Michigan corporation (the "Guarantor"), and The Bank of New York, as trustee
(the "Preferred Securities Guarantee Trustee"), for the benefit of the Holders
(as defined herein) from time to time of the Preferred Securities (as defined
herein) of DTE Energy Trust I, a Delaware statutory business trust (the
"Issuer").

         WHEREAS, pursuant to an Amended and Restated Trust Agreement (the

named therein, the Guarantor, as sponsor, and the holders from time to time of
undivided beneficial interests in the assets of the Issuer, the Issuer is
issuing on the date hereof 7,200,000 preferred securities, liquidation amount
$25 per preferred security, having an aggregate liquidation amount of
$180,000,000, designated the 7.8% Trust Preferred Securities (the "Preferred
Securities");

         WHEREAS, as incentive for the Holders to purchase the Preferred
Securities, the Guarantor desires irrevocably and unconditionally to agree, to
the extent set forth in this Preferred Securities Guarantee, to pay to the
Holders the Guarantee Payments (as defined herein) and to make certain other
payments and fulfill certain other obligations on the terms and conditions set
forth herein; and

benefit of the holders of the Common Securities (as defined herein), except that
if an Event of Default (as defined in the Agreement), has occurred and is
continuing, the rights of holders of the Common Securities to receive Guarantee
Payments under the Common Securities Guarantee are subordinated to the rights of

         NOW, THEREFORE, in consideration of the purchase by each Holder, which
purchase the Guarantor hereby agrees shall benefit the Guarantor, the Guarantor
executes and delivers this Guarantee for the benefit of the Holders.

         (b) If an Event of Default actually known to a Responsible Officer of

Preferred Securities Guarantee Trustee shall enforce this Preferred Securities
Guarantee for the benefit of the Holders.

         (c) The Preferred Securities Guarantee Trustee, before the occurrence
of any Event of Default and after the curing or waiver of all Events of Default
that may have occurred, shall undertake to perform only such duties as are
specifically set forth in this Preferred Securities

Guarantee, and no implied covenants or obligations shall be read into this
Preferred Securities Guarantee against the Preferred Securities Guarantee
Trustee. In case an Event of Default has occurred (that has not been cured or
waived pursuant to Section 2.6) and is actually known to a Responsible Officer
of the Preferred Securities Guarantee Trustee, the Preferred Securities
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Preferred Securities Guarantee, and use the same degree of care and skill
in its exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

         (d) No provision of this Preferred Securities Guarantee shall be
construed to relieve the Preferred Securities Guarantee Trustee from liability
for its own negligent action, its own negligent failure to act, its own bad
faith or its own willful misconduct, except that:

                  (i) prior to the occurrence of any Event of Default and after
         the curing or waiving of such Events of Default that may have occurred:

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

                       (2) in the absence of bad faith on the part of the
                  Preferred Securities Guarantee Trustee, the Preferred
                  Securities Guarantee 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 Preferred Securities Guarantee Trustee and conforming
                  to the requirements of this Preferred Securities Guarantee;
                  but in the case of any such certificates or opinions that by
                  any provision hereof are specifically required to be furnished
                  to the Preferred Securities Guarantee Trustee, the Preferred
                  Securities Guarantee Trustee shall be under a duty to examine
                  the same to determine whether or not they conform to the
                  requirements of this Preferred Securities Guarantee;

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

                  (iii) the Preferred Securities Guarantee Trustee shall not be
         liable with respect to any action taken or omitted to be taken by it in
         good faith in accordance with the direction of the Holders of not less
         than a Majority in liquidation amount of the Preferred Securities
         relating to the time, method and place of conducting any proceeding for
         any remedy available to the Preferred Securities Guarantee Trustee, or
         exercising any trust or power conferred upon the Preferred Securities
         Guarantee Trustee under this Preferred Securities Guarantee; and

                                       8


                  (iv) no provision of this Preferred Securities Guarantee shall
         require the Preferred Securities Guarantee 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 the Preferred Securities Guarantee Trustee shall
         have reasonable grounds for believing that the repayment of such funds
         or liability is not reasonably assured to it under the terms of this
         Preferred Securities Guarantee or if indemnity reasonably satisfactory
         to the Preferred Securities Guarantee Trustee against such risk or
         liability is not reasonably assured to it.

the Holders the Guarantee Payments (without duplication of amounts theretofore
paid by the Issuer), as and when due, regardless of any defense, right of
set-off or counterclaim that the Issuer may have or assert. The Guarantor's
obligation to make a Guarantee Payment may be satisfied by direct payment of the
required amounts by the Guarantor to the Holders or by causing the Issuer to pay
such amounts to the Holders.

         In addition, the Guarantor irrevocably and unconditionally agrees to
cause the Issuer to deliver to the Holders such securities and other property as
may be deliverable to them in accordance with the terms of the Preferred
Securities, including as a result of any exchange, redemption, liquidation or
other provision of the Debentures or the Preferred Securities.

SECTION 5.2 Waiver of Notice and Demand

         The Guarantor hereby waives notice of acceptance of this Preferred
Securities Guarantee and of any liability to which it applies or may apply,

notice of nonpayment, notice of dishonor, notice of redemption and all other
notices and demands.

SECTION 5.3 Obligations Not Affected

         The obligations, covenants, agreements and duties of the Guarantor
under this Preferred Securities Guarantee shall in no way be affected or
impaired by reason of the happening from time to time of any of the following:

         (a) the release or waiver, by operation of law or otherwise, of the
performance or observance by the Issuer of any express or implied agreement,
covenant, term or condition relating to the Preferred Securities to be performed
or observed by the Issuer;

         (b) the extension of time for the payment by the Issuer of all or any
portion any sums payable or the performance by the Issuer of any other
obligation under, arising out of, or in connection with, the Preferred
Securities (other than an extension of time permitted by the Indenture);

         (c) any failure, omission, delay or lack of diligence on the part of
the Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the Preferred Securities, or
any action on the part of the Issuer granting indulgence or extension of any
kind;

         (d) the voluntary or involuntary liquidation, dissolution, sale of any
collateral, receivership, insolvency, bankruptcy, assignment for the benefit of
creditors, reorganization,



                                       13

proceedings affecting, the Issuer or any of the assets of the Issuer;

         (e) any invalidity of, or defect or deficiency in, the Preferred
Securities;

         (f) the settlement or compromise of any obligation guaranteed hereby or
hereby incurred; or

         (g) any other circumstance whatsoever that might otherwise constitute a
legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.3 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances.

         There shall be no obligation of the Holders to give notice to, or
obtain the consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4 Rights of Holders

         (a) The Holders of a Majority in liquidation amount of the Preferred
Securities have the right to direct the time, method and place of conducting of
any proceeding for any remedy available to the Preferred Securities Guarantee
Trustee in respect of this Preferred Securities Guarantee or exercising any
trust or power conferred upon the Preferred Securities Guarantee Trustee under
this Preferred Securities Guarantee.

         (b) If the Preferred Securities Guarantee Trustee fails to enforce this
Preferred Securities Guarantee, any Holder may institute a legal proceeding
directly against the Guarantor to enforce its rights under this Preferred
Securities Guarantee, without first instituting a legal proceeding against the
Issuer, the Preferred Securities Guarantee Trustee or any other Person.
Notwithstanding the foregoing, if the Guarantor has failed to make a Guarantee
Payment or to perform any of its other obligations under Section 5.1, a Holder
may directly institute a proceeding in the Holder's own name against the
Guarantor for enforcement of this Preferred Securities Guarantee for the portion
of such Guarantee Payment or the performance of such other obligation to which
such Holder is entitled. The Guarantor waives any right or remedy to require
that any action on this Preferred Securities Guarantee be brought first against
the Issuer or any other person or entity before proceeding directly against the
Guarantor.

SECTION 5.5 Guarantee of Payment

         This Preferred Securities Guarantee creates a guarantee of payment and
not of collection. This Preferred Securities Guarantee will not be discharged
except by payment of the Guarantee Payments in full (without duplication of
amounts theretofore paid by the Issuer) or upon distribution of Debentures to
Holders as provided in the Agreement.

SECTION 5.6 Subrogation

         The Guarantor shall be subrogated to all rights, if any, of the Holders
against the Issuer in respect of any amounts paid to such Holders by the
Guarantor under this Preferred Securities Guarantee; provided, however, that the
Guarantor shall not (except to the extent required by



                                       14


mandatory provisions of law) be entitled to enforce or exercise any right that
it may acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Preferred Securities
Guarantee, if, at the time of any such payment, any amounts are due and unpaid
under this Preferred Securities Guarantee. If any amount shall be paid or
property delivered to the Guarantor in violation of the preceding sentence, the
Guarantor agrees to hold such amount or property in trust for the Holders and to
pay over such amount or deliver such property to the Holders entitled thereto.

SECTION 5.7 Independent Obligations

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Preferred
Securities, and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Preferred
Securities Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 5.3 hereof.

               Guarantor of the indebtedness of any Subsidiary thereof or any

               the Guarantor's dividend reinvestment plans);

if at such time (i) there shall have occurred and be continuing an Event of
Default under the Agreement or any event of which the Guarantor 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 Agreement, (ii) the Guarantor shall be in
default with respect to its payment or other obligations under Section 5.1 of
this Preferred Securities Guarantee or (iii) the Guarantor shall have given
notice of its election to begin an Extension Period as provided in the Indenture
and shall not have rescinded such notice or such Extension Period, or any
extension thereof, shall have commenced and be continuing.

         In addition, so long as any Preferred Securities remain outstanding,
the Guarantor (i) will remain the sole direct or indirect owner of all of the
outstanding Preferred Securities of the Issuer; provided that any permitted
successor or assignee of the Guarantor under the Indenture may succeed to the
Guarantor's ownership of the Preferred Securities and (ii) will not take any
action which would cause the Issuer to cease to be treated as a grantor trust
for United States federal income tax purposes except in connection with a
distribution of Debentures as provided in the Agreement.

SECTION 6.2  Ranking

         This Preferred Securities Guarantee will constitute an unsecured
obligation of the Guarantor and will rank subordinate and junior in right of
payment to all Senior Indebtedness of the Guarantor to the extent and in the
manner set forth in the supplemental indenture to the Indenture with respect to
the Debentures, and the subordination provisions of the supplemental indenture
to the Indenture with respect to the Debentures will apply, mutatis mutandis, to
the obligations of the Guarantor hereunder. The obligations of the Guarantor
hereunder do not constitute Senior Indebtedness of the Guarantor. The
obligations of the Guarantor under this Preferred Securities Guarantee shall
rank pari passu (or equally) with any similar guarantee agreements issued by the
Guarantor on behalf of the holders of preferred or capital securities issued by
the Issuer or Affiliates of the Guarantor similar to the Issuer and with any
other security, guarantee or other obligation that is expressly stated to rank
pari passu (or equally) with the obligations of the Guarantor under this
Preferred Securities Guarantee.

                                   TERMINATION

SECTION 7.1 Termination

         This Preferred Securities Guarantee shall terminate and be of no
further force and effect upon (i) full payment of the Redemption or Repayment
Price of all Preferred Securities, (ii) the exchange of all the Preferred
Securities and the full payment of any related amounts or (iii) full payment of
the amounts payable or delivery of securities or other property deliverable upon
liquidation of the Issuer, in each case, in accordance with the terms of the
Agreement. Notwithstanding the foregoing, this Preferred Securities Guarantee
will continue to be effective

or will be reinstated, as the case may be, if at any time any Holder must
restore payment of any sums paid or other property distributed under the
Preferred Securities or under this Preferred Securities Guarantee.

misconduct with respect to such acts or omissions.

         (b) An Indemnified Person shall be fully protected in relying in good
faith upon the records of the Guarantor and upon such information, opinions,
reports or statements presented to the Guarantor by any Person as to matters the
Indemnified Person reasonably believes are within such other Person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Guarantor, including information, opinions, reports or

SECTION 8.2 Indemnification

         (a) To the fullest extent permitted by applicable law, the Guarantor
agrees to 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 in
accordance with this Preferred Securities Guarantee and in a manner such
Indemnified Person reasonably believed to be within the scope of authority
conferred on such Indemnified Person by this Preferred Securities Guarantee,
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
negligence, bad faith or willful misconduct with respect to such acts or
omissions.

         (b) To the fullest extent permitted by applicable law, reasonable
out-of-pocket expenses (including reasonable legal fees) incurred by an

disposition of such claim, demand, action, suit or proceeding upon receipt by
the Guarantor of an undertaking by or on behalf of the Indemnified Person to
repay such amount if it shall be determined that the Indemnified Person is not
entitled to be indemnified as authorized in Section 8.2(a).

         (a) to pay to the Preferred Securities Guarantee Trustee from time to

the Preferred Securities Guarantee Trustee for all services rendered by it
hereunder (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust); and

         (b) to reimburse the Preferred Securities Guarantee Trustee upon its
request for reasonable expenses, disbursements and advances incurred or made by
the Preferred Securities Guarantee Trustee in accordance with any provision of
this Preferred Securities Guarantee (including the reasonable compensation and
the expenses and advances of its agents and counsel), except any such expense or
advance as may be attributable to its negligence, willful misconduct or bad
faith.
