        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 Indenture 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 2003-1 Notes
        not less than 2 days prior thereto by first-class mail to each such
        Registered Owner as shown on the Indenture Trustee's registration books
        on the date selected by the Indenture Trustee, stating the date of the

        Trustee of any other Registered Owner owning at least $1,000,000

        2003-1 Notes shall be made in lawful money of the United States of
        America.

                (b) Except as otherwise provided in this Section, the Series

        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

        Initially, each Series 2003-1 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 2003-1 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
        Indenture 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 2003-1 Notes, (ii) the delivery to any Agent Member,
        beneficial owner of the Series 2003-1 Notes or other Person, other than
        the Securities Depository, of any notice with respect to the Series
        2003-1 Notes or (iii) the payment to any Agent Member, beneficial owner
        of the Series 2003-1 Notes or other Person, other than the Securities
        Depository, of any amount with respect to the principal of or interest
        on the Series 2003-1 Notes. So long as the certificates for the Series
        2003-1 Notes issued under this Supplemental Indenture are not issued
        pursuant to subsection (d) of this Section the Issuer and the Indenture
        Trustee may treat the Securities Depository as, and deem the Securities
        Depository to be, the absolute owner of the Series 2003-1 Notes for all
        purposes whatsoever, including, without limitation, (A) the payment of
        principal of and interest on such Series 2003-1 Notes, (B) giving
        notices of redemption and other matters with respect to such Series
        2003-1 Notes and (C) registering transfers with respect to such Series

        2003-1 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 Indenture Trustee with respect to any
        consent or other action to be taken by the Registered Owners, the Issuer
        or the Indenture 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 2003-1 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 Indenture Trustee that it is unwilling or unable to continue as
        Securities Depository with respect to any or all of the Series 2003-1
        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 Indenture Trustee shall
        authenticate and deliver certificates representing the Series 2003-1
        Notes as provided below. In addition, the Issuer may determine at any
        time that the Series 2003-1 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 2003-1 Notes. In
        such event, the Issuer shall execute and the Indenture Trustee shall
        authenticate and deliver certificates representing the Series 2003-1
        Notes as provided below. Certificates for the Series 2003-1 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 to the Issuer and the Indenture
        Trustee, and upon which written instructions the Indenture Trustee may
        rely without investigation. The Indenture Trustee shall promptly deliver
        such certificates representing the Series 2003-1 Notes to the Persons in
        whose names such Notes are so registered.

        first Note Payment Date to occur 15 days after the end of the
        Acquisition Period from amounts remaining on deposit in the 2003-1
        Acquisition/Redemption Account on the last day of the Acquisition Period
        representing proceeds of the Series 2003-1 Notes not used to acquire
        Eligible Loans, (ii) on the first Note Payment Date occurring each month
        for the Senior Notes from amounts on deposit in the 2003-1

        Financed Eligible Loans) and (iii) on the first Note Payment Date
        occurring each month for the Senior Notes prior to the time the Asset
        Release Test is met, as certified to the Indenture Trustee in an Issuer

        Order upon which Issuer Order the Indenture Trustee may conclusively
        rely, from moneys transferred to the Acquisition Redemption Fund from
        the Collection Fund pursuant to Section 5.03(b)(viii) of the Original
        Indenture, until such percentage is reached. Recoveries of Principal as
        a result of the voluntary sale of Financed Eligible Loans shall be used
        to redeem Series 2003-1 Notes pursuant to Section 2.02(b) below. In
        addition, subject to the provisions of Section 2.02(d) hereof, the
        2003-1 Notes are subject to mandatory redemption, in whole, at a
        redemption price equal to the principal balance being redeemed plus
        accrued interest and Carry-over Amounts, if any, to the date fixed for
        redemption after a Mandatory Auction of the Financed Eligible Loans
        pursuant to Section 2.02(f) hereof.

                (b) Optional Redemption of Series 2003-1 Notes. Subject to the
        provisions of Section 2.02(d) hereof, the Series 2003-1 Notes are
        subject to redemption at the option of the Issuer, from any available
        moneys in the Trust Estate, in whole or in part, on any Note Payment
        Date, at a redemption price equal to the principal amount thereof being
        redeemed, plus interest accrued, if any, and Carry-over Amounts, if any
        and as described in Appendix A hereto, to the date of redemption.

                (c) Notice of Redemption and Purchase. The Indenture 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 2003-1 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 10 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 2003-1 Notes for which no such failure or defect occurs.

                (d) Partial Redemption.

                        (i) If less than all of the Series 2003-1 Notes are to
                be redeemed pursuant to Section 2.02(a), 2.02(b) or 2.02(e)
                hereof, the Subclass of Series 2003-1 Notes to be redeemed shall
                be redeemed as directed by an Issuer Order. If less than all of
                the Series 2003-1 Notes of any Subclass of the Series 2003-1
                Notes are to be redeemed, such Series 2003-1 Notes to be
                redeemed shall be selected by lot in such manner as the
                Indenture Trustee shall determine.

                        (ii) In case a Series 2003-1 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 2003-1 Note for redemption in part only, the
                Issuer shall execute and the Indenture Trustee shall
                authenticate and deliver to the Registered Owner thereof, the
                cost of which shall be paid by the Issuer, a new Series 2003-1
                Note or Series 2003-1 Notes of the same series or Subclass,
                maturity and of Authorized Denominations, in an aggregate
                principal amount equal to the unredeemed portion of the Series
                2003-1 Note surrendered.

<PAGE>

                        (iii) All of the Class A Notes shall be redeemed prior
                to redemption of any Class B Notes; provided, however, upon the
                Indenture Trustee's receipt of an Issuer Order certifying that
                the ratio of the Aggregate Market Value of the Trust Estate to
                the Value of the Senior Notes then Outstanding exceeds 103%, or
                such other percentage that satisfies the Rating Agency
                Condition, the Indenture Trustee may redeem Class B Notes while
                Class A Notes remain Outstanding until the Aggregate Market
                Value of the Trust Estate to the Value of the Senior Notes
                equals the percentage described in this sentence after giving
                effect to the redemption of Class B Notes. The Indenture Trustee
                may conclusively rely upon such certification without duty to
                know, determine or further examine such Issuer Order.

                (e) Optional Purchase of Series 2003-1 Notes. The Issuer may,
        but is not required to, sell or finance all or a portion of the Financed
        Eligible Loans on the first Auction Date for any Subclass of the Series
        2003-1 Notes for which the Auction Rate established on such Auction Date
        exceeds the Net Loan Rate ("Optional Purchase"). If the Optional
        Purchase is exercised, the Financed Eligible Loans may be financed or
        sold to the Issuer or any designee of the Issuer (other than the Seller
        from which the Issuer originally acquired the Financed Eligible Loan) on
        the next Note Payment Date for such Subclass of the Series 2003-1 Notes,
        and the proceeds of such sale or financing will be used on such Note
        Payment Date to optionally redeem such Subclass of the Series 2003-1
        Notes as described in Section 2.02(b) above. The purchase price for the
        Optional Purchase and any Mandatory Auction as described in Section
        2.02(f) below, shall equal the minimum amount that, when combined with
        other available assets of the Trust Estate, is sufficient to: (i) reduce
        the outstanding principal balance of such Subclass of the Series 2003-1
        Notes to zero; (ii) pay to the Registered Owners of such Subclass the
        interest payable on the related Interest Payment Date, including
        Carry-over Amounts, if any; and (iii) pay any unpaid Program Expenses,
        if any (the "Minimum Purchase Price").

                (f) Mandatory Auction of Financed Eligible Loans and Mandatory
        Redemption of Series 2003-1 Notes.

                        (i) If the Issuer does not exercise its Optional
                Purchase of the Financed Eligible Loans, as described in Section
                2.02(e) above, by the fifth consecutive Auction Date for any
                Subclass of the Series 2003-1 Notes for which the Auction Rate
                established on such Auction Date exceeds the Net Loan Rate, all
                of the remaining Financed Eligible Loans shall be offered for
                sale by the Indenture Trustee (or its designated agent) prior to
                the next Interest Payment Date for such Subclass ("Mandatory
                Auction"). The Issuer, its affiliates and unrelated third
                parties (other than the Seller from which the Issuer originally
                acquired the Financed Eligible Loan) may offer to finance or
                purchase the Financed Eligible Loans in the Mandatory Auction.

                        (ii) If at least two bids are received, the Indenture
                Trustee (or its designated agent) will resolicit new bids from
                all participating bidders until only one bid remains or the
                remaining bidders decline to resubmit bids. The Indenture

                                       8
<PAGE>

                Trustee shall accept the highest of the remaining bids if it is
                equal to or in excess of both (A) the Minimum Purchase Price for
                all Subclasses of Series 2003-1 Notes then Outstanding and (B)
                the fair market value of such Financed Eligible Loans; provided,
                however, that if the Issuer is a bidder, the Issuer's bid need
                only satisfy the Minimum Purchase Price for all Subclasses of
                Series 2003-1 Notes then Outstanding. The Indenture Trustee may
                consult, and, at the direction of the Issuer, shall consult,
                with a financial advisor, including an underwriter of the Series
                2003-1 Notes or the Administrator, to determine if the fair
                market value of the Financed Eligible Loans has been offered.
                The proceeds of any such sale of Financed Eligible Loans shall
                be used to mandatorily redeem the Series 2003-1 Notes on the
                next Note Payment Date for each Subclass of Series 2003-1 Notes
                then Outstanding as described in Section 2.02(a) hereof. If the
                highest bid after the solicitation process is not equal to or in
                excess of both (A) the Minimum Purchase Price and (B) the fair
                market value of such Financed Eligible Loans (or only the
                Minimum Purchase Price in the case of a bid by the Issuer), the
                Indenture Trustee shall not complete the sale. If the sale is
                not completed, the Indenture Trustee may, but shall not be
                obligated to, solicit bids for the sale of the Financed Eligible
                Loans prior to succeeding Note Payment Dates, utilizing the
                procedures described above. The Indenture Trustee shall be
                obligated to make such solicitations if requested to do so by
                Issuer Order. If the Financed Eligible Loans are not sold
                pursuant to the Mandatory Auction, all amounts on deposit in the
                Collection Fund, after giving effect to all withdrawals
                described in Section 5.03(b)(i)-(x) of the Original Indenture,
                shall be utilized on the first Note Payment Date occurring each
                month for the Senior Notes (subject to Section 2.02(d)(ii)
                hereof) to make mandatory redemptions of the Series 2003-1
                Notes, in whole or in part, at a redemption price equal to the
                principal balance being redeemed plus accrued interest (but no
                Carry-over Amounts, if any) to the date fixed for redemption. If
                the Mandatory Auction is unsuccessful, the Auction Note Interest
                Rate on the Series 2003-1 Notes will be the Auction Note
                Interest Rate determined pursuant to the provisions of Appendix
                A hereto.

                        (iii) The Indenture Trustee shall be entitled to be paid
                by the Issuer additional reasonable compensation for its
                services in connection with any Mandatory Auctions conducted
                pursuant to this Section 2.02(f), whether or not successful, and
                to be reimbursed for all expenses (including without limitation
                the fees and expenses of counsel and of any agents designated by
                the Indenture Trustee to assist it conduct the Mandatory
                Auction) reasonably made or incurred in connection therewith. In
                the absence of the Indenture Trustee's negligence or willful
                misconduct, the Indenture Trustee shall not be liable for any
                action taken, suffered or omitted or for any error of judgment
                made by it in the performance of its duties under this Section
                2.02(f), including without limitation any liability if the
                Mandatory Auction is unsuccessful. The Indenture Trustee shall
                be entitled to be indemnified, as provided in Section 7.05 of
                the Original Indenture, for any loss, liability or expense
                incurred by the Indenture Trustee in connection with the
                performance of its duties under this Section 2.02(f).

        Section 2.03. Delivery of Series 2003-1 Notes. Upon the execution and
delivery of this Supplemental Indenture, the Issuer shall execute and deliver to

                                   ARTICLE II

                               TERMS AND ISSUANCE

        Section 2.01. Auction Rate and Carry-over Amounts. During the Initial

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. Unless otherwise
specified in an Issuer Order, 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) Monday
(unless such day is not followed by a Business Day, in which case on the next
succeeding day that is followed by a Business Day) of the following fourth week
in the case of the Class 2003A-1 Notes, the Class 2003A-2 Notes, the Class
2003A-11 Notes and the Class 2003A-12 Notes, (ii) Tuesday (unless such day is
not followed by a Business Day, in which case on the next succeeding day that is
followed by a Business Day) of the following fourth week in the case of the
Class 2003A-3 Notes, the Class 2003A-4 Notes, the Class 2003A-5 Notes and the
Class 2003A-6 Notes, (iii) Wednesday (unless such day is not followed by a
Business Day, in which case on the next succeeding day that is followed by a
Business Day) of the following fourth week in the case of the Class 2003A-7
Notes and the Class 2003A-8 Notes, and (iv) Thursday (unless such day is not
followed by a Business Day, in which case on the next succeeding day that is
followed by a Business Day) of the following fourth week in the case of the
Class 2003A-9 Notes, the Class 2003A-10 Notes, the Class 2003B-1 Notes and the
Class 2003B-2 Notes; provided, however, that in the case of the Auction Period

                                      A-1-11
<PAGE>

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) of this Appendix A. By way of example, if an Interest
Period ordinarily would end on a Tuesday, but the following Wednesday is not a
Business Day, the Interest Period will end on that Wednesday and the new
Interest Period will begin on Thursday.

        Notwithstanding the foregoing, unless otherwise specified in an Issuer
Order, if an Auction is scheduled to occur for the next Auction Period on a date
that was reasonably expected to be a Business Day, but such Auction does not
occur because such date is later not considered to be a Business Day, the
Auction shall nevertheless be deemed to have occurred, and the applicable
Auction Note Interest Rate in effect for the next Auction Period will be the
Auction Note Interest Rate in effect for the preceding Auction Period and such
Auction Period will generally be 28 days in duration, beginning on the calendar
day following the date of the deemed Auction and ending on (and including) the
applicable (i) Monday (unless such day is not followed by a Business Day, in
which case on the next succeeding day that is followed by a Business Day) of the
following fourth week in the case of the Class 2003A-1 Notes, the Class 2003A-2
Notes, the Class 2003A-11 Notes and the Class 2003A-12 Notes, (ii) Tuesday
(unless such day is not followed by a Business Day, in which case on the next
succeeding day that is followed by a Business Day) of the following fourth week
in the case of the Class 2003A-3 Notes, the Class 2003A-4 Notes, the Class
2003A-5 Notes and the Class 2003A-6 Notes, (iii) Wednesday (unless such day is
not followed by a Business Day, in which case on the next succeeding day that is
followed by a Business Day) of the following fourth week in the case of the
Class 2003A-7 Notes and the Class 2003A-8 Notes, and (iv) Thursday (unless such
day is not followed by a Business Day, in which case on the next succeeding day
that is followed by a Business Day) of the following fourth week in the case of
the Class 2003A-9 Notes, the Class 2003A-10 Notes, the Class 2003B-1 Notes and
the Class 2003B-2 Notes. If the preceding Auction Period was other than
generally 28 days in duration, the Auction Note Interest Rate for the deemed
Auction will instead be the rate of interest determined by the applicable
Broker-Dealer on equivalently rated auction securities with a comparable length
of auction period.

        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 Maximum 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-1-12
<PAGE>

        In accordance with Section 2.02(a)(iii)(B) and (C) of this Appendix A,
the Auction Agent shall promptly give written notice to the Indenture 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 Rate when such
rate is not the Auction Note Interest Rate, applicable to the Auction Rate
Notes. The Indenture Trustee shall notify the Registered Owners and the Issuer
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 Rate in effect for such Auction Period.

        If the Auction Rate for the Auction Rate Notes is greater than the
Maximum Rate, then the Variable Rate applicable to such Auction Rate Notes for
that Interest Period will be the Maximum Rate. If the Variable Rate applicable
to such Auction Rate Notes for any Interest Period is the Maximum Rate, the
Indenture 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 Indenture Trustee has received notice of
One-Month LIBOR from the Auction Agent, and if the Indenture Trustee shall not
have received such notice from the Auction Agent, then as determined by the
Indenture 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 Supplemental Indenture and 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 Indenture Trustee during such Interest Period in sufficient time for the
Indenture 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 Indenture Trustee, the
Indenture Trustee shall give written notice to each Registered Owner, the
Auction Agent and the Issuer 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. In addition to such Carry-over Amount, such notice shall
state, that, unless and until an Auction Rate Note has been redeemed (other than
by optional redemption), after which redemption all accrued Carry-over Amounts
(and all accrued interest thereon) that remain unpaid shall be canceled and no
Carry-over Amount (or interest accrued thereon) shall be paid with respect to
any redeemed 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
Indenture 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 optional redemption) if and to the extent
that (x) the Eligible Carry-over Make-Up Amount with respect to such subsequent
Interest Period is greater than zero, and (y) moneys are available pursuant to
the terms of the Indenture 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-1-13
<PAGE>

        The Carry-over Amount (and interest accrued thereon) for Auction Rate
Notes shall be paid by the Indenture 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 Revenue 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 Indenture 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 Indenture Trustee pays only a portion of
the Carry-over Amount (and any interest accrued thereon) on Auction Rate Notes,
the Indenture 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 Indenture Trustee in accordance with the provisions of the
immediately preceding paragraph, and the Indenture Trustee shall make payment of
the Carry-over Amount (and any interest accrued thereon) in the same manner as,
and from the same Fund 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 Maximum 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 Rate, the Maximum Rate shall be
determined by the securities dealer appointed by the Issuer capable of making
such a determination in accordance with the provisions of this Appendix A and
written notice of such determination shall be given by such securities dealer to
the Indenture Trustee.

        Section 2.02.  Auction Rate.

               (a) Determining the Auction 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

                             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 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 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 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) of this
                      Appendix A, the Auction Agent shall advise the Indenture
                      Trustee, the Broker-Dealers and the Issuer of the Maximum
                      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
                             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 Indenture Trustee of the Auction Note Interest
                      Rate.

                      (iv) Existing Owners shall continue to own the principal
               amount of Auction Rate Notes that are subject to Submitted Hold
               Orders. If the Maximum Rate is equal to or greater than the Bid
               Auction Rate and 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 Maximum Rate is less than the Auction Rate, the
               Maximum Rate will be the Auction Note Interest 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 Maximum 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 the
                      Maximum Rate is equal to or greater than the Bid Auction
                      Rate, and if the Maximum 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;

                                    (2) Existing Owners' 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

                             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)
                             of this Appendix A; 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) of this
                             Appendix A.

                             (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 Maximum Rate
                      is less than the Bid Auction Rate (in which case the
                      Auction Note Interest Rate shall be the Maximum Rate),
                      subject to the provisions of Section 2.02(a)(iv)(D) of
                      this Appendix A, 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

                                      A-1-23
<PAGE>
                             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 Indenture
               Trustee, as applicable, of the Auction Note Interest Rate, the
               Maximum 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
               Collection Fund to pay, or otherwise held by the Indenture
               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 Indenture Trustee shall
               promptly notify the Auction Agent of any such occurrence.

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

                      (i) The Indenture 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 Indenture 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 Indenture 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 Indenture Trustee shall pay
               to the Auction Agent, in immediately available funds out of
               amounts in the Collection 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 Indenture
               Trustee shall pay to the Auction Agent, in immediately available
               funds out of amounts in the Collection Fund, an amount equal to
               the Broker-Dealer Fee as calculated in the Broker-Dealer
               Agreement. The Indenture 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 Collection Fund.

               (c) Calculation of Maximum Rate, All Hold Rate, Applicable LIBOR
        Rate, and Non-Payment Rate. The Auction Agent shall calculate the
        Maximum Rate, Applicable LIBOR Rate, and All Hold Rate, as the case may
        be, on each Auction Date and shall notify the Indenture Trustee and the
        Broker-Dealers of the Maximum Rate, Applicable LIBOR 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 Indenture Trustee shall determine the Maximum Rate, Applicable

                                      A-1-25
<PAGE>
        LIBOR Rate, All Hold Rate and Non-Payment Rate for each such Interest
        Period. If the ownership of the Auction Rate Notes is no longer
        maintained in Book-entry Form by the Securities Depository, the
        Indenture Trustee shall calculate the Maximum 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 Indenture
        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 Indenture Trustee
        or the Auction Agent, as the case may be, of the Maximum Rate,
        Applicable LIBOR 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 Indenture Trustee of the Maximum Rate, Applicable
        LIBOR Rate and All Hold Rate.

               (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 Indenture 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 Indenture 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) of this Appendix A;

                             (B) pursuant to Section 2.01 of this Appendix A,
                      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 Indenture Trustee shall have given the notice or
        confirmation referred to in clause (i) of the preceding sentence, the
        Indenture 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

                                      A-1-26
<PAGE>
        or the old Interest Payment Date, by such means as the Indenture 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) Deutsche Bank Trust Company Americas is hereby
               appointed as Initial Auction Agent to serve as agent for the
               Issuer in connection with Auctions. The Indenture Trustee and the
               Issuer will, and the Indenture Trustee is hereby directed to,
               enter into the Initial Auction Agent Agreement with Deutsche Bank
               Trust Company Americas, 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 Indenture 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 Indenture Trustee,
               each Broker-Dealer and the Issuer. The Auction Agent may be
               removed at any time by the Indenture 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 Indenture
               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 Indenture Trustee, each Broker-Dealer 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 Indenture 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 Broker-Dealer
               Agreements with Banc of America Securities LLC and Deutsche Bank
               Securities Inc. as the initial Broker-Dealers. 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 Indenture 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
               applicable Broker-Dealer, 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
               Indenture Trustee, the Auction Agent, the applicable
               Broker-Dealer, 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.

                      (iii) An Auction Period Adjustment shall take effect only

               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

                                      A-1-28
<PAGE>
               certificate along with a copy of the written consent of the
               applicable Broker-Dealer 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 Maximum Rate and the Auction
               Period shall be the Auction Period determined without reference
               to the proposed change.

                      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 applicable Broker-Dealer,
        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
        applicable Broker-Dealer 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 applicable Broker-Dealer,
        such Broker-Dealer 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 Indenture 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
Indenture 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

                                      A-1-29
<PAGE>

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.

<PAGE>

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

        This note shall bear interest at an Auction Rate, all as determined in
Appendix A of the Series 2003-1 Supplemental Indenture.

        The principal of and interest on this note are payable in lawful money
of the United States of America. If the specified date for any payment of
principal or interest accrued to such specified date shall be a day other than a
Business Day then such payment may be made on the next succeeding Business Day,
with the same force and effect as if made on the specified date for such payment
without additional interest.

        Interest payable on this note shall be computed on the assumption that
each year contains 360 days and actual days elapsed.

        This note is one of a series of notes of the Issuer designated Student
Loan Asset-Backed Notes, [Senior Class
2003A-[1][2][3][4][5][6][7][8][9][10][11][12]] [Subordinate Class 2003B-[1][2]]
Auction Rate Notes, dated the Original Issue Date, in the aggregate original
principal amount of $_______________ (the "[Class
2003A-[1][2][3][4][5][6][7][8][9][10][11][12]] [Class 2003B-[1][2]] Notes")
which have been authorized by the Issuer under a certain resolution, and issued
by the Issuer pursuant to the Indenture. The Issuer is, simultaneously with the
[Class 2003A-[1][2][3][4][5][6][7][8][9][10][11][12]] [Class 2003B-[1][2]]
Notes, issuing $_______________ of its Student Loan Asset-Backed Notes, Senior
Class 2003A Notes in 12 subclasses (together with the Class
2003A-[1][2][3][4][5][6][7] [8][9][10][11][12] Notes, the "Class 2003A Notes")
and $____________ of its Student Loan Asset-Backed Notes, Subordinate Class
2003B-[1][2] in two subclasses (the "Class 2003B Notes," and together with the
Class 2003A Notes, the "Series 2003-1 Notes"). 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 OPTIONAL PURCHASE. This
note is subject to mandatory redemption, optional redemption and optional
purchase, all as described in the Indenture.

        NOTICE OF REDEMPTION OR PURCHASE. Notice of the call for redemption
shall be given by the Indenture Trustee by mailing a copy of the notice at least
10 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.

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

        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 Derivative
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 Derivative 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
at the designated corporate trust office of the Indenture 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 and interest on the Notes; the nature and extent and
manner of enforcement 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 Reciprocal Payor; 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 Indenture 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.

        No recourse, either directly or indirectly, shall be had for the payment
of the principal of and interest on this note or any claim based hereon or in
respect hereof or of the Indenture, against the Indenture Trustee, or any
incorporator, director, officer, employee, or agent of the Issuer, nor against
the State of Nebraska, or any official thereof, but the obligation to pay all
amounts required by the Indenture securing this note and the obligation to do
and perform the 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.

Trustee, as registrar, upon surrender of this note for transfer at the
designated corporate trust office of the Indenture Trustee, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Indenture Trustee duly executed by, the Registered Owner hereof or his attorney
duly authorized in writing, and thereupon one or more new Notes of the same
series, Stated Maturity, of authorized denominations, bearing interest at the
same rate, and for the same aggregate principal amount will be issued to the
designated transferee or transferees. At the option of the Registered Owner, any
Note may be exchanged for other Notes in authorized denominations upon surrender

Note or Notes so surrendered will be issued to the Registered Owner of the Note
or Notes so surrendered; and the Note or Notes so surrendered shall thereupon be
cancelled by the Indenture Trustee.

        Notwithstanding the foregoing, so long as the ownership of the Notes is
maintained in book-entry form by The Depository Trust Company (the "Securities
Depository") or a nominee thereof, this note may be transferred in whole but not
in part only to the Securities Depository or a nominee thereof or to a successor
Securities Depository or its nominee.

        The Issuer, the Indenture Trustee, and any agent of either of them shall
treat the Person in whose name this note is registered as the Registered Owner
hereof (a) on the record date for purposes of receiving timely payment of
interest hereon, and (b) on the date of surrender of this note for purposes of
receiving payment of principal hereof at its stated maturity and (c) for all
other purposes, whether or not this note is overdue, and neither the Issuer, the
Indenture Trustee, nor any such agent shall be affected by notice to the
contrary.

        To the extent permitted by the Indenture, modifications or alterations
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 Nebraska 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.
