               ANNUAL REPORT ON FORM 10-K FOR DTE ENERGY COMPANY
                                     PART I

ITEMS 1 AND 2 - BUSINESS AND PROPERTIES.

GENERAL

     DTE Energy Company, a Michigan corporation incorporated in 1995, is an
exempt holding company under the Public Utility Holding Company Act.  On
January 1, 1996, the holders of Detroit Edison's common stock exchanged such
stock on a share-for-share basis for the common stock of the Company.  Also on
January 1, 1996, Detroit Edison declared a dividend to the Company in the form
of the stock of five subsidiaries:  DE Energy Services, Inc., DTE Capital
Corporation, Edison Development Corporation, Syndeco Realty Corporation and UTS
Systems, Inc.  As a result of this corporate restructuring, DTE Energy became
the parent holding company of Detroit Edison and the five previously
wholly-owned Detroit Edison subsidiaries.  During 1996, the Company established
two additional non-regulated subsidiaries:  DTE Edison America, Inc., and Huron
Energy Services, Inc.  The new holding company structure is designed to provide
financial flexibility for the development of new businesses, many of which are
expected to be energy-related.  It is also a mechanism for separating the
regulated utility business of Detroit Edison from non-regulated businesses,
thereby protecting the utility business from the potential risks of non-utility
operations.

     The Company has no significant operations of its own.  Detroit Edison is
the Company's principal operating subsidiary, representing approximately 98.7%
of the Company's assets at December 31, 1996.  Certain of the Company's
wholly-owned subsidiaries and affiliates are engaged in non-regulated
energy-related businesses, with other projects still in the formative stages.

NON-REGULATED OPERATIONS

     Six wholly-owned subsidiaries, along with various affiliates, of the
Company are engaged in non-regulated  businesses, including energy-related
services.  Such services include the operation of landfill gas-to-energy
facilities, providing expertise in the application of new energy technologies,
real estate development, power marketing, specialty engineering services and
retail marketing of energy, communications and other convenience products.  A
seventh wholly owned subsidiary, DTE Capital Corporation, provides financial
services to the Company's non-regulated subsidiaries.

     At February 28, 1997, DTE Capital Corporation had a $200 million Revolving
Credit Agreement, backed by a Support Agreement from the Company, under which
no borrowings were outstanding.

     Cash requirements for non-regulated investments and capital expenditures
in 1996, 1995 and 1994 were $60 million, $8 million and $15 million,
respectively, and are 



                                       6
<PAGE>   9

estimated to range from $300 million to $350 million in 1997.  Non-regulated
investments and capital expenditures are expected to be externally financed.

UTILITY OPERATIONS

     Detroit Edison, incorporated in Michigan since 1967, is a regulated public
utility engaged in the generation, purchase, transmission, distribution and
sale of electric energy in a 7,600 square mile area in Southeastern Michigan.
Detroit Edison's service area includes about 13% of Michigan's total land area
and about half of its population (approximately five million people).  Detroit
Edison's residential customers reside in urban and rural areas, including an
extensive shoreline along the Great Lakes and connecting waters.  See operating
revenues, sales and customer data by rate class below.

     Detroit Edison generally experiences its peak load and highest total
system sales during the third quarter of the year as a result of air
conditioning and cooling-related loads.  In 1996 a new all-time peak of 10,337
MW was reached in August.  See "Properties".

     CERTAIN FACTORS AFFECTING PUBLIC UTILITIES

     The electric utility industry is facing serious issues as legislators and
regulators consider various proposals designed to reduce rates and promote
economic growth through competition.  Municipalization, deregulation,
cogeneration, independent power production, open access to transmission lines,
competitive bulk power supply markets and the unbundling of utility products
and services are issues under consideration.

     Detroit Edison is participating at both the Federal and state (Michigan)
levels in legislative and administrative proceedings attempting to make the
electric energy market competitive.  These proceedings are dealing with the
effects of competition on both public utilities and consumers.  Issues under
consideration include:  (1) the recovery of stranded costs by public utilities
now recovering capital costs under traditional ratemaking principles, (2)
retail wheeling and open transmission access, and (3) revisions to (and the
possible repeal of all or portions of) various federal and state energy-related
statutes.

     The December 19, 1996 MPSC Staff Report on Electric Industry
Restructuring, if adopted by the MPSC and Michigan legislature as proposed,
would alter the regulatory process in Michigan and provide for a transition to
competition for the non-nuclear generation segment of Detroit Edison's
business.  The Staff Report being considered provides for the recovery of
regulatory assets, capital costs of Fermi 2 and costs incurred to implement the
transition to competition.  Also, if the Staff Report in its present form is
adopted, the non-nuclear generation segment of Detroit Edison's business would
not qualify for SFAS No. 71, "Accounting for the Effects of Certain Types of
Regulation", accounting following the transition period.  However, Detroit
Edison believes that the nuclear generation and transmission and distribution
segments of its business will continue to be regulated and qualify under the
accounting model prescribed by SFAS No. 71.

     In addition, Detroit Edison, in common with other domestic public
utilities, is subject to extensive environmental regulation.  Additional costs
may result as the effects of various chemicals on the environment (including
nuclear waste) are studied and governmental regulations are developed and
implemented.  The costs of future nuclear decommissioning activities are the
subject of increased regulatory attention.

     See Notes 1, 2 and 3, Item 7 - Management's Discussion and Analysis of
Financial Condition and Results of Operations - Liquidity and Capital Resources
and "Regulation and Rates" herein.

     CAPITAL EXPENDITURE PROGRAM - DETROIT EDISON

     Detroit Edison has no current plans to construct additional generating 
plants.  Capital expenditures in 1996, 1995 and 1994 were $479 million
(including $5 million of AFUDC), $444 million (including $4 million of AFUDC)
and $365 million (including $4 million of AFUDC), respectively.  Also, the
purchase of leased equipment totaled $11.5 million in 1994.




                                      9
<PAGE>   12
     Projections for the 1997-2001 period contemplate capital expenditures of
approximately $2.2 billion (including an estimated $15 million of AFUDC).  The
1997 capital expenditure program is budgeted at $451 million (including $3
million of AFUDC).  The 1997 capital expenditure program includes planned
expenditures for production plant improvement projects ($93 million),
transmission and distribution facilities ($285 million), and general plant and
miscellaneous construction projects ($73 million).

     FINANCING

     COMPANY.  Apart from the Board of Directors' approval, the Company is not
required to obtain regulatory approval for the issuance of debt.

     At December 31, 1996, the book value of the Company's common stock was
$23.69 per share as compared to $23.62 per share at December 31, 1995.

     DETROIT EDISON.  Orders of the MPSC permit Detroit Edison to issue
approximately $2.03 billion of securities for the purpose of refinancing
taxable debt and equity and to replace funds used for those purposes.   Detroit
Edison also has MPSC authority to refinance a substantial portion of its
non-taxable debt obligations.

     Detroit Edison has an effective Shelf Registration Statement on file with
the SEC pursuant to which it may issue up to $165 million in debt securities.

     Outstanding FERC orders authorize Detroit Edison to issue up to $1 billion
of short-term debt through May 31, 1999.  At February 28, 1997, Detroit Edison
had short-term credit arrangements of $464 million under which no borrowings
were outstanding.

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

     See Notes 5, 7, 8, and 9 and also see Item 7 - Management's Discussion and
Analysis of Financial Condition and Results of Operations - Liquidity and
Capital Resources for information on Detroit Edison's 1996 issuance of $185
million of Quarterly Income Debt Securities, the redemption of Cumulative
Preferred Stock totaling $185 million and the open market purchases of $56.5
million of Mortgage Bonds.  From time to time, when economic, Detroit Edison
repurchases debt securities on the open market.

     During the period January through March 24, 1997, Detroit Edison purchased
a total of $21 million of Mortgage Bonds on the open market, consisting of $14
million of 7.74% 1993 Series J and $7 million of 7.81% 1993 Series E.  These
Mortgage Bonds have been cancelled.

     The four Monroe units, two Belle River units, Fermi 2 and one unit at each 
of the Trenton Channel and St. Clair Power Plants account for 5,852 MW of
Detroit Edison's summer net rated capability.  These units, which commenced
commercial operation during the period 1968 through 1988, are Detroit Edison's
larger, more efficient generating units.  The Monroe, Belle River, St. Clair,
and Fermi 2 Power Plants provided approximately 42%, 16%, 16%, and 10%
respectively, of Detroit Edison's total 1996 power plant generation.

     Detroit Edison and Consumers are parties to an Electric Coordination
Agreement providing for emergency assistance, coordination of operations and
planning for bulk power supply, with energy interchanged at nine
interconnections.  Detroit Edison and Consumers also have interchange
agreements to exchange electric energy through 12 interconnections with The
Toledo Edison Company, Indiana Michigan Power Company, Northern Indiana Public
Service Company and Ontario Hydro.  In addition, Detroit Edison has interchange
agreements for the exchange of electric energy with Michigan South Central
Power Agency, Rouge Steel Company and the City of Wyandotte.

     Detroit Edison also purchases energy from cogeneration facilities and
other small power producers.  Energy purchased from cogeneration facilities and
small power producers amounted to $28.3 million, $20.6 million and $16.7
million for 1996, 1995 and 1994, respectively, and is currently estimated at
$41 million for 1997.

     An all time peak demand of 10,337 MW was experienced for Detroit Edison's
system on August 7, 1996.  The new peak was served using a combination of
installed generation, long-term purchases and seasonal capacity purchases.
Previous peaks were 10,049 MW set in August 1995 and 9,878 MW set in June 1995.
Based on the current load forecast and planned generating capability, Detroit
Edison estimates that its summer reserve margin, expressed as a percentage of
peak demand, will be approximately 12% for 1997 and 1998.  Included as part of
the 1997 and 1998 reserve margin projections are Detroit Edison's present and
projected capacity purchases and anticipated peak reductions due to the
implementation of various DSM programs, including the R-10 interruptible rate.
The 1997 and 1998 reserve margins meet Detroit Edison's current planning
criterion, which specifies a minimum reserve margin of 12%.

     Detroit Edison's electric generating plants are interconnected by a
transmission system operating at up to 345 kilovolts through 94 transmission
stations.  As of December 31, 1996, electric energy was being distributed in
Detroit Edison's service area through 582 substations over 2,996 distribution
circuits.

     COAL.  Detroit Edison estimates that it will require approximately 600
million tons of coal over the next 35 years for its coal-fueled generating
units.  Detroit Edison expects to obtain a significant portion of its
requirements through long-term contracts and the balance through short-term
agreements and spot purchases.  Detroit Edison has contracts with five coal
suppliers for a total purchase of up to 79 million tons of low-sulfur western
coal to be delivered during the period from 1997 through 2005.  It also has
several contracts for the purchase of approximately 8 million tons of
Appalachian coal with varying contract expiration dates through 1999.  These
existing long-term coal contracts include provisions for market price reopeners
and price escalation as well as de-escalation.

     The low-sulfur western coal contracts have a maximum sulfur content of
0.55%.  The Appalachian coal contracts range in maximum sulfur content from
0.80% to 3.5%.  As required by the Michigan Air Pollution Control Commission,
Detroit Edison's aggregate consumption of both types of coal averages below 1%
sulfur content.

     For further information on environmental matters, see "Environmental
Matters" and Item 7 - Management's Discussion and Analysis of Financial
Condition and Results of Operations.

     OIL.  Detroit Edison purchases No. 2 oil, used principally for peaking
units and start-up for other units, and No. 6 oil, used principally by
Greenwood Unit No. 1, through short-term agreements and spot market purchases.

     GAS.  Natural gas is used principally at one of Detroit Edison's steam
heating plants and Greenwood Unit No. 1.  Natural gas requirements are met
through short-term agreements and spot market purchases.

     NUCLEAR.  Renaissance holds title to the nuclear fuel utilized at Fermi 2.
Under the terms of a heat purchase contract between Detroit Edison and
Renaissance, Detroit Edison makes quarterly payments to Renaissance for the
cost of the nuclear fuel

                                      13
<PAGE>   16
consumed and interest expense.  For information on nuclear fuel financing, see
Notes 9 and 10.

     Detroit Edison has sufficient supplies to meet 1998 Fermi 2 plant
refueling requirements.  Also, Detroit Edison believes that adequate uranium
supplies exist to supplement existing contracts to meet plant requirements
beyond 1998.  Detroit Edison has a contract with the DOE for the future storage
and disposal of spent nuclear fuel from Fermi 2.  Under the terms of the
contract, Detroit Edison makes quarterly payments to the DOE based upon a fee
of 1 mill per kWh applied to the Fermi 2 electricity generated and sold.  Fees
levied for 1996 totaled $4 million.  The spent nuclear fuel disposal cost is
included as a component of Detroit Edison's nuclear fuel expense.  The Federal
Nuclear Waste Policy Act of 1982 provides that in return for this fee the DOE
is to provide a permanent repository for spent nuclear fuel by January 31, 1998
which statutory obligation was upheld in October 1996 by the United States
Court of Appeals for the District of Columbia Circuit.  Nevertheless, the DOE
has indicated it will be unable to begin acceptance by the required date and
has requested comments from Detroit Edison and other affected companies.  The
DOE and utilities with nuclear units are pursuing other interim storage
options.  Detroit Edison estimates that existing temporary storage capacity at
Fermi 2 will be sufficient until the year 2001, or until 2017 with the
expansion of such storage capacity.

     On January 31, 1997, Detroit Edison and 35 other utilities filed suit
against the DOE in the United States Court of Appeals for the District of
Columbia Circuit, seeking authorization to escrow payments into the Nuclear
Waste Fund because of the DOE's anticipated failure to meet its obligation to
begin taking high level waste and spent nuclear fuel by January 31, 1998.  A
companion lawsuit seeking the same relief was filed by 46 states or state
agencies on the same date.  The MPSC has issued an order commencing an inquiry
concerning the continuing collection from ratepayers of monies to pay into the
Nuclear Waste Fund.

 REGULATION AND RATES

     MICHIGAN PUBLIC SERVICE COMMISSION.  Detroit Edison is subject to the
general regulatory jurisdiction of the MPSC, which, from time to time, issues
its orders pertaining to Detroit Edison's conditions of service, rates and
recovery of certain costs, accounting and various other matters.

     As discussed below and in "Certain Factors Affecting Public Utilities"
herein and Item 7 - Management's Discussion and Analysis of Financial Condition
and Results of Operations, a restructuring of utility regulation is currently
under consideration in Michigan.  While all orders and proceedings discussed
below are presently in effect, approval and implementation of a statutory
restructuring may result in substantial changes to, if not reversal of, these
orders and possible termination of the proceedings.


                                      14
<PAGE>   17

     MPSC orders issued in December 1988 and on January 21, 1994 are currently
in effect with respect to Detroit Edison's rates and certain other revenue and
operating-related matters.

     On January 21, 1994, the MPSC issued an order reducing Detroit Edison's
rates in the amount of $78 million annually.  The order was appealed before the
Michigan Court of Appeals, which issued a favorable opinion on February 7,
1997.  The Court's decision is now the subject of a motion for rehearing.  See
Note 3 for a discussion of the provisions of the January 21, 1994 order.

     For information on the MPSC Staff Report on Electric Industry
Restructuring, see Note 1 and Item 7 - Management's Discussion and Analysis of
Financial Condition and Results of Operations.

     In an order dated February 5, 1997, the MPSC requested that Detroit Edison
and Consumers make informational filings with the MPSC to disclose how they
would propose to implement the Staff Report on Electric Industry Restructuring.
The filings were to include, among other items, detailed calculations of
anticipated stranded costs and transition changes.

     On March 7, 1997, Detroit Edison filed its response with the MPSC.
Detroit Edison continues to support its position that direct access must be
coupled with the opportunity to recover stranded costs.  In addition, Detroit
Edison indicated its support of restructuring contemplates the completion of
all regulatory and legislative proceedings by December 31, 1997.

     In its filing, Detroit Edison establishes that neither available
transmission capacity nor market power concerns are real barriers to
implementation of the MPSC Staff's plan, especially during the 1997 - 2000
retail direct access phase-in period.  Detroit Edison is a staunch advocate for
prompt development of a Michigan ISO and is fully engaged in the work being
carried on by 25 utilities in 10 states to develop a Midwest ISO.  Detroit
Edison has set a goal internally for the formation of a Michigan based ISO by
June 1, 1998.

     Using the MPSC Staff Report definition of stranded costs, and assuming
that all customers have direct access on January 1, 1997, Detroit Edison
estimates the net after-tax present value of its stranded costs with
reciprocity to be $5.4 billion.  This value assumes that Detroit Edison can
successfully remarket lost sales at the prevailing  market clearing price.
Without this mitigation, stranded costs without reciprocity would increase
significantly.  The MPSC Staff's reciprocity requirement makes this mitigation
reasonable.  Under the MPSC Staff's plan, the estimated $5.4 billion of
stranded costs will be recovered through a combination of securitization and
transition surcharges, Detroit Edison mitigation, and the adoption of an
appropriate phase-in of direct access.  All of these mechanisms operate in a
manner that does not shift any costs to non-participants.  Furthermore, the
securitization feature using rate reduction bonds has been designed to deliver
immediate rate decreases to all customers.

                                      15
<PAGE>   18
     The components for the mitigation or the recovery of the estimated $5.4
billion of stranded costs are:  nuclear decommissioning non-bypassable
surcharge $0.4 billion, securitization $2.4 billion, direct access phase-in
$1.4 billion, competitive transition surcharge $0.4 billion and self-mitigation
$0.8 billion.

     Detroit Edison proposes to securitize approximately $2.8 billion in
assets.  These assets will consist of $2 billion for Fermi 2 plant assets, $0.4
billion for regulatory assets and $0.4 billion for purchased power contracts
from qualifying facilities.  The $2.8 billion securitization results in a
reduction of strandedness of $2.4 billion because the securitized amount
includes cost items which are not included in the stranded cost calculation or
Detroit Edison's balance sheet.

     Implementing securitization will result in a net rate decrease for all
customers totaling approximately $295 million.  The Company anticipates that
the rate reduction bonds would be 15-year AAA rated with a coupon rate of 7.5%.

     During the transition period for each major customer group, utility
generation costs will be frozen at 1996 levels.  The transition period for
industrial and large commercial customers served at primary voltage will end on
January 1, 2001 and for small commercial and residential customers on January
1, 2004.  Detroit Edison's filing maintained that such safeguards are needed
for customers during the industry's move to a competitive market.  The freeze
will provide price stability for customers who remain on the utility's system
during the transition period.

     In the filing, Detroit Edison recommended that transition charges only be
assessed to customers leaving the utility system.  Those who remain Detroit
Edison customers will be protected from cost shifting.  Transition charges,
efforts to increase sales and operating efficiencies, and adoption of an
appropriate phase-in of direct access will prevent cost shifting and are part
of the stranded cost recovery process.

     Both the MPSC Staff Report and Detroit Edison endorse a bidding program to
allocate capacity between customers interested in direct access, with the basic
presumption being that the program will be oversubscribed during the phase-in
period.  An example of capacity allocations of 225 MW would be:  residential 85
MW, small business 55 MW, large non-manufacturing 35 MW and industrial 50 MW.

     In its filing, Detroit Edison acknowledged that the 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 largely 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.


                                      16
<PAGE>   19
     The MPSC will hold four public hearings on the informational filings on
March 25, March 26, April 2, and April 3, 1997, and will receive additional
written comments by April 7, 1997.

     On March 30, 1995, Detroit Edison submitted its 1994 PSCR reconciliation
filing with the MPSC.  On December 7, 1995, the MPSC approved a partial
settlement agreement resolving most of the issues regarding the 1994 PSCR
reconciliation and the Fermi 2 capacity factor performance standard
disallowance for 1994.  A January 1996 refund of $7.7 million plus interest was
made to PSCR customers.  Also, Interruptible Supply Rider (R-10) customers
received a refund of $2.6 million.  This partial settlement is intended to hold
customers harmless from the effects of the December 1993 turbine-generator
failure at Fermi 2.  A final MPSC order was issued on April 10, 1996 which
resolved all outstanding contested issues. As a result of the order, no
additional refunds to customers will be required.

     In March, 1996, Detroit Edison requested the MPSC to carry its 1995 PSCR
reconciliation case under-recovery of approximately $14.8 million forward to
its 1996 PSCR reconciliation.  In a December 1996 PFD, an ALJ recommended a
$9.5 million disallowance of Fermi 2 nuclear fuel expense due to operations of
the plant in 1995 at a reduced power output.  Detroit Edison and the MPSC Staff
believe the appropriate disallowance to be approximately $8 million.  Detroit
Edison awaits an order of the MPSC.  See Note 3.

     On April 26, 1996, an MPSC ALJ issued his PFD in the Detroit Edison PSCR
Plan for 1996.  The ALJ adopted the adjustment proposed by the Michigan
Attorney General to reduce 1996 PSCR expenses by $8.3 million because of lost
fuel efficiency at Fermi 2 caused by the unit operating at a reduced power
output until the installation of major turbine components during a scheduled
refueling and maintenance outage that commenced in September 1996.  In
September, 1996, the MPSC approved Detroit Edison's request for the PSCR
billing factor for 1996 and deferred consideration of the adjustment proposed
by the Michigan Attorney General until the 1996 PSCR reconciliation.  See Note
3.

     On September 30, 1996, Detroit Edison filed its PSCR plan recommending a
fuel adjustment for bills rendered in 1997.  Fuel and purchased power costs are
expected to decrease 10.6%, on average, in 1997 over the corresponding forecast
for 1996.

     Conservation and Demand-Side Management Programs - As the result of a
generic review of Michigan conservation programs, the MPSC in June 1988 ordered
each Michigan gas and electric utility to file a biennial energy conservation
report, including a three-year plan.  Detroit Edison continues to operate
programs in compliance with the generic order and the more recent order on
January 21, 1994.

     On April 11, 1994, the MPSC issued an order approving a partial settlement
agreement covering Detroit Edison's energy conservation programs for the period
1994-1996.  The order authorized Detroit Edison to collect $21.2 million
through a surcharge for 


                                      17
<PAGE>   20
the three-year program to install energy conservation measures in
low-income customer households.  The MPSC, at Detroit Edison's request,
approved the elimination of the surcharge in an order dated August 22, 1996.

     Also, a January 21, 1994 MPSC order authorized a three-year DSM program.
Detroit Edison collected approximately $7 million for the 1994 DSM program.  In
1995, a reduced DSM surcharge and programs totaling $4.9 million in 1995, was
approved by the MPSC.  The MPSC has approved Detroit Edison's $4 million 1996
DSM plan which was a customer-focused demand reduction program that lowered
customer rates and eliminated the customer surcharge for the plan.

     Detroit Edison's fourth MPSC approved biennial plan for 1997 and beyond
anticipates spending in 1997 (and 1998, if necessary) the remaining funds
collected for its 1994-1996 energy conservation programs.

     Integrated Resource Plan - Detroit Edison's IRP is designed to provide
resource plans which have adequate flexibility to react to major changes and at
the same time address the concerns of its customers.  It attempts to minimize
risks and costs to customers and shareholders alike, while maintaining an
appropriate balance between demand-side and supply-side alternatives.  Detroit
Edison's first IRP proposed to meet future load requirements by utilizing
existing power plant units that are in economy reserve status rather than
building new plants.

     On September 1, 1994, Detroit Edison filed its biennial third IRP with the
MPSC.  This IRP, which covered a 15-year (1994-2008) study period, called for
the return to service of existing plant and a DSM program that will continue to
provide for interruptible service to large primary customers which is expected
to reduce peak demand by 500 MW.  The recommended IRP indicated that the
restart of the Conners Creek coal-fired units that are currently in economy
reserve is the most economic supply-side option for use as the avoided unit for
future capacity solicitations.

     Competitive Bidding - In July 1992, the MPSC issued an order establishing
a competitive bidding framework for future electric capacity solicitations for
Detroit Edison.  The MPSC directed Detroit Edison to proceed with a capacity
solicitation proceeding based on its 1992 IRP, which outlined Detroit Edison's
long-range plan for meeting its customers' electricity needs, and to submit an
RFP to meet the need for any future electric capacity.  On May 1, 1995, Detroit
Edison filed its preliminary RFP to solicit bids for the acquisition of new
capacity starting in the year 2004.  The filing describes Detroit Edison's
future requirements for additional generating capacity and addresses the role
competitive bidding will play in meeting that capacity need.  To better serve
its customers in an increasingly competitive marketplace, Detroit Edison is
proposing customer load management options which have the potential to provide
an additional 500 MW of peak reduction by the year 2003.  On July 14, 1995,
Detroit Edison updated its case to reflect the MPSC's June 19, 1995 Retail
Wheeling order.  On March 29, 1996, an MPSC ALJ issued a PFD finding a capacity
need and recommending immediate implementation of the retail wheeling
experiment.  The PFD did not recommend that competitive capacity 


                                      18
<PAGE>   21

solicitation be undertaken at this time.  Exceptions to the PFD have been
filed and Detroit Edison awaits the final order of the MPSC.

     Retail Wheeling - The MPSC has been considering the propriety of retail
wheeling programs.  On June 19, 1995, the MPSC issued a final order finding
that an experimental retail wheeling program is in the public interest and
established rates and charges for the five-year experimental program.  Under
the program, retail wheeling customers would make their own arrangements to
procure power.  Implementation of the experimental program would be limited to
90 MW for Detroit Edison and will be coordinated with Detroit Edison's next
solicitation of new capacity.  Detroit Edison's identified need date for new
capacity is 2004.  The MPSC Staff supported a need date of 1997 and recommended
that the experiment should begin in 1998.  The MPSC Staff is now recommending
that the MPSC open a new docket to consider a much larger retail wheeling
experiment than the 90 MW ordered previously.

     On July 19, 1995, Detroit Edison filed a claim of appeal of the MPSC's
April 11, 1994 interim order and June 19, 1995 final order with the Michigan
Court of Appeals.  Along with other claims, Detroit Edison asserts that the
MPSC lacks authority to compel Detroit Edison to undertake retail wheeling
involuntarily and that the rates, terms and conditions for retail wheeling
transmission service are subject to federal rather than state jurisdiction.
Appeals and/or cross appeals of the MPSC's retail wheeling orders have also
been filed by Consumers, Dow Chemical Company, ABATE and the Michigan Attorney
General.

     Commercial and Industrial Rates - Detroit Edison is continuing to address
its competitive status by entering into long-term service contracts with
certain of its large commercial and industrial customers.  These contracts must
be approved by the MPSC prior to implementation.  At December 31, 1996 and 1995
these contracts accounted for revenues of approximately $299 million and $208
million, respectively.  While there are revenue reductions associated with
these long-term service contracts, Detroit Edison believes they are
strategically advantageous.

     Capacity and Energy Purchase - On October 25, 1995, the MPSC issued an
order approving Detroit Edison's long-term capacity and energy purchase from
Ontario Hydro.  The purchase is for 300 MW, on a seasonal basis from mid-May
through mid-September for the years 1996 through 2001.  This purchase will
offset a concomitant agreement to lease 312 MW of Detroit Edison's 917 MW
Ludington capacity entitlement to The Toledo Edison Company for essentially the
same time period.  The net economic effect of the Ludington lease and the
Ontario Hydro purchase will be to provide Detroit Edison's  customers with an
estimated reduction in PSCR expense of $74 million which will be passed through
to customers through the PSCR clause.

     FEDERAL ENERGY REGULATORY COMMISSION.  Detroit Edison is subject to the
general jurisdiction of the FERC with respect to accounting, sales for resale
in interstate commerce, certain transmission services, issuances of securities,
the licensing of Ludington and other matters.  Detroit Edison's electric
transmission facilities, interconnected with those of Ontario Hydro at the
United States - Canada border, are subject to safety regulation by various
departments of the United States government and to a permit administered by the
ERA.  The transmission of electric energy to Ontario Hydro is subject to
regulation by the FERC and the ERA.

     On April 24, 1996, the FERC issued Orders 888 and 889.  Order 888 requires
public utilities to file open access transmission tariffs for wholesale
transmission services in accordance with non-discriminatory terms and
conditions established by the FERC.  On March 1, 1997 the joint transmission
tariff filed for Detroit Edison became effective.  Order 888 also permits the
recovery of stranded costs on a case by case basis.

     Order 889 requires public utilities to obtain transmission information for
wholesale transactions through a system on the Internet.  Public utilities must
separate transmission operations and reliability functions from wholesale
marketing functions.

     Detroit Edison is currently unable to estimate the revenue impact, if any,
of these newly required tariffs and procedures.

     For further information on the FERC proceedings, see Item 7 - Management's
Discussion and Analysis of Financial Condition and Results of Operations.

     NUCLEAR REGULATORY COMMISSION.  The NRC has regulatory jurisdiction over
all phases of the operation, construction (including plant modifications),
licensing and decommissioning of Fermi 2.  Reports on plant operation are filed
with the NRC on a periodic basis.  The scope of regulation is such that from
time to time assertions may be made that deviations from prescribed standards
and the unit's operating license have occurred.  Assertions of such a nature
are subject to the NRC's investigative, administrative and appeal procedures
and are considered to be pending until such time as review within the NRC is
completed.  At the conclusion of an investigation, the NRC may assess a fine
which should, in accordance with NRC regulations, be calculated in a manner
designed to take into account the severity, length and safety significance of
the alleged infraction.  In June 1996, Detroit Edison paid a fine of $50,000
for failure to take prompt action to identify and correct a potential common
mode failure of water pumps.

     On May 8, 1996, the NRC issued the fifteenth SALP report on Fermi 2
operations during the period from April 1994 through March 1996.  The NRC
assessment of nuclear activities was good overall.  The next SALP period is
expected to end in June 1997.

     The NRC, in a September 1996 Draft Policy Statement on the Restructuring
and Economic Deregulation of the Electric Utility Industry, indicated that it
was monitoring legislative and regulatory activities promoting competition and
restructuring for the 


                                      20

<PAGE>   23

purpose of assuring licensee's financial qualification and ability to fund
decommissioning expenses.

     By letter dated October 9, 1996, the NRC requested all reactor licensees,
including Detroit Edison, to submit information concerning the adequacy and
availability of nuclear power plant design basis information.  On February 7,
1997, Detroit Edison responded to the NRC indicating that it had reasonable
assurances that its plant design information was adequate.

     See Note 2 for further information on matters related to Fermi 2.

     ENVIRONMENTAL MATTERS

     Detroit Edison, in common with other electric utilities, is subject to
applicable permit, and associated record keeping, requirements and to
increasingly stringent federal, state and local standards covering, among other
things, particulate and gaseous stack emission limitations, the discharge of
effluents (including heated cooling water) into lakes and streams and the
handling and disposal of waste material.  In November 1990, the Federal Clean
Air Act was amended to further strengthen federal regulations governing air
emissions.  For further information on matters related to the 1990 Amendments
to the Federal Clean Air Act, see Item 7 - Management's Discussion and Analysis
of Financial Condition and Results of Operations.

     Through 1996, Detroit Edison's capital expenditures for environmental
control and protection facilities were approximately $2.9 billion.  Detroit
Edison's 1997 capital expenditure budget for environmental protection is
approximately $8 million.

     AIR.  Detroit Edison's operations are subject to environmental regulations
of the EPA, the State of Michigan and Wayne County.  Under the Federal Clean
Air Act of 1970, as amended, the EPA has the authority to adopt and implement
additional regulations in support or in substitution of state and local
enactments where the EPA deems such enactments to be deficient in relation to
its regulations.

     Title III of the Clean Air Act Amendments of 1990, Hazardous Air           
Pollutants, requires EPA to conduct two studies specifically related to
emissions from electric utility steam generating units and report the results
to Congress.  In the first utility study, EPA must assess the hazards to public
health reasonably anticipated to occur from these emissions.  The administrator
can regulate utility emissions if the study results indicate it is appropriate
and necessary to do so.  The report to Congress was to be submitted November
15, 1993.  It has not yet been completed.  EPA's second utility study is
specific for mercury and was to have been completed by November 15, 1994.  The
report to Congress for this study has also been delayed.  In May 1993, the
Michigan Environmental Science Board recommended that the Governor direct the
MPSC to require utilities to compile an accurate emission inventory.  Detroit
Edison has submitted such information to the MPSC.  The State of Michigan's
Mercury Pollution Prevention Task Force's final report, released in April 1996,
reviewed sources of mercury and 



                                      21
<PAGE>   24


recommended action programs for reduction of mercury discharges to the
environment from six main segments of society.  The recommendations for the
utility industry focused on encouraging the EPA to finalize its mercury study
reports to Congress and the MPSC and utilities to support additional research
to determine the full environmental costs of mercury emissions.  The report
also urged continued Michigan utility support of renewable energy projects and
asked the utilities to develop a plan with timetables and goals to further
reduce mercury usage or emissions.  At this time, until the congressional
studies are complete and resulting regulations, if any, are promulgated, the
impact upon Detroit Edison cannot be determined.

     WATER.  NPDES permits for Detroit Edison's power plants are issued by the
MDEQ pursuant to delegation by the EPA under the Federal Clean Water Act.  Two
renewal permit applications will be filed in 1997.  The NPDES permit for the
Fermi 2 Power Plant was issued on May 31, 1996.  A petition for a contested
case hearing challenging the issuance of the permit was filed in July.  In
September, 1996, the MDEQ filed a briefing memo recommending approval of the
hearing request.  An October 7, 1996 letter from the ALJ announced the matter
will now be moved to hearing.  While it is unknown what the outcome of the
hearing will be, the Fermi 2 permit remains in effect.  Permit renewal
applications for six other plants have been submitted (in 1996 and earlier);
those existing expired permits remain effective until new permits are issued or
denied.

     Detroit Edison is required to demonstrate that the cooling water intake
structures at all of its facilities reflect the "best technology available for
minimizing adverse environmental impact."  Detroit Edison filed such
demonstrations in July 1976 and the MDEQ Staff accepted all except those
relating to the St. Clair and Monroe Power Plants.  The MDEQ Staff rejected the
St. Clair demonstration and requested additional information, which was
submitted.  The MDEQ Staff never made a formal initial decision about the
intake at Detroit Edison's Monroe Power Plant but requested additional
information which was submitted on alternative intake technologies.  In the
event of a final adverse decision, Detroit Edison may be required to install
additional control technologies to further minimize the impact.

     Detroit Edison was required under its Monroe Power Plant NPDES permit to
demonstrate that thermal discharge from the plant does not cause an adverse
environmental impact on Lake Erie.  Such demonstration was submitted to the
MWRC and subsequently approved in 1976.  The demonstration has been under
review by the EPA which indicated that it was unable to concur in the
acceptability of the demonstration until additional information had been
provided with respect to the cooling water intake effects of the plant.
Additional information was submitted, but it is unknown at this time when this
issue will be resolved, or what the impact, if any, upon Detroit Edison will
be.

     WASTES AND TOXIC SUBSTANCES.  The Michigan Solid Waste and Hazardous Waste
Management Acts, the Michigan Environmental Response Act and the Federal
Resource Conservation and Recovery Act, Toxic Substances Control Act, and
CERCLA regulate Detroit Edison's handling, storage and disposal of its waste
materials.


                                      22
<PAGE>   25

     A nationwide environmental problem is the discovery of improperly disposed
of, hidden or buried hazardous wastes.  Detroit Edison has extensive property
holdings, including approximately 400 miles of transmission corridors which are
accessible to the public.  Detroit Edison could be responsible for clean-up of
wastes found on its property, despite the fact that the dumping may have
occurred without Detroit Edison's permission.

     Detroit Edison's Lulu-Milan transmission corridor in northwestern Monroe
County was used as a dump site for drums of paint sludges, solvents and some
PCB's and a portion of the corridor and adjoining property is listed on the
State's "Priority List of Environmental Contamination Sites."  Although not
responsible for placing the drums there, Detroit Edison has spent approximately
$550,000 on clean-up and disposal costs.  In June 1993, Detroit Edison and the
MDEQ reached an agreement to hire contractors to perform additional
investigative and remedial work at the site.  While the costs will be shared
between Detroit Edison and the state, it is impossible at this time to predict
what impact this will have upon Detroit Edison.

     See Note 12 for information on the Carter Industrials site matter.

     A landfill site abandoned by the South Macomb Disposal Authority and now
owned in part by Detroit Edison is being surveyed by the MDEQ for possible
contamination.  Detroit Edison could be required to contribute toward clean-up
costs, if any occur.  It is unknown at this time what impact, if any, this
situation will have upon Detroit Edison.

     Detroit Edison has received letters from the EPA requesting information
about its involvement with the following sites of identified contamination in
Michigan:  Rasmussen Dump site in Green Oak Township, Livingston County;
Metamora Landfill site in Lapeer County; and the Pioneer Equipment Company site
in Detroit.  Detroit Edison has examined its records and finds no evidence of
any involvement at these sites.  This information has been communicated to the
EPA, but it remains unknown what impact, if any, the EPA's ongoing
investigations will have upon Detroit Edison.

     In February 1992, Detroit Edison received formal notice from the MDEQ that 
the Port of Monroe Landfill Site had been identified as a site of environmental
contamination.  Also in February 1992, after an investigation of its records,
Detroit Edison sent a letter to the MDEQ stating its belief that it has never
disposed of hazardous material at the Port of Monroe Landfill Site.  On March
14, 1994, the MDEQ sent formal notice to the PRPs (but not to Detroit Edison)
that it is seeking reimbursement for its past costs and interest totaling
$750,000.  The PRPs sent a letter to Detroit Edison on April 8, 1994 advising
that they will seek a contribution from Detroit Edison on grounds that they
believe it to be a party despite the MDEQ's decision not to include it.  It is
unknown what impact, if any, this situation will have upon Detroit Edison.

     On January 10, 1997, Detroit Edison received a letter from the EPA
requesting its presence at a meeting regarding future clean-up activity at the
Ramona Park Landfill Superfund site in Utica, Michigan.  Detroit Edison had
previously provided a response to an EPA information request indicating that it
had found no evidence of involvement with 


                                      23
<PAGE>   26

the site.  It is unknown at this time what impact, if any, this situation
will have on Detroit Edison.

     On February 6, 1997, Detroit Edison received a letter from Southeastern
Michigan Gas Company regarding a facility in Marysville, Michigan which Detroit
Edison had operated in the past.  Southeastern Michigan Gas has requested that
an investigation be conducted to determine if the property is contaminated.  It
is unknown at this time what impact, if any, this situation will have on
Detroit Edison.

     In March 1989, the EPA served Detroit Edison with an investigative
subpoena requesting extensive information regarding Detroit Edison's PCB
activities.  Detroit Edison responded to the investigative subpoena in June
1989.  It is unknown at this time what impact, if any, the investigation will
have upon Detroit Edison.

     EPA rules for underground storage tanks became effective in December 1988.
These rules are now administered by the State of Michigan and contain
requirements on new tank system installations, leak detection monitoring,
notification and clean-up of leaks, corrosion resistance for new and existing
tank systems and spill prevention.  Detroit Edison has 61 regulated underground
storage tanks containing petroleum products.  All of the tanks have been
upgraded to "new tank standards", in accordance with further review of the
rules, except for two tanks and two piping systems that still need upgrading or
replacement by December 22, 1998, which are estimated to cost Detroit Edison
approximately $500,000 to complete.

     On July 1, 1991, the Michigan Environmental Response Act ("Act 307")
became effective.  The law is patterned after the CERCLA and gives the MDEQ
authority to list sites of environmental contamination and bring about
environmental clean-ups within the State of Michigan.  Several Detroit
Edison-owned properties are on the Act 307 list as a result of diesel oil
releases or dredged disposal operations, including portions of the Superior
Station and portions of the St. Clair and Monroe Power Plants.  In April, 1996,
the MDEQ conducted an Integrated Assessment on Detroit Edison owned property,
formerly known as the Monroe City Landfill, located next to the Monroe Power
Plant.  The site was on the State of Michigan's list of contaminated sites and
the CERCLA list.  In October, 1996, the Company received a copy of the report
and a letter from the MDEQ indicating that it was recommending that the site be
designated "No Further Remedial Action Planned."

     In 1993, Detroit Edison received a letter from the MDEQ requesting 
information regarding the Satterlee-Sumpter Township landfill site in Wayne
County.  In April 1994, Detroit Edison received a letter formally naming it as
a PRP in the case and requesting Detroit Edison, along with the other PRPs, to
conduct a remedial investigation of the site and to pay past costs incurred by
the State.  The PRPs have met with the MDEQ to clarify the extent of the
desired investigation. At this time, it is impossible to predict what the
impact upon Detroit Edison will be.


                                      24

     Detroit Edison received approval from the MDEQ on October 5, 1993 to close
its hazardous waste storage facility at its Warren Service Center.  The
facility's hazardous waste storage area has been closed but the issue of
corrective actions at solid waste management units has not yet been addressed
by the MDEQ or the EPA.

     The federal Low-Level Radioactive Waste Policy Act makes each state
responsible for the disposal of low-level radioactive waste situated within
each state's borders.  In June 1992, the United States Supreme Court upheld
most of the provisions of this statute.  The Court upheld the responsibility of
each state to develop low-level waste facilities, but declared a provision
requiring the state to take title to low-level radioactive waste in 1996 to be
unconstitutional.

     For further information on nuclear waste disposal,  see "Fuel Costs and
Supply - Nuclear."

Results of Operations.

EMPLOYEES AND EXECUTIVE OFFICERS

     EMPLOYEES.  The total number of employees of the Company was 8,526 (of
which 8,423 employees were employed by Detroit Edison) with an average length
of service of approximately 18 1/2 years.  Of these, 3,710 employees are
represented by unions under two collective bargaining agreements.  One
agreement expires in June 1999 for 3,161 employees and the other agreement
expires in August 2000 for 549 employees.

ITEM 3 - LEGAL PROCEEDINGS.

     Detroit Edison in the ordinary course of its business, is involved in
a number of suits and controversies including claims for personal injuries
and property damage and matters involving zoning ordinances and other
regulatory matters.  As of December 31, 1996, Detroit Edison was named as
defendant in 150 lawsuits involving claims for personal injuries and
property damage and had been advised of 26 other potential claims not
evidenced by lawsuits.

     From time to time Detroit Edison has paid nominal penalties which were
administratively assessed by the United States Coast Guard, United States
Department of Transportation under the Federal Water Pollution Control Act,
as amended, with respect to minor accidental oil spills at Detroit Edison's
power plants into navigable waters of the United States.  Payment of such
penalties represents full disposition of these matters.


                                      26
<PAGE>   29
     On May 28, 1996, an order was issued by the Circuit Court for Wayne
County, Michigan certifying a plaintiff class (Gilford, et al v Detroit
Edison) in a lawsuit claiming that Detroit Edison had engaged in age and
racial discrimination.  Detroit Edison has requested leave to appeal the
class certification to the Michigan Supreme Court and has requested a stay
of proceedings.  A notice has been sent to potential class members,
however, the size of the potential class will not be determinable until
late May 1997 at the earliest.  Detroit Edison is of the opinion that the
allegations of discrimination are without merit.

     Three Detroit Edison employees have filed a lawsuit in the Circuit
Court for Wayne County, Michigan (Sanchez, et al v Detroit Edison) alleging
age and national origin discrimination.  The plaintiffs, two of whom
indicate they are members of the Gilford class and one of whom indicates he
may be a member of the Gilford class, seek to represent a group of

     At December 31, 1996, there were 145,119,875 shares of the Company's
Common Stock outstanding.  These shares were held by a total of 132,839
shareholders.

     The Company's By-Laws provide that Chapter 7B of the Michigan Business
Corporation Act ("Act") does not apply to the Company.  The Act regulates
shareholder rights when an individual's stock ownership reaches at least 20
percent of a Michigan corporation's outstanding shares.  As a result of the
amendment, a shareholder seeking control of the Company cannot require the
Company's Board of Directors to call a meeting to vote on issues related to
corporate control within 10 days, as stipulated by the Act.

     The amount of future dividends will depend on the Company's earnings,
financial condition and other factors, including the effects of utility
restructuring efforts, each of which is periodically reviewed by the Company's
Board of Directors.

ITEM 7 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

DTE ENERGY COMPANY, THE DETROIT EDISON COMPANY AND SUBSIDIARY COMPANIES
- --------------------------------------------------------------------------------

This discussion and analysis should be read in conjunction with the
Consolidated Financial Statements and accompanying Notes thereto, contained
herein.

CORPORATE STRUCTURE

Effective January 1, 1996, DTE Energy Company became the parent holding company
of The Detroit Edison Company ("Detroit Edison").  On January 1, 1996, the
holders of Detroit Edison's common stock exchanged such stock on a
share-for-share basis for the common stock of DTE Energy Company ("Company").
In addition, certain non-utility subsidiaries of Detroit Edison were
transferred to the Company.  A number of non-utility affiliates have been
established by the Company with the intent of pursuing non-regulated businesses
apart from the regulated operations of Detroit Edison.

     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.  Detroit
Edison represents approximately 98.7% of the Company's assets at December 31,
1996.

RESULTS OF OPERATIONS

For the year ended December 31, 1996, the Company's net income was $309.3
million, or $2.13 per common share, down from the $405.9 million, or $2.80 per
common share earned in 1995.  The decrease in net income was due to a $149.2
million ($97 million after-tax), or $0.67 per share, special charge to net
income following completion of Detroit Edison's review of its steam heating
operations.  Without the special charge, 1996 earnings per common share would
have equaled the $2.80 reported a year ago.

     For the year ended December 31, 1995, the Company's net income was $405.9
million, or $2.80 per common share, up 4% from the $390.3 million, or $2.67 per
common share earned in 1994.  The increase in net income was due to higher
sales of electricity in 1995.  The sales increase was partially offset by
higher operating expenses, including a non-cash loss of $42 million ($32
million after-tax), or $0.22 per common share, on Detroit Edison's steam
heating business due to the Company's adoption in the fourth quarter of 1995 of
Statement of Financial Accounting Standards No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of"
("SFAS No. 121").

     For the year ended December 31, 1994, the Company's net income was $390.3
million, or $2.67 per common share, a decrease of 20.5% from the $491.1
million, or $3.34 per common share earned in 1993.  The decrease in net income
was due in part to a January 21, 1994 order by the Michigan Public Service
Commission ("MPSC"), which reduced Detroit Edison's rates by $78 million
annually and increased depreciation and operation expenses by $84 million
annually.  In addition, accretion income decreased and amortization of the
Fermi 2 nuclear power plant phase-in plan increased significantly in 1994.
Also, Detroit Edison incurred additional charges at the Fermi 2 nuclear power
plant, which was out of service in 1994 due to equipment failure, for
maintenance expenses and the establishment of a reserve for estimated Fermi 2
capacity factor performance disallowances during the period 1994-1998.  The
decrease in net income was limited by higher system sales and lower interest
expense due to the early redemption and refinancing of higher cost debt and the
redemption of maturing debt.

     At December 31, 1996, the book value of the Company's common stock was
$23.69 per share, an increase of 0.3% since December 31, 1995.  Return on
average total common shareholders' equity was 8.9% in 1996, 11.8% in 1995 and
11.6% in 1994.

     The Company's ratio of earnings to fixed charges for 1996, 1995 and 1994
was 2.69, 3.21 and 3.13, respectively.  The Company's ratio of earnings to
fixed charges and preferred stock dividends for 1996, 1995 and 1994 was 2.49,
2.82 and 2.73, respectively.

OPERATING REVENUES

Total operating revenues increased (decreased) due to the following factors:

</TABLE>


Rate Changes

The January 21, 1994 MPSC rate order reduced Detroit Edison's rates by $78
million annually.  In keeping with the MPSC's recognition of the need for
industrial customers to be competitive, the January 1994 rate reduction was
allocated among the various classes of customers approximately as follows:
Industrial-$43 million, Commercial-$24 million, Residential-$10 million and
Governmental-$1 million.

     Detroit Edison has entered into, and the MPSC has approved, long-term
service contracts with large commercial, automotive and other industrial
customers.  While there are revenue reductions associated with these long-term
service contracts, Detroit Edison believes they are strategically advantageous.

     The decreases in power supply cost recovery clause revenues have resulted
from lower average unit costs of fuel and purchased power.

</TABLE>

1996

Residential sales decreased due to cooler summer weather, partially offset by
increases from growth in the customer base.  Commercial and industrial sales
increased due to improved economic conditions.  Higher industrial sales reflect
strong demand in the automotive and construction sectors.  Sales to other
customers increased due to higher sales to wholesale for resale customers.

1995

Residential and commercial sales increased due to substantially warmer summer
weather increasing air conditioning and cooling-related loads and colder fall
weather increasing heating-related loads in the fourth quarter.  Improved
economic conditions spurred higher sales to commercial, automotive and other
industrial customers.  Sales to other customers increased due to higher sales to
wholesale for resale customers.

Interconnection Sales

Interconnection sales represent sales between utilities to meet energy needs as
a result of demand and/or generating unit availability.

1996

Interconnection sales decreased due to lower demand for energy.

1995

Interconnection sales increased due to improved availability of energy for sale
and lower dispatch prices in meeting the increased demand for energy during the
warmer summer and colder fall period.

Fermi 2 Capacity Factor Performance Standard and Reduced Turbine Efficiency
Reserves

These reserves are discussed in Note 3 of the Notes to Consolidated Financial
Statements.

1996

The decrease in average unit cost was due to declining fuel prices resulting
from greater use of lower-cost western low-sulfur coal and a decrease in
nuclear fuel costs.

1995

The decrease in average unit cost was due to declining fuel prices resulting
from greater use of lower-cost western low-sulfur coal, lower coal contract
buyout expense and increased lower-cost nuclear generation.

Other Operation

1996

Detroit Edison's other operation expense increased due primarily to operating
expenses related to new computer systems ($12 million), higher nuclear plant
($9.5 million), administrative and general ($8.2 million), employee benefits
($7.9 million) and sales ($7.7 million) expenses, lump sum payments to union
employees ($4.3 million) and higher customer accounts expenses ($3 million).
These increases were partially offset by lower incentive award expenses related
to a shareholder value improvement plan ($14.2 million) and major storm
expenses ($5.7 million) and expenses recorded in the year earlier period for
the write-off of obsolete and excess stock material ($12 million), the
Ludington Pumped Storage Plant fish mortality case ($8.4 million) and Electric
Power Research Institute dues ($4.8 million). In addition, the Company's other
operation expense increased due to non-utility operations ($8.2 million).

1995

Other operation expense increased due primarily to higher incentive award
expenses related to a shareholder value improvement plan ($14.5 million), higher
storm expenses ($13.1 million), an increase in a reserve for the write-off of
obsolete and excess stock material ($9 million), demand-side management expenses
($8.6 million) and a reserve for settlement of the Ludington Pumped Storage
Plant fish mortality case ($8.4 million).  These increases were partially offset
by lower nuclear plant expenses ($15.5 million), expenses recorded in the
year-earlier period for service quality claims ($8.7 million) and lower
uncollectible expense ($6.9 million).

<PAGE>   33

Maintenance

1996

Maintenance expense increased due to higher overhead and underground lines
support ($26.1 million), nuclear plant ($7.1 million) and station equipment ($7
million) expenses, partially offset by lower major storm expenses ($3.1
million).

1995

Maintenance expense decreased due primarily to lower nuclear ($17 million) and
fossil ($4.3 million) plant expenses.

Steam Heating Special Charges

1996

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 ($97 million after-tax).  The special charge included
a reserve for steam purchase commitments during the period from 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 system and
improvements in service to remaining customers.

1995

As the result of continuing losses in the operation of its steam heating
business, upon adoption of SFAS No. 121 in the fourth quarter of 1995, Detroit
Edison wrote off the remaining net book value of its steam heating plant assets
of $42 million.

Depreciation and Amortization

1996 and 1995

Depreciation and amortization expense increased due to increases in plant in
service, including internally developed software costs, and increased Fermi 2
decommissioning costs authorized by a January 1994 MPSC rate order.

Deferred Fermi 2 Amortization

1996 and 1995

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

1996 and 1995

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

1996

Taxes other than income taxes increased due to higher payroll and property
taxes, partially offset by lower Michigan Single Business Taxes.

1995

Taxes other than income taxes decreased due to lower payroll and property
taxes.

Income Taxes

1996

Income taxes decreased due primarily to lower pretax income.

1995

Income taxes increased due primarily to higher pretax income.

Other Income and (Deductions) - net

1996

Other deductions decreased due primarily to lower promotional practices expense
($5.3 million), expenses recorded in the year earlier period for the sale of
accounts receivable and unbilled revenues ($3.1 million) and the formation of a
holding company ($3.1 million) and lower corporate contributions ($2.9 million).

1995

Other deductions increased due to higher promotional practices expense ($8.3
million), expenses incurred in the formation of a holding company ($3.1
million) and joint-use contract costs ($2.7 million), partially offset by lower
expenses related to the sale of accounts receivable and unbilled revenues ($6.1
million) and a decrease in the write-off of premiums and expenses related to
the portion of Detroit Edison's 1989 Series A Mortgage Bonds not refinanced
($3.5 million).

Accretion Income

1996 and 1995

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 for Greenwood Unit No. 1 for the period that
plant was not allowed in rate base (1988-1993) and for $300 million of Fermi 2
plant costs being recovered from 1989 to 1998 with no return.  The annual
amount of accretion income recorded decreases each year through 1998.

Long-Term Debt Interest Charges

1996

Long-term debt interest charges decreased due to the early redemption of
Mortgage Bonds, partially offset by the issuance of Quarterly Income Debt
Securities ("QUIDS").

1995

Long-term debt interest charges increased due to the issuance of QUIDS and the
timing of the early redemption and refinancing of securities when economic.

Other Interest Charges

1996 and 1995

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

Preferred Stock Dividends of Detroit Edison

1996

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

1995

Preferred stock dividends of Detroit Edison decreased due to the exchange of a
portion of Cumulative Preferred Stock 7.75% Series for QUIDS and the conversion
and redemption of Cumulative Preferred Stock 5 1/2% Convertible Series.

LIQUIDITY AND CAPITAL RESOURCES

Private Securities Litigation Reform Act - Forward-Looking Statements

Certain information presented herein 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 Federal Energy Regulatory Commission ("FERC") tariffs, actual
sales, 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

Formation of a Holding Company

The business of energy supply is experiencing rapid change as competition,
coupled with statutory reform, is being introduced into the public utility
sector.  Competition is viewed by legislators and regulators, at both the
federal and state levels, as a method of reducing utility rates while
stimulating overall economic growth.

     In order to position itself for potential changes in the electric utility
industry, Detroit Edison adopted a holding company structure, effective January
1, 1996.  The new holding company structure, under which Detroit Edison is a
wholly-owned subsidiary of the Company, is designed to provide financial
flexibility for the development of new energy-related businesses.  It is also a
mechanism for separating the regulated utility business of Detroit Edison from
non-regulated businesses thereby protecting the utility business from the
potential risks of non-utility operations.

     Detroit Edison continues to review potential energy services as a method
of remaining competitive while diversifying within the scope of its core
business.  In addition, the Company anticipates that its affiliates may also
assist in overall customer satisfaction by offering energy-related services.

The Detroit Edison Company

The electric utility industry is facing serious issues as legislators and
regulators consider various proposals designed to reduce rates and promote
economic growth through competition.  Municipalization, deregulation,
cogeneration, independent power production, open access to transmission lines,
competitive bulk power supply markets and the unbundling of utility products
and services are issues under consideration.  There is also a recognition by
legislators and regulators that the stranded costs of utilities must be
addressed as deregulation proceeds.

Federal Energy Regulatory Commission

On April 24, 1996, the FERC issued Orders 888 and 889.  Order 888 requires
public utilities to file open access transmission tariffs for wholesale
transmission services in accordance with non-discriminatory terms and
conditions established by the FERC.  On July 9, 1996, Detroit Edison filed its
Pro-Forma Open Access Transmission Tariff in compliance with FERC Order 888.
The tariff sets forth the terms and conditions under which Detroit Edison will
supply wholesale Firm and Non-Firm Point-to-Point Transmission Service as well
as Network Integration Transmission Service (a service which allows the network
customer to integrate, economically dispatch and regulate its network resources
to serve its network load in a manner comparable to that in which the
transmission provider utilizes its transmission system to serve its native load
customers).  Detroit Edison's filing also included the development and cost
support for the rates to be charged for transmission service and the various
ancillary services that are required to be offered.  Order 888 permits the
recovery of stranded costs on a case by case basis.  The FERC has initiated
proceedings to review Detroit Edison's tariff filing.

     Order 888 also required that, on or before December 31, 1996, utilities
engaged in power pooling operations develop and submit to the FERC a joint
pro-forma open access transmission tariff applicable to power transactions
involving the facilities of both pool utilities, and reform underlying power
pool agreements to remove any unduly discriminatory provisions and permit open
membership for any interested bulk power market participants.

     Detroit Edison is a party to a power pooling agreement with Consumers
Energy Company.  In compliance with Order 888, on December 31, 1996, Detroit
Edison and Consumers Energy Company filed a joint pro-forma open access
transmission tariff and a joint transmission agreement that canceled prior
transmission sharing arrangements that were developed under the pooling
agreement.  Neither Detroit Edison nor Consumers Energy Company were able to
agree as to what other modifications should be made to the pooling agreement.
Therefore, on December 31, 1996, Detroit Edison unilaterally submitted a
proposed amendment requesting that the FERC approve termination of the pooling
agreement as of April 30, 1997.  On the same day, Consumers Energy Company
unilaterally submitted a proposed amendment that would delete current membership
requirements and permit the current parties to consider membership requests
submitted by any creditworthy bulk power market participant.

     Since January 3, 1997, public utilities have been required by Order 889 to
obtain transmission information for wholesale transactions through a system on
the Internet.  Public utilities must separate transmission operations and
reliability functions from wholesale marketing functions.

     FERC has also issued a Notice of Proposed Rulemaking ("NOPR") on Capacity
Reservation Transmission Tariffs ("CRT").  The NOPR requested comment by
October 21, 1996, on whether there are certain disadvantages inherent in
offering transmission service on both a network and single point-to-point basis
and whether comparability can be better accomplished using a different
methodology.  The proposed CRT approach suggests that no later than December
31, 1997, all pro-forma 
                                        
                                        
                                       32
                                        
<PAGE>   35

point-to-point and network service be replaced with a single point-to-point
tariff that provides for reservation-based transmission service for all
jurisdictional (wholesale sales and wholesale and retail transmission) service.

     Detroit Edison is currently unable to estimate the revenue impact, if any,
of these newly required tariffs and procedures.

Michigan Public Service Commission

The MPSC has been considering various proposals to implement a competitive
utility environment as recommended by Michigan Governor John Engler and the
Michigan Jobs Commission ("MJC") in January 1996.

     On December 19, 1996, the MPSC Staff Report on Electric Industry
Restructuring was filed with the MPSC.  The Staff Report recognized that
Michigan utilities should have the opportunity to prepare for competition and
be able to maintain their financial health and, among other things,
recommended:

   1.   A phase-in program beginning in 1997 for direct customer access (also
        known as customer choice) by 2004, with the phase-in of load at the rate
        of approximately 2 1/2% (225 megawatts ("MW")) in 1997, 5% in 1998, 7
        1/2% in 1999 and 10% total in 2000 for Detroit Edison.  These blocks
        would be allocated among customers through a bidding process. In 2001,
        all commercial and industrial customers served at primary voltage would
        be eligible for direct access and in 2004, all remaining customers would
        be eligible for direct access. 

   2.   A freeze on base electric rate increases in conjunction with the
        implementation of a direct customer access program and the suspension
        of the power supply cost recovery clause during the transition period
        (ending 2004) for direct customer access.  For generation costs, the
        moratorium would remain effective until a customer class has the option
        of direct access.  A fixed level of fuel and purchased power costs
        would be subject to recovery in rates during the transition period.

   3.   The functional separation of generation, transmission and
        distribution service for rate purposes.  Generation costs would be
        subject to competitive considerations, while transmission and
        distribution costs would be regulated, but subject to limited
        performance based regulation ("PBR").  A CPI-1% methodology would be
        used for regulation of transmission and distribution costs during the
        transition period.  The PBR process would be subject to review at
        five-year intervals, with the first review in 2001.

   4.   The recovery of transition costs or stranded costs, (costs that
        were incurred during the regulated era that would be above prevailing
        market prices in a competitive marketplace and costs that were incurred
        to facilitate the transition from a regulated monopoly status to
        competitive market status), which the Staff Report indicated includes:
        (a) regulatory assets, (b) nuclear capital costs, (c) contract capacity
        costs in power purchase agreements, (d) employee related restructuring
        costs, including retraining and (e) other costs related to implementing
        restructuring (establishing an independent system operator, creating
        new billing software systems, new metering systems, etc.) would be
        recovered primarily through securitization and secondarily through a
        transition charge.  This transition charge would commence when a
        customer takes direct access and would continue through 2007.  These
        stranded and transition costs are expected to total approximately $2.8
        billion for Detroit Edison.

   5.   Securitization is a method of refinancing debt that lowers electric
        cost for all customers.  The securitization proposed would be
        implemented by the issuance of "rate reduction bonds" by a trust to be
        created for such purpose.  The proceeds from the sale of such bonds
        would be used to reduce the amount of Detroit Edison's outstanding debt
        and equity.  Securitization would result in a reduction in base rates
        that would be partially offset by a charge for bond repayment. The
        overall impact would be a reduction in customer rates.  In the case of
        Detroit Edison, this would amount to a 9% or approximately $300 million
        annual rate reduction.

   6.   Eligible power suppliers would be limited to those able to grant
        comparable and reciprocal direct access to the Michigan host utility.

   7.   A requirement that local utilities provide standby power for two
        years, but not after 2001.

   8.   The collection of nuclear decommissioning and site security costs
        by means of a non-by-passable charge.

     On December 20, 1996, the MPSC issued an order which provided for three
public hearings and a written comment period on the Staff Report during January
1997.  Further, on 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.  These filings are due
March 7, 1997, and would include:  detailed calculations of anticipated
stranded costs and transition charges, items that the utility would expect to
securitize if authorized, allocation of direct access capacity and alternatives
to the proposed phase-in program, proposed direct access service charges and
conditions of service, standby service options for direct access customers,
transmission constraints or limitations, development of an independent system
operator, and methods to alleviate concerns regarding market power in a
competitive environment.  Other Michigan electric utility companies may also
make informational filings by March 7, 1997.  The MPSC will hold four public
hearings on the informational filings on March 25, March 26, April 2 and April
3, 1997, and will receive additional written comments by April 7, 1997.

     If the Staff Report recommendations are adopted by the MPSC, a number of
legislative and regulatory changes would be necessary for implementation, and
the regulatory process in Michigan would be altered.  The Staff Report provides
for the recovery of regulatory assets, capital costs of Fermi 2, and costs
incurred to implement the transition to competition.  Also, if the Staff Report
in its present form is adopted, the non-nuclear generation segment of Detroit
Edison's business would not qualify for SFAS No. 71 accounting following the
transition period.  However, Detroit Edison believes that the nuclear
generation and transmission and distribution segments of its business will
continue to be regulated and qualify under the accounting model prescribed by
SFAS No. 71.

ITEM 7 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

DTE ENERGY COMPANY, THE DETROIT EDISON COMPANY AND SUBSIDIARY COMPANIES
- --------------------------------------------------------------------------------

     While Detroit Edison is unable to predict the final outcome of the FERC
rulemaking and the MPSC Staff Report, substantial changes in regulation and
legislation are anticipated.

Nuclear Regulatory Commission ("NRC")

Detroit Edison has established external trust funds for its nuclear
decommissioning costs and believes that current provisions are adequate for
decommissioning.  The NRC, in a September 1996 Draft Policy Statement on the
Restructuring and Economic Deregulation of the Electric Utility Industry,
indicated that it was monitoring legislative and regulatory activities
promoting competition and restructuring for the purpose of assuring licensee's
financial qualification and ability to fund decommissioning expenses.

Cash Generation and Cash Requirements

Consolidated Statement of Cash Flows

The Company generates substantial cash flows from operating activities as shown
in the Consolidated Statement of Cash Flows.  Net cash from operating
activities, which is the Company's primary source of liquidity, was $1,079
million in 1996, $913 million in 1995 and $923 million in 1994.  Net cash from
operating activities increased in 1996 due primarily to changes in current
assets and liabilities, primarily as a result of the 1995 repurchase of
customer accounts receivable and unbilled revenues.  Net cash from operating
activities decreased slightly in 1995 as a result of the repurchase of $200
million of customer accounts receivable and unbilled revenues, partially offset
by higher non-cash charges to income and higher net income.

     Net cash used for investing activities increased in 1996 and 1995 due
primarily to higher utility and non-utility plant and equipment expenditures.

     Net cash used for financing activities increased in 1996 due primarily to
the redemption of preferred stock.  Net cash used for financing activities
decreased in 1995 due primarily to a decrease in funds used to reduce
short-term borrowings.  In 1994, as a result of plan changes, Detroit Edison
entered into the one-time purchase of common stock from the trustee of the
Detroit Edison Savings & Investment Plans.

Additional Information

On February 13, 1996, Detroit Edison issued $185 million of 7.625% QUIDS.
Also, on March 21, 1996, Detroit Edison redeemed all of the outstanding
Cumulative Preferred Stock, 7.68% Series, 7.45% Series and 7.36% Series,
totaling $185 million, at per share redemption prices of $101 plus accrued
dividends.

     During 1996, Detroit Edison purchased a total of $56.5 million of Mortgage
Bonds on the open market, consisting of $29.5 million of 7.74% 1993 Series J,
$26 million of 8.24% 1993 Series C and $1 million of 8.25% 1993 Series C.
These bonds have been canceled.

     Detroit Edison's requirements for scheduled long-term debt redemptions are
expected to be $144 million, $169 million, $219 million, $194 million and $119
million for 1997, 1998, 1999, 2000 and 2001, respectively.

     Detroit Edison's cash requirements for capital expenditures are expected
to be approximately $2.2 billion for the period 1997 through 2001.  In 1997,
cash requirements for capital expenditures are estimated at $448 million.
Environmental expenditures are expected to approximate $114 million for the
period 1997 through 2001, including expenditures for Clean Air Act compliance
requirements.  See "Environmental Matters" herein.

     Detroit Edison's internal cash generation is expected to be sufficient to
meet cash requirements for capital expenditures as well as scheduled long-term
debt redemption requirements.

     Detroit Edison had total short-term credit arrangements of approximately 
$464 million at December 31, 1996, under which $10 million of borrowings were
outstanding.

Non-Regulated Investments

Cash requirements for 1996 non-regulated investments and capital expenditures
were $60 million and are estimated to range from $300 million to $350 million
in 1997.  Non-regulated investments are expected to be externally financed.

     A non-recourse project financing arrangement is in place for PCI
Enterprises borrowings of up to $50 million, of which $39 million was
outstanding at December 31, 1996.  This arrangement is collateralized by
specific project assets.

     At December 31, 1996, DTE Capital Corporation had a $200 million Revolving
Credit Agreement, backed by a Support Agreement from the Company, under which
no borrowings were outstanding.

Capitalization

The Company's capital structure ratios (excluding long-term debt due within one
year) were as follows:

Fermi 2

Fermi 2 is a nuclear generating unit of Detroit Edison comprising 25% of its
total assets and 9% of its summer net rated capability.

     The commercial operation of Fermi 2, which began in 1988, completed Detroit
Edison's power plant construction program.  Detroit Edison has no current plans
for building any additional generating plants.  Ownership of an operating
nuclear generating unit subjects Detroit Edison to significant additional risks.
The nuclear plant is regulated by a number of different governmental agencies
concerned with public health, safety and environmental protection.
Consequently, Fermi 2 is subjected to greater scrutiny than a conventional
fossil-fueled plant.

     Fermi 2 was out of service in 1994 and part of 1995, and the unit operated
at a reduced power output through September 26, 1996, due to a December 1993
turbine-generator failure.  Major 


                                       34


<PAGE>   37

repairs were completed in 1994 and early 1995.  These repair costs were
approximately $80 million for which to date Detroit Edison has received partial
insurance payments of $70 million for property damage.  In addition, Detroit
Edison has received partial insurance payments of $74.2 million for replacement
power costs through December 31, 1996.

     Fermi 2 was shut down from September 27, 1996 to January 3, 1997, to
replace one-third of its nuclear fuel and install three new low pressure
turbines.  With the installation of these new turbines the unit is expected to
initially operate at 1,085 MW, up from 876 MW prior to this shutdown.  The $49
million cost of replacing the major turbine components was not covered by
insurance.  This cost was capitalized and is expected to be recovered in rates
because it is less than the cumulative amount available under the cap on Fermi
2 capital expenditures, a provision of the MPSC's December 1988 order.

     On January 17, 1997, there was an electrical component failure in the
switchyard outside the plant which resulted in the "motorizing" of the main
generator caused by incoming electricity from the Detroit Edison electrical
system.  As a result, the Fermi 2 plant was shut down to allow 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.  Operation of the reactor was not affected by this
incident.  Although the costs of repairs are expected to be covered by
insurance (subject to a $1 million deductible), this incident will require an
increase in the Fermi 2 capacity factor performance standard reserve for the
period 1997-1999 which will have an adverse effect on earnings in the first
quarter of 1997.  See Note 3 of the Notes to Consolidated Financial Statements.

     At December 31, 1996, Fermi 2 was insured for property damage and public
liability as discussed in Note 2 of the Notes to Consolidated Financial
Statements.  To the extent that insurable claims for replacement power,
property damage, decontamination, repair and replacement and other costs
arising from a nuclear incident at Fermi 2 exceed the policy limits of
insurance, or to the extent that such insurance becomes unavailable in the
future, Detroit Edison will retain the risk of loss.

     The Financial Accounting Standards Board is reviewing the accounting for
removal costs, including decommissioning of nuclear power plants.  If current
electric utility industry accounting practices for such decommissioning are
changed:  (1) annual provisions for decommissioning could increase, and (2) the
estimated cost for decommissioning could be recorded as a liability rather than
as accumulated depreciation.

Future Sales Growth

Since 1986, Detroit Edison's compounded annual electric power sales growth was
2% and peak demand growth was 2.6% (after adjusting for the effects of unusual
weather).  Electric power sales and system demand are expected to grow at
compounded annual rates of about 1.6% per year for the next 5 years.

Meeting Energy Demands

In 1996, Detroit Edison met peak demand through a combination of installed
generation, long-term purchases and seasonal capacity purchases.  It is
expected that peak demand in 1997 and later years will be met using the same
combination of resources.  Detroit Edison anticipates sufficient power will be
available for purchase as needed.

Inflation

Inflation is a measure of the purchasing power of the dollar.  Although the
current inflation rate is relatively low, its compound effect through time can
be significant, primarily in its effect on Detroit Edison's ability to replace
its investment in utility plants.

     The regulatory process limits the amount of depreciation expense
recoverable through revenues to the historical cost of Detroit Edison's
investment in utility plants.  Such amount produces cash flows which are
inadequate to replace such property in future years.  However, Detroit Edison
believes that it will be able to recover the increased cost of replacement
facilities when, and if, replacement occurs.

Environmental Matters

Protecting the environment from damage, as well as correcting past environmental
damage, continues to be a focus of state and federal regulators. Committees at
both the state and federal level are studying the effects of a wide array of
chemicals and electromagnetic fields on the environment, as well as the
possibility of global warming resulting from carbon dioxide emissions.
Legislation and/or rulemaking resulting from these and any future studies could
further impact the electric utility industry including Detroit Edison.

     The Environmental Protection Agency ("EPA") and the Michigan Department of
Environmental Quality have aggressive programs regarding the clean-up of
contaminated property.  Detroit Edison anticipates that it will be periodically
included in these types of environmental proceedings.  Further, additional
environmental expenditures, although difficult to quantify, will be necessary as
Detroit Edison prepares to comply with the phase-in of the 1990 Amendments to
the Federal Clean Air Act.  Detroit Edison currently meets the first phase of
sulfur dioxide emissions and nitrogen oxides emissions requirements.  The second
phase begins in the year 2000.  Detroit Edison currently burns some level of
low-sulfur coal (less than 1% sulfur) at all its coal-fired units and believes
it can meet the second phase sulfur dioxide emission requirements by either
increasing the amount of low-sulfur coal used at certain units, by purchasing
sulfur dioxide emission allowances, or by doing some combination of both,
depending upon which strategy proves to be the best economic choice. Current
projections indicate that annual fuel costs may increase by $13 million to $20
million in the period 2000-2009 in order to comply with new sulfur dioxide
emissions requirements. In addition, approximately $59 million in capital
expenditures may be necessary for nitrogen oxides emissions requirements.

     In November 1996, the EPA proposed new air-quality standards relating to
ozone and particulate air pollution.  The proposed new rules could lead to
additional controls on fossil-fueled power plants to reduce nitrogen oxides and
particulate emissions.  The Company is unable to predict at this time what
impact, if any, the proposed standards may have.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DTE ENERGY COMPANY, THE DETROIT EDISON COMPANY AND SUBSIDIARY COMPANIES
- --------------------------------------------------------------------------------

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES
- --------------------------------------------------------------------------------

CORPORATE STRUCTURE AND PRINCIPLES OF CONSOLIDATION - DTE Energy Company
("Company") is a Michigan corporation, incorporated in 1995, and an exempt
holding company under the Public Utility Holding Company Act.  The Company has
no significant operations of its own, holding instead the stock of an electric
utility and other energy-related businesses.  The Detroit Edison Company
("Detroit Edison"), a public utility incorporated in Michigan since 1967, is
the Company's largest operating subsidiary.  Detroit Edison represents
approximately 98.7% of the Company's assets at December 31, 1996.

     As a regulated public utility, Detroit Edison is engaged in the
generation, purchase, transmission, distribution and sale of electric energy in
a 7,600 square mile area in Southeastern Michigan.  The Company's service area
includes about 13% of Michigan's total land area, and about half of its
population (approximately five million people), electric energy consumption and
industrial capacity.

     On January 1, 1996, the holders of Detroit Edison's common stock exchanged
such stock on a share-for-share basis for the common stock of the Company. Also
on January 1, 1996, Detroit Edison declared a dividend to the Company in the
form of the stock of five subsidiaries:  DE Energy Services, Inc., DTE Capital
Corporation, Edison Development Corporation, Syndeco Realty Corporation and UTS
Systems, Inc.  Accordingly, the consolidated financial statements presented
herein include the financial results of operations of the Company and its
wholly-owned subsidiaries as if the Company's current holding company structure
form had existed in all periods shown.  For the periods presented, the
Company's operations and those of Detroit Edison are substantially the same.

     All significant intercompany balances and transactions have been
eliminated.  Investments in limited liability companies, partnerships and joint
ventures are accounted for using the equity method.

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS - The preparation
of 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.

REGULATION AND REGULATORY ASSETS AND LIABILITIES - Detroit Edison is subject to
regulation by the Michigan Public Service Commission ("MPSC") and the Federal
Energy Regulatory Commission ("FERC") with respect to accounting matters and
maintains its accounts in accordance with Uniform Systems of Accounts
prescribed by these agencies.  As a regulated entity, taking into account the
cost recovery restrictions contained in the December 1988 and January 21, 1994
MPSC rate orders and the provisions of the Energy Policy Act of 1992 ("Energy
Act"), Detroit Edison meets the criteria of Statement of Financial Accounting   
Standards ("SFAS") No. 71, "Accounting for the Effects of Certain Types of
Regulation."  This accounting standard recognizes the ratemaking process which
results in differences in the application of generally accepted accounting
principles between regulated and non-regulated businesses.  Detroit Edison has
recorded the regulatory assets listed below.  These regulatory assets are
deferred costs, which are normally treated as expenses in non-regulated
businesses, and are being amortized to expense as these costs are included in
rates and recovered from customers.  Continued applicability of SFAS No. 71
requires that rates be designed to recover specific costs of providing
regulated services and products, including regulatory assets, and that it be
reasonable to assume that rates are set at levels that will recover a utility's
costs and can be charged and collected from customers.  If the criteria of SFAS
No. 71 are no longer met due to various factors, including deregulation of all
or part of the business, a change in the method of regulation or a change in
the competitive environment for the regulated services, the regulatory assets
would have to be written off to expense at that time.

     As discussed in Management's Discussion and Analysis of Financial
Condition and Results of Operations, the December 19, 1996 MPSC Staff Report on
Electric Industry Restructuring, if adopted by the MPSC and Michigan
legislature as proposed, would alter the regulatory process in Michigan and
provide for a transition to competition for the non-nuclear generation segment
of Detroit Edison's business.  The Staff Report being considered provides for
the recovery of regulatory assets, capital costs of Fermi 2 and costs incurred
to implement the transition to competition.  Also, if the Staff Report in its
present form is adopted, the non-nuclear generation segment of Detroit Edison's
business would not qualify for SFAS No. 71 accounting following the transition
period.  However, Detroit Edison believes that the nuclear generation and
transmission and distribution segments of its business will continue to be
regulated and qualify under the accounting model prescribed by SFAS No. 71.

     Detroit Edison has recorded the following regulatory assets at December
31:

</TABLE>


     At December 31, 1996 and 1995, Detroit Edison had the following regulatory
liabilities:  (1) $315 million and $330 million, respectively, for unamortized
accumulated deferred investment tax credits, (2) $73 million and $53 million,
respectively, for Fermi 2 capacity factor and turbine efficiency disallowances
(see Note 3), and (3) $6 million and $22 million, respectively, for other
liabilities.

UNAMORTIZED LOSS ON REACQUIRED DEBT - In accordance with MPSC regulations
applicable to Detroit Edison, the discount, premium and expense related to debt
redeemed with refunding are amortized over the life of the replacement issue.

RECOVERABLE INCOME TAXES - See Note 6.

OTHER POSTRETIREMENT BENEFITS - See Note 13.

FERMI 2 PHASE-IN PLAN - An MPSC authorized phase-in plan, effective in January
1988, for Fermi 2, a nuclear generating unit, provided for gradual rate
increases in the early years of plant operation rather than a one-time
substantial rate increase which conventional ratemaking would provide.  SFAS
No. 92,

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

"Regulated Enterprises - Accounting for Phase-in Plans," permits the
capitalization of costs deferred for future recovery under a phase-in plan.
Accordingly, Detroit Edison recorded non-cash income of deferred depreciation
and deferred return totaling $506.5 million 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.  Amortization of
these deferred amounts totaled $102 million, $93 million and $85 million in
1996, 1995 and 1994, respectively.

FERMI 2 DEFERRED AMORTIZATION - The December 1988 MPSC rate order provides for
Detroit Edison's February 1990 purchase of Wolverine Power Supply Cooperative,
Inc.'s ("Cooperative") ownership interest in Fermi 2 for $513 million with a    
19-year principal amortization and associated interest of 8%, which is the
composite average of the Cooperative debt assumed by Detroit Edison at the time
of the purchase. Since the straight-line amortization of the asset exceeds the
revenues provided for such amortization during the first 10 years of the
recovery period, Detroit Edison is recording deferred amortization, a non-cash
item of income, totaling $67.2 million through 1999.  For 1996, 1995 and 1994,
the amounts deferred were $4.5 million, $6 million and $7.5 million,
respectively.  The deferred amounts will be amortized to operating expense as
the cash recovery is realized through revenues during the years 2000 through
2008.

UNITED STATES DEPARTMENT OF ENERGY ("DOE") DECONTAMINATION AND DECOMMISSIONING
- - The Energy Act provided for a fund to be established for the decommissioning
and decontamination of existing DOE uranium enrichment facilities.  Utilities
with nuclear units are required to pay for a portion of the cost by making
annual payments into the fund over a 15-year period.  The law directs state
regulators to treat these payments as a necessary and reasonable cost of fuel.
Detroit Edison recovers these costs through the Power Supply Cost Recovery
("PSCR") Clause.

ALLOWANCE FOR FUNDS USED DURING CONSTRUCTION ("AFUDC") - AFUDC, a non-operating
non-cash item, involves a regulatory accounting procedure whereby the
approximate interest expense and the cost of other (common and preferred
shareholders' equity) funds applicable to the cost of construction are
transferred from the income statement to construction work in progress in the
balance sheet.  The cash recovery of AFUDC, as well as other costs of
construction, occurs as completed projects are placed in service and related
depreciation is authorized to be recovered through customer rates.  Detroit
Edison capitalized AFUDC at 7.66% in 1996, 1995 and 1994.  Because the amount
of AFUDC computed for MPSC purposes has exceeded the amount computed using the
FERC formula, the excess was recorded as a regulatory asset and is being
amortized to operating expense over the service life of utility property.

TEMPORARY CASH INVESTMENTS - For purposes of the Consolidated Statement of Cash
Flows, the Company considers investments purchased with a maturity of three
months or less to be cash equivalents.

REVENUES - Detroit Edison records unbilled revenues for electric and steam
heating services provided after cycle billings through month-end.

PROPERTY, RETIREMENT AND MAINTENANCE, DEPRECIATION AND AMORTIZATION - Utility
properties are recorded at original cost less regulatory disallowances and an
impairment loss.  In general, the cost of properties retired in the normal
course of business is charged to accumulated depreciation.  Expenditures for
maintenance and repairs are charged to expense, and the cost of new property
installed, which replaces property retired, is charged to property accounts.
The annual provision for utility property depreciation is calculated on the
straight-line remaining life method by applying annual rates approved by the
MPSC to the average of year-beginning and year-ending balances of depreciable
property by primary plant accounts.  Provision for depreciation of Fermi 2,     
excluding decommissioning expense, was 3.26% of average depreciable property
for 1996, 1995 and 1994, except for $300 million being amortized over 10 years
commencing in 1989 and $513 million being amortized over 19 years commencing in
1990.  See Note 3.    Provision for depreciation of all other utility plant, as
a percent of average depreciable property, was 3.2% for 1996, 1995 and 1994.

SOFTWARE COSTS - Detroit Edison capitalizes the cost of software developed for
internal use.  These costs are amortized on a straight-line basis over a
five-year period beginning with a project's completion.

PROPERTY TAXES - Property taxes are accrued monthly during the fiscal period of
the applicable taxing authority.

INCOME TAXES - Deferred income taxes are provided for temporary differences
between book and tax bases of assets or liabilities to the extent authorized by
the MPSC.  For federal income tax purposes, depreciation is computed using
accelerated methods and shorter depreciable lives.  Investment tax credits
utilized which relate to utility property were deferred and are amortized over
the estimated composite service life of the related property.  See Note 6.

ACCRETION INCOME - In 1988, Detroit Edison adopted SFAS No. 90, "Regulated
Enterprises - Accounting for Abandonments and Disallowances of Plant Costs."
As a result, indirect losses were recorded for Greenwood Unit No. 1 for the
period that plant was not allowed in rate base (1988-1993), and for the
indirect loss related to the $300 million of Fermi 2 plant costs recovered from
1989 to 1998 with no return.  The net after-tax losses originally totaled $198
million based on the discounting required by SFAS No. 90.  These amounts are
being restored to income over the respective discount periods as Detroit Edison
records a non-cash return (accretion income).  The net after-tax income
recorded was $5.3 million, $7.2 million and $8.9 million in 1996, 1995 and
1994, respectively.

CAPITALIZATION - DISCOUNT AND EXPENSE - The discount and expense related to the
issuance of long-term debt are amortized over the life of each issue.  In
accordance with MPSC regulations applicable to Detroit Edison, the discount and
expense related to debt redeemed without refunding are written off to other
income and deductions.  Capital stock expense related to redeemed preferred
stock of Detroit Edison is written off against retained earnings used in the
business.

FERMI 2 REFUELING OUTAGES - Detroit Edison recognizes the cost of Fermi 2
refueling outages over periods in which related revenues are recognized.  Under
this procedure, it records a provision for incremental costs anticipated to be
incurred during the next scheduled Fermi 2 refueling outage.  See Note 2.

LEASES - See Note 10.

EMPLOYEE BENEFITS - See Note 13.

STOCK-BASED COMPENSATION - In October 1995, the Financial Accounting Standards
Board ("FASB") issued SFAS No. 123, "Accounting for Stock-Based Compensation,"
effective for 1996.  This statement establishes a fair-value based method of
accounting for stock compensation plans.  As permitted, the Company accounts
for stock-based compensation using the intrinsic value method prescribed in
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees."  See Note 13 for discussion of stock-based compensation as part of
the Long-Term Incentive Plan.

NOTE 2 - FERMI 2
- --------------------------------------------------------------------------------

GENERAL - Fermi 2, a nuclear generating unit, began commercial operation in
January 1988.  Fermi 2 has a design electrical rating (net) of 1,139 megawatts
("MW").  This unit represents approximately 25% of total assets, 10% of total
operation and maintenance expenses and 9% of summer net rated capability.

     MPSC rate orders issued in April 1986, December 1988 and January 1994
contain provisions with respect to the recovery of Fermi 2 costs.  See Note 3
for a discussion of Fermi 2 rate matters and the MPSC's treatment of Fermi 2's
original project costs of $4.858 billion.

LICENSING AND OPERATION - The Nuclear Regulatory Commission ("NRC") maintains
jurisdiction over the licensing and operation of Fermi 2.

     On December 25, 1993, the Fermi 2 reactor automatically shutdown following
a turbine-generator failure.  The turbine suffered mechanical damage, the
exciter and generator incurred mechanical and fire damage, and the condenser
had some internal damage.  Therefore, Fermi 2 was out of service in 1994 and
part of 1995.  The nuclear part of the plant was not damaged.

     Major repairs were completed in 1994 and early 1995 and the unit operated
at a reduced power output through September 26, 1996.  These repair costs were
approximately $80 million for which to date Detroit Edison has received partial
insurance payments of $70 million for property damage.  In addition, Detroit
Edison has received partial insurance payments of $74.2 million for replacement
power costs through December 31, 1996.

     The unit was shut down from September 27, 1996 to January 3, 1997 to
replace one-third of its nuclear fuel and install three new low-pressure
turbines.  With the installation of these new turbines the unit is expected to
initially operate at 1,085 MW, up from 876 MW prior to this shut down.  The $49
million cost of replacing the major turbine components was not covered by
insurance.  This cost was capitalized and is expected to be recovered in rates
because it is less than the cumulative amount available under the cap on Fermi
2 capital expenditures, a provision of the MPSC's December 1988 order.  See
Note 3.

     On January 17, 1997, there was an electrical component failure in the
switchyard outside the plant which resulted in the "motorizing" of the main
generator caused by incoming electricity from the Detroit Edison electrical
system.  As a result, the Fermi 2 plant was shut down to allow 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.  Operation of the reactor was not affected by this
incident.  Although the costs of repairs are expected to be covered by
insurance (subject to a $1 million deductible), this incident will require an
increase in the Fermi 2 capacity factor performance standard reserve for the
period 1997-1999 which will have an adverse effect on earnings in the first
quarter of 1997. See Note 3.

INSURANCE - Detroit Edison insures Fermi 2 with property damage insurance
provided by Nuclear Mutual Limited ("NML") and Nuclear Electric Insurance
Limited ("NEIL").  The NML and NEIL insurance policies provide $500 million of
composite primary coverage (with a $1 million deductible and, effective January
22, 1997, a $10 million deductible for the turbine-generator unit) and $2.25
billion of excess coverage, respectively, for stabilization, decontamination
and debris removal costs, repair and/or replacement of property and
decommissioning.  Accordingly, the combined limits provide total property
damage insurance of $2.75 billion.

     Detroit Edison maintains an insurance policy with NEIL providing for extra
expenses, including certain replacement power costs necessitated by Fermi 2's
unavailability due to an insured event.  This policy, which has a 21-week
waiting period, provides for three years of coverage.

     Under the NML and NEIL policies, Detroit Edison could be liable for
maximum retrospective assessments of up to approximately $28 million per loss
if any one loss should exceed the accumulated funds available to NML or NEIL.

     As required by federal law, Detroit Edison maintains $200 million of
public liability insurance for a nuclear incident.  Further, under the
Price-Anderson Amendments Act of 1988, deferred premium charges of $75.5
million could be levied against each licensed nuclear facility, but not more
than $10 million per year per facility.  On December 31, 1996, there were 110
licensed nuclear facilities in the United States.  Thus, deferred premium
charges in the aggregate amount of approximately $8.3 billion could be levied
against all owners of licensed nuclear facilities in the event of a nuclear
incident.

DECOMMISSIONING - The NRC has jurisdiction over the decommissioning of nuclear
power plants.  An NRC rule requires decommissioning funding based upon a
site-specific estimate or a predetermined NRC formula.  Using the NRC's
formula, plus an additional allowance for decommissioning the non-nuclear
portion of the plant, it is estimated that the cost of decommissioning Fermi 2
when its license expires in the year 2025 is $520 million in current 1996
dollars and $3 billion in future 2025 dollars.  The assumed annual inflation
rate used to increase the cost to decommission is 6%, compounded annually.

     The MPSC and FERC regulate the recovery of costs of decommissioning
nuclear power plants and both require the use of external trust funds to
finance the decommissioning of Fermi 2.  The MPSC's January 1994 order includes
an increase in rates for the decommissioning of Fermi 2.  The FERC has approved
the recovery of decommissioning expense in base rates in its June 1993 order.
Detroit Edison believes that the MPSC and FERC orders will be adequate to fund
the estimated cost of decommissioning using the NRC formula.  See Note 3.

     Detroit Edison has established external trust funds to hold
decommissioning and low-level radioactive waste disposal funds collected from
customers.  During 1996, 1995 and 1994, Detroit Edison collected $33.5 million,
$32.1 million and $26.9 million, respectively, from customers for
decommissioning Fermi 2.  Also, in 1996, 1995 and 1994, Detroit Edison
collected $4.2 million, $4.1 million and $3.3 million, respectively, from
customers for low-level radioactive waste disposal.  Such amounts were recorded
as components of depreciation and amortization expense in the Consolidated
Statement of Income and accumulated depreciation and amortization in the
Consolidated Balance Sheet.  Earnings on the external decommissioning trust
fund assets during 1996, 1995 and 1994 were $4.4 million, $3.3 million and $1.3
million, respectively.  Earnings on the external low-level radioactive waste
disposal trust fund assets were $0.7 million, $0.6 million and $0.2 million in
1996, 1995 and 1994, respectively.  Trust fund earnings are recorded as an
investment with a corresponding credit to accumulated depreciation and
amortization.  Trust fund assets are assumed to earn an after-tax rate of
return of 7%, compounded annually.  In accordance with SFAS No. 115,
"Accounting for Certain Investments in Debt and Equity Securities," net
unrealized gains of $8.7 million, $4.6 million and $0.7 million in 1996, 1995
and 1994,

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

respectively, were recorded as increases to the nuclear
decommissioning trust funds and accumulated depreciation and amortization in
the Consolidated Balance Sheet.

     During 1995, shipment of low-level radioactive waste to a permanent
disposal site resumed.  Detroit Edison's disposal costs of $3.5 million and
$5.7 million during 1996 and 1995, respectively, were reimbursed by the
external trust funds.

     At December 31, 1996, Detroit Edison had a reserve of $138.1 million for
the future decommissioning of Fermi 2 and $11.2 million for low-level
radioactive waste disposal costs.  These reserves are included in accumulated
depreciation and amortization in the Consolidated Balance Sheet with a like
amount deposited in external trust funds.

     Detroit Edison also had a reserve of $22.2 million at December 31, 1996
for the future decommissioning of Fermi 1, an experimental nuclear unit on the
Fermi 2 site that has been shut down since 1972.  This reserve is included in
other deferred credits in the Consolidated Balance Sheet with a like amount
deposited in an external trust fund.  Detroit Edison estimates that the cost of
decommissioning Fermi 1 in the year 2025 is $21 million in current 1996 dollars
and $114 million in future 2025 dollars.

     The FASB is reviewing the accounting for removal costs, including
decommissioning of nuclear power plants.  If current electric utility industry
accounting practices for such decommissioning are changed:  (1) annual
provisions for decommissioning could increase, and (2) the estimated cost for
decommissioning could be recorded as a liability rather than as accumulated
depreciation.

NUCLEAR FUEL DISPOSAL COSTS - Detroit Edison has a contract with the DOE for
the future storage and disposal of spent nuclear fuel from Fermi 2.  Under the
terms of the contract, Detroit Edison makes quarterly payments to the DOE based
upon a fee of 1 mill per kilowatthour applied to the Fermi 2 electricity 
generated and sold.     The spent nuclear fuel disposal cost is included as a
component of Detroit Edison's nuclear fuel expense.  The Federal Nuclear Waste
Policy Act of 1982 provides that in return for this fee the DOE is to provide a
permanent repository for spent nuclear fuel by January 31, 1998 which statutory
obligation was upheld in October 1996 by the United States Court of Appeals for
the District of Columbia Circuit.  Nevertheless, the DOE has indicated it will
be unable to begin acceptance by the required date and has requested comments
from Detroit Edison and other affected companies.  The DOE and utilities with
nuclear units are pursuing other interim storage options.  Detroit Edison
estimates that existing temporary storage capacity at Fermi 2 will be
sufficient until the year 2001, or until 2017 with the expansion of such
storage capacity.

NOTE 3 - REGULATORY MATTERS
- --------------------------------------------------------------------------------

Detroit Edison is subject to the primary regulatory jurisdiction of the MPSC,
which, from time to time, issues its orders pertaining to Detroit Edison's
conditions of service, rates and recovery of certain costs including the costs
of generating facilities.  MPSC orders issued in December 1988 and on January
21, 1994 are currently in effect with respect to Detroit Edison's rates and
certain other revenue and operating-related matters.

     On January 21, 1994, the MPSC issued an order reducing Detroit Edison's
rates in the amount of $78 million annually.  The rate reduction was determined
by using a 1994 test year and an overall rate of return of 7.66%, incorporating
an 11% return on common equity and a capital structure comprised of 40% common
equity, 55.01% long-term debt and 4.99% preferred stock.  The MPSC order
includes the recovery of (1) increased Fermi 2 decommissioning costs of $28.1
million annually, which includes the recovery of low-level radioactive waste
disposal costs, (2) full recovery of 1994 other postretirement benefit costs
plus recovery and amortization of the 1993 deferred cost (see Note 13), (3)
costs associated with the return to rate base of Greenwood Unit No. 1, (4) Fermi
2 phase-in plan revenue requirements of $70.8 million in 1994 and (5) costs
associated with a three-year demand-side management program.  In keeping with
the MPSC's recognition of the need for industrial customers to be competitive,
the January 1994 rate reduction was allocated among the various classes of
customers approximately as follows:  Industrial-$43 million, Commercial-$24
million, Residential-$10 million and Governmental-$1 million. The order is the
subject of various appeals before the Michigan Court of Appeals.

COMMERCIAL AND INDUSTRIAL RATES - Detroit Edison is continuing to address its
competitive status by entering into long-term service contracts with certain of
its large commercial and industrial customers.  These contracts must be approved
by the MPSC prior to implementation.  At December 31, 1996 and 1995 these
contracts accounted for revenues of approximately $299 million and $208 million,
respectively.  While there are revenue reductions associated with these
long-term service contracts, Detroit Edison believes they are strategically
advantageous.

FERMI 2 - The December 1988 MPSC order established, for the period January 1989
through December 2003, (1) a cap on Fermi 2 capital additions of $25 million per
year, in 1988 dollars adjusted by the Consumers Price Index ("CPI"), cumulative,
(2) a cap on Fermi 2 non-fuel operation and maintenance expenses adjusted by the
CPI and (3) a capacity factor performance standard based on a three-year rolling
average commencing in 1991.  For a capital investment of $200 million or more
(in 1988 dollars adjusted by the CPI), Detroit Edison must obtain prior MPSC
approval to be included in rate base.

     Under the cap on Fermi 2 capital expenditures, the cumulative amount
available totals $47 million (in 1996 dollars) at December 31, 1996.  Under the
cap on non-fuel operation and maintenance expenses, the cumulative amount
available totals $69 million (in 1996 dollars) at December 31, 1996.

     Under the capacity factor performance standard, a disallowance of net
incremental replacement power cost will be imposed for the amount by which the
Fermi 2 three-year rolling average capacity factor is less than the greater of
either the average of the top 50% of U.S. boiling water reactors or 50%.  For
purposes of the capacity factor performance standard, the capacity for Fermi 2
for the period 1989-1993 shall be 1,093 MW, and 1,139 MW for each year
thereafter until December 31, 2003.

     As discussed in Note 2, Fermi 2 was out of service in 1994 and part of
1995, and operated at a reduced power output during 1995 and 1996.  Therefore,
the three-year rolling average capacity factor utilized in the Fermi 2
performance standard calculation will be unfavorably affected in the period
1994-1998.  The plant's three-year rolling average capacity factor was 53.7% for
1994, 45.4% for 1995 and 33.1% for 1996, utilizing a capacity of 1,093 MW for
1992 and 1993 and 1,139 MW for 1994, 1995 and 1996.  The three-year rolling


                                      52
<PAGE>   55

average capacity factor for the top 50% of U.S. boiling water reactors was 78.6%
for 1994 and 81.8% for 1995.

     Detroit Edison incurred a capacity factor disallowance totaling $19.2
million for 1994.  In accordance with an MPSC order, three times this amount was
used to determine the net refund to customers in the 1994 PSCR reconciliation
case, resulting in banked credits of $38.5 million which will reduce future
capacity factor disallowance amounts owing to customers.  The capacity factor
disallowance for 1995 has not yet been determined by the MPSC. At December 31,
1996, Detroit Edison had accrued $56.8 million (capacity factor disallowances of
$95.3 million, less banked credits of $38.5 million) for the Fermi 2 capacity
factor performance standard disallowances that are expected to be imposed by the
MPSC during the period 1995-1998, based on the following assumptions:

    a.   Fermi 2 three-year rolling average capacity factor of 45.4% in
         1995, 33.1% in 1996, and an estimated 61.7% in 1997 and 71.1% in 1998;

    b.   Estimated three-year rolling average capacity factor for the top
         50% of U.S. boiling water reactors of 81.8% in 1995 and increasing to
         84% in 1998;

    c.   Estimated incremental cost of replacement power of $7.61 per
         megawatthour in 1995 and increasing to $11 per megawatthour in 1998.

     See Note 2 for information on the current Fermi 2 shutdown.

     Also, Detroit Edison has recorded an additional liability of $16 million at
December 31, 1996 for reduced efficiency of the Fermi 2 turbine in 1995 and 1996
when the unit operated at a reduced power output.

     In accordance with the April 1986 and December 1988 MPSC rate orders,
ratemaking treatment of Detroit Edison's Fermi 2 original project costs of
$4.858 billion is as follows:  (1) $3.018 billion in rate base with recovery and
return, (2) $300 million amortized over 10 years with no return, (3) $513
million amortized over 19 years with associated interest of 8% and (4) $1.027
billion disallowed and written off in 1988.

     At December 31, 1996, Detroit Edison's net plant investment in Fermi 2 was
$2.8 billion ($3.9 billion less accumulated depreciation and amortization of
$1.1 billion).

     Under the December 1988 MPSC order, if nuclear operations at Fermi 2
permanently cease, amortization in rates of the $300 million and $513 million
investments in Fermi 2 would continue and the remaining net rate base investment
amount shall be removed from rate base and amortized in rates, without return,
over 10 years with such amortization not to exceed $290 million per year.  In
this event, unamortized amounts of deferred depreciation and deferred return,
recorded in the Consolidated Balance Sheet under the phase-in plan prior to the
removal of Fermi 2 from rate base, will continue to be amortized, with a full
return on such unamortized balances, so that all amounts deferred are recovered
during the period ending no later than December 31, 1998.  The December 1988 and
January 1994 rate orders do not address the costs of decommissioning if
operations at Fermi 2 prematurely cease.

     Detroit Edison has and believes it will continue to operate under the terms
of all applicable MPSC orders with no significant adverse effects as a result of
any cost recovery restrictions contained therein.

* The Detroit Edison income tax expense for 1996 was $224,999.


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

     The Fermi 2 phase-in plan required Detroit Edison to record additional
deferred income tax expense related to deferred depreciation totaling $33.5
million, with this amount amortized to income over the six-year period ending
December 31, 1998.

     With the adoption of SFAS 109, "Accounting for Income Taxes" in 1993, an
increase in accumulated deferred income tax liabilities was recorded which
represented the tax effect of temporary differences not previously recognized,
and the recomputation of the tax liability at the current tax rate.  The
liability increase was offset by a regulatory asset of equal value, titled
"Recoverable Income Taxes."  This regulatory asset represents the future
revenue recovery from customers for these taxes as they become payable, with no
effect on net income.  The MPSC issued an order providing assurance that the
effects of previously flowed-through tax benefits will continue to be allowed
rate recovery.

Deferred income tax assets (liabilities) are comprised of the following at
December 31:

which covers substantially all of Detroit Edison's properties, provides for
the issuance of additional bonds. At December 31, 1996, approximately $3.4
billion principal amount of Mortgage Bonds could have been issued on the basis
of property additions, combined with an earnings test provision, assuming an
interest rate of 8% on any such additional Mortgage Bonds.  An additional $1.2
billion principal amount of Mortgage Bonds could have been issued on the basis
of bond retirements.

 * Weighted average interest rate at December 31, 1996.
** Variable rate at December 31, 1996.

     Each series of QUIDS provides that interest will be payable quarterly
provided that, so long as an event of default has not occurred and is not
continuing with respect to such series of QUIDS, Detroit Edison will have the
right, upon prior notice by public announcement given in accordance with New
York Stock Exchange rules, to extend the interest payment period at any time
and from time to time on the QUIDS for up to 20 consecutive quarterly interest
payment periods.  As a consequence, quarterly interest payments on the
applicable series of QUIDS would be deferred but would continue to accrue
interest during any deferral period.  In the event that Detroit Edison
exercises this right, Detroit Edison may not declare or pay dividends on,
or redeem, purchase or acquire, any of its capital stock during such deferral
period, other than redemptions of any series of capital stock of Detroit Edison
pursuant to the terms of any sinking fund provisions with respect thereto.  In
addition, during any deferral period, Detroit Edison may not make any advance
or loan to, or purchase any securities of, or make any other investment in, any
affiliate of Detroit Edison, including DTE Energy Company, for the purpose of,
or to enable the payment of, directly or indirectly, dividends on any equity
securities of DTE Energy Company.

     A non-recourse project financing arrangement is in place for PCI
Enterprises borrowings of up to $50 million, of which $38.9 million was
outstanding at December 31, 1996.  This arrangement is collateralized by
specific project assets.  This

construction period financing will be converted into a seven-year, variable
rate, term loan at the construction loan maturity date of October 31, 1997. 
The expected maturities of this term loan for 1997, 1998, 1999, 2000 and
2001 consist of $1.5 million, $3.3 million, $3.2 million, $2.8 million and $2.5
million, respectively.

     In October 1996, Detroit Edison entered into a three-year interest rate
swap agreement based on a notional amount of $25 million.  Detroit Edison will
receive a rate equal to the London Interbank Offered Rate and pay a rate equal
to the quarterly weighted average Public Securities Association Municipal Swap
Index divided by 67.3%.  The intent of the swap is to shift floating rate
exposure from the taxable markets to the tax-exempt markets.  As of December
31, 1996 the average rate received was 5.53% and the average rate paid was
5.08%.  The swap is subject to market risk of changes in both interest rates
and tax rates.  Detroit Edison does not believe changes in either or both rates
will have a material effect on interest expense.

     In 1997, 1998, 1999, 2000 and 2001, Detroit Edison's long-term debt
maturities consist of $144 million, $169 million, $219 million, $194 million
and $119 million, respectively.

NOTE 9 - SHORT-TERM CREDIT ARRANGEMENTS AND BORROWINGS
- --------------------------------------------------------------------------------
At December 31, 1996, Detroit Edison had total short-term credit arrangements
of approximately $464 million.  At December 31, 1996 and December 31, 1995, $10
million and $37 million, respectively, of short-term borrowings were
outstanding.  The weighted average interest rates for short-term borrowings
during 1996, 1995 and 1994 were 5.6%, 6.1% and 4.3%.

     Detroit Edison had bank lines of credit of $200 million, all of which had
commitment fees in lieu of compensating balances.  Commitment fees incurred in
1996 and 1995 for bank lines of credit were approximately $0.3 million.
Detroit Edison uses bank lines of credit to support the issuance of commercial
paper and bank loans.  All borrowings are at prevailing money market rates
which are below the banks' prime lending rates.

     Detroit Edison has a nuclear fuel financing arrangement (heat purchase
contract) with Renaissance Energy Company ("Renaissance"), an unaffiliated
company.  Renaissance may issue commercial paper or borrow from participating
banks on the basis of promissory notes.  To the extent the maximum amount of
funds available to Renaissance (currently $400 million) is not needed by
Renaissance to purchase nuclear fuel, such funds may be loaned to Detroit
Edison for general corporate purposes pursuant to a separate Loan Agreement.
At  December 31, 1996, approximately $264 million was available to Detroit
Edison under such Loan Agreement.  See Note 10 for a discussion of Detroit
Edison's heat purchase contract with Renaissance.

     At December 31, 1996, DTE Capital Corporation had a $200 million Revolving
Credit Agreement, backed by a Support Agreement from the Company, under which
no borrowings were outstanding.  Commitment fees incurred in 1996 for this
credit agreement were approximately $0.3 million.

NOTE 10 - LEASES

Future minimum lease payments under long-term noncancellable leases, consisting
of nuclear fuel ($148 million computed on a projected units of production
basis), lake vessels ($36 million), locomotives and coal cars ($152 million),
office space ($16 million), and computers, vehicles and other equipment ($3
million) at December 31, 1996 are as follows:

</TABLE>

     Detroit Edison has a heat purchase contract with Renaissance which
provides for the purchase by Renaissance for Detroit Edison of up to $400
million of nuclear fuel, subject to the continued availability of funds to
Renaissance to purchase such fuel.  Title to the nuclear fuel is held by
Renaissance.  Detroit Edison makes quarterly payments under the heat purchase
contract based on the consumption of nuclear fuel for the generation of
electricity.  Renaissance's investment in nuclear fuel was $134 million and
$145 million at December 31, 1996 and 1995, respectively.  The decrease in 1996
from 1995 of $11 million includes additions of $35 million (purchases of $33
million and capitalized interest of $2 million) less $46 million for the
amortization of nuclear fuel consumed in 1996.

     Under SFAS No. 71, amortization of Detroit Edison's leased assets is
modified so that the total of interest on the obligation and amortization of
the leased asset is equal to the rental expense allowed for ratemaking
purposes.  For ratemaking purposes, the MPSC has treated all leases as
operating leases.  Net income is not affected by capitalization of leases.

     Rental expenses for both capital and operating leases were $78 million
(including $53 million for nuclear fuel), $97 million (including $67 million
for nuclear fuel) and $49 million (including $8 million for nuclear fuel) for
1996, 1995 and 1994, respectively.

NOTE 11 - FAIR VALUE OF FINANCIAL INSTRUMENTS
- --------------------------------------------------------------------------------
The fair value of financial instruments is determined by reference to various
market data and other valuation techniques as appropriate.  The carrying amount
of financial instruments, except for long-term debt, approximates fair value.
The estimated fair value of total long-term debt at December 31, 1996 and 1995
was $4 billion and $4.1 billion, respectively, compared to the carrying amount
of $3.9 billion for each of the two years.  For purposes of applying SFAS No.
115, "Accounting for Certain Investments in Debt and Equity Securities",
investments in debt and equity securities are classified as "available for
sale."

NOTE 12 - COMMITMENTS AND CONTINGENCIES
- --------------------------------------------------------------------------------
COMMITMENTS - Detroit Edison has entered into purchase commitments of
approximately $633 million at December 31, 1996, which includes, among other
things, line construction and 




                                      56

clearance costs.  Detroit Edison also has entered into substantial long-term
fuel supply and transportation commitments. 

     Detroit Edison has an Energy Purchase Agreement ("Agreement") for the
purchase of steam and electricity from the Detroit Resource Recovery Facility.
Under the Agreement, Detroit Edison will purchase steam through the year 2008
and electricity through June 30, 2024.  Purchases of steam and electricity were
$30.2 million, $28.2 million and $24.5 million for 1996, 1995 and 1994,
respectively, and annual purchase commitments are approximately $35 million,
$36 million, $37 million, $39 million and $40 million for 1997, 1998, 1999,
2000 and 2001, respectively.  See Note 14 relating to steam heating special
charges.

     On October 25, 1995, the MPSC issued an order approving Detroit Edison's
long-term capacity and energy purchase agreement from Ontario Hydro. The
purchase is for 300 MW, on a seasonal basis from mid-May through mid-September
for the years 1996 through 2001.  This purchase will offset a concomitant
agreement to lease 312 MW of Detroit Edison's 917 MW Ludington capacity
entitlement to the Toledo Edison Company for essentially the same time period.
The net economic effect of the Ludington lease and the Ontario Hydro purchase
will be to provide Detroit Edison's customers with an estimated reduction in
PSCR expense of $74 million which will be passed through to customers through
the PSCR clause.

CONTINGENCIES - LEGAL PROCEEDINGS - On May 28, 1996, an order was issued by the
Circuit Court for Wayne County, Michigan certifying a plaintiff class (Gilford,
et al v Detroit Edison) in a lawsuit claiming that Detroit Edison had engaged
in age and racial discrimination.  Detroit Edison has requested leave to appeal
the class certification to the Michigan Supreme Court and has requested a stay
of proceedings.  A notice has been sent to potential class members, however,
the size of the potential class will not be determinable until late May 1997 at
the earliest.  Detroit Edison is of the opinion that the allegations of
discrimination are without merit.

     CARTER INDUSTRIALS - In January 1989, the Environmental Protection Agency
("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.  In June 1993, a Consent Decree was entered by the
U.S. District Court for the Eastern District of Michigan.  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 outfall emptying into the Detroit
River began in August 1996 and was completed in November 1996.  It is expected
the site will soon be removed from the National Priorities List.

     OTHER - In addition to the matters reported herein, the Company and its
subsidiaries are involved in litigation and environmental matters dealing with
the numerous aspects of their business operations.  The Company believes that
such litigation and the matters discussed above will not have a material effect
on its financial position, results of operations and cash flows.

     See Notes 2 and 3 for a discussion of contingencies related to Fermi 2.

NOTE 13 - EMPLOYEE BENEFITS
- --------------------------------------------------------------------------------
RETIREMENT PLAN - Detroit Edison has a trusteed and non-contributory defined
benefit retirement plan ("Plan") covering all eligible employees who have
completed six months of service.  The Plan provides retirement benefits based
on the employees' years of benefit service, average final compensation and age
at retirement.  Detroit Edison's policy is to fund pension cost calculated
under the projected unit credit actuarial cost method, provided that this
amount is at least equal to the minimum funding requirement of the Employee
Retirement Income Security Act of 1974, as amended, and is not greater than the
maximum amount deductible for federal income tax purposes.  Contributions were
made to the Plan totaling $16 million, $29.6 million and $45.8 million for
1996, 1995 and 1994, respectively.

     Net pension cost included the following components:

     The unrecognized net asset at date of initial application is being
amortized over approximately 15.4 years, which was the average remaining
service period of employees at January 1, 1987.

     In addition to the Plan, there are several supplemental non-qualified,
non-contributory, retirement benefit plans for certain management employees.

LONG-TERM INCENTIVE PLAN - The Company has adopted a long-term incentive plan
("Incentive Plan").  Under the Incentive Plan, certain key employees may be
granted stock options, stock appreciation rights, restricted common stock,      
performance shares and performance units.  In 1996 and 1995, 56,000 shares and
66,500 shares, respectively, of restricted common stock, valued at
approximately $3.8 million, were conditionally granted to officers of Detroit
Edison.  Compensation cost of $1,165,000 and $571,000 in 1996 and 1995,
respectively, was recorded based on the award that was expected to vest and
recognized over the period to which the related employee services were to be
rendered.  The shares for officers are restricted for a period not exceeding
four years and all shares are subject to forfeiture if specified performance
measures are not met.  There are no exercise prices related to these shares. 
During the applicable restriction period, the officer-recipient has all the
voting, dividends and other rights of a record holder except that the shares
are nontransferable, and non-cash distributions paid upon the shares would be
subject to transfer restrictions and risk of forfeiture to the same extent as
the shares themselves.  Based upon performance under the 1995 plan 12,192
shares were forfeited.  All shares awarded pursuant to this program were
purchased on the open market.  Common stock granted under the Incentive Plan
may not exceed 7.2 million shares. Performance units (which have a face amount
of $1) granted under the Incentive Plan may not exceed 25 million in the
aggregate.  No stock options, stock appreciation rights, performance shares or
performance units have been granted under this plan.  Disclosures required by
SFAS No. 123 have been omitted because such amounts are considered immaterial.

SAVINGS & INVESTMENT PLANS - Detroit Edison has contributory defined
contribution plans qualified under Section 401 (a) and (k) of the Internal
Revenue Code for all eligible employees.  Matching contributions were $17.2
million, $13.7 million and $12.5 million for 1996, 1995 and 1994, respectively.

OTHER POSTRETIREMENT BENEFITS - Detroit Edison provides certain postretirement
health care and life insurance benefits for retired employees.  Substantially
all of Detroit Edison's  employees will become eligible for such benefits if
they reach retirement age while working for Detroit Edison.  These benefits are
provided principally through insurance companies and other organizations.

     Effective January 1, 1993, Detroit Edison adopted the provisions of SFAS
No. 106, "Employers' Accounting for Postretirement Benefits Other Than
Pensions."  The standard required Detroit Edison to change its accounting for
postretirement benefits from the pay-as-you-go (cash) basis to the accrual of
such benefits during the active service periods of employees to the date they
attain full eligibility for benefits.  The transition obligation at the time of
adoption is being amortized over 20 years.  Detroit Edison's incremental cost
upon adoption of the standard was $49 million for 1993 which was deferred in
accordance with the January 21, 1994 MPSC rate order.  See Note 3.  This amount
is being amortized and recovered in rates over the four-year period 1994-1997.

     Net other postretirement benefits cost included the following components:

Benefit costs were calculated assuming health care cost trend rates beginning
at 10.5% for 1996 and decreasing to 5.5% in 2008 and thereafter for persons
under age 65 and decreasing from 6.5% to 5.5% for persons age 65 and over.  A
one-percentage-point increase in health care cost trend rates would increase
the aggregate of the service cost and interest cost components of benefit costs
by $9 million for 1996 and increase the accumulated benefit obligation by $76
million at December 31, 1996.

NOTE 14 - STEAM HEATING SPECIAL CHARGES
- --------------------------------------------------------------------------------

     The Company adopted SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of," in the fourth
quarter of 1995.  As the result of continuing losses in the operation of its
steam heating business, upon adoption of SFAS No. 121, Detroit Edison wrote off
the remaining net book value of its steam heating plant assets of $42 million
($32 million after-tax) or $0.22 per share in 1995.

     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 ($97 million after-tax) or $0.67 per share. The
special charge included a reserve for steam purchase commitments during the
period from 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 system and improvements in service to remaining customers.  See
Note 12.

     The reserve for steam purchase commitments was recorded at its present
value of $134 million at December 31, 1996, using a risk free discount rate of
6.9%, and is included in Other Deferred Credits in the Consolidated Balance
Sheet.  Therefore, Detroit Edison will record non-cash accretion expense during
the period 1997-2008.

     The third quarter of 1996 includes the steam heating special charge to net
income of $149.2 million ($97 million after-tax) or $0.67 per share.  See
Note 14.

     The fourth quarter of 1996 includes a provision for Fermi 2 capacity
factor disallowances in the period 1996-1998 and for reduced efficiency of the
Fermi 2 turbine in 1995 and 1996 of $20 million ($13 million after-tax) or
$0.09 per share.  See Note 3.

     The fourth quarter of 1995 includes the write-off of the remaining net
book value of Detroit Edison's steam heating plant assets when the Company
adopted SFAS No. 121.  This resulted in a non-cash loss of $42 million ($32
million after-tax) or $0.22 per share.  See Note 14.

     Earnings per share amounts for each quarter are required to be computed
independently and, therefore, may not equal the amount computed for the total
year.

ITEM 9 - CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
         FINANCIAL DISCLOSURE.

     The Board of Directors, upon the recommendation of the Board's Audit
Committee, appointed Deloitte & Touche LLP as independent accountants for the
years 1995 and 1996.  The appointments were ratified by the Common Stock
Shareholders at the Annual Meetings of Common Stock Shareholders held on April
24, 1995 and April 22, 1996, respectively.  Deloitte & Touche LLP's report on
the financial statements for the years ending December 31, 1995 and 1996 did
not contain an adverse opinion or a disclaimer of opinion, nor was it qualified
or modified as to uncertainty, audit scope or accounting principles.

     In prior years, Price Waterhouse LLP served as independent accountants of
the Company.  During the Company's fiscal year ending December 31, 1994, there
were no disagreements with Price Waterhouse LLP on any matter of accounting
principles or practices, financial statement disclosure, or auditing scope or
procedure, which, if not resolved to its satisfaction, would have caused Price
Waterhouse LLP to make reference thereto in their report on the financial
statements for such year.  Price Waterhouse LLP's report on the financial
statements for the year ended December 31, 1994 did not contain an adverse
opinion or a disclaimer of opinion, nor was it qualified or modified as to
uncertainty, audit scope or accounting principles.

                    definitive bonds of Series KKP No. 12, but with such
                    omissions, insertions and variations as may be appropriate
                    for temporary bonds, all as may be determined by the
                    Company.

                      Bonds of Series KKP No. 12 shall not be assignable or
                    transferable except as may be required to effect a transfer
                    to any successor trustee under the Monroe Trust Indenture,
                    or, subject to compliance with applicable law, as may be
                    involved in the course of the exercise of rights and
                    remedies consequent upon an Event of Default under the
                    Monroe Trust Indenture. Any such transfer shall be made upon
                    surrender thereof for cancellation at the office or agency

                    or by its duly authorized attorney. Bonds of Series KKP No.
                    12 shall in the same manner be exchangeable for a like
                    aggregate principal amount of bonds of Series KKP No. 12
                    upon the terms and conditions specified herein and in
                    Section 7 of Article II of the Indenture. The Company waives
                    its rights under Section 7 of Article II of the Indenture
                    not to make exchanges or transfers of bonds of Series KKP
                    No. 12, during any period of ten days next preceding any
                    redemption date for such bonds.

                    form, may bear such legends as may be necessary to comply

                           [FORM OF REVERSE OF BOND]
 
                    This bond is one of an authorized issue of bonds of the
                  Company, unlimited as to amount except as provided in the
                  Indenture hereinafter mentioned or any indentures
                  supplemental thereto, and is one of a series of General and
                  Refunding Mortgage Bonds known as Series KKP No. 12, limited
                  to an aggregate principal amount of $50,745,000, except as
                  otherwise provided in the Indenture hereinafter mentioned.
                  This bond and all other bonds of said series are issued and
                  to be issued under, and are all equally and ratably secured
                  (except insofar as any sinking, amortization, improvement or
                  analogous fund, established in accordance with the
                  provisions of the Indenture hereinafter mentioned, may
                  afford additional security for the bonds of any particular
                  series and except as provided in Section 3 of Article VI of
                  said Indenture) by an Indenture, dated as of October 1,
                  1924, duly executed by the Company to Bankers Trust Company,
                  a corporation of the State of New York, as Trustee, to which
                  Indenture and all indentures supplemental thereto (including
                  the Supplemental Indenture dated as of November 1, 1990)
                  reference is hereby made for a description of the properties
                  and franchises mortgaged and conveyed, the nature and extent
                  of the security, the terms and conditions upon which the
                  bonds are issued and under which additional bonds may be
                  issued, and the rights of the holders of the bonds and of
                  the Trustee in respect of such security (which Indenture and
                  all indentures supplemental thereto, including the
                  Supplemental Indenture dated as of November 1, 1990, are
                  hereinafter collectively called the "Indenture"). As
                  provided in the Indenture, said bonds may be for various
                  principal sums and are issuable in series, which may mature
                  at different times, may bear interest at different rates and
                  may otherwise vary as in said Indenture provided. With the
                  consent of the Company and to the extent permitted by and as
                  provided in the Indenture, the rights and obligations of the
                  Company and of the holders of the bonds and the terms and
                  provisions of the Indenture, or of any indenture
                  supplemental thereto, may be modified or altered in certain
                  respects by affirmative vote of at least eighty-five percent
                  (85%) in amount of the bonds then outstanding, and, if the
                  rights of one or more, but less than all, series of bonds
                  then outstanding are to be affected by the action proposed
                  to be taken, then also by affirmative vote of at least
                  eighty-five percent (85%) in amount of the series of bonds
                  so to be affected (excluding in every instance bonds
                  disqualified from voting by reason of the Company's interest
                  therein as specified in the Indenture); provided, however,
                  that, without the consent of the holder hereof, no such
                  modification or alteration shall, among other things, affect
                  the terms of payment of the principal of or the interest on
                  this bond, which in those respects is unconditional.

                    The holders of the bonds of Series KKP No. 12, by their
                  acceptance of and holding thereof, consent and agree that
                  bonds of any series may be issued which mature on a date or
                  dates later than October 1, 2024 and also consent to the
                  deletion from the first paragraph of Section 5 of Article II
                  of the Indenture of the phrase "but in no event later than
                  October 1, 2024,". Such holders further agree that (a) such
                  consent shall, for all purposes of Article XV of the
                  Indenture and without further action on the part of such
                  holders, be deemed the affirmative vote of such holders at
                  any meeting called pursuant to said Article XV for the
                  purpose of approving such deletion, and (b) such deletion
                  shall become effective at such time as not less than
                  eighty-five per cent (85%) in principal amount of bonds
                  outstanding under the Indenture shall have consented thereto
                  substantially in the manner set forth in Section 4 of Part I
                  of the Supplemental Indenture dated as of November 1, 1990,
                  or in writing, or by affirmative vote cast at a meeting
                  called pursuant to said Article XV, or by any combination
                  thereof.

                    This bond is redeemable upon the terms and conditions set
                  forth in the Indenture, including provision for redemption
                  upon demand of the Monroe Trust Indenture Trustee following
                  the occurrence of an Event of Default under the Monroe Trust
                  Indenture and the acceleration of the principal of the
                  Monroe Revenue Bonds.

                    Under the Indenture, funds may be deposited with the
                  Trustee (which shall have become available for payment), in
                  advance of the redemption date of any of the bonds of Series
                  KKP No. 12 (or portions thereof), in trust for the
                  redemption of such bonds (or portions thereof) and the
                  interest due or to become due thereon, and thereupon all
                  obligations of the Company in respect of such bonds (or
                  portions thereof) so to be redeemed and such interest shall
                  cease and be discharged, and the holders thereof shall
                  thereafter be restricted exclusively to such funds for any
                  and all claims of whatsoever nature on their part under the
                  Indenture or with respect to such bonds (or portions
                  thereof) and interest.

                    In case an event of default, as defined in the Indenture,
                  shall occur, the principal of all the bonds issued
                  thereunder may become or be declared due and payable, in the
                  manner, with the effect and subject to the conditions
                  provided in the Indenture.

                    Upon payment of the principal of, or premium, if any, or
                  interest on, the Monroe Revenue Bonds, whether at maturity
                  or prior to maturity by redemption or otherwise or upon
                  provision for the payment thereof having been made in
                  accordance with Article IX of the Monroe Trust Indenture,
                  bonds of Series KKP No. 12 in a principal amount equal to
                  the principal amount of such Monroe Revenue Bonds and having
                  both a corresponding maturity date and interest rate shall,
                  to the extent of such payment of principal, premium or
                  interest, be deemed fully paid and the obligation of the
                  Company thereunder to make such payment shall forthwith
                  cease and be discharged, and, in the case of the payment of
                  principal and premium, if any, such bonds of said series
                  shall be surrendered for cancellation or presented for
                  appropriate notation to the Trustee.

                    This bond is not assignable or transferable except as may
                  be required to effect a transfer to any successor trustee
                  under the Monroe Trust Indenture, or, subject to compliance
                  with applicable law, as may be involved in the course of the
                  exercise of rights and remedies consequent upon an Event of
                  Default under the Monroe Trust Indenture. Any such transfer
                  shall be made by the registered holder hereof, in person or
                  by his attorney duly authorized in writing, on the books of
                  the Company kept at its office or agency in the Borough of
                  Manhattan, The City and State of New York, upon surrender
                  and cancellation of this bond, and thereupon, a new
                  registered bond of the same series of authorized
                  denominations for a like aggregate principal amount will be
                  issued to the transferee in exchange therefor, and this bond
                  with others in like form may in like manner be exchanged for
                  one or more new bonds of the same series of other authorized
                  denominations, but of the same aggregate principal amount,
                  all as provided and upon the terms and conditions set forth
                  in the Indenture, and upon payment, in any event, of the
                  charges prescribed in the Indenture.

                    No recourse shall be had for the payment of the principal
                  of or the interest on this bond, or for any claim based
                  hereon or otherwise in respect hereof or of the Indenture,
                  or of any indenture supplemental thereto, against any
                  incorporator, or against any past, present or future
                  stockholder, director or officer, as such, of the Company,
                  or of any predecessor or successor corporation, either
                  directly or through the Company or any such predecessor or
                  successor corporation, whether for amounts unpaid on stock
                  subscriptions or by virtue of any constitution, statute or
                  rule of law, or by the enforcement of any assessment or
                  penalty or otherwise howsoever; all such liability being, by
                  the acceptance hereof and as part of the consideration for
                  the issue hereof, expressly waived and released by every
                  holder or owner hereof, as more fully provided in the
                  Indenture.

                           [FORM OF REVERSE OF BOND]
 
                  This bond is one of an authorized issue of bonds of the
                Company, unlimited as to amount except as provided in the
                Indenture hereinafter mentioned or any indentures
                supplemental thereto, and is one of a series of General and
                Refunding Mortgage Bonds known as 1991 Series BP, limited to
                an aggregate principal amount of $25,910,000, except as
                otherwise provided in the Indenture hereinafter mentioned.
                This bond and all other bonds of said series are issued and
                to be issued under, and are all equally and ratably secured
                (except insofar as any sinking, amortization, improvement or
                analogous fund, established in accordance with the
                provisions of the Indenture hereinafter mentioned, may
                afford additional security for the bonds of any particular
                series and except as provided in Section 3 of Article VI of
                said Indenture) by an Indenture, dated as of October 1,
                1924, duly executed by the Company to Bankers Trust Company,
                a corporation of the State of New York, as Trustee, to which
                Indenture and all indentures supplemental thereto (including
                the Supplemental Indenture dated as of May 1, 1991)
                reference is hereby made for a description of the properties
                and franchises mortgaged and conveyed, the nature and extent
                of the security, the terms and conditions upon which the
                bonds are issued and under which additional bonds may be
                issued, and the rights of the holders of the bonds and of
                the Trustee in respect of such security (which Indenture and
                all indentures supplemental thereto, including the
                Supplemental Indenture dated as of May 1, 1991, are
                hereinafter collectively called the "Indenture"). As
                provided in the Indenture, said bonds may be for various
                principal sums and are issuable in series, which may mature
                at different times, may bear interest at different rates and
                may otherwise vary as in said Indenture provided. With the
                consent of the Company and to the extent permitted by and as
                provided in the Indenture, the rights and obligations of the
                Company and of the holders of the bonds and the terms and
                provisions of the Indenture, or of any indenture
                supplemental thereto, may be modified or altered in certain
                respects by affirmative vote of at least eighty-five percent
                (85%) in amount of the bonds then outstanding, and, if the
                rights of one or more, but less than all, series of bonds
                then outstanding are to be affected by the action proposed
                to be taken, then also by affirmative vote of at least
                eighty-five percent (85%) in amount of the series of bonds
                so to be affected (excluding in every instance bonds
                disqualified from voting by reason of the Company's interest
                therein as specified in the Indenture); provided, however,
                that, without the consent of the holder hereof, no such
                modification or alteration shall, among other things, affect
                the terms of payment of the principal of or the interest on
                this bond, which in those respects is unconditional.

                  The holders of the bonds of 1991 Series BP, by their
                acceptance of and holding thereof, consent and agree that
                bonds of any series may be issued which mature on a date or
                dates later than October 1, 2024 and also consent to the
                deletion from the first paragraph of Section 5 of Article II
                of the Indenture of the phrase "but in no event later than
                October 1, 2024,". Such holders further agree that (a) such
                consent shall, for all purposes of Article XV of the
                Indenture and without further action on the part of such
                holders, be deemed the affirmative vote of such holders at
                any meeting called pursuant to said Article XV for the
                purpose of approving such deletion, and (b) such deletion
                shall become effective at such time as not less than
                eighty-five per cent (85%) in principal amount of bonds
                outstanding under the Indenture shall have consented thereto
                substantially in the manner set forth in Section 4 of Part I
                of the Supplemental Indenture dated as of May 1, 1991, or in
                writing, or by affirmative vote cast at a meeting called
                pursuant to said Article XV, or by any combination thereof.

                  This bond is redeemable upon the terms and conditions set
                forth in the Indenture, including provision for redemption
                upon demand of the Strategic Fund Trust Indenture Trustee
                following the occurrence of an Event of Default under the
                Strategic Fund Trust Indenture and the acceleration of the
                principal of the Strategic Fund Revenue Bonds.

                   Under the Indenture, funds may be deposited with the
                 Trustee (which shall have become available for payment), in
                 advance of the redemption date of any of the bonds of 1991
                 Series BP (or portions thereof), in trust for the redemption
                 of such bonds (or portions thereof) and the interest due or
                 to become due thereon, and thereupon all obligations of the
                 Company in respect of such bonds (or portions thereof) so to
                 be redeemed and such interest shall cease and be discharged,
                 and the holders thereof shall thereafter be restricted
                 exclusively to such funds for any and all claims of
                 whatsoever nature on their part under the Indenture or with
                 respect to such bonds (or portions thereof) and interest.

                   In case an event of default, as defined in the Indenture,
                 shall occur, the principal of all the bonds issued
                 thereunder may become or be declared due and payable, in the
                 manner, with the effect and subject to the conditions
                 provided in the Indenture.

                   Upon payment of the principal of, or premium, if any, or
                 interest on, the Strategic Fund Revenue Bonds, whether at
                 maturity or prior to maturity by redemption or otherwise or
                 upon provision for the payment thereof having been made in
                 accordance with Article IV of the Strategic Fund Trust
                 Indenture, bonds of 1991 Series BP in a principal amount
                 equal to the principal amount of such Strategic Fund Revenue
                 Bonds and having both a corresponding maturity date and
                 interest rate shall, to the extent of such payment of
                 principal, premium or interest, be deemed fully paid and the
                 obligation of the Company thereunder to make such payment
                 shall forthwith cease and be discharged, and, in the case of
                 the payment of principal and premium, if any, such bonds of
                 said series shall be surrendered for cancellation or
                 presented for appropriate notation to the Trustee.

                   This bond is not assignable or transferable except as may
                 be required to effect a transfer to any successor trustee
                 under the Strategic Fund Trust Indenture, or, subject to
                 compliance with applicable law, as may be involved in the
                 course of the exercise of rights and remedies consequent
                 upon an Event of Default under the Strategic Fund Trust
                 Indenture. Any such transfer shall be made by the registered
                 holder hereof, in person or by his attorney duly authorized
                 in writing, on the books of the Company kept at its office
                 or agency in the Borough of Manhattan, The City and State of
                 New York, upon surrender and cancellation of this bond, and
                 thereupon, a new registered bond of the same series of
                 authorized denominations for a like aggregate principal
                 amount will be issued to the transferee in exchange
                 therefor, and this bond with others in like form may in like
                 manner be exchanged for one or more new bonds of the same
                 series of other authorized denominations, but of the same
                 aggregate principal amount, all as provided and upon the
                 terms and conditions set forth in the Indenture, and upon
                 payment, in any event, of the charges prescribed in the
                 Indenture.

                   No recourse shall be had for the payment of the principal
                 of or the interest on this bond, or for any claim based
                 hereon or otherwise in respect hereof or of the Indenture,
                 or of any indenture supplemental thereto, against any
                 incorporator, or against any past, present or future
                 stockholder, director or officer, as such, of the Company,
                 or of any predecessor or successor corporation, either
                 directly or through the Company or any such predecessor or
                 successor corporation, whether for amounts unpaid on stock
                 subscriptions or by virtue of any constitution, statute or
                 rule of law, or by the enforcement of any assessment or
                 penalty or otherwise howsoever; all such liability being, by
                 the acceptance hereof and as part of the consideration for
                 the issue hereof, expressly waived and released by every
                 holder or owner hereof, as more fully provided in the
                 Indenture.

                           [FORM OF REVERSE OF BOND]

                    This bond is one of an authorized issue of bonds of the
                  Company, unlimited as to amount except as provided in the
                  Indenture hereinafter mentioned or any indentures
                  supplemental thereto, and is one of a series of General and
                  Refunding Mortgage Bonds known as 1991 Series CP, limited to
                  an aggregate principal amount of $32,800,000, except as
                  otherwise provided in the Indenture hereinafter mentioned.
                  This bond and all other bonds of said series are issued and
                  to be issued under, and are all equally and ratably secured
                  (except insofar as any sinking, amortization, improvement or
                  analogous fund, established in accordance with the
                  provisions of the Indenture hereinafter mentioned, may
                  afford additional security for the bonds of any particular
                  series and except as provided in Section 3 of Article VI of
                  said Indenture) by an Indenture, dated as of October 1,
                  1924, duly executed by the Company to Bankers Trust Company,
                  a corporation of the State of New York, as Trustee, to which
                  Indenture and all indentures supplemental thereto (including
                  the Supplemental Indenture dated as of May 1, 1991)
                  reference is hereby made for a description of the properties
                  and franchises mortgaged and conveyed, the nature and extent
                  of the security, the terms and conditions upon which the
                  bonds are issued and under which additional bonds may be
                  issued, and the rights of the holders of the bonds and of
                  the Trustee in respect of such security (which Indenture and
                  all indentures supplemental thereto, including the
                  Supplemental Indenture dated as of May 1, 1991, are
                  hereinafter collectively called the "Indenture"). As
                  provided in the Indenture, said bonds may be for various
                  principal sums and are issuable in series, which may mature
                  at different times, may bear interest at different rates and
                  may otherwise vary as in said Indenture provided. With the
                  consent of the Company and to the extent permitted by and as
                  provided in the Indenture, the rights and obligations of the
                  Company and of the holders of the bonds and the terms and
                  provisions of the Indenture, or of any indenture
                  supplemental thereto, may be modified or altered in certain
                  respects by affirmative vote of at least eighty-five percent
                  (85%) in amount of the bonds then outstanding, and, if the
                  rights of one or more, but less than all, series of bonds
                  then outstanding are to be affected by the action proposed
                  to be taken, then also by affirmative vote of at least
                  eighty-five percent (85%) in amount of the series of bonds
                  so to be affected (excluding in every instance bonds
                  disqualified from voting by reason of the Company's interest
                  therein as specified in the Indenture); provided, however,
                  that, without the consent of the holder hereof, no such
                  modification or alteration shall, among other things, affect
                  the terms of payment of the principal of or the interest on
                  this bond, which in those respects is unconditional.

                    The holders of the bonds of 1991 Series CP, by their
                  acceptance of and holding thereof, consent and agree that
                  bonds of any series may be issued which mature on a date or
                  dates later than October 1, 2024 and also consent to the
                  deletion from the first paragraph of Section 5 of Article II
                  of the Indenture of the phrase "but in no event later than
                  October 1, 2024,". Such holders further agree that (a) such
                  consent shall, for all purposes of Article XV of the
                  Indenture and without further action on the part of such
                  holders, be deemed the affirmative vote of such holders at
                  any meeting called pursuant to said Article XV for the
                  purpose of approving such deletion, and (b) such deletion
                  shall become effective at such time as not less than
                  eighty-five per cent (85%) in principal amount of bonds
                  outstanding under the Indenture shall have consented thereto
                  substantially in the manner set forth in Section 4 of Part
                  II of the Supplemental Indenture dated as of May 1, 1991, or
                  in writing, or by affirmative vote cast at a meeting called
                  pursuant to said Article XV, or by any combination thereof.

                    This bond is redeemable upon the terms and conditions set
                  forth in the Indenture, including provision for redemption
                  upon demand of the Strategic Fund Trust Indenture Trustee
                  following the occurrence of an Event of Default under the
                  Strategic Fund Trust Indenture and the acceleration of the
                  principal of the Strategic Fund Revenue Bonds.

                      Under the Indenture, funds may be deposited with the
                    Trustee (which shall have become available for payment), in
                    advance of the redemption date of any of the bonds of 1991
                    Series CP (or portions thereof), in trust for the redemption
                    of such bonds (or portions thereof) and the interest due or
                    to become due thereon, and thereupon all obligations of the
                    Company in respect of such bonds (or portions thereof) so to
                    be redeemed and such interest shall cease and be discharged,
                    and the holders thereof shall thereafter be restricted
                    exclusively to such funds for any and all claims of
                    whatsoever nature on their part under the Indenture or with
                    respect to such bonds (or portions thereof) and interest.
 
                      In case an event of default, as defined in the Indenture,
                    shall occur, the principal of all the bonds issued
                    thereunder may become or be declared due and payable, in the
                    manner, with the effect and subject to the conditions
                    provided in the Indenture.

                      Upon payment of the principal of, or premium, if any, or
                    interest on, the Strategic Fund Revenue Bonds, whether at
                    maturity or prior to maturity by redemption or otherwise or
                    upon provision for the payment thereof having been made in
                    accordance with Article IV of the Strategic Fund Trust
                    Indenture, bonds of 1991 Series CP in a principal amount
                    equal to the principal amount of such Strategic Fund Revenue
                    Bonds and having both a corresponding maturity date and
                    interest rate shall, to the extent of such payment of
                    principal, premium or interest, be deemed fully paid and the
                    obligation of the Company thereunder to make such payment
                    shall forthwith cease and be discharged, and, in the case of
                    the payment of principal and premium, if any, such bonds of
                    said series shall be surrendered for cancellation or
                    presented for appropriate notation to the Trustee.

                      This bond is not assignable or transferable except as may
                    be required to effect a transfer to any successor trustee
                    under the Strategic Fund Trust Indenture, or, subject to
                    compliance with applicable law, as may be involved in the
                    course of the exercise of rights and remedies consequent
                    upon an Event of Default under the Strategic Fund Trust
                    Indenture. Any such transfer shall be made by the registered
                    holder hereof, in person or by his attorney duly authorized
                    in writing, on the books of the Company kept at its office
                    or agency in the Borough of Manhattan, The City and State of
                    New York, upon surrender and cancellation of this bond, and
                    thereupon, a new registered bond of the same series of
                    authorized denominations for a like aggregate principal
                    amount will be issued to the transferee in exchange
                    therefor, and this bond with others in like form may in like
                    manner be exchanged for one or more new bonds of the same
                    series of other authorized denominations, but of the same
                    aggregate principal amount, all as provided and upon the
                    terms and conditions set forth in the Indenture, and upon
                    payment, in any event, of the charges prescribed in the
                    Indenture.

                      No recourse shall be had for the payment of the principal
                    of or the interest on this bond, or for any claim based
                    hereon or otherwise in respect hereof or of the Indenture,
                    or of any indenture supplemental thereto, against any
                    incorporator, or against any past, present or future
                    stockholder, director or officer, as such, of the Company,
                    or of any predecessor or successor corporation, either
                    directly or through the Company or any such predecessor or
                    successor corporation, whether for amounts unpaid on stock
                    subscriptions or by virtue of any constitution, statute or
                    rule of law, or by the enforcement of any assessment or
                    penalty or otherwise howsoever; all such liability being, by
                    the acceptance hereof and as part of the consideration for
                    the issue hereof, expressly waived and released by every

               This bond and all other bonds of said series are issued and
               to be issued under, and are all equally and ratably secured
               (except insofar as any sinking, amortization, improvement or
               analogous fund, established in accordance with the
               provisions of the Indenture hereinafter mentioned, may
               afford additional security for the bonds of any particular
               series and except as provided in Section 3 of Article VI of
               said Indenture) by an Indenture, dated as of October 1,
               1924, duly executed by the Company to Bankers Trust Company,
               a corporation of the State of New York, as Trustee, to which
               Indenture and all indentures supplemental thereto (including
               the Supplemental Indenture dated as of May 15, 1991)
               reference is hereby made for a description of the properties
               and franchises mortgaged and conveyed, the nature and extent
               of the security, the terms and conditions upon which the
               bonds are issued and under which additional bonds may be
               issued, and the rights of the holders of the bonds and of
               the Trustee in respect of such security (which Indenture and
               all indentures supplemental thereto, including the
               Supplemental Indenture dated as of May 15, 1991, are
               hereinafter collectively called the "Indenture"). As
               provided in the Indenture, said bonds may be for various
               principal sums and are issuable in series, which may mature
               at different times, may bear interest at different rates and
               may otherwise vary as in said Indenture provided. With the
               consent of the Company and to the extent permitted by and as
               provided in the Indenture, the rights and obligations of the
               Company and of the holders of the bonds and the terms and
               provisions of the Indenture, or of any indenture
               supplemental thereto, may be modified or altered in certain
               respects by affirmative vote of at least eighty-five percent
               (85%) in amount of the bonds then outstanding, and, if the
               rights of one or more, but less than all, series of bonds
               then outstanding are to be affected by the action proposed
               to be taken, then also by affirmative vote of at least
               eighty-five percent (85%) in amount of the series of bonds
               so to be affected (excluding in every instance bonds
               disqualified from voting by reason of the Company's interest
               therein as specified in the Indenture); provided, however,
               that, without the consent of the holder hereof, no such
               modification or alteration shall, among other things, affect
               the terms of payment of the principal of or the interest on
               this bond, which in those respects is unconditional.

                 The holders of the bonds of 1991 Series DP, by their
               acceptance of and holding thereof, consent and agree that
               bonds of any series may be issued which mature on a date or
               dates later than October 1, 2024 and also consent to the
               deletion from the first paragraph of Section 5 of Article II
               of the Indenture of the phrase "but in no event later than
               October 1, 2024,". Such holders further agree that (a) such
               consent shall, for all purposes of Article XV of the
               Indenture and without further action on the part of such
               holders, be deemed the affirmative vote of such holders at
               any meeting called pursuant to said Article XV for the
               purpose of approving such deletion, and (b) such deletion
               shall become effective at such time as not less than
               eighty-five per cent (85%) in principal amount of bonds
               outstanding under the Indenture shall have consented thereto
               substantially in the manner set forth in Section 4 of Part I
               of the Supplemental Indenture dated as of May 15, 1991, or
               in writing, or by affirmative vote cast at a meeting called
               pursuant to said Article XV, or by any combination thereof.

                 This bond is redeemable upon the terms and conditions set
               forth in the Indenture, including provision for redemption
               upon demand of the Superior Trust Indenture Trustee
               following the occurrence of an Event of Default under the
               Superior Trust Indenture and the acceleration of the
               principal of the Superior Revenue Bonds.

                 Under the Indenture, funds may be deposited with the
               Trustee (which shall have become available for payment), in
               advance of the redemption date of any of the bonds of 1991
               Series DP (or portions thereof), in trust for the redemption
               of such bonds (or portions thereof) and the interest due or
               to become due thereon, and thereupon all obligations of the
               Company in respect of such bonds (or portions thereof) so to
               be redeemed and such interest shall cease and be discharged,
               and the holders thereof shall thereafter be restricted
               exclusively to such funds for any and all claims of
               whatsoever nature on their part under the Indenture or with
               respect to such bonds (or portions thereof) and interest.

                 In case an event of default, as defined in the Indenture,
               shall occur, the principal of all the bonds issued
               thereunder may become or be declared due and payable, in the
               manner, with the effect and subject to the conditions
               provided in the Indenture.

                 Upon payment of the principal of, or premium, if any, or
               interest on, the Superior Revenue Bonds, whether at maturity
               or prior to maturity by redemption or otherwise or upon
               provision for the payment thereof having been made in
               accordance with Article IV of the Superior Trust Indenture,
               bonds of 1991 Series DP in a principal amount equal to the
               principal amount of such Superior Revenue Bonds and having
               both a corresponding maturity date and interest rate shall,
               to the extent of such payment of principal, premium or
               interest, be deemed fully paid and the obligation of the
               Company thereunder to make such payment shall forthwith
               cease and be discharged, and, in the case of the payment of
               principal and premium, if any, such bonds of said series
               shall be surrendered for cancellation or presented for
               appropriate notation to the Trustee.

                 This bond is not assignable or transferable except as may
               be required to effect a transfer to any successor trustee
               under the Superior Trust Indenture, or, subject to
               compliance with applicable law, as may be involved in the
               course of the exercise of rights and remedies consequent
               upon an Event of Default under the Superior Trust Indenture.
               Any such transfer shall be made by the registered holder
               hereof, in person or by his attorney duly authorized in
               writing, on the books of the Company kept at its office or
               agency in the Borough of Manhattan, The City and State of
               New York, upon surrender and cancellation of this bond, and
               thereupon, a new registered bond of the same series of
               authorized denominations for a like aggregate principal
               amount will be issued to the transferee in exchange
               therefor, and this bond with others in like form may in like
               manner be exchanged for one or more new bonds of the same
               series of other authorized denominations, but of the same
               aggregate principal amount, all as provided and upon the
               terms and conditions set forth in the Indenture, and upon
               payment, in any event, of the charges prescribed in the
               Indenture.

                 No recourse shall be had for the payment of the principal
               of or the interest on this bond, or for any claim based
               hereon or otherwise in respect hereof or of the Indenture,
               or of any indenture supplemental thereto, against any
               incorporator, or against any past, present or future
               stockholder, director or officer, as such, of the Company,
               or of any predecessor or successor corporation, either
               directly or through the Company or any such predecessor or
               successor corporation, whether for amounts unpaid on stock
               subscriptions or by virtue of any constitution, statute or
               rule of law, or by the enforcement of any assessment or
               penalty or otherwise howsoever; all such liability being, by
               the acceptance hereof and as part of the consideration for
               the issue hereof, expressly waived and released by every
               holder or owner hereof, as more fully provided in the
               Indenture.

                  obligation of the Company thereunder to make such payment
                  shall forthwith cease and be discharged, and, in the case of

                 Company, unlimited as to amount except as provided in the
                 Indenture hereinafter mentioned or any indentures

                 to be issued under, and are all equally and ratably secured
                 (except insofar as any sinking, amortization, improvement or
                 analogous fund, established in accordance with the
                 provisions of the Indenture hereinafter mentioned, may
                 afford additional security for the bonds of any particular
                 series and except as provided in Section 3 of Article VI of
                 said Indenture) by an Indenture, dated as of October 1,
                 1924, duly executed by the Company to Bankers Trust Company,
                 a corporation of the State of New York, as Trustee, to which
                 Indenture and all indentures supplemental thereto (including
                 the Supplemental Indenture dated as of September 1, 1991)
                 reference is hereby made for a description of the properties
                 and franchises mortgaged and conveyed, the nature and extent
                 of the security, the terms and conditions upon which the
                 bonds are issued and under which additional bonds may be
                 issued, and the rights of the holders of the bonds and of
                 the Trustee in respect of such security (which Indenture and

                 Supplemental Indenture dated as of September 1, 1991, are
                 hereinafter collectively called the "Indenture"). As
                 provided in the Indenture, said bonds may be for various

                 at different times, may bear interest at different rates and
                 may otherwise vary as in said Indenture provided. With the
                 consent of the Company and to the extent permitted by and as
                 provided in the Indenture, the rights and obligations of the
                 Company and of the holders of the bonds and the terms and
                 provisions of the Indenture, or of any indenture
                 supplemental thereto, may be modified or altered in certain
                 respects by affirmative vote of at least eighty-five percent
                 (85%) in amount of the bonds then outstanding, and, if the
                 rights of one or more, but less than all, series of bonds
                 then outstanding are to be affected by the action proposed
                 to be taken, then also by affirmative vote of at least
                 eighty-five percent (85%) in amount of the series of bonds
                 so to be affected (excluding in every instance bonds
                 disqualified from voting by reason of the Company's interest
                 therein as specified in the Indenture); provided, however,
                 that, without the consent of the holder hereof, no such
                 modification or alteration shall, among other things, affect
                 the terms of payment of the principal of or the interest on
                 this bond, which in those respects is unconditional.

                   The holders of the bonds of 1991 Series EP, by their
                 acceptance of and holding thereof, consent and agree that
                 bonds of any series may be issued which mature on a date or

                 deletion from the first paragraph of Section 5 of Article II
                 of the Indenture of the phrase "but in no event later than
                 October 1, 2024,". Such holders further agree that (a) such
                 consent shall, for all purposes of Article XV of the
                 Indenture and without further action on the part of such
                 holders, be deemed the affirmative vote of such holders at
                 any meeting called pursuant to said Article XV for the
                 purpose of approving such deletion, and (b) such deletion
                 shall become effective at such time as not less than
                 eighty-five per cent (85%) in principal amount of bonds
                 outstanding under the Indenture shall have consented thereto
                 substantially in the manner set forth in Section 4 of Part I
                 of the Supplemental Indenture dated as of September 1, 1991,

                  or agency in the Borough of Manhattan, The City and State of
                  New York, upon surrender and cancellation of this bond, and
                  thereupon, a new registered bond of the same series of
                  authorized denominations for a like aggregate principal
                  amount will be issued to the transferee in exchange
                  therefor, and this bond with others in like form may in like

                  series of other authorized denominations, but of the same
                  aggregate principal amount, all as provided and upon the
                  terms and conditions set forth in the Indenture, and upon
                  payment, in any event, of the charges prescribed in the
                  Indenture.

                    No recourse shall be had for the payment of the principal
                  of or the interest on this bond, or for any claim based
                  hereon or otherwise in respect hereof or of the Indenture,
                  or of any indenture supplemental thereto, against any
                  incorporator, or against any past, present or future
                  stockholder, director or officer, as such, of the Company,
                  or of any predecessor or successor corporation, either
                  directly or through the Company or any such predecessor or
                  successor corporation, whether for amounts unpaid on stock
                  subscriptions or by virtue of any constitution, statute or
                  rule of law, or by the enforcement of any assessment or
                  penalty or otherwise howsoever; all such liability being, by
                  the acceptance hereof and as part of the consideration for
                  the issue hereof, expressly waived and released by every
                  holder or owner hereof, as more fully provided in the

                   THE DETROIT EDISON COMPANY (hereinafter called the
                 "Company"), a corporation of the State of Michigan, for
                 value received, hereby promises to pay to the Michigan
                 Strategic Fund, or registered assigns, at the Company's
                 office or agency in the Borough of Manhattan, The City and
                 State of New York, the principal sum of            dollars
                 ($)            in lawful money of the United States of
                 America on the date specified in the title hereof and
                 interest thereon at the rate specified in the title hereof,
                 in like lawful money, from December 1, 1991, and after the
                 first payment of interest on bonds of this Series has been
                 made or otherwise provided for, from the most recent date to
                 which interest has been paid or otherwise provided for,
                 semi-annually on June 1 and December 1 of each year
                 (commencing June 1, 1992), until the Company's obligation
                 with respect to payment of said principal shall have been
                 discharged, all as provided, to the extent and in the manner
                 specified in the Indenture hereinafter mentioned on the
                 reverse hereof and in the supplemental indenture pursuant to
                 which this bond has been issued.

                   Under a Trust Indenture, dated as of December 1, 1991
                 (hereinafter called the "Strategic Fund Trust Indenture"),
                 between the Michigan Strategic Fund (hereinafter called
                 "Strategic Fund"), and Manufacturers Bank, N.A., as trustee
                 (hereinafter called the "Strategic Fund Trust Indenture
                 Trustee"), the Strategic Fund has issued Limited Obligation
                 Refunding Revenue Bonds (The Detroit Edison Company

                 Fund and simultaneously irrevocably assigned to the
                 Strategic Fund Trust Indenture Trustee so as to secure the

                 bond as further provided herein and in the supplemental
                 indenture pursuant to which this bond has been issued.

                   Reference is hereby made to such further provisions of
                 this bond set forth on the reverse hereof and such further
                 provisions shall for all purposes have the same effect as
                 though set forth at this place.

                   This bond shall not be valid or become obligatory for any
                 purpose until Bankers Trust Company, the Trustee under the
                 Indenture hereinafter mentioned on the reverse hereof, or
                 its successor thereunder, shall have signed the form of
                 certificate endorsed hereon.

                           [FORM OF REVERSE OF BOND]
 
                   This bond is one of an authorized issue of bonds of the
                 Company, unlimited as to amount except as provided in the
                 Indenture hereinafter mentioned or any indentures
                 supplemental thereto, and is one of a series of General and
                 Refunding Mortgage Bonds known as 1991 Series FP, limited to
                 an aggregate principal amount of $98,375,000, except as
                 otherwise provided in the Indenture hereinafter mentioned.
                 This bond and all other bonds of said series are issued and
                 to be issued under, and are all equally and ratably secured
                 (except insofar as any sinking, amortization, improvement or
                 analogous fund, established in accordance with the
                 provisions of the Indenture hereinafter mentioned, may
                 afford additional security for the bonds of any particular
                 series and except as provided in Section 3 of Article VI of
                 said Indenture) by an Indenture, dated as of October 1,
                 1924, duly executed by the Company to Bankers Trust Company,
                 a corporation of the State of New York, as Trustee, to which
                 Indenture and all indentures supplemental thereto (including
                 the Supplemental Indenture dated as of November 1, 1991)
                 reference is hereby made for a description of the properties
                 and franchises mortgaged and conveyed, the nature and extent
                 of the security, the terms and conditions upon which the
                 bonds are issued and under which additional bonds may be
                 issued, and the rights of the holders of the bonds and of
                 the Trustee in respect of such security (which Indenture and
                 all indentures supplemental thereto, including the
                 Supplemental Indenture dated as of November 1, 1991, are
                 hereinafter collectively called the "Indenture"). As
                 provided in the Indenture, said bonds may be for various
                 principal sums and are issuable in series, which may mature
                 at different times, may bear interest at different rates and
                 may otherwise vary as in said Indenture provided. With the
                 consent of the Company and to the extent permitted by and as
                 provided in the Indenture, the rights and obligations of the
                 Company and of the holders of the bonds and the terms and
                 provisions of the Indenture, or of any indenture
                 supplemental thereto, may be modified or altered in certain
                 respects by affirmative vote of at least eighty-five percent
                 (85%) in amount of the bonds then outstanding, and, if the
                 rights of one or more, but less than all, series of bonds
                 then outstanding are to be affected by the action proposed
                 to be taken, then also by affirmative vote of at least
                 eighty-five percent (85%) in amount of the series of bonds
                 so to be affected (excluding in every instance bonds
                 disqualified from voting by reason of the Company's interest
                 therein as specified in the Indenture); provided, however,
                 that, without the consent of the holder hereof, no such
                 modification or alteration shall, among other things, affect
                 the terms of payment of the principal of or the interest on
                 this bond, which in those respects is unconditional.

                   The holders of the bonds of 1991 Series FP, by their
                 acceptance of and holding thereof, consent and agree that
                 bonds of any series may be issued which mature on a date or
                 dates later than October 1, 2024 and also consent to the
                 deletion from the first paragraph of Section 5 of Article II
                 of the Indenture of the phrase "but in no event later than
                 October 1, 2024,". Such holders further agree that (a) such
                 consent shall, for all purposes of Article XV of the
                 Indenture and without further action on the part of such
                 holders, be deemed the affirmative vote of such holders at
                 any meeting called pursuant to said Article XV for the
                 purpose of approving such deletion, and (b) such deletion
                 shall become effective at such time as not less than
                 eighty-five per cent (85%) in principal amount of bonds
                 outstanding under the Indenture shall have consented thereto
                 substantially in the manner set forth in Section 4 of Part I
                 of the Supplemental Indenture dated as of November 1, 1991,
                 or in writing, or by affirmative vote cast at a meeting
                 called pursuant to said Article XV, or by any combination
                 thereof.

                   This bond is redeemable upon the terms and conditions set
                 forth in the Indenture, including provision for redemption
                 upon demand of the Strategic Fund Trust Indenture Trustee
                 following the occurrence of an Event of Default under the
                 Strategic Fund Trust Indenture and the acceleration of the
                 principal of the Strategic Fund Revenue Bonds.

                   Under the Indenture, funds may be deposited with the
                 Trustee (which shall have become available for payment), in
                 advance of the redemption date of any of the bonds of 1991
                 Series FP (or portions thereof), in trust for the redemption
                 of such bonds (or portions thereof) and the interest due or
                 to become due thereon, and thereupon all obligations of the
                 Company in respect of such bonds (or portions thereof) so to
                 be redeemed and such interest shall cease and be discharged,
                 and the holders thereof shall thereafter be restricted
                 exclusively to such funds for any and all claims of
                 whatsoever nature on their part under the Indenture or with
                 respect to such bonds (or portions thereof) and interest.

                   In case an event of default, as defined in the Indenture,
                 shall occur, the principal of all the bonds issued
                 thereunder may become or be declared due and payable, in the
                 manner, with the effect and subject to the conditions
                 provided in the Indenture.

                   Upon payment of the principal of, or premium, if any, or
                 interest on, the Strategic Fund Revenue Bonds, whether at
                 maturity or prior to maturity by redemption or otherwise or
                 upon provision for the payment thereof having been made in
                 accordance with Articles I or IV of the Strategic Fund Trust
                 Indenture, bonds of 1991 Series FP in a principal amount
                 equal to the principal amount of such Strategic Fund Revenue
                 Bonds and having both a corresponding maturity date and
                 interest rate shall, to the extent of such payment of
                 principal, premium or interest, be deemed fully paid and the
                 obligation of the Company thereunder to make such payment
                 shall forthwith cease and be discharged, and, in the case of
                 the payment of principal and premium, if any, such bonds of
                 said series shall be surrendered for cancellation or
                 presented for appropriate notation to the Trustee.

                   This bond is not assignable or transferable except as may
                 be required to effect a transfer to any successor trustee
                 under the Strategic Fund Trust Indenture, or, subject to
                 compliance with applicable law, as may be involved in the
                 course of the exercise of rights and remedies consequent
                 upon an Event of Default under the Strategic Fund Trust
                 Indenture. Any such transfer shall be made by the registered
                 holder hereof, in person or by his attorney duly authorized
                 in writing, on the books of the Company kept at its office
                 or agency in the Borough of Manhattan, The City and State of
                 New York, upon surrender and cancellation of this bond, and
                 thereupon, a new registered bond of the same series of
                 authorized denominations for a like aggregate principal
                 amount will be issued to the transferee in exchange
                 therefor, and this bond with others in like form may in like
                 manner be exchanged for one or more new bonds of the same
                 series of other authorized denominations, but of the same
                 aggregate principal amount, all as provided and upon the
                 terms and conditions set forth in the Indenture, and upon
                 payment, in any event, of the charges prescribed in the
                 Indenture.

                   No recourse shall be had for the payment of the principal
                 of or the interest on this bond, or for any claim based
                 hereon or otherwise in respect hereof or of the Indenture,
                 or of any indenture supplemental thereto, against any
                 incorporator, or against any past, present or future
                 stockholder, director or officer, as such, of the Company,
                 or of any predecessor or successor corporation, either
                 directly or through the Company or any such predecessor or
                 successor corporation, whether for amounts unpaid on stock
                 subscriptions or by virtue of any constitution, statute or
                 rule of law, or by the enforcement of any assessment or
                 penalty or otherwise howsoever; all such liability being, by
                 the acceptance hereof and as part of the consideration for
                 the issue hereof, expressly waived and released by every
                 holder or owner hereof, as more fully provided in the
                 Indenture.

                           [FORM OF REVERSE OF BOND]
 
                    This bond is one of an authorized issue of bonds of the
                  Company, unlimited as to amount except as provided in the
                  Indenture hereinafter mentioned or any indentures
                  supplemental thereto, and is one of a series of General and
                  Refunding Mortgage Bonds known as 1992 Series BP, limited to
                  an aggregate principal amount of $20,975,000, except as
                  otherwise provided in the Indenture hereinafter mentioned.
                  This bond and all other bonds of said series are issued and
                  to be issued under, and are all equally and ratably secured
                  (except insofar as any sinking, amortization, improvement or
                  analogous fund, established in accordance with the
                  provisions of the Indenture hereinafter mentioned, may
                  afford additional security for the bonds of any particular
                  series and except as provided in Section 3 of Article VI of
                  said Indenture) by an Indenture, dated as of October 1,
                  1924, duly executed by the Company to Bankers Trust Company,
                  a corporation of the State of New York, as Trustee, to which
                  Indenture and all indentures supplemental thereto (including
                  the Supplemental Indenture dated as of January 15, 1992)
                  reference is hereby made for a description of the properties
                  and franchises mortgaged and conveyed, the nature and extent
                  of the security, the terms and conditions upon which the
                  bonds are issued and under which additional bonds may be
                  issued, and the rights of the holders of the bonds and of
                  the Trustee in respect of such security (which Indenture and
                  all indentures supplemental thereto, including the
                  Supplemental Indenture dated as of January 15, 1992, are
                  hereinafter collectively called the "Indenture"). As
                  provided in the Indenture, said bonds may be for various
                  principal sums and are issuable in series, which may mature
                  at different times, may bear interest at different rates and
                  may otherwise vary as in said Indenture provided. With the
                  consent of the Company and to the extent permitted by and as
                  provided in the Indenture, the rights and obligations of the
                  Company and of the holders of the bonds and the terms and
                  provisions of the Indenture, or of any indenture
                  supplemental thereto, may be modified or altered in certain
                  respects by affirmative vote of at least eighty-five percent
                  (85%) in amount of the bonds then outstanding, and, if the
                  rights of one or more, but less than all, series of bonds
                  then outstanding are to be affected by the action proposed
                  to be taken, then also by affirmative vote of at least
                  eighty-five percent (85%) in amount of the series of bonds
                  so to be affected (excluding in every instance bonds
                  disqualified from voting by reason of the Company's interest
                  therein as specified in the Indenture); provided, however,
                  that, without the consent of the holder hereof, no such
                  modification or alteration shall, among other things, affect
                  the terms of payment of the principal of or the interest on
                  this bond, which in those respects is unconditional.

                    The holders of the bonds of 1992 Series BP, by their
                  acceptance of and holding thereof, consent and agree that
                  bonds of any series may be issued which mature on a date or
                  dates later than October 1, 2024 and also consent to the
                  deletion from the first paragraph of Section 5 of Article II
                  of the Indenture of the phrase "but in no event later than
                  October 1, 2024,". Such holders further agree that (a) such
                  consent shall, for all purposes of Article XV of the
                  Indenture and without further action on the part of such
                  holders, be deemed the affirmative vote of such holders at
                  any meeting called pursuant to said Article XV for the
                  purpose of approving such deletion, and (b) such deletion
                  shall become effective at such time as not less than
                  eighty-five per cent (85%) in principal amount of bonds
                  outstanding under the Indenture shall have consented thereto
                  substantially in the manner set forth in Section 4 of Part I
                  of the Supplemental Indenture dated as of January 15, 1992,
                  or in writing, or by affirmative vote cast at a meeting
                  called pursuant to said Article XV, or by any combination
                  thereof.

                    This bond is redeemable upon the terms and conditions set
                  forth in the Indenture, including provision for redemption
                  upon demand of the Strategic Fund Trust Indenture Trustee
                  following the occurrence of an Event of Default under the
                  Strategic Fund Trust Indenture and the acceleration of the
                  principal of the Strategic Fund Revenue Bonds.

                    Under the Indenture, funds may be deposited with the
                  Trustee (which shall have become available for payment), in
                  advance of the redemption date of any of the bonds of 1992
                  Series BP (or portions thereof), in trust for the redemption
                  of such bonds (or portions thereof) and the interest due or
                  to become due thereon, and thereupon all obligations of the
                  Company in respect of such bonds (or portions thereof) so to
                  be redeemed and such interest shall cease and be discharged,
                  and the holders thereof shall thereafter be restricted
                  exclusively to such funds for any and all claims of
                  whatsoever nature on their part under the Indenture or with
                  respect to such bonds (or portions thereof) and interest.

                    In case an event of default, as defined in the Indenture,
                  shall occur, the principal of all the bonds issued
                  thereunder may become or be declared due and payable, in the
                  manner, with the effect and subject to the conditions
                  provided in the Indenture.

                    Upon payment of the principal of, or premium, if any, or
                  interest on, the Strategic Fund Revenue Bonds, whether at
                  maturity or prior to maturity by redemption or otherwise or
                  upon provision for the payment thereof having been made in
                  accordance with Articles I or IV of the Strategic Fund Trust
                  Indenture, bonds of 1992 Series BP in a principal amount
                  equal to the principal amount of such Strategic Fund Revenue
                  Bonds and having both a corresponding maturity date and
                  interest rate shall, to the extent of such payment of
                  principal, premium or interest, be deemed fully paid and the
                  obligation of the Company thereunder to make such payment
                  shall forthwith cease and be discharged, and, in the case of
                  the payment of principal and premium, if any, such bonds of
                  said series shall be surrendered for cancellation or
                  presented for appropriate notation to the Trustee.

                    This bond is not assignable or transferable except as may
                  be required to effect a transfer to any successor trustee
                  under the Strategic Fund Trust Indenture, or, subject to
                  compliance with applicable law, as may be involved in the
                  course of the exercise of rights and remedies consequent
                  upon an Event of Default under the Strategic Fund Trust
                  Indenture. Any such transfer shall be made by the registered
                  holder hereof, in person or by his attorney duly authorized
                  in writing, on the books of the Company kept at its office
                  or agency in the Borough of Manhattan, The City and State of
                  New York, upon surrender and cancellation of this bond, and
                  thereupon, a new registered bond of the same series of
                  authorized denominations for a like aggregate principal
                  amount will be issued to the transferee in exchange
                  therefor, and this bond with others in like form may in like
                  manner be exchanged for one or more new bonds of the same
                  series of other authorized denominations, but of the same
                  aggregate principal amount, all as provided and upon the
                  terms and conditions set forth in the Indenture, and upon
                  payment, in any event, of the charges prescribed in the
                  Indenture.

                    No recourse shall be had for the payment of the principal
                  of or the interest on this bond, or for any claim based
                  hereon or otherwise in respect hereof or of the Indenture,
                  or of any indenture supplemental thereto, against any
                  incorporator, or against any past, present or future
                  stockholder, director or officer, as such, of the Company,
                  or of any predecessor or successor corporation, either
                  directly or through the Company or any such predecessor or
                  successor corporation, whether for amounts unpaid on stock
                  subscriptions or by virtue of any constitution, statute or
                  rule of law, or by the enforcement of any assessment or
                  penalty or otherwise howsoever; all such liability being, by
                  the acceptance hereof and as part of the consideration for
                  the issue hereof, expressly waived and released by every
                  holder or owner hereof, as more fully provided in the
                  Indenture.

                           THE DETROIT EDISON COMPANY
                     SUPPLEMENTAL LONG TERM DISABILITY PLAN


The Detroit Edison Company Supplemental Long Term Disability Plan ("SLTD"),
established by the Detroit Edison Company (the "Company") effective November 5,
1991 is hereby amended and restated as of January 27, 1997.


SECTION 1 - PURPOSE

The SLTD Plan supplements on a limited basis the benefits payable under the
qualified Long Term Disability ("LTD") Plan. The SLTD Plan ensures that all
employees of Detroit Edison or a participating affiliate who become eligible to
and do receive benefits under the LTD Plan of The Detroit Edison Company will,
to the extent their base pay is not covered by the qualified plan, receive the
same dollar amount of benefits as they would have received were it not for the
limitations imposed on the maximum base pay recognized under the LTD Plan. All
of the terms set forth under the LTD Plan are applicable to the SLTD Plan.

SECTION 2 - ADMINISTRATION

The SLTD Plan shall be administered by the Director - Benefit Plan
Administration as an unfunded, unsecured plan. The Administrator's decisions
in all matters involving the interpretation and application of the SLTD Plan
shall be conclusive.

SECTION 3 - ELIGIBILITY

Employees of Detroit Edison or a participating affiliate whose benefits under
the LTD Plan are limited due to the maximum base pay recognized under that plan
shall be eligible for the benefits provided by the SLTD Plan. In no event shall
a person who is not entitled to benefits under the LTD Plan be eligible for any
benefits under the SLTD Plan.

Participating in the SLTD Plan does not guarantee continued employment with the
Company or the participating affiliate.

SECTION 4 - AMOUNT OF BENEFITS

A claim filed under the LTD Plan shall be deemed filed under the SLTD Plan when
applicable. For that portion of base pay in excess of the amount eligible for
benefits 


                                       1
<PAGE>   2
under the qualified LTD Plan, the amount of the benefit payable under the SLTD
Plan shall be determined using the formula provided under the LTD Plan.

SECTION 5 - PAYMENT OF BENEFITS

Payment of benefits under the SLTD Plan shall be made coincident with the
payment of benefits under the LTD Plan or as soon as practicable thereafter.

Benefits under the SLTD Plan shall be payable solely from the general assets of
the Company or the participating affiliate.

SECTION 6 - AMENDMENT AND DISCONTINUANCE

The Company or participating affiliate reserves the right to amend, modify,
supplement or terminate the SLTD Plan at any time.

Mr. David E. Meador

Troy, MI 48084

Dear Dave:

I am pleased to offer you employment in the position of Vice President and
Controller of Detroit Edison at an annual salary of $220,000.

Upon employment, you will be eligible for the benefits described in the
Benefit Highlights brochure enclosed as well as the perquisites described on a
separate listing also enclosed. In addition, pending approval by the
Organization and Compensation Committee of the Board of Directors, you will
receive the following:

- -  You will be granted 5,000 shares of restricted stock to compensate for the
   loss of unvested options of Chrysler stock. All shares will have a vesting
   period of three (3) years with immediate vesting if your employment is
   terminated other than for cause prior to the end of three years service.

- -  You will be granted 14,000 shares of nonqualified stock options pursuant to
   the Company's Long Term Incentive Plan.

- -  You will be paid an amount (considered imputed income) to cover the premium
   for three months health care coverage under the Company's plan.

- -  You will receive an immediate annual benefit of four weeks vacation.

- -  You will be awarded ten (10) years of "awarded service". After meeting the
   eligibility requirements for age and actual service of our Management
   Supplemental Benefit Plan (MSBP), "awarded service" will be included in the
   calculation of your benefit under the Plan. This benefit will be offset by
   any retirement income expected from any previous employers.

- -  If within three years of your employment you are terminated for any reason
   other than cause, you will receive an amount equivalent to one year's base
   salary. 


                                                                    1 of 2

As a member of Senior Management, you will be considered for additional grants
of stock (i.e., performance restricted stock and stock options) under our Long
Term Incentive Plan in February 1997.

The Company does not currently have a change in control policy. However, there
are certain change in control features in our restricted stock agreements and
the rabbi trusts covering the benefits provided under our Savings Reparation
Plan, Retirement Reparation Plan, and Management Supplemental Benefit Plan. The
Organization and Compensation Committee of the Board of Directors will address
change in control at a future meeting.

This offer is subject to successful completion of a pre-employment physical
examination, a review of references and completion of our employment history
form.

Please contact me at (313) 235-8610 after you have completed your review of our
offer of employment.

I am looking forward to you joining the Company and hope to hear from you soon.


Sincerely,


[sig]
