                   SUCCESSOR INTERIM ELIGIBLE LENDER TRUSTEES

         SECTION 8.1 ELIGIBILITY REQUIREMENTS FOR INTERIM ELIGIBLE LENDER
TRUSTEE. The Interim Eligible Lender Trustee shall at all times be a corporation
or banking association (i) qualifying as an "eligible lender" as such term is
defined in Section 435(d) of the Higher Education Act for purposes of holding
legal title to the Interim Trust Loans on behalf and for the benefit of the
Depositor, with a valid lender identification number with respect to the Interim
Trust Loans from the Department; and (ii) being authorized to exercise corporate
trust powers and hold legal title to the Interim Trust Loans. In case at any
time the Interim Eligible Lender Trustee shall cease to be eligible in
accordance with the provisions of this Section, the Interim Eligible Lender
Trustee shall resign immediately in the manner and with the effect specified in
Section 8.2.

         SECTION 8.2 RESIGNATION OR REMOVAL OF INTERIM ELIGIBLE LENDER TRUSTEE.
The Interim Eligible Lender Trustee may at any time resign and be discharged
from the trust hereby created by giving written notice thereof to the Depositor.
Upon receiving such notice of resignation, the Depositor shall promptly appoint
a successor Interim Eligible Lender Trustee meeting the eligibility requirements
of Section 8.1 by written instrument, in duplicate, one copy of which instrument
shall be delivered to the resigning Interim Eligible Lender Trustee and one copy
to the successor Interim Eligible Lender Trustee. If no successor Interim
Eligible Lender Trustee shall have been so appointed and have accepted
appointment within 30 days after the giving of such notice of resignation, the
resigning Interim Eligible Lender Trustee may petition any court of competent
jurisdiction for the appointment of a successor Interim Eligible Lender Trustee;
provided, however, that such right to appoint or to petition for the appointment
of any such successor shall in no event relieve the resigning Interim Eligible
Lender Trustee from any obligations otherwise imposed on it under this
Agreement, the Purchase Agreement or the Sale Agreement until such successor has
in fact assumed such appointment.

         If at any time the Interim Eligible Lender Trustee shall cease to be or
shall be likely to cease to be eligible in accordance with the provisions of
Section 8.1 and shall fail to resign after written request therefor by the
Depositor, then the Depositor may remove the Interim Eligible Lender Trustee. If
the Depositor shall remove the Interim Eligible Lender Trustee under the
authority of the immediately preceding sentence, the Depositor shall promptly
appoint a

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

         Any resignation or removal of the Interim Eligible Lender Trustee and
appointment of a successor Interim Eligible Lender Trustee pursuant to any of
the provisions of this Section shall not become effective until acceptance of
appointment by the successor Interim Eligible Lender Trustee pursuant to Section
8.3 and payment of all fees and expenses owed to the outgoing Interim Eligible
Lender Trustee.

         SECTION 8.3 SUCCESSOR INTERIM ELIGIBLE LENDER TRUSTEE. Any successor
Interim Eligible Lender Trustee appointed pursuant to Section 8.2 shall execute,
acknowledge and deliver to the Depositor and to its predecessor Interim Eligible
Lender Trustee an instrument accepting such appointment under this Agreement,
and thereupon the resignation or removal of the predecessor Interim Eligible
Lender Trustee shall become effective and such successor Interim Eligible Lender
Trustee, without any further act, deed or conveyance, shall become fully vested
with all the rights, powers, duties and obligations of its predecessor under
this Agreement, with like effect as if originally named as Interim Eligible
Lender Trustee. The predecessor Interim Eligible Lender Trustee shall upon
payment of its fees and expenses deliver to the successor Interim Eligible
Lender Trustee all documents, statements, moneys and properties held by it under
this Agreement and shall assign, if permissible, to the successor Interim
Eligible Lender Trustee any lender identification number obtained from the
Department with respect to the Interim Trust Loans; and the Depositor and the
predecessor Interim Eligible Lender Trustee shall execute and deliver such
instruments and do such other things as may reasonably be required for fully and
certainly vesting and confirming in the successor Interim Eligible Lender
Trustee all such rights, powers, duties and obligations.

         No successor Interim Eligible Lender Trustee shall accept such
appointment as provided in this Section unless at the time of such acceptance
such successor Interim Eligible Lender Trustee shall be eligible pursuant to
Section 8.1.

         SECTION 8.4 MERGER OR CONSOLIDATION OF INTERIM ELIGIBLE LENDER TRUSTEE.
Any corporation into which the Interim Eligible Lender Trustee may be merged or
converted or with which it may be consolidated, or any corporation or banking
association resulting from any merger, conversion or consolidation to which the
Interim Eligible Lender Trustee shall be a party, or any corporation succeeding
to all or substantially all the corporate trust business of the Interim Eligible
Lender Trustee, shall, without the execution or filing of any instrument or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding, be the successor of the Interim Eligible Lender
Trustee hereunder; provided that such corporation or banking association shall
be eligible pursuant to Section 8.1.

Interim Eligible Lender Trustee shall furnish written notification of the
substance of such amendment or consent to the Indenture Trustee and each of the

                                    The Notes

                  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
portion of the text of any Note may be set forth on the reverse thereof, with an
appropriate reference thereto on the face of the Note.

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

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

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

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

                  The Indenture Trustee shall upon Issuer Order authenticate and
deliver Notes for original issue in an aggregate principal amount of
$1,520,751,000. The aggregate principal amount of Notes outstanding at any time

<PAGE>

                  Each Note shall be dated the date of its authentication. The
Class A Notes shall be issuable as registered Class A Notes in the minimum
denomination of $1,000 and in integral multiples of $1,000 in excess thereof.
The Class B Notes shall be issuable as registered Class B Notes in the minimum
denomination of $100,000 and in integral multiples of $1,000 in excess thereof.

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

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

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

                  SECTION 2.4 Registration; Registration of Transfer and
Exchange. The Issuer shall cause to be kept a register (the "Note Register") in

14.1 Indenture

                                       5
<PAGE>

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, if
the requirements of Section 8-401(1) of the UCC are met, the Issuer shall
execute, and the Indenture Trustee shall authenticate and the Noteholder shall
obtain from the Indenture Trustee, in the name of the designated transferee or
transferees, one or more new Notes in any authorized denominations and a like
aggregate principal amount.

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

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

14.1 Indenture

                                       6
<PAGE>

                  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 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

14.1 Indenture

                                       7
<PAGE>

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

14.1 Indenture

                                       8
<PAGE>

Note and for all other purposes whatsoever, whether or not such Note be overdue,
and neither the Issuer, the Indenture Trustee nor any agent of the Issuer or the
Indenture Trustee shall be affected by notice to the contrary.

                  SECTION 2.7 Payment of Principal and Interest; Note Interest
Shortfall. (a) The Notes shall accrue interest as provided in the forms of Notes
set forth in Exhibit A, and such interest shall be payable on each Distribution
Date as specified therein, subject to Section 3.1. Any installment of interest
or principal, if any, payable on any Note which is punctually paid or duly
provided for by the Issuer on the applicable Distribution Date shall be paid to
the Person in whose name such Note (or one or more Predecessor Notes) is
registered on the Record Date by check mailed first-class, postage prepaid to
such Person's address as it appears on 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.),
payment shall be made by wire transfer in immediately available funds to the
account designated by such nominee and except for the final installment of
principal payable with respect to such Note on a Distribution Date or on the
Note Final Maturity Date for such Note which shall be payable as provided below.
The funds represented by any such checks returned undelivered shall be held in
accordance with Section 3.3.

         (b)      The principal of each Note shall be payable in installments on
each Distribution Date as provided in the forms of Note set forth in Exhibit A.
Notwithstanding the foregoing, the entire unpaid principal amount of each class
of the Notes shall be due and payable, if not previously paid, on the Note Final
Maturity Date for such class of Notes and on the date on which an Event of
Default shall have occurred and be continuing if the Indenture Trustee or the
Noteholders of the Notes representing not less than a majority of the
Outstanding Amount of the Notes have declared the Notes to be immediately due
and payable in the manner provided in Section 5.2. All principal payments on the
Notes shall be made pro rata to the 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

14.1 Indenture

                                       9
<PAGE>

prior to such final Distribution Date and shall specify that such final
installment will be payable only upon presentation and surrender of such Note
and shall specify the place where such Note may be presented and surrendered for
payment of such installment. Notices in connection with redemptions of Notes
shall be mailed to Noteholders as provided in Section 10.2.

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

                  SECTION 2.8 Cancellation. All Notes surrendered for payment,
registration of transfer, exchange or redemption shall, if surrendered to any
Person other than the Indenture Trustee, be delivered to the Indenture Trustee
and shall be promptly cancelled by the Indenture Trustee. The Issuer may at any
time deliver to the Indenture Trustee for cancellation any Notes previously
authenticated and delivered hereunder which the Issuer may have acquired in any
manner whatsoever and all Notes so delivered shall be promptly cancelled by the
Indenture Trustee. No Notes shall be authenticated in lieu of or in exchange for
any Notes cancelled as provided in this Section, except as expressly permitted
by this Indenture. All canceled Notes may be held or disposed of by the
Indenture Trustee in accordance with its standard retention or disposal policy
as in effect at the time, unless the Issuer shall direct by an Issuer Order that
they be returned to it and so long as such Issuer Order is timely and the Notes
have not been previously disposed of by the Indenture Trustee.

                  SECTION 2.9 Release of Collateral. Subject to Section 11.1 and
the terms of the Basic Documents, the Indenture Trustee shall release property
from the lien of this Indenture only upon receipt of an Issuer Request
accompanied by an Officers' Certificate of the Issuer, an Opinion of Counsel and
Independent Certificates in accordance with TIA 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 Depository Trust Company, as the
initial Clearing Agency, by, or on behalf of, the Issuer. Such Notes shall
initially be registered on

14.1 Indenture

                                       10
<PAGE>

the Note Register in the name of Cede & Co., the nominee of the initial Clearing
Agency, and no Note Owner shall receive a Definitive Note (as defined below)
representing such Note Owner's interest in such Note, except as provided in
Section 2.12. Unless and until definitive, fully registered Notes (the
"Definitive Notes") have been issued to Note Owners pursuant to Section 2.12:

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

                  (ii) the Note Registrar and the Indenture Trustee, and their
respective directors, officers, employees and agents, may deal with the
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 Agreement; and unless and until Definitive Notes are issued pursuant
to Section 2.12, the initial Clearing Agency will make book-entry transfers
among the 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; and

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

14.1 Indenture

<PAGE>

                  (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 ("Plan"), such Note Owner shall be deemed to have
represented that such acquisition or purchase will not constitute or otherwise
result in: (i) in the case of a Plan subject to Section 406 of ERISA or Section
4975 of the Code, a non-exempt prohibited transaction in violation of Section
406 of ERISA or Section 4975 of the Code which is not coved by a class or other
applicable exemption and (ii) in the case of a Plan subject to a substantially
similar federal, state, local or foreign law ("Similar Law"), a non-exempt
violation of such substantially Similar Law. 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
communications 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 is no longer
willing or able to discharge its responsibilities with respect to the Notes, and
the Administrator is unable to locate a successor, (ii) the Administrator at its
option advises the Indenture Trustee in writing that it elects to terminate the
book-entry system through 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 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 the 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

14.1 Indenture

                                       12
<PAGE>

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

                  Upon acquisition or transfer a Definitive Note by, for or with
the assets of, an employee benefit plan or other retirement arrangement
("Plan"), such Note Owner shall be deemed to have represented that such
acquisition or purchase will not constitute or otherwise result in: (i) in the
case of a Plan subject to Section 406 of ERISA or Section 4975 of the Code, a
non-exempt prohibited transaction in violation of Section 406 of ERISA or
Section 4975 of the Code which is not coved by a class or other applicable
exemption and (ii) in the case of a Plan subject to a substantially similar
federal, state, local or foreign law ("Similar Law"), a non-exempt violation of
such substantially Similar Law. Any transfer found to have been made in
violation of such deemed representation shall be null and void and of no effect.

                                    Covenants

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

<PAGE>

                  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 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 shall be paid over to the Issuer
except as provided in this Section.

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

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

<PAGE>

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

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

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

                  (iv)     immediately resign as a Paying Agent and forthwith
pay to the Indenture Trustee all sums held by it in trust for the payment of
Notes if at any time it ceases to meet the standards required to be met by a
Paying Agent at the time of its appointment; and

                  (v)      comply with all requirements of the Code with respect
to the withholding from any payments made by it on any Notes of any applicable
withholding taxes imposed 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

14.1 Indenture

                                       15
<PAGE>

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

                  SECTION 3.4 Existence. The Issuer shall keep in full effect
its existence, rights and franchises as a 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:

14.1 Indenture

                                       16
<PAGE>

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

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

                  (iii)    enforce any of the Collateral; or

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

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

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

<PAGE>

                  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

14.1 Indenture

                                       18
<PAGE>

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

         (e)      As promptly as possible after the giving of notice of
termination to the Servicer of the Servicer's rights and powers, pursuant to
Section 5.1 of the Servicing Agreement, or to the Administrator of the
Administrator's rights and powers, pursuant to Section 5.1 of the Administration
Agreement, the Issuer shall appoint a successor servicer (the "Successor
Servicer") or a successor administrator (the "Successor Administrator"),
respectively, and such Successor Servicer or Successor Administrator, as the
case may be, shall accept its appointment by a written assumption in a form
acceptable to the Indenture Trustee. In the event that a Successor Servicer or
Successor Administrator has not been appointed and accepted its appointment at
the time when the Servicer or Administrator, as the case may be, ceases to act
as Servicer or Administrator, respectively, the Indenture Trustee without
further action shall automatically be appointed the Successor Servicer or
Successor Administrator, as the case may be. The Indenture Trustee may resign as
the 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

14.1 Indenture

                                       19
<PAGE>

(B) whose regular business includes the servicing or administration of student
loans and (ii) enter into a servicing agreement or an administration agreement,
respectively, with the Issuer having substantially the same provisions as the
provisions of the Servicing Agreement and the Administration Agreement, as
applicable. If within 30 days after the delivery of the notice referred to
above, the Issuer shall not have obtained such a new servicer or new
administrator, as the case may be, the Indenture Trustee may appoint, or may
petition a court of competent jurisdiction to appoint, a Successor Servicer or
Successor Administrator; provided, however, that such right to appoint or to
petition for the appointment of any such successor shall in no event relieve the
Indenture Trustee from any obligations otherwise imposed on it under the Basic
Documents until such successor has in fact assumed such appointment. In
connection with any such appointment, the Indenture Trustee may make such
arrangements for the compensation of such successor as it and such successor
shall agree, subject to the limitations set forth below and in the Servicing
Agreement or Administration Agreement, as applicable, and in accordance with
Section 5.2 of the Servicing Agreement and Section 5.2 of the Administration
Agreement, the Issuer shall enter into an agreement with such successor for the
servicing or administration of the Trust Student Loans (such agreement to be in
form and substance satisfactory to the Indenture Trustee). If the Indenture
Trustee shall succeed as provided herein to the Servicer's duties as Servicer
with respect to the Trust Student Loans, or the Administrator's duties with
respect to the Issuer and the Trust Student Loans, as the case may be, it shall
do so in its individual capacity and not in its capacity as Indenture Trustee
and, accordingly, the provisions of Article VI hereof shall be inapplicable to
the Indenture Trustee in its duties as the successor to the Servicer or the
Administrator, as the case may be, and the servicing or administration of the
Trust Student Loans. In case the Indenture Trustee shall become successor to the
Servicer or the Administrator, the Indenture Trustee shall be entitled to
appoint as Servicer or as Administrator, as the case may be, any one of its
Affiliates, provided that such appointment shall not affect or alter in any way
the liability of the Indenture Trustee as Successor Servicer or Successor
Administrator, respectively, in accordance with the terms hereof.

         (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

14.1 Indenture

                                       20
<PAGE>

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 under the Basic
Documents; provided, however, that no such amendment shall (i) increase or
reduce in any manner the amount of, or accelerate or delay the timing of,
distributions that are required to be made for the benefit of the Noteholders,
or (ii) reduce the aforesaid percentage of the Notes which are required to
consent to any such amendment, without the consent of the Noteholders of all the
Outstanding Notes. If any such amendment, modification, supplement or waiver
shall be so consented to by the Indenture Trustee or such Noteholders, the
Issuer shall give written notice thereof to each Rating Agency and agrees,
promptly following a request by the Indenture Trustee to do so, to execute and
deliver, in its own name and at its own expense, such agreements, instruments,
consents and other documents as the Indenture Trustee may deem necessary or
appropriate in the circumstances.

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

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

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

14.1 Indenture

                                       21
<PAGE>

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

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

                  (iv)     enter into any amendment to the Interest Rate Cap
Agreement to cure any ambiguity in, or to correct or supplement any provision of
the Interest Rate Cap 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 Issuer 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

14.1 Indenture

<PAGE>

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

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

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

                  (i)      the Person (if other than the Issuer) formed by or

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

the properties and assets of the Issuer the conveyance or transfer of which is
hereby restricted shall (A) be a United States citizen or a Person organized and
existing under the laws of the United States of America or any State, (B)
expressly assume, by an indenture supplemental hereto, executed and delivered to

Indenture Trustee, the Issuer will execute and deliver such further instruments
and do such further acts as may be reasonably necessary or proper to carry out
more effectively the purpose of this Indenture.

within one year under arrangements satisfactory to the Indenture Trustee for the

                  (b)      the Issuer has paid or caused to be paid all other

Officers' Certificate of the Issuer, an Opinion of Counsel and (if required by
the TIA or the Indenture Trustee) an Independent Certificate from a firm of
certified public accountants, each meeting the applicable requirements of
Section 11.1(a) and, subject to Section 11.2, each stating that all conditions
precedent herein

14.1 Indenture

                                       28
<PAGE>

provided for relating to the satisfaction and discharge of this Indenture have
been complied with.

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

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

                  SECTION 4.4 Auction of Trust Student Loans. Any Trust Student
Loans remaining in the Trust as of the end of the Collection Period immediately
preceding the earliest Distribution Date on which the Pool Balance is equal to
10% or less of the initial Pool Balance three Business Days prior to such
Distribution Date (the "Trust Auction Date") shall be offered for sale by the
Indenture Trustee unless the 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

14.1 Indenture

                                       29
<PAGE>

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
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 6.1 of the Administration Agreement with respect to each such future
Distribution Date.

                                       30

<PAGE>

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

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

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

                  (v)      the commencement by the Issuer of a voluntary case
under any applicable Federal or state bankruptcy, insolvency or other similar
law now or hereafter in effect, or the consent by the Issuer to the entry of an
order for relief in an involuntary case under any such law, or the consent by
the Issuer to the appointment or taking possession by a receiver, liquidator,
assignee, custodian, trustee, sequestrator or similar official of the Issuer or
for any substantial part of the Indenture Trust Estate, or the making by the
Issuer of any general assignment

14.1 Indenture

                                       31

<PAGE>

for the benefit of creditors, or the failure by the Issuer generally to pay its
debts as such debts become due, or the taking of action by the Issuer in
furtherance of any of the foregoing.

                  SECTION 5.2 Acceleration of Maturity; Rescission and
Annulment. If an Event of Default should occur and be continuing, then and in
every such case the Indenture Trustee or the Noteholders 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.

14.1 Indenture

<PAGE>

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

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

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

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

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

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

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

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

                  (iv)     to file such proofs of claim and other papers or
         documents as may be necessary or advisable in order to have the claims
         of the

14.1 Indenture

                                       34

<PAGE>

         Indenture Trustee, any Swap Counterparty or the Noteholders allowed in
         any judicial proceedings relative to the Issuer, its creditors and its
         property;

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

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

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

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

<PAGE>

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

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

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

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

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

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

provided, however, that the Indenture Trustee may not sell or otherwise
liquidate the Indenture Trust Estate following an Event of Default, other than
an Event of Default described in Section 5.1(i) or (ii) 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

14.1 Indenture

                                       36

<PAGE>

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 the Trust Account) 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:

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

                  SECOND: to the Servicer for due and unpaid Primary Servicing

<PAGE>
                  THIRD: to the Administrator, any due and unpaid Administration
Fees;

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

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

                  SIXTH: to the Class B Noteholders for amounts due and unpaid
on the Class B Notes for interest;

                  SEVENTH: to the Class B Noteholders for amounts due and unpaid
on the Class B Notes for principal;

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

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

                  TENTH: to the Swap Counterparty, the amount of any termination
payment due to the Swap Counterparty by the Issuer under the Interest Rate Cap
Agreement.

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

                  SECTION 5.5 Optional Preservation of the Trust Student Loans.
If the Notes have been declared to be due and payable under Section 5.2

14.1 Indenture

                                       38

<PAGE>

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

                  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;

14.1 Indenture

                                       39

<PAGE>

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

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

                  SECTION 5.7 Unconditional Rights of Noteholders To Receive
Principal and Interest. Notwithstanding any other provisions in this Indenture,
any Noteholder shall have the right, which is absolute and unconditional, to
receive payment of the principal of and interest on such Note on or after the
respective due dates thereof expressed in such Note or in this Indenture (or, in
the case of redemption, on or after the Redemption Date) and to institute suit
for the enforcement of any such payment, and such right shall not be impaired
without the consent of such Noteholder.

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

                  SECTION 5.9 Rights and Remedies Cumulative. No right or remedy
herein conferred upon or reserved to the Indenture Trustee or to the Noteholders
is intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter

14.1 Indenture

                                       40

<PAGE>

existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

                  SECTION 5.10 Delay or Omission Not a Waiver. No delay or
omission of the Indenture Trustee or any Noteholder to exercise any right or
remedy accruing upon any Default shall impair any such right or remedy or
constitute a waiver of any such Default or an acquiescence therein. Every right
and remedy given by this Article V or by law to the Indenture Trustee, 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 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;

14.1 Indenture

                                       41

<PAGE>

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).

14.1 Indenture

<PAGE>

                  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

14.1 Indenture

                                       43

<PAGE>

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

14.1 Indenture

                                       44

<PAGE>

covenants or obligations shall be read into this Indenture against the Indenture
Trustee; and

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

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

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

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

                  (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

14.1 Indenture

                                       45

<PAGE>

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 presented by the proper Person. The Indenture Trustee need not
investigate any fact or matter stated in such document.

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

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

         (d)      The Indenture Trustee shall not be liable for any action it
takes or omits to take in good faith which it believes to be authorized or
within its rights or

14.1 Indenture

                                       46

<PAGE>

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

14.1 Indenture

                                       47

<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

14.1 Indenture

                                       48

<PAGE>

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 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.

14.1 Indenture

                                       49

<PAGE>

                  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.

                  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

14.1 Indenture

                                       50

<PAGE>

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

14.1 Indenture

                                       51

<PAGE>

unqualified to perform such act or acts, in which event such rights, powers,
duties and obligations (including the holding of title to the Indenture Trust
Estate or any portion thereof in any such jurisdiction) shall be exercised and
performed singly by such separate trustee or co-trustee, but solely at the
direction of the Indenture Trustee;

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

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

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

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

                  SECTION 6.11 Eligibility; Disqualification. The Indenture
Trustee shall at all times satisfy the requirements of TIA Section 310(a), the
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

indicated.

                                   ARTICLE VII

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

                  SECTION 7.2 Preservation of Information; Communications to
Noteholders. The Indenture Trustee shall preserve, in as current a form as is
reasonably practicable, the names and addresses of the Noteholders contained in
the most recent list furnished to the Indenture Trustee as provided in Section

furnished.

         (a)      Noteholders may communicate pursuant to TIA Section 312(b)

of Noteholders (whether or not made pursuant to TIA Section 312(b)), the
Indenture Trustee shall promptly notify the Administrator thereof by providing
to the Administrator a copy of such request and a copy of the list of
Noteholders produced in response thereto.

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

to each Noteholder of record as of the related Record Date the information

other instruments furnished to the Indenture Trustee under the Basic Documents.
The Indenture Trustee shall furnish to the Noteholders promptly upon receipt

                                  ARTICLE VIII

                      Accounts, Disbursements and Releases

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

                  SECTION 8.2 Trust Accounts. (a) On or prior to the Closing

name of the Indenture Trustee, for the benefit of the Noteholders, the Trust
Accounts as provided in Section 2.3(a) of the Administration Agreement.

                           (b)      On or before the Business Day preceding each
Distribution Date, all Available Funds with respect to the preceding Collection
Period will be deposited in the Collection Account as provided in Section 2.4 of
the Administration Agreement. On or before each Distribution Date, the Indenture
Trustee (or any other Paying Agent) shall make the deposits and distributions as
provided in Sections 2.7, 2.8 and 2.9 of the Administration Agreement.

                  SECTION 8.3 General Provisions Regarding Accounts. (a) So long
as no Default shall have occurred and be continuing, all or a portion of the
funds in the Trust Accounts shall be invested in Eligible Investments and
reinvested by the Indenture Trustee upon Issuer Order, subject to the provisions
of Section 2.3(b) of the Administration Agreement. All income or other gain from
investments of moneys deposited in the Trust Accounts shall be deposited by the
Indenture Trustee in the Collection Account, and any loss resulting from such
investments shall be charged to such Trust Account. 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 will not direct the Indenture Trustee
to make any investment of any funds or to sell any investment held in any of the
Trust Accounts unless the security interest granted and perfected in such
account will continue to be perfected in such investment or the proceeds of such
sale, in either case without any further action by any Person, and, in
connection with any direction to the Indenture Trustee to make any such
investment or sale, if requested by the Indenture Trustee, the Issuer shall
deliver to the Indenture Trustee an Opinion of Counsel, acceptable to the
Indenture Trustee, to such effect.

         (b)      Subject to Section 6.1(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

14.1 Indenture

                                       56

<PAGE>

Indenture Trustee, in its commercial capacity as principal obligor and not as
trustee, in accordance with their terms.

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

                  SECTION 8.4 Release of Indenture Trust Estate. (a) Subject to
the payment of its fees and expenses pursuant to Section 6.7, the Indenture
Trustee may, and when required by the provisions of this Indenture shall,
execute instruments to release property from the lien of this Indenture, or
convey the Indenture Trustee's interest in the same, in a manner and under
circumstances that are not inconsistent with the provisions of this Indenture.
No party relying upon an instrument executed by the Indenture Trustee as
provided in this Article VIII shall be bound to ascertain the Indenture
Trustee's authority, inquire into the satisfaction of any conditions precedent
or see to the application of any moneys.

         (b)      The Indenture Trustee shall, at such time as there are no
Notes Outstanding and all sums due the Indenture Trustee pursuant to Section 6.7
have been paid, release any remaining portion of the Indenture Trust Estate that
secured the Notes from the lien of this Indenture and release to the Issuer or
any other Person entitled thereto any funds then on deposit in the Trust
Accounts. The Indenture Trustee shall release property from the lien of this
Indenture pursuant to this Section 8.4(b) only upon receipt of an Issuer Request
accompanied by an Officers' Certificate of the Issuer, an Opinion of Counsel and
(if required by the TIA) Independent Certificates in accordance with TIA
Sections 314(c) and 314(d)(1) meeting the applicable requirements of Section
11.1.

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

                  SECTION 8.5 Opinion of Counsel. The Indenture Trustee shall
receive at least seven days' notice when requested by the Issuer to take any
action pursuant to Section 8.4(a), accompanied by copies of any instruments
involved, and the Indenture Trustee shall also require, except in connection
with any action contemplated by Section 8.4(c), as a condition to such action,
an Opinion of Counsel, in form and substance satisfactory to the Indenture
Trustee, stating the legal effect of any such action, outlining the steps
required to complete the same, and concluding that all conditions precedent to
the taking of such action have been complied with and such action will not
materially and adversely impair the security for the Notes or the rights of the
Noteholders in contravention of the provisions of this Indenture; provided,
however, that such Opinion of Counsel shall not be required to express an
opinion as to the fair value of the Indenture Trust Estate. Counsel rendering
any such opinion may rely, without independent investigation, on the accuracy
and validity of any certificate or other instrument delivered to the Indenture
Trustee in connection with any such action.

                  SECTION 9.2 Supplemental Indentures with Consent of
Noteholders. The Issuer and the Indenture Trustee, when authorized by an Issuer
Order, also may, with prior notice to the Rating Agencies and with the consent

                  (ii)     reduce the percentage of the Outstanding Amount of

waived without the consent of the Noteholder of each Outstanding Note affected
thereby;

                  (vi)     modify any of the provisions of this Indenture in
such manner as to affect the calculation of the amount of any payment of

calculation of any of the individual components of such calculation) or to
affect the rights of the Noteholders to the benefit of any provisions for the
mandatory redemption of the Notes contained herein; or

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

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

Trustee of any supplemental indenture pursuant to this Section, the Indenture

14.1 Indenture

                                       61

<PAGE>

Trustee shall mail to the Noteholders of the Notes to which such amendment or
supplemental indenture relates a notice setting forth in general terms the
substance of such supplemental indenture. Any failure of the Indenture Trustee
to mail such notice, or any defect therein, shall not, however, in any way
impair or affect the validity of any such supplemental indenture.

                  SECTION 9.3 Execution of Supplemental Indentures. In
executing, or permitting the additional trusts created by, any supplemental
indenture permitted by this Article IX or the modifications thereby of the
trusts created by this Indenture, the Indenture Trustee shall be entitled to
receive, and subject to Sections 6.1 and 6.2, shall be fully protected in
relying upon, an Opinion of Counsel stating that the execution of such
supplemental indenture is authorized or permitted by this Indenture. The
Indenture Trustee may, but shall not be obligated to, enter into any such
supplemental indenture that affects the Indenture Trustee's own rights, duties,
liabilities or immunities under this Indenture or otherwise.

                  SECTION 9.4 Effect of Supplemental Indenture. Upon the
execution of any supplemental indenture pursuant to the provisions hereof, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith with respect to the Notes affected thereby, and the respective rights,
limitations of rights, obligations, duties, liabilities and immunities under
this Indenture of the Indenture Trustee, the Issuer and the Noteholders shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

                  SECTION 9.5 Conformity with Trust Indenture Act. Every
amendment of this Indenture and every supplemental indenture executed pursuant
to this Article IX shall conform to the requirements of the Trust Indenture Act
as then in effect so long as this Indenture shall then be qualified under the
Trust Indenture Act.

                  SECTION 9.6 Reference in Notes to Supplemental Indentures.
Notes authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article IX may, and if required by the Indenture
Trustee

14.1 Indenture

shall, bear a notation in form approved by the Indenture Trustee as to any
matter provided for in such supplemental indenture. If the Issuer or the
Indenture Trustee shall so determine, new Notes so modified as to conform, in
the opinion of the Indenture Trustee and the Issuer, to any such supplemental
indenture may be prepared and executed by the Issuer and authenticated and
delivered by the Indenture Trustee in exchange for Outstanding Notes.

                                    ARTICLE X

                              Redemption of Notes

                  SECTION 10.1 Redemption. The Indenture Trustee shall, upon
receipt of written notice from the Servicer pursuant to Section 6.1 of the
Administration Agreement, give prompt written notice to the Noteholders of the
occurrence of such event. In the event that the assets of the Trust are sold
pursuant to Section 6.1 of the Administration Agreement, that portion of the
amounts on deposit in the Trust Accounts to be distributed to the Noteholders
shall be paid to the Noteholders as provided in Sections 2.7 and 2.8 of the
Administration Agreement. If amounts are to be paid to Noteholders pursuant to
this Section 10.1, the notice of such event from the Indenture Trustee to the
Noteholders shall include notice of the redemption of Notes by application of
such amounts on the next Distribution Date which is not sooner than 15 days
after the date of such notice (the "Redemption Date"), whereupon all such
amounts shall be payable on the Redemption Date.

                  SECTION 10.2 Form of Redemption Notice. Notice of redemption
under Section 10.1 shall be given by the Indenture Trustee by first-class mail,
postage prepaid, or by facsimile, mailed or transmitted on or prior to the
applicable Redemption Date to each Noteholder, as of the close of business on
the Record Date preceding the applicable Redemption Date, at such Noteholder's
address or facsimile number appearing in the Note Register.

                  All notices of redemption shall state:

                  (i)      the Redemption Date;

                  (ii)     the Redemption Price; and

14.1 Indenture

                                       63

<PAGE>

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

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

                  SECTION 10.3 Notes Payable on Redemption Date. The Notes or
portions thereof to be redeemed shall on the Redemption Date become due and
payable at the Redemption Price and (unless the Issuer shall default in the
payment of the Redemption Price) no interest shall accrue on the Redemption
Price for any period after the date to which accrued interest is calculated for
purposes of calculating the Redemption Price.

                                   ARTICLE XI

                  SECTION 11.1 Compliance Certificates and Opinions, etc. Upon
any application or request by the Issuer to the Indenture Trustee to take any
action under any provision of this Indenture, the Issuer shall furnish to the
Indenture Trustee and the Rating Agencies (i) an Officers' Certificate of the
Issuer stating that all conditions precedent, if any, provided for in this
Indenture relating to the proposed action have been complied with, (ii) an
Opinion of Counsel stating that in the opinion of such counsel all such
conditions precedent, if any, have been complied with and (iii) (if required by
the TIA) an Independent Certificate from a firm of certified public accountants
meeting the applicable requirements of this Section, except that, in the case of
any such application or request as to which the furnishing of such documents is
specifically required by any provision of this Indenture, no additional
certificate or opinion need be furnished.

<PAGE>

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

                  (i)      a statement that each signatory of such certificate
or opinion has read or has caused to be read such covenant or condition and the
definitions herein relating thereto;

                  (ii)     a brief statement as to the nature and scope of the
examination or investigation upon which the statements or opinions contained in
such certificate or opinion are based;

                  (iii)    a statement that, in the opinion of each such
signatory, such signatory has made such examination or investigation as is
necessary to enable such signatory to express an informed opinion as to whether
or not such covenant or condition has been complied with; and

                  (iv)     a statement as to whether, in the opinion of each
such signatory, such condition or covenant has been complied with.

         (b)      (i)      Prior to the deposit of any Collateral or other
property or securities with the Indenture Trustee that is to be made the basis
for the release of any property or securities subject to the lien of this
Indenture, the Issuer shall, in addition to any obligation imposed in Section
11.1(a) or elsewhere in this Indenture, furnish to the Indenture Trustee and the
Rating Agencies an Officers' Certificate of the Issuer certifying or stating the
opinion of each person signing such certificate as to the fair value (within 90
days of such deposit) to the Issuer of the Collateral or other property or
securities to be so deposited.

                  (ii)     Whenever the Issuer is required to furnish to the
Indenture Trustee and the Rating Agencies an Officers' Certificate of the Issuer
certifying or stating the opinion of any signer thereof as to the matters
described in clause (i) above, the Issuer shall also deliver to the Indenture
Trustee an Independent Certificate as to the same matters, if the fair value to
the Issuer of the securities to be so deposited and of all other such securities
made the basis of any such withdrawal or release since the commencement of the
then-current fiscal year of the Issuer, as set forth in the certificates
delivered pursuant to clause (i) above and this clause (ii), is 10% or more of
the Outstanding Amount of the Notes, but such

14.1 Indenture

                                       65

<PAGE>

a certificate need not be furnished with respect to any securities so deposited,
if the fair value thereof to the Issuer as set forth in the related Officers'
Certificate is less than $25,000 or less than one percent of the Outstanding
Amount of the Notes.

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

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

                  (v)      Notwithstanding Section 2.9 or any other provision of
this Section, the Issuer may, without compliance with the requirements of the
other provisions of this Section, (A) collect, liquidate, sell or otherwise
dispose of Trust Student Loans as and to the extent permitted or required by the
Basic Documents, (B) make cash payments out of the Trust Accounts as and to the
extent permitted or required by the Basic Documents and (C) convey to the
Depositor, the Servicer or another eligible lender those specified Trust Student
Loans as and to the extent permitted or required by and in accordance with
Section 8.4(c) hereof and Section 6 of the Sale Agreement, Section 3.5 of the
Servicing Agreement or Section

14.1 Indenture

                                       66

<PAGE>

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.

<PAGE>

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

                  SECTION 11.3 Acts of Noteholders. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Noteholders may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Noteholders in person or by agents duly appointed in writing; and except as
herein otherwise expressly provided such action shall become effective when such
instrument or instruments are delivered to the Indenture Trustee, and, where it
is hereby expressly required, to the Issuer. Such instrument or instruments (and
the action embodied therein and evidenced thereby) are herein sometimes referred
to as the "Act" of the Noteholders signing such instrument or instruments. Proof
of execution of any such instrument or of a writing appointing any such agent
shall be sufficient for any purpose of this Indenture and (subject to Section
6.1) conclusive in favor of the Indenture Trustee and the Issuer, if made in the
manner provided in this Section.

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

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

         (d)      Any request, demand, authorization, direction, notice,
consent, waiver or other action by the Noteholder of any Notes shall bind the
Noteholder of every Note issued upon registration of transfer thereof or in
exchange therefor or in lieu thereof, in respect of anything done, omitted or
suffered to be done by

14.1 Indenture

                                       68

<PAGE>

the Indenture Trustee or the Issuer in reliance thereon, whether or not notation
of such action is made upon such Note.

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

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

         (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 2003-9, 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 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

14.1 Indenture

                                       69
<PAGE>

of Fitch, at the following address: One State Street Plaza, New York, New York
10004, Attention: Municipal Structured Finance Group; or as to each of the
foregoing, at such other address as shall be designated by written notice to the
other parties.

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

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

                  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.

<PAGE>

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

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

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

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

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

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

                  SECTION 11.11 Benefits of Indenture. Nothing in this Indenture
or in the Notes, express or implied, shall give to any Person, other than the
parties hereto and their successors hereunder, and the Noteholders, and any
other party

14.1 Indenture

                                       71
<PAGE>

secured hereunder, and any other Person with an ownership interest in any part
of the Indenture Trust Estate, any benefit or any legal or equitable right,
remedy or claim under this Indenture.

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

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

14.1 Indenture

                                       72
<PAGE>

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
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

14.1 Indenture

                                       73
<PAGE>

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.

14.1 Indenture

                                       74
<PAGE>

                  IN WITNESS WHEREOF, the Issuer, the Eligible Lender Trustee
and the Indenture Trustee have caused this Indenture to be duly executed by

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

                  The Class A-1 Notes are and will be equally and ratably
secured by the Collateral pledged as security therefor as provided in the
Indenture. The Class A-1 Notes are prior in order of principal payment to the
Class A-2, Class A-3, Class A-4 and Class B Notes and 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 in
December 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 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 mean the rate determined by the following formula: x +
[17/31 * (y-x)] plus 0.01% where: x = Three-Month LIBOR, and y = Four-Month
LIBOR, as determined on the second Business Day before the beginning of the
Accrual Period.

                  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

                                 Exhibit A-1-4
<PAGE>

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

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

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

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

                                 Exhibit A-1-5
<PAGE>

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

                  Each Noteholder or Note Owner, by acceptance of a Note or, in
the case of a Note Owner, a beneficial interest in a Note, covenants and agrees
that by accepting the benefits of the Indenture such Noteholder or Note Owner
will not at any time institute against the 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.

                  Upon acquisition or transfer a Note or a beneficial interest
in a Note, as the case may be, by, for or with the assets of, an employee
benefit plan or other retirement arrangement ("Plan"), such Note Owner shall be
deemed to have represented that such acquisition or purchase will not constitute
or otherwise result in: (i) in the case of a Plan subject to Section 406 of
Employee Retirement Income Security Act of 1974, as amended ("ERISA") or Section
4975 of the Internal Revenue Code of 1986, as amended ("Code"), 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 and (ii)
in the case of a Plan subject to a substantially similar federal, state, local
or foreign law ("Similar Law"), a non-exempt violation of such substantially
Similar Law. Any transfer found to have been made in violation of such deemed
representation shall be null and void and of no effect.

                  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.

                                 Exhibit A-1-6
<PAGE>

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

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

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

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

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

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

                  Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither 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.

                                 Exhibit A-1-7
<PAGE>

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.

                  SLM Student Loan Trust 2003-9, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the principal sum of FOUR HUNDRED NINE MILLION AND NO/100
DOLLARS ($409,000,000) payable on each Distribution Date in an amount equal to
the aggregate amount, if any, payable to Class A-2 Noteholders on such

banking corporation, as Indenture Trustee (the "Indenture Trustee") (capitalized
terms used but not defined herein being defined in Appendix A to the Indenture,
which also contains rules as to usage that shall be applicable herein);
provided, however, that the entire unpaid principal amount of this Note shall be
due and payable on June 15, 2011 (the "Class A-2 Maturity Date").

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

number of days elapsed in each Accrual Period divided by 360. Such principal of

forth on the reverse hereof, which shall have the same effect as though fully
set forth on the face of this Note.

this Note shall not be entitled to any benefit under the Indenture referred to

                  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

all indentures supplemental thereto reference is hereby made for a statement of
the respective rights and obligations thereunder of the Issuer, the Indenture

Indenture.

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

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

                  Interest on the Class A-2 Notes shall be payable on each
Distribution Date on the principal amount outstanding of the Class A-2 Notes
until the principal amount thereof is paid in full, at a rate per annum equal to
the Class A-2 Rate. The "Class A-2 Rate" for each Accrual Period shall be equal
to Three-Month LIBOR as determined on the second Business Day before the
beginning of that Accrual Period plus 0.04%. For the initial Accrual Period, the
Class A-2 Rate shall mean the rate determined by the following formula: x +
[17/31 * (y-x)] plus 0.04% where: x = Three-Month LIBOR, and y = Four-Month
LIBOR, as determined on the second Business Day before the beginning of the
Accrual Period.

<PAGE>

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

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

                                  Exhibit A-2-5
<PAGE>

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

                  Each Noteholder or Note Owner, by acceptance of a Note or, in
the case of a Note Owner, a beneficial interest in a Note, covenants and agrees
that by accepting the benefits of the Indenture such Noteholder or Note Owner
will not at any time institute against the 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.

                  Upon acquisition or transfer a Note or a beneficial interest
in a Note, as the case may be, by, for or with the assets of, an employee
benefit plan or other retirement arrangement ("Plan"), such Note Owner shall be
deemed to have represented that such acquisition or purchase will not constitute
or otherwise result in: (i) in the case of a Plan subject to Section 406 of
Employee Retirement Income Security Act of 1974, as amended ("ERISA") or Section
4975 of the Internal Revenue Code of 1986, as amended ("Code"), 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 and (ii)
in the case of a Plan subject to a substantially similar federal, state, local
or foreign law ("Similar Law"), a non-exempt violation of such substantially
Similar Law. Any transfer found to have been made in violation of such deemed
representation shall be null and void and of no effect.

                  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.

                                  Exhibit A-2-6
<PAGE>

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

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

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

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

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

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

                  Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither 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

                                  Exhibit A-2-7
<PAGE>

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.

                  SLM Student Loan Trust 2003-9, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the principal sum of TWO HUNDRED SIXTY-TWO MILLION AND
NO/100 DOLLARS ($262,000,000) payable on each Distribution Date in an amount
equal to the aggregate amount, if any, payable to Class A-3 Noteholders on such
Distribution Date in respect of principal of the Notes pursuant to Section 3.1
of the Indenture dated as of August 1, 2003, among the Issuer, Chase Manhattan
Bank USA, National Association, a Delaware banking corporation, as Eligible
Lender Trustee on behalf of the Issuer, and The Bank of New York, a New York
banking corporation, as Indenture Trustee (the "Indenture Trustee") (capitalized
terms used but not defined herein being defined in Appendix A to the Indenture,
which also contains rules as to usage that shall be applicable herein);
provided, however, that the entire unpaid principal amount of this Note shall be
due and payable on December 17, 2012 (the "Class A-3 Maturity Date").

                  The Issuer shall pay interest on this Note at the rate per
annum equal to the Class A-3 Rate (as defined on the reverse hereof), on each
Distribution Date until the principal of this Note is paid or made available for
payment, on the principal amount of this Note outstanding on the preceding
Distribution Date (after giving effect to all payments of principal made on the
preceding Distribution Date), subject to certain limitations contained in
Section 3.1 of the Indenture. Interest on this Note shall accrue from and
including the preceding Distribution Date (or, in the case of the first Accrual
Period, the Closing Date) to but excluding the following Distribution Date (each
an "Accrual Period"). Interest shall be calculated on the basis of the actual
number of days elapsed in each Accrual Period divided by 360. Such principal of
and interest on this Note shall be paid in the manner specified on the reverse
hereof.

                  The principal of and interest on this Note are payable in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. All payments made by the

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.

<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") and Floating Rate Class B
Student Loan-Backed Notes (the "Class B Notes" and, together with the Class A-1
Notes, the Class A-2 Notes, the Class A-3 Notes and the Class A-4 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. The Class A-1 Notes and 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 payments to the Class A-4 and Class B Notes and 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 in
December 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 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 mean the rate determined by the following formula: x +
[17/31 * (y-x)] plus 0.11% where: x = Three-Month LIBOR, and y = Four-Month
LIBOR, as determined on the second Business Day before the beginning of the
Accrual Period.

                                  Exhibit A-3-4
<PAGE>

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

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

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

                  Each Noteholder or Note Owner, by acceptance of a Note or, in
the case of a Note Owner, a beneficial interest in a Note, covenants and agrees
that by accepting the benefits of the Indenture such Noteholder or Note Owner
will not at any time institute against the 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.

                  Upon acquisition or transfer a Note or a beneficial interest
in a Note, as the case may be, by, for or with the assets of, an employee
benefit plan or other retirement arrangement ("Plan"), such Note Owner shall be
deemed to have represented that such acquisition or purchase will not constitute
or otherwise result in: (i) in the case of a Plan subject to Section 406 of
Employee Retirement Income Security Act of 1974, as amended ("ERISA") or Section
4975 of the Internal Revenue Code of 1986, as amended ("Code"), 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 and (ii)
in the case of a Plan subject to a substantially similar federal, state, local
or foreign law ("Similar Law"), a non-exempt violation of such substantially
Similar Law. Any transfer found to have been made in violation of such deemed
representation shall be null and void and of no effect.

                  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.

<PAGE>

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

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

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

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

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

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

                  Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither 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

                                  Exhibit A-3-7
<PAGE>

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.

                  SLM Student Loan Trust 2003-9, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the principal sum of FIVE HUNDRED MILLION AND NO/100 DOLLARS
($500,000,000) payable on each Distribution Date in an amount equal to the
result obtained by multiplying (i) a fraction the numerator of which is
$500,000,000 and the denominator of which is $528,672,000 by (ii) the aggregate
amount, if any, payable to Class A-4 Noteholders on such Distribution Date in
respect of principal of the Notes pursuant to Section 3.1 of the Indenture dated
as of August 1, 2003, among the Issuer, Chase Manhattan Bank USA, National
Association, a Delaware banking corporation, as Eligible Lender Trustee on
behalf of the Issuer, and The Bank of New York, a New York banking corporation,
as Indenture Trustee (the "Indenture Trustee") (capitalized terms used but not
defined herein being defined in Appendix A to the Indenture, which also contains
rules as to usage that shall be applicable herein); provided, however, that the
entire unpaid principal amount of this Note shall be due and payable on March
15, 2019 (the "Class A-4 Maturity Date").

                  The Issuer shall pay interest on this Note at the rate per
annum equal to the Class A-4 Rate (as defined on the reverse hereof), on each
Distribution Date until the principal of this Note is paid or made available for
payment, on the principal amount of this Note outstanding on the preceding
Distribution Date (after giving effect to all payments of principal made on the
preceding Distribution Date), subject to certain limitations contained in
Section 3.1 of the Indenture. Interest on this Note shall accrue from and
including the preceding Distribution Date (or, in the case of the first Accrual
Period, the Closing Date) to but excluding the following Distribution Date (each
an "Accrual Period"). Interest shall be calculated on the basis of the actual
number of days elapsed in each Accrual Period divided by 360. Such principal of
and interest on this Note shall be paid in the manner specified on the reverse
hereof.

                  The principal of and interest on this Note are payable in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. All payments made by the
Issuer 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.

<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") and Floating Rate Class B
Student Loan-Backed Notes (the "Class B Notes" and, together with the Class A-1
Notes, the Class A-2 Notes, the Class A-3 Notes and the Class A-4 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. 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 principal payment to the Class B Notes and 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 in
December 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 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 mean the rate determined by the following formula: x +
[17/31 * (y-x)] plus 0.20% where: x = Three-Month LIBOR, and y = Four-Month
LIBOR, as determined on the second Business Day before the beginning of the
Accrual Period.

                                  Exhibit A-4-5
<PAGE>

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

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

                                  Exhibit A-4-6
<PAGE>

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

                  Each Noteholder or Note Owner, by acceptance of a Note or, in
the case of a Note Owner, a beneficial interest in a Note, covenants and agrees
that by accepting the benefits of the Indenture such Noteholder or Note Owner
will not at any time institute against the 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.

                  Upon acquisition or transfer a Note or a beneficial interest
in a Note, as the case may be, by, for or with the assets of, an employee
benefit plan or other retirement arrangement ("Plan"), such Note Owner shall be
deemed to have represented that such acquisition or purchase will not constitute
or otherwise result in: (i) in the case of a Plan subject to Section 406 of
Employee Retirement Income Security Act of 1974, as amended ("ERISA") or Section
4975 of the Internal Revenue Code of 1986, as amended ("Code"), 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 and (ii)
in the case of a Plan subject to a substantially similar federal, state, local
or foreign law ("Similar Law"), a non-exempt violation of such substantially
Similar Law. Any transfer found to have been made in violation of such deemed
representation shall be null and void and of no effect.

                  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.

                                  Exhibit A-4-7
<PAGE>

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

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

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

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

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

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

                  Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither The Bank of New York, in its

                  SLM Student Loan Trust 2003-9, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the principal sum of TWENTY-EIGHT MILLION, SIX HUNDRED
SEVENTY-TWO THOUSAND AND NO/100 DOLLARS ($28,672,000) payable on each
Distribution Date in an amount equal to the result obtained by multiplying (i) a
fraction the numerator of which is $28,672,000 and the denominator of which is
$528,672,000 by (ii) the aggregate amount, if any, payable to Class A-4
Noteholders on such Distribution Date in respect of principal of the Notes
pursuant to Section 3.1 of the Indenture dated as of August 1, 2003, among the
Issuer, Chase Manhattan Bank USA, National Association, a Delaware banking
corporation, as Eligible Lender Trustee on behalf of the Issuer, and The Bank of
New York, a New York banking corporation, as Indenture Trustee (the "Indenture
Trustee") (capitalized terms used but not defined herein being defined in
Appendix A to the Indenture, which also contains rules as to usage that shall be
applicable herein); provided, however, that the entire unpaid principal amount
of this Note shall be due and payable on March 15, 2019 (the "Class A-4 Maturity
Date").

                  The Issuer shall pay interest on this Note at the rate per
annum equal to the Class A-4 Rate (as defined on the reverse hereof), on each
Distribution Date until the principal of this Note is paid or made available for
payment, on the principal amount of this Note outstanding on the preceding
Distribution Date (after giving effect to all payments of principal made on the
preceding Distribution Date), subject to certain limitations contained in
Section 3.1 of the Indenture. Interest on this Note shall accrue from and
including the preceding Distribution Date (or, in the case of the first Accrual
Period, the Closing Date) to but excluding the following Distribution Date (each
an "Accrual Period"). Interest shall be calculated on the basis of the actual
number of days elapsed in each Accrual Period divided by 360. Such principal of
and interest on this Note shall be paid in the manner specified on the reverse
hereof.

                  The principal of and interest on this Note are payable in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. All payments made by the
Issuer 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.

<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") and Floating Rate Class B
Student Loan-Backed Notes (the "Class B Notes" and, together with the Class A-1
Notes, the Class A-2 Notes, the Class A-3 Notes and the Class A-4 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. 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 principal payment to the Class B Notes and 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 in
December 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 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 mean the rate determined by the following formula: x +
[17/31 * (y-x)] plus 0.20% where: x = Three-Month LIBOR, and y = Four-Month
LIBOR, as determined on the second Business Day before the beginning of the
Accrual Period.

                                 Exhibit A-4-15

<PAGE>

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

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

                                 Exhibit A-4-16

<PAGE>

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

                  Each Noteholder or Note Owner, by acceptance of a Note or, in
the case of a Note Owner, a beneficial interest in a Note, covenants and agrees
that by accepting the benefits of the Indenture such Noteholder or Note Owner
will not at any time institute against the 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.

                  Upon acquisition or transfer a Note or a beneficial interest
in a Note, as the case may be, by, for or with the assets of, an employee
benefit plan or other retirement arrangement ("Plan"), such Note Owner shall be
deemed to have represented that such acquisition or purchase will not constitute
or otherwise result in: (i) in the case of a Plan subject to Section 406 of
Employee Retirement Income Security Act of 1974, as amended ("ERISA") or Section
4975 of the Internal Revenue Code of 1986, as amended ("Code"), 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 and (ii)
in the case of a Plan subject to a substantially similar federal, state, local
or foreign law ("Similar Law"), a non-exempt violation of such substantially
Similar Law. Any transfer found to have been made in violation of such deemed
representation shall be null and void and of no effect.

                  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.

                                 Exhibit A-4-17

<PAGE>

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

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

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

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

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

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

                  Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither 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

                                 Exhibit A-4-18

<PAGE>

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.

                  SLM Student Loan Trust 2003-9, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the principal sum of FORTY-SIX MILLION, SEVENTY-NINE
THOUSAND AND NO/100 DOLLARS ($46,079,000) payable on each Distribution Date in
an amount equal to the aggregate amount, if any, payable to Class B Noteholders
on such Distribution Date in respect of principal of the Notes pursuant to
Section 3.1 of the Indenture dated as of August 1, 2003, among the Issuer, Chase
Manhattan Bank USA, National Association, a Delaware banking corporation, as
Eligible Lender Trustee on behalf of the Issuer, and The Bank of New York, a New
York banking corporation, as Indenture Trustee (the "Indenture Trustee")
(capitalized terms used but not defined herein being defined in Appendix A to
the Indenture, which also contains rules as to usage that shall be applicable
herein); provided, however, that the entire unpaid principal amount of this Note
shall be due and payable on March 15, 2024 (the "Class B Maturity Date").

                  The Issuer shall pay interest on this Note at the rate per
annum equal to the Class B Rate (as defined on the reverse hereof), on each
Distribution Date until the principal of this Note is paid or made available for
payment, on the principal amount of this Note outstanding on the preceding
Distribution Date (after giving effect to all payments of principal made on the
preceding Distribution Date), subject to certain limitations contained in
Section 3.1 of the Indenture. Interest on this Note shall accrue from and
including the preceding Distribution Date (or, in the case of the first Accrual
Period, the Closing Date) to but excluding the following Distribution Date (each

hereof.

                  The principal of and interest on this Note are payable in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. All payments made by the
Issuer 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.

                                [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 Floating Rate Class A-4
Student Loan-Backed Notes (the "Class A-4 Notes" and, together with the Class
A-1 Notes, the Class A-2 Notes, the Class A-3 Notes and 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. The
Class A-1, Class A-2 Notes, Class A-3 Notes and Class A-4 Notes are prior in
order of principal payment, and are senior, to the Class B 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 in
December 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 shall be equal to
Three-Month LIBOR as determined on the second business day before the beginning
of that Accrual Period plus 0.55%. For the initial Accrual Period, the Class B
Rate shall mean the rate determined by the following formula: x + [17/31 *
(y-x)] plus 0.55% where: x = Three-Month LIBOR, and y = Four-Month LIBOR, as
determined on the second Business Day before the beginning of the Accrual
Period.

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

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

                  Each Noteholder or Note Owner, by acceptance of a Note or, in
the case of a Note Owner, a beneficial interest in a Note, covenants and agrees
that by accepting the benefits of the Indenture such Noteholder or Note Owner
will not at any time institute against the 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.

                  Upon acquisition or transfer a Note or a beneficial interest
in a Note, as the case may be, by, for or with the assets of, an employee
benefit plan or other retirement arrangement ("Plan"), such Note Owner shall be
deemed to have represented that such acquisition or purchase will not constitute
or otherwise result in: (i) in the case of a Plan subject to Section 406 of
Employee Retirement Income Security Act of 1974, as amended ("ERISA") or Section
4975 of the Internal Revenue Code of 1986, as amended ("Code"), 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 and (ii)
in the case of a Plan subject to a substantially similar federal, state, local
or foreign law ("Similar Law"), a non-exempt violation of such substantially
Similar Law. Any transfer found to have been made in violation of such deemed
representation shall be null and void and of no effect.

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

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

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

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

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

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

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

                  Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither 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

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;
