                      Third Supplemental Indenture of Trust

     This Third Supplemental Indenture of Trust (this "Supplemental Indenture")
dated as of December    , 2002 is by and between Education Funding Capital
                     ---
Trust-I, a Delaware business trust (the "Issuer"), Fifth Third Bank, a banking
corporation organized under the laws of the State of Ohio, as indenture trustee
(the "Indenture Trustee"), and Fifth Third Bank, a banking corporation organized
under the laws of the State of Ohio, as Trust Eligible Lender Trustee (the
"Trust Eligible Lender Trustee"). All capitalized terms used in these preambles,
recitals and granting clauses shall have the same meanings assigned thereto in
the Indenture (defined below).

                              W I T N E S S E T H:

     Whereas, the Issuer has previously entered into an Indenture of Trust dated
as of May 1, 2002 (the "Indenture") among the Issuer, the Indenture Trustee and
the Trust Eligible Lender Trustee;

     Whereas, pursuant to Section 7.01 of the Indenture, the Issuer desires to
enter into this Supplemental Indenture to amend the Indenture as set forth
herein; and

     Whereas, the Indenture Trustee has agreed to accept the trusts herein
created upon the terms herein set forth;

     Now, Therefore, in consideration of the foregoing, the parties hereto agree
that the foregoing recitals are incorporated herein by reference and as follows:

     Section 1. Appendix A of the Indenture is hereby amended to add the
following defined term:

          "Subordinated Issuer Termination Payment" shall mean any early
     termination payment required to be made by or on behalf of the Issuer
     pursuant to a Derivative Product, excluding, however, early termination
     payments required to be made by the Issuer in respect of (i) a payment
     default by the Issuer under the Derivative Product and (ii) the bankruptcy
     or insolvency of the Issuer.

     Section 2. Section 2.03 of the Indenture is hereby amended and restated in
its entirety to read as follows:

          The Issuer hereby authorizes and directs the Indenture Trustee to
     acknowledge and agree to any Derivative Product hereafter entered into by
     the Issuer and a Counterparty under which (a) the Issuer may be required to
     make, from time to time, Issuer Derivative Payments and (b) the Indenture
     Trustee may receive, from time to time, Counterparty Derivative Payments
     for the account of the Issuer. No Derivative Product shall be entered into
     unless the Indenture Trustee shall have received a Rating Confirmation from
     each Rating Agency that such Derivative

<PAGE>

     Product will not adversely affect the Rating on any of the Notes. Anything
     in this Indenture to the contrary notwithstanding, any Revenues
     representing Counterparty Derivative Payments of a Counterparty shall not
     be available to make an Issuer Derivative Payment to another Counterparty
     or to pay any other amounts owed to such Counterparty pursuant to a
     Derivative Product.

          No later than the fourth Business Day immediately preceding each
     Derivative Payment Date the Issuer shall give written notice to the
     Indenture Trustee stating (a) the amount and payer of each Counterparty
     Derivative Payment, if any, due to be received by the Indenture Trustee for
     the account of the Issuer on or before such Derivative Payment Date and (b)
     the amount and payee of each Issuer Derivative Payment, if any, to be paid
     on or before such Derivative Payment Date. If the Indenture Trustee fails
     to receive such written notification from the Issuer by the end of the
     third Business Day immediately preceding such Derivative Payment Date, it
     shall immediately notify the Issuer of such fact in writing.

          On or before each Derivative Payment Date and in accordance with the
     written notification received from the Issuer, the Indenture Trustee shall
     deposit all moneys received representing Counterparty Derivative Payments
     into the Revenue Fund to be applied in accordance with the provisions of
     Section 4.03 hereof. The Indenture Trustee shall notify the Issuer on such
     Business Day, if (a) the amount received from any Counterparty is not equal
     to the amount specified in the written notification of the Issuer, (b) no
     amount is received from such Counterparty or (c) the amount received is not
     received in immediately available funds.

          On or before any Derivative Payment Date with respect to which an
     Issuer Derivative Payment is due in accordance with the written
     notification received from the Issuer or, with respect to a payment in
     respect of an early termination date due from the Issuer pursuant to the
     terms of a Derivative Product, the Indenture Trustee shall make payment to
     the appropriate Counterparty from moneys in the Revenue Fund of the amount
     of the Issuer Derivative Payment specified in such written notification of
     the Issuer due on such date by the deposit or wire transfer of immediately
     available funds to the credit of the account of such Counterparty specified
     in such written notification of the Issuer, but only to the extent such
     payment will not result in a deficiency in the amount due on the next
     succeeding Payment Date to the holders of any class of Obligations having a
     priority equal to or higher than the Derivative Product in respect of which
     such Issuer Derivative Payment is due.

          If any payment to a Counterparty described in the immediately
     preceding paragraph would result in a deficiency in the amounts required to
     make payments to the holders of the Obligations referred to in that
     paragraph on such Payment Date, then the Indenture Trustee shall delay the
     making of such payment to such Counterparty until the first date on which
     no deficiency would result from such payment and the Indenture Trustee has
     been notified in writing to make such payment.

     The 2002 Series A1&B1 Notes (collectively, the "Auction Rate Notes") shall
be dated their Date of Issuance and shall bear interest from the most recent
Payment Date (as defined in Appendix A to this Supplemental Indenture) to which
interest has been paid on the Unregistered Notes of the Series for which the
Registered Notes of the same Series are exchanged. The 2002 Series A1&B1 Notes
shall mature on June 1, 2042. Interest on the Auction Rate Notes shall be
computed on the basis of a 360-day year and actual days elapsed. The terms of
and definitions related to the Auction Rate Notes are found in Article I hereof
and Appendix A to this Supplemental Indenture. No premium payments shall be paid

     The principal of the 2002 Series A1&B1 Notes due at its Stated Maturity or
redemption in whole shall be payable at the Corporate Trust Office of the
Indenture Trustee, or such other location as directed by the Indenture Trustee,
or at the principal office of its successor in trust upon presentation and
surrender of the 2002 Series A1&B1 Notes. Payment of interest and principal paid
subject to a redemption on any 2002 Series A1&B1 Note shall be made to the
Noteholder thereof by check or draft mailed on the Payment Date by the Indenture
Trustee to the Noteholder at his address as it last appears on the registration
books kept by the Indenture Trustee at the close of business on the Record Date
for such Payment Date, but any such interest not so timely paid or duly provided
for shall cease to be payable to the Noteholder thereof at the close of business
on the Record Date and shall be payable to the Noteholder 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
Noteholders of the 2002 Series A1&B1 Notes not less than ten (10) days prior
thereto by first-class mail to each such Noteholder as shown on the Indenture
Trustee's registration books on the date selected by the Indenture 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 Indenture Trustee
of any other Noteholder owning at least $1,000,000 principal amount of the 2002
Series A1&B1 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 Indenture Trustee for such purpose. All payments
on the 2002 Series A1&B1 Notes shall be made in lawful money of the United
States of America.

     (a) Except as otherwise provided in this Section, the Series A1 Notes and
Series B1 Notes in the form of one global note for each Series 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 A1 Note and Series B1
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 A1 Notes and Series B1 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

<PAGE>

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."

     (b) 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 A1 Notes and Series
B1 Notes, (ii) the delivery to any Agent Member, beneficial owner of the Series
A1 Notes and Series B1 Notes or other Person, other than the Securities
Depository, of any notice with respect to the Series A1 Notes and Series B1
Notes or (iii) the payment to any Agent Member, beneficial owner of the Series
A1 Notes and Series B1 Notes or other Person, other than the Securities
Depository, of any amount with respect to the principal of or interest on the
Series A1 Notes and Series B1 Notes. So long as the certificates for the Series
A1 Notes and Series B1 Notes issued under this Supplemental Indenture are not
issued pursuant to subsection (c) 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 A1 Notes and Series B1 Notes
for all purposes whatsoever, including, without limitation, (A) the payment of
principal of and interest on such Series A1 Notes and Series B1 Notes, (B)
giving notices of redemption and other matters with respect to such Series A1
Notes and Series B1 Notes and (C) registering transfers with respect to such
Series A1 Notes and Series B1 Notes. In connection with any notice or other
communication to be provided to the Noteholders 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 Noteholders, 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 A1
Notes and Series B1 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 Noteholder.

     (c) 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 A1 Notes and Series B1 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 (a) and (b) 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 A1 Notes and
Series B1 Notes as provided below. In addition, the Issuer may determine at any
time that the Series A1 Notes and Series B1 Notes shall no longer be represented
by global certificates and that the provisions of subsections (a) and (b) of
this Section shall no longer apply to the Series A1 Notes and Series B1 Notes.
In such event, the Issuer shall execute and the Indenture Trustee shall
authenticate and deliver certificates representing the Series A1 Notes and
Series B1 Notes as provided below. Certificates for the Series A1 Notes and
Series B1 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

<PAGE>

instructions the Indenture Trustee may rely without investigation. The Indenture
Trustee shall promptly deliver such certificates representing the Series A1
Notes and Series B1 Notes to the Persons in whose names such Notes are so
registered.

     Section 2.02 Redemption of the 2002 Series A1&B1 Notes.

     (a) Mandatory Redemption. If on any Determination Date the Parity
Percentage is not equal to at least the Required Parity Percentage, the 2002
Series A1&B1 Notes are subject to mandatory redemption, in whole or in part, on
any interest Payment Date from Revenues on deposit in the Principal Fund;
provided, however, that during any Revolving Period, upon Issuer Order, after
any transfer to the Operating Fund in respect of Program Expenses and after the
transfers required by Sections 4.03(b)(i) through (v) of the Indenture, moneys
remaining on deposit in the Revenue Fund shall be transferred to the Acquisition
Fund and used for the acquisition or origination of other Student Loans.

     The 2002 Series A1&B1 Notes are also subject to mandatory redemption, in
whole or in part, on any interest Payment Date, from Revenues representing
Recoveries of Principal on deposit in the Principal Fund or from Revenues
transferred to the Principal Fund pursuant to Section 4.03(b)(ix) of the
Indenture. Series B1 Notes shall be redeemed only to the extent that after such
payment the Senior Parity Percentage shall not be less than the Required Senior
Parity Percentage.

     (b) Optional Redemption of 2002 Series A1&B1 Notes. The 2002 Series A1&B1
Notes are subject to redemption, in whole or in part, at the option of the
Issuer on any regularly scheduled interest Payment Date. Carryover amounts and
interest on the carryover amounts will be paid prior to any optional redemption
of 2002 Series A1&B1 Notes. To the extent funds are available in the Interest
Fund to pay carryover amounts and interest on carryover amounts on any Payment
Date, such funds will be allocated first to pay carryover amounts and interest
on carryover amounts on 2002 Series A1&B1 Notes subject to mandatory redemption
on such Payment Date. Any carryover amount and interest on the carryover amount
not paid on the date a 2002 Series A1&B1 Note is redeemed pursuant to mandatory
redemption will be cancelled and not paid on that Note on any subsequent date.

     (c) Redemption Price. Any 2002 Series A1&B1 Notes redeemed pursuant to
Section 2.02(a) or (b) hereof shall be redeemed at a price equal to the
principal balance of such Notes plus accrued interest to the date of redemption.

     (d) Limitation of Redemption of Series B1 Notes. The Series B1 Notes that
are otherwise subject to optional or mandatory redemption shall be redeemed only
if, as of the date of selection of Series B1 Notes for redemption and after
giving effect to such redemption, the Senior Parity Percentage will be equal to
at least the Required Senior Parity Percentage, and the Parity Percentage will
be equal to at least the Required Parity Percentage.

     (e) Redemption of Additional Series of Notes. The Issuer shall determine in
a Supplemental Indenture the redemption provisions applicable to additional
series of notes issued under such Supplemental Indenture. The Issuer may
determine to redeem such additional series of notes before redeeming the 2002
Series A1&B1 Notes.

<PAGE>

     (f) Notice of Redemption. The Indenture Trustee shall cause notice of any
redemption to be given by mailing a copy of the notice by first-class mail to
the Auction Agent and the Noteholder of any 2002 Series A1&B1 Notes designated
for redemption in whole or in part, at their address as the same shall last
appear upon the registration books, in each case not less than 12 days prior to
the redemption date; provided, however, that failure to give such notice, or any
defect therein, shall not affect the validity of any proceedings for the
redemption of such 2002 Series A1&B1 Notes for which no such failure or defect
occurs.

     (g) Partial Redemption. If less than all of the 2002 Series A1&B1 Notes are
to be redeemed or purchased pursuant to Section 2.02(a) or (b) hereof, the
Series of Notes to be redeemed shall be determined by the Issuer; provided,
however, in the absence of any direction by the Issuer, the Series of Notes to
be redeemed shall be selected first from the Series B1 Notes to the extent
permitted hereby and, thereafter, in descending numerical order of the series
designation; provided, however, that the Issuer shall not direct the Indenture
Trustee to redeem any Series of Notes prior to the expiration of the Initial
Period (as defined in Appendix A to this Supplemental Indenture) applicable to
that Series. If less than all Outstanding Notes of any Series of 2002 Series
A1&B1 Notes are to be redeemed, the particular Notes of that Series to be
redeemed will be determined by lot in such manner as the Indenture Trustee shall
determine. In case a 2002 Series A1&B1 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 2002 Series A1&B1 Note for redemption in
part only, the Issuer shall execute and the Indenture Trustee shall authenticate
and deliver to the Noteholder thereof, the cost of which shall be paid by the
Issuer, a new 2002 Series A1&B1 Note or 2002 Series A1&B1 Notes of the same
Series, maturity and of Authorized Denominations, in an aggregate principal
amount equal to the unredeemed portion of the 2002 Series A1&B1 Note
surrendered.

     Section 2.03 Delivery of 2002 Series A1&B1 Notes. Upon the execution and
delivery of this Supplemental Indenture, the Issuer shall execute and deliver to
the Indenture Trustee and the Indenture Trustee shall authenticate the 2002
Series A1&B1 Notes and deliver the 2002 Series A1&B1 Notes to The Depository

     Section 2.04 Trustee's Authentication Certificate. The Indenture Trustee's
authentication certificate upon the 2002 Series A1&B1 Notes shall be
substantially in the forms provided in Exhibits A-1 and A-2 hereto. No 2002
Series A1&B1 Note shall be secured hereby or entitled to the benefit hereof, or
shall be valid or obligatory for any purpose, unless a certificate of
authentication, substantially in such form, has been duly executed by the
Indenture Trustee at the written direction of the Issuer; and such certificate
of the Indenture Trustee upon any 2002 Series A1&B1 Note shall be conclusive
evidence and the only competent evidence that such Note has been authenticated

shall be deemed to have been duly executed by it if manually signed by an
authorized officer of the Indenture Trustee, but it shall not be necessary that
the same person sign the certificate of authentication on all of the 2002 Series
A1&B1 Notes issued hereunder.

     Section 2.05 No Proceeds From Issuance of 2002 Series A1&B1 Notes. The
Issuer will not receive any proceeds upon the issuance and delivery of the 2002
Series A1&B1 Notes.

     Section 2.06 Excess Reserve Fund Amounts. On any date on which the amount
on deposit in the Reserve Fund exceeds the Reserve Fund Requirement, the
Indenture Trustee, at the direction of the Administrator, shall transfer such
excess from the Reserve Fund to the Revenue Fund for application on the next
Payment Date.

     Section 2.07 Forms of 2002 Series A1&B1 Notes. The 2002 Series A1&B1 Notes

each with such variations, omissions and insertions as may be necessary.

     Section 2.08 Regarding Acquisition Fund. The Indenture Trustee shall have
transferred to the Revenue Fund all moneys remaining in the Acquisition Fund
immediately after December 31, 2002; provided, however, that the transfer of
such moneys may be delayed upon receipt of a Rating Confirmation with respect to
such delay.

     requirements of this Section 11.05, except that, in the case of any such
     application or request as to which the furnishing of such documents is
     specifically required by any provision of the Indenture or in this
     Supplemental Indenture, no additional certificate or opinion need be

     of each such signatory, such condition or covenant has been complied with.

          (b) Prior to the deposit of any property or securities with the
     Indenture Trustee that is to be made the basis for the release of any
     property subject to the lien created by the Indenture, the Issuer shall, in
     addition to any obligation imposed in Section 11.05(a) or elsewhere in the
     Indenture or in this Supplemental Indenture, furnish to the Indenture

     counsel, such action has been taken with respect to the recording and
     filing of the Indenture and any other requisite documents, and with respect
     to the execution and filing of any financing statements and continuation
     statements, as are necessary to perfect and make effective the lien and
     security interest in favor of the Indenture Trustee, for the benefit of the
     Indenture Trustee, created by the Indenture or in this Supplemental
     Indenture in the property or securities to be so deposited, and reciting
     the details of such action, or stating that, in the opinion of such

     rating of any of the Notes.

     Trustee a Certificate certifying or stating the opinion of any signer
     thereof as to the matters described in paragraph (b) above, the Issuer
     shall also furnish to the Indenture Trustee an Independent Certificate as
     to the same matters, if the fair value to the Issuer of the property to be
     so deposited and of all other such property made the basis of any such
     withdrawal or release since the commencement of the then-current fiscal
     year of the Issuer, as set forth in the certificates delivered pursuant to
     paragraph (b) above and this paragraph (c), is ten percent (10%) or more of
     the Outstanding principal amount of the Notes, but such a certificate need
     not be furnished with respect to any property so deposited, if the fair
     value thereof set forth in the related Certificate is less than $25,000 or
     less than one percent (1%) of the Outstanding Amount of the Notes.

          (d) Other than with respect to any release described in clause (1) or

     released from the lien created by the Indenture, the Issuer shall also
     furnish to the Indenture Trustee a Certificate certifying or stating the
     opinion of each person signing such Certificate as to the fair value
     (within 90 days of such release) of the property or securities proposed to
     be released and stating that in the opinion of such person the proposed
     release will not impair the security created by this Indenture in
     contravention of the provisions hereof.

          (e) Whenever the Issuer is required to furnish to the Indenture
     Trustee a Certificate certifying or stating the opinion of any signer
     thereof as to the matters described in paragraph (d) above, the Issuer
     shall also furnish to the Indenture Trustee an Independent Certificate as
     to the same matters, if the fair value to the Issuer of the property

<PAGE>

     or securities or of all other property or securities (other than property
     described in clauses (1) and (2) of paragraph (f) below) released from the
     lien created by the Indenture since the commencement of the then-current
     fiscal year of the Issuer, as set forth in the certificates delivered
     pursuant to paragraph (d) above and this paragraph (e), equals ten percent
     (10%) or more of the Outstanding Amount of the Notes, but such a
     certificate need not be furnished with respect to any release of property
     or securities, if the fair value thereof set forth in the related
     Certificate is less than $25,000 or less than one percent (1%) of the
     Outstanding Amount of the Notes.

          (f) Notwithstanding any other provision of this Section 11.05, the
     Issuer may, without compliance with the other provisions of this Section
     11.05, (1) collect, liquidate, sell or otherwise dispose of Financed

     condition of granting such application, or as evidence of the Issuer's
     compliance with any term hereof, it is intended that the truth and
     accuracy, at the time of the granting of such application or at the
     effective date of such certificate or report, as the case may be, of the
     facts and opinions stated in such document shall in such case be conditions
     precedent to the right of the Issuer to have such application granted or to
     the sufficiency of such certificate or report. The foregoing, shall not,
     however,

     be construed to affect the Indenture Trustee's right to rely upon the truth

                               Terms and Issuance

     Section 2.01 Auction Rate and Carry-over Amounts. During the Initial
Period, each of the Series A1-1 Notes, the Series A1-2 Notes, the Series A1-3
Notes and the Series A1-4 Notes shall bear interest at the Initial Rate for such
Series. Each of the Series A1-5 Notes, Series A1-6 Notes, Series A1-7 Notes,
Series A1-8 Notes, Series A1-9 Notes, Series A1-10 Notes, Series A1-11 Notes,
Series A1-12 Notes, Series A1-13 Notes, Series B1-1 Notes and Series B1-2 Notes
shall bear interest at the Auction Note Interest Rate in effect for the Auction
Period corresponding to each of the Series A-5 Notes, Series A-6 Notes, Series
A-7 Notes, Series A-8 Notes, Series A-9 Notes, Series A-10 Notes, Series A-11
Notes, Series A-12 Notes, Series A-13 Notes, Series B-1 Notes and Series B-2
Notes, respectively, as of the Exchange Date.

     Each Series of Auction Rate Notes, except (a) with respect to an Auction
Period Adjustment, or (b) during the Initial Period with respect to the Series
A1-1 Notes, the Series A1-2 Notes, the Series A1-3 Notes and the Series A1-4
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 of this Appendix A.

     For the Auction Rate Notes during the Initial Period and each Auction
Period, interest at the applicable Auction Note 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
(except during the Initial Period with respect to the Series A1-1 Notes, the
Series A1-2 Notes, the Series A1-3 Notes and the Series A1-4 Notes) for each
Auction Period until an Auction Period Adjustment, if any, shall be determined
as described below. Each such Auction Period shall commence on and include the
day following the expiration of the immediately preceding Auction Period and
terminate on and include (i) the first Business Day of the following fourth week
in the case of the Series A1-8 Notes, the Series A1-10 Notes, the Series A1-11
Notes and the Series A1-13 Notes, (ii) the second Business Day of the following
fourth week in the case of the Series A1-1 Notes, the Series A1-2 Notes, the
Series A1-3 Notes and the Series A1-4 Notes, and (iii) the third Business Day of
the following fourth week in the case of the Series A1-12 Notes and the Series

Period that immediately follows the Initial Period for each of the Series A1-1
Notes, the Series A1-2 Notes, the Series A1-3 Notes and the Series A1-4 Notes,
shall commence on the Interest 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; provided that, if on any Interest Rate Determination
Date, an Auction is not held for any reason, the following Business Day shall be
considered the Interest Rate Determination Date and an Auction is to be held on
such date. If an Auction is not held for any reason on such date, then the
Auction Note Interest Rate on such Auction Rate Notes for the next succeeding
Auction Period shall be the applicable Cap Rate.

                                      A-8

     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 Cap Rate; 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.

     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, upon request, notify the Noteholders 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 Net Loan
Rate, then the Auction Note Interest Rate applicable to such Auction Rate Notes
for that Interest Period will be the Net Loan Rate and the Issuer 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 Indenture Trustee) from the 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 Issuer during such
Interest Period in sufficient time for the Indenture Trustee to give notice to
each Noteholder of such Carry-over Amount as required in the next succeeding
sentence. Not less than four days before the Payment Date for an Interest Period
with respect to which such Carry-over Amount has been calculated by the Issuer,
the Indenture Trustee shall give written notice to each Noteholder, the Auction
Agent and the Issuer, in the form provided by the Issuer, of the Carry-over
Amount applicable to each Auction Rate Note, which written notice may accompany
the payment of

                                      A-9

<PAGE>

interest made to the Noteholder on such Payment Date. 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 such 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 pursuant to an Issuer Order on an Auction
Rate Note on the earliest of (i) the date of defeasance of any of the Auction
Rate Notes or (ii) the first occurring Payment Date with respect to the Auction
Rate Note (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 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.

     The Carry-over Amount (and interest accrued thereon) for Auction Rate Notes
shall be paid by the Indenture Trustee pursuant to an Issuer Order 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 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 Payment Date there are
sufficient moneys in the Revenue Fund to pay all interest due on the Auction
Rate Notes on such Payment Date, to redeem any Auction Rate Notes required to be
redeemed on such Payment Date in accordance with the Indenture and to fund
amounts required to be added to the Reserve Fund on such Payment Date. Any
Carry-over Amount (and any interest accrued thereon) on any Auction Rate Note
that is due and payable on a Payment Date, which Auction Rate Note is to be
redeemed (other than by optional redemption) on said Payment Date, shall be paid
to the Noteholder thereof on said 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)
that is not yet due and payable on said Payment Date shall be cancelled with
respect to said Auction Rate Note that is to be redeemed (other than by optional
redemption) on said Payment Date and shall not be paid on any succeeding 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 Payment Date or Dates, as
necessary, if and to the extent that the conditions in the second preceding
sentence are satisfied. On any 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 Noteholder of
such Auction Rate Note receiving such partial payment of the Carry-over Amount
remaining unpaid on such Auction Rate Note.

     The 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, 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

                                      A-10

<PAGE>

Notes on a 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 Cap 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 Cap Rate, the Cap 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 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 that 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, that such Existing Owner offers to sell if the Auction
               Note Interest

                                      A-11

<PAGE>

               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 that 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 that 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.

     The statement of an Existing Owner or a Potential Owner referred to in (1)
or (2) of this paragraph (A) is herein referred to as an "Order," and each
Existing Owner and each Potential Owner placing an Order is herein referred to
as a "Bidder"; an Order described in clause (1)a. is herein referred to as a
"Hold Order"; an Order described in clauses (1)b. and (2) is herein referred to
as a "Bid"; and an Order described in clause (1)c. is herein referred to as a
"Sell Order."

          (B) (1) Subject to the provisions of Section 2.02(a)(ii) of this
     Appendix A, a Bid by an Existing Owner shall constitute an irrevocable
     offer to sell:

                    a. the principal amount of Outstanding Auction Rate Notes
               specified in such Bid if the Auction Note Interest Rate
               determined as provided in this Section 2.02(a) shall be less than
               the rate specified therein; or

                    b. such principal amount, or a lesser principal amount of
               Outstanding Auction Rate Notes to be determined as set forth in
               Section 2.02(a)(iv)(A)(4) of this Appendix A, if the Auction Note
               Interest Rate determined as provided in this Section 2.02(a)
               shall be equal to the rate specified therein; or

                    c. such principal amount, or a lesser principal amount of
               Outstanding Auction Rate Notes to be determined as set forth in
               Section 2.02(a)(iv)(B)(3) of this Appendix A, if the rate
               specified therein shall be higher than the applicable Maximum
               Rate and Sufficient Bids have not been made.

               (2) Subject to the provisions of Section 2.02(a)(ii) of this
          Appendix A, a Sell Order by an Existing Owner shall constitute an
          irrevocable offer to sell:

                                      A-12

<PAGE>

                    a. the principal amount of Outstanding Auction Rate Notes
               specified in such Sell Order; or

                    b. such principal amount, or a lesser principal amount of
               Outstanding Auction Rate Notes set forth in Section
               2.02(a)(iv)(B)(3) of this Appendix A, if Sufficient Bids have not
               been made.

               (3) Subject to the provisions of Section 2.02(a)(ii) of this
          Appendix A, a Bid by a Potential Owner shall constitute an irrevocable
          offer to purchase:

                    a. the principal amount of Outstanding Auction Rate Notes
               specified in such Bid if the Auction Note Interest Rate
               determined as provided in this Section 2.02(a) shall be higher
               than the rate specified in such Bid; or

                    b. such principal amount, or a lesser principal amount of
               Outstanding Auction Rate Notes set forth in Section
               2.02(a)(iv)(A)(5) of this Appendix A, if the Auction Note
               Interest Rate determined as provided in this Section 2.02(a)
               shall be equal to the rate specified in such Bid.

          (ii) (A) Each Broker-Dealer shall submit in writing to the Auction
     Agent prior to the Submission Deadline on each Auction Date all Orders
     obtained by such Broker-Dealer and shall specify with respect to each such
     Order:

               (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 Rate Notes, if any,
               subject to any Bid placed by such Existing Owner and the rate
               specified in such Bid; and

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

               and

               (4) to the extent such Bidder is a Potential Owner, the rate
          specified in such Potential Owner's Bid.

                                      A-13

<PAGE>

               (B) If any rate specified in any Bid contains more than three
          figures to the right of the decimal point, the Auction Agent shall
          round such rate up to the next higher one thousandth of 1%.

               (C) If an Order or Orders covering all Outstanding Auction Rate
          Notes owned by an Existing Owner is not submitted to the Auction Agent
          prior to the Submission Deadline, the Auction Agent shall deem a Hold
          Order to have been submitted on behalf of such Existing Owner 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 Indenture 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 (ii);

                         b. subject to subclause (2)a. of this clause (E), 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 (2)a. and (2)b. of this clause
                    (E), if more than one Bid with different rates are submitted
                    on behalf of

                                      A-14

<PAGE>

                    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 (E) 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 (E) 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:

                                      A-15

<PAGE>

                    (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 that, 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 Net Loan Rate, Maximum Rate and the All Hold Rate and
          the components thereof on the Auction Date. Based on such
          determinations, the Auction Rate for the next succeeding Interest
          Period will be established 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, which rate shall be the
          lesser of (x) the Auction Rate and (y) the applicable Maximum Rate.

          (iv) Existing Owners shall continue to own the principal amount of
     Auction Rate Notes that are subject to Submitted Hold Orders. If the Net
     Loan 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 applicable
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 (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:

                                      A-17

<PAGE>

                    (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)(A), 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) 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

                                      A-18

<PAGE>

               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 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

                                      A-19

<PAGE>

          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, the Net Loan 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 Revenue 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 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 a 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

                                      A-20

<PAGE>

     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 Exchange Date, the Indenture 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
     as set forth in the Servicer's Report. 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 Revenue Fund,
     an amount equal to the Broker-Dealer Fee as calculated in the Auction Agent
     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 Revenue
     Fund.

     (c) Calculation of Maximum Rate, All Hold Rate, Net Loan Rate, Applicable
LIBOR Rate, and Non-Payment Rate. The Auction Agent shall calculate the
applicable Maximum Rate, Net Loan 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 applicable Maximum Rate, Net Loan 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 applicable Maximum
Rate, Net Loan Rate, Applicable 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 applicable Maximum Rate and the Net Loan 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 applicable
Maximum Rate, Net Loan 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 applicable Maximum
Rate, Net Loan 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 Payment Date to
     the beneficial owners of Auction Rate Notes.

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

                                      A-21

<PAGE>

               (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 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; and

               (B) 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 Payment Date to the beneficial
          owners of each Series of the Auction Rate Notes.

     If any day scheduled to be a 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 Payment Date or the old 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 by the holders of a majority of the aggregate principal amount
     of the Auction Rate Notes then Outstanding, and if by such Noteholders, by
     an instrument signed by such Noteholders 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

                                      A-22

     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 a Broker-Dealer Agreement with
     William R. Hough & Co., as the sole initial Broker-Dealer for Series A1-1
     Notes, Series A1-2 Notes, Series A1-3 Notes, Series A1-4 Notes, Series A1-5
     Notes, Series A1-6 Notes, Series A1-7 Notes, Series A1-8 Notes, Series A1-9
     Notes, Series A1-10 Notes, Series A1-11 Notes and Series B1-1 Notes and
     Series B1-2 Notes, and Salomon Smith Barney Inc., as the sole initial
     Broker-Dealer for Series A1-12 Notes and Series A1-13 Notes. An Authorized
     Officer may, from time to time, approve one or more additional persons to
     serve as a Broker-Dealer under the 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"), 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

                                      A-23

<PAGE>

     Indenture Trustee, the Auction Agent, the Market Agent, each 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
     nor more than 366 days.

          (iii) An Auction Period Adjustment shall take effect only if (A) the
     Indenture 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 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 Market Agent, with the written consent
of the Administrator on behalf of the Issuer, may specify a different 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 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 Administrator at least 14 days prior to the effective date
of such change. If the Administrator 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 Indenture Trustee, the Auction Agent, the Issuer, the Administrator,
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 an Auction Note Interest 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 Noteholders of
the Auction Rate Notes to which such Auction Note Interest 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 and are contracted for, charged, reserved, taken or received
pursuant to the Auction Rate Notes or related documents) calculated from the
Date of Issuance of the Series A Notes and the Series B Notes, as applicable,
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 Noteholder or any former Noteholder 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.
