      entirety and as shall read as follows:

                  (i)   Payments on Receivables, Accounts. The Seller will, and
            will cause each Originator to at all times instruct its Obligors to
            deliver payments on the Receivables to a Lock-Box Account. If any
            such payments or other Collections are received by the Seller or an
            Originator, it shall hold such payments in trust for the benefit of
            the Agent and the Purchasers and promptly (but in any event within
            two Business Days after receipt) remit such funds into a Lock-Box
            Account. The Seller will cause each Lock-Box Bank to comply with the
            terms of each applicable Lock-Box Letter. The Seller will not permit
            the funds of any Affiliate to be deposited into any Lock-Box
            Account. If such funds are nevertheless deposited into any Lock-Box
            Account, the Seller will promptly identify such funds for
            segregation. The Seller will not, and will not permit any Collection
            Agent or other Person to, commingle Collections or other funds to
            which the Agent or any Purchaser is entitled with any other funds.
            The Seller shall only add, and shall only permit an Originator to
            add, a Lock-Box Bank, Lock-Box, or Lock-Box Account to those listed
            on Exhibit F if the Agent has received notice of such addition, a
            copy of any new Lock-Box Agreement and an executed and acknowledged
            copy of a Lock-Box Letter substantially in the form of Exhibit F
            (with such changes as are acceptable to the Agent) from any new
            Lock-Box Bank. The Seller shall only terminate a Lock-Box Bank or
            Lock-Box, or close a Lock-Box Account, upon 30 days advance notice
            to the Agent.

      Section 2. To induce the Agent and the Purchasers to enter into this
Amendment, the Seller and Initial Collection Agent represent and warrant to the
Agent and the 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 Initial 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 Initial Collection Agent,
enforceable against the Seller and the Initial 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

Agent of this Amendment or the performance by the Seller or the Initial
Collection Agent of the Sale Agreement, as amended by this Amendment, or any
other Transaction Document to which they are a party.

      Section 3. 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 4. The Seller shall deliver to the Agent within 30 days of this
Amendment executed Lock-Box Letters such that all Collections on Receivables
will be delivered to Lock-Boxes and Lock-Box Accounts for which the relevant
Lock-Box Bank shall have executed and delivered a Lock-Box Letter. Failure to
comply with this covenant shall be a Termination Event.

      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 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.

and delivered by their duly authorized officers as of the date first above
written.
