            cause the preparation by other appropriate persons of all such
            documents, reports, filings, instruments, certificates and opinions
            as it shall be the duty of the Issuer or the Owner Trustee to
            prepare, file or deliver pursuant to the Basic Documents, and at the
            request of the Owner Trustee shall take all appropriate action that
            it is the duty of the Issuer or the Owner Trustee to take pursuant
            to the Basic Documents. Subject to Section 5 of this Agreement, and
            in accordance with the reasonable written directions of the Owner
            Trustee, the Administrator shall administer, perform or supervise
            the performance of such other activities in connection with the
            Collateral (including the Basic Documents) as are not covered by any

            of income) to a Certificateholder as contemplated in Section 5.02(c)
            of the Trust Agreement. Any such notice shall specify the amount of
            any withholding tax required to be withheld by the Owner Trustee
            pursuant to such provision.

                  (iii) Notwithstanding anything in this Agreement or the Basic
            Documents to the contrary, the Administrator shall be responsible
            for performance of the duties of the Administrator set forth in

            each Certificateholder to prepare its federal and state income tax
            returns.

                  (iv) The Administrator shall satisfy its obligations with
            respect to clauses (ii) and (iii) above and under the Trust
            Agreement by retaining, at the expense of the Administrator, a firm
            of independent public accountants (the "Accountants") which shall
            perform the obligations of the Administrator thereunder; provided,
            however, that the Certificateholder is not the Administrator or any
            of its Affiliates.

                  In connection with paragraph (ii) above, the Accountants will
            provide, prior to December 1 of each year, a letter in form and
            substance satisfactory to the Owner Trustee as to whether any tax
            withholding is then required and, if required, the procedures to be
            followed with respect thereto to comply with the requirements of the
            Code; provided, however, that the Certificateholder is not the
            Administrator or any of its Affiliates. The Accountants shall be
            required to update the letter in each instance that any additional
            tax withholding is subsequently required or any previously required
            tax withholding shall no longer be required.

                  (v) The Administrator shall perform the duties of the
            Administrator specified in Section 10.02 of the Trust Agreement
            required to be performed in connection with the removal of the Owner
            Trustee, and any other duties expressly required to be performed by
            the Administrator under the Trust Agreement.

                  (vi) In carrying out the foregoing duties or any of its other
            obligations under this Agreement, the Administrator may enter into
            transactions with or otherwise deal with any of its Affiliates;
            provided, however, that the terms of any such transactions or
            dealings shall be in accordance with any directions received from
            the Issuer and shall be, in the Administrator's opinion, no less
            favorable to the Issuer than would be available from unaffiliated
            parties.

            (c) Non-Ministerial Matters.

                  (i) With respect to matters that in the reasonable judgment of
            the Administrator are non-ministerial, the Administrator shall not
            take any action unless within a reasonable time before the taking of
            such action (x) the Administrator shall have notified the Owner
            Trustee of the proposed action and the Owner Trustee shall have
            consented thereto or provided an alternative direction, and (y) all
            approvals required under the Basic Documents shall have been
            obtained. For the purpose of the preceding sentence,
            "non-ministerial matters" shall include, without limitation:

                        (A) the amendment of the Indenture or execution of any
                  supplement to the Indenture;

<PAGE>
                        (B) the initiation of any claim or lawsuit by the Issuer
                  and the compromise of any action, claim or lawsuit brought by
                  or against the Issuer (other than in connection with the
                  collection of the Receivables);

                        (C) the amendment, change or modification of any of the
                  Basic Documents;

                        (D) the appointment of successor Note Registrars or
                  successor Paying Agents pursuant to the Indenture or the
                  appointment of successor Administrators, or the consent to the
                  assignment by the Note Registrar, Paying Agent or Indenture
                  Trustee of its obligations, in each case under the Indenture;
                  and

                        (E) the removal of the Indenture Trustee.

                  (ii) Notwithstanding anything to the contrary in this
            Agreement, the Administrator shall not be obligated to, and shall
            not (x) make any payments to the Noteholders under the Basic
            Documents, (y) sell the Trust Estate pursuant to Section 5.04 of the
            Indenture or (z) take any other action that the Issuer directs the
            Administrator not to take on its behalf.

      2. RECORDS. The Administrator shall maintain appropriate books of account
and records relating to services performed hereunder, which books of account and
records shall be accessible for inspection by the Issuer, the Owner Trustee and
the Indenture Trustee at any time during normal business hours upon reasonable
advance written notice.

      3. COMPENSATION. As compensation for the performance of the
Administrator's obligations under this Agreement and as reimbursement for its
expenses related thereto, the Administrator shall be entitled to a fee of
$200.00 per month which shall be solely an obligation of the Servicer.

      4. ADDITIONAL INFORMATION TO BE FURNISHED TO THE ISSUER. The Administrator
shall furnish to the Issuer from time to time such additional information
regarding the Collateral as the Issuer shall reasonably request.

      5. INDEPENDENCE OF THE ADMINISTRATOR. For all purposes of this Agreement,
the Administrator shall be an independent contractor and shall not be subject to
the supervision of the Issuer, the Owner Trustee or the Indenture Trustee with
respect to the manner in which it accomplishes the performance of its
obligations hereunder. Unless expressly authorized by the Issuer hereunder or
otherwise, the Administrator shall have no authority to act for or represent the
Issuer, the Owner Trustee or the Indenture Trustee, and shall not otherwise be
or be deemed an agent of the Issuer, the Owner Trustee or the Indenture Trustee.

      6. NO JOINT VENTURE. Nothing contained in this Agreement shall (i)
constitute the Administrator and any of the Issuer, the Owner Trustee or the
Indenture Trustee as members of any partnership, joint venture, association,
syndicate, unincorporated business or other separate entity, (ii) be construed
to impose any liability as such on any of them or (iii) be deemed



                                       7
<PAGE>
to confer on any of them any express, implied or apparent authority to incur any
obligation or liability on behalf of the others.

      7. OTHER ACTIVITIES OF ADMINISTRATOR. Nothing herein shall prevent the
Administrator or its Affiliates from engaging in other businesses or, in its or
their sole discretion, from acting as an administrator for any other person or
entity, or in a similar capacity therefor, even though such person or entity may
engage in business activities similar to those of the Issuer, the Owner Trustee
or the Indenture Trustee.

      8. TERM OF AGREEMENT; RESIGNATION AND REMOVAL OF ADMINISTRATOR.

            (a) This Agreement shall continue in force until the termination of
      the Issuer, upon which event this Agreement shall automatically terminate.

            (b) Subject to Sections 8(e) and 8(f), the Administrator may resign
      by providing the Issuer with at least 30 days' prior written notice.

            (c) Subject to Sections 8(e) and 8(f), the Issuer may remove the
      Administrator without cause by providing the Administrator at least 30
      days' prior written notice.

            (d) Subject to Sections 8(e) and 8(f), at the sole option of the
      Issuer, the Administrator may be removed immediately upon written notice
      of termination from the Issuer to the Administrator if any of the
      following events shall occur:

                  (i) the Administrator shall fail to perform in any material
            respect any of its duties under this Agreement and, after notice of
            such default, shall not cure such default within 10 days (or, if
            such default cannot be cured in such time, shall not give within
            such 10 days such assurance of timely and complete cure as shall be
            reasonably satisfactory to the Issuer);

                  (ii) the entry of a decree or order by a court or agency or
            supervisory authority having jurisdiction in the premises for the
            appointment of a trustee in bankruptcy, conservator, receiver or
            liquidator for the Administrator in any bankruptcy, insolvency,
            readjustment of debt, marshalling of assets and liabilities or
            similar proceedings, or for the winding up or liquidation of their
            respective affairs, and the continuance of any such decree or order
            unstayed and in effect for a period of 90 consecutive days; or

                  (iii) the consent by the Administrator to the appointment of a
            trustee in bankruptcy, conservator or receiver or liquidator in any
            bankruptcy, insolvency, readjustment of debt, marshalling of assets
            and liabilities or similar proceedings of or relating to the
            Administrator of or relating to substantially all of their property,
            or the Administrator shall admit in writing its inability to pay its
            debts generally as they become due, file a petition to take
            advantage of any applicable insolvency or reorganization statute,
            make an assignment for the benefit of its creditors, or voluntarily
            suspend payment of its obligations.

                  The Administrator agrees that if any of the events specified
      in clauses (ii) or (iii) of this Section shall occur, it shall give
      written notice thereof to the Issuer, the Owner Trustee and the Indenture
      Trustee within seven days after the occurrence of such event.

            (e) No resignation or removal of the Administrator pursuant to this
      Section shall be effective until (i) a successor Administrator shall have
      been appointed by the Issuer and (ii) such successor Administrator shall
      have agreed in writing to be bound by the terms of this Agreement on
      substantially the same terms as the Administrator is bound hereunder.

            (f) The appointment of any successor Administrator shall be
      effective only after each Rating Agency (other than Moody's) has provided
      to the Owner Trustee and the Indenture Trustee notice that the proposed
      appointment will not result in the reduction or withdrawal of any rating,
      if any, then assigned by such Rating Agency to any Class of Notes or the
      Certificates. Promptly after the appointment of any successor
      Administrator, the Owner Trustee will provide notice of such appointment
      to Moody's (so long as Moody's is then rating any outstanding Notes).

            (g) Subject to Section 8(e) and 8(f), the Administrator acknowledges
      that upon the appointment of a Successor Servicer pursuant to the Sale and
      Servicing Agreement, the Administrator shall immediately resign and such
      Successor Servicer shall automatically succeed to the rights, duties and
      obligations of the Administrator under this Agreement.

      9. ACTION UPON TERMINATION, RESIGNATION OR REMOVAL. Promptly upon the
effective date of termination of this Agreement pursuant to Section 8(a) or the
resignation or removal of the Administrator pursuant to Section 8(b) or (c) or
(d), the Administrator shall be entitled to be paid all fees and reimbursable
expenses accruing to it to the date of such termination, resignation or removal.
The Administrator shall forthwith upon such termination pursuant to Section 8(a)
deliver to or to the order of the Issuer all property and documents of or
relating to the Collateral then in the custody of the Administrator. In the
event of the resignation or removal of the Administrator pursuant to Section
8(b) or (c) or (d), the Administrator shall cooperate with the Issuer and take
all reasonable steps requested to assist the Issuer in making an orderly
transfer of the duties of the Administrator.

      10. NOTICES. Any notice, report or other communication given hereunder
shall be in writing and addressed as follows:

      11. AMENDMENTS. This Agreement may be amended from time to time by a
written amendment duly executed and delivered by the Issuer, the Administrator,
and the Indenture Trustee, with the consent of the Owner Trustee but without the
consent of any Noteholders or the Certificateholders, for the purpose of adding
any provisions to or modifying or changing in any manner or eliminating any of
the provisions of this Agreement, provided that such amendment does not and will
not, in the Opinion of Counsel satisfactory to the Indenture Trustee, materially
and adversely affect the interest of any Noteholder or Certificateholder. This
Agreement may also be amended from time to time by the Issuer, the
Administrator, and the Indenture Trustee with the consent of the Owner Trustee
and (i) the holders of Notes evidencing a majority of the Outstanding Amount of
the Notes, voting as a single class; or (ii) in the case of any amendment that
does not adversely affect the Indenture Trustee or the Noteholders (as evidenced
by an Officer's Certificate of the Servicer and an outside Opinion of Counsel
indicating that such amendment will not adversely affect the Indenture Trustee
or the Noteholders), the holders of the Certificates evidencing a majority of
the outstanding Certificate Balance of the Certificates (but excluding for
purposes of calculation and action all Certificates held by the Seller, the
Servicer or any of their Affiliates unless at such time all Certificates are
then owned by the Seller, the Servicer and their Affiliates), for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Agreement



                                       10
<PAGE>
or of modifying in any manner the rights of those Noteholders or
Certificateholders which are not covered by the immediately preceding sentence.

      12. SUCCESSOR AND ASSIGNS. This Agreement may not be assigned by the
Administrator unless such assignment is consented to in writing by the Issuer,
the Owner Trustee and the Indenture Trustee, and the conditions precedent to
appointment of a successor Administrator set forth in Section 8 are satisfied.
An assignment with such consent and satisfaction, if accepted by the assignee,
shall bind the assignee hereunder in the same manner as the Administrator is
bound hereunder. Notwithstanding the foregoing, this Agreement may be assigned
by the Administrator without the consent of the Issuer, the Owner Trustee and
the Indenture Trustee to a corporation or other organization that is a successor
(by merger, consolidation or purchase of assets) to the Administrator, provided
that such successor organization executes and delivers to the Issuer, the Owner
Trustee and the Indenture Trustee an agreement in which such corporation or
other organization agrees to be bound hereunder by the terms of said assignment
in the same manner as the Administrator is bound hereunder. Subject to the
foregoing, this Agreement shall bind any successors or assigns of the parties
hereto.

      13. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York, without reference to its
conflict of law provisions (other than Section 5-1401 of the General Obligations
Law of the State of New York), and the obligations, rights and remedies of the
parties hereunder shall be determined in accordance with such laws.

      14. NO PETITION. The Administrator, by entering into this Administration
Agreement, hereby covenants and agrees that it will not at any time institute
against the Issuer, or join in any institution against the Issuer of any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings,
or other proceedings under any United States federal or state bankruptcy or
similar law, in connection with any obligations relating to the Notes, the
Certificates or any of the Basic Documents.

      15. HEADINGS. The section headings hereof have been inserted for
convenience of reference only and shall not be construed to affect the meaning,
construction or effect of this Agreement.

      16. COUNTERPARTS. This Agreement may be executed in counterparts, each of
which when so executed shall together constitute but one and the same agreement.

      17. SEVERABILITY OF PROVISIONS. If any one or more of the agreements,
provisions or terms of this Agreement shall be for any reason whatsoever held
invalid or unenforceable in any jurisdiction, then such agreements, provisions
or terms shall be deemed severable from the remaining covenants, agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Agreement or the other rights of
the parties hereto.

      18. NOT APPLICABLE TO NMAC IN OTHER CAPACITIES. Nothing in this Agreement
shall affect any obligation, right or benefit NMAC may have in any other
capacity or under any Basic Document.

had solely to the assets of the Issuer.
