                           (n) The Credit Agreement is hereby amended by adding
         a new Section 8.17 thereto to read as follows:

                           8.17 JOINT AND SEVERAL OBLIGATIONS. Each Borrower
                  shall be jointly and severally liable for the

<PAGE>

                  Obligations arising in connection with Loans made to it and
                  the Obligations arising in connection with Loans made to the
                  other Borrower; PROVIDED, HOWEVER, that if it is at any time
                  determined that either Borrower is liable as a guarantor (and
                  not as a co-obligor or co-borrower) with respect to such
                  Obligations arising in connection with Loans made to the other
                  Borrower (the "Guaranteed Obligations"), each Borrower hereby
                  agrees to the terms set forth on Exhibit P hereto with respect
                  to the Guaranteed Obligations.

                  (p) The Credit Agreement is hereby amended by adding a new
         Exhibit L thereto to read as set forth on Exhibit L hereto.

                  (q) Schedule 1.01(b) to the Credit Agreement is hereby
         amended in its entirety to read as set forth on Schedule 1.01(b)
         hereto.

         3. CONSENT. Pursuant to Section 5(g) of the Residual Security
Agreement, NCCC and NCRC agreed to cause "GCFPI" and "PWRESI" (as defined
therein) to enter into intercreditor and agency agreements, in form and
substance reasonably satisfactory to the Collateral Agent, on or before May 31,
2000, concerning the Collateral Agent's security interest in certain Junior
Securitization Interests. The Borrowers have requested that the Lenders (a)
waive this requirement with respect to the Junior Securitization Interests
described on Schedule 3 to the Residual Security Agreement (but not with respect
to any future Junior Securitization Interests that may be financed by PWRESI),
and (b) extend the deadline for the delivery of such intercreditor and agency
agreement by GCFPI until June 30, 2000. Upon the date on which this Amendment
becomes effective, the Lenders hereby agree to such waiver and extension.
Nothing herein shall be deemed a waiver by the Lenders of any other term,
condition, representation or covenant applicable to the Borrowers under the Loan
Documents (including, but not limited to, the foregoing requirement of Section
5(g) of the Residual Security Agreement with respect to GCFPUI, as so extended,
or any requirement of Section 5(l) of the Residual Security Agreement, whether
PWRESI, GCFPI or any other Person provides Residual Financing) or any of the
other agreements, documents, or instruments executed and delivered in connection
therewith. The consent set forth herein shall not constitute a course of action
with respect thereto upon which the Borrowers may rely in the future, and the
Borrowers expressly waive any such claim.

         4. CONDITIONS TO EFFECTIVENESS OF THIS AMENDMENT. This Amendment shall
become effective when the Agent shall have received at least thirteen (13)
counterparts of this Amendment, duly executed by the Borrowers and the Required
Lenders, provided the following conditions are satisfied:

                  (a) Before and after giving effect to this Amendment, the
         representations and warranties of the Borrowers in Section 3 of the
         Credit Agreement, Section 5 of the Pledge and Security Agreement and
         Section 4 of the Servicing Security Agreement, of NCCC and NC Residual
         II Corporation in Section 4 of the Residual Security Agreement, and of
         NCFC in Section 15 of the Guaranty shall be true and correct as though
         made on the date hereof, except for changes that are permitted by the
         terms of the Credit Agreement.

     Each Borrower hereby agrees to the following terms with respect to Loans

performance of the Other Borrower Debt before preceding against such
Borrower; (c) agree that no release of the other Borrower or any other
guarantor or Obligor, or of any collateral, for the Other Borrower Debt,
whether by operation of law or by any act of the Agent or the Lenders (or any
of them), with or without notice to such Borrower, shall release such
Borrower; and (d) waive presentment, notice of acceptance, notice of demand,

    5.  The obligations of each Borrower for the Other Borrower Debt shall be
primary, absolute, irrevocable and unconditional, and shall remain in full
force and effect without regard to, and shall not be impaired or affected by:
(a) the genuineness, validity, regularity or enforceability of, or any
amendment or change in the Credit Agreement or the Note, or any change in or
extension of the manner, place or terms of payment of, all or any portion of
the Other Borrower Debt; (b) the taking or failure to take any action to
enforce the Credit Agreement or the Notes, or the exercise or failure to
exercise any remedy, power or privilege contained therein or available at law
or otherwise, or the waiver by the Lenders of any provisions of the Credit
Agreement or the Notes; (c) any impairment, modification, change, release or
limitation in any manner of the liability of the other Borrower or its estate
in bankruptcy, or of any remedy for the enforcement of the other Borrower's
liability, resulting from the operation of any present or future provision of
the bankruptcy laws or any other statute or regulation, or the dissolution,
bankruptcy, insolvency, or reorganization of the other Borrower; (d) the
merger or consolidation of the other Borrower, or any sale or transfer by the
other Borrower of all or part of its assets or property; (e) any claim such
Borrower may have against the other Borrower or any other Obligor, including
any claim of contribution; (f) the release, in whole or in part, of any other
guarantor (if more than one), the other Borrower or any other Obligor; (g)
any other action or circumstance which (with or without notice to or
knowledge of such Borrower) might in any manner or to any extent vary the
risks of such Borrower or otherwise constitute a legal or equitable discharge
or defense, it being understood and agreed by each Borrower that its
obligations for the Other Borrower Debt shall not be discharged except by the
full payment and performance of the Other Borrower Debt.

    6.  The Lenders shall have the right to determine how, when and what
application of payments and credits, if any, whether derived from either
Borrower or from any other source, shall be made on the Obligations and any
other indebtedness owed by either Borrower and/or any other Obligor to the
Lenders.

    7.  The obligations of each Borrower hereunder shall continue to be
effective, or be automatically reinstated, as the case may be, if at any time
the performance or the payment, as the case may be, in whole or in part, of
any of the Other Borrower Debt is rescinded or must otherwise be restored or
returned by the Lenders (or any of them) (as a preference, fraudulent
conveyance or otherwise) upon the insolvency, bankruptcy, dissolution,
liquidation or reorganization of either Borrower or any other person or upon
or as a result of the appointment of a custodian, receiver, trustee or other
officer with similar powers with respect to either Borrower or any other
Person, or any substantial part of its property, or otherwise, all as though
such payments had not been made. If an Event of Default shall at any time
have occurred and be continuing or shall exist and declaration of default or
acceleration under or with respect to the Other Borrower Debt shall at such
time be prevented by reason of the pendency against either Borrower or any
other Person of a case or proceeding under a bankruptcy or insolvency law,
each Borrower agrees that its obligations for the Other Borrower Debt shall
be deemed to have been declared in default or accelerated with the same
effect as if such obligations had been declared in default and

accelerated in accordance with their respective terms and each Borrower shall
forthwith perform or pay, as the case may be, as required hereunder in
accordance with the terms hereunder without further notice or demand.

    8.  Each Borrower hereby irrevocably waives any claim or other rights
that it may now or hereafter acquire against the other Borrower that arises
from the existence, payment, performance or enforcement of such Borrower's
obligations for the Other Borrower Debt, including any right of subrogation,
reimbursement, exoneration or indemnification, any right to participate in
any claim or remedy of the Lenders against the other Borrower or any
collateral that the Lenders now have or hereafter acquire, whether or not
such claim, remedy or right arises in equity or under contract, statute or
common law, including the right to take or receive from the other Borrower
directly or indirectly, in cash or other property or by set-off or in any
manner, payment or security on account of such claim or other rights. If any
amount shall be paid to either Borrower in violation of the preceding
sentence and the Other Borrower Debt shall not have been paid and performed
in full, such amount shall be deemed to have been paid to such Borrower for
the benefit of, and held in trust for, the Lenders and shall forthwith be
paid to the Lenders to be credited and applied to the Other Borrower Debt,
whether matured or unmatured. Notwithstanding the blanket waiver of
subrogation rights as set forth above, each Borrower hereby specifically
acknowledges that any subrogation rights which it may have against the other
Borrower or any collateral that the Lenders now have or hereafter acquire may
be destroyed by a nonjudicial foreclosure of the collateral. This may give
such Borrower a defense to a deficiency judgment against it. Such Borrower
hereby irrevocably waives such defense. Each Borrower acknowledges that it
will receive direct and indirect benefits from the arrangements contemplated
by the Agreement and the Notes and that the waivers set forth in this Section
are knowingly made in contemplation of such benefits.

    9.  No postponement or delay on the part of the Lenders (or any of them)
in the enforcement of any right with respect to the Obligations of either
Borrower, including, without limitation, the Other Borrower Debt, shall
constitute a waiver of such right and all rights of the Lenders hereunder
shall be cumulative and not alternative and shall be in addition to any other
rights granted to the Lenders in any other agreement or by law.

    10.  Any indebtedness of either Borrower now or hereafter held by the
other Borrower is hereby subordinated to the indebtedness of the Borrowers to
the Lenders, and such indebtedness of either Borrower to the other Borrower
shall, if any of the Lenders so requests, be collected, enforced and received
by the Borrower to which it is owed as trustee for the Lenders and be paid
over to the Lenders on account of the indebtedness of the other Borrower to
the Lenders.
