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

                                       22
<PAGE>

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

        Each Note shall be dated the Date of Issuance. The terms of the Notes
set forth in Exhibit B hereto are part of the terms of this Indenture.

        SECTION 2.02. EXECUTION, AUTHENTICATION AND DELIVERY OF NOTES. The Notes
shall be executed in the name and on behalf of the Issuer by the manual or
facsimile signature of an Authorized Representative. Any Note may be signed
(manually or by facsimile) or attested on behalf of the Issuer by any person
who, at the date of such act, shall hold the proper office or position,
notwithstanding that at the date of authentication, issuance or delivery, such
person may have ceased to hold such office or position.

        The Trustee shall upon Issuer Order authenticate and deliver Notes for
original issue in an aggregate principal amount of $1,200,435,000. The aggregate
principal amount of Notes Outstanding at any time may not exceed such amount
except as provided in Section 2.04 hereof.

        Each Note shall be dated the date of its authentication. The Notes shall
be issuable as registered Notes, in minimum denominations of $100,000 and in
integral multiples of $1,000 in excess thereof (the "Authorized Denominations").

        No Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears on such Note a
certificate of authentication in accordance with Section 2.05 hereof.

        Each Class of Notes will be initially issued in Book-Entry Form and will
be represented by a book-entry note certificate deposited on the Date of
Issuance with Zions First National Bank, as custodian for the initial Clearing
Agency and registered in the name of "Cede & Co." as initial nominee for the
initial Clearing Agency.

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

                                       23
<PAGE>

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

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

        Each Registered Owner and each transferee of a Note shall be deemed to
represent and warrant that either (a) it is not acquiring the Note directly or
indirectly for, or on behalf of, an ERISA plan or any entity whose underlying
assets are deemed to be plan assets of such ERISA plan; or (b)(i) the
acquisition and holding of the Notes will not result in a nonexempt prohibited
transaction under Section 406 of ERISA or Section 4975 of the Code or similar
law and (ii) if the Notes are subsequently deemed to be "plan assets" pursuant
to the regulations set forth at 29 C.F.R. 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
Section 2.07 hereof.

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

                                       24
<PAGE>

        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.

        SECTION 2.08. ISSUANCE OF NOTES. The Issuer shall have the authority,
upon complying with the provisions of this Article, 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, with the
consent of the applicable Clearing Agency Participants, 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
Master Servicer, a Subservicer or the Administrator under the Master Servicing
Agreement, its related Servicing Agreement or the Administration Agreement,
respectively, Noteholders representing beneficial interests aggregating at least


                                       25
<PAGE>

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 and the applicable Clearing Agency Participants consent to
the termination of the book-entry system through the Clearing Agency, 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. Neither the Issuer nor 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.

        Upon acquisition or transfer of a Definitive Note by, for or with the
assets of, a Benefit Plan, such Noteholder shall be deemed to have represented
that such acquisition or purchase will not constitute or otherwise result in:
(a) in the case of a Benefit Plan subject to Title I of ERISA or Section 4975 of
the Code, a non-exempt prohibited transaction in violation of Section 406 of
ERISA or Section 4975 of the Code which is not covered by a class or other
applicable exemption and (b) in the case of a Benefit Plan subject to a
substantially similar law, a non-exempt violation of such substantially similar
law. Any transfer found to have been made in violation of such deemed
representation shall be null and void and of no effect.

        SECTION 2.10. PAYMENT OF PRINCIPAL AND INTEREST.

                (a) Each Class of Notes shall accrue interest as provided in the
        forms of the Class A-1 Notes, the Class A-2 Notes, the Class A-3 Notes
        and the Class B Notes set forth in Exhibits B-1, B-2, B-3 and B-4
        respectively, hereto. Such interest shall be payable with respect to
        each Class of Notes on each Quarterly Distribution Date as specified in
        Section 5.03(c) hereof, 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
        Quarterly 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 hereof, 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 Quarterly Distribution
        Date or on the Note Final Maturity Date for such Note which shall be
        payable as provided below. The amount of interest distributable to
        Noteholders of the Notes for each $1,000 in principal amount will be
        calculated by applying the applicable interest rate for the Interest
        Accrual Period to the principal amount of $1,000, multiplying that
        product by the actual number of days in the Interest Accrual Period
        divided by 360, and rounding the resulting percentage figure to the
        fifth decimal point.

                                       26
<PAGE>

                (b) The principal of each Note shall be payable in installments
        on each Quarterly Distribution Date as provided in Section 5.03(c)
        hereof. Notwithstanding the foregoing, the entire unpaid principal
        amount of each Class of 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 hereof. The Trustee shall notify the
        Person in whose name a Note is registered on or prior to the close of
        business on the Record Date preceding the applicable Quarterly
        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 or electronic delivery prior
        to such final Quarterly 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.

        SECTION 2.11. NOTICES TO CLEARING AGENCY. Whenever a notice or other
communication is required under this Indenture to be given to Noteholders,
unless and until Definitive Notes shall have been issued to Noteholders pursuant
to Section 2.09 hereof, the Trustee shall give all such notices and
communications specified herein to the applicable Clearing Agency.

                                  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


                                       27
<PAGE>

shall not create or voluntarily permit to be created any debt, lien or charge on
the Financed Eligible Loans which would be on a parity with, subordinate to, or
prior to the lien of this Indenture; shall not do or omit to do or suffer to be
done or omitted to be done any matter or things whatsoever whereby the lien of
this Indenture or the priority of such lien for the Obligations hereby secured
might or could be lost or impaired; and will pay or cause to be paid or will
make adequate provisions for the satisfaction and discharge of all lawful claims
and demands which if unpaid might by law be given precedence to or any equality
with this Indenture as a lien or charge upon the Financed Eligible Loans;
provided, however, that nothing in this Section 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, payments to a Counterparty and (b) the Trustee may receive,
from time to time, Counterparty Payments for the account of the Issuer. No
Derivative Product shall be entered into subsequent to the Date of Issuance
unless the Trustee shall have received a Rating Confirmation from each Rating
Agency that such Derivative Product will not adversely affect the Rating on any
of the Notes.

                                   ARTICLE IV

                       PROVISIONS APPLICABLE TO THE NOTES;
                              DUTIES OF THE ISSUER

        SECTION 4.01. PAYMENT OF PRINCIPAL AND INTEREST. The Issuer covenants
that it will promptly pay, but solely from the Trust Estate, the principal of
and interest, if any, on each and every Obligation issued under the provisions
of this Indenture at the places, on the dates and in the manner specified herein
and in said Obligations according to the true intent and meaning thereof. The
Obligations shall be and are hereby declared to be payable from and equally
secured, except as specifically provided in this Indenture with respect to
certain payment and other priorities, 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.

                                       28
<PAGE>

        SECTION 4.03. FURTHER COVENANTS OF THE ISSUER.

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

                (b) The Issuer will duly and punctually keep, observe and
        perform each and every term, covenant and condition on its part to be
        kept, observed and performed, contained in this Indenture and the other
        agreements to which the Issuer is a party pursuant to the transactions
        contemplated herein, including but not limited to the Basic Documents to
        which it is a party, the Guarantee Agreements and the Certificate of
        Insurance, 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 66-2/3%
        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 Master
        Servicing Agreement, a Subservicing Agreement or a Custodian Agreement.

                                       29
<PAGE>

                (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.

        SECTION 4.04. ENFORCEMENT OF MASTER SERVICING AGREEMENT AND SUBSERVICING
AGREEMENTS. The Issuer shall comply with, shall require the Master Servicer to
comply with and shall cause the Master Servicer to require the Subservicers 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 the Master Servicing Agreement and
        all Subservicing Agreements, including the prompt payment of all amounts

        Subservicer under the Master Servicing Agreement or its related
        Subservicing Agreement in accordance with the terms thereof;

        or a Subservicer of its obligations under the Master Servicing Agreement
        or its related Subservicing Agreement coming to the Issuer's attention;

                (f) the Issuer shall not waive any default by the Master

        Issuer shall send copies of such annual certificate of the Master

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

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

        SECTION 4.06. ADDITIONAL COVENANTS WITH RESPECT TO THE HIGHER EDUCATION
ACT. The Issuer covenants that it will cause the Trustee to be, or replace the
Trustee with, an Eligible Lender under the Higher Education 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 Higher Education 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 Master Servicer, a
Subservicer or a Guaranty 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 Higher
Education Act:

                (a) 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

        shall cause the Financed Eligible Loans to be serviced by entering into
        the Master Servicing Agreement or other agreement with the Master
        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 any regulations or rulings thereunder, with respect to the Financed
        Eligible Loans;

        Agreements, the Interest Benefit Payments and the Special Allowance
        Payments, to flow to the Trustee. The Trustee shall have no liability

        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 Higher Education
        Act to be acquired pursuant to a Student Loan Purchase Agreement with
        the 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."

                                       32

purposes of this Section unless it has agreed in writing to be such agent.

        SECTION 4.07. FINANCED ELIGIBLE LOANS; COLLECTIONS THEREOF; ASSIGNMENT
THEREOF. The Issuer, through the Master Servicer and one or more Subservicers,
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; provided, however, the Issuer may offer interest rate reductions
with respect to the Financed Eligible Loans which result in rates of interest
not less than those shown in the cash flow analyses provided to each Rating
Agency on the Date of Issuance, and provided further that such rates of interest
may be further reduced if a Rating Confirmation is obtained, based on new cash
flow analyses containing such assumptions as the Issuer shall reasonably
determine. 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 Master Servicer or the appropriate Subservicer. The Issuer will comply with
the Higher Education 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, either singly or collectively, shall be personally liable
for any act or omission not willfully fraudulent or mala fide. The Issuer hereby
directs the Trustee to enter into this Indenture, the Administration Agreement,
the Custodian Agreements and the Investment Agreements. The Issuer hereby
directs the Eligible Lender Trustee to enter into this Indenture, the Guarantee
Agreements, the Custodian Agreements and the Eligible Lender Trust Agreement.

        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
statutory trust, except as otherwise permitted by this Section. 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 clauses (a), (b) and (c) above 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.

                                       33
<PAGE>

        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 it that such an amendment is
required by the Higher Education Act and is not materially prejudicial to the
Registered Owners.

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

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

                        (v) NO VIOLATION. The consummation of the transactions
                contemplated by this Indenture and the fulfillment of the terms
                hereof do 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 its affiliates is a party pending,
                or, to the best of its knowledge, threatened, before any court,
                regulatory body, administrative agency or other tribunal or
                governmental instrumentality (A) asserting the invalidity of
                this Indenture, (B) seeking to prevent the issuance of any Notes
                or the consummation of any of the transactions contemplated by
                this Indenture or (C) seeking any determination or ruling that
                might materially and adversely affect the performance by the
                Issuer of its obligations under, or the validity or
                enforceability of this Indenture.

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

                        (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 (through
                the Eligible Lender Trustee) 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.

                                       35
<PAGE>

                        (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 2008-1" and has not changed since its
                inception. The Issuer has no trade names, fictitious names,
                assumed names or "dba's" under which it conducts its business
                and has made no filing in respect of any such name.

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

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

                        (xiv) VALID BUSINESS REASONS; NO FRAUDULENT TRANSFERS.
                The transactions contemplated by this Indenture are in the
                ordinary course of the Issuer's business and the Issuer has
                valid business reasons for granting the Trust Estate pursuant to
                this Indenture. At the time of each such grant: (A) the Issuer
                granted the Trust Estate to the Trustee without 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
                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 Depositor or any affiliate.

                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 and the Master Servicing Agreement or the payment of

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

                Issuer has complied with all applicable federal, state and local

                writing or report delivered to the Trustee, the Master Servicer,
                a Subservicer or any Registered Owner by the Issuer contains any
                untrue statement of a material fact or omits a material fact

        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
                shall satisfy any representations and warranties made with
                respect thereto in an applicable 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
                interest in the Trust Estate, including the Financed Eligible
                Loans, have been made no later than the Date of Issuance and
                copies of the file-stamped financing statements shall be

                (other than the security interest created in favor of the
                Trustee) to be created.

                grant of the Financed Eligible Loans by the Issuer pursuant to
                this Indenture is not subject to the bulk transfer act or any
                similar statutory provisions in effect in any applicable
                jurisdiction.

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

        assets.

                (l) The Issuer will strictly observe legal formalities in its
        dealings with the Seller, the Depositor or any affiliate thereof, and

from an Authorized Representative including (a) a current list of the Authorized

covenants under this Indenture and, in the event of any noncompliance,
specifying such noncompliance and the nature and status thereof. For purposes of
this Section, 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 Colorado, Delaware, Nebraska, and Utah) 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 the Issuer.

                (b) Pursuant to the Higher Education Act, a security interest in
        student loans is perfected in the same manner as "accounts" within the
        meaning of the applicable UCC, which applicable UCCs are the UCC as in
        effect in the States of Delaware and Utah for the purposes of perfecting
        a security interest in the Financed Eligible Loans.

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

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

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

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

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

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

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

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

                (c) The Issuer shall take all steps necessary, and shall cause
        the Master Servicer and each Subservicer, 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.

        SECTION 4.19. BORROWER INCENTIVE PROGRAMS. The Issuer presently offers
borrower incentive programs on the Financed Eligible Loans. If any such
incentive programs, or any other borrower incentive programs offered by the
Issuer in the future which are not required by the Higher Education Act, are in
effect for any Financed Eligible Loans on any Quarterly Distribution Date on
which the Parity Ratio is less than 100%, the Issuer shall either (i) contribute
funds to the Collection Fund in an amount equal to the principal or interest
that otherwise would have been paid on such Financed Eligible Loans in the
absence of the borrower incentive programs since the preceding Quarterly
Distribution Date or (ii) notify the Master Servicer to instruct the
Subservicers to notify the borrowers that the borrower incentive programs for
those Financed Eligible Loans have been terminated. If the Master Servicer or a
Subservicer is notified to provide notice of the termination of the borrower
incentive programs for the Financed Eligible Loans being serviced by such Master
Servicer or the Subservicer, such Master Servicer or Subservicer may choose to
contribute funds to the Collection Fund in an amount equal to the principal or
interest that otherwise would have been paid on such Financed Eligible Loans in
the absence of the borrower incentive programs on the Financed Eligible Loans
being serviced by such Master Servicer or Subservicer in lieu of providing
notice of the termination of the borrower incentive programs for those Financed
Eligible Loans. The Issuer shall notify the Rating Agencies if the Issuer, the
Master Servicer or a Subservicer contributes any additional amounts pursuant to
this Section or if any of the borrower incentive programs are terminated.

        SECTION 4.20. STATEMENTS TO NOTEHOLDERS. Two days preceding a Quarterly
Distribution Date, the Issuer shall cause the Administrator to provide to the
Trustee (with a copy to the Rating Agencies) a report setting forth the
information described in Item 1122 of Regulation AB promulgated by the
Securities and Exchange Commission substantially in the form of Exhibit E
hereto, with such additional information as the Administrator shall determine;
the Trustee shall forward such report on or before the Quarterly Distribution
Date to the Registered Owners.

                                      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 Prefunding Account therein;

                (b) Collection Fund;

                (c) Department Rebate Fund; and

                (d) 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
$1,197,457,905. In addition, the Issuer shall deposit $1,786,736 of its own
funds to the Acquisition Fund. There shall be deposited into the Prefunding
Account of the Acquisition Fund from the proceeds of the Notes deposited to the
Acquisition Fund an amount equal to $178,000,000. Financed Eligible Loans shall
be held by the Trustee or its agent or bailee (including the Master Servicer or
a Subservicer) and shall be pledged to the Trust Estate and held as a part of
the Acquisition Fund.

        Moneys on deposit in the Acquisition Fund, including the Prefunding
Account of the Acquisition Fund, shall be used upon receipt by the Trustee of an
Eligible Loan Acquisition Certificate, to acquire Eligible Loans at a price not
in excess of 100% of the outstanding principal balance of such Eligible Loans,
plus accrued interest. Any such Eligible Loan Acquisition Certificate shall
state that such proposed use of moneys in the Prefunding Account is in
compliance with the provisions of this Indenture.

        In addition, on each Monthly Servicing Payment Date or Quarterly
Distribution Date, to the extent there are insufficient Available Funds in the
Collection Fund to make one or more of the transfers required by Section 5.03(b)
(other than transfers to repurchase student loans from the Master Servicer, and
Subservicer or any Guaranty Agency as described in clause (a)(i) of the
definition of Available Funds) and 5.03(c)(i) through (iv) and (vii) hereof, the
Administrator shall instruct the Trustee in writing to withdraw from the


                                       44
<PAGE>

Acquisition Fund (first from the Prefunding Account therein) on such Monthly
Servicing Payment Date or Quarterly Distribution Date, as the case may be, an
amount of money (but not Eligible Loans) equal to such deficiency and to deposit
such amount in the Collection Fund. Notwithstanding the foregoing, if any funds
or moneys remain in the Acquisition Fund (including the Prefunding Account) on
May 1, 2008, then the Trustee shall, without direction from or notice to the
Issuer, transfer all such remaining moneys or funds to the Collection Fund.

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

        Except (i) as provided in Sections 5.07, 10.03 and 10.04 hereof, (ii)
for consolidation or serialization purposes, (iii) for transfers to a Guaranty
Agency, (iv) for transfers to the Master Servicer or a Subservicer pursuant to
its repurchase obligation under the applicable Master Servicing Agreement or
Subservicing Agreement, (v) for transfers to a Seller pursuant to its repurchase
obligation under its Student Loan Purchase Agreement, or (vi) as set forth in
the following sentence, Financed Eligible Loans shall not be sold, transferred
or otherwise disposed of by the Issuer while any of the Notes are Outstanding.
If necessary for administrative purposes, the Issuer may sell Financed Eligible
Loans through the Eligible Lender Trustee free from the lien of this Indenture,
so long as the sale price for any Financed Eligible Loan is not less than the
Purchase Amount of such Financed Eligible Loan and the collective aggregate
principal balance of all such sales does not exceed $10,000,000, and the Issuer
hereby certifies the same to the Trustee, upon which the Trustee may
conclusively rely. The Issuer hereby certifies, upon which the Trustee may
conclusively rely, that any Financed Eligible Loan sold pursuant to this
Indenture shall not be sold for a price less than the Purchase Amount of such
Financed Eligible Loan. The Issuer shall provide notice to Moody's if the
principal amount of Financed Eligible Loans sold pursuant to this Indenture
exceeds 10% of the Initial Pool Balance.

        SECTION 5.03. COLLECTION FUND.

                (a) DEPOSITS TO COLLECTION FUND. There shall be deposited to the
        Collection Fund (i) moneys from proceeds of the Notes in an amount equal
        to $0, (ii) all Available Funds, and all other moneys and investments
        derived from assets on deposit in and transfers from the Acquisition
        Fund (as described in Section 5.02 hereof), the Reserve Fund (as
        described in Section 5.04 hereof) and the Department Rebate Fund (as
        described in Section 5.05 hereof), (iii) all Counterparty Payments, (iv)
        amounts deposited pursuant to Sections 10.03 and 10.04 hereof and (v)
        any other amounts deposited thereto upon receipt of deposit instructions
        from the Issuer or the Administrator as applicable. Moneys on deposit in
        the Collection Fund shall be used to make the payments described in this
        Section. The Trustee may conclusively rely on all written instructions
        of the Issuer or Administrator described in this Indenture with no
        further duty to examine or determine the information contained in any
        Administrator's Quarterly Distribution Date Certificate, Monthly
        Servicing Payment Date Certificate, or Issuer Order.

                                       45
<PAGE>

                (b) PAYMENTS ON DATES OTHER THAN QUARTERLY DISTRIBUTION DATES.
        The Administrator shall instruct the Trustee in writing no later than
        the Determination Date for the Monthly Servicing Payment Date (based on
        the information contained in a certificate of the Administrator (in the
        form set forth as Exhibit C hereto) and the related Servicer's Report,
        if applicable) to distribute to the Master Servicer, on such Monthly
        Servicing Payment Date, from and to the extent of the Available Funds on
        deposit in the Collection Fund (including any amounts transferred from
        the Acquisition Fund pursuant to Section 5.02 hereof and the Reserve
        Fund pursuant to Section 5.04(b) and (c) hereof), the Servicing Fees due
        with respect to the preceding calendar month, and the Trustee shall
        comply with such instructions. In accordance with Section 5.05 hereof,
        the Administrator shall instruct the Trustee in writing on a monthly
        basis not later than the 10th calendar day of each month to withdraw
        from the Collection Fund and deposit to the Department Rebate Fund the
        amount necessary to bring the balance of the Department Rebate Fund to
        the expected Department Rebate Interest Amount for such date, and the
        Trustee shall comply with such instructions. Upon written direction from
        the Administrator to the Trustee, moneys in the Collection Fund shall be
        used on any date to pay, when due, fees and expenses insofar as the same
        relate to Financed Eligible Loans and other fees and expenses with
        respect to the Trust Estate the payment of which is not otherwise
        provided for in subsection (c) of this Section, but including, without
        limitation, amounts described in clause (a)(i) and (ii) of the
        definition of Available Funds.

                (c) PAYMENTS ON QUARTERLY DISTRIBUTION DATES. The Administrator
        shall instruct the Trustee in writing no later than the Determination
        Date preceding each Quarterly Distribution Date (based on the
        information contained in a certificate of the Administrator (in the form
        set forth as Exhibit D hereto) and the related Servicer's Report, if
        applicable) to make the following deposits and distributions from the
        Available Funds in the Collection Fund received during the immediately
        preceding Collection Period (including any amounts transferred from the
        Acquisition Fund pursuant to Section 5.02 hereof and the Reserve Fund
        pursuant to Section 5.04(b) and (c) hereof) to the Persons or to the
        account specified below on such Quarterly Distribution Date, in the
        following order of priority, and the Trustee shall comply with such
        instructions, provided, however, that if the Available Funds received
        during the immediately preceding Collection Period are not sufficient to
        make the payments or deposits required pursuant to clauses (i) through
        (v) of this subsection (c), then, after any required transfers from the
        Acquisition Fund and the Reserve Fund, any other Available Funds on
        deposit in the Collection Fund, which the Administrator would have
        deemed Available Funds for the current Collection Period, may be used to
        make the payments or deposits required pursuant to clauses (i) through
        (v) of this subsection (c):

                the Cutoff Date but prior to the Date of Issuance, until such
                amount has been paid in full;

                        (x) in the event the Financed Eligible Loans are not
                sold pursuant to Sections 10.03 or 10.04 hereof, to pay as an
                accelerated payment of principal balance of the Notes then
                Outstanding, to the Noteholders in the same order and priority

               The Administrator shall, or shall direct the Trustee to, notify
        the Rating Agencies, by forwarding a copy of Exhibit D hereto, if the
        Available Funds received during the immediately preceding Collection
        Period are not sufficient to make the payments or deposits required
        pursuant to clauses (i) through (v) of this subsection (c), after any
        required transfers from the Acquisition Fund and the Reserve Fund, and
        such payments or deposits were made with other Available Funds on
        deposit in the Collection Fund from the current Collection Period.

               Subject to the provisions of Sections 7.05 and 7.07 hereof, the
        Issuer hereby certifies that the amounts paid to the Trustee and the
        Delaware Trustee (but not the Master Servicer) pursuant to clause (i)
        above and the Administration Fee pursuant to clause (ii) above, shall
        not in any one Fiscal Year exceed the amount or percentage designated
        therefor in the cash flows provided to each Rating Agency on the Date of
        Issuance, unless the Issuer, after furnishing each Rating Agency with
        revised cash flows, shall have received a Rating Confirmation.

                (d) OPTIONAL REDEMPTION FROM SALE OF FINANCED ELIGIBLE LOANS.

        $2,977,095 into the Reserve Fund. Thereafter, the Trustee shall transfer

        transfer thereto pursuant to Section 5.03(c)(vii) hereof.

                                       48
<PAGE>

                (b) On each Monthly Servicing Payment Date or Quarterly
        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) (other than transfers to repurchase student loans from
        the Master Servicer, any Subservicer or any Guaranty Agency as described
        in clause (a)(i) of the definition of Available Funds) and 5.03(c)(i)
        through (c)(iv) hereof, then the Administrator shall instruct the
        Trustee in writing to withdraw from the Reserve Fund on such Monthly
        Servicing Payment Date or Quarterly Distribution Date, as the case may
        be, an amount equal to such deficiency and to deposit such amount in the
        Collection Fund to the extent moneys are not available to make such
        transfers from the Acquisition Fund pursuant to Section 5.02 hereof.
        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 for application to payment of the
        Outstanding Amount of such Class of Notes.

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

                (d) On the final Quarterly Distribution Date upon termination of
        the trust and following the payment in full of the Outstanding Amount of
        the Notes and of all other amounts (other than unpaid Issuer Derivative
        Payments and Carryover Servicing Fees) owing or to be distributed
        hereunder to Noteholders, the Trustee, the Master Servicer, the
        Administrator, the Delaware Trustee or the Counterparties (excluding
        Termination Payments other than Priority Termination Payments), 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 Issuer Derivative 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
        Depositor. The Depositor shall in no event be required to refund any
        amounts properly distributed pursuant to this subsection (d).

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

        SECTION 5.05. DEPARTMENT REBATE FUND. On or before the 10th calendar day
of each month (or, if such date is not a Business Day, the next Business Day),
the Administrator shall instruct the Trustee to deposit into the Department
Rebate Fund from the Collection Fund pursuant to Section 5.03(b) hereof the
amount necessary to bring the balance of the Department Rebate Fund to the
expected Department Rebate Interest Amount for such date. Upon written
instructions from the Administrator to the Trustee, the Trustee shall (i) pay to
the Department an amount equal to the Department Rebate Interest Amount due on
each Department Rebate Payment Date, FIRST, from amounts on deposit in the
Department Rebate Fund and, second, from the Collection Fund pursuant to Section
5.03(b) hereof or (ii) if the Department has deducted the Department Rebate
Interest Amount from Interest Subsidy Payments or Special Allowance Payments due
to the Issuer, transfer the amounts on deposit in the Department Rebate Fund to
the Collection Fund.

        SECTION 5.06. 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, to the fullest extent practicable and
reasonable, in Investment Securities which shall mature or be redeemed at the
option of the holder prior to the respective dates when the money held for the
credit of such Fund or Account will be required for the purposes intended. In
the absence of any such direction and to the extent practicable, the Trustee
shall invest amounts held hereunder in those Investment Securities described in
clause (k) of the definition of the Investment Securities. All such investments
shall be held by (or by any custodian on behalf of) the Trustee for the benefit
of the Issuer; provided that on the Business Day preceding each Quarterly
Distribution Date and Monthly Servicing Payment 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 Quarterly 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, the Trustee shall use its best
efforts to sell at the best price obtainable, or present for redemption, any
Investment Securities purchased by it as an investment whenever it shall be
necessary to provide money to meet any payment from the applicable Fund. The
Trustee shall advise the Issuer in writing, on or before the fifteenth day of
each calendar month (or such later date as reasonably consented to by the
Issuer), of all investments held for the credit of each Fund in its custody
under the provisions of this Indenture as of the end of the preceding month and
the value thereof, and shall list any investments which were sold or liquidated
for less than the par value thereof, plus accrued but unpaid interest at the
time thereof.

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

                                       50
<PAGE>

        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 5.07. 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 hereof, 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
        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 hereof and all amounts payable to the Master Servicer, each
        Subservicer, the Administrator, the Delaware Trustee and the
        Counterparties 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 subsection (c)
        only upon receipt of an Issuer Order, an Opinion of Counsel and (if
        required by the Trust Indenture Act) Independent Certificates in
        accordance with Sections 314(c) and 314(d)(1) of the Trust Indenture
        Act.

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

                (e) Each Registered Owner, by the acceptance of a Note,
        acknowledges that from time to time the Trustee shall release the lien
        of this Indenture on any Financed Eligible Loan to be sold or
        transferred pursuant to Section 5.02 hereof, 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; provided, however, that a
        default in the due and punctual payment of any interest on any Class B
        Note shall not be an Event of Default if any Class A Notes are
        Outstanding;

                (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; provided, however, that a default in the due and punctual
        payment of principal on any Class B Note shall not be an Event of
        Default if any Class A Notes are Outstanding;

                (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 hereof 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. The Trustee may give any such notice in
its discretion and shall give such notice if requested to do so in writing by
the Registered Owners of at least 51% of the collective aggregate principal
amount of the Highest Priority Obligations at the time Outstanding.

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

                                       52
<PAGE>

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

                SECOND, to the Master Servicer, any Servicing Fees due and
        remaining unpaid;

               THIRD, pro rata, based on amounts due and owing, to (i) the
        Counterparties, pro rata, without preference or priority of any kind, in
        proportion to their respective entitlements under the applicable
        Derivative Products (excluding all Termination Payments other than
        Priority Termination Payments) and (ii) to the Class A Noteholders of
        each Class for amounts due and unpaid on each such Class of Class A
        Notes for interest, ratably, without preference or priority of any kind,
        according to the amounts due and payable on each such Class of Class A
        Notes for such interest;

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

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

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

               SEVENTH, to the Counterparties, in proportion to the respective
        entitlements under the applicable Derivative Product Agreement, ratably,
        without preference or priority of any kind, for any Termination Payments
        due and any other unpaid Issuer Derivative Payments;

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

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

        The Trustee may fix a record date and payment date for any payment to
Registered Owners pursuant to this Section. 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.

                                       53
<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 a majority of the principal amount of the Highest
Priority Obligations at the time Outstanding.

        Notwithstanding the foregoing, the Trustee is prohibited from selling
the Financed Eligible Loans following an Event of Default, other than a default
in the payment of any principal or interest on any Note, unless:

                (a) The Registered Owners of all of the Highest Priority
        Obligations at the time Outstanding consent to such a sale;

                (b) The proceeds of such a sale will be sufficient to discharge
        all the Outstanding Obligations pursuant to Article X hereof at the date
        of such a sale; or

                (c) The Issuer, or the Administrator on behalf of the Issuer,
        determines that the collections on the Financed Eligible Loans would not
        be sufficient on an ongoing basis to make all payments on such
        Obligations as such payments would have become due if such Obligations
        had not been declared due and payable, and the Trustee obtains the
        consent of the Registered Owners of at least 66-2/3% of the aggregate
        principal amount of the Highest Priority Obligations at the time
        Outstanding.

                                       54
<PAGE>

Such a sale shall also require the consent of all the Registered Owners of the
Class B Notes unless the proceeds of such a sale would be sufficient to
discharge the Class B Notes pursuant to Article X hereof at the date of such a
sale.

        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.

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

        SECTION 6.08. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT. If an
Event of Default should occur and be continuing, then and in every such case the
Trustee or the Registered Owners of Obligations representing not less than a
majority of the Outstanding Amount of the Highest Priority Obligations may
declare all the Outstanding Obligations to be immediately due and payable, by a
notice in writing to the Issuer (and to the Trustee if given by the Registered
Owners), and upon any such declaration the unpaid principal amount of such
Outstanding 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 hereof.

        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 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

                                       55
<PAGE>

                        (ii) all sums paid or advanced by the Trustee hereunder
                and the reasonable compensation, expenses, disbursements and
                advances of the Trustee, the Master Servicer, any Subservicer
                and the Delaware Trustee and their agents and counsel; and

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

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

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

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

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

                (b) default is made in the payment of the principal of (or
        premium, if any, on) any Notes at their 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 Class 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.

                                       56
<PAGE>

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

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

                                       57
<PAGE>

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

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

        SECTION 6.15. 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 Section 313(c) of the Trust Indenture
Act, 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 determines
that the withholding of such notice is in the interest of the Registered Owners
of the Notes. For the purpose of this Section, 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.

                                  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.

                (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) 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) 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) to give 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


                                       59
<PAGE>

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. All reasonable costs incurred by the Trustee and all reasonable
compensation to all such persons as may reasonably be employed in connection
with the trusts hereof shall be paid by the Issuer.

        SECTION 7.05. INDEMNIFICATION OF TRUSTEE. Other than with respect to its
duties to make payment on the Obligations when due and its duty to pursue the
remedy of acceleration as provided respectively in Sections 6.02 and 6.08
hereof, for each of which no additional security or indemnity may be required,
the Trustee shall be under no obligation or duty to perform any act at the
request of Registered Owners or to institute or defend any suit in respect
thereof unless properly indemnified and provided with security to its
satisfaction as provided in Section 7.01(c) hereof. The Trustee shall not be
required to take notice, or be deemed to have knowledge, of any default or Event
of Default of the Issuer hereunder and may conclusively assume that there has
been no such default or Event of Default (other than an Event of Default
described in Section 6.01(a) or (b) hereof) unless and until it shall have been
specifically notified in writing at the address in Section 9.01 hereof of such
default or Event of Default by (a) the Registered Owners of the required
percentages in principal amount of the Obligations then Outstanding hereinabove
specified or (b) an Authorized Representative. 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, 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


                                       60
<PAGE>

only to the prior lien of the Notes for the payment of the principal thereof,
premium, if any, and interest thereon from the Collection Fund. None of the
provisions contained in this Indenture or any other agreement to which it is a
party shall require the Trustee to act or to expend or risk its own funds or
otherwise incur individual financial liability in the performance of any of its
duties or in the exercise of any of its rights or powers if the Registered
Owners shall not have offered security and indemnity acceptable to it or if it
shall have reasonable grounds for believing that prompt repayment of such funds
or adequate indemnity against such risk or liability is not reasonably assured
to it.

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

        SECTION 7.06. TRUSTEE'S RIGHT TO RELIANCE. The Trustee shall be
protected in acting upon any notice, resolution, request, consent, order,
certificate, report, appraisal, opinion, report or document of the Issuer, the
Administrator, the Master Servicer or a Subservicer 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 or an authorized officer of
the Administrator, the Master Servicer or a Subservicer.

        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.

                                       61
<PAGE>

        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 materially increase the
Trustee Fee without giving the Issuer and each Rating Agency at least 90 days'
written notice prior to the beginning of a Fiscal Year. If not paid by the
Issuer, the Trustee shall have a lien against all money held pursuant to this
Indenture, subject only to the prior lien of the Obligations against the money
and investments in the Collection Fund for the payment of the principal thereof,
premium, if any, and interest thereon, for such reasonable compensation,
expenses, advances and counsel fees incurred in and about the execution of the
trusts hereby created and the exercise and performance of the powers and duties
of the Trustee hereunder and the cost and expense incurred in defending against
any liability in the premises of any character whatsoever (unless such liability
is adjudicated to have resulted from the negligence or willful misconduct of the
Trustee).

        SECTION 7.08. CREDITOR RELATIONSHIPS. The Trustee shall comply with
Section 311(a) of the Trust Indenture Act, excluding any creditor relationship
listed in Section 311(b) of the Trust Indenture Act. A Trustee who has resigned
or been removed shall be subject to Section 311(a) of the Trust Indenture Act to
the extent indicated therein. 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
clause (a) above, the Issuer may remove such temporary successor Trustee and
appoint a successor thereto pursuant to Section 7.11 hereof.

                                       62
<PAGE>

        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.

        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 Trustee, as 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 Higher Education Act with respect to the Financed
Eligible Loans originated under the Higher Education 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, 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, shall
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.

                                       63
<PAGE>

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

        SECTION 7.13. ADDITIONAL COVENANTS BY THE TRUSTEE TO CONFORM TO THE
HIGHER EDUCATION ACT. The Trustee covenants that it will at all times (a) be an
Eligible Lender under the Higher Education Act so long as such designation is
necessary, as determined by the Issuer, (b) maintain the guarantees and federal
benefits under the Higher Education Act with respect to the Financed Eligible
Loans, (c) acquire Eligible Loans originated under the Higher Education Act in
its capacity as an Eligible Lender and (d) not knowingly dispose of or deliver
any Financed Eligible Loans originated under the Higher Education Act or any
security interest in any such Financed Eligible Loans to any party who is not an
Eligible Lender so long as the Higher Education 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 Master Servicer, a Subservicer or a
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 AGREEMENTS. The Trustee acknowledges the receipt
of copies of the Master Servicing Agreement and Subservicing Agreements
described in Section 4.04 hereof.

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

                                       64
<PAGE>

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

        SECTION 7.18. NOTICES TO RATING AGENCIES. It shall be the duty of the
Issuer to notify each Rating Agency then rating any of the Notes of (a) any
amendment, change, expiration, extension or renewal of this Indenture, (b)
prepayment or defeasance of all the Notes, (c) any change in the Trustee, (d)
any other information reasonably required to be reported to each Rating Agency
under any Supplemental Indenture or (e) any amendment to or transfer of an
Investment Agreement; 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:

        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 MASTER SERVICER OR A SUBSERVICER.
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 Master Servicer or a Subservicer while such Master Servicer
or Subservicer is acting as bailee or agent of the Trustee with respect to the
Eligible Loans for actions taken in compliance with any instruction or direction
given to the Trustee, or for the application of funds or moneys by the Master
Servicer or a Subservicer 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.

        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 Section 310(a)(1) of the Trust Indenture Act
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, 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, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article. Neither
the Issuer nor any Person directly or indirectly controlling or controlled by,
or under common control with, the Issuer shall serve as Trustee.

                                       66
<PAGE>

        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 Class shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Issuer for the payment of overdue principal,
premium, if any, or interest) shall be entitled and empowered, by intervention
in such proceeding or otherwise:

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

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

        Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Registered Owner of
a Note any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Registered Owner thereof, or to
authorize the Trustee to vote in respect of the claim of any Registered Owner of
a Note in any such proceeding.

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

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

                             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, Master
        Servicer or Subservicer;

                (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 Higher Education 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;

                (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 or obtain more
        favorable treatment under any current or future law, rule or regulation,
        including but not limited to the Higher Education Act, the Regulations
        or the Code and the regulations promulgated thereunder;

                                       68
<PAGE>

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

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

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

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

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

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

        If at any time the Issuer shall request the Trustee to enter into any
such Supplemental Indenture for any of the purposes of this Section, the Trustee
shall, upon being satisfactorily indemnified with respect to expenses, cause
notice of the proposed execution of such 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
permitted and provided, this Indenture shall be and be deemed to be modified and
amended in accordance therewith.

<PAGE>

        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
Higher Education Act or granting of a security interest therein to any Person
other than an Eligible Lender, the Master Servicer or a Subservicer, unless the
Higher Education Act or Regulations are hereafter modified so as to permit the
same. The Trustee may request an opinion of counsel to the effect that an
amendment or supplement to this Indenture was adopted in conformance with this
Indenture.

        SECTION 8.04. CONFORMITY WITH THE TRUST INDENTURE ACT. Every
supplemental indenture executed pursuant to this Article shall conform to the
requirements of the Trust Indenture Act as then in effect.

                                   ARTICLE IX

                               GENERAL PROVISIONS

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

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.

                                       71
<PAGE>

        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 a 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 a 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
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
and the Utah 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 Trust Indenture
Act that are required to be part of this Indenture and shall, to the extent
applicable, be governed by such provisions.

        SECTION 9.10. SEVERABILITY. If any covenant, agreement, waiver, or part
thereof contained in this Indenture shall 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,
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. LIMITATIONS ON COUNTERPARTY RIGHTS. No Counterparty which
shall be in default under any Derivative Product with the Issuer shall have any
of the rights granted to a Counterparty or as the Registered Owner of an
Obligation hereunder. A Counterparty which is in default under any Derivative
Product shall, however, continue to maintain all obligations undertaken by it
under the terms of its Derivative Product. No Counterparty shall have any
consent or voting rights under this Indenture or any rights to instruct the
Trustee to take, or refrain from taking, any action hereunder except upon
satisfaction of a Rating Confirmation.

        SECTION 9.16. DISCLOSURE OF NAMES AND ADDRESSES OF REGISTERED OWNERS.

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

                (b) 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 Clearing Agency 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 Section 312 of the
        Trust Indenture Act, 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 Section 312(b) of the Trust Indenture Act.

        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 M&T Trust
Company of Delaware, but are made and intended for the purpose of only binding
the Trust Estate, as defined in the Trust Agreement, and the Issuer; (c) nothing
contained herein shall be construed as creating any liability on M&T Trust
Company of Delaware, 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 M&T Trust Company of Delaware, 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 is 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; (ii) to each Counterparty, all Issuer
        Derivative Payments then due, then the pledge of the Trust Estate, and
        all covenants, agreements and other obligations of the Issuer to the
        Registered Owners of Notes and (iii) all other obligations due and
        outstanding 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 respective 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
        Corporation or fully collateralized by Governmental Obligations) in an
        amount 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


                                       75
<PAGE>

        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, and all other obligations due and
        outstanding, as the case may be. If moneys and/or Governmental
        Obligations are deposited with and held by the Trustee as provided in
        this subsection (b), such moneys and/or Governmental Obligations shall
        be accompanied by a report of a nationally recognized independent
        certified public accountant firm or other financial services firm
        verifying that the amount of such moneys and/or Governmental Obligations
        deposited will be sufficient, together with interest to accrue thereon,
        to pay all the Notes at or before their Maturity. 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 and all other
        obligations due and outstanding 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 Higher Education Act unless
        the Issuer is an Eligible Lender, if the Higher Education 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 Depositor, or any assignee of its
rights hereunder, and the Trustee in writing, within 15 days after the last
Business Day of each Collection Period in which the then outstanding Pool
Balance is 12% or less of the Initial Pool Balance, of the percentage that the
then outstanding Pool Balance bears to the Initial Pool Balance. The Depositor
or its assignee shall have the option to purchase all of the Financed Eligible
Loans on the earlier of (a) the November 2015 Quarterly Distribution Date and
(b) the date that is the tenth (10th) Business Day preceding the Quarterly
Distribution Date next succeeding the last day of the Collection Period on which
the then outstanding Pool Balance is 10% or less of the Initial Pool Balance
(each, an "Optional Purchase Date"). To exercise the option described in this
Section, the Depositor or its assignee shall deposit in the Collection Fund on
the Optional Purchase Date, an amount equal to the aggregate Purchase Amount for
the Financed Eligible Loans as of the last Business Day of the preceding
Collection Period and the related rights with respect thereto, plus the
appraised value of any such other property held in the Trust Estate other than
the Funds and Accounts, such value to be determined by an appraiser mutually
agreed upon by the Depositor or its assignee and the Trustee; provided, however,
that the Depositor or its assignee may not effect such purchase if such
aggregate Purchase Amount and the appraised value of such other property do not
equal or exceed the Minimum Purchase Amount, less any amounts on deposit in the
Funds and Accounts.

        SECTION 10.04. AUCTION OF FINANCED ELIGIBLE LOANS. If the Depositor, or
any assignee of its rights under Section 10.03 hereof, does not exercise its
option to purchase Financed Eligible Loans pursuant to Section 10.03 hereof, the
Trustee (or its designated agent) shall, promptly after the Business Day next
succeeding the Optional Purchase Date, offer for sale Financed Eligible Loans in
an amount sufficient to redeem all Notes Outstanding on such Quarterly
Distribution Date, and any such sale shall be consummated on or before such
Quarterly Distribution Date (the "Trust Auction Date"). Nelnet, Inc. or its
Affiliates and unrelated third parties may bid to purchase the Financed Eligible
Loans. The Trustee shall provide written notice to the Depositor of any such
offer for sale at least three Business Days in advance of the Trust Auction
Date. If at least two independent 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 the remaining bids if it is equal
to or in excess of both (i) the Minimum Purchase Amount, less any amounts on
deposit in the Funds and Accounts 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 the amounts described in the preceding sentences, the
Trustee shall not consummate such sale. The Trustee may consult, and, at the
direction of the Depositor, shall consult, with a financial advisor, including
an underwriter of the Notes or the Administrator, to determine if the fair
market value of the Financed Eligible Loans has been offered. The proceeds of
any such sale shall be deposited to the Collection Fund and applied to the
redemption of all Notes Outstanding in accordance with Section 5.03(d) hereof.
Unless requested by the Administrator, if the sale is not completed, the Trustee
may, but will not be obligated to, solicit bids for sale of the Financed


                                       77
<PAGE>

Eligible Loans with respect to future Quarterly Distribution Dates upon terms
similar to those described above. The Trustee shall be obligated to make such
solicitations, however, if requested to do so by the Administrator. Notice of
the prepayment of any Obligations resulting from a purchase of the Financed
Eligible Loans on the Optional Purchase Date or the auction of the Financed
Eligible Loans on the Trust Auction Date, shall be given by the Trustee to the
Registered Owners by first-class mail within five Business Days of such Optional
Purchase Date or Trust Auction Date.

        SECTION 10.05. CANCELLATION OF PAID NOTES. Any Notes which have been
paid or purchased by the Issuer, mutilated Notes replaced by new Notes, and any
temporary Note for which definitive Notes have been delivered shall (unless
otherwise directed by the Issuer by Issuer Order) forthwith be cancelled by the
Trustee and, except for temporary Notes, returned to the Issuer.

                      ELIGIBLE LOAN ACQUISITION CERTIFICATE


        This Eligible Loan Acquisition Certificate is submitted pursuant to the
provisions of Section 5.02 of the Indenture of Trust, dated as of March 1, 2008,
as amended (the "Indenture"), between Nelnet Student Loan Trust 2008-1 (the

in this Certificate and not otherwise defined herein shall have the same
meanings given to such terms in the Indenture. In your capacity as Trustee, you
are hereby authorized and requested to disburse to _________________ (the
"Seller") the sum of $__________ 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, plus accrued
interest.

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

        4. The following items have been received and are being retained, on
your behalf, by the Issuer, the Master Servicer or a Subservicer:

               (a) a copy of the Student Loan Purchase Agreement(s) 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)(E), 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); and

               (e) instruments duly assigning the Acquired Eligible Loans to the

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


<PAGE>

        6. All of the conditions specified in the Student Loan Purchase
Agreement(s) 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. 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.

        8. 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.

        9. The proposed use of moneys in the Acquisition Fund (including the
Prefunding Account) is in compliance with the provisions of the Indenture.

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

        Nelnet Student Loan Trust 2008-1, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, on each Quarterly Distribution Date the principal sum equal
to the portion of the Principal Distribution Amount allocable to this Note for
such Quarterly Distribution Date, as described in the Indenture of Trust, dated
as of March 1, 2008, between the Issuer (by M&T Trust Company of Delaware, in
its capacity as Delaware Trustee) and Zions First National Bank, a national
banking association, as eligible lender trustee and indenture trustee (the
"Trustee") (capitalized terms used but not defined herein being defined in
Article I of the Indenture, which also contains rules as to usage that shall be
applicable herein); provided, however, that the entire unpaid principal amount
of this Note shall be due and payable on the Maturity Date specified above (the
"Class A-1 Maturity Date").

<PAGE>

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

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

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

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

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

        This Note is one of a duly authorized issue of Notes of the Issuer,
designated as its Student Loan Asset-Backed Notes, Senior Class A-1 (the "Class
A-1 Notes"), which, together with the Issuer's Student Loan Asset-Backed Notes,
Senior Class A-2 and Class A-3 (together with the Class A-1 Notes, the "Class A
Notes") and the Issuer's Student Loan Asset-Backed Notes, Subordinate Class B
(the "Class B Notes" and, together with the Class A 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 Indenture provides that the Issuer may enter into a derivative
product (a "Derivative Product") between the Issuer and a derivative provider (a
"Counterparty"), as originally executed and as amended or supplemented, or other
interest rate hedge agreement between the Issuer and a Counterparty, as
originally executed and as amended or supplemented. Payments due to a
Counterparty from the Issuer pursuant to the applicable Derivative Product are
referred to herein as "Issuer Derivative Payments," and may be paid on a parity
with interest on any class of the Notes.

        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 Notes are senior
to the Class B Notes as and to the extent provided in the Indenture. The Class A
Notes are, except for certain Termination Payments that are not Priority
Termination Payments, issued on a parity with any Derivative Products entered
into by the Issuer with a Counterparty, pursuant to which the Issuer will, from
time to time, owe Issuer Derivative Payments, and will, from time to time, be
owed Counterparty Payments.

        Principal of the Class A-1 Notes shall be payable on each Quarterly
Distribution Date in an amount equal to the portion of the Principal
Distribution Amount allocable to this Note for such Quarterly Distribution Date.
"Quarterly Distribution Date" means the twenty-fifth (25th) day of each
February, May, August or November, if any such date is not a Business Day, the
immediately succeeding Business Day, commencing May 27, 2008.

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

        The Notes are subject to redemption from the proceeds of a sale of
Financed Eligible Loans in accordance with Section 10.03 or 10.04 of the
Indenture on any Quarterly Distribution Date on or after (a) the November 2015
Quarterly Distribution Date and (b) the Quarterly Distribution Date next
succeeding the date on which the then outstanding Pool Balance is 10% or less of
the Initial Pool Balance (all as defined in the Indenture), in whole only, at a
redemption price equal to the principal amount thereof being redeemed, plus
accrued interest, if any, due and payable on the Notes to such Quarterly
Distribution Date.

        Interest on the Class A-1 Notes shall be payable on each Quarterly
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 Interest Accrual Period, other
than the first Interest Accrual Period, shall be equal to the applicable
Three-Month LIBOR, plus 0.55%. The "Class A-1 Rate" for the first Interest
Accrual Period shall be determined by reference to the following formula:

        x + [15/29* (y-x)] plus 0.55%, as determined by the Administrator.

        where:

        x = Two-Month LIBOR, and

        y = Three-Month LIBOR.

        Payments of interest on this Note on each Quarterly 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 this Note on a Quarterly 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 Quarterly 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 Quarterly 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 Class 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.

preceding Quarterly Distribution Date (or, in the case of the first Interest
Accrual Period, the Date of Issuance) to but excluding the following Quarterly
Distribution Date (each an "Interest Accrual Period"). Interest shall be

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

the reverse hereof, which shall have the same effect as though fully set forth
on the face of this Note.

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

<PAGE>


        This Note is one of a duly authorized issue of Notes of the Issuer,
designated as its Student Loan Asset-Backed Notes, Senior Class A-3 (the "Class
A-3 Notes"), which, together with the Issuer's Student Loan Asset-Backed Notes,
Senior Class A-1 and Class A-2 (together with the Class A-3 Notes, the "Class A
Notes") and the Issuer's Student Loan Asset-Backed Notes, Subordinate Class B
(the "Class B Notes" and, together with the Class A 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 Indenture provides that the Issuer may enter into a derivative
product (a "Derivative Product") between the Issuer and a derivative provider (a
"Counterparty"), as originally executed and as amended or supplemented, or other
interest rate hedge agreement between the Issuer and a Counterparty, as
originally executed and as amended or supplemented. Payments due to a
Counterparty from the Issuer pursuant to the applicable Derivative Product are
referred to herein as "Issuer Derivative Payments," and may be paid on a parity
with interest on any class of the Notes.

        The Class A-3 Notes are and will be secured by the Trust Estate pledged
as security therefor as provided in the Indenture. The Class A Notes are senior
to the Class B Notes as and to the extent provided in the Indenture. The Class A
Notes are, except for certain Termination Payments that are not Priority
Termination Payments, issued on a parity with any Derivative Products entered
into by the Issuer with a Counterparty, pursuant to which the Issuer will, from
time to time, owe Issuer Derivative Payments, and will, from time to time, be
owed Counterparty Payments.

        Principal of the Class A-3 Notes shall be payable on each Quarterly
Distribution Date in an amount equal to the portion of the Principal
Distribution Amount allocable to this Note for such Quarterly Distribution Date.
"Quarterly Distribution Date" means the twenty-fifth (25th) day of each
February, May, August or November, if any such date is not a Business Day, the
immediately succeeding Business Day, commencing May 27, 2008.

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

        The Notes are subject to redemption from the proceeds of a sale of
Financed Eligible Loans in accordance with Section 10.03 or 10.04 of the
Indenture on any Quarterly Distribution Date on or after (a) the November 2015
Quarterly Distribution Date and (b) the Quarterly Distribution Date next
succeeding the date on which the then outstanding Pool Balance is 10% or less of
the Initial Pool Balance (all as defined in the Indenture), in whole only, at a
redemption price equal to the principal amount thereof being redeemed, plus
accrued interest, if any, due and payable on the Notes to such Quarterly
Distribution Date.

                                     B-3-4

<PAGE>

        Interest on the Class A-3 Notes shall be payable on each Quarterly
Distribution Date on the principal amount outstanding of the Class A-3 Notes
until the principal amount thereof is paid in full, at a rate per annum equal to
the Class A-3 Rate. The "Class A-3 Rate" for each Interest Accrual Period, other
than the first Interest Accrual Period, shall be equal to the applicable
Three-Month LIBOR, plus 1.15%. The "Class A-3 Rate" for the first Interest
Accrual Period shall be determined by reference to the following formula:

        x + [15/29* (y-x)] plus 1.15%, as determined by the Administrator.

        where:

        x = Two-Month LIBOR, and

        y = Three-Month LIBOR.

        Payments of interest on this Note on each Quarterly 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 this Note on a Quarterly 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 Quarterly 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 Quarterly 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 Class 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.

represent and warrant that either (a) it is not acquiring the Note directly or

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

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.

provided in the Indenture, subject to certain limitations therein set forth.

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

        Nelnet Student Loan Trust 2008-1, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, on each Quarterly Distribution Date the principal sum equal
to the portion of the Principal Distribution Amount allocable to this Note for
such Quarterly Distribution Date, as described in the Indenture of Trust, dated
as of March 1, 2008, between the Issuer (by M&T Trust Company of Delaware, in
its capacity as Delaware Trustee) and Zions First National Bank, a national
banking association, as eligible lender trustee and indenture trustee (the
"Trustee") (capitalized terms used but not defined herein being defined in
Article I of the Indenture, which also contains rules as to usage that shall be
applicable herein); provided, however, that the entire unpaid principal amount
of this Note shall be due and payable on the Maturity Date specified above (the
"Class B Maturity Date").



<PAGE>

        The Issuer shall pay interest on this Note at the rate per annum equal
to the Class B Rate (as defined on the reverse hereof), on each Quarterly
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
Quarterly Distribution Date or the Date of Issuance in the case of the first
Quarterly Distribution Date (after giving effect to all payments of principal
made on the preceding Quarterly Distribution Date), subject to certain
limitations contained in the Indenture. Interest on this Note shall accrue from
and including the preceding Quarterly Distribution Date (or, in the case of the
first Interest Accrual Period, the Date of Issuance) to but excluding the
following Quarterly Distribution Date (each an "Interest Accrual Period").
Interest shall be calculated on the basis of the actual number of days elapsed
in each Interest Accrual Period divided by 360 and rounding the resultant figure
to the fifth decimal point. Such principal of and interest on this Note shall be
paid in the manner specified on the reverse hereof.

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

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

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

<PAGE>


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

        The Indenture provides that the Issuer may enter into a derivative
product (a "Derivative Product") between the Issuer and a derivative provider (a
"Counterparty"), as originally executed and as amended or supplemented, or other
interest rate hedge agreement between the Issuer and a Counterparty, as
originally executed and as amended or supplemented. Payments due to a
Counterparty from the Issuer pursuant to the applicable Derivative Product are
referred to herein as "Issuer Derivative Payments," and may be paid on a parity
with interest on any class of the Notes.

        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 Notes are senior to
the Class B Notes as and to the extent provided in the Indenture. The Class A
Notes are, except for certain Termination Payments that are not Priority
Termination Payments, issued on a parity with any Derivative Products entered
into by the Issuer with a Counterparty, pursuant to which the Issuer will, from
time to time, owe Issuer Derivative Payments, and will, from time to time, be
owed Counterparty Payments.

        Principal of the Class B Notes shall be payable on each Quarterly
Distribution Date in an amount equal to the portion of the Principal
Distribution Amount allocable to this Note for such Quarterly Distribution Date.
"Quarterly 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 May 27, 2008.

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

        The Notes are subject to redemption from the proceeds of a sale of
Financed Eligible Loans in accordance with Section 10.03 or 10.04 of the
Indenture on any Quarterly Distribution Date on or after (a) the November 2015
Quarterly Distribution Date and (b) the Quarterly Distribution Date next
succeeding the date on which the then outstanding Pool Balance is 10% or less of
the Initial Pool Balance (all as defined in the Indenture), in whole only, at a
redemption price equal to the principal amount thereof being redeemed, plus
accrued interest, if any, due and payable on the Notes to such Quarterly
Distribution Date.

                                      B-4-4

<PAGE>

        Interest on the Class B Notes shall be payable on each Quarterly
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 Interest Accrual Period, other than
the first Interest Accrual Period, shall be equal to the applicable Three-Month
LIBOR, plus 1.25%. The "Class B Rate" for the first Interest Accrual Period
shall be determined by reference to the following formula:

        x + [15/29* (y-x)] plus 1.25%, as determined by the Administrator.

        where:

        x = Two-Month LIBOR, and

        y = Three-Month LIBOR.

        Payments of interest on this Note on each Quarterly 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 this Note on a Quarterly 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 Quarterly 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 Quarterly 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 Class 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
New York, without reference to its conflict of law provisions, and the
obligations, rights and remedies of the parties hereunder and thereunder shall
be determined in accordance with such laws.

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