                                    THE NOTES

     Section 2.01.  Form. The Notes, together with the Indenture Trustee's
certificate of authentication, shall be in substantially the forms set forth in
Exhibit A, with such appropriate insertions, omissions, substitutions and other
variations as are required or permitted by this Indenture and may have such
letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may, consistently herewith, be determined by the
officers executing the Notes, as evidenced by their execution of the Notes. Any
portion of the text of any Note may be set forth on the reverse thereof, with an
appropriate reference thereto on the face of the Note.

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

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

     Section 2.02.  Execution, Authentication and Delivery. The Notes shall be
executed on behalf of the Issuer by any of its Authorized Officers. The
signature of any such Authorized Officer on the Notes may be manual or
facsimile.

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

     The Indenture Trustee shall upon Issuer Order authenticate and deliver
Notes for original issue in an aggregate principal amount of $1,507,574,000, of
which $635,000,000 shall be denominated Class A-1 Notes, $378,000,000 shall be
denominated Class A-2 Notes, $277,150,000 shall be denominated Class A-3 Notes,
$100,000,000 shall be denominated Class A-4 Notes, $49,242,000 shall be
denominated Class B Notes and $68,182,000 shall be denominated Class C Notes.

     Each Note shall be dated the date of its authentication. The Notes shall be
issuable as registered Notes in multiple denominations of $1,000.

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

     Section 2.03.  Temporary Notes. Pending the preparation of Definitive
Notes, the Issuer may execute, and upon receipt of an Issuer Order the Indenture
Trustee shall authenticate and deliver, temporary Notes which are printed,
lithographed, typewritten, mimeographed or

                                        3

<PAGE>

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 3.02, 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 2.04.  Registration; Registration of Transfer and Exchange. The
Issuer shall cause to be kept a register (the "Note Register") in which, subject
to such reasonable regulations as it may prescribe, the Issuer shall provide for
the registration of Notes and the registration of transfers of Notes. The
Indenture Trustee shall be "Note Registrar" for the purpose of registering Notes
and transfers of Notes as herein provided. Upon any resignation of any Note
Registrar, the Issuer shall promptly appoint a successor or, if it elects not to
make such an appointment, assume the duties of Note Registrar.

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

     Upon surrender for registration of transfer of any Note at the office or
agency of the Issuer to be maintained as provided in Section 3.02, if the
requirements of Section 8-401(1) of the UCC are met, the Issuer shall execute,
and the Indenture Trustee shall authenticate and the Noteholder shall obtain
from the Indenture Trustee, in the name of the designated transferee or
transferees, one or more new Notes in any authorized denominations and a like
aggregate principal amount.

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

                                        4

<PAGE>

     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 2.03 or 9.06 not involving any
transfer.

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

     Section 2.05.  Mutilated, Destroyed, Lost or Stolen Notes. If (i) any
mutilated Note is surrendered to the Indenture Trustee, or the Indenture Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any
Note, and (ii) there is delivered to the 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.

                                        5

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

     Section 2.07.  Payment of Principal and Interest; Note Interest Shortfall.
(a) The Notes shall accrue interest as provided in the forms of Notes set forth
in Exhibit and such interest shall be payable on each applicable Distribution
Date as specified therein, subject to Section 3.01. 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 Clearing Agency (initially, such nominee to be Cede & Co.),
payment shall be made by wire transfer in immediately available funds to the
account designated by such nominee and except for the final installment of
principal payable with respect to such Note on a Distribution Date or on the
Note Final Maturity Date for such Note which shall be payable as provided below.
The funds represented by any such checks returned undelivered shall be held in
accordance with Section 3.03.

     (b)  The principal of each Note shall be payable in installments on
each Distribution Date as provided in the forms of such note set forth in
Exhibit A. Notwithstanding the foregoing, the entire unpaid principal amount of
each class of the Notes shall be due and payable, if not previously paid, on the
Note Final Maturity Date for such class of Notes and on the date on which an
Event of Default shall have occurred and be continuing if the Indenture Trustee
or the Noteholders of the Notes representing not less than a majority of the
Outstanding Amount of the Controlling Notes have declared the Notes to be
immediately due and payable in the manner provided in Section 5.02. All
principal payments on the Notes shall be made pro rata to the

                                        6

<PAGE>

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 10.02.

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

     Section 2.08.  Cancellation. All Notes surrendered for payment,
registration of transfer, exchange or redemption shall, if surrendered to any
Person other than the Indenture Trustee, be delivered to the Indenture Trustee
and shall be promptly cancelled by the Indenture Trustee. The Issuer may at any
time deliver to the Indenture Trustee for cancellation any Notes previously
authenticated and delivered hereunder which the Issuer may have acquired in any
manner whatsoever and all Notes so delivered shall be promptly cancelled by the
Indenture Trustee. No Notes shall be authenticated in lieu of or in exchange for
any Notes cancelled as provided in this Section, except as expressly permitted
by this Indenture. All 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 2.09.  Release of Collateral. Subject to Section 11.01 and the
terms of the Basic Documents, the Indenture Trustee shall release property from
the lien of this Indenture only upon receipt of an Issuer Request accompanied by
an Officers' Certificate of the Issuer, an Opinion of Counsel and Independent
Certificates in accordance with TIA Sections 314(c) and 314(d)(1) or an Opinion
of Counsel in lieu of such Independent Certificates to the effect that the TIA
does not require any such Independent Certificates.

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

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

          (ii)  the Note Registrar and the Indenture Trustee, and their
     respective directors, officers, employees and agents, may deal with the
     Clearing Agency for all

                                        7

<PAGE>

     purposes (including the payment of principal of and interest and other
     amounts on the Notes) as the authorized representative of the Note Owners;

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

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

          (v)   whenever this Indenture requires or permits actions to be
     taken based upon instructions or directions of Noteholders of Notes
     evidencing a specified percentage of the Outstanding Amount of the Notes,
     the Clearing Agency shall be deemed to represent such percentage only to
     the extent that it has received instructions to such effect from Note
     Owners and/or Clearing Agency Participants owning or representing,
     respectively, such required percentage of the beneficial interest in the
     Notes and has delivered such instructions to the Indenture Trustee; 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 to the Noteholders is required under this Indenture, unless and
until Definitive Notes shall have been issued to Note Owners pursuant to Section
2.12, the Indenture Trustee shall give all such notices and communication
specified herein to be given to Noteholders to the Clearing Agency.

     Section 2.12.  Definitive Notes. If (i) the Administrator advises the
Indenture Trustee in writing that the Clearing Agency is no longer willing or
able to discharge its responsibilities with respect to the Notes, and the
Administrator is unable to locate a successor, (ii) the Administrator at its
option advises the Indenture Trustee in writing that it elects to terminate the
book-entry system through the Clearing Agency or (iii) after the occurrence of
an Event of Default, a Servicer Default or an Administrator Default, Note Owners
representing beneficial interests aggregating at least a majority of the
Outstanding Amount of the Notes advise the Clearing Agency (which shall then
notify the Indenture Trustee) in writing that the continuation of a book-entry
system through the Clearing Agency is no longer in the best interests of the
Note

                                        8

<PAGE>

Owners, then the Indenture Trustee shall cause the Clearing Agency to notify all
Note Owners, through the Clearing Agency, of the occurrence of any such event
and of the availability of Definitive Notes to Note Owners requesting the same.
Upon surrender to the Indenture Trustee of the typewritten Notes representing
the Book-Entry Notes by the Clearing Agency, accompanied by registration
instructions, the Issuer shall execute and the Indenture Trustee shall
authenticate the Definitive Notes in accordance with the instructions of the
Clearing Agency. None of the Issuer, the Note Registrar or the Indenture Trustee
shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such instructions.
Upon the issuance of Definitive Notes, the Indenture Trustee shall recognize the
holders of the Definitive Notes as Noteholders.

     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.

                                   ARTICLE III

                                    COVENANTS

     Section 3.01.  Payment to Noteholders. The Issuer shall duly and punctually
pay the principal and interest, if any, with respect to the Notes in accordance
with the terms of the Notes and this Indenture. Without limiting the foregoing,
the Issuer shall cause to be distributed to Noteholders, in accordance with the
Administration Agreement, that portion of the amounts on deposit in the Trust
Accounts on a Distribution Date (other than any Eligible Investments deposited
therein that will mature on the Business Day preceding a subsequent Distribution
Date) which the Noteholders are entitled to receive pursuant to the
Administration Agreement. Amounts properly withheld under the Code by any Person
from a payment to any Noteholder of interest and/or principal shall be
considered as having been paid by the Issuer to such Noteholder for all purposes
of this Indenture.

     Section 3.02.  Maintenance of Office or Agency. The Issuer shall maintain
in the Borough of Manhattan, The City of New York, an office or agency where
Notes may be surrendered for registration of transfer or exchange, and where
notices and demands to or upon the Issuer in respect of the Notes and this
Indenture may be served. The Issuer hereby initially appoints the Indenture
Trustee to serve as its agent for the foregoing purposes. The Issuer shall give
prompt written notice to the Indenture Trustee of the location, and of any
change in the location, of any such office or agency. If at any time the Issuer
shall fail to maintain any such office or agency or shall fail to furnish the
Indenture Trustee with the address thereof, such surrenders, notices and demands
may be made or served at the Corporate Trust Office, and the Issuer hereby
appoints the Indenture Trustee as its agent to receive all such surrenders,
notices and demands.

                                        9

<PAGE>

     Section 3.03.  Money for Payments To Be Held in Trust. As provided in
Sections 8.02(a) and (b), all payments of amounts due and payable with respect
to any Notes that are to be made from amounts distributed from the Collection
Account or any other Trust Account pursuant to Sections 2.07 and 2.08 of the
Administration Agreement shall be made on behalf of the Issuer by the Indenture
Trustee or by another Paying Agent, and no amounts so distributed from the
Collection Account for payments of Notes shall be paid over to the Issuer except
as provided in this Section.

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

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

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

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

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

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

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

     The Issuer may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, by Issuer Order direct
any Paying Agent to pay to the Indenture Trustee all sums held in trust by such
Paying

                                       10

<PAGE>

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, 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 3.04.  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 3.05.  Protection of Indenture Trust Estate. The Issuer will from
time to time execute and deliver all such supplements and amendments hereto and
all such financing statements, continuation statements, 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

                                       11

<PAGE>

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

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

     Section 3.06.  Opinions as to Indenture Trust Estate. (a) On the Closing
Date, the Issuer shall furnish to the Indenture Trustee an Opinion of Counsel
either stating that, in the opinion of such counsel, such action has been taken
with respect to the recording and filing of this Indenture 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
2004, 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 3.07.  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

                                       12

<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 5.01 of
the Servicing Agreement, or to the Administrator of the Administrator's rights
and powers, pursuant to Section 5.01 of the Administration Agreement, the Issuer
shall appoint a successor servicer (the "Successor Servicer") or a successor
administrator (the "Successor Administrator"), respectively, and such Successor
Servicer or Successor Administrator, as the case may be, shall accept its
appointment by a written assumption in a form acceptable to the Indenture
Trustee. In the event that a Successor Servicer or Successor Administrator has
not been appointed and accepted its appointment at the time when the Servicer or
Administrator, as the case may be, ceases to act as Servicer or Administrator,
respectively, the Indenture Trustee without further action shall automatically
be appointed the Successor Servicer or Successor Administrator, as the case may
be. The Indenture Trustee may resign as the Servicer or the Administrator by
giving written notice of resignation to the Issuer and in such event will be
released from such duties and obligations, such release not to be effective
until the date a new servicer or a new administrator enters into an agreement
with the Issuer as provided below. 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 whose regular business includes the servicing or
administration of student loans and (ii) enter into a servicing agreement or an
administration agreement, respectively, with the Issuer having substantially the
same provisions as the provisions of the Servicing Agreement and the
Administration Agreement, as applicable. If within 30 days after the delivery of
the notice referred to above, the Issuer shall not have obtained such a new
servicer or new administrator, as the case may be, the Indenture Trustee may
appoint, or may petition a court of competent jurisdiction to appoint, a
Successor Servicer or Successor Administrator; provided, however, that such
right to appoint or to petition for the appointment of any such successor shall
in no event relieve the Indenture Trustee from any obligations otherwise imposed
on it under the Basic Documents until such successor has in fact assumed such
appointment. In connection with any such appointment, the Indenture Trustee

                                       13

<PAGE>

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 5.02 of the Servicing Agreement and Section 5.02 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

Independent Certificate from a firm of certified public accountants, each
meeting the applicable requirements of Section 11.01(a) and, subject to Section
11.02, each stating that all conditions precedent herein provided for relating
to the satisfaction and discharge of this Indenture have been complied with.

     Section 4.02.  Application of Trust Money. All moneys deposited with the
Indenture Trustee pursuant to Section 4.01 hereof shall be held in trust and
applied by it, in accordance with the provisions of the Notes and this
Indenture, to the payment, either directly or through any Paying Agent, as the
Indenture Trustee may determine, to the Noteholders of the particular Notes for
the payment or redemption of which such moneys have been deposited with the
Indenture Trustee, of all sums due and to become due thereon for principal and
interest; but such moneys need not be segregated from other funds except to the
extent required herein or in the Administration Agreement or required by law.

     Section 4.03.  Repayment of Moneys Held by Paying Agent. In connection with
the satisfaction and discharge of this Indenture with respect to the Notes, all
moneys then held by any Paying Agent other than the Indenture Trustee under the
provisions of this Indenture with respect to such Notes shall, upon demand of
the Issuer, be paid to the Indenture Trustee to be held and applied according to
Section 3.03 and thereupon such Paying Agent shall be released from all further
liability with respect to such moneys.

     Section 4.04.  Auction of Trust Student Loans. Any Trust Student Loans
remaining in the Trust as of the end of the Collection Period immediately
preceding the earliest Distribution Date on which the Pool Balance is equal to
10% or less of the initial Pool Balance three business days prior to such
Distribution Date (the "Trust Auction Date") shall be offered for sale by the
Indenture Trustee unless the Servicer has exercised its option to purchase the
Trust Estate as described in Section 6.01(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 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 4.04. 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 SLM Education
Credit Finance Corporation and the Depositor, to offer bids only if the Pool
Balance as of the applicable Trust Auction Date is equal to 10% or less of the
Initial Pool Balance and such bid does not exceed the fair market value of the
Trust Student Loans as of the Trust Auction Date. If at least two bids are
received, the Indenture Trustee shall solicit and resolicit new bids from all
participating bidders until only one bid remains or the remaining bidders
decline to resubmit bids. The Indenture Trustee shall accept the highest of such
remaining bids if it is equal to or in excess of both the Minimum Purchase
Amount and the fair market value of such Trust Student Loans as of the end of
the Collection Period immediately preceding the Trust Auction Date. If at least
two bids are not received or the highest bid after the resolicitation process is
completed is not equal to or in excess of the higher of the Minimum Purchase
Amount and the fair market value of the Trust Student Loans, the Indenture
Trustee shall not consummate such sale. The Indenture Trustee may consult, and,
at the direction of the Depositor, shall consult, with a financial advisor,
including an underwriter of the Notes or the Administrator, to determine if the

                                       20

<PAGE>

fair market value of the Trust Student Loans has been offered. The proceeds of
any such sale will be applied in the order of priority set forth in Section
5.04(b). If the sale is not consummated in accordance with the foregoing, the
Indenture Trustee may, but shall not be under any obligation to, solicit bids
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 6.01(a) of
the Administration Agreement with respect to each such future Distribution Date.

     (a)  default in the payment of any interest on any Controlling Note when
the same becomes due and payable, and such default shall continue for a period
of five Business Days or more;

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

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

jurisdiction in the premises in respect of the Issuer or any substantial part of
the Indenture Trust Estate in an involuntary case under any applicable Federal

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

consecutive days; or

<PAGE>

     (e)  the commencement by the Issuer of a voluntary case under any
applicable Federal or state bankruptcy, insolvency or other similar law now or
hereafter in effect, or the consent by the Issuer to the entry of an order for
relief in an involuntary case under any such law, or the consent by the Issuer
to the appointment or taking possession by a receiver, liquidator, assignee,
custodian, trustee, sequestrator or similar official of the Issuer or for any
substantial part of the Indenture Trust Estate, or the making by the Issuer of
any general assignment for the benefit of creditors, or the failure by the
Issuer generally to pay its debts as such debts become due, or the taking of
action by the Issuer in furtherance of any of the foregoing.

     Section 5.02.  Acceleration of Maturity; Rescission and Annulment. If an
Event of Default should occur and be continuing, then and in every such case the
Indenture Trustee or the Noteholders of Notes representing not less than a
majority of the Outstanding Amount of the Controlling 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 5.04 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
Controlling Notes, by written notice to the Issuer and the Indenture Trustee,
may rescind and annul such declaration and its consequences if:

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

          (i)  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

          (ii) 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

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

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

     Section 5.03.  Collection of Indebtedness and Suits for Enforcement by
Indenture Trustee. The Issuer covenants that if (i) default is made in the
payment of any interest on any Controlling 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

                                       22

<PAGE>

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 2.07 and in addition thereto such further amount as shall
be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Indenture
Trustee and its agents and counsel.

     (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 5.04, in its discretion, proceed
to protect and enforce its rights and the rights of the Noteholders, by such
appropriate Proceedings as the Indenture Trustee shall deem most effective to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy or legal or equitable
right vested in the Indenture Trustee by this Indenture or by law.

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

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

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

                                       23

<PAGE>

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

          (iv)  to file such proofs of claim and other papers or documents as
     may be necessary or advisable in order to have the claims of the Indenture
     Trustee or the Noteholders allowed in any judicial proceedings relative to
     the Issuer, its creditors and its property;

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

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

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

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

     Section 5.04.  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 5.05):

     (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;

                                       24

<PAGE>

          (iii)  exercise any remedies of a secured party under the UCC with
     respect to the Trust Estate and take any other appropriate action to
     protect and enforce the rights and remedies of the Indenture Trustee 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 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 5.01(a) or (b), unless (A) the
Noteholders of 100% of the Outstanding Amount of the Controlling Notes consent
thereto, (B) the proceeds of such sale or liquidation distributable to the
Noteholders of the Controlling Notes are sufficient to discharge in full all
amounts then due and unpaid upon such Notes for principal and interest or (C)
the Indenture Trustee determines that the Indenture Trust Estate will not
continue to provide sufficient funds for the payment of principal of and
interest on the Controlling Notes as they would have become due if the
Controlling 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 5.01(a) or (b) with respect
to the Class A Notes, unless (D) the proceeds of such sale or liquidation
distributable to the Class B Noteholders plus the proceeds of the sale or
liquidation of the Trust Estate distributable to the Class C Noteholders are
sufficient to pay to the Class B Noteholders and the Class C Noteholders the
outstanding principal plus accrued and unpaid interest thereon or (E) if 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 C Noteholders would not be sufficient to pay to the Class B
Noteholders and the Class C Noteholders the outstanding principal plus accrued
and unpaid interest thereon, the Class B Noteholders and the Class C Noteholders
of at least a majority of the principal amount of the Class B Notes and the
Class C 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 8.02, following the
occurrence and during the continuation of an Event of Default specified in
Section 5.01(a), 5.01(b), 5.01(d) or 5.01(e) which has resulted in an
acceleration of the Notes (or following the occurrence of any such event after
an Event of Default specified in Section 5.01(c) has occurred and the Trust has
been liquidated), if the Indenture Trustee collects any money or property, it
shall pay out the money or property (and other amounts including amounts held on
deposit in the Reserve Account and the Cash Capitalization Account) held as
Collateral for the benefit of the

                                       25

<PAGE>

Noteholders, net of liquidation costs associated with the sale of the assets of
the Trust, in the following order:

          (i)    to the Indenture Trustee for amounts due under Section 6.07;

          (ii)   to the Servicer for any due and unpaid Primary Servicing Fees;

          (iii)  to the Administrator, any due and unpaid Administration Fees;

          (iv)   to the Swap Counterparty, any Swap Payment payable to the Swap
     Counterparty under the Swap Agreement for such Distribution Date;

          (v)    pro rata, based on the Class Note Balance and the amount of any
     Swap Termination Payments due and payable by the Issuer to the Swap
     Counterparty under this clause (v);

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

                      (B)  to the Swap Counterparty, the amount of any Swap
                 Termination Payments, if any, due to the Swap Counterparty
                 under the Swap Agreement due to a Termination Event resulting
                 from a payment default by the Issuer or the insolvency of the
                 Issuer; provided, that if any amounts allocable to the Class A
                 Notes are not needed to pay Class A Noteholders' Interest
                 Distribution Amount as of such Distribution Date, such amounts
                 will be applied to pay the portion, if any, of any Swap
                 Termination Payments remaining unpaid;

          (vi)   A: so long as the Swap Agreement is in effect, to the Class A
     Noteholders, ratably, an amount sufficient to reduce their respective Class
     A Note Balance to zero; and

                 B: if the Swap Agreement is not in effect, pro rata (1) to the
     Class A Noteholders, ratably, an amount sufficient to reduce the respective
     principal balances of the Class A Notes to zero and (2) to the Swap
     Counterparty under the Swap Agreement, the amount (to the extent not paid
     under clause (v) above) of any Swap Termination Payment due to the Swap
     Counterparty due to a Termination Event resulting from a "Cross Default"
     under 5(a)(vi) of the Swap Agreement by the Issuer. For the avoidance of
     doubt, any Swap Termination Payment due to the Swap Counterparty resulting
     from such a "Cross-Default" that is a result of the bankruptcy or
     insolvency of the Trust shall be payable under clause (v) above.

          (vii)  to the Class B Noteholders for amounts due and unpaid on the
     Class B Notes for interest, ratably, without preference or priority of any
     kind, according to the amounts due and payable on the Class B Notes for
     such interest;

                                       26

<PAGE>

          (viii) to Class B Noteholders, an amount sufficient to reduce the
     Class B Note Balance to zero;

          (ix)   to the Class C Noteholders, for amounts due and unpaid on the
     Class C Notes for interest, ratably, without preference or priority of any
     kind, according to the amounts due and payable on the Class C Notes for
     such interest;

          (x)    to the Class C Noteholders, an amount sufficient to reduce the
     Class C Note Balance to zero;

          (xi)   to the Servicer, for any unpaid Carryover Servicing Fees;

          (xii)  to the Swap Counterparty, the amount of any Swap Termination
     Payment due and payable by the Issuer to the Swap Counterparty under the
     Swap Agreement and not payable in clause (v) or (vi) above and the amount
     of any termination payment due and payable by the Issuer to the Cap
     Counterparty under the Interest Rate Cap Agreement; and

          (xiii) to the Certificateholders, any remaining funds.

     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 5.05.  Optional Preservation of the Trust Student Loans. If the
Notes have been declared to be due and payable under Section 5.02 following an
Event of Default and such declaration and its consequences have not been
rescinded and annulled, the Indenture Trustee may, but need not, elect to
maintain possession of the Indenture Trust Estate. It is the desire of the
parties hereto and the 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 5.06.  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:

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

     (b)  the Noteholders of not less than 25% of the Outstanding Amount of the
Controlling 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;

                                       27

<PAGE>

     (c)  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;

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

     (e)  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 Controlling 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 5.07.  Unconditional Rights of Noteholders To Receive Principal and
Interest. Notwithstanding any other provisions in this Indenture, any Noteholder
shall have the right, which is absolute and unconditional, to receive payment of
the principal of and interest on such Note on or after the respective due dates
thereof expressed in such Note or in this Indenture (or, in the case of
redemption, on or after the Redemption Date) and to institute suit for the
enforcement of any such payment, and such right shall not be impaired without
the consent of such Noteholder.

     Section 5.08.  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 5.09.  Rights and Remedies Cumulative. No right or remedy herein
conferred upon or reserved to the Indenture Trustee or to the Noteholders is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

                                       28

<PAGE>

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

     Section 5.11.  Control by Noteholders. The Noteholders of a majority of the
Outstanding Amount of the Controlling 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

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

     (b)  subject to the express terms of Section 5.04, any direction to the
Indenture Trustee to sell or liquidate the Indenture Trust Estate shall be by
the Noteholders of not less than 100% of the Outstanding Amount of the
Controlling Notes;

     (c)  if the conditions set forth in Section 5.05 have been satisfied and
the Indenture Trustee elects to retain the Indenture Trust Estate pursuant to
such Section, then any direction to the Indenture Trustee by Noteholders of less
than 100% of the Outstanding Amount of the Controlling Notes to sell or
liquidate the Indenture Trust Estate shall be of no force and effect; and

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

provided, however, that subject to Section 6.01, the Indenture Trustee need not
take any action that it determines might involve it in liability or might
materially adversely affect the rights of 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 5.02,
the Noteholders of not less than a majority of the Outstanding Amount of the
Controlling 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

                                       29

<PAGE>

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

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

     Section 5.15.  Action on Notes. The Indenture Trustee's right to seek and
recover judgment on the Notes or under this Indenture shall not be affected by
the seeking, obtaining or application of any other relief under or with respect
to this Indenture. Neither the lien of this Indenture nor any rights or remedies
of the Indenture Trustee or the Noteholders shall be impaired by the recovery of
any judgment by the Indenture Trustee against the Issuer or by the levy of any
execution under such judgment upon any portion of the Indenture Trust Estate or
upon any of the assets of the Issuer. Any money or property collected by the
Indenture Trustee shall be applied in accordance with Section 5.04(b).

     Section 5.16.  Performance and Enforcement of Certain Obligations.

     (a)  Promptly following a request from the Indenture Trustee to do so and
at the Administrator's expense, the Issuer shall take all such lawful action as
the Indenture Trustee may request to compel or secure the performance and
observance by the Depositor, SLM Education Credit Finance Corporation, 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 a
Basic Document, 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 a Basic Document, 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, SLM Education
Credit Finance Corporation, the Administrator or the Servicer thereunder and the
institution of legal or administrative actions or proceedings to compel or
secure performance by the Depositor, SLM Education Credit Finance Corporation,
the Administrator or the Servicer of each of their obligations under a Basic
Document, respectively.

                                       30

<PAGE>

     (b)  If an Event of Default has occurred and is continuing, the Indenture
Trustee may, and at the written direction of the Noteholders of 66-2/3% of the
Controlling Outstanding Amount of the Notes shall, exercise all rights,
remedies, powers, privileges and claims of the Issuer against the Depositor, SLM
Education Credit Finance Corporation, the Administrator or the Servicer under or
in connection with a Basic Document, respectively, including the right or power
to take any action to compel or secure performance or observance by the
Depositor, SLM Education Credit Finance Corporation, 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 a Basic Document, respectively, and any right of the
Issuer to take such action shall be suspended.

                                   ARTICLE VI

                              THE INDENTURE TRUSTEE

     Section 6.01.  Duties of Indenture Trustee.

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

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

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

          (ii)  in the absence of bad faith on its part, the Indenture Trustee
     may conclusively rely, as to the truth of the statements and the
     correctness of the opinions 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 clause (c) does not limit the effect of clause (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

                                       31

<PAGE>

          (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 of the Noteholders received by it pursuant to this Indenture.

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

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

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

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

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

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

     (j)  The rights and protections of the Indenture Trustee under Sections
6.01 and 6.02 shall apply to each of the Basic Documents as though explicitly
incorporated therein.

     Section 6.02.  Rights of Indenture Trustee. (a) The Indenture Trustee may
rely on any document believed by it to be genuine and to have been signed or
presented by the proper Person. The Indenture Trustee need not investigate any
fact or matter stated in such document.

     (b)  Before the Indenture Trustee acts or refrains from acting, it may
require and shall be entitled to receive an Officers' Certificate of the Issuer
and/or an Opinion of Counsel. The Indenture Trustee may conclusively rely on any
such Opinion of Counsel or Officers' Certificate and 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.

                                       32

<PAGE>

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

     Section 6.04.  Indenture Trustee's Disclaimer. The Indenture Trustee shall
not be responsible for and makes no representation as to the validity or
adequacy of this Indenture or the Notes, it shall not be accountable for the
Issuer's use of the proceeds from the Notes, and it shall not be responsible for
any statement of the Issuer in the Indenture or in any document issued in
connection with the sale of the Notes or in the Notes other than the Indenture
Trustee's certificate of authentication.

     Section 6.05.  Notice of Defaults. If a Default or a Servicer Default
occurs and is continuing and if it is either actually known to a Responsible
Officer or written notice of the existence thereof has been delivered to a
Responsible Officer of the Indenture Trustee, the Indenture Trustee shall mail
notice of the Default to each Noteholder within 90 days and to each Rating
Agency as soon as practicable within 30 days after it occurs. Except in the case
of a Default in payment of principal of or interest on any Note (including
payments pursuant to the mandatory redemption provisions of such Note), the
Indenture Trustee may withhold the notice if and so long as a committee of its
Responsible Officers in good faith determines that withholding the notice is in
the interests of Noteholders. Except as provided in the first sentence of this
Section 6.05, in no event shall the Indenture Trustee be deemed to have
knowledge of a Default, a Servicer Default or an Event of Default.

     Section 6.06.  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.

                                       33

     Section 6.07.  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 including the reasonable
expenses and disbursements of its counsel incurred or made by it as provided in
such separate agreement. The Indenture Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Issuer
shall cause the Administrator to indemnify the Indenture Trustee and its
directors, officers, employees and agents against any and all loss, liability or
expense (including attorneys' fees) incurred by it in connection with the
administration of this trust and the performance of its duties hereunder and
under the other Basic Documents. The Indenture Trustee shall notify the Issuer
and the Administrator promptly of any claim for which it may seek indemnity.
Failure by the Indenture Trustee to so notify the Issuer and the Administrator
shall not relieve the Issuer or the Administrator of its obligations hereunder
and under the other Basic Documents. The Issuer shall cause the Administrator to
defend the claim and the Administrator shall not be liable for the legal fees
and expenses of the Indenture Trustee after it has assumed such defense;
provided, however, that, in the event that there may be a conflict between the
positions of the Indenture Trustee and the Administrator in conducting the
defense of such claim, the Indenture Trustee shall be entitled to separate
counsel acceptable to it in its sole discretion the reasonable fees and expenses
of which shall be paid by the Administrator on behalf of the Issuer. Neither the
Issuer nor the Administrator need reimburse any expense or indemnify against any
loss, liability or expense incurred by the Indenture Trustee through the
Indenture Trustee's own willful misconduct, negligence or bad faith.

     The Issuer's payment obligations to the Indenture Trustee pursuant to this
Section shall survive the discharge of this Indenture or the earlier resignation
and removal of the Indenture Trustee. When the Indenture Trustee incurs expenses
after the occurrence of a Default specified in Section 5.01(d) or (e) with
respect to the Issuer, the expenses are intended to constitute expenses of
administration under Title 11 of the United States Code or any other applicable
Federal or state bankruptcy, insolvency or similar law.

     Section 6.08.  Replacement of Indenture Trustee. No resignation or removal
of the Indenture Trustee and no appointment of a successor Indenture Trustee
shall become effective until the acceptance of appointment by the successor
Indenture Trustee pursuant to this Section 6.08. The Indenture Trustee may
resign at any time by so notifying the Issuer. The Noteholders of a majority in
Outstanding Amount of the Controlling 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.

                                       34

<PAGE>

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

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

     If a successor Indenture Trustee does not take office within 60 days after
the retiring Indenture Trustee resigns or is removed, the retiring Indenture
Trustee, the Issuer or the Noteholders of a majority in Outstanding Amount of
the Controlling 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 6.07
shall continue for the benefit of the retiring Indenture Trustee.

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

     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

                                       35

<PAGE>

one or more Persons to act as a co-trustee or co-trustees, or separate trustee
or separate trustees, of all or any part of the Indenture Trust Estate, and to
vest in such Person or Persons, in such capacity and for the benefit of the
Noteholders, such title to the Indenture Trust Estate, or any part hereof, and,
subject to the other provisions of this Section, such powers, duties,
obligations, rights and trusts as the Indenture Trustee may consider necessary
or desirable. No such appointment shall relieve the Indenture Trustee of its
obligations hereunder. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
6.11 and no notice to Noteholders of the appointment of any co-trustee or
separate trustee shall be required under Section 6.08 hereof.

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

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

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

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

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

                                       36

<PAGE>

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. (a) The Indenture Trustee
shall at all times satisfy the requirements of TIA Section 310(a). The Indenture
Trustee shall have a combined capital and surplus of at least $50,000,000 as set
forth in its most recent published annual report of condition and it shall have
a long-term 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.

     (b)  Within ninety (90) days after ascertaining the occurrence of an Event
of Default which shall not have been cured or waived, unless authorized by the
TIA or the Commission, the Indenture Trustee shall resign with respect to the
Class A Notes, the Class B Notes and/or the Class C Notes in accordance with
Section 6.08 of this Indenture, and the Issuer shall appoint a successor
Indenture Trustee for two or all of such Classes, as applicable, so that there
will be separate Indenture Trustees for the Class A Notes, the Class B Notes and
the Class C Notes. In the event the Indenture Trustee fails to comply with the
terms of the preceding sentence, the Indenture Trustee shall comply with clauses
(ii) and (iii) of TIA Section 310(b).

     (c)  In the case of the appointment hereunder of a successor Indenture
Trustee with respect to any Class of Notes pursuant to this Section 6.11, the
Issuer, the retiring Indenture Trustee and the successor Indenture Trustee with
respect to such Class of Notes shall execute and deliver an indenture
supplemental hereto wherein each successor Indenture Trustee shall accept such
appointment and which (i) shall contain such provisions as shall be necessary or
desirable to transfer and confirm to, and to vest in, the successor Indenture
Trustee all the rights, powers, trusts and duties of the retiring Indenture
Trustee with respect to the Notes of the Class to which the appointment of such
successor Indenture Trustee relates, (ii) if the retiring Indenture Trustee is
not retiring with respect to all Classes of Notes, shall contain such provisions
as shall be deemed necessary or desirable to confirm that all the rights,
powers, trusts and duties of the retiring Indenture Trustee with respect to the
Notes of each Class as to which the retiring Indenture Trustee is not retiring
shall continue to be vested in the Indenture Trustee and (iii) shall add to or
change any of the provisions of this Indenture as shall be necessary to provide
for or facilitate the administration of the trusts hereunder by more than one
Indenture Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Indenture Trustees co-trustees of
the same trust and that each such Indenture Trustee shall be a trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Indenture Trustee; and upon the removal of the
retiring Indenture Trustee shall become effective to the extent provided herein.

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

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

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).

of information, including without limitation, the use of electronic mail or

fully tested by the Indenture Trustee and may not be completely reliable as to
stability, robustness and accuracy. Accordingly, the parties hereto acknowledge

not be relied upon as timely, accurate or complete and that the Indenture
Trustee shall have no liability hereunder in connection with such information
transmitted electronically. The parties hereto further acknowledge that any
systems, software or hardware utilized in posting or retrieving any such
information is utilized on an "as is" basis without representation or warranty
as to the intended uses of such systems, software or hardware. The Indenture
Trustee makes no representation or warranty that the systems and the related

software and hardware viruses, time bombs, logic bombs, Trojan horses, worms, or
other malicious computer instructions, intentional devices or techniques which
may cause a component or system to become erased, damaged, inoperable, or
otherwise incapable of being used in the manner to which it is intended, or
which would permit unauthorized access thereto. In the event such web site is
not available, the Indenture Trustee shall use reasonable efforts to distribute
such information in a timely manner to the intended recipients.

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

          (i)   supply to the Indenture Trustee, within 15 days after the Issuer
     is required to file the same with the Commission, copies of the annual
     reports and of the information, documents and other reports (or copies of
     such portions of any of the foregoing as the Commission may from time to
     time by rules and regulations prescribe) which the Issuer may be required
     to file with the Commission pursuant to Section 13 or 15(d) of the Exchange
     Act;

          (ii)  supply to the Indenture Trustee and file with the Commission in

     Commission such additional information, documents and reports with respect
     to compliance by the Issuer with the conditions and covenants of this
     Indenture as may be required from time to time by such rules and

                                  ARTICLE VIII

                      ACCOUNTS, DISBURSEMENTS AND RELEASES

     Section 8.01.  Collection of Money. Except as otherwise expressly provided
herein, the Indenture Trustee may demand payment or delivery of, and shall
receive and collect, directly and without intervention or assistance of any
fiscal agent or other intermediary, all money and other

                                       39

<PAGE>

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

     Section 8.02.  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 the
Certificateholders, the Trust Accounts as provided in Section 2.03 of the
Administration Agreement.

     (b)  On or before the Business Day preceding each Distribution Date, all
Available Funds with respect to the preceding Collection Period will be
deposited in the Collection Account as provided in Section 2.04 of the
Administration Agreement. On or before each Distribution Date, the Indenture
Trustee (or any other Paying Agent) shall make the deposits and distributions as
provided in Sections 2.07, 2.08(a), (b) and (c) of the Administration Agreement
(except as otherwise provided in Section 5.02 or Section 5.04(b)).

     Section 8.03.  General Provisions Regarding Accounts. (a) So long as no
Default shall have occurred and be continuing, all or a portion of the funds in
the Trust Accounts shall be invested in Eligible Investments and reinvested by
the Indenture Trustee upon Issuer Order, subject to the provisions of Section
2.03(b) of the Administration Agreement. All income or other gain from
investments of moneys deposited in the Trust Accounts shall be deposited by the
Indenture Trustee in the Collection Account, and any loss resulting from such
investments shall be charged to such Trust Account. The Issuer will not direct
the Indenture Trustee to make any investment of any funds or to sell any
investment held in any of the Trust Accounts unless the security interest
granted and perfected in such account will continue to be perfected in such
investment or the proceeds of such sale, in either case without any further
action by any Person, and, in connection with any direction to the Indenture
Trustee to make any such investment or sale, if requested by the Indenture
Trustee, the Issuer shall deliver to the Indenture Trustee an Opinion of
Counsel, acceptable to the Indenture Trustee, to such effect.

     (b)  Subject to Section 6.01(c), the Indenture Trustee shall not in any way
be held liable 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. The Indenture Trustee shall have
no liability in respect of losses incurred as a result of the liquidation of any
investment prior to its stated maturity or the failure of the Issuer to provide
timely written investment direction.

     (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

time as may be agreed by the Issuer and Indenture Trustee) on any Business Day;
or (ii) a Default shall have occurred and be continuing with respect to the
Notes but the Notes shall not have been declared due and payable pursuant to
Section 5.02, or, if such Notes shall have been declared due and payable
following an Event of Default, amounts collected or receivable from the
Indenture Trust Estate are being applied in accordance with Section 5.05 as if
there had not been such a declaration; then the Indenture Trustee shall invest
and reinvest funds in the Trust Accounts in the Eligible Investments described
in clause (d) of the definition thereof.

     Section 8.04.  Release of Indenture Trust Estate. (a) Subject to the
payment of its fees and expenses pursuant to Section 6.07, the Indenture Trustee
may, and when required by the provisions of this Indenture shall, execute
instruments to release property from the lien of this Indenture, or convey the
Indenture Trustee's interest in the same, in a manner and under circumstances
that are not inconsistent with the provisions of this Indenture. No party
relying upon an instrument executed by the Indenture Trustee as provided in this
Article VIII shall be bound to ascertain the Indenture Trustee's authority,
inquire into the satisfaction of any conditions precedent or see to the
application of any moneys.

     (b)  The Indenture Trustee shall, at such time as there are no Notes
Outstanding and all sums due the Indenture Trustee pursuant to Section 6.07 have
been paid, release any remaining portion of the Indenture Trust Estate that
secured the Notes from the lien of this Indenture and release to the Issuer or
any other Person entitled thereto any funds then on deposit in the Trust
Accounts. The Indenture Trustee shall release property from the lien of this
Indenture pursuant to this Section 8.04(b) only upon receipt of an Issuer
Request accompanied by an Officers' Certificate of the Issuer, an Opinion of
Counsel and (if required by the TIA) Independent Certificates in accordance with
TIA Sections 314(c) and 314(d)(1) meeting the applicable requirements of Section
11.01.

     (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
Article VI of the Depositor Sale Agreement, (ii) the Seller in accordance with
Article VI of the Seller Sale Agreement and (iii) the Servicer in accordance
with Section 3.05 of the Servicing Agreement and each Noteholder, by the
acceptance of a Note, consents to any such release.

     Section 8.05.  Opinion of Counsel. The Indenture Trustee shall receive at
least seven days' notice when requested by the Issuer to take any action
pursuant to Section 8.04(a), accompanied by copies of any instruments involved,
and the Indenture Trustee shall also require, except in connection with any
action contemplated by Section 8.04(c), as a condition to such action, an
Opinion of Counsel, in form and substance satisfactory to the Indenture Trustee,
stating the legal effect of any such action, outlining the steps required to
complete the same, and concluding that all conditions precedent to the taking of
such action have been complied with and such action will not materially and
adversely impair the security for the Notes or the rights of the Noteholders in
contravention of the provisions of this Indenture; provided, however, that such
Opinion of Counsel shall not be required to express an opinion as to the fair
value of the Indenture Trust Estate. Counsel rendering any such opinion may
rely, without independent investigation, on the accuracy and validity of any
certificate or other instrument delivered to the Indenture Trustee in connection
with any such action.

     Section 9.01.  Supplemental Indentures Without Consent of Noteholders. (a)

Indenture Act as in force at the date of the execution thereof), in form
satisfactory to the Indenture Trustee, for any of the following purposes:

          (i)   to correct or amplify the description of any property at any
     time subject to the lien of this Indenture, or better to assure, convey and
     confirm unto the Indenture Trustee any property subject or required to be
     subjected to the lien of this Indenture, or to subject to the lien of this
     Indenture additional property;

          (ii)  to evidence the succession, in compliance with the applicable
     provisions hereof, of another person to the Issuer, and the assumption by

     contained;

          (iii) to add to the covenants of the Issuer, for the benefit of the
     Noteholders, or to surrender any right or power herein conferred upon the

     shall not materially adversely affect the interests of the Noteholders;

          (vi)  to evidence and provide for the acceptance of the appointment

     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 qualification of this
     Indenture under the TIA or under any similar Federal statute hereafter
     enacted and to add to this Indenture such other provisions as may be
     expressly required by the TIA.

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

     (b)  The Issuer and the Indenture Trustee, when authorized by an Issuer
Order, may, also without the consent of any of the Noteholders but with prior
notice to the Rating Agencies,

                                       42

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 such action shall not,
as evidenced by an Opinion of Counsel, adversely affect in any material respect
the interests of any Noteholder.

     Section 9.02.  Supplemental Indentures With Consent of Noteholders. The
Issuer and the Indenture Trustee, when authorized by an Issuer Order, also may,
with prior notice to the Rating Agencies and with the consent of the 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, 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 such
     supplemental indenture, or the consent of the Noteholders of which is
     required for any waiver of compliance with certain provisions of this
     Indenture or certain defaults hereunder and their consequences provided for

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

                                       43

<PAGE>

     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 of any provisions for the mandatory redemption of the Notes
     contained herein; or

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

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

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

     Section 9.04.  Effect of Supplemental Indenture. Upon the execution of any
supplemental indenture pursuant to the provisions hereof, this Indenture shall
be and be deemed to be modified and amended in accordance therewith with respect
to the Notes affected thereby, and the respective rights, limitations of rights,
obligations, duties, liabilities and immunities under this Indenture of the
Indenture Trustee, the Issuer and the 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 9.05.  Conformity with Trust Indenture Act. Every amendment of this
Indenture and every supplemental indenture executed pursuant to this Article IX
shall conform to the requirements of the Trust Indenture Act as then in effect
so long as this Indenture shall then be qualified under the Trust Indenture Act.

     Section 9.06.  Reference in Notes to Supplemental Indentures. Notes
authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article IX may, and if required by the Indenture Trustee shall,
bear a notation in form approved by the Indenture

                                       44

<PAGE>

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.

                               REDEMPTION OF NOTES

     Section 10.01. Redemption. The Indenture Trustee shall, upon receipt of
written notice from the Servicer pursuant to Section 6.01 of the Administration

Section 6.01 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 up to the Outstanding Amount of the Notes and all accrued and
unpaid interest thereon. If amounts are to be paid to Noteholders pursuant to
this Section 10.01, 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 10.02. Form of Redemption Notice. Notice of redemption under
Section 10.01 shall be given by the Indenture Trustee by first-class mail,
postage prepaid, or by facsimile, mailed or transmitted on or prior to the
applicable Redemption Date to each Noteholder, as of the close of business on
the Record Date preceding the applicable Redemption Date, at such Noteholder's

     All notices of redemption shall state:

          (i)   the Redemption Date;

          (ii)  the Redemption Price; and

          (iii) the place where such Notes are to be surrendered for payment of
     the Redemption Price (which shall be the office or agency of the Issuer to
     be maintained as provided in Section 3.02).

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

     Section 10.03. Notes Payable on Redemption Date. The Notes or portions
thereof to be redeemed shall on the Redemption Date become due and payable at
the Redemption Price and (unless the Issuer shall default in the payment of the

<PAGE>

on the Redemption Price for any period after the date to which accrued interest
is calculated for purposes of calculating the Redemption Price.

     (a)  Every certificate or opinion with respect to compliance with a

     Section 11.01(a) or elsewhere in this Indenture, furnish to the Indenture
     Trustee and the Rating Agencies an Officers' Certificate of the Issuer

<PAGE>

          (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

     the dispositions of Collateral described in clauses (A), (B) or (C) above

     Section 11.02. Form of Documents Delivered to Indenture Trustee. In any
case where several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not necessary that all such matters be
certified by, or covered by the opinion of, only one such Person, or that they
be so certified or covered by only one document, but one such Person may certify
or give an opinion with respect to some matters, and one or more other such
Persons as to other matters, and any such Person may certify or give an opinion
as to such matters in one or several documents.

     Any certificate or opinion of an Authorized Officer of the Issuer may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate of an Authorized Officer or Opinion of Counsel
may be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of 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 11.03. Acts of Noteholders. (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Noteholders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Noteholders in person
or by agents duly appointed in writing; and except as herein otherwise expressly
provided such action shall become effective when such instrument or instruments
are delivered to the Indenture Trustee, and, where it is hereby expressly
required, to the Issuer. Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the "Act" of
the Noteholders signing such instrument or instruments. Proof of execution of
any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Section 6.01)
conclusive in favor of the Indenture Trustee and the Issuer, if made in the
manner provided in this Section.

                                       48

<PAGE>

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

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

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

     Section 11.04. Notices, etc., to Indenture Trustee, Issuer and Rating
Agencies. Any request, demand, authorization, direction, notice, consent, waiver
or Act of Noteholders or other documents provided or permitted by this Indenture
shall be in writing and if such request, demand, authorization, direction,
notice, consent, waiver or Act of Noteholders is to be made upon, given or
furnished to or filed with:

     (a)  The Indenture Trustee by any Noteholder, the Servicer, the
Administrator or by the Issuer shall be sufficient for every purpose hereunder
if made, given, furnished or filed in writing to or with the Indenture Trustee
at its Corporate Trust Office, or

     (b)  The Issuer by the Indenture Trustee or by any Noteholder shall be
sufficient for every purpose hereunder if in writing and mailed, first-class,
postage prepaid, to the Issuer addressed to: SLM Private Credit Student Loan

     Section 11.05. 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

<PAGE>

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 11.06. Alternate Payment and Notice Provisions. Notwithstanding any
provision of this Indenture or any of the Notes to the contrary, the Issuer may
enter into any agreement with any 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 11.07. Conflict with Trust Indenture Act. If any provision hereof
limits, qualifies or conflicts with another provision hereof that is required to
be included in this Indenture by any of the provisions of the Trust Indenture
Act, such required provision shall control.

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

     Section 11.08. Effect of Headings and Table of Contents. The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

     Section 11.09. Successors and Assigns. All covenants and agreements in this
Indenture and the Notes by the Issuer shall bind its successor and assigns,
whether so expressed or not. All agreements of the Indenture Trustee in this

representatives or accountants) of the Indenture Trustee.

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

     Section 11.11. Benefits of Indenture. Nothing in this Indenture or in the
Notes, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, and the Noteholders, and any other party
secured hereunder, and any other Person with an ownership interest in any part
of the Indenture Trust Estate, any benefit or any legal or equitable right,
remedy or claim under this Indenture.

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

     Section 11.13. Governing Law. THIS INDENTURE SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS
CONFLICT OF LAW PROVISIONS (OTHER THAN Section5-1401 OF THE NEW YORK GENERAL

HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

     Section 11.14. Counterparts. This Indenture may be executed in any number

but all such counterparts shall together constitute but one and the same
instrument.

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

the Issuer or (iii) any partner, owner, beneficiary, agent, officer, director or
employee of the Indenture Trustee or the Trustee in its individual capacity, any

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 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

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

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,

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

Trustee shall and shall cause its representatives to hold in confidence all such
information obtained from such examination or inspection except to the extent
disclosure may be required by law (and all reasonable applications for
confidential treatment are unavailing) and except to the extent that the
Indenture Trustee may reasonably determine that such disclosure is consistent
