                    NOTES TO CONDENSED CONSOLIDATED FINANCIAL
                             STATEMENTS (UNAUDITED)
                DTE ENERGY COMPANY AND THE DETROIT EDISON COMPANY

NOTE 1 - ANNUAL REPORT NOTES

These condensed consolidated financial statements (unaudited) should be read in
conjunction with the Annual Report Notes. The Notes contained herein update and
supplement matters discussed in the Annual Report Notes.

The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

The condensed consolidated financial statements are unaudited, but in the
opinion of the Company and Detroit Edison, with respect to its own financial
statements, include all adjustments necessary for a fair statement of the
results for the interim periods. Financial results for this interim period are
not necessarily indicative of results that may be expected for any other interim
period or for the fiscal year.

NOTE 2 - REGULATORY MATTERS

On March 8, 1999 the MPSC issued orders clarifying several issues related to
Direct Access. Among other things, the MPSC ruled that:

- -    Detroit Edison must reduce rates effective January 1, 2000 by $14.8 million
     to reflect the expiration of the 2-year extraordinary storm damage
     surcharge.
- -    Detroit Edison will be required to use its "best efforts" to provide
     standby service to Direct Access customers. Best efforts means that Detroit
     Edison must make the service available to Direct Access customers who
     request it, but Detroit Edison does not have to build or purchase new
     capacity or interrupt firm customers to provide the service.
- -    Standby service is to be priced at Detroit Edison's top incremental cost
     plus 1 cent. The service must be contracted for and scheduled in advance.
     There are no reservation charges or monthly fees.
- -    Detroit Edison should move expeditiously on the 90 MW of Direct Access
     pilot program, but the larger 675 MW block of Direct Access power should
     not become effective until the third quarter of 1999.
- -    DTE Energy affiliates may not participate in Direct Access until Detroit
     Edison files a code of conduct with the MPSC. On April 12, 1999, Detroit
     Edison filed a code of conduct with the MPSC.

Several parties have filed petitions for rehearing or clarification of some of
the March 8, 1999 orders; the MPSC has not ruled on these petitions. ABATE and
the Michigan Attorney General have also filed for leave to appeal the MPSC's
decision authorizing accelerated

                                       16

amortization of Detroit Edison's Fermi 2 assets, to the Michigan Court of
Appeals. Detroit Edison is unable to determine the timing or outcome of these
proceedings.

NOTE 3 - SHORT-TERM CREDIT ARRANGEMENTS AND BORROWINGS

At March 31, 1999, Detroit Edison had total short-term credit arrangements of
approximately $690 million under which $280 million of commercial paper was
outstanding.

At March 31, 1999, DTE Capital had short-term credit arrangements of $400
million, backed by a Support Agreement from the Company, under which no amounts
were outstanding.

In February 1999, the Company entered into a $40 million Support Agreement with
DTE Capital for the purpose of DTE Capital's credit enhancing activities on
behalf of DTE Energy affiliates.

NOTE 4 - SEGMENT AND RELATED INFORMATION

Effective December 31, 1998, the Company adopted Statement of Financial
Accounting Standards No. 131, "Disclosure about Segments of an Enterprise and
Related Information." The Company's reportable business segment is its electric
utility, Detroit Edison, which is engaged in the generation, purchase,
transmission, distribution and sale of electric energy in a 7,600 square mile
area in Southeastern Michigan. All other includes non-regulated energy-related
businesses and services, which develop and manage electricity and other
energy-related projects, and engage in domestic energy trading and marketing.
Inter-segment revenues are not material. Financial data for business segments
are as follows:

Edison, Circuit Court for Wayne County, Michigan; and Frazier v. Detroit Edison,
United States District Court, Eastern District of Michigan), are preparing for
binding arbitration to settle these matters. A July 1998 Consent Judgement has
received preliminary Court approval. A Fairness Hearing with respect to the
terms of the settlement was held in August 1998, and no objections to the
settlement were raised. A second Fairness Hearing is contemplated following the
results of the arbitration. The settlement agreement provides that Detroit
Edison's monetary liability is to be no less than $17.5 million and no greater
than $65 million after the conclusion of all related proceedings. Detroit Edison
has accrued an amount considered to be probable.

INDEPENDENT ACCOUNTANTS' REPORT

To the Board of Directors and Shareholders of DTE Energy Company and
       The Detroit Edison Company

We have reviewed the accompanying condensed consolidated balance sheets of DTE
Energy Company and subsidiaries and of The Detroit Edison Company and
subsidiaries as of March 31, 1999, and the related condensed consolidated
statements of income and cash flows for the three-month periods ended March 31,
1999 and 1998, and the condensed consolidated statements of changes in
shareholders' equity for the three-month period ended March 31, 1999. These
financial statements are the responsibility of DTE Energy Company's management
and of The Detroit Edison Company's management.

We conducted our reviews in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical procedures to
financial data and of making inquiries of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit conducted in
accordance with generally accepted auditing standards, the objective of which is
the expression of an opinion regarding the financial statements taken as a
whole. Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any material modifications that should
be made to such condensed consolidated financial statements for them to be in
conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheets of DTE Energy Company and
subsidiaries and of The Detroit Edison Company and subsidiaries as of December
31, 1998, and the related consolidated statements of income, changes in
shareholders' equity, and cash flows for the year then ended (not presented
herein); and in our report dated January 27, 1999, we expressed an unqualified
opinion on those consolidated financial statements. In our opinion, the
information set forth in the accompanying condensed consolidated balance sheets
as of December 31, 1998 is fairly stated, in all material respects, in relation
to the consolidated balance sheets from which it has been derived.

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS.

This analysis for the three months ended March 31, 1999, as compared to the same
period in 1998, should be read in conjunction with the condensed consolidated
financial statements (unaudited), the accompanying Notes, and the Annual Report
Notes.

Detroit Edison is the principal operating subsidiary of the Company and, as
such, unless otherwise identified, this discussion explains material changes in
results of operations of both the Company and Detroit Edison and identifies
recent trends and events affecting both the Company and Detroit Edison.

from the MPSC, and 2) to establish guidelines for transactions between
affiliates. The MPSC also set for hearing the ABATE complaint that had been
filed in August 1997 alleging that Detroit Edison's earnings are excessive. A
procedural schedule was set whereby an order could be issued in the first
quarter of 2000.

On March 31, 1999, Detroit Edison filed an application with the MPSC for true-up
of its stranded costs, including Direct Access implementation costs. Detroit
Edison requested that the proceedings be conducted in two phases. The first
phase should involve only a prudency review of incurred implementation costs,
approval of forecasted spending and allocation of implementation costs among
customers and the timing of cost recovery. The second phase should be structured
to address the remaining true-up issues; including the appropriate stranded cost
balances, the appropriate level of the transition charge, the establishment of
the mechanics of the true-up and stranded cost recovery processes, and to
address policy issues such as Detroit Edison's billing and metering rights and
obligations in a restructured electric utility industry. Expedited proceedings
were requested for both phases, and a procedural schedule will be determined in
May 1999.

FEDERAL ENERGY REGULATORY COMMISSION

On February 15, 1999, Detroit Edison submitted a request to the FERC for
authorization to use certain plant accounts to recognize the impairment loss of
Detroit Edison's Fermi 2 plant and associated assets in accordance with
generally accepted accounting principles. On March 26, 1999, the Michigan
Attorney General filed a protest with the FERC and requested that the FERC set
the issue for hearing. On April 12, 1999, Detroit Edison filed its response with
the FERC, requesting that the FERC reject the Michigan Attorney General's
protest as an improper collateral attack on MPSC orders. The FERC has not made a
ruling on these matters.

LIQUIDITY AND CAPITAL RESOURCES

CASH FROM OPERATING ACTIVITIES

Net cash from operating activities decreased in 1999 due primarily to decreases
in accounts payable and changes in other current assets and liabilities.

CASH USED FOR INVESTING ACTIVITIES

Net cash used for investing was lower due primarily to decreased non-regulated
investments and contributions to the nuclear decommissioning trust funds.

CASH (USED FOR) FROM FINANCING ACTIVITIES

Net cash used for financing was $63 million for the three months ended March 31,
1999 compared to net cash from financing of $133 million for the same period
during 1998. This fluctuation was primarily due to decreased DTE Capital
short-term borrowings, partially offset by redemptions of long-term debt.

YEAR 2000

The Company and Detroit Edison have been involved in an enterprise-wide program
to address Year 2000 issues. A program office was established in mid-1997 to
implement a rigorous plan to address the impact of Year 2000 on hardware and
software systems, embedded systems (which include microprocessors used in the
production and control of electric power), and critical service providers. The
emphasis has been on mission critical systems that support core business
activities or processes. Core business activities/processes include safety,
environmental and regulatory compliance, product production and delivery,
revenue collection, employee and supplier payment and financial asset
management.

The plan for addressing Year 2000 is divided into several phases including
raising general awareness of Year 2000 throughout the Company and Detroit
Edison; maintaining an inventory of systems and devices; performing an
assessment of inventoried systems and devices; performing compliance testing of
suspect systems and devices; remediation of non-compliant systems and devices
through replacement, repair, retirement, or identifying an acceptable work
around; testing and remediation of systems and devices in an integrated
environment and preparing business continuity plans.

Inventory, assessment and compliance testing phases have been completed for
known systems and devices. The remediation phase is approximately 91% complete
and is expected to be fully complete by August 1999 for mission critical assets
and supporting assets. Integration planning, including the mapping of critical
business processes, is near completion for Detroit Edison. Integration testing
and contingency planning is approximately 18% complete and is expected to be
fully complete by October 1999.

To support the program phases, the program office has been working with major
utility industry associations and organizations, customers and vendors to gather
and share 

                                       21
<PAGE>   22

information on Year 2000 issues. The program office has contacted vendors
critical to Company operations to determine their progress on Year 2000.

To further assist in identifying potential problems, tests of generating
facilities have been conducted by advancing control systems dates to the Year
2000. Results of these tests have shown that the generating facilities operated
successfully in this induced "millennium mode." Exercises were conducted on
December 31, 1998 and January 1, 1999 to assess the ability to reach employees
and the regional security centers of the East Central Area Reliability Group
through various communication channels. The exercised communication channels
operated properly. The business continuity program will provide opportunities to
conduct similar exercises on other systems in advance of the Year 2000. Similar
analysis has not been completed for other affiliates.

In the event that an unknown Year 2000 condition adversely affects service to
customers or an internal business process, contingency and business continuity
plans and procedures are being developed to provide rapid restoration to normal
conditions. The Company and Detroit Edison have always maintained a
comprehensive operational emergency response plan. The business continuity
function of the Year 2000 program will supplement the existing emergency plan to
include Year 2000 specific events. A Year 2000 emergency response office will be
fully operational by November 1999 to manage and coordinate operations,
including mobilization of all employees as necessary, during the transition to
the new millennium.

The Company and Detroit Edison believe that with all Year 2000 modifications,
business continuity and emergency management plans in place, the Year 2000 will
not have a material effect on their financial position, liquidity and results of
operations. Despite all efforts, there can be no assurances that Year 2000
issues can be totally eliminated. Results of modifications and testing done
during the fourth quarter of 1998 have demonstrated that Detroit Edison should
be able to maintain normal operating conditions into the Year 2000, although
there may be isolated electric service interruptions. Detroit Edison's internal
business systems may be affected by a Year 2000 related failure that could
temporarily interrupt the ability to communicate with customers, collect
revenue, or complete cash transactions. In addition, no assurances can be given
that the systems of vendors, interconnected utilities and customers will not
result in Year 2000 problems.

The Company estimates that Year 2000 costs will approximate $80 million
with $57 million expended through March 31, 1999. Operating cash flow is
expected to be sufficient to pay Year 2000 modification costs with no material
impact on operating results or cash flows.

RESULTS OF OPERATIONS

For the three months ended March 31, 1999, the Company's net income was $115
million, or $0.79 per common share as compared to $104 million, or $0.72 per
common share earned in the three months ended March 31, 1998.

                                       22
<PAGE>   23
The 1999 three-month earnings were higher than 1998 due to increased earnings
resulting from increased utilization of tax credits generated by non-regulated
businesses and increased electric system sales due to higher demand resulting
from colder weather.

OPERATING REVENUES

Increases in operating revenues were due primarily to higher non-regulated
subsidiary revenues, higher system and interconnection sales due to increased
heating load and usage, partially offset by decreases in total system revenues
driven mainly by lower rates.

Detroit Edison kWh sales increased (decreased) as compared to the prior year as
follows:

                                                                    Three
                                                                    Months
                                                                    ------
       Residential                                                     5.2  %
       Commercial                                                      3.8
       Industrial                                                      0.4
       Other (includes primarily sales for resale)                    11.2
           Total System                                                3.6
       Sales between utilities                                       (21.5)
           Total                                                       0.9

The increase in residential sales resulted from more heating related demand and
growth in the customer base. Commercial sales increased for the three-month
period, reflecting more heating related demand and a continuation
of favorable economic conditions. Sales to other customers increased reflecting
increased demand from sales for resale customers. Sales between utilities
decreased due to less power available for sale.

OPERATING EXPENSES

FUEL AND PURCHASED POWER

Net system output and average fuel and purchased power unit costs were as
follows:

                                                         Three Months

                                       23
<PAGE>   24

Fuel and purchased power expense increased for the Company due primarily to new
non-regulated subsidiary expenses. Detroit Edison fuel and purchased power
expense decreased due to an 18.3% reduction in steam heating sales and lower
average unit costs resulting from a decrease in the cost of nuclear fuel,
partially offset by higher net system output and increased purchases of higher
cost power to replace lower cost system generation as a result of plant outages.

OPERATION AND MAINTENANCE

Operation and maintenance expense for the Company increased due primarily to new
non-regulated subsidiary operation expense ($44 million), higher expenses
related to the timing of the periodic plant outages ($8.3 million), higher
expenses for Year 2000 testing and remediation ($7.9 million), higher expenses
for information systems ($2.4 million), partially offset by lower nuclear
generation expenses ($5.9 million).

INCOME TAXES

Income tax expense for the Company decreased in 1999 due primarily to increased
utilization of alternate fuels credits generated from non-regulated businesses.
Alternate fuels credits phase out beginning in 2003 through 2007.

FORWARD-LOOKING STATEMENTS

Certain information presented herein is based on the expectations of the Company
and Detroit Edison, and, as such, is forward-looking. The Private Securities
Litigation Reform Act of 1995 encourages reporting companies to provide analyses
and estimates of future prospects and also permits reporting companies to point
out that actual results may differ from those anticipated.

Actual results for the Company and Detroit Edison may differ from those expected
due to a number of variables including, but not limited to, weather, actual
sales, the effects of competition and the phased-in implementation of Direct
Access, the implementation of utility restructuring in Michigan (which involves
pending regulatory proceedings, possible legislative activity, and the recovery
of stranded costs), environmental (including proposed regulations to limit
nitrogen oxide emissions) and nuclear requirements, the impact of FERC
proceedings and regulations, the success of non-regulated lines of business and
the timely completion of Year 2000 modifications. While the Company and Detroit
Edison believe that estimates given accurately measure the expected outcome,
actual results could vary materially due to the variables mentioned as well as
others. This discussion contains a Year 2000 readiness disclosure.

Analysis of Financial Condition and Results of Operations," which is

                           PART II - OTHER INFORMATION

ITEM 1 - LEGAL PROCEEDINGS.

In a lawsuit filed in January 1999 in the Circuit Court for Wayne County
Michigan (Cook, et al v. Detroit Edison), a number of individual plaintiffs have
claimed employment-related sex, gender and race discrimination, as well as
harassment. The suit seeks certification as a class action. Detroit Edison
believes the claims are without merit.

As discussed in "Part I, Item 1 - Business" in the Company's Annual Report, in
1998 Detroit Edison attempted to restart the Conners Creek Power Plant (in
reserve status from 1988 to 1998) to meet expected high summer demand for
electricity. Although Detroit Edison believed that the plant complied with all
applicable environmental requirements, several regulatory agencies contended
that Detroit Edison was required to obtain a series of new permits prior to
plant operation and issued notices of violation. In August 1998, Detroit Edison
filed suit seeking a review of the agencies' determinations. On January 11,
1999, the Department of Justice (DOJ) on behalf of the EPA sent Detroit Edison a
Demand Letter requiring the payment of $2.3 million in civil penalties and an
unconditional commitment to abandon the use of the facility as a coal plant.
Detroit Edison rejected the demand and on January 15, 1999 the DOJ/EPA filed
suit in United States District Court for the Eastern District of Michigan. An
interim order issued on March 11, 1999 required Detroit Edison to convert the
plant from a coal to a natural gas fired facility. The ruling is the preliminary
outcome of the lawsuit filed by Detroit Edison seeking resolution of the
regulatory issues challenging any use of the plant. The operation of the plant
by early summer 1999 was found to be necessary to protect the health, safety and
welfare of the people of the Detroit metropolitan area. Resolution of the
remaining issues is proceeding. The cost of the conversion is estimated at $11
million. It is impossible to predict what impact, if any, the final outcome of
this will have upon Detroit Edison.

ITEM 5 - OTHER INFORMATION.

On March 31, 1999, Detroit Edison filed for reconciliation of its MPSC
jurisdictional 1998 PSCR revenues and expenses. Detroit Edison indicated that an
under recovery of $45.5 million, including interest, existed, and when offset by
a Fermi 2 performance standard credit of $33.7 million, a net amount of $11.8
million remains to be collected from PSCR customers.

                               DTE ENERGY COMPANY

                         AS AMENDED THROUGH MAY 1, 1998


                                    ARTICLE I

                                  SHAREHOLDERS

         Section 1. ANNUAL MEETING. The annual meeting of the shareholders of
the Company shall be held on the fourth Wednesday of April in each year (or if
said day be a legal holiday, then on the next succeeding day not a legal
holiday), at such time and at such place as may be fixed by the Board of
Directors and stated in the notice of meeting, for the purpose of electing
directors and transacting such other business as may properly be brought before
the meeting as determined by Article I, Section 8 hereof.

         Section 2. SPECIAL MEETINGS. Special meetings of the shareholders may
be held upon call of the Board of Directors or the Chairman of the Board or the
President or the holders of record of three-quarters of the outstanding shares
of stock of the Company entitled to vote at such meeting, at such time as may be
fixed by the Board of Directors or the Chairman of the Board or the President or
such shareholders and stated in the notice of meeting. All such meetings shall
be held at the office of the Company in the City of Detroit unless some other
place is specified in the notice.

         Section 3. NOTICE OF MEETINGS. Written notice of the date, time, place
and purpose or purposes of every meeting of the shareholders, signed by the
Corporate Secretary or an Assistant Corporate Secretary, shall be given either
personally or by mail, within the time prescribed by law, to each shareholder of
record entitled to vote at such meeting and to any shareholder who, by reason of
any action proposed to be taken at such meeting, might be entitled to receive
payment for such stock if such action were taken. If mailed, such notice is
given when deposited in the United States mail, with postage prepaid, directed
to the shareholder at the address as it appears on the record of shareholders,
or, if the shareholders shall have filed with the Corporate Secretary of the
Company a written request that notices intended for such shareholder be mailed
to some other address, then directed to the address designated in such request.
Further notice shall be given by mail, publication, or otherwise, if and as
required by law.

         Notice of meeting need not be given to any shareholder who submits a
signed waiver of notice, in person or by proxy, whether before or after the
meeting. 

                                       1
<PAGE>   5

The attendance of any shareholder at the meeting, in person or by
proxy, without protesting at the beginning of the meeting the lack of notice of
such meeting, shall constitute a waiver of notice by such shareholder.

         Notice of a special meeting shall also indicate that it is being issued
by or at the direction of the person or persons calling the meeting.
         Section 4. QUORUM. At every meeting of the shareholders, the holders of
record of a majority of the outstanding shares of stock of the Company entitled
to vote at such meeting, whether present in person or represented by proxy,
shall constitute a quorum. If at any meeting there shall be no quorum, the
holders of a majority of the outstanding shares of stock so present or
represented may adjourn the meeting from time to time, without notice (unless
otherwise required by statute) other than announcement at the meeting, until a
quorum shall have been obtained, when any business may be transacted which might
have been transacted at the meeting as first convened had there been a quorum.
When a quorum is once present to organize a meeting, it is not broken by the
subsequent withdrawal of any shareholder.

         Section 5. VOTING AND INSPECTORS. Except as provided in the Articles of
Incorporation, each holder of record of outstanding shares of stock of the
Company entitled to vote at a meeting of shareholders shall be entitled to one
vote for each share of stock standing in the shareholder's name on the record of
shareholders, and may so vote either in person or by proxy appointed by
instrument in writing executed by such holder or by the shareholder's duly
authorized attorney-in-fact. No proxy shall be valid after the expiration of
three years from the date of its execution unless the shareholder executing it
shall have specified the length of time it is to continue in force which shall
be for some limited period. The authority of the holder of a proxy to act shall
not be revoked by the incompetence or death of the shareholder who executed the
proxy unless, before the authority is exercised, written notice of an
adjudication of such incompetence or of such death is received by the Corporate
Secretary or an Assistant Corporate Secretary.

         In advance of any meeting of shareholders, the Board of Directors may
appoint one or more inspectors for the meeting. If inspectors are not so
appointed, the chairman of the meeting shall appoint such inspectors. Before
entering upon the discharge of their duties, the inspectors shall take and
subscribe an oath faithfully to execute the duties of inspector at such meeting
with strict impartiality and according to the best of their ability, and shall
take charge of the polls and after balloting shall make a certificate of the
result of the vote taken. No officer or director of the Company or candidate for
office of director shall be appointed as an inspector. At all elections of
directors the voting shall be by ballot and a plurality of the votes cast shall
elect. 

         Section 6. RECORD OF SHAREHOLDERS. For the purpose of determining the
shareholders entitled to notice of or to vote at any meeting of shareholders or
any adjournment thereof, or to express consent to or dissent from any proposal
without 

                                       2
<PAGE>   6

a meeting, or for the purpose of determining shareholders entitled to
receive payment of any dividend or the allotment of any rights, or for the
purpose of any other action, the Board of Directors may fix, in advance, a date
as the record date for any such determination of shareholders. The record date
shall not precede the date upon which it is fixed and shall not be less than 10
days nor more than the maximum number of days permitted by law before the date
of the meeting, or taking of any other action.

         Section 7. LIST OF SHAREHOLDERS. A list of shareholders of record,
arranged alphabetically within each class and series of stock, as of the record
date, certified by the Corporate Secretary or any Assistant Corporate Secretary
or by a transfer agent, shall be produced at any meeting of shareholders and may
be inspected by any shareholder at any time during the meeting. If the right to
vote at any meeting is challenged, the inspectors, or the chairman presiding at
the meeting, shall require such list of shareholders to be produced as evidence
of the right of the

                                       3
<PAGE>   7


persons challenged to vote at such meeting, and all persons who appear on such
list to be shareholders entitled to vote thereat may vote at such meeting.

         SECTION 8. ORDER OF BUSINESS. (a) The Chairman, or such other officer
of the Company designated by a majority of the total number of directors that
the Company would have if there were no vacancies on the Board of Directors
(such number being referred to as the "Whole Board"), will call meetings of
shareholders to order and will act as presiding officer thereof. Unless
otherwise determined by the Board of Directors prior to the meeting, the
presiding officer of the meeting of shareholders will also determine the order
of business and have the authority in his or her sole discretion to regulate the
conduct of any such meeting including, without limitation, by imposing
restrictions on the persons (other than shareholders of the Company or their
duly appointed proxies) who may attend any such shareholders' meeting, by
ascertaining whether any shareholder or his proxy may be excluded from any
meeting of shareholders based upon any determination by the presiding officer,
in his or her sole discretion, that any such person has unduly disrupted or is
likely to disrupt the proceedings of the meeting, and by determining the
circumstances in which any person may make a statement or ask questions at any
meeting of shareholders.

         (b) At an annual meeting of the shareholders, only such business will
be conducted or considered as is properly brought before the meeting. To be
properly brought before an annual meeting, business must be (i) specified in the
notice of meeting (or any supplement thereto) given by or at the direction of
the Chairman, the President, a Vice President, the Corporate Secretary or an
Assistant Corporate Secretary in accordance with Section 3 of this Article I;
(ii) otherwise properly brought before the meeting by the presiding officer or
by or at the direction of a majority of the Whole Board; or (iii) otherwise
properly requested to be brought before the meeting by a shareholder of the
Company in accordance with Section 8(c) below.


         (c) For business to be properly requested by a shareholder to be
brought before an annual meeting, the shareholder must (i) be a shareholder of
the Company of record at the time of the giving of the notice for such annual
meeting provided for in these Bylaws; (ii) be entitled to vote at such meeting;
and (iii) have given timely notice thereof in writing to the Corporate
Secretary. To be timely, a shareholder's notice must be delivered to or mailed
and received at the principal executive offices of the Company not less than 60
nor more than 90 calendar days prior to the annual meeting; provided, however,
that in the event public announcement of the date of the annual meeting is not
made at least 100 calendar days prior to the date of the annual meeting, notice
by the shareholder to be timely must be so received not later than the close of
business on the 10th calendar day following the day on which public announcement
is first made of the date of the annual meeting. A shareholder's notice to the
Corporate Secretary must set forth as to each matter the shareholder proposes to
bring before the annual meeting: (a) 

                                       4
<PAGE>   8

a description in reasonable detail of the business desired to be brought before
the annual meeting and the reasons for conducting such business at the annual
meeting; (b) the name and address, as they appear on the Company's books, of the
shareholder proposing such business and of the beneficial owner, if any, on
whose behalf the proposal is made; (c) the class and number of shares of the
Company that are owned beneficially and of record by the shareholder proposing
such business and by the beneficial owner, if any, on whose behalf the proposal
is made; and (d) any material interest in such business of such shareholder
proposing such business and the beneficial owner, if any, on whose behalf the
proposal is made. Notwithstanding the foregoing provisions of this Section 8(c),
a shareholder must also comply with all applicable requirements of the
Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder with respect to the matters set forth in this Section 8(c). For
purposes of this Section 8(c) and Section 3 of Article II, "public announcement"
means disclosure in a press release reported by the Dow Jones News Service,
Associated Press, or comparable national news service or in a document publicly
filed by the Company with the Securities and Exchange Commission pursuant to
Sections 13, 14, or 15(d) of the Securities Exchange Act of 1934, as amended, or
publicly filed by the Company with any national securities exchange or quotation
service through which the Company's stock is listed or traded, or furnished by
the Company to its shareholders. Nothing in this Section 8(c) will be deemed to
affect any rights of shareholders to request inclusion of proposals in the
Company's proxy statement pursuant to Rule 14a-8 under the Securities Exchange
Act of 1934, as amended.

         (d) At a special meeting of shareholders, only such business may be
conducted or considered as is properly brought before the meeting. To be
properly brought before a special meeting, business must be (i) specified in the
notice of the meeting (or any supplement thereto) given by or at the direction
of the Chairman, the President, a Vice President, the Corporate Secretary or an
Assistant Corporate Secretary (or in case of their failure to give any required
notice, the other persons entitled to give notice) in accordance with Section 3
of Article I or (ii) otherwise brought before the meeting by the presiding
officer or by or at the direction of a majority of the Whole Board.

         (e) The determination of whether any business sought to be brought
before any annual or special meeting of the shareholders is properly brought
before such meeting in accordance with this Section 8 will be made by the
presiding officer of such meeting. If the presiding officer determines that any
business is not properly brought before such meeting, he or she will so declare
to the meeting and any such business will not be conducted or considered.


                                   ARTICLE II

                        BOARD OF DIRECTORS AND COMMITTEES

                                       5
<PAGE>   9

         Section 1. NUMBER, TIME OF HOLDING OFFICE AND LIMITATION ON AGE. The
business and affairs of the Company shall be managed by or under the direction
of a Board of Directors. The number of directors constituting the Whole Board
shall be determined from time to time by resolution of the Board so long as the
total number of directors is not less than ten nor more than eighteen; provided,
however, that the minimum and maximum number of directors may be increased or
decreased from time to time by vote of a majority of the Whole Board; and,
further provided that no change in the number of directors shall serve to
shorten the term of office of any incumbent director. The directors shall be
divided into three classes, as nearly equal in number as possible, and the term
of the office of the first class shall expire at the 1996 annual meeting of
shareholders, the term of office of the second class shall expire at the 1997
annual meeting of shareholders and the term of office of the third class shall
expire at the 1998 annual meeting of shareholders, or, in each case, until their
successors shall be duly elected and qualified. At each annual meeting
commencing in 1996, a number of directors equal to the number of the class whose
term expires at the time of the meeting shall be elected to hold office until
the third succeeding annual meeting of shareholders. If at any time the holders
of any series of the Company's Preferred Stock are entitled to elect directors
pursuant to the Articles of Incorporation of the Company, then the provisions of
such series of Preferred Stock with respect to their rights shall apply and such
directors shall be elected in a manner and for terms expiring consistent with
the Articles of Incorporation.

         Except as hereinafter provided, each director shall be a holder of
Common Stock of the Company at the time of initial election to the Board or
shall become a holder within 30 days after such election (to the extent of at
least one share, owned beneficially). Any director who thereafter ceases to be
such a holder, shall thereupon cease to be a director. The Board shall have the
authority to waive the requirement to hold shares in individual situations upon
presentation of evidence that a nominee or director is unable to hold shares for
legal or religious reasons.

         No person who shall have served as an employee of the Company or an
affiliate shall be elected a director after retiring from employment with the
Company or an affiliate; provided, however, that if such person was the Chief
Executive Officer of the Company at the time of such retirement, such person
shall be eligible for election as a director until attaining age 70. No other
person shall be elected a director after attaining age 70; provided, however,
the Board shall have the authority to waive this provision for no more than one
three-year term upon a determination that circumstances exist which make it
prudent to continue the service of a director who possesses special and unique
expertise clearly beneficial to the Company.

         Section 2. VACANCIES. Whenever any vacancy shall occur in the Board of
Directors by death, resignation, or any other cause, it shall be filled without
undue delay by a majority vote of the remaining members of the Board of
Directors (even if constituting less than a quorum), and the person who is to
fill any such 

                                       6
<PAGE>   10

vacancy shall hold office for the unexpired term of the director to whom such
person succeeds, or for the term fixed by the Board of Directors acting in
compliance with Section l of this Article II in case of a vacancy created by an
increase in the number of directors, and until a successor shall be elected and
shall have qualified; provided, however, that no vacancy need be filled if,
after such vacancy shall occur, the number of directors remaining on the Board
shall be not less than a majority of the Whole Board. During the existence of
any vacancy or vacancies, the surviving or remaining directors shall possess and
may exercise all the powers of the full Board of Directors, when action by a
larger number is not required by law.

         SECTION 3. NOMINATIONS OF DIRECTORS; ELECTION. (a) Except as may be
otherwise provided in any resolution establishing any Preferred Stock, only
persons who are nominated in accordance with this Section 3 will be eligible for
election at a meeting of shareholders to be members of the Board of Directors of
the Company.

         (b) Nominations of persons for election as directors of the Company may
be made only at an annual meeting of shareholders (i) by or at the direction of
the Board of Directors or a committee thereof or (ii) by any shareholder who is
a shareholder of record at the time of giving of notice provided for in this
Section 3, who is entitled to vote for the election of directors at such
meeting, and who complies with the procedures set forth in this Section 3. All
nominations by shareholders must be made pursuant to timely notice in proper
written form to the Corporate Secretary.

         (c) To be timely, a shareholder's notice must be delivered to or mailed
and received at the principal executive offices of the Company not less than 60
nor more than 90 calendar days prior to the annual meeting of shareholders;
provided, however, that in the event that public announcement of the date of the
annual meeting is not made at least 100 calendar days prior to the date of the
annual meeting, notice by the shareholder to be timely must be so received not
later than the close of business on the 10th calendar day following the day on
which public announcement (as defined in Section 8(c ) of Article I) is first
made of the date of the annual meeting. To be in proper written form, such
shareholder's notice must set forth or include: (i) the name and address, as
they appear on the Company's books, of the shareholder giving the notice and of
the beneficial owner, if any, on whose behalf the nomination is made; (ii) a
representation that the shareholder giving the notice is a holder of record of
stock of the Company entitled to vote at such annual meeting and intends to
appear in person or by proxy at the annual meeting to nominate the person or
persons specified in the notice; (iii) the class and number of shares of stock
of the Company owned beneficially and of record by the shareholder giving the
notice and by the beneficial owner, if any, on whose behalf the nomination is
made; (iv) a description of all arrangements or understandings between or among
any of (A) the shareholder giving the notice, (B) the beneficial owner on whose
behalf the notice is given, (C) each nominee, and (D) 

                                       7
<PAGE>   11

any other person or persons (naming such person or persons) pursuant to which
the nomination or nominations are to be made by the shareholder giving the
notice; (v) such other information regarding each nominee proposed by the
shareholder giving the notice as would be required to be included in a proxy
statement filed pursuant to the proxy rules of the Securities and Exchange
Commission had the nominee been nominated, or intended to be nominated, by the
Board of Directors; and (vi) the signed consent of each nominee to serve as a
director of the Company if so elected. The presiding officer of any annual
meeting may, if the facts warrant, determine that a nomination was not made in
accordance with this Section 3, and if he or she should so determine, he or she
will so declare to the meeting, and the defective nomination will be
disregarded. Notwithstanding the foregoing provisions of this Section 3, a
shareholder must also comply with all applicable requirements of the Securities
Exchange Act of 1934, as amended, and the rules and regulations thereunder with
respect to the matters set forth in this Section 3.


         Section 4. MEETINGS OF THE BOARD. Regular meetings of the Board of
Directors shall be held at such times and at such places as may from time to
time be fixed by the Board of Directors.

         Special meetings of the Board of Directors may be called by the
Chairman of the Board, the President, or, in the event of the incapacity of the
Chairman of the Board and the President, the Executive Committee by giving
reasonable notice of the time and place of such meetings or by obtaining written
waivers of notice, before or after the meeting, from each absent director. All
such meetings shall be held at the office of the Company in the City of Detroit
unless some other place is specified in the notice.

         A notice, or waiver of notice, need not specify the purpose of the
meeting.

         Section 5. QUORUM. A majority of the directors in office at the time of
a meeting of the Board, shall constitute a quorum for the transaction of
business. If at any meeting of the Board of Directors there shall be less than a
quorum present, a majority of the directors present may adjourn the meeting
without notice other than announcement at the meeting, until a quorum shall have
been obtained, when any business may be transacted which might have been
transacted at the meeting as first convened had there been a quorum. The acts of
a majority of the directors present at any meeting at which there is a quorum
shall be the acts of the Board, unless otherwise provided by law, by the
Articles of Incorporation or by the Bylaws.

         Section 6. ANNUAL MEETING OF DIRECTORS. A meeting of the Board of
Directors, known as the directors' annual meeting, shall be held without notice
each year after the adjournment of the annual shareholders' meeting and on the
same day. At such meeting the officers of the Company for the ensuing year shall

                                       8
<PAGE>   12

be elected. If a quorum of the directors is not present on the day appointed for
the directors' annual meeting, the meeting shall be adjourned to some convenient
day.

         Section 7. EXECUTIVE COMMITTEE. The Board of Directors may, by
resolution or resolutions passed by a majority of the Whole Board, designate an
Executive Committee to consist of the Chief Executive Officer and two or more of
the other directors, and alternates, and shall designate the Chairman thereof.
The Executive Committee shall have and may exercise, when the Board is not in
session, all of the powers of the Board in the management of the business and
affairs of the Company, and shall have power to authorize the seal of the
Company to be affixed to all papers which may require it. The Executive
Committee shall not have power to (a) amend these Bylaws, (b) change the number
of directors constituting the Whole Board or fill vacancies in the Board, (c)
declare dividends, (d) establish, change the membership of, or fill vacancies
in, any committee, (e) fix the compensation of the directors or committee
members, (f) submit matters for action by shareholders, or (g) amend or repeal a
resolution of the Board which by its terms may not be changed by the Executive
Committee. The Board shall have the power at any time to fill vacancies in, to
change the membership of, or to dissolve, the Executive Committee. The Executive
Committee may make rules for the conduct of its business and may appoint such
subcommittees and assistants as it shall from time to time deem necessary. A
majority of the members of the Executive Committee shall constitute a quorum.
All action taken by the Executive Committee shall be reported to the Board at
its next meeting succeeding such action. The Corporate Secretary or an Assistant
Corporate Secretary shall attend and act as the secretary of all meetings of the
Committee and keep the minutes thereof.

         Meetings of the Executive Committee may be called by the Chairman of
the Board, or, the President, or, in the event of the incapacity of the Chairman
of the Board and the President, by two or more members of the Executive
Committee by giving reasonable notice of the time and place of such meetings.
All such meetings shall be held at the office of the Company in the City of
Detroit unless some other place is specified in the notice.

         Section 8. COMMITTEES. The Board of Directors may, by resolution,
create a committee or committees of one or more directors, and alternates, to
consider and report upon or to

                                       9
<PAGE>   13


carry out such matters (not excepted by Article II, Section 7) as may be
entrusted to them by the Board of Directors, and shall designate the Chairman of
each such committee.

         Section 9. PARTICIPATION IN MEETINGS. One or more members of the Board
of Directors or any committee may participate in any meeting of such Board or
such committee by means of a conference telephone or similar communications
equipment which enables all persons participating in such a meeting to hear each
other at the same time. Participation in the manner so described shall
constitute presence in person at such meetings. 

         Section 10. COMPENSATION. Each director of the Company who is not a
salaried officer or employee of the Company may receive reasonable compensation
for services as a director, including a reasonable fee for attendance at
meetings of the Board and committees thereof, and attendance at the Company's
request at other meetings or similar activities related to the Company.


                                   ARTICLE III

                                    OFFICERS

         Section 1. OFFICERS AND AGENTS. The officers of the Company to be
elected by the Board of Directors, as soon as practicable after the election of
directors each year, shall be Chairman of the Board, the President, a Corporate
Secretary and a Treasurer. The Board of Directors may also from time to time
elect one or more Vice Presidents, a Controller, a General Auditor, a General
Counsel, and such other officers and agents as it may deem proper. The Chairman
of the Board and the President shall be chosen from among the directors. The
persons holding the offices of Chairman of the Board or President may not also
hold the office of General Auditor. The Board of Directors may, in its
discretion, leave vacant any office other than that of Chairman of the Board,
President, Corporate Secretary, or Treasurer.

         Section 2. TERM OF OFFICE. The term of office of all officers shall be
until the next directors' annual meeting or until their respective successors
are chosen and qualified. Any officer or agent elected by the Board of Directors
may be removed by the Board at any time, with or without cause.

         Section 3. CHAIRMAN OF THE BOARD. The Chairman of the Board shall be
the Chief Executive Officer of the Company and, shall preside at all meetings of
the Board of Directors and, subject to Section 8(a) of Article I, meetings of
shareholders, at which the Chairman is present, and shall make the annual report
to the shareholders. The Chairman shall have general charge of the business and
affairs of the Company subject to the control of the Board of Directors, may
create

in the name of the Company any authorized corporate obligation or other
instrument and shall perform such other functions as may be prescribed by the
Board from time to time.

Company and its agents to such extent and in such manner as the Board of
Directors may from time to time prescribe.

officers or agent or agents, either manually or by facsimile signature or
signatures, as shall be thereunto authorized from time to time by the Board of
Directors either generally or in specific instances; provided that bonds,
debentures, and other evidences of indebtedness of the Company bearing facsimile
signatures of officers of the Company shall be issued only when authenticated by
a manual signature on behalf of a trustee or an authenticating agent appointed
by the Board of Directors. In case any such officer of the Company shall cease
to be such after such officer's facsimile signature has been placed thereon,

same effect as if such person were still in office.

                           THE DETROIT EDISON COMPANY


                         AS AMENDED THROUGH MAY 1, 1998

                                    ARTICLE I

                                  SHAREHOLDERS

         Section 1. ANNUAL MEETING. The annual meeting of the shareholders of
the Company shall be held on the fourth Wednesday of April in each year (or if
said day be a legal holiday, then on the next succeeding day not a legal
holiday), at such time and at such place as may be fixed by the Board of
Directors and stated in the notice of meeting, for the purpose of electing
directors and transacting such other business as may properly be brought before
the meeting as determined by Article I, Section 8 hereof.

         Section 2. SPECIAL MEETINGS. Special meetings of the shareholders may
be held upon call of the Board of Directors or the Chairman of the Board or the
President or the holders of record of three-quarters of the outstanding shares
of stock of the Company, at such time as may be fixed by the Board of Directors
or the Chairman of the Board or the President or such shareholders and stated in
the notice of meeting. All such meetings shall be held at the office of the
Company in the City of Detroit unless some other place is specified in the
notice.

         Section 3. NOTICE OF MEETINGS. Written notice of the date, time, place
and purpose or purposes of every meeting of the shareholders, signed by the
Corporate Secretary or an Assistant Corporate Secretary, shall be given either
personally or by mail, within the time prescribed by law, to each shareholder of
record entitled to vote at such meeting and to any shareholder who, by reason of
any action proposed at such meeting, might be entitled to receive payment for
such stock if such action were taken. If mailed, such notice is given when
deposited in the United States mail, with postage thereon prepaid, directed to
the shareholder at the address as it appears on the record of shareholders, or,
if the shareholders shall have filed with the Corporate Secretary of the Company
a written request that notices intended for such shareholder be mailed to some
other address, then directed to the address designated in such request. Further
notice shall be given by mail, publication, or otherwise, if and as required by
law.

         Notice of meeting need not be given to any shareholder who submits a
signed waiver of notice, in person or by proxy, whether before or after the
meeting. The attendance of any shareholder at the meeting, in person or by
proxy, without protesting at the beginning of the meeting the lack of notice of
such meeting, shall constitute a waiver 

                                       1
<PAGE>   5

of notice by such shareholder.

         Notice of a special meeting shall also indicate that it is being issued
by or at the direction of the person or persons calling the meeting.

         Section 4. QUORUM. At every meeting of the shareholders, the holders of
record of a majority of the outstanding shares of stock of the Company entitled
to vote at such meeting, whether present in person or represented by proxy,
shall constitute a quorum. If at any meeting there shall be no quorum, the
holders of a majority of the outstanding shares of stock so present or
represented may adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall have been obtained, when any
business may be transacted which might have been transacted at the meeting as
first convened had there been a quorum. When a quorum is once present to
organize a meeting, it is not broken by the subsequent withdrawal of any
shareholder.

         Section 5. VOTING AND INSPECTORS. Each holder of record of outstanding
shares of stock of the Company entitled to vote at a meeting of shareholders
shall be entitled to one vote for each share of stock standing in the
shareholder's name on the record of shareholders, and may so vote either in
person or by proxy appointed by instrument in writing executed by such holder or
by the shareholder's duly authorized attorney-in-fact. No proxy shall be valid
after the expiration of three years from the date of its execution unless the
shareholder executing it shall have specified the length of time it is to
continue in force which shall be for some limited period. The authority of the
holder of a proxy to act shall not be revoked by the incompetence or death of
the shareholder who executed the proxy unless, before the authority is
exercised, written notice of an adjudication of such incompetence or of such
death is received by the Corporate Secretary or an Assistant Corporate
Secretary.

         In advance of any meeting of shareholders, the Board of Directors may
appoint one or more inspectors for the meeting. If inspectors are not so
appointed, the chairman of the meeting shall appoint such inspectors. Before
entering upon the discharge of their duties, the inspectors shall take and
subscribe an oath faithfully to execute the duties of inspector at such meeting
with strict impartiality and according to the best of their ability, and shall
take charge of the polls and after balloting shall make a certificate of the
result of the vote taken. No officer or director of the Company or candidate for
office of director shall be appointed as an inspector. At all elections of
directors, the voting shall be by ballot and a plurality of the votes cast shall
elect.
         Section 6. RECORD OF SHAREHOLDERS. For the purpose of determining the
shareholders entitled to notice of or to vote at any meeting of shareholders or
any adjournment thereof, or to express consent to or dissent from any proposal
without a meeting, or for the purpose of determining shareholders entitled to
receive payment of any dividend or the allotment of any rights, or for the
purpose of any other action, the Board of Directors may fix, in advance, a date
as the record date for any such determination of shareholders, which record date
shall not less than 10 days nor more than the maximum number of days permitted
by law before the date of the meeting, or taking of any other action.

                                       2
<PAGE>   6

         Section 7. LIST OF SHAREHOLDERS. A list of shareholders as of the
record date, certified by the Corporate Secretary or any Assistant Corporate
Secretary or by a transfer agent, shall be produced at any meeting of
shareholders upon the request thereat or prior thereto of any shareholder. If
the right to vote at any meeting is challenged, the inspectors, or the person
presiding at the meeting, shall require such list of shareholders to be produced
as evidence of the right of the persons challenged to vote at such meeting, and
all persons who appear on such list to be shareholders entitled to vote thereat
may vote at such meeting.

         Section 8. ORDER OF BUSINESS. (a) The Chairman, or such other officer
of the Company designated by a majority of the total number of directors that
the Company would have if there were no vacancies on the Board of Directors
(such number being referred to as the "Whole Board"), will call meetings of
shareholders to order and will act as presiding officer thereof. Unless
otherwise determined by the Board of Directors prior to the meeting, the
presiding officer of the meeting of shareholders will also determine the order
of business and have the authority in his or her sole discretion to regulate the
conduct of any such meeting including, without limitation, by imposing
restrictions on the persons (other than shareholders of the Company or their
duly appointed proxies) who may attend any such shareholders' meeting, by
ascertaining whether any shareholder or his proxy may be excluded from any
meeting of shareholders based upon any determination by the presiding officer,
in his or her sole discretion, that any such person has unduly disrupted or is
likely to disrupt the proceedings of the meeting, and by determining the
circumstances in which any person may make a statement or ask questions at any
meeting of shareholders.

         (b) At an annual meeting of the shareholders, only such business will
be conducted or considered as is properly brought before the meeting. To be
properly brought before an annual meeting, business must be (i) specified in the
notice of meeting (or any supplement thereto) given by or at the direction of
the Chairman, the President, a Vice President, the Corporate Secretary or an
Assistant Corporate Secretary in accordance with Section 3 of this Article I;
(ii) otherwise properly brought before the meeting by the presiding officer or
by or at the direction of a majority of the Whole Board; or (iii) otherwise
properly requested to be brought before the meeting by a shareholder of the
Company in accordance with Section 8(c) below.

         (c) For business to be properly requested by a shareholder to be
brought before an annual meeting, the shareholder must (i) be a shareholder of
the Company of record at the time of the giving of the notice for such annual
meeting provided for in these Bylaws; (ii) be entitled to vote at such meeting;
and (iii) have given timely notice thereof in writing to the Corporate
Secretary. To be timely, a shareholder's notice must be delivered to or mailed
and received at the principal executive offices of the Company not less than 60
nor more than 90 calendar days prior to the annual meeting; provided, however,
that in the event public announcement of the date of the annual meeting is not
made at least 100 calendar days prior to the date of the annual meeting, notice
by the shareholder to be timely must be so received not later than the close of
business on the 10th calendar day following the day on which public announcement
is first made of the date of the annual 

                                       3
<PAGE>   7

meeting. A shareholder's notice to the Corporate Secretary must set forth as to
each matter the shareholder proposes to bring before the annual meeting: (A) a
description in reasonable detail of the business desired to be brought before
the annual meeting and the reasons for conducting such business at the annual
meeting; (B) the name and address, as they appear on the Company's books, of the
shareholder proposing such business and of the beneficial owner, if any, on
whose behalf the proposal is made; (C) the class and number of shares of the
Company that are owned beneficially and of record by the shareholder proposing
such business and by the beneficial owner, if any, on whose behalf the proposal
is made; and (D) any material interest in such business of such shareholder
proposing such business and the beneficial owner, if any, on whose behalf the
proposal is made. Notwithstanding the foregoing provisions of this Section 8(c),
a shareholder must also comply with all applicable requirements of the
Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder with respect to the matters set forth in this Section 8(c). For
purposes of this Section 8(c) and Section 3 of Article II, "public announcement"
means disclosure in a press release reported by the Dow Jones News Service,
Associated Press, or comparable national news service or in a document publicly
filed by the Company with the Securities and Exchange Commission pursuant to
Sections 13, 14, or 15(d) of the Securities Exchange Act of 1934, as amended, or
publicly filed by the Company with any national securities exchange or quotation
service through which the Company's

                                       4
<PAGE>   8


stock is listed or traded, or furnished by the Company to its shareholders.
Nothing in this Section 8(c) will be deemed to affect any rights of shareholders
to request inclusion of proposals in the Company's proxy statement pursuant to
Rule 14a-8 under the Securities Exchange Act of 1934, as amended.

         (d) At a special meeting of shareholders, only such business may be
conducted or considered as is properly brought before the meeting. To be
properly brought before a special meeting, business must be (i) specified in the
notice of the meeting (or any supplement thereto) given by or at the direction
of the Chairman, the President, a Vice President, the Corporate Secretary or an
Assistant Corporate Secretary (or in case of their failure to give any required
notice, the other persons entitled to give notice) in accordance with Section 3
of Article I or (ii) otherwise brought before the meeting by the presiding
officer or by or at the direction of a majority of the Whole Board.

         (e) The determination of whether any business sought to be brought
before any annual or special meeting of the shareholders is properly brought
before such meeting in accordance with this Section 8 will be made by the
presiding officer of such meeting. If the presiding officer determines that any
business is not properly brought before such meeting, he or she will so declare
to the meeting and any such business will not be conducted or considered.

                                   ARTICLE II

                        BOARD OF DIRECTORS AND COMMITTEES

         Section 1. NUMBER, TIME OF HOLDING OFFICE AND LIMITATION ON AGE. The
business and affairs of the Company shall be managed and controlled by a Board
of Directors. The number of directors constituting the Whole Board shall be
determined from time to time by resolution of the Board so long as the total
number of directors is not less than ten nor more than eighteen; provided,
however, that the minimum and maximum number of directors may be increased or
decreased from time to time by vote of a majority of the Whole Board; and,
further provided that no change in the number of directors shall serve to
shorten the term of office of any incumbent director. Commencing with the annual
election of directors by the shareholders in 1991, the directors shall be
divided into three classes, as nearly equal in number as possible, and the term
of office of the first class shall expire at the 1992 annual meeting of
shareholders, the term of office of the second class shall expire at the 1993
annual meeting of shareholders and the term of office of the third class shall
expire at the 1994 annual meeting of shareholders, or, in each case, until their
successors shall be duly elected and qualified. At each annual meeting
commencing in 1992, a number of directors equal to the number of the class whose
term expires at the time of the meeting shall be elected to hold office until
the third succeeding annual meeting of shareholders. In the event the holders of
the Preferred Stock or the Preference Stock are entitled to elect directors as
provided in Article V, Division I, subdivision (9) or Article V, Division II,
subdivision (9) of the Restated Articles of Incorporation of the Company, then
the provisions of such class of stock with respect to their rights shall apply
and such directors shall be elected for terms expiring at the next annual
meeting of shareholders and without regard to the classification of the
remaining 

                                       5
<PAGE>   9

members of the Board of Directors.

         Except as hereinafter provided, each director shall be a holder of
Common Stock of DTE Energy Company at the time of initial election to the Board
or shall become a holder within thirty days after such election (to the extent
of at least one share, owned beneficially) and any director who thereafter
ceases to be such a holder, shall thereupon cease to be a director. The Board
shall have the authority to waive the

                                       6
<PAGE>   10


requirement to hold shares in individual situations upon presentation of
evidence that a nominee or director is unable to hold shares for legal or
religious reasons.

         No person who shall have served as an employee of the Company or an
affiliate shall be elected a director after retiring from employment with the
Company or an affiliate; provided, however, that if such person was the Chief
Executive Officer of the Company at the time of such retirement, such person
shall be eligible for election as a director until attaining age 70. No other
person shall be elected a director after attaining age 70; provided, however,
the Board shall have the authority to waive this provision for no more than one
three-year term upon a determination that circumstances exist which make it
prudent to continue the service of a director who possesses special and unique
expertise clearly beneficial to the Company.

         Section 2. VACANCIES. Whenever any vacancy shall occur in the Board of
Directors by death, resignation, or any other cause, it shall be filled without
undue delay by a majority vote of the remaining members of the Board of
Directors and the person who is to fill any such vacancy shall hold office for
the unexpired term of the director to whom such person succeeds, or for the term
fixed by the Board of Directors acting in compliance with Section l of this
Article II in case of a vacancy created by an increase in the number of
directors, and until a successor shall be elected and shall have qualified;
provided, however, that no vacancy need be filled if, after such vacancy shall
occur, the number of directors remaining on the Board shall be not less than a
majority of the whole Board. During the existence of any vacancy or vacancies,
the surviving or remaining directors shall possess and may exercise all the
powers of the full Board of Directors, when action by a larger number is not
required by law.

         Section 3. NOMINATIONS OF DIRECTORS; ELECTION. (a) Except as may be
otherwise provided in any resolution establishing any Preferred or Preference
Stock, only persons who are nominated in accordance with this Section 3 will be

obligations of Trading and/or DTE-CoEnergy may rely upon this 1999 Agreement in
extending credit to Trading and/or DTE-CoEnergy and in accepting Subsidiary's

         NOW, THEREFORE, in consideration of the premises, and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Parent and Subsidiary agree as follows:

         1.   STOCK OWNERSHIP. During the term of this 1999 Agreement, Parent
              will own all of the voting common stock of Subsidiary and The
              Detroit Edison Company ("DECo") now or hereafter issued and

         2.   NEGATIVE PLEDGE. During the term of this 1999 Agreement, Parent
              will not create or suffer to exist any lien, security interest or
              other charge or encumbrance, upon or with respect to any voting
              common stock of DECo from time to time owned by Parent or any
              capital stock of Subsidiary from time to time owned by Parent,
              provided, however, that any restriction on the payment of
              dividends by DECo or Subsidiary contained in any subordinated debt
              instrument, preferred stock or preference stock of DECo or
              Subsidiary shall not constitute a lien, security interest or other
              charge or encumbrance,

         3.   LIQUIDITY PROVISION.  If, during the term of this 1999 Agreement, 
              Subsidiary is unable to make timely payment of such amounts as
              shall be due and payable pursuant to a guarantee issued by
              Subsidiary and running to the benefit of any obligee ("Obligee")
              of Trading and/or DTE-CoEnergy, then, Parent promptly shall
              provide to Subsidiary, at its request, such funds (in the form of
              cash or liquid assets) in an amount sufficient to permit
              Subsidiary to make timely payment in respect of such guarantee. If
              such funds are advanced to Subsidiary as a loan, such loan shall
              be on such terms and conditions, including maturity and rate of
              interest, as Parent and Subsidiary shall agree. Notwithstanding
              the foregoing, any such loan shall be subordinated to any and all
              obligations of Subsidiary owing to any Lender pursuant to the
              terms of the Credit Agreement and such amounts as shall be owing
              pursuant to guarantees issued by Subsidiary for the benefit of
              Obligees of Trading and/or DTE-CoEnergy. Each of the parties
              hereto acknowledges that Parent's obligations hereunder do not
              constitute a guarantee by Parent of the obligations of Subsidiary.

              terminated at any time by written amendment or agreement signed by
              both parties; provided, however, that except as set forth in the
              next succeeding sentence, no amendment to the 1999 Agreement which
              adversely affects the rights of Subsidiary or any Obligee and no
              termination of this 1999 Agreement shall be effective as to
              Subsidiary or any Obligee until such time as all amounts
              contingently owing to all Obligees by Subsidiary on the date of
              such amendment or termination shall have been paid in full or
              adequate provision has been made for the payment of same unless
              such Obligees shall consent in writing to the contrary.

         6.   RIGHTS OF OBLIGEE. Subsidiary hereby grants to the Obligees,
              Subsidiary's rights under Sections 1, 2, 3 and 4 of this 1999
              Agreement, and, if Subsidiary fails or refuses to take timely
              action to enforce its rights under Sections 1, 2, 3 or 4 of this
              1999 Agreement, any Obligee may enforce such rights on behalf of
              Subsidiary directly against Parent. Parent hereby consents to such
              grant.

         7.   PARITY. Parent's obligations hereunder shall be pari passau with
              Parent's obligations (a) under that certain Support Agreement
