PURPOSE

Section 1.1 Purpose . This 2003 Stock Incentive Plan is established by Chesapeake Energy Corporation (the “Company”) to create incentives which are designed to motivate Employees and Consultants to put forth maximum effort toward the success and growth of the Company and to enable the Company to attract and retain experienced individuals who by their position, ability and diligence are able to make important contributions to the Company’s success. Toward these objectives, the Plan provides for the granting of Options and Restricted Stock Awards to Employees and Consultants on the terms and subject to the conditions set forth in the Plan. The Plan is designed to align the interests of participants with those of shareholders through the use of stock-based incentives.

Section 1.2 Establishment . The Plan is effective as of April 15, 2003 and for a period of 10 years from such date. The Plan will terminate on April 14, 2013; however, it will continue in effect until all matters relating to the exercise of Options, distribution of Awards and administration of the Plan have been settled.

Section 1.3 Shares Subject to the Plan . Subject to the limitations and adjustments set forth in this Plan, Awards may be made under this Plan for a total of 10,000,000 shares of Common Stock.

Section 1.4 Shareholder Approval. The Plan shall be subject to Shareholder Approval, which must occur within the period ending twelve months after the date the Plan is adopted by the Board. Pending such Shareholder Approval, Awards under the Plan may be granted, but Options may not be exercised nor may Restricted Stock Awards vest prior to receipt of such Shareholder Approval. In the event such Shareholder Approval is not obtained within such twelve-month period, all such Awards shall be void.
