Magnum Hunter Resources Announces Additional Expansion to Senior Bank Credit Facility

HOUSTON, TX--(Marketwire - Aug 15, 2011) - Magnum Hunter Resources Corporation (NYSE: MHR) (NYSE Amex: MHR-PrC) (NYSE Amex: MHR-PrD) (the "Company" or "Magnum Hunter") announced today that it has entered into an amendment under its $250 million senior secured revolving credit facility ("the Bank Facility") to increase the borrowing base (the "Borrowing Base"). The Company's Borrowing Base is increasing via two tranches. Today, the Borrowing Base has been increased from $170 million to $187.5 million. Upon the completion of the recently announced acquisition (Press Release dated August 5, 2011) of certain North Dakota properties (the "North Dakota Acquisition"), the Borrowing Base will increase again to $230 million (the "New Borrowing Base"). Closing of this transaction will be on or before August 18, 2011. The 35% increase in Magnum Hunter's Borrowing Base is a reflection of the addition of proved reserves from the Company's ongoing drilling programs in its core resource regions and the addition of approximately 2.5 mmboe of proved reserves associated with approximately 7,500 net acres located in the Williston Basin of North Dakota.

The amendment to the revolving credit facility agreement will be filed with the Securities and Exchange Commission in due course. The Bank Facility is governed by a semi-annual borrowing base redetermination derived from the Company's total proved crude oil and natural gas reserves.

Today, the Company had $159 million of outstanding indebtedness under its existing bank credit facility which with available cash, provides for approximately $35 million of current liquidity. The Company expects its liquidity position to be further enhanced upon the completion of the North Dakota Acquisition and upon the closing of a new non-recourse loan financing facility for its Eureka Hunter Pipeline (the "Eureka Finance Facility"). The Company has expended approximately $20 million on its Eureka Hunter Pipeline since June 30, 2011, accounting for the majority of the increase in the Company's outstanding indebtedness since that date. The Company expects to receive substantially all of the capital expended since the end of the second quarter as well as funding for the ongoing capital expenditures for Eureka Hunter through the new Eureka Finance Facility. As a result, the Company expects liquidity to exceed $50 million upon completion of these transactions, all of which are anticipated this week.

Bank of Montreal serves as the "Administrative Agent" under the facility, with Capital One, N.A. serving as the "Syndication Agent," and Amegy Bank National Association, KeyBank National Association and UBS Securities LLC serving as "Documentation Agents." BMO Capital Markets serves as "Lead Arranger" and "Sole Bookrunner." Participating banks include Citibank, N.A., Credit Suisse AG, Deutsche Bank Trust Company Americas, Goldman Sachs Bank USA and Union Bank, N.A.

Management Comments

Mr. Gary C. Evans, Chairman of the Board and Chief Executive Officer, commented, "Since the beginning of this year, our Company's availability under our Bank Facility has increased four times from $71.5 million at December 31, 2010 to $230 million this week which reflects a 322% increase in just eight months. This is due to the rapid additions in our proved reserves and associated daily production. We are now in direct control as operator of over 75% of our annual capital budget program. With these new financings along with our ever increasing cash flow, management anticipates ample liquidity to fund our capital needs well into fiscal year 2012."
