         The Original Indenture, as amended by the First, Second, Third, Fourth,
Fifth, Sixth, Seventh, Eighth, Ninth and Tenth Supplemental Indentures, is
referred to herein as the "Indenture." All capitalized terms used and not
otherwise defined in this Eleventh Supplemental Indenture shall have the
meanings assigned to those terms in the Indenture, except where the context
clearly indicates otherwise. U.S. BANK TRUST NATIONAL ASSOCIATION, a national
banking association, currently acts as the Trustee under the Indenture.

         Pursuant to the Indenture, the Company did grant, bargain, sell, alien,
remise, release, convey, assign, transfer, mortgage, hypothecate, pledge, set
over and confirm to the Trustee all rights, privileges and franchises of the
Company of every kind and description, real, personal or mixed, tangible and
intangible, whether then owned or thereafter acquired by the Company, except any
Excepted Property (as defined in the Indenture), and granted a security interest
therein for the purposes therein expressed.

         The Indenture secures payment of the principal of (and premium, if any)
and interest on the Outstanding Secured Bonds (as defined in the Indenture) and
the performance of the covenants contained in such Outstanding Secured Bonds and
the Indenture.

         The purpose of the First, Second, Fourth, Sixth, Eighth and Ninth
Supplemental Indentures was to confirm the Company's intention that certain real
property (described in the respective Supplemental Indentures) acquired by the
Company after the date of the Original Indenture be subjected to the lien of the
Indenture, and to confirm the substitution of Seattle-First National Bank
(successor by merger to the original Trustee, Security Pacific Bank Washington,
N.A.) as Trustee under the Indenture. The purposes of the Third and Seventh
Supplemental Indentures were to establish and modify, respectively, a series of
bonds designated First Mortgage Bonds, CoBank Series, to be issued to CoBank,
ACB. The purpose of the Fifth Supplemental Indenture was to establish a series
of bonds designated First Mortgage Bonds, Series CFC, to be issued to the
National Rural Utilities Cooperative Finance Corporation.


                                       3



         The purposes of the Tenth Supplemental Indenture were to (i) provide
for the creation of two new series of Bonds, designated New Bonds, 2001 Series
A, and New Bonds, CoBank Series B, and specify the form and provisions of the
Bonds of each such new series, and (ii) amend and restate the Indenture in its
entirety, effective as of and after the Release Date (as defined below), such
that, from and after the Release Date, (A) all Outstanding Secured Bonds issued
on or after the date of the Tenth Supplemental Indenture shall constitute
Obligations as defined in, and be entitled to the benefits of, the Amended and
Restated Indenture (as defined below), and (B) the lien and security interests
arising under the Indenture on the Trust Estate shall terminate and the entire
Trust Estate (as defined in the Indenture) shall be reconveyed and re-assigned
to the Company.

         U.S. Bank Trust National Association, a national banking association
(formerly known as First Trust National Association), has succeeded to the
interest of the Trustee under the Indenture.

         The purpose of this Eleventh Supplemental Indenture are to establish
two new series of Bonds, designated New Bonds, 2002 Series A, and New Bonds,
2002 Series B and specify the form and provisions of the Bonds of each such new
series.

         This Eleventh Supplemental Indenture is amendatory and supplemental to
the Indenture, and, from and after the Release Date (as defined in the Amended
and Restated Indenture attached as Exhibit A to the Tenth Supplemental Indenture
referenced above, upon which Release Date the Amended and Restated Indenture
shall according to its terms amend and restate the Indenture in its entirety),
shall be amendatory and supplemental to such Amended and Restated Indenture and
the series of Bonds established hereunder shall be considered Obligations within
the meaning of such Amended and Restated Indenture.

A.   New Bonds, 2002 Series A. There is hereby established under the Indenture,
     as further amended by this Eleventh Supplemental Indenture, a new series of
     Bonds entitled to the benefits, protection and security of the Indenture,
     as follows:

     (1)  The new series of Bonds is entitled "New Bonds, 2002 Series A."

     (2)  The New Bonds, 2002 Series A shall be governed by the provisions of
          Appendix 1 attached to this Eleventh Supplemental Indenture.

B.   New Bonds, 2002 Series B. There is hereby established under the Indenture,
     as modified by this Eleventh Supplemental Indenture, a new series of Bonds
     entitled to the benefits, protection and security of the Indenture, as
     follows:

     (1)  The new series of Bonds is entitled "New Bonds, 2002 Series B."

     (2)  The New Bonds, 2002 Series B shall be governed by the provisions of
          Appendix 2 attached to this Eleventh Supplemental Indenture.

                                       4


C.   Ratification. Except as expressly amended by this Eleventh Supplemental
     Indenture, the Indenture is in all respects ratified and confirmed and all
     the terms, provisions and conditions of the Indenture shall remain in full
     force and effect, and this Eleventh Supplemental Indenture shall be deemed
     to be a part of the Indenture.

D.   Counterparts. This Eleventh Supplemental Indenture may be executed in any
     number of counterparts, each of such counterparts shall for all purposes be
     deemed to be an original, and all such counterparts shall together
     constitute but one and the same instrument.

E.   Execution Date. Although this Eleventh Supplemental Indenture is dated for
     convenience and for the purpose of reference as of the date set forth in
     the first paragraph hereof, the actual date or dates of execution by the
     Company and by the Trustee are as indicated by their respective

                    ELEVENTH SUPPLEMENTAL INDENTURE OF TRUST
                           (New Bonds, 2002 Series A)

         This Appendix 1 to Eleventh Supplemental Indenture is attached to and
incorporated into that Eleventh Supplemental Indenture dated as of
__________________, 2002, between Chugach Electric Association, Inc. and U.S.
Bank Trust National Association, which Eleventh Supplemental Indenture amends
and supplements that Indenture of Trust dated as of September 15, 1991 (as
previously or hereafter supplemented, modified or amended from time to time, the
"Indenture").

A. General Provisions and Definitions

         All capitalized terms used but not otherwise defined herein shall have
the meanings assigned to those terms in the Indenture, except in cases where the
context clearly indicates otherwise.

B. New Bonds of 2002 Series A and Certain Provisions Relating Thereto

(1) Specific Title, Terms and Forms.

     (a)  The new series of Bonds is entitled "New Bonds, 2002 Series A" (herein
          called the "2002 Series A Bonds"). The forms thereof shall be
          substantially as set forth in Article Two of the Indenture with such
          insertions, omissions, substitutions and variations as may be
          determined by the Officers executing the same as evidenced by their
          execution thereof to reflect the applicable terms of the 2002 Series A
          Bonds.

     (b)  The aggregate principal amount of the 2002 Series A Bonds which may be
          authenticated and delivered and Outstanding is limited to [One Hundred
          Twenty Million Dollars ($120,000,000)]. The 2002 Series A Bonds shall
          be issued in denominations of $1,000 or any multiple thereof. Interest
          shall be computed on the basis of a 360-day year of twelve 30-day
          months.

     (c)  The 2002 Series A Bonds shall bear interest from their date payable on
          [_____________], 2002, and semiannually thereafter on the
          [____________ (___)] day of [______] and the [____________ (___)] day
          of [______] of each year at the rate of ______________ percent (____%)
          per annum and shall mature on [______________], 2012.

                                       1


     (d)  The principal of, and interest on, the 2002 Series A Bonds shall be
          payable at the office or agency of the Trustee at 180 East Fifth
          Street, 3rd Floor, St. Paul, MN 55101. Such location is herein called
          a Place of Payment.

     (e)  The Regular Record Date for the payment of the interest on the 2002
          Series A Bonds payable, and punctually paid or duly provided for, on
          any Interest Payment Date shall be the last day (whether or not a
          business day) of the calendar month next preceding such Interest
          Payment Date.

(2) Exchangeability.

          When the 2002 Series A Bonds are held in a Book-Entry System, the
          delivery of 2002 Series A Bonds, exchanges, transfers and assignment
          of the 2002 Series A Bonds and issuance of the 2002 Series A Bonds
          shall be determined by the provisions of the DTC Letter of
          Representation executed by the Company in connection with such series
          (as the same may amended from time to time). Subject to Section 3.07
          of the Indenture, all 2002 Series A Bonds not held in the Book-Entry
          System shall be fully interchangeable, and, upon surrender at the
          office or agency of the Trustee in a Place of Payment therefor, shall
          be exchangeable for other 2002 Series A Bonds of the same maturity but
          of a different authorized denomination or denominations, as requested
          by the Holder surrendering the same. The Company will execute, and the
          Trustee shall authenticate and deliver, 2002 Series A Bonds whenever
          the same are required for any such exchange.

(3) No Redemption. The 2002 Series A Bonds are not redeemable at any time prior
to maturity.

(4) Book-Entry System, Certificates, Registration and Payment.

     (a)  The 2002 Series A Bonds initially shall be held in a Book-Entry System
          and shall (except to the extent otherwise required by the DTC Letter
          of Representation with respect to the 2002 Series A Bonds) be
          evidenced by one certificate for each maturity, in an amount equal to
          the aggregate principal amount of such maturity.

     (b)  The principal of, premium, if any, and interest on the 2002 Series A
          Bonds shall be payable in lawful money of the United States of
          America. While the 2002 Series A Bonds are held in the Book-Entry
          System, payment of the principal of, premium, if any, and interest on
          the 2002 Series A Bonds shall be made by wire transfer of Federal
          funds or equivalent same-day funds, or in such other manner as
          permitted by the DTC Letter of Representation executed by the Company
          in connection with such series (as the same may be amended from time
          to time), to the account of Cede & Co. In the event the 2002 Series A
          Bonds are no longer held in the Book-Entry System, interest on the
          2002 Series A Bonds shall be payable on each Interest Payment Date by
          check payable to the Holder (except that if so instructed in writing
          by a Holder of $1,000,000 or more of the 2002 Series A Bonds, such
          payments shall be made by wire transfer of Federal Reserve funds on
          the Interest Payment Date), mailed to the Holder at his or her address
          as it appears on the Bond Register on the last day of the calendar
          month prior to the Interest Payment Date, or in such other manner as
          such Holder and the Trustee may determine. Except as may be provided
          in the DTC Letter of Representation with respect to 2002 Series A
          Bonds, payment of principal (other than through operation of a sinking
          fund, if any) shall be made only upon presentation and surrender of
          each 2002 Series A Bond, as the same becomes due, at the office from
          which the Trustee performs the payment function for 2002 Series A
          Bonds.

                                       2


     (c)  The Trustee shall act as Bond Registrar and shall maintain
          registration books for the registration and the registration of
          transfer of the 2002 Series A Bonds.

     (d)  So long as the 2002 Series A Bonds are held in the Book-Entry System,
          the registered Holder of all of the 2002 Series A Bonds shall be DTC,
          and the 2002 Series A Bonds shall be registered in the name of Cede &
          Co., as nominee for DTC pursuant to the DTC Letter of Representation
          with respect to 2002 Series A Bonds, as amended from time to time, and
          the provisions of such Letter of Representation shall be incorporated
          herein by this reference.

     (e)  Upon initial issuance, the ownership of the 2002 Series A Bonds shall
          be registered by the Trustee on the Bond Register in the name of Cede
          & Co., as nominee of DTC. The Trustee and the Company may treat DTC
          (or its nominee) as the sole and exclusive registered Holder of the
          2002 Series A Bonds registered in its name for the purposes of payment
          of the principal of or interest on the 2002 Series A Bonds, giving
          notice as required under the Indenture, registering the transfer of
          2002 Series A Bonds, obtaining any consent or other action to be taken
          by the Holders and for all other purposes whatsoever; and neither the
          Trustee nor the Company shall be affected by any notice to the
          contrary. Neither the Trustee nor the Company shall have any
          responsibility or obligation to any person claiming a beneficial
          ownership interest in the 2002 Series A Bonds under or through DTC or
          any DTC Participant, or any other person which is not shown on the
          Bond Register as being a registered Holder, with respect to the
          accuracy of any records maintained by DTC or any DTC Participant; the
          payment by DTC or any DTC Participant of any amount in respect of the
          principal of or interest on the 2002 Series A Bonds; any notice or
          direction which is permitted or required to be given to or received

                                       3


          from Holders under the Indenture; or any consent given or other action
          taken by DTC as Holder; nor shall any DTC Participant or any such
          Person be deemed to be a third party beneficiary of any Holders'
          rights under the Indenture. The Trustee shall pay from moneys
          available hereunder all principal of and premium, if any, and interest
          on the 2002 Series A Bonds only to or upon the order of DTC or its
          designee, and all such payments shall be valid and effective to fully
          satisfy and discharge the Company's obligations with respect to the
          principal of and premium, if any, and interest on the 2002 Series A
          Bonds to the extent of the sum or sums so paid. So long as the 2002
          Series A Bonds are held in the Book-Entry System, no person other than
          DTC shall receive an authenticated Bond for each separate stated
          maturity evidencing the obligation of the Company to make payments of
          principal of and premium, if any, and interest with respect to the
          2002 Series A Bonds pursuant to the Indenture. Upon delivery by DTC to
          the Trustee of DTC's written notice to the effect that DTC has
          determined to substitute a new nominee in place of Cede & Co., and
          subject to the provisions of the Indenture with respect to transfers
          of 2002 Series A Bonds, the term "Cede & Co." in the Indenture shall
          refer to such new nominee of DTC.

(5)      Availability of Bond Certificates.

          At any time it determines that it is in the best interests of the
          Holders, the Company may notify DTC and the Trustee, whereupon DTC
          will, if consistent with DTC's then-current policies, notify the DTC
          Participants, of the availability through DTC of 2002 Series A Bond
          certificates. In such event, the Company shall prepare and execute and
          the Trustee shall issue, transfer and exchange, at the expense of the
          Company, 2002 Series A Bond certificates as requested in writing by
          DTC in appropriate amounts. DTC may determine to discontinue providing
          its services with respect to the 2002 Series A Bonds at any time by
          giving written notice to the Company and the Trustee and discharging
          its responsibilities with respect thereto under applicable law. If DTC
          resigns as securities depository for the 2002 Series A Bonds, 2002
          Series A Bond certificates shall be delivered pursuant to this
          Section. Under such circumstances (if there is no successor securities
          depository), the Company and the Trustee shall be obligated to deliver
          2002 Series A Bonds as described in the Indenture, provided that the
          expense in connection therewith shall be paid by the Company. In the
          event that certificates for 2002 Series A Bonds are issued, the
          provisions of the Indenture shall apply to, among other things, the


                                       4


          transfer and exchange of such certificates and the method of payment
          of principal of, premium, if any, and interest on such 2002 Series A
          Bonds. Whenever DTC requests the Company to do so, the Company will
          cooperate with DTC in taking appropriate action after written notice
          (a) to make available one or more separate certificates evidencing the
          2002 Series A Bonds to any DTC Participant having 2002 Series A Bonds
          credited to its DTC account, or (B) to arrange for another securities
          depository to maintain custody of certificates evidencing the 2002
          Series A Bonds.

(6) Use of Proceeds. The Company shall use the proceeds from the sale of the
2002 Series A Bonds:

     (a)  to pay amounts owing by the Company with respect to the Company's 1991
          Series A Bonds due 2002;

     (b)  to redeem any Outstanding Bonds (and pay the redemption premium
          thereon);

     (c)  to pay the settlement amount owing by the Company to its counterparty
          upon termination or expiration of a Treasury rate-lock contract to
          which the Company is a party; and

     (d)  for such other purposes as the Company may determine.

(7) Credit Enhancer.

2.05 Designation of the 2002 Series B Bonds as Bonds to Be Held in
     Book-Entry System; Appointment of Securities Depository for
     2002 Series B Bonds

         1. The 2002 Series B Bonds initially shall be held in a Book-Entry
System and shall (except to the extent otherwise required by the DTC Letter of
Representation with respect to the 2002 Series B Bonds) be evidenced by one
certificate for each maturity, in an amount equal to the aggregate principal
amount of such maturity. Unless otherwise determined by an Officer of the
Company, DTC is hereby appointed as the initial Securities Depository for the
2002 Series B Bonds.

         2. While the 2002 Series B Bonds are held in the Book-Entry System,
payment of the principal of, premium, if any, and interest on the 2002 Series B
Bonds shall be made by wire transfer of Federal funds or equivalent same-day
funds, or in such other manner as permitted by the DTC Letter of Representation
executed by the Company in connection with such series (as the same may be
amended from time to time), to the account of Cede & Co. Except as may be
provided in the DTC Letter of Representation with respect to 2002 Series B
Bonds, payment of principal (other than through operation of a sinking fund, if
any) shall be made only upon presentation and surrender of each 2002 Series B
Bond, as the same becomes due, at the office from which the Trustee performs the
payment function for 2002 Series B Bonds.

                                       11


         3. So long as the 2002 Series B Bonds are held in the Book-Entry
System, the registered Holder of all of the 2002 Series B Bonds shall be DTC,
and the 2002 Series B Bonds shall be registered in the name of Cede & Co., as
nominee for DTC pursuant to the DTC Letter of Representation with respect to
2002 Series B Bonds, as amended from time to time, and the provisions of such
Letter of Representation shall be incorporated herein by this reference. Upon
initial issuance, the ownership of the 2002 Series B Bonds shall be registered
by the Trustee on the Register in the name of Cede & Co., as nominee of DTC. The
Trustee and the Company may treat DTC (or its nominee) as the sole and exclusive
registered Holder of the 2002 Series B Bonds registered in its name for the
purposes of payment of the principal of or interest on the 2002 Series B Bonds,
giving notice as required under the Indenture, registering the transfer of 2002
Series B Bonds, obtaining any consent or other action to be taken by the Holders
and for all other purposes whatsoever; and neither the Trustee nor the Company
shall be affected by any notice to the contrary. Neither the Trustee nor the
Company shall have any responsibility or obligation to any person claiming a
beneficial ownership interest in the 2002 Series B Bonds under or through DTC or
any DTC Participant, or any other person which is not shown on the Register as
being a registered Holder, with respect to the accuracy of any records
maintained by DTC or any DTC Participant; the payment by DTC or any DTC
Participant of any amount in respect of the principal of or interest on the 2002
Series B Bonds; any notice or direction which is permitted or required to be
given to or received from Holders under the Indenture; or any consent given or
other action taken by DTC as Holder; nor shall any DTC Participant or any such
Person be deemed to be a third party beneficiary of any Holders' rights under
the Indenture. The Trustee shall pay from moneys available hereunder all
principal of and premium, if any, and interest on the 2002 Series B Bonds only
to or upon the order of DTC or its designee, and all such payments shall be
valid and effective to fully satisfy and discharge the Company's obligations
with respect to the principal of and premium, if any, and interest on the 2002
Series B Bonds to the extent of the sum or sums so paid. So long as the 2002
Series B Bonds are held in the Book-Entry System, no person other than DTC shall
receive an authenticated Bond for each separate stated maturity evidencing the
obligation of the Company to make payments of principal of and premium, if any,
and interest with respect to the 2002 Series B Bonds pursuant to the Indenture.
Upon delivery by DTC to the Trustee of DTC's written notice to the effect that
DTC has determined to substitute a new nominee in place of Cede & Co., and
subject to the provisions of the Indenture with respect to transfers of 2002
Series B Bonds, the term "Cede & Co." in the Indenture shall refer to such new
nominee of DTC.

         4. At any time it determines that it is in the best interests of the
Holders, the Company may notify DTC and the Trustee, whereupon DTC will, if
consistent with DTC's then-current policies, notify the DTC Participants, of the
availability through DTC of 2002 Series B Bond certificates. In such event, the
Company shall prepare and execute and the Trustee shall issue, transfer and
exchange, at the expense of the Company, 2002 Series B Bond certificates as
requested in writing by DTC in appropriate amounts. DTC may determine to
discontinue providing its services with respect to the 2002 Series B Bonds at
any time by giving written notice to the Company and the Trustee and discharging
its responsibilities with respect thereto under applicable law. If DTC resigns
as Securities Depository for the 2002 Series B Bonds, 2002 Series B Bond
certificates shall be delivered pursuant to this Section. Under such
circumstances

                                       12


(if there is no successor Securities Depository), the Company and
the Trustee shall be obligated to deliver 2002 Series B Bonds as described in
the Indenture, provided that the expense in connection therewith shall be paid
by the Company. In the event that certificates for 2002 Series B Bonds are
issued, the provisions of the Indenture shall apply to, among other things, the
transfer and exchange of such certificates and the method of payment of
principal of, premium, if any, and interest on such 2002 Series B Bonds.
Whenever DTC requests the Company to do so, the Company will cooperate with DTC
in taking appropriate action after written notice (a) to make available one or
more separate certificates evidencing the 2002 Series B Bonds to any DTC
Participant having 2002 Series B Bonds credited to its DTC account, or (B) to
arrange for another securities depository to maintain custody of certificates
evidencing the 2002 Series B Bonds.

         5. Notwithstanding any provision herein to the contrary, so long as the
Book-Entry System of transfers provided for in this Section shall remain in
effect with respect to the 2002 Series B Bonds, (a) every transfer of such 2002
Series B Bonds made in accordance with the Auction Procedures set forth in
Exhibit A, (b) every remarketing of such 2002 Series B Bonds (or portions

                    Auction Period to be in effect upon the effectiveness of
                    such Auction Mode, which Auction Period shall be any of the
                    Auction Periods referred to in Exhibit A, or (B) the
                    designated Interest Mode is a Term Mode, the duration of the
                    initial Interest Period thereof, which Interest Period shall
                    end on the last calendar day of any June or December
                    specified in such Officer's Certificate.

                                       17


         Upon (X) receipt by the other Notice Parties of such Officer's
Certificate, (Y) receipt by the Tender Agent of the items referred to in
subsection 1 of Section 4.02 and (Z) the giving of the notice provided in clause

          (b)  Limitations on Determinations. No change to any Interest Mode or
               in the Interest Period for any Term Mode shall be made for the
               2002 Series B Bonds by an Officer's Certificate pursuant to
               clause (a) of this Section, unless:

               (i)  Favorable Opinion of Bond Counsel: such Officer's
                    Certificate is accompanied by, and in addition there is
                    delivered to the Trustee, the Bond Insurer, the Tender Agent
                    and the Remarketing Agent on the first day of such Interest
                    Mode or Interest Period, as the case may be, a Favorable
                    Opinion of Bond Counsel,

               (ii) Consent of Bond Insurer: such Officer's Certificate is
                    accompanied by a written consent of the Bond Insurer to such
                    change in Interest Mode or Interest Period,

               (iii) Liquidity Facility Requirement: except in the case of a
                    change to the Auction Mode or the Fixed Mode, the Liquidity
                    Facility shall be in an amount at least equal to the
                    Liquidity Facility Requirement applicable to the Interest
                    Mode to become effective,

               (iv) Qualified Interest Period: if the Interest Mode to become
                    effective for the 2002 Series B Bonds is a Term Mode, the
                    duration of the first Interest Period thereof designated by
                    such Officer's Certificate is in accordance with the
                    provisions of Section 3.02, and

               (v)  Book-Entry System: if the Interest Mode to become effective
                    for the 2002 Series B Bonds is an Auction Mode, the 2002
                    Series B Bonds shall, on the Mode Adjustment Date, be a
                    Book-Entry Only 2002 Series B Bond.

                                       18


          (c)  Restoration of Positions. If, after notice to any Person of any
               change in the Interest Mode or Interest Period for the 2002
               Series B Bonds, such change may not be effected on the Mode
               Adjustment Date specified therefor in the Officer's Certificate
               designating such change because of any failure to satisfy the
               conditions of clause (b) of this Section, then the 2002 Series B
               Bonds shall remain in the Interest Mode which they are then in or
               remain subject to the same Interest Period as then is applicable,
               as the case may be; provided, however, that if the proposed
               change was from the Term Mode to any other Interest Mode and the
               Company causes to be delivered to the Trustee, the Bond Insurer,
               the Tender Agent and the Remarketing Agent a Favorable Opinion of
               Bond Counsel, then, so long as the Liquidity Facility then in
               effect (taking into account any amendments being made thereto in
               connection therewith) shall provide that the amount available to
               be drawn or advanced thereunder shall be at least equal to the
               principal amount of the Outstanding 2002 Series B Bonds (other
               than 2002 Series B Bank Bonds) plus 31 days' interest thereon
               computed at a rate per annum equal to the Maximum Rate and on the
               basis of a 365-day year, the 2002 Series B Bonds shall be changed
               to the Weekly Mode. In any such event, the 2002 Series B Bonds
               shall be subject to mandatory tender as and to the extent
               provided in clause (c)(iii) of Section 3.06.

3.02 Duration of Interest Modes and Interest Periods

         The duration of Interest Modes and Interest Periods will be as follows:

          (a)  Interest Modes. Each Interest Mode for the 2002 Series B Bonds
               other than the Fixed Mode shall extend through the day prior to
               the effective date of any other Interest Mode for the 2002 Series
               B Bonds established in accordance with Section 3.01. Any Fixed
               Mode for the 2002 Series B Bonds shall extend to the stated
               maturity date of the 2002 Series B Bonds.

          (b)  Interest Periods Generally. No Interest Period for any 2002
               Series B Bond (or portion thereof) during a Flexible Mode or a
               Term Mode shall extend beyond (1) the fifth (5th) day preceding
               the Liquidity Facility Expiration Date or (2) the day prior to
               the effective date of any other Interest Mode for the 2002 Series
               B Bonds to become effective pursuant to the prior Officer's
               Certificate given in accordance with clause (a) of Section 3.01.

          (c)  Interest Periods During Auction Mode. Each Interest Period for
               each 2002 Series B Bond (or beneficial ownership interest
               therein) while in an Auction Mode shall be the same as each
               Auction Period with respect thereto, which Auction Periods shall
               be determined in the manner provided in Exhibit A.

          (d)  Interest Periods During Flexible Mode. The Interest Period for
               each 2002 Series B Bond (or beneficial ownership interest
               therein) while in a Flexible Mode shall be the period determined
               by the Remarketing Agent, on or before the Rate Adjustment Date
               therefor, to be the Interest Period which, in its judgment, will
               produce the greatest likelihood of the lowest overall debt
               service costs on the 2002 Series B Bonds prior to the maturity


                                       19


               thereof, given prevailing market conditions. The Remarketing
               Agent may determine different Interest Periods for different 2002
               Series B Bonds (or beneficial ownership interests therein) on or
               before the same Rate Adjustment Date. Each Interest Period for
               any 2002 Series B Bond (or beneficial ownership interest therein)
               while in a Flexible Mode shall commence on the first day of such
               Flexible Mode for such 2002 Series B Bond (or beneficial
               ownership interest therein) or on the day immediately succeeding
               the immediately preceding Interest Period for such 2002 Series B
               Bond (or beneficial ownership interest therein) during such
               Flexible Mode, shall end on a day preceding a Business Day, and
               shall be not less than one nor more than 270 days in length. No
               Interest Period for any 2002 Series B Bond (or beneficial
               ownership interest therein) while in a Flexible Mode shall end
               later than the day preceding any redemption date described in
               subsection 1 or 2 of Section 2.06, unless the principal amount of
               2002 Series B Bonds (or beneficial ownership interests therein)
               with an Interest Period which ends on or prior to such preceding
               day is at least equal to the principal amount of 2002 Series B
               Bonds to be redeemed on such redemption date pursuant to said
               subsection 1 or 2 of Section 2.06, as the case may be.

          (e)  Interest Period During Term Modes. Each Interest Period for any
               2002 Series B Bond (or beneficial ownership interest therein)
               while in a Term Mode shall commence on the Mode Adjustment Date
               with respect thereto or on the day immediately succeeding the
               immediately preceding Interest Period for such 2002 Series B Bond
               during such Term Mode. The initial Interest Period of each Term
               Mode for the 2002 Series B Bonds shall end on the last calendar
               day of any June or December specified in the Officer's
               Certificate designating such Interest Mode pursuant to clause (a)
               of Section 3.01 which occurs at least one year after the
               effective date of such Interest Mode. Each successive Interest
               Period during such Term Mode shall end on the day immediately
               preceding the anniversary of the last Interest Payment Date for
               interest accrued in the immediately preceding Interest Period
               which occurs the same number of 12-month periods after the first
               day of such successive Interest Period as the number of 12-month
               periods or portions thereof during the initial Interest Period in
               such Term Mode, unless changed by Officer's Certificate pursuant
               to Section 3.01.

3.03 Determination of Interest Rates; Effectiveness Thereof

         The various interest rates for the 2002 Series B Bonds will be
determined as follows, and shall be effective for the periods described below:

          (a)  Auction Mode Rate. During each Auction Mode for 2002 Series B
               Bonds, the Auction Mode Rates to be in effect from time to time
               shall be determined by the Auction Agent and notice thereof shall
               be given in the manner provided in Exhibit A, and each such
               Auction Mode Rate shall be effective for the Auction Period to
               which such Auction Mode Rate relates; provided, however, that the
               Auction Mode Rate for the Auction Period commencing on the
               Delivery Date shall be determined by J.P. Morgan Securities Inc.,
               in its capacity as the initial Broker-Dealer, as the lowest rate
               which, in the judgment of such Broker-Dealer, is necessary to


                                       20


               enable the 2002 Series B Bonds (or beneficial ownership interests
               therein) to be sold to the initial purchasers thereof at a price
               (without regard to accrued interest) equal to 100% of the
               principal amount thereof; and provided, further, that in the
               event of a change to the Auction Mode from another Interest Mode,
               the Auction Mode Rate for the Auction Period commencing on the
               Mode Adjustment Date applicable thereto shall be determined by
               such Broker-Dealer as shall be specified by the Company as the
               lowest rate which, in the judgment of such Broker-Dealer, is
               necessary to enable the 2002 Series B Bonds (or beneficial
               ownership interests therein) to be remarketed on such Mode
               Adjustment Date at a price (without regard to accrued interest)
               equal to 100% of the principal amount thereof.

          (b)  Daily Rate. During each Daily Mode for 2002 Series B Bonds, by
               12:30 p.m., New York City time, on each Business Day for the
               Remarketing Agent, the Remarketing Agent shall determine the
               Daily Rate for the 2002 Series B Bonds by determining, in the
               manner described in clause (f) of this Section, the Market Rate
               therefor on such day, which Daily Rate shall be effective for the
               Interest Period beginning on such Business Day and ending on the
               day preceding the next succeeding Business Day.

          (c)  Weekly Rate. During each Weekly Mode for the 2002 Series B Bonds,
               by 5:00 p.m., New York City time, on the last Business Day for
               the Remarketing Agent before the commencement of such Weekly Mode
               and before each succeeding Wednesday (or such other day as may be
               specified by the Remarketing Agent after notice to the Trustee,
               the Tender Agent and the Holders of the 2002 Series B Bonds)
               thereafter during such Weekly Mode, the Remarketing Agent shall
               determine the Weekly Rate for the 2002 Series B Bonds by
               determining, in the manner described in clause (f) of this
               Section, the Market Rate therefor on such day, which Weekly Rate
               shall be effective for the Interest Period beginning on Wednesday
               of such week and ending on the next succeeding Tuesday.

          (d)  Flexible Rate. By not later than 12:30 p.m., New York City time,
               on or before the first Business Day for the Remarketing Agent in
               each Interest Period for each 2002 Series B Bond (or beneficial
               ownership interest therein) which is in a Flexible Mode, the
               Remarketing Agent shall determine the Flexible Rate for such 2002
               Series B Bond (or beneficial ownership interest therein), in each
               case by determining, in the manner described in clause (f) of
               this Section, the Market Rate therefor on such day, which
               Flexible Rate shall be effective for such Interest Period.

          (e)  Term Rate; Fixed Rate. On any date designated by the Remarketing
               Agent which is not more than 35 days preceding nor later than the
               last Business Day for the Remarketing Agent preceding each
               Interest Period for 2002 Series B Bonds during which such 2002
               Series B Bonds are in a Term Mode or the Fixed Mode, the
               Remarketing Agent shall determine the Term Rate or the Fixed
               Rate, as the case may be, for the 2002 Series B Bonds by
               determining, in the manner described in clause (f) of this
               Section, the Market Rate therefor on such day, which Term Rate or
               Fixed Rate, as the case may be, shall be effective for such
               Interest Period.

                                       21


          (f)  Procedure for Market Rate Determination. The Remarketing Agent
               shall make each determination of the Market Rate for any 2002
               Series B Bond (or beneficial ownership interest therein) pursuant
               to this Section by determining in its judgment the minimum
               interest rate necessary to be borne by such 2002 Series B Bond
               (or beneficial ownership interest therein) for the relevant
               Interest Period to enable the Remarketing Agent to remarket such
               2002 Series B Bond (or beneficial ownership interest therein) on
               the Rate Adjustment Date therefor at a price (without regard to
               accrued interest) equal to 100% of the principal amount thereof;
               provided, however, that in no event shall any rate so determined
               exceed the Maximum Rate. If for any reason the Remarketing Agent
               fails to determine the Market Rate for any 2002 Series B Bond (or
               beneficial ownership interest therein) on a Rate Determination
               Date, or any Market Rate for any 2002 Series B Bond (or
               beneficial ownership interest therein) determined by the
               Remarketing Agent on a Rate Determination Date is determined by a
               court of competent jurisdiction to be invalid or unenforceable,
               then, commencing on such Rate Determination Date or the date with
               respect to which such court's determination shall be effective,
               as the case may be, such 2002 Series B Bond (or beneficial
               ownership interest therein) shall bear interest at a rate equal
               to the One Week LIBOR Rate.

3.04 Notice of Interest Rates and Interest Modes

         Notice of interest rates and Interest Modes will be given as follows:

          (a)  Notice to the Trustee, the Broker-Dealers, the Tender Agent and

               Flexible Mode made by it pursuant to clause (d) of Section 3.02,
               which notice shall be in writing (including by facsimile or other
               electronic means) or may be by telephone, promptly confirmed in
               writing (including by facsimile or other electronic means). Such

as required by subsection 2 of Section 3.08.


                                       32


         2. If, at any time, the Company shall obtain a renewal or extension of
the Liquidity Facility then in effect (or a written commitment which evidences
such renewal or extension) on substantially the same terms, unless the Agent
Bank already shall have given notice thereof, the Company shall promptly give
notice to the other Notice Parties of such renewal or extension, and the Tender
Agent shall promptly give notice thereof to the Holders of the 2002 Series B
Bonds. Any such renewal or extension shall not constitute substitution of a
Liquidity Facility.

         3. At any time prior to the giving by the Tender Agent, pursuant to
subsection 2 of Section 3.08, of notice of the mandatory tender of the 2002
Series B Bonds as a result of the expiration of the Liquidity Facility then in

2002 Series B Bonds on the Substitution Date therefor (which shall be the date
of the mandatory tender for purchase established pursuant to clause (c)(ii) of
Section 3.06). Promptly following such Substitution Date, the Tender Agent shall

default having continued for fifteen (15) Business Days after receipt by such
Bank of written notice of such default from the Company, the Bond Insurer or the
Trustee, or (d) bankruptcy, insolvency, receivership, liquidation or other
similar proceedings instituted by or against such Bank, the Company may, with
the consent of the Bond Insurer, or shall, at the written direction of the Bond
Insurer, cause another bank to be substituted for the Bank with respect to which
the event described in (a), (b), (c) or (d) shall have occurred under the
Liquidity Facility then in effect or to issue or enter into a Substitute
Liquidity Facility, as the case may be, on a stated date (which shall be the
Substitution Date). In that event, the 2002 Series B Bonds shall be subject to
mandatory tender for purchase on the Substitution Date, and the Tender Agent
shall give notice thereof in the manner provided in subsection 2 of Section
3.08.

         5. In connection with the delivery of (a) any agreement or instrument
permitted pursuant to subsection 1 of this Section or (b) any Substitute
Liquidity Facility permitted pursuant to subsection 3 or 4 of this Section, the
Company shall, with the written consent of the Bond Insurer, be authorized to
amend the provisions of this Eleventh Supplemental Indenture if and to the
extent necessary to give effect to such agreement or instrument or such
Substitute Liquidity Facility, as the case may be. Notwithstanding the
foregoing, no such amendment shall be or become effective unless the Company
shall have received a Favorable Opinion of Bond Counsel, which Opinion shall, in
addition, state that such amendment will not adversely affect the rights of the
Holders of the 2002 Series B Bonds.

         6. Promptly following the conversion of the 2002 Series B Bonds to the

substitute or additional bond insurance policy insuring the 2002 Series B Bonds
issued by a bond insurer with a financial strength rating by Moody's and S&P of
at least "Aa3" and "AA-", respectively. In such event, the 2002 Series B Bonds
shall be subject to mandatory tender as provided in clause (c)(viii) of Section
3.06, and the Tender Agent shall give notice thereof in the manner provided in
subsection 2 of Section 3.08.

         2. In connection with the delivery of any Substitute Bond Insurance
Policy permitted pursuant to subsection 1 of this Section, the Company shall be

5. 2002 Series B BANK BONDS

5.01 Remarketing of 2002 Series B Bank Bonds

         1. With respect to each particular 2002 Series B Bank Bond, unless such
2002 Series B Bank Bond shall have been purchased by the Bank(s) (or any nominee
or nominees thereof) pursuant to a mandatory tender described in clause (c)(i)
or (c)(vii) of Section 3.06, the Remarketing Agent shall use its best efforts to
remarket such 2002 Series B Bank Bond at a price equal to the principal amount
thereof plus, in the event the 2002 Series B Bonds (other than 2002 Series B
Bank Bonds) are subject to an Interest Mode other than the Flexible Mode,
accrued interest, if any, to the date of such remarketing (computed in
accordance with the provisions of subsection 3 of this Section 5.01).
Notwithstanding anything to the contrary contained in this Eleventh Supplemental
Indenture, if upon the termination of the Liquidity Facility the Bank(s) (or any
nominee or nominees thereof) shall be the Holder of any 2002 Series B Bank Bond,
unless otherwise agreed by the Remarketing Agent, the Remarketing Agent shall be
obligated to use its best efforts to remarket such 2002 Series B Bank Bond in
accordance with the provisions of this Section only until the 60th day following
the date of purchase by the Bank(s) (or any nominee or nominees thereof) of such
2002 Series B Bank Bond.

         2. In attempting to remarket any 2002 Series B Bank Bond, the
Remarketing Agent shall treat such 2002 Series B Bank Bond for all purposes as
if it were governed by the Interest Mode which governs the 2002 Series B Bonds
(other than 2002 Series B Bank Bonds).

         3. Unless otherwise provided in a Liquidity Facility, by becoming a
Holder or beneficial owner of a 2002 Series B Bank Bond, the Bank(s) agree to
transfer (or cause any nominee(s) or transferee(s) thereof to transfer) such
Bond to any Person to which such Bond is remarketed by or through the
Remarketing Agent, but only, however, against receipt of a purchase price
therefor equal to the principal amount thereof plus, in the event the 2002
Series B Bonds (other than 2002 Series B Bank Bonds) are subject to an Interest
Mode other than the Flexible Mode, accrued interest, if any, to the date of such
remarketing, with such accrued interest being computed at the 2002 Series B Bond
Rate or Rates in effect for the period beginning on the later of (i) the Bank
Purchase Date with respect to such 2002 Series B Bank Bond and (ii) the most
recent Interest Payment Date relating to such 2002 Series B Bank Bond on which
interest accrued on such Bond has been paid in full and ending on the day
preceding the day of such remarketing. If more than one 2002 Series B Bank Bond
shall be owned by the Bank(s) (or any nominee(s) or transferee(s) thereof), the
Tender Agent, in its sole discretion, shall select the particular 2002 Series B
Bank Bond(s) that are so remarketed. If a 2002 Series B Bank Bond is transferred
by the Bank(s) (or any nominee(s) or transferee(s) thereof) in accordance with
the previous sentence, the Company agrees to pay to the Agent Bank, for the
account of the Bank(s), or to such transferee(s), as the case may be, on the
date of such remarketing, the amount of interest, if any, resulting from the
Bank Rate or Rates in effect from time to time during the period referred to in
the preceding sentence being in excess of such 2002 Series B Bond Rate or Rates

                                       35



in effect during such period (said amount being referred to herein as the
"Differential Interest Amount"). In the event that the Bank(s) is (or are)
entitled (pursuant to its (or their) Liquidity Facility) to elect not to so
transfer any such 2002 Series B Bond, and the Bank(s) so elect, the Tender Agent
shall, upon notice thereof from the Agent Bank, promptly notify the Company and
the Remarketing Agent of such fact by telephone, promptly confirmed in writing
(including by facsimile or other electronic means), and such 2002 Series B Bond
thereupon shall cease to be a 2002 Series B Bank Bond.

         4. In the event that the Remarketing Agent shall identify a purchaser
for any 2002 Series B Bank Bond pursuant to the provisions of subsection 1 of
this Section, the Remarketing Agent shall give notice thereof to the Tender
Agent, which notice shall specify the principal amount of the 2002 Series B Bank
Bond(s) for which the Remarketing Agent has identified a purchaser and the
purchase price thereof (which shall be the principal amount thereof plus, in the
event the 2002 Series B Bonds (other than 2002 Series B Bank Bonds) are subject
to an Interest Mode other than the Flexible Mode, accrued interest, if any, to
the date of the proposed remarketing thereof (computed in accordance with the
provisions of subsection 3 of this Section 5.01)). If such notice shall be given
by 12:30 p.m., New York City time, on a Business Day, then the date of the
giving of such notice shall be the date of such remarketing. If such notice
shall be given after 12:30 p.m., New York City time, on a Business Day, then the
next succeeding Business Day shall be the date of such remarketing. Promptly
following the receipt of any such notice, the Tender Agent shall notify the
Company and the Agent Bank thereof by telephone, promptly confirmed in writing
(including by facsimile or other electronic means), which notice shall specify
the principal amount of the 2002 Series B Bank Bond(s) for which the Remarketing
Agent has identified a purchaser, and the purchase price thereof.

         5. Except in a case where the Bank(s) shall have elected not to sell
any 2002 Series B Bank Bond as permitted by subsection 3 of this Section 5.01,
by not later than 2:30 p.m., New York City time, on the remarketing date for any
2002 Series B Bank Bond(s) for which the Remarketing Agent has identified a
purchaser, in exchange for possession of such 2002 Series B Bond(s), the
Remarketing Agent shall deliver or cause to be paid, in immediately available
funds, to the Tender Agent for deposit in the 2002 Series B Bond Remarketing
Proceeds Account, the purchase price for such 2002 Series B Bank Bond(s).

         6. Notwithstanding anything to the contrary contained herein, in the
event that any 2002 Series B Bank Bonds shall be Outstanding following the
conversion of the 2002 Series B Bonds to an Auction Mode, all references in this
Section 5.01 to the "Remarketing Agent" shall be deemed to refer to the
Broker-Dealers, and all references in this Section 5.01 to the "remarketing" of
any such 2002 Series B Bank Bonds shall be deemed to refer to the transfer of
2002 Series B Bonds in accordance with the Auction Procedures set forth in
Exhibit A.

Bond ceases to be a 2002 Series B Bank Bond, as provided in subsection 3 of
Section 5.01 and (c) the maturity or redemption date thereof, at an annual rate
equal to the Bank Rate or Rates in effect from time to time during such period
computed on the basis of a 365 or 366-day year, as applicable, for the actual
number of days elapsed.

2. Unless otherwise provided in the Liquidity Facility, interest on a 2002
Series B Bank Bond shall be paid (i) if the 2002 Series B Bonds (other than 2002
Series B Bank Bonds) shall be subject to the Auction Mode, the Daily Mode or the
Weekly Mode, on each Interest Payment Date applicable to such Interest Mode and
(ii) if the 2002 Series B Bonds (other than 2002 Series B Bank Bonds) shall be
subject to the Term Mode, the Fixed Mode or the Flexible Mode, on each Monthly
Payment Date, commencing with the first (1st) Monthly Payment Date to occur
after the Bank Purchase Date with respect to such 2002 Series B Bank Bond.

3. Notwithstanding anything to the contrary contained herein, on the Bank
Purchase Date with respect any 2002 Series B Bank Bond, the amount of accrued
interest, if any, included in the purchase price of such 2002 Series B Bank Bond
shall be paid to the Agent Bank, for the account of the Bank(s).

5.03  Principal Repayment of 2002 Series B Bank Bonds

         A particular 2002 Series B Bank Bond shall, as to the repayment of

consisting of a 2002 Series B Bond Liquidity Proceeds Account and a 2002 Series
B Bond Remarketing Proceeds Account. The 2002 Series B Bond Purchase Fund and
the Accounts therein shall not constitute funds or accounts for purposes of the
Indenture or the Indenture. Amounts on deposit in the 2002 Series B Bond
Purchase Fund shall not be commingled with the amounts held in any fund or
account under the Indenture or the Indenture. All amounts received by the Tender
Agent from the Remarketing Agent representing the Purchase Price of 2002 Series
B Bonds remarketed by the Remarketing Agent shall be deposited in the 2002
Series B Bond Remarketing Proceeds Account in the 2002 Series B Bond Purchase


                                       37

deemed tendered for purchase shall be deposited in the 2002 Series B Bond
Liquidity Proceeds Account in the 2002 Series B Bond Purchase Fund. All amounts

that there shall not be sufficient funds on deposit in the 2002 Series B Bond
Purchase Fund to purchase all 2002 Series B Bonds subject to purchase on a
particular date as a result of any Bank failing to honor its commitment to
advance funds under the Liquidity Facility, the Tender Agent shall select the
particular 2002 Series B Bonds (or portions thereof or beneficial interests
therein) to be so purchased at random in such manner as the Tender Agent in its
discretion may deem fair and appropriate; and provided, further, that any funds
on deposit in the 2002 Series B Bond Liquidity Proceeds Account in the 2002

be returned to the Agent Bank, in immediately available funds, by 3:00 p.m., New
York City time, on the date on which such funds shall have been received by the
Tender Agent.

         All moneys deposited in the 2002 Series B Bond Purchase Fund shall be
held in trust by the Tender Agent and applied only for the purposes set forth
in, and in accordance with the provisions of, this Eleventh Supplemental
Indenture. The 2002 Series B Bond Purchase Fund shall be a trust fund for such
purposes. Amounts on deposit in the 2002 Series B Bond Purchase Fund shall not
be commingled with any other funds held by the Tender Agent, and all amounts on
deposit in such Fund are hereby pledged and assigned to the purchase of the 2002
Series B Bonds in accordance with the terms hereof. Such amounts on deposit in
the 2002 Series B Bond Purchase Fund hereby pledged and assigned shall
immediately be subject to the lien of this pledge without any physical delivery

as against all parties having claims of any kind in tort, contract or otherwise
against the Company, irrespective of whether such parties have notice thereof.

6.03 No Investment

         Amounts on deposit in the 2002 Series B Bond Purchase Fund shall be
held in cash, uninvested.

6.04 No Lien for Trustee or Tender Agent

         Notwithstanding anything in the Indenture or this Eleventh Supplemental
Indenture to the contrary, neither the Trustee nor the Tender Agent shall have
any right to, or lien whatsoever upon, any of the amounts on deposit in the 2002


                                       38

to an Interest Mode other than the Auction Mode or the Fixed Mode, the Company
shall appoint the initial Tender Agent for the 2002 Series B Bonds, which
appointment shall be made at such time as shall be necessary in order to enable

2002 Series B Bonds (or portions thereof or beneficial ownership interests
therein) and the 2002 Series B Bonds (or beneficial ownership interests therein)
delivered pursuant to such notice for purchase in accordance with the Eleventh
Supplemental Indenture, the Tender Agent shall deliver to the Person delivering
such notice and such 2002 Series B Bonds (or beneficial ownership interests
therein) written evidence of the Tender Agent's receipt of such materials. The
Tender Agent shall promptly return any such notice (together with the 2002
Series B Bonds (or beneficial ownership interests therein) submitted in
connection therewith) that is incomplete or improperly completed or not
delivered by the date and time required hereunder to the Person submitting such
notice upon surrender of the receipt, if any, issued therefor. The Tender
Agent's determination of whether any such notice is properly completed or
delivered on a timely basis shall be binding on the Company, the Trustee, the
Remarketing Agent and the Person that submitted such notice.

         4. Each Tender Agent shall be (a) a bank or trust company organized
under the laws of any state of the United States or a national banking

law to perform all the duties imposed upon it by the Eleventh Supplemental
Indenture and shall be acceptable to each Rating Agency, as evidenced by written
confirmation from each Rating Agency that the appointment of such Tender Agent
will not result in the reduction or withdrawal of the then current ratings on
the 2002 Series B Bonds. In the event that the 2002 Series B Bonds no longer
shall be a Book-Entry Only 2002 Series B Bond, the Tender Agent shall maintain
an office or agency in New York, New York at which its duties hereunder are to
be performed. The Tender Agent may at any time resign and be discharged of the
duties and obligations created by the Eleventh Supplemental Indenture by giving
at least thirty (30) days' notice to the other Notice Parties. The Tender Agent
may be removed at any time by the Company upon at least seven (7) days' notice
to the other Notice Parties and the Holders of the 2002 Series B Bonds, other
than 2002 Series B Bonds then in the Fixed Mode. Prior to the 2002 Series B
Bonds being converted to the Auction Mode or the Fixed Mode, no such resignation
or removal shall take effect until the appointment of, and the acceptance of
such appointment by, a successor Tender Agent. Successor Tender Agents may be
appointed from time to time by the Company with the written approval of the Bond
Insurer and the Agent Bank. Upon the resignation or removal of the Tender Agent,
the Tender Agent shall deliver any 2002 Series B Bonds (or beneficial ownership
interests therein) and moneys held by it in such capacity to its successor.

                                       40


         5. The Tender Agent, upon receipt of any notice, Indenture, request,
consent, order, certificate, report, opinion, bond, or other paper or document
furnished to it pursuant to any provision of the Eleventh Supplemental
Indenture, shall examine such instrument to determine whether it conforms to the
requirements of the Eleventh Supplemental Indenture and shall be protected in
acting upon any such instrument believed by it to be genuine and to have been
signed or presented by the proper party or parties. The Tender Agent may consult
with counsel, who may or may not be of counsel to the Company, and the opinion
of such counsel shall be full and complete authorization and protection in
respect of any action taken or suffered by it under the Eleventh Supplemental
Indenture in good faith and in accordance therewith.

         6. Whenever the Tender Agent shall deem it necessary or desirable that
a matter be proved or established prior to taking or suffering any action under
the Eleventh Supplemental Indenture, such matter (unless other evidence in
respect thereof be therein specifically prescribed) may be deemed to be
conclusively proved and established by a certificate of an Officer of the
Company, and such certificate shall be full warrant for any action taken or
suffered in good faith under the provisions of the Eleventh Supplemental
Indenture upon the faith thereof; but in its discretion the Tender Agent may in
lieu thereof accept other evidence of such fact or may require such further or
additional evidence as to it may seem reasonable.

         7. Except as otherwise expressly provided in the Eleventh Supplemental
Indenture, any request, order, notice or other direction required or permitted
to be furnished pursuant to any provision of the Eleventh Supplemental Indenture
by the Company to the Tender Agent shall be sufficiently executed when the same
is executed in the name of the Company by an Officer of the Company.

         8. In the event that the Tender Agent is required to act pursuant to
the terms of the Eleventh Supplemental Indenture upon the receipt of telephonic
notice, such notice shall be promptly confirmed in writing. If such notice shall
not be so confirmed, the Tender Agent shall be entitled to rely upon such
telephonic notice for all purposes whatsoever.

         9. In purchasing 2002 Series B Bonds (or beneficial ownership interests
therein) hereunder, the Tender Agent shall be acting as a conduit and shall not
be purchasing such 2002 Series B Bonds (or beneficial ownership interests
therein) for its own account.

         10. Upon any change in the Tender Agent, the Company shall furnish to
each Rating Agency the notice provided for in Section 7.05 hereof, but the
failure to provide such notice shall not affect the validity of any change in
the Tender Agent.

                                       41


7.03     The Remarketing Agent

         1. At such time (if any) as the 2002 Series B Bonds shall be converted
to an Interest Mode other than the Auction Mode or the Fixed Mode, the Company
shall appoint the initial Remarketing Agent for the 2002 Series B Bonds, which
appointment shall be made at such time as shall be necessary in order to enable
the Remarketing Agent to perform all duties to be performed by it in connection
with such conversion.

         2. Notwithstanding any other provision of the Indenture or the Eleventh
Supplemental Indenture, the Company may determine to appoint multiple
Remarketing Agents for the 2002 Series B Bonds. In such event, the Company shall
take such actions (including, without limitation, obtaining such additional
CUSIP number(s) for the 2002 Series B Bonds) as shall be necessary to identify
separately the 2002 Series B Bonds (or beneficial ownership interests therein)
to be remarketed by each such Remarketing Agent, and for which each such
Remarketing Agent shall be responsible for determining the 2002 Series B Bond
Rate. In the event multiple Remarketing Agents shall be appointed as aforesaid
(a) any reference herein to "the Remarketing Agent" shall be deemed to refer to
the appropriate Remarketing Agent, or all such Remarketing Agents, as the
context may require and (b) any reference herein to "the Remarketing Agreement"
shall be deemed to refer to the Remarketing Agreement to which the appropriate
Remarketing Agent is a party, or all such Remarketing Agreements, as the context
may require.

         3. Each Remarketing Agent shall accept the duties and obligations
thereof under the Eleventh Supplemental Indenture by execution and delivery of
an agreement with the Company under which such Remarketing Agent will agree,
among other things, to keep such books and records regarding the remarketing of
2002 Series B Bonds (or beneficial ownership interests therein) and determining
the interest rates on the 2002 Series B Bonds as provided herein as shall be
consistent with prudent industry practice and to make such books and records
available for inspection by the other Notice Parties at all reasonable times.

         4. Each Remarketing Agent shall be a member of the National Association
of Securities Dealers, Inc., having a capitalization of at least $50,000,000 and
be authorized by law to perform all the duties imposed upon it by the Eleventh
Supplemental Indenture. Any Remarketing Agent may at any time resign and be
discharged of the duties and obligations created by the Eleventh Supplemental
Indenture by giving at least thirty (30) days' notice to the other Notice
Parties and as otherwise provided in the Remarketing Agreement relating to it.
Any Remarketing Agent may be removed at any time by the Company upon such number
of days' written notice to the other Notice Parties as shall be provided in the
applicable Remarketing Agreement. Prior to the 2002 Series B Bonds being
converted to the Auction Mode or the Fixed Mode, no such removal shall be
effective until a successor Remarketing Agent shall have been appointed and
shall have accepted such appointment. A successor Remarketing Agent may be
appointed from time to time by the Company with the written approval of the Bond
Insurer and the Agent Bank.

                                       42


         5. If a Remarketing Agent resigns or is removed, such Remarketing Agent
shall pay over, assign and deliver any moneys and 2002 Series B Bonds (or
beneficial ownership interests therein) held by it in such capacity, other than
2002 Series B Bonds (or beneficial ownership interests therein) held for its own
account, to its successor. Upon any change in a Remarketing Agent, the Company
shall furnish to each Rating Agency the notice provided for in Section 7.05
hereof, but the failure to provide such notice shall not affect the validity of
any change in a Remarketing Agent.

any Bank and the Remarketing Agent, and their officers, directors, employees and

Series B Bonds (or beneficial ownership interests therein) and may join in any
action which any Holder of the 2002 Series B Bonds may be entitled to take, with
like effect as if it did not act in any capacity hereunder. The Trustee, the
Auction Agent, each Broker-Dealer, the Tender Agent, any Bank and the
Remarketing Agent may in good faith hold any other form of indebtedness of the
