such analysis and decision independently and without reliance on the
Administrative Agent or any other Lender, and (vii) attached as Schedule 1 to
this Assumption and Acceptance is any documentation required to be delivered by
the Added Lender with respect to its tax status pursuant to the terms of the

be performed by it as a Lender.
     3. The Borrower hereby represents and warrants that as of the date hereof
and as of the Effective Date, (a) all representations and warranties of the
Borrower contained in Article VII of the Credit Agreement shall be true and
