") (i) the Sale Order
          approving the sale to Buyer as the Successful Bidder has been entered,
          (ii) the conditions contained in Sections 7.2(a), 7.2(b), 7.2(d),
          7.2(f), 7.2(j), 7.2(n) and 7.2(p) are satisfied, and (iii) Sellers
          notify ISG and Buyer of the occurrence of the satisfaction of the
          conditions described in clauses (i) and (ii) of this Section 5.8(b),
          then ISG and Buyer shall waive the conditions contained in



                                       2

          Sections 7.2(c), 7.2(g), 7.2(h) and 7.2(c) in connection with any
          Closing on the Designated Date and shall use their respective best
          efforts to effect the Closing on the terms set forth herein on the
          Designated Date (provided that the conditions listed in clause (ii)
          above remain satisfied on the Closing Date)."

     4. Section 8.1(h) is hereby amended by the addition of the following
language, immediately after the words "chapter 7 case" at the end thereof:


          "or (iv) the Closing has not occurred on May 17, 2004 (or such later
          date as Buyer and Seller may hereafter select in accordance with
          Section 11.9) as a result of the non-satisfaction or non-waiver of one
          or more of the conditions contained in Section 7.1, and the
          non-satisfaction of such condition or conditions does not result
          principally from the inaccuracy of any representation or warranty of
          Buyer or ISG, or the breach of any material covenant by Buyer or ISG,
          in either case first occurring after May 5, 2004."

     5. Article 12 of the Agreement is hereby amended by the addition of the
following definitions:

          "Noteholders" means, collectively, the holders of WSC's 10% Senior
          Secured Notes due 2008 and Secured Pollution Control Revenue Refunding
          Bonds Series 2002, J.P. Morgan Trust Company, National Association and
          the Informal Committee of Secured Noteholders.

     6. The Agreement remains in full force and effect except as and to the
extent modified by this Amendment.

     7. This Amendment shall be construed, performed and enforced in accordance
with, and governed by, the laws of the State of New York (without giving effect
to the principles of conflicts of laws thereof), except to the extent that the
laws of such State are superseded by the Bankruptcy Code or other applicable
federal law.

     8. This Amendment may be executed in counterparts, each of which shall be
deemed an original, but all of which shall constitute the same agreement.
