A copy of the press release is attached as Exhibit 99.1 hereto and is incorporated herein by reference. Commitment Letter for Potential Debt Financing On March 8, 2013, the Company entered into a commitment letter with Citigroup Global Markets Inc. ("Citigroup"), Bank of America, N.A. ("Bank of America"), and Merrill Lynch, Pierce, Fenner & Smith Incorporated, ("Merrill Lynch"), pursuant to which, and subject to the terms and conditions set forth therein, Citigroup (on behalf of its affiliates) and Bank of America (on behalf of its affiliates) each committed to lend the Company $100 million under a new $300 million senior secured revolving credit facility. An affiliate of Citigroup is expected to act as administrative agent, and Bank of America is expected to be the syndication agent. Citigroup and Merrill Lynch, each in its capacity as bookrunner and lead arranger agreed to use their commercially reasonable efforts to arrange a syndicate of lenders to lend the remaining $100 million. On March 8, 2013, Bank of Montreal committed, in its capacity as a co-lead arranger and documentation agent, to lend, subject to certain conditions, the remaining $100 million under the new credit facility. This new facility is expected to replace the Company's existing $150 million senior secured revolving credit facility and could be increased to up to $600 million, subject to the satisfaction of certain conditions and the approval of the administrative agent. This potential new facility is contemplated to have a four-year term with an option to extend for one additional year and to bear interest at a floating rate based on Eurodollar plus a margin that is determined based on the Company's leverage ratio, which can range from 1.65% to 2.90%. The new facility is expected to be secured by a first priority lien on all of the Company's equity interests in each entity that owns, directly or indirectly, all or a portion of the properties constituting the borrowing base and collateral assignments of the Company's senior and junior debt positions in certain borrowing base properties. The closing of this new credit facility is subject to the negotiation and execution of definitive documentation acceptable to the parties and is subject to closing contingencies. The Company cannot assure that it will be able to successfully establish this new credit facility on the terms described above or at all.
