Ladies and Gentlemen:

                  SLM Funding Corporation, a Delaware corporation (the

terms and conditions stated herein and in the Underwriting Agreement, dated

Mae, on the one hand, and Morgan Stanley & Co. Incorporated, on the other hand,
that the Company will cause the trust (the "Trust") formed pursuant to the Trust

Bank Delaware, as trustee (the "Eligible Lender Trustee"), to issue and sell to

                  Except as modified pursuant to Schedule II hereto, each of the

opposite the name of such Underwriter in Schedule I hereto, less the principal
amount of Designated Securities covered by Delayed Delivery Contracts, if any,

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

document may otherwise lawfully be issued or passed on.

please 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

MORGAN STANLEY & CO. INCORPORATED

NEW YORK, NEW YORK  10036

                                                               December 21, 1999

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
December 21, 1999 (the "Underwriting Agreement"), between the Company and Sallie
Mae, on the one hand, and Morgan Stanley & Co. Incorporated, on the other hand,
that the Company will cause the trust (the "Trust") formed pursuant to the Trust
Agreement dated as of December 1, 1999 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 hereto (the "Underwriters") the Student
Loan-Backed Certificates (the "Certificates") specified in Schedule II hereto
(the "Designated Securities"). The Certificates will be issued pursuant to the
Trust Agreement.

                  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 shall be deemed to be a
representation or warranty as of the date of the Underwriting Agreement in
relation to the Prospectus (as therein defined), and also a representation and
warranty as of the date of this Pricing Agreement in relation to the Prospectus
as amended or supplemented relating to the Designated Securities which are the
subject of this Pricing Agreement. Each reference to the Representatives herein
and in the provisions of the Underwriting Agreement so incorporated by reference
shall be deemed to refer to you. Unless otherwise defined herein, terms defined
in 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.


<PAGE>

                  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 December
28, 1999, 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 Services Act 1986
(Investment Advertisements) (Exemptions) Order 1996 or is a person to whom such
document may otherwise lawfully be issued or passed on.

                  If the foregoing is in accordance with your understanding,
please sign and return to us 6 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

shall be submitted to the Company and Sallie Mae for examination upon request,

MORGAN STANLEY & CO. INCORPORATED
1585 BROADWAY
NEW YORK, NEW YORK  10036


Ladies and Gentlemen:

         From time to time the Student Loan Marketing Association ("Sallie
Mae"), a corporation formed under the laws of the United States, and SLM Funding
Corporation, a Delaware corporation and a wholly-owned subsidiary of Sallie Mae
(the "Company"), propose to enter into one or more Pricing Agreements (each a
"Pricing Agreement") in the form of Annex I hereto, with such additions and
deletions as the parties thereto may determine. Subject to the terms and
conditions stated herein and therein, the Company proposes to cause the Trust
specified in the applicable Pricing Agreement to issue and sell to the firms
named in Schedule I to the applicable Pricing Agreement (such firms constituting
the "Underwriters" with respect to such Pricing Agreement and the securities
specified therein) certain of such Trust's Student Loan-Backed Notes (the
"Notes") specified in Schedule II to such Pricing Agreement (with respect to
such Pricing Agreement, the "Designated Securities"), less the principal amount
of Designated Securities covered by Delayed Delivery Contracts, if any, as
provided in Section 3 hereof and as may be specified in Schedule II to such
Pricing Agreement (with respect to such Pricing Agreement, any Designated
Securities to be covered by Delayed Delivery Contracts are herein sometimes
referred to as "Contract Securities" and the Designated Securities to be
purchased by the Underwriters (after giving effect to the deduction, if any, for
Contract Securities) are herein sometimes referred to as "Underwriters'
Securities").

         The Securities may be sold from time to time in one or more Series.
Each Series of Securities, which will include one or more classes of Notes and
one or more classes of Student Loan-Backed Certificates (the "Certificates,"
and, together with the Notes, the "Securities") will be issued by a Trust to be
formed with respect to such Series (each, a "Trust"). Each Trust will be formed
pursuant to a trust agreement (a "Trust Agreement") to be entered into between
the Company and the Eligible Lender Trustee specified in the related Pricing
Agreement (the "Eligible Lender Trustee"). The Notes of each Series will be
issued and secured pursuant to an indenture (an "Indenture") between the Trust
and the Indenture Trustee specified in the related Pricing Agreement (the
"Indenture Trustee"). The Certificates of a


<PAGE>


Series will be issued pursuant to the related Trust Agreement and will represent
fractional undivided interests in the Trust created thereby. The property of
each Trust will include, among other things, educational student loans to
students and/or parents of dependent students ("Student Loans").

         With respect to each Trust, (i) the Company will acquire the related
Student Loans from Sallie Mae pursuant to a Purchase Agreement and (ii) the
Company will sell the related Student Loans to such Trust pursuant to a Sale
Agreement, with the related Eligible Lender Trustee holding legal title thereto.
With respect to each Series, Sallie Mae Servicing Corporation, as servicer (the
"Servicer") will enter into a servicing agreement (a "Servicing Agreement") with
the Trust, the Administrator, the Eligible Lender Trustee and the Indenture
Trustee with respect to the related Student Loans. Sallie Mae, as administrator
(in such capacity, the "Administrator"), has entered into a Master
Administration Agreement with the Company dated as of May 1, 1997 and, as
contemplated by the terms of the Master Administration Agreement, will enter
into an Administration Agreement Supplement among the Company, the Trust, the
Eligible Lender Trustee, the Servicer and the Indenture Trustee with respect to
the Student Loans to be held by the Trust (the Master Administration Agreement,
as supplemented by the Administration Agreement Supplement, the "Administration
Agreement").

         The terms and conditions of any particular issuance of Designated
Securities shall be as specified in the Pricing Agreement relating thereto and
in or pursuant to the related Indenture.

         Capitalized terms used but not defined herein or in any Pricing
Agreement shall have the meanings ascribed thereto in the related Indenture.

         1. Particular sales of Designated Securities may be made from time to
time to the Underwriters of such Securities, for whom the firms designated as
representatives of the Underwriters of such Securities in the Pricing Agreement
relating thereto will act as representatives (the "Representatives"). The term
"Representatives" also refers to a single firm acting as sole representative of
the Underwriters and to an Underwriter or Underwriters who act without any firm
being designated as its or their representatives. This Underwriting Agreement
shall not be construed as an obligation of the Company to sell any of the
Securities or as an obligation of any of the Underwriters to purchase the
Securities. The obligation of the Company to issue and sell any of the
Securities and the obligation of any of the Underwriters to purchase any of the
Securities shall be evidenced by the Pricing Agreement with respect to the
Designated Securities specified therein. Each Pricing Agreement shall specify
the aggregate principal amount of such Designated Securities, the initial public
offering price of such Designated Securities, the purchase price to the
Underwriters of such Designated Securities, the names of the Underwriters of
such Designated Securities, the names of the Representatives of such
Underwriters and the principal amount of such Designated Securities to be
purchased by each Underwriter and whether any of such Designated Securities
shall be covered by Delayed Delivery Contracts (as defined in Section 3 hereof)
and shall set forth the date, time and manner of delivery of such Designated
Securities and payment therefor. The



                                       2
<PAGE>


Pricing Agreement shall also specify (to the extent not set forth in the
Indenture and the registration statement and prospectus with respect thereto)
the terms of such Designated Securities. A Pricing Agreement shall be in the
form of an executed writing (which may be in counterparts), and may be evidenced
by an exchange of telegraphic communications or any other rapid transmission
device designed to produce a written record of communications transmitted. The
obligations of the Underwriters under this Agreement and each Pricing Agreement
shall be several and not joint.

         each in the form heretofore delivered to the Representatives); and no
         stop order suspending the effectiveness of such registration statement
         has been issued and no proceeding for that purpose has been initiated

         filing);

                (b) The documents incorporated by reference in the Prospectus,
         when they became effective or were filed with the Commission, as the
         case may be, conformed in all material respects to the requirements of
         the Act, the Exchange Act and the Trust Indenture Act of 1939, as
         amended (the "Trust Indenture Act"), as applicable, and the rules and

         to such Designated Securities;

                (c) The Registration Statement and the Prospectus conform, and
         any further amendments or supplements to the Registration Statement or
         the Prospectus will conform, in all material respects to the
         requirements of the Act and the Trust Indenture Act, as applicable, and
         the rules and regulations of the Commission thereunder and do not and
         will not, as of the applicable effective date as to the Registration
         Statement and any amendment thereto and as of the applicable filing
         date as to the Prospectus and any amendment or supplement thereto,
         contain an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading; PROVIDED, HOWEVER, that this
         representation and

         warranty shall not apply to any statements or omissions made in
         reliance upon and in conformity with information furnished in writing

         subsidiaries has sustained since the date of the financial statements
         included in Sallie Mae's most recently published Information Statement
         any material loss or interference with its business from fire,

         insurance, or from any labor dispute or court or governmental action,
         order or decree, otherwise than as set forth or contemplated in such
         Information Statement; and, since such date, there has not been any
         material adverse change in the capital stock or long-term debt of the
         Company or Sallie Mae or any of its subsidiaries or any material
         adverse change, or any development involving a prospective material
         adverse change, in or affecting the general affairs, management,
         financial position, shareholders' equity or results of operations of
         the Company or Sallie Mae or any of its subsidiaries or the
         transactions contemplated hereby, otherwise than as set forth or
         contemplated in such Information Statement;

                (e) The Company has been duly incorporated and is validly
         existing as a corporation in good standing under the laws of the state
         of Delaware, with power and authority (corporate and other) to own its
         properties and conduct its business as described in the Prospectus and
         to consummate the transactions contemplated therein and herein, and is
         a wholly-owned subsidiary of Sallie Mae. Sallie Mae has been duly

         with power and authority (corporate and otherwise) to own its
         properties and conduct its business as described in the Prospectus and

         wholly-owned subsidiary of Sallie Mae.

               (f) All of the issued shares of capital stock of the Company have

         non-assessable and are owned beneficially and of record by Sallie Mae;

                (g) This Agreement has been, and each Pricing Agreement with
         respect to the Designated Securities upon its execution and delivery by
         the Company and Sallie Mae will have been, duly authorized, executed
         and delivered by the Company and Sallie Mae. The Securities have been
         duly authorized, and, when Designated Securities are issued and
         delivered pursuant to this Agreement and the Pricing Agreement with
         respect to such Designated Securities, and, in the case of any Contract

         Designated Securities and Contract Securities will have been duly
         executed, authenticated, issued and delivered. The Designated
         Securities will constitute valid and legally binding obligations of
         the related Trust entitled to the benefits provided by the Indenture,
         which will be substantially in the form filed as an exhibit to the
         Registration Statement. The Indenture has been duly authorized and
         duly qualified under the Trust Indenture Act. The related Certificates
         are intended to represent undivided ownership interests in the Trust
         created by the Trust Agreement, which will be substantially in the
         form filed as an exhibit to the Registration Statement, and will be
         entitled to the benefits provided by the Trust Agreement. At the Time
         of Delivery (as defined in Section 4 hereof) for the Designated
         Securities, the Indenture and the Trust Agreement will each constitute
         a valid and legally binding instrument, enforceable in accordance with
         its terms, subject, as to enforcement, to bankruptcy, insolvency,
         reorganization and other laws of general applicability relating to or
         affecting creditors' rights and to general equity principles. The
         Indenture and Trust Agreement conform, and the Designated Securities
         and the related Certificates will conform, to the descriptions thereof
         contained in the Prospectus as amended or supplemented with respect to
         the Designated Securities;

                (h) The issue and sale of the Securities and the compliance by
         the Company with all of the provisions of the Securities, the
         Indenture, the Trust Agreement, each of the Delayed Delivery Contracts,
         this Agreement and any Pricing Agreement, and the consummation of the
         transactions herein and therein contemplated will not conflict with or
         result in a breach or violation of any of the terms or provisions of,
         or constitute a default under, any indenture, mortgage, deed of trust,
         loan agreement or other agreement or instrument to which the Company or
         Sallie Mae is a party or by which the Company or Sallie Mae is bound or
         to which any of the property or assets of the Company or Sallie Mae is
         subject, nor will such action result in any violation of the provisions
         of the Company's Certificate of Incorporation or By-laws, Sallie Mae's
         charter, enabling legislation or By-laws, or any statute or any order,
         rule or regulation of any court or governmental agency or body having
         jurisdiction over the Company or Sallie Mae or any of their properties;
         and no consent, approval, authorization, order, registration or
         qualification of or with any such court or governmental agency or body
         is required for the issue and sale of the Securities or the
         consummation by the Company or Sallie Mae of the transactions
         contemplated by this Agreement or any Pricing Agreement or the
         Indenture or any Delayed Delivery Contract, except such as have been,
         or will have been prior to the Time of Delivery, obtained under the Act
         and the Trust Indenture Act and such consents, approvals,
         authorizations, registrations or qualifications as may be required
         under state securities or Blue Sky laws in connection with the purchase
         and distribution of the Designated Securities by the Underwriters;

                (i) The statements set forth in the Prospectus under the
         captions "Description of the Notes" and "Description of the
         Certificates" and set forth in the Prospectus Supplement under the
         caption "Description of the Securities," insofar as they purport to



                                       6
<PAGE>


         constitute a summary of the terms of the Notes and the Certificates,
         are accurate, complete and fair;

                (j) Sallie Mae is not in violation of its charter as set forth
         in its enabling legislation or By-laws, and the Company is not in
         violation of its Certificate of Incorporation or By-laws, and neither
         Sallie Mae nor the Company is in default in the performance or
         observance of any material obligation, agreement, covenant or condition
         contained in any indenture, mortgage, deed of trust, loan agreement,
         lease or other agreement or instrument to which it is a party or by
         which it or any of its properties may be bound;

                (k) Other than as set forth in the Prospectus or in Sallie Mae's
         most recently published Information Statement, there are no legal or
         governmental proceedings pending to which the Company or Sallie Mae or
         any of its subsidiaries is a party or of which any property of the
         Company or Sallie Mae or any of its subsidiaries is the subject which,
         if determined adversely to the Company or Sallie Mae or any of its
         subsidiaries, would individually or in the aggregate have a material
         adverse effect on the current or future consolidated financial
         position, shareholders' equity or results of operations of the Company
         or Sallie Mae or any of its subsidiaries or on the consummation of the
         transactions contemplated hereby; and, to the best of the Company's and
         Sallie Mae's knowledge, no such proceedings are threatened or
         contemplated by governmental authorities or threatened by others;

                (l) The Company is not and, after giving effect to the offering
         and sale of the Securities, will not be an "investment company" or an
         entity "controlled" by an "investment company", as such terms are
         defined in the Investment Company Act of 1940, as amended (the
         "Investment Company Act");

                (m) Neither the Company, Sallie Mae nor any of their affiliates
         does business with the government of Cuba or with any person or
         affiliate located in Cuba within the meaning of Section 517.075,
         Florida Statutes;

                (n) Arthur Anderson LLP are independent public accountants as
         required by the Act and the rules and regulations of the Commission
         thereunder;

                (o) At the Time of Delivery of the Designated Securities, Sallie
         Mae's representations and warranties in the related Purchase Agreement
         and the Administration Agreement, the Company's representations and
         warranties in the related Sale Agreement and Trust Agreement and the
         Servicer's representations and warranties in the Servicing Agreement
         will be true and correct in all material respects; and

                (p) In the event any of the Securities are purchased pursuant to
         Delayed Delivery Contracts, each of such Delayed Delivery Contracts has
         been duly authorized by the Company and Sallie Mae and, when executed
         and delivered by the Company and the purchaser named therein, will
         constitute a valid and legally binding agreement of the Company
         enforceable in accordance with its terms, subject, as to enforcement,
         to



                                       7
<PAGE>


         bankruptcy, insolvency, reorganization and other laws of general
         applicability relating to or affecting creditors' rights and to
         general equity principles; and any Delayed Delivery Contracts conform
         to the description thereof in the Prospectus.

         3. Upon the execution of the Pricing Agreement applicable to any
Designated Securities and authorization by the Representatives of the release of
the Underwriters' Securities, the several Underwriters propose to offer such
Underwriters' Securities for sale upon the terms and conditions set forth in the
Prospectus as amended or supplemented.

         The Company may specify in Schedule II to the Pricing Agreement
applicable to any Designated Securities that the Underwriters are authorized to
solicit offers to purchase Designated Securities from the Company pursuant to
delayed delivery contracts (herein called "Delayed Delivery Contracts"),
substantially in the form of Annex III attached hereto but with such changes
therein as the Representatives and the Company may authorize or approve. If so
specified, the Underwriters will endeavor to make such arrangements, and as
compensation therefor the Company will pay to the Representatives, for the
accounts of the Underwriters, at the Time of Delivery, such commission, if any,
as may be set forth in such Pricing Agreement. Delayed Delivery Contracts, if
any, are to be with investors of the types described in the Prospectus and
subject to other conditions therein set forth. The Underwriters will not have
any responsibility with respect to the validity or performance of any Delayed
Delivery Contracts.

         The principal amount of Contract Securities to be deducted from the
principal amount of Designated Securities to be purchased by each Underwriter as
set forth in Schedule I to the Pricing Agreement applicable to such Designated
Securities shall be, in each case, the principal amount of Contract Securities
which the Company has been advised by the Representatives have been attributed
to such Underwriter, provided that, if the Company has not been so advised, the
amount of Contract Securities to be so deducted shall be, in each case, that
proportion of Contract Securities which the principal amount of Designated
Securities to be purchased by such Underwriter under such Pricing Agreement
bears to the total principal amount of the Designated Securities (rounded as the
Representatives may determine). The total principal amount of Underwriters'
Securities to be purchased by all the Underwriters pursuant to such Pricing
Agreement shall be the total principal amount of Designated Securities set forth
in Schedule I to such Pricing Agreement less the principal amount of the
Contract Securities. The Company will deliver to the Representatives not later
than 3:30 p.m., New York City time, on the third business day preceding the Time
of Delivery specified in the applicable Pricing Agreement (or such other time
and date as the Representatives and the Company may agree upon in writing), a
written notice setting forth the principal amount of Contract Securities.

         4. Underwriters' Securities to be purchased by each Underwriter
pursuant to the Pricing Agreement relating thereto, in the form specified in
such Pricing Agreement, and in such authorized denominations and registered in
such names as the Representatives may request upon at least forty-eight hours'
prior notice to the Company, shall be delivered by or



                                       8
<PAGE>


on behalf of the Company to the Representatives for the account of such
Underwriter, against payment by such Underwriter or on its behalf of the
purchase price therefor by wire transfer or by certified or official bank check
or checks, payable to the order of the Company in the funds specified in such
Pricing Agreement, all in the manner and at the place and time and date
specified in such Pricing Agreement or at such other place and time and date as
the Representatives and the Company may agree upon in writing, such time and
date being herein called the "Time of Delivery" for such Securities.

         Concurrently with the delivery of and payment for the Underwriters'
Securities, the Company will deliver to the Representatives for the accounts of
the Underwriters a check payable to the order of the party designated in the
Pricing Agreement relating to such Underwriters' Securities in the amount of any
compensation payable by the Company to the Underwriters in respect of any
Delayed Delivery Contracts as provided in Section 3 hereof and the Pricing
Agreement relating to such Securities.

         5. The Company agrees with each of the Underwriters of any Designated
Securities, and Sallie Mae agrees with such Underwriters that it will cause the
Company:

                (a) To prepare the Prospectus as amended or supplemented in
         relation to the applicable Designated Securities in a form approved by
         the Representatives and to file such Prospectus pursuant to Rule 424(b)
         under the Act not later than the Commission's close of business on the
         second business day following the execution and delivery of the Pricing
         Agreement relating to the applicable Designated Securities or, if
         applicable, such earlier time as may be required by Rule 424(b); to
         make no further amendment or any supplement to the Registration
         Statement or Prospectus as amended or supplemented after the date of
         the Pricing Agreement relating to such Designated Securities and prior
         to the Time of Delivery for such Designated Securities which shall be
         disapproved by the Representatives for such Designated Securities
         promptly after reasonable notice thereof; to advise the Representatives
         promptly of any such amendment or supplement after such Time of
         Delivery and furnish the Representatives with copies thereof; to file
         promptly all reports and any definitive proxy or information statements
         required to be filed by the Company with the Commission pursuant to
         Section 13(a), 13(c), 14 or 15(d) of the Exchange Act for so long as
         the delivery of a prospectus is required in connection with the
         offering or sale of such Designated Securities, and during such same
         period to advise the Representatives, promptly after it receives notice
         thereof, of the time when any amendment to the Registration Statement
         has been filed or becomes effective or any supplement to the Prospectus
         or any amended Prospectus has been filed with the Commission, of the
         issuance by the Commission of any stop order or of any order preventing
         or suspending the use of any prospectus relating to the Designated
         Securities, of the suspension of the qualification of such Designated
         Securities for offering or sale in any jurisdiction, of the initiation
         or threatening of any proceeding for any such purpose, or of any
         request by the Commission for the amending or supplementing of the
         Registration Statement or Prospectus or for additional information;
         and, in the event of the issuance of any such



                                       9
<PAGE>


         stop order or of any such order preventing or suspending the use of
         any prospectus relating to the Designated Securities or suspending any
         such qualification, to promptly use its best efforts to obtain the
         withdrawal of such order;

                (b) Promptly from time to time to take such action as the
         Representatives may reasonably request to qualify the Designated
         Securities for offering and sale under the securities laws of such
         jurisdictions as the Representatives may request and to comply with
         such laws so as to permit the continuance of sales and dealings therein
         in such jurisdictions for as long as may be necessary to complete the
         distribution of such Designated Securities, provided that in connection
         therewith the Company shall not be required to qualify as a foreign
         corporation or to file a general consent to service of process in any
         jurisdiction;

                (c) To furnish the Underwriters with copies of the Prospectus as
         amended or supplemented, in such quantities as the Representatives may
         from time to time reasonably request, and, if the delivery of a
         Prospectus is required at any time in connection with the offering or
         sale of the Designated Securities and if at such time any event shall
         have occurred as a result of which the Prospectus as then amended or
         supplemented would include an untrue statement of a material fact or
         omit to state any material fact necessary in order to make the
         statements therein, in the light of the circumstances under which they
         were made when such Prospectus is delivered, not misleading, or, if for
         any other reason it shall be necessary during such same period to amend
         or supplement the Prospectus or to file under the Exchange Act any
         document incorporated by reference in the Prospectus in order to comply
         with the Act, the Exchange Act or the Trust Indenture Act, to notify
         the Representatives and, upon their request, to file such document and
         to prepare and furnish without charge to each Underwriter and to any
         dealer in securities as many copies as the Representatives may from
         time to time reasonably request of an amended Prospectus or a
         supplement to the Prospectus which will correct such statement or
         omission or effect such compliance;

                (d) To cause the Trust to make generally available to holders of
         Designated Securities, as soon as practicable, but in any event not
         later than eighteen months after the effective date of the Registration
         Statement (as defined in Rule 158(c) under the Act), an earnings
         statement of the Trust (which need not be audited) complying with
         Section 11(a) of the Act and the rules and regulations of the
         Commission thereunder (including, at the option of the Company, Rule
         158); and

                (e) To apply the net proceeds of the offering and sale of the
         Designated Securities and the related Certificates that it receives in
         the manner set forth in the Prospectus.

         6. The Company and Sallie Mae covenant and agree with the several
Underwriters that the Company or Sallie Mae will pay or cause to be paid the
following: (i) the fees, disbursements and expenses of the Company's and Sallie
Mae's counsel and accountants in connection with the registration of the
Securities under the Act and all other expenses in



                                       10

connection with the preparation, printing and filing of the Registration
Statement, any Preliminary Prospectus and the Prospectus and amendments and
supplements thereto and the mailing and delivering of copies thereof to the
Underwriters and dealers; (ii) the cost of printing or producing any Agreement
among Underwriters, this Agreement, any Pricing Agreement, any Indenture, any
Trust Agreement, any Delayed Delivery Contracts, any Blue Sky and Legal

any other documents in connection with the offering, purchase, sale and delivery
of the Designated Securities; (iii) all expenses in connection with the

(iv) any fees charged by securities rating services for rating the Designated
Securities; (v) the cost of preparing the Designated Securities; (vi) the fees
and expenses of the Eligible Lender Trustee and the Indenture Trustee and any

however, that, except as provided in this Section, and Sections 8 and 11 hereof,
the Underwriters will pay all of their own costs and expenses, including the
fees of their counsel, transfer taxes on resale of any of the Securities by
them, and any advertising expenses connected with any offers they may make.

         7. The obligations of the Underwriters of any Designated Securities
under the Pricing Agreement relating to such Designated Securities shall be
subject, in the reasonable discretion of the Representatives, to the condition
that all representations and warranties and other statements of the Company and
Sallie Mae in or incorporated by reference in the Pricing Agreement relating to
such Designated Securities are, at and as of the Time of Delivery for such
Designated Securities, true and correct, the condition that the Company and
Sallie Mae shall have performed all of their obligations hereunder theretofore
to be performed, and the following additional conditions:

                (a) The Prospectus as amended or supplemented in relation to the
         applicable Designated Securities shall have been filed with the
         Commission pursuant to Rule 424(b) within the applicable time period
         prescribed for such filing by the rules and regulations under the Act
         and in accordance with Section 5(a) hereof; no stop order suspending
         the effectiveness of the Registration Statement or any part thereof
         shall have been issued and no proceeding for that purpose shall have
         been initiated or threatened by the Commission; and all requests for

         complied with;

                (b) Counsel for the Underwriters shall have furnished
         Representatives such opinion or opinions, substantially in the form
         attached hereto as Annex II(a), dated the



                                       11
<PAGE>


         Time of Delivery for such Designated Securities, with respect to the
         Designated Securities and such other related matters as the
         Representatives may reasonably request;

                (c) Internal counsel for the Company, Sallie Mae and the
         Servicer, satisfactory to the Representatives, shall have furnished to
         the Representatives a written opinion or opinions, dated the Time of
         Delivery for such Designated Securities, substantially in the form
         attached hereto as Annex II(b) or as is otherwise satisfactory to the
         Representatives;

                (d) Special counsel for the Company, Sallie Mae and the
         Servicer, satisfactory to the Representatives, shall have furnished to
         the Representatives a written opinion or opinions, dated the Time of
         Delivery for such Designated Securities, substantially in the form
         attached hereto as Annex II(a) or as is otherwise satisfactory to the
         Representatives;

                (e) Counsel for the Eligible Lender Trustee, satisfactory to the
         Representatives, shall have furnished to the Representatives a written
         opinion or opinions, dated the Time of Delivery for such Designated
         Securities, substantially in the form attached hereto as Annex II(d) or
         as is otherwise satisfactory to the Representatives;

                (f) Counsel for the Indenture Trustee, satisfactory to the
         Representatives, shall have furnished to the Representatives a written
         opinion or opinions, dated the Time of Delivery for such Designated
         Securities, substantially in the form attached hereto as Annex II(e) or
         as is otherwise satisfactory to the Representatives;

                (g) At the time a Preliminary Prospectus relating to such
         Designated Securities was distributed and on the date of the Pricing
         Agreement for such Designated Securities, the independent public
         accountants of the Company and Sallie Mae shall have furnished to the
         Representatives a letter or letters with respect to the Company, Sallie
         Mae, the statistical and financial information contained in the
         Preliminary Prospectus and the Prospectus and certain agreed upon
         procedures with respect to the issuance and offering of the Designated
         Securities and the related Student Loans, in form and substance
         satisfactory to the Representatives and in each case confirming that
         such accountants are independent public accountants with the meaning of
         the Act and the applicable rules and regulations thereunder;

                (h) (i) Neither the Company nor Sallie Mae shall have sustained
         since the date of the financial statements included in Sallie Mae's
         most recently published Information Statement any material loss or
         interference with its business from fire, explosion, flood or other
         calamity, whether or not covered by insurance, or from any labor
         dispute or court or governmental action, order or decree, otherwise
         than as set forth or contemplated in such Information Statement, and
         (ii) since such date, there shall not have been any material adverse
         change in the capital stock or long-term debt of the Company or Sallie
         Mae or any such change, or any development involving a prospective such
         change, in or affecting the general affairs, management, financial
         position, shareholders' equity or results of operations of the Company
         or Sallie Mae



                                       12
<PAGE>


         otherwise than as set forth or contemplated in such Information
         Statement, the effect of which, in any such case described in clause
         (i) or (ii), is in the judgment of the Representatives so material and
         adverse as to make it impracticable or inadvisable to proceed with the
         public offering or the delivery of the Underwriters' Securities on the
         terms and in the manner contemplated in the Prospectus as first
         amended or supplemented relating to the Designated Securities;

                (i) On or after the date of the Pricing Agreement relating to
         the Designated Securities (i) no downgrading shall have occurred in the
         rating accorded Sallie Mae's debt securities or preferred stock by any
         "nationally recognized statistical rating organization", as that term
         is defined by the Commission for purposes of Rule 436(g)(2) under the
         Act ("Rating Agency"), and (ii) no such Rating Agency shall have
         publicly announced that it has under surveillance or review, with
         possible negative implications, its rating of any of Sallie Mae's debt
         securities;

                (j) On or after the date of the Pricing Agreement relating to
         the Designated Securities there shall not have occurred any of the
         following: (i) a suspension or material limitation in trading in
         securities generally on the New York Stock Exchange or any setting of
         minimum prices for trading on such exchange; (ii) a general moratorium
         on commercial banking activities declared by either Federal or New York
         State authorities; or (iii) the outbreak or escalation of hostilities
         involving the United States or the declaration by the United States of
         a national emergency or war, if the effect of any such event specified
         in this clause (iii) in the reasonable judgment of the Representatives
         makes it impracticable or inadvisable to proceed with the public
         offering or the delivery of the Underwriters' Securities on the terms
         and in the manner contemplated in the Prospectus as theretofore amended
         or supplemented relating to the Designated Securities;

                (k) Each of the Company and Sallie Mae shall have furnished or
         caused to be furnished to the Representatives at the Time of Delivery
         for the Designated Securities a certificate or certificates of officers
         of the Company or Sallie Mae, as the case may be, satisfactory to the
         Representatives as to the accuracy of the representations and
         warranties of the Company or Sallie Mae, as the case may be, herein at
         and as of such Time of Delivery, as to the performance by the Company
         or Sallie Mae, as the case may be, of all of their obligations
         hereunder to be performed at or prior to such Time of Delivery, as to
         the matters set forth in subsections (a), (h) and (i) of this Section
         and as to such other matters as the Representatives may reasonably
         request;

                (l) At the Time of Delivery, the aggregate principal amount of
         the Underwriters' Securities as specified in the related Pricing
         Agreement for the Designated Securities shall have been sold by the
         Company to the Underwriters, and the aggregate amount of the related
         Certificates as specified in the related underwriting agreement for
         such Certificates shall have been sold by the Company to the
         underwriters specified in such underwriting agreement; and



                                       13
<PAGE>


                (m) The Designated Securities shall be rated as set forth in the
         related Prospectus by the Rating Agency (or Agencies) specified in such
         Prospectus, and such Rating Agency or Agencies shall not have placed
         the Designated Securities under surveillance or review with negative
         implications.

         8. (a) The Company and Sallie Mae, jointly and severally, will
indemnify and hold harmless each Underwriter against any losses, claims, damages
or liabilities, joint or several, to which such Underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, any preliminary prospectus supplement, the Registration
Statement, the Prospectus as amended or supplemented and any other prospectus
relating to the Designated Securities, or any amendment or supplement thereto,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse each Underwriter for any
legal or other expenses reasonably incurred by such Underwriter in connection
with investigating or defending any such action or claim as such expenses are
incurred; PROVIDED, HOWEVER, that the Company and Sallie Mae shall not be liable
in any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in any Preliminary Prospectus, any
preliminary prospectus supplement, the Registration Statement, the Prospectus as
amended or supplemented and any other prospectus relating to the Securities, or
any such amendment or supplement in reliance upon and in conformity with written
information furnished to the Company or Sallie Mae by any Underwriter of
Designated Securities through the Representatives expressly for use in the
Prospectus as amended or supplemented relating to such Securities.

         (b) Each Underwriter will indemnify and hold harmless the Company and
Sallie Mae against any losses, claims, damages or liabilities to which they may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon an untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Prospectus, any preliminary prospectus supplement,
the Registration Statement, the Prospectus as amended or supplemented and any
other prospectus relating to the Securities, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented and any other prospectus relating to the Designated Securities, or
any such amendment or supplement in reliance upon and in conformity with written
information furnished to the Company or Sallie Mae by such Underwriter through
the Representatives expressly for use therein; and will reimburse the Company
for any legal or other expenses reasonably incurred



                                       14
<PAGE>


by the Company in connection with investigating or defending any such action or
claim as such expenses are incurred.

         (c) Promptly after receipt by an indemnified party under subsection (a)
or (b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise than under such subsection. In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the written consent
of the indemnified party, effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or
claim in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified party is an actual or potential party
to such action or claim) unless such settlement, compromise or judgment (i)
includes an unconditional release of the indemnified party from all liability
arising out of such action or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act, by or on behalf of
any indemnified party.

         (d) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company and Sallie Mae, on the one hand and
the Underwriters of the Designated Securities on the other from the offering of
the Designated Securities to which such loss, claim, damage or liability (or
action in respect thereof) relates. If, however, the allocation provided by the
immediately preceding sentence is not permitted by applicable law or if the
indemnified party failed to give the notice required under subsection (c) above,
then each indemnifying party shall contribute to such amount paid or payable by
such indemnified party in such proportion as is appropriate to reflect not only
such relative benefits but also the relative fault of the Company and Sallie
Mae, on the one hand and the Underwriters of the Designated Securities on the
other in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant



                                       15
<PAGE>


equitable considerations. The relative benefits received by the Company and
Sallie Mae, on the one hand, and such Underwriters on the other shall be deemed
to be in the same proportion as the total net proceeds from such offering
(before deducting expenses) received by the Company and Sallie Mae bear to the
total underwriting discounts and commissions received by such Underwriters. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or Sallie Mae, on the one hand, or such Underwriters on the other and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission. The Company, Sallie Mae and
the Underwriters agree that it would not be just and equitable if contribution
pursuant to this subsection (d) were determined by PRO RATA allocation (even if
the Underwriters were treated as one entity for such purpose) or by any other
method of allocation which does not take account of the equitable considerations
referred to above in this subsection (d). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages or liabilities (or
actions in respect thereof) referred to above in this subsection (d) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this subsection (d), no Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the applicable Designated Securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages which such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The obligations of the Underwriters
of Designated Securities in this subsection (d) to contribute are several in
proportion to their respective underwriting obligations with respect to such
Securities and not joint.

         (e) The obligations of the Company and Sallie Mae under this Section 8
shall be in addition to any liability which the Company and Sallie Mae may
otherwise have and shall extend, upon the same terms and conditions, to each
person, if any, who controls any Underwriter within the meaning of the Act; and
the obligations of the Underwriters under this Section 8 shall be in addition to
any liability which the respective Underwriters may otherwise have and shall
extend, upon the same terms and conditions, to each officer and director of the
Company or Sallie Mae and to each person, if any, who controls the Company or
Sallie Mae within the meaning of the Act.

         9. (a) If any Underwriter shall default in its obligation to purchase
the Underwriters' Securities which it has agreed to purchase under the Pricing
Agreement relating to such Underwriters' Securities, the Representatives may in
their discretion arrange for themselves or another party or other parties to
purchase such Underwriters' Securities on the terms contained herein and
therein. If within thirty-six hours after such default by any Underwriter the
Representatives do not arrange for the purchase of such Underwriters'
Securities, then



                                       16
<PAGE>


the Company shall be entitled to a further period of thirty-six hours within
which to procure another party or other parties satisfactory to the
Representatives to purchase such Underwriters' Securities on such terms. In the
event that, within the respective prescribed period, the Representatives notify
the Company that they have so arranged for the purchase of such Underwriters'
Securities, or the Company notifies the Representatives that it has so arranged
for the purchase of such Underwriters' Securities, the Representatives or the
Company shall have the right to postpone the Time of Delivery for such
Underwriters' Securities for a period of not more than seven days, in order to
effect whatever changes may thereby be made necessary in the Registration
Statement or the Prospectus as amended or supplemented, or in any other
documents or arrangements, and the Company agrees to file promptly any
amendments or supplements to the Registration Statement or the Prospectus which
in the opinion of the Representatives may thereby be made necessary. The term
"Underwriter" as used in this Agreement shall include any person substituted
under this Section with like effect as if such person had originally been a
party to the Pricing Agreement with respect to such Designated Securities.

         (b) If, after giving effect to any arrangements for the purchase of the
Underwriters' Securities of a defaulting Underwriter or Underwriters by the
Representatives and the Company as provided in subsection (a) above, the
aggregate principal amount of such Underwriters' Securities which remains
unpurchased does not exceed one-eleventh of the aggregate principal amount of
the Designated Securities, then the Company shall have the right to require each
non-defaulting Underwriter to purchase the principal amount of Underwriters'
Securities which such Underwriter agreed to purchase under the Pricing Agreement
relating to such Designated Securities and, in addition, to require each
non-defaulting Underwriter to purchase its pro rata share (based on the
principal amount of Designated Securities which such Underwriter agreed to
purchase under such Pricing Agreement) of the Underwriters' Securities of such
defaulting Underwriter or Underwriters for which such arrangements have not been
made; but nothing herein shall relieve a defaulting Underwriter from liability
for its default.

         (c) If, after giving effect to any arrangements for the purchase of the
Underwriters' Securities of a defaulting Underwriter or Underwriters by the
Representatives and the Company as provided in subsection (a) above, the
aggregate principal amount of Underwriters' Securities which remains unpurchased
exceeds one-eleventh of the aggregate principal amount of the Designated
Securities, as referred to in subsection (b) above, or if the Company shall not
exercise the right described in subsection (b) above to require non-defaulting
Underwriters to purchase Underwriters' Securities of a defaulting Underwriter or
Underwriters, then the Pricing Agreement relating to such Designated Securities
shall thereupon terminate, without liability on the part of any non-defaulting
Underwriter or the Company, except for the expenses to be borne by the Company
and the Underwriters as provided in Section 6 hereof and the indemnity and
contribution agreements in Section 8 hereof; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

         10. The respective indemnities, agreements, representations, warranties
and other statements of the Company, Sallie Mae and the several Underwriters, as
set forth in this



                                       17
<PAGE>


Agreement or made by or on behalf of them, respectively, pursuant to this
Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Underwriter or any controlling person of any Underwriter, or the Company
or Sallie Mae or any officer or director or controlling person of the Company or
Sallie Mae, and shall survive delivery of and payment for the Securities.

         11. If any Pricing Agreement shall be terminated pursuant to Section 9
hereof, the Company and Sallie Mae shall not then be under any liability to any
Underwriter with respect to the Designated Securities covered by such Pricing
Agreement except as provided in Sections 6 and 8 hereof; but, if for any other
reason Underwriters' Securities are not delivered by or on behalf of the Company
as provided herein, except for any of the reasons specified in Section 7(j), the
Company and Sallie Mae will reimburse the Underwriters through the
Representatives for all out-of-pocket expenses approved in writing by the
Representatives, including fees and disbursements of counsel, reasonably
incurred by the Underwriters in making preparations for the purchase, sale and
delivery of such Designated Securities, but the Company and Sallie Mae shall
then be under no further liability to any Underwriter with respect to such
Designated Securities except as provided in Sections 6 and 8 hereof.

         12. In all dealings hereunder, the Representatives of the Underwriters
of Designated Securities shall act on behalf of each of such Underwriters, and
the parties hereto shall be entitled to act and rely upon any statement,
request, notice or agreement on behalf of any Underwriter made or given by such
Representatives jointly or by such of the Representatives, if any, as may be
designated for such purpose in the Pricing Agreement.

         All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Representatives as set forth in the
Pricing Agreement; and if to the Company or Sallie Mae shall be delivered or
sent by mail, telex or facsimile transmission to:

at its address set forth in its Underwriters' Questionnaire, or telex
constituting such Questionnaire, which address will be supplied to the Company

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 __________, 199__ (the
"Underwriting Agreement"), between the Company and Sallie Mae, on the one hand,
and _____________ and _________________, on the other hand, that the Company
will cause the trust (the "Trust") formed pursuant to the Trust Agreement dated
as of _______, 199__ between the Company and _______, as trustee (the "Eligible
Lender Trustee"), to issue and sell to the Underwriters named in Schedule I
hereto (the "Underwriters") the Student Loan-Backed Notes (the "Notes")
specified in Schedule II hereto (the "Designated Securities"). The Notes will be
issued and secured pursuant to the Indenture, dated ___________ (the
"Indenture"), between the Trust and _________, as trustee (the "Indenture
Trustee").

         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 shall be deemed to be a representation
or warranty as of the date of the Underwriting Agreement in relation to the
Prospectus (as therein defined), and also a representation and warranty as of
the date of this Pricing Agreement in relation to the Prospectus as amended or
supplemented relating to the Designated Securities which are the subject of this
Pricing Agreement. Each reference to the Representatives herein and in the
provisions of the Underwriting Agreement so incorporated by reference shall be
deemed to refer to you. Unless otherwise defined herein, terms defined in 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.




<PAGE>


         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 principal amount of Designated Securities set forth
opposite the name of such Underwriter in Schedule I hereto, less the principal
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 [Closing Date], 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)
collateralized by, or any securities (other than the related Certificates)
evidencing an ownership in, 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 Services Act 1986
(Investment Advertisements) (Exemptions) Order 1995 or is a person to whom such
document may otherwise lawfully be issued or passed on.

         If the foregoing is in accordance with your understanding, please sign
and return to us ______ 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
the signers thereof.

                                          Very truly yours,

MORGAN STANLEY & CO. INCORPORATED
1585 BROADWAY
NEW YORK, NEW YORK  10036

Ladies and Gentlemen:

         From time to time the Student Loan Marketing Association ("Sallie
Mae"), a corporation formed under the laws of the United States, and SLM Funding
Corporation, a Delaware corporation and a wholly-owned subsidiary of Sallie Mae
(the "Company"), propose to enter into one or more Pricing Agreements (each a
"Pricing Agreement") in the form of Annex I hereto, with such additions and
deletions as the parties thereto may determine. Subject to the terms and
conditions stated herein and therein, the Company proposes to cause the Trust
specified in the applicable Pricing Agreement to issue and sell to the firms
named in Schedule I to the applicable Pricing Agreement (such firms constituting
the "Underwriters" with respect to such Pricing Agreement and the securities
specified therein) certain of such Trust's Student Loan-Backed Certificates (the
"Certificates") specified in Schedule II to such Pricing Agreement (with respect
to such Pricing Agreement, the "Designated Securities"), less the amount of
Designated Securities covered by Delayed Delivery Contracts, if any, as provided
in Section 3 hereof and as may be specified in Schedule II to such Pricing
Agreement (with respect to such Pricing Agreement, any Designated Securities to
be covered by Delayed Delivery Contracts are herein sometimes referred to as
"Contract Securities" and the Designated Securities to be purchased by the
Underwriters (after giving effect to the deduction, if any, for Contract
Securities) are herein sometimes referred to as "Underwriters' Securities").

         The Securities may be sold from time to time in one or more Series.
Each Series of Securities, which will include one or more classes of
Certificates and one or more classes of Student Loan-Backed Notes (the "Notes,"
and, together with the Certificates, the "Securities") will be issued by a Trust
to be formed with respect to such Series (each, a "Trust"). Each Trust will be
formed pursuant to a trust agreement (a "Trust Agreement") to be entered into
between the Company and the Eligible Lender Trustee specified in the related
Pricing Agreement (the "Eligible Lender Trustee"). The Notes of each Series will
be issued and secured pursuant to an indenture (an "Indenture") between the
Trust and the Indenture Trustee


<PAGE>

specified in the related Pricing Agreement (the "Indenture Trustee"). The
Certificates of a Series will be issued pursuant to the related Trust Agreement
and will represent fractional undivided interests in the Trust created thereby.
The property of each Trust will include, among other things, educational student
loans to students and/or parents of dependent students ("Student Loans").

         With respect to each Trust, (i) the Company will acquire the related
Student Loans from Sallie Mae pursuant to a Purchase Agreement and (ii) the
Company will sell the related Student Loans to such Trust pursuant to a Sale
Agreement, with the related Eligible Lender Trustee holding legal title thereto.
With respect to each Series, Sallie Mae Servicing Corporation, as servicer (the
"Servicer") will enter into a servicing agreement (a "Servicing Agreement") with
the Trust, the Administrator, the Eligible Lender Trustee and the Indenture
Trustee with respect to the related Student Loans. Sallie Mae, as administrator
(in such capacity, the "Administrator"), has entered into a Master
Administration Agreement with the Company dated as of May 1, 1997 and, as
contemplated by the terms of the Master Administration Agreement, will enter
into an Administration Agreement Supplement among the Company, the Trust, the
Eligible Lender Trustee, the Servicer and the Indenture Trustee with respect to
the Student Loans to be held by the Trust (the Master Administration Agreement,
as supplemented by the Administration Agreement Supplement, the "Administration
Agreement").

         The terms and conditions of any particular issuance of Designated
Securities shall be as specified in the Pricing Agreement relating thereto and
in or pursuant to the related Indenture.

         Capitalized terms used but not defined herein or in any Pricing
Agreement shall have the meanings ascribed thereto in the related Indenture.

         1. Particular sales of Designated Securities may be made from time to
time to the Underwriters of such Securities, for whom the firms designated as
representatives of the Underwriters of such Securities in the Pricing Agreement
relating thereto will act as representatives (the "Representatives"). The term
"Representatives" also refers to a single firm acting as sole representative of
the Underwriters and to an Underwriter or Underwriters who act without any firm
being designated as its or their representatives. This Underwriting Agreement
shall not be construed as an obligation of the Company to sell any of the
Securities or as an obligation of any of the Underwriters to purchase the
Securities. The obligation of the Company to issue and sell any of the
Securities and the obligation of any of the Underwriters to purchase any of the
Securities shall be evidenced by the Pricing Agreement with respect to the
Designated Securities specified therein. Each Pricing Agreement shall specify

of this Section 2 with respect to Sallie Mae or the Servicer constitute
representations, warranties and agreements of Sallie Mae only and not of the
Company) :

                (a) A registration statement on Form S-3 (File No. 333-44465),
         including a form of prospectus, in respect of the Securities has been

         form; no other document with respect to such registration statement or
         document incorporated by reference therein has heretofore been filed or

         Commission under the Securities Act of 1933, as amended (the "Act"),
         each in the form heretofore delivered to the Representatives); and no
         stop order suspending the effectiveness of such registration statement
         has been issued and no proceeding for that purpose has been initiated
         or, to the best of Sallie Mae's or the Company's knowledge, threatened
         by the Commission (any preliminary prospectus included in such
         registration statement or filed with the Commission pursuant to Rule
         424(a) under the Act, is hereinafter called a "Preliminary Prospectus;"
         the various parts of such registration statement, including all
         exhibits thereto and the documents incorporated by reference in the
         prospectus contained in the registration statement at the time such
         part of the registration statement became effective but excluding Form
         T-1, each as amended at the time such part of the registration
         statement became effective, are hereinafter collectively called the

         and include the documents incorporated by reference therein pursuant to
         the applicable form under the Act, as of the date of such Preliminary
         Prospectus or

         Statement; and any reference to the Prospectus as amended or
         supplemented shall be deemed to refer to the Prospectus as amended or
         supplemented in relation to the applicable Designated Securities in the

         under the Act in accordance with Section 5(a) hereof, including any
         documents incorporated by reference therein as of the date of such
         filing);

                (b) The documents incorporated by reference in the Prospectus,
         when they became effective or were filed with the Commission, as the
         case may be, conformed in all material respects to the requirements of
         the Act, the Exchange Act and the Trust Indenture Act of 1939, as
         amended (the "Trust Indenture Act"), as applicable, and the rules and
         regulations of the Commission thereunder, and none of such documents
         contained an untrue statement of a material fact or omitted to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading; and any further documents so filed

         misleading; PROVIDED, HOWEVER, that this representation and warranty
         shall not apply to any statements or omissions made in reliance upon
         and in conformity with information furnished in writing to the Company

         to such Designated Securities;

                (c) The Registration Statement and the Prospectus conform, and
         any further amendments or supplements to the Registration Statement or
         the Prospectus will conform, in all material respects to the
         requirements of the Act and the Trust Indenture Act, as applicable, and
         the rules and regulations of the Commission thereunder and do not and
         will not, as of the applicable effective date as to the Registration
         Statement and any amendment thereto and as of the applicable filing
         date as to the Prospectus and any amendment or supplement thereto,
         contain an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the

         statements therein not misleading; PROVIDED, HOWEVER, that this
         representation and warranty shall not apply to any statements or
         omissions made in reliance upon and in conformity with information
         furnished in writing to the Company by an Underwriter of Designated
         Securities through the Representatives expressly for use in the
         Prospectus as amended or supplemented relating to such Designated
         Securities;

                (d) Neither the Company nor Sallie Mae or any of its
         subsidiaries has sustained since the date of the financial statements
         included in Sallie Mae's most recently published Information Statement
         any material loss or interference with its business from fire,

         insurance, or from any labor dispute or court or governmental action,
         order or decree, otherwise than as set forth or contemplated in such
         Information Statement; and, since such date, there has not been any
         material adverse change in the capital stock or long-term debt of the
         Company or Sallie Mae or any of its subsidiaries or any material
         adverse change, or any development involving a prospective material
         adverse change, in or affecting the general affairs, management,
         financial position, shareholders' equity or results of operations of
         the Company or Sallie Mae or any of its subsidiaries or the
         transactions contemplated hereby, otherwise than as set forth or
         contemplated in such Information Statement;

                (e) The Company has been duly incorporated and is validly
         existing as a corporation in good standing under the laws of the state
         of Delaware, with power and authority (corporate and other) to own its
         properties and conduct its business as described in the Prospectus and
         to consummate the transactions contemplated therein and herein, and is

         non-assessable and are owned beneficially and of record by Sallie Mae;

                (g) This Agreement has been, and each Pricing Agreement with
         respect to the Designated Securities upon its execution and delivery by
         the Company and Sallie Mae will have been, duly authorized, executed
         and delivered by the Company and Sallie Mae. The Securities have been
         duly authorized, and, when Designated Securities are issued and
         delivered pursuant to this Agreement and the Pricing Agreement with
         respect to such Designated Securities, and, in the case of any Contract
         Securities,

         pursuant to Delayed Delivery Contracts with respect to such Contract
         Securities, such Designated Securities and Contract Securities will
         have been duly executed, authenticated, issued and delivered. The
         related Notes will constitute valid and legally binding obligations of
         the related Trust entitled to the benefits provided by the Indenture,
         which will be substantially in the form filed as an exhibit to the
         Registration Statement. The Indenture has been duly authorized and duly
         qualified under the Trust Indenture Act. The Designated Securities are
         intended to represent undivided ownership interests in the Trust
         created by the Trust Agreement, which will be substantially in the form
         filed as an exhibit to the Registration Statement, and will be entitled
         to the benefits provided by the Trust Agreement. At the Time of
         Delivery (as defined in Section 4 hereof) for the Designated
         Securities, the Indenture and the Trust Agreement will each constitute
         a valid and legally binding instrument, enforceable in accordance with
         its terms, subject, as to enforcement, to bankruptcy, insolvency,
         reorganization and other laws of general applicability relating to or
         affecting creditors' rights and to general equity principles. The
         Indenture and Trust Agreement conform, and the Designated Securities
         and the related Notes will conform, to the descriptions thereof
         contained in the Prospectus as amended or supplemented with respect to
         the Designated Securities;

                (h) The issue and sale of the Securities and the compliance by
         the Company with all of the provisions of the Securities, the
         Indenture, the Trust Agreement, each of the Delayed Delivery Contracts,
         this Agreement and any Pricing Agreement, and the consummation of the
         transactions herein and therein contemplated will not conflict with or
         result in a breach or violation of any of the terms or provisions of,
         or constitute a default under, any indenture, mortgage, deed of trust,
         loan agreement or other agreement or instrument to which the Company or
         Sallie Mae is a party or by which the Company or Sallie Mae is bound or
         to which any of the property or assets of the Company or Sallie Mae is
         subject, nor will such action result in any violation of the provisions
         of the Company's Certificate of Incorporation or By-laws, Sallie Mae's
         charter, enabling legislation or By-laws, or any statute or any order,
         rule or regulation of any court or governmental agency or body having
         jurisdiction over the Company or Sallie Mae or any of their properties;
         and no consent, approval, authorization, order, registration or
         qualification of or with any such court or governmental agency or body
         is required for the issue and sale of the Securities or the
         consummation by the Company or Sallie Mae of the transactions
         contemplated by this Agreement or any Pricing Agreement or the
         Indenture or any Delayed Delivery Contract, except such as have been,
         or will have been prior to the Time of Delivery, obtained under the Act
         and the Trust Indenture Act and such consents, approvals,
         authorizations, registrations or qualifications as may be required
         under state securities or Blue Sky laws in connection with the purchase
         and distribution of the Designated Securities by the Underwriters;

                (i) The statements set forth in the Prospectus under the
         captions "Description of the Notes" and "Description of the
         Certificates" and set forth in the Prospectus



                                       6

         Supplement under the caption "Description of the Securities," insofar
         as they purport to constitute a summary of the terms of the Notes and
         the Certificates, are accurate, complete and fair;

                (j) Sallie Mae is not in violation of its charter as set forth
         in its enabling legislation or By-laws, and the Company is not in
         violation of its Certificate of Incorporation or By-laws, and neither
         Sallie Mae nor the Company is in default in the performance or
         observance of any material obligation, agreement, covenant or condition
         contained in any indenture, mortgage, deed of trust, loan agreement,
         lease or other agreement or instrument to which it is a party or by
         which it or any of its properties may be bound;

                (k) Other than as set forth in the Prospectus or in Sallie Mae's
         most recently published Information Statement, there are no legal or
         governmental proceedings pending to which the Company or Sallie Mae or
         any of its subsidiaries is a party or of which any property of the
         Company or Sallie Mae or any of its subsidiaries is the subject which,
         if determined adversely to the Company or Sallie Mae or any of its
         subsidiaries, would individually or in the aggregate have a material
         adverse effect on the current or future consolidated financial
         position, shareholders' equity or results of operations of the Company
         or Sallie Mae or any of its subsidiaries or on the consummation of the
         transactions contemplated hereby; and, to the best of the Company's and
         Sallie Mae's knowledge, no such proceedings are threatened or
         contemplated by governmental authorities or threatened by others;

                (l) The Company is not and, after giving effect to the offering
         and sale of the Securities, will not be an "investment company" or an
         entity "controlled" by an "investment company", as such terms are
         defined in the Investment Company Act of 1940, as amended (the
         "Investment Company Act");

                (m) Neither the Company, Sallie Mae nor any of their affiliates
         does business with the government of Cuba or with any person or
         affiliate located in Cuba within the meaning of Section 517.075,
         Florida Statutes;

                (n) Arthur Anderson LLP are independent public accountants as
         required by the Act and the rules and regulations of the Commission
         thereunder;

                (o) At the Time of Delivery of the Designated Securities, Sallie
         Mae's representations and warranties in the related Purchase Agreement
         and the Administration Agreement, the Company's representations and
         warranties in the related Sale Agreement and Trust Agreement and the
         Servicer's representations and warranties in the Servicing Agreement
         will be true and correct in all material respects; and

                (p) In the event any of the Securities are purchased pursuant to
         Delayed Delivery Contracts, each of such Delayed Delivery Contracts has
         been duly authorized by the Company and Sallie Mae and, when executed
         and delivered by the Company and the purchaser named therein, will
         constitute a valid and legally binding agreement of



                                       7
<PAGE>

         the Company enforceable in accordance with its terms, subject, as to
         enforcement, to bankruptcy, insolvency, reorganization and other laws
         of general applicability relating to or affecting creditors' rights and
         to general equity principles; and any Delayed Delivery Contracts
         conform to the description thereof in the Prospectus.

         3. Upon the execution of the Pricing Agreement applicable to any
Designated Securities and authorization by the Representatives of the release of
the Underwriters' Securities, the several Underwriters propose to offer such
Underwriters' Securities for sale upon the terms and conditions set forth in the
Prospectus as amended or supplemented.

         The Company may specify in Schedule II to the Pricing Agreement
applicable to any Designated Securities that the Underwriters are authorized to
solicit offers to purchase Designated Securities from the Company pursuant to
delayed delivery contracts (herein called "Delayed Delivery Contracts"),
substantially in the form of Annex III attached hereto but with such changes
therein as the Representatives and the Company may authorize or approve. If so
specified, the Underwriters will endeavor to make such arrangements, and as
compensation therefor the Company will pay to the Representatives, for the
accounts of the Underwriters, at the Time of Delivery, such commission, if any,
as may be set forth in such Pricing Agreement. Delayed Delivery Contracts, if
any, are to be with investors of the types described in the Prospectus and
subject to other conditions therein set forth. The Underwriters will not have
any responsibility with respect to the validity or performance of any Delayed
Delivery Contracts.

         The amount of Contract Securities to be deducted from the amount of
Designated Securities to be purchased by each Underwriter as set forth in
Schedule I to the Pricing Agreement applicable to such Designated Securities
shall be, in each case, the amount of Contract Securities which the Company has
been advised by the Representatives have been attributed to such Underwriter,
provided that, if the Company has not been so advised, the amount of Contract
Securities to be so deducted shall be, in each case, that proportion of Contract
Securities which the amount of Designated Securities to be purchased by such
Underwriter under such Pricing Agreement bears to the total amount of the
Designated Securities (rounded as the Representatives may determine). The total
amount of Underwriters' Securities to be purchased by all the Underwriters
pursuant to such Pricing Agreement shall be the total amount of Designated
Securities set forth in Schedule I to such Pricing Agreement less the amount of
the Contract Securities. The Company will deliver to the Representatives not
later than 3:30 p.m., New York City time, on the third business day preceding
the Time of Delivery specified in the applicable Pricing Agreement (or such
other time and date as the Representatives and the Company may agree upon in
writing), a written notice setting forth the amount of Contract Securities.

         4. Underwriters' Securities to be purchased by each Underwriter
pursuant to the Pricing Agreement relating thereto, in the form specified in
such Pricing Agreement, and in such authorized denominations and registered in
such names as the Representatives may request upon at least forty-eight hours'
prior notice to the Company, shall be delivered by or



                                       8
<PAGE>

on behalf of the Company to the Representatives for the account of such
Underwriter, against payment by such Underwriter or on its behalf of the
purchase price therefor by wire transfer or by certified or official bank check
or checks, payable to the order of the Company in the funds specified in such
Pricing Agreement, all in the manner and at the place and time and date
specified in such Pricing Agreement or at such other place and time and date as
the Representatives and the Company may agree upon in writing, such time and
date being herein called the "Time of Delivery" for such Securities.

         Concurrently with the delivery of and payment for the Underwriters'
Securities, the Company will deliver to the Representatives for the accounts of
the Underwriters a check payable to the order of the party designated in the
Pricing Agreement relating to such Underwriters' Securities in the amount of any
compensation payable by the Company to the Underwriters in respect of any
Delayed Delivery Contracts as provided in Section 3 hereof and the Pricing
Agreement relating to such Securities.

         5. The Company agrees with each of the Underwriters of any Designated
Securities, and Sallie Mae agrees with such Underwriters that it will cause the
Company:

                (a) To prepare the Prospectus as amended or supplemented in
         relation to the applicable Designated Securities in a form approved by
         the Representatives and to file such Prospectus pursuant to Rule 424(b)
         under the Act not later than the Commission's close of business on the
         second business day following the execution and delivery of the Pricing
         Agreement relating to the applicable Designated Securities or, if
         applicable, such earlier time as may be required by Rule 424(b); to
         make no further amendment or any supplement to the Registration
         Statement or Prospectus as amended or supplemented after the date of
         the Pricing Agreement relating to such Designated Securities and prior
         to the Time of Delivery for such Designated Securities which shall be
         disapproved by the Representatives for such Designated Securities
         promptly after reasonable notice thereof; to advise the Representatives
         promptly of any such amendment or supplement after such Time of
         Delivery and furnish the Representatives with copies thereof; to file
         promptly all reports and any definitive proxy or information statements
         required to be filed by the Company with the Commission pursuant to
         Section 13(a), 13(c), 14 or 15(d) of the Exchange Act for so long as
         the delivery of a prospectus is required in connection with the
         offering or sale of such Designated Securities, and during such same
         period to advise the Representatives, promptly after it receives notice
         thereof, of the time when any amendment to the Registration Statement
         has been filed or becomes effective or any supplement to the Prospectus
         or any amended Prospectus has been filed with the Commission, of the
         issuance by the Commission of any stop order or of any order preventing
         or suspending the use of any prospectus relating to the Designated
         Securities, of the suspension of the qualification of such Designated
         Securities for offering or sale in any jurisdiction, of the initiation
         or threatening of any proceeding for any such purpose, or of any
         request by the Commission for the amending or supplementing of the
         Registration Statement or Prospectus or for additional information;
         and, in the event of the issuance of any such



                                       9
<PAGE>

         stop order or of any such order preventing or suspending the use of any
         prospectus relating to the Designated Securities or suspending any such
         qualification, to promptly use its best efforts to obtain the
         withdrawal of such order;

                (b) Promptly from time to time to take such action as the
         Representatives may reasonably request to qualify the Designated
         Securities for offering and sale under the securities laws of such
         jurisdictions as the Representatives may request and to comply with
         such laws so as to permit the continuance of sales and dealings therein
         in such jurisdictions for as long as may be necessary to complete the
         distribution of such Designated Securities, provided that in connection
         therewith the Company shall not be required to qualify as a foreign
         corporation or to file a general consent to service of process in any
         jurisdiction;

                (c) To furnish the Underwriters with copies of the Prospectus as
         amended or supplemented, in such quantities as the Representatives may
         from time to time reasonably request, and, if the delivery of a
         Prospectus is required at any time in connection with the offering or
         sale of the Designated Securities and if at such time any event shall
         have occurred as a result of which the Prospectus as then amended or
         supplemented would include an untrue statement of a material fact or
         omit to state any material fact necessary in order to make the
         statements therein, in the light of the circumstances under which they
         were made when such Prospectus is delivered, not misleading, or, if for
         any other reason it shall be necessary during such same period to amend
         or supplement the Prospectus or to file under the Exchange Act any
         document incorporated by reference in the Prospectus in order to comply
         with the Act, the Exchange Act or the Trust Indenture Act, to notify
         the Representatives and, upon their request, to file such document and
         to prepare and furnish without charge to each Underwriter and to any
         dealer in securities as many copies as the Representatives may from
         time to time reasonably request of an amended Prospectus or a
         supplement to the Prospectus which will correct such statement or
         omission or effect such compliance;

                (d) To cause the Trust to make generally available to holders of
         Designated Securities, as soon as practicable, but in any event not
         later than eighteen months after the effective date of the Registration
         Statement (as defined in Rule 158(c) under the Act), an earnings
         statement of the Trust (which need not be audited) complying with
         Section 11(a) of the Act and the rules and regulations of the
         Commission thereunder (including, at the option of the Company, Rule
         158); and

                (e) To apply the net proceeds of the offering and sale of the
         Designated Securities and the related Notes that it receives in the
         manner set forth in the Prospectus.

         6. The Company and Sallie Mae covenant and agree with the several
Underwriters that the Company or Sallie Mae will pay or cause to be paid the
following: (i) the fees, disbursements and expenses of the Company's and Sallie
Mae's counsel and accountants in connection with the registration of the
Securities under the Act and all other expenses in



                                       10

connection with the preparation, printing and filing of the Registration
Statement, any Preliminary Prospectus and the Prospectus and amendments and

among Underwriters, this Agreement, any Pricing Agreement, any Indenture, any

any other documents in connection with the offering, purchase, sale and delivery
of the Designated Securities; (iii) all expenses in connection with the

(iv) any fees charged by securities rating services for rating the Designated
Securities; (v) the cost of preparing the Designated Securities; (vi) the fees
and expenses of the Eligible Lender Trustee and the Indenture Trustee and any
agent of the Eligible Lender Trustee or the Indenture Trustee and the fees and

the Underwriters will pay all of their own costs and expenses, including the
fees of their counsel, transfer taxes on resale of any of the Securities by

         7. The obligations of the Underwriters of any Designated Securities
under the Pricing Agreement relating to such Designated Securities shall be
subject, in the reasonable discretion of the Representatives, to the condition
that all representations and warranties and other statements of the Company and
Sallie Mae in or incorporated by reference in the Pricing Agreement relating to
such Designated Securities are, at and as of the Time of Delivery for such
Designated Securities, true and correct, the condition that the Company and
Sallie Mae shall have performed all of their obligations hereunder theretofore
to be performed, and the following additional conditions:

                (a) The Prospectus as amended or supplemented in relation to the
         applicable Designated Securities shall have been filed with the

         prescribed for such filing by the rules and regulations under the Act
         and in accordance with Section 5(a) hereof; no stop order suspending
         the effectiveness of the Registration Statement or any part thereof
         shall have been issued and no proceeding for that purpose shall have

                (b) Counsel for the Underwriters shall have furnished

                                       11
<PAGE>

         Time of Delivery for such Designated Securities, with respect to the
         Designated Securities and such other related matters as the
         Representatives may reasonably request;

                (c) Internal counsel for the Company, Sallie Mae and the
         Servicer, satisfactory to the Representatives, shall have furnished to
         the Representatives a written opinion or opinions, dated the Time of
         Delivery for such Designated Securities, substantially in the form
         attached hereto as Annex II(b) or as is otherwise satisfactory to the
         Representatives;

                (d) Special counsel for the Company, Sallie Mae and the
         Servicer, satisfactory to the Representatives, shall have furnished to
         the Representatives a written opinion or opinions, dated the Time of
         Delivery for such Designated Securities, substantially in the form
         attached hereto as Annex II(a) or as is otherwise satisfactory to the
         Representatives;

                (e) Counsel for the Eligible Lender Trustee, satisfactory to the
         Representatives, shall have furnished to the Representatives a written
         opinion or opinions, dated the Time of Delivery for such Designated
         Securities, substantially in the form attached hereto as Annex II(c) or
         as is otherwise satisfactory to the Representatives;

                (f) Counsel for the Indenture Trustee, satisfactory to the
         Representatives, shall have furnished to the Representatives a written
         opinion or opinions, dated the Time of Delivery for such Designated
         Securities, substantially in the form attached hereto as Annex II(d) or
         as is otherwise satisfactory to the Representatives;

                (g) At the time a Preliminary Prospectus relating to such
         Designated Securities was distributed and on the date of the Pricing
         Agreement for such Designated Securities, the independent public
         accountants of the Company and Sallie Mae shall have furnished to the
         Representatives a letter or letters with respect to the Company, Sallie
         Mae, the statistical and financial information contained in the
         Preliminary Prospectus and the Prospectus, as the case may be, and
         certain agreed upon procedures with respect to the issuance and
         offering of the Designated Securities and the related Student Loans, in
         form and substance satisfactory to the Representatives and in each case
         confirming that such accountants are independent public accountants
         with the meaning of the Act and the applicable rules and regulations
         thereunder;

                (h) (i) Neither the Company nor Sallie Mae shall have sustained
         since the date of the financial statements included in Sallie Mae's
         most recently published Information Statement any material loss or
         interference with its business from fire, explosion, flood or other
         calamity, whether or not covered by insurance, or from any labor
         dispute or court or governmental action, order or decree, otherwise
         than as set forth or contemplated in such Information Statement, and
         (ii) since such date, there shall not have been any material adverse
         change in the capital stock or long-term debt of the Company or Sallie
         Mae or any such change, or any development involving a prospective such
         change, in or affecting the general affairs, management, financial
         position, shareholders' equity or results of operations of the Company
         or Sallie Mae



                                       12
<PAGE>

         otherwise than as set forth or contemplated in such Information
         Statement, the effect of which, in any such case described in clause
         (i) or (ii), is in the judgment of the Representatives so material and
         adverse as to make it impracticable or inadvisable to proceed with the
         public offering or the delivery of the Underwriters' Securities on the
         terms and in the manner contemplated in the Prospectus as first amended
         or supplemented relating to the Designated Securities;

                (i) On or after the date of the Pricing Agreement relating to
         the Designated Securities (i) no downgrading shall have occurred in the
         rating accorded Sallie Mae's debt securities or preferred stock by any
         "nationally recognized statistical rating organization", as that term
         is defined by the Commission for purposes of Rule 436(g)(2) under the
         Act ("Rating Agency"), and (ii) no such Rating Agency shall have
         publicly announced that it has under surveillance or review, with
         possible negative implications, its rating of any of Sallie Mae's debt
         securities;

                (j) On or after the date of the Pricing Agreement relating to
         the Designated Securities there shall not have occurred any of the
         following: (i) a suspension or material limitation in trading in
         securities generally on the New York Stock Exchange or any setting of
         minimum prices for trading on such exchange; (ii) a general moratorium
         on commercial banking activities declared by either Federal or New York
         State authorities; or (iii) the outbreak or escalation of hostilities
         involving the United States or the declaration by the United States of
         a national emergency or war, if the effect of any such event specified
         in this clause (iii) in the reasonable judgment of the Representatives
         makes it impracticable or inadvisable to proceed with the public
         offering or the delivery of the Underwriters' Securities on the terms
         and in the manner contemplated in the Prospectus as theretofore amended
         or supplemented relating to the Designated Securities;

                (k) Each of the Company and Sallie Mae shall have furnished or
         caused to be furnished to the Representatives at the Time of Delivery
         for the Designated Securities a certificate or certificates of officers
         of the Company or Sallie Mae, as the case may be, satisfactory to the
         Representatives as to the accuracy of the representations and
         warranties of the Company or Sallie Mae, as the case may be, herein at
         and as of such Time of Delivery, as to the performance by the Company
         or Sallie Mae, as the case may be, of all of their obligations
         hereunder to be performed at or prior to such Time of Delivery, as to
         the matters set forth in subsections (a), (h) and (i) of this Section
         and as to such other matters as the Representatives may reasonably
         request;

                (l) At the Time of Delivery, the aggregate amount of the
         Underwriters' Securities as specified in the related Pricing Agreement
         for the Designated Securities shall have been sold by the Company to
         the Underwriters, and the aggregate principal amount of the related
         Notes as specified in the related underwriting agreement for such Notes
         shall have been sold by the Company to the underwriters specified in
         such underwriting agreement; and



                                       13
<PAGE>

                (m) The Designated Securities shall be rated as set forth in the
         related Prospectus by the Rating Agency (or Agencies) specified in such
         Prospectus, and such Rating Agency or Agencies shall not have placed
         the Designated Securities under surveillance or review with negative
         implications.

         8. (a) The Company and Sallie Mae, jointly and severally, will
indemnify and hold harmless each Underwriter against any losses, claims, damages
or liabilities, joint or several, to which such Underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, any preliminary prospectus supplement, the Registration
Statement, the Prospectus as amended or supplemented and any other prospectus
relating to the Designated Securities, or any amendment or supplement thereto,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse each Underwriter for any
legal or other expenses reasonably incurred by such Underwriter in connection
with investigating or defending any such action or claim as such expenses are
incurred; PROVIDED, HOWEVER, that the Company and Sallie Mae shall not be liable
in any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in any Preliminary Prospectus, any
preliminary prospectus supplement, the Registration Statement, the Prospectus as
amended or supplemented and any other prospectus relating to the Securities, or
any such amendment or supplement in reliance upon and in conformity with written
information furnished to the Company or Sallie Mae by any Underwriter of
Designated Securities through the Representatives expressly for use in the
Prospectus as amended or supplemented relating to such Securities.

         (b) Each Underwriter will indemnify and hold harmless the Company and
Sallie Mae against any losses, claims, damages or liabilities to which they may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon an untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Prospectus, any preliminary prospectus supplement,
the Registration Statement, the Prospectus as amended or supplemented and any
other prospectus relating to the Securities, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented and any other prospectus relating to the Designated Securities, or
any such amendment or supplement in reliance upon and in conformity with written
information furnished to the Company or Sallie Mae by such Underwriter through
the Representatives expressly for use therein; and will reimburse the Company
for any legal or other expenses reasonably incurred



                                       14
<PAGE>

by the Company in connection with investigating or defending any such action or
claim as such expenses are incurred.

         (c) Promptly after receipt by an indemnified party under subsection (a)
or (b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise than under such subsection. In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the written consent
of the indemnified party, effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or
claim in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified party is an actual or potential party
to such action or claim) unless such settlement, compromise or judgment (i)
includes an unconditional release of the indemnified party from all liability
arising out of such action or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act, by or on behalf of
any indemnified party.

         (d) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company and Sallie Mae, on the one hand and
the Underwriters of the Designated Securities on the other from the offering of
the Designated Securities to which such loss, claim, damage or liability (or
action in respect thereof) relates. If, however, the allocation provided by the
immediately preceding sentence is not permitted by applicable law or if the
indemnified party failed to give the notice required under subsection (c) above,
then each indemnifying party shall contribute to such amount paid or payable by
such indemnified party in such proportion as is appropriate to reflect not only
such relative benefits but also the relative fault of the Company and Sallie
Mae, on the one hand and the Underwriters of the Designated Securities on the
other in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant



                                       15
<PAGE>

equitable considerations. The relative benefits received by the Company and
Sallie Mae, on the one hand, and such Underwriters on the other shall be deemed
to be in the same proportion as the total net proceeds from such offering
(before deducting expenses) received by the Company and Sallie Mae bear to the
total underwriting discounts and commissions received by such Underwriters. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or Sallie Mae, on the one hand, or such Underwriters on the other and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission. The Company, Sallie Mae and
the Underwriters agree that it would not be just and equitable if contribution
pursuant to this subsection (d) were determined by PRO RATA allocation (even if
the Underwriters were treated as one entity for such purpose) or by any other
method of allocation which does not take account of the equitable considerations
referred to above in this subsection (d). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages or liabilities (or
actions in respect thereof) referred to above in this subsection (d) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this subsection (d), no Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the applicable Designated Securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages which such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The obligations of the Underwriters
of Designated Securities in this subsection (d) to contribute are several in
proportion to their respective underwriting obligations with respect to such
Securities and not joint.

         (e) The obligations of the Company and Sallie Mae under this Section 8
shall be in addition to any liability which the Company and Sallie Mae may
otherwise have and shall extend, upon the same terms and conditions, to each
person, if any, who controls any Underwriter within the meaning of the Act; and
the obligations of the Underwriters under this Section 8 shall be in addition to
any liability which the respective Underwriters may otherwise have and shall
extend, upon the same terms and conditions, to each officer and director of the
Company or Sallie Mae and to each person, if any, who controls the Company or
Sallie Mae within the meaning of the Act.

         9. (a) If any Underwriter shall default in its obligation to purchase
the Underwriters' Securities which it has agreed to purchase under the Pricing
Agreement relating to such Underwriters' Securities, the Representatives may in
their discretion arrange for themselves or another party or other parties to
purchase such Underwriters' Securities on the terms contained herein and
therein. If within thirty-six hours after such default by any Underwriter the
Representatives do not arrange for the purchase of such Underwriters'
Securities, then the



                                       16
<PAGE>

Company shall be entitled to a further period of thirty-six hours within which
to procure another party or other parties satisfactory to the Representatives to
purchase such Underwriters' Securities on such terms. In the event that, within
the respective prescribed period, the Representatives notify the Company that
they have so arranged for the purchase of such Underwriters' Securities, or the
Company notifies the Representatives that it has so arranged for the purchase of
such Underwriters' Securities, the Representatives or the Company shall have the
right to postpone the Time of Delivery for such Underwriters' Securities for a
period of not more than seven days, in order to effect whatever changes may
thereby be made necessary in the Registration Statement or the Prospectus as
amended or supplemented, or in any other documents or arrangements, and the
Company agrees to file promptly any amendments or supplements to the
Registration Statement or the Prospectus which in the opinion of the
Representatives may thereby be made necessary. The term "Underwriter" as used in
this Agreement shall include any person substituted under this Section with like
effect as if such person had originally been a party to the Pricing Agreement
with respect to such Designated Securities.

         (b) If, after giving effect to any arrangements for the purchase of the
Underwriters' Securities of a defaulting Underwriter or Underwriters by the
Representatives and the Company as provided in subsection (a) above, the
aggregate amount of such Underwriters' Securities which remains unpurchased does
not exceed one-eleventh of the aggregate amount of the Designated Securities,
then the Company shall have the right to require each non-defaulting Underwriter
to purchase the amount of Underwriters' Securities which such Underwriter agreed
to purchase under the Pricing Agreement relating to such Designated Securities
and, in addition, to require each non-defaulting Underwriter to purchase its pro
rata share (based on the amount of Designated Securities which such Underwriter
agreed to purchase under such Pricing Agreement) of the Underwriters' Securities
of such defaulting Underwriter or Underwriters for which such arrangements have
not been made; but nothing herein shall relieve a defaulting Underwriter from
liability for its default.

         (c) If, after giving effect to any arrangements for the purchase of the
Underwriters' Securities of a defaulting Underwriter or Underwriters by the
Representatives and the Company as provided in subsection (a) above, the
aggregate amount of Underwriters' Securities which remains unpurchased exceeds
one-eleventh of the aggregate amount of the Designated Securities, as referred
to in subsection (b) above, or if the Company shall not exercise the right
described in subsection (b) above to require non-defaulting Underwriters to
purchase Underwriters' Securities of a defaulting Underwriter or Underwriters,
then the Pricing Agreement relating to such Designated Securities shall
thereupon terminate, without liability on the part of any non-defaulting
Underwriter or the Company, except for the expenses to be borne by the Company
and the Underwriters as provided in Section 6 hereof and the indemnity and
contribution agreements in Section 8 hereof; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

         10. The respective indemnities, agreements, representations, warranties
and other statements of the Company, Sallie Mae and the several Underwriters, as
set forth in this



                                       17
<PAGE>

Agreement or made by or on behalf of them, respectively, pursuant to this
Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Underwriter or any controlling person of any Underwriter, or the Company
or Sallie Mae or any officer or director or controlling person of the Company or
Sallie Mae, and shall survive delivery of and payment for the Securities.

         11. If any Pricing Agreement shall be terminated pursuant to Section 9
hereof, the Company and Sallie Mae shall not then be under any liability to any
Underwriter with respect to the Designated Securities covered by such Pricing
Agreement except as provided in Sections 6 and 8 hereof; but, if for any other
reason Underwriters' Securities are not delivered by or on behalf of the Company
as provided herein, except for any of the reasons specified in Section 7(j), the
Company and Sallie Mae will reimburse the Underwriters through the
Representatives for all out-of-pocket expenses approved in writing by the
Representatives, including fees and disbursements of counsel, reasonably
incurred by the Underwriters in making preparations for the purchase, sale and
delivery of such Designated Securities, but the Company and Sallie Mae shall
then be under no further liability to any Underwriter with respect to such
Designated Securities except as provided in Sections 6 and 8 hereof.

         12. In all dealings hereunder, the Representatives of the Underwriters
of Designated Securities shall act on behalf of each of such Underwriters, and
the parties hereto shall be entitled to act and rely upon any statement,
request, notice or agreement on behalf of any Underwriter made or given by such
Representatives jointly or by such of the Representatives, if any, as may be
designated for such purpose in the Pricing Agreement.

         All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Representatives as set forth in the
Pricing Agreement; and if to the Company or Sallie Mae shall be delivered or
sent by mail, telex or facsimile transmission to:

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 __________, 199__ (the
"Underwriting Agreement"), between the Company and Sallie Mae, on the one hand,
and _______________ and ________________, on the other hand, that the Company
will cause the trust (the "Trust") formed pursuant to the Trust Agreement dated
_______, 199__ between the Company and _______, as trustee (the "Eligible Lender
Trustee"), to issue and sell to the Underwriters named in Schedule I hereto (the
"Underwriters") the Student Loan-Backed Certificates (the "Certificates")
specified in Schedule II hereto (the "Designated Securities"). The Certificates
will be issued pursuant to the Trust Agreement.

         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 shall be deemed to be a representation
or warranty as of the date of the Underwriting Agreement in relation to the
Prospectus (as therein defined), and also a representation and warranty as of
the date of this Pricing Agreement in relation to the Prospectus as amended or
supplemented relating to the Designated Securities which are the subject of this
Pricing Agreement. Each reference to the Representatives herein and in the
provisions of the Underwriting Agreement so incorporated by reference shall be
deemed to refer to you. Unless otherwise defined herein, terms defined in 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.


<PAGE>

         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 the later of (i) [___
days after] the termination of trading restrictions for such Designated
Securities, as notified to the Company by the Representatives and (ii) [__ days
after] the Time of Delivery for such Designated Securities, 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 Services Act 1986
(Investment Advertisements) (Exemptions) Order 1995 or is a person to whom such
document may otherwise lawfully be issued or passed on.

         If the foregoing is in accordance with your understanding, please sign
and return to us ______ 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

         The Seller hereby represents and warrants to the Interim Eligible

         1.       The Seller 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

         2.       The Seller has the corporate power and authority to execute
                  and deliver this Agreement and to carry out its terms; and the
                  execution, delivery and performance of this Agreement has been
                  duly authorized by the Seller by all necessary corporate
                  action.

         3.       This Agreement constitutes a legal, valid and binding
                  obligation of the Seller 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.

         4.       The consummation of the transactions contemplated by this

                  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 Seller, or any indenture,
                  agreement or other instrument to which the Seller 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 other than as contemplated by the Basic
                  Documents); nor violate any law or any order, rule or
                  regulation applicable to the Seller of any court or of any
                  Federal or state regulatory body, administrative agency or
                  other governmental instrumentality having jurisdiction over
                  the Seller or its properties.

Trustee accepts the trust hereby created and agrees to perform its duties
hereunder with respect to such trust but only upon the terms of this Agreement.

<PAGE>

                  performance of any of its rights or powers hereunder or under
                  the Purchase Agreement or the Sale Agreement, if the Interim
                  Eligible Lender Trustee shall have reasonable grounds for
                  believing that repayment of such funds or adequate indemnity
                  against such risk or liability is not reasonably assured or
                  provided to it; and

         3.       the Interim Eligible Lender Trustee shall not be responsible
                  for or in respect of the validity or sufficiency of this
                  Agreement or for the due execution hereof by the Seller or for
                  the form, character, genuineness, sufficiency, value or
                  validity of any of the Interim Trust Loans or for or in
                  respect of the validity or sufficiency of the Purchase
                  Agreement or the Sale Agreement.

         SECTION 5.2 REPRESENTATIONS AND WARRANTIES. The Interim Eligible Lender
Trustee hereby represents and warrants to the Seller that:

         1.       It is duly organized and validly existing in good standing
                  under the laws of its governing jurisdiction and has an office
                  located within the State of Delaware. It has all requisite

         2.       It has taken all corporate action necessary to authorize the
                  execution and delivery by it of the Purchase Agreement, the
                  Sale Agreement and this Agreement, and the Purchase Agreement,
                  the Sale Agreement and this Agreement have been executed and

         3.       Neither the execution nor the delivery by it of the Purchase
                  Agreement, the Sale Agreement or this Agreement, nor the
                  consummation by it of the transactions contemplated thereby or
                  hereby nor compliance by it with any of the terms or
                  provisions thereof or hereof will contravene any Federal or
                  Delaware state law, governmental rule or regulation governing
                  the banking or trust powers of the Interim Eligible Lender
                  Trustee or any judgment or order binding on it, or constitute
                  any default under its charter documents or by-laws or any
                  indenture, mortgage, contract, agreement or instrument to
                  which it is a party or by which any of its properties may be


                                       5
<PAGE>

                  bound.

         4.       It is and will maintain its status 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 as contemplated by this Agreement, the Purchase
                  Agreement and the Sale Agreement.

         SECTION 5.3 NOT ACTING IN INDIVIDUAL CAPACITY. Except as provided in

Delaware acts solely as Interim Eligible Lender Trustee hereunder and not in its
individual capacity.

         SECTION 5.4 INTERIM ELIGIBLE LENDER TRUSTEE NOT LIABLE FOR THE INTERIM
TRUST LOANS. The Interim Eligible Lender Trustee makes no representations as to
the validity or sufficiency of this Agreement, the Purchase Agreement or the
Sale Agreement, or of any Interim Trust Loan or related documents. The Interim
Eligible Lender Trustee shall at no time have any responsibility for or with
respect to the sufficiency of the Interim Trust Loans; the validity or
completeness of the assignment to the Interim Eligible Lender Trustee of legal
title to any Interim Trust Loan on behalf and for the benefit of the Seller; the
performance or enforcement (except as expressly set forth in the Purchase
Agreement or the Sale Agreement) of any Interim Trust Loan; the compliance by
the Seller or the Servicer with any warranty or representation made under any
Basic Document or in any related document or the accuracy of any such warranty
or representation or any action or inaction of the Administrator, the Indenture
Trustee or the Servicer or any subservicer taken in the name of the Interim
Eligible Lender Trustee.


                                   ARTICLE VI

                                   ARTICLE VII

                     TERMINATION OF INTERIM TRUST AGREEMENT

         This Agreement (other than Article VI) and the trust created hereby
shall terminate and be of no further force or effect upon the earlier of (i) the
termination of the Trust pursuant to Section 9.1 of the Trust Agreement and (ii)
the expiration of 21 years from the death of the last survivor of the
descendants of Joseph P. Kennedy, the late Ambassador of the United States to
the Court of St. James, living on the date hereof.


                                  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>

                                  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

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

         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 9.3 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

delivered shall be an original, but all such counterparts shall together
constitute but one and the same instrument.

Initial Trust Estate and shall be deposited in the Collection Account. The
Depositor shall pay the organizational expenses of the Trust as they may arise
or shall, upon the request of the Eligible Lender Trustee, promptly reimburse

         SECTION II.6 DECLARATION OF TRUST. The Eligible Lender Trustee hereby

intention of the parties hereto that the Trust constitute a business trust
under Delaware law and that this Agreement constitute the governing instrument
of such trust. It is the intention of the parties hereto that, solely for income
tax purposes, the Trust shall be treated as a partnership, with the assets of
the partnership being the Trust Student Loans and other assets held by the
Trust, the partners of the partnership being the Certificateholders (including
the Depositor as recipient of distributions from the Reserve Account), and the
Notes being debt of the partnership. The parties agree that, unless otherwise
required by appropriate tax authorities, the Trust will file or cause to be
filed annual or other necessary returns, reports and other forms consistent with
the characterization of the Trust as a partnership for such tax purposes.
Effective as of the date hereof, the Eligible Lender Trustee shall have all
rights, powers and duties set forth herein with respect to accomplishing the
purposes of the Trust.

         SECTION II.7 LIABILITY OF THE CERTIFICATEHOLDERS.

         (a)      Notwithstanding the provisions of Section 3803 of the Delaware
                  Business Trust Act, the Depositor shall be liable directly to
                  and 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. 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 shall have any personal liability for any
                  liability or obligation of the Trust.

         SECTION II.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.

                  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 business is presently conducted.

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

         (c)      This Agreement constitutes a legal, valid and binding
                  obligation of the Depositor enforceable in accordance with its

                  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 certificates 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.

         (e)      The Depositor agrees for the benefit of the Noteholders and of
                  the Certificate Holders 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 II.10 APPLICATION OF TRUST FUNDS.

         (a)      INCOME AND LOSS ALLOCATIONS. After giving effect to the
                  special allocations set forth in subparagraph (b) of this
                  Section 2.10 and for purposes of maintaining Capital Accounts
                  under Section 5.6, gross income items of the Trust for any
                  Accrual Period as determined for Federal income tax purposes
                  shall be allocated as follows:

                           (1) first, among the Certificateholders as of the
                           close of business on the last day of such Accrual
                           Period, in proportion to the Certificate Balance of
                           the Certificates owned by them on such date, an
                           amount of gross income up to the sum of (i) the
                           portion of the Certificateholders' Return
                           Distribution Amount and the Certificate Return
                           Carryover, if any, for the related Distribution Date
                           allocable to such Accrual Period, (ii) return on the
                           excess, if any, of the Certificateholders' Return
                           Distribution Amount for the preceding Distribution
                           Date over the amount in respect of return on the
                           Certificates that is actually distributed to
                           Certificateholders on such preceding Distribution
                           Date, to the extent permitted by law, at the
                           Certificate Rate for such Accrual Period and (iii)
                           the portion of the market discount on the Trust
                           Student Loans accrued during such Accrual Period that
                           is allocable to the excess, if any, of the initial
                           aggregate principal amount of the Certificates over
                           their initial aggregate issue price; and

                           (2) the balance of Profits, if any, to the Depositor.

                  If the items of gross income of the Trust for any month are
                  insufficient for the allocations described in clause (1)
                  above, subsequent items of gross income shall first be
                  allocated to make up such shortfall before Profits are
                  allocated as provided in clause (b). Loss of the Trust for any
                  Accrual Period shall be allocated to the Depositor to the
                  extent the Depositor is reasonably expected to bear the
                  economic burden of such Loss, and any remaining Loss shall be
                  allocated among the Certificateholders as of the close of
                  business on the last day of such Accrual Period in proportion
                  to the Certificate Balance of Trust Certificates owned by them
                  on such date. If any items of loss or deduction are allocated
                  to


                                        5
<PAGE>

                  Certificateholders and the Depositor subsequently determines
                  that the economic loss to Certificateholders will be less than
                  was expected at the time such allocations were made,
                  additional items of gross income will be allocated to
                  Certificateholders in subsequent periods to offset the excess
                  allocations of losses and deductions to Certificateholders
                  before any Profits are allocated to the Depositor as provided
                  in clause (2) above.

         (b)      SPECIAL ALLOCATIONS.

                           (1) In the event any Certificateholder unexpectedly
                           receives any adjustments, allocations or
                           distributions described in Treasury Regulation
                           Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of
                           Trust income and gain shall be specially allocated to
                           such Certificateholder in an amount and manner
                           sufficient to eliminate, to the extent required by
                           the Treasury Regulations, the deficit, if any, in the
                           balance of the Capital Account of such
                           Certificateholder as quickly as possible. This
                           Section 2.10(b) is intended to comply with the
                           qualified income offset provision in Section
                           1.704-1(b)(2)(ii)(d) of the Treasury Regulations.

                           (2) In the event the initial issue price of
                           Certificates differs from their initial Certificate
                           Balance, there shall be specially allocated to the
                           Certificateholders the portion, if any, of the offset
                           for premium (in the case the issue price of the
                           Certificates exceeds the Certificate Balance) on the
                           Trust Student Loans accruing for a calendar month
                           that is attributable to such difference.

         (c)      LIQUIDATING PROFIT OR LOSS. Liquidating Profit or Loss shall
                  be allocated, after all other adjustments are made to the
                  Capital Accounts (including adjustments to reflect the
                  Liquidating Distribution), as follows:

                           (1) First, among the Certificateholders in proportion
                           to their ownership of the principal amount of
                           Certificates, in an amount that would cause their
                           Capital Account balances to equal zero (in the case
                           of the Depositor, taking into account the Capital
                           Account balance of the Depositor only to the extent
                           it relates to Certificates owned by the Depositor);
                           and

                           (2)      Any balance, to the Depositor.

         (d)      TAX ALLOCATIONS. For Federal income tax purposes, each item of
                  income, gain, loss and deduction of the Trust



                                       6
<PAGE>

                  shall be allocated among the Certificateholders and the
                  Depositor in a manner consistent with the allocations set
                  forth in this Section 2.10, subject to the provisions of
                  Section 704(c) of the Code. Notwithstanding anything to the
                  contrary set forth in this Agreement, the Depositor is
                  authorized to modify the allocations of this Section 2.10(d)
                  and Sections 2.10(a), (b) and (c) if necessary or appropriate,
                  in the Depositor's sole discretion, for the allocations to
                  fairly reflect the economic gain, income or loss to the
                  Depositor or the Certificateholders, or as otherwise required
                  by the Code or the Treasury Regulations.


                                   ARTICLE III

                  TRUST CERTIFICATES AND TRANSFER OF INTERESTS

         SECTION III.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 III.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 III.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 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



                                       7
<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 III.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 may be imposed in connection with any transfer or
exchange of Trust Certificates.



                                       8
<PAGE>

         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 III.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 III.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



                                       9
<PAGE>

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 III.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 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 III.8 MAINTENANCE OF OFFICE OR AGENCY. The Eligible Lender
Trustee shall maintain in the Borough of Brooklyn, 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, New York 10001, Attention: Structured Finance Services. The
Eligible Lender 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 III.9 APPOINTMENT OF CERTIFICATE PAYING AGENT. The Certificate
Paying Agent shall make distributions to Certificateholders from the amounts
received from the Indenture



                                       10

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

         SECTION III.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 distribution in respect of the
         Certificate Balance and return 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 specified percentage of the Certificate
         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



                                       12
<PAGE>

         Certificates and has delivered such instructions to the Eligible Lender
         Trustee.

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

                                    ARTICLE V

                   APPLICATION OF TRUST FUNDS; CERTAIN DUTIES

         SECTION V.1 APPLICATION OF TRUST FUNDS.

         (a)      On each Distribution Date, the Eligible Lender Trustee shall
                  distribute to Certificateholders (i) the Certificateholders'
                  Return Distribution Amount for such Distribution Date on a pro
                  rata basis according to



                                       15
<PAGE>

                  amounts payable in respect of Certificateholders' Return
                  Distribution Amount, (ii) the Certificate Balance
                  Distribution Amount for such Distribution Date, if any, on
                  a pro rata basis according to amounts payable in respect of
                  the Certificate Balance, and (iii) the Certificate Return
                  Carryover for such Distribution Date, if any, on a pro rata
                  basis according to amounts payable in respect of
                  Certificate Return Carryover, as received from the
                  Indenture Trustee pursuant to Sections 2.7 and 2.8 of the
                  Administration Agreement on such Distribution Date.

         (b)      On each Distribution Date, the Eligible Lender Trustee shall
                  send to each Certificateholder the statement provided to the
                  Eligible Lender Trustee by the Administrator pursuant to
                  Section 2.9 of the Administration Agreement on such
                  Distribution Date.

         (c)      In the event that any withholding tax is imposed on the
                  Trust's payment (or allocations of income) to a
                  Certificateholder, such tax shall reduce the amount otherwise
                  distributable to the Certificateholder in accordance with this
                  Section. The Eligible Lender Trustee is hereby authorized and
                  directed to retain from amounts otherwise distributable to the
                  Certificateholders sufficient funds for the payment of any tax
                  that is legally owed by the Trust (but such authorization
                  shall not prevent the Eligible Lender Trustee from contesting
                  any such tax in appropriate proceedings, and withholding
                  payment of such tax, if permitted by law, pending the outcome
                  of such proceedings). The amount of any withholding tax
                  imposed with respect to a Certificateholder shall be treated
                  as cash distributed to such Certificateholder at the time it
                  is withheld by the Trust to be remitted to the appropriate
                  taxing authority. The Eligible Lender Trustee shall withhold
                  or cause to be withheld at the maximum applicable rate
                  provided in section 1441, 1442 or 1446 of the Code with
                  respect to all distributions made to persons that are not
                  known to be U.S. Persons, within the meaning of the Code,
                  unless it is otherwise determined in the opinion of counsel.
                  In the event that a Certificateholder wishes to apply for a
                  refund of any such withholding tax, the Eligible Lender
                  Trustee shall reasonably cooperate with such Certificateholder
                  in making such claim so long as such Certificateholder agrees
                  to reimburse the Eligible Lender Trustee for any out-of-pocket
                  expenses incurred.



                                       16

         SECTION V.2 METHOD OF PAYMENT. Subject to Section 9.1(c), distributions
required to be made to Certificateholders on any Distribution Date shall be made
to each Certificateholder of record on the preceding Record Date either by wire
transfer, in immediately available funds, to the account of such

Registrar appropriate written instructions signed by two authorized officers, if
any, at least five Business Days prior to such Distribution Date and such
Certificateholder's Trust Certificates in the aggregate evidence a denomination
of not less than $1,000,000, or, if not, by check mailed to such
Certificateholder at the address of such Certificateholder appearing in the
Certificate Register; PROVIDED, HOWEVER, that, unless Definitive Certificates

registered on the Record Date in the name of the nominee of the Clearing Agency

transfer in immediately available funds to the account designated by such
nominee. Notwithstanding the foregoing, the final distribution in respect of any

CERTIFICATEHOLDERS, THE INTERNAL REVENUE SERVICE AND OTHERS. The Eligible Lender
Trustee shall (a) maintain (or cause to be maintained) the books of the Trust on

to be delivered) to each Certificateholder (and to each Person who was a

to prepare its Federal and state income tax returns, (c) file (or cause to be

as may from time to time be



                                       17
<PAGE>

required or appropriate under any applicable state or Federal statute or rule or
regulation thereunder so as to maintain the Trust's characterization as a
partnership for Federal income tax purposes, (d) cause such tax returns to be
signed in the manner required by law and (e) collect (or cause to be collected)
any withholding tax as described in and in accordance with Section 5.1(c) with
respect to income or distributions to Certificateholders. The Eligible Lender
Trustee shall elect under Section 1278 of the Code to include in income
currently any market discount that accrues with respect to the Trust Student
Loans. The Eligible Lender Trustee shall not make the election provided under
Section 754 of the Code. The Eligible Lender Trustee shall be entitled to hire
an independent accounting firm to perform the functions described in this
Section 5.4 the reasonable fees and expenses of which shall be paid by the
Depositor.

         SECTION V.5  SIGNATURE ON RETURNS; TAX MATTERS PARTNER.

         (a)      The Eligible Lender Trustee shall sign on behalf of the Trust
                  the tax returns of the Trust, unless applicable law requires a
                  Certificateholder to sign such documents, in which case such
                  documents shall be signed by the Depositor.

         (b)      The Depositor shall be designated the "tax matters partner" of
                  the Trust pursuant to Section 6231(a)(7)(A) of the Code and
                  applicable Treasury Regulations.

         SECTION V.6 CAPITAL ACCOUNTS. The Trust shall maintain accounts
("Capital Accounts") with respect to each Certificateholder (including the
Depositor) in accordance with the following provisions:

         (a)      Each Certificateholder's Capital Account shall be increased by
                  the Capital Contributions (as defined below) of such
                  Certificateholder, such Certificateholder's distributive share
                  of gross income (and any Liquidating Profits) and any items in
                  the nature of income or gain which are specially allocated to
                  such Certificateholder pursuant to Section 2.10(b) of this
                  Agreement.

         (b)      Each Certificateholder's Capital Account shall be reduced by
                  any amount distributed to such Certificateholder (including,
                  in the case of the Depositor, any amount released or otherwise
                  distributed to the Depositor from the Reserve Account under
                  Sections 2.8C(G) and 2.8D of the Administration Agreement) and
                  such Certificateholder's distributive



                                       18
<PAGE>

                  share of Losses and deductions (and any Liquidating Loss),
                  including any special allocation pursuant to Section 2.10(b).

         (c)      In the event all or a portion of a Certificate is transferred
                  in accordance with the terms of this Agreement, the transferee
                  shall succeed to the Capital Account of the transferor to the
                  extent it related to such Certificate or a portion thereof.

         (d)      Notwithstanding the above, the Capital Accounts shall be
                  adjusted in accordance with the provisions governing the
                  economic rights of the Certificateholders, as set forth herein
                  and in the Basic Documents.

         "Capital Contribution" means the amount of any cash and the fair market
value of any property contributed to the Trust by a Certificateholder (including
any amounts deemed to be contributed in connection with the original issuance of
the Certificates), including, in the case of the Depositor, the fair market
value of the Trust Student Loans deemed to be contributed by the Depositor to
the Trust, taking into account the provisions of Section 707(a)(2)(B) of the
Code and the Regulations thereunder. The foregoing provisions and the other
provisions of this Agreement relating to the maintenance of Capital Accounts are
intended to comply with section 1.704-1(b) of the Treasury Regulations and shall
be interpreted in a manner consistent therewith.

         SECTION VI.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

Eligible Lender Trustee to act.

         SECTION VI.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 and the other Basic Documents to which
the Trust is a party and to administer the Trust in the interest of the
Certificateholders, 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 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 VI.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



                                       20
<PAGE>

                  is contrary to the terms hereof or of 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 or 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 Agreement or 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



                                       21
<PAGE>

                  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 VI.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 Lender Trustee that are not related to
the ownership or the administration of the Trust Estate.

         SECTION VI.5 NO ACTION EXCEPT UNDER SPECIFIED DOCUMENTS OR
INSTRUCTIONS. The Eligible Lender Trustee shall not otherwise deal with any part
of the Trust Estate except (i) in accordance with the powers granted to and the
authority conferred upon the Eligible Lender Trustee pursuant to this Agreement,
(ii) in accordance with the other Basic Documents to which it is a party and
(iii) in accordance with any document or instruction delivered to the Eligible
Lender Trustee pursuant to Section 6.3.

         SECTION VI.6 RESTRICTIONS. The Eligible Lender Trustee shall not take
any action (a) that is inconsistent with the purposes of the Trust set forth in
Section 2.3 or (b) that, to the actual knowledge of the Eligible Lender Trustee,
would result in the Trust's becoming taxable as a corporation for Federal income
tax purposes. The Certificateholders shall not direct the Eligible Lender
Trustee to take action that would violate the provisions of this Section.

                  performance of any of its rights or powers hereunder or under
                  any other Basic Document, if the Eligible Lender Trustee shall
                  have reasonable grounds for believing that repayment of such

                  or direction of any of the Certificateholders, unless such
                  Certificateholders have offered to the Eligible Lender Trustee

                  other than the Depositor as described in Section 9.2, shall
                  not (x) operate to terminate this Agreement or the Trust, nor
                  (y) entitle such Certificateholder's legal representatives or
                  heirs to claim an 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

         (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

<PAGE>

                  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 IX.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



                                       29
<PAGE>

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 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 X.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 longterm
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



                                       30
<PAGE>

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 X.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 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.



                                       31
<PAGE>

         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 X.3 SUCCESSOR ELIGIBLE LENDER TRUSTEE. Any successor Eligible
Lender Trustee appointed pursuant to Section 10.2 shall execute, acknowledge and
deliver to the Administrator and to its predecessor Eligible Lender Trustee an
instrument accepting such appointment under this Agreement, and thereupon the
resignation or removal of the predecessor Eligible Lender Trustee shall become
effective and such successor Eligible Lender Trustee, without any further act,
deed or conveyance, shall become fully vested with all the rights, powers,
duties and obligations of its predecessor under this Agreement, with like effect
as if originally named as Eligible Lender Trustee. The predecessor Eligible
Lender Trustee shall upon payment of its fees and expenses deliver to the
successor Eligible Lender Trustee all documents, statements, moneys and
properties held by it under this Agreement and shall assign, if permissible, to
the successor Eligible Lender Trustee the lender identification number obtained
from the Department on behalf of the Trust; and the Administrator and the
predecessor Eligible Lender Trustee shall execute and deliver such instruments
and do such other things as may reasonably be required for fully and certainly
vesting and confirming in the successor Eligible Lender Trustee all such rights,
powers, duties and obligations.

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

         Upon acceptance of appointment by a successor Eligible Lender Trustee
pursuant to this Section, the Administrator shall mail notice of the successor
of such Eligible Lender Trustee to all Certificateholders, the Indenture
Trustee, the Noteholders and the Rating Agencies. 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 X.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 X.5 APPOINTMENT OF CO-ELIGIBLE LENDER TRUSTEE OR SEPARATE
ELIGIBLE LENDER TRUSTEE. Notwithstanding any other provisions of this Agreement,
at any time, for the purpose of meeting any legal requirements of any
jurisdiction in which any part of the Trust may at the time be located, the
Administrator and the Eligible Lender Trustee acting jointly shall have the
power and shall execute and deliver all instruments to appoint one or more
Persons approved by the Eligible Lender Trustee, meeting the eligibility
requirements of clauses (i) through (iii) of Section 10.1, to act as co-trustee,
jointly with the Eligible Lender Trustee, or separate trustee or separate
trustees, of all or any part of the Trust Estate, and to vest in such Person, in
such capacity, such title to the Trust Estate, or any part thereof, and, subject
to the other provisions of this Section, such powers, duties, obligations,
rights and trusts as the Administrator and the Eligible Lender Trustee may
consider necessary or desirable. If the Administrator shall not have joined in
such appointment within 15 days after the receipt by it of a request so to do,
the Eligible Lender Trustee alone shall have the power to make such appointment.
No co-trustee or separate trustee under this Agreement shall be required to meet
the terms of eligibility as a successor trustee pursuant to clauses (iv), (v)
and (vi) of Section 10.1 and no notice of the appointment of any co-trustee or
separate trustee shall be required pursuant to Section 10.3.

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

                  (i) all rights, powers, duties, and obligations conferred or
         imposed upon the Eligible Lender Trustee shall be conferred upon and
         exercised or performed by the Eligible Lender Trustee and such separate
         trustee or co-trustee



                                       33
<PAGE>

         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 cotrustee.

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

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

                                  MISCELLANEOUS

         SECTION XI.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 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 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 Balance, for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Agreement or of
modifying in any manner the rights of the Noteholders or the Certificateholders;
PROVIDED, HOWEVER, that no such amendment shall (a) increase or reduce in any
manner the amount of, or accelerate or delay the timing of, collections of
payments on Trust Student Loans or distributions that shall be required to be
made for the benefit of the Noteholders or the Certificateholders or (b) reduce
the aforesaid percentage of the Outstanding Amount of the Notes and the
Certificate Balance required to consent to any such amendment, without the
consent of all the outstanding Noteholders and Certificateholders.

         Promptly after the execution of any such amendment or consent, the
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



                                       35

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 XI.2 NO LEGAL TITLE TO TRUST ESTATE IN CERTIFICATEHOLDERS. The
Certificateholders shall not 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. No transfer, by operation of law or otherwise, of any right,
title, or interest of the Certificateholders to and in their beneficial
ownership interest in the Trust Estate shall operate 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.

         SECTION XI.3 LIMITATIONS ON RIGHTS OF OTHERS. Except for Section 2.7,
the provisions of this Agreement are solely for the benefit of the Eligible
Lender Trustee, the Depositor, the Certificateholders, the Administrator and, to
the extent expressly provided herein, the Indenture Trustee and the Noteholders,

implied, shall be construed to give to any other Person any legal or equitable
right, remedy or claim in the Trust Estate or under or in respect of this
Agreement or any covenants, conditions or provisions contained herein.

         SECTION XI.4  NOTICES.

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

         SECTION XI.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
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 XI.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.

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, all as herein

                  any bankruptcy proceedings under any United States Federal or

         (b)      The Eligible Lender Trustee (not in its individual capacity
                  but solely as Eligible Lender Trustee), by entering into this
                  Agreement, each Certificateholder, by accepting a Trust
                  Certificate, and the Indenture Trustee and each Noteholder by

officer, director or employee of any thereof and no recourse may be had against
such parties or their assets, except as may be expressly set forth or
contemplated in this Agreement, the Trust Certificates or the other Basic

                  FLOATING RATE STUDENT LOAN-BACKED CERTIFICATE

         evidencing a fractional undivided interest in the Trust, as defined
         below, the property of which includes a pool of student loans sold to
         the Trust by SLM Funding Corporation.

         (This Trust Certificate does not represent an interest in or obligation
         of SLM Funding Corporation, the Servicer (as defined below), the
         Eligible Lender Trustee (as defined below) or any of their respective

dollars non-assessable, fully-paid, fractional undivided interest in the SLM
Student Loan Trust 1999-3 (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
December 1, 1999 (the "Trust Agreement"), between the Depositor and Chase
Manhattan Bank Delaware, a Delaware banking corporation, not in its individual
capacity but


<PAGE>

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 September 13, 1999 for approximately $1,000,781,997 of
the loans in the Trust and September 20, 1999 for approximately $1,001,787,403
of the loans in the Trust, 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 December 1, 1999, 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,
return on the Certificate 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 day is not a Business Day, the next
succeeding Business Day) (each a "Distribution Date"), commencing on January 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



                                       2
<PAGE>

such Distribution Date pursuant to the Administration Agreement.

         The Certificate Rate for each Accrual Period shall be equal to the
lesser of (a) Three-Month LIBOR, except for the first Accrual Period, which
shall be One-Month LIBOR, on the second business day before the beginning of
that Accrual Period plus 0.40% per annum and (b) the Student Loan Rate for that
Accrual Period. The "Student Loan Rate" for any Accrual Period shall equal the
product of (a) the quotient obtained by dividing (i) 360 by (ii) the actual
number of days elapsed in such Accrual Period and (b) the percentage equivalent
of a fraction, (i) the numerator of which is equal to Expected Interest
Collections for the related Collection Period less the Primary Servicing Fee,
the Administration Fee and any prior unpaid Administration Fees with respect to
that Collection Period and (ii) the denominator of which is the Pool Balance as
of the first day of that Collection Period.

         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 Trust will be treated as a partnership
and the Certificateholders (including the Depositor in its capacity as
Certificateholder and as recipient of distributions from the Reserve Account)
will be treated as partners in that partnership. 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 partnership interests in the Trust.



                                       3
<PAGE>

         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 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

                         [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 options 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 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.



                                       8

         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




                                       9
<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.

                           AS ELIGIBLE LENDER TRUSTEE

         All defined terms are used herein as defined in the Trust Agreement

         EXISTENCE. The Depositor will maintain its corporate existence and its

         PROCEDURES OBSERVED. The Depositor will observe all corporate
procedures required by its Certificate of Incorporation, its by-laws and the

         RECORDS. The Depositor will maintain separate corporate records and

                                       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

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

the name of the Depositor except for items pursuant to the Facilities and
Services Agreement between the Depositor and its stockholder. The Depositor will

<PAGE>

         INTERCOMPANY 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 intercompany 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 intercompany 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 intercompany 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

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

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.

                                    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
$1,988,500,000. 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 (and any
Note Interest Carryover), 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

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

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 (and any
Note Interest Carryover) 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.

payable on each Distribution Date solely to the extent of funds required and
available to be distributed to Noteholders by the Indenture Trustee pursuant to
Section 2.7C.10, 2.8C(D), 2.8D or 2.8E of the Administration Agreement. Any Note
Interest Carryover




                                       9

payable on any Distribution Date shall be paid to the Person in whose name such
Note (or one or more Predecessor Notes) is registered on the applicable Record
Date by check mailed first-class postage prepaid to such Person's address as it
appears on the Note Register on such Record Date, except that, unless Definitive

(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. The funds represented by any such checks returned undelivered shall be
held in accordance with Section 3.3.

                  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

time deliver to the Indenture Trustee for cancellation any Notes previously
authenticated and delivered hereunder 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

Independent Certificates in accordance with TIA SSSS 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

<PAGE>

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;

conflict with any other provisions of this Indenture, the provisions of this
Section shall control;

                  (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

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-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

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



                                       12
<PAGE>

Person from a payment to any Noteholder of interest (including any Note Interest
Carryover) 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 Brooklyn, 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 3.3 MONEY FOR PAYMENTS TO BE HELD IN TRUST. As
provided in Section 8.2(a) and (b), all payments of amounts due and payable with

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

                  (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

                  (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 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



                                       14
<PAGE>

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;


                                       15
<PAGE>

                  (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 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 1999,
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,



                                       16
<PAGE>

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 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.


                                       17
<PAGE>

         (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; 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




                                       18
<PAGE>

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.

         (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



                                       19
<PAGE>

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;

                  (ii) claim any credit on, or make any deduction from the
principal or interest (including any Note Interest Carryover) 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; or

                  (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.
<PAGE>


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
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



                                       48
<PAGE>

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 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 Section 310(a) and
the requirements of an "eligible lender" under 20 USC Section 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 Section 310(b), including the optional provision permitted by
the second sentence of TIA Section 310(b)(9); PROVIDED, HOWEVER, that there
shall be excluded from the operation of TIA Section 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 Section 310(b)(1) are met.

                  SECTION 6.12 PREFERENTIAL COLLECTION OF CLAIMS AGAINST ISSUER.
The Indenture Trustee shall comply with TIA Section 311(a), excluding any
creditor relationship listed in TIA Section 311(b). An Indenture Trustee who has
resigned or been removed shall be subject to TIA Section 311(a) to the extent
indicated.

                  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,
that so long as the Indenture Trustee is the Note Registrar, no such list shall
be required to be furnished.

                  SECTION 7.2 PRESERVATION OF INFORMATION; COMMUNICATIONS TO
NOTEHOLDERS. The Indenture Trustee shall preserve, in as current a form as is
reasonably practicable, the names and addresses of the Noteholders contained in
the most recent list furnished to the Indenture Trustee as provided in Section
7.1 and the names and addresses of Noteholders received by the Indenture Trustee
in its capacity as Note Registrar. The Indenture Trustee may destroy any list
furnished to it as provided in such Section 7.1 upon receipt of a new list so
furnished.

         (a) Noteholders may communicate pursuant to TIA Section 312(b) with
other Noteholders with respect to their rights under this Indenture or under the
Notes. Upon receipt by the Indenture Trustee of any request by three or more
Noteholders or by one or more holders of Notes evidencing not less than 25% of
the Outstanding Amount of the Notes to receive a copy of the current list of
Noteholders (whether or not made pursuant to TIA Section 312(b)), the Indenture
Trustee shall promptly notify the Administrator thereof by providing to the
Administrator a copy of such request and a copy of the list of Noteholders
produced in response thereto.

         (b) The Issuer, the Indenture Trustee and the Note Registrar shall have
the protection of TIA Section 312(c).

         (c) On each Distribution Date the Indenture Trustee shall provide to
each Noteholder of record as of the related Record Date the information provided
by the Administrator to the Indenture Trustee on the related Determination Date
pursuant to Section 2.9 of the Administration Agreement.

         (d) The Indenture Trustee shall furnish to the Noteholders promptly
upon receipt of a written request therefor, duplicates or copies of all reports,

instruments furnished to the Indenture Trustee under the Basic Documents. The
Indenture Trustee shall furnish to the Noteholders promptly upon receipt thereof
from the Eligible Lender Trustee notice of any amendment of the Administration
Agreement pursuant to Section 8.5 of the Administration Agreement.

                  SECTION 7.3  REPORTS BY ISSUER. (a) The Issuer shall:

                  (i) file with the Indenture Trustee, within 15 days after the
Issuer is required to file the same with the Commission, copies of the annual

may be required from time to time by such rules and regulations; and

                  (iii) supply to the Indenture Trustee (and the Indenture
Trustee shall transmit by mail to all Noteholders described in TIA Section
313(c)) such summaries of any information, documents and reports required to be
filed by the Issuer pursuant to clauses (i) and (ii) of this Section 7.3(a) as
may be required by rules and regulations prescribed from time to time by the
Commission.

         (b) Unless the Issuer otherwise determines, the fiscal year of the

                      ACCOUNTS, DISBURSEMENTS AND RELEASES

                  SECTION 8.1 COLLECTION OF MONEY. Except as otherwise expressly
provided herein, the Indenture Trustee may demand payment or delivery of, and
shall receive and collect, directly and without intervention or assistance of
any fiscal agent or other intermediary, all money and other property payable to
or receivable by the Indenture Trustee pursuant to this Indenture. The Indenture
Trustee shall apply all such money received by it on behalf of Noteholders
pursuant to the Administration Agreement as provided in this Indenture. Except
as otherwise expressly provided in this Indenture, if any default occurs in the
making of any payment or performance under any agreement or instrument that is
part of the Indenture Trust Estate, the Indenture Trustee may take such action
as may be appropriate to enforce such payment or performance, including the
institution and prosecution of appropriate Proceedings. Any such action shall be
without prejudice to any right to claim a Default under this Indenture and any
right to proceed thereafter as provided in Article V.

                  (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

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

received to pay the Outstanding Amount of the Class A-1 Notes, the amounts so
received shall be applied to the payment of principal on the Class A-1 Notes on
a pro rata basis;

                  (iii) the Noteholders' Principal Distribution Amount, to the

Interest Carryover on a pro rata basis.

                  SECTION 8.3 GENERAL PROVISIONS REGARDING ACCOUNTS. (a) So long
as no Default shall have occurred and be continuing, all or a portion of the
funds in the Trust Accounts shall be invested in Eligible Investments and
reinvested by the Indenture Trustee upon Issuer Order, subject to the provisions
of Section 2.3B of the Administration Agreement. All income or other gain from
investments 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



                                       53
<PAGE>

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
deliver to the Indenture Trustee an Opinion of Counsel, acceptable to the
Indenture Trustee, to such effect.

         (b) Subject to Section 6.1(c), the Indenture Trustee shall not in any
way be held liable for the selection of Eligible Investments or by reason of any
insufficiency in any of the Trust Accounts resulting from any loss on any
Eligible Investment included therein except for losses attributable to the
Indenture Trustee's failure to make payments on such Eligible Investments issued
by the Indenture Trustee, in its commercial capacity as principal obligor and
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.

                  SECTION 8.4 RELEASE OF INDENTURE TRUST ESTATE. (a) Subject to
the payment of its fees and expenses pursuant to Section 6.7, the Indenture
Trustee may, and when required by the provisions of this Indenture shall,
execute 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 relying upon an instrument executed by the Indenture Trustee as
provided in this Article VIII shall be bound to ascertain the Indenture
Trustee's authority, inquire into the satisfaction of any conditions precedent
or see to the application of any moneys.

         (b) The Indenture Trustee shall, at such time as there are no Notes
Outstanding and all sums due the Indenture Trustee pursuant to Section 6.7 have
been paid, release any remaining portion of the Indenture Trust Estate that
secured the Notes



                                       54
<PAGE>

from the lien of this Indenture and release to the Issuer or 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 Sections 314(c) and
314(d)(1) meeting the applicable requirements of Section 11.1.

         (c) Each Noteholder, by the acceptance of a Note, acknowledges that
from time to time the Indenture Trustee shall release the lien of this Indenture
on any Trust Student Loan to be sold to (i) the Seller in accordance with
Section 6 of the Sale Agreement, (ii) to the Servicer in accordance with Section
3.5 of the Servicing Agreement and (iii) to another eligible lender holding one
or more Serial Loans with respect to such Trust Student Loan, in accordance with
Section 3.11E of the Servicing Agreement, and each Noteholder, by the acceptance
of a Note, consents to any such release.

                  SECTION 8.5 OPINION OF COUNSEL. The Indenture Trustee shall
receive at least seven days' notice when requested by the Issuer to take any
action pursuant to Section 8.4(a), accompanied by copies of any instruments
involved, 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.

<PAGE>

Indenture on any property at any time subject hereto or deprive any Noteholder

                  It shall not be necessary for any Act of Noteholders under
this Section to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such Act shall approve the substance
thereof.

liabilities or immunities under this Indenture or otherwise.

                  SECTION 9.4 EFFECT OF SUPPLEMENTAL INDENTURE. Upon the
execution of any supplemental indenture pursuant to the provisions hereof, this

this Indenture of the Indenture Trustee, the Issuer and the Noteholders shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

                  SECTION 9.5 CONFORMITY WITH TRUST INDENTURE ACT. Every
amendment of this Indenture and every supplemental indenture executed pursuant
to this Article IX



                                       59
<PAGE>

shall conform to the requirements of the Trust Indenture Act as then in effect
so long as this Indenture shall then be qualified under the Trust Indenture Act.

                  SECTION 9.6 REFERENCE IN NOTES TO SUPPLEMENTAL INDENTURES.
Notes authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article IX may, and if required by the Indenture
Trustee shall, bear a notation in form approved by the Indenture Trustee as to

Indenture Trustee shall so determine, new Notes so modified as to conform, in
the opinion of the Indenture Trustee and the Issuer, to any such supplemental
indenture may be prepared and executed by the Issuer and authenticated and
delivered by the Indenture Trustee in exchange for Outstanding Notes.

                                    ARTICLE X

                              REDEMPTION OF NOTES

                  SECTION 10.1 REDEMPTION. The Indenture Trustee shall, upon
receipt of written notice from the Eligible Lender Trustee or the Depositor
pursuant to Section 9.2 of the Trust Agreement of an Insolvency Event with
respect to the Depositor, give prompt written notice to the Noteholders of the
occurrence of such event. In the event that the assets of the Trust are sold
pursuant to Section 9.2 of the Trust Agreement, that portion of the amounts on
deposit in the Trust Accounts to be distributed to the Noteholders shall be paid
to the Noteholders up to the Outstanding Amount of the Notes and all accrued and
unpaid interest thereon and any accrued Note Interest Carryover with respect
thereto (but only to the extent provided by Sections 2.7(d) and 8.2(c)). If
amounts are to be paid to Noteholders pursuant to this Section 10.1, the notice
of such event from the Indenture Trustee to the Noteholders shall include notice
of the redemption of Notes by application of such amounts on the next
Distribution Date which is not sooner than 15 days after the date of such notice
(the "Redemption Date"), whereupon all such amounts shall be payable on the
Redemption Date.

                  SECTION 10.2 FORM OF REDEMPTION NOTICE. Notice of redemption
under Section 10.1 shall be given by the Indenture Trustee by first-class mail,
postage prepaid, or by facsimile, mailed or transmitted on or prior to the

the Record Date preceding the



                                       60
<PAGE>

applicable Redemption Date, at such Noteholder's address or facsimile number
appearing in the Note Register.

                  All notices of redemption shall state:

                  (i)      the Redemption Date;

                  (ii)     the Redemption Price; and

                  (iii) the place were such Notes are to be surrendered for
payment of the Redemption Price (which shall be the office or agency of the
Issuer to be maintained as provided in Section 3.2).

                  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 impair or affect the validity of the redemption of any other Note.

                  SECTION 10.3 NOTES PAYABLE ON REDEMPTION DATE. The Notes or
portions 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 Redemption Price) no interest shall accrue on the Redemption
Price for any period after the date to which accrued interest is calculated for
purposes of calculating the Redemption Price.

                  (iv) Whenever the Issuer is required to furnish to the
Indenture Trustee an Officers' Certificate of the Issuer certifying or stating

         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 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



                                       64
<PAGE>

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 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 1999-3, in
care of Chase Manhattan 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



                                       66
<PAGE>

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.

                  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.



                                       67
<PAGE>

                  The provisions of TIA Sections 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 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 Section 5-1401 of the New York General
Obligations Law), and the



                                       68
<PAGE>

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 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



                                       69
<PAGE>

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 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.

                  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 (including any Note Interest Carryover); 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



                                       27
<PAGE>


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 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.

                                    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 (including, subject
to the limitations of Sections 2.7(d) and 8.2(c), any Note Interest Carryover)
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



                                       28
<PAGE>


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

                  (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



                                       29
<PAGE>


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:

         (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 (including, subject to the limitations of
Sections 2.7(d) and 8.2(c), any Note Interest Carryover) 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 (and any Note Interest Carryover), with interest upon the
overdue



                                       30
<PAGE>


principal, and, to the extent payment at such rate of interest shall be legally
enforceable, upon overdue installments of interest (and any Note Interest
Carryover), 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.

         (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:



                                       31
<PAGE>


                  (i) to file and prove a claim or claims for the whole amount
of principal and interest (including any Note Interest Carryover) 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;

                  (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



                                       32
<PAGE>


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.

         (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;



                                       33
<PAGE>


                  (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 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 Balance plus accrued and unpaid return 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 Balance plus accrued and unpaid return thereon, the
Certificateholders of at least a majority of the Certificate 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.

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 (including any Note Interest
Carryover) 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.

                  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;



                                       36
<PAGE>


                  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 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



                                       37
<PAGE>


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 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.



                                       38
<PAGE>


                  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 (including, subject
to the limitations of Sections 2.7(d) and 8.2(c), any Note Interest Carryover)
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 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 (including any Note
Interest Carryover) 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



                                       39
<PAGE>


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 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.

                                       40
<PAGE>


         (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.



                                       41
<PAGE>


         (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

                  (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



                                       42
<PAGE>


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
fact or matter stated in such document.

         (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



                                       43
<PAGE>


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.

                  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 (including any Note Interest Carryover) 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



                                       44
<PAGE>


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
Section 313(a) if required by said section. The Indenture Trustee shall also
comply with TIA Section 313(b). A copy of each such report required pursuant
to TIA Section 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.

                  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



                                       45
<PAGE>


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 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
Trustee;

                  (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.



                                       46
<PAGE>


                  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.

                  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

                  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

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

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

                                [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 senior in right of 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 the lesser of (a) Three-Month LIBOR as determined on the second business day
before the beginning of that Accrual Period plus [specified percentage points]%
and (b) the Student Loan Rate for



                                       78
<PAGE>

such Accrual Period. The "Student Loan Rate" for any Accrual Period shall equal
the product of (a) the quotient obtained by dividing (i) 360 by (ii) the actual
number of days elapsed in such Accrual Period and (b) the percentage equivalent
of a fraction, (i) the numerator of which is equal to Expected Interest
Collections for the Collection Period relating to such Accrual Period less the
Primary Servicing Fee and the Administration Fee with respect to such Collection
Period, and (ii) the denominator of which is the Pool Balance as of the first
day of such Collection Period.

                  Any Note Interest Carryover that may exist on any Distribution
Date attributable to the Notes shall be payable to the Noteholders on that
Distribution Date and any succeeding Distribution Dates, solely out of the funds
available and required to be applied thereto pursuant to the Administration
Agreement.

                  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



                                       79
<PAGE>

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



                                       80
<PAGE>

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.

                  This Note shall be 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 and thereunder
shall be determined in accordance with such laws.

                  No reference herein to the Indenture and no provision of this
Note or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and interest on
this Note at the times, place, and rate, and in the coin or currency, herein
prescribed.

                  Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither Bankers Trust Company in its
individual capacity, Chase Manhattan Bank Delaware in its individual capacity,
any owner of a beneficial interest in the Issuer, nor any of their respective
partners, beneficiaries, agents, officers, directors, employees or successors or
assigns shall be personally liable for, nor shall recourse be had to any of them
for, the payment of principal of or interest on, or performance of, or omission
to perform, any of the covenants, obligations or indemnifications contained in
this Note or the Indenture; it being expressly understood that said covenants,
obligations and indemnifications have been made by the Eligible Lender Trustee
for the sole purposes of binding the interests of the Eligible Lender Trustee in
the assets of the Issuer. The Noteholder of this Note by the acceptance hereof
agrees that, except as expressly provided in the Basic Documents, in the case of
an Event of Default under the Indenture, the Noteholder shall have no claim
against any of the foregoing for any deficiency, loss or claim therefrom;

recourse to, and enforcement against, the assets of the Issuer for any and all
liabilities, obligations and undertakings contained in the Indenture or in this
Note.

                                [REVERSE OF NOTE]

                  This Note is one of a duly authorized issue of Notes of the
Issuer, designated as its Floating Rate Class A-2 Student Loan-Backed Notes (the
"Class A-2 Notes"), which, together with the Issuer's Floating Rate Class A-1
Student Loan-Backed Notes (the "Class A-1 Notes" and, together with the Class
A-2 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-2 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 senior in right of payment to the Class A-2
Notes as and to the extent provided in the Indenture.

                  Principal of the Class A-2 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-2 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-2 Notes shall be made pro rata to the Noteholders entitled thereto.

                  Interest on the Class A-2 Notes shall be payable on each
Distribution Date on the principal amount outstanding of the Class A-2 Notes
until the principal amount thereof is paid in full, at a rate per annum equal to
the Class A-2 Rate. The "Class A-2 Rate" for each Accrual Period shall be equal
to the lesser of (a) Three-Month LIBOR as determined on the second business day
before the beginning of that



                                       88
<PAGE>

Accrual Period plus [specified percentage points]% and (b) the Student Loan Rate
for such Accrual Period. The "Student Loan Rate" for any Accrual Period shall
equal the product of (a) the quotient obtained by dividing (i) 360 by (ii) the
actual number of days elapsed in such Accrual Period and (b) the percentage
equivalent of a fraction, (i) the numerator of which is equal to Expected
Interest Collections for the Collection Period relating to such Accrual Period
less the Primary Servicing Fee and the Administration Fee with respect to such
Collection Period, and (ii) the denominator of which is the Pool Balance as of
the first day of such Collection Period.

                  Any Note Interest Carryover that may exist on any Distribution
Date attributable to the Notes shall be payable to the Noteholders on that
Distribution Date and any succeeding Distribution Dates, solely out of the funds
available and required to be applied thereto pursuant to the Administration
Agreement.

                  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



                                       89

Trust Office or at the office of the Indenture Trustee's agent appointed for

                  The Issuer shall pay interest on overdue installments of
interest on this Note at the Class A-2 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

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

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



                                       90
<PAGE>

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

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

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

the 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.

                  No reference herein to the Indenture and no provision of this
Note or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and interest on
this Note at the times, place, and rate, and in the coin or currency, herein
prescribed.

individual capacity, Chase Manhattan Bank Delaware in its individual capacity,
any owner of a beneficial interest in the Issuer, nor any of their respective

promptly, in writing, upon the discovery of any breach of Sallie Mae's
representations and warranties made pursuant to Section 5 hereof which has a
materially adverse effect on the interest of Funding in any Trust Student Loan.

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

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
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, 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


                                       12
<PAGE>


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 shall not be required to reimburse Funding 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 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),


                                       13
<PAGE>


                  (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
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.


                                       14
<PAGE>


         (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

         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


                                       15
<PAGE>


             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
             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


                                       16
<PAGE>


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 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


                                       17
<PAGE>


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

         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


                                       18
<PAGE>


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 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 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 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


                                       19
<PAGE>


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.

         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

    to all the terms and conditions of the Purchase Agreement Master

         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

    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

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



                                       11
<PAGE>


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 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



                                       12
<PAGE>


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 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 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.



                                       14
<PAGE>


         (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 negligence in the performance of its duties under the Sale
         Agreement, or by reason of reckless disregard of its obligations and
         duties under the 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 and against, all costs, expenses, losses, claims, damages,
         obligations and liabilities arising out of, incurred in connection with
         or relating to the Sale Agreement, the other Basic Documents, the
         acceptance or performance 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 its
         representations or warranties in its individual capacity set forth in
         these Master Sale Terms or any Sale Agreement. In the event of any
         claim, action or proceeding for which indemnity will be sought pursuant
         to this 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.

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



                                       15
<PAGE>


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 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 and such agreement of assumption
comply with this Section and that all conditions precedent, if any, provided for
in these Master Sale Terms 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 the Seller is not the surviving entity, such
transaction will not result in a material adverse Federal or state tax
consequence to the Purchaser, the Noteholders or the Certificateholders and (v)
if the Seller is not the surviving entity, the Seller shall have delivered to
the 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 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.

<PAGE>


SECTION 12.  LIMITATION OF LIABILITY OF ELIGIBLE LENDER
                  TRUSTEE

          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.

be in writing and mailed or delivered to Seller or Purchaser, as the case may
be, addressed as set forth in the Sale Agreement or at such other address as

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

Certificateholders for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of such Master Sale Terms and
Sale 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 Eligible Lender Trustees, materially and
adversely affect the interest of any such Noteholder or Certificateholder.

amended from time to time by the Seller, the Interim Eligible Lender Trustee,
the Eligible Lender Trustee and the Purchaser, with the consent of the

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

of which are required to consent to any such amendment, without the consent of
all outstanding Noteholders and Certificateholders.

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.

         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)
of the Administration 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 18.  NONPETITION COVENANTS

         Notwithstanding any prior termination of these Master Sale Terms,
Seller and the Interim Eligible Lender Trustee shall not acquiesce, petition or

government authority for the purpose of commencing or sustaining a case against
Purchaser under any Federal or state bankruptcy, insolvency or similar law or
appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or
other similar official of Purchaser or any substantial part of its property, or
ordering the winding up or liquidation of the affairs of the Purchaser.

         Notwithstanding any prior termination of these Master Sale Terms, the

otherwise invoke or cause Seller to invoke the process of commencing or
sustaining a case against the Seller under any federal or state bankruptcy,
insolvency or similar law or appointing a receiver, liquidator, assignee,
trustee, custodian, sequestrator or other similar official of Seller or any
substantial part of its property, or ordering the winding up or liquidation of
the affairs of the Purchaser.

                             SALE AGREEMENT NUMBER 1

         Each of the Chase Manhattan Bank Delaware as Interim Eligible Lender
    Trustee (the "Interim Eligible Lender Trustee") for the benefit of SLM
    Funding Corporation (the "Seller") and the Seller hereby offer for sale to
    the Eligible Lender Trustee on behalf of SLM Student Loan Trust 1999-3
    ("Purchaser") the entire right, title and interest of the Seller and the
    Interim Eligible Lender Trustee in the Loans described in the Bill of Sale
    and Loan Transmittal Summary Form incorporated herein and, to the extent
    indicated below, the Eligible Lender Trustee on behalf of the Purchaser
    accepts the Seller's and the Interim Eligible Lender Trustee's offer. In
    order to qualify as Eligible Loans, no payment of principal or interest
    shall be more than one hundred and twenty (120) days Delinquent as of the

    $1,000,781,997 of the Loans in the Trust and September 20, 1999 for
    approximately $1,001,787,403 of the Loans in the Trust.

                         TERMS, CONDITIONS AND COVENANTS

         In consideration of the Purchase Price, each of the Seller and the
    Interim Eligible Lender Trustee for the benefit of the Seller hereby sells
    to the Eligible Lender Trustee for the benefit of the Purchaser the entire
    right, title and interest of the Seller and the Interim Eligible Lender
    Trustee in the Loans accepted for purchase, subject to all the terms and
    conditions of the Sale Agreement Master Securitization Terms Number 1000
    ("Master Sale Terms") and amendments, each incorporated herein by reference,
    among Seller, Interim Eligible Lender Trustee, Purchaser, and the Eligible
    Lender Trustee. The Initial Payment of the Loans shall equal $2,054,219,535
    (equal to $2,059,225,958 (representing the sale price of the Securities)
    less $5,006,423 (representing the Reserve Account Initial Deposit)).

         This document shall constitute a Sale Agreement as referred to in the
    Master Sale Terms and, except as modified herein, each term used herein
    shall have the same meaning as in the Master Sale Terms. All references in
    the Master Sale Terms to Loans or Eligible Loans shall be deemed to refer to
    the Loans governed by this Sale Agreement. Seller hereby makes, as of the

    applicable Guarantors of assignment to the Eligible Lender Trustee for the
    benefit of the Purchaser of the Loans on the date of purchase.

         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. However, in the event that notwithstanding the
    intentions of the parties, such transfer is deemed to be a transfer for
    security, then each of the Interim Eligible lender Trustee and the Seller
    hereby grants to the Eligible Lender Trustee on behalf of the Purchaser 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.

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 December 1, 1999, between SLM Funding Corporation and

         WHEREAS, the Issuer will issue notes (the "Notes") pursuant to an

         WHEREAS, the Issuer, the Administrator and the Eligible Lender Trustee
desire Servicer to service said education loans held by the Eligible Lender

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

                                    ARTICLE I

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.

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

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

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 RewardsSM, Great ReturnsSM and
Direct Repay), 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

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

creation or imposition of any Lien upon any of its properties pursuant to the

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

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:

             as applicable, representing not less than 25% of the Outstanding
             Amount of the Notes or not less than 25% of the outstanding
             Certificate 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

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
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.

the consent of any of the Noteholders or the Certificateholders, to comply with
any change in any applicable federal or state law, 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; PROVIDED, HOWEVER, that such action shall not, as

Servicer, the Issuer, the Administrator, the Eligible Lender Trustee and the
Indenture Trustee, with the consent of the Noteholders of Notes evidencing a

Seller) evidencing a majority of the Certificate Balance, for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Agreement or of modifying in any manner the rights of the
Noteholders or the Certificateholders; PROVIDED, HOWEVER, that no such amendment
shall (a) increase or reduce in any manner the amount of, or accelerate or delay
the timing of, collections of payments 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 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.

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