          liability is not reasonably assured or provided to it.

          Agreement, the Sale Agreement or this Agreement, nor the consummation
          by it of the transactions contemplated thereby or hereby nor
          compliance by it with any of the terms or provisions thereof or hereof
          will contravene any Federal or Delaware state law, governmental rule
          or regulation governing the banking or trust powers of the Interim
          Eligible Lender Trustee or any judgment or order binding on it, or

                     TERMINATION OF INTERIM TRUST AGREEMENT

                                  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 Depositor, 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 Depositor. Upon
receiving such notice of resignation, the Depositor 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 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
Depositor, then the Depositor may remove the Interim Eligible Lender Trustee. If
the Depositor shall remove the Interim Eligible Lender Trustee under the
authority of the immediately preceding sentence, the Depositor shall promptly
appoint a successor Interim Eligible Lender Trustee by written instrument, in
duplicate, one copy of which

                                        6
<Page>

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 Depositor 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, 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 Interim Trust Loans; and the Depositor and the
predecessor Interim Eligible Lender Trustee shall execute and deliver such
instruments and do such other things as may reasonably be required for fully and
certainly vesting and confirming in the successor Interim Eligible Lender
Trustee all such rights, powers, duties and obligations.

     No successor Interim Eligible Lender Trustee shall accept such appointment
as provided in this Section unless at the time of such acceptance such successor
Interim Eligible Lender Trustee shall be eligible pursuant to Section 8.1.

     SECTION 8.4 MERGER OR CONSOLIDATION OF INTERIM ELIGIBLE LENDER TRUSTEE. Any
corporation into which the Interim Eligible Lender Trustee may be merged or
converted or with which it may be consolidated, or any corporation or banking
association resulting from any merger, conversion or consolidation to which the
Interim Eligible Lender Trustee shall be a party, or any corporation succeeding
to all or substantially all the corporate trust business of the Interim Eligible
Lender Trustee, shall, without the execution or filing of any instrument or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding, be the successor of the Interim Eligible Lender
Trustee hereunder; PROVIDED that such corporation or banking association shall
be eligible pursuant to Section 8.1.

                                  MISCELLANEOUS

     SECTION 9.1 SUPPLEMENTS AND AMENDMENTS. This Agreement may be amended by
the Depositor and the Interim Eligible Lender Trustee, with prior written notice
to the Rating Agencies, without the consent of any of the Noteholders, 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; PROVIDED, HOWEVER, that such action shall not, as evidenced
by an Opinion of Counsel, adversely affect in any material respect the interests
of any Noteholder.

     This Agreement may also be amended from time to time by the Depositor and
the Interim Eligible Lender Trustee, with prior written notice to the Rating
Agencies, with the consent of the Noteholders evidencing not less than a
majority of the Outstanding Amount of the Notes, 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;
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 (b) reduce the aforesaid percentage
of the Outstanding Amount of the Notes required to consent to any such
amendment, without the consent of all the outstanding Noteholders.

     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 the Indenture Trustee and each of the Rating
Agencies.

     It shall not be necessary for the consent of the Noteholders 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 of evidencing the
authorization of the execution thereof 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 this Agreement or
otherwise.

     SECTION 9.2 NOTICES. Unless otherwise expressly specified or permitted by
the terms hereof, all notices shall be in writing and shall be deemed given upon

Lender Trustee shall be deemed given only upon actual receipt by the Interim

written notice to each other party.

     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
constitute but one and the same instrument.
