                                  THE COMPANY
 
     Chesapeake Energy Corporation is an independent energy company which
utilizes advanced drilling and completion technologies to explore for and
produce oil and natural gas. The Company ranks among the five most active
drillers of new wells in the United States.
 
     From its inception in 1989 through June 30, 1996, Chesapeake drilled a
total of 562 gross (186 net) wells, of which 529 gross (175 net) wells were
commercially productive. As a result of its successful drilling efforts, the
Company has experienced significant growth in its proved reserves, production,
revenue, and assets. From its first full fiscal year of operation ended June 30,
1990 to the fiscal year ended June 30, 1996, the Company's estimated proved
reserves increased to 425 Bcfe from 11 Bcfe, annual production increased to 60.2
Bcfe from 0.2 Bcfe, total revenue increased to $149.4 million from $0.6 million,
and total assets increased to $572 million from $8 million.
 
     At June 30, 1996, the Company's estimated proved reserves consisted of 12.3
MMBbl of oil and 351.2 Bcf of gas, a total of 425 Bcfe. During fiscal 1996, the
Company's proved reserves increased from 242 Bcfe to 425 Bcfe, an increase of
183 Bcfe, or a four-fold replacement of its 60.2 Bcfe of production. At June 30,
1996 the present value of estimated future net revenue attributable to
Chesapeake's estimated proved reserves before income taxes (utilizing a 10%
discount rate) was $547 million, based on average prices at fiscal year end 1996
of $20.90 per Bbl and $2.41 per Mcf. At June 30, 1996 the Company had an
inventory of approximately 900 undrilled locations (including 182 proved
undeveloped locations), providing the Company with an estimated five-year
inventory of drilling opportunities.
 
     The Company operates approximately 80% of the wells in which it owns an
interest. Of the 562 wells drilled by the Company through June 30, 1996, 275
were horizontal wells, reflecting the Company's emphasis on utilizing horizontal
drilling technology.
 
                               BUSINESS STRATEGY
 
     Since its inception, Chesapeake's business strategy has been growth through
the drillbit. Using this strategy, the Company has expanded its reserves and
production through the acquisition and subsequent development of large blocks of
acreage. The Company has focused its activities in areas where reservoirs such
as fractured carbonates offer low geological risk, large reserve potential, and
the opportunity to earn attractive economic returns through the application of
advanced drilling and completion technologies.
 
     The Company concentrates its undeveloped leasehold acquisition and
associated drilling in three primary operating areas: (i) the Giddings Field of
southern Texas, (ii) the Knox, Sholem Alechem, and Golden Trend fields of
southern Oklahoma, and (iii) the Louisiana Austin Chalk Trend (the "Louisiana
Trend") in eastern Texas and central Louisiana. In addition, the Company
continues to search for other areas in the United States and Canada where its
geological and engineering expertise provides the Company with competitive
advantages. The additional project areas identified to date include the
Williston Basin in eastern Montana and western North Dakota, the Arkoma Basin in
southeastern Oklahoma, and the Lovington area in eastern New
 
                                        3

Mexico. The Company seeks to achieve a balance between oil and gas production
and to retain a higher level of ownership in its project areas than it has
historically retained.
 
     The Company's operating areas are typically characterized by fractured
carbonate reservoirs that are known to contain oil and gas and generally cover a
large geographic area. In the past, development of these reservoirs has been
limited by both economic and technological factors. Recent advances in drilling
and completion technologies, and the resulting higher reserve recoveries and
lowered exploration costs, provide the Company with the opportunity to develop
large new reserves of oil and natural gas and to generate attractive economic
returns.
 
     The proceeds of the Offering will allow the Company to expand its
exploration and development activities and to reduce its debt. Management
believes that the Company's growth through the drillbit business strategy,
distinct competitive advantages and success to date provide the basis for
continued growth in reserves and production. Management further believes that
this Offering will provide a significantly improved capital structure that
should enable the Company to develop the large number of opportunities available
to it. To that end, management seeks to achieve an investment grade senior debt
rating during the next few years.
 
                             COMPETITIVE ADVANTAGES
 
     Management believes five competitive advantages are responsible for
Chesapeake's rapid growth and distinguish the Company from other independent
energy companies.
 
     Growth Through the Drillbit. Employing its strategy of growth through the
drillbit, the Company has substantially increased its reserves and production.
By focusing drilling efforts on reservoirs that respond favorably to the
application of advanced drilling and completion technologies, management
believes the Company can continue to increase its reserves and production and
generate attractive returns by integrating the Company's technical expertise
with its large inventory of undeveloped leasehold.
 
     Dominant Leasehold Positions. Through aggressive acreage acquisition in its
existing and new project areas, the Company seeks to establish a dominant
leasehold position in each of its project areas. Such a dominant position allows
the Company to maximize its economic returns while limiting drilling
opportunities available to its competitors. Consistent with this strategy, the
Company has assembled a significant leasehold acreage inventory which included
approximately 900 proved and unproved drilling locations at June 30, 1996.

     Technological Leadership. The Company has developed significant expertise
in the rapidly evolving technologies of horizontal drilling, 3-D seismic
evaluation, and deep fracture stimulation. The Company believes its expertise in
employing these technologies is the most important factor in its growth during
the past several years. In particular, the Company has developed considerable
horizontal drilling and completion expertise, especially in wells which target
deep fractured carbonates. Over the last several years, deeper, more complex
horizontal wells have become technically and economically feasible and the cost
of drilling these

wells has decreased. As a result, the Company believes there has been a
substantial increase in the number of areas which are economically attractive
for horizontal drilling.
 
     Superior Operating Margin. Management believes the Company's operating cost
structure is among the lowest of all publicly traded independent energy
producers. For fiscal 1996, the Company's per unit operating costs (consisting
of general and administrative expense, lease operating expense, production
taxes, and depreciation, depletion and amortization of oil and gas properties)
were $1.07 per Mcfe produced, resulting in an operating margin of $0.77 per
Mcfe. Management believes the key to creating value in the independent energy
industry is the ability to generate high levels of cash flow per Mcfe that can
be successfully reinvested in a technologically-driven exploration program.
 
     Management's Substantial Equity Ownership. At October 25, 1996, the
Company's management and directors beneficially owned (including outstanding
vested options) an aggregate of approximately 42% of the Company's outstanding
shares of Common Stock. Assuming completion of the Offering, management and
directors will continue to own approximately 37% of the Company's outstanding
Common Stock. Management believes this substantial equity ownership provides a
strong alignment of management's and investors' interests and creates an
entrepreneurial culture within the Company.
 
                            PRIMARY OPERATING AREAS
 
     The Company's activities are concentrated in three primary operating areas:
(i) the Navasota River and Independence areas of the downdip Giddings Field in
southern Texas, (ii) the Knox, Sholem Alechem, and Golden Trend fields of
southern Oklahoma, and (iii) the South Brookeland, Leesville, Masters Creek, St.
Landry, Baton Rouge and Livingston areas of the Louisiana Trend.
 
     The following table sets forth the Company's proved reserves in its primary

GIDDINGS FIELD
 
     Chesapeake's second largest concentration of proved reserves and its
highest concentration of present value are located in the Giddings Field, which
is one of the most active oil and natural gas fields in the U.S. The primary
producing formation in Giddings is the Austin Chalk formation, a fractured
carbonate reservoir found at depths ranging from 7,000 feet to 17,000 feet along
a 15,000 square mile trend in southeastern Texas and central Louisiana.
Chesapeake has concentrated its drilling efforts in the gas-prone downdip
portion of the Giddings Field, where the Austin Chalk is located at depths below
11,000 feet. The Company believes the downdip Giddings area is one of the
largest discoveries of onshore gas in the U.S. in recent years.
 
     The Company believes that its success in the downdip Giddings Field is
attributable to four principal factors: (i) limited reservoir drainage from
previously drilled vertical wells; (ii) the Company's aggressive leasehold
acquisition program, which has permitted the creation of larger spacing units,
thus reducing competition for reserves from offsetting wells; (iii) continued
technological advances in horizontal drilling,
 
                                        5

which have significantly lowered development costs, expanded the field's
boundaries into deeper areas, and increased per well productivity through the
ability to drill within a more precisely defined target zone; and (iv) the
geological setting of the downdip Austin Chalk, which is characterized by
greater reservoir pressure and more intensive fracturing than in the updip area
of the Giddings Field. As a result of these factors, the Company's downdip wells
have, on average, produced greater reserves per well while also exhibiting lower
decline rates than average wells in other areas of Austin Chalk production in
Texas.
 
     Navasota River. In February 1994, the Company drilled its first well in the
Navasota River leasehold block, located in Brazos and Grimes Counties, Texas. As
of June 30, 1996, the Company had successfully completed 77 of 77 Navasota River
wells and was drilling seven additional wells. The Company has budgeted $30
million in fiscal 1997 to drill 28 gross (16 net) wells in the Navasota River
area.
 
     Independence. The Company's Independence block is located in Grimes and
Washington Counties to the south and southwest (and further downdip) from the
Navasota River area. As of June 30, 1996, the Company had successfully completed
24 of 26 Independence wells and was drilling two additional wells. The Company
has budgeted $7 million to drill six gross (three net) wells in fiscal 1997 in
the Independence area.
 
SOUTHERN OKLAHOMA
 
     Chesapeake's largest concentration of proved reserves is located in
southern Oklahoma and is comprised of the Knox, Golden Trend and Sholem Alechem
fields. Based on the Company's drilling success in late 1993 with its deeper
wells (12,000 to 14,000 feet) in the Bradley area of the Golden Trend Field, the
Company initiated a deeper drilling project in 1994 in the Knox area. The
Company's first two wells in Knox were the first wells in Oklahoma to establish
commingled commercial production from the Sycamore, Woodford, Hunton and Viola
formations at depths below 15,000 feet. This success led to an aggressive and
successful acreage acquisition and drilling program during fiscal 1995 and
fiscal 1996.
 
     Knox. As of June 30, 1996, Chesapeake had successfully completed 41 of 42
wells drilled in the Knox Field and was drilling six additional wells. The
Company's acreage inventory in the Knox area is large enough to support the
drilling of approximately 50 proved undeveloped locations. The Company believes
this inventory could increase by up to 150 increased density or step-out wells,
subject to continued drilling success and applicable spacing requirements.
During fiscal 1996, Chesapeake doubled its assets in Knox and the Golden Trend
through its acquisition of Amerada Hess Corporation's interests in Chesapeake
wells. The Company has budgeted $36 million in fiscal 1997 to drill 19 gross (15
net) wells in the Knox area.
 
     Sholem Alechem. The Company's horizontal drilling project in the Sholem
Alechem portion of southern Oklahoma's Sho-Vel-Tum Field was initiated on the
Company's belief that the application of horizontal drilling technology could
result in a significant increase in the recovery of remaining reserves in this
field. Since its discovery more than 80 years ago, the Sho-Vel-Tum Field has
produced more than one billion barrels of oil and one trillion cubic feet of
natural gas. To date, the Company has successfully completed 25 of 25 horizontal
wells in the Sycamore formation. The Company believes other fractured carbonates
that underlie the Sycamore, such as the Hunton and McLish formations, may also
be commercially productive as the result of the application of horizontal
drilling. Texaco Exploration and Production, Inc. is the Company's 50% working
interest partner in this area. The Company has budgeted $8 million to drill 10
gross (five net) Sholem Alechem wells during fiscal 1997.
 
LOUISIANA AUSTIN CHALK TREND
 
     The Louisiana Trend is the newest of the Company's three primary operating
areas and will be central to the Company's exploration and development
activities over the next several years. In late 1994, Occidental Petroleum
Corporation ("Occidental") announced the completion of a single lateral
horizontal Austin Chalk discovery well in the Masters Creek area of central
Louisiana. Occidental's well was drilled 200 miles east of the Company's
activity in the downdip Giddings Field and 60 miles east of the nearest previous
commercial multi-well horizontal Austin Chalk production in the Brookeland Field
of southeast Texas.
 
                                        6
<PAGE>   7
 
     Based on management's judgment that the Occidental well confirmed the
Company's geological premise that the Austin Chalk would be productive across a
large portion of central and southeastern Louisiana, Chesapeake invested
approximately $125 million through September 30, 1996 to acquire approximately
1,050,000 acres of leasehold in the Louisiana Trend.
 
     Through November 18, 1996, Chesapeake had commenced drilling operations on
13 operated wells in the Louisiana Trend. Of these 13 wells, three are
producing, three are waiting on completion, one has been temporarily abandoned
and six are drilling. Production commenced from Chesapeake's first operated
well, the Laddie James #7-1, on June 30, 1996, and the Cloud #9-1 on September
10, 1996. Cumulative production from the Laddie James #7-1 was 2.3 Bcfe and from
the Cloud #9-1 was 0.8 Bcfe through November 6, 1996. The Company has also
participated in three successful wells operated by others. Chesapeake has
budgeted $125 million to drill 25 gross and net wells in the Louisiana Trend
during fiscal 1997, including several wells that will test the deeper Tuscaloosa
formation.
 
  OTHER OPERATING AREAS
 
     Williston Basin. During fiscal 1996, Chesapeake began acquiring leasehold
in the Williston Basin, located in eastern Montana and western North Dakota, and
as of June 30, 1996 owned approximately 550,000 gross (450,000 net) acres. The
primary focus of Chesapeake's exploration efforts in the southern portion of
this basin (325,000 net acres) is a horizontal drilling target, the oil-prone
Red River "B" formation in Bowman and Slope Counties, North Dakota and in Fallon
County, Montana. Approximately 75 Red River "B" horizontal wells have been
drilled to date by other companies in this area. The Company's first Red River
"B" well, the State #1-16, is currently drilling.
 
     In the northern portion of the Williston Basin (125,000 net acres), the
Company is focusing its exploratory efforts on drilling vertical wells to the
Red River "C" and "D" formations using 3-D seismic. The Company's first well,
the Vitt #1-5, was completed from the Red River "C" formation in late October
1996 for initial daily production of 300 Bbls and 200 Mcf. The Company has
budgeted approximately $6 million to drill six gross (six net) Williston wells
in fiscal 1997, but expects to increase these activities if drilling results
continue to be favorable.
 
     Lovington. In late 1994, the Company initiated activity in the Lovington
portion of the Permian Basin of Lea County, New Mexico. In this project, the
Company is utilizing 3-D seismic technology to search for algal mound buildups
that management believes have been overlooked in this portion of the Permian
Basin because of inconclusive results provided by traditional 2-D seismic
technology. The first well operated by the Company on one of its 3-D seismic
surveys in the Lovington area is the Ruth #1-20. This well was completed in late
October 1996 for initial daily production of 600 Bbls and 250 Mcf from the
Strawn formation.
 
     The Company has identified approximately 50 prospects in the Lovington
area, where the Company is targeting oil reserves at depths from 11,000 to
13,000 feet. The Company has budgeted $4 million to drill six gross (five net)
wells during fiscal 1997, but expects to increase these activities if drilling
results continue to be favorable.
 
                              RECENT DEVELOPMENTS
 
     In September 1996, the Company entered into two agreements to enhance the
natural gas gathering and processing infrastructure in the Masters Creek and St.
Landry areas of the Louisiana Trend. The first agreement, with Mitchell Energy &
Development Corp. ("Mitchell"), involves the construction of a pipeline and an
associated gathering system capable of transporting up to 350 MMcf of natural
gas per day from the Company's wells in the central portion of the Louisiana
Trend to Enron Louisiana Energy Company's ("Enron") Eunice natural gas
processing and fractionating facility. This system will be constructed by a
50/50 joint venture between the Company and Mitchell, with Mitchell as the
operating partner. Construction of the
 
                                        7
<PAGE>   8
 
system is expected to be completed in the third quarter of fiscal 1997. The
Company's share of costs for this venture will be approximately $15 million.
 
     In a related agreement, Enron will upgrade its Eunice facility so that it
can treat, process and fractionate the Company's raw natural gas that will be
delivered to Eunice via the Louisiana Chalk Gathering System. Based on
production to date from wells in the Louisiana Trend, the natural gas produced
from the Masters Creek area is expected to be rich in natural gas liquids and,
once processed, should enable the Company to receive a premium to Henry Hub
pricing for its natural gas.
 
     In September 1996, the Company agreed to sell to Koch Oil Company at
market-sensitive prices the Company's crude oil and condensate production in the
Masters Creek, Leesville and South Brookeland portions of the Louisiana Trend.
Koch will construct a 10-inch crude oil pipeline system into this area of
Louisiana from the Nederland and Beaumont areas of Texas. The construction of
this pipeline should enable the Company to access Gulf Coast oil markets,
currently the most favorably priced oil markets in the United States.
 
     On November 5, 1996, the Company began production at its Lawton #25-1 well
at the initial daily rate of 4,700 Bbls of oil and 10 MMcf. Additionally, the
Company has reached total depth in its Thomas #40-1 and believes the well is a
significant Tuscaloosa discovery. Testing of this well is expected to commence
in the next two weeks. A summary of the Company's Louisiana Trend operated
drilling activity at November 8, 1996 is provided below.

                        SUMMARY OIL AND GAS RESERVE DATA
 
     The reserve information presented below is based upon reports prepared by
the independent petroleum engineering firm of Williamson Petroleum Consultants,
Inc. ("Williamson") and the Company's petroleum engineers as of June 30, 1996.
The reserves evaluated by the Company's petroleum engineers constituted 0.6% of
the Company's total proved reserves at such date. These estimates were based on
average prices realized by the Company at June 30, 1996 which resulted in
average prices over the life of the production of approximately $2.41 per Mcf
and $20.90 per Bbl.

                                  RISK FACTORS
 
     In addition to the other information set forth elsewhere or incorporated by
reference in this Prospectus, the following factors relating to the Company and
the Offering should be considered when evaluating an investment in the Common
Stock offered hereby.
 
CONCENTRATION IN LOUISIANA TREND
 
     In addition to the development of its existing proved reserves, the Company
expects that its inventory of unproved drilling locations will be the primary
source of new reserves, production and cash flow over the next few years. The
Louisiana Trend, in particular, is a key element of the existing inventory. The
Company had invested approximately $125 million through September 30, 1996 to
acquire approximately 1,050,000 acres of leasehold in the Louisiana Trend which
is largely undeveloped and unproven. Moreover, approximately 55% of the
Company's fiscal year 1997 drilling budget is associated with drilling and
acreage acquisition activity in the Louisiana Trend. There can be no assurance
that the Louisiana Trend will yield substantial economic returns. Failure of the
Louisiana Trend to yield significant quantities of economically attractive
reserves and production could have a material adverse impact on the Company's
future financial condition and results of operations and could result in a
write-off of a significant portion of its investment in the Louisiana Trend. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
NEED TO REPLACE RESERVES
 
     As is customary in the oil and gas exploration and production industry, the
Company's future success depends upon its ability to find, develop or acquire
additional oil and gas reserves that are economically recoverable. Unless the
Company successfully replaces the reserves that it produces through successful
development, exploration or acquisition, the Company's proved reserves will
decline. Further, 40% of the Company's proved reserves at June 30, 1996 were
located in the Austin Chalk trend, where wells are characterized by relatively
rapid decline rates. Additionally, approximately 60% of the Company's total
proved reserves at June 30, 1996 were undeveloped. Recovery of such reserves
will require significant capital expenditures and successful drilling
operations. There can be no assurance that the Company will continue to be
successful in its effort to develop or replace its proved reserves.
 
SUBSTANTIAL CAPITAL REQUIREMENTS
 
     The Company has made and intends to make substantial capital expenditures
in connection with the exploration and production of its oil and gas properties.
Historically, the Company has funded its capital expenditures through a
combination of internally generated funds, equity and long-term debt financing,
and short-term financing arrangements. The Company anticipates that the net
proceeds from the Offering, together with its cash flow from operations and the
availability of credit under the Company's revolving credit facility with Union
Bank (the "Revolving Credit Facility") will be sufficient to meet estimated
capital expenditures for fiscal 1997 and for fiscal 1998, including increases in
capital expenditures being presently evaluated. Future cash flows and the
availability of credit are subject to a number of variables, such as the level
of production from existing wells, prices of oil and gas and the Company's
success in locating and producing new reserves. If revenue were to decrease as a
result of lower oil and gas prices, decreased production or otherwise, and the
Company had no availability under the Revolving Credit Facility, the Company
could have a reduced ability to replace its reserves or to maintain production
at current levels, potentially resulting in a decrease in production and revenue
over time. If the Company's cash flow from operations and availability under its
Revolving Credit Facility are not sufficient to satisfy its capital expenditure
budget, there can be no assurance that additional debt or equity financing will
be available to meet these requirements.
 
STOCK PRICE VOLATILITY
 
     The sales price for the Company's Common Stock on the NYSE has been subject
to significant changes over short periods of time. See "Price Range of Common
Stock and Dividend Policy." This volatility has resulted from, among other
things, (i) the concentration of capital expenditures and potential returns tied
to
 
                                       12
<PAGE>   13
 
the Louisiana Trend, (ii) the price multiples at which the Company's Common
Stock has historically traded, (iii) the relatively large number of short sales
positions with respect to the Company Common Stock and (iv) rumors and
speculation concerning the Company's drilling activity.
 
PATENT LITIGATION
 
     On October 15, 1996, Union Pacific Resources Company ("UPRC") filed suit
against the Company in the United States District Court for the Northern
District of Texas alleging (a) infringement of UPRC's claimed patent (the "UPRC
Patent") for an invention involving a method of maintaining a bore hole in a
stratigraphic zone during drilling, and (b) tortious interference with contracts
between UPRC and a third party vendor regarding the confidentiality of
proprietary information of UPRC. UPRC is seeking injunctive relief, damages of
an unspecified amount, including actual, enhanced, consequential and punitive
damages, interest, costs and attorney's fees. The Company believes that it has
meritorious defenses to UPRC's allegations, including, without limitation, the
Company's belief that the UPRC Patent is invalid. Although the Company will
vigorously defend the lawsuit, no assurance can be given as to the outcome of
the matter or the ultimate impact on the Company of any damages (which could be
substantial) that may be awarded to UPRC because litigation is inherently
uncertain. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Legal Proceedings."
 
EFFECTS OF LEVERAGE
 
     At June 30, 1996, on a pro forma basis, after giving effect to the Offering
and the application of the net proceeds therefrom, the Company would have had
approximately $230 million of indebtedness, including current maturities of
long-term indebtedness, and stockholders' equity of $427 million. See
"Capitalization." The Company may incur additional indebtedness under the
Revolving Credit Facility.
 
     The instruments governing the indebtedness of the Company and its
subsidiaries impose significant operating and financial restrictions on the
Company. The terms of the indentures (the "Senior Notes Indentures") governing
the Company's outstanding 12% Senior Notes, 10.5% Senior Notes and 9.125% Senior
Notes (collectively, the "Senior Notes") and the Company's bank credit
facilities affect, and in many respects significantly limit or prohibit, among
other things, the ability of the Company to incur additional indebtedness, pay
dividends, repay indebtedness prior to its stated maturity, sell assets or
engage in mergers or acquisitions. These restrictions could also limit the
ability of the Company to effect future financing, make needed capital
expenditures, withstand a future downturn in the Company's business or the
economy in general, or otherwise conduct necessary corporate activities. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
COMMODITY PRICE FLUCTUATIONS
 
     The Company's revenue, profitability and future rate of growth are
substantially dependent upon prevailing prices for oil, gas and natural gas
liquids, which are dependent upon numerous factors such as weather, economic,
political and regulatory developments and competition from other sources of
energy. The volatile nature of the energy markets makes it particularly
difficult to estimate future prices of oil, gas and natural gas liquids. Prices
of oil, gas and natural gas liquids are subject to wide fluctuations in response
to relatively minor changes in circumstances, and there can be no assurance that
future prolonged decreases in such prices will not occur. All of these factors
are beyond the control of the Company. Any significant decline in oil and gas
prices could have a material adverse effect on the Company's operations,
financial condition and level of expenditures for the development of its oil and
gas reserves, and may result in violations of certain covenants contained in the
Company's credit agreements. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources."
 
WRITEDOWNS OF CARRYING VALUES
 
     The Company periodically reviews the carrying value of its oil and gas
properties under the full cost accounting rules of the Securities and Exchange
Commission (the "Commission"). Under these rules,
 
                                       13
<PAGE>   14
 
capitalized costs of oil and natural gas properties may not exceed the present
value of estimated future net revenues from proved reserves, discounted at 10%,
plus the lower of cost or fair market value of unproved properties. Application
of this "ceiling" test generally requires pricing future revenue at the
unescalated prices in effect as of the end of each fiscal quarter and requires a
writedown for accounting purposes if the ceiling is exceeded, even if prices
declined for only a short period of time, and even if prices increase in
subsequent periods. The risk that the Company will be required to write down the
carrying value of its oil and natural gas properties increases when oil and
natural gas prices are depressed or decline substantially, or if a large amount
of unevaluated leasehold were proven to be uneconomical to develop or were
abandoned. If a writedown is required, it would result in a one-time charge to
earnings, but would not impact cash flow from operating activities.
 
UNCERTAINTY OF ESTIMATES OF OIL AND GAS RESERVES
 
     There are numerous uncertainties inherent in estimating quantities of
proved oil and gas reserves, including many factors beyond the control of the
Company. The Company obtained an estimate of its proved oil and gas reserves and
the estimated future net revenue therefrom based upon a report prepared as of
June 30, 1996 by Williamson and the Company's petroleum engineers. The portion
of the reserves evaluated solely by the Company's petroleum engineers as of June
30, 1996 constituted 0.6% of the Company's total proved reserves at that date.
These estimates rely upon various assumptions, including assumptions required by
the Commission as to constant oil and gas prices, drilling and operating
expenses, capital expenditures, taxes and availability of funds. The process of
estimating oil and gas reserves is complex, requiring significant decisions and
assumptions in the evaluation of available geological, geophysical, engineering
and economic data for each reservoir. As a result such estimates are inherently
imprecise. Actual future production, revenue, taxes, development expenditures,
operating expenses and quantities of recoverable oil and gas reserves may vary
substantially from those estimated by the Company. Any significant variance in
these assumptions could materially affect the estimated quantity and value of
reserves set forth in this Prospectus. In addition, the Company's reserves may
be subject to downward or upward revision, based upon production history,
results of future exploration and development, prevailing oil and gas prices and
other factors, many of which are beyond the Company's control.
 
DRILLING AND OPERATING RISKS
 
     Oil and gas drilling activities are subject to numerous risks, many of
which are beyond the Company's control. The Company's operations may be
curtailed, delayed or canceled as a result of title problems, weather
conditions, compliance with governmental requirements, mechanical difficulties
and shortages or delays in the delivery of equipment. In addition, the Company's
properties may be susceptible to hydrocarbon drainage from production by other
operators on adjacent properties. Industry operating risks include 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 has been among the most active drillers of horizontal wells and
expects to drill a significant number of deep horizontal wells in the future.
The Company's horizontal drilling activities involve greater risk of mechanical
problems than conventional vertical drilling operations. In some cases, the
locations will require wells to be drilled to greater depths, which may involve
more complex drilling than wells drilled to date. These wells may be
significantly more expensive to drill than those drilled to date.
 
     In accordance with customary industry practice, the Company maintains
insurance against some, but not all, of the risks described above. There can be
no assurance that any insurance will be adequate to cover losses or liabilities.
The Company cannot predict the continued availability of insurance, or its
availability at premium levels that justify its purchase.
 
                                       14
<PAGE>   15
 
GOVERNMENTAL REGULATION
 
     Oil and gas operations are subject to various federal, state and local
governmental regulations which may be changed from time to time in response to
economic or political conditions. From time to time, regulatory agencies have
imposed price controls and limitations on production in order to conserve
supplies of oil and gas. In addition, the production, handling, storage,
transportation and disposal of oil and gas, by-products thereof and other
substances and materials produced or used in connection with oil and gas
operations are subject to regulation under federal, state and local laws and
regulations primarily relating to protection of human health and the
environment. To date, expenditures related to complying with these laws and for
remediation of existing environmental contamination have not been significant in
relation to the results of operations of the Company. There can be no assurance
that the trend of more expansive and stricter environmental legislation and
regulations will not continue.
 
COMPETITION
 
     The Company operates in a highly competitive environment. The Company
competes with major and independent oil and gas companies for the acquisition of
desirable oil and gas properties, as well as for the equipment and labor
required to develop and operate such properties. Many of these competitors have
financial and other resources substantially greater than those of the Company.
 
RELIANCE ON KEY PERSONNEL; CONFLICTS OF INTEREST
 
     The Company is dependent upon its Chief Executive Officer, Aubrey K.
McClendon, and its Chief Operating Officer, Tom L. Ward. The unexpected loss of
the services of either of these executive officers could have a detrimental
effect on the Company. The Company maintains $20 million key man life insurance
policies on the life of each of Messrs. McClendon and Ward.
 
     Messrs. McClendon and Ward, together with another executive officer of the
Company, have rights to, and do, participate in wells drilled by the Company.
Such participation may create interests which conflict with those of the
Company.
 
CONTROL BY CERTAIN STOCKHOLDERS
 
     At October 25, 1996, Aubrey K. McClendon, Tom L. Ward, the Aubrey K.
McClendon Children's Trust and the Tom L. Ward Children's Trust beneficially
owned an aggregate of 11,479,159 shares (including outstanding vested options)
representing approximately 38% (33% after giving effect to this Offering) of the
outstanding Common Stock, and members of the Company's Board of Directors and
senior management beneficially owned an aggregate of 13,278,449 shares
(including outstanding vested options), which, together with the shares
beneficially owned by Messrs. McClendon and Ward and their respective children's
trusts, represented approximately 42% (37% after giving effect to this Offering)
of the Company's outstanding Common Stock. As a result, Messrs. McClendon and
Ward, together with other officers and directors of the Company, are in a
position to effectively control the Company through their ability to
significantly influence matters requiring the vote or consent of the Company's
stockholders.
 
DIVIDEND RIGHTS AND RESTRICTIONS ON PAYMENT OF DIVIDENDS
 
     Holders of Common Stock will be entitled to receive dividends when, as and
if declared by the Board of Directors of the Company out of funds legally
available therefor. The Senior Notes Indentures and certain of the Company's
other credit agreements restrict the payment of dividends to the holders of the
Company's capital stock, including the Common Stock. As described under "Price
Range of Common Stock and Dividend Policy," the Company's current policy is to
retain its earnings to support its business. The determination of the amount of
future cash dividends, if any, to be declared and paid is in the sole discretion
of the Company's Board of Directors and will depend on the Company's financial
condition, earnings and funds from operations, the level of its capital and
exploration expenditures, dividend restrictions in its financing agreements, its
future business prospects and other matters as the Company's Board of Directors
deems relevant. The amount permitted under the Company's credit agreements and
the Senior Notes Indentures to
 
                                       15
<PAGE>   16
 
be used to pay dividends will vary over time depending on, among other things,
the Company's earnings and any future issuances of capital stock.

                                  THE COMPANY
 
     Chesapeake Energy Corporation is an independent energy company which
utilizes advanced drilling and completion technologies to explore for and
produce oil and natural gas. The Company's executive offices are located at 6100
North Western Avenue, Oklahoma City, Oklahoma 73118 and its telephone number is
(405) 848-8000.
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the Common Stock offered
hereby are estimated to be $256.5 million ($287.8 million if the over-allotment
option is exercised). The Company intends to use the net proceeds from the
Offering to reduce debt, to fund increased exploratory and development capital
expenditures and for general corporate purposes. The Company intends to use
approximately $53 million of the net proceeds to offer to purchase or otherwise
satisfy the Company's obligations in respect of $47.5 million principal amount
of the Company's outstanding 12% Senior Notes, and such additional amounts as
may be required to fully repay the outstanding balance of its Revolving Credit
Facility ($10 million principal amount at September 30, 1996). This Offering is
not contingent upon the Company's purchase of any amount of 12% Senior Notes.
The balance of the net proceeds will be used to fund an increase in the
Company's exploration and development capital expenditures and for general
corporate purposes. Pending such application of the net proceeds of the
Offering, such net proceeds will be invested in short-term, interest-bearing
instruments.
 
                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY

     The Company has not paid cash dividends on its Common Stock. The Company's
policy is to retain its earnings to support the growth of the Company's
business. In addition, the Senior Notes Indentures and other agreements with the
Company's lenders contain certain restrictions on the Company's ability to
declare and pay dividends. 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 restrictions imposed by the Company's present or future credit
facilities.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
     Chesapeake's revenue, net income, operating cash flow, and production
reached record levels in 1996. Increased cash flow from operations, in
combination with the issuance of $120 million of 9.125% Senior Notes and the
sale of approximately three million shares of Common Stock in April 1996,
allowed the Company to fund its net capital expenditures of $344 million.
 
     During fiscal 1996, the Company participated in 148 gross wells (69.0 net),
of which 111 were operated by the Company. The Company's proved reserves
increased by 183 Bcfe to 425 Bcfe as a result of this drilling and the purchase
of proved reserves from Amerada Hess Corporation compared to 60.2 Bcfe of
production, resulting in reserve replacement in excess of 300% compared to
production.
 
     The Company's business strategy has continued to emphasize the acquisition
of large prospective leasehold positions to provide a multi-year inventory of
drilling locations. By June 1996, the Company had increased its acreage position
to approximately 200,000 gross acres of developed leasehold and approximately
two million gross acres of undeveloped leasehold. During 1996, the Company
continued the expansion of its exploration focus in the Louisiana Trend and
began a significant acreage acquisition program in the Williston Basin. The
Company also conducted or participated in 3-D seismic programs in the Lovington
area, the Giddings Field, the Knox Field and in the Williston and Arkoma Basin
areas to evaluate the Company's acreage inventory.

RESULTS OF OPERATIONS
 
  YEAR ENDED JUNE 30, 1996 VS. JUNE 30, 1995 AND JUNE 30, 1994
 
     General. For the fiscal year ended June 30, 1996, the Company realized net
income of $23.4 million, or $0.80 per common share, on total revenues of $149.4
million. This compares to net income of $11.7 million, or
 
                                       20
<PAGE>   21
 
$0.42 per common share, on total revenues of $67.3 million in fiscal 1995, and
net income of $3.9 million, or $0.16 per common share, on total revenues of
$29.8 million in fiscal 1994. The significantly higher earnings in 1996 as
compared to 1995 and 1994 were largely the result of higher production and
prices per Mcfe, partially offset by higher oil and gas depreciation, depletion
and amortization and higher interest costs.
 
     Oil and Gas Sales. During fiscal 1996, oil and gas sales increased 94% to
$110.8 million versus $57.0 million for fiscal 1995 and 395% from the fiscal
1994 amount of $22.4 million. The increase in oil and gas sales resulted
primarily from strong growth in production volumes. For fiscal 1996, the Company
produced 60.2 Bcfe at a weighted average price of $1.84 per Mcfe, compared to
31.9 Bcfe produced in fiscal 1995 at a weighted average price of $1.78 per Mcfe,
and 10.2 Bcfe produced in fiscal 1994 at a weighted average price of $2.21 per
Mcfe. This represents production growth of 89% for fiscal 1996 compared to 1995
and 490% compared to 1994.
 
     These increases in production volumes reflect the Company's successful
exploration and development program. The following table shows the Company's
production by major field area for fiscal 1995 and fiscal 1996:

</TABLE>
 
     The Company's gas production represented approximately 86% of the Company's
total production volume on an equivalent basis in fiscal 1996. This is compared
to 79% in fiscal 1995 and 68% in 1994. This is a result of the Company's
drilling in deeper, more gas-prone areas of the Giddings and Knox Fields.
 
     For fiscal 1996, the Company realized an average price per barrel of oil of
$17.85, compared to $17.36 in fiscal 1995 and $15.09 in fiscal 1994. 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. In
fiscal 1996, the Company realized $0.9 million less in oil revenues than it
would have received from unhedged market prices.
 
     Gas price realizations increased from fiscal 1995 to 1996 by approximately
12%, despite lower gas revenue realized by the Company during the fourth fiscal
quarter of 1996 as a result of the hedging activity. As a result of hedging, the
Company had gas revenues during that period that were approximately $5.1 million
less than unhedged market prices. Although gas prices generally increased during
1996, the weighted average realization per Mcf in 1996 was still 19% less than
1994. The lower prices realized in 1995 were the result of lower natural gas
prices, and the fact that an increased portion of the Company's gas production
was from areas that contain leaner gas that is either not processed for liquids
or contains less energy value (Btu's) per Mcf. The Company anticipates gas
production in Louisiana will receive premium prices at least equivalent to Henry
Hub indexes due to the high Btu content and favorable market location of the
production.
 
     Gas Marketing Sales. In December 1995, the Company entered into the gas
marketing business by acquiring all of the outstanding stock of an Oklahoma
City-based natural gas marketing company for total consideration of $725,000.
This subsidiary provides natural gas marketing services including commodity
price
 
                                       21
<PAGE>   22
 
structuring, contract administration and nomination services for the Company,
its partners and other natural gas producers in the geographical areas in which
the Company is active.
 
     As a result of this purchase, the Company realized $28.4 million in gas
marketing sales for third parties in fiscal 1996, with corresponding costs of
gas marketing sales of $27.5 million, resulting in a gross margin of $0.9
million. There were no gas marketing activities in 1995 or 1994.
 
     Oil and Gas Service Operations. Revenues from oil and gas service
operations were $6.3 million in fiscal 1996, down 28% from $8.8 million in
fiscal 1995, and down 2% from $6.4 million in fiscal 1994. The related costs and
expenses of these operations were $4.9 million, $7.7 million and $5.2 million
for the three years ended June 30, 1996, 1995 and 1994, respectively. The gross
profit margin of 22% in fiscal 1996 was up from the 12% margin in fiscal 1995,
and up slightly from the 19% gross margin in fiscal 1994. 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.
 
     In June 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
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 will be amortized to income over the estimated useful lives of the
Peak assets. The Company's investment in Peak will be accounted for using the
equity method.
 
     Interest and Other. Interest and Other Revenues for fiscal 1996 was $3.8
million which compares to $1.5 million in 1995 and $1 million in 1994. During
fiscal 1996, the Company realized $3.7 million of interest and other 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. During 1995 and 1994, the Company
did not incur any such gains on sale of assets or basis losses.
 
     Production Expenses and Taxes. Production expenses and taxes, which include
lifting costs and production and excise taxes, increased to $8.3 million in
fiscal 1996, as compared to $4.3 million in fiscal 1995, and $3.6 million in
fiscal 1994. These increases on a year-to-year basis were primarily the result
of increased production. On a Mcfe production unit basis, production expenses
and taxes increased to $0.14 per Mcfe as compared to $0.13 per Mcfe in fiscal
1995 and $0.36 per Mcfe in 1994. Severance tax exemptions for production were
available in fiscal 1996 and 1995, and certain of the exemptions in the Giddings
Field are applicable for production through 2001 for wells spud prior to
September 1, 1996 and, on a more limited basis, for qualifying wells spud
thereafter. The Company expects that operating costs in fiscal 1997 will
increase because of the Company's expansion of drilling efforts into the
Louisiana Trend and the Williston Basin, both of which are oil prone areas with
significant associated water production which results in higher operating costs
than gas prone areas, and because limited severance tax exemptions will be
applicable in these areas as compared to existing exemptions in the Giddings
Field.
 
     Depreciation, Depletion and Amortization. Depreciation, depletion and
amortization ("DD&A") of oil and gas properties for fiscal 1996 was $50.9
million, $25.5 million higher than fiscal 1995's expense of $25.4 million, and
$42.8 million higher than fiscal 1994's expense of $8.1 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, increased
to $0.85 in fiscal 1996 compared to $0.80 in fiscal 1995 and 1994. The Company's
DD&A rate in the future will be a function of the results of future acquisition,
exploration, development and production results. The Company's DD&A rate will
increase in 1997 based on projected higher finding costs for the Louisiana
Trend.
 
     Depreciation and Amortization of Other Assets. Depreciation and
amortization ("D&A") of other assets increased to $3.2 million in fiscal 1996,
compared to $1.8 million in fiscal 1995, and $1.9 million in 1994. This
 
                                       22
<PAGE>   23
 
increase in fiscal 1996 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 and in April 1996. The Company anticipates an increase in D&A in
fiscal 1997 as a result of a full year of debt issuance cost amortization on the
9.125% Senior Notes issued in April 1996 and higher building depreciation
expense on the Company's corporate offices, offset by a reduction in
depreciation expense associated with the sale of the service company assets.
 
     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 $4.8 million in fiscal
1996, up 33% from $3.6 million in fiscal 1995, and up from $3.1 million in
fiscal 1994. The increases in fiscal 1996 compared to 1995 and 1994 result
primarily from increased personnel expenses required by the Company's growth.
The Company capitalized $1.7 million of internal costs in fiscal 1996 directly
related to the Company's oil and gas exploration and development efforts, as
compared to $0.6 million in 1995 and $1.0 million in 1994. The Company
anticipates that G&A costs for fiscal 1997 will increase by approximately 25% as
a result of the Company's continued growth and increased budgets for exploration
and development activities, increasing operations activities, and attendant
personnel and overhead requirements.
 
     Interest and Other. Interest and other expense increased to $13.7 million
in fiscal 1996 as compared to $6.6 million in 1995 and $2.7 million in fiscal
1994. Interest expense in the fourth quarter of fiscal 1996 was approximately $4
million, reflecting the issuance of $120 million of 9.125% Senior Notes in April
1996. In addition to the interest expense reported, the Company capitalized $6.4
million of interest during fiscal 1996, as compared to $1.6 million capitalized
in 1995 and $0.4 million in 1994. Interest expense will increase significantly
in fiscal 1997 as compared to 1996 as a result of the 9.125% Senior Notes issued
in April 1996.
 
     Income Tax Expense. The Company recorded income tax expense of $12.9
million in fiscal 1996, as compared to $6.3 million in fiscal 1995, and $1.3
million in 1994. All of the income tax expense in 1996 was deferred due to a
current year tax net operating loss resulting from the Company's active drilling
program. A substantial portion of the Company's drilling costs are currently
deductible for income tax purposes. The effective tax rate was approximately
35.5% in fiscal 1996 compared to a tax rate of 35% in 1995 and 24% in 1994. The
Company anticipates an effective tax rate of approximately 36.5% for fiscal 1997
as a result of Louisiana state taxes and higher activity levels in Louisiana.
Based upon the anticipated level of drilling activities in fiscal 1997, the
Company anticipates that substantially all of its fiscal 1997 income tax expense
will be deferred.
 
     Hedging. Periodically the Company utilizes hedging strategies to hedge the
price of a portion of its future oil and gas production. These strategies
include swap arrangements that establish an index-related price above which the
Company pays the hedging partner and below which the Company is paid by the
hedging partner, the purchase of index-related puts that provide for a "floor"
price to the Company to be paid by the counter-party to the extent the price of
the commodity is below the contracted floor, and basis protection swaps. Results
from hedging transactions are reflected in oil and gas sales to the extent
related to the Company's oil and gas production.
 
     As of June 30, 1996, the Company had NYMEX-based crude oil swap agreements
for 1,000 Bbl per day for July 1, 1996 through August 31, 1996 at an average
price of $17.85 per Bbl. The counter-party has the option exercisable monthly
for an additional 1,000 Bbl per day for the period July 1, 1996 through December
31, 1996 to cause a swap if the price exceeds an average $17.74 per Bbl. The
actual settlements for July, August and September resulted in a net $0.7 million
payment to the counter-parties. The Company estimates, based on NYMEX prices as
of October 24, 1996, that the effect of the October through December hedges
would be a net $0.7 million payment to the counter-parties.
 
                                       23
<PAGE>   24
 
     The Company has purchased Houston Ship Channel put options which guarantee
the Company an average floor price of $2.21/MMBtu for 20,000 MMBtu per day for
the period of November 1, 1996 through February 28, 1997. The average cost of
these puts was $0.14 per MMBtu.
 
     As of June 30, 1996, the Company had NYMEX-based natural gas swaps and
NYMEX/Houston Ship Channel basis swaps for the months of July through October
1996. These transactions resulted in payments to the Company's counter-parties
of approximately $3.7 million for the months of July, August and September, 1996
and $0.2 million for the month of October 1996.
 
     The Company has only limited involvement with derivative financial
instruments, as defined in SFAS No. 119 "Disclosure About Derivative Financial
Instruments and Fair Value of Financial Instruments" and does not use them for
trading purposes. The Company's 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 to its counter-parties and to basis risk.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  FINANCING ACTIVITIES
 
     In April 1996 the Company completed a public offering of 2,994,750 shares
of Common Stock at a price of $35.33 per share resulting in net proceeds to the
Company of approximately $99.4 million. In April 1996 the Company also concluded
the sale of $120 million of 9.125% Senior Notes at 99.931% of par, which
offering resulted in net proceeds to the Company of approximately $116 million,
and applied approximately $44 million of the proceeds to pay the balance
outstanding under the Revolving Credit Facility. Prior to April 15, 1999 the
Company may retire up to $42 million of the 9.125% Senior Notes at 109.125% of
par from the proceeds of an equity offering. The 9.125% Senior Notes are
redeemable at the option of the Company at any time at the redemption or
make-whole prices set forth in the Indenture.
 
     In fiscal 1995, cash flows from financing activities were $97.3 million,
including $90 million from the sale of 10.5% Senior Notes. The 10.5% Senior
Notes are redeemable after June 1, 1999 and prior to June 1, 1998, the Company
may retire up to $30 million of the 10.5% Senior Notes with the proceeds of an
equity offering at 110% of par.
 
     In fiscal 1994, the Company received $48.8 million from the issuance of
$47.5 million of 12% Senior Notes and warrants to purchase an aggregate of
2,190,937 shares of Common Stock. The Company must redeem $11.9 million of 12%
Senior Notes on each March 1, 1998, 1999 and 2000, and may redeem all 12% Senior
Notes after March 1, 1998. Immediately following this Offering, the Company
intends to purchase or otherwise satisfy its obligations in respect of all
outstanding 12% Senior Notes. See "Use of Proceeds."
 
     All of the Company's subsidiaries except Chesapeake Gas Development
Corporation ("GCDC") and Chesapeake Energy Marketing Inc. ("CEMI") have fully
and unconditionally guaranteed on a joint and several basis all Senior Notes,
and the securities of the guaranteeing subsidiaries have been pledged to secure
the 12% Senior Notes. See Note 2 of Notes to the Company's Consolidated
Financial Statements. The Senior Notes Indentures limit the Company and the
guaranteeing subsidiaries with respect to asset sales, restricted payments, the
incurrence of additional debt, the issuance of preferred stock, liens, sale and
leaseback transactions, lines of business, dividend and certain other payments,
mergers or consolidations, and transactions with affiliates. The Company must
repurchase the Senior Notes upon a change of control, the sale of certain assets
or failure to maintain a specified ratio of assets to debt.
 
  FINANCIAL FLEXIBILITY AND LIQUIDITY
 
     The Company had working capital of $0.3 million at June 30, 1996. The
Company had unused Revolving Credit Facility commitments of $75 million, of
which $10 million was outstanding as of September 30, 1996. The total facility
size has been set at $125 million subject to certain borrowing base and Senior
Notes Indentures limitations. This facility provides for interest at the Union
Bank reference rate (8.25% at
 
                                       24
<PAGE>   25
 
September 30, 1996), or at the option of the Company the Eurodollar rate plus
1.375% to 1.875%, depending on the ratio of the amount outstanding to the
borrowing base. Although the Senior Notes Indentures contain various
restrictions on additional indebtedness, based on asset values as of June 30,
1996 the Company estimates it could borrow up to $106 million within these
restrictions.
 
     The Company also maintains a limited resource bank facility with an amount
outstanding of $12.9 million as of June 30, 1996 secured by producing oil and
gas properties owned by the Company's wholly-owned subsidiary CGDC. This
facility provides for interest at the Union Bank reference rate (8.25% at
September 30, 1996) or, at the option of the Company, the Eurodollar rate plus
1.875%. The facility has not been guaranteed by the Company or any of its other
subsidiaries and is recourse only to the assets of CGDC. CGDC used proceeds
borrowed under this facility to acquire producing oil and gas properties from
Chesapeake Exploration Limited Partnership ("CEX"), another subsidiary of the
Company. The terms of the facility prohibit the payment of dividends by CGDC.
 
     Debt ratings for the Senior Notes are Ba3 by Moody's Investors Service and
B+ by Standard & Poor's Corporation. Both Moody's and S&P upgraded their ratings
during the year. The Company's long-term debt represented 60% of total capital
at June 30, 1996. At June 30, 1996, on a pro forma basis after giving effect to
the completion of this Offering and the application of the net proceeds
therefrom, the Company's debt to total capital ratio would have been
approximately 35%. Over time, the Company seeks to achieve an investment grade
senior debt rating.
 
  OPERATING CASH FLOWS
 
     Cash provided by operating activities was $121 million in fiscal 1996, as
compared to $54.7 million in 1995, and $19.4 million in 1994. Operating cash
flows for 1996 included enhanced earnings primarily as a result of increased oil
and gas production. Other major factors affecting cash flows for 1996, 1995 and
1994 were increases in non-cash charges and cash flows provided by changes in
the components of assets and liabilities. A portion of the proceeds of the
Offering and cash provided by operating activities are expected to be the
primary sources for meeting forecasted cash requirements in 1997.
 
  INVESTING CASH FLOWS
 
     Significantly higher cash was used in fiscal 1996 for development,
exploration and acquisition of oil and gas properties as compared to fiscal 1995
and 1994. Approximately $336 million was expended by the Company in 1996 (net of
proceeds from sale of leasehold and equipment, and from providing certain
oilfield services), as compared to $106 million in 1995, an increase of $230
million, or approximately 216%. In fiscal 1994 the Company expended $27 million
(net of proceeds from sales of leasehold, equipment and other) for development
and exploration activities. Net cash proceeds received by the Company for sales
of oil and gas equipment, leasehold and other services decreased to
approximately $11 million in fiscal 1996 as compared to $15 million in 1995. In
fiscal 1996, other property and equipment additions were $8.8 million, primarily
as a result of the purchase of additional office buildings in its headquarters
complex in Oklahoma City.
 
     The Company's capital spending is largely discretionary. The Company has
established a fiscal 1997 capital expenditure budget of approximately $300
million, of which $80 million is budgeted to fund drilling and completion
requirements for the development of a portion of its proved undeveloped reserves
during fiscal 1997. The Company expects to spend approximately $155 million for
the development of its unproved reserves, $10 million for seismic programs and
$55 million for acreage acquisition and other corporate purposes. Based on
recent drilling results, the Company is evaluating an expansion of its capital
budget for fiscal 1997 and fiscal 1998. Management believes that the Company's
internally generated cash flow, the proceeds from the Offering and its Revolving
Credit Facility should be sufficient to fund its operating activities, budgeted
capital expenditures and its debt service obligations in fiscal 1997 and 1998.
The discretionary nature of nearly all of the Company's capital spending permits
the Company to make adjustments to its budget based upon factors such as oil and
gas pricing, exploration and development drilling results, and the continued
availability of internally generated or external capital resources.

LEGAL PROCEEDINGS
 
     On October 15, 1996, Union Pacific Resources Company ("UPRC") filed suit
against the Company in the United States District Court for the Northern
District of Texas alleging (a) infringement of UPRC's claimed patent (the "UPRC
Patent") for an invention involving a method of maintaining a bore hole in a
stratigraphic zone during drilling, and (b) tortious interference with contracts
between UPRC and a third party vendor (the "Vendor") regarding the
confidentiality of proprietary information of UPRC. UPRC is seeking injunctive
relief, damages of an unspecified amount, including actual, enhanced,
consequential and punitive damages, interest, costs and attorney's fees. The
Company believes that it has meritorious defenses to UPRC's allegations,
including, without limitation, the Company's belief that the UPRC Patent is
invalid. The Company will vigorously defend the lawsuit. No assurance can be
given as to the outcome of the matter or the ultimate impact on the Company of
any damages (which could be substantial) that may be awarded to UPRC because
litigation is inherently uncertain.
 
     Since February 1994, the Vendor has assisted the Company in the analysis of
horizontal drilling data. In May 1994, the UPRC Patent was issued to UPRC by the
U.S. Patent Office and, in August 1995, UPRC advised the Company that the
Vendor's services infringed the UPRC Patent. Promptly following receipt of such
notification, the Company retained patent counsel who, in December 1995,
provided the Company with a legal opinion that the UPRC Patent was invalid.
 
     In September 1995, litigation to which the Company was not a party
commenced between UPRC and the Vendor. On October 11, 1996, the litigation was
settled with an agreed judgment reciting the validity of the UPRC Patent and
finding that the services provided by the Vendor violated the UPRC Patent. The
agreed judgment enjoined the Vendor from further infringement of the UPRC Patent
and use of UPRC's trade secrets.
 
     By letter dated October 16, 1996, the Vendor advised the Company that the
Vendor expected to offer alternative services in the near future which,
according to the Vendor, will not violate the Vendor's settlement agreement with
UPRC and will not infringe the UPRC Patent. The Vendor also advised the Company
that UPRC had agreed to permit the Vendor to complete work in progress which,
under the agreed judgment, had been found to infringe the UPRC Patent. The
Company believes that alternative services offered by the Vendor and other third
party vendors will allow the Company to continue its horizontal drilling program
without material interruption.

                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of the Company consists of 45,000,000 shares
of Common Stock, par value $.10 per share, and 2,000,000 shares of Preferred
Stock, par value of $.01 per share ("Preferred Stock"). As of October 25, 1996
the issued and outstanding capital stock of the Company consisted of 30,128,321
shares of Common Stock. No shares of Preferred Stock are currently outstanding.
Also, an additional 4,110,834 shares of Common Stock were reserved for issuance
upon the exercise of options granted and which may be granted under the
Company's stock option plans.
 
     The Company's Board of Directors has approved and, at the Company's 1996
annual meeting, will submit to its shareholders for approval a proposal that the
Company reincorporate in the State of Oklahoma. The primary reason for the
reincorporation is to save approximately $150,000 in annual franchise taxes
while retaining corporate governance laws similar to those of Delaware. The
reincorporation will be accomplished by merging the Company into its
newly-formed Oklahoma subsidiary, Chesapeake Oklahoma Corporation ("Chesapeake
Oklahoma"). Upon consummation of the merger, the name of Chesapeake Oklahoma
will become Chesapeake Energy Corporation. The authorized capital stock of
Chesapeake Oklahoma is (and the authorized capital stock of the Company upon the
consummation of the merger will be) 100,000,000 shares of common stock, par
value $.01 per share, and 10,000,000 shares of preferred stock, par value $.01
per share. The issued and outstanding shares and the shares reserved for
issuance upon the exercise of options which have been and may be granted under
the Company's stock option plans will remain unchanged. If approved by
shareholders, the reincorporation will be effective on December 31, 1996.
Purchasers of Common Stock in the Offering will not be shareholders of record
entitled to vote at the 1996 annual meeting.
 
     The following description of certain matters relating to the capital stock
of the Company is a summary and is qualified in its entirety by the provisions
of the Company's Certificate of Incorporation and Bylaws, which are incorporated
by reference as exhibits to the Registration Statement of which this Prospectus
is a part. The Certificate of Incorporation and the Bylaws of Chesapeake
Oklahoma are substantially the same as the Certificate of Incorporation
("Certificate") and Bylaws of the Company. Also the Oklahoma General Corporation
Act (the "Oklahoma Act") was adopted from the Delaware General Corporation Law
(the "Delaware Law") and the rights and obligations of stockholders of the
Company will be virtually unchanged. References to the Certificate and Bylaws of
the Company include references to the Certificate and Bylaws of Chesapeake
Oklahoma after the reincorporation.
 
COMMON STOCK
 
     The holders of Common Stock are entitled to one vote per share on all
matters submitted to a vote of stockholders of the Company. In addition, such
holders are entitled to receive ratably such dividends, if any, as may be
declared from time to time by the Board of Directors out of funds legally
available therefor, subject to the payment of preferential dividends with
respect to any Preferred Stock that from time to time may be outstanding. In the
event of the dissolution, liquidation or winding-up of the Company, the holders
of Common Stock are entitled to share ratably in all assets remaining after
payment of all liabilities of the Company and subject to the prior distribution
rights of the holders of any Preferred Stock that may be outstanding at that
time. The holders of Common Stock do not have cumulative voting rights or
preemptive or other rights to acquire or subscribe for additional, unissued or
treasury shares. All outstanding shares of Common Stock are fully paid and
nonassessable.
 
PREFERRED STOCK
 
     The Company has an authorized class of Preferred Stock consisting of
2,000,000 shares, none of which is issued and outstanding. The Board of
Directors is authorized, subject to any limitations prescribed by law, without
further stockholder approval, to issue shares of Preferred Stock from time to
time in one or more new series as from time to time designated. Each such series
of Preferred Stock would have such number of shares, designations, preferences,
voting powers, qualifications and special or relative rights or privileges as
shall be determined by the Board of Directors, which may include, among others,
dividend rights, voting rights, redemption and sinking fund provisions,
liquidation preferences and conversion rights.
 
                                       30
<PAGE>   31
 
     While providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, and eliminating delays associated
with a stockholder vote on specific issuances, the issuance of Preferred Stock
could adversely affect the voting power of holders of Common Stock and decrease
the likelihood that such holders of Common Stock will receive dividend payments
and payments upon liquidation, and could have the effect of delaying, deferring
or preventing a change in control of the Company.
 
ANTI-TAKEOVER PROVISIONS
 
     The Certificate and Bylaws of the Company, and the Delaware Law and
Oklahoma Act include a number of provisions which may have the effect of
encouraging persons considering unsolicited tender offers or other unilateral
takeover proposals to negotiate with the Board of Directors rather than pursue
non-negotiated takeover attempts. These provisions include a classified board of
directors, authorized blank check preferred stock, restrictions on business
combinations and certain stock repurchases, and the availability of authorized
but unissued Common Stock.
 
  CLASSIFIED BOARD OF DIRECTORS
 
     The Company's Certificate and Bylaws contain provisions for a staggered
board of directors with only one-third of the board standing for election each
year. Directors can only be removed for cause. A staggered board makes it more
difficult for stockholders to change the majority of the directors and instead
promotes a continuity of existing management.
 
  BLANK CHECK PREFERRED STOCK
 
     The Certificate authorizes blank check Preferred Stock. See "-- Preferred
Stock." The Board of Directors can set the voting rights, redemption rights,
conversion rights and other rights relating to such Preferred Stock and could
issue such stock in either a private or public transaction. In some
circumstances, the blank check Preferred Stock could be issued and have the
effect of preventing a merger, tender offer or other takeover attempt which the
Board of Directors opposes.
 
  TAKEOVER STATUTES
 
     Section 203 of the Delaware Law and Section 1090.3 of the Oklahoma Act
generally prevent an "interested stockholder" from engaging in a "business
combination" with a corporation for three years following the date such person
became an interested stockholder, unless (i) prior to the time such person
became an interested stockholder, the board of directors of the corporation
approved the transaction in which the interested stockholder became an
interested stockholder or approved the business combination; (ii) upon
consummation of the transaction that resulted in the interested stockholder
becoming an interested stockholder, the interested stockholder owns at least 85%
of the voting stock of the corporation outstanding at the time the transaction
commenced, excluding stock held by directors who are also officers of the
corporation and stock held by certain employee stock plans; or (iii) on or
subsequent to the time of the transaction in which such person became an
interested stockholder, the business combination is approved by the board of
directors of the corporation and authorized at a meeting of stockholders by the
affirmative vote of the holders of two-thirds of the outstanding voting stock of
the corporation not owned by the interested stockholder.
 
     The statutes define a "business combination" to include (i) any merger or
consolidation involving the corporation and an interested stockholder, (ii) any
sale, transfer, pledge or other disposition involving an interested stockholder
of 10% or more of the assets of the corporation, (iii) subject to certain
exceptions, any transaction which results in the issuance or transfer by the
corporation of any stock of the corporation to an interested stockholder, (iv)
any transaction involving the corporation which has the effect of increasing the
proportionate share of the stock of any class or series of the corporation
beneficially owned by the interested stockholder or (v) the receipt by an
interested stockholder of any loans, guarantees, pledges or other financial
benefits provided by or through the corporation. For purposes of Sections 203 of
the Delaware Law and 1090.3 of the Oklahoma Act, the term "corporation" also
includes the Company's majority-owned subsidiaries. In addition, the statutes
define an "interested stockholder" as any entity or person beneficially owning
15% or
 
                                       31
<PAGE>   32
 
more of the outstanding voting stock of the corporation and any entity or person
affiliated with or controlling or controlled by such entity or person.
 
  STOCK PURCHASE PROVISIONS
 
     The Certificate includes a provision which requires the affirmative vote of
two-thirds of the outstanding shares of capital stock entitled to vote generally
in the election of directors held by persons who are not interested stockholders
(as defined) to approve the repurchase of any equity securities of the Company
from any interested stockholder, unless such repurchase is either (i) made on
the same terms offered to all holders of the same securities or (ii) made on the
open market and not the result of a privately negotiated transaction.
 
STOCKHOLDER ACTION
 
     With respect to any act or action required of or by the holders of the
Common Stock, the affirmative vote of a majority of the shares of Common Stock
present in person or represented by proxy at a meeting and entitled to vote
thereon is sufficient to authorize, affirm, ratify or consent to such act or
actions, except as otherwise provided by law or in the Charter. Both the
Delaware Law and the Oklahoma Act require the approval of the holders of a
majority of the outstanding stock entitled to vote for certain extraordinary
corporate transactions, such as a merger, sale of substantially all assets,
dissolution or amendment of the Certificate. The Certificate provides for a vote
of the holders of two-thirds of the issued and outstanding stock having voting
power, voting as a single class, to amend, repeal or adopt any provision
inconsistent with the provisions of the Certificate limiting director liability
and stock repurchases by the Company, and providing for staggered terms of
directors and indemnity for directors. Such vote is also required for
stockholders to amend, repeal or adopt any provision of the Bylaws.
 
     Stockholders may take actions without the holding of a meeting by written
consent or consents signed by the holders of a sufficient number of shares to
approve the transaction had all of the outstanding shares of the capital stock
of the Company entitled to vote thereon been present at a meeting. Messrs.
McClendon and Ward and the other directors and executive officers as a group
beneficially own approximately 42% of the outstanding Common Stock prior to the
Offering and 37% after the Offering. Pursuant to the rules and regulations of
the Commission, if stockholder action is taken by written consent, the Company
will be required to send each stockholder entitled to vote on the matter acted
on, but whose consent was not solicited, an information statement containing
information substantially similar to that which would have been contained in a
proxy statement.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Common Stock is Liberty Bank and
Trust Company of Oklahoma City, N.A.

     The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Common Stock are
subject to the approval of certain legal matters by counsel and to certain other
conditions. If any of the shares of Common Stock are purchased by the
Underwriters pursuant to the Underwriting Agreement, all such shares of Common
Stock (other than the shares of Common Stock covered by the over-allotment
option described below) must be so purchased.
 
     The Company has been advised by the Representatives that the Underwriters
propose to offer the Common Stock to the public initially at the price to the
public set forth on the cover page of this Prospectus and to certain dealers
(who may include the Underwriters) at such price less a concession not to exceed
$1.80 per share. The Underwriters may allow, and such dealers may reallow, a
discount not in excess of $0.10 per share to any other Underwriter and certain
other dealers.
 
     The Company has granted to the Underwriters an option to purchase up to
486,000 additional shares of Common Stock at the public offering price set forth
on the cover page hereof less underwriting discounts and commissions, solely to
cover over-allotments. Such option may be exercised at any time until 30 days
after the date of this Prospectus. To the extent that the Underwriters exercise
such option, each of the Underwriters will be committed, subject to certain
conditions, to purchase a number of option shares proportionate to such
Underwriter's initial commitment as indicated in the preceding table.
 
     The Company, subject to certain exceptions, has agreed not to offer, sell
or otherwise dispose of any shares of Common Stock, or any shares exercisable
for or convertible into shares of Common Stock, prior to the expiration of 90
days from the date of this Prospectus, without the prior written consent of
Donaldson, Lufkin & Jenrette Securities Corporation on behalf of the
Underwriters.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, as amended
(the "Securities Act") or to contribute to payments that the Underwriters may be
required to make in respect thereof.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
of Chesapeake Energy Corporation
 
     We have audited the accompanying consolidated balance sheet of Chesapeake
Energy Corporation and its subsidiaries as of June 30, 1996, and the related
consolidated statements of income, stockholders' equity and cash flows for the
year then ended. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Chesapeake
Energy Corporation and its subsidiaries as of June 30, 1996, and the
consolidated results of their operations and their cash flows for the year then
ended in conformity with generally accepted accounting principles.

audits provide a reasonable basis for the opinion expressed above. We have not
audited the consolidated financial statements of Chesapeake Energy Corporation

SUPPLEMENTAL SCHEDULE OF NON-CASH INVESTING AND FINANCING ACTIVITIES:
 
     The Company has a financing arrangement with a vendor to supply certain oil
and gas equipment inventory. The total amounts owed at June 30, 1996, 1995 and
1994 were $3,156,000, $6,513,000 and $5,952,000, respectively. No cash
consideration is exchanged for inventory under this financing arrangement until
actual draws on the inventory are made.
 
     In fiscal 1996 and 1995, the Company recognized income tax benefits of
$7,950,000 and $1,229,000, respectively, related to the disposition of stock
options by directors and employees of the Company. The tax benefits were
recorded as an adjustment to deferred income taxes and paid-in capital.
 
     Proceeds from the issuances of $90 million of 10.5% Senior Notes in May
1995 and $120 million of 9.125% Senior Notes in April 1996 are net of $2.7
million and $3.9 million, respectively, in offering fees and expenses which were
deducted from the actual cash received.
 
     On March 31, 1994, the Company issued 8,000 units (see Note 2) to Trust
Company of the West ("TCW") primarily in consideration for the surrender of
576,923 shares of the Company's 9% convertible preferred stock, including its
rights to dividends, warrants to purchase Common Stock and an overriding royalty
interest.
 
     In February 1994, pending litigation was settled pursuant to an agreement
requiring COI to pay $1.25 million, of which $250,000 plus interest was paid in
July 1994, and the balance of which was paid in June 1995.
 
     The accompanying notes are an integral part of these consolidated financial
statements.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The accompanying consolidated financial statements of Chesapeake Energy
Corporation (the "Company" or "Parent") include the accounts of Chesapeake
Operating, Inc. ("COI"), Chesapeake Exploration Limited Partnership ("CEX"), a
limited partnership, Chesapeake Gas Development Corporation ("CGDC"), Chesapeake
Energy Marketing, Inc. ("CEMI"), Lindsay Oil Field Supply, Inc. ("LOF"), Sander
Trucking Company, Inc. ("STCO") and subsidiaries of those entities. All
significant intercompany accounts and transactions have been eliminated.
 
     In December 1995, the Company entered into the gas marketing business by
acquiring all of the outstanding stock of an Oklahoma City-based natural gas
marketing company for total consideration of $725,000. This subsidiary was
subsequently named CEMI. CEMI provides natural gas marketing services including
commodity price structuring, contract administration and nomination services for
the Company, its partners and other natural gas producers in the geographical
areas in which the Company is active.
 
  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.
 
  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. The
Company's oil and gas reserves are estimated annually by independent petroleum
engineers. The average composite rates used for depreciation, depletion and
amortization were $0.85, $0.80 and $0.80 per equivalent Mcf in 1996, 1995, and
1994, 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. Unamortized costs as reduced by related deferred taxes are subject
to a ceiling which limits such amounts to the estimated present value of oil and
gas reserves, reduced by operating expenses, future development costs and income
taxes. The costs of unproved properties are excluded from amortization until the
properties are evaluated.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     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 $35 million, subject
to adjustment for activity after the effective date of January 1, 1996. The
properties are located in the Knox and Golden Trend fields of southern Oklahoma,
most of which are operated by the Company.
 
  Other Property and Equipment
 
     Other property and equipment primarily consists of vehicles, 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 over the
estimated useful lives of the assets, which range from three to 30 years.
 
  Leases
 
     Included in other property and equipment in the consolidated balance sheets
is computer equipment and software held under capital leases. Minimum lease
payments under these capital leases and other operating leases are as follows:

</TABLE>
 
  Capitalized Interest
 
     During fiscal 1996, 1995 and 1994, interest of approximately $6,428,000,
$1,574,000 and $356,000 was capitalized on significant investments in unproved
properties that are not being currently depreciated, depleted, or amortized and
on which exploration or development activities are in progress.
 
  Service Operations
 
     Certain subsidiaries of the Company performed contractual services on wells
the Company operates 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 statements of income include amounts derived from
certain of the contractual services provided. The Company's economic interest in
its oil and gas properties is 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 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
the industry. The Company sold its
 
                                      F-10

                 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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 recorded as a
reduction in the Company's investment in Peak and will be amortized to income
over the estimated useful lives of the Peak assets. The Company's investment in
Peak will be accounted for using the equity method.
 
  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 Per Share
 
     Primary and fully diluted earnings per share for all periods have been
computed based upon the weighted average number of shares of Common Stock
outstanding after giving retroactive effect to all stock splits and the issuance
of common stock equivalents when their effect is dilutive. Dilutive options or
warrants which are issued during a period or which expire or are cancelled
during a period are reflected in both primary and fully diluted earnings per
share computations for the time they were outstanding during the period being
reported upon.
 
  Gas Imbalances
 
     The Company follows the "sales method" of accounting for its oil and gas
revenue whereby the Company recognizes sales revenue on all oil or 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 reserves on the
underlying properties. The Company's net imbalance positions at June 30, 1996
and 1995 were not material.
 
  Hedging
 
     The Company periodically uses certain instruments to hedge its exposure to
price fluctuations on oil and natural gas transactions. Recognized gains and
losses on hedge contracts are reported as a component of the related
transaction. Results for hedging transactions are reflected in oil and gas sales
to the extent related to the Company's oil and gas production.
 
  Debt Issue Costs
 
     Other assets relate primarily to debt issue costs associated with the
issuance of the 12% Senior Notes on March 31, 1994, the 10.5% Senior Notes on
May 25, 1995, and the 9.125% Senior Notes on April 9, 1996 (see Note 2). The
remaining unamortized costs on these issuances of Senior Notes at June 30, 1996
totaled $8.7 million and are being amortized over the life of the Senior Notes.
 
  Stock Options
 
     In October 1995, the Financial Accounting Standards Board issued Statement
No. 123 ("SFAS 123"), "Accounting for Stock Based Compensation". As permitted by
SFAS 123, the Company plans to continue to retain its current method of
accounting for stock compensation and adopt the disclosure requirements of this
Statement in fiscal 1997.

  Reclassifications
 
     Certain reclassifications have been made to the consolidated financial
statements for the years ended June 30, 1995 and 1994 to conform to the
presentation used for the June 30, 1996 consolidated financial statements.
 
2. SENIOR NOTES
 
     On April 9, 1996, the Company completed an offering of $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 at
the redemption or make-whole prices set forth in the indenture. 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 completed a private offering of $90 million
principal amount of 10.5% Senior Notes due 2002 ("10.5% Senior Notes"). The
10.5% Senior Notes are redeemable at the option of the Company at any time on or
after June 1, 1999. The Company may also redeem at its option any time prior to
June 1, 1998 up to $30 million of the 10.5% Senior Notes at 110% of the
principal amount thereof with the proceeds of an equity offering. In September
1995, the Company exchanged the 10.5% Senior Notes for substantially identical
notes in a registered exchange offer (also referred to as the "10.5% Senior
Notes").
 
     On March 31, 1994, the Company completed a private offering of 47,500 Units
consisting of an aggregate of $47.5 million principal amount of 12% Senior Notes
due 2001 ("12% Senior Notes") and warrants ("Warrants") to purchase 2,190,937
shares of the Company's Common Stock at an aggregate exercise price of $4,870.
The Warrants were valued at $3 million creating a discount on the 12% Senior
Notes. All of the Warrants were subsequently exercised. In exchange for 8,000
Units, the Company acquired from Trust Company of the West ("TCW") 576,923
shares of the Company's 9% cumulative convertible preferred stock and all rights
to dividends thereon, warrants to purchase 1,404,004 shares of the Company's
Common Stock and 50% of an outstanding overriding royalty interest held by TCW.
The 12% Senior Notes are redeemable at the option of the Company at any time on
or after March 1, 1998 at an initial premium of 106% of the principal amount
thereof, declining to no premium in 2000. The Company is required to redeem
$11,875,000 principal amount of 12% Senior Notes on each of March 1, 1998, 1999
and 2000. In November 1994, the Company exchanged the 12% Senior Notes for
substantially identical notes in a registered exchange offer (also referred to
as the "12% Senior Notes").
 
     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 12% Senior Notes, the 10.5% Senior Notes and the 9.125%
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 Notes): COI, LOF, STCO, Whitmire Dozer
Service, Inc. and CEX (collectively, the "Subsidiary Guarantors"). The only
subsidiaries of the Company that are not Subsidiary Guarantors are CGDC and CEMI
(together, the "Non-Guarantor Subsidiaries"). Each of the Subsidiary Guarantors
is a direct or indirect wholly-owned subsidiary of the Company. The securities
of the Subsidiary Guarantors have been pledged to secure performance of the
Company's obligations under the 12% Senior Notes. The only affiliate securities
constituting a substantial portion of the collateral for the 12% Senior Notes
are the partnership interests in CEX.
 
     The 12%, 10.5% and 9.125% Senior Note Indentures contain certain covenants,
including covenants limiting the Company and the Subsidiary Guarantors 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 Subsidiary Guarantors; mergers or consolidations; and transactions
with affiliates. The Company is also obligated to repurchase 12%,

10.5% and 9.125% Senior Notes if it fails to maintain a specified ratio of
assets to debt and in the event of a change of control or certain asset sales.
 
     The Company's bank credit agreement prohibits any distributions by CEX to
its partners (the Company and COI) if the maturity of any obligations to the
lender has been accelerated. The pledge agreement relating to the 12% Senior
Notes requires that all dividends and distributions from Subsidiary Guarantors
be paid to the collateral agent thereunder upon an event of default under the
12% Senior Notes Indenture. There are no other restrictions on the payment of
cash dividends by Subsidiary Guarantors.
 
     CEX is a limited partnership which is 10% owned by COI, as sole general
partner, and 90% owned directly by the Company, as sole limited partner. CEX
owns 94% and CGDC owns 6% of the Company's producing oil and gas properties,
based on the present value of future net revenue at June 30, 1996 (discounted at
10%).
 
     Set forth below are condensed consolidating financial statements of CEX,
the other Subsidiary Guarantors, all Subsidiary Guarantors combined, the
Non-Guarantor Subsidiaries and the Company. The CEX limited partnership
condensed financial statements were prepared on a separate entity basis as
reflected in the Company's books and records and include all material costs of
doing business as if the partnership were on a stand-alone basis except that
interest is not charged or allocated. No provision has been made for income
taxes because the partnership is not a taxpaying entity. Separate audited
financial statements of each Subsidiary Guarantor, other than CEX, have not been
provided because management has determined that they are not material to
investors.

     In April 1993, CEX entered into an oil and gas reserve-based reducing
revolving credit facility (the "Revolving Credit Facility") with Union Bank. The
Revolving Credit Facility has been amended from time to

time, most recently in September 1996. Concurrent with the September 1996
amendment, the Company increased the facility size to $125 million and expanded
its bank group with Union Bank remaining as agent.
 
     The maturity date of the Revolving Credit Facility is April 30, 2001. The
facility provides for interest at the Union Bank reference rate (8.25% at June
30, 1996) or, at the option of the Company the Eurodollar rate plus 1.375% to
1.875% depending on the ratio of the amount outstanding to the borrowing base.
Borrowings are collateralized by a first priority lien on substantially all of
CEX's proved producing reserves, and are unconditionally guaranteed by the
Company. At June 30, 1996 and 1995 there was $0 and $10,000 outstanding under
the Revolving Credit Facility, respectively.
 
     The amount of credit available at any time under the Revolving Credit
Facility is the lesser of the commitment amount or the borrowing base. The
borrowing base is reduced each month by a specified amount. Both the borrowing
base and the monthly reduction amount are redetermined by Union Bank each May 1
and November 1 and may be redetermined at any other time upon the request of CEX
or Union Bank. To the extent the amount outstanding at any time exceeds the
borrowing base, CEX must reduce the amount outstanding or add additional
collateral. At June 30, 1996, the commitment amount and the borrowing base under
the Revolving Credit Facility were $35 million, and the monthly reduction amount
was $700,000. The Revolving Credit Facility was amended in September 1996 to
provide for a borrowing base and a commitment amount of $75 million, with a
monthly reduction amount of $1,750,000. The Revolving Credit Facility contains
customary financial covenants, limitations on indebtedness and liabilities,
liens, prepayments of other indebtedness (including the 12%, 10.5% and 9.125%
Senior Notes) and loans, investments and guarantees by the Company and prohibits
the payment of dividends on the Company's Common Stock.
 
     The Company's wholly-owned subsidiary, CGDC, has a credit facility with
Union Bank (the "Term Credit Facility"), with an outstanding balance of $12.9
million at June 30, 1996. Collateral for the Term Credit Facility is limited to
CGDC's producing oil and gas properties. The Term Credit Facility has not been
guaranteed by the Company or any of its other subsidiaries and is recourse only
to the assets of CGDC. CGDC acquired producing oil and gas properties from CEX
in December 1994, June 1995 and December 1995 in exchange for $5.5 million, $6
million and $5.3 million in cash, respectively, using proceeds borrowed under
this facility. CGDC has not guaranteed the payment of the Company's 12%, 10.5%
or 9.125% Senior Notes, nor has the capital stock of CGDC been pledged as
collateral for such indebtedness. The terms of the Term Credit Facility prohibit
the payment of dividends by CGDC.
 
4. CONTINGENCIES AND COMMITMENTS
 
     The Company is currently involved in various 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 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 June 30, 1997 through June 30, 1998.
 
     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 environmental issues or claims.

     At June 30, 1996, the Company had regular tax net operating loss
carryforwards of approximately $140 million and alternative minimum tax net
operating loss carryforwards of approximately $15 million. These loss
carryforward amounts will expire during the years 2007 through 2011. The Company
also had a percentage depletion carryforward of approximately $2.3 million at
June 30, 1996, 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

the Internal Revenue Service, the Company does not believe that an Ownership
Change has occurred as of June 30, 1996.
 
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 June 30, 1996, 1995 and 1994 the Company had accounts receivable
for these costs of $2.9 million, $4.4 million and $1.7 million, respectively.
 
     During fiscal 1996, 1995 and 1994 the Company incurred legal expenses of
$347,000, $516,000 and $631,000, respectively, for legal services provided by
the law firm of which a director is a member.
 
7. EMPLOYEE BENEFIT PLANS
 
     Effective October 1, 1989, the Company established a 401(K) profit sharing
plan. On December 1, 1993, the Company amended the plan and established the
Chesapeake Energy Savings and Incentive Plan. On January 1, 1996 the Company
amended the plan and established the Chesapeake Energy Corporation Savings and
Incentive Stock Bonus Plan (the "Savings and Incentive Stock Bonus Plan").
Eligible employees may make voluntary contributions to the Savings and Incentive
Stock Bonus Plan which are matched by the Company up to 10% of the employees'
annual salary with the Company's common stock. The amount of employee
contributions is limited as specified in the Savings and Incentive Stock Bonus
Plan. The Company may, at its discretion, make additional contributions to the
Savings and Incentive Stock Bonus Plan. The Company contributed $187,000,
$95,000 and $70,000 to the Savings and Incentive Stock Bonus Plan during the
fiscal years ended June 30, 1996, 1995 and 1994, respectively.

9. STOCKHOLDERS' EQUITY
 
     On April 9, 1996, the Company completed a public offering of 2,475,000
shares of Common Stock at a price of $35.33 per share, resulting in net proceeds

additional 519,750 shares of Common Stock at a price of $35.33 per share,
resulting in additional net proceeds (after offering costs) to the Company of
approximately $17.3 million. The net proceeds from the offering were used to
fund a portion of the Company's exploration and development capital expenditures
and for general corporate purposes.
 
     On March 31, 1994, the Company issued 12% Senior Notes and Warrants for
2,190,937 shares of the Company's Common Stock (see Note 2). The Warrants were
valued at $3.04 million and are recorded as Common Stock Warrants and paid-in
capital on the accompanying consolidated balance sheets. A portion of the 12%
Senior Notes and Warrants were issued to Trust Company of the West in exchange
for preferred stock, warrants to purchase Common Stock and an overriding royalty
interest.
 
     A 1.8-for-1 stock split of the Common Stock in January 1993, a 2-for-1
stock split of the Common Stock in December 1994, and 3-for-2 stock splits of
the Common Stock in December 1995 and June 1996 have been given retroactive
effect in these financial statements.
 
  Stock Option Plans

     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 fiscal 1996 and 1995, $7,950,000 and $1,229,000 was recorded as an
adjustment 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 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 counter-parties and to basis risk.
 
 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 swap
arrangements that establish an index-related price above which the Company pays
the hedging partner and below which the Company is paid by the hedging partner,
the purchase of index-related puts that provide for a "floor" price to the
Company to be paid by the counter-party to the extent the price of the commodity
is below the contracted floor, and basis protection swaps.
 
     As of June 30, 1996, the Company had established NYMEX-based crude oil swap
agreements for 1,000 Bbl per day for July 1, 1996 through August 31, 1996 at an
average price of $17.85 per Bbl. The counter-party has the option exercisable
monthly for an additional 1,000 Bbl per day for the period July 1, 1996 through
December 31, 1996 to cause a swap if the price exceeds an average $17.74 per
Bbl. The actual settlements for July and August resulted in a $0.5 million
payment to the counter-party. The Company estimates, based on NYMEX prices as of
August 30, 1996, that the effect of the September through December hedges would
be a $0.4 million payment to the counter-party.
 
     The Company has purchased Houston Ship Channel put options which guarantee
the Company an average floor price of $2.21/Mmbtu for 20,000 Mmbtu per day for
the period of November 1, 1996 through February 28, 1997. The average cost of
these puts was $0.14 per Mmbtu.
 
     As of June 30, 1996, the Company had NYMEX-based natural gas swaps and
NYMEX/Houston Ship Channel Basis swaps for the months of July through October
1996. These transactions resulted in payments to

the Company's counter-party of approximately $2 million for the month of July
1996 and $1.5 million for the month of August 1996. The Company estimates, based
on NYMEX prices as of August 30, 1996, that the effect of the September and
October hedges would be a $0.2 million payment to the counter-party.
 
  Concentration of Credit Risk
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of 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 not considered investment
grade, unless the credit risk can otherwise be mitigated.
 
  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
June 30, 1996 and 1995 was $255.6 million and $135.2 million, respectively,
compared to approximate fair values of $261.2 million and $137.8 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.

     Unproved properties not subject to amortization at June 30, 1996 and 1995,
consist mainly of lease acquisition costs. The Company capitalized approximately
$6,428,000 and $1,574,000 of interest during the years ended June 30, 1996 and
1995 on significant investments in unproved properties that are not being
currently depreciated, depleted, or amortized and on which exploration or
development activities are in progress. 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.

  Oil and Gas Reserve Quantities (unaudited)
 
     The reserve information presented below is based upon reports prepared by
the independent petroleum engineering firm of Williamson Petroleum Consultants,
Inc. ("Williamson") as of June 30, 1996, 1995 and 1994 and the Company's
petroleum engineers as of June 30, 1996 and 1995. The reserves evaluated
internally by the Company constituted approximately 0.6% and 0.5% of total
proved reserves as of June 30, 1996 and 1995, respectively. 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, 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.
 
     Presented below is a summary of changes in estimated reserves of the
Company based upon the reports prepared by Williamson for 1996, 1995 and 1994,

     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 $35 million, subject
to adjustment for activity after the effective date of January 1, 1996. The
properties are located in the Knox and Golden Trend fields of southern Oklahoma,
most of which are operated by the Company.
 
     In October 1993, the Company entered into a joint development agreement
covering a 20,000 gross acre development area in the Fayette County portion of
the Giddings Field in southern Texas. The Company's ownership interests in the
proved undeveloped properties covered by the joint development agreement were
significantly less than those used in the June 30, 1993 reserve report. The
impact of the reduced ownership percentages is reflected as sales of reserves in
place in fiscal 1994 in the preceding table.
 
  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 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:

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the General Partner and Limited Partner of
Chesapeake Exploration Limited Partnership
 
     We have audited the accompanying balance sheet of Chesapeake Exploration
Limited Partnership ("CEX") as of June 30, 1996, and the related consolidated
statements of income, partners' capital and cash flows for the year then ended.
These financial statements are the responsibility of the CEX management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of CEX as of June 30, 1996, and
the results of its operations and its cash flows for the year then ended in
conformity with generally accepted accounting principles.
 
     As more fully described in Note 1, CEX is a limited partnership owned by
Chesapeake Energy Corporation ("CEC") and Chesapeake Operating, Inc. ("COI").
CEX has no employees and it is dependent on the financial resources of CEC and
COI as well as being dependent on management by COI. Accordingly, CEX has
significant transactions with CEC and COI which are disclosed in Note 4. The
financial statements of CEX should be read in conjunction with the consolidated
financial statements of CEC.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the General Partner and Limited Partner of
Chesapeake Exploration Limited Partnership
 
     In our opinion, the balance sheet and the related statements of income, of
partners' capital and of cash flows as of and for each of the two years in the
period ended June 30, 1995 present fairly, in all material respects, the
financial position, results of operations and cash flows of Chesapeake
Exploration Limited Partnership ("CEX" formerly Chesapeake Exploration Company)
as of and for each of the two years in the period ended June 30, 1995, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of CEX's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with generally accepted
auditing standards which require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above. We have not
audited the financial statements of CEX for any period subsequent to June 30,
1995.
 
     As more fully described in Note 1, CEX is a limited partnership owned by
Chesapeake Energy Corporation ("CEC") and Chesapeake Operating, Inc. ("COI").
CEX has no employees and it is dependent on the financial resources of CEC and
COI as well as being dependent on management by COI. Accordingly, CEX has
significant transactions with CEC and COI which are disclosed in Note 4. The
financial statements of CEX should be read in conjunction with the consolidated
financial statements of CEC.

SUPPLEMENTAL SCHEDULE OF NON-CASH INVESTING AND FINANCING ACTIVITIES:
 
     During the three years ended June 30, 1996, CEX had non-cash intercompany
transactions with the Company consisting primarily of allocated general and
administrative expenses. In fiscal 1996 and 1995, the difference between the net
book value and the proceeds from the sale of oil and gas properties sold to CGDC
of $782,000 and $2,852,000, respectively, resulted in a non-cash transfer.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Chesapeake Exploration Limited Partnership, an Oklahoma limited partnership
("CEX"), was formed on December 27, 1994 and acquired Chesapeake Exploration
Company ("Exploration") by merger on such date. Exploration was a general
partnership which was 10% owned by Chesapeake Operating, Inc. ("COI") and 90%
owned by Chesapeake Energy Corporation ("CEC" or the "Company"). CEC owns 100%
of the Common Stock of COI. CEX is 10% owned by COI as the sole general partner,
and 90% owned directly by the Company, as the sole limited partner.
 
     Effective December 31, 1994, COI transferred to CEX all of the Company's
undeveloped leasehold acreage, thereby formalizing their prior economic
arrangement. Historically, COI had transferred undeveloped leasehold acreage to
CEX on a property-by-property basis as drilling commenced. CEX also owns
substantially all of the Company's proved developed oil and gas properties.
Accordingly, the financial statements of CEX include costs related to proved
undeveloped properties and unevaluated properties, as well as proved producing
properties. The change in partnership structure and the transfer of undeveloped
leasehold by COI to CEX have been accounted for as a reorganization of entities
under common control in a manner similar to a pooling-of-interests.
 
     The CEX financial statements were prepared on a separate entity basis as
reflected in the Company's books and records and include all material costs of
doing business as if the partnership were on a stand-alone basis, except that
interest is not charged on intercompany accounts, or allocated.
 
     Capital is provided by advances from CEC and COI, and to a lesser extent
directly by CEX's bank credit facilities.
 
     These financial statements should be read in conjunction with CEC's
consolidated financial statements.
 
  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 date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.
 
  Oil and Gas Properties
 
     CEC, and therefore CEX, follows the full cost method of accounting under
which all costs associated with property acquisition, exploration and
development activities are capitalized. CEX capitalizes internal costs that can
be directly identified with its acquisition, exploration and development
activities. Such costs do not include any costs related to production, general
corporate overhead or similar activities (see Note 7). Capitalized costs are
amortized on a composite unit-of-production method based on proved oil and gas
reserves. CEX's oil and gas reserves are estimated annually by independent
petroleum engineers. The average composite rates used for depreciation,
depletion and amortization were $.85, $.80 and $.80 per equivalent Mcf in 1996,
1995 and 1994, 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. Unamortized costs, as reduced by related deferred taxes, are subject
to a ceiling which limits such amounts to the estimated present value of oil and
gas reserves, reduced by operating expenses, future development costs and income
taxes. The costs of unproved properties are excluded from amortization until the
properties are evaluated.

         (A WHOLLY-OWNED PARTNERSHIP OF CHESAPEAKE ENERGY CORPORATION)
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     On April 30, 1996, CEX 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 $35 million, subject
to adjustment for activity after the effective date of January 1, 1996. The
properties are located in the Knox and Golden Trend fields of southern Oklahoma,
most of which are operated by the Company.
 
  Capitalized Interest
 
     During fiscal 1996, 1995 and 1994, interest of approximately $6,428,000,
$1,574,000 and $356,000 was capitalized on significant investments in unproved
properties that are not being currently depreciated, depleted, or amortized and
on which exploration or development activities are in progress.
 
  Intercompany Transactions
 
     COI, as operator of the majority of CEX's producing properties, bills CEX,
as non-operator, on a monthly basis for services performed as operator pursuant
to a standard operating agreement which is common in the industry. Expenses
related to the operations of CEX are recorded via such joint interest billings
and via intercompany expense allocations to CEX by COI. CEX has no employees. In
the CEC consolidated group, COI employs all management personnel and employees,
except for employees of the service company subsidiaries, and the preponderance
of general and administrative expenses are reflected in the financial records of
COI. COI allocates a portion of its general and administrative expenses to CEX
each period. This allocation is based on a per well charge at a rate common in
the industry plus an estimate of time spent on CEX activities by officers and
employees of COI.
 
     CEC makes advances to CEX as needed. Certain of CEC's service subsidiaries
perform contractual services on CEX's wells for third parties. These
subsidiaries bill COI, as operator, and COI in turn bills CEX through monthly
joint interest billings in accordance with the terms of the standard operating
agreement.
 
     It is CEC's policy not to demand payment of intercompany accounts. Interest
is not allocated by the Company, nor is interest charged on intercompany
accounts. CEC may, at its discretion, but it is not required to, contribute
intercompany accounts to capital.
 
  Income Taxes
 
     CEX is a partnership and, accordingly, its taxable income or loss is
allocated to the limited partner and the general partner and is ultimately
included in CEC's consolidated tax returns.
 
  Gas Imbalances
 
     CEX follows the "sales method" of accounting for its oil and gas revenue
whereby CEX recognizes sales revenue on all oil or gas sold to its purchasers,
regardless of whether the sales are proportionate to CEX's ownership in the
property. A liability is recognized only to the extent that CEX has a net
imbalance in excess of the reserves on the underlying properties. CEX's net
imbalance positions at June 30, 1996 and 1995 were not material.
 
  Hedging
 
     The Company, on behalf of CEX, periodically uses certain instruments to
hedge its exposure to price fluctuations on oil and natural gas transactions.
Recognized gains and losses on hedge contracts are reported as a component of
the related transaction. Results for hedging transactions are reflected in oil
and gas sales to the extent related to CEX's oil and gas production.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Reclassifications
 
     Certain reclassifications have been made to the CEX financial statements
for the years ended June 30, 1995 and 1994 to conform to the presentation used
for the June 30, 1996 financial statements.
 
2. LONG-TERM DEBT
 
     In April 1993, CEX entered into an oil and gas reserve-based reducing
revolving credit facility (the "Revolving Credit Facility") with Union Bank. The
Revolving Credit Facility has been amended from time to time, most recently in
September 1996. Concurrent with the September 1996 amendment, CEX increased the
facility size to $125 million and expanded its bank group with Union Bank
remaining as agent.
 
     The maturity date of the Revolving Credit Facility is April 30, 2001. The
facility provides for interest at the Union Bank reference rate (8.25% at June
30, 1996) or, at the option of CEX the Eurodollar rate plus 1.375% to 1.875%
depending on the ratio of the amount outstanding to the borrowing base.
Borrowings are collateralized by a first priority lien on substantially all of
CEX's proved producing reserves, and are unconditionally guaranteed by the
Company. At June 30, 1996 and 1995 there was $0 and $10,000 outstanding under
the Revolving Credit Facility, respectively.
 
     The amount of credit available at any time under the Revolving Credit
Facility is the lesser of the commitment amount or the borrowing base. The
borrowing base is reduced each month by a specified amount. Both the borrowing
base and the monthly reduction amount are redetermined by Union Bank each May 1
and November 1 and may be redetermined at any other time upon the request of CEX
or Union Bank. To the extent the amount outstanding at any time exceeds the
borrowing base, CEX must reduce the amount outstanding or add additional
collateral. At June 30, 1996, the commitment amount and the borrowing base under
the Revolving Credit Facility were $35 million, and the monthly reduction amount
was $700,000. The Revolving Credit Facility was amended in September 1996 to
provide for a borrowing base and a commitment amount of $75 million, with a
monthly reduction amount of $1,750,000. The Revolving Credit Facility contains
customary financial covenants, limitations on indebtedness and liabilities,
liens, prepayments of other indebtedness and loans, investments and guarantees
by the Company and prohibits the payment of dividends on the Company's Common
Stock.
 
3. CONTINGENCIES AND COMMITMENTS
 
     CEX has fully and unconditionally guaranteed CEC's obligations under the
$47.5 million principal amount of 12% Senior Notes due 2001, issued March 31,
1994, the $90 million principal amount of 10.5% Senior Notes due 2002, issued
May 25, 1995, and the $120 million principal amount of 9.125% Senior Notes due
2006, issued April 9, 1996. In addition, the CEX partnership interests have been
pledged as collateral under the 12% Senior Notes.
 
4. RELATED PARTY TRANSACTIONS
 
     CEX has significant transactions with COI, CEC, CGDC and other affiliated
companies included in the CEC consolidated group, including:

     Management believes that the loss of any of the above customers would not

6. FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES
 
     The Company, on behalf of CEX, 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
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 counter-parties and to basis risk.
 
  Hedging Activities
 
     Periodically the Company, on behalf of CEX, utilizes hedging strategies to
hedge the price of a portion of its future oil and gas production. These
strategies include swap arrangements that establish an index-related price above
which the Company pays the hedging partner and below which the Company is paid
by the hedging partner, the purchase of index-related puts that provide for a
"floor" price to the Company to be paid by the counter-party to the extent the
price of the commodity is below the contracted floor, and basis protection
swaps.
 
     As of June 30, 1996, the Company had NYMEX-based crude oil swap agreements
for 1,000 Bbl per day for July 1, 1996 through August 31, 1996 at an average
price of $17.85 per Bbl. The counter-party has the option exercisable monthly
for an additional 1,000 Bbl per day for the period July 1, 1996 through December
31, 1996 to cause a swap if the price exceeds an average $17.74 per Bbl. The
actual settlements for July and August resulted in a $0.5 million payment to the
counter-party. The Company estimates, based on NYMEX prices as of August 30,
1996 that the effect of the September through December hedges would be a $0.4
million payment to the counter-party.
 
     The Company has purchased Houston Ship Channel put options which guarantee
the Company an average floor price of $2.21/Mmbtu for 20,000 Mmbtu per day for
the period of November 1, 1996 through February 28, 1997. The average cost of
these puts was $0.14 per Mmbtu.
 
     As of June 30, 1996, the Company had NYMEX-based natural gas swaps and
NYMEX/Houston Ship Channel Basis swaps for the months of July through October
1996. These transactions resulted in payments to

the Company's counter-party of approximately $2 million for the month of July
1996 and $1.5 million for the month of August 1996. The Company estimates, based
on NYMEX prices as of August 30, 1996, that the effect of the September and
October hedges would be a $0.2 million payment to the counter-party.
 
  Concentration of Credit Risk
 
     Financial instruments which potentially subject CEX to concentrations of
credit risk consist principally of trade receivables. CEX'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 CEX'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 not considered investment grade, unless the credit risk can otherwise
be mitigated.
 
  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. Based on the borrowing rates currently available to CEX for bank
loans with similar terms and average maturities, the fair value of long-term
debt approximates the carrying value.

</TABLE>
 
     Unproved properties not subject to amortization at June 30, 1996 and 1995,
consist mainly of lease acquisition costs. CEX capitalized approximately
$6,428,000 and $1,574,000 of interest during the years ended June 30, 1996 and
1995 on significant investments in unproved properties that are not being
currently depreciated, depleted, or amortized and on which exploration or
development activities are in progress. CEX will continue to evaluate its
unevaluated properties; however, the timing of the ultimate evaluation and
disposition of the properties has not been determined.

The information is presented in accordance with regulations prescribed by the
Securities and Exchange Commission. CEX emphasizes that reserve estimates are
inherently imprecise. CEX'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, 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

conditions. Proved developed oil and gas reserves are those expected to be
recovered through existing wells with existing equipment and operating methods.
 
     Presented below is a summary of changes in estimated reserves of CEX based
upon the reports prepared by Williamson for 1996, 1995 and 1994 along with those
prepared by the Company's petroleum engineers for 1996 and 1995.

     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 $35 million, subject
to adjustment for activity after the effective date of January 1, 1996. The
properties are located in the Knox and Golden Trend fields of southern Oklahoma,
most of which are operated by the Company.
 
     In October 1993, CEX entered into a joint development agreement covering a
20,000 gross acre development area in the Fayette County portion of the Giddings
Field in southern Texas. CEX's ownership interests in the proved undeveloped
properties covered by the joint development agreement were significantly less
than those used in the June 30, 1993 reserve report. The impact of the reduced
ownership percentages is reflected as sales of reserves in place in fiscal 1994
in the preceding table.
 
  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. CEX 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 income tax effect of these future cash inflows
will be recognized by CEX's partners. The resulting future net cash flows are
reduced to present value amounts by applying a 10% annual discount factor.
 
     The assumptions used to compute the standardized measure are those
prescribed by the Financial Accounting Standards Board and, as such, do not
necessarily reflect CEX'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 CEX's future net cash flows relating to
proved oil and gas reserves based on the standardized measure prescribed in SFAS
