 BB&T CORPORATION NON-EMPLOYEE DIRECTORS’

DEFERRED COMPENSATION AND STOCK OPTION PLAN

          THIS
DECLARATION OF AMENDMENT NO. 2 is made effective as of the 1st day of
January, 2005, by BB&T CORPORATION (“BB&T”), to the BB&T
Corporation Non-Employee Directors’ Deferred Compensation and Stock Option
Plan (the “Plan”). 

R E C I T A L S:

          WHEREAS,
Section 3.1.3 of the Plan provides that an election by a Participant to defer
his Retainer Fee or Meeting Fees pursuant to Section 3.1.1 of the Plan must be
made at a time determined by the Committee; and 

          WHEREAS,
new Section 409A of the Internal Revenue Code of 1986, as amended
(“Code”), which was enacted as part of the American Jobs Creation Act
of 2004, imposes new requirements on nonqualified deferred compensation plans
and will affect certain deferral elections made by Participants in 2005 under
the Plan; and 

          WHEREAS,
Question and Answer 21 of Notice 2005-1, the initial guidance on Code Section
409A published by the United States Department of the Treasury, provides that a
corporation may allow certain deferral elections for 2005 to be made on or
before March 15, 2005, if pursuant to a plan amendment adopted on or before
December 31, 2005; and 

          WHEREAS,
pursuant to Section 10 of the Plan, the Board of Directors of BB&T may amend
the Plan at any time, subject to the terms of the Plan; and 

          WHEREAS,
it is deemed advisable to amend the Plan to permit deferral elections for 2005
to be made on or before March 15, 2005 and to otherwise provide that the Plan is
intended to comply with Code Section 409A, where applicable; and 

          WHEREAS,
pursuant to previously adopted resolutions of the Board of Directors of
BB&T, Robert E. Greene was granted the authority to amend the non-qualified
deferred compensation arrangements maintained by BB&T (including but not
limited to the Plan) in order to comply with Code Section 409A and to make such
other changes as are deemed necessary or advisable under Code Section 409A; 

          NOW,
THEREFORE, IT IS DECLARED that, effective as of January 1, 2005, the Plan shall
be amended by adding a new Section 15 (“Timing of 2005 Deferrals and
Compliance with Internal Revenue Code Section 409A”) to read as follows: 

	 	“15.1  
Timing of 2005 Deferrals — The requirements of Section 3.1.3
relating to the timing of deferral elections shall not apply to any deferral
elections for 2005 made on or before March 15, 2005, provided that (a) the
amounts to which the deferral election relates have not been paid or become
payable at the time of the election, (b) the Plan was in existence on or before
December 31, 2004, (c) the elections to defer compensation are made in
accordance with the terms of the Plan as in effect on December 31, 2005 (other
than a requirement to make a deferral election after March 15, 2005), (d) the
Plan is otherwise operated in accordance with the requirements of Section 409A
of the Code with respect to deferrals subject to Section 409A, and (e) the Plan
is amended to comply with Section 409A in accordance with the statute and
related regulations and other guidance. 

	 	15.2  
Compliance with Code Section 409A — Notwithstanding any other
provision in the Plan or any agreement to the contrary, if and to the extent
that Section 409A of the Code is deemed to apply to the Plan, it is the general
intention of BB&T that the Plan shall comply with Code Section 409A, related
regulations or other guidance, and the Plan shall, to the extent practicable, be
construed in accordance therewith. Without in any way limiting the effect of the
foregoing, in the event that Code Section 409A, related regulations or other
guidance require that any special terms, provisions, or conditions be included
in the Plan, then such terms, provisions and conditions shall, to the extent
practicable, be deemed to be made a part of the Plan. Further, in the event that
the Plan shall be deemed not to comply with Code Section 409A or any other
related regulations or other guidance, then neither BB&T, the Board of
Directors of BB&T, the Compensation Committee of the Board, nor their
designees or agents shall be liable to any person for actions, decisions or
determinations made in good faith.” 

          IN
WITNESS WHEREOF, this Declaration of Amendment No. 2 is executed on behalf of BB&T
Corporation effective as of the day and year first above written.

                               INDENTURE OF TRUST

        THIS INDENTURE OF TRUST, dated as of February 1, 2006 (this
"Indenture"), is by and between NELNET STUDENT LOAN TRUST 2006-1 (the "Issuer"),
a statutory trust duly organized and existing under the laws of the State of
Delaware (the "State"), and ZIONS FIRST NATIONAL BANK, a national banking
association duly organized and operating under the laws of the United States of

the execution and delivery of this Indenture, which Indenture provides for the
payment of student loan asset-backed notes (the "Notes") and the payments to any

        SECTION 2.01. NOTE DETAILS. The Notes, together with the 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
appropriate reference thereto on the face of the Note.

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

        Each Note shall be dated the Date of 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 the U.S.
Dollar denominated Notes in an aggregate principal amount of $1,500,000,000, and
the London Paying Agent, which is hereby appointed as authenticating agent,
shall upon Issuer order authenticate and deliver the Non-U.S. Dollar denominated
Notes in the aggregate principal amount of (euro)420,521,000. The aggregate
principal amount of Notes Outstanding at any time may not exceed such amount
except as provided in Section 2.04 hereof. On each Spread Determination Date,
upon receipt of an Issuer Order, the Trustee shall deliver a revised Schedule A
for the Reset Rate Notes to the Custodians.

        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, except that during any Reset
Period when the Reset Rate Notes are denominated in a currency other than U.S.
Dollars, the Reset Rate Notes shall be issued in minimum denominations of the
applicable currency equivalent (approximately) of $100,000 and additional
increments of the applicable currency equivalent of $1,000 (which shall be
determined by reference to the exchange rate to be set forth in the related
Currency Swap Agreement); provided, that during any Reset Period when the Reset
Rate Notes are denominated in Pounds Sterling, the Reset Rate Notes shall be
issued in minimum denominations of (pound)100,000 and additional increments of
(pound)1,000, and, provided further, that during any Reset Period when the Reset
Rate Notes are denominated in Euros, the Reset Rate Notes shall be issued in

                                       29
<PAGE>

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

        Each Class of Notes (other than any Reset Rate Notes not denominated in
U.S. Dollars) will be represented by a book-entry note certificate ("U.S. Note
Certificate") deposited on the Date of Issuance with Zions First National Bank,
as custodian for DTC (the "DTC Custodian"), and registered in the name of "Cede
& Co." as initial nominee for DTC.

        The Reset Rate Notes not denominated in U.S. Dollars will be represented
by a book-entry note certificate ("Non-U.S. Note Certificate") deposited on the
Date of Issuance with HSBC Bank plc, as common depository for Euroclear and
Clearstream ("Non-U.S. Note Certificate Common Depository"), and registered in
the name of "HSBC Issuer Services Common Depositary Nominee (UK) Limited" being
the nominee name of HSBC Bank plc when acting as the Common Depositary.

        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, including
any Paying Agent. Upon surrender for transfer of any Note at the Principal
Office of the Trustee (or the London Paying Agent with respect to the Reset Rate
Notes which are denominated in Non-U.S. Dollars), 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
(or the London Paying Agent with respect to the Reset Rate Notes which are
denominated in Non-U.S. Dollars) 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.

        Notes may be exchanged at the Principal Office of the Trustee (or the
London Paying Agent with respect to the Reset Rate Notes which are denominated
in Non-U.S. Dollars) 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 (or the
London Paying Agent with respect to the Reset Rate Notes which are denominated
in Non-U.S. Dollars) 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 (or the London Paying Agent
with respect to the Reset Rate Notes which are denominated in Non-U.S. Dollars)
shall thereby be authorized to authenticate and deliver such fully registered
Note.

                                       30
<PAGE>

        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 (or the London Paying Agent with respect to the Reset Rate
Notes which are denominated in Non-U.S. Dollars) 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.

        On any Reset Date when the Reset Rate Notes are to be denominated in
U.S. Dollars during the immediately following Reset Period, the Outstanding
Amount of the Reset Rate Notes shall be allocated to the U.S. Note Certificate.
On any Reset Date when the Reset Rate Notes are to be denominated in a currency
other than U.S. Dollars during the immediately following Reset Period, the
Outstanding Amount of the Reset Rate Notes shall be allocated entirely to the
Non-U.S. Note Certificate.

        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 (or the London Paying Agent with respect to the Reset Rate Notes which
are denominated in Non-U.S. Dollars) shall authenticate and deliver, a
replacement Note of the same interest rate, maturity and denomination in lieu of
such lost, stolen, destroyed or mutilated Note or (b) if such lost, stolen,
destroyed or mutilated Note shall have matured within 15 days be due and
payable, in lieu of executing and delivering a new Note as aforesaid, the Issuer
may pay such Note. Any such new Note shall bear a number not contemporaneously
outstanding. The applicant for any such new Note may be required to pay all
taxes and governmental charges and all expenses and charges of the Issuer and of
the Trustee in connection with the issuance of such Note. All Notes shall be
held and owned upon the express condition that, to the extent permitted by law,
the foregoing conditions are exclusive with respect to the replacement and
payment of mutilated, destroyed, lost or stolen Notes, negotiable instruments or
other securities.

        SECTION 2.05. TRUSTEE'S AUTHENTICATION CERTIFICATE. The Trustee's (or
the London Paying Agent's with respect to the Reset Rate Notes which are
denominated in Non-U.S. Dollars) 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 (or the London Paying Agent with respect
to the Reset Rate Notes which are denominated in Non-U.S. Dollars); and such
certificate of the Trustee (or the London Paying Agent with respect to the Reset
Rate Notes which are denominated in Non-U.S. Dollars) upon any Note shall be
conclusive evidence and the only competent evidence that such Note has been
authenticated and delivered hereunder. The Trustee's (or the London Paying
Agent's with respect to the Reset Rate Notes which are denominated in Non-U.S.
Dollars) 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 (or the London Paying Agent with respect to the Reset Rate Notes which
are denominated in Non-U.S. Dollars), 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 (or the London
Paying Agent with respect to the Reset Rate Notes which are denominated in
Non-U.S. Dollars) 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 (or the London Paying Agent with respect to the Reset Rate Notes which
are denominated in Non-U.S. Dollars) and counterparts of a certificate of
destruction evidencing such cremation or other destruction shall be furnished by
the Trustee (or the London Paying Agent with respect to the Reset Rate Notes
which are denominated in Non-U.S. Dollars) to the Issuer.

        SECTION 2.07. TEMPORARY NOTES. Pending the preparation of definitive
Notes, the Issuer may execute and the Trustee (or the London Paying Agent with
respect to the Reset Rate Notes which are denominated in Non-U.S. Dollars) 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 (or the London Paying Agent with respect to the
Reset Rate Notes which are denominated in Non-U.S. Dollars) 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 (or the
London Paying Agent with respect to the Reset Rate Notes which are denominated
in Non-U.S. Dollars), and the Trustee (or the London Paying Agent with respect
to the Reset Rate Notes which are denominated in Non-U.S. Dollars) 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.

                                       32
<PAGE>

        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. BOOK-ENTRY NOTES. The Notes, upon original issuance, will
be issued in the form of typewritten Notes representing the Book-Entry Notes, to
be delivered to applicable initial Clearing Agency, by the Issuer, or on behalf
of the Issuer. Such Notes shall initially be registered on the Note Register in
the name of the nominee of each initial Clearing Agency, and no Noteholder shall
receive a definitive, fully registered note representing such Noteholder's
interest in such Note, except as provided in Section 2.11 hereof. Unless and
until Definitive Notes have been issued to Noteholders pursuant to Section 2.11
hereof:

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

                (b) the Trustee (or the London Paying Agent with respect to the
        Reset Rate Notes which are denominated in Non-U.S. Dollars), as
        registrar, and its respective directors, officers, employees and agents,
        may deal with the applicable Clearing Agency for all purposes (including
        the payment of principal of and interest and other amounts on the Notes)
        as the authorized representative of the Noteholders;

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

                (d) the rights of Noteholders shall be exercised only through
        the applicable Clearing Agency and shall be limited to those established
        by law and agreements between such Noteholders and the applicable
        Clearing Agency and/or the applicable Clearing Agency Participants
        pursuant to the Note Depository Agreements; and unless and until
        Definitive Notes are issued pursuant to Section 2.11 hereof, the initial
        Clearing Agencies will make book-entry transfers among the applicable
        Clearing Agency Participants and receive and transmit payments of
        principal of and interest and other amounts on the Notes to such
        applicable Clearing Agency Participants;

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

                (f) upon acquisition or transfer of a beneficial interest in any
        Book-Entry 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: (i) 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

                                       33
<PAGE>

        or Section 4975 of the Code which is not covered by a class or other
        applicable exemption and (ii) in the case of a Benefit Plan subject to a
        substantially similar federal, state, local or foreign 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. 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 2.11 hereof, the Trustee shall give all such notices and
communications specified herein to the applicable Clearing Agency.

        SECTION 2.11. DEFINITIVE NOTES. If (a) the Administrator advises the
Trustee in writing that a Clearing Agency (i) is closed for business for a
continuous period of 14 days (other than by reason of holiday, statutory or
otherwise), (ii) announces an intention to cease business permanently (or does
so and no alternative clearing system acceptable to the Trustee is then
available), or (iii) at any time, is unwilling or unable to continue as, or
ceases to be, a clearing agency registered under all applicable laws, and a
successor clearing agency which is registered as a clearing agency under all
applicable laws is not appointed by the Administrator within 90 days of such
event, (b) the Administrator at its option advises the Trustee in writing that
it elects to terminate the book-entry system through that Clearing Agency or (c)
after the occurrence of an Event of Default, Noteholders representing beneficial
interests aggregating at least a majority of the Outstanding Amount of the
applicable Notes advise the applicable Clearing Agency (which shall then notify
the Trustee) in writing that the continuation of a book-entry system through
such Clearing Agency is no longer in the best interests of such Noteholders,
then the Trustee shall cause such Clearing Agency to notify all Noteholders
cleared through such 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 a Clearing Agency, accompanied by registration instructions, the Issuer
shall execute and the Trustee (or the London Paying Agent with respect to the
Reset Rate Notes which are denominated in Non-U.S. Dollars) shall authenticate
the Definitive Notes in accordance with the instructions of such Clearing
Agency, which shall include, without limitation, the identity and payment
instructions for all Noteholders of the applicable Notes. 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 Noteholders.

        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 (ii) 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.

                                       34

        SECTION 2.12. PAYMENT OF PRINCIPAL AND INTEREST.

                (a) The Class A-1 Notes, the Class A-2 Notes, the Class A-3
        Notes, the Class A-4 Notes, the Class A-5 Notes and the Class B Notes
        shall accrue interest as provided in the forms of Class A-1 Notes, Class
        A-2 Notes, Class A-3 Notes, the Class A-4 Notes, the Class A-5 Notes and
        the Class B Notes set forth in Exhibits B-1, B-2, B-3, B-4, B-5 and B-7,
        respectively, hereto. The Class A-6 Notes shall accrue interest as
        provided in Appendix A hereto. Such interest shall be payable with
        respect to each Class of the Notes on each Quarterly Distribution Date
        as specified in Section 5.04(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
        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 2.11 hereof, with respect to Notes
        registered on the Record Date in the names of the nominees of the
        Clearing Agencies, payment shall be made by wire transfer in immediately
        available funds to the account designated by such nominees 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 Class A-1 Notes, the Class
        A-2 Notes, the Class A-3 Notes, the Class A-4 Notes, the Class A-5 Notes
        and the Class B 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. Interest on the Reset Rate Notes shall be computed
        pursuant to the applicable Day Count Basis. The terms of and definitions
        related to the Reset Rate Notes are found in Article I hereof and
        Appendix A hereto.

                (b) The principal of each Note shall be payable in installments
        on each Quarterly Distribution Date as provided in Section 5.04(c)
        hereof. Notwithstanding the foregoing, the entire unpaid principal
        amount of each Class of the Notes shall be due and payable, if not
        previously paid, on the Note Final Maturity Date for such Class of Notes
        and on the date on which an Event of Default shall have occurred and be
        continuing if the Trustee or the Registered Owners of the Notes
        representing not less than a majority of the Outstanding Amount of the
        Notes have declared the Notes to be immediately due and payable in the
        manner provided in Section 6.02 hereof. The Trustee shall notify the
        Person in whose name a Note is registered at the close of business on
        the Record Date preceding the 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.

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

                        (i) hold all sums held by it for the payment of amounts
                due with respect to the Notes or any Derivative Product in trust
                for the benefit of the Persons entitled thereto until such sums
                shall be paid to such Persons or otherwise disposed of as herein
                provided and pay such sums to such Persons as herein provided;

                        (ii) give the Trustee notice of any default by the
                Issuer of which it has actual knowledge (or any other obligor
                upon the Notes) in the making of any payment required to be made
                with respect to the Notes or any Derivative Product;

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

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

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

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

        SECTION 2.13. REDEMPTION OF THE NOTES.

                (a) MANDATORY REDEMPTION OF THE NOTES FROM SALE OF FINANCED
        ELIGIBLE LOANS. The Notes shall be subject to redemption from the
        proceeds of a sale of Financed Eligible Loans in accordance with Section
        10.03 or 10.04 hereof on any Quarterly Distribution Date.

                (b) MANDATORY REDEMPTION OF RESET RATE NOTES AND THE CLASS B
        NOTES. If there are no Class A Notes, other than the Reset Rate Notes,
        Outstanding and the Reset Rate Notes are bearing interest at the Failed

        in Section 2.13(a) of Appendix A hereto, the Reset Rate Notes and the

                                       36
<PAGE>

        Class B Notes are subject to redemption, in whole only, on any Quarterly
        Distribution Date on or after the date on which the Pool Balance is less
        than 25% of the Initial Pool Balance, at a redemption price equal to the
        principal amount thereof being redeemed, plus accrued interest, if any,
        due and payable on the Reset Rate Notes (as described in Appendix A
        hereto) and the Class B Notes to such Quarterly Distribution Date.

                (c) NOTICE OF REDEMPTION. Preferably five, but not less than two
        Business Days prior to the Quarterly Distribution Date on which the
        Notes are to be redeemed, the Trustee shall cause notice of any
        redemption pursuant to subsections (a), (b) or (c) of this Section to be
        given by mailing a copy of the notice by first-class mail to the
        Administrator and Registered Owners of the Notes at their address as the
        same shall last appear upon the registration books on such date;
        provided, however, that failure to give such notice, or any defect
        therein, shall not affect the validity of any proceedings for the
        reduction or redemption of such Notes.

                                  ARTICLE III

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

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

        SECTION 3.02. OTHER OBLIGATIONS. The Available Funds and other moneys,
Financed Eligible Loans, securities, evidences of indebtedness, interests,
rights and properties pledged under this Indenture are and will be owned by the
Issuer free and clear of any pledge, lien, charge or encumbrance thereon or with
respect thereto prior to, of equal rank with or subordinate to the respective
pledges created by this Indenture, except as otherwise expressly provided
herein, and all action on the part of the Issuer to that end has been duly and
validly taken. If any Financed Eligible Loan is found to have been subject to a
lien at the time such Financed Eligible Loan was acquired, the Issuer shall
cause such lien to be released, shall purchase such Financed Eligible Loan from
the Trust Estate for a purchase price equal to its principal amount plus any
unamortized premium, if any, and interest accrued thereon or shall replace such
Financed Eligible Loan with another Eligible Loan with substantially identical
characteristics which replacement Eligible Loan shall be free and clear of liens
at the time of such replacement. Except as otherwise provided herein, the Issuer
shall not create or voluntarily permit to be created any debt, lien or charge on
the Financed Eligible Loans which would be on a parity with, subordinate to, or
prior to the lien of this Indenture; shall not do or omit to do or suffer to be
done or omitted to be done any matter or things whatsoever whereby the lien of
this Indenture or the priority of such lien for the Obligations hereby secured
might or could be lost or impaired; and will pay or cause to be paid or will
make adequate provisions for the satisfaction and discharge of all lawful claims
and demands which if unpaid might by law be given precedence to or any equality
with this Indenture as a lien or charge upon the Financed Eligible Loans;

                                       37
<PAGE>

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. With respect to any Derivative Products, the Issuer shall cause
all Counterparty Payments and all other amounts payable to the Issuer from each
Counterparty to be deposited into the Collection Fund (with respect to all
Counterparty Payments received in U.S. Dollars) or the applicable Currency
Account (with respect to all Counterparty Payments received in any currency
other than U.S. Dollars). As promptly as possible upon the occurrence of an
Event of Default or Termination Event under any Derivative Product, the Issuer
shall hire or appoint a Broker in order to obtain a Replacement Transaction
according to the terms of the related Derivative Product, and such Broker shall
accept its appointment by a written assumption in a form acceptable to the
Issuer. In connection with any such appointment, the Issuer may make such
arrangements for the compensation of such Broker as it and such Broker shall
agree.

                                   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.

                                       38

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

        SECTION 4.03. FURTHER COVENANTS OF THE ISSUER.

                (a) The Issuer will cause financing statements and continuation
        statements with respect thereto at all times to be filed in the office

        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.

                                       39
<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.

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

        SECTION 4.04. ENFORCEMENT OF 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
        due the Issuer thereunder, including, without limitation, all principal
        and interest payments, and Guarantee payments which relate to any
        Financed Eligible Loans and cause the Master Servicer and each
        Subservicer to specify whether payments received by it represent
        principal or interest;

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

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

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

                (e) the Issuer agrees to give the Trustee and each Rating Agency
        prompt written notice of each default on the part of the Master Servicer
        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
        Servicer or a Subservicer under the Master Servicing Agreement or its
        related Subservicing Agreement without the written consent of the
        Trustee and the giving of written notice to each Rating Agency;

        Subservicer to deliver to the Trustee and the Issuer, on or before March
        30 of each year, beginning with March 30, 2007, a certificate stating
        that (i) a review of the activities of the Master Servicer and each
        Subservicer during the preceding calendar year and of its performance
        under the Master Servicing Agreement and its related Subservicing
        Agreement has been made under the supervision of the officer signing
        such certificate and (ii) to the best of such officers' knowledge, based
        on such review, the Master Servicer and such Subservicer has fulfilled
        all its obligations under the Master Servicing Agreement and its related
        Subservicing Agreement throughout such year, or, there has been a
        default in the fulfillment of any such obligation, specifying each such
        default known to such officer and the nature and stature thereof. The
        Issuer shall send copies of such annual certificate of the Master
        Servicer and each Subservicer to each Rating Agency; and

                (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
        any such amendment or modification will not materially adversely affect
        the rights or security of the Registered Owners.

        SECTION 4.05. PROCEDURES FOR TRANSFER OF FUNDS. In any instance where
this Indenture requires a transfer of funds or money from one Fund to another, a
transfer of ownership in investments or an undivided interest therein may be
made in any manner agreeable to the Issuer and the Trustee, and in the
calculation of the amount transferred, interest on the investment which has or
will accrue before the date the money is needed in the fund to which the
transfer is made shall not be taken into account or considered as money on hand
at the time of such transfer.

        SECTION 4.06. ADDITIONAL COVENANTS WITH RESPECT TO THE 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:

        Eligible Loans;

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

        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

                (d) the Issuer, or the Administrator on behalf of the Issuer,
        shall comply, and shall cause all of its officers, directors, employees

        for actions taken at the direction of the Issuer or the Administrator,
        except for negligence or willful misconduct in the performance of its
        express duties hereunder. The Trustee shall have no obligation to
        administer, service or collect the loans in the Trust Estate or to
        maintain or monitor the administration, servicing or collection of such
        loans; and

                (f) the Issuer, or the Administrator on behalf of the Issuer,
        shall cause each Financed Eligible Loan evidenced by a Master Promissory
        Note in the form mandated by Section 432(m)(1) of the 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.

                                       42
<PAGE>

               The Seller hereby authorizes the Trustee to file a UCC-1
               financing statement identifying the Seller as debtor and the
               Trustee as secured party and describing the MPN Loan sold
               pursuant to this Agreement. The preparation or filing of such
               UCC-1 financing statement is solely for additional protection of
               the Trustee's interest in the MPN Loans and shall not be deemed
               to contradict the express intent of the Seller and the Trustee
               that the transfer of MPN Loans under this Agreement is an
               absolute assignment of such MPN Loans and is not a transfer of
               such MPN Loans as security for a debt."

        The Trustee shall not be deemed to be the designated agent for the
purposes of this Section 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 London Paying Agency Agreement, the Custodian Agreement and the Investment
Agreement. The Issuer hereby directs the Eligible Lender Trustee to enter into
this Indenture, the Guarantee Agreements, the Custodian Agreement 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

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

Registered Owners.

                (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

                which it presently engages.

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

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

                                       44
<PAGE>

                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.

                                       45
<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 2006-1" 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.

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

                        (xvii) ABILITY TO PERFORM. There has been no material
                impairment in the ability of the Issuer to perform its
                obligations under this Indenture.

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

                        (xix) EVENT OF DEFAULT. No Event of Default has occurred
                and no event has occurred that, with the giving of notice, the
                passage of time, or both, would become an Event of Default.

                        (xx) ACQUISITION OF FINANCED ELIGIBLE LOANS LEGAL. The
                Issuer has complied with all applicable federal, state and local
                laws and regulations in connection with its acquisition of the
                Financed Eligible Loans from the Seller.

                        (xxi) NO MATERIAL MISSTATEMENTS OR OMISSIONS. No
                information, certificate of an officer, statement furnished in
                writing or report delivered to the Trustee, the Master Servicer,
                a Subservicer or any Registered Owner by the Issuer contains any
                untrue statement of a material fact or omits a material fact
                necessary to make such information, certificate, statement or
                report not misleading.

        (b)     The Issuer will not:

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

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

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

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

                                       47
<PAGE>

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

                        (vi) permit the lien of this Indenture not to constitute

                Estate;

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

        warranties as to the Trust Estate which is granted to the Trustee
        hereunder on such date, on which the Trustee relies in accepting the
        Trust Estate. Such representations and warranties shall survive the
        grant of the Trust Estate to the Trustee pursuant to this Indenture:

                                       48
<PAGE>

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

                        (ii) GRANT. It is the intention of the Issuer that the
                transfer herein contemplated constitutes a grant of the Financed
                Eligible Loans to the Trustee.

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

                        (iv) TRANSFER NOT SUBJECT TO BULK TRANSFER ACT. Each
                grant of the Financed Eligible Loans by the Issuer pursuant to
                this Indenture is not subject to the bulk transfer act or any

                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.

                conditions and covenants of this Indenture as may be required

                (c) Not later than the second Business Day (or the fifth
        Business Day with respect to any Reset Period when the Issuer is then
        party to a Currency Swap Agreement) preceding each Quarterly

                                       51
<PAGE>

        Quarterly Distribution Date Certificate"), or containing such
        information as the Commission may from time to time by rules or
        regulations prescribe, to the Trustee. The Trustee shall provide a copy
        of any Administrator's Quarterly Distribution Date Certificate to any

        the prescribed timing, rules and regulations of the Commission.

        SECTION 4.16. STATEMENT AS TO COMPLIANCE. The Issuer will deliver to the
Trustee, within 120 days after the end of each fiscal year, a brief certificate
from an Authorized Representative including (a) a current list of the Authorized
Representatives, and (b) a statement indicating whether or not to the knowledge
of the signers thereof the Issuer is in compliance with all conditions and
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 Issuer.

                (b) The Higher Education Act deems the Financed Eligible Loans
        to constitute accounts within the meaning of the applicable UCC as in
        effect in the State of Delaware 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 that those
        granted pursuant to this Indenture.

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

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

                                       52
<PAGE>

                (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 Subservicers, if any, to take all steps
        necessary and appropriate, to maintain the perfection and priority of
        the Trustee's security interest in the Financed Eligible Loans.

        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 falls below the Initial Parity Ratio, 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

                                       53
<PAGE>

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. On each Quarterly Distribution
Date, the Issuer will provide to the Trustee, and the Trustee will forward, or
cause to be forwarded, to each Registered Owner, a statement setting forth
information with respect to the Notes on such Quarterly Distribution Date and
the Student Loans as of the end of the preceding Collection Period, including
the following:

                (a) the amount of principal payments made with respect to each
        Class of the Notes on such Quarterly Distribution Date;

                (b) the amount of interest payments made with respect to each
        Class of the Notes on such Quarterly Distribution Date;

                (c) the Pool Balance as of the end of the preceding Collection
        Period;

                (d) the Outstanding Amount of each Class of the Notes on such
        Quarterly Distribution Date;

                (e) the interest rate for each Class of the Notes on such
        Quarterly Distribution Date;

                (f) the number and Principal Balance of Financed Eligible Loans
        that are delinquent or for which claims have been made with a Guaranty
        Agency as of the end of the preceding Collection Period; and

                (g) the Outstanding Amount of the Notes on such Quarterly
        Distribution Date.

                                      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 (or with respect to the Currency Fund, the London Paying Agent) for
the benefit of the Registered Owners (and the Remarketing Agents with respect to
the Remarketing Fee Fund):

                (a) Acquisition Fund, including a Prefunding Account and a Costs
        of Issuance Account therein;

                (b) Capitalized Interest Fund;

                (c) Collection Fund;

                (d) Reserve Fund;

                                       54
<PAGE>

                (e) Remarketing Fee Fund;

                (f) Supplemental Interest Fund;

                (g) Accumulation Fund, including the Class A-6 Accumulation
        Account established therein;

                (h) Currency Fund, including any Currency Accounts established
        therein; and

                (i) Collateral Fund, including any Currency Swap Agreement
        Collateral Account established therein.

        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 an amount equal to
$1,972,080,238. There shall be deposited into the Prefunding Account of the
Acquisition Fund moneys from the proceeds of the Notes deposited to the
Acquisition Fund, an amount equal to $516,792,846 and any amounts transferred to
the Acquisition Fund from the Capitalized Interest Fund pursuant to Section 5.03
hereof. There shall be deposited into the Costs of Issuance Account of the
Acquisition Fund from the proceeds of the Notes deposited to the Acquisition
Fund, an amount equal to $998,900. 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 Costs of Issuance Account of the Acquisition
Fund shall be used, upon Issuer Order, to pay costs of issuance of the Notes,
including the costs related to the purchase of one or more Derivative Products,
if any. 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 (including
any "add-on consolidation loans") at a price not in excess of 100% of the
outstanding principal balance of such Eligible Loans, plus accrued interest. Any
such Issuer Order or Eligible Loan Acquisition Certificate shall state that such
proposed use of moneys in the Prefunding Account of the Acquisition Fund 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 5.04(b) (other than transfers to fund "add-on
consolidation loans" or repurchase student loans from the Master Servicer, and
Subservicer or any Guaranty Agency as described in clause (a)(i) and (iii) of
the definition of Available Funds) and 5.04(c)(i) through (v) and (x) hereof
(other than Termination Payments), then the Administrator shall instruct the
Trustee in writing to withdraw from the Acquisition Fund (first from the
Prefunding Account and second from the Costs of Issuance 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 to the extent moneys are not
available to make such transfers from the Capitalized Interest Fund pursuant to

                                       55
<PAGE>

Section 5.03 hereof. Notwithstanding the foregoing, if any funds or moneys
remain in the Costs of Issuance Account of the Acquisition Fund on the Quarterly
Distribution Date in May of 2006, then the Trustee shall, without direction from
or notice to the Issuer, transfer all such remaining moneys or funds to the
Prefunding Account of the Acquisition Fund on the Quarterly Distribution Date in
May of 2006. Notwithstanding the foregoing, if any funds or moneys remain in the
Prefunding Account of the Acquisition Fund on the Quarterly Distribution Date in
February of 2007, then the Trustee shall, without direction from or notice to
the Issuer, transfer all such remaining moneys or funds to the Collection Fund
on the Quarterly Distribution Date in February of 2007.

        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 5.12, 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) when the Issuer
does not have sufficient moneys in the Collection Fund to fund any required
"add-on consolidation loan" (in which case the Issuer may sell the Financed
Eligible Loan to which such required "add-on consolidation loan" relates),
Financed Eligible Loans shall not be sold, transferred or otherwise disposed of
by the Issuer through the Trustee free from the lien of this Indenture while any
of the Class A Notes are Outstanding. In addition, if necessary for
administrative purposes or if requested by the borrower corresponding to such
Financed Eligible Loan, the Issuer may substitute another Eligible Loan for an
existing Financed Eligible Loan if the substituted Eligible Loan has
characteristics (including principal amount, maturity date and interest rate)
which are substantially similar to the characteristics of the substituted
Financed Eligible Loan, and the collective amount of all such substitutions does
not exceed $10,000,000. 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 hereby certifies, upon which the Trustee may
conclusively rely, that any Financed Eligible Loan substituted pursuant to this
Indenture shall have characteristics (including principal amount, maturity date
and interest rate) which are substantially similar to the characteristics of the
substituted Financed Eligible Loan, and the collective amount of all such
substitutions does not exceed $10,000,000. 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. CAPITALIZED INTEREST FUND. There shall be deposited into
the Capitalized Interest Fund moneys from proceeds of the Notes in an amount
equal to $19,000.,000.

        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 5.04(b) (other than
transfers to fund "add-on consolidation loans" or repurchase student loans from
the Master Servicer, any Subservicer or any Guaranty Agency as described in
clause (a)(i) and (iii) of the definition of Available Funds) and 5.04(c)(i)
through (v) and (x) hereof (other than Termination Payments), then the
Administrator shall instruct the Trustee in writing to withdraw from the
Capitalized Interest 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. On the Quarterly Distribution Date

        written instructions of the Administrator described in this Indenture
        with no further duty to examine or determine the information contained
        in any Administrator's Certificate or Issuer Order.

                (b) PAYMENTS ON MONTHLY SERVICING PAYMENT DATES. The
        Administrator shall instruct the Trustee in writing no later than the
        second Business Day preceding each Monthly Servicing Payment Date that
        is not a Quarterly Distribution Date (based on the information contained
        in a certificate of the Administrator (in the form set forth as Exhibit
        C hereto) and the related Servicer's Report, if applicable) to
        distribute to the Master Servicer, on such Monthly Servicing Payment

        pursuant to Section 5.02 hereof and the Reserve Fund pursuant to Section
        5.05(b) and (c) hereof), the Servicing Fees due with respect to the

        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 amounts described in clause (a)(i),
        (ii) and (iii) of the definition of Available Funds.

                (c) PAYMENTS ON QUARTERLY DISTRIBUTION DATES. The Administrator
        shall instruct the Trustee in writing no later than the second Business
        Day preceding each Quarterly Distribution Date (or the fifth Business
        Day with respect to any Reset Period when the Issuer is then party to a
        Currency Swap Agreement) (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 Capitalized Interest
        Fund pursuant to Section 5.03 hereof, the Acquisition Fund pursuant to
        Section 5.02 hereof and the Reserve Fund pursuant to Section 5.05(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, the Capitalized
        Interest 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):

                        (i) to pay to the Master Servicer, the Trustee and the
                Delaware Trustee, pro rata, based on amounts owed to each such
                party, without preference or priority of any kind, the Servicing

                Servicing Payment Date), the Trustee Fee and the Delaware
                Trustee Fee, respectively, due on such Quarterly Distribution
                Date, in each case, together with such fees remaining unpaid

                Fee due on such Quarterly Distribution Date and all unpaid
                Administration Fees from prior Quarterly Distribution Dates;

                Class, the portion of the Class A Noteholders' Interest
                Distribution Amount payable to such Class on such Quarterly

                Distribution Date (other than to the Noteholders of the Reset
                Rate Notes if a Currency Swap Agreement with respect to interest
                payments to be made to the Noteholders of the Reset Rate Notes
                is then in effect) and (B) to pay the Counterparty under a
                Derivative Product (including any Currency Swap Agreement with
                respect to the Reset Rate Notes), any Issuer Derivative Payments
                owed to such Counterparty on such Quarterly Distribution Date
                (excluding Termination Payments other than Priority Termination
                Payments), pro rata, based on amounts owed to each such party,
                without preference or priority of any kind;

                        (v) to pay to the Class B Noteholders, the portion of
                the Class B Noteholders' Interest Distribution Amount payable on

                kind;

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

                        (vii) to the Class A Noteholders, the Class A Principal
                Distribution Amount in the following order:

                                (A) to pay to the Class A-1 Noteholders until
                        the Class A-1 Notes have been paid in full;

                                (B) to pay to the Class A-2 Noteholders until
                        the Class A-2 Notes have been paid in full;

                                (C) to pay to the Class A-3 Noteholders until

                                (D) to pay to the Class A-4 Noteholders until
                        the Class A-4 Notes have been paid in full;

                                (E) to pay to the Class A-5 Noteholders until
                        the Class A-5 Notes have been paid in full; and

                                (F) to pay to the Class A-6 Noteholders until
                        the Class A-6 Notes have been paid in full; provided,
                        however, (I) if the Class A-6 Notes are then denominated
                        in U.S. Dollars and are then structured not to receive a
                        payment of principal until the end of the related Reset
                        Period, principal payments will be allocated to the
                        Class A-6 Accumulation Account, until amounts on deposit
                        therein are sufficient to reduce the Outstanding Amount
                        of the Class A-6 Notes to zero, and (II) if the Class
                        A-6 Notes are in a Foreign Exchange Mode, such principal
                        payments either (x) will be made to the related Currency
                        Swap Counterparty or Counterparties or (y) if the Class
                        A-6 Notes are then structured not to receive a payment
                        of principal until the end of the related Reset Period,
                        such payments will be allocated to the Class A-6
                        Accumulation Account, until the U.S. Dollar Equivalent

<PAGE>

                        Principal Amount of such Class A-6 Notes has been
                        distributed to the related Currency Swap Counterparty or
                        Counterparties or allocated to the Class A-6
                        Accumulation Account; and provided further that for
                        purposes of this clause (F), the Outstanding Amount of
                        the Class A-6 Notes will be deemed to have been reduced
                        by any amounts (less any investment earnings) on deposit
                        in the Class A-6 Accumulation Account;

                        (viii) on each Quarterly Distribution Date to transfer
                to the Supplemental Interest Fund, an amount equal to the
                Supplemental Interest Deposit Amount;

                        (ix) on and after the Stepdown Date, and provided that
                no Trigger Event is in effect on such Quarterly Distribution
                Date, to the Class B Noteholders, the Class B Principal
                Distribution Amount;

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

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

                        (xii) to pay to the Counterparties, pro rata, without
                preference or priority of any kind, any accrued and unpaid
                Termination Payments due to each such Counterparty under the
                applicable Derivative Product;

                        (xiii) to the Administrator to reimburse it for any
                payments made by it to the Remarketing Agents pursuant to the
                Remarketing Agreement;

                        (xiv) 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 Class A-1 Notes,
                the Class A-2 Notes, the Class A-3 Notes, the Class A-4 Notes,
                the Class A-5 Notes, the Class A-6 Notes and the Class B Notes
                then Outstanding, to the Noteholders in the same order and
                priority as is set forth in clauses (vii)(A) through (F) and
                (ix) of this subsection (c) until the principal amount of the
                Notes is paid in full; and

                        (xv) subject to the remaining provisions of this
                Section, to pay to the Depositor any remaining funds.

               Amounts that would be paid to each Currency Swap Counterparty
        pursuant to clauses (iv), (vii)(F) or (xii) of this subsection (c), with
        respect to payments of interest on the Reset Rate Notes if the Reset
        Rate Notes bear a fixed rate of interest or with respect to payments of
        principal on the Reset Rate Notes then in a Foreign Exchange Mode, will
        be determined on or before the fifth Business Day preceding each
        Quarterly Distribution Date and will be paid by the Issuer as set forth
        in the applicable Swap Agreement (or, with respect to a Quarterly
        Distribution Date that coincides with a Reset Date resulting in a
        successful remarketing of the Reset Rate Notes if the Reset Rate Notes
        are then in a Foreign Exchange Mode, payments under the related Swap
        Agreement will be made on such Quarterly Distribution Date).

                                       60
<PAGE>

               Amounts properly distributed to the Depositor pursuant to clause
        (vi) or (xv) of this subsection (c) shall be deemed released from the
        Trust Estate and the security interest therein granted to the Trustee,
        and the Depositor shall in no event thereafter be required to refund any
        such distributed amounts.

               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, the Capitalized Interest
        Fund and the Reserve Fund, and such payments or deposits were made with
        other Available Funds on deposit in the Collection Fund.

               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
        each Date of Issuance, unless the Issuer, after furnishing each Rating
        Agency with revised cash flows, shall have received a Rating
        Confirmation.

               In the event that a Termination Payment is owed by the Issuer to
        any Counterparty and a Replacement Transaction is procured by the Issuer
        under which the replacement Counterparty makes a payment to the Issuer,
        the Issuer will pay that amount directly to the original Counterparty to
        the extent that a Termination Payment is owed by the Issuer to that Swap
        Counterparty. If after making that payment, the original Counterparty is
        still owed a payment, then the remaining amount will be paid as set
        forth in clause (xii) of this subsection (c).

               If a Currency Swap Agreement terminates, amounts that would have
        otherwise been paid to the related Currency Swap Counterparty under the
        related Currency Swap Agreement will be used to make payments to the
        Noteholders of the Reset Rate Notes in an amount in Euros, Pounds
        Sterling or any other applicable non-U.S. Dollar currency equal to the
        payment that would have been made by the related Currency Swap
        Counterparty to the Issuer. If this occurs, the Administrator, on behalf
        of the Issuer, will exchange, or will instruct the Trustee to exchange,
        U.S. Dollars for Euros, Pounds Sterling or any other applicable non-U.S.
        Dollar currency in order to make distributions to the Noteholders of the
        Reset Rate Notes.

        SECTION 5.05. RESERVE FUND.

                (a) On the Date of Issuance, the Trustee shall deposit
        $4,918,662 into the Reserve Fund. Thereafter, the Trustee shall transfer
        to the Reserve Fund from the Collection Fund all amounts designated for
        transfer thereto pursuant to Section 5.04(c)(x) hereof.

                                       61
<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 5.04(b) (other than transfers to fund "add-on consolidation
        loans" or repurchase student loans from the Master Servicer, any
        Subservicer or any Guaranty Agency as described in clause (a)(i) and
        (iii) of the definition of Available Funds) and 5.04(c)(i) through
        (c)(v) hereof (other than Termination Payments), 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 Capitalized Interest Fund
        pursuant to Section 5.03 hereof or 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 Fee, 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 5.06. REMARKETING FEE FUND.

                (a) DEPOSITS TO THE REMARKETING FEE FUND. On each Quarterly
        Distribution Date, an amount up to the Quarterly Funding Amount shall be
        deposited to the Remarketing Fee Fund pursuant to Section 5.04(c)(ii)
        hereof.

                (b) USE OF MONEYS IN THE REMARKETING FEE FUND. Amounts on
        deposit in the Remarketing Fee Fund shall be used to pay the Remarketing
        Fees due on the Reset Rate Notes on the Reset Date. If the amount on
        deposit in the Remarketing Fee Fund on any Quarterly Distribution Date,
        after the payment of any Remarketing Fees due on such Quarterly
        Distribution Date, exceeds the sum of the Reset Period Target Amounts,
        the Issuer may direct the Trustee to transfer such excess to the
        Collection Fund on such Quarterly Distribution Date. In the event that
        the fees owed to any Remarketing Agent on a Reset Date exceeds the
        amount then on deposit for such purposes in the Remarketing Fee Fund,
        such shortfall shall be paid on future Quarterly Distribution Dates. The
        Issuer shall also be responsible for certain costs and expenses to the
        extent set forth in Section 3 of the Remarketing Agreement, which shall
        be paid on each Quarterly Distribution Date from the Collection Fund
        pursuant to Section 5.04(c)(ii) hereof to the extent funds are available
        therefor. If on any Quarterly Distribution Date a Class A-1 Note
        Interest Shortfall, a Class A-2 Note Interest Shortfall, a Class A-3
        Note Interest Shortfall, a Class A-4 Note Interest Shortfall, a Class
        A-5 Note Interest Shortfall or a Class A-6 Note Interest Shortfall would
        exist, or if on the Note Final Maturity Date for any Class of the Class
        A Notes, Available Funds would not be sufficient to reduce the principal
        balance of that Class of the Class A Notes to zero, the amount of the a
        Class A-1 Note Interest Shortfall, a Class A-2 Note Interest Shortfall,
        a Class A-3 Note Interest Shortfall, a Class A-4 Note Interest
        Shortfall, a Class A-5 Note Interest Shortfall or a Class A-6 Note
        Interest Shortfall or principal deficiency, as applicable, to the extent
        sums are on deposit in the Remarketing Fee Fund, shall be withdrawn from
        the Remarketing Fee Fund and used for payment of interest or principal
        on the Class A Notes.

        SECTION 5.07. SUPPLEMENTAL INTEREST FUND.

                (a) DEPOSITS TO THE SUPPLEMENTAL INTEREST FUND. Amounts
        transferred from the Collection Fund pursuant to Section 5.04(c)(viii)
        hereof representing a Supplemental Interest Deposit Amount shall be
        deposited to the Supplemental Interest Fund.

                (b) USE OF MONEYS IN THE SUPPLEMENTAL INTEREST FUND. All amounts
        on deposit in any Account of the Supplemental Interest Fund shall be
        transferred to the Collection Fund on each Quarterly Distribution Date.

        SECTION 5.08. ACCUMULATION FUND.

                (a) If the Class A-6 Notes are structured to receive a payment
        of principal only at the end of the related Reset Period, amounts
        transferred pursuant to subsection (c)(vii) of Section 5.04 hereof to
        pay principal on the Class A-6 Notes shall be deposited to the Class A-6
        Accumulation Account within the Accumulation Fund.

                                       63
<PAGE>

                (b) If the Class A-6 Notes are denominated in U.S. Dollars and
        are structured during the then-current Reset Period not to receive a
        payment of principal until the end of the related Reset Period, the
        Administrator shall instruct the Trustee in writing no later than one
        Business Day preceding each Quarterly Distribution Date that is also a
        Reset Date, to withdraw from the Class A-6 Accumulation Account on such
        Quarterly Distribution Date (after any additional allocations of
        principal are made to the Class A-6 Accumulation Account on such
        Quarterly Distribution Date) the amount (less any investment earnings)
        on deposit in the Class A-6 Accumulation Account and distribute (by 1:00
        p.m. (New York time) on the related Quarterly Distribution Date) such
        amounts to the Noteholders of the Class A-6 Notes as of the immediately
        current Record Date, pro rata, as a payment of principal as set forth in
        Section 5.04(c)(vii) hereof. If the Class A-6 Notes are in a Foreign
        Exchange Mode and are structured during the then-current Reset Period
        not to receive a payment of principal until the end of the related Reset
        Period and a Currency Swap Agreement is in effect for the Class A-6
        Notes, the Administrator shall instruct the Trustee in writing no later
        than five Business Day preceding each Quarterly Distribution Date that
        is also a Reset Date, to withdraw from the Class A-6 Accumulation
        Account on such Quarterly Distribution Date (after any additional
        allocations of principal are made to that account on such Quarterly
        Distribution Date) the amount (less any investment earnings) on deposit
        in the Class A-6 Accumulation Account and deliver such amounts to the
        related Currency Swap Counterparty or Counterparties in exchange for the
        amount of the applicable non-U.S. Dollar currency, determined using the
        exchange rate set forth in the related Currency Swap Agreement, for
        payment to the Noteholders of the Class A-6 Notes as of the immediately
        preceding Record Date, pro rata, as a payment of principal as set forth
        in Section 5.04(c)(vii) hereof. Amounts (less any investment earnings)
        on deposit in the Class A-6 Accumulation Account may be used only to pay
        principal on the Class A-6 Notes (or to the related Currency Swap
        Counterparty or Counterparties) and for no other purpose. If no Currency
        Swap Agreement is in effect for the Class A-6 Notes, such payment shall
        be made as set forth in Section 5.04 hereof.

                (c) In the event that on any Quarterly Distribution Date the
        amount (less any Investment Earnings) on deposit for the Class A-6 Notes
        in the Class A-6 Accumulation Account, including amounts deposited on
        that Quarterly Distribution Date, would equal the Outstanding Amount of
        the Class A-6 Notes, then no additional amounts will be deposited into
        the Class A-6 Accumulation Account and all amounts therein, less any
        investment earnings, will be distributed on the next related Reset Date,
        pursuant to subsection (b) of this Section, and the Outstanding Amount
        of the Class A-6 Notes will be reduced to zero.

        SECTION 5.09. CURRENCY FUND.

                (a) On the Date of Issuance, with respect to the Class A-6 Notes
        for the initial Reset Period, and on each Reset Date when the Reset Rate
        Notes are reset to be denominated in a currency other than U.S. Dollars
        during the next Reset Period, the Issuer shall establish and maintain a
        Currency Account for the Reset Rate Notes.

                                       64
<PAGE>

                (b) Any payments in the related currency received from any
        Currency Swap Counterparty will be deposited into the related Currency
        Account for the benefit of the Noteholders of the Reset Rate Notes.

                (c) The Administrator shall instruct the Trustee to direct the
        London Paying Agent in writing no later than the Business Day preceding
        each Quarterly Distribution Date to distribute the Class A-6
        Noteholders' Interest Distribution Amount from amounts on deposit in the
        applicable Currency Account to the Noteholders of the Reset Rate Notes
        by 10:00 a.m. (London time) on the related Quarterly Distribution Date;
        provided, however, that with respect to any Quarterly Distribution Date
        that coincides with a Reset Date when the Reset Rate Notes are then in a
        Foreign Exchange Mode, the Administrator will instruct the London Paying
        Agent to distribute the amounts in the applicable Currency Account to
        the Noteholders of the Reset Rate Notes by 3:30 p.m. (London time) on
        the date the London Paying Agent receives such amounts (unless the
        amounts are not received prior to 10:00 a.m. (London time), then such
        distribution shall be on the next Business Day). If the related Currency
        Swap Agreement is not in effect, the Administrator shall cause U.S.
        Dollars to be converted into such other applicable non-U.S. Dollar
        currency in amounts sufficient to make the distributions specified in
        this Indenture.

        SECTION 5.10. COLLATERAL FUND. In the event that pursuant to the terms
of any applicable Currency Swap Agreement, a related Currency Swap Counterparty
(or its credit support provider) is required to deposit cash or securities as
collateral to secure its obligations ("Swap Collateral"), the Trustee shall
establish and maintain one or more Accounts within the Collateral Fund in the
name of the Trustee for the benefit of the Issuer and the Noteholders (each a
"Currency Swap Agreement Collateral Account") upon written notice from the
Issuer. All sums on deposit and securities held in any Currency Swap Agreement
Collateral Account shall be used only for the purposes set forth in the related
credit support agreement to be entered into between the Issuer and the related
Currency Swap Counterparty (a "Credit Support Agreement"). Amounts on deposit in
any Currency Swap Agreement Collateral Account may be invested in Investment
Securities at the written direction of the related Swap Counterparty and on each
Quarterly Distribution Date, all investment earnings actually received by the
Trustee on amounts on deposit in a Currency Swap Agreement Collateral Account or
on securities held by the Trustee as Swap Collateral shall be paid directly to
the related Swap Counterparty and not become part of Available Funds in
accordance with the terms of the Credit Support Agreement. All amounts deposited
in a Currency Swap Agreement Collateral Account shall be paid to the Issuer (and
become part of Available Funds on the related Quarterly Distribution Date) or
returned to the related Swap Counterparty, from time to time, in accordance with
the provisions set forth in the related Credit Support Agreement. The Trustee
shall be entitled to conclusively rely on the written instructions of the Issuer
or the Administrator with respect to sums on deposit in the Collateral Fund and
any Currency Swap Agreement Collateral Account without responsibility to know or
determine the purpose or provisioons set forth in the related Collateral Support
Agreement.

        SECTION 5.11. 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

                                       65
<PAGE>

the Trustee hereunder (other than any Currency Account) as directed in writing
(or orally, confirmed in writing) by an Authorized Representative of the Issuer,
to the fullest extent practicable and reasonable, in Investment Securities which
shall mature or be redeemed at the option of the holder prior to the respective
dates when the money held for the credit of such Fund or Account will be
required for the purposes intended. In the absence of any such direction and to
the extent practicable, the Trustee shall invest amounts held hereunder in those
Investment Securities described in clause (k) of the definition of the
Investment Securities. All such investments shall be held by (or by any
custodian on behalf of) the Trustee for the benefit of the Issuer; provided that
on the Business Day preceding each Quarterly Distribution Date all interest and
other investment income collected (net of losses and investment expenses) on
funds on deposit therein (other than in any Currency Account) shall be deposited
into the Collection Fund and shall be deemed to constitute a portion of the
Available Funds. The Trustee and the Issuer hereby agree that unless an Event of
Default shall have occurred hereunder, the Issuer acting by and through an
Authorized Representative shall be entitled to, and shall, provide written
direction or oral direction confirmed in writing to the Trustee with respect to
any discretionary acts required or permitted of the Trustee under any Investment
Securities and the Trustee shall not take such discretionary acts without such
written direction.

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

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

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

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

        SECTION 5.12. 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, each Remarketing Agent, 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 to (i) the
        Seller in accordance with the Student Loan Purchase Agreement; (ii) the
        Master Servicer or a Subservicer in accordance with the Master Servicing
        Agreement or the applicable Subservicing Agreement; and (iii) another
        eligible lender holding one or more serial loans with respect to such
        Financed Eligible Loan, in accordance with the Master Servicing
        Agreement or the applicable Subservicing Agreement, and each Registered
        Owner, by the acceptance of a Note, consents to any such release.

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

        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

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:

        Derivative Products (excluding all Termination Payments other than
        Priority Termination Payments), (ii) to the Class A Noteholders (other

        any other unpaid Issuer Derivative Payments;

               NINTH, to the Remarketing Agents, any due and unpaid Remarketing
        Fees payable by the Issuer to the extent not previously paid from
        amounts on deposit in the Remarketing Fee Fund;

               TENTH, sequentially, first to the Remarketing Agents, and second
        to the Administrator for any advances made on behalf of the Issuer, in
        each case, for payment of certain costs and expenses as set forth in
        Section 3 of the Remarketing Agreement in connection with the
        remarketing of the Reset Rate Notes not previously reimbursed by the
        Issuer; and

               ELEVENTH, to the Master Servicer, for any unpaid Carryover

               TWELFTH, to the Issuer.

        If the Issuer has entered into a Currency Swap Agreement and such
Currency Swap Agreement terminates, amounts that would have otherwise been paid
to the related Currency Swap Counterparty (other than amounts payable as a
Termination Payment thereunder) will be used to make payments to the Reset Rate
Noteholders in an amount in the applicable non-U.S. Dollar currency, equal to
the payment that the related Currency Swap Counterparty would have made. If this
occurs, the Issuer will exchange U.S. Dollars for the applicable non-U.S. Dollar
currency in order to make distributions on the Reset Rate Notes.

        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.

        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.

        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

                        (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,
                the Delaware Trustee, any Remarketing Agent and their agents and
                counsel; and

                                       72
<PAGE>

                (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 its Note Final Maturity Date,

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

        If the Issuer fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as Trustee of an express trust, may upon receiving
indemnification satisfactory to the Trustee institute a judicial proceeding for
the collection of the sums so due and unpaid, may prosecute such proceeding to
judgment or final decree, and may enforce the same against the Issuer or any
other obligor upon such Notes of such 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.

        If an Event of Default with respect to Notes occurs and is continuing,
the Trustee may, after being indemnified to its satisfaction and in its
discretion, proceed to protect and enforce its rights and the rights of the
Registered Owners of Notes 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.

                                       73
<PAGE>

        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.

                                       74
<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.

                                   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.

                                       75
<PAGE>

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

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

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

        SECTION 7.03. AS TO FILING OF INDENTURE. The Trustee shall be under no
duty (a) to file or record, or cause to be filed or recorded, this Indenture or
any instrument supplemental hereto, (b) 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
not be liable for failure of the Issuer to pay any tax or taxes in respect of
such property, or any part thereof, or the income therefrom or otherwise, nor
shall the Trustee be under any duty in respect of any tax which may be assessed
against it or the Registered Owners in respect of such property or pledged to
the Trust Estate. The Trustee agrees to prepare, request that the Issuer execute
(if such execution is necessary for any such filing) and file in a timely manner
(if received from the Issuer in a timely manner) with any necessary execution by
the Issuer, the continuation statements referred to herein; provided, that the
Trustee shall have no responsibility for the sufficiency, adequacy or priority
of any initial filing and in the absence of written notice to the contrary by
the Issuer or other Authorized Representative, may rely and shall be protected
in relying on all information and exhibits in such initial filings for the
purposes of any continuation statements.

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

                                       76
<PAGE>

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

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

                                       77
<PAGE>

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

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

        SECTION 7.07. COMPENSATION OF TRUSTEE. Except as otherwise expressly
provided herein, all advances, counsel fees (including without limitation
allocated fees of in-house counsel) and other expenses reasonably made or
incurred by the Trustee in and about the execution and administration of the
trust hereby created and reasonable compensation to the Trustee for its services
in the premises shall be paid by the Issuer. The compensation of the Trustee
shall not be limited to or by any provision of law in regard to the compensation
of trustees of an express trust. The Trustee shall not change the 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).

                                       78
<PAGE>

        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.

        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 of the
Issuer, or an authorized officer of the successor Trustee, execute, acknowledge
and deliver such instruments of conveyance and further assurance and do such
other things as may reasonably be required for more fully and certainly vesting
and confirming in such successor Trustee all the right, title and interest of
the Trustee which it succeeds, in and to the Trust Estate and such rights,
powers, trusts, duties and obligations, and the Trustee ceasing to act also,
upon like request, pay over, assign and deliver to the successor Trustee any
money or other property or rights subject to the lien of this Indenture,
including any pledged securities which may then be in its possession. Should any
deed or instrument in writing from the Issuer be required by the successor
Trustee for more fully and certainly vesting in and confirming to such new
Trustee such estate, properties, rights, powers and duties, any and all such
deeds and instruments in writing shall on request be executed, acknowledged and
delivered by the Issuer.

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

        SECTION 7.13. ADDITIONAL COVENANTS BY THE TRUSTEE TO CONFORM TO THE
HIGHER EDUCATION ACT. The Trustee covenants that it will at all times be an
Eligible Lender under the Higher Education Act so long as such designation is
necessary, as determined by the Issuer, to maintain the guarantees and federal
benefits under the Higher Education Act with respect to the Financed Eligible
Loans, that it will acquire Eligible Loans originated under the Higher Education
Act in its capacity as an Eligible Lender and that it will not knowingly dispose
of or deliver any Financed Eligible Loans originated under the 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:

                (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 of the Issuer, the Secretary or the Guaranty Agency, use
        its reasonable efforts to cause this Indenture to be amended (in
        accordance with Section 8.01 hereof) if the 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:

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

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

        SECTION 7.20. RECEIPT OF FUNDS FROM 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.

        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

                                       83
<PAGE>

                (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.

                                  ARTICLE VIII

                             SUPPLEMENTAL INDENTURES

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

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

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

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

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

                                       84
<PAGE>

                (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, the Master
        Servicer or a 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 the Higher
        Education Act, the Regulations or the Code and the regulations
        promulgated thereunder;

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

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

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

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

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

        SECTION 8.02. SUPPLEMENTAL INDENTURES REQUIRING CONSENT OF REGISTERED
OWNERS. Exclusive of Supplemental Indentures covered by Section 8.01 hereof and
subject to the terms and provisions contained in this Section, and not
otherwise, the Registered Owners of not less than a majority of the collective
aggregate principal amount of the Obligations then Outstanding shall have the
right, from time to time, to consent to and approve the execution by the Issuer
and the Trustee of such other indenture or indentures supplemental hereto as
shall be deemed necessary and desirable by the Trustee for the purpose of
modifying, altering, amending, adding to or rescinding, in any particular, any
of the terms or provisions contained in this Indenture or in any Supplemental
Indenture; provided, however, that nothing in this Section shall permit, or be
construed as permitting (a) without the consent of the Registered Owners of all
then Outstanding Obligations, (i) an extension of the maturity date of the
principal of or the interest on any Obligation, or (ii) a reduction in the
principal amount of any Obligation or the rate of interest thereon, or (iii) a

                                       85
<PAGE>

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.

        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. 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.

                                       86

        SECTION 8.05. 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.

        SECTION 8.06. CONSENT OF CURRENCY SWAP PROVIDERS. The parties to this
Indenture acknowledge and agree that, if the Reset Rate Notes are denominated in
a currency other than U.S. Dollars during any related Reset Period, and the
Issuer enters in a Currency Swap Agreement, pursuant to such Currency Swap
Agreement, the Issuer has agreed or will agree (a) to notify the related
Currency Swap Counterparty of any amendment, modification or supplement to this
Indenture or any other Basic Document that would materially adversely affect (i)
the related Currency Swap Counterparty's ability to enforce or protect its
rights or remedies under the related Currency Swap Agreement, (ii) the ability
of the Issuer to timely and fully perform its obligations under the related
Currency Swap Agreement, or (iii) any of the terms of this Indenture which
relates to payments to or rights of the related Currency Swap Counterparty under
either such agreement, and (b) to obtain the written consent of the related
Currency Swap Counterparty to any such amendment, modification or supplement.
Any such amendment, modification or supplement without the written consent of
the related Swap Counterparty shall be void and unenforceable.

        Accordingly, the parties to this Indenture acknowledge and agree that
each Currency Swap Counterparty will be a third-party beneficiary of this
Indenture to the extent of its rights under the related Currency Swap Agreement
in respect of this Indenture and shall be entitled to enforce such rights under
this Indenture. Notices to a Currency Swap Counterparty under this Section shall
be addressed to the applicable Currency Swap Counterparty at the address listed
in the related swap confirmation for that Currency Swap Agreement.

                                   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

        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.

                                       88
<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 lien on and security interest in, and (b) an assignment of, the
Trust Estate.

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

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

        SECTION 9.06. NONLIABILITY OF PERSONS; NO GENERAL OBLIGATION. It is
hereby expressly made a condition of this Indenture that any agreements,
covenants or representations herein contained or contained in the Notes do not
and shall never constitute or give rise to a personal or pecuniary liability or
charge against the organizers, officers, employees, agents or trustees or the
Administrator of the Issuer, or against the general credit of the Issuer, and in
the event of a breach of any such agreement, covenant or representation, no
personal or pecuniary liability or charge payable directly or indirectly from
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 in this Indenture contained be forbidden by any pertinent law or under
any pertinent law be effective to render this Indenture invalid or unenforceable
or to impair the lien hereof, then each such covenant, agreement, waiver, or
part thereof shall itself be and is hereby declared to be wholly ineffective,
and this Indenture shall be construed as if the same were not included herein.

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

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

        SECTION 9.13. PARTIES INTERESTED HEREIN. Nothing in this Indenture
expressed or implied is intended or shall be construed to confer upon, or to
give to, any person or entity, other than the Trustee, the Delaware Trustee, the
Paying Agent, if any, and the Registered Owners of the Obligations, any right,
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 Wells Fargo
Delaware Trust Company, but are made and intended for the purpose of only
binding the Trust Estate, as defined in the Trust Agreement, and the Issuer; (c)
nothing contained herein shall be construed as creating any liability on Wells
Fargo Delaware Trust Company, individually or personally, to perform any
expressed or implied covenant, duty or obligation of any kind whatsoever
contained herein; and (d) under no circumstances shall Wells Fargo Delaware
Trust Company, be personally liable for the payment of any fees, costs,
indebtedness or expenses of any kind whatsoever or be personally liable for the
breach or failure of any obligation, representation, agreement, warranty or
covenant whatsoever made or undertaken by the Delaware Trustee or Issuer
hereunder.

        SECTION 9.20. SUBORDINATION OF CURRENCY SWAP COUNTERPARTIES. All rights
and interest of any Currency Swap Counterparty in the security interest granted
to the Trustee under this Indenture with respect to any Termination Payments
(other than Priority Termination Payments) shall be fully subordinated to the
interests of the Registered Owners of the Notes. No Currency Swap Counterparty
shall have any rights, implied or otherwise, in the Trust Estate with respect to
any Termination Payments (other than Priority Termination Payments) until after
the Outstanding Amount of the Notes has been reduced to zero and the Registered
Owners have been paid all amounts owed to them under this Indenture.
Notwithstanding the foregoing, the provisions of this Section shall not modify
or otherwise affect the contractual priority of payments set forth in Section
5.04(c) hereof. More specifically, no Currency Swap Counterparty shall have any
voting rights or rights to exercise any remedies under this Indenture until
after the Outstanding Amount of the Notes has been reduced to zero and the
Registered Owners have been paid all amounts owed to them under this Indenture.
After the Outstanding Amount of the Notes has been reduced to zero and the
Registered Owners have been paid all amounts owed to them under this Indenture,
each Currency Swap Counterparty shall have all of the rights and obligations,
including all voting rights, of the Registered Owners set forth in this
Indenture.

                                   ARTICLE X

                        PAYMENT AND CANCELLATION OF NOTES
                          AND SATISFACTION OF INDENTURE

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

        SECTION 10.02. SATISFACTION OF INDENTURE.

                (a) If the Issuer shall pay, or cause to be paid, or there shall
        otherwise be paid (i) to the Registered Owners of the Notes, the
        principal of and interest on the Notes, at the times and in the manner
        stipulated in this Indenture; and (ii) to each Counterparty, all Issuer
        Derivative Payments then due, then the pledge of the Trust Estate, and
        all covenants, agreements and other obligations of the Issuer to the
        Registered Owners of Notes shall thereupon cease, terminate and become
        void and be discharged and satisfied. In such event, the Trustee shall
        execute and deliver to the Issuer all such instruments as may be
        desirable to evidence such discharge and satisfaction, and the Trustee
        shall pay over or deliver all money held by it under this Indenture to
        the party entitled to receive the same under this Indenture. If the
        Issuer shall pay or cause to be paid, or there shall otherwise be paid,
        to the Registered Owners of any Outstanding Notes the principal of and
        interest on such Notes and to each Counterparty all Issuer Derivative
        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.

                                       92
<PAGE>

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

                                       93
<PAGE>

                (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 May 2022 Quarterly Distribution Date and (b)
date that is the tenth (10th) Business Day preceding the Quarterly Distribution
Date next succeeding the date 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 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 Amounts 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.

                                       94
<PAGE>

        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 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 5.04(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 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.

        IN WITNESS WHEREOF, the Issuer has caused this Indenture to be executed
in its organizational name and behalf by its Delaware Trustee, and the Trustee,
to evidence its acceptance of the trusts hereby created, has caused this
Indenture to be executed in its organizational name and behalf, all in multiple
counterparts, each of which shall be deemed an original, and the Issuer and the
Trustee have caused this Indenture to be dated as of the date herein above first

                                   NELNET STUDENT LOAN TRUST 2006-1,
                                   a Delaware statutory trust

                calendar year;

where "Determination Period" shall mean the period from and including one
Calculation Date to but excluding the next Calculation Date, "Distribution Date"
shall mean the date of any distribution on the Reset Rate Notes and "Calculation
Date" shall mean, in each year, each of those days in the calendar year that are
specified herein as being the scheduled Distribution Dates.

        "ACTUAL/ACTUAL (PAYMENT BASIS)" shall mean that interest is calculated
on the basis of the actual number of days elapsed in a year of 365 days if the
interest period ends in a non-leap year, or 366 days if the interest period ends
in a leap year, as the case may be.

Period during which the Failed Remarketing Rate was not in effect; or (b) if the
Reset Rate Notes had one or more related Derivative Products in effect during
the previous Reset Period, the weighted average of the floating rates of
interest that were due to the related Counterparties from the Issuer during the

        x + [1/30* (y-x)] plus 0.11%, as determined by the Administrator.

        where:

        x = Three-Month EURIBOR, and

        y = Four-Month EURIBOR, in each case, as of the second Business Day

The Class A-6 Rate shall be changed on each related Reset Date to the interest
rate (which shall not exceed the Failed Remarketing Rate) and Day Count Basis
that will be set forth in the notice required to be delivered by the

        "CMT RATE" shall mean, for any relevant Interest Rate Determination Date
prior to each related Interest Rate Change Date, the rate displayed on the
applicable Designated CMT Moneyline Telerate Page shown below by 3:00 p.m., New
York City time, on that Interest Rate Determination Date under the caption ". .
.. Treasury Constant Maturities . . . Federal Reserve Board Release H.15. . .
..Mondays Approximately 3:45 p.m.," under the column for: (a) if the Designated
CMT Moneyline Telerate Page is 7051, the rate on that Interest Rate
Determination Date; or (b) if the Designated CMT Moneyline Telerate Page is
7052, the average for the week, the month or the quarter, as specified on the
Remarketing Terms Determination Date, ended immediately before the week in which
the related Interest Rate Determination Date occurs. The following procedures
will apply if the CMT Rate cannot be determined as described above: (i) if the
rate described above is not displayed on the relevant page by 3:00 p.m., New
York City time on that Interest Rate Determination Date, unless the calculation
is made earlier and the rate is available from that source at that time on that
Interest Rate Determination Date, then the CMT Rate will be the Treasury
constant maturity rate having the designated index maturity, as published in
H.15(519) or another recognized electronic source for displaying the rate; (ii)
if the applicable rate described above is not published in H.15(519) or another
recognized electronic source for displaying such rate by 3:00 p.m., New York
City time on that Interest Rate Determination Date, unless the calculation is
made earlier and the rate is available from one of those sources at that time,
then the CMT Rate will be the Treasury constant maturity rate, or other United
States Treasury rate, for the index maturity and with reference to the relevant
Interest Rate Determination Date, that is published by either the Board of
Governors of the Federal Reserve System or the United States Department of the
Treasury and that the Administrator determines to be comparable to the rate
formerly displayed on the Designated CMT Moneyline Telerate Page shown above and
published in H.15(519); (iii) if the rate described in the prior paragraph

                                      A-3
<PAGE>

cannot be determined, then the Administrator will determine the CMT Rate to be a
yield to maturity based on the average of the secondary market closing offered
rates as of approximately 3:30 p.m., New York City time, on the relevant
Interest Rate Determination Date reported, according to their written records,
by leading primary United States government securities dealers in New York City.
The Administrator will select five such securities dealers and will eliminate
the highest and lowest quotations or, in the event of equality, one of the
highest and lowest quotations, for the most recently issued direct noncallable
fixed rate obligations of the United States Treasury ("Treasury Notes") with an
original maturity of approximately the designated index maturity and a remaining
term to maturity of not less than the designated index maturity minus one year
in a representative amount; (iv) if the Administrator cannot obtain three
Treasury Note quotations of the kind described in clause (iii) above, the
Administrator will determine the CMT Rate to be the yield to maturity based on
the average of the secondary market bid rates for Treasury Notes with an
original maturity longer than the designated CMT index maturity which have a
remaining term to maturity closest to the designated CMT index maturity and in a
representative amount, as of approximately 3:30 p.m., New York City time, on the
relevant Interest Rate Determination Date of leading primary United States
government securities dealers in New York City. In selecting these offered
rates, the Administrator will request quotations from at least five such
securities dealers and will disregard the highest quotation (or if there is
equality, one of the highest) and the lowest quotation (or if there is equality,
one of the lowest). If two Treasury Notes with an original maturity longer than
the designated CMT index maturity have remaining terms to maturity that are
equally close to the designated CMT index maturity, the Administrator will
obtain quotations for the Treasury Note with the shorter remaining term to
maturity; (v) if three or four but not five leading primary United States
government securities dealers are quoting as described in the prior paragraph,
then the CMT Rate for the relevant Interest Rate Determination Date will be
based on the average of the bid rates obtained and neither the highest nor the
lowest of those quotations will be eliminated; or (vi) if fewer than three
leading primary United States government securities dealers selected by the
Administrator are quoting as described in clause (v) above, the CMT Rate will
remain the CMT Rate then in effect on that Interest Rate Determination Date.

        "COMMERCIAL PAPER RATE" shall mean, for any relevant Interest Rate
Determination Date prior to each related Interest Rate Change Date, the Bond
Equivalent Yield (as defined below) of the rate for 90-day commercial paper, as
published in H.15(519) prior to 3:00 p.m., New York City time, on that Interest
Rate Determination Date under the heading "Commercial Paper--Financial." If the
rate described above is not published in H.15(519) by 3:00 p.m., New York City
time, on that Interest Rate Determination Date, unless the calculation is made
earlier and the rate was available from that source at that time, then the
Commercial Paper Rate will be the Bond Equivalent Yield of the rate on the

                                      A-4
<PAGE>

relevant Interest Rate Determination Date, for commercial paper having the index
maturity specified on the Remarketing Terms Determination Date, as published in
H.15 Daily Update or any other recognized electronic source used for displaying
that rate under the heading "Commercial Paper--Financial." For purposes of this
definition of "Commercial Paper Rate," the "Bond Equivalent Yield" equals
[(NxD)/[360(Dx90)] times 100], where "D" refers to the per annum rate determined
as set forth above, quoted on a bank discount basis and expressed as a decimal
and "N" refers to 365 or 366, as the case may be. If the rate described above
cannot be determined, the Commercial Paper Rate will remain the commercial paper

specified on the Remarketing Terms Determination Date, the Commercial Paper Rate
will be subject to a Lock-In Period of six Business Days.

Rate Notes into the applicable currency; (c) converts the interest rate on the
Reset Rate Notes from a LIBOR-based rate to a fixed or floating rate payable in
the applicable currency; (d) converts the U.S. Dollar equivalent of all
secondary market trade proceeds received on the related Reset Date resulting in
the successful remarketing of the Reset Rate Notes or the exercise of a Call
Option into the applicable currency for the payment of principal to the
tendering Noteholders of the Reset Rate Notes; and (e) pays to the Paying Agent,
on behalf of the Issuer, for the benefit of the tendering Noteholders of the

Determination Date prior to each related Interest Rate Change Date, the rate set

               (b) Interest on the Reset Rate Notes after the initial Reset
        Period may be reset to bear either a fixed or floating rate of interest
        at the option of the Remarketing Agents, in consultation with the

               (c) In the event that the Reset Rate Notes are reset (i) to bear
        (or continue to bear) interest at a floating rate, (ii) to bear (or
        continue to bear) a fixed rate of interest and/or (iii) to be
        denominated (or continue to be denominated) in a currency other than
        U.S. Dollars, and the Remarketing Agents, in consultation with the
        Administrator determine that it would be in the best interest of the
        Issuer based on existing market conditions to enter into one or more

        Commercial Paper Rate, or at a fixed rate or (B) to be denominated in a
        currency other than U.S. Dollars unless one or more Derivative Products
        are entered into as of the related Reset Date that results in the Rating
        Agency Condition being satisfied. In connection with each Derivative
        Product, the Remarketing Agents shall solicit bids from Eligible
        Counterparties in accordance with the procedures set forth in Section
        2.09(c) of this Appendix A.

        related Reset Period, to receive allocations of principal at the
        priority level set forth in Section 5.04(c) of the Indenture on each
        Quarterly Distribution Date; provided, however, that such amounts
        referred to in this clause (ii) shall not be paid in reduction of the
        Outstanding Amount of the Class A-6 Notes, and instead all such amounts
        shall be deposited into the Class A-6 Accumulation Account for payment
        to the Noteholders of the Class A-6 Notes or the related Currency Swap
        Counterparty, as applicable, on or about the next related Reset Date as
        set forth in Section 2.10(a) of this Appendix A.

        each Clearing Agency's standard procedures) to the each Clearing Agency
        or the Noteholders of the Reset Rate Notes if Definitive Notes have been
        issued, as applicable, the Trustee and the Rating Agencies on the
        related Remarketing Terms Determination Date.

               (e) In addition, prior to the Remarketing Terms Determination
        Date, the Administrator shall cause the Schedule Replacement Order with
        respect to the Reset Rate Notes to be delivered to the Trustee and the
        Clearing Agencies. Furthermore, the Administrator shall also prepare, on
        behalf of the Issuer, a preliminary Remarketing Prospectus, dated as of
        the Remarketing Terms Determination Date, setting forth the relevant
        terms for the next Reset Period in addition to current information
        regarding the pool of Financed Eligible Loans.

        SECTION 2.04. ALL HOLD RATE.

        (a) On each Remarketing Terms Determination Date for the Reset Rate
Notes which is denominated in U.S. Dollars during both the then-current Reset
Period and the immediately following Reset Period, the Remarketing Agents, in
consultation with the Administrator, will establish the related All Hold Rate
for the Reset Rate Notes. With respect to the Reset Rate Notes that are either
in a Foreign Exchange Mode during the then-current Reset Period or will be reset
into a Foreign Exchange Mode on the immediately following Reset Date, all
Noteholders of the Reset Rate Notes will be deemed to have tendered their Reset
Rate Notes on the Reset Date, regardless of any desire by such Noteholder of the
Reset Rate Notes to retain their ownership thereof, and no All Hold Rate will be
applicable.

        (b) The All Hold Rate will only be applicable if 100% of the Noteholders
of the Reset Rate Notes deliver timely Hold Notices wherein they elect to hold
their Reset Rate Notes for the next related Reset Period. If applicable, the
related interest rate for the Reset Rate Notes during the immediately following
Reset Period will not be less than the All Hold Rate. If the rate of interest
using the Spread or fixed rate of interest established on the Spread
Determination Date is higher than the All Hold Rate, then upon a successful
remarketing of the Reset Rate Notes, all Noteholders of the Reset Rate Notes who
delivered a Hold Notice agreeing to be subject to the All Hold Rate instead will
be entitled to the higher rate of interest during the immediately following
Reset Period.

        SECTION 2.05. FAILED REMARKETING.

               (a) With respect to each Reset Date for which the holder of the
        Call Option does not deliver the related Call Option Notice and the
        Reset Rate Notes are not redeemed pursuant to Section 2.13 of the
        Indenture, a Failed Remarketing will be declared by the Remarketing
        Agents and the provisions of this Section will apply if any of the
        conditions set forth in the definition of "Failed Remarketing" are
        applicable. In order to prevent the declaration of a Failed Remarketing,
        the Remarketing Agents will have the option, but not the obligation, to
        purchase any Reset Rate Notes tendered that they are not otherwise able
        to remarket or with respect to which a committed purchaser defaults on
        their purchase obligations.

               (b) At any time a Failed Remarketing is declared on the Reset
        Rate Notes when denominated in U.S. Dollars, (i) all the Reset Rate
        Notes will be deemed to have been retained by the applicable Noteholders
        on the related Reset Date, regardless of any deemed mandatory or
        voluntary tenders made to Remarketing Agents; (ii) the Failed
        Remarketing Rate for the Reset Rate Notes will apply for the related
        Reset Period; and (iii) a Reset Period of three months will be
        established for the Reset Rate Notes.

               (c) At any time a Failed Remarketing is declared on the Reset
        Rate Notes when in a Foreign Exchange Mode, (i) all the Reset Rate Notes
        will be deemed to have been retained by the applicable Noteholders on
        the related Reset Date, regardless of any deemed mandatory tenders made
        to Remarketing Agents, (ii) the Reset Rate Notes will remain denominated
        in such foreign currency, (iii) each related Currency Swap Counterparty
        will be entitled to receive quarterly payments from the Issuer at the
        Extension Rate, (iv) the Issuer will be entitled to receive from each
        Currency Swap Counterparty, for payment to the applicable Noteholders,
        quarterly index rate payments at the Failed Remarketing Rate and (v) a
        Reset Period of three months will be established for the Reset Rate
        Notes. In addition, if the Reset Rate Notes are in a Foreign Exchange
        Mode at the time a Failed Remarketing is declared, the provisions of
        Sections 2.09(a)(i) and (ii) shall also apply.

               (d) If there is a Failed Remarketing of the Reset Rate Notes,
        Noteholders of the Reset Rate Notes shall not be entitled to exercise
        any remedies as a result of the failure of the Reset Rate Notes to be
        remarketed on the related Reset Date.

        SECTION 2.06. CALL OPTION.

               (a) With respect to each Reset Date, Nelnet, Inc. is hereby
        granted a Call Option for the purchase of not less than 100% of the
        Reset Rate Notes, exercisable at a price equal to 100% of the

        to the Noteholders of the Reset Rate Notes as a payment of principal on
        the related Quarterly Distribution Date, plus any accrued and unpaid
        interest not paid by the Issuer on the applicable Reset Date.

               (b) Nelnet, Inc. may transfer ownership of the Call Option at any
        time to any Nelnet Eligible Purchaser.

               (c) A Call Option may be exercised with respect to the Reset Rate
        Notes at any time on or prior to the determination of the related Spread
        or fixed rate or the declaration of a Failed Remarketing, as applicable,
        on the related Spread Determination Date by delivery of a Call Option
        Notice; provided that such Call Option Notice may not be delivered
        before the day following the last Quarterly Distribution Date
        immediately preceding the next applicable Reset Date. Once written
        notice of the exercise of a Call Option is given, such exercise may not
        be rescinded.

               (e) All amounts due and owing to the Noteholders of the Reset
        Rate Notes shall be remitted on or before the related Reset Date by the
        holder of the related Call Option in accordance with the standard
        procedures established by the Clearing Agencies for transfer of
        securities to ensure timely payment of principal to the Noteholders of
        the Reset Rate Notes on the related Reset Date.

               (f) In the event that a Call Option is exercised with respect the
        Reset Rate Notes then in a Foreign Exchange Mode, the holder of such
        Call Option shall deliver the U.S. Dollar Equivalent Principal Amount
        remaining after all payments of principal are made with respect to the
        related Quarterly Distribution Date, and interest (if applicable) owing
        to the Noteholders of the Reset Rate Notes to the Remarketing Agents for
        delivery to the Counterparties to the related Currency Swap Agreements,
        who shall exchange such amount into the applicable currency for delivery
        to the London Paying Agent for delivery to the Noteholders of the Reset
        Rate Notes; provided, however, that if there are no such Currency Swap
        Agreements then in effect, the holder of such Call Option shall remit
        all amounts due and owing to the Remarketing Agents for delivery to the
        London Paying Agent for delivery to the Noteholders of the Reset Rate
        Notes in the applicable currency on or before the Reset Date in
        accordance with the standard procedures established by the related
        Clearing Agencies for transfer of securities to ensure timely payment of
        principal to the Noteholders of the Reset Rate Notes on the related
        Reset Date.

               (g) If a Call Option is exercised with respect to the Reset Rate
        Notes, (i) the interest rate on the Reset Rate Notes will be the Call
        Rate, (ii) the Reset Rate Notes will be denominated in U.S. Dollars and
        (iii) a Reset Period of three months will be established. At the end of
        such three month Reset Period, the holder of the related Call Option may
        either remarket the Reset Rate Notes pursuant to the remarketing
        procedures set forth in this Appendix A and in the Remarketing
        Agreement, or retain the Reset Rate Notes for one or more successive
        three-month Reset Periods at the then-current Call Rate. In the event
        the holder of the related Call Option chooses to remarket the Reset Rate
        Notes, such holder shall be solely responsible for all costs and
        expenses relating to the preparation of any new offering document and
        any other related costs and expenses associated with such remarketing,
        other than the fees of the Remarketing Agents, as more fully set forth
        in Section 3 of the Remarketing Agreement.

               (h) Other than in connection with the exercise of a Call Option,
        none of Nelnet, Inc., the Issuer or any of their affiliates shall have
        the ability to purchase any Reset Rate Notes tendered to the Remarketing
        Agents.

        SECTION 2.07. HOLD NOTICE. If the Reset Rate Notes are denominated in
U.S. Dollars during both the then-current Reset Period and the immediately
following Reset Period, the Noteholders of the Reset Rate Notes will have the
option to deliver a Hold Notice to any Remarketing Agent setting forth their
desire to hold their Reset Rate Notes for the next Reset Period at a rate of
interest not less than the All Hold Rate and on the terms set forth in the
related Remarketing Terms Notice, at any time on or after the Remarketing Terms

                                       A-18
<PAGE>

Determination Date until the Notice Date. Such Hold Notice may be delivered as
an oral statement to a Remarketing Agent, if subsequently confirmed in writing
within 24 hours, which confirmation may be in the form of an e-mail if timely
received by the Remarketing Agent. If a Noteholder of the Reset Rate Notes does
not timely deliver a Hold Notice to a Remarketing Agent (such Hold Notice not to
be considered delivered until actually received by such Remarketing Agent), that
Noteholder of the Reset Rate Notes will be deemed to have tendered for
remarketing 100% of the Outstanding Amount of its Reset Rate Notes. Any duly
delivered Hold Notice will be irrevocable, but will be subject to a mandatory
tender of the Reset Rate Notes pursuant to any exercise of the related Call
Option. All of the Reset Rate Notes, whether tendered or not, will bear interest
during any related Reset Period on the same terms.

        SECTION 2.08. SPREAD DETERMINATION DATE.

               (a) On each Spread Determination Date, unless a Failed
        Remarketing has been declared or the holder of the related Call Option
        has delivered the related Call Option Notice or the Reset Rate Notes are
        to be redeemed pursuant to Section 2.13 of the Indenture, the
        Administrator, the Issuer and the Remarketing Agents will enter into a
        Supplemental Remarketing Agency Agreement.

               (b) If pursuant to the Remarketing Terms Notice, the Remarketing
        Agents, in consultation with the Administrator, have determined that the
        Reset Rate Notes are to be reset to bear a fixed rate of interest, then
        the applicable fixed rate of interest for the corresponding Reset Period
        will be determined on the Spread Determination Date by adding (i) the
        applicable spread as determined by the Remarketing Agents on the Spread
        Determination Date; and (ii) the yield to maturity on the Spread
        Determination Date of the applicable fixed rate pricing benchmark,
        selected by the Remarketing Agents, as having an expected weighted
        average life based on a scheduled maturity at the next Reset Date, which
        would be used in accordance with customary financial practice in pricing
        new issues of asset-backed securities of comparable average life;
        provided that such fixed rate of interest will in no event be lower than
        the related All Hold Rate, if applicable. The Remarketing Agents shall
        determine the applicable fixed rate of interest for the Reset Rate Notes
        (by reference to the applicable fixed rate pricing benchmark plus or
        minus the spread determined on the Remarketing Terms Determination Date)
        on each Spread Determination Date irrespective of whether no remarketing
        will occur as the result of the application of the All Hold Rate. In
        addition, on the related Spread Determination Date, the Remarketing
        Agents, in consultation with the Administrator, shall determine the
        Supplemental Interest Deposit Amount, if any, for the Reset Rate Notes.

               (c) If pursuant to the Remarketing Terms Notice, the Remarketing
        Agents, in consultation with the Administrator, have determined that the
        Reset Rate Notes are to be reset to bear a floating rate of interest,
        then, on the related Spread Determination Date, the Remarketing Agents
        will establish the applicable Spread to be added or subtracted from the
        applicable Index; provided that such floating rate of interest will in
        no event be lower than the related All Hold Rate, if applicable. In
        addition, on the related Spread Determination Date, the Remarketing
        Agents, in consultation with the Administrator, shall determine the
        Supplemental Interest Deposit Amount, if any, for the Reset Rate Notes.

                                      A-19

               (d) If required pursuant to Section 2.01(c) of this Appendix A,
        on the related Reset Date the Issuer shall enter into either (i) one or
        more Currency Swap Agreements, if the Reset Rate Notes are to be reset
        into a Foreign Exchange Mode, or (ii) one or more Derivative Products if
        the Reset Rate Notes are to be reset in U.S. Dollars and to bear
        interest at a fixed rate or at a floating rate other than one based on
        LIBOR or a Commercial Paper Rate, with an Eligible Counterparty.

               (e) On or immediately following the Spread Determination Date,
        the Remarketing Agents will communicate in writing (including facsimile
        or other electronic transmission if in accordance with each Clearing
        Agency's standard procedures) the contents of the Spread Determination
        Notice to each Clearing Agency or the Noteholders of the Reset Rate
        Notes if Definitive Notes have been issued, as applicable, with
        instructions to distribute such notices to its related participants, or
        to the Noteholders of the Reset Rate Notes, as applicable, the Trustee
        and the Rating Agencies. The Spread Determination Date Notice will
        contain: (i) the determined Spread or fixed rate of interest, as the
        case may be, or, if applicable, a statement that the All Hold Rate or
        the Failed Remarketing Rate will be in effect for the immediately
        following Reset Period, (ii) any applicable currency exchange rate,
        (iii) the identity of any selected Counterparty or Counterparties, if
        applicable, (iv) if applicable, the floating rate (or rates) of interest
        to be due to each selected Counterparty with respect to each Quarterly
        Distribution Date during the immediately following Reset Period and (v)
        any other information that the Administrator or the Remarketing Agents
        deem applicable. Furthermore, if the Reset Rate Notes are to be reset
        into a Foreign Exchange Mode, the currency exchange rate, the Extension
        Rate due to each related Currency Swap Counterparty and the Failed
        Remarketing Rate applicable to the Reset Rate Notes for the immediately
        following Reset Period will be determined pursuant to the terms of the
        related Currency Swap Agreement and contained in the Spread
        Determination Notice. In addition, if required for the immediately
        following Reset Period, on or before the related Spread Determination
        Date the Administrator will arrange for new or additional securities
        identification codes to be obtained as required. Furthermore, the
        Administrator, on behalf of the Issuer, will prepare the final
        Remarketing Prospectus, dated the Spread Determination Date, setting
        forth the terms of the Reset Rate Notes for the upcoming Reset Period.

        SECTION 2.09. CURRENCY SWAP AGREEMENTS AND INTEREST RATE EXCHANGE
AGREEMENTS.

               (a) If the Class A-6 Notes are to be reset into a Foreign
        Exchange Mode, on the related Reset Date, the Administrator will enter
        into (not in its individual capacity, but solely as Administrator on
        behalf of the Issuer) or will instruct the Trustee to enter into (not in
        its individual capacity, but solely as Trustee) one or more Currency
        Swap Agreements for the related Reset Period.

                      (i) Each Currency Swap Counterparty which is party to a
               related Currency Swap Agreement will be entitled to receive: (A)
               on the effective date of such Currency Swap Agreement, all
               secondary market trade proceeds received from purchasers of the

               each applicable Quarterly Distribution Date, (x) an interest rate
               of Three-Month LIBOR, plus or minus a spread, as determined from
               the bidding process described in subsection (c) of this Section
               (other than as may be interpolated for an initial or final
               calculation period under that Currency Swap Agreement),
               multiplied by the U.S. Dollar Equivalent Principal Amount of the
               Class A-6 Notes, and multiplied by a fraction determined by the
               number of days in the applicable Interest Accrual Period and the
               applicable Day Count Basis and (y) all payments of principal in
               U.S. Dollars that are allocated to the Class A-6 Notes; provided
               that if the Class A-6 Notes are then structured not to receive a
               payment of principal until the end of the related Reset Period,
               all principal payments allocated to the Class A-6 Notes on any
               Quarterly Distribution Date will be deposited into the Class A-6
               Accumulation Account and paid to the related Currency Swap
               Counterparties on or about the next Reset Date as set forth in
               the related Currency Swap Agreements (including all sums required
               to be deposited therein on the Reset Date), but excluding all
               investment earnings thereon, and (C) on a Reset Date

               secondary market trade proceeds or proceeds from the exercise of

               the Reset Rate Notes (if in U.S. Dollars), from the new Currency

               non-U.S. Dollar currency) or from the holder of the related Call
               Option or the sale of the Financed Eligible Loans pursuant to
               Section 10.03 or 10.04 of the Indenture or Section 2.13(a) of
               this Appendix A, as applicable. With respect to the Initial
               Currency Swap Agreements, each applicable Initial Currency Swap

               by the Issuer from purchasers of the Reset Rate Notes (which
               shall be net of any applicable underwriting commission).

                      (ii) In addition, each related Currency Swap Counterparty
               will be obligated to pay to the Paying Agent, on behalf of the
               Issuer (for payment to the Noteholders of the Reset Rate Notes,
               if applicable): (A) on the effective date of such Currency Swap
               Agreement, the U.S. Dollar equivalent of all secondary market

               determined by the number of days in the applicable Interest
               Accrual Period and the applicable Day Count Basis, and (y) the

               Initial Currency Swap Counterparty shall be obligated to pay to
               the Issuer on the Date of Issuance, in lieu of the payments

               Remarketing has occurred, up to any including the Reset Date
               resulting in a successful remarketing or an exercise of the
               related Call Option or redemption for the Reset Rate Notes,
               payments of interest and principal to Noteholders of the Reset
               Rate Notes will be made no later than the second Business Day
               following the related Reset Date without the payment of any
               additional interest.

               (b) On each Reset Date if the Reset Rate Notes are to be reset in
        U.S. Dollars, and a Derivative Product is required pursuant to Sections
        2.01(c) of this Appendix A and subsection (d) of this Section, then the
        Administrator will enter into (not in its individual capacity, but
        solely as Administrator on behalf of the Issuer) or will instruct the
        Trustee to enter into (not in its individual capacity, but solely as
        Trustee), one or more Interest Rate Swap Agreements for the next Reset
        Period to facilitate the Issuer's ability to pay applicable interest at
        the related interest rate.

                      (i) Each Counterparty which is party to a related Interest
               Rate Swap Agreements will be entitled to receive on each
               Quarterly Distribution Date an interest rate of Three-Month
               LIBOR, plus or minus a spread, as determined from the bidding
               process described in subsection (c) of this Section, multiplied
               by the Outstanding Amount of the Reset Rate Notes and multiplied
               by a fraction determined by the number of days in the applicable
               Interest Accrual Period and the applicable Day Count Basis.

                      (ii) In addition, each related Counterparty which is a
               party to a related Interest Rate Swap Agreements will be
               obligated to pay to the Issuer on each Quarterly Distribution
               Date, the applicable rate of interest on the Reset Rate Notes
               multiplied by the Outstanding Amount of the Reset Rate Notes and
               multiplied by a fraction determined by the number of days in the
               applicable Interest Accrual Period and the applicable Day Count
               Basis.

               (c) Other than with respect to the Initial Currency Swap
        Agreement, the Remarketing Agents, in consultation with the
        Administrator, in determining the Counterparty to each required
        Derivative Product, will solicit bids from at least three Eligible
        Counterparties and will select the lowest of these bids to provide the
        interest rate swap and/or currency exchange swap(s). If the lowest
        bidder specifies a notional amount that is less than the Outstanding
        Amount of the Reset Rate Notes, the Remarketing Agents, in consultation
        with the Administrator, may select more than one Eligible Counterparty,
        but only to the extent that such additional Eligible Counterparties have
        provided the next lowest received bid or bids, and enter into more than
        one Swap Agreement that result in the Rating Agency Condition being
        satisfied.

               (d) Other than with respect to the Initial Currency Swap
        Agreement, it is a condition precedent to the entering into of any
        Derivative Product and the setting of the amount to be paid to the
        related Counterparty that the Rating Agency Condition is satisfied. No
        Derivative Product will be entered into or caused to be entered into by
        the Issuer, the Administrator on its behalf or the Remarketing Agents,
        for any Reset Period where the related Call Option has been exercised,
        the Notes are to be redeemed pursuant to Section 2.13 of the Indenture
        or a Failed Remarketing has been declared.

               (e) Each Currency Swap Agreement will terminate at the earliest
        to occur of (i) the next succeeding Reset Date for which there is a
        successful remarketing, (ii) the Reset Date for which the related Call
        Option is exercised, (iii) the Quarterly Distribution Date on which the
        Outstanding Amount of the Reset Rate Notes is reduced to zero (including
        as the result of a redemption of the Reset Rate Notes pursuant to
        Section 2.13 of the Indenture) or (iv) the Note Final Maturity Date of
        the Reset Rate Notes. No Currency Swap Agreement will terminate solely
        due to the declaration of a Failed Remarketing. Each Interest Rate Swap
        Agreement will terminate on the earliest to occur of the next Reset
        Date, or the occurrence of an event specified in clause (iii) or (iv)
        above.

               (f) With respect to each Currency Swap Agreement, and in the
        event that a Failed Remarketing is declared, the rate of interest due to
        each related Currency Swap Counterparty from the Issuer on each
        Quarterly Distribution Date will be increased to the Extension Rate and
        the rate due to the Issuer from each related Currency Swap Counterparty
        will change to equal the Failed Remarketing Rate.

               (g) The Issuer shall not enter into any amendment to any Currency
        Swap Agreement to cure any ambiguity in, or to correct or supplement any
        provision of any Currency Swap Agreement, unless the Issuer has
        determined, and the Trustee has agreed in writing at the written
        direction of the Issuer, that the amendment will not materially
        adversely affect the interests of the Noteholders and provided that the
        Issuer has provided reasonable notice to the Rating Agencies of such
        amendment and the Rating Agency Condition is satisfied.

        SECTION 2.10. PAYMENT OF PRINCIPAL ON THE RESET RATE NOTES.

               (a) If, on any Quarterly Distribution Date, a principal payment
        would be payable to the Class A-6 Notes when such Class is structured to
        receive a payment of principal only at the end of the related Reset
        Period, those principal payments will be allocated to the Class A-6
        Notes and deposited into the Class A-6 Accumulation Account of the
        Accumulation Fund where it will remain until the next Reset Date for the
        Class A-6 Notes as provided in Section 5.08 of the Indenture (except
        that if the Class A-6 Notes are in a Foreign Exchange Mode, principal
        will be paid according to the provisions of Sections 2.09(a)(i) and
        (a)(ii) of this Appendix A), unless an Event of Default under the
        Indenture has occurred (in which case the Trustee will distribute all
        sums on deposit therein to the Noteholders of the Class A-6 Notes in
        accordance with the provisions of Section 6.02 of the Indenture).

               (b) On each Reset Date for the Class A-6 Notes when such Class is
        structured to receive a payment of principal only at the end of the
        related Reset Period, all sums, if any, then on deposit in the Class A-6
        Accumulation Account of the Accumulation Fund, including any allocation
        of principal made on the same date will be distributed by the Trustee,
        at the direction of the Administrator, as set forth in Section 5.08 of
        the Indenture, to the Noteholders of the Class A-6 Notes, as of the
        related Record Date, or the related Currency Swap Counterparty or
        Counterparties (as applicable), in reduction of principal of the Class
        A-6 Notes; provided, that, in the event on any Quarterly Distribution
        Date the amount on deposit in the related Accumulation Account of the
        Accumulation Fund would equal the Outstanding Amount of the Reset Rate
        Notes, no additional amounts will be deposited into the Class A-6
        Accumulation Account of the Accumulation Fund and all amounts therein
        will be distributed by the Trustee, at the direction of the
        Administrator, as set forth in Section 5.08 of the Indenture, on the
        next related Reset Date to the related Noteholders (or to the related
        Currency Swap Counterparty or Counterparties), and on such Reset Date
        the Reset Rate Notes will no longer be Outstanding.

               (c) The Trustee, subject to sufficient available funds therefor,
        at the direction of the Administrator and pursuant to Section 5.04(c) of
        the Indenture, will deposit into a Supplemental Interest Fund, the
        related Supplemental Interest Deposit Amount. On each Quarterly
        Distribution Date, all sums (which shall include investment earnings) on
        deposit in the Supplemental Interest Fund shall be transferred to the
        Collection Fund.

        SECTION 2.11. REMARKETING AGENTS; REMARKETING FEE FUND.

               (a) The initial Remarketing Agents, appointed pursuant to the
        terms of the Remarketing Agreement are Banc of America Securities LLC,
        Credit Suisse (USA) LLC and Deutsche Bank Securities Inc. The terms and
        conditions of the Remarketing Agreement will govern the duties and
        obligations of the Remarketing Agents. The Administrator, the Issuer and

                                      A-24
<PAGE>

        the Remarketing Agents will enter into on each related (i) Remarketing
        Terms Determination Date, a related Remarketing Agency Agreement in form
        and substance substantially the same as Appendix B to the Remarketing
        Agreement, unless (A) a Failed Remarketing is declared, (B) the holder
        of the related Call Option has delivered the related Call Option Notice
        on or prior to such date or (C) the Reset Rate Notes are to be redeemed
        pursuant to Section 2.13 of the Indenture; and (ii) Spread Determination
        Date, a Supplemental Remarketing Agency Agreement in form and substance
        substantially the same as Appendix C to the Remarketing Agreement,
        unless (A) a Failed Remarketing is declared, (B) the holder of the
        related Call Option has delivered the related Call Option Notice on or
        prior to such date, (C) the Reset Rate Notes are to be redeemed pursuant
        to Section 2.13 of the Indenture or (D) if applicable, 100% of the
        related Noteholders have timely delivered a Hold Notice and the All Hold
        Rate will apply for the next related Reset Period.

               (b) Excluding all Reset Rate Notes for which a Remarketing Agent
        has received a timely delivered Hold Notice, if applicable (or if the
        holder of the related Call Option has delivered the related Call Option
        Notice), on the Reset Date that commences each Reset Period, each Reset
        Rate Note will be automatically tendered, or deemed tendered, to the
        relevant Remarketing Agent for remarketing by such Remarketing Agent on
        the Reset Date at 100% of its Outstanding Amount. If the Reset Rate
        Notes are held in book-entry form, 100% of the Outstanding Amount of the
        Reset Rate Notes will be paid by the Remarketing Agents in accordance
        with the standard procedures of the applicable Clearing Agencies.

               (c) The Remarketing Agents will attempt, on a reasonable efforts
        basis and in accordance with the terms and conditions of the Remarketing
        Agreement and the related Remarketing Agency Agreement, to remarket the
        tendered Reset Rate Notes of the applicable Class at a price equal to
        100% of the Outstanding Amount of the Reset Rate Notes so tendered.

               (d) Purchasers of the Reset Rate Notes will be credited with
        their positions on the applicable Reset Date with respect to positions
        held through DTC or on the next Business Day with respect to positions
        held through the European Clearing Systems. No payment delay to existing
        Noteholders of the Reset Rate Notes holding U.S. Dollar-denominated
        Reset Rate Notes through DTC will occur on the related Reset Date if
        Reset Rate Notes are denominated in U.S. Dollars during the immediately
        following Reset Period.

               (e) Each of the Remarketing Agents, in its individual or any
        other capacity, may buy, sell, hold and deal in any Class of the Notes,
        including, but not limited to, purchasing any tendered Reset Rate Notes
        as part of the remarketing process. Any Remarketing Agent that owns a
        Reset Rate Note may exercise any vote or join in any action which any
        beneficial owner of any Class of Notes may be entitled to exercise or
        take with like effect as if it did not act in any capacity under the
        Remarketing Agency Agreement. Any Remarketing Agent, in its individual
        capacity, either as principal or agent, may also engage in or have an
        interest in any financial or other transaction with the Issuer, the
        Depositor, the Master Servicer, each Subservicer, the Trustee (in its
        individual capacity), the Eligible Lender Trustee (in its individual
        capacity) or the Administrator as freely as if it did not act in any

                                      A-25
<PAGE>

        capacity under the Remarketing Agreement or any Remarketing Agency
        Agreement. No Noteholder or beneficial owner of any Reset Rate Note will
        have any rights or claims against any Remarketing Agent as a result of
        such Remarketing Agent's not purchasing any tendered Reset Rate Note,
        which results in the declaration of a Failed Remarketing.

               (e) Each of the Remarketing Agents will be entitled to receive a
        fee in connection with their services rendered for each successful
        remarketing of the Reset Rate Notes in the amount set forth in the
        Remarketing Agreement and the related Remarketing Agency Agreement.
        Subject to the terms and conditions set forth in the Remarketing
        Agreement, the Administrator, in its sole discretion, may change the
        Remarketing Agents for the Reset Rate Notes for any Reset Period at any
        time on or before the related Remarketing Terms Determination Date. In
        addition, the Administrator will appoint one or more additional
        Remarketing Agents, if necessary, for a Reset Date when the Reset Rate
        Notes will be remarketed in a non-U.S. Dollar currency. Furthermore, a
        Remarketing Agent may resign at any time; provided that no resignation
        may become effective on a date that is later than 15 Business Days prior
        to a Remarketing Terms Determination Date.

               (f) In accordance with Section 5.01(e) of the Indenture, on the
        Date of Issuance, the Issuer shall establish the Remarketing Fee Fund,
        which will be held by the Trustee for the benefit of the Remarketing
        Agents and the Noteholders. The fees associated with each successful
        remarketing will be payable directly to the Remarketing Agents from
        amounts on deposit from time to time in the Remarketing Fee Account. On
        each Quarterly Distribution Date, Available Funds will be deposited into
        the Remarketing Fee Account, in the priority set forth in Section
        5.04(c) of the Indenture, in an amount up to the Quarterly Funding
        Amount; provided that if the amount on deposit in the Remarketing Fee
        Fund, after the payment of any remarketing fees therefrom, exceeds the
        Reset Period Target Amount, such excess will be withdrawn on the related
        Quarterly Distribution Date, deposited into the Collection Fund and
        included in the Available Funds for that Quarterly Distribution Date.
        All investment earnings on deposit in the Remarketing Fee Fund will be
        withdrawn on the next Quarterly Distribution Date, deposited into the
        Collection Account and included in Available Funds for that Quarterly
        Distribution Date. In the event that the fees owed to any Remarketing
        Agent on a Reset Date exceed the amount then on deposit (after giving
        effect to distributions made on such Reset Date) in the Remarketing Fee
        Account, such shortfall shall be paid from the Collection Fund on future
        Quarterly Distribution Dates in the priority set forth in Section
        5.04(c) of the Indenture. The Issuer shall also be responsible for
        certain remarketing costs and expenses to the extent set forth in
        Section 3 of the Remarketing Agreement, which shall be paid on each
        Quarterly Distribution Date from the Collection Fund at the priority set
        forth in Section 5.04(c) of the Indenture.

        SECTION 2.12. EXECUTION OF DOCUMENTS. The Trustee is hereby authorized
and directed to execute and deliver, not in its individual capacity, but solely
as Trustee, any Derivative Products including any Interest Rate Swap Agreements
and any Currency Swap Agreements, including the Initial Currency Swap Agreement,
and any required supplement, amendment or replacement thereof, as the

                                      A-26
<PAGE>

Administrator, in writing and from time to time, shall instruct the Trustee. The
Trustee shall not be liable to any party, any third party or any Noteholder for
any such actions taken at the written instruction of the Administrator.
Notwithstanding the foregoing, in the event that the Trustee declines or fails
to execute or deliver any such document, instrument, certificate or agreement as
instructed by the Administrator, the Administrator is hereby authorized, in its
sole discretion, to execute and deliver, not in its individual capacity but
solely as Administrator on behalf of the Issuer, all such required documents,
instruments, certificates and agreements. The foregoing authorization shall
represent a limited power of attorney granted by the Issuer to the Administrator
to act on its behalf and the Administrator shall not be liable to any party, any
third party or any Noteholder for any such actions taken in good faith and in
accordance with these Reset Rate Note Procedures.

        SECTION 2.13. PURCHASE OPTION.

               (a) If (i) there are no longer any Class A Notes, other than the
        Reset Rate Notes, Outstanding, (ii) the Reset Rate Notes bear interest
        at the Failed Remarketing Rate and (iii) the Pool Balance is less than
        25% of the Initial Pool Balance, Nelnet, Inc. is hereby granted an
        option to purchase the Financed Eligible Loans held in the Trust Estate
        at a purchase price equal to the greater of the Minimum Purchase Amount
        and the fair market value of such Financed Eligible Loans as of the
        Quarterly Distribution Date immediately preceding the date of sale for
        the purpose of redeeming the Reset Rate Notes and the Class B Notes on
        any Quarterly Distribution Date pursuant to Section 2.13(b) of the
        Indenture. The holder of the Purchase Option shall exercise such option
        by delivering a written notice stating its desire to exercise this
        option to the Clearing Agencies, the Trustee, the Remarketing Agents and
        the Rating Agencies five Business Days prior to such Quarterly
        Distribution Date and by delivering to the Trustee an amount equal to
        the purchase price of such Financed Eligible Loans on or before the
        third Business Day prior to such Quarterly Distribution Date. The
        Trustee may consult, and, at the direction of the Issuer, 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 by any Nelnet Eligible Purchaser. From
        the proceeds of the sale of the Financed Eligible Loans and the amounts
        on deposit in the Funds and Accounts, the Trustee shall deposit amounts
        sufficient to redeem the Reset Rate Notes and the Class B Notes on the
        next succeeding Quarterly Distribution Date pursuant to the redemption
        provisions of Section 2.13(b) of the Indenture and to pay any Issuer
        Derivative Payments into separate Accounts established by the Trustee
        within the Collection Fund and shall deposit the remainder to the
        Collection Fund. The Trustee shall use the amounts on deposit in those
        Accounts, to redeem the Reset Rate Notes and the Class B Notes on the
        applicable Quarterly Distribution Date and to pay any such Issuer
        Derivative Payments pursuant to the corresponding Derivative Product.

               (b) Nelnet, Inc. may transfer ownership of either or both of the
        Purchase Options described in this Section at any time to any Nelnet
        Eligible Purchaser.

                      ELIGIBLE LOAN ACQUISITION CERTIFICATE

        This Eligible Loan Acquisition Certificate is submitted pursuant to the

are hereby authorized and requested to disburse to _________________ (the
"Seller") the sum of $__________ (or, in the case of an exchange, the Eligible
Loans listed in Exhibit A hereto) for the acquisition of Eligible Loans. With
respect to the Eligible Loans so to be acquired, the Issuer hereby certifies as
follows:

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

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

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

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

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

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

or in the performance of any of its covenants and agreements made in the Student
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.

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

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

covenants and agreements made in any Contract of Insurance or the Guarantee
Agreement applicable to the Acquired Eligible Loans.

Acquisition Fund is in compliance with the provisions of the Indenture.

        11. The undersigned is authorized to sign and submit this Certificate on

<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-1 (the "Class
A-1 Notes"), which, together with the Issuer's Student Loan Asset-Backed Notes,
Senior Class A-2, Class A-3, Class A-4, Class A-5 and Class A-6 (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 and any
Derivative Products 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 Class A-1 Noteholder's Principal
Distribution Amount for such Quarterly Distribution Date. "Quarterly
Distribution Date" means the twenty-third (23rd) 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 23, 2006.

        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 May 2022
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).

                                      B-1-4
<PAGE>

        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, minus 0.02%. The "Class A-1 Rate" for the first Interest
Accrual Period shall be determined by reference to the following formula:

        x + [1/30* (y-x)] minus 0.02%, as determined by the Administrator.

        where:

        x = Three-Month LIBOR, and

        y = Four-Month LIBOR, in each case, as of the second Business Day before
the start of the first Interest Accrual Period.

        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.

        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-2 (the "Class
A-2 Notes"), which, together with the Issuer's Student Loan Asset-Backed Notes,
Senior Class A-1, Class A-3, Class A-4, Class A-5 and Class A-6 (together with
the Class A-2 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 and any
Derivative Products 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-2 Notes shall be payable on each Quarterly
Distribution Date in an amount equal to the Class A-2 Noteholder's Principal
Distribution Amount for such Quarterly Distribution Date. "Quarterly
Distribution Date" means the twenty-third (23rd) 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 23, 2006.

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

        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 May 2022
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).

        Interest on the Class A-2 Notes shall be payable on each Quarterly
Distribution Date on the principal amount outstanding of the Class A-2 Notes
until the principal amount thereof is paid in full, at a rate per annum equal to
the Class A-2 Rate. The "Class A-2 Rate" for each Interest Accrual Period, other
than the first Interest Accrual Period, shall be equal to the applicable
Three-Month LIBOR, plus 0.01%. The "Class A-2 Rate" for the first Interest
Accrual Period shall be determined by reference to the following formula:

        x + [1/30* (y-x)] plus 0.01%, as determined by the Administrator.

        where:

        x = Three-Month LIBOR, and

        y = Four-Month LIBOR, in each case, as of the second Business Day before
the start of the first Interest Accrual Period.

        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.

        Nelnet Student Loan Trust 2006-1, 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 Class A-4 Noteholder's Principal Distribution Amount for such Quarterly
Distribution Date, as described in the Indenture of Trust, dated as of February
1, 2006, between the Issuer (by Wells Fargo Delaware Trust Company, in its
capacity as Delaware Trustee) and Zions First National Bank, a national banking
association, as eligible lender trustee and Trustee (the "Trustee") (capitalized
terms used but not defined herein being defined in Article I of the Indenture,
which also contains rules as to usage that shall be applicable herein);
provided, however, that the entire unpaid principal amount of this Note shall be
due and payable on the Maturity Date specified above (the "Class A-4 Maturity
Date").

        The Issuer shall pay interest on this Note at the rate per annum equal
to the Class A-4 Rate (as defined herein), on each Quarterly Distribution Date

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, Senior Class A-4 (the "Class
A-4 Notes"), which, together with the Issuer's Student Loan Asset-Backed Notes,
Senior Class A-1, Class A-2, Class A-3, Class A-5 and Class A-6 (together with
the Class A-4 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 and any
Derivative Products 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-4 Notes shall be payable on each Quarterly
Distribution Date in an amount equal to the Class A-4 Noteholder's Principal
Distribution Amount for such Quarterly Distribution Date. "Quarterly
Distribution Date" means the twenty-third (23rd) 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 23, 2006.

        As described on the face hereof, the entire unpaid principal amount of
this Note shall be due and payable on the Class A-4 Maturity Date.
Notwithstanding the foregoing, the entire unpaid principal amount of the Notes
shall be due and payable on the date on which (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 May 2022
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).

                                     B-4-4
<PAGE>

        Interest on the Class A-4 Notes shall be payable on each Quarterly
Distribution Date on the principal amount outstanding of the Class A-4 Notes
until the principal amount thereof is paid in full, at a rate per annum equal to
the Class A-4 Rate. The "Class A-4 Rate" for each Interest Accrual Period, other
than the first Interest Accrual Period, shall be equal to the applicable
Three-Month LIBOR, plus 0.09%. The "Class A-4 Rate" for the first Interest
Accrual Period shall be determined by reference to the following formula:

        x + [1/30* (y-x)] plus 0.09%, as determined by the Administrator.

        where:

        x = Three-Month LIBOR, and

        y = Four-Month LIBOR, in each case, as of the second Business Day before
the start of the first Interest Accrual Period.

        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.

        Nelnet Student Loan Trust 2006-1, 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 Class A-5 Noteholder's Principal Distribution Amount for such Quarterly
Distribution Date, as described in the Indenture of Trust, dated as of February
1, 2006, between the Issuer (by Wells Fargo Delaware Trust Company, in its
capacity as Delaware Trustee) and Zions First National Bank, a national banking
association, as eligible lender trustee and Trustee (the "Trustee") (capitalized
terms used but not defined herein being defined in Article I of the Indenture,
which also contains rules as to usage that shall be applicable herein);
provided, however, that the entire unpaid principal amount of this Note shall be
due and payable on the Maturity Date specified above (the "Class A-5 Maturity
Date").

<PAGE>

        The Issuer shall pay interest on this Note at the rate per annum equal
to the Class A-5 Rate (as defined herein), on each Quarterly Distribution Date

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,

<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-5 (the "Class
A-5 Notes"), which, together with the Issuer's Student Loan Asset-Backed Notes,
Senior Class A-1, Class A-2, Class A-3, Class A-4 and Class A-6 (together with
the Class A-5 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 and any
Derivative Products 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-5 Notes shall be payable on each Quarterly
Distribution Date in an amount equal to the Class A-5 Noteholder's Principal
Distribution Amount for such Quarterly Distribution Date. "Quarterly
Distribution Date" means the twenty-third (23rd) 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 23, 2006.

        As described on the face hereof, the entire unpaid principal amount of
this Note shall be due and payable on the Class A-5 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 May 2022
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).

                                      B-5-4
<PAGE>

        Interest on the Class A-5 Notes shall be payable on each Quarterly
Distribution Date on the principal amount outstanding of the Class A-5 Notes
until the principal amount thereof is paid in full, at a rate per annum equal to
the Class A-5 Rate. The "Class A-5 Rate" for each Interest Accrual Period, other
than the first Interest Accrual Period, shall be equal to the applicable
Three-Month LIBOR, plus 0.11%. The "Class A-5 Rate" for the first Interest
Accrual Period shall be determined by reference to the following formula:

        x + [1/30* (y-x)] plus 0.11%, as determined by the Administrator.

        where:

        x = Three-Month LIBOR, and

        y = Four-Month LIBOR, in each case, as of the second Business Day before
the start of the first Interest Accrual Period.

        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.

to merge or consolidate, subject to the rights of the Trustee and the Registered
Owners under the Indenture.

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.

        NELNET STUDENT LOAN TRUST 2006-1, a statutory trust organized under the
laws of the State of Delaware (the "Issuer," which term includes any successor
under the Indenture of Trust, dated as of February 1, 2006 (the "Indenture"),
between the Issuer, Zions First National Bank, a national banking association,
as trustee (the "Trustee," which term includes any successor trustee under the
Indenture) and as eligible lender trustee) for value received, hereby promises
to pay to the Registered Owner (stated above) or registered assigns, the
Principal Sum hereof, but solely from the revenues and receipts hereinafter
specified and not otherwise, on the Maturity Date specified above (subject to
the right of prior redemption hereinafter described), at the designated
corporate trust office of the Trustee (or the principal office of the London
Paying Agent if the Class A-6 Notes are denominated in a currency other than
U.S. Dollars), as paying agent, trustee, authenticating agent and registrar for
the Notes, or a duly appointed successor paying agent, and to pay interest in
arrears on said Principal Sum, but solely from the revenues and receipts
hereinafter specified and not otherwise, to the Registered Owner hereof from the
most recent Quarterly Distribution Date to which interest has been paid hereon,
until the payment of said principal sum in full.

<PAGE>

        Any capitalized words and terms used as defined words and terms in this
note and not otherwise defined herein shall have the meanings given them in the
Indenture.

        The Issuer shall pay interest on this note at the rate set forth in
Schedule A attached hereto, on each Quarterly Distribution Date until the
principal of this note is paid or made available for payment as set forth in
Schedule A attached hereto, on the principal amount of this note outstanding on
the preceding Quarterly Distribution Date (after giving effect to all payments
of principal made on the preceding Quarterly Distribution Date, if any).
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") as set forth in Schedule A attached hereto.

        The principal of and interest on this note are payable in the currency
set forth in Schedule A attached hereto. If the specified date for any payment
of principal or interest accrued to such specified date shall be a day other
than a Business Day then such payment may be made on the next succeeding
Business Day, with the same force and effect as if made on the specified date
for such payment without additional interest. Interest on the Class A-6 Notes
during the initial Reset Period and during any subsequent Reset Period when the
Class A-6 Notes bear a fixed rate of interest and are denominated in a currency
other than U.S. Dollars will be calculated in accordance with the Actual/Actual
(ISMA) Accrual Method, or another Day Count Basis as may be established on the
related Remarketing Terms Determination Date. Interest on the Class A-6 Notes
during any Reset Period when such notes bear a fixed rate of interest and are
denominated in U.S. Dollars will be computed on the basis of a 360 day year of
twelve 30 day months.

        Principal of the Class A-6 Notes shall be allocable on each Quarterly
Distribution Date and payable as set forth in Schedule A attached hereto to the
extent moneys have been allocated therefor pursuant to the Indenture.
"Distribution Date" means the twenty-third (23rd) day of each February, May,
August and November, or, if any such date is not a Business Day, the next
succeeding Business Day, commencing May 23, 2006.

        If during any Reset Period (including the initial Reset Period) the
Class A-6 Notes constitute Non-Amortizing Reset Rate Notes (as defined in the
Indenture), the registered owners of the Class A-6 Notes will not be paid
principal on any related Quarterly Distribution Date when principal is allocated
to the Class A-6 Notes. All such allocated principal will be deposited into the
related Accumulation Account for payment on the Class A-6 Notes, generally, on
the next related Reset Date in accordance with the procedures set forth in
Appendix A to the Indenture. All principal payments on the Class A-6 Notes shall
be made pro rata to the registered owners thereof.

<PAGE>

        Interest on the Class A-6 Notes shall be payable on each Quarterly
Distribution Date on the principal amount outstanding of the Class A-6 Notes
until the principal amount thereof is paid in full, at a rate per annum equal to
the Class A-6 Rate. The Class A-6 Rate will be reset on the Initial Reset Date
set forth in Schedule A attached hereto and on each Reset Date thereafter in
accordance with the provisions of Appendix A to the Indenture. The Initial Reset
Date for the Class A-6 Notes is the Quarterly Distribution Date in February of
2016. The "Class A-6 Rate" for each Interest Accrual Period during the initial
Reset Period, other than the first Interest Accrual Period, shall be equal to an
annual rate of Three-Month EURIBOR plus 0.11%, calculated on the basis of the
actual number of days elapsed and a 360 day year. The "Class A-6 Rate" for the
first Interest Accrual Period shall be determined by reference to the following
formula:

        x + [1/30* (y-x)] plus 0.11%, as determined by the Administrator.

        where:

        x = Three-Month EURIBOR, and

        y = Four-Month EURIBOR, in each case, as of the second Business Day
before the start of the first Interest Accrual Period.

        Interest on the Class A-6 Notes after the initial Reset Period may be
reset to bear either a fixed or floating rate of interest at the option of the
Remarketing Agents, in consultation with the Administrator. The interest rate,
or the mechanism for calculating the interest rate, on the Class A-6 Notes will
be reset as of each Reset Date as determined by (i) the Remarketing Agents, in
consultation with the Administrator, with respect to (A) the length of the Reset
Period, (B) whether the rate is fixed or floating and (I) if floating, the
applicable Index, or (II) if fixed, the applicable pricing benchmark (C) the
applicable Day Count Basis, (D) the applicable currency denomination, i.e., U.S.
Dollars, Euros, Pounds Sterling or another non-U.S. Dollar currency, (E) if in
Foreign Exchange Mode, the applicable distribution dates on which interest will
be paid to the Noteholders of the Reset Rate Notes, if other than quarterly, (F)
the applicable Interest Rate Determination Dates within each Interest Accrual

        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-6 (the "Class
A-6 Notes"), which, together with the Issuer's Student Loan Asset-Backed Notes,
Senior Class A-1, Class A-2, Class A-3, Class A-4 and Class A-5 (together with
the Class A-6 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 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 May 2022
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).

        The Class A-6 Notes and the Class B Notes are also subject to redemption
if (a) there are no Class A Notes, other than the Class A-6 Notes, Outstanding
and (b) the Class A-6 Notes are bearing interest at the Failed Remarketing Rate,
upon a sale of the Financed Eligible Loans as provided in Section 2.13(a) of
Appendix A to the Indenture, in whole only, on any Quarterly Distribution Date
on or after the date on which the Pool Balance is less than 25% of the Initial
Pool Balance, at a redemption price equal to the principal amount thereof being
redeemed, plus accrued interest, if any, due and to such Quarterly Distribution
Date.

        All Class A-6 Notes called for redemption will cease to bear interest
after the specified redemption or purchase date, provided funds for their
payment are on deposit at the place of payment at the time. Preferably five, but
not less than two Business Days prior to each Quarterly Distribution Date on
which the Class A-6 Notes are to be redeemed, the Trustee shall cause notice
such redemption to be given by mailing a copy of the notice by first-class mail
to the Administrator and Registered Owners of the Class A-6 Notes, at their
address as the same shall last appear upon the registration books on such date;
provided, however, that failure to give such notice, or any defect therein,
shall not affect the validity of any proceedings for the reduction or redemption
of the Class A-6 Notes.

        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-6 Notes are and will be secured by the Trust Estate pledged
as security therefor as provided in the Indenture. The Class A Notes and any
Derivative Products 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.

respect hereof or of the Indenture, against the Trustee (or the London Paying

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.

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

<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, Class A-3, Class A-4, Class A-5 and Class
A-6 (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 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 and any
Derivative Products 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 Class B Noteholder's Principal
Distribution Amount for such Quarterly Distribution Date. "Quarterly
Distribution Date" means the twenty-third (23rd) 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 23, 2006.

        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 May 2022
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).

                                      B-7-4
<PAGE>

        The Class A-6 Notes and the Class B Notes are also subject to redemption
if (a) there are no Class A Notes, other than the Class A-6 Notes, Outstanding
and (b) the Class A-6 Notes is bearing interest at the Failed Remarketing Rate,
upon a sale of the Financed Eligible Loans as provided in Section 2.13(a) of
Appendix A to the Indenture, in whole only, on any Quarterly Distribution Date
on or after the date on which the Pool Balance is less than 25% of the Initial
Pool Balance, at a redemption price equal to the principal amount thereof being
redeemed, plus accrued interest, if any, due and to such Quarterly Distribution
Date.

        All Class B Notes called for redemption will cease to bear interest
after the specified redemption or purchase date, provided funds for their
payment are on deposit at the place of payment at the time. Preferably five, but
not less than two Business Days prior to each Quarterly Distribution Date on
which the Class B Notes are to be redeemed, the Trustee shall cause notice such
redemption to be given by mailing a copy of the notice by first-class mail to
the Administrator and registered owners of the Class B Notes, at their address
as the same shall last appear upon the registration books on such date;
provided, however, that failure to give such notice, or any defect therein,
shall not affect the validity of any proceedings for the reduction or redemption
of the Class B Notes.

        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 0.22%. The "Class B Rate" for the first Interest Accrual Period
shall be determined by reference to the following formula:

        x + [1/30* (y-x)] plus 0.22%, as determined by the Administrator.

        where:

        x = Three-Month LIBOR, and

the start of the first Interest Accrual Period.

        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.

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

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

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.
