shall promptly notify the other parties hereto of:

               (a) any notice or other communication from any Person, including

consummation of any of the Transactions or otherwise asserting any objection to

LTV Steel and LTV-W and its Affiliates will hold, and will cause their
respective officers, directors, employees, accountants, counsel, consultants,
advisors and agents to hold, in confidence, unless compelled to disclose by
judicial or administrative process or by other requirements of law, all
confidential documents and information concerning the Partnership except to the
extent that such information can be shown to have been (i) in the public domain
through no fault of LTV Steel or LTV-W, as the case may be, or their respective
Affiliates or (ii) later lawfully acquired on a nonconfidential basis by LTV
Steel or LTV-W, as the case may be, or their respective Affiliates. The
obligation of LTV Steel and LTV-W and their respective Affiliates to hold any
such information in confidence shall be satisfied if they exercise the same

                                        8

in Article III hereof shall expire upon the completion of the Closing; provided,
