                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS
 
Second quarter earnings increase to record high -- MCN's earnings from
continuing operations for the 1997 quarter increased 75% or $3.9 million over
the second quarter of 1996. Earnings from continuing operations for the 1997
six- and twelve-month periods increased $6.6 million and $3.9 million,
respectively, over the comparable 1996 periods. As discussed below, this
performance primarily reflects the success of the strategies implemented by the
Diversified Energy group.
 
MCN's earnings comparisons were also affected by income from discontinued
operations. As discussed in the "Discontinued Operations" section that follows,
MCN sold The Genix Group, Inc. (Genix) during the second quarter of 1996.

Strategic direction -- MCN's objective is to achieve superior, long-term returns
for its shareholders. To accomplish this, MCN will aggressively invest in a
diverse portfolio of domestic and international energy-related projects. The
success of this strategy will be demonstrated by the growth of MCN's earnings
and the total return to its shareholders over time.
 
DIVERSIFIED ENERGY
 
Earnings continue to rise -- The Diversified Energy group reported an increase
in earnings of $3.5 million for the 1997 quarter from the comparable 1996
period. Earnings for the 1997 six- and twelve-month periods increased $13.6
million and $22.8 million, respectively. Increased earnings were driven
primarily by significantly higher levels of operating and joint venture income,
partially offset by increased financing costs

associated with additional capital needed to fund investments. Diversified
Energy continues to provide an increasing portion of MCN's earnings,
contributing 38% for the twelve months ended June 30, 1997, double the
contribution in the comparable 1996 period.

EXPLORATION & PRODUCTION operating and joint venture income increased $6.2
million for the 1997 quarter and $17.8 million and $26.4 million for the six-and
twelve-month periods, respectively. The results reflect a significant increase
in the level of gas and oil produced due to the development and acquisition of
interests in properties during 1995 and 1996. Gas and oil production increased

*Average oil sales prices have been adjusted for amounts received or paid under

E&P operating and joint venture results were also affected by fluctuations in
natural gas and oil sales prices, which were mitigated by the effect of hedging
with swap and futures agreements. These hedging agreements are used to manage
Diversified Energy's exposure to the risk of market price fluctuations.
Additionally, E&P's operating results were affected by higher average production
costs per Mcf equivalent.
 
PIPELINES & PROCESSING operating and joint venture income increased $4.2 million
for the 1997 quarter and increased $8.9 million and $14.6 million for the six-
and twelve-month periods, respectively. The increases primarily reflect income
from the December 1996 acquisition of a 25% interest in Lyondell Methanol
Company, L.P. (Lyondell), a limited partnership that owns and operates a 248
million gallon per year methanol production plant in Texas. Earnings from
Lyondell have benefited from higher than expected methanol prices during 1997.
Pipeline & Processing results also reflect a higher level of volumes treated
through gas processing plants, as well as increases in transportation deliveries
due to the acquisition of additional pipeline interests during late 1995 and
1996. These increases in transportation volumes were partially offset by reduced
volumes resulting from the sale of a portion of MCN's interest in Dauphin Island
Gathering Partners (DIGP) during 1996 (Note 2c).

ENERGY MARKETING, GAS STORAGE & POWER GENERATION operating and joint venture
income increased $6.5 million for the 1997 quarter and increased $6.0 million
and $12.7 million for the six- and twelve-month periods, respectively. The
increase in earnings during the quarter resulted from a 55% increase in gas
sales and exchange deliveries as well as slightly higher gas sales margins. The
increases in earnings for the 1997 six- and twelve-month periods were due to
increases in gas sales and exchange deliveries of 33% and 24%, respectively,
partially offset by lower gas sales margins. Also contributing to the 1997
results were earnings from the April 1997 acquisition of an 18.1% interest in
Midland Cogeneration Venture L.P., a limited partnership that owns a gas-fired
cogeneration facility capable of producing approximately 1,370 megawatts (MW) of
electricity and 1.35 million pounds per hour of process steam (Note 2b).

Additionally, Power Generation experienced higher earnings from its investment
in the 50%-owned, 123 MW Michigan Power cogeneration facility due to an increase
in electricity sales rates under its long-term sales contract. Results for 1997
also reflect increased earnings from the 30 MW Ada cogeneration facility as a
result of Power Generation's acquisition of the 1% general partnership interest
in the fourth quarter of 1996.
 
RISK MANAGEMENT STRATEGY -- MCN primarily manages commodity price risk by
utilizing futures, options and swap contracts to more closely balance its
portfolio of supply and sales agreements. MCN has hedged most of its gas and oil
production not covered by long-term, fixed-price sales obligations. MCN's Energy
Marketing group coordinates all of MCN's hedging activities to ensure compliance
with risk management policies established by MCN's Board of Directors. Certain
hedging gains or losses related to gas and oil production are recorded by MCN's
E&P operations. Gains and losses on gas-related hedging transactions that are
not recorded by MCN's E&P group are absorbed by Energy Marketing.
 
CORPORATE & OTHER operating and joint venture losses reflect administrative
expenses associated with corporate management activities. The Diversified Energy
group has been charged a larger portion of such expenses, reflecting its growing
percentage of MCN. The 1996 periods include a $1.7 million gain from the sale of
land by a 50%-owned real estate joint venture.
 
OTHER INCOME AND DEDUCTIONS
 
The 1997 quarter, six- and twelve-month periods reflect higher interest costs on
increased borrowings required to finance capital investments in the Diversified
Energy group. In addition, the 1997 periods reflect dividends on $80 million of
preferred securities issued in July 1996, $132 million of preferred securities
issued in March 1997 and $200 million of preferred securities issued in June
1997.
 
Other income and deductions for the 1997 twelve-month period, as well as the
1996 quarter, six- and twelve-month periods, includes gains related to DIGP
(Note 2c). In a series of transactions during 1996, MCN sold 64% of its 99%
interest in the DIGP partnership, resulting in pre-tax gains totaling $8.8
million, of which $2.4 million was deferred until the third quarter of 1997 when
the related option agreement expired unexercised. Other income and deductions
for the 1997 six- and twelve- month periods also includes gains on the sale of
pipeline assets.
 
INCOME TAXES
 
The current and deferred income tax provisions for all periods reflect increases
in pre-tax earnings. These taxes were reduced by an increase in the level of gas
production tax credits generated from E&P projects.
 
OUTLOOK
 
MCN plans to continue aggressively growing its E&P reserve base in known
producing areas, generating attractive returns and developing reliable,
long-term gas supplies. MCN will also continue to make investments in natural
gas and gas liquid gathering and processing facilities near these known
producing areas, concentrating on those with the highest growth potential.
Additionally, MCN will focus on expanding its

Energy Marketing coverage within existing markets as well as entering new
markets through strategic alliances with other energy providers. MCN's Power
Generation business is expected to make significant investments in international
projects over the next several years as evidenced by its acquisition of a 40%
interest in a joint venture in India (Note 2a). MCN is currently evaluating
various other projects that could add significantly to its international
portfolio.
 
GAS DISTRIBUTION
 
Results reflect solid financial performance -- The Gas Distribution group
reported an increase in earnings of $.4 million for the 1997 quarter, reflecting
improved gross margins resulting from higher gas sales and transportation
deliveries due in part to colder weather. Results for the 1997 quarter also
reflect lower operation and maintenance expenses, partially offset by higher
depreciation and financing costs. Earnings decreased $7.0 million and $18.9
million for the 1997 six- and twelve-month periods, respectively, reflecting
reduced gross margins due to warmer weather as well as higher operating expenses
and financing costs.

          OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)
 
GROSS MARGIN
 
Gross margin reflects varying weather -- Gas Distribution gross margin
(operating revenues less cost of gas) increased $4.2 million for the 1997
quarter and decreased $4.6 million and $16.4 million for the six- and
twelve-month periods, respectively. These varying results are primarily due to
fluctuations in gas sales and end user transportation deliveries that were
driven by the colder weather during the 1997 quarter and the warmer weather
during the 1997 six- and twelve-month periods. All periods were affected by
increased revenues as a result of the continued growth in intermediate
transportation services.

GAS SALES AND END USER TRANSPORTATION revenues in total decreased $16.6 million
and $23.3 million in the 1997 quarter and six-month period and increased $4.8
million in the 1997 twelve-month period. The decrease in revenues for the
quarter reflects a reduction in gas sales rates driven by lower gas costs as
subsequently discussed. This decrease in revenues attributable to reduced gas
sales rates was partially offset by increased revenues from higher deliveries
due to the colder weather in the 1997 quarter. The decreased revenues for the
1997 six-month period reflect lower gas sales and end user transportation
deliveries primarily due to the warmer weather in the 1997 period as compared to
the same 1996 period, partially offset by an increase in the gas cost recovery
rate. The 1997 twelve-month period increase in revenues is primarily the result
of a gas cost recovery rate increase, substantially offset by lower volumes due
to warmer weather.

*Includes intercompany volumes
 
INTERMEDIATE TRANSPORTATION revenues increased $1.9 million in the quarter and
$5.3 million and $9.3 million in the 1997 six- and twelve-month periods,
respectively. Due primarily to the recent expansion of its northern Michigan
gathering system, MichCon was able to transport an additional 15.3 Bcf, 32.9 Bcf
and 108.8 Bcf in the 1997 quarter, six- and twelve-month periods, respectively.
Intermediate transportation volumes for the 1997 quarter and twelve-month period
were impacted by increased deliveries to two major fixed-fee customers. Volumes
transported in the six-month period for these two customers reflected a
decrease. Although volumes associated with these customers have varied, the
related revenues were not significantly affected.
 
OTHER OPERATING REVENUES increased $2.4 million in the 1997 quarter and $1.4
million in the six-month period due to increased gas processing revenues and
increased revenues associated with maintaining customers' natural gas furnaces
and appliances. Other operating revenues decreased $5.2 million in the 1997
twelve-month period due to

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
          OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)
 
a reduction in conservation revenues resulting from the discontinuance of
MichCon's energy conservation programs which also impacted the quarter and
six-month period. As discussed in the "Operation and Maintenance" section that
follows, this decrease in revenues is offset by a corresponding decrease in
expenses related to the conservation programs.
 
COST OF GAS
 
Cost of gas is affected by variations in sales volumes and cost of gas rates.
Through the Gas Cost Recovery (GCR) mechanism, MichCon's rates are set to
recover 100% of prudently and reasonably incurred gas costs. Therefore,
fluctuations in total gas costs have little or no effect on gross margins and
earnings.
 
Cost of gas sold decreased in the 1997 quarter and six-month period and
increased in the twelve-month period. The decrease in market prices paid for gas
resulted in a decrease in the cost of gas sold per thousand cubic feet of $.49
(16%) in the 1997 three-month period. The increase in market prices paid for gas
resulted in an increase in the cost of gas sold per thousand cubic feet of $.15
(5%) and $.25 (9%) in the 1997 six- and twelve-month periods, respectively. The
rate increase in the 1997 six-month period was more than offset by lower volumes
due to warmer weather. The rate increase in the 1997 twelve-month period was
partially offset by lower volumes due to warmer weather.
 
OTHER OPERATING EXPENSES
 
OPERATION AND MAINTENANCE expenses decreased for the 1997 quarter and increased
for the 1997 six- and twelve-month periods. Operation and maintenance expenses
were affected in all periods by lower benefit costs, primarily pension and
retiree healthcare costs. The 1997 quarter further benefited from a decrease in
uncollectible gas accounts expense, which was partially offset by an increase in
operating expenses related to the increase in intermediate transportation
volumes as previously discussed. For the 1997 six-month period, the decrease in
benefit costs was more than offset by increased operating expenses related to
intermediate transportation services. The increase in the 1997 twelve-month
period is due to higher uncollectible gas accounts expense as well as the
increased operating expenses related to intermediate transportation services. As
previously discussed, the discontinuance of MichCon's energy conservation
programs reduced expenses in all 1997 periods.
 
DEPRECIATION AND DEPLETION for the 1997 quarter, six- and twelve-month periods
increased due to higher plant balances reflecting capital expenditures of $456.8
million over the past two calendar years. Depreciation and depletion expenses
are expected to increase in future years due to additional capital investments.
MichCon filed an application with the MPSC to lower its depreciation rates,
which could partially offset the anticipated increase in depreciation expense in
future years.
 
PROPERTY AND OTHER TAXES increased in the 1997 periods due to an increase in the
Michigan single business tax which is partially offset by a reduction in
property taxes.
 
OTHER INCOME AND DEDUCTIONS
 
The 1997 quarter, six- and twelve-month periods reflect higher interest costs on
increased long-term debt required to finance capital investments in the Gas
Distribution group.
 
INCOME TAXES
 
Income taxes changed primarily as a result of variations in earnings. Income
taxes also were affected by the favorable resolution of prior years' tax issues.

          OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)
 
OUTLOOK
 
Gas Distribution's strategy is to grow revenues and reduce its costs in order to
maintain strong returns and provide customers with quality service at
competitive prices. Revenue growth will be achieved through the expansion of its
residential, commercial and industrial customer base. In 1997, Gas Distribution
is concentrating on adding new customers in current service areas including
increased penetration of previous expansion areas. Gas Distribution will
continue initiatives to increase productivity and improve customer services in
order to strengthen its competitive position in the gas industry. Management is
continually assessing ways to improve cost competitiveness. Among the cost
savings initiatives, Gas Distribution and other Michigan utilities are exploring
opportunities to share the cost of common, duplicative functions in order to
obtain greater efficiencies and increase customer value.
 
DISCONTINUED OPERATIONS
 
In June 1996, MCN completed the sale of its computer operations subsidiary,
Genix, to Affiliated Computer Services, Inc., resulting in an after-tax gain of
$36.2 million. Although Genix had experienced significant growth in revenues and
operating income over the past several years, MCN's focused strategy is to
invest in energy-related projects that generate higher rates of return.
 
CAPITAL RESOURCES AND LIQUIDITY
 
OPERATING ACTIVITIES
 
MCN's cash flow from operating activities increased $76.8 million during the
1997 six-month period from the comparable 1996 period. The increase was due
primarily to higher net income, after adjusting for depreciation, deferred taxes
and nonoperating gains and a decrease in working capital requirements.
 
FINANCING ACTIVITIES
 
In June 1997, MCN sold 9,775,000 shares of common stock in a public offering,
generating net proceeds of $276.6 million (Note 3d). Proceeds from this issuance
were used to fund capital expenditures, to repay short-term obligations and for
general corporate purposes.
 
In June 1997, MCN issued, through wholly owned trusts, 100,000 Private
Institutional Trust Securities and 100,000 Single Point Remarketed Reset Capital
Securities (Note 3c). Net proceeds of $199.1 million from these issuances were
invested by MCN in its Diversified Energy group and were used to reduce
short-term debt incurred to fund capital expenditures. The securities are
currently rated the equivalent of "A-"or "baa1" by the major rating agencies.
 
In March 1997, MCN issued 2,645,000 FELINE PRIDES generating net proceeds of
$127.4 million (Note 3b). Proceeds from the issuance were used to reduce
short-term debt incurred by the Diversified Energy group to fund capital
investments and for general corporate purposes. The FELINE PRIDES are currently
rated the equivalent of "BBB+" by the major rating agencies.
 
MCN issues new shares of common stock pursuant to its Dividend Reinvestment and
Stock Purchase Plan and various employee benefit plans. During 1997, MCN
anticipates the issuance of new shares of common stock pursuant to these plans,
generating approximately $19 million. During the first six months of 1997,
issuances under these plans generated proceeds of $9.4 million.
 
DIVERSIFIED ENERGY
 
In June 1997, MCNIC repaid $30 million of senior debt on its stated maturity
date.
 
In January 1997, MCNIC issued $150 million of medium-term notes using the
proceeds to repay short-term debt and for general corporate purposes.

<PAGE>   11
 
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
          OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)
 
MCNIC has established credit lines for borrowings of up to $100 million under a
364-day revolving credit facility and up to $300 million under a three-year
revolving credit facility, both of which expire in July 1998. These facilities
support MCNIC's $400 million commercial paper program, which is used to finance
capital investments of the Diversified Energy group and working capital
requirements of its gas marketing operations. During the first six months of
1997, MCNIC repaid $329.8 million of commercial paper. At June 30, 1997, there
were no borrowings outstanding under this program. A portion of the credit lines
equaling $42 million has been temporarily restricted in connection with a
potential acquisition by one of MCN's international joint ventures (Note 2a).
 
GAS DISTRIBUTION
 
Cash and cash equivalents normally increase and short-term debt is reduced in
the first part of each year as gas inventories are depleted and funds are
received from winter heating sales. During the latter part of the year, cash and
cash equivalents normally decrease as funds are used to finance increases in gas
inventories and customer accounts receivable. To meet its seasonal short-term
borrowing needs, MichCon normally issues commercial paper which is backed by
credit lines with several banks. MichCon has established credit lines to allow
for borrowings of up to $150 million under a 364-day revolving credit facility
and up to $150 million under a three-year revolving credit facility. During the
first six months of 1997, MichCon repaid $238.3 million of commercial paper. At
June 30, 1997, there were no borrowings outstanding under this program.
 
During May 1997, MichCon issued $85 million of first mortgage bonds under its
existing shelf registrations. The funds from this issuance were used to retire
first mortgage bonds, fund capital expenditures and for general corporate
purposes.
 
During April 1997, subsidiaries of MichCon borrowed $40 million under a
nonrecourse credit agreement that matures in 2005. Proceeds were used to finance
the expansion of the northern Michigan gathering system.
 
During May and June 1997, MichCon redeemed $17 million of long-term debt prior
to maturity. MichCon also repaid $50 million of first mortgage bonds on its
stated maturity date in May 1997.
 
MichCon has available a Trust Demand Note program that allows it to borrow up to
$25 million. At June 30, 1997, there were no borrowings outstanding under this
program.
 
INVESTING ACTIVITIES
 
Capital investments increased $120.6 million (39%) in the 1997 six-month period
over the same period in 1996. The 1997 investments include higher levels of
investments in E&P properties and joint venture pipeline facilities as well as
the acquisition of an interest in Indian power generation projects and a
domestic cogeneration facility. The 1996 investments include the DIGP
acquisition. In the third quarter of 1997, MCN

sold E&P assets for approximately $31 million. The proceeds from the sale will
be reinvested in E&P operations, primarily in offshore properties.

OUTLOOK
 
Capital investments in 1997 are expected to reach $1.1 billion -- MCN's
strategic direction is to grow significantly by investing in a portfolio of
energy-related projects. For 1997, MCN anticipates investing approximately $900
million in Diversified Energy and the remainder in Gas Distribution. Within
Diversified Energy, approximately $450 million will be invested in E&P projects
for drilling operations and the acquisition of additional reserves. Diversified
Energy will invest the remaining $450 million in gas gathering, gas processing
and power generation projects.
 
As MCN continues to pursue its strategy of diversifying through a portfolio of
energy-related projects, it will routinely evaluate the value and strategic
benefits of selling its assets. MCN is currently negotiating the sale of certain
Diversified Energy assets to unlock their appreciated value. Proceeds from any
sale will be used to acquire or develop other energy-related assets and
therefore capital investments would be increased accordingly.
 
The proposed level of investments for the remainder of 1997 increases capital
requirements materially in excess of internally generated funds and requires the
issuance of additional debt. MCN's actual capital requirements and general
market conditions will dictate the nature, timing and amount of future
issuances. It is management's opinion that MCN and its subsidiaries will have
sufficient capital resources, both internal and external, to meet anticipated
capital requirements.
 
In August 1997, President Clinton signed a bill that will reduce taxes collected
by the United States over the next five years. MCN is currently assessing the
exact impact of this legislation on its future tax liabilities. Although the
bill is not expected to significantly change MCN's tax expense, it will have an
impact on the timing of tax payments. It is anticipated that MCN will realize a
significant benefit in cash flows from a deferral in taxes paid over the next
five years as a result of this legislation.

          OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Concluded)
 
NEW ACCOUNTING PRONOUNCEMENTS
 
In February 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings per Share"
and SFAS No. 129, "Disclosure of Information about Capital Structure", which are
effective for MCN's year end 1997 financial statements. SFAS No. 128 simplifies
the standards for computing earnings per share (EPS), replaces primary EPS with
a newly defined basic EPS and modifies the computation of diluted EPS. SFAS No.
129 continues previous requirements to disclose certain information about an
entity's capital structure. MCN does not expect the application of these
statements to have a material effect on its financial statements.
 
In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income" and
SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information" which are effective for financial statements for periods beginning
after December 15, 1997. SFAS No. 130 establishes standards for reporting and
display of comprehensive income and its components. SFAS No. 131 establishes
standards for reporting information about operating segments in annual and
interim financial statements. MCN is in the process of evaluating the effect of
applying these statements.
 
In 1996, the Emerging Issues Task Force of the FASB reached a consensus that the
cost associated with modifying internal use software for the year 2000 should be
expensed as incurred. MCN has established processes for evaluating and managing
the risks and costs associated with this issue on the financial position and
results of operations of MCN and its subsidiaries. MCN is assessing the extent
of necessary modifications to its computer software, as well as that of its
partners and operators.
 
FORWARD-LOOKING STATEMENTS
 
Statements included throughout the Quarterly Report on Form 10-Q which are not
historical in nature are forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. Forward-looking statements
involve certain risks and uncertainties that may cause actual future results to
differ materially from those contemplated, projected, estimated or budgeted in
such forward-looking statements including, among others, the following: (i) the
effects of weather and other natural phenomena; (ii) increased competition from
other energy suppliers as well as alternative forms of energy; (iii) the capital
intensive nature of MCN's business; (iv) economic climate and growth in the
geographic areas in which MCN does business; (v) the uncertainty of gas and oil
reserve estimates; (vi) the timing and extent of changes in commodity prices for
natural gas, electricity and crude oil; (vii) the nature, availability and
projected profitability of potential projects and other investments available to
MCN; (viii) conditions of capital markets and equity markets and (ix) changes in
the economic and political climate in foreign countries where MCN has invested
or may invest in the future.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
 
1. GENERAL
 
The accompanying consolidated financial statements should be read in conjunction
with MCN's 1996 Annual Report on Form 10-K. Certain reclassifications have been
made to the prior year's financial statements to conform with the 1997
presentation. In the opinion of management, the unaudited information furnished
herein reflects all adjustments (consisting of only recurring adjustments or
accruals) necessary for a fair presentation of the financial statements for the
periods presented.
 
Because of seasonal and other factors, revenues, expenses, net income and
earnings per share for the interim periods should not be construed as
representative of revenues, expenses, net income and earnings per share for all
or any part of the balance of the current year or succeeding periods.
 
2. ACQUISITIONS AND DISPOSITIONS
     
     a. TORRENT POWER PRIVATE LIMITED
 
     In March 1997, MCN acquired a 40% interest in Torrent Power Private Limited
     (TPPL), an India joint venture that holds minority interests in electric
     companies and power generation facilities located in the state of Gujarat,
     India. The total cost of the acquisition was approximately $57,000,000, of
     which $50,400,000 was paid through June 1997. The remainder is expected to
     be paid in the second half of 1997. Specifically, the joint venture has a
     21% interest in Ahmedabad Electricity Company Limited (AEC), a 43% interest
     in Surat Electricity Company Limited (SEC) and a 30% interest in Gujarat
     Torrent Energy Corporation (GTEC). AEC serves the city of Ahmedabad and has
     550 megawatts (MW) of electric generating capacity. SEC provides
     electricity to the city of Surat. GTEC is currently constructing a 655 MW
     dual fuel generation facility, the first phase of which is expected to be
     operational in late 1997 and fully completed by the end of 1998. In
     addition to equity investments, the construction of this facility will be
     funded through nonrecourse project financing of which the portion
     attributable to MCN's existing interest will be approximately $60,000,000.
 
     In June 1997, MCN entered into an agreement to obtain a sufficient number
     of preference shares in TPPL to meet TPPL's cash requirements to acquire
     additional interests in AEC and GTEC. In August 1997, TPPL acquired an
     additional 10% interest in AEC for $21,000,000. In the second half of 1997,
     TPPL will make a public offer to AEC's shareholders to acquire up to an
     additional 20% interest in AEC for approximately $42,000,000. TPPL is
     currently negotiating to acquire further interests in AEC and GTEC.
 
     b. MIDLAND COGENERATION VENTURE LIMITED PARTNERSHIP
 
     During the second quarter of 1997, MCN purchased an 18.1% general
     partnership interest in Midland Cogeneration Venture Limited Partnership
     (MCV), a partnership that leases and operates a cogeneration facility in
     Midland, Michigan. The facility can produce up to 1,370 MW of electricity,
     as well as 1.35 million pounds per hour of process steam. The investment
     totaled $54,750,000 and is accounted for under the equity method.
 
     c. DAUPHIN ISLAND GATHERING PARTNERS
 
     As discussed in MCN's 1996 Annual Report on Form 10-K, MCN acquired in the
     first quarter of 1996 a 99% interest in Dauphin Island Gathering Partners
     (DIGP), a general partnership that owns a 90-mile gas gathering system in
     the Mobile Bay area of offshore Alabama. In June of 1996, MCN sold a 35%
     interest in DIGP for a pre-tax gain of $3,488,000. An additional 5%
     interest was sold in the third quarter of 1996, generating a pre-tax gain
     of $498,000. In December 1996, a 41% interest in the partnership was sold
     to three additional partners resulting in a pre-tax gain of $4,796,000, of
     which $2,398,000 was deferred until the third quarter of 1997 when the
     related option agreement expired unexercised.

     D. THE GENIX GROUP, INC.
 
     As discussed in MCN's 1996 Annual Report on Form 10-K, MCN completed the
     sale of its computer operations subsidiary, The Genix Group, Inc., to
     Affiliated Computer Services, Inc. in June 1996. The sale resulted in an
     after-tax gain of $36,176,000.
 
3. CAPITALIZATION
 
     A. LONG-TERM DEBT
 
     The following long-term debt was issued during the first half of 1997 (in
     thousands):

                 6.89%, due January 2002        $90,000
                 7.12%, due January 2004        $60,000
- ----------------------------------------------------------
May 1997       MichCon First Mortgage Bonds
                 7.21%, due May 2007            $30,000
                 7.06%, due May 2012            $40,000
                 7.60%, due May 2017            $15,000
- ----------------------------------------------------------
</TABLE>
 
     During April 1997, MichCon subsidiaries borrowed $40,000,000 under a
     nonrecourse credit agreement at an average interest rate of 6.45%. Under
     the terms of the agreement, certain alternative variable interest rates are
     available at the borrowers' option during the life of the agreement.
     Quarterly principal payments commenced in June 1997 with the final
     installment due November 2005. The loan is secured by a pledge of the stock
     of the borrowers and a security interest in certain of their assets.
 
     MichCon entered into variable interest rate swap agreements with notional
     principal amounts aggregating $80,000,000 in connection with the first
     mortgage bonds issued in May 1997. Swap agreements of $40,000,000 through
     May 2002 have reduced the average cost of debt from 7.31% to 6.30% for the
     two months ended June 30, 1997. Swap agreements of $40,000,000 through May
     2005 have reduced the average cost of debt from 7.06% to 5.90% for the two
     months ended June 30, 1997.
 
     In the second quarter of 1997, MichCon redeemed early $5,000,000 of 9.5%
     first mortgage bonds and $12,000,000 of 9.75% unsecured notes. As discussed
     in MCN's 1996 Annual Report on Form 10-K, MichCon had a variable interest
     rate swap through April 2000 on the $12,000,000 unsecured notes. This
     agreement reduced the cost of debt of the fixed-rate unsecured notes from
     9.75% to 5.77% for the six months ended June 30, 1997. This swap has been
     redesignated as a hedge of other outstanding first mortgage bonds.
 
     B. FELINE PRIDES
 
     In March 1997, MCN issued 2,645,000 FELINE PRIDES yielding 8% with a stated
     amount of $50 per security. Each security initially consists of a stock
     purchase contract and a preferred security of MCN Financing III.
 
     Under each stock purchase contract, MCN is obligated to sell and the FELINE
     PRIDES holder is obligated to purchase in May 2000 for $50, between 1.4132
     and 1.7241 shares of MCN common stock. The exact number of MCN common
     shares to be sold is dependent on the market value of a share in May 2000,
     but will not be less than 3,737,988 or more than 4,560,345 shares. MCN is
     also obligated to pay the FELINE PRIDES holders a quarterly contract
     adjustment payment at an annual rate of .75% of

     the stated amount. MCN has recorded the present value of the contract
     adjustment payments, totaling $2,661,015, as a liability and a reduction to
     Common Shareholders' Equity on MCN's Consolidated Statement of Financial
     Position. The liability is reduced as the contract adjustment payments are
     made. MCN has the right to defer the contract adjustment payments, in which
     case MCN cannot declare dividends on its common stock until the contract
     adjustment payments have been made. In addition, MCN has incurred costs of
     approximately $4,900,000 in conjunction with the issuance and similarly has
     recorded these costs as a reduction to Common Shareholders' Equity.
 
     MCN Financing III, a business trust wholly owned by MCN, was formed for the
     sole purpose of issuing preferred securities and lending the gross proceeds
     thereof to MCN. In March 1997, the trust issued 2,645,000 shares of 7.25%
     redeemable preferred securities, at the liquidation preference value of $50
     per share. The trust invested the $132,250,000 of gross proceeds from the
     issuance of the preferred securities, as well as $4,090,250 of proceeds
     from the issuance of common securities to MCN, in an equivalent amount of
     7.25% Junior Subordinated Debentures of MCN. The $136,340,250 of Junior
     Subordinated Debentures are due May 2002 and are the sole assets of the
     trust. Upon maturity of the debentures, the trust is required to redeem the
     preferred securities.
 
     Holders of the preferred securities are entitled to receive cumulative
     dividends at an annual rate of 7.25% of the liquidation preference value.
     Dividends are payable quarterly and in substance are tax deductible by MCN.
     MCN has the right to extend interest payment periods on the debentures for
     successive periods through the May 2002 maturity date. As a consequence,
     quarterly dividend payments on the preferred securities can be deferred by
     the trust during any such interest payment period. In the event that MCN
     exercises this right, MCN may not declare dividends on its common stock.
 
     In the event of default, holders of the preferred securities will be
     entitled to exercise and enforce the trust's creditor rights against MCN,
     which may include acceleration of the principal amount due on the
     debentures. MCN has issued a guaranty with respect to payments on the
     preferred securities. This guaranty, taken together with MCN's obligations
     under the debentures, the related indenture, and the trust documents,
     provides a full and unconditional guaranty of the trust's obligations under
     the preferred securities to the extent the trust has funds available
     therefor.
 
     The preferred securities are pledged as collateral to secure the FELINE
     PRIDES holders' obligation to purchase MCN common stock under the stock
     purchase contracts. Each holder has the right after issuance of the FELINE
     PRIDES to substitute for the preferred securities, zero coupon U.S.
     Treasury Securities maturing in May 2000. Each FELINE PRIDES holder has the
     option to use the preferred securities or the treasury securities to
     satisfy the May 2000 purchase contract commitment.
 
     C. PREFERRED SECURITIES
 
     In 1997, MCN Financing V and MCN Financing VI, business trusts wholly owned
     by MCN, were formed for the sole purpose of issuing preferred securities
     and lending the gross proceeds thereof to MCN. In June 1997, MCN Financing
     V issued 100,000 Private Institutional Trust Securities (PRINTS) and MCN
     Financing VI issued 100,000 Single Point Remarketed Reset Capital
     Securities (SPRRCS), both at their liquidation preference value of $1,000
     per security. The trusts invested the $200,000,000 of gross proceeds from
     the issuances of the preferred securities, as well as $6,186,000 of
     proceeds from the issuances of common securities to MCN, in an equivalent
     amount of senior debentures of MCN. The $206,186,000 of senior debentures
     are due 2037, are on terms substantially the same as the preferred
     securities and are the sole assets of the trusts.
 
     The preferred securities are structured such that at a specified future
     date, the rate reset date, the securities may be remarketed with a new
     liquidation preference value of $25 per security. The annual dividend
     payment rate will be reset to reflect the lowest rate, less than or equal
     to a maximum rate, at which the securities can be remarketed at a price
     equal to their liquidation preference value. On the rate
 
                                       17
<PAGE>   20
 
                     MCN ENERGY GROUP INC. AND SUBSIDIARIES
           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)
 
     reset date, the terms of an equivalent amount of the MCN senior debentures
     will change to reflect the new terms of the remarketed preferred
     securities. The debentures will thereafter be subordinated and junior in
     right of payment to all senior obligations of MCN. The rate reset dates for
     the PRINTS and SPRRCS are anticipated to be June 1, 1998 and October 28,
     1999, respectively.
 
     Prior to the rate reset date, holders of the PRINTS and SPRRCS are entitled
     to receive cumulative dividends at annual rates of 6.305% and 6.85% of the
     liquidation preference value, respectively. Dividends are in substance tax
     deductible by MCN and are payable semi-annually until the rate reset date,
     after which they will become payable quarterly. Financing costs were
     deferred and reflected as a reduction in the carrying value of the
     preferred securities. These costs are being amortized using the
     straight-line method over 40 years.
 
     Subsequent to the rate reset date, MCN has the right to extend interest
     payment periods on the debentures for up to 20 consecutive quarters through
     the June 2037 maturity date. As a consequence, dividend payments on the
     preferred securities can be deferred by the trusts during any such interest
     payment period. In the event that MCN exercises this right, MCN may not
     declare dividends on its common stock. With MCN's consent, the preferred
     securities are redeemable at the option of the trusts, in whole or in part,
     on the rate reset date or at any time after the fifth anniversary of the
     rate reset date. In addition, upon maturity of the debentures, the trusts
     are required to redeem the preferred securities.
 
     In the event of default, holders of the preferred securities will be
     entitled to exercise and enforce the trust's creditor rights against MCN,
     which may include acceleration of the principal amount due on the
     debentures. MCN has issued guaranties with respect to payments on the
     preferred securities. These guaranties, when taken together with MCN's
     obligations under the debentures, the related indenture, and the trust
     documents, provide full and unconditional guaranties of the trusts'
     obligations under the preferred securities.
 
     In June 1997, MCN entered into a one-year variable interest rate swap
     agreement with a notional amount of $100,000,000. The swap agreement
     effectively reduced the PRINTS fixed dividend rate from 6.305% to 5.94%
     through June 30, 1997.
 
     D. COMMON STOCK AND ADDITIONAL PAID-IN CAPITAL
 
     In June 1997, MCN sold 9,775,000 shares of new common stock in a public
     offering, generating net proceeds of $276,600,000.
 
     Under the MCN Shareholder's Rights Plan, one preferred share purchase right
     is attached to each outstanding share of common stock. In July 1997, the
     MCN Board of Directors amended the Plan which, among other changes,
     extended the expiration of the rights to July 2007. The rights, which
     cannot be traded separately from MCN's common stock, are designed to
     protect shareholders from coercive or unfair tactics and are therefore
     exercisable only upon certain triggering events.
 
4. LINES OF CREDIT
 
As discussed in MCN's 1996 Annual Report on Form 10-K, MichCon and MCNIC
maintain credit lines that allow for borrowings of up to $250,000,000 under
364-day revolving credit facilities and up to $450,000,000 under three-year
revolving credit facilities. These credit lines, totaling $700,000,000, support
their commercial paper programs. No borrowings were outstanding under these
lines as of June 30, 1997. The 364-day revolving credit facilities were renewed
in July 1997. The three-year revolving credit facilities expire in July 1998.
 
In July 1997, the MCNIC Board of Directors approved a resolution to temporarily
restrict $42,000,000 of the MCNIC credit facility to support TPPL's public offer
to purchase additional interest in AEC (Note 2a).

5. GAS IN INVENTORY
 
Inventory gas is priced on a last-in, first-out (LIFO) basis. In anticipation
that interim inventory reductions will be replaced prior to year end, the cost
of gas for net withdrawals from inventory is generally recorded at the estimated
average purchase rate for the calendar year. The excess of these charges over
the LIFO cost is credited to the gas inventory equalization account. During
interim periods when there are net injections to inventory, the equalization
account is reversed. Approximately 51.2 billion cubic feet (Bcf) and 49.7 Bcf of
gas was in inventory at June 30, 1997 and 1996, respectively.
 
6. COMMODITY SWAP AGREEMENTS
 
As discussed in MCN's 1996 Annual Report on Form 10-K, MCN manages commodity
price risk through the use of various derivative instruments and limits the use
of such instruments to hedging activities. If MCN did not use derivative
instruments, its exposure to such risk would be higher. Although this strategy
reduces risk, it also limits potential gains from favorable changes in commodity
prices. Natural gas and oil swap agreements are used to manage exposure to the
risk of market price fluctuations on gas sale contracts and gas and oil
production. Market value changes of swap contracts are recorded as deferred
gains or losses until the hedged transactions are completed, at which time the
realized gains or losses are included as adjustments to revenues. The offsets to
the unrealized losses are recorded as deferred payables and the offsets to the
unrealized gains are recorded as deferred receivables.
 
The following assets and liabilities related to the use of gas and oil swap
agreements are reflected in the Consolidated Statement of Financial Position:

7. COMMITMENTS AND CONTINGENCIES
 
In July 1997, MCN's 50%-owned partnership, Washington 10 Storage Partnership
(W-10), entered into a leveraged lease transaction to finance the conversion of
a depleted natural gas reservoir into a 42 Bcf storage facility. The storage
facility is expected to begin operations in mid-1999 and cost $160,000,000. MCN
has entered into a contract with W-10 to market 100% of the capacity of the
storage field through 2029. Under the terms of the marketing contract, MCN is
obligated to generate sufficient revenues to cover W-10's lease payments and
certain operating costs, which average approximately $16,000,000 annually. As of
June 30, 1997, MCN has long-term contracts in place for approximately 40% of the
field's capacity thereby reducing its commitments under the marketing contract.
A significant portion of the remaining capacity is expected to be contracted by
MCN's Energy Marketing operations, thereby enhancing its ability to offer a
reliable gas supply during peak winter months.

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)
 
MCN is involved in certain legal and administrative proceedings before various
courts and governmental agencies concerning claims arising in the ordinary
course of business. Management cannot predict the final disposition of such
proceedings, but believes that adequate provision has been made for probable
losses. It is management's belief, after discussion with legal counsel, that the
ultimate resolution of those proceedings still pending will not have a material
adverse effect on MCN's financial statements.
 
8. CONSOLIDATING FINANCIAL STATEMENTS
 
Debt securities issued by MCNIC are subject to a support agreement between MCN
and MCNIC, under which MCN has committed to make payments of interest and
principal on MCNIC's securities in the event of failure to pay by MCNIC. Under
the terms of the support agreement, the assets of MCN, other than MichCon, and
any cash dividends paid to MCN by any of its subsidiaries are available as
recourse to holders of MCNIC's securities. The carrying value of MCN's assets on
an unconsolidated basis, primarily investments in its subsidiaries other than
MichCon, is $1,075,459,000 at June 30, 1997.
 
The following MCN consolidating financial statements are presented and include
separately MCNIC, MichCon and MCN and other subsidiaries. MCN has determined
that separate financial statements and other disclosures concerning MCNIC are
not material to investors. The other MCN subsidiaries represent Citizens Gas
Fuel Company, Blue Lake Holdings, Inc., MCN Michigan Limited Partnership, MCN
Financing I, MCN Financing III, MCN Financing V and MCN Financing VI.

 (1) Earnings and fixed charges are defined and computed in accordance with
     Item 503 of Regulation S-K.

 (2) This amount represents the aggregate of (a) the pre-tax income from
     continuing operations of MCN and its majority-owned subsidiaries, (b)
     MCN's share of pre-tax income of its 50% owned companies, and (c) any
     income actually received from less than 50% owned companies.

 (3) Fixed charges added to earnings are adjusted to exclude interest
     capitalized during the period for nonutility companies and the preferred
     securities dividend requirements of MichCon included in fixed charges but
     not deducted in the determination of pre-tax income.

 (4) Fixed charges represent (a) interest, whether expensed or capitalized, (b)
     amortization of debt discount, premium and expense, (c) an estimate of
     interest implicit in rentals, and (d) preferred securities dividend
     requirements of subsidiaries, increased to reflect the pre-tax earnings
     requirement for MichCon.

(5)  In June 1996, MCN completed the sale of  The Genix Group, its computer
     operations subsidiary.  For purposes of calculating the Ratio of Earnings
     to Fixed Charges, it has been classified as a discontinued operation and
     therefore excluded from the ratio for all periods presented.

  (1)  Earnings and fixed charges are defined and computed in accordance with
       Item 503 of Regulation S-K.

  (2)  This amount represents the aggregate of (a) the pre-tax income from
       continuing operations of MCN Investment and its majority-owned
       subsidiaries, (b) MCN Investment's share of pre-tax income of its 50%
       owned companies, and (c) any income actually received from less than 50%
       owned companies.

  (3)  Fixed charges added to earnings are adjusted to exclude interest
       capitalized during the period.

  (4)  In June 1996, MCN completed the sale of The Genix Group, its computer
       operations subsidiary.  For purposes of calculating the Ratio of
       Earnings to Fixed Charges, it has been classified as a discontinued
       operation and therefore excluded from the ratio for all periods
       presented.

merging with the MCN Corporation Deferred Fee Plan.  The title of the amended
plan shall be the "MCN Energy Group Inc. Nonemployee Directors' Compensation

Shares in cash or Company common stock prior to his Retirement Date. The shares
awarded pursuant to this Plan shall be in addition to, and not in lieu of, an
Eligible Board Member's annual retainer fee or other compensation payable to
each Eligible Board Member as a result of his or her service on the Board of

forth in Section 6.01 of the Plan, not to exceed .03 percent of the total
number of outstanding shares of MCN Energy Group Inc. common stock as of the
first day of the Plan Year.  Shares to be issued under the Plan may be
authorized and unissued shares or authorized and issued shares of common stock

Provided, however, that the number of shares that may be issued under this Plan
may not exceed 1% of the number of shares issued and outstanding on March 1,

     6.04. Capital Adjustments.  The aggregate number and class of shares
subject to and authorized by the Plan shall be proportionately adjusted for any

consolidation, reorganization or any similar capital adjustment or other
increase or decrease in the number of outstanding shares effected without
receipt of consideration by the Company.

                            DEFERRAL OF RETAINER FEE

     7.01. Election of Deferral.  A Participant may elect, in his Deferral
Election Agreement, to defer all or a portion of his cash retainer fee for each
Plan Year in which he is a Participant. Such annual Deferral shall not exceed
the Participant's Covered Compensation. Except as provided in Section 10.04(C),
a Participant's election to defer all or a portion of his cash retainer fee for
a Plan Year shall be irrevocable for that Plan Year.  A Participant shall
indicate on his Deferral Election Agreement whether his Deferral will be
credited to his Cash Deferral Account or his Performance Share Deferral
Account.  Except as provided in Section 7.04, once an amount has been credited
to the Cash Deferral Account or the Performance Share Account, such amounts may
not subsequently be transferred to the other account.

     7.02. Establishment of a Cash Deferral Account.  If a Participant so
elects on his Deferral Election Agreement, the Committee shall establish a Cash
Deferral Account for such Participant to which (i) the Participant's Deferrals
shall be credited; and (ii) the Participant's account balance, if any, under
the Prior Plan shall be credited in accordance with Section 5.01.

     7.03. Deferrals.  A Participant may continue to make the annual Deferral
provided under Section 7.01 with respect to his Deferral Election Agreement
until he resigns or is otherwise removed from his membership on the Board of
Directors, or he receives a hardship withdrawal.

     7.04 Deferrals Limited By Section 6.03.  If a Participant elects in his
Deferral Election Agreement to have his Deferral credited to his Performance
Share Deferral Account and such election is limited due to Section 6.03, the
amount of the Participant's Deferral that cannot be credited to his Performance
Share Deferral Account due to Section 6.03 ("Limited Deferral") shall be
credited to the Participant's Cash Deferral Account.  The amount of the Limited
Deferral shall be denoted by a bookkeeping entry.  At such time as the limits
of Section 6.03 permit, the Limited Deferral, plus interest equivalents at the
Plan Interest Rate, shall be transferred from the Participant's Cash Deferral
Account to his Performance Share Deferral Account.  The amount transferred
shall be converted to a number of common stock equivalents equal to the average
of

                                       8

the high and low of the Company common stock price on the New York Stock
Exchange Composite Tape for the trading day preceding the day on which a credit
to this Plan is to be made.

                              FUNDING OF BENEFITS

     8.01. Unfunded Plan.  The Plan shall be unfunded. All benefits payable
under the Plan shall be paid from the Company's general assets.  The Company
shall not be required to set aside or hold in trust any funds for the benefit
of a Participant or Beneficiary, who shall have the status of a general
unsecured creditor with respect to the Company's obligation to make benefit
payments pursuant to the Plan.  Any assets of the Company available to pay Plan
benefits shall be subject to the claims of the Company's general creditors and
may be used by the Company in its sole discretion for any purpose.

     8.02. Interest.  Interest shall be credited and compounded monthly to each
Participant's Cash Deferral Account during each Plan Year based upon the Plan
Interest Rate in effect for such Plan Year for so long as there remains a Cash
Deferral Account balance.

     8.03 Dividend Equivalents.   Dividend equivalents equal to 50% of the
dividend rate payable on Company common stock shall be credited to a
Participant's Performance Share Deferral Account based on the number of
Performance Shares in such Participant's Performance Share Deferral Account.
Dividend equivalents shall be reinvested in Performance Shares based upon the
average of the high and low of the Company common stock price on the dividend
payment date.

                                CLAIMS PROCEDURE

the deceased Participant.  In the event of a Participant's death, a certified
copy of the death certificate will be required by the Committee.  The Committee
reserves the right to require that the Participant furnish proof of his age
prior to processing any application.  Each application shall be acted upon and
approved or disapproved within ninety (90) days following its receipt by the
Committee. In the event any application for benefits is denied in whole or in

specific references to pertinent Plan provisions on which the denial is based,
a description of any additional material or information necessary for the
applicant to perfect his application, an explanation of why such material or
information is necessary, and an explanation of the Plan's review procedure.

     9.02. Appeals Procedure.  Any person or his duly authorized representative
whose application for benefits is denied in whole or in part may appeal such
denial to the Committee for a review of the decision by submitting to the
Committee at the Company's principal place of business within ninety (90) days

written statement:

            (a)  requesting a review by the Committee of his
                 application for benefits;

            (c)  setting forth any issues or comments that the
                 applicant deems pertinent to his application.

     The Committee shall act upon each application within sixty (60) days after
receipt of the applicant's request for review by the Committee.

     The Committee shall make a full and fair review of each such application
and any written materials submitted by the applicant or the Company in
connection therewith and may require the Company or the applicant to submit
such additional facts, documents, or other evidence as the Committee in its
sole discretion deems necessary or advisable in making such a review.  On the
basis of its review, the Committee shall make an independent determination of
the applicant's eligibility for benefits under the Plan.  The decision of the
Committee on any application for benefits shall be final and conclusive upon
all persons.

                                   SECTION 10
                           FORM AND TIMING OF PAYMENT

     10.01. Normal Retirement Benefit.  Each Participant who retires on his
Retirement Date shall be entitled to a Retirement Income Benefit commencing on
the first of the month following the month in which his Retirement Date occurs
("Valuation Date"). As of the Valuation Date, the Participant's Account shall
be valued on a cash basis, using the average of the high and low of the Company
common stock price on the New York Stock Exchange Composite Tape on the day
before valuation is made, with interest credited monthly at the Plan Interest
Rate.  Notwithstanding the fact that a Participant's Account will be valued on
a cash basis as of the Valuation Date, the distribution to a Participant of the
amount in his Performance Share Deferral Account shall be paid in Company
common stock equal to the number of shares of Company common stock deemed to be
held in the Participant's Account and valued at the average of the high and low
price of MCN Energy Group Inc. common stock on the New York Stock Exchange
Composite Tape on the day before payment is made.  Payment of the vested
portion of a Participant's accounts shall be made in accordance with the
Participant's selection on his Benefit Agreement in monthly payments in one
year increments not to exceed 15 years, or as a lump sum distribution of the
Participant's Account.  The amount of the monthly payments shall be calculated
to pay out over the specified period the entire balance in the Participant's
Account as of his Retirement Date with interest credited monthly on the
declining balance at the Plan Interest Rate.  The Participant's Account shall
continue to be credited monthly with interest at the Plan Interest Rate and
charged with the monthly payments to the Participant.  The amount of the
monthly payments to the Participant shall be adjusted on January 1 of each year
to reflect changes in the Plan Interest Rate and other changes in the
Participant's Account balance.


                                       11


<PAGE>   16




     10.02. Change in Payment Option.  A Participant's payment election may be
changed at any time by the Participant submitting a new payment selection to
the Committee, but any change received by the Committee less than twelve months
prior to the Participant's Retirement Date shall be void.

     10.03. Termination Benefit.  A Participant who ceases to be an Eligible
Board Member prior to his Retirement Date shall receive payment of the
Participant's Account balance in accordance with the Participant's selection on
his Payment Election Form, either in monthly payments in one year increments
not to exceed 15 years, or as a lump sum distribution in an amount equal to the
Participant's Account.  Payment of a Participant's termination benefit shall
begin no later than one hundred twenty (120) days after the Participant ceases
to an Eligible Board Member.  After receiving a termination benefit, neither
the Participant, nor his spouse or Beneficiary shall be entitled to any further
benefit hereunder.

     10.04. Hardship Withdrawal Benefit.
           (A) At any time prior to the commencement of Retirement Income
      Benefits hereunder, a Participant may request that the Committee make a
      distribution to him of his Cash Deferral Account balance in a lump-sum
      within 30 days.  Such distribution shall be made only if the Committee
      determines that the Participant is suffering from a financial hardship
      that cannot be satisfied from his normal sources of income.

           (B) Financial hardship is limited to the amount required to meet the
      need created by any of the following situations:

                  1.   Financial obligations incurred by the
                       Participant on account of death or disability in the
                       immediate family, which obligations the Participant is
                       not able to pay out of liquid assets or current cash
                       flow.

                  2.   Inability to purchase out of liquid
                       assets, current cash flow, or otherwise reasonably
                       finance the purchase of necessary shelter, utilities,
                       equipment, furnishings and other necessities for the
                       Participant's immediate family.

                                       12


<PAGE>   17




                  3.   Inability to pay out of liquid assets, current cash 
                       flow or otherwise reasonably finance, educational 
                       expenses for a member of the Participant's immediate 
                       family.

           (C) For the 24-month period beginning on the first of the month
      after receiving the hardship distribution, a Participant shall not be
      eligible to defer any portion of the retainer fee under Section 7.01.
      After receiving a hardship distribution in a Plan Year, neither the
      Participant, nor his Spouse or Beneficiary shall be entitled to any
      further benefit hereunder unless the Participant completes two years of
      participation after the hardship distribution, in which event the
      Pre-Retirement Survivor Benefit shall be based solely on Deferrals after
      the hardship distribution.  If a Participant dies during the two years of
      participation after the hardship distribution, the Pre-Retirement
      Survivor Benefit shall be computed as provided in Section 11.01, except
      that the projection forward shall include hypothetical annual Deferrals
      equal to zero.

                                   SECTION 11
                        PRE-RETIREMENT SURVIVOR BENEFITS

     11.01. Pre-Retirement Survivor Benefit.  If a Participant dies prior to
his Retirement Date, his Beneficiary shall be entitled to receive an amount
equal to the Participant's Account balance as follows:

     (A) Cash Deferral Account.  The benefit from the Cash Deferral Account
shall be equal to the present value, at the Participant's date of death, of the
Participant's Cash Deferral Account projected forward to his Retirement Date.
This projection forward will be accomplished by valuing the Participant's Cash
Deferral Account as of the date of the Participant's death, crediting to his
Cash Deferral Account balance as of his date of death the amount of his annual
Deferral, if any, for the year of his death and for all subsequent years
through and including the year in which his Retirement Date falls and crediting
interest on the Account balance and projected Deferrals at the Plan Interest
Rate on his date of death in order to arrive at the projected value of his Cash
Deferral Account balance as of his Retirement Date.  This projected Cash
Deferral Account balance then will be converted to its present value on the
Participant's date of death using 70% of the Plan Interest Rate on the
Participant's date of death.

                                       13


<PAGE>   18




     (B) Performance Share Deferral Account.  The Participant's Performance
Share Deferral Account will be valued on a cash basis as of the date of the
Participant's death.   Notwithstanding such cash valuation, the distribution to
a Beneficiary of the amount in the Participant's Performance Share Deferral
Account shall be paid in Company common stock equal to the number of shares of
Company common stock deemed to be held in the Participant's Account.

     (C) Payment.  The pre-retirement survivor benefit shall be paid, in
accordance with the Participant's selection in his Benefit Agreement, either in
equal monthly payments in one year increments not to exceed 15 years, or as a
lump sum distribution of the Participant's Account.

     11.02 Proof of Insurability.  If a new Participant is uninsurable, or does
not cooperate in the application for life insurance, such Participant's
Beneficiary shall not be entitled to receive a Pre-Retirement Survivor Benefit
under Section 11.01(A).  The Beneficiary of such a Participant shall receive a
distribution of an amount equal to the Participant's Account balance as of the
Participant's date of death.  Such distribution shall be paid in accordance
with the Participant's selection on his Benefit Agreement, either in monthly
payments in one year increments not to exceed 15 years, or as a lump sum
distribution.

     If a Participant, who was insurable at the time participation in the Plan
commenced, elects to increase his Deferral, such increase shall not be
reflected in computing the Pre-Retirement Survivor Benefit under Section
11.01(A) if the Participant became uninsurable prior to electing the increased
Deferral or does not cooperate in the application for life insurance.

     11.03. Exclusion for Suicide or Self-Inflicted Injury.  Notwithstanding
any other provision of the Plan, no Pre-Retirement Survivor Benefits in excess
of a Participant's Account balance as of his date of death shall be paid to any
Participant or Beneficiary in the event the Participant dies as the result of
suicide or self-inflicted injury within two years after January 1 of the first
year of participation.

                       POST-RETIREMENT SURVIVOR BENEFITS

     12.01. Post-Retirement Survivor Benefit.  The Beneficiary, other than the

     15.02. Right to Suspend.  If the Board of Directors determines that
payments under the Plan would have a material adverse affect on the Company's
ability to carry on its business, the Board of Directors may suspend such

shall pay such suspended payments in a lump sum immediately upon the expiration
of the period of suspension.

     15.03. Non-ERISA Plan. The Plan is intended to provide benefits for
Eligible Board Members who are not employees of the Company and, therefore, to

option of the Board of Directors, may be accelerated and the balance paid in a
single, actuarially equivalent lump-sum), no further benefits shall be paid
hereunder in the event it is determined by a court of competent jurisdiction or

                                       16


<PAGE>   21



counsel that the Plan constitutes an employee pension benefit plan within the
meaning of Section 3(2) of ERISA which is not so exempt.

     15.04. Right to Accelerate. The Board of Directors in its sole discretion
may accelerate all vested benefits upon termination of the Plan, and pay such
benefits in a single, actuarially equivalent lump-sum.

                                 MISCELLANEOUS

     16.01. Prohibition Against Alienation.  Except as otherwise provided in
the Plan, no right or benefit under the Plan shall be subject in any manner to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or
charge, and any attempt to so anticipate, alienate, sell, transfer, assign,
pledge, encumber, or charge the same shall be void.  No such right or benefit
shall be liable for or subject to the debts, contracts, liabilities,
engagements, or torts of the person entitled to such right or benefit.

     16.02. Savings Clause. If any provision of this instrument shall be
finally held by a court of competent jurisdiction to be invalid or
unenforceable, the remaining provisions hereof shall continue to be fully
effective.

     16.03. Payment of Benefit of Incompetent.  In the event the Committee
finds that a Participant, former Participant, or Beneficiary is unable to care
for his affairs because of his minority, illness, accident, or other reason,
any benefits payable hereunder may, unless other claim has been made therefor
by a duly appointed guardian, committee or other legal representative, be paid
to a spouse, child, parent, or other blood relative or dependent or to any
person found by the Committee to have incurred expenses for the support and
maintenance of such Participant, former Participant, or Beneficiary; and any
such payments so made shall be a complete discharge of all liability therefor.

manner including but not limited to such spouse's will, nor shall such interest
pass under the laws of intestate succession.

or reorganization of the Company, the obligations of the Company under this
Plan shall continue and be binding upon the Company and its successors.

     16.06. Compliance With Rule 16b-3.  It is intended that the Plan be
applied and administered in compliance with Rule 16b-3 under the Securities and
Exchange Act of 1934.  If any provision of the Plan would be in violation of
Rule 16b-3 if applied as written, such provision shall not have effect as
written and shall be given effect so as to comply with Rule 16b-3, as
determined by the Board of Directors.

     16.07. Securities Law Restrictions.  The Company may impose such other
restrictions on any shares of Company common stock granted pursuant to this
Plan as it may deem advisable including, but not limited to, restrictions
intended to achieve compliance with the Securities Act of 1933, as amended,
with the Securities and Exchange Act of 1934, as amended, with the requirements
of any stock exchange upon which the Company common stock is then listed, and
with any Blue Sky or state securities laws applicable to such Company common
stock.

      legal fees, costs and expenses incurred by such claimant in seeking a
      judicial resolution of his or her claim, including reasonable fees, costs
      and expenses relating to appeals; provided, however, that the Company
      shall not be obligated to advance to the claimant any amounts under this
      Section   17.04(b) unless and
        
                                       19

                              EMPLOYMENT AGREEMENT

     AGREEMENT by and between MCN Energy Group Inc., a Michigan corporation
(the "Company") and ____________(the "Executive"), dated as of the ____ day of
___________, 19__.

     The Board of Directors of the Company (the "Board"), has determined that
it is in the best interests of the Company and its shareholders to assure that
the Company will have the continued dedication of the Executive,
notwithstanding the possibility, threat or occurrence of a Change of Control
(as defined in Section 2) of the Company.  The Board believes it is imperative
to diminish the inevitable distraction of the Executive by virtue of the
personal uncertainties and risks created by a pending or threatened Change of
Control and to encourage the Executive's full attention and dedication to the
Company currently and in the event of any threatened or pending Change of
Control, and to provide the Executive with compensation and benefits
arrangements upon a Change of Control which ensure that the compensation and
benefits expectations of the Executive will be satisfied and which are
competitive with those of other corporations.  Therefore, in order to
accomplish these objectives, the Board has caused the Company to enter into
this Agreement.

     NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

     1. Certain Definitions. (a) The "Effective Date" shall mean the first date
during the Change of Control Period (as defined in Section 1(b)) on which a
Change of Control occurs.  Anything in this Agreement to the contrary
notwithstanding, if a Change of Control occurs and if the Executive's
employment with the Company is terminated prior to the date on which the Change
of Control occurs, and if it is reasonably demonstrated by the Executive that
such termination of employment (i) was at the request of a third party who has
taken steps reasonably calculated to effect the Change of Control or (ii)
otherwise arose in connection with or anticipation of the Change of Control,
then for all purposes of this Agreement the "Effective Date" shall mean the
date immediately prior to the date of such termination of employment.

     (b) The "Change of Control Period" shall mean the period commencing on the
date hereof and ending on the third anniversary of such date; provided,
however, that commencing on the date one year after the date hereof, and on
each annual anniversary of such date (such date and each annual anniversary
thereof shall be hereinafter referred to as the "Renewal Date"), the Change of
Control Period shall be automatically extended so as to terminate three years
from such Renewal Date, unless at least 60 days prior to the Renewal Date the
Company shall give notice to the Executive that the Change of Control Period
shall not be so extended.

     2. Change of Control.  For the purpose of this Agreement, a "Change of
Control" shall mean:

     4. Terms of Employment. (a) Position and Duties.  (i) During the
Employment Period, (A) the Executive's position (including status, offices,
titles and reporting requirements), authority, duties and responsibilities
shall be at least commensurate in all material respects with the most
significant of those held, exercised and assigned at any time during the 90-day
period immediately preceding the Effective Date and (B) the Executive's
services shall be performed at the location where the Executive was employed
immediately preceding the Effective Date or any office which is the
headquarters of the Company and is less than 35 miles from such location.

     (ii) During the Employment Period, and excluding any periods of vacation
and sick leave to which the Executive is entitled, the Executive agrees to
devote reasonable attention and time during normal business hours to the
business and affairs of the Company and, to the extent necessary to discharge
the responsibilities assigned to the Executive hereunder, to use the
Executive's reasonable best efforts to perform faithfully and efficiently such
responsibilities.  During the Employment Period it shall not be a violation of
this Agreement for the Executive to (A) serve on corporate, civic or charitable
boards or committees, (B) deliver lectures, fulfill speaking engagements or
teach at educational institutions and (C) manage personal investments, so long
as such activities do not significantly interfere with the performance of the
Executive's responsibilities as an employee of the Company in accordance with
this Agreement.  It is expressly understood and agreed that to the extent that
any such activities have been conducted by the Executive prior to the Effective
Date, the continued conduct of such activities (or the conduct of activities
similar in nature and scope thereto) subsequent to the Effective Date shall not
thereafter be deemed to interfere with the performance of the Executive's
responsibilities to the Company.

     (b) Compensation. (i) Base Salary.  During the Employment Period, the
Executive shall receive an annual base salary ("Annual Base Salary"), which
shall be paid no less frequently than on a monthly basis, at least equal to
twelve times the highest monthly base salary paid or payable to the Executive
by the Company and its affiliated companies in respect of the twelve-month
period immediately preceding the month in which the Effective Date occurs.
During the Employment Period, the Annual Base Salary shall be reviewed at least
annually and shall be increased at any time and from time to time as shall be
substantially consistent with increases in base salary generally awarded in the
ordinary course of business to other peer executives of the Company and its
affiliated companies.  Any increase in Annual Base Salary shall not serve to
limit or reduce any other obligation to the Executive under this Agreement.
Annual Base Salary shall not be reduced after any such increase and the term
Annual Base Salary as utilized in this Agreement shall refer to Annual Base
Salary as so increased.  As used in this Agreement, the term "affiliated
companies" shall include any company controlled by, controlling or under common
control with the Company.

     (ii) Annual Bonus.  In addition to Annual Base Salary, the Executive shall
be awarded, for each fiscal year ending during the Employment Period, an annual
bonus

(the "Annual Bonus") in cash at least equal to the average annualized (for any
fiscal year consisting of less than twelve full months or with respect to which
the Executive has been employed by the Company for less than twelve full
months) bonus paid or payable, including by reason of any deferral, to the
Executive by the Company and its affiliated companies in respect of the three
fiscal years immediately preceding the fiscal year in which the Effective Date
occurs (the "Recent Average Bonus").  Each such Annual Bonus shall be paid no
later than the end of the third month of the fiscal year next following the
fiscal year for which the Annual Bonus is awarded, unless the Executive shall
elect to defer the receipt of such Annual Bonus.

     (iii) Incentive, Sayings and Retirement Plans.  During the Employment
Period, the Executive shall be entitled to participate in all incentive,
savings and retirement plans, practices, policies and programs applicable
generally to other peer executives of the Company and its affiliated companies,
but in no event shall such plans, practices, policies and programs provide the
Executive with incentive opportunities (measured with respect to both regular
and special incentive opportunities, to the extent, if any, that such
distinction is applicable), savings opportunities and retirement benefit
opportunities, in each case, less favorable, in the aggregate, than the most
favorable of those provided by the Company and its affiliated companies for the
Executive under such plans, practices, policies and programs as in effect at
any time during the 90-day period immediately preceding the Effective Date or
if more favorable to the Executive, those provided generally at any time after
the Effective Date to other peer executives of the Company and its affiliated
companies.

     (iv) Welfare Benefit Plans.  During the Employment Period, the Executive
and/or the Executive's family, as the case may be, shall be eligible for
participation in and shall receive all benefits under welfare benefit plans,
practices, policies and programs provided by the Company and its affiliated
companies (including, without limitation, medical, prescription, dental,
disability, salary continuance, employee life, group life, accidental death and
travel accident insurance plans and programs) to the extent applicable
generally to other peer executives of the Company and its affiliated companies,
but in no event shall such plans, practices, policies and programs provide the
Executive with benefits which are less favorable, in the aggregate, than the
most favorable of such plans, practices, policies and programs in effect for
the Executive at any time during the 90-day period immediately preceding the
Effective Date or, if more favorable to the Executive, those provided generally
at any time after the Effective Date to other peer executives of the Company
and its affiliated companies.

     (v) Expenses.  During the Employment Period, the Executive shall be
entitled to receive prompt reimbursement for all reasonable employment expenses
incurred by the Executive in accordance with the most favorable policies,
practices and procedures of the Company and its affiliated companies in effect
for the Executive at any time during the 90-day period immediately preceding
the Effective Date or, if more favorable to the Executive, as in effect
generally at any time thereafter with respect to other peer executives of the
Company and its affiliated companies.

     (vi) Fringe Benefits.  During the Employment Period, the Executive shall
be entitled to fringe benefits in accordance with the most favorable plans,
practices, programs and policies of the Company and its affiliated companies in
effect for the Executive at any time during the 90-day period immediately
preceding the Effective Date or, if more favorable to the Executive, as in
effect generally at any time thereafter with respect to other peer executives
of the Company and its affiliated companies.

     (vii) Office and Support Staff.  During the Employment Period, the
Executive shall be entitled to an office or offices of a size and with
furnishings and other appointments, and to exclusive personal secretarial and
other assistance, at least equal to the most favorable of the foregoing
provided to the Executive by the Company and its affiliated companies at any
time during the 90-day period immediately preceding the Effective Date or, if
more favorable to the Executive, as provided generally at any time thereafter
with respect to other peer executives of the Company and its affiliated
companies.

     (viii) Vacation. During the Employment Period, the Executive shall be
entitled to paid vacation in accordance with the most favorable plans,
policies, programs and practices of the Company and its affiliated companies as
in effect for the Executive at any time during the 90-day period immediately
preceding the Effective Date or, if more favorable to the Executive, as in
effect generally at any time thereafter with respect to other peer executives
of the Company and its affiliated companies.

     5. Termination of Employment. (a) Death or Disability.  The Executive's
employment shall terminate automatically upon the Executive's death during the
Employment Period.  If the Company determines in good faith that the Disability
of the Executive has occurred during the Employment Period (pursuant to the
definition of Disability sat forth below), it may give to the Executive written
notice in accordance with Section 12(b) of its intention to terminate the
Executive's employment.  In such event, the Executive's employment with the
Company shall terminate effective on the 30th day after receipt of such notice
by the Executive (the "Disability Effective Date"), provided that, within the
30 days after such receipt, the Executive shall not have returned to full-time
performance of the Executive's duties.  For purposes of this Agreement,
"Disability" shall mean the absence of the Executive from the Executive's
duties with the Company on a full-time basis for 180 consecutive business days
as a result of incapacity due to mental or physical illness which is determined
to be total and permanent by a physician selected by the Company or its
insurers and acceptable to the Executive or the Executive's legal
representative (such agreement as to acceptability not to be withhold
unreasonably).

     (b) Cause.  The Company may terminate the Executive's employment during
the Employment Period for Cause.  For purposes of this Agreement, "Cause" shall
mean (i) repeated violations by the Executive of the Executive's obligations
under Section 4(a) (other than as a result of incapacity due to physical or
mental illness) which are demonstrably willful and deliberate on the
Executive's part, which are committed in bad faith
