                                       AND
                              DTE ENTERPRISES, INC.

         Agreement dated as of December 13, 2001 (this "Agreement"), made by and
between DTE Energy Company (the "Parent"), a corporation incorporated under the
laws of the State of Michigan, and DTE Enterprises, Inc. (the "Subsidiary"), a
corporation incorporated under the laws of the State of Michigan.

         WHEREAS, on May 31, 2001, the Parent completed the acquisition of MCN
Energy Group Inc. ("MCN"), and thereafter merged MCN into the Subsidiary with
the Subsidiary being the surviving company; and

         WHEREAS, the Parent is the direct parent and owner of 100% of the
outstanding common stock of the Subsidiary; and

         WHEREAS, MCN, prior to the merger, had issued the debentures listed in
Attachment A hereto, (the "Debt Securities"); and

         WHEREAS, MCN Financing I, MCN Financing II, MCN Financing III, and MCN
Michigan Ltd. Partnership, as special purpose financing vehicles (the "Financing
Companies") sponsored by MCN, had issued, prior to the merger, the preferred
securities and common securities, if any, together with MCN's guarantees of such
preferred and common securities listed in Attachment B hereto (the guarantees of
such preferred and common securities, hereinafter "Securities Guarantees"); and

         WHEREAS, under the Securities Guarantees, MCN irrevocably and
unconditionally agreed, to the extent set forth in such agreements, to guarantee
the obligations of the Financing Companies to the holders of their securities on
the terms and conditions set forth in such guarantee agreements; and

         WHEREAS, by operation of law the Subsidiary succeeded to and assumed
all of the rights, duties and obligations of MCN; and

         WHEREAS, the Parent desires irrevocably and unconditionally to agree,
to the extent set forth in this Agreement, to support, on a joint and several
basis with the Subsidiary (i) the obligations of Subsidiary under the terms of
the Debt Securities and (ii) the obligations under the preferred securities and
common securities of the Financing Companies to the extent set forth in the
Securities Guarantees (Debt Securities and Securities Guarantees, collectively
"Securities");

         NOW THEREFORE, in consideration of the foregoing premises, and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Parent

<PAGE>

hereby agrees as follows (a reference to the singular includes the plural and
vice versa, and capitalized terms used in this Agreement but not defined in the
preamble above have the respective meanings assigned to them in this Agreement):

            Section 1. Payment Provision. If, during the term of this Agreement,
the Subsidiary fails to make any scheduled payment of interest, principal or
premium, if any, or any other payment under the terms and provisions of the
Securities, Parent shall be obligated, to the fullest extent permitted by law to
either make, or cause Subsidiary to make, the scheduled payment immediately
following notice of such failure (the obligations set forth in this Section 1
being herein called the "Supported Obligations"). The obligation hereunder is
full and unconditional.

            Section 2. Remedies. The Parent agrees that if Subsidiary defaults
in the timely payment of any Supported Obligations when due, the holder of a
Security may proceed directly against Parent to obtain payment of such defaulted
Supported Obligation owed to such holder.

            Section 3. Payment on Demand. The Parent shall make payment of the
amount of the Supported Obligations and all other amounts payable by it to the
holder of the Security after demand therefor is made in writing to it. Such
demand shall be deemed to have been effectively made when either an envelope
containing such demand is addressed to Parent at 2000 2nd Ave, Detroit, Michigan
48226-1279 for the attention of the Treasurer, or is personally delivered to
such address, or a facsimile transmission containing such demand is sent to
Parent, for the attention of the Treasurer, at the following fax number: (313)
235-8741.

            Section 4. Subrogation. Upon receipt by a holder of any payment or
payments on account of liability under this Agreement, the Parent shall not be
entitled to claim repayment against the Subsidiary until the claims of the
holders against the Subsidiary in respect of the defaulted Supported Obligations
have been repaid in full. If any amount shall be paid to the Parent on account
of any subrogation rights at any time when all the defaulted Supported
Obligations shall not have been paid in full, such amount shall be held in trust
for the benefit of the holders of the defaulted Security and shall be paid to
the holders of the defaulted Security.

            Section 5. Waivers. The Parent hereby waives any failure or delay on
the part of Subsidiary in asserting or enforcing any of its rights or in making
any claims or demands hereunder. Subsidiary, any holder of a Security, or any
trustee of a Security, may at any time, without Parent's consent, without notice
to Parent and without affecting or impairing Subsidiary's or such holders or
trustee's rights or Parent's obligations hereunder, do any of the following with
respect to the Securities: (a) make changes, modifications, amendments or
alterations, by operation of law or otherwise, (b) grant renewals and extensions
of time, for payment or otherwise, (c) accept new or additional documents,
instruments or agreements relating to or in substitution of the Securities, or
(d) otherwise handle the enforcement of their respective rights and remedies in
accordance with their business judgment.

            Section 6. Amendment.

            (a)   With the written consent of the holders of a majority in
                  principal amount of the outstanding Securities, this Agreement
                  may be amended to add any provisions or change or eliminate
                  any provisions of this Agreement, or modify in each case in
                  any manner, the rights of the holders of the Securities under
                  this Agreement. The holders of a majority in principal amount
                  of the outstanding Securities affected by such waiver, by
                  notice to the trustee of the applicable Securities, may waive
                  compliance by the Parent with any provision of this Agreement;
                  provided, however, without the consent of each holder of
                  Securities affected, an amendment or waiver may not (i) reduce
                  the amount of Securities whose holders must consent to an
                  amendment or waiver or (ii) make any changes in Section 1; and

            (b)   Notwithstanding the provisions of Section 6(a), the Parent may
                  amend this Agreement to cure any ambiguity, defect or
                  inconsistency herein or to make any other change; provided,
                  however, no such action shall adversely affect the rights of
                  any holder of Securities.

            Section 7. Reinstatement. This Agreement shall continue to be
effective or be reinstated, as the case may be, if at any time any payment of
any of the Supported Obligations is rescinded or must otherwise be refunded by
the holders of Securities upon the insolvency, bankruptcy or reorganization of
the Subsidiary or otherwise, regardless of whether the holders of Securities
contested the order requiring the return of such payment, all as though such
payment had not been made.

            Section 8. No Recourse. Any right of subrogation acquired by the
Parent by reason of payment under or pursuant to this Agreement shall not be
exercised until the Supported Obligations and other amounts due to the holders
of Securities hereunder have been paid or repaid in full and shall be no greater
than the right held by the holders of Securities, and the Parent shall have no
recourse against the holders of Securities for any irregularity or defect in the
manner or procedure by which the holders of Securities make demand or pursue any
rights or remedies they may have.

            Section 9. Representations and Warranties. The Parent represents and
warrants that:

            a)    Organization and Qualification. It is a corporation duly
                  incorporated and validly existing under the laws of the State
                  of Michigan.

            b)    Corporate Power. It has full corporate right, power and
                  authority to own its property and assets and to carry on its
                  business as now conducted and as contemplated to be conducted
                  and to enter into and perform this Agreement.

            c)    Conflict with Other Instruments. Neither the execution and
                  delivery of this Agreement nor the consummation of the
                  transactions herein contemplated nor compliance with the
                  terms, conditions and provisions hereof (i) conflicts with or

                                       3

                  results in a breach of any of the terms, conditions or
                  provisions of (A) its charter documents or by-laws; (B) any
                  material law, rule or regulation having the force of law; (C)
                  any material contractual restriction binding on or affecting
                  it or its properties; or (D) any material judgment,
                  injunction, determination or award which is binding on it; or
                  (ii) results in, or requires the creation or imposition of any
                  lien upon or security interest in or with respect to the
                  properties now owned or hereafter acquired by it under any
                  contractual provision binding on or affecting it.

         d)       Authorization, Governmental Approvals, etc. The execution and
                  delivery of this Agreement and the consummation by it of the
                  transactions herein contemplated have been duly authorized by
                  all necessary corporate action and no authorization, consent,
                  approval, license or exemption under any applicable law, rule
                  or regulation having the force of law, and no registration,
                  qualification, designation, declaration, recording, or filing
                  with any official body, is or was necessary therefor or to
                  perfect the same or to preserve the benefit thereof to the
                  holders of the Securities, except such as are in full force
                  and effect at the date hereof.

         e)       Execution and Binding Obligation. This Agreement has been duly
                  executed and delivered by it, and constitutes the legal, valid
                  and binding obligation of it enforceable against it in
                  accordance with its terms, subject to the effect of any
                  applicable bankruptcy, fraudulent conveyance, insolvency,
                  reorganization, moratorium or similar laws affecting
                  creditors' rights generally and the effect of general
                  principles of equity (regardless of whether such
                  enforceability is considered in a proceeding in equity or at
                  law).

         f)       Actions. There is no pending or threatened action or
                  proceeding affecting it before any court, governmental agency
                  or arbitrator, which may materially adversely affect its
                  financial condition or operations or impair the ability of the
                  Parent to perform its obligations under this Agreement. The
                  Parent is not in default with respect to any order of any
                  court, governmental authority or arbitrator, the effect of
                  which would have a material adverse effect on the Parent and
                  its subsidiaries on a consolidated basis.

         g)       Shares. The Parent is the registered and beneficial holder of
                  100% of the issued and outstanding shares of common stock of
                  the Subsidiary.

         Section 10. Governing Law. (a) This Agreement shall be governed by and
construed in accordance with the laws of the State of Michigan.

         Section 11. Headings, Etc. The division of this Agreement into sections
and the insertion of headings are for convenience of reference only and shall
not affect the interpretation hereof.

         Section 12. Severability. Any provision of this Agreement which is
invalid or not enforceable shall not affect any other provision and shall be
deemed to be severable.

         Section 13. Successors and Assigns. This Agreement shall extend to and
inure to the benefit of the trustee of the Securities and the holders of the
Securities and their respective successors and assigns.

                                       5
<PAGE>
         With respect to the Debentures, (i) references elsewhere in the
Original Indenture to Section 501(4), (6) or (7) shall be deemed to be Section
501(3), (4) or (5), respectively, as restated above, and (ii) the provisions of
Section 502 of the Original Indenture, without limitation, shall be subject to
the subordination provisions relating to the Debentures.

         (c) The following shall be additional covenants of the Company with
respect to the Debentures:

                  (i) In the event that the Property Trustee is the holder of
         all of the Outstanding Debentures, the Company shall pay to the Trust
         (and any permitted successor or assign under the Agreement) for so long
         as the Trust (or its permitted successor or assignee) is the registered
         holder of any Debentures, such additional amounts as may be necessary
         in order that the amount of Distributions then due and payable by the
         Trust on the related Trust Preferred Securities and Common Securities
         that at any time remain outstanding in accordance with the terms
         thereof shall not be reduced as a result of any taxes, duties,
         assessments and governmental charges of whatever nature imposed by the
         United States or any other taxing authority to which the Trust has
         become subject as a result of such Tax Event (but not including
         withholding taxes imposed on holders of such Trust Preferred Securities
         and Common Securities) (the "Additional Interest"). Whenever in the
         Indenture or the Debentures there is a reference in any context to the
         payment of principal of or interest on the Debentures, such reference
         shall be deemed to include payment of the Additional Interest provided
         for in this paragraph to the extent that, in such context, Additional
         Interest is, were or would be payable in respect thereof pursuant to
         the provisions of this Section and express reference to the payment of
         Additional Interest (if applicable) in any provisions hereof shall not
         be construed as excluding Additional Interest in those provisions
         hereof where such express reference is not made.

                  (ii) The Company covenants and agrees with each holder of
         Debentures that it shall not

                           (A) 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;

                           (B) make any payment of principal of or premium or
                  interest on or repay, repurchase or redeem any indebtedness of
                  the Company that ranks equally with or junior in right of
                  payment to the Debentures;

                           (C) make any guarantee payments with respect to any
                  guarantee by the Company of the indebtedness of any Subsidiary
                  thereof or any other party if such guarantee ranks equally
                  with or junior in right of payment to the Debentures

                                       6
<PAGE>
                  (other than (a) dividends or distributions payable solely 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 Rights Plan, (c) the issuance of any
                  Capital Stock of the Company under any Rights Plan, or the
                  redemption or repurchase of any rights distributed pursuant to
                  a Rights Plan, (d) payments under the Trust Preferred
                  Securities Guarantee, (e) reclassification 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, (f) 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 (g) purchases of Common Stock related to the issuance of
                  Common Stock or rights under any of the Company's benefit
                  plans for its directors, officers, employees, consultants or
                  advisors or any of the Company's dividend reinvestment plans);

if at such time (x) there shall have occurred and be continuing an Event of
Default under the Debentures or any event of which the Company has actual
knowledge that is, or with the giving of notice or the lapse of time, or both,
would be an Event of Default under the Debentures, and the Company has not taken
reasonable steps to cure such Event of Default (y) the Company shall be in
default with respect to its payment or other obligations under the Trust
Preferred Securities Guarantee or (z) the Company shall have given notice of its
election to begin an Extension Period as provided in Section 205 and shall not
have rescinded such notice or such Extension Period, or any extension thereof,
shall have commenced and be continuing.

                  (iii) The Company also covenants with each holder of
         Debentures (A) to maintain directly or indirectly 100% ownership of the
         Common Securities of the Trust; provided, however, that any permitted
         successor or assignee of the Company hereunder may succeed to the
         Company's ownership of such Common Securities, (B) not to voluntarily
         terminate, wind up or liquidate the Trust, except (x) in connection
         with a prepayment in full of the Debentures or a distribution of the
         Debentures to the holders of Trust Preferred Securities in liquidation
         of the Trust or (y) in connection with certain mergers, consolidations
         or amalgamations permitted by the Agreement and (C) to use its
         commercially reasonable efforts, consistent with the terms and
         provisions of the Agreement, to cause the Trust to remain classified as
         a grantor trust and not an association taxable as a corporation for
         United States federal income tax purposes.

         (d) In addition to any right of Direct Action granted under Section
3.8(e) of the Agreement to the holders of Trust Preferred Securities, if the
Property Trustee fails to enforce its rights under the Agreement or the
Indenture to the fullest extent permitted by law and subject to the terms of the
Agreement and the Indenture, then a holder of Trust Preferred Securities may
directly institute a proceeding against the Company to enforce the Property
Trustee's rights

                                       7
<PAGE>
under the Agreement or the Indenture without first instituting a legal
proceeding against the Property Trustee or any other person.

         SECTION 203. Amount, Form and Denominations; DTC. (a) The aggregate
principal amount of Debentures that may be issued under this Supplemental
Indenture is limited to $185,567,025, which amount shall be as set forth in any
written Company Order for the authentication and delivery of Debentures (except
as provided in Section 301(2) of the Original Indenture). The Debentures shall
be issuable only in fully registered form and, as permitted by Section 301 and
Section 302 of the Original Indenture, issuable, transferable, exchangeable or
redeemable in denominations of $25 and integral multiples thereof.

         (b) The Debentures initially shall be issued to the Property Trustee.
Principal and interest on the Debentures issued in definitive form will be
payable, the transfer of such Debentures will be registrable and such Debentures
will be exchangeable for Debentures bearing identical terms and provisions at
the Corporate Trust Office; provided, however, that payment of interest may be
made at the option of the Company by check mailed to the registered holder at
such address as shall appear in the Security Register. Notwithstanding the
foregoing, so long as the registered holder of any Debentures is the Property
Trustee, the payment of the principal of and interest (including Compound
Interest and Additional Interest, if any) on such Debentures held by the
Property Trustee will be made at such place, or by wire transfer of immediately
available funds to such account, as may be designated by the Property Trustee.
The Security Register for the Debentures shall be kept at the Corporate Trust
Office, and the Trustee is hereby appointed Security Registrar for the
Debentures.

         (c) In connection with a Dissolution Event, the Debentures in
certificated form may be presented to the Trustee by the Property Trustee in
exchange for one or more global Debentures in an aggregate principal amount
equal to the aggregate principal amount of all outstanding Debentures (each, a
"Global Debenture"), to be registered in the name of the Depositary, or its
nominee, and delivered by the Trustee to the Depositary for crediting to the
accounts of its participants pursuant to the instructions of the Administrative
Trustees. The Company upon any such presentation shall execute a Global
Debenture or Debentures in such aggregate principal amount and deliver the same
to the Trustee for authentication and delivery in accordance with the Original
Indenture and this Supplemental Indenture. Payments on the Debentures issued as
a Global Debenture will be made to the Depositary. The Depository Trust Company,
as depository ("DTC"), or its nominee, is hereby designated as "U.S. Depositary"
and Depositary" under the Original Indenture for the Global Debenture.

         If any Trust Preferred Securities are held in non book-entry
certificated form, the Debentures in certificated form may be presented to the
Trustee by the Property Trustee and any Trust Preferred Security Certificate
which represents Trust Preferred Securities other than Trust Preferred
Securities held by the Depositary or its nominee ("Non Book-Entry Trust
Preferred Securities") will be deemed to represent beneficial interests in
Debentures presented to the Trustee by the Property Trustee having an aggregate
principal amount equal to the aggregate liquidation amount of the Non Book-Entry
Trust Preferred Securities until such Trust Preferred

                                       8
<PAGE>
Security Certificates are presented to the Security Registrar for transfer or
reissuance, at which time such Trust Preferred Security Certificates will be
canceled and a Debenture, registered in the name of the holder of the Trust
Preferred Security Certificate or the transferee of the holder of such Trust
Preferred Security Certificate, as the case may be, with an aggregate principal
amount equal to the aggregate liquidation amount of the Trust Preferred Security
Certificate canceled, will be executed by the Company and delivered to the
Trustee for authentication and delivery in accordance with the Original
Indenture and this Supplemental Indenture. On issue of such Debentures,
Debentures with an equivalent aggregate principal amount that were presented by
the Property Trustee to the Trustee will be deemed to have been canceled.

         (d) Further to Section 305 of the Original Indenture, any Global
Debenture shall be exchangeable for Debentures registered in the name of, and a
transfer of a Global Debenture may be registered to, any Person other than the
Depositary for such Debenture or its nominee only if (i) such Depositary
notifies the Company that it is unwilling or unable to continue as Depositary
for such Global Debenture or if at any time such Depositary ceases to be a
clearing agency registered under the Exchange Act, and, in either such case, the
Company does not appoint a successor Depositary within 90 days thereafter, (ii)
the Company executes and delivers to the Trustee a Company Order that such
Global Debenture shall be so exchangeable and the transfer thereof so
registrable or (iii) there shall have occurred and be continuing an Event of
Default or an event which, with the giving of notice or lapse of time, or both,
would constitute an Event of Default with respect to the Debentures. Upon the
occurrence in respect of any Global Debenture of any or more of the conditions
specified in clause (i), (ii) or (iii) of the preceding sentence, such Global
Debenture may be exchanged for Debentures registered in the name of, and the
transfer of such Global Debenture may be registered to, such Persons (including
Persons other than the Depositary with respect to such series and its nominees)
as such Depositary, in the case of an exchange, and the Company, in the case of
a transfer, shall direct.

         (e) Each Debenture issued hereunder shall provide that the Company and,
by its acceptance of a Debenture or a beneficial interest therein, the holder
of, and any Person that acquires a beneficial interest in, such Debenture agree
that for United States federal, state and local tax purposes it is intended that
such Debenture constitute indebtedness.

         (f) The Debentures shall have such other terms and provisions as are
set forth in the form of Debenture attached hereto as Exhibit A (all of which
incorporated by reference in and made a part of this Supplemental Indenture as
if set forth in full at this place).

         SECTION 204. Interest.

         (a) Each Debenture will bear interest at the rate of 7.8% per annum
(the "Coupon Rate") from and including the original date of issuance until the
principal thereof becomes due and payable, and on any overdue principal and, to
the extent that payment of such interest is enforceable under applicable law, on
any overdue installment of interest at the Coupon Rate, compounded quarterly,
payable quarterly in arrears on February 1, May 1, August 1 and November 1 of
each year (each, an "Interest Payment Date"), commencing on May 1, 2002 to

                                       9
<PAGE>
the Person in whose name such Debenture or any predecessor Debenture is
registered at the close of business on the relevant Regular Record Date, which
will be, (i) as long as the Trust Preferred Securities remain in book-entry form
(or if no Trust Preferred Securities remain outstanding, as long as the
Debentures remain in book-entry form), one Business Day prior to the relevant
Interest Payment Date and, (ii) in the event the Trust Preferred Securities are
not in book-entry form (or if no Trust Preferred Securities remain outstanding,
in the event the Debentures are not in book-entry form), the Administrative
Trustees (or, if no Trust Preferred Securities remain outstanding, the Company)
will have the right to select the Regular Record Date, which will be more than
one Business Day but less than 60 Business Days prior to the relevant Interest
Payment Date, except as otherwise provided pursuant to the provisions of Section
205 below.

         Any such interest installment not punctually paid or duly provided for
shall forthwith cease to be payable to the registered Holders on the Regular
Record Date, and may either be paid to the person in whose name the Debenture
(or one or more Predecessor Securities) is registered at the close of business
on a Special Record Date to be fixed by the Trustee for the payment of such
defaulted interest, notice whereof shall be given to the registered Holders of
this series of Debentures not less than ten 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 Debentures may be
listed, and upon such notice as may be required by such exchange, all as more
fully provided in the Original Indenture. The principal of and the interest on
the Debentures shall be payable at the office or agency of the Company
maintained for that purpose in the Borough of Manhattan, The City of New York,
in any coin or currency of the United States of America which at the time of
payment is legal tender for payment of public and private debts; provided,
however, that payment of interest may be made at the option of the Company by
check mailed to the registered Holder at the close of business on the Regular
Record Date at such address as shall appear in the Security Register.

         (b) The amount of interest payable for any period will be computed on
the basis of a 360-day year of twelve 30-day months. Except as provided in the
following sentence, the amount of interest payable for any period shorter than a
full quarterly period for which interest is computed, will be computed 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 on the Debentures is not a Business Day,
then payment of interest payable on such date will be made on the next
succeeding day which 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 succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on the date that such interest otherwise would have been payable.

         (c) Maturity or redemption of a Debenture shall cause interest to cease
to accrue on such Debenture subject to the Company's obligation to pay interest
on overdue amounts in accordance with Section 503 of the Original Indenture and
the terms of this Supplemental Indenture and the Debentures.

                                       10
<PAGE>
         SECTION 205. Extension of Interest Payment Period.

         (a) So long as no Event of Default with respect to the Debentures has
occurred and is continuing, the Company shall have the right, at any time and
from time to time during the term of the Debentures, to defer payments of
interest by extending the interest payment period of such Debentures not
exceeding 20 consecutive quarters (the "Extension Period"), during which
Extension Period no interest shall be due and payable; provided that no
Extension Period may extend beyond the Stated Maturity. 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 205, will
bear interest thereon at the Coupon Rate compounded quarterly for each quarter
of the Extension Period ("Compound Interest"). At the end of the Extension
Period, the Company shall pay all interest accrued and unpaid on the Debentures,
including any Additional Interest and Compound Interest (together, "Deferred
Interest") that shall be payable to the Holders in whose names the Debentures
are registered in the Security Register on the record date for the first
Interest Payment Date after the end of the Extension Period. Before the
termination of any Extension Period, the Company may shorten or further extend
such period, provided that such period together with all such further extensions
thereof shall not exceed 20 consecutive quarters, or extend beyond the Stated
Maturity of the Debentures. Upon the termination of any Extension Period and
upon 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 may prepay at any time all or any portion of the interest accrued
during an Extension Period.

         (b)      (i) If the Property Trustee is the sole registered Holder at
                  the time the Company selects an Extension Period or any
                  shortening or extension thereof, the Company shall give
                  written notice to the Administrative Trustees, the Property
                  Trustee and the Trustee of its selection of such Extension
                  Period or any shortening or extension thereof one Business Day
                  before the earlier of (x) the next succeeding date on which
                  Distributions on the Trust Securities are payable, or (y) the
                  date the Trust is required to give notice of the record date,
                  or the date such Distributions are payable, to the NYSE or
                  other applicable self-regulatory organization where the Trust
                  Preferred Securities are then listed or to holders of the
                  Trust Preferred Securities, but in any event at least one
                  Business Day before such record date.

                  (ii) If the Property Trustee is not the sole Holder at the
                  time the Company selects an Extension Period, the Company
                  shall give the Holders of the Debentures and the Trustee
                  written notice of its selection of such Extension Period or
                  any shortening or extension thereof at least ten Business Days
                  before the earlier of (x) the next succeeding Interest Payment
                  Date, or (y) if the Debentures are then listed, the date the
                  Company is required to give notice of the record date or the
                  Interest Payment Date to the NYSE or other applicable
                  self-regulatory organization or to Holders of the Debentures.

<PAGE>
                  (iii) The quarter in which any notice is given pursuant to
                  subparagraphs (i) or (ii) of this paragraph (b) shall be
                  counted as one of the 20 quarters permitted in the maximum
                  Extension Period permitted under paragraph (a).

         (c) The Company shall cause the Trust to give written notice of the
selection, shortening or extension of any Extension Period to the holders of the
Trust Preferred Securities.

         SECTION 206. Form of Debentures. Attached hereto as Exhibit A is a form
of the definitive Debentures.

                                 ARTICLE THREE

                          REDEMPTION OF THE DEBENTURES

         SECTION 301. Optional Redemption.

         The Debentures are redeemable prior to the Stated Maturity at the
option of the Company (i) in whole or in part, from time to time, on or after
February 1, 2007 or (ii) at any time prior to February 1, 2007, in whole but not
in part, within 90 days following the occurrence of a Special Event, in either
case at a redemption price (the "Redemption Price") equal to 100% of the
principal amount thereof, plus accrued and unpaid interest thereon (including
Additional Interest and Compound Interest, if any) to the date of prepayment.

         The Company's right to redeem the Debentures under the preceding
paragraph shall be subject to the condition that if at the time there is
available to the Company or the Trust the opportunity to eliminate a Special
Event, within 90 days following the occurrence and continuation of such Special
Event, by taking some ministerial action ("Ministerial Action"), such as filing
a form or making an election, or pursuing some other similar reasonable measure
that will have no adverse effect on the Company, the Trust or the holders of the
Trust Securities issued by the Trust and will involve no material cost, the
Company shall pursue such measures in lieu of redemption; provided further, that
the Company shall have no right to redeem the Debentures while the Company or
the Trust is pursuing any Ministerial Action pursuant to the Agreement.

         SECTION 302. Redemption Procedures.

         Notice of any redemption will be mailed at least 30 days but not more
than 60 days before the Redemption Date to each Holder of Debentures to be
prepaid at its registered address. Unless the Company defaults in payment of the
Redemption Price, on and after the Redemption Date interest shall cease to
accrue on such Debentures called for redemption. If the Debentures are only
partially redeemed pursuant to Section 301, the Debentures will be redeemed pro
rata or by lot or by any other method utilized by the Trustee; provided, that if
at the time of redemption the Debentures are registered as a Global Debenture,
the Depositary shall determine, in accordance with its procedures, the principal
amount of such Debentures held by each

                                       12
<PAGE>
Depositary participant to be redeemed. The Redemption Price shall be paid prior
to 12:00 noon, New York time, on the date of such redemption or at such earlier
time as the Company determines; provided that the Company shall deposit with the
Trustee an amount sufficient to pay the Redemption Price by 10:00 a.m., New York
time, on the date such Redemption Price is to be paid.

         SECTION 303. No Sinking Fund.

         The Debentures are not entitled to the benefit of any sinking fund.

                                  ARTICLE FOUR

                                    EXPENSES

         SECTION 401. Payment of Expenses.

         In connection with the offering, sale and issuance of the Debentures
and in connection with the sale of the Trust Securities by the Trust, the
Company, in its capacity as borrower with respect to the Debentures, shall:

         (a) pay all costs and expenses relating to the offering, sale and
issuance of the Debentures, including commissions to the Underwriters payable
pursuant to the Underwriting Agreement and compensation of the Trustee under the
Indenture in accordance with the provisions of Section 606 of the Original
Indenture;

         (b) be responsible for and shall pay all debts and obligations (other
than with respect to the Trust Securities) and all costs and expenses of the
Trust (including, but not limited to, costs and expenses relating to the
organization, maintenance and dissolution of the Trust, the offering, sale and
issuance of the Trust Securities (including commissions to the Underwriters in
connection therewith), the fees and expenses (including reasonable counsel fees
and expenses) of the Property Trustee, the Delaware Trustee and the
Administrative Trustees (including any amounts payable under Article 10 of the
Agreement), the costs and expenses relating to the operation of the Trust,
including without limitation, costs and expenses of accountants, attorneys,
statistical or bookkeeping services, expenses for printing and engraving and
computing or accounting equipment, paying agent(s), registrar(s), transfer
agent(s), duplicating, travel and telephone and other telecommunications
expenses and costs and expenses incurred in connection with the acquisition,
financing, and disposition of Trust assets and the enforcement by the Property
Trustee of the rights of the holders of the Trust Preferred Securities);

         (c) be liable for any indemnification obligations arising with respect
to the Agreement; and

                                       13
<PAGE>
         (d) pay any and all taxes (other than United States withholding taxes
attributable to the Trust or its assets) and all liabilities, costs and expenses
with respect to such taxes of the Trust.

         The Company's obligations under this Section 401 shall be for the
benefit of, and shall be enforceable by, any Person to whom such debts,
obligations, costs, expenses and taxes are owed (a "Creditor") whether or not
such Creditor has received notice hereof. Any such Creditor may enforce the
Company's obligations under this Section 401 directly against the Company and
the Company irrevocably waives any right of remedy to require that any such
Creditor take any action against the Trust or any other Person before proceeding
against the Company. The Company agrees to execute such additional agreements as
may be necessary or desirable in order to give full effect to the provisions of
this Section 401.

         The provisions of this Section shall survive the termination of this
Supplemental Indenture.

         SECTION 402. Payment Upon Resignation or Removal.

         Upon termination of this Supplemental Indenture or the Indenture or the
removal or resignation of the Trustee, unless otherwise stated, the Company
shall pay to the Trustee all amounts accrued to the date of such termination,
removal or resignation that are payable pursuant to Section 606 of the Original
Indenture. Upon termination of the Agreement or the removal or resignation of
the Delaware Trustee or the Property Trustee, as the case may be, pursuant to
Section 5.6 of the Agreement, the Company shall pay to the Delaware Trustee or
the Property Trustee, as the case may be, all amounts accrued to the date of
such termination, removal or resignation.

                                  ARTICLE FIVE

                          COVENANT TO LIST ON EXCHANGE

         SECTION 501. Listing on an Exchange.

         If the Debentures are distributed to the holders of the Trust
Securities, and the Trust Preferred Securities are then listed, the Company will
use its best efforts to list such Debentures on the NYSE or on such other
exchange as the Trust Preferred Securities are then listed.

                                  ARTICLE SIX

                           SUBORDINATION OF DEBENTURES

         SECTION 601. Debentures Subordinate to Senior Indebtedness. The Company
for itself, its successors and assigns, covenants and agrees, and each Holder of
Debentures issued, whether upon original issue or upon transfer or assignment
thereof, by its acceptance thereof

                                       14
<PAGE>
likewise covenants and agrees, that the payment of principal of and interest on
each and all of the Debentures is hereby expressly subordinated, to the extent
and in the manner hereinafter in this Article set forth, in right of payment to
the prior payment in full of all existing and future Senior Indebtedness of the
Company.

         SECTION 602. Payments to Securityholders. (a) (i) In the event and
during the continuation of any default beyond any grace period in the payment of
principal of or interest on or any other monetary amounts due in respect of any
Senior Indebtedness, or in the event that any other event of default with
respect to any Senior Indebtedness shall have occurred and be continuing and
shall have resulted in such Senior Indebtedness becoming or being declared due
and payable prior to the date on which it would otherwise have become due and
payable and the Trustee has received written notice from the Company, from
holders of Senior Indebtedness or from any trustee, representative or agent
therefor, unless and until such event of default shall have been cured, waived
or remedied or shall have ceased to exist and such acceleration shall have been
rescinded or annulled or all amounts due on such Senior Indebtedness are paid in
full in cash or other permitted consideration, or otherwise provided for, then
no payment of the principal of or interest on the Debentures shall be made by
the Company.

         (ii) Upon any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities, to creditors upon
any dissolution or winding-up or total or partial liquidation or reorganization
of the Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all principal, premium, if any, and interest,
if any, due upon all Senior Indebtedness shall first be paid in full, or payment
thereof provided for in money or money's worth in accordance with its terms,
before any payment is made on account of the principal of or interest on the
indebtedness evidenced by the Debentures, and upon any such dissolution,
winding-up, liquidation or reorganization, any payment or distribution of assets
of the Company of any kind or character, whether in cash, property or
securities, to which the Holders of the Debentures under the terms of this
Supplemental Indenture would be entitled, except for the provisions hereof,
shall (subject to the power of a court of competent jurisdiction to make other
equitable provision reflecting the rights conferred by the provisions hereof
upon the Senior Indebtedness and the holders thereof with respect to the
Debentures and the Holders thereof by a lawful plan of reorganization under
applicable bankruptcy law), be paid by the Company or any receiver, trustee in
bankruptcy, liquidating trustee, agent or other person making such payment or
distribution, or by the Holders of the Debentures if received by them, directly
to the holders of Senior Indebtedness (pro rata to each such holder on the basis
of the respective amounts of Senior Indebtedness held by such holder) or their
representatives, to the extent necessary to pay all Senior Indebtedness
(including interest thereon) in full, in money or money's worth, in accordance
with its terms, after giving effect to any concurrent payment or distribution to
or for the holders of Senior Indebtedness, before any payment or distribution is
made to the holders of the indebtedness evidenced by the Debentures. The
consolidation of the Company with, or a merger of the Company into, another
Person or the liquidation or dissolution of the Company following the conveyance
or transfer of its property as an entirety, or substantially as an entirety, to
another Person upon the terms and conditions

                                       15
<PAGE>
provided in Section 801 of the Original Indenture shall not be deemed a
dissolution, winding-up, liquidation or reorganization for the purposes of this
Section 602(a).

         (b) In the event that any payment or distribution of assets of the
Company of any kind or character not permitted by Section 602(a), whether in
cash, property or securities, shall be received by the Trustee or the Holders of
Debentures before all Senior Indebtedness is paid in full, or provision made for
such payment, in accordance with its terms, upon written notice to the Trustee
or, as the case may be, such Holder, such payment or distribution shall be held
in trust for the benefit of, and shall be paid over or delivered to, the holders
of such Senior Indebtedness or their representative or representatives, or to
the Trustee or trustees under any indenture pursuant to which any instruments
evidencing any of such Senior Indebtedness may have been issued, as their
respective interests may appear, for application to the payment of all Senior
Indebtedness remaining unpaid to the extent necessary to pay all such Senior
Indebtedness in full in accordance with its terms, after giving effect to any
concurrent payment or distribution to the holders of such Senior Indebtedness.
Nothing in this Article shall apply to claims of, or payments to, the Trustee
under or pursuant to Section 606 of the Original Indenture. In addition, nothing
in this Article shall prevent the Company from making or the Trustee from
receiving or applying any payment in connection with the redemption of the
Debentures if the first publication of notice of such redemption (whether by
mail or otherwise in accordance with this Supplemental Indenture) has been made,
and the Trustee has received such payment from the Company, prior to the
occurrence of any of the contingencies specified in this Section 602.

         SECTION 603. Subrogation to Rights of Holders of Senior Indebtedness.
From and after the payment in full of all Senior Indebtedness, the Holders of
the Debentures (together with the holders of any other indebtedness of the
Company which is subordinate in right of payment to the payment in full of all
Senior Indebtedness, which is not subordinate in right of payment to the
Debentures and which by its terms grants such right of subrogation to the holder
thereof) shall be subrogated to the rights of the holders of Senior Indebtedness
to receive payments or distributions of assets or securities of the Company
applicable to the Senior Indebtedness until the Debentures shall be paid in
full, and, for the purposes of such subrogation, no such payments or
distributions to the holders of Senior Indebtedness of assets or securities,
which otherwise would have been payable or distributable to Holders of the
Debentures, shall, as between the Company, its creditors other than the holders
of Senior Indebtedness, and the Holders of the Debentures, be deemed to be a
payment by the Company to or on account of the Senior Indebtedness, it being
understood that the provisions of this Article are and are intended solely for
the purpose of defining the relative rights of the Holders of the Debentures, on
the one hand, and the holders of the Senior Indebtedness, on the other hand, and
nothing contained herein is intended to or shall impair as between the Company,
its creditors other than the holders of Senior Indebtedness, and the Holders of
the Debentures, the obligation of the Company, which is unconditional and
absolute, to pay to the Holders of the Debentures the principal of and interest
on the Debentures as and when the same shall become due and payable in
accordance with their terms, or to affect the relative rights of the Holders of
the Debentures and creditors of the Company other than the holders of the Senior
Indebtedness, nor shall anything herein or therein

                                       16
<PAGE>
prevent the Trustee or the Holder of Debentures from exercising all remedies
otherwise permitted by applicable law upon default hereunder with respect to the
Debentures subject to the rights of the holders of Senior Indebtedness, under
Section 602, to receive cash, property or securities of the Company otherwise
payable or deliverable to the Trustee or the Holders of the Debentures or to a
representative of such Holders, on their behalf.

         Upon any distribution or payment in connection with any proceedings or
sale referred to in Section 602(a), the Trustee and each Holder of the
Debentures then Outstanding, shall be entitled to rely upon a certificate of the
liquidating trustee or agent or other Person making any distribution or payment
to the Trustee or such Holder for the purpose of ascertaining the holders of
Senior Indebtedness entitled to participate in such payment or distribution, the
amount of such Senior Indebtedness or the amount payable thereon, the amount or
amounts paid or distributed thereon and all other facts pertinent thereto or to
this Article.

         SECTION 604. No Impairment of Subordination. Nothing contained in this
Article or elsewhere in this Supplemental Indenture or the Debentures shall
prevent at any time the Company from making payments at any time of principal of
or interest on the Debentures, except under the conditions described in Section
602 or during the pendency of any proceedings or sale therein referred to.

         SECTION 605. Trustee to Effectuate Subordination. Each Holder of
Debentures by his acceptance thereof, whether upon original issue or upon
transfer or assignment, authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate to effectuate the subordination
provisions in this Article and appoints the Trustee his attorney-in-fact for any
and all such purposes.

         No rights of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Trustee
or any Holder of the Debentures then Outstanding, or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by any such
holder, with the terms, provisions and covenants of this Supplemental Indenture,
regardless of any knowledge thereof which any such holder may have or otherwise
be charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness may, at any time and from time to time,
without the consent of or notice to the Holders of the Debentures, without
incurring responsibility to the Holders of the Debentures and without impairing
or releasing the subordination provided in this Article or the obligations of
the Holders of the Debentures to the holders of Senior Indebtedness, do any one
or more of the following: (i) change the manner, place or terms of payment of,
or renew or alter, Senior Indebtedness, or otherwise amend or supplement in any
manner Senior Indebtedness or any instrument evidencing the same or any
agreement under which Senior Indebtedness is outstanding; (ii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Indebtedness; (iii) release any Person liable in any manner for
the

                                       17
<PAGE>
collection of Senior Indebtedness; and (iv) exercise or refrain from exercising
any rights against the Company and any other Person.

         SECTION 606. Notice to Trustee. The Company shall give prompt written
notice to the Trustee in the form of an Officers' Certificate of any fact known
to the Company which would prohibit the making of any payment of money to or by
the Trustee in respect of the Debentures pursuant to the provisions of this
Article. Notwithstanding the provisions of this Article or any other provisions
of this Supplemental Indenture, the Trustee shall not be charged with knowledge
of the existence of any facts which would prohibit the making of any payment to
or by the Trustee in respect of the Debentures pursuant to the provisions of
this Article, unless and until the Trustee shall have received at its Corporate
Trust Office written notice thereof from the Company or a holder or holders of
Senior Indebtedness or from any trustee therefor at least two Business Days
prior to such payment date; and, prior to the receipt of any such written
notice, the Trustee, shall be entitled in all respects to assume that no such
facts exist.

         The Trustee shall be entitled to rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness (or a trustee on behalf of such holder) to establish that such
notice has been given by a holder of Senior Indebtedness or a trustee on behalf
of any such holder. In the event that the Trustee determines in good faith that
further evidence is required with respect to the right of any Person as a holder
of Senior Indebtedness to participate in any payment or distribution pursuant to
this Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article, and, if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

         SECTION 607. Reliance on Certificate of Liquidating Agent. Upon any
payment or distribution referred to in this Article, the Trustee and the Holders
of the Debentures shall be entitled to rely upon any order or decree entered by
any court of competent jurisdiction in which a dissolution, winding up or total
or partial liquidation or reorganization of the Company is pending, or a
certificate of the trustee in bankruptcy, liquidating trustee, custodian,
receiver, assignee for the benefit of creditors, agent or other Person making
such payment or distribution, delivered to the Trustee or to the Holders of the
Debentures, for the purpose of ascertaining the Persons entitled to participate
in such distribution, the holders of the Senior Indebtedness and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article.

         SECTION 608. Trustee Not Fiduciary for Holders of Senior Indebtedness.
The Trustee shall not be deemed to owe any fiduciary duty to the holders of
Senior Indebtedness and shall not be liable to any such holders if it shall in
good faith mistakenly pay over or distribute to Holders of the Debentures or to
the Company or to any other Person cash, property or securities to which any
holders of Senior Indebtedness shall be entitled by virtue of this Article or
otherwise.

                                       18
<PAGE>
         SECTION 609. Rights of Trustee as Holder of Senior Indebtedness. The
Trustee in its individual capacity shall be entitled to all the rights set forth
in this Article with respect to any Senior Indebtedness which may at any time be
held by it, to the same extent as any other holder of Senior Indebtedness, and
nothing in this Supplemental Indenture shall deprive the Trustee of any of its
rights as such holder.

         SECTION 610. Article Applicable to Paying Agent. In case at any time
any Paying Agent other than the Trustee shall have been appointed by the Company
and be then acting hereunder, the term "Trustee" as used in this Article shall
in such case (unless the context shall otherwise require) be construed as
extending to and including such Paying Agent within its meaning as fully for all
intents and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee; provided, however, that this Section
shall not apply to the Company or any Affiliate of the Company if it or such
Affiliate acts as Paying Agent.

                                 ARTICLE SEVEN

                            MISCELLANEOUS PROVISIONS

         The Trustee makes no undertaking or representations in respect of, and
shall not be responsible in any manner whatsoever for and in respect of, the
validity or sufficiency of this Supplemental Indenture or the proper
authorization or the due execution hereof by the Company or for or in respect of
the recitals and statements contained herein, all of which recitals and

                  7.8% JUNIOR SUBORDINATED DEBENTURES DUE 2032

DTE ENERGY COMPANY, a corporation duly organized and existing under the laws of
the State of Michigan (herein referred to as the "Company", which term includes
any successor Person under the Indenture hereinafter referred to), for value
received, hereby promises to pay to _________, or registered assigns, the
principal sum of $___________ on February 1, 2032 ("Stated Maturity"), unless
previously redeemed, and to pay interest at the rate of 7.8% per annum on said
principal sum from the date of issuance until the principal of this Debenture
becomes due and payable, and on any overdue principal 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 during such overdue period.
Interest on this Debenture will be payable quarterly in arrears on February 1,
May 1, August 1 and November 1 of each year (each such date, an "Interest
Payment Date"), commencing May 1, 2002.

                                      A-1
<PAGE>
The amount of interest payable for any period shall be computed on the basis of
twelve 30-day months and a 360-day year and, for any period shorter than a full
quarterly interest period, will be computed 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 on this Debenture is not a Business Day, then payment of the amount
payable on such date will be made on the next succeeding day which 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 succeeding calendar year, such
payment shall be made on the immediately preceding Business Day without
reduction in the amount due to such early payment, in each case with the same
force and effect as if made on such date. Payments of interest may be deferred
by the Company pursuant to the provisions of Article Two of the Supplemental
Indenture (as defined herein) to the Indenture (as defined herein). The interest
installment so payable, and punctually paid or duly provided for, on any

Indenture, be paid to the person in whose name this Debenture (or one or more
Predecessor Securities) is registered at the close of business on the relevant
Regular Record Date prior to the relevant Interest Payment Date. Any such
interest installment not punctually paid or duly provided for shall forthwith
cease to be payable to the registered Holders on such Regular Record Date, and

Predecessor Securities) is registered at the close of business on a Special

of Debentures not less than ten 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 Debentures may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in the Indenture. Except as otherwise provided in the Indenture, the
principal of and the interest on this Debenture shall be payable at the office
or agency of the Company maintained for that purpose in the Borough of

America which at the time of payment is legal tender for payment of public and
private debts; provided, however, that payment of interest may be made at the
option of the Company by check mailed to the registered Holder at the close of
business on the Regular Record Date at such address as shall appear in the
Security Register.

All references in this Debenture to interest shall include Additional Interest,
if any, and Compound Interest, if any.

designated as the "7.8% Junior Subordinated Debentures due 2032" (the
"Debentures"), limited to an aggregate principal amount of $185,567,025 (except
for Debentures authenticated and delivered upon transfer of, or in exchange for,
or in lieu of other Debentures), all issued under and pursuant to an Amended and
Restated Indenture, dated as of April 9, 2001, as supplemented by the Fourth
Supplemental Indenture dated as of January 15, 2002, with respect to the
Debentures (the "Supplemental Indenture"), as further amended, supplemented or

(herein referred to as the "Trustee", which term includes any successor trustee
under the Indenture), to which Indenture reference is hereby made for a
description of the respective rights, limitations of rights, obligations, duties
and immunities thereunder of the Trustee, the Company and the registered Holders
of the Debentures and of the terms upon which the Debentures are, and are to be,
authenticated and delivered.

Payment of the principal of and interest on this Debenture is, to the extent
provided in the Indenture, subordinated and subject in right of payment to the
prior payment in full of all existing and future Senior Indebtedness of the
Company and this Debenture is issued subject to the provisions of the Indenture
with respect thereto. Each registered Holder of this Debenture, by accepting the
same, (a) agrees to and shall be bound by such provisions, (b) authorizes and
directs the Trustee on his or her behalf to take such action as may be necessary
or appropriate to acknowledge or effectuate the subordination so provided and
(c) appoints the Trustee as his or her attorney-in-fact for any and all such
purposes. Each registered Holder hereof, by his or her acceptance hereof, hereby
waives all notice of the acceptance of the subordination provisions contained
herein and in the Indenture by each holder of Senior Indebtedness, whether now
outstanding or hereafter incurred, and waives reliance by each such Holder upon
said provisions.

The Company and, by its acceptance of this Debenture or a beneficial interest
herein, the registered Holder of, and any Person that acquires a beneficial
interest in, this Debenture agree that for United States federal, state and
local tax purposes it is intended that this Debenture constitute indebtedness.

Notwithstanding the provisions of the Indenture, this Debenture shall be without
benefit of any security and shall be subordinated to Senior Indebtedness.

This Debenture is not subject to repayment at the option of the Holder hereof.
Except as provided below, this Debenture is not redeemable by the Company prior
to maturity and is not subject to any sinking fund.

This Debenture shall be redeemable prior to its Stated Maturity at the option of
the Company (i) in whole or in part, from time to time, on or after February 1,
2007 or (ii) at any time prior to February 1, 2007, in whole but not in part,
within 90 days following the occurrence of a Special Event, in either case at a
redemption price (the "Redemption Price") equal to 100% of the principal amount
thereof, plus accrued and unpaid interest thereon (including Additional Interest
and Compound Interest, if any) to the date of redemption.

Notice of any redemption will be mailed at least 30 days but not more than 60
days before the redemption date to the Holder hereof at its registered address.
Unless the Company defaults in payment of the Redemption Price, on and after the
redemption date interest will cease to accrue on the principal amount of this
Debenture called for redemption.

If money sufficient to pay the Redemption Price with respect to the principal
amount of and accrued interest on the principal amount of this Debenture to be
redeemed on the redemption

                                      A-3
<PAGE>
date is deposited with the Trustee or Paying Agent on or before the redemption
date and certain other conditions are satisfied, then on or after such date,
interest will cease to accrue on the principal amount of this Debenture called
for redemption.

If the Debentures are only partially redeemed by the Company, the Debentures
will be redeemed pro rata or by lot or by any other method utilized by the
Trustee; provided that if, at the time of redemption, the Debentures are
registered as a Global Debenture, the Depositary shall determine by lot the
principal amount of such Debentures held by each Debenture Holder to be
redeemed.

In the event of redemption of this Debenture in part only, a new Debenture or
Debentures of this series for the unredeemed portion hereof will be issued in
the name of the registered Holder hereof upon the cancellation hereof.

In case an Event of Default, as defined in the Indenture, shall have occurred
and be continuing, the principal hereof may be declared, and upon such
declaration shall become, due and payable, in the manner, with the effect and
subject to the conditions provided in the Indenture.

The provisions relating to defeasance and covenant defeasance in the Indenture
in Section 403 thereof shall not apply to this Debenture.

The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Debentures under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority of the aggregate principal amount of all Debentures issued under the
Indenture at the time outstanding and affected thereby; provided, however, that
no such amendment shall without the consent of the Holder of each Debenture so
affected, among other things (i) change the stated maturity of the principal of,
or any installment of principal of or interest on any Debentures of any series,
or reduce the principal amount thereof, or reduce the rate of interest thereon,
or reduce any premium payable upon the redemption thereof, (ii) reduce the
aforesaid percentage of the Holders of which are required to consent to any such
supplemental indenture or (iii) modify any of the subordination provisions
contained herein in a manner adverse to the Holder hereof. The Indenture also
contains provisions permitting (i) the registered Holders of at least 66 2/3% in
aggregate principal amount of the Securities of all series at the time
outstanding affected thereby, on behalf of the registered Holders of the
Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and (ii) the registered Holders of not less than a
majority in aggregate principal amount of the Securities of any series at the
time outstanding affected thereby, on behalf of the registered Holders of the
Securities of such series, to waive certain past defaults under the Indenture
and their consequences. Any such consent or waiver by the registered Holder of
this Debenture (unless revoked as provided in the Indenture) shall be conclusive
and binding upon such registered Holder and upon all future registered Holders
and owners of this Debenture and of any Debenture issued in exchange hereof or
in place hereof (whether by registration of transfer or otherwise), irrespective
of whether or not any notation of such consent or waiver is made upon this
Debenture.

the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this
Debenture at the time and place and at the 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 this Debenture is registrable in the Security Register of
the Company, upon surrender of this Debenture for registration of transfer at
the office or agency of the Company in any place where the principal of and any
interest on this Debenture are payable or at such other offices or agencies as
the Company may designate, duly endorsed by or accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company and
the Security Registrar or any transfer agent duly executed by the registered
Holder hereof or his or her attorney duly authorized in writing, and thereupon
one or more new Debentures of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount will be issued to the
designated transferee or transferees. No service charge will be made for any
such transfer, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in relation thereto.

Prior to due presentment for registration of transfer of this Debenture, the
Company, the Trustee, any Paying Agent and any Security Registrar may deem and
treat the registered Holder hereof as the absolute owner hereof (whether or not
this Debenture shall be overdue and notwithstanding any notice of ownership or
writing hereon made by anyone other than the Security Registrar) for the purpose
of receiving payment of or on account of the principal hereof and interest due
hereon and for all other purposes, and neither the Company nor the Trustee nor
any paying agent nor any Security Registrar shall be affected by any notice to
the contrary.

The Debentures of this series are issuable only in fully registered form without
coupons in denominations of $25 and any integral multiple thereof. This Global
Debenture is exchangeable for Debentures in definitive form only under certain
limited circumstances set forth in the Indenture. Debentures of this series so
issued are issuable only in registered form without coupons in denominations of
$25 and any integral multiple thereof. As provided in the Indenture and subject
to certain limitations therein set forth, Debentures of this series are
exchangeable for a like aggregate principal amount of Debentures of this series
of a different authorized denomination, as requested by the registered Holder
surrendering the same.

As set forth in, and subject to the provisions of, the Indenture, no registered
owner of any Debenture will have any right to institute any proceeding with
respect to the Indenture or for any remedy thereunder, unless (i) such
registered owner shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to the Debentures of this series, (ii)
the registered owners of not less than 25% in principal amount of the
Outstanding Debentures of this series shall have made written request, and
offered reasonable indemnity, to the Trustee to institute such proceeding as
trustee, (iii) the Trustee shall have failed to institute such proceeding within
60 days and (iv) the Trustee shall not have received from the registered owners
of a majority in principal amount of the outstanding Debentures of this series a
direction inconsistent

                                      A-5

with such request within such 60-day period; provided, however, that such
limitations do not apply to a suit instituted by the registered owner hereof for
the enforcement of payment of the principal of or any interest on this Debenture
on or after the respective due dates expressed herein.

Unless the Certificate of Authentication hereon has been executed by the Trustee
or a duly appointed Authentication Agent referred to herein, this Debenture
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

The Indenture and this Debenture shall be governed and construed in accordance
with the laws of the State of New York.

All terms used in this Debenture which are defined in the Indenture shall have
the meanings assigned to them in the Indenture.
