ITEM 5.  Other Events

         On  February  3, 2003,  Chesapeake  Energy  Corporation  ("Chesapeake")
issued a press release announcing  completion of the acquisition of $300 million
of Mid-Continent Gas Reserves from ONEOK, Inc. The following was included in the
press release:

OKLAHOMA  CITY,  OKLAHOMA,  FEBRUARY  3, 2003 -  Chesapeake  Energy  Corporation
(NYSE:CHK)  today  announced  that it has  completed  its  previously  announced
acquisition  of  Mid-Continent  gas assets  from a  wholly-owned  subsidiary  of
Tulsa-based ONEOK, Inc. (NYSE:OKE) for $300 million.

The acquisition was funded with proceeds generated from the company's successful
December 2002  offerings of 23 million common shares at $7.50 per share and $150
million of 7.75% senior notes.

This document contains 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  include  estimates  and give our  current
expectations  or forecasts of future  events.  They are based on our  historical
operating  trends,  our  existing  commodity  hedging  position  and our current
estimate of proved reserves.  Although we believe our forward-looking statements
are  reasonable,  they can be affected by inaccurate  assumptions or by known or
unknown risks and  uncertainties.  For example,  statements  concerning the fair
values of 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.  Factors that could
cause actual operating and financial  results to differ materially from expected
results  include  the  volatility  of  oil  and  gas  prices,   our  substantial
indebtedness,  our  commodity  price risk  management  activities,  the cost and
availability  of  drilling  and  production  services,  our  ability  to replace
reserves, the availability of capital,  uncertainties inherent in evaluating our
own reserves and the reserves we acquire, drilling and operating risks and other
risk factors  described  in the  company's  2001 annual  report on Form 10-K and
subsequent filings with the Securities and Exchange Commission.

Chesapeake Energy Corporation is one of the 10 largest  independent  natural gas
producers in the U.S.  Headquartered in Oklahoma City, the company's  operations
are  focused  on 3-D  seismic  delineated  exploratory  drilling  combined  with
developmental  drilling and producing property acquisitions in the Mid-Continent
region   of   the   United   States.   The   company's   Internet   address   is


     Chesapeake also released the following additional  statements in connection
with the announcements described in Item 5:

Based on internal reservoir engineering  estimates,  Chesapeake believes that it
has acquired  approximately  200 billion cubic feet of gas equivalent  (bcfe) of
proved gas  reserves  and  approximately  60 bcfe of probable  and  possible gas
reserves.  The  acquired  properties  are expected to  contribute  approximately
47,000  thousand  cubic feet of gas  equivalent  (mcfe) per day to  Chesapeake's
continued production growth.

Aubrey K. McClendon,  Chesapeake's Chief Executive Officer,  commented,  "We are
pleased  to  announce  the  completion  of  another  successful  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 increases our company's proved
reserves to 2.4 trillion cubic feet of gas equivalent 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. 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."
