SECTION 2 - FINANCIAL INFORMATION

ITEM 2.02 - RESULTS OF OPERATIONS AND FINANCIAL CONDITION

     We issued a press release on February 22, 2005, which includes  information
regarding our consolidated  results of operations and financial  condition as of
and for the quarterly period ended December 31, 2004 and for the full-year 2004.
It also includes updated  information on our 2005 and 2006 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 February 22, 2005 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 2.02 hereof.
