ITEM 5.  OTHER EVENTS

     Chesapeake  Energy  Corporation  ("Chesapeake")  issued a Press  Release on
December  4,  2002   announcing   an   agreement  to  acquire  $300  million  of
Mid-Continent  Gas Reserves  from ONEOK,  Inc. The following was included in the
press release:

     OKLAHOMA CITY,  OKLAHOMA,  DECEMBER 4, 2002 - Chesapeake Energy Corporation
(NYSE:CHK)  today  announced  that it has  agreed to  acquire  $300  million  of
Mid-Continent gas assets through an acquisition of a wholly-owned  subsidiary of
Tulsa-based  ONEOK,  Inc.  (NYSE:OKE).  Based  on its  own  internal  engineers'
estimates,  Chesapeake  believes that it will acquire  approximately 200 billion
cubic feet of gas  equivalent  (bcfe) of proved gas  reserves  and  current  gas
production of approximately  47,000 thousand cubic feet of gas equivalent (mcfe)
per   day   in   the   ONEOK   transaction.   The   proved   reserves   have   a
reserves-to-production  index of 11.0  years,  are 94%  natural  gas and are 88%
proved  developed.  After  allocating  $25  million  of the  purchase  price  to
unevaluated   leasehold  for  probable  and  possible   reserves,   Chesapeake's
acquisition  cost per mcfe of proved reserves will be $1.38.  The acquisition is
expected  to  close on  January  31,  2003 and is  subject  to  satisfaction  of
customary closing conditions.

                          ASSET HISTORY AND DESCRIPTION

     ONEOK  and  its  affiliates  have a long  operating  history  in  Oklahoma,
commencing  with the  drilling  of  their  first  gas  supply  wells in  eastern
Oklahoma's  Arkoma  Basin in the early  1900's to provide  retail gas service in
Oklahoma.  Through value-added drilling and strategic acquisitions over a number
of years, ONEOK has developed one of the highest-quality natural gas asset bases
in the Mid-Continent and owns substantial interests in a number of fields in the
Anadarko and Arkoma Basins that are very  significant to Chesapeake,  including:
South Panola,  Red Oak,  Wilburton,  Brooken and Quinton in the Arkoma Basin and
Hugoton, Watonga-Chickasha,  Carpenter, Strong City, Clinton, Arapaho, Morewood,
Thomas,  Eakly,  Verden,  Sahara,  Bradley,  Golden  Trend and  Springer  in the
Anadarko  Basin.  Of the  properties  being  acquired,  87% are  located  within
townships in which Chesapeake already owns properties.  Chesapeake believes that
the consolidation of assets in these fields will result in numerous  operational
efficiencies and enhanced drilling opportunities.

                               MANAGEMENT COMMENTS

     Aubrey K. McClendon,  Chesapeake's Chief Executive Officer,  commented, "We
are very pleased to announce our most recent  acquisition of  Mid-Continent  gas
assets.  The ONEOK  acquisition  fits perfectly with our existing  Mid-Continent
assets and with  Chesapeake's  business  strategy of creating value by acquiring
and  developing  low-cost,  long-lived  natural gas assets in the  Mid-Continent
region of the U.S. This  transaction will increase our company's proved reserves
to almost 2.5 tcfe and our  current  production  to over  565,000  mcfe per day.
Based  on  the  results   achieved  from  our  previous   acquisitions   in  the
Mid-Continent, we expect to substantially increase the value of ONEOK's reserves
through additional  drilling,  lower  administrative costs and reduced operating
costs.

     Since January 1998,  our company has discovered or acquired over three tcfe
of proved natural gas reserves at the very attractive  average cost of less than
$1.20 per mcfe.  As a result,  Chesapeake  has become the  largest  producer  of
natural  gas  in the  Mid-Continent,  one of the  ten  largest  independent  gas
producers in the U.S. and one of the most profitable  companies in the industry.
We believe the combination of our successful  acquisition and drilling programs,
high  revenue   realizations,   low  operating  costs  and  value-added  hedging
strategies will enable Chesapeake to continue generating top-tier returns to our
investors.  In the past three years,  Chesapeake  has  delivered the second best
stock price performance in the industry and one of the top 10 performances among
all NYSE-listed companies. Today's announcement provides further evidence of our
ongoing   commitment  to  creating   industry-leading   value  through   further
consolidation of high-quality gas assets in the Mid-Continent."
