Chesapeake Energy Corporation Announces Extension of Senior Notes Exchange Offer

Chesapeake Energy Corporation announced today that it has extended its previously announced exchange offer (the "Offer") for its 8.125% Senior Notes due April 1, 2011 (the "Notes") (CUSIP No. 165167AS6). Chesapeake said that it has extended the deadline for holders to receive the early participation payment, the withdrawal deadline and the expiration date for the offer.

As amended, the deadline for holders to receive an early participation payment in cash of $10.00 for each $1,000 principal amount of Notes validly tendered and accepted for exchange, and the deadline for holders to withdraw tenders, is 5:00 p.m., Eastern Standard Time, on Friday, January 9, 2004.

The new expiration date for the Offer is 5:00 p.m., Eastern Standard Time, on Monday, January 12, 2004. Settlement for Notes validly tendered and accepted is expected to be made on Wednesday, January 14, 2004.

The Offer has been amended to provide that it will only be consummated after, and subject to, the prior completion of an offering of Chesapeake common stock with gross proceeds to the company of at least $225 million.

All other terms and conditions of the Offer remain in effect as previously announced. Holders who have previously tendered Notes in the Offer need not retender their Notes or take any other action in response to this announcement.

On December 22, 2003, Chesapeake announced that it has entered into agreements to acquire $510 million of Mid-Continent, Permian Basin and onshore Gulf Coast oil and natural gas assets. The company announced that it anticipates financing these acquisitions using approximately 50% common equity and 50% debt. Although these acquisitions are expected to be fully closed by January 30, 2004, the closing of these acquisitions is not a condition to consummation of the Offer.
