Agreement and the Fee Letter in certain respects as set forth herein.

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto hereby agree as follows:

         SECTION 1. Definitions. Capitalized terms used in this Amendment and
not otherwise defined herein shall have the meanings assigned thereto in the
Receivables Purchase Agreement.

         SECTION 2. Purchase Limit. Section 1.01 of the Receivables Purchase
Agreement is hereby amended by deleting the number "$210,000,000" where it
appears therein and substituting the number "$100,000,000." Notwithstanding
anything to the contrary set forth in the Receivables Purchase Agreement, Seller
hereby agrees that the Capital shall not exceed $45,000,000, and that Seller
shall have no right to request any Purchase to the extent that, after giving
effect thereto, the Capital would exceed $45,000,000.

         SECTION 3. Commitment. The definition of "Commitment" that appears in
Appendix A to the Receivables Purchase Agreement is hereby amended by deleting

"`Commitment' means (i) $42,857,142.86 with respect to Liberty Street Funding
<PAGE>
Corp. and $57,142,857.14 with respect to Blue Keel and (ii) with respect to any

Agreement and Amendment to Fee Letter, dated as of November 5, 2002."

         SECTION 4. Delinquency Ratio. Section 10.01 of the Receivables Purchase
Agreement is hereby amended by deleting the percentage "10%" where it appears in

         SECTION 5. Termination Date. The definition of "Termination Date" set
forth in Appendix A to the Receivables Purchase Agreement is hereby amended by
deleting the date set forth in clause (c) thereof and substituting therefor the
date "December 13, 2002".

         SECTION 6. Amendment to Fee Letter. The Fee Letter is hereby amended by
deleting the percentage "0.50%" where it appears in paragraph (b) thereof and
substituting therefor the percentage "0.75%".

         SECTION 7. Representations and Warranties. Each of Parent and Seller
hereby represents and warrants that, after giving effect to this Amendment, (i)
the representations and warranties contained in Article VI of the Receivables
Purchase Agreement are true and correct on and as of the date hereof and shall
be deemed to have been made on such date (except that any such representation or
warranty that is expressly stated as being made only as of a specified earlier
date shall be true and correct in all material respects as of such earlier date)
and (ii) no Liquidation Event or Unmatured Liquidation Event has occurred and is
continuing.

         SECTION 8. Miscellaneous. The Receivables Purchase Agreement and the
Fee Letter, as amended hereby, remain in full force and effect. Any reference to
the Receivables Purchase Agreement or the Fee Letter from and after the date
hereof shall be deemed to refer to the Receivables Purchase Agreement or the Fee
Letter, as the case may be, as amended hereby. This Amendment may be executed in
counterparts, each of which when so executed shall be deemed to be an original
and all of which when taken together shall constitute one and the same
agreement. This Amendment shall be governed by, and construed in accordance
with, the laws of the State of New York. Seller, on demand, shall pay, or
reimburse the Administrator for, all of the costs and expenses, including legal
fees and disbursements, incurred by the Administrator or any Purchaser in
connection with this Amendment.
