               AND FINANCIAL RESULTS FOR THE THIRD QUARTER OF 2003

     THIRD QUARTER 2003 NET INCOME AVAILABLE TO COMMON SHAREHOLDERS REACHES
        $82 MILLION ON REVENUE OF $455 MILLION AND PRODUCTION OF 71 BCFE

  COMPANY ALSO REPORTS SIGNIFICANT ADDITIONS TO ITS OIL AND NATURAL GAS HEDGING
   POSITIONS, INCREASES ITS 2003 AND 2004 PRODUCTION FORECASTS ONCE AGAIN AND
          ANNOUNCES $200 MILLION ACQUISITION OF NATURAL GAS PROPERTIES


OKLAHOMA  CITY,  OKLAHOMA,  OCTOBER 30,  2003 -  Chesapeake  Energy  Corporation
(NYSE:CHK) today reported its financial and operating results for the 2003 third
quarter.  For the quarter,  Chesapeake  generated net income available to common
shareholders of $81.9 million ($0.33 per fully diluted common share),  operating
cash flow of $247.7  million  (defined  as cash flow from  operating  activities
before changes in assets and  liabilities) and ebitda of $285.3 million (defined
as income before income taxes, interest expense, and depreciation, depletion and
amortization expense) on revenue of $454.5 million.

The  company's  2003 third quarter net income  available to common  shareholders
included a $0.4 million ($0.00 per share)  after-tax  non-cash  unrealized  gain
recorded in oil and gas sales  resulting from the application of SFAS 133 to the
company's oil and natural gas derivative contracts that do not qualify for hedge
accounting.  In addition,  interest  expense  included a $1.9 million ($0.01 per
share) after-tax non-cash unrealized loss resulting from the application of SFAS
133 to the company's interest rate derivative  contracts that do not qualify for
hedge accounting.

During the third quarter, Chesapeake produced 71.0 billion cubic feet of natural
gas equivalent (bcfe), which compares favorably to the 46.7 bcfe produced in the
2002 third  quarter and the 67.3 produced in the 2003 second  quarter.  The 2003
third quarter's 71.0 bcfe of production was comprised of 63.7 billion cubic feet
of natural  gas (bcf) (90% on a natural  gas  equivalent  basis) and 1.2 million
barrels of oil and natural gas liquids  (mmbo) (10% on a natural gas  equivalent
basis).  Chesapeake's  average  daily  production  rate for the  quarter was 772
million cubic feet of natural gas equivalent production (mmcfe), which consisted
of 692 mmcf of gas and 13,220 barrels of oil and natural gas liquids.

Oil  and  natural  gas  production  in the  2003  third  quarter  increased  52%
year-over-year  from the 2002 third quarter and 5.4%  sequentially from the 2003
second quarter. Of the 3.6 bcfe in sequential production growth during the third
quarter,  34% was internally generated organic drillbit growth. This 1.2 bcfe of
organic  sequential  production  growth  equals a sequential  quarterly  organic
growth rate of just under 2% and an  annualized  organic  growth rate of 8%. The
2003 third  quarter was  Chesapeake's  ninth  consecutive  quarter of sequential
production growth.  During the past nine quarters,  Chesapeake's  production has
increased  81%,  for an average  sequential  quarterly  growth rate of 7% and an
annualized growth rate of 30%.

Average prices realized during the 2003 third quarter (including  realized gains
or losses from oil and gas derivatives, but excluding unrealized gains or losses
on such  derivatives)  were $26.20 per barrel of oil (bo) and $4.92 per thousand
cubic feet of natural gas (mcf),  for a realized gas  equivalent  price of $4.86
per thousand cubic feet of natural gas equivalent (mcfe).  Chesapeake's realized
pricing  differentials to NYMEX during the quarter averaged a negative $2.07 per
bo and a  negative  $0.44  per  mcf.  Realized  gains  or  losses  from  hedging
activities generated a $1.68 loss per bo and a $0.31 gain per mcf.

         CHESAPEAKE UPDATES PRODUCTION FORECASTS AND HEDGING INFORMATION


Chesapeake's  initial 2003 fourth  quarter and updated  full-year  2003 and 2004
forecasts  are attached to this release in a new Outlook  dated October 30, 2003
that is labeled Schedule "A". The company's previous Outlook of July 28, 2003 is
provided as an attachment for comparative reference only and is labeled Schedule
"B".

The October 30 Outlook reflects a projected 2003 fourth quarter production level
of 74.0-74.5 bcfe (807 mmcfe per day) and a projected 2003 full-year  production
volume of 269-270 bcfe (738 mmcfe per day), an increase of 3.7% from the 258-262
bcfe projected in the company's  July 28 Outlook.  The company has now increased
its full-year 2003 production  estimate by approximately 40% since the beginning
of the year. Furthermore, the October 30 Outlook reflects a 7.5% increase in the
company's  projected 2004 production volumes to 297-303 bcfe (822 mmcfe per day)
from the 277-281 bcfe projected in its July 28 Outlook.  Chesapeake believes its
2004 production will exceed 2003's production by at least 11%.

Chesapeake  significantly  increased its hedging  positions during the run-up in
gas prices  that  occurred  earlier  this  month.  During the first two weeks of
October,  the company  hedged 86 bcf of natural gas at an average NYMEX price of
$5.13  per mcf and 700 mbo at an  average  NYMEX  price of  $30.85  per bo.  The
following tables compare projected 2003-2007 oil and natural gas production that
was hedged as of October 30, 2003 versus what was hedged as of July 28, 2003:

view of underlying oil and natural gas supply and demand trends,  Chesapeake may
either  increase or decrease  its  hedging  positions  at any time in the future

         CHESAPEAKE PROVIDES OPERATIONAL UPDATE AND ANNOUNCES AGREEMENT
        TO ACQUIRE $200 MILLION OF NATURAL GAS PROPERTIES IN SOUTH TEXAS

As  evidenced  by  Chesapeake's  strong  organic  production  growth  during the
quarter,  the  company's  drilling  programs  continue to  generate  exceptional
results.  During the  quarter,  Chesapeake  drilled 100 gross  operated (81 net)
wells,  completing 95% of these as successful producers.  The company's operated
rig count during the quarter  averaged 43 rigs compared to 35 and 28 rigs in the
2003 second and first quarters,  respectively.  Today the company's operated rig
count is 43.

In addition to Chesapeake's primary focus area of the Mid-Continent, the company
is also  active in two  secondary  areas:  the  Permian  Basin in west Texas and
eastern New Mexico and the onshore Gulf Coast in Texas and Louisiana.  These two
areas are currently responsible for 11% of Chesapeake's production and 8% of the
company's proved reserves. Although these areas are and will remain secondary in
importance to the company,  Chesapeake periodically finds acquisition candidates
that are attractive in these areas.

The company has  recently  entered  into one such  acquisition  in south  Texas.
Chesapeake  has agreed to acquire $200 million of south Texas natural gas assets
from Houston-based privately-owned Laredo Energy, L.P. and its partners. In this
transaction,  Chesapeake  will  acquire  an  internally  estimated  196  bcfe of
reserves,  of which 108 bcfe are proved and 88 bcfe are  probable  or  possible.
After  allocating $48 million of the $200 million  purchase price to unevaluated
leasehold  for the  probable  and possible  reserves  and  exploratory  acreage,
Chesapeake's  acquisition  cost  per  mcfe of  proved  reserves  will be  $1.41.
Including  future  leasehold and drilling costs for fully developing the proved,
probable and possible reserves, Chesapeake estimates that its all-in acquisition
cost for the 196 bcfe to be acquired will be $1.51 per mcfe.

Current  production from the acquired  properties is  approximately 30 mmcfe per
day. The proved reserves have a  reserves-to-production  index of 10 years,  are
100% natural gas and are 32% proved developed.  Initial lease operating expenses
on the acquired  properties should average $0.09 per mcfe, compared to $0.52 per
mcfe for Chesapeake  during the first three  quarters of 2003 and  approximately
$0.70 per mcfe for the company's  peer group during the first three  quarters of
2003. The company has hedged 100% of the projected Laredo production  volumes at
average  NYMEX prices of $5.76 per mcf for November and December  2003 and $5.20
per mcf for the full-year 2004.

The Laredo  acquisition  is scheduled to close on October 31, 2003.  The company
intends to finance the  acquisition  using cash on hand and borrowings  from its
bank credit  facility.  Chesapeake  expects to repay these  borrowings using its
excess cash flow in the months  ahead and has not yet made a decision on whether
or how to permanently finance the Laredo acquisition.

The Laredo  properties  are  located in the Zapata  County  portion of the south
Texas  Lobo  Trend.  Over the past two  years,  Chesapeake  has  built a growing
operational  presence  in  south  Texas  where  the  company  believes  its deep
drilling,  3-D  seismic  and  tight  sands  expertise  can  provide  competitive
advantages and attractive returns on its invested capital.

                               MANAGEMENT COMMENTS

Aubrey K. McClendon,  Chesapeake's Chief Executive Officer,  commented,  "We are
pleased  to  announce  another  strong  quarter  of  operational  and  financial
performance.  The 2003 third quarter featured delivery of excellent results from
the business strategy set forth below:

o    establishing strong organic production growth from our drilling programs,
o    completing   focused  and   complementary   acquisitions   of  high-margin,
     geographically concentrated natural gas properties,
o    opportunistically hedging high oil and natural gas prices,
o    continuing balance sheet improvement,
o    maintaining low operating costs, and
o    generating high returns on invested capital.

Chesapeake's value-creating financial and operating strategies should enable the
company to continue generating significant increases in shareholder value in the
years ahead."

This  press  release  and the  accompanying  Outlooks  include  "forward-looking
statements"  within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934.  Forward-looking  statements
give our current  expectations  or  forecasts  of future  events.  They  include
estimates of oil and gas reserves,  expected oil and gas  production  and future
expenses, projections of future oil and gas prices, planned capital expenditures
for drilling, leasehold acquisitions and seismic data, and statements concerning
anticipated  cash flow and  liquidity,  business  strategy  and other  plans and
objectives for future operations.  Disclosures  concerning  derivative contracts
and their  estimated  contribution to our future results of operations are based
upon market  information as of a specific date.  These market prices are subject
to significant  volatility.  Although we believe the  expectations and forecasts
reflected in these and other forward-looking  statements are reasonable,  we can
give no assurance they will prove to have been correct.  They can be affected by
inaccurate  assumptions or by known or unknown risks and uncertainties.  Factors
that could cause actual results to differ  materially from expected  results are
described  under "Risk Factors" in Item 1 of our 2002 Form 10-K/A and subsequent
filings with the Securities and Exchange Commission. They include the volatility
of oil and gas prices;  adverse effects our substantial  indebtedness could have
on our operations and future growth; our ability to compete  effectively against
strong  independent oil and gas companies and majors;  the cost and availability
of drilling and production  services;  possible  financial losses as a result of
our commodity price and interest rate risk management activities;  uncertainties
inherent in estimating quantities of oil and gas reserves, including reserves we
acquire,  projecting  future rates of production  and the timing of  development
expenditures;  exposure to potential  liabilities  of acquired  properties;  our
ability to replace  reserves;  the availability of capital;  changes in interest
rates;  and  drilling  and  operating  risks.  We caution you not to place undue
reliance on these forward-looking statements, which speak only as of the date of
this press release, and we undertake no obligation to update this information.

The  Securities  and Exchange  Commission  has  generally  permitted oil and gas
companies,  in their filings with the SEC, to disclose only proved reserves that
a company has demonstrated by actual production or conclusive formation tests to
be economically  and legally  producible  under existing  economic and operating
conditions.  We use the  terms  "probable"  and  "possible"  reserves  or  other
descriptions of volumes of reserves  potentially  recoverable through additional
drilling or recovery  techniques that the SEC's  guidelines may prohibit us from
including  in filings  with the SEC.  These  estimates  are by their nature more
speculative  than estimates of proved  reserves and  accordingly  are subject to
substantially greater risk of being actually realized by the company.

Chesapeake Energy Corporation is one of the six largest independent U.S. natural
gas producers.  Headquartered  in Oklahoma  City,  the company's  operations are
focused  on  exploratory  and  developmental  drilling  and  producing  property
acquisitions  in the  Mid-Continent  region of the United States.  The company's

* Operating  cash flow  represents  net cash  provided by  operating  activities
before  changes  in assets and  liabilities.  Operating  cash flow is  presented
because  management  believes  it is a useful  adjunct to net cash  provided  by
operating  activities  under  accounting  principles  generally  accepted in the
United  States  (GAAP).  Operating  cash flow is widely  accepted as a financial
indicator of an oil and gas company's  ability to generate cash which is used to
internally fund exploration and development activities and to service debt. This
measure is widely  used by  investors  and  rating  agencies  in the  valuation,
comparison,  rating and investment  recommendations  of companies within the oil
and gas  exploration  and  production  industry.  Operating  cash  flow is not a
measure of financial  performance  under GAAP and should not be considered as an
alternative to cash flows from operating,  investing, or financing activities as
an indicator of cash flows, or as a measure of liquidity.

**Ebitda  represents  net income  (loss)  before  income tax expense  (benefit),
interest expense, and depreciation,  depletion and amortization expense.  Ebitda
is presented as a  supplemental  financial  measurement in the evaluation of our
business.  We believe  that it provides  additional  information  regarding  our
ability  to meet our future  debt  service,  capital  expenditures  and  working
capital  requirements.  This  measure  is widely  used by  investors  and rating
agencies in the valuation,  comparison, rating and investment recommendations of
companies.  Ebitda is also a financial measurement that, with certain negotiated
adjustments,  is reported to our banks under our bank credit  facilities  and is
used in our  financial  covenants  under  our  bank  credit  facilities  and the
indentures  governing  our senior  notes.  Ebitda is not a measure of  financial
performance under GAAP. Accordingly, it should not be considered as a substitute
for net  income,  income from  operations,  or cash flow  provided by  operating
activities  prepared  in  accordance  with GAAP.  Ebitda is  reconciled  to cash
provided by operating activities as follows:

As of October 30, 2003, we are using the following key operating  assumptions in
our  projections  for the fourth quarter of 2003,  full year 2003, and full year
2004.

The primary  changes from our July 28, 2003 guidance are in italicized  bold and
are explained as follows:

1)   We  have  updated  the  projected  effects  from  changes  in  our  hedging
     positions.
2)   We have  included our  expectations  for future NYMEX oil and gas prices to
     illustrate   hedging   effects  only.  They  are  not  a  forecast  of  our
     expectations for 2003 or 2004 oil and natural gas prices.
3)   We have  increased our projected  natural gas  production for the full year
     2003 and 2004.
4)   We have included fourth quarter 2003 projections for the first time.



                                                                  Quarter Ending            Year Ending             Year Ending

COMMODITY HEDGING ACTIVITIES

Periodically  the Company  utilizes  hedging  strategies to hedge the price of a
portion of its future oil and gas production. These strategies include:

(i)  For swap instruments, we receive a fixed price for the hedged commodity and
     pay a  floating  market  price,  as  defined  in  each  instrument,  to the
     counterparty.  The fixed-price  payment and the floating-price  payment are
     netted, resulting in a net amount due to or from the counterparty.
(ii) For cap-swaps, Chesapeake receives a fixed price and pays a floating market
     price.  The fixed  price  received  by  Chesapeake  includes  a premium  in
     exchange for a "cap" limiting the counterparty's  exposure. In other words,
     there is no  limit to  Chesapeake's  exposure  but  there is a limit to the
     downside exposure of the counterparty.
(iii)Basis   protection   swaps  are   arrangements   that   guarantee  a  price
     differential  of oil or gas from a  specified  delivery  point.  Chesapeake
     receives  a payment  from the  counterparty  if the price  differential  is
     greater than the stated terms of the contract and pays the  counterparty if
     the price differential is less than the stated terms of the contract.

Commodity markets are volatile,  and as a result,  Chesapeake's hedging activity
is  dynamic.  As market  conditions  warrant,  the Company may elect to settle a
hedging  transaction prior to its scheduled maturity date and, as a result, look
in the gain or loss on the transaction.

Chesapeake  enters into oil and natural gas derivative  transactions in order to
mitigate a portion of its exposure to adverse  market changes in oil and natural
gas  prices.  Accordingly,   associated  gains  or  loses  from  the  derivative
transactions  are reflected as  adjustments  to oil and gas sales.  All realized
gains and losses from oil and natural gas  derivatives  are  included in oil and
gas sales in the month of  related  production.  Pursuant  to SFAS 133,  certain
derivatives do not qualify for  designation as cash flow hedges.  Changes in the
fair  value  of  these  non-qualifying  derivatives  that  occur  prior to their
maturity  (i.e.  because  of  temporary  fluctuations  in  value)  are  reported
currently  in the  consolidated  statement of  operations  as  unrealized  gains
(losses) within oil and gas sales.

Following  provisions  of SFAS  133,  changes  in the fair  value of  derivative
instruments  designated  as  cash  flow  hedges,  to  the  extent  effective  in
offsetting  cash  flows  attributable  to hedged  risk,  are  recorded  in other
comprehensive income until the hedged item is recognized in earnings. Any change
in fair value resulting from  ineffectiveness is recognized currently in oil and
natural gas sales.

The Company currently has in place the following natural gas swaps:

DECEMBER 31, 2004. We have adopted a policy of periodically  providing investors
with guidance on certain factors that affect our future  financial  performance.
As of July 28, 2003, we are using the following key operating assumptions in our
projections for the third quarter of 2003, full year 2003, and full year 2004.

The primary  changes from our June 24, 2003 guidance are in italicized  bold and
are explained as follows:

1)   We  have  updated  the  projected  effects  from  changes  in  our  hedging
     positions.
2)   We have  included our  expectations  for future NYMEX oil and gas prices to
     illustrate   hedging   effects  only,  they  are  not  a  forecast  of  our
     expectations for 2003 oil and natural gas prices.
3)   We have increased our projected oil and natural gas production for the full
     year 2003 and 2004.
4)   We have included third quarter 2003 projections for the first time.

COMMODITY HEDGING ACTIVITIES

Periodically  the Company  utilizes  hedging  strategies to hedge the price of a
portion of its future oil and gas production. These strategies include:

(i)  swap  arrangements  that establish an  index-related  price above which the
     Company  pays the  counterparty  and below which the Company is paid by the
     counterparty,
(ii) the purchase of  index-related  puts that provide for a "floor" price below
     which the  counterparty  pays the  Company the amount by which the price of
     the commodity is below the contracted floor,
(iii)the sale of  index-related  calls that provide for a "ceiling"  price above
     which the Company  pays the  counterparty  the amount by which the price of
     the commodity is above the contracted ceiling,
(iv) basis protection  swaps,  which are  arrangements  that guarantee the price
     differential of oil or gas from a specified delivery point or points, and
(v)  collar  arrangements that establish an index-related  price below which the
     counterparty  pays the  Company  and a separate  index-related  price above
     which the Company pays the counterparty.

Commodity markets are volatile,  and as a result,  Chesapeake's hedging activity
is  dynamic.  As market  conditions  warrant,  the Company may elect to settle a
hedging  transaction  prior to its  scheduled  maturity  date and,  as a result,
realize a gain or loss on the transaction.

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

The  Company   currently  has  in  place  the  following   natural  gas  hedging
arrangements:




                                                                          % Hedged
