                              INDEMNITY AGREEMENT

     AGREEMENT dated as of July 16, 2003, among J.P. Morgan Securities Inc. and
Morgan Stanley & Co. Incorporated (the "Representatives") on behalf of the
other underwriters listed on Schedule A to the Underwriting Agreement referred
to below (each an "Underwriter" and collectively, with the Representatives, the
"Underwriters") and Nelnet Loan Services, Inc., a Nebraska corporation (the
"Company").

     WHEREAS, the Representatives have entered into an underwriting agreement
dated July 16, 2003 (the "Underwriting Agreement") with Nelnet Student Loan
Funding, LLC, a Delaware limited liability company ("Nelnet Funding"), pursuant
to which Nelnet Funding has agreed to cause Nelnet Student Loan Trust 2003-2, a
Delaware statutory trust (the "Issuer"), to sell, and the Underwriters have
agreed to purchase, subject to the conditions set forth in the Underwriting
Agreement, the Issuer's Student Loan Asset-Backed Notes (the "Notes"), which
Notes are being offered for sale by the Underwriters pursuant to a Prospectus
dated July 2, 2003 and a Prospectus Supplement dated July 21, 2003
(collectively, the "Prospectus"), included as part of the Issuer's Registration
Statement on Form S-3 (Registration No. 333-82280) (the "Registration
Statement"); and

     WHEREAS, the Notes will be secured by, among other things, a pool of
Financed Eligible Loans that will be master serviced by Nelnet, Inc. pursuant to
a Master Servicing Agreement dated as of July 1, 2003 (the "Servicing
Agreement") among the Issuer, Nelnet, Inc., as master servicer and
administrator, and Nelnet Funding;

     WHEREAS, the parties hereto wish to set forth their understanding
concerning certain matters relating to indemnification and contribution;

     NOW, THEREFORE, in consideration of the foregoing premises and for other
good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows.

     1.   DEFINED TERMS.  Capitalized terms used herein but not otherwise
defined shall have the respective meanings set forth in the Underwriting
Agreement.

     2.   Indemnification and Contribution.

          (a)  The Company agrees to indemnify and hold harmless each
     Underwriter, and each person, if any, who controls an Underwriter within
     the meaning of either Section 15 of the Securities Act of 1933 (the "1933
     Act") or Section 20 of the Securities Exchange Act of 1934 (the "1934 Act")
     from and against any and all losses, claims, damages, liabilities and
     expenses arising out of or based upon any untrue statement or alleged
     untrue statement of a material fact contained in the Registration
     Statement, the Prospectus, or in any amendment or supplement thereto, or
     any preliminary prospectus, or arising out of or based upon any omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not

misleading, except to the extent Nelnet Funding is not obligated to indemnify
the Underwriters pursuant to Section 5 (a) of the Underwriting Agreement. The
foregoing indemnity agreement shall be in addition to any liability which the
Company may otherwise have.

     (b)  If any action, suit or proceeding shall be brought against an
Underwriter or any person controlling an Underwriter in respect of which
indemnity may be sought against the Company, the applicable Underwriter or such
controlling person shall promptly notify the parties against whom
indemnification is being sought (the "indemnifying parties"), but the omission
so to notify the indemnifying party will not relieve it from any liability which
it may have to any indemnified party under Sections 2(a) and 2(c) hereof except
to the extent that the indemnifying party is materially prejudiced by such
omission, and in no event shall the omission so to notify relieve the
indemnifying party from any liability which it may otherwise have. In case any
such action is brought against any indemnified party and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (who shall not,
except with the consent of the indemnified party, be counsel to the indemnifying
party). The applicable Underwriter or any such controlling person shall have the
right to employ separate counsel in any such action, suit or proceeding and to
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of such Underwriter or such controlling person unless
(i) the indemnifying parties have agreed in writing to pay such fees and
expenses, (ii) the indemnifying parties have failed to assume the defense and
employ counsel, or (iii) the named parties to any such action, suit or
proceeding (including any impleaded parties) include both such Underwriter or
such controlling person and the indemnifying parties and such Underwriter or
such controlling person shall have been advised by its counsel that there may be
one or more legal defenses available to it which are different from or
additional to or in conflict with those available to the indemnifying parties
and in the reasonable judgment of such counsel it is advisable for such
Underwriter or such controlling person to employ separate counsel (in which case
the indemnifying party shall not have the right to assume the defense of such
action, suit or proceeding on behalf of such Underwriter or such controlling
person). It is understood, however, that the indemnifying parties shall, in
connection with any one such action, suit or proceeding or separate but
substantially similar or related actions, suits or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of only one separate firm of
attorneys (in addition to any local counsel) at any time for an Underwriter and
controlling persons not having actual or potential differing interests with such
Underwriter or among themselves, which firm shall be designated in writing by
such Underwriter, and that all such fees and expenses shall be reimbursed on a
monthly basis as provided in paragraph (a) hereof. An indemnifying party will
not, without the prior written consent of the indemnified party, settle or
compromise or consent to the entry of any judgment with respect to any pending
or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each

                                      -2-

<PAGE>
indemnified party from all liability arising out of such claim, action, suit or
proceeding and does not include a statement as to, or an admission of, fault,
culpability or a failure to act by or on behalf of an indemnified party.

     (c)  If the indemnification provided for in this Agreement is unavailable
to an indemnified party under paragraph (a) hereof in respect of any losses,
claims, damages, liabilities or expenses referred to therein, then an
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or expenses (i) in such proportion
as is appropriate to reflect the relative benefits received by the Company on
the one hand and the applicable Underwriter on the other hand from the sale of
the Notes, or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company on the one hand and the applicable Underwriter on the other
in connection with the statements or omissions that resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative benefits received by the Company on the
one hand and the applicable Underwriter on the other shall be deemed to be in
the same proportion as the total gross proceeds from the sale of the Notes bear
to the total underwriting discounts and commissions received by the applicable
Underwriter in connection with the sale of the Notes. The relative fault of the
Company on the one hand and the applicable Underwriter on the other hand shall
be determined by reference to, among other things, the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

     (d)  The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Agreement were determined by a pro
rata allocation or by any other method of allocation that does not take account
of the equitable considerations referred to in paragraph (c) above. The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages, liabilities and expenses referred to in paragraph (c) above shall be
deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in connection with
defending any such action, suit or proceeding. Notwithstanding the provisions of
this Agreement, no Underwriter shall be required to contribute any amount in
excess of the amount by which the total underwriting discounts and commissions
received by such Underwriter with respect to the Notes underwritten by such
Underwriter exceed the sum of the amount of any damages which such Underwriter
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission and the amount of any damages such
Underwriter has been required to pay under the Underwriting Agreement. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the 1933 Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

     (e)  Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Agreement shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements

                                      -3-
<PAGE>
     contained in this Agreement shall remain operative and in full force and
     effect, regardless of (i) any investigation made by or on behalf of the
     Underwriters, or any person controlling it or its directors or officers,
     (ii) acceptance of any Notes and payment therefor hereunder, and (iii) any
     termination of this Agreement and the Underwriting Agreement. A successor
     to an Underwriter, the Company or any person controlling any of them or
     their respective directors or officers, shall be entitled to the benefits
     of the indemnity, contribution and reimbursement agreements contained in
     this Agreement.

     3. NOTICES. All demands, notices and communications hereunder shall be in
writing and shall be deemed to have been duly given if mailed, by registered
or certified mail, return receipt requested, or, if by other means, when
received by the other parties at the address set forth for such parties in the
Underwriting Agreement (in the case of the Underwriters) or the Servicing
Agreement (in the case of the Company), or such other address as may hereafter
be furnished to the other parties by like notice. Any such demand, notice or
communication hereunder shall be deemed to have been received on the date
delivered to or received at the premises of the addressee (as evidenced, in the
case of registered or certified mail, by the date noted on the return receipt).

     4. COUNTERPARTS. For the purpose of facilitating proving this Agreement,
and for other purposes, this Agreement may be executed simultaneously in any
number of counterparts. Each counterpart shall be deemed to be an original, and
all such counterparts shall constitute one and the same instrument.

     5. GOVERNING LAW. The Agreement shall be construed in accordance with the
laws of the State of New York and the obligations, rights and remedies of the
parties hereunder shall be determined in accordance with the laws of the State
of New York, except to the extent preempted by Federal Law.

receipt of written direction from the Administrator or the Note Insurer, shall
take such actions, including but not limited to filing Uniform Commercial Code
Financing Statements and continuation statements, as the Administrator or the
Note Insurer may direct as necessary to ensure that the security interests
created hereby would be deemed to be a perfected security interest of first
priority under applicable law and will be maintained as such throughout the term
of the Agreement. Neither the Administrator nor the Note Insurer shall direct
the Trustee to take any action inconsistent with this Agreement.

Trust as provided in this Section 2.5 be, and be construed as, an absolute
contribution of the Underlying NELNET Residual Rights and the Maintenance and
Operating Expenses by the NELNET Depositor to the Trust and thereafter for the
benefit of the Subordinated Certificateholders. Nevertheless, if,
notwithstanding the intent of the parties, the Underlying NELNET Residual Rights
and the Maintenance and Operating Expenses are held to be the property of the
NELNET Depositor, or, if for any other reason this Agreement is held or deemed
to create a security interest in the Underlying NELNET Residual Rights and the
Maintenance and Operating Expenses, then it is intended that (a) this Agreement
shall also be deemed to be a security agreement within the meaning of Articles 8
and 9 of the Uniform Commercial Code of any applicable jurisdiction; (b) the
conveyance provided for in this Section 2.5 shall be deemed to be a grant by the
NELNET Depositor to the Trust of a security interest in all the NELNET
Depositor's right, title and interest in and to the Underlying NELNET Residual
Rights and the Maintenance and Operating Expenses and all amounts payable to the
holders of the Underlying NELNET Residual Rights and the Maintenance and
Operating Expenses after the Closing Date in accordance with the terms thereof,
all proceeds of the conversion, voluntary or involuntary, of the foregoing into
cash, instruments, security or other property, including without limitation all
amounts from time to time held or invested in the Collection Account, the
Distribution Account or the Reserve Account, whether in the form of cash,
instruments, securities or other property; and (c) the possession by the Trust
or its agent of the Underlying NELNET Residual Rights and the Maintenance and
Operating Expenses and such other items of property as constitute instruments,
money, negotiable documents or chattel paper shall be deemed to be "possession
by the secured party" for purposes of perfecting the security interest pursuant
to the Uniform Commercial Code of any applicable jurisdiction. The Trustee, upon
receipt of written direction from the Administrator or the Note Insurer, shall
take such actions, including but not limited to filing Uniform Commercial Code
Financing Statements and continuation statements, as the Administrator or the
Note Insurer may direct as necessary to ensure that the security interests
created hereby would be deemed to be a perfected security interest of first
priority under applicable law and will be maintained as such throughout the term
of the Agreement. Neither the Administrator nor the Note Insurer shall direct
the Trustee to take any action inconsistent with this Agreement.

         Section 2.6. Declaration of Trust.

         The Trustee hereby declares that it will hold the Trust Property in
trust upon and subject to the conditions set forth herein first to secure the
payment of the Notes and payments due and owing to the Note Insurer under this
Agreement, the Insurance Agreement and the Financial Guaranty Agreement and
thereafter for the use and benefit of the Subordinated Certificateholders. It is
the intention and agreement of the parties hereto that the Trust constitute a
business trust under the Business Trust Statute of which the Subordinated
Certificateholders are the beneficial owners and that this Agreement constitute
the governing instrument of such business trust. It is the intention and
agreement of the parties hereto that, solely for income and franchise tax
purposes, the Trust shall be treated as a grantor trust. Nevertheless, if,
notwithstanding the intent of the parties the Trust is not held to be a grantor
trust, solely for income and franchise tax purposes the Trust shall be treated
as a partnership, with the Subordinated Certificateholders as the sole partners
thereof. The parties agree that, unless otherwise required by appropriate tax
authorities, the Trust will file or cause to be filed annual or other necessary
returns, reports and other forms consistent with the characterization of the
Trust as a grantor trust or, if necessary, a partnership for such tax purposes.
Effective as of the date hereof, the Trustee shall have all rights, powers,
authority, and authorization set forth herein and in the Business Trust Statute
with respect to accomplishing the purposes of the Trust.

         Section 2.7. Liability of the Noteholders and Subordinated
Certificateholders.

         Except as otherwise set forth in Section 2.12, no Noteholder or
Subordinated Certificateholder shall have any personal liability for any
liability or obligation of the Trust or by reason of any action taken by the
parties to this Agreement pursuant to any provisions of this Agreement or any
Related Document. The Subordinated Certificateholders shall be entitled to the
same limitation of personal liability extended to shareholders of corporations
under the General Corporation Law of the State of Delaware.

         Section 2.8. Title to Trust Property.

         (a) Legal title to all the Trust Property shall be vested at all times
in the Trust as a separate legal entity except where applicable law in any
jurisdiction requires title to any part of the Trust Property to be vested in a
trustee or trustees, in which case title shall be deemed to be vested in the
Trustee, a co-trustee and/or a separate trustee, as the case may be.

         (b) Neither the Noteholders nor the Subordinated Certificateholders
shall have legal title to any part of the Trust Property. The Noteholders shall
be entitled to receive payments, and the Subordinated Certificateholders shall
be entitled to receive distributions, only in accordance with Articles IV, VII
and VIII. No transfer, by operation of law or otherwise, of any right, title or
interest by any Noteholder or Subordinated Certificateholder of its ownership
interest in any Note or Subordinated Certificate shall operate to terminate this
Agreement or the trusts hereunder or entitle any transferee to an accounting or
to the transfer to it of legal title to any part of the Trust Property.

         Section 2.9. Situs of Trust.

         The Trust will be located and administered in the State of Delaware.

from having employees within or without the State of Delaware. All bank accounts

        If any one of the following events (an "Administrator Default") shall

        trustee of an Underlying Trust, as applicable, to make any required
        distributions with respect to the Underlying Residual Rights, the

                                       35

<PAGE>

        Maintenance and Operating Expenses or any other item of Trust Property
        within the time period specified herein or therein, which failure
        continues unremedied for three Business Days after written notice of
        such failure is received by the Administrator from the Trustee or the
        Note Insurer or after discovery of such failure by an officer of the
        Administrator; or

               (2) any failure by the Administrator duly to observe or to
        perform in any material respect any other covenants or agreements of the
        Administrator set forth in this Agreement, which failure shall (i)
        materially and adversely affect the rights of the Note Insurer or
        Noteholders and (ii) continue unremedied for a period of 30 days after
        the date on which written notice of such failure, requiring the same to
        be remedied, shall have been given (A) to the Administrator by the
        Trustee or the Note Insurer or (B) to the Administrator and to the
        Trustee and the Note Insurer by the Noteholders representing not less
        than 66 2/3% of the aggregate outstanding Principal Amount of the Notes
        with the prior written consent of the Note Insurer;

               (3) an Insolvency Event shall have occurred with respect to the
        Administrator;

then, and in each and every case, so long as the Administrator Default shall not
have been remedied, the Trustee or the Noteholders evidencing not less than 25%
of the aggregate outstanding Principal Amount of the Notes, with the consent of
the Note Insurer, or the Note Insurer, by notice then given in writing to the
Administrator (and to the Trustee and the Note Insurer if given by the
Noteholders) may terminate all the rights and obligations (other than the
obligations set forth in Sections 2.3A and 5.8 hereof) of the Administrator
under this Agreement. On or after the receipt by the Administrator of such
written notice, all authority and power of the Administrator under this
Agreement shall, without further action, pass to and be vested in the Trustee or
such successor Administrator consented to by the Note Insurer as may be
appointed under Section 2.6A; and, without limitation, the Trustee is hereby
authorized and empowered to execute and deliver, for the benefit of the
predecessor Administrator, as attorney-in-fact or otherwise, any and all
documents and other instruments, and to do or accomplish all other acts or
things necessary or appropriate to effect the purposes of such notice of
termination. The predecessor Administrator shall cooperate with the successor
Administrator and the Trustee in effecting the termination of the
responsibilities and rights of the predecessor Administrator under this
Agreement. All reasonable costs and expenses (including attorneys' fees)
incurred in connection with amending this Agreement to reflect such succession
as Administrator pursuant to this Section shall be paid by the predecessor
Administrator upon presentation of reasonable documentation of such costs and
expenses. Upon receipt of notice of the occurrence of an Administrator Default,
the Trustee shall give notice thereof to the Rating Agencies and the Note
Insurer.

        Section 2.6A. Appointment of Successor.

        (a) Upon receipt by the Administrator of notice of termination pursuant
to Section 2.5A, or the resignation by the Administrator in accordance with the
terms of this Agreement, the predecessor Administrator shall continue to perform
its functions as Administrator under this Agreement in the case of termination,

                                       36

<PAGE>

only until the date specified in such termination notice or, if no such date is
specified in a notice of termination, until receipt of such notice and, in the
case of resignation, until the later of (x) the date 120 days from the delivery
to the Trustee and the Note Insurer of written notice of such resignation (or
written confirmation of such notice) in accordance with the terms of this
Agreement and (y) the date upon which the predecessor Administrator shall become
unable to act as Administrator, as specified in the notice of resignation and
accompanying opinion of counsel. In the event of the termination hereunder of
the Administrator, the Depositors shall appoint a successor Administrator
acceptable to the Note Insurer and the Trustee, and the successor Administrator
shall accept its appointment by a written assumption in form acceptable to the
Note Insurer and the Trustee. In the event that a successor Administrator has
not been appointed at the time when the predecessor Administrator has ceased to
act as Administrator, in accordance with this Section, the Trustee without
further action shall automatically be appointed the successor Administrator and
the Trustee shall be entitled to the Administration Fee in accordance with the
provisions of this Agreement. Notwithstanding the above, the Trustee shall, if
it shall be unwilling or legally unable so to act, or if requested by the Note
Insurer, appoint or petition a court of competent jurisdiction to appoint, with
the consent of the Note Insurer, any established institution whose regular
business shall include the servicing of student loans, as the successor to the
Administrator, as the case may be, under this Agreement; provided, however, that
such right to appoint or to petition for the appointment of any such successor
servicer shall in no event relieve the Trustee from any obligations otherwise
imposed on it until such successor has in fact assumed such appointment.

        (b) Upon appointment, the successor Administrator (including the Trustee
acting as successor Administrator) shall be the successor in all respects to the
predecessor Administrator and shall be subject to all the responsibilities,
duties and liabilities arising thereafter relating thereto placed on the
predecessor Administrator and shall be entitled to an amount agreed to by such
successor Administrator as the case may be (which shall not exceed the
Administration Fee without the consent of the Note Insurer) and all the rights
granted to the predecessor Administrator by the terms and provisions of this
Agreement.

        (c) The Administrator may not resign unless it is prohibited from
serving as such by law as evidenced by an opinion of counsel to such effect
delivered to the Trustee and the Note Insurer. Notwithstanding the foregoing or
anything to the contrary herein or in the other Related Documents, the Trustee,
to the extent it is acting as successor Administrator pursuant hereto shall be
entitled to resign within 30 days of its appointment as successor Administrator.

        Section 2.7A. Notification to Noteholders and Subordinated
Certificateholders.

        Upon any termination or resignation of, or appointment of a successor
to, the Administrator pursuant to this Article IIA, the Trustee shall give
prompt written notice thereof to Note Registrar (who shall then give prompt
written notice thereof to the Noteholders), Subordinated Certificateholders, the
Note Insurer and the Rating Agencies (which, in the case of any such appointment
of a successor, shall consist of prior written notice thereof to the Rating
Agencies).

aggregate outstanding Principal Amount of the Notes with the consent of the Note
Insurer, or the Note Insurer, may, on behalf of all Noteholders and Subordinated
Certificateholders, waive in writing any default by the Administrator in the
performance of its obligations hereunder and any consequences thereof, except a
default in making any required deposits to or payments from the Collection
Account (or giving instructions regarding the same) in accordance with this
Agreement. Upon any such waiver of a past default, such default shall cease to
exist, and any Administrator Default arising therefrom shall be deemed to have
been remedied for every purpose of this Agreement. No such waiver shall extend
to any subsequent or other default or impair any right consequent thereto.

        Section 2.9A. Sub-Administrators.

        (a) The Administrator, as an independent contractor, shall administer
the Trust Property and shall have full power and authority, acting alone, to do
any and all things in connection with such administration which the
Administrator may deem necessary or desirable and consistent with the terms of
this Agreement. The Administrator may enter into agreements with affiliated
entities for purposes of carrying out any or all of the Administrator's duties
hereunder. The Administrator shall give notice to the Note Insurer of the
appointment of any such affiliate. Any such agreement shall be consistent with
and not violate the provisions of this Agreement.

        (b) Notwithstanding any such agreement, the Administrator shall remain
obligated and primarily liable to the Trustee, the Noteholders, the Subordinated
Certificateholders and the Note Insurer for the administering of the Trust
Property in accordance with the provisions of this Agreement without diminution
of such obligation or liability by virtue of such agreements or arrangements to
the same extent and under the same terms and conditions as if the Administrator
alone were servicing the administering the Trust Property.

        Section 2.10A. Cash Flow Certificates.

        Not more than 60 and not less than 30 days prior to each December 31,
commencing with December 31, 2001, the Administrator shall cause the Cash Flow
Consultant to prepare and deliver to the Administrator, the Collateral Agent and
the Trustee, with a copy to the Depositors, the Note Insurer and the Rating
Agencies, a Cash Flow Certificate for each of the Underlying Trusts. Each Cash
Flow Certificate shall be in substantially the form set forth in Exhibit H
hereto and shall set forth, the maximum amount that may be withdrawn from the
applicable Underlying Trust and remitted to the Collateral Agent no later than
three Business Days prior to the January 2 and July 2 next succeeding the date
of such Cash Flow Certificate (the "Withdrawal Amounts") and shall set forth the
assumptions and methodology used in calculating such Withdrawal Amounts. Not
later than 5 Business Days following the Administrator's receipt of a Cash Flow
Certificate, the Administrator shall submit to the trustee of the applicable
Underlying Trust the related Cash Flow Certificate along with a request that
each such trustee remit to the Collateral Agent, no later than three Business
Days prior to the related January 2 and July 2 the applicable Withdrawal Amount.

        The Administrator shall provide written directions to the Trustee to
take such actions, including but not limited to filing Uniform Commercial Code
Financing Statements and continuation statements, as the Administrator
determines to be necessary to ensure that the security interest created pursuant
to Section 2.5 would be deemed a perfected security interest of first priority
under applicable law and will be maintained as such throughout the term of this
Agreement.

Documents to the contrary, the Administrator shall be responsible for promptly
notifying the Trustee, the Note Paying Agent and the Certificate Paying Agent in
the event that any withholding tax is imposed on the Trust's payments (or
allocations of income) to a Noteholder or Subordinated Certificateholder. Any
such notice shall be in writing and specify the amount of any withholding tax
required to be withheld by the Trustee, the Note Paying Agent or the Certificate
Paying Agent pursuant to such provision.

        (d) The Administrator shall perform any other duties expressly required
to be performed by the Administrator under this Agreement or any of the Related
Documents.

        (e) In carrying out the foregoing duties or any of its other obligations

otherwise deal with any of its affiliates; provided, however, that the terms of
any such transactions or dealings shall be in accordance with any directions
received from the Trust or the Trustee and shall be, in the Administrator's
opinion, no less favorable to the Trust in any material respect than could have
been obtained with other non-affiliated parties.

        (f) The Administrator shall furnish to the Trustee from time to time

subsequently disposed of by the Trustee (or the Note Registrar or the
Certificate Registrar, as the case may be, on behalf of the Trustee) in
accordance with its customary practice.

        (g) No service charge shall be made for any registration of transfer or
exchange of Notes or Subordinated Certificates, but the Note Registrar or the
Certificate Registrar, as applicable, may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
such transfer or exchange.

        (h) Neither the Trustee, the Note Registrar nor the Certificate
Registrar shall be responsible for determining compliance with the restrictions
on transfer in this Agreement provided it receives the documents referred to
above in this Section 3.6.

        (i) The Holder (and Beneficial Owner) of a Note or the Holder of a
Subordinated Certificate effecting transfer thereof shall be deemed to indemnify
each of the Trustee, the Collateral Agent, the Note Registrar and the Note
Paying Agent or the Certificate Registrar and the Certificate Paying Agent, as
applicable, each in its individual and fiduciary capacities, the Depositors, the
Administrator, the Note Insurer and the Subordinated Certificateholders against
any liability that may result if the transfer is not exempt from the
registration requirements of the Securities Act of 1933. Each Noteholder (and
each Beneficial Owner) or Subordinated Certificateholder shall be deemed by its
acceptance and holding of its Note or Subordinated Certificate to agree that
none of the Depositors, the Trustee, the Collateral Agent, the Note Registrar,
the Certificate Registrar, the Note Insurer, the Subordinated Certificateholder,
the Note Paying Agent or the Certificate Paying Agent is under an obligation to
register the Notes or the Subordinated Certificates under the Securities Act of
1933 or any other securities law.

        (j) Any transfer in violation of this Section 3.6 (whether pursuant to a
purchase, a transfer resulting from a default under a secured lending agreement
or otherwise) to a nonresident alien or a foreign corporation shall be deemed to
be of no legal force or effect whatsoever and any nonresident alien or foreign
corporation shall not be deemed to be a Holder for any purpose hereunder.

        (k) It is intended that the Book-Entry Notes be registered so as to
participate in a global book entry system with the Depository, as set forth
herein. The Book-Entry Notes shall be initially issued in the form of a single
fully registered Note. Upon initial issuance, the ownership of the Book-Entry
Notes shall be registered in the Note Register in the name of Cede & Co., or any
successor thereto, as nominee for the Depository.

        The Trustee and the Note Paying Agent in the name and on behalf of the
Trust and the Note Paying Agent shall have power and authority and are hereby
authorized and empowered to execute and deliver the Depository Representation
Letter with the Depository.

        With respect to the Book-Entry Notes registered in the Note Register in
the name of Cede & Co., as nominee of the Depository, the Note Paying Agent
shall have no responsibility or obligation to Direct or Indirect Participants or
beneficial owners for which the Depository holds Book-Entry Notes from time to
time as a Depository. Without limiting the immediately preceding sentence, the
Note Paying Agent shall have no responsibility or obligation with respect to (i)
the accuracy of the records of the Depository, Cede & Co., or any Direct or
Indirect Participant with respect to the ownership interest in the Book-Entry
Notes, (ii) the delivery to any Direct or Indirect Participant or any other
Person, other than a Holder of a Note as shown in the Note Register, of any
notice with respect to the Notes or (iii) the payment to any Direct or Indirect
Participant or any other Person, other than a Holder of a Note as shown in the
Note Register, of any amount with respect to any distribution of principal or
interest on the Notes. No Person other than a Holder of a Note as shown in the
Note Register shall receive a certificate evidencing such Note.

        Upon delivery by the Depository to the Note Registrar of written notice
to the effect that the Depository has determined to substitute a new nominee in
place of Cede & Co., and subject to the provisions hereof with respect to the
payment of interest by the mailing of checks or drafts to the Holders of Notes
as shown in the Note Register on a Record Date, the name "Cede & Co." in this
Agreement shall refer to such new nominee of the Depository. The Note Registrar
shall provide a copy of such written notice to the Note Paying Agent.

        (l) In the event that (i) the Depository or the Administrator advise the
Note Registrar in writing that the Depository is no longer willing or able to
discharge properly its responsibilities as nominee and depository with respect
to the Book-Entry Notes and neither the Depositors nor the Note Registrar is
able to locate a qualified successor or (ii) the Depositors at their sole option
elect to terminate the book-entry system through the Depository, the Book-Entry
Notes shall no longer be restricted to being registered in the Note Register in
the name of Cede & Co. (or a successor nominee) as nominee of the Depository. At
that time, the Depositors may determine that the Book-Entry Notes shall be
registered in the name of and deposited with a successor depository operating a

                                       44

<PAGE>

global book-entry system, as may be acceptable to the Administrator and at their
expense, or such depository's agent or designee but, if the Administrator does
not select such alternative global book-entry system, then the Book-Entry Notes
may be registered in whatever name or names Holders of Notes shall designate and
Definitive Notes issued, in accordance with the provisions hereof. The Note
Registrar shall provide a copy of such written notice to the Note Paying Agent.

        (m) Notwithstanding any other provision of this Agreement to the
contrary, so long as any Book-Entry Note is registered in the name of Cede &
Co., as nominee of the Depository, all distributions of principal or interest on
such Book-Entry Notes and all notices with respect to such Book-Entry Notes
shall be made and given, respectively, in the manner provided in the Depository
Representation Letter.

        (n) A Person which becomes the Beneficial Owner of a Book-Entry Note
shall be deemed to make the representations set forth in Exhibit E to the Trust,
the Trustee, the Collateral Agent, the Note Paying Agent, the Note Registrar,
the Note Insurer, the other Noteholders and the Subordinated Certificateholders.

        (o) No offer, sale, transfer or other disposition (including pledge) of
the Subordinated Certificates shall be made to any Person which is, or is
purchasing for, or on behalf of (1) an employee benefit plan, retirement
arrangement, individual retirement account or Keogh plan subject to either Title
I of the Employee Retirement Income Security Act of 1974, as amended, or Section
4975 of the Internal Revenue Code of 1986, as amended, or (2) an entity
(including an insurance company general account) whose underlying assets include
plan assets by reason of any such plan's arrangements or account's investment in
any such entity.

        Section 3.7. Mutilated, Destroyed, Lost or Stolen Notes or Subordinated
Certificates.

        If (a) any mutilated Note or Subordinated Certificate is surrendered to
the Note Registrar or the Certificate Registrar, as the case may be, or (b) the
Note Registrar or the Certificate Registrar, as the case may be, receives
evidence to its satisfaction of the destruction, loss or theft of any Note or
Subordinated Certificate and there is delivered to the Note Registrar or the
Certificate Registrar, as the case may be, such security or indemnity as may be
required by it to save it harmless, then, in the absence of written notice to
the Registrar that such Note or Subordinated Certificate has been acquired by a
bona fide purchaser, the Trustee on behalf of the Trust shall execute, and the
Note Registrar or the Certificate Registrar, as the case may be, shall
authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Note or Subordinated Certificate, a new Note or
Subordinated Certificate of like original Principal Amount or Percentage
Interest. In connection with the issuance of any new Note or Subordinated
Certificate under this Section 3.7, the Note Registrar or the Certificate
Registrar, as the case may be, may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee
and the Note Registrar or the Certificate Registrar, as the case may be)
connected therewith. Any duplicate Note or Subordinated Certificate issued
pursuant to this Section 3.7 shall be duly authorized, validly issued, and
entitled to the benefits of this Agreement and shall constitute conclusive
evidence of ownership, as if originally issued, whether or not the lost, stolen
or destroyed Note or Subordinated Certificate shall be found at any time.

        Section 3.8. Persons Deemed Noteholders and Subordinated
Certificateholders.

        Prior to due presentation of a Note or Subordinated Certificate for
registration of transfer, the Trustee, the Collateral Agent, the Note Paying
Agent, the Note Registrar or the Certificate Paying Agent and the Certificate
Registrar, as the case may be and their agents may treat the person in whose
name any Note or Subordinated Certificate is registered as the owner thereof for
the purpose of receiving payments or distributions pursuant to Section 4.2 and
for all other purposes whatsoever, and none of the Trustee, the Collateral
Agent, the Note Paying Agent, the Note Registrar or the Certificate Paying Agent
and the Certificate Registrar, as the case may be, or any of their agents shall
be affected by any notice to the contrary.

        Section 3.9. Access to List of Noteholders' and Subordinated
Certificateholders' Names and Addresses.

        (a) The Note Registrar shall furnish or cause to be furnished to the
Depositors, the Administrator, the Holder of the Special Interest or one or more
Subordinated Certificateholders holding not less than 25% of the Percentage
Interest of the Subordinated Certificates within 15 days after receipt by the
Note Registrar of a written request therefor, a list of the names and addresses
of the Noteholders as of the most recent Record Date for payments to
Noteholders. If three or more Noteholders, or one or more Noteholders holding
not less than 25% of the aggregate Principal Amount of the Notes (hereinafter
referred to as "Applicants"), apply in writing to the Note Registrar, and such
application states that the Applicants desire to communicate with other
Noteholders with respect to their rights under this Agreement or under the
Notes, then the Note Registrar shall, within five Business Days after the
receipt of such application, afford such Applicants access, during normal
business hours, to the current list of Noteholders. Every Noteholder, by
receiving and holding a Note, agrees that none of the Depositors, the Trustee,
the Note Insurer, the Note Paying Agent and Note Registrar or any of their
agents shall be held accountable by reason of the disclosure of any such
information as to the names and addresses of the Noteholders under this
Agreement, regardless of the source from which such information was derived.

        (b) The Certificate Registrar shall furnish or cause to be furnished to
the Depositors, the Administrator, or the Holder of the Special Interest within
15 days after receipt by the Registrar of a written request therefor, a list of
the names and addresses of the Subordinated Certificateholders as of the most
recent Record Date for distributions to Subordinated Certificateholders. If
three or more Subordinated Certificateholders, or one or more Subordinated
Certificateholders holding not less than 25% of the Percentage Interests
(hereinafter referred to as "Applicants"), apply in writing to the Certificate
Registrar, and such application states that the Applicants desire to communicate
with other Subordinated Certificateholders with respect to their rights under

                                       46

<PAGE>

this Agreement or under the Subordinated Certificates, then the Certificate
Registrar shall, within five Business Days after the receipt of such
application, afford such Applicants access, during normal business hours, to the
current list of Subordinated Certificateholders. Every Subordinated
Certificateholder, by receiving and holding a Subordinated Certificate, agrees
that none of the Depositors, the Trustee, the Note Insurer, the Certificate
Paying Agent, the Certificate Registrar or any of their agents shall be held
accountable by reason of the disclosure of any such information as to the names
and addresses of the Subordinated Certificateholders under this Agreement,
regardless of the source from which such information was derived.

        Section 3.10. Disposition by the Holder of the Special Interest.

        On and after the Closing Date, the Holder of the Special Interest shall
retain beneficial and record ownership of Subordinated Certificates representing
at least 1% (but not more than 99%) of the Percentage Interest. To the fullest
extent permitted by applicable law, any attempted transfer of any Subordinated
Certificate that would reduce such interest of the Holder of the Special
Interest below 1% of the Percentage Interest shall be void. The Trust
Certificate representing the 1% Special Interest issued to the Holder of the
Special Interest shall contain a legend stating "TO THE FULLEST EXTENT PERMITTED
BY APPLICABLE LAW, THIS CERTIFICATE IS NOT TRANSFERABLE."

                                   ARTICLE IV
              ADMINISTRATION OF COLLECTION ACCOUNT, RESERVE ACCOUNT
                    AND DISTRIBUTION ACCOUNT; CERTAIN DUTIES

        Section 4.1. Collection Account, Reserve Account and Distribution
Account.

        (a) The Collateral Agent shall establish and maintain the Collection
Account in the name of the Trust, which shall be an Eligible Account and
initially will be a segregated trust account maintained at the Collateral Agent
or an affiliate thereof and shall be entitled "The NELnet Group Trust I
Collection Account."

        The Collateral Agent also shall establish and maintain the Reserve
Account in the name of the Trust, which shall be an Eligible Account and
initially will be a segregated trust account maintained at the Collateral Agent
or an affiliate thereof and shall be entitled "The NELnet Group Trust I Reserve
Account." The Reserve Account will be divided into two sub-accounts. On each
Payment Date, the Collateral Agent will transfer from the Collection Account to
the first sub-account of the Reserve Account the amount, if any, remaining in
the Collection Account on such Payment Date, after giving effect to payments
made pursuant to Section 4.2(a)(i) through (xi), inclusive, until the amount of
cash in the first sub-account of the Reserve Account equals the Specified
Reserve Account Requirement. For the purpose of funding the second sub-account
of the Reserve Account, the Trust shall deliver the Debt Service Reserve Surety
Bond to the Note Paying Agent. If on the Business Day prior to any Payment Date
(other than the first Payment Date), the amount in the Collection Account is
less than the amount to be paid on such Payment Date pursuant to Section
4.2(a)(i) through (vii), inclusive, the Collateral Agent shall withdraw from the
first sub-account of the Reserve Account and deposit in the Collection Account

                                       47

<PAGE>

the lesser of (x) the amount then on deposit in the first sub-account of the
Reserve Account and (y) the amount of such shortfall. If on the Business Day
prior to any Payment Date (other than the first Payment Date) the amount on
deposit in the first sub-account of the Reserve Account would exceed the
Specified Reserve Account Requirement for such Payment Date (after giving effect
to all payments to be made on such Payment Date pursuant to Section 4.2(a) (i)
through (xiii), inclusive), the Collateral Agent shall withdraw from the first
sub-account of the Reserve Account and deposit in the Collection Account an
amount equal to such excess. For purposes of this Agreement, when the Note
Paying Agent is entitled to draw on the second sub-account of the Reserve
Account, the Note Paying Agent shall draw on the Debt Service Reserve Surety
Bond in the manner provided in Section 4.9 of this Agreement.

        The Collateral Agent shall deposit in the Collection Account (within one
Business Day of receipt thereof) all amounts received on account of the
Underlying Residual Rights, any Optional Advances received pursuant to Section
4.8(a) and any Principal Subsidy Payments received pursuant to Section 4.8(b).
In connection therewith, the Depositors and the Administrator shall take, or
cause to be taken, all actions required or permitted under the terms of the
Indentures and the other Underlying Agreements so that amounts entitled to be
received on account of the Underlying Residual Rights and the Maintenance and
Operating Expenses are received in a timely manner to make payments on the
Notes. Such actions shall include, but not be limited to, the procedures set
forth in Section 2.10A.

        The Trustee shall establish and maintain the Distribution Account in the
name of the Trust, which shall be an Eligible Account and initially will be a
segregated trust account maintained at Wilmington Trust Company or an affiliate
thereof and shall be entitled "The NELnet Group Trust I Distribution Account."

        On each Payment Date, the Note Paying Agent shall withdraw all amounts
then on deposit in the Collection Account and apply the funds in the manner set
forth in Section 4.2 of this Agreement. The Note Paying Agent also shall deposit
in the Collection Account, promptly upon receipt thereof, all Surety Bond
Payments and Insured Payments received from the Note Insurer.

        (b) The Trust will possess all right, title and interest in all funds on
deposit from time to time in the Collection Account, the Reserve Account and the
Distribution Account and all proceeds thereof subject to the terms of the
Security Agreement. The Note Paying Agent is authorized to draw upon the
Collection Account and the Reserve Account and the Certificate Paying Agent is
authorized to draw on the Distribution Account for the purposes of making all
payments therefrom required or permitted by this Agreement. If, at any time, the
Collection Account, the Reserve Account or the Distribution Account, ceases to
be an Eligible Account, the Collateral Agent, in the case of the Collection
Account and the Reserve Account, or the Trustee, in the case of the Distribution
Account, shall within five Business Days after a Responsible Officer thereof
shall obtain actual knowledge thereof (or such longer period, not to exceed 30
calendar days, as to which the Rating Agency may consent) establish a new
Collection Account, Reserve Account or Distribution Account, as the case may be,
as an Eligible Account and the Note Paying Agent shall transfer any cash and/or
any investments to such new Collection Account or Reserve Account, as the case
may be, or the Certificate Paying Agent shall transfer any cash and/or
investments to such new Distribution Account.

                                       48

<PAGE>

        (c) All amounts held in the Collection Account and the Reserve Account
shall be invested to the extent permitted by applicable laws, rules and
regulations, by the Collateral Agent at the written direction of the
Administrator in Eligible Investments that are payable on demand or mature not
later than one Business Day prior to the Payment Date to which such amounts
relate. Amounts held in the Distribution Account shall remain uninvested. In the
absence of directions by the Administrator, the Collateral Agent shall invest
all such amounts in Eligible Investments as defined in clause (ii) of the
definition thereof. Investments in Eligible Investments must be made in the name
of the Collateral Agent for the benefit of the Noteholders and the Note Insurer,
and, unless payable on demand at par, such investments may not be sold or
disposed of prior to their maturity. Any investment of funds must be made in
Eligible Investments held by a financial institution with respect to which (a)
such institution has noted the Collateral Agent's interest therein by book entry
or otherwise and (b) a confirmation of the Collateral Agent's interest has been
sent to the Collateral Agent by such institution, provided that such Eligible
Investments are (i) specific certificated securities, and (ii) either (A) in the
possession of such institution or (B) in the possession of a clearing
corporation in New York or Delaware, registered in the name of such clearing
corporation, not endorsed for collection or surrender or any other purpose not
involving transfer, not containing any evidence of a right or interest
inconsistent with the Collateral Agent's interest therein, and held by such
clearing corporation in an account of such institution. Subject to the other
provisions hereof, the Collateral Agent shall have sole control over each such
investment and the income thereon, and any certificate or other instrument
evidencing any such investment, if any, shall be delivered directly to the
Collateral Agent or its agent, together with each document of transfer, if any,
necessary to transfer title to such investment to the Collateral Agent in a
manner which complies with this Section 4.1. All interest, dividends, gains upon
sale and other income from, or earnings on investment of funds in the Collection
Account and the Reserve Account shall constitute part of the Amount Available
and shall be applied on the next Payment Date pursuant to Section 4.2(a) or
4.2(c), as the case may be. All investments of amounts on deposit in the
Collection Account also shall comply with the terms of the Security Agreement.
Neither the Trustee, the Administrator nor the Collateral Agent shall have any
liability for any losses on investments made in accordance with this Section
4.1.

        Section 4.2. Use of Funds in Collection Account, Distribution Account
and Reserve Account.

        (a) On each Payment Date, the Note Paying Agent, based solely upon the
information contained in the Payment Date Report delivered pursuant to Section
4.7, shall apply the sum of (i) the Amount Available, (ii) amounts transferred
from the first sub-account of the Reserve Account pursuant to Section 4.1(a),
and (iii) any Surety Bond Payments and Insured Payments received pursuant to
Section 4.9 in the following order of priority (provided, however, that (A)
Optional Advances may only be used for priorities (i), (ii), (iii), (iv) and (v)
below, (B) Principal Subsidy Payments may only be used for priority (vii) below
and (C) Surety Bond Payments and, prior to the Maturity Date of the Notes,
Insured Payments may only be used for priority (v) below):

<PAGE>

               (i) first, to the Trustee, an amount equal to the accrued and
unpaid Trustee Fee for such period pursuant to Section 6.1;

               (ii) second, to the Collateral Agent, an amount equal to the
accrued and unpaid Collateral Agent Fee for such Payment Date;

               (iii) third, to the Note Insurer, an amount equal to the accrued
and unpaid Note Insurer Premiums for such Payment Date;

               (iv) fourth, to the Administrator, an amount equal to the accrued
and unpaid Administration Fees for such Payment Date;

               (v) fifth, to the Noteholders, the Interest Amount; provided,
however, if the portion of the amount remaining in the Collection Account after
application of clauses (i), (ii), (iii) and (iv) above is less than the Interest
Amount, such remaining amount shall be paid to the Noteholders on a pro rata
basis according to the Principal Amount of the respective Notes held by such
Noteholders;

               (vi) sixth, to the Note Insurer, in respect of amounts owed on
account of any Surety Bond Payments previously made, together with interest
accrued thereon at the rate set forth in the Financial Guaranty Agreement;

               (vii) seventh, to the Noteholders, on a pro rata basis according
to the Principal Amount of the respective Notes held by such Noteholders, an
amount equal to the Principal Payment Amount;

               (viii) eighth, to the Noteholders, on a pro rata basis according
to the Principal Amount of the respective Notes held by such Noteholder, an
amount equal to the Special Principal Payment, if any, for such Payment Date;

               (ix) ninth, to reimburse the Administrator for any unreimbursed
Optional Advances made pursuant to Section 4.8(a);

               (x) tenth, to the Note Insurer, in respect of amounts owed on
account of any Insured Payments previously made, together with interest accrued
thereon at the rate set forth in the Insurance Agreement;

               (xi) eleventh, to the Trustee, any unpaid indemnification
payments required to be made pursuant to Section 5.8;

               (xii) twelfth, to the first sub-account of the Reserve Account
until the amount on deposit therein equals the Specified Reserve Account
Requirement for such Payment Date;

               (xiii) thirteenth, to the Note Insurer, any unpaid Reimbursement
Amounts; and

                                       50

               (xiv) fourteenth, any remainder to Certificate Paying Agent for
deposit in the Distribution Account.

        On each Payment Date, the Certificate Paying Agent shall remit all
amounts it receives pursuant to clause (xiv) above to the Subordinated
Certificateholders according to their respective Percentage Interests.

        (b) If any withholding tax is imposed on the payments or distributions
by the Trust (or allocations of income) to a Noteholder or Subordinated
Certificateholder, such tax shall reduce the amount otherwise distributable to
the Noteholder or Subordinated Certificateholder in accordance with this Section
4.2. The Note Paying Agent or the Certificate Paying Agent, as the case may be,
is hereby authorized to retain from amounts otherwise distributable to the
Noteholders or Subordinated Certificateholders sufficient funds for the payment
of any tax that is legally owed by the Trust. The amount of any withholding tax
so imposed shall be treated as cash paid to such Noteholder or distributed to
such Subordinated Certificateholder at the time it is withheld by the Trust and
remitted to the appropriate taxing authority. If there is a possibility that
withholding tax is payable, the Note Paying Agent or the Certificate Paying
Agent, as the case may be, may in its sole discretion withhold such amounts in
accordance with this Section 4.2(b). If a Noteholder or Subordinated
Certificateholder wishes to apply for a refund of any such withholding tax, the
Note Paying Agent or the Certificate Paying Agent, as the case may be, shall
reasonably cooperate with such Noteholder or Subordinated Certificateholder in
making such claim so long as such Noteholder or Subordinated Certificateholder
agrees to reimburse the Note Paying Agent or the Certificate Paying Agent, as
the case may be, for any out-of-pocket expenses incurred.

        (c) If on the Business Day prior to any Payment Date, the amount in the
Collection Account is less than the amount to be paid on such Payment Date
pursuant to Section 4.2(a)(i), (ii), (iii), (iv) and (v) (such shortfall, the
"Collection Account Shortfall"), the Note Paying Agent shall be entitled to
withdraw from the Reserve Account and deposit in the Collection Account the
lesser of (x) the Debt Service Available Amount and (y) the Collection Account
Shortfall. Such withdrawal from the Reserve Account shall be accomplished by the
Note Paying Agent drawing on the Debt Service Reserve Surety Bond in the manner
provided in Section 4.9 of this Agreement.

        Section 4.3. Method of Payment or Distribution.

        Payments required to be made to Noteholders and distributions required
to be made to Subordinated Certificateholders on any Payment Date shall be made
to each Holder of record on the preceding Record Date either by wire transfer,
in immediately available funds, to the account of each such Holder at a bank or
other entity having appropriate facilities therefor, if such Holder shall have
provided to the Note Paying Agent or the Certificate Paying Agent, as
applicable, appropriate written instructions at least five Business Days prior
to such Payment Date (which may be represented by a single continuing request)
or, if not, by check mailed to such Holder at the address of such Holder
appearing in the Note Register or Certificate Register.

        Moneys hereunder need not be segregated in any manner except to the
extent required by law or by Sections 4.1 or 4.2 and may be deposited under such
general conditions as may be prescribed by law, and neither the Trustee nor the

Subordinated Certificateholder, to enable each Holder to prepare its federal and

relating to the Trust (including a partnership information return, Form 1065),
and make such elections as may from time to time be required or appropriate
under any applicable state or federal statute or rule or regulation thereunder
so as to maintain the Trust's characterization as a partnership for federal
income tax purposes and (iv) collect or cause to be collected any withholding
tax as described in and in accordance with Section 4.2(b) with respect to income
or distributions to Noteholders or Subordinated Certificateholders.

        (b) The Trustee shall sign on behalf of the Trust the tax returns of the
Trust furnished to it in execution form by the Holder of the Special Interest,
unless applicable law requires a Subordinated Certificateholder to sign such
documents, in which case such documents shall be signed by the Holder of the
Special Interest. The Holder of the Special Interest shall be the "tax matters
partner" of the Trust pursuant to the Code and shall sign on behalf of the Trust
the tax returns of the Trust.

        Section 4.6. Optional Redemption of Notes.

        (a) On any day following the Payment Date on which the outstanding
Principal Amount of the Notes equals 10% or less of the original Principal
Amount of the Notes, the Administrator shall have the option to purchase all of
the Underlying Residual Rights and the Maintenance and Operating Expenses. To
exercise such option the Administrator shall deposit into the Collection Account
an amount equal to the sum of (i) the Principal Amount of the Notes, plus any
unpaid interest thereon through the date of redemption, and (ii) any
unreimbursed Surety Bond Payments and Insured Payments, any amounts due and
owing to the Note Insurer under the Insurance Agreement and the Financial

        (b) The Note Paying Agent shall mail written notice to the Noteholders
(with a copy to each Rating Agency and the Note Insurer) specifying (i) the date
upon which the final payment with respect to the Notes shall be made upon
presentation and surrender of the Notes at the office of the Note Paying Agent
therein specified, (ii) the amount of any such final payment and (iii) that the

being made only upon presentation and surrender of the Notes at the office of

                                       52

<PAGE>

the Note Paying Agent therein specified. Upon the giving of such notice and the
Administrator's making provision for payment of the Notes, the Notes shall be
deemed to be paid and any amounts in the Collection Account and Reserve Account
not required for the payment of the Notes shall be distributable (i) first to
the Note Insurer for any unreimbursed Surety Bond Payments and Insured Payments,
(ii) second, to the Administrator, to the extent of any unreimbursed Optional
Advances, and then (iii) third, to the Certificate Paying Agent for distribution
to the Subordinated Certificateholders according to their respective Percentage
Interests. The Note Paying Agent shall cause to be paid to Noteholders the final
payment with respect to the Notes only upon presentation and surrender of the
Notes.

        (c) If all the Noteholders shall not surrender their Notes for
cancellation within six months after the date specified in the above-mentioned
written notice, the Note Paying Agent shall give a second written notice to the
remaining Noteholders (with a copy to each Rating Agency and the Note Insurer)
to surrender their Notes for cancellation and receive the final payment with
respect thereto. If within one year after the second notice all the Notes shall
not have been surrendered for cancellation, the Note Paying Agent may take
appropriate steps, or may appoint an agent to take appropriate steps, to contact
the remaining Noteholders concerning surrender of their Notes, and the cost
thereof shall be paid out of the funds and other assets that remain subject to
this Agreement. Subject to applicable escheat laws, any funds remaining in the
Trust which are payable to Noteholders after the Note Paying Agent shall have
taken such measures shall be distributed by the Note Paying Agent to the
Certificate Paying Agent for distribution to the Subordinated Certificateholders
(but only upon termination of this Agreement) and the Noteholders, by acceptance
of their Notes, hereby waive any rights with respect to such funds against the
Trust, the Trustee, the Collateral Agent, the Note Paying Agent, the Note
Insurer or the Certificate Paying Agent and shall look only to the Subordinated
Certificateholders.

        Section 4.7. Reports.

        (a) No later than each Payment Date, the Note Paying Agent, based solely
from the information provided by the Administrator, shall prepare a "Payment
Date Report" substantially in the form of Exhibit D attached hereto and shall
provide such Payment Date Report (together with copies of each report or notice,
if any, furnished to the Note Paying Agent by the Trustee and received by the
Trustee from the trustees of each of the Indentures since the last Payment Date)
to each Noteholder and the Note Insurer on each such Payment Date.

        (b) Within 45 days after the end of each calendar year, the Note Paying
Agent shall furnish or cause to be furnished to each Person who at any time
during the calendar year was the Holder of a Note and the Note Insurer a
statement containing the information with respect to payments of interest on and
principal of such Holder's Note made during such calendar year. Such obligation
of the Note Paying Agent shall be deemed to have been satisfied to the extent
that substantially comparable information shall be provided by the Note Paying
Agent pursuant to any requirements of the Code as from time to time in force.

                                       53

<PAGE>

        (c) Copies of all reports provided by the Note Paying Agent to the
Noteholders shall also be provided to the Rating Agency, the Note Insurer and to
the Certificate Paying Agent for distribution to the Subordinated
Certificateholders.

        (d) The Administrator shall cooperate with the Note Paying Agent in
preparing the reports required to be provided pursuant to this Section 4.7 and,
in such regard, shall provide the Note Paying Agent and the Trustee with all
information necessary to prepare the Payment Date Reports no later than noon New
York City time 3 Business Days prior to the related Payment Date.

        Section 4.8. Optional Advances and Principal Subsidy Payments.

        (a) If for any Payment Date the Interest Amount would exceed the sum of
the aggregate amount in the Collection Account (less the amount to be paid on
such Payment Date pursuant to Section 4.2(a)(i), (ii), (iii) and (iv) above),
the Administrator, in its sole option, may elect to deposit, or have an
affiliate deposit, in the Collection Account (no later than the Business Day
immediately preceding such Payment Date) an amount up to the amount of such
deficiency (such deposit is referred to as an "Optional Advance"). Optional
Advances, if any, shall be recoverable, without interest, by the Administrator
pursuant to Sections 4.2(a)(ix) and 7.3(vii) hereof.

        (b) If for any Payment Date, the amount that will be remaining in the
Collection Account after application of Section 4.2(a)(i), (ii), (iii), (iv),
(v) and (vi) is less than the amount needed to reduce the Recalculated Targeted
Amount of the Notes to the Targeted Balance for such Payment Date, the Trust, in
the Administrator's sole option, may elect to deposit in the Collection Account
(no later than the Business Day immediately preceding such Payment Date) an
amount up to the amount of such deficiency (such deposit is referred to as a
"Principal Subsidy Payment"). Principal Subsidy Payments shall not be
recoverable by the Trust.

        (c) If for any Payment Date an Optional Advance or Principal Subsidy
Payment will be made, the Administrator shall provide written notice thereof to
each Rating Agency.

        Section 4.9. The Policies.

        (a) As soon as possible, and in no event later than 10:00 A.M., New York
time, on the Business Day immediately preceding each Payment Date, the Note
Paying Agent shall furnish the Note Insurer and the Administrator with a
completed notice in the form set forth as Exhibit I hereto (the "Notice") in the
case of a draw under the Note Insurance Policy and a completed demand for
payment in the form set forth as Exhibit J hereto (the "Demand for Payment"), in
the case of a draw under the Debt Service Reserve Surety Bond, which will be
based upon the information set forth in the Administrator's report provided
pursuant to Section 4.7(d), that an Insured Payment or a Surety Bond Payment
will be required with respect to such Payment Date. The Notice or the Demand for
Payment shall specify the total amount of the Insured Payment or Surety Bond
Payment, as the case may be, to be paid on the applicable Payment Date, and
shall constitute a claim for a Surety Bond Payment or an Insured Payment, as the

                                       54

<PAGE>

case may be, pursuant to the Debt Service Reserve Surety Bond or the Note
Insurance Policy, respectively. The Note Insurer shall remit or cause to be
remitted to the Insurance Paying Agent the amount of the Surety Bond Payment or
Insured Payment, as the case may be. Upon receipt of such Surety Bond Payment or
Insured Payment by the Insurance Paying Agent on behalf of the Noteholders, it
shall remit such amounts to the Collateral Agent, who shall deposit such Surety
Bond Payment or Insured Payment, as the case may be, in the Collection Account.

        The Note Paying Agent shall serve as Insurance Paying Agent hereunder
for so long as the Debt Service Reserve Surety Bond or the Note Insurance Policy
shall remain in effect; provided, however, that the Insurance Paying Agent may
be located in another jurisdiction with the written consent of the Note Insurer.
The Insurance Paying Agent shall act as the agent of the Note Paying Agent and
shall (i) pay Surety Bond Payments and Insured Payments received from the Note
Insurer as the Note Paying Agent shall direct and (ii) take such other actions
with respect to the Note Insurer and the Policies as the Note Paying Agent shall
direct. The Note Paying Agent shall act initially as the Insurance Paying Agent.

        The Note Paying Agent shall receive through the Insurance Paying Agent,
as attorney-in-fact of each Holder of Notes, any Surety Bond Payments and
Insured Payments from the Note Insurer and disburse the same to each Holder of
Notes in accordance with the provisions of this Article IV. Surety Bond Payments
and Insured Payments disbursed by the Note Paying Agent from proceeds of the
Policies shall not be considered payment by the Trust nor shall such payments
discharge the obligation of the Trust with respect to such Notes, and the Note
Insurer shall become the owner of the right to receive such unpaid amounts due
from the Trust in respect of the Notes. The Note Paying Agent hereby agrees on
behalf of each Holder of Notes for the benefit of the Note Insurer that it
recognizes that to the extent the Note Insurer makes Surety Bond Payments or
Insured Payments, either directly or indirectly (as by paying through the
Insurance Paying Agent), to the Noteholders, the Note Insurer will be subrogated
to the rights of the Noteholders with respect to such Surety Bond Payment or
Insured Payment, as the case may be, shall be deemed to the extent of the
payments so made to be a registered Noteholder and shall receive available funds
in accordance with Section 4.2 until all such Surety Bond Payments and Insured
Payments by the Note Insurer have been fully reimbursed. To evidence such
subrogation, the Note Paying Agent shall, or shall cause the Note Registrar to,
note the Note Insurer's rights as subrogee on the registration books maintained
by the Note Registrar upon receipt from the Note Insurer of proof of payment of
any Surety Bond Payment or Insured Payment.

        Subordinated Certificateholder, other than as expressly provided for
        herein and in the Related Documents; or

                  (iii) be obligated to exercise any of the rights or powers
        vested in it by this Agreement or any Related Document, or to institute,
        conduct or defend any litigation under this Agreement or otherwise or in
        relation to this Agreement or any Related Document, at the request,
        order or direction of the Noteholders or the Subordinated
        Certificateholders, unless the Noteholders or the Subordinated
        Certificateholders have offered to it security or indemnity satisfactory
        to it against the costs, expenses and liabilities that may be incurred
        by it therein or thereby.

        (d) The right of the Trustee, the Collateral Agent, the Note Registrar,
the Certificate Registrar, the Note Paying Agent, or the Certificate Paying

        (e) Without limiting the generality of the foregoing, the Trustee, the
Collateral Agent, the Note Paying Agent, the Certificate Paying Agent, the Note
Registrar and the Certificate Registrar:

                  (i) may rely on and shall be protected in acting in good faith
        upon the written instructions of the Note Insurer, or the Subordinated
        Certificateholders and such employees and representatives of the Note
        Insurer, or the Subordinated Certificateholders may hereinafter
        designate in writing; and

                  (ii) shall not be liable for any error of judgment, or for any
        act done or step taken or omitted by it, in good faith, or for any
        mistake of fact or law, or for anything that it may do or refrain from
        doing in connection therewith, except in the case of gross negligent
        performance or omission or bad faith.

        Section 5.2. Action Upon Instruction.

        (a) Except as otherwise set forth herein, the Note Insurer or, with the
consent of the Note Insurer, the Subordinated Certificateholders shall have the
exclusive right to direct the actions of the Trustee in the management of the
Trust (including all rights exercisable by the Trust with respect to the Trust
Property) and the actions of the Collateral Agent, the Note Paying Agent, the
Certificate Paying Agent, the Note Registrar and the Certificate Registrar in
the performance of their duties hereunder, in each case, so long as such
directions are not inconsistent with the express terms set forth herein or in
any Related Document.

        (b) None of the Trustee, the Collateral Agent, the Note Paying Agent,
the Certificate Paying Agent, the Note Registrar or the Certificate Registrar
shall be required to take any action hereunder or under any Related Document if
it shall have reasonably determined, or shall have been advised by counsel, that
such action is contrary to the terms hereof or of any Related Document or is
otherwise contrary to law or may result in liability on the part of the Trustee,
the Collateral Agent, the Note Paying Agent, the Certificate Paying Agent, the
Note Registrar or the Certificate Registrar

                                       57

<PAGE>

        (c) None of the Trustee, the Collateral Agent, the Note Paying Agent,
the Certificate Paying Agent, the Note Registrar and the Certificate Registrar
may take any action (a) that is inconsistent with the purposes of the Trust set
forth in Section 2.3 or (b) that, to the actual knowledge of a Responsible
Officer, would result in the Trust's becoming taxable as a corporation for
federal income tax purposes. The Note Insurer and the Subordinated
Certificateholders may not direct taking action that would violate the
provisions of this Section. Subject to the foregoing:

                  (i) Whenever the Trustee receives a request for the Trustee's
        consent to any amendment, modification or waiver with respect to the
        Indentures or any document relating thereto, or receives any other
        solicitation for any action with respect to the Indentures or Underlying
        Residual Rights, the Trustee shall promptly give notice to the
        Noteholders, the Subordinated Certificateholders and the Note Insurer
        requesting instructions as to the course of action to be adopted and, to
        the extent it acts in good faith in accordance with any written
        instructions received from the Holders of a majority of the Principal
        Amount of the Notes, the Holders of a majority of the Percentage
        Interests of the Subordinated Certificates and the Note Insurer, it
        shall not be liable on account of such action to any Person; provided,
        however, that the Trustee shall not vote in favor of or consent to any
        matter (i) which would alter the timing or amount of any payment on the
        Underlying Residual Rights or (ii) which would result in the exchange or
        substitution of any Underlying Residual Rights pursuant to a plan for
        the refunding or refinancing of such Underlying Residual Rights, except
        in each case with the unanimous consent of the Noteholders.

                  (ii) Whenever the Trustee, the Collateral Agent, the Note
        Paying Agent, the Certificate Paying Agent, the Note Registrar or the
        Certificate Registrar, is unable to decide between alternative courses
        of action permitted or required by the terms of this Agreement or any
        Related Document, it shall promptly give notice to the Note Insurer and
        the Subordinated Certificateholders requesting instruction as to the
        course of action to be adopted, and to the extent it acts in good faith
        in accordance with any written instruction received from the Holders of
        a majority of Percentage Interests of the Subordinated Certificates and
        the Note Insurer, it shall not be liable on account of such action to
        any Person.

                  (iii) If the Trustee, the Collateral Agent, the Note Paying
        Agent, the Certificate Paying Agent, the Note Registrar or the
        Certificate Registrar is unsure as to the application of any provision
        of this Agreement or any Related Document or any such provision is
        ambiguous as to its application, or is, or appears to be, in conflict
        with any other applicable provision, or if this Agreement permits any
        determination by it or is silent or is incomplete as to the course of
        action that it is required to take with respect to a particular set of
        facts, it may give notice to the Note Insurer and the Subordinated
        Certificateholders requesting instruction and, to the extent that it
        acts or refrains from acting in good faith in accordance with any
        instruction received from the Holders of a majority of Percentage
        Interests of the Subordinated Certificates and the Note Insurer, it
        shall not be liable, on account of such action or inaction, to any
        Person.

<PAGE>

                  (iv) If the Trustee, the Collateral Agent, the Note Paying
        Agent, the Certificate Paying Agent, the Note Registrar or the
        Certificate Registrar shall not have received appropriate instruction
        within 10 days of any notice given pursuant to the foregoing clauses
        (i), (ii) or (iii) (or within such shorter period of time as reasonably
        may be specified in any such notice or may be necessary under the
        circumstances), it may, but shall be under no duty to, take or refrain
        from taking such action, not inconsistent with this Agreement or the
        Related Documents, as it shall deem to be in the best interests of the
        Noteholders, the Note Insurer and, after the Notes have been paid in
        full, the Subordinated Certificateholders and shall have no liability to
        any Person for such action or inaction.

        Section 5.3. No Duties Except as Specified in This Agreement or in
Instructions; Not Acting in Individual Capacity.

        (a) None of the Trustee, the Collateral Agent, the Note Paying Agent,
the Certificate Paying Agent, the Note Registrar or the Certificate Registrar
shall have any duty or obligation to manage, make any payment with respect to,
register, record, sell, dispose of, or otherwise deal with the Trust Property,
or to otherwise take or refrain from taking any action under, or in connection
with this Agreement, any Related Document, or any document contemplated hereby
or thereby, except as expressly provided by the terms of this Agreement or any
Related Document or in any written instruction received pursuant to Section 5.2;
and no implied duties or obligations shall be read into this Agreement or any
Related Document against the Trustee, the Collateral Agent, the Note Paying
Agent, the Certificate Paying Agent, the Note Registrar or the Certificate
Registrar. None of the Trustee, the Collateral Agent, the Note Paying Agent, the
Certificate Paying Agent, the Note Registrar or the Certificate Registrar shall
have any responsibility to prepare or file any Securities and Exchange
Commission filing for the Trust or to record this Agreement or any Related
Document.

        (b) Except as otherwise expressly provided in this Article V (and
particularly Section 5.1), in accepting the trusts hereby created Wilmington
Trust Company acts solely as Trustee hereunder and not in an individual
capacity, and all Persons having any claim against the Trustee by reason of the
transactions contemplated by this Agreement or any Related Document shall look
only to the Trust Property for payment or satisfaction thereof.

        (c) Notwithstanding anything in this agreement to the contrary in the
event of gross negligence, lack of good faith or willful misconduct (as
determined by a court of competent jurisdiction) of the Collateral Agent, the
Note Registrar or the Note Paying Agent or any of its directors, officers,
agents or employees, the Collateral Agent, the Note Registrar and the Note
Paying Agent and any of its directors, officers, agents and employees shall be
liable to the Note Insurer for the amount of any Insured Payment or Surety Bond
Payment and any charges, fees, costs and expenses the Note Insurer may pay or
incur, including but not limited to attorneys' fees, in connection with the
payment of a claim under the Policies due to the gross negligence, lack of good
faith or willful misconduct of the Collateral Agent, the Note Registrar or the
Note Paying Agent or any of its directors, officers, agents or employees;
provided, however, in no event shall the Trustee, the Collateral Agent, the Note
Paying Agent, the Certificate Paying Agent, the Note Registrar and the

                                       59

Certificate Registrar be liable for special, indirect or consequential loss or
damage of any kind whatsoever (including but not limited to lost profits), even
if the Trustee, the Collateral Agent, the Note Paying Agent, the Certificate
Paying Agent, the Note Registrar and the Certificate Registrar have been advised
of the likelihood of such loss or damage and regardless of the form of action.

Certificate Paying Agent, the Note Registrar and the Certificate Registrar in

duties hereunder with respect to such trusts but only upon the terms of this
Agreement. The Trustee also agrees to disburse all moneys actually received by

and this Agreement. The Trust Company shall not be answerable or accountable
hereunder or under any Related Document under any circumstances, except to the
Trust, the Note Insurer and the Subordinated Certificateholders (i) for its own
willful misconduct, bad faith or gross negligence or (ii) in the case of the
inaccuracy of any representation or warranty contained in Section 5.4 expressly
made by the Trust Company. In particular, but not by way of limitation (and
subject to the exceptions set forth in the preceding sentence):

any Related Document, at the request, order or direction of any of the
Administrator, the Subordinated Certificateholders or Noteholders or otherwise,
unless such Administrator, Subordinated Certificateholders or Noteholders have

                                       63

offered to the Trustee, Collateral Agent, Note Registrar or Note Paying Agent
security or indemnity satisfactory to it against the costs, expenses and
liabilities that may be incurred by the Trustee therein or thereby. The right of
the Trustee, the Certificate Paying Agent, Collateral Agent, Note Registrar,

as a duty, and, except as otherwise provided in Section 5.9 (i) and (ii), the
Trust Company shall not be answerable in the performance of any such act.

        Section 5.10. Trustee, Collateral Agent, Note Registrar and Note Paying
Agent Not Liable for Subordinated Certificates or Underlying Residual Rights.

        The recitals contained herein and in the Subordinated Certificates and
the Notes (other than the signature and authentication of the Trustee on the
Subordinated Certificates) shall be taken as the statements of the Administrator
and the Trustee, Collateral Agent, Note Paying Agent and Note Registrar assume
no responsibility for the correctness thereof. The Trustee, Collateral Agent,
Note Paying Agent and Note Registrar make no representations or warranties as to
the validity or sufficiency of this Agreement, of any Related Document or of the
Subordinated Certificates (other than the signature and authentication of the
Trustee on the Subordinated Certificates) or the Notes, or of any Underlying
Residual Rights or related documents. The Trustee, Collateral Agent, Note Paying
Agent and Note Registrar shall at no time have any responsibility or liability
for or with respect to the legality, validity and enforceability of any Note, or
for or with respect to the sufficiency of the Trust Property or its ability to
generate the payments to be distributed to Subordinated Certificateholders or
the Noteholders.

        Section 5.11. Payments from Trust Property.

        All payments to be made by the Trustee, the Collateral Agent, the Note
Paying Agent or the Certificate Paying Agent under this Agreement or any of the
Related Documents to which the Trust or the Trustee, the Collateral Agent, the

from the income and proceeds of the Trust Property and only to the extent that
the Trustee, the Collateral Agent, the Note Paying Agent or the Certificate
Paying Agent shall have received income or proceeds from the Trust Property to
make such payments in accordance with the terms hereof. None of the Trustee, the
Collateral Agent, the Note Paying Agent or the Certificate Paying Agent or any
successor thereto, in its individual capacity, shall be liable for any amounts
payable under this Agreement or any of the Related Documents to which the Trust,
the Trustee, the Collateral Agent, the Note Paying Agent or the Certificate

        The Trustee shall not have the power, except upon the direction of the
Subordinated Certificateholders with the consent of the Note Insurer, and to the
extent consistent with the Related Documents, to (i) institute proceedings to
have the Trust declared or adjudicated a bankrupt or insolvent, (ii) consent to
the institution of bankruptcy or insolvency proceedings against the Trust, (iii)
file a petition or consent to a petition seeking reorganization or relief on
behalf of the Trust under any applicable federal or state law relating to

pay its debts as they generally become due or (vii) take any action, or cause
the Trust to take any action, in furtherance of any of the foregoing (any of the
above, a "Bankruptcy Action"). So long as the Insurance Agreement remains in
effect and the Note Insurer is not in default of its payment obligations under
either of the Policies, no Subordinated Certificateholder shall have the power
to take, and shall not take, any Bankruptcy Action with respect to the Trust or
direct the Depositors or the Trustee to take any Bankruptcy Action with respect
to the Trust or the Depositors.

        Section 5.13. Actions by Subordinated Certificateholders with Respect to
Bankruptcy.

        The Trustee shall not have the power to commence a bankruptcy action
relating to the Trust without the consent and approval of the Note Insurer, the
unanimous approval of all the Subordinated Certificateholders and the delivery
to the Trustee by each Subordinated Certificateholder of a certificate
certifying that such Subordinated Certificateholder reasonably believes the
Trust to be insolvent.

        Section 5.14. Restrictions on the Subordinated Certificateholders'
Powers.

        The Subordinated Certificateholders shall not direct the Trustee to take
or refrain from taking any action if such action or inaction would be contrary
to any obligation of the Trust or the Trustee under this Agreement or any of the
Related Documents or would be contrary to Section 2.3 of this Agreement nor
shall the Trustee be obligated to follow any such direction, if given.

        Section 5.15. Fiduciary Duties of the Trustee.

        (a) Notwithstanding anything contained herein or in the Related
Documents to the contrary, the duties and responsibilities of the Trustee shall
be limited to those expressly provided for in this Agreement, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities shall
be read into this Agreement or the Related Documents against the Trustee.
Without limiting the generality of the foregoing, the Trustee does not have, and
shall not be deemed to have, any fiduciary relationship with the Collateral
Agent, the Noteholders or the Note Insurer. Rather, this Agreement creates only
an administrative relationship between independent contracting parties to
facilitate the lending and borrowing of funds and the issuance of the Notes.
With respect to the Collateral Agent, the Noteholders and the Note Insurer, the
Trustee undertakes to perform or observe only such of the covenants and
obligations of the Trustee as are expressly set forth in this Agreement, and no
implied covenants or obligations with respect to the Collateral Agent, the

                                       66

<PAGE>

Noteholders or the Note Insurer shall be read into this Agreement or the other
Related Documents against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the Collateral Agent, the Noteholders or the Note Insurer,
and shall not be liable to any such person for the failure of the Trust to
perform its obligations to such persons other than as result of the gross
negligence or willful misconduct of the Trustee in the performance of its
express obligations under this Agreement.

        (b) Whenever in connection with its performance under this Agreement the
Trustee receives inconsistent notices or advice from the Subordinated
Certificateholders, the Noteholders and the Note Insurer, the Trustee need not
take any action in respect with such notices or advice unless and until Trustee
receives (a) indemnification in respect of the matters noted in such notices or
advice to its satisfaction or (b) written direction signed by the Subordinated
Certificateholders, the Note Insurer and the Noteholders in respect thereof.

        (c) In its capacity as Trustee, Wilmington Trust Company owes fiduciary
and other duties (the "Duties") to the Subordinated Certificateholders under the
this Agreement. The Subordinated Certificateholders, the Noteholders and the
Note Insurer acknowledge and agree that the Trustee has only the duties
expressly set forth herein and waive any potential or actual conflict of
interest that may arise as a result thereof. In addition, the Subordinated
Certificateholders acknowledge and agree that their rights under this Agreement
are subordinate to the rights of the Note Insurer and the Noteholders to enforce
the Trustee's duties to the Note Insurer and the Noteholders expressly set forth
herein to the extent inconsistent with the Trustee's Duties to the Subordinated
Certificateholders expressly set forth herein, and agree that in no event shall
the Trustee be liable to the Subordinated Certificateholders as a result of the
foregoing.

                       COMPENSATION OF TRUSTEE AND OTHERS

        For performing its services hereunder, the Trustee shall be entitled to
receive pursuant to Section 4.2(a)(i), the Trustee Fee. The Trustee shall be
entitled to receive from the Holder of the Special Interest reimbursement for
expenses and disbursements of such agents, representatives, experts and counsel
as the Trustee may employ in connection with the exercise and performance of its
rights and duties hereunder. The Trustee shall be responsible for paying any
separate compensation owing to the Certificate Paying Agent and the Certificate
Registrar, which compensation shall be included in any Trustee Fee. For
performing its services hereunder, the Administrator shall be entitled to
receive, pursuant to Section 4.2(a)(iv), the Administration Fee. For performing
its services hereunder and under the Security Agreement, the Collateral Agent
shall be entitled to receive, pursuant to Section 4.2(a)(ii), the Collateral
Agent Fee. The Collateral Agent shall be responsible for paying any separate
compensation owing to the Note Paying Agent and the Note Registrar.

                                     DEFAULT

        Section 7.1. Events of Default.

        "Event of Default," whenever used herein, means any one of the
following:

        (a) default in the payment of the Interest Amount on the Notes for a
period of five Business Days after the related Payment Date; or

        (b) default in payment of the entire unpaid Principal Amount of the
Notes on or before the Maturity Date.

        Section 7.2. Rights Upon an Event of Default.

        (a) If an Event of Default shall have occurred and be continuing, with
the consent of the Note Insurer the Trustee may, or with the consent of the Note
Insurer the Holders of at least 25% in aggregate outstanding Principal Amount of
the Notes (subject to rescission as described below) may, or the Note Insurer
may, declare by written notice to the Subordinated Certificateholders (and the
Trustee, if declared by the Noteholders or the Note Insurer), the entire
Principal Amount of the Notes immediately due, together with accrued interest
thereon. The Subordinated Certificateholders shall have no right to declare an
Event of Default or to make a declaration of acceleration.

        At any time after such a declaration of acceleration with respect to the
Notes has been made and before a judgment or decree for payment of the money due
has been obtained by the Trustee, if there has been deposited in the Collection
Account, either pursuant to collections on the Trust Property or from amounts
deposited with the Collateral Agent by the Subordinated Certificateholders, an
amount sufficient to pay: (i) all sums paid or advanced by the Trustee, the
Collateral Agent, the Note Insurer and the Note Paying Agent hereunder and the
reasonable compensation, expenses and disbursements of the Trustee, the
Collateral Agent, the Note Paying Agent, the Certificate Paying Agent, the Note
Registrar, the Certificate Registrar, the Administrator, the Note Insurer and
their agents and (ii) the Interest Amount with respect to the next Payment Date,
such declaration and its consequences shall be rescinded and annulled.

        (b) If the Notes have been declared due following an Event of Default,
subject to the Security Agreement, the Trustee shall maintain possession of the
Trust Property (or any portion thereof) and continue to apply collections from
the Trust Property as if there had been no declaration of acceleration unless
the Trustee shall be directed by the Note Insurer or, with the consent of the
Note Insurer, the Holders of not less 66 2/3% of the Principal Amount of the
Notes to liquidate the Trust Property, in which case the Trustee shall liquidate
the Trust Property by selling all the assets of the Trust at one or more public
or private sales in any manner permitted by law; provided, however, that neither
the Depositors nor any of their affiliates shall be permitted to purchase any or
all of the assets of the Trust.

                  (iii) third, to the Noteholders, the Interest Amount;
        provided, however, if the remaining money is less than the Interest
        Amount, the remaining money collected shall be distributed on a pro rata
        basis according to the Principal Amount of the respective Notes held by
        such Noteholders;

                  (iv) fourth, to the Noteholders, an amount equal to the
        outstanding Principal Amount of the Notes, provided, however, if the
        remaining money is less than the outstanding Principal Amount of the
        Notes, the remaining money shall be distributed on a pro rata basis
        according to the Principal Amount of the respective Notes held by such
        Noteholders;

                  (v) fifth, to the Note Insurer, amounts due and owing and
        required to be distributed to the Note Insurer pursuant to this
        Agreement, the Insurance Agreement and the Financial Guaranty Agreement;

                  (vi) sixth, to the Administrator, amounts due and owing and
        required to be distributed to the Administrator pursuant to this
        Agreement;

        Subordinated Certificateholders, any remaining money according to their
        respective Percentage Interests.

        Section 7.4. Restrictions on Noteholders' Power.

        No Noteholder will have any right by virtue or by availing itself of any
provisions of this Agreement to institute any suit, action, or proceeding in
equity or at law upon or under or with respect to this Agreement or any Related
Document, unless (a) a Noteholder previously has given to the Trustee a written
notice of default and of the continuance thereof, as provided in this Agreement,
and has obtained the consent of the Note Insurer, and (b) Noteholders

                                       69

the Notes have made written request upon the Trustee to institute such action,
suit or proceeding in its own name as Trustee under this Agreement, have
obtained the consent of the Note Insurer and have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee, for 30 days
after its receipt of such notice, request, and offer of indemnity, has neglected
or refused to institute any such action, suit, or proceeding and during such
30-day period, no request or waiver inconsistent with such written request has
been given to the Trustee pursuant to and in compliance with this Section or
Section 5.2; it being understood and intended, and being expressly covenanted by
each Noteholder with every other Noteholder and the Trustee, that no one or more
Noteholders shall have any right in any manner whatever by virtue or by availing
itself or themselves of any provisions of this Agreement to affect, disturb, or
prejudice the rights of any other Noteholder, or to obtain or seek to obtain
priority over or preference to any other Noteholder, or to enforce any right
under this Agreement, except in the manner provided in this Agreement and for
the equal, ratable, and common benefit of all Noteholders. For the protection
and enforcement of the provisions of this Section 7.4, each and every other
Noteholder and the Trustee will be entitled to such relief as can be given
either at law or in equity.

(x) operate to terminate this Agreement or the Trust, or (y) entitle such
Subordinated Certificateholder to claim an accounting or to take any action or
proceeding in any court for a partition or winding up of all or any part of the
Trust or Trust Property or (z) otherwise affect the rights, obligations and
liabilities of the parties hereto.

the trusts and obligation hereby created by giving written notice thereof to the
Administrator (with a copy to each Rating Agency and the Note Insurer) at least
30 days before the date specified in such notice. Upon receiving such notice of
resignation, the Administrator shall promptly appoint a successor meeting (in
the case of a successor Trustee) the applicable qualifications set forth in
Section 9.1 and in the case of the Note Paying Agent and the Note Registrar,
acceptable to the Note Insurer, by written instrument, in duplicate, one copy of
which instrument shall be delivered to the resigning Trustee, Note Paying Agent,
Certificate Paying Agent, Note Registrar or Certificate Registrar, and one copy
to the successor Trustee, Note Paying Agent, Certificate Paying Agent, Note
Registrar or Certificate Registrar. If no successor Trustee, Note Paying Agent,
Certificate Paying Agent, Note Registrar or Certificate Registrar shall have
been so appointed and have accepted appointment within 30 days after the giving
of such notice of resignation, the resigning Trustee, Note Paying Agent,
Certificate Paying Agent, Note Registrar or Certificate Registrar may petition
any court of competent jurisdiction for the appointment of a successor Trustee,
Note Paying Agent, Certificate Paying Agent, Note Registrar or Certificate
Registrar.

        (b) The Administrator (or the Note Insurer in the case of the Note
Paying Agent and the Note Registrar) may at any time remove the Trustee, the
Note Paying Agent, the Certificate Paying Agent, the Note Registrar or the
Certificate Registrar by giving written notice thereof to the Trustee (with a
copy to each Rating Agency and the Note Insurer) at least 30 days before the
date specified in such notice. Further, if at any time the Trustee shall cease
to be eligible in accordance with the provisions of Section 9.1 and shall fail
to resign after written request therefor by the Administrator or if at any time
the Trustee shall be legally unable to act, or shall be adjudged bankrupt or
insolvent, or a receiver of the Trustee or of its property shall be appointed,
or any public officer shall take charge or control of the Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or
liquidation, then the Administrator or the Note Insurer may remove the Trustee.
If the Administrator shall remove the Trustee, the Note Paying Agent, the
Certificate Paying Agent, the Note Registrar or the Certificate Registrar under
the authority of Section 9.2(b), the Administrator, with the consent of the Note
Insurer in the case of the Trustee, Note Paying Agent or Note Registrar, shall
promptly appoint a successor Trustee, Note Paying Agent, Certificate Paying
Agent, Note Registrar or Certificate Registrar meeting (in the case of a
successor Trustee) the qualification requirements of Section 9.1 by written
instrument, in duplicate, one copy of which instrument shall be delivered to the
outgoing Trustee, Note Paying Agent, Certificate Paying Agent, Note Registrar or
Certificate Registrar so removed, and one copy to the successor Trustee (with a
copy to each Rating Agency and the Note Insurer) and upon any such removal, the
Administrator promptly shall pay all fees and other amounts owed to the outgoing
Trustee, Note Paying Agent, Certificate Paying Agent, Note Registrar or
Certificate Registrar.

        Any resignation or removal of the Trustee, Note Paying Agent,
Certificate Paying Agent, Note Registrar or Certificate Registrar and
appointment of a successor Trustee, Note Paying Agent, Certificate Paying Agent,
Note Registrar or Certificate Registrar (consented to by the Note Insurer in the
case of the Trustee, Note Paying Agent or Note Registrar) pursuant to any of the
provisions of this Section shall not become effective until acceptance of
appointment by the successor Trustee, Note Paying Agent, Certificate Paying
Agent, Note Registrar or Certificate Registrar pursuant to Section 9.3 and (in
the case of removal only) payment of all fees and expenses owed to the outgoing
party.

        Section 9.3. Successor Trustee.

        Any successor Trustee appointed pursuant to Section 9.2 shall execute,
acknowledge and deliver to the Administrator and to its predecessor Trustee an
instrument accepting such appointment under this Agreement, and thereupon the
resignation or removal of its predecessor Trustee shall become effective and
such successor Trustee, without any further act, deed or conveyance, shall
become fully vested with all the rights, powers, duties, and obligations of its
predecessor Trustee under this Agreement, with like effect as if originally
named. The predecessor shall deliver to the successor Trustee all documents and
statements and moneys held by it under this Agreement promptly upon such
predecessor's receipt of all fees and other amounts owing to it; and the
Administrator and the predecessor Trustee shall execute and deliver such
instruments and do such other things as may reasonably be required for fully and
certainly vesting and confirming in the successor Trustee all such rights,
powers, duties, and obligations.

                                       72

<PAGE>

        No successor Trustee shall accept appointment as provided in this
Section unless at the time of such acceptance such successor Trustee shall be
eligible pursuant to Section 9.1.

        Upon acceptance of appointment by a successor Trustee pursuant to this
Section 9.3, the Administrator shall mail notice thereof to all Noteholders,
Subordinated Certificateholders, the Note Insurer and the Rating Agencies. If
the Administrator shall fail to mail such notice within 10 days after acceptance
of appointment by a successor Trustee, the successor Trustee shall cause such
notice to be mailed at the expense of the Administrator.

        Upon the appointment and acceptance of a successor Trustee pursuant to
this Section 9.3, such successor Trustee shall file an amendment to the
Certificate of Trust with the Delaware Secretary of State pursuant to Section
3810 of the Business Trust Statute reflecting the name and principal place of
business of such successor Trustee in the State of Delaware.

        Section 9.4. Merger or Consolidation.

        Any corporation or association into which the Trustee, Note Paying
Agent, Certificate Paying Agent, Note Registrar or Certificate Registrar may be
merged or converted or with which it may be consolidated, or any corporation or
association resulting from any merger, conversion or consolidation to which it
shall be a party, or any corporation or association succeeding to all or
substantially all its corporate trust business, shall be the successor
hereunder; provided such corporation or association shall be eligible pursuant
to Section 9.1 (in the case of the Trustee) and acceptable to the Note Insurer
(in the case of the Note Paying Agent and the Note Registrar), without the
execution or filing of any instrument or any further act on the part of any of
the parties hereto, anything herein to the contrary notwithstanding; provided
further that the Trustee shall mail notice of any merger or consolidation or
conversion affecting it to the Rating Agencies and the Note Insurer at least 30
days prior to the effective date of such merger, consolidation or conversion.

        Section 9.5. Appointment of Co-Trustee or Separate Trustee.

        Notwithstanding any other provision of this Agreement, at any time, for
the purpose of meeting any legal requirements of any jurisdiction in which any
part of the Trust Property may at the time be located, the Trustee shall have
the power and authority and is hereby authorized and empowered to execute and
deliver all instruments to appoint one or more Persons approved by the Trustee
and the Administrator to act as co-trustee, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust Property,
and to vest in such Person, in such capacity, such title to the Trust, or any
part thereof, and, subject to the other provisions of this Section, such powers,
duties, obligations, rights and trusts as the Trustee may consider necessary or
desirable. No co-trustee or separate trustee under this Agreement shall be
required to meet the terms of eligibility as a successor trustee pursuant to
Section 9.1 and no notice of the appointment of any co-trustee or separate
trustee shall be required pursuant to Section 9.1, except that notice of such
appointment shall be given to the Rating Agencies and the Note Insurer.

                                       73

<PAGE>

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

                  (i) all rights, powers, duties, and obligations conferred or
        imposed upon the Trustee shall be conferred upon and exercised or
        performed by the Trustee and such separate trustee or co-trustee jointly
        (it being understood that such separate trustee or co-trustee is not
        authorized to act separately without the Trustee joining in such act),
        except to the extent that under any law of any jurisdiction in which any
        particular act or acts are to be performed, the Trustee shall be
        incompetent or unqualified to perform such act or acts, in which event
        such rights, powers, duties, and obligations (including the holding of
        title to the Trust Property or any portion thereof in any such
        jurisdiction) shall be exercised and performed singly by such separate
        trustee or co-trustee, but solely at the direction of the Trustee;

                  (ii) no trustee under this Agreement shall be personally
        liable by reason of any act or omission of any other trustee under this
        Agreement; and

                  (iii) the Trustee may at any time accept the resignation of or
        remove any separate trustee or co-trustee.

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

        Any separate trustee or co-trustee may at any time appoint the Trustee,
its agent or attorney-in-fact with full power and authority, to the extent not
prohibited by law, to do any lawful act under or in respect of this Agreement on
its behalf and in its name. If any separate trustee or co-trustee shall die,
dissolve, become incapable of acting, resign or be removed, all its estates,
properties, rights, remedies and trusts shall vest in and be exercised by the
Trustee, to the extent permitted by law, without the appointment of a new or
successor trustee.

                            MISCELLANEOUS PROVISIONS

        Section 10.1. Amendment.

        (a) This Agreement may be amended by the Depositors, the Trustee and the
Collateral Agent, with prior written notice to the Rating Agencies and the
consent of the Note Insurer, without the consent of any of the Noteholders or
the Subordinated Certificateholders (i) to cure any ambiguity or defect, (ii) to
correct, supplement or modify any provisions in this Agreement or (iii) for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions in this Agreement or of modifying in any manner the rights of
the Noteholders or the Subordinated Certificateholders; provided, however, in
each case, that such action shall not, as evidenced by an opinion of counsel,
adversely affect in any material respect the interests of any Noteholder or
Subordinated Certificateholder.

        (b) This Agreement may also be amended from time to time by the
Depositors, the Trustee and the Collateral Agent, with the consent of the Note
Insurer and the Holders of a majority of the aggregate outstanding Principal
Amount of the Notes (which consent of any Holder of a Note given pursuant to
this Section or pursuant to any other provision of this Agreement shall be
conclusive and binding on such Holder and on all future Holders of such Note and
of any Note issued upon the transfer thereof or in exchange therefore or in lieu
thereof whether or not notation of such consent is made upon the Note) and to
the extent that the Subordinated Certificates are affected thereby, the consent
of the Holders of a majority of Percentage Interests of the Subordinated
Certificates, for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Agreement, or of modifying
in any manner the rights of the Holders of Notes or the Holders of the
Subordinated Certificates; provided, however, that no such amendment shall (a)
increase or reduce in any manner the amount of, or accelerate or delay the
timing of, payments that shall be required to be made on any Note or the
Interest Rate or (b) change the Event of Default relating to nonpayment of
interest or (c) reduce the aforesaid percentage required to consent to any such
amendment or any waiver hereunder, without the consent of the Holders of all the
Notes then outstanding.

        (c) Prior to the execution of any such amendment or consent, the
Subordinated Certificateholders shall furnish written notification of the
substance of such amendment or consent to each Rating Agency.

        (d) Promptly after the execution of any such amendment or consent, the
Trustee shall furnish written notification of the substance of such amendment or
consent to the Note Registrar for distribution to each Noteholder unless such
parties have previously received such notification.

        (e) It shall not be necessary for the consent pursuant to Section
10.1(b) to approve the particular form of any proposed amendment or consent, but
it shall be sufficient if such consent shall approve the substance thereof. The
manner of obtaining such consents (and any other consents provided for in this
Agreement) and of evidencing the authorization of the execution thereof shall be
subject to such reasonable requirements as the Trustee may prescribe, including
the establishment of record dates.

                                       75

<PAGE>

        (f) Prior to the execution of any amendment to this Agreement, the
Trustee, Note Registrar, Collateral Agent and Note Paying Agent shall be
entitled to receive and rely upon an opinion of counsel, not at its own expense,
stating that the execution of such amendment is authorized or permitted by this
Agreement and that all conditions precedent to the execution and delivery of
such amendment have been satisfied. The Trustee, Note Registrar, Collateral
Agent and Note Paying Agent may, but shall not be obligated to, enter into any
such amendment which affects their own rights, duties or immunities under this
Agreement or otherwise.

        Section 10.2. No Recourse.

        Each Noteholder by accepting a Note acknowledges that its Notes
represent obligations of the Trust only and do not represent interests in or
obligations of the Depositors, the Administrator, the Trustee, the Collateral
Agent, the Note Paying Agent, the Certificate Paying Agent, the Note Registrar,
the Certificate Registrar, the Subordinated Certificateholders, the Holder of
the Special Interest, the Note Insurer or any affiliate of any of the foregoing.
No recourse may be had against such parties or their assets, except as may be
expressly set forth or contemplated in this Agreement, the Notes or the Related
Documents.

        Section 10.3. Governing Law.

        THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF DELAWARE WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF
LAWS THEREOF AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES UNDER THIS
AGREEMENT SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

        Section 10.4. Severability of Provisions.

        If any one or more of the covenants, agreements, provisions or terms of
this Agreement shall be for any reason whatsoever held invalid, then such
covenants, agreements, provisions or terms shall be deemed severable from the
remaining covenants, agreements, provisions or terms of this Agreement and shall
in no way affect the validity or enforceability of the other provisions of this
Agreement or of the Notes or the Subordinated Certificates or the rights of the
Holders thereof.

        Section 10.5. Third-Party Beneficiaries.

        This Agreement shall inure to the benefit of and be binding upon the
parties hereto, the Noteholders, the Note Insurer and the Subordinated
Certificateholders and their respective successors and permitted assigns. The
Noteholders, the Note Insurer, and Indemnified Parties are third party
beneficiaries under this Agreement. The Trustee shall have only the duties
expressly set forth herein with respect to the Noteholders and the Noteholders
shall have the right to enforce the obligations of the Trustee to the same
extent as if they were beneficial owners of the Trust. Except as otherwise
provided in this Agreement, no other Person shall have any right or obligation
hereunder. Nothing contained herein shall be construed to create any fiduciary
obligation of the Trustee to the Note Insurer.

                                       76

<PAGE>

        The Subordinated Certificateholders, Noteholders, and Beneficial Owners
acknowledge and agree that the Trustee has only the duties expressly set forth
herein to the Noteholders under this Agreement and waive any potential or actual
conflict of interest that may arise as a result thereof. In addition, the
Subordinated Certificateholders acknowledge and agree that their rights under
this Agreement are subordinate to the rights of the Noteholders to enforce the
Trustee's duties to the Noteholders expressly set forth herein to the extent
inconsistent with the Trustee's duties to the Subordinated Certificateholders
expressly set forth herein, and agree that in no event shall the Trustee be
liable to the Subordinated Certificateholders as a result of the foregoing.

        Section 10.6. Counterparts.

this Agreement may be executed simultaneously in any number of counterparts,

        Section 10.8. Successors and Assigns.

        All covenants and agreements contained herein shall be binding upon, and
inure to the benefit of, the Administrator, the Depositors, the Holder of the
Special Interest, the Trustee, the Collateral Agent, the Note Paying Agent, the
Certificate Paying Agent, the Note Registrar, the Certificate Registrar, and
their respective successors, each Subordinated Certificateholder and its
successors and permitted assigns, all as herein provided. Any request, notice,
direction, consent, waiver or other instrument or action by a Noteholder or a
Subordinated Certificateholder shall bind the successors and assigns of such
Noteholder or Subordinated Certificateholder.

        Section 10.9. No Petition.

        The Trustee (in its individual capacity and as Trustee), by entering
into this Agreement, each Subordinated Certificateholder, by accepting a Trust
Certificate, and each Noteholder by accepting the benefits of this Agreement,
hereby covenants and agrees that they will not at any time institute against the
Depositors or the Trust, or join in any institution against the Depositors or
the Trust of, any bankruptcy, reorganization, arrangement, insolvency or
liquidation proceedings, or other proceedings under any United States Federal or
state bankruptcy or similar law in connection with any obligations relating to
the Subordinated Certificates, the Notes, this Agreement or any of the Related
Documents.

        Section 10.10. Headings.

        The headings of the various Articles and Sections herein are for
convenience of reference only and shall not define or limit any of the terms or
provisions hereof.

        Section 10.11. Administrator.

        In carrying out its duties hereunder, the Administrator is acting on
behalf of the Trust. The Administrator is authorized and empowered to execute,
prepare, file and/or deliver in the name and on behalf of the Trust all such
documents, reports, filings, tax returns, instruments, certificates and opinions
as it shall be the duty of the Trust to prepare, file or deliver pursuant to the
Related Documents. Upon written request of the Administrator, the Trustee on
behalf of the Trust shall execute and deliver to the Administrator a power of
attorney appointing the Administrator the Trust's agent and attorney-in-fact to
execute, prepare, file and deliver all such documents, reports, filings, tax
returns, instruments, certificates and opinions.

        Section 10.12. Furnishing Information.

        For so long as any of the Notes or Subordinated Certificates are
outstanding and are "restricted securities" within the meaning of Rule 144(a)(3)
of the Securities Act of 1933, as amended (the "Securities Act"), (1) the
Administrator will provide or cause to be provided to any Holder of such Notes
or Subordinated Certificates and any prospective purchaser thereof designated by
such a Holder, upon the request of such Holder or prospective purchaser, the

                                       78

<PAGE>

information required to be provided to such Holder or prospective purchaser by
Rule 144A(d)(4) under the Securities Act; and (2) the Administrator shall update
such information from time to time in order to prevent such information from
becoming false and misleading and will take such other actions as are necessary
to ensure that the safe harbor exemption from the registration requirements of
the Securities Act under Rule 144A is and will be available for resales of such
Notes or Subordinated Certificates conducted in accordance with Rule 144A.

        Section 10.13. Amendments to Underlying Agreements; Underlying Trusts
Not to Issue Additional Securities.

        For so long as any of the Notes are outstanding, the Administrator shall
provide the Rating Agencies, the Note Insurer, the Trustee and the Collateral
Agent with prior written notice (A) of any proposed amendment to or supplement
of (i) an Indenture, (ii) any other Underlying Agreement, or (iii) any other
contract or agreement to which a Depositor is a party or which was assigned to a
Depositor relating to the servicing of student loans included in the Underlying
Trusts or (B) if the Administrator, on behalf of the Trust, wishes to exercise
an optional redemption for some or all of the bonds issued under the MELMAC
Indenture (the "Underlying MELMAC Bonds"), or the notes issued under the NELNET
Indenture (the "Underlying NELNET Bonds"). Neither Depositor (or, with respect
to the Indentures and the other Underlying Agreements, the Administrator, on
behalf of the Trust) shall consent to any such amendment or supplement, or
exercise an optional redemption for some or all of the Underlying Bonds, unless
the Note Insurer provides its written consent (and, in the case of an optional
redemption of the Underlying Bonds, the holders of all the Subordinated
Certificates, other than the Holder of the Special Interest, provide their
written consent) and S&P indicates that such amendment, supplement or redemption
would not cause it to lower or withdraw the rating then assigned by it to the
Notes (without giving effect to the Note Insurance Policy). Further, neither
Depositor may enter into or consent to any amendment of or supplement to the
Indentures on the other Underlying Agreements without the consent of the Trust
(which consent may be given by the Administrator on behalf of the Trust). Prior
to entering into such amendment or supplement, or prior to optionally redeeming
the Underlying Bonds, the Administrator shall provide the Trustee and the Note
Insurer with a certificate, signed by its president or a vice president,
attesting that such action has occurred. In no event, however, shall a Depositor
(or, with respect to the Indentures and the other Underlying Agreements, the
Administrator on behalf of the Trust) consent to any such amendment or
supplement that would result in additional servicing or other compensation being
paid, or student loans being acquired for premiums greater than permitted, under
the agreements listed in (i) through (iv) above as in effect on the date hereof
if, as of the Payment Date immediately prior to the effective date of such
amendment or supplement, the Recalculated Targeted Amount of the Notes exceeds
the Targeted Balance for such Payment Date. Notwithstanding the foregoing, the
provisions of this Section 10.13 shall not apply to (i) any mandatory redemption
of Underlying Bonds or (ii) any redemption of Underlying Bonds resulting from an
Underlying Trust's inability to acquire Eligible Loans (as defined in the
Indentures) during the applicable acquisition and recycling periods.

                                       79

<PAGE>

        Until the Principal Amount of the Notes has been reduced to zero and the
Noteholders have received all amounts to which they are entitled under this
Trust Agreement, neither Depositor will permit the respective Underlying Trust
to issue any additional notes, bonds or other securities or change the mode used
to calculate interest on the Underlying Bonds (I.E., from an auction rate to a
fixed rate or a variable rate).

        Section 10.14. The Note Insurer.

        Any right conferred to the Note Insurer hereunder shall be suspended
during any period in which the Note Insurer is in default in its payment
obligations under the Debt Service Reserve Surety Bond or the Note Insurance
Policy. At such time as the Notes are no longer outstanding hereunder, and no
amounts owed to the Note Insurer hereunder, under the Insurance Agreement and
under the Financial Guaranty Agreement remain unpaid, the Note Insurer's rights
hereunder shall terminate.

        Section 10.15. Security Agreement.

        Each Noteholder by becoming an owner of a Note (and each Beneficial
Owner) and each Subordinated Certificateholder acknowledges that the Trust has
pledged to the Note Insurer a security interest in the Underlying Residual
Rights and the other Trust Property and that, unless the Note Insurer is in
default in its payment obligations under the Debt Service Reserve Surety Bond or
the Note Insurance Policy, upon the occurrence of a Pledgor Default (as defined
in the Security Agreement) the Note Insurer may exercise certain rights with
respect to the Underlying Residual Rights and the other Trust Property.

                                       80

        IN WITNESS WHEREOF, the Depositors, the Administrator, the Trustee,
Certificate Registrar and Certificate Paying Agent and the Collateral Agent,
Note Registrar and Note Paying Agent have caused this Trust Agreement to be duly
executed by their respective officers as of the day and year first above
written.

                                       Authorized Officer

        THE NELNET GROUP TRUST I (the "Trust") hereby promises to pay to the
Registered Holder named above, or registered assigns, from the Trust Property,
the Initial Principal Amount specified above and interest on the unpaid
Principal Amount of this Note at the Interest Rate specified above until this
Note shall have been paid in full.

        The Trust was created pursuant to a Trust Agreement dated as of April 1,
2001 (the "Trust Agreement"), among MELMAC LLC, as a depositor, NELNET Student
Loan Corporation-1, as a depositor (the "NELNET Depositor" and together with
MELMAC LLC, the "Depositors"), NELnet, Inc., as administrator (the
"Administrator"), Wilmington Trust Company, as Trustee (the "Trustee"), and the
Chase Manhattan Bank, as Collateral Agent, Note Registrar and Paying Agent, a
summary of certain of the pertinent provisions of which is set forth below. To
the extent not otherwise defined herein, the capitalized terms used herein have
the meanings assigned to them in the Trust Agreement.

        This Note is one of the duly authorized notes issued pursuant to the
Trust Agreement and designated as 6.34% Student Loan Interest Margin Securities
(the "Notes"). The Trust is also issuing Subordinated Certificates (the
"Subordinated Certificates"). This Note is issued under and is subject to the
terms, provisions and conditions of the Trust Agreement which is incorporated
herein by reference and to which the holder of this Note by virtue of the
acceptance hereof assents and by which such holder is bound. Payments with
respect to the Notes are made solely from the assets of the Trust, which include
(as more fully described in the Trust Agreement): (i) the right to receive the
residual cash-flow (the "Underlying Residual Rights") from two master trust
estates established under two underlying Indentures, (ii) the NELNET Depositor's
right to receive certain maintenance and operating expenses and (iii) the
Collection Account, Reserve Account and Distribution Account established under
the Trust Agreement (collectively, the "Trust Property"). The Notes also are
entitled to the benefits of a Debt Service Reserve Surety Bond and Note
Insurance Policy issued by MBIA Insurance Corporation (the "Note Insurer").

        Under the Trust Agreement, there will be paid semi-annually, on the
second Business Day of each January and July, commencing January, 2002 (the
"Payment Date"), to the person in whose name this Note is registered at the
close of business on the second day immediately preceding such Payment Date (the

                                       B-4

<PAGE>

"Record Date"), interest on this Note at the Interest Rate set forth above
(calculated on the basis of a 360-day year of twelve 30-day months) and the
Principal Payment Amount and the Special Principal Payment, if any, to the
extent of the funds available therefor.

        As described above, the entire unpaid Principal Amount of this Note
shall be due and payable on or before the Maturity Date specified above.
Notwithstanding the foregoing, the entire unpaid Principal Amount of the Notes
shall be due and payable on the date on which an Event of Default shall have
occurred and be continuing and the Trustee or the Holders owning at least 25% in
aggregate Principal Amount of the Notes with the consent of the Note Insurer, or
the Note Insurer, have declared the Notes to be immediately due in the manner
provided in the Trust Agreement; provided the Trustee shall maintain possession
of the Trust Property and continue to apply collections therefrom as if there
had been no declaration of acceleration unless the Trustee shall be directed by
the Holders of not less than 66% of the Principal Amount of the Notes with the
consent of the Note Insurer, or the Note Insurer, to liquidate the Trust
Property. All payments with respect to the principal of the Notes shall be made
pro rata to the Holders of the Notes.

        It is the intent and agreement of the Subordinated Certificateholders
and the Noteholders that, for purposes of federal income, state and local income
and franchise and any other income taxes, the Notes will be treated as debt of
the Trust. Each Noteholder, by acceptance of a Note, covenants and agrees to
treat, and to take no action inconsistent with the treatment of, the Notes as
debt for such tax purposes.

        Payments on this Note will be made by the Note Paying Agent by check or
money order mailed to the Noteholder of record in the Note Register without the
presentation or surrender of this Note or the making of any notation hereon, or
by wire transfer, in immediately available funds, to the account of the
Noteholder at a bank or other entity having appropriate facilities therefor, if
the Noteholder shall have provided to the Note Paying Agent appropriate written
instructions at least five Business Days prior to a Payment Date.
Notwithstanding the above, the final payment on this Note will be made after due
notice by the Note Paying Agent of the pendency of such payment and only upon
presentation and surrender of this Note at the office or agency maintained for
that purpose by the Note Paying Agent.

        The Notes do not represent an obligation of, or an interest in, the
Depositors, the Administrator, the Trustee, the Collateral Agent, the Note
Paying Agent, the Note Registrar, the Subordinated Certificateholders, the Note
Insurer or any affiliate of any of them. The Notes are limited in right of
payment to certain collections and recoveries respecting the Trust Property, all
as more specifically set forth in the Trust Agreement. None of the Trustee, the
Collateral Agent, the Note Paying Agent, the Note Registrar, the Depositors, the
Administrator, the Note Insurer or the Subordinated Certificateholders or any
affiliate of any of them shall incur any personal liability in connection
herewith except as provided in the Trust Agreement. A copy of the Trust
Agreement may, upon request, be examined by any Noteholder during normal
business hours at the principal office of the Trustee and of the Note Paying
Agent and at such other places, if any, designated by the Depositors. The Trust
Agreement permits, with certain exceptions therein provided, the amendment

                                       B-5

thereof and the modification of the rights and obligations of the parties
thereto under the Trust Agreement at any time by the Depositors, the Trustee and
the Collateral Agent), with the consent of the Note Insurer, but without the

certain circumstances, all the Notes. Any such consent by the holder of this
Note shall be conclusive and binding on such Holder and on all future holders of
this Note and of any Note issued upon the transfer hereof or in exchange hereof
or in lieu hereof whether or not notation of such consent is made upon this
Notes.

        THIS CERTIFIES THAT ___________, is the registered owner of the above
specified Percentage Interest in THE NELNET GROUP TRUST I (the "Trust").

        The Trust was created pursuant to a Trust Agreement dated as of April 1,
2001 (the "Trust Agreement"), among MELMAC LLC, as a depositor, NELNET Student
Loan Corporation-1, as a depositor (the "NELNET Depositor and together with
MELMAC LLC, the "Depositors"), NELnet, Inc., as administrator (the
"Administrator"), Wilmington Trust Company, as trustee (the "Trustee"), and the
Chase Manhattan Bank as Collateral Agent, Note Registrar and Note Paying Agent,
a summary of certain of the pertinent provisions of which is set forth below. To
the extent not otherwise defined herein, the capitalized terms used herein have
the meanings assigned to them in the Trust Agreement.

        This certificate is one of the duly authorized certificates designated
in the Trust Agreement as Subordinated Certificates (the "Subordinated
Certificates"). The Trust is also issuing 6.34% Student Loan Interest Margin
Securities (the "Notes"). This Subordinated Certificate is issued under and is
subject to the terms, provisions and conditions of the Trust Agreement which is
incorporated herein by reference and to which the holder of this Subordinated
Certificate by virtue of the acceptance hereof assents and by which such holder
is bound. Distributions with respect to the Subordinated Certificates will be
made, but only after payment in full of the Notes, solely from the assets of the
Trust, which include (as more fully described in the Trust Agreement): (i) the
right to receive the residual cash-flow (the "Underlying Residual Rights") from
two master trust estates established under two underlying Indentures, (ii) the
NELNET Depositor's right to receive certain maintenance and operating expenses,
and (iii) the Collection Account, Reserve Account and Distribution Account
established under the Trust Agreement (collectively, the "Trust Property").

        Distributions will be made with respect to the Subordinated Certificates
only to the extent set forth in the Trust Agreement, semi-annually, on the
second Business Day of each January and July, commencing January, 2002 (the
"Payment Date") to the person in whose name this Subordinated Certificate is
registered at the close of business on the second day immediately preceding such
Payment Date (the "Record Date").

        It is the intent and agreement of the Depositors, the Subordinated
Certificateholders and the Noteholders that, for purposes of federal income,
state and local income and franchise and any other income taxes, the Trust will
be treated as a grantor trust or, if not, as a partnership with the Subordinated
Certificateholders being treated as partners in that partnership, and the Notes
will be treated as debt of the Trust. The Holder of this Subordinated
Certificate, by virtue of the acceptance hereof, agrees to treat, and to take no
action inconsistent with the treatment of, the Subordinated Certificates for
such tax purposes as partnership interests in the Trust.

        Distributions on this Subordinated Certificate will be made by the
Certificate Paying Agent by check or money order mailed to the Subordinated
Certificateholder of record in the Certificate Register without the presentation
or surrender of this Subordinated Certificate or the making of any notation
hereon or by wire transfer, in immediately available funds, to the account of
the Subordinated Certificateholder if the Subordinated Certificateholder shall
have provided to the Certificate Paying Agent appropriate written instructions

                                       C-2

<PAGE>

at least five Business Days prior to a Distribution Date. Notwithstanding the
above, the final distribution on this Subordinated Certificate will be made
after due notice by the Certificate Paying Agent of the pendency of such
distribution and only upon presentation and surrender of this Subordinated
Certificate at the office or agency maintained for that purpose by the
Certificate Paying Agent.

        The Subordinated Certificates do not represent an obligation of, or an
interest in, the Depositors, the Administrator, the Trustee, the Collateral
Agent, the Certificate Paying Agent, the Certificate Registrar or any affiliate
of any of them. The Subordinated Certificates are limited in right of
distributions to certain collections and recoveries respecting the Trust
Property, but only after payment of all amounts the Notes are entitled to
receive on a Payment Date, all as more specifically set forth in the Trust
Agreement. None of the Trustee, the Collateral Agent, the Certificate Paying
Agent, the Certificate Registrar, the Depositors, the Administrator or the
Subordinated Certificateholders shall incur any personal liability in connection
herewith except as provided in the Trust Agreement. A copy of the Trust
Agreement may, upon request, be examined by any Subordinated Certificateholder
during normal business hours at the principal office of the Trustee and at such
other places, if any, designated by the Depositors.

        As provided in the Trust Agreement and subject to certain limitations
set forth therein, the transfer of this Subordinated Certificate is registrable
in the Certificate Register upon surrender of this Subordinated Certificate for
registration of transfer at the office or agency of the Certificate Registrar,
accompanied by a written instrument of transfer in form satisfactory to the
Certificate Registrar duly executed by the holder hereof or such holder's
attorney duly authorized in writing, and thereupon one or more new Subordinated
Certificates of authorized denominations shall be issued to the designated
transferee.

        No transfer of this Subordinated Certificate shall be made unless the
Certificate Registrar shall have received a Representation Letter and Affidavit
from the transferee in the form of Exhibit E to the Trust Agreement. The Holder
of this Subordinated Certificate shall indemnify the Trustee, Certificate Paying
Agent the Certificate Registrar in their individual and fiduciary capacities,
the Note Insurer and the Depositors against any liability that may result if the
transfer is not so exempt. The holder of this Subordinated Certificate shall be
deemed by its acceptance and holding of its Subordinated Certificate to agree
that none of the Depositors, the Administrator, the Trustee, the Collateral
Agent, the Certificate Paying Agent, the Note Insurer or the Certificate
Registrar is under an obligation to register this Subordinated Certificates
under the Securities Act of 1933 or any other securities law.

        The recitals contained herein shall be taken as the statements of the
Depositors or the Subordinated Certificateholders, as the case may be, and the
Trustee assumes no responsibility for the correctness thereof. The Trustee makes
no representations as to the validity or sufficiency of this Subordinated
Certificate or of the assignment of the Trust Property or any related document.

Policy (this "Policy"), hereby unconditionally and irrevocably guarantees to any

proportionate share of the Insured Payment. The Insurer's obligations hereunder
with respect to a particular Insured Payment shall be discharged to the extent

Agent, whether or not such funds are properly applied by the Note Paying Agent.

accelerated Insured Payments shall be made regardless of any acceleration of the
Obligations, unless such acceleration is at the sole option of the Insurer.

related to such preference payment, such instruments being in a form
satisfactory to the Insurer, provided that if such documents are received after

received on the following Business Day. Such payments shall be disbursed to the
receiver or trustee in bankruptcy named ' in the final order of the court
exercising jurisdiction on behalf of the Owner and not to any Owner directly
unless such Owner has returned principal or interest paid on the Obligations to
such receiver or trustee in bankruptcy, in which case such payment shall be
disbursed to such Owner.

12:00 noon, New York City time, on the later of the Payment Date on which the
related Deficiency Amount is due or the second Business Day following receipt in

on such Business Day, it will be deemed to be received on the following Business
Day. If any such Notice received by the Fiscal Agent is not in proper form or is

deemed not to have been received by the Fiscal Agent for purposes of this
paragraph, and the Insurer or the Fiscal Agent, as the case may be, shall
promptly so advise the Note Paying Agent and the Note Paying Agent may submit an
amended Notice.

amount held by the Note Paying Agent for the payment of such Insured Payment and

shall in no event be liable to Owners for any acts of the Fiscal Agent or any
failure of the Insurer to deposit, or cause to be deposited, sufficient funds to
make payments due under this Policy.
