          SECTION 2.1     FORM. The Notes, together with the Indenture Trustee's
certificate of authentication, shall be in substantially the forms set forth in
Exhibit A, with such appropriate insertions, omissions, substitutions and other
variations as are required or permitted by this Indenture and may have such
letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may, consistently herewith, be determined by the
officers executing the Notes, as evidenced by their execution of the Notes. Any

engraved borders), all as determined by the officers executing such Notes, as
evidenced by their execution of such Notes.

          The terms of the Notes set forth in Exhibit A are part of the terms of
this Indenture.

          Each Floating Rate Note (including the Class A-5A Notes during the
initial Reset Period) initially will be represented by interests in a global
registered note certificate deposited with The Bank of New York, as custodian
for DTC (the "DTC Custodian"), and registered in the name of a nominee for DTC.

          Each class of Reset Rate Notes denominated in U.S. Dollars (including
the Class A-5A Notes during the initial Reset Period) may be offered and sold
only in the United States of America to a QIB, and initially will be represented
by interests in a global registered note certificate (each a "U.S. Rule 144A
Global Note Certificate"), deposited on the Closing Date with the DTC Custodian,
and registered in the name of a nominee for DTC. At all times, the entire
Outstanding Amount of any Class of Reset Rate Notes then denominated in U.S.
Dollars will be allocated to the corresponding U.S. Rule 144A Global Note
Certificate. On the Closing Date, a corresponding Non-U.S. Rule 144A Global Note
Certificate (as defined below) and Regulation S Global Note Certificate (as
defined below) for such class of Reset Rate Notes will be deposited with the
Regulation S Custodian (as defined below), registered in the name of a joint
nominee for Euroclear and Clearstream, Luxembourg and each such global
registered note certificate will have an outstanding principal balance of zero
for so long as such class of Reset Rate Notes is denominated in U.S. Dollars.

          Each class of Reset Rate Notes denominated in a currency other than
U.S. Dollars (including the Class A-5B Notes during the initial Reset Period)
may be offered and sold only to QIB's or a non-U.S. Person, (as defined in
Regulation S) outside the United States of America in reliance on Rule 144A or
Regulation S, as applicable, and will be represented by interests in

                                        3
<Page>

either a Rule 144A global registered note certificate (each a "Non-U.S. Rule
144A Global Note Certificate") or a Regulation S global registered note
certificate (each a "Regulation S Global Note Certificate," and collectively
with the Non-U.S. Rule 144A Global Note Certificate, the "Non-U.S. Global Note
Certificates"). Each Non-U.S. Global Note Certificate will be registered in the
name of a joint nominee for Euroclear and Clearstream, Luxembourg, and will be
deposited on the Closing Date with The Bank of New York, acting through its
London branch, as common depositary for Euroclear and Clearstream, Luxembourg
(the "Regulation S Custodian"). At all times, there will be only one Non-U.S.
Rule 144A Global Note Certificate and one Regulation S Global Note Certificate
for each Class of Reset Rate Notes. At all times, the entire Outstanding Amount
of any class of Reset Rate Notes denominated in a currency other than U.S.
Dollars will be allocated between the corresponding Non-U.S. Rule 144A Global
Note Certificate and Regulation S Global Note Certificate for that class. On the
Closing Date, a corresponding U.S. Rule 144A Global Note Certificate will be
deposited with the DTC Custodian and will have an outstanding principal balance
of zero for so long as such Class of Reset Rate Notes is denominated in a
currency other than U.S. Dollars.

          SECTION 2.2     EXECUTION, AUTHENTICATION AND DELIVERY. The Notes
shall be executed on behalf of the Issuer by any of its Authorized Officers. The
signature of any such Authorized Officer on the Notes may be manual or
facsimile.

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

          The Indenture Trustee shall upon Issuer Order authenticate and deliver
Notes for original issue in an aggregate principal amount of $2,532,844,000,
using an exchange rate of $1.1330 = EURO 1.00 with respect to the aggregate
principal amount of EURO 750,000,000 of the Class A-5B Notes). The aggregate
principal amount of Notes outstanding at any time may not exceed such amount
except as provided in Section 2.5. On each Spread Determination Date, upon
receipt of an Issuer Order, the Indenture Trustee shall deliver a revised
Schedule A for the related class of Reset Rate Notes to the Custodians.

          Each Note shall be dated the date of its authentication. The Floating
Rate Class A Notes shall be issuable as registered Class A Notes in multiples of
$1,000. During the related initial Reset Period, the Class A-5A Notes shall be
issuable as registered in minimum denominations of $250,000 and additional
increments of $1, and the Class A-5B Notes shall be issuable as registered in
minimum denominations of EURO 250,000 and additional increments of EURO 1. The
Class B Notes shall be issuable as registered Class B Notes in minimum

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

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

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

          SECTION 2.4     REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.
The Issuer shall cause to be kept a register (the "Note Register") in which,
subject to such reasonable regulations as it may prescribe, the Issuer shall
provide for the registration of Notes and the registration of transfers of
Notes. The Indenture Trustee shall be "Note Registrar" for the purpose of
registering Notes and transfers of Notes as herein provided. Upon any
resignation of any Note Registrar, the Issuer shall promptly appoint a successor
or, if it elects not to make such an appointment, assume the duties of Note
Registrar.

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

          Upon surrender for registration of transfer of any Note at the office
or agency of the Issuer to be maintained as provided in Section 3.2 or, with
respect to the Reset Rate Notes, to the Note Registrar or any transfer agent, as
applicable if the requirements of Section 8-401(1) of the UCC are met, the
Issuer shall execute, and the Indenture Trustee shall authenticate and the
Noteholder shall obtain from the Indenture Trustee, in the name of the
designated transferee or

                                        5
<Page>

transferees, one or more new Notes in any authorized denominations and a like
aggregate principal amount.

          On each Reset Date on which either the All Hold Rate is not applicable
or fewer than 100% of a class of Reset Rate Noteholders permissibly elect to
hold their Reset Rate Notes, the Indenture Trustee shall allocate the entire
Outstanding Amount of such class of Reset Rate Notes to either the U.S. Rule
144A Global Note Certificate or the Non-U.S. Global Note Certificates, as
appropriate. Any transfer of Reset Rate Notes (other than on a Reset Date)
between the related U.S. Rule 144A Global Note Certificate and the related
Non-U.S. Global Note Certificates is not permitted and any attempt or
inadvertent transfer shall be null and void and of no effect

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

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

          Every Note presented or surrendered for registration of transfer or
exchange shall be duly endorsed by, or be accompanied by a written instrument of
transfer in form satisfactory to the Indenture Trustee duly executed by the
Noteholder thereof or such Noteholder's attorney duly authorized in writing,
with such signature guaranteed by an "eligible guarantor institution" meeting
the requirements of the Note Registrar, which requirements include membership or
participation in Securities Transfer Agent's Medallion Program ("STAMP") or such
other "signature guarantee program" as may be determined by the Note Registrar
in addition to, or in substitution for, STAMP, all in accordance with the
Exchange Act.

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

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

          SECTION 2.5     MUTILATED, DESTROYED, LOST OR STOLEN NOTES. If (i) any
mutilated Note is surrendered to the Indenture Trustee, or the Indenture Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any
Note, and (ii) there is delivered to the Issuer and the Indenture Trustee such
security or indemnity as may be required by each of them to hold

                                        6
<Page>

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 Noteholder thereof of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other reasonable expenses (including the fees and expenses of
the Indenture Trustee) connected therewith.

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

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

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

          SECTION 2.7     PAYMENT OF PRINCIPAL AND INTEREST; NOTE INTEREST
SHORTFALL. (a) The Floating Rate Notes shall accrue interest as provided in the
forms of Notes set forth in Exhibit A and the Reset Rate Notes shall accrue
interest as provided in Appendix A-2, and such interest shall be payable on each
applicable Distribution Date as specified therein, subject to Section 3.1. Any
installment of interest or principal, if any, payable on any Note which is

                                        7
<Page>

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 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 Notes registered on the
Record Date in the name of the nominee of the applicable Clearing Agency
(initially, such nominee to be Cede & Co. for the Floating Rate Notes and the
Class A-5A Notes and The Bank of New York (Nominees) Limited for the Class A-5B
Notes), payment shall be made by wire transfer in immediately available funds to
the account designated by such nominee and except for the final installment of
principal payable with respect to such Note on a Distribution Date or on the
Note Final Maturity Date for such Note which shall be payable as provided below.
The funds represented by any such checks returned undelivered shall be held in
accordance with Section 3.3.

     (b)  The principal of each class of Floating Rate Notes shall be payable in
installments on each applicable Distribution Date as provided in the forms of
Note set forth in Exhibit A and, the principal of each class of Reset Rate Notes
shall be payable on each applicable Distribution Date as set forth in Appendix
A-2. Notwithstanding the foregoing, the entire unpaid principal amount of each
class of the Notes shall be due and payable, if not previously paid, on the Note
Final Maturity Date for such class of Notes and on the date on which an Event of
Default shall have occurred and be continuing if the Indenture Trustee or the
Noteholders of the Notes representing not less than a majority of the
Outstanding Amount of the Notes have declared the Notes to be immediately due
and payable in the manner provided in Section 5.2. All principal payments on the
Notes shall be made pro rata to the specific class of Noteholders entitled
thereto. The Indenture Trustee shall notify the Person in whose name a Note is
registered at the close of business on the Record Date preceding the
Distribution Date on which the Issuer expects that the final installment of
principal of and interest on such Note will be paid. Such notice shall be mailed
or transmitted by facsimile prior to such final Distribution Date and shall
specify that such final installment will be payable only upon presentation and
surrender of such Note and shall specify the place where such Note may be
presented and surrendered for payment of such installment. Notices in connection
with redemptions of Notes shall be mailed to Noteholders as provided in Section
10.2.

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

          SECTION 2.8     CANCELLATION. All Notes surrendered for payment,
registration of transfer, exchange or redemption shall, if surrendered to any
Person other than the Indenture Trustee, be delivered to the Indenture Trustee
and shall be promptly cancelled by the Indenture Trustee. The Issuer may at any
time deliver to the Indenture Trustee for cancellation any Notes previously
authenticated and delivered hereunder which the Issuer may have acquired in any
manner whatsoever and all Notes so delivered shall be promptly cancelled by the
Indenture Trustee. No Notes shall be authenticated in lieu of or in exchange for
any Notes cancelled as provided in this Section, except as expressly permitted
by this Indenture. All canceled Notes may be held or disposed of by the
Indenture Trustee in accordance with its standard retention or disposal policy
as in effect at the time, unless the Issuer shall direct by an Issuer Order that
they

                                        8
<Page>

be returned to it and so long as such Issuer Order is timely and the Notes have
not been previously disposed of by the Indenture Trustee.

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

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

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

          (ii)    the Note Registrar and the Indenture Trustee, and their
respective directors, officers, employees and agents, may deal with the
applicable 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 applicable Clearing Agency and shall be limited to those established by law
and agreements between such Note Owners and the applicable Clearing Agency
and/or the applicable Clearing Agency Participants pursuant to the Note
Depository Agreements; and unless and until Definitive Notes are issued pursuant
to Section 2.12, the applicable initial Clearing Agency will make book-entry
transfers among the applicable Clearing Agency Participants and receive and
transmit payments of principal of and interest and other amounts on the Notes to
such applicable Clearing Agency Participants;

          (v)     whenever this Indenture requires or permits actions to be
taken based upon instructions or directions of Noteholders of Notes evidencing a
specified percentage of the Outstanding Amount of the Notes, the applicable
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
applicable 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; and

          (vi)    upon acquisition or transfer of a beneficial interest in any
Book-Entry Note by, for or with the assets of, an employee benefit plan or other
retirement arrangement

                                        9
<Page>

subject to Section 406 of ERISA or Section 4975 of the Code, such Note Owner
shall be deemed to have represented that such acquisition or purchase will not
constitute or otherwise result in a non-exempt prohibited transaction in
violation of Section 406 of ERISA or Section 4975 of the Code which is not
covered by a class or other applicable exemption. Any transfer found to have
been made in violation of such deemed representation shall be null and void and
of no effect.

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

          SECTION 2.12    DEFINITIVE NOTES. If (i) the Administrator advises the
Indenture Trustee in writing that a Clearing Agency (a) is closed for business
for a continuous period of 14 days (other than by reason of holiday, statutory
or otherwise), (b) announces an intention to cease business permanently (or does
so and no alternative clearing system acceptable to the Indenture Trustee is
then available), or (c) at any time, is unwilling or unable to continue as, or
ceases to be, a clearing agency registered under all applicable laws, and a
successor clearing agency which is registered as a clearing agency under all
applicable laws is not appointed by the Administrator within 90 days of such
event, (ii) the Administrator at its option advises the Indenture Trustee in
writing that it elects to terminate the book-entry system through that 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 applicable
Notes advise the applicable Clearing Agency (which shall then notify the
Indenture Trustee) in writing that the continuation of a book-entry system
through such Clearing Agency is no longer in the best interests of such Note
Owners, then the Indenture Trustee shall cause such Clearing Agency to notify
all Note Owners cleared, through such 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 a 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
such Clearing Agency, which shall include, without limitation, the identity and
payment instructions for all Noteholders of the applicable Notes. None of the
Issuer, the Note Registrar or the Indenture Trustee shall be liable for any
delay in delivery of such instructions and may conclusively rely on, and shall
be protected in relying on, such instructions. Upon the issuance of Definitive
Notes, the Indenture Trustee shall recognize the holders of the Definitive Notes
as Noteholders.

          Upon acquisition or transfer a Definitive Note by, for or with the
assets of, an employee benefit plan or other retirement arrangement subject to
Section 406 of ERISA or Section 4975 of the Code, such Note Owner shall be
deemed to have represented that such acquisition or purchase will not constitute
or otherwise result in a non-exempt prohibited transaction in violation of
Section 406 of ERISA or Section 4975 of the Code which is not covered by a class
or other applicable exemption. Any transfer found to have been made in violation
of such representation shall be null and void and of no effect.

          SECTION 2.13    TRANSFER RESTRICTIONS. Each Noteholder and Note
Owner of a class of Reset Rate Notes shall be subject to the restrictions on
transfer thereof set forth in Appendix A-3 to this Indenture.

                                   ARTICLE III

                                    COVENANTS

          SECTION 3.1     PAYMENT TO NOTEHOLDERS AND EACH SWAP COUNTERPARTY.
The Issuer shall duly and punctually pay the principal and interest, if any,
with respect to the Notes in accordance with the terms of the Notes and this
Indenture and shall duly and punctually pay amounts, if any, owing to each Swap
Counterparty in accordance with the terms of this Indenture and the related Swap
Agreement. Without limiting the foregoing, the Issuer shall cause to be
distributed to Noteholders and each Swap Counterparty in accordance with the
Administration Agreement that portion of the amounts on deposit in the Trust
Accounts (other than Investment Earnings on any Accumulation Account, any Euro
Account, any Other Currency Account or the Reserve Account) on a Distribution
Date (other than any Eligible Investments deposited therein that will mature on
the Business Day preceding a subsequent Distribution Date), or with respect to
any Swap Counterparty amounts on deposit in the relevant Trust Accounts (other
than Investment Earnings on any Accumulation Account, any Euro Account, any
Other Currency Account or the Reserve Account) on the date such payment is due
under the related Swap Agreement, which the Noteholders and any Swap
Counterparty are entitled to receive pursuant to Sections 2.7 and 2.8 of the
Administration Agreement. Amounts properly withheld under the Code by any Person
from a payment to any Noteholder of interest and/or principal shall be
considered as having been paid by the Issuer to such Noteholder for all purposes
of this Indenture.

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

          SECTION 3.3     MONEY FOR PAYMENTS TO BE HELD IN TRUST. As provided in
Section 8.2(a) and (b), all payments of amounts due and payable with respect to
any Notes or any Swap Agreement that are to be made from amounts distributed
from the Collection Account or any other Trust Account pursuant to Sections 2.7
and 2.8 of the Administration Agreement 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 or any Swap Agreement shall be
paid over to the Issuer except as provided in this Section.

                                       11
<Page>

          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 or any Swap Agreement, such
sum to be held in trust for the benefit of the Persons entitled thereto and
(unless the Paying Agent is the Indenture Trustee) shall promptly notify the
Indenture Trustee of its action or failure so to act.

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

          (i)     hold all sums held by it for the payment of amounts due with
respect to the Notes or any Swap Agreement 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 or any Swap
Agreement;

          (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 or any
Swap Agreement if at any time it ceases to meet the standards required to be met
by a Paying Agent at the time of its appointment; and

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

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

          Subject to applicable laws with respect to escheat of funds, any money
held by the Indenture Trustee or any Paying Agent in trust for the payment of
any amount due with respect to any Note and remaining unclaimed for two years
after such amount has become due and payable shall be discharged from such trust
and be paid to the Issuer on Issuer Request or if the Issuer has been terminated
to the Depositor upon its written request; and the Noteholder thereof shall
thereafter, as an unsecured general creditor, look only to the Issuer for
payment thereof (but

                                       12
<Page>

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 and Luxembourg, notice that
such money remains unclaimed and that, after a date specified therein, which
shall not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Issuer. The Indenture
Trustee shall also adopt and employ, at the expense of the Issuer, any other
reasonable means of notification of such repayment (including mailing notice of
such repayment to Noteholders whose Notes have been called but have not been
surrendered for redemption or whose right to or interest in moneys due and
payable but not claimed is determinable from the records of the Indenture
Trustee or of any Paying Agent, at the last address of record for each such
Noteholder).

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

          SECTION 3.5     PROTECTION OF INDENTURE TRUST ESTATE. The Issuer will
from time to time execute and deliver all such supplements and amendments hereto
and all such financing statements, continuation statements, will take such other
action necessary or advisable to:

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

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

          (iii)   enforce any of the Collateral; or

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

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

          SECTION 3.6     OPINIONS AS TO INDENTURE TRUST ESTATE. (a) On the
Closing Date, the Issuer shall furnish to the Indenture Trustee an Opinion of
Counsel either stating that, in the opinion of such counsel, such action has
been taken with respect to the recording and filing of this

                                       13
<Page>

Indenture as is necessary to perfect and make effective the lien and security
interest of this Indenture and reciting the details of such action, or stating
that, in the opinion of such counsel, no such action is necessary to make such
lien and security interest effective.

     (b)  On or before December 31 in each calendar year, beginning in 2003, the
Issuer shall furnish to the Indenture Trustee an Opinion of Counsel either
stating that, in the opinion of such counsel, such action has been taken with
respect to the recording, filing, re-recording and refiling of this Indenture
and any indentures supplemental hereto as is necessary to maintain the lien and
security interest created by this Indenture and relating the details of such
action or stating that in the opinion of such counsel no such action is
necessary to maintain such lien and security interest. Such Opinion of Counsel
shall also describe the recording, filing, recording and refiling of this
Indenture and any indentures supplemental hereto that will, in the opinion of
such counsel, be required to maintain the lien and security interest of this
Indenture until December 31 in the following calendar year.

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

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

     (c)  The Issuer shall punctually perform and observe all of its obligations
and agreements contained in this Indenture, the other Basic Documents and the
instruments and agreements included in the Indenture Trust Estate, including
filing or causing to be filed all UCC financing statements and continuation
statements prepared by the Issuer and required to be filed by the terms of this
Indenture and the Administration Agreement in accordance with and within the
time periods provided for herein and therein. Except as otherwise expressly
provided therein, the Issuer shall not waive, amend, modify, supplement or
terminate any Basic Document or any provision thereof without the consent of the
Indenture Trustee or the Noteholders of at least a majority of the Outstanding
Amount of the Notes. The Issuer shall give written notice to each Rating Agency
of any such waiver, amendment, modification, supplement or termination.

     (d)  If a Responsible Officer of the Issuer shall have knowledge of the
occurrence of a Servicer Default or an Administrator Default under the Servicing
Agreement or the Administration Agreement, respectively, the Issuer shall
promptly notify the Indenture Trustee and the Rating Agencies thereof, and shall
specify in such notice the action, if any, the Issuer is taking with respect to
such default. If a Servicer Default shall arise from the failure of the

                                       14
<Page>

Servicer to perform any of its duties or obligations under the Servicing
Agreement, or an Administrator Default shall arise from the failure of the
Administrator to perform any of its duties or obligations under the
Administration Agreement, as the case may be, with respect to the Trust Student
Loans, the Issuer shall take all reasonable steps available to it to enforce its
rights under the Basic Documents in respect of such failure.

     (e)  As promptly as possible after the giving of notice of termination to
the Servicer of the Servicer's rights and powers, pursuant to Section 5.1 of the
Servicing Agreement, or to the Administrator of the Administrator's rights and
powers, pursuant to Section 5.1 of the Administration Agreement, the Issuer
shall appoint a successor servicer (the "Successor Servicer") or a successor
administrator (the "Successor Administrator"), respectively, and such Successor
Servicer or Successor Administrator, as the case may be, shall accept its
appointment by a written assumption in a form acceptable to the Indenture
Trustee. In the event that a Successor Servicer or Successor Administrator has
not been appointed and accepted its appointment at the time when the Servicer or
Administrator, as the case may be, ceases to act as Servicer or Administrator,
respectively, the Indenture Trustee without further action shall automatically
be appointed the Successor Servicer or Successor Administrator, as the case may
be. The Indenture Trustee may resign as the Successor Servicer or the Successor
Administrator by giving written notice of resignation to the Issuer and in such
event will be released from such duties and obligations, such release not to be
effective until the date a new servicer or a new administrator enters into an
agreement with the Issuer as provided below; PROVIDED, HOWEVER, that nothing
herein shall require or permit the Indenture Trustee to act as Servicer, or
otherwise service the Trust Student Loans, in violation of the Higher Education
Act. Upon delivery of any such notice to the Issuer, the Issuer shall obtain a
new servicer as the Successor Servicer under the Servicing Agreement or a new
administrator as the Successor Administrator under the Administration Agreement,
as the case may be. Any Successor Servicer or Successor Administrator, other
than the Indenture Trustee, shall (i) be an established institution (A) that
satisfies any requirements of the Higher Education Act applicable to servicers
and (B) whose regular business includes the servicing or administration of
student loans and (ii) enter into a servicing agreement or an administration
agreement, respectively, with the Issuer having substantially the same
provisions as the provisions of the Servicing Agreement and the Administration
Agreement, as applicable. If within 30 days after the delivery of the notice
referred to above, the Issuer shall not have obtained such a new servicer or new
administrator, as the case may be, the Indenture Trustee may appoint, or may
petition a court of competent jurisdiction to appoint, a Successor Servicer or
Successor Administrator; PROVIDED, HOWEVER, that such right to appoint or to
petition for the appointment of any such successor shall in no event relieve the
Indenture Trustee from any obligations otherwise imposed on it under the Basic
Documents until such successor has in fact assumed such appointment. In
connection with any such appointment, the Indenture Trustee may make such
arrangements for the compensation of such successor as it and such successor
shall agree, subject to the limitations set forth below and in the Servicing
Agreement or Administration Agreement, as applicable, and in accordance with
Section 5.2 of the Servicing Agreement and Section 5.2 of the Administration
Agreement, the Issuer shall enter into an agreement with such successor for the
servicing or administration of the Trust Student Loans (such agreement to be in
form and substance satisfactory to the Indenture Trustee). If the Indenture
Trustee shall succeed as provided herein to the Servicer's duties as Servicer
with respect to the Trust Student Loans, or the Administrator's duties with
respect to the Issuer and the Trust Student Loans, as the case may be, it shall
do so in its individual capacity

                                       15
<Page>

and not in its capacity as Indenture Trustee and, accordingly, the provisions of
Article VI hereof shall be inapplicable to the Indenture Trustee in its duties
as the successor to the Servicer or the Administrator, as the case may be, and
the servicing or administration of the Trust Student Loans. In case the
Indenture Trustee shall become successor to the Servicer or the Administrator,
the Indenture Trustee shall be entitled to appoint as Servicer or as
Administrator, as the case may be, any one of its Affiliates, provided that such
appointment shall not affect or alter in any way the liability of the Indenture
Trustee as Successor Servicer or Successor Administrator, respectively, in
accordance with the terms hereof.

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

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

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

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

          (ii)    claim any credit on, or make any deduction from the principal
or interest payable in respect of, the Notes (other than amounts properly
withheld from such

                                       16
<Page>

payments under the Code or applicable state law) or assert any claim against any
present or former Noteholder by reason of the payment of the taxes levied or
assessed upon any part of the Indenture Trust Estate;

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

          (iv)    enter into any amendment to the Interest Rate Cap Agreement or
any Swap Agreement to cure any ambiguity in, or to correct or supplement any
provision of the Interest Rate Cap Agreement or any Cross-Currency Swap
Agreement, unless the Issuer has determined, and the Indenture Trustee has
agreed in writing at the written direction of the Issuer, that the amendment
will not materially adversely affect the interests of the Noteholders and
provided that the Indenture Trustee has provided reasonable notice to the Rating
Agencies of such amendment and each Rating Agency has provided written
confirmation that the then-current rating of the Notes will not be lowered or
withdrawn. No Swap Agreement entered into by the Issuer may be amended or
modified unless the Rating Agency Condition is satisfied.

          SECTION 3.9     ANNUAL STATEMENT AS TO COMPLIANCE. The Issuer will
deliver to the Indenture Trustee and each Rating Agency, within 120 days after
the end of each fiscal year of the Issuer (commencing with the fiscal year
ending December 31, 2003), an Officers' Certificate of the Issuer stating that:

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

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

          SECTION 3.10    ISSUER MAY CONSOLIDATE, ETC., ONLY ON CERTAIN TERMS

     (a)  The Issuer shall not consolidate or merge with or into any other

Trustee under the provisions of this Indenture with respect to such Notes shall,
upon demand of the Issuer, be paid to the Indenture Trustee to be held and
applied according to Section 3.3 and thereupon such Paying Agent shall be
released from all further liability with respect to such moneys.

          SECTION 4.4     AUCTION OF TRUST STUDENT LOANS. Any Trust Student

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

                                    REMEDIES

          SECTION 5.1     EVENTS OF DEFAULT. "Event of Default," wherever used

five days; or

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

          (iii)   default in the observance or performance of any covenant or

breach having a material adverse effect on the holders of the Notes, and such
default or breach shall continue or not be cured, or the circumstance or
condition in respect of which such misrepresentation or warranty was incorrect
shall not have been eliminated or otherwise cured, for a period of 30 days after
there shall have been given, by registered or certified mail, to the Issuer by
the Indenture Trustee or to the Issuer and the Indenture Trustee by the

notice specifying such default or incorrect representation or warranty and
requiring it to be remedied and stating that such notice is a notice of Default
hereunder; or

          (iv)    the filing of a decree or order for relief by a court having

or similar official of the Issuer or for any substantial part of the Indenture
Trust Estate, or ordering the winding-up or liquidation of the Issuer's affairs,

          SECTION 5.2     ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT. If
an Event of Default should occur and be continuing, then and in every such case
the Indenture Trustee or the Noteholders representing not less than a majority
of the Outstanding Amount of the Notes may declare all the Notes to be
immediately due and payable, by a notice in writing to the Issuer (and to the
Indenture Trustee if given by Noteholders), and upon any such declaration the
unpaid principal amount of such Notes, together with accrued and unpaid interest
thereon through the date of acceleration, shall become immediately due and
payable, subject, however, to Section 5.4 of this Indenture.

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

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

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

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

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

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

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

     (a)  In case the Issuer shall fail forthwith to pay such amounts upon such
demand, the Indenture Trustee, in its own name and as trustee of an express
trust, may institute a Proceeding

                                       24
<Page>

for the collection of the sums so due and unpaid, and may prosecute such
Proceeding to judgment or final decree, and may enforce the same against the
Issuer or other obligor upon such Notes and collect in the manner provided by
law out of the property of the Issuer or other obligor upon such Notes, wherever
situated, the moneys adjudged or decreed to be payable.

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

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

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

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

          (iii)   to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute all amounts received with
respect to the claims of the Noteholders, any Swap Counterparty and 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, any Swap Counterparty or the Noteholders allowed in any judicial
proceedings relative to the Issuer, its creditors and its property;

                                       25
<Page>

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

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

     (e)  All rights of action and of asserting claims under this Indenture, or
under any of the Notes, may be enforced by the Indenture Trustee without the
possession of any of the Notes or the production thereof in any trial or other
Proceedings relative thereto, and any such action or Proceedings instituted by
the Indenture Trustee shall be brought in its own name as trustee of an express
trust, and any recovery of judgment, subject to the payment of the expenses,
disbursements and compensation of the Indenture Trustee, each predecessor
Indenture Trustee and their respective agents and attorneys, shall be for the
ratable benefit of the Noteholders, and after the Notes have been paid in full,
and subject to the provisions of Section 11.19, any Swap Counterparty.

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

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

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

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

                                       26
<Page>

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

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

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

PROVIDED, HOWEVER, that the Indenture Trustee may not sell or otherwise
liquidate the Indenture Trust Estate following an Event of Default, other than
an Event of Default described in Section 5.1(i) or (ii) with respect to the
Class A Notes, unless (A) the Noteholders of 100% of the Outstanding Amount of
the Class A Notes consent thereto, (B) the proceeds of such sale or liquidation
distributable to the Class A Noteholders are sufficient to discharge in full all
amounts then due and unpaid upon such Class A Notes for principal and interest
or (C) the Indenture Trustee determines that the Indenture Trust Estate will not
continue to provide sufficient funds for the payment of principal of and
interest on the Class A Notes as would have become due if the Class A Notes had
not been declared due and payable, and the Indenture Trustee obtains the consent
of Noteholders of 66 2/3% of the Outstanding Amount of the Class A Notes;
PROVIDED, FURTHER, that the Indenture Trustee may not sell or otherwise
liquidate the Indenture Trust Estate following an Event of Default, other than
an Event of Default described in Section 5.1(i) or (ii) with respect to the
Class A Notes, unless (D) the proceeds of such sale or liquidation distributable
to the Class B Noteholders plus the proceeds of the sale or liquidation of the
Trust Estate distributable to the Class B Noteholders are sufficient to pay to
the Class B Noteholders the Outstanding Amount of the Class B Notes plus accrued
and unpaid interest thereon or (E) after receipt of notice from the Eligible
Lender Trustee that the proceeds of such sale or liquidation distributable to
the Class B Noteholders plus the proceeds of the sale or liquidation of the
Trust Estate distributable to the Class B Noteholders would not be sufficient to
pay to the Class B Noteholders the outstanding principal plus accrued and unpaid
interest thereon, the Class B Noteholders of at least a majority of the
Outstanding Amount of the Class B Notes consent thereto. In determining such
sufficiency or insufficiency with respect to clauses (B), (C), (D) and (E), the
Indenture Trustee may, but need not, obtain and rely upon an opinion of an
Independent investment banking or accounting firm of national reputation as to
the feasibility of such proposed action and as to the sufficiency of the
Indenture Trust Estate and/or Trust Estate, as applicable, for such purpose.

     (b)  Notwithstanding the provisions of Section 8.2, following the
occurrence and during the continuation of an Event of Default specified in
Section 5.1(i), 5.1(ii), 5.1(iv) or 5.1(v) which has resulted in an acceleration
of the Notes, if the Indenture Trustee collects any money or property, it shall
pay out the money or property (and other amounts including amounts, if any, held
on deposit in each of the Trust Accounts) held as Collateral for the benefit of
the Noteholders, net of liquidation costs associated with the sale of the assets
of the Trust, in the following order:

                                       27

               amounts due and unpaid on the Class A Notes for interest at the
               applicable Note Rate, ratably, without preference or priority of
               any kind, according to the amounts due and payable on the Class A
               Notes for such interest; and

               B:   if one or more Swap Agreements are then in effect, to each

               C:   if one or more Swap Agreements are then in effect, to the
               Swap Counterparties, the amount of any Swap Termination Payments
               due to the related Swap Counterparty due to a Swap Termination
               Event (as defined in the related Swap Agreement) resulting from a

               the Issuer;

          SIXTH:  A: So long as any class of Reset Rate Notes is denominated in
a currency other than U.S. Dollars, pro rata (1) to the Class A Noteholders

a currency other than U.S. Dollars), ratably, an amount sufficient to reduce the
respective principal balance of the Class A Notes to zero and (2) to the Swap
Counterparty an amount sufficient to reduce the U.S. Dollar Equivalent Principal

          B: if all classes of Reset Rate Notes are then denominated in U.S.
Dollars, pro rata (1) to the Class A Noteholders, ratably, an amount sufficient

          SEVENTH:  to the  Class  B  Noteholders  for  amounts  due and  unpaid

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

          TENTH:    to any Swap  Counterparties,  pro rata, the amount of any

deposit in the Remarketing Fee Account;

          TWELFTH:  sequentially, first to the Remarketing Agents, and second to
the Administrator for any advances made on behalf of the Issuer, in each case,
for payment of certain costs and expenses as set forth in Section 3 of the
Remarketing Agreement in connection with the remarketing of a class of Reset
Rate Notes not previously reimbursed by the Issuer;

          In the event that the related Swap Agreement has terminated, all
payments by the Trust to the Noteholders of a class of Reset Rate Notes then not
denominated in U.S. Dollars will be made in the applicable currency utilizing
the exchange rate set forth in the related Swap Agreement prior to its
termination.

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

          SECTION 5.5     OPTIONAL PRESERVATION OF THE TRUST STUDENT LOANS. If
the Notes have been declared to be due and payable under Section 5.2 following
an Event of Default and such declaration and its consequences have not been
rescinded and annulled, the Indenture Trustee may, but need not, elect to
maintain possession of the Indenture Trust Estate. It is the desire of the
parties hereto and the Noteholders that there be at all times sufficient funds
for the payment of principal of and interest on the Notes, and the Indenture
Trustee shall take such desire into account when determining whether or not to
maintain possession of the Indenture Trust Estate. In determining whether to
maintain possession of the Indenture Trust Estate, the

                                       29
<Page>

Indenture Trustee may, but need not, obtain and rely upon an opinion of an
Independent investment banking or accounting firm of national reputation as to
the feasibility of such proposed action and as to the sufficiency of the
Indenture Trust Estate for such purpose.

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

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

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

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

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

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

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

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

          SECTION 5.7     UNCONDITIONAL RIGHTS OF NOTEHOLDERS TO RECEIVE
PRINCIPAL AND INTEREST. Notwithstanding any other provisions in this Indenture,
any Noteholder shall have the right, which is absolute and unconditional, to
receive payment of the principal of and interest on such Note on or after the
respective due dates thereof expressed in such Note or in this Indenture (or, in
the case of redemption, on or after the Redemption Date) and to institute suit
for the enforcement of any such payment, and such right shall not be impaired
without the consent of such Noteholder.

          SECTION 5.8     RESTORATION OF RIGHTS AND REMEDIES. If the Indenture
Trustee or any Noteholder has instituted any Proceeding to enforce any right or
remedy under this Indenture

                                       30
<Page>

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

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

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

          SECTION 5.11    CONTROL BY NOTEHOLDERS. The Noteholders of a majority
of the Outstanding Amount of the Notes shall have the right to direct the time,
method and place of conducting any Proceeding for any remedy available to the
Indenture Trustee with respect to the Notes or exercising any trust or power
conferred on the Indenture Trustee; provided that

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

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

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

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

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

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

          Upon any such waiver, such Default shall cease to exist and be deemed
to have been cured and not to have occurred for every purpose of this Indenture;
but no such waiver shall extend to any subsequent or other Default or impair any
right consequent thereto.

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

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

          SECTION 5.15    ACTION ON NOTES. The Indenture Trustee's right to seek
and recover judgment on the Notes or under this Indenture shall not be affected
by the seeking, obtaining or application of any other relief under or with
respect to this Indenture. Neither the lien of this Indenture nor any rights or
remedies of the Indenture Trustee or the Noteholders shall be impaired by the
recovery of any judgment by the Indenture Trustee against the Issuer or by the
levy of any execution under such judgment upon any portion of the Indenture
Trust Estate or upon any of the assets of the Issuer. Any money or property
collected by the Indenture Trustee shall be applied in accordance with Section
5.4(b).

          SECTION 5.16    PERFORMANCE AND ENFORCEMENT OF CERTAIN OBLIGATIONS.

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

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

                                   ARTICLE VI

                              THE INDENTURE TRUSTEE

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

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

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

          (ii)    in the absence of bad faith on its part, the Indenture Trustee
may conclusively rely, as to the truth of the statements and the correctness of
the opinions expressed

                                       33
<Page>

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

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

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

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

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

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

          SECTION 6.2     RIGHTS OF INDENTURE TRUSTEE. (a) The Indenture Trustee
may rely on any document believed by it to be genuine and to have been signed or

                                       34
<Page>

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

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

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

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

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

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

          SECTION 6.5     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 notice of the Default to each Noteholder and
any Swap Counterparty within 90 days and to each Rating Agency as soon as
practicable within 30 days after it occurs. Except in the case of a Default in
payment of principal of or interest on any Note (including payments pursuant to
the mandatory redemption provisions of such Note), the Indenture Trustee may
withhold the notice if and so long as a committee of its Responsible Officers in
good faith determines that withholding the notice is in the interests of
Noteholders and any Swap Counterparty. Except as provided in the first sentence
of this Section 6.5, in no event shall the Indenture Trustee be deemed to have
knowledge of a Default or an Event of Default.

                                       35
<Page>

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

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

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

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

                                       36
<Page>

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

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

          (ii)    an Insolvency Event occurs with respect to the Indenture
Trustee;

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

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

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

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

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

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

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

          SECTION 6.9     SUCCESSOR INDENTURE TRUSTEE BY MERGER. If the
Indenture Trustee consolidates with, merges or converts into, or transfers all
or substantially all of 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.

                                       37
<Page>

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

          SECTION 6.10    APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE.

     (a)  Notwithstanding any other provisions of this Indenture, at any time,
for the purpose of meeting any legal requirement of any jurisdiction in which
any part of the Indenture Trust Estate may at the time be located, the Indenture
Trustee shall have the power and may execute and deliver all instruments to
appoint one or more Persons to act as a co-trustee or co-trustees, or separate
trustee or separate trustees, of all or any part of the Indenture Trust Estate,
and to vest in such Person or Persons, in such capacity and for the benefit of
the Noteholders, such title to the Indenture Trust Estate, or any part hereof,
and, subject to the other provisions of this Section, such powers, duties,
obligations, rights and trusts as the Indenture Trustee may consider necessary
or desirable. No such appointment shall relieve the Indenture Trustee of its
obligations hereunder. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
6.11 and no notice to Noteholders of the appointment of any co-trustee or
separate trustee shall be required under Section 6.8 hereof.

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

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

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

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

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

                                       38
<Page>

if given to each of them. Every instrument appointing any separate trustee or
co-trustee shall refer to this Indenture and the conditions of this Article VI.
Each separate trustee and co-trustee, upon its acceptance of the trusts
conferred, shall be vested with the estates or property specified in its
instrument of appointment, either jointly with the Indenture Trustee or
separately, as may be provided therein, subject to all the provisions of this
Indenture, specifically including every provision of this Indenture relating to
the conduct of, affecting the liability of, or affording protection to, the
Indenture Trustee. Every such instrument shall be filed with the Indenture
Trustee.

     (d)  Any separate trustee or co-trustee may at any time constitute the
Indenture Trustee, its agent or attorney-in-fact with full power and authority,
to the 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 of
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
requirements of an "eligible lender" under 20 USC Section 1085(d) and the
requirements of Rule 3a-7(4)(i) of the General Rules and Regulations under the
Investment Company Act of 1940, as amended. The Indenture Trustee shall have a
combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition and it shall have a long-term senior
unsecured debt rating of not less than investment grade by each of the Rating
Agencies. The Indenture Trustee shall comply with TIA Section 310(b), including
the optional provision permitted by the second sentence of TIA Section
310(b)(9); PROVIDED, HOWEVER, that there shall be excluded from the operation of
TIA Section 310(b)(1) any indenture or indentures under which other securities
of the Issuer are outstanding if the requirements for such exclusion set forth
in TIA Section 310(b)(1) are met.

          SECTION 6.12    PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE 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.

Record Date and (ii) three months after the last Record Date, a list, in such
form as the Indenture Trustee may reasonably require, of the names and addresses
of the Noteholders as of such Record Date, (b) at such other times as the
Indenture Trustee may request in writing, within 30 days after receipt by the
Issuer of any such request, a list of similar form and content as of a date not
more than 10 days prior to the time such list is furnished; PROVIDED, HOWEVER,
that so long as the Indenture Trustee is the Note Registrar, no such list shall
be required to be furnished.

<Page>

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

                      ACCOUNTS, DISBURSEMENTS AND RELEASES

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

          SECTION 8.2     TRUST ACCOUNTS. (a) On or prior to the Closing Date,
the Issuer shall cause the Administrator to establish and maintain, in the name
of the Indenture Trustee, for the benefit of the Noteholders and any Swap

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

of moneys deposited in the Trust Accounts (except for the Capitalized Interest
Account, if any) 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. All income or other gain from investments of moneys deposited in
the Capitalized Interest Account, if any, shall be deposited by the Indenture
Trustee in the Capitalized Interest Account, and any loss resulting from such
investments shall be charged to the Capitalized Interest Account. The Issuer

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

                                       41

investment or sale, if requested by the Indenture Trustee, the Issuer shall
deliver to the Indenture Trustee an Opinion of Counsel, acceptable to the
Indenture Trustee, to such effect.

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

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

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.

been paid, subject to the interest therein of any Swap Counterparty, 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

Certificate of the Issuer, an Opinion of Counsel and (if required by the TIA)
Independent Certificates in accordance with TIA Sections 314(c) and 314(d)(1)
meeting the applicable requirements of Section 11.1.

     (c)  Each Noteholder, by the acceptance of a Note, acknowledges that from
time to time the Indenture Trustee shall release the lien of this Indenture on
any Trust Student Loan to be sold to (i) the Depositor in accordance with
Section 6 of the Sale Agreement, (ii) to the Servicer in accordance with Section

action pursuant to Section 8.4(a), accompanied by copies of any instruments
involved, and the Indenture Trustee shall also require, except in connection
with any action contemplated by Section 8.4(c), as a condition to such action,
an Opinion of Counsel, in form and substance satisfactory to the Indenture
Trustee, stating the legal effect of any such action, outlining the steps
required to complete the same, and concluding that all conditions precedent to
the taking of such action have been complied with and such action will not
materially and adversely impair the security for the Notes or the rights of the
Noteholders or any Swap Counterparty 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.

event from the Indenture Trustee to the Noteholders shall include notice of the
redemption of Notes by application of such amounts on the next Distribution Date

Section 8.4(c) hereof and Section 6 of the Sale Agreement, Section 3.5 of the
Servicing Agreement or Section 3.11E of the Servicing Agreement, respectively,
so long as the Issuer shall deliver to the Indenture Trustee every six months,
commencing December 31, 2003, an Officers' Certificate of the Issuer stating
that all the dispositions of Collateral described in clauses (A), (B) or (C)
above that occurred during the immediately preceding six calendar months were in
the ordinary course of the Issuer's business and that the proceeds thereof were
applied in accordance with the Basic Documents.

          SECTION 11.2    FORM OF DOCUMENTS DELIVERED TO INDENTURE TRUSTEE. In
any case where several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not necessary that all such matters be
certified by, or covered by the opinion of, only one such Person, or that they
be so certified or covered by only one document, but one such Person may certify
or give an opinion with respect to some matters, and one or more other such
Persons as to other matters, and any such Person may certify or give an opinion
as to such matters in one or several documents.

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

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

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

          SECTION 11.3    ACTS OF NOTEHOLDERS. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken

                                       49
<Page>

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

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

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

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

          SECTION 11.4    NOTICES, ETC., TO INDENTURE TRUSTEE, ISSUER AND RATING
AGENCIES. Any request, demand, authorization, direction, notice, consent, waiver
or Act of Noteholders or other documents provided or permitted by this Indenture
shall be in writing and if such request, demand, authorization, direction,
notice, consent, waiver or Act of Noteholders is to be made upon, given or
furnished to or filed with:

     (a)  The Indenture Trustee by any Noteholder, the Servicer, the
Administrator or by the Issuer shall be sufficient for every purpose hereunder
if made, given, furnished or filed in writing to or with the Indenture Trustee
at: The Bank of New York, 2 North LaSalle St., Suite 1020, Chicago, Illinois,
60602, Attn: Corporate Trust - Structured Finance with a copy to its Corporate
Trust Office.

     (b)  The Issuer by the Indenture Trustee or by any Noteholder shall be
sufficient for every purpose hereunder if in writing and mailed, first-class,
postage prepaid, to the Issuer addressed to: SLM Student Loan Trust 2003-7, in
care of Chase Manhattan Bank USA, National Association, Christiana Center/OPS4,
500 Stanton Christiana Road, Newark, Delaware 19713, Attention: Corporate Trust
Department; with copies to JPMorgan Chase Bank, 450 West 33rd Street 15th Fl.,
New York, New York 10001, Attention: Structured Finance Services; and the
Administrator, 11600 Sallie Mae Drive, Reston, Virginia 20193, Attention: Trust
Administration, or any other address previously furnished in writing to the
Indenture Trustee by the Issuer or the Administrator. The Issuer shall promptly
transmit any notice received by it from the Noteholders to the Indenture
Trustee.

          Notices required to be given to the Rating Agencies by the Issuer, the
Indenture Trustee or the Eligible Lender Trustee shall be in writing, personally
delivered or mailed by

                                       50
<Page>

certified mail, return receipt requested, to (i) in the case of Moody's, at the
following address: ABS Monitoring Department, 99 Church Street, New York, New
York 10007, (ii) in the case of Standard & Poor's, at the following address: 55
Water Street, New York, New York 10041-0003, Attention: Asset Backed
Surveillance Department, 32nd Floor, and (iii) in the case of Fitch, at the
following address: One State Street Plaza, New York, New York 10004, Attention:
Municipal Structured Finance Group; or as to each of the foregoing, at such
other address as shall be designated by written notice to the other parties.

          Notices to any Swap Counterparty will be sent to the address set forth
in the related Swap Agreement.

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

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

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

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

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

          SECTION 11.7    CONFLICT WITH TRUST INDENTURE ACT. If any provision
hereof limits, qualifies or conflicts with another provision hereof that is
required to be included in this

                                       51
<Page>

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 11.8    EFFECT OF HEADINGS AND TABLE OF CONTENTS. The Article
and Section headings herein and the Table of Contents are for convenience only
and shall not affect the construction hereof.

          SECTION 11.9    SUCCESSORS AND ASSIGNS. All covenants and agreements
in this Indenture and the Notes by the Issuer shall bind its successor and
assigns, whether so expressed or not. All agreements of the Indenture Trustee in
this Indenture shall bind the successors, co-trustees and agents (excluding any
legal representatives or accountants) of the Indenture Trustee.

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

          SECTION 11.11   BENEFITS OF INDENTURE. (a) Except as set forth in
paragraphs (b) and (c) below, 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, the Noteholders, 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.

     (b)  The parties to this Indenture acknowledge and agree that each Swap
Cross-Currency Counterparty is an intended third party beneficiary of this
Indenture to the extent of its rights hereunder and under the related Swap
Agreement entered into by the Issuer from time to time and shall be entitled to
enforce such rights.

     (c)  The parties to this Indenture acknowledge and agree that SLM
Corporation, and any permitted transferee, if applicable, is an intended third
party beneficiary of this Indenture to the extent of its rights with respect to
the Call Option as set forth in Section 7 of Appendix A-2 hereto and shall be
entitled to enforce such rights.

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

          SECTION 11.13   GOVERNING LAW. THIS INDENTURE SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS
CONFLICT OF LAW PROVISIONS (OTHER THAN SECTION 5-1401 OF THE NEW YORK GENERAL
OBLIGATIONS LAW), AND THE

                                       52
<Page>

OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS.

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

          SECTION 11.15   RECORDING OF INDENTURE. If this Indenture is subject
to recording in any appropriate public recording offices, such recording is to
be effected by the Issuer and at its expense accompanied by an Opinion of
Counsel (which may be counsel to the Indenture Trustee or any other counsel
reasonably acceptable to the Indenture Trustee) to the effect that such
recording is necessary either for the protection of the Noteholders or any other
Person secured hereunder or for the enforcement of any right or remedy granted
to the Indenture Trustee under this Indenture.

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

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

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

                                       53
<Page>

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

          SECTION 11.19   SUBORDINATION. All rights and interest of each
Cross-Currency Swap Counterparty in the security interest granted to the
Indenture Trustee under this Indenture shall be fully subordinated to the
interests of the Noteholders. No Cross-Currency Swap Counterparty shall have any
rights, implied or otherwise, in the Collateral until after the Outstanding
Amount of the Notes has been reduced to zero and the Noteholders have been paid
all amounts owed to them under this Indenture. Notwithstanding the foregoing,
the provisions of this Section 11.19 shall not modify or otherwise affect the
contractual priority of payments set forth in Section 5.4(b) hereof or Section 2
of the Administration Agreement. More specifically, no Cross-Currency Swap
Counterparty shall have any voting rights or rights to exercise any remedies
under this Indenture until after the Outstanding Amount of the Notes has been
reduced to zero and the Noteholders have been paid all amounts owed to them
under this Indenture. After the Outstanding Amount of the Notes has been reduced
to zero and the Noteholders have been paid all amounts owed to them under this
Indenture, each Cross-Currency Swap Counterparty shall have all of the rights
and obligations, including all voting rights, of the Noteholders set forth in
this Indenture.

Indenture Trustee have caused this Indenture to be duly executed by their
respective officers, thereunto duly authorized and duly attested, all as of the

                                      USAGE

     The following rules of construction and usage shall be applicable to any
instrument that is governed by this appendix (this "Appendix"):

     (a)  All terms defined in this Appendix shall have the defined meanings
when used in any instrument governed hereby and in any certificate or other
document made or delivered pursuant thereto unless otherwise defined therein.

     (b)  As used herein, in any instrument governed hereby and in any
certificate or other document made or delivered pursuant thereto, accounting
terms not defined in this Appendix or in any such instrument, certificate or
other document, and accounting terms partly defined in this Appendix or in any
such instrument, certificate or other document, to the extent not defined, shall
have the respective meanings given to them under generally accepted accounting
principles as in effect on the date of such instrument. To the extent that the
definitions of accounting terms in this Appendix or in any such instrument,
certificate or other document are inconsistent with the meanings of such terms
under generally accepted accounting principles, the definitions contained in
this Appendix or in any such instrument, certificate or other document shall
control.

     (c)  The words "hereof," "herein," "hereunder" and words of similar import

context otherwise requires, to an article, section or subdivision of or an
attachment to such instrument; and the term "including" means "including without
limitation."

at the applicable 91-day Treasury Bill auction, as published in H.15(519) or
otherwise or as reported by the U.S. Department of the Treasury. In the event
that the results of the auctions of 91-day Treasury Bills cease to be published
or reported as provided above, or that no 91-day Treasury Bill auction is held
in a particular week, then the 91-day Treasury Bill Rate in effect as a result
of the last such publication or report will remain in effect until such time, if
any, as the results of auctions of 91-day Treasury Bills will again be so
published or reported or such auction is held, as the case may be. The 91-day
Treasury Bill Rate will be subject to a Lock-In Period of six Business Days.

     "ACCRUAL PERIOD" means, with respect to a Distribution Date and (i) each
class of Floating Rate Notes or a class of Reset Rate Notes that bears interest
at a floating rate of interest, the period from and including the immediately
preceding Distribution Date for such class of Notes, or in the case of the
initial such period, the Closing Date, to but excluding such current
Distribution Date; provided that if more than one Interest Rate Change Date
occurs for any class of Reset Rate Notes within any given Accrual Period, the
related rate of interest for the entire Accrual Period shall be as specified in
the relevant Remarketing Terms Notice, and (ii) a class of Reset Rate Notes that
bears interest at a fixed rate and (x) is denominated in U.S. Dollars, the
period from and including the 15th day of the month of the immediately preceding
quarterly Distribution Date, to and including the 14th day of the month of the
then-current Distribution Date for that class, or (y) is denominated in a
currency other than U.S. Dollars, (A) the period from and including the 15th day
of the month of the immediately preceding Distribution Date, to and including
the 14th day of the month of the then-current Distribution Date or (B) as
otherwise specified on the related Schedule A of such class of Reset Rate Notes;
provided, however, that the initial Accrual Period for the Class A-5B Notes will
begin on the Closing Date and end on June 14, 2004.

     "ACCUMULATION ACCOUNT" means each account designated as such, established
and maintained pursuant to Section 2.3A.4 of the Administration Agreement.

     "ACT" means the Securities Act of 1933, as amended.

number of days elapsed in a year of 360 days.

basis of the actual number of days elapsed in a year of 365 days, or 366 days
for every day in a leap year.

basis:

          (1)  where the number of days in the relevant Accrual Period is equal
     to or shorter than the Determination Period during which such Accrual
     Period ends, the number of days in such Accrual Period divided by the
     product of (A) the number of days in such Determination Period and (B) the
     number of Distribution Dates that would occur in one calendar year; or

          (2)  where the Accrual Period is longer than the Determination Period
     during which the Accrual Period ends, the sum of:

equally close to the designated CMT index maturity, the Administrator will
obtain quotations for the Treasury Note with the shorter remaining term to
maturity, (v) if three or four but not five leading primary United States
government securities dealers are quoting as described in the prior paragraph,
then the CMT Rate for the relevant Interest Rate Determination Date will be
based on the average of the bid rates obtained and neither the highest nor the
lowest of those quotations will be eliminated, or (vi) if fewer than three

Administrator are quoting as described in (v) above, the CMT Rate will remain

the definition of "Failed Remarketing" are applicable. In order to prevent the
declaration of a Failed Remarketing, the Remarketing Agents will have the

Rate Notes will apply for the related Reset Period and (iii) a Reset Period of

shall also apply.

     (c)  If there is a Failed Remarketing of a class of Reset Rate Notes, the

of such three month Reset Period, the holder of the Call Option may either
remarket the related class of Reset Rate Notes pursuant to the remarketing
procedures set forth herein and in the Remarketing Agreement, or retain that
class for one or more successive three-month Reset Periods at the then-current

other related costs and expenses associated with such remarketing, other than
the fees of the Remarketing Agents, as more fully set forth in Section 3 of the
Remarketing Agreement.

desire to hold their Reset Rate Notes for the next Reset Period at a rate of
interest not less than the All Hold Rate and on the terms set forth in the
related Remarketing Terms Notice, at any time on or after the Remarketing Terms
Determination Date until the Notice Date. Such Hold Notice may be delivered as
an oral statement to a Remarketing Agent, if subsequently confirmed in writing
within 24 hours, which confirmation may be in the form of an e-mail if timely
received by the applicable Remarketing Agent. If a Reset Rate Noteholder does
not timely deliver a Hold Notice to a Remarketing Agent (such Hold Notice not to
be considered delivered until actually received by such Remarketing Agent), that
Reset Rate Noteholder will be deemed to have tendered for remarketing 100% of
the Outstanding Amount of its related class of Reset Rate Notes. Any duly
delivered Hold Notice will be irrevocable, but will be subject to a mandatory
tender of the applicable Reset Rate Notes pursuant to any exercise of the
related Call Option. All of the Reset Rate Notes of an applicable class, whether
tendered or not, will bear interest during any Reset Period on the same terms.

     Section 9.     SPREAD DETERMINATION DATE: (a) On each Spread Determination
Date, unless a Failed Remarketing has been declared or the holder of the Call
Option has delivered the Call Option Notice, the Administrator, the Trust and
the Remarketing Agents will enter into a Supplemental Remarketing Agency
Agreement.

     (b)  If pursuant to the Remarketing Terms Notice, the Remarketing Agents,
in consultation with the Administrator, have determined that a class of Reset
Rate Notes is to be reset to bear a fixed rate of interest, then the applicable
fixed rate of interest for the corresponding Reset Period will be determined on
the Spread Determination Date by adding (i) the applicable spread as determined
by the Remarketing Agents on the Spread Determination Date and (ii) the yield to
maturity on the Spread Determination Date of the applicable fixed rate pricing
benchmark, selected by the Remarketing Agents, as having an expected weighted
average life based on a scheduled maturity at the next Reset Date, which would
be used in accordance with customary financial practice in pricing new issues of
asset-backed securities of comparable average life; provided that such fixed
rate of interest will in no event be lower than the related All Hold Rate, if
applicable. The Remarketing Agents shall determine the applicable

                                 Appendix A-2-7
<Page>

fixed rate of interest for such class of Reset Rate Notes (by reference to the
applicable fixed rate pricing benchmark plus or minus the spread determined on
the Remarketing Terms Determination Date) on each Spread Determination Date
irrespective of whether no remarketing will occur as the result of the
application of the All Hold Rate, if applicable. In addition, on the related
Spread Determination Date, the Remarketing Agents, in consultation with the
Administrator, shall determine the Supplemental Interest Account Deposit Amount
for that class.

     (c)  If pursuant to the Remarketing Terms Notice, the Remarketing Agents,
in consultation with the Administrator, have determined that a class of Reset
Rate Notes is to be reset to bear a floating rate of interest, then, on the
related Spread Determination Date, the Remarketing Agents will establish the
applicable Spread to be added or subtracted from the applicable Index; provided
that such floating rate of interest will in no event be lower than the related
All Hold Rate, if applicable.

the Trust shall enter into either (i) a Cross-Currency Swap Agreement, if the
related class of Reset Rate Notes is to be reset in Foreign Exchange Mode, or
(ii) an Interest Swap Agreement if the related class of Reset Rate Notes is to

rate other than one based on LIBOR or a Commercial Paper Rate, with an Eligible
Swap Counterparty. In addition, if the related class of Reset Rate Notes is to
be reset in Foreign Exchange Mode, on the related Reset Date the Remarketing
Agents shall cause a Swap Agent to enter into a Reset Date Currency Swap
Agreement with an Eligible Swap Counterparty.

     (e)  On or immediately following the Spread Determination Date, the
Remarketing Agents will communicate in writing (including facsimile or other
electronic transmission if in accordance with each Clearing Agency's standard
procedures) the contents of the Spread Determination Notice to each Clearing
Agency (and the Luxembourg Stock Exchange if the related class of Reset Rate
Notes on then listed on the exchange) with instructions to distribute such
notices to its related participants, or to the related Reset Rate Noteholders,
as applicable, the Indenture Trustee and the Rating Agencies. The Spread
Determination Notice will contain: (i) the determined Spread or fixed rate of
interest, as the case may be, or, if applicable, a statement that the All Hold
Rate or the Failed Remarketing Rate will be in effect for the immediately
following Reset Period, (ii) any applicable currency exchange rate, (iii) if
applicable, the identity of any selected Swap Counterparty or Counterparties,
and Swap Agent or Agents, if applicable, (iv) if applicable, the floating rate
(or rates) of interest to be due to each selected Swap Counterparty with respect
to each Distribution Date during the immediately following Reset Period and (v)
any other information that the Administrator or the Remarketing Agents deem
applicable. Furthermore, for each class of Reset Rate Notes to be reset in
Foreign Exchange Mode, the currency exchange rate, the Extension Rate due to the
related Swap Counterparty and the Failed Remarketing Rate applicable to such
class for the immediately following Reset Period will be determined pursuant to
the terms of the related Cross-Currency Swap Agreement and contained in the
Spread Determination Notice. In addition, if required for the immediately
following Reset Period, on or before the related Spread Determination Date the
Administrator will arrange for new or additional securities identification codes
to be obtained as required.

     deposited into the related Accumulation Account and paid to the related
     Swap Counterparty on or about the next Reset Date as set forth in the
     related Cross-Currency Swap Agreement (including all sums required to be

     a fraction determined by the number of days in the applicable Accrual
     Period and the applicable Day Count Basis, and (B) the applicable non-U.S.
     Dollar currency equivalent of the U.S. Dollars such Swap Counterparty
     concurrently receives from the Trust as a payment of principal allocated to
     the related class of Reset Rate Noteholders (including, on the related

     remarketing or an exercise of the related Call Option) interest at the
     related interest rate from and including the related Reset Date to, but
     excluding, the second Business Day following such Reset Date. For any Reset
     Period following a Reset Date upon which a Failed Remarketing has occurred,
     up to any including the Reset Date resulting in a successful remarketing or

<Page>

     principal to that class of Reset Rate Noteholders will be made on the
     second Business Day following the related Reset Date without the payment of

     (b)  In addition, if a class of Reset Rate Notes is to be reset in Foreign
Exchange Mode, on the related Reset Date, the Remarketing Agents will appoint
one or more Swap Agents and cause such Swap Agents to enter into one or more
Reset Date Currency Swap Agreements with one or more Eligible Swap
Counterparties for the next Reset Period. Each Reset Date Currency Swap
Agreement will share the same currency exchange rate as the related
Cross-Currency Swap Agreement.

          (i)     On the effective date of any Reset Date Currency Swap
     Agreement (except with respect to the Initial Reset Date Currency Swap
     Agreement), (A) the Remarketing Agents will deliver to the related Swap
     Agent, for further delivery to the related Swap Counterparty, all secondary

     Period ending on such Reset Date, all U.S. Dollar secondary trade sale
     proceeds received from the Remarketing Agents that the Remarketing Agents
     either received directly from the purchasers of such Reset Rate Notes (if
     remarketed in U.S. Dollars) or from the Swap Agent with respect to the
     Reset Date Currency Swap Agreement commencing on such Reset Date (if
     remarketed in Foreign Exchange Mode, as described in subparagraph (i)
     above), and (B) in return, the related Swap Counterparty for the related
     Reset Date Currency Swap Agreement in effect for the Reset Period ending on

     (c)  If a class of Reset Rate Notes is to be reset in U.S. Dollars, and a
Swap Agreement is required pursuant to Section 1(c) above, then the
Administrator will enter into (not in its individual capacity, but solely as
Administrator on behalf of the Trust) or will instruct the Eligible Lender
Trustee to enter into (not in its individual capacity, but solely as Eligible
Lender Trustee), an Interest Swap Agreement for the next Reset Period to
facilitate the Trust's ability to pay applicable interest at the related
interest rate.

          (i)     Each Swap Counterparty which is party to the related Interest
     Swap Agreement will be entitled to receive on each Distribution Date, an
     interest rate of Three-Month LIBOR, plus or minus a spread, as determined
     from the bidding process described in Section 10(d) below, multiplied by
     the Outstanding Amount of the related class of Reset Rate Notes and
     multiplied by a fraction determined by the number of days in the applicable
     Accrual Period and the applicable Day Count Basis.

          (ii)    In addition, each related Swap Counterparty which is a party
     to the related Interest Swap Agreement will be obligated to pay to the
     Trust on each Distribution Date, the applicable rate of interest on the
     related class of Reset Rate Notes multiplied by the Outstanding Amount of
     the related class of Reset Rate Notes and multiplied by a fraction
     determined by the number of days in the applicable Accrual Period and the
     applicable Day Count Basis.

     (d)  Other than with respect to the Initial Swap Agreements, the applicable
Remarketing Agents, in consultation with the Administrator, in determining the
Swap Counterparty to the required Swap Agreement, will solicit bids from at
least three Eligible Swap Counterparties and will select the lowest of these
bids to provide the interest rate swap and/or currency exchange swap(s). If the
lowest bidder specifies a notional amount that is less than the Outstanding
Amount of the related class of Reset Rate Notes, the applicable Remarketing
Agents, in consultation with the Administrator, may select more than one
Eligible Swap Counterparty, but only to the extent that such additional Eligible
Swap Counterparties have provided the next lowest received bid or bids, and
enter into more than one Swap Agreement that result in the Rating Agency
Condition being satisfied. On or before the Spread Determination Date, the
Remarketing Agents, in consultation with the Administrator, will select the Swap
Counterparty or Counterparties and any related Swap Agents and the cause any
such Swap Agent or Swap Agents to enter into the required Swap Agreements on the
related Reset Date for the upcoming Reset Period.

     (e)  Other than with respect to the Initial Swap Agreements, it is a
condition precedent to the entering into of any Swap Agreement and the setting
of the amount to be paid to the related Swap Counterparty that the Rating Agency
Condition is satisfied. No Swap Agreement will be entered into or caused to be
entered into by the Trust, the Administrator on its behalf, the Remarketing
Agents or a Swap Agent on their behalf, for any Reset Period where either the
related Call Option has been exercised or a Failed Remarketing has been
declared.

     (f)  Each such Swap Agreement, will terminate at the earliest to occur of
(i) the next succeeding Reset Date for which there is a successful remarketing,
(ii) the related Reset Date for which the related Call Option is exercised,
(iii) the Distribution Date on which the Outstanding Amount of the Reset Rate
Notes is reduced to zero (including as the result of the optional

                                 Appendix A-2-11
<Page>

purchase of the remaining Trust Student Loans by the Servicer or an auction of
the Trust Student Loans by the Indenture Trustee) or (iv) the Maturity Date of
the related class of Reset Rate Notes. No Cross-Currency Swap Agreement or Reset
Date Currency Swap Agreement will terminate solely due to the declaration of a
Failed Remarketing.

     (g)  With respect to each Cross-Currency Swap Agreement, and in the event
that a Failed Remarketing is declared, the rate of interest due to the related
Swap Counterparty from the Trust on each Distribution Date will be increased to
the related Extension Rate and the rate due to the Trust from the related Swap
Counterparty will change to equal the related Failed Remarketing Rate.

     Section 11.    ACCUMULATION ACCOUNT; SUPPLEMENTAL INTEREST ACCOUNT: (a) If,
on any Distribution Date, principal would be payable to a class of Reset Rate
Notes then bearing interest at a fixed rate (including without limitation, with
respect to the Class A-5B Notes during the initial Reset Period), that principal
(subject to sufficient Available Funds therefor) will be allocated to that class
of Reset Rate Notes and deposited into the related Accumulation Account, where
it will remain until the next Reset Date for that class (except that if a class
of Reset Rate Notes is in Foreign Exchange Mode, principal will be paid
according to the provisions of Section 10(a)(i) and (a)(ii) above), unless an
Event of Default under the Indenture or a sale of the Trust Estate pursuant to
Section 6.1 of the Administration Agreement has occurred (in which case the
Indenture Trustee will distribute all sums on deposit therein (exclusive of
Investment Earnings) to the related Reset Rate Noteholders in accordance with
the provisions of Section 5.4SECTION 11.21 of the Indenture or Section 6.1 of
the Administration Agreement, as applicable).

     (b)  On each Reset Date for a class of Reset Rate Notes that bore interest
at a fixed rate during the preceding Reset Period (including without limitation,
on the related Initial Reset Date for the Class A-5B Notes), all sums, if any,
then on deposit in the related Accumulation Account, including any allocation of
principal made on the same date, but less any Investment Earnings, will be
distributed by the Indenture Trustee, at the direction of the Administrator, as
set forth in Section 2.7C of the Administration Agreement, (x) to the holders of
that class of Reset Rate Notes, as of the related Record Date, or (y) if a class
of Reset Rate Notes is in Foreign Exchange Mode (including the Class A-5B Notes
during the initial Reset Period), to the related Cross-Currency Swap
Counterparty or Counterparties for the benefit of such Reset Rate Noteholders as
of the related Record Date pursuant to the provisions of Section 10(a)(i) and
(a)(ii) above, in reduction of principal of such class; provided, that, in the
event on any Distribution Date the amount on deposit in the related Accumulation
Account (excluding any Investment Earnings) would equal the Outstanding Amount
of that class, no additional amounts will be deposited into the related
Accumulation Account and all amounts therein, less any Investment Earnings, will
be distributed by the Indenture Trustee, at the direction of the Administrator,
as set forth in Section 2.7C of the Administration Agreement, on the next
related Reset Date to the related Reset Rate Noteholders or the related
Cross-Currency Swap Counterparty (as applicable), and on such Reset Date that
class of Reset Rate Notes will no longer be Outstanding. Amounts on deposit in
an Accumulation Account (exclusive of Investment Earnings) may be used only to
pay principal on the related class of Reset Rate Notes (or to the related
Cross-Currency Swap Counterparty or Counterparties) and for no other purpose. On
each Distribution Date, all Investment Earnings on deposit in each Accumulation

                                 Appendix A-2-12

Account will be withdrawn by the Indenture Trustee, at the direction of the
Administrator, as set forth in Section 2.8.4B.4 of the Administration Agreement,
and deposited into the Collection Account.

     (c)  The Indenture Trustee, subject to sufficient available funds therefor,
at the direction of the Administrator and pursuant to Section 2.8.5B of the
Administration Agreement, will deposit into any Supplemental Interest Account,
the related Supplemental Interest Account Deposit Amount. On each Distribution
Date, all sums (which shall include Investment Earnings) on deposit in each
Supplemental Interest Account will be withdrawn by the Indenture Trustee, at the
direction of the Administrator, as set forth in Section 2.8.5C of the
Administration Agreement, and deposited into the Collection Account.

     Section 12.    REMARKETING AGENTS; SWAP AGENT; REMARKETING FEE ACCOUNT:
(a) The initial Remarketing Agents, appointed pursuant to the terms of the
Remarketing Agreement, are Credit Suisse First Boston LLC, J.P. Morgan
Securities Inc., and Morgan Stanley & Co. Incorporated. The terms and conditions
of the Remarketing Agreement will govern the duties and obligations of the
Remarketing Agents and each Swap Agent. The Administrator, the Trust and the
Remarketing Agents will enter into on each related (A) Remarketing Terms
Determination Date, an Initial Remarketing Agency Agreement, in form and
substance substantially the same as Appendix B to the Remarketing Agreement,
unless (i) a Failed Remarketing is declared, or (ii) the holder of the Call
Option has delivered the related Call Option Notice on or prior to such date;
and (B) Spread Determination Date, a Subsequent Remarketing Agency Agreement, in
form and substance substantially the same as Appendix C to the Remarketing
Agreement, unless (i) a Failed Remarketing is declared, (ii) the holder of the
Call Option has delivered the related Call Option Notice on or prior to such
date, or (iii) if applicable, 100% of the related Reset Rate Noteholders have
timely delivered a Hold Notice and the All Hold Rate will apply for the next
related Reset Period.

     (b)  If a class of Reset Rate Notes is in Foreign Currency Mode or will be
reset into Foreign Currency Mode, then pursuant to Section 13 of the Remarketing
Agreement, the Remarketing Agents shall appoint one or more Swap Agents to act
as agent for the Remarketing Agent and for the benefit of the related Reset Rate
Noteholders, and instruct each Swap Agent to enter into a related Reset Date
Currency Swap Agreement. The initial Swap Agent, appointed by the Remarketing
Agents pursuant to the Remarketing Agreement, is CDC IXIS Capital Markets,
London Branch. The initial Swap Agent shall be entitled to receive the
Remarketing Agents' Upfront Fee pursuant to Section 3(c) of the Remarketing
Agreement. The duties and obligations of the Swap Agent are set forth in the
Remarketing Agreement.

     (c)  Excluding all Reset Rate Notes of a class for which a Remarketing
Agent has received a timely delivered Hold Notice, if applicable (or if the
holder of the Call Option has delivered the related Call Option Notice), on the
Reset Date that commences each Reset Period, each related Reset Rate Note will
be automatically tendered, or deemed tendered, to the relevant Remarketing Agent
for remarketing by such Remarketing Agent on the Reset Date at 100% of its
Outstanding Amount. If the related class of Reset Rate Notes is held in
book-entry form, subject to Section 12(c) below, 100% of the Outstanding Amount
of such Reset Rate Notes will be paid by the Remarketing Agents in accordance
with the standard procedures of the applicable Clearing Agencies.

                                 Appendix A-2-13
<Page>

     (d)  The Remarketing Agents will attempt, on a reasonable efforts basis and
in accordance with the terms and conditions of the Remarketing Agreement and the
related Remarketing Agency Agreement, to remarket the tendered Reset Rate Notes
of the applicable class at a price equal to 100% of the Outstanding Amount of
the related class of Reset Rate Notes so tendered.

     (e)  Purchasers of the related class of Reset Rate Notes will be credited
with their positions on the applicable Reset Date with respect to positions held
through DTC or on the next Business Day with respect to positions held through
the European Clearing Systems. No payment delay to existing Reset Rate
Noteholders holding U.S. Dollar denominated Reset Rate Notes through DTC will
occur on the related Reset Date for any class denominated in U.S. Dollars during
the immediately following Reset Period (including the Class A-5A Notes during
its initial Reset Period).

     (f)  Each of the Remarketing Agents, in its individual or any other
capacity, may buy, sell, hold and deal in any class of the Reset Rate Notes,
including, but not limited to, purchasing any tendered Reset Rate Notes as part
of the remarketing process. Any Remarketing Agent that owns a Reset Rate Note
may exercise any vote or join in any action which any beneficial owner of such
class may be entitled to exercise or take with like effect as if it did not act
in any capacity under the Remarketing Agreement or Remarketing Agency Agreement.
Any Remarketing Agent, in its individual capacity, either as principal or agent,
may also engage in or have an interest in any financial or other transaction
with the Trust, the Depositor, the Servicer, the Indenture Trustee (in its
individual capacity), the Eligible Lender Trustee (in its individual capacity)
or the Administrator as freely as if it did not act in any capacity under the
Remarketing Agreement or any Remarketing Agency Agreement. No Reset Rate
Noteholder or beneficial owner of any Reset Rate Note will have any rights or
claims against any Remarketing Agent as a result of such Remarketing Agent's not
purchasing any tendered Reset Rate Note, which results in the declaration of a
Failed Remarketing.

     (g)  Each of the Remarketing Agents will be entitled to receive a fee in
connection with their services rendered for each successful remarketing of a
class of Reset Rate Notes in the amount set forth in the Remarketing Agreement
and the related Remarketing Agency Agreement. Subject to the terms and
conditions set forth in the Remarketing Agreement, the Administrator, in its
sole discretion, may change the Remarketing Agents for any class of Reset Rate
Notes for any Reset Period at any time on or before the related Remarketing
Terms Determination Date. In addition, the Administrator will appoint one or
more additional Remarketing Agents, if necessary, for a Reset Date when the
related class of Reset Rate Notes will be remarketed in a non-U.S. Dollar
currency. Furthermore, a Remarketing Agent may resign at any time provided that
no resignation may become effective on a date that is later than 15 Business
Days prior to a Remarketing Terms Determination Date.

     (h)  In accordance with Section 2.8.3 of the Administration Agreement, on
the Closing Date, the Trust will establish the Remarketing Fee Account as an
asset of the Trust in the name of the Indenture Trustee for the benefit of the
Remarketing Agents and the related Reset Rate Noteholders. The fees associated
with each successful remarketing will be payable directly to the Remarketing
Agents from amounts on deposit from time to time in the Remarketing Fee Account.
On each applicable Distribution Date, Available Funds will be deposited into the

                                 Appendix A-2-14
<Page>

Remarketing Fee Account, in the priority set forth in Section 2.7C of the
Administration Agreement, in an amount up to the Quarterly Funding Amount;
provided, that if the amount on deposit in the Remarketing Fee Account, after
the payment of any remarketing fees therefrom, exceeds the sum of the Reset
Period Target Amount for all classes of Reset Rate Notes, such excess will be
withdrawn on the related Distribution Date, deposited into the Collection
Account and included in Available Funds for that Distribution Date. All
Investments Earnings on deposit in the Remarketing Fee Account will be withdrawn
on the next Distribution Date, deposited into the Collection Account and
included in Available Funds for that Distribution Date. In the event that the
fees owed to any Remarketing Agent on a Reset Date exceeds the amount then on
deposit in the Remarketing Fee Account, such shortfall shall be paid from
Available Funds on future Distribution Dates in the priority set forth in
Section 2.7C of the Administration Agreement. The Trust shall also be
responsible for certain remarketing costs and expenses to the extent set forth
in Section 3 of the Remarketing Agreement, which shall be paid on each
Distribution Date, to the extent of Available Funds, at the priority set forth
in Section 2.7C of the Administration Agreement.

     Section 13.    ELIGIBLE LENDER TRUSTEE: The Eligible Lender Trustee is
hereby authorized and directed to execute and deliver, not in its individual
capacity, but solely as Eligible Lender Trustee on behalf of the Trust, the
Remarketing Agreement, any Swap Agreements, and all Remarketing Agency
Agreements as the Administrator, in writing and from time to time, shall
instruct the Eligible Lender Trustee to execute. The Eligible Lender Trustee
shall not be liable to any party, any third party or any Noteholder for any such
actions taken at the written instruction of the Administrator. Notwithstanding
the foregoing, in the event that the Eligible Lender Trustee declines or fails
to execute or deliver any such document, instrument, certificate or agreement as
instructed by the Administrator, the Administrator is hereby authorized, in its
sole discretion, to execute and deliver, not in its individual capacity but
solely as Administrator on behalf of the Trust, all such required documents,
instruments, certificates and agreements. The foregoing authorization shall
represent a limited power of attorney granted by the Trust to the Administrator
to act on its behalf and the Administrator shall not be liable to any party, any
third party or any Noteholder for any such actions taken in good faith and in
accordance with these Reset Rate Note Procedures.

Certificates, or vice versa (other than on a Reset Date where such class is
being reset from being denominated in U.S. Dollars to Foreign Currency Mode, or
vice versa), shall be null and void and of no effect.

pursuant to Rule 144A, to a person whom the seller reasonably believes is a QIB

others also must be QIB's), (3) if such transferee is a non-U.S. Person (as
defined in Regulation S) outside the United States of America, that such

     "THIS NOTE HAS NOT BEEN AND WILL NOT BE REGISTERED UNDER THE SECURITIES ACT
     OF 1933, AS AMENDED (THE "SECURITIES ACT"), ANY STATE SECURITIES OR "BLUE
     SKY" LAWS OR ANY SECURITIES LAWS OF ANY OTHER JURISDICTION, AND, AS A

          Upon the transfer, exchange or replacement of a Rule 144A Certificate
or a Regulation S Certificate bearing the applicable legends set forth above, or
upon specific request for removal of the legends, the Trust or the Registrar
will deliver only replacement Rule 144A Certificates or Regulation S
Certificates, as the case may be, that bear such applicable legends, or will
refuse to remove such applicable legends, unless there is delivered to the Trust
and the Registrar such satisfactory evidence (which may include a legal opinion)
as may reasonably be required by the Trust and the Indenture Trustee that
neither the applicable legends nor the restrictions on transfer set forth
therein are required to ensure compliance with the provisions of the Securities
Act.

     Whenever a Global Note Certificate is to be exchanged for Individual Note
Certificates, such Individual Note Certificates will be issued within five
business days of delivery to the Registrar of the information and any required
certification described in the preceding paragraph against the surrender of the
relevant Global Note Certificate at the specified office of the Registrar. Such
exchange shall be effected in accordance with the regulations concerning the
transfer and registration from time to time relating to the Reset Rate Notes and
shall be effected without charge, but against such indemnity as the Registrar
may require in respect of any tax or other duty of whatsoever nature which may
be levied or imposed in connection with such exchange.

     Each Reset Rate Noteholder or Note Owner, as applicable, of such Reset Rate
Note, by its acceptance of a Reset Rate Note or a beneficial interest therein,
respectively, also agrees that it will transfer such a Reset Rate Note or
beneficial interest therein, as the case may be, only as provided herein and in
accordance with the Indenture. In addition, by acceptance of any Reset Rate Note
or beneficial interest therein, as applicable, each proposed transferee thereof
is hereby deemed to have agreed with the conditions set forth in the applicable
legend and agreed, by virtue of its acceptance of such Reset Rate Note or
beneficial interest therein, as the case may be, to indemnify the Administrator,
the Depositor, the Servicer, the Indenture Trustee, the Eligible Lender Trustee,
the Remarketing Agents (in the event such transfer is made pursuant to a
successful remarketing on a related Reset Date) and the Issuer against any and
all liability that may result if such transfer is not made in a manner
consistent with the restrictions set forth in the applicable legend. In addition
to any applicable restrictions in the Indenture, with respect to the transfer
and registration of transfer of any Reset Rate Note (an "Individual Note")
registered in the name of a Reset Rate Noteholder other than DTC or its nominee
or Euroclear or Clearstream, Luxembourg or their joint nominee, as the case may
be, to a transferee that takes delivery in the form of a Individual Note, the
Indenture Trustee shall register the transfer of such Individual Note if (i) (A)
the requested transfer is being made to a transferee who has provided the
Indenture Trustee and the Administrator with a Transferee Certificate,
substantially in the form attached as Annex 1 hereto, or (B) such transferee has
provided comparable evidence as to its QIB status or that such transfer is being
made in compliance with Regulation S and that it is a Non-U.S. Person (as
defined in Regulation S), and (ii) the applicable transferor has provided the
Indenture Trustee and the Administrator with a Transferor Letter, substantially
in the form of Annex 2 hereto.

The Notes are subject to all terms of the Indenture.

          The Class A-1 Notes are and will be equally and ratably secured by the
Collateral pledged as security therefor as provided in the Indenture. On any
Distribution Date, the Class A-1 Notes are prior in order of principal payment
to the Class A-2, Class A-3, Class A-4, Reset Rate Notes, and, up to the
applicable Class A Noteholders' Principal Distribution Amount, the Class B
Notes. The Class A Notes are senior to the Class B Notes, as and to the extent
provided in the Indenture.

          Principal of the Class A-1 Notes shall be payable on each Distribution
Date in an amount described on the face hereof. "Distribution Date" means the
15th day of each March, June, September and December or, if any such date is not
a Business Day, the next succeeding Business Day, commencing September 2003.

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

          Interest on the Class A-1 Notes shall be payable on each Distribution
Date on the principal amount outstanding of the Class A-1 Notes until the
principal amount thereof is paid in full, at a rate per annum equal to the Class
A-1 Rate. The "Class A-1 Rate" for each Accrual Period, other than the initial
Accrual Period, shall be equal to Three-Month LIBOR as determined on the second
Business Day before the beginning of that Accrual Period plus 0.01%. For the
initial Accrual Period, the "Class A-1 Rate" shall be the Initial Accrual Rate
plus 0.01%.

          Payments of interest on this Note on each Distribution Date, together
with the installment of principal, if any, to the extent not in full payment of
this Note, shall be made by check mailed to the Person whose name appears as the
Registered Holder of this Note (or one or

                                   Exhibit A-4
<Page>

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

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

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

          Each Noteholder or Note Owner, by acceptance of a Note or, in the case
of a Note Owner, a beneficial interest in the Note, covenants and agrees that no
recourse may be taken, directly or indirectly, with respect to the obligations
of the Issuer or the Indenture Trustee on the Notes or under the Indenture or
any certificate or other writing delivered in connection therewith, against (i)
the Indenture Trustee or the Eligible Lender Trustee in its individual capacity,
(ii) any owner of a beneficial interest in the Issuer or (iii) any partner,
owner, beneficiary, agent, officer, director or employee of the Indenture
Trustee or the Eligible Lender Trustee in its individual capacity, any holder or
owner of a beneficial interest in the Issuer, the Eligible Lender Trustee or

                                   Exhibit A-5
<Page>

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

          Upon acquisition or transfer of a beneficial interest in any
Book-Entry Note by, for or with the assets of, an employee benefit plan or other
retirement arrangement subject to Section 406 of ERISA or Section 4975 of the
Code, such Note Owner shall be deemed to have represented that such acquisition
or purchase will not constitute or otherwise result in a non-exempt prohibited
transaction in violation of Section 406 of ERISA or Section 4975 of the Code
which is not covered by a class or other applicable exemption. Any transfer
found to have been made in violation of such deemed representation shall be null
and void and of no effect.

          Each Noteholder or Note Owner, by acceptance of a Note or, in the case
of a Note Owner, a beneficial interest in a Note, covenants and agrees that by
accepting the benefits of the Indenture such Noteholder or Note Owner will not
at any time institute against the Depositor or the Issuer, or join in any
institution against the Depositor or the Issuer of, any bankruptcy,
reorganization, arrangement, insolvency, receivership or liquidation proceedings
or other proceedings under any United States Federal or state bankruptcy or
similar law in connection with any obligations relating to the Notes, the
Indenture or the other Basic Documents.

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

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

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

                                   Exhibit A-6
<Page>

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

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

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

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

          Anything herein to the contrary notwithstanding, except as expressly
provided in the Basic Documents, neither The Bank of New York, in its individual
capacity, Chase Manhattan Bank USA, National Association in its individual
capacity, any owner of a beneficial interest in the Issuer, nor any of their
respective partners, beneficiaries, agents, officers, directors, employees or
successors or assigns shall be personally liable for, nor shall recourse be had
to any of them for, the payment of principal of or interest on, or performance
of, or omission to perform, any of the covenants, obligations or
indemnifications contained in this Note or the Indenture; it being expressly
understood that said covenants, obligations and indemnifications have been made
by the Eligible Lender Trustee for the sole purposes of binding the interests of
the Eligible Lender Trustee in the assets of the Issuer. The Noteholder of this
Note by the acceptance hereof agrees that, except as expressly provided in the
Basic Documents, in the case of an Event of Default under the Indenture, the
Noteholder shall have no claim against any of the foregoing for any deficiency,
loss or claim therefrom; PROVIDED, HOWEVER, that nothing contained herein shall
be taken to prevent recourse to, and enforcement against, the assets of the
Issuer for any and all liabilities, obligations and undertakings contained in
the Indenture or in this Note.

<Page>

                                [REVERSE OF NOTE]

          This Note is one of a duly authorized issue of Notes of the Issuer,
designated as its Floating Rate Class A-2 Student Loan-Backed Notes (the "Class
A-2 Notes"), which, together with the Issuer's Floating Rate Class A-1 Student
Loan-Backed Notes (the "Class A-1 Notes"), Floating Rate Class A-3 Student
Loan-Backed Notes (the "Class A-3 Notes"), Floating Rate Class A-4 Student
Loan-Backed Notes (the "Class A-4 Notes"), Reset Rate Class A-5A Student
Loan-Backed Notes (the "Class A-5A Notes"), Reset Rate Class A-5B Student
Loan-Backed Notes (the "Class A-5B Notes" and, together with the Class A-5A
Notes, the "Reset Rate Notes" and, the Reset Rate Notes together with the Class
A-1, Class A-2, Class A-3 and Class A-4 Notes, the "Class A Notes"), and
Floating Rate Class B Student Loan-Backed Notes (the "Class B Notes" and,
together with the Class A Notes, the "Notes"), are issued under and secured by
the Indenture, to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights and
obligations thereunder of the Issuer, the Indenture Trustee and the Noteholders.
The Notes are subject to all terms of the Indenture.

          The Class A-2 Notes are and will be equally and ratably secured by the
Collateral pledged as security therefor as provided in the Indenture. On any
Distribution Date, the Class A-1 Notes are prior in order of principal payment
to the Class A-2 Notes, and the Class A-2 Notes are prior in order of principal
payment to the Class A-3 Notes, Class A-4 Notes, the Reset Rate Notes and, up to
the applicable Class A Noteholders' Principal Distribution Amount, the Class B
Notes. The Class A Notes are senior to the Class B Notes, as and to the extent
provided in the Indenture.

          Principal of the Class A-2 Notes shall be payable on each Distribution
Date in an amount described on the face hereof. "Distribution Date" means the
15th day of each March, June, September and December or, if any such date is not
a Business Day, the next succeeding Business Day, commencing September 2003.

          As described on the face hereof, the entire unpaid principal amount of
this Note shall be due and payable on the Class A-2 Maturity Date.
Notwithstanding the foregoing, the entire unpaid principal amount of the Notes
shall be due and payable on the date on which (i) an Event of Default shall have
occurred and be continuing and (ii) the Indenture Trustee or the Noteholders
representing not less than a majority of the Outstanding Amount of the Notes
shall have declared the Notes to be immediately due and payable in the manner
provided in Section 5.2 of the Indenture. All principal payments on the Class
A-2 Notes shall be made pro rata to the Noteholders entitled thereto.

          Interest on the Class A-2 Notes shall be payable on each Distribution
Date on the principal amount outstanding of the Class A-2 Notes until the
principal amount thereof is paid in full, at a rate per annum equal to the Class
A-2 Rate. The "Class A-2 Rate" for each Accrual Period, other than the initial
Accrual Period, shall be equal to Three-Month LIBOR as determined on the second
Business Day before the beginning of that Accrual Period plus 0.03%. For the
initial Accrual Period, the "Class A-2 Rate" shall be the Initial Accrual Rate
plus 0.03%.

          Payments of interest on this Note on each Distribution Date, together
with the installment of principal, if any, to the extent not in full payment of
this Note, shall be made by

                                  Exhibit A-12
<Page>

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

          The Issuer shall pay interest on overdue installments of interest on
this Note at the Class A-2 Rate to the extent lawful.

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

          Each Noteholder or Note Owner, by acceptance of a Note or, in the case
of a Note Owner, a beneficial interest in the Note, covenants and agrees that no
recourse may be taken, directly or indirectly, with respect to the obligations

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

          Upon acquisition or transfer of a beneficial interest in any
Book-Entry Note by, for or with the assets of, an employee benefit plan or other
retirement arrangement subject to Section 406 of ERISA or Section 4975 of the
Code, such Note Owner shall be deemed to have represented that such acquisition
or purchase will not constitute or otherwise result in a non-exempt prohibited
transaction in violation of Section 406 of ERISA or Section 4975 of the Code
which is not covered by a class or other applicable exemption. Any transfer
found to have been made in violation of such deemed representation shall be null
and void and of no effect.

          Each Noteholder or Note Owner, by acceptance of a Note or, in the case
of a Note Owner, a beneficial interest in a Note, covenants and agrees that by
accepting the benefits of the Indenture such Noteholder or Note Owner will not
at any time institute against the Depositor or the Issuer, or join in any
institution against the Depositor 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 amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Noteholders under the Indenture at any time by the
Issuer with the consent of the Noteholders representing a majority of the
Outstanding Amount of all Notes at the time outstanding. The Indenture also
contains provisions permitting the Noteholders representing specified
percentages of the Outstanding Amount of the Notes, on behalf of all the
Noteholders, to waive compliance by the Issuer with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the holder of this Note (or any one of more
Predecessor Notes) shall be conclusive and binding upon such holder and upon all
future holders of this Note and of any Note issued upon registration of transfer
hereof or in exchange hereof or in lieu hereof whether or not notation of such
consent or waiver is made upon this Note. The Indenture also permits the
Indenture Trustee to amend or waive certain terms and conditions set forth in
the Indenture without the consent of holders of the Notes issued thereunder.

Noteholders under the Indenture.

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 The Bank of New York, in its individual
capacity, Chase Manhattan Bank USA, National Association 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 Eligible Lender Trustee in the assets of the Issuer. The Noteholder of this
Note by the acceptance hereof agrees that, except as expressly provided in the
Basic Documents, in the case of an Event of Default under the Indenture, the
Noteholder shall have no claim against any of the foregoing for any deficiency,

<Page>

                                [REVERSE OF NOTE]

          This Note is one of a duly authorized issue of Notes of the Issuer,
designated as its Floating Rate Class A-3 Student Loan-Backed Notes (the "Class
A-3 Notes"), which, together with the Issuer's Floating Rate Class A-1 Student
Loan-Backed Notes (the "Class A-1 Notes"), Floating Rate Class A-2 Student
Loan-Backed Notes (the "Class A-2 Notes"), Floating Rate Class A-4 Student
Loan-Backed Notes (the "Class A-4 Notes"), Reset Rate Class A-5A Student
Loan-Backed Notes (the "Class A-5A Notes"), Reset Rate Class A-5B Student
Loan-Backed Notes (the "Class A-5B Notes" and, together with the Class A-5A
Notes, the "Reset Rate Notes" and, the Reset Rate Notes together with the Class
A-1, Class A-2, Class A-3 and Class A-4 Notes, the "Class A Notes"), and
Floating Rate Class B Student Loan-Backed Notes (the "Class B Notes" and,
together with the Class A Notes, the "Notes"), are issued under and secured by
the Indenture, to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights and
obligations thereunder of the Issuer, the Indenture Trustee and the Noteholders.
The Notes are subject to all terms of the Indenture.

          The Class A-3 Notes are and will be equally and ratably secured by the
Collateral pledged as security therefor as provided in the Indenture. On any
Distribution Date, the Class A-1 Notes and the Class A-2 Notes are prior in
order of principal payment to the Class A-3 Notes, and the Class A-3 Notes are
prior in order of principal payment to the Class A-4 Notes, the Reset Rate Notes
and, up to the applicable Class A Noteholders' Principal Distribution Amount,
the Class B Notes. The Class A Notes are senior to the Class B Notes, as and to
the extent provided in the Indenture.

          Principal of the Class A-3 Notes shall be payable on each Distribution
Date in an amount described on the face hereof. "Distribution Date" means the
15th day of each March, June, September and December or, if any such date is not
a Business Day, the next succeeding Business Day, commencing September 2003.

          As described on the face hereof, the entire unpaid principal amount of
this Note shall be due and payable on the Class A-3 Maturity Date.
Notwithstanding the foregoing, the entire unpaid principal amount of the Notes
shall be due and payable on the date on which (i) an Event of Default shall have
occurred and be continuing and (ii) the Indenture Trustee or the Noteholders
representing not less than a majority of the Outstanding Amount of the Notes
shall have declared the Notes to be immediately due and payable in the manner
provided in Section 5.2 of the Indenture. All principal payments on the Class
A-3 Notes shall be made pro rata to the Noteholders entitled thereto.

          Interest on the Class A-3 Notes shall be payable on each Distribution
Date on the principal amount outstanding of the Class A-3 Notes until the
principal amount thereof is paid in full, at a rate per annum equal to the Class
A-3 Rate. The "Class A-3 Rate" for each Accrual Period, other than the initial
Accrual Period, shall be equal to Three-Month LIBOR as determined on the second
Business Day before the beginning of that Accrual Period plus 0.11%. For the
initial Accrual Period, the "Class A-3 Rate" shall be the Initial Accrual Rate
plus 0.11%.

          Payments of interest on this Note on each Distribution Date, together
with the installment of principal, if any, to the extent not in full payment of
this Note, shall be made by

                                  Exhibit A-20
<Page>

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

          The Issuer shall pay interest on overdue installments of interest on
this Note at the Class A-3 Rate to the extent lawful.

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

          Each Noteholder or Note Owner, by acceptance of a Note or, in the case
of a Note Owner, a beneficial interest in the Note, covenants and agrees that no
recourse may be taken, directly or indirectly, with respect to the obligations
of the Issuer or the Indenture Trustee on the Notes or under the Indenture or
any certificate or other writing delivered in connection therewith, against (i)
the Indenture Trustee or the Eligible Lender Trustee in its individual capacity,
(ii) any owner of a beneficial interest in the Issuer or (iii) any partner,
owner, beneficiary, agent, officer, director or employee of the Indenture
Trustee or the Eligible Lender Trustee in its individual

                                  Exhibit A-21
<Page>

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

          Upon acquisition or transfer of a beneficial interest in any
Book-Entry Note by, for or with the assets of, an employee benefit plan or other
retirement arrangement subject to Section 406 of ERISA or Section 4975 of the
Code, such Note Owner shall be deemed to have represented that such acquisition
or purchase will not constitute or otherwise result in a non-exempt prohibited
transaction in violation of Section 406 of ERISA or Section 4975 of the Code
which is not covered by a class or other applicable exemption. Any transfer
found to have been made in violation of such deemed representation shall be null
and void and of no effect.

          Each Noteholder or Note Owner, by acceptance of a Note or, in the case
of a Note Owner, a beneficial interest in a Note, covenants and agrees that by
accepting the benefits of the Indenture such Noteholder or Note Owner will not
at any time institute against the Depositor or the Issuer, or join in any
institution against the Depositor or the Issuer of, any bankruptcy,
reorganization, arrangement, insolvency, receivership or liquidation proceedings
or other proceedings under any United States Federal or state bankruptcy or
similar law in connection with any obligations relating to the Notes, the
Indenture or the other Basic Documents.

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

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

Noteholders under the Indenture.

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

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.

the times, place, and rate, and in the coin or currency, herein prescribed.

          Anything herein to the contrary notwithstanding, except as expressly

capacity, any owner of a beneficial interest in the Issuer, nor any of their
respective partners, beneficiaries, agents, officers, directors, employees or

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 Indenture. Interest on this Note shall accrue from and including the
preceding Distribution Date (or, in the case of the first Accrual Period, the

<Page>

                                [REVERSE OF NOTE]

          This Note is one of a duly authorized issue of Notes of the Issuer,
designated as its Floating Rate Class A-4 Student Loan-Backed Notes (the "Class
A-4 Notes"), which, together with the Issuer's Floating Rate Class A-1 Student
Loan-Backed Notes (the "Class A-1 Notes"), Floating Rate Class A-2 Student
Loan-Backed Notes (the "Class A-2 Notes"), Floating Rate Class A-3 Student
Loan-Backed Notes (the "Class A-3 Notes"), Reset Rate Class A-5A Student
Loan-Backed Notes (the "Class A-5A Notes"), Reset Rate Class A-5B Student
Loan-Backed Notes (the "Class A-5B Notes" and, together with the Class A-5A
Notes, the "Reset Rate Notes" and, the Reset Rate Notes together with the Class
A-1, Class A-2, Class A-3 and Class A-4 Notes, the "Class A Notes"), and
Floating Rate Class B Student Loan-Backed Notes (the "Class B Notes" and,
together with the Class A Notes, the "Notes"), are issued under and secured by
the Indenture, to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights and
obligations thereunder of the Issuer, the Indenture Trustee and the Noteholders.
The Notes are subject to all terms of the Indenture.

          The Class A-4 Notes are and will be equally and ratably secured by the
Collateral pledged as security therefor as provided in the Indenture. On any
Distribution Date, the Class A-1 Notes, Class A-2 Notes and Class A-3 Notes are
prior in order of principal payment to the Class A-4 Notes, and the Class A-4
Notes are prior in order of principal payment to the Reset Rate Notes and, up to
the applicable Class A Noteholders' Principal Distribution Amount. The Class A
Notes are senior to the Class B Notes, as and to the extent provided in the
Indenture.

          Principal of the Class A-4 Notes shall be payable on each Distribution
Date in an amount described on the face hereof. "Distribution Date" means the
15th day of each March, June, September and December or, if any such date is not
a Business Day, the next succeeding Business Day, commencing September 2003.

          As described on the face hereof, the entire unpaid principal amount of
this Note shall be due and payable on the Class A-4 Maturity Date.
Notwithstanding the foregoing, the entire unpaid principal amount of the Notes
shall be due and payable on the date on which (i) an Event of Default shall have
occurred and be continuing and (ii) the Indenture Trustee or the Noteholders
representing not less than a majority of the Outstanding Amount of the Notes
shall have declared the Notes to be immediately due and payable in the manner
provided in Section 5.2 of the Indenture. All principal payments on the Class
A-4 Notes shall be made pro rata to the Noteholders entitled thereto.

          Interest on the Class A-4 Notes shall be payable on each Distribution
Date on the principal amount outstanding of the Class A-4 Notes until the
principal amount thereof is paid in full, at a rate per annum equal to the Class
A-4 Rate. The "Class A-4 Rate" for each Accrual Period, other than the initial
Accrual Period, shall be equal to Three-Month LIBOR as determined on the second
Business Day before the beginning of that Accrual Period plus 0.20%. For the
initial Accrual Period, the "Class A-4 Rate" shall be the Initial Accrual Rate
plus 0.20%.

          Payments of interest on this Note on each Distribution Date, together
with the installment of principal, if any, to the extent not in full payment of
this Note, shall be made by check mailed to the Person whose name appears as the
Registered Holder of this Note (or one or

                                  Exhibit A-28
<Page>

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

          The Issuer shall pay interest on overdue installments of interest on
this Note at the Class A-4 Rate to the extent lawful.

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

          Each Noteholder or Note Owner, by acceptance of a Note or, in the case
of a Note Owner, a beneficial interest in the Note, covenants and agrees that no
recourse may be taken, directly or indirectly, with respect to the obligations
of the Issuer or the Indenture Trustee on the Notes or under the Indenture or
any certificate or other writing delivered in connection therewith, against (i)
the Indenture Trustee or the Eligible Lender Trustee in its individual capacity,
(ii) any owner of a beneficial interest in the Issuer or (iii) any partner,
owner, beneficiary, agent, officer, director or employee of the Indenture
Trustee or the Eligible Lender Trustee in its individual capacity, any holder or
owner of a beneficial interest in the Issuer, the Eligible Lender Trustee or

                                  Exhibit A-29
<Page>

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

          Upon acquisition or transfer of a beneficial interest in any
Book-Entry Note by, for or with the assets of, an employee benefit plan or other
retirement arrangement subject to Section 406 of ERISA or Section 4975 of the
Code, such Note Owner shall be deemed to have represented that such acquisition
or purchase will not constitute or otherwise result in a non-exempt prohibited
transaction in violation of Section 406 of ERISA or Section 4975 of the Code
which is not covered by a class or other applicable exemption. Any transfer
found to have been made in violation of such deemed representation shall be null
and void and of no effect.

          Each Noteholder or Note Owner, by acceptance of a Note or, in the case
of a Note Owner, a beneficial interest in a Note, covenants and agrees that by
accepting the benefits of the Indenture such Noteholder or Note Owner will not
at any time institute against the Depositor or the Issuer, or join in any
institution against the Depositor or the Issuer of, any bankruptcy,
reorganization, arrangement, insolvency, receivership or liquidation proceedings
or other proceedings under any United States Federal or state bankruptcy or
similar law in connection with any obligations relating to the Notes, the
Indenture or the other Basic Documents.

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

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

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

                                  Exhibit A-30
<Page>

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

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

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

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

          Anything herein to the contrary notwithstanding, except as expressly
provided in the Basic Documents, neither The Bank of New York, in its individual
capacity, Chase Manhattan Bank USA, National Association in its individual
capacity, any owner of a beneficial interest in the Issuer, nor any of their
respective partners, beneficiaries, agents, officers, directors, employees or
successors or assigns shall be personally liable for, nor shall recourse be had
to any of them for, the payment of principal of or interest on, or performance
of, or omission to perform, any of the covenants, obligations or
indemnifications contained in this Note or the Indenture; it being expressly
understood that said covenants, obligations and indemnifications have been made
by the Eligible Lender Trustee for the sole purposes of binding the interests of
the Eligible Lender Trustee in the assets of the Issuer. The Noteholder of this
Note by the acceptance hereof agrees that, except as expressly provided in the
Basic Documents, in the case of an Event of Default under the Indenture, the
Noteholder shall have no claim against any of the foregoing for any deficiency,
loss or claim therefrom; PROVIDED, HOWEVER, that nothing contained herein shall
be taken to prevent recourse to, and enforcement against, the assets of the
Issuer for any and all liabilities, obligations and undertakings contained in

Distribution Date in an amount equal to the result obtained by multiplying (i) a
fraction the numerator of which is $75,985,000 and the denominator of which is

Distribution Date), subject to certain limitations contained in Section 3.1 of
the Indenture. Interest on this Note shall accrue from and including the
preceding Distribution Date (or, in the case of the first Accrual Period, the
Closing Date) to but excluding the following Distribution Date (each an "Accrual

elapsed in each Accrual Period divided by 360. Such principal of and interest on
this Note shall be paid in the manner specified on the reverse hereof.

with respect to this Note shall be applied first to interest due and payable on
this Note as provided above and then to the unpaid principal of this Note.

          Reference is made to the further provisions of this Note set forth on
the reverse hereof, which shall have the same effect as though fully set forth
on the face of this Note.

          Unless the certificate of authentication hereon has been executed by
the Indenture Trustee whose name appears below by manual signature, this Note
shall not be entitled to any benefit under the Indenture referred to on the
reverse hereof, or be valid or obligatory for any purpose.

<Page>

                                [REVERSE OF NOTE]

          This Note is one of a duly authorized issue of Notes of the Issuer,
designated as its Floating Rate Class B Student Loan-Backed Notes (the "Class B
Notes"), which, together with the Issuer's Floating Rate Class A-1 Student
Loan-Backed Notes (the "Class A-1 Notes"), Floating Rate Class A-2 Student
Loan-Backed Notes (the "Class A-2 Notes"), Floating Rate Class A-3 Student
Loan-Backed Notes (the "Class A-3 Notes") and the Issuer's Floating Rate Class
A-4 Student Loan-Backed Notes (the "Class A-4 Notes"), Reset Rate Class A-5A
Student Loan-Backed Notes (the "Class A-5A Notes"), Reset Rate Class A-5B
Student Loan-Backed Notes (the "Class A-5B Notes" and, together with the Class
A-5A Notes, the "Reset Rate Notes" and, the Reset Rate Notes together with the
Class A-1, Class A-2, Class A-3 and Class A-4 Notes, the "Class A Notes" and,
the Class A Notes together with the Class B Notes, the "Notes"), are issued
under and secured by the Indenture, to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights and obligations thereunder of the Issuer, the Indenture Trustee and the
Noteholders. The Notes are subject to all terms of the Indenture.

          The Class B Notes are and will be equally and ratably secured by the
Collateral pledged as security therefor as provided in the Indenture. On any
Distribution Date, the Class A Notes are prior in order of principal payment to
the Class B Notes, up to the applicable Class A Noteholders' Principal
Distribution Amount. The Class B Notes are subordinate to the Class A Notes as
and to the extent provided in the Indenture.

          Principal of the Class B Notes shall be payable on each Distribution
Date in an amount described on the face hereof. "Distribution Date" means the
15th day of each March, June, September and December or, if any such date is not
a Business Day, the next succeeding Business Day, commencing September 2003.

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

          Interest on the Class B Notes shall be payable on each Distribution
Date on the principal amount outstanding of the Class B Notes until the
principal amount thereof is paid in full, at a rate per annum equal to the Class
B Rate. The "Class B Rate" for each Accrual Period, other than the initial
Accrual Period, shall be equal to Three-Month LIBOR as determined on the second
Business Day before the beginning of that Accrual Period plus 0.57%. For the
initial Accrual Period, the "Class B Rate" shall be the Initial Accrual Rate
plus 0.57%.

          Payments of interest on this Note on each Distribution Date, together
with the installment of principal, if any, to the extent not in full payment of
this Note, shall be made by check mailed to the Person whose name appears as the
Registered Holder of this Note (or one or

                                  Exhibit A-36
<Page>

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

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

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

          Each Noteholder or Note Owner, by acceptance of a Note or, in the case
of a Note Owner, a beneficial interest in the Note, covenants and agrees that no
recourse may be taken, directly or indirectly, with respect to the obligations
of the Issuer or the Indenture Trustee on the Notes or under the Indenture or
any certificate or other writing delivered in connection therewith, against (i)
the Indenture Trustee or the Eligible Lender Trustee in its individual capacity,
(ii) any owner of a beneficial interest in the Issuer or (iii) any partner,
owner, beneficiary, agent, officer, director or employee of the Indenture
Trustee or the Eligible Lender Trustee in its individual capacity, any holder or
owner of a beneficial interest in the Issuer, the Eligible Lender Trustee or

                                  Exhibit A-37
<Page>

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

          Upon acquisition or transfer of a beneficial interest in any
Book-Entry Note by, for or with the assets of, an employee benefit plan or other
retirement arrangement subject to Section 406 of ERISA or Section 4975 of the
Code, such Note Owner shall be deemed to have represented that such acquisition
or purchase will not constitute or otherwise result in a non-exempt prohibited
transaction in violation of Section 406 of ERISA or Section 4975 of the Code
which is not covered by a class or other applicable exemption. Any transfer
found to have been made in violation of such deemed representation shall be null
and void and of no effect.

          Each Noteholder or Note Owner, by acceptance of a Note or, in the case
of a Note Owner, a beneficial interest in a Note, covenants and agrees that by
accepting the benefits of the Indenture such Noteholder or Note Owner will not
at any time institute against the Depositor or the Issuer, or join in any
institution against the Depositor or the Issuer of, any bankruptcy,
reorganization, arrangement, insolvency, receivership or liquidation proceedings
or other proceedings under any United States Federal or state bankruptcy or
similar law in connection with any obligations relating to the Notes, the
Indenture or the other Basic Documents.

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

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

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

                                  Exhibit A-38
<Page>

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

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

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

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

          Anything herein to the contrary notwithstanding, except as expressly
provided in the Basic Documents, neither The Bank of New York, in its individual
capacity, Chase Manhattan Bank USA, National Association in its individual
capacity, any owner of a beneficial interest in the Issuer, nor any of their
respective partners, beneficiaries, agents, officers, directors, employees or
successors or assigns shall be personally liable for, nor shall recourse be had
to any of them for, the payment of principal of or interest on, or performance
of, or omission to perform, any of the covenants, obligations or
indemnifications contained in this Note or the Indenture; it being expressly
understood that said covenants, obligations and indemnifications have been made
by the Eligible Lender Trustee for the sole purposes of binding the interests of
the Eligible Lender Trustee in the assets of the Issuer. The Noteholder of this
Note by the acceptance hereof agrees that, except as expressly provided in the
Basic Documents, in the case of an Event of Default under the Indenture, the
Noteholder shall have no claim against any of the foregoing for any deficiency,
loss or claim therefrom; PROVIDED, HOWEVER, that nothing contained herein shall
be taken to prevent recourse to, and enforcement against, the assets of the
Issuer for any and all liabilities, obligations and undertakings contained in
the Indenture or in this Note.
