SECTION 1 - REGISTRANT'S BUSINESS AND OPERATIONS

ITEM 1.01  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT


On October 1, 2004,  Chesapeake  Energy  Corporation  granted each  non-employee
director  options to purchase  12,500  shares of its common stock at an exercise
price of $16.08 per  share,  which was the  closing  price of the shares on such
date.  Directors  who  received  grants are Breene M.  Kerr,  Frank A.  Keating,
Charles T.  Maxwell,  Shannon T. Self and Frederick B.  Whittemore.  The options
will expire three years  following  an  optionee's  termination  of service as a
director or, if earlier,  on the tenth  anniversary of the date of grant.  If an
optionee's  membership  on the  Board of  Directors  is  terminated  for  cause,
however,  the options will expire thirty days after such termination.  The grant
of options to purchase  8,000 shares was made subject to  shareholder  approval.
The remaining options to purchase 4,500 shares are immediately exercisable.

The options  are  generally  nontransferable,  but are  transferable  to (i) the
ex-spouse of an optionee pursuant to the terms of a qualified domestic relations
order, (ii) the spouse, children or grandchildren of the optionee, (iii) a trust
for  the  exclusive  benefit  of  such  immediate  family  members,  or  (iv)  a
partnership in which such immediate family members are the only partners.
