Chesapeake Energy Corporation today made an announcement regarding its pending exchange offer for up to $500 million aggregate principal amount of its 8.125% Senior Notes due 2011 (CUSIP # 165167AS6). Chesapeake said that, in light of its recent announcement regarding its pending acquisitions of $510 million of oil and gas properties, it will not consummate the exchange offer without extending the expiration date of the offer, as well as withdrawal rights, in order to give holders an opportunity to review the information related to the acquisitions.

Earlier today, 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 acquisitions are expected to be fully closed by January 31, 2004, subject to satisfaction of customary closing conditions. The company announced that it anticipates financing these acquisitions using approximately 50% common equity and 50% short-term and/or long-term borrowings.

The exchange offer is scheduled to expire on December 29, 2003. Approximately $380 million in aggregate principal amount of the 2011 Notes have been tendered to date. A final determination regarding the exchange offer will be made and announced within the next few days.
