            consummation by it of the transactions contemplated thereby or
            hereby nor compliance by it with any of the terms or provisions

                    Termination of Interim Trust Agreement

      This Agreement (other than Article VI) and the trust created hereby shall

                                 ARTICLE VIII

                  Successor Interim Eligible Lender Trustees

      SECTION 8.1 Eligibility Requirements for Interim Eligible Lender Trustee.
The Interim Eligible Lender Trustee shall at all times be a corporation or
association (i) qualifying as an "eligible lender" as such term is defined in
Section 435(d) of the Higher Education Act for purposes of holding legal title
to the Interim Trust Loans on behalf and for the benefit of the Seller, with a
valid lender identification number with respect to the Interim Trust Loans from
the Department; and (ii) being authorized to exercise corporate trust powers and
hold legal title to the Interim Trust Loans. In case at any time the Interim
Eligible Lender Trustee shall cease to be eligible in accordance with the
provisions of this Section, the Interim Eligible Lender Trustee shall resign
immediately in the manner and with the effect specified in Section 8.2.

      SECTION 8.2 Resignation or Removal of Interim Eligible Lender Trustee. The
Interim Eligible Lender Trustee may at any time resign and be discharged from
the trust hereby created by giving written notice thereof to the Seller. Upon
receiving such notice of resignation, the Seller shall promptly appoint a
successor Interim Eligible Lender Trustee meeting the eligibility requirements
of Section 8.1 by written instrument, in duplicate, one copy of which instrument
shall be delivered to the resigning Interim Eligible Lender Trustee and one copy
to the successor Interim Eligible Lender Trustee. If no successor Interim
Eligible Lender Trustee shall have been so appointed and have


                                       8
<PAGE>

accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Interim Eligible Lender Trustee may petition any
court of competent jurisdiction for the appointment of a successor Interim
Eligible Lender Trustee; provided, however, that such right to appoint or to
petition for the appointment of any such successor shall in no event relieve the
resigning Interim Eligible Lender Trustee from any obligations otherwise imposed
on it under this Agreement, the Purchase Agreement or the Sale Agreement until
such successor has in fact assumed such appointment.

      If at any time the Interim Eligible Lender Trustee shall cease to be or
shall be likely to cease to be eligible in accordance with the provisions of
Section 8.1 and shall fail to resign after written request therefor by the
Seller, then the Seller may remove the Interim Eligible Lender Trustee. If the
Seller shall remove the Interim Eligible Lender Trustee under the authority of
the immediately preceding sentence, the Seller shall promptly appoint a
successor Interim Eligible Lender Trustee by written instrument, in duplicate,
one copy of which instrument shall be delivered to the outgoing Interim Eligible
Lender Trustee so removed and one copy to the successor Interim Eligible Lender
Trustee together with payment of all fees owed to the outgoing Interim Eligible
Lender Trustee.

      Any resignation or removal of the Interim Eligible Lender Trustee and
appointment of a successor Interim Eligible Lender Trustee pursuant to any of
the provisions of this Section shall not become effective until acceptance of
appointment by the successor Interim Eligible Lender Trustee pursuant to Section
8.3 and payment of all fees and expenses owed to the outgoing Interim Eligible
Lender Trustee.

      SECTION 8.3 Successor Interim Eligible Lender Trustee. Any successor
Interim Eligible Lender Trustee appointed pursuant to Section 8.2 shall execute,
acknowledge and deliver to the Seller and to its predecessor Interim Eligible
Lender Trustee an instrument accepting such appointment under this Agreement,
and thereupon the resignation or removal of the predecessor Interim Eligible
Lender Trustee shall become effective and such successor Interim Eligible Lender
Trustee, without any further act, deed or conveyance, shall become fully vested
with all the rights, powers, duties and obligations of its predecessor under
this Agreement, with like effect as if originally named as Interim Eligible
Lender Trustee. The predecessor Interim Eligible Lender Trustee shall upon
payment of its fees and expenses deliver to the successor Interim Eligible
Lender Trustee all documents,


                                       9
<PAGE>

statements, moneys and properties held by it under this Agreement and shall
assign, if permissible, to the successor Interim Eligible Lender Trustee any
lender identification number obtained from the Department with respect to the

                                 Miscellaneous

      SECTION 9.1 Supplements and Amendments. This Agreement may be amended by
the Seller and the Interim Eligible Lender Trustee, with prior written notice to
the Rating Agencies, without the consent of any of the Noteholders or the
Certificateholders, to cure any ambiguity, to correct or supplement any
provisions in this Agreement or for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions in this Agreement or
of modifying in any manner the rights of the Noteholders or the
Certificateholders; provided, however, that such action shall not, as evidenced
by an Opinion of Counsel, adversely affect in any material respect the interests
of any


                                       10

Noteholder or Certificateholder.

      This Agreement may also be amended from time to time by the Seller and the
Interim Eligible Lender Trustee, with prior written notice to the Rating
Agencies, with the consent of (i) the Noteholders of Notes evidencing not less
than a majority of the Outstanding Amount of the Notes and (ii) the
Certificateholders of Certificates evidencing not less than a majority of the
Certificate Balance, 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 the Certificateholders;
provided, however, that no such amendment shall (a) increase or reduce in any
manner the amount of, or accelerate or delay the timing of, collections of
payments on Trust Student Loans or distributions that shall be required to be
made for the benefit of the Noteholders or the Certificateholders or (b) reduce
the aforesaid percentage of the Outstanding Amount of the Notes and the
Certificate Balance required to consent to any such amendment, without the
consent of all the outstanding Noteholders and Certificateholders.

      Promptly after the execution of any such amendment or consent, the Interim
Eligible Lender Trustee shall furnish written notification of the substance of
such amendment or consent to each Certificateholder, the Indenture Trustee and
each of the Rating Agencies.

      It shall not be necessary for the consent of Certificateholders, the
Noteholders or the Indenture Trustee pursuant to this Section to approve the
particular form of any proposed amendment or consent, but it shall be sufficient
if such consent shall approve the substance thereof. The manner of obtaining
such consents (and any other consents of Certificateholders provided for in this
Agreement or in any other Basic Document) and of evidencing the authorization of
the execution thereof by Certificateholders shall be subject to such reasonable
requirements as the Interim Eligible Lender Trustee may prescribe.

      Prior to the execution of any amendment to this Agreement, the Interim
Eligible Lender Trustee shall be entitled to receive and rely upon an Opinion of
Counsel stating that the execution of such amendment is authorized or permitted
by this Agreement. The Interim Eligible Lender Trustee may, but shall not be
obligated to, enter into any such amendment which affects the Interim Eligible
Lender Trustee's own rights, duties or immunities under

      SECTION 9.3 Severability. Any provision of this Agreement that is
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 9.4 Separate Counterparts. This Agreement may be executed by the
parties hereto in separate counterparts, each of which when so executed and
delivered shall be an original, but all such counterparts shall together
