                               Management Comment


Aubrey K. McClendon,  Chairman and Chief Executive  Officer of Chesapeake  said,
"We are extremely pleased for Jeff to join Chesapeake's management team. We have
known Jeff for years and have admired his  research  insights,  especially  with
regard to his early  appreciation for the  sustainability of the upward movement
in oil and  natural  gas  prices  during  the past five  years.  I  believe  our
investors  will enjoy  getting to know Jeff  better in his new role in the years
ahead.

We are also pleased that Tom Price will now have more time to concentrate on his
duties in the corporate development arena, including  governmental,  public, and
media  relations,  as well as other areas where the company can  strengthen  its
relationship with its various  stakeholders.  As our company has grown from a $2
billion to an $11 billion enterprise over the past five years, we have needed to
expand  our  government  relations  and  corporate  development  areas.  Today's
announced personnel moves strengthen our company in these important areas."
