                    INFORMATION TO BE INCLUDED IN THE REPORT


ITEM 9.  REGULATION FD DISCLOSURE

     Chesapeake  Energy  Corporation  ("Chesapeake")  issued a Press  Release on
April 9, 2003. The following was included in the Press Release:


            CHESAPEAKE ENERGY CORPORATION ANNOUNCES ITS FIRST QUARTER
                  2003 PRODUCTION WILL EXCEED PREVIOUS GUIDANCE

       FULL-YEAR 2003 GUIDANCE ALSO INCREASED; COMPANY'S DEEP GAS DRILLING
            RESULTS CONTINUE TO EXCEED EXPECTATIONS; EARLY CLOSING OF
              EL PASO TRANSACTION ALSO BOOSTS FIRST QUARTER RESULTS

OKLAHOMA  CITY,  OKLAHOMA,   APRIL  9,  2003  -  Chesapeake  Energy  Corporation
(NYSE:CHK)  today  announced that it has increased its projected  range of first
quarter 2003  production  guidance to 55.0 - 55.5 billion  cubic feet of natural
gas  equivalent  (bcfe),  an increase of 8% from its February 25, 2003 guidance.
For the quarter, daily production is expected to average 611 - 617 million cubic
feet of gas equivalent (mmcfe), 90% of which will be natural gas.

Chesapeake's new first quarter 2003 guidance is an increase of 4.0 bcfe over the
previous range of 51.0 - 51.5 bcfe, or daily  production of 567 - 572 mmcfe.  Of
this increase,  50% is attributable to the El Paso transaction closing one month
earlier than expected and 50% is associated with Chesapeake's  drilling programs
generating better than forecasted production levels.

Chesapeake is also  announcing  today an increase in its second quarter 2003 and
full-year  2003  production  guidance  to 60.0 - 60.5  bcfe and 237 - 243  bcfe,
increases  of 5% and 3% from the  previous  ranges of 57.0 - 57.5 bcfe and 230 -
235  bcfe.  Of  the  projected  full-year  2003  increase  of 7-8  bcfe,  25% is
attributable  to the early El Paso  closing  with 75%  related  to  Chesapeake's
better than  forecasted  drilling  success.  As a result of this recent drilling
success and an increasing number of newly identified high-potential  exploration
prospects  developed by the company's  geoscientists,  Chesapeake has decided to
increase its drilling,  land and seismic capital  expenditure budget to $575-600
million from previous guidance of $525 million.


                               MANAGEMENT COMMENTS

Aubrey K. McClendon,  Chesapeake's Chief Executive Officer,  commented,  "We are
very pleased to announce updated production guidance generated by the success of
our Mid-Continent focused,  deep-gas drilling program.  Chesapeake's  production
growth  trends  are  significant,  sustainable  and  being  driven  by  teams of
geoscientists,  engineers and landmen that are unmatched in their  Mid-Continent
talent and experience.  Although Chesapeake is only the 18th largest producer of
gas in the U.S. (and the 8th largest  independent gas producer),  the company is
conducting  the 3rd most active  drilling  program  and is drilling  the deepest
wells in the country on average.  In fact, 14 of  Chesapeake's  33 operated rigs
are  targeting  formations  deeper than 15,000 feet.  In  addition,  4 of the 10
deepest  wells  currently  being  drilled in the U.S. are operated by Chesapeake
(see attached tables)."

"Chesapeake  is committed to the  exploration of gas targets  between  15-25,000
feet  because  of our  conviction  that it is at these  depths  where  large new
reserves  of  natural  gas are most  likely  to be  found  in the U.S.  Our deep
drilling  programs  have been  successful  because  of the  company's  unrivaled
commitment to leading-edge  geoscience and to building an inventory of leasehold
that is second to none in the  Mid-Continent.  Chesapeake  owns over 2.2 million
net acres of leasehold  and 8,000 square miles of 3-D seismic,  much of which is
proprietary to Chesapeake.  In addition,  the company will continue building the
foundation  for future growth by  committing  $100 million this year to new land
and 3-D seismic acquisition and evaluation."

"Although our acquisition  activity  during the first quarter was  extraordinary
and increased our proven  reserves and  production by more than 20%, the size of
the  acquisitions  and the related  financings have obscured the strength of the
company's  underlying  organic production growth. In an industry where 13 of the
20 largest gas  producers  experienced  U.S.  gas  production  declines in 2002,
Chesapeake's  ability to generate  significant  growth  through the  drillbit is
increasingly distinctive."
