Section 2.01. Series 2005-1 Note Details. The aggregate principal amount of the Series 2005-1 Notes which may be initially authenticated and delivered under this Supplemental Indenture is limited to, and shall be individually issued in four separate classes consisting of $140,000,000 of Class A-2L Notes, $235,000,000 of Class A-3L Notes, $100,000,000 of Class A-6AR Notes, and $25,000,000 of Class B Notes, except for Series 2005-1 Notes authenticated and delivered upon transfer of, or in exchange for, or in lieu of Notes pursuant to Sections 2.03 and 2.04 of the Indenture. The Series 2005-1 Notes shall be issuable only as fully registered notes in the Authorized Denominations. The Series 2005-1 Notes of each class shall each be lettered "R" and shall be numbered separately from 1 upwards, respectively. The Class A-2L Notes, the Class A-3L Notes and the Class A-6AR Notes constitute Senior Notes. The Class B Notes constitute Subordinate Notes. The Series 2005-1 Derivative Product Agreements constitute Senior Obligations.

The Class A-2L Notes, the Class A-3L Notes (collectively, the "LIBOR Rate Notes") shall be dated their Closing Date and shall bear interest from their Closing Date, payable on each Quarterly Distribution Date, except that LIBOR Rate Notes which are reissued upon transfer, exchange or other replacement shall bear interest from the most recent Quarterly Distribution Date to which interest has been paid, or if no interest has been paid, from the Closing Date. The Class A-2L Notes shall bear interest for each Interest Accrual Period, other than the first Interest Accrual Period, at a per annum rate equal to LIBOR, plus 0.03%. The interest rate on the Class A-2L Notes for the first Interest Accrual Period shall be 2.99%. The Class A-3L Notes shall bear interest for each Interest Accrual Period, other than the first Interest Accrual Period, at a per annum rate equal to LIBOR, plus 0.08%. The interest rate on the Class A-3L Notes for the first Interest Accrual Period shall be 3.04%. Interest payable on the LIBOR Rate Notes 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. The Class A-2L Notes shall mature, subject to Principal Reduction Payments, on August 25, 2014 (the Class A-2L Notes' "Stated Maturity"). The Class A-3L Notes shall mature, subject to Principal Reduction Payments, on November 25, 2020 (the Class A-3L Notes' "Stated Maturity").

The Class A-6AR Notes and Class B Notes (collectively, the "Auction Rate Securities") shall be dated their Closing Date and shall bear interest from their Closing Date, payable on each Payment Date (as defined in Appendix A to this Supplemental Indenture), except that Auction Rate Securities which are reissued upon transfer, exchange or other replacement shall bear interest from the most recent Payment Date to which interest has been paid, or if no interest has been paid, from the Closing Date. The Auction Rate Securities shall mature on March 25, 2042 (the Class A-6AR and Class B Notes' "Stated Maturity"). The terms of and definitions related to the Auction Rate Securities are found in Article I hereof and Appendix A to this Supplemental Indenture.

The principal of the Series 2005-1 Notes due at Stated Maturity or redemption in whole shall be payable at the Corporate Trust Office of the Indenture Trustee, or such other location as directed by the Indenture Trustee, or at the principal office of its successor in trust upon presentation and

surrender of the 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

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

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

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.

(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.

(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.

"Variable Rate" means the variable rate of interest per annum, including the Initial Rate, borne by each class of Auction Rate Securities during the Initial Period for such class, and each Interest Period thereafter as such rate of interest is determined in accordance with the provisions of Article II of this Appendix A.

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 have its beneficial ownership of the Auction Rate Securities maintained at all times in Book-entry Form for the account of its Participant, which in turn will maintain records of such beneficial ownership; and (iii) to authorize such Participant to disclose to the Auction Agent such information with respect to such beneficial ownership as the Auction Agent may request.

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

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

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

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

b. the principal amount of Outstanding Auction Rate 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;

b. 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)(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, if the Auction Note Interest Rate determined as provided in this Section 2.02(a) shall be equal to the rate specified in such Bid.

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

(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.

(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;

(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.

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.

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.

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 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.

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.
