            other things, accounting and reports to Owners; provided, however,
            that the Owner Trustee shall retain responsibility for the
            distribution of any Schedule K-1s necessary to enable each Owner to
            prepare its federal and state income tax returns.

                  (iv)  The Administrator shall satisfy its obligations with
            respect to clauses (ii) and (iii) above by retaining, at the expense
            of the Trust payable by the Administrator, a firm of independent
            public accountants (the "Accountants") acceptable to the Owner
            Trustee, which shall perform the obligations of the Administrator
            thereunder. In connection with paragraph (ii) above, the Accountants
            will provide prior to December 31, 2005, a letter in form and
            substance satisfactory to the Owner Trustee if any tax

                                       6
<PAGE>

            withholding is then required and the procedures to be followed with
            respect thereto to comply with the requirements of the Code. 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 resignation or
            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 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, the Administrator shall have notified the
            Owner Trustee of the proposed action and the Owner Trustee shall not
            have withheld consent or provided an alternative direction. For the
            purpose of the preceding sentence, "non-ministerial matters" shall
            include:

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

                        (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 Contracts);

                        (C)   the amendment, change or modification of the
                  Related Agreements;

                        (D)   the appointment of successor Note Registrars,
                  successor Paying Agents and successor Indenture Trustees
                  pursuant to the Indenture or the appointment of successor
                  Administrators or a successor Master Servicer, or the consent
                  to the assignment by any of the Note Registrar, the Paying
                  Agent or the Indenture Trustee of its obligations 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, (A) make any payments to the Noteholders under the Related
            Agreements, (B) take any other action that the Issuer directs the
            Administrator not to take on its behalf or (C) take any other action
            which may be construed as having the effect of varying the
            investment of the Holders.

                                       7

account and records relating to services performed hereunder, which books of
account and records shall be accessible for inspection by the Issuer and the
Company at any time during normal business hours.

Administrator's obligations under this Agreement and as reimbursement for its

Administrator shall furnish to the Issuer from time to time such additional

the manner in which it accomplishes the performance of its obligations
hereunder. Unless expressly authorized by the Issuer, the Administrator shall
have no authority to act for or represent the Issuer or the Owner Trustee in any
way and shall not otherwise be deemed an agent of the Issuer or the Owner
Trustee.

      Section 6. No Joint Venture. Nothing contained in this Agreement shall (i)
constitute the Administrator and either of the Issuer or the Owner 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 to confer on any of them
any express, implied or apparent authority to incur any obligation or liability
on behalf of the others.

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

      shall be reasonably satisfactory to the Issuer);

            (ii)  a court having jurisdiction in the premises shall enter a
      decree or order for relief, and such decree or order shall not have been
      vacated within 60 days, in respect of the Administrator in any involuntary

      custodian, trustee, sequestrator or similar official for the Administrator

      property, shall consent to the taking of possession by any such official
      of any substantial part of its property, shall make any general assignment
      for the benefit of creditors or shall fail generally to pay its debts as
      they become due.

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

      (d)   No resignation or removal of the Administrator pursuant to this

in writing to be bound by the terms of this Agreement in the same manner as the
Administrator is bound hereunder.

      Section 11. Amendments. This Agreement may be amended from time to time by
a written amendment duly executed and delivered by the parties hereto, with the
written consent of the Owner Trustee but without the consent of the Noteholders
and the Certificateholders, for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement or
of modifying in any manner the rights of the Noteholders or Certificateholders;
provided that such amendment 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 by the
parties hereto with the written consent of the Owner Trustee and the holders of
Notes evidencing at least a majority of the Outstanding Amount of the Notes and
the holders of Certificates evidencing at least a majority of the Certificate
Percentage for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of this Agreement or of modifying in any
manner the rights of Noteholders or the Certificateholders; provided, however,
that no such amendment may (i) increase or reduce in any manner the amount of,
or accelerate or delay the timing of, collections of payments on the Contracts

or Certificateholders or (ii) reduce the aforesaid percentage of the holders of

Notwithstanding the foregoing, the Administrator may not amend this Agreement

      Section 12. Successors and Assigns. This Agreement may not be assigned by

by the Issuer and the Owner Trustee and subject to the satisfaction of the
Rating Agency Condition in respect thereof. 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 or the Owner 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 form and substance reasonably satisfactory to the Owner Trustee
and the Indenture Trustee, 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.
