and Zions First National Bank, a national banking association, as successor
indenture trustee ("Trustee"), as supplemented by the Series 1999 Supplemental

parties thereto on March 1, 1996 and June 19, 1996 (the "UNIPAC Subservicing

of the Bank to do so, as servicer with respect to certain of the Financed
Eligible Loans and (ii) InTuition, Inc. ("InTuition"), dated as of December 22,
1998 (the "InTuition Subservicing Agreement"), pursuant to which InTuition will
act as subservicer with respect to certain of the Financed Eligible Loans.

<PAGE>

               Subject to the approval of Fitch IBCA, Inc. and Standard &
Poor's, on or prior to the Closing Date (as defined below) (i) the Bank expects
to assign its rights and obligations under the Servicing Agreement, the UNIPAC
Subservicing Agreement and the InTuition Subservicing Agreement to National
Education Loan Network, Inc. ("NelNet" or the "Servicer"), (ii) the Company
expects to enter into a new servicing agreement with NelNet (the "Servicing
Agreement"), and (iii) NelNet excepts to enter into new subservicing agreements
with UNIPAC and InTuition (the "Subservicing Agreements").

               This Agreement, the Loan Sale Agreement, dated as of June 30,
1999, between NHELP-I, Inc. (the "Seller") and the Company (the "Sale
Agreement"), the Servicing Agreement, the Subservicing Agreements, and the

Underwriters of and payment for the Notes shall be made at the office of Kutak

               4. Agreements of the Company. The Company agrees with each of the
Underwriters as follows:

               (a) The Company will prepare a supplement to the Prospectus
setting forth the amount of the Notes covered thereby and the terms thereof not
otherwise specified in the Prospectus, the price at which the Notes are to be
purchased by the Underwriters, either the initial public offering price or the
method by which the price at which the Notes are to be sold will be determined,
the selling concessions and reallowances, if any, and such other information as
the Underwriters and the Company deem appropriate in connection with the
offering of the Notes, and the Company will timely file such supplement to the
prospectus with the SEC pursuant to Rule 424(b) under the Act, but the Company
will not file any amendments to the Registration Statement as in effect with
respect to the Notes or any amendments or supplements to the Prospectus, unless
it shall first have delivered copies of such amendments or supplements to the
Underwriters, or if the Underwriters shall have reasonably objected thereto
promptly after receipt thereof; the Company will immediately advise the
Underwriters or the Underwriters' counsel (i) when notice is received from the
SEC that any post-effective amendment to the Registration Statement has become
or will become effective and (ii) of any order or communication suspending or
preventing, or threatening to suspend or prevent, the offer and sale of the
Notes or of any proceedings or examinations that may lead to such an order or
communication, whether by or of the SEC or any authority administering any state
securities or Blue Sky law, as soon as the Company is advised thereof, and will
use its best efforts to prevent the issuance of any such order or communication
and to obtain as soon as possible its lifting, if issued.

               (b) If, at any time when the Prospectus relating to the Notes is
required to be delivered under the Act, any event occurs as a result of which
the Prospectus as then amended or supplemented would include an untrue statement
of a material fact or omit to state a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or if it is necessary at any time to amend or supplement
the Prospectus to comply with the Act or the Rules and Regulations, the Company
promptly will prepare and file with the SEC, an amendment or supplement to such
Prospectus that will correct such statement or omission or an amendment that
will effect such compliance.

                (c) The Company will immediately inform the Underwriters (i) of
the receipt by the Company of any communication from the SEC or any state
securities authority concerning the offering or sale of the Notes and (ii) of
the commencement of any lawsuit or proceeding to which the Company is a party
relating to the offering or sale of the Notes.

                                       6
<PAGE>

                (d) The Company will furnish to the Underwriters, without
charge, copies of the Registration Statement (including all documents and
exhibits thereto or incorporated by reference therein), the Prospectus, and all
amendments and supplements to such documents relating to the Notes, in each case
in such quantities as the Underwriters may reasonably request.

                (e) No amendment or supplement will be made to the Registration
Statement or Prospectus which the Underwriters shall not previously have been
advised or to which it shall reasonably object after being so advised.

               (f) The Company will cooperate with the Underwriters and with its
counsel in connection with the qualification of, or procurement of exemptions
with respect to, the Notes for offering and sale by the Underwriters and by
dealers under the securities or Blue Sky laws of such jurisdictions as the
Underwriters may designate and will file such consents to service of process or
other documents necessary or appropriate in order to effect such qualification
or exemptions; provided that in no event shall the Company be obligated to
qualify to do business in any jurisdiction where it is not now so qualified or
to take any action which would subject it to service of process in suits, other
than those arising out of the offering or sale of the Notes, in any jurisdiction
where it is not now so subject.

                (g) The Company consents to the use, in accordance with the
securities or Blue Sky laws of such jurisdictions in which the Notes are offered
by the Underwriters and by dealers, of the Prospectus furnished by the Company.

                (h) To the extent, if any, that the rating or ratings provided
with respect to the Notes by the rating agency or agencies that initially rate
the Notes is conditional upon the furnishing of documents or the taking of any
other actions by the Company, the Company shall cause to be furnished such
documents and such other actions to be taken.

                (i) So long as any of the Notes are outstanding, the Company
will furnish to the Underwriters (i) as soon as available, a copy of each
document relating to the Notes required to be filed with the SEC pursuant to the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), or any order
of the SEC thereunder, and (ii) such other information concerning the Company as
the Underwriters may request from time to time.

               (j) If this Agreement shall terminate or shall be terminated
after execution and delivery pursuant to any provisions hereof (otherwise than
by notice given by the Representative terminating this Agreement pursuant to
Section 8 or Section 9 hereof) or if this Agreement shall be terminated by the
Representative because of any failure or refusal on the part of the Company to
comply with the terms or fulfill any of the conditions of this Agreement, the
Company agrees to reimburse the Underwriters for all out-of-pocket expenses
(including fees and expenses of their counsel) reasonably incurred by it in
connection herewith, but without any further obligation on the part of the
Company for loss of profits or otherwise.

               (k) The net proceeds from the sale of the Notes hereunder will be
applied substantially in accordance with the description set forth in the
Prospectus.

                                       7
<PAGE>

                (l) Except as stated in this Agreement and in the Prospectus,
the Company has not taken, nor will it take, directly or indirectly, any action
designed to or that might reasonably be expected to cause or result in
stabilization or manipulation of the price of the Notes to facilitate the sale
or resale of the Notes.

                (m) For a period from the date of this Agreement until the
retirement of the Notes, the Company will deliver to you the annual statements
of compliance and the annual independent certified public accountants' reports
furnished to the Trustee or the Company pursuant to the Servicing Agreement as
soon as such statements and reports are furnished to the Trustee or the Company.

               (n) On or before the Closing Date, the Company shall mark its
accounting and other records, if any, relating to the Financed Eligible Loans
and shall cause the Servicer, UNIPAC and InTuition to mark their respective
computer records relating to the Financed Eligible Loans to show the absolute
ownership by the Trustee, as eligible lender of, and the interest of the Company
in, the Initial Financed Eligible Loans, and from and after each Closing Date
the Company will take, or cause the Servicer, UNIPAC and InTuition to take, as
the case may be, such actions with respect to the respective records of each
with regard to any Additional Acquired Eligible Loans at the time of the
acquisition thereof by the Trustee on behalf of the Company and the Company
shall not take, or shall permit any other person to take, any action
inconsistent with the ownership of, and the interest of the Company in, the
Financed Eligible Loans, other than as permitted by the Basic Documents.

                (o) For the period beginning on the date of this Agreement and
ending 90 days hereafter, after none of the Company and any entity affiliated,
directly or indirectly, with the Company will, without the prior written notice
to the Underwriters, offer to sell or sell notes (other than the Notes)
collateralized by FFELP Loans; PROVIDED, HOWEVER, that this shall not be
construed to prevent the sale of FFELP Loans by the Company.

                (p) If, at the time the Registration Statement became effective,
any information shall have been omitted therefrom in reliance upon Rule 430A
under the 1933 Act, then, immediately following the execution of this Agreement,
the Company will prepare, and file or transmit for filing with the Commission in
accordance with such Rule 430A and Rule 424(b) under the 1933 Act, copies of an
amended Prospectus containing all information so omitted.

               5. Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless each of the Underwriters and each person, if any,
who controls an Underwriter within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, from and against any and all losses, claims,
damages, liabilities and expenses (including reasonable costs of investigation)
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 insofar as such losses, claims, damages,
liabilities or expenses arise out of or are based upon any untrue statement or
omission or alleged untrue statement or omission which has been made therein or
omitted therefrom in reliance upon and in conformity with the information
relating to an Underwriter furnished in writing to the Company by or on behalf
of such Underwriter expressly for use in connection therewith; PROVIDED,
HOWEVER, that the indemnification contained in this paragraph (a) with respect
to any preliminary prospectus shall not inure to the benefit of an Underwriter
(or to the benefit of any person controlling an Underwriter) on account of any
such loss, claim, damage, liability or expense arising from the sale of the of
Notes by an Underwriter to any person if the untrue statement or alleged untrue
statement or omission or alleged omission of a material fact contained in such
preliminary prospectus was corrected in the final Prospectus and such
Underwriter sold Notes to that person without sending or giving at or prior to
the written confirmation of such sale, a copy of the final Prospectus (as then
amended or supplemented) if the Company has previously furnished sufficient
copies thereof to such Underwriter. The foregoing indemnity agreement shall be
in addition to any liability which the Company may otherwise have.

                                       8
<PAGE>

               (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, such 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 except to the extent that the indemnifying
party is materially prejudiced by such omission. 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 the Underwriter or such controlling person and
the indemnifying parties and the 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 the 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 the
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
each 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 indemnified party from all liability arising out
of such claim, action, suit or proceeding.

                                       9
<PAGE>

               (c) Each Underwriter, severally and not jointly, agrees to
indemnify and hold harmless the Company and its directors and officers, and any
person who controls the Company within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, to the same extent as the indemnity from the
Company to the Underwriters set forth in paragraph (a) hereof, but only with
respect to information relating to an Underwriter furnished in writing by or on
behalf of such Underwriter expressly for use in the Registration Statement, the
Prospectus, or any amendment or supplement thereto, or any related preliminary
prospectus. If any action, suit or proceeding shall be brought against the
Company, any of its directors or officers, or any such controlling person based
on the Registration Statement, the Prospectus, or any amendment or supplement
thereto, or any related preliminary prospectus and in respect of which indemnity
may be sought against an Underwriter pursuant to this paragraph (c), such
Underwriter shall have the rights and duties given to the Company by paragraph
(b) above (except that if the Company shall have assumed the defense thereof the
Underwriter shall not be required to do so, but may employ separate counsel
therein and participate in the defense thereof, but the fees and expenses of
such counsel shall be at such Underwriter's expense), and the Company, its
directors and officers, and any such controlling person shall have the rights
and duties given to the Underwriters by paragraph (b) above. The foregoing
indemnity agreement shall be in addition to any liability which the Underwriters
may otherwise have.

               (d) If the indemnification provided for in this Section 5 is
unavailable to an indemnified party under paragraphs (a) or (c) 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 offering 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 an Underwriter on the other shall be deemed to
be in the same proportion as the total net proceeds from the offering of the
Notes (before deducting expenses) received by the Company bear to the total
underwriting discounts and commissions received by such Underwriter. The
relative fault of the Company on the one hand and the Underwriters on the other
hand shall be determined by reference to, among other things, whether the untrue
or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
on the one hand or by an Underwriter on the other hand and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

                                       10
<PAGE>

               (e) The Company and the Underwriters agree that it would not be
just and equitable if contribution pursuant to this Section 5 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 (d) 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 (d) 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 investigating any claim or defending any such action, suit or
proceeding. Notwithstanding the provisions of this Section 5, 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 exceed
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. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

               (f) Any losses, claims, damages, liabilities or expenses for
which an indemnified party is entitled to indemnification or contribution under
this Section 5 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 contained in this Section 5 and the
representations and warranties of the Company and the Underwriters set forth 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, the Company
or any person controlling any of them or their respective directors or officers,
(ii) acceptance of any Notes and payment therefor hereunder, and (iii) any
termination of this Agreement. A successor to the Underwriters, 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 Section 5.

               6. Conditions of the Underwriters' Obligations. The obligations
of the Underwriters to purchase the Notes hereunder are subject to the following
conditions:

                (a) All actions required to be taken and all filings required to
be made by the Company under the Act prior to the sale of the Notes shall have
been duly taken or made. At and prior to the Closing Date, no stop order
suspending the effectiveness of the Registration Statement shall have been
issued and no proceedings for that purpose shall have been instituted or, to the
knowledge of the Company or the Underwriters, shall be contemplated by the
Commission.

                                       11
<PAGE>

               (b) Subsequent to the effective date of this Agreement, there
shall not have occurred (i) any change, or any development involving a
prospective change, in or affecting the condition (financial or other),
business, properties, net worth, or results of operations of the Company, the
Seller, the Servicer, UNIPAC or InTuition not contemplated by the Registration
Statement, which in the opinion of the Representative, would materially
adversely affect the market for the Notes, (ii) any downgrading in the rating of
any debt securities of the Company, a Seller, the Servicer, UNIPAC or InTuition
by any nationally recognized statistical rating organization or any public
announcement that any such organization has under surveillance or review its
rating of any debt securities of the Company, the Seller, the Servicer, UNIPAC
or InTuition (other than an announcement with positive implications of a
possible upgrading, and no implication of a possible downgrading, of such
rating), or (iii) any event or development which makes any statement made in the
Registration Statement or Prospectus untrue or which, in the opinion of the
Company and its counsel or the Underwriters and their counsel, requires the
filing of any amendment to or change in the Registration Statement or Prospectus
in order to state a material fact required by any law to be stated therein or
necessary in order to make the statements therein not misleading, if amending or
supplementing the Registration Statement or Prospectus to reflect such event or
development would, in the opinion of the Representative, materially adversely
affect the market for the Notes.

                (c) You shall have received an opinion addressed to you of Kutak
Rock, in its capacity as counsel to the Company, dated the Closing Date, in form
and substance satisfactory to you and your counsel with respect to the status of
the Company, to each of the Sale Agreement, Servicing Agreement, Indenture,
Auction Agency Agreement, Broker-Dealer Agreement and this Agreement and to the
validity of the Notes and such related matters as you shall reasonably request.
In addition, you shall have received an opinion addressed to you of Kutak Rock,
in its capacity as counsel for the Company, in form and substance satisfactory
to you and your counsel, concerning "true sale," "non-consolidation" and "first
perfected security interest" and certain other issues with respect to the

the Company to the Trustee.

               (d) You shall have received an opinion addressed to you of Kutak
Rock, in its capacity as counsel for the Company, dated the Closing Date, in
form and substance satisfactory to you and your counsel to the effect that the
statements in the Prospectus under the headings "CERTAIN FEDERAL INCOME TAX

statements of matters of law or legal conclusions with respect thereto, have
been prepared or reviewed by such counsel and are correct in all material
respects.

                (e) You shall have received an opinion addressed to you of Kutak
Rock, in its capacity as counsel for the Company, dated the Closing Date, in
form and substance satisfactory to you and your counsel with respect to the
character of the Notes for federal tax purposes.

                (f) You shall have received an opinion addressed to you of
Stroock & Stroock & Lavan LLP, in its capacity as Underwriters' Counsel, dated
the Closing Date, in form and substance satisfactory to you.

                (g) You shall have received an opinion addressed to you of

Company, dated the Closing Date in form and substance satisfactory to you and
your counsel with respect to the Prospectus and the Registration Statement and
certain matters arising under the Trust Indenture Act of 1939, as amended, and
the Investment Company Act of 1940, as amended.

                (h) You shall have received opinions addressed to you of Perry,
Guthery, Haase & Gessford, P.C. in their capacity as counsel to NelNet and
NHELP-1, Inc., each dated the Closing Date and satisfactory in form and
substance to you and your counsel, to the effect that:

                (i) NelNet is a corporation in good standing under the laws of
         the State of Nevada; NHELP-1, Inc. is a corporation in good standing
         under the laws of the State of Nevada; each having the full power and
         authority (corporate and other) to own its properties and conduct its
         business, as presently conducted by it, and to enter into and perform
         its obligations under each of the Servicing Agreement, the Sale
         Agreement and the Subservicing Agreements to which it is a party.

                (ii) The Sale Agreement has been duly authorized, executed and
         delivered by the Seller and the Servicing Agreement and the
         Subservicing Agreements have been duly authorized, executed and
         delivered by NelNet, and each such agreement is the legal, valid and
         binding obligations of the Seller and NelNet, as the case may be,
         enforceable against the Seller and NelNet, as the case may be, in
         accordance with their respective terms, except (x) the enforceability
         thereof may be subject to bankruptcy, insolvency, reorganization,
         moratorium or other similar laws now or hereafter in effect relating to
         creditors' rights and (y) remedy of specific performance and injunctive
         and other forms of equitable relief may be subject to equitable
         defenses and to the discretion of the court before which any proceeding
         therefor may be brought.

                (iii) Neither the execution and delivery by NelNet of the
         Servicing Agreement or the Subservicing Agreements, or the execution by
         the Seller of the Sale Agreement, nor the consummation by NelNet or the
         Seller of the transactions contemplated therein nor the fulfillment of
         the terms thereof by NelNet or the Seller will conflict with, result in
         a breach, violation or acceleration of, or constitute a default under,
         any term or provision of the by-laws of NelNet or the Seller or of any
         indenture or other agreement or instrument to which NelNet or the
         Seller is a party or by which NelNet or the Seller is bound, or result
         in a violation of or contravene the terms of any statute, order or
         regulation applicable to NelNet or the Seller of any court, regulatory
         body, administrative agency or governmental body having jurisdiction
         over NelNet or the Seller.


                                       13
<PAGE>

                (iv) There are no actions, proceedings or investigations pending
         or, to the best of such counsel's knowledge after due inquiry and
         reasonable investigation, threatened against NelNet or the Seller
         before or by any governmental authority that might materially and
         adversely affect the performance by NelNet or the Seller of its
         obligations under, or the validity or enforceability of, the Servicing
         Agreement, the Subservicing Agreements or the Sale Agreement to which
         it is a party.

                (v) Nothing has come to such counsel's attention that would lead
         such counsel to believe that the representations and warranties of
         NelNet contained in the Servicing Agreement, or the Subservicing
         Agreements or the representations and warranties of the Seller
         contained in the Sale Agreement are other than as stated therein.

                (vi) No authorization, approval, or other action by, and no
         notice to or filing with, any governmental authority or regulatory body
         is required (a) for the due execution, delivery and performance by
         NelNet of the Servicing Agreement or the Subservicing Agreements, (b)
         for the due execution, delivery and performance by the Seller of the
         Sale Agreement or (c) for the perfection of the Company's and the
         Trustee's interest in the Student Loans sold pursuant to the Sale
         Agreement or the exercise by the Company (or it permitted assigns) and
         the Trustee of their rights and remedies under the Sale Agreement,
         including specifically the filings of any Uniform Commercial Code
         financing statements, EXCEPT for the execution and delivery of the
         Guarantee Agreements.

                (vii) The Sale Agreement together with the related bill of sale
         and blanket endorsement effects a valid sale to the Trustee of the
         Student Loans to be sold under the Sale Agreement enforceable against
         creditors of, and purchasers from, the Seller.

                (viii) As of the date specified in a schedule to such opinion,
         there were no (a) UCC financing statements naming the Seller as debtor
         or seller and covering any Student Loans to be sold under the Sale
         Agreement or interest therein or (b) notices of the filing of any
         federal tax lien (filed pursuant to Section 6323 of the Internal
         Revenue Code) or lien of the Pension Benefit Guaranty Corporation
         (filed pursuant to Section 4068 of ERISA) covering any Student Loan to
         be sold under the Sale Agreement or interest therein, listed in the
         available records in the respective offices set forth in such schedule
         opposite each such date (which are all of the offices that are
         prescribed under either the internal law of the conflict of law rules
         of the Nebraska UCC as the offices in which filings should be made to
         perfect security interests in Student Loans), except as set forth in
         such schedule.

<PAGE>

                (ix) As of the date of such opinion, by executing the Guarantee
         Agreements and upon execution and delivery of the instruments of
         transfer described in the Sale Agreement and notification of the
         Guarantors and borrowers of the transfer contemplated thereby, and
         assuming that the Trustee is an eligible lender as that term is defined
         in 20 U.S.C. ss.1085(d)(1) of the Higher Education Act of 1965, as
         amended, the Trustee on behalf of the Company will be entitled to the
         benefit of the applicable Guarantor and/or Department of Education
         payments under the Act related to the Student Loans sold from time to
         time under the Sale Agreement, subject to the terms and conditions of
         the Guarantee Agreements and the Act.

                (i) You shall have received an opinion addressed to you of
         counsel to the Trustee, dated the Closing Date and in form and
         substance satisfactory to you and your counsel, to the effect that:

                (i) The Trustee is a national banking association duly organized
         and validly existing under the laws of the United States of America.

                (ii) The Trustee has the full corporate trust power to accept
         the office of indenture trustee under the Indenture and to enter into
         and perform its obligations under the Indenture, the Amendments to the
         Custodian Agreements, the Auction Agency Agreement, the Market Agent
         Agreement and each Guarantee Agreement.

                (iii) The execution and delivery of each of the Indenture, the
         Amendments to the Custodian Agreements, the Auction Agency Agreement,
         the Market Agent Agreement and each Guarantee Agreement, and the
         performance by the Trustee of its obligations under the Indenture, the
         Amendments to the Custodian Agreements, the Auction Agency Agreement,
         the Market Agent Agreement and each Guarantee Agreement, have been duly
         authorized by all necessary action of the Trustee and each has been
         duly executed and delivered by the Trustee.

                (iv) The Indenture, the Amendments to the Custodian Agreements,
         the Auction Agency Agreement, the Market Agent Agreement and each
         Guarantee Agreement constitute valid and binding obligations of the
         Trustee enforceable against the Trustee.

                (v) The execution and delivery by the Trustee of the Indenture,
         the Amendments to the Custodian Agreements, the Auction Agency
         Agreement, the Market Agent Agreement and each Guarantee Agreement do
         not require any consent, approval or authorization of, or any
         registration or filing with, any state or United States Federal
         governmental authority.

                (vi) Each of the Notes has been duly authenticated by the
         Trustee.

                (vii) Neither the consummation by the Trustee of the
         transactions contemplated in the Indenture, the Amendments to the
         Custodian Agreements, the Auction Agency Agreement and each Guarantee
         Agreement nor the fulfillment of the terms thereof by the Trustee will
         conflict with, result in a breach or violation of, or constitute a
         default under any law or the charter, by-laws or other organizational
         documents of the Trustee or the terms of any indenture or other

offering of the Notes on the terms set forth in the Prospectus, as applicable,
or to enforce contracts for the resale of the Notes by the Underwriters. Notice

exceeding seven days in order to effect any required changes in the Registration
Statement or Prospectus or in any other documents or arrangements.

               The principal of the Series 1999 Notes due at its Stated Maturity
        or redemption in whole shall be payable at the Principal Office of the
        Trustee, or such other location as directed by the Trustee, or at the
        Principal Office of its successor in trust upon presentation and
        surrender of the Series 1999 Notes. Payment of interest and principal
        paid subject to a redemption on any Series 1999 Note shall be made to
        the Registered Owner thereof by check or draft mailed on the Interest
        Payment Date by the Trustee to the Registered Owner at his address as it
        last appears on the registration books kept by the Trustee at the close
        of business on the Record Date for such interest payment date, but any
        such interest not so timely paid or duly provided for shall cease to be
        payable to the Registered Owner thereof at the close of business on the
        Record Date and shall be payable to the Registered Owner thereof at the
        close of business on a special record date (a "Special Record Date") for
        the payment of any such defaulted interest. Such Special Record Date
        shall be fixed by the Trustee whenever moneys become available for
        payment of the defaulted interest, and notice of such Special Record
        Date shall be given to the Registered Owners of the Series 1999 Notes
        not less than 10 days prior thereto by first-class mail to each such
        Registered Owner as shown on the Trustee's registration books on the
        date selected by the Trustee, stating the date of the Special Record
        Date and the date fixed for the payment of such defaulted interest.
        Payment of interest to the Securities Depository or its nominee shall,
        and at the written request addressed to the Trustee of any other
        Registered Owner owning at least $1,000,000 principal amount of the
        Series 1999 Notes, payments of interest shall, be paid by wire transfer
        within the United States to the bank account number filed no later than
        the Record Date or Special Record Date with the Trustee for such
        purpose. All payments on the Series 1999 Notes shall be made in lawful
        money of the United States of America.

               (b) Except as otherwise provided in this Section, the Series 1999
        Notes in the form of one global note for each Stated Maturity date shall
        be registered in the name of the Securities Depository or its nominee
        and ownership thereof shall be maintained in book-entry form by the
        Securities Depository for the account of the Agent Members. Initially,
        each Series 1999 Note shall be registered in the name of CEDE & Co., as
        the nominee of The Depository Trust Company. Except as provided in
        subsection (d) of this Section, the Series 1999 Notes may be
        transferred, in whole but not in part, only to the Securities Depository
        or a nominee of the Securities Depository or to a successor Securities
        Depository selected or approved by the Issuer or to a nominee of such
        successor Securities Depository. Each global note shall bear a legend
        substantially to the following effect: "Except as otherwise provided in
        the Indenture, this global note may be transferred, in whole but not in
        part, only to another nominee of the Securities Depository (as defined
        in the Indenture) or to a successor Securities Depository or to a
        nominee of a successor Securities Depository."

               (c) Except as otherwise provided herein, the Issuer and the
        Trustee shall have no responsibility or obligation with respect to (i)
        the accuracy of the records of the Securities Depository or any Agent
        Member with respect to any beneficial ownership interest in the Series
        1999 Notes, (ii) the delivery to any Agent Member, beneficial owner of
        the Series 1999 Notes or other Person, other than the Securities
        Depository, of any notice with respect to the Series 1999 Notes or (iii)
        the payment to any Agent Member, beneficial owner of the Series 1999
        Notes or other Person, other than the Securities Depository, of any


                                       4
<PAGE>

        amount with respect to the principal of or interest on the Series 1999
        Notes. So long as the certificates for the Series 1999 Notes issued
        under this Supplemental Indenture are not issued pursuant to subsection
        (d) of this Section the Issuer and the Trustee may treat the Securities
        Depository as, and deem the Securities Depository to be, the absolute
        owner of the Series 1999 Notes for all purposes whatsoever, including,
        without limitation, (A) the payment of principal of and interest on such
        Series 1999 Notes, (B) giving notices of redemption and other matters
        with respect to such Series 1999 Notes and (C) registering transfers
        with respect to such Series 1999 Notes. In connection with any notice or
        other communication to be provided to the Registered Owners pursuant to
        this Supplemental Indenture by the Issuer or the Trustee with respect to
        any consent or other action to be taken by the Registered Owners, the
        Issuer or the Trustee, as the case may be, shall establish a record date
        for such consent or other action and, if the Securities Depository shall
        hold all of the Series 1999 Notes, give the Securities Depository notice
        of such record date not less than 15 calendar days in advance of such
        record date to the extent possible. Such notice to the Securities
        Depository shall be given only when the Securities Depository is the
        sole Registered Owner.

               (d) If at any time the Securities Depository notifies the Issuer
        and the Trustee that it is unwilling or unable to continue as Securities
        Depository with respect to any or all of the Series 1999 Notes or if at
        any time the Securities Depository shall no longer be registered or in
        good standing under the Securities Exchange Act or other applicable
        statute or regulation and a successor Securities Depository is not
        appointed by the Issuer within 90 days after the Issuer receives notice
        or becomes aware of such condition, as the case may be, subsections (b)
        and (c) of this Section shall no longer be applicable and the Issuer
        shall execute and the Trustee shall authenticate and deliver
        certificates representing the Series 1999 Notes as provided below. In
        addition, the Issuer may determine at any time that the Series 1999
        Notes shall no longer be represented by global certificates and that the
        provisions of subsections (b) and (c) of this Section shall no longer
        apply to the Series 1999 Notes. In such event, the Issuer shall execute
        and the Trustee shall authenticate and deliver certificates representing
        the Series 1999 Notes as provided below. Certificates for the Series
        1999 Notes issued in exchange for a global certificate pursuant to this
        subsection shall be registered in such names and authorized
        denominations as the Securities Depository, pursuant to instructions
        from the Agent Members or otherwise, shall instruct in writing the
        Issuer and the Trustee, and upon which written instructions the Trustee
        may rely without investigation. The Trustee shall promptly deliver such
        certificates representing the Series 1999 Notes to the Persons in whose
        names such Notes are so registered.

<PAGE>

               (a) Mandatory Redemption. Subject to the provisions of Section
        2.02(d) hereof, the Series 1999 Notes are subject to mandatory
        redemption at the direction of the Issuer, in whole or in part, on any
        Interest Payment Date, at a redemption price equal to the principal
        amount thereof plus interest accrued, if any, to the date of redemption
        thereof from moneys in the Senior Note Redemption Account of the Note
        Redemption Fund available therefor pursuant to the Indenture.

               (b)    Optional Redemptions and Optional Purchase.

                    (i) Optional Redemption of Series 1999 Notes. Subject to the
               provisions of Section 2.02(d) hereof, the Series 1999 Notes are
               subject to redemption at the option of the Issuer, from funds
               received by the Trustee constituting interest on Financed
               Eligible Loans remaining in the Revenue Fund after all other
               prior required payments have been made from the Revenue Fund, in
               whole or in part, on any Interest Payment Date, at a redemption
               price equal to the principal amount thereof being redeemed, plus
               interest accrued, if any, to the date of redemption.

                    (ii) Extraordinary Optional Redemption of Series 1999 Notes.
               Subject to the provisions of Section 2.02(d) hereof, the Series
               1999 Notes shall also be subject to extraordinary optional
               redemption, at the option of the Issuer, from any unallocated and
               available moneys in the Trust Estate, at a redemption price equal
               to the principal amount of the Series 1999 Notes being redeemed,
               plus accrued interest to the date of redemption, without premium
               in whole or in part on any Interest Payment Date, if the Issuer
               reasonably determines that it is unable to acquire Financed
               Eligible Loans, that the rate of return on Financed Eligible
               Loans has materially decreased, or that the costs of
               administering the Trust Estate have placed unreasonable burdens
               upon the ability of the Issuer to perform its obligations under
               the Indenture.

                    (iii) Optional Purchase of Series 1999 Notes. Subject to the
               provisions of Section 2.02(d) hereof, the Issuer may purchase or
               cause to be purchased all of the Series 1999 Notes on any
               Interest Payment Date on which the aggregate current principal
               balance of the Series 1999 Notes shall be less than or equal to
               10% of the initial aggregate principal balance of the Series 1999
               Notes on their Date of Issuance, at a purchase price equal to the
               aggregate current principal balance of such Series 1999 Notes,
               plus accrued interest on the Series 1999 Notes through the day
               preceding the Interest Payment Date on which the purchase occurs.
               The amount deposited pursuant to this subsection (iv) shall be
               paid to the Registered Owners on the related Interest Payment
               Date following the date of such deposit. All Series 1999 Notes
               which are purchased pursuant to this subsection (iv) shall be
               delivered by the Issuer upon such purchase to, and be canceled
               by, the Trustee and be disposed of in a manner satisfactory to
               the Trustee and the Issuer.

               (c) Notice of Redemption and Purchase. The Trustee shall cause
        notice of any redemption or purchase to be given by mailing a copy of
        the notice by first-class mail to the Registered Owner of any Series
        1999 Notes, and the Auction Agent, designated for redemption or purchase
        in whole or in part, at their address as the same shall last appear upon
        the registration books, in each case not less than 15 days prior to the
        redemption or purchase date; provided, however, that failure to give
        such notice, or any defect therein, shall not affect the validity of any
        proceedings for the redemption or purchase date of such Series 1999
        Notes for which no such failure or defect occurs.

               (d)    Partial Redemption.

                    (i) If less than all of the Series 1999 Notes are to be
               redeemed pursuant to Section 2.02(a) or 2.02(b) hereof, the
               subclass of Series 1999 Notes to be redeemed shall be redeemed as
               directed by an Issuer Order. If less than all of the Series 1999
               Notes of any Stated Maturity of any subclass of the Series 1999
               Notes are to be redeemed, the Series 1999 Notes of the same
               Stated Maturity to be redeemed shall be selected by lot in such
               manner as the Trustee shall determine. Notwithstanding the
               foregoing, the Series 1999 Notes may only be redeemed pursuant to
               the provisions of Section 5.06 of the Indenture.

                    (ii) In case a Series 1999 Note is of a denomination larger
               than an Authorized Denomination, a portion of such Note (in an
               Authorized Denomination) may be redeemed. Upon surrender of any
               Series 1999 Note for redemption in part only, the Issuer shall
               execute and the Trustee shall authenticate and deliver to the
               Registered Owner thereof, the cost of which shall be paid by the
               Issuer, a new Series 1999 Note or Series 1999 Notes of the same
               series, maturity and of authorized denominations, in an aggregate
               principal amount equal to the unredeemed portion of the Series
               1999 Note surrendered.

authentication certificate upon the Series 1999 Notes shall be substantially in
the form provided in Exhibit A hereof. No Series 1999 Note shall be secured
hereby or entitled to the benefit hereof, or shall be valid or obligatory for
any purpose, unless a certificate of authentication, substantially in such form,

evidence that such Bond has been authenticated and delivered hereunder. The
Trustee's certificate of authentication shall be deemed to have been duly

                                   ARTICLE II

                               TERMS AND ISSUANCE

        Section 2.01. Auction Rate Notes. During the Initial Period, the Auction
Rate Notes shall bear interest at the Initial Rate for such Subclass.
Thereafter, and except with respect to an Auction Period Adjustment, the Auction
Rate Notes shall bear interest at an Auction Note Interest Rate based on a
28-day Auction Period for the Auction Rate Notes, as determined pursuant to this
Section 2.01 and Section 2.02 hereof.

        For the Auction Rate Notes during the Initial Period and each Auction
Period thereafter, interest at the applicable Auction Rate Notes Interest Rate
shall accrue daily and shall be computed for the actual number of days elapsed
on the basis of a year consisting of 360 days.

        The Auction Note Interest Rate to be borne by the Auction Rate Notes
after such Initial Period for each Auction Period until an Auction Period
Adjustment, if any, shall be determined as described below. Each such Auction
Period after the Initial Period shall commence on and include the day following
the expiration of the immediately preceding Auction Period and terminate on and
include the (i) third Business Day of the following fourth week in the case of
the Class 1999A-13 Notes, (ii) third Business Day of the following fourth week
in the case of the Class 1999A-14 Notes, (iii) third Business Day of the
following fourth week in the case of the Class 1999A-15 Notes, and (iv) third
Business Day of the following fourth week in the case of the Class 1999A-16
Notes; provided, however, that in the case of the Auction Period that
immediately follows the Initial Period for the Auction Rate Notes, such Auction
Period shall commence on the Initial Rate Adjustment Date. The Auction Note
Interest Rate of the Auction Rate Notes for each Auction Period shall be the
Auction Rate in effect for such Auction Period as determined in accordance with
Section 2.02(a) hereof; provided that if, on any Interest Rate Determination
Date, an Auction is not held for any reason, then the Auction Note Interest Rate
on such Auction Rate Notes for the next succeeding Auction Period shall be the
applicable Maximum Auction Rate.

        Notwithstanding the foregoing:

               (a) if the ownership of an Auction Rate Note is no longer
        maintained in Book-entry Form, the Auction Note Interest Rate on the
        Auction Rate Notes for any Interest Period commencing after the delivery
        of certificates representing Auction Rate Notes pursuant to this
        Supplemental Indenture shall equal the applicable Maximum Auction Rate
        on the Business Day immediately preceding the first day of such
        subsequent Interest Period; or

               (b) if a Payment Default shall have occurred, the Auction Note
        Interest Rate on the Auction Rate Notes for the Interest Period
        commencing on or immediately after such Payment Default, and for each
        Interest Period thereafter, to and including the Interest Period, if
        any, during which, or commencing less than two Business Days after, such
        Payment Default is cured, shall equal the applicable Non-Payment Rate on
        the first day of each such Interest Period.

                                       A-8
<PAGE>

        In accordance with Section 2.02(a)(iii)(B) hereof, the Auction Agent
shall promptly give written notice to the Trustee and the Issuer of each Auction
Note Interest Rate (unless the Auction Note Interest Rate is the applicable
Non-Payment Rate) and the Maximum Auction Rate when such rate is not the Auction
Note Interest Rate, applicable to the Auction Rate Notes. The Trustee shall
notify the Registered Owners of Auction Rate Notes of the applicable Auction
Note Interest Rate applicable to such Auction Rate Notes for each Auction Period
not later than the third Business Day of such Auction Period.

        Notwithstanding any other provision of the Auction Rate Notes or this
Supplemental Indenture and except for the occurrence of a Payment Default,
interest payable on the Auction Rate Notes for an Auction Period shall never
exceed for such Auction Period the amount of interest payable at the applicable
Maximum Auction Rate in effect for such Auction Period.

        If the Auction Rate for the Auction Rate Notes is greater than the
applicable Maximum Auction Rate, then the Variable Rate applicable to such
Auction Rate Notes for that Interest Period will be the applicable Maximum
Auction Rate. If the Variable Rate applicable to such Auction Rate Notes for any
Interest Period is the applicable Maximum Auction Rate (without regard to the
last two clauses of the definition thereof), the Trustee shall determine the
Carry-over Amount, if any, with respect to such Auction Rate Notes for such
Interest Period. Such Carry-over Amount shall bear interest calculated at a rate
equal to One-Month LIBOR (as determined by the Auction Agent, provided the
Trustee has received notice of One-Month LIBOR from the Auction Agent, and if
the Trustee shall not have received such notice from the Auction Agent, then as
determined by the Trustee) from the Interest Payment Date for the Interest
Period with respect to which such Carry-over Amount was calculated, until paid.
Any payment in respect of Carry-over Amount shall be applied, first, to any
accrued interest payable thereon and, second, in reduction of such Carry-over
Amount. For purposes of this Appendix A, any reference to "principal" or
"interest" herein shall not include within the meaning of such words Carry-over
Amount or any interest accrued on any such Carry-over Amount. Such Carry-over
Amount shall be separately calculated for each Auction Rate Note by the Trustee
during such Interest Period in sufficient time for the Trustee to give notice to
each Registered Owner of such Carry-over Amount as required in the next
succeeding sentence. Not less than four days before the Interest Payment Date
for an Interest Period with respect to which such Carry-over Amount has been
calculated by the Trustee, the Trustee shall give written notice to each
Registered Owner of the Carry-over Amount applicable to each Registered Owner's
Auction Rate Note, which written notice may accompany the payment of interest by
check made to each such Registered Owner on such Interest Payment Date or
otherwise shall be mailed on such Interest Payment Date by first-class mail,
postage prepaid, to each such Registered Owner at such Registered Owner's
address as it appears on the registration records maintained by the Registrar.
Such notice shall state, in addition to such Carry-over Amount, that, unless and
until an Auction Rate Note has been redeemed (other than by optional
redemption), after which all accrued Carry-over Amounts (and all accrued
interest thereon) that remains unpaid shall be canceled and no Carry-over Amount
(and interest accrued thereon) shall be paid with respect to an Auction Rate
Note, (a) the Carry-over Amount (and interest accrued thereon calculated at a
rate equal to One-Month LIBOR) shall be paid by the Trustee on an Auction Rate
Note on the earliest of (i) the date of defeasance of the Auction Rate Notes or
(ii) the first occurring Interest Payment Date (or on the date of any such
optional redemption) if and to the extent that (A) the Eligible Carry-over
Make-Up Amount with respect to such subsequent Interest Period is greater than
zero, and (B) moneys are available pursuant to the terms of this Appendix A in
an amount sufficient to pay all or a portion of such Carry-over Amount (and
interest accrued thereon), and (b) interest shall accrue on the Carry-over
Amount at a rate equal to One-Month LIBOR until such Carry-over Amount is paid
in full or is cancelled.

                                       A-9
<PAGE>

        The Carry-over Amount (and interest accrued thereon) for Auction Rate
Notes shall be paid by the Trustee on Outstanding Auction Rate Notes on the
earliest of (a) the date of defeasance of any of the Auction Rate Notes or (b)
the first occurring Interest Payment Date if and to the extent that (i) the
Eligible Carry-over Make-Up Amount with respect to such Interest Period is
greater than zero, and (ii) on such Interest Payment Date there are sufficient
moneys in the Senior Interest Account of the Interest Fund to pay all interest
due on the Auction Rate Notes on such Interest Payment Date. Any Carry-over
Amount (and any interest accrued thereon) on any Auction Rate Note which is due
and payable on an Interest Payment Date, which Auction Rate Note is to be
redeemed (other than by optional redemption) on said Interest Payment Date,
shall be paid to the Registered Owner thereof on said Interest Payment Date to
the extent that moneys are available therefor in accordance with the provisions
of this Appendix A; provided, however, that any Carry-over Amount (and any
interest accrued thereon) which is not yet due and payable on said Interest
Payment Date shall be cancelled with respect to said Auction Rate Note that is
to be redeemed (other than by optional redemption) on said Interest Payment Date
and shall not be paid on any succeeding Interest Payment Date. To the extent
that any portion of the Carry-over Amount (and any interest accrued thereon)
remains unpaid after payment of a portion thereof, such unpaid portion shall be
paid in whole or in part as required hereunder until fully paid by the Trustee
on the earliest of (a) the date of defeasance of any of the Auction Rate Notes
or (b) the next occurring Interest Payment Date or Dates, as necessary, if and
to the extent that the conditions in the second preceding sentence are
satisfied. On any Interest Payment Date on which the Trustee pays only a portion
of the Carry-over Amount (and any interest accrued thereon) on Auction Rate
Notes, the Trustee shall give written notice in the manner set forth in the
immediately preceding paragraph to the Registered Owner of such Auction Rate
Note receiving such partial payment of the Carry-over Amount remaining unpaid on
such Auction Rate Note.

        The Interest Payment Date or other date on which such Carry-over Amount
(or any interest accrued thereon) for Auction Rate Notes shall be paid shall be
determined by the Trustee in accordance with the provisions of the immediately
preceding paragraph, and the Trustee shall make payment of the Carry-over Amount
(and any interest accrued thereon) in the same manner as, and from the same
Account from which, it pays interest on the Auction Rate Notes on an Interest
Payment Date. Any payment of Carry-over Amounts (and interest accrued thereon)
shall reduce the amount of Eligible Carry-Over Make-Up Amount.

        In the event that the Auction Agent no longer determines, or fails to
determine, when required, the Auction Note Interest Rate with respect to Auction
Rate Notes, or, if for any reason such manner of determination shall be held to
be invalid or unenforceable, the Auction Note Interest Rate for the next
succeeding Interest Period, which Interest Period shall be an Auction Period,
for Auction Rate Notes shall be the applicable Maximum Auction Rate as
determined by the Auction Agent for such next succeeding Auction Period, and if
the Auction Agent shall fail or refuse to determine the Maximum Auction Rate,
the Maximum Auction Rate shall be determined by the securities dealer appointed
by the Issuer capable of making such a determination in accordance with the
provisions hereof and written notice of such determination shall be given by
such securities dealer to the Trustee.

        Section 2.02.  Auction Rate Note Interest Rate.

               (a) Determining the Auction Rate Note Interest Rate. By
        purchasing Auction Rate Notes, whether in an Auction or otherwise, each
        purchaser of the Auction Rate Notes, or its Broker-Dealer, must agree
        and shall be deemed by such purchase to have agreed (x) to participate
        in Auctions on the terms described herein, (y) to have its beneficial
        ownership of the Auction Rate Notes maintained at all times in
        Book-entry Form for the account of its Participant, which in turn will
        maintain records of such beneficial ownership and (z) to authorize such
        Participant to disclose to the Auction Agent such information with
        respect to such beneficial ownership as the Auction Agent may request.

               So long as the ownership of Auction Rate Notes is maintained in
        Book-entry Form by the Securities Depository, an Existing Owner may
        sell, transfer or otherwise dispose of Auction Rate Notes only pursuant
        to a Bid or Sell Order placed in an Auction or otherwise sell, transfer
        or dispose of Auction Rate Notes through a Broker-Dealer, provided that,
        in the case of all transfers other than pursuant to Auctions, such
        Existing Owner, its Broker-Dealer or its Participant advises the Auction
        Agent of such transfer. Auctions shall be conducted on each Auction
        Date, if there is an Auction Agent on such Auction Date, in the
        following manner:

                      (i)    (A)    Prior to the Submission Deadline on each
                             Auction Date;

                                    (1) each Existing Owner of Auction Rate
                             Notes may submit to a Broker-Dealer by telephone or
                             otherwise any information as to:

                                            a. the principal amount of
                                    Outstanding Auction Rate Notes, if any,
                                    owned by such Existing Owner which such
                                    Existing Owner desires to continue to own
                                    without regard to the Auction Note Interest
                                    Rate for the next succeeding Auction Period;

                                            b. the principal amount of
                                    Outstanding Auction Rate Notes, if any,
                                    which such Existing Owner offers to sell if
                                    the Auction Note Interest Rate for the next
                                    succeeding Auction Period shall be less than
                                    the rate per annum specified by such
                                    Existing Owner; and/or

                                            c. the principal amount of
                                    Outstanding Auction Rate Notes, if any,
                                    owned by such Existing Owner which such
                                    Existing Owner offers to sell without regard
                                    to the Auction Note Interest Rate for the
                                    next succeeding Auction Period;

                                    and

                                    (2) one or more Broker-Dealers may contact
                             Potential Owners to determine the principal amount
                             of Auction Rate Notes which each Potential Owner
                             offers to purchase, if the Auction Note Interest
                             Rate for the next succeeding Auction Period shall
                             not be less than the rate per annum specified by
                             such Potential Owner.

                                    (1) the name of the Bidder placing such
                             Order;

                                    (2) the aggregate principal amount of
                             Auction Rate Notes that are the subject of such
                             Order;

                                    (3) to the extent that such Bidder is an
                             Existing Owner:

                                            a. the principal amount  of  Auction
                                    Rate Notes, if any, subject to any Hold
                                    Order  placed by such  Existing Owner;

                                            b. the principal amount of Auction

                                    specified in such Bid; and

                                            c. the principal amount  of  Auction
                                    Rate Notes, if any, subject to any Sell

                             and

                                    (4) to the extent such Bidder is a Potential

                      than three figures to the right of the decimal point, the

                      submitted to the Auction Agent prior to the Submission

                      covering the principal amount of Outstanding Auction Rate
                      Notes owned by such Existing Owner and not subject to an
                      Order submitted to the Auction Agent.

                             (D) Neither the Issuer, the Trustee nor the Auction
                      Agent shall be responsible for any failure of a
                      Broker-Dealer to submit an Order to the Auction Agent on
                      behalf of any Existing Owner or Potential Owner.

                             (E) If any Existing Owner submits through a
                      Broker-Dealer to the Auction Agent one or more Orders
                      covering in the aggregate more than the principal amount
                      of Outstanding Auction Rate Notes owned by such Existing
                      Owner, such Orders shall be considered valid as follows
                      and in the following order of priority:

                                    (1) All Hold Orders shall be considered
                             valid, but only up to the aggregate principal
                             amount of Outstanding Auction Rate Notes owned by
                             such Existing Owner, and if the aggregate principal
                             amount of Auction Rate Notes subject to such Hold
                             Orders exceeds the aggregate principal amount of
                             Auction Rate Notes owned by such Existing Owner,
                             the aggregate principal amount of Auction Rate
                             Notes subject to each such Hold Order shall be
                             reduced pro rata so that the aggregate principal
                             amount of Auction Rate Notes subject to such Hold
                             Order equals the aggregate principal amount of
                             Outstanding Auction Rate Notes owned by such
                             Existing Owner.

                                    (2) a. Any Bid shall be considered valid up
                                    to an amount equal to the excess of the
                                    principal amount of Outstanding Auction Rate
                                    Notes owned by such Existing Owner over the
                                    aggregate principal amount of Auction Rate
                                    Notes subject to any Hold Order referred to
                                    in clause (A) of this paragraph (v);

                                            b. subject to subclause (1) of this
                                    clause (B), if more than one Bid with the
                                    same rate is submitted on behalf of such
                                    Existing Owner and the aggregate principal
                                    amount of Outstanding Auction Rate Notes
                                    subject to such Bids is greater than such
                                    excess, such Bids shall be considered valid
                                    up to an amount equal to such excess;

                                            c. subject to subclauses (1) and (2)
                                    of this clause (B), if more than one Bid
                                    with different rates are submitted on behalf
                                    of such Existing Owner, such Bids shall be
                                    considered valid first in the ascending
                                    order of their respective rates until the
                                    highest rate is reached at which such excess
                                    exists and then at such rate up to the
                                    amount of such excess; and

                                            d. in any such event, the amount of
                                    Outstanding Auction Rate Notes, if any,
                                    subject to Bids not valid under this clause
                                    (B) shall be treated as the subject of a Bid
                                    by a Potential Owner at the rate therein
                                    specified; and

                                    (3) All Sell Orders shall be considered
                             valid up to an amount equal to the excess of the
                             principal amount of Outstanding Auction Rate Notes
                             owned by such Existing Owner over the aggregate
                             principal amount of Auction Rate Notes subject to
                             Hold Orders referred to in clause (1) of this
                             paragraph (v) and valid Bids referred to in clause
                             (2) of this paragraph (E).

                             (F) If more than one Bid for Auction Rate Notes is
                      submitted on behalf of any Potential Owner, each Bid
                      submitted shall be a separate Bid with the rate and
                      principal amount therein specified.

                             (G) An Existing Owner that offers to purchase
                      additional Auction Rate Notes is, for purposes of such
                      offer, treated as a Potential Owner.

                             (H) Any Bid or Sell Order submitted by an Existing
                      Owner covering an aggregate principal amount of Auction
                      Rate Notes not equal to an Authorized Denomination shall
                      be rejected and shall be deemed a Hold Order. Any Bid
                      submitted by a Potential Owner covering an aggregate
                      principal amount of Auction Rate Notes not equal to an
                      Authorized Denomination shall be rejected.

                             (I) Any Bid specifying a rate higher than the
                      applicable Maximum Auction Rate will (1) be treated as a
                      Sell Order if submitted by an Existing Owner and (2) not
                      be accepted if submitted by a Potential Owner.

                             (J) Any Order submitted in an Auction by a
                      Broker-Dealer to the Auction Agent prior to the Submission
                      Deadline on any Auction Date shall be irrevocable.

                      (iii) (A) Not earlier than the Submission Deadline on each
                      Auction Date, the Auction Agent shall assemble all valid
                      Orders submitted or deemed submitted to it by the
                      Broker-Dealers (each such Order as submitted or deemed
                      submitted by a Broker-Dealer being herein referred to
                      individually as a "Submitted Hold Order," a "Submitted
                      Bid" or a "Submitted Sell Order," as the case may be, or
                      as a "Submitted Order," and collectively as "Submitted
                      Hold Orders," "Submitted Bids" or "Submitted Sell Orders,"
                      as the case may be, or as "Submitted Orders") and shall
                      determine:

                                    (1) the excess of the total principal amount
                             of Outstanding Auction Rate Notes over the sum of
                             the aggregate principal amount of Outstanding
                             Auction Rate Notes subject to Submitted Hold Orders
                             (such excess being herein referred to as the
                             "Available Auction Rate Notes"), and

                                    (2) from the Submitted Orders whether:

                                            a. the aggregate principal amount of
                                    Outstanding Auction Rate Notes subject to
                                    Submitted Bids by Potential Owners
                                    specifying one or more rates equal to or
                                    lower than the applicable Maximum Auction
                                    Rate;

                       exceeds or is equal to the sum of:

                                            b. the aggregate principal amount of
                                    Outstanding Auction Rate Notes subject to
                                    Submitted Bids by Existing Owners specifying
                                    one or more rates higher than the applicable
                                    Maximum Auction Rate; and

                                            c. the aggregate principal amount of
                                    Outstanding  Auction Rate Notes subject to
                                    Submitted  Sell Orders;

                             (in the event such excess or such equality exists,
                             other than because all of the Outstanding Auction
                             Rate Notes are subject to Submitted Hold Orders,
                             such Submitted Bids described in subclause a. above
                             shall be referred to collectively as "Sufficient
                             Bids"); and

                                    (3) if Sufficient Bids exist, the Bid
                             Auction Rate, which shall be the lowest rate
                             specified in such Submitted Bids such that if:

                                            a. (x) each Submitted Bid from
                                    Existing Owners specifying such lowest rate
                                    and (y) all other Submitted Bids from
                                    Existing Owners specifying lower rates were
                                    rejected, thus entitling such Existing
                                    Owners to continue to own the principal
                                    amount of Auction Rate Notes subject to such
                                    Submitted Bids; and

                                            b. (x) each such Submitted Bid from
                                    Potential Owners specifying such lowest rate
                                    and (y) all other Submitted Bids from
                                    Potential Owners specifying lower rates were
                                    accepted;

                             the result would be that such Existing Owners
                             described in subclause a. above would continue to
                             own an aggregate principal amount of Outstanding
                             Auction Rate Notes which, when added to the
                             aggregate principal amount of Outstanding Auction
                             Rate Notes to be purchased by such Potential Owners
                             described in subclause b. above, would equal not
                             less than the Available Auction Rate Notes.

                             (B) Promptly after the Auction Agent has made the
                      determinations pursuant to Section 2.02(a)(iii)(A) hereof,
                      the Auction Agent shall advise the Trustee, the
                      Broker-Dealers and the Issuer of the Maximum Auction Rate
                      and the All Hold Rate and the components thereof on the
                      Auction Date and, based on such determinations, the
                      Auction Rate for the next succeeding Interest Period as
                      follows:

                                    (1) if Sufficient Bids exist, that the
                             Auction Rate for the next succeeding Interest
                             Period shall be equal to the Bid Auction Rate so
                             determined;

                                    (2) if Sufficient Bids do not exist (other
                             than because all of the Outstanding Auction Rate
                             Notes are subject to Submitted Hold Orders), that
                             the Auction Rate for the next succeeding Interest
                             Period shall be equal to the applicable Maximum
                             Auction Rate; or

                                    (3) if all Outstanding Auction Rate Notes
                             are subject to Submitted Hold Orders, that the
                             Auction Rate for the next succeeding Interest
                             Period shall be equal to the applicable All Hold
                             Rate.

                             (C) Promptly after the Auction Agent has determined
                      the Auction Rate, the Auction Agent shall determine and
                      advise the Trustee of the Auction Note Interest Rate,
                      which rate shall be the Auction Rate; provided, however,
                      that in no event shall the Auction Note Interest Rate
                      exceed the applicable Maximum Auction Rate.

                      (iv) Existing Owners shall continue to own the principal
               amount of Auction Rate Notes that are subject to Submitted Hold
               Orders. If Sufficient Bids have been received by the Auction
               Agent, the Bid Auction Rate will be the Auction Note Interest
               Rate, and Submitted Bids and Submitted Sell Orders will be
               accepted or rejected and the Auction Agent will take such other
               action as described below in subparagraph (A).

                      If the Auction Rate is greater than the applicable Maximum
               Auction Rate, the Auction Note Interest Rate shall be equal to
               the applicable Maximum Auction Rate. If the Auction Agent has not
               received Sufficient Bids (other than because all of the
               Outstanding Auction Rate Notes are subject to Submitted Hold
               Orders), the Auction Note Interest Rate will be the applicable
               Maximum Auction Rate. In any of the cases described above,
               Submitted Orders will be accepted or rejected and the Auction
               Agent will take such other action as described below in
               subparagraph (B).

                             (A) If Sufficient Bids have been made and if the
                      applicable Maximum Auction Rate does not apply (in which
                      case the Auction Note Interest Rate shall be the Bid
                      Auction Rate), all Submitted Sell Orders shall be accepted
                      and, subject to the provisions of clauses (4) and (5) of
                      this Section 2.02(a)(iv), Submitted Bids shall be accepted
                      or rejected as follows in the following order of priority,
                      and all other Submitted Bids shall be rejected:

                                    (1) Existing Owners' Submitted Bids
                             specifying any rate that is higher than the Auction
                             Note Interest Rate shall be accepted, thus
                             requiring each such Existing Owner to sell the
                             aggregate principal amount of Auction Rate Notes
                             subject to such Submitted Bids;

                             specifying any rate that is lower than the Auction
                             Note Interest Rate shall be rejected, thus
                             entitling each such Existing Owner to continue to
                             own the aggregate principal amount of Auction Rate
                             Notes subject to such Submitted Bids;

                                    (3) Potential Owners' Submitted Bids
                             specifying any rate that is lower than the Auction
                             Note Interest Rate shall be accepted;

                                    (4) Each Existing Owners' Submitted Bid
                             specifying a rate that is equal to the Auction Note
                             Interest Rate shall be rejected, thus entitling
                             such Existing Owner to continue to own the
                             aggregate principal amount of Auction Rate Notes
                             subject to such Submitted Bid, unless the aggregate
                             principal amount of Outstanding Auction Rate Notes
                             subject to all such Submitted Bids shall be greater
                             than the principal amount of Auction Rate Notes
                             (the "remaining principal amount") equal to the
                             excess of the Available Auction Rate Notes over the
                             aggregate principal amount of Auction Rate Notes
                             subject to Submitted Bids described in clauses (2)
                             and (3) of this Section 2.02(a)(iv)(D)(1), in which
                             event such Submitted Bid of such Existing Owner
                             shall be rejected in part, and such Existing Owner
                             shall be entitled to continue to own the principal
                             amount of Auction Rate Notes subject to such
                             Submitted Bid, but only in an amount equal to the
                             aggregate principal amount of Auction Rate Notes
                             obtained by multiplying the remaining principal
                             amount by a fraction, the numerator of which shall
                             be the principal amount of Outstanding Auction Rate
                             Notes owned by such Existing Owner subject to such
                             Submitted Bid and the denominator of which shall be
                             the sum of the principal amount of Outstanding
                             Auction Rate Notes subject to such Submitted Bids
                             made by all such Existing Owners that specified a
                             rate equal to the Auction Note Interest Rate,
                             subject to the provisions of Section 2.02(a)(iv)(D)
                             hereof; and

                                    (5) Each Potential Owner's Submitted Bid
                             specifying a rate that is equal to the Auction Note
                             Interest Rate shall be accepted, but only in an
                             amount equal to the principal amount of Auction
                             Rate Notes obtained by multiplying the excess of
                             the aggregate principal amount of Available Auction
                             Rate Notes over the aggregate principal amount of
                             Auction Rate Notes subject to Submitted Bids
                             described in clauses (2), (3) and (4) of this
                             Section 2.02(a)(iv)(A) by a fraction the numerator
                             of which shall be the aggregate principal amount of
                             Outstanding Auction Rate Notes subject to such
                             Submitted Bid and the denominator of which shall be
                             the sum of the principal amount of Outstanding
                             Auction Rate Notes subject to Submitted Bids made
                             by all such Potential Owners that specified a rate
                             equal to the Auction Note Interest Rate, subject to
                             the provisions of Section 2.02(a)(iv)(D) hereof.

                             (B) If Sufficient Bids have not been made (other
                      than because all of the Outstanding Auction Rate Notes are
                      subject to submitted Hold Orders), or if the applicable
                      Maximum Auction Rate applies, subject to the provisions of
                      Section 2.02(a)(iv)(D) hereof, Submitted Orders shall be
                      accepted or rejected as follows in the following order of
                      priority and all other Submitted Bids shall be rejected:

                                    (1) Existing Owners' Submitted Bids
                             specifying any rate that is equal to or lower than
                             the Auction Note Interest Rate shall be rejected,
                             thus entitling such Existing Owners to continue to
                             own the aggregate principal amount of Auction Rate
                             Notes subject to such Submitted Bids;

                                    (2) Potential Owners' Submitted Bids
                             specifying (x) any rate that is equal to or lower
                             than the Auction Note Interest Rate shall be
                             accepted and (y) any rate that is higher than the
                             Auction Note Interest Rate shall be rejected; and

                                    (3) each Existing Owner's Submitted Bid
                             specifying any rate that is higher than the Auction
                             Note Interest Rate and the Submitted Sell Order of
                             each Existing Owner shall be accepted, thus
                             entitling each Existing Owner that submitted any
                             such Submitted Bid or Submitted Sell Order to sell
                             the Auction Rate Notes subject to such Submitted
                             Bid or Submitted Sell Order, but in both cases only
                             in an amount equal to the aggregate principal
                             amount of Auction Rate Notes obtained by
                             multiplying the aggregate principal amount of
                             Auction Rate Notes subject to Submitted Bids
                             described in clause (2)(x) of this Section
                             2.02(a)(iv)(B) by a fraction the numerator of which
                             shall be the aggregate principal amount of
                             Outstanding Auction Rate Notes owned by such
                             Existing Owner subject to such submitted Bid or
                             Submitted Sell Order and the denominator of which
                             shall be the aggregate principal amount of
                             Outstanding Auction Rate Notes subject to all such
                             Submitted Bids and Submitted Sell Orders.

                             (C) If all Auction Rate Notes are subject to
                      Submitted Hold Orders, all Submitted Bids shall be
                      rejected.

                             (D) If, as a result of the procedures described in
                      paragraph (A) or (B) of this Section 2.02(a)(iv), any
                      Existing Owner would be entitled or required to sell, or
                      any Potential Owner would be entitled or required to
                      purchase, a principal amount of Auction Rate Notes that is
                      not equal to an Authorized Denomination, the Auction Agent
                      shall, in such manner as in its sole discretion it shall
                      determine, round up or down the principal amount of
                      Auction Rate Notes to be purchased or sold by any Existing
                      Owner or Potential Owner so that the principal amount of
                      Auction Rate Notes purchased or sold by each Existing
                      Owner or Potential Owner shall be equal to an Authorized
                      Denomination.

                             (E) If, as a result of the procedures described in
                      paragraph (B) of this Section 2.02(a)(iv), any Potential
                      Owner would be entitled or required to purchase less than
                      an Authorized Denomination of Auction Rate Notes, the
                      Auction Agent shall, in such manner as in its sole
                      discretion it shall determine, allocate Auction Rate Notes
                      for purchase among Potential Owners so that only Auction
                      Rate Notes in Authorized Denominations are purchased by
                      any Potential Owner, even if such allocation results in
                      one or more of such Potential Owners not purchasing any
                      Auction Rate Notes.

                      (v) Based on the result of each Auction, the Auction Agent
               shall determine the aggregate principal amount of Auction Rate
               Notes to be purchased and the aggregate principal amount of
               Auction Rate Notes to be sold by Potential Owners and Existing
               Owners on whose behalf each Broker-Dealer submitted Bids or Sell
               Orders and, with respect to each Broker-Dealer, to the extent
               that such aggregate principal amount of Auction Rate Notes to be
               sold differs from such aggregate principal amount of Auction Rate
               Notes to be purchased, determine to which other Broker-Dealer or
               Broker-Dealers acting for one or more purchasers such
               Broker-Dealer shall deliver, or from which other Broker-Dealer or
               Broker-Dealers acting for one or more sellers such Broker-Dealer
               shall receive, as the case may be, Auction Rate Notes.

                      (vi) Any calculation by the Auction Agent or the Trustee,
               as applicable, of the Auction Note Interest Rate, the Maximum
               Auction Rate, the All Hold Rate and the Non-Payment Rate shall,
               in the absence of manifest error, be binding on all other
               parties.

                      (vii) Notwithstanding anything in this Appendix A to the
               contrary, (A) no Auction for the Auction Rate Notes for an
               Auction Period of less than 180 days will be held on any Auction
               Date hereunder on which there are insufficient moneys in the
               Senior Interest Account of the Interest Fund and the Senior
               Redemption Account of the Note Redemption Fund to pay, or
               otherwise held by the Trustee under the Indenture and available
               to pay, the principal of and interest due on the Auction Rate
               Notes on the Interest Payment Date immediately following such
               Auction Date, and (B) no Auction will be held on any Auction Date
               hereunder during the continuance of a Payment Default. The
               Trustee shall promptly notify the Auction Agent of any such
               occurrence.

               (b)  Application of Interest Payments for the Auction Rate Notes.

                      (i) The Trustee shall determine not later than 2:00 p.m.,
               eastern time, on the Business Day next succeeding an Interest
               Payment Date, whether a Payment Default has occurred. If a
               Payment Default has occurred, the Trustee shall, not later than
               2:15 p.m., eastern time, on such Business Day, send a notice
               thereof in substantially the form of Exhibit C attached hereto to
               the Auction Agent by telecopy or similar means and, if such
               Payment Default is cured, the Trustee shall immediately send a
               notice in substantially the form of Exhibit D attached hereto to
               the Auction Agent by telecopy or similar means.

                      (ii) Not later than 2:00 p.m., eastern time, on each
               anniversary of the Closing Date, the Trustee shall pay to the
               Auction Agent, in immediately available funds out of amounts in
               the Revenue Fund, an amount equal to the Auction Agent Fee as set
               forth in the Auction Agent Agreement. Not later than 2:00 p.m.,
               eastern time, on each Auction Date, the Trustee shall pay to the
               Auction Agent, in immediately available funds out of amounts in
               the Revenue Fund, an amount equal to the Broker-Dealer Fee as
               calculated in the Auction Agent Agreement. The Trustee shall,
               from time to time at the request of the Auction Agent and at the
               direction of an Authorized Officer, reimburse the Auction Agent
               for its reasonable expenses as provided in the Auction Agent
               Agreement, such expenses to be paid out of amounts in the Revenue
               Fund.

               (c) Calculation of Maximum Auction Rate, All Hold Rate and
        Non-Payment Rate. The Auction Agent shall calculate the applicable
        Maximum Auction Rate and All Hold Rate, as the case may be, on each
        Auction Date and shall notify the Trustee and the Broker-Dealers of the
        applicable Maximum Auction Rate and All Hold Rate, as the case may be,
        as provided in the Auction Agent Agreement; provided, that if the
        ownership of the Auction Rate Notes is no longer maintained in
        Book-entry Form, or if a Payment Default has occurred, then the Trustee
        shall determine the applicable Maximum Auction Rate, All Hold Rate and
        Non-Payment Rate for each such Interest Period. The Market Agent shall
        calculate the Index (if the Index is other than the PSA Municipal Swap
        Index) on each Interest Rate Determination Date and shall notify the
        Trustee and the Auction Agent of the Index prior to 9:30 a.m., eastern
        time, on each Interest Rate Determination Date. If the ownership of the
        Auction Rate Notes is no longer maintained in Book-entry Form by the
        Securities Depository, the Trustee shall calculate the applicable
        Maximum Auction Rate on the Business Day immediately preceding the first
        day of each Interest Period after the delivery of certificates
        representing the Auction Rate Notes pursuant to the Indenture. If a
        Payment Default shall have occurred, the Trustee shall calculate the
        Non-Payment Rate on the Interest Rate Determination Date for (i) each
        Interest Period commencing after the occurrence and during the
        continuance of such Payment Default and (ii) any Interest Period
        commencing less than two Business Days after the cure of any Payment
        Default. The determination by the Trustee or the Auction Agent, as the
        case may be, of the applicable Maximum Auction Rate, All Hold Rate and
        Non-Payment Rate shall (in the absence of manifest error) be final and
        binding upon all parties. If calculated or determined by the Auction
        Agent, the Auction Agent shall promptly advise the Trustee of the
        applicable Maximum Auction Rate and All Hold Rate. The determination by
        the Market Agent of the Index shall (in the absence of manifest error)
        be final and binding upon all parties.

               If the Federal Reserve Bank of New York does not make available
        its 30-day commercial paper rate for purposes of determining the "AA"
        Composite Commercial Paper Rate, the Auction Agent shall notify the
        Trustee of such fact and the Trustee shall thereupon request that an

        Dealers (in addition to PaineWebber Incorporated) to provide commercial
        paper quotes for purposes of determining the "AA" Composite Commercial

        Dealers, PaineWebber Incorporated and any other Commercial Paper Dealer
        appointed and serving as such shall provide the required quotations, and
        such quotations shall be used for purposes of this Appendix A.
        PaineWebber Incorporated is hereby appointed as a Commercial Paper
        Dealer to provide commercial paper quotes for purposes of determining
        the "AA" Composite Commercial Paper Rate as provided above.

               (d)    Notification of Rates, Amounts and Payment Dates.

                      (i) By 12:00 noon, eastern time, on the Business Day
               following each Regular Record Date, the Trustee shall determine
               the aggregate amounts of interest distributable on the next
               succeeding Interest Payment Date to the beneficial owners of
               Auction Rate Notes.

                      (ii) At least four days prior to any Interest Payment
               Date, the Trustee shall:

                             (A) confirm with the Auction Agent, so long as no
                      Payment Default has occurred and is continuing and the
                      ownership of the Auction Rate Notes is maintained in
                      Book-entry Form by the Securities Depository, (1) the date
                      of such next Interest Payment Date and (2) the amount
                      payable to the Auction Agent on the Auction Date pursuant
                      to Section 2.02(b)(ii) hereof;

                             (B) pursuant to Section 2.01 hereof, advise the
                      Registered Owners of a Subclass of Auction Rate Notes of
                      any Carry-over Amount accruing on such Auction Rate Notes;
                      and

                             (C) advise the Securities Depository, so long as
                      the ownership of the Auction Rate Notes is maintained in
                      Book-entry Form by the Securities Depository, upon
                      request, of the aggregate amount of interest distributable
                      on such next Interest Payment Date to the beneficial
                      owners of each Subclass of the Auction Rate Notes.

               If any day scheduled to be an Interest Payment Date shall be
        changed after the Trustee shall have given the notice or confirmation
        referred to in clause (i) of the preceding sentence, the Trustee shall,
        not later than 11:15 a.m., eastern time, on the Business Day next
        preceding the earlier of the new Interest Payment Date or the old
        Interest Payment Date, by such means as the Trustee deems practicable,
        give notice of such change to the Auction Agent, so long as no Payment
        Default has occurred and is continuing and the ownership of the Auction
        Rate Notes is maintained in Book-entry Form by the Securities
        Depository.

               (e)    Auction Agent.

                      (i) Bankers Trust Company is hereby appointed as Initial
               Auction Agent to serve as agent for the Issuer in connection with
               Auctions. The Trustee and the Issuer will, and the Trustee is
               hereby directed to, enter into the Initial Auction Agent
               Agreement with Bankers Trust Company, as the Initial Auction
               Agent. Any Substitute Auction Agent shall be (A) a bank, national
               banking association or trust company duly organized under the
               laws of the United States of America or any state or territory
               thereof having its principal place of business in the Borough of
               Manhattan, New York, or such other location as approved by the
               Trustee in writing and having a combined capital stock or surplus
               of at least $50,000,000, or (B) a member of the National
               Association of Securities Dealers, Inc., having a capitalization
               of at least $50,000,000, and, in either case, authorized by law
               to perform all the duties imposed upon it hereunder and under the
               Auction Agent Agreement. The Auction Agent may at any time resign
               and be discharged of the duties and obligations created by this
               Appendix A by giving at least 90 days' notice to the Trustee, the
               Market Agent and the Issuer. The Auction Agent may be removed at
               any time by the Trustee upon the written direction of an
               Authorized Officer or the Registered Owners of 51% of the
               aggregate principal amount of the Auction Rate Notes then
               Outstanding, and if by such Registered Owners, by an instrument
               signed by such Registered Owners or their attorneys and filed
               with the Auction Agent, the Issuer and the Trustee upon at least
               90 days' written notice. Neither resignation nor removal of the
               Auction Agent pursuant to the preceding two sentences shall be
               effective until and unless a Substitute Auction Agent has been
               appointed and has accepted such appointment. If required by the
               Issuer, a Substitute Auction Agent Agreement shall be entered
               into with a Substitute Auction Agent. Notwithstanding the
               foregoing, the Auction Agent may terminate the Auction Agent
               Agreement if, within 25 days after notifying the Trustee, the
               Market Agent and the Issuer in writing that it has not received
               payment of any Auction Agent Fee due it in accordance with the
               terms of the Auction Agent Agreement, the Auction Agent does not
               receive such payment.

                      (ii) If the Auction Agent shall resign or be removed or be
               dissolved, or if the property or affairs of the Auction Agent
               shall be taken under the control of any state or federal court or
               administrative body because of bankruptcy or insolvency, or for
               any other reason, the Trustee at the direction of an Authorized
               Officer, shall use its best efforts to appoint a Substitute
               Auction Agent.

                      (iii) The Auction Agent is acting as agent for the Issuer
               in connection with Auctions. In the absence of bad faith,
               negligent failure to act or negligence on its part, the Auction
               Agent shall not be liable for any action taken, suffered or
               omitted or any error of judgment made by it in the performance of
               its duties under the Auction Agent Agreement and shall not be
               liable for any error of judgment made in good faith unless the
               Auction Agent shall have been negligent in ascertaining (or
               failing to ascertain) the pertinent facts.

               (f)    Broker-Dealers.

                      (i) The Auction Agent will enter into a Broker-Dealer
               Agreement with PaineWebber Incorporated, as the initial
               Broker-Dealer. An Authorized Officer may, from time to time,
               approve one or more additional persons to serve as Broker-Dealers
               under Broker-Dealer Agreements and shall be responsible for
               providing such Broker-Dealer Agreements to the Trustee and the
               Auction Agent.

                      (ii) Any Broker-Dealer may be removed at any time, at the
               request of an Authorized Officer, but there shall, at all times,
               be at least one Broker-Dealer appointed and acting as such.

               (g) Changes in Auction Period or Periods and Certain Percentages.

                      (i) While any of the Auction Rate Notes are Outstanding,
               the Issuer may, from time to time, change the length of one or
               more Auction Periods (an "Auction Period Adjustment"), in order
               to conform with then current market practice with respect to
               similar securities or to accommodate economic and financial
               factors that may affect or be relevant to the length of the
               Auction Period and the interest rate borne by the Auction Rate
               Notes. The Issuer shall not initiate an Auction Period Adjustment
               unless it shall have received the written consent of the Market
               Agent, which consent shall not be unreasonably withheld, not
               later than nine days prior to the Auction Date for such Auction
               Period. The Issuer shall initiate the Auction Period Adjustment
               by giving written notice by Issuer Order to the Trustee, the
               Auction Agent, the Market Agent, each Rating Agency and the
               Securities Depository in substantially the form of, or containing
               substantially the information contained in, Exhibit E attached
               hereto at least 10 days prior to the Auction Date for such
               Auction Period.

                      (ii) Any such adjusted Auction Period shall not be less
               than 7 days nor more than 366 days.

                      (iii) An Auction Period Adjustment shall take effect only
               if (A) the Trustee and the Auction Agent receive, by 11:00 a.m.,
               eastern time, on the Business Day before the Auction Date for the
               first such Auction Period, an Issuer Certificate in substantially
               the form attached as, or containing substantially the same
               information contained in, Exhibit F attached hereto, authorizing
               the Auction Period Adjustment specified in such certificate along
               with a copy of the written consent of the Market Agent and, (B)
               Sufficient Bids exist as of the Auction on the Auction Date for
               such first Auction Period. If the condition referred to in (A)
               above is not met, the applicable Auction Note Interest Rate for
               the next Auction Period shall be determined pursuant to the above
               provisions of this Section 2.02 and the Auction Period shall be
               the Auction Period determined without reference to the proposed
               change. If the condition referred to in (A) is met but the
               condition referred in (B) above is not met, the applicable
               Auction Note Interest Rate for the next Auction Period shall be
               the applicable Maximum Auction Rate and the Auction Period shall
               be the Auction Period determined without reference to the
               proposed change.

<PAGE>

                      In connection with any Auction Period Adjustment, the
               Auction Agent shall provide such further notice to such parties
               as is specified in Section 2.03 of the Auction Agent Agreement.

               (h) Changes in the Auction Date. The Market Agent, with the
        written consent of an Authorized Officer and, if applicable, upon
        receipt of the opinion of Note Counsel as required below, may specify an
        earlier Auction Date (but in no event more than five Business Days
        earlier) than the Auction Date that would otherwise be determined in
        accordance with the definition of "Auction Date" in Section 1.01 of this
        Appendix A with respect to one or more specified Auction Periods in
        order to conform with then current market practice with respect to
        similar securities or to accommodate economic and financial factors that
        may affect or be relevant to the day of the week constituting an Auction
        Date and the interest rate borne on the Auction Rate Notes. The Market
        Agent shall deliver a written request for consent to such change in the
        length of the Auction Date to the Issuer at least 14 days prior to the
        effective date of such change. If the Issuer shall have delivered such
        written consent to the Market Agent, the Market Agent shall provide
        notice of its determination to specify an earlier Auction Date for one
        or more Auction Periods by means of a written notice delivered at least
        10 days prior to the proposed changed Auction Date to the Trustee, the
        Auction Agent, the Issuer, each Rating Agency and the Securities
        Depository. Such notice shall be substantially in the form of, or
        contain substantially the information contained in, Exhibit G attached
        hereto.

               In connection with any change described in this Section 2.02(h),
        the Auction Agent shall provide such further notice to such parties as
        is specified in Section 2.03 of the Auction Agent Agreement.

        Section 2.03. Additional Provisions Regarding the Interest Rates on the
Auction Rate Notes. The determination of a Variable Rate by the Auction Agent or
any other Person pursuant to the provisions of the applicable Section of this
Article II shall be conclusive and binding on the Registered Owners of the
Auction Rate Notes to which such Variable Rate applies, and the Issuer and the
Trustee may rely thereon for all purposes.

        In no event shall the cumulative amount of interest paid or payable on
the Auction Rate Notes (including interest calculated as provided herein, plus
any other amounts that constitute interest on the Auction Rate Notes under
applicable law, which are contracted for, charged, reserved, taken or received
pursuant to the Auction Rate Notes or related documents) calculated from the
Date of Closing of the Auction Rate Notes through any subsequent day during the
term of the Auction Rate Notes or otherwise prior to payment in full of the
Auction Rate Notes exceed the amount permitted by applicable law. If the
applicable law is ever judicially interpreted so as to render usurious any
amount called for under the Auction Rate Notes or related documents or otherwise
contracted for, charged, reserved, taken or received in connection with the
Auction Rate Notes, or if the redemption or acceleration of the maturity of the
Auction Rate Notes results in payment to or receipt by the Registered Owner or
any former Registered Owner of the Auction Rate Notes of any interest in excess
of that permitted by applicable law, then, notwithstanding any provision of the
Auction Rate Notes or related documents to the contrary, all excess amounts
theretofore paid or received with respect to the Auction Rate Notes shall be
credited on the principal balance of the Auction Rate Notes (or, if the Auction
Rate Notes have been paid or would thereby be paid in full, refunded by the
recipient thereof), and the provisions of the Auction Rate Notes and related
documents shall automatically and immediately be deemed reformed and the amounts
thereafter collectible hereunder and thereunder reduced, without the necessity
of the execution of any new document, so as to comply with the applicable law,
but so as to permit the recovery of the fullest amount otherwise called for
under the Auction Rate Notes and under the related documents.

        Section 2.04. Qualifications of Market Agent. The Issuer hereby directs
the Trustee to appoint PaineWebber Incorporated as the Market Agent. The Market
Agent shall be a member of the National Association of Securities Dealers, Inc.,
have a capitalization of at least $50,000,000 and be authorized by law to
perform all the duties imposed upon it by this Appendix A. The Market Agent may
resign and be discharged of the duties and obligations created by this Appendix
A by giving at least 30 days notice to the Issuer and the Trustee, provided that
such resignation shall not be effective until the appointment of a successor
market agent by the Issuer and the acceptance of such appointment by such
successor market agent. The Market Agent may be replaced at the direction of the
Issuer, by an instrument signed by an Authorized Officer, filed with the Market
Agent and the Trustee at least 30 days before the effective date of such
replacement, provided that such replacement shall not be effective until the
appointment of a successor market agent by the Issuer and the acceptance of such
appointment by such successor market agent.

        In the event that the Market Agent shall be removed or be dissolved, or
if the property or affairs of the Market Agent shall be taken under the control
of any state or federal court or administrative body because of bankruptcy or
insolvency, or for any other reason, and there is no Market Agent and the Issuer
shall not have appointed its successor as Market Agent, the Trustee,
notwithstanding the provisions of the first paragraph of this Section, shall be
deemed to be the Market Agent for all purposes of this Appendix A until the
appointment by the Issuer of the successor Market Agent. Nothing in this Section
shall be construed as conferring on the Trustee additional duties other than as
set forth herein.

The proceeds of such notes have been used by the Issuer, together with other
moneys of the Issuer, for the purpose of providing funds to finance the
acquisition of student loans, fund a reserve fund and to pay certain costs and
expenses in connection with the issuance of such notes. The Indenture provides
for the issuance of additional notes (the "Additional Notes") which may be
secured on a parity with or subordinate to the Class A Notes or the Class B
Notes as determined by the Issuer. The Class A Notes, the Class B Notes and any
Additional Notes are collectively referred to herein as the "Notes."

        Mandatory Redemption, Optional Redemption and Extraordinary Redemption.
This note is subject to mandatory redemption, optional redemption and
extraordinary redemption, all as described in the Indenture.

        Optional Purchase. The Issuer may purchase or cause to be purchased all
of the Notes on any Interest Payment Date on which the aggregate current
principal balance of the Notes shall be less than or equal to 10% of the initial
aggregate principal balance of the Notes on the Date of Issuance, at a purchase
price equal to the aggregate current principal balance of such Notes, plus
accrued interest on the Notes through the day preceding the Interest Payment
Date on which the purchase occurs.

        Notice of Redemption or Purchase. Notice of the call for redemption
shall be given by the Trustee by mailing a copy of the notice at least 15 days
prior to the redemption or purchase date to the Registered Owners of the Notes
to be redeemed in whole or in part at the address of such Registered Owner last
showing on the registration books. Failure to give such notice or any defect
therein shall not affect the validity of any proceedings for the redemption or
purchase of such Auction Rate Notes for which no such failure or defect occurs.
All Notes called for redemption or purchase will cease to bear interest after
the specified redemption or purchase date, provided funds for their payment are
on deposit at the place of payment at the time. If less than all Notes are to be
redeemed or purchased, Notes shall be selected for redemption or purchase as
provided in the Indenture.

        Swap Agreements. The Indenture provides that the Issuer may enter into
an interest rate swap or basis agreement between the Issuer and a swap provider
(a "Swap Counterparty"), as originally executed and as amended or supplemented,
or other interest rate hedge agreement between the Issuer and a Swap
Counterparty, as originally executed and as amended or supplemented, in each
case approved in writing by the Rating Agency, for the purpose of converting in
whole or in part the Issuer's variable interest rate liability on all or a
portion of the Notes bearing interest at a variable rate issued on a parity


                                       A-3
<PAGE>

therewith to a fixed rate liability or for the purpose of converting in whole or
in part the Issuer's fixed interest rate liability on all or a portion of any
Additional Notes bearing interest at a fixed rate issued on a parity therewith
to a variable rate liability. Payments due to a Swap Counterparty from the
Issuer pursuant to the applicable Swap Agreement (including, but not limited to,
payments in respect of an Early Termination Date, as defined in the applicable
Swap Agreement) are referred to herein as "Issuer Swap Payments."

        The principal of and interest on the Class A Notes and any Additional
Notes issued on a parity with the Class A Notes and any Issuer Swap Payments
secured on a parity with the Class A Notes are payable on a superior basis to
such payments on the Class B Notes and any Additional Notes issued on a parity
or subordinate to the Class B Notes; provided, however, that current principal
and interest may be paid on the Class B Notes and any Additional Notes issued on
a parity with the Class B Notes or subordinate to the Class B Notes if all
principal and interest payments due and owing at such time on the Class A Notes
and any Additional Notes issued on a parity with the Class A Notes and any
Issuer Swap Payments secured on a parity with the Class A Notes have been
previously made or provided for as provided in the Indenture.

        Reference is hereby made to the Indenture, copies of which are on file
in the Principal Office of the Trustee, and to all of the provisions of which
any Registered Owner of this note by his acceptance hereof hereby assents, for
definitions of terms; the description of and the nature and extent of the
security for the Notes; the Issuer's student loan origination and acquisition
program; the revenues and other money pledged to the payment of the principal of

the pledge; the conditions upon which the Indenture may be amended or
supplemented with or without the consent of the Registered Owners of the Notes
and any Swap Counterparty; the rights and remedies of the Registered Owner
hereof with respect hereto and thereto, including the limitations upon the right
of a Registered Owner hereof to institute any suit, action, or proceeding in
equity or at law with respect hereto and thereto; the rights, duties, and
obligations of the Issuer and the Trustee thereunder; the terms and provisions
upon which the liens, pledges, charges, trusts, and covenants made therein may
be discharged at or prior to the stated maturity or earlier redemption of this
note, and this note thereafter shall no longer be secured by the Indenture or be
deemed to be Outstanding, as defined in the Indenture, thereunder; and for the
other terms and provisions thereof.

        THE NOTES ARE LIMITED OBLIGATIONS OF THE ISSUER, PAYABLE SOLELY FROM,
AND FURTHER SECURED BY, THE TRUST ESTATE, AS DEFINED IN THE INDENTURE.

of the principal of and interest on this note or any claim based hereon or in
respect hereof or of the Indenture, against the Trustee, or any incorporator,
director, officer, employee, or agent of the Issuer, nor against the State of
Nevada, or any official thereof, but the obligation to pay all amounts required

covenants and acts required of the Issuer therein and herein shall be and remain
the responsibility and obligation of said Issuer, limited as herein set forth.

of the Indenture and any supplemental indenture may be made with the consent of
less than all of the Registered Owners of the Notes then outstanding or without
the consent of any of such Registered Owners (by reason of a change in the Act
or Regulation or to cure ambiguities or conflicts), but such modification or
alteration is not permitted to affect the maturity date, Stated Maturity,
amount, Interest Payment Date, or rate of interest on any outstanding Notes or
affect the rights of the Registered Owners of less than all of the Notes
outstanding.
        The Registered Owner hereof shall not have the right to demand payment
of this note or any interest hereon out of funds raised or to be raised by
taxation.

        Any capitalized term used herein and not otherwise defined herein shall
have the same meaning ascribed to such term in the herein defined Indenture
unless the context shall clearly indicate otherwise.

        It is hereby certified and recited that all acts and things required by
the laws of the State of Nevada to happen, exist, and be performed precedent to
and in the issuance of this note, and the passage of said resolution and the
execution of said Indenture, have happened, exist and have been performed as so
required.
