          necessary corporate action; and the execution, delivery and
          performance of this Agreement has been duly authorized by the
          Depositor by all necessary corporate action.

          administrative agency or other governmental instrumentality having
          jurisdiction over the Depositor or its properties.

     (e)  The Depositor agrees for the benefit of the Noteholders and the holder
          of the Excess Distribution Certificate that it will comply with each
          of the requirements set forth in Article IX, X, and XII of its

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 The Chase Manhattan
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 Registrar.

     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 The Chase Manhattan 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 Certificate.

evidence to its 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.

         -----------------------------------------------------------
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.

     (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.

          notice (in such form as shall be appropriate under the circumstances)
          to the Depositor requiring instruction as to the course of action to

          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

          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 requesting instruction and, to the
          extent that the Eligible Lender Trustee acts or refrains from acting
          in good faith in accordance with any such instruction received, the
          Eligible Lender Trustee shall not be liable, on account of such action
          or inaction, 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 or the other Basic
          Documents, as it shall deem to be in the best interest of the holder
          of the Excess Distribution Certificate, and shall have no liability to
          any Person for such action or inaction.

(vi) having (or having a parent which has) a rating in respect of its long-term
senior unsecured debt of at least BBB- (or the equivalent) by each of the Rating
Agencies (or which, if the long-term senior unsecured debt of such corporation
or association is not rated by any Rating Agency, shall have provided to the
Indenture Trustee written confirmation from such Rating Agency that the
appointment of such corporation or association to serve as Eligible Lender
Trustee will not result in and of itself in a reduction or withdrawal of the
then current rating of any of the Notes). If the Eligible Lender Trustee shall
publish reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purpose of this Section, the combined capital and surplus of the Eligible Lender
Trustee shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. In case at any time the
Eligible Lender Trustee shall cease to be eligible in accordance with the

                   -------------------------------------------------
Eligible Lender Trustee may at any time resign and be discharged from the trusts
hereby created by giving written notice thereof to the Administrator. Upon
receiving such notice of resignation, the Administrator shall promptly appoint a
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
giving of such notice of resignation, the resigning Eligible Lender Trustee may
petition any court of competent jurisdiction for the appointment of a successor
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 Eligible Lender Trustee from any obligations otherwise imposed on it
under the Basic Documents until such successor has in fact assumed such
appointment.

     If at any time the Eligible Lender Trustee shall cease to be or shall be
likely to cease to be eligible in accordance with the provisions of Section 10.1
and shall fail to resign after written

                                       19
<PAGE>

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
Counterparties. 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.

     SECTION 10.4  Merger or Consolidation of Eligible Lender Trustee.  Any
                   --------------------------------------------------
corporation

                                       20

it may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Eligible Lender Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the 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 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.

any manner or eliminating any of the provisions in this Agreement or modifying

Agreement and notwithstanding the above, the final distribution on this Excess
Distribution Certificate will be made after due notice by the Administrator of
the pendency of such distribution and only upon presentation and surrender of
this Excess Distribution Certificate at the office or agency maintained for the
purpose by the Eligible Lender Trustee in the Borough of Manhattan, The City of
New York.

     Reference is hereby made to the further provisions of this Excess
Distribution Certificate set forth on the reverse hereof, which further
provisions shall for all purposes have the same effect as if set forth at this
place.

     Unless the certificate of authentication hereon shall have been executed by
an authorized officer of the Eligible Lender Trustee or its authenticating
agent, by manual signature, this Excess Distribution Certificate shall not
entitle the holder hereof to any benefit under the Trust Agreement or the
Administration Agreement or be valid for any purpose.

                 [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

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.
