Purpose

Section 1.01 Purpose . This Stock Option Plan (the “Plan”) is established by Continental Resources, Inc. (the “Company”) to create incentives which are designed to motivate its directors, officers and employees to exert 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 to Participants on the terms and subject to the conditions set forth in the Plan.

Section 1.02 Establishment. The Plan is effective as of October 1, 2000 and will terminate on September 30, 2010; provided, however, that the plan shall continue in effect until all matters relating to exercise of options and the administration of the Plan have been settled.

Section 1.03 Shares Subject to the Plan . Subject to Articles IV, VII and IX of this Plan, shares of stock covered by options shall consist of 1,020,000 shares of the Company’s common stock, par value $.01 per share (“Common Stock”).

Section 1.04 Shareholder Approval. The Plan shall be approved by the holders of a majority of the outstanding shares of Common Stock, present, or represented, and entitled to vote at a meeting called for such purposes, which approval must occur within the period ending twelve months after the date the Plan is adopted by the Board. Pending such approval by the shareholders, options may be granted to Participants, but no options may be exercised or paid prior to receipt of shareholder approval. In the event shareholder approval is not obtained within such twelve-month period, all options shall be void.
