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.

                                       22

        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.

                                       23
<PAGE>

                (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 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. All principal payments on the Notes
        shall be made pro rata to the Registered Owners entitled thereto,
        subject, however, to the last paragraph of Section 5.03 hereof. 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


                                       24
<PAGE>

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 subsection (c) 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 (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, Issuer Derivative Payments 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 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.

                                       25
<PAGE>

                (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 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:

                (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 and of 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 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;

                (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, 2003, 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 statue 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 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;

                                       28
<PAGE>

                (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 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

the Custodian Agreements, the Guarantee Agreements 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.

        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
business 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,

                of the Trust Estate to the Trustee have been duly authorized by
                the Issuer by all necessary business 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.

                or official, required on the part of the Issuer in connection

                        (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 2002-1" 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 business 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 any intent to
                hinder, delay or 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
                was reasonably equivalent to the value of the related grant.

                        (xv) NO MANAGEMENT OF AFFAIRS OF SELLER. The Issuer is
                not and will not be involved in the day-to-day management of the
                Seller, the Administrator, the Sponsor or any affiliate.

                        (xvi) NO TRANSFERS WITH SELLER OR AFFILIATES. Other than
                the acquisition of assets and the transfer of any Notes pursuant
                to this Indenture, the Issuer does not engage in and will not
                engage in any transactions with the Seller and affiliates,
                except as provided herein with respect to the 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 its
                obligations under this Indenture.

                        (xviii) FINANCIAL CONDITION. No material adverse change
                has occurred in the Issuer's financial status since the date of
                its formation.

                        (xix) EVENT OF DEFAULT. No Event of Default has 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 LEGAL. The
                Issuer has complied with all applicable federal, state and local
                laws and regulations in connection with its 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.

                (b) The Issuer will not:

                        (i) sell, transfer, exchange or otherwise dispose of any
                portion of the Trust Estate except as expressly permitted by
                this Indenture;

                        (ii) claim any credit on, or make any deduction from,
                the principal amount of any of the Notes by reason of the
                payment of any taxes levied or assessed upon any portion of the
                Trust Estate;

                        (iii) except as otherwise provided herein, dissolve or
                liquidate in whole or in part, except with the prior written
                consent of the Trustee, and to the extent Notes remain
                Outstanding, approval of the Registered Owners and a Rating
                Confirmation;

                        (iv) permit the validity or effectiveness of this
                Indenture, any Supplement or any grant hereunder to be impaired,
                or permit the lien of this Indenture to be amended,
                hypothecated, subordinated, terminated or discharged, or permit
                any Person to be released from any covenants or obligations
                under this Indenture, except as may be expressly permitted
                hereby;

                        (v) except as otherwise provided herein, permit any
                lien, charge, security interest, mortgage or other encumbrance
                (other than the lien of this Indenture) to be created on or
                extend to or otherwise arise upon or burden the Trust Estate or
                any part thereof or any interest therein or the proceeds
                thereof;

                        (vi) permit the lien of this Indenture not to constitute
                a valid first priority, perfected security interest in the Trust
                Estate;

                        (vii) incur or assume any indebtedness or guarantee any

                        (xi) consent to the appointment of a conservator or
                receiver or liquidator in any insolvency, readjustment of debt,

                or relating to the Issuer or of or relating to all or
                substantially all of its property, or a decree or order of a
                court or agency or supervisory authority having jurisdiction in
                the premises for the appointment of a conservator or receiver or
                liquidator in any insolvency, readjustment of debt, marshalling
                of assets and liabilities or similar proceedings, or for the
                winding-up or liquidation of its affairs, shall have been
                entered against the Issuer; or the Issuer shall not consent to
                the appointment of a receiver, conservator or liquidator in any
                insolvency, readjustment of debt, marshalling of assets and
                liabilities, voluntary liquidation or similar proceedings of or

                (c) The Issuer makes the following representations and
        warranties as to the Trust Estate which is granted to the Trustee
        hereunder on such date, on which the Trustee relies in accepting the
        Trust Estate. Such representations and warranties shall survive 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 the Financed
                Eligible Loans to the Trustee.

                        (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

specifying such noncompliance and the nature and status thereof. For purposes of
this Section 4.16, such compliance shall be determined without regard to any
period of grace or requirement of notice under this Indenture.

        SECTION 4.17. REPRESENTATIONS OF THE ISSUER REGARDING THE TRUSTEE'S
SECURITY INTEREST. The Issuer hereby represents and warrants for the benefit of
the Trustee and the Registered Owners as follows:

                (a) This Indenture creates a valid and continuing 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

                (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.

                                       38
<PAGE>

                (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.

                (f) All executed copies of each promissory note and master
        promissory note that constitute or evidence the Financed Eligible Loans
        have been delivered to either the Trustee or the Servicer (as custodian
        for the Trustee).

                (g) The Issuer has received a written acknowledgment from the
        Servicer (as custodian for the Trustee) that the Servicer is holding the
        promissory notes that constitute or evidence the Financed Eligible Loans

                (h) 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

        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 (including a Pre-Funding Account therein);

                (b) Collection Fund; and

                                       39
<PAGE>

                (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.

        SECTION 5.02. ACQUISITION FUND. There shall be deposited into the
Acquisition Fund moneys from proceeds of the Notes in an amount equal to
$1,027,470,340. The Initial Pre-Funded Amount shall be deposited in a
Pre-Funding Account to be created within the Acquisition Fund. The Trustee shall
transfer any moneys which remain in the Pre-Funding Account at the end of the
Pre-Funding Period to the Collection Fund. 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 and (b) upon receipt by
the Trustee of an Eligible Loan Acquisition Certificate, to acquire Eligible
Loans at a price not in excess of 100.935%. 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 Pre-Funding
Account upon the expiration of the Pre-Funding Period, 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 immediately succeeding the expiration of the
Pre-Funding Period.

        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 owner of the Loan and that
the Trustee 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.

        investments derived from assets on deposit in and transfers from the

        contained in a certificate of the Administrator's (in the form set forth

        the Servicer, by 1:00 p.m. (New York time) on such Monthly Servicing

                Class B Noteholders until the principal balance of the Class B
                Notes is reduced to zero, provided that the amount of such
                distribution shall not exceed the outstanding principal balance
                of the Class A Notes or the Class B Notes, as applicable, after
                giving effect to all other payments in respect of principal of
                Class A Notes and Class B Notes to be made on such date; and

                        (xiii) to the Sponsor, any remaining portion thereof.
                Amounts properly distributed to the Sponsor pursuant to this
                paragraph (xiii) 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
        $3,045,404 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)(ix) hereof.


                                       42
<PAGE>

                (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)(v), then the 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) In the event of a termination of a Derivative Product that
        requires the Issuer to make a termination payment to the applicable
        Counterparty, such termination payment shall be paid in the same order
        of priority as the Derivative Product Fee in Section 5.03(c)(iii) and
        the Derivative Product Payment in Section 5.03(c)(x), as the case may
        be; provided, however, that in the event that the Issuer is required to
        make a termination payment to a Counterparty as a result of (i) an Event
        of Default (as such term is defined in the Derivative Product) where the
        Counterparty is the Defaulting Party (as such term is defined in the
        Derivative Product); or (ii) a Termination Event (as such term is
        defined in the Derivative Product), such termination payment will be
        subordinate in priority to the right of the Class A Noteholders to
        receive the Class A Noteholders' Distribution Amount and to the Class B
        Noteholders to receive the Class B Noteholders' Distribution Amount and,
        if necessary, to the reinstatement of the balance of the Reserve Fund up
        to the Specified Reserve Fund Balance. In the event of a termination of
        a Derivative Product that requires the Issuer to make a termination
        payment to the applicable Counterparty except as described in the
        proviso above, the Administrator promptly shall notify the Rating
        Agencies of such requirement and, within thirty (30) days of such
        termination payment, shall provide to the Rating Agencies cash flows and
        such other financial information with respect to the Issuer as the
        Rating Agencies may reasonably request.

                (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).

                                       43
<PAGE>

                (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
may 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 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.

                                       44
<PAGE>

        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 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 accompanied by an Officers' Certificate
        of the Issuer, an Opinion of Counsel and (if required by the TIA)
        Independent Certificates in accordance with TIA Sections 314(c) and
        314(d)(1).

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

                                       45
<PAGE>

                (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,
"Events of Default":

                (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 related Note Final
        Maturity Date;

                (c) default in the performance or observance of any other of the
        covenants, agreements or conditions on the part of the Issuer to be
        kept, observed and performed contained in this Indenture or in the
        Notes, and continuation of such default for a period of 90 days after
        written notice thereof by the Trustee to the Issuer; and

                (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
Section 6.09 hereof, upon the happening and continuance of any Event of Default,
the Trustee personally 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:

                                       46
<PAGE>

               FIRST,  to the  Trustee  and the  Delaware  Trustee,  any Trustee

               SECOND, to the Servicer for due and unpaid Servicing Fees;

               THIRD, to the Counterparties, in proportion to their respective

        or priority, for any due and unpaid Derivative Product Fees;

               FOURTH, to the Class A Noteholders for amounts due and unpaid on
        the Class A Notes for interest, ratably, without preference or priority

        Notes for such interest;

               FIFTH, 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;

               SIXTH, 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;

               SEVENTH, 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;

               EIGHTH, to the Counterparties, in proportion to the respective

        and

               TENTH, 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.

                                       47
<PAGE>

        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 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.

                                       48
<PAGE>

        SECTION 6.07. PURCHASE OF PROPERTIES BY TRUSTEE OR REGISTERED OWNERS. In
case of any such sale of the Trust Estate, any Registered Owner or Registered
Owners or committee of Registered Owners or the Trustee, may bid for and
purchase such property and upon compliance with the terms of sale may hold,
retain possession and dispose of such property as the absolute right of the
purchaser or purchasers without further accountability and shall be entitled,
for the purpose of making any settlement or payment for the property purchased,
to use and apply any Obligations hereby secured and any interest thereon due and
unpaid, by presenting such Obligations in order that there may be credited
thereon the sum apportionable and applicable thereto out of the net proceeds of
such sale, and thereupon such purchaser or purchasers shall be credited on
account of such purchase price payable to him or them with the sum apportionable
and applicable out of such net proceeds to the payment of or as a credit on the
Obligations so presented.

        SECTION 6.08. 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 6.09. 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 6.15
        hereof.

                                       49
<PAGE>

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

SECTION 6.10. 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 6.11. 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.

        SECTION 6.12. 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 6.12 shall be expressly subject to the provisions of Sections
7.01(c) and 7.05 hereof.

        SECTION 6.13. 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.

<PAGE>

        SECTION 6.14. 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 6.15. 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 Section 7.05 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.

                                  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.

                                       53
<PAGE>

        SECTION 7.05. INDEMNIFICATION OF TRUSTEE. Other than with respect to its
duties to make payment on the Obligations when due, and its duty to pursue the
remedy of acceleration as provided in Section 6.02 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.

<PAGE>

        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 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).

                                       55
<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.

                                       56
<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.

                                       57
<PAGE>

        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 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 Trustee 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 except, to the extent provided in any Servicing
Agreement or custodian agreement, 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.

                                       60
<PAGE>

        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 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.

                                  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 Section 3.03 hereof 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.

                                       62
<PAGE>

        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 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 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


                                       63
<PAGE>

Obligations may be executed by 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.

        All notices, requests and other communications to any party hereunder
shall be in writing (including bank wire, telex, telecopy or facsimile or
similar writing) at the following addresses, and each address shall constitute

effective when delivered by hand or received by facsimile or registered
first-class mail, postage prepaid.

        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 charge payable directly or indirectly from


                                       65
<PAGE>

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 the Obligations, any right,


                                       66
<PAGE>

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. Other than rights to the payment of
Derivative Product Fees and Derivative Product Payments as described in Section
5.04(d) hereof, 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 and the Derivative Value of any Derivative Product.

        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

<PAGE>

Trust Estate, as defined in the Trust Agreement, and the Issuer; (c) nothing
contained herein shall be construed as 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.

                        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


                                       68
<PAGE>

        which shall be sufficient, or 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.

        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 and the Initial Pre-Funded Amount, 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 May, 2012
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. If the sale is not consummated in accordance
with the foregoing, the Trustee may, but shall not be under any obligation to,
solicit bids for sale of the Financed Eligible Loans with respect to future
Distribution Dates upon terms similar to those described above. 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 Issuer Order) forthwith be cancelled by the
Trustee and, except for temporary Notes, returned to the Issuer.

        This Eligible Loan Acquisition Certificate is submitted pursuant to the
provisions of Section 5.02 of the Indenture of Trust, dated as of May 1, 2002,
as amended (the "Indenture"), between Nelnet Student Loan Trust 2002-1 (the

are hereby authorized and requested to disburse to _________________ (the
"Lender") 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 ___%.

        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. ss. 1087-2(d)(3) or 20 U.S.C. ss. 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

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 paragraphs 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: FOUR HUNDRED FIFTEEN MILLION AND 00/100 DOLLARS
REGISTERED OWNER:     CEDE & CO.

        Nelnet Student Loan Trust 2002-1, a business trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the principal sum of [Note Face Amount] DOLLARS payable on
each Distribution Date in an amount equal to the result obtained by multiplying
(a) a fraction the numerator of which is [Note Face Amount] and the denominator
of which is [Total Class A-1 Note Amount] by (b) the aggregate amount, if any,
payable to Class A-1 Noteholders on such Distribution Date in respect of
principal of the Notes pursuant to the Indenture of Trust dated as of May 1,
2002, 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").
<PAGE>

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

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

                                [REVERSE OF NOTE]


        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 (the
"Class A-2 Notes") and the Issuer's Student Loan-Backed Notes, Class B (the
"Class B Notes" and, together with the Class A-1 Notes and the Class A-2 Notes
the "Notes"), are issued under and secured by the Indenture, to which Indenture
and all indentures supplemental thereto reference is hereby made for a statement
of the respective rights and obligations thereunder of the Issuer, the 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 and the
Class A-2 Notes are senior to the Class B Notes as and to the extent provided in
the Indenture.

        Principal of the Class A-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 February, May, August and November or, if any such date is
not a Business Day, the immediately succeeding Business Day, commencing August
26, 2002.

        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) the Trustee or the Registered Owners of
Obligations representing not less than a majority of the Outstanding Amount of
the Obligations shall have declared the Notes to be immediately due and payable
in the manner provided in the Indenture. All principal payments on the Class A-1
Notes shall be made pro rata to the Registered Owners entitled thereto.

        Interest on the Class A-1 Notes shall be payable on each Distribution
Date on the principal amount outstanding of the Class A-1 Notes until the
principal amount thereof is paid in full, at a rate per annum equal to the Class
A-1 Rate. The "Class A-1 Rate" for each Accrual Period, other than the first
Accrual Period, shall be equal to the applicable Three-Month LIBOR, plus 0.04%.
The "Class A-1 Rate" for the first Accrual Period shall be determined by
reference to the following formula: x + [6/30 * (y-x)] (where: x = Three-Month
LIBOR, and y = Four-Month LIBOR), plus 0.04%, 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

                                      B-1-4
<PAGE>
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. ss. 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 of

        No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of and interest on this Note at

registered assigns, the principal sum of [Note Face Amount] DOLLARS payable on
each Distribution Date in an amount equal to the result obtained by multiplying
(a) a fraction the numerator of which is [Note Face Amount] and the denominator

payable to Class B Noteholders on such Distribution Date in respect of principal

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

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

360. Such principal of and interest on this Note shall be paid in the manner
specified on the reverse hereof.

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

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

entitled to any benefit under the Indenture referred to on the reverse hereof,

                                [REVERSE OF NOTE]


        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 (the
"Class A-1 Notes") and the Issuer's Student Loan-Backed Notes, Class A-2 (the
"Class A-2 Notes" and, together with the Class B Notes and the Class A-1 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 and Class
A-2 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 A Noteholder's Principal Distribution
Amount for such Distribution Date. "Distribution Date" means the twenty-fifth
(25th) day of each February, May, August and November or, if any such date is
not a Business Day, the immediately succeeding Business Day, commencing August
26, 2002.

        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) the Trustee or the Registered Owners of Obligations
representing not less than a majority of the Outstanding Amount of the
Obligations shall have declared the Notes to be immediately due and payable in
the manner provided in the Indenture. All principal payments on the Class B
Notes shall be made pro rata to the Registered Owners entitled thereto.

        Interest on the Class B Notes shall be payable on each Distribution Date
on the principal amount outstanding of the Class B Notes until the principal
amount thereof is paid in full, at a rate per annum equal to the Class B Rate.
The "Class B Rate" for each Accrual Period, other than the first Accrual Period,
shall be equal to the applicable Three-Month LIBOR, plus 0.55%. The "Class B
Rate" for the first Accrual Period shall be determined by reference to the
following formula: x + [6/30 * (y-x)] (where: x = Three-Month LIBOR, and y =
Four-Month LIBOR), plus 0.55% , 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 principal amount of

                                      B-3-4
<PAGE>

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. ss. 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.
