B.       AMENDMENTS

         (a)      Section 6.2. A new Section 6.2(x) is hereby added to the
Participation Agreement to read as follows:

                  (x)      The Credit Parties do not intend to treat the Loans
         and/or Holder Advances and related transactions as being a "reportable
         transaction" (within the meaning of Treasury Regulation Section
         1.6011-4). In the event any Credit Party determines to take any action
         inconsistent with such intention, it will promptly notify the Agent
         thereof. If a Credit Party so notifies the Agent, the Credit Parties
         acknowledge that one or more of the Financing Parties may treat its
         Loans and/or Holder Advances as part of a transaction that is subject
         to Treasury Regulation Section 301.6112-1, and such Financing Party or
         Financing Parties, as applicable, will maintain the lists and other
         records required by such Treasury Regulation. Promptly after a Credit
         Party has notified the Agent of any intention by such Credit Party to
         treat the Loans and/or Holder Advances and related transactions as
         being a "reportable transaction" (within the meaning of Treasury
         Regulation Section 1.6011-4), the Credit Parties shall deliver to the
         Agent a duly completed copy of IRS Form 8886 or any successor form.

         (b)      Section 8.3A. Section 8.3A(h)(i) of the Participation
Agreement is hereby amended to read as follows:

                  (h)      Financial Covenants.

                           (i)      Leverage Ratio. The Leverage Ratio, as of
                  the last day of each fiscal quarter of the Lessee, shall be
                  less than or equal to:

                                    (A)      From and including December 31,
                                    2001 to and including March 31, 2003, 2.50
                                    to 1.0;

                                    (B)      From and including April 1, 2003 to
                                    and including June 30, 2003, 3.00 to 1.0;

                                    (C)      From and including July 1, 2003 to
                                    and including September 30, 2003, 2.25 to
                                    1.0; and

                                    (D)      From October 1, 2003 and
                                    thereafter, 2.0 to 1.0.

         (c)      Section 12.13. The following paragraph is hereby added to the
end of Section 12.13 to read as follows:

                  Notwithstanding anything herein to the contrary, "information"
         shall not include, and the Agent and each Financing Party may disclose
         without limitation of any kind, any information with respect to the
         "tax treatment" and "tax structure" (in each case, within the meaning
         of Treasury Regulation Section 1.6011-4) of the transactions
         contemplated hereby and all materials of any kind (including opinions
         or other tax analyses) that are provided to the Agent or such Financing
         Party relating to such tax treatment and tax structure; provided that
         with respect to any document or similar item that in either case
         contains information concerning the tax treatment or tax structure of
         the transaction as well as other information, this sentence shall only
         apply to such portions of the document or similar item that relate to
         the tax treatment or tax structure of the Loans, Holder Advances and
         transactions contemplated hereby.
