SECURITY AND ISSUER. This Amendment No. 1 to Schedule 13D relates to the common stock, $.01 par value per share, of Chesapeake Energy Corporation, an Oklahoma corporation, and amends the Schedule 13D filed by Floyd C. Wilson on March 19, 1998. ITEM 4. PURPOSE OF TRANSACTION. Chesapeake Energy Corporation issued an additional 5,000,000 shares of common stock pursuant to the merger between Chesapeake Energy Corporation and DLB Oil & Gas, Inc., which was effective on April 28, 1998. As a result of such issuance, Mr. Wilson will cease to be a reporting person inasmuch as Chesapeake Energy Corporation has 105,105, 598 shares of common stock outstanding and Mr. Wilson no longer owns greater than 5% of the outstanding shares of Chesapeake Energy Corporation. After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
