                  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 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 Noteholders entitled thereto, subject,
however, to the last paragraph of Section 2.7C of the Administration Agreement.
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.

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


                SECTION 2.9  Release of Collateral. Subject to Section 11.1 and
                             ---------------------

accompanied by an Officers' Certificate of the Issuer, an Opinion of Counsel and
Independent Certificates in accordance with TIA ss.ss. 314(c) and 314(d)(1) or
an Opinion of Counsel in lieu of such Independent Certificates to the effect
that the TIA does not require any such Independent Certificates.


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

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

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

                                       10

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

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

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

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

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

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

                                       11

<PAGE>

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

                                   ---------

                  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, subject to Section 8.2(c), 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

                                       12

<PAGE>

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

                  SECTION 3.3 Money for Payments To Be Held in Trust. As
                              --------------------------------------
provided in Section 8.2(a) and (b), all payments of amounts due and payable with
respect to any Notes that are to be made from amounts distributed from the
Collection Account or any other Trust Account pursuant to Section 8.2(c) 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 Seller; and the Noteholder thereof shall thereafter, as an
unsecured general creditor, look only to the Issuer for payment thereof (but
only to the extent of the amounts so paid to the Issuer), and all liability of
the Indenture Trustee or such Paying Agent with respect to such trust money
shall thereupon cease; provided, however, that the Indenture Trustee or such
                       --------  -------
Paying Agent, before being required to make any such repayment, shall at the
expense and direction of the Issuer cause to be published once, in a newspaper
published in the English language, customarily published on each Business Day
and of general circulation in The City of New York, notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication, any unclaimed balance of
such money then

                                       14

<PAGE>

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 business 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

                  (iii)  enforce any of the Collateral; or

                  (iv)   preserve and defend title to the Indenture Trust Estate

                    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
2002, 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 Adminis-

                                       17

<PAGE>

trator, 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. As soon as a
Successor Servicer or a Successor Administrator is appointed, the Issuer shall
notify the Indenture Trustee and each Rating Agency of such appointment,
specifying in such notice the name and address of such Successor Servicer or
such Successor Administrator.

         (g) Without derogating from the absolute nature of the assignment
granted to the Indenture Trustee under this Indenture or the rights of the
Indenture Trustee hereunder, the Issuer agrees that it will not, without the
prior written consent of the Indenture Trustee or the Noteholders of at least a
majority in Outstanding Amount of the Notes, amend, modify, waive, supplement,
terminate or surrender, or agree to any amendment, modification, supplement,
termination, waiver or surrender of, the terms of any Collateral or the Basic
Documents, except to the extent otherwise provided in the Basic Documents, or
waive timely performance or observance by the Servicer, the Administrator, the
Seller, the Student Loan Marketing Association, the Issuer or the Eligible
Lender Trustee under the Basic Documents; provided, however, that no such
                                          --------  -------
amendment shall (i) increase or reduce in any manner the amount of, or
accelerate or delay the timing of, distributions that are required to be made
for the benefit of the Noteholders, or (ii) reduce the aforesaid percentage of
the Notes which are required to consent to any such amendment, without the
consent of the Noteholders of all the Outstanding Notes. If any such amendment,
modification, supplement or waiver shall

                                       19

<PAGE>



be so consented to by the Indenture Trustee or such Noteholders, the Issuer
shall give written notice thereof to each Rating Agency and agrees, promptly
following a request by the Indenture Trustee to do so, to execute and deliver,
in its own name and at its own expense, such agreements, instruments, consents
and other documents as the Indenture Trustee may deem necessary or appropriate
in the circumstances.

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

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

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

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

                  (iv)  enter into any amendment to the Swap Agreement requested
by the Swap Counterparty to cure any ambiguity in, or to correct or supplement
any provision of the Swap Agreement, except where the Issuer has received the
consent of the Indenture Trustee so long as the Issuer has determined, and the
Indenture Trustee

                                       20

<PAGE>



has agreed in writing at the written direction of the Issuer, that the amendment
will not materially adversely affect the interests of the Noteholders and
provided that the Indenture Trustee has provided reasonable notice to the Rating
Agencies of such amendment.

              SECTION 3.9   Annual Statement as to Compliance. The Issuer will
                            ---------------------------------
deliver to the Indenture Trustee and each Rating Agency, within 120 days after
the end of each fiscal year of the Issuer (commencing with the fiscal year
ending December 31, 2002), an Officers' Certificate of the Issuer stating that:

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

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

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

                  (c)      the Issuer has delivered to the Indenture Trustee an

to Section 11.2, each stating that all conditions precedent herein provided for
relating to the satisfaction and discharge of this Indenture have been complied
with.

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

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

                  SECTION 4.4 Auction of Trust Student Loans. Any Trust Student
                              ------------------------------
Loans remaining in the Trust as of the end of the Collection Period immediately
preceding the earliest Distribution Date on which the Pool Balance is equal to
10% or less of the initial Pool Balance three business days prior to such
Distribution Date (the "Trust Auction Date") shall be offered for sale by the
Indenture Trustee unless the Seller 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 Seller 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 Seller in accordance with this Section 4.4. The Indenture
Trustee shall provide written notice to the Seller of any such offer for sale at
least 5 business days in advance of the Trust Auction Date. The Indenture
Trustee shall permit the Seller or any of its Affiliates 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

                                       27

<PAGE>

such bid does not exceed the fair market value of the Trust Student Loans as of
the Trust Auction Date. If at least two bids are received, the Indenture Trustee
shall solicit and resolicit new bids from all participating bidders until only
one bid remains or the remaining bidders decline to resubmit bids. The Indenture
Trustee shall accept the highest of such remaining bids if it is equal to or in
excess of both the Minimum Purchase Amount and the fair market value of such
Trust Student Loans as of the end of the Collection Period immediately preceding
the Trust Auction Date. If at least two bids are not received or the highest bid
after the resolicitation process is completed is not equal to or in excess of
the higher of the Minimum Purchase Amount and the fair market value of the Trust
Student Loans, the Indenture Trustee shall not consummate such sale. The
Indenture Trustee may consult, and, at the direction of the Seller, 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 Seller'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 to the appointment or taking possession by a receiver, liquidator,
assignee, custodian, trustee, sequestrator or similar official of the Issuer or
for any substantial part of the Indenture Trust Estate, or the making by the
Issuer of any general assignment for the benefit of creditors, or the failure by
the Issuer generally to pay its debts as such debts become due, or the taking of
action by the Issuer in furtherance of any of the foregoing.

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

                                       29

<PAGE>

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 the last paragraph of Section 2.7C of the
Administration Agreement and to Section 5.4 of this Indenture.

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

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

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

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

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

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

                  SECTION 5.3 Collection of Indebtedness and Suits for
                              ----------------------------------------
Enforcement by Indenture Trustee. The Issuer covenants that if (i) default is
--------------------------------
made in the payment of any interest on any Note when the same becomes due and
payable, and such default

                                       30

<PAGE>

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

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

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

         (c) In case there shall be pending, relative to the Issuer or any other
obligor upon the Notes or any Person having or claiming an ownership interest in
the Indenture Trust Estate, Proceedings under Title 11 of the United States Code
or any other applicable Federal or state bankruptcy, insolvency or other similar
law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Issuer or its property or such other obligor or Person,
or in case of any other, comparable judicial Proceedings relative to the Issuer
or other obligor upon the Notes, or to the creditors or property of the Issuer
or such other obligor, the Indenture

Trustee, irrespective of whether the principal of any Notes shall then be due
and payable, as therein expressed or by declaration or otherwise and
irrespective of whether the Indenture Trustee shall have made any demand
pursuant to the provisions of this Section, shall be entitled and empowered, by
intervention in such proceedings or otherwise:

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

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

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

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

                                       32

<PAGE>

incurred, and all advances made, by the Indenture Trustee and each predecessor
Indenture Trustee except as a result of negligence or bad faith.

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

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

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

             SECTION 5.4 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;

                                       33

<PAGE>

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

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

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

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

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

                                       34

<PAGE>

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.

         (b) If the Indenture Trustee collects any money or property pursuant to
this Article V, it shall pay out the money or property 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 Class A Noteholders for amounts due and unpaid on the
Class A Notes for interest, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Class A Notes for such interest;

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

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

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

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

             EIGHTH:  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.

                  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 Seller, the Student Loan Marketing Association, 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

                                       40

<PAGE>

default on the part of the Seller, the Student Loan Marketing Association, the
Administrator or the Servicer thereunder and the institution of legal or
administrative actions or proceedings to compel or secure performance by the
Seller, the Student Loan Marketing Association, 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 Seller, the Student Loan
Marketing Association, 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 Seller, the
Student Loan Marketing Association, 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

                                       41

<PAGE>

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

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

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

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

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

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

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

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

     (f)  No provision of this Indenture shall require the Indenture Trustee to
expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder or in the exercise of any of its
rights or powers, if it shall have reasonable grounds to believe that repayments
of such funds or adequate

                                       42

<PAGE>

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

                                       43

<PAGE>

powers; provided, however, that the Indenture Trustee's conduct does not
        --------  -------
constitute willful misconduct, negligence or bad faith.

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

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

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

                  SECTION 6.5 Notice of Defaults; Seller Insolvency. (a) 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(a), in
no event shall the Indenture Trustee be deemed to have knowledge of a Default or
an Event of Default.

                                       44

<PAGE>

         (b) If the Indenture Trustee receives notice from the Eligible Lender
Trustee of the occurrence of an Insolvency Event with respect to the Seller
pursuant to Section 9.2 of the Trust Agreement, the Indenture Trustee shall give
prompt written notice to the Noteholders of the occurrence of such event and of
the effect of such event under such Section 9.2. Upon termination of the Trust
pursuant to such Section 9.2, the Indenture Trustee shall, if so directed by the
Eligible Lender Trustee, sell the Trust Estate (other than the Trust Accounts)
in a commercially reasonable manner and on commercially reasonable terms. The
proceeds of any such sale shall be treated as collections under the
Administration Agreement.

                  SECTION 6.6 Reports by Indenture Trustee to Noteholders. The
                              -------------------------------------------
Indenture Trustee shall deliver to each Noteholder (and to each Person who was a
Noteholder at any time during the applicable calendar year) such information as
may be required to enable such holder to prepare its Federal and state income
tax returns. Within 60 days after each December 31 beginning with the December
31 following the date of this Indenture, the Indenture Trustee shall mail to
each Noteholder a brief report as of such December 31 that complies with TIA ss.
313(a) if required by said section. The Indenture Trustee shall also comply with
TIA ss. 313(b). A copy of each such report required pursuant to TIA ss. 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 Seller to pay to the Indenture Trustee reasonable compensation for its
services in accordance with a separate agreement between the Seller and the
Indenture Trustee and shall cause the Seller 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

                                       45

<PAGE>

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

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

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

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

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

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

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

                                       46

<PAGE>

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

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

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

                                       47

<PAGE>

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

                  SECTION 6.10 Appointment of Co-Trustee or Separate Trustee.
                               ---------------------------------------------
(a) Notwithstanding any other provisions of this Indenture, at any time, for the
purpose of meeting any legal requirement of any jurisdiction in which any part
of the Indenture Trust Estate may at the time be located, the Indenture Trustee
shall have the power and may execute and deliver all instruments to appoint one
or more Persons to act as a co-trustee or co-trustees, or separate trustee or
separate trustees, of all or any part of the Indenture Trust Estate, and to vest
in such Person or Persons, in such capacity and for the benefit of the
Noteholders, such title to the Indenture Trust Estate, or any part hereof, and,
subject to the other provisions of this Section, such powers, duties,
obligations, rights and trusts as the Indenture Trustee may consider necessary
or desirable. No such appointment shall relieve the Indenture Trustee of its
obligations hereunder. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
6.11 and no notice to Noteholders of the appointment of any co-trustee or
separate trustee shall be required under Section 6.8 hereof.

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

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

resignation of or remove any separate trustee or co-trustee.

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

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.

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

          (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

by this Indenture,

                                       59

<PAGE>

the Indenture Trustee shall be entitled to receive, and subject to Sections 6.1
and 6.2, shall be fully protected in relying upon, an Opinion of Counsel stating
that the execution of such supplemental indenture is authorized or permitted by
this Indenture. The Indenture Trustee may, but shall not be obligated to, enter
into any such supplemental indenture that affects the Indenture Trustee's own
rights, duties, liabilities or immunities under this Indenture or otherwise.

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

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

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

          SECTION 10.1 Redemption. The Indenture Trustee shall, upon receipt of

Section 9.2 of the Trust Agreement, that portion of the amounts on deposit in
the Trust Accounts to be distributed to the Noteholders shall be paid to the
Noteholders up to the Outstanding Amount of the Notes and all accrued and unpaid
interest thereon (but only to the extent provided by Sections 2.7(d) and
8.2(c)). 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
                       -------------------------

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 were 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).

<PAGE>

          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.

                                  -------------

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

          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;

or investigation upon which the statements or opinions contained in such
certificate or opinion are based;

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

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

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

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

                                       63

<PAGE>

of the Issuer certifying or stating the opinion of each person signing such
certificate as to the fair value (within 90 days of such release) of the
property or securities proposed to be released and stating that in the opinion
of such person the proposed release will not impair the security under this
Indenture in contravention of the provisions hereof.

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

          (v) Notwithstanding Section 2.9 or any other provision of this
Section, the Issuer may, without compliance with the requirements of the other
provisions of this Section, (A) collect, liquidate, sell or otherwise dispose of
Trust Student Loans as and to the extent permitted or required by the Basic
Documents, (B) make cash payments out of the Trust Accounts as and to the extent
permitted or required by the Basic Documents and (C) convey to the Seller, 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
July 25, 2002, 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

                                      64

<PAGE>

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 Seller, the Issuer or the Administrator, stating that the
information with respect to such factual matters is in the possession of the
Servicer, the Seller, the Issuer or the Administrator, unless such counsel
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to such matters are erroneous.

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

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

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

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

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

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

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

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

                                       66

<PAGE>

     (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 2002-2, in
care of Chase Manhattan Bank USA, National Association, Christiana Center/OPS4,
500 Stanton Christiana Road, Newark, Delaware 19713, Attention: Corporate Trust
Department; with copies to The Chase Manhattan Bank, 450 West 33rd Street 15th
Fl., New York, New York 10001, Attention: Structured Finance Services; 11600
Sallie Mae Drive, Reston, VA 20193, Attention: Director, Corporate Finance
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 writing, personally
delivered or mailed by certified mail, return receipt requested, to (i) in the
case of Moody's, at the following address: Moody's, ABS Monitoring Department,
99 Church Street, New York, New York 10007, (ii) in the case of Standard &
Poor's, at the following address: Standard & Poor's, 55 Water Street, New York,
New York 10041-0003, Attention: Asset Backed Surveillance Department, 32/nd/
Floor, and (iii) in the case of Fitch, at the following address: One State
Street Plaza, New York, New York 10004, Attention Municipal Structured Finance
Group; or as to each of the foregoing, at such other address as shall be
designated by written notice to the other parties.

          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

                                       67

<PAGE>

or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Noteholders shall be filed with the Indenture Trustee but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such a waiver.

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

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

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

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

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

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

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

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

          SECTION 11.11 Benefits of Indenture. Nothing in this Indenture or in
                        ---------------------
the Notes, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, and the Noteholders, and any other party
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 (S)5-1401 of the New York General
Obligations Law), and the obligations, rights and remedies of the parties
hereunder shall be determined in accordance with such laws.

          SECTION 11.14 Counterparts. This Indenture may be executed in any
                        ------------
number of counterparts, each of which so executed shall be deemed to be an

                                       69

<PAGE>

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

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

          SECTION 11.16 Trust Obligations. No recourse may be taken, directly or
                        -----------------
indirectly, with respect to the obligations of the Issuer, the Seller, the
Administrator, the Servicer, the Eligible Lender Trustee or the Indenture
Trustee on the Notes or under this Indenture or any certificate or other writing
delivered in connection herewith or therewith, against (i) the Indenture Trustee
or the Eligible Lender Trustee in its individual capacity, (ii) any owner of a
beneficial interest in the Issuer or (iii) any partner, owner, beneficiary,
agent, officer, director or employee of the Indenture Trustee or the Eligible
Lender Trustee in its individual capacity, any holder or owner of a beneficial
interest in the Issuer, the Eligible Lender Trustee or the Indenture Trustee or
of any successor or assign thereof in its individual capacity, except as any
such Person may have expressly agreed (it being understood that the Indenture
Trustee and the Eligible Lender Trustee have no such obligations in their
individual capacity) and except that any such partner, owner or beneficiary

any Person other than the Indenture Trustee.

          SECTION 11.18 Inspection. The Issuer agrees that, on reasonable prior

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.

                                [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") and Floating Rate Class B
Student Loan-Backed Notes (the "Class B Notes" and, together with the Class A-1
Notes and Class A-2 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 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 25th day of each January, April, July and October or, if any such date
is not a Business Day, the next succeeding Business Day, commencing [initial
Distribution Date].

              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 [or such

                                       80

<PAGE>

other designated maturity or formula, as necessary, for the initial Accrual
Period] LIBOR as determined on the second Business Day before the beginning of
that Accrual Period plus [specified percentage points]%.

                  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

                                       81

<PAGE>

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 Seller or the Issuer, or join in any
institution against the Seller or the Issuer of, any bankruptcy, reorganization,
arrangement, insolvency, receivership or liquidation proceedings or other
proceedings under any United States

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

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

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

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

                  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.

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

                                [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") and the Issuer's Floating Rate
Class B Student Loan-Backed Notes (the "Class B Notes" and, together with the
Class A-1 Notes and the Class A-2 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 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 25th day of each January, April, July and October or, if any such date
is not a Business Day, the next succeeding Business Day, commencing [initial
Distribution Date].

                  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 [or such

                                       90

<PAGE>

other designated maturity or formula, as necessary, for the initial Accrual
Period] LIBOR as determined on the second Business Day before the beginning of
that Accrual Period plus [specified percentage points]%.

                  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

                                       91

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

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 Seller or the Issuer, or join in any
institution against the Seller or the Issuer of, any bankruptcy, reorganization,
arrangement, insolvency, receivership or liquidation proceedings or other
proceedings under any United States

                                       92

<PAGE>

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

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

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

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

                  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.

                                [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") and the Issuer's Floating Rate
Class A-2 Student Loan-Backed Notes (the "Class A-2 Notes" and, together with
the Class A-1 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 and Class A-2 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 25th day of each January, April, July and October or, if any such date
is not a Business Day, the next succeeding Business Day, commencing [initial
Distribution Date].

                  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 [or such other

                                       100

<PAGE>

designated maturity or formula, as necessary, for the initial Accrual Period]
LIBOR as determined on the second business day before the beginning of that
Accrual Period plus [specified percentage points]%.

                  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

                                       101

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 Seller or the Issuer, or join in any
institution against the Seller or the Issuer of, any bankruptcy, reorganization,
arrangement, insolvency,

                                       102

<PAGE>

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

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

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

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

                  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.
