Credit Suisse First Boston Corporation
As Representative of the
several Underwriters
11 Madison Avenue
New York, N.Y. 10010


Dear Sirs:

                  1. Introductory. Key Bank USA, National Association, a
national banking association (the "Seller"), proposes to cause KeyCorp Student
Loan Trust 1999-A (the "Trust") to issue and sell $260,000,000 principal amount
of its Floating Rate Asset Backed Notes (the "Class A-1 Notes"), and
$570,400,000 principal amount of its Floating Rate Class A-2 Asset Backed Notes
(the "Class A-2 Notes" and together with the Class A-1 Notes, the "Notes"), to
the underwriters named in Schedule I hereto (the "Underwriters"), for whom you
(the "Representative") are acting as representative. The assets of the Trust
include, among other things, a pool of law school, medical school, dental
school, graduate business school and other graduate school student loans (the
"Financed Student Loans") and certain monies due thereunder on and after January
1, 1999 (the "Cutoff Date"). Such Financed Student Loans were sold to the
Eligible Lender Trustee (as defined below) on behalf of the Trust by the Seller
and are to be serviced by Pennsylvania Higher Education Assistance Agency, an
agency of the Commonwealth of Pennsylvania ("PHEAA" and, in its capacity as a
servicer, "Servicer") and EFS Services, Inc., a wholly-owned subsidiary of EFS,
Inc. of Indiana ("EFS" or a "Servicer"). The Notes will be issued pursuant to
the Indenture to be dated as of January 1, 1999 (as amended and supplemented
from time to time, the "Indenture"), between the Trust and Bankers Trust
Company, a New York banking corporation (the "Indenture Trustee").

                  Simultaneously with the issuance and sale of the Notes as
contemplated herein, the Trust will issue $34,600,000 principal amount of its
Floating Rate Asset Backed Certificates (the "Certificates"), representing a
fractional undivided ownership interest in the Trust, which will be sold
pursuant to an underwriting agreement dated the date hereof (the "Certificate
Underwriting Agreement") between the Seller and the Representative.

                  Capitalized terms used and not otherwise defined herein shall
have the meanings given them in Appendix A hereto.

                  2. Representations and Warranties of the Seller. (a) The
Seller represents and warrants to and agrees with the several Underwriters that:

                  (i) A registration statement (No. 333-58073), including a form
         of prospectus, on Form S-3 relating to the Notes, has been filed with
         the Securities and Exchange Commission (the "Commission") and either
         (A) has been declared effective under the Securities Act of 1933, as
         amended (the "Act"), and is not proposed to be amended or (B) is
         proposed to be amended by amendment or post-effective amendment. If the



                                      -2-
<PAGE>   3



         Seller does not propose to amend such registration statement and if any
         post-effective amendment to such registration statement has been filed
         with the Commission prior to the execution and delivery of this
         Agreement, the most recent such amendment has been declared effective
         by the Commission. For purposes of this Agreement, "Effective Time"
         means (x) if the Seller has advised the Representative that it does not
         propose to amend such registration statement, the date and time as of
         which such registration statement, or the most recent post-effective
         amendment thereto (if any) filed prior to the execution and delivery of
         this Agreement, was declared effective by the Commission, or (y) if the
         Seller has advised the Representative that it proposes to file an
         amendment or post-effective amendment to such registration statement,
         the date and time as of which such registration statement, as amended
         by such amendment or post-effective amendment, as the case may be, is
         declared effective by the Commission. "Effective Date" means the date
         of the Effective Time. Such registration statement, as amended at the
         Effective Time, including all information (if any) deemed to be a part
         of such registration statement as of the Effective Time pursuant to
         Rule 430A(b) under the Act, and including the exhibits thereto and any
         material incorporated by reference therein, is hereinafter referred to
         as the "Registration Statement", and the form of prospectus relating to
         the Notes, as first filed with the Commission pursuant to and in
         accordance with Rule 424(b) ("Rule 424(b)") under the Act or, if no
         such filing is required, as included in the Registration Statement at
         the Effective Date, is hereinafter referred to as the "Prospectus".

                  (ii) If the Effective Time is prior to the execution and
         delivery of this Agreement: (A) on the Effective Date, the Registration
         Statement conformed in all material respects to the requirements of the
         Act, the Trust Indenture Act of 1939, as amended (the "Trust Indenture
         Act"), and the rules and regulations of the Commission thereunder (the
         "Rules and Regulations") and did not include any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary in order to make the statements therein not
         misleading, (B) on the date of this Agreement, the Registration
         Statement conforms, and at the time of filing of the Prospectus
         pursuant to Rule 424(b), the Registration Statement and the Prospectus
         will conform, in all material respects to the requirements of the Act,
         the Trust Indenture Act and the Rules and Regulations, (C) on the
         Effective Date, the Registration Statement did not and will not contain
         any untrue statement of a material fact or omit to state any material
         fact required to be stated therein or necessary in order to make the
         statements therein not misleading and (D) on the Effective Date, the
         Prospectus, if not filed pursuant to Rule 424(b), did not or will not,
         and on the date of any filing pursuant to Rule 424(b) and on the
         Closing Date, the Prospectus will not, include any untrue statement of
         a material fact or omit to state a material fact necessary in order to
         make the statements therein, in light of the circumstances under which
         they are made, not misleading. If the Effective Time is subsequent to
         the execution and delivery of this Agreement: (1) on the Effective
         Date, the Registration Statement and the Prospectus will conform in all
         material respects to the requirements of the Act, the Trust Indenture
         Act and the Rules and Regulations, (2) on the Effective Date, the
         Registration Statement will not include any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary in order to make the statements therein not
         misleading and (3) on the 




                                      -3-
<PAGE>   4

         Effective Date, at the time of filing of the Prospectus pursuant to
         Rule 424(b) and at the Closing Date, the Prospectus will not include
         any untrue statement of a material fact or omit to state any material
         fact required to be stated therein or necessary in order to make the
         statements therein, in light of the circumstances under which they were
         made, not misleading. The two preceding sentences do not apply to
         statements in or omissions from the Registration Statement or
         Prospectus based upon written information furnished to the Seller by
         any Underwriter through the Representative specifically for use
         therein. As of the Closing Date (as defined below), the Seller's
         representations and warranties in the Sale and Servicing Agreement, the
         Supplemental Sale and Servicing Agreement, the Trust Agreement and the
         Guarantee Agreement to which TERI is a party will be true and correct
         in all material respects.

                  (iii) This Agreement has been duly authorized, executed and
         delivered by the Seller. The execution, delivery and performance of
         this Agreement and the issuance and sale of the Notes and compliance
         with the terms and provisions hereof will not result in a breach or
         violation of any of the terms and provisions of, or constitute a
         default under, any agreement or instrument to which the Seller is a
         party or by which the Seller is bound or to which any of the properties
         of the Seller is subject which could reasonably be expected to have a
         material adverse effect on the transactions contemplated herein. The
         Seller has full corporate power and authority to cause the Trust to
         authorize, issue and sell the Notes, all as contemplated by this
         Agreement.

                  (iv)  Other than as contemplated by this Agreement or as
         disclosed in the Prospectus, there is no broker, finder or other party
         that is entitled to receive from the Seller or any of its subsidiaries
         any brokerage or finder's fee or other fee or commission as a result of
         any of the transactions contemplated by this Agreement.

                  (v)   All legal or governmental proceedings, contracts or
         documents of a character required to be described in the Registration
         Statement or the Prospectus or to be filed as an exhibit to the
         Registration Statement have been so described or filed as required.

                  (vi)  The Seller's assignment and delivery of the Financed
         Student Loans to the Eligible Lender Trustee on behalf of the Trust as
         of the Closing Date will vest in the Eligible Lender Trustee on behalf
         of the Trust all the Seller's right, title and interest therein, or
         will result in a first priority perfected security interest therein, in
         either case subject to no prior lien, mortgage, security interest,
         pledge, adverse claim, charge or other encumbrance.

                (vii)   The Trust's assignment of the Financed Student Loans to
         the Indenture Trustee pursuant to the Indenture will vest in the
         Indenture Trustee, for the benefit of the holders of the Notes, a first
         priority perfected security interest therein, subject to no prior lien,
         mortgage, security interest, pledge, adverse claim, charge or other
         encumbrance.

               (viii) The Seller is not, and after giving effect to the offering
         and sale of the Notes, will not be an "investment company" or an entity
         "controlled" by an "investment company", 


                                      -4-

         of 1940, as amended (the "Investment Company Act");

jointly, to purchase from the Trust, at a purchase price of 99.78% of the

                  The Seller will deliver the Notes to the Representative for
the respective accounts of the Underwriters, against payment of the purchase
price to or upon the order of the Seller by wire transfer or check in Federal
(same day) Funds, at the office of Stroock & Stroock & Lavan LLP, 180 Maiden
Lane, New York, New York 10038, on February 9, 1999, or at such other time not
later than seven full business days thereafter as the Representative and the
Seller determine, such time being herein referred to as the "Closing Date". The
Notes to be so delivered will be initially represented by one or more Notes of
each class registered in the name of Cede & Co., the nominee of The Depository
Trust Company ("DTC"). The interests of beneficial owners of the Notes will be
represented by book entries on the records of DTC and participating members
thereof. Definitive Notes will be available only under the limited circumstances
specified in the Indenture.

                  4.  Offering by the Underwriters. It is understood that, after
the Registration Statement becomes effective, the several Underwriters propose
to offer the Notes for sale to the public (which may include selected dealers)
as set forth in the Prospectus.

                  5.  Covenants of the Seller. The Seller covenants and agrees
with the several Underwriters that:

                  (a) If the Effective Time is prior to the execution and
delivery of this Agreement, the Seller will file the Prospectus, properly
completed, with the Commission pursuant to and in accordance with subparagraph
(1) (or, if applicable and if consented to by the Representative, subparagraph
(4)) of Rule 424(b) not later than the earlier of (i) the second business day
following the execution and delivery of this Agreement and (ii) the fifth
business day after the Effective Date. The Seller will advise the Representative
promptly of any such filing pursuant to Rule 424(b).



                                      -5-
<PAGE>   6

                  (b) The Seller will advise the Representative promptly of any
proposal to amend or supplement the registration statement as filed or the
related prospectus or the Registration Statement or the Prospectus and will not
effect such amendment or supplementation without the consent of the
Representative prior to the Closing Date, and thereafter will not effect any
such amendment or supplementation to which the Representative reasonably
objects; the Seller will also advise the Representative promptly of any request
by the Commission for any amendment of or supplement to the Registration
Statement or the Prospectus or for any additional information; and the Seller
will also advise the Representative promptly of the effectiveness of the
Registration Statement (if the Effective Time is subsequent to the execution of
this Agreement) and of any amendment or supplement to the Registration Statement
or the Prospectus and of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement or the institution or
threat of any proceeding for that purpose and the Seller will use its best
efforts to prevent the issuance of any such stop order and to obtain as soon as
possible the lifting of any issued stop order.

                  (c) If, at any time when a prospectus relating to the Notes is
required to be delivered under the Act, any event occurs as a result of which
the Prospectus as then amended or supplemented would contain an untrue statement
of a material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or if it is necessary at any time to amend or supplement
the Prospectus to comply with the Act, the Seller promptly will prepare and
file, or cause to be prepared and filed, with the Commission an amendment or
supplement which will correct such statement or omission, or an amendment or
supplement which will effect such compliance. Neither the consent of the
Representative to, nor the delivery of the several Underwriters of, any such
amendment or supplement shall constitute a waiver of any of the conditions set
forth in Section 6.

                  (d) As soon as practicable, but not later than the
Availability Date (as defined below), the Seller will cause the Trust to make
generally available to the holders of the Notes an earnings statement of the
Trust covering a period of at least twelve months beginning after the Effective
Date which will satisfy the provisions of Section 11(a) of the Act and Rule 158
of the applicable Rules and Regulations thereunder. For the purpose of the
preceding sentence, "Availability Date" means the 45th day after the end of the
fourth fiscal quarter following the fiscal quarter that includes the Effective
Date, except that, if such fourth fiscal quarter is the last quarter of the
Trust's fiscal year, "Availability Date" means the 90th day after the end of
such fourth fiscal quarter.

                  (e) The Seller will furnish to the Representative copies of
the Registration Statement (two of which will be signed and will include all
exhibits), each related preliminary prospectus, the Prospectus and all
amendments and supplements to such documents, in each case as soon as available
and in such quantities as the Representative reasonably requests.

                  (f) The Seller will arrange for the qualification of the Notes
for sale under the laws of the States of New York, Hawaii and Washington D.C.
and will continue such qualifications in effect so long as required for the
distribution.

                  (g) For a period from the date of this Agreement until the
retirement of the Notes, or until such time as the several Underwriters shall
cease to maintain a secondary market in the Notes, whichever occurs first, the
Seller will deliver to the Representative the annual statements of compliance
and the annual independent certified public accountants' reports furnished to
the Indenture Trustee or the Eligible Lender Trustee pursuant to the Sale and
Servicing Agreement, as soon as such statements and reports are furnished to the
Indenture Trustee or the Eligible Lender Trustee.

                  (h) So long as any of the Notes is outstanding, the Seller
will furnish to the Representative (i) as soon as practicable after the end of
the fiscal year all documents required to be distributed to the holders of the
Notes or filed with the Commission on behalf of the Trust pursuant to the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), or any order
of the Commission thereunder and (ii) from time to time, any other information
concerning the Seller as the Representative may reasonably request only insofar
as such information reasonably relates to the Registration Statement or the
transactions contemplated by the Basic Documents.

                  (i) On or before the Closing Date, the Seller shall mark its
accounting and other records, if any, relating to the Initial Financed Student
Loans and shall cause each Servicer to mark the computer records of such
Servicer relating to the Financed Student Loans to show the absolute ownership
by the Eligible Lender Trustee on behalf of the Trust of the Financed Student
Loans, and from and after the Closing Date the Seller shall not and shall
require that any Servicer shall not take any action inconsistent with the
ownership by the Eligible Lender Trustee on behalf of the Trust of such Initial
Financed Student Loans, other than as permitted by the Sale and Servicing
Agreement.

                  (j) To the extent, if any, that the rating provided with
respect to the Notes by the rating agency or agencies that initially rate the
Notes is conditional at the time of issuance of the Notes upon the furnishing of
documents or the taking of any other actions by the Seller agreed upon on or
prior to the Closing Date, the Seller shall furnish such documents and take any
such other actions. A copy of any such document shall be provided to the
Representative at the time it is delivered to the rating agencies.

                  (k) For the period beginning on the date of this Agreement and
ending 90 days after the Closing Date, neither the Seller nor any trust
originated, directly or indirectly, by the Seller will, without the prior
written consent of the Representative, offer to sell or sell notes (other than
the Notes) collateralized by, or certificates (other than the Certificates)
evidencing an ownership interest in, student loans; provided, however, that this
shall not be construed to prevent the sale of student loans by the Seller.

                  (l) The Seller will apply the net proceeds of the offering and
the sale of the Notes and the Certificates that it receives in the manner set
forth in the Prospectus under the caption "Use of Proceeds."

                  (m) The Seller will pay all expenses incident to the
performance of its obligations under this Agreement, including (i) the printing
and filing of the documents (including the Registration Statement and
Prospectus) (ii) the preparation, issuance and delivery 



                                      -7-
<PAGE>   8

of the Notes to the Representative, (iii) the fees and disbursements of the
Seller's counsel and accountants, (iv) the qualification of the Notes under
securities laws in accordance with the provisions of Section 5(f), including
filing fees and the fees and disbursements of counsel for the Representative in
connection therewith and in connection with the preparation of any blue sky or
legal investment survey, if any is requested, (v) the printing and delivery to
the Representative of copies of the Registration Statement as originally filed
and of each amendment thereto, (vi) the printing and delivery to the
Representative of copies of any blue sky or legal investment survey prepared in
connection with the Notes, (vii) any fees charged by rating agencies for the
rating of the Notes, (viii) the fees and expenses, if any, incurred with respect
to any filing with the National Association of Securities Dealers, Inc. and (ix)
the fees and expenses of Thompson Hine & Flory LLP in its role as counsel to the
Trust incurred as a result of providing the opinions required by Section 6(h)
hereof.

                  6.  Conditions of the Obligations of the Underwriters. The
obligations of the several Underwriters to purchase and pay for the Notes will
be subject to the accuracy of the representations and warranties on the part of
the Seller herein, to the accuracy of the written statements of officers of the
Seller made pursuant to the provisions of this Section, to the performance by
the Seller of its obligations hereunder and to the following additional
conditions precedent:

                  (a) If the Effective Time is not prior to the execution and
delivery of this Agreement, the Effective Time shall have occurred not later
than 6:00 p.m., New York City time, on the date of this Agreement or such later
time or date as shall have been consented to by the Representative.

                  (b) If the Effective Time is prior to the execution and
delivery of this Agreement, the Prospectus and any supplements thereto shall
have been filed with the Commission in accordance with the Rules and Regulations
and Section 5(a) hereof. Prior to the Closing Date, no stop order suspending the
effectiveness of the Registration Statement shall have been issued and no
proceedings for that purpose shall have been instituted or, to the knowledge of
the Seller or the Representative, shall be contemplated by the Commission.

                  (c) The Representative shall have received a letter, dated the
date of delivery thereof (which, if the Effective Time is prior to the execution
and delivery of this Agreement, shall be on or prior to the date of this
Agreement or, if the Effective Time is subsequent to the execution and delivery
of this Agreement, shall be prior to the filing of the amendment or
post-effective amendment to the Registration Statement to be filed shortly prior

(ii) KPMG Peat Marwick LLP with respect to certain agreed-upon procedures with
respect to the Programs, in each case confirming that such accountants are

<PAGE>   9

                  (d) Subsequent to the execution and delivery of this
Agreement, there shall not have occurred (i) any change, or any development
involving a prospective change, in or affecting particularly the business or
properties of the Trust, the Seller, a Servicer or KeyCorp which, in the
judgment of the Representative, materially impairs the investment quality of the
Notes or makes it impractical or inadvisable to market the Notes; (ii) any
downgrading in the rating of any debt securities of the Seller or KeyCorp by any
"nationally recognized statistical rating organization" (as defined for purposes
of Rule 436(g) under the Act), or any public announcement that any such
organization has under surveillance or review its rating of any debt securities
of the Seller or KeyCorp (other than an announcement with positive implications
of a possible upgrading, and no implication of a possible downgrading, of such
rating); (iii) any suspension or limitation of trading in securities generally
on the New York Stock Exchange, or any setting of minimum prices for trading on
such exchange; (iv) any suspension of trading of any securities of the Seller or
KeyCorp on any exchange or in the over-the-counter market; (v) any banking
moratorium declared by Federal or New York authorities; or (vi) any 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 (vi) in the judgment of the Representative makes it
impracticable or inadvisable to proceed with the public offering or the delivery
of the Notes on the terms and in the manner contemplated in the Prospectus.

                  (e) The Representative shall have received an opinion of
Forrest F. Stanley, Esq., General Counsel of Key Bank USA, National Association

dated the Closing Date, in the form attached hereto as Exhibit A, or as is

                  (f) The Representative shall have received an opinion of

form attached hereto as Exhibit B, or as is otherwise satisfactory in form and
substance to the Representative and its counsel.

                  (g) The Representative shall have received an opinion of
Kirkpatrick & Lockhart LLP, counsel to the Seller, dated the Closing Date and
satisfactory in form and substance to the Representative and its counsel, to the
effect that the statements in the Prospectus under the headings "Summary of
Terms--Tax Considerations" and "Income Tax Consequences--Pennsylvania Income and
Franchise Tax Consequences with Respect to the Notes" accurately describe the
material Pennsylvania tax consequences to holders of the Notes.

                  (h) The Representative shall have received an opinion
addressed to the several Underwriters of Thompson Hine & Flory LLP, in its
capacity as Federal tax and ERISA counsel for the Trust, to the effect that the
statements in the Prospectus under the headings "Summary of Terms--Tax
Considerations" and "Income Tax Consequences--Federal Tax Consequences with
Respect to the Notes" accurately describe the material Federal income tax
consequences to holders of the Notes, and the statements in the Prospectus under
the headings "Summary of Terms--ERISA Considerations" and "ERISA Considerations"
to the extent that they constitute statements of matters of law or legal
conclusions with respect thereto, have been prepared or 



                                      -9-
<PAGE>   10

reviewed by such counsel and accurately describe the material consequences to
holders of the Notes under ERISA. Thompson Hine & Flory LLP, in its capacity as
special counsel to the Trust, shall have delivered an opinion with respect to
the characterization of the transfer of the Initial Financed Student Loans.

                  (i)  The Representative shall have received an opinion
addressed to the several Underwriters of Stroock & Stroock & Lavan LLP, in its
capacity as special counsel to the several Underwriters, dated the Closing Date,
with respect to the validity of the Notes and the Certificates and such other
related matters as the Representative shall reasonably require and the Seller
shall have furnished or caused to be furnished to such counsel such documents as
they may reasonably request for the purpose of enabling them to pass upon such
matters.

                  (j)  The Representative shall have received an opinion of Dean
Blakey & Moskowitz, special student loan counsel to the Representative and, in
the case of clause (iii) below, special student loan counsel to the Eligible
Lender Trustee, dated the Closing Date, satisfactory in form and substance to
the Representative, to the effect that:

                  (i)  the agreements implementing the Program, (including the
         Coordination Agreements (as such term is defined in the Supplemental
         Sale and Servicing Agreement)) and the Basic Documents, and the
         transactions contemplated by the Basic Documents, conform in all
         material respects to the applicable requirements of the Higher
         Education Act, and that, upon the due authorization, execution and
         delivery of the Basic Documents and the consummation of such
         transactions, the Financed Federal Loans, legal title to which will be
         held by the Eligible Lender Trustee on behalf of the Trust, will
         qualify, subject to compliance with all applicable origination and
         servicing requirements, for all applicable federal assistance payments,
         including federal reinsurance and federal interest subsidies and
         special allowance payments;

                  (ii) such counsel has examined the Registration Statement and
         the Prospectus, and nothing has come to such counsel's attention that
         would lead such counsel to believe that, solely with respect to the
         Higher Education Act and the student loan business, the Registration
         Statement or the Prospectus or any amendment or supplement thereto as
         of the respective dates thereof or on the Closing Date contains an
         untrue statement of a material fact or omits to state a material fact
         necessary in order to make the statements therein not misleading; and

                  (iii) the Eligible Lender Trustee is 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 Financed Federal Loans.

                  (k) The Representative shall have received an opinion of
counsel to PHEAA, dated the Closing Date and satisfactory in form and substance
to the Representative and its counsel, to the effect that:

                  (i) PHEAA has been duly organized and is validly existing as
         an agency of the Commonwealth of Pennsylvania in good standing under
         the laws thereof with full 


                                      -10-
<PAGE>   11

         power and authority (corporate and other) to own its properties and
         conduct its business, as presently conducted by it, and to enter into
         and perform its obligations under the Sale and Servicing Agreement, the
         Supplemental Sale and Servicing Agreement and the Guarantee Agreement
         (and the agreements with the Department under Section 428 of the Higher
         Education Act to the extent relevant to PHEAA's obligations under such
         Guarantee Agreement) to which it is a party, and had at all relevant
         times, and now has, the power, authority and legal right to service the
         Financed Student Loans it is servicing, to guarantee the Financed
         Federal Loans covered by such Guarantee Agreement and to receive,
         subject to compliance with all applicable conditions, restrictions and
         limitations of the Higher Education Act, reinsurance payments from the
         Department with respect to claims paid by it on such Financed Federal
         Loans.

                  (ii)  PHEAA is duly qualified to do business and is in good
         standing, and has obtained all necessary licenses and approvals in each
         jurisdiction in which failure to qualify or to obtain such license or
         approval would render any Financed Student Loan or PHEAA's obligation
         under its Guarantee Agreement unenforceable by or on behalf of the
         Trust.

                  (iii) Each of the Sale and Servicing Agreement, the
         Supplemental Sale and Servicing Agreement and the Guarantee Agreement
         (and the agreements with the Department under Section 428 of the Higher
         Education Act to the extent relevant to PHEAA's obligations under such
         Guarantee Agreement) to which PHEAA is a party has been duly
         authorized, executed and delivered by PHEAA and is the legal, valid and
         binding obligation of PHEAA enforceable against PHEAA in accordance
         with its terms, notwithstanding the existence of any doctrine of
         sovereign immunity except (x) the enforceability thereof may be subject
         to bankruptcy, insolvency, reorganization, moratorium or other similar
         laws now or hereafter in effect relating to creditors' rights and (y)
         the remedy of specific performance and injunctive and other forms of
         equitable relief may be subject to equitable defenses and to the
         discretion of the court before which any proceeding therefor may be
         brought.

                  (iv)  Neither the execution and delivery by PHEAA of the Sale
         and Servicing Agreement, the Supplemental Sale and Servicing Agreement
         or the Guarantee Agreement to which it is a party, nor the consummation
         by PHEAA of the transactions contemplated therein nor the fulfillment
         of the terms thereof by PHEAA will conflict with, result in a breach,
         violation or acceleration of, or constitute a default under, any term
         or provision of the certificate of incorporation or by-laws of PHEAA or
         of any indenture or other agreement or instrument to which PHEAA is a
         party or by which PHEAA is bound, or result in a violation of or
         contravene the terms of any statute, order or regulation applicable to
         PHEAA of any court, regulatory body, administrative agency or
         governmental body having jurisdiction over PHEAA.

                  (v)   There are no actions, proceedings or investigations
         pending or, to the best of such counsel's knowledge after due inquiry,
         threatened against PHEAA before or by any governmental authority that
         might materially and adversely affect the performance by 



                                      -11-
<PAGE>   12

         PHEAA of its obligations under, or the validity or enforceability of,
         the Sale and Servicing Agreement, the Supplemental Sale and Servicing
         Agreement or the Guarantee Agreement (or the agreements with the
         Department under Section 428 of the Higher Education Act to the extent
         relevant to PHEAA's obligations under such Guarantee Agreement) to
         which it is a party.

                  (vi)  Nothing has come to such counsel's attention that would
         lead such counsel to believe that the representations and warranties of
         PHEAA contained in the Sale and Servicing Agreement and the
         Supplemental Sale and Servicing Agreement are other than as stated
         therein.

                  (l)   The Representative shall have received an opinion of
counsel to EFS, dated the Closing Date and satisfactory in form and substance to
the Representative and its counsel, to the effect that:

                  (i) EFS has been duly organized and is validly existing as an
         Indiana corporation in good standing under the laws thereof with full
         power and authority (corporate and other) to own its properties and
         conduct its business, as presently conducted by it, and to enter into
         and perform its obligations under the Sale and Servicing Agreement and
         the Supplemental Sale and Servicing Agreement, and had at all relevant
         times, and now has, the power, authority and legal right to service the
         Financed Student Loans it is servicing.

                  (ii)  Each of the Sale and Servicing Agreement and the
         Supplemental Sale and Servicing Agreement has been duly authorized,
         executed and delivered by EFS and is the legal, valid and binding
         obligation of EFS enforceable against EFS in accordance with its terms,
         except (x) the enforceability thereof may be subject to bankruptcy,
         insolvency, reorganization, moratorium or other similar laws now or
         hereafter in effect relating to creditors' rights and (y) the remedy of
         specific performance and injunctive and other forms of equitable relief
         may be subject to equitable defenses and to the discretion of the court
         before which any proceeding therefor may be brought.

                  (iii) Neither the execution and delivery by EFS of the Sale
         and Servicing Agreement or the Supplemental Sale and Servicing
         Agreement, nor the consummation by EFS of the transactions contemplated
         therein nor the fulfillment of the terms thereof by EFS will conflict
         with, result in a breach, violation or acceleration of, or constitute a
         default under, any term or provision of the certificate of
         incorporation or by-laws of EFS or of any indenture or other agreement
         or instrument to which EFS is a party or by which EFS is bound, or
         result in a violation of or contravene the terms of any statute, order
         or regulation applicable to EFS of any court, regulatory body,
         administrative agency or governmental body having jurisdiction over
         EFS.

                  (iv)  There are no actions, proceedings or investigations
         pending or, to the best of such counsel's knowledge after due inquiry,
         threatened against EFS before or by any governmental authority that
         might materially and adversely affect the performance by EFS 



                                      -12-
<PAGE>   13

         of its obligations under, or the validity or enforceability of, the
         Sale and Servicing Agreement or the Supplemental Sale and Servicing
         Agreement.

                  (v) Nothing has come to such counsel's attention that would
         lead such counsel to believe that the representations and warranties of
         EFS contained in the Sale and Servicing Agreement and the Supplemental
         Sale and Servicing Agreement are other than as stated therein.

                  (m) The Representative shall have received an opinion of
counsel to the Massachusetts Higher Education Assistance Corporation, now doing
business as American Student Assistance, a Massachusetts non-profit corporation
("ASA"), dated the Closing Date and satisfactory in form and substance to the
Representative and its counsel, to the effect that:

                  (i) ASA has been duly incorporated and is validly existing as
         a non-profit corporation in good standing under the laws of the
         Commonwealth of Massachusetts with full power and authority (corporate
         and other) to own its properties and conduct its business, as presently
         conducted by it, and to enter into and perform its obligations under
         the Guarantee Agreement (and the agreements with the Department under
         Section 428 of the Higher Education Act to the extent relevant to ASA's
         obligations under such Guarantee Agreement) to which it is a party, and
         had at all relevant times, and now has, the power, authority and legal
         right to guarantee the Financed Federal Loans covered by such Guarantee
         Agreement and to receive, subject to compliance with all applicable
         conditions, restrictions and limitations of the Higher Education Act,

         the transactions contemplated in the Sale and Servicing Agreement, the
         Supplemental Sale and Servicing Agreement, the Indenture, the Trust
         Agreement or the Administration Agreement nor the fulfillment of the
         terms thereof by the Eligible Lender Trustee will conflict with, result
         in a breach or violation of, or constitute a default under any law or
         the charter, by-laws or other organizational documents of the Eligible
         Lender Trustee or the terms of any indenture or other agreement or

         Trustee or any of its subsidiaries is a party or is bound or any
         judgment, order or decree known to such counsel to be applicable to the
         Eligible Lender Trustee or any of its subsidiaries of any court,

         having jurisdiction over the Eligible Lender Trustee or any of its
         subsidiaries.

               (viii) There are no actions, suits or proceedings pending or, to
         the best of such counsel's knowledge after due inquiry, threatened
         against the Eligible Lender Trustee (as eligible lender trustee under
         the Trust Agreement or in its individual capacity) before or by any
         governmental authority that might materially and adversely affect the
         performance by the Eligible Lender Trustee of its obligations under, or
         the validity or enforceability of, the Trust Agreement, the Sale and
         Servicing Agreement or the Supplemental Sale and Servicing Agreement.

         Sale and Servicing Agreement, the Indenture, the Trust Agreement, the
         Administration Agreement or any Guarantee Agreement will not subject
         any of the property or assets of the Trust or any portion thereof, to
         any lien created by or arising under the Eligible Lender Trustee that
         are unrelated to the transactions contemplated in such agreements.

                  (t) The Representative shall have received certificates dated

Executive Vice President, Senior Vice President or Vice President, the
Secretary, any Assistant Secretary, the Treasurer, any Assistant Treasurer, the
principal financial officer or the principal accounting officer of each the

warranties of the Seller or the Servicers, as the case may be, contained in the
Trust Agreement, the Sale and Servicing Agreement and the Supplemental Sale and
Servicing Agreement, as applicable, are true and correct in all material
respects, that the Seller or the Servicers, as the case may be, has complied
with all agreements and satisfied all conditions on its part to be performed or
satisfied under such agreements at or prior to the Closing Date, in the case of
the certificate from the Seller only, that no stop order suspending the
effectiveness of the Registration Statement has been issued and no proceedings
for that purpose have been instituted or are contemplated by the Commission, and
(ii) since September 30, 1998, except as may be disclosed in the Prospectus or
in such certificate, no material adverse change, or any development involving a
prospective material adverse change, in or affecting particularly the business

the foregoing shall have placed either class of Notes under surveillance or
review with possible negative implications.

                  (w) The issuance of the Notes and the Certificates shall not
have resulted in a reduction or withdrawal by any Rating Agency of the current
rating of any outstanding securities issued or originated by the Seller or any
of its affiliates.

                  (x) On the Closing Date, $34,600,000 principal amount of the

circumstances under which they were made, not misleading.

                  The Seller will provide or cause to be provided to the
Representative such conformed copies of such of the foregoing opinions,
certificates, letters and documents as the Representative reasonably requests.

                  7. Indemnification and Contribution. (a) The Seller will
indemnify and hold each Underwriter harmless 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 any
untrue statement or alleged untrue statement of any material fact contained in
(x) the Registration Statement, 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 (y) the
Prospectus or any amendment or supplement thereto or any related preliminary
prospectus, or arise out of or are based upon the omission or alleged omission
to state therein a material fact necessary in order to make the statements
therein, in light of the circumstances under which that were made, 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 loss, claim, damage, liability or action as such expenses are
incurred; provided, however, that the Seller will 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 in or omission or
alleged omission from any of such documents in 



                                      -23-
<PAGE>   24

reliance upon and in conformity with written information furnished to the Seller
by any Underwriter through the Representative specifically for use therein.

                  (b) Each Underwriter will severally and not jointly indemnify
and hold harmless the Seller against any losses, claims, damages or liabilities
to which the Seller 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 any untrue statement or alleged untrue statement
of any material fact contained in the Registration Statement, the Prospectus or
any amendment or supplement thereto or any related preliminary prospectus, or
arise out of or are based upon the omission or the 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 reliance upon and in conformity with written
information relating to such Underwriter furnished to the Seller by such
Underwriter through the Representative specifically for use therein, and will
reimburse any legal or other expenses reasonably incurred by the Seller in
connection with investigating or defending any such loss, claim, damage,
liability or action as such expenses are incurred.


                  (c) Promptly after receipt by an indemnified party under this
Section of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under subsection (a) or (b) above, notify the indemnifying party of the
commencement thereof; but the omission so to notify the indemnifying party will
not relieve it from any liability which it may have to any indemnified party
otherwise than under subsection (a) or (b) above. In case any such action is
brought against any indemnified party and it notifies the indemnifying party of
the commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it may 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 and approval by the indemnified party of the
counsel appointed by the indemnifying party, the indemnifying party will not be
liable to such indemnified party under this Section for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation. In no event shall
the indemnifying party be liable for fees and expenses for more than one counsel
separate from their own counsel for all indemnified parties in connection with
any one action or related actions in the same jurisdiction arising out of the
same general allegations or circumstances unless any such indemnified party
shall have been advised by such counsel that there may be one or more legal
defenses available to it which are different from or additional to or in
conflict with those available to the other indemnified parties and in the
judgment of such counsel it is advisable for such indemnified party to employ
separate counsel. An indemnifying party will not, without the prior written
consent of the indemnified party, settle or compromise or consent to the entry
of any judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or 



                                      -24-
<PAGE>   25

potential parties to such claim or action) unless such settlement, compromise or
consent (i) includes an unconditional release of each 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 is
unavailable or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above, then each indemnifying party shall contribute to
the amount paid or payable by such indemnifying party as a result of the losses,
claims, damages or liabilities referred to in subsection (a) or (b) above (i) in
such proportion as is appropriate to reflect the relative benefits received by
the Seller on the one hand and the Underwriters on the other from the offering
of the Notes or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Seller on the one hand and the Underwriters on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities as well as any other relevant equitable
considerations. The relative benefits received by the Seller on the one hand and
the Underwriters on the other shall be deemed to be in the same proportion as
the total net proceeds from the offering (before deducting expenses) received by
the Seller bear to the total underwriting discounts and commissions received by
the 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 Seller or by the Underwriters and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such untrue statement or omission. The Company 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 referred to in
the first sentence of 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 action or claim which is the subject of this
subsection (d). 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 Notes 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, except as may be
provided in any agreement among the Underwriters relating to the offering of the
Notes. 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 in this subsection (d) to contribute are several in proportion
their respective underwriting obligations and not joint.

                  (e) The obligations of the Seller under this Section shall be
in addition to any liability which the Seller 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; 



                                      -25-
<PAGE>   26

and the obligations of the Underwriters under this Section 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 director of the Seller, to
each officer of the Seller who has signed the Registration Statement and to each
person, if any, who controls the Seller within the meaning of the Act.

                  8. Survival of Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of the
Seller or its officers and of the several Underwriters set forth in or made
pursuant to this Agreement or contained in certificates of officers of the
Seller submitted pursuant hereto shall remain operative and in full force and
effect, regardless of any investigation or statement as to the results thereof,
made by or on behalf of any Underwriter, the Seller or any of their respective
representatives, officers or directors or any controlling person, and will
survive delivery of and payment for the Notes. If for any reason the purchase of
the Notes by the Underwriters is not consummated, the Seller shall remain
responsible for the expenses to be paid or reimbursed by the Seller pursuant to
Section 5 and the respective obligations of the Seller and the Underwriters
pursuant to Section 7 shall remain in effect. If for any reason the purchase of
the Notes by the Underwriters is not consummated (other than pursuant to Section
9), the Seller will reimburse the Underwriters for all out-of-pocket expenses
(including fees and disbursements of counsel) reasonably incurred by them in
connection with the offering of the Notes.


                9.Failure to Purchase the Notes. If any Underwriter or
Underwriters default in their obligations to purchase its portion of the Notes
hereunder and the aggregate principal amount of the Notes that such defaulting
Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of
the total principal amount of the Notes, the Representative may make
arrangements satisfactory to the Seller for the purchase of such Notes by other
persons, including any of the Underwriters, but if no such arrangements are made
by the Closing Date, the non-defaulting Underwriters shall be obligated
severally, in proportion to their respective commitments hereunder, to purchase
the Notes that such defaulting Underwriters agreed but failed to purchase. If
any Underwriter or Underwriters so default and the aggregate principal amount of
the Notes with respect to such default or defaults exceeds 10% of the total
principal amount of the Notes and arrangements satisfactory to the
Representative and the Seller for the purchase of such Notes by other persons
are not made within 36 hours after such default, this Agreement will terminate
without liability on the part of any non-defaulting Underwriter or the Seller,
except as provided in Section 7. As used in this Agreement, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section. Nothing herein will relieve a defaulting Underwriter or Underwriters
from liability for its default.

                  10. Notices. All communications hereunder will be in writing
and, if sent to the Underwriters, will be mailed, delivered or telegraphed and
confirmed to the Representative at 11 Madison Avenue, New York, NY 10010,
Attention: Joseph Fashano; if sent to the Seller, will be mailed, delivered or
telegraphed and confirmed to it at Key Bank USA, National Association, 800
Superior Avenue, Cleveland, OH 44144, Attention: Senior Vice President,
Education Lending; provided, however, that any notice to an Underwriter pursuant
to Section 7 will be mailed, delivered or telegraphed and confirmed to such
Underwriter. Any such notice will take effect at the time of receipt.

                                      -26-
<PAGE>   27

                  11. Successors. This Agreement will inure to the benefit of
and be binding upon the parties hereto and their respective successors and the
officers and directors and controlling persons referred to in Section 7, and no
other person will have any right or obligations hereunder.

                  12. Representation of Underwriters. The Representative shall
act for the several Underwriters in connection with this financing, and any
action under this Agreement taken by the Representative will be binding upon all
the Underwriters.

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

                  14. Applicable Law. This Agreement will be governed by, and
construed in accordance with, the laws of the State of New York.

Credit Suisse First Boston Corporation
As Representative of the
several Underwriters
11 Madison Avenue
New York, N.Y. 10010


Dear Sirs:

                  1. Introductory. Key Bank USA, National Association, a
national banking association (the "Seller"), proposes to cause KeyCorp Student
Loan Trust 1999-A (the "Trust") to issue and sell $34,600,000 principal amount
of its Floating Rate Asset Backed Certificates (the "Certificates") to the
underwriters named in Schedule I hereto (the "Underwriters"), for whom you (the
"Representative") are acting as representative. The assets of the Trust include,
among other things, a pool of law school, medical school, dental school,
graduate business school and other graduate school student loans (the "Financed
Student Loans") and certain monies due thereunder on and after January 1, 1999
(the "Cutoff Date"). Such Financed Student Loans were sold to the Eligible
Lender Trustee (as defined below) on behalf of the Trust by the Seller and are
to be serviced by Pennsylvania Higher Education Assistance Agency, an agency of
the Commonwealth of Pennsylvania ("PHEAA" and, in such capacity as a servicer,
"Servicer") and EFS Services, Inc., a wholly owned subsidiary of EFS, Inc. of
Indiana ("EFS" and, in such capacity as a servicer, a "Servicer"). The
Certificates will be issued pursuant to the Amended and Restated Trust Agreement
to be dated as of January 1, 1999 (as amended and supplemented from time to
time, the "Trust Agreement"), between the Seller, as Depositor, and The First
National Bank of Chicago, a national banking association (the "Eligible Lender
Trustee").

                  Simultaneously with the issuance and sale of the Certificates
as contemplated herein, the Trust will issue $260,000,000 principal amount of
its Floating Rate Class A-1 Asset Backed Notes (the "Class A-1 Notes") and
$570,400,000 principal amount of its Floating Rate Class A-2 Asset Backed Notes
(the "Class A-2 Notes" and, with the Class A-1 Notes, the "Notes"). The Notes
will be sold pursuant to an underwriting agreement dated the date hereof (the
"Note Underwriting Agreement") between the Seller and the Representative.

                  Capitalized terms used and not otherwise defined herein shall
have the meanings given them in Appendix A hereto.

                  2. Representations and Warranties of the Seller. (a) The
Seller represents and warrants to and agrees with the several Underwriters that:

                  (i) A registration statement (No. 333-58073), including a form
         of prospectus, on Form S-3 relating to the Certificates, has been filed
         with the Securities and Exchange Commission (the "Commission") and
         either (A) has been declared effective under the Securities Act of
         1933, as amended (the "Act"), and is not proposed to be amended or (B)
         is proposed to be amended by amendment or post-effective amendment. If
         the Seller 



                                      -2-
<PAGE>   3

         does not propose to amend such registration statement and if any
         post-effective amendment to such registration statement has been filed
         with the Commission prior to the execution and delivery of this
         Agreement, the most recent such amendment has been declared effective
         by the Commission. For purposes of this Agreement, "Effective Time"
         means (x) if the Seller has advised the Representative that it does not
         propose to amend such registration statement, the date and time as of
         which such registration statement, or the most recent post-effective
         amendment thereto (if any) filed prior to the execution and delivery of
         this Agreement, was declared effective by the Commission, or (y) if the
         Seller has advised the Representative that it proposes to file an
         amendment or post-effective amendment to such registration statement,
         the date and time as of which such registration statement, as amended
         by such amendment or post-effective amendment, as the case may be, is
         declared effective by the Commission. "Effective Date" means the date
         of the Effective Time. Such registration statement, as amended at the
         Effective Time, including all information (if any) deemed to be a part
         of such registration statement as of the Effective Time pursuant to
         Rule 430A(b) under the Act, and including the exhibits thereto and any
         material incorporated by reference therein, is hereinafter referred to
         as the "Registration Statement," and the form of prospectus relating to
         the Certificates, as first filed with the Commission pursuant to and in
         accordance with Rule 424(b) ("Rule 424(b)") under the Act or, if no
         such filing is required, as included in the Registration Statement at
         the Effective Date, is hereinafter referred to as the "Prospectus."

                  (ii) If the Effective Time is prior to the execution and
         delivery of this Agreement: (A) on the Effective Date, the Registration
         Statement conformed in all material respects to the requirements of the
         Act, the Trust Indenture Act of 1939, as amended (the "Trust Indenture
         Act"), and the rules and regulations of the Commission thereunder (the
         "Rules and Regulations") and did not include any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary in order to make the statements therein not
         misleading, (B) on the date of this Agreement, the Registration
         Statement conforms, and at the time of filing of the Prospectus
         pursuant to Rule 424(b), the Registration Statement and the Prospectus
         will conform, in all material respects to the requirements of the Act,
         the Trust Indenture Act and the Rules and Regulations, (C) on the
         Effective Date, the Registration Statement did not and will not contain
         any untrue statement of a material fact or omit to state any material
         fact required to be stated therein or necessary in order to make the
         statements therein not misleading and (D) on the Effective Date, the
         Prospectus, if not filed pursuant to Rule 424(b), did not or will not,
         and on the date of any filing pursuant to Rule 424(b) and on the
         Closing Date, the Prospectus will not, include any untrue statement of
         a material fact or omit to state a material fact necessary in order to
         make the statements therein, in light of the circumstances under which
         they are made, not misleading. If the Effective Time is subsequent to
         the execution and delivery of this Agreement: (1) on the Effective
         Date, the Registration Statement and the Prospectus will conform in all
         material respects to the requirements of the Act, the Trust Indenture
         Act and the Rules and Regulations, (2) on the Effective Date, the
         Registration Statement will not include any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary in order to make the statements therein not
         misleading and (3) on the 



                                      -3-
<PAGE>   4

         Effective Date, at the time of filing of the Prospectus pursuant to
         Rule 424(b) and at the Closing Date, the Prospectus will not include
         any untrue statement of a material fact or omit to state any material
         fact required to be stated therein or necessary in order to make the
         statements therein, in light of the circumstances under which they were
         made, not misleading. The two preceding sentences do not apply to
         statements in or omissions from the Registration Statement or
         Prospectus based upon written information furnished to the Seller by
         any Underwriter through the Representative specifically for use
         therein. As of the Closing Date (as defined below), the Seller's
         representations and warranties in the Sale and Servicing Agreement, the
         Supplemental Sale and Servicing Agreement, the Trust Agreement and the
         Guarantee Agreement to which TERI is a party will be true and correct
         in all material respects.

                           (iii) This Agreement has been duly authorized,
         executed and delivered by the Seller. The execution, delivery and
         performance of this Agreement and the issuance and sale of the
         Certificates and compliance with the terms and provisions hereof will
         not result in a breach or violation of any of the terms and provisions
         of, or constitute a default under, any agreement or instrument to which
         the Seller is a party or by which the Seller is bound or to which any
         of the properties of the Seller is subject which could reasonably be
         expected to have a material adverse effect on the transactions
         contemplated herein. The Seller has full corporate power and authority
         to cause the Trust to authorize, issue and sell the Certificates, all
         as contemplated by this Agreement

                  (iv) Other than as contemplated by this Agreement or as
         disclosed in the Prospectus, there is no broker, finder or other party
         that is entitled to receive from the Seller or any of its subsidiaries
         any brokerage or finder's fee or other fee or commission as a result of
         any of the transactions contemplated by this Agreement.

                  (v) All legal or governmental proceedings, contracts or
         documents of a character required to be described in the Registration
         Statement or the Prospectus or to be filed as an exhibit to the
         Registration Statement have been so described or filed as required.

                  (vi) The Seller's assignment and delivery of the Financed
         Student Loans to the Eligible Lender Trustee on behalf of the Trust as
         of the Closing Date will vest in the Eligible Lender Trustee on behalf
         of the Trust all the Seller's right, title and interest therein, or
         will result in a first priority perfected security interest therein, in
         either case subject to no prior lien, mortgage, security interest,
         pledge, adverse claim, charge or other encumbrance.

                  (vii) The Trust's assignment of the Financed Student Loans to
         the Indenture Trustee pursuant to the Indenture will vest in the
         Indenture Trustee, for the benefit of the holders of the Notes, a first
         priority perfected security interest therein, subject to no prior lien,
         mortgage, security interest, pledge, adverse claim, charge or other
         encumbrance.

<PAGE>   5

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

                  (b) The Seller hereby agrees with the Underwriters that, for
all purposes of this Agreement, the only information furnished to the Seller by
the Underwriters through the Representative specifically for use in the
Registration Statement, the Prospectus, or any amendment or supplement thereto,
or any related preliminary prospectus, are the third paragraph and the second to
last paragraph of the cover page of, and the statements under the caption
"Underwriting" in, the preliminary prospectus and the Prospectus.

                  3. Purchase, Sale and Delivery of the Certificates. On the
basis of the representations, warranties and agreements herein contained, but
subject to the terms and conditions herein set forth, the Seller agrees to cause
the Trust to sell to the Underwriters, and the Underwriters agree, severally and
not jointly, to purchase from the Trust, at a purchase price of 99.515% of the
principal amount of the Certificates the respective principal amounts of
Certificates set forth opposite the names of the Underwriters in Schedule I
hereto. In addition, the Seller agrees to cause the Underwriters to be paid an
aggregate structuring fee in connection with the structuring of the Notes and
the Certificates of $864,567.

                  The Seller will deliver the Certificates to the Representative
for the respective accounts of the Underwriters, against payment of the purchase
price to or upon the order of the Seller by wire transfer or check in Federal
(same day) Funds, at the office of Stroock & Stroock & Lavan LLP, 180 Maiden
Lane, New York, New York 10038, on February 9, 1999, or at such other time not
later than seven full business days thereafter as the Representative and the
Seller determine, such time being herein referred to as the "Closing Date." The
Certificates to be so delivered will be initially represented by one or more
Certificates registered in the name of Cede & Co., the nominee of The Depository
Trust Company ("DTC"). The interests of beneficial owners of the Certificates
will be represented by book entries on the records of DTC and participating
members thereof. Definitive Certificates will be available only under the
limited circumstances specified in the Trust Agreement.

                  4. Offering by the Underwriters. It is understood that, after
the Registration Statement becomes effective, the several Underwriters propose
to offer the Certificates for sale to the public (which may include selected
dealers) as set forth in the Prospectus.

                  5. Covenants of the Seller. The Seller covenants and agrees
with the several Underwriters that:

                  (a) If the Effective Time is prior to the execution and
delivery of this Agreement, the Seller will file the Prospectus, properly
completed, with the Commission pursuant to and in accordance with subparagraph
(1) (or, if applicable and if consented to by the Representative, subparagraph
(4)) of Rule 424(b) not later than the earlier of (i) the second business day
following the execution and delivery of this Agreement and (ii) the fifth
business day after the Effective Date. 



                                      -5-
<PAGE>   6

The Seller will advise the Representative promptly of any such filing pursuant
to Rule 424(b).

                  (b) The Seller will advise the Representative promptly of any
proposal to amend or supplement the registration statement as filed or the
related prospectus or the Registration Statement or the Prospectus and will not
effect such amendment or supplementation without the consent of the
Representative prior to the Closing Date, and thereafter will not effect any
such amendment or supplementation to which the Representative reasonably
objects; the Seller will also advise the Representative promptly of any request
by the Commission for any amendment of or supplement to the Registration
Statement or the Prospectus or for any additional information; and the Seller
will also advise the Representative promptly of the effectiveness of the
Registration Statement (if the Effective Time is subsequent to the execution of
this Agreement) and of any amendment or supplement to the Registration Statement
or the Prospectus and of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement or the institution or
threat of any proceeding for that purpose and the Seller will use its best
efforts to prevent the issuance of any such stop order and to obtain as soon as
possible the lifting of any issued stop order.

                  (c) If, at any time when a prospectus relating to the
Certificates is required to be delivered under the Act, any event occurs as a
result of which the Prospectus as then amended or supplemented would contain an
untrue statement of a material fact or omit to state any material fact necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading, or if it is necessary at any time to amend or
supplement the Prospectus to comply with the Act, the Seller promptly will
prepare and file, or cause to be prepared and filed, with the Commission an
amendment or supplement which will correct such statement or omission, or an
amendment or supplement which will effect such compliance. Neither the consent
of the Representative to, nor the delivery of the several Underwriters of, any
such amendment or supplement shall constitute a waiver of any of the conditions
set forth in Section 6.

                  (d) As soon as practicable, but not later than the
Availability Date (as defined below), the Seller will cause the Trust to make
generally available to the holders of the Certificates an earnings statement of
the Trust covering a period of at least twelve months beginning after the
Effective Date which will satisfy the provisions of Section 11(a) of the Act and
Rule 158 of the applicable Rules and Regulations thereunder. For the purpose of
the preceding sentence, "Availability Date" means the 45th day after the end of
the fourth fiscal quarter following the fiscal quarter that includes the
Effective Date, except that, if such fourth fiscal quarter is the last quarter
of the Trust's fiscal year, "Availability Date" means the 90th day after the end
of such fourth fiscal quarter.

                  (e) The Seller will furnish to the Representative copies of
the Registration Statement (two of which will be signed and will include all
exhibits), each related preliminary prospectus, the Prospectus and all
amendments and supplements to such documents, in each case as soon as available
and in such quantities as the Representative reasonably requests.

                                      -6-
<PAGE>   7

                  (f) The Seller will arrange for the qualification of the
Certificates for sale under the laws of the States of New York, Hawaii and
Washington, D.C. and will continue such qualifications in effect so long as
required for the distribution.

                  (g) For a period from the date of this Agreement until the
retirement of the Certificates, or until such time as the several Underwriters
shall cease to maintain a secondary market in the Certificates, whichever occurs
first, the Seller will deliver to the Representative the annual statements of
compliance and the annual independent certified public accountants' reports
furnished to the Indenture Trustee or the Eligible Lender Trustee pursuant to
the Sale and Servicing Agreement, as soon as such statements and reports are
furnished to the Indenture Trustee or the Eligible Lender Trustee.

                  (h) So long as any of the Certificates is outstanding, the
Seller will furnish to the Representative (i) as soon as practicable after the
end of the fiscal year all documents required to be distributed to the holders
of the Certificates or filed with the Commission on behalf of the Trust pursuant
to the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or any
order of the Commission thereunder and (ii) from time to time, any other
information concerning the Seller as the Representative may reasonably request
only insofar as such information reasonably relates to the Registration
Statement or the transactions contemplated by the Basic Documents.

                  (i) On or before the Closing Date, the Seller shall mark its
accounting and other records, if any, relating to the Initial Financed Student
Loans and shall cause each Servicer to mark the computer records of such
Servicer relating to the Financed Student Loans to show the absolute ownership
by the Eligible Lender Trustee on behalf of the Trust of the Financed Student
Loans, and from and after the Closing Date neither the Seller shall not and
shall require that any Servicer shall not take any action inconsistent with the
ownership by the Eligible Lender Trustee on behalf of the Trust of such Initial
Financed Student Loans, other than as permitted by the Sale and Servicing
Agreement.

                  (j) To the extent, if any, that the rating provided with
respect to the Certificates by the rating agency or agencies that initially rate
the Certificates is conditional at the time of the issuance of the Certificates
upon the furnishing of documents or the taking of any other actions by the
Seller agreed upon on or prior to the Closing Date, the Seller shall furnish
such documents and take any such other actions. A copy of any such document
shall be provided to the Representative at the time it is delivered to the
rating agencies.

                  (k) For the period beginning on the date of this Agreement and
ending 90 days after the Closing Date, neither the Seller nor any trust
originated, directly or indirectly, by the Seller will, without the prior
written consent of the Representative, offer to sell or sell notes (other than
the Notes) collateralized by, or certificates (other than the Certificates)
evidencing an ownership interest in, student loans; provided, however, that this
shall not be construed to prevent the sale of student loans by the Seller.

                                      -7-
<PAGE>   8

                  (l) The Seller will apply the net proceeds of the offering and
the sale of the Certificates and the Notes that it receives in the manner set
forth in the Prospectus under the caption "Use of Proceeds."

                  (m) The Seller will pay all expenses incident to the
performance of its obligations under this Agreement, including (i) the printing
and filing of the documents (including the Registration Statement and
Prospectus) (ii) the preparation, issuance and delivery of the Certificates to
the Representative, (iii) the fees and disbursements of the Seller's counsel and
accountants, (iv) the qualification of the Certificates under securities laws in
accordance with the provisions of Section 5(f), including filing fees and the
fees and disbursements of counsel for the Representative in connection therewith
and in connection with the preparation of any blue sky or legal investment
survey, if any is requested, (v) the printing and delivery to the Representative
of copies of the Registration Statement as originally filed and of each
amendment thereto, (vi) the printing and delivery to the Representative of
copies of any blue sky or legal investment survey prepared in connection with
the Certificates, (vii) any fees charged by rating agencies for the rating of
the Certificates, (viii) the fees and expenses, if any, incurred with respect to
any filing with the National Association of Securities Dealers, Inc. and (ix)
the fees and expenses of Thompson Hine & Flory LLP in its role as counsel to the
Trust incurred as a result of providing the opinions required by Section 6(h)
hereof.

                  6. Conditions of the Obligations of the Underwriters. The
obligations of the several Underwriters to purchase and pay for the Certificates
will be subject to the accuracy of the representations and warranties on the
part of the Seller herein, to the accuracy of the written statements of officers
of the Seller made pursuant to the provisions of this Section, to the
performance by the Seller of its obligations hereunder and to the following
additional conditions precedent:

                  (a) If the Effective Time is not prior to the execution and
delivery of this Agreement, the Effective Time shall have occurred not later
than 6:00 p.m., New York City time, on the date of this Agreement or such later
time or date as shall have been consented to by the Representative.

                  (b) If the Effective Time is prior to the execution and
delivery of this Agreement, the Prospectus and any supplements thereto shall
have been filed with the Commission in accordance with the Rules and Regulations
and Section 5(a) hereof. Prior to the Closing Date, no stop order suspending the
effectiveness of the Registration Statement shall have been issued and no
proceedings for that purpose shall have been instituted or, to the knowledge of
the Seller or the Representative, shall be contemplated by the Commission.

                  (c) The Representative shall have received a letter, dated the
date of delivery thereof (which, if the Effective Time is prior to the execution
and delivery of this Agreement, shall be on or prior to the date of this
Agreement or, if the Effective Time is subsequent to the execution and delivery
of this Agreement, shall be prior to the filing of the amendment or
post-effective amendment to the Registration Statement to be filed shortly prior
to the Effective Time), of (i) Ernst & Young LLP on behalf of the Seller and
(ii) KPMG Peat Marwick LLP with 


                                      -8-
<PAGE>   9

respect to certain agreed-upon procedures with respect to the Programs, in each
case confirming that such accountants are independent public accountants within
the meaning of the Act and the applicable published Rules and Regulations
thereunder, and substantially in the form of the drafts to which the
Representative has previously agreed and otherwise in form and substance
reasonably satisfactory to the Representative and its counsel.

                  (d) Subsequent to the execution and delivery of this
Agreement, there shall not have occurred (i) any change, or any development
involving a prospective change, in or affecting particularly the business or
properties of the Trust, the Seller, a Servicer or KeyCorp which, in the
judgment of the Representative, materially impairs the investment quality of the
Certificates or makes it impractical or inadvisable to market the Certificates;
(ii) any downgrading in the rating of any debt securities of the Seller or
KeyCorp by any "nationally recognized statistical rating organization" (as
defined for purposes of Rule 436(g) under the Act), or any public announcement
that any such organization has under surveillance or review its rating of any
debt securities of the Seller or KeyCorp (other than an announcement with
positive implications of a possible upgrading, and no implication of a possible
downgrading, of such rating); (iii) any suspension or limitation of trading in
securities generally on the New York Stock Exchange, or any setting of minimum
prices for trading on such exchange; (iv) any suspension of trading of any
securities of the Seller or KeyCorp on any exchange or in the over-the-counter
market; (v) any banking moratorium declared by Federal or New York authorities;
or (vi) any 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 (vi) in the judgment of the
Representative makes it impracticable or inadvisable to proceed with the public

         Sale and Servicing Agreement)) and the Basic Documents, and the
         transactions contemplated by the Basic Documents, conform in all

         of the respective dates thereof or on the Closing Date contains an

         it, and to enter into and perform its obligations under the Sale and
         Servicing Agreement, the Supplemental Sale and Servicing Agreement and
         the Guarantee Agreement (and the agreements with the Department under
         Section 428 of the Higher Education Act to the extent relevant to
         PHEAA's obligations under such Guarantee Agreement) to which it is a
         party, and had at all relevant times, and now has, the power, authority
         and legal right to service the Financed Student Loans it is servicing,
         to guarantee the Financed Federal Loans covered by such Guarantee
         Agreement and to receive, subject to compliance with all applicable
         conditions, restrictions and limitations of the Higher Education Act,
         reinsurance payments from the Department with respect to claims paid by
         it on such Financed Federal Loans.

                  (ii) PHEAA is duly qualified to do business and is in good
         standing, and has obtained all necessary licenses and approvals in each
         jurisdiction in which failure to qualify or to obtain such license or
         approval would render any Financed Student Loan or PHEAA's obligation
         under its Guarantee Agreement unenforceable by or on behalf of the
         Trust.

                  (iii) Each of the Sale and Servicing Agreement, the
         Supplemental Sale and Servicing Agreement and the Guarantee Agreement
         (and the agreements with the Department under Section 428 of the Higher
         Education Act to the extent relevant to PHEAA's obligations under such
         Guarantee Agreement) to which PHEAA is a party has been duly
         authorized, executed and delivered by PHEAA and is the legal, valid and
         binding obligation of PHEAA enforceable against PHEAA in accordance
         with its terms, notwithstanding the existence of any doctrine of
         sovereign immunity except (x) the enforceability thereof may be subject
         to bankruptcy, insolvency, reorganization, moratorium or other similar
         laws now or hereafter in effect relating to creditors' rights and (y)
         the remedy of specific performance and injunctive and other forms of
         equitable relief may be subject to equitable defenses and to the
         discretion of the court before which any proceeding therefor may be
         brought.

                  (iv) Neither the execution and delivery by PHEAA of the Sale
         and Servicing Agreement, the Supplemental Sale and Servicing Agreement
         or the Guarantee Agreement to which it is a party, nor the consummation
         by PHEAA of the transactions contemplated therein nor the fulfillment
         of the terms thereof by PHEAA will conflict with, result in a breach,
         violation or acceleration of, or constitute a default under, any term
         or provision of the certificate of incorporation or by-laws of PHEAA or
         of any indenture or other agreement or instrument to which PHEAA is a
         party or by which PHEAA is bound, or result in a violation of or
         contravene the terms of any statute, order or regulation

         agency or governmental body having jurisdiction over PHEAA.

                  (v) There are no actions, proceedings or investigations
         pending or, to the best of such counsel's knowledge after due inquiry,
         threatened against PHEAA before or by any governmental authority that
         might materially and adversely affect the performance by PHEAA of its
         obligations under, or the validity or enforceability of, the Sale and
         Servicing Agreement, the Supplemental Sale and Servicing Agreement or
         the Guarantee Agreement (or the agreements with the Department under
         Section 428 of the Higher Education Act to the extent relevant to
         PHEAA's obligations under such Guarantee Agreement) to which it is a
         party.

                  (vi) Nothing has come to such counsel's attention that would
         lead such counsel to believe that the representations and warranties of
         PHEAA contained in the Sale and Servicing Agreement and the
         Supplemental Sale and Servicing Agreement are other than as stated
         therein.

         obligation of EFS enforceable against EFS in accordance with its terms,
         except (x) the enforceability thereof may be subject to bankruptcy,
         insolvency, reorganization, moratorium or other similar laws now or
         hereafter in effect relating to creditors' rights and (y) the remedy of
         specific performance and injunctive and other forms of equitable relief
         may be subject to equitable defenses and to the discretion of the court
         before which any proceeding therefor may be brought.

                  (iii) Neither the execution and delivery by EFS of the Sale
         and Servicing Agreement or the Supplemental Sale and Servicing
         Agreement, nor the consummation by EFS of the transactions contemplated
         therein nor the fulfillment of the terms thereof by EFS will conflict
         with, result in a breach, violation or acceleration of, or constitute a
         default under, any term or provision of the certificate of
         incorporation or by-laws of EFS or of any indenture or other agreement

         Servicing Agreement or the Supplemental Sale and Servicing Agreement.

                  (v) Nothing has come to such counsel's attention that would

         a corporation in good standing under the laws of the Commonwealth of
         Massachusetts with full power and authority (corporate and other) to
         own its properties and conduct its business, as presently conducted by
         it, and to enter into and perform its obligations under the Guarantee
         Agreement to which it is a party, and had at all relevant times, and
         now has, the power, authority and legal right to guarantee the Financed
         Private Loans covered by such Guarantee Agreement.

                  (ii) TERI is duly qualified to do business and is in good
         standing, and has obtained all necessary licenses and approvals in each

         qualify or to obtain such license or approval would render TERI's
         obligation under its Guarantee Agreement to guarantee the Financed
         Private Loans unenforceable by or on behalf of the Trust.

                  (iii) The Guarantee Agreement to which TERI is a party has
         been duly authorized, executed and delivered by TERI and is the legal,
         valid and binding obligation of TERI enforceable against TERI in
         accordance with its terms, except (x) the enforceability thereof may be
         subject to bankruptcy, insolvency, reorganization, moratorium or other
         similar laws now or hereafter in effect relating to creditors' rights
         and (y) the remedy of specific performance and injunctive and other
         forms of equitable relief may be subject to equitable defenses and to
         the discretion of the court before which any proceeding therefor may be
         brought.

                  (iv) Neither the execution and delivery by TERI of the
         Guarantee Agreement to which it is a party, nor the consummation by
         TERI of the transactions contemplated therein nor the fulfillment of
         the terms thereof by TERI will conflict with, result in a breach,
         violation or acceleration of, or constitute a default under, any term
         or provision of the certificate of incorporation or by-laws of TERI or
         of any indenture or other agreement or instrument to which TERI is a
         party or by which TERI is bound, or result in a violation of or
         contravene the terms of any statute, order or regulation applicable to
         TERI of any court, regulatory body, administrative agency or
         governmental body having jurisdiction over TERI.

                  (v) There are no actions, proceedings or investigations
         pending or, to the best of such counsel's knowledge after due inquiry,
         threatened against TERI before or by any governmental authority that
         might materially and adversely affect the performance by TERI of its
         obligations under, or the validity or enforceability of, the Guarantee
         Agreement to which it is a party.

         standing, and has obtained all necessary licenses and approvals in each
         jurisdiction in which failure to qualify or to obtain such license or

         Endorsement thereto to insure the Financed Private Loans unenforceable
         by or on behalf of the Trust.

                  (iii) The Surety Bonds and the Endorsement thereto to which
         HICA is a party have been duly authorized, executed and delivered by

         effect relating to creditors' rights and (y) the remedy of specific
         performance and injunctive and other forms of equitable relief may be
         subject to equitable defenses and to the discretion of the court before
         which any proceeding therefor may be brought.

                  (iv) Neither the execution and delivery by HICA of the Surety
         Bonds and the Endorsement thereto to which it is a party, nor the
         consummation by HICA of the transactions contemplated therein nor the
         fulfillment of the terms thereof by HICA will conflict with, result in
         a breach, violation or acceleration of, or constitute a default under,
         any term or provision of the certificate of incorporation or by-laws of
         HICA or of any indenture or other agreement or instrument to which HICA
         is a party or by which HICA is bound, or result in a violation of or
         contravene the terms of any statute, order or regulation applicable to
         HICA of any court, regulatory body, administrative agency or
         governmental body having jurisdiction over HICA.

                  (v) There are no actions, proceedings or investigations
         pending or, to the best of such counsel's knowledge after due inquiry,
         threatened against HICA before or by any governmental authority that

         obligations under, or the validity or enforceability of, the Surety
         Bonds and the Endorsement thereto to which it is a party.

                7. Indemnification and Contribution. (a) The Seller will
indemnify and hold each Underwriter harmless 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 any
untrue statement or alleged untrue statement of any material fact contained in
(x) the Registration Statement, 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 (y) the
Prospectus or any amendment or supplement thereto or any related preliminary
prospectus, or arise out of or are based upon the omission or alleged omission
to state therein a material fact necessary in order to make the statements
therein, in light of the circumstances under which that were made, 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 loss, claim, damage, liability or action as such expenses are
incurred; provided, however, that the Seller will 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 in or omission or
alleged omission from any of such documents in 


                                      -22-
<PAGE>   23

reliance upon and in conformity with written information furnished to the Seller
by any Underwriter through the Representative specifically for use therein.

                  (b) Each Underwriter will severally and not jointly indemnify
and hold harmless the Seller against any losses, claims, damages or liabilities
to which the Seller 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 any untrue statement or alleged untrue statement
of any material fact contained in the Registration Statement, the Prospectus or
any amendment or supplement thereto or any related preliminary prospectus, or
arise out of or are based upon the omission or the 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 reliance upon and in conformity with written
information relating to such Underwriter furnished to the Seller by such
Underwriter through the Representative specifically for use therein, and will
reimburse any legal or other expenses reasonably incurred by the Seller in
connection with investigating or defending any such loss, claim, damage,
liability or action as such expenses are incurred.

                  (c) Promptly after receipt by an indemnified party under this
Section of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under subsection (a) or (b) above, notify the indemnifying party of the
commencement thereof; but the omission so to notify the indemnifying party will
not relieve it from any liability which it may have to any indemnified party
otherwise than under subsection (a) or (b) above. In case any such action is
brought against any indemnified party and it notifies the indemnifying party of
the commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it may 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 and approval by the indemnified party of the
counsel appointed by the indemnifying party, the indemnifying party will not be
liable to such indemnified party under this Section for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation. In no event shall
the indemnifying party be liable for fees and expenses for more than one counsel
separate from their own counsel for all indemnified parties in connection with
any one action or related actions in the same jurisdiction arising out of the
same general allegations or circumstances unless any such indemnified party
shall have been advised by such counsel that there may be one or more legal
defenses available to it which are different from or additional to or in
conflict with those available to the other indemnified parties and in the
judgment of such counsel it is advisable for such indemnified party to employ
separate counsel. An indemnifying party will not, without the prior written
consent of the indemnified party, settle or compromise or consent to the entry
of any judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
(i) 


                                      -23-
<PAGE>   24

includes an unconditional release of each 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 is
unavailable or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above, then each indemnifying party shall contribute to
the amount paid or payable by such indemnifying party as a result of the losses,
claims, damages or liabilities referred to in subsection (a) or (b) above (i) in
such proportion as is appropriate to reflect the relative benefits received by
the Seller on the one hand and the Underwriters on the other from the offering
of the Notes or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Seller on the one hand and the Underwriters on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities as well as any other relevant equitable
considerations. The relative benefits received by the Seller on the one hand and
the Underwriters on the other shall be deemed to be in the same proportion as
the total net proceeds from the offering (before deducting expenses) received by
the Seller bear to the total underwriting discounts and commissions received by
the 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 Seller or by the Underwriters and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such untrue statement or omission. The Company 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 referred to in
the first sentence of 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 action or claim which is the subject of this
subsection (d). 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 Certificates 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, except
as may be provided in any agreement among the Underwriters relating to the
offering of the Certificates. 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 in this subsection (d) to
contribute are several in proportion their respective underwriting obligations
and not joint.

                  (e) The obligations of the Seller under this Section shall be
in addition to any liability which the Seller 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 shall be in addition to any liability 


                                      -24-

which the respective Underwriters may otherwise have and shall extend, upon the
same terms and conditions, to each director of the Seller, to each officer of
the Seller who has signed the Registration Statement and to each person, if any,
who controls the Seller within the meaning of the Act.

                8. Survival of Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of the
Seller or its officers and of the several Underwriters set forth in or made
pursuant to this Agreement or contained in certificates of officers of the
Seller submitted pursuant hereto shall remain operative and in full force and
effect, regardless of any investigation or statement as to the results thereof,
made by or on behalf of any Underwriter, the Seller or any of their respective
representatives, officers or directors or any controlling person, and will
survive delivery of and payment for the Certificates. If for any reason the
purchase of the Certificates by the Underwriters is not consummated, the Seller
shall remain responsible for the expenses to be paid or reimbursed by the Seller
pursuant to Section 5 and the respective obligations of the Seller and the
Underwriters pursuant to Section 7 shall remain in effect. If for any reason the
purchase of the Certificates by the Underwriters is not consummated (other than
pursuant to Section 9), the Seller will reimburse the Underwriters for all
out-of-pocket expenses (including fees and disbursements of counsel) reasonably
incurred by them in connection with the offering of the Certificates.

                  9. Failure to Purchase the Certificates. If any Underwriter or
Underwriters default in their obligations to purchase its portion of the
Certificates hereunder and the aggregate principal amount of the Certificates
that such defaulting Underwriter or Underwriters agreed but failed to purchase
does not exceed 10% of the total principal amount of the Certificates, the
Representative may make arrangements satisfactory to the Seller for the purchase
of such Certificates by other persons, including any of the Underwriters, but if
no such arrangements are made by the Closing Date, the non-defaulting
Underwriters shall be obligated severally, in proportion to their respective
commitments hereunder, to purchase the Certificates that such defaulting
Underwriters agreed but failed to purchase. If any Underwriter or Underwriters
so default and the aggregate principal amount of the Certificates with respect
to such default or defaults exceeds 10% of the total principal amount of the
Certificates and arrangements satisfactory to the Representative and the Seller
for the purchase of such Certificates by other persons are not made within 36
hours after such default, this Agreement will terminate without liability on the
part of any non-defaulting Underwriter or the Seller, except as provided in
Section 7. As used in this Agreement, the term "Underwriter" includes any person
substituted for an Underwriter under this Section. Nothing herein will relieve a
defaulting Underwriter or Underwriters from liability for its default.

               10. Notices. All communications hereunder will be in writing and,
if sent to the Underwriters, will be mailed, delivered or telegraphed and
confirmed to the Representative at 11 Madison Avenue, New York, NY 10010,
Attention: Joseph Fashano; if sent to the Seller, will be mailed, delivered or
telegraphed and confirmed to it at Key Bank USA, National Association, 800
Superior Avenue, Cleveland, OH 44144, Attention: Senior Vice President,
Education Lending; provided, however, that any notice to an Underwriter pursuant
to Section 7 will be 

                                      -25-
<PAGE>   26

mailed, delivered or telegraphed and confirmed to such Underwriter. Any such
notice will take effect at the time of receipt.

               11. Successors. This Agreement will inure to the benefit of and
be binding upon the parties hereto and their respective successors and the
officers and directors and controlling persons referred to in Section 7, and no
other person will have any right or obligations hereunder.

               12. Representation of Underwriters. The Representative shall act
for the several Underwriters in connection with this financing, and any action
under this Agreement taken by the Representative will be binding upon all the
Underwriters.

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

               14. Applicable Law. This Agreement will be governed by, and
construed in accordance with, the laws of the State of New York.

                                    The Notes

                  SECTION 2.01. Form. The Class A-1 Notes and the Class A-2
Notes, together with the Indenture Trustee's certificate of authentication,
shall be in substantially the forms set forth in Exhibits A-1 and A-2,
respectively, 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 Class A-1 Notes and the Class A-2 Notes set forth in Exhibits A-1
and A-2 are part of the terms of this Indenture.

                  SECTION 2.02. 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,

offices prior to the authentication and delivery of such Notes or did not hold
such offices at the date of such Notes.

                                      -3-
<PAGE>   10

                  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 2.03. 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 as the officers
executing such Notes may determine, as evidenced by their execution of such
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 3.02, without charge to
the holder of the Notes. 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 2.04. 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 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 will 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 holders of the Notes 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 3.02, 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 



                                      -4-
<PAGE>   11

holder of the Notes 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 holder of the Notes, Notes may be
exchanged for other Notes in any authorized denominations, a like class 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, 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 holder of the
Notes shall obtain from the Indenture Trustee, the Notes which the holder of the
Notes 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.

                  The Issuer initially appoints The Depository Trust Company
("DTC") to act as depositary (the "Depositary") with respect to the Note(s).

                  The Issuer initially appoints the Indenture Trustee to act as
custodian with respect to the Notes.

                  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 holder of the Notes thereof or such holder'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 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 holder of the Notes 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 2.03 or 9.06 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 2.05. 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 Indenture Trustee such security
or indemnity as may be required by it 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 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 holder of the Notes 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 2.06. 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 Noteholders' Interest Index Carryover), if any, on such Note and for all
other 



                                      -6-
<PAGE>   13

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 2.07. Payment of Principal and Interest; Defaulted
Interest; Noteholders' Interest Index Carryover. (a) The Class A-1 Notes and the
Class A-2 Notes shall accrue interest as provided in the forms of the Class A-1
Note and the Class A-2 Note set forth in Exhibits A-1 and A-2 respectively, and
such interest shall be payable on each Distribution Date as specified therein,
subject to Section 3.01. Any installment of interest (and any Noteholders'
Interest Index Carryover) or principal, if any, payable on any Note which is
punctually paid or duly provided for by the Issuer on the applicable
Distribution Date shall be paid to the Person in whose name such Note (or one or
more Predecessor Notes) is registered on the Record Date by check mailed
first-class, postage prepaid to such Person's address as it appears on the Note
Register on such Record Date, except that, unless Definitive Notes have been
issued pursuant to Section 2.12, with respect to Notes registered on the Record
Date in the name of the nominee of the Clearing Agency (initially, such nominee
to be Cede & Co.), payment will be made by wire transfer in immediately
available funds to the account designated by such nominee and except for the
final installment of principal payable with respect to such Note on a
Distribution Date or on the applicable Note Final Maturity Date which shall be
payable as provided below. The funds represented by any such checks returned
undelivered shall be held in accordance with Section 3.03.

                  (b) The principal of each Note shall be payable in
installments on each Distribution Date as provided in the form of the Class A-1
Note and the Class A-2 Note set forth in Exhibits A-1 and A-2, respectively.
Notwithstanding the foregoing, the entire unpaid principal amount of the Notes
shall be due and payable, if not previously paid, on the date on which an Event
of Default shall have occurred and be continuing, if the Indenture Trustee or
the holders 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 5.02. All principal payments on
each class of Notes shall be made pro rata to the holders of the Notes 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 Noteholders' Interest Index Carryover for
such Notes) 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 the holders of the Notes as provided in
Section 10.02.

                  (c) If the Issuer defaults in a payment of interest on the
Notes, the Issuer shall pay defaulted interest (plus interest on such defaulted
interest to the extent lawful) at the applicable Note Interest Rate in any
lawful manner. The Issuer may pay such defaulted interest 



                                      -7-
<PAGE>   14

to the persons who are holders of the Notes on a subsequent special record date,
which date shall be at least five Business Days prior to the payment date. The
Issuer shall fix or cause to be fixed any such special record date and payment
date, and, at least 15 days before any such special record date, the Issuer
shall mail to each holder of the Notes a notice that states the special record
date, the payment date and the amount of defaulted interest to be paid.

                  (d) The Noteholders' Interest Index Carryover for each
Distribution Date (including all unpaid Noteholders' Interest Index Carryover
for such Notes for prior Distribution Dates and interest accrued thereon at the
applicable Note Interest Rate for each applicable Interest Period) shall be
payable to each class of such Notes, pro rata based on the amount of
Noteholders' Interest Index Carryover then owing on each class of such Notes, on
each Distribution Date solely to the extent of funds required and available to
be distributed to the holders of the Notes by the Indenture Trustee pursuant to
Section 5.05(c)(ix) or 5.06(e) of the Sale and Servicing Agreement. Any
Noteholders' Interest Index Carryover 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 Notes have been issued pursuant to
Section 2.12, with respect to the Notes registered on the Record Date in the
name of the nominee of the Clearing Agency (initially, such nominee to be Cede &
Co.), payment will 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 3.03.

                  SECTION 2.08. Cancellation. All Notes surrendered for payment,
registration of transfer, exchange or redemption shall, if surrendered to any
Person other than the Indenture Trustee, be delivered to the Indenture Trustee
and shall be promptly cancelled by the Indenture Trustee. The Issuer may at any
time deliver to the Indenture Trustee for cancellation any Notes previously
authenticated and delivered hereunder 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 cancelled 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 2.09. Release of Collateral. Subject to Section 11.01
and the terms of the Basic Documents, the Indenture Trustee shall release
property from the lien of this Indenture only upon receipt of an Issuer Request
accompanied by an Officers' Certificate of the Issuer, an Opinion of Counsel and
Independent Certificates in accordance with TIA Sections 314(c) and 314(d)(l) or
an Opinion of Counsel in lieu of such Independent Certificates to the effect
that the TIA does not require any such Independent Certificates.

                  SECTION 2.10. Book-Entry Notes. The Notes, upon original
issuance, will be issued in the form of typewritten Notes representing the
Book-Entry Notes, to be delivered to The Depository Trust Company, the initial
Clearing Agency, by, or on behalf of, the Issuer. Such Notes shall initially be
registered on the Note Register in the name of Cede & Co., the nominee of the
initial Clearing Agency, and no Note Owner will 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 may deal
         with the Clearing Agency for all purposes (including the payment of
         principal of and interest and other amounts on the Notes) as the
         authorized representative of the Note Owners;

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

                  (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
         Agreements. 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 the holders of the 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 holders of the Notes is required under this
Indenture, unless and until Definitive Notes shall have been issued to Note
Owners pursuant to Section 2.12, the Indenture Trustee shall give all such
notices and communications specified herein to be given to the holders of the
Notes 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 properly discharge its responsibilities with respect to the
Notes, and the Administrator is unable to locate a qualified 



                                      -9-
<PAGE>   16

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 will
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 the holders of the Notes.


                                   ARTICLE III

                                    Covenants

                  SECTION 3.01. Payment to Noteholders. The Issuer will duly and
punctually pay the principal of (subject to the parenthetical in the following
sentence), interest, if any, on and any Noteholders' Interest Index Carryover
(but only to the extent provided in Sections 2.07(d) and 8.02(c)) with respect
to each class of Notes in accordance with the terms of such Notes and this
Indenture. Without limiting the foregoing, subject to Section 8.02(c), the
Issuer will cause to be distributed to the holders of the Class A-1 Notes and to
the holders of the Class A-2 Notes 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), to which the holders of the Notes are entitled to receive
pursuant to the Sale and Servicing Agreement. Amounts properly withheld under
the Code by any Person from a payment to any holder of the Notes of interest
(including any Noteholders' Interest Index Carryover) and/or principal shall be
considered as having been paid by the Issuer to such holder of the Notes for all
purposes of this Indenture.

                  SECTION 3.02. Maintenance of Office or Agency. The Issuer will
maintain in the Borough of Manhattan, The City of New York, an office or agency
where Notes may be surrendered for registration of transfer or exchange. The
Issuer hereby initially appoints the Indenture Trustee to serve as its agent for
the foregoing purposes. The Issuer will 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 may be made 



                                      -10-
<PAGE>   17

or served at the Corporate Trust Office, and the Issuer hereby appoints the
Indenture Trustee as its agent to receive all such surrenders in respect of the
Notes.

                  SECTION 3.03. Money for Payments To Be Held in Trust. As
provided in Section 8.02(a) and (b), all payments of amounts due and payable
with respect to any Notes that are to be made from amounts distributed from the
Collection Account or any other Trust Account pursuant to Section 8.02(c) shall
be made on behalf of the Issuer by the Indenture Trustee or by another Paying
Agent, and no amounts so distributed from the Collection Account for payments of
Notes shall be paid over to the Issuer except as provided in this Section.

                  On or before the Business Day next preceding each Distribution
Date and Redemption Date, the Issuer shall distribute or cause to be distributed
to the Indenture Trustee (or any other Paying Agent) an aggregate sum sufficient
to pay the amounts then becoming due under the Notes and/or Certificates, 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 will cause each Paying Agent other than the
Indenture Trustee to execute and deliver to the Indenture Trustee an instrument
in which such Paying Agent shall agree with the Indenture Trustee (and if the
Indenture Trustee acts as Paying Agent, it hereby so agrees), subject to the
provisions of this Section, that such Paying Agent will:

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

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

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

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



                                      -11-
<PAGE>   18

         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; and the holder of the
Notes 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 the holders of the Notes 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 holder of the Notes).

                  SECTION 3.04. Existence. The Issuer will keep in full effect
its existence, rights and franchises as a trust under the laws of the State of
New York (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 will keep in full effect its existence, rights and
franchises under the laws of such other jurisdiction) and will 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 3.05. 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, instruments
of further assurance and other instruments, and will take such other action
necessary or advisable to:



                                      -12-
<PAGE>   19

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

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

                  (iii) enforce any of the Collateral; or

                  (iv) preserve and defend title to the Indenture Trust Estate
         and the rights of the Indenture Trustee and the holders of the Notes 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 3.06. 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, any
indentures supplemental hereto, and any other requisite documents, and with
respect to the execution and filing of any financing statements and continuation
statements, as are 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 April 30 in each calendar year, beginning in
2000, the Issuer shall furnish to the Indenture Trustee an Opinion of Counsel
either stating that, in the opinion of such counsel, such action has been taken
with respect to the recording, filing, re-recording and refiling of this
Indenture, any indentures supplemental hereto and any other requisite documents
and with respect to the execution and filing of any financing statements and
continuation statements as is necessary to maintain the lien and security
interest created by this Indenture and reciting 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, re-recording and refiling of this Indenture, any
indentures supplemental hereto and any other requisite documents and the
execution and filing of any financing statements and continuation statements
that will, in the opinion of such counsel, be required to maintain the lien and
security interest of this Indenture until April 30 in the following calendar
year.

                  SECTION 3.07. Performance of Obligations; Servicing of
Financed 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 



                                      -13-
<PAGE>   20

covenants or obligations under any instrument or agreement included in the
Indenture Trust Estate or that would result in the amendment, hypothecation,
subordination, termination or discharge of, or impair the validity or
effectiveness of, any such instrument or agreement, except as expressly provided
in this Indenture, the Sale and Servicing Agreement, the Supplemental Sale and
Servicing Agreement 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. Initially, the
Issuer has contracted with each Servicer and the Administrator to assist the
Issuer in performing its duties under this Indenture.

                  (c) The Issuer will punctually perform and observe all its
obligations and agreements contained in this Indenture, the other Basic
Documents and in the instruments and agreements included in the Indenture Trust
Estate, including filing or causing to be filed all UCC financing statements and
continuation statements required to be filed by the terms of this Indenture and
the Sale and Servicing 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 holders of at least a majority of the Outstanding Amount of the Notes.

                  (d) If the Issuer shall have knowledge of the occurrence of a
Servicer Default or an Administrator Default under the Sale and Servicing
Agreement, 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 a Servicer to perform any of its duties or obligations under
the Sale and Servicing Agreement or the Supplemental Sale and Servicing
Agreement, or an Administrator Default shall arise from the failure of the
Administrator to perform any of its duties or obligations under the Sale and
Servicing Agreement, the Supplemental Sale and Servicing Agreement or the
Administration Agreement, as the case may be, with respect to the Financed
Student Loans, the Issuer shall take all reasonable steps available to it to
enforce its rights under the Basic Documents in respect of such failure.

                  (e) As promptly as possible after the giving of notice of
termination to a Servicer of such Servicer's rights and powers, or to the
Administrator of the Administrator's rights and powers, pursuant to Section 8.01
of the Sale and Servicing Agreement, the Issuer shall appoint a successor
servicer (the "Successor Servicer"), or a successor administrator (the
"Successor Administrator"), and such Successor Servicer or 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
Administrator has not been appointed and accepted its appointment at the time
when a Servicer or Administrator, as the case may be, ceases to act as Servicer
or Administrator, as the case may be, the Indenture Trustee without further
action shall 



                                      -14-
<PAGE>   21

automatically be appointed a Successor Servicer or Administrator, as the case
may be. The Indenture Trustee may resign as a Servicer or the Administrator by
giving written notice of such 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
Financed 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 or a
new administrator as a Successor Servicer or Administrator under the Sale and
Servicing Agreement. Any Successor Servicer or Administrator, as the case may
be, 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 with the Issuer having substantially the same
provisions as the provisions of the Sale and Servicing Agreement and the
Supplemental Sale and Servicing Agreement applicable to the predecessor Servicer
or the provisions of the Sale and Servicing Agreement, the Supplemental Sale and
Servicing Agreement and the Administration Agreement applicable to the
Administrator. If within 30 days after the delivery of the notice referred to
above, the Issuer shall not have obtained such a new servicer or 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 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 Sale and Servicing Agreement, and in
accordance with Section 8.02 of the Sale and Servicing Agreement, the Issuer
shall enter into an agreement with such successor for the servicing or
administration of the Financed 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 a Servicer's duties with respect to Financed
Student Loans or the Administrator's duties with respect to the Issuer and the
Financed 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 a Servicer or the Administrator, as the case
may be, and the servicing or administration of the Financed Student Loans. In
case the Indenture Trustee shall become successor to a Servicer or the
Administrator, as the case may be, under the Sale and Servicing Agreement, the
Indenture Trustee shall be entitled to appoint as Servicer or as Administrator,
as the case may be, any one of its affiliates or agents, provided that such
appointment shall not affect or alter in any way the liability of the Indenture
Trustee as a successor for the performance of the duties and obligations of such
Servicer or the Administrator in accordance with the terms hereof.



                                      -15-
<PAGE>   22

                  (f) Upon any termination of a Servicer's rights and powers
pursuant to the Sale and Servicing Agreement, or any termination of the
Administrator's rights and powers pursuant to the Sale and Servicing Agreement,
as the case may be, the Issuer shall promptly notify the Indenture Trustee. As
soon as a Successor Servicer or a Successor Administrator is appointed, the
Issuer shall notify the Indenture Trustee 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 holders 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 therein, or waive timely
performance or observance by any Servicer, the Administrator, the Seller, the
Issuer or the Eligible Lender Trustee under the Sale and Servicing Agreement and
the Supplemental Sale and Servicing Agreement; 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 holders of the Notes, or (ii) reduce the aforesaid
percentage of the Notes which are required to consent to any such amendment,
without the consent of the holders of all the Outstanding Notes. If any such
amendment, modification, supplement or waiver shall be so consented to by the
Indenture Trustee or such holders of the Notes, the Issuer 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 3.08. 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 Noteholders' Interest Index
         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 holder of the
         Notes 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 



                                      -16-
<PAGE>   23

         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

the determination of the Minimum Purchase Amount, the Indenture Trustee may
consult, and, at the direction of the Seller, shall consult, with a financial
advisor (which may be the Administrator) to determine if the fair market value
of the Financed Student Loans has been offered. The proceeds of any such sale
will be applied in the order of priority set forth in Section 5.04(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 to purchase the
Financed Student Loans on future Distribution Dates upon terms similar to those
described above.

                  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



                                      -24-
<PAGE>   31

                  (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 5.03. Collection of Indebtedness and Suits for
Enforcement by Indenture Trustee. (a) The Issuer covenants that if (i) default
is made in the payment of any interest (including, subject to the limitations of
Sections 2.07(d) and 8.02(c), any Noteholders' Interest Index 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
or any installment of the principal of any Note when the same becomes due and
payable, the Issuer will, upon demand of the Indenture Trustee, pay to it, for
the benefit of the holders of the Notes, the whole amount then due and payable
on such Notes for principal and interest (and any Noteholders' Interest Index
Carryover), with interest upon the overdue principal, and, to the extent payment
at such rate of interest shall be legally enforceable, upon overdue installments
of interest (and any Noteholders' Interest Index Carryover), at the rate
specified in Section 2.07 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.

                  (b) 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.

                  (c) If an Event of Default occurs and is continuing, the
Indenture Trustee may, as more particularly provided in Section 5.04, in its
discretion, proceed to protect and enforce its rights and the rights of the
holders of the Notes, 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.

                  (d) 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



                                      -25-
<PAGE>   32

appointed for or taken possession of the Issuer or its property or such other
obligor or Person, or in case of any other comparable judicial Proceedings
relative to the Issuer or other obligor upon the Notes, or to the creditors or
property of the Issuer or such other obligor, the Indenture Trustee,
irrespective of whether the principal of any Notes shall then be due and payable
as therein expressed or by declaration or otherwise and irrespective of whether
the Indenture Trustee shall have made any demand pursuant to the provisions of
this Section, shall be entitled and empowered, by intervention in such
proceedings or otherwise:

                  (i) to file and prove a claim or claims for the whole amount
         of principal and interest (including any Noteholders' Interest Index
         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
         holders of the Notes allowed in such Proceedings;

                  (ii) unless prohibited by applicable law and regulations, to
         vote on behalf of the holders of the Notes 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 holders of the Notes 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 holders of the Notes 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 holders of the Notes 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 holders of the
Notes, 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.

                  (e) 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 holder of the Notes any plan of reorganization, arrangement,
adjustment or composition affecting the Notes or the rights 



                                      -26-
<PAGE>   33

of any holder of the Notes thereof or to authorize the Indenture Trustee to vote
in respect of the claim of any holder of the Notes in any such proceeding
except, as aforesaid, to vote for the election of a trustee in bankruptcy or
similar Person.

                  (f) 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 holders of the Notes.

                  (g) 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 holders of the Notes, and it shall
not be necessary to make any holder of the Notes a party to any such
Proceedings.

                  SECTION 5.04. Remedies; Priorities. (a) 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 5.05):

                  (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
         and take any other appropriate action to protect and enforce the rights
         and remedies of the Indenture Trustee and the holders of the Notes; and

                  (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;

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 5.01(i) or (ii), unless (i) the holders
of all outstanding Notes consent to such sale, (ii) the proceeds of such sale
are sufficient to pay in full the principal of and the accrued interest on the



                                      -27-
<PAGE>   34

outstanding Notes at the date of such sale or (iii) the Indenture Trustee
determines that the collections on the Financed Student Loans would not be
sufficient on an ongoing basis to make all payments on the Notes as such
payments would have become due if such obligations had not been declared due and
payable, and the Indenture Trustee obtains the consent of the holders of 66 2/3%
of the aggregate principal amount of the Notes then outstanding; provided,
further, that the Indenture Trustee may not sell or otherwise liquidate the
Trust Estate following an Event of Default, other than an Event of Default
described in Section 5.01(i) or (ii) unless (i) the proceeds of the sale or
liquidation of the Trust Estate distributable to the holders of the Certificates
are sufficient to pay to the holders of the Certificates the outstanding
principal balance of the Certificates plus accrued and unpaid return thereon or
(ii) after receipt of notice from the Eligible Lender Trustee that the proceeds
of such sale or liquidation distributable to the holders of the Certificates
would not be sufficient to pay to the holders of the Certificates the
outstanding principal balance of the Certificates plus accrued and unpaid return
thereon, the holders of the Certificates of at least a majority of the
outstanding principal balance of the Certificates consent thereto. In addition,
notwithstanding anything herein to the contrary, the Indenture Trustee's rights
hereunder to sell the Financed Student Loans shall be subject to the rights of
PHEAA to submit a first offer therefor in accordance with paragraph 8 of the
Supplemental Sale and Servicing Agreement.

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

                  FIRST: to the Indenture Trustee for amounts due under Section
         6.07;

                  SECOND: to the Servicers for due and unpaid Servicing Fees;

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

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

                  FIFTH: to the Issuer for distribution of principal and
         interest due and unpaid to the holders of the Certificates;

                  SIXTH: [Reserved];

                  SEVENTH: to the Servicers, for any unpaid Excess Servicing
         Fees;



                                      -28-
<PAGE>   35

                  EIGHTH: to the holders of the Notes for any unpaid
         Noteholders' Interest Index Carryover, ratably, without preference or
         priority of any kind, according to the amount of Noteholders' Interest
         Index Carryover attributable to each Note;

                  NINTH: to the Issuer for distribution to the holders of the
         Certificates for any unpaid Certificateholders' Interest Index
         Carryover; and

                  TENTH: to the Issuer, for distribution in accordance with the
         terms of the Sale and Servicing Agreement.

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

                  SECTION 5.05. Optional Preservation of the Financed Student
Loans. If the Notes have been declared to be due and payable under Section 5.02
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 holders of the Notes that there be at all times
sufficient funds for the payment of principal of and interest (including any
Noteholders' Interest Index 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 5.06. Limitation of Suits. No holder of the Notes
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 holder of the Notes has previously given written
         notice to the Indenture Trustee of a continuing Event of Default;

                  (ii) the holders 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 holder of the Notes have offered to the Indenture
         Trustee reasonable indemnity against the costs, expenses and
         liabilities to be incurred in complying with such request;



                                      -29-
<PAGE>   36

                  (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
         holders of a majority of the Outstanding Amount of the Notes;

it being understood and intended that no one or more holders of the Notes 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 holders of the Notes or to obtain or to seek to obtain priority or
preference over any other holders of the Notes 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 holders of the
Notes, 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 5.07. Unconditional Rights of Noteholders To Receive
Principal and Interest. Notwithstanding any other provisions in this Indenture,
any holder of the Notes shall have the right, which is absolute and
unconditional, to receive payment of the principal of and interest, if any, 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 holder of the Notes.

                  SECTION 5.08. Restoration of Rights and Remedies. If the
Indenture Trustee or any holder of the Notes 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 holder of the Notes, then and in every such case
the Issuer, the Indenture Trustee and the holders of the Notes 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 holders of the Notes shall continue as though no such
Proceeding had been instituted.

                  SECTION 5.09. Rights and Remedies Cumulative. No right or
remedy herein conferred upon or reserved to the Indenture Trustee or to the
holders of the Notes is intended to be exclusive of any other right or remedy,
and every right and remedy shall, to the extent permitted by law, be cumulative
and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.



                                      -30-
<PAGE>   37

                  SECTION 5.10. Delay or Omission Not a Waiver. No delay or
omission of the Indenture Trustee or any holder of the Notes 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 holders of the Notes may be exercised from time to time, and as often as
may be deemed expedient, by the Indenture Trustee or by the holders of the
Notes, as the case may be.

                  SECTION 5.11. Control by Noteholders. The holders 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 5.04, any
         direction to the Indenture Trustee to sell or liquidate the Indenture
         Trust Estate shall be by the holders of not less than 100% of the
         Outstanding Amount of the Notes;

                  (iii) if the conditions set forth in Section 5.05 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 holders 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 6.01, the Indenture Trustee need not
take any action that it determines might involve it in liability or might
materially adversely affect the rights of (i) any holders of the Notes not
consenting to such action.

                  SECTION 5.12. Waiver of Past Defaults. Prior to the time a
judgment or decree for payment of money due has been obtained as described in
Section 5.02, the holders 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 2.07(d) and 8.02(c), any Noteholders' Interest Index
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 holder of
the Notes. In the case of any such waiver, the Issuer, the Indenture Trustee and
the holders of the Notes 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.



                                      -31-
<PAGE>   38

                  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 holder of the Notes 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 holder of the Notes, or
group of holders of the Notes, in each case holding in the aggregate more than
10% of the Outstanding Amount of the Notes or (c) any suit instituted by any
holder of the Notes for the enforcement of the payment of principal of or
interest (including any Noteholders' Interest Index 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 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 holders of the Notes 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 5.04(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 Administrator and the 



                                      -32-
<PAGE>   39

Servicers, as applicable, of each of their obligations to the Issuer under or in
connection with the Sale and Servicing Agreement and the Supplemental Sale and
Servicing Agreement (and with respect to the Administrator only, the
Administration Agreement) 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 and Servicing Agreement and the
Supplemental Sale and Servicing Agreement (and the Administration Agreement) 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 Administrator
or a Servicer thereunder and the institution of legal or administrative actions
or proceedings to compel or secure performance by the Seller, the Administrator
or the Servicers of each of their obligations under the Sale and Servicing
Agreement and the Supplemental Sale and Servicing Agreement (and the
Administration Agreement).

                  (b) If an Event of Default has occurred and is continuing, the
Indenture Trustee may, and at the direction (which direction shall be in writing
or by telephone (confirmed in writing promptly thereafter)) of the holders 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
Administrator or any Servicer under or in connection with the Sale and Servicing
Agreement and the Supplemental Sale and Servicing Agreement (and the
Administration Agreement), including the right or power to take any action to
compel or secure performance or observance by the Seller, the Administrator or
the Servicers of each of their obligations to the Issuer thereunder and to give
any consent, request, notice, direction, approval, extension or waiver under the
Sale and Servicing Agreement and the Supplemental Sale and Servicing Agreement
(and the Administration Agreement) and any right of the Issuer to take such
action shall be suspended.


                                   ARTICLE VI

                              The Indenture Trustee

                  SECTION 6.01. 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 of 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 



                                      -33-
<PAGE>   40

         expressed therein, upon certificates or opinions furnished to the
         Indenture Trustee and conforming to the requirements of this Indenture;
         provided, however, that the Indenture Trustee shall examine the
         certificates and opinions to determine whether or not they conform to
         the requirements of this Indenture.

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

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

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

                  (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) Every provision of this Indenture that in any way relates
to the Indenture Trustee is subject to paragraphs (a), (b), (c) and (g) of this
Section 6.01.

                  (e) 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.

                  (f) 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 Sale and Servicing Agreement.

                  (g) 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.

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

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

<PAGE>   41

                  (j) 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 6.01.

                  (k) Notwithstanding any other provision in this Agreement or
the other Basic Documents, nothing in this Agreement or the other Basic
Documents shall be construed to limit the legal responsibility of the Indenture
Trustee to the U.S. Secretary of Education or a Guarantor for any violations of
statutory or regulatory requirements that may occur with respect to loans held
by the Indenture Trustee pursuant to, or to otherwise comply with their
obligations under, the Higher Education Act or implementing regulations, it
being expressly understood that the Indenture Trustee has no obligation or duty
pursuant to this Section except in the event of Foreclosure or pursuant to
Section 8.02 of the Sale and Servicing Agreement as a successor Servicer.

                  SECTION 6.02. Rights of Indenture Trustee. (a) 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 an Officers' Certificate of the Issuer 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.

                  (f) In the event that the Person acting as Indenture Trustee
is also acting as securities intermediary all the rights, powers, immunities and
indemnities afforded to the Indenture Trustee under the Basic Documents shall
also be afforded to the securities intermediary.

                  SECTION 6.03. Individual Rights of Indenture Trustee. The
Indenture Trustee in its individual or any other capacity may become the owner
or pledgee of Notes and may otherwise deal with the Issuer or its Affiliates
with the same rights it would have if it were not Indenture Trustee. Any Paying
Agent, Note Registrar, co-registrar or co-paying agent may do the same with like
rights. However, the Indenture Trustee must comply with Sections 6.11 and 6.12.

                  SECTION 6.04. 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 6.05. Notice of Defaults. 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 to each holder of the Notes notice of the
Default within 90 days after it occurs. Except in the case of a Default in
payment of principal of or interest (including any Noteholders' Interest Index
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 holders of the Notes.

                  SECTION 6.06. Reports by Indenture Trustee to Noteholders. The
Indenture Trustee shall deliver to each holder of the Notes (and to each Person
who was a holder of the Notes at any time during the applicable calendar year)
such information as may be required to enable such holder to prepare its Federal
and state income tax returns. Within 60 days after each December 31 beginning
with the December 31 following the date of this Indenture, the Indenture Trustee
shall mail to each holder of the Notes 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 Sections 313(a) or (b) shall, at the time of such
transmission to holders of the Notes, 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 6.07. Compensation and Indemnity. The Issuer shall
cause the Administrator to pay to the Indenture Trustee reasonable compensation
for its services in accordance with a separate agreement between the
Administrator and the Indenture Trustee and shall cause the Administrator 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. 



                                      -36-
<PAGE>   43

The Issuer shall cause the Administrator to indemnify the Indenture Trustee
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. Without
limiting the generality of the foregoing, it is expressly understood that the
foregoing indemnity, subject to the last sentence of this paragraph, shall apply
to any loss, liability or expense incurred by the Indenture Trustee under
Section 12(A) of the Supplemental Sale and Servicing Agreement. 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 the 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 or the
earlier resignation or removal of the Indenture Trustee. When the Indenture
Trustee incurs expenses after the occurrence of a Default specified in Section
5.01(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 6.08. 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 6.08. The Indenture Trustee
may resign at any time by so notifying the Issuer. The holders 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.

<PAGE>   44

                  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 the holders
of the Notes. The retiring Indenture Trustee shall promptly transfer all
property held by it as Indenture Trustee to the successor Indenture Trustee upon
payment of all monies due and owing to the retiring Indenture Trustee.

                  If a successor Indenture Trustee does not take office within
60 days after the retiring Indenture Trustee resigns or is removed, the retiring
Indenture Trustee, the Issuer or the holders of a majority in Outstanding Amount
of the Notes may petition any court of competent jurisdiction for the
appointment of a successor Indenture Trustee.

                  If the Indenture Trustee fails to comply with Section 6.11,
any holder of the Notes 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 6.07 shall continue for the benefit of the retiring Indenture Trustee.

                  SECTION 6.09. Successor Indenture Trustee by Merger. If the
Indenture Trustee consolidates with, merges or converts into, or transfers all
or substantially all its corporate trust business or assets to, another
corporation or banking association, the resulting, surviving or transferee
corporation without any further act shall be the successor Indenture Trustee;
provided that such corporation or banking association shall be otherwise
qualified and eligible under Section 6.11. The Indenture Trustee shall provide
the Rating Agencies prior written notice of any such transaction.

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



                                      -38-
<PAGE>   45

in all such cases such certificates shall have the full force which it is
anywhere in the Notes or in this Indenture provided that the certificate of the
Indenture Trustee shall have.

                  SECTION 6.10. Appointment of Co-Trustee or Separate Trustee.
(a) Notwithstanding any other provisions of this Indenture, at any time, for the
purpose of meeting any legal requirement of any jurisdiction in which any part
of the Indenture Trust Estate may at the time be located, the Indenture Trustee
shall have the power and may execute and deliver all instruments to appoint one
or more Persons to act as a co-trustee or co-trustees, or separate trustee or
separate trustees, of all or any part of the Indenture Trust Estate, and to vest
in such Person or Persons, in such capacity and for the benefit of the holders
of the Notes, 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 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 holders of the Notes of the appointment of any co-trustee or separate
trustee shall be required under Section 6.08 hereof.

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

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

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

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

                  (c) Any notice, request or other writing given to the
Indenture Trustee shall be deemed to have been given to each of the then
separate trustees and co-trustees, as effectively as if given to each of them.
Every instrument appointing any separate trustee or co-trustee shall refer to
this Indenture and the conditions of this Article VI. Each separate trustee and
co-trustee, upon its acceptance of the trusts conferred, shall be vested with
the estates or property specified in its instrument of appointment, either
jointly with the Indenture Trustee or separately, as may 



                                      -39-
<PAGE>   46

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). 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 debt rating of Baa3 or better by Moody's. 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.


                                   ARTICLE VII

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 holders of the Notes 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 7.02. Preservation of Information; Communications to
Noteholders. (a) The Indenture Trustee shall preserve, in as current a form as
is reasonably practicable, the 



                                      -40-

list furnished to it as provided in such Section 7.01 upon receipt of a new list
so furnished.

                  (b) Holders of the Notes may communicate pursuant to TIA
Section 312(b) with other holders of the Notes with respect to their rights
under this Indenture or under the Notes. Upon receipt by the Indenture Trustee
of any request by a holder of the Notes to receive a copy of the current list of
holders of the Notes (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 holders of
the Notes produced in response thereto.

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

                  (d) The Indenture Trustee shall furnish to the holders of the
Notes promptly upon receipt of a written request therefor, duplicates or copies
of all reports, notices, requests, demands, certificates, financial statements
and any other instruments furnished to the Indenture Trustee under the Basic

                  SECTION 7.03. 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 reports and of the information, documents and other reports (or

         and regulations; and

                  (iii) supply to the Indenture Trustee (and the Indenture
         Trustee shall transmit by mail to all holders of the Notes described in

                      Accounts, Disbursements and Releases

                  SECTION 8.01. 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

Indenture. The Indenture Trustee shall apply all such money received by it on
behalf of the holders of the Notes pursuant to the Sale and Servicing 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.

                  SECTION 8.02. Trust Accounts. (a) On or prior to the Closing

other Paying Agent) on behalf of the holders of the Notes as provided in

                  (c) On each Distribution Date and Redemption Date, the

<PAGE>   49

                  (i) the Noteholders' Interest Distribution Amount, to the
         holders of the Class A-1 Notes and the holders of the Class A-2 Notes
         in an amount equal to the accrued and unpaid interest on the Notes;
         provided that if there are not sufficient funds received to pay the
         entire amount of accrued and unpaid interest then due on the Notes, the
         amounts so received shall be applied to the payment of such interest on
         the Notes on a pro rata basis;

                  (ii) the Noteholders' Principal Distribution Amount, to the
         holders of the Class A-1 Notes until the Outstanding Amount of the
         Class A-1 Notes is reduced to zero, and then to the holders of the
         Class A-2 Notes until the Outstanding Amount of the Class A-2 Notes is
         reduced to zero; and

                  (iii) the Noteholders' Interest Index Carryover, if any, to
         the holders of the Class A-1 Notes and the holders of the Class A-2
         Notes; provided that if insufficient funds are received to pay the
         entire Noteholders' Interest Index Carryover then outstanding, the
         amounts so received shall be applied to the payment of such
         Noteholders' Interest Index Carryover on a pro rata basis.

                  SECTION 8.03. 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 5.01(b) of the Sale and Servicing 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 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 6.01(c), the Indenture Trustee shall
not in any way be held liable 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 5.02, or, if such Notes
shall have been declared due and payable following an Event of Default, amounts
collected or receivable from 



                                      -43-

the Indenture Trust Estate are being applied in accordance with Section 5.05 as
if there had not been such a declaration; then the Indenture Trustee shall, to
the fullest extent practicable, invest and reinvest funds in the Trust Accounts
in one or more Eligible Investments.

                  SECTION 8.04. Release of Indenture Trust Estate. (a) Subject
to the payment of its fees and expenses pursuant to Section 6.07, 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
6.07 have been paid, release any remaining portion of the Indenture Trust Estate
that secured the Notes 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 8.04(b) only upon receipt of an Issuer
Request accompanied by an Officers' Certificate of the Issuer, an Opinion of
Counsel and (if required by TIA) Independent Certificates in accordance with TIA
Sections 314(c) and 314(d)(1) and meeting the applicable requirements of
Section 11.01.

                  (c) Each holder of the Notes, by the acceptance of a Note,
acknowledges that from time to time during the Funding Period the Indenture
Trustee shall release the lien of this Indenture on those Financed Federal Loans
to be sold to the Seller and as to which the Seller will simultaneously deposit
the aggregate Purchase Amounts thereof into the Escrow Account in accordance
with, and subject to the terms and conditions of, Section 2.03 of the Sale and
Servicing Agreement, and each holder of the Notes consents to such release.

                  SECTION 8.05. 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 8.04(a), accompanied by copies of any instruments
involved, and the Indenture Trustee shall also require, except in connection
with any action contemplated by Section 8.04(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
holders of the Notes 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.

                  (vii) to modify, eliminate or add to the provisions of this

         other provisions as may be expressly required by the TIA.

                  The Indenture Trustee is hereby authorized to join in the
execution of any such supplemental indenture and to make any further appropriate
agreements and stipulations that may be therein contained.

                  (b) The Issuer and the Indenture Trustee, when authorized by
an Issuer Order, may, also without the consent of any of the holders of the
Notes but with prior notice to the Rating Agencies, enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to, or
changing in any manner or eliminating any of the provisions of, this Indenture
or of modifying in any manner the rights of the holders of the Notes under this
Indenture; provided, however, that such action shall not, as evidenced by an
Opinion of Counsel, adversely affect in any material respect the interests of
any holder of the Notes.

                  SECTION 9.02. Supplemental Indentures with Consent of
Noteholders. The Issuer and the Indenture Trustee, when authorized by an Issuer
Order, also may, with prior notice to the Rating Agencies and with the consent
of the holders of not less than a majority of the Outstanding Amount of the
Notes, by Act of such holders of the Notes delivered to the Issuer and the
Indenture Trustee, enter into an indenture or indentures supplemental hereto for
the purpose of adding any provisions to, or changing in any manner or
eliminating any of the provisions of, this Indenture or of modifying in any
manner the rights of the holders of the Notes under this Indenture; provided,
however, that no such supplemental indenture shall, without the consent of the
holder of each Outstanding Note affected thereby:

                  (i) change the date of payment of any installment of principal
         of or interest (including any Noteholders' Interest Index Carryover) on
         any Note, or reduce the principal amount thereof, the interest rate
         thereon or the Redemption Price with respect thereto, change the
         provisions of this Indenture relating to the application of collections
         on, or the proceeds of the sale of, the Indenture Trust Estate to
         payment of principal of or interest (including any Noteholders'
         Interest Index Carryover) on the Notes, or change any place of payment
         where, or the coin or currency in which, any Note or the interest
         thereon is payable, or impair the right to institute suit for the
         enforcement of the provisions of this Indenture requiring the
         application of funds available therefor, as provided in Article V, to
         the payment of any such amount due on the Notes on or after the
         respective due dates thereof (or, in the case of redemption, on or
         after the Redemption Date);

                  (ii) reduce the percentage of the Outstanding Amount of the
         Notes, the consent of the holders of the Notes of which is required for
         any such supplemental indenture, or the consent of the holders of the

         provisions of this Indenture or certain defaults hereunder and their
         consequences provided for in this Indenture;



                                      -46-

                  (iii) modify or alter the provisions of the proviso to the
         definition of the term "Outstanding";

                  (iv) reduce the percentage of the Outstanding Amount of the

                  (v) modify any provision of this Section except to increase
         any percentage specified herein or to provide that certain additional
         provisions of this Indenture or the other Basic Documents cannot be
         modified or waived without the consent of the holder of each
         Outstanding Note affected thereby;

                  (vi) modify any of the provisions of this Indenture in such
         manner as to affect the calculation of the amount of any payment of
         interest (including any Noteholders' Interest Index Carryover) or
         principal due on any Note on any Distribution Date (including the
         calculation of any of the individual components of such calculation) or
         to affect the rights of the holders of the Notes to the benefit of any
         provisions for the mandatory redemption of the Notes contained herein;
         or

                  (vii) permit the creation of any lien ranking prior to or on a
         parity with the lien of this Indenture with respect to any part of the
         Indenture Trust Estate or, except as otherwise permitted or
         contemplated herein, terminate the lien of this Indenture on any
         property at any time subject hereto or deprive any holder of any Note
         of the security provided by the lien of this Indenture.

                  It shall not be necessary for any Act of holders of the Notes
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.

                  Promptly after the execution by the Issuer and the Indenture
Trustee of any supplemental indenture pursuant to this Section, the Indenture
Trustee shall mail to the holders of the Notes to which such amendment or
supplemental indenture relates a notice prepared by the Issuer setting forth in
general terms the substance of such supplemental indenture. Any failure of the
Indenture Trustee to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental
indenture.

                  SECTION 9.03. Execution of Supplemental Indentures. In
executing, or permitting the additional trusts created by, any supplemental
indenture permitted by this Article IX or the modifications thereby of the
trusts created by this Indenture, the Indenture Trustee shall be entitled to
receive, and subject to Sections 6.01 and 6.02, shall be fully protected in
relying upon, an Opinion of Counsel stating that the execution of such
supplemental indenture is authorized or permitted by this Indenture. The
Indenture Trustee may, but shall not be obligated 



                                      -47-

to, enter into any such supplemental indenture that affects the Indenture
Trustee's own rights, duties, liabilities or immunities under this Indenture or
otherwise.

                  SECTION 9.04. Effect of Supplemental Indenture. Upon the
execution of any supplemental indenture pursuant to the provisions hereof, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith with respect to the Notes affected thereby, and the respective rights,
limitations of rights, obligations, duties, liabilities and immunities under
this Indenture of the Indenture Trustee, the Issuer and the holders of the Notes
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 9.05. Conformity with Trust Indenture Act. Every
amendment of this Indenture and every supplemental indenture executed pursuant
to this Article IX 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 9.06. 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
any matter provided for in such supplemental indenture. If the Issuer or the
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.

                  SECTION 10.01. Redemption. (a) (i) In the event that on the
Special Determination Date the Subsequent Pool Pre-Funded Amount, after giving
effect to the purchase of any Subsequent Pool Student Loans on such date is
greater than $10,000,000, each class of Notes will be redeemed in part, on a pro
rata basis, in an aggregate principal amount equal to the Noteholders'

Distribution Date. In the event that on the Special Determination Date the
Subsequent Pool Pre-Funded Amount, after giving effect to the purchase of any
Subsequent Pool Student Loans on such date, is greater than zero but less than
or equal to $10,000,000, the Class A-1 Notes will be redeemed in an amount equal
to such Subsequent Pool Pre-Funded Amount.

                  (ii) In the event that on the Distribution Date on which the
Funding Period ends (or on the Distribution Date immediately following the last
day of the Funding Period, if the Funding Period does not end on a Distribution
Date) any amount remains on deposit in the Pre-Funding Account after giving
effect to the making of all Additional Fundings during the Funding Period,
including any such Additional Fundings on such Redemption Date, the Class A-1
Notes will be redeemed until the principal amount thereof is reduced to zero,
and then the Class A-2 Notes will be redeemed in part to the extent of any
remaining funds, in each case on a pro rata basis, in an aggregate principal
amount equal to the amount then on deposit in the Pre-Funding Account.

                  (b) In the event that the assets of the Trust are sold
pursuant to Section 9.02 of the Trust Agreement, that portion of the amounts on
deposit in the Trust Accounts to be distributed to the holders of the Notes
shall be paid to the holders of the Notes up to the Outstanding Amount of the
Notes and all accrued and unpaid interest thereon and any accrued Noteholders'
Interest Index Carryover with respect thereto (but only to the extent provided
by Sections 2.07(d) and 8.02(c)). If amounts are to be paid to holders of the
Notes pursuant to this Section 10.01(b), the Servicers, the Administrator or the
Issuer shall, to the extent practicable, furnish notice of such event to the
Indenture Trustee not later than 25 days prior to the Redemption Date whereupon
all such amounts shall be payable on the Redemption Date.

                  SECTION 10.02. Form of Redemption Notice. Notice of redemption
under Section 10.01 shall be given by the Indenture Trustee by first-class mail,

business on the Record Date preceding the 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 where 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 3.02).

                  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 holder of any Note shall not
impair or affect the validity of the redemption of any other Note.

                  SECTION 10.03. 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) 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.

         securities with the Indenture Trustee that is to be made the basis for
         the release of any property or securities subject to the lien of this
         Indenture, the Issuer shall, in addition to any obligation imposed in
         Section 11.01(a) or elsewhere in this Indenture, furnish to the
         Indenture Trustee an 



                                      -50-
<PAGE>   57

         Officers' Certificate of the Issuer certifying or stating the opinion
         of each person signing such certificate as to the fair value (within 90
         days of such deposit) to the Issuer of the Collateral or other property
         or securities to be so deposited.

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

                  (iii) Other than any property released as contemplated by
         clause (v) below, whenever any property or securities are to be
         released from the lien of this Indenture, the Issuer shall also furnish
         to the Indenture Trustee an Officers' Certificate of the Issuer
         certifying or stating the opinion of each person signing such
         certificate as to the fair value (within 90 days of such release) of
         the property or securities proposed to be released and stating that in
         the opinion of such person the proposed release will not impair the
         security under this Indenture in contravention of the provisions
         hereof.

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

                  (v) Notwithstanding Section 2.09 or any other provision of
         this Section, the Issuer may, without compliance with the requirements
         of the other provisions of this Section, (A) collect, liquidate, sell
         or otherwise dispose of Financed Student Loans as and to the extent
         permitted or required by the Basic Documents, (B) make cash payments
         out of the Trust Accounts as and to the extent permitted or required by
         the Basic Documents and (C) convey to the Seller, in order to allow the
         Seller to make Consolidation Loans, those specified Financed Student
         Loans as and to the extent permitted or required by and 



                                      -51-
<PAGE>   58

         in accordance with Section 8.04(c) hereof and Section 2.03 of the Sale
         and Servicing Agreement, so long as the Issuer shall deliver to the
         Indenture Trustee every six months, commencing April 1, 1999, an
         Officers' Certificate of the Issuer stating that all the dispositions
         of Collateral described in clauses (A), (B) or (C) above that occurred
         during the immediately preceding six calendar months were in the
         ordinary course of the Issuer's business and that the proceeds thereof
         were applied in accordance with the Basic Documents.

                  SECTION 11.02. 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
any Servicer, the Seller, the Issuer or the Administrator, stating that the
information with respect to such factual matters is in the possession of such
Servicer, the Seller, the Issuer or the Administrator, unless such counsel
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to such matters are erroneous.

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

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

                  SECTION 11.03. 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 holders of the Notes may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed
by such holders of the Notes 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 holders of the
Notes 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 6.01) 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 holder of any Notes shall bind the holder
of every Note issued upon the registration 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 11.04. Notices, etc., to Indenture Trustee, Issuer and
Rating Agencies. Any request, demand, authorization, direction, notice, consent,
waiver or Act of holders of the Notes 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 holders of the Notes
is to be made upon, given or furnished to or filed with:

                  (a) the Indenture Trustee by any holder of the Notes 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 holder of
         the Notes shall be sufficient for every purpose hereunder if in writing
         and mailed, first-class, postage prepaid, to the Issuer addressed to:
         KeyCorp Student Loan Trust 1999-A, in care of The First National Bank
         of Chicago, One First National Plaza, Suite 0126, Chicago, Illinois
         60670, Attention: Corporate Trust Administration; with a copy to the
         Administrator, 800 Superior Avenue, Fourth Floor, Cleveland, Ohio
         44114, Attention: KeyCorp Education Resources, KeyCorp Student Loan
         Trust 1999-A, or at any other address previously furnished in writing
         to the Indenture Trustee by the Issuer or the Administrator. The 



                                      -53-
<PAGE>   60

         Issuer shall promptly transmit any notice received by it from the
         holders of the Notes 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
Investors Service, Inc., 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 Rating Services, 25 Broadway (20th Floor), New York, New York
10004, Attention of Asset Backed Surveillance Department; and (iii) Fitch IBCA,
Inc., Municipal Structured Finance Group, One State Street Plaza, New York, New
York, 10004; or as to each of the foregoing, at such other address as shall be
designated by written notice to the other parties.

                  SECTION 11.05. Notices to Noteholders; Waiver. Where this
Indenture provides for notice to holders of the Notes 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 holder of the Notes
affected by such event, at his address as it appears on the Note Register, not
later than the latest date, and not earlier than the earliest date, prescribed
for the giving of such notice. In any case where notice to holders of the Notes
is given by mail, neither the failure to mail such notice nor any defect in any
notice so mailed to any particular holder of the Notes shall affect the
sufficiency of such notice with respect to other holders of the Notes, 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 holders of the Notes 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 holders of the Notes 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 11.06. 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 holder of the Notes
providing for a method of payment, or notice by the 



                                      -54-
<PAGE>   61

Indenture Trustee or any Paying Agent to such holder of the Notes, 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 11.07. Conflict with Trust Indenture Act. If any
provision hereof limits, qualifies or conflicts with another provision hereof
that is required to be included in this Indenture by any of the provisions of
the Trust Indenture Act, such required provision shall control.

                  The provisions of TIA 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 11.08. 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 11.09. Successors and Assigns. All covenants and
agreements in this Indenture and the Notes by the Issuer shall bind its
successors 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 holders of the
Notes, 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 



                                      -55-
<PAGE>   62

provisions, and the obligations, rights and remedies of the parties hereunder
shall be determined in accordance with such laws.

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

                  SECTION 11.15. Recording of Indenture. If this Indenture is
subject to recording in any appropriate public recording offices, such recording
is to be effected by the Issuer and at its expense accompanied by an Opinion of
Counsel (which may be counsel to the Indenture Trustee or any other counsel
reasonably acceptable to the Indenture Trustee) to the effect that such
recording is necessary either for the protection of the holders of the Notes 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, any 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
Seller, the Administrator, any Servicer, the Indenture Trustee or the Eligible
Lender Trustee in its individual capacity or (ii) any partner, owner,
beneficiary, agent, officer, director, employee or agent of the Seller, the
Administrator, any Servicer, 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 of the Seller, the Administrator, any Servicer, the
Indenture Trustee or the Eligible Lender Trustee 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 holder of the Notes, by accepting a Note, hereby
covenant and agree that they 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, this Indenture or any of the other Basic Documents.



                                      -56-
<PAGE>   63

                  SECTION 11.18. Inspection. The Issuer agrees that, on
reasonable prior notice, it will 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.

                                [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 Asset Backed Notes (herein
called the "Class A-1 Notes"), all issued under 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 holders of the Notes. The Class A-1 Notes are subject
to all terms of the Indenture. Capitalized but undefined terms shall have the
meanings set forth in the Indenture dated as of January 1, 1999 between KeyCorp
Student Loan Trust 1999-A and Bankers Trust Company as Trustee including
Appendix A to the Indenture.

                  The Class A-1 Notes and the Issuer's Floating Rate Class A-2
Asset Backed Notes (the "Class A-2 Notes" and, with the Class A-1 Notes, the
"Notes") are and will be equally and ratably secured by the collateral pledged
as security therefor as provided in the Indenture.

                  Principal of the Notes will be payable on each Distribution
Date to the extent set forth in the Sale and Servicing Agreement and the
Indenture. "Distribution Date" means the twenty-seventh day of each March, June,
September and December, or, if any such date is not a Business Day, the next
succeeding Business Day, commencing June 28, 1999.

                  As described on the face hereof, the entire unpaid principal
amount of this Note shall be due and payable on its Final 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 holders of the
Notes 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 5.02 of the Indenture. All principal payments on the
Notes of the same class shall be made pro rata to the holders of such Notes
entitled thereto.

                  Interest on the Notes will be payable on each Distribution
Date on the principal amount outstanding of each class of Notes until the
principal amount thereof is paid in full, at a rate per annum equal to the Note
Interest Rate for such class of Notes.

                  The "Note Interest Rate" means, with respect to any Interest
Period, (x) in the case of the Class A-1 Notes, the interest rate per annum
(computed on the basis of the actual number of days elapsed in the related
Interest Period divided by 360) equal to the lesser of (i) Three-Month LIBOR
plus 0.14% and (ii) the Student Loan Rate for such Interest Period, (y) in the
case of the Class A-2 Notes, the interest rate per annum (computed on the basis
of the actual number of days elapsed in the related Interest Period divided by
360) equal to the lesser of (i) Three-Month LIBOR plus 0.33% and (ii) the
Student Loan Rate for such Interest Period.



                                     A-1-4
<PAGE>   119

                  The "Student Loan Rate" means for any class of Securities for
any Interest Period will equal the product of (a) the quotient obtained by
dividing (i) 365 (or 366 in a leap year) by (ii) the actual number of days
elapsed in such Interest 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 Interest Period less the Servicing Fees and
the Administration Fee payable on the related Distribution Date and any
Servicing Fees paid on the two preceding Monthly Servicing Payment Dates during
the related Collection Period and (ii) the denominator of which is the
outstanding principal balance of the Securities as of the first day of such
Interest Period.

                  Pursuant to the Sale and Servicing Agreement, the
Administrator shall determine the Three-Month LIBOR for purposes of calculating
the Note Interest Rates for each given Interest Period. "Three-Month LIBOR"
means the London interbank offered rate for deposits in U.S. dollars having a
maturity of three months commencing on the related LIBOR Determination Date (the
"Index Maturity") which appears on Telerate Page 3750 as of 11:00 a.m., London
time, on such LIBOR Determination Date. If such rate does not appear on Telerate
Page 3750, the rate for that day will be determined on the basis of the rates at
which deposits in U.S. dollars, having the Index Maturity and in a principal
amount of not less than U.S. $1,000,000, are offered at approximately 11:00
a.m., London time, on such LIBOR Determination Date to prime banks in the London
interbank market by the Reference Banks. The Administrator will request the
principal London office of each of such Reference Banks to provide a quotation
of its rate. If at least two such quotations are provided, the rate for that day
will be the arithmetic mean of the quotations. If fewer than two quotations are
provided, the rate for that day will be the arithmetic mean of the rates quoted
by major banks in New York City, selected by the Administrator, at approximately
11:00 a.m., New York City time, on such LIBOR Determination Date for loans in
the U.S. dollars to leading European banks having the Index Maturity and in a
principal amount equal to an amount of not less than U.S. $1,000,000; provided
that if the banks selected as aforesaid are not quoting as mentioned in this
sentence, Three-Month LIBOR in effect for the applicable Interest Period will be
Three-Month LIBOR in effect for the previous Interest Period. For purposes of
calculating Three-Month LIBOR, a Business Day is any day on which banks in
London and New York City are open for the transaction of business. Interest due
for any Interest Period will be determined based on the actual number of days in
such Interest Period over a 360 day year.

                  "Reference Bank" means a leading bank (i) engaged in
transactions in Eurodollar deposits in the international Eurocurrency market,
(ii) not controlling, controlled by or under common control with the
Administrator and (iii) having an established place of business in London.

                  "LIBOR" Determination Date" means (x) with respect to each
Interest Period other than the initial Interest Period, the second Business Day
prior to the commencement of such Interest Period and (y) with respect to the
initial Interest Period, as determined pursuant to clause (x) for the period
from the Closing Date to but 



                                     A-1-5
<PAGE>   120

excluding March 29, 1999 and as determined on the second Business Day prior to
March 29, 1999 for the period from March 29, 1999 to but excluding June 28,
1999. For purposes of this definition, a "Business Day" is any day on which
banks in London and New York City are open for the transaction of business.

                  Any Noteholders' Interest Index Carryover that may exist on
any Distribution Date attributable to each class of Notes shall be payable to
the holders of such classes of Notes on a pro rata basis, based on the amount of
Noteholders' Interest Index Carryover then owing on each class of Notes, on that
Distribution Date and any succeeding Distribution Dates solely out of the funds
available and required to be applied thereto pursuant to the Sale and Servicing
Agreement.

                  Payments of interest on this Note due and payable 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 will 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, will notify the
Person who was the Noteholder hereof as of the Record Date preceding such
Distribution Date by notice mailed no later than five days prior to such
Distribution Date and the amount then due and payable shall be payable only upon
presentation and surrender of this Note at the Indenture Trustee's Corporate
Trust Office or at the office of the Indenture Trustee's agent appointed for
such purposes located in the Borough of Manhattan, The City of New York.

                  The Issuer shall pay interest on overdue installments of
interest at the Note Interest Rate for this Note to the extent lawful.

                  As provided in the Indenture, the Class A-1 Notes may be
redeemed in part, on a pro rata basis among all the holders of such Notes, on
the Distribution Date on which the Funding Period ends (or on the Distribution
Date immediately following the last day of the Funding Period, if the Funding
Period does not end on a Distribution Date) in the event that any amounts remain
on deposit in the Pre-Funding Account after giving 



                                     A-1-6
<PAGE>   121

effect to all Additional Fundings, including any occurring on such Distribution
Date.

                  As provided in the Indenture, if as of the Special
Determination Date, the Subsequent Pool Pre-Funded Amount is greater than
$10,000,000, such amount will be distributed on the first Distribution Date
thereafter to redeem each class of Notes and prepay the Certificates on a pro
rata basis, based on the initial principal balance of each class of Notes and
the Initial Certificate Balance; if such amount is $10,000,000 or less, it will
be distributed on such Distribution Date only to the holders of the Class A-1
Notes to redeem such Class A-1 Notes.

                  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 will 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 holder of the Notes 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, 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 of a beneficial interest in the Issuer, the Eligible Lender
Trustee or the Indenture Trustee, except as any such Person may have expressly
agreed 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 holder of the Notes 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 that such holder of
the Notes or Note Owner will 



                                     A-1-7

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 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 holders of the Notes 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, The First National Bank of Chicago 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 holder of the Notes
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 holder of
the Notes shall have no claim against any of

                                [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 Asset Backed Notes (herein
called the "Class A-2 Notes"), all issued under 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 holders of the Notes. The Class A-2 Notes are subject
to all terms of the Indenture. Capitalized but undefined terms shall have the
meanings set forth in the Indenture dated as of January 1, 1999 between KeyCorp
Student Loan Trust 1999-A and Bankers Trust Company as Trustee including
Appendix A to the Indenture.

                  The Class A-2 Notes and the Issuer's Floating Rate Class A-1
Asset Backed Notes (the "Class A-1 Notes" and, with the Class A-2 Notes, the
"Notes") are and will be equally and ratably secured by the collateral pledged
as security therefor as provided in the Indenture.

                  Principal of the Notes will be payable on each Distribution
Date to the extent set forth in the Sale and Servicing Agreement and the
Indenture. "Distribution Date" means the twenty-seventh day of each March, June,
September and December, or, if any such date is not a Business Day, the next
succeeding Business Day, commencing June 28, 1999.

                  As described on the face hereof, the entire unpaid principal
amount of this Note shall be due and payable on its Final 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 holders of the
Notes 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 5.02 of the Indenture. All principal payments on the
Notes of the same class shall be made pro rata to the holders of such Notes
entitled thereto.

                  Interest on the Notes will be payable on each Distribution
Date on the principal amount outstanding of each class of Notes until the
principal amount thereof is paid in full, at a rate per annum equal to the Note
Interest Rate for such class of Notes.

                  The "Note Interest Rate" means, with respect to any Interest
Period, (x) in the case of the Class A-1 Notes, the interest rate per annum
(computed on the basis of the actual number of days elapsed in the related
Interest Period divided by 360) equal to the lesser of (i) Three-Month LIBOR
plus 0.14% and (ii) the Student Loan Rate for such Interest Period, (y) in the
case of the Class A-2 Notes, the interest rate per annum (computed on the basis
of the actual number of days elapsed in the related Interest Period divided by
360) equal to the lesser of (i) Three Monthly LIBOR plus 0.33% and (ii) the
Student Loan Rate for such Interest Period.

                  The "Student Loan Rate" means for any class of Securities for
any Interest Period will equal the product of (a) the quotient obtained by
dividing (i) 365 (or 366 in a leap year) by (ii) the actual number of days
elapsed in such Interest 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 Interest Period less the Servicing Fees and
the Administration Fee payable on the related Distribution Date and any
Servicing Fees paid on the two preceding Monthly Servicing Payment Dates during
the related Collection Period and (ii) the denominator of which is the
outstanding principal balance of the Securities as of the first day of such
Interest Period.

                  Pursuant to the Sale and Servicing Agreement, the
Administrator shall determine the Three-Month LIBOR for purposes of calculating
the Note Interest Rates for each given Interest Period. "Three-Month LIBOR"
means the London interbank offered rate for deposits in U.S. dollars having a
maturity of three months commencing on the related LIBOR Determination Date (the
"Index Maturity") which appears on Telerate Page 3750 as of 11:00 a.m., London
time, on such LIBOR Determination Date. If such rate does not appear on Telerate
Page 3750, the rate for that day will be determined on the basis of the rates at
which deposits in U.S. dollars, having the Index Maturity and in a principal
amount of not less than U.S. $1,000,000, are offered at approximately 11:00
a.m., London time, on such LIBOR Determination Date to prime banks in the London
interbank market by the Reference Banks. The Administrator will request the
principal London office of each of such Reference Banks to provide a quotation
of its rate. If at least two such quotations are provided, the rate for that day
will be the arithmetic mean of the quotations. If fewer than two quotations are
provided, the rate for that day will be the arithmetic mean of the rates quoted
by major banks in New York City, selected by the Administrator, at approximately
11:00 a.m., New York City time, on such LIBOR Determination Date for loans in
the U.S. dollars to leading European banks having the Index Maturity and in a
principal amount equal to an amount of not less than U.S. $1,000,000; provided
that if the banks selected as aforesaid are not quoting as mentioned in this
sentence, Three-Month LIBOR in effect for the applicable Interest Period will be
Three-Month LIBOR in effect for the previous Interest Period.

                  "Reference Bank" means a leading bank (i) engaged in
transactions in Eurodollar deposits in the international Eurocurrency market,
(ii) not controlling, controlled by or under common control with the
Administrator and (iii) having an established place of business in London.

                  "LIBOR" Determination Date" means (x) with respect to each
Interest Period other than the initial Interest Period, the second Business Day
prior to the commencement of such Interest Period and (y) with respect to the
initial Interest Period, as determined pursuant to clause (x) for the period
from the Closing Date to but excluding March 29, 1999 and as determined on the
second Business Day prior to March 29, 1999 for the period from March 29, 1999
to but excluding June 28, 1999. For 



                                     A-4-5
<PAGE>   130

purposes of this definition, a "Business Day" is any day on which Banks in
London and New York City are open for the transaction of business.

                  Any Noteholders' Interest Index Carryover that may exist on
any Distribution Date attributable to each class of Notes shall be payable to
the holders of such classes of Notes on a pro rata basis, based on the amount of
Noteholders' Interest Index Carryover then owing on each class of Notes, on that
Distribution Date and any succeeding Distribution Dates solely out of the funds
available and required to be applied thereto pursuant to the Sale and Servicing
Agreement.

                  Payments of interest on this Note due and payable 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 will 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, will notify the
Person who was the Noteholder hereof as of the Record Date preceding such
Distribution Date by notice mailed no later than five days prior to such
Distribution Date and the amount then due and payable shall be payable only upon
presentation and surrender of this Note at the Indenture Trustee's Corporate
Trust Office or at the office of the Indenture Trustee's agent appointed for
such purposes located in the Borough of Manhattan, The City of New York.

                  The Issuer shall pay interest on overdue installments of
interest at the Note Interest Rate for this Note to the extent lawful.

                  As provided in the Indenture, if as of the Special
Determination Date, the Subsequent Pool Pre-Funded Amount is greater than
$10,000,000, such amount will be distributed on the first Distribution Date
thereafter to redeem each class of Notes and prepay the Certificates on a pro
rata basis, based on the initial principal balance of each class of Notes and
the Initial Certificate Balance; if such amount is $10,000,000 or less, it will
be distributed on such Distribution Date only to the holders of the Class A-1
Notes to redeem such Class A-1 Notes.

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 holder of the Notes 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, 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 of a beneficial interest in the Issuer, the Eligible Lender
Trustee or the Indenture Trustee, except as any such Person may have expressly
agreed 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 holder of the Notes 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 that such holder of
the Notes 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 



                                     A-4-7

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 term "Issuer" as used in this Note includes any successor

                  The Issuer is permitted by the Indenture, under certain

Trustee and the holders of the Notes under the Indenture.

                  The Notes are issuable only in registered form in

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, The First National Bank of Chicago 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

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 Indenture or in this Note.

                  WHEREAS, in connection therewith, the Depositor and the
Eligible Lender Trustee agree that the terms and provisions of the Original

Payments accruing during any period prior to the Cutoff Date).

                  NOW, THEREFORE, the Depositor and the Eligible Lender Trustee
hereby agree as follows:


                                    ARTICLE I

                              Definitions and Usage
                              ---------------------

                  Capitalized terms used but not defined herein are defined in
Appendix A to the Sale and Servicing Agreement, which also contains rules as to
construction and usage that shall be applicable herein.


                                   ARTICLE II

                                  Organization
                                  ------------

                  SECTION 2.01. Name. The Trust created under the Original Trust

the Trust, make and execute contracts and other instruments on behalf of the
Trust and sue and be sued.


<PAGE>   7

                  SECTION 2.02. Office. The office of the Trust shall be in care
of the Eligible Lender Trustee at its Corporate Trust Office or at such other
address as the Eligible Lender Trustee may designate by written notice to the
holders of the Trust Certificates and the Depositor.

                  SECTION 2.03. Purposes and Powers. The purpose of the Trust is
to engage in the following activities:

                 (i) to issue the Notes pursuant to the Indenture and the Trust
         Certificates pursuant to this Agreement and to sell the Notes and the
         Trust Certificates in one or more transactions;

                (ii) with the proceeds of the sale of the Notes and the Trust
         Certificates, to purchase the Financed Student Loans and to fund the
         Pre-Funding Account pursuant to the Sale and Servicing Agreement;

               (iii) to assign, grant, transfer, pledge, mortgage and convey the
         Trust Estate pursuant to the Indenture and to hold, manage and
         distribute to the holders of the Trust Certificates pursuant to the
         terms of the Sale and Servicing Agreement any portion of the Trust
         Estate released from the Lien of, and remitted to the Trust pursuant
         to, the Indenture;

                (iv) to enter into and perform its obligations under the Basic
         Documents to which it is to be a party;

                 (v) to engage in those activities, including entering into
         agreements, that are necessary, suitable or convenient to accomplish
         the foregoing or are incidental thereto or connected therewith; and

                (vi) subject to compliance with the Basic Documents, to engage
         in such other activities as may be required in connection with
         conservation of the Trust Estate and the making of distributions to the
         holders of the Trust Certificates, the holders of the Notes and the
         others specified in Section 5.05 of the Sale and Servicing Agreement.

The Trust shall not engage in any activity other than in connection with the
foregoing or other than as required or authorized by the terms of this Agreement
or the other Basic Documents.

                  SECTION 2.04. Appointment of Eligible Lender Trustee. The
Depositor hereby appoints the Eligible Lender Trustee as trustee of the Trust
effective as of the date hereof, to have all the rights, powers and duties set
forth herein.

                  SECTION 2.05. Initial Capital Contribution of Trust Estate.
Pursuant to the Original Trust Agreement, the Depositor has sold, assigned,
transferred, conveyed and set over to the Eligible Lender Trustee, as of the
date thereof, the sum of $1.00. The Eligible Lender Trustee hereby acknowledges
receipt in trust from the Depositor, as of the date thereof, of the foregoing
contribution, which shall constitute the initial Trust Estate and shall be
deposited in the 


                                      -2-
<PAGE>   8

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 the Eligible Lender Trustee for any such expenses
paid by the Eligible Lender Trustee.

                  SECTION 2.06. Declaration of Trust. The Eligible Lender
Trustee hereby declares that it will hold the Trust Estate in trust upon and
subject to the conditions set forth herein for the use and benefit of the
holders of the Trust Certificates, subject to the obligations of the Trust under
the other Basic Documents. It is the intention of the parties hereto that the
Trust constitute a trust under New York law and that this Agreement constitute
the governing instrument of such trust. It is the intention of the parties
hereto that, solely for income and franchise tax purposes, the Trust shall be
treated as a partnership, with the assets of the partnership being the Financed
Student Loans and other assets held by the Trust, the partners of the
partnership being the holders of the Trust Certificates (including the Depositor
in its capacity 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 2.07. Liability of the Certificateholders. (a) The
Depositor shall be liable directly to and will indemnify the injured party for
all losses, claims, damages, liabilities and expenses of the Trust (including
Expenses, to the extent 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 holder of the Trust Certificates or a Certificate Owner in
the capacity of an investor in the Trust Certificates or a holder of the Notes
or a Note Owner in the capacity of an investor in the Notes. In addition, any
third party creditors of the Trust (other than in connection with the
obligations described in the preceding sentence for which the Depositor shall
not be liable) shall be deemed third party beneficiaries of this paragraph. The
obligations of the Depositor under this paragraph shall be evidenced by the
Trust Certificates described in Section 3.10, which shall be deemed to be
separate classes of Trust Certificates from all other Trust Certificates issued
by the Trust; provided that the rights and obligations evidenced by all Trust
Certificates, regardless of class, except as provided in this Section, shall be
identical.

                  (b) No holder of a Trust Certificate, other than to the extent
set forth in paragraph (a), shall have any personal liability for any liability
or obligation of the Trust.

                  SECTION 2.08. Title to Trust Property. Legal title to all 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
Financed Student Loans shall be vested at all times in the Eligible Lender
Trustee on behalf of the Trust.

                  SECTION 2.09. Representations and Warranties of the Depositor.
The Depositor hereby represents and warrants to the Eligible Lender Trustee
that:

                  (a) The Depositor is duly organized and validly existing as a
         national banking association in good standing under the laws of the
         United States of America, with power and authority to own its
         properties and to conduct its business as such properties are currently
         owned and such business is presently conducted.

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

                  (c) This Agreement constitutes a legal, valid and binding
         obligation of the Depositor enforceable in accordance with its terms,
         subject to applicable bankruptcy, insolvency, reorganization and
         similar laws relating to creditors' rights generally or the rights of
         creditors of banks the deposit accounts of which are insured by the
         FDIC 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 articles of association 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.

                  SECTION 2.10. Federal Income Tax Allocations. Net income of
the Trust with respect to any Loan Group for any Collection Period as determined
for Federal income tax purposes (and each item of income, gain, loss and
deduction entering into the computation thereof) shall be allocated:

                  (a) among the holders of the Trust Certificates as of the
         close of business on the last day of such Collection Period, in
         proportion to their ownership of principal amount of Trust Certificates
         on such date, an amount of net income up to the sum of (i) the portion
         of the Certificateholders' Interest Distribution Amount and the
         Certificateholders' Interest Index Carryover if any, for the related
         Distribution Date allocable to such Collection 


                                      -4-
<PAGE>   10

         Period, (ii) interest on the excess, if any, of the Certificateholders'
         Interest Distribution Amount for the preceding Distribution Date over
         the amount in respect of interest that is actually distributed to such
         holders of the Trust Certificates on such preceding Distribution Date,
         to the extent permitted by law, at the Certificate Rate for such
         Collection Period and (iii) the portion of the market discount on the
         Financed Student Loans accrued during such quarter that is allocable to
         the excess, if any, of the initial aggregate principal amount of the
         Trust Certificates over their initial aggregate issue price; and

                  (b) to the Depositor, to the extent of any remaining net
         income.

If the net income of the Trust for any month is insufficient for the allocations
described in clause (a) above, subsequent net income shall first be allocated to
make up such shortfall before being allocated as provided in the preceding
sentence. Net losses of the Trust if any, for any month as determined for
Federal income tax purposes (and each item of income, gain, loss and deduction
entering into the computation thereof) shall be allocated to the Depositor to
the extent the Depositor is reasonably expected to bear the economic burden of
such net losses, and any remaining net losses shall be allocated among the
remaining holders of the Trust Certificates as of the close of business on the
last day of such month in proportion to their ownership of principal amount of
Trust Certificates on such Record Date. The Depositor is authorized to modify
the allocations in this paragraph if necessary or appropriate, in its sole
discretion, for the allocations to fairly reflect the economic income, gain or
loss to the Depositor or to the holders of the Trust Certificates, or as
otherwise required by the Code.


                                   ARTICLE III

                  Trust Certificates and Transfer of Interests
                  --------------------------------------------

                  SECTION 3.01. Initial Beneficial Ownership. Upon the formation
of the Trust by the contribution by the Depositor pursuant to Section 2.05 and
until the issuance of the Trust Certificates, the Depositor shall be the sole
beneficial owner of the Trust.

                  SECTION 3.02. The Trust Certificates. The Trust Certificates
shall be issued in denominations of $1,000 or in integral multiples of $1,000 in
excess thereof; provided, however, that the Trust Certificates issued to the
Depositor pursuant to Section 3.10 may be issued in such denomination as to
include any residual amount. The Trust Certificates shall be in the form of
Exhibit A hereto and 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 shall have been 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.

<PAGE>   11

                  SECTION 3.03. Authentication of Trust Certificates.
Concurrently with the initial sale of the Financed Student Loans to the Trust
pursuant to the Sale and Servicing 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 First Chicago Trust Company of New York, 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 3.04, 3.05 or 3.13
hereunder.

                  SECTION 3.04. 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 3.08, 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 Eligible
Lender Trustee 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 3.08, the
Eligible Lender Trustee shall execute, authenticate and deliver (or shall cause
First Chicago Trust Company of New York 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 holder of the Trust
Certificates, 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 3.08.

                  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 holder of the Trust Certificates
or his attorney duly authorized in writing, with such signature guaranteed by an
"eligible guarantor institution" meeting the requirements of the Certificate
Registrar, which requirements include membership or participation in Security
Transfer Agent's Medallion Program ("STAMP") or such other "signature guarantee
program" as may be determined by the Certificate Registrar in addition to, or in
substitution for, STAMP, all in accordance with the Exchange Act. 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.

                                      -6-
<PAGE>   12

                  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.

                  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) an employee benefit plan (as
defined in Section 3(3) of ERISA) that is subject to the provisions of Title I
of ERISA, (b) an individual retirement account described in Section 408(a) of
the Code or (c) 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 a Trust Certificate or an interest therein, the holder of the Trust
Certificates thereof or Certificate Owner thereof shall be deemed to have
represented and warranted that it is not a Benefit Plan.

                  SECTION 3.05. 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 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 the same
class in authorized denominations of like aggregate amount. In connection with
the issuance of any new Trust Certificate under this Section, the Eligible
Lender Trustee and the Certificate Registrar may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection therewith. Any duplicate Trust Certificate issued pursuant to this
Section shall constitute conclusive evidence of ownership in the Trust, as if
originally issued, whether or not the lost, stolen or destroyed Trust
Certificate shall be found at any time.

                  SECTION 3.06. Persons Deemed Owners. Prior to due presentation
of a Trust Certificate for registration of transfer, the Eligible Lender Trustee
or the Certificate Registrar and any agent of any thereof may treat the Person
in whose name any Trust Certificate shall be registered in the Certificate
Register as the owner of such Trust Certificate for the purpose of receiving
distributions pursuant to Section 5.01 and for all other purposes whatsoever,
and neither the Eligible Lender Trustee, the Certificate Registrar nor any agent
of any thereof shall be bound by any notice to the contrary.

                  SECTION 3.07. 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 


                                      -7-
<PAGE>   13

list, in such form as the Depositor may reasonably require, of the names and
addresses of the holders of the Trust Certificates as of the most recent Record
Date. If three or more holders of the Trust Certificates or one or more holders
of the Trust Certificates 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 holders of the Trust
Certificates 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 the holders of the Trust Certificates. Upon receipt of any such application,
the Eligible Lender Trustee will promptly notify the Depositor by providing a
copy of such application and a copy of the list of the holders of the Trust
Certificates produced in response thereto. Each holder of the Trust
Certificates, by receiving and holding a Trust Certificate, shall be deemed to
have agreed not to hold any of the Depositor, the Certificate Registrar or the
Eligible Lender Trustee accountable by reason of the disclosure of its name and
address, regardless of the source from which such information was derived.

                  SECTION 3.08. Maintenance of Office or Agency. The Eligible
Lender Trustee shall maintain in the Borough of Manhattan, The City of New York,
an office or offices or agency or agencies where Trust Certificates may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Eligible Lender Trustee in respect of the Trust
Certificates and the other Basic Documents may be served. The Eligible Lender
Trustee initially designates One First National Plaza, Suite 0126, Chicago,
Illinois 60670, as its principal Corporate Trust Office. The Eligible Lender
Trustee's New York office and its authenticating agent's office are located at
First Chicago Trust Company of New York, 14 Wall Street, 8th Floor, New York,
New York 10005, Attention: Corporate Trust Administration. The Eligible Lender
Trustee shall give prompt written notice to the Depositor and to the holders of
the Trust Certificates of any change in the location of the Certificate Register
or any such office or agency.

                  SECTION 3.09. Appointment of Certificate Paying Agent. The
Certificate Paying Agent shall make distributions to the holders of the Trust
Certificates from the amounts received from the Indenture Trustee out of the
Trust Accounts pursuant to Section 5.01 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 acceptable to the Administrator (which consent shall not be
unreasonably withheld). The Eligible Lender Trustee shall be permitted to resign
as Certificate Paying Agent upon 30 days' written notice to the Administrator.
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 cause such successor Certificate Paying Agent or any
additional Certificate Paying Agent 


                                      -8-
<PAGE>   14

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 holders of the Trust Certificates in trust for the benefit of the
holders of the Trust Certificates entitled thereto until such sums shall be paid
to such holders of the Trust Certificates. 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 7.01, 7.03, 7.04, 7.05 and 8.01 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 co-paying agent
unless the context requires otherwise.

                  SECTION 3.10. Disposition by Depositor. On and after the
Closing Date, the Depositor shall retain beneficial and record ownership of
Trust Certificates representing at least 1% of the Certificate Balance. Any
attempted transfer of any Trust Certificate that would reduce such interest of
the Depositor below 1% of the Certificate Balance shall be void. The Eligible
Lender Trustee shall cause any Trust Certificate issued to the Depositor on the
Closing Date (and any Trust Certificate issued in exchange therefor) to contain
a legend stating "THIS CERTIFICATE IS NONTRANSFERABLE".

                  SECTION 3.11. 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; provided, however, that one Definitive Certificate (as
defined below) may be issued to the Depositor pursuant to Section 3.10. 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 (other than the Depositor)
will receive a Definitive Certificate representing such Certificate Owner's
interest in such Trust Certificate, except as provided in Section 3.13. Unless
and until definitive, fully registered Trust Certificates (the "Definitive
Certificates") have been issued to Certificate Owners pursuant to Section 3.13:

                 (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 holder of the Trust Certificates 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;


                                      -9-
<PAGE>   15

                (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 3.13, the initial Clearing
         Agency will make book-entry transfers among the Clearing Agency
         Participants and receive and transmit payments of principal of and
         interest on the Trust Certificates to such Clearing Agency
         Participants; and

                 (v) whenever this Agreement requires or permits actions to be
         taken based upon instructions or directions of the holders of the 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 Certificates and has delivered such
         instructions to the Eligible Lender Trustee.

                  SECTION 3.12. Notices to Clearing Agency. Whenever a notice or
other communication to the holders of the Trust Certificates is required under
this Agreement, unless and until Definitive Certificates shall have been issued
to Certificate Owners pursuant to Section 3.13, the Eligible Lender Trustee
shall give all such notices and communications specified herein to be given to
the holders of the Trust Certificates to the Clearing Agency, and shall have no
obligations to the Certificate Owners.

                  SECTION 3.13. 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 the holders of the Trust Certificates. The
Definitive Certificates shall, at the expense of the Depositor, be printed,



                                      -10-
<PAGE>   16

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.

                       Actions by Eligible Lender Trustee

                  SECTION 4.01. Prior Notice to Certificateholders with Respect
to Certain Matters. With respect to the following matters, the Eligible Lender
Trustee shall not take action unless at least 30 days before the taking of such
action, the Eligible Lender Trustee shall have notified the holders of the Trust
Certificates in writing of the proposed action and the holders of the Trust

         collection of Financed Student Loans);

                  (b) the amendment of the Indenture by a supplemental indenture

         in circumstances where the consent of any holder of the Notes is not
         required and such amendment materially adversely affects the interest
         of the holders of the Trust Certificates;

                  (d) the amendment, change or modification of the
         Administration Agreement, except to cure any ambiguity or to amend or
         supplement any provision in a manner or add any provision that would
         not materially adversely affect the interests of the holders of the
         Trust Certificates; or

                  (e) the appointment pursuant to the Indenture of a successor
         Note Registrar, Certificate Paying Agent or Indenture Trustee or
         pursuant to this Agreement of a successor Certificate Registrar, or the
         consent to the assignment by the Note Registrar, Certificate Paying
         Agent or Indenture Trustee or Certificate Registrar of its obligations

                                      -11-
<PAGE>   17

Eligible Lender Trustee shall take the actions referred to in the preceding
sentence only upon written instructions signed by the holders of the Trust
Certificates.

                  SECTION 4.03. Action by Certificateholders with Respect to
Bankruptcy. The Eligible Lender Trustee shall not have the power to commence a
voluntary proceeding in bankruptcy relating to the Trust without the unanimous
prior approval of all holders of the Trust Certificates and the delivery to the
Eligible Lender Trustee by each such holder of the Trust Certificates of a
certificate certifying that such holder of the Trust Certificates reasonably
believes that the Trust is insolvent.

                  SECTION 4.04. Restrictions on Certificateholders' Power. The
holders of the Trust Certificates shall not direct the Eligible Lender Trustee
to take or refrain from taking any action if such action or inaction would be
contrary to any obligations of the Trust or the Eligible Lender Trustee under
the Higher Education Act or this Agreement or any of the other Basic Documents
or would be contrary to Section 2.03 nor shall the Eligible Lender Trustee be
permitted to follow any such direction, if given.

                  SECTION 4.05. Majority Control. Except as expressly provided
herein, any action that may be taken by the holders of the Trust Certificates

                                    ARTICLE V

                   Application of Trust Funds; Certain Duties
                   ------------------------------------------

                  SECTION 5.01. Application of Trust Funds. (a) On each
Distribution Date, the Eligible Lender Trustee will distribute to holders of the
Certificates, on a pro rata basis, amounts received from the Indenture Trustee
pursuant to Sections 5.05 and 5.06 of the Sale and Servicing Agreement on such
Distribution Date.

                  (b) On each Distribution Date, the Eligible Lender Trustee
         shall send to each holder of the Trust Certificates the statement
         provided to the Eligible Lender Trustee by the Administrator pursuant
         to Section 5.07 of the Sale and Servicing 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 holder of the Trust
         Certificates, such tax shall reduce the amount otherwise distributable
         to such holder in accordance with this Section. The Eligible Lender
         Trustee is hereby authorized and directed to retain from amounts
         otherwise distributable to the holders of the Trust Certificates
         sufficient funds for the payment of any tax that is legally owed by the
         Trust (but such authorization shall not 


                                      -12-
<PAGE>   18

         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 holder of the Trust
         Certificates shall be treated as cash distributed to such holder of the
         Trust Certificates at the time it is withheld by the Trust to be
         remitted to the appropriate taxing authority. If there is a possibility
         that withholding tax is payable with respect to a distribution (such as
         a distribution to a non-U.S. holder of the Trust Certificates), the
         Eligible Lender Trustee in its sole discretion may (but unless
         otherwise required by law shall be obligated to) withhold such amounts
         in accordance with this paragraph (c). In the event that a holder of
         the Trust Certificates wishes to apply for a refund of any such
         withholding tax, the Eligible Lender Trustee shall reasonably cooperate
         with such holder in making such claim so long as such holder of the
         Trust Certificates agrees to reimburse the Eligible Lender Trustee for
         any out-of-pocket expenses incurred.

                  SECTION 5.02. Method of Payment. Subject to Section 9.01(c),
distributions required to be made to the holders of the Trust Certificates on
any Distribution Date shall be made to each such holder of record on the
preceding Record Date either by wire transfer, in immediately available funds,
to the account of such holder at a bank or other entity having appropriate
facilities therefor, if such holder shall have provided to the Certificate
Registrar appropriate written instructions signed by two authorized officers, if
any, at least five Business Days prior to such Distribution Date and such
holder's Trust Certificates in the aggregate evidence a denomination of not less
than $1,000,000, or, if not, by check mailed to such holder at the address of
such holder appearing in the Certificate Register; provided, however, that,
unless Definitive Certificates have been issued pursuant to Section 3.13, with
respect to Trust Certificates registered on the Record Date in the name of the
nominee of the Clearing Agency (initially, such nominee to be Cede & Co.),
distributions will be made by wire transfer in immediately available funds to
the account designated by such nominee. Notwithstanding the foregoing, the final
distribution in respect of any Trust Certificate (whether on its Final Maturity
Date or otherwise) will be payable only upon presentation and surrender of such
Trust Certificate at the Corporate Trust Office of the Eligible Lender Trustee
or such other location specified in writing to the holder thereof.

                  SECTION 5.03. No Segregation of Moneys; No Interest. Subject
to Section 5.01, moneys received by the Eligible Lender Trustee hereunder need
not be segregated in any manner, except to the extent required by law or the
Sale and Servicing Agreement and may be deposited under such general conditions
as may be prescribed by law, and the Eligible Lender Trustee shall not be liable
for any interest thereon.

                  SECTION 5.04. Accounting and Reports to the Noteholders,
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
a calendar year basis on the accrual method of accounting, (b) deliver to each
holder of the Trust Certificates (and to each Person who was a holder of the
Trust Certificates at any time during the applicable calendar year), as may be
required by the Code and applicable Treasury Regulations, such information as
may be required 


                                      -13-
<PAGE>   19

(including Schedule K-1) to enable each such holder of the Trust Certificates to
prepare its Federal and state income tax returns, (c) file such tax returns
relating to the Trust (including a partnership information return, Internal
Revenue Service Form 1065), and make such elections as may from time to time be
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 5.01(c) with
respect to income or distributions to the holders of the Trust Certificates. 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 Financed
Student Loans. The Eligible Lender Trustee shall not make the election provided
under Section 754 of the Code.

                  SECTION 5.05. 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 holder of the Trust Certificates 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.


                                   ARTICLE VI

                 Authority and Duties of Eligible Lender Trustee
                 -----------------------------------------------

                  SECTION 6.01. General Authority. The Eligible Lender Trustee
is authorized and directed to execute and deliver the Basic Documents to which
the Trust is to be a party and each certificate or other document attached as an
exhibit to or contemplated by the Basic Documents to which the Trust is to be a
party, in each case, in such form as the Depositor shall approve as evidenced
conclusively by the Eligible Lender Trustee's execution thereof, and, on behalf
of the Trust, to direct the Indenture Trustee to authenticate and deliver Notes
in the aggregate principal amount of $830,400,000. The Eligible Lender Trustee

                  SECTION 6.02. 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 holders of the Trust Certificates, 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 any 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 Financed Student Loans
or to maintain, monitor or otherwise supervise the administration, servicing or
collection of the Financed Student Loans.

                  SECTION 6.03. Action Upon Instruction. (a) Subject to Article
IV, Section 7.01 and in accordance with the terms of the Basic Documents, the
holders of the Trust Certificates may by written instruction direct the Eligible
Lender Trustee in the management of the Trust. Such direction may be exercised
at any time by written instruction of the holders of the Trust Certificates
pursuant to Article IV.

                  (b) The Eligible Lender Trustee shall not be required to take
         any action hereunder or under any other Basic Document if the Eligible
         Lender Trustee shall have reasonably determined, or shall have been
         advised by counsel, that such action is likely to result in liability
         on the part of the Eligible Lender Trustee or is contrary to the terms
         hereof 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
         of action 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 holders of the Trust Certificates requesting
         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 holders of the Trust Certificates 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 holders of the Trust
         Certificates, 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 holders of the Trust
         Certificates requesting instruction and, to the extent that the
         Eligible Lender Trustee acts or refrains from acting in good faith in
         accordance with any such instruction received, the Eligible Lender
         Trustee shall not be liable, on account of such action or inaction, to
         any Person. If the Eligible Lender Trustee shall not have received
         appropriate instruction within 10 days of such notice (or within such
         shorter period of time as reasonably may be specified in such notice or
         may be necessary under the circumstances) it may, but shall be under no
         duty to, take or refrain from taking such action, not inconsistent with
         this Agreement or the other Basic Documents, as it shall deem to be in
         the best interests of the holders of the Trust Certificates, and shall
         have no liability to any Person for such action or inaction.

                  SECTION 6.04. No Duties Except as Specified in this Agreement,
the Sale and Servicing Agreement, the Supplemental Sale and Servicing 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, the Sale and
Servicing Agreement, the Supplemental Sale and Servicing Agreement or in any
document or written instruction received by the Eligible Lender Trustee pursuant
to Section 6.03; 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, The First National Bank
of Chicago 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 6.05. No Action Except Under Specified Documents or
Instructions. The Eligible Lender Trustee shall not manage, control, use, sell,
service, dispose of or 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 6.03.

                  SECTION 6.06. Restrictions. The Eligible Lender Trustee shall
not take any action (a) that is inconsistent with the purposes of the Trust set
forth in Section 2.03 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 holders of the Trust Certificates shall not
direct the Eligible Lender Trustee to take action that would violate the
provisions of this Section.


                                   ARTICLE VII

         liability in the 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 funds or

         assured or provided to it;

                  (d) under no circumstances shall the Eligible Lender Trustee

         Eligible Lender Trustee security or indemnity satisfactory to it
         against the costs, expenses and liabilities that may be incurred by the
         Eligible Lender Trustee therein or thereby. The right of the Eligible
         Lender Trustee to perform any discretionary act enumerated in this
         Agreement or in any other Basic Document shall not be construed as a

         Agreement, nor the consummation by it of the transactions contemplated

         regulation governing the banking or trust powers of the Eligible Lender
         Trustee or any judgment or order binding on it, or constitute any

responsibility for the correctness thereof. The Eligible Lender Trustee makes no
representations as to the validity or sufficiency of this Agreement, the Trust
Certificates or any other Basic Document (other than the signature and
countersignature of the Eligible Lender Trustee on the Trust Certificates) or
the Notes, or of any Financed Student Loan or related documents. Subject to
Section 7.07 hereof, the Eligible Lender Trustee shall at no time have any
responsibility (or liability except for willfully or negligently terminating or
allowing to be terminated any of the Guarantee Agreements, in a case where the
Eligible Lender Trustee knows of any facts or circumstances which will or could
reasonably be expected to result in any such termination) for or with respect to

                         ------------------------------

                  SECTION 9.01. Termination of Trust Agreement. (a) This
Agreement (other than Article VIII) and the Trust shall terminate and be of no

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

         Distribution Date is not applicable, payments being made only upon

         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

Lender Trustee shall give a second written notice to the remaining holders of
the Trust Certificates to surrender their Trust Certificates for cancellation

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 holders of the Trust Certificates 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.

                  SECTION 9.02. Dissolution upon Insolvency of the Depositor. In

the Eligible Lender Trustee shall have received written instructions from the
holders of the Trust Certificates (other than the Depositor) representing more
than 50% of the Certificate Balance (not including the principal amount of Trust
Certificates held by the Depositor), to the effect that each such party
disapproves of the liquidation of the Financed Student Loans and termination of
the Trust, in which event the Trust shall continue in accordance with the Basic
Documents. Promptly after the occurrence of any Insolvency Event with respect to
the Depositor, (i) the Depositor shall give the Indenture Trustee and the
Eligible Lender Trustee written notice of such Insolvency Event, (ii) the
Eligible Lender Trustee shall, upon the receipt of such written notice from the
Depositor, give prompt written notice to the holders of the Trust Certificates
and the Indenture Trustee, of the occurrence of such event and (iii) the
Indenture Trustee shall, upon receipt of written notice of such Insolvency Event
from the Eligible Lender Trustee or the Depositor, give prompt written notice to
the holders of the Notes of the occurrence of such event; 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 9.02. Upon a termination 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.

                     Successor Eligible Lender Trustees and
                     --------------------------------------
                       Additional Eligible Lender Trustees
                       -----------------------------------

                  SECTION 10.01. 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 Financed Student Loans on behalf of the Trust, with a valid lender
identification number with respect to the Trust from the Department; (ii) being
authorized to exercise corporate trust powers and hold legal title to the
Financed 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) incorporated or authorized to do business in the State of New
York or which is a national bank having an office located within the State of
New York; and (vi) having (or having a parent which has) a rating of at least
Baa3 by Moody's. 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 10.02.

                  SECTION 10.02. 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 10.01 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
eligible in accordance with the provisions of Section 10.01 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 


                                      -23-
<PAGE>   29

Trustee by written instrument, in duplicate, one copy of which instrument shall
be delivered to the outgoing Eligible Lender Trustee so removed and one copy to
the successor Eligible Lender Trustee and payment of all fees owed to the
outgoing Eligible Lender Trustee.

                  Any resignation or removal of the Eligible Lender Trustee and
appointment of a successor Eligible Lender Trustee pursuant to any of the
provisions of this Section shall not become effective until acceptance of
appointment by the successor Eligible Lender Trustee pursuant to Section 10.03
and payment of all fees and expenses owed to the outgoing Eligible Lender
Trustee. The Administrator shall provide notice of such resignation or removal
of the Eligible Lender Trustee to each of the Rating Agencies.

                  SECTION 10.03. Successor Eligible Lender Trustee. Any
successor Eligible Lender Trustee appointed pursuant to Section 10.02 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 appointment
as provided in this Section unless at the time of such acceptance such successor
Eligible Lender Trustee shall be eligible pursuant to Section 10.01.

                  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 holders of the Trust
Certificates, the Indenture Trustee, all holders of the Notes 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 10.04. 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 


                                      -24-
<PAGE>   30

hereunder; provided that such corporation shall be eligible pursuant to Section
10.01; provided further that the Eligible Lender Trustee shall mail notice of
such merger or consolidation to the Rating Agencies.

                  SECTION 10.05. 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 10.01, 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) and (v) of Section 10.01 and no notice of the appointment of any
co-trustee or separate trustee shall be required pursuant to Section 10.03.

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

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

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

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

                  Any notice, request or other writing given to the Eligible
Lender Trustee shall be deemed to have been given to each of the then separate
trustees and co-trustees, as effectively as 


                                      -25-
<PAGE>   31

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.



                                   ARTICLE XI

                                  Miscellaneous
                                  -------------

                  SECTION 11.01. 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 holders of the
Notes or the holders of the Trust Certificates, 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
holders of the Notes or the holders of the Trust Certificates; provided,
however, that such action shall not, as evidenced by an Opinion of Counsel,
adversely affect in any material respect the interests of any holder of the
Notes or holder of the Trust Certificates.

                  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, (i) with the consent of the holders of Notes evidencing not
less than a majority of the Outstanding Amount of the Notes and (ii) with the
consent of the holders of the Trust 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 holders of the Notes or the
holders of the Trust Certificates; 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 Financed Student Loans or
distributions that shall be required to be made for the benefit of the holders
of any class of Notes or the holders of any class of Trust Certificates or (b)
reduce the aforesaid percentage of the Outstanding Amount of the Notes and the
Certificate Balances required to consent to any such amendment, 


                                      -26-
<PAGE>   32

without the consent of all the outstanding holders of the Notes and holders of
the Trust Certificates.

                  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 holder of the Trust Certificates, the
Indenture Trustee and each of the Rating Agencies.

                  It shall not be necessary for the consent of the holders of
the Trust Certificates, the holders of the Notes 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 the holders of the Trust Certificates provided for in this Agreement
or in any other Basic Document) and of evidencing the authorization of the
execution thereof by holders of the Trust Certificates shall be subject to such
reasonable requirements as the Eligible Lender Trustee may prescribe.

                  Prior to the execution of any amendment to this Agreement, the
Eligible Lender Trustee shall be entitled to receive and rely upon an Opinion of
Counsel stating that the execution of such amendment is authorized or permitted
by this Agreement. The Eligible Lender Trustee may, but shall not be obligated
to, enter into any such amendment which affects the Eligible Lender Trustee's
own rights, duties or immunities under this Agreement or otherwise.

                  SECTION 11.02. No Legal Title to Trust Estate in
Certificateholders. The holders of the Trust Certificates shall not have legal
title to any part of the Trust Estate. The holders of the Trust Certificates
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 holders of the Trust Certificates 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 11.03. Limitations on Rights of Others. Except for
Section 2.07, the provisions of this Agreement are solely for the benefit of the
Eligible Lender Trustee, the Depositor, the holders of the Trust Certificates,
the Administrator and, to the extent expressly provided herein, the Indenture
Trustee and the holders of the Notes, and nothing in this Agreement (other than
Section 2.07), whether express or 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 11.04. Notices. (a) Unless otherwise expressly
specified or permitted by the terms hereof, all notices shall be in writing and
shall be deemed given upon receipt by the intended recipient or three Business
Days after mailing if mailed by certified mail, postage prepaid (except that
notice to the Eligible Lender Trustee shall be deemed given only upon actual

addressed to its Corporate Trust Office; if to the Depositor, addressed to Key

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 11.06. Separate Counterparts. This Agreement may be
executed by the parties hereto in separate counterparts, each of which when so
executed and delivered shall be an original, but all such counterparts shall
together constitute but one and the same instrument.

                  SECTION 11.07. Successors and Assigns. All covenants and
agreements contained herein shall be binding upon, and inure to the benefit of,
the Depositor and its successors, the Eligible Lender Trustee and its
successors, each holder of the Trust Certificates and its successors and
permitted assigns, all as herein provided. Any request, notice, direction,
consent, waiver or other instrument or action by a holder of the Trust
Certificates shall bind the successors and assigns of such holder.

time institute against the Trust any bankruptcy proceedings under any United
States Federal or state bankruptcy or similar law in connection with any

         Agreement, each holder of the Trust Certificates, by accepting a Trust
         Certificate, and the Indenture Trustee and each holder of the Notes by
         accepting the benefits of this Agreement, hereby covenant and agree
         that they 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,
         this Agreement or any of the other Basic Documents.

                  SECTION 11.09. No Recourse. Each holder of the Trust
Certificates by accepting a Trust Certificate acknowledges that such holder's
Trust Certificates represent beneficial interests in the Trust only and do not
represent interests in or obligations of the Seller,

any Servicer, the Administrator, the Eligible Lender Trustee, the Indenture
Trustee or any Affiliate thereof or any officer, director or employee of any

as may be expressly set forth or contemplated in this Agreement, the Trust
Certificates or the other Basic Documents.

                  SECTION 11.10. Headings. The headings of the various Articles
and Sections herein are for convenience of reference only and shall not define
or limit any of the terms or provisions hereof.

                  SECTION 11.11. Governing Law. This Agreement shall be

                  THIS CERTIFIES THAT _______________ is the registered owner of
dollars nonassessable, fully-paid, fractional undivided interest in the KeyCorp
Student Loan Trust 1999-A (the "Trust"), a trust formed under the laws of the
State of New York by Key Bank USA, National Association, a national banking
association (the "Seller"). The Trust was created pursuant to a Trust Agreement
dated as of July 13, 1998, as amended and restated as of January 1, 1999 (the
"Trust Agreement"), between the Seller and The First National Bank of Chicago, a
national banking association, not in its individual capacity but solely as
eligible lender trustee on behalf of the Trust (the "Eligible Lender Trustee"),
a summary of certain of the pertinent provisions of which is set forth below. To
the extent not otherwise defined herein, the capitalized terms used herein have
the meanings assigned to them in Appendix A to the Sale and Servicing Agreement
(the "Sale and Servicing Agreement") dated as of January 1, 1999, among the
Trust, the Eligible Lender Trustee, the Seller, Pennsylvania Higher Education
Assistance Agency, as servicer ( "Servicer"), EFS Services, Inc., as servicer
("Servicer"), and Key Bank USA, National Association, as administrator (the
"Administrator"); such Appendix A also contains rules as to usage that shall be
applicable herein.

                  This Certificate is one of the duly authorized Certificates
designated as "Floating Rate Asset Backed Certificates" (herein called the
"Trust Certificates"). Issued under the Indenture dated as of January 1, 1999,
between the Trust and Bankers Trust Company, as Indenture Trustee, are Notes
designated as "Floating Rate Asset Backed Notes" (the "Notes"). 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 law school,
medical school, dental school, graduate business school and other graduate
school student loans (the "Financed Student Loans"), all moneys paid thereunder
(except from the proceeds on any Guarantee Payments made by TERI) on or after
January 1, 1999 (or, in the case of Financed Student Loans that constitute
Additional Student Loans, on or after the respective Subsequent Cutoff Dates),
certain bank accounts and the proceeds thereof and certain other rights under
the Trust Agreement and the Sale and 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, as set
forth in the Sale and Servicing Agreement.

                  Under the Trust Agreement, to the extent of funds available
therefor, interest on the Certificate Balance of this Trust Certificate at the
Certificate Rate for this Trust Certificate, and principal and certain other
amounts will be distributed on the twenty-seventh day of each March, June,
September and December (or, if such twenty-seventh day is not a Business Day,
the next succeeding Business Day) (each a "Distribution Date"), commencing on
June 28, 1999 to the person in whose name this Trust Certificate is registered
at the close of business on the twenty-sixth day of the calendar month in which
such Distribution Date occurs (the "Record Date"), in each case to the extent of
such holder's fractional undivided interest in the amount or amounts to be
distributed to the holders of the Trust Certificates on such Distribution Date
pursuant to the Sale and Servicing Agreement.


<PAGE>   38

                  The Trust Certificates may be paid in part, in certain
circumstances on a pro rata basis among all holders of Securities, on June 28,
1999 to the extent the Subsequent Pool Pre-Funded Amount is greater than
$10,000,000 as of the Special Determination Date after giving effect to the
purchase of any Subsequent Pool Student Loans on such date.

                  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 holders of the Notes as described in the Sale
and Servicing Agreement and the Indenture.

                  It is the intent of the Seller, each Servicer, the
Administrator, the holders of the Trust Certificates and the Certificate Owners
that, for purposes of Federal income, state and local income and franchise and
any other income taxes, the Trust will be treated as a partnership and the
holders of the Trust Certificates (including the Depositor in its capacity as
recipient of distributions from the Reserve Account) will be treated as partners
in that partnership. The Depositor and the other holders of the Trust
Certificates 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.

                  Each holder of a Trust Certificate 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
holder or Certificate Owner, as the case may be, will not at any time institute
against the Seller or the Trust, or join in any institution against the Seller
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.

                  The Trust Certificates do not represent an obligation of, or
an interest in, the Seller, any Servicer, 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 Financed Student Loans, all as more specifically set forth in the
Sale and Servicing Agreement. A copy of each of the Sale and Servicing Agreement
and the Trust Agreement may be examined during normal business hours at the
principal office of the Seller, and at such other places, if any, designated by
the Seller, by any holder of the Trust Certificates upon request.

                  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) an individual retirement account described in Section
408(a) of the Internal Revenue Code of 1986, as amended, 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.

                  This Trust Certificate 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
shall be determined in accordance with such laws.

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

                  IN WITNESS WHEREOF, the Eligible Lender Trustee on behalf of
the Trust and not in its individual capacity has caused this Trust Certificate
to be duly executed as of the date set forth below.

correspondence, notices of death, disability or bankruptcy and requests for
deferrals or forbearances), on and after the related Subsequent Cutoff Date,
made from time to time during the Funding Period.

                  (b) The Seller shall transfer to the Eligible Lender Trustee

                  (iii) the Seller shall, to the extent required by Section

         Federal or State tax consequence to the Issuer, the holders of Notes or
         the holders of Certificates;

<PAGE>   8



                  (ix) the Seller shall have taken any action required to
         maintain the first perfected ownership interest of the Issuer in the
         Trust Estate and the first perfected security interest of the Indenture
         Trustee in the Collateral;

                  (x) no selection procedures believed by the Seller to be
         adverse to the interests of the holders of Certificates or the holders
         of Notes shall have been utilized in selecting the Subsequent Pool
         Student Loans or the Other Subsequent Student Loans;

                  (xi) no Consolidation Loan will be transferred to the Issuer
         unless at least one underlying student loan to be consolidated is a
         Financed Student Loan already held by the Eligible Lender Trustee on
         behalf of the Issuer; and

                  (xii) the Issuer may not purchase any Other Subsequent Student
         Loans which are (a) Stafford Loans, if after giving effect to such
         purchase Stafford Loans which are Other Subsequent Student Loans in an
         aggregate principal amount of $30,000,000 have been purchased by the
         Issuer, (b) Federal Consolidation Loans, if after giving effect to such
         purchase Federal Consolidation Loans which are Other Subsequent Student
         Loans in an aggregate principal amount of $30,000,000 have been
         purchased by the Issuer, (c) Private Consolidation Loans, if after
         giving effect to such purchase Private Consolidation Loans which are
         Other Subsequent Student Loans in an aggregate principal amount of
         $30,000,000 have been purchased by the Issuer and (d) Private Loans,
         which are not Private Consolidation Loans, if after giving effect to
         such purchase Private Loans, which are not Private Consolidation Loans
         and are Other Subsequent Student Loans, in an aggregate principal
         amount of $30,000,000 have been purchased by the Issuer, in each case
         without giving effect to any capitalized interest accrued thereon;

provided, however, that the Seller shall not incur any liability as a result of
transferring Subsequent Pool Student Loans or Other Subsequent Student Loans on
any Transfer Date at a time when the condition set forth in clause (v) was not
satisfied, if at the time of such transfer the Authorized Officers of the
Seller, after reasonable inquiry of in-house counsel to the Seller, were not
aware of any fact that would reasonably suggest that such condition would not be
satisfied as of such date.

                  (c) The Seller covenants to transfer during the Funding Period
to the Eligible Lender Trustee on behalf of the Issuer pursuant to paragraph (a)

less than $30,000,000 (less the Pre-Funded Amount thereof, if any, used by the
Trust to fund shortfalls in the payment of interest on the Notes and the
Certificates); provided, however, that the Seller shall have no liability for a
breach of the foregoing covenant as a result of the Seller not having made or
owned prior to the date hereof Other Subsequent Student Loans equal to the
amount specified above during the Funding Period, the Seller not being able to
transfer Other Subsequent Student Loans because of Section 2.02(b)(xii) or there
being insufficient funds available in the Escrow Account and the Pre-Funding
Account for the Eligible Lender Trustee to consummate such acquisitions.

                  SECTION 2.03. Conveyance of Financed Federal Loans and
Financed Private Loans by the Eligible Lender Trustee to the Seller in
Connection with Consolidation Loans. On any date, upon receipt of written notice
(or telephonic or facsimile notice followed by written notice) from the Seller
(or from the Servicer on behalf of the Seller) by the Eligible Lender Trustee
and the Indenture Trustee, the Eligible Lender Trustee will convey to the Seller
the Financed Federal Loans and Financed Private Loans identified in such notice,
which are to be repaid pursuant to the Consolidation Loans to be made by the
Seller.

                  SECTION 2.04. Endorsement. The Seller hereby appoints each of
the Eligible Lender Trustee and the Indenture Trustee as the Seller's true and
lawful attorney-in-fact with full power of substitution to endorse the Seller's
name on any promissory note evidencing the Initial Financed Student Loans and
any Additional Student Loans transferred to the Eligible Lender Trustee on
behalf of the Trust pursuant to Sections 2.01 and 2.02. The Seller acknowledges
and agrees that this power of attorney shall be construed as a power coupled
with an interest, shall be irrevocable as long as the Trust Agreement remains in
effect and shall continue in effect until the Trust Agreement terminates.


                                  ARTICLE III

                           The Financed Student Loans

                  SECTION 3.01. Representations and Warranties of Seller with
Respect to the Financed Student Loans. The Seller makes the following
representations and warranties as to the Financed Student Loans on which the
Issuer is deemed to have relied in acquiring (through the Eligible Lender
Trustee) the Financed Student Loans. Such representations and warranties speak
as of the execution and delivery of this Agreement and as of the Closing Date,
in the case of the Initial Financed Student Loans and the Subsequent Pool
Student Loans, and as of the applicable Transfer Date, in the case of the Other
Subsequent Student Loans, but shall survive the sale, transfer and assignment of
the Financed Student Loans to the Eligible Lender Trustee on behalf of the
Issuer and the pledge thereof to the Indenture Trustee pursuant to the
Indenture.

                  (i) Characteristics of Financed Student Loans. Each Financed
         Student Loan (A) was originated in the United States of America, its
         territories, its possessions or other areas subject to its jurisdiction
         by the Seller in the ordinary course of its business to an eligible
         borrower under applicable law and agreements and was fully and properly
         executed by the parties thereto and (B) provides or, when the payment
         schedule with respect thereto is determined, will provide for payments
         on a periodic basis that fully amortize the principal amount of such
         Financed Student Loan by its maturity and yield interest at the rate
         applicable thereto, as such maturity may be modified in accordance with
         any applicable deferral or forbearance periods granted in accordance
         with applicable laws and restrictions, including those of the Higher
         Education Act, any Guarantee Agreement or the Programs. Each Financed
         Student Loan that is a Financed Federal Loan qualifies the holder
         thereof to receive Interest Subsidy Payments (other than SLS Loans,
         unsubsidized Stafford Loans and certain Consolidation Loans) and
         Special 



                                      -5-
<PAGE>   10



         Allowance Payments from the Department and Guarantee Payments from the
         applicable Guarantor and qualifies the applicable Guarantor to receive
         reinsurance payments thereon from the Department. Each Financed Student
         Loan that is a Financed Private Loan qualifies the holder thereof to
         receive Guarantee Payments from the applicable Guarantor pursuant to
         the applicable Guarantee Agreement.

                  (ii) Schedules of Financed Student Loans. The information set
         forth in Schedules A and B to this Agreement and Schedule A to the
         related Transfer Agreement is true and correct in all material respects
         as of the opening of business on the Cutoff Date (with respect to
         Schedules A and B to this Agreement) or each applicable Subsequent
         Cutoff Date, as applicable, and no selection procedures believed to be
         adverse to the holders of Notes or the holders of Certificates were
         utilized in selecting the Initial Financed Student Loans or the
         applicable Additional Student Loans, as applicable. The computer tape
         regarding the Initial Financed Student Loans and the Subsequent Pool
         Student Loans made available to the Issuer and its assigns is true and
         correct in all respects as of the Cutoff Date.

                  (iii) Compliance with Law. Each Financed Student Loan complied
         at the time it was originated or made and at the execution of this
         Agreement or the applicable Transfer Agreement, as the case may be,
         complies, and the Seller and its agents, with respect to each such
         Financed Student Loan, have at all times complied, in all material
         respects with all requirements of applicable Federal, state and local
         laws and regulations thereunder, including the Higher Education Act,
         usury law, the Federal Truth-in-Lending Act, the Equal Credit
         Opportunity Act, the Federal Reserve Board's Regulation B and other
         consumer credit laws and equal credit opportunity and disclosure laws
         and all applicable requirements of the Guarantee Agreements.

                  (iv) Binding Obligation. Each Financed Student Loan represents
         the genuine, legal, valid and binding payment obligation in writing of
         the borrower thereof, enforceable by or on behalf of the holder thereof
         in accordance with its terms, and no Financed Student Loan has been
         satisfied, subordinated or rescinded, subject to clause (xiii) below.

                  (v) No Defenses. No right of rescission, setoff, counterclaim
         or defense has been asserted or threatened or exists with respect to
         any Financed Student Loan.

                  (vi) No Default. No Initial Financed Student Loan or
         Subsequent Pool Student Loan has a payment that is more than 180 days
         overdue as of the Cutoff Date or, with respect to the Other Subsequent
         Student Loans, more than 90 days overdue as of the applicable
         Subsequent Cutoff Date, as the case may be, and, except as permitted in
         this paragraph, no default, breach, violation or event permitting
         acceleration under the terms of any Financed Student Loan has occurred;
         and, except for payment defaults continuing for a period of not more
         than 150 days or 90 days, as applicable, no continuing condition that
         with notice or the lapse of time or both would constitute a default,
         breach, violation or event permitting acceleration under the terms of
         any Financed Student Loan has arisen; 




                                      -6-
<PAGE>   11


         and the Seller has not waived and shall not waive any of the foregoing
         other than as permitted by the Basic Documents.

                  (vii) Title. It is the intention of the Seller that the
         transfer and assignment herein contemplated constitute a sale of the
         Financed Student Loans from the Seller to the Eligible Lender Trustee
         on behalf of the Issuer and that the beneficial interest in and title
         to such Financed Student Loans not be part of the debtor's estate in
         the event of the appointment of a receiver with respect to the Seller.
         No Financed Student Loan has been sold, transferred, assigned or
         pledged by the Seller to any Person other than the Eligible Lender
         Trustee on behalf of the Issuer. Immediately prior to the transfer and
         assignment herein contemplated, the Seller had good title to each
         Financed Student Loan, free and clear of all Liens and, immediately
         upon the transfer thereof, the Eligible Lender Trustee on behalf of the
         Issuer shall have good title to each such Financed Student Loan, free
         and clear of all Liens or the transfer shall have been perfected under
         the UCC.

                  (viii) Lawful Assignment. No Financed Student Loan has been
         originated in, or is subject to the laws of, any jurisdiction under
         which the sale, transfer and assignment of such Financed Student Loan
         or any Financed Student Loan under this Agreement, each Transfer
         Agreement or the Indenture is unlawful, void or voidable.

                  (ix) Security Interest Perfected. All filings (including UCC
         filings) and/or delivery requirements necessary in any jurisdiction to
         give the Eligible Lender Trustee on behalf of the Issuer a first
         perfected ownership interest in the Financed Student Loans, and to give
         the Indenture Trustee a first perfected security interest therein, have
         been made or satisfied, as the case may be.

                  (x) One Original. There is only one original executed copy of
         the promissory note evidencing each Financed Student Loan.

                  (xi) Principal Balance. The aggregate principal balance of the
         Initial Financed Student Loans, plus accrued interest to be capitalized
         with respect thereto, as of January 1, 1999, is $767,111,823.09, and
         the aggregate principal balance of the Subsequent Pool Student Loans,
         plus accrued interest to be capitalized with respect thereto, as of
         January 1, 1999 is $32,180,803.50.

                  (xii) No Claims. As of the Cutoff Date, no claim for payment
         with respect to an Initial Financed Student Loan has been made to a
         Guarantor, and as of the related Subsequent Cutoff Date no claim for
         payment with respect to an Additional Student Loan will have been made.

                  (xiii) No Bankruptcies or Deaths. No borrower of any Financed
         Student Loan as of January 1, 1999 (in the case of the Initial Financed
         Student Loans), or the applicable Subsequent Cutoff Date (in the case
         of Additional Student Loans) was noted in the related Financed Student
         Loan File as being currently involved in a bankruptcy proceeding or as
         having died.

                  (xiv) U.S. Obligors. Less than 1% of the Financed Student
         Loans are due from Persons not having a mailing address in the United
         States of America.

                  (xv) Interest Accruing. Each Financed Student Loan is accruing
         interest (whether or not such interest is being paid currently, by the
         borrower or by the Department, or is being capitalized), except as
         otherwise expressly permitted by the Basic Documents.

                  (xvi) Seller's Representations. The representations and
         warranties of the Seller contained in Section 6.01 are true and
         correct.

                  SECTION 3.02. Repurchase upon Breach; Reimbursement. The
Seller, any Servicer or the Eligible Lender Trustee, as the case may be, shall
inform the other parties to this Agreement and the Indenture Trustee promptly,
in writing, upon the discovery of any breach of the Seller's representations and
warranties made pursuant to Section 3.01 or Section 6.01. Unless any such breach
shall have been cured within 60 days following the discovery thereof by the
Eligible Lender Trustee or receipt by the Eligible Lender Trustee of written
notice from the Seller or any Servicer of such breach, the Seller shall be
obligated to repurchase any Financed Student Loan in which the interests of the
holders of Notes or the holders of Certificates are materially and adversely
affected by any such breach as of the first day succeeding the end of such
60-day period that is the last day of a Collection Period; provided that it is
understood that any such breach that does not affect any Guarantor's obligation
to guarantee payment of such Financed Student Loan to the Eligible Lender
Trustee in accordance with the Guarantee Agreements will not be considered to
have a material adverse effect for this purpose. In consideration of and
simultaneously with the repurchase of the Financed Student Loan, the Seller
shall remit the Purchase Amount, in the manner specified in Section 5.04, and
the Issuer shall execute such assignments and other documents reasonably
requested by the Seller in order to effect such transfer. Upon any such transfer
of a Financed Student Loan, legal title to, and beneficial ownership and control
of, the related Financed Student Loan File will thereafter belong to the Seller.
In addition, if any such breach by the Seller does not trigger such a repurchase
obligation but does result in the refusal by a Federal Guarantor to guarantee
all or a portion of the accrued interest, or the loss (including any obligation
of the Issuer to repay to the Department) of certain Interest Subsidy Payments
and Special Allowance Payments, with respect to a Financed Federal Loan, then,
unless such breach, if curable, is cured within 60 days, the Seller shall
reimburse the Issuer by remitting an amount equal to the sum of all such
non-guaranteed interest amounts and such forfeited Interest Subsidy Payments and
Special Allowance Payments in the manner specified in Section 5.04. Subject to
the provisions of Section 6.03, the sole remedy of the Issuer, the Eligible
Lender Trustee, the Indenture Trustee, the holders of Notes or the holders of
Certificates with respect to a breach of representations and warranties pursuant
to Section 3.01 and the agreement contained in this Section shall be to require
the Seller to repurchase Financed Student Loans or to reimburse the Issuer as
provided above pursuant to this Section, subject to the conditions contained
herein.

                  SECTION 3.03. Custody of Financed Student Loan Files. To
assure uniform quality in servicing the Financed Student Loans and to reduce
administrative costs, the Issuer hereby revocably appoints (x) PHEAA, in its
capacity as a Servicer and PHEAA hereby accepts such appointment, to act for the
benefit of the Issuer and the Indenture Trustee as custodian of the following
documents or instruments related to the Financed Student Loans it services (as
set forth in Schedules A and B hereto) and (y) EFS and EFS hereby accepts such
appointment, to act for the benefit of the Issuer and the Indenture Trustee as
custodian of the following documents or instruments related to the Financed
Student Loans it services (as set forth in Schedules A and B hereto), in each
case, which are hereby constructively delivered to the Indenture Trustee, as
pledgee of the Issuer (or, in the case of the Additional Student Loans, will as
of the applicable Transfer Date be constructively delivered to the Indenture
Trustee, as pledgee of the Issuer) with respect to each Financed Student Loan:

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

                  (b) the original loan application fully executed by the
borrower; and

                  (c) any and all other documents and computerized records that
any of the applicable Servicer, the Administrator or the Seller shall keep on
file, in accordance with its customary procedures, relating to such Financed
Student Loan or any Obligor with respect thereto.

                  Unless otherwise specified, all references to actions to be
taken by "the Servicer" as "custodian" under this Article III or any other
provision of this Agreement with respect to the Financed Student Loans or the
Financed Student Loan Files shall be deemed to refer to actions to be taken by
each Servicer with respect to the Financed Student Loans serviced by such
Servicer, as specified on Schedules A and B hereto, or with respect to the
Financed Student Loan Files held by such Servicer. Consistent with the
foregoing, but only insofar as the context so permits, this Article III is to be
read with respect to each custodian as if such custodian alone was holding its
respective Financed Student Loans hereunder.

                  SECTION 3.04. Duties of Servicer as Custodian. (a)
Safekeeping. The Servicer, as custodian, shall hold the Financed 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
Financed 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 all comparable
student loans that the Servicer services and shall ensure that it complies fully
and completely with all applicable Federal and State laws, including the Higher
Education Act, with respect thereto. The Servicer shall conduct, or cause to be
conducted, periodic audits of the Financed Student Loan Files held by it under
this Agreement and of the related accounts, records and computer systems, in
such a manner as shall enable the Issuer or the Indenture Trustee to verify the
accuracy of the Servicer's record keeping. The Servicer shall promptly report to
the Issuer and the Indenture Trustee any failure on its part to hold the


                                      -9-
<PAGE>   14



Financed 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 Financed Student Loan Files.

                  (b) Maintenance of and Access to Records. The Servicer, as
custodian, shall maintain each Financed Student Loan File at one of its offices
specified in Schedule C to this Agreement or at such other office as shall be
specified by written notice to the Issuer and the Indenture Trustee not later
than 90 days after any change in location. 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 Financed 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.

                  (c) Release of Documents. Upon instruction from the Indenture
Trustee, the Servicer, as custodian, shall release any Financed 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 designate, as soon as practicable.

                  SECTION 3.05. Instructions; Authority To Act. The Servicer, as
custodian, shall be deemed to have received proper instructions with respect to
the Financed Student Loan Files upon its receipt of written instructions signed
by a Responsible Officer of the Indenture Trustee.

                  SECTION 3.06. Custodian's Indemnification. The Servicer as
custodian shall pay for any loss, liability or expense, including reasonable
attorney's fees, that may be imposed on, incurred by or asserted against the
Issuer, the Eligible Lender Trustee or the Indenture Trustee or any of their
officers, directors, employees and agents as the result of any improper act or
omission in any way relating to the maintenance and custody by the Servicer as
custodian of the Financed Student Loan Files where the final determination that
any such improper act or omission by the Servicer resulted in such loss,
liability or expense is established by a court of law, by an arbitrator or by
way of settlement agreed to by the Servicer; provided, however, that the
Servicer shall not be liable to the Eligible Lender Trustee for any portion of
any such amount resulting from the willful misfeasance, bad faith or negligence
of the Eligible Lender Trustee and the Servicer shall not be liable to the
Indenture Trustee for any portion of any such amount resulting from the willful
misfeasance, bad faith or negligence of the Indenture Trustee. This provision,
as it relates to PHEAA, shall not be construed to limit the sovereign immunity
of the Commonwealth of Pennsylvania or the Servicer's or any other party's
rights, obligations, liabilities, claims or defenses which arise as a matter of
law or pursuant to any other provision of this Agreement.

                  SECTION 3.07. Effective Period and Termination. Each of
PHEAA's and EFS's appointment as custodian shall become effective as of the
Closing Date and shall continue in full force and effect for so long as PHEAA
and EFS, respectively, shall remain a Servicer hereunder. If PHEAA, EFS or any
successor Servicer shall resign as Servicer in accordance with the



                                      -10-
<PAGE>   15



provisions of this Agreement or if all the rights and obligations of PHEAA, EFS
or any such successor Servicer shall have been terminated under Section 8.01,
the appointment of PHEAA, EFS or such successor Servicer as custodian shall be
terminated simultaneously with the effectiveness of such termination. As soon as
practicable on or after any termination of such appointment (and in any event
within (i) 10 Business Days, with respect to that portion of the Financed
Student Loan Files it holds consisting of electronic records and information,
and (ii) 30 Business Days, with respect to the remaining portion of the Financed
Student Loan Files it holds), such Servicer shall deliver the Financed Student
Loan Files it holds to the Indenture Trustee or the Indenture Trustee's agent at
such place or places as the Indenture Trustee may reasonably designate.

                  SECTION 3.08. Schedule of Financed Student Loans. Schedules A
and B hereto shall indicate by name the Servicer whose obligation it is to
service each Financed Student Loan set forth on each such schedule. Such
indication shall be conclusive evidence of the applicable Servicer's obligation
to service such Financed Student Loans absent manifest error.

                                   ARTICLE IV

             Administration and Servicing of Financed Student Loans

                  SECTION 4.01. Duties of Servicers. Unless otherwise specified,
all references to actions to be taken by "the Servicer" under this Article IV or
any other provision of this Agreement with respect to Financed Student Loans or
with respect to Financed Student Loan Files shall be deemed to refer to actions
to be taken by each Servicer with respect to Financed Student Loans serviced by
such Servicer, as specified on Schedules A and B hereto, or with respect to
Financed Student Loan Files held by such Servicer. In addition, unless otherwise
specified, all references to actions previously taken by "the Servicer" under
this Article IV or any other provision of this Agreement with respect to
Financed Student Loans or with respect to Financed Student Loan Files shall be
deemed to refer to actions previously taken by the related Servicer with respect
to such Financed Student Loan or Financed Student Loans or with respect to
Financed Student Loan Files. Further, unless otherwise specified, all references
to actions to be taken by "the Servicer" under this Article IV or any other
provision of this Agreement with respect to a Trust Account or the preparation
or delivery of any report or Officers' Certificate shall be deemed to refer to
actions to be taken by each Servicer with respect to such Trust Account or
preparation or delivery of such report or Officers' Certificate, and all
references to actions previously taken by "the Servicer" under this Article IV
or any other provision of this Agreement with respect to a Trust Account or the
preparation or delivery of any report or Officers' Certificate shall be deemed
to refer to actions previously taken by the related Servicer with respect to
such Trust Account or preparation or delivery of such report or Officers'
Certificate. Consistent with the foregoing, but only insofar as the context so
permits, this Article IV is to be read with respect to each Servicer as if such
Servicer alone were servicing and administering its respective Financed Student
Loans hereunder. Further still, unless otherwise specified, all references to
"the Servicer" under this Article IV or any other provision of this Agreement
with respect to representations, warranties or covenants of the Servicer shall
be deemed to refer to representations, warranties or covenants made by each
Servicer, except that 


                                      -11-
<PAGE>   16



representations, warranties or covenants with respect to the Financed Student
Loans are hereby made by each Servicer only with respect to the Financed Student
Loans it services. Further still, unless otherwise specified, all references to
"the Servicer" in Sections 7.01, 7.02, 7.03, 7.04, 8.01 and 11.02 shall be
references to each Servicer as if each Servicer was referred to alone.

                  The Servicer, for the benefit of the Issuer (to the extent
provided herein), shall manage, service, administer and make collections on the
Financed Student Loans with reasonable care, using that degree of skill and
attention that the Servicer exercises with respect to all comparable student
loans that it services. 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 Financed Student Loans
(other than collection of any Interest Subsidy Payments and Special Allowance
Payments, which the Eligible Lender Trustee will perform on behalf of the Trust)
in accordance with, and otherwise comply with, all applicable Federal and state
laws, including all applicable standards, guidelines and requirements of the
Higher Education Act (in the case of the Financed Federal Loans) and any
Guarantee Agreement (in the case of all the Financed Student Loans), the failure
to comply with which would adversely affect the eligibility of one or more of
the Financed Federal Loans for federal reinsurance or Interest Subsidy Payments
or Special Allowance Payments or one or more of the Financed Student Loans for
receipt of Guarantee Payments or would have an adverse effect on the holders of
Certificates or the holders of Notes. In addition, without limiting the
generality of the foregoing, the Servicer shall service the Financed Student
Loans in accordance with the provisions of the Supplemental Sale and Servicing
Agreement. The Servicer also hereby acknowledges that its obligation to service
the Financed Student Loans includes those Additional Student Loans conveyed by
the Seller to the Eligible Lender Trustee on behalf of the Trust pursuant to
Section 2.02 and the related Transfer Agreement, a copy of which shall be
delivered to the Servicer by the Seller promptly upon execution thereof;
provided that any failure by the Seller to so deliver a Transfer Agreement shall
not affect the Servicer's obligations hereunder to service all the Financed
Student Loans.

                  The Servicer's duties shall include collection and posting of
all payments, responding to inquiries of borrowers on such Financed Student
Loans, monitoring borrowers' status, making required disclosures to borrowers,
investigating delinquencies, sending payment coupons to borrowers and otherwise
establishing repayment terms, reporting tax information to borrowers, if
applicable, accounting for collections and furnishing monthly and annual
statements with respect thereto to the Administrator. Subject to the provisions
of Section 4.02, 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 holders of Certificates and the holders of Notes 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
Financed Student Loans; provided, however, that the Servicer agrees that it will
not (a) permit any rescission or cancellation of a Financed 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 or (b) 


                                      -12-
<PAGE>   17



reschedule, revise, defer or otherwise compromise with respect to payments due
on any Financed Student Loan except pursuant to any applicable deferral or
forbearance periods or otherwise in accordance with all applicable standards,
guidelines and requirements of the Higher Education Act, any Guarantee Agreement
or the Programs with respect to the servicing of the Financed Student Loans and
except as otherwise permitted in accordance with Section 4.14; provided further,
however, that the Servicer shall not agree to any decrease of the interest rate
on, or the principal amount payable with respect to, any Financed Student Loan
except in accordance with the applicable standards, guidelines and requirements
of the Higher Education Act, any Guarantee Agreement or the Programs and as
otherwise permitted in accordance with Section 4.14. The Eligible Lender Trustee
on behalf of the Issuer hereby grants a power of attorney and all necessary
authorization to each Servicer to maintain any and all collection procedures
with respect to the Financed Student Loans it services, including filing,
pursuing and recovering claims against the Guarantors for Guarantee Payments and
taking any steps to enforce such Financed Student Loan such as commencing a
legal proceeding to enforce a Financed Student Loan in the name of the Issuer,
the Eligible Lender Trustee, the Indenture Trustee, the holders of Certificates
or the holders of Notes. The Eligible Lender Trustee or the Indenture Trustee
shall upon the written request of the Servicer or the Administrator furnish the
Servicer or the Administrator with any other powers of attorney and other
documents reasonably necessary or appropriate to enable the Servicer or the
Administrator to carry out their servicing and administrative duties hereunder.

                  SECTION 4.02. Collection of Financed Student Loan Payments.
(a) The Servicer shall make reasonable efforts (including all efforts that may
be specified under the Higher Education Act or any Guarantee Agreement) to
collect all payments called for under the terms and provisions of the Financed
Student Loans as and when the same shall become due and shall follow such
collection procedures as it follows with respect to all comparable student loans
that it services. The Servicer shall allocate collections with respect to the
Financed Student Loans between principal and interest in accordance with Section
5.03. With the written consent of the Administrator, 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 Financed Student Loan.

                  (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 Financed 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 all comparable guarantee agreements and student loans that it
services. In connection therewith, the Servicer is hereby authorized and
empowered to convey to any Guarantor the note and the related Financed Student
Loan File representing any Financed 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.

                  (c) The Eligible Lender Trustee shall, with the assistance of
the Administrator as set forth below and on behalf of the Issuer, make
reasonable efforts to claim, pursue and collect all Interest Subsidy Payments
and Special Allowance Payments from the Department 


                                      -13-
<PAGE>   18



with respect to any of the Financed Federal Loans as and when the same shall
become due and payable, shall comply with all applicable laws and agreements
with respect to claiming, pursuing and collecting such payments and shall follow
such practices and procedures as the Administrator follows with respect to its
own student loans. All amounts so collected by the Eligible Lender Trustee shall
constitute Available Funds for the applicable Collection Period and shall be
deposited into the Collection Account in accordance with Section 5.02. In
connection therewith, the Administrator shall prepare and file with the
Department on a timely basis all claims forms and other documents and filings
necessary or appropriate in connection with the claiming of Interest Subsidy
Payments and Special Allowance Payments on behalf of the Eligible Lender Trustee
and shall otherwise assist the Eligible Lender Trustee in pursuing and
collecting such Interest Subsidy Payments and Special Allowance Payments from
the Department. The Eligible Lender Trustee shall upon the written request of
the Administrator furnish the Administrator with any power of attorney and other
documents reasonably necessary or appropriate to enable the Administrator to
prepare and file such claims forms and other documents and filings.

                  The Eligible Lender Trustee may permit trusts, other than the
Trust, established by the Seller to securitize student loans to use the
Department lender identification number applicable to the Trust. In such event,
the Eligible Lender Trustee may claim and collect Interest Subsidy Payments and
Special Allowance Payments with respect to Financed Student Loans in the Trust
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 or any Federal Guarantor to any such other trust using such common
lender identification number as a result of amounts (including, but not limited
to, the Federal Consolidation Loan Rebate) owing to the Department or any
Federal Guarantor from the Trust will be deemed for all purposes hereof and of
the Basic Documents (including for purposes of determining amounts paid by the
Department or any Federal Guarantor with respect to the student loans in the
Trust and such other trust) to have been assessed against the Trust and shall be
deducted by the Eligible Lender Trustee 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 Trust. If so specified in the servicing
agreement applicable to any such other trust, any amounts assessed against
payments due from the Department or any Federal Guarantor to the Trust as a
result of amounts owing to the Department or any Federal Guarantor 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 Eligible
Lender Trustee 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 Trust.

                  SECTION 4.03. Realization upon Financed Student Loans. For the
benefit of the Issuer, the Servicer shall use reasonable efforts consistent with
its customary servicing practices and procedures and including all efforts that
may be specified under the Higher Education Act or any Guarantee Agreement in
its servicing of any delinquent Financed Student Loans.


                                      -14-
<PAGE>   19



                  SECTION 4.04. Computation of Note Interest Rate and
Certificate Rate. Prior to each Determination Date, the Administrator shall
determine each Note Interest Rate and the Certificate Rate that will be
applicable to the Distribution Date following such Determination Date, in
compliance with its obligation to prepare and deliver an Administrator's
Certificate on such Determination Date pursuant to Section 4.08. In connection
therewith, the Administrator shall calculate the T-Bill Rate in accordance with
the definition thereof calculate Three-Month LIBOR in accordance with the
definition thereof and shall also determine the Student Loan Rate with respect
to such Distribution Date; provided, however, that no such calculation of the
Student Loan Rate shall be required to be made unless the T-Bill Rate or
Three-Month LIBOR for such Interest Period is 100 basis points greater than the
T-Bill Rate of the preceding Determination Date or Three-Month LIBOR of the
preceding Determination Date, respectively, or with respect to T-Bill Indexed
Securities only, the 52 Week Treasury Bill Rate is 100 basis points less than
the T-Bill Rate as of such Determination Date.

                  SECTION 4.05. No Impairment. The Servicer shall not impair the
rights of the Issuer, the Eligible Lender Trustee, the Indenture Trustee, the
holders of Certificates or the holders of Notes in such Financed Student Loans.

                  SECTION 4.06. Purchase of Financed Student Loans;
Reimbursement. The Servicer or the Eligible Lender Trustee shall inform the
other party as well as the Indenture Trustee and the Seller promptly, in
writing, upon the discovery of any breach pursuant to Section 4.01, 4.02, 4.03
or 4.05. Unless the breach shall have been cured within 60 days following such
discovery (or, at the Servicer's election, the last day of the first month
following such discovery), the Servicer shall purchase any Financed Student Loan
in which the interests of the holders of Notes or the holders of Certificates
are materially and adversely affected by such breach as of the first day
succeeding the end of such 60-day period that is the last day of a Collection
Period (it being understood that any such breach that does not affect any
Guarantor's obligation to guarantee payment of such Financed Student Loan in
accordance with Guarantee Agreements will not be considered to have a material
adverse effect for this purpose). If the Servicer takes any action or fails to
take any action during any Collection Period pursuant to the sections referred
to above that impairs the rights of the Issuer, the Indenture Trustee, the
Eligible Lender Trustee, the holders of Certificates or the holders of Notes in
any Financed Student Loan or otherwise than as provided in such sections, the
Servicer shall purchase such Financed Student Loan as of the last day of such
Collection Period. In consideration of the purchase of any such Financed Student
Loan pursuant to either of the two preceding sentences, the Servicer shall remit
the Purchase Amount in the manner specified in Section 5.04. In addition, if any
such breach by the Servicer does not trigger such a purchase obligation but does
result in the refusal by a Federal Guarantor to guarantee all or a portion of
the accrued interest, or the loss (including any obligation of the Issuer to
repay to the Department) of certain Interest Subsidy Payments and Special
Allowance Payments, with respect to a Financed Federal Loan, then, unless such
breach, if curable, is cured within 60 days, the Servicer shall reimburse the
Issuer by remitting an amount equal to the sum of all such non-guaranteed
interest amounts and such forfeited Interest Subsidy Payments and Special
Allowance Payments in the manner specified in Section 5.04. Subject to Section
7.02, the sole remedy of the Issuer, the Eligible Lender Trustee, the Indenture
Trustee, the holders of Certificates and the holders of Notes with respect to a
breach pursuant to 


                                      -15-
<PAGE>   20



Section 4.01, 4.02, 4.03 or 4.05 shall be to require the Servicer to purchase
Financed Student Loans or to reimburse the Issuer as provided above 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 Financed Student Loan or the reimbursement for any interest
penalty pursuant to this Section 4.06.

                  SECTION 4.07. Servicing Fee; Excess Servicing Fee. The
Servicing Fee for each calendar month payable on each Monthly Servicing Payment
Date and any Excess Servicing Fees payable on any Distribution Date shall be
equal to the amounts determined by reference to the schedule of fees as set
forth in the PHEAA Fee Schedule and the EFS Fee Schedule. Notwithstanding
anything to the contrary contained herein or in any other Basic Document, the
Servicer shall only be entitled to receive any Excess Servicing Fee on any
Distribution Date if and to the extent that sufficient funds are available
pursuant to Section 5.05(c)(ix).

                  SECTION 4.08. Administrator's Certificate; Servicer's Report.
(a) On or before (i) the seventh day of each month (or, if any such day is not a
Business Day, on the next succeeding Business Day), the Servicer shall deliver
to the Seller a Servicer's Report with respect to the preceding calendar month
containing all information necessary for the preparation of the applicable
Transfer Agreement (including Schedule A), and (ii) the Closing Date or the
fifteenth day of each month (or, if any such day is not a Business Day, on the
next succeeding Business Day) or any other Transfer Date, the Servicer shall
deliver to the Administrator a Servicer's Report with respect to the preceding
calendar month containing all information necessary for the Administrator's

Servicer or the Administrator, as the case may be, dated as of December 31 of

or the Administrator, as the case may be, during the preceding 12-month period
(or, in the case of the first such certificate, during the period from the
Closing Date to December 31, 1999) and of its performance under this Agreement
has been made under such officers' supervision and (ii) to the best of such
officers' knowledge, based on such review, the Servicer or the Administrator, as
the case may be, has fulfilled all its obligations under this Agreement, or
under this Agreement and the Administration Agreement, respectively, throughout
such year or, if there has been a default in the fulfillment of any such
obligation, specifying each such default known to such officers and the nature
and status thereof. The Indenture Trustee shall send a copy of each such
Officers' Certificate and each report referred to in Section 4.10 to the Rating
Agencies. A copy of each such Officers' Certificate and each report referred to
in Section 4.10 may be obtained by any holder of Certificates, Certificate
Owner, holder of Notes or Note Owner by a request in writing to the Eligible
Lender Trustee addressed to its Corporate Trust Office, together with evidence

foregoing parties. Upon the telephone request of the Eligible Lender Trustee,

                  (b) The Servicer shall deliver to the Eligible Lender Trustee,

having obtained knowledge thereof, but in no event later than five Business Days

Servicer Default with respect to such Servicer under Section 8.01(a)(1) or (2).

                  (c) The Administrator shall deliver to the Eligible Lender
Trustee, the Indenture Trustee, the Servicer and the Rating Agencies, promptly
after having obtained knowledge thereof, but in no event later than five
Business Days thereafter, written notice in an Officers' Certificate of the
Administrator of any event which with the giving of notice or lapse of time, or
both, would become an Administrator Default under Section 8.01(b)(1) or (2) or
would cause Key Bank USA, National Association, to fail to meet any Rating
Agency Condition pursuant to Section 5.02(iii).

                  SECTION 4.10. Annual Independent Certified Public Accountants'
Report. Each of the Servicer and the Administrator shall cause a firm of
independent certified public accountants, which may also render other services
to the Servicer or the Administrator, as the case may be, to deliver to the
Seller, the Eligible Lender Trustee and the Indenture Trustee on or before March
30 of each year beginning March 30, 2000, (a) a report expressing a summary of
findings based upon a comparison of the mathematical calculations of certain

<PAGE>   22



in the Servicer's Reports during the preceding calendar year (or, in the case of
the first such report, the period from the Closing Date to December 31, 1999)
with the Servicer's computer reports that were the source of such amounts and a
report with regard to the assertions by the Servicer's management about the
Servicer's compliance with this Agreement during the preceding calendar year
(or, in the case of the first such report, the period from the Closing Date to
December 31, 1999) and (b) a report addressed to the Servicer, the Seller, the
Eligible Lender Trustee, the Indenture Trustee and each Rating Agency to the
effect that (i) such accountants have relied upon the assertions by the
Servicer's management about the Servicer's compliance with this Agreement during
the preceding calendar year (or, in the case of the first such report, during
the period from the Closing Date to December 31, 1999) and (ii) in such
accountants' opinion, such assertions are fairly stated in all material
respects, except for such exceptions as such firm shall believe to be immaterial
and such other exceptions as shall be set forth in such report. In the event
such firm requires the Indenture Trustee and the Eligible Lender Trustee to
agree to the procedures performed by such firm, the Servicer shall direct the
Indenture Trustee in writing to so agree; it being understood and agreed that
the Indenture Trustee and the Eligible Lender Trustee will deliver such letter
of agreement in conclusive reliance upon the direction of the Servicer, and the
Indenture Trustee and the Eligible Lender Trustee make no independent inquiry or
investigation as to, and shall have no obligation or liability in respect of,
the sufficiency, validity or correctness of such procedures.

                  Such report will also indicate that the firm is independent of
the Servicer or the Administrator, as the case may be, within the meaning of the
Code of Professional Ethics of the American Institute of Certified Public
Accountants.

                  SECTION 4.11. Access to Certain Documentation and Information
Regarding Financed Student Loans. Upon reasonable prior notice, the Servicer
shall provide to the holders of Certificates and the holders of Notes access to
the Financed Student Loan Files in such cases where the holders of Certificates
or the holders of Notes shall be required by applicable statutes or regulations
to review such documentation, as demonstrated by evidence satisfactory to the
Servicer in its reasonable judgment. Access shall be afforded 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 4.12. Servicer and Administrator Expenses. Each
Servicer and the Administrator shall be severally required to pay all expenses
incurred by it in connection with its activities hereunder, including fees and
disbursements of independent accountants, taxes imposed on such Servicer or the
Administrator, as the case may be, and expenses incurred in connection with
distributions and reports to the Administrator or to the holders of Certificates
and the holders of Notes, as the case may be.

                  SECTION 4.13. Appointment of Subservicer. Each Servicer may at
any time, upon the written consent of the Administrator, appoint a subservicer
to perform all or any portion 



                                      -18-
<PAGE>   23



of its obligations as Servicer hereunder; provided, however, that the Rating
Agency Condition shall have been satisfied in connection therewith; provided
further that each Servicer shall remain obligated and be liable to the Issuer,
the Eligible Lender Trustee, the Indenture Trustee, the holders of Certificates
and the holders of Notes for the servicing and administering of the Financed
Student Loans it services, as specified on Schedules A and B hereto 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 Financed Student Loans it services. The fees and
expenses of the subservicer shall be as agreed between the applicable Servicer
and its subservicer from time to time and none of the Issuer, the Eligible
Lender Trustee, the Indenture Trustee, the holders of Certificates or the
holders of Notes shall have any responsibility therefor.

                  SECTION 4.14. Special Programs. The Servicer shall offer
borrowers of the Financed Student Loans all special incentive programs, whether
or not in existence as of the date of this Agreement, generally offered to the
obligors of comparable loans owned by the Seller; provided, however, that to the
extent such programs are not required by the Higher Education Act (in the case
of the Financed Federal Loans) and have the effect of reducing the yield on the
Financed Student Loans (either by reducing borrower payments or reducing
principal balance), such special programs shall be applied to borrowers of
Financed Student Loans only if and to the extent the Issuer receives payment
from the Seller in an amount sufficient to offset such reduction of yield netted
against any payments owed by the Trust to the Seller pursuant to this Agreement.

                Statements to Certificateholders and Noteholders

                  SECTION 5.01. Establishment of Trust Accounts. (a) (i) The
         Administrator, for the benefit of the Issuer, shall establish and
         maintain in the name of the Indenture Trustee an Eligible Deposit
         Account (the "Collection Account"), bearing a designation clearly
         indicating that the funds deposited therein are held for the benefit of
         the Issuer. The Collection Account will initially be established as a
         segregated trust account at KeyBank National Association in the name of
         the Indenture Trustee. The Seller will make an initial deposit into the
         Collection Account on the Closing Date of cash or certain Eligible
         Investments equal to $6,614,533.55.

                  (ii) The Administrator, for the benefit of the Issuer, shall
         establish and maintain in the name of the Indenture Trustee an Eligible
         Deposit Account (the "Reserve Account"), bearing a designation clearly
         indicating that the funds deposited therein are held for the benefit of
         the Issuer. The Reserve Account will initially be established as a
         segregated trust account at KeyBank National Association in the name of
         the Indenture Trustee.

                  (iii) The Administrator, for the benefit of the Issuer, shall
         establish and maintain in the name of the Indenture Trustee an Eligible
         Deposit Account (the "Pre-Funding Account"), bearing a designation
         clearly indicating that the funds deposited therein are held for the
         benefit of the Issuer. The Pre-Funding Account will initially be
         established as a segregated trust account at KeyBank National
         Association in the name of the Indenture Trustee.

                  (iv) The Administrator, for the benefit of the Issuer, shall
         establish and maintain in the name of the Indenture Trustee an Eligible
         Deposit Account (the " Escrow Account"), bearing a designation clearly
         indicating that the funds deposited therein are held for the benefit of
         the Issuer. The Escrow Account will initially be established as a
         segregated trust account at KeyBank National Association in the name of
         the Indenture Trustee.

                  (b) Funds on deposit in the Collection Account, the Reserve
Account, the Pre-Funding Account and the Escrow Account (collectively, the
"Trust Accounts") shall be invested by the Indenture Trustee (or any custodian
or designated agent with respect to any amounts on deposit in such accounts) in
Eligible Investments pursuant to written instructions by the Administrator;
provided, however, it is understood and agreed that neither the Administrator
nor the Indenture Trustee shall be liable for any loss arising from such
investment in Eligible Investments. All such Eligible Investments shall be held
by (or by any custodian on behalf of) the Indenture Trustee for the benefit of
the Issuer; provided that on the Business Day preceding each Distribution Date
all interest and other investment income (net of losses and investment expenses)
on funds on deposit therein shall be deposited into the Collection Account and
shall be deemed to constitute a portion of the Available Funds for such
Distribution Date. Other than as described in the following proviso or as
otherwise permitted by the Rating Agencies, funds on deposit in the Trust
Accounts shall be invested in Eligible Investments that will mature so that such
funds will be available at the close of business on the Business Day preceding
the following Distribution Date; provided, however, that funds on deposit in
Trust Accounts may be invested in Eligible Investments of the Indenture Trustee
which may mature so that such funds will be available on such Distribution Date.
Funds deposited in a Trust Account on a Business Day which immediately precedes
a Distribution Date upon the maturity of any Eligible Investments are not
required to be invested overnight.

                  (c) (i) The Indenture Trustee shall possess all right, title
         and interest in all funds on deposit from time to time in the Trust
         Accounts and in all proceeds thereof (including all income thereon) and
         all such funds, investments, proceeds and income shall be part of the
         Trust Estate. Subject to the Administrator's power to instruct the
         Indenture Trustee pursuant to paragraph (b) above and paragraph
         (c)(iii) below, the Trust Accounts shall be under the sole dominion and
         control of the Indenture Trustee for the benefit of the Issuer. If, at
         any time, any of the Trust Accounts ceases to be an Eligible Deposit
         Account, the Indenture Trustee (or the Administrator on its behalf)
         agrees, by its acceptance hereto, that it shall within 10 Business Days
         (or such longer period, not to exceed 30 calendar days, as to which
         each Rating Agency may consent) establish a new 



                                      -20-
<PAGE>   25



         Trust Account as an Eligible Deposit Account and shall transfer any
         cash and/or any investments to such new Trust Account. In connection
         with the foregoing, the Administrator agrees that, in the event that
         any of the Trust Accounts are not accounts with the Indenture Trustee,
         the Administrator shall notify the Indenture Trustee in writing
         promptly upon any of such Trust Accounts ceasing to be an Eligible
         Deposit Account.

                  (ii) With respect to the Trust Account Property, the Indenture
         Trustee agrees, by its acceptance hereof, that:

                  (A) any Trust Account Property that is held in deposit
accounts shall be held solely in Eligible Deposit Accounts, subject to the last
sentence of Section 5.01(c)(i); and, subject to Section 5.01(b), each such
Eligible Deposit Account shall be subject to the exclusive custody and control
of the Indenture Trustee, and the Indenture Trustee shall have sole signature
authority with respect thereto;

                  (B) any Trust Account Property shall be Delivered to the
Indenture Trustee in accordance with the definition of "Delivery" and shall be
held, pending maturity or disposition, solely by the Indenture Trustee or such
other Person acting solely for the Indenture Trustee as required for Delivery;

                  (C) In the event that the Indenture Trustee, in its capacity
as securities intermediary has or subsequently obtains by agreement, operation
of law or otherwise a security interest in the Trust Accounts or any security
entitlement credited thereto, the Indenture Trustee, in its capacity as
securities intermediary hereby agrees that such security interest shall be
subordinate to the security interest of the Indenture Trustee. The financial
assets and other items deposited to the Trust Accounts will not be subject to
deduction, set-off, banker's lien, or any other right in favor of any person
other than the Indenture Trustee (except that the Indenture Trustee, in its
capacity as securities intermediary may set off (i) all amounts due to it in
respect of its customary fees and expenses for the routine maintenance and
operation of the Trust Accounts, and (ii) the face amount of any checks which
have been credited to the Trust Accounts but are subsequently returned unpaid
because of uncollected or insufficient funds).

                  (iii) The Administrator shall have the power, revocable for
         cause or upon the occurrence and during the continuance of an
         Administrator Default by the Indenture Trustee or by the Eligible
         Lender Trustee with the consent of the Indenture Trustee, to instruct
         the Indenture Trustee to make withdrawals and payments from the Trust
         Accounts for the purpose of permitting the Servicers, the Administrator
         or the Eligible Lender Trustee to carry out its respective duties
         hereunder or permitting the Indenture Trustee to carry out its duties
         under the Indenture.

                  SECTION 5.02. Collections. The Servicer shall remit within two
Business Days of receipt thereof to the Collection Account all payments by or on
behalf of the Obligors with respect to the Financed Student Loans (other than
Purchased Student Loans), and all Liquidation Proceeds, as collected during the
Collection Period. Notwithstanding the foregoing, for so long as (i) Key Bank
USA, National Association remains the Administrator, (ii) no Administrator



                                      -21-
<PAGE>   26



Default shall have occurred and be continuing and (iii) prior to ceasing daily
remittances to the Collection Account, the Rating Agency Condition shall have
been satisfied (and any conditions or limitations imposed by the Rating Agencies
in connection therewith are complied with), the Servicer shall remit such
collections within two Business Days of receipt thereof to the Administrator,
and the Administrator need not deposit such collections into the Collection
Account until one Business Day immediately prior to the next following
Distribution Date; provided, however, that, notwithstanding the foregoing, on or
before the Business Day preceding each Monthly Servicing Payment Date that is
not a Distribution Date, the Administrator shall deposit into the Collection
Account (i) Guarantee Payments made by TERI in excess of the Maximum TERI
Payments Amount and (ii) that portion of such amounts received by it that is
equal to the Servicing Fee payable on such date. In the event that any of the
foregoing conditions for ceasing daily remittances shall no longer be satisfied,
then the Administrator shall deposit all collections held by it into the
Collection Account within five Business Days thereof. For purposes of this
Article V, the phrase "payments by or on behalf of Obligors" shall mean payments
made with respect to the Financed Student Loans by or on behalf of borrowers
thereof and the Guarantors (but excluding the Department).

                  SECTION 5.03. Application of Collections. (a) With respect to
each Financed Student Loan, all collections (including all Guarantee Payments,
but subject to the Maximum TERI Payments Amount with respect to TERI Guarantee
Payments) with respect thereto for the Collection Period shall be applied to
interest and principal on such Financed Student Loan by the Servicer in
accordance with its customary practice by allocating to interest (i) any late
payment charge or any similar fee received with respect to such Financed Student
Loan and (ii) the portion of such collection equal to the product of (A) the
applicable interest rate on such Financed Student Loan, (B) the unpaid principal
balance of such Financed Student Loan and (C) the period of time elapsed since
the preceding payment of interest on such Financed Student Loan was made (over
the actual number of days in a year) ("Interest Collections") and by allocating
the remainder of such collection to principal.

                  (b) All Liquidation Proceeds shall be applied to the related
Financed Student Loan.

                  SECTION 5.04. Additional Deposits. (a) Within two Business
Days after receipt thereof, the Eligible Lender Trustee shall deposit in the
Collection Account the aggregate amount of Interest Subsidy Payments and Special
Allowance Payments received by it with respect to the Financed Federal Loans.
The Servicer shall deposit or cause to be deposited in the Collection Account
the aggregate Purchase Amount with respect to Purchased Student Loans and all
other amounts to be paid by the Servicer under Section 4.06 when such amounts
are due, and the Seller shall deposit or cause to be deposited therein the
aggregate Purchase Amount with respect to Purchased Student Loans and all other
amounts to be paid by the Seller under Sections 3.02 and 9.01 when such amounts
are due.

                  (b) Notwithstanding anything to the contrary set forth in
paragraph (a) above, if daily deposits to the Collection Account are not
required pursuant to Section 5.02, the Eligible Lender Trustee, the Seller and
the Servicer shall pay the amounts referred to in paragraph (a)



                                      -22-

above that would otherwise be deposited into the Collection Account to the
Administrator. The Administrator shall not be required to deposit such amounts
into the Collection Account until the Business Day preceding each Distribution
Date.

                  SECTION 5.05. Distributions. (a) On each Determination Date,
the Administrator shall calculate all amounts required to determine the amounts
to be deposited in the Collection Account from the other Trust Accounts and the
amounts to be distributed therefrom on the related Monthly Servicing Payment
Date or Distribution Date.

                  (b) On each Monthly Servicing Payment Date that is not a
Distribution Date, the Administrator shall instruct the Indenture Trustee (based
on the information contained in the Administrator's Officer's Certificate and
each related Servicer's report delivered pursuant to Section 4.08(a) and (b)) to
distribute (i) to the Seller any amounts on deposit in the Collection Account
which consist of Guarantee Payments made by TERI in excess of the Maximum TERI
Payments Amount and (ii) to the Servicers by 11:00 a.m. (New York time), from
and to the extent of the Available Funds on deposit in the Collection Account
the Servicing Fee due with respect to the preceding calendar month and all
unpaid Servicing Fees from prior months, and the Indenture Trustee shall comply
with such instructions.

                  (c) On each Distribution Date, the Administrator shall
instruct the Indenture Trustee (based on the information contained in the
Administrator's Certificate and each related Servicer's Report delivered
pursuant to Section 4.08(a) and (c)) to make the following deposits and
distributions to the Persons or to the account specified below by 11:00 a.m.
(New York time), to the extent of the amount of Available Funds in the
Collection Account, in the following order of priority and the Indenture Trustee

         Account which consist of Guarantee Payments made by TERI in excess of
         the Maximum TERI Payments Amount;

                  (ii) to the Servicers, the Servicing Fee due with respect to

         of Available Funds remaining after the application of clauses (i)
         through (vii), the Certificateholders' Principal Distribution Amount;

         application of clauses (i) through (ix), the aggregate unpaid amount of
         Noteholders' Interest Index Carryover, if any;

Amount has not been reduced to zero, the Administrator shall instruct the
Indenture Trustee pursuant to Section 4.08(c) to withdraw from the Subsequent
Pool Pre-Funding Subaccount on the first Distribution Date the remaining
Subsequent Pool Pre-Funded Amount on deposit in such subaccount and, (x) if such
amount is greater than $10,000,000, distribute the applicable Noteholders'
Percentage of such amount to the holders of Class A-1 Notes and Class A-2 Notes

Association of this Agreement and the performance by Key Bank USA, National
Association of the transactions contemplated by this Agreement, and in
connection with the execution and delivery by the Administrator of the

excluded from the Seller's responsibilities pursuant to Section 6.03(a) above).

resignation or removal of the Eligible Lender Trustee or the Indenture Trustee
and the termination of this Agreement or the Indenture or the Trust Agreement,
as applicable, 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 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 the Seller, without interest.

                  SECTION 6.04. Liability of Administrator; Indemnities. The
Administrator shall be liable in accordance herewith only to the extent of the

the holders of Certificates and the holders of Notes and any of the officers,
directors, employees and agents of the Issuer, the Eligible Lender Trustee, the
Indenture Trustee and the Servicers from and against any and all costs,

such Person through, the negligence, willful misfeasance or bad faith of the
Administrator in the performance of its duties under this Agreement, the
Supplemental Sale and Servicing Agreement or the Administration Agreement or by
reason of reckless disregard of its obligations and duties hereunder or
thereunder.

Agreement and the Administration Agreement and shall include reasonable fees and
expenses of counsel and expenses of litigation. If the Administrator shall have
made any indemnity 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 Administrator,
without interest.

to this Agreement or to the Administration Agreement; provided, however, that

an agreement of assumption to perform every obligation of the Seller under this
Agreement or the Administrator under this Agreement and the Administration
Agreement, as the case may be, (ii) immediately after giving effect to such
transaction, no representation or warranty made pursuant to Section 3.01 or 6.01
shall have been breached and no Administrator Default, and no event that, after
notice or lapse of time, or both, would become an Administrator Default shall
have occurred and be continuing, (iii) the surviving Seller or Administrator, as
the case may be, if other than Key Bank USA, National Association (or affiliate
thereof), shall have delivered to the Eligible Lender Trustee and the 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, if any, provided for in
this 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) the surviving Seller or Administrator, as the case may be,
shall have a consolidated net worth at least equal to that of the predecessor
Seller or Administrator, as the case may be, (v) unless Key Bank USA, National
Association (or affiliate thereof) is the surviving entity, such transaction
will not result in a material adverse Federal or state tax consequence to the
Issuer, the holders of Notes or the holders of Certificates and (vi) unless Key
Bank USA, National Association (or affiliate thereof) is the surviving entity,
the Seller or the Administrator, as the case may be, shall have delivered to the
Eligible Lender Trustee and the Indenture Trustee an Opinion of Counsel either

continuation statements and amendments thereto have been executed and filed that
are necessary fully to preserve and protect the interest of the Eligible



                                      -35-

Lender Trustee and Indenture Trustee, respectively, in the Financed Student

opinion of such counsel, no such action shall be necessary to preserve and
protect such interests.

                  SECTION 6.06. Limitation on Liability of Seller, Administrator
and Others. (a) The Seller and any director or officer or employee or agent of
the Seller 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 3.02). 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 this Agreement, and that in its
opinion may involve it in any expense or liability.

                  (b) Neither the Administrator nor any of its directors,
officers, employees or agents shall be under any liability to the Issuer, the
holders of Notes or the holders of Certificates, the Indenture Trustee or the
Eligible Lender Trustee except as provided under this Agreement or the
Administration Agreement, for any action taken or for refraining from the taking
of any action pursuant to this Agreement or the Administration Agreement or for
errors in judgment; provided, however, that this provision shall not protect the
Administrator or any such person against any liability that would otherwise be
imposed by reason of willful misfeasance, bad faith or negligence in the
performance of duties or by reason of reckless disregard of obligations and
duties under this Agreement or under the Administration Agreement. The
Administrator and any of its directors, officers, employees or agents 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 or under the Administration Agreement.

                  Except as provided in this Agreement or the Administration
Agreement, the Administrator shall not be under any obligation to appear in,
prosecute or defend any legal action that shall not be incidental to its duties
to administer the Financed Student Loans and the Trust in accordance with this
Agreement and the Administration Agreement, and that in its opinion may involve
it in any expense or liability; provided, however, that the Administrator 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 holders of Certificates under this Agreement and the holders of
Notes under the Indenture.

                  SECTION 6.07. Seller May Own Certificates or Notes. The Seller
and any Affiliate thereof may in its individual or any other capacity become the
owner or pledgee of Certificates or Notes with the same rights as it would have

herein or in any other Basic Document.

                  SECTION 6.08. Key Bank USA, National Association Not To Resign
as Administrator. Subject to the provisions of Section 6.05, Key Bank USA,
National Association shall not resign from the obligations and duties imposed on
it as Administrator under this 



                                      -36-

Agreement and under the Administration Agreement except upon determination that
the performance of its duties under this Agreement and under the Administration
Agreement shall no longer be permissible under applicable law or shall violate
any final order of a court or administrative agency with jurisdiction over Key
Bank USA, National Association or its properties. Notice of any such
determination permitting the resignation of Key Bank USA, National Association
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

responsibilities and obligations of Key Bank USA, National Association in
accordance with Section 8.02.


                                   ARTICLE VII

                                  The Servicer

                  SECTION 7.01. Representations of Servicer. The Servicer makes
the following representations on which the Issuer is deemed to have relied in
acquiring (through the Eligible Lender Trustee) the Financed Student Loans and
appointing the Servicer as servicer hereunder. The representations speak as of
the execution and delivery of this Agreement and as of the Closing Date, in the
case of the Initial Financed Student Loans, and as of the applicable Transfer

Trustee on behalf of the Issuer and the pledge thereof to the Indenture Trustee
pursuant to the Indenture.

                  (a) Organization and Good Standing. The Servicer, in the case
of PHEAA, is duly organized and validly existing as an agency of the
Commonwealth of Pennsylvania and in the case of EFS, is duly organized and
validly existing as a corporation in the State of Indiana, in each case in good
standing under the laws of the state of its incorporation, with the power and
authority to own its properties and to conduct its business as such properties
are currently owned and such business is presently conducted, and had at all
relevant times, and has, the power, authority and legal right to service the
Financed Student Loans and to hold the Financed Student Loan Files as custodian.

                  (b) Due Qualification. The Servicer is duly qualified to do
business and has obtained all necessary licenses and approvals in all
jurisdictions in which the ownership or lease of property or the conduct of its
business (including the servicing of the Financed Student Loans as required by
this Agreement) shall require such qualifications.

                  (c) Power and Authority. The Servicer has the power and
authority to execute and deliver this Agreement and to carry out its terms; and
the execution, delivery and performance of this Agreement have been duly
authorized by the Servicer by all necessary



                                      -37-

action. No registration with or approval of any governmental agency (except, in
the case of PHEAA, for the approval as to form and legality by the Deputy
Attorney General for the Commonwealth of Pennsylvania, which approval is
evidenced by the approval memorandum attached hereto) is required for the due
execution and delivery by, and enforceability against, the Servicer of this
Agreement.

                  (d) Binding Obligation. This Agreement constitutes a legal,
valid and binding obligation of the Servicer enforceable in accordance with its
terms.

                  (e) No Violation. The consummation of the transactions
contemplated by this Agreement and the fulfillment of the terms hereof shall 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,
its enabling legislation, any applicable articles of incorporation or by-laws of
the Servicer, or any indenture, agreement or other instrument to which the
Servicer is a party or by which it shall be bound; nor result in the creation or
imposition of any Lien upon any of its properties pursuant to the terms of any
such indenture, agreement or other instrument (other than this Agreement); nor
violate any law or, to the best of the Servicer's knowledge, any order, rule or
regulation applicable to the Servicer of any court or of any Federal or state
regulatory body, administrative agency or other governmental instrumentality
having jurisdiction over the Servicer or its properties.

                  (f) No Proceedings. There are no proceedings or investigations
pending, or, to the Servicer's best knowledge, threatened, before any court,
regulatory body, administrative agency or other governmental instrumentality
having jurisdiction over the Servicer or its properties: (i) asserting the
invalidity of this Agreement, the Indenture, any of the other Basic Documents,
the Notes or the Certificates, (ii) seeking to prevent the issuance of the Notes
or the Certificates or the consummation of any of the transactions contemplated
by this Agreement, the Indenture or any of the other Basic Documents, (iii)
seeking any determination or ruling that could reasonably be expected to have a
material and adverse effect on the performance by the Servicer of its
obligations under, or the validity or enforceability of, this Agreement, the
Indenture, any of the other Basic Documents, the Notes or the Certificates or
(iv) relating to the Servicer and which might adversely affect the Federal or
state income tax attributes of the Notes or the Certificates.

                  (g) No Amendment or Waiver. No provision of a Financed Student
Loan has been waived, altered or modified in any respect, except pursuant to a
document, instrument or writing included in the Financed Student Loan File, and
no such amendment, waiver, alteration or modification causes such Financed
Student Loan not to conform to the other warranties contained in this Section or
those of the Seller contained in Section 3.01.

                  (h) Location of Financed Student Loan Files. The Financed
Student Loan Files are kept in the offices of the Servicer specified in Schedule
C hereto, or at such other office specified in accordance with Section 3.04(b).

                  SECTION 7.02. 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 attorney's fees, that may be imposed on, incurred by or
asserted against the Issuer, the Eligible Lender Trustee, the Indenture Trustee,
the Seller, the Administrator, the holders of Certificates or the holders of
Notes or any of the officers, directors, employees and agents of the Issuer, the
Eligible Lender Trustee, the Indenture Trustee, the Administrator or the Seller
to the extent that such loss, liability or expense arose out of, or was imposed
upon any such Person through, the negligence, willful misfeasance or bad faith
of the Servicer in the performance of its obligations and duties under this
Agreement or the Supplemental Sale and Servicing Agreement or by reason of the
reckless disregard of its obligations and duties under this Agreement or the
Supplemental Sale and Servicing Agreement, where the final determination that
any such loss, liability or expense arose out of, or was imposed upon any such
Person 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 and other disasters) to satisfy its obligations under
this Agreement or the Supplemental Sale and Servicing 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.
This provision shall not be construed to limit the sovereign immunity of the
Commonwealth of Pennsylvania (in the case of PHEAA) or the Servicer's or any
other party's rights, obligations, liabilities, claims or defenses which arise
as a matter of law or pursuant to any other provision of this Agreement.

                  For purposes of this Section, in the event of the termination
of the rights and obligations of PHEAA or EFS (or any successor thereto pursuant
to Section 7.03) as Servicer pursuant to Section 8.01(a), 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
8.02.

                  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 7.03. 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 



                                      -39-
<PAGE>   44



Servicer hereunder and under the Supplemental Sale and Servicing Agreement, (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 7.04. Limitation on Liability of Servicer and Others.
Neither the Servicer nor any of the directors, officers, employees or agents of
the Servicer shall be under any liability to the Issuer, the holders of Notes or
the holders of Certificates, except as provided under this Agreement or the
Supplemental Sale and Servicing Agreement, for any action taken or for
refraining from the taking of any action pursuant to this Agreement or the
Supplemental Sale and Servicing Agreement or for errors in judgment; provided,
however, that this provision shall not protect the Servicer or any such person
against any liability that would otherwise be imposed by reason of willful
misfeasance, bad faith or negligence in the performance of duties or by reason
of reckless disregard of obligations and duties under this Agreement or the
Supplemental Sale and Servicing Agreement. The Servicer and any director,
officer, employee or agent of 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 that
shall not be incidental to its duties to service the Financed Student Loans in
accordance with this Agreement and the Supplemental Sale and Servicing
Agreement, and that in its opinion may involve it in any expense or liability;
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 holders of Certificates under
this Agreement and the holders of Notes under the Indenture.

                  SECTION 7.05. Neither PHEAA Nor EFS To Resign as Servicer.
Subject to the provisions of Section 7.03, neither PHEAA nor EFS shall resign
from the obligations and duties hereby imposed on it as Servicer under this
Agreement and the Supplemental Sale and Servicing Agreement except upon
determination that the performance of its duties under this Agreement and the
Supplemental Sale and Servicing Agreement shall no longer be permissible under
applicable law. Notice of any such determination permitting the resignation of
PHEAA or EFS 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 



                                      -40-
<PAGE>   45


the Indenture Trustee or a Successor Servicer shall have assumed the
responsibilities and obligations of PHEAA or EFS in accordance with Section
8.02.

                  SECTION 8.01. Servicer Default; Administrator Default. (a)
Servicer Default. If any one of the following events (a "Servicer Default")
shall occur and be continuing:

                  (1) any failure by the Servicer (i) to deliver to the
Indenture Trustee for deposit in any of the Trust Accounts any payment required
by the Basic Documents or (ii) in the event that daily deposits into the
Collection Account are not required, to deliver to the Administrator any payment
required by the Basic Documents, which failure in case of either clause (i) or
(ii) continues unremedied for three Business Days after written notice of such
failure is received by the Servicer from the Eligible Lender Trustee, the
Indenture Trustee or the Administrator or after discovery of such failure by an
officer of the Servicer; or

                  (2) any failure by the Servicer duly to observe or to perform
in any material respect any other covenants or agreements of the Servicer set
forth in this Agreement or any other Basic Document, which failure shall (i)
materially and adversely affect the rights of the holders of Notes or the
holders of Certificates and (ii) continues unremedied for a period of 60 days
after the date on which written notice of such failure, requiring the same to be
remedied, shall have been given (A) to the Servicer by the Indenture Trustee,
the Eligible Lender Trustee, the other Servicer or the Administrator or (B) to
the Servicer, and to the Indenture Trustee and the Eligible Lender Trustee by
the holders of Notes or the holders of Certificates, as applicable, representing
not less than 25% of the Outstanding Amount of the Notes or 25% of the
outstanding Certificate Balance;

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

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

then, and in each and every case, so long as the Servicer Default shall not have
been remedied, either the Indenture Trustee, or the holders 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 holders of Notes) may terminate all the rights and
obligations (other than the obligations set forth in Section 7.02 hereof) of the
Servicer under this Agreement and the Supplemental Sale and Servicing Agreement.
On or after the receipt by the Servicer of such written notice, all authority
and power of the Servicer under this Agreement and the Supplemental Sale and
Servicing Agreement, whether with respect to the Notes, the Certificates or the
Financed Student Loans or otherwise, shall, without further action, pass to and
be vested in the Indenture Trustee or such successor 



                                      -41-

Servicer as may be appointed under Section 8.02; and, without limitation, the
Indenture Trustee and the Eligible Lender Trustee are hereby authorized and
empowered to execute and deliver, for the benefit of the predecessor Servicer,
as attorney-in-fact or otherwise, any and all documents and other instruments,
and to do or accomplish all other acts or things necessary or appropriate to
effect the purposes of such notice of termination, whether to complete the
transfer and endorsement of the Financed Student Loans and related documents, or
otherwise. 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 and the Supplemental Sale and Servicing 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 Financed Student Loan. All
reasonable costs and expenses (including attorneys' fees) incurred in connection
with transferring the Financed 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
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.

                  (b) Administrator Default. If any one of the following events
(an "Administrator Default") shall occur and be continuing:

                  (1) (i) in the event that daily deposits into the Collection
Account are not required, any failure by the Administrator to deliver to the
Indenture Trustee for deposit in any of the Trust Accounts any Available Funds
required to be paid on or before the Business Day immediately preceding any
Monthly Servicing Payment Date or Distribution Date, as applicable, or (ii) any
failure by the Administrator to direct the Indenture Trustee to make any
required distributions from any of the Trust Accounts, which failure in case of
either clause (i) or (ii) continues unremedied for three Business Days after
written notice of such failure is received by the Administrator from the
Indenture Trustee or the Eligible Lender Trustee or after discovery of such
failure by an officer of the Administrator; or

                  (2) any failure by the Administrator duly to observe or to
perform in any material respect any other covenants or agreements of the
Administrator set forth in this Agreement, the Administration Agreement or any
other Basic Document, which failure shall (i) materially and adversely affect
the rights of the holders of Notes or the holders of Certificates and (ii)
continues unremedied for a period of 60 days after the date on which written
notice of such failure, requiring the same to be remedied, shall have been given
(A) to the Administrator by the Indenture Trustee or the Eligible Lender Trustee
or (B) to the Administrator and to the Indenture Trustee and the Eligible Lender
Trustee by the holders of Notes or the holders of Certificates, as applicable,
representing not less than 25% of the Outstanding Amount of the Notes or 25% of
the outstanding Certificate Balance; or

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


                                      -42-
<PAGE>   47



then, and in each and every case, so long as the Administrator Default shall not
have been remedied, either the Indenture Trustee, or the holders of Notes
evidencing not less than 25% of the Outstanding Amount of the Notes, by notice
then given in writing to the Administrator (and to the Indenture Trustee and the
Eligible Lender Trustee if given by the holders of Notes) may terminate all the
rights and obligations (other than the obligations set forth in Section 6.04
hereof) of the Administrator under this Agreement, the Supplemental Sale and
Servicing Agreement and the Administration Agreement. On or after the receipt by
the Administrator of such written notice, all authority and power of the
Administrator under this Agreement, the Supplemental Sale and Servicing
Agreement and the Administration Agreement, whether with respect to Notes, the
Certificates or the Financed Student Loans or otherwise, shall, without further
action, pass to and be vested in the Indenture Trustee or such successor
Administrator as may be appointed under Section 8.02; and, without limitation,
the Indenture Trustee and the Eligible Lender Trustee are hereby authorized and
empowered to execute and deliver, for the benefit of the predecessor
Administrator, as attorney-in-fact or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination. The
predecessor Administrator shall cooperate with the successor Administrator, the
Indenture Trustee and the Eligible Lender Trustee in effecting the termination
of the responsibilities and rights of the predecessor Administrator under this
Agreement, the Supplemental Sale and Servicing Agreement and the Administration
Agreement. All reasonable costs and expenses (including attorneys' fees)
incurred in connection with amending this Agreement, the Supplemental Sale and
Servicing Agreement and the Administration Agreement to reflect such succession
as Administrator pursuant to this Section shall be paid by the predecessor
Administrator upon presentation of reasonable documentation of such costs and
expenses. Upon receipt of notice of the occurrence of a Administrator Default,
the Eligible Lender Trustee shall give notice thereof to the Rating Agencies.

                  SECTION 8.02. Appointment of Successor. (a) Upon receipt by a
Servicer or the Administrator, as the case may be, of notice of termination
pursuant to Section 8.01, or the resignation by a Servicer or the Administrator,
as the case may be, in accordance with the terms of this Agreement, the
predecessor Servicer or Administrator, as the case may be, shall continue to
perform its functions as Servicer or Administrator, as the case may be, under
this Agreement or under this Agreement and the Administration Agreement, as the
case may be, 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 later of
(x) the date 120 days from the delivery to the Eligible Lender Trustee and the
Indenture Trustee of written notice of such resignation (or written confirmation
of such notice) in accordance with the terms of this Agreement and (y) the date
upon which the predecessor Servicer or Administrator, as the case may be, shall
become unable to act as Servicer or Administrator, as the case may be, as
specified in the notice of resignation and accompanying Opinion of Counsel. In
the event of the termination hereunder of a Servicer or the Administrator, as
the case may be, the Issuer shall appoint a successor Servicer or Administrator,
as the case may be, acceptable to the Indenture Trustee, and the successor
Servicer or Administrator, as the case may be, shall accept its appointment by a
written assumption in form acceptable to the Indenture Trustee. In the event
that a successor Servicer or Administrator, as the case may be, has not been 
appointed at the time when the predecessor Servicer or Administrator, as the
case



                                      -43-
<PAGE>   48



may be, has ceased to act as Servicer or Administrator in accordance with this
Section, the Indenture Trustee without further action shall automatically be
appointed the successor Servicer or Administrator, as the case may be, and the
Indenture Trustee shall be entitled to the applicable portion of the Servicing
Fee and the applicable portion of any Excess Servicing Fees, or the
Administration Fee, as the case may be. 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 a Servicer under this Agreement or to the Administrator
under this Agreement and the Administration 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 obligations
otherwise imposed on it under the Basic Documents until such successor has in
fact assumed such appointment.

                  (b) Upon appointment, the successor Servicer or Administrator,
as the case may be (including the Indenture Trustee acting as successor Servicer
or Administrator, as the case may be), shall be the successor in all respects to
the predecessor Servicer or Administrator, as the case may be, and shall be
subject to all the responsibilities, duties and liabilities placed on the
predecessor Servicer or Administrator, as the case may be, that arise thereafter
or are related thereto and shall be entitled to an amount agreed to by such
successor Servicer or Administrator (which shall not exceed the applicable
portion of the Servicing Fee and the applicable portion of any Excess Servicing
Fees, or the Administration Fee, as the case may be, unless such compensation
arrangements will not result in a downgrading of Notes or the Certificates by
any Rating Agency) and all the rights granted to the predecessor Servicer or
Administrator, as the case may be, by the terms and provisions of this
Agreement.

                  (c) Neither the Servicer nor the Administrator may 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 or Administrator pursuant hereto and thereto, shall
be entitled to resign to the extent a qualified successor Servicer or
Administrator has been appointed and has assumed all the obligations of the
Servicer or the Administrator, as the case may be, in accordance with the terms
of this Agreement and the other Basic Documents.

                  SECTION 8.03. Notification to Noteholders and
Certificateholders. Upon any termination of, or appointment of a successor to, a
Servicer or the Administrator, as the case may be, pursuant to this Article
VIII, the Eligible Lender Trustee shall give prompt written notice thereof to
the holders of Certificates and the Indenture Trustee shall give prompt written
notice thereof to holders of Notes 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 8.04. Waiver of Past Defaults. The holders of Notes
evidencing not less than a majority of the Outstanding Amount of the Notes (or
the holders 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 holders of Notes) may, on 



                                      -44-
<PAGE>   49



behalf of all the holders of Notes and the holders of Certificates, waive in
writing any default by the Servicer in the performance of its obligations
hereunder, and any default by the Administrator in the performance of its
obligations hereunder and under the Administration Agreement, 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 or Administrator
Default arising therefrom shall be deemed to have been remedied for every
purpose of this Agreement and the Administration Agreement. No such waiver shall
extend to any subsequent or other default or impair any right consequent
thereto.


                                   ARTICLE IX

                                   Termination

                  SECTION 9.01. Termination. (a) Optional Purchase of All
Financed Student Loans. As of the last day of any Collection Period immediately
preceding a Distribution Date as of which the sum of the then outstanding Pool
Balance is 5% or less of the Initial Pool Balance, the Seller shall have the
option to purchase the Trust Estate, other than the Trust Accounts; provided,
however, that, unless Moody's agrees otherwise, the Seller may not effect any
such purchase so long as the rating on its long-term debt obligations is less
than Baa3 by Moody's, unless the Eligible Lender Trustee and the Indenture
Trustee shall have given notice to each of the Rating Agencies and shall have
received an Opinion of Counsel to the effect that such purchase would not
constitute a fraudulent conveyance. To exercise such option, the Seller shall
deposit pursuant to Section 5.04 in the Collection Account an amount equal to
the aggregate Purchase Amount for the Financed Student Loans and the related
rights with respect thereto, plus the appraised value of any such other property
held by the Trust other than the Trust Accounts, such value to be determined by
an appraiser mutually agreed upon by the Seller and the Eligible Lender Trustee,
and shall succeed to all interests in and to the Trust; provided, however, that
the Seller may not effect such purchase if the aggregate Purchase Amount to be
so deposited in the Collection Account does not equal or exceed an amount equal
to the sum of (i) the unpaid principal amount of the Notes then outstanding plus
accrued and unpaid interest thereon at the applicable Note Interest Rates to the
date of exercise and the amount of unpaid Noteholders' Interest Index Carryover
with respect thereto and (ii) the unpaid Certificate Balance, plus accrued and
unpaid interest thereon at the Certificate Rate to the date of exercise and the
amount of unpaid Certificateholders' Interest Index Carryover with respect
thereto.

                  (b) Insolvency of the Seller. Upon any sale of the assets of
the Trust pursuant to Section 9.02 of the Trust Agreement, the Administrator
shall instruct the Indenture Trustee to deposit the net proceeds from such sale
after all payments and reserves therefrom (including the expenses of such sale)
have been made (the "Insolvency Proceeds") in the Collection Account. On the
Distribution Date, or, if such proceeds are not so deposited on a Distribution
Date, on the first Distribution Date following the date on which the Insolvency
Proceeds are deposited in the Collection Account, the Administrator shall
instruct the Indenture Trustee to make the following 



                                      -45-
<PAGE>   50



distributions (after the application on such Distribution Date of the amount of
Available Funds and amounts on deposit in the Reserve Account pursuant to
Sections 5.05 and 5.06) from the Insolvency Proceeds and any funds remaining on
deposit in the Reserve Account (including the proceeds of any sale of
investments therein as described in the following sentence):

                  (i) to the holders of the Notes, any unpaid Noteholders'
         Interest Distribution Amount for such Distribution Date;

                  (ii) to the holders of the Notes, the outstanding principal
         balance of the Notes;

                  (iii) to the holders of the Certificates, any unpaid
         Certificateholders' Interest Distribution Amount for such Distribution
         Date;

                  (iv) to the holders of the Certificates, the Certificate
         Balance;

                  (v) to the Servicers, any unpaid Excess Servicing Fees;

                  (vi) to the holders of the Notes, any unpaid Noteholders'
         Interest Index Carryover; and

                  (vii) to the holders of the Certificates, any unpaid
         Certificateholders' Interest Index Carryover.

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

                  (c) Auction of Financed Student Loans. Any Financed Student
Loans remaining in the Trust as of the end of the Collection Period immediately
preceding the March 2009 Distribution Date will be offered for sale by the
Indenture Trustee. KeyCorp, its affiliates (other than the Seller), PHEAA, TERI
and unrelated third parties may offer bids to purchase such Financed Student
Loans on such Distribution Date; provided, however, that KeyCorp and its
affiliates may not bid more than an amount determined by KeyCorp in good faith
to be equal to the fair market value of such Financed Student Loans as of the
end of the Collection Period immediately preceding such Distribution Date. If at
least two bids are received, the Indenture Trustee will solicit and resolicit
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 the Minimum Purchase
Amount. 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 Minimum
Purchase Amount, the Indenture Trustee will not consummate such sale. In
connection with the determination of the Minimum Purchase Amount, the Indenture
Trustee may consult, and, at the direction of the Seller, shall consult, with a
financial advisor (which may be the Administrator) to determine if the fair
market value of the 



                                      -46-
<PAGE>   51



Financed Student Loans has been offered. The proceeds of any such sale will be
applied in the order of priority set forth in Section 5.04(b) of the Indenture.
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 to purchase
the Financed Student Loans on future Distribution Dates upon terms similar to
those described above.

                  (d) Notice. As described in Article IX of the Trust Agreement,
notice of any termination of the Trust shall be given by the Administrator to
the Eligible Lender Trustee and the Indenture Trustee as soon as practicable
after the Administrator has received notice thereof.

                  (e) Succession. Following the satisfaction and discharge of
the Indenture and the payment in full of the principal of and interest on the
Notes, the holders of Certificates will succeed to the rights of the holders of
Notes hereunder other than Section 5.06(b) and the Eligible Lender Trustee will
succeed to the rights of (except for the rights of the Indenture Trustee which
have accrued prior to the satisfaction and discharge of the Indenture and the
payment in full of the principal of and interest on the Notes), and assume the
obligations of, the Indenture Trustee pursuant to this Agreement and any other
Basic Documents.

                                   ARTICLE XI

                                  Miscellaneous

                  SECTION 11.01. Amendment. This Agreement may be amended by the
Seller, the Servicers, the Administrator and the Eligible Lender Trustee, with
the consent of the Indenture Trustee, but without the consent of any of the
holders of Notes or the holders of Certificates (which shall not be unreasonably
withheld), 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 holders of Notes or the holders of Certificates;
provided, however, that such action shall not, as evidenced by an Opinion of
Counsel delivered to the Eligible Lender Trustee and the Indenture Trustee,
adversely affect in any material respect the interests of any holder of Notes or
holder of Certificates; provided, further, any such amendment which affects only
one Servicer shall be deemed to be agreed to by the unaffected Servicer and such
unaffected Servicer hereby agrees to execute appropriate instruments to document
such agreement.


                                      -47-
<PAGE>   52



                  This Agreement may also be amended from time to time by the
Seller, the Servicers, the Administrator and the Eligible Lender Trustee, with
the consent of the Indenture Trustee, the consent of the holders of Notes
evidencing not less than a majority of the Outstanding Amount of the Notes, the
consent of the holders 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 holders of Notes or the holders of
Certificates; 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 Financed Student Loans or distributions
that shall be required to be made for the benefit of the holders of Notes or the
holders of Certificates or (b) reduce the aforesaid percentage of the
Outstanding Amount of the Notes and the Certificate Balance, holders of Notes or
the holders of Certificates of which are required to consent to any such
amendment, without the consent of all outstanding holders of Notes and holders
of Certificates; provided, further, any such amendment which affects only one
Servicer shall be deemed to be agreed to by the unaffected Servicer and such
unaffected Servicer hereby agrees to execute appropriate instruments to document
such agreement.

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

                  It shall not be necessary for the consent of holders of
Certificates or holders of Notes 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 this Agreement, the
Eligible Lender Trustee and the Indenture 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 and the Opinion of Counsel referred
to in Section 11.02(i)(1). The Eligible Lender Trustee and the Indenture Trustee
may, but shall not be obligated to, enter into any such amendment which affects
the Eligible Lender Trustee's or the Indenture Trustee's, as applicable, own
rights, duties or immunities under this Agreement or otherwise.

                  SECTION 11.02. Protection of Interests in Trust. (a) The
Seller shall execute and file such financing statements and cause to be executed
and filed such continuation statements, all in such manner and in such places as
may be required by law fully to preserve, maintain, and protect the interest of
the Issuer, the Eligible Lender Trustee and the Indenture Trustee in the
Financed Student Loans and in the proceeds thereof. The Seller shall deliver (or
cause to be delivered) to the Eligible Lender Trustee and the Indenture Trustee
file-stamped copies of, or filing receipts for, any document filed as provided
above, as soon as available following such filing.

                  (b) Neither the Seller nor the Servicer shall change its name,
identity or corporate structure in any manner that would, could or might make
any financing statement or 



                                      -48-
<PAGE>   53



continuation statement filed in accordance with paragraph (a) above seriously
misleading within the meaning of Section 9-402(7) of the UCC, unless it shall
have given the Eligible Lender Trustee and the Indenture Trustee at least five
days' prior written notice thereof and shall have promptly filed appropriate
amendments to all previously filed financing statements or continuation
statements.

                  (c) The Seller and the Servicer shall have an obligation to
give the Eligible Lender Trustee and the Indenture Trustee at least 60 days'
prior written notice of any relocation of its principal executive office if, as
a result of such relocation, the applicable provisions of the UCC would require
the filing of any amendment of any previously filed financing or continuation
statement or of any new financing statement and shall promptly file any such
amendment. Each Servicer shall at all times maintain each office from which it
shall service Financed Student Loans, and its principal executive office, within
the United States of America.

                  (d) The Servicer shall maintain accounts and records as to
each Financed Student Loan it services, as specified on Schedules A and B,
accurately and in sufficient detail to permit (i) the reader thereof to know at
any time the status of such Financed Student Loan, including payments and
recoveries made and payments owing (and the nature of each) and (ii)
reconciliation between payments or recoveries on (or with respect to) each
Financed Student Loan it services, as specified on Schedules A and B and the
amounts from time to time deposited in the Collection Account in respect of such
Financed Student Loan.

                  (e) The Servicer shall maintain its computer systems so that,
from and after the time of sale under this Agreement of the Financed Student
Loans it services, the Servicer's master computer records (including any backup
archives) that refer to a Financed Student Loan shall indicate clearly the
interest of the Issuer, the Eligible Lender Trustee and the Indenture Trustee in
such Financed Student Loan and that such Financed Student Loan is owned by the
Eligible Lender Trustee on behalf of the Issuer and has been pledged to the
Indenture Trustee. Indication of the Issuer's, the Eligible Lender Trustee's and
the Indenture Trustee's interest in a Financed Student Loan shall be deleted
from or modified on a Servicer's computer systems when, and only when, the
related Financed Student Loan shall have been paid in full or repurchased.

                  (f) If at any time the Seller or the Administrator shall
propose to sell, grant a security interest in, or otherwise transfer any
interest in student loans to any prospective purchaser, lender or other
transferee, the Servicer shall give to such prospective purchaser, lender or
other transferee computer tapes, records or printouts (including any restored
from backup archives) that, if they shall refer in any manner whatsoever to any
Financed Student Loan, shall indicate clearly that such Financed Student Loan
has been sold and is owned by the Eligible Lender Trustee on behalf of the
Issuer and has been pledged to the Indenture Trustee.

                  (g) Upon reasonable notice, the Servicer shall permit the
Indenture Trustee and its agents at any time during normal business hours to
inspect, audit (subject to the timing limitations imposed by paragraph 3 of the
Supplemental Sale and Servicing Agreement) and



                                      -49-
<PAGE>   54



make copies of and abstracts from such Servicer's records regarding any Financed
Student Loan it services.

                  (h) Upon request at any time the Eligible Lender Trustee or
the Indenture Trustee shall have reasonable grounds to believe that such request
would be necessary in connection with its performance of its duties under the
Basic Documents, the Servicer shall furnish to the Eligible Lender Trustee or to
the Indenture Trustee (in each case, with a copy to the Administrator), within
