                 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1998
                                   (UNAUDITED)



1. ACCOUNTING PRINCIPLES

The accompanying unaudited consolidated financial statements of Chesapeake
Energy Corporation and subsidiaries (the "Company") have been prepared in
accordance with the instructions to Form 10-Q as prescribed by the Securities
and Exchange Commission. All material adjustments (consisting solely of normal
recurring adjustments) which, in the opinion of management, are necessary for a
fair presentation of the results for the interim periods have been reflected.
The results for the three and nine months ended September 30, 1998 are not
necessarily indicative of the results to be expected for the full fiscal year.

The Company changed its fiscal year end from June 30 to December 31 for the
period ended December 31, 1997. This Form 10-Q relates to the three and nine
months ended September 30, 1998 (the "Current Quarter" and "Current Period",
respectively) and September 30, 1997 (the "Prior Quarter" and "Prior Period",
respectively).

2. RECENT EVENTS

On July 7, 1998 the Company's Board of Directors authorized management to
explore strategic alternatives to enhance shareholder value, including a
possible sale or merger of the Company, based upon the Board's opinion that the
market was substantially undervaluing the Company's assets and exploration
potential. Also on July 7, 1998 Chesapeake's Board of Directors unanimously
adopted a shareholder rights plan designed to deter coercive takeover tactics
and to prevent a change of control from occurring without all shareholders
receiving a fair price.

Pursuant to the decision to explore various alternatives, the Company engaged
Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ") to advise the
Company. The Company and DLJ are presently evaluating various alternatives,
including the potential sale or merger of the Company, sale of certain assets,
or alternative financial strategies. This process is underway and is expected to
be concluded within the next few months.

On November 2, 1998 the Company announced it had entered into an agreement to
tender its 19.9% stake in Pan East Petroleum Corp. ("Pan East") to Poco
Petroleums Ltd. and agreed to a property exchange with Pan East. Subject to the
successful completion by Poco of its tender offer, the Company anticipates
receiving approximately $26 million in cash and increasing its net reserves by
four bcfe. As of September 30, 1998, the Company's net investment in the common
stock of Pan East of $21.3 million has been accounted for using the equity
method and is included in Other Assets in the accompanying Consolidated Balance
Sheets.

3. LEGAL PROCEEDINGS

The Company and certain of its officers and directors are defendants in a
consolidated class action suit alleging violations of the Securities Exchange
Act of 1934. The plaintiffs assert that the defendants made material
misrepresentations and failed to disclose material facts about the success of
the Company's exploration efforts in the Louisiana Trend. As a result, the
complaint alleges the price of the Company's common stock was artificially
inflated from January 25, 1996 until June 27, 1997, when the Company issued a
press release announcing disappointing drilling results in the Louisiana Trend
and a full-cost ceiling writedown to be reflected in its June 30, 1997 financial
statements. The plaintiffs further allege that certain of the named individual
defendants sold common stock during the class period when they knew or should
have known adverse nonpublic information. The plaintiffs seek a determination
that the suit is a proper class action and damages in an unspecified amount,
together with interest and costs of litigation, including attorneys' fees. The
Company and the individual defendants believe that these claims are without
merit, and intend to defend against them vigorously. No estimate of loss or
range of estimate of loss, if any, can be made at this time.

A purported class action alleging violations of the Securities Act of 1933 and
the Oklahoma Securities Act has been filed against the Company and others on
behalf of investors who purchased common stock of Bayard Drilling Technologies,
Inc. ("Bayard") in, or traceable to, its initial public offering in November
1997. Total proceeds of the

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                   (UNAUDITED)


offering were $254 million, of which the Company received net proceeds of $90
million as a selling shareholder. Plaintiffs allege that the Company, a major
customer of Bayard's drilling services and the owner of 30.1% of Bayard's common
stock outstanding prior to the offering, was a controlling person of Bayard.
Plaintiffs assert that the Bayard prospectus contained material omissions and
misstatements relating to (i) the Company's financial "problems" and their
impact on Bayard's operating results, (ii) increased costs associated with
Bayard's growth strategy, (iii) undisclosed pending related-party transactions
between Bayard and third parties other than the Company, (iv) Bayard's planned
use of offering proceeds and (v) Bayard's capital expenditures and liquidity.
The alleged defective disclosures are claimed to have resulted in a decline in
Bayard's share price following the public offering. Plaintiffs seek a
determination that the suit is a proper class action and damages in an
unspecified amount or rescission, together with interest and costs of
litigation, including attorneys' fees. The Company believes that the claims are
without merit and intends to defend against them vigorously. No estimate of loss
or range of estimate of loss, if any, can be made at this time.

In October 1996, Union Pacific Resources Company ("UPRC") sued the Company
alleging infringement of a patent for a drillbit steering method. Other claims
asserted by UPRC have been dismissed. UPRC's infringement claims against the
Company are based on services provided to the Company by a third party vendor
controlled by former UPRC employees. UPRC is seeking injunctive relief, damages
of an unspecified amount, including actual and enhanced damages, interest, costs
and attorneys' fees. The Company believes that it has meritorious defenses to
UPRC's allegations and that the UPRC patent is invalid. The Company has filed a
motion to construe UPRC's patent claims and other dispositive motions are
pending. No estimate of loss or range of estimate of loss, if any, can be made
at this time; however, in reports filed in the proceeding, experts for UPRC
claim that damages could be as much as $18 million while Company experts state
that the amount should not exceed $25,000, in each case based on a reasonable
royalty.

The Company is currently involved in various other routine disputes incidental
to its business operations. While it is not possible to determine the ultimate
disposition of these matters, management, after consultation with legal counsel,
is of the opinion that the final resolution of all such currently pending or
threatened litigation is not likely to have a material adverse effect on the
consolidated financial position or results of operations of the Company.

4. NET LOSS PER SHARE

In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 128, Earnings Per Share ("SFAS
128"). SFAS 128 requires presentation of "basic" and "diluted" earnings per
share, as defined, on the face of the statement of operations for all entities
with complex capital structures. SFAS 128 is effective for financial statements
issued for periods ending after December 15, 1997 and requires restatement of
all prior period earnings per share amounts. The Company has adopted SFAS 128
and has restated all prior periods presented.

SFAS 128 requires a reconciliation of the numerators and denominators of the
basic and diluted EPS computations. For the Current Quarter, the Current Period
and the Prior Period, there was no difference between actual weighted average
shares outstanding, which are used in computing basic EPS, and diluted weighted
average shares outstanding, which are used in computing diluted EPS. Options to
purchase 10.6 million and 8.5 million shares of common stock at a weighted
average exercise price of $3.88 and $5.48 were outstanding at September 30, 1998
and 1997, respectively, but were not included in the computation of diluted EPS
because the effect of these outstanding options would be antidilutive. A
reconciliation for the Prior Quarter is as follows:

5. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENT

In June 1997, the FASB issued Statement of Financial Accounting Standards No.
131 "Disclosures about Segments of an Enterprise and Related Information". This
Statement establishes standards for the way that public enterprises report
information about operating segments in annual financial statements and requires
that those enterprises report selected information about operating segments in
interim financial reports issued to shareholders. The Statement is effective for
annual financial statements for periods beginning after December 15, 1997 and
for interim financial statements issued subsequent to adoption in the annual
financial statements. The Company expects that the adoption of this standard
will not impact its results of operation or financial position, but may require
additional disclosures.

In June 1998, the FASB issued Statement of Financial Accounting Standards No.
133, Accounting for Derivative Instruments and Hedging Activities ("FAS 133").
FAS 133 is effective for all fiscal quarters of all fiscal years beginning after
June 15, 1999 (January 1, 2000 for the Company). FAS 133 requires that all
derivative instruments be recorded on the balance sheet at their fair value.
Changes in the fair value of derivatives are recorded each period in current
earnings or other comprehensive income, depending on whether a derivative is
designed as part of a hedge transaction and, if it is, the type of hedge
transaction. For fair-value hedge transactions in which the Company is hedging
changes in the fair value of an asset, liability, or firm commitment, changes in
the fair value of the derivative instrument will generally be offset in the
income statement by changes in the hedged item's fair value. For cash-flow hedge
transactions, in which the Company is hedging the variability of cash flows
related to a variable-rate asset, liability, or a forecasted transaction,
changes in the fair value of the derivative instrument will be reported in other
comprehensive income. The gains and losses on the derivative instrument that are
reported in other comprehensive income will be reclassified as earnings in the
periods in which earnings are impacted by the variability of the cash flows of
the hedged item. The ineffective portion of all hedges will be recognized in
current-period earnings.

The Company has not yet determined the impact that the adoption of FAS 133 will
have on its results of operations or its financial position.

6. ACQUISITION OF HUGOTON

In March 1998, the Company acquired Hugoton Energy Corporation ("Hugoton")
pursuant to a merger by issuing 25.8 million shares of the Company's common
stock in exchange for 100% of Hugoton's common stock. The acquisition of Hugoton
was accounted for using the purchase method as of March 1, 1998, and the results
of operations of Hugoton have been included since that date.

The following unaudited pro forma information has been prepared assuming Hugoton
had been acquired as of the beginning of the periods presented. The pro forma
information is presented for information purposes only and is not necessarily
indicative of what would have occurred if the acquisition had been made as of
those dates. In

                          PART I. FINANCIAL INFORMATION

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

RECENT EVENTS

On July 7, 1998 the Company's Board of Directors authorized management to
explore strategic alternatives to enhance shareholder value, including a
possible sale or merger of the Company, based upon the Board's opinion that the
market is substantially undervaluing the Company's assets and exploration
potential. Also on July 7, 1998 Chesapeake's Board of Directors unanimously
adopted a shareholder rights plan designed to deter coercive takeover tactics
and to prevent a change of control from occurring without all shareholders
receiving a fair price.

Pursuant to the decision to explore various alternatives, the Company engaged
Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ") to advise the
Company. The Company and DLJ are presently evaluating various alternatives,
including the potential sale or merger of the Company, sale of certain assets,
or alternative financial strategies. This process is underway and is expected to
be concluded within the next few months.

On November 2, 1998 the Company announced it entered into an agreement to tender
its 19.9% stake in Pan East Petroleum Corp. ("Pan East") to Poco Petroleums Ltd.
and agreed to a property exchange with Pan East. Subject to the successful
completion by Poco of its tender offer, the Company anticipates receiving
approximately $26 million in cash and increasing its net reserves by four
billion cubic feet equivalent of natural gas. As of September 30, 1998, the
Company's net investment in the common stock of Pan East of $21.3 million has
been accounted for using the equity method and is included in Other Assets in
the accompanying Consolidated Balance Sheets.

RESULTS OF OPERATIONS

Three Months Ended September 30, 1998 vs. September 30, 1997

General. For the three months ended September 30, 1998 (the "Current Quarter"),
the Company realized a net loss of $4.1 million, or a loss of $0.08 per common
share after deducting preferred dividends of $4.0 million. This compares to net
income of $5.5 million, or income of $0.08 per common share, for the three
months ended September 30, 1997 (the "Prior Quarter").

During the Current Quarter and Prior Quarter, the Company did not record any
impairment of its oil and gas properties. Any future impairment is subject to a
number of factors, some of which are beyond the control of the Company,
including oil and natural gas prices. Lower oil or gas prices could have a
material adverse effect on the Company's operations and financial condition and
may result in future write-downs of the Company's oil and gas properties due to
full-cost ceiling test limitations. As of September 30, 1998, the Company
estimates that the present value (SEC-PV10%) of its proved reserves, based on
prices at that time of $15.43 per bbl (NYMEX) and $2.32 per mcf (NYMEX),
adjusted for usual well-head quality and location (basis) variances, was $929
million. The Company estimates that, as of September 30, 1998, for every $0.10
per thousand cubic feet ("mcf") reduction in natural gas prices and $1.00 per
barrel of oil ("bbl") reduction in oil prices, the present value of the
Company's proved oil and gas reserves would be reduced by approximately $55
million and $22 million, respectively.


Oil and Gas Sales. During the Current Quarter, oil and gas sales increased
significantly to $70.1 million from $45.7 million, an increase of $24.4 million,
or 53%. This increase resulted from significantly higher oil and gas production
volumes, which increased from 19.2 bcfe in the Prior Quarter to 36.3 bcfe in the
Current Quarter, an increase of 17.1 bcfe, or 89%. The higher production volumes
were primarily the result of the Company's acquisitions completed during the
first four months of 1998. For the Current Quarter, the Company produced 1.6
million barrels of oil ("mmbo") and 26.8 billion cubic feet of natural gas
("bcf"), compared to 0.9 mmbo and 13.9 bcf in the Prior Quarter. Average oil
prices realized were $12.41 per barrel of oil in the Current Quarter compared 




                                       16
<PAGE>   17



to $18.48 per barrel in the Prior Quarter, a decrease of 33%. Average gas prices
realized were $1.88 per mcf in the Current Quarter compared to $2.12 per mcf in
the Prior Quarter, a decrease of 11%.

For the Current Quarter, the Company realized an average price of $1.93 per
thousand cubic feet equivalent of natural gas ("mcfe"), compared to $2.38 per
mcfe in the Prior Quarter. The Company's hedging activities resulted in
increased oil and gas revenues of $6.5 million, or $0.18 per mcfe, in the
Current Quarter, compared to increases in oil and gas revenues of $0.4 million
in the Prior Quarter.

The following table shows the Company's production by region for the Current
Quarter and the Prior Quarter:

</TABLE>


Natural gas production represented approximately 74% of the Company's total
production volume on an equivalent basis in the Current Quarter, compared to 73%
in the Prior Quarter. The Company anticipates natural gas will represent 70-80%
of anticipated 1998 and 1999 production.

Oil and Gas Marketing Sales. The Company realized $36.3 million in oil and gas
marketing sales for third parties in the Current Quarter, with corresponding oil
and gas marketing expenses of $34.7 million, for a gross profit margin of $1.6
million. This compares to sales of $26.9 million and expenses of $26.7 million,
resulting in a gross profit margin of $0.2 million in the Prior Quarter.

Interest and Other. Interest and other revenues for the Current Quarter were
$0.8 million compared to $5.9 million in the Prior Quarter. The decrease was
primarily caused by the Company maintaining lower invested cash balances
resulting in reduced interest income during the Current Quarter.

Production Expenses and Taxes. Production expenses increased to $14.2 million in
the Current Quarter, a $10.3 million increase from $3.9 million incurred in the
Prior Quarter. This significant increase was due to higher production
attributable to acquisitions and higher unit-of-production expense. On a
production unit basis, production expenses were $0.39 and $0.20 per mcfe in the
Current and Prior Quarters, respectively. Properties acquired in late 1997 and
1998 typically have higher unit-of-production expenses than the Company's
historical production base. The Company anticipates production expenses will
average $0.40 per mcfe for 1998.

Production taxes, which consist primarily of wellhead severance taxes, were $2.0
million and $1.3 million in the Current and Prior Quarters, respectively. This
increase was the result of increased production, offset by certain accounting
reclassifications. On a per unit basis, production taxes were $0.05 per mcfe in
the Current Quarter compared to $0.07 per mcfe in the Prior Quarter. The Company
anticipates incurring production taxes at the rate of $0.07 per mcfe for the
remainder of 1998 and 1999.

Oil and Gas Depreciation, Depletion and Amortization. Depreciation, depletion
and amortization of oil and gas properties ("DD&A") for the Current Quarter was
$34.1 million, compared to $28.6 million in the Prior Quarter. This increase was
caused by significantly increased production, partially offset by a decrease in
the DD&A rate per mcfe from $1.49 to $0.94 in the Prior and Current Quarters,
respectively. The Company's DD&A rate is expected to be approximately
$0.95-$1.00 per mcfe for the remainder of 1998.

Depreciation and Amortization of Other Assets. Depreciation and amortization of
other assets ("D&A") increased to $2.5 million in the Current Quarter compared
to $1.1 million in the Prior Quarter. This increase in D&A was caused by
increased investments in depreciable buildings and equipment incurred in
conjunction with the 




                                       17

<PAGE>   18




acquisitions and increased amortization of debt issuance costs as a result of
the issuance of Senior Notes in April 1998. The Company anticipates D&A expense
throughout the remainder of 1998 to remain at approximately the same level
incurred in the Current Quarter.

General and Administrative. General and administrative expenses ("G&A"), which
are net of capitalized internal payroll and non-payroll expenses, were $5.2
million in the Current Quarter compared to $2.8 million in the Prior Quarter.
This increase was primarily caused by increased employment levels resulting from
the Company's acquisitions. The Company capitalized $0.8 million of internal
costs in the Current Quarter directly related to the Company's oil and gas
exploration and development efforts, compared to $1.4 million in the Prior
Quarter. The Company anticipates that G&A costs for the remainder of 1998 will
not increase significantly and expects G&A costs to trend somewhat lower in
1999.

Interest. Interest expense increased to $18.6 million in the Current Quarter
from $8.6 million in the Prior Quarter. This increase was a result of additional
interest expense in the Current Quarter on the $500 million principal amount of
Senior Notes issued on April 22, 1998. In addition to the interest expense
reported, the Company capitalized $2.0 million of interest during the Current
Quarter compared to $2.6 million capitalized in the Prior Quarter. The Company
does not anticipate interest expense will increase significantly during the
remainder of 1998.

Provision for Income Taxes. The Company recorded no income tax expense for the
Current Quarter or the Prior Quarter. At September 30, 1998, the Company had a
net operating loss carryforward of approximately $525 million for regular
federal income taxes which will expire in future years beginning in 2007.
Management believes that it cannot be demonstrated at this time that it is more
likely than not that the deferred income tax assets, comprised primarily of the
net operating loss carryforward, will be realizable in future years, and
therefore a valuation allowance has been recorded equaling the net deferred tax
asset. The Company does not expect to record any book income tax expense or
benefit for the remainder of 1998.

Nine Months Ended September 30, 1998 vs. September 30, 1997

General. For the nine months ended September 30, 1998 (the "Current Period"),
the Company realized a net loss of $508.7 million, or a loss of $5.48 per common
share after deducting preferred dividends of $8.1 million. This compares to a
net loss of $196.3 million, or a loss of $2.79 per common share, in the nine
months ended September 30, 1997 (the "Prior Period"). The loss in the Current
Period was primarily caused by a $466 million asset writedown recorded under the
full-cost method of accounting, a $10 million impairment related to certain of
the Company's gas processing and transportation assets located in Louisiana, a
$13.3 million extraordinary loss on the early extinguishment of debt, and a
$19.4 million loss from recurring operations. The asset writedown was partially
caused by the acquisitions completed during the Current Period for consideration
in excess of the present value (10% discount) of the future net revenues of the
acquired proved reserves as of March 31, 1998 or June 30, 1998. See "-
Impairment of Oil and Gas Properties". The loss in the Prior Period was caused
by a $236 million asset write-down recorded under the full-cost method of
accounting. The asset writedown in the Prior Period was primarily caused by poor
exploration results in the Company's drilling program, particularly in the
Austin Chalk portion of the Louisiana Trend, combined with decreased oil and gas
prices, and higher drilling and equipping costs.

Oil and Gas Sales. During the Current Period, oil and gas sales increased
significantly to $196.0 million from $148.4 million, an increase of $47.6
million, or 32%. This increase resulted from significantly higher oil and gas
production volumes, which increased from 61.0 bcfe in the Prior Period to 96.5
bcfe in the Current Period, an increase of 35.5 bcfe, or 58%. The higher
production volumes were primarily the result of the Company's acquisitions
completed during the first four months of 1998. For the Current Period, the
Company produced 4.6 mmbo and 69.0 bcf, compared to 2.5 mmbo and 45.9 bcf in the
Prior Period. Average oil prices realized were $13.21 per barrel in the Current
Period compared to $19.66 per barrel in the Prior Period, a decrease of 33%.
Average gas prices realized were $1.96 per mcf in the Current Period compared to
$2.15 per mcf in the Prior Period, a decrease of 9%.

For the Current Period, the Company realized an average price of $2.03 per mcfe,
compared to $2.43 per mcfe in the Prior Period. The Company's hedging activities
resulted in increased oil and gas revenues of $10.5 million, or 




                                       18


<PAGE>   19



$0.11 per mcfe, in the Current Period, compared to increases in oil and gas
revenues of $0.1 million in the Prior Period.

</TABLE>


Natural gas production represented approximately 72% of the Company's total
production volume on an equivalent basis in the Current Period, compared to 75%
in the Prior Period.

Oil and Gas Marketing Sales. The Company realized $96.4 million in oil and gas
marketing sales for third parties in the Current Period, with corresponding oil
and gas marketing expenses of $94.7 million, resulting in a gross profit margin
of $1.7 million. This compares to sales of $73.0 million and expenses of $72.3
million with a gross profit margin of $0.7 million in the Prior Period.

Interest and Other. Interest and other revenues for the Current Period were $3.6
million compared to $14.6 million in the Prior Period. The decrease was
primarily caused by the Company maintaining lower invested cash balances
resulting in reduced interest income during the Current Period.

Production Expenses and Taxes. Production expenses increased to $36.8 million in
the Current Period, a $25.7 million increase from $11.1 million incurred in the
Prior Period, due to the significantly higher production levels and higher per
unit costs. On a production unit basis, production expenses were $0.38 and $0.18
per mcfe in the Current and Prior Periods, respectively. The primary reason for
the increase per mcfe was production from properties acquired in late 1997 and
1998, which typically have higher unit-of-production expenses than the Company's
historical production base.

Production taxes, which consist primarily of wellhead severance taxes, were $6.1
million and $3.3 million in the Current and Prior Periods, respectively. This
increase was primarily the result of increased production. On a per unit basis,
production taxes were $0.06 per mcfe in the Current Period compared to $0.05 per
mcfe in the Prior Period, the result of higher tax rates associated with
production from properties acquired in late 1997 and 1998 compared to the
Company's historical production base.

Impairment of Oil and Gas Properties. The Company utilizes the full-cost method
to account for its investments in oil and gas properties. Under this method, all
costs of acquisition, exploration and development of oil and gas reserves
(including such costs as leasehold acquisition costs, geological and geophysical
expenditures, certain capitalized internal costs, dry hole costs and tangible
and intangible development costs) are capitalized as incurred. These oil and gas
property costs, including the estimated future capital expenditures to develop
proved undeveloped reserves, are depleted and charged to operations using the
unit-of-production method based on the ratio of current production to proved oil
and gas reserves as estimated by the Company's independent engineering
consultants and Company engineers. Costs directly associated with the
acquisition and evaluation of unproved properties are excluded from the
amortization computation until it is determined whether or not proved reserves
can be assigned to the property or whether impairment has occurred. To the
extent that capitalized costs of oil and gas properties, net of accumulated
depreciation, depletion and amortization and related deferred income taxes,
exceed the discounted future net revenues of proved oil and gas properties, such
excess costs are charged to operations.

The Company incurred an impairment of oil and gas properties charge of $466
million in the Current Period ($250 million recorded during the quarter ended
March 31, 1998, and $216 million recorded during the quarter ended June 




                                       19

30, 1998), compared to an impairment charge of $236 million in the Prior Period.
The writedown in the Current Period was caused by a combination of several
factors, including the acquisitions completed by the Company during the Current
Period, which were accounted for using the purchase method. The most significant
of these acquisitions were Hugoton Energy Corporation and DLB Oil & Gas, Inc.
Higher drilling and completion costs, the evaluation of certain leasehold,
seismic and other exploration-related costs that were previously unevaluated,
together with decreases in oil and gas prices from December 31, 1997 to June 30,
1998, were the remaining contributing factors which led to the writedown in the
Current Period. The $236 million writedown incurred in the Prior Period was due
primarily to significant expenditures for acreage acquisition and drilling costs
followed by unfavorable exploration and production results in Louisiana,
together with increases in drilling and equipment costs and lower oil and gas
prices as of June 30, 1997. Future impairment charges, if any, will be dependent
upon several factors, primarily oil and gas prices in effect at the date of
determination and the results of the Company's exploration activities.

Impairment of Other Assets. In the Current Period, the Company incurred an
impairment charge of $10 million as of June 30, 1998 related to certain of the
Company's gas processing and transportation assets located in Louisiana. No such
charge was recorded in the Prior Period.

Oil and Gas Depreciation, Depletion and Amortization. DD&A for the Current
Period was $109.3 million, compared to $95.6 million in the Prior Period. This
increase was caused by significantly increased production offset by a decrease
in the DD&A rate per mcfe from $1.57 to $1.13 in the Prior and Current Periods,
respectively.

Depreciation and Amortization of Other Assets. D&A increased to $5.8 million in
the Current Period compared to $3.1 million in the Prior Period. This increase
in D&A was caused by increased investments in depreciable buildings and
equipment incurred in conjunction with acquisitions and increased amortization
of debt issuance costs as a result of the issuance of Senior Notes in April
1998.

General and Administrative. G&A, which is net of capitalized internal payroll
and non-payroll expenses, was $14.7 million in the Current Period compared to
$7.8 million in the Prior Period. This increase was primarily caused by
increased employment levels associated with the Company's acquisitions. The
Company capitalized $4.0 million of internal costs in the Current Period
directly related to the Company's oil and gas exploration and development
efforts, compared to $4.2 million in the Prior Period.

Interest. Interest expense increased to $47.9 million in the Current Period from
$20.9 million in the Prior Period. This increase was a result of additional
interest expense in the Current Period on the $500 million principal amount of
Senior Notes issued on April 22, 1998. In addition to the interest expense
reported, the Company capitalized $5.8 million of interest during the Current
Period compared to $7.9 million capitalized in the Prior Period.

Provision for Income Taxes. The Company recorded no income tax expense for the
Current Period, and recorded a $17.9 million tax benefit in the Prior Period.

Loss on Early Extinguishment of Debt. During the Current Period and Prior
Period, the Company recorded a loss on early extinguishment of debt of $13.3
million and $0.2 million, respectively. The loss in the Current Period was due
primarily to the early retirement of the Company's 10.5% Senior Notes due 2002.
The cost to acquire the $90 million aggregate principal amount 10.5% Senior
Notes of $99 million, together with the write-off of associated debt issue
costs, resulted in an extraordinary charge of $13.3 million during the Current
Period. The Company did not record any such charges in the Current Quarter or
Prior Quarter.

RISK MANAGEMENT ACTIVITIES

Periodically the Company utilizes hedging strategies to hedge the price of a
portion of its future oil and gas production. These strategies include (1) swap
arrangements that establish an index-related price above which the Company pays
the counterparty and below which the Company is paid by the counterparty, (2)
the purchase of index-related puts that provide for a "floor" price below which
the counterparty pays the Company the amount by which the price of the commodity
is below the contracted floor, (3) the sale of index-related calls that provide
for a "ceiling" price above which the Company pays the counterparty the amount
by which the price of the commodity is above the contracted ceiling, and (4)
basis protection swaps, which are arrangements that guarantee the price
differential of oil or gas from a specified delivery point or points. The
Company only enters into commodity hedging transactions related to the Company's
oil and gas production volumes or physical purchase or sale commitments of its
oil and gas marketing subsidiaries. Results from commodity hedging transactions
are reflected in oil and gas sales to the extent related to the Company's oil
and gas production. Gains or losses on crude oil and natural gas hedging
transactions are recognized as price adjustments in the months of related
production.

As of September 30, 1998, the Company had the following natural gas swap
arrangement for periods after September 1998:

           October 1998...............       4,960,000           $  2.346
</TABLE>

The swap arrangement listed above was closed but not settled as of September 30,
1998, resulting in net proceeds to the Company of $1.1 million in October 1998.
The Company has closed transactions for natural gas previously hedged for the
period April 1999 through November 1999 and locked in net proceeds of $3.2
million. Subsequent to September 30, 1998, the Company sold December 1998
natural gas call options with a strike price of $2.60 on volume of 3.1 bcf for
$0.1325 per mmbtu, and sold January 1999 natural gas call options with a strike
price of $2.70 on volume of 3.1 bcf for $0.2225 per mmbtu.

As of October 15, 1998, the Company closed transactions for oil previously
hedged from January 1999 through December 1999, resulting in a $0.9 million
reduction of revenue. The Company has closed transactions for crude oil
previously hedged for the period from September 1998 through February 1999 and
has locked in net proceeds of $0.4 million.

The Company also utilizes hedging strategies to manage fixed-interest rate
exposure. Through the use of a swap arrangement, the Company believes that it
can benefit from stable or falling interest rates and reduce its upfront
interest expense. As of September 30, 1998, the Company's interest rate swap
resulted in a $0.2 million reduction of interest expense for the period August
1998 through October 1998, which settled on November 2, 1998.

LIQUIDITY AND CAPITAL RESOURCES

In April 1998, the Company completed an offering of $230 million of 7%
Cumulative Convertible Preferred Stock and $500 million principal amount of
9.625% Senior Notes due 2005. The net proceeds of these offerings were
approximately $711 million, of which $170 million was used to retire all of the
Company's commercial bank debt, approximately $99 million was used to retire all
$90 million principal amount of the Company's 10.5% Senior Notes due 2002, $345
million was used to fund certain of the Company's acquisitions, with the balance
of the net proceeds increasing the Company's working capital.

As of September 30, 1998, the Company had a working capital deficit of
approximately $2.0 million. The Company, as the result of significantly lower
oil and gas prices and a change in the Company's strategy away from higher risk
drilling and toward a more balanced acquisition and exploitation strategy, has
continued to reduce its capital expenditure plans. The Company currently
estimates that it will expend approximately $50 million for drilling, seismic
and leasehold expenditures for the three months ended December 31, 1998 and is
currently




                                       21

<PAGE>   22




budgeting $195 million in expenditures for 1999. The capital expenditure budget
is largely discretionary, and can be adjusted by the Company based on operating
results or other factors. The Company believes it has sufficient capital
resources from anticipated cash flow from operations, planned asset sales and
unused commercial bank facilities to fund the reduced drilling program for the
remainder of 1998.

As part of its capital resources plan, the Company has undertaken to sell
various non-core assets. The Company expects to realize between $75 and $100
million of cash from these asset sales within the six months beginning October
1, 1998, inclusive of the $26 million transaction announced on November 2, 1998
between Poco Petroleums Ltd. and the Company involving Pan East common stock and
oil and gas reserves in the Helmet area of British Columbia. Other completed
asset sales combined with offers currently in hand total approximately $25
million. These asset sales are independent of the Company's strategic
alternatives evaluation process.

The Company has a $50 million secured revolving bank facility with its primary
commercial bank. As a result of its reduced capital expenditure plan, reduced
acquisition program, and the planned sale of assets, the Company believes this
size of bank facility is appropriate for the foreseeable future, although
significantly larger secured facilities could be established within the limits
of the Company's senior note indentures. The facility contains terms and
conditions similar to the bank facilities the Company has had in the past,
including collateral-based borrowing limitations. The primary purpose of the
facility is to provide standby liquidity for the Company. The Company had no
borrowings outstanding under this facility at September 30, 1998.

On May 20, 1998, the Company's Board of Directors approved the expenditure of up
to $25 million to purchase outstanding Company common stock. On July 14, 1998,
the Board increased the authorized expenditure to $30 million. As of August 25,
1998 the Company had purchased approximately 8.5 million shares of common stock
for an aggregate amount of $30.0 million pursuant to such authorization.

The Company's senior note indentures contain restrictions on the Company's
ability to make Restricted Payments (as defined), including the payment of
preferred stock dividends unless certain tests are met. The Company anticipates
that, based on expected production, pricing, and expenses for the twelve months
ending December 31, 1998, it may not be able to meet the requirements to incur
additional unsecured indebtedness, and consequently would not be able to pay
cash dividends on its 7% Cumulative Convertible Preferred Stock as of February
1, 1999. Subsequent payments will be subject to the same restrictions and are
dependent upon variables that are beyond the Company's ability to predict,
chiefly the future level of oil and gas prices. This restriction does not affect
the Company's ability to borrow under or expand its secured commercial bank
facility. If the Company fails to pay dividends for six quarterly periods, the
holders of preferred stock would be entitled to elect two additional members to
the Board.

The Company's cash provided by operating activities before changes in current
assets and liabilities decreased 17% to $96.7 million during the Current Period
compared to $117.0 million during the Prior Period. The decrease was due
primarily to reduced operating income as a result of a decrease in average oil
and gas prices between periods.

Cash used in investing activities increased to $518.9 million during the Current
Period from $453.9 million in the Prior Period. The Company completed several
acquisitions requiring cash in the Current Period which totaled $345 million,
compared to none in the Prior Period, offset by a significant decrease in
drilling activity and leasehold acquisitions in the Current Period compared to
the Prior Period. During the Current Period the Company expended approximately
$143.8 million to initiate drilling on 166 gross (91.5 net) wells and invested
approximately $11.1 million in leasehold acquisitions. This compares to $254.4
million to initiate drilling on 140 gross (78.2 net) wells and $113.1 million to
purchase leasehold in the Prior Period.

Cash provided by financing activities was $367.9 million in the Current Period,
compared to $279.6 million in the Prior Period. During the Current Period, the
Company retired $465 million of debt consisting of $85 million of debt assumed
at the completion of the DLB acquisition, $120 million of debt assumed at the
completion of the Hugoton acquisition, $90 million of senior notes, and $170
million of borrowings made under its commercial bank credit facilities. The
Company issued $500 million in senior notes and $230 million in preferred stock.
During the Prior Period, the Company issued $300 million in Senior Notes.

The Company is subject to certain routine legal proceedings, none of which are
expected to have a material adverse effect upon the Company's financial
condition or operations. The Company is also a defendant in other non-routine
lawsuits, which are described in Note 3 of the notes to the accompanying
financial statements. Also see Part II, Item 1 of this report. An adverse
outcome in one or more of such suits could have a material effect on the
Company, although management is unable to quantify the Company's exposure to
liability. No provision for litigation liability has been recorded for these
non-routine lawsuits in the Company's financial statements.

YEAR 2000

Project. The Company has placed a high priority on proactively resolving
computer or imbedded chip problems related to the "Year 2000" which may have
adverse material effects on its continuing operations or cash flow. This problem
would be caused by the inability of a component (software, hardware or equipment
with embedded microprocessors) to correctly process date data in and between the
20th and 21st centuries and therefore fail to properly perform its intended
functions, and/or to exchange correct date data with other components. This
problem would most typically be caused by erroneous date calculations, which
results from using two digits to signify a year (century implied), handling leap
years incorrectly or the use of "special" values that can be confused with
legitimate calendar dates. The scope of the Year 2000 project includes
conducting an inventory of the Company's software, hardware and "embedded
systems" equipment, assessing potential for failure and the associated risk,
prioritizing the need for remediation, repairing or replacing significant
noncompliant items, and testing. In addition, the Company will take a similar
approach to mitigating risks associated with the Year 2000 readiness of material
business partners (vendors, suppliers, customers, etc.). The project will also
identify contingency plans to cope with unexpected events resulting from Year
2000 issues.

Beginning in mid 1997, the Company began an assessment of its core financial and
operational software systems. Three critical systems were identified with date
sensitivities: oil and gas financial accounting, production accounting and
land/lease administration. A Year 2000 compliant release of the oil and gas
financial accounting package in use at the Company is available and has been
scheduled for implementation during the first calendar quarter of 1999. The
production accounting system in use at the Company is also scheduled for upgrade
to a Year 2000 compliant version early in 1999. Both of these upgrades have been
scheduled to maintain currency with the respective vendors' support and to take
advantage of additional features and performance enhancements. A project has
been underway since early 1997 to implement a completely revamped version of the
land/lease administration package in use at the Company to provide significantly
increased functionality and reliability. The terms of this development
arrangement stipulated Year 2000 compliance and is being monitored. Assessment
continues for lower priority software systems.

In addition, the Year 2000 compliant AS/400, on which the accounting package
resides, was upgraded to provide additional capacity in late 1997. Operating
system upgrades will be implemented in the near future for the Windows NT based
servers to complete their remediation.

Other activities either already underway or scheduled to start during the
balance of 1998 include testing of desktop PC's, assessment of material business
partners, and inventory of embedded systems in field locations. The following
table summarizes the current overall status of the project with anticipated
completion dates:

In addition to the above, during the second quarter of 1999 the Company will
develop an overall contingency plan to assure continued operations which will
include precautionary measures.

Cost. To date, the Company has incurred only minor consulting costs for Year
2000 project planning and scope definition. All software packages requiring an
upgrade which have been identified will be upgraded within normal maintenance
procedures and will not require additional out of pocket expense. In all cases
these upgrades had been previously scheduled to maintain desired vendor support
and no upgrade project schedule has been accelerated to achieve Year 2000
compliance. An accurate cost cannot be determined prior to conclusion of the
Assessment/Prioritization phase, but it is expected total project expenditures
including the use of outside consultants should not exceed $1 million. This does
not include any costs which may be assessed by joint venture partners on
properties not operated by the Company.

Risks/Contingency. The failure to remediate critical systems (software, hardware
or embedded systems), or the failure of a material business partner to resolve
critical Year 2000 issues could have serious adverse impact on the ability of
the Company to continue operations and meet obligations. At the current time, it
is believed that any interruption in operation will be minor and short-lived and
will pose no safety or environmental risks. However, until all assessment phases
have been completed it is impossible to accurately identify the risks, quantify
potential impacts or establish a contingency plan. The Company has not yet
clearly identified the most likely worst case scenario if the Company and its
material business partners do not achieve Year 2000 compliance on a timely
basis. The Company currently intends to complete its contingency planning by
June 30, 1999.

                              AMENDED AND RESTATED
                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT is made effective July 1, 1998, between CHESAPEAKE
ENERGY CORPORATION, an Oklahoma corporation (the "Company"), and AUBREY K.
McCLENDON, an individual (the "Executive").

                              W I T N E S S E T H:

         WHEREAS, the Company and the Executive entered into that certain
employment agreement dated effective July 1, 1997 (the "Prior Agreement");

         WHEREAS, the Company has announced that it would explore strategic
alternatives to increase shareholder value, and to retain employees during that
process the Company adopted a retention program for the Company's key employees
other than the senior executive officers;

         WHEREAS, for the reasons the Company adopted the retention program for
the other employees, the Board of Directors of the Company believes that it is
in the best interests of the Company to provide for the retention of the
Executive as part of the process of exploring the Company's strategic
alternatives; and

         WHEREAS, the Company and the Executive desire to amend and restate the
Prior Agreement in its entirety.

         NOW, THEREFORE, in consideration of the mutual promises herein
contained, the Company and the Executive agree as follows:

1.       Employment. The Company hereby employs the Executive and the Executive
hereby accepts such employment subject to the terms and conditions contained in
this Agreement. The Executive is engaged as an employee of the Company, and the
Executive and the Company do not intend to create a joint venture, partnership
or other relationship which might impose a fiduciary obligation on the Executive
or the Company in the performance of this Agreement.

2.       Executive's Duties. The Executive is employed on a full-time basis.
Throughout the term of this Agreement, the Executive will use the Executive's
best efforts and due diligence to assist the Company in achieving the most
profitable operation of the Company and the Company's affiliated entities
consistent with developing and maintaining a quality business operation.

         2.1      Specific Duties.  The Executive will serve as Chairman of the
                  Board and Chief Executive Officer for the Company. From time
                  to time, the Executive may be appointed as an officer of one
                  (1) or more of the Company's subsidiaries. During the term of
                  this Agreement, the Executive will be nominated for election
                  or appointed to serve as a director of the Company and one (1)
                  or more of the Company's subsidiaries. The Executive will use
                  the Executive's best efforts to perform all of the services
                  required to fully and faithfully execute the offices and
                  positions to which the Executive is appointed and such other
                  services as may be reasonably directed by the board of
                  directors of the Company in accordance with this Agreement.

         2.2      Modifications. The precise duties to be performed by the
                  Executive may be extended or curtailed in the discretion of
                  the respective boards of directors of the Company. However,
                  except for termination for cause under paragraph 6.1.2 of this
                  Agreement, the failure of the Executive to be elected, be
                  reelected or serve as a director of the Company during the
                  term of this Agreement, the removal of the Executive as a
                  member of the board of directors of the Company, the
                  withdrawal of the designation of the Executive as Chairman of
                  the Board or Chief Executive Officer of the Company, or the
                  assignment of the performance of duties incumbent on the
                  foregoing offices to other persons without the prior written
                  consent of the Executive will constitute termination without
                  cause by the Company.

         2.3      Rules and Regulations. The Company currently has an Employment
                  Policies Manual which addresses frequently asked questions
                  regarding the Company. The Executive agrees to comply with the
                  Employment Policies Manual except to the extent inconsistent
                  with this Agreement. The Employment Policies Manual is subject
                  to change without notice in the sole discretion of the Company
                  at any time. In the event of a conflict between the Employment
                  Policies Manual and this Agreement, this Agreement will
                  control over the terms of the Employment Policies Manual.

         2.4      Stock Investment. For each calendar year during the term of
                  this Agreement the Executive agrees to hold shares of the
                  Company's common stock having an aggregate Investment Value
                  (as hereafter defined) equal to five hundred percent (500%) of
                  the compensation paid to the Executive under paragraphs 4.1
                  and 4.2 of this Agreement during such calendar year. Any
                  shares of common stock acquired by the Executive prior to the
                  date of this Agreement and still owned by the Executive during
                  the term of this Agreement may be used to satisfy this
                  requirement to own common stock. For purposes of this
                  paragraph, the "Investment Value" of each share of stock will
                  be as follows: (a) for shares purchased in the open market the
                  price paid by the Executive for such shares; (b) for shares
                  acquired through the exercise of stock options, the fair
                  market value of the common stock on the date the option was
                  exercised; and (c) for shares acquired other than through open
                  market purchases or the exercise of options the fair market
                  value of the Company's common stock on the date of the
                  acquisition of such common stock. The stock acquired or owned
                  pursuant to this paragraph 2.4 must be held by the Executive
                  at all times during the Executive's employment by the Company
                  or the Company's affiliated entities. In order to administer
                  this provision, the Executive agrees to deliver to the
                  Company's Chief Executive Officer a semi-annual report of
                  purchases and ownership in a form prepared by the Company.
                  This paragraph will become null and void if the Company's
                  common stock ceases to be listed on the New York Stock
                  Exchange, the National Association of Securities Dealers
                  Automated Quotation System or other national exchange. The
                  Company has no obligation to sell or to purchase from the
                  Executive any of the Company's stock in connection with this
                  paragraph 2.4 and has made no representations or warranties
                  regarding the Company's stock, operations or financial 
                  condition.

3.      Other Activities. Except for the activities (the "Permitted Activities")
expressly permitted by paragraphs 3.1 and 3.2 of this Agreement, or the prior
written approval of the board of directors of the Company, the Executive will
not: (a) engage in business independent of the Executive's employment by the
Company which requires any substantial portion of the Executive's time; (b)
serve as an officer or director of any corporation, partnership, company, or
firm; (c) except for passive investments that do not violate this Agreement and
require a minimal portion of the Executive's time, serve as a general partner or
member of any corporation, partnership, company or firm; or (d) directly or
indirectly invest in, participate in or acquire an interest in any oil and gas
business, including, without limitation, (i) producing oil and gas, (ii)
drilling, owning or operating oil and gas leases or wells, (iii) providing
services or materials to the oil and gas industry, (iv) marketing or refining
oil or gas, or (v) owning any interest in any corporation, partnership, company
or entity which conducts any of the foregoing activities. The limitations in
this paragraph 3 will not prohibit an investment by the Executive in publicly
traded securities. Notwithstanding the foregoing, the Executive will be
permitted to participate in the following activities which will be deemed to be
approved by the Company, if such activities are undertaken in strict compliance
with this Agreement.

        3.1       Company's Activities. The Executive or the Executive's
                  designated affiliate will be permitted to acquire a working
                  interest in all of the wells spudded by the Company or the
                  Company's subsidiary corporations, partnerships or entities
                  (the "Program Wells") on the terms and conditions set forth
                  herein in any Calendar Quarter (as hereafter defined) during
                  the Participation Term (as hereafter defined). The Program
                  Wells include any well spudded during such Calendar Quarter in
                  which the Company or the Company's subsidiary corporations,
                  partnerships or entities participate as a nonoperator.

                  3.1.1    Amount of Participation.  On or before the date which
                           is thirty (30) days before the first (1st) day of
                           each Calendar Quarter, the Executive will provide
                           notice to the compensation committee of the Company's
                           board of directors of the Executive's intent to
                           participate in the Program Wells during the
                           succeeding Calendar Quarter and the approximate
                           percentage working interest which the Executive
                           proposes to participate with during such Calendar
                           Quarter (the "Approved Percentage"). The Executive's
                           Approved Percentage working interest participation
                           (determined without consideration of any carried
                           interest) in the Program Wells for any Calendar
                           Quarter will not exceed two and one-half percent
                           (2.5%) on an eight- eighths (8/8ths) basis. On
                           designation of the Approved Percentage for a Calendar
                           Quarter, the Executive will be deemed to have elected
                           to participate in each Program Well spudded during
                           such Calendar Quarter with a working interest equal
                           to the following applicable percentage determined on
                           a well-by-well basis (the "Minimum Participation"):
                           (a) the


                                       -3-
<PAGE>   7
                           Approved Percentage for each Operations Well, each
                           Program Well which does not fall within clause (b) of
                           this paragraph 3 1.1 and any Program Well which does
                           not fall within clause (c) of this paragraph 3.1.1;
                           (b) zero percent (0%) if the combined participation
                           in the Program Well by the Executive, Mr. Tom L. Ward
                           and Mr. Marcus C. Rowland with such individuals'
                           Approved Percentage under their respective employment
                           agreements causes the Company's working interest
                           (determined without consideration of any carried
                           interest) on the spud date for such Program Well to
                           be less than twelve and one-half percent (12.5%) on
                           an eight eighths (8/8ths) basis; or (c) subsequent to
                           a termination under paragraphs 6.1.1 or 6.3 of this
                           Agreement the lowest Approved Percentage elected by
                           the Executive subsequent to such termination. If
                           clause (b) of this paragraph 3.1.1 prohibits the
                           Executive's participation in a Program Well, then
                           Messrs. Ward and Rowland will not be entitled to
                           participate in such Program Well under their
                           employment agreements. An "Operations Well" means a
                           Program Well which falls within the provisions of
                           clause (b) of this paragraph 3.1.1, but for which the
                           Executive's participation is deemed necessary for the
                           Company to retain operations as determined by the
                           disinterested members of the compensation committee
                           of the Company's board of directors. If the Executive
                           fails to provide notice of the Executive's intent to
                           participate and the Executive's proposed
                           participation prior to the specified date as provided
                           herein, the amount of the Approved Percentage for the
                           Calendar Quarter will be deemed to be zero (0).

                  3.1.2    Conditions of Participation. The Participation by the
                           Executive in each Program Well will be on no better 
                           terms than the terms agreed to by unaffiliated third
                           party participants in connection with the acquisition
                           of an interest in such Program Well from the Company
                           or its subsidiary corporations, partnerships or 
                           entities. The Approved Percentage cannot be changed
                           during any Calendar Quarter without the prior
                           approval of the disinterested members of the
                           compensation committee of the Company's board of
                           directors. Any participation by the Executive under
                           this paragraph 3.1 is also conditioned upon the
                           Executive's participation in each Program Well
                           spudded during such Calendar Quarter in an amount
                           equal to the Minimum Participation. The Executive
                           hereby agrees to execute and deliver any documents
                           reasonably requested by the Company and hereby
                           appoints the Company as the Executive's agent and
                           attorney-in-fact to execute and deliver such
                           documents if the Executive fails or refuses to
                           execute such documents. The Executive further agrees
                           to pay all joint interest billings within one hundred
                           fifty (150) days after receipt. For purposes of this
                           Agreement, the term: (a) "Calendar Quarter" means the
                           three (3) month periods commencing on the first (1st)
                           day of January, April, July and October; and (b)
                           "Participation Term" means the term of this Agreement
                           plus five (5) years after a termination under
                           paragraphs 6.1.1 or 6.3 of this Agreement.

         3.2      Other Activities. The Executive currently conducts oil and gas

                  Chesapeake Production Company, an Oklahoma corporation
                  ("Production"), and Chesapeake/Wood Joint Venture ("Venture").
                  The Executive will be permitted to continue oil and gas
                  activities in such entities but only to the extent such
                  activities are conducted on oil and gas leases or interests
                  owned by the Executive, Investments, Production or Venture as
                  of July 1, 1995, or acquired by Investments, Production or
                  Venture from the Company. The interests acquired by
                  Investments shall be limited by the provisions of paragraph
                  3.1 of this Agreement. The Company also consents to the

                  Dollars ($350,000.00), will be paid to the Executive in equal
                  semi-monthly installments beginning July 15, 1998 during the
                  term of this Agreement.

         4.2      Bonus. In addition to the Base Salary described at paragraph
                  4.1 of this Agreement, the Company may periodically pay bonus
                  compensation to the Executive. Any bonus compensation will be
                  at the absolute discretion of the Company in such amounts and
                  at such times as the board of directors of the Company may
                  determine.

         4.3      Stock Options. In addition to the compensation set forth in

                  conditions thereof.

         4.4      Benefits.  The Company will provide the Executive such 
                  retirement benefits, reimbursement of reasonable expenditures
                  for dues, travel and entertainment and other benefits on terms
                  customarily provided by the Company from time to time. The
                  Company will also provide the Executive the opportunity to
                  apply for coverage under the Company's medical, life and
                  disability plans, if any. If the Executive is accepted for

                  coverage on the same terms as is customarily provided by the
                  Company to the plan participants as modified from time to
                  time. The following specific benefits will also be provided to

                           during the term of this Agreement. No additional
                           compensation will be paid for failure to take
                           vacation and no vacation may be carried forward from
                           one calendar year to another.

                  4.4.2    Membership Dues. The Company will reimburse the
                           Executive for: (a) the monthly dues necessary to
                           maintain a full membership in (1) golf and/or country
                           club in the Oklahoma City area selected by the
                           Executive; and (b) the reasonable cost of any
                           qualified business entertainment at such country
                           club. All other costs, including, without implied
                           limitation, any initiation costs, initial membership
                           costs, personal use and business entertainment
                           unrelated to the Company will be the sole obligation
                           of the Executive and the Company will have no
                           liability with respect to such amounts.

                  4.4.3    Automobile and Travel Allowance.  The Executive will
                           receive a monthly cash allowance in the amount of One
                           Thousand Five Hundred Dollars ($1,500.00) to defer a
                           portion of the Executive's cost of acquiring,
                           operating and maintaining an automobile for use in
                           the Executive's employment. Additionally, the
                           Executive will be entitled to utilize any aircraft
                           owned by the Company (whether in whole or in part)
                           for personal use and will not be required to
                           reimburse the Company for any cost related to such
                           use or pay any cost or charge with respect to such
                           use up to an amount during any calendar year equal to
                           the Aircraft Allowance. For purposes of this
                           Agreement the term "Aircraft Allowance" means the
                           variable costs directly identifiable with each use
                           (including fuel, pilot charges, landing fees, hourly
                           charges under co-ownership arrangements and other
                           such costs) but specifically excludes any fixed costs
                           of the aircraft (including acquisition costs and
                           depreciation). The Aircraft Allowance will be equal
                           to $40,000.00 for the Company's fiscal year ending on
                           June 30, 1998, $25,000.00 for the six month period
                           ending on December 31, 1998, and $50,000.00 for each
                           fiscal year thereafter during the term of this
                           Agreement. If the Executive's use of the Company's
                           aircraft exceeds the Aircraft Allowance during any
                           fiscal year the Executive will be required to
                           reimburse the Company for the variable costs directly
                           identified with each such use.

                  4.4.4    Accounting Support. The Executive will be permitted
                           to utilize the Company's office space, computer
                           facilities and the equivalent of one (1) full-time
                           accounting employee of the Company (presently Ms.
                           Linda Peterburs) to maintain books and records for
                           the Executive and the Executive's Permitted
                           Activities. The Executive will not be required to pay
                           any compensation to the Company in connection with
                           such accounting services.

         4.5      Compensation Review. The compensation of the Executive will be
                  reviewed not less frequently than annually by the board of
                  directors of the Company. The compensation of the Executive
                  prescribed by paragraph 4 of this Agreement may be increased
                  at the discretion of the Company, but may not be reduced
                  without the prior written consent of the Executive.

5.       Term. In the absence of termination as set forth in paragraph 6 below,
this Agreement will extend for a term of five (5) years commencing on July 1,
1998, and ending on June 30, 2003 (the "Expiration Date") as extended from time
to time. Unless the Company provides thirty (30) days prior written notice of
nonextension to the Executive, on each June 30 during the term of this
Agreement, the term and the Expiration Date will be automatically extended for
one (1) additional year so that the remaining term on this Agreement will be not
less than four (4) and not more than five (5) years.

6.       Termination. This Agreement will continue in effect until the
expiration of the term set forth in paragraph 5 of this Agreement unless earlier
terminated pursuant to this paragraph 6.

         6.1      Termination by Company. The Company will have the following
                  rights to terminate this Agreement:

                  6.1.1    Termination without Cause.  The Company may terminate
                           this Agreement without cause at any time by the
                           service of written notice of termination to the
                           Executive specifying an effective date of such
                           termination not sooner than sixty (60) business days
                           after the date of such notice (the "Termination
                           Date"). In the event the Executive is terminated
                           without cause (other than a CC Termination under
                           paragraph 6.3 of this Agreement), the Executive will
                           receive as termination compensation: (a) Base
                           Compensation (as hereafter defined) during the
                           remaining term of this Agreement, but in any event
                           through the Expiration Date; (b) any benefits payable
                           by operation of paragraph 4.4 of this Agreement
                           during the remaining term of this Agreement, but in
                           any event through the Expiration Date; and (c) any
                           vacation pay accrued through the Termination Date.
                           For purposes of this Agreement the term "Base
                           Compensation" means the Executive's current Base
                           Salary under paragraph 4.1 on the Termination Date
                           plus the bonus compensation received by the Executive
                           during the twelve (12) month period preceding the
                           Termination Date.

                  6.1.2    Termination for Cause. The Company may terminate this
                           Agreement for cause if the Executive: (a)
                           misappropriates the property of the Company or
                           commits any other act of dishonesty; (b) engages in
                           personal misconduct which materially injures the
                           Company; (c) willfully violates any law or regulation
                           relating to the business of the Company which results
                           in injury to the Company; or (d) willfully and
                           repeatedly fails to perform the Executive's duties
                           hereunder. In the event this Agreement is terminated
                           for


                                       -7-
<PAGE>   11
                           cause, the Company will not have any obligation to
                           provide any further payments or benefits to the
                           Executive after the effective date of such
                           termination. This Agreement will not be deemed to
                           have terminated for cause unless a written
                           determination specifying the reasons for such
                           termination is made, approved by a majority of the
                           disinterested members of the board of directors of
                           the Company and delivered to the Executive.
                           Thereafter, the Executive will have the right for a
                           period of twenty (20) days to request a board of
                           directors meeting to be held at a mutually agreeable
                           time and location within thirty (30) days, at which
                           meeting the Executive will have an opportunity to be
                           heard. Failing such determination and opportunity for
                           hearing, any termination of this Agreement will be
                           deemed to have occurred without cause.

         6.2      Termination by Executive. The Executive may voluntarily
                  terminate this Agreement with or without cause by the service
                  of written notice of such termination to the Company
                  specifying an effective date of such termination sixty (60)
                  days after the date of such notice, during which time
                  Executive may use remaining accrued vacation days, or at the
                  Company's option, be paid for such days. In the event this
                  Agreement is terminated by the Executive, neither the Company
                  nor the Executive will have any further obligations hereunder
                  including, without limitation, any obligation of the Company
                  to provide any further payments or benefits to the Executive
                  after the effective date of such termination.

         6.3      Termination After Change in Control. If during the term of
                  this Agreement there is a "Change of Control" and within two
                  (2) years thereafter there is a CC Termination (as hereafter
                  defined) then the Executive will be entitled to a severance
                  payment (in addition to any other rights and other amounts
                  payable to the Executive under this Agreement or otherwise) in
                  an amount equal to the sum of the following: (a) five (5)
                  times the Executive's Base Compensation; plus (b) the Gross-up
                  Amount (as hereafter defined). If the foregoing amount is not
                  paid within ten (10) days after the CC Termination, the unpaid
                  amount will bear interest at the per annum rate equal to the
                  prime rate published from time to time in the Wall Street
                  Journal. The interest rate will be adjusted on the date of a
                  change in such prime rate. For purposes of this Agreement the
                  term "Gross-up Amount" means the amount of the payment which
                  will result in the Executive retaining from such payment
                  (after paying all taxes imposed on such payment and any
                  interest or penalties related to such taxes) an amount equal
                  to any excise tax imposed by Section 4999 of the Internal
                  Revenue Code of 1986, as amended, together with any interest
                  and penalties with respect to such excise tax imposed on the
                  all of the payments made to the Executive under this paragraph
                  6.3.

                  6.3.1    Change of Control. The term "Change of Control" means
                           any action of a nature that would be required to be
                           reported in response to Item 6(e) of Schedule 14A of
                           Regulation 14A under the Securities Exchange Act of
                           1934


                                       -8-

                           with respect to the Company including, without
                           limitation (i) the direct or indirect acquisition by
                           any person after the date hereof of beneficial
                           ownership of the right to vote or securities of the
                           Company representing the right to vote thirty five
                           percent (35%) or more of the combined voting power of
                           the Company's then outstanding securities having the
                           right to vote for the election of directors, or (ii)
                           within two years of a tender offer or exchange offer
                           for the voting stock of the Company or as a result of
                           a merger, consolidation, sale of assets or contested
                           election (or any combination of the foregoing), a
                           majority of the members of the Company's board of
                           directors is replaced by directors who were not
                           nominated and approved by the board of directors.

                  6.3.2    CC Termination.  The term "CC Termination" means any
                           of the following: (a) this Agreement expires in

                           extended under paragraph 5 of this Agreement and the
                           Executive resigns within one (1) year after such
                           nonextension; (c) the Executive is terminated by the
                           Company other than under paragraphs 6.1.2, 6.4 or 6.5

                           as a result of a change in the Executive's duties, a
                           reduction in the Executive's then current
                           compensation, a required relocation more than 25
                           miles from the Executive's then current place of
                           employment or a default by the Company under this
                           Agreement; (e) the failure by the Company after a
                           Change of Control to obtain the assumption of this

                           successor to the Company or any parent corporation of
                           the Company; or (f) after a Change of Control has
                           occurred, the Executive agrees to remain employed by
                           the Company for a period of three (3) months to
                           assist in the transition and thereafter resigns.

         6.4      Incapacity of Executive. If the Executive suffers from a
                  physical or mental condition which in the reasonable judgment
                  of the Company's board of directors prevents the Executive in
                  whole or in part from performing the duties specified herein
                  for a period of three (3) consecutive months, the Executive
                  may be terminated. Although the termination shall be deemed as
                  a termination with cause, any compensation payable under
                  paragraph 4 of this Agreement will be continued through the
                  remaining term of this Agreement, but in any event through the
                  Expiration Date. Notwithstanding the foregoing, the
                  Executive's Base Salary specified in paragraph 4.1 of this
                  Agreement will be reduced by any benefits payable under any
                  disability plans provided by the Company under paragraph 4 of
                  this Agreement.

         6.5      Death of Executive. If the Executive dies during the term of
                  this Agreement, the Company may thereafter terminate this
                  Agreement without compensation to the Executive's estate
                  except: (a) the obligation to continue the Base Salary
                  payments under paragraph 4.1 of this Agreement for twelve (12)
                  months after the effective date of such termination, and (b)
                  the benefits described in paragraph 4.4 of this Agreement
                  accrued through the effective date of such termination.

         6.6      Effect of Termination. The termination of this Agreement will
                  terminate all obligations of the Executive to render services
                  on behalf of the Company, provided that the Executive will
                  maintain the confidentiality of all information acquired by
                  the Executive during the term of his employment in accordance
                  with paragraph 7 of this Agreement. In the event of a
                  termination under paragraphs 6.1.1 or 6.3 of this Agreement
                  the Executive's right to participate in Program Wells will
                  continue in accordance with paragraph 3 of this Agreement.
                  Except as otherwise provided in this paragraph 6, no accrued
                  bonus, severance pay or other form of compensation will be
                  payable by the Company to the Executive by reason of the
                  termination of this Agreement. All keys, entry cards, credit
                  cards, files, records, financial information, furniture,
                  furnishings, equipment, supplies and other items relating to
                  the Company will remain the property of the Company. The
                  Executive will have the right to retain and remove all
                  personal property and effects which are owned by the Executive
                  and located in the offices of the Company. All such personal
                  items will be removed from such offices no later than seven
                  (7) days after the effective date of termination, and the
                  Company is hereby authorized to discard any items remaining
                  and to reassign the Executive's office space after such date.
                  Prior to the effective date of termination, the Executive will
                  render such services to the Company as might be reasonably
                  required to provide for the orderly termination of the
                  Executive's employment.

7.       Confidentiality. The Executive recognizes that the nature of the
Executive's services are such that the Executive will have access to information
which constitutes trade secrets, is of a confidential nature, is of great value
to the Company or is the foundation on which the business of the Company is
predicated. The Executive agrees not to disclose to any person other than the
Company's employees or the Company's legal counsel nor use for any purpose,
other than the performance of this Agreement, any confidential information
("Confidential Information"). Confidential Information includes data or material
(regardless of form) which is: (a) a trade secret; (b) provided, disclosed or
delivered to Executive by the Company, any officer, director, employee, agent,
attorney, accountant, consultant, or other person or entity employed by the
Company in any capacity, any customer, borrower or business associate of the
Company or any public authority having jurisdiction over the Company of any
business activity conducted by the Company; or (c) produced, developed, obtained
or prepared by or on behalf of Executive or the Company (whether or not such
information was developed in the performance of this Agreement) with respect to
the Company or any assets oil and gas prospects, business activities, officers,
directors, employees, borrowers or customers of the foregoing. However,
Confidential Information shall not include any information, data or material
which at the time of disclosure or use was generally available to the public
other than by a breach of this Agreement, was available to the party to whom
disclosed on a non-confidential basis by disclosure or access provided by the
Company or a third party, or was otherwise developed or obtained independently
by the person to whom disclosed without a breach of this Agreement. On request
by the Company, the


                                      -10-
<PAGE>   14
Company will be entitled to a copy of any Confidential Information in the
possession of the Executive. The Executive also agrees that the provisions of
this paragraph 7 will survive the termination, expiration or cancellation of
this Agreement for a period of five (5) years. The Executive will deliver to the
Company all originals and copies of the documents or materials containing
Confidential Information. For purposes of paragraphs 7, 8, and 9 of this
Agreement, the Company expressly includes any of the Company's affiliated
corporations, partnerships or entities.

8.       Noncompetition. For a period of twelve (12) months after Executive is
no longer employed by the Company as a result of either the resignation by the
Executive pursuant to paragraph 6.2 above or termination for cause pursuant to
paragraph 6.1.2 above, the Executive will not: (a) acquire, attempt to acquire
or aid another in the acquisition or attempted acquisition of an interest in oil
and gas assets, oil and gas production, oil and gas leases, mineral interests,
oil and gas wells or other such oil and gas exploration, development or
production activities within five (5) miles of any operations or ownership
interests of the Company or its subsidiary corporations, partnerships or
entities (but excluding operations or ownership interests acquired by the
Company from a successor entity through a Change of Control as described in
paragraph 6.3); and (b) solicit, induce, entice or attempt to entice any
employee, contractor, customer, vendor or subcontractor to terminate or breach
any relationship with the Company or the Company's affiliates for the
Executive's own account or for the benefit of another party. The Executive
further agrees that the Executive will not circumvent or attempt to circumvent
the foregoing agreements by any future arrangement or through the actions of a
third party.

9.       Proprietary Matters. The Executive expressly understands and agrees
that any and all improvements, inventions, discoveries, processes or know-how
that are generated or conceived by the Executive during the term of this
Agreement, whether generated or conceived during the Executive's regular working
hours or otherwise, will be the sole and exclusive property of the Company.
Whenever requested by the Company (either during the term of this Agreement or
thereafter), the Executive will assign or execute any and all applications,
assignments and or other instruments and do all things which the Company deems
necessary or appropriate in order to permit the Company to: (a) assign and
convey or otherwise make available to the Company the sole and exclusive right,
title, and interest in and to said improvements, inventions, discoveries,
processes, know-how, applications, patents, copyrights, trade names or
trademarks; or (b) apply for, obtain, maintain, enforce and defend patents,
copyrights, trade names, or trademarks of the United States or of foreign
countries for said improvements, inventions, discoveries, processes or know-how.
However, the improvements, inventions, discoveries, processes or know-how
generated or conceived by the Executive and referred to above (except as they
may be included in the patents, copyrights or registered trade names or
trademarks of the Company, or corporations, partnerships or other entities which
may be affiliated with the Company) shall not be exclusive property of the
Company at any time after having been disclosed or revealed or have otherwise
become available to the public or to a third party on a non-confidential basis
other than by a breach of this Agreement, or after they have been independently
developed or discussed without a breach of this Agreement by a third party who
has no obligation to the Company or its affiliates.

10.      Arbitration. The parties will attempt to promptly resolve any dispute
or controversy arising out of or relating to this Agreement or termination of
the Executive by the Company. Any negotiations pursuant to this paragraph 10 are
confidential and will be treated as compromise and settlement negotiations for
all purposes. If the parties are unable to reach a settlement amicably, the
dispute will be submitted to binding arbitration before a single arbitrator in
accordance with the Employment Dispute Resolution Rules of the American
Arbitration Association. The arbitrator will be instructed and empowered to take
reasonable steps to expedite the arbitration and the arbitrator's judgment will
be final and binding upon the parties subject solely to challenge on the grounds
of fraud or gross misconduct. Except for damages arising out of a breach of
paragraphs 6, 7, 8 or 9 of this Agreement, the arbitrator is not empowered to
award total damages (including compensatory damages) which exceed 300% of
compensatory damages and each party hereby irrevocably waives any damages in
excess of that amount. The arbitration will be held in Oklahoma County,
Oklahoma. Judgment upon any verdict in arbitration may be entered in any court
of competent jurisdiction and the parties hereby consent to the jurisdiction of,
and proper venue in, the federal and state courts located in Oklahoma County,
Oklahoma. Each party will bear its own costs in connection with the arbitration
and the costs of the arbitrator will be borne by the party who the arbitrator
determines did not prevail in the matter. Unless otherwise expressly set forth
in this Agreement, the procedures specified in this paragraph 10 will be the
sole and exclusive procedures for the resolution of disputes and controversies
between the parties arising out of or relating to this Agreement.
Notwithstanding the foregoing, a party may seek a preliminary injunction or
other provisional judicial relief if in such party's judgment such action is
necessary to avoid irreparable damage or to preserve the status quo.

11.      Miscellaneous. The parties further agree as follows:

         11.1     Time. Time is of the essence of each provision of this
                  Agreement.

         11.2     Notices. Any notice, payment, demand or communication required
                  or permitted to be given by any provision of this Agreement
                  will be in writing and will be deemed to have been given when
                  delivered personally or by telefacsimile to the party

                  such other or additional addresses as any party might
                  designate by written notice to the other party:

         11.3     Assignment. Neither this Agreement nor any of the parties'
                  rights or obligations hereunder can be transferred or assigned
                  without the prior written consent of the other parties to this
                  Agreement.

         11.4     Construction. If any provision of this Agreement or the
                  application thereof to any person or circumstances is
                  determined, to any extent, to be invalid or unenforceable, the
                  remainder of this Agreement, or the application of such
                  provision to persons or circumstances other than those as to
                  which the same is held invalid or unenforceable, will not be
                  affected thereby, and each term and provision of this
                  Agreement will be valid and enforceable to the fullest extent
                  permitted by law. This Agreement is intended to be
                  interpreted, construed and enforced in accordance with the
                  laws of the State of Oklahoma and any litigation relating to
                  this Agreement will be conducted in a court of competent
                  jurisdiction sitting in Oklahoma County, Oklahoma.

         11.5     Entire Agreement. Except as provided in paragraph 2.3 of this
                  Agreement, this Agreement constitutes the entire agreement
                  between the parties hereto with respect to the subject matter
                  herein contained, and no modification hereof will be effective
                  unless made by a supplemental written agreement executed by
                  all of the parties hereto.

         11.6     Binding Effect. This Agreement will be binding on the parties
                  and their respective successors, legal representatives and
                  permitted assigns. In the event of a merger, consolidation,
                  combination, dissolution or liquidation of the Company, the
                  performance of this Agreement will be assumed by any entity
                  which succeeds to or is transferred the business of the
                  Company as a result thereof.

         11.7     Attorneys' Fees. If any party institutes an action or
                  proceeding against any other party relating to the provisions
                  of this Agreement or any default hereunder, the unsuccessful
                  party to such action or proceeding will reimburse the
                  successful party therein for the reasonable expenses of
                  attorneys' fees and disbursements and litigation expenses
                  incurred by the successful party.

         11.8     Supercession. This Agreement is the final, complete and
                  exclusive expression of the agreement between the Company and
                  the Executive and supersedes and replaces in all respects any
                  prior employment agreements (including the Prior Agreement).
                  On execution of this Agreement by the Company and the
                  Executive, the relationship between the Company and the
                  Executive after the effective date of this Agreement will be
                  governed by the terms of this Agreement and not by any other
                  agreements, oral or otherwise.

                              AMENDED AND RESTATED
                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT is made effective July 1, 1998, between CHESAPEAKE
ENERGY CORPORATION, an Oklahoma corporation (the "Company"), and TOM L. WARD, an
individual (the "Executive").

                              W I T N E S S E T H:

         WHEREAS, the Company and the Executive entered into that certain
employment agreement dated effective July 1, 1997 (the "Prior Agreement");

         WHEREAS, the Company has announced that it would explore strategic
alternatives to increase shareholder value, and to retain employees during that
process the Company adopted a retention program for the Company's key employees
other than the senior executive officers;

         WHEREAS, for the reasons the Company adopted the retention program for
the other employees, the Board of Directors of the Company believes that it is
in the best interests of the Company to provide for the retention of the
Executive as part of the process of exploring the Company's strategic
alternatives; and

         WHEREAS, the Company and the Executive desire to amend and restate the
Prior Agreement in its entirety.

         NOW, THEREFORE, in consideration of the mutual promises herein
contained, the Company and the Executive agree as follows:

1.       Employment. The Company hereby employs the Executive and the Executive
hereby accepts such employment subject to the terms and conditions contained in
this Agreement. The Executive is engaged as an employee of the Company, and the
Executive and the Company do not intend to create a joint venture, partnership
or other relationship which might impose a fiduciary obligation on the Executive
or the Company in the performance of this Agreement.

2.       Executive's Duties. The Executive is employed on a full-time basis.
Throughout the term of this Agreement, the Executive will use the Executive's
best efforts and due diligence to assist the Company in achieving the most
profitable operation of the Company and the Company's affiliated entities
consistent with developing and maintaining a quality business operation.

         2.1      Specific Duties. The Executive will serve as President and
                  Chief Operating Officer for the Company. From time to time,
                  the Executive may be appointed as an officer of one (1) or
                  more of the Company's subsidiaries. During the term of this
                  Agreement, the Executive will be nominated for election or
                  appointed to serve as a director of the Company and one (1) or
                  more of the Company's subsidiaries. The Executive will use the
                  Executive's best efforts to perform all of the services
                  required to fully and faithfully execute the offices and
                  positions to which the Executive is appointed and such other
                  services as may be reasonably directed by the board of
                  directors of the Company in accordance with this Agreement.

         2.2      Modifications. The precise duties to be performed by the
                  Executive may be extended or curtailed in the discretion of
                  the respective boards of directors of the Company. However,
                  except for termination for cause under paragraph 6.1.2 of this
                  Agreement, the failure of the Executive to be elected, be
                  reelected or serve as a director of the Company during the
                  term of this Agreement, the removal of the Executive as a
                  member of the board of directors of the Company, the
                  withdrawal of the designation of the Executive as President or
                  Chief Operating Officer of the Company, or the assignment of
                  the performance of duties incumbent on the foregoing offices
                  to other persons without the prior written consent of the
                  Executive will constitute termination without cause by the
                  Company.

         2.3      Rules and Regulations. The Company currently has an Employment
                  Policies Manual which addresses frequently asked questions
                  regarding the Company. The Executive agrees to comply with the
                  Employment Policies Manual except to the extent inconsistent
                  with this Agreement. The Employment Policies Manual is subject
                  to change without notice in the sole discretion of the Company
                  at any time. In the event of a conflict between the Employment
                  Policies Manual and this Agreement, this Agreement will
                  control over the terms of the Employment Policies Manual.

         2.4      Stock Investment. For each calendar year during the term of
                  this Agreement the Executive agrees to hold shares of the
                  Company's common stock having an aggregate Investment Value
                  (as hereafter defined) equal to five hundred percent (500%) of
                  the compensation paid to the Executive under paragraphs 4.1
                  and 4.2 of this Agreement during such calendar year. Any
                  shares of common stock acquired by the Executive prior to the
                  date of this Agreement and still owned by the Executive during
                  the term of this Agreement may be used to satisfy this
                  requirement to own common stock. For purposes of this
                  paragraph, the "Investment Value" of each share of stock will
                  be as follows: (a) for shares purchased in the open market the
                  price paid by the Executive for such shares; (b) for shares
                  acquired through the exercise of stock options, the fair
                  market value of the common stock on the date the option was
                  exercised; and (c) for shares acquired other than through open
                  market purchases or the exercise of options the fair market
                  value of the Company's common stock on the date of the
                  acquisition of such common stock. The stock acquired or owned
                  pursuant to this paragraph 2.4 must be held by the Executive
                  at all times during the Executive's employment by the Company
                  or the Company's affiliated entities. In order to administer
                  this provision, the Executive agrees to deliver to the
                  Company's Chief Executive Officer a semi-annual report of
                  purchases and ownership in a form prepared by the Company.
                  This paragraph will become null and void if the Company's
                  common


                                       -2-

                  stock ceases to be listed on the New York Stock Exchange, the
                  National Association of Securities Dealers Automated Quotation
                  System or other national exchange. The Company has no
                  obligation to sell or to purchase from the Executive any of
                  the Company's stock in connection with this paragraph 2.4 and
                  has made no representations or warranties regarding the
                  Company's stock, operations or financial condition.

3.      Other Activities. Except for the activities (the "Permitted Activities")
expressly permitted by paragraphs 3.1 and 3.2 of this Agreement, or the prior
written approval of the board of directors of the Company, the Executive will
not: (a) engage in business independent of the Executive's employment by the
Company which requires any substantial portion of the Executive's time; (b)
serve as an officer or director of any corporation, partnership, company, or
firm; (c) except for passive investments that do not violate this Agreement and
require a minimal portion of the Executive's time, serve as a general partner or
member of any corporation, partnership, company or firm; or (d) directly or
indirectly invest in, participate in or acquire an interest in any oil and gas
business, including, without limitation, (i) producing oil and gas, (ii)
drilling, owning or operating oil and gas leases or wells, (iii) providing
services or materials to the oil and gas industry, (iv) marketing or refining
oil or gas, or (v) owning any interest in any corporation, partnership, company
or entity which conducts any of the foregoing activities. The limitations in
this paragraph 3 will not prohibit an investment by the Executive in publicly
traded securities. Notwithstanding the foregoing, the Executive will be
permitted to participate in the following activities which will be deemed to be
approved by the Company, if such activities are undertaken in strict compliance
with this Agreement.

        3.1       Company's Activities. The Executive or the Executive's
                  designated affiliate will be permitted to acquire a working
                  interest in all of the wells spudded by the Company or the
                  Company's subsidiary corporations, partnerships or entities
                  (the "Program Wells") on the terms and conditions set forth
                  herein in any Calendar Quarter (as hereafter defined) during
                  the Participation Term (as hereafter defined). The Program
                  Wells include any well spudded during such Calendar Quarter in
                  which the Company or the Company's subsidiary corporations,
                  partnerships or entities participate as a nonoperator.

                  3.1.1    Amount of Participation.  On or before the date which
                           is thirty (30) days before the first (1st) day of
                           each Calendar Quarter, the Executive will provide
                           notice to the compensation committee of the Company's
                           board of directors of the Executive's intent to
                           participate in the Program Wells during the
                           succeeding Calendar Quarter and the approximate
                           percentage working interest which the Executive
                           proposes to participate with during such Calendar
                           Quarter (the "Approved Percentage"). The Executive's
                           Approved Percentage working interest participation
                           (determined without consideration of any carried
                           interest) in the Program Wells for any Calendar
                           Quarter will not exceed two and one-half percent
                           (2.5%) on an eight-

<PAGE>   7
                           eighths (8/8ths) basis. On designation of the
                           Approved Percentage for a Calendar Quarter, the
                           Executive will be deemed to have elected to
                           participate in each Program Well spudded during such
                           Calendar Quarter with a working interest equal to the
                           following applicable percentage determined on a
                           well-by-well basis (the "Minimum Participation"): (a)
                           the Approved Percentage for each Operations Well,
                           each Program Well which does not fall within clause
                           (b) of this paragraph 3 1.1 and any Program Well
                           which does not fall within clause (c) of this
                           paragraph 3.1.1; (b) zero percent (0%) if the
                           combined participation in the Program Well by the
                           Executive, Mr. Tom L. Ward and Mr. Marcus C. Rowland
                           with such individuals' Approved Percentage under
                           their respective employment agreements causes the
                           Company's working interest (determined without
                           consideration of any carried interest) on the spud
                           date for such Program Well to be less than twelve and
                           one-half percent (12.5%) on an eight- eighths
                           (8/8ths) basis; or (c) subsequent to a termination
                           under paragraphs 6.1.1 or 6.3 of this Agreement the
                           lowest Approved Percentage elected by the Executive
                           subsequent to such termination. If clause (b) of this
                           paragraph 3.1.1 prohibits the Executive's
                           participation in a Program Well, then Messrs. Ward
                           and Rowland will not be entitled to participate in
                           such Program Well under their employment agreements.
                           An "Operations Well" means a Program Well which falls
                           within the provisions of clause (b) of this paragraph
                           3.1.1, but for which the Executive's participation is
                           deemed necessary for the Company to retain operations
                           as determined by the disinterested members of the
                           compensation committee of the Company's board of
                           directors. If the Executive fails to provide notice
                           of the Executive's intent to participate and the
                           Executive's proposed participation prior to the
                           specified date as provided herein, the amount of the
                           Approved Percentage for the Calendar Quarter will be
                           deemed to be zero (0).

                  3.1.2    Conditions of Participation. The Participation by the
                           Executive in each Program Well will be on no better
                           terms than the terms agreed to by unaffiliated third
                           party participants in connection with the acquisition
                           of an interest in such Program Well from the Company
                           or its subsidiary corporations, partnerships or
                           entities. The Approved Percentage cannot be changed
                           during any Calendar Quarter without the prior
                           approval of the disinterested members of the
                           compensation committee of the Company's board of
                           directors. Any participation by the Executive under
                           this paragraph 3.1 is also conditioned upon the
                           Executive's participation in each Program Well
                           spudded during such Calendar Quarter in an amount
                           equal to the Minimum Participation. The Executive
                           hereby agrees to execute and deliver any documents
                           reasonably requested by the Company and hereby
                           appoints the Company as the Executive's agent and
                           attorney-in-fact to execute and deliver such
                           documents if the Executive fails or refuses to


                                       -4-

<PAGE>   8
                           execute such documents. The Executive further agrees
                           to pay all joint interest billings within one hundred
                           fifty (150) days after receipt. For purposes of this
                           Agreement, the term: (a) "Calendar Quarter" means the
                           three (3) month periods commencing on the first (1st)
                           day of January, April, July and October; and (b)
                           "Participation Term" means the term of this Agreement
                           plus five (5) years after a termination under
                           paragraphs 6.1.1 or 6.3 of this Agreement.

         3.2      Other Activities. The Executive currently conducts oil and gas
                  investment activities individually and through TLW
                  Investments, Inc., ("Investments"). The Executive will be
                  permitted to continue oil and gas activities in such entities
                  but only to the extent such activities are conducted on oil
                  and gas leases or interests owned by the Executive or
                  Investments as of July 1, 1995, or acquired by Investments
                  from the Company. The interests acquired by Investments shall
                  be limited by the provisions of paragraph 3.1 of this
                  Agreement. The Company also consents to the Executive serving
                  as a director of Pan East Petroleum Corp., an Ontario Canada
                  corporation, pursuant to approval by the board of directors.

4.       Executive's Compensation. The Company agrees to compensate the 
Executive as follows:

         4.1      Base Salary. A base salary (the "Base Salary"), at the initial
                  annual rate of not less than Three Hundred Fifty Thousand
                  Dollars ($350,000.00), will be paid to the Executive in equal
                  semi-monthly installments beginning July 15, 1998 during the
                  term of this Agreement.

         4.2      Bonus. In addition to the Base Salary described at paragraph
                  4.1 of this Agreement, the Company may periodically pay bonus
                  compensation to the Executive. Any bonus compensation will be
                  at the absolute discretion of the Company in such amounts and
                  at such times as the board of directors of the Company may
                  determine.

         4.3      Stock Options. In addition to the compensation set forth in
                  paragraphs 4.1 and 4.2 of this Agreement, the Executive may
                  periodically receive grants of stock options from the
                  Company's various stock option plans, subject to the terms and
                  conditions thereof.

         4.4      Benefits.  The Company will provide the Executive such
                  retirement benefits, reimbursement of reasonable expenditures
                  for dues, travel and entertainment and other benefits on terms
                  customarily provided by the Company from time to time. The
                  Company will also provide the Executive the opportunity to
                  apply for coverage under the Company's medical, life and
                  disability plans, if any. If the Executive is accepted for
                  coverage under such plans, the Company will provide such
                  coverage on the same terms as is customarily provided by the
                  Company to the plan participants as modified from time to
                  time. The following specific benefits will also be provided to
                  the Executive at the expense of the Company:

                  4.4.1    Vacation. The Executive will be entitled to take
                           three (3) weeks of paid vacation each calendar year
                           during the term of this Agreement. No additional
                           compensation will be paid for failure to take
                           vacation and no vacation may be carried forward from
                           one calendar year to another.

                  4.4.2    Membership Dues. The Company will reimburse the 
                           Executive for: (a) the monthly dues necessary to
                           maintain a full membership in (1) golf and/or country
                           club in the Oklahoma City area selected by the
                           Executive; and (b) the reasonable cost of any
                           qualified business entertainment at such country
                           club. All other costs, including, without implied
                           limitation, any initiation costs, initial membership
                           costs, personal use and business entertainment
                           unrelated to the Company will be the sole obligation
                           of the Executive and the Company will have no
                           liability with respect to such amounts.

                  4.4.3    Automobile and Travel Allowance.  The Executive will
                           receive a monthly cash allowance in the amount of One
                           Thousand Five Hundred Dollars ($1,500.00) to defer a
                           portion of the Executive's cost of acquiring,
                           operating and maintaining an automobile for use in
                           the Executive's employment. Additionally, the
                           Executive will be entitled to utilize any aircraft
                           owned by the Company (whether in whole or in part)
                           for personal use and will not be required to
                           reimburse the Company for any cost related to such
                           use or pay any cost or charge with respect to such
                           use up to an amount during any calendar year equal to
                           the Aircraft Allowance. For purposes of this
                           Agreement the term "Aircraft Allowance" means the
                           variable costs directly identifiable with each use
                           (including fuel, pilot charges, landing fees, hourly
                           charges under co-ownership arrangements and other
                           such costs) but specifically excludes any fixed costs
                           of the aircraft (including acquisition costs and
                           depreciation). The Aircraft Allowance will be equal
                           to $40,000.00 for the Company's fiscal year ending on
                           June 30, 1998, $25,000.00 for the six month period
                           ending on December 31, 1998, and $50,000.00 for each
                           fiscal year thereafter during the term of this
                           Agreement. If the Executive's use of the Company's
                           aircraft exceeds the Aircraft Allowance during any
                           fiscal year the Executive will be required to
                           reimburse the Company for the variable costs directly
                           identified with each such use.

                  4.4.4    Accounting Support. The Executive will be permitted
                           to utilize the Company's office space, computer
                           facilities and the equivalent of one (1) full-time
                           accounting employee of the Company (presently Ms.
                           Cheryl Hamilton) to maintain books and records for
                           the Executive and the

                           Executive's Permitted Activities. The Executive will
                           not be required to pay any compensation to the
                           Company in connection with such accounting services.

         4.5      Compensation Review. The compensation of the Executive will be
                  reviewed not less frequently than annually by the board of
                  directors of the Company. The compensation of the Executive
                  prescribed by paragraph 4 of this Agreement may be increased
                  at the discretion of the Company, but may not be reduced
                  without the prior written consent of the Executive.

5.       Term. In the absence of termination as set forth in paragraph 6 below,
this Agreement will extend for a term of five (5) years commencing on July 1,
1998, and ending on June 30, 2003 (the "Expiration Date") as extended from time
to time. Unless the Company provides thirty (30) days prior written notice of
nonextension to the Executive, on each June 30 during the term of this
Agreement, the term and the Expiration Date will be automatically extended for
one (1) additional year so that the remaining term on this Agreement will be not
less than four (4) and not more than five (5) years.

6.       Termination. This Agreement will continue in effect until the
expiration of the term set forth in paragraph 5 of this Agreement unless earlier
terminated pursuant to this paragraph 6.

         6.1      Termination by Company. The Company will have the following
                  rights to terminate this Agreement:

                  6.1.1    Termination without Cause.  The Company may terminate
                           this Agreement without cause at any time by the
                           service of written notice of termination to the
                           Executive specifying an effective date of such
                           termination not sooner than sixty (60) business days
                           after the date of such notice (the "Termination
                           Date"). In the event the Executive is terminated
                           without cause (other than a CC Termination under
                           paragraph 6.3 of this Agreement), the Executive will
                           receive as termination compensation: (a) Base
                           Compensation (as hereafter defined) during the
                           remaining term of this Agreement, but in any event
                           through the Expiration Date; (b) any benefits payable
                           by operation of paragraph 4.4 of this Agreement
                           during the remaining term of this Agreement, but in
                           any event through the Expiration Date; and (c) any
                           vacation pay accrued through the Termination Date.
                           For purposes of this Agreement the term "Base
                           Compensation" means the Executive's current Base
                           Salary under paragraph 4.1 on the Termination Date
                           plus the bonus compensation received by the Executive
                           during the twelve (12) month period preceding the
                           Termination Date.

                  6.1.2    Termination for Cause.  The Company may terminate
                           this Agreement for cause if the Executive: (a)
                           misappropriates the property of the Company or
                           commits any other act of dishonesty; (b) engages in
                           personal misconduct which materially injures the
                           Company; (c) willfully violates any law or regulation
                           relating to the business of the Company which results
                           in injury to the Company; or (d) willfully and
                           repeatedly fails to perform the Executive's duties
                           hereunder. In the event this Agreement is terminated
                           for cause, the Company will not have any obligation
                           to provide any further payments or benefits to the
                           Executive after the effective date of such
                           termination. This Agreement will not be deemed to
                           have terminated for cause unless a written
                           determination specifying the reasons for such
                           termination is made, approved by a majority of the
                           disinterested members of the board of directors of
                           the Company and delivered to the Executive.
                           Thereafter, the Executive will have the right for a
                           period of twenty (20) days to request a board of
                           directors meeting to be held at a mutually agreeable
                           time and location within thirty (30) days, at which
                           meeting the Executive will have an opportunity to be
                           heard. Failing such determination and opportunity for
                           hearing, any termination of this Agreement will be
                           deemed to have occurred without cause.

         6.2      Termination by Executive. The Executive may voluntarily
                  terminate this Agreement with or without cause by the service
                  of written notice of such termination to the Company
                  specifying an effective date of such termination sixty (60)
                  days after the date of such notice, during which time
                  Executive may use remaining accrued vacation days, or at the
                  Company's option, be paid for such days. In the event this
                  Agreement is terminated by the Executive, neither the Company
                  nor the Executive will have any further obligations hereunder
                  including, without limitation, any obligation of the Company
                  to provide any further payments or benefits to the Executive
                  after the effective date of such termination.

         6.3      Termination After Change in Control. If during the term of
                  this Agreement there is a "Change of Control" and within two
                  (2) years thereafter there is a CC Termination (as hereafter
                  defined) then the Executive will be entitled to a severance
                  payment (in addition to any other rights and other amounts
                  payable to the Executive under this Agreement or otherwise) in
                  an amount equal to the sum of the following: (a) five (5)
                  times the Executive's Base Compensation; plus (b) the Gross-up
                  Amount (as hereafter defined). If the foregoing amount is not
                  paid within ten (10) days after the CC Termination, the unpaid
                  amount will bear interest at the per annum rate equal to the
                  prime rate published from time to time in the Wall Street
                  Journal. The interest rate will be adjusted on the date of a
                  change in such prime rate. For purposes of this Agreement the
                  term "Gross-up Amount" means the amount of the payment which
                  will result in the Executive retaining from such payment
                  (after paying all taxes imposed on such payment and any
                  interest or penalties related to such taxes) an amount equal
                  to any excise tax imposed by Section 4999 of the Internal
                  Revenue Code of 1986, as amended, together with any


                                       -8-

<PAGE>   12
                  interest and penalties with respect to such excise tax imposed
                  on the all of the payments made to the Executive under this
                  paragraph 6.3.

                  6.3.1    Change of Control.  The term "Change of Control"
                           means any action of a nature that would be required
                           to be reported in response to Item 6(e) of Schedule
                           14A of Regulation 14A under the Securities Exchange
                           Act of 1934 with respect to the Company including,
                           without limitation (i) the direct or indirect
                           acquisition by any person after the date hereof of
                           beneficial ownership of the right to vote or
                           securities of the Company representing the right to
                           vote thirty five percent (35%) or more of the
                           combined voting power of the Company's then
                           outstanding securities having the right to vote for
                           the election of directors, or (ii) within two years
                           of a tender offer or exchange offer for the voting
                           stock of the Company or as a result of a merger,
                           consolidation, sale of assets or contested election
                           (or any combination of the foregoing), a majority of
                           the members of the Company's board of directors is
                           replaced by directors who were not nominated and
                           approved by the board of directors.

                  6.3.2    CC Termination.  The term "CC Termination" means any
                           of the following: (a) this Agreement expires in
                           accordance with its terms; (b) this Agreement is not
                           extended under paragraph 5 of this Agreement and the
                           Executive resigns within one (1) year after such
                           nonextension; (c) the Executive is terminated by the
                           Company other than under paragraphs 6.1.2, 6.4 or 6.5
                           based on adequate grounds; (d) the Executive resigns
                           as a result of a change in the Executive's duties, a
                           reduction in the Executive's then current
                           compensation, a required relocation more than 25
                           miles from the Executive's then current place of
                           employment or a default by the Company under this
                           Agreement; (e) the failure by the Company after a
                           Change of Control to obtain the assumption of this
                           Agreement, without limitation or reduction, by any
                           successor to the Company or any parent corporation of
                           the Company; or (f) after a Change of Control has
                           occurred, the Executive agrees to remain employed by
                           the Company for a period of three (3) months to
                           assist in the transition and thereafter resigns.

         6.4      Incapacity of Executive. If the Executive suffers from a
                  physical or mental condition which in the reasonable judgment
                  of the Company's board of directors prevents the Executive in
                  whole or in part from performing the duties specified herein
                  for a period of three (3) consecutive months, the Executive
                  may be terminated. Although the termination shall be deemed as
                  a termination with cause, any compensation payable under
                  paragraph 4 of this Agreement will be continued through the
                  remaining term of this Agreement, but in any event through the
                  Expiration Date. Notwithstanding the foregoing, the
                  Executive's Base Salary specified in paragraph 4.1 of this
                  Agreement will be reduced by any benefits payable under any
                  disability plans provided by the Company under paragraph 4 of
                  this Agreement.

         6.5      Death of Executive. If the Executive dies during the term of
                  this Agreement, the Company may thereafter terminate this
                  Agreement without compensation to the Executive's estate
                  except: (a) the obligation to continue the Base Salary
                  payments under paragraph 4.1 of this Agreement for twelve (12)
                  months after the effective date of such termination, and (b)
                  the benefits described in paragraph 4.4 of this Agreement
                  accrued through the effective date of such termination.

         6.6      Effect of Termination. The termination of this Agreement will
                  terminate all obligations of the Executive to render services
                  on behalf of the Company, provided that the Executive will
                  maintain the confidentiality of all information acquired by
                  the Executive during the term of his employment in accordance
                  with paragraph 7 of this Agreement. In the event of a
                  termination under paragraphs 6.1.1 or 6.3 of this Agreement
                  the Executive's right to participate in Program Wells will

                  bonus, severance pay or other form of compensation will be
                  payable by the Company to the Executive by reason of the
                  termination of this Agreement. All keys, entry cards, credit

                  and to reassign the Executive's office space after such date.
                  Prior to the effective date of termination, the Executive will
                  render such services to the Company as might be reasonably
                  required to provide for the orderly termination of the
                  Executive's employment.

entitled to a copy of any Confidential Information in the possession of the
Executive. The Executive also agrees that the provisions of this paragraph 7
will survive the termination, expiration or cancellation of this Agreement for a

thereafter), the Executive will assign or execute any and all applications,
assignments and or other instruments and do all things which the Company deems
necessary or appropriate in order to permit the Company to: (a) assign and
convey or otherwise make available to the Company the sole and exclusive right,

know-how. However, the improvements, inventions, discoveries, processes or

10.      Arbitration. The parties will attempt to promptly resolve any dispute
or controversy arising out of or relating to this Agreement or termination of
the Executive by the Company. Any negotiations pursuant to this paragraph 10 are
confidential and will be treated as compromise and settlement negotiations for
all purposes. If the parties are unable to reach a settlement amicably, the
dispute will be submitted to binding arbitration before a single arbitrator in
accordance with the Employment Dispute Resolution Rules of the American
Arbitration Association. The arbitrator will be instructed and empowered to take
reasonable steps to expedite the arbitration and the arbitrator's judgment will
be final and binding upon the parties subject solely to challenge on the grounds
of fraud or gross misconduct. Except for damages arising out of a breach of
paragraphs 6, 7, 8 or 9 of this Agreement, the arbitrator is not empowered to
award total damages (including compensatory damages) which exceed 300% of
compensatory damages and each party hereby irrevocably waives any damages in
excess of that amount. The arbitration will be held in Oklahoma County,
Oklahoma. Judgment upon any verdict in arbitration may be entered in any court
of competent jurisdiction and the parties hereby consent to the jurisdiction of,
and proper venue in, the federal and state courts located in Oklahoma County,
Oklahoma. Each party will bear its own costs in connection with the arbitration
and the costs of the arbitrator will be borne by the party who the arbitrator
determines did not prevail in the matter. Unless otherwise expressly set forth
in this Agreement, the procedures specified in this paragraph 10 will be the
sole and exclusive procedures for the resolution of disputes and controversies
between the parties arising out of or relating to this Agreement.
Notwithstanding the foregoing, a party may seek a preliminary injunction or
other provisional judicial relief if in such party's judgment such action is
necessary to avoid irreparable damage or to preserve the status quo.
