         THIS INDENTURE OF TRUST, dated as of January 1, 2003 (this
"Indenture"), is by and between NELNET STUDENT LOAN TRUST 2003-1 (the "Issuer"),
a statutory trust duly organized and existing under the laws of the State of
Delaware (the "State"), and ZIONS FIRST NATIONAL BANK, a national banking
association duly organized and operating under the laws of the United States of
America (together with its successors, the "Trustee"), as trustee hereunder and
eligible lender trustee under the Eligible Lender Trust Agreement (all
capitalized terms used in these preambles, recitals and granting clauses shall
have the same meanings assigned thereto in Article I hereof);

                              W I T N E S S E T H :

         WHEREAS, the Issuer represents that it is duly created as a statutory
trust under the laws of the State and that by proper action has duly authorized
the execution and delivery of this Indenture, which Indenture provides for the
payment of student loan asset-backed notes (the "Notes") and the payments to any
Counterparty (as defined herein); and

         WHEREAS, this Indenture is subject to the provisions of the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act" or "TIA"), that are
deemed to be incorporated into this Indenture and shall, to the extent
applicable, be governed by such provisions; and

         WHEREAS, the Trustee has agreed to accept the trusts herein created
upon the terms herein set forth; and

         WHEREAS, it is hereby agreed between the parties hereto, the Registered
Owners of the Notes (the Registered Owners evidencing their consent by their
acceptance of the Notes) and any Counterparty (the Counterparty evidencing its
consent by its execution and delivery of a Derivative Product (as defined
herein)) that in the performance of any of the agreements of the Issuer herein
contained, any obligation it may thereby incur for the payment of money shall
not be general debt on its part, but shall be secured by and payable solely from

                         NOTE DETAILS AND FORM OF NOTES

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

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

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

         SECTION 2.02. EXECUTION, AUTHENTICATION AND DELIVERY OF NOTES. The
Notes shall be executed in the name and on behalf of the Issuer by the manual or
facsimile signature of an Authorized Representative. Any Note may be signed

principal amount of Notes outstanding at any time may not exceed such amount
except as provided in Section 2.04 hereof.

shall be issuable as registered Notes in the minimum denomination of $1,000 and
in integral multiples of $1,000 in excess thereof.

                                       21

<PAGE>

         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 in Section
2.05 hereof.

         SECTION 2.03. REGISTRATION, TRANSFER AND EXCHANGE OF NOTES; PERSONS
TREATED AS REGISTERED OWNERS. The Issuer shall cause books for the registration
and for the transfer of the Notes as provided in this Indenture to be kept by
the Trustee which is hereby appointed the transfer agent of the Issuer for the
Notes. Notwithstanding such appointment and with the prior written consent of
the Issuer, the Trustee is hereby authorized to make any arrangements with other
institutions which it deems necessary or desirable in order that such
institutions may perform the duties of transfer agent for the Notes. Upon
surrender for transfer of any Note at the Principal Office of the Trustee, duly
endorsed for transfer or accompanied by an assignment duly executed by the
Registered Owner or his attorney duly authorized in writing, the Issuer shall
execute and the Trustee shall authenticate and deliver in the name of the
transferee or transferees a new fully registered Note or Notes of the same
interest rate and for a like series, subseries, if any, and aggregate principal
amount of the same maturity.

         Notes may be exchanged at the Principal Office of the Trustee for a
like aggregate principal amount of fully registered Notes of the same series,
subseries, if any, interest rate and maturity in authorized denominations. The
Issuer shall execute and the Trustee shall authenticate and deliver Notes which
the Registered Owner making the exchange is entitled to receive, bearing numbers
not contemporaneously outstanding. The execution by the Issuer of any fully
registered Note of any authorized denomination shall constitute full and due
authorization of such denomination and the Trustee shall thereby be authorized
to authenticate and deliver such fully registered Note.

         As to any Note, the person in whose name the same shall be registered
shall be deemed and regarded as the absolute owner thereof for all purposes, and
payment of either principal or interest on any fully registered Note shall be
made only to or upon the written order of the Registered Owner thereof or his
legal representative but such registration may be changed as hereinabove
provided. All such payments shall be valid and effectual to satisfy and
discharge the liability upon such Note to the extent of the sum or sums paid.

         Each Registered Owner and each transferee of a Note shall be deemed to
represent and warrant that either (a) it is not acquiring the Note directly or
indirectly for, or on behalf of, an ERISA plan or any entity whose underlying
assets are deemed to be plan assets of such ERISA plan; or (b) (i) the
acquisition and holding of the Notes will not result in a nonexempt prohibited
transaction under Section 406 of ERISA or Section 4975 of the Code or similar
law and (ii) if the Notes are subsequently deemed to be "plan assets" pursuant
to the regulations set forth at 29 C.F.R. Section 2510.3-101, it will promptly
dispose of the Notes.

         The Trustee shall require the payment by any Registered Owner
requesting exchange or transfer of any tax or other governmental charge required
to be paid with respect to such exchange or transfer. The applicant for any such
transfer or exchange may be required to pay all taxes and governmental charges
in connection with such transfer or exchange, other than exchanges pursuant to
Section 2.07 hereof.

                                       22

         SECTION 2.04. LOST, STOLEN, DESTROYED AND MUTILATED NOTES. Upon receipt
by the Trustee of evidence satisfactory to it of the ownership of and the loss,
theft, destruction or mutilation of any Note and, in the case of a lost, stolen
or destroyed Note, of indemnity satisfactory to it, and upon surrender and
cancellation of the Note, if mutilated, (a) the Issuer shall execute, and the
Trustee shall authenticate and deliver, a replacement Note of the same interest
rate, maturity and denomination in lieu of such lost, stolen, destroyed or
mutilated Note or (b) if such lost, stolen, destroyed or mutilated Note shall
have matured within 15 days be due and payable, in lieu of executing and
delivering a new Note as aforesaid, the Issuer may pay such Note. Any such new
Note shall bear a number not contemporaneously outstanding. The applicant for
any such new Note may be required to pay all taxes and governmental charges and
all expenses and charges of the Issuer and of the Trustee in connection with the
issuance of such Note. All Notes shall be held and owned upon the express
condition that, to the extent permitted by law, the foregoing conditions are
exclusive with respect to the replacement and payment of mutilated, destroyed,
lost or stolen Notes, negotiable instruments or other securities.

         SECTION 2.05. TRUSTEE'S AUTHENTICATION CERTIFICATE. The Trustee's
authentication certificate upon any Notes shall be substantially in the form
attached to the Notes. No Note shall be secured hereby or entitled to the
benefit hereof, or shall be valid or obligatory for any purpose, unless a
certificate of authentication, substantially in such form, has been duly
executed by the Trustee; and such certificate of the Trustee upon any Note shall
be conclusive evidence and the only competent evidence that such Note has been
authenticated and delivered hereunder. The Trustee's certificate of
authentication shall be deemed to have been duly executed by it if manually
signed by an authorized officer or signatory of the Trustee, but it shall not be
necessary that the same person sign the certificate of authentication on all of
the Notes issued hereunder.

         SECTION 2.06. CANCELLATION AND DESTRUCTION OF NOTES BY THE TRUSTEE.
Whenever any Outstanding Notes shall be delivered to the Trustee for the
cancellation thereof pursuant to this Indenture, upon payment of the principal
amount and interest represented thereby, or for replacement pursuant to Section
2.03 hereof, such Notes shall be promptly cancelled and, within a reasonable
time, cremated or otherwise destroyed by the Trustee and counterparts of a
certificate of destruction evidencing such cremation or other destruction shall
be furnished by the Trustee to the Issuer.

         SECTION 2.07. TEMPORARY NOTES. Pending the preparation of definitive
Notes, the Issuer may execute and the Trustee shall authenticate and deliver
temporary Notes. Temporary Notes shall be issuable as fully registered Notes
without coupons, of any denomination, and substantially in the form of the
definitive Notes but with such omissions, insertions and variations as may be
appropriate for temporary Notes, all as may be determined by the Issuer. Every
temporary Note shall be executed by the Issuer and be authenticated by the
Trustee upon the same conditions and in substantially the same manner, and with
like effect, as the definitive Notes. As promptly as practicable the Issuer
shall execute and shall furnish definitive Notes and thereupon temporary Notes
may be surrendered in exchange therefor without charge at the principal office
of the Trustee, and the Trustee shall authenticate and deliver in exchange for
such temporary Notes a like aggregate principal amount of definitive Notes.
Until so exchanged the temporary Notes shall be entitled to the same benefits
under this Indenture as definitive Notes.

                                       23

<PAGE>

         SECTION 2.08. ISSUANCE OF NOTES. The Issuer shall have the authority,
upon complying with the provisions of this Section, to issue and deliver the
Notes which shall be secured by the Trust Estate. In addition, the Issuer may
enter into any Derivative Products it deems necessary or desirable with respect
to any or all of the Notes.

         SECTION 2.09. DEFINITIVE NOTES. If (a) the Administrator advises the
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; (b) the Administrator at its option advises the
Trustee in writing that it elects to terminate the book-entry system through the
Clearing Agency; or (c) after the occurrence of an Event of Default, or a
default by the Servicer or the Administrator under the Servicing Agreement or
the Administration Agreement, respectively, Noteholders representing beneficial
interests aggregating at least a majority of the Outstanding Amount of the Notes
advise the Clearing Agency (which shall then notify the Trustee) in writing that
the continuation of a book-entry system through the Clearing Agency is no longer
in the best interests of the Noteholders, then the Trustee shall cause the
Clearing Agency to notify all Noteholders, through the Clearing Agency, of the
occurrence of any such event and of the availability of definitive Notes to
Noteholders requesting the same. Upon surrender to the Trustee of the
typewritten Notes representing the book-entry Notes by the Clearing Agency,
accompanied by registration instructions, the Issuer shall execute and the
Trustee shall authenticate the definitive Notes in accordance with the
instructions of the Clearing Agency. None of the Issuer, the Note Registrar or
the 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 Trustee shall recognize
the holders of the definitive Notes as Registered Owners.

         SECTION 2.10. PAYMENT OF PRINCIPAL AND INTEREST.

                  (a)      The Notes shall accrue interest as provided in the
         forms of Notes set forth in Exhibit B, and such interest shall be
         payable on each Distribution Date as specified therein, subject to
         Section 4.01 hereof. Any installment of interest or principal, if any,
         payable on any Note which is punctually paid or duly provided for by
         the Issuer on the applicable Distribution Date shall be paid to the
         Person in whose name such Note is registered on the Record Date by
         check mailed first-class, postage prepaid to such Person's address as
         it appears on the records of the Trustee on such Record Date, except
         that, unless definitive Notes have been issued pursuant to Section
         2.09, 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.

                  (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 B. 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

                                       24

<PAGE>

         and be continuing if the Trustee or the Registered Owners 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 6.02. The 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.

                                  ARTICLE III

                 PARITY AND PRIORITY OF LIEN; OTHER OBLIGATIONS;
                             AND DERIVATIVE PRODUCTS

         SECTION 3.01. PARITY AND PRIORITY OF LIEN. The provisions, covenants
and agreements herein set forth to be performed by or on behalf of the Issuer
shall be for the equal benefit, protection and security of the Registered Owners
of any and all of the Obligations, all of which, shall be of equal rank without
preference, priority or distinction of any of the Obligations over any other
thereof, except as expressly provided in this Indenture with respect to certain
payment and other priorities.

         SECTION 3.02. OTHER OBLIGATIONS. The Available Funds and other moneys,
Financed Eligible Loans, securities, evidences of indebtedness, interests,
rights and properties pledged under this Indenture are and will be owned by the
Issuer free and clear of any pledge, lien, charge or encumbrance thereon or with
respect thereto prior to, of equal rank with or subordinate to the respective
pledges created by this Indenture, except as otherwise expressly provided
herein, and all action on the part of the Issuer to that end has been duly and
validly taken. If any Financed Eligible Loan is found to have been subject to a
lien at the time such Financed Eligible Loan was acquired, the Issuer shall
cause such lien to be released, shall purchase such Financed Eligible Loan from
the Trust Estate for a purchase price equal to its principal amount plus any
unamortized premium, if any, and interest accrued thereon or shall replace such
Financed Eligible Loan with another Eligible Loan with substantially identical
characteristics which replacement Eligible Loan shall be free and clear of liens
at the time of such replacement. Except as otherwise provided herein, the Issuer
shall not create or voluntarily permit to be created any debt, lien or charge on
the Financed Eligible Loans which would be on a parity with, subordinate to, or
prior to the lien of this Indenture; shall not do or omit to do or suffer to be
done or omitted to be done any matter or things whatsoever whereby the lien of
this Indenture or the priority of such lien for the Obligations hereby secured
might or could be lost or impaired; and will pay or cause to be paid or will
make adequate provisions for the satisfaction and discharge of all lawful claims
and demands which if unpaid might by law be given precedence to or any equality
with this Indenture as a lien or charge upon the Financed Eligible Loans;
provided, however, that nothing in this Section 3.02 shall require the Issuer to
pay, discharge or make provision for any such lien, charge, claim or demand so
long as the validity thereof shall be by it in good faith contested, unless
thereby, in the opinion of the Trustee, the same will endanger the security for
the Obligations; and provided further that any subordinate lien hereon

                                       25

<PAGE>

(i.e., subordinate to the lien securing the Class A Obligations and the Class B
Obligations) shall be entitled to no payment from the Trust Estate, nor may any
remedy be exercised with respect to such subordinate lien against the Trust
Estate until all Obligations have been paid or deemed paid hereunder.

         SECTION 3.03. DERIVATIVE PRODUCTS; COUNTERPARTY PAYMENTS; ISSUER
DERIVATIVE PAYMENTS. The Issuer hereby authorizes and directs the Trustee to
acknowledge and agree to any Derivative Product hereafter entered into by the
Issuer and a Counterparty under which (a) the Issuer may be required to make,
from time to time, payments to a Counterparty and (b) the Trustee may receive,
from time to time, Counterparty Payments for the account of the Issuer. No
Derivative Product shall be entered into subsequent to the Date of Issuance
unless the Trustee shall have received a Rating Confirmation from each Rating
Agency that such Derivative Product will not adversely affect the Rating on any
of the Notes.

                                   ARTICLE IV

                       PROVISIONS APPLICABLE TO THE NOTES;
                              DUTIES OF THE ISSUER

         SECTION 4.01. PAYMENT OF PRINCIPAL AND INTEREST. The Issuer covenants
that it will promptly pay, but solely from the Trust Estate, the principal of
and interest, if any, on each and every Obligation issued under the provisions
of this Indenture at the places, on the dates and in the manner specified herein
and in said Obligations according to the true intent and meaning thereof. The
Obligations shall be and are hereby declared to be payable from and equally
secured by an irrevocable first lien on and pledge of the properties
constituting the Trust Estate, subject to the application thereof as permitted
by this Indenture, but in no event shall the Registered Owners or any
Counterparty have any right to possession or control of any Financed Eligible
Loans, which shall be held only by the Trustee or its agent or bailee.

         SECTION 4.02. COVENANTS AS TO ADDITIONAL CONVEYANCES. At any and all
times, the Issuer will duly execute, acknowledge and deliver, or will cause to
be done, executed and delivered, all and every such further acts, conveyances,
transfers and assurances in law as the Trustee shall reasonably require for the
better conveying, transferring and pledging and confirming unto the Trustee, all
and singular, the properties constituting the Trust Estate hereby transferred
and pledged, or intended so to be transferred and pledged.

         SECTION 4.03. FURTHER COVENANTS OF THE ISSUER.

                  (a)      The Issuer will cause financing statements and
         continuation statements with respect thereto at all times to be filed
         in the office of the Secretary of State of the State and any other
         jurisdiction necessary to perfect and maintain the security interest
         granted by the Issuer hereunder.

                  (b)      The Issuer will duly and punctually keep, observe and
         perform each and every term, covenant and condition on its part to be
         kept, observed and performed, contained in this Indenture and the other
         agreements to which the Issuer is a party pursuant to the transactions
         contemplated herein, including but not limited to the Basic

                                       26

<PAGE>

         Documents, and will punctually perform all duties required by the Trust
         Agreement and the laws of the State.

                  (c)      The Issuer shall be operated on the basis of its
         Fiscal Year.

                  (d)      The Issuer shall cause to be kept full and proper
         books of records and accounts, in which full, true and proper entries
         will be made of all dealings, business and affairs of the Issuer which
         relate to the Notes and any Derivative Product.

                  (e)      The Issuer, upon written request of the Trustee, will
         permit at all reasonable times the Trustee or its agents, accountants
         and attorneys, to examine and inspect the property, books of account,
         records, reports and other data relating to the Financed Eligible
         Loans, and will furnish the Trustee such other information as it may
         reasonably request. The Trustee shall be under no duty to make any such
         examination unless requested in writing to do so by the Registered
         Owners of 66% in collective aggregate principal amount of the Notes at
         the time Outstanding, and unless such Registered Owners shall have
         offered the Trustee security and indemnity satisfactory to it against
         any costs, expenses and liabilities which might be incurred thereby.

                  (f)      The Issuer shall cause an annual audit to be made by
         an independent auditing firm of national reputation and file one copy
         thereof with the Trustee and each Rating Agency within 150 days of the
         close of each Fiscal Year. The Trustee shall be under no obligation to
         review or otherwise analyze such audit.

                  (g)      The Issuer covenants that all Financed Eligible Loans
         upon receipt thereof shall be delivered to the Trustee or its agent or
         bailee to be held pursuant to this Indenture and pursuant to the
         Servicing Agreement or a Custodian Agreement.

                  (h)      Notwithstanding anything to the contrary contained
         herein, except upon the occurrence and during the continuance of an
         Event of Default hereunder, the Issuer hereby expressly reserves and
         retains the privilege to receive and, subject to the terms and
         provisions of this Indenture, to keep or dispose of, claim, bring suits
         upon or otherwise exercise, enforce or realize upon its rights and
         interest in and to the Financed Eligible Loans and the proceeds and
         collections therefrom, and neither the Trustee nor any Registered Owner
         shall in any manner be or be deemed to be an indispensable party to the
         exercise of any such privilege, claim or suit and the Trustee shall be
         under no obligation whatsoever to exercise any such privilege, claim or
         suit; provided, however, that the Trustee shall have and retain
         possession or control of the Financed Eligible Loans pursuant to
         Section 5.02 hereof (which Financed Eligible Loans may be held by the
         Trustee's agent or bailee) so long as such loans are subject to the
         lien of this Indenture.

                  (i)      The Issuer shall notify the Trustee and each Rating
         Agency in writing prior to entering into any Derivative Product.

         SECTION 4.04. ENFORCEMENT OF SERVICING AGREEMENTS. The Issuer shall
comply with and shall require the Servicer to comply with the following whether
or not the Issuer is otherwise in default under this Indenture:

                                       27
<PAGE>

                  (a)      cause to be diligently enforced and taken all
         reasonable steps, actions and proceedings necessary for the enforcement
         of all terms, covenants and conditions of all Servicing Agreements,
         including the prompt payment of all amounts due the Issuer thereunder,
         including, without limitation, all principal and interest payments, and
         Guarantee payments which relate to any Financed Eligible Loans and
         cause the Servicer to specify whether payments received by it represent
         principal or interest;

                  (b)      not permit the release of the obligations of any
         Servicer under any Servicing Agreement except in conjunction with
         amendments or modifications permitted by (h) below;

                  (c)      at all times, to the extent permitted by law, cause
         to be defended, enforced, preserved and protected the rights and
         privileges of the Issuer, the Trustee and the Registered Owners under
         or with respect to each Servicing Agreement;

                  (d)      at its own expense, the Issuer shall duly and
         punctually perform and observe each of its obligations to the Servicer
         under the Servicing Agreement in accordance with the terms thereof;

                  (e)      the Issuer agrees to give the Trustee and the Rating
         Agency prompt written notice of each default on the part of the
         Servicer of its obligations under the Servicing Agreement coming to the
         Issuer's attention;

                  (f)      the Issuer shall not waive any default by the
         Servicer under the Servicing Agreement without the written consent of
         the Trustee and the giving of written notice to the Rating Agency;

                  (g)      the Issuer shall cause Nelnet, Inc., as master
         servicer, to deliver to the Trustee and the Issuer, on or before June
         30 of each year, beginning with June 30, 2004, a certificate stating
         that (i) a review of the activities of the Servicer during the
         preceding calendar year and of its performance under the Servicing
         Agreement has been made under the supervision of the officer signing
         such certificate and (ii) to the best of such officers' knowledge,
         based on such review, the Servicer has fulfilled all its obligations
         under the Servicing Agreement throughout such year, or, there has been
         a default in the fulfillment of any such obligation, specifying each
         such default known to such officer and the nature and stature thereof.
         The Issuer shall send copies of such annual certificate of the Servicer
         to each Rating Agency; and

                  (h)      not consent or agree to or permit any amendment or
         modification of any Servicing Agreement which will in any manner
         materially adversely affect the rights or security of the Registered
         Owners. The Issuer shall be entitled to receive and rely upon an
         opinion of its counsel that any such amendment or modification will not
         materially adversely affect the rights or security of the Registered
         Owners.

         SECTION 4.05. PROCEDURES FOR TRANSFER OF FUNDS. In any instance where
this Indenture requires a transfer of funds or money from one Fund to another, a
transfer of ownership in investments or an undivided interest therein may be
made in any manner agreeable to the Issuer and the Trustee, and in the
calculation of the amount transferred, interest on the investment

                                       28

<PAGE>

which has or will accrue before the date the money is needed in the fund to
which the transfer is made shall not be taken into account or considered as
money on hand at the time of such transfer.

         SECTION 4.06. ADDITIONAL COVENANTS WITH RESPECT TO THE ACT. The Issuer
covenants that it will cause the Trustee to be, or replace the Trustee with, an
Eligible Lender under the Act, that it will acquire or cause to be acquired
Eligible Loans originated and held only by an Eligible Lender and that it will
not dispose of or deliver any Financed Eligible Loans or any security interest
in any such Financed Eligible Loans to any party who is not an Eligible Lender
so long as the Act or Regulations adopted thereunder require an Eligible Lender
to be the owner or holder of Guaranteed Eligible Loans; provided, however, that
nothing above shall prevent the Issuer from delivering the Eligible Loans to the
Servicer or the Guarantee Agency. The Registered Owners of the Notes shall not
in any circumstances be deemed to be the owner or holder of the Guaranteed
Eligible Loans.

         The Issuer, or the Administrator on behalf of the Issuer, shall be
responsible for each of the following actions with respect to the Act:

                  (a)      the Issuer, or the Administrator on behalf of the
         Issuer, shall be responsible for dealing with the Secretary with
         respect to the rights, benefits and obligations under the Certificates
         of Insurance and the Contract of Insurance, and the Issuer shall be
         responsible for dealing with the Guarantee Agencies with respect to the
         rights, benefits and obligations under the Guarantee Agreements with
         respect to the Financed Eligible Loans;

                  (b)      the Issuer, or the Administrator on behalf of the
         Issuer, shall cause to be diligently enforced, and shall cause to be
         taken all reasonable steps, actions and proceedings necessary or
         appropriate for the enforcement of all terms, covenants and conditions
         of all Financed Eligible Loans and agreements in connection therewith,
         including the prompt payment of all principal and interest payments and
         all other amounts due thereunder;

                  (c)      the Issuer, or the Administrator on behalf of the
         Issuer, shall cause the Financed Eligible Loans to be serviced by
         entering into the Servicing Agreement or other agreement with the
         Servicer for the collection of payments made for, and the
         administration of the accounts of, the Financed Eligible Loans;

                  (d)      the Issuer, or the Administrator on behalf of the
         Issuer, shall comply, and shall cause all of its officers, directors,
         employees and agents to comply, with the provisions of the Act and any
         regulations or rulings thereunder, with respect to the Financed
         Eligible Loans;

                  (e)      the Issuer, or the Administrator on behalf of the
         Issuer, shall cause the benefits of the Guarantee Agreements, the
         Interest Benefit Payments and the Special Allowance Payments to flow to
         the Trustee. The Trustee shall have no liability for actions taken at
         the direction of the Issuer or the Administrator, except for negligence
         or willful misconduct in the performance of its express duties
         hereunder. The Trustee shall

                                       29

<PAGE>

         have no obligation to administer, service or collect the loans in the
         Trust Estate or to maintain or monitor the administration, servicing or
         collection of such loans; and

                  (f)      the Issuer, or the Administrator on behalf of the
         Issuer, shall cause each Financed Eligible Loan evidenced by a Master
         Promissory Note in the form mandated by Section 432(m)(1) of the Act to
         be acquired pursuant to a Student Loan Purchase Agreement with a Seller
         containing language similar to the following:

                           "The Seller hereby represents and warrants that the
                  Seller is transferring all of its right title and interest in
                  the MPN Loan to the Trustee, that it has not assigned any
                  interest in such MPN Loan (other than security interests that
                  have been released or ownership interests that the Seller has
                  reacquired) to any person other than the Trustee, and that no
                  prior holder of the MPN Loan has assigned any interest in such
                  MPN Loan (other than security interests that have been
                  released or ownership interests that such prior holder has
                  reacquired) to any person other than a predecessor in title to
                  the Seller. The Seller hereby covenants that the Seller shall
                  not attempt to transfer to any other person any interest in
                  any MPN Loan assigned hereunder. The Seller hereby authorizes
                  the Trustee to file a UCC-1 financing statement identifying
                  the Seller as debtor and the Trustee as secured party and
                  describing the MPN Loan sold pursuant to this Agreement. The
                  preparation or filing of such UCC-1 financing statement is
                  solely for additional protection of the Trustee's interest in
                  the MPN Loans and shall not be deemed to contradict the
                  express intent of the Seller and the Trustee that the transfer
                  of MPN Loans under this Agreement is an absolute assignment of
                  such MPN Loans and is not a transfer of such MPN Loans as
                  security for a debt."

         The Trustee shall not be deemed to be the designated agent for the
purposes of this Section 4.06 unless it has agreed in writing to be such agent.

         SECTION 4.07. FINANCED ELIGIBLE LOANS; COLLECTIONS THEREOF; ASSIGNMENT
THEREOF. The Issuer, through the Servicer, shall diligently collect all
principal and interest payments on all Financed Eligible Loans, and all Interest
Benefit Payments, insurance, guarantee and default claims and Special Allowance
Payments which relate to such Financed Eligible Loans. The Issuer shall cause
the filing and assignment of such claims (prior to the timely filing deadline
for such claims under the Regulations) by the Servicer. The Issuer will comply
with the Act and Regulations which apply to the Program and to such Financed
Eligible Loans.

         SECTION 4.08. APPOINTMENT OF AGENTS, DIRECTION TO TRUSTEE, ETC. The
Issuer shall employ and appoint all employees, agents, consultants and attorneys
which it may consider necessary. No member of the board of directors or officer
of the Administrator, neither singly or collectively, shall be personally liable
for any act or omission not willfully fraudulent or mala fide. The Issuer hereby
directs the Trustee to enter into this Indenture, the Administration Agreement,
the Custodian Agreements, the Guarantee Agreements, the Investment Agreement,
and the Eligible Lender Trust Agreements.

         SECTION 4.09. CAPACITY TO SUE. The Issuer shall have the power and
capacity to sue and to be sued on matters arising out of or relating to the
financing of the Financed Eligible Loans.

                                       30

<PAGE>

         SECTION 4.10. CONTINUED EXISTENCE; SUCCESSOR TO ISSUER. The Issuer
agrees that it will do or cause to be done all things necessary to preserve and
keep in full force and effect its existence, rights and franchises as a Delaware
statutory trust, except as otherwise permitted by this Section 4.10. The Issuer
further agrees that it will not (a) sell, transfer or otherwise dispose of all
or substantially all, of its assets (except Financed Eligible Loans if such
sale, transfer or disposition will discharge this Indenture in accordance with
Article X hereof); (b) consolidate with or merge into another entity; or (c)
permit one or more other entities to consolidate with or merge into it. The
preceding restrictions in (a), (b) and (c) shall not apply to a transaction if
the transferee or the surviving or resulting entity, if other than the Issuer,
by proper written instrument for the benefit of the Trustee, irrevocably and
unconditionally assumes the obligation to perform and observe the agreements and
obligations of the Issuer under this Indenture.

         If a transfer is made as provided in this Section, the provisions of
this Section shall continue in full force and effect and no further transfer
shall be made except in compliance with the provisions of this Section.

         SECTION 4.11. AMENDMENT OF STUDENT LOAN PURCHASE AGREEMENTS. The Issuer
shall notify the Trustee in writing of any proposed amendments to any existing
Student Loan Purchase Agreement. No such amendment shall become effective unless
and until the Trustee consents thereto in writing. The consent of the Trustee
shall not be unreasonably withheld and shall not be withheld if the Trustee
receives an opinion of counsel acceptable to them that such an amendment is
required by the Act and is not prejudicial to the Registered Owners.
Notwithstanding the foregoing, however, the Trustee shall consent to an
amendment from time to time so long as it is not materially prejudicial to the
interests of the Registered Owners, and the Trustee may rely on an opinion of
counsel to such effect.

         SECTION 4.12. REPRESENTATIONS; NEGATIVE COVENANTS.

                  (a)      The Issuer hereby makes the following representations
         and warranties to the Trustee on which the Trustee relies in
         authenticating the Notes and on which the Registered Owners have relied
         in purchasing the Notes. Such representations and warranties shall
         survive the transfer and assignment of the Trust Estate to the Trustee.

                           (i)      Organization and Good Standing. The Issuer
                  is duly organized and validly existing under the laws of the
                  State, and has the power to own its assets and to transact the
                  business in which it presently engages.

                           (ii)     Due Qualification. The Issuer is duly
                  qualified to do business and is in good standing, and has
                  obtained all material necessary licenses and approvals, in all
                  jurisdictions where the failure to be so qualified, have such
                  good standing or have such licenses or approvals would have a
                  material adverse effect on the Issuer's business and
                  operations or in which the actions as required by this
                  Indenture require or will require such qualification.

                           (iii)    Authorization. The Issuer has the power,
                  authority and legal right to create and issue the Notes, to
                  execute, deliver and perform this Indenture and to grant the
                  Trust Estate to the Trustee and the creation and issuance of
                  the Notes,

                                       31

<PAGE>

                  execution, delivery and performance of this Indenture and
                  grant of the Trust Estate to the Trustee have been duly
                  authorized by the Issuer by all necessary statutory trust
                  action.

                           (iv)     Binding Obligation. This Indenture, assuming
                  due authorization, execution and delivery by the Trustee, the
                  Notes in the hands of the Registered Owners thereof and the
                  Issuer Derivative Payments constitute legal, valid and binding
                  obligations of the Issuer enforceable against the Issuer in
                  accordance with their terms, except that (A) such enforcement
                  may be subject to bankruptcy, insolvency, reorganization,
                  moratorium or other similar laws (whether statutory,
                  regulatory or decisional) now or hereafter in effect relating
                  to creditors' rights generally and (B) the remedy of specific
                  performance and injunctive and other forms of equitable relief
                  may be subject to certain equitable defenses and to the
                  discretion of the court before which any proceeding therefor
                  may be brought, whether a proceeding at law or in equity.

                           (v)      No Violation. The consummation of the
                  transactions contemplated by this Indenture and the
                  fulfillment of the terms hereof does not conflict with, result
                  in any breach of any of the terms and provisions of or
                  constitute (with or without notice, lapse of time or both) a
                  default under the organizational documents of the Issuer, or
                  any material indenture, agreement, mortgage, deed of trust or
                  other instrument to which the Issuer is a party or by which it
                  is bound, or result in the creation or imposition of any lien
                  upon any of its material properties pursuant to the terms of
                  any such indenture, agreement, mortgage, deed of trust or
                  other instrument, other than this Indenture, nor violate any
                  law or any order, rule or regulation applicable to the Issuer
                  of any court or of any federal or state regulatory body,
                  administrative agency or other governmental instrumentality
                  having jurisdiction over the Issuer or any of its properties.

                           (vi)     No Proceedings. There are no proceedings,
                  injunctions, writs, restraining orders or investigations to
                  which the Issuer or any of such entity's affiliates is a party
                  pending, or, to the best of such entity's knowledge,
                  threatened, before any court, regulatory body, administrative
                  agency or other tribunal or governmental instrumentality (A)
                  asserting the invalidity of this Indenture, (B) seeking to
                  prevent the issuance of any Notes or the consummation of any
                  of the transactions contemplated by this Indenture or (C)
                  seeking any determination or ruling that might materially and
                  adversely affect the performance by the Issuer of its
                  obligations under, or the validity or enforceability of this
                  Indenture.

                           (vii)    Approvals. All approvals, authorizations,
                  consents, orders or other actions of any person, corporation
                  or other organization, or of any court, governmental agency or
                  body or official, required on the part of the Issuer in
                  connection with the execution and delivery of this Indenture
                  have been taken or obtained on or prior to the Date of
                  Issuance.

                                       32

<PAGE>

                           (viii)   Place of Business. The Issuer's place of
                  business and chief executive office is located in Wilmington,
                  Delaware and the Issuer has had no other chief executive
                  office.

                           (ix)     Tax and Accounting Treatment. The Issuer
                  intends to treat the transactions contemplated by the Student
                  Loan Purchase Agreements as an absolute transfer rather than
                  as a pledge of the Financed Eligible Loans from the Seller for
                  federal income tax and financial accounting purposes and the
                  Issuer will be treated as the owner of the Financed Eligible
                  Loans for all purposes. The Issuer further intends to treat
                  the Notes as its indebtedness for federal income tax and
                  financial accounting purposes.

                           (x)      Taxes. The Issuer has filed (or caused to be
                  filed) all federal, state, county, local and foreign income,
                  franchise and other tax returns required to be filed by it
                  through the date hereof, and has paid all taxes reflected as
                  due thereon. There is no pending dispute with any taxing
                  authority that, if determined adversely to the Issuer, would
                  result in the assertion by any taxing authority of any
                  material tax deficiency, and the Issuer has no knowledge of a
                  proposed liability for any tax year to be imposed upon such
                  entity's properties or assets for which there is not an
                  adequate reserve reflected in such entity's current financial
                  statements.

                           (xi)     Legal Name. The legal name of the Issuer is
                  "Nelnet Student Loan Trust 2003-1" and has not changed since
                  its inception. The Issuer has no trade names, fictitious
                  names, assumed names or "dba's" under which it conducts its
                  business and has made no filing in respect of any such name.

                           (xii)    Business Purpose. The Issuer has acquired
                  the Financed Eligible Loans conveyed to it under a Student
                  Loan Purchase Agreement for a bona fide business purpose and
                  has undertaken the transactions contemplated herein as
                  principal rather than as an agent of any other person. The
                  Issuer has no subsidiaries, has adopted and operated
                  consistently with all requirements for statutory trusts under
                  the laws of the State with respect to its operations and has
                  engaged in no other activities other than those specified in
                  this Indenture and the Student Loan Purchase Agreements and in
                  accordance with the transactions contemplated herein and
                  therein.

                           (xiii)   Compliance with Laws. The Issuer is in
                  compliance with all applicable laws and regulations with
                  respect to the conduct of its business and has obtained and
                  maintains all permits, licenses and other approvals as are
                  necessary for the conduct of its operations.

                           (xiv)    Valid Business Reasons; No Fraudulent
                  Transfers. The transactions contemplated by this Indenture are
                  in the ordinary course of the Issuer's business and the Issuer
                  has valid business reasons for granting the Trust Estate
                  pursuant to this Indenture. At the time of each such grant:
                  (A) the Issuer granted the Trust Estate to the Trustee without

                  defraud any current or future creditor of the Issuer; (B) the
                  Issuer was not insolvent and did not become insolvent as a
                  result of any such grant; (C) the Issuer was not engaged and
                  was not about to engage in any business or transaction for
                  which any property remaining with such entity was an
                  unreasonably small capital or for which the remaining assets
                  of such entity are unreasonably small in relation to the
                  business of such entity or the transaction; (D) the Issuer did
                  not intend to incur, and did not believe or should not have
                  reasonably believed, that it would incur, debts beyond its
                  ability to pay as they become due; and (E) the consideration
                  paid received by the Issuer for the grant of the Trust Estate

                  Administration Agreement or the payment of dividends or
                  distributions to the Issuer's parent.

                           (xvii)   Ability to Perform. There has been no
                  material impairment in the ability of the Issuer to perform

                  occurred and no event has occurred that, with the giving of
                  notice, the passage of time, or both, would become an Event of
                  Default.

                           (xx)     Acquisition of Financed Eligible Loans

                  acquisition of the Financed Eligible Loans from the Seller.

                           (xxi)    No Material Misstatements or Omissions. No
                  information, certificate of an officer, statement furnished in
                  writing or report delivered to the Trustee, the Servicer or
                  any Registered Owner by the Issuer contains any untrue
                  statement of a material fact or omits a material fact
                  necessary to make such information, certificate, statement or
                  report not misleading.

         warranties as to the Trust Estate which is granted to the Trustee
         hereunder on such date, on which the Trustee relies in accepting the

         grant of the Trust Estate to the Trustee pursuant to this Indenture:

                           (i)      Financed Eligible Loans. Each Financed
                  Eligible Loan acquired by the Issuer shall constitute an
                  Eligible Loan and contain the characteristics found in a
                  Student Loan Purchase Agreement. Notwithstanding the
                  definition of "Eligible Loans" herein, the Issuer covenants
                  that no more than 20% of each purchase of Eligible Loans will
                  be made up of Eligible Loans delinquent by more than 30 days.

                           (ii)     Grant. It is the intention of the Issuer
                  that the transfer herein contemplated constitutes a grant of

                           (iii)    All Filings Made. All filings (including,
                  without limitation, UCC filings) necessary in any jurisdiction
                  to give the Trustee a first priority perfected ownership and
                  security interest in the Trust Estate, including the Financed
                  Eligible Loans, have been made no later than the Date of
                  Issuance and copies of the file-stamped financing statements
                  shall be delivered to the Trustee within five Business Days of
                  receipt by the Issuer or its agent from the appropriate
                  secretary of state. The Issuer has not caused, suffered or
                  permitted any lien, pledges, offsets, defenses, claims,
                  counterclaims, charges or security interest with respect to
                  the Financed Eligible Loans (other than the security interest
                  created in favor of the Trustee) to be created.

                           (iv)     Transfer Not Subject to Bulk Transfer Act.
                  Each grant of the Financed Eligible Loans by the Issuer
                  pursuant to this Indenture is not subject to the bulk transfer
                  act or any similar statutory provisions in effect in any
                  applicable jurisdiction.

                           (v)      No Transfer Taxes Due. Each grant of the
                  Financed Eligible Loans (including all payments due or to
                  become due thereunder) by the Issuer pursuant to this
                  Indenture is not subject to and will not result in any tax,
                  fee or governmental charge payable by the Issuer or the Seller
                  to any federal, state or local government.

         security interest (as defined in the applicable Uniform Commercial Code
         in effect in the States of Delaware, Nebraska and Colorado) in the
         Financed Eligible Loans in favor of the Trustee, which security
         interest is prior to all other liens, charges, security interests,
         mortgages or other encumbrances, and is enforceable as such as against
         creditors of and purchasers from Issuer.

                  (b)      The Financed Eligible Loans constitute "accounts"
         within the meaning of the applicable UCC.

                  (c)      The Issuer owns and has good and marketable title to
         the Financed Eligible Loans free and clear of any lien, charge,
         security interest, mortgage or other encumbrance, claim or encumbrance
         of any Person, other that those granted pursuant to this Indenture.

                  (d)      For sale of loan participations, swaps and other
         "payment intangibles" (within the meaning of the applicable UCC), the
         Issuer has received all consents and approvals required by the terms of
         the Financed Eligible Loans to the sale of the Financed Eligible Loans
         hereunder to the Trustee.

                  (e)      The Issuer has caused or will have caused, within ten
         days, the filing of all appropriate financing statements in the proper
         filing office in the appropriate jurisdictions under applicable law in
         order to perfect the security interest in the Financed Eligible Loans
         granted to the Trustee hereunder.

<PAGE>

                  (f)      The Issuer has received a written acknowledgment from
         the Servicer (as custodian for the Trustee) that the Servicer is
         holding executed copies of the promissory notes and master promissory
         notes that constitute or evidence the Financed Eligible Loans, and that
         the Servicer is holding such solely on behalf and for the benefit of
         the Trustee.

                  (g)      Other than the security interest granted to the
         Trustee pursuant to this Indenture, the Issuer has not pledged,
         assigned, sold, granted a security interest in, or otherwise conveyed
         any of the Financed Eligible Loans. The Issuer has not authorized the
         filing of and is not aware of any financing statements against the
         Issuer that include a description of collateral covering the Financed
         Eligible Loans other than any financing statement relating to the
         security interest granted to the Trustee hereunder or that has been
         terminated. The Issuer is not aware of any judgment or tax lien filings
         against the Issuer.

         SECTION 4.18. FURTHER COVENANTS OF THE ISSUER REGARDING THE TRUSTEE'S
SECURITY INTEREST. The Issuer hereby covenants for the benefit of the Trustee
and the Registered Owners as follows:

                  (a)      The representations and warranties set forth in
         Section 4.17 shall survive the termination of this Indenture.

                  (b)      The Trustee shall not waive any of the
         representations and warranties set forth in Section 4.17 above.

                  (c)      The Issuer shall take all steps necessary, and shall
         cause the Servicers and subservicers, if any, to take all steps
         necessary and appropriate, to maintain the perfection and priority of
         the Trustee's security interest in the Financed Eligible Loans.

                                    ARTICLE V

                                      FUNDS

         SECTION 5.01. CREATION AND CONTINUATION OF FUNDS AND ACCOUNTS. There
are hereby created and established the following Funds to be held and maintained
by the Trustee for the benefit of the Registered Owners:

                  (a)      Acquisition Fund;

                  (b)      Collection Fund; and

                  (c)      Reserve Fund.

         The Trustee is hereby authorized for the purpose of facilitating the
administration of the Trust Estate and for the administration of any Notes
issued hereunder to create further Accounts or Subaccounts in any of the various
Funds and Accounts established hereunder which are deemed necessary or
desirable.

                                       40

<PAGE>

         SECTION 5.02. ACQUISITION FUND. There shall be deposited into the
Acquisition Fund moneys from proceeds of the Notes in an amount equal to
$993,850,432. Financed Eligible Loans shall be held by the Trustee or its agent
or bailee (including the Servicer) and shall be pledged to the Trust Estate and
accounted for as a part of the Acquisition Fund.

         Moneys on deposit in the Acquisition Fund shall be used, upon Issuer
Order, solely to (a) pay costs of issuance of the Notes, including the costs
related to the purchase of one or more Derivative Products, and (b) upon receipt
by the Trustee of an Eligible Loan Acquisition Certificate, to acquire Eligible
Loans at a price not in excess of 101.00%, plus accrued interest. Any such
Issuer Order or Eligible Loan Acquisition Certificate shall state that such
proposed use of moneys in the Acquisition Fund is in compliance with the
provisions of this Indenture. An Authorized Representative of the Issuer may, by
Issuer Order, direct the Trustee to transfer any or all such moneys to the
Collection Fund for use therein. Notwithstanding the foregoing, if any funds or
moneys remain in the Acquisition Fund on April 25, 2003, then the Trustee shall,
without direction from or notice to the Issuer, transfer all such remaining
moneys or funds to the Collection Fund not later than the third Business Day
preceding the Distribution Date in July, 2003.

         While the Issuer will be the beneficial owner of the Financed Eligible
Loans and the Registered Owners will have a security interest therein, it is
understood and agreed that the Trustee will be the legal owner thereof and will
have a security interest in the Financed Eligible Loans for and on behalf of the
Registered Owners. In the case of a single Financed Eligible Loan evidenced by a
separate note, each such note will be held in the name of the Trustee for the
account of the Issuer, for the benefit of the Registered Owners. In the case of
a Financed Eligible Loan evidenced by a Master Promissory Note, the Issuer shall
cause the holder of the original Master Promissory Note to indicate by book
entry on its books and records that the Issuer is the beneficial owner of the
Loan and that the Trustee is the legal owner and has a security interest in the
Financed Eligible Loan for the benefit of the Registered Owners.

         Except as provided in Sections 5.06, 10.03 and 10.04 hereof, Financed
Eligible Loans shall not be sold, transferred or otherwise disposed of (other
than for consolidation, serialization or transfer to a Guaranty Agency) by the
Trustee free from the lien of this Indenture.

         SECTION 5.03. COLLECTION FUND.

                  (a)      There shall be deposited into the Collection Fund
         $6,493,617 from proceeds of the Notes. There shall also be deposited to
         the Collection Fund all Available Funds, and all other moneys and
         investments derived from assets on deposit in and transfers from the
         Acquisition Fund and the Reserve Fund, all Counterparty Payments and
         any other amounts deposited thereto upon receipt of an Issuer Order.
         Moneys on deposit in the Collection Fund shall be used to make the
         payments described below. The Trustee may conclusively rely on all
         written instructions of the Administrator described in this Indenture
         with no further duty to examine or determine the information contained
         in any Administrator's Certificate or Issuer Order.

                  (b)      The Administrator shall instruct the Trustee in
         writing no later than the fourth Business Day preceding each Monthly
         Servicing Payment Date that is not a

                                       41

<PAGE>

         Distribution Date (based on the information contained in a certificate
         of the Administrator (in the form set forth as Exhibit C hereto) and
         the related Servicer's Report) to distribute to the Servicer, by 1:00
         p.m. (New York time) on such Monthly Servicing Payment Date, from and
         to the extent of the Available Funds on deposit in the Collection Fund,
         the Servicing Fee due with respect to the preceding calendar month, and
         the Trustee shall comply with such instructions. Upon written direction
         from the Administrator to the Trustee, moneys in the Collection Fund
         shall be used on any date to pay, when due, fees and expenses insofar
         as the same relate to Financed Eligible Loans and other fees and
         expenses with respect to the Trust Estate the payment of which is not
         otherwise provided for in Section 5.03(c), but including amounts
         described in clause (a)(i), (ii) and (iii) of the definition of
         Available Funds.

                  (c)      The Administrator shall instruct the Trustee in
         writing no later than the fourth Business Day preceding each
         Distribution Date (based on the information contained in a certificate
         of the Administrator (in the form set forth as Exhibit D hereto) and
         the related Servicer's Report) to make the following deposits and
         distributions to the Persons or to the account specified below by 1:00
         p.m. (New York time) on such Distribution Date, to the extent of (x)
         the amount of Available Funds in the Collection Fund and (y) the amount
         transferred from the Reserve Fund pursuant to Section 5.04(b), (c) and
         (d), in the following order of priority, and the Trustee shall comply
         with such instructions:

                           (i)      to the Servicer, the Servicing Fee, and to
                  the Trustee and the Delaware Trustee, the Trustee Fee and the
                  Delaware Trustee Fee, respectively, ratably, without
                  preference or priority of any kind, due on such Distribution
                  Date;

                           (ii)     to the Administrator, the Administration Fee
                  due on such Distribution Date and all unpaid Administration
                  Fees from prior Distribution Dates;

                           (iii)    to the Class A-1 Noteholders, Class A-2
                  Noteholders, Class A-3 Noteholders and Class A-4 Noteholders,
                  the Class A Noteholders' Interest Distribution Amount,
                  ratably, without preference or priority of any kind, according
                  to the amounts payable on the Class A Notes in respect of
                  Class A Noteholders' Interest Distribution Amount;

                           (iv)     to the Class B Noteholders, the Class B
                  Noteholders' Interest Distribution Amount, ratably, without
                  preference or priority of any kind, according to the amounts
                  payable in respect of Class B Noteholders' Interest
                  Distribution Amount;

                           (v)      to the Sponsor, an amount equal to the
                  unpaid interest accrued on the Financed Student Loans
                  subsequent to the Cutoff Date but prior to the Date of
                  Issuance, until such amount has been paid in full;

                           (vi)     to the Class A-1 Noteholders until the Class
                  A-1 Notes have been paid in full, the Class A Noteholders'
                  Principal Distribution Amount;

                                       42

<PAGE>

                           (vii)    on each Distribution Date on and after the
                  date on which the Class A-1 Notes have been paid in full, to
                  the Class A-2 Noteholders until the Class A-2 Notes are paid
                  in full, the Class A Noteholders' Principal Distribution
                  Amount;

                           (viii)   on each Distribution Date on and after the
                  date on which the Class A-1 Notes and the Class A-2 Notes have
                  been paid in full, to the Class A-3 Noteholders until the
                  Class A-3 Notes are paid in full, the Class A Noteholders'
                  Principal Distribution Amount;

                           (ix)     on each Distribution Date on and after the
                  date on which the Class A-1 Notes, the Class A-2 Notes and the
                  Class A-3 Notes have been paid in full, to the Class A-4
                  Noteholders, pro rata, until the Class A-4 Notes are paid in

                           (x)      on each Distribution Date on and after which
                  the Class A Notes have been paid in full, to the Class B
                  Noteholders until the Class B Notes have been paid in full,
                  the Class B Noteholders' Principal Distribution Amount;

                           (xi)     to the Reserve Fund, the amount, if any,
                  necessary to reinstate the balance of the Reserve Fund up to
                  the Specified Reserve Fund Balance;

                           (xii)    to the Servicer, the aggregate unpaid amount
                  of the Carryover Servicing Fee, if any;

                           (xiii)   in the event the Financed Eligible Loans are
                  not sold pursuant to Sections 10.03 or 10.04 hereof, to pay as
                  an accelerated payment of principal balance of the Notes,
                  first to the Class A Noteholders in the same order and
                  priority as is set forth in Sections 5.03(c)(vii) through
                  (c)(x) until the principal amount of the Class A Notes is paid
                  in full and then to the Class B Noteholders until the
                  principal balance of the Class B Notes is reduced to zero; and

                           (xiv)    to the Sponsor, any remaining portion
                  thereof. Amounts properly distributed to the Sponsor pursuant
                  to this paragraph (xv) shall be deemed released from the Trust
                  Estate and the security interest therein granted to the
                  Trustee, and the Sponsor shall in no event thereafter be
                  required to refund any such distributed amounts.

         SECTION 5.04. RESERVE FUND.

                  (a)      On the Date of Issuance, the Trustee shall deposit
         $2,449,010 into the Reserve Fund. Thereafter, the Trustee shall
         transfer to the Reserve Fund from the Collection Fund all amounts
         designated for transfer thereto pursuant to Section 5.03(c)(xi) hereof.

                  (b)      On each Monthly Servicing Payment Date or
         Distribution Date, to the extent there are insufficient Available Funds
         in the Collection Fund to make one or more of the transfers required by
         Sections 5.03(b) and 5.03(c)(i) through (c)(iv), then the

                                       43

<PAGE>

         Administrator shall instruct the Trustee in writing to withdraw from
         the Reserve Fund on such Monthly Servicing Payment Date or Distribution
         Date, as the case may be, an amount equal to such deficiency and to
         deposit such amount in the Collection Fund. Additionally, if on the
         Note Final Maturity Date for a class of Notes, and after giving effect
         to the distribution of the Available Funds on such Note Final Maturity
         Date, the principal amount of such class of Notes will not be reduced
         to zero, the Administrator shall instruct the Trustee in writing to
         withdraw from the Reserve Fund on such Note Final Maturity Date an
         amount equal to the amount needed to reduce the principal amount of
         such class of Notes to zero and to deposit such amount in the
         Collection Fund.

                  (c)      After giving effect to Section 5.04(b) above, if the
         amount on deposit in the Reserve Fund on any Distribution Date is
         greater than the Specified Reserve Fund Balance for such Distribution
         Date, the Administrator shall instruct the Trustee in writing to
         withdraw from the Reserve Fund on such Distribution Date an amount
         equal to such excess and to deposit such amount in the Collection Fund.

                  (d)      [Reserved.]

                  (e)      On the final Distribution Date upon termination of
         the Trust and following the payment in full of the aggregate
         outstanding principal balance of the Notes and of all other amounts
         (other than Derivative Product Payments and Carryover Servicing Fees)
         owing or to be distributed hereunder or under the Indenture to
         Noteholders, the Trustee, the Servicer, the Administrator or the
         Counterparties, to the extent that Available Funds on such date are
         insufficient to make the following payments, amounts remaining in the
         Reserve Fund shall be used first to pay any unpaid Derivative Product
         Payments and second to pay any Carryover Servicing Fees. Any amount
         remaining on deposit in the Reserve Fund after such payments have been
         made shall be distributed to the Sponsor. The Sponsor shall in no event
         be required to refund any amounts properly distributed pursuant to this
         Section 5.04(e).

                  (f)      Anything in this Section 5.04 to the contrary
         notwithstanding, if the market value of securities and cash in the
         Reserve Fund is on any Distribution Date sufficient to pay the
         remaining principal amount of and interest accrued on the Notes, and to
         pay any unpaid Derivative Product Payments and Carryover Servicing Fee,
         such amount will be so applied on such Distribution Date and the
         Administrator shall instruct the Trustee in writing to make such
         payments.

         SECTION 5.05. INVESTMENT OF FUNDS HELD BY TRUSTEE. The Trustee is
hereby directed to enter into the Investment Agreement. In addition, the Trustee
shall invest money held for the credit of any Fund or Account or Subaccount held
by the Trustee hereunder as directed in writing (or orally, confirmed in
writing) by an Authorized Representative of the Issuer, to the fullest extent
practicable and reasonable, in Investment Securities which shall mature or be
redeemed at the option of the holder prior to the respective dates when the
money held for the credit of such Fund or Account will be required for the
purposes intended. In the absence of any such direction and to the extent
practicable, the Trustee shall invest amounts held hereunder in those Investment
Securities described in clause (k) of the definition of the Investment
Securities. All such investments shall be held by (or by any custodian on behalf
of) the Trustee for the benefit of the

                                       44

<PAGE>

Issuer; provided that on the Business Day preceding each Distribution Date all
interest and other investment income collected (net of losses and investment
expenses) on funds on deposit therein shall be deposited into the Collection
Fund and shall be deemed to constitute a portion of the Available Funds for such
Distribution Date. The Trustee and the Issuer hereby agree that unless an Event
of Default shall have occurred hereunder, the Issuer acting by and through an
Authorized Representative shall be entitled to, and shall, provide written
direction or oral direction confirmed in writing to the Trustee with respect to
any discretionary acts required or permitted of the Trustee under any Investment
Securities and the Trustee shall not take such discretionary acts without such
written direction.

         The Investment Securities purchased shall be held by the Trustee and
shall be deemed at all times to be part of such Fund or Account or Subaccounts
or combination thereof, and the Trustee shall inform the Issuer of the details
of all such investments. Upon direction in writing (or orally, confirmed in
writing) from an Authorized Representative of the Issuer, the Trustee shall use
its best efforts to sell at the best price obtainable, or present for
redemption, any Investment Securities purchased by it as an investment whenever
it shall be necessary to provide money to meet any payment from the applicable
Fund. The Trustee shall advise the Issuer in writing, on or before the fifteenth
day of each calendar month (or such later date as reasonably consented to by the
Issuer), of all investments held for the credit of each Fund in its custody
under the provisions of this Indenture as of the end of the preceding month and
the value thereof, and shall list any investments which were sold or liquidated
for less than the par value thereof, plus accrued but unpaid interest at the
time thereof.

         Money in any Fund constituting a part of the Trust Estate may be pooled
for the purpose of making investments and may be used to pay accrued interest on
Investment Securities purchased. The Trustee and its affiliates may act as
principal or agent in the acquisition or disposition of any Investment
Securities.

         Notwithstanding the foregoing, the Trustee shall not be responsible or
liable for any losses on investments made by it hereunder or for keeping all
Funds held by it, fully invested at all times, its only responsibility being to
comply with the investment instructions of the Issuer or its designee in a
non-negligent manner.

         The Issuer acknowledges that to the extent the regulations of the
Comptroller of the Currency or other applicable regulatory agency grant the
Issuer the right to receive brokerage confirmations of security transactions,
the Issuer waives receipt of such confirmations.

         SECTION 5.06. RELEASE.

                  (a)      The Trustee shall, upon Issuer Order and subject to
         the provisions of this Indenture, take all actions reasonably necessary
         to effect the release of any Financed Eligible Loans from the lien of
         this Indenture to the extent the terms hereof permit the sale,
         disposition or transfer of such Financed Eligible Loans.

                  (b)      Subject to the payment of its fees and expenses
         pursuant to Sections 7.05 and 7.07, the Trustee may, and when required
         by the provisions of this Indenture shall, execute instruments to
         release property from the lien of this Indenture, or convey the

                                       45

<PAGE>

         Trustee's interest in the same, in a manner and under circumstances
         that are not inconsistent with the provisions of this Indenture. No
         party relying upon an instrument executed by the Trustee as provided in
         this Article V shall be bound to ascertain the Trustee's authority,
         inquire into the satisfaction of any conditions precedent or see to the
         application of any moneys.

                  (c)      The Trustee shall, at such time as there are no Notes
         Outstanding and all sums due the Trustee pursuant to Sections 7.05 and
         7.07 have been paid, release any remaining portion of the Trust Estate
         that secured the Notes from the lien of this Indenture and release to
         the Issuer or any other Person entitled thereto any funds then on
         deposit in the Funds and Accounts. The Trustee shall release property
         from the lien of this Indenture pursuant to this Section 5.06(c) only
         upon receipt of an Issuer Order, an Opinion of Counsel and (if required
         by the TIA) Independent Certificates in accordance with TIA Sections
         314(c) and 314(d)(1).

                  (d)      Subject to the provisions of this Indenture, the
         Trustee shall release property from the lien of this Indenture only
         upon receipt of an Issuer Order, an Opinion of Counsel and Independent
         Certificates in accordance with TIA Sections 314(c) and 314(d)(1) or an
         Opinion of Counsel in lieu of such Independent Certificates to the
         effect that the TIA does not require any such Independent Certificates.

                  (e)      Each Registered Owner, by the acceptance of a Note,
         acknowledges that from time to time the Trustee shall release the lien
         of this Indenture on any Financed Eligible Loan to be sold to (i) the
         Seller in accordance with the applicable Student Loan Purchase
         Agreement; (ii) to the Servicer in accordance with the Servicing
         Agreement; and (iii) to another eligible lender holding one or more
         serial loans with respect to such Financed Eligible Loan, in accordance
         with the Servicing Agreement, and each Registered Owner, by the
         acceptance of a Note, consents to any such release.

                                   ARTICLE VI

                              DEFAULTS AND REMEDIES

         SECTION 6.01. EVENTS OF DEFAULT DEFINED. For the purpose of this
Indenture, the following events are hereby defined as, and are declared to be,

                  (a)      default in the due and punctual payment of any
         interest on any Note when the same becomes due and payable, and such
         default shall continue for a period of five (5) days;

                  (b)      default in the due and punctual payment of the
         principal of any Note when the same becomes due and payable on the

                  (c)      default in the performance or observance of any other
         of the covenants, agreements or conditions on the part of the Issuer to

         Notes, and continuation of such default for a period of 90 days after
         written notice thereof by the Trustee to the Issuer; and

<PAGE>

                  (d)      the occurrence of an Event of Bankruptcy.

         Any notice herein provided to be given to the Issuer with respect to
any default shall be deemed sufficiently given if sent by registered mail with
postage prepaid to the Person to be notified, addressed to such Person at the
post office address as shown in Section 9.01 of this Indenture or such other
address as may hereafter be given as the principal office of the Issuer in
writing to the Trustee by an Authorized Representative of the Issuer. The
Trustee may give any such notice in its discretion and shall give such notice if
requested to do so in writing by the Registered Owners of at least 51% of the
collective aggregate principal amount of the Highest Priority Obligations at the
time Outstanding.

         SECTION 6.02. REMEDY ON DEFAULT; POSSESSION OF TRUST ESTATE. Subject to
Sections 7.05, 7.07 and 6.08 hereof, upon the happening and continuance of any
Event of Default, the Trustee or by its attorneys or agents may enter into and
upon and take possession of such portion of the Trust Estate as shall be in the
custody of others, and all property comprising the Trust Estate, and each and
every part thereof, and exclude the Issuer and its agents, servants and
employees wholly therefrom, and have, hold, use, operate, manage, and control
the same and each and every part thereof, and in the name of the Issuer or
otherwise, as they shall deem best, conduct the business thereof and exercise
the privileges pertaining thereto and all the rights and powers of the Issuer
and use all of the then existing Trust Estate for that purpose, and collect and
receive all charges, income and Available Funds of the same and of every part
thereof, and after deducting therefrom all expenses incurred hereunder and all
other proper outlays herein authorized, and all payments which may be made as
just and reasonable compensation for its own services, and for the services of
its attorneys, agents, and assistants, the Trustee shall apply the rest and
residue of the money received by the Trustee as follows:

                  FIRST, to the Trustee and the Delaware Trustee, any Trustee
         Fee and any Delaware Trustee Fee, respectively due and owing;

                  SECOND, to the Servicer for due and unpaid 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 ratably, without preference or
         priority of any kind, according to the amounts due and payable on the
         Notes for such 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

                                       47

<PAGE>

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

         The Trustee may fix a record date and payment date for any payment to
Registered Owners pursuant to this Section 6.02. At least 15 days before such
record date, the Trustee shall mail to each Registered Owner and the Issuer a
notice that states the record date, the payment date and the amount to be paid.

         SECTION 6.03. REMEDIES ON DEFAULT; ADVICE OF COUNSEL. Upon the
happening of any Event of Default, the Trustee may proceed to protect and
enforce the rights of the Trustee and the Registered Owners in such manner as
counsel for the Trustee may advise, whether for the specific performance of any
covenant, condition, agreement or undertaking herein contained, or in aid of the
execution of any power herein granted, or for the enforcement of such other
appropriate legal or equitable remedies as, in the opinion of such counsel, may
be more effectual to protect and enforce the rights aforesaid.

         SECTION 6.04. REMEDIES ON DEFAULT; SALE OF TRUST ESTATE. Upon the
happening of any Event of Default and if the principal of all of the Outstanding
Obligations shall have been declared due and payable, then and in every such
case, and irrespective of whether other remedies authorized shall have been
pursued in whole or in part, the Trustee may sell, with or without entry, to the
highest bidder the Trust Estate, and all right, title, interest, claim and
demand thereto and the right of redemption thereof, at any such place or places,
and at such time or times and upon such notice and terms as may be required by
law. Upon such sale the Trustee may make and deliver to the purchaser or
purchasers a good and sufficient assignment or conveyance for the same, which
sale shall be a perpetual bar both at law and in equity against the Issuer and
all Persons claiming such properties. No purchaser at any sale shall be bound to
see to the application of the purchase money or to inquire as to the
authorization, necessity, expediency or regularity of any such sale. The Trustee
is hereby irrevocably appointed the true and lawful attorney-in-fact of the
Issuer, in its name and stead, to make and execute all bills of sale,
instruments of assignment and transfer and such other documents of transfer as
may be necessary or advisable in connection with a sale of all or part of the
Trust Estate, but the Issuer, if so requested by the Trustee, shall ratify and
confirm any sale or sales by executing and delivering to the Trustee or to such
purchaser or purchasers all such instruments as may be necessary, or in the
judgment of the Trustee, proper for the purpose which may be designated in such
request. In addition, the Trustee may proceed to protect and enforce the rights
of the Trustee and the Registered Owners of the Obligations in such manner as
counsel for the Trustee may advise, whether for the specific performance of any
covenant, condition, agreement or undertaking herein contained, or in aid of the
execution of any power herein granted, or for the enforcement of such other
appropriate legal or equitable remedies as may in the opinion of such counsel,
be more effectual to protect and enforce the rights aforesaid. The Trustee shall
take any such action or actions if requested to do so in writing by the
Registered Owners of at least 51% of the collective aggregate principal amount
of the Highest Priority Obligations at the time Outstanding.

         SECTION 6.05. APPOINTMENT OF RECEIVER. In case an Event of Default
occurs, and if all of the Outstanding Obligations shall have been declared due
and payable and in case any judicial proceedings are commenced to enforce any
right of the Trustee or of the Registered Owners

                                       48

<PAGE>

under this Indenture or otherwise, then as a matter of right, the Trustee shall
be entitled to the appointment of a receiver of the Trust Estate and of the
earnings, income or revenue, rents, issues and profits thereof with such powers
as the court making such appointments may confer.

         SECTION 6.06. RESTORATION OF POSITION. In case the Trustee shall have
proceeded to enforce any rights under this Indenture by sale or otherwise, and
such proceedings shall have been discontinued, or shall have been determined
adversely to the Trustee, then and in every such case to the extent not
inconsistent with such adverse decree, the Issuer, the Trustee and the
Registered Owners shall be restored to their former respective positions and the
rights hereunder in respect to the Trust Estate, and all rights, remedies and
powers of the Trustee and of the Registered Owners shall continue as though no
such proceeding had been taken.

         SECTION 6.07. APPLICATION OF SALE PROCEEDS. The proceeds of any sale of
the Trust Estate, together with any funds at the time held by the Trustee and
not otherwise appropriated, shall be applied by the Trustee as set forth in
Section 6.02 hereof, and then to the Issuer or whomsoever shall be lawfully
entitled thereto.

         SECTION 6.08. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT. If an
Event of Default should occur and be continuing, then and in every such case the
Trustee or the Registered Owners of Obligations representing not less than a
majority of the Outstanding Amount of the Highest Priority Obligations may
declare all the Obligations to be immediately due and payable, by a notice in
writing to the Issuer (and to the Trustee if given by Registered Owners), and
upon any such declaration the unpaid principal amount of such Obligations,
together with accrued and unpaid interest thereon through the date of
acceleration, shall become immediately due and payable, subject, however, to
Section 6.04 of this Indenture.

         At any time after such declaration of acceleration of maturity has been
made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article VI provided, the
Registered Owners of Obligations representing a majority of the collective
aggregate principal amount of the Highest Priority Obligations then Outstanding,
by written notice to the Issuer and the Trustee, may rescind and annul such
declaration and its consequences if:

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

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

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

                  (b)      all Events of Default, other than the nonpayment of
         the principal of the Obligations that has become due solely by such
         acceleration, have been cured or waived as provided in Section 6.14
         hereof.

                                       49

<PAGE>

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

         SECTION 6.09. REMEDIES NOT EXCLUSIVE. The remedies herein conferred
upon or reserved to the Trustee or the Registered Owners of Obligations are not
intended to be exclusive of any other remedy, but each remedy herein provided
shall be cumulative and shall be in addition to every other remedy given
hereunder or now or hereafter existing, and every power and remedy hereby given
to the Trustee or to the Registered Owners of Obligations, or any supplement
hereto, may be exercised from time to time as often as may be deemed expedient.
No delay or omission of the Trustee or of any Registered Owner of Obligations to
exercise any power or right arising from any default hereunder shall impair any
such right or power or shall be construed to be a waiver of any such default or
to be acquiescence therein.

         SECTION 6.10. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
TRUSTEE. The Issuer covenants that if:

                  (a)      default is made in the payment of any installment of
         interest, if any, on any Notes when such interest becomes due and
         payable and such default continues for a period of five (5) days; or

                  (b)      default is made in the payment of the principal of
         (or premium, if any, on) any Notes at its Note Final Maturity Date,

then the Issuer will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Registered Owners, the whole amount then due and payable on such
Notes for principal (and premium, if any) and interest, with interest upon any
overdue principal (and premium, if any) and, to the extent that payment of such
interest shall be legally enforceable, upon any overdue installments of
interest, if any, at the rate or rates borne by or provided for in such Notes,
and, in addition thereto, such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
fees, expenses, disbursements and advances of the Trustee and its agents and
counsel.

         If the Issuer fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as Trustee of an express trust, may upon receiving
indemnification satisfactory to the Trustee institute a judicial proceeding for
the collection of the sums so due and unpaid, may prosecute such proceeding to
judgment or final decree, and may enforce the same against the Issuer or any
other obligor upon such Notes of such series and collect the moneys adjudged or
decreed to be payable in the manner provided by law out of the property of the
Issuer or any other obligor upon such Notes, wherever situated.

         If an Event of Default with respect to Notes occurs and is continuing,
the Trustee may, after being indemnified to its satisfaction and in its
discretion, proceed to protect and enforce its rights and the rights of the
Registered Owners of Notes and any related coupons by such appropriate judicial
proceedings as the Trustee shall deem most effectual 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.

                                       50

         SECTION 6.11. DIRECTION OF TRUSTEE. Upon the happening of any Event of
Default, the Registered Owners of at least 51% of the collective aggregate
principal amount of the Highest Priority Obligations then Outstanding, shall
have the right by an instrument or instruments in writing delivered to the
Trustee to direct and control the Trustee as to the method of taking any and all
proceedings for any sale of any or all of the Trust Estate, or for the
appointment of a receiver, if permitted by law, and may at any time cause any
proceedings authorized by the terms hereof to be so taken or to be discontinued
or delayed; provided, however, that such Registered Owners shall not be entitled
to cause the Trustee to take any proceedings which in the Trustee's opinion
would be unjustly prejudicial to non-assenting Registered Owners of Obligations,
but the Trustee shall be entitled to assume that the action requested by the
Registered Owners of at least 51% of the collective aggregate principal amount
of the Highest Priority Obligations then Outstanding will not be prejudicial to
any non-assenting Registered Owners unless the Registered Owners of more than
50% of the collective aggregate principal amount of the non-assenting Registered
Owners of such Obligations, in writing, show the Trustee how they will be
prejudiced. Provided, however, that anything in this Indenture to the contrary
notwithstanding, the Registered Owners of a majority of the collective aggregate
principal amount of the Highest Priority Obligations then Outstanding together
with the Registered Owners of a majority of the collective aggregate principal
amount of all other Obligations then Outstanding shall have the right, at any
time, by an instrument or instruments in writing executed and delivered to the
Trustee, to direct the method and place of conducting all proceedings to be
taken in connection with the enforcement of the terms and conditions of this
Indenture, or for the appointment of a receiver or any other proceedings
hereunder, provided that such direction shall not be otherwise than in
accordance with the provisions of law and of this Indenture. The provisions of
this Section 6.11 shall be expressly subject to the provisions of Sections
7.01(c), 7.05 and 7.07 hereof.

         SECTION 6.12. RIGHT TO ENFORCE IN TRUSTEE. No Registered Owner of any
Obligation shall have any right as such Registered Owner to institute any suit,
action or proceedings for the enforcement of the provisions of this Indenture or
for the execution of any trust hereunder or for the appointment of a receiver or
for any other remedy hereunder, all rights of action hereunder being vested
exclusively in the Trustee, unless and until such Registered Owner shall have
previously given to the Trustee written notice of a default hereunder, and of
the continuance thereof, and also unless the Registered Owners of the requisite
principal amount of the Obligations then Outstanding shall have made written
request upon the Trustee and the Trustee shall have been afforded reasonable
opportunity to institute such action, suit or proceeding in its own name, and
unless the Trustee shall have been offered indemnity and security satisfactory
to it against the costs, expenses and liabilities to be incurred therein or
thereby, which offer of indemnity shall be an express condition precedent
hereunder to any obligation of the Trustee to take any such action hereunder,
and the Trustee for 30 days after receipt of such notification, request and
offer of indemnity, shall have failed to institute any such action, suit or
proceeding. It is understood and intended that no one or more Registered Owners
of the Obligations shall have the right in any manner whatever by his or their
action to affect, disturb or prejudice the lien of this Indenture or to enforce
any right hereunder except in the manner herein provided and for the equal
benefit of the Registered Owners of not less than a majority of the collective
aggregate principal amount of the Obligations then Outstanding.

                                       51

<PAGE>

         SECTION 6.13. PHYSICAL POSSESSION OF OBLIGATIONS NOT REQUIRED. In any
suit or action by the Trustee arising under this Indenture or on all or any of
the Obligations issued hereunder, or any supplement hereto, the Trustee shall
not be required to produce such Obligations, but shall be entitled in all things
to maintain such suit or action without their production.

         SECTION 6.14. WAIVERS OF EVENTS OF DEFAULT. The Trustee may in its
discretion waive any Event of Default hereunder and its consequences and rescind
any declaration of acceleration of Obligations, and shall do so upon the written
request of the Registered Owners of at least a majority of the collective
aggregate principal amount of the Highest Priority Obligations then Outstanding;
provided, however, that there shall not be waived (a) any Event of Default in
the payment of the principal of or premium on any Outstanding Obligations at the
date of maturity thereof, or any default in the payment when due of the interest
on any such Obligations, unless prior to such waiver or rescission, all arrears
of interest or all arrears of payments of principal and all expenses of the
Trustee, in connection with such default shall have been paid or provided for;
or (b) any default in the payment of amounts set forth in Sections 7.05 and 7.07
hereof. In case of any such waiver or rescission, or in case any proceedings
taken by the Trustee on account of any such default shall have been discontinued
or abandoned or determined adversely to the Trustee, then and in every such case
the Issuer, the Trustee and the Registered Owners of Obligations shall be
restored to their former positions and rights hereunder respectively, but no
such waiver or rescission shall extend to or affect any subsequent or other
default, or impair any rights or remedies consequent thereon. The Trustee shall
give written notice to the Rating Agency of any waiver of an Event of Default
pursuant to this Section 6.14.

                                  ARTICLE VII

                                  THE TRUSTEE

         SECTION 7.01. ACCEPTANCE OF TRUST. The Trustee hereby accepts the
trusts imposed upon it by this Indenture, and agrees to perform said trusts, but
only upon and subject to the following terms and conditions:

                  (a)      Except during the continuance of an Event of Default,

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

                           (ii)     in the absence of bad faith on its part, the
                  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
                  Trustee and conforming to the requirements of this Indenture;
                  but in the case of any such certificates or opinions which by
                  any provisions hereof are specifically required to be
                  furnished to the Trustee, the Trustee shall be under a duty to
                  examine the same to determine whether or not they conform as
                  to form with the requirements of this Indenture and whether or
                  not they contain the statements required under this Indenture.

                                       52

<PAGE>

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

                  (c)      Before taking any action hereunder requested by
         Registered Owners, the Trustee may require that it be furnished an
         indemnity bond or other indemnity and security satisfactory to it by
         the Registered Owners, as applicable, for the reimbursement of all
         expenses to which it may be put and to protect it against all
         liability.

         SECTION 7.02. RECITALS OF OTHERS. The recitals, statements and
representations set forth herein and in the Notes shall be taken as the
statements of the Issuer, and the Trustee assumes no responsibility for the
correctness of the same. The Trustee makes no representations as to the title of
the Issuer in the Trust Estate or as to the security afforded thereby and
hereby, or as to the validity or sufficiency of this Indenture or of the Notes
issued hereunder, and the Trustee shall incur no responsibility in respect of
such matters.

         SECTION 7.03. AS TO FILING OF INDENTURE. The Trustee shall be under no
duty (a) to file or record, or cause to be filed or recorded, this Indenture or
any instrument supplemental hereto, (b) or to procure any further order or
additional instruments of further assurance, (c) to see to the delivery to it of
any personal property intended to be mortgaged or pledged hereunder or
thereunder, (d) or to do any act which may be suitable to be done for the better
maintenance of the lien or security hereof (other than the filing of any
continuation (but not initial) statements), or (e) for giving notice of the
existence of such lien, or for extending or supplementing the same or to see
that any rights to the Trust Estate and Funds intended now or hereafter to be
transferred in trust hereunder are subject to the lien hereof. The Trustee shall
not be liable for failure of the Issuer to pay any tax or taxes in respect of
such property, or any part thereof, or the income therefrom or otherwise, nor
shall the Trustee be under any duty in respect of any tax which may be assessed
against it or the Registered Owners in respect of such property or pledged to
the Trust Estate. The Trustee agrees to prepare, request that the Issuer execute
(if such execution is necessary for any such filing) and file in a timely manner
(if received from the Issuer in a timely manner) with any necessary execution by
the Issuer, the continuation statements referred to herein; provided, that the
Trustee shall have no responsibility for the sufficiency, adequacy or priority
of any initial filing and in the absence of written notice to the contrary by
the Issuer or other Authorized Representative, may rely and shall be protected
in relying on all information and exhibits in such initial filings for the
purposes of any continuation statements.

         SECTION 7.04. TRUSTEE MAY ACT THROUGH AGENTS. The Trustee may execute
any of the trusts or powers hereof and perform any duty hereunder, either itself
or by or through its attorneys, agents or employees, and it shall not be
answerable or accountable for any default, neglect or misconduct of any such
attorneys, agents or employees, if reasonable care has been exercised in the
appointment, supervision and monitoring of the work performed. All reasonable
costs incurred by the Trustee and all reasonable compensation to all such
persons as may reasonably be employed in connection with the trusts hereof shall
be paid by the Issuer.

         SECTION 7.05. INDEMNIFICATION OF TRUSTEE. Other than with respect to

the remedy of acceleration as

provided in Sections 6.02 and 6.08 hereof, for each of which no additional
security or indemnity may be required, the Trustee shall be under no obligation
or duty to perform any act at the request of Registered Owners or to institute
or defend any suit in respect thereof unless properly indemnified and provided
with security to its satisfaction as provided in Section 7.01(c) hereof. The
Trustee shall not be required to take notice, or be deemed to have knowledge, of
any default or Event of Default of the Issuer hereunder and may conclusively
assume that there has been no such default or Event of Default (other than an
Event of Default described in Section 6.01(a) or (b) hereof) unless and until it
shall have been specifically notified in writing at the address in Section 9.01
hereof of such default or Event of Default by (a) the Registered Owners of the
required percentages in principal amount of the Obligations then Outstanding
hereinabove specified or (b) an Authorized Representative of the Issuer.
However, the Trustee may begin suit, or appear in and defend suit, execute any
of the trusts hereby created, enforce any of its rights or powers hereunder, or
do anything else in its judgment proper to be done by it as Trustee, without
assurance of reimbursement or indemnity, and in such case the Trustee shall be
reimbursed or indemnified by the Registered Owners requesting such action, if
any, or the Issuer in all other cases, for all fees, costs and expenses,
liabilities, outlays and counsel fees and other reasonable disbursements
properly incurred in connection therewith, unless such costs and expenses,
liabilities, outlays and attorneys' fees and other reasonable disbursements
properly incurred in connection therewith are adjudicated to have resulted from
the negligence or willful misconduct of the Trustee. In furtherance and not in
limitation of this Section 7.05, the Trustee shall not be liable for, and shall
be held harmless by the Issuer from, following any Issuer Orders, instructions
or other directions upon which the Trustee is authorized to rely pursuant to
this Indenture or any other agreement to which it is a party. If the Issuer or
the Registered Owners, as appropriate, shall fail to make such reimbursement or
indemnification, the Trustee may reimburse itself from any money in its
possession under the provisions of this Indenture, subject only to the prior
lien of the Notes for the payment of the principal thereof, premium, if any, and
interest thereon from the Collection Fund. None of the provisions contained in
this Indenture or any other Agreement to which it is a party shall require the
Trustee to act or to expend or risk its own funds or otherwise incur individual
financial liability in the performance of any of its duties or in the exercise
of any of its rights or powers if the Registered Owners shall not have offered
security and indemnity acceptable to it or if it shall have reasonable grounds
for believing that prompt repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it.

         The Issuer agrees to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expenses incurred without negligence or bad
faith on its part, arising out of or in connection with the acceptance or
administration of the trust or trusts hereunder, including the costs and
expenses of defending itself against any claim or liability in connection with
the exercise or performance of any of its powers or duties hereunder arising
from the Trust Estate. The Issuer agrees to indemnify and hold harmless the
Trustee against any and all claims, demands, suits, actions or other proceedings
and all liabilities, costs and expenses whatsoever caused by any untrue
statement or misleading statement or alleged untrue statement or alleged
misleading statement of a material fact contained in any offering document
distributed in connection with the issuance of the Notes or caused by any
omission or alleged omission from such offering document of any material fact
required to be stated therein or necessary in order to make the statements made
therein in the light of the circumstances under which they were made, not
misleading.

         SECTION 7.06. TRUSTEE'S RIGHT TO RELIANCE. The Trustee shall be
protected in acting upon any notice, resolution, request, consent, order,
certificate, report, appraisal, opinion, report or document of the Issuer or the
Servicer or other paper or document believed by it to be genuine and to have
been signed or presented by the proper party or parties. The Trustee may consult
with experts and with counsel (who may but need not be counsel for the Issuer,
the Trustee, or for a Registered Owner), and the opinion of such counsel shall
be full and complete authorization and protection in respect of any action taken
or suffered, and in respect of any determination made by it hereunder in good
faith and in accordance with the opinion of such counsel.

         Whenever in the administration hereof the Trustee shall reasonably deem
it desirable that a matter be proved or established prior to taking, suffering
or omitting any action hereunder, the Trustee (unless other evidence be herein
specifically prescribed) may, in the absence of bad faith on its part, rely upon
a certificate signed by an Authorized Representative of the Issuer or an
authorized officer of the Administrator or the Servicer.

         The Trustee shall not be liable for any action taken, suffered or
omitted by it in good faith and believed by it to be authorized or within the
discretion or rights or powers conferred upon it hereby; provided, however, that
the Trustee shall be liable for its negligence or willful misconduct in taking
such action.

         The Trustee is authorized to enter into agreements with other Persons,
in its capacity as Trustee, in order to carry out or implement the terms and
provisions of this Indenture. The Trustee shall not be liable with respect to
any action taken, suffered or omitted to be taken in good faith in accordance
with this Indenture or any other transaction document or at the direction of the
Registered Owners evidencing the appropriate percentage of the aggregate
principal amount of the Outstanding Notes relating to the time, method and place
of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred upon the Trustee, under this Indenture
or any other transaction document.

         SECTION 7.07. COMPENSATION OF TRUSTEE. Except as otherwise expressly
provided herein, all advances, counsel fees (including without limitation
allocated fees of in-house counsel) and other expenses reasonably made or
incurred by the Trustee in and about the execution and administration of the
trust hereby created and reasonable compensation to the Trustee for its services
in the premises shall be paid by the Issuer. The compensation of the Trustee
shall not be limited to or by any provision of law in regard to the compensation
of trustees of an express trust. The Trustee shall not change the amount of its
annual compensation without giving the Issuer and the Rating Agency at least 90
days' written notice prior to the beginning of a Fiscal Year. If not paid by the
Issuer, the Trustee shall have a lien against all money held pursuant to this
Indenture, subject only to the prior lien of the Obligations against the money
and investments in the Collection Fund for the payment of the principal thereof,
premium, if any, and interest thereon, for such reasonable compensation,
expenses, advances and counsel fees incurred in and about the execution of the
trusts hereby created and the exercise and performance of the powers and duties
of the Trustee hereunder and the cost and expense incurred in defending against
any liability in the premises of any character whatsoever (unless such liability
is adjudicated to have resulted from the negligence or willful misconduct of the
Trustee).

<PAGE>

         SECTION 7.08. TRUSTEE MAY OWN NOTES. The Trustee shall comply with TIA
Section 311(a), excluding any creditor relationship listed in TIA Section
311(b). A Trustee who has resigned or been removed shall be subject to TIA
Section 311(a) to the extent indicated therein. The Trustee hereunder, or any
successor Trustee, in its individual or other capacity, may become the owner or
pledgee of Notes and may otherwise deal with the Issuer, with the same rights it
would have if it were not the Trustee. The Trustee may act as depository for,
and permit any of its officers or directors to act as a member of, or act in any
other capacity in respect to, any committee formed to protect the rights of the
Registered Owners or to effect or aid in any reorganization growing out of the
enforcement of the Notes or of this Indenture, whether or not any such committee
shall represent the Registered Owners of more than 60% of the collective
aggregate principal amount of the Outstanding Obligations.

         SECTION 7.09. RESIGNATION OF TRUSTEE. The Trustee and any successor to
the Trustee may resign and be discharged from the trust created by this
Indenture by giving to the Issuer notice in writing which notice shall specify
the date on which such resignation is to take effect; provided, however, that
such resignation shall only take effect on the day specified in such notice if a
successor Trustee shall have been appointed pursuant to Section 7.11 hereof (and
is qualified to be the Trustee under the requirements of Section 7.11 hereof).
If no successor Trustee has been appointed by the date specified or within a
period of 90 days from the receipt of the notice by the Issuer, whichever period
is the longer, the Trustee may (a) appoint a temporary successor Trustee having
the qualifications provided in Section 7.11 hereof or (b) request a court of
competent jurisdiction to (i) require the Issuer to appoint a successor, as
provided in Section 7.11 hereof, within three days of the receipt of citation or
notice by the court, or (ii) appoint a Trustee having the qualifications
provided in Section 7.11 hereof. In no event may the resignation of the Trustee
be effective until a qualified successor Trustee shall have been selected and
appointed. In the event a temporary successor Trustee is appointed pursuant to
(a) above, the Issuer may remove such temporary successor Trustee and appoint a
successor thereto pursuant to Section 7.11 hereof.

         SECTION 7.10. REMOVAL OF TRUSTEE. The Trustee or any successor Trustee
may be removed (a) at any time by the Registered Owners of a majority of the
collective aggregate principal amount of the Highest Priority Obligations then
Outstanding, (b) by the Issuer for cause or upon the sale or other disposition
of the Trustee or its corporate trust functions or (c) by the Issuer without
cause so long as no Event of Default exists or has existed within the last 30
days, upon payment to the Trustee so removed of all money then due to it
hereunder and appointment of a successor thereto by the Issuer and acceptance
thereof by said successor. One copy of any such order of removal shall be filed
with the Delaware Trustee and the other with the Trustee so removed.

         In the event a Trustee (or successor Trustee) is removed, by any person
or for any reason permitted hereunder, such removal shall not become effective
until (a) in the case of removal by the Registered Owners, such Registered
Owners by instrument or concurrent instruments in writing (signed and
acknowledged by such Registered Owners or their attorneys-in-fact) filed with
the Trustee removed have appointed a successor Trustee or otherwise the Issuer
shall have appointed a successor, and (b) the successor Trustee has accepted
appointment as such.

<PAGE>

         SECTION 7.11. SUCCESSOR TRUSTEE. In case at any time the Trustee or any
successor Trustee shall resign, be dissolved, or otherwise shall be disqualified
to act or be incapable of acting, or in case control of the Trustee or of any
successor Trustee or of its officers shall be taken over by any public officer
or officers, a successor Trustee may be appointed by the Issuer by an instrument
in writing duly authorized by the Issuer. In the case of any such appointment by
the Issuer of a successor to the Trustee, the Issuer shall forthwith cause
notice thereof to be mailed to the Registered Owners of the Notes at the address
of each Registered Owner appearing on the note registration books maintained by
the Registrar.

         Every successor Trustee appointed by the Registered Owners, by a court
of competent jurisdiction, or by the Issuer shall be a bank or trust company in
good standing, organized and doing business under the laws of the United States
or of a state therein, which has a reported capital and surplus of not less than
$50,000,000, be authorized under the law to exercise corporate trust powers, be
subject to supervision or examination by a federal or state authority, and be an
Eligible Lender so long as such designation is necessary to maintain guarantees
and federal benefits under the Act with respect to the Financed Eligible Loans
originated under the Act.

         SECTION 7.12. MANNER OF VESTING TITLE IN TRUSTEE. Any successor Trustee
appointed hereunder shall execute, acknowledge and deliver to its predecessor
Trustee, and also to the Issuer, an instrument accepting such appointment
hereunder, and thereupon such successor Trustee, without any further act, deed
or conveyance shall become fully vested with all the estate, properties, rights,
powers, trusts, duties and obligations of its predecessors in trust hereunder
(except that the predecessor Trustee shall continue to have the benefits to
indemnification hereunder together with the successor Trustee), with like effect
as if originally named as Trustee herein; but the Trustee ceasing to act shall
nevertheless, on the written request of an Authorized Representative of the
Issuer, or an authorized officer of the successor Trustee, execute, acknowledge
and deliver such instruments of conveyance and further assurance and do such
other things as may reasonably be required for more fully and certainly vesting
and confirming in such successor Trustee all the right, title and interest of
the Trustee which it succeeds, in and to the Trust Estate and such rights,
powers, trusts, duties and obligations, and the Trustee ceasing to act also,
upon like request, pay over, assign and deliver to the successor Trustee any
money or other property or rights subject to the lien of this Indenture,
including any pledged securities which may then be in its possession. Should any
deed or instrument in writing from the Issuer be required by the successor
Trustee for more fully and certainly vesting in and confirming to such new
Trustee such estate, properties, rights, powers and duties, any and all such
deeds and instruments in writing shall on request be executed, acknowledged and
delivered by the Issuer.

         In case any of the Notes to be issued hereunder shall have been
authenticated but not delivered, any successor Trustee may adopt the certificate
of authentication of the Trustee or of any successor to the Trustee; and in case
any of the Notes shall not have been authenticated, any successor to the Trustee
may authenticate such Notes in its own name; and in all such cases such
certificate shall have the full force which it has anywhere in the Notes or in
this Indenture.

         SECTION 7.13. ADDITIONAL COVENANTS BY THE TRUSTEE TO CONFORM TO THE
ACT. The Trustee covenants that it will at all times be an Eligible Lender under
the Act so long as such

                                       57

<PAGE>

designation is necessary, as determined by the Issuer, to maintain the
guarantees and federal benefits under the Act with respect to the Financed
Eligible Loans, that it will acquire Eligible Loans originated under the Act in
its capacity as an Eligible Lender and that it will not knowingly dispose of or
deliver any Financed Eligible Loans originated under the Act or any security
interest in any such Financed Eligible Loans to any party who is not an Eligible
Lender so long as the Act or Regulations adopted thereunder require an Eligible
Lender to be the owner or holder of such Financed Eligible Loans; provided,
however, that nothing above shall prevent the Trustee from delivering the
Eligible Loans to the Servicer or the Guaranty Agency.

         SECTION 7.14. RIGHT OF INSPECTION. A Registered Owner shall be
permitted at reasonable times during regular business hours and in accordance
with reasonable regulations prescribed by the Trustee to examine at the
principal office of the Trustee a copy of any report or instrument theretofore
filed with the Trustee relating to the condition of the Trust Estate.

         SECTION 7.15. LIMITATION WITH RESPECT TO EXAMINATION OF REPORTS. Except
as provided in this Indenture, the Trustee shall be under no duty to examine any
report or statement or other document required or permitted to be filed with it
by the Issuer.

         SECTION 7.16. SERVICING AGREEMENT. The Trustee acknowledges the receipt
of a copy of the Servicing Agreement described in Section 4.04 hereof.

         SECTION 7.17. ADDITIONAL COVENANTS OF TRUSTEE. The Trustee, by the
execution hereof, covenants, represents and agrees that:

                  (a)      it will not exercise any of the rights, duties or
         privileges under this Indenture in such manner as would cause the
         Eligible Loans held or acquired under the terms hereof to be
         transferred, assigned or pledged as security to any person or entity
         other than as permitted by this Indenture; and

                  (b)      it will comply with the Act and the Regulations and
         will, upon written notice from an Authorized Representative of the
         Issuer, the Secretary or the Guaranty Agency, use its reasonable
         efforts to cause this Indenture to be amended (in accordance with
         Section 8.01 hereof) if the Act or Regulations are hereafter amended so
         as to be contrary to the terms of this Indenture.

         SECTION 7.18. DUTY OF TRUSTEE WITH RESPECT TO RATING AGENCIES. It shall
be the duty of the Issuer to notify each Rating Agency then rating any of the
Notes (but the Trustee shall incur no liability for any failure to do so) of (a)
any change, expiration, extension or renewal of this Indenture, (b) prepayment
or defeasance of all the Notes, (c) any change in the Trustee or (d) any other
information reasonably required to be reported to each Rating Agency under any
Supplemental Indenture; provided, however, the provisions of this Section do not
apply when such documents have been previously supplied to such Rating Agency
and the Trustee has received written evidence to such effect, all as may be
required by this Indenture. All notices required to be forwarded to the Rating
Agencies under this Section shall be sent in writing at the following addresses:

         The Trustee also acknowledges that each Rating Agency's periodic review
for maintenance of a Rating on any series of the Notes may involve discussions
and/or meetings with representatives of the Trustee at mutually agreeable times
and places.

         SECTION 7.19. MERGER OF THE TRUSTEE. Any corporation into which the
Trustee may be merged or with which it may be consolidated, or any corporation
resulting from any merger or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, provided such corporation shall be otherwise qualified and eligible
under this Indenture, without the execution or filing of any paper of any
further act on the part of any other parties hereto.

         SECTION 7.20. RECEIPT OF FUNDS FROM SERVICER. The Trustee shall not be
accountable or responsible in any manner whatsoever for any action of the
Issuer, the Administrator, the depository bank of any funds of the Issuer, or
the Servicer while the Servicer is acting as bailee or agent of the Trustee with
respect to the Eligible Loans for actions taken in compliance with any
instruction or direction given to the Trustee, or for the application of funds
or moneys by the Servicer until such time as funds are received by the Trustee.

         SECTION 7.21. SPECIAL CIRCUMSTANCES LEADING TO RESIGNATION OF TRUSTEE.
Because the Trustee serves as trustee hereunder for Obligations of different
priorities, it is possible that circumstances may arise which will cause the
Trustee to resign from its position as trustee for one or more of the
Obligations. In the event that the Trustee makes a determination that it should
so resign, due to the occurrence of an Event of Default or potential default
hereunder, or otherwise, the Issuer may permit such resignation as to one or
more of the Obligations or request the Trustee's resignation as to all
Obligations, as the Issuer may elect. If the Issuer should determine that a
conflict of interest has arisen as to the trusteeship of any of the Obligations,
it may authorize and execute a Supplemental Indenture with one or more successor
Trustees, under which the administration of certain of the Obligations would be
separated from the administration of the other Obligations.

                                       59

<PAGE>

         SECTION 7.22. SURVIVAL OF TRUSTEE'S RIGHTS TO RECEIVE COMPENSATION,
REIMBURSEMENT AND INDEMNIFICATION. The Trustee's rights to receive compensation,
reimbursement and indemnification of money due and owing hereunder at the time
of the Trustee's resignation or removal shall survive the Trustee's resignation
or removal.

         SECTION 7.23. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY; CONFLICTING
INTERESTS. There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined
capital and surplus of at least $50,000,000. If such corporation publishes
reports of condition at least annually, pursuant to law or the requirements of
federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section 7.23, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 7.23, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article VII. Neither the Issuer
nor any Person directly or indirectly controlling or controlled by, or under
common control with, the Issuer shall serve as Trustee.

         SECTION 7.24. TRUSTEE MAY FILE PROOFS OF CLAIM. In case of the pendency
of any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Issuer or any other obligor upon the Notes or the property of the Issuer or
of such other obligor or their creditors, the Trustee (irrespective of whether
the principal of the Notes of any series shall then be due and payable as
therein expressed or by declaration or otherwise and irrespective of whether the
Trustee shall have made any demand on the Issuer for the payment of overdue
principal, premium, if any, or interest) shall be entitled and empowered, by
intervention in such proceeding or otherwise:

                  (a)      to file and prove a claim for the whole amount, or
         such lesser amount as may be provided for in the Notes, of principal
         (and premium, if any) and interest, if any, 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 Trustee
         (including any claim for the reasonable fees, compensation, expenses,
         disbursements and advances of the Trustee and its agents and counsel)
         and of the Registered Owners allowed in such judicial proceeding; and

                  (b)      to collect and receive any money or other property
         payable or deliverable on any such claims and to distribute the same;
         and any custodian, receiver, assignee, trustee, liquidator,
         sequestrator (or other similar official) in any such judicial
         proceeding is hereby authorized by each Registered Owner of Notes to
         make such payments to the Trustee, and if the Trustee shall consent to
         the making of such payments directly to the Registered Owners, to pay
         to the Trustee any amount due to it for the reasonable fees,
         compensation, expenses, disbursements and advances of the Trustee and
         any predecessor Trustee, their agents and counsel, and any other
         amounts due the Trustee or any predecessor Trustee.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Registered Owner of
a Note any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Registered

                                       60

<PAGE>

Owner thereof, or to authorize the Trustee to vote in respect of the claim of
any Registered Owner of a Note in any such proceeding.

         In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party), the Trustee shall be held to represent all the
Registered Owners of the Notes, and it shall not be necessary to make any
Registered Owners of the Notes parties to any such proceedings.

         SECTION 7.25. NO PETITION. The Trustee will not at any time institute
against the Issuer any bankruptcy proceeding under any United States federal or
State bankruptcy or similar law in connection with any obligations of the Issuer
under this Indenture.

                                  ARTICLE VIII

                             SUPPLEMENTAL INDENTURES

         SECTION 8.01. SUPPLEMENTAL INDENTURES NOT REQUIRING CONSENT OF
REGISTERED OWNERS. The Issuer and the Trustee may, without the consent of or
notice to any of the Registered Owners of any Obligations enter into any
indenture or indentures supplemental to this Indenture for any one or more of
the following purposes:

                  (a)      to cure any ambiguity or formal defect or omission in
         this Indenture;

                  (b)      to grant to or confer upon the Trustee for the
         benefit of the Registered Owners any additional benefits, rights,
         remedies, powers or authorities that may lawfully be granted to or
         conferred upon the Registered Owners or the Trustee;

                  (c)      to subject to this Indenture additional revenues,
         properties or collateral;

                  (d)      to modify, amend or supplement this Indenture or any
         indenture supplemental hereto in such manner as to permit the
         qualification hereof and thereof under the Trust Indenture Act of 1939
         or any similar federal statute hereafter in effect or to permit the
         qualification of the Notes for sale under the securities laws of the
         United States of America or of any of the states of the United States
         of America, and, if they so determine, to add to this Indenture or any
         indenture supplemental hereto such other terms, conditions and
         provisions as may be permitted by said Trust Indenture Act of 1939 or
         similar federal statute;

                  (e)      to evidence the appointment of a separate or
         co-Trustee or a co-registrar or transfer agent or the succession of a
         new Trustee hereunder, or any additional or substitute Guaranty Agency
         or Servicer;

                  (f)      to add such provisions to or to amend such provisions
         of this Indenture as may be necessary or desirable to assure
         implementation of the Program in conformance with the Act if along with
         such Supplemental Indenture there is filed an opinion of counsel to the
         effect that the addition or amendment of such provisions will in no way
         impair the existing security of the Registered Owners of any
         Outstanding Obligations;

                                       61

<PAGE>

                  (g)      to make any change as shall be necessary in order to
         obtain and maintain for any of the Notes an investment grade Rating
         from a nationally recognized rating service, which changes, in the
         opinion of the Trustee are not to the prejudice of the Registered Owner
         of any of the Obligations;

                  (h)      to make any changes necessary to comply with the Act,
         the Regulations or the Code and the regulations promulgated thereunder;

                  (i)      to make the terms and provisions of this Indenture,
         including the lien and security interest granted herein, applicable to
         a Derivative Product, and to modify this Indenture with respect to any
         particular Derivative Product;

                  (j)      to create any additional Funds or Accounts or
         Subaccounts under this Indenture deemed by the Trustee to be necessary
         or desirable;

                  (k)      to make any other change with a Rating Confirmation;
         or

                  (l)      to make any other change which, in the judgment of
         the Trustee is not to the material prejudice of the Registered Owners
         of any Obligations;

provided, however, that nothing in this Section shall permit, or be construed as
permitting, any modification of the trusts, powers, rights, duties, remedies,
immunities and privileges of the Trustee without the prior written approval of
the Trustee, which approval shall be evidenced by execution of a Supplemental
Indenture.

         SECTION 8.02. SUPPLEMENTAL INDENTURES REQUIRING CONSENT OF REGISTERED
OWNERS. Exclusive of Supplemental Indentures covered by Section 8.01 hereof and
subject to the terms and provisions contained in this Section, and not
otherwise, the Registered Owners of not less than a majority of the collective
aggregate principal amount of the Obligations then Outstanding shall have the
right, from time to time, to consent to and approve the execution by the Issuer
and the Trustee of such other indenture or indentures supplemental hereto as
shall be deemed necessary and desirable by the Trustee for the purpose of
modifying, altering, amending, adding to or rescinding, in any particular, any
of the terms or provisions contained in this Indenture or in any Supplemental
Indenture; provided, however, that nothing in this Section shall permit, or be
construed as permitting (a) without the consent of the Registered Owners of all
then Outstanding Obligations, (i) an extension of the maturity date of the
principal of or the interest on any Obligation, or (ii) a reduction in the
principal amount of any Obligation or the rate of interest thereon, or (iii) a
privilege or priority of any Obligation or Obligations over any other Obligation
or Obligations except as otherwise provided herein, or (iv) a reduction in the
aggregate principal amount of the Obligations required for consent to such
Supplemental Indenture, or (v) the creation of any lien other than a lien
ratably securing all of the Obligations at any time Outstanding hereunder except
as otherwise provided herein; or (b) any modification of the trusts, powers,
rights, obligations, duties, remedies, immunities and privileges of the Trustee
without the prior written approval of the Trustee.

         If at any time the Issuer shall request the Trustee to enter into any
such Supplemental Indenture for any of the purposes of this Section, the Trustee
shall, upon being satisfactorily indemnified with respect to expenses, cause
notice of the proposed execution of such

                                       62

<PAGE>

Supplemental Indenture to be mailed by registered or certified mail to each
Registered Owner of an Obligation at the address shown on the registration books
or listed in any Derivative Product. Such notice (which shall be prepared by the
Issuer) shall briefly set forth the nature of the proposed Supplemental
Indenture and shall state that copies thereof are on file at the principal
corporate trust office of the Trustee for inspection by all Registered Owners.
If, within 60 days, or such longer period as shall be prescribed by the Issuer,
following the mailing of such notice, the Registered Owners of not less than a
majority of the collective aggregate principal amount of the Obligations
Outstanding at the time of the execution of any such Supplemental Indenture
shall have consented in writing to and approved the execution thereof as herein
provided, no Registered Owner of any Obligation shall have any right to object
to any of the terms and provisions contained therein, or the operation thereof,
or in any manner to question the propriety of the execution thereof, or to
enjoin or restrain the Trustee or the Issuer from executing the same or from
taking any action pursuant to the provisions thereof. Upon the execution of any
such Supplemental Indenture as in this Section 8.02 permitted and provided, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith.

         SECTION 8.03. ADDITIONAL LIMITATION ON MODIFICATION OF INDENTURE. None
of the provisions of this Indenture (including Sections 8.01 and 8.02 hereof)
shall permit an amendment to the provisions of the Indenture which permits the
transfer of all or part of the Financed Eligible Loans originated under the Act
or granting of a security interest therein to any Person other than an Eligible
Lender or the Servicer, unless the Act or Regulations are hereafter modified so
as to permit the same. The Trustee may request an opinion of counsel to the
effect that an amendment or supplement to this Indenture was adopted in
conformance with this Indenture.

         SECTION 8.04. NOTICE OF DEFAULTS. Within 90 days after the occurrence
of any default hereunder with respect to the Notes, the Trustee shall transmit
in the manner and to the extent provided in TIA Section 313(c), notice of such
default hereunder known to the Trustee, unless such default shall have been
cured or waived; provided, however, that, except in the case of a default in the
payment of the principal of (or premium, if any) or interest with respect to any
Note, or in the payment of any sinking fund installment with respect to the
Notes, the Trustee shall be protected in withholding such notice if and so long
as an authorized officer of the Trustee in good faith determine that the
withholding of such notice is in the interest of the Registered Owners of the
Notes. For the purpose of this Section 8.04, the term "default" means any event
which is, or after notice or lapse of time or both would become, an Event of
Default with respect to the Notes.

         SECTION 8.05. CONFORMITY WITH THE TRUST INDENTURE ACT. Every
supplemental indenture executed pursuant to this Article VIII shall conform to
the requirements of the Trust Indenture Act as then in effect.

                                   ARTICLE IX

                               GENERAL PROVISIONS

         SECTION 9.01. NOTICES. Any notice, request or other instrument required
by this Indenture to be signed or executed by the Registered Owners of
Obligations may be executed by

                                       63

<PAGE>

the execution of any number of concurrent instruments of similar tenor, and may
be signed or executed by such Registered Owners of Obligations in person or by
agent appointed in writing. As a condition for acting thereunder the Trustee may
demand proof of the execution of any such instrument and of the fact that any
person claiming to be the owner of any of said Obligations is such owner and may
further require the actual deposit of such Obligation or Obligations with the
Trustee. The fact and date of the execution of such instrument may be proved by
the certificate of any officer in any jurisdiction who by the laws thereof is
authorized to take acknowledgments of deeds within such jurisdiction, that the
person signing such instrument acknowledged before him the execution thereof, or
may be proved by any affidavit of a witness to such execution sworn to before
such officer.

         The amount of Notes held by any person executing such instrument as a
Registered Owner of Notes and the fact, amount and numbers of the Notes held by
such person and the date of his holding the same may be proved by a certificate
executed by any responsible trust company, bank, banker or other depository in a
form approved by the Trustee, showing that at the date therein mentioned such
person had on deposit with such depository the Notes described in such
certificate; provided, however, that at all times the Trustee may require the
actual deposit of such Note or Notes with the Trustee.

shall be in writing (including bank wire, telex, telecopy or facsimile or
similar writing) at the following addresses, and each address shall constitute

         SECTION 9.02. COVENANTS BIND ISSUER. The covenants, agreements,
conditions, promises, and undertakings in this Indenture shall extend to and be
binding upon the successors and assigns of the Issuer, and all of the covenants
hereof shall bind such successors and assigns, and each of them, jointly and
severally. All the covenants, conditions and provisions hereof shall be held to
be for the sole and exclusive benefit of the parties hereto and their successors
and assigns and of the Registered Owners from time to time of the Obligations.

         No extension of time of payment of any of the Obligations shall operate
to release or discharge the Issuer, it being agreed that the liability of the
Issuer, to the extent permitted by law, shall continue until all of the
Obligations are paid in full, notwithstanding any transfer of Financed Eligible
Loans or extension of time for payment.

         SECTION 9.03. LIEN CREATED. This Indenture shall operate effectually as
(a) a grant of lien on and security interest in, and (b) an assignment of, the
Trust Estate.

         SECTION 9.04. SEVERABILITY OF LIEN. If the lien of this Indenture shall
be or shall ever become ineffectual, invalid or unenforceable against any part
of the Trust Estate, which is not subject to the lien, because of want of power
or title in the Issuer, the inclusion of any such part shall not in any way
affect or invalidate the pledge and lien hereof against such part of the Trust
Estate as to which the Issuer in fact had the right to pledge.

         SECTION 9.05. CONSENT OF REGISTERED OWNERS BINDS SUCCESSORS. Any
request or consent of the Registered Owner of any Obligations given for any of
the purposes of this Indenture shall bind all future Registered Owners of the
same Obligation or any Obligations issued in exchange therefor or in
substitution thereof in respect of anything done or suffered by the Issuer or
the Trustee in pursuance of such request or consent.

         SECTION 9.06. NONLIABILITY OF PERSONS; NO GENERAL OBLIGATION. It is
hereby expressly made a condition of this Indenture that any agreements,
covenants or representations herein contained or contained in the Notes do not
and shall never constitute or give rise to a personal or pecuniary liability or
charge against the organizers, officers, employees, agents or trustees or the
Administrator of the Issuer, or against the general credit of the Issuer, and in
the event of a breach of any such agreement, covenant or representation, no
personal or pecuniary liability or

                                       65

<PAGE>

charge payable directly or indirectly from the general revenues of the Issuer
shall arise therefrom. Nothing contained in this Section, however, shall relieve
the Issuer from the observance and performance of the several covenants and
agreements on its part herein contained.

         SECTION 9.07. NONPRESENTMENT OF NOTES OR INTEREST CHECKS. Should any of
the Notes or interest checks not be presented for payment when due, the Trustee
shall retain from any money transferred to it for the purpose of paying the
Notes or interest checks so due, for the benefit of the Registered Owners
thereof, a sum of money sufficient to pay such Notes or interest checks when the
same are presented by the Registered Owners thereof for payment. Such money
shall not be required to be invested. All liability of the Issuer to the
Registered Owners of such Notes or interest checks and all rights of such
Registered Owners against the Issuer under the Notes or interest checks or under
this Indenture shall thereupon cease and determine, and the sole right of such
Registered Owners shall thereafter be against such deposit. If any Note or
interest check shall not be presented for payment within the period of two years
following its payment or prepayment date, the Trustee shall return to the Issuer
the money theretofore held by it for payment of such Note or interest check, and
such Note or interest check shall (subject to the defense of any applicable
statute of limitation) thereafter be an unsecured obligation of the Issuer. The
Trustee's responsibility for any such money shall cease upon remittance thereof
to the Issuer.

         SECTION 9.08. SECURITY AGREEMENT. This Indenture constitutes a
Financing Statement and a Security Agreement under the Delaware Uniform
Commercial Code.

         SECTION 9.09. LAWS GOVERNING. It is the intent of the parties hereto
that this Indenture shall in all respects be governed by the laws of the State
of New York. This Indenture is subject to the provisions of the TIA that are
required to be part of this Indenture and shall, to the extent applicable, be
governed by such provisions.

         SECTION 9.10. SEVERABILITY. Of any covenant, agreement, waiver, or part
thereof in this Indenture contained be forbidden by any pertinent law or under
any pertinent law be effective to render this Indenture invalid or unenforceable
or to impair the lien hereof, then each such covenant, agreement, waiver, or
part thereof shall itself be and is hereby declared to be wholly ineffective,
and this Indenture shall be construed as if the same were not included herein.

         SECTION 9.11. EXHIBITS. The terms of the Schedules and Exhibits, if
any, attached to this Indenture are incorporated herein in all particulars.

         SECTION 9.12. NON-BUSINESS DAYS. Except as may otherwise be provided
herein, if the date for making payment of any amount hereunder or on any Note,
or if the date for taking any action hereunder, is not a Business Day, then such
payment can be made without accruing further interest or action can be taken on
the next succeeding Business Day, with the same force and effect as if such
payment were made when due or action taken on such required date.

         SECTION 9.13. PARTIES INTERESTED HEREIN. Nothing in this Indenture
expressed or implied is intended or shall be construed to confer upon, or to
give to, any person or entity, other than the Trustee, the Delaware Trustee, the
paying agent, if any, and the Registered Owners of

                                       66

<PAGE>

the Obligations, any right, remedy or claim under or by reason of this Indenture
or any covenant, condition or stipulation hereof, and all covenants,
stipulations, promises and agreements in this Indenture contained by and on
behalf of the Issuer shall be for the sole and exclusive benefit of the Trustee,
the paying agent, if any, and the Registered Owners of the Obligations.

         SECTION 9.14. OBLIGATIONS ARE LIMITED OBLIGATIONS. The Notes and the
obligations of the Issuer contained in this Indenture are special, limited
obligations of the Issuer, secured by and payable solely from the Trust Estate
herein provided. The Issuer shall not be obligated to pay the Notes, the
interest thereon, or any other obligation created by or arising from this
Indenture from any other source.

         SECTION 9.15. COUNTERPARTY RIGHTS. No Counterparty which shall be in
default under any Derivative Product with the Issuer shall have any of the
rights granted to a Counterparty or as the Registered Owner of an Obligation
hereunder. A Counterparty which is in default under any Derivative Product shall
however, continue to maintain all obligations undertaken by it under the terms
of its Derivative Product.

         SECTION 9.16. DISCLOSURE OF NAMES AND ADDRESSES OF REGISTERED OWNERS.
Registered Owners of Notes, by receiving and holding the same, agree with the
Issuer and the Trustee that neither the Issuer nor the Trustee nor any
Securities Depository shall be held accountable by reason of the disclosure of
any information as to the names and addresses of the Registered Owners of Notes
in accordance with TIA Section 312, regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under TIA Section
312(b).

         SECTION 9.17. AGGREGATE PRINCIPAL AMOUNT OF OBLIGATIONS. Whenever in
this Indenture reference is made to the aggregate principal amount of any
Obligations, such phrase shall mean, at any time, the principal amount of any
Notes.

         SECTION 9.18. FINANCED ELIGIBLE LOANS. The Issuer expects to acquire
Eligible Loans and to transfer Eligible Loans to the Trustee, in accordance with
this Indenture, which Eligible Loans, upon becoming subject to the lien of this
Indenture, constitute Financed Eligible Loans, as defined herein. If for any
reason a Financed Eligible Loan does not constitute an Eligible Loan, or ceases
to constitute an Eligible Loan, such loan shall continue to be subject to the
lien of this Indenture as a Financed Eligible Loan.

         SECTION 9.19. CONCERNING THE DELAWARE TRUSTEE. It is expressly
understood and agreed by the parties to this Indenture and the Registered Owners
that (a) this Indenture is executed and delivered by the Delaware Trustee not in
its individual or personal capacity but solely in its capacity as Delaware
Trustee under the Trust Agreement on behalf of the Issuer, in the exercise of
the powers and authority conferred and vested in it as Delaware Trustee under
the Trust Agreement, subject to the protections, indemnities and limitations
from liability afforded to the Delaware Trustee thereunder; (b) the
representations, warranties, covenants, undertakings, agreements and obligations
by the Delaware Trustee are made and intended not as personal representations,
warranties, covenants, undertakings, agreements and obligations by Wilmington
Trust Company, but are made and intended for the purpose of only binding the
Trust Estate, as defined in the Trust Agreement, and the Issuer; (c) nothing
contained herein shall be construed as

                                       67

<PAGE>

creating any liability on Wilmington Trust Company, individually or personally,
to perform any expressed or implied covenant, duty or obligation of any kind
whatsoever contained herein; and (d) under no circumstances shall Wilmington
Trust Company, be personally liable for the payment of any fees, costs,
indebtedness or expenses of any kind whatsoever or be personally liable for the
breach or failure of any obligation, representation, agreement, warranty or
covenant whatsoever made or undertaken by the Delaware Trustee or Issuer
hereunder.

                                    ARTICLE X

                        PAYMENT AND CANCELLATION OF NOTES
                          AND SATISFACTION OF INDENTURE

         SECTION 10.01. TRUST IRREVOCABLE. The trust created by the terms and
provisions of this Indenture is irrevocable until the indebtedness secured
hereby (the Notes and interest thereon) and all Issuer Derivative Payments are
fully paid or provision made for its payment as provided in this Article.

         SECTION 10.02. SATISFACTION OF INDENTURE.

                  (a)      If the Issuer shall pay, or cause to be paid, or
         there shall otherwise be paid (i) to the Registered Owners of the
         Notes, the principal of and interest on the Notes, at the times and in
         the manner stipulated in this Indenture; and (ii) to each Counterparty,
         all Issuer Derivative Payments then due, then the pledge of the Trust
         Estate which is not pledged hereunder, and all covenants, agreements
         and other obligations of the Issuer to the Registered Owners of Notes
         shall thereupon cease, terminate and become void and be discharged and
         satisfied. In such event, the Trustee shall execute and deliver to the
         Issuer all such instruments as may be desirable to evidence such
         discharge and satisfaction, and the Trustee shall pay over or deliver
         all money held by it under this Indenture to the party entitled to
         receive the same under this Indenture. If the Issuer shall pay or cause
         to be paid, or there shall otherwise be paid, to the Registered Owners
         of any Outstanding Notes the principal of and interest on such Notes
         and to each Counterparty all Counterparty Payments then due, at the
         times and in the manner stipulated in this Indenture and in the
         Derivative Product, such Notes and each Counterparty shall cease to be
         entitled to any lien, benefit or security under this Indenture, and all
         covenants, agreements and obligations of the Issuer to the Registered
         Owners thereof and each Counterparty shall thereupon cease, terminate
         and become void and be discharged and satisfied.

                  (b)      Notes or interest installments shall be deemed to
         have been paid within the meaning of Section 10.02(a) hereof if money
         for the payment thereof has been set aside and is being held in trust
         by the Trustee at the Note Final Maturity Date or earlier prepayment
         date thereof. Any Outstanding Note shall, prior to the Note Final
         Maturity Date or earlier prepayment thereof, be deemed to have been
         paid within the meaning and with the effect expressed in Section
         10.02(a) hereof if (i) such Note is to be prepaid on any date prior to
         its Note Final Maturity Date and (ii) the Issuer shall have given
         notice of prepayment as provided herein on said date, there shall have
         been deposited with the Trustee either money (fully insured by the
         Federal Deposit Insurance Issuer or fully collateralized by
         Governmental Obligations) in an amount which shall be sufficient, or

                                       68

<PAGE>

         Governmental Obligations (including any Governmental Obligations issued
         or held in book-entry form on the books of the Department of Treasury
         of the United States of America) the principal of and the interest on
         which when due will provide money which, together with the money, if
         any, deposited with the Trustee at the same time, shall be sufficient,
         to pay when due the principal of and interest to become due on such
         Note on and prior to the prepayment date or Note Final Maturity Date
         thereof, as the case may be. Notwithstanding anything herein to the
         contrary, however, no such deposit shall have the effect specified in
         this subsection (b) if made during the existence of an Event of
         Default, unless made with respect to all of the Notes then Outstanding.
         Neither Governmental Obligations nor money deposited with the Trustee
         pursuant to this subsection (b) nor principal or interest payments on
         any such Governmental Obligations shall be withdrawn or used for any
         purpose other than, and shall be held irrevocably in trust in an escrow
         account for, the payment of the principal of and interest on such
         Notes. Any cash received from such principal of and interest on such
         Governmental Obligations deposited with the Trustee, if not needed for
         such purpose, shall, to the extent practicable, be reinvested in
         Governmental Obligations maturing at times and in amounts sufficient to
         pay when due the principal of and interest on such Notes on and prior
         to such prepayment date or Note Final Maturity Date thereof, as the
         case may be, and interest earned from such reinvestments shall be paid
         over to the Issuer, as received by the Trustee, free and clear of any
         trust, lien or pledge. Any payment for Governmental Obligations
         purchased for the purpose of reinvesting cash as aforesaid shall be
         made only against delivery of such Governmental Obligations. For the
         purposes of this Section, "Governmental Obligations" shall mean and
         include only non-callable direct obligations of the Department of the
         Treasury of the United States of America or portions thereof (including
         interest or principal portions thereof), and such Governmental
         Obligations shall be of such amounts, maturities and interest payment
         dates and bear such interest as will, without further investment or
         reinvestment of either the principal amount thereof or the interest
         earnings therefrom, be sufficient to make the payments required herein,
         and which obligations have been deposited in an escrow account which is
         irrevocably pledged as security for the Notes. Such term shall not
         include mutual funds and unit investment trusts.

                  (c)      Any Issuer Derivative Payments are deemed to have
         been paid and the applicable Derivative Product terminated when payment
         of all Issuer Derivative Payments due and payable to each Counterparty
         under its respective Derivative Product have been made or duly provided
         for to the satisfaction of each Counterparty and the respective
         Derivative Product has been terminated.

                  (d)      In no event shall the Trustee deliver over to the
         Issuer any Financed Eligible Loans originated under the Act unless the
         Issuer is an Eligible Lender, if the Act or Regulations then in effect
         require the owner or holder of such Financed Eligible Loans to be an
         Eligible Lender.

                  (e)      The provisions of this Section are applicable to the
         Notes and the Issuer Derivative Payments.

                                       69

<PAGE>

         SECTION 10.03. OPTIONAL PURCHASE OF ALL FINANCED ELIGIBLE LOANS. The
Administrator shall certify to and notify the Sponsor and the Trustee in
writing, within 15 days after the last Business Day of each Collection Period
which the then outstanding Pool Balance is 12% or less of the sum of the Initial
Pool Balance, of the percentage that the then outstanding Pool Balance bears to
such sum. The Sponsor shall have the option to purchase the Financed Eligible
Loans on the date (the "Optional Purchase Date") that is the tenth (10th)
Business Day preceding the earlier of (i) the April _, 2011 Distribution Date or
(ii) the Distribution Date next succeeding the date on which the then
outstanding Pool Balance is 10% or less of the Initial Pool Balance. To exercise
such option, the Sponsor shall deposit in the Collection Fund on the Optional
Purchase Date, an amount equal to the aggregate Purchase Amount for the Financed
Eligible Loans and the related rights with respect thereto, plus the appraised
value of any such other property held by the Trust other than the Funds and
Accounts, such value to be determined by an appraiser mutually agreed upon by
the Sponsor and the Trustee; provided, however, that the Sponsor may not effect
such purchase if such aggregate Purchase Amounts do not equal or exceed the
Minimum Purchase Amount.

         SECTION 10.04. AUCTION OF FINANCED ELIGIBLE LOANS. Any Financed
Eligible Loans remaining in the Trust Estate on the Business Day next succeeding
the Optional Purchase Date shall promptly thereafter be offered for sale by the
Trustee (or its designated agent), and any such sale shall be consummated on or
before the immediately following Distribution Date (the "Trust Auction Date").
The Trustee shall provide written notice to the Sponsor of any such offer for
sale at least three Business Days in advance of the Trust Auction Date. If at
least two bids are received, the Trustee (or its designated agent) shall solicit
and resolicit new bids from all participating bidders until only one bid remains
or the remaining bidders decline to resubmit bids. The Trustee shall accept the
highest of such remaining bids if it is equal to or in excess of both (i) the
Minimum Purchase Amount and (ii) the fair market value of such Financed Eligible
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 (i) the Minimum Purchase Amount and (ii) the fair market value of the
Financed Eligible Loans, the Trustee shall not consummate such sale. The Trustee
may consult, and, at the direction of the Sponsor, shall consult, with a
financial advisor, including an underwriter of the Notes or the Administrator,
to determine if the fair market value of the Financed Eligible Loans has been
offered. The proceeds of any such sale will be applied in the order of priority
set forth in Section 6.02 hereof. Unless requested by the Administrator, if the
sale is not completed, the Trustee may, but will not be obligated to, solicit
bids for sale of the Financed Eligible Loans with respect to future Distribution
Dates upon terms similar to those described above. The Trustee shall be
obligated to make such solicitations, however, if requested to do so by the
Administrator. Notice of the prepayment of any Obligations resulting from a
purchase of the Financed Eligible Loans on the Optional Purchase Date or the
auction of the Financed Eligible Loans on the Trust Auction Date, shall be given
by the Trustee to the Registered Owners by first-class mail within five Business
Days of such Optional Purchase Date or Trust Auction Date.

         SECTION 10.05. CANCELLATION OF PAID NOTES. Any Notes which have been
paid or purchased by the Issuer, mutilated Notes replaced by new Notes, and any
temporary Note for which definitive Notes have been delivered shall (unless
otherwise directed by the Issuer by

                                       70

Issuer Order) forthwith be cancelled by the Trustee and, except for temporary

         This Eligible Loan Acquisition Certificate is submitted pursuant to the

used in this Certificate and not otherwise defined herein shall have the same
meanings given to such terms in the Indenture. In your capacity as Trustee, you
are hereby authorized and requested to disburse to _________________ (the
"Seller") the sum of $__________ (or, in the case of an exchange, the Eligible
Loans listed in Exhibit A hereto) for the acquisition of Eligible Loans. With
respect to the Eligible Loans so to be acquired, the Issuer hereby certifies as
follows:

         1.       The Eligible Loans to be acquired are those specified in
Schedule A attached hereto (the "Acquired Eligible Loans"). The remaining unpaid
principal amount of each Acquired Eligible Loan is as shown on such Schedule A.

         2.       The amount to be disbursed pursuant to this Certificate does
not exceed the amount permitted by Section 5.02 of the Indenture, including a
premium of not to exceed [101.0440%], plus accrued interest.

         3.       Each Acquired Eligible Loan is an Eligible Loan authorized so
to be acquired by the Indenture.

         4.       You have been previously, or are herewith, provided with the
following items (the items listed in (a), (b), (c), (d) and (f) have been
received and are being retained, on your behalf, by the Issuer or the Servicer):

                  (a)      a copy of the Student Loan Purchase Agreement between
         the Issuer and the Eligible Lender with respect to the Acquired
         Eligible Loans (original copy maintained on file with the Issuer on
         behalf of the Trustee);

                  (b)      with respect to each Insured Loan included among the
         Acquired Eligible Loans, the Certificate of Insurance relating thereto;

                  (c)      with respect to each Guaranteed Loan included among
         the Acquired Eligible Loans, a certified copy of the Guarantee
         Agreement relating thereto;

                  (d)      an opinion of counsel to the Issuer specifying each
         action necessary to perfect a security interest in all Eligible Loans
         to be acquired by the Issuer pursuant to the Student Loan Purchase
         Agreements in favor of the Trustee in the manner provided for by the
         provisions of 20 U.S.C. Section 1087-2(d)(3) or 20 U.S.C. Section
         1082(m)(1)(D)(iv), as applicable, (you are authorized to rely on the
         advice of a single blanket opinion of counsel to the Issuer until such
         time as the Issuer shall provide any amended opinion to you);

<PAGE>

                  (e)      a certificate of an Authorized Representative of the
         Issuer to the effect that (i) the Issuer is not in default in the
         performance of any of its covenants and agreements made in the Student
         Loan Purchase Agreement relating to the Acquired Eligible Loans; (ii)
         with respect to all Acquired Eligible Loans which are Insured,
         Insurance is in effect with respect thereto, and with respect to all
         Acquired Eligible Loans which are Guaranteed, the Guarantee Agreement
         is in effect with respect thereto; and (iii) the Issuer is not in
         default in the performance of any of its covenants and agreements made
         in any Contract of Insurance or the Guarantee Agreement applicable to
         the Acquired Eligible Loans; and

Indenture or in the performance of any of its covenants and agreements made in
the Student Loan Purchase Agreement relating to the Acquired Eligible Loans,
and, to the best knowledge of the Issuer, the Eligible Lender is not in default
under the Student Loan Purchase Agreement applicable to the Acquired Eligible
Loans. The Issuer is not aware of any default existing on the date hereof under
any of the other documents referred to in paragraph 4 hereof, nor of any
circumstances which would reasonably prevent reliance upon the opinion of
counsel referred to in paragraph 4(d) hereof.

         6.       All of the conditions specified in the Student Loan Purchase
Agreement applicable to the Acquired Eligible Loans and the Indenture for the
acquisition of the Acquired Eligible Loans and the disbursement hereby
authorized and requested have been satisfied; provided that the Issuer may waive
the requirement of receiving an opinion of counsel from the counsel to the
Lender.

         7.       If a Financed Eligible Loan is being sold in exchange for an
Acquired Eligible Loan, the final expected maturity date of such Acquired
Eligible Loan shall be substantially similar to that of the Financed Eligible
Loan being sold and such sale and exchange shall not adversely affect the
ability of the Trust Estate to make timely principal and interest payments on
its Obligations.

         8.       With respect to all Acquired Eligible Loans which are Insured,
Insurance is in effect with respect thereto, and with respect to all Acquired
Eligible Loans which are Guaranteed, the Guarantee Agreement is in effect with
respect thereto.

         9.       The Issuer is not in default in the performance of any of its
covenants and agreements made in any Contract of Insurance or the Guarantee
Agreement applicable to the Acquired Eligible Loans.

         10.      The proposed use of moneys in the Acquisition Fund is in
compliance with the provisions of the Indenture.

         11.      The undersigned is authorized to sign and submit this
Certificate on behalf of the Issuer.

PRINCIPAL SUM: ONE HUNDRED SEVENTY-THREE MILLION AND 00/00 DOLLARS

         Nelnet Student Loan Trust 2003-1, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, on each Distribution Date the principal sum equal to the
applicable Class A Noteholder's Principal Distribution Amount for such
Distribution Date, as described in the Indenture of Trust dated as of January 1,
2003, between the Issuer (by Wilmington Trust Company, in its capacity as
Delaware Trustee) and Zions First National Bank, a national banking association,
as eligible lender trustee and trustee (the "Trustee") (capitalized terms used
but not defined herein being defined in Article I of the Indenture, which also
contains rules as to usage that shall be applicable herein); provided, however,
that the entire unpaid principal amount of this Note shall be due and payable on
Maturity Date specified above (the "Class A-1 Maturity Date").

         The Issuer shall pay interest on this Note at the rate per annum equal

Interest on this Note shall accrue from and including the preceding Distribution
Date (or, in the case of the first Accrual Period, the Date of Issuance) to but
excluding the following Distribution Date (each an "Accrual Period"). Interest

Accrual Period divided by 360 and rounding the resultant figure to the fifth
decimal point. Such principal of and interest on this Note shall be paid in the
manner specified on the reverse hereof.

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

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

         Unless the certificate of authentication hereon has been executed by

                                     individual capacity but solely as Trustee,

<PAGE>

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

         The Class A-1 Notes are and will be secured by the Trust Estate pledged
as security therefor as provided in the Indenture. The Class A-1 Notes, the
Class A-2 Notes, the Class A-3 Notes and the Class A-4 Notes are 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 equal to the Class A Noteholder's Principal Distribution
Amount for such Distribution Date. "Distribution Date" means the twenty-fifth
(25th) day of each January, April, July, October or, if any such date is not a
Business Day, the immediately succeeding Business Day, commencing July 25, 2003.

         As described on the face hereof, the entire unpaid principal amount of
this Note shall be due and payable on the Class A-1 Maturity Date.
Notwithstanding the foregoing, the entire unpaid principal amount of the Notes
shall be due and payable on the date on which (a) an Event of Default shall have
occurred and be continuing and (b) either the Trustee or the Registered Owners
of Obligations representing not less than a majority of the Outstanding Amount
of the Highest Priority Obligations shall have declared the Notes to be
immediately due and payable in the manner provided in the Indenture.

         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, other than the first
Accrual Period, shall be equal to the applicable Three-Month LIBOR, plus 0.02%.
The "Class A-1 Rate" for the first Accrual Period shall be determined by
reference to the following formula: x + [21/30* (y-x)] (where: x = Five-Month
LIBOR, and y = Six-Month LIBOR), plus 0.02%, as determined by the Administrator.

         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 paid to the Person in whose name such Note is registered on
the Record Date by check mailed first-class, postage prepaid to such Person's
address as it appears on the records of the Trustee on such Record Date, except
that, unless definitive Notes have been issued pursuant to the Indenture, 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. If funds are expected to be available, as provided in the
Indenture, for payment in full of the then remaining unpaid

                                      B-1-4

<PAGE>

principal amount of this Note on a Distribution Date, then the 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.

         As provided in the Indenture and subject to certain limitations set
forth therein, the transfer of this Note may be registered upon the records of
the Trustee upon surrender for transfer of any Note at the Principal Office of
the Trustee, duly endorsed for transfer or accompanied by an assignment duly
executed by the Registered Owner or his attorney duly authorized in writing, and
thereupon the Issuer shall execute and the Trustee shall authenticate and
deliver in the name of the transferee or transferees a new fully registered Note
or Notes of the same interest rate and for a like series, subseries, if any, and
aggregate principal amount of the same maturity.

         As to any Note, the person in whose name the same shall be registered
shall be deemed and regarded as the absolute owner thereof for all purposes, and
payment of either principal or interest on any fully registered Note shall be
made only to or upon the written order of the Registered Owner thereof or his
legal representative but such registration may be changed as provided in the
Indenture. All such payments shall be valid and effectual to satisfy and
discharge the liability upon such Note to the extent of the sum or sums paid.

         Each Registered Owner and each transferee of a Note shall be deemed to
represent and warrant that either (a) it is not acquiring the Note directly or
indirectly for, or on behalf of, an ERISA plan or any entity whose underlying
assets are deemed to be plan assets of such ERISA plan; or (b)(i) the
acquisition and holding of the Notes will not result in a nonexempt prohibited
transaction under Section 406 of ERISA or Section 4975 of the Code or similar
law and (ii) if the Notes are subsequently deemed to be "plan assets" pursuant
to the regulations set forth at 29 C.F.R. Section 2510.3-101, it will promptly
dispose of the Notes.

         The Trustee shall require the payment by any Registered Owner
requesting exchange or transfer of any tax or other governmental charge required
to be paid with respect to such exchange or transfer. The applicant for any such
transfer or exchange may be required to pay all taxes and governmental charges
in connection with such transfer or exchange, other than exchanges pursuant to
the Indenture.

         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 Trustee and the Registered
Owners 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.

         Nelnet Student Loan Trust 2003-1, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, on each Distribution Date the principal sum equal to the
applicable Class A Noteholder's Principal Distribution Amount for such
Distribution Date, as described in the Indenture of Trust dated as of January 1,
2003, between the Issuer (by Wilmington Trust Company, in its capacity as
Delaware Trustee) and Zions First National Bank, a national banking association,
as eligible lender trustee and trustee (the "Trustee") (capitalized terms used
but not defined herein being defined in Article I of the Indenture, which also
contains rules as to usage that shall be applicable herein); provided, however,
that the entire unpaid principal amount of this Note shall be due and payable on
the Maturity Date specified above (the "Class A-2 Maturity Date").

         The Issuer shall pay interest on this Note at the rate per annum equal

Accrual Period divided by 360 and rounding the resultant figure to the fifth
decimal point. Such principal of and interest on this Note shall be paid in the
manner specified on the reverse hereof.

         The principal of and interest on this Note are payable in such coin or

<PAGE>

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

         The Class A-2 Notes are and will be secured by the Trust Estate pledged
as security therefor as provided in the Indenture. The Class A-1 Notes, the
Class A-2 Notes, the Class A-3 Notes and the Class A-4 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 equal to the Class A Noteholder's Principal Distribution
Amount for such Distribution Date. "Distribution Date" means the twenty-fifth
(25th) day of each January, April, July and October or, if any such date is not
a Business Day, the immediately succeeding Business Day, commencing July 25,
2003.

         As described on the face hereof, the entire unpaid principal amount of
this Note shall be due and payable on the Class A-2 Maturity Date.
Notwithstanding the foregoing, the entire unpaid principal amount of the Notes
shall be due and payable on the date on which (a) an Event of Default shall have
occurred and be continuing and (b) either the Trustee or the Registered Owners
of Obligations representing not less than a majority of the Outstanding Amount
of the Highest Priority Obligations shall have declared the Notes to be
immediately due and payable in the manner provided in the Indenture.

         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, other than the first
Accrual Period, shall be equal to the applicable Three-Month LIBOR, plus 0.05%.
The "Class A-2 Rate" for the first Accrual Period shall be determined by
reference to the following formula: x + [21/30* (y-x)] (where: x = Five-Month
LIBOR, and y = Six-Month LIBOR), plus 0.05%, as determined by the Administrator.

         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 paid to the Person in whose name such Note is registered on
the Record Date by check mailed first-class, postage prepaid to such Person's
address as it appears on the records of the Trustee on such Record Date, except
that, unless definitive Notes have been issued pursuant to the Indenture, 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. If funds are expected to be available, as provided in the
Indenture, for payment in full of the then remaining unpaid

                                      B-2-4

<PAGE>

principal amount of this Note on a Distribution Date, then the 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.

         As provided in the Indenture and subject to certain limitations set
forth therein, the transfer of this Note may be registered upon the records of
the Trustee upon surrender for transfer of any Note at the Principal Office of
the Trustee, duly endorsed for transfer or accompanied by an assignment duly
executed by the Registered Owner or his attorney duly authorized in writing, and
thereupon the Issuer shall execute and the Trustee shall authenticate and
deliver in the name of the transferee or transferees a new fully registered Note
or Notes of the same interest rate and for a like series, subseries, if any, and
aggregate principal amount of the same maturity.

         As to any Note, the person in whose name the same shall be registered
shall be deemed and regarded as the absolute owner thereof for all purposes, and
payment of either principal or interest on any fully registered Note shall be
made only to or upon the written order of the Registered Owner thereof or his
legal representative but such registration may be changed as provided in the
Indenture. All such payments shall be valid and effectual to satisfy and
discharge the liability upon such Note to the extent of the sum or sums paid.

         Each Registered Owner and each transferee of a Note shall be deemed to
represent and warrant that either (a) it is not acquiring the Note directly or
indirectly for, or on behalf of, an ERISA plan or any entity whose underlying
assets are deemed to be plan assets of such ERISA plan; or (b)(i) the
acquisition and holding of the Notes will not result in a nonexempt prohibited
transaction under Section 406 of ERISA or Section 4975 of the Code or similar
law and (ii) if the Notes are subsequently deemed to be "plan assets" pursuant
to the regulations set forth at 29 C.F.R. Section 2510.3-101, it will promptly
dispose of the Notes.

         The Trustee shall require the payment by any Registered Owner
requesting exchange or transfer of any tax or other governmental charge required
to be paid with respect to such exchange or transfer. The applicant for any such
transfer or exchange may be required to pay all taxes and governmental charges
in connection with such transfer or exchange, other than exchanges pursuant to
the Indenture.

         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 Trustee and the Registered
Owners under the Indenture.

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

         This Note shall be construed in accordance with the laws of the State

         No reference herein to the Indenture and no provision of this Note or

absolute and unconditional, to pay the principal of and interest on this Note at
the times, place and rate, and in the coin or currency, herein prescribed.

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

         The Class A-3 Notes are and will be secured by the Trust Estate pledged
as security therefor as provided in the Indenture. The Class A-1 Notes, the
Class A-2 Notes, the Class A-3 Notes and the Class A-4 Notes are senior to the
Class B Notes as and to the extent provided in the Indenture.

         Principal of the Class A-3 Notes shall be payable on each Distribution
Date in an amount equal to the Class A Noteholder's Principal Distribution
Amount for such Distribution Date. "Distribution Date" means the twenty-fifth
(25th) day of each January, April, July and October or, if any such date is not
a Business Day, the immediately succeeding Business Day, commencing July 25,
2003.

         As described on the face hereof, the entire unpaid principal amount of
this Note shall be due and payable on the Class A-3 Maturity Date.
Notwithstanding the foregoing, the entire unpaid principal amount of the Notes
shall be due and payable on the date on which (a) an Event of Default shall have
occurred and be continuing and (b) either the Trustee or the Registered Owners
of Obligations representing not less than a majority of the Outstanding Amount
of the Highest Priority Obligations shall have declared the Notes to be
immediately due and payable in the manner provided in the Indenture.

         Interest on the Class A-3 Notes shall be payable on each Distribution
Date on the principal amount outstanding of the Class A-3 Notes until the
principal amount thereof is paid in full, at a rate per annum equal to the Class
A-3 Rate. The "Class A-3 Rate" for each Accrual Period, other than the first
Accrual Period, shall be equal to the applicable Three-Month LIBOR, plus 0.11%.
The "Class A-3 Rate" for the first Accrual Period shall be determined by
reference to the following formula: x + [21/30* (y-x)] (where: x = Five-Month
LIBOR, and y = Six-Month LIBOR), plus 0.11%, as determined by the Administrator.

         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 paid to the Person in whose name such Note is registered on
the Record Date by check mailed first-class, postage prepaid to such Person's
address as it appears on the records of the Trustee on such Record Date, except
that, unless definitive Notes have been issued pursuant to the Indenture, 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. If funds are expected to be available, as provided in the
Indenture, for payment in full of the then remaining unpaid

                                     B-3-4

<PAGE>

principal amount of this Note on a Distribution Date, then the 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.

         As provided in the Indenture and subject to certain limitations set
forth therein, the transfer of this Note may be registered upon the records of
the Trustee upon surrender for transfer of any Note at the Principal Office of
the Trustee, duly endorsed for transfer or accompanied by an assignment duly
executed by the Registered Owner or his attorney duly authorized in writing, and
thereupon the Issuer shall execute and the Trustee shall authenticate and
deliver in the name of the transferee or transferees a new fully registered Note
or Notes of the same interest rate and for a like series, subseries, if any, and
aggregate principal amount of the same maturity.

         As to any Note, the person in whose name the same shall be registered
shall be deemed and regarded as the absolute owner thereof for all purposes, and
payment of either principal or interest on any fully registered Note shall be
made only to or upon the written order of the Registered Owner thereof or his
legal representative but such registration may be changed as provided in the
Indenture. All such payments shall be valid and effectual to satisfy and
discharge the liability upon such Note to the extent of the sum or sums paid.

         Each Registered Owner and each transferee of a Note shall be deemed to
represent and warrant that either (a) it is not acquiring the Note directly or
indirectly for, or on behalf of, an ERISA plan or any entity whose underlying
assets are deemed to be plan assets of such ERISA plan; or (b)(i) the
acquisition and holding of the Notes will not result in a nonexempt prohibited
transaction under Section 406 of ERISA or Section 4975 of the Code or similar
law and (ii) if the Notes are subsequently deemed to be "plan assets" pursuant
to the regulations set forth at 29 C.F.R. Section 2510.3-101, it will promptly
dispose of the Notes.

         The Trustee shall require the payment by any Registered Owner
requesting exchange or transfer of any tax or other governmental charge required
to be paid with respect to such exchange or transfer. The applicant for any such
transfer or exchange may be required to pay all taxes and governmental charges
in connection with such transfer or exchange, other than exchanges pursuant to
the Indenture.

         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 Trustee and the Registered
Owners under the Indenture.

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

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

         The Class A-4 Notes are and will be secured by the Trust Estate pledged
as security therefor as provided in the Indenture. The Class A-1 Notes, the
Class A-2 Notes, the Class A-3 Notes and the Class A-4 Notes are senior to the
Class B Notes as and to the extent provided in the Indenture.

         Principal of the Class A-4 Notes shall be payable on each Distribution

Amount for such Distribution Date. "Distribution Date" means the twenty-fifth

2003.

         As described on the face hereof, the entire unpaid principal amount of

Notwithstanding the foregoing, the entire unpaid principal amount of the Notes

A-4 Rate. The "Class A-4 Rate" for each Accrual Period, other than the first
Accrual Period, shall be equal to the applicable Three-Month LIBOR, plus 0.22%;
provided, however, that if the Sponsor does not exercise its option to purchase
the Financed Eligible Loans as described in the Indenture and the Financed
Eligible Loans are not sold on the Trust Auction Date, the Class A-4 Rate shall
be increased by 0.13% per annum for each Accrual Period beginning on or after
the Optional Purchase Date. The "Class A-4 Rate" for the first Accrual Period
shall be determined by reference to the following formula: x + [21/30* (y-x)]

determined by the Administrator.

on a Distribution Date, then the 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

         Nelnet Student Loan Trust 2003-1, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, on each Distribution Date the principal sum equal to the
applicable Class B Noteholder's Principal Distribution Amount for such
Distribution Date, as described in the Indenture of Trust dated as of January 1,
2003, between the Issuer (by Wilmington Trust Company, in its capacity as
Delaware Trustee) and Zions First National Bank, a national banking association,
as eligible lender trustee and trustee (the "Trustee") (capitalized terms used
but not defined herein being defined in Article I of the Indenture, which also
contains rules as to usage that shall be applicable herein); provided, however,
that the entire unpaid principal amount of this Note shall be due and payable on
the Maturity Date specified above (the "Class B Maturity Date").

         The Issuer shall pay interest on this Note at the rate per annum equal
to the Class B Rate (as defined on the reverse hereof), on each Distribution
Date until the principal of this Note is paid or made available for payment, on
the principal amount of this Note outstanding on the

preceding Distribution Date or the Date of Issuance in the case of the first
Distribution Date (after giving effect to all payments of principal made on the
preceding Distribution Date), subject to certain limitations contained in 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 Date of
Issuance) to but excluding the following Distribution Date (each an "Accrual
Period"). Interest shall be calculated on the basis of the actual number of days
elapsed in each Accrual Period divided by 360 and rounding the resultant figure
to the fifth decimal point. Such principal of and interest on this Note shall be
paid in the manner specified on the reverse hereof.

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

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

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

<PAGE>

         This Note is one of a duly authorized issue of Notes of the Issuer,
designated as its Student Loan-Backed Notes, Class B (the "Class B Notes"),
which, together with the Issuer's Student Loan-Backed Notes, Class A-1, Class
A-2, Class A-3 and Class A-4 (the "Class A-1 Notes," the "Class A-2 Notes, the
"Class A-3 Notes" and the "Class A-4 Notes," respectively) (and, together with
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 Trustee and the Registered Owners. The Notes are subject to all
terms of the Indenture.

         The Class B Notes are and will be secured by the Trust Estate pledged
as security therefor as provided in the Indenture. The Class A-1 Notes, Class
A-2 Notes, Class A-3 Notes and Class A-4 Notes 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 equal to the Class B Noteholder's Principal Distribution
Amount for such Distribution Date. "Distribution Date" means the twenty-fifth
(25th) day of each January, April, July and October or, if any such date is not
a Business Day, the immediately succeeding Business Day, commencing July 25,
2003.

         As described on the face hereof, the entire unpaid principal amount of
this Note shall be due and payable on the Class B Maturity Date. Notwithstanding
the foregoing, the entire unpaid principal amount of the Notes shall be due and
payable on the date on which (a) an Event of Default shall have occurred and be
continuing and (b) either the Trustee or the Registered Owners of Obligations
representing not less than a majority of the Outstanding Amount of the Highest
Priority Obligations shall have declared the Notes to be immediately due and
payable in the manner provided in the Indenture.

         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, other than the first Accrual
Period, shall be equal to the applicable Three-Month LIBOR, plus 0.70%;
provided, however, that if the Sponsor does not exercise its option to purchase
the Financed Eligible Loans as described in the Indenture and the Financed
Eligible Loans are not sold on the Trust Auction Date, the Class B Rate shall be
increased by 0.30% per annum for each Accrual Period beginning on or after the
Optional Purchase Date. The "Class B Rate" for the first Accrual Period shall be
determined by reference to the following formula: x + [21/30* (y-x)] (where: x =
Five-Month LIBOR, and y = Six-Month LIBOR), plus 0.70%, as determined by the
Administrator.

         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 paid to the Person in whose name such Note is registered on
the Record Date by check mailed first-class, postage prepaid to such Person's
address as it appears on the records of the Trustee on such Record Date, except
that, unless definitive Notes have been issued pursuant to the Indenture, 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

                                     B-5-4

<PAGE>

immediately available funds to the account designated by such nominee. 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 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.

         As provided in the Indenture and subject to certain limitations set
forth therein, the transfer of this Note may be registered upon the records of
the Trustee upon surrender for transfer of any Note at the Principal Office of
the Trustee, duly endorsed for transfer or accompanied by an assignment duly
executed by the Registered Owner or his attorney duly authorized in writing, and
thereupon the Issuer shall execute and the Trustee shall authenticate and
deliver in the name of the transferee or transferees a new fully registered Note
or Notes of the same interest rate and for a like series, subseries, if any, and
aggregate principal amount of the same maturity.

         As to any Note, the person in whose name the same shall be registered
shall be deemed and regarded as the absolute owner thereof for all purposes, and
payment of either principal or interest on any fully registered Note shall be
made only to or upon the written order of the Registered Owner thereof or his
legal representative but such registration may be changed as provided in the
Indenture. All such payments shall be valid and effectual to satisfy and
discharge the liability upon such Note to the extent of the sum or sums paid.

         Each Registered Owner and each transferee of a Note shall be deemed to
represent and warrant that either (a) it is not acquiring the Note directly or
indirectly for, or on behalf of, an ERISA plan or any entity whose underlying
assets are deemed to be plan assets of such ERISA plan; or (b)(i) the
acquisition and holding of the Notes will not result in a nonexempt prohibited
transaction under Section 406 of ERISA or Section 4975 of the Code or similar
law and (ii) if the Notes are subsequently deemed to be "plan assets" pursuant
to the regulations set forth at 29 C.F.R. Section 2510.3-101, it will promptly
dispose of the Notes.

         The Trustee shall require the payment by any Registered Owner
requesting exchange or transfer of any tax or other governmental charge required
to be paid with respect to such exchange or transfer. The applicant for any such
transfer or exchange may be required to pay all taxes and governmental charges
in connection with such transfer or exchange, other than exchanges pursuant to
the Indenture.

         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 Trustee and the Registered
Owners under the Indenture.
