                  indemnify the injured party for all losses, claims, damages,
                  liabilities and expenses of the Trust (including Expenses, to
                  the extent that the assets of the Trust that would remain if
                  all of the Notes were paid in full would not be sufficient to
                  pay any such liabilities, or if such liabilities in fact are
                  not paid out of the Trust Estate) to the extent that the
                  Depositor would be liable if the Trust were a partnership
                  under the Delaware Revised Uniform Limited Partnership Act in
                  which the Depositor were a general partner; provided, however,
                  that the Depositor shall not be liable for -------- -------
                  any losses incurred by a beneficial owner of a Note in its
                  capacity as a holder of limited recourse debt or to any holder
                  of the Excess Distribution Certificate. In addition, any third
                  party creditors of the Trust (other than in connection with
                  the obligations to Noteholders excepted above) shall be third
                  party beneficiaries of this paragraph.

             (b)  No holder of the Excess Distribution Certificate (in such
                  capacity) shall have any personal liability for any liability
                  or obligation of the Trust.

             SECTION 2.8 Title to Trust Property. Legal title to all of the
                         -----------------------
Trust Estate shall be vested at all times in the Trust as a separate legal
entity except where applicable law in any jurisdiction requires title to any
part of the Trust Estate to be vested in a trustee or trustees, in which case
title shall be deemed to be vested in the Eligible Lender Trustee, a co-trustee
and/or a separate trustee, as the case may be; provided that legal title to the
Trust Student Loans shall be vested at all times in the Eligible Lender Trustee
on behalf of the Trust.

             SECTION 2.9 Representations, Warranties, and Covenants of the
                         -------------------------------------------------
Depositor. The Depositor hereby represents, warrants and covenants to the
---------

             (a)  The Depositor is duly organized and validly existing as a

                  State of Delaware, with power and authority to own its
                  properties and to conduct its business as such properties are
                  currently owned and such business is presently conducted.

             (b)  The Depositor has the corporate power and authority to execute
                  and deliver this Agreement and to carry out its terms; the
                  Depositor has full corporate power and authority to sell and
                  assign the property to be sold and assigned to and deposited
                  with the Trust (or with the Eligible Lender Trustee on behalf
                  of the Trust) and the Depositor has duly authorized such sale
                  and assignment and deposit to the Trust (or to the Eligible
                  Lender Trustee on behalf of the Trust) by all necessary
                  corporate action; and the execution, delivery and performance
                  of this Agreement has been duly authorized by the Depositor by
                  all necessary corporate action.

             (c)  This Agreement constitutes a legal, valid and binding
                  obligation of the Depositor enforceable in accordance with its
                  terms, subject to applicable bankruptcy, insolvency,
                  reorganization and similar laws relating to creditors' rights
                  generally and subject to general principles of equity.

             (d)  The consummation of the transactions contemplated by this
                  Agreement and the fulfillment of the terms hereof do not
                  conflict with, result in any breach of any of the terms and
                  provisions of, or constitute (with or without notice or lapse
                  of time or both) a default under, the Certificate of
                  Incorporation or by-laws of the Depositor, or any indenture,

                  (other than pursuant to the Basic Documents); nor violate any

         (a) General. The Excess Distribution Certificate shall be issued
             -------
without denomination. The Excess Distribution Certificate shall receive payments
as provided in Sections 2.8.1C.1(F)(ii) and 2.8.2B.2 of the Administration
Agreement. The Excess Distribution Certificate shall be executed on behalf of
the Trust by manual or facsimile signature of an authorized officer of the
Eligible Lender Trustee. An Excess Distribution Certificate bearing the manual
or facsimile signatures of individuals who were, at the time when such
signatures were affixed, authorized to sign on behalf of the Trust, shall be
valid and binding obligations of the Trust, notwithstanding that such
individuals or any of them shall have ceased to be so authorized prior to the
authentication and delivery of such Excess Distribution Certificate or did not
hold such offices at the date of authentication and delivery of such Excess
Distribution Certificate.

         (b) Authentication. Concurrently with the sale of the Trust Student
             --------------
Loans to the Trust pursuant to the Purchase Agreement, the Eligible Lender
Trustee shall cause the Excess Distribution Certificate to be executed on behalf
of the Trust, authenticated and delivered to or upon the written order of the
Depositor, signed by its chairman of the board, its president or any vice
president, without further action by the Depositor. No Excess Distribution
Certificate shall entitle its holder to any benefit under this Agreement, or
shall be valid for any purpose, unless there shall appear on such Excess
Distribution Certificate a certificate of authentication substantially in the
form set forth in Exhibit C, executed by the Eligible Lender Trustee or JPMorgan
Chase Bank, as the Eligible Lender Trustee's authenticating agent, by manual
signature; such authentication shall constitute conclusive evidence that such
Excess Distribution Certificate shall have been duly authenticated and delivered
hereunder. The Excess Distribution Certificate shall be dated the date of its
authentication. No further Excess Distribution Certificates shall be issued
except pursuant to paragraph (c) or (d) below.

         (c) Registration of Transfer and Exchange. The Excess Distribution
             -------------------------------------
Certificate Registrar shall keep or cause to be kept, at the office or agency
maintained pursuant to paragraph (f) below, an Excess Distribution Certificate
Register in which, subject to such reasonable regulations as it may prescribe,
the Eligible Lender Trustee shall provide for the registration of the Excess
Distribution Certificate and of transfers and exchanges of the Excess
Distribution Certificate as herein provided. Chase Manhattan Bank USA, National
Association shall be the initial Excess Distribution Certificate Registrar.

<PAGE>

         Upon surrender for registration of transfer of the Excess Distribution
Certificate at the office or agency maintained pursuant to paragraph (f) below,
the Eligible Lender Trustee shall execute, authenticate and deliver (or shall
cause JPMorgan Bank as its authenticating agent to authenticate and deliver), in
the name of the designated transferee, a new Excess Distribution Certificate
dated the date of authentication by the Eligible Lender Trustee or any
authenticating agent. At the option of the holder of the Excess Distribution
Certificate, the Excess Distribution Certificate may be exchanged for another
Excess Distribution Certificate upon surrender of the Excess Distribution
Certificate to be exchanged at the office or agency maintained pursuant to
paragraph (f) below.

         An Excess Distribution Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Eligible Lender Trustee and
the Excess Distribution Certificate Registrar duly executed by the holder
thereof or his attorney duly authorized in writing, with such signature
guaranteed by a member firm of the New York Stock Exchange or a commercial bank
or trust company. An Excess Distribution Certificate surrendered for
registration of transfer or exchange shall be cancelled and subsequently
disposed of by the Eligible Lender Trustee in accordance with its customary
practice.

         No service charge shall be made for any registration of transfer or
exchange of the Excess Distribution Certificate, but the Eligible Lender Trustee
or the Excess Distribution Certificate Registrar may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer or exchange of the Excess Distribution Certificate.

         The preceding provisions of this Section notwithstanding, the Eligible
Lender Trustee shall not be required to make and the Excess Distribution
Certificate Registrar need not register transfers or exchanges of the Excess
Distribution Certificate for a period of 15 days preceding any Distribution Date
with respect to the Excess Distribution Certificate.

         The Excess Distribution Certificate and any beneficial interest in the
Excess Distribution Certificate may not be acquired by (a) employee benefit
plans (as defined in section 3(3) of ERISA) that are subject to the provisions
of Title I of ERISA, (b) plans described in section 4975(e)(1) of the Code,
including individual retirement accounts described in Section 408(a) of the Code
or Keogh plans, or (c) Benefit Plans. By accepting and holding the Excess
Distribution Certificate or an interest therein, the holder thereof shall be
deemed to have represented and warranted that it is not a Benefit Plan, is not
purchasing the Excess Distribution Certificate on behalf of a Benefit Plan and
is not using assets of a Plan to purchase the Excess Distribution Certificate
and to have agreed that if the Excess Distribution Certificate is deemed to be a
plan asset, the holder thereof will promptly dispose of the Excess Distribution
Certificate.

         (d) Mutilated, Destroyed, Lost or Stolen Excess Distribution

surrendered to the Excess Distribution Certificate Registrar, or if the Excess
Distribution Certificate Registrar shall receive evidence to its

<PAGE>

satisfaction of the destruction, loss or theft of the Excess Distribution
Certificate, and (2) there shall be delivered to the Excess Distribution
Certificate Registrar and the Eligible Lender Trustee such security or indemnity
as may be required by them to save each of them and the Trust harmless, then in
the absence of notice that such Excess Distribution Certificate shall have been
acquired by a bona fide purchaser, the Eligible Lender Trustee on behalf of the
Trust shall execute and the Eligible Lender Trustee shall authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Excess Distribution Certificate, a new Excess Distribution Certificate of
like tenor. In connection with the issuance of any new Excess Distribution
Certificate under this Section, the Eligible Lender Trustee and the Excess
Distribution Certificate Registrar may require the payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
therewith. Any duplicate Excess Distribution Certificate issued pursuant to this
paragraph shall constitute conclusive evidence of ownership in the Trust, as if
originally issued, whether or not the lost, stolen or destroyed Excess
Distribution Certificate shall be found at any time.

         (e) Persons Deemed Owners. Prior to due presentation of the Excess
             ---------------------
Distribution Certificate for registration of transfer, the Eligible Lender
Trustee and the Excess Distribution Certificate Registrar and any agent of
either of them may treat the Person in whose name the Excess Distribution
Certificate shall be registered in the Excess Distribution Certificate Register
as the owner of such Excess Distribution Certificate for the purpose of
receiving distributions thereon and for all other purposes whatsoever, and
neither the Eligible Lender Trustee, the Excess Distribution Certificate
Registrar nor any agent thereof shall be bound by any notice to the contrary.

         (f) Maintenance of Office or Agency. The Eligible Lender Trustee shall
             -------------------------------
maintain in the Borough of Manhattan, The City of New York, an office or offices
or agency or agencies where the Excess Distribution Certificate may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Eligible Lender Trustee in respect of the Excess
Distribution Certificate may be served.

         (g) Appointment of Excess Distribution Certificate Paying Agent. The
             -----------------------------------------------------------
Excess Distribution Certificate Paying Agent shall make distributions to the
holder of the Excess Distribution Certificate from the amounts received from the
Indenture Trustee pursuant to Sections 2.8.1C.1F(ii) and 2.8.2B.2 of the
Administration Agreement and shall report the amounts of such distributions to
the Eligible Lender Trustee. Any Excess Distribution Certificate Paying Agent
shall have the revocable power to receive such funds from the Indenture Trustee
for the purpose of making the distributions referred to above. The Eligible
Lender Trustee may revoke such power and remove the Excess Distribution
Certificate Paying Agent if the Eligible Lender Trustee determines in its sole
discretion that the Excess Distribution Certificate Paying Agent shall have
failed to perform its obligations under this Agreement in any material respect.
The Excess Distribution Certificate Paying Agent shall initially be the Eligible
Lender Trustee, and any co-paying agent chosen by the Eligible Lender Trustee
and consented to by the Administrator (which consent shall not be unreasonably
withheld). The co-paying agent shall initially be the Indenture Trustee. The
Eligible Lender Trustee shall be permitted to resign as Excess Distribution
Certificate Paying Agent upon 30 days' written notice to the Eligible

Lender Trustee. In the event that the Eligible Lender Trustee shall no longer be
the Excess Distribution Certificate Paying Agent, the Eligible Lender Trustee
shall appoint a successor to act as Excess Distribution Certificate Paying Agent
(which shall be a bank or trust company). The Eligible Lender Trustee shall
cause such successor Excess Distribution Certificate Paying Agent or any
additional Excess Distribution Certificate Paying Agent appointed by the
Eligible Lender Trustee to execute and deliver to the Eligible Lender Trustee an
instrument in which such successor Excess Distribution Certificate Paying Agent
or additional Excess Distribution Certificate Paying Agent shall agree with the
Eligible Lender Trustee that as Excess Distribution Certificate Paying Agent,
such successor Excess Distribution Certificate Paying Agent or additional Excess
Distribution Certificate Paying Agent will hold all sums, if any, held by it for
payment to the holder of the Excess Distribution Certificate in trust for the
benefit of such holder until such sums shall be paid to such holder. The Excess
Distribution Certificate Paying Agent shall return all unclaimed funds to the
Eligible Lender Trustee and upon removal of an Excess Distribution Certificate
Paying Agent such Excess Distribution Certificate Paying Agent shall also return
all funds in its possession to the Eligible Lender Trustee. The provisions of
Sections 7.1, 7.3, 7.4, 7.5 and 8.1 shall apply to the Eligible Lender Trustee
also in its role as Excess Distribution Certificate Paying Agent, for so long as
the Eligible Lender Trustee shall act as Certificate Paying Agent and, to the
extent applicable, to any other paying agent appointed hereunder. Any reference
in this Agreement to the Excess Distribution Certificate Paying Agent shall
include any co-paying agent unless the context requires otherwise.

authorized and directed to execute and deliver the Basic Documents to which the

otherwise follow the direction of and cooperate with the Servicer in submitting,

Trustee hereunder or under any other Basic Document, and the Eligible Lender
Trustee shall not be held liable for the default or failure of the Administrator
to carry out its obligations under the Administration Agreement. Except as

         SECTION 6.3 Action upon Instruction.
                     -----------------------

         (a)  [Reserved]

         (b)  The Eligible Lender Trustee shall not be required to take any
              action hereunder or under any other Basic Document if the Eligible
              Lender Trustee shall have reasonably determined, or shall have
              been advised by counsel, that such action is likely to result in
              liability on the part of the Eligible Lender Trustee or is
              contrary to the terms hereof, any other Basic Document or is
              otherwise contrary to law.

         (c)  Whenever the Eligible Lender Trustee is unable to determine the
              appropriate course of action between alternative courses and
              actions permitted or required by the terms of this Agreement or
              under any other Basic Document, the Eligible Lender Trustee shall
              promptly give notice (in such form as shall be appropriate under
              the circumstances) to the Depositor requiring instruction as to
              the course of action to be adopted, and to the extent the Eligible
              Lender Trustee acts in good faith in accordance with any written
              instruction of the Depositor received, the Eligible Lender Trustee
              shall not be liable on account of such action to any Person. If
              the Eligible Lender Trustee shall not have received appropriate
              instruction within 10 days of such notice (or within such shorter
              period of time as reasonably may be specified in such notice or
              may be necessary under the circumstances) it may, but shall be
              under no duty to, take or refrain from taking such action, not
              inconsistent with this Agreement, the other Basic Documents, as it
              shall deem to be in the best interests of the Depositor, and shall
              have no liability to any Person for such action or inaction.

         (d)  In the event that the Eligible Lender Trustee is unsure as to the
              application of any provision of this Agreement, any other Basic
              Document or any such provision is ambiguous as to its application,
              or is, or appears to be, in conflict with any other applicable
              provision, or in the event that this Agreement permits any
              determination by the Eligible Lender Trustee or is silent or is
              incomplete as to the course of action that the Eligible Lender
              Trustee is required to take with respect to a particular set of
              facts, the Eligible Lender Trustee may give notice (in such form
              as shall be appropriate under the circumstances) to the Depositor

successor Eligible Lender Trustee meeting the eligibility requirements of
Section 10.1 by written instrument, in duplicate, one copy of which instrument
shall be delivered to the resigning Eligible Lender Trustee and one copy to the
successor Eligible Lender Trustee. If no successor Eligible Lender Trustee shall
have been so appointed and have accepted appointment within 30 days after the

be likely to cease to be eligible in accordance with the provisions of Section
10.1 and shall fail to resign after written

request therefor by the Administrator, or if at any time an Insolvency Event
with respect to the Eligible Lender Trustee shall have occurred and be
continuing, then the Administrator may remove the Eligible Lender Trustee. If
the Administrator shall remove the Eligible Lender Trustee under the authority
of the immediately preceding sentence, the Administrator shall promptly appoint
a successor Eligible Lender Trustee by written instrument, in duplicate, one
copy of which instrument shall be delivered to the outgoing Eligible Lender
Trustee so removed and one copy to the successor Eligible Lender Trustee and
payment of all fees owed to the outgoing Eligible Lender Trustee.

         Any resignation or removal of the Eligible Lender Trustee and
appointment of a successor Eligible Lender Trustee pursuant to any of the
provisions of this Section shall not become effective until acceptance of
appointment by the successor Eligible Lender Trustee pursuant to Section 10.3,
payment of all fees and expenses owed to the outgoing Eligible Lender Trustee
and the filing of a certificate of amendment to the Trust's certificate of trust
pursuant to Section 3810(b) of the Delaware Business Trust Act. The
Administrator shall provide notice of such resignation or removal of the
Eligible Lender Trustee and to each of the Rating Agencies.

         SECTION 10.3 Successor Eligible Lender Trustee. Any successor Eligible
                      ---------------------------------
Lender Trustee appointed pursuant to Section 10.2 shall execute, acknowledge and
deliver to the Administrator and to its predecessor Eligible Lender Trustee an
instrument accepting such appointment under this Agreement, and thereupon the
resignation or removal of the predecessor Eligible Lender Trustee shall become
effective and such successor 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 Eligible Lender Trustee. The predecessor Eligible
Lender Trustee shall upon payment of its fees and expenses deliver to the
successor Eligible Lender Trustee all documents, statements, moneys and
properties held by it under this Agreement and shall assign, if permissible, to
the successor Eligible Lender Trustee the lender identification number obtained
from the Department on behalf of the Trust; and the Administrator and the
predecessor 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 Eligible Lender Trustee all such rights,
powers, duties and obligations.

         No successor Eligible Lender Trustee shall accept such appointment as
provided in this Section unless at the time of such acceptance such successor
Eligible Lender Trustee shall be eligible pursuant to Section 10.1.

         Upon acceptance of appointment by a successor Eligible Lender Trustee
pursuant to this Section, the Administrator shall mail notice of the successor
of such Eligible Lender Trustee to the holder of the Excess Distribution
Certificate, the Indenture Trustee, the Noteholders, the Rating Agencies and the
Swap Counterparty. If the Administrator shall fail to mail such notice within 10
days after acceptance of appointment by the successor Eligible Lender Trustee,
the successor Eligible Lender Trustee shall cause such notice to be mailed at
the expense of the Administrator.

hereto, anything herein to the contrary notwithstanding, be the successor of the
Eligible Lender Trustee hereunder; provided that such corporation shall be
                                   --------
eligible pursuant to Section 10.1; and provided further that the Eligible Lender
                                       -------- -------
Trustee shall mail notice of such merger or consolidation to the Rating Agencies
not less than 15 days prior to the effective date thereof.

         SECTION 10.5 Appointment of Co-Eligible Lender Trustee or Separate
                      -----------------------------------------------------
Eligible Lender Trustee. Notwithstanding any other provisions of this Agreement,
-----------------------
at any time, for the purpose of meeting any legal requirements of any
jurisdiction in which any part of the Trust may at the time be located, the
Administrator and the Eligible Lender Trustee acting jointly shall have the
power and shall execute and deliver all instruments to appoint one or more
Persons approved by the Eligible Lender Trustee, meeting the eligibility
requirements of clauses (i) through (iii) of Section 10.1, to act as co-trustee,
jointly with the Eligible Lender Trustee, or separate trustee or separate
trustees, of all or any part of the Trust Estate, and to vest in such Person, in
such capacity, such title to the Trust Estate, or any part thereof, and, subject
to the other provisions of this Section, such powers, duties, obligations,
rights and trusts as the Administrator and the Eligible Lender Trustee may
consider necessary or desirable. If the Administrator shall not have joined in
such appointment within 15 days after the receipt by it of a request so to do,
the Eligible Lender Trustee alone shall have the power to make such appointment.
No co-trustee or separate trustee under this Agreement shall be required to meet
the terms of eligibility as a successor trustee pursuant to clauses (iv), (v)
and (vi) of Section 10.1 and no notice of the appointment of any co-trustee or
separate trustee shall be required pursuant to Section 10.3.

         Each separate trustee and co-trustee shall, to the extent permitted by
law, be appointed and act subject to the following provisions and conditions:

                  (i)  all rights, powers, duties, and obligations conferred or
         imposed upon the Eligible Lender Trustee shall be conferred upon and
         exercised or performed by the Eligible Lender Trustee and such separate
         trustee or co-trustee jointly (it being understood that such separate
         trustee or co-trustee is not authorized to act separately without the
         Eligible Lender Trustee joining in such act), except to the extent that
         under any law of any jurisdiction in which any particular act or acts
         are to be performed, the Eligible Lender Trustee shall be incompetent
         or unqualified to perform such act or acts, in which event such rights,
         powers, duties, and obligations (including the holding of title to the
         Trust or any portion thereof in any such jurisdiction) shall be
         exercised and performed singly by such separate trustee or co-trustee,
         solely at the direction of the Eligible Lender Trustee;

                  (ii) no trustee under this Agreement shall be personally
         liable by reason of any act or omission of any other trustee under this
         Agreement; and

                                       21

<PAGE>

               (iii) the Administrator and the Eligible Lender Trustee acting
         jointly may at any time accept the resignation of or remove any
         separate trustee or co-trustee.

         Any notice, request or other writing given to the Eligible Lender
Trustee shall be deemed to have been given to each of the then separate trustees
and co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Agreement and
the conditions of this Article. Each separate trustee and co-trustee, upon its
acceptance of the trusts conferred, shall be vested with the estates or property
specified in its instrument of appointment, either jointly with the Eligible
Lender Trustee or separately, as may be provided therein, subject to all the
provisions of this Agreement, specifically including every provision of this
Agreement relating to the conduct of, affecting the liability of, or affording
protection to, the Eligible Lender Trustee. Each such instrument shall be filed
with the Eligible Lender Trustee and a copy thereof given to the Administrator.

         Any separate trustee or co-trustee may at any time appoint the Eligible
Lender Trustee as its agent or attorney-in-fact with full power and authority,
to the extent not prohibited by law, to do any lawful act under or in respect of
this Agreement on its behalf and in its name. If any separate trustee or
co-trustee shall die, become incapable of acting, resign or be removed, all its
estates, properties, rights, remedies and trusts shall vest in and be exercised
by the Eligible Lender Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

                  [Reverse of Excess Distribution Certificate]

         This Excess Distribution Certificate does not represent an obligation
of, or an interest in, the Depositor, Sallie Mae Servicing L.P., as servicer
(the "Servicer"), Student Loan Marketing Association, as administrator (the
"Administrator"), the Eligible Lender Trustee or any affiliates of any of them,
and no recourse may be had against such parties or their assets, except as may
be expressly set forth or contemplated herein, in the Trust Agreement or in the
other Basic Documents. In addition, this Excess Distribution Certificate is not
guaranteed by any governmental agency or instrumentality and is limited in right
of payment to certain collections with respect to the Trust Student Loans, all
as more specifically set forth in the Administration Agreement. A copy of each
of the Trust Agreement, the Sale Agreement, the Purchase Agreement, the
Administration Agreement, the Servicing Agreement and the Indenture may be
examined during normal business hours at the principal office of the
Administrator, and at such other places, if any, designated by the
Administrator, by the holder of this Excess Distribution Certificate upon
request.

         The Trust Agreement permits, with certain exceptions therein provided,
the amendment thereof and the certification of the rights and obligations of the
Depositor and the rights of the holders of this Excess Distribution Certificate
under the Trust Agreement at any time by the Depositor and the Eligible Lender
Trustee with the consent of the holders of the Class A Notes and the Class B
Notes, each voting as a class evidencing not less than a majority of the
outstanding principal balance of each class of the Notes. The Trust Agreement
also permits the amendment thereof, in certain limited circumstances, without
the consent of the Noteholders.

         As provided in the Trust Agreement and subject to certain limitations
therein set forth, the transfer of this Excess Distribution Certificate is
registerable in the Excess Distribution Certificate Register upon surrender of
this Excess Distribution Certificate for registration of transfer at the offices
or agencies maintained by Chase Manhattan Bank USA, National Association in its
capacity as Excess Distribution Certificate Registrar, or by any successor
Excess Distribution Certificate Registrar, in the Borough of Manhattan, The City
of New York, accompanied by a written instrument of transfer in form
satisfactory to the Eligible Lender Trustee and the Excess Distribution
Certificate Registrar duly executed by the holder hereof or such holder's
attorney duly authorized in writing, and thereupon a new Excess Distribution
Certificate will be issued to the designated transferee.

                                       vi

<PAGE>

         As provided in the Trust Agreement and subject to certain limitations
therein set forth, this Excess Distribution Certificate is exchangeable for a
new Excess Distribution Certificate as requested by the holder surrendering the
same. No service charge will be made for any such registration of transfer or
exchange, but the Eligible Lender Trustee or the Excess Distribution Certificate
Registrar may require payment of a sum sufficient to cover any tax or
governmental charge payable in connection therewith.

         The Eligible Lender Trustee, the Certificate Registrar and any agent of
the Eligible Lender Trustee or the Excess Distribution Certificate Registrar may
treat the person in whose name this Excess Distribution Certificate is
registered as the owner hereof for all purposes, and none of the Eligible Lender
Trustee or the Excess Distribution Certificate Registrar or any such agent shall
be affected by any notice to the contrary.

         This Excess Distribution Certificate (including any beneficial interest
herein) may not be acquired by or for the account of (i) an employee benefit
plan (as defined in Section 3(3) of ERISA) that is subject to the provisions of
Title I of ERISA, (ii) a plan described in section 4975(e)(1) of the Internal
Revenue Code of 1986, as amended (the "Code"), including an individual
retirement account described in Section 408(a) of the Code or a Keogh plan or
(iii) any entity whose underlying assets include plan assets by reason of a
plan's investment in the entity (each, a "Benefit Plan"). By accepting and
holding this Excess Distribution Certificate, the holder hereof shall be deemed
to have represented and warranted that it is not a Benefit Plan, it is not
purchasing this Excess Distribution Certificate on behalf of a Benefit Plan, is
not using assets of a Benefit Plan to purchase this Excess Distribution
Certificate and to have agreed that if this Excess Distribution Certificate is
deemed to be a plan asset, the Holder will promptly dispose of this Excess
Distribution Certificate.

         The obligations and responsibilities created by the Trust Agreement and
the Trust created thereby shall terminate upon the payment to Noteholders and
the holder of this Excess Distribution Certificate of all amounts required to be
paid to them pursuant to the Trust Agreement, the Administration Agreement and
the Indenture and the disposition of all property held as part of the Trust. The
Depositor may at its option purchase the corpus of the Trust at a price
specified in the Administration Agreement; however, such right of purchase is
exercisable only on any Distribution Date on or after the date on which the Pool
Balance is less than or equal to 10% of the

                                       vii

<PAGE>

Initial Pool Balance. Any Trust Student Loans remaining in the Trust as of the
end of the Collection Period immediately preceding the Trust Auction Date will
be offered for sale by the Indenture Trustee by auction in accordance with the
procedure described in the Indenture.

         This Excess Distribution Certificate shall be construed in accordance
with the laws of the State of Delaware, without reference to its conflict of law
provisions, and the obligations, rights and remedies of the parties hereunder
shall be determined in accordance with such laws.
