expressly made by the Interim Eligible Lender Trustee. In particular, but not by

liable for any error of judgment made by a responsible officer of the Interim
Eligible Lender Trustee.

                  2.       No provision of this Agreement, the Purchase
Agreement or the Sale Agreement shall require the Interim Eligible Lender
Trustee to expend or risk funds or otherwise incur any financial liability in
the performance of any of its rights or powers hereunder or under the Purchase
Agreement or the Sale Agreement, if the Interim Eligible Lender Trustee shall
have reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured or provided
to it.

                  3.       The Interim Eligible Lender Trustee shall not be
responsible for or in respect of the validity or sufficiency of this Agreement

Purchase Agreement, the Sale Agreement or this Agreement, nor the consummation
by it of the transactions contemplated thereby or hereby nor compliance by it
with any of the terms or provisions thereof or hereof will contravene any
Federal or Delaware state law, governmental rule or regulation governing the
banking or trust powers of the Interim Eligible Lender Trustee or any judgment
or order binding on it, or constitute any default under its charter documents or
by-laws or any indenture, mortgage, contract, agreement or instrument to which
it is a party or by which any of its properties may be bound.

                  4.       It is and will maintain its status as an "eligible

the name of the Interim Eligible Lender Trustee.

                                   ARTICLE VI

                                  ARTICLE VII

                     TERMINATION OF INTERIM TRUST AGREEMENT

                  This Agreement (other than Article VI) and the trust created
hereby shall terminate and be of no further force or effect upon the earlier of

                                  ARTICLE VIII

                   SUCCESSOR INTERIM ELIGIBLE LENDER TRUSTEES

                  Section 8.1 Eligibility Requirements for Interim Eligible
Lender Trustee. The Interim Eligible Lender Trustee shall at all times be a
corporation or 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

                                      -5-

<PAGE>

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

                                      -6-

<PAGE>

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.

                                   ARTICLE IX

                                  MISCELLANEOUS

                  Section 9.1 Supplements and Amendments. This Agreement may be
amended by the Depositor and the Interim Eligible Lender Trustee, with prior
written notice to the Rating Agencies, without the consent of any of the
Noteholders or any Swap Counterparty, to cure any ambiguity, to correct or
supplement any provisions in this Agreement or for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions in
this Agreement; provided, however, that such action shall not, as evidenced by
an Opinion of Counsel, adversely affect in any material respect the interests of
any Noteholder or any Swap Counterparty.

                  This Agreement may also be amended from time to time by the
Depositor and the Interim Eligible Lender Trustee, with prior written notice to
any Swap Counterparty and the Rating Agencies, with the consent of the
Noteholders evidencing not less than a majority of the Outstanding Amount of the
Notes, for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Agreement; provided, however, that no
such amendment shall reduce the aforesaid percentage of the Outstanding Amount
of the Notes required to consent to any such amendment, without the consent of
all the outstanding Noteholders.

                  This Agreement may also be amended from time to time by the
Depositor and the Interim Eligible Lender Trustee, with prior written notice to
the Rating Agencies, and, if any

                                      -7-

<PAGE>

such amendment would adversely affect, in a material respect, the interests of
any Swap Counterparty, with the consent of that Swap Counterparty.

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

                  It shall not be necessary for the consent of the Noteholders
or any Swap Counterparty pursuant to this Section to approve the particular form
of any proposed amendment or consent, but it shall be sufficient if such consent
shall approve the substance thereof. The manner of obtaining such consents and
of evidencing the authorization of the execution thereof shall be subject to
such reasonable requirements as the Interim Eligible Lender Trustee may
prescribe.

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

                  Section 9.2 Notices. Unless otherwise expressly specified or
permitted by the terms hereof, all notices shall be in writing and shall be
deemed given upon receipt by the intended recipient or three Business Days after
mailing if mailed by certified mail, postage prepaid (except that notice to the

                                    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

or without steel engraved borders), all as determined by the officers executing
such Notes, as evidenced by their execution of such Notes.

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

The Bank of New York, as custodian for DTC (the "DTC Custodian"), and registered
in the name of Cede & Co. as initial nominee for DTC.

                  The Reset Rate Notes denominated in U.S. Dollars may be
offered and sold only to QIBs, and initially will be represented by interests in
a global registered note certificate (the "U.S. Rule 144A Global Note
Certificate"), deposited on the Closing Date with the DTC Custodian and
registered in the name of Cede & Co. as initial nominee for DTC. At all times,
the entire Outstanding Amount of the Reset Rate Notes then denominated in U.S.
Dollars will be allocated to the corresponding U.S. Rule 144A Global Note
Certificate. On the Closing Date, a corresponding Non-U.S. Rule 144A Global Note
Certificate (as defined below) and Regulation S Global Note Certificate (as
defined below) for the Reset Rate Notes will be deposited with the Regulation S
Custodian (as defined below), registered in the name of The Bank of New York
Depository (Nominees) Limited, as initial joint nominee for Euroclear and
Clearstream (the "Joint Nominee"), and each such global registered note
certificate will have an outstanding principal balance of zero for so long as
the Reset Rate Notes are denominated in U.S. Dollars.

                  The Reset Rate Notes denominated in a currency other than U.S.
Dollars (including the Reset Rate Notes during their initial Reset Period) may
be offered and sold only to

                                      -3-

<PAGE>

QIBs in reliance on Rule 144A or to a non-U.S. Person (as defined in Regulation
S) outside the United States of America in reliance on Regulation S, as
applicable, and will be represented by interests in either a Rule 144A global
registered note certificate (the "Non-U.S. Rule 144A Global Note Certificate")
or a Regulation S global registered note certificate (the "Regulation S Global
Note Certificate," and collectively with the Non-U.S. Rule 144A Global Note
Certificate, the "Non-U.S. Global Note Certificates"). Each Non-U.S. Global Note
Certificate will be registered in the name of the Joint Nominee, and will be
deposited on the Closing Date with The Bank of New York, acting through its
London branch, as common depositary for Euroclear and Clearstream (the
"Regulation S Custodian" and together with the DTC Custodian, the "Custodian").
At all times, there will be only one Non-U.S. Rule 144A Global Note Certificate
and one Regulation S Global Note Certificate for the Reset Rate Notes. At all
times, the entire Outstanding Amount of the Reset Rate Notes denominated in a
currency other than U.S. Dollars will be allocated between the corresponding
Non-U.S. Rule 144A Global Note Certificate and Regulation S Global Note
Certificate for the Reset Rate Notes. On the Closing Date, a corresponding U.S.
Rule 144A Global Note Certificate will be deposited with the DTC Custodian and
will have an outstanding principal balance of zero for so long as the Reset Rate
Notes are denominated in a currency other than U.S. Dollars.

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

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

                  The Indenture Trustee shall upon Issuer Order authenticate and
deliver Notes for original issue in an aggregate principal amount of
$2,531,393,600, using an exchange rate of $1.6884 = L1.00 with respect to the
principal amount of L396,500,000 of the Reset Rate Notes included in such
amount. The aggregate principal amount of Notes Outstanding at any time may not
exceed such amount except as provided in Section 2.5. On each Spread
Determination Date, upon receipt of an Issuer Order, the Indenture Trustee shall
deliver a revised Schedule A for the Reset Rate Notes to the Custodians.

                  Each Note shall be dated the date of its authentication. The
Floating Rate Class A Notes (other than the Class A-5 Notes) shall be issuable
as registered notes in minimum denominations of $1,000 and additional increments
of $1,000. The Class A-5 Notes shall be issuable as registered notes in minimum
denominations of $250,000 and additional increments of $1,000. The Class B Notes
shall be issuable as registered Class B Notes in minimum denominations of
$100,000 and additional increments of $1,000.

                  During any Reset Period when the Reset Rate Notes are
denominated in U.S. Dollars, they shall be issued in minimum denominations of
$250,000, and additional increments of $1. During any Reset Period when the
Reset Rate Notes are denominated in a currency other than U.S. Dollars, they
shall be issued in minimum denominations of the applicable currency equivalent
(approximately) of $250,000 and additional increments of the applicable currency

                                      -4-

<PAGE>

equivalent of $1 (which shall be determined by reference to the exchange rate
to be set forth in the related cross-currency swap agreement); provided, that
during any Reset Period when the Reset Rate Notes are denominated in Pounds
Sterling (including the initial Reset Period), the Reset Rate Notes shall be
issued in minimum denominations of L100,000 and additional increments of L1; and
provided, further, that during any Reset Period when the Reset Rate Notes are
denominated in Euros, the Reset Rate Notes shall be issued in minimum
denominations of E100,000 and additional increments of E1.

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

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

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

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

                  If a Person other than the Indenture Trustee is appointed by
the Issuer as Note Registrar, the Issuer shall give the Indenture Trustee prompt
written notice of the appointment of such Note Registrar and of the location,
and any change in the location, of the Note Register, and the Indenture Trustee
shall have the right to inspect the Note Register at all reasonable times and to
obtain copies thereof, and the Indenture Trustee shall have the right to rely
upon a certificate

                                      -5-

<PAGE>

executed on behalf of the Note Registrar by an Executive Officer thereof as to
the names and addresses of the Noteholders and the principal amounts and number
of such Notes.

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

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

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

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

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

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

                  The preceding provisions of this Section notwithstanding, the
Issuer shall not be required to make and the Note Registrar need not register
transfers or exchanges of Notes

                                      -6-

selected for redemption or of any Note for a period of 15 days preceding the due
date for any payment with respect to the Note.

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

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

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

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

                  Section 2.6 Persons Deemed Owner. Prior to due presentment for
registration of transfer of any Note, the Issuer, the Indenture Trustee and any
agent of the Issuer or the Indenture Trustee may treat the Person in whose name
any Note is registered (as of the day of determination) as the owner of such
Note for the purpose of receiving payments of principal of, interest, if any, on
such Note and for all other purposes whatsoever, whether or not such Note be

                                      -7-

overdue, and neither the Issuer, the Indenture Trustee nor any agent of the
Issuer or the Indenture Trustee shall be affected by notice to the contrary.

                  Section 2.7 Payment of Principal and Interest; Note Interest
Shortfall. (a) The Floating Rate Notes shall accrue interest as provided in such
Floating Rate Notes, which shall be substantially in the form of Exhibits A-1,
A-2, A-3, A-4, A-5 and A-9 and the Reset Rate Notes shall accrue interest as
provided in such Reset Rate Notes, which shall be substantially in the form of
Exhibit A-6, A-7 or A-8, and such interest shall be payable on each applicable
Distribution Date as specified therein, subject to Section 3.1. Any installment
of interest or principal, if any, payable on any Note which is punctually paid
or duly provided for by the Issuer on the applicable Distribution Date shall be
paid to the Person in whose name such Note (or one or more Predecessor Notes) is
registered on the applicable Record Date by check mailed first-class, postage
prepaid to such Person's address as it appears on the Note Register on such
Record Date, except that, unless Definitive Notes have been issued pursuant to
Section 2.12, with respect to Notes registered on the Record Date in the name of
the nominee of the applicable Clearing Agency (initially, such nominee to be
Cede & Co.), as nominee for DTC, for the Floating Rate Notes and The Bank of New
York Depository (Nominees) Limited, as joint nominee for Euroclear and
Clearstream, for the Reset Rate Notes, payment shall be made by wire transfer in
immediately available funds to the account designated by such nominee and except
for the final installment of principal payable with respect to such Note on a
Distribution Date or on the Note Final Maturity Date for such Note which shall
be payable as provided below. The funds represented by any such checks returned
undelivered shall be held in accordance with Section 3.3.

                  (b) The principal of each class of Floating Rate Notes shall
be payable on each applicable Distribution Date as provided in the forms of
Notes set forth in Exhibits A-1, A-2, A-3, A-4, A-5 and A-9 and the principal of
the Reset Rate Notes shall be payable on each applicable Distribution Date as

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

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

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 applicable initial Clearing Agency by
the Issuer, or by the Indenture Trustee on behalf of the Issuer. Such Notes
shall initially be registered on the Note Register in the name of the nominee of
each initial Clearing Agency, and no Note Owner shall receive a definitive,
fully registered note (a "Definitive Note") representing such Note Owner's
interest in such Note, except as provided in Section 2.12. Unless and until
Definitive Notes have been issued to Note Owners pursuant to Section 2.12:

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

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

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

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

<PAGE>

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

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

                  Section 2.11 Notices to Clearing Agency. Whenever a notice or
other communication is required under this Indenture to be given to Noteholders,
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 the applicable Clearing Agency.

                  Section 2.12 Definitive Notes. If (i) the Administrator
advises the Indenture Trustee in writing that a Clearing Agency (a) is closed
for business for a continuous period of 14 days (other than by reason of
holiday, statutory or otherwise), (b) announces an intention to cease business
permanently (or does so and no alternative clearing system acceptable to the
Indenture Trustee is then available), or (c) at any time, is unwilling or unable
to continue as, or ceases to be, a clearing agency registered under all
applicable laws, and a successor clearing agency which is registered as a
clearing agency under all applicable laws is not appointed by the Administrator
within 90 days of such event, (ii) the Administrator at its option advises the
Indenture Trustee in writing that it elects to terminate the book-entry system
through that Clearing Agency or (iii) after the occurrence of an Event of
Default, a Servicer Default or an Administrator Default, Note Owners
representing beneficial interests aggregating at least a majority of the
Outstanding Amount of the applicable Notes advise the applicable Clearing Agency
(which shall then notify the Indenture Trustee) in writing that the continuation
of a book-entry system through such Clearing Agency is no longer in the best
interests of such Note Owners, then the Indenture Trustee shall cause such
Clearing Agency to notify all Note Owners cleared, through such Clearing Agency,
of the occurrence of any such event and of the availability of Definitive Notes
to Note Owners requesting the same. Upon surrender to the Indenture Trustee of
the typewritten Notes representing the Book-Entry Notes by a Clearing Agency,
accompanied by registration instructions, the Issuer shall execute and the
Indenture Trustee shall authenticate the Definitive Notes in accordance with the
instructions of such Clearing Agency, which shall include, without limitation,
the identity and payment instructions for all Noteholders of the applicable
Notes. None of the Issuer, the Note Registrar or the

                                      -10-

<PAGE>

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 of a Definitive Note by, for or
with the assets of, a 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 covered by a class or other applicable
exemption and (ii) in the case of a Plan subject to a substantially 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 2.13 Transfer Restrictions. Each Noteholder and Note
Owner of a Reset Rate Note shall be subject to the restrictions on transfer
thereof set forth in Appendix A-3 to this Indenture. Each Noteholder and Note
Owner of a Class A-5 Note shall be subject to the restrictions on transfer
thereof set forth in Appendix A-4 to this Indenture.

                                   ARTICLE III

                                    COVENANTS

                  Section 3.1 Payment to Noteholders and each Swap Counterparty.
The Issuer shall duly and punctually pay the principal and interest, if any,
with respect to the Notes in accordance with the terms of the Notes and this
Indenture and shall duly and punctually pay amounts, if any, owing to each Swap
Counterparty in accordance with the terms of this Indenture and the related Swap
Agreement. Without limiting the foregoing, the Issuer shall cause to be
distributed to Noteholders and each Swap Counterparty in accordance with the
Administration Agreement that portion of the amounts on deposit in the Trust
Accounts on a Distribution Date or with respect to any Swap Counterparty amounts
on deposit in the relevant Trust Accounts on the date such payment is due under
the related Swap Agreement, which the Noteholders and any Swap Counterparty are
entitled to receive pursuant to Sections 2.7 and 2.8 of the Administration
Agreement. Amounts properly withheld under the Code by any Person from a payment
to any Noteholder of interest and/or principal shall be considered as having
been paid by the Issuer to such Noteholder for all purposes of this Indenture.

                  Section 3.2 Maintenance of Office or Agency. The Issuer shall
maintain in the Borough of Manhattan, The City of New York and in Luxembourg, 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

                                      -11-

<PAGE>

Trust Office, and the Issuer hereby appoints the Indenture Trustee as its agent
to receive all such surrenders, notices and demands.

                  Section 3.3 Money for Payments to be Held in Trust. As
provided in Section 8.2(a) and (b), all payments of amounts due and payable with
respect to any Notes or any Swap Agreement that are to be made from amounts
distributed from the Collection Account or any other Trust Account pursuant to
Sections 2.7 and 2.8 of the Administration Agreement shall be made on behalf of
the Issuer by the Indenture Trustee or by another Paying Agent, and no amounts
so distributed from the Collection Account for payments of Notes or any Swap
Agreement shall be paid over to the Issuer except as provided in this Section.

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

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

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

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

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

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

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

                  The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, by Issuer
Order direct any Paying Agent to

                                      -12-

<PAGE>

pay to the Indenture Trustee all sums held in trust by such Paying Agent, such
sums to be held by the Indenture Trustee upon the same trusts as those upon
which the sums were held by such Paying Agent; and upon such payment by any
Paying Agent to the Indenture Trustee, such Paying Agent shall be released from
all further liability with respect to such money.

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

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

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

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

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

                  (iii)    enforce any of the Collateral; or

                                      -13-

<PAGE>

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

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

                  Section 3.6 Opinions as to Indenture Trust Estate. (a) On the
Closing Date, the Issuer shall furnish to the Indenture Trustee an Opinion of
Counsel either stating that, in the opinion of such counsel, such action has
been taken with respect to the recording and filing of this Indenture as is
necessary to perfect and make effective the lien and security interest of this
Indenture and reciting the details of such action, or stating that, in the
opinion of such counsel, no such action is necessary to make such lien and
security interest effective.

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

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

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

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

                                      -14-

<PAGE>

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

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

                  (e)      As promptly as possible after the giving of notice of
termination to the Servicer of the Servicer's rights and powers, pursuant to
Section 5.1 of the Servicing Agreement, or to the Administrator of the
Administrator's rights and powers, pursuant to Section 5.1 of the Administration
Agreement, the Issuer shall appoint a successor servicer (the "Successor
Servicer") or a successor administrator (the "Successor Administrator"),
respectively, and such Successor Servicer or Successor Administrator, as the
case may be, shall accept its appointment by a written assumption in a form
acceptable to the Indenture Trustee. In the event that a Successor Servicer or
Successor Administrator has not been appointed and accepted its appointment at
the time when the Servicer or Administrator, as the case may be, ceases to act
as Servicer or Administrator, respectively, the Indenture Trustee without
further action shall automatically be appointed the Successor Servicer or
Successor Administrator, as the case may be. The Indenture Trustee may resign as
the Successor Servicer or the Successor Administrator by giving written notice
of resignation to the Issuer and in such event will be released from such duties
and obligations, such release not to be effective until the date a new servicer
or a new administrator enters into an agreement with the Issuer as provided
below; provided, however, that nothing herein shall require or permit the
Indenture Trustee to act as Servicer, or otherwise service the Trust Student
Loans, in violation of the Higher Education Act. Upon delivery of any such
notice to the Issuer, the Issuer shall obtain a new servicer as the Successor
Servicer under the Servicing Agreement or a new administrator as the Successor
Administrator under the Administration Agreement, as the case may be. Any
Successor Servicer or Successor Administrator, other than the Indenture Trustee,
shall (i) be an established institution (A) that satisfies any requirements of
the Higher Education Act applicable to servicers and (B) whose regular business
includes the servicing or administration of student loans and (ii) enter into a
servicing agreement or an administration agreement, respectively, with the
Issuer having substantially the same provisions as the provisions of the
Servicing Agreement and the Administration Agreement, as applicable. If within
30 days after the delivery of the notice referred to above, the Issuer shall not
have obtained such a new servicer or new administrator, as the case may be, the
Indenture Trustee may appoint, or may petition a court of competent jurisdiction
to appoint, a Successor Servicer or Successor Administrator; provided, however,
that

                                      -15-

<PAGE>

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

                                      -16-

<PAGE>

other documents as the Indenture Trustee may deem necessary or appropriate in
the circumstances.

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

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

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

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

                  (iv)     enter into any amendment to the Interest Rate Cap
         Agreement or any Swap Agreement to cure any ambiguity in, or to correct
         or supplement any provision of the Interest Rate Cap Agreement or any
         Swap Agreement, unless the Issuer has determined, and the Indenture
         Trustee has agreed in writing at the written direction of the Issuer,
         that the amendment will not materially adversely affect the interests
         of the Noteholders and provided that the Issuer has provided reasonable
         notice to the Rating Agencies of such amendment and 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, 2004), an Officers' Certificate of the Issuer stating that:

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

                  (ii)     to the best of such Authorized Officers' knowledge,
         based on such review, the Issuer has complied with all conditions and
         covenants under this Indenture throughout

                                      -17-

<PAGE>

         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

the payment or redemption of which such moneys have been deposited with the

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

for the September 2013 Distribution Date or (b) the end of the first Collection
Period when the Pool Balance is equal to 10% or less of the initial Pool Balance
three Business Days prior to such Distribution Date (the "Trust Auction Date")
shall be offered for sale by the Indenture Trustee unless the Servicer has
exercised its option to purchase the Trust Estate as described in Section 6.1(a)
of the Administration Agreement with respect to such Distribution Date. The
Servicer will be deemed to have waived such option if it fails to notify the
Eligible Lender Trustee and the Indenture Trustee of its exercise thereof in
writing prior to the Indenture Trustee's acceptance of a bid to purchase such
Trust Student Loans; provided, however, that there shall be no such offer for
sale if the Indenture Trustee fails to provide notice to the Servicer in
accordance with this Section 4.4. The Indenture Trustee shall provide written
notice to the Servicer of any such offer for sale at least 5 Business Days in
advance of the Trust Auction Date. The Indenture Trustee shall permit the
Servicer or any of its Affiliates including Sallie Mae and the Servicer to offer
bids only if the Pool Balance as of the applicable Trust Auction Date is equal
to 10% or less of the Initial Pool Balance and such bid does not exceed the fair
market value of the Trust Student Loans as of the Trust Auction Date. If at
least two bids are received, the Indenture Trustee shall solicit and resolicit
new bids from all participating bidders until only one bid remains or the
remaining bidders decline to resubmit bids. The Indenture Trustee shall accept
the highest of such remaining bids if it is equal to or in excess of both the
Minimum Purchase Amount and the fair market value of such Trust Student Loans as
of the end of the Collection Period immediately

                                      -22-

<PAGE>

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 Initial Purchaser 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 paid at the time
set forth in Section 2.6 of the Administration Agreement and 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(a) of the Administration Agreement with respect to
each such future Distribution Date.

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

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

                                      -24-

<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 and any Cross-Currency Swap Counterparty by such appropriate
Proceedings as the Indenture Trustee shall deem most effective to protect and
enforce any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy or legal or equitable right vested
in the Indenture Trustee by this Indenture or by law.

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

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

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

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

                  (iv)     to file such proofs of claim and other papers or
         documents as may be necessary or advisable in order to have the claims
         of the Indenture Trustee, any Cross-Currency 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 and any
Cross-Currency Swap Counterparty to make payments to the Indenture Trustee, and,
in the event that the Indenture Trustee shall consent to the making of payments
directly to such Noteholders and any Cross-Currency Swap Counterparty to pay to
the Indenture Trustee such amounts as shall be sufficient to cover reasonable
compensation to the Indenture Trustee, each predecessor Indenture Trustee and
their respective agents, attorneys and counsel, and all other expenses and
liabilities incurred, and all advances made, by the Indenture Trustee and each
predecessor Indenture Trustee except as a result of negligence or bad faith.

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

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

                                      -26-

and their respective agents and attorneys, shall be for the ratable benefit of
the Noteholders, and after the Notes have been paid in full, and subject to the
provisions of Section 11.19, any Cross-Currency Swap Counterparty.

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

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

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

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

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

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

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

provided, however, that the Indenture Trustee may not sell or otherwise
liquidate the Indenture Trust Estate following an Event of Default, other than
an Event of Default described in Section 5.1(i) or (ii) with respect to the
Class A Notes, unless (A) the Noteholders of 100% of the Outstanding Amount of
the Class A Notes consent thereto, (B) the proceeds of such sale or liquidation
distributable to the Class A Noteholders are sufficient to discharge in full all
amounts then due and unpaid upon such Class A Notes for principal and interest
or (C) the Indenture Trustee determines that the Indenture Trust Estate will not
continue to provide sufficient funds for the payment of principal of and
interest on the Class A Notes as would have become due if the Class A Notes had
not been declared due and payable, and the Indenture Trustee obtains the consent
of Noteholders of 66-2/3% of the Outstanding Amount of the Class A Notes;
provided, further, that the Indenture Trustee may not sell or otherwise
liquidate the Indenture Trust Estate following an Event of Default, other than
an Event of Default described in Section 5.1(i) or (ii) with respect to the
Class A Notes, unless (D) the proceeds of such sale or liquidation

                                      -27-
<PAGE>

distributable to the Class B Noteholders plus the proceeds of the sale or
liquidation of the Trust Estate distributable to the Class B Noteholders are
sufficient to pay to the Class B Noteholders the Outstanding Amount of the Class
B Notes plus accrued and unpaid interest thereon or (E) after receipt of notice
from the Eligible Lender Trustee that the proceeds of such sale or liquidation
distributable to the Class B Noteholders plus the proceeds of the sale or
liquidation of the Trust Estate distributable to the Class B Noteholders would
not be sufficient to pay to the Class B Noteholders the outstanding principal
plus accrued and unpaid interest thereon, the Class B Noteholders of at least a
majority of the Outstanding Amount of the Class B Notes consent thereto. In
determining such sufficiency or insufficiency with respect to clauses (B), (C),
(D) and (E), the Indenture Trustee may, but need not, obtain and rely upon an
opinion of an Independent investment banking or accounting firm of national
reputation as to the feasibility of such proposed action and as to the
sufficiency of the Indenture Trust Estate and/or Trust Estate, as applicable,
for such purpose.

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

                  FIRST: to the applicable Noteholders of the Reset Rate Notes
then denominated in U.S. Dollars and bearing interest at a fixed rate, or if the
Reset Rate Notes are in Foreign Exchange Mode, to the related Cross-Currency
Swap Counterparty (for exchange into the applicable non-U.S. Dollar Currency)
the amount, if any, on deposit in the Accumulation Account for the Reset Rate
Notes (excluding any Investment Earnings thereon) in reduction of the
Outstanding Amount of the Reset Rate Notes until they are paid in full;

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

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

                  FOURTH: to the Administrator, any due and unpaid
Administration Fees;

                  FIFTH: pro rata, based on amounts due and owing:

                  A:       to the Class A Noteholders (other than the Reset Rate
                           Noteholders if a Swap Agreement is then in effect),
                           for amounts due and unpaid on the Class A Notes for
                           interest at the applicable Note Rate, ratably,
                           without preference or priority of any kind, according
                           to the amounts due and payable on the Class A Notes
                           for such interest;

                  B:       if a Swap Agreement is then in effect, to each Swap
                           Counterparty, the amount of any Swap Interest
                           Payments due and payable by the Issuer (other than as
                           paid to that Swap Counterparty under clause FIRST);
                           and

                                      -28-

<PAGE>

                  C:       if any Swap Agreement has been terminated, to the
                           related Swap Counterparty, the amount of any Swap
                           Termination Payments due to such Swap Counterparty
                           due to a Termination Event (as defined in the related
                           Swap Agreement) resulting from a payment default
                           under the related Swap Agreement by the Issuer, a
                           non-rescindable, non-waivable acceleration of the
                           Notes, or the bankruptcy or insolvency of the Issuer.

                  SIXTH:

                  A:       If the Reset Rate Notes are then in Foreign Exchange
                           Mode, pro rata (1) to the Class A Noteholders (other
                           than the holders of the Reset Rate Notes then in
                           Foreign Exchange Mode), ratably, an amount sufficient
                           to reduce the respective principal balance of those
                           Class A Notes to zero, and (2) to the related
                           Cross-Currency Swap Counterparty an amount sufficient
                           to reduce the U.S. Dollar Equivalent Principal Amount
                           of the Reset Rate Notes to zero; or

                  B        if the Reset Rate Notes are then denominated in U.S.
                           Dollars, pro rata to all of the Class A Noteholders,
                           ratably, an amount sufficient to reduce the
                           respective principal balances of the Class A Notes to
                           zero;

                  SEVENTH: to the Class B Noteholders for amounts due and unpaid
on the Class B Notes for interest at the Class B Note Rate;

                  EIGHTH: to the Class B Noteholders, an amount sufficient to
reduce the Outstanding Amount of the Class B Notes to zero;

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

                  TENTH: to any Swap Counterparties, pro rata, the amount of any
Swap Termination Payments due to such Swap Counterparties by the Issuer and not
payable in Clause FIFTH (C);

                  ELEVENTH: to the Remarketing Agents, any due and unpaid
Remarketing Fees payable by the Issuer to the extent not previously paid from
amounts on deposit in the Remarketing Fee Account;

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

                  THIRTEENTH: to the Interest Rate Cap Swap Counterparty, the
amount of any termination payment due to the Interest Rate Cap Swap Counterparty
by the Issuer under the Interest Rate Cap Agreement; and

                  FOURTEENTH: to the Excess Distribution Certificateholder, any
remaining funds.

                                      -29-

<PAGE>

                  In the event that the related Swap Agreements have terminated,
all payments by the Trust to the Noteholders of the Reset Rate Notes then in
Foreign Exchange Mode will be made in the applicable currency utilizing the
exchange rate set forth in the related Swap Agreement prior to its termination.

                  If a Cross-Currency Swap Agreement terminates, amounts that
would have otherwise been paid to the related Cross-Currency Swap Counterparty
under such Cross-Currency Swap Agreement (other than amounts payable as a
Termination Payment thereunder) will be used to make payments to the Reset Rate
Notes, in an amount in Pounds Sterling or any other applicable non-U.S. Dollar
currency equal to the payment that the related Cross-Currency Swap Counterparty
would have made. If this occurs, the Trust will exchange U.S. Dollars for Pounds
Sterling or any other applicable non-U.S. Dollar currency in order to make
distributions to the Reset Rate Notes.

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

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

                  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

                                      -30-

<PAGE>

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

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

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

                  Section 5.7 Unconditional Rights of Noteholders to Receive
Principal and Interest. Notwithstanding any other provisions in this Indenture,
each Noteholder shall have the right, which is absolute and unconditional, to
receive payment of the principal of and interest on its 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, any Swap
Counterparty or to the Noteholders is intended to be exclusive of any other
right or remedy, and every right and remedy shall, to the extent permitted by
law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

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

                                      -31-

<PAGE>

from time to time, and as often as may be deemed expedient, by the Indenture
Trustee, any Swap Counterparty or by the Noteholders, as the case may be.

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

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

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

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

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

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

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

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

                  Section 5.13 Undertaking for Costs. All parties to this
Indenture agree, and each Noteholder by such Noteholder's acceptance of any Note
shall be deemed to have agreed, that any court may in its discretion require, in
any suit for the enforcement of any right or remedy under this Indenture, or in
any suit against the Indenture Trustee for any action taken, suffered or omitted
by it as Indenture Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess

                                      -32-

<PAGE>

reasonable costs, including reasonable attorneys' fees, against any party
litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this
Section shall not apply to (a) any suit instituted by the Indenture Trustee, (b)
any suit instituted by any Noteholder, or group of Noteholders, in each case
holding in the aggregate more than 10% of the Outstanding Amount of the Notes or
(c) any suit Instituted by any Noteholder for the enforcement of the payment of
principal of or interest on any Note on or after the respective due dates
expressed in such Note and in this Indenture (or, in the case of redemption, on
or after the Redemption Date).

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

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

                  Section 5.16 Performance and Enforcement of Certain
Obligations. (a) Promptly following a request from the Indenture Trustee to do
so and at the Administrator's expense, the Issuer shall take all such lawful
action as the Indenture Trustee may request to compel or secure the performance
and observance by the Depositor, Sallie Mae, the Administrator and the Servicer,
as applicable, of each of their obligations to the Issuer, whether directly or
by assignment, under or in connection with the Sale Agreement, the Purchase
Agreement, the Administration Agreement and the Servicing Agreement,
respectively, in accordance with the terms thereof, and to exercise any and all
rights, remedies, powers and privileges lawfully available to the Issuer under
or in connection with the Sale Agreement, the Purchase Agreement, the
Administration Agreement and the Servicing Agreement, as the case may be, to the
extent and in the manner directed by the Indenture Trustee, including the
transmission of notices of default on the part of the Depositor, Sallie Mae, the
Administrator or the Servicer thereunder and the institution of legal or
administrative actions or proceedings to compel or secure performance by the
Depositor, Sallie Mae, the Administrator or the Servicer of each of their
obligations under the Sale Agreement, the Purchase Agreement, the Administration
Agreement and the Servicing Agreement, respectively.

                  (b)      If an Event of Default has occurred and is
continuing, the Indenture Trustee may, and at the written direction of the
Noteholders of 66-2/3% of the Outstanding Amount of the Notes shall, exercise
all rights, remedies, powers, privileges and claims of the

                                      -33-

<PAGE>

Issuer against the Depositor, Sallie Mae, the Administrator or the Servicer
under or in connection with the Sale Agreement, the Purchase Agreement, the
Administration Agreement and the Servicing Agreement, respectively, including
the right or power to take any action to compel or secure performance or
observance by the Depositor, Sallie Mae, the Administrator or the Servicer of
each of their obligations to the Issuer thereunder, whether directly or by
assignment, and to give any consent, request, notice, direction, approval,
extension or waiver under the Sale Agreement, the Purchase Agreement, the
Administration Agreement and the Servicing Agreement, respectively, and any
right of the Issuer to take such action shall be suspended.

                                   ARTICLE VI

                              THE INDENTURE TRUSTEE

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

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

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

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

<PAGE>

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

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

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

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

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

                  Section 6.2 Rights of Indenture Trustee. (a) The Indenture
Trustee may rely on any document believed by it to be genuine and to have been
signed or presented by the proper Person. The Indenture Trustee need not
investigate any fact or matter stated in such document.

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

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

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

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

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

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

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

                  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

                                      -36-

<PAGE>

and under the other Basic Documents. The Indenture Trustee shall notify the
Issuer and the Administrator promptly of any claim for which it may seek
indemnity. Failure by the Indenture Trustee to so notify the Issuer and the
Administrator shall not relieve the Issuer or the Administrator of its
obligations hereunder and under the other Basic Documents. The Issuer shall
cause the Administrator to defend the claim and the Administrator shall not be
liable for the legal fees and expenses of the Indenture Trustee after it has
assumed such defense; provided, however, that, in the event that there may be a
conflict between the positions of the Indenture Trustee and the Administrator in
conducting the defense of such claim, the Indenture Trustee shall be entitled to
separate counsel acceptable to it in its sole discretion the reasonable fees and
expenses of which shall be paid by the Administrator on behalf of the Issuer.
Neither the Issuer nor the Administrator need reimburse any expense or indemnify
against any loss, liability or expense incurred by the Indenture Trustee through
the Indenture Trustee's own willful misconduct, negligence or bad faith.

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

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

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

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

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

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

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

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

                                      -37-

<PAGE>

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
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

                                      -38-

<PAGE>

terms of eligibility as a successor trustee under Section 6.11 and no notice to
Noteholders of the appointment of any co-trustee or separate trustee shall be
required under Section 6.8 hereof.

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

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

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

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

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

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

                  Section 6.11 Eligibility; Disqualification. The Indenture
Trustee shall at all times satisfy the requirements of TIA Section 310(a), the
requirements of an "eligible lender" under 20 USC Section 1085(d) and the
requirements of Rule 3a-7(4)(i) of the General Rules and Regulations under the
Investment Company Act of 1940, as amended. The Indenture Trustee shall have a

                                      -39-

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

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

                                   ARTICLE VII

                         NOTEHOLDERS' LISTS AND REPORTS

                  Section 7.1 Issuer to Furnish Indenture Trustee Names and
Addresses of Noteholders. The Issuer will furnish or cause to be furnished to
the Indenture Trustee (a) not more than five days after the earlier of (i) each
Record Date and (ii) three months after the last Record Date, a list, in such
form as the Indenture Trustee may reasonably require, of the names and addresses
of the Noteholders as of such Record Date, (b) at such other times as the
Indenture Trustee may request in writing, within 30 days after receipt by the
Issuer of any such request, a list of similar form and content as of a date not
more than 10 days prior to the time such list is furnished; provided, however,
that so long as the Indenture Trustee is the Note Registrar, no such list shall
be required to be furnished.

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

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

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

                      ACCOUNTS, DISBURSEMENTS AND RELEASES

                  Section 8.1 Collection of Money. Except as otherwise expressly
provided herein, the Indenture Trustee may demand payment or delivery of, and
shall receive and collect, directly and without intervention or assistance of
any fiscal agent or other intermediary, all money and other property payable to
or receivable by the Indenture Trustee pursuant to this Indenture. The Indenture
Trustee shall apply all such money received by it on behalf of Noteholders and
any Swap Counterparty pursuant to the Administration Agreement as provided in
this Indenture. Except as otherwise expressly provided in this Indenture, if any
default occurs

                                      -41-

<PAGE>

in the making of any payment or performance under any agreement or instrument
that is part of the Indenture Trust Estate, the Indenture Trustee may take such
action as may be appropriate to enforce such payment or performance, including
the institution and prosecution of appropriate Proceedings. Any such action
shall be without prejudice to any right to claim a Default under this Indenture
and any right to proceed thereafter as provided in Article V.

                  Section 8.2 Trust Accounts. (a) On or prior to the Closing
Date, the Issuer shall cause the Administrator to establish and maintain, in the
name of the Indenture Trustee, for the benefit of the Noteholders and any Swap
Counterparty the Trust Accounts as provided in Section 2.3 of the Administration
Agreement.

                  (b)      On or before the Business Day immediately 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 required
deposits and distributions as provided in Sections 2.7 and 2.8 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 (except for the
Capitalized Interest Account, if any) shall be deposited by the Indenture
Trustee in the Collection Account, and any loss resulting from such investments
shall be charged to such Trust Account. All income or other gain from
investments of moneys deposited in the Capitalized Interest Account, if any,
shall be deposited by the Indenture Trustee in the Capitalized Interest Account,
and any loss resulting from such investments shall be charged to the Capitalized
Interest Account. The Issuer 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 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

                                      -42-

<PAGE>

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, subject to the interest therein of any Swap
Counterparty, release any remaining portion of the Indenture Trust Estate that
secured the Notes from the lien of this Indenture and release to the Issuer or
any other Person entitled thereto any funds then on deposit in the Trust
Accounts. The Indenture Trustee 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, and (iii) 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 or any Swap Counterparty in contravention of the provisions of this
Indenture; provided, however, that such Opinion of Counsel shall not be required
to express an opinion as to the fair value of the Indenture Trust Estate.
Counsel rendering any such opinion may rely, without independent investigation,
on the accuracy and validity of any certificate or other instrument delivered to
the Indenture Trustee in connection with any such action.

                  (ii)     to evidence the succession, in compliance with the

         and in the Notes contained;

                  (iii)    to add to the covenants of the Issuer, for the
         benefit of the Noteholders and, any Swap Counterparty, as applicable,
         or to surrender any right or power herein conferred upon the Issuer;

                  (iv)     to convey, transfer, assign, mortgage or pledge any

         shall be necessary to facilitate the administration of the trusts
         hereunder by more than one trustee, pursuant to the requirements of
         Article VI; or

                  (vii)    to modify, eliminate or add to the provisions of this
         Indenture to such extent as shall be necessary to effect the

         other provisions as may be expressly required by the TIA.

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

with prior notice to any Swap Counterparty and the Rating Agencies, enter into
an indenture or indentures supplemental hereto for the purpose of adding any
provisions to, or changing in any manner or eliminating any of the provisions
of, this Indenture or of modifying in any manner the rights of the Noteholders
or any Swap Counterparty under this Indenture; provided, however, that such
action shall not, as evidenced by an Opinion of Counsel, adversely affect in any
material respect the interests of any Noteholder or any Swap Counterparty.

                  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 any Swap Counterparty and the Rating
Agencies and with the consent of the Noteholders of not less than a majority of
the Outstanding Amount of the Notes, by Act of such Noteholders delivered to the
Issuer and the Indenture Trustee, enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to, or changing in
any manner or eliminating any of the provisions of, this Indenture or of
modifying in any manner the rights of the Noteholders under this Indenture;
provided, however, that no such supplemental indenture shall, without the
consent of the Noteholder of each Outstanding Note affected thereby:

                  (i)      change the date of payment of any installment of
         principal of or interest on any Note, or reduce the principal amount
         thereof, the interest rate thereon or the Redemption Price with respect
         thereto, change the provisions of this Indenture relating to the
         application of collections on, or the proceeds of the sale of, the
         Indenture Trust Estate to payment of principal of or interest on the
         Notes, or change any place of payment where, or the coin or currency in
         which, any Note or the interest thereon is payable (other than pursuant
         to the terms and conditions of the Reset Rate Notes or pursuant to the
         Reset Rate Note Procedures set forth in Appendix A-2 to this Indenture)
         or impair the right to institute suit for the enforcement of the
         provisions of this Indenture requiring the application of funds
         available therefor, as provided in Article V, to the payment of any
         such amount due on the Notes on or after the respective due dates
         thereof (or, in the case of redemption, on or after the Redemption
         Date);

                  (ii)     reduce the percentage of the Outstanding Amount of
         the Notes, the consent of the Noteholders of which is required for any

         additional provisions of this Indenture or the

                                      -45-

<PAGE>

         other Basic Documents cannot be modified or 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 interest or principal due on any Note on any Distribution Date
         (including the calculation of any of the individual components of such
         calculation) or to affect the rights of the Noteholders to the benefit

         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.

                  Promptly after the execution by the Issuer and the Indenture
Trustee of any supplemental indenture pursuant to this Section, the Indenture
Trustee shall mail to the 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

                                      -46-

<PAGE>

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

                  Section 9.6 Reference in Notes to Supplemental Indentures.
Notes authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article IX may, and if required by the Indenture
Trustee shall, bear a notation in form approved by the Indenture Trustee as to
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.

receipt of written notice from the Servicer pursuant to Section 6.1(b) 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(a) 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. 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

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

                  (ii)     the Redemption Price; and

                  (iii)    the place where such Notes are to be surrendered for
         payment of the Redemption Price (which shall be the office or agency of

                  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

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.

         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

                                      -48-

<PAGE>

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 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 3.11E of the Servicing Agreement,
         respectively, so long as the Issuer shall deliver to the Indenture
         Trustee every six months, commencing December 31, 2004, an Officers'
         Certificate of the Issuer stating that all the dispositions of
         Collateral

                                      -49-

<PAGE>

         described in clauses (A), (B) or (C) above that occurred during the
         immediately preceding six calendar months were in the ordinary course
         of the Issuer's business and that the proceeds thereof were applied in
         accordance with the Basic Documents.

                  Section 11.2 Form of Documents Delivered to Indenture Trustee.
In any case where several matters are required to be certified by, or covered by
an opinion of, any specified Person, it is not necessary that all such matters
be certified by, or covered by the opinion of, only one such Person, or that
they be so certified or covered by only one document, but one such Person may
certify or give an opinion with respect to some matters, and one or more other
such Persons as to other matters, and any such Person may certify or give an
opinion as to such matters in one or several documents.

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

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

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

                  Section 11.3 Acts of Noteholders. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken 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

                                      -50-

<PAGE>

signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and (subject to Section 6.1) conclusive in favor of
the Indenture Trustee and the Issuer, if made in the manner provided in this
Section.

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

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

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

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

                  (a)      The Indenture Trustee by any Noteholder, the
Servicer, the Administrator or by the Issuer shall be sufficient for every
purpose hereunder if made, given, furnished or filed in writing to or with the
Indenture Trustee at its Corporate Trust Office with a copy to: The Bank of New
York, 2 North LaSalle St., Suite 1020, Chicago, Illinois, 60602, Attention:
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 2003-12, 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: ABS 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 S&P, at the following address: 55 Water Street, New York, New York
10041-0003, Attention: Asset Backed Surveillance Department, 32nd Floor, and

Finance Group; or as to each of the foregoing, at such other address as shall be
designated by written notice to the other parties.

                  Notices to any Swap Counterparty will be sent to the addresses
set forth in the related Swap Agreement or the Interest Rate Cap Agreement,
respectively or such other addresses as may be designated by written notice to
the parties to this Indenture.

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

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

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

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

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

                  Section 11.7 Conflict with Trust Indenture Act. If any
provision hereof limits, qualifies or conflicts with another provision hereof
that is required to be included in this 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

                                      -52-

<PAGE>

this Indenture) are a part of and govern this Indenture, whether or not
physically contained herein.

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

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

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

                  Section 11.11 Benefits of Indenture. (a) Except as set forth
in paragraphs (b) and (c) below, nothing in this Indenture or in the Notes,
express or implied shall give to any person, other than the parties hereto and
their successors hereunder, the Noteholders, any other party secured hereunder,
and any other Person with an ownership interest in any part of the Indenture
Trust Estate, any benefit or any legal or equitable right, remedy or claim under
this Indenture.

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

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

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

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

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

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

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

                                      -54-

<PAGE>

Trustee may reasonably determine that such disclosure is consistent with its
obligations hereunder.

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

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

         meanings when used in any instrument governed hereby and in any
         certificate or other document made or delivered pursuant thereto unless
         otherwise defined therein.

                  (b)      As used herein, in any instrument governed hereby and
         in any certificate or other document made or delivered pursuant
         thereto, accounting terms not defined in this Appendix or in any such

         other document, to the extent not defined, shall have the respective
         meanings given to them under generally accepted accounting principles
         as in effect on the date of such instrument. To the extent that the

         of similar import when used in an instrument refer to such instrument
         as a whole and not to any particular provision or subdivision thereof;
         references in an instrument to "Article," "Section" or another

         referred to below or in any agreement or instrument that is governed by

         time to time amended, modified or supplemented, including (in the case
         of agreements or instruments) by assignment, assumption, waiver or
         consent and (in the case of statutes) by succession of comparable
         successor statutes and includes (in the case of agreements or
         instruments) references to all attachments thereto and instruments
         incorporated therein. References to a Person are also to its permitted

results of the auctions of 91-day Treasury Bills cease to be published or
reported as provided above, or that no 91-day Treasury Bill auction is held in a
particular week, then the 91-day Treasury Bill Rate in effect as a result of the
last such publication or report will remain in effect until such time, if any,

or reported or such auction is held, as the case may be. The 91-day Treasury
Bill Rate will be subject to a Lock-In Period of six Business Days.

and including March 14, 2004; provided that if more than one Interest Rate
Change Date occurs for the Reset Rate Notes bearing a floating rate of interest
within any given Accrual Period, the rate of interest for the entire Accrual
Period shall be as specified in the relevant Remarketing Terms Notice; and (ii)
the Reset Rate Notes if they then bear a fixed rate of interest and (x) are
denominated in U.S. Dollars, the period from and including the 15th day of the

                  Accrual Period is equal to or shorter than the Determination
                  Period during which such Accrual Period ends, the number of

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

                           RESET RATE NOTE PROCEDURES

                  Section 1. Definitions. All terms which are defined in
Appendix A-1 shall have the same meanings in this Appendix A-2.

                  Section 2. Interest Rates; Principal Payments (a) The Reset
Rate Notes will bear interest for each Reset Period at the rate set forth on
Schedule A attached to the Reset Rate Note as determined in accordance with
Section 2(b) below; provided, that for the initial Reset Period, the Reset Rate
Notes will bear interest from the Closing Date through and including the Initial
Reset Date at the rate set forth in the first sentence of the definitions of
"Class A-6 Rate". Interest on the Reset Rate Notes shall be payable by the trust
with respect to each Distribution Date at the priority level set forth in
Section 2.8(d) of the Administration Agreement; provided, that if interest due
to the Reset Rate Notes is payable through a Swap Agreement, the related Swap
Interest Payments will be payable by the Trust to the related Swap Counterparty,
and by the Swap Counterparty to the Trust (for payment to the Reset Rate
Noteholders), as described in Section 10 below.

                  (b) After the initial Reset Period, the Reset Rate Notes may
be reset to bear either a fixed or floating rate of interest at the option of
the Remarketing Agents, in consultation with the Administrator. The interest
rate of the Reset Rate Notes will be reset as of each Reset Date as determined
by (i) the Remarketing Agents, in consultation with the Administrator, with
respect to (A) the length of the Reset Period, (B) whether the rate is fixed or
floating and (x) if floating, the applicable Index, or (y) if fixed, the
applicable pricing benchmark, (C) the applicable Day Count Basis, (D) the
applicable currency denomination, i.e., U.S. Dollars, Euros, Pounds Sterling or
another non-U.S. Dollar currency, (E) if in Foreign Exchange Mode, the
applicable Distribution Dates on which interest will be paid to the Reset Rate
Noteholders, (F) the applicable Interest Rate Determination Dates within each
Accrual Period, (G) the interval between Interest Rate Change Dates during each
Accrual Period and (H) if applicable, the All Hold Rate, and (ii) the
Remarketing Agents (in their sole determination) with respect to the setting of
the (A) fixed rate of interest or (B) Spread to the chosen Index, as applicable.

                  (c) In the event that the Reset Rate Notes are reset (i) to
bear (or continue to bear) interest at a floating rate, (ii) to bear (or
continue to bear) a fixed rate of interest and/or (iii) to be denominated (or
continue to be denominated) in a currency other than U.S. Dollars, and the
Remarketing Agents, in consultation with the Administrator determine that it
would be in the best interest of the Trust based on existing market conditions
to enter into one or more Swap Agreements, the Administrator will be responsible
for arranging, on behalf of the Trust, one or more Swap Agreements to hedge the
basis risk and/or currency exchange risk (as applicable) and, together with the
Remarketing Agents, for selecting the Swap Counterparties thereto in accordance
with the procedures set forth in Section 10(b) below. The Reset Rate Notes will
not be reset (or continue) to bear interest at a floating rate that is not based
on LIBOR or a Commercial Paper Rate, at a fixed rate or to be denominated in a
currency other than U.S. Dollars unless one or more Swap Agreements are entered
into as of the related Reset Date that

                                 Appendix A-2-1

<PAGE>

results in the Rating Agency Condition being satisfied. In connection with each
Swap Agreement, the Remarketing Agents shall solicit bids from Eligible Swap
Counterparties in accordance with the procedures set forth in Section 10(d)
below.

                  (d) The Reset Rate Notes that bear interest at (i) a floating
rate shall be entitled to receive payments of principal in reduction of its
Outstanding Amount on each Distribution Date at the priority level set forth in
Section 2.8(f) of the Administration Agreement and (ii) a fixed rate shall be
entitled to receive allocations of principal at the priority level set forth in
Section 2.8(f) of the Administration Agreement on each Distribution Date,
provided, however, that such amounts referred to in this clause (ii) shall not
be paid in reduction of the Outstanding Amount of the Reset Rate Notes; instead
all such amounts shall be deposited into the Accumulation Account for payment to
the Reset Rate Noteholders or Swap Counterparty, as applicable, on or about the
next Reset Date as set forth in Section 11(a) below.

                  Section 3. End of Reset Period Notice. (a) Unless the holder
of the Call Option has delivered the related Call Option Notice, the
Administrator, not less than fifteen nor more than thirty calendar days prior to
any Remarketing Terms Determination Date, will (i) give written notice
(including facsimile or other electronic transmission, if permitted pursuant to
the recipient's standard procedures) to the applicable Clearing Agencies and the
Luxembourg Stock Exchange (for so long as the Reset Rate Notes are listed on
such exchange), with a copy to the Indenture Trustee, notifying them of the
upcoming Reset Date and stating whether tender is deemed mandatory or optional
for the Reset Rate Notes on the Reset Date (the Initial Reset Date Notice"),
(ii) request that each Clearing Agency notify its participants of (1) the
contents of the Initial Reset Date Notice, (2) the Remarketing Terms Notice to
be given on the Remarketing Terms Determination Date pursuant to Section 4(d)
below, (3) the Spread Determination Notice to be given on the Spread
Determination Date pursuant to Section 9(e) below, and (4) if applicable, the
procedures concerning the timely delivery of a Hold Notice pursuant to Section 8
below that must be followed if any beneficial owner of a Reset Rate Note wishes
to retain its Reset Rate Notes. For so long as the Reset Rate Notes are listed
on the Luxembourg Stock Exchange, a copy of such notices will be sent to the
Luxembourg Stock Exchange and each of the Remarketing Terms Notice and the
Spread Determination Notice will also be published in a leading newspaper having
general circulation in Luxembourg (which is expected to be The Luxemburger Wort)
and (iii) initiate discussions with representatives of the Luxembourg Stock
Exchange regarding an addendum to the Offering Memorandum dated November 14,
2003, if required by Section 7(f)(i) of the Remarketing Agreement.

                  (b) The Administrator will also include in the Initial Reset
Date Notice the names and contact information of the Luxembourg listing agent,
if applicable, and any Remarketing Agents confirmed or appointed by the
Administrator, or if no Remarketing Agents have then been so chosen, the
Administrator will provide adequate contact information for Reset Rate
Noteholders to receive information regarding the upcoming Reset Date.

                  (c) If the related Clearing Agency or its respective nominee,
as applicable, is no longer the holder of record of the Reset Rate Notes, the
Administrator, or the Remarketing Agents on its behalf, will send the Reset Rate
Noteholders, with a copy to the Indenture Trustee and the Luxembourg listing
agent, as applicable, the required notices setting forth the information in
Sections 3(a) and 3(b) above not less than fifteen nor more than thirty calendar

                                 Appendix A-2-2

<PAGE>

days prior to any Remarketing Terms Determination Date. In addition, in the
event that Definitive Notes evidencing an interest in the Reset Rate Notes are
issued, the Administrator shall cause the Note Registrar to provide to the
relevant Reset Rate Noteholders and the Luxembourg listing agent, as applicable,
any additional procedures applicable to such Reset Rate Notes while in
definitive form.

                  Section 4. Remarketing Terms Determination Date. (a) Subject
to the provisions of the Remarketing Agreement, prior to the Remarketing Terms
Determination Date, and unless the holder of the Call Option has delivered the
Call Option Notice, the Administrator shall re-affirm the capability of the
initial Remarketing Agents to perform under the Remarketing Agreement, and/or
enter into new remarketing agreements with other or additional remarketing
agents, who shall function as the Remarketing Agents with respect to the Reset
Date. On each Remarketing Terms Determination Date, the Trust, the Administrator
and the Remarketing Agents will enter into a Remarketing Agency Agreement for
the remarketing of the Reset Rate Notes.

                  (b) If the Remarketing Agents, in consultation with the
Administrator, determine prior to the Remarketing Terms Determination Date that
any Cross-Currency Swap Agreements or Reset Date Currency Swap Agreements
required pursuant to Section 2(c)(iii) above will not be obtainable on the Reset
Date, the Reset Rate Notes must be denominated in U.S. Dollars during the next
Reset Period.

                  (c) Unless the holder of the Call Option has delivered
the Call Option Notice, on or prior to the Remarketing Terms Determination Date
the Remarketing Agents will notify the Reset Rate Noteholders whether tender is
deemed mandatory or optional and, in consultation with the Administrator, will
establish the following terms for the Reset Rate Notes to be applicable during
the immediately following Reset Period:

                  (i)     the expected weighted average life of the Reset Rate
         Notes, based on prepayment and other assumptions customary for
         comparable securities;

                  (ii)    the name and contact information of the Remarketing
         Agents;

                  (iii)   the next Reset Date and length of such Reset Period;

                  (iv)    the interest rate mode (i.e., fixed rate or floating
         rate);

                  (v)     the currency denomination;

                  (vi)    the applicable minimum denominations and additional
         increments for the Reset Rate Notes;

                  (vii)   if in Foreign Exchange Mode, the identities of the
         Eligible Swap Counterparties from which bids will be solicited and the
         identity, if known, of the proposed Swap Agent for each related
         Eligible Swap Counterparty;

                                 Appendix A-2-3

<PAGE>

                  (viii)  if in Foreign Exchange Mode, the applicable
         Distribution Dates on which interest and principal will be paid to the
         Reset Rate Noteholders;

                  (ix)    if in floating rate mode, the applicable Index;

                  (x)     if in floating rate mode, the interval between
         Interest Rate Change Dates;

                  (xi)    if in floating rate mode, the applicable Interest Rate
         Determination Date;

                  (xii)   if in fixed rate mode, the applicable fixed rate
         pricing benchmark;

                  (xiii)  if in fixed rate mode, the identities of the Eligible
         Swap Counterparties from which bids will be solicited;

                  (xiv)   if in floating rate mode, whether there will be a
         related Swap Agreement and, if so, the identities of the Eligible Swap
         Counterparties from which bids will be solicited;

                  (xv)    the applicable Day Count Basis;

                  (xvi)   the All Hold Rate, if applicable;

                  (xvii)  if Definitive Notes are to be issued, the procedures
         for delivery and exchange of Definitive Notes and for dealing with lost

                  (xviii) any other relevant terms incidental to the foregoing
         (other than the Spread or fixed rate of interest, as applicable) for
         the next Reset Period;

provided, that any interest rate mode, other than a floating rate based on LIBOR
or a Commercial Paper Rate, will require that the Rating Agency Condition be
satisfied prior to the delivery of the Remarketing Terms Notice.

                  (d) The Remarketing Agents will communicate all of the
information established in Section 4(c) above in the Remarketing Terms Notice
required to be given in writing (including facsimile or other electronic
transmission if in accordance with each Clearing Agency's standard procedures)
to each Clearing Agency (and the Luxembourg Stock Exchange if the Reset Rate
Notes are then listed on such exchange) or the Reset Rate Noteholders if
Definitive Notes have been issued, as applicable, the Indenture Trustee and the
Rating Agencies on the Remarketing Terms Determination Date.

                  (e) In addition, prior to the Remarketing Terms Determination
Date, the Administrator shall cause the Schedule Replacement Order with respect
to the Reset Rate Notes to be delivered to the Indenture Trustee, the Clearing
Agencies and, if the Reset Rate Notes are then listed on the Luxembourg Stock
Exchange, the Luxembourg listing agent.

                                 Appendix A-2-4

                  Section 5. All Hold Rate. (a) On each Remarketing Terms
Determination Date for the Reset Rate Notes which are denominated in U.S.
Dollars during both the then-current Reset Period and the immediately following
Reset Period, the Remarketing Agents, in consultation with the Administrator,
will establish the All Hold Rate for the Reset Rate Notes. With respect to the
Reset Rate Notes that are either in Foreign Exchange Mode during the
then-current Reset Period or will be reset into Foreign Exchange Mode on the
immediately following Reset Date, all Reset Rate Noteholders will be deemed to
have tendered their Notes on the Reset Date, regardless of any desire by such
Reset Rate Noteholders to retain their ownership thereof, and no All Hold Rate
will be applicable.

                  (b) The All Hold Rate will only be applicable if 100% of
the Reset Rate Noteholders deliver timely Hold Notices wherein they elect to
hold their Reset Rate Notes for the next Reset Period. If applicable, the
interest rate for the Reset Rate Notes during the immediately following Reset
Period will not be less than the All Hold Rate. If the rate of interest using
the Spread or fixed rate of interest established on the Spread Determination
Date is higher than the All Hold Rate, then upon a successful remarketing of the
Reset Rate Notes, all Reset Rate Noteholders who delivered a Hold Notice
agreeing to be subject to the All Hold Rate instead will be entitled to the
higher rate of interest during the immediately following Reset Period.

                  Section 6. Failed remarketing. (a) with respect to each Reset
Date for which the holder of the Call Option does not deliver the Call Option
Notice, a Failed Remarketing will be declared by the Remarketing Agents and the
provisions of this Section 6 will apply if any of the conditions set forth in
the definition of "Failed Remarketing" are applicable. In order to prevent the
declaration of a Failed Remarketing, the Remarketing Agents will have the
option, but not the obligation, to purchase any Reset Rate Notes tendered that
they are not otherwise able to remarket or with respect to which a committed
purchaser defaults on their purchase obligations.

                  (b) At any time a Failed Remarketing is declared: (i) all
Reset Rate Notes will be retained by the Reset Rate Noteholders on the related
Reset Date, regardless of any deemed mandatory or voluntary tenders made to the
Remarketing Agents, (ii) the Failed Remarketing Rate for Reset Rate Notes will
apply for the related Reset Period and (iii) a Reset Period of three months will
be established. In addition, if the Reset Rates Notes are in Foreign Exchange
Mode at the time a Failed Remarketing is declared, the provisions of Sections
10(a)(i) and (ii) shall also apply.

                  (c) If there is a Failed Remarketing of the Reset Rate
Notes, the Reset Rate Noteholders shall not be entitled to exercise any remedies
as a result of the failure of the Reset Rate Notes to be remarketed on the Reset
Date.

                  Section 7. Call Option. (a) With respect to each Reset Date,
the Depositor, as the initial holder of the Excess Distribution Certificate, is
hereby granted the Call Option for the purchase of not less than 100% of the
Reset Rate Notes, exercisable at a price equal to 100% of the Outstanding Amount
of the Reset Rate Notes, less all amounts distributed to the Reset Rate
Noteholders as a payment of principal with respect to the Distribution Date,
plus any accrued and unpaid interest not paid by the Trust with respect to the
applicable Reset Date.

                  (b) The Depositor, as the initial holder of the Excess
Distribution Certificate, effective as of the Closing Date, hereby transfers all
of its right title and interest in and to the Call Option to SLM Education
Credit Management Corporation, which upon receipt thereof will dividend all of
its right, title and interest in and to the Call Option to SLM Corporation, and
in acceptance of such transfer SLM Corporation also hereby agrees to abide by
all terms and conditions hereunder with respect to the Call Option as set forth
in these Reset Rate Note Procedures.

                  (c) SLM Corporation may further transfer ownership of the
Call Option at any time to one of its Affiliates, provided that such permitted
transferee has at no time in the past owned, and is not obligated under either
the Purchase Agreement or the Sale Agreement to transfer, an interest in any of
the Trust Student Loans.

                  (d) The Call Option may be exercised with respect to the
Reset Rate Notes at any time on or prior to the determination of the related
Spread or fixed rate or the declaration of a Failed Remarketing, as applicable,
on the related Spread Determination Date by delivery of a Call Option Notice;
provided that the Call Option may not be exercised before the day following the
last Distribution Date immediately preceding the next applicable Reset Date. In
addition, for so long as the Reset Rate Notes are listed on the Luxembourg Stock
Exchange, the holder of the Call Option shall cause a notice of the exercise of
the Call Option to be published in a leading newspaper having general
circulation in Luxembourg (which is expected to be The Luxemburger Wort). Once
written notice of the exercise of the Call Option is given, such exercise may
not be rescinded.

                  (e) All amounts due and owing to the Reset Rate
Noteholders shall be remitted on or before the related Reset Date by the holder
of the Call Option in accordance with the standard procedures established by the
Clearing Agencies for transfer of securities to ensure timely payment of
principal to the Reset Rate Noteholders on the Reset Date.

                  (f) In the event that the Call Option is exercised with
respect to the Reset Rate Notes if they are then in Foreign Exchange Mode, the
holder of the Call Option shall deliver the U.S. Dollar Equivalent Principal
Amount remaining after all payments of principal are made with respect to the
related Distribution Date, and interest (if applicable) owing to the Reset Rate
Noteholders to the Remarketing Agents for delivery to the related Swap Agents
for delivery to the Swap Counterparties to the related Reset Date Currency Swap
Agreements, who shall exchange such amount into the applicable currency for
delivery to the Reset Rate Noteholders; provided, however, that if there are no
such Reset Date Currency Swap Agreements then in effect, the holder of the Call
Option shall remit all amounts due and owing to the Remarketing Agents for
delivery to the Reset Rate Noteholders in the applicable currency on or before
the Reset Date in accordance with the standard procedures established by the
related Clearing

                                 Appendix A-2-6

<PAGE>

Agencies for transfer of securities to ensure timely payment of principal to the
Reset Rate Noteholders on the Reset Date.

                  (g) If the Call Option is exercised with respect to the Reset
Rate Notes, (i) the interest rate on the Reset Rate Notes will be the Call Rate,
(ii) the Reset Rate Notes will be denominated in U.S. Dollars and (iii) a Reset
Period of three months will be established. At the end of such three month Reset
Period, the holder of the Call Option may either remarket the Reset Rate Notes
pursuant to the remarketing procedures set forth herein and in the Remarketing
Agreement, or retain the Reset Rate Notes for one or more successive three-month
Reset Periods at the then-current Call Rate. In the event the holder of the Call
Option chooses to remarket the Reset Rate Notes, such holder shall be solely
responsible for all costs and expenses relating to the preparation of any new
offering document and any other related costs and expenses associated with such
remarketing, other than the fees of the Remarketing Agents, as more fully set
forth in Section 3 of the Remarketing Agreement.

                  (h) Other than in connection with the exercise of a Call
Option, neither SLM Corporation, Sallie Mae, the Trust or any of their
Affiliates shall have the ability to purchase any Reset Rate Notes tendered to
the Remarketing Agents.

                  Section 8. Hold Notice. If the Reset Rate Notes are
denominated in U.S. Dollars during both the then-current Reset Period and the
immediately following Reset Period, the Reset Rate Noteholders will have the
option to deliver a Hold Notice to any Remarketing Agent setting forth their
desire to hold their Reset Rate Notes for the next Reset Period at a rate of
interest not less than the All Hold Rate and on the terms set forth in the
related Remarketing Terms Notice, at any time on or after the Remarketing Terms
Determination Date until the Notice Date. Such Hold Notice may be delivered as
an oral statement to a Remarketing Agent, if subsequently confirmed in writing
within 24 hours, which confirmation may be in the form of an e-mail if timely
received by the Remarketing Agent. If a Reset Rate Noteholder does not timely
deliver a Hold Notice to a Remarketing Agent (such Hold Notice not to be
considered delivered until actually received by such Remarketing Agent), that
Reset Rate Noteholder will be deemed to have tendered for remarketing 100% of
the Outstanding Amount of the Reset Rate Notes. Any duly delivered Hold Notice
will be irrevocable, but will be subject to a mandatory tender of the Reset Rate
Notes pursuant to any exercise of the Call Option. All of the Reset Rate Notes,
whether tendered or not, will bear interest during any Reset Period on the same
terms.

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

                  (b) If pursuant to the Remarketing Terms Notice, the
Remarketing Agents, in consultation with the Administrator, have determined that
the Reset Rate Notes are to be reset to bear a fixed rate of interest, then the
applicable fixed rate of interest for the corresponding Reset Period will be
determined on the Spread Determination Date by adding (i) the applicable spread
as determined by the Remarketing Agents on the Spread Determination Date and
(ii) the yield to maturity on the Spread Determination Date of the applicable
fixed rate pricing benchmark, selected by the Remarketing Agents, as having an
expected weighted average life based on a

                                 Appendix A-2-7

<PAGE>

scheduled maturity at the next Reset Date, which would be used in accordance
with customary financial practice in pricing new issues of asset-backed
securities of comparable average life; provided that such fixed rate of interest
will in no event be lower than the related All Hold Rate, if applicable. The
Remarketing Agents shall determine the applicable fixed rate of interest for the
Reset Rate Notes (by reference to the applicable fixed rate pricing benchmark
plus or minus the spread determined on the Remarketing Terms Determination Date)
on each Spread Determination Date irrespective of whether no remarketing will
occur as the result of the application of the All Hold Rate, if applicable. In
addition, on the related Spread Determination Date, the Remarketing Agents, in
consultation with the Administrator, shall determine the Supplemental Interest
Account Deposit Amount, if any, for the Reset Rate Notes.

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

                  (d) If required pursuant to Section 2(c) above, on the related
Reset Date the Trust shall enter into either (i) one or more Cross-Currency Swap
Agreements, if the Reset Rate Notes are to be reset in Foreign Exchange Mode, or
(ii) one or more Interest Rate Swap Agreements if the Reset Rate Notes are to be
reset in U.S. Dollars and to bear interest at a fixed rate or at a floating rate
other than one based on LIBOR or a Commercial Paper Rate, with an Eligible Swap
Counterparty. In addition, if the Reset Rate Notes are to be reset in Foreign
Exchange Mode, on the Reset Date the Remarketing Agents shall cause at least one
Swap Agent to enter into one or more Reset Date Currency Swap Agreements with
one or more Eligible Swap Counterparties.

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

                                 Appendix A-2-8

<PAGE>

addition, if required for the immediately following Reset Period, on or before
the related Spread Determination Date the Administrator will arrange for new or
additional securities identification codes to be obtained as required.

                  Section 10. Swap Agreements: (a) If the Reset Rate Notes are
to be reset in Foreign Exchange Mode, on the Reset Date, the Administrator will
enter into (not in its individual capacity, but solely as Administrator on
behalf of the Trust) or will instruct the Eligible Lender Trustee to enter into
(not in its individual capacity, but solely as Eligible Lender Trustee) one or
more Cross-Currency Swap Agreements for the Reset Period.

                  (i) Each Cross-Currency Swap Counterparty (including, without
limitation, the Initial Cross-Currency Swap Counterparty) which is party to a
related Cross-Currency Swap Agreement will be entitled to receive with respect
to each Distribution Date, (x) an interest rate of Three-Month LIBOR, plus or
minus a spread, as determined from the bidding process described in Section
10(d) below (other than as may be interpolated for an initial or final
calculation period under that Cross-Currency Swap Agreement), multiplied by the
U.S. Dollar Equivalent Principal Amount of the Reset Rate Notes, and multiplied
by a fraction determined by the number of days in the applicable Accrual Period
and the applicable Day Count Basis, (y) all payments of principal in U.S.
Dollars that are allocated to the Reset Rate Notes; provided that if the Reset
Rate Notes bear a fixed rate of interest, all principal payments allocated to
the Reset Rate Notes on any Distribution Date will be deposited into the
Accumulation Account and paid to the related Swap Counterparties on or about the
next Reset Date as set forth in the related Cross-Currency Swap Agreements
(including all sums required to be deposited therein on the Reset Date), but
excluding all Investment Earnings thereon. With respect to the Initial
Cross-Currency Swap Agreement, the Initial Swap Counterparty also shall be
entitled to receive on the Closing Date, all applicable non-U.S. Dollar currency
proceeds received by the Trust from purchasers of the Reset Rate Notes (which
shall be net of any underwriting commission or discount owing to the initial
purchasers of such Notes).

                  (ii) In addition, each related Cross-Currency Swap
Counterparty will be obligated to pay to the Trust (for payment to the Reset
Rate Noteholders, if applicable): (x) on the Closing Date and with respect to
the Initial Cross-Currency Swap Agreement only, the U.S. Dollar Equivalent
Principal Amount of the applicable non-U.S. Dollar currency paid to such
Cross-Currency Swap Counterparty by the Trust; (y) with respect to each
applicable Distribution Date, (A) their applicable percentage of the applicable
rate of interest on the Reset Rate Notes multiplied by the U.S. Dollar
Equivalent Principal Amount of the Reset Rate Notes and multiplied by a fraction
determined by the number of days in the applicable Accrual Period and the
applicable Day Count Basis, and (B) the applicable non-U.S. Dollar currency
equivalent of the U.S. Dollars such Swap Counterparty concurrently receives from
the Trust as a payment of principal allocated to the Reset Rate Noteholders
(including, on the Maturity Date for the Reset Rate Notes, if a Cross-Currency
Swap Agreement is then in effect, the remaining Outstanding Amount of the Reset
Rate Notes) but only to the extent that the required U.S. Dollar Equivalent
Principal Amount is received from the Trust on such date, at an exchange rate to
be set on the effective date of and set forth in the related Cross-Currency Swap
Agreement; and (z) on the second Business Day following a Distribution Date that
is also a Reset Date (other than for any Reset Period following a Reset Date
upon which a Failed Remarketing has occurred, up to and including the Reset Date
resulting in a successful remarketing or an exercise of the Call Option)

                                 Appendix A-2-9

their applicable percentage of interest at the interest rate from and including
the Reset Date to, but excluding, the second Business Day following such Reset
Date. For any Reset Period following a Reset Date upon which a Failed
Remarketing has occurred, up to any including the Reset Date resulting in a
successful remarketing or an exercise of the Call Option for the Reset Rate
Notes, payments of interest and principal to the Reset Rate Noteholders will be
made on the second Business Day following the Reset Date without the payment of
any additional interest.

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

                  (i) On the effective date of any Reset Date Currency Swap
Agreement (except with respect to the Initial Reset Date Currency Swap
Agreements), (A) the Remarketing Agents will deliver to each Swap Agent, for
further delivery to the related Swap Counterparty, its percentage of all
secondary trade sale proceeds received from purchasers of the Reset Rate Notes
in the applicable non-U.S. Dollar currency, and (B) in return, the related Swap
Counterparty will deliver to the related Swap Agent, for delivery to the
Remarketing Agents, the U.S. Dollar equivalent of such sale proceeds using the
conversion rate established on the applicable effective date. Upon receipt, the
Remarketing Agents will then deliver such sums either (1) to the tendering Reset
Rate Noteholders, if the Reset Rate Notes were denominated in U.S. Dollars
immediately prior to such Reset Date, as payment in full of the Outstanding
Amount of the Reset Rate Notes, or (2) if the Reset Rate Notes were in Foreign
Exchange Mode immediately prior to such Reset Date, to the related Swap Agent
for the Reset Date Currency Swap Agreement in effect for the Reset Period ending
on such Reset Date for the purposes described in subparagraph (ii) below.

                  (ii) On the Reset Date corresponding to the successful
remarketing of the Reset Rate Notes, (A) each Swap Agent for the related Reset
Date Currency Swap Agreement in effect for the Reset Period ending on such Reset
Date will be obligated to deliver to the related Swap Counterparty for the
related Reset Date Currency Swap Agreement in effect for the Reset Period ending
on such Reset Date, its percentage of all U.S. Dollar secondary trade sale
proceeds received from the Remarketing Agents that the Remarketing Agents either
received directly from the purchasers of such Reset Rate Notes (if remarketed in
U.S. Dollars) or from such Swap Agent with respect to the related Reset Date
Currency Swap Agreement commencing on such Reset Date (if remarketed in Foreign
Exchange Mode, as described in subparagraph (i) above), and (B) in return, the
related Swap Counterparty for the related Reset Date Currency Swap Agreement in
effect for the Reset Period ending on such Reset Date will deliver to the
related Swap Agent for the related Reset Date Currency Swap Agreement in effect
for the Reset Period ending on such Reset Date, for delivery to the Remarketing
Agents, the non-U.S. Dollar currency equivalent of such secondary trade sale
proceeds, using the exchange rate set forth in such Reset Date Currency Swap
Agreement (or in the case of the Initial Reset Date Currency Swap Agreement, the
Closing Date). The Remarketing Agents will then deliver such non-U.S. Dollar
currency amounts to the tendering Reset Rate Noteholders, as payment in full of
the Outstanding

                                 Appendix A-2-10

<PAGE>

Amount of their Reset Rate Notes, and the Reset Date Currency Swap Agreement
effective during the previous Reset Period will terminate in accordance with its
terms.

                  (c) If the Reset Rate Notes are to be reset in U.S. Dollars,
and a Swap Agreement is required pursuant to Sections 2(c) and 9(d) above, then
the Administrator will enter into (not in its individual capacity, but solely as
Administrator on behalf of the Trust) or will instruct the Eligible Lender
Trustee to enter into (not in its individual capacity, but solely as Eligible
Lender Trustee), one or more Interest Rate Swap Agreements for the next Reset
Period to facilitate the Trust's ability to pay applicable interest at the
related interest rate.

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

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

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

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

                  (f) Each Cross-Currency Swap Agreement and each Reset Date
Currency Swap Agreement will terminate at the earliest to occur of (i) the next
succeeding Reset Date for which there is a successful remarketing, (ii) the
Reset Date for which the Call Option is

                                 Appendix A-2-11

<PAGE>

exercised, (iii) the Distribution Date on which the Outstanding Amount of the
Reset Rate Notes are reduced to zero (including as the result of the optional
purchase of the remaining Trust Student Loans by the Servicer or an auction of
the Trust Student Loans by the Indenture Trustee) or (iv) the Maturity Date of
the Reset Rate Notes. No Cross-Currency Swap Agreement or Reset Date Currency
Swap Agreement will terminate solely due to the declaration of a Failed
Remarketing. Each Interest Rate Swap Agreement will terminate on the earliest to
occur of the next Reset Date, or the occurrence of an event specified in clause
(ii), (iii) or (iv) above.

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

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

                  (b) On each Reset Date, if the Reset Rate Notes bore interest
at a fixed rate during the preceding Reset Period (including without limitation,
on the Initial Reset Date), all sums, if any, then on deposit in the
Accumulation Account, including any allocation of principal made on the same
date, but less any Investment Earnings, will be distributed by the Indenture
Trustee, at the direction of the Administrator, as set forth in Section 2.8 of
the Administration Agreement, (x) to the holders of the Reset Rate Notes, as of
the Record Date, or (y) if the Reset Rate Notes are in Foreign Exchange Mode
(including during the initial Reset Period), to the related Cross-Currency Swap
Counterparty or Counterparties for the benefit of such Reset Rate Noteholders as
of the Record Date pursuant to the provisions of Section 10(a)(i) and (a)(ii)
above, in reduction of principal of the Reset Rate Notes; provided, that, in the
event on any Distribution Date the amount on deposit in the Accumulation Account
(excluding any Investment Earnings) would equal the Outstanding Amount of the
Reset Rate Notes, no additional amounts will be deposited into the Accumulation
Account and all amounts therein, less any Investment Earnings, will be
distributed by the Indenture Trustee, at the direction of the Administrator, as
set forth in Section 2.8 of the Administration Agreement, on the next Reset Date
to the Reset Rate Noteholders or the related Cross-Currency Swap Counterparty or
Counterparties (as applicable), and on such Reset Date the Reset Rate Notes will
no longer be Outstanding. Amounts on deposit in an Accumulation Account
(exclusive of Investment Earnings) may be used only to pay principal on the
Reset Rate Notes (or to the related Cross-Currency Swap Counterparty or
Counterparties) and for no other purpose. On each Distribution

                                 Appendix A-2-12

<PAGE>

Date, all Investment Earnings on deposit in the Accumulation Account will be
withdrawn by the Indenture Trustee, at the direction of the Administrator and
deposited into the Collection Account.

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

                  Section 12. Remarketing Agents; Swap Agent; Remarketing Fee
Account. (a) The initial Remarketing Agents, appointed pursuant to the terms of
the Remarketing Agreement, are Citigroup Global Markets Inc., Credit Suisse
First Boston LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated. The
terms and conditions of the Remarketing Agreement will govern the duties and
obligations of the Remarketing Agents and each Swap Agent. The Administrator,
the Trust and the Remarketing Agents will enter into on each (A) Remarketing
Terms Determination Date, a Remarketing Agency Agreement, in form and substance
substantially the same as Appendix B to the Remarketing Agreement, unless (i) a
Failed Remarketing is declared, or (ii) the holder of the Call Option has
delivered the Call Option Notice on or prior to such date; and (B) Spread
Determination Date, a Supplemental Remarketing Agency Agreement, in form and
substance substantially the same as Appendix C to the Remarketing Agreement,
unless (i) a Failed Remarketing is declared, (ii) the holder of the Call Option
has delivered the Call Option Notice on or prior to such date, or (iii) if
applicable, 100% of the Reset Rate Noteholders have timely delivered a Hold
Notice and the All Hold Rate will apply for the next Reset Period.

                  (b) If the Reset Rate Notes are in Foreign Exchange Mode or
will be reset into Foreign Exchange Mode, then pursuant to Section 13 of the
Remarketing Agreement, the Remarketing Agents shall appoint one or more Swap
Agents to act as agent for the Remarketing Agent and for the benefit of the
Reset Rate Noteholders, and instruct each Swap Agent to enter into a Reset Date
Currency Swap Agreement. The initial Swap Agent, appointed by the Remarketing
Agents pursuant to the Remarketing Agreement, is Citibank, N.A. The initial Swap
Agents shall be entitled to receive their pro rata share of the Remarketing
Agents' Upfront Fee paid to the Remarketing Agents pursuant to Section 3(c) of
the Remarketing Agreement. The duties and obligations of the Swap Agent are set
forth in the Remarketing Agreement.

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

                                 Appendix A-2-13

<PAGE>

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

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

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

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

                  (h) In accordance with Section 2.3(i) of the Administration
Agreement, on the Closing Date, the Trust will establish the Remarketing Fee
Account as an asset of the Trust in the name of the Indenture Trustee for the
benefit of the Remarketing Agents and the Reset Rate Noteholders. The fees
associated with each successful remarketing will be payable directly to the
Remarketing Agents from amounts on deposit from time to time in the Remarketing
Fee Account. On each applicable Distribution Date, Available Funds will be
deposited into the Remarketing Fee Account, in the priority set forth in Section
2.8(c) of the Administration Agreement, in an amount up to the Quarterly Funding
Amount; provided, that if the amount on

                                 Appendix A-2-14

<PAGE>

deposit in the Remarketing Fee Account, after the payment of any remarketing
fees therefrom, exceeds the sum of the Reset Period Target Amount for all Reset
Rate Notes, such excess will be withdrawn on the related Distribution Date,
deposited into the Collection Account and included in Available Funds for that
Distribution Date. All Investments Earnings on deposit in the Remarketing Fee
Account will be withdrawn on the next Distribution Date, deposited into the
Collection Account and included in Available Funds for that Distribution Date.
In the event that the fees owed to any Remarketing Agent on a Reset Date exceeds
the amount then on deposit in the Remarketing Fee Account, such shortfall shall
be paid from Available Funds on future Distribution Dates in the priority set
forth in Section 2.8(n) of the Administration Agreement. The Trust shall also be
responsible for certain remarketing costs and expenses to the extent set forth
in Section 3 of the Remarketing Agreement, which shall be paid on each
Distribution Date, to the extent of Available Funds, at the priority set forth
in Section 2.8(o) of the Administration Agreement.

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

                            TRANSFER RESTRICTIONS FOR
                              THE RESET RATE NOTES

                  1. Except as otherwise specified herein or as the context may
otherwise require, capitalized terms used but not otherwise defined in this
Appendix A-3 (this "Appendix") are defined in Appendix A-1, which also contains
rules as to usage that shall be applicable herein.

                  2. The Indenture Trustee, as Note Registrar, shall provide for
the registration of the Reset Rate Notes and of Transfers and exchanges of the
Reset Rate Notes pursuant to Section 2.4 of the Indenture.

                  3. The Reset Rate Notes will be initially represented by
registered notes of such class in global form and shall be issued in the manner
set forth in Sections 2.1, 2.2 and 2.10 of the Indenture. The global notes may
be reissued and represented by Reset Rate Notes of such class in definitive form
pursuant to Section 2.12 of the Indenture.

                  4. Any Transfer made in violation of Section 2.1 of the
Indenture of Reset Rate Notes that represent a beneficial interest in a U.S.
Rule 144A Global Note Certificate (as defined in Section 2.1 of the Indenture)
such that the beneficial interest is then held in either of the related Non-U.S.
Global Note Certificates (as defined in Section 2.1 of the Indenture), or vice
versa (other than on a Reset Date where such class is being reset from being
denominated in U.S. Dollars to Foreign Exchange Mode, or vice versa), shall be
null and void and of no effect.

                  5. Each purchaser of the Reset Rate Notes that represent a
beneficial interest in a Global Note Certificate will be deemed to have
represented and agreed, and each purchaser of a Definitive Note will be required
to certify in writing, that:

                  (i) (A) the purchaser is a QIB and is acquiring such Reset
         Rate Notes for its own account or as a fiduciary or agent for others
         (which others also must be QIBs), for investment purposes and not for
         distribution in violation of the Act, and it is able to bear the
         economic risk of an investment in the Reset Rate Notes and has such
         knowledge and experience in financial and business matters as to be
         capable of evaluating the merits and risks of purchasing the Reset Rate
         Notes or (B) the purchaser is a non-U.S. Person (as defined in
         Regulation S) outside the United States of America, acquiring the Reset
         Rate Notes pursuant to an exemption from registration in accordance
         with Rule 903 or Rule 904 of Regulation S;

                  (ii) the purchaser understands that the Reset Rate Notes are
         being offered only in a transaction that does not require registration
         under the Act and, if such purchaser decides to resell or otherwise
         Transfer such Reset Rate Notes, then it agrees that it will resell or
         Transfer such Reset Rate Notes only (A) so long as such Reset Rate
         Notes are eligible for resale pursuant to Rule 144A, to a person whom
         the seller reasonably believes is a QIB acquiring the Reset Rate Notes
         for its own account or as a fiduciary or agent for others (which others
         must also be QIBs) to whom notice is given that the resale or other

                                 Appendix A-3-1

<PAGE>

         Transfer is being made in reliance on Rule 144A, (B) pursuant to an
         effective registration statement under the Act, (C) pursuant to an
         exemption from registration available under the Act other than Rule
         144A, or (D) to a purchaser who is a non-U.S. Person (as defined in
         Regulation S) outside the United States of America, acquiring the Reset
         Rate Notes pursuant to an exemption from registration under the Act in
         accordance with Rule 903 or Rule 904 of Regulation S, in each case in
         accordance with any applicable United States state securities or "blue
         sky" laws or any securities laws of any other jurisdiction;

                  (iii) unless the relevant legend set out below has been
         removed from the Reset Rate Notes such purchaser shall notify each
         transferee of the Reset Rate Notes that (A) such Reset Rate Notes have
         not been registered under the Act, (B) the holder of such Reset Rate
         Notes is subject to the restrictions on the resale or other Transfer
         thereof described in paragraph (ii) above, (C) such transferee shall be
         deemed to have represented (1) as to its status as a QIB or a purchaser
         acquiring the Reset Rate Notes in an offshore transaction pursuant to
         the requirements of Regulation S, as the case may be, (2) if such
         transferee is a QIB, that such transferee is acquiring the Reset Rate
         Notes for its own account or as a fiduciary or agent for others (which
         others also must be QIBs) (or that such transferee is acquiring such
         Reset Rate Notes in reliance on an exemption under the Act other than
         Rule 144A or pursuant to an effective registration statement under the
         Act), (3) if such transferee is a non-U.S. Person (as defined in
         Regulation S) outside the United States of America, that such

         from registration under the Act in accordance with the requirements of
         Rule 903 or Rule 904 of Regulation S, (4) that such transferee is not
         an underwriter within the meaning of Section 2(11) of the Act, and (5)
         that such transferee shall be deemed to have agreed to notify its
         subsequent transferees as to the foregoing;

                  (iv) the acquisition or purchase by an employee benefit plan
         or other retirement arrangements ("Plan") of a Reset Rate Note will not
         constitute or otherwise result in: (A) 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 (B) 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.

                  6. By acceptance of a Reset Rate Note, whether upon original
issuance or subsequent Transfer, each Reset Rate Noteholder or Note Owner, as
applicable, of such Reset Rate Note (or a beneficial interest therein) offered
and sold only to a QIB in reliance on Rule 144A, acknowledges or is deemed to
acknowledge, as the case may be, the restrictions on the Transfer of such Reset

                  THE HOLDER OF THIS NOTE AND ANY BENEFICIAL OWNER OF ANY
                  INTEREST THEREIN SHALL BE DEEMED, BY ITS ACCEPTANCE OR
                  PURCHASE HEREOF, TO HAVE AGREED TO ANY SUCH AMENDMENT OR
                  SUPPLEMENT (EACH OF WHICH SHALL BE CONCLUSIVE AND BINDING ON
                  THE HOLDER HEREOF AND ALL FUTURE HOLDERS OF THIS NOTE AND ANY
                  CLASS A-5 NOTES ISSUED IN EXCHANGE OR SUBSTITUTION HEREFOR,
                  WHETHER OR NOT ANY NOTATION THEREOF IS MADE HEREON) AND AGREES
                  TO TRANSFER THIS NOTE ONLY IN ACCORDANCE WITH ANY SUCH
                  AMENDMENT OR SUPPLEMENT IN ACCORDANCE WITH APPLICABLE LAW IN
                  EFFECT AT THE DATE OF SUCH TRANSFER.

                  Upon the Transfer, exchange or replacement of a Rule 144A
Class A-5 Certificate bearing the applicable legends set forth above, or upon
specific request for removal of the legends, the Trust or the Registrar will
deliver only replacement Rule 144A Class A-5 Certificates, that bear such Class
A-5 Securities Legend, or will refuse to remove such Class A-5 Securities
Legend, unless there is delivered to the Trust and the Registrar such
satisfactory evidence (which may include a legal opinion) as may reasonably be
required by the Trust and the Indenture Trustee that neither the applicable
legends nor the restrictions on Transfer set forth therein are required to
ensure compliance with the provisions of the Act.

                  Whenever a global note certificate is to be exchanged for a
Definitive Note, such Definitive Note will be issued within five business days
of delivery to the Registrar of the information and any required certification
described in the preceding paragraph against the surrender of the relevant
global note certificate at the specified office of the Registrar. Such exchange
shall be effected in accordance with the regulations concerning the Transfer and
registration from time to time relating to the Class A-5 Notes and shall be
effected without charge, but against such indemnity as the Registrar may require
in respect of any tax or other duty of whatsoever nature which may be levied or
imposed in connection with such exchange.

                  Each Class A-5 Noteholder or Note Owner, as applicable, of
such Class A-5 Note, by its acceptance of a Class A-5 Note or a beneficial
interest therein, respectively, also agrees that it will Transfer such Class A-5
Note or beneficial interest therein, as the case may be, only as provided herein
and in accordance with the Indenture. In addition, by acceptance of any Class
A-5 Note or beneficial interest therein, as applicable, each proposed transferee
thereof is hereby deemed to have agreed with the conditions set forth in the
Class A-5 Securities Legend and agreed, by virtue of its acceptance of such
Class A-5 Note or beneficial interest therein, as the case may be, to indemnify
the Administrator, the Depositor, the Servicer, the Indenture Trustee, the
Eligible Lender Trustee and the Issuer against any and all liability that may
result if such Transfer is not made in a manner consistent with the restrictions
set forth in the Class A-5 Securities Legend. In addition to any applicable
restrictions in the Indenture, with respect to the Transfer and registration of
Transfer of any Definitive Note representing an interest in the Class A-5 Notes
registered in the name of a Class A-5 Noteholder other than DTC or its nominee,
to a transferee that takes delivery in the form of a Definitive Note, the
Indenture Trustee shall register the Transfer of such Definitive Note if (i) (A)
the requested Transfer is

                                 Appendix A-4-4

<PAGE>

being made to a transferee who has provided the Indenture Trustee and the
Administrator with a transferee Certificate, substantially in the form attached
as Annex A hereto, (B) such transferee has provided comparable evidence as to
its QIB status, or (C) such Transfer is being made in reliance on an exemption
from registration under the Act other than Rule 144A and such transferor has
provided the Indenture Trustee and the Administrator with reasonably acceptable
evidence thereof and (ii) the applicable transferor has provided the Indenture
Trustee and the Administrator with a Transferor Letter, substantially in the
form of Annex B hereto.

                  1. The Class A-5 Notes will be issued initially only in
minimum denominations of $250,000, and additional increments of $1,000, in
excess thereof. The Class A-5 Notes are exchangeable at any time into an equal
aggregate principal amount of Class A-5 Notes of the same class of different
authorized denominations pursuant to Section 2.4 of the Indenture.

                  2. Class A-5 Notes may be presented or surrendered pursuant to
Section 2.4 of the Indenture.

                  3. No service charge shall be made to a Noteholder for any
registration of Transfer or exchange of Class A-5 Notes, but the Indenture
Trustee may require payment of a sum sufficient to cover any tax or other
governmental charge pursuant to Section 2.4 of the Indenture.

                  4. The Indenture Trustee shall cancel all Class A-5 Notes
surrendered for Transfer or exchange pursuant to Section 2.8 of the Indenture.

                  5. For so long as the Class A-5 Notes are "restricted
securities" within the meaning of Rule 144(a)(3) of the Securities Act, (1) the
Administrator will provide or cause to be provided to any holder of such Class
A-5 Notes and any prospective purchaser thereof designated by such a holder,
upon the request of such holder or prospective purchaser, the information
required to be provided to such holder or prospective purchaser by Rule
144A(d)(4) under the Act; and (2) the Administrator shall update such
information from time to time in order to prevent such information from becoming
false and misleading and will take such other actions as are necessary to ensure
that the safe harbor exemption from the registration requirements of the Act
under Rule 144A is and will be available for resales of such Class A-5 Notes
conducted in accordance with Rule 144A.

undersigned is accepting ownership of the Class A-5 Notes in compliance with the
