CONTINENTAL RESOURCES ANNOUNCES PARTIAL EXERCISE OF OVERALLOTMENT OPTION

ENID, OKLAHOMA – March 25, 2011/PR Newswire – FirstCall/Continental Resources, Inc. (NYSE:CLR) Continental Resources, Inc. announced today it has completed the sale of 910,000 shares of its common stock. The sale was made in connection with the underwriters’ partial exercise of the overallotment option granted by the Company in connection with the previously announced public offering by it and certain selling shareholders of 10,000,000 shares of the Company’s common stock.

On March 3, 2011, Continental announced it had received net proceeds of approximately $600.2 million, after deducting the underwriting discount, from the issuance and sale of 9,170,000 shares of the Company’s common stock to the public at a price of $68.00 per share ($65.45 per share, net of underwriting discount). Continental received additional net proceeds of approximately $59.5 million, after deducting the underwriting discount, from the partial exercise of the overallotment option.

Continental has used a portion of the total net proceeds from the offering to repay all amounts outstanding under its revolving credit facility and expects to use the remaining net proceeds to accelerate the Company’s multi-year drilling program by funding its increased 2011 capital budget.

The offering was made under Continental’s effective shelf registration statement previously filed with the Securities and Exchange Commission.
