                    INFORMATION TO BE INCLUDED IN THE REPORT


ITEM 12. DISCLOSURE OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION

         We issued a press release on July 28, 2003, which includes  information
regarding our consolidated  results of operations and financial  condition as of
and for the  quarterly  period ended June 30,  2003.  It also  includes  updated
information  on our 2003 outlook.  The text of that press release is attached to
this Report as an exhibit and is incorporated by reference herein.

         The press release contains  information  concerning  financial measures
that  we  use  that  may  be  considered  "non-GAAP  financial  measures"  under
Securities  and  Exchange  Commission  rules.  Specifically,  the press  release
contains  information  concerning operating cash flow (defined as cash flow from
operating  activities before changes in assets and liabilities) and EBITDA, each
of which is reconciled in the press release to cash from  operating  activities,
the most directly comparable financial measure reported under generally accepted
accounting principles.

         With the  filing  of this  report on Form 8-K and the  issuance  of the
attached press release,  we are also updating our future  outlook,  which can be
found on our  website at  www.chkenergy.com.  We caution you that our outlook is
given as of July 28, 2003 based on currently available information,  and that we
are not undertaking any obligation to update our estimates as conditions  change
or other information becomes available.

         This information,  including the exhibit attached hereto,  shall not be
deemed  "filed" for  purposes of Section 18 of the  Securities  Exchange  Act of
1934,  as amended (the  "Exchange  Act"),  or  incorporated  by reference in any
filing under the Securities Act of 1933, as amended, or the Exchange Act, except
as may be  expressly  set forth by specific  reference in this Report other than
under Item 12 hereof.
