     SECTION 2.01. SERIES 2003-1 NOTE DETAILS. The aggregate principal amount of
the Series 2003-1 Notes which may be initially authenticated and delivered under
this Supplemental Indenture is limited to, and shall be individually issued in
five separate classes consisting of $78,000,000 of Class A-1AR Notes,

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 2003-1 Notes shall be
issuable only as fully registered notes in the Authorized Denominations. The
Series 2003-1 Notes of each class shall each be lettered "R" and shall be
numbered separately from 1 upwards, respectively. The Class A-1AR Notes, the
Class A-2AR Notes and the Class A-3AR Notes constitute Senior Notes. The Class B
Notes constitute Subordinate Notes. The Series 2003-1 Derivative Product
Agreements constitute Senior Obligations.

     The Class A 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 June 1, 2040 (a "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 2003-1 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 2003-1 Notes. Payment of interest and principal paid
subject to a redemption on any Series 2003-1 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 Record Date
for such Payment Date, but any such interest not so timely paid or duly provided
for shall cease to be payable to the Noteholder thereof at the close of business
on the Record Date and shall be payable to the Noteholder thereof at the close
of business on a special record date (a "Special Record Date") for the payment
of any such defaulted interest. Such Special Record Date shall be fixed by the
Indenture Trustee whenever moneys become available for payment of the defaulted
interest, and notice of such Special Record Date shall be given to the
Noteholders of the Series 2003-1 Notes not less than 10 days prior thereto by

                                        3
<Page>

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
2003-1 Notes, payments of interest shall, be paid by wire transfer within the
United States to the bank account number filed no later than the Record Date or
Special Record Date with the Indenture Trustee for such purpose. All payments on
the Series 2003-1 Notes shall be made in lawful money of the United States of
America.

          (a)  Except as otherwise provided in this Section, the Series 2003-1
     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
     2003-1 Note shall be registered in the name of CEDE & CO., as the nominee
     of The Depository Trust Company. Except as provided in subsection (d) of
     this Section, the Series 2003-1 Notes may be transferred, in whole but not
     in part, only to the Securities Depository or a nominee of the Securities
     Depository or to a successor Securities Depository selected or approved by
     the Issuer or to a nominee of such successor Securities Depository. Each
     global note shall bear a legend substantially to the following effect:
     "Except as otherwise provided in the Indenture, this global note may be
     transferred, in whole but not in part, only to another nominee of the
     Securities Depository, as defined in the Indenture, or to a successor
     Securities Depository or to a nominee of a successor Securities
     Depository."

          (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 2003-1
     Notes; (ii) the delivery to any Agent Member, beneficial owner of the
     Series 2003-1 Notes or other Person, other than the Securities Depository,
     of any notice with respect to the Series 2003-1 Notes; or (iii) the payment
     to any Agent Member, beneficial owner of the Series 2003-1 Notes or other
     Person, other than the Securities Depository, of any amount with respect to
     the principal of or interest on the Series 2003-1 Notes. So long as the
     certificates for the Series 2003-1 Notes issued under this Supplemental
     Indenture are not issued pursuant to 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
     2003-1 Notes for all purposes whatsoever, including, without limitation,
     (A) the payment of principal of and interest on such Series 2003-1 Notes,
     (B) giving notices of redemption and other matters with respect to such
     Series 2003-1 Notes, and (C) registering transfers with respect to such
     Series 2003-1 Notes. In connection with any notice or other communication
     to be provided to the 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
     2003-1 Notes, give the Securities Depository notice of such record date not
     less than 15 calendar days in advance of such record date to the extent
     possible. Such

                                        4
<Page>

     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 2003-1 Notes
     or if at any time the Securities Depository shall no longer be registered
     or in good standing under the Securities Exchange Act or other applicable
     statute or regulation and a successor Securities Depository is not
     appointed by the Issuer within 90 days after the Issuer receives notice or
     becomes aware of such condition, as the case may be, 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 2003-1 Notes as provided below. In addition, the
     Issuer may determine at any time that the Series 2003-1 Notes shall no
     longer be represented by global certificates and that the provisions of
     paragraphs (a) and (b) of this Section shall no longer apply to the Series
     2003-1 Notes. In such event, the Issuer shall execute and the Indenture
     Trustee shall authenticate and deliver certificates representing the Series
     2003-1 Notes as provided below. Certificates for the Series 2003-1 Notes
     issued in exchange for a global certificate pursuant to this subsection
     shall be registered in such names and authorized denominations as the
     Securities Depository, pursuant to instructions from the Agent Members or
     otherwise, shall instruct in writing to the Issuer and the Indenture
     Trustee, and upon which written instructions the Indenture Trustee may rely
     without investigation. The Indenture Trustee shall promptly deliver such
     certificates representing the Series 2003-1 Notes to the Persons in whose
     names such Notes are so registered.

     SECTION 2.02. REDEMPTION OF THE SERIES 2003-1 NOTES.

          (a)  MANDATORY REDEMPTION. Subject to the provisions of Section
     2.02(c), the Series 2003-1 Notes are 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 (i)
     on the first Interest Payment Date after October 15, 2003 from amounts
     remaining on deposit in the 2003-1 Acquisition Account on October 1, 2003
     representing proceeds of the Series 2003-1 Notes not used to acquire
     Student Loans, (ii) unless otherwise directed in a Supplemental Indenture,
     on the first Payment Date occurring each month for the Senior Notes
     (subject to Section 2.02(c)(ii)) from amounts remaining on deposit in the
     2003-1 Acquisition Account representing Recoveries of Principal and (iii)
     on the first Payment Date occurring each month for the Senior Notes
     (subject to Section 2.02(c)(ii))that the Value of the Trust Estate is less

     Outstanding and 104% of the Value of the Senior Notes then Outstanding as
     certified to the Indenture Trustee in an Issuer Order upon which Issuer
     Order the Indenture Trustee may conclusively rely (or such other ratio as
     specified by the Issuer in a notice to the Indenture Trustee accompanied by
     a Rating Agency Confirmation), from moneys on deposit in the Revenue Fund
     after all other required payments have been made and amounts transferred
     pursuant to Section 3.02 until such percentages are reached.

          (b)  OPTIONAL REDEMPTION OR PURCHASE.

               (i)     OPTIONAL REDEMPTION OR PURCHASE OF SERIES 2003-1 NOTES.
          Subject to the provisions of Section 2.02(c), the Series 2003-1 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
          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 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(b)(i) to be given by mailing a copy of the notice by first-class
          mail to the Noteholder of any Series 2003-1 Notes, the Administrator,
          the Calculation Agent and the Auction Agent, designated for redemption
          or purchase in whole or in part, at their address as the same shall
          last appear upon the registration books, in each case not less than 15
          days prior to the redemption or purchase date; provided, however, that
          failure to give such notice, or any defect therein, shall not affect
          the validity of any proceedings for the redemption or purchase date of
          such Series 2003-1 Notes for which no such failure or defect occurs.

          (c)  PARTIAL REDEMPTION.

               (i)     If less than all of the Series 2003-1 Notes are to be
          redeemed or purchased pursuant to Section 2.02(a), the Class of Series
          2003-1 Notes to be redeemed or purchased shall be redeemed or
          purchased on a monthly basis in ascending order of Stated Maturity

                               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. Each such Auction
Period after the Initial Period shall commence on and include the Business Day
following the expiration of the immediately preceding Auction Period and
terminate on and include the (i) second Business Day of the following fourth
week in the case of the Class A-1AR Notes, Class A-2AR Notes and the Class B

that immediately follows the Initial Period for the Auction Rate Securities,
such Auction Period shall commence on the Initial Rate Adjustment Date. The
Auction Note Interest Rate of the Auction Rate Securities for each Auction
Period shall be the Auction Rate in effect for such Auction Period as determined
in accordance with Section 2.02(a) of this Appendix A; provided that if, on any
Interest Rate Determination Date, an Auction is not held for any reason, then
the Auction Note Interest Rate on such Auction Rate Securities for the next
succeeding Auction Period shall be the applicable Cap Rate.

     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

                                       A-8
<Page>

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 Issuer, provided the Indenture Trustee has
received notice of One-Month LIBOR from the Issuer, and if the Indenture Trustee
shall not have received such notice from the Issuer, 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, 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
Issuer during such Interest Period in sufficient time for the Indenture Trustee
to give notice to each Noteholder of such Carry-over Amount as required in the
next succeeding sentence. Not less than four days before the Payment Date for an
Interest Period with respect to which such Carry-over Amount has been calculated
by the Issuer, the Indenture Trustee shall give written notice to each
Noteholder the Auction Agent and the Issuer, in the form provided by the Issuer,
of the Carry-over Amount applicable to each Auction Rate 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 all accrued Carry-over Amounts (and all
accrued interest thereon) that remains unpaid shall be canceled and no
Carry-over Amount (and interest accrued thereon) shall be paid with respect to
such Auction Rate 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 pursuant to an Issuer Order 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 with respect to the Auction Rate Security (or
on the date of any such optional redemption) if and to the extent that (A) the
Eligible Carry-over Make-Up Amount with respect to such subsequent Interest
Period is greater than zero; and (B) moneys are available pursuant to the terms
of the Indenture in an amount sufficient to pay all or a portion of such
Carry-over Amount (and interest accrued thereon); and (b) interest shall accrue
on the Carry-over Amount at a rate equal to One-Month LIBOR until such
Carry-over Amount is paid in full or is cancelled.

                                       A-9
<Page>

     The Carry-over Amount (and interest accrued thereon) for Auction Rate
Securities shall be paid by the Indenture Trustee pursuant to an Issuer Order 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 an
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 by the
Indenture Trustee, shall be determined in accordance with the provisions of the
immediately preceding paragraph, and the Indenture Trustee shall make payment of
the Carry-over Amount (and any interest accrued thereon) in the same manner as,
and from the same Fund from which, it pays interest on the Auction Rate
Securities on an 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.

                                      A-10

     In the event the Indenture Trustee may be required to make any calculation
in accordance with this Section 2.01, the 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;

                       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

                            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 regard to the Auction Note Interest Rate for
                            the next succeeding Auction Period; and

<Page>

                            (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

                            be equal to the rate specified in such Bid.

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

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

                            (2)  the aggregate principal amount of Auction Rate
                       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.

<Page>

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

                                 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

                                      A-14
<Page>

                            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

                            (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

                                      A-16
<Page>

                            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 Net Loan Rate, Maximum
               Rate and the All Hold Rate and the components thereof on the
               Auction Date provided, however, the Auction Agent shall have no
               obligation to determine the Net Loan Rate except on any Auction
               Date on which Sufficient Bids do not exist for such 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

                            (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

                                      A-17
<Page>

               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 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

                                      A-19

                            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 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

                                      A-20
<Page>

                       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, the Net Loan 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
               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.

<Page>

                       (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, NET LOAN
          RATE, APPLICABLE LIBOR RATE, AND NON-PAYMENT RATE. The Auction Agent
          shall calculate the applicable Maximum Rate, Net Loan Rate, Applicable
          LIBOR Rate, and All Hold Rate, as the case may be, on each Auction
          Date and shall notify the Indenture Trustee and the Broker-Dealers of
          the applicable Maximum Rate, Net Loan Rate, Applicable LIBOR Rate, and
          All Hold Rate, as the case may be, as provided in the Auction Agent
          Agreement; provided, that if the ownership of the Auction Rate
          Securities is no longer maintained in Book-entry Form, or if a Payment
          Default has occurred, then the Indenture Trustee shall determine the
          applicable Maximum Rate, Net Loan Rate, Applicable LIBOR Rate, All
          Hold Rate and Non-Payment Rate for each such Interest Period. If the
          ownership of the Auction Rate Securities is no longer maintained in
          Book-entry Form by the Securities Depository, the Indenture Trustee
          shall calculate the applicable Maximum Rate and the Net Loan Rate on
          the Business Day immediately preceding the first day of each Interest
          Period after the delivery of certificates representing the Auction
          Rate 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 applicable Maximum Rate, Net Loan Rate, Applicable
          LIBOR Rate, All Hold Rate and Non-Payment Rate shall (in the absence
          of manifest error) be final and binding upon all parties. If
          calculated or determined by the Auction Agent, the Auction Agent shall
          promptly advise the Indenture Trustee of the applicable Maximum Rate,
          Net Loan Rate, Applicable LIBOR Rate, and All Hold Rate. 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.

               (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

                                      A-22
<Page>

               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; and

                            (B)  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 an 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.

                                      A-23
<Page>

          The Auction Agent may be removed at any time by the Indenture Trustee
          upon the written direction of an Authorized Officer or by the holders
          of a majority of the aggregate principal amount of the Auction Rate
          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, shall use its best efforts to appoint a Substitute Auction
          Agent.

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

          (f)  BROKER-DEALER.

               (i)     The Auction Agent will enter into Broker-Dealer
          Agreements with Salomon Smith Barney Inc. and GMAC Commercial Holdings
          Capital Markets Corp. as the initial Broker-Dealers. 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.

                                      A-24

          (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 (A) above is not met, the applicable Auction Note Interest Rate
          for the next Auction Period shall be determined pursuant to the above
          provisions of this Section 2.02 and the Auction Period shall be the
          Auction Period determined without reference to the proposed change. If
          the condition referred to in (A) is met but the condition referred in
          (B) above is not met, the applicable Auction Note Interest Rate for
          the next Auction Period shall be the applicable Maximum Rate and the
          Auction Period shall be the Auction Period determined without
          reference to the proposed change.

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

          (h)  CHANGES IN THE AUCTION DATE. The applicable Broker-Dealer, with
     the written consent of an Authorized Officer and, if applicable, upon
     receipt of the opinion of Note Counsel as required below, may specify 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

                                      A-25
<Page>

     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 2.03 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

                                      A-26
<Page>

recovery of the fullest amount otherwise called for under the Auction Rate
Securities and under the related documents.

PRINCIPAL SUM: _______________________________________________AND 00/100 DOLLARS
NOTEHOLDER: CEDE & CO.

     GMAC EDUCATION LOAN FUNDING TRUST-I, a Delaware statutory trust organized
under the laws of the State of Delaware (the "Issuer," which term includes any
successor entity under the Indenture of Trust, dated as of March 1, 2003 (the
"Indenture") and the Series 2003-1 Supplemental Indenture of Trust dated as of
March 1, 2003 (as amended, the "Series 2003-1 Supplemental Indenture"), each
between the Issuer and Zions First National Bank, as Indenture Trustee (the
"Indenture Trustee," which term includes any successor indenture trustee under
the Indenture)) for value received, hereby promises to pay to the Noteholder
(stated above) or

<Page>

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 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 an Auction Rate, all as determined in
Appendix A of the Series 2003-1 Supplemental Indenture.

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

     Interest payable on this note shall be computed on the assumption that each
year contains 360 days and actual days elapsed and rounding the resultant figure
to the fifth decimal place.

     This note is one of a series of notes of the Issuer designated GMAC ELF
Student Loan Asset-Backed Notes, Senior Class A-[1AR][2AR][3AR] Auction Rate
Securities, dated the Closing Date, in the aggregate original principal amount
of $__________ (the "Class A-[1AR][2AR][3AR] 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-[1AR][2AR][3AR] Notes, issuing $__________
of its GMAC ELF Student Loan Asset-Backed Notes, Senior Class A Notes in two
other classes (together with the Class A-[1AR][2AR][3AR] Notes, the "Class A
Notes") and $14,000,000 of its GMAC ELF Student Loan Asset-Backed Notes,
Subordinate Class B-1AR 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 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, all as
described in the 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

                                      A-1-2
<Page>

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
Auction Rate Securities for which no such failure or defect occurs. All Notes
called for redemption or purchase will cease to bear interest after the
specified redemption or purchase date, provided funds for their payment are on
deposit at the place of payment at the time. If less than all Notes are to be
redeemed or purchased, Notes shall be selected for redemption or purchase as
provided in the Indenture.

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

                                      A-1-3
<Page>

longer be secured by the Indenture or be deemed to be Outstanding, as defined in
the Indenture, thereunder; and for the other terms and provisions thereof.

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

     No recourse, either directly or indirectly, shall be had for the payment of
the principal of and interest on this note or any claim based hereon or in
respect hereof or of the Indenture, against the Indenture Trustee, 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

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.

PRINCIPAL SUM: _______________________________________________AND 00/100 DOLLARS
NOTEHOLDER:  CEDE & CO.

     GMAC EDUCATION LOAN FUNDING TRUST-I, a Delaware statutory trust organized
under the laws of the State of Delaware (the "Issuer," which term includes any
successor corporation under the Indenture of Trust, dated as of March 1, 2003
(the "Original Indenture") and the Series 2003-1 Supplemental Indenture of Trust
dated as of March 1, 2003 (as amended, the "Series 2003-1 Supplemental
Indenture," and together with the Original Indenture, the "Indenture"), each
between the Issuer and Zions First National Bank, as Indenture Trustee (the
"Indenture Trustee," which term includes any successor indenture trustee under
the Indenture))

<Page>

for value received, hereby promises to pay to the Noteholder (stated 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 principal 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
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 an Auction Rate, all as determined in
Appendix A of the Series 2003-1 Supplemental Indenture.

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

     Interest payable on this note shall be computed on the assumption that each
year contains 360 days and actual days elapsed and rounding the resultant figure
to the fifth decimal place.

     This note is one of a series of notes of the Issuer designated GMAC ELF
Asset-Backed Notes, Subordinate Class B-1AR Auction Rate Securities, dated the
Closing Date, in the aggregate original principal amount of $14,000,000 (the
"Class B-1 Notes") which have been authorized by the Issuer, and issued by the
Issuer pursuant to the Indenture. The Issuer is, simultaneously with the Class
B-1 Notes, issuing $206,000,000 of its GMAC ELF Student Loan Asset-Backed Notes,
Senior Class A Notes in three classes (collectively, the "Class A 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 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 as
described in the 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 Dates, at a redemption or purchase price
equal to the aggregate current principal balance of all the Notes,

                                      A-2-2
<Page>

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
Auction Rate Securities for which no such failure or defect occurs. All Notes
called for redemption or purchase will cease to bear interest after the
specified redemption or purchase date, provided funds for their payment are on
deposit at the place of payment at the time. If less than all Notes are to be
redeemed or purchased, Notes shall be selected for redemption or purchase as
provided in the Indenture.

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

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.

authorized denominations, bearing interest at the same rate, and for the same
aggregate principal amount will be issued to the designated transferee or

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

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.
