4

 

surrender
of the Series 2005-1 Notes. Payment of interest and principal paid subject to a redemption on any Series 2005-1 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 Regular 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 Regular 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 Series 2005-1 Notes not less than 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
Series 2005-1 Notes, payments of interest shall, be paid by wire transfer within the United States to the bank account number filed no later than the Regular Record Date or Special
Record Date with the Indenture Trustee for such purpose. All payments on the Series 2005-1 Notes shall be made in lawful money of the United States of America. 

        (a)   Except
as otherwise provided in this Section, the Series 2005-1 Notes in the form of one global note for each Stated Maturity date shall be registered
in the name of the Securities Depository or its nominee and ownership thereof shall be maintained in book-entry form by the Securities Depository for the account of the Agent Members.
Initially, each Series 2005-1 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 2005-1 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." 

        (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 2005-1 Notes; (ii) the delivery to any Agent Member,
beneficial owner of the Series 2005-1 Notes or other Person, other than the Securities Depository, of any notice with respect to the Series 2005-1 Notes; or
(iii) the payment to any Agent Member, beneficial owner of the Series 2005-1 Notes or other Person, other than the Securities Depository, of any amount with respect to the
principal of or interest on the Series 2005-1 Notes. So long as the certificates for the Series 2005-1 Notes issued under this Supplemental Indenture are not
issued pursuant to paragraph (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 2005-1 Notes for all purposes whatsoever, including, without limitation, (A) the payment of principal of and interest on such
Series 2005-1 Notes, (B) giving notices of redemption and other matters with respect to such Series 2005-1 Notes, and (C) registering transfers with
respect to such Series 2005-1 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 

5

 

the
Securities Depository shall hold all of the Series 2005-1 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 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 2005-1 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, paragraphs (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 2005-1 Notes as provided below. In addition, the Issuer may determine at any time that the Series 2005-1 Notes shall no
longer be represented by global certificates and that the provisions of paragraphs (a) and (b) of this Section shall no longer apply to the Series 2005-1 Notes. In
such event, the Issuer shall execute and the Indenture Trustee shall authenticate and deliver certificates representing the Series 2005-1 Notes as provided below. Certificates for
the Series 2005-1 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 2005-1 Notes to the Persons in whose names
such Notes are so registered. 

        Section 2.02. Principal Reduction Payments and Redemptions of the Series 2005-1 Notes.    

        (a)   Mandatory Redemption of Auction Rate Securities. 

        (i)    Subject
to the provisions of Section 2.02(b) and (d)(ii) hereof and to the provisions of any future Supplemental Indenture, each class of the
Auction Rate Securities is subject to mandatory redemption, in whole or in part, at a redemption price equal to the principal balance being redeemed plus accrued interest to the date fixed for
redemption, on the first Payment Date occurring each month for such class of the Auction Rate Securities, from amounts remaining on deposit in the Redemption Account and not required to be used to
make Principal Reduction Payments or to redeem other Notes pursuant to any Supplemental Indenture. The Class A-1AR Notes through Class A-5AR Notes shall be
redeemed prior the redemption of Class A-6AR Notes, and the Class B-1AR Notes and the Class B-2AR Notes shall be redeemed prior the redemption
of Class B Notes. 

        (ii)   Notice of Redemption. The Indenture Trustee shall cause notice of any redemption pursuant to
Section 2.02(a)(i) hereof to be given by mailing a copy of the notice by first-class mail to the Administrator, the Auction Agent and the Noteholder of any Auction Rate Securities
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 15 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 Auction Rate Securities for which no such
failure or defect occurs. 

        (b)   Principal Reduction Payments on LIBOR Rate Notes. 

        (i)    Each
class of the LIBOR Rate Notes shall receive reductions of principal pursuant to Principal Reduction Payments to be made on Quarterly Distribution Dates from amounts
on deposit in the Redemption Account of the Acquisition Fund for such purpose in an amount 

6

 

up
to, but not greater than, the amount needed to reduce the outstanding balance of such class of the LIBOR Rate to its Targeted Balance set forth in Appendix B hereto for such Quarterly
Distribution Date. If any Principal Reduction Payments on the Class A-1L Notes, the Class A-2L Notes or the Class A-3L Notes are to be made on
the same Quarterly Distribution Dates, the Principal Reduction Payments will be made, first, on the Class A-1L Notes until the
Class A-1L Notes have been reduced to their Targeted Balance set forth in Appendix B to the Series 2003-2 Supplemental Indenture for such Quarterly
Distribution Date, second, on the Class A-2L Notes until the Class A-2L Notes have been reduced to their Targeted
Balance set forth in Appendix B hereto for such Quarterly Distribution Date and, third, on the Class A-3L Notes until the
Class A-3L Notes have been reduced to their Targeted Balance set forth in Appendix B hereto for such Quarterly Distribution Date. Preferably five, but not less than two
Business Days prior to each Quarterly Distribution Date, the Indenture Trustee shall send the Securities Depository written notice with respect to the dollar amount per $1,000 original principal
amount thereof, that the Indenture Trustee will be paying to the Securities Depository on the Quarterly Distribution Date for each class of the LIBOR Rate Notes. The Indenture Trustee may, to the
extent necessary to avoid payments of fractional cents, reduce scheduled payments by up to $1,000 for each class of the LIBOR Rate Notes. To the extent the Indenture Trustee effects any such
reduction, such amount shall be carried over to the next scheduled Principal Reduction Payment Date for that class of the LIBOR Rate Notes. Such notices, which shall clearly indicate that they relate
to a reduction of principal, shall contain the Ending Balance Factor and the Indenture Trustee contact's name and telephone number, shall be sent by facsimile (or such other method designated by the
Securities Depository) to the Securities Depository's Dividend Department. Failure to make a Principal Reduction Payment on a class of the LIBOR Rate Notes in the amount set
forth in the Targeted Amortization Schedule on the Principal Reduction Payment Date shall not constitute an Event of Default under the Indenture.

        (ii)   Notwithstanding
subsection (b)(i) of this Section or as provided in a subsequent Supplemental Indenture, if no Senior Notes (other than Senior
Notes subject to Principal Reduction Payments) remain outstanding, the LIBOR Rate Notes and any other Senior Notes subject to Principal Reduction Payments are subject to additional reductions of
principal pursuant to Principal Reduction Payments to be made on Quarterly Distribution Dates from any amounts remaining on deposit in the Redemption Account of the Acquisition Fund after making the
Principal Reduction Payments required pursuant to subsection (b)(i) of this Section. Any such amounts remaining on deposit in the Redemption Account of the Acquisition Fund shall be used
to further reduce the outstanding principal amount of any Senior Notes, which may include the LIBOR Rate Notes, subject to Principal Reduction Payments on the next succeeding Quarterly Distribution
Date to their Targeted Balances for such succeeding Quarterly Distribution Date. If the outstanding principal amount of all Senior Notes subject to Principal Reduction Payments on such succeeding
Quarterly Distribution Date have been reduced to their Targeted Balances for that succeeding Quarterly Distribution Date, then any such amounts remaining on deposit in the Redemption Account of the
Acquisition Fund shall be used to further reduce the outstanding principal amount of any Senior Notes, which may include the LIBOR Rate Notes, subject to Principal Reduction Payments on the next
succeeding Quarterly Distribution Date until they have been reduced to their Targeted Balances for such next succeeding Quarterly Distribution Date, and the Trustee shall continue this process until
the outstanding principal amount of all Senior Notes subject to Principal Reduction Payments have been reduced to zero. If any Principal Reduction Payments on the Class A-1L Notes,
the Class A-2L Notes or the Class A-3L Notes are to be made on the same Quarterly Distribution Dates, the Principal Reduction Payments will be made,  first, on the Class A-1L Notes until
the Class A-1L Notes have been reduced to their 

7

 

Targeted
Balance set forth in Appendix B to the Series 2003-2 Supplemental Indenture for such Quarterly Distribution Date,  second, on the Class A-2L Notes until the Class A-2L Notes have been
reduced to their Targeted Balance set forth
in Appendix B hereto for such Quarterly Distribution Date and, third, on the Class A-3L Notes until the
Class A-3L Notes have been reduced to their Targeted Balance set forth in Appendix B hereto for such Quarterly Distribution Date. 

        (iii)  Principal
Reduction Payments on the LIBOR Rate Notes will be made on a pro rata basis within each class of the LIBOR Rate Notes receiving Principal Reduction Payments
and subsequent to each Principal Reduction Payment, each LIBOR Rate Note will be outstanding in a fractional amount of its original principal amount. 

        (iv)  Notice of Principal Reduction. Preferably five, but not less than two Business Days prior to each Principal Reduction
Payment Date, the Indenture Trustee shall cause notice of any reduction pursuant to (i) or (ii) of this subsection (b) to be given by mailing a copy of the notice by first class
mail to the Administrator and Noteholder of any LIBOR Rate Notes designated for reduction in whole or in part, at their address as the same shall last appear upon the registration books on the
reduction date; provided, however, that failure to give such notice, or any defect therein, shall not affect the validity of any proceedings for the reduction of such LIBOR Rate Notes. 

        (c)   Optional Redemption or Purchase. 

        (i)    Optional Redemption or Purchase of Series 2005-1 Notes. Subject to the provisions of
Section 2.02(d) hereof, the Series 2005-1 Notes are subject to redemption or purchase at the option of the Issuer exercised by an Issuer Order, in whole only, on any
Payment Date on which the aggregate current principal balance of all the Notes issued under the Indenture is less than or equal to 10% of the initial aggregate principal balance of all the Notes
issued under the Indenture on their respective Closing Date, at a redemption price equal to (A) the principal balance plus accrued interest to the date fixed for redemption and (B) any
Carry-over Amount and any interest accrued on any Carry-over Amount to the date fixed for redemption, from the proceeds of funds received by the Indenture Trustee and deposited
in the Revenue Fund, the Acquisition Fund and the Reserve Fund. On the Payment Date fixed for redemption or purchase in such Issuer Order (which Issuer Order shall be received by the Indenture Trustee
not less then 16 days prior to such redemption), the Issuer shall deposit or cause to be deposited in or transferred to the Redemption Account of the Acquisition Fund (from the Revenue Fund) an
amount sufficient to redeem all of the Notes, less amounts on deposit in the Reserve Fund. On such redemption date the Indenture Trustee shall transfer amounts in the Reserve Fund to the Redemption
Account of the Acquisition Fund and effect the redemption of all the Notes. 

        (ii)   Notice of Redemption and Purchase. The Indenture Trustee shall cause notice of any redemption or purchase pursuant to
Section 2.02(c)(i) hereof to be given by mailing a copy of the notice by first-class mail to the Administrator, the Auction Agent, if applicable, and the Noteholder of any
Series 2005-1 Notes designated for redemption or purchase in whole or in part, at their address as the same shall last appear upon the registration books, in each case not less than
15 days prior to the redemption or purchase date; provided, however, that failure to give such notice, or any defect therein, shall not affect the validity of any proceedings for the redemption
or purchase of such Series 2005-1 Notes for which no such failure or defect occurs. 

8

 

        (d)   Partial Redemption. 

        (i)    If
less than all of the Auction Rate Securities are to be redeemed or purchased pursuant to Section 2.02(a)(i) hereof, the Auction Rate Securities to be
redeemed or purchased shall be redeemed or purchased on a monthly basis in ascending order of Stated Maturity and, within same Stated Maturities, from the Auction Rate Securities with the earliest
Payment Date during the month, subject to Section 2.02(d)(ii) hereof. If two or more classes of Auction Rate Securities have the same Stated Maturity and the same Payment Date, such
Auction Rate Securities shall be redeemed on a pro rata basis among or between such classes, subject to Section 2.02(d)(ii) hereof. 

        (ii)   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 Value of the Trust Estate to the Value of the Senior Notes and the Subordinate Notes then Outstanding exceeds 101.5% and the ratio of the Value of the Trust
Estate to the Value of the Senior Notes then Outstanding exceeds 104%, or such other percentages that satisfy the Rating Agency Condition, the Indenture Trustee shall redeem Class B Notes while
Class A Notes remain Outstanding until the Value of the Trust Estate to the Value of the Notes equals the percentages 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. 

        (iii)  If
less than all of a class of the Auction Rate Securities are to be redeemed, the Auction Rate Securities to be redeemed shall be selected by lot in such manner as
the Indenture Trustee shall determine. In the event of a redemption pursuant to Section 2.02(a)(i) hereof whereby funds remain in an amount below the Authorized Denomination, such
remaining funds shall be transferred to the Revenue Fund. 

        (iv)  In
case an Auction Rate Security is of a denomination larger than an Authorized Denomination, a portion of such Auction Rate Security (in an Authorized Denomination)
may be redeemed. Upon surrender of any Auction Rate Security 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 Auction Rate Security or Auction Rate Securities of the same series, maturity and of authorized denominations, in an aggregate principal amount
equal to the unredeemed portion of the Auction Rate Security surrendered.

        (c)   rating

Class B Notes have been rated "A" by Fitch and S&P and "A2" by Moody's and (iii) that the issuance of the Series 2005-1 Notes will not adversely affect the ratings
assigned to the Series 2003-1 Notes or the Series 2003-2 Notes or that the ratings on the Series 2003-1 Notes or the
Series 2003-2 Notes have been confirmed.

Series 2005-1 Notes shall be substantially in the forms provided in Exhibits A-1, A-2 and A-3 hereto. No Series 2005-1
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; and such certificate of the Indenture Trustee upon any Series 2005-1 Note shall be conclusive evidence and the only competent evidence
that such Note has been authenticated and delivered hereunder. The Indenture Trustee's certificate of authentication shall be deemed to have been duly executed by it if manually signed by an

hereunder. 

        Section 2.05. Deposit of Series 2005-1 Note Proceeds.    Upon the issuance and delivery of the

ARTICLE II

TERMS AND ISSUANCE  

        Section 2.01. Auction Rate and Carry-Over Amounts.    During the Initial Period, each class of Auction Rate
Securities shall bear interest at the Initial Rate for such class. Thereafter, and except with respect to an Auction Period Adjustment, the Auction Rate Securities shall bear interest at an Auction
Note Interest Rate based on a 28-day Auction Period for the Auction Rate Securities, as determined pursuant to this Section 2.01 and Section 2.02 of this
Appendix A. 

        For
the Auction Rate Securities during the Initial Period and each Auction Period thereafter, interest at the applicable Auction Rate Securities 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 and rounding the resultant figure to the fifth decimal place. 

        The
Auction Note Interest Rate to be borne by the Auction Rate Securities 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) 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 A-6AR Notes and (ii) 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 B Notes; provided, however, that in the case of the Auction Period that
immediately follows the Initial Period for the Auction Rate Securities, such Auction Period shall commence on the Initial Rate Adjustment Date. By way of example, if an Interest Period ordinarily
would end on a Wednesday, but the following Thursday is not a Business Day, the Interest Period will end on that Thursday and the new Interest Period will begin on Friday. The Auction
Note Interest Rate of the Auction Rate Securities for each Auction Period shall 

A-6

 

be
the Auction Rate in effect for such Auction Period as determined in accordance with Section 2.02(a) of this Appendix A. 

        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) 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 A-6AR Notes and
(ii) 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 B 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 Security is no longer maintained in Book-entry Form, the Auction Note Interest Rate on the Auction Rate Securities
for any Interest Period commencing after the delivery of certificates representing Auction Rate Securities 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 Securities 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 Securities. The Indenture Trustee shall, upon request, notify the Noteholders and the Issuer of Auction Rate Securities of the applicable
Auction Note Interest Rate applicable to such Auction Rate Securities for each Auction Period not later than the third Business Day of such Auction Period. Notwithstanding any other provision
of the Auction Rate Securities or this Supplemental Indenture and except for the occurrence of a Payment Default, interest payable on the Auction Rate Securities 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 Securities is greater than the Net Loan Rate, and the Net Loan Rate is less than the applicable Maximum Rate, the Issuer shall determine the
Carry-over Amount, if any, with respect to such Auction Rate Securities 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 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, 

A-7

 

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 Security by the Indenture Trustee 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 Indenture Trustee, the Indenture Trustee shall give written notice to each Noteholder the Auction Agent and the Issuer of the Carry-over Amount applicable to each Auction Rate
Security, which written notice may accompany the payment of 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 Security 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 (and interest accrued thereon) shall be paid with respect to any redeemed Auction Rate Security, (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 Security on the
earliest of (i) the date of defeasance of the Auction Rate Securities; or (ii) the first occurring Payment Date (or on the date of any 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 Securities shall be paid by the Indenture Trustee on Outstanding Auction Rate Securities on the earliest
of (a) the date of defeasance of any of the Auction Rate Securities; 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 Securities on such Payment Date, to redeem any Auction Rate Securities 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 Security which is due and payable on a Payment Date, which
Auction Rate Security 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) which is not yet due and payable on said Payment Date shall be cancelled with
respect to said Auction Rate Security 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 Securities; 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 Securities, the Indenture Trustee shall give written notice in the manner set forth in the immediately preceding
paragraph to the Noteholder of such Auction Rate Security receiving such partial payment of the Carry-over Amount remaining unpaid on such Auction Rate Security. 

        The
Payment Date or other date on which such Carry-over Amount (or any interest accrued thereon) for Auction Rate Securities shall be paid shall be determined by the
Indenture Trustee in 

A-8

 

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 Securities 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 Securities, 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 Securities 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. 

        In
the event the Indenture Trustee may be required to make any calculation in accordance with this Section, the Indenture Trustee may hire such calculation agents, experts, consultants
or agents as it deems necessary. 

        Section 2.02 Auction Rate.    

        (a)   Determining the Auction Rate. By purchasing Auction Rate Securities, whether in an Auction or otherwise, each purchaser
of the Auction Rate Securities, or its Broker-Dealer, must agree and shall be deemed by such purchase to have agreed (i) to participate in Auctions on the terms described herein, (ii) to

the Auction Note Interest Rate for the next succeeding Auction Period; 

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

        c.     the
principal amount of Outstanding Auction Rate Securities, if any, owned by such Existing Owner which such Existing Owner offers to sell without 

A-9

 

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 Securities which each Potential Owner offers to purchase, if
the Auction Note Interest Rate for the next succeeding Auction Period shall not be less than the rate per annum specified by such Potential Owner. 

        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 Securities 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;

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

        b.     such
principal amount, or a lesser principal amount of Outstanding Auction Rate Securities 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 Securities 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 Securities set forth in Section 2.02(a)(iv)(A)(5) of this Appendix A,

A-10

 

        (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 Securities 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 Securities, if any, subject to any Hold Order placed by such Existing Owner; 

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

        (4)   to

        (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 .001%. 

        (C)  If
an Order or Orders covering all Outstanding Auction Rate Securities 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 Securities 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 Securities 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 Securities owned by such Existing Owner, and if the
aggregate principal amount of Auction Rate Securities subject to such Hold Orders exceeds the aggregate principal amount of Auction Rate Securities owned by such Existing Owner, the aggregate
principal amount of Auction Rate Securities subject to each such Hold Order shall be reduced pro rata so that the aggregate principal amount of Auction Rate Securities subject to such Hold Order
equals the aggregate principal amount of Outstanding Auction Rate Securities 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 Securities owned by such
Existing Owner over the aggregate principal amount of Auction Rate Securities subject to any Hold Order referred to in clause (A) of this paragraph (ii); 

A-11

  

        b.     subject
to subclause (1) 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 Securities subject to such Bids is greater than such excess, such Bids shall be considered valid up to an amount equal to such excess; 

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

        d.     in
any such event, the amount of Outstanding Auction Rate Securities, 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 Securities owned by such Existing Owner
over the aggregate principal amount of Auction Rate Securities subject to Hold Orders referred to in clause (1) of this paragraph (v) and valid Bids referred to in
clause (2) of this paragraph (E). 

        (F)  If
more than one Bid for Auction Rate Securities 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 Securities 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 Securities 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 Securities 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 Securities over the sum of the aggregate principal amount of Outstanding Auction Rate Securities
subject to Submitted Hold Orders (such excess being herein referred to as the "Available Auction Rate Securities"), and 

A-12

 

        (2)   from
the Submitted Orders whether: 

        a.     the
aggregate principal amount of Outstanding Auction Rate Securities 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 Securities 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 Securities subject to Submitted Sell Orders; 

        (in
the event such excess or such equality exists, other than because all of the Outstanding Auction Rate Securities 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 Securities 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 Securities which, when added to the
aggregate principal amount of Outstanding Auction Rate Securities to be purchased by such Potential Owners described in subclause b. above, would equal not less than the Available Auction Rate
Securities. 

        (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. The Indenture Trustee may conclusively rely on the
Auction Agent with respect to receipt or non-receipt of such rates described above without duty to know, determine or further examine. 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 Securities 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 

A-13

 

        (3)   if
all Outstanding Auction Rate Securities 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 least of (x) the Auction Rate, (y) the Net Loan Rate and (z) the applicable Maximum Rate. 

        (iv)  Existing
Owners shall continue to own the principal amount of Auction Rate Securities that are subject to Submitted Hold Orders. If the Cap 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 Net Loan Rate is less than the Auction Rate, the Net Loan Rate will be the Auction Note Interest Rate unless the Auction Rate and the Net Loan Rate are both greater than
the applicable Maximum Rate, in which event the Auction Note Interest Rate shall be equal to the Maximum Rate. If the Auction Agent has not received Sufficient Bids (other than because all of the
Outstanding Auction Rate Securities are subject to Submitted Hold Orders), the Auction Note Interest Rate will be the lesser of the Net Loan Rate and 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: 

        (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 Securities 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 Securities 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 Securities subject to such Submitted Bid, unless the aggregate principal amount of Outstanding Auction Rate Securities subject to all
such Submitted Bids shall be greater than the principal amount of Auction Rate Securities (the "remaining principal amount") equal to the excess of the Available Auction Rate Securities over the
aggregate principal amount of Auction Rate Securities 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 

A-14

 

Owner
shall be rejected in part, and such Existing Owner shall be entitled to continue to own the principal amount of Auction Rate Securities subject to such Submitted Bid, but only in an amount equal
to the aggregate principal amount of Auction Rate Securities obtained by multiplying the remaining principal amount by a fraction, the numerator of which shall be the principal amount of Outstanding
Auction Rate Securities 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 Securities 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 Securities obtained by multiplying the excess of the aggregate principal amount of Available Auction Rate Securities over the aggregate principal amount of Auction
Rate Securities 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 Securities subject to such Submitted Bid and the denominator of which shall be the sum of the principal amount of Outstanding Auction Rate Securities
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 Securities 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 Securities 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 Securities 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 Securities obtained by multiplying the aggregate principal amount of Auction Rate Securities 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 Securities owned by such Existing Owner subject to such submitted Bid or Submitted Sell Order and the denominator of which shall be the aggregate 

A-15

 

principal
amount of Outstanding Auction Rate Securities subject to all such Submitted Bids and Submitted Sell Orders. 

        (C)  If
all Auction Rate Securities 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 Securities 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 Securities to be purchased or sold by any Existing Owner or Potential Owner so
that the principal amount of Auction Rate Securities 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 Securities, the Auction Agent shall, in such manner as in its sole discretion it shall determine, allocate Auction Rate Securities for
purchase among Potential Owners so that only Auction Rate Securities 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 Securities. 

        (v)   Based
on the result of each Auction, the Auction Agent shall determine the aggregate principal amount of Auction Rate Securities to be purchased and the aggregate
principal amount of Auction Rate Securities 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 Securities to be sold differs from such aggregate
principal amount of Auction Rate Securities 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 Securities. 

        (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. In the event the Indenture Trustee may be required to make any calculation in accordance with the
provisions of this Section 2.02(a)(vi) the Indenture Trustee may hire such calculation agents, experts, consultants or agents as it deems necessary. 

        (vii) Notwithstanding
anything in this Appendix A to the contrary, (A) no Auction for the Auction Rate Securities 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 Securities 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 Securities. 

        (i)    The
Indenture Trustee shall determine not later than 2:00 p.m., eastern time, on the Business Day next succeeding Payment Date, whether a Payment Default has
occurred. If a 

A-16

 

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)   The
Indenture Trustee shall pay to the Auction Agent, in immediately available funds out of amounts in the Operating 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 Operating 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 Operating 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 Securities 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 LIBOR Rate, All Hold Rate and Non-Payment Rate
for each such Interest Period. If the ownership of the Auction Rate Securities 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 Securities 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. In the event the Indenture Trustee may be required to make any calculation in accordance with the provisions of this Section 2.02(c), the Indenture Trustee may
hire such calculation agents, experts, consultants or agents as it deems necessary and shall be reimbursed by the Issuer for any costs or expenses associated with such hiring. 

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

        (i)    By
12:00 p.m., 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 Securities. 

        (ii)   At
least four days prior to any 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 Securities 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; 

A-17

 

        (B)  pursuant
to Section 2.01 of this Appendix A, advise the Registered Owners of a class of Auction Rate Securities of any Carry-over Amount
accruing on such Auction Rate Securities; and 

        (C)  advise
the Securities Depository, so long as the ownership of the Auction Rate Securities 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 class of the Auction Rate Securities. 

        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
Securities 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 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 of the Issuer or
by the holders of a majority of the aggregate principal amount of the Auction Rate Securities 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 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 of the Issuer, shall use its best
efforts to appoint a Substitute Auction Agent. 

A-18

 

        (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-Dealer. 

        (i)    The
Auction Agent will enter into Broker-Dealer Agreement with Citigroup Global Markets, Inc. as the initial Broker-Dealer. 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 Securities are Outstanding, the applicable Broker-Dealer, with the written consent of an Authorized Officer, 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 Securities. The Broker-Dealer shall initiate the Auction Period
Adjustment by giving written notice to the Indenture Trustee, the Administrator, the Auction Agent, each Rating Agency and the Securities Depository in substantially the form of, or containing
substantially the information contained in, Exhibit E attached hereto at least 10 days prior to the Auction Date for such Auction Period. 

        (ii)   Any
such adjusted Auction Period shall not be less than seven days nor more than 270 days. Any adjusted Auction Period of more than 120 days may
not be initiated without a Rating Confirmation. 

        (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, notice from the applicable Broker-Dealer 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; and (B) Sufficient Bids exist as of the Auction on the Auction Date for
such first Auction Period. If the condition referred to in clause (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
clause (A) above is met but the condition referred in clause (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 2.05(a) 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 

A-19

 

below,
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 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
Securities. 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. Notwithstanding
the foregoing, the applicable Broker-Dealer may, without consent from an Authorized Officer, an opinion of Note Counsel, request for consent or notice to the Indenture Trustee, the Auction
Agent, the Issuer, any Rating Agency or the Securities Depository, (i) defer any Auction Date to the next succeeding Business Day, if the Auction Date would, without such deferral, not be a
Business Day; and (ii) in such event, shorten the next succeeding Auction period by the number of days that the prior Auction Date was deferred. 

        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 2.05(b) of the Auction Agent Agreement. 

        Section 2.03. Additional Provisions Regarding the Interest Rates on the Auction Rate Securities.    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 Noteholders of the
Auction Rate Securities 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 Securities (including interest calculated as provided herein, plus any other amounts that
constitute interest on the Auction Rate Securities under applicable law, which are contracted for, charged, reserved, taken or received pursuant to the Auction Rate Securities or related documents)
calculated from the Date of Closing of the Auction Rate Securities through any subsequent day during the term of the Auction Rate Securities or otherwise prior to payment in full of the Auction Rate
Securities 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 Securities or
related documents or otherwise contracted for, charged, reserved, taken or received in connection with the Auction Rate Securities, or if the redemption or acceleration of the maturity of the Auction
Rate Securities results in payment to or receipt by the Noteholder or any former Noteholder of the Auction Rate Securities of any interest in excess of that permitted by applicable law, then,
notwithstanding any provision of the Auction Rate
Securities or related documents to the contrary, all excess amounts theretofore paid or received with respect to the Auction Rate Securities shall be credited on the principal balance of the Auction
Rate Securities (or, if the Auction Rate Securities have been paid or would thereby be paid in full, refunded by the recipient thereof), and the provisions of the Auction Rate Securities 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 Securities and under the related documents.

any successor indenture trustee under the Indenture) and Zions First National Bank, as Eligible Lender Trustee, the Series 2003-1 Supplemental Indenture of Trust dated as of

above) or registered assigns, the Principal Sum of (stated above), but solely from the revenues and receipts hereinafter specified and not otherwise, on the Maturity Date specified above (subject to
the right of prior redemption hereinafter described), upon presentation and surrender of this note at the Corporate Trust Office of the Indenture Trustee, as paying agent, Indenture Trustee,
authenticating agent and registrar for the Notes, or a duly appointed successor paying agent, and to pay interest in arrears on said Principal Sum, but solely from the 

A-1-1

 

revenues
and receipts hereinafter specified and not otherwise, to the Noteholder hereof from the most recent Payment Date to which interest has been paid hereon, until the payment of said principal
sum in full. 

        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 a LIBOR rate, as determined in the Series 2005-1 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 and rounding the resultant figure to the fifth
decimal place. 

        This
note is one of a series of notes of the Issuer designated GCO ELF Student Loan Asset-Backed Notes, [Senior Class A-2L LIBOR Floating
Rate,] [Senior Class A-3L LIBOR Floating Rate] dated the Closing Date, in the aggregate original principal amount of $            (the
"Class A-[2L][3L] Notes") which have been authorized by the Issuer, and issued by the Issuer pursuant to the Indenture. The Issuer
is, simultaneously with the Class A-[2L][3L] Notes, issuing $            of its GCO ELF Student Loan Asset-Backed Notes, Senior
Class A Notes in two other classes (together with the Class A-[2L][3L] Notes, the "Class A Notes") and $25,000,000 of
its GCO ELF Student Loan Asset-Backed Notes, Subordinate Class B-3AR Auction Rate Securities in one class (the "Class B 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 and the Class B Notes as determined by the Issuer. The Issuer has previously issued $206,000,000 of its GCO ELF Student Loan Asset-Backed Notes, Senior Class A Notes
and $14,000,000 of its GCO ELF Student Loan Asset-Backed Notes, Subordinate Class B Notes (collectively, the "Series 2003-1 Notes") and $192,000,000 of its GCO ELF Student
Loan Asset-Backed Notes, Senior Class A Notes and $8,000,000 of its GCO ELF Student Loan Asset-Backed Notes, Subordinate Class B Notes (collectively, the
"Series 2003-2 Notes"). The Series 2003-1 Notes, the Series 2003-2 Notes, the Class A Notes, the Class B Notes and any Additional
Notes are collectively referred to herein as the "Notes." 

        Principal Reduction Payments.    This note shall receive reductions of principal pursuant to Principal
Reduction Payments to be made on Quarterly Distribution Dates from amounts on deposit in the Redemption Account of the Acquisition Fund for such purpose in an amount up to, but not greater than, the
amount needed to reduce the outstanding balance of the Class A-[2L][3L] to its Targeted Balance set forth in Appendix B to the
Series 2005-1 Supplemental Indenture for such Quarterly Distribution Date as provided in the Series 2005-1 Supplemental Indenture. 

        In
addition, if no Senior Notes (other than Senior Notes subject to Principal Reduction Payments) remain outstanding, this note is subject to additional reductions of principal pursuant
to Principal Reduction Payments to be made on Quarterly Distribution Dates from any amounts remaining on deposit in the Redemption Account of the Acquisition Fund as provided in the
Series 2005-1 Supplemental Indenture. 

A-1-2

 

        Notice of Principal Reduction.    The Indenture Trustee shall cause notice of the payment of Principal
Reduction Payments on this note to be given to the Noteholder hereof not less than two Business Days prior to each Principal Reduction Payment Date. 

        Optional Redemption or Purchase.    The Issuer may redeem or purchase or cause to be purchased all of
the Notes on any Payment Date on which the aggregate current principal balance of all the Notes shall be less than or equal to 10% of the initial aggregate principal balance of all the Notes issued
under the Indenture on the respective Closing Date, at a redemption or purchase price equal to the aggregate current principal balance of all the Notes, plus accrued interest on the Notes through the
day preceding the Payment Date on which the redemption or purchase occurs. 

        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 15 days prior to the redemption or purchase date to the Noteholders to be redeemed in whole or in part at the address of such Noteholder 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 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. 

        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 Notes. 

        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 in the Corporate Trust Office of the Indenture Trustee, and to all of the provisions of which any Noteholder 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 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 Noteholders and any Reciprocal Payor; the rights and remedies of the Noteholder hereof with respect hereto and thereto,
including the limitations upon the
right of a Noteholder 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. 

A-1-3

 

        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, the Delaware Trustee, or any incorporator, director, officer, employee, or agent of the Issuer, nor against the State of Delaware, 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. 

        Subject
to the restrictions specified in the Indenture, this note is transferable on the Note Register kept for that purpose by the Indenture Trustee, as registrar, upon surrender
of this note for transfer at the 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 Noteholder 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 Noteholder, any Note may be exchanged for
other Notes in authorized denominations upon surrender of the Note to be exchanged at the Corporate Trust Office of the Indenture Trustee. Upon any such presentation for exchange, one or more
new Notes of the same series, Stated Maturity, in authorized denominations, bearing interest at the same rate, and for the same aggregate principal amount as the Note or Notes so surrendered
will be issued to the Noteholder of the Note or Notes so surrendered; and the Note or Notes so surrendered shall thereupon be cancelled by the Indenture Trustee. Except as otherwise
permitted in the Indenture, this global note may be transferred in whole but not in part only to the Securities Depository or a nominee thereof, as defined in the Indenture, 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 Noteholder hereof (a) on the record date for
purposes of receiving timely payment of interest hereon; (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 holders of the
Notes then Outstanding or without the consent of any of such Noteholders (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, Payment Date, or rate of interest on any Outstanding Notes or affect the rights of the Noteholders of less than all of the Notes
Outstanding. 

        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 Delaware to happen, exist, and be performed precedent to and in the issuance of this
note, and the execution of said Indenture, have happened, exist and have been performed as so required.

previously issued $206,000,000 of its GCO ELF Student Loan Asset-Backed Notes, Senior Class A Notes and $14,000,000 of its GCO ELF Student Loan Asset-Backed Notes, Subordinate Class B
Notes (collectively, the "Series 2003-1 Notes") and $192,000,000 of its GCO ELF Student Loan Asset-Backed Notes, Senior Class A Notes and $8,000,000 of its GCO ELF Student
Loan Asset-Backed Notes, Subordinate Class B Notes (collectively, the "Series 2003-2 Notes"). The Series 2003-1 Notes, the Series 2003-2
Notes, the Class A Notes, the Class B Notes and any Additional Notes are collectively referred to herein as the "Notes." 

        Mandatory Redemption.    This note is subject to mandatory redemption, in whole or in part, at a
redemption price equal to the principal balance being redeemed plus accrued interest to the date fixed for redemption, on the first Payment Date occurring each month for this note, from amounts
remaining on deposit in the Redemption Account as provided in the Series 2005-1 Supplemental Indenture. 

        Optional Redemption or Purchase.    The Issuer may redeem or purchase or cause to be purchased all of
the Notes on any Payment Date on which the aggregate current principal balance of all the Notes shall be less than or equal to 10% of the initial aggregate principal balance of all the Notes issued
under the Indenture on the respective Closing Date, at a redemption or purchase price equal to the aggregate current principal balance of all the Notes, plus accrued interest on the Notes through the
day preceding the Payment Date on which the redemption or purchase occurs. 

        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 15 days prior to the redemption or purchase date to the Noteholders to be redeemed in whole or in part at the address of such Noteholder 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 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 

A-2-2

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 Notes. 

        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 in the Corporate Trust Office of the Indenture Trustee, and to all of the provisions of which any Noteholder 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 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

other terms and provisions thereof.

against the Indenture Trustee, the Delaware Trustee, or any incorporator, director, officer, employee, or agent of the Issuer, nor against the State of Delaware, 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. 

        Subject
