                                    The Notes

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

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

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

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

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

                The Indenture Trustee shall upon Issuer Order authenticate and
deliver Notes for original issue in an aggregate principal amount of
$1,015,255,000. The aggregate principal amount of Notes outstanding at any time
may not exceed such amount except as provided in Section 2.5.

                                        4

<PAGE>

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

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

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

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

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

                                        5

<PAGE>

as herein provided. Upon any resignation of any Note Registrar, the Issuer shall
promptly appoint a successor or, if it elects not to make such an appointment,
assume the duties of Note Registrar.

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

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

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

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

                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

                                        6

<PAGE>

Registrar, which requirements include membership or participation in Securities
Transfer Agent's Medallion Program ("STAMP") or such other "signature guarantee
program" as may be determined by the Note Registrar in addition to, or in
substitution for, STAMP, all in accordance with the Exchange Act.

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

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

                SECTION 2.5 Mutilated, Destroyed, Lost or Stolen Notes. If (i)
any mutilated Note is surrendered to the Indenture Trustee, or the Indenture
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, and (ii) there is delivered to the Issuer and the Indenture Trustee
such security or indemnity as may be required by each of them to hold the Issuer
and the Indenture Trustee harmless, then, in the absence of notice to the
Issuer, the Note Registrar or the Indenture Trustee that such Note has been
acquired by a bona fide purchaser, and provided that the requirements of Section
8-405 of the UCC are met, the Issuer shall execute and upon its request the
Indenture Trustee shall authenticate and deliver, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Note, a replacement Note;
provided, however, that if any such destroyed, lost or stolen Note, but not a
mutilated Note, shall have become 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

                                        7

<PAGE>

any assignee of such Person, except a bona fide purchaser, and shall be entitled
to recover upon the security or indemnity provided therefor to the extent of any
loss, damage, cost or expense incurred by the Issuer or the Indenture Trustee in
connection therewith.

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

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

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

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

                SECTION 2.7 Payment of Principal and Interest; Note Interest
Shortfall.      (a)     The Notes shall accrue interest as provided in the forms
of Notes set forth in Exhibit A, and such interest shall be payable on each
Distribution Date as specified therein, subject to Section 3.1. Any installment
of interest or principal, if any, payable on any Note which is punctually paid
or duly provided for by the Issuer on the applicable Distribution Date shall be
paid to the Person in whose

                                        8

<PAGE>

name such Note (or one or more Predecessor Notes) is registered on the Record
Date by check mailed first-class, postage prepaid to such Person's address as it
appears on the Note Register on such Record Date, except that, unless Definitive
Notes have been issued pursuant to Section 2.12, with respect to Notes
registered on the Record Date in the name of the nominee of the applicable
Clearing Agency (initially, such nominee to be Cede & Co.), payment shall be
made by wire transfer in immediately available funds to the account designated
by such nominee and except for the final installment of principal payable with
respect to such Note on a Distribution Date or on the Note Final Maturity Date
for such Note which shall be payable as provided below. The funds represented by
any such checks returned undelivered shall be held in accordance with Section
3.3.

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

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

                SECTION 2.8 Cancellation. All Notes surrendered for payment,
registration of transfer, exchange or redemption shall, if surrendered to any
Person

                                        9

<PAGE>

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

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

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

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

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

                                       10

<PAGE>

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

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

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

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

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

                                       11

<PAGE>

that the continuation of a book-entry system through such Clearing Agency is no
longer in the best interests of the Note Owners, then the Indenture Trustee
shall cause such Clearing Agency to notify all Note Owners cleared, through such
Clearing Agency, of the occurrence of any such event and of the availability of
Definitive Notes to Note Owners requesting the same. Upon surrender to the
Indenture Trustee of the typewritten Notes representing the Book-Entry Notes by
a Clearing Agency, accompanied by registration instructions, the Issuer shall
execute and the Indenture Trustee shall authenticate the Definitive Notes in
accordance with the instructions of such Clearing Agency. None of the Issuer,
the Note Registrar or the Indenture Trustee shall be liable for any delay in
delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. Upon the issuance of Definitive
Notes, the Indenture Trustee shall recognize the holders of the Definitive Notes
as Noteholders.

                                   ARTICLE III

                                    Covenants

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

                SECTION 3.2 Maintenance of Office or Agency. The Issuer shall
maintain in the Borough of Manhattan, The City of New York, an office or agency
where Notes may be surrendered for registration of transfer or exchange, and
where notices and demands to or upon the Issuer in respect of the Notes and this
Indenture may be served. The Issuer hereby initially appoints the Indenture
Trustee to serve as its agent for the foregoing purposes. The Issuer shall give
prompt written notice to the Indenture Trustee of the location, and of any
change in the location, of any such

                                       12

<PAGE>

office or agency. If at any time the Issuer shall fail to maintain any such
office or agency or shall fail to furnish the Indenture Trustee with the address
thereof, such surrenders, notices and demands may be made or served at the
Corporate Trust Office, and the Issuer hereby appoints the Indenture Trustee as
its agent to receive all such surrenders, notices and demands.

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

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

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

        (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;

                                       13

<PAGE>

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

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

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

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

                Subject to applicable laws with respect to escheat of funds, any
money held by the Indenture Trustee or any Paying Agent in trust for the payment
of any amount due with respect to any Note and remaining unclaimed for two years
after such amount has become due and payable shall be discharged from such trust
and be paid to the Issuer on Issuer Request or if the Issuer has been 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

                                       14

<PAGE>

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

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

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

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

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

                (iii)   enforce any of the Collateral; or

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

                                       15

<PAGE>

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

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

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

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

        (b)     The Issuer may contract with other Persons to assist it in
performing its duties under this Indenture, and any performance of such duties
by a Person identified to the Indenture Trustee in an Officers' Certificate of
the Issuer shall be deemed to be action taken by the Issuer; provided, however,
the Issuer shall not be

                                       16

<PAGE>

liable for any acts of Persons with whom the Issuer has contracted with
reasonable care. Initially, the Issuer has contracted with the Servicer and the
Administrator to assist the Issuer in performing its duties under this
Indenture. The Issuer shall give written notice to the Indenture Trustee and
each Rating Agency of any such contract with any other Person.

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

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

        (e)     As promptly as possible after the giving of notice of
termination to the Servicer of the Servicer's rights and powers, pursuant to
Section 5.1 of the Servicing Agreement, or to the Administrator of the
Administrator's rights and powers, pursuant to Section 5.1 of the Administration
Agreement, the Issuer shall appoint a successor servicer (the "Successor
Servicer") or a successor administrator (the "Successor Administrator"),
respectively, and such Successor Servicer or Successor Administrator,

                                       17

<PAGE>

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; provided, however,
that nothing herein shall require or permit the Indenture Trustee to act as
Servicer, or otherwise service the Trust Student Loans, in violation of the
Higher Education Act. Upon delivery of any such notice to the Issuer, the Issuer
shall obtain a new servicer as the Successor Servicer under the Servicing
Agreement or a new administrator as the Successor Administrator under the
Administration Agreement, as the case may be. Any Successor Servicer or
Successor Administrator, other than the Indenture Trustee, shall (i) be an
established institution (A) that satisfies any requirements of the Higher
Education Act applicable to servicers and (B) whose regular business includes
the servicing or administration of student loans and (ii) enter into a servicing
agreement or an administration agreement, respectively, with the Issuer having
substantially the same provisions as the provisions of the Servicing Agreement
and the Administration Agreement, as applicable. If within 30 days after the
delivery of the notice referred to above, the Issuer shall not have obtained
such a new servicer or new administrator, as the case may be, the Indenture
Trustee may appoint, or may petition a court of competent jurisdiction to
appoint, a Successor Servicer or Successor Administrator; provided, however,
that such right to appoint or to petition for the appointment of any such
successor shall in no event relieve the Indenture Trustee from any obligations
otherwise imposed on it under the Basic Documents until such successor has in
fact assumed such appointment. In connection with any such appointment, the
Indenture Trustee may make such arrangements for the compensation of such
successor as it and such successor shall agree, subject to the limitations set
forth below and in the Servicing Agreement or Administration Agreement, as
applicable, and in accordance with Section 5.2 of the Servicing Agreement and
Section 5.2 of the Administration Agreement, the Issuer shall enter into an
agreement with such successor for the servicing or administration of the Trust
Student Loans (such agreement to be in form and substance satisfactory to the
Indenture Trustee). If the Indenture Trustee shall succeed as provided herein to

                                       18

<PAGE>

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.

Indenture Trustee, of all sums

                                       26

due and to become due thereon for principal and interest; but such moneys need

                SECTION 4.4 Auction of Trust Student Loans. Any Trust Student
Loans remaining in the Trust as of the end of the Collection Period immediately
preceding the earliest Distribution Date on which the Pool Balance is equal to
10% or less of the initial Pool Balance three business days prior to such
Distribution Date (the "Trust Auction Date") shall be offered for sale by the
Indenture Trustee unless the Servicer has exercised its option to purchase the
Trust Estate as described in Section 6.1A of the Administration Agreement with
respect to such Distribution Date. The Servicer will be deemed to have waived
such option if it fails to notify the Eligible Lender Trustee and the Indenture
Trustee of its exercise thereof in writing prior to the Indenture Trustee's
acceptance of a bid to purchase such Trust Student Loans; provided, however,
that there shall be no such offer for sale if the Indenture Trustee fails to
provide notice to the Servicer in accordance with this Section 4.4. The
Indenture Trustee shall provide written notice to the Servicer of any such offer
for sale at least 5 business days in advance of the Trust Auction Date. The
Indenture Trustee shall permit the Servicer or any of its Affiliates including
Sallie Mae 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

                                       27

<PAGE>

of the higher of the Minimum Purchase Amount and the fair market value of the
Trust Student Loans, the Indenture Trustee shall not consummate such sale. The
Indenture Trustee may consult, and, at the direction of the Depositor, shall
consult, with a financial advisor, including an underwriter of the Notes or the
Administrator, to determine if the fair market value of the Trust Student Loans
has been offered. The proceeds of any such sale will be applied in the order of
priority set forth in Section 5.4 (b). If the sale is not consummated in
accordance with the foregoing, the Indenture Trustee may, but shall not be under
any obligation to, solicit bids for sale of the Trust Student Loans with respect
to future Distribution Dates upon terms similar to those described above,
including the Servicer's waiver of its option to purchase the Trust Estate in
accordance with Section 6.1A of the Administration Agreement with respect to
each such future Distribution Date.

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

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

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

                                       29

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

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

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

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

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

any right consequent thereto.

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

                                       30

<PAGE>

collection, including the reasonable compensation, expenses, disbursements and
advances of the Indenture Trustee and its agents and counsel.

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

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

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

                (i)     to file and prove a claim or claims for the whole amount
        of principal and interest owing and unpaid in respect of the Notes and
        to file such

                                       31

<PAGE>

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

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

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

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

                                       32

<PAGE>

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

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

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

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

                                       33

<PAGE>

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

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

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

                                       34

        (b)     If the Indenture Trustee collects any money or property pursuant
to this Article V, it shall pay out the money or property (and other amounts
including amounts held on deposit in the Trust Account) held as Collateral for
the benefit of the Noteholders, net of liquidation costs associated with the
sale of the assets of the Trust, in the following order:

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

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

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

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

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

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

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

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

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

                                       35

<PAGE>

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

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

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

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

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

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

                                       36

<PAGE>

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

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

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

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

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

                SECTION 5.8 Restoration of Rights and Remedies. If the Indenture
Trustee or any Noteholder has instituted any Proceeding to enforce any right or
remedy under this Indenture 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.

                                       37

<PAGE>

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

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

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

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

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

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

                                       38

<PAGE>

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

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

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

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

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

                                       39

<PAGE>

such Note and in this Indenture (or, in the case of redemption, on or after the
Redemption Date).

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

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

                SECTION 5.16 Performance and Enforcement of Certain Obligations.

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

                                       40

<PAGE>

Administrator or the Servicer thereunder and the institution of legal or
administrative actions or proceedings to compel or secure performance by the
Depositor, Sallie Mae, the Administrator or the Servicer of each of their
obligations under the Sale Agreement, the Purchase Agreement, the Administration
Agreement and the Servicing Agreement, respectively.

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

                                   ARTICLE VI

                              The Indenture Trustee

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

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

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

                                       41

<PAGE>

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

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

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

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

                (iii)   the Indenture Trustee shall not be liable with respect
to any action it takes or omits to take in good faith in accordance with a
direction received by it pursuant to Section 5.11.

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

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

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

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

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

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

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

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

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

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

                                       43

<PAGE>

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

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

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

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

                SECTION 6.6 Reports by Indenture Trustee to Noteholders. The
Indenture Trustee shall deliver to each Noteholder (and to each Person who was a
Noteholder at any time during the applicable calendar year) such information as
may be required to enable such holder to prepare its Federal and state income
tax returns.

                                       44

<PAGE>

Within 60 days after each December 31 beginning with the December 31 following
the date of this Indenture, the Indenture Trustee shall mail to each Noteholder
a brief report as of such December 31 that complies with TIA Section 313(a) if
required by said section. The Indenture Trustee shall also comply with TIA
Section 313(b). A copy of each such report required pursuant to TIA Section
313(a) or (b) shall, at the time of such transaction to Noteholders, be filed by
the Indenture Trustee with the Commission and with each securities exchange, if
any, upon which the Notes are listed, provided that the Issuer has previously
notified the Indenture Trustee of such listing.

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

                The Issuer's payment obligations to the Indenture Trustee
pursuant to this Section shall survive the discharge of this Indenture. When the
Indenture Trustee

                                       45

<PAGE>

incurs expenses after the occurrence of a Default specified in Section 5.1(iv)
or (v) with respect to the Issuer, the expenses are intended to constitute
expenses of administration under Title 11 of the United States Code or any other
applicable Federal or state bankruptcy, insolvency or similar law.

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

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

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

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

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

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

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

                                       46

<PAGE>

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

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

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

                SECTION 6.9 Successor Indenture Trustee by Merger. If the
Indenture Trustee consolidates with, merges or converts into, or transfers all
or substantially all its corporate trust business or assets to, another
corporation or banking association, the resulting, surviving or transferee
corporation without any further act shall be the successor Indenture Trustee,
provided that such corporation or banking association shall be otherwise
qualified and eligible under Section 6.11. The Indenture Trustee shall provide
the Rating Agencies prior written notice of any such transaction.

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

                SECTION 6.10 Appointment of Co-Trustee or Separate Trustee.

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

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

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

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

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

                                       48

<PAGE>

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

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

                SECTION 6.11 Eligibility; Disqualification. The Indenture
Trustee shall at all times satisfy the requirements of TIA Section 310(a) and
the requirements of an "eligible lender" under 20 USC Section1085(d). The
Indenture Trustee shall have a combined capital and surplus of at least
$50,000,000 as set forth in its most recent published annual report of condition
and it shall have a long-term senior unsecured debt rating of not less than
investment grade by each of the Rating Agencies. The Indenture Trustee shall
comply with TIA Section 310(b), including the optional provision permitted by
the second sentence of TIA Section 310(b)(9); provided, however, that there
shall be excluded from the operation of TIA Section 310(b)(1) any indenture or
indentures under which other securities of the Issuer are outstanding if the
requirements for such exclusion set forth in TIA Section 310(b)(1) are met.

                SECTION 6.12 Preferential Collection of Claims Against 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.

Indenture Trustee may request in writing, within 30 days after receipt by the
Issuer of any such request, a list of similar form and content as of a date not
more than 10 days prior to the time such list is furnished; provided, however,
that so long as the Indenture Trustee is the Note Registrar, no such list shall
be required to be furnished.

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

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

        (b)     The Issuer, the Indenture Trustee and the Note Registrar shall

instruments furnished to the Indenture Trustee under the Basic Documents. The
Indenture Trustee shall furnish to the Noteholders promptly upon receipt thereof
from the Eligible Lender Trustee notice of any amendment of the Administration
Agreement pursuant to Section 8.5 of the Administration Agreement.

                SECTION 7.3 Reports by Issuer. (a) The Issuer shall:

                (i)     file with the Indenture Trustee, within 15 days after
the Issuer is required to file the same with the Commission, copies of the
annual reports and of the information, documents and other reports (or copies of

rules and regulations prescribe) which the Issuer may be required to file with

Trustee shall transmit by mail to all Noteholders described in TIA Section
313(c)) such summaries of any information, documents and reports required to be
filed by the Issuer pursuant to clauses (i) and (ii) of this Section 7.3(a) as

        (b)     Unless the Issuer otherwise determines, the fiscal year of the
Issuer shall end on December 31 of each year.

                      Accounts, Disbursements and Releases

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

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

                        (b)     On or before the Business Day preceding each
Distribution Date, all Available Funds with respect to the preceding Collection
Period will be deposited in the Collection Account as provided in Section 2.4 of
the Administration Agreement. On or before each Distribution Date, the Indenture
Trustee (or any other Paying Agent) shall make the deposits and distributions as
provided in Sections 2.7, 2.8.1 and 2.8.2 of the Administration Agreement.

                SECTION 8.3 General Provisions Regarding Accounts. (a) So long
as no Default shall have occurred and be continuing, all or a portion of the
funds in the Trust Accounts shall be invested in Eligible Investments and
reinvested by the Indenture Trustee upon Issuer Order, subject to the provisions
of Section 2.3B 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

                                       52

<PAGE>

Collection Account, and any loss resulting from such investments shall be
charged to such Trust Account. All income or other gain from investments of
moneys deposited in the Capitalized Interest Account, if any, shall be deposited
by the Indenture Trustee in the Capitalized Interest Account, and any loss
resulting from such investments shall be charged to the Capitalized Interest
Account. The Issuer will not direct the Indenture Trustee to make any investment
of any funds or to sell any investment held in any of the Trust Accounts unless
the security interest granted and perfected in such account will continue to be
perfected in such investment or the proceeds of such sale, in either case
without any further action by any Person, and, in connection with any direction
to the Indenture Trustee to make any such investment or sale, if requested by
the Indenture Trustee, the Issuer shall deliver to the Indenture Trustee an
Opinion of Counsel, acceptable to the Indenture Trustee, to such effect.

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

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

                SECTION 8.4 Release of Indenture Trust Estate. (a) Subject to
the payment of its fees and expenses pursuant to Section 6.7, the Indenture
Trustee may, and when required by the provisions of this Indenture shall,
execute instruments to release property from the lien of this Indenture, or
convey the Indenture Trustee's interest in the same, in a manner and under
circumstances that are not inconsistent

                                       53

<PAGE>

with the provisions of this Indenture. No party relying upon an instrument
executed by the Indenture Trustee as provided in this Article VIII shall be
bound to ascertain the Indenture Trustee's authority, inquire into the
satisfaction of any conditions precedent or see to the application of any
moneys.

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

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

                SECTION 8.5 Opinion of Counsel. The Indenture Trustee shall
receive at least seven days' notice when requested by the Issuer to take any
action pursuant to Section 8.4(a), accompanied by copies of any instruments
involved, and the Indenture Trustee shall also require, except in connection
with any action contemplated by Section 8.4(c), as a condition to such action,
an Opinion of Counsel, in form and substance satisfactory to the Indenture
Trustee, stating the legal effect of any such action, outlining the steps
required to complete the same, and concluding that all conditions precedent to
the taking of such action have been complied with and such action will not
materially and adversely impair the security for the Notes or the rights of the
Noteholders in contravention of the provisions of this Indenture; provided,
however, that such Opinion of Counsel shall not be required to express an
opinion as to the fair value of the Indenture Trust Estate. Counsel rendering
any such

                                       54

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 9.1 Supplemental Indentures Without Consent of
Noteholders. Without the consent of any Noteholders but with prior notice to the
Rating Agencies, the Issuer and the Indenture Trustee, when authorized by an
Issuer Order, at any time and from time to time, may enter into one or more
indentures supplemental hereto (which shall conform to the provisions of the
Trust 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 any such successor of the covenants of the Issuer herein and in
the Notes 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
Issuer;

                (iv)    to convey, transfer, assign, mortgage or pledge any
property to the Indenture Trustee;

                (v)     to cure any ambiguity, to correct or supplement any
provision herein or in any supplemental indenture which may be inconsistent with
any other provision herein or in any supplemental indenture or to make any other

in any supplemental indenture; provided that such action shall not materially
adversely affect the interests of the Noteholders;

                                       55

<PAGE>

                (vi)    to evidence and provide for the acceptance of the
appointment hereunder by a successor trustee with respect to the Notes and to
add to or change any of the provisions of this Indenture as shall be necessary
to facilitate the administration of the trusts hereunder by more than one
trustee, pursuant to the requirements of Article VI; or

                (vii) to modify, eliminate or add to the provisions of this
Indenture to such extent as shall be necessary to effect the 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, 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 9.2 Supplemental Indentures with Consent of Noteholders.
The Issuer and the Indenture Trustee, when authorized by an Issuer Order, also
may, with prior notice to the Rating Agencies and with the consent 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:

                                       56

<PAGE>

                (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 in this
Indenture;

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

                (iv)    reduce the percentage of the Outstanding Amount of the
Notes required to direct the Indenture Trustee to direct the Issuer to sell or
liquidate the Indenture Trust Estate pursuant to Section 5.4;

                (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 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

                                       57

<PAGE>

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

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

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

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

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

                                       58

<PAGE>

deemed to be part of the terms and conditions of this Indenture for any and all
purposes.

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

                SECTION 9.6 Reference in Notes to Supplemental Indentures. Notes
authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article IX may, and if required by the Indenture Trustee shall,
bear a notation in form approved by the Indenture Trustee as to any matter
provided for in such supplemental indenture. If the Issuer or the Indenture
Trustee shall so determine, new Notes so modified as to conform, in the opinion
of the Indenture Trustee and the Issuer, to any such supplemental indenture may
be prepared and executed by the Issuer and authenticated and delivered by the
Indenture Trustee in exchange for Outstanding Notes.

                                    ARTICLE X

                               Redemption of Notes

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

                SECTION 10.2 Form of Redemption Notice. Notice of redemption
under Section 10.1 shall be given by the Indenture Trustee by first-class mail,
postage

                                       59

<PAGE>

prepaid, or by facsimile, mailed or transmitted on or prior to the applicable
Redemption Date to each Noteholder, as of the close of business on the Record
Date preceding the applicable Redemption Date, at such Noteholder's address or
facsimile number appearing in the Note Register.

                All notices of redemption shall state:

                (i)     the Redemption Date;

                (ii)    the Redemption Price; and

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

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

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

                                   ARTICLE XI

                                  Miscellaneous

                SECTION 11.1 Compliance Certificates and Opinions, etc. Upon any
application or request by the Issuer to the Indenture Trustee to take any action
under any provision of this Indenture, the Issuer shall furnish to the Indenture
Trustee and the Rating Agencies (i) an Officers' Certificate of the Issuer
stating that all conditions precedent, if any, provided for in this Indenture
relating to the proposed

                                       60

<PAGE>

action have been complied with, (ii) an Opinion of Counsel stating that in the
opinion of such counsel all such conditions precedent, if any, have been
complied with and (iii) (if required by the TIA) an Independent Certificate from
a firm of certified public accountants meeting the applicable requirements of
this Section, except that, in the case of any such application or request as to
which the furnishing of such documents is specifically required by any provision
of this Indenture, no additional certificate or opinion need be furnished.

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

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

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

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

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

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

                                       61

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

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

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

                (v)     Notwithstanding Section 2.9 or any other provision of
this Section, the Issuer may, without compliance with the requirements of the
other provisions of this Section, (A) collect, liquidate, sell or otherwise
dispose of Trust

                                       62

<PAGE>

Student Loans as and to the extent permitted or required by the Basic Documents,
(B) make cash payments out of the Trust Accounts as and to the extent permitted
or required by the Basic Documents and (C) convey to the Depositor, the Servicer
or another eligible lender those specified Trust Student Loans as and to the
extent permitted or required by and in accordance with Section 8.4(c) hereof and
Section 6 of the Sale Agreement, Section 3.5 of the Servicing Agreement or
Section 3.11E of the Servicing Agreement, respectively, so long as the Issuer
shall deliver to the Indenture Trustee every six months, commencing December 31,
2003, an Officers' Certificate of the Issuer stating that all the dispositions
of Collateral described in clauses (A), (B) or (C) above that occurred during
the immediately preceding six calendar months were in the ordinary course of the
Issuer's business and that the proceeds thereof were applied in accordance with
the Basic Documents.

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

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

                Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments

                                       63

<PAGE>

under this indenture, they may, but need not, be consolidated and form one
instrument.

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

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

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

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

        (d)     Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Noteholder of any Notes shall bind the Noteholder
of every

                                       64

<PAGE>

Note issued upon registration of transfer thereof or in exchange therefor or in
lieu thereof, in respect of anything done, omitted or suffered to be done by the
Indenture Trustee or the Issuer in reliance thereon, whether or not notation of
such action is made upon such Note.

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

        (a)     The Indenture Trustee by any Noteholder, the Servicer, the

        (b)     The Issuer by the Indenture Trustee or by any Noteholder shall
be sufficient for every purpose hereunder if in writing and mailed, first-class,
postage prepaid, to the Issuer addressed to: SLM Student Loan Trust 2003-6, in
care of Chase Manhattan Bank USA, National Association, Christiana Center/OPS4,

Operations, or any other address previously furnished in writing to the
Indenture Trustee by the Issuer or the Administrator. The Issuer shall promptly
transmit any notice received by it from the Noteholders to the Indenture
Trustee.

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

as shall be designated by written notice to the other parties.

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

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

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

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

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

to such Noteholder, that is different from the methods provided for in this
Indenture for such

                                       66

payments or notices. The Issuer will furnish to the Indenture Trustee a copy of
each such agreement and the Indenture Trustee will cause payments to be made and
notices to be given in accordance with such agreements.

                SECTION 11.7 Conflict with Trust Indenture Act. If any provision

successor and assigns, whether so expressed or not. All agreements of the
Indenture Trustee in this Indenture shall bind the successors, co-trustees and
agents (excluding any legal representatives or accountants) of the Indenture
Trustee.

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

                SECTION 11.11 Benefits of Indenture. Nothing in this Indenture
or in the Notes, express or implied, shall give to any Person, other than the
parties hereto and their successors hereunder, and the Noteholders, and any
other party 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
Obligations Law), and the obligations, rights and remedies of the parties
hereunder shall be determined in accordance with such laws.

                SECTION 11.14 Counterparts. This Indenture may be executed in

same instrument.

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

                SECTION 11.16 Trust Obligations. No recourse may be taken,
directly or indirectly, with respect to the obligations of the Issuer, the
Depositor, the Administrator, the Servicer, the Eligible Lender Trustee or the
Indenture Trustee on the Notes or under this Indenture or any certificate or
other writing delivered in connection herewith or therewith, against (i) the

the Indenture Trustee and the Eligible Lender Trustee have no such obligations
in their individual capacity) and except that any such partner, owner or
beneficiary shall be fully liable, to the extent provided by applicable law, for
any unpaid consideration for stock, unpaid capital contribution or failure to
pay any installment or call owing to such entity. For all purposes of this
Indenture, in the performance of any duties or obligations of the Issuer
hereunder, the Eligible Lender Trustee shall be subject to, and entitled to the
benefits of, the terms and provisions of Article VI, VII and VIII of the Trust
Agreement.

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

                SECTION 11.18 Inspection. The Issuer agrees that, on reasonable
prior notice, it shall permit any representative of the Indenture Trustee,
during the Issuer's normal business hours, to examine all the books of account,

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

                FLOATING RATE CLASS A-1 STUDENT LOAN-BACKED NOTES

                SLM Student Loan Trust 2003-6, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to Cede & Co., or
registered assigns, the principal sum of [Note Face Amount] payable on each
Distribution Date in an amount equal to the aggregate amount, if any, payable to
Class A-1 Noteholders on such Distribution Date in respect of principal of the
Notes pursuant to Section 3.1 of the Indenture dated as of June 1, 2003, among
the Issuer, Chase Manhattan Bank USA, National Association, a Delaware banking
corporation, as Eligible Lender Trustee on behalf of the Issuer, and The Bank of
New York, a New York banking corporation, as Indenture Trustee (the "Indenture
Trustee") (capitalized terms used but not defined herein being defined in
Appendix A to the Indenture, which also contains rules as to usage that shall be
applicable herein); provided, however, that the entire unpaid principal amount
of this Note shall be due and payable on June 16, 2008 (the "Class A-1 Maturity
Date").

                The Issuer shall pay interest on this Note at the rate per annum
equal to the Class A-1 Rate (as defined on the reverse hereof), on each
Distribution Date until the principal of this Note is paid or made available for
payment, on the principal amount of this Note outstanding on the preceding
Distribution Date (after giving effect to all payments of principal made on the
preceding Distribution Date), subject to certain limitations contained in
Section 3.1 of the Indenture. Interest on this Note shall accrue from and
including the preceding Distribution Date (or, in the case of the first Accrual
Period, the Closing Date) to but excluding the following Distribution Date (each
an "Accrual Period"). Interest shall be calculated on the basis of the actual
number of days elapsed in each Accrual Period divided by 360. Such principal of
and interest on this Note shall be paid in the manner specified on the reverse
hereof.

                The principal of and interest on this Note are payable in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. All payments made by the
Issuer with respect to this Note shall be applied first to interest due and
payable on this Note as provided above and then to the unpaid principal of this
Note.

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

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

                                [REVERSE OF NOTE]

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

                The Class A-1 Notes are and will be equally and ratably secured
by the Collateral pledged as security therefor as provided in the Indenture. The
Class A-1 Notes are prior in order of principal payment to the Class A-2, Class
A-3, Class A-4 and Class B Notes and senior to the Class B Notes as and to the
extent provided in the Indenture.

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

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

                Interest on the Class A-1 Notes shall be payable on each
Distribution Date on the principal amount outstanding of the Class A-1 Notes
until the principal amount thereof is paid in full, at a rate per annum equal to
the Class A-1 Rate. The "Class A-1 Rate" for each Accrual Period shall be equal
to Three-Month LIBOR as determined on the second Business Day before the
beginning of that Accrual Period plus 0.00%. For the initial Accrual Period, the
Class A-1 Rate shall mean the rate determined by the following formula: x +
[10/31 * (y-x)] plus 0.00% where: x = Three-Month LIBOR, and y = Four-Month
LIBOR, as determined on the second Business Day before the beginning of the
Accrual Period.

<PAGE>

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

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

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

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

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

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

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

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

                The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the rights of the Noteholders under the Indenture
at any time by the Issuer with the consent of the Noteholders representing a

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

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

circumstances, to merge or consolidate, subject to the rights of the Indenture
Trustee and the Noteholders under the Indenture.

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

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

                Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither The Bank of New York, in its
individual capacity, Chase Manhattan Bank USA, National Association in its
individual capacity, any owner of a beneficial interest in the Issuer, nor any
of their respective partners, beneficiaries, agents, officers, directors,
employees or successors or assigns shall be personally liable for, nor shall

or performance of, or omission to perform, any of the covenants, obligations or
indemnifications contained in this Note or the Indenture; it

                SLM Student Loan Trust 2003-6, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the principal sum of [Note Face Amount] payable on each
Distribution Date in an amount equal to the aggregate amount, if any, payable to
Class A-2 Noteholders on such Distribution Date in respect of principal of the
Notes pursuant to Section 3.1 of the Indenture dated as of June 1, 2003, among
the Issuer, Chase Manhattan Bank USA, National Association, a Delaware banking
corporation, as Eligible Lender Trustee on behalf of the Issuer, and The Bank of
New York, a New York banking corporation, as Indenture Trustee (the "Indenture
Trustee") (capitalized terms used but not defined herein being defined in
Appendix A to the Indenture, which also contains rules as to usage that shall be
applicable herein); provided, however, that the entire unpaid principal amount
of this Note shall be due and payable on March 15, 2011 (the "Class A-2 Maturity
Date").

                The Issuer shall pay interest on this Note at the rate per annum
equal to the Class A-2 Rate (as defined on the reverse hereof), on each
Distribution Date until the principal of this Note is paid or made available for
payment, on the principal amount of this Note outstanding on the preceding
Distribution Date (after giving effect to all payments of principal made on the
preceding Distribution Date), subject to certain limitations contained in
Section 3.1 of the Indenture. Interest on this Note shall accrue from and
including the preceding Distribution Date (or, in the case of the first Accrual
Period, the Closing Date) to but excluding the following Distribution Date (each
an "Accrual Period"). Interest shall be calculated on the basis of the actual
number of days elapsed in each Accrual Period divided by 360. Such principal of
and interest on this Note shall be paid in the manner specified on the reverse
hereof.

                The principal of and interest on this Note are payable in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. All payments made by the
Issuer with respect to this Note shall be applied first to interest due and
payable on this Note as provided above and then to the unpaid principal of this
Note.

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

                Unless the certificate of authentication hereon has been
executed by the Indenture Trustee whose name appears below by manual signature,
this Note shall not be entitled to any benefit under the Indenture referred to

                                [REVERSE OF NOTE]

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

                The Class A-2 Notes are and will be equally and ratably secured
by the Collateral pledged as security therefor as provided in the Indenture. The
Class A-1 Notes are prior in order of principal payment to the Class A-2 Notes
and the Class A-2 Notes are prior in order of principal payment to the Class
A-3, Class A-4 and Class B Notes and senior to the Class B Notes as and to the
extent provided in the Indenture.

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

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

                Interest on the Class A-2 Notes shall be payable on each
Distribution Date on the principal amount outstanding of the Class A-2 Notes
until the principal amount thereof is paid in full, at a rate per annum equal to
the Class A-2 Rate. The "Class A-2 Rate" for each Accrual Period shall be equal
to Three-Month LIBOR as determined on the second Business Day before the
beginning of that Accrual Period plus 0.03%. For the initial Accrual Period, the
Class A-2 Rate shall mean the rate determined by the following formula: x +
[10/31 * (y-x)] plus 0.03%

                                        4

<PAGE>

where: x = Three-Month LIBOR, and y = Four-Month LIBOR, as determined on the
second Business Day before the beginning of the Accrual Period.

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

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

                As provided in the Indenture and subject to certain limitations
set forth therein, the transfer of this Note may be registered on the Note
Register upon surrender of this Note for registration of transfer at the office
or agency designated by the Issuer pursuant to the Indenture, duly endorsed by,
or accompanied by a written instrument of transfer in form satisfactory to the
Indenture Trustee duly executed by, the Noteholder hereof or his attorney duly
authorized in writing, with such signature guaranteed by an "eligible guarantor
institution" meeting the requirements of the Note Registrar, which requirements
include membership or participation in Securities Transfer Agent's Medallion
Program ("STAMP") or such other "signature guarantee program" as may be
determined by the Note Registrar in addition to, or in substitution for, STAMP
(all in accordance with the Exchange Act), and such other documents as the
Indenture Trustee may require, and thereupon one or more new Notes of authorized
denominations and in the same aggregate principal amount shall be issued to the
designated transferee or transferees.

                                        5

No service charge will be charged for any registration of transfer or exchange
of this Note, but the transferor may be required to pay a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any such registration of transfer or exchange.

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

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

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

                Prior to the due presentment for registration of transfer of
this Note, the Issuer, the Indenture Trustee and any agent of the Issuer or the
Indenture Trustee may treat the Person in whose name this Note (as of the day of
determination or as of such other date as may be specified in the Indenture) is
registered as the owner hereof for all purposes whether or not this Note be

                                        6

<PAGE>

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

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

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

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

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

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

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

                Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither The Bank of New York, in its
individual capacity, Chase Manhattan Bank USA, National Association in its
individual capacity, any owner of a beneficial interest in the Issuer, nor any
of their respective partners, beneficiaries, agents, officers, directors,

employees or successors or assigns shall be personally liable for, nor shall
recourse be had to any of them for, the payment of principal of or interest on,
or performance of, or omission to perform, any of the covenants, obligations or
indemnifications contained in this Note or the Indenture; it being expressly
understood that said covenants, obligations and indemnifications have been made
by the Eligible Lender Trustee for the sole purposes of binding the interests of
the Eligible Lender Trustee in the assets of the Issuer. The Noteholder of this
Note by the acceptance hereof agrees that, except as expressly provided in the
Basic Documents, in the case of an Event of Default under the Indenture, the
Noteholder shall have no claim against any of the foregoing for any deficiency,
loss or claim therefrom; provided, however, that nothing contained herein shall
be taken to prevent recourse to, and enforcement against, the assets of the
Issuer for any and all liabilities, obligations and undertakings contained in
the Indenture or in this Note.

                SLM Student Loan Trust 2003-6, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the principal sum [Note Face Amount] payable on each
Distribution Date in an amount equal to the aggregate amount, if any, payable to
Class A-3 Noteholders on such Distribution Date in respect of principal of the
Notes pursuant to Section 3.1 of the Indenture dated as of June 1, 2003, among
the Issuer, Chase Manhattan Bank USA, National Association, a Delaware banking
corporation, as Eligible Lender Trustee on behalf of the Issuer, and The Bank of
New York, a New York banking corporation, as Indenture Trustee (the "Indenture
Trustee") (capitalized terms used but not defined herein being defined in
Appendix A to the Indenture, which also contains rules as to usage that shall be
applicable herein); provided, however, that the entire unpaid principal amount
of this Note shall be due and payable on September 17, 2012 (the "Class A-3
Maturity Date").

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

                The principal of and interest on this Note are payable in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. All payments made by the
Issuer with respect to this Note shall be applied first to interest due and
payable on this Note as provided above and then to the unpaid principal of this
Note.

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

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

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

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

                Interest on the Class A-3 Notes shall be payable on each
Distribution Date on the principal amount outstanding of the Class A-3 Notes
until the principal amount thereof is paid in full, at a rate per annum equal to
the Class A-3 Rate. The "Class A-3 Rate" for each Accrual Period shall be equal
to Three-Month LIBOR as determined on the second Business Day before the
beginning of that Accrual Period plus 0.09%. For the initial Accrual Period, the
Class A-3 Rate shall mean the rate determined by the following formula: x +
[10/31 * (y-x)] plus 0.09% where: x = Three-Month LIBOR, and y = Four-Month
LIBOR, as determined on the second Business Day before the beginning of the
Accrual Period.

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

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

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

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

Indenture or any certificate or other writing delivered in connection therewith,
against (i) the Indenture Trustee or the Eligible Lender Trustee in its
individual capacity, (ii) any owner of a beneficial interest in the Issuer or

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

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

or other proceedings under any United States Federal or state bankruptcy or
similar law in connection with any obligations relating to the Notes, the
Indenture or the other Basic Documents.

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

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

provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the rights of the

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

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

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

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

Note or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and interest on
this Note at the times, place, and rate, and in the coin or currency, herein
prescribed.

                Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither The Bank of New York, in its
individual capacity, Chase Manhattan Bank USA, National Association in its
individual capacity, any owner of a beneficial interest in the Issuer, nor any
of their respective partners, beneficiaries, agents, officers, directors,

recourse be had to any of them for, the payment of principal of or interest on,
or performance of, or omission to perform, any of the covenants, obligations or
indemnifications contained in this Note or the Indenture; it being expressly
understood that said covenants, obligations and indemnifications have been made
by the Eligible Lender Trustee for the sole purposes of binding the interests of
the Eligible Lender Trustee in the assets of the Issuer. The Noteholder of this
Note by the acceptance hereof

                SLM Student Loan Trust 2003-6, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the principal sum of [Note Face Amount] payable on each
Distribution Date in an amount equal to the aggregate amount, if any, payable to
Class A-4 Noteholders on such Distribution Date in respect of principal of the
Notes pursuant to Section 3.1 of the Indenture dated as of June 1, 2003, among
the Issuer, Chase Manhattan Bank USA, National Association, a Delaware banking
corporation, as Eligible Lender Trustee on behalf of the Issuer, and The Bank of
New York, a New York banking corporation, as Indenture Trustee (the "Indenture
Trustee") (capitalized terms used but not defined herein being defined in
Appendix A to the Indenture, which also contains rules as to usage that shall be
applicable herein); provided, however, that the entire unpaid principal amount
of this Note shall be due and payable on December 17, 2018 (the "Class A-4

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

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

payable on this Note as provided above and then to the unpaid principal of this
Note.

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

                Unless the certificate of authentication hereon has been
executed by the Indenture Trustee whose name appears below by manual signature,
this Note shall not be entitled to any benefit under the Indenture referred to

                                [REVERSE OF NOTE]

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

                The Class A-4 Notes are and will be equally and ratably secured
by the Collateral pledged as security therefor as provided in the Indenture. The
Class A-1 Notes, Class A-2 Notes and Class A-3 Notes are prior in order of
principal payment to the Class A-4 Notes and the Class A-4 Notes are prior in
order principal payment to the Class B Notes and senior to the Class B Notes as
and to the extent provided in the Indenture.

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

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

                Interest on the Class A-4 Notes shall be payable on each
Distribution Date on the principal amount outstanding of the Class A-4 Notes
until the principal amount thereof is paid in full, at a rate per annum equal to
the Class A-4 Rate. The "Class A-4 Rate" for each Accrual Period shall be equal
to Three-Month LIBOR as determined on the second Business Day before the
beginning of that Accrual Period plus 0.20%. For the initial Accrual Period, the
Class A-4 Rate shall mean the rate determined by the following formula: x +
[10/31 * (y-x)] plus 0.20% where: x = Three-Month LIBOR, and y = Four-Month
LIBOR, as determined on the second Business Day before the beginning of the
Accrual Period.

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

Trustee's agent appointed for such purposes located in the Borough of Manhattan,
The City of New York.

set forth therein, the transfer of this Note may be registered on the Note
Register upon surrender of this Note for registration of transfer at the office
or agency designated by the Issuer pursuant to the Indenture, duly endorsed by,
or accompanied by a written instrument of transfer in form satisfactory to the
Indenture Trustee duly executed by, the Noteholder hereof or his attorney duly
authorized in writing, with such signature guaranteed by an "eligible guarantor
institution" meeting the requirements of the Note Registrar, which requirements
include membership or participation in Securities Transfer Agent's Medallion

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

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

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

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

                The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the rights of the Noteholders under the Indenture
at any time by the Issuer with the consent of the Noteholders

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

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

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

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

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

Note or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and interest on
this Note at the times, place, and rate, and in the coin or currency, herein
prescribed.

                Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither The Bank of New York, in its
individual capacity, Chase Manhattan Bank USA, National Association in its
individual capacity, any owner of a beneficial interest in the Issuer, nor any
of their respective partners, beneficiaries, agents, officers, directors,
employees or successors or assigns shall be personally liable for, nor shall
recourse be had to any of them for, the payment of principal of or interest on,
or performance of, or omission to perform, any of the covenants, obligations or
indemnifications contained in this Note or the Indenture; it being expressly
understood that said covenants, obligations and indemnifications have been made
by the Eligible Lender Trustee for the sole purposes of binding the interests of

                SLM Student Loan Trust 2003-6, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the principal sum of [Note Face Amount] payable on each
Distribution Date in an amount equal to the aggregate amount, if any, payable to
Class B Noteholders on such Distribution Date in respect of principal of the
Notes pursuant to Section 3.1 of the Indenture dated as of June 1, 2003, among
the Issuer, Chase Manhattan Bank USA, National Association, a Delaware banking
corporation, as Eligible Lender Trustee on behalf of the Issuer, and The Bank of
New York, a New York banking corporation, as Indenture Trustee (the "Indenture
Trustee") (capitalized terms used but not defined herein being defined in
Appendix A to the Indenture, which also contains rules as to usage that shall be
applicable herein); provided, however, that the entire unpaid principal amount
of this Note shall be due and payable on March 17, 2025 (the "Class B Maturity
Date").

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

                The principal of and interest on this Note are payable in such
coin or currency of the United States of America as at the time of payment is

payable on this Note as provided above and then to the unpaid principal of this
Note.

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

executed by the Indenture Trustee whose name appears below by manual signature,
this Note shall not be entitled to any benefit under the Indenture referred to

                                [REVERSE OF NOTE]

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

                The Class B Notes are and will be equally and ratably secured by
the Collateral pledged as security therefor as provided in the Indenture. The
Class A-1, Class A-2 Notes, Class A-3 Notes and Class A-4 Notes are prior in
order of principal payment, and are senior, to the Class B Notes as and to the
extent provided in the Indenture.

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

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

                Interest on the Class B Notes shall be payable on each
Distribution Date on the principal amount outstanding of the Class B Notes until
the principal amount thereof is paid in full, at a rate per annum equal to the
Class B Rate. The "Class B Rate" for each Accrual Period shall be equal to
Three-Month LIBOR as determined on the second business day before the beginning
of that Accrual Period plus 0.53%. For the initial Accrual Period, the Class B
Rate shall mean the rate determined by the following formula: x + [10/31 *
(y-x)] plus 0.53% where: x = Three-Month LIBOR, and y = Four-Month LIBOR, as
determined on the second Business Day before the beginning of the Accrual
Period.

<PAGE>

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

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

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

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

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

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

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

                The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the rights of the Noteholders under the Indenture
at any time by the Issuer with the consent of the

                                        6

<PAGE>

Noteholders representing a majority of the Outstanding Amount of all Notes at
the time outstanding. The Indenture also contains provisions permitting the
Noteholders representing specified percentages of the Outstanding Amount of the
Notes, on behalf of all the Noteholders, to waive compliance by the Issuer with
certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the holder of
this Note (or any one of more Predecessor Notes) shall be conclusive and binding
upon such holder and upon all future holders of this Note and of any Note issued
upon registration of transfer hereof or in exchange hereof or in lieu hereof
whether or not notation of such consent or waiver is made upon this Note. The
Indenture also permits the Indenture Trustee to amend or waive certain terms and

Ladies and Gentlemen:

extent there are no additional Underwriters listed on Schedule II other than

         1. REPRESENTATIONS AND WARRANTIES. The Company represents and warrants
to, and agrees with, each Underwriter as set forth below in this Section 1 that:

         (A) SHELF PROCEDURE ELIGIBILITY. The Company meets the eligibility
requirements to use the Shelf Procedures and to file a short form prospectus
with the Reviewing Authority; a preliminary short form shelf prospectus and a
final short form shelf prospectus have been filed with the Reviewing Authority
and the Company has informed the Reviewing Authority that it is the principal
jurisdiction regulating the offering of the Securities; a receipt has been
obtained from the Reviewing Authority in respect of such short form shelf
prospectus and any amendment thereto; no order suspending the distribution of
the Securities has been issued by the Reviewing Authority and no proceeding for
that purpose has, to the best of the Company's knowledge, been initiated or
threatened by the Reviewing Authority;

         (B) REGISTRATION REQUIREMENT COMPLIANCE. The Company meets the general
eligibility requirements for use of Form F-9 under the Act, has filed a
registration statement on Form F-10 and a post-effective amendment to that Form
F-10 on Form F-9 (File No. 333-101140) in respect of the Securities and an
appointment of agent for service of process on Form F-X (the "FORM F-X") in
conjunction with the filing of such registration statement with the Commission
and has caused the Trustee to prepare and file with the Commission a Statement
of Eligibility and Qualification on Form T-1 (the "FORM T-1"); such registration
statement and any post-effective amendment thereto, in each case including the
Basic Prospectus (with such deletions therefrom and additions thereto as are
permitted or required by Form F-9 and the applicable rules and regulations of
the Commission), each in the form heretofore delivered or to be delivered to the
Representative and, including exhibits to such registration statement and any
documents incorporated by reference in the prospectus contained therein, for
delivery by them to each of the other Underwriters, became effective under the
Act in such form; no other document with respect to such registration statement
or documents incorporated by reference therein has heretofore been filed or
transmitted for filing with the Commission and no other document incorporated by
reference in the prospectus contained therein has heretofore been filed with the
Reviewing Authority, except for any documents filed with the Commission or the
Reviewing Authority subsequent to the date of such effectiveness in the form
heretofore delivered to the Representative for delivery by them to each of the
other Underwriters; no stop order suspending the effectiveness of such
registration statement has been issued and, to the Company's knowledge, no
proceeding for that purpose has been initiated or threatened by the Commission;
the various parts of such registration statement, including all exhibits thereto
and the documents incorporated by reference in the prospectus contained in the
registration statement at the time such part of the registration statement
became effective but excluding the Form T-1 of the Trustee, each as amended at
the time such part of the registration statement became effective and including
any post effective amendment thereto, are hereinafter collectively called the
"REGISTRATION STATEMENT"; the prospectus relating to the Securities, in the form
in which it has most recently been filed, or transmitted for filing, with the
Commission on or prior to the Execution Time, being hereinafter called the "U.S.
BASIC PROSPECTUS"; with respect to the Securities, "U.S. FINAL PROSPECTUS" means
the U.S. Basic Prospectus as amended or supplemented prior to the Execution
Time, until such time as the first

                                       2
<PAGE>

prospectus supplement relating to the offering of the Securities is filed with
the Commission pursuant to General Instruction II.K., at which time "U.S. FINAL
PROSPECTUS" with respect to such Securities, shall mean the U.S. Basic
Prospectus including such supplement; and "CANADIAN FINAL PROSPECTUS" means the
Basic Prospectus as amended or supplemented prior to the Execution Time, until
such time as the first prospectus supplement relating to the offering of the
Securities is filed with the Reviewing Authority, at which time "CANADIAN FINAL
PROSPECTUS" shall mean the Basic Prospectus including such supplement; any
reference herein to any U.S. Basic Prospectus, Basic Prospectus, Preliminary
Final Prospectus, Canadian Final Prospectus or U.S. Final Prospectus shall be
deemed to refer to and include the documents incorporated by reference therein
as of the date of such U.S. Basic Prospectus, Basic Prospectus, Preliminary
Final Prospectus, Canadian Final Prospectus or U.S. Final Prospectus, as the
case may be; any reference to any amendment or supplement to any U.S. Basic
Prospectus, Basic Prospectus, Preliminary Final Prospectus, Canadian Final
Prospectus or U.S. Final Prospectus shall be deemed to refer to and include any
documents filed as of the date of such amendment or supplement under Alberta
Securities Law, or the Exchange Act, as the case may be, and incorporated by
reference in such amendment or supplement;

         (C) INCORPORATED DOCUMENTS. The Canadian Documents, when they were
filed with the Reviewing Authority and incorporated by reference into the
Canadian Final Prospectus, conformed in all material respects to the
requirements of Alberta Securities Law, the documents included or incorporated
by reference in the Registration Statement and the U.S. Final Prospectus, when
they became effective or were filed with the Commission, as the case may be,
conformed in all material respects to any applicable requirements of the
Exchange Act and the rules and regulations of the Commission thereunder and any
further documents so filed and incorporated by reference in the Canadian Final
Prospectus and the U.S. Final Prospectus or any amendment or supplement thereto,
when such documents are filed with the Reviewing Authority or the Commission,
will conform in all material respects to the requirements of Alberta Securities
Law, or the Exchange Act, as applicable;

         (D) DISCLOSURE CONFORMITY. On the Effective Date the Registration
Statement did, and on the date it was first filed and on the Closing Date, the
U.S. Final Prospectus did and will conform in all material respects with the Act
and the Trust Indenture Act and the rules and regulations of the Commission
under both the Act and the Trust Indenture Act; on the date each was first
filed, the Basic Prospectus did and the Canadian Final Prospectus will, and on
the Closing Date each will, conform in all material respects with the applicable
requirements of Alberta Securities Law and the rules and regulations of the
Reviewing Authority under Alberta Securities Law; the Registration Statement, as
of the Effective Date, and the Basic Prospectus as of its filing date, and in
each case at the Execution Time, did not and will not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; and the Canadian Final
Prospectus and the U.S. Final Prospectus, will not as of their filing dates and
as of the Closing Date, contain an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading; PROVIDED, HOWEVER, that this representation and warranty

                                       3
<PAGE>

shall not apply to any statements or omissions made in reliance upon and in
conformity with information furnished in writing to the Company by or on behalf
of any Underwriter through the Representative specifically for inclusion in the
Registration Statement, the Canadian Final Prospectus or the U.S. Final
Prospectus, or to the Form T-1 of the Trustee;

         (E) COMPANY GOOD STANDING. The Company has been duly incorporated and
is validly existing as a corporation under the laws of Canada with full
corporate power and authority to own or lease, as the case may be, and to
operate its properties and conduct its business as described in the Canadian
Final Prospectus and the U.S. Final Prospectus, and is duly qualified to
transact business and is in good standing in each jurisdiction in which the
conduct of its business or its ownership or leasing of property requires such
qualification, except to the extent that the failure to be so qualified or be in
good standing would not have a material adverse effect on the condition
(financial or otherwise), earnings, business or properties of the Company and
its subsidiaries, taken as a whole;

         (F) SUBSIDIARY GOOD STANDING. Each of the Company's Significant
Subsidiaries has been duly incorporated, is validly existing as a corporation in
good standing under the laws of the jurisdiction of its incorporation, has the
corporate power and authority to own its property and to conduct its business as
described in the Canadian Final Prospectus and the U.S. Final Prospectus (or as
presently conducted, if not so described therein) and is duly qualified to
transact business and is in good standing in each jurisdiction in which the
conduct of its business or its ownership or leasing of property requires such
qualification, except to the extent that the failure to be so qualified or be in
good standing would not have a material adverse effect on the Company and its
subsidiaries taken as a whole. Other than the Significant Subsidiaries, each of
the other subsidiaries of the Company did not have (x) as of the last day of the
Company's most recent fiscal year, total assets in excess of 10% of the
consolidated assets of the Company and its subsidiaries as at that date and (y)
for the fiscal year then ended, total revenues in excess of 10% of the
consolidated revenues of the Company and its subsidiaries for such period. In
making this determination, any subsidiary acquired after the last day of the
Company's most recent fiscal year shall be deemed to have been acquired as of
such date;

         (G) EXISTING INSTRUMENTS. There is no franchise, contract or other
document of a character required to be described in the Registration Statement,
the Canadian Final Prospectus or the U.S. Final Prospectus, or to be filed as an
exhibit thereto, which is not described or filed as required; and the statements
in the Canadian Final Prospectus or the U.S. Final Prospectus under the headings
"Certain Income Tax Information", "Description of Debt Securities" and
"Description of the Notes" insofar as such statements summarize legal matters,
agreements, documents or proceedings discussed therein, are accurate and fair
summaries of such legal matters, agreements, documents or proceedings;

         (H) AGREEMENT, SECURITIES AND INDENTURE AUTHORIZATION. The Company has
full corporate power and authority to execute, deliver and perform its
obligations under this Agreement and this Agreement has been duly authorized,
executed and delivered by the Company; the Securities have been duly authorized
and, when the Securities are issued and delivered pursuant to this Agreement,
such Securities will have

                                       4
<PAGE>

been duly executed, authenticated, issued and delivered and, upon payment for
the Securities by the Representative to the Company, will constitute valid and
legally binding obligations of the Company entitled to the benefits of the
Indenture; the Indenture, which was incorporated by reference as an exhibit to
the Registration Statement, has been duly authorized and duly qualified under
the Trust Indenture Act and constitutes a valid and legally binding instrument,
and enforceable against the Company in accordance with its terms, except as the
enforcement thereof may be limited by bankruptcy, insolvency, reorganization,
fraudulent conveyances or transfer, moratorium or similar laws affecting
creditors' rights generally and subject to general principles of equity
(regardless of whether enforceability is considered in a proceeding in equity or
at law) and to the provisions of the Currency Act (Canada) or to the usury
provisions of the Criminal Code (Canada); no registration, filing or recording
of the Indenture under the laws of Canada or any province thereof is necessary
in order to preserve or protect the validity or enforceability of the Indenture
or the Securities issued thereunder; and the Indenture conforms, and the
Securities will conform in all material respects to the descriptions thereof
contained in the Canadian Final Prospectus and the U.S. Final Prospectus with
respect to such Securities;

         (I) INVESTMENT COMPANY ACT. The Company is not and, after giving effect
to the offering and sale of the Securities and the application of the proceeds
as described in the Canadian Final Prospectus and the U.S. Final Prospectus
under the heading "Use of Proceeds," will not be an "investment company" as
defined in the Investment Company Act of 1940, as amended, and the rules and
regulations of the Commission promulgated thereunder;

         (J) GOVERNMENTAL AUTHORIZATION AND ABSENCE OF FURTHER REQUIREMENTS. No
Governmental Authorization is required in connection with the transactions
contemplated herein, except such as have been obtained under the Act, Alberta
Securities Law, and the Trust Indenture Act and such as may be required under
the blue sky laws of any jurisdiction in connection with the purchase and
distribution of the Securities by the Underwriters in the manner contemplated
herein and in the Canadian Final Prospectus and the U.S. Final Prospectus;
except as set forth in or contemplated in the Canadian Final Prospectus and the
U.S. Final Prospectus, the Company and its subsidiaries possess all licenses,
certificates, permits and other authorizations issued by the appropriate
foreign, federal, provincial, state, municipal or local regulatory authorities
necessary to conduct their respective businesses except where the failure to
possess such license, certificate, permit or other authorization would not,
individually or in the aggregate, have a material adverse effect on the
condition (financial or otherwise), earnings, business or properties of the
Company and its subsidiaries, taken as a whole, and neither the Company nor any
such subsidiary has received any notice of proceedings relating to the
revocation or modification of any such license, certificate, authorization or
permit which, singly or in the aggregate, if the subject of an unfavorable
decision, ruling or finding, would have a material adverse effect on the
condition (financial or otherwise), earnings, business or properties of the
Company and its subsidiaries, taken as a whole, whether or not arising from
transactions in the ordinary course of business;

         (K) MATERIAL CHANGES. Since the representative dates as of which
information is given in the Registration Statement, the Canadian Final
Prospectus and the

                                       5
<PAGE>

U.S. Final Prospectus, except as may otherwise be stated therein or contemplated
thereby, there has been no material adverse change, actual or to the knowledge
of the Company, pending, in the condition (financial or otherwise), earnings,
business or properties of the Company and its subsidiaries, taken as a whole,
whether or not arising in the ordinary course of business;

         (L) NO DEFAULT AND CONFLICT ABSENCE. Neither the issue and sale of the
Securities nor the consummation of any other of the transactions herein
contemplated will conflict with, result in a breach or violation or imposition
of any lien, charge or encumbrance upon any property or assets of the Company or
any of its Significant Subsidiaries pursuant to, (i) the charter or by-laws of
the Company or any of its Significant Subsidiaries, (ii) the terms of any
indenture, contract, lease, mortgage, deed of trust, note agreement, loan
agreement or other agreement, obligation, condition, covenant or instrument to
which the Company or any of its Significant Subsidiaries is a party or bound or
to which its or their property is subject, or (iii) any statute, law, rule,
regulation, judgment, order or decree applicable to the Company or any of its
Significant Subsidiaries of any court, regulatory body, administrative agency,
governmental body, arbitrator or other authority having jurisdiction over the
Company or any of its Significant Subsidiaries or any of its or their
properties, except, in the case of (ii) or (iii), such breaches, violations,
liens, charges or encumbrances as would not, individually or in the aggregate,
constitute a material adverse effect on the condition (financial or otherwise),
earnings, business or properties of the Company and its subsidiaries, taken as a
whole; except as set forth in or contemplated in the Canadian Final Prospectus
and the U.S. Final Prospectus, neither the Company nor any Significant
Subsidiary is in violation or default of (i) any provision of its charter or
bylaws or other constating documents, (ii) the terms of any indenture, contract,
lease, mortgage, deed of trust, note agreement, loan agreement or other
agreement, obligation, condition, covenant or instrument to which it is a party
or bound or to which its property is subject, or (iii) any statute, law, rule,
regulation, judgment, order or decree of any court, regulatory body,
administrative agency, governmental body, arbitrator or other authority having
jurisdiction over the Company or such Significant Subsidiary or any of its
properties, as applicable, except, in the case of (ii) or (iii) such violation
or default as would not, individually or in the aggregate, constitute a material
adverse effect on the condition (financial or otherwise), earnings, business or
properties of the Company and its subsidiaries, taken as a whole;

         (M) FINANCIAL STATEMENTS. The consolidated historical financial
statements of the Company included or incorporated by reference in the Canadian
Final Prospectus, the U.S. Final Prospectus and the Registration Statement
present fairly in all material respects the financial condition, results of
operations and cash flows of the Company as of the dates and for the periods
indicated, comply as to form with the applicable accounting requirements of the
Act and Alberta Securities Law and have been prepared in conformity with
Canadian generally accepted accounting principles and have been reconciled to
U.S. generally accepted accounting principles in accordance with Item 17 of Form
40-F under the Exchange Act, in each case applied on a consistent basis
throughout the periods involved (except as otherwise noted therein). Any
selected financial data set forth in the Canadian Final Prospectus, the U.S.
Final Prospectus and the Registration Statement fairly present, on the basis
stated under such caption in the Canadian Final Prospectus, the U.S. Final
Prospectus and the Registration Statement, the information included therein;

                                       6
<PAGE>

         (N) PROCEEDINGS ABSENCE. Except as set forth in or contemplated in the
Canadian Final Prospectus and the U.S. Final Prospectus, no action, suit or
proceeding by or before any court or Governmental Authority involving the
Company or any of its subsidiaries or its or their property is pending or, to
the best knowledge of the Company, threatened that (i) could reasonably be
expected to have a material adverse effect on the performance of this Agreement
or the consummation of any of the transactions contemplated hereby or (ii) could
reasonably be expected to have a material adverse effect on the condition
(financial or otherwise), earnings, business or properties of the Company and
its subsidiaries, taken as a whole, whether or not arising from transactions in
the ordinary course of business;

         (O) OWNERSHIP OF PROPERTY. Each of the Company and each of its
subsidiaries owns or leases all such properties as are necessary to the conduct
of its operations as presently conducted, except such as would not, individually
or in the aggregate, constitute a material adverse effect on the condition
(financial or otherwise), earnings, business or properties of the Company and
its subsidiaries, taken as a whole;

         (P) INDEPENDENT ACCOUNTANTS. KPMG LLP, who have certified certain
financial statements of the Company and its consolidated subsidiaries and
delivered their report with respect to the audited consolidated financial
statements included or incorporated by reference in the Canadian Final
Prospectus and the U.S. Final Prospectus, are independent chartered accountants
with respect to the Company within the meaning of Alberta Securities Law and the
Act and the applicable published rules and regulations thereunder;

         (Q) MARKET STABILIZATION. The Company has not taken, directly or
indirectly, any action designed to or that would constitute or that might
reasonably be expected to cause or result in, under Alberta Securities Law, or
the Exchange Act or otherwise, stabilization or manipulation of the price of any
security of the Company to facilitate the sale or resale of the Securities;

all permits, licenses or other approvals required of them under applicable
Environmental Laws to conduct their respective businesses and (iii) have not
received notice of any actual or potential liability for the investigation or
remediation of any disposal or release of hazardous or toxic substances or
wastes, pollutants or contaminants, except where such non-compliance with
Environmental Laws, failure to receive required permits, licenses or other
approvals, or liability would not, individually or in the aggregate, have a
material adverse effect on the condition (financial or otherwise), earnings,
business or properties of the Company and its subsidiaries, taken as a whole,
whether or not arising from transactions in the ordinary course of business.
Except as set forth in the Canadian Final Prospectus and the U.S. Final
Prospectus, neither the Company nor any of the subsidiaries has been named as a

<PAGE>

or the Basic Prospectus or U.S. Basic Prospectus (including the Canadian Final
Prospectus, the U.S. Final Prospectus or any Preliminary Final Prospectus)
unless the Company has furnished a copy to the Representative for their review
prior to filing and will not file any such proposed amendment or supplement to
which the Representative reasonably object unless filing is immediately required
by law without right of appeal. Subject to the foregoing sentence, the Company
will prepare the Canadian Final Prospectus and the U.S. Final Prospectus setting
forth the principal amount of Securities covered thereby, the terms not
otherwise specified in the Basic Prospectus and U.S. Basic Prospectus pursuant
to which the Securities are being issued, the names of the Underwriters
participating in the offering and the principal amount of Securities which each
severally has agreed to purchase, the names of the Underwriters acting as
co-managers in connection with the offering, the price at which the Securities
are to be purchased by the Underwriters from the Company, the initial public
offering price, the selling concession and reallowance, if any, in a form
approved by the Representative and shall file (i) such Canadian Final Prospectus
with the Reviewing Authority in accordance with the Shelf Procedures and (ii)
such U.S. Final Prospectus with the Commission pursuant to General Instruction
II.K. of Form F-9 not later than the Commission's close of business on the
business day following the date of the filing thereof with the Reviewing
Authority. The Company will promptly file all reports required to be filed by it
with the Reviewing Authority pursuant

                                       8

to Alberta Securities Law, and the Commission pursuant to Section 13(a), 13(c)
or 15(d) of the Exchange Act for so long as the delivery of a prospectus is
required in connection with the offering or sale of the Securities, and during
such same period will advise the Representative, promptly after it receives
notice thereof, of the time when any amendment to the Canadian Final Prospectus
has been filed or receipted, when any amendment to the Registration Statement
has been filed or becomes effective or any supplement to the Basic Prospectus or
U.S. Basic Prospectus or any amended Canadian Final Prospectus or U.S. Final
Prospectus has been filed with the Reviewing Authority or the Commission, of the
issuance by the Reviewing Authority or the Commission of any stop order or of
any order preventing or suspending the use of any prospectus relating to the
Securities, of the suspension of the qualification of such Securities for
offering or sale in any jurisdiction, of the initiation or threatening, to the
knowledge of the Company, of any proceeding for any such purpose, or of any
request by the Reviewing Authority or the Commission for the amending or
supplementing of the Registration Statement, the Canadian Final Prospectus or
the U.S. Final Prospectus or for additional information relating to the
Securities; and the Company will use its commercially reasonable best efforts to
prevent the issuance of any such stop order or any such order preventing or
suspending the use of any prospectus relating to the Securities or the
suspension of any such qualification and, in the event of the issuance of any
such stop order or of any such order preventing or suspending the use of any
prospectus relating to the Securities or suspending any such qualification, to
use its commercially reasonable best efforts to obtain the withdrawal of such
order as soon as possible;

         (b) Notwithstanding the provisions of paragraph (a) above, if, at any
time when a prospectus relating to the Securities is required to be delivered
under the Act, any event occurs as a result of which the Canadian Final
Prospectus or the U.S. Final Prospectus, each as then supplemented, would
include any untrue statement of a material fact or omit to state any material
fact necessary to make the statements therein in the light of the circumstances
under which they were made not misleading, or if it shall be necessary to amend
the Registration Statement or supplement the Canadian Final Prospectus or the
U.S. Final Prospectus to comply with Alberta Securities Law, the Act or the
Exchange Act, or the respective rules thereunder, the Company will promptly (1)
notify the Representative of such event, (2) prepare and file with the Reviewing
Authority and the Commission, an amendment or supplement which will correct such
statement or omission or effect such compliance and (3) supply any supplemented
Canadian Final Prospectus and U.S. Final Prospectus to the Representative in
such quantities as they may reasonably request;

         (c) As soon as practicable, the Company will make generally available
to its security holders an earnings statement or statements of the Company and
its subsidiaries which will satisfy the provisions of Section 11(a) of the Act
and Rule 158 under the Act;

         (d) The Company will furnish to the Representative and counsel for the
Underwriters, without charge, copies of the Registration Statement (including
exhibits thereto) and to the Representative for delivery to each other
Underwriter a copy of the Registration Statement (without exhibits thereto) and,
so long as delivery of a prospectus by an Underwriter or dealer may be required
by the Act, as many copies of each Preliminary Final Prospectus and U.S. Final
Prospectus and any supplement thereto as

                                       9
<PAGE>

the Representative may reasonably request. The Company will pay the expenses of
printing or other production of all documents relating to the offering;

         (e) The Company will arrange, if necessary, for the qualification of
the Securities for sale under the laws of such jurisdictions as the
Representative may designate upon consultation with the Company and will
maintain such qualifications in effect so long as required for the distribution
of the Securities and will pay any fee of the National Association of Securities
Dealers, Inc., in connection with its review of the offering; provided that in
no event shall the Company be obligated to qualify to do business in any
jurisdiction where it is not now so qualified or to take any action that would
subject it to service of process in suits, other than those arising out of the
offering or sale of the Securities, in any jurisdiction where it is not now so
subject;

         (f) The Company will not, without the prior written consent of the
Representative, offer, sell, contract to sell, pledge, or otherwise dispose of,
(or enter into any transaction which is designed to, or might reasonably be
expected to, result in the disposition (whether by actual disposition or
effective economic disposition due to cash settlement or otherwise) by the
Company or any affiliate of the Company or any person in privity with the
Company or any affiliate of the Company) directly or indirectly, including the

announce an intention to effect any such transaction within the U.S. marketplace

         (g) The Company will furnish to the Trustee reports and other
information in accordance with the requirements specified in Section 4.3 of the
Indenture;

of any Securities in the manner specified in the U.S. Final Prospectus and the
Canadian Final Prospectus under the caption "Use of Proceeds;"

         (i) In connection with each offering of Securities, the Company will
take such steps as it deems necessary to ascertain promptly whether (i) the
Canadian Final Prospectus prepared in connection with such offering was received
for filing by the Reviewing Authority and (ii) whether the U.S. Final Prospectus
prepared in connection with such offering and transmitted for filing pursuant to
General Instruction II.K. of Form F-9 was received for filing by the Commission,
and, in the event that any such prospectuses were not received for filing, it
will promptly file any such prospectus not then received for filing;

         (j) The Company agrees to pay the costs and expenses relating to the
following matters: (i) the preparation, printing or reproduction and filing with
the Commission of the Registration Statement (including financial statements and
exhibits thereto) and with the Review Authority of each Preliminary Final
Prospectus, the Canadian Final Prospectus and U.S. Final Prospectus, and each
amendment or supplement to any of them; (ii) the printing (or reproduction) and

copies of the Registration Statement, each Preliminary Final Prospectus, the
Canadian Final Prospectus and U.S. Final Prospectus, and all amendments or
supplements to any of them, as may, in each case, be reasonably requested for
use in connection with the offering and sale of the Securities; (iii) the

responsible for the fees and disbursements of more than one law firm (other than
local counsel) for all the Underwriters in connection with the transactions

otherwise, stabilization or manipulation of the price of any security of the
Company to facilitate the sale or resale of the Securities.

         5. CONDITIONS TO THE OBLIGATIONS OF THE UNDERWRITERS. The obligations

                                       12
<PAGE>

     supplemented prior to the Execution Time and the U.S. Final Prospectus, as
     amended or supplemented prior to the Execution Time, there has been no
     material adverse effect on the condition (financial or otherwise),
     earnings, business or properties of the Company and its subsidiaries, taken
     as a whole, whether or not arising from transactions in the ordinary course
     of business, except as set forth in or contemplated in the Canadian Final

         (v) the Company is in compliance with the covenants and conditions in

     incurrence of funded indebtedness;

         (g) At the Execution Time and the Closing Date, the Representative
shall have received from KPMG LLP a letter or letters dated such date or dates,
in form and substance satisfactory to the Representative, together with signed

included in accountants' "comfort letters" to underwriters with respect to the
financial statements and certain financial information contained in the

Prospectus;

         (h) Subsequent to the Execution Time or, if earlier, the dates as of
which information is given in the Registration Statement as amended or
supplemented prior to the Execution Time, and the Canadian Final Prospectus as
amended or supplemented prior to the Execution Time and the U.S. Final
Prospectus as amended or supplemented prior to the Execution Time, there shall

the ordinary course of business, except as set forth in or contemplated in the
Canadian Final Prospectus, as amended or supplemented prior to the Execution
Time and the U.S. Final Prospectus, as amended or supplemented prior to the
Execution Time, the effect of which, in any case referred to in clause (i) or
(ii) above, is, in the sole judgment of the Representative, so material and
adverse as to make it impractical or inadvisable to proceed with the offering or
delivery of the Securities as contemplated by the Registration Statement and the
Canadian Final Prospectus and the U.S. Final Prospectus;

         (i) Subsequent to the Execution Time, there shall not have been any

Agreement shall not be in all material respects reasonably satisfactory in form

at the office of the Company, Attention: Corporate Finance Law Department, 450 -
1st Street S.W., Calgary, Alberta, T2P 5H1 on the Closing Date or such other
place as the Representative shall so instruct.

         6. REIMBURSEMENT OF UNDERWRITERS' EXPENSES. If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 5 hereof is not satisfied,
or because of any refusal, inability or failure on the part of the Company to
perform any agreement herein or comply with any provision hereof other than by
reason of a default by any of the Underwriters, the Company will reimburse the
Underwriters severally through the Representative on demand for all reasonable
out-of-pocket expenses (including reasonable fees and disbursements of counsel)
that shall have been incurred by them in connection with the proposed purchase
and sale of the Securities.

         7. INDEMNIFICATION AND CONTRIBUTION.

         (a) The Company agrees to indemnify and hold harmless each Underwriter,
the directors, officers, employees and agents of each Underwriter and each
person, if any, who controls any Underwriter within the meaning of the Act
against any and all losses, claims, damages or liabilities, joint or several, to
which they or any of them may become subject under the Act, the Exchange Act or
other Federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement as
originally filed, the Basic Prospectus, any Preliminary Final Prospectus, the
Canadian Final Prospectus and the U.S. Final Prospectus, or in all cases any
amendment thereof or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
agrees to reimburse each such indemnified party, as incurred, for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the Company will not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon any such untrue
statement or alleged untrue statement or omission or alleged omission made
therein in reliance upon and in conformity with written information furnished to
the Company by or on behalf of any Underwriter through the Representative

                                       14
<PAGE>

specifically for inclusion therein; provided, however, that with respect to any
untrue statement or alleged untrue statement in or omission or alleged omission
from the Registration Statement, the Basic Prospectus, any Preliminary Final
Prospectus, the Canadian Final Prospectus or the U.S. Final Prospectus, the
indemnity provisions contained in this subsection (a) shall not inure to the
benefit of any Underwriter from whom the person asserting any such loss, claim,
damage or liability purchased the Securities concerned to the extent that a
prospectus relating to the Securities was required to be delivered by such
underwriter under the Act in connection with such purchase and any such loss,
claim, damage or liability of such Underwriter results from the fact that there
was not sent or given to such person, at or prior to the written confirmation of
the sale of such debt securities to such person, a copy of the Basic Prospectus,
any Preliminary Final Prospectus, the Canadian Final Prospectus or the U.S.
Final Prospectus if the Company had previously furnished copies thereof which
corrected such untrue statement, alleged untrue statement, omission or alleged
omission to such Underwriter. This indemnity agreement will be in addition to
any liability which the Company may otherwise have.

         (b) Each Underwriter severally and not jointly agrees to indemnify and
hold harmless the Company, each of its directors, its officers, and each person
who controls the Company within the meaning of either the Act or the Exchange
Act, to the same extent as the foregoing indemnity from the Company to each
Underwriter, but only with reference to written information relating to such
Underwriter furnished to the Company by or on behalf of such Underwriter through
the Representative specifically for inclusion in the documents referred to in
the foregoing indemnity. This indemnity agreement will be in addition to any
liability which any Underwriter may otherwise have. The Company acknowledges
that the statements set forth, in the last paragraph of the cover page regarding
delivery of the Securities and, under the heading "Underwriting", (i) the names
listed in the table included in the second paragraph of the text, (ii) the
fourth paragraph of text concerning concessions, (iii) the sixth, seventh and
eighth paragraphs of text concerning price stabilization, short positions and
penalty bids, (iv) the third sentence in the ninth paragraph of text concerning
market making by the Underwriters and (v) the twelfth paragraph of text
concerning electronic prospectuses, in any Preliminary Final Prospectus,
Canadian Final Prospectus and U.S. Final Prospectus constitute the only
information furnished in writing by or on behalf of the several Underwriters for
inclusion in any Preliminary Final Prospectus, the U.S. Final Prospectus or
Canadian Final Prospectus.

         (c) Promptly after receipt by an indemnified party under this Section 8
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof;
but the failure so to notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party other than the indemnification obligation provided in paragraph (a) or (b)
above. The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the

                                       15
<PAGE>

indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); PROVIDED, HOWEVER, that such counsel shall be
reasonably satisfactory to the indemnified party. Notwithstanding the
indemnifying party's election to appoint counsel to represent the indemnified
party in an action, the indemnified party shall have the right to employ
separate counsel (including local counsel), and the indemnifying party shall
bear the reasonable fees, costs and expenses of such separate counsel if (i) the
use of counsel chosen by the indemnifying party to represent the indemnified
party would present such counsel with a conflict of interest, (ii) the actual or
potential defendants in, or targets of, any such action include both the
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be legal defenses available to it
and/or other indemnified parties which are different from or additional to those
available to the indemnifying party, (iii) the indemnifying party shall not have
employed counsel reasonably satisfactory to the indemnified party to represent
the indemnified party within a reasonable time after notice of the institution
of such action or (iv) the indemnifying party shall authorize the indemnified
party to employ separate counsel at the expense of the indemnifying party. An
indemnifying party will not, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding.

         (d) In the event that the indemnity provided in paragraph (a) or (b) of
this Section 7 is unavailable to or insufficient to hold harmless an indemnified
party for any reason, the Company and the Underwriters severally agree to
contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "LOSSES") to which the Company and one or more of
the Underwriters may be subject in such proportion as is appropriate to reflect
the relative benefits received by the Company on the one hand and by the
Underwriters on the other from the offering of the Securities; PROVIDED,
HOWEVER, that in no case shall any Underwriter (except as may be provided in any
agreement among underwriters relating to the offering of the Securities) be
responsible for any amount in excess of the total price at which the Securities
underwritten and distributed to the public by such Underwriter was offered to
the public. If the allocation provided by the immediately preceding sentence is
unavailable for any reason, the Company and the Underwriters severally shall
contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Company on the one hand and
of the Underwriters on the other in connection with the statements or omissions
which resulted in such Losses as well as any other relevant equitable
considerations. Benefits received by the Company shall be deemed to be equal to
the total net proceeds from the offering (before deducting expenses) received by
it, and benefits received by the Underwriters shall be deemed to be equal to the
total underwriting discounts and commissions, in each case as set forth on the
cover page of the Canadian Final Prospectus and the U.S. Final Prospectus.
Relative fault shall be determined by reference to, among other things, whether
any untrue or any alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact

                                       16
<PAGE>

relates to information provided by the Company on the one hand or the
Underwriters on the other, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The Company and the Underwriters agree that it
would not be just and equitable if contribution were determined by pro rata
allocation or any other method of allocation which does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. For purposes of
this Section 8, each person who controls an Underwriter within the meaning of
the Act and each director, officer, employee and agent of an Underwriter shall
have the same rights to contribution as such Underwriter, and each person who
controls the Company within the meaning of the Act, each officer of the Company
and each director of the Company shall have the same rights to contribution as
the Company, subject in each case to the applicable terms and conditions of this
paragraph (d).

         8. DEFAULT BY AN UNDERWRITER. If any one or more Underwriters shall
fail to purchase and pay for any of the Securities agreed to be purchased by
such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, then the Representative shall have the right, within 24 hours
thereafter, to make arrangements for one or more of the non-defaulting
Underwriters, or any other underwriters, to purchase all, but not less than all
of the unsold Securities in such amounts as may be agreed upon and upon the
terms herein set forth; if, however, the Representative shall not have completed
such arrangements within such 24-hour period, then the remaining Underwriters
shall be obligated severally to take up and pay for (in the respective
proportions which the principal amount of Securities set forth opposite their
names in Schedule II hereto bears to the aggregate principal amount of
Securities set forth opposite the names of all the remaining Underwriters) the
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase; provided, however, that in the event that the aggregate principal
amount of Securities which the defaulting Underwriter or Underwriters agreed but
failed to purchase shall exceed 10% of the aggregate principal amount of
Securities set forth in Schedule II hereto, the remaining Underwriters shall
have the right to purchase all, but shall not be under any obligation to
purchase any, of the Securities, and if such nondefaulting Underwriters do not
purchase all the Securities, this Agreement will terminate without liability to
any nondefaulting Underwriter or the Company. In the event of a default by any
Underwriter as set forth in this Section 8, the Closing Date shall be postponed
for such period, not exceeding seven Business Days, as the Representative shall
determine in order that the required changes in the Registration Statement, the
Canadian Final Prospectus and the U.S. Final Prospectus or in any other
documents or arrangements may be effected. Nothing contained in this Agreement
shall relieve any defaulting Underwriter of its liability, if any, to the
Company and any nondefaulting Underwriter for damages occasioned by its default
hereunder.

         9. TERMINATION. This Agreement shall be subject to termination in the
absolute discretion of the Representative, by notice given to the Company prior
to delivery of and payment for the Securities, if at any time prior to such
time, (i) trading in securities generally on the New York Stock Exchange or the
Toronto Stock Exchange or the Nasdaq National Market shall have been suspended
or limited or minimum prices

                                       17

shall have been established on any of such Exchanges, (ii) a banking moratorium
shall have been declared either by authorities in the United States, Canada or
New York state, (iii) a change or development involving a prospective change in
Canadian taxation affecting the Securities or the transfer thereof or the
imposition of exchange controls by the United States or Canada, or (iv) there
shall have occurred any outbreak or escalation of hostilities, except as
existing with similar severity on the date hereof involving Canada or the United
States, declaration by the United States or Canada of a national emergency or
war, or other calamity or crisis, except as existing with similar severity on
the date hereof the effect of which on financial markets is such as to make it,
in the sole judgment of the Representative, impractical or inadvisable to
proceed with the offering or delivery of the Securities as contemplated by the
Canadian Final Prospectus and the U.S. Final Prospectus.

         10. REPRESENTATIONS AND INDEMNITIES TO SURVIVE. The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Underwriters set forth in or made pursuant to

the officers, directors, employees, agents or controlling persons referred to in
Section 7 hereof, and will survive delivery of and payment for the Securities.
The provisions of Sections 6 and 7 hereof shall survive the termination or
cancellation of this Agreement.

         12. SUCCESSORS. This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the
officers, directors, employees, agents and controlling persons referred to in
Section 7 hereof, and no other person will have any right or obligation
hereunder.

         13. SUBMISSION TO JURISDICTION; AGENT FOR SERVICE; WAIVER OF
IMMUNITIES. The Company irrevocably (i) agrees that any legal suit, action or
proceeding against the Company brought by any Underwriter or by any person who
controls any Underwriter arising out of or based upon this Agreement or the
transactions contemplated thereby may be instituted in any New York Court, (ii)
waives, to the fullest extent it may effectively do so, any objection which it
may now or hereafter have to the laying of venue of any such proceeding and
(iii) submits to the non-exclusive jurisdiction of such courts in any such suit,
action or proceeding. The Company has appointed TransCanada Power Marketing Ltd.
as its authorized agent (the "AUTHORIZED AGENT") upon whom process may be served
in any such action arising out of or based on this Agreement or the transactions
contemplated thereby which may be instituted in any New York Court by any
Underwriter or by any person who controls any Underwriter, expressly consents to
the jurisdiction of any such court in respect of any such action, and waives any
other requirements of or objections to personal jurisdiction with respect
thereto. Such appointment shall be irrevocable. The Company represents and
warrants that the

                                       18
<PAGE>

Authorized Agent has agreed to act as such agent for service of process and
agrees to take any and all action, including the filing of any and all documents
and instruments, that may be necessary to continue such appointment in full
force and effect as aforesaid. Service of process upon the Authorized Agent and
written notice of such service to the Company shall be deemed, in every respect,
effective service of process upon the Company.

     To the extent that the Company has or hereafter may acquire any immunity
from jurisdiction of any court or from any legal process (whether through
service of notice, attachment prior to judgment, attachment in aid of execution,
execution or otherwise) with respect to itself or its property, it hereby
irrevocably waives such immunity in respect of its obligations under the
above-referenced documents, to the extent permitted by law.

     The provisions of this Section 13 shall survive any termination of this
Agreement, in whole or in part.

         14. JUDGMENT CURRENCY. The obligation of the Company in respect of any
sum due to any Underwriter shall, notwithstanding any judgment in a currency
other than United States dollars, not be discharged until the first Business Day
following receipt by such Underwriter of any sum adjudged to be so due in such
other currency, on which (and only to the extent that) such Underwriter may in
accordance with normal banking procedures purchase United States dollars with
such other currency; if the United States dollars so purchased are less than the
sum originally due (as converted into U.S. dollars at the rate of exchange
announced by the Bank of Canada on the day on which the final judgment is
entered) to such Underwriter hereunder, the Company agrees, as a separate
obligation and notwithstanding any such judgment, to indemnify such Underwriter
against such loss. If the United States dollars so purchased are greater than
the sum originally due to such Underwriter hereunder, such Underwriter agrees to
pay to the Company an amount equal to the excess of the dollars so purchased
over the sum originally due to such Underwriter hereunder.

                       OPINION OF MAYER, BROWN ROWE & MAW,

                      UNITED STATES COUNSEL TO THE COMPANY

         (i) TransCanada PipeLine USA Ltd. and TransCanada Energy USA Inc.
(individually a "U.S. Subsidiary" and collectively the "U.S. Subsidiaries") are
corporations in good standing under the laws of the jurisdiction in which they
are chartered or organized.

         (ii) Assuming the compliance of the Canadian Final Prospectus,
including the documents incorporated by reference therein, with the requirements
of the securities laws and regulations of the Province of Alberta and other
requirements of Canadian law, the Registration Statement and the U.S. Final
Prospectus (other than the financial statements, including schedules, and other
financial and statistical information contained therein or omitted therefrom,
and the Form T-1, as to which such counsel need express no opinion) appeared on
their face to be appropriately responsive as to form in all material respects
with the applicable requirements of the Act and the rules and regulations
thereunder; the Form F-X, as of its date, appears on its face to be
appropriately responsive in all material respects to the requirements of the
Securities Act.

         (iii) No consent, approval, authorization or order of, or filing,
registration or qualification with, any Governmental Authority, which has not
been obtained, taken or made (other than as required by any state securities
laws, as to which such counsel expresses no opinion) is required on the part of
the Company under any Applicable Law for the issuance or sale of the Securities
or the performance by the Company of its obligations under this Agreement and
the Indenture. For purposes of this opinion, the term "Governmental Authority"
means any executive, legislative, judicial, administrative or regulatory body of
the State of New York or the United States of America. For purposes of this
opinion, the term "Applicable Law" means those laws, rules and regulations of
the United States of America and the State of New York, in each case which in
our experience are normally applicable to the transactions of the type
contemplated by this Agreement.

         (iv) Assuming that the Indenture has been duly authorized by the
Company, the Indenture (to the extent execution and delivery are governed by the
laws of New York) has been duly executed and delivered by the Company and
constitutes a valid and legally binding obligation of the Company, enforceable
against the Company in accordance with its terms, except that the enforceability
of the Indenture may be subject to bankruptcy, insolvency, reorganization,
fraudulent conveyance or transfer, moratorium or similar laws affecting
creditors' rights generally and subject to general principles of equity
(regardless of whether enforceability is considered in a proceeding in equity or
at law), and the Indenture conforms in all material respects to the description
thereof contained in the U.S. Final Prospectus under the caption "Description of
Debt Securities" and under the caption "Description of the Notes." The Indenture
has been duly qualified under the Trust Indenture Act.

<PAGE>

         (v) Assuming that the Securities have been duly authorized by the
Company, when duly executed and authenticated in accordance with the provisions
of the Indenture and delivered by the Company against payment as provided in
this Agreement, the Securities will constitute valid and legally binding
obligations of the Company entitled to the benefits of the Indenture and will be
enforceable against the Company in accordance with their terms, except that the
enforceability of the Securities may be subject to bankruptcy, insolvency,
reorganization, fraudulent conveyance or transfer, moratorium or similar laws
affecting creditors' rights generally and subject to general principles of
equity (regardless of whether enforceability is considered in a proceeding in
equity or at law). The Securities, when issued and delivered, will conform in
all material respects to the description contained in the U.S. Final Prospectus,
under the caption "Description of the Notes" and "Description of Debt
Securities" and are in a form contemplated in the Indenture.

         (vi) Assuming that this Agreement has been duly authorized by the
Company, this Agreement (to the extent execution and delivery are governed by
the laws of New York) has been duly executed and delivered by the Company.

         (vii) The Company is not and, after giving effect to the offering and
the sale of the Securities and the application of their proceeds as described in
the U.S. Final Prospectus under the heading "Use of Proceeds," will not be
required to be registered as an investment company under the Investment Company
Act of 1940, as amended, and the rules and regulations of the Commission
promulgated thereunder.

         (viii) The statements in the U.S. Final Prospectus under the caption
"Certain Income Tax Considerations - United States Federal Income Taxation
Considerations," to the extent that they constitute summaries of United States
federal statutes, rules and regulations, or portions thereof, are accurate in
all material respects.

         (ix) Neither the execution and delivery of this Agreement and the
Indenture, nor the issue and sale of the Securities, nor the consummation of any
other of the transactions herein contemplated nor the fulfillment of the terms
hereof will conflict with, result in a breach or violation of or imposition of
any lien, charge or encumbrance upon any property or assets of the Company or
its subsidiaries pursuant to (i) the terms of such material agreements as are
set out in Schedule A hereto or (ii) any United States federal or New York State
statute, law, rule, regulation known to such counsel to be applicable to the
Offering, excluding the Company's and any subsidiary's specially regulated
activities (as to which such counsel need express no opinion) or, to the
knowledge of such counsel, any judgment, order or decree applicable to the
Company or its subsidiaries of any United States federal or New York State
court, regulatory body, administrative agency, governmental body, arbitrator or
other authority having jurisdiction over the Company or its subsidiaries or any
of its or their properties in the United States, except, in the case of (i) or
(ii), such conflicts, breaches, violations, liens, charges and encumbrances
that, individually or in the aggregate, would not reasonably be

                                      I-2
<PAGE>

         expected to have a material adverse effect on the condition (financial
         or otherwise), earnings, business or properties of the Company and its
         subsidiaries, taken as a whole.

         Such counsel will state that they have been advised by the Commission
that the Registration Statement has become effective under the Act. Such counsel
will further state that, to the knowledge of such counsel, no stop order
suspending the effectiveness of the Registration Statement has been issued, no
proceedings for that purpose have been instituted or threatened.

         Such counsel will state that they have participated in the preparation
of the Registration Statement and the U.S. Final Prospectus and in conferences
with officers and other representatives of the Company, representatives of the
independent chartered accountants for the Company, the Underwriters and
representatives of the Underwriters at which the contents of the Registration
Statement, the U.S. Final Prospectus and related matters were discussed. Given
the limitations inherent in the independent verification of factual matters and
the character of determinations involved in the registration process, such
counsel may state that they have not verified, and are not passing upon and do
not assume responsibility for, the accuracy, completeness or fairness of the
statements contained in either of them (other than as explicitly stated in
paragraph (viii) above), and have made no independent check or verification
thereof. Subject to the foregoing and based upon such participation (and relying
as to materiality as to factual matters to the extent such counsel deems
reasonable on officers, employees and other representatives of the Company), no
facts have come to our attention to lead us to believe that (a) the Registration
Statement, at its effective date and on the date of this Agreement, contained an
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein not misleading
or (b) the U.S. Final Prospectus, as of the date the U.S. Final Prospectus was
issued and as of the Closing Date, included or includes an untrue statement of a
material fact or omitted or omits to state a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading. In each case, counsel need not express any belief as
to (i) financial statements, financial statement schedules and other financial
and statistical information or data included or incorporated by reference in or
omitted from the Registration Statement and the U.S. Final Prospectus, (ii) the
Form T-1 or (iii) discussions of the regulation of the Company's business under
the federal and provincial laws of Canada in documents filed with the Reviewing
Authority or filed with the SEC and incorporated by reference in the
Registration Statement and the U.S. Final Prospectus. In connection with the
foregoing, such counsel may state that it is the understanding of the addresses
of such opinion that such counsel does not act as United States regulatory
counsel of the Company and does not hold itself out as an expert on the
regulation of the generation, transportation, distribution or delivery of
natural gas, oil, electricity or other specially regulated commodities or
services, including pipelines, transmission lines, storage facilities and
related facilities and equipment, or the import or export of such commodities or
services.

         In rendering such opinion, such counsel may (A) exclude from such
opinions the effect or applicability of any United States or Canadian federal,
state and local laws, rules or regulations relating to the regulation of the
generation, transportation, distribution or delivery of natural gas, oil,
electricity or other specially regulated commodities or services, including
pipelines,

                                      I-3
<PAGE>

transmission lines, storage facilities and related facilities and equipment, or
the import or export of such commodities or services, (B) rely as to matters
involving the application of laws of any jurisdiction other than the State of
New York or the Federal laws of the United States, to the extent they deem
proper and specified in such opinion, upon the opinion of other counsel of good
standing whom they believe to be reliable and who are satisfactory to counsel
for the Underwriters and (C) as to matters of fact, to the extent they deem
proper, on certificates of responsible officers of the Company and public
officials.

                        OPINION OF MCCARTHY TETRAULT LLP
                         CANADIAN COUNSEL TO THE COMPANY

         (i) The Company has been duly incorporated, is validly existing as a
corporation under the laws of Canada and has the corporate power and authority
to own or lease, as the case may be, and to operate its property and conduct its
business as described in the Canadian Final Prospectus;

         (ii) each of NOVA Gas Transmission Ltd., 701671 Alberta Ltd. and
TransCanada Energy Ltd. (individually a "Canadian Subsidiary" and collectively
the "Canadian Subsidiaries") has been duly incorporated, is validly existing as
a corporation under the jurisdiction of its incorporation and has the corporate
power and authority to own or lease, as the case may be, and to operate its
property and to conduct its business as described in the Canadian Final
Prospectus;

         (iii) the Indenture has been duly authorized, executed and, to the
extent delivery is a matter governed by the laws of the Province of Alberta or
the federal laws of Canada, delivered by the Company; and no registration,
filing or recording of the Indenture under the laws of the Province of Alberta
and the federal laws of Canada applicable therein (the "Applicable Law") is
necessary in order to preserve or protect the validity or enforceability of the
Indenture or the debt securities issued thereunder, including the Securities;

         (iv) the Securities have been duly authorized by the Company and,
assuming that the Securities have been duly authenticated by the Trustee in the
manner described in the Indenture and under New York law, the Securities have
been, to the extent issuance, execution and delivery are matters governed by the
laws of the Province of Alberta or the federal laws of Canada applicable
therein, issued, executed and delivered by the Company; the Securities conform
in all material respects to the description thereof in the Canadian Final
Prospectus;

         (v) the Agreement has been duly authorized, executed and, to the extent
delivery is governed by Applicable Law, delivered by the Company;

         (vi) the execution and delivery by the Company of, and the performance
by the Company of its obligations under the Agreement, the Indenture and the
Securities will not contravene any provisions of (i) the articles of
incorporation or by-laws of the Company, (ii) Applicable Law applicable to the
Offering, excluding the Company's and any subsidiary's specially regulated
activities (as to which such counsel need express no opinion), (iii) any
indenture, mortgage, deed of trust, loan, credit agreement, note or any other
agreement listed in Schedule A hereto on the part of the Company or the Canadian
Subsidiaries, or, (iv) to the best of such counsel's knowledge, any judgment,
order or decree of any governmental body, agency or court in Canada having
jurisdiction over the Company or the Canadian Subsidiaries except in the case of
(ii), (iii) or (iv), such conflicts, breaches, violations, liens, charges and
encumbrances that, individually, or in the aggregate, would not reasonably be
expected to have a material adverse effect on the condition (financial or
otherwise), earnings, business or properties of the Company and its
subsidiaries, taken as a whole;

                                      II-1
<PAGE>

         (vii) no consent, approval or authorization or order of or
registration, qualification, recording or filing with any governmental body or
agency in Canada is required on the part of the Company pursuant to the laws of
the Province of Alberta or the federal laws of Canada applicable therein or the
related rules, regulations and policy statements thereunder for the performance
by the Company of its obligations under the Agreement, the Indenture or the
Securities except such as may be required under the securities laws, rules and
regulations applicable in the Province of Alberta as interpreted and applied by
the Reviewing Authority or such as has been obtained under the Canada Business
Corporations Act;

         (viii) the statements in the Canadian Final Prospectus under the
captions "Certain Canadian Income Tax Considerations", "Description of Debt
Securities" and "Description of Notes" insofar as such statements constitute
summaries of the Canadian legal matters, agreements, documents or proceedings
referred to therein, fairly summarize the matters referred to therein, subject
to specific limitations and qualifications stated or referred to therein and
applicable thereto;

         (ix) each document incorporated by reference in the Canadian Final
Prospectus (other than the financial statements, including schedules, and other
financial or statistical data included therein or omitted therefrom, as to which
such counsel need express no opinion), when such document was filed with the
Reviewing Authority, appeared on their face to be appropriately responsive as to
form in all material respects with the requirements of the securities laws,
rules and regulations of the Province of Alberta as interpreted and applied by
the Reviewing Authority;

         (x) a receipt has been obtained in respect of the Basic Prospectus from
the Reviewing Authority, the Canadian Final Prospectus has been filed with the
Reviewing Authority in the manner and within the time period required by the
Shelf Procedures and all necessary documents have been filed, all necessary
proceedings have been taken and all necessary authorizations, approvals,
permits, consents and orders have been obtained under the securities laws of the
Province of Alberta, and no other authorization, approval, permit, consent,
licence or order of any government, government instrumentality or court under
the laws of the Province of Alberta or the laws of Canada applicable therein are
required, for the valid authorization, issuance, sale and delivery of the
Securities through the Underwriters in connection with a public offering thereof
in the United States, and, to the best knowledge of such counsel, no order
having the effect of ceasing or suspending the distribution of the Securities
has been issued by the Reviewing Authority and no proceedings for that purpose
have been instituted or are pending or contemplated;

         (xi) the Basic Prospectus, at the time a final receipt was issued
therefor, and the Canadian Final Prospectus, as of the date of its filing with
the Reviewing Authority (other than the financial statements, financial
schedules and other financial or statistical data included in the foregoing
documents, as to which such counsel need express no opinion) complied or comply
as to form in all material respects with the requirements, including the Shelf
Procedures, of the securities laws, rules and regulations of the Province of
Alberta as interpreted and applied by the Reviewing Authority;

                                      II-2
<PAGE>

         (xii) such counsel does not know of any contracts or documents of a
character required to be described, referred to or filed in or with the Canadian
Prospectus that are not described, referred to or filed as required; there are
no reports or other information that in accordance with the requirements of the
Reviewing Authority must be made publicly available in connection with the
offering of the Securities that have not been made publicly available as
required;

         (xiii) no withholding tax imposed under the federal laws of Canada or
the laws of the Province of Alberta will be payable in respect of any commission
or fee to be paid by the Company pursuant to this Agreement to an Underwriter
that is not resident in Canada for purposes of the INCOME TAX ACT (Canada),
provided that such Underwriter deals at arm's length with the Company (as such
term is understood for purposes of the INCOME TAX ACT (Canada)), any such
commission or fee is payable in respect of services rendered by such Underwriter
wholly outside of Canada that are performed in the ordinary course of business
carried on by the Underwriter that includes the performance of such services for
a fee and any such amount is reasonable in the circumstances;

         (xiv) any final and conclusive judgment IN PERSONAM against the Company
in respect of the Agreement, the Indenture or the Securities or any agreement or
instrument entered into in connection therewith by a court of the State of New
York or of the United States located in the State of New York (a "New York
Court"), which is not impeachable as void or voidable under the internal laws of
the State of New York, for a fixed sum would be recognized and enforced by a
court of competent jurisdiction in the Province of Alberta, if (i) the court
rendering judgment had jurisdiction over the Company, as recognized by the
courts of the Province of Alberta; (ii) such judgment was not obtained by fraud
or in a manner contrary to natural justice and the enforcement thereof would not
be inconsistent with public policy, as such term is understood under the laws of
the Province of Alberta; (iii) the enforcement of such judgment does not
constitute, directly or indirectly, the enforcement of foreign revenue or penal
laws; and (iv) there has been compliance with the LIMITATIONS ACT (Alberta);
provided, however, that interest payable on a judgment debt may be limited by
the INTEREST ACT (Canada) and the JUDGMENT INTEREST ACT (Alberta), that a
monetary judgment of a court of the Province of Alberta may only be awarded in
Canadian currency and that the enforceability thereof may be limited by
applicable bankruptcy, insolvency or other laws of general application limiting
the enforcement of creditors' rights generally. We have no reason to believe
that the enforcement of any such judgment in respect of the Agreement, the
Indenture or the Securities would be inconsistent with public policy as such
term is understood under the laws of the Province of Alberta and the federal
laws of Canada applicable therein;

         (xv) in the event that any of the Agreement, the Indenture or the
Securities is sought to be enforced in any action or proceedings in the Province
of Alberta in accordance with the laws applicable thereto as chosen by the
parties, namely the laws of the State of New York, the courts of the Province of
Alberta would recognize such choice of laws, provided that such choice of laws
was not made with a view to avoiding the consequences of the laws of any other
jurisdiction and provided that such choice is not contrary to public policy as
such term is understood under the laws of the Province of Alberta and the
federal laws of Canada applicable therein. We have no reason to believe that
such choice of laws was made for the purpose of

                                      II-3
<PAGE>

avoiding the consequences of the laws of any other jurisdiction or that such
choice of laws would be inconsistent with public policy as such term is
understood under the laws of the Province of Alberta and the federal laws of
Canada applicable therein;

         (xvi) in the event that any of the Agreement, the Indenture or the
Securities is sought to be enforced in any action or proceeding in the Province
of Alberta in accordance with the laws applicable thereto as chosen by the
parties, namely the laws of the State of New York, the courts of the Province of
Alberta would, subject to paragraph (xv) above, apply the laws of the State of
New York, upon appropriate evidence as to such laws being adduced, to all issues
that, under the conflict of laws rules of the laws of the Province of Alberta
and the federal laws of Canada applicable therein, are to be determined in
accordance with the proper or governing law of the respective contract or
obligation, provided that none of the provisions of the applicable document or
the laws of the State of New York are contrary to public policy as such term is
understood under the laws of the Province of Alberta and the federal laws of
Canada applicable therein; and further provided, however, that interest payable
on a judgment debt may be limited by the INTEREST ACT (Canada) and the JUDGMENT
INTEREST ACT (Alberta) and that a monetary judgment of a court of the Province
of Alberta may only be awarded in Canadian currency. A court in the Province of
Alberta has, however, an inherent power to decline to hear such an action or
proceeding if it is contrary to public policy, as such term is understood under
the laws of the Province of Alberta and the federal laws of Canada applicable
therein for it to do so, or if it is not the proper forum to hear such action,
or if concurrent proceedings are being brought elsewhere. We have no reason to
believe that any of the provisions of the Agreement, the Indenture or the
Securities are contrary to public policy as such term is understood under the
laws of the Province of Alberta and the federal laws of Canada applicable
therein or that it would be inconsistent with public policy as such term is
understood under the laws of the Province of Alberta and the federal laws of
Canada applicable therein for a court of the Province of Alberta to hear an
action or proceeding to enforce the Agreement, the Indenture or the Securities;

         (xvii) the submission by the Company to the non-exclusive jurisdiction
of the courts of the State of New York or the courts of the United States of
America located in The City of New York, contained in the Agreement, the
Indenture and the Securities, would be recognized and given effect by the courts
of the Province of Alberta as a valid submission to the jurisdiction of such
courts, provided that the applicable provisions, if any, of the Agreement, the
Indenture and the Securities, respectively, respecting service of process on the
Company are duly complied with; and

         (xviii) the courts in the Province of Alberta would recognize the
appointment by the Company of TransCanada Power Marketing Ltd. as its agent for
service of process in the United States of America under the Agreement, the
Indenture and the Securities.

Such counsel may state that in connection with the preparation by the Company of
the Canadian Final Prospectus, such counsel attended conferences with certain of
the officers of, and the independent public accountants for, the Company, at
which the Canadian Final Prospectus was discussed. Such counsel may state
further that they participated in the preparation of the Company's most recently
filed Annual Information Form, required under Canadian securities

                                      II-4
<PAGE>

law and had discussions with certain officers of the Company at which the
contents of the Canadian Final Prospectus was discussed to a limited extent.
Given the limitations inherent in the independent verification of factual
matters and the character of determinations involved in the qualification
process, such counsel may state that, except for the statements contained in
paragraph (viii) above, they have not verified and are not passing upon and do
not assume any responsibility for the accuracy, completeness or genuineness or
fairness of the statements contained in or omitted from the Canadian Final
Prospectus and have made no independent verification thereof.

Subject to the foregoing and on the basis of the information such counsel gained
in the performance of the services referred to above and a review of the
Canadian Final Prospectus and the documents incorporated by reference therein,
including information obtained from officers and other representatives of the
Company, such counsel shall state that no facts have come to such counsel's
attention that cause such counsel to believe that the Basic Prospectus at the
time a final receipt was issued therefor on the date of this Agreement, and on
the date of filing of any amendment or supplement to the Basic Prospectus with
the Reviewing Authority prior to the date of such opinion, contained or contains
any untrue statement of a material fact or omitted or omits to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading. Also, subject to the foregoing, such counsel shall state that no
facts have come to such counsel's attention in the course of the proceedings
described above that cause them to believe that the Canadian Final Prospectus as
of the date of its filing with the Reviewing Authority and the date and time of
delivery of such opinion contained or contains, as the case may be, any untrue
statement of a material fact or omitted or omits, as the case may be, to state a
material fact necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. In each case, counsel
need not express any belief as to (i) financial statements, financial statement
schedules and other financial and statistical information or data included or
incorporated by reference in or omitted from the Basic Prospectus and the
Canadian Final Prospectus or (ii) discussions of the regulation of the Company's
business under the federal and provincial laws of Canada or the United States in
documents filed with the Reviewing Authority or filed with the SEC and
incorporated by reference in the Basic Prospectus or Canadian Final Prospectus.
In connection with the foregoing, such counsel may state that it is the
understanding of the addressees of such opinion that such counsel does not act
as Canadian or United States regulatory counsel to the Company on the regulation
of the generation, transportation, distribution or delivery of natural gas, oil,
electricity or other specially regulated commodities or services, including
pipelines, transmission lines, storage facilities and related facilities and
equipment, or the import or export of such commodities of services.

In giving the opinions described above, such counsel may (A) exclude from such
opinions the effect or applicability of any United States or Canadian federal,
provincial, territorial, state and local laws, rules or regulations relating to
the regulation of the generation, transportation, distribution or delivery of
natural gas, oil, electricity or other specially regulated commodities or
services, including pipelines, transmission lines, storage facilities and
related facilities and equipment, or the import or export of such commodities or
services, (B) state that the opinions above are limited to the laws of the
Province of Alberta and the federal laws of Canada therein

                                      II-5
<PAGE>

(C) rely solely upon the opinion of Mayer, Brown Rowe & Maw to be delivered
pursuant to Section 5(b) of this Agreement with respect to all matters relating
to the laws of the United States and the State of New York and (D) as to matters
of fact, to the extent they deem proper, on certificates of responsible officers
of the Company and public officials. In addition, in connection with the belief
expressed above, such counsel may assume that the terms "material fact" and
"misleading" have the same interpretation under United States law as the same
have under the Alberta Securities Act.

                   OPINION OF IN-HOUSE COUNSEL TO THE COMPANY

         (i) no consent, approval or authorization or order or registration,
qualification, recording or filing with the Federal Energy Regulatory
Commission, the National Energy Board, or any other federal, state, provincial
or local governmental body or agency in the United States or Canada responsible
for the regulation of the generation, transportation or delivery of natural gas,
oil, electricity or other specially regulated commodities or services, including
pipelines, transmission lines, storage facilities and related facilities and
equipment, or the import or export of such commodities or services (excluding
any federal, state, provincial or local governmental body or agency in the
United States or Canada having jurisdiction over offers and sales of the Notes
under the securities laws of the United States or the applicable provinces and
territories of Canada or the securities or Blue Sky laws of the various states,
as to which such counsel need not express any opinion) is required for the
performance by the Company of its obligations under this Agreement, the
Indenture or the Securities;

         (ii) the statements in any relevant document filed with the Reviewing
Authority or filed with the SEC and specifically incorporated by reference into
the U.S. Final Prospectus and the Canadian Final Prospectus and, in each case,
insofar as such statements constitute summaries of legal matters, documents,
proceedings, applications or approvals relating to the regulation in the United
States or Canada of the generation, transportation, distribution or delivery of
natural gas, oil, electricity or other specially regulated commodities or
services, including pipelines, transmission lines, storage facilities and
related facilities and equipment, or the import or export of such commodities or
services, referred to therein, fairly summarize in all material respects the
matters referred to therein, as of the date of the above-listed documents; and

         (iii) on the basis of the information gained in the performance of such
counsel's duties to the Company and on review of the Registration Statement, the
U.S. Final Prospectus, the Canadian Final Prospectus and the documents
incorporated by reference therein, including information obtained from officers
and other representatives of the Company, no facts have come to such counsel's
attention that cause such counsel to believe that the Registration Statement
(except for financial statements and schedules and other financial data included
therein or omitted therefrom, as to which such counsel need not make any
statement), at the time the Registration Statement became effective, on the date
of this Agreement, and on the effective date of any post-effective amendment to
the Registration Statement which became effective prior to the date of such
opinion, contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading
or that the U.S. Final Prospectus and Canadian Final Prospectus (except for
financial statements and schedules and other financial data included therein or
omitted therefrom, as to which such counsel need not make any statement), as of
their respective issue dates and the date and time of delivery of such opinion,
included or includes an untrue statement of a material fact or omitted or omits
to state a material fact necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading.

Such counsel shall confirm that its requisite state and provincial legal
