Ladies and Gentlemen:

            SLM Funding Corporation, a Delaware corporation (the "Company"), and
the Student Loan Marketing Association, a corporation formed under the laws of
the United States ("Sallie Mae"), propose, subject to the terms and conditions
stated herein and in the Underwriting Agreement, dated April 12, 2000 (the
"Underwriting Agreement"), between the Company and Sallie Mae, on the one hand,
J.P. Morgan Securities Inc. and Merrill Lynch, Pierce, Fenner & Smith
Incorporated, on the other hand, that the Company will cause the trust (the

between the Company and Chase Manhattan Bank Delaware, as trustee (the "Eligible
Lender Trustee"), to issue and sell to the Underwriters named in Schedule I

specified in Schedule II hereto (the "Designated Securities"). The Notes will be
issued and secured pursuant to the Indenture, dated as of April 1, 2000 (the
"Indenture"), between the Trust and Bankers Trust Company, as trustee (the
"Indenture Trustee").

            Except as modified pursuant to Schedule II hereto, each of the
provisions of the Underwriting Agreement is incorporated herein by reference in
its entirety, and shall be deemed to be a part of this Agreement to the same
extent as if such provisions had been set forth in full herein; and each of the
representations and warranties set forth therein shall be deemed to have been
made at and as of the date of this Pricing Agreement, except that each
representation and warranty which refers to the Prospectus in Section 2 of the

Underwriting Agreement are used herein as therein defined.

            The Representatives designated to act on behalf of the
Representatives and on behalf of each of the Underwriters of the Designated
Securities pursuant to Section 12 of the Underwriting Agreement and the address
of the Representatives referred to in such Section 12 are set forth at the end
of Schedule II hereto.

            An amendment to the Registration Statement, or a supplement to the
Prospectus, as the case may be, relating to the Designated Securities, in the
form heretofore delivered to you is now proposed to be filed with the
Commission.

            Subject to the terms and conditions set forth herein and in the
Underwriting Agreement incorporated herein by reference, the Company agrees to
cause the Trust to issue and sell to each of the Underwriters, and each of the
Underwriters agrees, severally and not jointly, to purchase from the Trust, at
the time and place and at the purchase price to the Underwriters set forth in
Schedule II hereto, the amount of Designated Securities set forth opposite the
name of such Underwriter in Schedule I hereto, less the amount of Designated
Securities covered by Delayed Delivery Contracts, if any, as may be specified in
Schedule II.

            During the period beginning from the date of this Pricing Agreement
for the Designated Securities and continuing to and including April 26, 2000,
the Company agrees, and Sallie Mae agrees that it will cause the Company, not
to, and not to permit any affiliated entity to, offer, sell, contract to sell or
otherwise dispose of, any securities (other than the Designated Securities)
evidencing an ownership in, or any securities (other than the related Notes)
collateralized by, Student Loans, without the prior written consent of the
Representatives.

            Each Underwriter represents and agrees that (a) it has not offered
or sold and will not offer or sell any Notes or Certificates to persons in the
United Kingdom prior to the expiration of the period of six months from the
issue date of the Notes and the Certificates except to persons whose ordinary
activities involve them in acquiring, holding, managing or disposing of
investments (as principal or agent) for the purposes of their businesses or
otherwise in circumstances which have not resulted and will not result in an
offer to the public in the United Kingdom within the meaning of the Public
Offers of Securities Regulations 1995; (b) it has complied and will comply with
all applicable provisions of the Financial Services Act 1986 with respect to
anything done by it in relation to the Notes and the Certificates in, from or
otherwise involving the United Kingdom; and (c) it has only issued or passed on
and will only issue or pass on in the United Kingdom any document received by it
in connection with the issuance of the Notes and the Certificates to a person
who is of a kind described in article 11(3) of the Financial

sign and return to us 7 counterparts hereof, and upon acceptance hereof by you,
on behalf of each of the Underwriters, this letter and such acceptance hereof,
including the provisions of the Underwriting Agreement incorporated herein by
reference, shall constitute a binding agreement between each of the Underwriters
and the Company and Sallie Mae. It is understood that your acceptance of this
letter on behalf of each of the Underwriters is or will be pursuant to the
authority set forth in a form of Agreement among Underwriters, the form of which
shall be submitted to the Company and Sallie Mae for examination upon request,
but without warranty on the part of the Representatives as to the authority of

                                  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 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


                                       7
<PAGE>

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, 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 Seller 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.


                                       8
<PAGE>

      No successor Interim 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 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 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 shall be eligible pursuant to Section
8.1.

                                  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 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

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


                                       9
<PAGE>

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 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
receipt by the intended recipient or three Business Days after mailing if mailed
by certified mail, postage prepaid (except that notice to the Interim Eligible
Lender Trustee shall be deemed given only upon actual receipt by the Interim
Eligible Lender Trustee), if to the Interim Eligible Lender Trustee, addressed

at such other address as shall be designated by such party in a 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


                                       10
<PAGE>

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.

      SECTION 9.5 Successors and Assigns. All covenants and agreements contained
herein shall be binding upon and to the benefit of, the Seller and its
successors and the Interim Eligible Lender Trustee and its successors, all as
herein provided.

      SECTION 9.6 Headings. The headings of the various Articles and Sections

      SECTION 2.7 Liability of the Certificateholders.

      (a)   Notwithstanding the provisions of Section 3803 of the Delaware

            shall 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
            Certificateholder or the 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 Certificateholder or holder of the Excess Distribution
            Certificate 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.

The Depositor hereby represents, warrants and covenants to the Eligible Lender
Trustee as follows:

      (a)   The Depositor is duly organized and validly existing as a Delaware
            corporation in good standing under the laws of the State of
            Delaware, with power and authority to own its properties and to
            conduct its business as such properties are currently owned and such

            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, agreement or other instrument to which the Depositor is a
            party or by which it is bound; nor result in the creation or
            imposition of any Lien upon any of its properties pursuant to the
            terms of any such indenture, agreement or other instrument (other
            than pursuant to the Basic Documents); nor violate any law or, to
            the Depositor's knowledge, any order, rule or regulation applicable
            to the Depositor of any court or of any Federal or state regulatory
            body, administrative agency or other governmental instrumentality
            having jurisdiction over the Depositor or its properties.


                                       4
<PAGE>

      (e)   The Depositor agrees for the benefit of the Noteholders, the
            Certificateholders 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 Certificate of Incorporation
            and with each of the undertakings set forth in Annex I hereto.

      SECTION 2.10 Intentionally Omitted.

                                   ARTICLE III

                  Trust Certificates and Transfer of Interests;
                         Excess Distribution Certificate

      SECTION 3.1 Initial Beneficial Ownership. Upon the formation of the Trust
by the contribution by the Depositor pursuant to Section 2.5 and until the
issuance of the Trust Certificates, the Depositor shall be the sole beneficial
owner of the Trust.

      SECTION 3.2 The Trust Certificates. The Trust Certificates shall be issued
in denominations of $100,000 or in integral multiples of $1,000 in excess
thereof. The Trust Certificates shall be executed on behalf of the Trust by
manual or facsimile signature of an authorized officer of the Eligible Lender
Trustee. Trust Certificates 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 Trust
Certificates or did not hold such offices at the date of authentication and
delivery of such Trust Certificates.

      SECTION 3.3 Authentication of Trust Certificates. Concurrently with the
sale of the Trust Student Loans to the Trust pursuant to the Purchase Agreement,
the Eligible Lender Trustee shall cause the Trust Certificates in an aggregate
principal amount equal to the Initial Certificate Principal Balance 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, in
authorized denominations. No Trust Certificate shall entitle its holder to any
benefit under this Agreement, or shall be valid for any purpose, unless there
shall appear on such Trust Certificate a certificate of authentication
substantially in the form set forth in Exhibit A, executed by the Eligible
Lender Trustee or The


                                       5
<PAGE>

Chase Manhattan Bank, as the Eligible Lender Trustee's authenticating agent, by
manual signature; such authentication shall constitute conclusive evidence that
such Trust Certificate shall have been duly authenticated and delivered
hereunder. All Trust Certificates shall be dated the date of their
authentication. No further Trust Certificates shall be issued except pursuant to
Section 3.4, 3.5 or 3.12 hereunder.

      SECTION 3.4 Registration of Transfer and Exchange of Trust Certificates.
The Certificate Registrar shall keep or cause to be kept, at the office or
agency maintained pursuant to Section 3.8, a Certificate Register in which,
subject to such reasonable regulations as it may prescribe, the Eligible Lender
Trustee shall provide for the registration of Trust Certificates and of
transfers and exchanges of Trust Certificates as herein provided. The Chase
Manhattan Bank shall be the initial Certificate Registrar.

      Upon surrender for registration of transfer of any Trust Certificate at
the office or agency maintained pursuant to Section 3.8, 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 or transferees, one or more new Trust
Certificates in authorized denominations of a like aggregate amount dated the
date of authentication by the Eligible Lender Trustee or any authenticating
agent. At the option of a Certificateholder, Trust Certificates may be exchanged
for other Trust Certificates of authorized denominations of a like aggregate
amount upon surrender of the Trust Certificates to be exchanged at the office or
agency maintained pursuant to Section 3.8.

      Every Trust 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 Certificate Registrar
duly executed by the Certificateholder 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. Each Trust 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 Trust Certificates, but the Eligible Lender Trustee or the
Certificate Registrar may require payment of a sum sufficient to cover any tax
or governmental charge that


                                       6
<PAGE>

may be imposed in connection with any transfer or exchange of Trust
Certificates.

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

      The Trust Certificates and any beneficial interest in such Trust
Certificates 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) entities whose underlying assets include plan assets by reason of a plan's
investment in such entities (each, a "Benefit Plan"). By accepting and holding a
Trust Certificate or an interest therein, the Certificateholder thereof or
Certificate Owner thereof shall be deemed to have represented and warranted that
it is not a Benefit Plan, is not purchasing Trust Certificates on behalf of a
Benefit Plan and is not using assets of a Plan to purchase any Certificates and
to have agreed that if the Trust Certificate is deemed to be a plan asset, the
Certificateholder will promptly dispose of the Trust Certificate.

      SECTION 3.5 Mutilated, Destroyed, Lost or Stolen Trust Certificates. If
(a) any mutilated Trust Certificate shall be surrendered to the Certificate
Registrar, or if the Certificate Registrar shall receive evidence to its
satisfaction of the destruction, loss or theft of any Trust Certificate, and (b)
there shall be delivered to the 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 Trust
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 Trust Certificate, a new Trust Certificate
of like tenor and denomination. In connection with the issuance of any new Trust
Certificate under this Section, the Eligible Lender Trustee and the 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
Trust Certificate issued pursuant to this Section shall constitute conclusive
evidence of ownership in the Trust, as if originally issued, whether or not the
lost, stolen or destroyed Trust Certificate shall be found at any time.

      SECTION 3.6 Persons Deemed Owners. Prior to due presentation of a Trust
Certificate for registration of transfer, the Eligible Lender Trustee and the
Certificate Registrar and any agent of either of them may treat the Person in
whose name any Trust Certificate shall be registered in the Certificate Register
as the owner of such Trust Certificate for the purpose of receiving
distributions pursuant to Section 5.1 and for all other purposes whatsoever, and
neither the Eligible Lender Trustee, the Certificate Registrar nor any agent
thereof shall be bound by any notice to the contrary.

      SECTION 3.7 Access to List of Certificateholders' Names and Addresses. The
Eligible Lender Trustee shall furnish or cause to be furnished to the Depositor,
within 15 days after receipt by the Eligible Lender Trustee of a request
therefor from the Depositor in writing, a list, in such form as the Depositor
may reasonably require, of the names and addresses of the Certificateholders as
of the most recent Record Date. If three or more Certificateholders or one or
more Certificateholders evidencing not less than 25% of the Certificate
Principal Balance apply in writing to the Eligible Lender Trustee, and such
application states that the applicants desire to communicate with other
Certificateholders with respect to their rights under this Agreement or under
the Trust Certificates and such application is accompanied by a copy of the
communication that such applicants propose to transmit, then the Eligible Lender
Trustee shall, within five Business Days after the receipt of such application,
afford such applicants access during normal business hours to the current list
of Certificateholders. Upon receipt of any such application, the Eligible Lender
Trustee shall promptly notify the Depositor by providing a copy of such
application and a copy of the list of Certificateholders produced in response
thereto. Each Certificateholder, by receiving and holding a Trust Certificate,
shall be deemed to have agreed not to hold any of the Depositor, the Certificate
Registrar or the Eligible Lender Trustee accountable by reason of the disclosure
of its name and address, regardless of the source from which such information
was derived.

      SECTION 3.8 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 Trust Certificates 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 Trust Certificates and the other
Basic Documents may be served. The Eligible Lender Trustee initially designates
1201 Market Street, Wilmington, Delaware, as its principal Corporate Trust
Office. The Eligible Lender Trustee's New York office and its authenticating
agent's office are located at 450 West 33rd Street, 15th Floor, New York,


                                       8

Trustee shall give prompt written notice to the Depositor and to the
Certificateholders of any change in the location of the Certificate Register or
any such office or agency.

      SECTION 3.9 Appointment of Certificate Paying Agent. The Certificate
Paying Agent shall make distributions to Certificateholders from the amounts
received from the Indenture Trustee out of the Trust Accounts pursuant to
Section 5.1 and shall report the amounts of such distributions to the Eligible
Lender Trustee. Any 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 Certificate Paying Agent if the Eligible Lender Trustee
determines in its sole discretion that the Certificate Paying Agent shall have
failed to perform its obligations under this Agreement in any material respect.
The 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 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 Certificate Paying Agent, the Eligible
Lender Trustee shall appoint a successor to act as Certificate Paying Agent
(which shall be a bank or trust company). The Eligible Lender Trustee shall give
notice to the Rating Agencies of the appointment of a successor Certificate
Paying Agent. The Eligible Lender Trustee shall cause such successor Certificate
Paying Agent or any additional Certificate Paying Agent appointed by the
Eligible Lender Trustee to execute and deliver to the Eligible Lender Trustee an
instrument in which such successor Certificate Paying Agent or additional
Certificate Paying Agent shall agree with the Eligible Lender Trustee that as
Certificate Paying Agent, such successor Certificate Paying Agent or additional
Certificate Paying Agent will hold all sums, if any, held by it for payment to
the Certificateholders in trust for the benefit of the Certificateholder
entitled thereto until such sums shall be paid to such Certificateholder. The
Certificate Paying Agent shall return all unclaimed funds to the Eligible Lender
Trustee and upon removal of a Certificate Paying Agent such 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 Certificate Paying Agent, for so
long as the Eligible Lender Trustee shall act as Certificate Paying Agent and,
to the extent applicable, to any


                                       9
<PAGE>

other paying agent appointed hereunder. Any reference in this Agreement to the
Certificate Paying Agent shall include any co-paying agent unless the context
requires otherwise.

      SECTION 3.10 Book-Entry Certificates. The Trust Certificates, upon
original issuance, will be issued in the form of a typewritten Trust Certificate
or Trust Certificates representing Book-Entry Certificates, to be delivered to
The Depository Trust Company, the initial Clearing Agency, by, or on behalf of,
the Trust. Such Book-Entry Certificate or Book-Entry Certificates shall
initially be registered on the Certificate Register in the name of Cede & Co.,
the nominee of the initial Clearing Agency, and no Certificate Owner will
receive a Definitive Certificate representing such Certificate Owner's interest
in such Trust Certificate, except as provided in Section 3.12. Unless and until
definitive, fully registered Trust Certificates (the "Definitive Certificates")
have been issued to Certificate Owners pursuant to Section 3.12:

            (i) the provisions of this Section shall be in full force and
      effect;

            (ii) the Certificate Registrar and the Eligible Lender Trustee shall
      be entitled to deal with the Clearing Agency for all purposes of this
      Agreement (including the payment of principal of and interest on the Trust
      Certificates and the giving of instructions or directions hereunder) as
      the sole Certificateholder and shall have no obligation to the Certificate
      Owners;

            (iii) to the extent that the provisions of this Section conflict
      with any other provisions of this Agreement, the provisions of this
      Section shall control;

            (iv) the rights of Certificate Owners shall be exercised only
      through the Clearing Agency and shall be limited to those established by
      law and agreements between such Certificate Owners and the Clearing Agency
      and/or the Clearing Agency Participants. Pursuant to the Certificate
      Depository Agreement, unless and until Definitive Certificates are issued
      pursuant to Section 3.12, the initial Clearing Agency will make book-entry
      transfers among the Clearing Agency Participants and receive and transmit
      distributions in respect of the Certificate Principal Balance and interest
      on the Trust Certificates to such Clearing Agency Participants; and

            (v) whenever this Agreement requires or permits actions to be taken
      based upon instructions or directions of Certificateholders of Trust
      Certificates evidencing a


                                       10
<PAGE>

      specified percentage of the Certificate Principal Balance, the Clearing
      Agency shall be deemed to represent such percentage only to the extent
      that it has received instructions to such effect from Certificate Owners
      and/or Clearing Agency Participants owning or representing, respectively,
      such required percentage of the beneficial interest in the Trust
      Certificates and has delivered such instructions to the Eligible Lender
      Trustee.

      SECTION 3.11 Notices to Clearing Agency. Whenever a notice or other
communication to the Certificateholders is required under this Agreement, unless
and until Definitive Certificates shall have been issued to Certificate Owners
pursuant to Section 3.12, the Eligible Lender Trustee shall give all such
notices and communications specified herein to be given to Certificateholders to
the Clearing Agency, and shall have no obligations to the Certificate Owners.

      SECTION 3.12 Definitive Certificates. If (i) the Administrator advises the
Eligible Lender Trustee in writing that the Clearing Agency is no longer willing
or able to discharge properly its responsibilities with respect to the Trust
Certificates, and the Administrator is unable to locate a qualified successor,
(ii) the Administrator at its option advises the Eligible Lender Trustee in
writing that it elects to terminate the book-entry system through the Clearing
Agency or (iii) after the occurrence of an Event of Default, a Servicer Default
or an Administrator Default, Certificate Owners representing beneficial
interests aggregating at least a majority of the Certificate Principal Balance
advise the Clearing Agency (which shall then notify the Eligible Lender Trustee)
in writing that the continuation of a book-entry system through the Clearing
Agency is no longer in the best interest of the Certificate Owners, then the
Eligible Lender Trustee shall cause the Clearing Agency to notify all
Certificate Owners of the occurrence of any such event and of the availability
of the Definitive Certificates to Certificate Owners requesting the same. Upon
surrender to the Eligible Lender Trustee of the typewritten Trust Certificate or
Trust Certificates representing the Book-Entry Certificates by the Clearing
Agency, accompanied by registration instructions, the Eligible Lender Trustee
shall execute and authenticate the Definitive Certificates in accordance with
the instructions of the Clearing Agency. Neither the Certificate Registrar nor
the Eligible Lender Trustee shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions. Upon the issuance of Definitive Certificates, the Eligible
Lender Trustee shall recognize the registered holders of the Definitive
Certificates as Certificateholders. The Definitive Certificates shall, at the
expense of the Depositor, be printed, lithographed or engraved


                                       11
<PAGE>

or may be produced in any other manner as is reasonably acceptable to the
Eligible Lender Trustee, as evidenced by its execution thereof.

      SECTION 3.13 The Excess Distribution Certificate.

      (a) General. The Excess Distribution Certificate shall be issued without
denomination. The Excess Distribution Certificate shall receive payments as
provided in Section 2.8C.1(F)(ii) 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 and of transfers and exchanges of


                                       12
<PAGE>

the Excess Distribution Certificate as herein provided. The Chase Manhattan Bank
shall be the initial 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


                                       13
<PAGE>

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.
If (1) the mutilated Excess Distribution Certificate shall be surrendered to the
Excess Distribution Certificate Registrar, or if the Excess Distribution
Certificate Registrar shall receive 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


                                       14
<PAGE>

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 Section 2.8C.1F(ii) 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

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.

                Authority and Duties of Eligible Lender Trustee

      SECTION 6.1 General Authority. The Eligible Lender Trustee is authorized
and directed to execute and deliver the Basic Documents to which the Trust is to
be a party and each certificate or other document attached as an exhibit to or
contemplated by the Basic Documents to which the Trust is to be a party, in each
case, in such form as the Depositor shall approve as evidenced conclusively by
the Eligible Lender Trustee's execution thereof, and, on behalf of the Trust, to
direct the Indenture Trustee to authenticate and deliver Notes in the aggregate
principal amount of $2,474,750,000. The Eligible Lender Trustee is also
authorized and directed on behalf of the Trust (i) to acquire and hold legal
title to the Trust Student Loans from the Depositor and (ii) to take all actions
required pursuant to Section 3.2C of the Administration Agreement and otherwise
follow the direction of and cooperate with the Servicer in submitting, pursuing

Interest Subsidy Payments and Special Allowance Payments relating to the Trust
Student Loans.

      In addition to the foregoing, the Eligible Lender Trustee is authorized to
take all actions required of the Trust pursuant to the Basic Documents. The
Eligible Lender Trustee is further authorized from time to time to take such
action as the Administrator directs or instructs with respect to the Basic
Documents and is directed to take such action to the extent that the
Administrator is expressly required pursuant to the Basic Documents to cause the
Eligible Lender Trustee to act.

      SECTION 6.2 General Duties. It shall be the duty of the Eligible Lender
Trustee to discharge (or cause to be discharged) all its responsibilities
pursuant to the terms of this Agreement, the other Basic Documents to which the
Trust is a party and to administer the Trust in the interest of the
Certificateholders, and the holder of the Excess Distribution Certificate
subject to and in accordance with the provisions of this Agreement and the other
Basic Documents. Without limiting the foregoing, the Eligible Lender Trustee
shall on behalf of the Trust file and prove any claim or claims that may exist
on behalf of the Trust against the Depositor in connection with any claims
paying procedure as part of an insolvency or a receivership proceeding involving
the Depositor. Notwithstanding the foregoing, the Eligible Lender Trustee shall
be deemed to have discharged its duties and responsibilities hereunder and under
the other Basic Documents to the extent the Administrator has agreed in the
Administration Agreement to perform and act or to discharge any


                                       21
<PAGE>

duty of the Eligible Lender 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 expressly provided in the Basic Documents,
the Eligible Lender Trustee shall have no obligation to administer, service or
collect the Trust Student Loans or to maintain, monitor or otherwise supervise
the administration, servicing or collection of the Trust Student Loans.

      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 Certificateholders 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 Certificateholders 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 Certificateholders, 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


                                       22
<PAGE>

            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 Certificateholders 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 Certificateholders, and shall have no
            liability to any Person for such action or inaction.

      SECTION 6.4 No Duties Except as Specified in this Agreement or in
Instructions. The Eligible Lender Trustee shall not have any duty or obligation
to manage, make any payment with respect to, register, record, sell, service,
dispose of or otherwise deal with the Trust Estate, or to otherwise take or
refrain from taking any action under, or in connection with, any document
contemplated hereby to which the Eligible Lender Trustee is a party, except as
expressly provided by the terms of this Agreement or in any document or written
instruction received by the Eligible Lender Trustee pursuant to Section 6.3; and
no implied duties or obligations shall be read into this Agreement or any other
Basic Document against the Eligible Lender Trustee. The Eligible Lender Trustee
shall have no responsibility for filing any financing or continuation statement
in any public office at any time or to otherwise perfect or maintain the
perfection of any security interest or lien granted to it hereunder or to
prepare or file any Commission filing for the Trust or to record this Agreement
or any other Basic Document. The Eligible Lender Trustee nevertheless agrees
that it will, at its own cost and expense, promptly take all action as may be
necessary to discharge any Liens on any part of the Trust Estate that result
from actions by, or claims against, Chase Manhattan Bank Delaware in its
individual capacity or as the Eligible

tax purposes. The Certificateholders shall not direct the Eligible Lender
Trustee to take action that would violate the provisions of this Section.

            accounting or to take any action or proceeding in any court for a
            partition or winding up of all or any part of the Trust or Trust
            Estate nor (z) otherwise affect the rights, obligations and
            liabilities of the parties hereto.

      (b)   Except as provided in Section 9.1(a), neither the Depositor nor any
            Certificateholder shall be entitled to revoke or terminate the
            Trust.

      (c)   Notice of any termination of the Trust, specifying the Distribution
            Date upon which the Certificateholders shall surrender their Trust
            Certificates to the Certificate Paying Agent for payment of the
            final distribution and cancellation, shall be given promptly by the
            Eligible Lender Trustee by letter to Certificateholders mailed
            within five Business Days of receipt of notice of such termination
            from the Administrator given pursuant to Section 6.1C of the
            Administration Agreement, stating (i) the Distribution Date upon
            which final payment of the Trust Certificates shall be made upon
            presentation and surrender of the Trust Certificates at the office
            of the Certificate Paying Agent therein designated, (ii) the amount
            of any such final payment and (iii) that the Record Date otherwise
            applicable to such Distribution Date is not applicable, payments
            being made only upon presentation and surrender of the Trust
            Certificates at the office of the Certificate Paying Agent therein
            specified. The Eligible Lender Trustee shall give such notice to the
            Certificate Registrar (if other than the Eligible Lender Trustee)
            and the Certificate Paying Agent at the time such notice is given to
            Certificateholders. Upon presentation and surrender of the Trust
            Certificates, the Certificate Paying Agent shall cause to be
            distributed to Certificateholders amounts distributable on such
            Distribution Date pursuant to Section 5.1.

      In the event that all the Certificateholders shall not surrender their
Trust Certificates for cancellation within six months after the date specified
in the above mentioned written notice, the Eligible Lender Trustee shall give a
second written notice to the remaining Certificateholders to surrender their
Trust Certificates for cancellation and receive the final distribution with
respect thereto. If within one year after the second notice all the Trust
Certificates shall not have been surrendered for cancellation, the Eligible
Lender Trustee may take appropriate steps, or may appoint an agent to take
appropriate steps, to contact the remaining Certificateholders concerning
surrender of their Trust Certificates, and the cost thereof shall be paid out of
the funds and other assets that shall remain subject to this Agreement. Any
funds remaining in the Trust after exhaustion of such remedies and no later than
five years after the first such notice shall be distributed by the Eligible
Lender Trustee to the Depositor.

      Upon final distribution of any funds remaining in the Trust, the Eligible
Lender Trustee shall file a certificate of cancellation of the Trust's
certificate of trust pursuant to Section 3810(c) of the Delaware Business Trust
Act.

      SECTION 9.2 Dissolution upon Insolvency of the Depositor. Notwithstanding
the provisions of Section 3808 of the Delaware Business Trust Act, in the event
that an Insolvency Event shall occur with respect to the Depositor, (x) the
Trust created hereunder shall dissolve and (y) this Agreement shall be
terminated in accordance with Section 9.1 90 days after the date of such
Insolvency Event. Promptly after the occurrence of any Insolvency Event with
respect to the Depositor, (i) the Depositor shall give the Indenture Trustee,
the Eligible Lender Trustee, any Swap Counterparties, and each Rating Agency
written notice of such Insolvency Event, and (ii) the Eligible Lender Trustee
shall, upon the receipt of such written notice from the Depositor, give prompt
written notice to the Certificateholders and the Indenture Trustee, of the
occurrence of such event and of the effect of such event under this Section 9.2;
provided, however, that any failure to give a notice required by this sentence
shall not prevent or delay, in any manner, a termination of the Trust pursuant
to the first sentence of this Section 9.2. Upon a termination of the Trust
pursuant to this Section, the Eligible Lender Trustee shall direct the Indenture
Trustee promptly to sell the assets of the Trust (other than the Trust Accounts)
in a commercially reasonable manner and on commercially reasonable terms. The
proceeds of such a sale of the assets of the Trust shall be treated as
collections under the Administration Agreement.

                     Successor Eligible Lender Trustees and
                       Additional Eligible Lender Trustees

      SECTION 10.1 Eligibility Requirements for Eligible Lender Trustee. The
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 Trust
Student Loans on behalf of the Trust, with a valid lender identification number
with respect to the Trust Student Loans from the Department; (ii) being
authorized to exercise corporate trust powers and hold legal title to the Trust
Student Loans; (iii) having in effect Guarantee Agreements with each of the
Guarantors; (iv) having a combined capital and surplus of at least $50,000,000
and being subject to supervision or examination by Federal or state authorities;
(v) having its principal place of business in the State of Delaware and
otherwise complying with Section 3807 of the Delaware Business Trust Act; and
(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 or the Certificates). 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 provisions of this Section, the Eligible Lender Trustee shall resign
immediately in the manner and with the effect specified in Section 10.2.

      SECTION 10.2 Resignation or Removal of Eligible Lender Trustee. 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


                                       32
<PAGE>

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 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


                                       33
<PAGE>

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 all Certificateholders, 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 into which the Eligible Lender Trustee may be merged or converted or
with which 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


                                       34
<PAGE>

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

            (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


                                       35
<PAGE>

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.

                                  ARTICLE XI

                                 Miscellaneous

      SECTION 11.1 Supplements and Amendments. This Agreement may be amended by
the Depositor and the Eligible Lender Trustee, with prior written notice to the
Rating Agencies, without the consent of any of the Noteholders, the
Certificateholders or the Swap Counterparties, 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 modifying in any manner the rights of the Noteholders, the
Certificateholders or the Swap Counterparties; 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, Certificateholder or any Swap
Counterparty.

      This Agreement may also be amended from time to time by the Depositor and
the 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 Principal
Balance, for the purpose of adding any


                                       36
<PAGE>

provisions to or changing in any manner or eliminating any of the provisions of
this Agreement or 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 Principal Balance required to consent to any such amendment,
without the consent of all the outstanding Noteholders and Certificateholders.

      This Agreement may also be amended from time to time by the Depositor and
the Eligible Lender Trustee, with prior written notice to the Rating Agencies,
with the consent of the affected Swap Counterparty for the purpose of adding any
provisions to, changing in any manner, or eliminating any of the provisions of
this Agreement or modifying in any manner the rights of a Swap Counterparty if
in the Opinion of Counsel such amendment materially adversely affects the
interests of such Swap Counterparty.

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

      It shall not be necessary for the consent of Certificateholders, the
Noteholders, the Indenture Trustee or any Swap Counterparty 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 Eligible Lender Trustee may
prescribe.

      Prior to the execution of any amendment to this Agreement, the 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 Eligible Lender Trustee may, but shall not be obligated to, enter
into any such amendment which affects the Eligible Lender Trustee's own rights,
duties or immunities under this Agreement or otherwise.

      SECTION 11.2 No Legal Title to Trust Estate in Certificateholders. Neither
the Certificateholders nor the holder of the Excess Distribution Certificate
shall have legal title to any part of the Trust Estate. The Certificateholders
shall be entitled to receive distributions with respect to their undivided
beneficial ownership interest therein only in accordance with Articles V and IX.
The holder of the Excess Distribution Certificate shall be entitled to receive
distributions with respect to its undivided beneficial ownership interest
therein only in accordance with Section 3.13 of this Agreement. No transfer, by
operation of law or otherwise, of any right, title, or interest of the
Certificateholders or of the holder of the Excess Distribution Certificate to

terminate this Agreement or the trusts hereunder or entitle any transferee to an
accounting or to the transfer to it of legal title to any part of the Trust
Estate.

Swap Counterparties, and nothing in this Agreement (other than Section 2.7),

respect of this Agreement or any covenants, conditions or provisions contained
herein.

            Any notice so mailed within the time prescribed in this Agreement
            shall be conclusively presumed to have been duly given, whether or
            not the Certificateholder receives such notice.

      SECTION 11.5 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

unenforceable such provision in any other jurisdiction.

      SECTION 11.6 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.

      SECTION 11.7 Successors and Assigns. All covenants and agreements
contained herein shall be binding upon to the benefit of, the Depositor and its
successors, the Eligible Lender Trustee and its successors, each
Certificateholder and its successors and permitted assigns, each holder of the

            each Certificateholder by accepting a Trust Certificate, the holder
            of the Excess Distribution Certificate by accepting the Excess

      THIS CERTIFIES THAT Cede & Co. is the registered owner of $_____________
non-assessable, fully-paid, fractional undivided interest in the SLM Student
Loan Trust 2000-3 (the "Trust"), a trust formed under the laws of the State of
Delaware by SLM Funding Corporation, a Delaware corporation (the "Depositor").
The Trust was created pursuant to a Trust Agreement dated as of April 1, 2000
(the "Trust Agreement"), between the Depositor and Chase Manhattan Bank
Delaware, a Delaware banking corporation, not in its individual capacity but
solely as eligible lender trustee on behalf of the Trust (the "Eligible Lender
Trustee"), a summary of certain of the pertinent provisions of which is set
forth below. To the extent not otherwise defined herein, the capitalized terms
used herein have the meanings assigned to them in Appendix A to the Trust
Agreement.

      This Certificate is one of the duly authorized Certificates designated as
"Floating Rate Student Loan- Backed Certificates" (herein called the "Trust
Certificates"). This Trust Certificate is issued under and is subject to the
terms, provisions and conditions of the Trust Agreement, to which Trust
Agreement the holder of this Trust Certificate by virtue of the acceptance
hereof assents and by which such holder is bound. The property of the Trust
includes a pool of student loans (the "Trust Student Loans"), all moneys paid
thereunder on or after March 27, 2000, certain bank accounts and the proceeds
thereof and certain other rights under the Trust Agreement, the Sale Agreement,
the Purchase Agreement, the Administration Agreement and the Servicing Agreement
and all proceeds of the foregoing. The rights of the holders of the Trust
Certificates to the assets of the Trust are subordinated to the rights of the
holders of the Notes issued under the Indenture dated as of April 1, 2000,
between the Trust and Bankers Trust Company, as Indenture Trustee, and
designated as "Floating Rate Student Loan-Backed Notes" (the "Notes"), as set
forth in the Trust Agreement, the Indenture and the Administration Agreement.

      Under the Trust Agreement, to the extent of funds available therefor,
interest on the Certificate Principal Balance of this Trust Certificate at the
Certificate Rate (as defined below) will be distributed on the 25th day of each
January, April, July and October (or, if such 25th


                                       2
<PAGE>

day is not a Business Day, the next succeeding Business Day) (each a
"Distribution Date"), commencing on October 25, 2000, to the person in whose
name this Trust Certificate is registered as of the close of business on the day
immediately preceding the Distribution Date (such day the "Record Date"), in
each case to the extent of such Certificateholder's pro rata interest in the
amount or amounts to be distributed to Certificateholders on such Distribution
Date pursuant to the Administration Agreement.

      The Certificate Rate for each Accrual Period shall be equal to Three-Month
LIBOR, except for the first Accrual Period, which shall be Six-Month LIBOR, on
the second business day before the beginning of that Accrual Period plus 0.55%
per annum.

      Each holder of this Trust Certificate acknowledges and agrees that its
rights to receive distributions in respect of this Trust Certificate from
Available Funds and amounts on deposit in the Reserve Account are subordinated
to the rights of the Noteholders as described in the Trust Agreement, the
Indenture and the Administration Agreement.

      It is the intent of the Depositor, the Certificateholders and the
Certificate Owners that, for purposes of Federal, state and local income and
franchise and any other income taxes, the Certificates will be treated as
newly-issued debt. The Depositor and the other Certificateholders by acceptance
of a Trust Certificate (and the Certificate Owners by acceptance of a beneficial
interest in a Trust Certificate), agree to treat, and to take no action
inconsistent with the treatment of, the Trust Certificates for such tax purposes
as newly-issued debt.

      Each Certificateholder or Certificate Owner, by its acceptance of a Trust
Certificate or, in the case of a Certificate Owner, a beneficial interest in a
Trust Certificate, covenants and agrees that such Certificateholder or
Certificate Owner, as the case may be, will not at any time institute against
the Depositor or the Trust, or join in any institution against the Depositor or
the Trust of, any bankruptcy, reorganization, arrangement, insolvency,
receivership or


                                       3
<PAGE>

liquidation proceedings, or other proceedings under any United States Federal
or state bankruptcy or similar law in connection with any obligations relating
to the Trust Certificates, the Notes, the Trust Agreement or any of the other
Basic Documents.

      Distributions on this Trust Certificate will be made as provided in the
Trust Agreement by the Eligible Lender Trustee by wire transfer or by check
mailed to the Certificateholder of record in the Certificate Register without
the presentation or surrender of this Trust Certificate or the making of any
notation hereon, except that with respect to Trust Certificates registered on
the Record Date in the name of the nominee of the Clearing Agency, unless
Definitive Certificates have been issued (initially, such nominee to be Cede &
Co.), payments will be made by wire transfer in immediately available funds to
the account designated by such nominee. Except as otherwise provided in the
Trust Agreement and notwithstanding the above, the final distribution on this
Trust Certificate will be made after due notice by the Eligible Lender Trustee
of the pendency of such distribution and only upon presentation and surrender of
this Trust 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 Trust
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 Trust 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 Trust Certificate]

      The Trust Certificates do not represent an obligation of, or an interest
in, the Depositor, Sallie Mae Servicing Corporation, 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 Trust 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 Trust Agreement. A copy of each of the Trust
Agreement, the Sale Agreement, the Purchase Agreement, the Administration
Agreement, 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 any Certificateholder 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 Certificateholders under the Trust Agreement at
any time by the Depositor and the Eligible Lender Trustee with the consent of
the holders of the Notes and the Trust Certificates each voting as a class
evidencing not less than a majority of the outstanding principal balance of the
Notes and the Certificate Principal Balance. Any such consent by the holder of
this Trust Certificate shall be conclusive and binding on such holder and on all
future holders of this Certificate and of any Trust Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Trust Certificate. The Trust Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the holders of any of the Trust Certificates.


                                       7

      As provided in the Trust Agreement and subject to certain limitations
therein set forth, the transfer of the Trust Certificates is registerable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies maintained by Chase Manhattan Bank Delaware
in its capacity as Certificate Registrar, or by any successor 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 Certificate Registrar duly executed by the holder hereof or such
holder's attorney duly authorized in writing, and thereupon one or more new
Trust Certificates of authorized denominations evidencing the same aggregate
interest in the Trust will be issued to the designated transferee.

      The Trust Certificates are issuable only as registered Trust Certificates
without coupons in denominations of $100,000 or in integral multiples of $1,000
in excess thereof. As provided in the Trust Agreement and subject to certain
limitations therein set forth, Trust Certificates are exchangeable for new Trust
Certificates of authorized denominations evidencing the same aggregate
denomination, 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 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 Certificate Registrar may treat the person in
whose name this Trust Certificate is registered as the owner hereof for all
purposes, and none of the Eligible Lender Trustee or the Certificate Registrar
or any such agent shall be affected by any notice to the contrary.

      The Trust Certificates (including any beneficial interests therein) 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


                                       8
<PAGE>

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
Trust Certificate, the Holder hereof shall be deemed to have represented and
warranted that it is not a Benefit Plan, it is not purchasing this Trust
Certificate on behalf of a Benefit Plan, is not using assets of a Benefit Plan
to purchase this Trust Certificate and to have agreed that if this Trust
Certificate is deemed to be a plan asset, the Holder will promptly dispose of
this Trust Certificate.

      The obligations and responsibilities created by the Trust Agreement and
the Trust created thereby shall terminate upon the payment to Certificateholders
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, and such
purchase of the Trust Student Loans and other property of the Trust will effect
early retirement of the Trust Certificates; 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 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 Trust 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.

                  [Reverse of Excess Distribution Certificate]

      This Excess Distribution Certificate does not represent an obligation of,
or an interest in, the Depositor, Sallie Mae Servicing Corporation, 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 Certificateholders under the Trust Agreement at
any time by the Depositor and the Eligible Lender Trustee with the consent of
the holders of the Notes and the Certificates each voting as a class evidencing
not less than a majority of the outstanding principal balance of the Notes and
the Certificate Principal Balance. The Trust Agreement also permits the
amendment thereof, in certain limited circumstances, without the consent of the
holders of any of the Certificates.

      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 Delaware in its


                                       7

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.

      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


                                       8
<PAGE>

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 Certificateholders
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 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.

                             TO THE TRUST AGREEMENT
                            DATED AS OF APRIL 1, 2000
                        BETWEEN SLM FUNDING CORPORATION,
                                AS DEPOSITOR, AND
                         CHASE MANHATTAN BANK DELAWARE,
                           AS ELIGIBLE LENDER TRUSTEE

      All defined terms are used herein as defined in the Trust Agreement
referred to above.

      Existence. The Depositor will maintain its corporate existence and its
good standing under the laws of the State of Delaware.

      Procedures Observed. The Depositor will observe all corporate procedures
required by its Certificate of Incorporation, its by-laws and the corporation
law of the State of Delaware.

      Management. The business and affairs of the Depositor will be managed by
or under the direction of the Depositor's Board of Directors. The Depositor will
at all times ensure that its Board of Directors duly authorizes all corporate
actions requiring Board authorization. When necessary, the Depositor will obtain
proper authorization from its stockholder for corporate action. Its stockholder
will not be actively involved in the day-to-day management of the Depositor
except as contemplated by an arm's length management services contract.

      Records. The Depositor will maintain separate corporate records and books
of account from those of its stockholder or any other affiliate of its
stockholder. The Depositor will keep correct and complete books and records of
account and minutes of the meetings and other proceedings of its stockholder and
Board of Directors. The resolutions, agreements and other instruments underlying
the transactions contemplated by the Trust Agreement will be continuously
maintained as official records by the Depositor.

      Offices. The Depositor will have an address and telephone number
distinguishable from those of its stockholder. To the extent the Depositor's
office is located in the office of its stockholder or any affiliate of its
stockholder, the Depositor will pay fair market rent for any such office space
and a fair share of any material overhead costs.


                                        1
<PAGE>

      Identifiable Assets. Except in connection with the customary operation of
such cash management system as its stockholder may from time to time in the
ordinary course of business implement for itself and its consolidated
subsidiaries (which cash management system will be operated such that all
transfers of funds are properly documented and the respective assets and
liabilities of the Depositor and its stockholder are ascertainable at all
times), the Depositor's funds and other assets will be identifiable and will not
be commingled with those of its stockholder or any other entity. The Depositor
will maintain separate banking records and books of account from those of its
stockholder or any other affiliate of its stockholder.

      Capitalization. The Depositor will not engage in any business for which
its capitalization would not be adequate.

      Expenses. The Depositor will pay from its own funds and assets all
obligations and indebtedness incurred by it and will provide for its own
material operating expenses and liabilities from its own funds. General overhead
and administrative expenses of its stockholder will not be charged or otherwise
allocated to the Depositor (unless directly attributable to services provided to
or for the account of the Depositor) and such expenses of the Depositor which
are material will not be charged or otherwise allocated to its stockholder. Any
organizational expenses of the Depositor and expenses relating to the
preparation, negotiation, execution and delivery of the Transaction Documents
paid by its stockholder will be charged back to the Depositor. Such expenses
will be paid by the Depositor from amounts available to it as a result of the
capital contributions made by its stockholder, from the yield earned by it on
its Certificates, or from the retained portion of Deferred Payments made to it
under the Sale Agreement.

      Conduct. The Depositor will conduct its business solely in its own name so
as not to mislead others as to the identity of the Depositor. Without limiting
the generality of the foregoing, all oral and written communications related to
the Depositor, including without limitation letters, invoices, purchase orders,
contracts, statements and applications, will be made solely in the name of the
Depositor except for items pursuant to the Facilities and Services Agreement
between the Depositor and its stockholder. The Depositor will utilize its own
separate stationery.


                                        2
<PAGE>

      Inter-company Claims. The Depositor will not enter into any guarantees
made by its stockholder with respect to obligations of the Depositor and the
Depositor will make no guarantees with respect to obligations of its
stockholder. There will be no inter-company debt or claims between the Depositor
and its stockholder other than (i) the obligation of the Depositor to pay to its
stockholder the Deferred Payment under the Purchase Agreement, (ii) the demand
note of its stockholder contributed to the Depositor as part of the Depositor's
capitalization, (iii) such inter-company claims as may arise in connection with
the management services contract referred to above, including a cash management
system for its stockholder and its consolidated subsidiaries as described above,
and (iv) such amounts as may temporarily be carried in inter-company accounts
relating to expenses incurred by its stockholder or its affiliates, to the
extent the Depositor is properly obligated to reimburse its stockholder or any
such affiliate for amounts allocable to the Depositor. The demand note referred
to above will be properly documented on the books and records of the Depositor.

      Reliance by Others. The Depositor will act solely in its name and through
its duly authorized officers or agents in the conduct of its businesses. The
Depositor will not: (a) hold itself out as having agreed to pay or become liable
for the debts of its stockholder; (b) fail to correct any known
misrepresentation with respect to the foregoing; (c) operate or purport to
operate as an integrated, single economic unit with respect to its stockholder
or in its dealings with any other affiliated or unaffiliated entity; (d) seek or
obtain credit or incur any obligation to any third party based upon the assets
of its stockholder or any other affiliated or unaffiliated entity; or (e) induce
any such third party to reasonably rely on the creditworthiness of its
stockholder or any other affiliated or unaffiliated entity for the payment or
performance of the Depositor.

      Arm's Length. The Depositor will maintain an arm's length relationship
between the Depositor and its stockholder and between the Depositor and any
affiliates of its stockholder.

      Disclosure of the Transactions. The annual financial statements of the
Depositor will disclose the effects of the Transactions in accordance with
generally accepted accounting principles. The transfer of the Loans by its
stockholder to the Depositor pursuant to the


                                       3
<PAGE>

Purchase Agreement will be treated as a purchase by the Depositor under
generally accepted accounting principles. In particular, the financial
statements of the Depositor will clearly indicate its existence separate from
its stockholder and will reflect its separate assets and liabilities. None of
such financial statements, nor any consolidated financial statements for its
stockholder, will suggest in any way that the assets of the Depositor are
available to pay the claims of creditors of its stockholder or any other entity.
Any consolidated financial statements of its stockholder and its subsidiaries
prepared for the benefit of third parties will disclose, through appropriate
footnotes or otherwise, the separate corporate existence of the Depositor.

                                   Article II

                                    The Notes

            SECTION 2.1 Form. The Notes, together with the Indenture Trustee's
certificate of authentication, shall be in substantially the form set forth in
Exhibit A, with such appropriate insertions, omissions, substitutions and other
variations as are required or permitted by this Indenture and may have such
letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may, consistently herewith, be determined by the
officers executing the Notes, as evidenced by their execution of the Notes. Any
portion of the text of any Note may be set forth on the reverse thereof, with an
appropriate reference thereto on the face of the Note.

            The Definitive Notes shall be typewritten, printed, lithographed or
engraved or produced by any combination of these methods (with or without steel
engraved borders), all as determined by the officers executing such Notes, as
evidenced by their execution of such Notes.

            Each Note shall be dated the date of its authentication. The terms
of the Notes set forth in Exhibit A are part of the terms of this Indenture.

            SECTION 2.2 Execution, Authentication and Delivery. The Notes shall
be executed on behalf of the Issuer by any of its Authorized Officers. The
signature of any such Authorized Officer on the Notes may be manual or
facsimile.

            Notes bearing the manual or facsimile signature of individuals who
were at any time Authorized Officers of the Issuer shall bind the Issuer,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Notes or did not hold
such offices at the date of such Notes.

            The Indenture Trustee shall upon Issuer Order authenticate and
deliver Notes for original issue in an aggregate principal amount of
$2,474,750,000. The aggregate principal amount of Notes outstanding at any time
may not exceed such amount except as provided in Section 2.5.


                                       4
<PAGE>

            Each Note shall be dated the date of its authentication. The Notes
shall be issuable as registered Notes in the minimum denomination of $1,000 and
in integral multiples of $1,000 in excess thereof.

            No Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears on such Note a
certificate of authentication substantially in the form provided for herein
executed by the Indenture Trustee by the manual signature of one of its
authorized signatories, and such certificate upon any Note shall be conclusive
evidence, and the only evidence, that such Note has been duly authenticated and
delivered hereunder.

            SECTION 2.3 Temporary Notes. Pending the preparation of Definitive
Notes, the Issuer may execute, and upon receipt of an Issuer Order the Indenture
Trustee shall authenticate and deliver, temporary Notes which are printed,
lithographed, typewritten, mimeographed or otherwise produced, of the tenor of
the Definitive Notes in lieu of which they are issued and with such variations
not inconsistent with the terms of this Indenture determined to be appropriate
by the Responsible Officer of the Issuer executing the temporary Notes, as
evidenced by his or her execution of such temporary Notes.

            If temporary Notes are issued, the Issuer will cause Definitive
Notes to be prepared without unreasonable delay. After the preparation of
Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes
upon surrender of the temporary Notes at the office or agency of the Issuer to
be maintained as provided in Section 3.2, without charge to the Noteholder. Upon
surrender for cancellation of any one or more temporary Notes, the Issuer shall
execute and the Indenture Trustee shall authenticate and deliver in exchange
therefor a like principal amount of Definitive Notes of authorized
denominations. Until so exchanged, the temporary Notes shall in all respects be
entitled to the same benefits under this Indenture as Definitive Notes.

            SECTION 2.4 Registration; Registration of Transfer and Exchange. The
Issuer shall cause to be kept a register (the "Note Register") in which, subject
to such reasonable regulations as it may prescribe, the Issuer shall provide for
the registration of Notes and the registration of transfers of Notes. The
Indenture Trustee shall be "Note Registrar" for the purpose of registering Notes
and transfers of Notes as herein provided. Upon any resignation of any Note
Registrar, the Issuer shall promptly


                                       5
<PAGE>

appoint a successor or, if it elects not to make such an appointment, assume the
duties of Note Registrar.

            If a Person other than the Indenture Trustee is appointed by the
Issuer as Note Registrar, the Issuer shall give the Indenture Trustee prompt
written notice of the appointment of such Note Registrar and of the location,
and any change in the location, of the Note Register, and the Indenture Trustee
shall have the right to inspect the Note Register at all reasonable times and to
obtain copies thereof, and the Indenture Trustee shall have the right to rely
upon a certificate executed on behalf of the Note Registrar by an Executive
Officer thereof as to the names and addresses of the Noteholders and the
principal amounts and number of such Notes.

            Upon surrender for registration of transfer of any Note at the
office or agency of the Issuer to be maintained as provided in Section 3.2, if
the requirements of Section 8-401(1) of the UCC are met, the Issuer shall
execute, and the Indenture Trustee shall authenticate and the Noteholder shall
obtain from the Indenture Trustee, in the name of the designated transferee or
transferees, one or more new Notes in any authorized denominations and a like
aggregate principal amount.

            At the option of the Noteholder, Notes may be exchanged for other
Notes in any authorized denominations and a like aggregate principal amount,
upon surrender of the Notes to be exchanged at such office or agency. Whenever
any Notes are so surrendered for exchange, the Issuer shall execute, and the
Indenture Trustee shall authenticate and the Noteholder shall obtain from the
Indenture Trustee, the Notes which the Noteholder making the exchange is
entitled to receive.

            All Notes issued upon any registration of transfer or exchange of
Notes shall be the valid obligations of the Issuer, evidencing the same debt,
and entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

            Every Note presented or surrendered for registration of transfer or
exchange shall be duly endorsed by, or be accompanied by a written instrument of
transfer in form satisfactory to the Indenture Trustee duly executed by the
Noteholder thereof or such Noteholder's attorney duly authorized in writing,
with such signature guaranteed by an "eligible guarantor institution" meeting
the requirements of the Note Registrar, which requirements include membership or
participation in Securities


                                       6
<PAGE>

Transfer Agent's Medallion Program ("STAMP") or such other "signature guarantee
program" as may be determined by the Note Registrar in addition to, or in
substitution for, STAMP, all in accordance with the Exchange Act.

            No service charge shall be made to a Noteholder for any registration
of transfer or exchange of Notes, but the Indenture Trustee may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration of transfer or exchange of Notes,
other than exchanges pursuant to Section 2.3 or 9.6 not involving any transfer.

            The preceding provisions of this Section notwithstanding, the Issuer
shall not be required to make and the Note Registrar need not register transfers
or exchanges of Notes selected for redemption or of any Note for a period of 15
days preceding the due date for any payment with respect to the Note.

            SECTION 2.5 Mutilated, Destroyed, Lost or Stolen Notes. If (i) any
mutilated Note is surrendered to the Indenture Trustee, or the Indenture Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any
Note, and (ii) there is delivered to the Issuer and the Indenture Trustee such
security or indemnity as may be required by each of them to hold the Issuer and
the Indenture Trustee harmless, then, in the absence of notice to the Issuer,
the Note Registrar or the Indenture Trustee that such Note has been acquired by
a bona fide purchaser, and provided that the requirements of Section 8-405 of
the UCC are met, the Issuer shall execute and upon its request the Indenture
Trustee shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Note, a replacement Note; provided,
however, that if any such destroyed, lost or stolen Note, but not a mutilated
Note, shall have become or within 15 days shall be due and payable, or shall
have been called for redemption, instead of issuing a replacement Note, the
Issuer may pay such destroyed, lost or stolen Note when so due or payable or
upon the Redemption Date without surrender thereof. If, after the delivery of
such replacement Note or payment of a destroyed, lost or stolen Note pursuant to
the proviso to the preceding sentence, a bona fide purchaser of the original
Note in lieu of which such replacement Note was issued presents for payment such
original Note, the Issuer and the Indenture Trustee shall be entitled to recover
such replacement Note (or such payment) from the Person to whom it was delivered
or any Person taking such replacement Note from such Person to whom such
replacement Note was delivered or any assignee of such Person, except a bona
fide purchaser, and shall be entitled to recover upon the


                                       7
<PAGE>

security or indemnity provided therefor to the extent of any loss, damage, cost
or expense incurred by the Issuer or the Indenture Trustee in connection
therewith.

            Upon the issuance of any replacement Note under this Section, the
Issuer may require the payment by the Noteholder thereof of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other reasonable expenses (including the fees and expenses of
the Indenture Trustee) connected therewith.

            Every replacement Note issued pursuant to this Section in
replacement of any mutilated, destroyed, lost or stolen Note shall constitute an
original additional contractual obligation of the Issuer, whether or not the
mutilated, destroyed, lost or stolen Note shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Notes duly issued hereunder.

            The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes.

            SECTION 2.6 Persons Deemed Owner. Prior to due presentment for
registration of transfer of any Note, the Issuer, the Indenture Trustee and any
agent of the Issuer or the Indenture Trustee may treat the Person in whose name
any Note is registered (as of the day of determination) as the owner of such
Note for the purpose of receiving payments of principal of, interest, if any, on
such Note and for all other purposes whatsoever, whether or not such Note be
overdue, and neither the Issuer, the Indenture Trustee nor any agent of the
Issuer or the Indenture Trustee shall be affected by notice to the contrary.

            SECTION 2.7 Payment of Principal and Interest; Note Interest
Shortfall. (a) The Notes shall accrue interest as provided in the forms of Notes
set forth in Exhibit A, and such interest shall be payable on each Distribution
Date as specified therein, subject to Section 3.1. Any installment of interest
or principal, if any, payable on any Note which is punctually paid or duly
provided for by the Issuer on the applicable Distribution Date shall be paid to
the Person in whose name such Note (or one or more Predecessor Notes) is
registered on the Record Date by check mailed first-class, postage prepaid to
such Person's address as it appears on


                                       8
<PAGE>

the Note Register on such Record Date, except that, unless Definitive Notes have
been issued pursuant to Section 2.12, with respect to Notes registered on the
Record Date in the name of the nominee of the Clearing Agency (initially, such
nominee to be Cede & Co.), payment shall be made by wire transfer in immediately
available funds to the account designated by such nominee and except for the
final installment of principal payable with respect to such Note on a
Distribution Date or on the Note Final Maturity Date for such Note which shall
be payable as provided below. The funds represented by any such checks returned
undelivered shall be held in accordance with Section 3.3.

      (b) The principal of each Note shall be payable in installments on each
Distribution Date as provided in the forms of Note set forth in Exhibit A.
Notwithstanding the foregoing, the entire unpaid principal amount of each class
of the Notes shall be due and payable, if not previously paid, on the Note Final
Maturity Date for such class of Notes and on the date on which an Event of
Default shall have occurred and be continuing if the Indenture Trustee or the
Noteholders of the Notes representing not less than a majority of the
Outstanding Amount of the Notes have declared the Notes to be immediately due
and payable in the manner provided in Section 5.2. All principal payments on the
Notes shall be made pro rata to the Noteholders entitled thereto. The Indenture
Trustee shall notify the Person in whose name a Note is registered at the close
of business on the Record Date preceding the Distribution Date on which the
Issuer expects that the final installment of principal of and interest on such
Note will be paid. Such notice shall be mailed or transmitted by facsimile prior
to such final Distribution Date and shall specify that such final installment
will be payable only upon presentation and surrender of such Note and shall
specify the place where such Note may be presented and surrendered for payment
of such Installment. Notices in connection with redemptions of Notes shall be
mailed to Noteholders as provided in Section 10.2.

      (c) If the Issuer defaults in a payment of interest on the Notes, the
Issuer shall pay the resulting Note Interest Shortfall on the following
Distribution Date as provided in the Administration Agreement.

            SECTION 2.8 Cancellation. All Notes surrendered for payment,
registration of transfer, exchange or redemption shall, if surrendered to any
Person other than the Indenture Trustee, be delivered to the Indenture Trustee
and shall be promptly cancelled by the Indenture Trustee. The Issuer may at any
time deliver to the Indenture Trustee for cancellation any Notes previously
authenticated and delivered hereunder


                                       9
<PAGE>

which the Issuer may have acquired in any manner whatsoever and all Notes so
delivered shall be promptly cancelled by the Indenture Trustee. No Notes shall
be authenticated in lieu of or in exchange for any Notes cancelled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Notes may be held or disposed of by the Indenture Trustee in accordance with its
standard retention or disposal policy as in effect at the time, unless the
Issuer shall direct by an Issuer Order that they be returned to it and so long
as such Issuer Order is timely and the Notes have not been previously disposed
of by the Indenture Trustee.

            SECTION 2.9 Release of Collateral. Subject to Section 11.1 and the
terms of the Basic Documents, the Indenture Trustee shall release property from
the lien of this Indenture only upon receipt of an Issuer Request accompanied by
an Officers' Certificate of the Issuer, an Opinion of Counsel and Independent
Certificates in accordance with TIA ss.ss. 314(c) and 314(d)(1) or an Opinion of
Counsel in lieu of such Independent Certificates to the effect that the TIA does
not require any such Independent Certificates.

            SECTION 2.10 Book-Entry Notes. The Notes, upon original issuance,
will be issued in the form of typewritten Notes representing the Book-Entry
Notes, to be delivered to The Depository Trust Company, the initial Clearing
Agency, by, or on behalf of, the Issuer. Such Notes shall initially be
registered on the Note Register in the name of Cede & Co., the nominee of the
initial Clearing Agency, and no Note Owner shall receive a Definitive Note (as
defined below) representing such Note Owner's interest in such Note, except as
provided in Section 2.12. Unless and until definitive, fully registered Notes
(the "Definitive Notes") have been issued to Note Owners pursuant to Section
2.12:

            (i) the provisions of this Section shall be in full force and
effect;

            (ii) the Note Registrar and the Indenture Trustee, and their
respective directors, officers, employees and agents, may deal with the Clearing
Agency for all purposes (including the payment of principal of and interest and
other amounts on the Notes) as the authorized representative of the Note Owners;

            (iii) to the extent that the provisions of this Section conflict
with any other provisions of this Indenture, the provisions of this Section
shall control;


                                       10
<PAGE>

            (iv) the rights of Note Owners shall be exercised only through the
Clearing Agency and shall be limited to those established by law and agreements
between such Note Owners and the Clearing Agency and/or the Clearing Agency
Participants pursuant to the Note Depository Agreement; and unless and until
Definitive Notes are issued pursuant to Section 2.12, the initial Clearing
Agency will make book-entry transfers among the Clearing Agency Participants and
receive and transmit payments of principal of and interest and other amounts on
the Notes to such Clearing Agency Participants; and

            (v) whenever this Indenture requires or permits actions to be taken
based upon instructions or directions of Noteholders of Notes evidencing a
specified percentage of the Outstanding Amount of the Notes, the Clearing Agency
shall be deemed to represent such percentage only to the extent that it has
received instructions to such effect from Note Owners and/or Clearing Agency
Participants owning or representing, respectively, such required percentage of
the beneficial interest in the Notes and has delivered such instructions to the
Indenture Trustee.

            SECTION 2.11 Notices to Clearing Agency. Whenever a notice or other
communication to the Noteholders is required under this Indenture, unless and
until Definitive Notes shall have been issued to Note Owners pursuant to Section
2.12, the Indenture Trustee shall give all such notices and communication
specified herein to be given to Noteholders to the Clearing Agency.

            SECTION 2.12 Definitive Notes. If (i) the Administrator advises the
Indenture Trustee in writing that the Clearing Agency is no longer willing or
able to discharge its responsibilities with respect to the Notes, and the
Administrator is unable to locate a successor, (ii) the Administrator at its
option advises the Indenture Trustee in writing that it elects to terminate the
book-entry system through the Clearing Agency or (iii) after the occurrence of
an Event of Default, a Servicer Default or an Administrator Default, Note Owners
representing beneficial interests aggregating at least a majority of the
Outstanding Amount of the Notes advise the Clearing Agency (which shall then
notify the Indenture Trustee) in writing that the continuation of a book-entry
system through the Clearing Agency is no longer in the best interests of the
Note Owners, then the Indenture Trustee shall cause the Clearing Agency to
notify all Note Owners, through the Clearing Agency, of the occurrence of any
such event and of the availability of Definitive Notes to Note Owners requesting
the same. Upon surrender to the Indenture Trustee of the typewritten Notes
representing the Book-


                                       11
<PAGE>

Entry Notes by the Clearing Agency, accompanied by registration instructions,
the Issuer shall execute and the Indenture Trustee shall authenticate the
Definitive Notes in accordance with the instructions of the Clearing Agency.
None of the Issuer, the Note Registrar or the Indenture Trustee shall be liable
for any delay in delivery of such instructions and may conclusively rely on, and
shall be protected in relying on, such instructions. Upon the issuance of
Definitive Notes, the Indenture Trustee shall recognize the holders of the
Definitive Notes as Noteholders. ARTICLE III

                                    Covenants

            SECTION 3.1 Payment to Noteholders. The Issuer shall duly and
punctually pay the principal and interest, if any, with respect to the Notes in
accordance with the terms of the Notes and this Indenture. Without limiting the
foregoing, subject to Section 8.2(c), the Issuer shall cause to be distributed
to Noteholders in accordance with the Administration Agreement that portion of
the amounts on deposit in the Trust Accounts on a Distribution Date (other than
any Eligible Investments deposited therein that will mature on the Business Day
preceding a subsequent Distribution Date) which the Noteholders are entitled to
receive pursuant to the Administration Agreement. Amounts properly withheld
under the Code by any Person from a payment to any Noteholder of interest and/or
principal shall be considered as having been paid by the Issuer to such
Noteholder for all purposes of this Indenture.

            SECTION 3.2 Maintenance of Office or Agency. The Issuer shall
maintain in the Borough of Manhattan, The City of New York, an office or agency
where Notes may be surrendered for registration of transfer or exchange, and
where notices and demands to or upon the Issuer in respect of the Notes and this
Indenture may be served. The Issuer hereby initially appoints the Indenture
Trustee to serve as its agent for the foregoing purposes. The Issuer shall give
prompt written notice to the Indenture Trustee of the location, and of any
change in the location, of any such office or agency. If at any time the Issuer
shall fail to maintain any such office or agency or shall fail to furnish the
Indenture Trustee with the address thereof, such surrenders, notices and demands
may be made or served at the Corporate Trust Office, and the Issuer hereby
appoints the Indenture Trustee as its agent to receive all such surrenders,
notices and demands.

Section 8.2(a) and (b), all payments of amounts due and payable with respect to
any Notes that are to be made from amounts distributed from the Collection
Account or any other Trust Account pursuant to Section 8.2(c) shall be made on
behalf of the Issuer by the Indenture Trustee or by another Paying Agent, and no
amounts so distributed from the Collection Account for payments of Notes shall
be paid over to the Issuer except as provided in this Section.

            On or before the Business Day next preceding each Distribution Date
and Redemption Date, the Issuer shall distribute or cause to be distributed to
the Indenture Trustee (or any other Paying Agent) an aggregate sum sufficient to
pay the amounts then becoming due under the Notes, such sum to be held in trust
for the benefit of the Persons entitled thereto and (unless the Paying Agent is
the Indenture Trustee) shall promptly notify the Indenture Trustee of its action
or failure so to act.

            The Issuer shall cause each Paying Agent other than the Indenture
Trustee to execute and deliver to the Indenture Trustee an instrument in which
such Paying Agent shall agree with the Indenture Trustee (and if the Indenture
Trustee acts as Paying Agent, it hereby so agrees), subject to the provisions of
this Section, that such Paying Agent will:

            (i) hold all sums held by it for the payment of amounts due with
respect to the Notes in trust for the benefit of the Persons entitled thereto
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and pay such sums to such Persons as herein provided;

            (ii) give the Indenture Trustee notice of any default by the Issuer
of which it has actual knowledge (or any other obligor upon the Notes) in the
making of any payment required to be made with respect to the Notes;

            (iii) at any time during the continuance of any such default, upon
the written request of the Indenture Trustee, forthwith pay to the Indenture
Trustee all sums so held in trust by such Paying Agent;

            (iv) immediately resign as a Paying Agent and forthwith pay to the
Indenture Trustee all sums held by it in trust for the payment of Notes if at
any time it


                                       13
<PAGE>

ceases to meet the standards required to be met by a Paying Agent at the time of
its appointment; and

            (v) comply with all requirements of the Code with respect to the
withholding from any payments made by it on any Notes of any applicable
withholding taxes imposed thereon and with respect to any applicable reporting
requirements in connection therewith.

            The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, by Issuer
Order direct any Paying Agent to pay to the Indenture Trustee all sums held in
trust by such Paying Agent, such sums to be held by the Indenture Trustee upon
the same trusts as those upon which the sums were held by such Paying Agent; and
upon such payment by any Paying Agent to the Indenture Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

            Subject to applicable laws with respect to escheat of funds, any
money held by the Indenture Trustee or any Paying Agent in trust for the payment
of any amount due with respect to any Note and remaining unclaimed for two years
after such amount has become due and payable shall be discharged from such trust
and be paid to the Issuer on Issuer Request or if the Issuer has been terminated
to Seller; and the Noteholder thereof shall thereafter, as an unsecured general
creditor, look only to the Issuer for payment thereof (but only to the extent of
the amounts so paid to the Issuer), and all liability of the Indenture Trustee
or such Paying Agent with respect to such trust money shall thereupon cease;
provided, however, that the Indenture Trustee or such Paying Agent, before being
required to make any such repayment, shall at the expense and direction of the
Issuer cause to be published once, in a newspaper published in the English
language, customarily published on each Business Day and of general circulation
in The City of New York, notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the
date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Issuer. The Indenture Trustee shall also adopt and employ,
at the expense of the Issuer, any other reasonable means of notification of such
repayment (including mailing notice of such repayment to Noteholders whose Notes
have been called but have not been surrendered for redemption or whose right to
or interest in moneys due and payable but not claimed is determinable from the
records of the Indenture Trustee or of any Paying Agent, at the last address of
record for each such Noteholder).

            SECTION 3.4 Existence. The Issuer shall keep in full effect its
existence, rights and franchises as a business trust under the laws of the State
of Delaware (unless it becomes, or any successor Issuer hereunder is or becomes,
organized under the laws of any other State or of the United States of America,
in which case the Issuer shall keep in full effect its existence, rights and
franchises under the laws of such other jurisdiction) and shall obtain and
preserve its qualification to do business in each jurisdiction in which such
qualification is or shall be necessary to protect the validity and
enforceability of this Indenture, the Notes, the Collateral and each other
instrument or agreement included in the Indenture Trust Estate.

            SECTION 3.5 Protection of Indenture Trust Estate. The Issuer will
from time to time execute and deliver all such supplements and amendments hereto
and all such financing statements, continuation statements, will take such other
action necessary or advisable to:

            (i) maintain or preserve the lien and security interest (and the
priority thereof) of this Indenture or carry out more effectively the purposes
hereof;

            (ii) perfect, publish notice of or protect the validity of any grant
made or to be made by this Indenture;

            (iii) enforce any of the Collateral; or

            (iv) preserve and defend title to the Indenture Trust Estate and the
rights of the Indenture Trustee and the Noteholders in such Indenture Trust
Estate against the claims of all persons and parties.

            The Issuer hereby designates the Indenture Trustee its agent and
attorney-in-fact to execute any financing statement, continuation statement or
other instrument required to be executed pursuant to this Section.

            SECTION 3.6 Opinions as to Indenture Trust Estate. (a) On the
Closing Date, the Issuer shall furnish to the Indenture Trustee an Opinion of
Counsel either stating that, in the opinion of such counsel, such action has
been taken with respect to the recording and filing of this Indenture as is
necessary to perfect and make effective the lien and security interest of this
Indenture and reciting the details of such


                                       15
<PAGE>

action, or stating that, in the opinion of such counsel, no such action is
necessary to make such lien and security interest effective.

      (b) On or before December 31 in each calendar year, beginning in 2000, the
Issuer shall furnish to the Indenture Trustee an Opinion of Counsel either
stating that, in the opinion of such counsel, such action has been taken with
respect to the recording, filing, re-recording and refiling of this Indenture
and any indentures supplemental hereto as is necessary to maintain the lien and
security interest created by this Indenture and relating the details of such
action or stating that in the opinion of such counsel no such action is
necessary to maintain such lien and security interest. Such Opinion of Counsel
shall also describe the recording, filing, recording and refiling of this
Indenture and any indentures supplemental hereto that will, in the opinion of
such counsel, be required to maintain the lien and security interest of this
Indenture until December 31 in the following calendar year.

            SECTION 3.7 Performance of Obligations; Servicing of Trust Student
Loans. (a) The Issuer will not take any action and will use its best efforts not
to permit any action to be taken by others that would release any Person from
any of such Person's material covenants or obligations under any instrument or
agreement included in the Indenture Trust Estate or that would result in the
amendment, hypothecation, subordination, termination or discharge of, or impair
the validity or effectiveness of, any such instrument or agreement, except as
expressly provided in this Indenture, any other Basic Document or such other
instrument or agreement.

      (b) The Issuer may contract with other Persons to assist it in performing
its duties under this Indenture, and any performance of such duties by a Person
identified to the Indenture Trustee in an Officers' Certificate of the Issuer
shall be deemed to be action taken by the Issuer; provided, however, the Issuer
shall not be liable for any acts of Persons with whom the Issuer has contracted
with reasonable care. Initially, the Issuer has contracted with the Servicer and
the Administrator to assist the Issuer in performing its duties under this
Indenture. The Issuer shall give written notice to the Indenture Trustee and
each Rating Agency of any such contract with any other Person.

      (c) The Issuer shall punctually perform and observe all of its obligations
and agreements contained in this Indenture, the other Basic Documents and the
instruments and agreements included in the Indenture Trust Estate, including
filing or causing to be filed all UCC financing statements and continuation
statements prepared


                                       16
<PAGE>

by the Issuer and required to be filed by the terms of this Indenture and the
Administration Agreement in accordance with and within the time periods provided
for herein and therein. Except as otherwise expressly provided therein, the
Issuer shall not waive, amend, modify, supplement or terminate any Basic
Document or any provision thereof without the consent of the Indenture Trustee
or the Noteholders of at least a majority of the Outstanding Amount of the
Notes. The Issuer shall give written notice to each Rating Agency of any such
waiver, amendment, modification, supplement or termination.

      (d) If a Responsible Officer of the Issuer shall have knowledge of the
occurrence of a Servicer Default or an Administrator Default under the Servicing
Agreement or the Administration Agreement, respectively, the Issuer shall
promptly notify the Indenture Trustee and the Rating Agencies thereof, and shall
specify in such notice the action, if any, the Issuer is taking with respect to
such default. If a Servicer Default shall arise from the failure of the Servicer
to perform any of its duties or obligations under the Servicing Agreement, or an
Administrator Default shall arise from the failure of the Administrator to
perform any of its duties or obligations under the Administration Agreement, as
the case may be, with respect to the Trust Student Loans, the Issuer shall take
all reasonable steps available to it to enforce its rights under the Basic
Documents in respect of such failure.

      (e) As promptly as possible after the giving of notice of termination to
the Servicer of the Servicer's rights and powers, pursuant to Section 5.1 of the
Servicing Agreement, or to the Administrator of the Administrator's rights and
powers, pursuant to Section 5.1 of the Administration Agreement, the Issuer
shall appoint a successor servicer (the "Successor Servicer") or a successor
administrator (the "Successor Administrator"), respectively, and such Successor
Servicer or Successor Administrator, as the case may be, shall accept its
appointment by a written assumption in a form acceptable to the Indenture
Trustee. In the event that a Successor Servicer or Successor Administrator has
not been appointed and accepted its appointment at the time when the Servicer or
Administrator, as the case may be, ceases to act as Servicer or Administrator,
respectively, the Indenture Trustee without further action shall automatically
be appointed the Successor Servicer or Successor Administrator, as the case may
be. The Indenture Trustee may resign as the Servicer or the Administrator by
giving written notice of resignation to the Issuer and in such event will be
released from such duties and obligations, such release not to be effective
until the date a new servicer or a new administrator enters into an agreement
with the Issuer as provided below;


                                       17
<PAGE>

provided, however, that nothing herein shall require or permit the Indenture
Trustee to act as Servicer, or otherwise service the Trust Student Loans, in
violation of the Higher Education Act. Upon delivery of any such notice to the
Issuer, the Issuer shall obtain a new servicer as the Successor Servicer under
the Servicing Agreement or a new administrator as the Successor Administrator
under the Administration Agreement, as the case may be. Any Successor Servicer
or Successor Administrator, other than the Indenture Trustee, shall (i) be an
established institution (A) that satisfies any requirements of the Higher
Education Act applicable to servicers and (B) whose regular business includes
the servicing or administration of student loans and (ii) enter into a servicing
agreement or an administration agreement, respectively, with the Issuer having
substantially the same provisions as the provisions of the Servicing Agreement
and the Administration Agreement, as applicable. If within 30 days after the
delivery of the notice referred to above, the Issuer shall not have obtained
such a new servicer or new administrator, as the case may be, the Indenture
Trustee may appoint, or may petition a court of competent jurisdiction to
appoint, a Successor Servicer or Successor Administrator; provided, however,
that such right to appoint or to petition for the appointment of any such
successor shall in no event relieve the Indenture Trustee from any obligations
otherwise imposed on it under the Basic Documents until such successor has in
fact assumed such appointment. In connection with any such appointment, the
Indenture Trustee may make such arrangements for the compensation of such
successor as it and such successor shall agree, subject to the limitations set
forth below and in the Servicing Agreement or Administration Agreement, as
applicable, and in accordance with Section 5.2 of the Servicing Agreement and
Section 5.2 of the Administration Agreement, the Issuer shall enter into an
agreement with such successor for the servicing or administration of the Trust
Student Loans (such agreement to be in form and substance satisfactory to the
Indenture Trustee). If the Indenture Trustee shall succeed as provided herein to
the Servicer's duties as Servicer with respect to the Trust Student Loans, or
the Administrator's duties with respect to the Issuer and the Trust Student
Loans, as the case may be, it shall do so in its individual capacity and not in
its capacity as Indenture Trustee and, accordingly, the provisions of Article VI
hereof shall be inapplicable to the Indenture Trustee in its duties as the
successor to the Servicer or the Administrator, as the case may be, and the
servicing or administration of the Trust Student Loans. In case the Indenture
Trustee shall become successor to the Servicer or the Administrator, the
Indenture Trustee shall be entitled to appoint as Servicer or as Administrator,
as the case may be, any one of its Affiliates, provided that such appointment
shall not affect or alter in any way the liability of the Indenture Trustee as
Successor Servicer or Successor Administrator, respectively, in accordance with
the terms hereof.


                                       18
<PAGE>

      (f) Upon any termination of the Servicer's rights and powers pursuant to
the Servicing Agreement, or any termination of the Administrator's rights and
powers pursuant to the Administration Agreement, as the case may be, the Issuer
shall promptly notify the Indenture Trustee and each Rating Agency. As soon as a
Successor Servicer or a Successor Administrator is appointed, the Issuer shall
notify the Indenture Trustee and each Rating Agency of such appointment,
specifying in such notice the name and address of such Successor Servicer or
such Successor Administrator.

      (g) Without derogating from the absolute nature of the assignment granted
to the Indenture Trustee under this Indenture or the rights of the Indenture
Trustee hereunder, the Issuer agrees that it will not, without the prior written
consent of the Indenture Trustee or the Noteholders of at least a majority in
Outstanding Amount of the Notes, amend, modify, waive, supplement, terminate or
surrender, or agree to any amendment, modification, supplement, termination,
waiver or surrender of, the terms of any Collateral or the Basic Documents,
except to the extent otherwise provided in the Basic Documents, or waive timely
performance or observance by the Servicer, the Administrator, the Seller, the
Student Loan Marketing Association, the Issuer or the Eligible Lender Trustee
under the Basic Documents; provided, however, that no such amendment shall (i)
increase or reduce in any manner the amount of, or accelerate or delay the
timing of, distributions that are required to be made for the benefit of the
Noteholders, or (ii) reduce the aforesaid percentage of the Notes which are
required to consent to any such amendment, without the consent of the
Noteholders of all the Outstanding Notes. If any such amendment, modification,
supplement or waiver shall be so consented to by the Indenture Trustee or such
Noteholders, the Issuer shall give written notice thereof to each Rating Agency
and agrees, promptly following a request by the Indenture Trustee to do so, to
execute and deliver, in its own name and at its own expense, such agreements,
instruments, consents and other documents as the Indenture Trustee may deem
necessary or appropriate in the circumstances.

            SECTION 3.8 Negative Covenants. So long as any Notes are
Outstanding, the Issuer shall not:

            (i) except as expressly permitted by this Indenture or any other
Basic Document, sell, transfer, exchange or otherwise dispose of any of the
properties or assets of the Issuer, including those included in the Indenture
Trust Estate, unless directed to do so by the Indenture Trustee;


                                       19
<PAGE>

            (ii) claim any credit on, or make any deduction from the principal
or interest payable in respect of, the Notes (other than amounts properly
withheld from such payments under the Code or applicable state law) or assert
any claim against any present or former Noteholder by reason of the payment of
the taxes levied or assessed upon any part of the Indenture Trust Estate;

            (iii) (A) permit the validity or effectiveness of this Indenture to
be impaired, or permit the lien of this Indenture to be amended, hypothecated,
subordinated, terminated or discharged, or permit any Person to be released from
any covenants or obligations with respect to the Notes under this Indenture
except as may be expressly permitted hereby, (B) permit any lien, charge,
excise, claim, security interest, mortgage or other encumbrance (other than the
lien of this Indenture) to be created on or extend to or otherwise arise upon or
burden the Indenture Trust Estate or any part thereof or any interest therein or
the proceeds thereof (other than tax liens and other liens that arise by
operation of law, and other than as expressly permitted by the Basic Documents)
or (C) permit the lien of this Indenture not to constitute a valid first
priority (other than with respect to any such tax or other lien) security
interest in the Indenture Trust Estate; or

            (iv) enter into any amendment to a Swap Agreement requested by the
applicable Swap Counterparty to cure any ambiguity in, or to correct or
supplement any provision of that Swap Agreement, except where the Issuer has
received the consent of the Indenture Trustee so long as the Issuer has
determined, and the Indenture Trustee has agreed in writing at the written
direction of the Issuer, that the amendment will not materially adversely affect
the interests of the Noteholders and provided that the Indenture Trustee has
provided reasonable notice to the Rating Agencies of such amendment.

            SECTION 3.9 Annual Statement as to Compliance. The Issuer will
deliver to the Indenture Trustee and each Rating Agency, within 120 days after
the end of each fiscal year of the Issuer (commencing with the fiscal year
2000), an Officers' Certificate of the Issuer stating that:

            (i) a review of the activities of the Issuer during such year and of
performance under this Indenture has been made under such Authorized Officers'
supervision; and


                                       20
<PAGE>

            (ii) to the best of such Authorized Officers' knowledge, based on
such review, the Issuer has complied with all conditions and covenants under
this Indenture throughout such year, or, if there has been a default in the
compliance of any such condition or covenant, specifying each such default known
to such Authorized Officers and the nature and status thereof.

            SECTION 3.10 Issuer May Consolidate, etc., Only on Certain Terms.

      (a) The Issuer shall not consolidate or merge with or into any other
Person, unless:

            (i) the Person (if other than the Issuer) formed by or surviving
such consolidation or merger shall be a Person organized and existing under the
laws of the United States of America or any State and shall expressly assume, by
an indenture supplemental hereto, executed and delivered to the Indenture
Trustee, in form satisfactory to the Indenture Trustee, the due and punctual

performance or observance of every agreement and covenant of this Indenture on
the part of the Issuer to be performed or observed, all as provided herein;

            (ii) immediately after giving effect to such transaction, no Default

            (iii) the Rating Agency Condition shall have been satisfied with

            (iv) the Issuer shall have received an Opinion of Counsel (and shall

transaction will not have any material adverse Federal or Delaware state tax
consequence to the Issuer, any Noteholder or any Certificateholder;

            (v) any action as is necessary to maintain the lien and security
interest created by this Indenture shall have been taken; and

            (vi) the Issuer shall have delivered to the Indenture Trustee an
Officers' Certificate of the Issuer and an Opinion of Counsel each stating that
such


                                       21

consolidation or merger and such supplemental indenture comply with this Article
III and that all conditions precedent herein provided for relating to such

      (b) The Issuer shall not convey or transfer all or substantially all its

any Person, unless:

            (i) the Person that acquires by conveyance or transfer the
properties and assets of the Issuer the conveyance or transfer of which is
hereby restricted shall (A) be a United States citizen or a Person organized and
existing under the laws of the United States of America or any State, (B)

indenture that such Person (or if a group of Persons, then one specified Person)
shall make all filings with the Commission (and any other appropriate Person)
required by the Exchange Act in connection with the Notes;

            (ii) immediately after giving effect to such transaction, no Default
shall have occurred and be continuing;

            (iii) the Rating Agency Condition shall have been satisfied with
respect to such transaction;

            (iv) the Issuer shall have received an Opinion of Counsel (and shall

Exchange Act).

            SECTION 3.11 Successor or Transferee. (a) Upon any consolidation or
merger of the Issuer in accordance with Section 3.10(a), the Person formed by or
surviving such consolidation or merger (if other than the Issuer) shall succeed

                        (i) have become due and payable,

                        (ii) will become due and payable at their respective
Note Final Maturity Date, within one year, or

                        (iii) are to be called for redemption within one year
under arrangements satisfactory to the Indenture Trustee for the giving of
notice of redemption by the Indenture Trustee in the name, and at the expense,
of the Issuer, and the Issuer, in the case of (i), (ii) or (iii) above, has
irrevocably deposited or caused to be irrevocably deposited with the Indenture
Trustee cash or direct obligations of or obligations guaranteed by the United
States of America (which will mature prior to the date such amounts are
payable), in trust for such purpose, in an amount sufficient to pay and
discharge the entire indebtedness on such Notes not theretofore delivered to the
Indenture Trustee for cancellation when due to the Note Final Maturity Date;

            (b) the Issuer has paid or caused to be paid all other sums payable
hereunder by the Issuer; and

            (c) the Issuer has delivered to the Indenture Trustee an Officers'
Certificate of the Issuer, an Opinion of Counsel and (if required by the TIA or
the Indenture Trustee) an Independent Certificate from a firm of certified
public accountants, each meeting the applicable requirements of Section 11.1(a)
and, subject to Section 11.2, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have
been complied with.

            SECTION 4.2 Application of Trust Money. All moneys deposited with
the Indenture Trustee pursuant to Section 4.1 hereof shall be held in trust and
applied by it, in accordance with the provisions of the Notes and this
Indenture, to the payment, either directly or through any Paying Agent, as the
Indenture Trustee may determine, to the Noteholders of the particular Notes for
the payment or redemption of which such moneys have been deposited with the
Indenture Trustee, of all sums due and to become due thereon for principal and
interest; but such moneys need not be segregated from other funds except to the
extent required herein or in the Administration Agreement or required by law.

            SECTION 4.3 Repayment of Moneys Held by Paying Agent. In connection
with the satisfaction and discharge of this Indenture with respect to the Notes,
all moneys then held by any Paying Agent other than the Indenture Trustee under
the provisions of this Indenture with respect to such Notes shall, upon demand
of the Issuer, be paid to the Indenture Trustee to be held and applied according
to Section 3.3 and thereupon such Paying Agent shall be released from all
further liability with respect to such moneys.

            SECTION 4.4 Auction of Trust Student Loans. Any Trust Student Loans
remaining in the Trust as of the end of the Collection Period immediately
preceding the earliest Distribution Date on which the Pool Balance is equal to
10% or less of the initial Pool Balance three business days prior to such
Distribution Date (the "Trust Auction Date") shall be offered for sale by the
Indenture Trustee unless the Seller has exercised its option to purchase the
Trust Estate as described in Section 6.1A of the Administration Agreement with
respect to such Distribution Date. The Seller will be deemed to have waived such
option if it fails to notify the Eligible Lender Trustee and the Indenture
Trustee of its exercise thereof in writing prior to the Indenture Trustee's
acceptance of a bid to purchase such Trust Student Loans; provided, however,
that there shall be no such offer for sale if the Indenture Trustee fails to
provide notice to the Seller in accordance with this Section 4.4. The Indenture
Trustee shall provide written notice to the Seller of any such offer for sale at
least 5 business days in advance of the Trust Auction Date. The Indenture
Trustee shall permit the Seller or any of its Affiliates to offer bids only if
the Pool Balance as of the applicable Trust Auction Date is equal to 10% or less
of the Initial Pool Balance. If at least two bids are received, the Indenture
Trustee shall solicit and resolicit new bids from all participating bidders
until only one bid remains or the remaining bidders decline to resubmit bids.
The Indenture Trustee shall accept the highest of such remaining bids if it is
equal to or in excess of both the Minimum Purchase Amount and the fair market
value of such Trust Student Loans as of the end of the Collection Period
immediately preceding the Trust Auction Date. If at least two bids are not
received or the highest bid after the resolicitation process is completed is not
equal to or in excess of the higher of the Minimum Purchase Amount and the fair
market value of the Trust Student Loans, the Indenture Trustee shall not
consummate such sale. The Indenture Trustee may consult, and, at the direction
of the Seller, shall consult, with a financial advisor, including an underwriter
of the Notes or the Administrator, to determine if the fair market value of the
Trust Student Loans has been offered. The proceeds of any such sale will be
applied in the order of priority set forth in Section 5.4 (b). If the sale is
not consummated in


                                       27
<PAGE>

accordance with the foregoing, the Indenture Trustee may, but shall not be under
any obligation to, solicit bids for sale of the Trust Student Loans with respect
to future Distribution Dates upon terms similar to those described above,
including the Seller's waiver of its option to purchase the Trust Estate in
accordance with Section 6.1A of the Administration Agreement with respect to
each such future Distribution Date.

                                    ARTICLE V

                                    Remedies

            SECTION 5.1 Events of Default. "Event of Default," wherever used
herein, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

            (i) default in the payment of any interest on any Note when the same
becomes due and payable, and such default shall continue for a period of five
days; or

            (ii) default in the payment of the principal of any Note when the
same becomes due and payable on the related Note Final Maturity Date; or

            (iii) default in the observance or performance of any covenant or
agreement of the Issuer made in this Indenture (other than a covenant or
agreement, a default in the observance or performance of which is elsewhere in
this Section specifically dealt with),or any representation or warranty of the
Issuer made in this Indenture or in any certificate or other writing having been
incorrect in any material respect as of the time when made, such default or
breach having a material adverse effect on the holders of the Notes, and such
default or breach shall continue or not be cured, or the circumstance or
condition in respect of which such misrepresentation or warranty was incorrect
shall not have been eliminated or otherwise cured, for a period of 30 days after
there shall have been given, by registered or certified mail, to the Issuer by
the Indenture Trustee or to the Issuer and the Indenture Trustee by the
Noteholders of at least 25% of the Outstanding Amount of the Notes, a written
notice specifying such default or incorrect representation or warranty and
requiring it to be remedied and stating that such notice is a notice of Default
hereunder; or


                                       28
<PAGE>

            (iv) the filing of a decree or order for relief by a court having
jurisdiction in the premises in respect of the Issuer or any substantial part of
the Indenture Trust Estate in an involuntary case under any applicable Federal
or state bankruptcy, insolvency or other similar law now or hereafter in effect,
or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator
or similar official of the Issuer or for any substantial part of the Indenture
Trust Estate, or ordering the winding-up or liquidation of the Issuer's affairs,
and such decree or order shall remain unstayed and in effect for a period of 60
consecutive days; or

            (v) the commencement by the Issuer of a voluntary case under any
applicable Federal or state bankruptcy, insolvency or other similar law now or
hereafter in effect, or the consent by the Issuer to the entry of an order for
relief in an involuntary case under any such law, or the consent by the Issuer
to the appointment or taking possession by a receiver, liquidator, assignee,
custodian, trustee, sequestrator or similar official of the Issuer or for any
substantial part of the Indenture Trust Estate, or the making by the Issuer of
any general assignment for the benefit of creditors, or the failure by the
Issuer generally to pay its debts as such debts become due, or the taking of
action by the Issuer in furtherance of any of the foregoing.

            SECTION 5.2 Acceleration of Maturity; Rescission and Annulment. If
an Event of Default should occur and be continuing, then and in every such case
the Indenture Trustee or the Noteholders of Notes representing not less than a
majority of the Outstanding Amount of the Notes may declare all the Notes to be
immediately due and payable, by a notice in writing to the Issuer (and to the
Indenture Trustee if given by Noteholders), and upon any such declaration the
unpaid principal amount of such Notes, together with accrued and unpaid interest
thereon through the date of acceleration, shall become immediately due and
payable.

            At any time after such declaration of acceleration of maturity has
been made and before a judgment or decree for payment of the money due has been
obtained by the Indenture Trustee as hereinafter in this Article V provided, the
Noteholders of Notes representing a majority of the Outstanding Amount of the
Notes, by written notice to the Issuer and the Indenture Trustee, may rescind
and annul such declaration and its consequences if:

            (i) the Issuer has paid or deposited with the Indenture Trustee a
sum sufficient to pay:


                                       29
<PAGE>

      (a) all payments of principal of and interest on all Notes and all other
amounts that would then be due hereunder or upon such Notes if the Event of
Default giving rise to such acceleration had not occurred; and

      (b) all sums paid or advanced by the Indenture Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Indenture
Trustee and its agents and counsel; and

            (ii) all Events of Default, other than the nonpayment of the
principal of the Notes that has become due solely by such acceleration, have
been cured or waived as provided in Section 5.12.

            No such rescission shall affect any subsequent default or impair any
right consequent thereto.

            SECTION 5.3 Collection of Indebtedness and Suits for Enforcement by
Indenture Trustee. The Issuer covenants that if (i) default is made in the
payment of any interest on any Note when the same becomes due and payable, and
such default continues for a period of five days, or (ii) default is made in the
payment of the principal of any Note when the same becomes due and payable at
the related Note Final Maturity Date, the Issuer shall, upon demand of the
Indenture Trustee, pay to it, for the benefit of the Noteholders, the whole
amount then due and payable on such Notes for principal and interest, with
interest upon the overdue principal, and, to the extent payment at such rate of
interest shall be legally enforceable, upon overdue installments of interest, at
the rate specified in Section 2.7 and in addition thereto such further amount as
shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Indenture
Trustee and its agents and counsel.

      (a) In case the Issuer shall fail forthwith to pay such amounts upon such
demand, the Indenture Trustee, in its own name and as trustee of an express
trust, may institute a Proceeding for the collection of the sums so due and
unpaid, and may prosecute such Proceeding to judgment or final decree, and may
enforce the same against the Issuer or other obligor upon such Notes and collect
in the manner provided by law out of the property of the Issuer or other obligor
upon such Notes, wherever situated, the moneys adjudged or decreed to be
payable.


                                       30
<PAGE>

      (b) If an Event of Default occurs and is continuing, the Indenture Trustee
may, as more particularly provided in Section 5.4, in its discretion, proceed to
protect and enforce its rights and the rights of the Noteholders, by such
appropriate Proceedings as the Indenture Trustee shall deem most effective to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy or legal or equitable
right vested in the Indenture Trustee by this Indenture or by law.

      (c) In case there shall be pending, relative to the Issuer or any other
obligor upon the Notes or any Person having or claiming an ownership interest in
the Indenture Trust Estate, Proceedings under Title 11 of the United States Code
or any other applicable Federal or state bankruptcy, insolvency or other similar
law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Issuer or its property or such other obligor or Person,
or in case of any other, comparable judicial Proceedings relative to the Issuer
or other obligor upon the Notes, or to the creditors or property of the Issuer
or such other obligor, the Indenture Trustee, irrespective of whether the
principal of any Notes shall then be due and payable, as therein expressed or by
declaration or otherwise and irrespective of whether the Indenture Trustee shall
have made any demand pursuant to the provisions of this Section, shall be
entitled and empowered, by intervention in such proceedings or otherwise:

            (i) to file and prove a claim or claims for the whole amount of
principal and interest owing and unpaid in respect of the Notes and to file such
other papers or documents as may be necessary or advisable in order to have the
claims of the Indenture Trustee (including any claim for reasonable compensation
to the Indenture Trustee and each predecessor Indenture Trustee, and their
respective agents, attorneys and counsel, and for reimbursement of all expenses
and liabilities incurred, and all advances made, by the Indenture Trustee and
each predecessor Indenture Trustee, except as a result of negligence or bad
faith) and of the Noteholders allowed in such Proceedings;

            (ii) unless prohibited by applicable law and regulations, to vote on
behalf of the Noteholders in any election of a trustee, a standby trustee or
Person performing similar functions in any such Proceedings;


                                       31
<PAGE>

            (iii) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute all amounts received with
respect to the claims of the Noteholders and of the Indenture Trustee on their
behalf; and

            (iv) to file such proofs of claim and other papers or documents as
may be necessary or advisable in order to have the claims of the Indenture
Trustee or the Noteholders allowed in any judicial proceedings relative to the
Issuer, its creditors and its property;

            and any trustee, receiver, liquidator, custodian or other similar
official in any such Proceeding is hereby authorized by each of such Noteholders
to make payments to the Indenture Trustee, and, in the event that the Indenture
Trustee shall consent to the making of payments directly to such Noteholders, to
pay to the Indenture Trustee such amounts as shall be sufficient to cover
reasonable compensation to the Indenture Trustee, each predecessor Indenture
Trustee and their respective agents, attorneys and counsel, and all other
expenses and liabilities incurred, and all advances made, by the Indenture
Trustee and each predecessor Indenture Trustee except as a result of negligence
or bad faith.

      (d) Nothing herein contained shall be deemed to authorize the Indenture
Trustee to authorize or consent to or vote for or accept or adopt on behalf of
any Noteholder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Noteholder thereof or to
authorize the Indenture Trustee to vote in respect of the claim of any
Noteholder in any such proceeding except, as aforesaid, to vote for the election
of a trustee in bankruptcy or similar Person.

      (e) All rights of action and of asserting claims under this Indenture, or
under any of the Notes, may be enforced by the Indenture Trustee without the
possession of any of the Notes or the production thereof in any trial or other
Proceedings relative thereto, and any such action or Proceedings instituted by
the Indenture Trustee shall be brought in its own name as trustee of an express
trust, and any recovery of judgment, subject to the payment of the expenses,
disbursements and compensation of the Indenture Trustee, each predecessor
Indenture Trustee and their respective agents and attorneys, shall be for the
ratable benefit of the Noteholders.


                                       32
<PAGE>

      (f) In any Proceedings brought by the Indenture Trustee (and also any
Proceedings involving the interpretation of any provision of this Indenture to
which the Indenture Trustee shall be a party), the Indenture Trustee shall be
held to represent all the Noteholders, and it shall not be necessary to make any
Noteholder a party to any such Proceedings.

            SECTION 5.4 Remedies; Priorities. If an Event of Default shall have
occurred and be continuing, the Indenture Trustee may do one or more of the
following (subject to Section 5.5):

      (a) (i) institute Proceedings in its own name and as trustee of an express
trust for the collection of all amounts then payable on the Notes or under this
Indenture with respect thereto, whether by declaration or otherwise, enforce any
judgment obtained, and collect from the Issuer and any other obligor upon such
Notes moneys adjudged due;

            (ii) institute Proceedings from time to time for the complete or
partial foreclosure of this Indenture, with respect to the Indenture Trust
Estate;

            (iii) exercise any remedies of a secured party under the UCC with
respect to the Trust Estate and take any other appropriate action to protect and
enforce the rights and remedies of the Indenture Trustee and the Noteholders;

            (iv) sell the Indenture Trust Estate or any portion thereof or
rights or interest therein, at one or more public or private sales called and
conducted in any manner permitted by law; and/or

            (v) elect to have the Eligible Lender Trustee maintain ownership of
the Trust Student Loans and continue to apply collections with respect to the
Trust Student Loans as if there had been no declaration of acceleration.

provided, however, that the Indenture Trustee may not sell or otherwise
liquidate the Indenture Trust Estate following an Event of Default, other than
an Event of Default described in Section 5.1(i) or (ii), unless (A) the
Noteholders of 100% of the Outstanding Amount of the Notes consent thereto, (B)
the proceeds of such sale or liquidation distributable to the Noteholders are
sufficient to discharge in full all amounts then due and unpaid upon such Notes
for principal and interest or (C) the


                                       33
<PAGE>

Indenture Trustee determines that the Indenture Trust Estate will not continue
to provide sufficient funds for the payment of principal of and interest on the
Notes as they would have become due if the Notes had not been declared due and
payable, and the Indenture Trustee obtains the consent of Noteholders of 66-2/3%
of the Outstanding Amount of the Notes; provided, further, that the Indenture
Trustee may not sell or otherwise liquidate the Indenture Trust Estate following
an Event of Default, other than an Event of Default described in Section 5.1(i)
or (ii), unless (D) the proceeds of such sale or liquidation distributable to
the Certificateholders plus the proceeds of the sale or liquidation of the Trust
Estate distributable to the Certificateholders are sufficient to pay to the
Certificateholders the outstanding Certificate Principal Balance plus accrued
and unpaid interest thereon or (E) after receipt of notice from the Eligible
Lender Trustee that the proceeds of such sale or liquidation distributable to
the Certificateholders plus the proceeds of the sale or liquidation of the Trust
Estate distributable to the Certificateholders would not be sufficient to pay to
the Certificateholders the outstanding Certificate Principal Balance plus
accrued and unpaid interest thereon, the Certificateholders of at least a
majority of the Certificate Principal Balance consent thereto. In determining
such sufficiency or insufficiency with respect to clauses (B), (C), (D) and (E),
the Indenture Trustee may, but need not, obtain and rely upon an opinion of an
Independent investment banking or accounting firm of national reputation as to
the feasibility of such proposed action and as to the sufficiency of the
Indenture Trust Estate and/or Trust Estate, as applicable, for such purpose.

      (b) If the Indenture Trustee collects any money or property pursuant to
this Article V, it shall pay out the money or property in the following order:

            FIRST: to the Indenture Trustee for amounts due under Section 6.7;

            SECOND: to the Servicer for due and unpaid Primary Servicing Fees;

            THIRD: to the Swap Counterparties, pro rata, for any due and unpaid
Swap Fees;

            FOURTH: to Noteholders for amounts due and unpaid on the Notes for
interest, ratably, without preference or priority of any kind, according to the
amounts due and payable on the Notes for such interest;


                                       34
<PAGE>

            FIFTH: to Noteholders for amounts due and unpaid on the Notes for
principal, ratably, without preference or priority of any kind, according to the
amounts due and payable on the Notes for principal;

            SIXTH: to the Issuer for distribution to the Certificateholders in
respect of any unpaid Certificate Principal Balance and unpaid interest on the
Certificates;

            SEVENTH: to the Swap Counterparties for any due and unpaid Floating
Rate Payments (as defined in the Swap Agreements);

            EIGHTH: to the Servicer, for any unpaid Carryover Servicing Fees;

            and

            NINTH: to the Issuer, for distribution in accordance with the terms
of the Administration Agreement and the Trust Agreement.

            The Indenture Trustee may fix a record date and payment date for any
payment to Noteholders pursuant to this Section. At least 15 days before such
record date, the Indenture Trustee shall mail to each Noteholder and the Issuer
a notice that states the record date, the payment date and the amount to be
paid.

            SECTION 5.5 Optional Preservation of the Trust Student Loans. If the
Notes have been declared to be due and payable under Section 5.2 following an
Event of Default and such declaration and its consequences have not been
rescinded and annulled, the Indenture Trustee may, but need not, elect to
maintain possession of the Indenture Trust Estate. It is the desire of the
parties hereto and the Noteholders that there be at all times sufficient funds
for the payment of principal of and interest on the Notes, and the Indenture
Trustee shall take such desire into account when determining whether or not to
maintain possession of the Indenture Trust Estate. In determining whether to
maintain possession of the Indenture Trust Estate, the Indenture Trustee may,
but need not, obtain and rely upon an opinion of an Independent investment
banking or accounting firm of national reputation as to the feasibility of such
proposed action and as to the sufficiency of the Indenture Trust Estate for such
purpose.


                                       35

            SECTION 5.6 Limitation of Suits. No Noteholder shall have any right
to institute any Proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless:

            (i) such Noteholder has previously given written notice to the
Indenture Trustee of a continuing Event of Default;

            (ii) the Noteholders of not less than 25% of the Outstanding Amount
of the Notes have made written request to the Indenture Trustee to institute
such Proceeding in respect of such Event of Default in its own name as Indenture
Trustee hereunder;

            (iii) such Noteholder or Noteholders have offered to the Indenture
Trustee reasonable indemnity against the costs, expenses and liabilities to be
incurred in complying with such request;

            (iv) the Indenture Trustee for 60 days after its receipt of such
notice, request and offer of indemnity has failed to institute such Proceeding;
and

            (v) no direction inconsistent with such written request has been
given to the Indenture Trustee during such 60-day period by the Noteholders of a
majority of the Outstanding Amount of the Notes;

            it being understood and intended that no one or more Noteholders
shall have any right in any manner whatever by virtue of, or by availing of, any
provision of this indenture to affect, disturb or prejudice the rights of any
other Noteholders or to obtain or to seek to obtain priority or preference over
any other Noteholders or to enforce any right under this Indenture, except in
the manner herein provided.

            In the event the Indenture Trustee shall receive conflicting or
inconsistent requests and indemnity from two or more groups of Noteholders, each
representing less than a majority of the Outstanding Amount of the Notes, the
Indenture Trustee in its sole discretion may determine what action, if any,
shall be taken, notwithstanding any other provisions of this Indenture.

            SECTION 5.7 Unconditional Rights of Noteholders To Receive Principal
and Interest. Notwithstanding any other provisions in this Indenture, any


                                       36
<PAGE>

Noteholder shall have the right, which is absolute and unconditional, to receive
payment of the principal of and interest on such Note on or after the respective
due dates thereof expressed in such Note or in this Indenture (or, in the case
of redemption, on or after the Redemption Date) and to institute suit for the
enforcement of any such payment, and such right shall not be impaired without
the consent of such Noteholder.

            SECTION 5.8 Restoration of Rights and Remedies. If the Indenture
Trustee or any Noteholder has instituted any Proceeding to enforce any right or
remedy under this Indenture and such Proceeding has been discontinued or
abandoned for any reason or has been determined adversely to the Indenture
Trustee or to such Noteholder, then and in every such case the Issuer, the
Indenture Trustee and the Noteholders shall, subject to any determination in
such Proceeding, be restored severally and respectively to their former
positions hereunder, and thereafter all rights and remedies of the Indenture
Trustee and the Noteholders shall continue as though no such Proceeding had been
instituted.

            SECTION 5.9 Rights and Remedies Cumulative. No right or remedy
herein conferred upon or reserved to the Indenture Trustee or to the Noteholders
is intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

            SECTION 5.10 Delay or Omission Not a Waiver. No delay or omission of
the Indenture Trustee or any Noteholder to exercise any right or remedy accruing
upon any Default shall impair any such right or remedy or constitute a waiver of
any such Default or an acquiescence therein. Every right and remedy given by
this Article V or by law to the Indenture Trustee or to the Noteholders may be
exercised from time to time, and as often as may be deemed expedient, by the
Indenture Trustee or by the Noteholders, as the case may be.

            SECTION 5.11 Control by Noteholders. The Noteholders of a majority
of the Outstanding Amount of the Notes shall have the right to direct the time,
method and place of conducting any Proceeding for any remedy available to the
Indenture


                                       37
<PAGE>

Trustee with respect to the Notes or exercising any trust or power conferred on
the Indenture Trustee; provided that

            (i) such direction shall not be in conflict with any rule of law or
with this Indenture;

            (ii) subject to the express terms of Section 5.4, any direction to
the Indenture Trustee to sell or liquidate the Indenture Trust Estate shall be
by the Noteholders of not less than 100% of the Outstanding Amount of the Notes;

            (iii) if the conditions set forth in Section 5.5 have been satisfied
and the Indenture Trustee elects to retain the Indenture Trust Estate pursuant
to such Section, then any direction to the Indenture Trustee by Noteholders of
less than 100% of the Outstanding Amount of the Notes to sell or liquidate the
Indenture Trust Estate shall be of no force and effect; and

            (iv) the Indenture Trustee may take any other action deemed proper
by the Indenture Trustee that is not inconsistent with such direction;

provided, however, that, subject to Section 6.1, the Indenture Trustee need not
take any action that it determines might involve it in liability or might
materially adversely affect the rights of any Noteholders not consenting to such
action.

            SECTION 5.12 Waiver of Past Defaults. Prior to the time a judgment
or decree for payment of money due has been obtained as described in Section
5.2, the Noteholders of not less than a majority of the Outstanding Amount of
the Notes may waive any past Default and its consequences except a Default (a)
in payment when due of principal of or interest on any of the Notes or (b) in
respect of a covenant or provision hereof which cannot be modified or amended
without the consent of each Noteholder. In the case of any such waiver, the
Issuer, the Indenture Trustee and the Noteholders shall be restored to their
former positions and rights hereunder, respectively; but no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereto.

            Upon any such waiver, such Default shall cease to exist and be
deemed to have been cured and not to have occurred for every purpose of this
Indenture; but no


                                       38
<PAGE>

such waiver shall extend to any subsequent or other Default or impair any right
consequent thereto.

            SECTION 5.13 Undertaking for Costs. All parties to this Indenture
agree, and each Noteholder by such Noteholder's acceptance of any Note shall be
deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture, or in any suit
against the Indenture Trustee for any action taken, suffered or omitted by it as
Indenture Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to (a) any suit instituted by the
Indenture Trustee, (b) any suit instituted by any Noteholder, or group of
Noteholders, in each case holding in the aggregate more than 10% of the
Outstanding Amount of the Notes or (c) any suit Instituted by any Noteholder for
the enforcement of the payment of principal of or interest on any Note on or
after the respective due dates expressed in such Note and in this Indenture (or,
in the case of redemption, on or after the Redemption Date).

            SECTION 5.14 Waiver of Stay or Extension Laws. The Issuer covenants
(to the extent that it may lawfully do so) that it will not at any time insist
upon, or plead or in any manner whatsoever, claim or take the benefit or
advantage of, any stay or extension law wherever enacted, now or at any time
hereafter in force, that may affect the covenants or the performance of this
Indenture; and the Issuer (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the Indenture Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

            SECTION 5.15 Action on Notes. The Indenture Trustee's right to seek
and recover judgment on the Notes or under this Indenture shall not be affected
by the seeking, obtaining or application of any other relief under or with
respect to this Indenture. Neither the lien of this Indenture nor any rights or
remedies of the Indenture Trustee or the Noteholders shall be impaired by the
recovery of any judgment by the Indenture Trustee against the Issuer or by the
levy of any execution under such judgment upon any portion of the Indenture
Trust Estate or upon any of the assets of the


                                       39
<PAGE>

Issuer. Any money or property collected by the Indenture Trustee shall be
applied in accordance with Section 5.4(b).

            SECTION 5.16 Performance and Enforcement of Certain Obligations.

      (a) Promptly following a request from the Indenture Trustee to do so and
at the Administrator's expense, the Issuer shall take all such lawful action as
the Indenture Trustee may request to compel or secure the performance and
observance by the Seller, the Student Loan Marketing Association, the
Administrator and the Servicer, as applicable, of each of their obligations to
the Issuer, whether directly or by assignment, under or in connection with the
Sale Agreement, the Purchase Agreement, the Administration Agreement and the
Servicing Agreement, respectively, in accordance with the terms thereof, and to
exercise any and all rights, remedies, powers and privileges lawfully available
to the Issuer under or in connection with the Sale Agreement, the Purchase
Agreement, the Administration Agreement and the Servicing Agreement, as the case
may be, to the extent and in the manner directed by the Indenture Trustee,
including the transmission of notices of default on the part of the Seller, the
Student Loan Marketing Association, the Administrator or the Servicer thereunder
and the institution of legal or administrative actions or proceedings to compel
or secure performance by the Seller, the Student Loan Marketing Association, the
Administrator or the Servicer of each of their obligations under the Sale
Agreement, the Purchase Agreement, the Administration Agreement and the
Servicing Agreement, respectively.

      (b) If an Event of Default has occurred and is continuing, the Indenture
Trustee may, and at the written direction of the Noteholders of 66-2/3% of the
Outstanding Amount of the Notes shall, exercise all rights, remedies, powers,
privileges and claims of the Issuer against the Seller, the Student Loan
Marketing Association, the Administrator or the Servicer under or in connection
with the Sale Agreement, the Purchase Agreement, the Administration Agreement
and the Servicing Agreement, respectively, including the right or power to take
any action to compel or secure performance or observance by the Seller, the
Student Loan Marketing Association, the Administrator or the Servicer of each of
their obligations to the Issuer thereunder, whether directly or by assignment,
and to give any consent, request, notice, direction, approval, extension or
waiver under the Sale Agreement, the Purchase Agreement, the Administration
Agreement and the Servicing Agreement, respectively, and any right of the Issuer
to take such action shall be suspended.

                                   ARTICLE VI

                              The Indenture Trustee

            SECTION 6.1 Duties of Indenture Trustee. (a) If an Event of Default
has occurred and is continuing, the Indenture Trustee shall exercise the rights
and powers vested in it by this Indenture and use the same degree of care and
skill in their exercise as a prudent person would exercise or use under the
circumstances in the conduct such person's own affairs.

      (b) Except during the continuance of an Event of Default:

            (i) the Indenture Trustee undertakes to perform such duties and only
such duties as are specifically set forth in this Indenture and no implied
covenants or obligations shall be read into this Indenture against the Indenture
Trustee; and

            (ii) in the absence of bad faith on its part, the Indenture Trustee
may conclusively rely, as to the truth of the statements and the correctness of
the opinions expressed therein, upon certificates or opinions furnished to the
Indenture Trustee and conforming to the requirements of this Indenture;
provided, however, that the Indenture Trustee shall examine the certificates and
opinions to determine whether or not they conform to the requirements of this
Indenture.

      (c) The Indenture Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:

            (i) this paragraph does not limit the effect of paragraph (b) of
this Section;

            (ii) the Indenture Trustee shall not be liable for any error of
judgment made in good faith by a Responsible Officer unless it is proved that
the Indenture Trustee was negligent in ascertaining the pertinent facts; and


                                       41
<PAGE>

            (iii) the Indenture Trustee shall not be liable with respect to any
action it takes or omits to take in good faith in accordance with a direction
received by it pursuant to Section 5.11.

      (d) The Indenture Trustee shall not be liable for interest on any money
received by it except as the Indenture Trustee may agree in writing with the
Issuer.

      (e) Money held in trust by the Indenture Trustee need not be segregated
from other funds except to the extent required by law or the terms of this
Indenture or the other Basic Documents.

      (f) No provision of this Indenture shall require the Indenture Trustee to
expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder or in the exercise of any of its
rights or powers, if it shall have reasonable grounds to believe that repayments
of such funds or adequate indemnity satisfactory to it against any loss,
liability or expense is not reasonably assured to it.

      (g) Except as expressly provided in the Basic Documents, the Indenture
Trustee shall have no obligation to administer, service or collect the Trust
Student Loans or to maintain, monitor or otherwise supervise the administration,
servicing or collection of the Trust Student Loans.

      (h) In the event that the Indenture Trustee is the Paying Agent or the
Note Registrar, the rights and protections afforded to the Indenture Trustee
pursuant to this Indenture shall also be afforded to the Indenture Trustee in
its capacity as Paying Agent or Note Registrar.

            (i) Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Indenture Trustee
shall be subject to the provisions of this Section and to the provisions of the
TIA.

            SECTION 6.2 Rights of Indenture Trustee. The Indenture Trustee may
rely on any document believed by it to be genuine and to have been signed or
presented by the proper Person. The Indenture Trustee need not investigate any

                                       42
<PAGE>

      (b) Before the Indenture Trustee acts or refrains from acting, it may
require and shall be entitled to receive an Officers' Certificate of the Issuer
and/or an Opinion of Counsel. The Indenture Trustee shall not be liable for any
action it takes or omits to take in good faith in reliance on such Officers'
Certificate or Opinion of Counsel.

      (c) The Indenture Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents or attorneys or a custodian or nominee, and the Indenture Trustee shall
not be responsible for any misconduct or negligence on the part of, or for the
supervision of, any such agent, attorney, custodian or nominee appointed with
due care by it hereunder.

      (d) The Indenture Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within its
rights or powers; provided, however, that the Indenture Trustee's conduct does
not constitute willful misconduct, negligence or bad faith.

      (e) The Indenture Trustee may consult with counsel, and the advice or
opinion of counsel with respect to legal matters relating to this Indenture and
the Notes shall be full and complete authorization and protection from liability
in respect to any action taken, omitted or suffered by it hereunder in good
faith and in accordance with the advice or opinion of such counsel.

            SECTION 6.3 Individual Rights of Indenture Trustee. The Indenture
Trustee in its individual or any other capacity may become the owner or pledgee
of Notes and may otherwise deal with the Issuer or its Affiliates with the same
rights it would have if it were not Indenture Trustee. Any Paying Agent, Note
Registrar, co-registrar or co-paying agent may do the same with like rights.
However, the Indenture Trustee must comply with Sections 6.11 and 6.12.

            SECTION 6.4 Indenture Trustee's Disclaimer. The Indenture Trustee
shall not be responsible for and makes no representation as to the validity or
adequacy of this Indenture or the Notes, it shall not be accountable for the
Issuer's use of the proceeds from the Notes, and it shall not be responsible for
any statement of the Issuer in the Indenture or in any document issued in
connection with the sale of the Notes or in the Notes other than the Indenture
Trustee's certificate of authentication.


                                       43
<PAGE>

            SECTION 6.5 Notice of Defaults; Seller Insolvency. (a) If a Default
occurs and is continuing and if it is either actually known or written notice of
the existence thereof has been delivered to a Responsible Officer of the
Indenture Trustee, the Indenture Trustee shall mail notice of the Default to
each Noteholder within 90 days and to each Rating Agency as soon as practicable
within 30 days after it occurs. Except in the case of a Default in payment of
principal of or interest on any Note (including payments pursuant to the
mandatory redemption provisions of such Note), the Indenture Trustee may
withhold the notice if and so long as a committee of its Responsible Officers in
good faith determines that withholding the notice is in the interests of
Noteholders. Except as provided in the first sentence of this Section 6.5(a), in
no event shall the Indenture Trustee be deemed to have knowledge of a Default or
an Event of Default.

      (b) If the Indenture Trustee receives notice from the Eligible Lender
Trustee of the occurrence of an Insolvency Event with respect to the Seller
pursuant to Section 9.2 of the Trust Agreement, the Indenture Trustee shall give
prompt written notice to the Noteholders of the occurrence of such event and of
the effect of such event under such Section 9.2. Upon termination of the Trust
pursuant to such Section 9.2, the Indenture Trustee shall, if so directed by the
Eligible Lender Trustee, sell the Trust Estate (other than the Trust Accounts)
in a commercially reasonable manner and on commercially reasonable terms. The
proceeds of any such sale shall be treated as collections under the
Administration Agreement.

            SECTION 6.6 Reports by Indenture Trustee to Noteholders. The
Indenture Trustee shall deliver to each Noteholder (and to each Person who was a
Noteholder at any time during the applicable calendar year) such information as
may be required to enable such holder to prepare its Federal and state income
tax returns. Within 60 days after each December 31 beginning with the December
31 following the date of this Indenture, the Indenture Trustee shall mail to
each Noteholder a brief report as of such December 31 that complies with TIA ss.
313(a) if required by said section. The Indenture Trustee shall also comply with
TIA ss. 313(b). A copy of each such report required pursuant to TIA ss. 313(a)
or (b) shall, at the time of such transaction to Noteholders, be filed by the
Indenture Trustee with the Commission and with each securities exchange, if any,
upon which the Notes are listed, provided that the Issuer has previously
notified the Indenture Trustee of such listing.


                                       44
<PAGE>

            SECTION 6.7 Compensation and Indemnity. The Issuer shall cause the
Seller to pay to the Indenture Trustee reasonable compensation for its services
in accordance with a separate agreement between the Seller and the Indenture
Trustee and shall cause the Seller to reimburse the Indenture Trustee for all
reasonable out-of-pocket expenses incurred or made by it as provided in such
separate agreement. The Indenture Trustee's compensation shall not be limited by
any law on compensation of a trustee of an express trust. The Issuer shall cause
the Administrator to indemnify the Indenture Trustee and its directors,
officers, employees and agents against any and all loss, liability or expense
(including attorneys' fees) incurred by it in connection with the administration
of this trust and the performance of its duties hereunder and under the other
Basic Documents. The Indenture Trustee shall notify the Issuer and the
Administrator promptly of any claim for which it may seek indemnity. Failure by
the Indenture Trustee to so notify the Issuer and the Administrator shall not
relieve the Issuer or the Administrator of its obligations hereunder and under
the other Basic Documents. The Issuer shall cause the Administrator to defend
the claim and the Administrator shall not be liable for the legal fees and
expenses of the Indenture Trustee after it has assumed such defense; provided,
however, that, in the event that there may be a conflict between the positions
of the Indenture Trustee and the Administrator in conducting the defense of such
claim, the Indenture Trustee shall be entitled to separate counsel acceptable to
it in its sole discretion the reasonable fees and expenses of which shall be
paid by the Administrator on behalf of the Issuer. Neither the Issuer nor the
Administrator need reimburse any expense or indemnify against any loss,
liability or expense incurred by the Indenture Trustee through the Indenture
Trustee's own willful misconduct, negligence or bad faith.

            The Issuer's payment obligations to the Indenture Trustee pursuant
to this Section shall survive the discharge of this Indenture. When the
Indenture Trustee incurs expenses after the occurrence of a Default specified in
Section 5.1(iv) or (v) with respect to the Issuer, the expenses are intended to
constitute expenses of administration under Title 11 of the United States Code
or any other applicable Federal or state bankruptcy, insolvency or similar law.

            SECTION 6.8 Replacement of Indenture Trustee. No resignation or
removal of the Indenture Trustee and no appointment of a successor Indenture
Trustee shall become effective until the acceptance of appointment by the
successor Indenture Trustee pursuant to this Section 6.8. The Indenture Trustee
may resign at any time by so notifying the Issuer. The Noteholders of a majority
in Outstanding Amount of the


                                       45
<PAGE>

Notes may remove the Indenture Trustee by so notifying the Indenture Trustee and
may appoint a successor Indenture Trustee. The Issuer shall remove the Indenture
Trustee if:

            (i)   the Indenture Trustee fails to comply with Section 6.11;

            (ii)  an Insolvency Event occurs with respect to the Indenture
                  Trust- ee;

            (iii) a receiver or other public officer takes charge of the
                  Indenture Trustee or its property; or

            (iv)  the Indenture Trustee otherwise becomes incapable of acting.

            If the Indenture Trustee resigns or is removed or if a vacancy
exists in the office of Indenture Trustee for any reason (the Indenture Trustee
in such event being referred to herein as the retiring Indenture Trustee), the
Issuer shall promptly appoint a successor Indenture Trustee.

            A successor Indenture Trustee shall deliver a written acceptance of
its appointment to the retiring Indenture Trustee and to the Issuer. Thereupon
the resignation or removal of the retiring Indenture Trustee shall become
effective, and the successor Indenture Trustee shall have all the rights, powers
and duties of the Indenture Trustee under this Indenture. The successor
Indenture Trustee shall mail a notice of its succession to Noteholders. The
retiring Indenture Trustee shall promptly transfer all property held by it as
Indenture Trustee to the successor Indenture Trustee.

            If a successor Indenture Trustee does not take office within 60 days
after the retiring Indenture Trustee resigns or is removed, the retiring
Indenture Trustee, the Issuer or the Noteholders of a majority in Outstanding
Amount of the Notes may petition any court of competent jurisdiction for the
appointment of a successor Indenture Trustee. The successor Indenture Trustee
shall give notice of its appointment as successor Indenture Trustee to the
Rating Agencies.

            If the Indenture Trustee fails to comply with Section 6.11, any
Noteholder may petition any court of competent jurisdiction for the removal of
the Indenture Trustee and the appointment of a successor Indenture Trustee.


                                       46
<PAGE>

            Notwithstanding the replacement of the Indenture Trustee pursuant to
this Section, the Issuer's and the Administrator's obligations under Section 6.7
shall continue for the benefit of the retiring Indenture Trustee.

            SECTION 6.9 Successor Indenture Trustee by Merger. If the Indenture
Trustee consolidates with, merges or converts into, or transfers all or
substantially all its corporate trust business or assets to, another corporation
or banking association, the resulting, surviving or transferee corporation
without any further act shall be the successor Indenture Trustee, provided that
such corporation or banking association shall be otherwise qualified and
eligible under Section 6.11. The Indenture Trustee shall provide the Rating
Agencies prior written notice of any such transaction.

            In case at the time such successor or successors by merger,
conversion or consolidation to the Indenture Trustee shall succeed to the trusts
created by this Indenture any of the Notes shall have been authenticated but not
delivered, any such successor to the Indenture Trustee may adopt the certificate
of authentication of any predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been
authenticated, any successor to the Indenture Trustee may authenticate such
Notes either in the name of any predecessor hereunder or in the name of the
successor to the Indenture Trustee; and in all such cases such certificates
shall have the full force which it is anywhere in the Notes or in this Indenture
provided that the certificate of the Indenture Trustee shall have.

            SECTION 6.10 Appointment of Co-Trustee or Separate Trustee. (a)
Notwithstanding any other provisions of this Indenture, at any time, for the
purpose of meeting any legal requirement of any jurisdiction in which any part
of the Indenture Trust Estate may at the time be located, the Indenture Trustee
shall have the power and may execute and deliver all instruments to appoint one
or more Persons to act as a co-trustee or co-trustees, or separate trustee or
separate trustees, of all or any part of the Indenture Trust Estate, and to vest
in such Person or Persons, in such capacity and for the benefit of the
Noteholders, such title to the Indenture Trust Estate, or any part hereof, and,
subject to the other provisions of this Section, such powers, duties,
obligations, rights and trusts as the Indenture Trustee may consider necessary
or desirable. No such appointment shall relieve the Indenture Trustee of its
obligations hereunder. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
6.11 and no notice to


                                       47
<PAGE>

Noteholders of the appointment of any co-trustee or separate trustee shall be
required under Section 6.8 hereof.

      (b) Every 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 Indenture Trustee shall be conferred or imposed upon and exercised or
performed by the Indenture 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 Indenture 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 Indenture 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
Indenture Trust Estate or any portion thereof in any such jurisdiction) shall be
exercised and performed singly by such separate trustee or co-trustee, but
solely at the direction of the Indenture Trustee;

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

            (iii) the Indenture Trustee may at any time accept the resignation
of or remove any separate trustee or co-trustee.

      (c) Any notice, request or other writing given to the Indenture 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 Indenture and
the conditions of this Article VI. 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
Indenture Trustee or separately, as may be provided therein, subject to all the
provisions of this Indenture, specifically including every provision of this
Indenture relating to the conduct of, affecting the liability of, or affording
protection to, the Indenture Trustee. Every such instrument shall be filed with
the Indenture Trustee.

      (d) Any separate trustee or co-trustee may at any time constitute the
Indenture Trustee, its agent or attorney-in-fact with full power and authority,
to the


                                       48
<PAGE>

extent not prohibited by law, to do any lawful act under or in respect of this
Indenture 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
Indenture Trustee, to the extent permitted by law, without the appointment of a
new or successor trustee.

            SECTION 6.11 Eligibility; Disqualification. The Indenture Trustee
shall at all times satisfy the requirements of TIA ss. 310(a) and the
requirements of an "eligible lender" under 20 USC ss.1085(d). The Indenture
Trustee shall have a combined capital and surplus of at least $50,000,000 as set
forth in its most recent published annual report of condition and it shall have
a long-term senior unsecured debt rating of not less than investment grade by
each of the Rating Agencies. The Indenture Trustee shall comply with TIA ss.
310(b), including the optional provision permitted by the second sentence of TIA
ss. 310(b)(9); provided, however, that there shall be excluded from the
operation of TIA ss. 310(b)(1) any indenture or indentures under which other
securities of the Issuer are outstanding if the requirements for such exclusion
set forth in TIA ss. 310(b)(1) are met.

            SECTION 6.12 Preferential Collection of Claims Against Issuer. The
Indenture Trustee shall comply with TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). An Indenture Trustee who has resigned or
been removed shall be subject to TIA ss. 311(a) to the extent indicated.

                                   ARTICLE VII

                         Noteholders' Lists and Reports

            SECTION 7.1 Issuer To Furnish Indenture Trustee Names and Addresses
of Noteholders. The Issuer will furnish or cause to be furnished to the
Indenture Trustee (a) not more than five days after the earlier of (i) each
Record Date and (ii) three months after the last Record Date, a list, in such
form as the Indenture Trustee may reasonably require, of the names and addresses
of the Noteholders as of such Record Date, (b) at such other times as the
Indenture Trustee may request in writing, within 30 days after receipt by the
Issuer of any such request, a list of similar form and content as of a date not
more than 10 days prior to the time such list is furnished; provided, however,

pursuant to the Administration Agreement as provided in this Indenture. Except

<PAGE>

            (i) the Noteholders' Interest Distribution Amount, to the
Noteholders in an amount equal to the accrued and unpaid interest on the Notes
at the respective Note Rates; provided that if there are not sufficient funds
received to pay the entire amount of accrued and unpaid interest then due on the
Notes at the respective Note Rates, the amounts so received shall be applied to
the payment of such interest on the Notes on a pro rata basis;

            (ii) the Noteholders' Principal Distribution Amount, to the
Noteholders of the Class A-1 Notes until the Outstanding Amount of the Class A-1

of moneys deposited in the Trust Accounts shall be deposited by the Indenture
Trustee in the Collection Account, and any loss resulting from such investments
shall be charged to such Trust Account. The Issuer will not direct the Indenture
Trustee to make any investment of any funds or to sell any investment held in
any of the Trust Accounts unless the security interest granted and perfected in
such account will continue to be perfected in such investment or the proceeds of
such sale, in either case without any further action by any Person, and, in
connection with any direction to the Indenture Trustee to make any such
investment or sale, if requested by the Indenture Trustee, the Issuer shall

not as trustee, in accordance with their terms.

      (c) If (i) the Issuer shall have failed to give investment directions for
any funds on deposit in the Trust Accounts to the Indenture Trustee by 10:00
a.m. Eastern Time (or such other time as may be agreed by the Issuer and
Indenture Trustee) on any Business Day; or (ii) a Default shall have occurred
and be continuing with respect to the Notes but the Notes shall not have been
declared due and payable pursuant to Section 5.2, or, if such Notes shall have
been declared due and payable following an Event of Default, amounts collected
or receivable from the Indenture Trust Estate are being applied in accordance
with Section 5.5 as if there had not been such a declaration; then the Indenture
Trustee shall invest and reinvest funds in the Trust Accounts in the Eligible
Investments described in clause (d) of the definition thereof.

instruments to release property from the lien of this Indenture, or convey the
Indenture Trustee's interest in the same, in a manner and under circumstances
that are not inconsistent with the provisions of this Indenture. No party

Article VIII shall be bound to ascertain the Indenture Trustee's authority,
inquire into the satisfaction of any conditions precedent or see to the

any other Person entitled thereto any funds then on deposit in the Trust
Accounts. The Indenture Trustee shall release property from the lien of this
Indenture pursuant to this Section 8.4(b) only upon receipt of an Issuer Request
accompanied by an Officers' Certificate of the Issuer, an Opinion of Counsel and
(if required by the TIA) Independent Certificates in accordance with TIA ss.ss.
314(c) and 314(d)(1) meeting the applicable requirements of Section 11.1.

and the Indenture Trustee shall also require, except in connection with any
action contemplated by Section 8.4(c), as a condition to such action, an Opinion
of Counsel, in form and substance satisfactory to the Indenture Trustee, stating
the legal effect of any such action, outlining the steps required to complete
the same, and concluding that all conditions precedent to the taking of such
action have been complied with and such action will not materially and adversely
impair the security for the Notes or the rights of the Noteholders in
contravention of the provisions of this Indenture; provided, however, that such
Opinion of Counsel shall not be required to express an opinion as to the fair
value of the Indenture Trust Estate. Counsel rendering any such opinion may
rely, without independent investigation, on the accuracy and validity of any
certificate or other instrument delivered to the Indenture Trustee in connection
with any such action.

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.

            SECTION 9.2 Supplemental Indentures with Consent of Noteholders. The
Issuer and the Indenture Trustee, when authorized by an Issuer Order, also may,

thereof (or, in the case of redemption, on or after the Redemption Date);

Indenture.

            It shall not be necessary for any Act of Noteholders under this
Section to approve the particular form of any proposed supplemental indenture,

Indenture or otherwise.

            SECTION 9.4 Effect of Supplemental Indenture. Upon the execution of

Indenture Trustee in exchange for Outstanding Notes.

            Notice of redemption of the Notes shall be given by the Indenture
Trustee in the name and at the expense of the Issuer. Failure to give notice of
redemption, or any defect therein, to any Noteholder of any Note shall not

thereof to be redeemed shall on the Redemption Date become due and payable at
the Redemption Price and (unless the Issuer shall default in the payment of the

            Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this indenture shall include:

            (i) a statement that each signatory of such certificate or opinion

certifying or stating the opinion of any signer thereof as to the matters
described in clause (i) above, the Issuer shall also deliver to the Indenture
Trustee an Independent Certificate as to the same matters, if the fair value to
the Issuer of the securities to be so deposited and of all other such securities
made the basis of any such withdrawal or release since the commencement of the
then-current fiscal year of the Issuer, as set forth in the certificates
delivered pursuant to clause (i) above and this clause (ii), is 10% or more of
the Outstanding Amount of the Notes, but such a certificate need not be
furnished with respect to any securities so deposited, if the fair value thereof
to the Issuer as set forth in the related Officers' Certificate is less than
$25,000 or less than one percent of the Outstanding Amount of the Notes.

            (iii) Other than any property released as contemplated by clause (v)
below, whenever any property or securities are to be released from the lien of
this Indenture, the Issuer shall also furnish to the Indenture Trustee an
Officers' Certificate


                                       62
<PAGE>

of the Issuer certifying or stating the opinion of each person signing such
certificate as to the fair value (within 90 days of such release) of the
property or securities proposed to be released and stating that in the opinion
of such person the proposed release will not impair the security under this
Indenture in contravention of the provisions hereof.

            (iv) Whenever the Issuer is required to furnish to the Indenture
Trustee an Officers' Certificate of the Issuer certifying or stating the opinion
of any signer thereof as to the matters described in clause (iii) above, the
Issuer shall also furnish to the Indenture Trustee an Independent Certificate as
to the same matters if the fair value of the property or securities and of all
other property, other than property as contemplated by clause (v) below, or
securities released from the lien of this Indenture since the commencement of
the then-current calendar year, as set forth in the certificates required by
clause (iii) above and this clause (iv), equals 10% or more of the Outstanding
Amount of the Notes, but such certificate need not be furnished in the case of
any release of property or securities if the fair value thereof as set forth in
the related Officers' Certificate is less than $25,000 or less than one percent
of the then Outstanding Amount of the Notes.

            (v) Notwithstanding Section 2.9 or any other provision of this
Section, the Issuer may, without compliance with the requirements of the other
provisions of this Section, (A) collect, liquidate, sell or otherwise dispose of
Trust Student Loans as and to the extent permitted or required by the Basic
Documents, (B) make cash payments out of the Trust Accounts as and to the extent
permitted or required by the Basic Documents and (C) convey to the Seller, the
Servicer or another eligible lender those specified Trust Student Loans as and
to the extent permitted or required by and in accordance with Section 8.4(c)
hereof and Section 6 of the Sale Agreement, Section 3.5 of the Servicing
Agreement or Section 3.11E of the Servicing Agreement, respectively, so long as
the Issuer shall deliver to the Indenture Trustee every six months, commencing
October 25, 2000, an Officers' Certificate of the Issuer stating that all the
dispositions of Collateral described in clauses (A), (B) or (C) above that
occurred during the immediately preceding six calendar months were in the
ordinary course of the Issuer's business and that the proceeds thereof were
applied in accordance with the Basic Documents.

      SECTION 11.2 Form of Documents Delivered to Indenture Trustee. In any case
where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified
by, or covered


                                       63
<PAGE>

by the opinion of, only one such Person, or that they be so certified or covered
by only one document, but one such Person may certify or give an opinion with
respect to some matters, and one or more other such Persons as to other matters,
and any such Person may certify or give an opinion as to such matters in one or
several documents.

            Any certificate or opinion of an Authorized Officer of the Issuer
may be based, insofar as it relates to legal matters, upon a certificate or
opinion of, or representations by, counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the certificate or opinion or
representations with respect to the matters upon which his certificate or
opinion is based are erroneous. Any such certificate of an Authorized Officer or
Opinion of Counsel may be based, insofar as it relates to factual matters, upon
a certificate or opinion of, or representations by, an officer or officers of
the Servicer, the Seller, the Issuer or the Administrator, stating that the
information with respect to such factual matters is in the possession of the
Servicer, the Seller, the Issuer or the Administrator, unless such counsel
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to such matters are erroneous.

            Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this indenture, they may, but need not, be consolidated and
form one instrument.

            Whenever in this Indenture, in connection with any application or
certificate or report to the Indenture Trustee, it is provided that the Issuer
shall deliver any document as a condition of the granting of such application,
or as evidence of the Issuer's compliance with any term hereof, it is intended
that the truth and accuracy, at the time of the granting of such application or
at the effective date of such certificate or report (as the case may be), of the
facts and opinions stated in such document shall in such case be conditions
precedent to the right of the Issuer to have such application granted or to the
sufficiency of such certificate or report. The foregoing shall not, however, be
construed to affect the Indenture Trustee's right to rely upon the truth and
accuracy of any statement or opinion contained in any such document as provided
in Article VI.

            SECTION 11.3 Acts of Noteholders. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Noteholders may be embodied in and
evidenced by one or


                                       64
<PAGE>

more instruments of substantially similar tenor signed by such Noteholders in
person or by agents duly appointed in writing; and except as herein otherwise
expressly provided such action shall become effective when such instrument or
instruments are delivered to the Indenture Trustee, and, where it is hereby
expressly required, to the Issuer. Such instrument or instruments (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Noteholders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Indenture and (subject to Section 6.1)
conclusive in favor of the Indenture Trustee and the Issuer, if made in the
manner provided in this Section.

      (b) The fact and date of the execution by any person of any such
instrument or writing may be proved in any manner that the Indenture Trustee
deems sufficient.

      (c) The ownership of Notes shall be proved by the Note Register.

      (d) Any request, demand, authorization, direction, notice, consent, waiver
or other action by the Noteholder of any Notes shall bind the Noteholder of
every Note issued upon registration of transfer thereof or in exchange therefor
or in lieu thereof, in respect of anything done, omitted or suffered to be done
by the Indenture Trustee or the Issuer in reliance thereon, whether or not
notation of such action is made upon such Note.

      SECTION 11.4 Notices, etc., to Indenture Trustee, Issuer and Rating
Agencies. Any request, demand, authorization, direction, notice, consent, waiver
or Act of Noteholders or other documents provided or permitted by this Indenture
shall be in writing and if such request, demand, authorization, direction,
notice, consent, waiver or Act of Noteholders is to be made upon, given or
furnished to or filed with:

      (a) The Indenture Trustee by any Noteholder, the Servicer, the
Administrator or by the Issuer shall be sufficient for every purpose hereunder
if made, given, furnished or filed in writing to or with the Indenture Trustee
at its Corporate Trust Office, or

      (b) The Issuer by the Indenture Trustee or by any Noteholder shall be
sufficient for every purpose hereunder if in writing and mailed, first-class,
postage prepaid, to the Issuer addressed to: SLM Student Loan Trust 2000-3, in
care of Chase Manhattan


                                       65

Bank Delaware, 1201 Market Street, Wilmington, Delaware 19801-1167, Attention:
Corporate Trust Department; with copies to The Chase Manhattan Bank, 450 West
33rd Street 15th Fl., New York, New York 10001, Attention: Structured Finance
Services; 11600 Sallie Mae Drive, Reston, VA 20193, Attention: Director,
Corporate Finance Operations, or any other address previously furnished in
writing to the Indenture Trustee by the Issuer or the Administrator. The Issuer
shall promptly transmit any notice received by it from the Noteholders to the
Indenture Trustee.

            Notices required to be given to the Rating Agencies by the Issuer,
the Indenture Trustee or the Eligible Lender Trustee shall be in writing,
personally delivered or mailed by certified mail, return receipt requested, to
(i) in the case of Moody's, at the following address: Moody's, ABS Monitoring
Department, 99 Church Street, New York, New York 10007, (ii) in the case of
Standard & Poor's, at the following address: Standard & Poor's, 55 Water Street,
New York, New York 10041-0003, Attention of Asset Backed Surveillance
Department, and (iii) in the case of Fitch, at the following address: One State
Street Plaza, New York, New York 10004, Attention Municipal Structured Finance
Group; or as to each of the foregoing, at such other address as shall be
designated by written notice to the other parties.

            SECTION 11.5 Notices to Noteholders; Waiver. Where this Indenture
provides for notice to Noteholders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class, postage prepaid to each Noteholder affected by such
event, at his address as it appears on the Note Register, not later than the
latest date, and not earlier than the earliest date, prescribed for the giving
of such notice. In any case where notice to Noteholders is given by mail,
neither the failure to mail such notice nor any defect in any notice so mailed
to any particular Noteholder shall affect the sufficiency of such notice with
respect to other Noteholders, and any notice that is mailed in the manner herein
provided shall conclusively be presumed to have been duly given.

            Where this Indenture provides for notice in any manner, such notice
may be waived in writing by any Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Noteholders shall be filed with the Indenture
Trustee but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such a waiver.


                                       66
<PAGE>

            In case, by reason of the suspension of regular mail service as a
result of a strike, work stoppage or similar activity, it shall be impractical
to mail notice of any event to Noteholders when such notice is required to be
given pursuant to any provision of this Indenture, then any manner of giving
such notice as shall be satisfactory to the Indenture Trustee shall be deemed to
be a sufficient giving of such notice.

            Where this Indenture provides for notice to the Rating Agencies,
failure to give such notice shall not affect any other rights or obligations
created hereunder, and shall not under any circumstance constitute a Default.

            SECTION 11.6 Alternate Payment and Notice Provisions.
Notwithstanding any provision of this Indenture or any of the Notes to the
contrary, the Issuer may enter into any agreement with any Noteholder providing
for a method of payment, or notice by the Indenture Trustee or any Paying Agent
to such Noteholder, that is different from the methods provided for in this
Indenture for such payments or notices. The Issuer will furnish to the Indenture
Trustee a copy of each such agreement and the Indenture Trustee will cause
payments to be made and notices to be given in accordance with such agreements.

            SECTION 11.7 Conflict with Trust Indenture Act. If any provision
hereof limits, qualifies or conflicts with another provision hereof that is
required to be included in this Indenture by any of the provisions of the Trust
Indenture Act, such required provision shall control.

            The provisions of TIA ss.ss. 310 through 317 that impose duties on
any Person (including the provisions automatically deemed included herein unless
expressly excluded by this Indenture) are a part of and govern this Indenture,
whether or not physically contained herein.

            SECTION 11.8 Effect of Headings and Table of Contents. The Article
and Section headings herein and the Table of Contents are for convenience only
and shall not affect the construction hereof.

            SECTION 11.9 Successors and Assigns. All covenants and agreements in
this Indenture and the Notes by the Issuer shall bind its successor and assigns,
whether so expressed or not. All agreements of the Indenture


                                       67
<PAGE>

Trustee in this Indenture shall bind the successors, co-trustees and agents
(excluding any legal representatives or accountants) of the Indenture Trustee.

            SECTION 11.10 Separability. In case any provision in this Indenture
or in the Notes shall be invalid, illegal or unenforceable, the validity,
legality, and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

            SECTION 11.11 Benefits of Indenture. Nothing in this Indenture or in
the Notes, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, and the Noteholders, and any other party
secured hereunder, and any other Person with an ownership interest in any part
of the Indenture Trust Estate, any benefit or any legal or equitable right,
remedy or claim under this Indenture.

            SECTION 11.12 Legal Holidays. In any case where the date on which
any payment is due shall not be a Business Day, then (notwithstanding any other
provision of the Notes or this Indenture) payment need not be made on such date,
but may be made on the next succeeding Business Day with the same force and
effect as if made on the date on which nominally due, and no interest shall
accrue for the period from and after any such nominal date.

            SECTION 11.13 Governing Law. This Indenture shall be construed in
accordance with the laws of the State of New York, without reference to its
conflict of law provisions (other than ss.5-1401 of the New York General
Obligations Law), and the obligations, rights and remedies of the parties
hereunder shall be determined in accordance with such laws.

            SECTION 11.14 Counterparts. This Indenture may be executed in any
number of counterparts, each of which so executed shall be deemed to be an
original, but all such counterparts shall together constitute but one and the
same instrument.

            SECTION 11.15 Recording of Indenture. If this Indenture is subject
to recording in any appropriate public recording offices, such recording is to
be effected by the Issuer and at its expense accompanied by an Opinion of
Counsel (which may be counsel to the Indenture Trustee or any other counsel
reasonably acceptable to the Indenture Trustee) to the effect that such
recording is necessary either for the protection


                                       68
<PAGE>

of the Noteholders or any other Person secured hereunder or for the enforcement
of any right or remedy granted to the Indenture Trustee under this Indenture.

            SECTION 11.16 Trust Obligations. No recourse may be taken, directly
or indirectly, with respect to the obligations of the Issuer, the Seller, the
Administrator, the Servicer, the Eligible Lender Trustee or the Indenture
Trustee on the Notes or under this Indenture or any certificate or other writing
delivered in connection herewith or therewith, against (i) the Indenture Trustee
or the Eligible Lender Trustee in its individual capacity, (ii) any owner of a
beneficial interest in the Issuer or (iii) any partner, owner, beneficiary,
agent, officer, director or employee of the Indenture Trustee or the Eligible
Lender Trustee in its individual capacity, any holder or owner of a beneficial
interest in the Issuer, the Eligible Lender Trustee or the Indenture Trustee or
of any successor or assign thereof in its individual capacity, except as any
such Person may have expressly agreed (it being understood that the Indenture
Trustee and the Eligible Lender Trustee have no such obligations in their
individual capacity) and except that any such partner, owner or beneficiary
shall be fully liable, to the extent provided by applicable law, for any unpaid
consideration for stock, unpaid capital contribution or failure to pay any
installment or call owing to such entity. For all purposes of this Indenture, in
the performance of any duties or obligations of the Issuer hereunder, the
Eligible Lender Trustee shall be subject to, and entitled to the benefits of,
the terms and provisions of Article VI, VII and VIII of the Trust Agreement.

            SECTION 11.17 No Petition. The Indenture Trustee, by entering into
this Indenture, and each Noteholder, by accepting a Note, hereby covenant and
agree that they shall not at any time institute against the Seller or the
Issuer, or join in any institution against the Seller or the Issuer of, any
bankruptcy, reorganization, arrangement, insolvency, receivership or liquidation
proceedings, or other proceedings under any United States Federal or state
bankruptcy or similar law in connection with any obligations relating to the
Notes, this Indenture or any of the other Basic Documents. The foregoing shall
not limit the rights of the Indenture Trustee to file any claim in, or otherwise
take any action with respect to, any insolvency proceeding that was instituted
against the Issuer by any Person other than the Indenture Trustee.

      SECTION 11.18 Inspection. The Issuer agrees that, on reasonable prior
notice, it shall permit any representative of the Indenture Trustee, during the
Issuer's normal business hours, to examine all the books of account, records,
reports, and other papers of the Issuer, to make copies and extracts therefrom,
to cause such books to be audited


                                       69
<PAGE>

by Independent certified public accountants, and to discuss the Issuer's
affairs, finances and accounts with the Issuer's officers, employees, and
Independent certified public accountants, all at such reasonable times and as
often as may be reasonably requested. The Indenture Trustee shall and shall
cause its representatives to hold in confidence all such information obtained
from such examination or inspection except to the extent disclosure may be
required by law (and all reasonable applications for confidential treatment are
unavailing) and except to the extent that the Indenture Trustee may reasonably
determine that such disclosure is consistent with its obligations hereunder.


                                       70

            IN WITNESS WHEREOF, the Issuer and the Indenture Trustee have caused
this Indenture to be duly executed by their respective officers, thereunto duly
authorized and duly attested, all as of the day and year first above written.

                       SLM STUDENT LOAN TRUST [Trust Name}

                FLOATING RATE CLASS A-1 STUDENT LOAN-BACKED NOTES

            SLM Student Loan Trust [Trust Name], a business trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the principal sum of [Note Face Amount] DOLLARS payable on
each Distribution Date in an amount equal to the result obtained by multiplying
(i) a fraction the numerator of which is [Note Face Amount] and the denominator
of which is [Total Class A-1 Note Amount] by (ii) the aggregate amount, if any,
payable to Class A-1 Noteholders on such Distribution Date in respect of
principal of the Notes pursuant to Section 3.1 of the Indenture dated as of
[Indenture Date], among the Issuer, Chase Manhattan Bank Delaware, a Delaware
banking corporation, as Eligible Lender Trustee on behalf of the Issuer, and
Bankers Trust Company, a New York banking corporation, as Indenture Trustee (the
"Indenture Trustee") (capitalized terms used but not defined herein being
defined in Appendix A to the Indenture, which also contains rules as to usage
that shall be applicable herein); provided, however, that the entire unpaid
principal amount of this Note shall be due and payable on the [Final Class A-1
Distribution Date] (the "Class A-1 Maturity Date").

            The Issuer shall pay interest on this Note at the rate per annum
equal to the Class A-1 Rate (as defined on the reverse hereof), on each
Distribution Date until the principal of this Note is paid or made available for
payment, on the principal amount of this Note outstanding on the preceding
Distribution Date (after giving effect to all payments of principal made on the
preceding Distribution Date), subject to certain limitations contained in
Section 3.1 of the Indenture. Interest on this Note shall accrue from and
including the preceding Distribution Date (or, in the case of the first Accrual
Period, the Closing Date) to but excluding the following Distribution Date (each
an "Accrual Period"). Interest shall be calculated on the basis of the actual
number of days elapsed in each Accrual Period divided by 360. Such principal of
and interest on this Note shall be paid in the manner specified on the reverse
hereof.

                                [REVERSE OF NOTE]

            This Note is one of a duly authorized issue of Notes of the Issuer,
designated as its Floating Rate Class A-1 Student Loan-Backed Notes (the "Class
A-1 Notes"), which, together with the Issuer's Floating Rate Class A-2 Student
Loan-Backed Notes (the "Class A-2 Notes" and, together with the Class A-1 Notes,
the "Notes") are issued under and secured by the Indenture, to which Indenture
and all indentures supplemental thereto reference is hereby made for a statement
of the respective rights and obligations thereunder of the Issuer, the Indenture
Trustee and the Noteholders. The Notes are subject to all terms of the
Indenture.

            The Class A-1 Notes are and will be equally and ratably secured by
the Collateral pledged as security therefor as provided in the Indenture. The
Class A-1 Notes are prior in order of principal payment to the Class A-2 Notes
as and to the extent provided in the Indenture.

            Principal of the Class A-1 Notes shall be payable on each
Distribution Date in an amount described on the face hereof. "Distribution Date"
means the 25th day of each January, April, July and October or, if any such date
is not a Business Day, the next succeeding Business Day, commencing [initial
Distribution Date].

            As described on the face hereof, the entire unpaid principal amount
of this Note shall be due and payable on the Class A-1 Maturity Date.
Notwithstanding the foregoing, the entire unpaid principal amount of the Notes
shall be due and payable on the date on which (i) an Event of Default shall have
occurred and be continuing and (ii) the Indenture Trustee or the Noteholders
representing not less than a majority of the Outstanding Amount of the Notes
shall have declared the Notes to be immediately due and payable in the manner
provided in Section 5.2 of the Indenture. All principal payments on the Class
A-1 Notes shall be made pro rata to the Noteholders entitled thereto.

            Interest on the Class A-1 Notes shall be payable on each
Distribution Date on the principal amount outstanding of the Class A-1 Notes
until the principal amount thereof is paid in full, at a rate per annum equal to
the Class A-1 Rate. The "Class A-1 Rate" for each Accrual Period shall be equal
to, in the case of T-Bill Rate denominated Notes, the daily weighted average of
the T-Bill Rates within that Accrual Period plus [specified percentage points],
and, in the case of LIBOR denominated


                                       78
<PAGE>

Notes, Three-Month [or such other designated maturity, as necessary, for the
initial Accrual Period] LIBOR as determined on the second business day before
the beginning of that Accrual Period plus [specified percentage points]%.

            Payments of interest on this Note on each Distribution Date,
together with the installment of principal, if any, to the extent not in full
payment of this Note, shall be made by check mailed to the Person whose name
appears as the Registered Holder of this Note (or one or more Predecessor Notes)
on the Note Register on the Record Date, except that with respect to Notes
registered on the Record Date in the name of the nominee of the Clearing Agency,
unless Definitive Notes have been issued (initially, such nominee to be Cede &
Co.), payments shall be made by wire transfer in immediately available funds to
the account designated by such nominee. Such checks shall be mailed to the
Person entitled thereto at the address of such Person as it appears on the Note
Register as of the applicable Record Date without requiring that this Note be
submitted for notation of payment, and the mailing of such check shall
constitute payment of the amount thereof regardless of whether such check is
returned undelivered. Any reduction in the principal amount of this Note (or any
one or more Predecessor Notes) effected by any payments made on any Distribution
Date shall be binding upon all future Noteholders of this Note and of any Note
issued upon the registration of transfer hereof or in exchange hereof or in lieu
hereof, whether or not noted hereon. If funds are expected to be available, as
provided in the Indenture, for payment in full of the then remaining unpaid
principal amount of this Note on a Distribution Date, then the Indenture
Trustee, in the name of and on behalf of the Issuer, shall notify the Person who
was the Noteholder hereof as of the preceding Record Date by notice mailed no
later than five days prior to such Distribution Date and the amount then due and
payable shall be payable only upon presentation and surrender of this Note at
the Indenture Trustee's Corporate Trust Office or at the office of the Indenture
Trustee's agent appointed for such purposes located in the Borough of Manhattan,
The City of New York.

            The Issuer shall pay interest on overdue installments of interest on
this Note at the Class A-1 Rate to the extent lawful.

            As provided in the Indenture and subject to certain limitations set
forth therein, the transfer of this Note may be registered on the Note Register
upon surrender of this Note for registration of transfer at the office or agency
designated by the Issuer

pursuant to the Indenture, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Indenture Trustee duly
executed by, the Noteholder hereof or his attorney duly authorized in writing,
with such signature guaranteed by an "eligible guarantor institution" meeting
the requirements of the Note Registrar, which requirements include membership or
participation in Securities Transfer Agent's Medallion Program ("STAMP") or such
other "signature guarantee program" as may be determined by the Note Registrar
in addition to, or in substitution for, STAMP (all in accordance with the
Exchange Act), and such other documents as the Indenture Trustee may require,
and thereupon one or more new Notes of authorized denominations and in the same
aggregate principal amount shall be issued to the designated transferee or
transferees. No service charge will be charged for any registration of transfer
or exchange of this Note, but the transferor may be required to pay a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any such registration of transfer or exchange.

            Each Noteholder or Note Owner, by acceptance of a Note or, in the
case of a Note Owner, a beneficial interest in the Note, covenants and agrees
that no recourse may be taken, directly or indirectly, with respect to the
obligations of the Issuer or the Indenture Trustee on the Notes or under the
Indenture or any certificate or other writing delivered in connection therewith,
against (i) the Indenture Trustee or the Eligible Lender Trustee in its
individual capacity, (ii) any owner of a beneficial interest in the Issuer or
(iii) any partner, owner, beneficiary, agent, officer, director or employee of
the Indenture Trustee or the Eligible Lender Trustee in its individual capacity,
any holder or owner of a beneficial interest in the Issuer, the Eligible Lender
Trustee or the Indenture Trustee or of any successor or assign thereof in its
individual capacity, except as any such Person may have expressly agreed (it
being understood that the Indenture Trustee and the Eligible Lender Trustee have
no such obligations in their individual capacity) and except that any such
partner, owner or beneficiary shall be fully liable, to the extent provided by
applicable law, for any unpaid consideration for stock, unpaid capital
contribution or failure to pay any installment or call owing to such entity.

            Each Noteholder or Note Owner, by acceptance of a Note or, in the
case of a Note Owner, a beneficial interest in a Note, covenants and agrees that
by accepting the benefits of the Indenture such Noteholder or Note Owner will
not at any time institute against the Seller or the Issuer, or join in any
institution against the Seller or the Issuer of, any bankruptcy, reorganization,
arrangement, insolvency, receivership or liquidation proceedings or other
proceedings under any United States Federal or state


                                       80

bankruptcy or similar law in connection with any obligations relating to the
Notes, the Indenture or the other Basic Documents.

            Prior to the due presentment for registration of transfer of this
Note, the Issuer, the Indenture Trustee and any agent of the Issuer or the
Indenture Trustee may treat the Person in whose name this Note (as of the day of
determination or as of such other date as may be specified in the Indenture) is
registered as the owner hereof for all purposes whether or not this Note be
overdue, and neither the Issuer, the Indenture Trustee nor any such agent shall
be affected by notice to the contrary.

            The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Noteholders under the Indenture at any time by the
Issuer with the consent of the Noteholders representing a majority of the
Outstanding Amount of all Notes at the time outstanding. The Indenture also
contains provisions permitting the Noteholders representing specified
percentages of the Outstanding Amount of the Notes, on behalf of all the
Noteholders, to waive compliance by the Issuer with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the holder of this Note (or any one of more
Predecessor Notes) shall be conclusive and binding upon such holder and upon all
future holders of this Note and of any Note issued upon registration of transfer
hereof or in exchange hereof or in lieu hereof whether or not notation of such
consent or waiver is made upon this Note. The Indenture also permits the
Indenture Trustee to amend or waive certain terms and conditions set forth in
the Indenture without the consent of holders of the Notes issued thereunder.

            The term "Issuer" as used in this Note includes any successor to the
Issuer under the Indenture.

            The Issuer is permitted by the Indenture, under certain
circumstances, to merge or consolidate, subject to the rights of the Indenture
Trustee and the Noteholders under the Indenture.

            The Notes are issuable only in registered form in denominations as
provided in the Indenture, subject to certain limitations therein set forth.

absolute and unconditional, to pay the principal of and interest on this Note at

beneficiaries, agents, officers, directors, employees or successors or assigns

the Indenture Trustee or the Eligible Lender Trustee in its individual capacity,
any holder or owner of a beneficial interest in the Issuer, the Eligible Lender
Trustee or the Indenture Trustee or of any successor or assign thereof in its
individual capacity, except as any such Person may have expressly agreed (it
being understood that the Indenture Trustee and the Eligible Lender Trustee have
no such obligations in their individual capacity) and except that any such
partner, owner or beneficiary shall be fully liable, to the extent provided by
applicable law, for any unpaid consideration for stock, unpaid capital
contribution or failure to pay any installment or call owing to such entity.

            Each Noteholder or Note Owner, by acceptance of a Note or, in the
case of a Note Owner, a beneficial interest in a Note, covenants and agrees that
by accepting the benefits of the Indenture such Noteholder or Note Owner will
not at any time institute against the Seller or the Issuer, or join in any
institution against the Seller or the Issuer of, any bankruptcy, reorganization,
arrangement, insolvency,

receivership or liquidation proceedings or other proceedings under any United
States Federal or state bankruptcy or similar law in connection with any
obligations relating to the Notes, the Indenture or the other Basic Documents.

            Prior to the due presentment for registration of transfer of this
Note, the Issuer, the Indenture Trustee and any agent of the Issuer or the
Indenture Trustee may treat the Person in whose name this Note (as of the day of
determination or as of such other date as may be specified in the Indenture) is
registered as the owner hereof for all purposes whether or not this Note be
overdue, and neither the Issuer, the Indenture Trustee nor any such agent shall
be affected by notice to the contrary.

            The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Noteholders under the Indenture at any time by the
Issuer with the consent of the Noteholders representing a majority of the
Outstanding Amount of all Notes at the time outstanding. The Indenture also
contains provisions permitting the Noteholders representing specified
percentages of the Outstanding Amount of the Notes, on behalf of all the
Noteholders, to waive compliance by the Issuer with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the holder of this Note (or any one of more
Predecessor Notes) shall be conclusive and binding upon such holder and upon all
future holders of this Note and of any Note issued upon registration of transfer
hereof or in exchange hereof or in lieu hereof whether or not notation of such
consent or waiver is made upon this Note. The Indenture also permits the
Indenture Trustee to amend or waive certain terms and conditions set forth in
the Indenture without the consent of holders of the Notes issued thereunder.

            The term "Issuer" as used in this Note includes any successor to the
Issuer under the Indenture.

            The Issuer is permitted by the Indenture, under certain
circumstances, to merge or consolidate, subject to the rights of the Indenture
Trustee and the Noteholders under the Indenture.

            The Notes are issuable only in registered form in denominations as
provided in the Indenture, subject to certain limitations therein set forth.

State of New York, without reference to its conflict of law provisions, and the
obligations, rights and remedies of the parties hereunder and thereunder shall
be determined in accordance with such laws.

an Event of Default under the Indenture, the Noteholder shall have no claim

           PURCHASE AGREEMENT MASTER SECURITIZATION TERMS NUMBER 1000

      These Purchase Agreement Master Securitization Terms Number 1000 ("Master

repurchase any affected Trust Student Loan not later than 120 days following the
earlier of the date of discovery of such material breach and the date of receipt
of the Guarantor reject transmittal form with respect to such Trust Student
Loan. In the event of such a material breach which is curable by reinstatement
of the Guarantor's guarantee of such Trust Student Loan, unless the material
breach shall have been cured within 360 days following the earlier of the date
of discovery of such material breach and the date of receipt of the Guarantor
reject transmittal form with respect to such Trust Student Loan, Sallie Mae
shall purchase such Trust Student Loan not later than the sixtieth day following
the end of such 360-day period. Sallie Mae shall also remit as provided in
Section 2.6 of the Administration Agreement on the date of purchase of any Trust
Student Loan pursuant to this Section 6 an amount equal to all nonguaranteed

Payments with respect to such Trust Student Loan. In consideration of the
purchase of any such Trust Student Loan pursuant to this Section 6, Sallie Mae
shall remit the Purchase Amount in the manner specified in Section 2.6 of the
Administration Agreement.

      In addition, if any breach of Section 5 hereof by Sallie Mae does not
trigger such purchase obligation but does result in the refusal by a Guarantor
to guarantee all or a portion of the accrued interest (or any obligation of
Funding to repay such interest to a Guarantor), or the loss (including any
obligation of Funding to repay the Department) of Interest Subsidy Payments and
Special Allowance Payments, with respect to any Trust Student Loan affected by
such breach, then Sallie Mae shall reimburse Funding by remitting an amount
equal to the sum of all such nonguaranteed interest amounts and such forfeited
Interest Subsidy Payments or Special Allowance Payments in the manner specified
in Section 2.6 of the Administration Agreement not later than (i) the last day
of the next Collection Period ending not less than 60 days from the date of the
Guarantor's refusal to guarantee all or a portion of accrued interest or loss of
Interest Subsidy Payments or Special Allowance Payments, or (ii) in the case
where Sallie Mae reasonably believes such losses are likely to be collected, not
later than the last day of the next Collection Period ending not less than 360
days from the date of the Guarantor's refusal to guarantee all or a portion of
accrued interest or loss of Interest Subsidy Payments or Special Allowance
Payments. At the time such payment is made, Sallie Mae


                                       12
<PAGE>

capitalized, however, such amounts shall be reimbursed if the borrower
subsequently defaults and such capitalized interest is not paid by the
Guarantor.

last Business Day of any month the aggregate outstanding principal amount of
Trust Student Loans with respect to which claims have been filed with and
rejected by a Guarantor or with respect to which the Servicer determines that
claims cannot be filed pursuant to the Higher Education Act as a result of a
breach by Sallie Mae or the Servicer, exceeds 1% of the Pool Balance, Sallie Mae
(and the Servicer as provided in the Servicing Agreement) shall purchase, within
30 days of a written request of the Eligible Lender Trustee or the Indenture
Trustee, such affected Trust Student Loans in an aggregate principal amount such
that after such purchase the aggregate principal amount of such affected Trust
student Loans is less than 1% of the Pool Balance. The Trust Student Loans to be
purchased by Sallie Mae and the Servicer pursuant to the preceding sentence
shall be based on the date of claim rejection (or the date of notice referred to
in the first sentence of this Section 6) with Trust Student Loans with the
earliest such date to be purchased first.

      In lieu of repurchasing Trust Student Loans pursuant to this Section 6,
Sallie Mae may, at its option, substitute Eligible Loans or arrange for the
substitution of Eligible Loans which are substantially similar on an aggregate
basis as of the date of substitution to the Trust Student Loans for which they
are being substituted with respect to the following characteristics:

            (1)   status (i.e., in-school, grace, deferment, forbearance or
                  repayment),

            (2)   program type (i.e., Unsubsidized Stafford, Subsidized
                  Stafford, Consolidation (pre-1993 vs. post-1993), PLUS or
                  SLS),

            (3)   school type,

            (4)   total return,

            (5)   principal balance, and

            (6)   remaining term to maturity.

      In addition, each substituted Eligible Loan will comply, as of the date of
substitution, with all of the representations and warranties made hereunder. In
choosing Eligible Loans to be substituted pursuant to this Section 6, Sallie Mae
shall make a reasonable determination that the Eligible Loans to be


                                       13
<PAGE>

substituted will not have a material adverse effect on the Noteholders and the
Certificateholders.

      In the event that Sallie Mae elects to substitute Eligible Loans pursuant
to this Section 6, Sallie Mae will remit to the Administrator the amount of any
shortfall between the Purchase Amount of the substituted Eligible Loans and the
Purchase Amount of the Trust Student Loans for which they are being substituted.
Sallie Mae shall also remit to the Administrator an amount equal to all
nonguaranteed interest amounts and forfeited Interest Subsidy Payments and
Special Allowance Payments with respect to the Trust Student Loans in the manner
provided in Section 2.6 of the Administration Agreement. The sole remedy of
Funding, the Eligible Lender Trustee, the Certificateholders and the Noteholders
with respect to a breach by Sallie Mae pursuant to Section 5 hereof shall be to
require Sallie Mae to purchase Trust Student Loans, to reimburse Funding as
provided above or to substitute Student Loans pursuant to this Section. The
Eligible Lender Trustee shall have no duty to conduct any affirmative
investigation as to the occurrence of any condition requiring the purchase of
any Trust Student Loan or the reimbursement for any interest penalty pursuant to
this Section 6.

SECTION 7. OBLIGATION TO REMIT SUBSEQUENT PAYMENTS AND FORWARD COMMUNICATIONS

      (A) Any payment received by Sallie Mae with respect to amounts accrued
      after the Date of the Bill of Sale for any Loan sold to Funding, which
      payment is not reflected in the Loan Transmittal Summary Form, shall be
      received by Sallie Mae in trust for the account of Funding and Sallie Mae
      hereby disclaims any title to or interest in any such amounts. Within two
      (2) business days following the date of receipt, Sallie Mae shall remit to
      Funding an amount equal to any such payments on a list provided by Funding
      identifying the Loans with respect to which such payments were made, the
      amount of each such payment and the date each such payment was received.

      (B) Any written communication received at any time by Sallie Mae with
      respect to any Loan subject to this Purchase Agreement shall be
      transmitted by Sallie Mae to Servicer within two (2) business days of
      receipt. Such communications shall include, but not be limited to,
      letters, notices of death or disability, notices of bankruptcy, forms
      requesting deferment of repayment or loan cancellation, and like
      documents.

SECTION 8. CONTINUING OBLIGATION OF SALLIE MAE


                                       14
<PAGE>

      Sallie Mae shall provide all reasonable assistance necessary for Funding
to resolve account problems raised by any Borrower, the Guarantor or the
Secretary provided such account problems are attributable to or are alleged to
be attributable to (a) an event occurring during the period Sallie Mae owned the
Loan, or (b) a payment made or alleged to have been made to Sallie Mae. Further,
Sallie Mae agrees to execute any financing statements at the request of Funding
in order to reflect Funding's interest in the Loans.

SECTION 9. LIABILITY OF SALLIE MAE; INDEMNITIES

      Sallie Mae shall be liable in accordance herewith only to the extent of
the obligations specifically undertaken by Sallie Mae under this Purchase
Agreement.

      (i) Sallie Mae shall indemnify, defend and hold harmless Funding and the
      Interim Eligible Lender Trustee in its individual capacity and their
      officers, directors, employees and agents from and against any taxes that
      may at any time be asserted against any such Person with respect to the
      transactions contemplated herein and in the other Basic Documents (except
      any such income taxes arising out of fees paid to the Interim Eligible
      Lender Trustee), including any sales, gross receipts, general corporation,
      tangible personal property, privilege or license taxes (but, in the case
      of Funding, not including any taxes asserted with respect to, and as of
      the date of, the sale of the Loans to the Interim Eligible Lender Trustee
      on behalf of Funding, or asserted with respect to ownership of the Trust
      Student Loans) and costs and expenses in defending against the same.

      (ii) Sallie Mae shall indemnify, defend and hold harmless Funding and the
      Interim Eligible Lender Trustee in its individual capacity, and the
      officers, directors, employees and agents of Funding, and the Interim
      Eligible Lender Trustee from and against any and all costs, expenses,
      losses, claims, damages and liabilities arising out of, or imposed upon
      such Person through, Sallie Mae's willful misfeasance, bad faith or gross
      negligence in the performance of its duties under the Purchase Agreement,
      or by reason of reckless disregard of its obligations and duties under the
      Purchase Agreement.

      (iii) Sallie Mae shall be liable as primary obligor for, and shall
      indemnify, defend and hold harmless the Interim Eligible Lender Trustee in
      its individual capacity and its officers, directors, employees and agents
      from and against, all costs, expenses, losses, claims, damages,
      obligations and liabilities arising out of, incurred in connection with or
      relating to the Purchase Agreement, the other Basic Documents, the
      acceptance or performance of the trusts and duties set forth herein and in
      the Sale Agreement or the


                                       15
<PAGE>

      action or the inaction of the Interim Eligible Lender Trustee hereunder,
      except to the extent that such cost, expense, loss, claim, damage,
      obligation or liability: (a) shall be due to the willful misfeasance, bad
      faith or negligence (except for errors in judgment) of the Interim
      Eligible Lender Trustee, (b) shall arise from any breach by the Interim
      Eligible Lender Trustee of its covenants made under any of the Basic
      Documents; or (c) shall arise from the breach by the Interim Eligible
      Lender Trustee of any of its representations or warranties made in its
      individual capacity set forth in these Master Terms or any Purchase
      Agreement. In the event of any claim, action or proceeding for which
      indemnity will be sought pursuant to this paragraph, the Interim Eligible
      Lender Trustee's choice of legal counsel shall be subject to the approval
      of Sallie Mae, which approval shall not be unreasonably withheld.

      Indemnification under this Section shall survive the resignation or
removal of the Interim Eligible Lender Trustee and the termination of these
Master Terms, and shall include reasonable fees and expenses of counsel and
expenses of litigation. If Sallie Mae shall have made any indemnity payments
pursuant to this Section and the Person to or on behalf of whom such payments
are made thereafter shall collect any of such amounts from others, such Person
shall promptly repay such amounts to Sallie Mae, without interest.

SECTION 10. MERGER OR CONSOLIDATION OF, OR ASSUMPTION OF THE OBLIGATIONS OF
            SALLIE MAE

      Any Person (a) into which Sallie Mae may be merged or consolidated, (b)
which may result from any merger or consolidation to which Sallie Mae shall be a
party or (c) which may succeed to the properties and assets of Sallie Mae
substantially as a whole, shall be the successor to Sallie Mae without the
execution or filing of any document or any further act by any of the parties to
this Purchase Agreement; provided, however, that Sallie Mae hereby covenants
that it will not consummate any of the foregoing transactions except upon
satisfaction of the following: (i) the surviving Person, if other than Sallie
Mae, executes an agreement of assumption to perform every obligation of Sallie
Mae under the Purchase Agreement, (ii) immediately after giving effect to such
transaction, no representation or warranty made pursuant to Section 5 shall have
been breached, (iii) the surviving Person, if other than Sallie Mae, shall have
delivered to the Interim Eligible Lender Trustee an Officers' Certificate and an
Opinion of Counsel each stating that such consolidation, merger or succession
and such agreement of assumption comply with this Section and that all
conditions precedent, if any, provided for in this Purchase Agreement relating
to such transaction have been complied with, and that the Rating Agency
Condition shall have been satisfied with respect to such transaction (iv) if
Sallie Mae is not the


                                       16
<PAGE>

surviving entity, Sallie Mae shall have delivered to the Interim Eligible Lender
Trustee an Opinion of Counsel either (A) stating that, in the opinion of such
counsel, all financing statements and continuation statements and amendments
thereto have been executed and filed that are necessary fully to preserve and
protect the interest of Funding and the Interim Eligible Lender Trustee in the
Loans and reciting the details of such filings, or (B) stating that, in the
opinion of such counsel, no such action shall be necessary to preserve and
protect such interests.

SECTION 11. LIMITATION ON LIABILITY OF SALLIE MAE AND OTHERS

      Sallie Mae and any director or officer or employee or agent thereof may
rely in good faith on the advice of counsel or on any document of any kind,
prima facie properly executed and submitted by any Person respecting any matters
arising hereunder (provided that such reliance shall not limit in any way Sallie
Mae's obligations under Section 6.) Sallie Mae shall not be under any obligation
to appear in, prosecute or defend any legal action that shall not be incidental
to its obligations under these Master Terms or any Purchase Agreement, and that
in its opinion may involve it in any expense or liability. Except as provided
herein, the repurchase (or substitution) and reimbursement obligations of Sallie
Mae will constitute the sole remedy available to Funding for uncured breaches;
provided, however, that the information with respect to the Loans listed on the
Bill of Sale may be adjusted in the ordinary course of business subsequent to
the date of the Bill of Sale and to the extent that the aggregate Principal
Balance of the Loans listed on the Bill of Sale is less than the aggregate
Principal Balance stated on the Bill of Sale, Sallie Mae shall remit such amount
to the Interim Eligible Lender Trustee on behalf of Funding. Such reconciliation
payment shall be made from time to time but no less frequently than
semi-annually.

SECTION 12. LIMITATION OF LIABILITY OF INTERIM ELIGIBLE LENDER TRUSTEE

       Notwithstanding anything contained herein to the contrary, these Master
Terms and any Purchase Agreement have been signed by Chase Manhattan Bank
Delaware not in its individual capacity but solely in its capacity as Interim
Eligible Lender Trustee for Funding and in no event shall Chase Manhattan Bank
Delaware in its individual capacity have any liability for the representations,
warranties, covenants, agreements or other obligations of Funding, under these
Master Terms or any Purchase Agreement or in any of the certificates, notices or
agreements delivered pursuant hereto, as to all of which recourse shall be had
solely to the assets of Funding.

SECTION 13. EXPENSES


                                       17
<PAGE>

      Except as otherwise provided herein, each party to these Master Terms or
any Purchase Agreement shall pay its own expense incurred in connection with the
preparation, execution and delivery of these Master Terms and any Purchase
Agreement and the transactions contemplated herein or therein.

SECTION 14. SURVIVAL OF COVENANTS/SUPERSESSION

      All covenants, agreements, representations and warranties made herein and
in or pursuant to any Purchase Agreements executed pursuant to these Master
Terms shall survive the consummation of the purchase of the Loans provided for
in each Purchase Agreement. All covenants, agreements, representations and
warranties made or furnished pursuant hereto by or on behalf of Sallie Mae shall
bind and inure to the benefit of any successors or assigns of Funding and shall
survive with respect to each Loan. Each Purchase Agreement supersedes all
previous agreements and understandings between Funding and Sallie Mae with
respect to the subject matter thereof. These Master Terms and any Purchase
Agreement may be changed, modified or discharged, and any rights or obligations
hereunder may be waived, only by a written instrument signed by a duly
authorized officer of the party against whom enforcement of any such waiver,
change, modification or discharge is sought. The waiver by Funding of any
covenant, agreement, representation or warranty required to be made or furnished
by Sallie Mae or the waiver by Funding of any provision herein contained or
contained in any Purchase Agreement shall not be deemed to be a waiver of any
breach of any other covenant, agreement, representation, warranty or provision
herein contained, nor shall any waiver or any custom or practice which may
evolve between the parties in the administration of the terms hereof or of any
Purchase Agreement, be construed to lessen the right of Funding to insist upon
the performance by Sallie Mae in strict accordance with said terms.

SECTION 15. COMMUNICATION AND NOTICE REQUIREMENTS

      All communications, notices and approvals provided for hereunder shall be
in writing and mailed or delivered to Sallie Mae or Funding, as the case may be,
addressed as set forth in the Purchase Agreement or at such other address as
either party may hereafter designate by notice to the other party. Notice given
in any such communication, mailed to Sallie Mae or Funding by appropriately
addressed registered mail, shall be deemed to have been given on the day
following the date of such mailing.

SECTION 16. FORM OF INSTRUMENTS

      All instruments and documents delivered in connection with these Master
Terms and any Purchase Agreement, and all proceedings to be taken in connection
with these Master Terms and any Purchase Agreement and the transactions
contemplated herein


                                       18
<PAGE>

and therein, shall be in a form as set forth in the attachments hereto, and
Funding shall have received copies of such documents as it or its counsel shall
reasonably request in connection therewith. Any instrument or document which is
substantially in the same form as an Attachment hereto or a recital herein will
be deemed to be satisfactory as to form.

SECTION 17. AMENDMENT

      These Master Terms and any Purchase Agreement may be amended by the
parties thereto without the consent of the related Noteholders or
Certificateholders for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of such Master Terms and
Purchase Agreements or of modifying in any manner the rights of such Noteholders
or Certificateholders; provided that such action will not, in the opinion of
counsel satisfactory to the related Indenture Trustee and Eligible Lender
Trustees, materially and adversely affect the interest of any such Noteholder or
Certificateholder.

      In addition, these Master Terms and any Purchase Agreement may also be
amended from time to time by Sallie Mae, the Interim Eligible Lender Trustee and
Funding, with the consent of the Noteholders of Notes evidencing a majority of
the Outstanding Amount of the Notes and the consent of the Certificateholders of
Certificates evidencing a majority of the Certificate Principal Balance, for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of these Master Terms or any Purchase Agreements 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 time of, collections of
payments with respect to 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 Principal Balance of Certificates, the Noteholders or the
Certificateholders of which are required to consent to any such amendment,
without the consent of all outstanding Noteholders and Certificateholders.

      Promptly after the execution of any such amendment or consent (or, in the
case of the Rating Agencies, five Business Days prior thereto), the Interim
Eligible Lender Trustee shall furnish written notification of the substance of
such amendment or consent to the Indenture Trustee, each Certificateholder, and
each of the Rating Agencies.

      It shall not be necessary for the consent of Certificateholders or
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.


                                       19
<PAGE>

      Prior to the execution of any amendment to these Master Terms, the Interim
Eligible Lender Trustee shall be entitled to receive and rely upon an Opinion of
Counsel stating that execution of such amendment is authorized or permitted by
this Agreement and the Opinion of Counsel referred to in Section 7.1 I(i) of the
Administration 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 18. NONPETITION COVENANTS

      Notwithstanding any prior termination of these Master Terms Sallie Mae and
the Interim Eligible Lender Trustee shall not acquiesce, petition or otherwise
invoke or cause Funding to invoke the process of any court or government
authority for the purpose of commencing or sustaining a case against Funding
under any Federal or state bankruptcy, insolvency or similar law or appointing a
receiver, liquidator, assignees, trustee, custodian, sequestrator or other
similar official of Funding or any substantial part of its property, or ordering
the winding up or liquidation of the affairs of the Funding.

SECTION 19. GOVERNING LAW

      These Master Terms and any Purchase Agreement shall be government by and
construed in accordance with the laws of the State of New York 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.

            In consideration of the Purchase Price, Sallie Mae hereby sells to
      the Interim Eligible Lender Trustee for the benefit of Funding the entire
      right, title and interest of Sallie Mae in the Loans accepted for

            This document shall constitute a Purchase Agreement as referred to

      1074), as official notification to the Guarantor of assignment to the
      Interim Eligible Lender Trustee on behalf of Funding of the Loans on the

            The parties hereto intend that the transfer of Loans described in
      the Bill of Sale and Loan Transmittal Summary Form be, and be construed
      as, a valid sale of such Loans from Sallie Mae to the Interim Eligible
      Lender Trustee for the benefit of Funding. However, in the event that
      notwithstanding the intention of the parties, such transfer is deemed to
      be a transfer for security, then Sallie Mae hereby grants to the Interim
      Eligible Lender Trustee for the benefit of Funding a first priority
      security interest in and to all Loans described in the Bill of Sale and
      Loan Transmittal Summary Form to secure a loan in an amount equal to the
      Purchase Price of such loans.

      with each of the Guarantors with respect to the Trust Student Loans.

SECTION 6. PURCHASE OF TRUST STUDENT LOANS; REIMBURSEMENT

      Each party to this Agreement shall give notice to the other such parties
and to the Servicer, the Administrator and Sallie Mae promptly, in writing, upon
the discovery of any breach of Seller's representations and warranties made
pursuant to Section 5 hereof which has a materially adverse effect on the
interest of the Purchaser in any Trust Student Loan. In the event of such a
material breach which is not curable by reinstatement of the applicable
Guarantor's guarantee of such Trust Student Loan, Seller shall repurchase any
affected Trust Student Loan not later than 120 days following the earlier of the
date of discovery of such material breach and the date of receipt of the
Guarantor reject transmittal form with respect to such Trust Student Loan. In
the event of such a material breach which is curable by reinstatement of the
applicable Guarantor's guarantee of such Trust Student Loan, unless the material
breach shall have been cured within 360 days following the earlier of the date
of discovery of such material breach and the date of receipt of the Guarantor
reject transmittal form with respect to such Trust Student Loan, the Seller
shall purchase such Trust Student Loan not later than the sixtieth day following
the end of such 360-day period. The Seller shall also remit as provided in
Section 2.6 of the Administration Agreement on the date of purchase of any Trust
Student Loan pursuant to this


                                       11
<PAGE>

Section 6 an amount equal to all nonguaranteed interest amounts and forfeited
Interest Subsidy Payments and Special Allowance Payments with respect to such
Trust Student Loan. In consideration of the purchase of any such Trust Student
Loan pursuant to this Section 6, the Seller shall remit the Purchase Amount in
the manner specified in Section 2.6 of the Administration Agreement.

      In addition, if any breach of Section 5 hereof by the Seller does not
trigger such purchase obligation but does result in the refusal by a Guarantor
to guarantee all or a portion of the accrued interest (or any obligation of the
Purchaser to repay such interest to a Guarantor), or the loss (including any
obligation of the Purchaser to repay the Department) of Interest Subsidy
Payments and Special Allowance Payments, with respect to any Trust Student Loan
affected by such breach, then the Seller shall reimburse the Purchaser by
remitting an amount equal to the sum of all such nonguaranteed interest amounts
and such forfeited Interest Subsidy Payments or Special Allowance Payments in
the manner specified in Section 2.6 of the Administration Agreement not later
than (i) the last day of the next Collection Period ending not less than 60 days
from the date of the Guarantor's refusal to guarantee all or a portion of
accrued interest or loss of Interest Subsidy Payments or Special Allowance
Payments, or (ii) in the case where the Seller reasonably believes such losses
are likely to be collected, not later than the last day of the next Collection
Period ending not less than 360 days from the date of the Guarantor's refusal to
guarantee all or a portion of accrued interest or loss of Interest Subsidy
Payments or Special Allowance Payments. At the time such payment is made, the
Seller shall not be required to reimburse the Purchaser for interest that is
then capitalized, however, such amounts shall be reimbursed if the borrower
subsequently defaults and such capitalized interest is not paid by the
Guarantor.

      Anything in this Section 6 to the contrary notwithstanding, if as of the
last Business Day of any month the aggregate outstanding principal amount of
Trust Student Loans with respect to which claims have been filed with and
rejected by a Guarantor or with respect to which the Servicer determines that
claims cannot be filed pursuant to the Higher Education Act as a result of a
breach by the Seller or the Servicer, exceeds 1% of the Pool Balance, the Seller
or the Servicer shall purchase, within 30 days of a written request of the
Eligible Lender Trustee or the Indenture Trustee, such affected Trust Student
Loans in an aggregate principal amount such that after such purchase the
aggregate principal amount of such affected Trust Student Loans is less than 1%
of the Pool Balance. The Trust Student Loans to be purchased by the Seller or
the Servicer pursuant to the preceding sentence shall be based on the date of
claim rejection (or the date of notice referred to in the first sentence of this
Section 6), with Trust Student Loans with the earliest such date to be purchased
first.

      In lieu of repurchasing Trust Student Loans pursuant to this Section 6,
the Seller may, at its option, substitute Eligible Loans or arrange for the
substitution of Eligible Loans which are


                                       12
<PAGE>

substantially similar on an aggregate basis as of the date of substitution to
the Trust Student Loans for which they are being substituted with respect to the
following characteristics:

            (1)   status (i.e., in-school, grace, deferment, forbearance or
                  repayment),

            (2)   program type (i.e., Unsubsidized Stafford, Subsidized
                  Stafford, Consolidation (pre-1993 vs. post-1993), PLUS or
                  SLS),

            (3)   school type,

            (4)   total return,

            (5)   principal balance, and

            (6)   remaining term to maturity.

      In addition, each substituted Eligible Loan will comply, as of the date of
substitution, with all of the representations and warranties made hereunder. In
choosing Eligible Loans to be substituted pursuant to this Section 6, the Seller
shall make a reasonable determination that the Eligible Loans to be substituted
will not have a material adverse effect on the Noteholders and the
Certificateholders.

      In the event that Seller elects to substitute Eligible Loans pursuant to
this Section 6, the Seller will remit to the Administrator the amount of any
shortfall between the Purchase Amount of the substituted Eligible Loans and the
Purchase Amount of the Trust Student Loans for which they are being substituted.
The Seller shall also remit to the Administrator an amount equal to all
nonguaranteed interest amounts and forfeited Interest Subsidy Payments and
Special Allowance Payments with respect to the Trust Student Loans in the manner
provided in Section 2.6 of the Administration Agreement. The sole remedy of the
Purchaser, the Eligible Lender Trustee, the Certificateholders and the
Noteholders with respect to a breach by the Seller pursuant to Section 5 hereof
shall be to require the Seller to purchase Trust Student Loans, to reimburse the
Purchaser as provided above or to substitute Student Loans pursuant to this
Section. The Eligible Lender Trustee shall have no duty to conduct any
affirmative investigation as to the occurrence of any condition requiring the
purchase of any Trust Student Loan or the reimbursement for any interest penalty
pursuant to this Section 6.

SECTION 7. OBLIGATION TO REMIT SUBSEQUENT PAYMENTS AND FORWARD COMMUNICATIONS

      (A) Any payment received by Seller with respect to amounts accrued after
      the Date of the Bill of Sale for any Loan sold to Purchaser, which payment
      is not reflected in the Loan Transmittal Summary Form, shall be received
      by Seller in trust for the account of Purchaser and the Seller hereby
      disclaims


                                       13
<PAGE>

      any title to or interest in any such amounts. Within two (2) business days
      following the date of receipt, Seller shall remit to Purchaser an amount
      equal to any such payments along with a listing on a form provided by
      Purchaser identifying the Loans with respect to which such payments were
      made, the amount of each such payment and the date each such payment was
      received.

      (B) Any written communication received at any time by Seller with respect
      to any Loan subject to any Sale Agreement shall be transmitted by Seller
      to Servicer within two (2) business days of receipt. Such communications
      shall include, but not be limited to, letters, notices of death or
      disability, notices of bankruptcy, forms requesting deferment of repayment
      or loan cancellation, and like documents.

SECTION 8. CONTINUING OBLIGATION OF SELLER

      Seller shall provide all reasonable assistance necessary for Purchaser to
resolve account problems raised by any Borrower, the Guarantor or the Secretary
provided such account problems are attributable to or are alleged to be
attributable to (a) an event occurring during the period Seller owned the Loan,
or (b) a payment made or alleged to have been made to Seller. Further, the
Seller agrees to execute any financing statements at the request of the
Purchaser in order to reflect the Purchaser's interest in the Loans.

SECTION 9. LIABILITY OF SELLER; INDEMNITIES

      The Seller shall be liable in accordance herewith only to the extent of
the obligations specifically undertaken by the Seller under this Sale Agreement.

      (i) The Seller shall indemnify, defend and hold harmless the Purchaser and
      the Eligible Lender Trustee in its individual capacity and their officers,
      directors, employees and agents from and against any taxes that may at any
      time be asserted against any such Person with respect to the transactions
      contemplated herein and in the other Basic Documents (except any such
      income taxes arising out of fees paid to the Eligible Lender Trustee),
      including any sales, gross receipts, general corporation, tangible and

      intangible personal property, privilege or license taxes and costs and
      expenses in defending against the same.

      (ii) The Seller shall indemnify, defend and hold harmless the Purchaser
      and the Eligible Lender Trustee in its individual capacity and their
      officers, directors, employees and agents of the Purchaser and the
      Eligible Lender Trustee from and against any and all costs, expenses,
      losses, claims, damages and liabilities arising out of, or imposed upon
      such Person through, the Seller's willful misfeasance, bad faith or gross


                                       14
<PAGE>

      negligence in the performance of its duties under the Sale Agreement, or

      Sale Agreement.

      (iii) The Seller shall be liable as primary obligor for, and shall
      indemnify, defend and hold harmless the Eligible Lender Trustee in its
      individual capacity and its officers, directors, employees and agents from

      of the trusts and duties set forth herein and in the Sale Agreement or the
      action or the inaction of the Eligible Lender Trustee hereunder, except to
      the extent that such cost, expense, loss, claim, damage, obligation or
      liability: (a) shall be due to the willful misfeasance, bad faith or
      negligence (except for errors in judgment) of the Eligible Lender Trustee,
      (b) shall arise from any breach by the Eligible Lender Trustee of its
      covenants in its individual capacity under any of the Basic Documents; or
      (c) shall arise from the breach by the Eligible Lender Trustee of any of

      paragraph, the Eligible Lender Trustee's choice of legal counsel shall be
      subject to the approval of the Seller, which approval shall not be
      unreasonably withheld.

      Indemnification under this Section shall survive the resignation or
removal of the Eligible Lender Trustee and the termination of these Master Sale
Terms and shall include reasonable fees and expenses of counsel and expenses of
litigation. If the Seller shall have made any indemnity payments pursuant to
this Section and the Person to or for the benefit of whom such payments are made
thereafter shall collect any of such amounts from others, such Person shall
promptly repay such amounts to the Seller, without interest.

            SELLER

      Any Person (a) into which the Seller may be merged or consolidated, (b)
which may result from any merger or consolidation to which the Seller shall be a
party or (c) which may succeed to the properties and assets of the Seller
substantially as a whole, shall be the successor to the Seller without the
execution or filing of any document or any further act by any of the parties to
these Master Sale Terms; provided, however, that the Seller hereby covenants
that it will not consummate any of the foregoing transactions except upon
satisfaction of the following: (i) the surviving Person, if other than the
Seller, executes an agreement of assumption to perform every obligation of the
Seller under these Master Sale Terms, (ii) immediately after giving effect to
such


                                       15

transaction, no representation or warranty made pursuant to Section 5 herein
shall have been breached, (iii) the surviving Person, if other than the Seller,
shall have delivered to the Eligible Lender Trustee an Officers' Certificate and
an Opinion of Counsel each stating that such consolidation, merger or succession

Opinion of Counsel either (A) stating that, in the opinion of such counsel, all

interest of the Purchaser and the Eligible Lender Trustee, respectively, in the
Loans and reciting the details of such filings, or (B) stating that, in the
opinion of such counsel, no such action shall be necessary to preserve and
protect such interests.

SECTION 11. LIMITATION ON LIABILITY OF SELLER AND OTHERS

      The Seller and any director or officer or employee or agent thereof may
rely in good faith on the advice of counsel or on any document of any kind,
prima facie properly executed and submitted by any Person respecting any matters
arising hereunder (provided that such reliance shall not limit in any way the
Seller's obligations under Section 5 herein). The Seller shall not be under any
obligation to appear in, prosecute or defend any legal action that shall not be
incidental to its obligations under these Master Sale Terms or any Sale
Agreement, and that in its opinion may involve it in any expense or liability.
Except as provided herein, the repurchase (or substitution) and reimbursement
obligations of Seller will constitute the sole remedy available to Purchaser for
uncured breaches; provided, however, that the information with respect to the
Loans listed on the Bill of Sale may be adjusted in the ordinary course of
business subsequent to the date of the Bill of Sale and to the extent that the
aggregate Principal Balance listed on the Bill of Sale is less than the
aggregate Principal Balance stated on the Bill of Sale, Seller shall remit such
amount to the Eligible Lender Trustee for the benefit of the Purchaser. Such
reconciliation payment shall be made from time to time but no less frequently
than semi-annually.

SECTION 12. LIMITATION OF LIABILITY OF ELIGIBLE LENDER TRUSTEE


                                       16
<PAGE>

       Notwithstanding anything contained herein to the contrary, these Master
Sale Terms and any Sale Agreement have been signed by Chase Manhattan Bank
Delaware not in its individual capacity but solely in its capacity as Eligible
Lender Trustee for the Purchaser and the Interim Eligible Lender Trustee for the
Seller, as the case may be, and in no event shall Chase Manhattan Bank Delaware
in its individual capacity, have any liability for the representations,
warranties, covenants, agreements or other obligations of the Eligible Lender
Trustee, the Interim Eligible Lender Trustee, the Purchaser or of the Seller,
respectively, under these Master Sale Terms or any Sale Agreement or in any of
the certificates, notices or agreements delivered pursuant hereto, as to all of
which recourse shall be had solely to the assets of the Purchaser or the Seller,
as the case may be.

SECTION 13. EXPENSES

      Except as otherwise provided herein, each party to these Master Sale Terms
or any Sale Agreement shall pay its own expense incurred in connection with the
preparation, execution and delivery of these Master Sale Terms or any Sale
Agreement and the transactions contemplated herein or therein.

SECTION 14. SURVIVAL OF COVENANTS/SUPERSESSION

      All covenants, agreements, representations and warranties made herein and
in or pursuant to any Sale Agreements executed pursuant to these Master Sale
Terms shall survive the consummation of the purchase of the Loans provided for
in each Sale Agreement. All covenants, agreements, representations and
warranties made or furnished pursuant hereto by or for the benefit of Seller
shall bind and inure to the benefit of any successors or assigns of Purchaser
and shall survive with respect to each Loan. Each Sale Agreement supersedes all
previous agreements and understandings between Purchaser and Seller with respect
to the subject matter thereof. A Sale Agreement may be changed, modified or
discharged, and any rights or obligations hereunder may be waived, only by a
written instrument signed by a duly authorized officer of the party against whom
enforcement of any such waiver, change, modification or discharge is sought. The
waiver by Purchaser of any covenant, agreement, representation or warranty
required to be made or furnished by Seller or the waiver by Purchaser of any
provision herein contained or contained in any Sale Agreement shall not be
deemed to be a waiver of any breach of any other covenant, agreement,
representation, warranty or provision herein contained or contained in any Sale
Agreement, nor shall any waiver or any custom or practice which may evolve
between the parties in the administration of the terms hereof or of any Sale
Agreement, be construed to lessen the right of Purchaser to insist upon the
performance by Seller in strict accordance with said terms.

addressed as set forth in the Sale Agreement or at such other address as either
party may hereafter designate by notice to the other party. Notice given in any
such communication, mailed to Seller or Purchaser by appropriately addressed
registered mail, shall be deemed to have been given on the day following the
date of such mailing.

SECTION 16. FORM OF INSTRUMENTS

Sale Terms and any Sale Agreement, and all proceedings to be taken in connection

proposed amendment or consent, but it shall be sufficient if such consent shall
approve the substance thereof.

      Prior to the execution of any amendment to these Master Sale Terms, the
Eligible Lender Trustee shall be entitled to receive and rely upon an Opinion of
Counsel stating that execution of such amendment is authorized or permitted by
this Sale Agreement and the Opinion of Counsel referred to in Section 7.1 I((i)

            Specified Reserve Account Balance;

            of Available Funds remaining after the application of clauses 1
            through 9, the aggregate unpaid amount of any Swap Payments, if any;

balance of the Reserve Account on such Distribution Date following such
distributions minus (iv) the Specified Reserve Account Balance for that
Distribution Date, or (b) an Insolvency Event with respect to the Seller or an
Event of Default has occurred and is continuing, then, until the conditions

            distributed to the Servicer pursuant to Sections 2.7B and 2.7C.1 on
            such Monthly Servicing Payment Date or Distribution Date, the
            Administrator shall instruct the Indenture Trustee in writing to

<PAGE>

            withdraw from the Reserve Account on such Monthly Servicing Payment
            Date or Distribution Date an amount equal to such excess, to the
            extent of funds available therein, and to distribute such amount to
            the Servicer; provided, however, that, except as provided in
            Sections 2.8C(C) and 2.8D, amounts on deposit in the Reserve Account
            will not be available to cover any unpaid Carryover Servicing Fees
            to the Servicer.

      2.    In the event that the Administration Fee for any Distribution Date
            exceeds the amount distributed to the Administrator pursuant to
            Section 2.7C.2 on such Distribution Date, the Administrator shall
            instruct the Indenture Trustee in writing to withdraw from the
            Reserve Account on each Distribution Date an amount equal to such
            excess, to the extent of funds available therein after giving effect
            to paragraph B.1 above, and to distribute such amount to the
            Administrator.

      3.    In the event that the Swap Fees for any Distribution Date exceed the
            amount distributed to the Swap Counterparties pursuant to Section
            2.7C.3 on such Distribution Date, the Administrator shall instruct
            the Indenture Trustee in writing to withdraw from the Reserve
            Account on each Distribution Date an amount equal to such excess, to
            the extent of funds available therein after giving effect to
            paragraphs B.1 and B.2 above, and to distribute such amount pro rata
            (in proportion to their respective entitlements under the Swap
            Agreements) to the Swap Counterparties.

      4.    In the event that the Noteholders' Interest Distribution Amount and
            the Certificateholders' Interest Distribution Amount for a
            Distribution Date exceeds the amount distributed to the Noteholders
            and to the Certificateholders pursuant to Section 2.7C.4 and C.5 on
            such Distribution Date, the Administrator shall instruct the
            Indenture Trustee in writing to withdraw from the Reserve Account on
            such Distribution Date an amount equal to such excess, to the extent
            of funds available therein after giving effect to paragraphs B.1
            through B.3 above, and to distribute such amount to the Noteholders
            and to the Certificateholders entitled thereto, in the same order
            and priority as is set forth in Sections 2.7C.4 and C.5 subject to
            the last paragraph of Section 2.7C.

      5.    In the event that the Noteholders' Principal Distribution Amount on
            the Final Distribution Date with respect to each Class of Notes
            exceeds the amount distributed to such Noteholders pursuant to
            Section


                                       6
<PAGE>

            2.7C.6 and 2.7C.7 on such Distribution Date, the Administrator shall
            instruct the Indenture Trustee in writing to withdraw from the
            Reserve Account on such final Distribution Date an amount equal to
            such excess, to the extent of funds available therein after giving
            effect to paragraphs B.1 through B.4 above, and to distribute such
            amount to the Noteholders entitled thereto, in the same order and
            priority as is set forth in Sections 2.7C.6 and 2.7C.7.

      6.    In the event that the Certificateholders' Principal Distribution
            Amount on the final Distribution Date with respect to the
            Certificates exceeds the amount distributed to the
            Certificateholders pursuant to Section 2.7C.8 on such Distribution
            Date, the Administrator shall instruct the Indenture Trustee in
            writing to withdraw from the Reserve Account on such Distribution
            Date an amount equal to such excess, to the extent of funds
            available therein after giving effect to paragraphs B.1 through B.5
            above, and to distribute such amount to the Eligible Lender Trustee
            on behalf of the Certificateholders, for distribution to the
            Certificateholders entitled thereto.

      C.1. After giving effect to Section 2.8B, if the amount on deposit in the
Reserve Account on any Distribution Date (after giving effect to all deposits or
withdrawals therefrom on such Distribution Date other than pursuant to this
paragraph C.1) is greater than the Specified Reserve Account Balance for such
Distribution Date, the Administrator shall instruct the Indenture Trustee in
writing (A) to pay to the Noteholders out of such excess in the Reserve Account
an amount equal to the Note Principal Shortfall, if any; (B) to pay to the
Certificateholders out of such excess in the Reserve Account an amount equal to
the Certificate Principal Shortfall, if any; (C) to pay the Swap Counterparties,
pro rata (in proportion to their respective entitlements under the Swap
Agreements), out of such excess in the Reserve Account an amount equal to the
amount described in Section 2.7C.10 for such Distribution Date (to the extent
not otherwise paid to the Swap Counterparties on such Distribution Date); (D) to
pay to the Servicer out of such excess in the Reserve Account an amount equal to
the amount described in Section 2.7C.11 for such Distribution Date (to the
extent not otherwise paid to the Servicer on such Distribution Date); (E) in the
event the Trust Student Loans are not sold pursuant to Section 6.1A, to pay as
an accelerated payment of principal balance of the Notes or Certificate Balance,
as the case may be, first to the Noteholders in the same order and priority as
is set forth in Sections 2.7C.6 and C.7 until the principal amount of the Notes
is paid in full and then to the Certificateholders until the Certificate
Principal Balance is reduced to zero, provided that the amount of such
distribution shall not exceed


                                       7
<PAGE>

the outstanding principal balance of the Notes or the Certificates, as
applicable, after giving effect to all other payments in respect of principal of
Notes and Certificates to be made on such date; and (F) to distribute the
remaining amount of such excess (i) to the Seller, to the extent of any portion
thereof that is attributable to the reduction from time to time of the Specified
Reserve Account Balance, and (ii) to the Seller or its assignee, as holder of
the Excess Distribution Certificate, any remaining portion thereof. Amounts
properly distributed to the Seller or such holder pursuant to this paragraph C.1
shall be deemed released from the Trust Estate and the security interest therein
granted to the Indenture Trustee, and the Seller or such holder shall in no
event thereafter be required to refund any such distributed amounts.

      C.2. In the event of a termination of a Swap Agreement that requires the
Trust to make a termination payment to the applicable Swap Counterparty, such
termination payment shall be paid in the same order of priority as the Swap Fee
in Sections 2.7C.3 and 2.8B.3 and the Swap Payment in Sections 2.7C.10 and
2.8C.1(C), as the case may be; provided, however, that in the event that the
Trust is required to make a termination payment to a Swap Counterparty as a
result of (i) an Event of Default (as such term is defined in the Swap
Agreement) where the Swap Counterparty is the Defaulting Party (as such term is
defined in the Swap Agreement) or (ii) a Termination Event (as such term is
defined in the Swap Agreement), such termination payment will be subordinate in
priority to the right of the Noteholders to receive the Noteholders'
Distribution Amount and to the Certificateholders to receive the
Certificateholders' Distribution Amount and, if necessary, to the reinstatement
of the balance of the Reserve Account up to the Specified Reserve Account
Balance. In the event of a termination of a Swap Agreement that requires the
Trust to make a termination payment to the applicable Swap Counterparty except
as described in the proviso above, the Administrator promptly shall notify the
Rating Agencies of such requirement and, within thirty (30) days of such
termination payment, shall provide to the Rating Agencies cash flows and such
other financial information with respect to the Trust as the Rating Agencies may
reasonably request.

      D. On the final Distribution Date upon termination of the Trust and
following the payment in full of the aggregate outstanding principal balance of
the Notes and the Certificate Principal Balance and of all other amounts (other
than Swap Payments and Carryover Servicing Fees) owing or to be distributed
hereunder or under the Indenture or the Trust Agreement to Noteholders,
Certificateholders, the Servicer, the Administrator or the Swap Counterparties,
to the extent that Available Funds on such date are insufficient to make the
following payments, amounts remaining in the Reserve Account shall be used first
to pay any unpaid Swap Payments and second to pay any Carryover


                                       8
<PAGE>

Servicing Fees. Any amount remaining on deposit in the Reserve Account after
such payments have been made shall be distributed to the Seller. The Seller
shall in no event be required to refund any amounts properly distributed
pursuant to this Section 2.8D.

      E. Anything in this Section 2.8 to the contrary notwithstanding, if the
market value of securities and cash in the Reserve Account is on any
Distribution Date sufficient to pay the remaining principal amount of and
interest accrued on the Notes, to reduce the Certificate Principal Balance to
zero and to pay any accrued return thereon and to pay any unpaid Swap Payments
and Carryover Servicing Fee, such amount will be so applied on such Distribution
Date and the Administrator shall instruct the Eligible Lender Trustee and the
Indenture Trustee to make such payments.

      (d) Section 2.9.e is deleted, Sections 2.9.f-j are redesignated as
Sections 2.9.e-i and the following is inserted as Section 2.9.j:

            j. The amount of the Swap Fee and Swap Payments made to the Swap
            Counterparties on such Distribution Date;

In addition, the first sentence of the first paragraph after Section 2.9.n is
deleted and replaced with the following:

      Each amount set forth pursuant to clauses (a), (b), (c), (d), (h), (i) and
(l) above shall be expressed as a dollar amount per $1,000 of original principal
balance of a Note or Certificate, as applicable.

      (e) The last sentence of Section 3.1D is deleted and replaced with the
following:

      In connection therewith, the Administrator shall calculate the T-Bill Rate
and Three-Month LIBOR or Six-Month LIBOR, as applicable, in accordance with the
definitions thereof and shall also determine the Student Loan Rate with respect
to such Distribution Date. In addition, the Administrator hereby accepts the
delegation to it of the obligations of the "Calculation Agent" under the Swap
Agreements.

      (f) A new subparagraph, 4.2 (iv), is inserted as follows:

      and
      (iv) any claim for failure to comply with the provisions of 34 CFR Sec.
      682.203(b) (other than for the Eligible Lender Trustee's failure to
      qualify as an eligible lender under the Act).


                                       9
<PAGE>

In addition, the "or" is deleted from subparagraph 4.2 (ii) and the "." is
deleted from subparagraph 4.2 (iii) and is replaced ";".

      (g) Sections 6.1A and B are deleted and replaced with the following:
Section 6.1  Termination.

      A. Optional Purchase of All Trust Student Loans. The Administrator shall
notify the Seller and the Indenture Trustee in writing, within 15 days after the
last day of any Collection Period as of which the then outstanding Pool Balance
is 12% or less of the Initial Pool Balance, of the percentage that the then
outstanding Pool Balance bears to the Initial Pool Balance. As of the last day
of any Collection Period immediately preceding a Distribution Date as of which
the then outstanding Pool Balance is 10% or less of the Initial Pool Balance,
the Eligible Lender Trustee on behalf and at the direction of the Seller, or any
other "eligible lender" (within the meaning of the Higher Education Act)
designated by the Seller in writing to the Eligible Lender Trustee and the
Indenture Trustee, shall have the option to purchase the Trust Estate, other
than the Trust Accounts. To exercise such option, the Seller shall deposit
pursuant to Section 2.6 in the Collection Account an amount equal to the
aggregate Purchase Amount for the Trust Student Loans and the related rights
with respect thereto, plus the appraised value of any such other property held
by the Trust other than the Trust Accounts, such value to be determined by an
appraiser mutually agreed upon by the Seller, the Eligible Lender Trustee and
the Indenture Trustee, and shall succeed to all interests in and to the Trust;
provided, however, that the Seller may not effect such purchase if such
aggregate Purchase Amounts do not equal or exceed the Minimum Purchase Amount
plus any amounts owing to the Swap Counterparties and any Carryover Servicing
Fees. In the event the Seller fails to notify the Eligible Lender Trustee and
the Indenture Trustee in writing prior to the acceptance by the Indenture
Trustee of a bid to purchase the Trust Estate pursuant to Section 4.4 of the
Indenture that the Seller intends to exercise its option to purchase the Trust
Estate, the Seller shall be deemed to have waived its option to purchase the
Trust Estate as long as the Seller has received 5 business days' notice from the
Indenture Trustee as provided in Section 4.4 of the Indenture.

      B. Insolvency of the Seller. Upon any sale of the assets of the Trust
pursuant to Section 9.2 of the Trust Agreement, the Administrator shall instruct
the Indenture Trustee in writing to deposit the net proceeds from such sale
after all payments and reserves therefrom (including the expenses of such sale)
have been made (the "Insolvency Proceeds") in the Collection Account. On the
first Distribution Date following the date on which the Insolvency Proceeds are
deposited in the Collection Account, the


                                       10
<PAGE>

Administrator shall instruct the Indenture Trustee to make the following
distributions (after the application on such Distribution Date of the amount of
Available Funds and amounts on deposit in the Reserve Account pursuant to
Sections 2.7 and 2.8) from the Insolvency Proceeds and any funds remaining on
deposit in the Reserve Account (including the proceeds of any sale of
investments therein as described in the following sentence):

      a.    to the Noteholders, any unpaid Noteholders' Interest Distribution
            Amount for such Distribution Date as set forth in Sections 2.7C.4;

      b.    to the Noteholders, the outstanding principal balance of the Notes
            in the same order and priority as is set forth in Sections 2.7C.6
            and C.7;

      c.    to the Certificateholders, any unpaid Certificate Interest
            Distribution Amount for such Distribution Date;

      d.    to the Certificateholders, the Certificate Principal Balance;

      e.    to the Swap Counterparties, pro rata (in proportion to their
            respective entitlements under the Swap Agreements), any unpaid Swap
            Payments; and

      f.    to the Servicer, any unpaid Carryover Servicing Fees.

      Any investment on deposit in the Reserve Account that will not mature on
      or before such Distribution Date shall be sold by the Indenture Trustee at
      such time as will result in the Indenture Trustee receiving the proceeds
      from such sale not later than the Business Day preceding such Distribution
      Date. Any Insolvency Proceeds remaining after the deposits described above
      shall be paid to the Seller.

      (h) Section 8.5 is amended by inserting at the end of the first paragraph
the following:

      and that such action will not materially adversely affect (i) the Trust's
      ability to enforce or protect its rights or remedies under the Swap
      Agreements, (ii) the ability of the Trust to timely and fully perform its
      obligations under the Swap Agreements or (iii) any of the Trust's
      obligations under the Swap Agreements or any swap transaction under such
      agreements. Any such amendment, modification or supplement without the
      applicable Swap Counterparty's consent shall not be binding on that Swap
      Counterparty.

6. Each of the parties named on the signature pages to this Supplement by
execution of this Supplement agrees, for the


                                       11

benefit of the Administrator and the other signatories hereto, to be bound by
the terms of the Agreement in connection with the Trust, this Supplement and the
other Basic Documents to the extent reference is made in the Agreement to such
party. The rights and obligations of such parties under the Agreement resulting
from the execution of this Supplement (other than the Seller) shall be
applicable only with respect to the Trust, this Supplement and the other Basic
Documents.

      This Supplement shall be construed in accordance with the laws of the
State of New York, without reference to the conflict of law provisions thereof,
and the obligations, rights and remedies of the parties hereunder shall be
determined in accordance with such laws.

      This Supplement may be executed in counterparts, each of which when so
executed shall together constitute but one and the same instrument. IN WITNESS
WHEREOF, the parties hereto have caused this Supplement to be duly executed and
delivered as of the date first above written.

                              SERVICING AGREEMENT

               Sallie Mae Servicing Corporation ("Servicer"), a corporation
organized under the laws of the State of Delaware, hereby agrees with SLM
Student Loan Trust 2000-3 (the "Issuer"), Chase Manhattan Bank Delaware, not in
its individual capacity but in its capacity as trustee under a trust agreement
dated April 1, 2000 between SLM Funding Corporation and Chase Manhattan Bank
Delaware ("Eligible Lender Trustee"), the Student Loan Marketing Association, a
federally chartered corporation ("Administrator") and Bankers Trust Company, a
New York banking corporation, not in its individual capacity but in its capacity
as Indenture Trustee under an Indenture dated April 1, 2000 between SLM Student
Loan Trust 2000-3 and Bankers Trust Company (the "Indenture Trustee"), as
follows:

               WHEREAS, Eligible Lender Trustee will acquire certain education
loans to be held in the Trust formed pursuant to a trust agreement (the "Trust
Agreement"), dated as of April 1, 2000, between SLM Funding Corporation and
Eligible Lender Trustee;

               WHEREAS, the Issuer will issue notes (the "Notes") pursuant to an
indenture (the "Indenture"), dated as of April 1, 2000, between the Issuer and
the Indenture Trustee and trust certificates (the "Certificates") pursuant to
the Trust Agreement, which Notes and Certificates are payable from the assets of
the Issuer;

               WHEREAS, the Issuer, the Administrator and the Eligible Lender
Trustee desire Servicer to service said education loans held by the Eligible
Lender Trustee on behalf of the Issuer, and Servicer is willing to service said
education loans for the Issuer, the Administrator, the Eligible Lender Trustee
and the Indenture Trustee;

               NOW, THEREFORE, in consideration of the premises and mutual
covenants herein contained, the parties hereto agree as follows:

                                    Article I

Section 1.1 Definitions and Usage. Except as otherwise specified herein or as
the context may otherwise require, capitalized terms used but not otherwise
defined herein are defined in Appendix A hereto, which also contains rules as to
usage that shall be applicable herein.

                                   Article II

Section 2.1 Custody of Trust Student Loan Files. To assure uniform quality in
servicing the Trust Student Loans and to reduce administrative costs, the Issuer
hereby revocably appoints
<PAGE>

the Servicer, and the Servicer hereby accepts such appointment, to act for the
benefit of the Issuer and the Indenture Trustee as custodian of the following
documents or instruments (collectively the "Trust Student Loan Files") which are
hereby constructively delivered to the Indenture Trustee, as pledgee of the
Issuer with respect to each Trust Student Loan:

      (a)   the original fully executed copy of the note evidencing the Trust
            Student Loan; and

      (b)   any and all other documents and computerized records that the
            Servicer shall keep on file, in accordance with its customary
            procedures, relating to such Trust Student Loan or any obligor with
            respect thereto.

Section 2.2 Duties of Servicer as Custodian. The Servicer shall hold the Trust
Student Loan Files for the benefit of the Issuer and the Indenture Trustee and
maintain such accurate and complete accounts, records and computer systems
pertaining to each Trust Student Loan File as shall enable the Issuer to comply
with this Agreement. In performing its duties as custodian the Servicer shall
act with reasonable care, using that degree of skill and attention that the
Servicer exercises with respect to the student loan files relating to comparable
student loans that the Servicer services on behalf of the Student Loan Marketing
Association and shall ensure that it fully complies with all applicable Federal
and state laws, including the Higher Education Act, with respect thereto. The
Servicer shall take all actions necessary with respect to the Trust Student Loan
Files held by it under this Agreement and of the related accounts, records and
computer systems, in order to enable the Issuer or the Indenture Trustee to
verify the accuracy of the Servicer's record keeping with respect to the
Servicer's obligations as custodian hereunder. The Servicer shall promptly
report to the Issuer, the Administrator and the Indenture Trustee any material
failure on its part to hold the Trust Student Loan Files and maintain its
accounts, records and computer systems as herein provided and promptly take
appropriate action to remedy any such failure. Nothing herein shall be deemed to
require an initial review or any periodic review by the Issuer, the Eligible
Lender Trustee or the Indenture Trustee of the Trust Student Loan Files. If in
the reasonable judgment of the Eligible Lender Trustee it is necessary to
preserve the interests of the Noteholders, Certificateholders and the Trust in
the Trust Student Loans or at the request of the Administrator, the Servicer
shall transfer physical possession of the notes evidencing the Trust Student
Loans to the Eligible Lender Trustee, the Indenture Trustee or any other
custodian for either of them designated by the Eligible Lender Trustee.


                                       2

Section 2.3 Maintenance of and Access to Records. The Servicer shall maintain
each Trust Student Loan File at one of its offices specified in Attachment B to
this Agreement or at such other office as shall be consented to by the Issuer
and the Indenture Trustee upon written notice to the Issuer and the Indenture
Trustee. Upon reasonable prior notice, the Servicer shall make available to the
Issuer and the Indenture Trustee or their respective duly authorized
representatives, attorneys or auditors a list of locations of the Trust Student
Loan Files and the related accounts, records and computer systems maintained by
the Servicer at such times during normal business hours as the Issuer or the
Indenture Trustee shall instruct.

Section 2.4 Release of Documents. Upon written instruction from the Indenture
Trustee, the Servicer shall release any Trust Student Loan File to the Indenture
Trustee, the Indenture Trustee's agent, or the Indenture Trustee's designee, as
the case may be, at such place or places as the Indenture Trustee may reasonably
designate, as soon as practicable. The Indenture Trustee shall cooperate with
the Servicer to provide the Servicer with access to the Trust Student Loan Files
in order for the Servicer to continue to service the Trust Student Loans after
the release of the Trust Student Loan Files. In the event the Servicer is not
provided access to the Trust Student Loan Files, the Servicer shall not be
deemed to have breached its obligations pursuant to Section 3.1, 3.2, 3.3 or 3.4
if it is unable to perform such obligations due to its inability to have access
to the Trust Student Loans Files. The Servicer shall not be liable for any
losses with respect to the servicing of such Trust Student Loans arising after
the release of the related Trust Student Loan Files to the extent the losses are
attributable to the Servicer's inability to have access to the related Trust
Student Loan Files.

Section 2.5 Instructions; Authority To Act. The Servicer shall be deemed to have
received proper instructions with respect to the Trust Student Loan Files upon
its receipt of written instructions signed by a Responsible Officer of the
Indenture Trustee.

Section 2.6  [RESERVED].

Section 2.7 Effective Period and Termination. Sallie Mae Servicing Corporation's
appointment as custodian shall become effective as of the Closing Date and shall
continue in full force and effect for so long as Sallie Mae Servicing
Corporation shall remain the Servicer hereunder. If Sallie Mae Servicing
Corporation or any successor Servicer shall resign as Servicer in


                                       3
<PAGE>

accordance with the provisions of this Agreement or if all the rights and
obligations of Sallie Mae Servicing Corporation or any such successor Servicer
shall have been terminated under Section 5.1, the appointment of Sallie Mae
Servicing Corporation or such successor Servicer as custodian shall be
terminated simultaneously with the effectiveness of such resignation or
termination. On or prior to the effective date of any resignation or termination
of such appointment, the Servicer shall deliver the Trust Student Loan Files to
the successor Servicer, the Indenture Trustee or the Indenture Trustee's agent,
at the direction of the Indenture Trustee, at such place or places as the
Indenture Trustee may reasonably designate. In establishing an effective date
for the termination of the Servicer as custodian of the Trust Student Loan
Files, the parties shall provide for a reasonable period for the Servicer to
deliver the Trust Student Loan Files to its designated successor.

                                   Article III

Section 3.1 Duties of Servicer. The Servicer, for the benefit of the Issuer (to
the extent provided herein), shall manage, service, administer and make
collections on the Trust Student Loans with reasonable care, using that degree
of skill and attention that the Servicer exercises with respect to comparable
student loans that it services on behalf of the Student Loan Marketing
Association from the Closing Date (or with respect to Trust Student Loans which
are sold to the Issuer following the Closing Date, such later date as the Trust
Student Loans are delivered to Servicer for servicing hereunder) until the Trust
Student Loans are paid in full. At any time that substantially all remaining
Trust Student Loans are repurchased by SLM Funding Corporation from the Issuer
pursuant to Section 6.1 of the Administration Agreement, the Servicer agrees to
execute, at the request of SLM Funding Corporation, a new servicing agreement
which agreement shall include terms and conditions substantially the same as the
terms and conditions of this Agreement; provided, however, the Servicer shall
not be required to so execute a new servicing agreement until it has received
all Servicing Fees then due and payable hereunder. Without limiting the
generality of the foregoing or of any other provision set forth in this
Agreement and notwithstanding any other provision to the contrary set forth
herein, the Servicer shall manage, service, administer and make collections with
respect to the Trust Student Loans (including collection of any Interest Subsidy
Payments and Special Allowance Payments on behalf of the Eligible Lender
Trustee) in accordance with, and otherwise comply with, all applicable Federal
and state laws, including all applicable rules, regulations and other
requirements of the Higher Education Act and the applicable Guarantee Agreement,
the failure to comply with which would adversely affect the eligibility of one
or more


                                       4
<PAGE>

of the Trust Student Loans for Federal reinsurance or Interest Subsidy Payments
or Special Allowance Payments or one or more of the Trust Student Loans for
receipt of Guarantee Payments.

      The Servicer's duties shall include, but shall not be limited to,
collection and posting of all payments, responding to inquiries of borrowers on
such Trust Student Loans, monitoring borrowers' status, making required
disclosures to borrowers, performing due diligence with respect to borrower
delinquencies, sending payment coupons to borrowers and otherwise establishing
repayment terms, reporting tax information to borrowers, if applicable,
accounting for collections and furnishing monthly statements with respect
thereto to the Administrator. The Servicer shall follow its customary standards,
policies and procedures in performing its duties as Servicer. Without limiting
the generality of the foregoing, the Servicer is authorized and empowered to
execute and deliver, on behalf of itself, the Issuer, the Eligible Lender
Trustee, the Indenture Trustee, the Certificateholders and the Noteholders or
any of them, instruments of satisfaction or cancellation, or partial or full
release or discharge, and all other comparable instruments, with respect to such
Trust Student Loans; provided, however, that the Servicer agrees that it will
not (a) permit any rescission or cancellation of a Trust Student Loan except as
ordered by a court of competent jurisdiction or governmental authority or as
otherwise consented to in writing by the Eligible Lender Trustee and the
Indenture Trustee provided, however, that the Servicer may write off any
delinquent Trust Student Loan if the remaining balance of the borrower's account
is less than $50 or (b) reschedule, revise, defer or otherwise compromise with
respect to payments due on any Trust Student Loan except pursuant to any
applicable interest only, deferral or forbearance periods or otherwise in
accordance with all applicable standards, guidelines and requirements with
respect to the servicing of Student Loans; provided further, however, that the
Servicer shall not agree to any reduction of yield with respect to any Trust
Student Loan (either by reducing borrower payments or reducing principal
balance) except as permitted in accordance with Section 3.12 or otherwise if,
and to the extent, the Servicer or the Administrator reimburses the Issuer in an
amount sufficient to offset any such effective yield reduction made by the
Servicer consistent with such customary servicing procedures as it follows with
respect to comparable Student Loans which it services on behalf of the Student
Loan Marketing Association. The Eligible Lender Trustee on behalf of the Issuer
hereby grants a power of attorney and all necessary authorization to the
Servicer to maintain any and all collection procedures with respect to the Trust
Student Loans, including filing, pursuing and recovering claims with the
Guarantors for Guarantee Payments and with the Department for Interest Benefit
Payments and Special Allowance Payments and taking any steps to enforce such
Trust Student Loans


                                       5
<PAGE>

such as commencing a legal proceeding to enforce a Trust Student Loan in the
names of the Issuer, the Eligible Lender Trustee, the Indenture Trustee, the
Certificateholders and the Noteholders. The Eligible Lender Trustee shall upon
the written request of the Servicer furnish the Servicer with any other powers
of attorney and other documents reasonably necessary or appropriate to enable
the Servicer to carry out its servicing and administrative duties hereunder.

Section 3.2 Collection of Trust Student Loan Payments.

      A. The Servicer shall make reasonable efforts (including all efforts that
may be specified under the Higher Education Act or any Guarantee Agreement) to
collect all payments called for under the terms and provisions of the Trust
Student Loans as and when the same shall become due and shall follow such
collection procedures as it follows with respect to comparable student loans
that it services on behalf of the Student Loan Marketing Association. The
Servicer shall allocate collections with respect to the Trust Student Loans
between principal and interest in accordance with Section 2.5 of the
Administration Agreement. The Servicer may in its discretion waive any late
payment charge or any other fees that may be collected in the ordinary course of
servicing a Trust Student Loan. The Servicer may, at its option, retain any late
payment charges which it collects.

      B. The Servicer shall make reasonable efforts to claim, pursue and collect
all Guarantee Payments from the Guarantors pursuant to the Guarantee Agreements
with respect to any of the Trust Student Loans as and when the same shall become
due and payable, shall comply with all applicable laws and agreements with
respect to claiming, pursuing and collecting such payments and shall follow such
practices and procedures as it follows with respect to comparable guarantee
agreements and student loans that it services on behalf of the Student Loan
Marketing Association. In connection therewith, the Servicer is hereby
authorized and empowered to convey to any Guarantor the note and the related
Trust Student Loan File representing any Trust Student Loan in connection with
submitting a claim to such Guarantor for a Guarantee Payment in accordance with
the terms of the applicable Guarantee Agreement. All amounts so collected by the
Servicer shall constitute Available Funds for the applicable Collection Period
and shall be deposited into the Collection Account or transferred to the
Administrator in accordance with Section 2.4 of the Administration Agreement.
The Eligible Lender Trustee shall, upon the written request of the Servicer,
furnish the Servicer with any power of attorney and other documents necessary or
appropriate to enable the Servicer to convey such documents to any Guarantor and
to make such claims.


                                       6
<PAGE>

      C. The Servicer on behalf of the Eligible Lender Trustee shall, on behalf
of the Issuer, make reasonable efforts to claim, pursue and collect all Interest
Subsidy Payments and Special Allowance Payments from the Department with respect
to any of the Trust Student Loans as and when the same shall become due and
payable, shall comply with all applicable laws and agreements with respect to
claiming, pursuing and collecting such payments and shall follow such practices
and procedures as the Servicer follows with respect to comparable student loans
that it services on behalf of the Student Loan Marketing Association. All
amounts so collected by the Servicer shall constitute Available Funds for the
applicable Collection Period and shall be deposited into the Collection Account
or transferred to the Administrator in accordance with Section 2.4 of the
Administration Agreement. In connection therewith, the Servicer shall prepare
and file with the Department on a timely basis all claims forms and other
documents and filings necessary or appropriate in connection with the claiming
of Interest Subsidy Payments and Special Allowance Payments on behalf of the
Eligible Lender Trustee and shall otherwise assist the Eligible Lender Trustee
in pursuing and collecting such Interest Subsidy Payments and Special Allowance
Payments from the Department. The Eligible Lender Trustee shall upon the written
request of the Servicer furnish the Servicer with any power of attorney and
other documents reasonably necessary or appropriate to enable the Servicer to
prepare and file such claims forms and other documents and filings.

Section 3.3 Realization upon Trust Student Loans. For the benefit of the Issuer,
the Servicer shall use reasonable efforts consistent with its servicing
practices and procedures that it utilizes with respect to comparable student
loans that it services on behalf of the Student Loan Marketing Association and
including all efforts that may be specified under the Higher Education Act or
any Guarantee Agreement in its servicing of any delinquent Trust Student Loans.

Section 3.4 No Impairment. The Servicer shall not impair the rights of the
Issuer, the Eligible Lender Trustee, the Indenture Trustee, the
Certificateholders or Noteholders in such Trust Student Loans.

Section 3.5 Purchase of Trust Student Loans; Reimbursement.

      A. The Servicer, the Administrator, the Eligible Lender Trustee and the
Indenture Trustee shall give notice to the other parties promptly, in writing,
upon the discovery of any breach of the provisions of Section 3.1, 3.2, 3.3 or
3.4 which has a materially adverse effect on the interest of the Issuer. In the
event of such a material breach which is not curable by reinstatement of the
Guarantor's guarantee of such Trust Student


                                       7
<PAGE>

Loan, the Servicer shall purchase the affected Trust Student Loan not later than
120 days following the earlier of the date of discovery of such material breach
and the date of receipt of the Guarantor reject transmittal form with respect to
such Trust Student Loan. In the event of a material breach with respect to such
Trust Student Loan which is curable by reinstatement of the Guarantor's
guarantee of such Trust Student Loan, unless the material breach shall have been
cured within 360 days following the earlier of the date of discovery of such
material breach and the date of receipt of the Guarantor reject transmittal form
with respect to such Trust Student Loan, the Servicer shall purchase such Trust
Student Loan not later than the sixtieth day following the end of such 360-day
period. The purchase price hereunder will be the unpaid principal amount of such
Trust Student Loan plus accrued interest (calculated using the applicable
percentage that would have been insured pursuant to Section 428(b)(1)(G) of the
Higher Education Act) plus an amount equal to all forfeited Interest Subsidy
Payments and Special Allowance Payments with respect to such Trust Student Loan.
The Servicer shall remit the purchase price to the Administrator as provided in
Section 2.6 of the Administration Agreement on the date of purchase of any Trust
Student Loan pursuant to this Section 3.5. In consideration of the purchase of
any such Trust Student Loan pursuant to this Section 3.5, the Servicer shall
remit the Purchase Amount in the manner specified in Section 2.6 of the
Administration Agreement. Any breach that relates to compliance with the
requirements of the Higher Education Act or of the applicable Guarantor but that
does not affect such Guarantor's obligation to guarantee payments of a Trust
Student Loan will not be considered to have a material adverse effect for
purposes of this Section 3.5A.

      B. In addition, if any breach of Section 3.1, 3.2, 3.3 or 3.4 by the
Servicer does not trigger such purchase obligation but does result in the
refusal by a Guarantor to guarantee all or a portion of the accrued interest (or
any obligation of the Issuer to repay such interest to a Guarantor), or the loss
(including any obligation of the Issuer to repay to the Department) of Interest
Subsidy Payments and Special Allowance Payments, with respect to any Trust
Student Loan affected by such breach, then the Servicer shall reimburse the
Issuer in an amount equal to the sum of all such nonguaranteed interest amounts
that would have been owed to the Issuer by the Guarantor but for such breach by
the Servicer and such forfeited Interest Subsidy Payments or Special Allowance
Payments by netting such sum against the Servicing Fee payable to the Servicer
for such period and remitting any additional amounts owed in the manner
specified in Section 2.6 of the Administration Agreement not later than (i) the
last day of the next Collection Period ending not less than 60 days from the
date of the Guarantor's refusal to guarantee all or a portion of accrued
interest or loss of Interest Subsidy Payments or Special Allowance Payments, or


                                       8
<PAGE>

(ii) in the case where the Servicer reasonably believes such amounts are likely
to be collected, not later than the last day of the next Collection Period
ending not less than 360 days from the date of the Guarantor's refusal to
guarantee all or a portion of accrued interest or loss of Interest Subsidy
Payments or Special Allowance Payments. At the time such payment is made, the
Servicer shall not be required to reimburse the Issuer for interest that is then
capitalized, however, such amounts shall be reimbursed if the borrower
subsequently defaults and such capitalized interest is not paid by the
Guarantor.

      C. Anything in this Section 3.5 to the contrary notwithstanding, if as of
the last Business Day of any month the aggregate outstanding principal amount of
Trust Student Loans with respect to which claims have been filed with and
rejected by a Guarantor or with respect to which the Servicer determines that
claims cannot be filed pursuant to the Higher Education Act as a result of a
breach by the Servicer or the Seller, exceeds 1% of the Pool Balance, the
Servicer or the Seller, as appropriate, shall purchase, within 30 days of a
written request of the Eligible Lender Trustee or Indenture Trustee, such
affected Trust Student Loans in an aggregate principal amount such that after
such purchase the aggregate principal amount of such affected Trust Student
Loans is less than 1% of the Pool Balance. The Trust Student Loans to be
purchased by the Servicer or the Seller pursuant to the preceding sentence shall
be based on the date of claim rejection (or date of notice referred to in the
first sentence of this Section 3.5) with the Trust Student Loans with the
earliest such date to be purchased first.

      D. In lieu of repurchasing Trust Student Loans pursuant to this Section
3.5, the Servicer may, at its option, with the prior consent of the
Administrator, substitute Student Loans or arrange for the substitution of
Student Loans which are substantially similar as of the date of substitution on
an aggregate basis to the Trust Student Loans for which they are being
substituted with respect to the following characteristics:

      (1)   status (i.e., in-school, grace, deferment, forbearance or
            repayment),

      (2)   program type (i.e., unsubsidized Stafford, subsidized Stafford,
            Consolidation (pre-1993 vs. post-1993) PLUS or SLS),

      (3)   school type,

      (4)   total return,

      (5)   principal balance, and

      (6)   remaining term to maturity.

In addition, each substituted Student Loan shall comply, as of the date of
substitution, with the representations and warranties made by the Seller in the
Sale Agreement. In choosing Student


                                       9
<PAGE>

Loans to be substituted pursuant to this subsection D, the Servicer shall make a
reasonable determination that the Student Loans to be substituted will not have
a material adverse effect on the Noteholders and the Certificateholders.

      In the event the Servicer elects to substitute Student Loans pursuant to
this Section 3.5 and the Administrator consents to such substitution, the
Servicer will remit to the Administrator the amount of any shortfall between the
Purchase Amount of the substituted Student Loans and the Purchase Amount of the
Trust Student Loans for which they are being substituted. The Servicer shall
also remit to the Administrator an amount equal to all nonguaranteed interest
amounts that would have been owed to the Issuer by the Guarantor but for the
breach of the Servicer and forfeited Interest Subsidy Payments and Special
Allowance Payments with respect to the Trust Student Loans in the manner
provided in Section 2.6 of the Administration Agreement.

      E. The sole remedy of the Issuer, the Eligible Lender Trustee, the
Indenture Trustee, the Certificateholders and the Noteholders with respect to a
breach pursuant to Section 3.1, 3.2, 3.3 or 3.4 shall be to require the Servicer
to purchase Trust Student Loans, to reimburse the Issuer as provided above or to
substitute Student Loans pursuant to this Section.

      F. The Eligible Lender Trustee shall have no duty to conduct any
affirmative investigation as to the occurrence of any condition requiring the
purchase of any Trust Student Loan or the reimbursement for any interest penalty
pursuant to this Section 3.5.

      G. The Servicer shall not be deemed to have breached its obligations
pursuant to Section 3.1, 3.2, 3.3 or 3.4 if it is rendered unable to perform
such obligations, in whole or in part, by a force outside the control of the
parties hereto (including acts of God, acts of war, fires, earthquakes,
hurricanes, floods and other disasters). The Servicer shall diligently perform
its duties under this Agreement as soon as practicable following the termination
of such interruption of business.

Section 3.6 Primary Servicing Fee; Carryover Servicing Fee. The Primary
Servicing Fee for each calendar month and any Carryover Servicing Fees payable
on any Distribution Date in arrears by the Issuer shall be equal to the amounts
determined by reference to the schedule of fees attached hereto as Attachment A.
Notwithstanding anything to the contrary contained herein or in any other Basic
Document, the Servicer shall be entitled to receive any Carryover Servicing Fee
on any Distribution Date only


                                       10
<PAGE>

if and to the extent that sufficient funds are available pursuant to Section
2.7.C of the Administration Agreement.

Section 3.7 Access to Certain Documentation and Information Regarding Trust
Student Loans. Upon reasonable prior notice, the Servicer shall provide to the
Administrator and its agents access to the Trust Student Loan Files and shall
permit the Administrator to examine and make copies of, and abstracts from, the
records and books of account of the Servicer relating to the Trust Student Loans
and shall permit the Administrator to undertake periodic site reviews of the
Servicer's operations relating to the servicing of the Trust Student Loans
(including on the premises of any agent of the Servicer). Reasonable access
shall be afforded to the Administrator without charge, but only upon reasonable
request and during the normal business hours at the respective offices of the
Servicer. Nothing in this Section shall affect the obligation of the Servicer to
observe any applicable law prohibiting disclosure of information regarding the
Obligors and the failure of the Servicer to provide access to information as a
result of such obligation shall not constitute a breach of this Section.

Section 3.8 Servicer Expenses. The Servicer shall be required to pay all
expenses incurred by it in connection with its activities hereunder, including
fees and disbursements of independent accountants, taxes imposed on the Servicer
and expenses incurred in connection with distributions and reports to the
Administrator provided, however, the Carryover Servicing Fee will be subject to
increase agreed to by the Administrator, the Eligible Lender Trustee and the
Servicer to the extent that a demonstrable and significant increase occurs in
the costs incurred by the Servicer in providing the services to be provided
hereunder, whether due to changes in applicable governmental regulations,
Guarantor program requirements or regulations or postal rates. Notwithstanding
anything to the contrary contained herein, the Servicer may, at its option,
collect fees from the Borrowers in connection with sending payment histories and
amortization schedules to Borrowers, faxing documents to Borrowers, providing
credit reference letters to Borrowers, providing a "speed pay" payment option to
Borrowers and for other similar optional services requested by a Borrower and
may retain such fees. The Servicer may also, at its option, collect fees from
Borrowers for returned check processing or other insufficient fund transactions
and may assess such fees from the Borrower's Trust Student Loan payment and
retain such fees.

Section 3.9 Appointment of Subservicer. The Servicer may at any time, upon the
written consent of the Administrator, appoint a subservicer to perform all or
any portion of its obligations as


                                       11
<PAGE>

Servicer hereunder; provided, however, that any applicable Rating Agency
Condition shall have been satisfied in connection therewith; provided further
that the Servicer shall remain obligated and be liable to the Issuer, the
Eligible Lender Trustee, the Indenture Trustee, the Certificateholders and the
Noteholders for the servicing and administering of the Trust Student Loans in
accordance with the provisions hereof without diminution of such obligation and
liability by virtue of the appointment of such subservicer and to the same
extent and under the same terms and conditions as if the Servicer alone were
servicing and administering the Trust Student Loans. The fees and expenses of
the subservicer shall be as agreed between the Servicer and its subservicer from
time to time and none of the Issuer, the Eligible Lender Trustee, the Indenture
Trustee, the Certificateholders or the Noteholders shall have any responsibility
therefor. With respect to satisfying the Rating Agency Condition referred to
above, the term "subservicer" shall be deemed not to include systems providers,
systems developers or systems maintenance contractors, collection agencies,
credit bureaus, lock box providers, mail service providers and other similar
types of service providers.

Section 3.10 Reports. With respect to Trust Student Loans, Servicer shall
prepare reports and data and furnish the following information to the Issuer,
the Administrator, the Eligible Lender Trustee and the Indenture Trustee, unless
otherwise noted, at the specified times:

      (a)   The reports and data listed in Attachment C, at the times indicated
            in the attachment;

      (b)   Within 30 days following the end of each calendar quarter, to the
            Department, owner's request for interest and Special Allowance
            Payments (ED 799);

      (c)   To credit bureaus selected by Servicer, credit bureau reporting in
            accordance with the Higher Education Act;

      (d)   At any time the Eligible Lender Trustee or the Indenture Trustee, as
            the case may be, shall have reasonable grounds to believe that such
            request would be necessary in connection with its performance of its
            duties under related documents, and within five (5) business days of
            receipt of a request therefor, the Servicer shall furnish to the
            Eligible Lender Trustee or to the Indenture Trustee a list of all
            Trust Student Loans (by borrower social security number, type and
            outstanding principal balance) and any additional


                                       12
<PAGE>

            information requested relating to the Trust Student Loans; and

      (e)   From time to time as may be reasonably requested, reports and data
            providing additional information on the Trust Student Loans.

Section 3.11 Covenants and Agreements of the Issuer, Administrator, Eligible
Lender Trustee and Servicer. The Issuer, the Administrator, the Servicer and the
Eligible Lender Trustee each agree that:

      A. Any payment and any communications received at any time by the Issuer,
Administrator and the Eligible Lender Trustee with respect to a Trust Student
Loan shall be immediately transmitted to the Servicer. Such communications shall
include, but not be limited to, requests or notices of loan cancellation,
notices of borrower disqualification, letters, changes in address or status,
notices of death or disability, notices of bankruptcy and forms requesting
deferment of repayment or forbearance.

      B. The Servicer may change any part or all of its equipment, data
processing programs and any procedures and forms in connection with the services
performed hereunder so long as Servicer continues to service the Trust Student
Loans in conformance with the requirements herein. The Servicer shall not make
any material change in its servicing system and operations with respect to the
Trust Student Loans without the prior written consent of the Administrator which
consent will not be unreasonably withheld. Each written request for consent by
the Servicer shall be acted upon promptly by the Administrator. Anything in this
paragraph B. to the contrary notwithstanding, the Servicer will not be required
to request the consent of the Administrator with respect to any changes in the
Servicer's servicing system and operations which the Servicer reasonably
determines are required due to changes in the Higher Education Act or Guarantor
program requirements.

      C. The Eligible Lender Trustee will furnish Servicer with a copy of any
and all Guarantee Agreements relating to the Trust Student Loans serviced
hereunder.

      D. The Servicer may and, at the direction of the Administrator, shall
include marketing or informational material generally provided to borrowers of
loans owned by the Student Loan Marketing Association with communications sent
to a borrower.

      E. The Servicer may, in its discretion, if requested by a borrower of a
Trust Student Loan, arrange for the sale of such


                                       13
<PAGE>

Trust Student Loan to another lender which holds another student loan of such
borrower at a price not less than the Purchase Amount.

      F. The Servicer shall arrange for the sale of a Trust Student Loan to the
Student Loan Marketing Association upon receipt of notice from the Student Loan
Marketing Association that it has received an executed consolidation loan
application from the borrower of such Trust Student Loan. The sale price for
such Trust Student Loan shall equal the Purchase Amount.

Section 3.12 Special Programs. The Servicer shall offer borrowers of the Trust
Student Loans all special programs (e.g., Great Rewards(R), Great Returnssm and
Direct Repaysm), whether or not in existence as of the date of this Agreement,
generally offered to the obligors of comparable loans owned by the Student Loan
Marketing Association and serviced by the Servicer; provided, however, to the
extent any such program is not required by the Higher Education Act and
effectively reduces borrower interest rate or principal balances on the Trust
Student Loans, such special program shall be applied to the Trust Student Loans
only if and to the extent the Issuer receives payment from the Student Loan
Marketing Association (and the Servicer receives notice of such payment) in an
amount sufficient to offset such effective yield reductions. The Student Loan
Marketing Association shall be deemed to be a third party beneficiary of this
Section 3.12 and shall make appropriate arrangements to compensate the Servicer
for increased costs associated with material changes to existing special
programs or the implementation and support of any new special programs.

Section 3.13 Financial Statements. The Servicer shall provide to the
Administrator at any time that the Servicer is not an Affiliate of the
Administrator (a) as soon as possible and in no event more than 120 days after
the end of each fiscal year of the Servicer audited financials as at the end of
and for such year and (b) as soon as possible and in no event more than 30 days
after the end of each quarterly accounting period of the Servicer unaudited
financials as at the end of and for such period.

Section 3.14 Insurance. The Servicer shall maintain or cause to be maintained
insurance with respect to its property and business against such casualties and
contingencies and of such types and in such amounts as is customary in the case
of institutions of the same type and size.

Section 3.15 Administration Agreement. The Servicer agrees to perform all duties
required of the Servicer under the Administration Agreement using that degree of
skill and attention


                                       14
<PAGE>

that the Servicer exercises with respect to its comparable business activities.

Section 3.16 Lender Identification Number. The Eligible Lender Trustee may
permit trusts, other than the Issuer, established by the Seller to securitize
student loans, to use the Department lender identification number applicable to
the Issuer if the servicing agreements with respect to such other trusts include
provisions substantially similar to this paragraph. In such event, the Servicer
may claim and collect Interest Subsidy Payments and Special Allowance Payments
with respect to Trust Student Loans and student loans in such other trusts using
such common lender identification number. Notwithstanding anything herein or in
the Basic Documents to the contrary, any amounts assessed against payments
(including, but not limited to, Interest Subsidy Payments and Special Allowance
Payments) due from the Department to any such other trust using such common
lender identification number as a result of amounts owing to the Department from
the Issuer will be deemed for all purposes hereof and of the Basic Documents
(including for purposes of determining amounts paid by the Department with
respect to the student loans in the Trust and such other trust) to have been
assessed against the Issuer and shall be deducted by the Administrator or the
Servicer and paid to such other trust from any collections made by them which
would otherwise have been payable to the Collection Account for the Issuer. Any
amounts assessed against payments due from the Department to the Issuer as a
result of amounts owing to the Department from such other trust using such
common lender identification number will be deemed to have been assessed against
such other trust and will be deducted by the Administrator or the Servicer from
any collections made by them which would otherwise be payable to the collection
account for such other trust and paid to the Issuer.

                                   Article IV

Section 4.1 Representations of Servicer. The Servicer makes the following
representations on which the Issuer is deemed to have relied in acquiring
(through the Eligible Lender Trustee) the Trust Student Loans and appointing the
Servicer as servicer hereunder. The representations speak as of the execution
and delivery of this Agreement and as of the Closing Date, but shall survive the
sale, transfer and assignment of the Trust Student Loans to the Eligible Lender
Trustee on behalf of the Issuer and the pledge thereof to the Indenture Trustee
pursuant to the Indenture.

      A. Organization and Good Standing. The Servicer is duly organized and

the ownership or lease of property or the conduct of its business (including the
servicing of the Trust Student Loans as required by this Agreement) shall
require such qualifications.

      C. Power and Authority. The Servicer has the power and authority to
execute and deliver this Agreement and to carry out its terms; and the
execution, delivery and performance of this Agreement have been duly authorized
by the Servicer by all necessary action. No registration with or approval of any
governmental agency is required for the due execution and delivery by, and
enforceability against, the Servicer of this Agreement.

      D. Binding Obligation. This Agreement constitutes a legal, valid and
binding obligation of the Servicer enforceable in accordance with its terms
subject to bankruptcy, insolvency and other similar laws affecting creditors
rights generally and subject to equitable principles.

      E. No Violation. The consummation of the transactions contemplated by this
Agreement and the fulfillment of the terms hereof will not conflict with, result
in any breach of any of the terms and provisions of, nor constitute (with or
without notice or lapse of time or both) a default under, the charter or by-laws
of the Servicer, or any indenture, agreement or other instrument to which the
Servicer is a party or by which it shall be bound; nor result in the creation or
imposition of any Lien upon any of its properties pursuant to the terms of any
such indenture, agreement or other instrument (other than this Agreement and the
other Basic Documents); nor violate any law or, to the best of the Servicer's
knowledge, any order, rule or regulation applicable to the Servicer of any court
or of any Federal or state regulatory body, administrative agency or other
governmental instrumentality having jurisdiction over the Servicer or its
properties.

               F. No Proceedings. There are no proceedings or investigations
pending, or, to the Servicer's best knowledge, threatened, before any court,
regulatory body, administrative agency or other governmental instrumentality
having jurisdiction over the Servicer or its properties: (i) asserting the


                                       16
<PAGE>

invalidity of this Agreement or any of the other Basic Documents to which the
Servicer is a party, (ii) seeking to prevent the consummation of any of the
transactions contemplated by this Agreement or any of the other Basic Documents
to which the Servicer is a party, (iii) seeking any determination or ruling that
could reasonably be expected to have a material and adverse effect on the
performance by the Servicer of its obligations under, or the validity or
enforceability of, this Agreement or any of the other Basic Documents to which
the Servicer is a party, or (iv) relating to the Servicer and which might
adversely affect the Federal or state income tax attributes of the Notes or the
Certificates.

Section 4.2 Indemnities of Servicer. The Servicer shall be liable in accordance
herewith only to the extent of the obligations specifically undertaken by the
Servicer under this Agreement.

      The Servicer shall pay for any loss, liability or expense, including
reasonable attorneys' fees, that may be imposed on, incurred by or asserted
against the Issuer or the Eligible Lender Trustee by the Department pursuant to
the Higher Education Act, to the extent that such loss, liability or expense
arose out of, or was imposed upon the Issuer through, the negligence, willful
misfeasance or bad faith of the Servicer in the performance of its obligations
and duties under this Agreement or by reason of the reckless disregard of its
obligations and duties under this Agreement, where the final determination that
any such loss, liability or expense arose out of, or was imposed upon the Issuer
or the Eligible Lender Trustee through, any such negligence, willful
misfeasance, bad faith or recklessness on the part of the Servicer is
established by a court of law, by an arbitrator or by way of settlement agreed
to by the Servicer. Notwithstanding the foregoing, if the Servicer is rendered
unable, in whole or in part, by a force outside the control of the parties
hereto (including acts of God, acts of war, fires, earthquakes, hurricanes,
floods and other disasters) to satisfy its obligations under this Agreement, the
Servicer shall not be deemed to have breached any such obligation upon delivery
of written notice of such event to the other parties hereto, for so long as the
Servicer remains unable to perform such obligation as a result of such event.

      For purposes of this Section, in the event of the termination of the
rights and obligations of Sallie Mae Servicing Corporation (or any successor
thereto pursuant to Section 4.3) as Servicer pursuant to Section 5.1, or a
resignation by such Servicer pursuant to this Agreement, such Servicer shall be
deemed to be the Servicer pending appointment of a successor Servicer pursuant
to Section 5.2.


                                       17
<PAGE>

      Liability of the Servicer under this Section shall survive the resignation
or removal of the Eligible Lender Trustee or the Indenture Trustee or the
termination of this Agreement. If the Servicer shall have made any payments
pursuant to this Section and the Person to or on behalf of whom such payments
are made thereafter collects any of such amounts from others, such Person shall
promptly repay such amounts to the Servicer, without interest.

Section 4.3 Merger or Consolidation of, or Assumption of the Obligations of,
Servicer. The Servicer hereby agrees that, upon (a) any merger or consolidation
of the Servicer into another Person, (b) any merger or consolidation to which
the Servicer shall be a party resulting in the creation of another Person or (c)
any Person succeeding to the properties and assets of the Servicer substantially
as a whole, the Servicer shall (i) cause such Person (if other than the
Servicer) to execute an agreement of assumption to perform every obligation of
the Servicer hereunder, (ii) deliver to the Eligible Lender Trustee and
Indenture Trustee an Officers' Certificate and an Opinion of Counsel each
stating that such consolidation, merger or succession and such agreement of
assumption comply with this Section and that all conditions precedent provided
for in this Agreement relating to such transaction have been complied with,
(iii) cause the Rating Agency Condition to have been satisfied with respect to
such transaction and (iv) cure any existing Servicer Default or any continuing
event which, after notice or lapse of time or both, would become a Servicer
Default. Upon compliance with the foregoing requirements, such Person shall be
the successor to the Servicer under this Agreement without further act on the
part of any of the parties to this Agreement.

Section 4.4 Limitation on Liability of Servicer. The Servicer shall not be under
any liability to the Issuer, the Noteholders, the Certificateholders, the
Administrator, the Eligible Lender Trustee or the Indenture Trustee except as
provided under this Agreement, for any action taken or for refraining from the
taking of any action pursuant to this Agreement, for errors in judgment, for any
incorrect or incomplete information provided by schools, borrowers, Guarantors
and the Department, for the failure of any party to this Servicing Agreement or
any other Basic Document to comply with its respective obligations hereunder or
under any other Basic Document or for any losses attributable to the insolvency
of any Guarantor; provided, however, that this provision shall not protect the
Servicer against its obligation to purchase Student Loans from the Trust
pursuant to Section 3.5 hereof or to pay to the Trust amounts required pursuant
to Section 3.5 hereof or against any liability that would otherwise be imposed
by reason of willful misfeasance, bad faith or


                                       18
<PAGE>

negligence in the performance of duties or by reason of reckless disregard of
obligations and duties under this Agreement. The Servicer may rely in good faith
on any document of any kind prima facie properly executed and submitted by any
person respecting any matters arising under this Agreement.

      Except as provided in this Agreement, the Servicer shall not be under any
obligation to appear in, prosecute or defend any legal action where it is not
named as a party; provided, however, that the Servicer may undertake any
reasonable action that it may deem necessary or desirable in respect of this
Agreement and the other Basic Documents and the rights and duties of the parties
to this Agreement and the other Basic Documents and the interests of the
Certificateholders and the Noteholders. To the extent that the Servicer is
required to appear in or is made a defendant in any legal action or other
proceeding relating to the servicing of the Trust Student Loans, the Issuer
shall indemnify and hold the Servicer harmless from all cost, liability or
expense of the Servicer not arising out of or relating to the failure of the
Servicer to comply with the terms of this Agreement.

Section 4.5 Sallie Mae Servicing Corporation Not To Resign as Servicer. Subject
to the provisions of Section 4.3, Sallie Mae Servicing Corporation shall not
resign from the obligations and duties hereby imposed on it as Servicer under
this Agreement except upon determination that the performance of its duties
under this Agreement are no longer permissible under applicable law. Notice of
any such determination permitting the resignation of Sallie Mae Servicing
Corporation shall be communicated to the Eligible Lender Trustee and the
Indenture Trustee at the earliest practicable time (and, if such communication
is not in writing, shall be confirmed in writing at the earliest practicable
time) and any such determination shall be evidenced by an Opinion of Counsel to
such effect delivered to the Eligible Lender Trustee and the Indenture Trustee
concurrently with or promptly after such notice. No such resignation shall
become effective until the Indenture Trustee or a successor Servicer shall have
assumed the responsibilities and obligations of Sallie Mae Servicing Corporation
in accordance with Section 5.2.

                                    Article V

Section 5.1 Servicer Default. If any one of the following events (a "Servicer
Default") shall occur and be continuing:

      (1)   any failure by the Servicer (i) to deliver to the Indenture Trustee
            for deposit in the Trust Accounts any payment required by the Basic
            Documents to which the Servicer is a signatory or (ii) in the event
            that daily deposits into the Collection Account are not required,


                                       19
<PAGE>

            to deliver to the Administrator any payment required by the Basic
            Documents, which failure in case of either clause (i) or (ii)
            continues unremedied for five Business Days after written notice of
            such failure is received by the Servicer from the Eligible Lender
            Trustee, the Indenture Trustee or the Administrator or five Business
            Days after discovery of such failure by an officer of the Servicer;
            or

      (2)   any failure by the Servicer duly to observe or to perform in any
            material respect any other covenant or agreement of the Servicer set
            forth in this Agreement or any other Basic Document to which the
            Servicer is a signatory, which failure shall (i) materially and
            adversely affect the rights of Noteholders or Certificateholders and
            (ii) continues unremedied for a period of 60 days after the date on
            which written notice of such failure, requiring the same to be
            remedied, shall have been given (A) to the Servicer by the Indenture
            Trustee, the Eligible Lender Trustee or the Administrator or (B) to
            the Servicer, and to the Indenture Trustee and the Eligible Lender
            Trustee by the Noteholders or Certificateholders, as applicable,
            representing not less than 25% of the Outstanding Amount of the
            Notes or not less than 25% of the outstanding Certificate Principal
            Balance provided, however any breach of Sections 3.1, 3.2, 3.3 or
            3.4 shall not be deemed a Servicer Default so long as the Servicer
            is in compliance with its repurchase and reimbursement obligations
            under Section 3.5; or

      (3)   an Insolvency Event occurs with respect to the Servicer; or

      (4)   any failure by the Servicer to comply with any requirements under
            the Higher Education Act resulting in a loss of its eligibility as a
            third-party servicer;

then, and in each and every case, so long as the Servicer Default shall not have
been remedied, either the Indenture Trustee, or the Noteholders of Notes
evidencing not less than 25% of the Outstanding Amount of the Notes, by notice
then given in writing to the Servicer (and to the Indenture Trustee and the
Eligible Lender Trustee if given by the Noteholders) may terminate all the
rights and obligations (other than the obligations set forth in Section 3.5 and
Section 4.2) of the Servicer under this Agreement. As of the effective date of
termination of the Servicer, all authority and power of the Servicer under this
Agreement, whether with respect to the Notes, the Certificates or the Trust
Student Loans or otherwise, shall, without further action, pass to and be vested
in the Indenture Trustee or such


                                       20
<PAGE>

successor Servicer as may be appointed under Section 5.2. The predecessor
Servicer shall cooperate with the successor Servicer, the Indenture Trustee and
the Eligible Lender Trustee in effecting the termination of the responsibilities
and rights of the predecessor Servicer under this Agreement, including the
transfer to the successor Servicer for administration by it of all cash amounts
that shall at the time be held by the predecessor Servicer for deposit, or shall
thereafter be received by it with respect to a Trust Student Loan. All
reasonable costs and expenses (including attorneys' fees) incurred in connection
with transferring the Trust Student Loan Files to the successor Servicer and
amending this Agreement and any other Basic Documents to reflect such succession
as Servicer pursuant to this Section shall be paid by the predecessor Servicer
(other than the Indenture Trustee acting as the Servicer under this Section 5.1)
upon presentation of reasonable documentation of such costs and expenses. Upon
receipt of notice of the occurrence of a Servicer Default, the Eligible Lender
Trustee shall give notice thereof to the Rating Agencies.

Section 5.2 Appointment of Successor.

      A. Upon receipt by the Servicer of notice of termination pursuant to
Section 5.1, or the resignation by the Servicer in accordance with the terms of
this Agreement, the predecessor Servicer shall continue to perform its functions
as Servicer under this Agreement, in the case of termination, only until the
date specified in such termination notice or, if no such date is specified in a
notice of termination, until receipt of such notice and, in the case of
resignation, until the Indenture Trustee or a successor Servicer shall have
assumed the responsibilities and duties of Sallie Mae Servicing Corporation. In
the event of the termination hereunder of the Servicer, the Issuer shall appoint
a successor Servicer acceptable to the Indenture Trustee, and the successor
Servicer shall accept its appointment by a written assumption in form acceptable
to the Indenture Trustee. In the event that a successor Servicer has not been
appointed at the time when the predecessor Servicer has ceased to act as
Servicer in accordance with this Section, the Indenture Trustee without further
action shall automatically be appointed the successor Servicer and the Indenture
Trustee shall be entitled to the Servicing Fee and any Carryover Servicing Fees.
Notwithstanding the above, the Indenture Trustee shall, if it shall be unwilling
or legally unable so to act, appoint or petition a court of competent
jurisdiction to appoint any established institution whose regular business shall
include the servicing of student loans, as the successor to the Servicer under
this Agreement; provided, however, that such right to appoint or to petition for
the appointment of any such successor Servicer shall in no event relieve the
Indenture Trustee from any


                                       21
<PAGE>

obligations otherwise imposed on it under the Basic Documents until such
successor has in fact assumed such appointment.

      B. Upon appointment, the successor Servicer (including the Indenture
Trustee acting as successor Servicer) shall be the successor in all respects to
the predecessor Servicer and shall be subject to all the responsibilities,
duties and liabilities placed on the predecessor Servicer that arise thereafter
or are related thereto and shall be entitled to an amount agreed to by such
successor Servicer (which shall not exceed the Servicing Fee unless the Rating
Agency Condition is satisfied with respect to such compensation arrangements)
and all the rights granted to the predecessor Servicer by the terms and
provisions of this Agreement.

      C. The Servicer may not resign unless it is prohibited from serving as
such by law as evidenced by an Opinion of Counsel to such effect delivered to
the Indenture Trustee and the Eligible Lender Trustee. Notwithstanding the
foregoing or anything to the contrary herein or in the other Basic Documents,
the Indenture Trustee, to the extent it is acting as successor Servicer pursuant
hereto and thereto, shall be entitled to resign to the extent a qualified
successor Servicer has been appointed and has assumed all the obligations of the
Servicer in accordance with the terms of this Agreement and the other Basic
Documents.

Section 5.3 Notification to Noteholders and Certificateholders. Upon any
termination of, or appointment of a successor to, the Servicer pursuant to this
Article V, the Eligible Lender Trustee shall give prompt written notice thereof
to Certificateholders and the Indenture Trustee shall give prompt written notice
thereof to Noteholders and the Rating Agencies (which, in the case of any such
appointment of a successor, shall consist of prior written notice thereof to the
Rating Agencies).

Section 5.4 Waiver of Past Defaults. The Noteholders of Notes evidencing a
majority of the Outstanding Amount of the Notes (or the Certificateholders of
Certificates evidencing not less than a majority of the outstanding Certificate
Principal Balance, in the case of any default which does not adversely affect
the Indenture Trustee or the Noteholders) may, on behalf of all Noteholders and
Certificateholders, waive in writing any default by the Servicer in the
performance of its obligations hereunder and any consequences thereof, except a
default in making any required deposits to or payments from any of the Trust
Accounts (or giving instructions regarding the same) in accordance with this
Agreement. Upon any such waiver of a past default, such default shall cease to
exist, and any Servicer Default arising therefrom shall be deemed to have been
remedied for every purpose of this Agreement and the Administration Agreement.
No such waiver shall


                                       22
<PAGE>

extend to any subsequent or other default or impair any right consequent
thereto.

Section 6.1 Amendment.

      A. This Agreement may be amended by the Servicer, the Issuer, the

adding any provisions to or changing in any manner or eliminating any of the
provisions in this Agreement; provided, however, that such action shall not, as

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 with respect to 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 Principal Balance, the
Noteholders or the Certificateholders of which are required to consent to any
such amendment, without the consent of all outstanding Noteholders and
Certificateholders.

Noteholders pursuant to paragraph B. to approve the particular form of any
proposed amendment or consent, but it shall be sufficient if such consent shall
approve the substance thereof.

                                SCHEDULE OF FEES

      The Servicer will receive a Primary Servicing Fee and a Carryover
Servicing Fee (together, the "Servicing Fee"). The "Primary Servicing Fee" for
any month is an amount equal to the sum of 1/12th of 0.90% of the outstanding
principal amount of the Trust Student Loans other than Consolidation Loans plus
1/12th of 0.50% of the outstanding principal amount of the Trust Student Loans
that are Consolidation Loans, in each case as of the last day of the preceding
calendar month, plus any such amounts from prior Monthly Servicing Payment Dates
that remain unpaid. The Primary Servicing Fee will be payable out of Available
Funds and amounts on deposit in the Reserve Account on the 25th day of each
month (or, if any such date is not a business day, on the next succeeding
business day), commencing May 26, 2000 (each, a "Monthly Servicing Payment
Date"). The "Carryover Servicing Fee" is the sum of (a) the amount of certain
increases in the costs incurred by the Servicer which are agreed to pursuant to
Section 3.8 of the Servicing Agreement, (b) any Conversion Fees, Transfer Fees
and Removal Fees (as defined below) incurred since the last Distribution Date
and (c) any amounts described in (a) and (b) above that remain unpaid from prior
Distribution Dates plus interest on such amounts for the period from the
Distribution Date on which such amounts become due to the date such amounts are
paid in full at a rate per annum for each Interest Period (as defined below)
equal to the sum of (a) the average accepted auction price (expressed on a bond
equivalent basis) for 91-day Treasury Bills sold at the most recent 91-day
Treasury Bill auction prior to the Interest Period as reported by the U.S.
Treasury Department and (b) 2.00%.

      "Interest Period" shall mean the period from each Distribution Date
through the day before the next Distribution Date. The Carryover Servicing Fee
will be payable to the Servicer on each succeeding Distribution Date out of
Available Funds after payment on such Distribution Date of the Primary Servicing
Fee, the Administration Fee, the Swap Fees, the Noteholders' Distribution
Amount, the Certificateholders' Distribution Amount, the amount, if any,
necessary to be deposited in the Reserve Account to reinstate the balance
thereof to the Specified Reserve Account Balance and the Swap Payments. On the

rata portion of the Primary Servicing Fee for the period from the Closing Date

to the Trust Estate which Student Loan is not serviced on the Servicer's system
unless such Student Loan is being substituted into the Trust Estate by the
Servicer pursuant to Section 3.5 of this Agreement. The Conversion Fee is equal
to the greater of $17.00 per account or the Servicer's verifiable costs plus
15%.

      Servicer will be paid a fee ("Transfer Fee") for any Student Loan
transferred in or out of the Trust Estate which is at the time of transfer being
serviced on the Servicer's system (regardless of the owner) unless such Student
Loans are being removed or added to the Trust in order to comply with the
Servicer's purchase/substitution obligation under Section 3.5 of this Agreement.
The Transfer Fee is equal to $4.00 per account transaction.

      Servicer will be paid a fee ("Removal Fee") for performing all activities
required to remove a Trust Student Loan from the Servicer's system to another

of the Servicer pursuant to Section 5.1 of this Agreement. The Removal Fee is
equal to $10.00 per account plus any verifiable direct expenses incurred for
shipping such Trust Student Loan to the new servicer.
