              CHESAPEAKE ENERGY CORPORATION DEFERS TENDER OFFER FOR
                OUTSTANDING SHARES OF CANAAN ENERGY CORPORATION
                   PENDING DISCUSSIONS WITH CANAAN MANAGEMENT

OKLAHOMA CITY, OKLAHOMA - March 15, 2002 - Chesapeake Energy Corporation
(NYSE:CHK) today announced that it has deferred the commencement of the $12.00
per share cash tender offer for all of the outstanding shares of Canaan Energy
Corporation (Nasdaq: KNAN) common stock. Chesapeake had announced on March 11,
2002 its intention to commence the tender offer within the next few days.
Chesapeake's action was based upon the representations of senior management of
Canaan of their willingness to engage in good faith discussions with Chesapeake
management regarding the offer in the near future together with the request by
Canaan management that Chesapeake delay commencement of the tender offer until
after the discussions.

Aubrey K. McClendon, President and Chief Executive Officer of Chesapeake stated,
"We remain committed to take our fair and full offer to the shareholders of
Canaan and are pleased that Canaan's management and advisors have agreed to meet
with us on this issue." McClendon cautioned, however, that Chesapeake may at any
time commence or modify its proposed tender offer for Canaan shares, or
terminate its tender offer plans.

On March 11, 2002, Chesapeake delivered to the board of directors of Canaan its
$12.00 per share cash offer, which represents an aggregate purchase price for
the common stock on a fully diluted basis of approximately $55 million plus the
assumption of Canaan's debt, which was approximately $42 million as of December
31, 2001. The price offered by Chesapeake represents a 31% premium over the
closing price of $9.15 on March 11, 2002, the last day prior to the announcement
of Chesapeake's intent to commence a tender offer, and a 58% premium over
Canaan's closing stock price of $7.60 on November 26, 2001, the last trading day
before Canaan's public announcement of Chesapeake's interest in acquiring
Canaan.
