             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
    DTE ENERGY COMPANY, THE DETROIT EDISON COMPANY AND SUBSIDIARY COMPANIES

NOTE 1 - ANNUAL REPORT NOTES

     These consolidated financial statements 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 preceding 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 - FERMI 2

     As discussed in Note 2 of the Annual Report Notes, on January 17, 1997,
the Fermi 2 plant was shut down for inspection of the internal components of
the plant's generator and required repairs and testing.  Detroit Edison expects
that the unit will be back in service during the second quarter of 1997.  The
costs of the repairs are expected to be covered by insurance.  During the first
quarter of 1997, $24 million was recorded for additional Fermi 2 capacity
factor performance standard disallowances that are expected to be imposed by
the MPSC for the period 1997 - 1999, principally as a result of the outage
period caused by this shutdown.

     Effective April 1, 1997, extra expense insurance, which includes certain
replacement power costs, is available following a 17 week deductible.

NOTE 3 - COMMITMENTS AND CONTINGENCIES

     As discussed in Note 12 of the Annual Report Notes, a class action is
pending in the Circuit Court for Wayne County, Michigan (Gilford, et al v
Detroit Edison) in which plaintiffs are alleging that Detroit Edison has
engaged in age and racial discrimination.  A notice was sent to potential class
members; and in response to such notice, approximately 1,000 individuals have
opted out of the class and approximately 450 individuals have given information
of purported discriminatory treatment.  Approximately 2,750 individuals have
not responded in any fashion to the notice.  Detroit Edison is of the opinion
that the allegations of discrimination are without merit.

                                       14


<PAGE>   15



     As discussed in Note 12 of the Annual Report Notes, in January 1989, the
EPA issued an administrative order under the Comprehensive Environmental
Response, Compensation and Liability Act ordering Detroit Edison and 23 other
potentially responsible parties to begin removal activities at the Carter
Industrials Superfund site.  Clean-up of the Carter Industrials site began in
1995 and was completed in the spring of 1996.  An additional clean-up of the
sewer and sewer out-fall emptying into the Detroit River was completed in
November 1996.  On March 25, 1997, the EPA published its decision to remove the
site from the National Priorities List.

                     ----------------------------------

     This Quarterly Report on Form 10-Q, including the report of Deloitte &
Touche LLP (on page 16) will automatically be incorporated by reference in the
Prospectuses constituting part of the Registration Statements on Form S-3

Form S-8 (Registration No. 333-00023) and Form S-3 (Registration No. 33-57545)
of DTE Energy Company, filed under the Securities Act of 1933.  Such report of

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 subsidiary
companies and of The Detroit Edison Company and subsidiary companies as of
December 31, 1996, and the related consolidated statements of income, common
shareholders' equity, and cash flows for the year then ended (not presented
herein); and in our report dated January 27, 1997 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, 1996 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.
             DTE ENERGY COMPANY, THE DETROIT EDISON COMPANY AND SUBSIDIARY
             COMPANIES


     This analysis for the three and twelve months ended March 31, 1997, as
compared to the same periods in 1996, should be read in conjunction with the
consolidated financial statements (unaudited), the accompanying Notes and the
Annual Report Notes.

     Detroit Edison is the principal subsidiary of the Company and, as such,
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.  For the periods presented, the Company's
operations and those of Detroit Edison are substantially the same.

RESULTS OF OPERATIONS

     For the three months ended March 31, 1997, the Company's net income was
$71.0 million, or $0.49 per common share, down 34.5 percent from the $108.4
million, or $0.75 per common share earned in the three months ended March 31,
1996.  For the twelve months ended March 31, 1997, the Company's net income was
$271.9 million, or $1.87 per common share, down 33 percent from the $408.3
million, or $2.82 per common share earned in the twelve months ended March 31,
1996.  The decreases in net income were due primarily to a repair and
maintenance outage at Fermi 2 which increased the Fermi 2 capacity factor
performance standard reserve for the period 1997-1999, lower electricity sales
and, to a lesser extent, the cost of responding to the March 1997 catastrophic
ice storm.  In addition, for the twelve-month period, a $149.2 million ($97
million after-tax), or $0.67 per common share, special charge to net income was
made in the third quarter of 1996 following completion of Detroit Edison's 
review of its steam heating operations.

     At March 31, 1997, the book value of the Company's common stock was $23.67
per share, a decrease of $0.02 per share or 0.08% since December 31, 1996.
Return on average total common shareholders' equity was 7.8% and 11.8% for the
twelve months ended March 31, 1997 and 1996, respectively.

     The Company's ratio of earnings to fixed charges was 2.50 and 3.22 for the
twelve months ended March 31, 1997 and 1996, respectively.  The Company's ratio
of earnings to fixed charges and preferred stock dividends for the 1997 and
1996 twelve-month periods was 2.36 and 2.83, respectively.

     The decreases in residential and commercial sales reflect warmer winter
weather, and for the twelve-month period, cooler summer weather that more than
offset growth in the customer base.

     The increases in industrial sales reflect strong demand in the automotive
and construction sectors.

     The decreased sales to other customers reflect decreased demand from
wholesale for resale customers.

     Interconnection sales decreases reflect lower demand for energy and the
impact of the Fermi 2 outage.

FERMI 2 CAPACITY FACTOR PERFORMANCE STANDARD RESERVE

     Due to a repair and maintenance outage at Fermi 2 the capacity factor
performance standard reserve was increased by $24 million during the first
quarter of 1997.

     Fuel and purchased power expense decreased in the three-month period due
to the receipt of Fermi 2 business interruption insurance proceeds, lower net

offset by higher average unit costs resulting from increased usage of higher
cost purchased power replacing lower cost nuclear generation as a result of the
Fermi 2 outage.

     For the twelve-month period, fuel and purchased power expense increased
due to higher average unit costs resulting from increased usage of higher cost
purchased power replacing lower cost nuclear generation as a result of the
Fermi 2 outage,

increased coal contract buyout expense and a reduction in the receipt of Fermi
2 business interruption insurance proceeds, partially offset by lower net
system output and the steam heating special charge amortization.

OTHER OPERATION

Three Months

     Other operation expense increased primarily due to higher administrative
and general expenses ($7.6 million), non-regulated subsidiaries ($4 million)
and major storm ($2 million) expenses.

Twelve Months

     Other operation expense increased due primarily to higher sales expenses
($12.7 million), operating and development expense related to new computer
systems ($12 million), higher uncollectible customer accounts ($11.3 million)
and non-regulated subsidiaries ($10.4 million) expenses.  These expenses were
partially offset by lower incentive award expenses related to a shareholder
value improvement plan ($14.3 million), expenses recorded in the year-earlier
period in a reserve for the write-off of obsolete and excess stock material
($12 million) and the settlement of the Ludington Pumped Storage Plant fish
mortality case ($8.4 million).

MAINTENANCE

Three Months

     Maintenance expense decreased due to lower overhead and underground lines
support ($3 million), general property ($2.9 million) and transmission and
distribution ($2.2 million) expenses.  These decreases were partially offset by
higher major storm expenses ($3.7 million).

Twelve Months

     Maintenance expense increased due to higher overhead and underground lines
support ($14.7 million), nuclear plant ($5 million) and station maintenance
($4.1 million) expenses.  These increases were partially offset by lower
transmission and distribution ($6.2 million) and major storm ($3.3 million)
expenses.

STEAM HEATING SPECIAL CHARGES

     During the third quarter of 1996, following the completion of a review of
its steam heating operations, Detroit Edison recorded a special charge to net
income of $149.2 million.  The special charge included a reserve for steam
purchase commitments during the period 1997 through 2008 under the agreement
with the Detroit Resource Recovery Facility, and for expenditures in 1997 for
closure of a portion of the steam heating

                                       20



<PAGE>   21

system and improvements in service to remaining customers.  Beginning in 1997,
Detroit Edison recorded amortization of the reserve for steam purchase
commitments in fuel and purchased power expense.

DEPRECIATION AND AMORTIZATION

     Depreciation and amortization expense increased due primarily to increases
in plant in service, including internally developed software costs.

DEFERRED FERMI 2 AMORTIZATION

     Deferred Fermi 2 amortization, a non-cash item of income, was recorded
beginning with Detroit Edison's purchase of the Wolverine Power Supply
Cooperative, Inc.'s ownership interest in Fermi 2 in February 1990.  The annual
amount deferred decreases each year through 1999.

AMORTIZATION OF DEFERRED FERMI 2 DEPRECIATION AND RETURN

     Deferred Fermi 2 depreciation and return, non-cash items of income, were
recorded beginning with the implementation of the Fermi 2 rate phase-in plan in
January 1988.  The annual amounts of deferred depreciation and return decreased
each year through 1992.  Beginning in 1993 and continuing through 1998, these
deferred amounts will be amortized to operating expense as the cash recovery is
realized through revenues.

TAXES OTHER THAN INCOME TAXES

     Taxes other than income taxes increased due to higher MPSC assessment
fees, partially offset by lower payroll taxes.

INCOME TAXES

Three Months

     Income taxes decreased due to lower pretax income.

Twelve Months

     Income taxes decreased due to lower pretax income, partially offset by
changes in the prior years' federal income tax accrual and filed return
adjustments.

<PAGE>   22


OTHER INCOME AND DEDUCTIONS

OTHER INCOME AND (DEDUCTIONS) - NET

Three Months

     Other deductions increased due primarily to an increase in the write-off
of unamortized expenses related to the open market purchases of Mortgage Bonds
($1.6 million), an increase in expenses related to merchandising, jobbing and
contract work ($1.1 million), and higher legal expenses ($0.7 million).

Twelve Months

     Other deductions decreased due primarily to lower corporate contributions
($2.3 million), partially offset by an increase in promotional expenses ($1
million).

ACCRETION INCOME

     Accretion income, a non-cash item of income, was recorded beginning in
January 1988 to restore to income, over the period 1988-1998, losses recorded
due to discounting indirect disallowances of plant costs.  The annual amount of
accretion income recorded decreases each year through 1998.

ACCRETION EXPENSE

     Accretion expense, a non-cash item of expense, was recorded beginning in
January 1997 to charge to income, over the period 1997-2008, accretion of
interest expense resulting from the recording of the reserve for steam purchase
commitments at its present value at December 31, 1996, using a risk free
discount rate of 6.9%.

INTEREST CHARGES

LONG-TERM DEBT

     Long-term debt interest charges decreased due to the scheduled and early
redemption of Mortgage Bonds, partially offset by the issuance of QUIDS.

OTHER

     Other interest charges decreased due primarily to lower levels of
short-term borrowings.

PREFERRED STOCK DIVIDENDS OF DETROIT EDISON

Three Months

     Preferred stock dividends of Detroit Edison decreased due to the
redemption of Cumulative Preferred Stock, 7.68% Series, 7.45% Series and 7.36%
Series.

Twelve Months

     Preferred stock dividends of Detroit Edison decreased due to the
redemption of Cumulative Preferred Stock, 7.68% Series, 7.45% Series and 7.36%

for QUIDS and the conversion and redemption of Cumulative Preferred Stock 5.5%
Convertible Series.

LIQUIDITY AND CAPITAL RESOURCES

PRIVATE SECURITIES LITIGATION REFORM ACT -
FORWARD-LOOKING STATEMENTS

     Certain information presented in this Quarterly Report on Form 10-Q is
based upon 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, the impact
of newly-required FERC tariffs, actual sales and expenses, the effects of
competition, the implementation of utility restructuring in Michigan (which
involves pending regulatory proceedings, pending and proposed statutory
changes, and the recovery of stranded costs), environmental and nuclear
requirements and the success of non-utility projects.  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.

COMPETITION

THE DETROIT EDISON COMPANY

     MPSC.  The MPSC Staff Report on Electric Industry Restructuring was filed
in December 1996.  The Staff Report recognized that Michigan utilities should
have the opportunity to prepare for competition and be able to maintain their
financial health.

     In an order dated February 5, 1997, the MPSC requested that Detroit Edison
and Consumers Energy Company make informational filings with the MPSC to
disclose how they would propose to implement the Staff Report on Electric
Industry Restructuring.  The

                                       23



<PAGE>   24

filings were to include, among other items, detailed calculations of
anticipated stranded costs and transition charges.

     As discussed in the Company's Form 8-K, filed on March 13, 1997, Detroit
Edison filed its response with the MPSC on March 7, 1997 highlighting the
following points:

   -    Detroit Edison estimates the net after-tax present value of its
        stranded costs with reciprocity to be $5.4 billion.

   -    To mitigate the stranded costs, Detroit Edison proposed securitizing
        approximately $2.8 billion in assets, direct access phase-in
        totaling $1.4 billion, self-mitigation of $0.8 billion and a
        non-bypassable nuclear decommissioning surcharge of $0.4 billion.

   -    Implementing securitization will result in an annual net rate decrease 
        for all customers totaling $295 million.

   -    Transition charges would only be assessed to customers leaving the
        system.

   -    Endorsement of a bidding program to allocate capacity between
        customers interested in direct access.

   -    Deregulation of electric markets will result in financial
        uncertainty and risk to the shareholders of the Company.  Detroit
        Edison will bear the risk of full replacement of electricity sales lost
        to retail wheeling, plus approximately an additional $800 million in
        mitigation responsibility which should be in place during the 2001-2004
        time period, and which Detroit Edison anticipates will be achieved
        largely through reductions in operating and maintenance expenses.

     The MPSC has held public hearings on the informational filings and has
received additional written comments.

CASH GENERATION AND CASH REQUIREMENTS

CONSOLIDATED STATEMENT OF CASH FLOWS (UNAUDITED)

     Net cash from operating activities decreased due primarily to lower net
income before non-cash charges and changes in current assets and liabilities.

     Net cash used for investing activities was lower in the three-month
period, due to decreased plant and equipment expenditures.  Net cash used for
financing activities was higher in the twelve-month period due primarily to
increased non-regulated plant and equipment expenditures.

     Net cash used for financing activities was lower in the three-month period
due primarily to a decrease in funds used to reduce short-term borrowings and
Detroit Edison's cash portion of a restructuring dividend to the Company in the
prior period. Net

                                       24

cash used for financing activities was higher in the twelve-month period due
primarily to higher redemption of long-term debt.

ADDITIONAL INFORMATION

     During the period January through April 28, 1997, Detroit Edison purchased
a total of $40.5 million of Mortgage Bonds on the open market, consisting of
$19 million of 7.74% 1993 Series J, $7 million of 7.81% 1993 Series E, $4.5
million of 7.78% 1993 Series E and $10 million of 7.79% 1993 Series E.  These
bonds have been canceled.

     Detroit Edison's 1997 cash requirements for its capital expenditure
program are estimated at $448 million, of which $86 million had been expended
as of March 31, 1997.  Internal cash generation is expected to be sufficient to
meet its cash requirements for capital expenditures as well as scheduled
long-term debt redemptions.

     Detroit Edison had short-term credit arrangements of approximately $464
million at March 31, 1997, under which $4 million of borrowings were
outstanding.

NON-REGULATED INVESTMENTS

     Cash requirements for non-regulated investments are estimated to range
from $300 to $350 million in 1997, of which $6 million had been expended as of
March 31, 1997.  Non-regulated investments are expected to be substantially
externally financed.

CAPITALIZATION

     The Company's capital structure as of March 31, 1997 was 46.9% common
shareholders' equity, 2.0% cumulative preferred stock of subsidiary and 51.1%
long-term debt (which includes 3.2% of QUIDS) as compared to 46.7%, 2.0% and
51.3%, respectively, at December 31, 1996.

OTHER

     In 1997 the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, "Earnings per Share."  The Company does
not expect the application of this statement to have a material impact on its
financial position, liquidity or results of operations.

                          PART II - OTHER INFORMATION

ITEM 1 - LEGAL PROCEEDINGS.

     A former Detroit Edison employee has filed a lawsuit in the U.S. District
Court for the Southern District of Michigan alleging that Detroit Edison
engaged in age discrimination and procedural violations of the Federal Age
Discrimination in Employment Act of 1967.   In the lawsuit, (Frazier,
individually and on behalf of all similarly situated Detroit Edison voluntary
separation offer recipients v Detroit Edison) plaintiff seeks to represent a
group of individuals who accepted voluntary separation offers from Detroit
Edison.  Detroit Edison is of the opinion that the allegations of the lawsuit
are without merit.

     For information on further legal proceedings, see Note 3 herein.

ITEM 5 - OTHER INFORMATION.

     The Company, through its non-regulated subsidiary Edison Energy Services,
Inc., has reached a tentative agreement to acquire the coke oven battery and
related assets in River Rouge, Michigan from National Steel Corporation
("NSC").  NSC will continue to operate and maintain the facility under contract
with the Company.  A majority of the coke production will be dedicated to
meeting NSC's requirements under a twelve year supply agreement.  The
acquisition is expected to provide gross revenues between $100 and $150 million
per year.  The acquisition is subject to the Company and NSC reaching final
agreement on all aspects of the transaction, as well as regulatory review and
approval of both companies' boards of directors.

                            EXECUTIVE INCENTIVE PLAN
                           EFFECTIVE JANUARY 27, 1997




OVERVIEW
- --------

The Executive Incentive Plan ("Plan") supplements possible annual financial
incentives provided under the Shareholder Value Improvement Plan - A for
eligible members of Detroit Edison Company's ("Company") senior management.  It
rewards such employees for the accomplishment of financial and strategic
objectives that improve DTE Energy Company's ("DTE") operating results and
positions DTE for long term profitability.  Recipients of Plan awards may,
under specified conditions, defer the payment of awards.

The Plan measures calendar year performance.  The current year's targets,
measures and weights  will be communicated annually following approval.


ADMINISTRATION
- --------------

The Organization and Compensation Committee ("Committee") of the Detroit Edison
Board of Directors ("Board of Directors") is Plan Administrator with
responsibility for the administration of the Plan.  The Committee has the
authority to interpret the provisions of the Plan and prescribe any regulations
relating to its administration.  The decisions of the Committee with respect
thereto shall be conclusive.

The Committee, on an annual basis, will review and, if appropriate, recommend
to the Board of Directors for approval, the specific criteria for eligibility,
the type and timing of awards and the manner of payment of awards (current
and/or deferred), the performance measures and related weights to be used in
computing award amounts and  amounts in the Performance Fund, as defined
herein,  and the performance levels for each performance measure.  The Board of
Directors  reserves the right to amend, suspend or terminate the Plan at any
time (See "Awards").

Current awards calculated under the terms of the Plan are not payable until
such time as the Board of Directors' approval has been granted.  The Board of
Directors reserves the right to reduce or cancel any awards that might
otherwise be made if, in its sole discretion, it determines that the
performance achieved is not indicative of an improvement in DTE's overall
performance.  If such a determination is made, the Plan may be canceled or
substantially modified with the result of terminating or decreasing any awards
that might otherwise be made hereunder.

The Treasurer will be responsible for making award payments, for establishing
and maintaining the deferred accounts for award recipients, and for maintaining
all necessary records regarding the valuation and payment of awards.



<PAGE>   3


The Vice President-Human Resources will assist the Committee in the
development, administration and communication of the Plan.

ELIGIBILITY
- -----------

Any person who is elected to the position of Vice President and above at
Detroit Edison (i.e., senior management) and who holds and actively performs in
one or more such eligible positions for a total of at least seven months during
the Plan year will become eligible to participate in the Plan.  "Hold and
actively perform" excludes all temporary assignments.  Any key employee of
Detroit Edison may be designated by the Committee to become a participant in
the Plan.  Participants' performance must be considered at least satisfactory
or equivalent for the applicable calendar year to be eligible to receive an
award under the Plan.

Employees of the Company are not eligible to participate in the Plan if they
are eligible to participate in any other Company incentive program other than
the Long Term Incentive Plan and the Shareholder Value Improvement Plan - A.

Exceptions to the eligibility criteria may be authorized by the Board of
Directors.

Participation in the Plan does not guarantee continued employment with the
Company.

PLAN YEAR
- ---------
The Plan year will be a calendar year.

AWARD OPPORTUNITY
- -----------------
Awards, if any, will be payable from a fund ("Performance Fund") established by
multiplying the base salary (including applicable amounts deferred under
Company-sponsored benefit plans) of each otherwise eligible participant as of
the last day of the payroll year by a target percent of salary by position and
then by a percent based upon the achievement of specific performance measures
and combining such individual amounts into one collective fund.

PERFORMANCE MEASURES, LEVELS AND WEIGHTS
- ----------------------------------------
The target percentages, measures of performance and weights applicable to each
Plan year will be communicated annually to all eligible employees.




AWARDS
- ------


                                      2



<PAGE>   4




Award amounts will be payable from the Performance Fund and will be granted, in
the sole discretion of the Board of Directors, to otherwise eligible
participants, in such amounts, if any, as are determined to be appropriate by
the Board of Directors.

Awards under the Plan are not considered basic compensation for purposes of the
Company's qualified and non-qualified savings plans, the Company's qualified
and non-qualified retirement plans, insurance or any other Company-sponsored
qualified or non-qualified employee benefit programs.

AWARD PAYMENT
- -------------
No awards will be paid under this Plan if no awards are paid under the
Shareholder Value Improvement Plan - A regardless of whether other terms and
conditions are met.

Annual awards, if any, will be paid as soon as practicable following approval
by the Board of Directors unless deferred as permitted herein.

Eligible participants will be permitted to defer the payment of 50% to 100% of
an approved award for a period of from one to five years ("Deferred Awards").
A Deferred Award Account will be established for each award recipient with a
timely Deferral Notice on file with the Company.  For the calendar year during
which this Plan is adopted, deferrals must be irrevocably submitted within 30
calendar days of the date of adoption.  Thereafter, deferrals must be
irrevocably submitted prior to the commencement of the Plan year during which
the services giving rise to the award will be performed on a form ("Deferral
Notice") to be furnished by the Company.  For example, a Deferral Notice for an
award to be based on 1998 performance must be filed with the Company by the end
of 1997.  Once filed with the Company, the Deferral Notice may not be changed
or revoked.

DEFERRED AWARD ACCOUNTS
- -----------------------
Deferred Award Accounts will be established for each recipient with a timely
Deferral Notice on file as soon as practicable following the Board of
Directors' approval of an award.  Amounts in Deferred Award accounts will be
deemed to earn interest at a rate calculated on the last business day of each
month (commencing with the first month following the deferral of an award) with
reference to the Five-Year United States Treasury Bond rate, as reported in a
nationally-recognized financial service.

Deferred Awards, including deemed earnings thereon, will be payable as soon as
practicable in the calendar year selected by an award recipient in the Deferral
Notice.  In the event that a participant with a Deferred Account dies, retires
or terminates employment with the Company and its Affiliates prior to the time
established for payment in the Deferral Notice, such participant's      
Deferred Account, plus earnings thereon, shall be paid to such participant or
participant's designated beneficiary as soon as possible thereafter.  For
purposes of the Plan, the term "Affiliate" shall mean any parent of the Company
or any entity in which the Company or any parent of the Company directly or
indirectly beneficially owns more than 50% of the voting securities.



                                      3



<PAGE>   5


The Committee may, in its discretion, terminate any Deferral and immediately
pay out such award in cash.

FORFEITURE
- ----------
Otherwise eligible participants who are discharged or resign from the Company
and its Affiliates prior to the end of the Plan Year (December 31) will forfeit
an annual award unless the termination is the result of disability (where
disability is defined as being eligible to receive a benefit under a long-term
disability plan of the Company or an Affiliate), death or retirement (where
retirement is defined as a resignation at age 55 or older and with at least 10
years of service with the Company and its Affiliates or at age 65 or older).

Deferred Accounts are not subject to forfeiture.

FUNDING STATUS
- --------------
Benefits under the Plan, including any  Deferred Accounts, are payable solely
from the general assets of the Company and shall remain unfunded and unsecured
(under federal income tax laws and Title I of the Employee Retirement Income
Security Act of 1974, as amended) during the entire period of the Plan's
existence.  The participant, the participant's spouse or beneficiary are merely
general creditors of the Company and the obligations of the Company hereunder
are purely contractual and shall not be funded or secured in any way.

NON-ALIENABILITY AND NON-TRANSFERABILITY
- ----------------------------------------
The right of a participant and participant's spouse or beneficiary to payment
of any benefit or deferred compensation hereunder shall not be alienated,
assigned, transferred, pledged or encumbered and shall not be subject to
execution, attachment or similar process.  No participant may borrow against
the deferred account established for his or her benefit hereunder.  No account
shall be subject in any manner to alienation, sale, transfer, assignment,
pledge, encumbrance, charge, garnishment, execution or levy of any kind,
whether voluntary or involuntary, including but not limited to any liability
which is for alimony or other payments for the support of a spouse or former
spouse, or for any other relative of any employee.  Any attempted assignment,
pledge, levy or similar process shall be null and void and without effect.




BENEFICIARY DESIGNATION
- -----------------------

Each eligible participant may name any beneficiary to whom awards under the
Plan are to be paid in case of the eligible participant's death.  Each
designation will revoke all prior designations by the 
                                      4

eligible participant and shall be on a form prescribed by the Plan 
Administrator and will be effective only when filed by the eligible participant 
with the Treasurer.  In the absence of any such designation, awards due shall 
be paid to the participant's (1) life insurance beneficiary designated by the 
participant with respect to life insurance maintained by the Company for the 
benefit of the participant, or, in the absence of a designated life insurance 
beneficiary, (2) to the participant's estate.

GOVERNING LAW
- -------------

The Plan shall be governed by the laws of the State of Michigan and, to the
extent that may be applicable, the Federal laws of the United States.

Development of New Businesses

- -    Establish a power marketing subsidiary (personnel, systems/procedures,
     strategy, etc.) by year end having progressed significantly towards having
     this subsidiary recognized as an important emerging major player in our
     region.

- -    Establish a coal marketing/trading subsidiary - both the personnel and the
     strategy - by year end and take important first steps toward establishing
     DTE as a major national player in coal marketing, trading, transportation,
     and services.

- -    Establish a natural gas marketing capability within CEB that complements
     our electric power marketing initiative.  The organization (likely in
     concert with MCN) and strategy should be in place and we should be
     recognized by year end as an important emerging electric/gas provider in
     the Great Lakes region.

- -    Make substantial progress on the strategy for DTE's generating assets and
     marry this strategy with DTE's coal marketing strategy.  This effort will
     likely involve work with specialty consulting firms as well as numberous
     discussions with potential partners.  This strategy should also deal with
     market power issues that emerge from the record discussions.

- -    Establish Edison America as our unregulated mass market electric, gas and
     communications marketing subsidiary, with the business plan completed and
     accepted in the second quarter and by year end have the subsidiary as a
     major player in the unregulated Michigan market and taking the first steps
     in being a player in the emerging regional/national market.
