PART I

ITEM 1. BUSINESS

GENERAL

Chesapeake Energy Corporation ("Chesapeake" or the "Company") is an
independent oil and gas company primarily engaged in the exploration,
acquisition, development and production of onshore natural gas reserves in the
United States and Canada. Chesapeake began operations in 1989, completed an
initial public offering in 1993, and trades on the New York Stock Exchange under
the symbol CHK. The Company's principal offices are located at 6100 North
Western Avenue, Oklahoma City, Oklahoma 73118 (telephone 405/848-8000).

Chesapeake currently owns interests in approximately 5,300 producing oil and
gas wells concentrated in three primary operating areas: the Mid-Continent
region consisting of Oklahoma, southwestern Kansas and the Texas Panhandle; the
Gulf Coast region consisting primarily of the Austin Chalk Trend in Texas and
Louisiana and the Tuscaloosa Trend in Louisiana; and the Helmet area of
northeastern British Columbia. During 1998 the Company produced 130.3 Bcfe, of
which 72% was natural gas, making Chesapeake one of the top 20 public
independent oil and gas companies in the United States as measured by
production.

The following table sets forth the Company's estimated proved reserves, the
related present value (discounted at 10%) of the proved reserves (based on
weighted average prices at December 31, 1998 of $10.48 per barrel of oil and
$1.68 per Mcf of gas), and the estimated capital expenditures required to
develop the Company's proved undeveloped reserves at December 31, 1998:

</TABLE>


From inception through mid-1997, Chesapeake's primary business strategy was
growth through the drillbit. In 1997, however, disappointing drilling results in
the Louisiana Austin Chalk Trend, combined with the industry's rapidly
escalating drilling costs and falling oil prices, caused management to change
the Company's business strategy. As a result of this change, in late 1997 and
1998 the Company significantly reduced its capital expenditures for exploration
drilling and acreage acquisition and focused on the acquisition of long-lived
natural gas properties in the Mid-Continent and Canada that contain numerous low
risk development opportunities. During 1998, the Company acquired approximately
750 Bcfe primarily in eight separate transactions. The total consideration given
for the acquisitions was 30.8 million shares of Company common stock, $280
million in cash, the assumption of $205 million in debt, and the incurrence of
approximately $20 million of other acquisition related costs.

The oil and gas industry is characterized by volatile product prices. During
late 1998, inflation-adjusted prices for oil reached lows not seen in 50 years.
Also, a second consecutive mild winter and the resulting high inventory of
natural gas in storage have caused gas prices to fall. These low oil and gas
prices, combined with the Company's high level of indebtedness, have caused the
Company to focus on decreasing operating and general and administrative costs
and reducing drilling capital expenditures to a level that can be financed from
operating cash flow, including proceeds from the sale of non-core, low-value oil
properties. The Company's strategy for 1999 is to maintain appropriate liquidity
levels while concentrating on further developing its core natural gas assets.

MARKETING

The Company's oil production is sold under market sensitive or spot price
contracts. The Company's natural gas production is sold to purchasers under
varying percentage-of-proceeds and percentage-of-index contracts. By the terms
of these contracts, the Company receives a percentage of the resale price
received by the purchaser for sales of residue gas and natural gas liquids
recovered after gathering and processing the Company's gas. The residue gas and
natural gas liquids sold by these purchasers are sold primarily based on spot
market prices. The revenue received by the Company from the sale of natural gas
liquids is included in natural gas sales. During 1998, the following two
customers individually accounted for 10% or more of the Company's total oil and
gas sales:

</TABLE>

Management believes that the loss of either of the above customers would not
have a material adverse effect on the Company's results of operations or its
financial position.

Chesapeake Energy Marketing, Inc. ("CEMI"), a wholly-owned subsidiary,
provides oil and natural gas marketing services, including commodity price
structuring, contract administration and nomination services for the Company,
its partners and other oil and natural gas producers in geographical areas in
which the Company is active.

HEDGING ACTIVITIES

Periodically the Company utilizes hedging strategies to hedge the price of a
portion of its future oil and gas production. These strategies include (i) 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, (ii)
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, (iii) 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
(iv) basis protection swaps, which are arrangements that guarantee the price
differential of oil or gas from a specified delivery point or points. Results
from commodity hedging transactions are reflected in oil and gas sales to the
extent related to the Company's oil and gas production. The Company only enters
into commodity hedging transactions related to the Company's oil and gas
production volumes or CEMI's physical purchase or sale commitments. Gains or
losses on crude oil and natural gas hedging transactions are recognized as price
adjustments in the months of related production.

As of December 31, 1998, the Company had the following natural gas swap
arrangements designed to hedge a portion of the Company's domestic gas
production for periods after December 1998:

</TABLE>

During 1998, the Company closed transactions for natural gas previously
hedged for the period April 1999 through November 1999 for net proceeds of $0.5
million.

Subsequent to December 31, 1998, the Company entered into additional natural
gas swap arrangements for 6,100,000 MMBtu at a strike price of $1.875 for the
period from June 1999 through September 1999. Such swap arrangements, along with
those listed above and other miscellaneous transactions, were closed as of March
15, 1999, resulting in net proceeds of $4.7 million.

As of December 31, 1998, the Company had the following natural gas swap
arrangements designed to hedge a portion of the Company's Canadian gas
production for periods after December 1998:

</TABLE>

If the swap arrangements listed above had been settled on December 31, 1998,
the Company would have incurred a loss of $0.2 million. Subsequent to December
31, 1998, the Company settled the swap arrangements listed above for the periods
of January 1999 and February 1999 resulting in a $0.4 million loss.

In addition to commodity hedging transactions related to the Company's oil
and gas production, CEMI periodically enters into various hedging transactions
designed to hedge against physical purchase and sale commitments made by CEMI.
Gains or losses on these transactions are recorded as adjustments to oil and gas
marketing sales in the consolidated statements of operations and are not
considered by management to be material.

The Company also utilizes hedging strategies to manage fixed-interest rate
exposure. Through the use of a swap arrangement, the Company believes it can
benefit from stable or falling interest rates and reduce its current interest
expense. For the year ended December 31, 1998, the Company's interest rate swap
resulted in a $0.7 million reduction of interest expense.

RISK FACTORS

Substantial Debt Levels Could Affect Operations.

As of December 31, 1998, we had long-term indebtedness of $920 million and
short-term bank indebtedness of $25 million. Additionally, the Company had a
working capital deficit of $13 million and stockholders' equity was a deficit of
$249 million. Our ability to meet our debt service requirements throughout the
life of the senior notes and our ability to meet our preferred stock obligations
will depend on our future performance, which will be subject to oil and gas
prices, our production levels of oil and gas, general economic conditions, and
financial, business and other factors affecting our operations. Our level of
indebtedness may have the following effects on our future operations:

o a substantial portion of our cash flow from operations may be
dedicated to the payment of interest on indebtedness and will
not be available for other purposes,

o restrictions in our debt instruments limit our ability to
borrow additional funds or to dispose of assets and may affect
our flexibility in planning for, and reacting to, changes in
the energy industry, and

o our ability to obtain additional capital in the future may be
impaired.

The short-term indebtedness described above was incurred under our commercial
bank facility which matures in August 1999. Although we believe this facility
will be renewed, we can offer no assurances that we will be able to renew the
bank facility on favorable terms. As a result of our high level of indebtedness
and poor conditions in the energy industry, Standard & Poor's Corporation and
Moody's Investors Service, in late 1998, reduced the credit ratings on our
senior notes to "B" and "B3", respectively. These ratings remain under credit
review with negative implications. Low credit ratings could negatively impact
our ability to access capital markets.

The Volatility of Oil and Gas Prices Creates Uncertainties.

Our revenues, operating results and future rate of growth are highly
dependent on the prices we receive for our oil and gas. Historically, the
markets for oil and gas have been volatile and may continue to be volatile in
the future. Various factors which are beyond our control will affect prices of
oil and gas. These factors include:

o worldwide and domestic supplies of oil and gas,

o the ability of the members of the Organization of Petroleum
Exporting Countries to agree to and maintain oil price and
production controls,

o political instability or armed conflict in oil-producing
regions,

o the price and level of foreign imports,

o the level of consumer demand,

o the price and availability of alternative fuels,

o the availability of pipeline capacity,

o weather conditions, and

o domestic and foreign governmental regulations and taxes.

We are unable to predict the long-term effects of these and other conditions on
the prices of oil and gas. Lower oil and gas prices may reduce the amount of oil
and gas we produce, which may adversely affect our revenues and operating
income. Because our 1999 business strategy is to generally match our capital
expenditures for drilling activities to cash flow from operations, significant
reductions in oil and gas prices may require us to reduce our capital
expenditures. Reducing drilling will make it more difficult for us to replace
the reserves we produce.

We Must Replace Reserves to Sustain Production.

As is customary in the oil and gas exploration and production industry, our
future success depends largely upon our ability to find, develop or acquire
additional oil and gas reserves that are economically recoverable. Unless we
replace the reserves we produce through successful development, exploration or
acquisition, our proved reserves will decline. Approximately 30% by volume, or
22% by value, of our total estimated proved reserves at December 31, 1998 were
undeveloped. By their nature, undeveloped reserves are less certain. Recovery of
such reserves will require significant capital expenditures and successful
drilling operations. We cannot assure that the Company can successfully find and
produce reserves economically in the future.

Significant Capital Expenditures Will be Required to Exploit Reserves.

We have made and intend to make substantial capital expenditures in
connection with the exploration, development and production of our oil and gas
properties. Historically, we have funded our capital expenditures through a
combination of internally generated funds, equity issuances and long-term debt
financing arrangements and sale of non-core assets. From time to time, we have
used short-term bank debt, generally as a working capital facility. Future cash
flows are subject to a number of variables, such as the level of production from
existing wells, prices of oil and gas, and our success in developing and
producing new reserves and in selling non-core assets. If revenue were to
decrease as a result of lower oil and gas prices or decreased production, and
our access to capital were limited, we would have a reduced ability to replace
our reserves. If our cash flow from operations is not sufficient to fund our
capital expenditure budget, there can be no assurance that additional debt or
equity financing will be available to meet these requirements.

We May Have Additional Full-Cost Ceiling Writedowns if Oil and Gas Prices
Decline Further or if Drilling Results are Unfavorable.

The Company reported full-cost ceiling writedowns of $826 million, $110
million, and $236 million during the year ended December 31, 1998, the six month
transition period ended December 31, 1997 (the "Transition Period"), and the
fiscal year ended June 30, 1997, respectively. These writedowns were caused by
significant declines in oil and gas prices during all three periods and by poor
drilling results in 1997 and during the Transition Period. Additionally,
significant declines in prices can cause proved undeveloped reserves to become
uneconomic, and long-lived production to become "economically truncated",
further reducing proved reserves and increasing any writedown. Such economic
truncation resulted in the Company's reserves being approximately 100 Bcfe less
at

December 31, 1998 than they would have been using pricing in effect as of
December 31, 1997. The Company's reserve values were calculated using weighted
average prices at December 31, 1998 of $10.48 per barrel of oil and $1.68 per
Mcf of natural gas. If prices in future periods are below the prices used at
December 31, 1998, future impairment charges will likely be incurred. Although
the Company has taken steps to reduce drilling risk, reduce operating costs, and
reduce investment in unproved leasehold, these steps may not be sufficient to
enhance future economic results or prevent additional leasehold impairment and
full-cost ceiling writedowns, which are highly dependent on future oil and gas
prices.

Drilling and Oil and Gas Operations Present Unique Risks.

Drilling activities are subject to many risks, including well blowouts,
cratering, uncontrollable flows of oil, natural gas or well fluids, fires,
formations with abnormal pressures, pollution, releases of toxic gases and other
environmental hazards and risk, any of which could result in substantial losses.
In addition, we incur the risk that we will not encounter any commercially
productive reservoirs through our drilling operations. We cannot assure you that
the new wells we drill will be productive or that we will recover all or any
portion of our investment in wells drilled. Drilling for oil and gas may involve
unprofitable efforts, not only from dry wells, but from wells that are
productive but do not produce enough reserves to return a profit after drilling,
operating and other costs.

Existing Debt Covenants Restrict Our Operations.

The indentures which govern our long-term debt contain covenants which
restrict our ability, and the ability of our subsidiaries other than CEMI, to
engage in the following activities:

o incurring additional debt,

o creating liens,

o paying dividends and making other restricted payments,

o merging or consolidating with any other entity,

o selling, assigning, transferring, leasing or otherwise
disposing of all or substantially all of our assets, and

o guaranteeing any indebtedness.

At December 31, 1998, the Company did not meet a debt incurrence test
contained in two of the senior note indentures. Thus, we will be unable to incur
unsecured non-bank debt until there is significant improvement in oil and gas
prices and/or our production levels. Additionally, the Company will not be able
to resume the payment of dividends on its common and preferred stock until it
meets the debt incurrence test.

Canadian Operations Present the Risks Associated with Conducting Business
Outside the U.S.

A portion of our business is conducted in Canada. You may review the amounts
of revenue, operating losses and identifiable assets attributable to our
Canadian operations in Note 8 of the Notes to our Consolidated Financial
Statements in Item 8. Also, Note 11 of the Consolidated Financial Statements
provides disclosures about our Canadian oil and gas producing activities. Our
operations in Canada are subject to the risks associated with operating outside
of the United States. These risks include the following:

o adverse local political or economic developments,

o exchange controls,

o currency fluctuations,

o royalty and tax increases,

o retroactive tax claims,

o negotiations of contracts with governmental entities, and

o import and export regulations.

In addition, in the event of a dispute, we may be required to litigate the
dispute in Canadian courts since we may not be able to sue foreign persons in a
United States court.

Pending Legal Proceedings Could Have A Material Adverse Effect.

The Company is a defendant in two purported class actions based on federal
and state securities fraud claims. In addition, we are defending claims of
patent infringement in another pending action. While no prediction can be made
as to the outcome of these matters or the amount of damages that might be
awarded, if any, an adverse result in any of them could be material to our
financial results. See Item 3. Legal Proceedings.

The Loss of Either the CEO or the COO Could Adversely Affect Operations.

Our operations are dependent upon our Chief Executive Officer, Aubrey K.
McClendon, and our Chief Operating Officer, Tom L. Ward. The unexpected loss of
the services of either of these executive officers could have a detrimental
effect on our operations. The Company maintains $20 million key man life
insurance policies on the life of each of Messrs. McClendon and Ward.

Transactions with Executive Officers May Create Conflicts of Interest.

Messrs. McClendon and Ward have rights to participate in wells we drill
during any succeeding quarter, and they participated in every well we have
drilled through December 31, 1998. As a result of their participation, they
routinely have significant accounts payable to the Company for joint interest
billings. As of December 31, 1998, Messrs. McClendon and Ward had payables to
the Company of $2.8 million and $2.4 million, respectively, in connection with
such participation. Additionally, Messrs. McClendon and Ward have loans due on
December 31, 1999 to CEMI in the principal amounts of $4.9 million and $5.0
million (as of December 31, 1998), respectively. Such loans, which were first
made in July 1998, are collateralized and carry an annual interest rate of
9.125%. As of March 30, 1999, Messrs. McClendon and Ward's loans have been
reduced to $4.3 million and $4.6 million, respectively. The existence of these
loans and the rights to participate in wells we drill could present a conflict
of interest with respect to Messrs. McClendon and Ward.

The Ownership of A Significant Percentage of Stock by Insiders Could Influence
the Outcome of Shareholder Votes.

At March 26, 1999, our Board of Directors and senior management beneficially
owned an aggregate of 27,923,997 shares of common stock (including outstanding
vested options), which represented approximately 28% of our outstanding shares.
The ownership of Messrs. McClendon and Ward and their children's trusts
accounted for 25% of the outstanding common stock. As a result, Messrs.
McClendon and Ward, together with other officers and directors of the Company,
are in a position to significantly influence matters requiring the vote or
consent of our shareholders.

The Company Could be Adversely Affected if Our Computer Systems or Those of Our
Vendors Are Not Year 2000 Compliant.

Year 2000 issues exist when dates are recorded in computers using two
digits, rather than four, and are then used for arithmetic operations,
comparisons or sorting. A two-digit recording may recognize a date using "00" as
1900 rather than 2000, which could cause our computer systems to perform
inaccurate computations. Year 2000 issues relate not only to our systems, but
also to those used by our suppliers. We anticipate that system replacements and
modifications will resolve any Year 2000 issues that may exist with our
suppliers or their suppliers. However, we cannot guarantee that such
replacements or modifications will be completed successfully or on time and, as
a result, any failure to complete such modifications on time could materially
affect our financial and operating results in a negative way. Please read the
additional discussion regarding the Year 2000 issue and the potential impact on
our business in the section entitled "Management's Discussion and Analysis of
Financial Condition and Results of Operations - Year 2000" later in this Form
10-K for additional information.

REGULATION

General

Numerous departments and agencies, federal, state and local, issue rules and
regulations binding on the oil and gas industry, some of which carry substantial
penalties for failure to comply. The regulatory burden on the oil and gas
industry increases the Company's cost of doing business and, consequently,
affects its profitability.

Exploration and Production

The Company's operations are subject to various types of regulation at the
federal, state and local levels. Such regulation includes requiring permits for
the drilling of wells, maintaining bonding requirements in order to drill or
operate wells and regulating the location of wells, the method of drilling and
casing wells, the surface use and restoration of properties upon which wells are
drilled, the plugging and abandoning of wells and the disposal of fluids used or
obtained in connection with operations. The Company's operations are also
subject to various conservation regulations. These include the regulation of the
size of drilling and spacing units and the density of wells which may be drilled
and the unitization or pooling of oil and gas properties. In this regard, some
states (such as Oklahoma) allow the forced pooling or integration of tracts to
facilitate exploration while other states (such as Texas) rely on voluntary
pooling of lands and leases. In areas where pooling is voluntary, it may be more
difficult to form units and, therefore, more difficult to develop a prospect if
the operator owns less than 100% of the leasehold. In addition, state
conservation laws establish maximum rates of production from oil and gas wells,
generally prohibit the venting or flaring of gas and impose certain requirements
regarding the ratability of production. The effect of these regulations is to
limit the amount of oil and gas the Company can produce from its wells and to
limit the number of wells or the locations at which the Company can drill. The
extent of any impact on the Company of such restrictions cannot be predicted.

Environmental and Occupational Regulation

General. The Company's activities are subject to existing federal, state and
local laws and regulations governing environmental quality and pollution
control. It is anticipated that, absent the occurrence of an extraordinary
event, compliance with existing federal, state and local laws, rules and
regulations concerning the protection of the environment and human health will
not have a material effect upon the operations, capital expenditures, earnings
or the competitive position of the Company. The Company cannot predict what
effect additional regulation or legislation, enforcement policies thereunder and
claims for damages for injuries to property, employees, other persons and the
environment resulting from the Company's operations could have on its
activities.

Activities of the Company with respect to the exploration, development and
production of oil and natural gas are subject to stringent environmental
regulation by state and federal authorities including the United States
Environmental Protection Agency ("EPA"). Such regulation has increased the cost
of planning, designing, drilling, operating and in some instances, abandoning
wells. In most instances, the regulatory requirements relate to the handling and
disposal of drilling and production waste products and waste created by water
and air pollution control procedures. Although the Company believes that
compliance with environmental regulations will not have a material adverse
effect on operations or earnings, risks of substantial costs and liabilities are
inherent in oil and gas operations, and there can be no assurance that
significant costs and liabilities, including criminal penalties, will not be
incurred. Moreover, it is possible that other developments, such as stricter
environmental laws and regulations, and claims for damages for injuries to
property or persons resulting from the Company's operations could result in
substantial costs and liabilities.

Waste Disposal. The Company currently owns or leases, and has in the past
owned or leased, numerous properties that for many years have been used for the
exploration and production of oil and gas. Although the Company has utilized
operating and disposal practices that were standard in the industry at the time,
hydrocarbons or other wastes may have been disposed of or released on or under
the properties owned or leased by the Company or on or under other locations
where such wastes have been taken for disposal. In addition, many of these
properties have been operated by third parties whose treatment and disposal or
release of hydrocarbons or other wastes was not under the Company's control.
State and federal laws applicable to oil and natural gas wastes and properties
have gradually become more strict. Under such laws, the Company could be
required to remove or remediate previously disposed wastes (including wastes
disposed of or released by prior owners or operators)




10
11

or property contamination (including groundwater contamination) or to perform
remedial plugging operations to prevent future contamination.

The Company generates wastes, including hazardous wastes, that are subject
to the federal Resource Conservation and Recovery Act ("RCRA") and comparable
state statutes. The EPA and various state agencies have limited the disposal
options for certain hazardous and nonhazardous wastes and are considering the
adoption of stricter disposal standards for nonhazardous wastes. Furthermore,
certain wastes generated by the Company's oil and natural gas operations that
are currently exempt from treatment as hazardous wastes may in the future be
designated as hazardous wastes, and therefore be subject to considerably more
rigorous and costly operating and disposal requirements.

Superfund. The Comprehensive Environmental Response, Compensation and
Liability Act ("CERCLA"), also known as the "Superfund" law, imposes liability,
without regard to fault or the legality of the original conduct, on certain
classes of persons with respect to the release of a "hazardous substance" into
the environment. These persons include the owner and operator of a site and
persons that disposed of or arranged for the disposal of the hazardous
substances found at a site. CERCLA also authorizes the EPA and, in some cases,
third parties to take actions in response to threats to the public health or the
environment and to seek to recover from responsible classes of persons the costs
of such action. In the course of its operations, the Company may have generated
and may generate wastes that fall within CERCLA's definition of "hazardous
substances". The Company may also be or have been an owner of sites on which
"hazardous substances" have been released. The Company may be responsible under
CERCLA for all or part of the costs to clean up sites at which such wastes have
been released. To date, however, neither the Company nor, to its knowledge, its
predecessors or successors have been named a potentially responsible party under
CERCLA or similar state superfund laws affecting property owned or leased by the
Company.

Air Emissions. The operations of the Company are subject to local, state and
federal regulations for the control of emissions of air pollution. Legal and
regulatory requirements in this area are increasing, and there can be no
assurance that significant costs and liabilities will not be incurred in the
future as a result of new regulatory developments. In particular, regulations
promulgated under the Clean Air Act Amendments of 1990 may impose additional
compliance requirements that could affect the Company's operations. However, it
is impossible to predict accurately the effect, if any, of the Clean Air Act
Amendments on the Company at this time. The Company may in the future be subject
to civil or administrative enforcement actions for failure to comply strictly
with air regulations or permits. These enforcement actions are generally
resolved by payment of monetary fines and correction of any identified
deficiencies. Alternatively, regulatory agencies could require the Company to
forego construction or operation of certain air emission sources.

OSHA. The Company is subject to the requirements of the federal Occupational
Safety and Health Act ("OSHA") and comparable state statutes. The OSHA hazard
communication standard, the EPA community right-to-know regulations under Title
III of the federal Superfund Amendment and Reauthorization Act and similar state
statutes require the Company to organize information about hazardous materials
used, released or produced in its operations. Certain of this information must
be provided to employees, state and local governmental authorities and local
citizens. The Company is also subject to the requirements and reporting set
forth in OSHA workplace standards. The Company provides safety training and
personal protective equipment to its employees.

OPA and Clean Water Act. Federal regulations require certain owners or
operators of facilities that store or otherwise handle oil, such as the Company,
to prepare and implement spill prevention control plans, countermeasure plans
and facilities response plans relating to the possible discharge of oil into
surface waters. The Oil Pollution Act of 1990 ("OPA") amends certain provisions
of the federal Water Pollution Control Act of 1972, commonly referred to as the
Clean Water Act ("CWA"), and other statutes as they pertain to the prevention of
and response to oil spills into navigable waters. The OPA subjects owners of
facilities to strict joint and several liability for all containment and cleanup
costs and certain other damages arising from a spill, including, but not limited
to, the costs of responding to a release of oil to surface waters. The CWA
provides penalties for any discharges of petroleum product in reportable
quantities and imposes substantial liability for the costs of removing a spill.
State laws for the control of water pollution also provide varying civil and
criminal penalties and liabilities in the case of releases of




11
12

petroleum or its derivatives into surface waters or into the ground. Regulations
are currently being developed under OPA and state laws concerning oil pollution
prevention and other matters that may impose additional regulatory burdens on
the Company. In addition, the CWA and analogous state laws require permits to be
obtained to authorize discharges into surface waters or to construct facilities
in wetland areas. With respect to certain of its operations, the Company is
required to maintain such permits or meet general permit requirements. The EPA
has adopted regulations concerning discharges of storm water runoff. This
program requires covered facilities to obtain individual permits, participate in
a group permit or seek coverage under an EPA general permit. The Company
believes that with respect to existing properties it has obtained, or is
included under, such permits and with respect to future operations it will be
able to obtain, or be included under, such permits, where necessary. Compliance
with such permits is not expected to have a material effect on the Company.

NORM. Oil and gas exploration and production activities have been identified
as generators of concentrations of low-level naturally-occurring radioactive
materials ("NORM"). NORM regulations have recently been adopted in several
states. The Company is unable to estimate the effect of these regulations,
although based upon the Company's preliminary analysis to date, the Company does
not believe that its compliance with such regulations will have a material
adverse effect on its operations or financial condition.

Safe Drinking Water Act. The Company's operations involve the disposal of
produced saltwater and other nonhazardous oilfield wastes by reinjection into
the subsurface. Under the Safe Drinking Water Act ("SDWA"), oil and gas
operators, such as the Company, must obtain a permit for the construction and
operation of underground Class II injection wells. To protect against
contamination of drinking water, periodic mechanical integrity tests are often
required to be performed by the well operator. The Company has obtained such
permits for the Class II wells it operates. The Company also has disposed of
wastes in facilities other than those owned by the Company which are commercial
Class II injection wells.

Toxic Substances Control Act. The Toxic Substances Control Act ("TSCA") was
enacted to control the adverse effects of newly manufactured and existing
chemical substances. Under the TSCA, the EPA has issued specific rules and
regulations governing the use, labeling, maintenance, removal from service and
disposal of PCB items, such as transformers and capacitors used by oil and gas
companies. The Company may own such PCB items but does not believe compliance
with TSCA has or will have a material adverse effect on the Company's operations
or financial condition.

TITLE TO PROPERTIES

Title to properties is subject to royalty, overriding royalty, carried, net
profits, working and other similar interests and contractual arrangements
customary in the oil and gas industry, to liens for current taxes not yet due
and to other encumbrances. As is customary in the industry in the case of
undeveloped properties, only cursory investigation of record title is made at
the time of acquisition. Drilling title opinions are usually prepared before
commencement of drilling operations. From time to time, the Company's title to
oil and gas properties is challenged through legal proceedings. The Company is
routinely involved in litigation involving title to certain of its oil and gas
properties, none of which management believes will be materially adverse to the
Company, individually or in the aggregate.

OPERATING HAZARDS AND INSURANCE

The oil and gas business involves a variety of operating risks, including
the risk of fire, explosions, blow-outs, pipe failure, abnormally pressured
formations and environmental hazards such as oil spills, gas leaks, ruptures or
discharges of toxic gases, the occurrence of any of which could result in
substantial losses to the Company due to injury or loss of life, severe damage
to or destruction of property, natural resources and equipment, pollution or
other environmental damage, clean-up responsibilities, regulatory investigation
and penalties and suspension of operations. The Company's horizontal and Deep
Tuscaloosa drilling activities involve greater risk of mechanical problems than
conventional vertical drilling operations.



12
13

The Company maintains a $50 million oil and gas lease operator policy that
insures the Company against certain sudden and accidental risks associated with
drilling, completing and operating its wells. There can be no assurance that
this insurance will be adequate to cover any losses or exposure to liability.
The Company also carries comprehensive general liability policies and a $60
million umbrella policy. The Company and its subsidiaries carry workers'
compensation insurance in all states in which they operate and a $35 million
employment practice liability policy. While the Company believes these policies
are customary in the industry, they do not provide complete coverage against all
operating risks.

EMPLOYEES

The Company had 481 full-time employees as of December 31, 1998 and reduced
this level to 453 as of March 15, 1999. No employees are represented by
organized labor unions. The Company considers its employee relations to be good.

FACILITIES

The Company owns 13 buildings totaling approximately 86,500 square feet and
nine acres of land in an office complex in Oklahoma City that comprise its
headquarters' offices. The Company also owns field offices in Lindsay, Waynoka
and Weatherford, Oklahoma and leases office space in Garden City, Hays and
Wichita, Kansas; Oklahoma City, Oklahoma; Big Lake, College Station, Fritch and
Navasota, Texas; Lafayette, Louisiana; and in Calgary, Alberta, Canada. The
offices in Garden City, Wichita, College Station and Lafayette have been or will
be closed in the near future and the space sub-leased or terminated.

ITEM 2. PROPERTIES

PRIMARY OPERATING AREAS

The Company's strategy is to focus its acquisition and development efforts
in three areas: (i) the Mid-Continent (consisting of Oklahoma, southwestern
Kansas and the Texas Panhandle), (ii) the onshore Gulf Coast in Texas and
Louisiana, and (iii) the Helmet area in northeastern British Columbia. In
addition, the Company will selectively pursue exploration projects such as the
Deep Tuscaloosa in Louisiana and the Deep Wilcox in Wharton County, Texas.

Mid-Continent Region. The Company's Mid-Continent proved reserves of 625
Bcfe represented 57% of the Company's total proved reserves as of December 31,
1998 and this area produced 64 Bcfe, or 49% of the Company's 1998 production.

During 1998, the Company invested approximately $63 million to drill 165
gross (96.1 net) wells in the Mid-Continent. The Company has budgeted
approximately $50 million for the Mid-Continent during 1999, representing
approximately 56% of the Company's total budget for exploration and development
activities during the year. The Company anticipates the Mid-Continent will
contribute approximately 67 Bcfe of production during 1999, or 54% of expected
total production.

Gulf Coast. The Company's Gulf Coast proved reserves, consisting of the
Austin Chalk Trend in Texas and Louisiana and the Tuscaloosa Trend in Louisiana,
represented 151 Bcfe or 14% of the Company's total proved reserves as of
December 31, 1998. During 1998, the Gulf Coast assets produced 52 Bcfe, or 40%
of the Company's total production. The Company anticipates the Gulf Coast will
contribute approximately 38 Bcfe of production during 1999, or 31% of expected
total production.

During 1998, the Company invested approximately $109 million to drill 37
gross (17.8 net) wells in the Gulf Coast. For 1999, the Company has budgeted
approximately $6 million for Texas Austin Chalk and Louisiana Austin Chalk
drilling and $15 million for Tuscaloosa exploratory drilling activities. In the
aggregate, these Gulf Coast expenditures represent approximately 23% of the
Company's total budget for exploration and development activities in 1999.

Helmet Area. During fiscal 1996 and 1997, the Company began to evaluate the
possibility of developing a third core area of operations to complement its
activities in the Mid-Continent and Gulf Coast regions. Management believed that
the North American gas market would significantly tighten and as a result,
Canadian natural gas prices, which have significantly lagged U.S. natural gas
prices during the past 15 years, would increase in the future compared to U.S.
gas prices. During 1998, the Company entered into two transactions which
established a significant presence in a major gas field in northeastern British
Columbia.

The Company's Canadian proved reserves of 232 Bcfe represented 21% of the
Company's total proved reserves at December 31, 1998. During 1998, production
from Canada was 8 Bcfe, or 6% of the Company's total production. The Company has
budgeted $15 million to drill seven net wells in 1999 and expects production of
20 Bcfe, or 16% of the Company's estimated total production for 1999.

OTHER OPERATING AREAS

Permian Basin. In 1995 the Company initiated drilling activity in the
Permian Basin in the Lovington area of Lea County, New Mexico. In this project,
the Company is utilizing 3-D seismic technology to search for prospects that
management believes have been overlooked in this portion of the Permian Basin
because of inconclusive results provided by traditional 2-D seismic technology.
During 1998, the Company drilled seven wells in the Lovington area, four of
which were successfully completed and three were unsuccessful. The Company has
budgeted approximately $0.8 million to drill one gross (0.8 net) well in this
area during 1999.




16
17

Wharton County, Texas. In 1997, the Company acquired approximately 25,000
net acres in Wharton County, Texas. This exploration project is seeking gas
production from the shallower Frio and Yegua sands and from the Deep Wilcox at
depths of up to 19,000 feet. The Company participated with a 55% interest in a
85,000 acre 3-D seismic program with Coastal Oil & Gas Corporation, Seagull
Energy Corporation and other industry partners during 1998 to delineate
potential future drillsites in the prospect. During 1998, the Company drilled
its first well in the prospect, which was abandoned as a dry hole.

Williston Basin. In 1996, the Company began acquiring leasehold in the
Williston Basin, located in eastern Montana and western North Dakota, and as of
December 31, 1998 owned approximately 0.9 million gross (0.6 million net) acres.
During the Transition Period, the Company drilled and successfully completed six
wells targeting the Red River formation on the northern portion of its
leasehold. During 1998, the Company invested approximately $4.2 million to drill
three gross (2.8 net) wells in the Williston Basin. The Company does not plan to
drill any wells during 1999 in the Williston Basin unless oil prices increase
significantly.

OIL AND GAS RESERVES

The tables below set forth information as of December 31, 1998 with respect
to the Company's estimated net proved reserves, the estimated future net revenue
therefrom and the present value thereof at such date. Williamson Petroleum
Consultants, Inc., Ryder Scott Company Petroleum Engineers and H.J. Gruy and
Associates, Inc. evaluated 63%, 12% and 1%, respectively, of the Company's
combined discounted future net revenues from the Company's estimated proved
reserves at December 31, 1998. The remaining properties were evaluated
internally by the Company's engineers. All estimates were prepared based upon a
review of production histories and other geologic, economic, ownership and
engineering data developed by the Company. The present value of estimated future
net revenue shown is not intended to represent the current market value of the
estimated oil and gas reserves owned by the Company.

- ----------

(a) Estimated future net revenue represents estimated future gross revenue
to be generated from the production of proved reserves, net of
estimated production and future development costs, using prices and
costs in effect at December 31, 1998. The amounts shown do not give
effect to non-property related expenses, such as general and
administrative expenses, debt service and future income tax expense or
to depreciation, depletion and amortization. The prices used in the
external and internal reports yield weighted average prices of $10.48
per barrel of oil and $1.68 per Mcf of gas.


The future net revenue attributable to the Company's estimated proved
undeveloped reserves of $345 million at December 31, 1998, and the $147 million
present value thereof, have been calculated assuming that the Company will
expend approximately $144 million to develop these reserves. The amount and
timing of these expenditures will depend on a number of factors, including
actual drilling results, product prices and the availability of capital.

No estimates of proved reserves comparable to those included herein have
been included in reports to any federal agency other than the Securities and
Exchange Commission.

The Company's interest used in calculating proved reserves and the estimated
future net revenue therefrom was determined after giving effect to the assumed





17
18

maximum participation by other parties to the Company's farmout and
participation agreements. The prices used in calculating the estimated future
net revenue attributable to proved reserves do not reflect market prices for oil
and gas production sold subsequent to December 31, 1998. There can be no
assurance that all of the estimated proved reserves will be produced and sold at
the assumed prices or that existing contracts will be honored or judicially
enforced.

There are numerous uncertainties inherent in estimating quantities of proved
reserves and in projecting future rates of production and timing of development
expenditures, including many factors beyond the control of the Company. The
reserve data set forth herein represent only estimates. Reserve engineering is a
subjective process of estimating underground accumulations of oil and gas that
cannot be measured in an exact way, and the accuracy of any reserve estimate is
a function of the quality of available data and of engineering and geological
interpretation and judgment. As a result, estimates made by different engineers
often vary. In addition, results of drilling, testing and production subsequent
to the date of an estimate may justify revision of such estimates, and such
revisions may be material. Accordingly, reserve estimates are often different
from the actual quantities of oil and gas that are ultimately recovered.
Furthermore, the estimated future net revenue from proved reserves and the
present value thereof are based upon certain assumptions, including prices,
future production levels and cost, that may not prove correct. Predictions about
prices and future production levels are subject to great uncertainty, and the
foregoing uncertainties are particularly true as to proved undeveloped reserves,
which are inherently less certain than proved developed reserves and which
comprise a significant portion of the Company's proved reserves.

See Item 1 and Note 11 of Notes to Consolidated Financial Statements
included in Item 8 for a description of the Company's primary and other
operating areas, production and other information regarding its oil and gas
properties.

ITEM 3. LEGAL PROCEEDINGS

The Company is subject to ordinary routine litigation incidental to its
business. In addition, the following matters are pending:

Securities Litigation. On January 13, 1998, a consolidated class action
complaint styled In re Chesapeake Energy Corporation Securities Litigation was
filed in the U.S. District Court for the Western District of Oklahoma. It
consolidated 12 pending purported class actions filed in August and September
1997. The action is brought on behalf of purchasers of the Company's common
stock and common stock options between January 25, 1996 and June 27, 1997. The
defendants are the Company and the following officers and directors: Aubrey K.
McClendon, Tom L. Ward, Marcus C. Rowland, Shannon T. Self, Walter C. Wilson,
Henry J. Hood, Steven C. Dixon, J. Mark Lester and Ronald A. Lefaive. The
complaint alleges violations of Sections 10(b) and 20(a) of the Securities
Exchange Act of 1934 and Rule 10b-5 thereunder.

The plaintiffs assert that the defendants made material
misrepresentations and failed to disclose material facts about the success of
the Company's exploration and drilling activities in the Louisiana Trend. The
complaint alleges the lack of disclosure artificially inflated the price of the
Company's common stock during the period beginning January 25, 1996 and ending
on 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
the Company's 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 on
March 16, 1998 filed a motion to dismiss. To date, the U.S. District Court has
not ruled on this motion. No estimate of loss or range of estimate of loss, if
any, can be made at this time.

Bayard Drilling Technologies, Inc. ("Bayard"). On July 30, 1998, the
plaintiffs in Yuan, et al. v. Bayard, et al. filed an Amended Class Action
Complaint in the U.S. District Court for the Western District of Oklahoma
alleging violations of Sections 11 and 12 of the Securities Act of 1933 and
Section 408 of the Oklahoma Securities Act by the Company and others. The action
was brought purportedly on behalf of investors who purchased Bayard common stock
in, or traceable to, Bayard's initial public offering in November 1997. The
defendants include officers and directors of Bayard who signed the registration
statement, selling shareholders (including the Company) and underwriters of the





18
19

offering. Total proceeds of the offering were $254 million, of which the Company
received net proceeds of $90 million.

In May 1998, two additional purported class actions filed in January
and February 1998 in the District Court for Oklahoma County, Oklahoma were
dismissed without prejudice pursuant to stipulation of all parties. On May 12,
1998, the plaintiffs in the dismissed cases became co-lead plaintiffs in Yuan v.
Bayard, et al.

Plaintiffs allege that the Company, which owned 30.1% of Bayard's
outstanding common stock prior to the offering, was a controlling person of
Bayard. Plaintiffs also allege that the Company had established an interlocking
financial relationship with Bayard and was a customer of Bayard's drilling
services under allegedly below-market terms. Plaintiffs also note the fact that
Messrs. McClendon, Ward and Rowland, executive officers and directors of the
Company, were formerly directors 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 the claims
against it in this action are without merit. On September 11, 1998, the Company
and the other named defendants filed a motion to dismiss. No estimate of loss or
range of estimate of loss, if any, can be made at this time. Bayard has
subsequently agreed to merge into a wholly-owned, newly created, special purpose
subsidiary of Nabors Industries, Inc.

UPRC Patent Suit. On October 15, 1996, Union Pacific Resources Company
("UPRC") filed suit against the Company in the U.S. District Court for the
Northern District of Texas, Fort Worth Division, alleging (i) infringement and
inducing infringement of UPRC's claims to a patent for an invention involving a
method of maintaining a borehole in a stratigraphic zone during drilling, (ii)
tortious interference with contracts between UPRC and certain of its former
employees regarding the confidentiality of proprietary information of UPRC and
(iii) misappropriation of such proprietary information. On May 20, 1998, two
orders were entered granting the Company summary judgment on several issues. The
court ruled as a matter of law that UPRC's tort claims for misappropriation of
trade secrets and tortious interference with business relations are barred by
the statute of limitations. Further, the court found that UPRC's claim for
inducement to infringe its patent for a drillbit steering method is barred as to
any wells drilled by the Company prior to August 14, 1995. The only issues
remaining in the case involve the validity, potential infringement and value, if
any, of UPRC's patent.

UPRC's claims against the Company in UPRC v. Chesapeake Energy
Corporation, et al. 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, enhanced,
consequential and punitive damages, interest, costs and attorneys' fees. The
Company believes that it has meritorious defenses to UPRC's allegations and has
petitioned the court to declare the UPRC patent invalid. Various motions for
summary judgment filed by both parties are pending. While no prediction can be
made as to the outcome of the matter or the amount of damages that might be
awarded, if any, damage estimates have been made in reports of experts 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 the expert's view of a reasonable royalty for use of the
patent. The case has been set for trial in June 1999 on the issue of liability.

At March 26, 1999 there were 1,025 holders of record of common stock and
approximately 28,000 beneficial owners.

DIVIDENDS

The Company paid quarterly dividends of $0.02 per common share from July
1997 to July 1998. In September 1998 the Board of Directors determined that
because of low oil and natural gas prices the payment of cash dividends on the
common stock should be cancelled. The payment of future cash dividends, if any,
will be reviewed periodically by the Board of Directors and will depend upon,
among other things, the Company's financial condition, funds from operations,
the level of its capital and development expenditures, its future business
prospects and any contractual restrictions.

Two of the indentures governing the Company's outstanding senior notes
contain restrictions on the Company's ability to declare and pay dividends.
Under these indentures, the Company may not pay any cash dividends on its common
or preferred stock if (i) a default or an event of default has occurred and is
continuing at the time of or immediately after giving effect to the dividend
payment, (ii) the Company would not be able to incur at least $1 of additional
indebtedness under the terms of the indentures, or (iii) immediately after
giving effect to the dividend payment, the aggregate of all dividends and other
restricted payments declared or made after the respective issue dates of the
notes exceeds the sum of specified income, proceeds from the issuance of stock
and debt by the Company and other amounts from the quarter in which the
respective note issuances occurred to the quarter immediately preceding the date
of the dividend payment. As of December 31, 1998, the Company did not meet the
debt incurrence or the restricted payment tests under these indentures.

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

OVERVIEW

Although the Company's oil and gas revenues, production, and proved reserves
reached record levels during the year ended December 31, 1998 (the "Current
Year"), significant declines in oil and gas prices as of December 31, 1998
resulted in downward revisions in estimates of the Company's proved oil and gas
reserves and the related present value of the estimated future net revenues from
its proved reserves. The Company recorded an $826 million oil and gas property
writedown and a net loss of $934 million during the Current Year.

In response to disappointing drilling results in Louisiana and changes
occurring in oil and natural gas markets, the Company significantly revised its
business strategy during the six months ended December 31, 1997 (the "Transition
Period"). These revisions included (i) reducing the size and risk of its
exploratory drilling program, especially in the Louisiana Trend, (ii) acquiring
significant volumes of long-lived natural gas reserves, particularly in the
Mid-Continent region of the U.S., and (iii) building a larger inventory of lower
risk drilling opportunities through acquisitions and joint ventures. Further,
the Company reduced its capital expenditure budget for exploration and
development to more closely match anticipated cash flow from operations.

As part of this revised strategy, the Company acquired various proved oil
and gas reserves through merger or through purchases of oil and gas properties.
During the Current Year, the Company acquired approximately 750 Bcfe of proved
reserves primarily in eight major transactions. Of these transactions, three
were closed in the first quarter of 1998, and five were closed during the second
quarter of 1998. These acquisitions increased oil and gas production volumes and
revenues, decreased DD&A per Mcfe, and increased production expenses during the
Current Year. Long-term debt and interest expense also increased as a result of
the financing required to fund these acquisitions. The total consideration given
for the acquisitions was 30.8 million shares of Company common stock, $280
million of cash, the assumption of $205 million of debt, and the incurrence of
approximately $20 million of other acquisition related costs.

The Company incurred an $826 million impairment of oil and gas properties in
the Current Year. The writedown was caused by a combination of several factors,
including the acquisitions completed by the Company during the Current Year,
which were accounted for using the purchase method, and the significant
decreases in oil and gas prices throughout the Current Year. Oil and gas prices
used to value the Company's proved reserves decreased from $17.62 per Bbl of oil
and $2.29 per Mcf of gas at December 31, 1997, to $10.48 per Bbl of oil and
$1.68 per Mcf of gas at December 31, 1998. Higher drilling and completion costs
and the evaluation of certain leasehold, seismic and other exploration-related
costs that were previously unevaluated were the remaining contributing factors
which led to the writedown in the Current Year.

During the Current Year, the Company participated in 242 gross (135.2 net)
wells, 156 of which were Company operated. A summary of the Company's drilling
activities and capital expenditures by primary operating area is as follows ($
in thousands):

</TABLE>

The Company's proved reserves increased 144% to an estimated 1,091 Bcfe at
December 31, 1998, an increase of 643 Bcfe from the 448 Bcfe of estimated proved
reserves at December 31, 1997 (see Note 11 of Notes to Consolidated Financial
Statements in Item 8).

24

The Company's strategy for 1999 is to continue developing its natural gas
assets by drilling, but at a significantly reduced pace. The Company has reduced
its capital expenditure budget (before any acquisitions) to approximately $90
million and has reduced the Gulf Coast drilling component significantly.
Furthermore, the Company has increased its use of 3-D seismic to assist in
reducing exploratory risks and increasing economic returns from its drilling
programs. The Company has conducted, participated in, or is actively pursuing
more than 25 3-D seismic programs to evaluate the Company's acreage inventory.

RESULTS OF OPERATIONS

Year Ended December 31, 1998 and 1997

General. In the Current Year, the Company realized a net loss of $933.9
million, or a loss of $9.97 per common share, on total revenues of $381.9
million. This compares to a net loss of $233.4 million, or a loss of $3.30 per
common share, on total revenues of $390.5 million during the year ended December
31, 1997 (the "Prior Year"). The loss in the Current Year was caused primarily
by an $826.0 million oil and gas property writedown recorded under the full-cost
method of accounting and a $55.0 million writedown of other assets. See
"Impairment of Oil and Gas Properties" and "Impairment of Other Assets".

Oil and Gas Sales. During the Current Year, oil and gas sales increased 29%
to $256.9 million versus $198.4 million for the Prior Year. The increase in oil
and gas sales resulted primarily from growth in production volumes. For the
Current Year, the Company produced 130.3 Bcfe at a weighted average price of
$1.97 per Mcfe, compared to 80.3 Bcfe produced in the Prior Year at a weighted
average price of $2.47 per Mcfe.

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

Natural gas production represented approximately 72% of the Company's total
production volume on an equivalent basis in the Current Year, compared to 74% in
the Prior Year. This decrease in gas production as a percentage of total
production was primarily the result of new production in the Louisiana Trend,
which tends to produce more oil than gas. In 1999, the Company's production is
estimated to be approximately 80% gas.

For the Current Year, the Company realized an average price per barrel of
oil of $12.70, compared to $19.39 in the Prior Year. Gas price realizations
decreased from $2.20 per Mcf in the Prior Year to $1.92 per Mcf in the Current
Year. The Company's hedging activities resulted in an increase in oil and gas
revenues of $11.8 million in the Current Year and a decrease in oil and gas
revenues of $4.6 million in the Prior Year.

Oil and Gas Marketing Sales. The Company realized $121.1 million in oil and
gas marketing sales for third parties in the Current Year, with corresponding
oil and gas marketing expenses of $119.0 million, for a net margin of $2.1
million. This compares to sales of $104.4 million, expenses of $103.8 million,
and a margin of $0.6 million in the Prior Year.

Production Expenses and Taxes. Production expenses and taxes, which include
lifting costs, production taxes and ad valorem taxes, increased to $59.5 million
in the Current Year, compared to $19.3 million in the Prior Year. These
increases were primarily the result of increased production and increased
operating costs. On a unit of production basis, production expenses and taxes
increased to $0.45 per Mcfe compared to $0.24 per Mcfe in the Prior Year due
primarily to the higher per unit operating costs associated with many of the oil
and gas properties acquired during the Current Year. The Company expects that
production expenses per Mcfe will generally remain the same in 1999.

Impairment of Oil and Gas Properties. The Company utilizes the full-cost
method to account for its investment 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, along with 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. The excess
of capitalized costs of oil and gas properties, net of accumulated depreciation,
depletion and amortization and related deferred income taxes, over the
discounted future net revenues of proved oil and gas properties is charged to
operations.

The Company incurred an impairment of oil and gas properties charge of $826
million in the Current Year. The writedown was caused by a combination of
several factors, including the acquisitions completed by the Company during the
Current Year, which were accounted for using the purchase method, and the
significant decreases in oil and gas prices throughout the Current Year. Oil and
gas prices used to value the Company's proved reserves decreased from $17.62 per
Bbl of oil and $2.29 per Mcf of gas at December 31, 1997, to $10.48 per Bbl of
oil and $1.68 per Mcf of gas at December 31, 1998. Higher drilling and
completion costs and the evaluation of certain leasehold, seismic and other
exploration-related costs that were previously unevaluated were the remaining
factors which contributed to the writedown in the Current Year.

Impairment of Other Assets. The Company incurred a $55 million impairment
charge during the Current Year. Of this amount, $30 million relates to the
Company's investment in preferred stock of Gothic Energy Corporation, and the
remainder was related to certain of the Company's gas processing and
transportation assets located in Louisiana. No such charge was recorded in the
Prior Year.

Oil and Gas Depreciation, Depletion and Amortization. Depreciation,
depletion and amortization ("DD&A") of oil and gas properties for the Current
Year was $146.6 million, $19.2 million higher than the Prior Year's expense of
$127.4 million. The average DD&A rate per Mcfe, which is a function of
capitalized costs, future development costs, and the related underlying reserves
in the periods presented, decreased to $1.13 in the Current Year ($1.17 in




25
26

U.S. and $0.43 in Canada) compared to $1.59 in the Prior Year. The Company
expects the 1999 DD&A rate to be approximately $0.75 per Mcfe.

Depreciation and Amortization of Other Assets. Depreciation and amortization
("D&A") of other assets increased to $8.1 million in the Current Year, compared
to $4.4 million in the Prior Year. This increase was caused by increased
investments in depreciable buildings and equipment and increased amortization of
debt issuance costs as a result of the issuance of senior notes in April 1998.

General and Administrative. General and administrative ("G&A") expenses,
which are net of capitalized internal payroll and non-payroll expenses (see Note
11 of Notes to Consolidated Financial Statements), were $19.9 million in the
Current Year, up 83% from $10.9 million in the Prior Year. The increase in the
Current Year compared to the Prior Year is due primarily to increased personnel
expenses required by the Company's growth and industry wage inflation. The
Company capitalized $5.3 million and $5.3 million of internal costs in the
Current Year and Prior Year, respectively, directly related to the Company's oil
and gas exploration and development efforts. The Company anticipates that G&A
costs for 1999 will decline as a result of reduced staffing levels.

Interest and Other Income. Interest and other income for the Current Year
were $3.9 million compared to $87.7 million in the Prior Year. During the Prior
Year, the Company realized a gain on the sale of its Bayard common stock of
$73.8 million, the most significant component of interest and other income.

Interest Expense. Interest expense increased to $68.2 million in the Current
Year, compared to $29.8 million in the Prior Year. The increase was due
primarily to the issuance of $500 million of senior notes in April 1998. In
addition to the interest expense reported, the Company capitalized $6.5 million
of interest during the Current Year, compared to $10.4 million capitalized in
the Prior Year. The Company anticipates that capitalized interest for 1999 will
decrease to between $2 million and $3 million.

Provision (Benefit) for Income Taxes. The Company recorded no income taxes
in the Current Year compared to an income tax benefit of $17.9 million in the
Prior Year, before consideration of the $3.7 million tax benefit associated with
an extraordinary loss from the early extinguishment of debt.

At December 31, 1998, the Company had U.S. and Canadian net operating loss
carryforwards of approximately $571 million and $1 million, respectively, 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 of $459 million has been recorded. No deferred
tax benefit related to the exercise of employee stock options was allocated to
additional paid-in capital in the Current Year. The Company does not expect to
record any net income tax expense in 1999 based on information available at this
time.

Six Months Ended December 31, 1997 and 1996

General. For the Transition Period, the Company realized a net loss of $31.6
million, or $0.45 per common share, on total revenues of $232.9 million. This
compares to net income of $18.5 million, or $0.28 per common share, on total
revenues of $122.7 million in the six months ended December 31, 1996 (the "Prior
Period"). The loss in the Transition Period was caused by a $110.0 million asset
writedown recorded under the full-cost method of accounting, partially offset by
a gain of $73.8 million from the sale of Bayard stock. See "Impairment of Oil
and Gas Properties".

Oil and Gas Sales. During the Transition Period, oil and gas sales increased
6% to $95.7 million versus $90.2 million for the Prior Period. The increase in
oil and gas sales resulted primarily from growth in production volumes. For the
Transition Period, the Company produced 38.5 Bcfe at a weighted average price of
$2.49 per Mcfe, compared to 36.8 Bcfe produced in the Prior Period at a weighted
average price of $2.45 per Mcfe.

</TABLE>


Natural gas production represented approximately 71% of the Company's total
production volume on an equivalent basis in the Transition Period, compared to
82% in the Prior Period. This decrease in gas production as a percentage of
total production was primarily the result of new production in the Louisiana
Trend, which tends to produce more oil than gas.

For the Transition Period, the Company realized an average price per barrel
of oil of $18.59, compared to $21.88 in the Prior Period. Gas price realizations
increased slightly from $2.18 per Mcf in the Prior Period to $2.24 per Mcf in
the Transition Period. The Company's hedging activities resulted in decreases in
oil and gas revenues of $4.3 million and $7.1 million in the Transition Period
and Prior Period, respectively.

Oil and Gas Marketing Sales. The Company realized $58.2 million in oil and
gas marketing sales for third parties in the Transition Period, with
corresponding oil and gas marketing expenses of $58.2 million. This compares to
sales of $30.0 million, expenses of $29.5 million, and a margin of $0.5 million
in the Prior Period.

Production Expenses and Taxes. Production expenses and taxes, which include
lifting costs, production taxes and excise taxes, increased to $10.1 million in
the Transition Period, compared to $5.9 million in the Prior Period. These
increases were primarily the result of increased operating costs and increased
production. On a unit of production basis, production expenses and taxes
increased to $0.27 per Mcfe compared to $0.16 per Mcfe in the Prior Period.

Impairment of Oil and Gas Properties. The Company incurred an impairment of
oil and gas properties charge of $110.0 million for the Transition Period. This
writedown was caused by several factors, including oil prices declining from
$18.38 at June 30, 1997 to $17.62 at December 31, 1997, and drilling and
completion costs continuing to escalate during the Transition Period. Higher
costs caused the Company's capital spending to exceed budgeted amounts during
the Transition Period and also increased the estimated future capital
expenditures to be incurred to develop the Company's proved undeveloped
reserves. The Company's results from wells completed during the Transition
Period in the Louisiana Trend continued to be inconsistent and production
performance from various properties in the Navasota River and Independence areas
were lower than projected at June 30, 1997. As a result of the above factors,
the Company recorded a downward revision to its proved reserves of 38 net Bcfe
in the Austin Chalk Trend as of December 31, 1997.

Excluding the purchase of additional leasehold, the Company incurred
approximately $85 million in capital expenditures in the Louisiana Trend during
the Transition Period, of which approximately $67 million were incurred in the
Masters Creek area. Approximately $16 million of the drilling costs were
incurred on Company operated wells that had not been completed at December 31,
1997.

In the Masters Creek area, the Company completed operations on 11 wells
during the Transition Period. Although 10 of the 11 wells were commercially
productive, the drilling costs incurred through December 31, 1997 of
approximately $58 million for the 10 wells were higher than anticipated and
assigned reserves were lower than expected. The lower reserve quantities were
due in part to lower oil prices at December 31, 1997. In addition, the Company
transferred approximately $11 million of previously unevaluated leasehold costs
from all areas of the Louisiana Trend to the amortization base of the full-cost
pool during the Transition Period.

In connection with the Company's acquisition of AnSon Production Corporation
("AnSon") in December 1997, which was accounted for using the purchase method,
the purchase price of approximately $43 million was allocated




27
28
to the fair value of assets acquired. Based upon reserve estimates as of
December 31, 1997, the portion of the purchase price which was allocated to
evaluated oil and gas properties exceeded the associated discounted future net
revenues from AnSon's estimated proved reserves by approximately $14 million.

Oil and Gas Depreciation, Depletion and Amortization. DD&A of oil and gas
properties for the Transition Period was $60.4 million, $24.2 million higher
than the Prior Period's expense of $36.2 million. The expense in the Transition
Period was computed prior to the writedown from the impairment of oil and gas
properties charge. The average DD&A rate per Mcfe increased to $1.57 in the
Transition Period compared to $0.99 in the Prior Period.

Depreciation and Amortization of Other Assets. D&A of other assets increased
to $2.4 million in the Transition Period, compared to $1.8 million in the Prior
Period. This increase was caused by increased investments in depreciable
buildings and equipment and increased amortization of debt issuance costs as a
result of the issuance of senior notes in March 1997.

General and Administrative. G&A expenses, which are net of capitalized
internal payroll and non-payroll expenses (see Note 11 of Notes to Consolidated
Financial Statements), were $5.8 million in the Transition Period, up 56% from
$3.7 million in the Prior Period. The increase in the Transition Period compared
to the Prior Period results primarily from increased personnel expenses required
by the Company's growth and industry wage inflation. The Company capitalized
$2.4 million of internal costs in the Transition Period directly related to the
Company's oil and gas exploration and development efforts, compared to $1.1
million in the Prior Period.

Interest and Other Income. Interest and other income for the Transition
Period was $79.0 million compared to $2.5 million in the Prior Period. During
the Transition Period, the Company realized a gain on the sale of its Bayard
common stock of $73.8 million, the most significant component of interest and
other income.

Interest Expense. Interest expense increased to $17.4 million in the
Transition Period, compared to $6.2 million in the Prior Period. The increase
was due primarily to the issuance of $300 million of senior notes in March 1997.
In addition to the interest expense reported, the Company capitalized $5.1
million of interest during the Transition Period, compared to $7.6 million
capitalized in the Prior Period.

Provision (Benefit) for Income Taxes. The Company recorded no income taxes
for the Transition Period, compared to income tax expense of $14.3 million in
the Prior Period, before consideration of the $3.7 million tax benefit
associated with an extraordinary loss from the early extinguishment of debt.

At December 31, 1997, the Company had a net operating loss carryforward of
approximately $337 million for regular federal income taxes which will expire in
future years beginning in 2007. Management believed that it could not be
demonstrated at that time that it was more likely than not that the deferred
income tax assets, comprised primarily of the net operating loss carryforward,
would be realizable in future years, and therefore a valuation allowance of
$77.9 million was recorded. No deferred tax benefit related to the exercise of
employee stock options was allocated to additional paid-in capital in the
Transition Period.

Fiscal Years Ended June 30, 1997 and 1996

General. For the fiscal year ended June 30, 1997, the Company realized a net
loss of $183.4 million, or $2.79 per common share, on total revenues of $280.3
million. This compares to net income of $23.4 million, or $0.40 per common
share, on total revenues of $149.4 million in 1996. The loss in fiscal 1997
resulted from a $236 million asset writedown recorded in the fourth quarter
under the full-cost method of accounting. See "Impairment of Oil and Gas
Properties".

Oil and Gas Sales. During fiscal 1997, oil and gas sales increased 74% to
$192.9 million versus $110.8 million for fiscal 1996. The increase in oil and
gas sales resulted primarily from strong growth in production volumes and
significantly higher average oil and gas prices. For fiscal 1997, the Company
produced 78.6 Bcfe at a weighted average price of $2.45 per Mcfe, compared to
60.2 Bcfe produced in fiscal 1996 at a weighted average price of $1.84 per Mcfe.
This represents production growth of 31% for fiscal 1997 compared to fiscal
1996.

Natural gas production represented approximately 79% of the Company's total
production volume on an equivalent basis in fiscal 1997. This compares to 86% in
fiscal 1996 and 79% in fiscal 1995. This decrease in gas production as a
percentage of total production in fiscal 1997 was the result of drilling in the
Louisiana Trend, which tends to produce more oil than gas.

For fiscal 1997, the Company realized an average price per barrel of oil of
$20.93, compared to $17.85 in fiscal 1996. The Company markets its oil on
monthly average equivalent spot price contracts and typically receives a premium
to the price posted for West Texas Intermediate crude oil.

Gas price realizations increased from fiscal 1996 to 1997 from $1.66 per Mcf
to $2.18 per Mcf, or 31%, generally as the result of market conditions. The
Company's gas price realizations in fiscal 1997 were also higher due to the
increase in Louisiana Trend gas production, which generally receives premium
prices at least equivalent to Henry Hub indexes due to the high Btu content and
favorable market location of the production.

The Company's hedging activities resulted in decreases in oil and gas
revenues of $7.4 million and $5.9 million in fiscal 1997 and 1996, respectively.

Oil and Gas Marketing Sales. In December 1995, the Company entered into the
oil and gas marketing business by acquiring a subsidiary to provide natural gas
marketing services, including commodity price structuring, contract
administration and nomination services, for the Company, its partners and other
oil and natural gas producers in geographical areas in which the Company is
active. The Company realized $76.2 million in oil and gas marketing sales for
third parties in fiscal 1997, with corresponding oil and gas marketing expenses
of $75.1 million, resulting in a gross margin of $1.1 million. This compares to
sales of $28.4 million, expenses of $27.5 million, and a margin of $0.9 million
in fiscal 1996.

Oil and Gas Service Operations. On June 30, 1996, Peak USA Energy Services,
Ltd., a limited partnership ("Peak"), was formed by Peak Oilfield Services
Company (a joint venture between Cook Inlet Region, Inc. and Nabors Industries,
Inc.) and Chesapeake for the purpose of purchasing the Company's oilfield
service assets and providing rig moving, transportation and related site
construction services to the Company and others in the industry. The Company
sold its service company assets to Peak for $6.4 million, and simultaneously
invested $2.5 million in exchange for a 33.3% partnership interest in Peak. This
transaction resulted in recognition of a $1.8 million pre-tax gain during the
fourth fiscal quarter of 1996 (reported in interest and other revenues). A
deferred gain from the sale of service company assets of $0.9 million was
recorded as a reduction in the Company's investment in Peak and was amortized to
income over the estimated useful lives of the Peak assets. The Company's
investment in Peak was accounted for using the equity method, and resulted in
$0.5 million of income being included in interest and other revenues in fiscal
1997. The Company sold its partnership interest in Peak in June 1998.

Revenues from oil and gas service operations were $6.3 million in fiscal
1996. The related costs and expenses of these operations were $4.9 million for
the year ended June 30, 1996. The gross profit margin was 22% in fiscal 1996.
The gross profit margin derived from these operations is a function of drilling
activities in the period, costs of materials and supplies and the mix of
operations between lower margin trucking operations versus higher margin labor
oriented service operations.

Production Expenses and Taxes. Production expenses and taxes, which include
lifting costs, production taxes and excise taxes, increased to $15.1 million in
fiscal 1997, compared to $8.3 million in fiscal 1996. This increase was
primarily the result of increased production. On a unit production basis,
production expenses and taxes increased to $0.19 per Mcfe, compared to $0.14 per
Mcfe in fiscal 1996. During fiscal 1996, a high proportion of the Company's
production was from the Giddings Field, much of which qualified for Texas
severance tax exemptions.

Impairment of Oil and Gas Properties. Prior to January 1997, the Company had
completed operations on one exploratory well in each of three separate areas
outside Masters Creek in the Louisiana Trend. Between April 1997 and July 1997,
the Company completed operations on 10 Company operated exploratory wells
located outside Masters Creek in the Louisiana Trend that resulted in the
addition of only 0.5 Bcfe of proved reserves. Cumulative well costs on these
non-Masters Creek properties were approximately $43 million as of June 30, 1997.
Of the 10 wells, one was completed on April 15, 1997, one on May 3, 1997 and
eight after June 1, 1997. Based upon this information and similar data which had
become available from outside operated properties in these non-Masters Creek
areas of the Louisiana Trend, management determined that a significant portion
of its leasehold in the Louisiana Trend outside of Masters Creek was impaired.
During the quarters ended March 31, 1997 and June 30, 1997, the Company
transferred $7.6 million and $86.3 million, respectively, of non-Masters Creek
Louisiana Trend leasehold costs to the amortization base of the full-cost pool.

The weighted average oil and gas prices used to value the Company's proved
reserves declined from $20.90 per Bbl and $2.41 per Mcf at June 30, 1996 to
$18.38 per Bbl and $2.12 per Mcf at June 30, 1997. Drilling and equipment costs
escalated rapidly in the fourth quarter of fiscal 1997 due primarily to higher
day rates for drilling rigs, thus increasing the estimated future capital
expenditures to be incurred to develop the Company's proved undeveloped
reserves. The oil and gas price declines and the increased costs to drill and
equip wells caused the Company to eliminate 35 gross proved undeveloped
locations in the Knox Field which contained an estimated 45 net Bcfe of proved
undeveloped reserves. Similar factors, combined with unfavorable drilling and
production results, eliminated approximately 93 Bcfe of proved reserves in the
Giddings and Louisiana Trend areas.

In the Independence area of the Giddings Field of Texas, a single well
completed in late March 1997, which the Company had estimated to contain 15.7
Bcfe of Company reserves at March 31, 1997, was significantly and adversely
affected by another operator's offset well which damaged the reservoir and
reduced the Company's estimated ultimate recovery to 8.0 Bcfe of reserves.

In late June 1997, management reviewed its March 31, 1997 internal estimates
of proved reserves and related present value and, after giving effect to the
fourth quarter 1997 drilling and production results, oil and gas prices, higher
drilling and completion costs, and additional leasehold acquisition costs and
delay rentals, determined that the Company had less reserve potential than had
previously been estimated. As a result, management estimated that at June 30,
1997 the Company would have capitalized costs of oil and gas properties which
would exceed its full-cost ceiling by approximately $150 million to $200
million. On June 27, 1997, the Company issued a press release which included
this estimate. Subsequently, based on the Company's final year-end estimates of
its proved reserves and related estimated future net revenues, which took into
account additional drilling and production results, management determined that
as of June 30, 1997, its capitalized costs exceeded its full-cost ceiling by
approximately $236 million. No such writedown was experienced by the Company in
fiscal 1996.

Oil and Gas Depreciation, Depletion and Amortization. DD&A of oil and gas
properties for fiscal 1997 was $103.3 million, $52.4 million higher than fiscal
1996's expense of $50.9 million. The expense in fiscal 1997 excluded the effects
of the asset writedown. The average DD&A rate per Mcfe, which is a function of
capitalized costs, future development costs, and the related underlying reserves
in the periods presented, increased to $1.31 in fiscal 1997 compared to $0.85 in
fiscal 1996.

Depreciation and Amortization of Other Assets. D&A of other assets increased
to $3.8 million in fiscal 1997, compared to $3.2 million in fiscal 1996. This
increase in fiscal 1997 was caused by an increase in D&A as a result of
increased investments in depreciable buildings and equipment and increased
amortization of debt issuance costs as a result of the issuance of senior notes
in May 1995, April 1996 and March 1997.




30
31

General and Administrative. G&A expenses, which are net of capitalized
internal payroll and non-payroll expenses (see Note 11 of Notes to Consolidated
Financial Statements), were $8.8 million in fiscal 1997, up 83% from $4.8
million in fiscal 1996. The increase in fiscal 1997 compared to fiscal 1996 is
due primarily to increased personnel expenses required by the Company's growth
and industry wage inflation. The Company capitalized $3.9 million of internal
costs in fiscal 1997 directly related to the Company's oil and gas exploration
and development efforts, compared to $1.7 million in 1996.

Interest and Other Income. Interest and other income for fiscal 1997 was
$11.2 million compared to $3.8 million in fiscal 1996. During fiscal 1997, the
Company realized $8.7 million in interest, $1.6 million of other investment
income, $0.5 million from its investment in Peak, and $0.4 million in other
income. During fiscal 1996, the Company realized $3.7 million of interest and
other investment income and a $1.8 million gain related to the sale of certain
service company assets, offset by a $1.7 million loss due to natural gas basis
changes in April 1996 as a result of the Company's hedging activities.

Interest Expense. Interest expense increased to $18.6 million in fiscal 1997
as compared to $13.7 million in 1996. Interest expense in the fourth quarter of
fiscal 1997 was $8.7 million, reflecting the issuance of $300 million of senior
notes in March 1997. In addition to the interest expense reported, the Company
capitalized $12.9 million of interest during fiscal 1997, compared to $6.4
million capitalized in fiscal 1996.

Provision (Benefit) for Income Taxes. The Company recorded an income tax
benefit of $3.6 million for fiscal 1997, before consideration of the $3.8
million tax benefit associated with the extraordinary loss from the early
extinguishment of debt, compared to income tax expense of $12.9 million in 1996.
All of the income tax expense in 1996 was deferred due to tax net operating
losses and carryovers resulting from the Company's drilling program.

The Company's loss before income taxes and extraordinary item of $180.3
million created a tax benefit for financial reporting purposes of $67.7 million.
However, due to limitations on the recognition of deferred tax assets, the total
tax benefit was reduced to $3.6 million.

At June 30, 1997, the Company had a net operating loss carryforward of
approximately $300 million for regular federal income taxes which will expire in
future years beginning in 2007. Management believed that it could not be
demonstrated at that time that it was more likely than not that the deferred
income tax assets, comprised primarily of the net operating loss carryforward,
would be realizable in future years, and therefore a valuation allowance of
$64.1 million was recorded in fiscal 1997. A deferred tax benefit related to the
exercise of employee stock options of approximately $4.8 million was allocated
directly to additional paid-in capital in 1997, compared to $7.9 million in
1996.

LIQUIDITY AND CAPITAL RESOURCES

For the Years Ended December 31, 1998 and 1997

Cash Flows from Operating Activities. Cash provided by operating activities
(inclusive of changes in working capital) decreased to $94.6 million in the
Current Year, compared to $181.3 million in the Prior Year. This decrease of
$86.7 million was due primarily to reduced operating income resulting from
significant decreases in average oil and gas prices between periods, as well as
significant increases in G&A expenses and interest expense.

Cash Flows from Investing Activities. Cash used in investing activities
increased to $548.1 million in the Current Year, compared to $476.2 million in
the Prior Year. This increase was due primarily to the $279.9 million used to
acquire certain oil and gas properties and companies with oil and gas reserves
during the Current Year. However, the increase in cash used to acquire oil and
gas properties was partially offset by reduced expenditures during the Current
Year for exploratory and developmental drilling. During the Current Year and
Prior Year, the Company invested $260 million and $471 million, respectively,
for exploratory and developmental drilling. Also during the Current Year, the
Company sold its 19.9% stake in Pan East Petroleum Corp. to Poco Petroleums,
Ltd.



31
32

for approximately $21.2 million. During the Prior Year the Company received net
proceeds from the sale of its investment in Bayard common stock of approximately
$73.8 million.

Cash Flows from Financing Activities. Cash provided by financing activities
increased to $363.8 million in the Current Year, compared to $278.0 million in
the Prior Year. During the Current Year, the Company retired $85 million of debt
assumed at the completion of the DLB Oil & Gas, Inc. acquisition, $120 million
of debt assumed at the completion of the Hugoton Energy Corporation acquisition,
$90 million of senior notes, and $170 million of borrowings made under its
commercial bank credit facilities. During the Current Year, the Company issued
$500 million in senior notes and $230 million in preferred stock. During the
Prior Year, the Company issued $300 million of senior notes.

For the Six Months Ended December 31, 1997 and 1996

Cash Flows from Operating Activities. Cash provided by operating activities
(inclusive of changes in components of working capital) increased to $139.2
million in the Transition Period, compared to $41.9 million in the Prior Period.
The primary reason for the increase was significant changes in the components of
current assets and liabilities, specifically $92 million of short-term
investments which were converted into cash during the Transition Period.

Cash Flows from Investing Activities. Cash used in investing activities
decreased to $136.5 million in the Transition Period, compared to $184.1 million
in the Prior Period. This decrease in cash used in investing activities was due
primarily to the $90.4 million received from the sale of the Company's
investment in Bayard common stock during the Transition Period, offset by other
investments. Approximately $189.8 million was expended by the Company in the
Transition Period for development and exploration of oil and gas properties, as
compared to $186.8 million in the Prior Period. In the Transition Period, other
property and equipment additions were $27.0 million primarily as a result of its
$11.9 million investment in the Louisiana Chalk Gathering System and Masters
Creek Gas Plant as well as additional investments in its Oklahoma City office
complex.

Cash Flows from Financing Activities. Cash used in financing activities was
$2.8 million during the Transition Period, compared to cash provided by
financing activities of $231.3 million during the Prior Period. The decrease was
due primarily to the proceeds received from the issuance of common stock during
the Prior Period of $288.1 million, which was partially offset by the net
payments on long-term borrowings of $56.8 million during the Prior Period.

For the Fiscal Years Ended June 30, 1997 and 1996

Cash Flows from Operating Activities. Cash provided by operating activities
(inclusive of changes in components of working capital) decreased to $84.1
million in fiscal 1997, compared to $121.0 million in fiscal 1996. The primary
reason for the decrease from fiscal 1996 to 1997 was significant changes in the
components of current assets and liabilities, specifically $102.9 million of
short-term investments at June 30, 1997.

Cash Flows from Investing Activities. Significantly higher cash was used in
fiscal 1997 for development, exploration and acquisition of oil and gas
properties compared to fiscal 1996. Approximately $524 million was expended by
the Company in fiscal 1997 (net of proceeds from sale of leasehold, equipment
and other), compared to $344 million in fiscal 1996. Net cash proceeds received
by the Company for sales of oil and gas equipment, leasehold and other decreased
to approximately $3.1 million in fiscal 1997, compared to $6.2 million in fiscal
1996. In fiscal 1997, other property and equipment additions were $34 million
primarily as a result of its $16.8 million investment in the Louisiana Chalk
Gathering System and Masters Creek Gas Plant as well as additional investments
in its Oklahoma City office complex.

Cash Flows from Financing Activities. On December 2, 1996, the Company
completed a public offering of 8,972,000 shares of common stock at a price of
$33.63 per share resulting in net proceeds to the Company of approximately
$288.1 million. Approximately $55.0 million of the proceeds was used to defease
the Company's




32
33

$47.5 million senior notes due 2001, and $11.2 million of the proceeds was used
to retire all amounts outstanding under the Company's commercial bank credit
facilities.

On March 17, 1997, the Company concluded the sale of $150 million of 7.875%
senior notes due 2004, and $150 million of 8.5% senior notes due 2012, which
offering resulted in net proceeds to the Company of approximately $292.6
million. The 7.875% senior notes were issued at 99.92% of par and the 8.5%
senior notes were issued at 99.414% of par. The 7.875% senior notes and the 8.5%
senior notes are redeemable at the option of the Company at any time at the
redemption or make-whole prices set forth in the respective indentures.

In fiscal 1996, cash flows from financing activities were $219.5 million,
largely as the result of the issuance of 5,989,500 shares of common stock (net
proceeds to the Company of approximately $99.4 million) and $120 million of
9.125% senior notes due 2006.

Financial Flexibility and Liquidity

The Company had a working capital deficit of $13 million at December 31,
1998 and a cash balance of $30 million. The Company has a $50 million revolving
bank credit facility, which matures in August 1999, with an initial committed
borrowing base of $50 million. As of December 31, 1998, the Company had borrowed
$25 million under this facility, which was included in the working capital
deficit as a short-term obligation. Borrowings under the facility are secured by
certain producing oil and gas properties and bear interest at a rate of 7.75%
per annum as of December 31, 1998.

The senior note indentures contain various restrictions for the Company and
its restricted subsidiaries to incur additional indebtedness. As of December 31,
1998, the Company estimates that secured commercial bank indebtedness of $115
million could have been incurred within these restrictions. This restriction
does not apply to borrowings incurred by CEMI, an unrestricted subsidiary.

The senior note indentures also limit the Company's ability to make
restricted payments (as defined), including the payment of preferred stock
dividends, unless certain tests are met. As of December 31, 1998, the Company
was unable to meet the requirements to incur additional unsecured indebtedness,
and consequently was not able to pay cash dividends on its 7% cumulative
convertible preferred stock on 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. 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.

Debt ratings for the senior notes are B3 by Moody's Investors Service and B
by Standard & Poor's Corporation as of March 19, 1999, and both have placed the
Company on review with negative implications. There are no scheduled principal
payments required on any of the senior notes until March 2004.

The Company believes it has adequate resources, including cash on hand,
budgeted cash flow from operations and proceeds from miscellaneous asset sales,
to fund its capital expenditure budget for exploration and development
activities during 1999, which are currently estimated to be approximately $90
million. The Company anticipates proceeds from miscellaneous asset sales will be
approximately $45 million during 1999. However, continued low oil and gas prices
or unfavorable drilling results could cause the Company to further reduce its
drilling program, which is largely discretionary.

YEAR 2000

Project. The Company has placed a high priority on proactively resolving
computer or embedded 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




33
34

would most typically be caused by erroneous date calculations, which result 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 remedial actions, identifying an appropriate action, then implementing and
testing. In addition, the Company is taking 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 third quarter of 1999. The production
accounting system in use at the Company is also scheduled for upgrade to a Year
2000 compliant version during the first half of 1999. The timing of these
upgrades have been scheduled to be concurrent with the respective vendors'
support requirements and to take advantage of additional feature or 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.
Preliminary versions of the system have been installed and are being tested. As
part of the testing, Year 2000 compliance will be assured. 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 include testing of
desktop PCs, 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:

<TABLE>
<CAPTION>
PHASE
ASSESSMENT/ REMEDIATION/
COMPONENT INVENTORY PRIORITIZATION CONTINGENCY
------------------------------ ------------- -------------- -------------
<S> <C> <C> <C>
Software March 1999 May 1999 September 1999
Hardware March 1999 April 1999 June 1999
Business partners March 1999 May 1999 June 30, 1999
Embedded systems (non-IT systems) May 1999 June 1999 September 1999
</TABLE>

In addition to the above, during the third 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 minimal consulting costs for Year
2000 project planning and scope definition. The Company plans to acquire a Year
2000 assessment and testing suite in early 1999 for approximately $50,000 and to
use contract staff to assist in the financial systems upgrade at a projected
cost of $70,000. For currently identified software systems requiring a Year 2000
upgrade, the vendor is providing that upgrade under the terms of existing
maintenance agreements, and thus no additional license or upgrade fees are
required. 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, nor has any project been deferred because of Year
2000 concerns or efforts. 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 a serious adverse impact on the





34
35

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 reasonably likely worst case
scenario if the Company and material business partners do not achieve Year 2000
compliance on a timely basis. The Company currently intends to complete its
contingency planning by September 30, 1999, with testing and training to take
place early in the fourth quarter.

RECENTLY ISSUED ACCOUNTING STANDARDS

On June 15, 1998, the Financial Accounting Standards Board issued FAS No.
133, Accounting for Derivative Instruments and Hedging Activities ("FAS 133").
FAS 133 establishes a new model for accounting for derivatives and hedging
activities and supersedes and amends a number of existing standards. FAS 133 is
effective for all fiscal quarters of fiscal years beginning after June 15, 1999.

FAS 133 standardizes the accounting for derivative instruments by requiring
that all derivatives be recognized as assets and liabilities and measured at
fair value. The accounting for changes in the fair value of derivatives (gains
and losses) depends on (i) whether the derivative is designated and qualifies as
a hedge, and (ii) the type of hedging relationship that exists. Changes in the
fair value of derivatives that are not designated as hedges or that do not meet
the hedge accounting criteria in FAS 133 are required to be reported in
earnings. In addition, all hedging relationships must be designated, reassessed
and documented pursuant to the provisions of FAS 133. The Company has not yet
determined the impact that adoption of FAS 133 will have on the financial
statements.

FORWARD LOOKING STATEMENTS

This Form 10-K includes "forward-looking statements" within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. All statements other than statements of historical facts

reflected in such forward-looking statements are reasonable, it can give no
assurance that such expectations will prove to have been correct. Factors that
could cause actual results to differ materially from those expected by the
Company, including, without limitation, factors discussed under Risk Factors in
Item 1 of this Form 10-K, are substantial indebtedness, impairment of asset
value, need to replace reserves, substantial capital requirements, ability to
supplement capital resources with asset sales, fluctuations in the prices of oil
and gas, uncertainties inherent in estimating quantities of oil and gas
reserves, projecting future rates of production and the timing of development
expenditures, competition, operating risks, restrictions imposed by lenders,
liquidity and capital requirements, the effects of governmental and
environmental regulation, pending patent and securities litigation, adverse
changes in the market for the Company's oil and gas production and the Company's
ability to successfully address Year 2000 issues. Readers are cautioned not to
place undue reliance on these forward-looking statements, which speak only as of
the date hereof. The Company undertakes no obligation to release publicly the
result of any revisions to these forward-looking statements that may be made to
reflect events or circumstances after the date hereof, including, without
limitation, changes in the Company's business strategy or planned capital
expenditures, or to reflect the occurrence of unanticipated events.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

COMMODITY PRICE RISK

The Company's results of operations are highly dependent upon the prices
received for oil and natural gas production.




35
36

Periodically the Company utilizes hedging strategies to hedge the price of a
portion of its future oil and gas production. These strategies include (i) 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, (ii)
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, (iii) 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
(iv) basis protection swaps, which are arrangements that guarantee the price
differential of oil or gas from a specified delivery point or points. Results
from commodity hedging transactions are reflected in oil and gas sales to the
extent related to the Company's oil and gas production. The Company only enters
into commodity hedging transactions related to the Company's oil and gas
production volumes or CEMI's physical purchase or sale commitments. Gains or
losses on crude oil and natural gas hedging transactions are recognized as price
adjustments in the months of related production.

As of December 31, 1998, the Company had the following natural gas swap
arrangements designed to hedge a portion of the Company's domestic gas
production for periods after December 1998:

</TABLE>

During 1998, the Company closed transactions for natural gas previously
hedged for the period April 1999 through November 1999 for net proceeds of $0.5
million.

Subsequent to December 31, 1998, the Company entered into additional natural
gas swap arrangements for 6,100,000 MMBtu at a strike price of $1.875 for the
period from June 1999 through September 1999. Such swap arrangements, along with
those listed above and other miscellaneous transactions, were closed as of March
15, 1999, resulting in net proceeds of $4.7 million.

As of December 31, 1998, the Company had the following natural gas swap
arrangements designed to hedge a portion of the Company's Canadian gas
production for periods after December 1998:

</TABLE>

If the swap arrangements listed above had been settled on December 31, 1998,
the Company would have incurred a loss of $0.2 million. Subsequent to December
31, 1998, the Company settled the swap arrangements listed above for the periods
of January 1999 and February 1999 resulting in a $0.4 million loss.

In addition to commodity hedging transactions related to the Company's oil
and gas production, CEMI periodically enters into various hedging transactions
designed to hedge against physical purchase commitments made by CEMI. Gains or
losses on these transactions are recorded as adjustments to Oil and Gas
Marketing Sales in the consolidated statements of operations and are not
considered by management to be material.

INTEREST RATE RISK

The Company also utilizes hedging strategies to manage fixed-interest rate
exposure. Through the use of a swap arrangement, the Company believes it can
benefit from stable or falling interest rates and reduce its current interest
expense. For the year ended December 31, 1998, the Company's interest rate swap
resulted in a $0.7 million reduction of interest expense.

The table below presents principal cash flows and related weighted average
interest rates by expected maturity dates. As of December 31, 1998, the carrying
amounts of short-term borrowings are representative of fair values because of
the short-term maturity of these instruments. The fair value of the long-term
debt has been estimated based on quoted market prices.

The Company changed its fiscal year end from June 30 to December 31 in 1997.
The Company's results of operations and cash flows for the six months ended
December 31, 1997 (the "Transition Period") are included in these consolidated
financial statements.

Principles of Consolidation

The accompanying consolidated financial statements of Chesapeake Energy
Corporation include the accounts of its direct and indirect wholly-owned
subsidiaries (the "Company"). All significant intercompany accounts and
transactions have been eliminated. Investments in companies and partnerships
which give the Company significant influence, but not control, over the investee
are accounted for using the equity method.

Accounting Estimates

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the dates of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.

Cash Equivalents

For purposes of the consolidated financial statements, the Company considers
investments in all highly liquid debt instruments with maturities of three
months or less at date of purchase to be cash equivalents.

Investments in Securities

The Company invests in various equity securities and short-term debt
instruments including corporate bonds and auction preferreds, commercial paper
and government agency notes. The Company has classified all of its short-term
investments in equity and debt instruments as trading securities, which are
carried at fair value with unrealized holding gains and losses included in
earnings. At December 31, 1998 and 1997, the Company had an unrealized holding
loss of $0 and $2.4 million, respectively, included in interest and other
income. At June 30, 1997, the Company had an unrealized holding loss of $0.6
million included in interest and other income. At June 30, 1996 the Company had
no trading securities. Investments in equity securities and limited partnerships
that do not have readily determinable fair values are stated at cost and are
included in noncurrent other assets. In determining realized gains and losses,
the cost of securities sold is based on the average cost method.

Inventory

Inventory consists primarily of tubular goods and other lease and well
equipment which the Company plans to utilize in its ongoing exploration and
development activities and is carried at the lower of cost or market using the
specific identification method.

Oil and Gas Properties

The Company follows the full-cost method of accounting under which all costs
associated with property acquisition, exploration and development activities are
capitalized. The Company capitalizes internal costs that can be directly
identified with its acquisition, exploration and development activities and does
not include any costs related to production, general corporate overhead or
similar activities (see Note 11). Capitalized costs are amortized on a composite
unit-of-production method based on proved oil and gas reserves. As of December
31, 1998, approximately 76% of the Company's proved reserve value (based on SEC
PV10%) was evaluated by independent petroleum engineers, with the balance
evaluated by the Company's engineers. In addition, the company's engineers
evaluate all properties quarterly. The average composite rates used for
depreciation, depletion and amortization were $1.13 ($1.17 in U.S. and $0.43 in
Canada) per equivalent Mcf in 1998, $1.57 per equivalent Mcf in the Transition
Period and $1.31 and $0.85 per equivalent Mcf in fiscal 1997 and 1996,
respectively.

Proceeds from the sale of properties are accounted for as reductions to
capitalized costs unless such sales involve a significant change in the
relationship between costs and the value of proved reserves or the underlying
value of unproved properties, in which case a gain or loss is recognized. The
costs of unproved properties are excluded from amortization until the properties
are evaluated. The Company reviews all of its unevaluated properties quarterly
to determine whether or not and to what extent proved reserves have been
assigned to the properties, and otherwise if impairment has occurred.
Unevaluated properties are grouped by major producing area where individual
property costs are not significant, and assessed individually when individual
costs are significant.

The Company reviews the carrying value of its oil and gas properties under
the full-cost accounting rules of the Securities and Exchange Commission on a
quarterly basis. Under these rules, capitalized costs, less accumulated
amortization and related deferred income taxes, shall not exceed an amount equal
to the sum of the present value of estimated future net revenues less estimated
future expenditures to be incurred in developing and producing the proved
reserves, less any related income tax effects. During 1998, capitalized costs of
oil and gas properties exceeded the estimated present value of future net
revenues from the Company's proved reserves, net of related income tax
considerations, resulting in writedowns in the carrying value of oil and gas
properties of $826 million. During the Transition Period, capitalized costs of
oil and gas properties exceeded the estimated present value of future net
revenues from the Company's proved reserves, net of related income tax
considerations, resulting in a writedown in the carrying value of oil and gas
properties of $110 million. During fiscal 1997, capitalized costs of oil and gas
properties exceeded the estimated present value of future net revenues from the
Company's proved reserves, net of related income tax considerations, resulting
in a writedown in the carrying value of oil and gas properties of $236 million.

Other Property and Equipment

Other property and equipment consists primarily of gas gathering and
processing facilities, vehicles, land, office buildings and equipment, and
software. Major renewals and betterments are capitalized while the costs of
repairs and maintenance are charged to expense as incurred. The costs of assets
retired or otherwise disposed of and the applicable accumulated depreciation are
removed from the accounts, and the resulting gain or loss is reflected in
operations. Other property and equipment costs are depreciated on both
straight-line and accelerated methods. Buildings are depreciated on a
straight-line basis over 31.5 years. All other property and equipment are
depreciated over the estimated useful lives of the assets, which range from five
to seven years.

Capitalized Interest

During 1998, the Transition Period and fiscal 1997 and 1996, interest of
approximately $6.5 million, $5.1 million, $12.9 million and $6.4 million was
capitalized on significant investments in unproved properties that were not
being currently depreciated, depleted, or amortized and on which exploration
activities were in progress.

Service Operations

Certain subsidiaries of the Company performed contract services on wells the
Company operated as well as for third parties until June 30, 1996. Oil and gas
service operations revenues and costs and expenses reflected in the accompanying
consolidated statement of operations for fiscal 1996 include amounts derived
from certain of the contractual services provided. The Company's economic
interest in its oil and gas properties was not affected by the performance of
these contractual services and all intercompany profits have been eliminated.

On June 30, 1996, Peak USA Energy Services, Ltd., a limited partnership
("Peak"), was formed by Peak Oilfield Services Company (a joint venture between
Cook Inlet Region, Inc. and Nabors Industries, Inc.) and the Company for the
purpose of purchasing the Company's oilfield service assets and providing rig
moving, transportation and related site construction services. The Company sold
its service company assets to Peak for $6.4 million and simultaneously invested
$2.5 million in exchange for a 33.3% partnership interest in Peak. This
transaction resulted in recognition of a $1.8 million pre-tax gain during the
fourth fiscal quarter of 1996 reported in interest and other. A deferred gain
from the sale of service company assets of $0.9 million was amortized to income
over the estimated useful lives of the Peak assets. The Company sold its
partnership interest in Peak in June 1998.

Income Taxes

The Company has adopted Statement of Financial Accounting Standards No. 109,
Accounting for Income Taxes ("SFAS 109"). SFAS 109 requires deferred tax
liabilities or assets to be recognized for the anticipated future tax effects of
temporary differences that arise as a result of the differences in the carrying
amounts and the tax bases of assets and liabilities.

Net Income (Loss) Per Share

In February 1997, the Financial Accounting Standards Board 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 1998, the Transition Period and fiscal
1997, there was no difference between actual weighted average shares
outstanding, which are used in computing basic EPS, and diluted weighted average
shares, which are used in computing diluted EPS. Options to purchase 11.3
million, 8.3 million and 7.9 million shares of common stock at weighted average
exercise prices of $1.86, $5.49 and $7.09 were outstanding during 1998, the
Transition Period and fiscal 1997 but were not included in the computation of
diluted EPS because the effect of these outstanding options would be
antidilutive. A reconciliation for fiscal 1996 is as follows:

Gas Imbalances -- Revenue Recognition

Revenues from the sale of oil and gas production are recognized when title
passes, net of royalties. The Company follows the "sales method" of accounting
for its gas revenue whereby the Company recognizes sales revenue on all gas sold
to its purchasers, regardless of whether the sales are proportionate to the
Company's ownership in the property. A liability is recognized only to the
extent that the Company has a net imbalance in excess of the remaining gas
reserves on the underlying properties. The Company's net imbalance positions at
December 31, 1998 and 1997 and June 30, 1997 were not material.

Hedging

The Company periodically uses certain instruments to hedge its exposure to
price fluctuations on oil and natural gas transactions and interest rates.
Recognized gains and losses on hedge contracts are reported as a component of
the related transaction. Results of oil and gas hedging transactions are
reflected in oil and gas sales to the extent related to the Company's oil and
gas production, in oil and gas marketing sales to the extent related to the
Company's marketing activities, and in interest expense to the extent so
related.

Debt Issue Costs

Included in other assets are costs associated with the issuance of the
Senior Notes. The remaining unamortized costs on these issuances of Senior Notes
at December 31, 1998 totaled $19.7 million and are being amortized over the life
of the Senior Notes.

Comprehensive Income

In 1998, the Company adopted SFAS No. 130, Reporting Comprehensive Income.
This statement establishes rules for the reporting of comprehensive income and
its components. Comprehensive income consists of net income and foreign currency
translation adjustments and is presented in the Consolidated Statements of
Stockholders' Equity (Deficit) and Comprehensive Income (Loss). The adoption of
SFAS 130 had no impact on total stockholders' equity. Prior year financial
statements have been reclassified to conform to the SFAS 130 requirements. All
balance sheet accounts of foreign operations are translated into U.S. dollars at
the year-end rate of exchange and statement of operations items are translated
at the weighted average exchange rates for the year.

Reclassifications

Certain reclassifications have been made to the consolidated financial
statements for the Transition Period and the years ended June 30, 1997 and 1996
to conform to the presentation used for the December 31, 1998 consolidated
financial statements.

2. SENIOR NOTES

On April 22, 1998, the Company issued $500 million principal amount of
9.625% Senior Notes due 2005 ("9.625% Senior Notes"). The 9.625% Senior Notes
are redeemable at the option of the Company at any time on or after May 1, 2002
at the redemption prices set forth in the indenture or at the make-whole prices,
as set forth in the indenture, if redeemed prior to May 1, 2002. The Company may
also redeem at its option up to $167 million of the 9.625% Senior Notes at
109.625% of their principal amount with the proceeds of an equity offering
completed prior to May 1, 2001.

On March 17, 1997, the Company issued $150 million principal amount of
7.875% Senior Notes due 2004 ("7.875% Senior Notes"). The 7.875% Senior Notes
are redeemable at the option of the Company at any time prior to




48
49

March 15, 2004 at the make-whole prices determined in accordance with the
indenture.

Also on March 17, 1997, the Company issued $150 million principal amount of
8.5% Senior Notes due 2012 ("8.5% Senior Notes"). The 8.5% Senior Notes are
redeemable at the option of the Company at any time prior to March 15, 2004 at
the make-whole prices determined in accordance with the indenture and, on or
after March 15, 2004 at the redemption prices set forth therein.

On April 9, 1996, the Company issued $120 million principal amount of 9.125%
Senior Notes due 2006 ("9.125% Senior Notes"). The 9.125% Senior Notes are
redeemable at the option of the Company at any time prior to April 15, 2001 at
the make-whole prices determined in accordance with the indenture and, on or
after April 15, 2001 at the redemption prices set forth therein. The Company may
also redeem at its option at any time on or prior to April 15, 1999 up to $42
million of the 9.125% Senior Notes at 109.125% of the principal amount thereof
with the proceeds of an equity offering.

On May 25, 1995, the Company issued $90 million principal amount of 10.5%
Senior Notes due 2002 ("10.5% Senior Notes"). In April 1998, the Company
purchased all of its 10.5% Senior Notes for approximately $99 million. The early
retirement of these notes resulted in an extraordinary charge of $13.3 million.

The Company is a holding company and owns no operating assets and has no
significant operations independent of its subsidiaries. The Company's
obligations under the 9.625% Senior Notes, the 9.125% Senior Notes, the 7.875%
Senior Notes and the 8.5% Senior Notes have been fully and unconditionally
guaranteed, on a joint and several basis, by each of the Company's "Restricted
Subsidiaries" (as defined in the respective indentures governing the Senior
Notes) (collectively, the "Guarantor Subsidiaries"). Each of the Guarantor
Subsidiaries is a direct or indirect wholly-owned subsidiary of the Company.

The senior note indentures contain certain covenants, including covenants
limiting the Company and the Guarantor Subsidiaries with respect to asset sales;
restricted payments; the incurrence of additional indebtedness and the issuance
of preferred stock; liens; sale and leaseback transactions; lines of business;
dividend and other payment restrictions affecting Guarantor Subsidiaries;
mergers or consolidations; and transactions with affiliates. The Company is
obligated to repurchase the 9.625% and 9.125% Senior Notes in the event of a
change of control or certain asset sales.

The senior note indentures also limit the Company's ability to make
restricted payments (as defined), including the payment of preferred stock
dividends, unless certain tests are met. As of December 31, 1998, the Company
was unable to meet the requirements to incur additional unsecured indebtedness,
and consequently was not able to pay cash dividends on its 7% cumulative
convertible preferred stock on February 1, 1999 (in the amount of $4,025,000).
Subsequent payments will be subject to the same restrictions and are dependent
upon variables that are beyond the Company's ability to predict. 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.

Set forth below are condensed consolidating financial statements of the
Guarantor Subsidiaries, the Company's subsidiaries which are not guarantors of
the Senior Notes (the "Non-Guarantor Subsidiaries") and the Company. Separate
audited financial statements of each Guarantor Subsidiary have not been provided
because management has determined that they are not material to investors.

Chesapeake Energy Marketing, Inc. ("CEMI") was a Non-Guarantor Subsidiary
for all periods presented, and the following were additional Non-Guarantor
Subsidiaries: Chesapeake Acquisition Corporation during the Transition Period,
Chesapeake Canada Corporation during fiscal 1997, and Chesapeake Gas Development
Corporation during fiscal 1996. All of the Company's other subsidiaries were
Guarantor Subsidiaries during these periods.

4. CONTINGENCIES AND COMMITMENTS

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 have filed a motion to dismiss. No estimate of loss or range of
estimate of loss, if any, can be made at this time.

Another purported class action alleging violations of the Securities Act of
1933 and the Oklahoma Securities Act is pending against the Company and others
on behalf of investors who purchased common stock of Bayard Drilling
Technologies, Inc. ("Bayard") in its initial public offering in November 1997.
Total proceeds of the offering were $254 million, of which the Company received
net proceeds of $90.2 million as a selling shareholder. Plaintiffs allege that
the Company, which owned 30.1% of Bayard's common stock outstanding prior to the
offering, was a controlling person of Bayard. Plaintiffs also allege that the
Company had established an interlocking financial relationship with Bayard and
was a customer of Bayard's drilling services under allegedly below-market terms.
Plaintiffs also note the fact that three executive officers and directors of the
Company were formerly directors 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. The 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 these actions are without merit and has filed a motion to dismiss.
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 drilling method, tortious interference
with confidentiality contracts between UPRC and certain of its former employees
and misappropriation of proprietary information of UPRC. UPRC's 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, enhanced, consequential and
punitive damages, interest, costs and attorneys' fees. In May 1998, the court
ruled as a matter of law that UPRC's tort claims for misappropriation of trade
secrets and tortious interference with business relations are barred by the
statute of limitations. Further, the court found that UPRC's claim for
inducement to infringe its patent for a drillbit steering method is barred as to
any wells drilled by the Company prior to August 14, 1995. The only issues
remaining in the case involve the validity, potential infringement and value, if
any, of UPRC's patent. The Company believes that it has meritorious defenses to
UPRC's allegations and has petitioned the court to declare the UPRC patent
invalid. Various motions for summary judgment are pending. No estimate of a
probable loss or range of estimate of a probable 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. This case has been set for trial in June 1999 on the issue of
liability.

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.

The Company has employment contracts with its two principal shareholders and
its chief financial officer and various other senior management personnel which
provide for annual base salaries, bonus compensation and various benefits. The
contracts provide for the continuation of salary and benefits for the respective
terms of the agreements in the event of termination of employment without cause.
These agreements expire at various times from June 30, 2000 through June 30,
2003.

Due to the nature of the oil and gas business, the Company and its
subsidiaries are exposed to possible environmental risks. The Company has
implemented various policies and procedures to avoid environmental contamination
and risks from environmental contamination. The Company is not aware of any
potential material environmental issues or claims.

5. INCOME TAXES

The components of the income tax provision (benefit) for each of the periods
are as follows:

</TABLE>

SFAS 109 requires that the Company record a valuation allowance when it is
more likely than not that some portion or all of the deferred tax assets will
not be realized. In 1998, the Transition Period and fiscal 1997, the Company
recorded an $826 million writedown, a $110 million writedown and a $236 million
writedown, respectively, related to the impairment of oil and gas properties.
The writedowns and significant tax net operating loss carryforwards (caused
primarily by expensing intangible drilling costs for tax purposes) resulted in a
net deferred tax asset at December 31, 1998 and 1997 and June 30, 1997.
Management believes it is more likely than not that the Company will generate
future tax net operating losses for at least the next five years.. Therefore,
the Company has recorded a valuation allowance equal to the net deferred tax
asset.

At December 31, 1998, the Company had U.S. and Canadian regular tax net
operating loss carryforwards of approximately $571 million and $1 million,
respectively, and U.S. alternative minimum tax net operating loss carryforwards
of approximately $196 million. The U.S. loss carryforward amounts will expire
during the years 2007 through 2018. The Company also had a percentage depletion
carryforward of approximately $4 million at December 31, 1998, which is
available to offset future federal income taxes payable and has no expiration
date.

In accordance with certain provisions of the Tax Reform Act of 1986, a
change of greater than 50% of the beneficial ownership of the Company within a
three-year period (an "Ownership Change") would place an annual limitation on
the Company's ability to utilize its existing tax carryforwards. Under
regulations issued by the Internal Revenue Service, the Company has had two
Ownership Changes. However, management believes this will not result in a
significant limitation of the tax carryforwards. Acquired tax carryforwards are
subject to separate limitations; however, management believes these will not
result in a significant limitation of the acquired tax carryforwards.

6. RELATED PARTY TRANSACTIONS

Certain directors, shareholders and employees of the Company have acquired
working interests in certain of the Company's oil and gas properties. The owners
of such working interests are required to pay their proportionate share of all
costs. As of December 31, 1998 and 1997 and June 30, 1997, the Company had
accounts receivable




59
60

from related parties, primarily related to such participation, of $5.6 million,
$4.2 million and $7.4 million, respectively.

Certain officers of the Company have loans due on December 31, 1999 to CEMI
in the principal amount of $9.9 million. Such loans, which were first made in
July 1998, are collateralized and carry an annual interest rate of 9.125%.

During 1998, the six months ended December 31, 1997 and fiscal 1997 and
1996, the Company incurred legal expenses of $493,000, $388,000, $207,000 and
$347,000, respectively, for legal services provided by a law firm of which a
director is a member.

7. EMPLOYEE BENEFIT PLANS

The Company maintains the Chesapeake Energy Corporation Savings and
Incentive Stock Bonus Plan, a 401(k) profit sharing plan. Eligible employees may
make voluntary contributions to the plan which are matched by the Company for up
to 10% of the employee's annual salary with the Company's common stock. The
amount of employee contribution is limited as specified in the plan. The Company
may, at its discretion, make additional contributions to the plan. The Company
contributed $1,359,000, $418,000, $603,000 and $187,000 to the plan during 1998,
the six months ended December 31, 1997 and the fiscal years ended June 30, 1997
and 1996, respectively.

8. MAJOR CUSTOMERS AND SEGMENT INFORMATION

</TABLE>

Management believes that the loss of any of the above customers would not
have a material impact on the Company's results of operations or its financial
position.

The Company believes all of its material operations are part of the oil and
gas industry, and therefore reports as a single industry setment. Beginning in
1998, the Company conducted foreign operations in Canada. The geographic
distribution of the Company's revenue, operating income and identifiable assets

9. STOCKHOLDERS' EQUITY AND STOCK BASED COMPENSATION

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

On April 28, 1998, the Company acquired by merger the Mid-Continent
operations of DLB Oil & Gas, Inc. ("DLB") for $17.5 million in cash, 5 million
shares of the Company's common stock, and the assumption of $90 million in
outstanding debt and working capital obligations.

On April 22, 1998, the Company issued $230 million (4.6 million shares) of
its 7% Cumulative Convertible Preferred Stock, $50 per share liquidation
preference, resulting in net proceeds to the Company of $223 million.

On March 10, 1998, the Company acquired Hugoton Energy Corporation
("Hugoton") pursuant to a merger by issuing approximately 25.8 million shares of
the Company's common stock in exchange for 100% of Hugoton's common stock.

On December 16, 1997, the Company acquired AnSon Production Corporation.
Consideration for this merger was approximately $43 million consisting of the
issuance of approximately 3.8 million shares of Company common stock and cash
consideration in accordance with the terms of the merger agreement.

On December 2, 1996, the Company completed a public offering of
approximately 9.0 million shares of common stock at a price of $33.63 per share,
resulting in net proceeds to the Company of approximately $288.1 million.

On April 12, 1996, the Company completed a public offering of approximately
6.0 million shares of common stock at a price of $17.67 per share, resulting in
net proceeds to the Company of approximately $99.4 million.

A 2-for-1 stock split of the common stock in December 1996, and a 3-for-2
stock split of the common stock in December 1995 and in June 1996 have been
given retroactive effect in these financial statements.

Stock Option Plans

Under the Company's 1992 Incentive Stock Option Plan (the "ISO Plan"),
options to purchase common stock may be granted only to employees of the Company
and its subsidiaries. Subject to any adjustment as provided by the ISO Plan, the
aggregate number of shares which may be issued and sold may not exceed 3,762,000
shares. The maximum period for exercise of an option may not be more than 10
years (or five years for an optionee who owns more than 10% of the common stock)
from the date of grant, and the exercise price may not be less than the fair
market value of the shares underlying the options on the date of grant (or 110%
of such value for an optionee who owns more than 10% of the common stock).
Options granted become exercisable at dates determined by the Stock Option
Committee of the Board of Directors. No options could be granted under the ISO
Plan after December 16, 1994.

Under the Company's 1992 Nonstatutory Stock Option Plan (the "NSO Plan"),
non-qualified options to purchase common stock may be granted only to directors
and consultants of the Company. Subject to any adjustment as provided by the NSO
Plan, the aggregate number of shares which may be issued and sold may not exceed
3,132,000 shares. The maximum period for exercise of an option may not be more
than 10 years from the date of grant, and the exercise price may not be less
than the fair market value of the shares underlying the options on the date of
grant. Options granted become exercisable at dates determined by the Stock
Option Committee of the Board of Directors. No options can be granted under the
NSO Plan after December 10, 2002.




61
62

Under the Company's 1994 Stock Option Plan (the "1994 Plan"), and its 1996
Stock Option Plan (the "1996 Plan"), incentive and nonqualified stock options to
purchase Common Stock may be granted to employees and consultants of the Company
and its subsidiaries. Subject to any adjustment as provided by the respective
plans, the aggregate number of shares which may be issued and sold may not
exceed 4,886,910 shares under the 1994 Plan and 6,000,000 shares under the 1996
Plan. The maximum period for exercise of an option may not be more than 10 years
from the date of grant and the exercise price may not be less than 75% of the
fair market value of the shares underlying the options on the date of grant.
Options granted become exercisable at dates determined by the Stock Option
Committee of the Board of Directors. No options can be granted under the 1994
Plan after December 16, 2004 or under the 1996 Plan after October 14, 2006.

The Company has elected to follow APB No. 25, Accounting for Stock Issued to
Employees and related interpretations in accounting for its employee stock
options. Under APB No. 25, compensation expense is recognized for the difference
between the option price and market value on the measurement date. No
compensation expense has been recognized because the exercise price of the stock
options equaled the market price of the underlying stock on the date of grant.

Pro forma information regarding net income and earnings per share is
required by SFAS No. 123 and has been determined as if the Company had accounted
for its employee stock options under the fair value method of the statement. The
fair value for these options was estimated at the date of grant using a
Black-Scholes option pricing model with the following weighted-average
assumptions for 1998, the six months ended December 31, 1997 and fiscal 1997 and
1996, respectively: interest rates (zero-coupon U.S. government issues with a
remaining life equal to the expected term of the options) of 5.20%, 6.45%, 6.74%
and 6.21%; dividend yields of 0.0%, 0.9%, 0.9% and 0.9%; volatility factors of
the expected market price of the Company's common stock of .96, .67, .60 and
.60; and weighted-average expected life of the options of four years.

The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion the existing models do not necessarily provide a reliable single measure
of the fair value of its employee stock options.

The Company's pro forma information follows:

<TABLE>

For purposes of the pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period, which is four
years. Because the Company's stock options vest over four years and additional
awards are typically made each year, the above pro forma disclosures are not
likely to be representative of the effects on pro forma net income for future
years. A summary of the Company's stock option activity and related information

The exercise of certain stock options results in state and federal income
tax benefits to the Company related to the difference between the market price
of the common stock at the date of disposition (or sale) and the option price.
During 1998, the six months ended December 31, 1997 and fiscal 1997 and 1996,
$0, $0, $4,808,000 and $7,950,000, respectively, were recorded as adjustments to
additional paid-in capital and deferred income taxes with respect to such tax
benefits.

10. FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES

The Company has only limited involvement with derivative financial
instruments, as defined in Statement of Financial Accounting Standards No. 119
"Disclosure About Derivative Financial Instruments and Fair Value of Financial
Instruments", and does not use them for trading purposes. The Company's primary
objective is to hedge a portion of its exposure to price volatility from
producing crude oil and natural gas. These arrangements may expose the Company
to credit risk from its counterparties and to basis risk. The Company does not
expect that the counterparties will fail to meet their obligations given their
high credit ratings.

Hedging Activities

Periodically the Company utilizes hedging strategies to hedge the price of a
portion of its future oil and gas production. These strategies include (i) 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, (ii)
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, (iii) 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
(iv) basis protection swaps, which are arrangements that guarantee the price
differential of oil or gas from a specified delivery point or points. Results
from commodity hedging transactions are




63
64

reflected in oil and gas sales to the extent related to the Company's oil and
gas production. The Company only enters into commodity hedging transactions
related to the Company's oil and gas production volumes or CEMI's physical
purchase or sale commitments. Gains or losses on crude oil and natural gas
hedging transactions are recognized as price adjustments in the months of
related production.

As of December 31, 1998, the Company had the following natural gas swap
arrangements designed to hedge a portion of the Company's domestic gas
production for periods after December 1998:

During 1998, the Company has closed transactions for natural gas previously
hedged for the period April 1999 through November 1999 for net proceeds of $0.5
million.

Subsequent to December 31, 1998, the Company entered into additional natural
gas swap arrangements for 6,100,000 MMBtu at a strike price of $1.875 for the
period from June 1999 through September 1999. Such swap arrangements, along with
those listed above and other miscellaneous transactions, were closed as of March
15, 1999, resulting in net proceeds of $4.7 million (unrealized gain of $0.8
million at December 31, 1998).

As of December 31, 1998, the Company had the following natural gas swap
arrangements designed to hedge a portion of the Company's Canadian gas
production for periods after December 1998:

In addition to commodity hedging transactions related to the Company's oil
and gas production, CEMI periodically enters into various hedging transactions
designed to hedge against physical purchase or sale commitments made by CEMI.
Gains or losses on these transactions are recorded as adjustments to oil and gas
marketing sales in the consolidated statements of operations and are not
considered by management to be material.

The Company also utilizes hedging strategies to manage fixed-interest rate
exposure. Through the use of a swap arrangement, the Company believes it can
benefit from stable or falling interest rates and reduce its current interest
expense. For the year ended December 31, 1998, the Company's interest rate swap
resulted in a $0.7 million reduction of interest expense during 1998.

Concentration of Credit Risk

Other financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash, short-term
investments in debt instruments and trade receivables. The Company's accounts
receivable are primarily from purchasers of oil and natural gas products and
exploration and production companies which own interests in properties operated
by the Company. The industry concentration has the potential to impact the
Company's overall exposure to credit risk, either positively or negatively, in
that the customers may be similarly affected by changes in economic, industry or
other conditions. The Company generally requires letters of credit for
receivables from customers which are judged to have sub-standard credit, unless
the credit risk can otherwise be mitigated. The cash and investments in debt
securities are with major banks or institutions with high credit ratings.

Fair Value of Financial Instruments

The following disclosure of the estimated fair value of financial
instruments is made in accordance with the requirements of Statement of
Financial Accounting Standards No. 107, "Disclosures About Fair Value of
Financial Instruments". The estimated fair value amounts have been determined by
the Company using available market information and valuation methodologies.
Considerable judgment is required in interpreting market data to develop the
estimates of fair value. The use of different market assumptions or valuation
methodologies may have a material effect on the estimated fair value amounts.

The carrying values of items comprising current assets and current
liabilities approximate fair values due to the short-term maturities of these
instruments. The Company estimates the fair value of its long-term, fixed-rate
debt using quoted market prices. The Company's carrying amount for such debt at
December 31, 1998 and 1997 and June 30, 1997 was $919.1 million, $509.0 million
and $508.9 million, respectively, compared to approximate fair values of $654.7
million, $517.0 million and $514.1 million, respectively. The carrying value of
other long-term debt approximates its fair value as interest rates are primarily
variable, based on prevailing market rates. The Company estimates the fair value
of its convertible preferred stock, which was issued in April 1998, using quoted
market prices. The Company's carrying amount for such preferred stock at
December 31, 1998 was $230 million, compared to an approximate fair value of
$48.9 million.

Unproved properties not subject to amortization at December 31, 1998 and
1997, and June 30, 1997 consisted mainly of lease acquisition costs. The Company
capitalized approximately $6.5 million, $5.1 million and $12.9 million of
interest during 1998, the six months ended December 31, 1997 and the year ended
June 30, 1997 on significant investments in unproved properties that were not
yet included in the amortization base of the full-cost pool. The Company will
continue to evaluate its unevaluated properties; however, the timing of the
ultimate evaluation and disposition of the properties has not been determined.

(a) Production costs include lease operating expenses and production taxes.

(b) The imputed income tax provision is hypothetical (at the statutory rate) and
determined without regard to the Company's deduction for general and
administrative expenses, interest costs and other income tax credits and
deductions, nor whether the hypothetical tax benefits will be realized.

Capitalized costs, less accumulated amortization and related deferred income
taxes, cannot exceed an amount equal to the sum of the present value (discounted
at 10%) of estimated future net revenues less estimated future expenditures to
be incurred in developing and producing the proved reserves, less any related
income tax effects. During 1998, capitalized costs of oil and gas properties
exceeded the estimated present value of future net revenues from the Company's
proved reserves, net of related income tax considerations, resulting in a
writedown in the carrying value of oil and gas properties of $826 million. At
December 31, 1997, capitalized costs of oil and gas properties exceeded the
estimated present value of future net revenues for the Company's proved
reserves, net of related income tax considerations, resulting in a writedown in
the carrying value of oil and gas properties of $110 million. At June 30, 1997,
capitalized costs of oil and gas properties also exceeded the estimated present
value of future net revenues for the Company's proved reserves, net of related
income tax considerations, resulting in a writedown in the carrying value of oil
and gas properties of $236 million.

Oil and Gas Reserve Quantities (unaudited)

The reserve information presented below is based upon reports prepared by
independent petroleum engineers and the Company's petroleum engineers. As of
December 31, 1998, Williamson Petroleum Consultants, Inc. ("Williamson"), Ryder
Scott Company Petroleum Engineers, H.J. Gruy and Associates, Inc. and the
Company's internal reservoir engineers evaluated 63%, 12%, 1% and 24% of the
Company's combined discounted future net revenues from the Company's estimated
proved reserves, respectively. As of December 31, 1997, Williamson, Porter
Engineering Associates, Netherland, Sewell & Associates, Inc. and internal
reservoir engineers evaluated approximately 53%, 42%, 3% and 2% the Company's
combined discounted future net revenues from the Company's estimated proved
reserves, respectively. As of June 30, 1997 and 1996, the reserves evaluated by

69

Williamson constituted approximately 41% and 99% of the company's combined
discounted future net revenues from the Company's estimated proved reserves,
respectively, with the remaining reserves being evaluated internally. The
reserves evaluated internally in fiscal 1997 were subsequently evaluated by
Williamson with a variance of approximately 4% of total proved reserves. The
information is presented in accordance with regulations prescribed by the
Securities and Exchange Commission. The Company emphasizes that reserve
estimates are inherently imprecise. The Company's reserve estimates were
generally based upon extrapolation of historical production trends, analogy to
similar properties and volumetric calculations. Accordingly, these estimates are
expected to change, and such changes could be material and occur in the near
term as future information becomes available.

Proved oil and gas reserves represent the estimated quantities of crude oil,
natural gas, and natural gas liquids which geological and engineering data
demonstrate with reasonable certainty to be recoverable in future years from
known reservoirs under existing economic and operating conditions. Proved
developed oil and gas reserves are those expected to be recovered through
existing wells with existing equipment and operating methods. As of December 31,
1997, all of the Company's oil and gas reserves were located in the United
States.

Presented below is a summary of changes in estimated reserves of the Company
for 1998, the six months ended December 31, 1997 and for the fiscal years 1997
and 1996:

During 1998, the Company acquired approximately 750 Bcfe of proved reserves
through merger or through purchases of oil and gas properties. The total
consideration given for the acquisitions was 30.8 million shares of Company
common stock, $280 million of cash, the assumption of $205 million of debt, and
the incurrence of approximately $20 million of other acquisition related costs.
Also during 1998, the Company recorded downward revisions to the December 31,
1997 estimates of approximately 4,082 MBbl and 60,477 MMcf, or approximately 85
Bcfe. These reserve revisions were primarily attributable to lower oil and gas
prices at December 31, 1998. The weighted average prices used to value the
Company's reserves at December 31, 1998 were $10.48 per barrel of oil and $1.68
per Mcf of gas, as compared to the prices used at December 31, 1997 of $17.62
per barrel of oil and $2.29 per Mcf of gas.

For the six months ended December 31, 1997, the Company recorded downward
revisions to the June 30, 1997 reserve estimates of approximately 3,428 MBbl and
24,189 MMcf, or approximately 45 Bcfe. The reserve revisions were primarily
attributable to lower than expected results from development drilling and
production which eliminated certain previously established proven reserves.

On December 16, 1997, Chesapeake acquired AnSon Production Corporation, a
privately owned oil and gas producer based in Oklahoma City. Consideration for
this acquisition was approximately $43 million. The Company estimates that it
acquired approximately 26.4 Bcfe in connection with this acquisition.

For the fiscal year ended June 30, 1997, the Company recorded downward
revisions to the previous year's reserve estimates of approximately 5,989 MBbl
and 137,938 MMcf, or approximately 174 Bcfe. The reserve revisions were
primarily attributable to the decrease in oil and gas prices between periods,
higher drilling and completion costs, and unfavorable developmental drilling and
production results during fiscal 1997. Specifically, the Company recorded
aggregate downward adjustments to proved reserves of 159 Bcfe for the Knox,
Giddings and Louisiana Trend areas.

On April 30, 1996, the Company purchased interests in certain producing and
non-producing oil and gas properties, including approximately 14,000 net acres
of unevaluated leasehold, from Amerada Hess Corporation for

71

$37.8 million. The properties are located in the Knox and Golden Trend fields of
southern Oklahoma, most of which are operated by the Company. In fiscal 1996 the
reserves acquired from Amerada Hess Corporation were included in both
"extensions, discoveries and other additions" and "purchase of
reserves-in-place". The fiscal 1996 presentation has been restated to remove the
acquired reserves from "extensions, discoveries and other additions" with a
corresponding offset to "revisions of previous estimate". This revision resulted
in no net change to total oil and gas reserves.

Standardized Measure of Discounted Future Net Cash Flows (unaudited)

Statement of Financial Accounting Standards No. 69 ("SFAS 69") prescribes
guidelines for computing a standardized measure of future net cash flows and
changes therein relating to estimated proved reserves. The Company has followed
these guidelines which are briefly discussed below.

Future cash inflows and future production and development costs are
determined by applying year-end prices and costs to the estimated quantities of
oil and gas to be produced. Estimates are made of quantities of proved reserves
and the future periods during which they are expected to be produced based on
year-end economic conditions. Estimated future income taxes are computed using
current statutory income tax rates including consideration for the current tax
basis of the properties and related carryforwards, giving effect to permanent
differences and tax credits. The resulting future net cash flows are reduced to
present value amounts by applying a 10% annual discount factor.

The Company's reserve values were calculated using weighted average prices
at December 31, 1998 of $10.48 per barrel of oil and $1.68 per Mcf of natural
gas. If prices in future periods are below the average realized levels at
December 31, 1998, future impairment charges will likely be incurred.

The assumptions used to compute the standardized measure are those
prescribed by the Financial Accounting Standards Board and, as such, do not
necessarily reflect the Company's expectations of actual revenue to be derived
from those reserves nor their present worth. The limitations inherent in the
reserve quantity estimation process, as discussed previously, are equally
applicable to the standardized measure computations since these estimates are
the basis for the valuation process.

The following summary sets forth the Company's future net cash flows
relating to proved oil and gas reserves based on the standardized measure
prescribed in SFAS 69:

(a) Total revenue excluding interest and other income, less total costs and
expenses excluding interest and other expense.

Capitalized costs, less accumulated amortization and related deferred income
taxes, cannot exceed an amount equal to the sum of the present value of
estimated future net revenues less estimated future expenditures to be incurred
in developing and producing the proved reserves, less any related income tax
effects. At December 31, 1998, June 30, 1998, March 31, 1998, December 31, 1997
and June 30, 1997, capitalized costs of oil and gas properties exceeded the
estimated present value of future net revenues for the Company's proved
reserves, net of related income tax considerations, resulting in writedowns in
the carrying value of oil and gas properties of $360 million, $216 million, $250
million, $110 million and $236 million, respectively.

During the fourth quarter of 1998, the Company incurred a $55 million
impairment charge to adjust certain non-oil and gas assets to their estimated
fair values. Of this amount, $30 million related to the Company's investment in
preferred stock of Gothic Energy Corporation, and the remainder was related to
certain of the Company's gas processing and transportation assets located in
Louisiana.

14. ACQUISITIONS

During 1998, the Company acquired approximately 750 Bcfe of proved reserves
through merger or through purchases of oil and gas properties. The total
consideration given for the acquisitions was $280 million of cash,




75
76

30.8 million shares of Company common stock, the assumption of $205 million of
debt, and the incurrence of approximately $20 million of other acquisition
related costs.

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 informational purposes only and is not
necessarily indicative of what would have occurred if the acquisition had been
made as of those dates. In addition, the pro forma information is not intended
to be a projection of future results and does not reflect the efficiencies
expected to result from the integration of Hugoton.
