Planned Appalachian Gathering Joint Venture Between Eureka Hunter Pipeline and DCP Midstream in West Virginia and Ohio

HOUSTON, TX--(Marketwire - September 16, 2010) -  Magnum Hunter Resources Corporation (NYSE Amex: MHR) (NYSE Amex: MHR-PC) (Magnum Hunter, or the Company) announced today that a wholly-owned subsidiary, Eureka Hunter Pipeline, LLC (Eureka Hunter Pipeline), and DCP Midstream Partners, LP (NYSE: DPM) and its sponsor, DCP Midstream, LLC (together, DCP), have entered into a Letter of Intent to create a natural gas gathering joint venture (the Gathering JV) between Eureka Hunter Pipeline and DCP for the gathering of natural gas in West Virginia and Ohio.

Proposed JV Terms

The proposed Gathering JV will construct, own and operate certain natural gas gathering assets for natural gas produced in Western West Virginia and Eastern Ohio. Magnum Hunter and DCP will each own 50 percent of the proposed Gathering JV. The estimated total construction cost to complete the initial gathering pipeline facilities is approximately $35 million, with Magnum Hunter funding approximately $12.5 million of that amount and DCP funding approximately $22.5 million. Terms for the Gathering JV also include a $5 million payment by DCP to Magnum Hunter at closing for certain rights of way that are being contributed by the Company and are in excess of the initial gathering pipeline project.

Once the initial facility is constructed, the two JV partners plan to fund the Gathering JV's future capital requirements for expansion facilities on a 50/50 cost basis. Closing of the proposed joint venture, which is expected to occur during the fourth quarter of 2010, is subject to the negotiation, execution and board approval of definitive documentation and receipt of customary third party consents and approvals.

Operational Update

Magnum Hunter, through its wholly-owned subsidiary, Triad Hunter LLC, owns over 88,000 net mineral acres in Ohio, West Virginia and Kentucky, including approximately 42,000 net acres of prospective Marcellus Shale acreage located in northwestern West Virginia. The Company has identified over 25 horizontal drilling locations across its prospective Marcellus Shale acreage position. Magnum Hunter has recently completed drilling the vertical portions of its first two Marcellus Shale wells (100% Working Interest), the Weese Hunter #1001 and #1002, located in Tyler County, West Virginia. A third party drilling rig has recently begun drilling the lateral sections of both wells.

The gas gathering capacity of the initial facilities constructed by the Gathering JV will be approximately 200 million cubic feet of gas per day. The initial facilities are expected to begin gathering approximately in the 20 to 30 million cubic feet of gas per day range in fourth quarter of this year. This first phase of the system will allow Magnum Hunter to flow natural gas discovered in both the Weese Hunter #1001 and #1002 wells immediately to sales via a tap to Dominion Field Services, and will provide gas gathering services to third party natural gas producers in the vicinity where gas is currently shut-in due to limited pipeline infrastructure.

Management Comments

Gary C. Evans, chairman and CEO of Magnum Hunter Resources Corporation, commented, "Magnum Hunter is very excited to announce this proposed Gathering JV with DCP. After evaluating many proposals from a number of midstream players over the last seven months, we have chosen to partner with DCP due to a combination of reasons. DCP has an industry leading position in natural gas gathering and has extensive midstream operations, broad project development and service capabilities which include both upstream and downstream customer relationships. The proposed Gathering JV is designed to accomplish three key objectives for Magnum Hunter: (i) assure the Company of firm gathering service for its incrementally increasing equity natural gas production volumes as we begin ramping up our Marcellus Shale horizontal drilling program on our significant acreage position over the next several years; (ii) significantly reduce the amount of incremental capital that Magnum Hunter will require going forward for investment in future midstream projects in the region; and (iii) allow the Company to retain a significant equity stake in the gas gathering infrastructure developed in areas of West Virginia and Ohio where limited gas gathering pipeline capacity and facilities exist. The proposed Gathering JV should also create additional opportunities for Magnum Hunter to form new upstream joint ventures that would allow us to further expand our Marcellus Shale ownership interest in the general vicinity of the new pipeline system."

Tom O'Connor, chairman of DCP Midstream Partners, LP, and chairman, president and CEO of DCP Midstream, LLC, stated, "We are excited about the proposed Gathering JV with Magnum Hunter Resources that would expand DCP's natural gas gathering presence in the prolific Marcellus Shale play. It is an excellent opportunity to build on our recently announced entry into the Marcellus through the strategic alliance with EQT Corporation in the Appalachian Basin. This proposed Gathering JV demonstrates our ability to facilitate additional investment opportunities to meet the rapidly growing needs for not only Magnum Hunter, but also other producers. We are very pleased to be working with the management team at Magnum Hunter."
