Security and Issuer. This Amendment No. 2 to Schedule 13D amends the original Schedule D filed by ONEOK Texas Resources, Inc. ("ONEOK Texas Resources") dated as of February 3, 1999 and Amendment No. 1 to Schedule 13D filed as of April 16, 2002, and relates to (a) common stock, par value $0.01 per share ("Common Stock"), of Magnum Hunter Resources, Inc. (the "Issuer") held by ONEOK Texas Resources, and (b) common stock purchase warrants ("Warrants") publicly issued by the Issuer in a registered offering on or about March 21, 2002 held by ONEOK Texas Resources. The address of the principal executive office of the Issuer is: 600 E Las Colinas Blvd., Suite 1100, Irving, TX 75039. Item 4. Purpose of Transaction Item 4 is hereby amended to add a fifth paragraph which reads in its entirety as follows: On June 4, 2002, ONEOK sold 4,963,504 shares of Magnum Hunter Common Stock for net proceeds of approximately $35.8 million. The proceeds from the sale will be used to reduce ONEOK's outstanding commercial paper indebtedness. Item 5. Interests in Securities of the Issuer Paragraph (a) of Item 5 is hereby amended to read in its entirety as follows: (a) As a result of the sale described in Item 4 above, the aggregate number of shares beneficially owned by the reporting person, including the persons described in Item 2 of the original Schedule 13D, is 1,576,500 shares of Common Stock, representing in the aggregate approximately 2.2% of the outstanding Common Stock of Magnum Hunter. Of that total amount, ONEOK Texas Resources beneficially owns 1,515,300 shares of Common Stock (approximately 2.1%), David Kyle, an executive officer of ONEOK Texas Resources, beneficially owns 51,000 shares of Common Stock (less than 0.1%), and Jim Kneale, an executive officer of ONEOK Texas Resources, beneficially owns 10,200 shares of Common Stock (less than 0.1%). These beneficial ownership amounts include the right of ONEOK Texas Resources to acquire Common Stock within 60 days through the exercise of warrants acquired in 2002 as described in Item 1 of the original Schedule 13D previously filed, and the right of the individuals named above to acquire Common Stock within 60 days through the exercise of stock options. The following sentence is hereby added to Paragraph (c) of Item 5: On June 4, 2002, ONEOK sold 4,963,504 shares of Magnum Hunter Common Stock for net proceeds of approximately $35.8 million. The proceeds from the sale will be used to reduce ONEOK's outstanding commercial paper indebtedness. In accordance with Rule 13d-2(b), because this amendment reflects beneficial ownership by the reporting person of less than five percent of the class of securities, no additional filings are required with respect to the matters described herein. Signature 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. ONEOK Texas Resources, Inc.
