                                   ARTICLE II
                  TERMS AND ISSUANCE OF THE SUBORDINATED NOTES

                  Section 2.1 Issue of Subordinated Notes. A series of
Securities which shall be designated the "  % Subordinated Deferrable Notes due
2004" shall be executed, authenticated and delivered in accordance with the
provisions of, and shall in all respects be subject to, the terms, conditions
and covenants of the Indenture and this Fourth Supplemental Indenture
(including the form of Subordinated Note set forth as Exhibits A and B hereto).
The aggregate principal amount of Subordinated Notes of the series created
hereby which may be authenticated and delivered under the Indenture shall not,
except as permitted by the provisions of the Indenture, exceed $257,731,975. The
Subordinated Notes shall be initially issued in certificated form to the Trust
(the "Initial Subordinated Notes") and shall be substantially in the Form of
Exhibit B attached hereto. The terms of such Subordinated Notes are herein
incorporated by reference and are part of the Fourth Supplemental Indenture.

                  Section 2.2 Maturity. Unless a Tax Event Redemption or Cash
Merger Early Redemption occurs, the entire principal amount of the Subordinated
Notes will mature and become due and payable together with any accrued and
unpaid interest thereon, on August 18, 2004 (the "Maturity Date").

                  Section 2.3 Global Subordinated Notes. If distributed to
holders of Preferred Securities in connection with the involuntary or voluntary
liquidation and dissolution of the Trust:

                  (a) If the Preferred Securities are held in book-entry form,
the Initial Subordinated Notes may be presented to the Trustee by the Property
Trustee in exchange for a Global Security in the form of Exhibit A in an
aggregate principal amount equal to all Outstanding Subordinated Notes (a
"Global Subordinated Note"). The Depositary for the Global Subordinated Note
will be The Depository Trust Company. The Global Subordinated Note will be
registered in the name of the Depositary or its nominee, Cede & Co., and
delivered by the Trustee to the Depositary or a custodian appointed by the
Depositary for crediting to the accounts of its participants pursuant to the
instructions of the Property Trustee. The Company upon any such presentation
shall execute a Global Subordinated Note in such aggregate principal amount and
deliver the same to the Trustee for authentication and delivery in accordance
with the Indenture and this Fourth Supplemental Indenture. Payments on the
Subordinated Notes issued as a Global Subordinated Note will be made to the
Depositary or its nominee.

                  (b) If any Preferred Securities are held in non book-entry
certificated form ("Non Book-Entry Preferred Securities"), the Initial
Subordinated Notes may be presented to the Trustee by the Property Trustee, and
such Non

<PAGE>   8

Book-Entry Preferred Securities will be deemed to represent beneficial
interests in Subordinated Notes presented to the Trustee by the Property
Trustee having an aggregate principal amount equal to the aggregate liquidation
amount of the Non Book-Entry Preferred Securities until the Preferred Security
Certificates representing such Non Book-Entry Preferred Securities are presented
to the Security Registrar for transfer or reissuance, at which time such
Preferred Security Certificates will be canceled and a Subordinated Note
registered in the name of the holder of the Preferred Security Certificate or
the transferee of the holder of such Preferred Security Certificate, as the case
may be, with an aggregate principal amount equal to the aggregate liquidation
amount of the Preferred Security Certificate canceled will be executed by the
Company and delivered to the Trustee for authentication and delivery in
accordance with the Indenture and this Fourth Supplemental Indenture. On issue
of such Subordinated Notes, Subordinated Notes with an equivalent aggregate
principal amount that were presented by the Property Trustee to the Trustee will
be deemed to have been canceled.

                  Section 2.4 Interest. (a) Each Subordinated Note will bear
interest at the rate of   % per annum from August 22, 2000 until the Purchase
Contract Settlement Date, and at the Reset Rate thereafter, payable quarterly in
arrears on August 18, November 18, February 18 and May 18 of each year,
commencing November 18, 2000 (the "Interest Payment Dates").

                         (b) The Regular Record Dates for the payment of
interest on the Subordinated Notes on any Interest Payment Date, shall be (i) as
long as the Subordinated Notes are represented by a Global Subordinated Note or
the Initial Subordinated Notes, the Business Day preceding each Interest Payment
Date or (ii) if the Subordinated Notes are issued pursuant to Section 2.3(b)
above, the fifteenth Business Day prior to each Interest Payment Date.

                         (c) The interest rate on the Subordinated Notes
outstanding on and after the Remarketing Date will be reset to the Reset Rate.
The Reset Rate will be equal to the rate per annum that results from the
Remarketing, provided that if a Failed Remarketing occurs, the Reset Rate will
be equal to (i) the Two-Year Benchmark Treasury Rate plus (ii) the Applicable
Margin.

                         (d) The amount of interest payable on the Subordinated
Notes for any period will be computed (i) for any full quarterly period on the
basis of a 360-day year of twelve 30-day months and (ii) for any period shorter
than a full quarterly period, on the basis of a 30-day month and, for any period
less than a month, on the basis of the actual number of days elapsed per 30-day
month. In the

<PAGE>   9

event that any date on which interest is payable on the Subordinated Notes is
not a Business Day, then payment of the interest payable on such date will be
made on the next day that is a Business Day (and without interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next calendar year, then such payment will be made on the preceding Business
Day.

                  Section 2.5 Redemption. (a) If a Tax Event occurs and is
continuing, the Company may, at its option and upon not less than 30 nor more
than 60 days' notice to the Holders of the Subordinated Notes, redeem the
Subordinated Notes in whole (but not in part) within 90 days following the
occurrence of such Tax Event, at a price equal to, for each Subordinated Note,
the applicable Redemption Price. The aggregate Redemption Price shall be paid
prior to 12:00 noon, New York City time, on the date of redemption (the "Tax
Event Redemption Date") or such earlier time as the Company determines, provided
that the Company shall have deposited with the Trustee an amount sufficient to
pay the aggregate Redemption Price by 10:00 a.m. on the Tax Event Redemption
Date. Such redemption shall otherwise be in accordance with the provisions of
Article XI of the Indenture.

                         (b) (i) In connection with a Cash Merger Event so long
as the Subordinated Notes are held by the Trust, then the Company shall redeem
Subordinated Notes in an aggregate principal amount equal to the aggregate
liquidation amount of Preferred Securities to be redeemed in a Cash Merger Early
Redemption at a price per Subordinated Note equal to the applicable Redemption
Price (the "Cash Merger Event Redemption Price").

                  (ii) In connection with a Cash Merger Event, in the event the
Trust has been dissolved or liquidated and the Subordinated Notes have been
distributed to Holders other than the Trust, each Holder of Subordinated Notes
shall have the right to require the Company to redeem all or any part (equal to
$25 or an integral multiple thereof) of such Holder's Subordinated Notes
pursuant to the offer described below (the "Cash Merger Event Offer") at an
offer price in cash equal to the applicable Redemption Price had Preferred
Securities been outstanding at the time and a Cash Merger Early Redemption right
been triggered in respect of such Preferred Securities (also, the "Cash Merger
Event Redemption Price").

                  No later than the day of the Cash Merger Event, the Company
shall mail or cause to be mailed a notice of a pending Cash Merger Event to each
Holder (at its last registered address with a copy to the Trustee and the Paying
Agent) offering to repurchase the Subordinated Notes held by such Holder
pursuant to the procedures specified in such notice. The Cash Merger Event Offer
shall remain open

<PAGE>   10

from the time of mailing until at least 5:00 p.m. on the Business Day
immediately preceding the Cash Merger Early Redemption Date (as such term is
defined below). The notice, which shall govern the terms of the Cash Merger
Event Offer, shall contain all instructions and materials necessary to enable
the Holders to tender Subordinated Notes pursuant to the Cash Merger Event Offer
and shall state:

                    (A)  that the Cash Merger Event Offer is being made pursuant
                         to this Section 2.5(b)(ii) and that all Subordinated
                         Notes tendered will be accepted for payment;

                    (B)  the applicable Cash Merger Event Redemption Price and
                         the Cash Merger Early Redemption Date (as such term is
                         defined below in this Section 2.5), which date shall be
                         no earlier than 20 business days from the date such
                         notice is mailed;

                    (C)  that any Subordinated Note not tendered will continue
                         to accrue interest in accordance with the terms of this
                         Fourth Supplemental Indenture and the Indenture;

                    (D)  that, unless the Company defaults in the payment of the
                         applicable Cash Merger Event Redemption Price, all
                         Subordinated Notes accepted for payment pursuant to the
                         Cash Event Merger Offer will cease to accrue interest
                         after the Cash Merger Early Redemption Date;

                    (E)  that Holders electing to have a Subordinated Note
                         purchased pursuant to any Cash Event Merger Offer will
                         be required to surrender the Subordinated Note, with
                         the form entitled "Option of Holder to Elect Purchase"
                         on the reverse of the Subordinated Note completed, to
                         the Company, a depositary, if appointed by the Company,
                         or a Paying Agent at the address specified in the
                         notice prior to the 5:00 p.m. on the Business Day

                    (F)  that Holders will be entitled to withdraw their
                         election if the Company, depositary or Paying Agent, as
                         the case may be, receives, not later than 5:00 p.m. on

                 (G)     that Holders whose Subordinated Notes are being
                         purchased only in part will be issued new Subordinated
                         Notes equal in principal amount to the unpurchased
                         portion of the Subordinated Notes surrendered, which
                         unpurchased portion must be equal to $25 in principal
                         amount or an integral multiple thereof; and

                 (H)     the circumstances and relevant facts regarding such
                         Cash Merger Event and any other information that would
                         be material to a decision as to whether to tender a
                         Subordinated Note pursuant to the Cash Merger Event
                         Offer.

Subordinated Notes so accepted together with an Officers' Certificate stating
the aggregate principal amount of Subordinated Notes or portions thereof being

Subordinated Notes so tendered the Cash Merger Event Redemption Price for each
such Subordinated Note, and the Trustee shall promptly authenticate and mail (or
cause to be transferred by book entry) to each Holder a new Subordinated Note
equal in principal amount to any unpurchased portion of the Subordinated Notes
surrendered, if any; provided that each such new Subordinated Note shall be in a
principal amount of $25 or an integral multiple thereof. The Company shall

practicable after the applicable Cash Merger Event Redemption Date.

                  The Company shall comply with the requirements of Rule 14e-1
under the Exchange Act and any other securities laws and regulations thereunder
to the extent such laws and regulations are applicable in connection with the

                         (c) Except as provided in Sections 2.5(a) and 2.5(b),
the Company will have no right to redeem the Subordinated Notes.

                         (d) The Subordinated Notes will not be subject to a
sinking fund provision.

                  Section 2.6 Events of Default. So long as the Subordinated
Notes are held by the Trust, it shall be an Event of Default with respect to the
Subordinated Notes if the Trust shall have voluntarily or involuntarily
dissolved, wound up its business or otherwise terminated its existence except in
connection with (i) the distribution of the Subordinated Notes held by the Trust
to the holders of the Preferred Securities and Common Securities in liquidation
of their interests in the Trust, (ii) the redemption of all of the outstanding
Preferred Securities and Common Securities or (iii) a consolidation, conversion,

Subordinated Notes are issued in certificated form, the Paying Agent and the

                  Section 2.8 Extension of Interest Payment Period. The Company
shall have the right at any time and from time to time, prior to August 18,
2003, to defer payments of interest by extending the interest payment period of
such Subordinated Notes for a period not exceeding 12 consecutive quarters or
extending beyond o, 2003 (the "Extension Period"), during which Extension Period
no interest shall be due and payable. To the extent permitted by applicable law,
interest, the payment of which has been deferred because of the extension of the
interest payment period pursuant to this Section 2.8, will bear interest thereon
at the rate of o% compounded quarterly for each quarter of the Extension Period
("Compounded Interest"). At the end of the Extension Period, the Company shall
pay all interest accrued and unpaid on the Subordinated Notes and Compounded
Interest (together, "Deferred Interest") that shall be payable to the Holders of
the Subordinated Notes in whose names the Subordinated Notes are registered in
the Security Register on the first Regular Record Date after the end of the
Extension Period. So long as Preferred Securities are outstanding, the Company
shall not (i) declare or pay any dividends or distributions on, or redeem,
purchase, acquire, or make a liquidation payment with respect to, any of the
Company's capital stock (which includes common and preferred stock), (ii) make
any payment of principal, interest or premium, if any, on or repay or repurchase
or redeem any debt securities of the Company that rank paripassu with or junior
in right of payment to the Subordinated Notes or (iii) make any guarantee
payments with respect to any guarantee by the Company of any securities of any

<PAGE>   13

subsidiary of the Company if such guarantee ranks paripassu or junior in right
of payment to the Subordinated Notes (other than in the case of clauses (i),
(ii) and (iii), (a) dividends or distributions in shares of, or options,
warrants or rights to subscribe for or purchase shares of, common stock of the
Company, (b) any declaration of a dividend in connection with the implementation
of a stockholders' rights plan, or the issuance of stock under any such plan in
the future, or the redemption or repurchase of any such rights pursuant thereto,
(c) payments under the Preferred Securities Guarantee Agreement, dated as of
August 22, 2000, by and between the Company, as guarantor, and The Bank of New
York, as guarantee trustee (the "Preferred Securities Guarantee Agreement"), (d)
as a result of a reclassification of the Company's capital stock solely into
shares of one or more classes or series of the Company's capital stock or the
exchange or the conversion of one class or series of the Company's capital stock
for another class or series of the Company's capital stock, (e) the purchase of
fractional interests in shares of the Company's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged and (f) purchases of the Company's common stock in
connection with the satisfaction by the Company of its obligations (including
purchases related to the issuance of such common stock or rights) under any of
the Company's benefit plans for its and its subsidiaries' directors, officers or
employees or any of the Company's dividend reinvestment plans), (x) if at such
time an Event of Default or an "Event of Default," as defined in the Preferred
Securities Guarantee Agreement, shall have occurred and be continuing or (y)
during any Extension Period. Prior to the expiration of any Extension Period,
the Company may further extend such period, provided that such period together
with all such previous and further extensions thereof shall not exceed 12
quarters or extend beyond August 18, 2003. Upon termination of any Extension
Period and the payment of all Deferred Interest then due, the Company may
commence a new Extension Period, subject to the foregoing requirements. No
interest shall be due and payable during an Extension Period except at the end
thereof, but the Company, at its option, may prepay on any Interest Payment Date
all or any portion of the interest accrued during the then elapsed portion of an
Extension Period.

                  Section 2.9 Notice of Extension. The Company shall give
written notice to the Trustee of its election of any Extension Period (or any
further extension thereof) at least five Business Days before the earlier of (i)
the date the interest on the Subordinated Notes would have been payable except
for the election to begin or extend the Extension Period; (ii) the date the
Trustee is required to give notice to any securities exchange or to Holders of
Subordinated Notes of the Record Date or the Interest Payment Date, and (iii)

that rank paripassu with or junior in right of payment to the Subordinated
Notes; or

                         (c) make any guarantee payments with respect to any
guarantee by the Company of any securities of any subsidiary of the Company if
such guarantee ranks paripassu or junior in right of payment to the
Subordinated Notes (other than in the case of clauses (a), (b) and (c), (i)
dividends or distributions in shares of, or options, warrants or rights to
subscribe for or purchase shares of, common stock of the Company, (ii) any

purchases related to the issuance of such common stock or rights) under any of
the Company's benefit plans for its and its subsidiaries' directors, officers or

                  Section 4.2 Additional Covenants Relating to the Trust. For as
long as the Preferred Securities remain outstanding, the Company will:

                         (a) maintain, directly or indirectly, 100% ownership of

<PAGE>   16

                         (d) not take any action that would be reasonably likely

would have received had no such costs or expenses been incurred by or imposed on
the Trust.

                                    ARTICLE V
                      ORIGINAL ISSUE OF SUBORDINATED NOTES

                  Section 5.1 Original Issue of Subordinated Notes. Subordinated
Notes in an aggregate principal amount of up to $257,731,975 may, upon execution
of this Fourth Supplemental Indenture, be executed by the Company and delivered
to the Trustee for authentication, and the Trustee shall thereupon authenticate
and deliver said Subordinated Notes upon receipt of a Company Order for
authentication and delivery, without any further action by the Company.

                                   ARTICLE VI
                    RIGHTS OF HOLDERS OF PREFERRED SECURITIES

                  Section 6.1 Preferred Security Holders' Rights.
Notwithstanding Section 5.6 of the Indenture, if the Property Trustee fails to
enforce its rights under the Subordinated Notes after a holder of Preferred
Securities has made a written request, the holder of Preferred Securities may,
to the fullest extent permitted by law, institute a legal proceeding directly
against the Company to enforce the Property Trustee's rights under the Indenture
without first instituting any legal proceeding against the Property Trustee or
any other Person.

                  Section 6.2 Direct Action. Notwithstanding any other provision
of the Indenture, for as long as any Preferred Securities remain outstanding, to
the fullest extent permitted by law, if an Event of Default has occurred and is
continuing and

<PAGE>   17

such event is attributable to the failure of the Company to pay interest or
principal on the Subordinated Notes on the date such interest or principal is
other wise payable (or in the case of redemption, the redemption date), then a
holder of Preferred Securities may institute a proceeding directly against the
Company (a "Direct Action") to enforce payment to such holder of the principal
or interest on Subordinated Notes having an aggregate principal amount equal to
the aggregate liquidation amount of the Preferred Securities of such holder.

                  Section 6.3 Payments Pursuant to Direct Actions. The Company
will have the right to set off against its obligations to the Trust, as Holder
of the Subordinated Notes, any payment made to a holder of Preferred Securities
in connection with a Direct Action.

                  Section 6.4 Modifications. So long as any Preferred Securities
remain outstanding, (i) no amendment to this Indenture shall be made that
adversely affects the holders of the Preferred Securities in any material
respect, and no termination of this Indenture shall occur, and no waiver of any
Event of Default or compliance with any covenant under this Indenture shall be
effective, without the prior consent of the holders of at least a Majority in
Liquidation Amount (as defined in the Declaration) of the Preferred Securities
then outstanding unless and until the principal of (and premium, if any, on)
the Subordinated Note and all accrued and unpaid interest thereon have been paid
in full, and (ii) no amendment shall be made to this Article VI of this Fourth
Supplemental Indenture that would impair the rights of the holders of the
Preferred Securities without the prior consent of the holders of each Preferred
Security then outstanding unless and until the principal of (and premium, if
any, on) the Subordinated Note and all accrued and unpaid interest thereon have
been paid in full.

                                   ARTICLE VII
                                   REMARKETING

                  Section 7.1 Effectiveness of this Article. Upon a distribution
of the Subordinated Notes upon the liquidation and dissolution of the Trust
which occurs prior to the Remarketing of the Preferred Securities pursuant to
the Declaration, the Subordinated Notes shall be Remarketed in accordance with
the Remarketing procedures of the Declaration where all references in the
Remarketing procedures to Preferred Securities shall be read as references to
the Subordinated Notes, unless the context requires otherwise. Until such a
distribution, or if such distribution occurs after the Remarketing of the
Preferred Securities pursuant to the Declaration, this Article VII will have no
effect.

                                  ARTICLE VIII
                            ACCELERATION OF MATURITY

           Section 8.1 Automatic Acceleration. Notwithstanding Section
5.1 of the Indenture, if an Event of Default with respect to the Subordinated
Notes specified in clauses (e) or (f) of Section 5.1 of the Indenture occurs and
is continuing, the principal of the Subordinated Notes shall become due and
payable immediately, without any declaration, notice or other act on the part of
the Trustee or any holder thereof.

                                   ARTICLE IX

remaining provisions shall not in any way be affected or impaired thereby.

                  Section 9.6 Benefits of Fourth Supplemental Indenture. Nothing
in this Fourth Supplemental Indenture or in the Subordinated Notes, express or
implied, shall give to any Person, other than the parties hereto and their

                  Section 9.7 Governing Law. This Fourth Supplemental Indenture

                  CMS ENERGY CORPORATION, a corporation duly organized and
existing under the laws of Michigan (herein called the "Company", which term
includes any successor corporation under the Indenture hereinafter referred to),
for value received, hereby promises to pay CMS Energy Trust III, or registered
assigns, the principal sum of                         Dollars on August 18,
2004, and to pay interest on said principal sum from August 22, 2000, or from
the most recent Interest Payment Date to which interest has been paid or duly
provided for, quarterly in arrears on August 18, November 18, February 18 and
May 18 of each year (an

<PAGE>   22

"Interest Payment Date") commencing November 18, 2000, at the rate of    % per
annum until August 18, 2003, and at the Reset Rate thereafter, until the
principal hereof shall have become due and payable, and on any overdue principal
and premium, if any, and (without duplication and to the extent that payment of
such interest is enforceable under applicable law) on any overdue installment of
interest at the same rate per annum compounded quarterly. Any deferred interest
shall accrue interest at the rate set forth in the Fourth Supplemental
Indenture. The amount of interest payable for any period will be computed (1)
for any full quarterly period on the basis of a 360-day year of twelve 30-day
months and (2) for any period shorter than a full quarterly period, on the basis
of a 30-day month and, for any period less than a month, on the basis of the
actual number of days elapsed per 30-day month. In the event that any date on
which interest is payable is not a Business Day, then payment of the interest
payable on such date will be made on the next day that is a Business Day (and
without any interest or other payment in respect of such delay), except that, if
such Business Day is in the next calendar year, then such payment will be made
on the preceding Business Day. The interest installment so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in the Indenture, referred to on the reverse side hereof, be paid to
the Holder in whose name this Security (or one or more Predecessor Securities,
as defined in said Indenture) is registered at the close of business on the
Regular Record Date for such interest installment, which, shall be the close of
business on the Business Day preceding such Interest Payment Date. Any such
interest installment not punctually paid or duly provided for shall forthwith
cease to be payable to the Holder on such Regular Record Date, and may be paid
to the Holder in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date to
be fixed by the Trustee referred to on the reverse side hereof for the payment
of such defaulted interest, notice whereof shall be given to the Holders of the
Security not less than 10 days prior to such Special Record Date, or may be paid
at any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Security may be listed, and upon such
notice as may be required by such exchange, all as more fully provided in the
Indenture.

                  Payment of the principal of and premium, if any, and interest
on this Security will be made at the office or agency of the Trustee maintained
for that purpose in such coin or currency of the United States of America that
at the time of payment is legal tender for payment of public and private debts.
The Company may pay principal and interest by check payable in such money mailed
to the Holder's registered address or by wire transfer to a dollar account
designated by the Holder.

                  Interest on the Securities is deferrable in accordance with
the terms of the Fourth Supplemental Indenture.

                  This Security is, to the extent provided in the Indenture, a
subordinated, unsecured obligation of the Company, subject in right to the
prior

<PAGE>   23

payment in full of all Senior Indebtedness (as such term is defined in the
Indenture).

                  Unless the Certificate of Authentication hereon has been
executed by or on behalf of the Trustee, this Security shall not be entitled to
any benefit under the Indenture or be valid or obligatory for any purpose. The
provisions of this Security are continued on the reverse side hereof, and such
continued provisions shall for all purposes have the same effect as though fully
set forth at this place.

which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the
Securities and the terms upon which the Securities are, and are to be,
authenticated and delivered. This Security is one of the series designated on
the face hereof, limited in aggregate principal amount to $           .

                  All terms used in this Security that are defined in the

                  This Security is not subject to any sinking fund, nor may this
Security be redeemed at the option of the Company prior to the Maturity Date
except upon the occurrence of a Tax Event as described below.

                  The Indenture contains provisions for defeasance at any time
of the entire indebtedness of this Security upon compliance by the Company with
certain conditions set forth therein.

                  If an Event of Default with respect to Securities of this
series shall occur and be continuing, the principal of the Securities of this
series may be declared due and payable in the manner and with the effect
provided in the Indenture.

                  If a Tax Event occurs and is continuing, the Company may, at

each series to be affected under the Indenture at any time by the Company and

their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of
this Security and of any Security issued upon the registration of transfer
hereof or in exchange hereof or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.

in the names of Persons other than the Depositary with respect to such series or
its nominee only as provided in this paragraph. This Security shall be so
exchangeable if (x) the Depositary is at any time unwilling or unable to
continue as Depositary for such series, (y) the Company executes and delivers to
the Trustee a Company Order providing that this Security shall be so
exchangeable or (z) there shall have occurred and be continuing an Event of
Default with respect to the Securities of such series. Securities so issued in
exchange for this Security shall be of the same series, having the same interest
rate, if any, and maturity and having the same terms as this Security, in
authorized denominations and in the aggregate having the same principal amount
as this Security and registered in such names as the Depositary for such Global
Security shall direct.

limitations therein set forth, the transfer of a Security of the series of which
this Security is a part is registrable in the Security Register, upon surrender

Company in any place where the principal of and premium, if any, and interest,
if any, on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his

<PAGE>   27

attorney duly authorized in writing, and thereupon one or more new Securities of
this series, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.

are issuable only in registered form without coupons in denominations of $25 and

transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Holder in whose name this Security is registered as the owner

affected (voting as a class). The Indenture also contains provisions permitting
the Holders of a majority in aggregate principal amount of the Outstanding
Securities of each series at the time, on behalf of the Holders of all
Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of
this Security and of any Security issued upon the registration of transfer
hereof or in exchange hereof or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and
premium, if any, and interest, if any, on this Security at the times, place and
rate, and in the coin or currency, herein prescribed.

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of a Security of the series of which
this Security is a part is registrable in the Security Register, upon surrender
of this Security for registration of transfer at the office or agency of the
Company in any place where the principal of and premium, if any, and interest,
if any, on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series,
of authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.

                  The Securities of the series of which this Security is a part
are issuable only in registered form without coupons in denominations of $25 and
in integral multiples thereof. As provided in the Indenture and subject to
certain limitations therein set forth, Securities of this series are
exchangeable for a like aggregate principal amount of Securities of this series
and of like tenor of a different authorized denomination, as requested by the
Holder surrendering the same.

                  No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

("Declaration"), dated as of August 22, 2000, by and among CMS Energy Corpora-
tion, a Michigan corporation, including any successors or assigns, as Sponsor,
Alan M. Wright, an individual, and Thomas A. McNish, an individual, as the

         WHEREAS, certain of the Trustees and the Sponsor established CMS Energy
Trust III (the "Trust"), a business trust under the Business Trust Act, pursuant
to a Declaration of Trust dated as of December 10, 1998, (the "Original

the Secretary of State of the State of Delaware on December 10, 1998; and

         WHEREAS, the sole purpose of the Trust shall be to sell and issue
certain securities representing undivided beneficial interests in the assets of
the Trust, to invest the proceeds from such sales in the Subordinated Deferrable
Notes issued by the Subordinated Deferrable Notes Issuer and to engage in only
those activities necessary or incidental thereto; and

         WHEREAS, the parties hereto, by this Declaration, amend and restate
each and every term and provision of the Original Declaration.

         NOW, THEREFORE, it being the intention of the parties hereto to
continue the Trust as a business trust under the Business Trust Act and that
this Declaration constitute the governing instrument of such business trust, the
trustees hereby declare that all assets contributed to the Trust be held in
trust for the benefit of the Holders, from time to time, of the Securities
representing undivided beneficial interests in the assets of the Trust issued
hereunder, subject to the provisions of this Declaration.

notes of the Company are rated by only one rating agency on or before the
Remarketing Date, the prevailing rating shall at all times be determined without
reference to the rating of any other rating agency; provided that if no such
rating agency shall have in effect a rating for the subordinated notes of the

agency or rating agencies, as required above, the prevailing rating shall be
Below BBB/ "baa."

             (ii) requires the vote or consent of the holders of greater than a
         majority in principal amount of the Subordinated Deferrable Notes (a
         "Supermajority") to be waived under the Indenture, the related Trust
         Enforcement Event under this Declaration only may be waived by the
         vote or written consent of the Holders of at least the same
         Supermajority in aggregate stated liquidation amount of the Preferred
         Securities outstanding.

The foregoing provisions of this Section 2.6 shall be in lieu of Section
316(a)(1)(B) of the Trust Indenture Act, and Section 316(a)(1)(B) of the Trust
Indenture Act is hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act. Upon such waiver, any such
Trust Enforcement Event in respect of the Preferred Securities shall be deemed
to have been cured for every purpose of this Declaration and the Preferred
Securities, but no such waiver shall extend to any subsequent or other Trust
Enforcement Event with respect to the Preferred Securities or impair any right
consequent thereon. Any waiver by the Holders of the Preferred Securities of a
Trust Enforcement Event with respect to the Preferred Securities also shall be
deemed to constitute a waiver by the Holders of the Common Securities of any
such Trust Enforcement Event with respect to the Common Securities for all
purposes of this Declaration without any further act, vote or consent of the
Holders of the Common Securities.

         (b) The Holders of the Common Securities may waive, by vote or written
consent, any past Trust Enforcement Event in respect of the Common Securities
and its consequences, provided that if the underlying Indenture Event of Default
is not waivable under the Indenture, then, except where the Holders of the
Common Securities have been deemed to have waived such Trust Enforcement as
provided below in this Section 2.6(b), the related Trust Enforcement Event under
this Declaration also shall not be waivable. The Holders of the Common
Securities shall be deemed to have waived any and all Trust Enforcement Events
in respect of the Common Securities and the consequences thereof until all Trust
Enforcement Events in respect of the Preferred Securities have been cured,
waived or otherwise eliminated. Until all Trust Enforcement Events in respect
of the Preferred Securities have been so cured, waived or otherwise eliminated,
the Property Trustee shall be deemed to be acting solely on behalf of the
Holders of the Preferred Securities, and only the Holders of the Preferred
Securities shall have the right to direct the Property Trustee. The foregoing
provisions of this Section 2.6(b) shall be in lieu of Sections 316(a)(1)(A) and
316(a)(1)(B) of the Trust Indenture Act, and Sections 316(a)(1)(A) and
316(a)(1)(B) of the Trust Indenture Act are hereby expressly excluded from this

<PAGE>   24

Declaration and the Securities, as permitted by the Trust Indenture Act. Subject
to the foregoing provisions of this Section 2.6(b), upon such cure, waiver or
other elimination, any Trust Enforcement Event in respect of the Common
Securities shall be deemed to have been cured for every purpose of this
Declaration and the Common Securities, but no such waiver shall extend to any
subsequent or other Trust Enforcement Event with respect to the Common
Securities or impair any right consequent thereon.

         (c) A waiver of an Indenture Event of Default under the Indenture by
the Property Trustee at the direction of the Holders of the Preferred Securities
shall constitute a waiver of the corresponding Trust Enforcement Event under
this Declaration. Any such waiver by the Holders of the Preferred Securities
also shall be deemed to constitute a waiver by the Holders of the Common
Securities of any such Trust Enforcement Event with respect to the Common
Securities for all purposes of this Declaration without any further act, vote or
consent of the Holders of the Common Securities. The foregoing provisions of
this Section 2.6(c) shall be in lieu of Section 316(a)(1)(B) of the Trust
Indenture Act, and Section 316(a)(1)(B) of the Trust Indenture Act is hereby
expressly excluded from this Declaration and the Securities, as permitted by the
Trust Indenture Act.

         Section 2.7    Trust Enforcement Event; Notice.

         (a) Within 90 days after the occurrence of a Trust Enforcement Event
actually known to a Responsible Officer of the Property Trustee, the Property
Trustee shall transmit by mail, first class postage prepaid, to the Holders of
the Securities, notice of such Trust Enforcement Event, unless such Trust
Enforcement Event has been cured before the giving of such notice; provided
that, except for a default in the payment of principal of (or premium, if any)
or interest on any of the Subordinated Deferrable Notes, the Property Trustee
shall be protected in withholding such notice if and so long as a Responsible
Officer of the Property Trustee in good faith determines that the withholding of
such notice is in the interests of the Holders of the Securities.

         (b) The Property Trustee shall not be deemed to have knowledge of any
Trust Enforcement Event except for:

             (i)   a default under Section 501(1) and (2) of the Indenture; or

             (ii)  any default as to which the Property Trustee shall have
         received written notice or of which a Responsible Officer of the
         Property Trustee charged with the administration of this Declaration
         shall have actual knowledge.

             (i)    invest any proceeds received by the Trust in connection with
         its ownership of the Subordinated Deferrable Notes, but the Property

             (ii)   acquire any assets other than as expressly provided herein;

         (D) consent to any amendment, modification or termination of the
         Indenture or the Subordinated Deferrable Notes where such consent is
         required, unless the Trust has received an opinion of counsel to the
         effect that such modification will not cause more than an insubstantial
         increase in the risk that the Trust will not be classified as a grantor
         trust for United States federal income tax purposes;

             (ix)   take any action inconsistent with the status of the Trust as

         securities exchange or automated quotation system) that does not
         expressly provide that the Holders of Preferred Securities, in their
         capacities as such, have limited liability (in accordance with the
         provisions of the Business Trust Act) for the liabilities and
         obligations of the Trust, which express provision shall be in
         substantially the following form:

             The Holders of the Preferred Securities, in their capacities as
             such, shall not be personally liable for any liabilities or
             obligations of the Trust arising out of this Agreement, and the
             parties hereto hereby agree that the Holders of the Preferred
             Securities, in their capacities as such, shall be entitled to the
             same limitation of personal liability extended to stockholders of
             private corporations for profit organized under the General
             Corporation Law of the State of Delaware.

         Section 3.8    Powers and Duties of the Property Trustee.

         (a) The legal title to the Subordinated Deferrable Notes shall be owned
by and held of record in the name of the Property Trustee in trust for the
benefit of the Trust and the Holders of the Securities. The right, title and
interest of the Property Trustee to the Subordinated Deferrable Notes shall vest
automatically in each Person that hereafter may be appointed as Property Trustee

Deferrable Notes have been executed and delivered.

         (b) The Property Trustee shall not transfer its right, title and
interest in the Subordinated Deferrable Notes to the Regular Trustees nor to the
Delaware Trustee (if the Property Trustee does not also act as Delaware
Trustee).

         (c) The Property Trustee shall:

             (i) establish and maintain a segregated non-interest bearing trust
         account (the "Property Account") in the name of and under the exclusive
         control of the Property Trustee on behalf of the Holders of the
         Securities and, upon the receipt of payments of funds made in respect
         of the Subordinated Deferrable Notes, deposit such funds into the
         Property Account and make payments to the Holders of the Securities
         from the Property Account in accordance with Section 7.2. Funds in the
         Property Account shall be held uninvested until disbursed in accordance
         with this Declaration. The Property Account shall be an account that is
         maintained with a banking institution, the rating on whose long-term
         unsecured indebtedness is at least equal to the rating assigned to the
         Company's subordinated notes by a "nationally recognized statistical
         rating organization" within the meaning of Rule 436(g)(2) under the
         Securities Act;

             (ii)   engage in such ministerial activities as shall be necessary
         or appropriate to effect the redemption of the Securities to the extent
         the Subor dinated Deferrable Notes are redeemed or mature;

             (iii)  upon written direction by the Sponsor to dissolve the Trust,
         to engage in such ministerial activities as shall be necessary or
         appropriate to effect the distribution of the Subordinated Deferrable
         Notes to the Holders of the Securities in exchange for the Securities;
         and

             (iv)   be a United States Person.

         (d) The Property Trustee shall take all actions and perform such duties
as may be specifically required of the Property Trustee pursuant to the terms of
this Declaration and the Securities.

         (e) The Property Trustee shall take any Legal Action that arises out of
or in connection with (i) a Trust Enforcement Event of which a Responsible
Officer of the Property Trustee has actual knowledge or (ii) the Property
Trustee's duties and obligations under this Declaration or the Trust Indenture
Act; provided that if a Trust Enforcement Event has occurred and is continuing
and such event is attributable to the failure of the Subordinated Deferrable
Notes Issuer to make payments on the Subordinated Deferrable Notes on the date
such interest or principal is otherwise
<PAGE>   32

Section 3.3, and the Property Trustee shall have no power to, and shall not,
take any action that is inconsistent with the purposes and functions of the
Trust set out in Section 3.3.

         Section 3.9 Certain Duties and Responsibilities of the Property
Trustee.

         (a) The Property Trustee, before the occurrence of any Trust
Enforcement Event and after the cure or waiver of all Trust Enforcement Events
that may have occurred, shall undertake to perform only such duties as are
specifically set forth in this Declaration, and no implied covenants shall be
read into this Declaration against the Property Trustee. If a Trust Enforcement
Event has occurred (that has not been cured or waived pursuant to Section 2.6)
of which a Responsible Officer of the Property Trustee has actual knowledge, the
Property Trustee shall exercise such of the rights and powers vested in it by
this Declaration and shall use the same degree of care and skill in its exercise
as a prudent person would exercise or use under the circumstances in the conduct
of his or her own affairs.

         (b) No provision of this Declaration shall be construed to relieve the
Property Trustee from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct, except that:

                  (i) prior to the occurrence of a Trust Enforcement Event and
         after the cure or waiver of all such Trust Enforcement Events that may
         have occurred:

                           (A) the duties and obligations of the Property
                  Trustee shall be determined solely by the express provisions
                  of this Declaration, and the Property Trustee shall not be
                  liable except for the performance of such duties and
                  obligations as are specifically set forth in this Declaration,
                  and no implied covenants or obligations shall be read into
                  this Declaration against the Property Trustee; and

                           (B) in the absence of bad faith on the part of the
                  Property Trustee, the Property Trustee may conclusively rely,
                  as to the truth of the statements and the correctness of the
                  opinions expressed therein, upon any certificates or opinions
                  furnished to the Property Trustee and conforming to the
                  requirements of this Declaration; but in the case of any such
                  certificates or opinions that by any provision hereof are
                  specifically required to be furnished to the Property
                  Trustee, the Property Trustee shall be under a duty to examine
                  such certificates or

<PAGE>   33

                  opinions to determine whether or not they conform to the
                  requirements of this Declaration (but need not confirm or
                  investigate the accuracy of mathematical calculations or
                  other facts stated therein);

                  (ii) the Property Trustee shall not be liable for any error of
         judgment made in good faith by a Responsible Officer of the Property
         Trustee, unless it has been proven that the Property Trustee was
         negligent in ascertaining the pertinent facts;

                  (iii) the Property Trustee shall not be liable with respect to
         any action taken or omitted to be taken by it without negligence, in
         good faith in accordance with the direction of the Holders of not less
         than a Majority in Liquidation Amount of the Securities relating to the
         time, method and place of conducting any proceeding for any remedy
         available to the Property Trustee, or exercising any trust or power
         conferred upon the Property Trustee under this Declaration;

                  (iv) no provision of this Declaration shall require the
         Property Trustee to expend or risk its own funds or otherwise incur
         personal financial liability in the performance of any of its duties or
         in the exercise of any of its rights or powers, if it has reasonable
         grounds for believing that the repayment of such funds or liability is
         not reasonably assured to it under the terms of this Declaration or
         indemnity reasonably satisfactory to the Property Trustee against such
         risk or liability is not reasonably assured to it;

                  (v) the Property Trustee's sole duty with respect to the
         custody, safe-keeping and physical preservation of the Subordinated
         Deferrable Notes and the Property Account shall be to deal with such
         property in a similar manner as the Property Trustee deals with similar
         property for its own account, subject to the protections and
         limitations on liability afforded to the Property Trustee under this
         Declaration and the Trust Indenture Act;

                  (vi) the Property Trustee shall have no duty or liability for
         or with respect to the value, genuineness, existence or sufficiency of
         the Subordi nated Deferrable Notes or the payment of any taxes or
         assessments levied thereon or in connection therewith;

                  (vii) the Property Trustee shall not be liable for any

         Section 3.10 Certain Rights of Property Trustee.

         (a) Subject to the provisions of Section 3.9:

                  (i) The Property Trustee may conclusively rely and shall be
         fully protected in acting or refraining from acting upon any
         resolution, certificate, statement, instrument, opinion, report,
         notice, request, direction, consent, order, bond, debenture, note,
         other evidence of indebtedness or other paper or document believed by
         it to be genuine and to have been signed, sent or presented by the
         proper party or parties.

                  (ii) Any direction or act of the Sponsor contemplated by this
         Declaration shall be sufficiently evidenced by an Officers'
         Certificate.

                  (iii) Whenever in the administration of this Declaration, the
         Property Trustee shall deem it desirable that a matter be proved or
         established before taking, suffering or omitting any action hereunder,
         the Property Trustee (unless other evidence is herein specifically
         prescribed) may request, in the absence of bad faith on its part, and
         conclusively rely upon an Officers' Certificate which, upon receipt of
         such request, shall be promptly delivered by the Sponsor.

                  (iv) The Property Trustee shall have no duty to see to any
         recording, filing or registration of any instrument (including any
         financing or continuation statement or any filing under tax or
         securities laws) or any rerecording, refiling or registration thereof.

                  (v) The Property Trustee may consult with counsel of its
         choice or other experts, and the advice or opinion of such counsel and
         experts with respect to legal matters or advice within the scope of
         such experts' area of expertise shall be full and complete
         authorization and protection in respect of any action taken, suffered
         or omitted by it hereunder in good faith and in accordance with such
         advice or opinion. Such counsel may be counsel to the Sponsor or any of
         its Affiliates and may include any of its employees. The

<PAGE>   35

         Property Trustee shall have the right at any time to seek instructions
         concerning the administration of this Declaration from any court of
         competent jurisdiction.

                  (vi) The Property Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this Declaration
         at the request or direction of any Holder of Securities, unless such
         Holder of Securities has provided to the Property Trustee security and
         indemnity, reasonably satisfactory to the Property Trustee, against
         the costs, expenses (including attorneys' fees and expenses and the
         expenses of the Property Trustee's agents, nominees or custodians) and
         liabilities that might be incurred by it in complying with such request
         or direction, including such reasonable advances as may be requested by
         the Property Trustee; provided that nothing contained in this Section
         3.10(a) shall be taken to relieve the Property Trustee, upon the
         occurrence of an Indenture Event of Default, of its obligation to
         exercise the rights and powers vested in it by this Declaration.

                  (vii) The Property Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document, but the Property Trustee, in
         its discretion, may make such further inquiry or investigation into
         such facts or matters as it sees fit, and, if the Trustee shall
         determine to make such further inquiry or investigation, it shall be
         entitled to examine the books, records and premises of the Sponsor,
         personally or by agent or attorney at the sole cost of the Sponsor and
         shall incur no liability or additional liability of any kind by reason
         of such inquiry or investigation.

                  (viii) The Property Trustee may execute any of the trusts or
         powers hereunder or perform any duties hereunder either directly or by
         or through agents, custodians, nominees or attorneys, provided that any
         such action (other than ministerial action) executed or performed by
         such agent or attorney is executed or performed by an agent or an
         attorney that is a United States Person, and the Property Trustee shall
         not be responsible for any misconduct or negligence on the part of any
         agent or attorney appointed with due care by it hereunder.

                  (ix) Any action taken by the Property Trustee or its agents
         hereunder shall bind the Trust and the Holders of the Securities, and
         the

<PAGE>   36

         signature of the Property Trustee or its agents alone shall be
         sufficient and effective to perform any such action, and no third
         party shall be required to inquire as to the authority of the Property
         Trustee to so act or as to its compliance with any of the terms and
         provisions of this Declaration, both of which shall be evidenced
         conclusively by the Property Trustee's or its agent's taking such
         action.

                  (x) Whenever in the administration of this Declaration the
         Property Trustee shall deem it desirable to receive instructions with
         respect to enforcing any remedy or right or taking any other action
         hereunder, the Property Trustee (A) may request instructions from the
         Holders of the Securities, which instructions only may be given by the
         Holders of the same proportion in liquidation amount of the Securities
         as would be entitled to direct the Property Trustee under this
         Declaration in respect of such remedy, right or action, (B) may refrain
         from enforcing such remedy or right or taking such other action until
         such instructions are received and (C) shall be protected in
         conclusively relying on or acting in accordance with such instructions.

                  (xi) Except as otherwise expressly provided by this
         Declaration, the Property Trustee shall not be under any obligation to
         take any action that is discretionary under the provisions of this
         Declaration.

                  (xii) The Property Trustee shall not be liable for any action
         taken, suffered or omitted to be taken by it without negligence, in
         good faith and reasonably believed by it to be authorized or within the
         discretion, rights or powers conferred upon it by this Declaration.

                  (xiii) the Property Trustee shall not be deemed to have notice
         of any Indenture Event of Default or Trust Enforcement Event unless a
         Responsible Officer of the Property Trustee has actual knowledge
         thereof or unless written notice of any event which is in fact such a
         default is received by the Property Trustee at the Corporate Trust
         Office of the Property Trustee, and such notice references the Trust
         Preferred Securities and this Declaration.

         (b) No provision of this Declaration shall be deemed to impose any duty
or obligation on the Property Trustee to perform any act or acts or exercise any
right, power, duty or obligation conferred or imposed on it, in any jurisdiction
in which it shall be illegal, or in which the Property Trustee shall be
unqualified or incompetent in accordance with applicable law, to perform any
such act or acts, or to exercise any such right, power, duty or obligation. No
permissive power or authority available to

<PAGE>   37

the Property Trustee shall be construed to be a duty.

         Section 3.11 Delaware Trustee.

                  Notwithstanding any other provision of this Declaration other
than Section 6.2, the Delaware Trustee shall not be entitled to exercise any
powers of, nor shall the Delaware Trustee have any of the duties and
responsibilities of, the trustees described in this Declaration. Except as set
forth in Section 6.2, the Delaware Trustee shall be a Trustee for the sole and
limited purpose of fulfilling the require ments of Section 3807(a) of the
Business Trust Act and shall be a United States Person. If the Property Trustee,
meeting the requirements of Section 6.2, also acts as Delaware Trustee, this
Section 3.11 shall not apply.

         Section 3.12 Execution of Documents.

                  Except as otherwise required by the Business Trust Act or
applicable law, any Regular Trustee is authorized to execute on behalf of the

         Section 3.13 Not Responsible for Recitals or Issuance of Securities.

                  The recitals contained in this Declaration and the Securities
shall be taken as the statements of the Sponsor, and the Trustees do not assume
any responsibility for their correctness. The Trustees make no representations
as to the value or condition of the property of the Trust or any part thereof.
The Trustees make no representations as to the validity or sufficiency of this
Declaration, the Securities, the Subordinated Deferrable Notes or the Indenture.

         Section 3.14 Duration of Trust.

                  The Trust shall exist until dissolved pursuant to the
provisions of Article 8 hereof.

         Section 3.15 Mergers.

         (a) The Trust may not consolidate with, convert into, amalgamate or
merge with or into, be replaced by or convey, transfer or lease its properties
and assets substantially as an entirety to any corporation or other body, except
as described in Section 3.15(b) and (c) or Section 8.2.

         (b) At the request of the Sponsor and with the consent of the Regular
Trustees or, if there are more than two, a majority of the Regular Trustees and
without the consent of the Holders of the Preferred Securities, the Delaware
Trustee

<PAGE>   38

or the Property Trustee, the Trust may consolidate with, convert into,
amalgamate or merge with or into, be replaced by or convey, transfer or lease
its properties substantially as an entirety to a trust organized as such under
the laws of any state; provided that:

                  (i) if the Trust is not the successor entity, such successor
         entity (the "Successor Entity") either:

                           (A)  expressly assumes all of the obligations of the
                                Trust with respect to the Securities; or

                           (B)  substitutes for the Securities other securities
                                having substantially the same terms as the
                                Securities (the "Successor Securities"), so
                                long as such Successor Securities rank the same
                                as the Securities with respect to Distributions
                                and payments upon liquidation, redemption and
                                otherwise;

                  (ii) the Subordinated Deferrable Notes Issuer expressly
         appoints a trustee of such Successor Entity that possesses the same
         powers and duties as the Property Trustee as the holder of the
         Subordinated Deferrable Notes;

                  (iii) the Preferred Securities or any Successor Securities are
         or, upon notification of issuance will be, listed on any national
         securities ex change or with any other organization on which the
         Preferred Securities are then listed or quoted;

                  (iv) such consolidation, conversion, amalgamation, merger,
         replacement, conveyance, transfer or lease does not cause the Preferred
         Securities (including any Successor Securities) to be downgraded by any
         nationally recognized statistical rating organization;

                  (v) such consolidation, conversion, amalgamation, merger,
         replacement, conveyance, transfer or lease does not adversely affect
         the rights, preferences and privileges of the Holders of the Preferred
         Securities (including any Successor Securities) in any material
         respect;

                  (vi) such Successor Entity has a purpose substantially
         identical to that of the Trust;

<PAGE>   39

                  (vii) prior to such consolidation, conversion, amalgamation,
         merger, replacement, conveyance, transfer or lease, the Sponsor has
         received an opinion of independent counsel to the Trust experienced in
         such matters to the effect that:

                           (A)  such consolidation, conversion, amalgamation,
                                merger, replacement, conveyance, transfer or
                                lease does not adversely affect the rights,
                                preferences and privileges of the Holders of the
                                Securities (including any Successor Securities)
                                in any material respect;

                           (B)  following such consolidation, conversion,
                                amalgamation, merger, replacement, conveyance,
                                transfer or lease, neither the Trust nor such
                                Successor Entity will be required to register as
                                an Investment Company under the Investment
                                Company Act; and

                           (C)  following such consolidation, conversion,
                                amalgamation or merger, replacement,
                                conveyance, transfer or lease, the Trust (or
                                such Successor Entity) will continue to be
                                classified as a grantor trust for United
                                States federal income tax purposes;

                  (viii) the Sponsor or any permitted successor or assignee owns
         all of the common securities of such Successor Entity and guarantees
         the obligations of such Successor Entity under the Successor
         Securities, at least to the extent provided by the Guarantee; and

                  (ix) such Successor Entity expressly assumes all of the
         obligations of the Trust.

         (c) Notwithstanding Section 3.15(b), the Trust shall not, except with
the consent of Holders of 100% in aggregate liquidation amount of the
Securities, consolidate with, convert into, amalgamate or merge with or into, be
replaced by or convey, transfer or lease its properties and assets substantially
as an entirety to, any other entity or permit any other entity to consolidate
with, amalgamate, merge with or into, or replace it, if such consolidation,
conversion, amalgamation, merger, replacement, conveyance, transfer or lease
would cause the Trust or any successor Entity to be classified as other than a
grantor trust for United States federal income tax purposes or would cause each
Holder of Securities not to be treated as owning an undivided beneficial
ownership interest in the Subordinated Deferrable Notes.

         Section 3.16 Compensation and Reimbursement.

                  The Sponsor agrees to pay each of the Trustees from time to
time such compensation for all services rendered by such Trustee hereunder as
the Sponsor and such Trustee may agree upon from time to time (which
compensation shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust). To the fullest extent permitted
by law the parties intend that Section 3561 of Title 12 of the Delaware Code
shall not apply to the Trust and that compensation paid pursuant to this
Section 3.16 not be subject to review by any court under Section 3560 of Title
12 of the Delaware Code.

         Section 3.17 Property Trustee May File Proofs of Claim.

                  In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other similar judicial proceeding relative to the Trust or any other obligor
upon the Securities or the property of the Trust or of such other obligor or
their creditors, the Property Trustee (irrespective of whether any Distributions
on the Securities are then due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Property Trustee has
made any demand on the Trust for the payment of any past due Distributions)
shall be entitled and empowered, to the fullest extent permitted by law, by
intervention in such proceeding or otherwise:

         (a) to file and prove a claim for the whole amount of any Distributions
owing and unpaid in respect of the Securities (or, if the Securities are
original issue discount securities, such portion of the liquidation amount as
may be specified in the terms of such securities) and to file such other papers
or documents as may be necessary or advisable in order to have the claims of the
Property Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Property Trustee, its agents and counsel) and
of the Holders of the Securities allowed in such judicial proceeding; and

         (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder of Securities to make such payments to the Property Trustee and, in
the event the Property Trustee consents to the making of such payments directly
to the Holders, to pay to the Property Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Property
Trustee, its agents and counsel, and any other amounts due the Property Trustee.

<PAGE>   41

         Nothing herein contained shall be deemed to authorize the Property
Trustee to authorize or consent to or accept or adopt, on behalf of any Holder
of Securities, any plan of reorganization, arrangement, adjustment or
compensation affecting the Securities or the rights of any Holder thereof or to
authorize the Property Trustee to vote in respect of the claim of any Holder of
Securities in any such proceeding.

         Section 5.1 Subordinated Deferrable Notes Issuer's Purchase of the
Common Securities.

                  On the Closing Date, the Subordinated Deferrable Notes Issuer
shall purchase all of the Common Securities issued by the Trust, in an aggregate
liquidation amount equal to at least three percent of the total capital of the
Trust, at such time as the Preferred Securities are sold and issued. If any
additional Preferred Securities are issued pursuant to the exercise of any
Over-allotment Option, then the Subordinated Deferrable Notes Issuer shall
purchase, on the date of such issuance, an amount of

<PAGE>   44

additional Common Securities such that the aggregate number of Common
Securities held by the Subordinated Deferrable Notes Issuer, upon such purchase,
will equal at least three percent of the total capital of the Trust.

                  The aggregate stated liquidation amount of the Common
Securities outstanding at any time shall not be less than three percent of the
total capital of the Trust.

         Section 5.2 Covenants of the Subordinated Deferrable Notes Issuer.

                  For so long as the Preferred Securities remain outstanding,
the Subordinated Deferrable Notes Issuer shall covenant (i) to maintain,
directly or indirectly, 100% ownership of the Common Securities, (ii) to cause
the Trust to remain a statutory business trust and not to voluntarily dissolve,
wind up, liquidate or be terminated, except as permitted by this Declaration,
(iii) to use its commercially reasonable efforts to ensure that the Trust will
not be an Investment Company required to be registered under the Investment
Company Act and (iv) not to take any action that would be reasonably likely to
cause the Trust to be classified as an association or a publicly traded
partnership taxable as a corporation for United States federal income tax
purposes.

         Section 5.3 Holder of the Common Securities.

                  Each Holder of the Common Securities shall at all times hold
the Common Securities in its individual capacity on its own behalf and shall
not, in its capacity as a Holder of the Common Securities, be under (or subject
to) the control or direction of any Foreign Person (pursuant to a contractual
arrangement or other wise) other than by virtue of such Foreign Person's direct
or indirect stock owner ship, if any, of the Holder of Common Securities.
Notwithstanding anything in this Declaration to the contrary, each Holder of the
Common Securities shall at all times be a United States Person and shall be
authorized to give any direction hereunder with respect to the Trust as shall be
necessary for the Trust not to be considered a foreign trust for United States
Federal income tax purposes.

         Section 5.4 Exchanges.

         (a) If at any time the Subordinated Deferrable Notes Issuer or any of
its Affiliates (in either case, a "Issuer Affiliated Holder") is the Holder of
any Preferred Securities, such Issuer Affiliated Holder shall have the right to
deliver to the Property Trustee all or such portion of its Preferred Securities
as it elects and receive, in exchange therefor, Subordinated Deferrable Notes in
an aggregate principal amount equal to the aggregate stated liquidation amount
of, with an interest rate identical to the distribution rate of, and accrued and
unpaid interest equal to accumulated and unpaid Distributions on, such Preferred
Securities. Such election (i) shall be

<PAGE>   45

exercisable effective on any Distribution payment date by such Issuer
Affiliated Holder delivering to the Property Trustee a written notice of such
election specifying the aggregate liquidation amount of the Preferred Securities
with respect to which such election is being made and the Distribution payment
date on which such exchange shall occur, which Distribution payment date shall
be not less than ten Business Days after the date of receipt by the Property
Trustee of such election notice and (ii) shall be conditioned upon such Issuer
Affiliated Holder having delivered or caused to be delivered to the Property
Trustee or its designee the Preferred Securities which are the subject of such
election by 10:00 A.M. New York time, on the Distribution payment date on which
such exchange is to occur. After the exchange, such Preferred Securities will
be canceled and will no longer be deemed to be outstanding and all rights of the
Subordinated Deferrable Notes Issuer or its Affiliate(s) with respect to such
Preferred Securities will cease.

         (b) In the case of an exchange described in Section 5.4(a), the Trust
will, on the date of such exchange, exchange Subordinated Deferrable Notes
having a principal amount equal to a proportional amount of the aggregate
liquidation amount of the outstanding Common Securities based on the ratio of
the aggregate liquidation amount of the Preferred Securities exchanged pursuant
to Section 5.4(a) divided by the aggregate liquidation amount of the Preferred
Securities outstanding immediately prior to such exchange, for such proportional
amount of Common Securities held by the Subordinated Deferrable Notes Issuer
(which contemporaneously shall be canceled and no longer be deemed to be
outstanding); provided, that the Subordinated Deferrable Notes Issuer delivers
or causes to be delivered to the Property Trustee or its designee the required
amount of Common Securities to be exchanged by 10:00 A.M., New York City time,
on the Distribution payment date on which such exchange is to occur.

<PAGE>   48

                  (ii) after the issuance of any Securities, by a vote of the
         Holders of a Majority in Liquidation Amount of the Common Securities at

         without prior notice in lieu of such meeting.

         (b) The Property Trustee shall not be removed in accordance with
Section 6.6(a) or Section 7.5(k) until a successor Trustee possessing the
qualifications to act as Property Trustee under Section 6.3(a) (a "Successor
Property Trustee") has been appointed and has accepted such appointment by
written instrument executed by such Successor Property Trustee and delivered to
the Regular Trustees and the Sponsor. The Delaware Trustee shall not be removed
in accordance with Section 6.6(a) or Section 7.5(k) until a successor Trustee

Any Trustee may resign from office (without need for prior or subsequent
accounting) by written instrument executed by such Trustee and delivered to the

         effective:

                           (A)  until a Successor Property Trustee has been
                                appointed and has accepted such appointment by
                                written instrument executed by such Successor
                                Property Trustee and delivered to the Regular
                                Trustees, the Sponsor and the resigning Property
                                Trustee; or

                           (B)  until the assets of the Trust have been
                                completely liquidated and the proceeds thereof
                                distributed to the Holders of the Securities;
                                and

                  (ii) no such resignation of the Delaware Trustee shall be

         accepted such appointment by written instrument executed by such
         Successor Delaware

<PAGE>   49

         Trustee and delivered to the Regular Trustees, the Sponsor and the
         resigning Delaware Trustee.

         (d) The Holders of the Common Securities shall use their best efforts
to promptly appoint a Successor Property Trustee or Successor Delaware Trustee,
as the case may be, if the Property Trustee or the Delaware Trustee delivers an
instrument of resignation in accordance with this Section 6.6.

         (e) If no Successor Property Trustee or Successor Delaware Trustee, as
the case may be, has been appointed and accepted appointment as provided in this
Section 6.6 within 60 days after delivery of an instrument of resignation or
removal, the resigning or removed Property Trustee or Delaware Trustee, as
applicable, may petition any court of competent jurisdiction for appointment of
a Successor Property Trustee or Successor Delaware Trustee, as applicable. Such
court may thereupon, after prescribing such notice, if any, as it may deem
proper, appoint a Successor Property Trustee or Successor Delaware Trustee, as
the case may be.

         (f) No Property Trustee or Delaware Trustee shall be liable for the
acts or omissions to act of any Successor Property Trustee or Successor Delaware
Trustee, as the case may be.

         (g) In case of the appointment hereunder of a Successor Property
Trustee or a Successor Delaware Trustee, such Successor Property Trustee or
Successor Delaware Trustee so appointed shall execute, acknowledge and deliver
to the Trust and to the retiring Property Trustee or Delaware Trustee, as the
case may be, an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Property Trustee or Delaware Trustee
shall become effective and such Successor Property Trustee or Successor Delaware
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Property Trustee or
Delaware Trustee; but, on the request of the Sponsor or the Successor Property
Trustee or Successor Delaware Trustee, such retiring Property Trustee or
Delaware Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such Successor Property Trustee or Successor Delaware
Trustee all the rights, powers and trusts of the retiring Property Trustee or
Delaware Trustee, as the case may be, and if the Property Trustee is the
resigning Trustee, it shall duly assign, transfer and deliver to the Successor
Property Trustee all property and money held by such retiring Property Trustee
hereunder.

         Section 6.7 Vacancies among Trustees.

                  If a Trustee ceases to hold office for any reason and the
number of Trustees is not reduced pursuant to Section 6.1, or if the number of
Trustees is increased pursuant to Section 6.1, a vacancy shall occur. A
resolution certifying the existence of such vacancy by the Regular Trustees or,
if there are more than two, a

<PAGE>   50

majority of the Regular Trustees shall be conclusive evidence of the existence
of such vacancy. The vacancy shall be filled with a Trustee appointed in
accordance with Section 6.6.

         Section 6.8 Effect of Vacancies.

                  The death, resignation, retirement, removal, bankruptcy,
dissolution, liquidation, incompetence or incapacity to perform the duties of a
Trustee shall not operate to annul, dissolve or terminate the Trust nor to
terminate this Declaration. Whenever a vacancy in the number of Regular Trustees
shall occur until such vacancy is filled by the appointment of a Regular Trustee
in accordance with Section 6.6, the Regular Trustees in office, regardless of
the number, shall have all the powers granted to the Regular Trustees and shall
discharge all the duties imposed upon the Regular Trustees by this Declaration.

         Section 6.9 Meetings.

                  If there is more than one Regular Trustee, meetings of the
Regular Trustees shall be held from time to time upon the call of any Regular
Trustee. Regular meetings of the Regular Trustees may be held at a time and
place fixed by resolution of the Regular Trustees. Notice of any in-person
meetings of the Regular Trustees shall be hand delivered or otherwise delivered
in writing (including by facsimile, with a hard copy by overnight courier) not
less than 48 hours before such meeting. Notice of any telephonic meetings of the
Regular Trustees shall be hand delivered or otherwise delivered in writing
(including by facsimile, with a hard copy by overnight courier) not less than 24
hours before a meeting. Notices shall contain a brief statement of the time,
place and anticipated purposes of the meeting. The presence (whether in person
or by telephone) of a Regular Trustee at a meeting shall constitute a waiver of
notice of such meeting except where a Regular Trustee attends a meeting for the
express purpose of objecting to the transaction of any activity on the ground
that the meeting has not been lawfully called or convened. Unless provided
otherwise in this Declaration, any action of the Regular Trustees may be taken
at a meeting by vote of a majority of the Regular Trustees present (whether in
person or by telephone) and eligible to vote with respect to such matter,
provided a Quorum is present, or without a meeting and without prior notice by
the unanimous written consent of the Regular Trustees. In the event there is
only one Regular Trustee, any and all action of such Regular Trustee shall be
evidenced by a written consent of such Regular Trustee.

         Section 6.10 Delegation of Power by the Regular Trustees.

         (a) Any Regular Trustee may delegate to any natural person over the age
of 21 that is a United States Person, by power of attorney consistent with
applicable law, his, her or its power for the purpose of executing any documents
contemplated in Section 3.6.

         (b) The Regular Trustees shall have the power to delegate from time to
time to such of their number or to officers of the Trust or any other Person the
doing of such things and the execution of such instruments either in the name of
the Trust or the names of the Regular Trustees or otherwise as the Regular
Trustees may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of the Trust, as set forth herein.

         Section 6.11 Merger, Consolidation, Conversion or Succession to
Business.

                  Any entity into which the Property Trustee, the Delaware
Trustee or any Regular Trustee that is not a natural person may be merged or
converted or with such Trustee may be consolidated, or any entity resulting from
any merger, conversion or consolidation to which such Trustee is a party, or
any entity succeeding to all or substantially all the corporate trust business
of such Trustee, shall be the successor of such Trustee hereunder, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, provided that such entity otherwise is qualified and eligible
under this Article.

                       ARTICLE 7: TERMS OF THE SECURITIES

         Section 7.1 General Provisions Regarding the Securities.

         (a) The Regular Trustees shall issue, on behalf of the Trust, one class
of preferred securities representing undivided beneficial interests in the
assets of the Trust (the "Preferred Securities") and one class of common
securities representing undivided beneficial interests in the assets of the
Trust (the "Common Securities"). The Trust shall issue no securities or other
interests in the assets of the Trust other than the Preferred Securities and the
Common Securities and the aggregate liquidation amount of all Securities issued
by the Trust and outstanding at any time shall not exceed $257,731,975.

                  (i) Preferred Securities. The Preferred Securities of the
         Trust shall have an aggregate stated liquidation amount with respect to
         the assets of the Trust of two hundred twenty million and 00/100
         dollars ($220,000,000)

<PAGE>   52

         (subject to increase to not more than two hundred fifty million and
         00/100 dollars ($250,000,000) in the event of the exercise of any
         Over-allotment Option) and a stated liquidation amount with respect to
         the assets of the Trust of $25 per Preferred Security. The Preferred
         Securities are hereby designated for identification purposes only as
         the Preferred Securities. The Preferred Security Certificates shall be
         substantially in the form of Exhibit A hereto, with such changes and
         additions thereto or deletions therefrom as may be required by
         ordinary usage, custom or practice.

                  (ii) Common Securities. The Common Securities of the Trust
         shall have an aggregate liquidation amount with respect to the assets
         of the Trust of six million eight hundred four thousand one hundred
         twenty-five and 00/100 dollars ($6,804,125) (subject to increase to not
         more than seven million seven hundred thirty-one thousand nine hundred
         seventy-five and 00/100 dollars ($7,731,975) in the event of the
         exercise of any Over-allot ment Option) and a liquidation amount with
         respect to the assets of the Trust of $25 per Common Security. The
         Common Securities are hereby designated for identification purposes
         only as the Common Securities. The Common Security Certificates shall
         be substantially in the form of Exhibit B hereto, with such changes and
         additions thereto or deletions therefrom as may be required by ordinary
         usage, custom or practice.

         (b) Except with respect to a Cash Merger Event Redemption, payment of
Distributions on, and any payment of the Redemption Price upon a redemption of,
the Preferred Securities and the Common Securities, as applicable, shall be made
Pro Rata based on the liquidation amount of such Preferred Securities and Common
Securities; provided that if on any date on which amounts payable on
distribution or redemption, an Indenture Event of Default has occurred and is
continuing, then such amounts payable shall not be made on any of the Common
Securities, and no other payment on account of the redemption, liquidation or
other acquisition of such Common Securities shall be made, until all accumulated
and unpaid Distributions, or payments of the Redemption Price, as the case may
be, on all of the outstanding Preferred Securities for which Distributions are
to be paid or that have been called for redemption, as the case may be, are
fully paid. All funds available to the Property Trustee shall first be applied
to the payment in full in cash of all Distributions on, or the Redemption Price
of, the Preferred Securities then due and payable.

         (c) The consideration received by the Trust for the issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust.

         (d) Upon issuance of the Securities as provided in this Declaration,
the Securities so issued shall be validly issued, fully paid and non-assessable
beneficial ownership interests in the assets of the Trust.

<PAGE>   53

         (e) Every Person, by virtue of having become a Holder of Securities or
a Beneficial Owner of Preferred Securities in accordance with the terms of this
Declaration, shall be deemed to have expressly assented and agreed to the terms
of, and shall be bound by, this Declaration, the Guarantee, the Indenture, the
Purchase Contract Agreement, the Pledge Agreement and the Subordinated
Deferrable Notes.

         (f) The Holders of the Securities shall not have any preemptive or
similar rights.

         (g) The Certificates shall be signed on behalf of the Trust by a
Regular Trustee. Such signature shall be the manual or facsimile signature of
any Regular Trustee. If a Regular Trustee of the Trust who has signed any of the
Certificates ceases to be a Regular Trustee before such signed Certificates have
been delivered by the Trust, such Certificates nevertheless may be delivered as
though the Person who signed such Certificates had not ceased to be a Regular
Trustee. Any Certificate may be signed on behalf of the Trust by such Persons
who, at the actual date of execution of such Certificate, shall be the Regular
Trustees of the Trust, although at the date of the execution and delivery of
this Declaration any such Person was not such a Regular Trustee. Certificates
shall be printed, lithographed or engraved or may be produced in any other
manner as is reasonably acceptable to the Regular Trustees, as evidenced by
their execution thereof, and may have such letters, numbers or other marks of
identification or designation and such legends or endorsements as the Regular
Trustees may deem appropriate, or as may be required to comply with any law or
with any rule or regulation of any stock exchange on which the Securities may be
listed, or to conform to usage.

                  A Preferred Security Certificate shall not be valid until
authenticated by the manual signature of an authorized signatory of the Property
Trustee. Such signature shall be conclusive evidence that such Preferred
Security Certificate has been authenticated under this Declaration.

                  Upon a written order of the Trust signed by one Regular
Trustee, the Property Trustee shall authenticate the Preferred Security
Certificates for original issue. The aggregate number of Preferred Securities
outstanding at any time (including the Over-allotment Option) shall not exceed
the liquidation amount set forth in Section 7.1(a)(i).

                  The Property Trustee may appoint an authenticating agent
acceptable to the Trust, as determined by the Regular Trustees on behalf of the
Trust, to

<PAGE>   54

authenticate Certificates. An authenticating agent may authenticate Certificates
whenever the Property Trustee may do so. Each reference in this Declaration to
authentication by the Property Trustee shall include authentication by such
agent. An authenticating agent shall have the same rights as the Property
Trustee to deal with the Sponsor or an Affiliate of the Sponsor.

         (h) The Preferred Securities Certificates, upon original issuance
(including Preferred Securities, if any, issued pursuant to the exercise of any
Over-allotment Option), shall be issued as Global Securities in the form of one
or more fully registered global Preferred Security Certificates (each a "Global
Certificate"), to be delivered to The Depository Trust Company, the initial
Depositary, by or on behalf of the Trust. Such Global Certificates initially
shall be registered on the books and records of the Trust in the name of "Cede &
Co.," the nominee of the initial Depositary. No Beneficial Owner of Preferred
Securities shall receive a definitive Preferred Security Certificate
representing such Beneficial Owner's interests in such Global Certificates,
except as provided in Section 7.12. Unless and until definitive, fully
registered Preferred Security Certificates have been issued to the Beneficial
Owners of Preferred Securities pursuant to Section 7.12,

                  (i) the provisions of this Section 7.1 shall be in full force
         and effect;

                  (ii) the Trust and the Trustees shall be entitled to deal with
         the Depositary for all purposes of this Declaration (including the
         payment of Distributions on the Global Certificates and receiving
         approvals, votes or consents thereunder) as the Holder of the Preferred
         Securities and the sole Holder of the Global Certificates and, except
         as set forth herein or in Rule 3a- 7 (if the Trust is excluded from the
         definition of an Investment Company solely by reason of Rule 3a-7) with
         respect to the Property Trustee, shall have no obligation to the
         Beneficial Owners of the Preferred Securities;

                  (iii) to the extent that the provisions of this Section 7.1
         conflict with any other provisions of this Declaration, the provisions
         of this Section 7.1 shall control; and

                  (iv) the rights of the Beneficial Owners of the Preferred
         Securities shall be exercised only through the Depositary and shall be
         limited to those established by law and agreements between such
         Beneficial Owners and the Depositary and/or the Depositary
         Participants. The Depositary shall make book-entry transfers among
         Depositary Participants and receive and transmit Distributions on the
         Global Certificates to such Depositary Participants; provided that
         solely for the purposes of determining whether the Holders of
         the requisite amount of Preferred Securities have voted on any matter
         provided for in this Declaration, so long as definitive Preferred
         Security

<PAGE>   55

         Certificates have not been issued, the Trustees may rely conclusively
         on, and shall be fully protected in relying on, any written instrument
         (including a proxy) delivered to the Trustees by the Depositary
         setting forth the votes of the Beneficial Owners of the Preferred
         Securities or assigning the right to vote on any matter to any other
         Persons either in whole or in part.

                  Whenever a notice or other communication to the Holder of the
Preferred Securities is required to be given under this Declaration, unless and
until definitive Preferred Security Certificates have been issued pursuant to
Section 7.1(g), the Trustees shall deliver all such notices and communications
specified herein to be given to the Holders of the Preferred Securities to the
Depositary, and, with respect to any Preferred Security Certificate registered
in the name of a Depositary or the nominee of a Depositary, the Trustees may
conclusively rely on, and shall be fully protected in relying on, any written
instrument (including a proxy) delivered to the Trustees by the Depositary
setting forth the votes of the Beneficial Owners of the Preferred Securities or
assigning the right to vote on any matter or any other Persons either in whole
or in part.

         Section 7.2 Distributions.

         (a) Holders of the Securities shall be entitled to receive
Distributions that shall accumulate and be payable at the rate per annum of   %
of the stated liquidation amount of $25 per Security until August 18, 2003, and
at the Reset Rate thereafter. The amount of Distributions payable for any period
shall be computed (i) for any full quarterly distribution period, on the basis
of a 360-day year of twelve 30-day months and (ii) for any period shorter than a
full quarterly distribution period, on the basis of a 30-day month and, for any
period of less than one month, on the basis of the actual number of days elapsed
per 30-day month. Subject to Section 7.1(b), Distributions shall be made on the
Securities on a Pro Rata basis. Distributions on the Securities shall accumulate
from August 22, 2000, shall be cumulative and shall be payable quarterly, in
arrears, on August 18, November 18, February 18 and May 18 of each year,
commencing November 18, 2000, when, as and if available for payment, by the
Property Trustee, except as otherwise described below. Distributions shall be
payable only to the extent that payments are made to the Trust in respect of the
Subordinated Deferrable Notes held by the Property Trustee and to the extent
that the Trust has funds available for the payment of such Distributions in the
Property Account.

         (b) Distributions not paid on the scheduled payment date shall
accumulate and compound quarterly at the rate of   % per annum through and
including August 18, 2003 and at the Reset Rate thereafter ("Compounded
Distributions").

<PAGE>   56

"Distributions" shall mean ordinary cumulative distributions together with any
Compounded Distributions.

         (c) Except with respect to a Cash Merger Event Redemption, if and to
the extent that the Subordinated Deferrable Notes Issuer makes a payment of
principal of and any premium or interest on the Subordinated Deferrable Notes
held by the Property Trustee (the amount of any such payment being a "Payment
Amount"), the Property Trustee shall and is directed, to the extent funds are
available for that purpose, to make a Pro Rata distribution of the Payment
Amount to Holders, subject to Section 7.1(b). Redemption payments made on the
Subordinated Deferrable Notes held by the Property Trustee in connection with a
Cash Merger Event Redemption shall only be distributed as set forth in Section
7.3 (c) hereof.

         (d) Distributions on the Securities shall be payable to the Holders
thereof as they appear on the register of the Trust as of the close of business
on the relevant record dates. If the Preferred Securities are represented by one
or more Global Securities, the relevant record dates shall be the close of
business on the Business Day preceding such Distribution payment date, unless a
different regular record date is established or provided for the corresponding
interest payment date on the Subordinated Deferrable Notes. The relevant record
dates for the Common Securities shall be the same as for the Preferred
Securities. If the Preferred Securities are not represented by one or more
Global Securities, the relevant record dates for the Preferred Securities shall
be selected by the Regular Trustees and shall be the fifteenth Business Day
prior to the relevant Distribution payment dates. At all times, the Distribution
payment dates shall correspond to the interest payment dates on the Subordinated
Deferrable Notes. Distributions payable on any Securities that are not
punctually paid on any Distribution payment date, as a result of the
Subordinated Deferrable Notes Issuer having failed to make a payment under the
Subordinated Deferrable Notes, shall cease to be payable to the Person in whose
name such Securities are registered on the relevant record date, and such
defaulted Distribution instead shall be payable to the Person in whose name such
Securities are registered on the special record date or other specified date
determined in accordance with this Declaration. If any date on which
Distributions are payable on the Securities is not a Business Day, then payment
of the Distribution payable on such date shall be made on the next day that is a
Business Day (and without any interest or other payment in respect of any such
delay), except that if such Business Day is in the next calendar year, such
payment shall be made on the preceding Business Day, with the same force and
effect as if made on such payment date.

         (e) In the event that there is any money or other property held by or
for

<PAGE>   57

the Trust that is not accounted for hereunder, such property shall be
distributed Pro Rata among the Holders of the Securities, subject to Section
7.1(b).

         Section 7.3       Redemption of Securities.

         (a) With respect to redemptions other than in connection with a Cash
Merger Event Redemption, upon the repayment or redemption, in whole or in part,
of the Subordinated Deferrable Notes held by the Trust, whether at the stated
maturity of the Subordinated Deferrable Notes or upon earlier redemption as
provided in the Indenture, the proceeds from such repayment or redemption shall
be simultaneously applied Pro Rata (subject to Section 7.1(b)) to redeem
Securities having an aggregate liquidation amount equal to the aggregate
principal amount of the Subordinated Deferrable Notes so repaid or redeemed at
the Redemption Price. Holders of the Securities shall be given not less than 30
nor more than 60 days notice of such redemption in accordance with Section 7.4.

         (b) If the Subordinated Deferrable Notes Issuer redeems the
Subordinated Deferrable Notes upon the occurrence and continuance of a Tax
Event, the proceeds from such redemption shall be applied by the Property
Trustee to redeem the Securities in whole (but not in part) at a redemption
price per Security equal to the Redemption Amount plus any accumulated and
unpaid Distributions thereon to the Tax Event Redemption Date. If, following the
occurrence of a Tax Event, the Subordinated Deferrable Notes Issuer exercises
its option to redeem the Subordinated Deferrable Notes, the Subordinated
Deferrable Notes Issuer shall appoint the Quotation Agent; if a Tax Event
Redemption occurs prior to the Purchase Contract Settlement Date, the redemption
price payable in liquidation of the Securities that are part of PEPS Units will
be distributed to The Chase Manhattan Bank, acting as the securities
intermediary under the Pledge Agreement, which in turn will apply that amount to
purchase the Treasury Portfolio and remit the remaining portion, if any, of such
price to The Bank of New York, acting as the purchase contract agent under the
Purchase Contract Agreement, for payment to the Holders of the Securities. If a
Tax Event Redemption occurs after the Purchase Contract Settlement Date, the
Treasury Portfolio shall not be purchased and the Property Trustee shall
distribute to the
Holders of the Securities on the Tax Event Redemption Date the Redemption Price
payable in liquidation of such Holders' interests in the assets of the Trust.

         (c) In connection with a Cash Merger Event, each Holder of Securities
shall have the right to require the Trust to redeem all or any part (equal to
$25 or an integral multiple thereof) of such Holder's Securities pursuant to the
offer described below (the "Cash Merger Event Offer") at an offer price in cash
equal to the applicable Redemption Price.

                  No later than the day of the Cash Merger Event, the Trust
shall mail or cause to be mailed a notice of a pending Cash Merger Event to each
Holder (at its last

<PAGE>   58

registered address with a copy to the Trustee and the Paying Agent) offering to
repurchase the Securities held by such Holder pursuant to the procedures
specified in such notice. The Cash Merger Event Offer shall remain open from the
time of mailing until at least 5:00 p.m. on the last day of the second week
immediately following the last day of the corresponding Early Settlement Week.
The notice, which shall govern the terms of the Cash Merger Event Offer, shall
contain all instructions and materials necessary to enable the Holders to tender
Securities pursuant to the Cash Merger Event Offer and shall state:

                  (i) that the Cash Merger Event Offer is being made pursuant to
         this Section 7.3(c) and that all Securities tendered will be accepted
         for payment;

                  (ii) the applicable Redemption Price and the Cash Merger
         Redemption Date (as such term is defined below in this Section 7.3(c)),
         which date shall be no earlier than 20 business days from the date such
         notice is mailed;

                  (iii) that any Security not tendered will continue to accrue
         Distributions in accordance with this Declaration;

                  (iv) that, unless the Trust defaults in the payment of the
         applicable Redemption Price, all Securities accepted for payment
         pursuant to the Cash Event Merger Offer will cease to accrue interest
         after the Cash Merger Redemption Date;

                  (v) that Holders electing to have a Security purchased
         pursuant to any Cash Event Merger Offer will be required to surrender
         the Security, with the form entitled "Option of Holder to Elect
         Purchase" on the reverse of the Security completed, to the Trust, a
         depositary, if appointed by the Trust, or a Paying Agent at the address
         specified in the notice prior to the 5:00 p.m. on the last day of the
         second week immediately following the end of the corresponding Early
         Settlement Week;

                  (vi) that Holders will be entitled to withdraw their election
         if the Trust, depositary or Paying Agent, as the case may be, receives,
         not later than 5:00 p.m. on the last day of the second week immediately
         following the end of the corresponding Early Settlement Week, a
         facsimile transmission or letter setting forth the name of the Holder,
         the liquidation amount of the Securities the Holder delivered for
         purchase, and a statement that such Holder is

<PAGE>   59

         withdrawing his election to have such Securities purchased;

                  (vii) that Holders whose Securities are being purchased only
         in part will be issued new Securities equal in liquidation amount to
         the unpurchased portion of the Securities surrendered, which
         unpurchased portion must be equal to $25 in liquidation amount or an
         integral multiple thereof; and

                  (viii) the circumstances and relevant facts regarding such
         Cash Merger Event and any other information that would be material to a
         decision as to whether to tender a Security pursuant to the Cash Merger
         Event Offer.

                  On the Cash Merger Redemption Date, the Trust shall, to the
extent lawful, (x) accept for payment all Securities or portions thereof
properly tendered and not withdrawn pursuant to the Cash Merger Event Offer, (y)
deposit with the Paying Agent an amount equal to the Cash Merger Event Payment
in respect of all Securities or portions thereof so tendered and (z) deliver or
cause to be delivered to the Trustee the Securities so accepted together with an
Officers' Certificate stating the aggregate liquidation amount of Securities or
portions thereof being purchased by the Trust. The Paying Agent shall promptly
mail to each Holder of Securities so tendered the Redemption Price for each such
Security, and the Property Trustee shall promptly authenticate and mail (or
cause to be transferred by book entry) to each Holder a new Security equal in
liquidation amount to any unpurchased portion of the Securities surrendered, if
any; provided that each such new Security shall be in a liquidation amount of
$25 or an integral multiple thereof. The Trust shall publicly announce the
results of the Cash Merger Event Offer on or as soon as practicable after the
applicable Cash Merger Redemption Date.

                  The Trust shall comply with the requirements of Rule 14e-1 and
Rule 13e-4 under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection
with the redemption of Securities as a result of a Cash Merger Event.

                  The aggregate Redemption Price to be paid in connection with
this Section 2.5(b) shall be paid prior to 12:00 noon, New York City time, on
the Business Day immediately following the last day of the second week
immediately following the last day of the corresponding Early Settlement Week
(the "Cash Merger Redemption Date") or such earlier time as the Trust
determines, provided that the Trust shall have deposited with the Trustee an
amount sufficient to pay the aggregate Redemption Price by 10:00 a.m. on the
Cash Merger Redemption Date.

         Section 7.4       Redemption Procedures.

         (a) Except with respect to any Cash Merger Event Redemption, notice of
any redemption of, or notice of distribution of Subordinated Deferrable Notes in

<PAGE>   60

exchange for, the Securities (a "Redemption/Distribution Notice"), which notice
shall be irrevocable, shall be given by the Trust by mail to each Holder of
Securities to be redeemed or exchanged at least 30 but no more than 60 days
before the date fixed for redemption or exchange thereof which, in the case of a
redemption, shall be the date fixed for redemption of the Subordinated
Deferrable Notes. For purposes of the calculation of the date of redemption or
exchange and the dates on which notices are given pursuant to this Section
7.4(a), a Redemption/Distribution Notice shall be deemed to be given on the day
such notice is first mailed by first-class mail, postage prepaid, to the Holders
of the Securities. Each Redemption/Distribution Notice shall be addressed to the
Holders of the Securities at the address of each such Holder appearing in the
register of the Trust. All notices of redemption shall state:

                  (i) the date fixed for redemption;

                  (ii) the Redemption Price;

                  (iii) the applicable CUSIP number;

                  (iv) if less than all of the outstanding Securities are to be
         re deemed, the identification and amount of the particular Trust
         securities to be redeemed;

                  (v) that on the date fixed for redemption the Redemption Price
         will become due and payable upon each Security to be redeemed and that
         Distributions thereon will cease to accrue on and after said date; and

                  (vi) the place or places where such Securities are to be
         surrendered for payment of the Redemption Price.

No defect in the Redemption/Distribution Notice or in the mailing of either
thereof with respect to any Holder shall affect the validity of the redemption
or exchange proceedings with respect to any other Holder.

         (b) With respect to redemptions other than a Cash Merger Event
Redemption, subject to the Trust's fulfillment of the notice requirements set
forth in Section 7.4(a), if Securities are to be redeemed, then (provided that
the Subordinated Deferrable Notes Issuer has paid the Property Trustee a
sufficient amount of cash in connection with the related redemption or maturity
of the Subordinated Deferrable Notes) (i) with respect to the Preferred
Securities represented by one or more Global Securities, by 12:00 noon, New York
City time, on the redemption date, the Property Trustee will deposit irrevocably
with the Depositary or its nominee funds sufficient to

<PAGE>   61

pay the applicable Redemption Price, and the Property Trustee shall give the
Depositary irrevocable instructions and authority to pay the Redemption Price to
the Beneficial Owners of the Preferred Securities, and (ii) with respect to
Securities not represented by one or more Global Securities, the Property
Trustee shall pay the applicable Redemption Price to the Holders of such
Securities by check mailed to the address of each Holder appearing on the
register of the Trust on the redemption date. If any date fixed for redemption
of Securities is not a Business Day, then payment of the Redemption Price
payable on such date shall be made on the next Business Day (without any
interest thereon), except that if such Business Day falls in the next calendar
year, such payment shall be made on the preceding Business Day, in each case
with the same force and effect as if made on such date fixed for redemption.
Notwithstanding the foregoing, so long as the Holder of any Preferred Securities
is the Collateral Agent or the Purchase Contract Agent, the payment of the
Redemption Price in respect of the Preferred Securities held by the Collateral
Agent or the Purchase Contract Agent shall be made no later than 12:00 noon, New
York City time, on the redemption date by check or wire transfer in immediately
available funds at such place and to such account as may be designated by the
Collateral Agent or the Purchase Contract Agent. If payment of the Redemption
Price in respect of any Securities is improperly withheld or refused and not
paid either by the Trust or by the Sponsor as guarantor pursuant to the
Guarantee, then Distributions on such Securities shall continue to accumulate at
the then applicable rate, from the original redemption date to the actual date
of payment, in which case the actual payment date shall be the date fixed for
redemption for purposes of calculating the Redemption Price. For these purposes,
the applicable Redemption Price shall not include Distributions that are being
paid to Holders of Securities who were not Holders of Securities on a relevant
record date. If a Redemption/Distribution Notice has been given and funds have
been deposited or paid as required, then immediately prior to the close of
business on the date of such deposit or payment, Distributions will cease to
accumulate on the Securities called for redemption, and all rights of Holders of
such Securities so called for redemption shall cease, except the right of the
Holders of such Securities to receive the Redemption Price, but without interest
on such Redemption Price, and from and after the date fixed for redemption, such
Securities will cease to be outstanding.

                  Neither the Regular Trustees nor the Trust shall be required
to register or cause to be registered the transfer of any Securities that have
been called for redemption, except for the unredeemed portion of any Securities
being redeemed in part.

         (c) Subject to the foregoing and applicable law (including, without

<PAGE>   62

limitation, United States federal securities laws), the Subordinated Deferrable
Notes Issuer or its Affiliates may purchase, at any time and from time to time,
outstanding Preferred Securities by tender, in the open market, by private
agreement or other wise.

         Section 7.5       Voting Rights of the Preferred Securities.

         (a) Except as provided under this Section 7.5 and Section 11.1 and as
otherwise required by the Business Trust Act, the Trust Indenture Act and other
applicable law, the Holders of the Preferred Securities shall have no voting
rights.

         (b) Subject to the requirement of the Property Trustee obtaining a tax
opinion in certain circumstances set forth in Section 7.5(d), the Holders of a
Majority in Liquidation Amount of the Preferred Securities, voting separately as
a class, shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Property Trustee, or to direct
the exercise of any trust or power conferred upon the Property Trustee under
this Declaration, including the right to direct the Property Trustee, as Holder
of the Subordinated Deferrable Notes, to (i) exercise the remedies available to
it under the Indenture, (ii) consent to any amendment or modification of the
Indenture or the Subordinated Deferrable Notes where such consent is required or
(iii) waive any past default and its consequences that are waivable under the
Indenture; provided that if an Indenture Event of Default has occurred and is
continuing, then the Holders of 25% of the aggregate stated liquidation amount
of the Preferred Securities may direct the Property Trustee to declare the
principal of and interest on the Subordinated Deferrable Notes due and payable;
provided further that where a consent or action under the Indenture would
require the consent or act of the Holders of more than a majority of the
aggregate principal amount of Subordinated Deferrable Notes affected thereby,
the Property Trustee only may give such consent or take such action at the
direction of the Holders of at least the same proportion in aggregate stated
liquidation amount of the Preferred Securities; and provided further, however,
that (subject to the provisions of Section 3.09) the Property Trustee shall have
the right to decline to follow any such direction if the Property Trustee, being
advised by counsel, determines that the action or proceeding so directed may not
lawfully be taken or if the Property Trustee, in good faith, by its board of
directors or trustees, executive committee, or a trust committee of directors or
trustees, and/or Responsible Officers, shall determine that the action or
proceeding so directed would involve the Property Trustee in personal liability.

         (c) If the Property Trustee fails to enforce its rights under the
Subordinated Deferrable Notes after a Holder of Preferred Securities has made a
written request, such Holder of Preferred Securities may institute, to the
fullest extent permitted by law, a legal proceeding directly against the
Subordinated Deferrable Notes Issuer to enforce the Property Trustee's rights
under the Indenture without first instituting any legal proceeding against the
Property Trustee or any other Person. In addition, if a Trust Enforcement Event
has occurred and is continuing and such event

<PAGE>   63

is attributable to the failure of the Subordinated Deferrable Notes Issuer to
make any interest, principal or other required payments when due under the
Indenture, then a Holder of Preferred Securities may institute a Direct Action
against the Subordinated Deferrable Notes Issuer on or after the respective due
date specified in the Subordinated Deferrable Notes. In connection with such
Direct Action, the Subordinated Deferrable Notes Issuer will be subrogated to
the rights of such Holder of Preferred Securities to the extent of any payment
made by the Subordinated Deferrable Notes Issuer to such Holders of Preferred
Securities in such Direct Action.

         (d) The Property Trustee shall notify all Holders of the Preferred
Securities of any notice of any Indenture Event of Default received from the
Subordinated Deferrable Notes Issuer with respect to the Subordinated Deferrable
Notes. Such notice shall state that such Indenture Event of Default also
constitutes a Trust Enforcement Event. Except with respect to directing the
time, method, and place of conducting a proceeding for a remedy, the Property
Trustee shall be under no obligation to take any of the actions described in
clauses (i) and (ii) of Section 7.5(b) above, unless the Property Trustee has
obtained an opinion of independent tax counsel to the effect that the Trust will
not fail to be classified as a grantor trust for United States federal income
tax purposes as a result of such action, and that each Holder of Preferred
Securities shall be treated as owning an undivided beneficial ownership interest
in the Subordinated Deferrable Notes.

         (e) If the consent of the Property Trustee, as the Holder of the
Subordinated Deferrable Notes, is required under the Indenture with respect to
any amendment or modification of the Indenture, the Property Trustee shall
request the direction of the Holders of the Securities with respect to such
amendment or modification and shall vote with respect to such amendment or
modification as directed by a Majority in Liquidation Amount of the Securities
voting together as a single class; provided that where a consent under the
Indenture would require the consent of the Holders of more than a majority of
the aggregate principal amount of the Subordinated Deferrable Notes, the
Property Trustee only may give such consent at the direction of the Holders of
at least the same proportion in aggregate stated liquidation amount of the
Securities. The Property Trustee shall not take any such action in accordance
with the directions of the Holders of the Securities unless the Property Trustee
has obtained an opinion of independent tax counsel to the effect that the Trust
will not be classified as other than a grantor trust for United States federal
income tax purposes as a result of such action, and that each Holder will be
treated as owning an undivided beneficial ownership interest in the Subordinated
Deferrable Notes.

<PAGE>   64

         (f) A waiver of an Indenture Event of Default with respect to the
Subordinated Deferrable Notes shall constitute a waiver of the corresponding
Trust Enforcement Event.

         (g) Any required approval or direction of the Holders of the Preferred
Securities may be given at a separate meeting of the Holders of the Preferred
Securities convened for such purpose, at a meeting of all of the Holders of the
Securities or pursuant to written consent without prior notice. The Regular
Trustees shall cause a notice of any meeting at which Holders of the Preferred
Securities are entitled to vote to be mailed to each Holder of record of
Preferred Securities. Each such notice shall include a statement setting forth:
(i) the date of such meeting; (ii) a description of any resolution proposed for
adoption at such meeting on which such Holders are entitled to vote; and (iii)
instructions for the delivery of proxies.

         (h) No vote or consent of the Holders of the Preferred Securities shall
be required for the Trust to redeem and cancel the Preferred Securities or
distribute the Subordinated Deferrable Notes in accordance with this Declaration
and the terms of the Securities.

         (i) Notwithstanding that the Holders of the Preferred Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Preferred Securities that are owned at such time by the Subordinated
Deferrable Notes Issuer the Trustees or any entity directly or indirectly
controlled by, or under direct or indirect common control with, the Subordinated
Deferrable Notes Issuer or any Trustee shall not be entitled to vote or consent
and shall be treated, for purposes of such vote or consent, as if such Preferred
Securities were not outstanding.

         (j) Except as provided under Section 7.5(k), the Holders of the
Preferred Securities shall have no rights to appoint or remove the Trustees,
who, subject to Section 6.6, may be appointed, removed or replaced by the
Holders of the Common Securities.

         (k) If an Indenture Event of Default has occurred and is continuing,
the Property Trustee and the Delaware Trustee may be removed and replaced,
subject to Section 6.6(b), at such time by a Majority in Liquidation Amount of
the Preferred Securities.

         Section 7.6       Voting Rights of the Common Securities.

         (a) Except as provided under Section 6.1(b), this Section 7.6 and
         Section

<PAGE>   65
 11.1 and as otherwise required by the Business Trust Act, the Trust Indenture
Act or other applicable law or provided by this Declaration, the Holders of the
Common Securities shall have no voting rights.

         (b) Subject to Section 7.5(k), the Holders of the Common Securities
shall be entitled to vote to appoint, remove or replace any Trustee or to
increase or decrease the number of Trustees in accordance with Article 6.

         (c) Subject to Section 2.6 and only after all Trust Enforcement Events
with respect to the Preferred Securities have been cured, waived, or otherwise
eliminated and subject to the requirement of the Property Trustee obtaining a
tax opinion in certain circumstances set forth in this paragraph (c), the
Holders of the Common Securities shall have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Property
Trustee, or to direct the exercise of any trust or power conferred upon the
Property Trustee under this Declaration, including the right to direct the
Property Trustee, as Holder of the Subordinated Deferrable Notes, to (i)
exercise the remedies available to it under the Indenture, (ii) consent to any
amendment or modification of the Indenture or the Subordinated Deferrable Notes
where such consent is required or (iii) waive any past default and its
consequences that are waivable under the Indenture; provided that where a
consent or action under the Indenture would require the consent or act of the
Holders of more than a majority of the aggregate principal amount of
Subordinated Deferrable Notes affected thereby, only the Holders of at least the
same proportion of the aggregate stated liquidation amount of the Common
Securities may direct the Property Trustee to give such consent or take such
action. Except with respect to directing the time, method, and place of
conducting a proceeding for a remedy, the Property Trustee shall be under no
obligation to take any of the actions described in clause 7.6(c)(i) and (ii)
above unless the Property Trustee has obtained an opinion of independent tax
counsel to the effect that, as a result of such action, for United States
federal income tax purposes the Trust will not fail to be classified as a
grantor trust and each Holder will be treated as owning an undivided beneficial
ownership interest in the Subordinated Deferrable Notes.

         (d) If the Property Trustee fails to enforce its rights under the
Subordinated Deferrable Notes after the Holders of the Common Securities have
made a written request, the Holders of the Common Securities may institute, to
the fullest extent permitted by law, a legal proceeding directly against the
Subordinated Deferrable Notes Issuer to enforce the Property Trustee's rights
under the Subordinated Deferrable Notes without first instituting any legal
proceeding against the Property Trustee or any other Person.

         (e) A waiver of an Indenture Event of Default with respect to the
Subordinated Deferrable Notes shall constitute a waiver of the corresponding
Trust Enforcement Event.

<PAGE>   66

         (f) Any required approval or direction of the Holders of the Common
Securities may be given at a separate meeting of the Holders of the Common
Securities convened for such purpose, at a meeting of all of the Holders of the
Securities or pursuant to written consent without prior notice. The Regular
Trustees shall cause a notice of any meeting at which the Holders of the Common
Securities are entitled to vote to be mailed to the Holders of the Common
Securities. Such notice shall include a statement setting forth: (i) the date of
such meeting; (ii) a description of any resolution proposed for adoption at such
meeting on which the Holders of the Common Securities are entitled to vote; and
(iii) instructions for the delivery of proxies.

         (g) No vote or consent of the Holders of the Common Securities shall be
required for the Trust to redeem and cancel the Common Securities or to
distribute Subordinated Deferrable Notes in accordance with this Declaration and
the terms of the Securities.

         Section 7.7       Paying Agent.

                  If any Preferred Securities are not represented by one or more
Global Securities, the Trust shall maintain in the Borough of Manhattan, New
York City, State of New York, an office or agency where the Preferred Securities
may be presented for payment ("Paying Agent"). The Regular Trustees shall
appoint the paying agent (which shall be a bank or trust company acceptable to
the Subordinated Deferrable Notes Issuer) and may appoint one or more additional
paying agents in such other locations as they shall determine. The term "Paying
Agent" includes any additional paying agent. The Regular Trustees may change any
Paying Agent without prior notice to the Holders of the Securities. The Regular
Trustees shall notify the Property Trustee of the name and address of any Paying
Agent not a party to this Declaration. If the Regular Trustees, on behalf of the
Trust, fail to appoint or maintain another entity as Paying Agent, the Property
Trustee shall act as such. The Paying Agent shall be permitted to resign as
Paying Agent upon 30 days' written notice to the Property Trustee and the
Subordinated Deferrable Notes Issuer.

         Section 7.8       Listing.

                  The Sponsor shall use its best efforts to cause the PEPS Units
to be listed and maintained as listed for quotation on the New York Stock
Exchange.

<PAGE>   67

         Section 7.9       Transfer of the Securities.

              (a) (i) The Preferred Securities initially shall be pledged,
         pursuant to the terms of the Pledge Agreement, as collateral to secure
         the obligations of the Holders of PEPS Units to purchase common shares
         of the Company in accordance with the terms of the Purchase Contract
         Agreement.

                  (ii) The Preferred Securities may be transferred, in whole or
         in part, only in accordance with the terms and conditions set forth in
         this Declaration and pursuant to the Pledge Agreement. To the fullest
         extent permitted by law, any transfer or purported transfer of any
         Preferred Security not made in accordance with this Declaration shall
         be null and void.

                  (iii) Subject to this Section 7.9 and Section 7.12, the
         Preferred Securities shall be freely transferable.

                  (iv) The Trust shall cause to be kept at the Corporate Trust
         Office a register in which, subject to such reasonable regulations as
         it may prescribe, the Trust shall provide for the registration of
         Preferred Securities and of transfers of Preferred Securities. The
         Property Trustee is hereby appointed "Security Registrar" for the
         purpose of registering Preferred Securities and transfers of Preferred
         Securities as herein provided.

                  (v) Upon surrender for registration of transfer of any
         Preferred Securities at an office or agency of the Trust designated for
         such purpose, a Regular Trustee shall execute, and the Property Trustee
         shall authenticate and deliver, in the name of the designated
         transferee or transferees, one or more new Preferred Securities of any
         authorized denominations and of a like aggregate principal amount.

                  (vi) At the option of the Holder, Securities may be exchanged
         for other Preferred Securities of any authorized denominations and of a
         like aggregate principal amount, upon surrender of the Preferred
         Securities to be exchanged at such office or agency. Whenever any
         Preferred Securities are so surrendered for exchange, a Regular Trustee
         shall execute, and the Property Trustee shall authenticate and
         deliver, the Preferred Securities that the Holder making the exchange
         is entitled to receive.

                  (vii) If so required by the Trust or the Property Trustee,
         every Preferred Security presented or surrendered for registration of
         transfer or for exchange shall be duly endorsed, or accompanied by a
         duly executed written

<PAGE>   68

         instrument of transfer in form satisfactory to the Trust and the
         Security Registrar, by the Holder thereof or his attorney duly
         authorized in writing.

                  (viii) No service charge shall be made for any registration of
         transfer or exchange of Preferred Securities, but the Trust may require
         payment of a sum sufficient to cover any tax or other governmental
         charge that may be imposed in connection with any registration of
         transfer or exchange of Preferred Securities.

         (b) The Subordinated Deferrable Notes Issuer may not transfer the
Common Securities except in connection with the transactions permitted under
Section 801 of the Indenture; provided, that each Holder of the Common
Securities shall at all times be a United States Person. To the fullest extent
permitted by law, any attempted transfer of the Common Securities other than as
set forth in this Section 7.9(b) shall be null and void.

         Section 7.10      Mutilated, Destroyed, Lost or Stolen Certificates.

                  If:

         (a) any mutilated Certificates are surrendered to the Regular Trustees,
or if the Regular Trustees receive evidence to their satisfaction of the
destruction, loss or theft of any Certificate; and

         (b) there shall be delivered to the Regular Trustees such security or
indemnity as may be required by them to keep each of them and the Property
Trustee harmless, then, in the absence of notice that such Certificate has been
acquired by a bona fide purchaser, any Regular Trustee shall execute and the
Property Trustee shall authenticate and deliver, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of
like denomination. In connection with the issuance of any new Certificate under
this Section 7.10, the Regular Trustees may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection therewith. Any duplicate Certificate issued pursuant to this Section
7.10 shall constitute conclusive evidence of an ownership interest in the
relevant Securities, as if originally issued, whether or not the lost, stolen or
destroyed Certificate is found at any time.

         Section 7.11      Deemed Holders.

                  The Trustees may treat the Person in whose name any
Certificate is registered on the register of the Trust as the sole holder of
such Certificate and of the Securities represented thereby for purposes of
receiving Distributions and for all other purposes whatsoever. Accordingly, the
Trustees shall not be bound to recognize any equitable or other claim to or
interest in such Certificate or in the Securities

<PAGE>   69

represented by such Certificate on the part of any Person, whether or not the
Trust has actual or other notice thereof.

         Section 7.12      Global Securities.

                  The Preferred Securities initially shall be issued in the form
of one or more Global Securities. A Regular Trustee on behalf of the Trust shall
execute, and the Property Trustee shall authenticate and deliver, one or more
Global Securities that (i) shall represent and be denominated in an amount equal
to the aggregate stated liquidation amount of all of the Preferred Securities to
be issued in the form of Global Securities and not yet canceled, (ii) shall be
registered in the name of the Depositary for the Preferred Securities or the
nominee of such Depositary and (iii) shall be delivered by the Property Trustee
to such Depositary or pursuant to such Depositary's instructions. Global
Securities shall bear a legend substantially to the following effect:

                  "This Preferred Security is a Global Security within the
                  meaning of the Declaration and is registered in the name of
                  The Depository Trust Company, a New York corporation (the
                  "Depositary"), or a nominee of the Depositary. This Preferred
                  Security is exchangeable for Preferred Securities registered
                  in the name of a person other than the Depositary or its
                  nominee only in the limited circumstances described in the
                  Declaration, and no transfer of this Preferred Security (other
                  than a transfer of this Preferred Security as a whole by the
                  Depositary to a nominee of the Depositary or by a nominee of
                  the Depositary to the Depositary or another nominee of the
                  Depositary) may be reregistered except in limited
                  circumstances.

                  Unless this certificate is presented by an authorized
                  representative of the Depositary to CMS Energy Trust III or
                  its agent for registration of transfer, exchange or payment,
                  and any certificate issued is registered in the name of Cede &
                  Co. or such other name as requested by an authorized
                  representative of the Depositary (and any payment hereon is
                  made to Cede & Co. or to such other entity as is requested by
                  an authorized representative of the Depositary), and except as
                  otherwise provided in the Amended and Restated Declaration of
                  CMS Energy Trust III dated as of August 22, 2000, as amended
                  from time to time, ANY TRANSFER, PLEDGE OR OTHER USE HEREOF
                  FOR VALUE OR OTHERWISE BY OR TO ANY PERSON (OTHER THAN
                  PURSUANT TO THE PLEDGE AGREEMENT) IS WRONGFUL since the
                  registered owner hereof, Cede & Co., has an interest herein."

<PAGE>   70

                  Preferred Securities not represented by a Global Security
issued in exchange for all or a part of a Global Security pursuant to this
Section 7.12 shall be registered in such names and in such authorized
denominations as the Depositary, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Property Trustee. Upon
execution and authentication, the Property Trustee shall deliver any Preferred
Securities not represented by a Global Security to the Persons in whose names
such definitive Preferred Securities are so registered.

                  At such time as all interests in Global Securities have been
redeemed, repurchased or canceled, such Global Securities shall be canceled,
upon receipt thereof, by the Property Trustee in accordance with standing
procedures of the Depositary. At any time prior to such cancellation, if any
interest in a Global Security is exchanged for Preferred Securities not
represented by a Global Security, redeemed, canceled or transferred to a
transferee who receives Preferred Securities not represented by a Global
Security, or if any Preferred Security not represented by a Global Security is
exchanged or transferred for part of a Global Security, then, in accordance with
the standing procedures of the Depositary, the liquidation amount of such Global
Security shall be reduced or increased, as the case may be, and an endorsement
shall be made on such Global Security by the Property Trustee to reflect such
reduction or increase.

                  The Trust and the Property Trustee, as the authorized
representative of the Holders of the Preferred Securities, may deal with the
Depositary for all purposes of this Declaration, including the making of
payments due on the Preferred Securities and exercising the rights of Holders of
the Preferred Securities hereunder. The rights of any Beneficial Owner shall be
limited to those established by law and agreements between such owners and
Depository Participants; provided that no such agreement shall give to any
Person any rights against the Trust or the Property Trustee without the written
consent of the parties so affected. Multiple requests and directions from and
votes of the Depositary as the Holder of the Preferred Securities represented by
Global Securities with respect to any particular matter shall not be deemed
inconsistent to the extent they do not represent an amount of Preferred
Securities in excess of those held in the name of the Depositary or its nominee.

                  If at any time the Depositary notifies the Trust that it is
unwilling or unable to continue as Depositary for the Preferred Securities or if
at any time the Depositary no longer is eligible under this Section 7.12, the
Regular Trustees shall appoint a successor Depositary with respect to the
Preferred Securities. If a successor Depositary is not appointed by the Trust
within 90 days after the Trust receives such notice or becomes aware of such
ineligibility, the Trust's election that the Preferred Securities be represented
by one or more Global Securities shall no longer be effective, and a Regular
Trustee shall execute, and the Property Trustee will

<PAGE>   71

authenticate and deliver, Preferred Securities in definitive registered form, in
any authorized denominations, in an aggregate stated liquidation amount equal to
the aggregate stated liquidation amount of the Global Securities representing
the Preferred Securities in exchange for such Global Securities.

                  A Regular Trustee on behalf of the Trust at any time and in
its sole discretion may determine that the Preferred Securities issued in the
form of one or more Global Securities shall no longer be represented by Global
Securities. In such event a Regular Trustee on behalf of the Trust shall
execute, and the Property Trustee shall authenticate and deliver, Preferred
Securities in definitive registered form, in any authorized denominations, in an
aggregate stated liquidation amount equal to the aggregate stated liquidation
amount of the Global Securities representing the Preferred Securities, in
exchange for such Global Securities.

                  Notwithstanding any other provisions of this Declaration
(other than the provisions set forth in Section 7.9), Global Securities may not
be transferred as a whole except by the Depositary to a nominee of the
Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary.

                  Interests of Beneficial Owners may be transferred or exchanged
for Preferred Securities not represented by a Global Security, and Preferred
Securities not represented by a Global Security may be transferred or exchanged
for a Global Security or Securities, in accordance with rules of the Depositary
and the provisions of Section 7.9.

         Section 7.13      Remarketing.

         (a) So long as the Preferred Securities, the PEPS Units and the
Treasury Securities are evidenced by one or more global certificates held by the
Depositary, the Subordinated Deferrable Notes Issuer shall request, not later
than 15 nor more than 30 calendar days prior to the Remarketing Date, that the
Depositary notify the Holders of the Preferred Securities and the holders of
PEPS Units and the Treasury PEPS Units of the Remarketing and of the procedures
that must be followed if a Holder of Preferred Securities wishes to make a Cash
Settlement.

         (b) Not later than 5:00 P.M., New York City time, on the seventh
Business Day preceding August 18, 2003, each Holder of Preferred Securities may
elect to have the Preferred Securities held by such Holder remarketed in the

<PAGE>   72

Remarketing. Under Section 5.02 of the Purchase Contract Agreement, holders of
PEPS Units that do not give notice of their intention to make a Cash Settlement
(that is not a Cash Merger Early Settlement) of the Purchase Contract component
of their PEPS Units prior to such time in the manner specified in such Section,
or have given such notice but fail to deliver cash prior to 11:00 A.M., New York
City time, on or prior to the fifth Business Day preceding August 18, 2003,
shall be deemed to have consented to the disposition of the Preferred Securities
comprising a component of their PEPS Units in the Remarketing. Holders of the
Preferred Securities that are not a component of PEPS Units wishing to elect to
have their Preferred Securities remarketed shall give to the Property Trustee
notice of their election prior to 11:00 A.M., New York City time on the fifth
Business Day prior to August 18, 2003. Any such notice shall be irrevocable and
may not be conditioned upon the level at which the Reset Rate is established in
the Remarketing. Promptly after 11:00 A.M., New York City time, on such fifth
Business Day, the Property Trustee, based on the notices received by it prior to
such time (including notices from the Purchase Contract Agent as to Purchase
Contracts for which Cash Settlement has been elected and cash received), shall
notify the Trust, the Sponsor and the Remarketing Agent of the number of
Preferred Securities to be tendered for purchase in the Remarketing.

         (c) If any Holder of PEPS Units does not give a notice of its intention
to make a Cash Settlement (that is not a Cash Merger Early Settlement) or gives
such notice but fails to deliver cash as described in Section 7.13(b), or gives
a notice of election to have Preferred Securities that are not a component of
PEPS Units remarketed, then the Preferred Securities of such Holder shall be
deemed tendered for purchase in the Remarketing, notwithstanding any failure by
such Holder to deliver or properly deliver such Preferred Securities to the
Remarketing Agent for purchase.

         (d) The right of each Holder to have Preferred Securities tendered for
purchase shall be limited to the extent that (i) the Remarketing Agent conducts
a Remarketing pursuant to the terms of the Remarketing Agreement, (ii) the
Remarketing Agent is able to find a purchaser or purchasers for the tendered
Preferred Securities and (iii) such purchaser or purchasers deliver the purchase
price therefor to the Remarketing Agent.

         (e) On the Remarketing Date, the Remarketing Agent shall use
commercially reasonable efforts to remarket, at a price equal to 100.50% of the
aggregate stated liquidation amount thereof, the Preferred Securities tendered
or deemed tendered for purchase.

         (f) If, as a result of the efforts described in 7.13(e), the
Remarketing Agent has determined that it will not be able to remarket all of the
Preferred Securities tendered or deemed tendered for purchase at a price of
100.50% of the aggregate stated liquidation amount of such Preferred Securities,
the Remarketing Agent shall determine the Reset Rate, which shall be the rate
per annum (rounded to

<PAGE>   73

the nearest one-thousandth (0.001) of one percent per annum), adjusted up or
down, sufficient to cause the then current aggregate market value of the
Preferred Securities to be equal to 100.50% of the aggregate stated liquidation
amount of such Preferred Securities, that the Remarketing Agent determines, in
its sole reasonable judgment, to be the lowest rate per annum that will enable
it to remarket all of the Preferred Securities tendered or deemed tendered for
Remarketing.

         (g) If none of the Holders of the Preferred Securities or the holders
of the PEPS Units elect to have Preferred Securities remarketed in the
Remarketing, the Reset Rate shall be the rate determined by the Remarketing
Agent, in its sole reasonable discretion, as the rate that would have been
established had a Remarketing been held on the Remarketing Date.

         (h) If, by 4:00 P.M., New York City time, on the Remarketing Date, the
Remarketing Agent is unable to remarket all of the Preferred Securities tendered
or deemed tendered for purchase, a failed Remarketing ("Failed Remarketing")
shall be deemed to have occurred and the Remarketing Agent shall so advise by
telephone the Depositary, the Property Trustee, the Trust and the Sponsor. In
the event of a Failed Remarketing, the Reset Rate shall equal the Two-Year
Benchmark Treasury Rate plus the Applicable Margin.

         (i) By approximately 4:30 P.M., New York City time, on the Remarketing
Date provided that there has not been a Failed Remarketing, the Remarketing
Agent shall advise, by telephone (i) the Depositary, the Property Trustee, the
Trust and the Sponsor of the Reset Rate determined in the Remarketing and the
number of Preferred Securities sold in the Remarketing, (ii) each purchaser (or
the Depositary Participant thereof) purchasing Preferred Securities sold in the
Remarketing of the Reset Rate and the number of Preferred Securities such
purchaser is to purchase and (iii) each purchaser to give instructions to its
Depositary Participant to pay the purchase price on the Purchase Contract
Settlement Date in same day funds against delivery of the Preferred Securities
purchased through the facilities of the Depositary.

         (j) In accordance with the Depositary's normal procedures, on the
Remarketing Settlement Date, the transactions described above with respect to
each Preferred Security tendered for purchase and sold in the Remarketing shall
be executed through the Depositary, and the accounts of the respective
Depositary Participants shall be debited and credited and such Preferred
Securities delivered by book-entry as necessary to effect purchases and sales of
such Preferred Securities. The Depositary shall make payment in accordance with
its normal procedures.

<PAGE>   74

         (k) If any Holder of the Preferred Securities selling Preferred
Securities in the Remarketing fails to deliver such Preferred Securities, the
Depositary Participant of such selling Holder and of any other Person that was
to have purchased Preferred Securities in the Remarketing may deliver to any
such other Person a number of Preferred Securities that is less than the number
of Preferred Securities that otherwise was to be purchased by such Person. In
such event, the number of Preferred Securities to be so delivered shall be
determined by such Depositary Participant, and delivery of such lesser number of
Preferred Securities shall constitute good delivery.

         (l) The Remarketing Agent is not obligated to purchase any Preferred
Securities that otherwise would remain unsold in the Remarketing. None of the
Trust, any Trustee, the Sponsor or the Remarketing Agent shall be obligated in
any case to provide funds to make payment upon tender of the Preferred
Securities for Remarketing.

         (m) Under the Remarketing Agreement, the Sponsor, in its capacity as
Subordinated Deferrable Notes Issuer, shall be liable for, and shall pay, any
and all costs and expenses incurred in connection with the Remarketing, and the
Trust shall not have any liabilities for such costs and expenses; provided,
however, that for the performance of its services, the Remarketing Agent will
retain from the proceeds of the Remarketing an amount equal to 0.50% of the
aggregate stated liquidation amount of all remarketed Preferred Securities.

         (n) The tender and settlement procedures set in this Section 7.13,
including provisions for payment by purchasers of the Preferred Securities in
the Remarketing, shall be subject to modification to the extent required by the
Depositary or if the book-entry system is no longer available for the Preferred
Securities at the time of the Remarketing, to facilitate the tendering and
remarketing of the Preferred Securities in certificated form. In addition, the
Remarketing Agent may modify the settlement procedures set forth herein in order
to facilitate the settlement process.

         Section 8.1       Dissolution and Termination of the Trust.

         (a)      The Trust shall dissolve upon the earliest of:

         by which Holders may exchange Certificates for Subordinated Deferrable
         Notes, or if Section 8.2(d) applies receive a distribution, as the
         Property Trustee shall deem appropriate.

         (c) Except where Section 8.1(a)(iv) or (v) or Section 8.2(d) applies,
in order to affect the liquidation of the Trust and distribution of the Notes to
Holders, the Property Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the date of the
Liquidation) and, either itself acting as exchange agent or through the
appointment of a separate exchange agent, shall establish such procedures as it
shall deem appropriate to effect the distribution of Subordinated Deferrable
Notes in exchange for the outstanding Certificates.

         (d) In the event that, notwithstanding the other provisions of this
Section 8.2, whether because of an order for dissolution entered by a court of
competent

<PAGE>   77

jurisdiction or otherwise, distribution of the Subordinated Deferrable Notes in
the manner provided herein is determined by the Property Trustee not to be
practical, the property of the Trust shall be liquidated, and the Trust shall be
wound-up and terminated, by the Property Trustee in such manner as the Property
Trustee reason ably determines. In such event, on the date of the winding-up and
termination of the Trust, the Holders of the Securities on the date of the
Liquidation shall be entitled to receive, out of the assets of the Trust
available for distribution to the Holders of the Securities after satisfaction
of the Trust's liabilities to creditors, if any, cash or other immediately
available funds in an amount equal to the aggregate of the stated liquidation
amount of $25 per Security plus accumulated and unpaid Distributions thereon to
the date of payment (such amount being the "Liquidation Distribution"); provided
if the Liquidation occurs prior to the Purchase Contract Settlement Date, the
Redemption Price payable to the Collateral Agent, in liquidation of the Holders'
interests in the Preferred Securities, will be distributed to the Collateral
Agent, which in turn will apply an amount equal to the Redemption Amount of such
Redemption Price to purchase the Treasury Portfolio on behalf of the Holders of
the Securities and remit the remaining portion, if any, of such Redemption Price
to the Purchase Contract Agent for payment to the Holders. If, upon any such
Liquidation, the Liquidation Distribution can be paid only in part because the
Trust has insufficient assets available to pay the aggregate Liquidation
Distribution in full, then the amounts payable directly by the Trust on the
Securities shall be paid on a Pro Rata basis. The Holders of the Common
Securities shall be entitled to receive the Liquidation Distribution Pro Rata
with the Holders of the Preferred Securities, except that if an Indenture Event
of Default has occurred and is continuing, then the Preferred Securities shall
have a preference over the Common Securities with regard to the Liquidation
Distribution.

         (e) After the date fixed for any distribution of Subordinated
Deferrable Notes upon dissolution of the Trust, (i) the Securities no longer
shall be deemed to be outstanding and (ii) the Certificates shall be deemed to
represent the Subordinated Deferrable Notes in a principal amount equal to the
stated liquidation amount of the Securities, bearing accrued and unpaid interest
in an amount equal to the accumulated and unpaid Distributions on the
Securities, until such Certificates are presented to the Regular Trustees or
agent for transfer or reissuance.

         (a) Except as expressly set forth in this Declaration and the
Guarantee, the Sponsor and the Trustees:

                  (i) shall not be personally liable for the return of any
         portion of the

<PAGE>   78

         capital contributions (or any return thereon) of the Holders of the
         Securities that will be made solely from assets of the Trust; and

                  (ii) shall not be required to pay to the Trust or to any
         Holder of the Securities any deficit, upon dissolution of the Trust or
         otherwise.

         (b) Pursuant to Section 3803(a) of the Business Trust Act, the Holder
of the Common Securities shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware; provided that the
Holders of the Common Securities shall be liable for all of the debts and
obligations of the Trust (other than with respect to the Securities) to the
extent such debts and obligations are not satisfied out of the Trust's assets.

         (c) Pursuant to Section 3803(a) of the Business Trust Act, the Holder
of the Preferred Securities shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware.

         Section 9.2       Exculpation.

         (a) No Indemnified Person shall be liable, responsible or accountable
in damages or otherwise to the Trust or to any Covered Person for any loss,
damage or claim incurred by reason of any act or omission performed or omitted
by such Indemnified Person in good faith on behalf of the Trust and in a manner
that such Indemnified Person reasonably believed to be within the scope of the
authority conferred on such Indemnified Person by this Declaration or by law,
except that an Indemnified Person shall be liable for any such loss, damage or
claim incurred by reason of such Indemnified Person's gross negligence (or, in
the case of the Property Trustee, negligence) or willful misconduct with respect
to such acts or omissions.

         (b) Each Indemnified Person shall be fully protected in relying in good
faith upon the records of the Trust and upon such information, opinions, reports
or statements presented to the Trust by any Person as to matters such
Indemnified Person reasonably believes to be within such other Person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Trust, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses or any other facts pertinent to the existence and amount of assets from
which distributions to Holders of the Securities might properly be paid.

         Section 9.3       Fiduciary Duty.

         (a) To the extent that, at law or in equity, an Indemnified Person has
duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to any other Covered Person, an Indemnified Person acting under this
Declaration shall not be liable to the Trust or to any other Covered Person for
its good faith reliance on the provisions of this Declaration. The provisions of
this Declaration, to the extent that they restrict the duties and liabilities of
an Indemnified Person otherwise existing at law or in equity (other than the
duties imposed on the Property Trustee under the Trust Indenture Act), are
agreed by the parties hereto to replace such other duties and liabilities of
such Indemnified Person.

         (b) Unless otherwise expressly provided herein:

                  (i) whenever a conflict of interest exists or arises between a
         Covered Person and an Indemnified Person; or

                  (ii) whenever this Declaration or any other agreement
         contemplated herein or therein provides that an Indemnified Person
         shall act in a manner that is, or provides terms that are, fair and
         reasonable to the Trust or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices and any applicable generally accepted accounting
practices or principles. In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Declaration or any other agreement
contemplated herein or of any duty or obligation of the Indemnified Person at
law or in equity or otherwise.

         (c) Whenever in this Declaration an Indemnified Person is permitted or
required to make a decision:

             (i) in its "discretion" or under a grant of similar authority, the
         Indemnified Person shall be entitled to consider such interests and
         factors as it desires, including its own interests, and shall have no
         duty or obligation to give any consideration to any interest of or
         factors affecting the Trust or any other Person; or

             (ii) in its "good faith" or under another express standard, the
         Indemnified Person shall act under such express standard and shall not
         be

<PAGE>   80

         subject to any other or different standard imposed by this Declaration
         or by applicable law.

         Section 9.4       Indemnification.

         (a) To the fullest extent permitted by applicable law, the Sponsor, in
its capacity as Subordinated Deferrable Notes Issuer, shall indemnify and hold
harmless each Indemnified Person from and against any loss, damage or claim
incurred by such Indemnified Person by reason of any act or omission performed
or omitted by such Indemnified Person in good faith on behalf of the Trust and
in a manner such Indemnified Person reasonably believed to be within the scope
of authority conferred on such Indemnified Person by this Declaration, except
that no Indemnified Person shall be entitled to be indemnified in respect of any
loss, damage or claim incurred by such Indemnified Person by reason of gross
negligence (or, in the case of the Property Trustee, negligence) or willful
misconduct with respect to such acts or omissions.

         (b) The provisions of this Section 9.4 shall survive the termination of
this Declaration or the resignation or removal of any Trustee.

         (c) The Sponsor or the Trust may purchase and maintain insurance on
behalf of any Person who is or was an Indemnified Person against any liability
asserted against him or her and incurred by him or her in any such capacity, or
arising out of his or her status as such, whether or not the Sponsor would have
the power to indemnify him or her against such liability under the provisions of
this Section 9.4.

         (d) For purposes of this Section 9.4, references to "the Trust" shall
include, in addition to the resulting or surviving entity, any constituent
entity (including any constituent of a constituent) absorbed in a consolidation
or merger, so that any Person who is or was a director, trustee, officer or
employee of such constituent entity, or is or was serving at the request of such
constituent entity as a director, trustee, officer, employee or agent of another
entity, shall stand in the same position under the provisions of this Section
9.4 with respect to the resulting or surviving entity as he or she would have
had with respect to such constituent entity if its separate existence had
continued.

         (e) The indemnification and advancement of expenses provided by, or
granted pursuant to, this Section 9.4 shall continue, unless otherwise provided
when authorized or ratified, as to a Person who has ceased to be an Indemnified
Person and shall inure to the benefit of the heirs, executors and administrators
of such a Person.

         Section 9.5       Outside Businesses.

                  Any Covered Person, the Sponsor, the Delaware Trustee and the
Property Trustee (subject to Section 6.3(c)) may engage in or possess an
interest in other business ventures of any nature or description, independently
or with others, similar or dissimilar to the activities of the Trust, and the
Trust and the Holders of the Securities shall have no rights by virtue of this
Declaration in and to such independent ventures or the income or profits derived
therefrom, and the pursuit of any such venture, even if competitive with the
activities of the Trust, shall not be deemed wrongful or improper. Each Covered
Person, the Sponsor, the Delaware Trustee and the Property Trustee shall not be
obligated to present any particular investment or other opportunity to the Trust
even if such opportunity is of a character that, if presented to the Trust,
could be taken by the Trust, and any Covered Person, the Sponsor, the Delaware
Trustee and the Property Trustee shall have the right to take for its own
account (individually or as a partner or fiduciary) or to recommend to others
any such particular investment or other opportunity. Any Covered Person, the
Delaware Trustee and the Property Trustee may engage or be interested in any
financial or other transaction with the Sponsor or any Affiliate of the Sponsor,
or may act as depositary for, trustee or agent for, or act on any committee or
body of holders of, securities or other obligations of the Sponsor or its
Affiliates.

                             ARTICLE 10: ACCOUNTING

         Section 10.1      Fiscal Year.

                  The fiscal year ("Fiscal Year") of the Trust shall be the
calendar year, or such other year as is required by the Code.

         Section 10.2      Certain Accounting Matters.

         (a) At all times during the existence of the Trust, the Regular
Trustees shall keep, or shall cause to be kept, full books of account, records
and supporting documents, which shall reflect in reasonable detail each
transaction of the Trust. The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied. The Trust shall use the accrual method of
accounting for United States federal income tax purposes. The books of account
and the records of the Trust shall be examined by and reported upon as of the
end of each Fiscal Year of the Trust by a firm of independent certified public
accountants selected by the Regular Trustees.

<PAGE>   82

         (b) The Regular Trustees shall cause to be prepared and delivered to
each Holder of Securities, within 90 days after the end of each Fiscal Year of
the Trust, annual financial statements of the Trust, including a balance sheet
of the Trust as of the end of such Fiscal Year, and the related statements of
income or loss.

         (c) The Regular Trustees shall cause to be duly prepared and delivered
to each Holder of Securities an annual United States federal income tax
information statement, required by the Code, containing such information with
regard to the Securities held by each Holder as is required by the Code and the
Treasury Regulations. Notwithstanding any right under the Code to deliver any
such statement at a later date, the Regular Trustees shall endeavor to deliver
all such statements within 30 days after the end of each Fiscal Year of the
Trust.

         (d) The Regular Trustees shall cause to be duly prepared and filed with
the appropriate taxing authority an annual United States federal income tax
return, on Form 1041 or such other form required by United States federal income
tax law, and any other annual income tax returns required to be filed on behalf
of the Trust with any state or local taxing authority.

         Section 10.3      Banking.

                  The Trust shall maintain one or more bank accounts in the name
and for the sole benefit of the Trust; provided that all payments of funds in
respect of the Subordinated Deferrable Notes held by the Property Trustee shall
be made directly to the Property Account and no other funds of the Trust shall
be deposited in the Property Account. The sole signatories for such accounts
shall be designated by the Regular Trustees; provided that the Property Trustee
shall designate the signatories for the Property Account.

         Section 10.4      Withholding.

                  The Trust and the Regular Trustees shall comply with all
withholding requirements under United States federal, state and local law. The
Regular Trustees shall request, and the Holders of the Securities shall provide
to the Trust, such forms or certificates as are necessary to establish an
exemption from withholding with respect to each Holder of Securities and any
representations and forms as shall reasonably be requested by the Regular
Trustees to assist them in determining the extent of, and in fulfilling, the
Trust's withholding obligations. The Regular Trustees shall file required form
with applicable jurisdictions and, unless an exemption from withholding is
properly established by a Holder of Securities, shall remit amounts withheld
with respect to such Holder to applicable jurisdictions. To the extent that the
Trust is required to withhold and pay over any amounts to any authority with
respect to distributions or allocations to any Holder of Securities, the amount
withheld shall be deemed to be a distribution in the amount of the withholding
to such

<PAGE>   83

Holder. In the event of any claimed over withholding, a Holder shall be limited
to an action against the applicable jurisdiction. If the amount required to be
withheld was not withheld from actual Distributions made, the Trust may reduce
subsequent Distributions by the amount of such withholding.

         Section 11.1      Amendments.

         to, the terms of this Declaration (including the terms of the
         Securities);

             (ii) unless, in the case of any proposed amendment that affects the

                                    income tax purposes;

                           (B)      reduce or otherwise adversely affect the

                           (C)      cause the Trust to be deemed to be an
                                    Investment Company required to be registered
                                    under the Investment Company Act.

         (c) At such time after the Trust has issued any Securities that remain
outstanding, (i) any amendment that would (A) adversely affect the powers,
preferences or special rights of the Securities, whether by way of amendment to
this Declaration or otherwise or (B) result in the dissolution, winding-up or
termination of the Trust other than pursuant to the terms of this Declaration
shall not be effective except with the approval of the Holders of at least a 66
2/3% in Liquidation Amount of the Securities; provided that if any amendment or
proposal referred to in clause (A) above would adversely affect only the
Preferred Securities or the Common Securities, then only the affected class will
be entitled to vote on such amendment or proposal, and such amendment or
proposal shall not be effective except with the approval of a 66 2/3% in
Liquidation Amount of the class of Securities affected thereby; and (ii) any
amendment that would (X) change the amount or timing of any distribution of the
Securities or otherwise adversely affect the amount of any distribution require
to be made in respect of the Securities as of a specified date or (Y) restrict

such payment on or after such date shall not be effective except with the

without the consent of the Holders of the Securities, provided that such
amendment does not have a material adverse effect on the rights, preferences or
privileges of the

<PAGE>   85

Holders of the Securities:

                  (i) to cure any ambiguity;

                  (ii) to correct or supplement any provision in this
         Declaration that may be defective or inconsistent with any other
         provision of this Declaration;

         the Sponsor;

                  (iv) to conform to any change in Rule 3a-5 or written change
         in interpretation or application of Rule 3a-5 by any legislative body,
         court, government agency or regulatory authority;

                  (v) to modify, eliminate and add to any provision of this
         Declaration to ensure that the Trust will be classified as a grantor
         trust for United States federal income tax purposes at all times that
         any Securities are out standing or to ensure that the Trust will not be
         required to register as an Investment Company under the Investment
         Company Act; provided that such modification, elimination or addition
         would not adversely affect in any material respect the rights,
         privileges or preferences of any Holder of Securities; or

                  (vi) to facilitate the tendering, remarketing and settlement
         of the Preferred Securities as contemplated by Section 7.13(n).

         Section 11.2 Meetings of the Holders of the Securities; Action by
Written Consent.

         (a) Meetings of the Holders of any class of Securities may be called at
any time by the Regular Trustees (or as provided in the terms of the Securities)
to consider and act on any matter on which Holders of such class of Securities
are entitled to act under the terms of this Declaration or the rules of any
stock exchange on which the Preferred Securities are listed or admitted for
trading. The Regular Trustees shall call a meeting of the Holders of such class
if directed to do so by the Holders of at least 10% in Liquidation Amount of
such class of Securities. Such direction shall be given by delivering to the
Regular Trustees a writing stating that the signing Holders of the Securities
wish to call a meeting and indicating the general or specific purpose for which
the meeting is to be called. The Holder or Holders of the Securities calling a
meeting shall specify in writing the Certificates held by such

<PAGE>   86

Holder or Holders, and only those Securities specified shall be counted for
purposes of determining whether the required percentage set forth in the second
sentence of this paragraph has been met.

         (b) Except to the extent otherwise provided in the terms of the
Securities, the following provisions shall apply to meetings of the Holders of
the Securities:

             (i) Notice of any such meeting shall be given to all the Holders of
         the Securities having a right to vote thereat at least seven days and
         not more than 60 days before the date of such meeting. Whenever a vote,
         consent or approval of the Holders of the Securities is permitted or
         required under this Declaration or the rules of any stock exchange on
         which the Preferred Securities are listed or admitted for trading, such
         vote, consent or approval may be given at a meeting of the Holders of
         the Securities. Any action that may be taken at a meeting of the
         Holders of the Securities may be taken without a meeting and without
         prior notice if a consent in writing setting forth the action so taken
         is signed by the Holders of the Securities owning not less than the
         minimum amount of Securities in liquidation amount that would be
         necessary to authorize or take such action at a meeting at which all
         Holders of the Securities having a right to vote thereon were present
         and voting. Prompt notice of the taking of action without a meeting
         shall be given to the Holders of the Securities entitled to vote who
         have not consented in writing. The Regular Trustees may specify that
         any written ballot submitted to the Holders of the Securities for the
         purpose of taking any action without a meeting shall be returned to the
         Trust within the time specified by the Regular Trustees.

             (ii) Each Holder of the Securities may authorize any Person to act
         for it by proxy on any or all matters in which such Holder is entitled
         to participate, including waiving notice of any meeting, or voting or
         participating at a meeting. No proxy shall be valid after the
         expiration of 11 months from the date thereof unless otherwise provided
         in the proxy. Every proxy shall be revocable at the pleasure of the
         Holder of Securities executing such proxy. Except as otherwise provided
         herein, all matters relating to the giving, voting or validity of
         proxies shall be governed by the General Corporation Law of the State
         of Delaware relating to proxies, and judicial interpretations
         thereunder, as if the Trust were a Delaware corporation and the Holders
         of the Securities were stockholders of a Delaware corporation.

             (iii) Each meeting of the Holders of the Securities shall be
         conducted by the Regular Trustees or by such other Person that the
         Regular Trustees may designate.

             (iv) Unless the Business Trust Act, this Declaration, the Trust
         Indenture Act or the listing rules of any stock exchange on which the

<PAGE>   87
         Preferred Securities are then listed for trading otherwise provides,
         the Regular Trustees, in their sole discretion, shall establish all
         other provisions relating to meetings of Holders of the Securities,
         including notice of the time, place or purpose of any meeting at which
         any matter is to be voted on by any Holders of the Securities, waiver
         of any such notice, action by consent without a meeting without prior
         notice, the establishment of a record date, quorum requirements, voting
         in person or by proxy or any other matter with respect to the exercise
         of any such right to vote.
