<PAGE>   6

all of which the Agent and the Lenders hereby expressly reserve. The Borrower,
each other Credit Party, the Lenders and the Agent agree and acknowledge that
this Agreement constitutes a "Loan Document" under and as defined in the Credit
Agreement.

                  (b) Without limiting the provisions of the immediately
preceding subparagraph, the Borrower confirms its understanding that all
Overadvances heretofore and hereafter made by the Agent to or for the benefit of
the Borrower were and continue to be discretionary in nature, and payable on

amounts thereunder, all such amounts shall constitute Obligations secured by
Liens in favor of the Agent, for the benefit of GE Capital, in all of the
Collateral pursuant to the Collateral Documents. At such time as GE Capital no

owed loans or other amounts thereunder, such loans and other amounts (if still
outstanding) shall no longer constitute Obligations or be secured by the
Collateral. In any event, at no time shall any loans or other amounts owing to
the Pegasus Funds be secured by any Collateral or other property of the Credit
Parties, as provided by Section 6.7 of the Credit Agreement.

                  7. Reaffirmation. Each of the Borrower and the other Credit
Parties hereby (a) ratifies and reaffirms all of its payment and performance
obligations, contingent or otherwise, under each Loan Document to which it is a
party, (b) agrees and acknowledges that such ratification and reaffirmation is
not a condition to the continued effectiveness of such Loan Documents and (c)
agrees that neither such ratification and reaffirmation, nor the Agent's and the
Lenders' solicitation of such ratification and reaffirmation, constitutes a
course of dealing giving rise to any obligation or condition requiring a
ratification or reaffirmation of the Borrower's or the other Credit Parties'
obligations under the Loan Documents with respect to any subsequent
modifications to the Credit Agreement or other Loan Documents.

                  8. Governing Law. This Agreement shall be governed by and
construed in accordance with the laws and decisions of the State of Illinois
(including S.H.A. 735 ILCS 105/5-1, et. seq., but without giving effect to any
other conflicts of law provisions).
