Item 3. Source and Amount of Funds or Other Consideration

        In connection with entering into the Agreement and Plan of Merger, dated as of January 25, 2005 (the "Merger Agreement"), among Cimarex, Cimarex Nevada Acquisition Co. ("Merger Sub") and Magnum Hunter, Cimarex entered into a Stockholder Voting Agreement, dated as of January 25, 2005 (the "Voting Agreement"), with Gary C. Evans and Jacquelyn Evelyn Enterprises, Inc. (the "Magnum Hunter Stockholders"). Under the Voting Agreement, each Magnum Hunter Stockholder has agreed, among other things, to vote the shares of Magnum Hunter Common Stock held by such Magnum Hunter Stockholder in favor of the Merger Agreement. As a result, Cimarex may be deemed to be the beneficial owner of 4,733,945 shares of Magnum Hunter Common Stock held by the Magnum Hunter Stockholders, including 1,558,151 shares subject to currently exercisable options and warrants. See the response to Item 5.

        Cimarex hereby disclaims beneficial ownership of the 4,733,945 shares of Magnum Hunter Common Stock which are the subject of the Voting Agreement described herein, and the filing of this Amendment No. 1 to Schedule 13D shall not be construed as an admission that Cimarex is, for purposes of Section 13(d) of the Act, the beneficial owner of any such shares of Magnum Hunter Common Stock. Cimarex disclaims membership in any group with respect to the Voting Agreement.

        The descriptions of the Merger Agreement and the Voting Agreement contained herein are qualified in their entirety by reference to such agreements, which are attached hereto as Exhibits 1 and 2, respectively.

Item 4. Purpose of Transaction

        The Voting Agreement was entered into to help facilitate the approval of Magnum Hunter's stockholders required in connection with the merger of Merger Sub with and into Magnum Hunter (the "Merger"). In the Merger, Magnum Hunter will continue as the surviving corporation and will become a wholly owned subsidiary of Cimarex.

        In addition to providing for the Merger, the Merger Agreement restricts Magnum Hunter from, among other things, engaging in certain transactions, including extraordinary corporate transactions (other than the Merger), selling certain assets, changing its capitalization (including by purchasing any of its capital stock or by issuing any capital stock or other voting securities), amending its articles of incorporation or by-laws, paying dividends, incurring indebtedness, making loans or advances to other persons, making certain acquisitions and making certain capital expenditures, and otherwise requires Magnum Hunter to operate in the ordinary course of business. The restrictions described in this paragraph are subject to certain exceptions.

        Under the Merger Agreement, the directors and officers of Merger Sub immediately before the effective time of the Merger will be the directors and officers of the surviving corporation following the Merger.

        In connection with the Merger, it is expected that Magnum Hunter Common Stock will be delisted from the New York Stock Exchange and will become eligible for termination of registration under the Securities Exchange Act of 1934, as amended.

        Except as set forth above, Cimarex has no present plans or proposals that relate to or would result in any of the actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D. Cimarex disclaims membership in any group with respect to the Voting Agreement.

        The descriptions of the Merger Agreement and the Voting Agreement contained herein are qualified in their entirety by reference to such agreements, which are attached hereto as Exhibits 1 and 2, respectively.

Item 5. Interest in Securities of the Issuer

        (a) and (b)    As a result of the Voting Agreement, Cimarex may be deemed to be the beneficial owner of 4,733,945 shares of Magnum Hunter Common Stock held by the Magnum Hunter Stockholders, which would represent approximately 5.2% of Magnum Hunter Common Stock (based on the number of shares outstanding as of January 24, 2005, as set forth in the Merger Agreement). Cimarex disclaims beneficial ownership of the 4,733,945 shares of Magnum Hunter Common Stock and options and warrants therefor which are subject to the Voting Agreement.

        Under the terms of the Voting Agreement, each Magnum Hunter Stockholder has agreed, among other things, to vote (i) in favor of the Merger, the execution and delivery by Magnum Hunter of the Merger Agreement and the approval of the other transactions contemplated by the Merger Agreement and the Voting Agreement, and any actions required in furtherance thereof; (ii) against any proposal relating to a Superior Proposal (as defined in the Merger Agreement); and (iii) against any action or agreement that would (A) impede, frustrate, prevent or nullify the Voting Agreement, (B) result in a breach in any respect of any covenant, representation or warranty or any other obligation or agreement of Magnum Hunter under the Merger Agreement, or (C) result in any of the conditions to Cimarex and Merger Sub's obligations to complete the Merger not being fulfilled. Accordingly, pursuant to the Voting Agreement, Cimarex may be deemed to have acquired shared voting power with respect to the Magnum Hunter Common Stock subject to the Voting Agreement.

        The descriptions of the Merger Agreement and the Voting Agreement contained herein are qualified in their entirety by reference to such agreements, which are attached hereto as Exhibits 1 and 2, respectively.

        (c)    To the best of Cimarex's knowledge, no shares of Magnum Hunter Common Stock are beneficially owned by any of the persons named in Attachment A. Neither Cimarex nor, to the best knowledge of Cimarex, any person named in Attachment A, has effected any transaction in the Magnum Hunter Common Stock during the past 60 days.

        (d)    Other than with respect to the rights granted under the Voting Agreement, Cimarex possesses no powers, rights or privileges with respect to the 4,733,945 shares of Magnum Hunter Common Stock or options or warrants therefor that are owned of record by the Magnum Hunter Stockholders. All other powers, rights and privileges with respect to such shares remain with the Magnum Hunter Stockholders, including the right to vote on all matters unrelated to the Merger Agreement and the right to receive and the power to direct the receipt of dividends from, and the proceeds from the sale of, such securities.

        (e)    Not applicable.
