received, in form and substance satisfactory to the Agent, all documents and
certificates as the Agent may be reasonably request and all other matters
incident to the execution hereof are satisfactory to the Agent.

      Section 3. To induce the Agent and the Related Committed Purchasers to
enter into this Amendment, the Seller and Collection Agent represent and warrant
to the Agent and the Related Committed Purchasers that: (a) the representations
and warranties contained in the Transaction Documents, are true and correct in
all material respects as of the date hereof with the same effect as though made
on the date hereof (it being understood and agreed that any representation or
warranty which by its terms is made as of a specified date shall be required to
be true and correct in all material respects only as of such specified date);
(b) no Potential Termination Event exists; (c) this Amendment has been duly
authorized by all necessary corporate proceedings and duly executed and
delivered by each of the Seller and the Collection Agent, and the Sale
Agreement, as amended by this Amendment, and each of the other Transaction
Documents are the legal, valid and binding obligations of the Seller and the
Collection Agent, enforceable against the Seller and the Collection Agent in
accordance with their respective terms, except as enforceability may be limited
by bankruptcy, insolvency or other similar laws of general application affecting
the enforcement of creditors' rights or by general principles of equity; and (d)
no consent, approval, authorization, order, registration or qualification with
any governmental authority is required for, and in the absence of which would
adversely effect, the legal and valid execution and delivery or performance by
the Seller or the Collection Agent of this Amendment or the performance by the
Seller or the Collection Agent of the Sale Agreement, as amended by this
Amendment, or any other Transaction Document to which they are a party.

      Section 4. This Amendment may be executed in any number of counterparts
and by the different parties on separate counterparts and each such counterpart
shall be deemed to be an original, but all such counterparts shall together
constitute but one and the same Amendment.

      Section 5. Except as specifically provided above, the Sale Agreement and
the other Transaction Documents shall remain in full force and effect and are
hereby ratified and confirmed in all respects. The execution, delivery, and
effectiveness of this Amendment shall not operate as a waiver of any right,
power, or remedy of any Agent or any Related Committed Purchaser under the Sale
Agreement or any of the other Transaction Documents, nor constitute a waiver or
modification of any provision of any of the other Transaction Documents. All
defined terms used herein and not defined herein shall have the same meaning
herein as in the Sale Agreement. The Seller agrees to pay on demand all costs
and expenses (including reasonable fees and expenses of counsel) of or incurred
by the Agent and each Purchaser Agent in connection with the negotiation,
preparation, execution and delivery of this Amendment.
