                  the Servicer shall designate a back-up servicer acceptable to
                  the Collateral Agent in its sole discretion (the "Back-up

                  into a back-up servicing agreement on or before January 31,

                  SECTION 4. Blended Advance Rate. The Company has determined a
Blended Advance Rate for the November 2001 Funding that has been based in part
on assumptions with respect to collections received on the Loans related to such
Funding (the "November Blended Advance Rate"). The Debtor and/or the Servicer
shall provide, on or prior to November 12, 2001, confirmation as to the
correctness of such assumptions to the Company and if upon receipt thereof the
Company determines that the November Blended Advance Rate was higher than it
would otherwise have been had such information been available to the Company
prior to the November 2001 Funding, the Company shall have the right to apply a
revised November Blended Advance Rate retroactive to November 2, 2001, at which
point the Debtor shall, on or prior to November 16, 2001, either (i) pay to the
Company such amount as is necessary to reduce the Net Investment related to the
November 2001 Funding (the "November Net Investment") such that the November Net
Investment will not be greater than the product of (x) the applicable Aggregate
Outstanding Eligible Loan Balance minus the applicable Excluded Loan Balance and
(y) the revised November Blended Advance Rate, or (ii) provide additional Loans
and related Contracts as collateral for the November 2001 Funding such that the
November Net Investment will not be greater than the product of (x) the
applicable Aggregate Outstanding Eligible Loan Balance (including the additional
Loans and related Contracts added pursuant hereto) minus the applicable Excluded
Loan





                                       5

Debtor to take one of the actions provided for in clause (i) or (ii) above in
the time required shall constitute a Termination Event under the Security
Agreement.

shall utilize and apply all funds in the Collection Account that relate to the
Funding that occurred on March 12, 2001 (the "March 2001 Funding") on behalf of
the Debtor towards payment of the amounts required to be paid to the Company in
connection with the Release Agreement dated as of even date herewith among the

the Funding that occurred on March 12, 2001 as identified on Exhibit A hereto in
addition to new Loans and related property as set forth in Amendment No. 6 to
the Contribution Agreement dated as of even date herewith (collectively, the
"November Funding Collateral"), and all references to the Net Investment with
respect to the November 2001 Funding shall refer to the Net Investment related
to the November Funding Collateral.

                  SECTION 7. Representations and Warranties. The Debtor hereby
makes to the Collateral Agent, the Company and the Bank Investors, on and as of
the date hereof, all of the representations and warranties set forth in Sections
3.1 and 3.2 of the Security Agreement, except that to the extent that any of
such representations and warranties expressly relate to an earlier date, such
representations and warranties shall be true and correct as of such earlier
date.

                  SECTION 8. Effectiveness. This Amendment shall become
effective when it has been signed by the parties hereto.

                  SECTION 9. Costs and Expenses. The Debtor shall pay all of the
Company's, the Bank Investors' and the Collateral Agent's cost and expenses
(including out of pocket expenses and reasonable attorneys fees and

separate 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
instrument. Any provisions of this Amendment which are prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

                  SECTION 12. Captions. The captions in this Amendment are for
convenience of reference only and shall not define or limit any of the terms or
provisions hereof.

                  SECTION 13. Ratification. Except as expressly affected by the
provisions hereof, the Security Agreement as amended shall remain in full force
and effect in accordance with its terms and ratified and confirmed by the
parties hereto. On and after the date hereof, each reference in the Security
Agreement to "this Agreement", "hereunder", "herein" or words of like import
shall mean and be a reference to the Security Agreement as amended by this
Amendment.
