                    NORTH COAST ENERGY, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                   (Unaudited)


Note 1.  Summary of Accounting Policies

         A.  General

         The consolidated financial statements included herein, have been
         prepared by North Coast Energy, Inc. without audit. In the opinion of
         management, all adjustments (which include only normal recurring
         adjustments) necessary to present fairly the financial position have
         been made.

         Information and footnote disclosures normally included in financial
         statements prepared in accordance with generally accepted accounting
         principles have been condensed or omitted. It is suggested that these
         financial statements be read in conjunction with the financial
         statements and notes thereto which are incorporated in the Company's
         Annual Report on Form 10-K for the fiscal year ended March 31, 1999.

         The results of the operations for the interim periods may not
         necessarily be indicative of the results to be expected for the full
         year. In addition, the preparation of these financial statements in
         conformity with generally accepted accounting principles requires
         management to make estimates and assumptions that effect the reported
         amounts of assets and liabilities at the date of the consolidated
         financial statements and reported amounts of revenues and expenses
         during the reporting period. Actual results could differ from those
         estimates.

         B.  Principles of Consolidation

         The consolidated financial statements include the accounts of North
         Coast Energy, Inc. and its wholly owned subsidiaries (the Company),
         North Coast Operating Company (NCOC), and NCE Securities, Inc. (NCE
         Securities). In addition, the Company's investments in oil and gas
         drilling partnerships, which are accounted for under the proportional
         consolidation method, are reflected in the accompanying financial
         statements. The Company's ownership of revenues in these drilling

Note 2.  Long-Term Debt (Continued)

        On February 9, 1998, the Company entered into an agreement with ING (US)
        Capital LLC (successor in interest to ING (US) Capital Corporation)("ING
        Capital") to replace the $20,000,000 revolving credit facility with its
        previous lender. On May 29, 1998, the Company entered into an amended
        Credit Agreement with its lender increasing the Credit Facility from
        $20,000,000 to $25,000,000. The Agreement provides for a borrowing base
        which is determined semi-annually by the lender based upon the Company's
        financial position, oil and gas reserves, as well as outstanding letters
        of credit ($150,000 at June 30, 1999), as defined. At June 30, 1999, the
        Company's borrowing base was $25,000,000 subject to reduction for the
        outstanding letters of credit. Available borrowings under the facility
        at June 30, 1999 were $2,022,365 and may subsequently change based upon
        the semiannual reserve study and borrowing base determination.

        In June 1999, the Company and ING Capital entered into an amended credit
        agreement that extended the commitment period until and including July
        2, 2000. At the termination of the commitment period, borrowings on the
        note are due and payable in 20 equal quarterly installments beginning on
        September 30, 2000. ING Capital has indicated to the company that
        sometime in the future it will discontinue lending to the oil and gas
        industry. The Company is currently in the process of reviewing its
        options and financing needs with several prospective lenders.

        Amounts outstanding under the reducing revolving line of credit bear
        interest at the lending bank's prime rate plus .75% or LIBOR plus 2.50%,
        or approximately 7.65% and 8.25% at June 30, 1999 and June 30, 1998,
        respectively. The agreement requires the Company to pay a commitment fee
        of .5% on the unused amount of available borrowings. The agreement
        contains certain restrictive covenants, including working capital,
        current ratio, tangible net worth, and EBITDA calculations, as defined.
        The Company was in compliance with all covenants and restrictions at
        June 30, 1999.

        The revolving credit facility and the notes are collateralized by
        substantially all of the Company's assets including receivables,
        inventory, equipment and a first mortgage on certain of the Company's
        interests in oil and gas wells and reserves.

Note 3.  Billings in Excess of Costs on Uncompleted Contracts

        At June 30 and March 31, 1999, all drilling contracts were completed.

Note 4.  Commitment and Contingencies

        The Company and a bank have issued standby letters of credit
        which provide a guaranteed total amount of $150,000 in lieu of coverage
        provided by insurance for road bond deposits against damage.

        At June 30, 1999, the Company has committed to fund certain costs of the
        North Coast Energy Appalachian Drilling Programs estimated to be
        approximately $84,000 for tangible well equipment and pipeline
        construction.

        On April 30, 1999, Charles M. Lombardy, Jr., the Chief Executive Officer
        of the Company, was paid $370,000 in lieu of continuing his employment
        contract by signing a separation agreement with the Company.
        Additionally, Lombardy received a ten-year warrant to purchase, at $5.00
        per share, 60,000 shares of the Company's common stock. The Company
        escrowed approximately $800,000 for the purchase of the former Chief
        Executive Officer's common shares. The escrowed funds have been
        reflected as a cash and cash equivalent item on the accompanying
        Consolidated Balance Sheets. The Company is obligated to purchase the

         these shares, it will directly reduce the amount of common shares Nuon
         would be required to purchase under the Nuon Agreement.

Note 5.  Preferred Dividends

         On June 30, 1999, the Company paid a dividend of $58,216 on the
         cumulative convertible Series B Preferred Stock. On June 30, 1998, the
         Company paid a dividend of $26,826 on the cumulative convertible Series
         B Preferred Stock. For purposes of computing earnings per share for the
         three months ended June 30, 1998, dividends paid and in arrears on the
         cumulative convertible Series B Preferred Stock were $67,066.
         Cumulative dividends in arrears on the cumulative convertible Series B
         Preferred Stock are $326,010 at June 30, 1999.

Note 6.  Sale of Common Stock

         On September 29, 1998 the Company sold 1,149,425 shares of its Common
         Stock for $5 million to Nuon International bv, a limited liability
         company organized under the laws of the Netherlands ("Nuon"), pursuant
         to the terms of a stock purchase agreement ("Agreement") by and between
         the Company and Nuon dated August 1, 1997. Pursuant to the terms of the
         Agreement and subject to the satisfaction of certain conditions,
         including the development of a plan of complementary business, Nuon may
         purchase an additional 1,149,425 shares of Common Stock by
         September 30, 1999. Be exercising their option to purchase additional
         shares by September 30, 1998, Nuon's stock ownership increased to 51%
         of the Company's outstanding Common Stock. Nuon also exercised the
         right to appoint two directors at the Company's December 1998 Annual
         Meeting.

         A portion of the proceeds from the sale of Common Stock was utilized to
         reduce the amount outstanding under the Company's Credit Facility with
         the remaining proceeds being used for working capital purposes.

Note 7.  Reverse Stock Split

         On March 17, 1999, the Company's Board of Directors authorized a
         1-for-5 reverse split of its common stock effective June 7, 1999 for
         stockholders of record at the close of business on May 12, 1999. The
         par value of the common stock was not changed. All share and per-share
         amounts in the accompanying consolidated financial statements have been
         restated to give retroactive effect to the reverse stock split.

         The following discussion and analysis reviews the results of operations
and the financial condition for the Company for the three months ended June 30,
1999 and 1998. The review should be read in conjunction with the financial
information presented elsewhere herein.

COMPARISON OF THREE MONTHS ENDED JUNE 30, 1999 TO THREE MONTHS ENDED JUNE 30,
1998.

REVENUES

          Oil and gas production revenues decreased $53,046 (3%) to $1,511,866
for the three months ended June 30, 1999 compared to $1,564,912 for the prior
corresponding period. This decrease in oil and gas revenue was due to a decrease
in North Coast's production of 15,390 Mcfe (MCF equivalents) to 600,404 Mcfe for
the three months ended June 30, 1999 compared to 615,794 for the three months
ended June 30, 1998. The Company received an average price of $13.54 and $12.58
per barrel of oil for the three months ended June 30, 1999 and 1998,



                                       11

respectively, and $2.54 and $2.55 per Mcf for natural gas for the three months
ended June 30, 1999 and 1998, respectively.

         Drilling revenues for the period were $326,958 for the three months
ended June 30, 1998 with no drilling revenues recognized for the three months
ended June 30, 1999. Drilling revenues were recognized on 2 wells for the three
months ended June 30, 1998 which were in process from fiscal 1998 while North
Coast completed all contracted wells in fiscal 1999. North Coast anticipates
drilling additional wells in conjunction with its drilling program to be formed
prior to the end of the calendar year. North Coast raised $3,515,000 for its
fiscal 1999 Drilling Program and $2,718,000 for its fiscal 1998 Drilling
Programs.

         For the three months ended June 30, 1999, well operating,
transportation and other revenues increased $341,512 (85%) to $745,568 compared
to $404,056 for the three months ended June 30, 1998. This increase was
primarily due to increased revenues of $239,957 from unaffiliated third party
gas sales and $94,261 from oilfield services.

EXPENSES

         Drilling costs for the three months ended June 30, 1999 compared to the
three months ended June 30, 1998 decreased $290,792 (74%). This decrease between
comparable periods was due to the fewer number of wells recognized in drilling
revenue during the three months ended June 30, 1999 compared to the three months
ended June 30, 1998 as discussed with drilling revenues above. The Company
allocates overhead to this activity although it is anticipated that wells will
not be contracted, drilled and completed until the fourth quarter.

         Oil and gas operations increased $312,525 (126%) to $561,395 for the
three months ended June 30, 1999 compared to $248,870 for the three months ended
June 30, 1998. This increase was primarily due to increased costs of $68,611
associated with utilization of oilfield equipment and $236,898 in gas purchases
related to unaffiliated third party gas sales.

         General and administrative expenses increased $359,849 (81%) to
$803,975 for the three months ended June 30, 1999 from $444,126 for the three
months ended June 30, 1998 primarily due to payments made to the former chief
executive officer who resigned from North Coast on April 30, 1999. Under a
separation agreement, this executive was paid approximately $370,000 instead of
his existing employment contract with additional costs incurred of $26,000
associated with legal and other expenses.

         The net loss for the three months ended June 30, 1999 increased to
$560,859 from $96,498 for the three months ended June 30, 1998. The Company's
net loss attributable to common stock was $619,075 for the three months ended
June 30, 1999 compared to $163,564 for the three months ended June 30, 1998.
Dividends on the Company's series B cumulative preferred stock were paid in cash
for the three months ended June 30, 1999 of $58,216 and for the three months
ended June 30, 1998 dividends of $67,066 were paid or in arrears.

OTHER EVENTS

         On March 17, 1999, the Company's Board of Directors authorized a
1-for-5 reverse split of its common stock effective June 7, 1999 for
stockholders of record at the close of business on May 12, 1999. The par value
of the common stock was not changed.

INFLATION AND CHANGES IN PRICES

         While the costs of operations have been and will continue to be
affected by inflation, oil and gas prices have fluctuated during recent years
and generally have not followed the same pattern as inflation. With today's
global economy, especially in the area of oil and natural gas, management
believes that other forces of the economy and world events, such as OPEC, the
weather, economic factors, and the effects of supply of natural gas in the
United States and regionally have a more immediate effect on current pricing
than inflation. North Coast received an average price of $13.54 and $12.58 per
barrel for the three months ended June 30, 1999 and 1998, respectively, and
$2.54 and $2.55 per


                                       12

<PAGE>   14


Mcf for natural gas for the three months ended June 30, 1999 and 1998,
respectively. On average, Appalachian natural gas price indices decreased
$0.05/Mcf during this same period from $2.36 to $2.31 per Mcf. North Coast's
stable gas prices can be attributed to continuing its strategy of increasing
commercial and industrial end-users to its portfolio of customers. This strategy
allows North Coast the greatest opportunity to exceed the average regional
prices, while minimizing the effects of a negative fluctuation. The
industry-wide weakness of natural gas prices can be attributed to the effects of
a relatively mild winter, which lessened demand for natural gas. Although it was
anticipated that there could be a decline in gas prices during the summer
months, the demand for gas by storage facilities, the above normal summer
temperatures, and decreased drilling rig counts, have thus far kept natural gas
prices above last summer's. Other variables potentially effecting gas prices are
increased competition from Canadian gas, effects of gas storage and FERC Order
636. FERC Order 636 may have contributed to the lower spot market prices by
mandating an unbundling of pipeline service and allowing open access to a
variety of geographical markets. Management cannot predict what long-term
effects FERC Order 636 will have on either spot market prices or longer term gas
contracts.

         Currently, North Coast sells natural gas under both fixed price
contracts and on the spot market. The spot market price North Coast receives for
gas production is related to several variables, including the weather and the
effects of gas storage. North Coast anticipates that spot market prices will
continue to fluctuate in response to various factors primarily weather and
market conditions.

         In an effort to position itself to take advantage of future increases
in demand for natural gas, North Coast continues to construct new pipeline
systems in the Appalachian Basin and to contract with other pipeline systems in
the region to transport natural gas production from its wells.

LIQUIDITY AND CAPITAL RESOURCES

         The Company's working capital was $3,693,000 at June 30, 1999 compared
to $2,399,000 at March 31, 1999. The increase of $1,294,000 in working capital
at June 30, 1999 reflects borrowings on the credit facility to fund
approximately $800,000 to an escrow account for the possible purchase of North
Coast's common stock from the former chief executive officer and to fund reduced
accounts payable and accrued expenses. As of June 30, 1999, the Company had
$22,827,635 outstanding under its Credit Facility.

         The following table summarizes the Company's Statements of Cash Flows
for the three months ended June 30, 1999 and 1998:

</TABLE>

      Note:  All items in the previous table are calculated as a percentage of
             total cash sources. Total cash sources include the following items
             if positive: cash flow from operations before working capital
             changes, changes in working capital, net cash provided by investing
             activities and net cash provided by financing activities, plus any
             decrease in cash and cash equivalents.

         As the above table indicates, the Company's cash used by operating
activities decreased to $543,000 for the three months ended June 30, 1999 from
$1,238,000 for the three months ended June 30, 1998. This decrease reflects the
changes in net income, accounts receivable and billing in excess of costs on
uncompleted contracts for the three months ended June 30, 1999 compared to
relatively smaller change in accounts payable for the three months ended June
30, 1998.

         Net cash used for investing activities decreased to $665,000 for the
three months ended June 30, 1999 from $16,326,000 for the three months ended
June 30, 1998. The decrease was primarily due to the Kelt acquisition which was
completed during the quarter ended June 30, 1998. North Coast has funded its
obligation to its fiscal 1999 drilling program and development activities
associated with completing wells acquired from Kelt and the development of
proved undeveloped reserves.

         Net cash from financing activities decreased to $2,012,000 for the
three months ended June 30, 1999 from $17,288,000 for the three months ended
June 30, 1998. This decrease primarily reflects the Company's borrowings under
its credit facility to finance the Kelt acquisition.

         On February 9, 1998, North Coast entered into an agreement with ING
(U.S.) Capital Corporation to replace the $20.0 million revolving credit
facility with its previous lender. North Coast's amended credit facility, dated
May 29, 1998, expanded North Coast's $20.0 million revolving credit facility
with ING to a $25.0 million revolving credit facility. The credit agreement also
provides for a borrowing base which is determined semi-annually by the lender
based upon North Coast's financial position, oil and gas reserves, as well as
outstanding letters of credit ($150,000 at June 30, 1999). The credit agreement
requires payment of an agent fee of 0.75% on amounts available and a 0.50%
commitment fee on amounts not borrowed up to the available credit line. At June
30, 1999, North Coast's borrowing base was $25.0 million subject to reduction
for the outstanding letters of credit. Available borrowings under the facility
at June 30, 1999 were $2,022,365 and may change based upon the semi-annual
reserve study and borrowing base determination. (See note 5 to North Coast's
March 31, 1999 financial statements relating to long-term debt.) The credit
facility provides that the payment of dividends with respect to the common stock
is prohibited. As of June 30, 1999, North Coast had $22,827,635 outstanding
under the credit facility, and was in compliance with its loan covenants.
Amounts borrowed under the credit facility bear interest at the prime rate of
the lending bank plus 0.75% or LIBOR plus 2.50%. The revolving line of credit is
reviewed semi-annually and may be extended by an amendment to the current
facility or converted to a term loan on July 2, 2000.

         The lender has performed its September 30, 1998 semi-annual borrowing
base review and has provided a third amendment to the credit facility which
continues the facility without payment of principal until September 30, 2000.
The lender has indicated that, in the future, it intends to discontinue lending
in the oil and gas business in the United States and has requested that North
Coast find another lender. North Coast is currently reviewing options with
several lenders that are interested in providing at least a $25 million credit
facility.


                                       14

<PAGE>   16



         The amounts borrowed under its reducing revolving line of credit are
secured by North Coast's receivables, inventory, equipment and a first mortgage
on North Coast's interests in oil and gas wells and reserves. The mortgage notes
are secured by land and buildings.

         In addition, at June 30, 1999, North Coast had approximately $44,290
outstanding under a mortgage note payable for its facility in Youngstown. The
mortgage note bears interest at the rate of 8% and requires North Coast to make
monthly payments of approximately $1,019 through July 2003. North Coast entered
into a mortgage note for its headquarters on May 13, 1996 for $540,000 with a
15-year term and an interest rate of 8.58%. The mortgage note may be
renegotiated every five years. The amount outstanding under the mortgage note
at June 30, 1999 was $487,673.

         On September 29, 1998 North Coast sold an additional 1,149,425 shares
of its common stock for $5.0 million to Nuon, pursuant to the terms of the 1997
purchase and sale agreement between North Coast and Nuon dated August 1, 1997.
By exercising its option to purchase additional shares by September 30, 1998,
Nuon's stock ownership increased to 51% of the outstanding common stock and Nuon
gained the ability to appoint additional directors at North Coast's next annual
meeting. North Coast also issued 26,800 warrants representing the right of the
holder to purchase one share of common stock for $4.375 per share in connection
with the sale of common stock to Nuon. Pursuant to the terms of the agreement
and subject to the satisfaction of certain conditions, Nuon may purchase an
additional 1,149,426 shares of common stock by September 30, 1999. North Coast
is also obligated to issue 26,800 warrants when and if Nuon purchases an
additional 1,149,426 shares with 13,400 of the potential warrants due to Mr.
Siegel and 13,400 of the potential warrants due to Mr. Berns. The additional
warrants represent the right to purchase one share of common stock for $4.375
per share.

         On April 30, 1999, the chief executive officer resigned from North
Coast. Under a separation agreement, he was paid $370,000 instead of continuing
his employment contract and for non-competition. Additionally, he received a
ten-year warrant to purchase, at $5.00 per share, 60,000 shares of the Company's
common stock. Also, North Coast could be obligated to purchase his common stock
for $4.375 per share by October 10, 1999. North Coast has escrowed approximately
$800,000 in accordance with the separation agreement to allow it to purchase his
shares. North Coast would not be obligated to purchase the former executive's
shares of common stock if Nuon elects to purchase his shares prior to September
30, 1999 in accordance with the separation agreement. Upon Nuon's purchase of
the former executive's shares North Coast would be entitled to the escrowed
funds. However, Nuon would have the right to reduce its option under the 1997
purchase and sale agreement to the extent to which it purchases the former
executive's shares. Nuon is not obligated to exercise its option to acquire
1,149,426 shares nor is it obligated to acquire the former chief executive
officer's shares.

         North Coast continues to review potential acquisitions in the oil and
gas industry and mid to downstream energy areas, in additional to its drilling
and development activities. North Coast also anticipates continuing its
corporate drilling and development program, anticipates investing approximately
$300,000 in the drilling of five development wells in the next quarter and
anticipates drilling wells in conjunction with its drilling programs. North
Coast will continue to need financing to complete the aforementioned activities.
Management believes financing through equity provided from Nuon, funds raised in
drilling programs and the Company's existing borrowing base with a different
lender will be sufficient to fund North Coast's obligations, operations and debt
service requirements for the next year.

         If Nuon does not purchase the additional shares related to the 1997
sales and purchase agreement and elects not to purchase the former chief
executive's common shares, North Coast would be forced to change its strategy of
growth. North Coast would reduce its projects accordingly in an effort to
conserve cash. Also, if suitable financing on acceptable terms could not be
negotiated prior to September 30, 2000 with another lender North Coast would be
required to make quarterly principle payments currently in excess of $1 million.
Without equity or other financing North Coast may have to cut costs, reduce
staff or sell assets to meet this ongoing principal payment obligation.
Management believes, however, that financing at some acceptable level would be
available before September 30, 2000.

YEAR 2000 READINESS DISCLOSURE

         North Coast has developed an action plan and identified the resources
required to convert its computer systems and software applications to achieve
Year 2000 compliance with no anticipated effect on its customers or disruption
of its



                                       15


<PAGE>   17



business operations. North Coast has already implemented the first three phases
of its four-phase action plan. In phase one, North Coast assessed its
information technology and non-IT systems. The term "computer equipment and
software" includes systems that are commonly thought of as IT systems, including
accounting, data processing, telephone, scanning equipment and other
miscellaneous systems. Those items not considered IT systems include alarms, fax
machines and monitors for field operations. Both IT and non-IT systems may
contain embedded technology which complicates Year 2000 identification and
assessment efforts. In phase two North Coast included the upgrade of its PC
equipment and software.

         In phase three, North Coast tested existing systems and determined
whether those systems suspect to Year 2000 compliance problems should be
replaced. In phase three, North Coast replaced systems and software because of
the Year 2000 issue and because the Kelt acquisition necessitated newer and more
compatible systems. North Coast estimates that the cost to complete phases one,
two and three, which primarily includes the purchase of software and hardware
upgrades under normal maintenance agreements with third party vendors, will be
approximately $60,000. To date, North Coast has incurred approximately 83.0% of
these anticipated costs.

         Phase four of North Coast's action plan involves the implementation of
North Coast's Year 2000 compliant software and the reevaluation of all of North
Coast's material systems. North Coast may engage independent consultants to
assist in completing phase four. The additional cost of these independent
consultants has not been determined and has not yet been included in North
Coast's Year 2000 compliance cost estimates.

         In addition, North Coast has discussed Year 2000 compliance issues with
its vendors and customers. Although North Coast has no reason to believe that
its vendors and customers will not be Year 2000 compliant, North Coast is unable
to determine the extent to which Year 2000 issues will effect its vendors and
customers. North Coast continues to discuss procedures necessary to address this
issue with its vendors and customers.

         North Coast presently does not plan to incur significant operational
problems due to the Year 2000 issue. However, there can be no assurance that the
Year 2000 issue will not materially impact North Coast's financial condition or
results of operations, or adversely effect its relationship with customers,
vendors and others. Additionally, there can be no assurance that the Year 2000
issues of other entities will not have a material impact on North Coast's
systems or results of operations. North Coast plans to establish a contingency
plan for dealing with the most reasonably likely worst-case scenario. To date,
this scenario has not been clearly identified. North Coast plans to complete
this analysis and contingency planning by the second quarter of fiscal 2000.

ACCOUNTING STANDARDS

    In June 1998, SFAS 133, "Accounting for Derivative Instruments and Hedging
Activities," was issued. SFAS 133 establishes accounting and reporting standards
for derivative instruments and hedging activities. In June 1999, the FASB issued
SFAS No. 137, "Accounting for Derivative Instruments and Hedging Activities -
Deferral of the Effective Date of FASB Statement No. 133 - an Amendment of FASB
Statement No. 133." SFAS No. 137 delayed the original implementation date of
SFAS No. 133 until June 15, 2000. The effect of the adoption or anticipated
adoption of the above standards is expected to have no material effect on North
Coast's financial statements.
