                  Maturity Date and on the date of any mandatory repayment) the
                  Support Party shall, at the option of the Administrative Agent
                  and from time to time as directed by it, either (x) purchase

                  (y) purchase so much of the right, title and interest of the
                  Lenders in and to their respective Commitments and Revolving

            the Borrower to the Support Party in accordance with clause
            (a)(i)(y) of this Section or Revolving Credit Exposures purchased in
            accordance with clause (a)(ii)(y) of this Section shall, in each
            case, be Subordinated to the rights of the Lenders in accordance
            with Section 2.8 hereof.

            the parties hereunder to cause the purchases referred to in Sections
            2.1(a)(i) and 2.1(a)(ii)(x) in order to provide the Borrower with
            sufficient funds to repay the Revolving Credit Exposures as and when
            due (together with accrued interest thereon and fees and other
            obligations of the Borrower accrued under the Credit Agreement) and
            restore the ratio under Section 6.11 of the Credit Agreement to the
            required level, as the case may be, and the Support Party hereby
            agrees to cause the Borrower to apply the proceeds thereof to repay
            the Revolving Credit Exposures, and such other amounts due and
            payable, immediately upon receipt of such proceeds.

            falls within Category 2 (as used in the defined term "Applicable
            Margin") as of the end of any fiscal quarter, the Support Party
            hereby agrees to maintain at all times thereafter aggregate
            unutilized commitments under its credit facilities (not including
            the Credit Agreement) in an amount equal to (x) the Revolving

rights with respect to the foregoing, and has obtained assignments of all leases
and other rights of whatever nature, necessary for the present conduct of its
business, without any known conflict with the rights of others which, or the
failure to obtain which, as the case may be, would result in a Material Adverse

      default in any manner under any provision of any indenture or other
      agreement or instrument evidencing Indebtedness, or any other material
      agreement or instrument to which it is a party or by which it or any of
      its properties or assets are or may be bound, where such default could
      result in a Material Adverse Effect.

      SECTION 3.16. Borrower's Business. The Support Party is familiar with
Borrower's financial condition and business operations and has done all
