The new senior secured revolving credit facility replaced the Company’s existing $1.5 billion senior secured revolving credit facility which had been entered into as of May 7, 2010 (the “Old Facility”).

CNX Gas, a wholly owned subsidiary of CONSOL Energy, and its wholly-owned subsidiaries entered into an Amended and Restated Credit Agreement dated as of April 12, 2011 (the “CNX Gas Credit Agreement”) for a $1.0 billion senior secured revolving credit facility with certain lenders, PNC Bank, National Association as administrative agent, Bank of America, N.A. as syndication agent, The Bank of Nova Scotia, The Royal Bank of Scotland PLC and Wells Fargo Bank, N.A. as co-documentation agents and PNC Capital Markets LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated as joint lead arrangers.

The new CNX Gas senior secured revolving credit facility replaced CNX Gas’ existing $700 million revolving credit facility which had been entered into as of May 7, 2010 (the “CNX Gas Old Facility”).

Consol Energy Inc.

The Credit Agreement provides for a secured revolving credit facility (the “Credit Facility”) in an aggregate outstanding principal amount of up to $1.5 billion, including borrowings and letters of credit. In addition to refinancing all outstanding amounts under the Old Facility, borrowings under the Credit Facility may be used by CONSOL Energy for general corporate purposes.

Interest on outstanding indebtedness under the Credit Facility currently accrues, at the Company’s option, at a rate based on either:

the greater of (i) the federal funds open rate plus 0.5%, (ii) PNC Bank, National Association’s prime rate,

and (iii) the daily LIBOR rate plus 1.0%,

in each case, plus a margin ranging from 0.75% to 1.75%

or

the LIBOR rate plus a margin ranging from 1.75% to 2.75%.

The Credit Facility matures on April 12, 2016, and requires compliance with conditions precedent that must be satisfied prior to any borrowing as well as ongoing compliance with certain affirmative and negative covenants to which CONSOL Energy and most of its wholly-owned subsidiaries must adhere.

The affirmative covenants include, among others: (i) preservation of existence; (ii) payment of obligations, including taxes; (iii) maintenance of properties, insurance, leases, books and records, coal supply agreements and material contracts; (iv) compliance with laws; (v) use of proceeds; (vi) subordination of intercompany loans; (vii) anti-terrorism laws; and (viii) collateral.

The negative covenants of the Credit Facility include restrictions on the ability of CONSOL Energy and its subsidiary guarantors (excluding CNX Gas and its subsidiaries ) except in certain circumstances: (i) to create, incur, assume or suffer to exist indebtedness; (ii) to create or permit to exist liens on properties; (iii) to guaranty the debt of another party; (iv) to make loans or investments in excess of certain amounts except for permitted investments; (v) to make or pay dividends or distributions on CONSOL Energy common stock in excess of an annual rate of $0.40 per share unless certain conditions are met; (vi) to merge, liquidate, and dissolve to make acquisitions; (vii) to dispose of assets in excess of certain amounts subject to certain ordinary course and other exceptions; (viii) to deal with any affiliate except on fair and reasonably arm’s length terms; (ix) to create certain subsidiaries and joint ventures; (x) to engage in other businesses; (xi) to change fiscal year; (xii) other than the Company, to issue additional equity to any person other than the Company or the other loan parties; (xiii) to amend certificates of incorporation, bylaws, or other organizational documents; (xiv) to make prepayments on or amendments to the Company’s senior notes; (xv) to permit restrictions on upstream dividends and payments to loan parties; or (xvi) to enter into agreements inconsistent with the Credit Agreement and loan documents. In addition, the Company is obligated to maintain at the end of each fiscal quarter (x) a leverage ratio not greater than 4.75 to 1.0 through March 31, 2013 and from June 30, 2013 and thereafter 4.50 to 1.0, subject to adjustment for certain dispositions; (y) an interest coverage ratio equal to or greater than 2.5 to 1.0; and (z) a senior secured leverage ratio not greater than 2.0 to 1.0; all as calculated in accordance with the terms and definitions determining such ratios contained in Credit Agreement. The Credit Agreement also contains various reporting requirements.

The Credit Facility also contains customary events of default, including, but not limited to, a cross-default to certain other debt, breaches of representations and warranties, change of control events and breaches of covenants.

The obligations under the Credit Agreement are secured by substantially all of the assets of the Company and its subsidiaries (excluding CNX Gas and its subsidiaries and certain other subsidiaries) pursuant to the existing Amended and Restated Collateral Trust Agreement, as amended by the CONSOL Successor Agent Agreement, the Amended and Restated Pledge Agreement, the Amended and Restated Security Agreement, the Amended and Restated Patent, Trademark and Copyright Security Agreement, as well as various mortgages.

CNX Gas Corporation

The CNX Gas Credit Agreement provides for a secured revolving credit facility (the “CNX Gas Credit Facility”) in an aggregate outstanding principal amount of up to $1.0 billion, including borrowings and letters of credit. In addition to refinancing all outstanding amounts under the CNX Gas Old Facility, borrowings under the CNX Gas Credit Facility may be used by CNX Gas for general corporate purposes.

The availability under the CNX Gas Credit Facility, including availability for letters of credit, is generally limited to a borrowing base, which is determined by the required number of lenders in good faith by calculating a loan value of CNX Gas’ proved reserves and reducing that number by an equity cushion determined by the lenders required to approve the borrowing base.

Interest on outstanding indebtedness under the CNX Gas Credit Facility currently accrues, at CNX Gas’ option, at a rate based on either:

the greater of (i) the federal funds open rate plus 0.5%, (ii) PNC Bank, National Association’s prime rate,

and (iii) the daily LIBOR rate plus 1.0%,

in each case, plus a margin ranging from 0.5% to 1.5%

or

the LIBOR rate plus a margin ranging from 1.5% to 2.5%.

The applicable margin added to the underlying interest rate fluctuates based on the facility utilization percentage.

The CNX Gas Credit Facility matures on April 12, 2016, and requires compliance with conditions precedent that must be satisfied prior to any borrowing as well as ongoing compliance with certain affirmative and negative covenants to which CNX Gas and its wholly-owned subsidiaries must adhere.

The affirmative covenants include, among others: (i) preservation of existence; (ii) payment of liabilities, including taxes; (iii) maintenance of properties, insurance, intellectual property and books and records; (iv) compliance with laws, leases, pipeline arrangements and other material contractual obligations; (v) use of proceeds; (vi) subordination of intercompany loans; (vii) anti-terrorism laws; and (viii) collateral and access to title information.

The negative covenants of the CNX Gas Credit Facility include restrictions on the ability of CNX Gas and its subsidiary guarantors except in certain circumstances: (i) to create, incur, assume or suffer to exist indebtedness; (ii) to create or permit to exist liens on properties; (iii) to guaranty the debt of another party; (iv) to make loans or investments in excess of certain amounts except for permitted investments; (v) to make or pay any dividends or distributions to third parties in excess of certain amounts subject to certain conditions; (vi) to merge, liquidate, or dissolve; (vii) to dispose of assets in excess of certain amounts subject to certain ordinary course and other exceptions; (viii) to deal with any affiliate except on fair and reasonably arm’s length terms; (ix) creation of certain subsidiaries and joint ventures; (x) to engage in other businesses; (xi) to change fiscal year; (xii) other than CNX Gas, to issue additional equity to any person other than CNX Gas or its wholly-owned subsidiaries; (xiii) to amend certificates of incorporation, bylaws, or other organizational documents; (xiv) to enter into any hedging agreement other than those permitted by the CNX Gas Credit Agreement in the ordinary course of CNX Gas’ business; (xv) to sell, transfer or convey or voluntarily pool or unitize its proved reserves; (xvi) to permit restrictions on upstream dividends and payments to loan parties; or (xvii) to enter into agreements inconsistent with the CNX Gas Credit Agreement and loan documents. In addition, CNX Gas is obligated to maintain as of the end of each fiscal quarter a leverage ratio of not greater than 3.5 to 1.0 and an interest coverage ratio equal to or greater than 3.0 to 1.0, as calculated in accordance with the terms and definitions determining such ratios contained in CNX Gas Credit Agreement. The CNX Gas Credit Agreement also contains various reporting requirements.

The CNX Gas Credit Facility also contains customary events of default, including, but not limited to, a cross-default to certain other debt, breaches of representations and warranties, change of control events and breaches of covenants.

The obligations under the CNX Gas Credit Agreement are secured by substantially all of the assets of CNX Gas and its subsidiaries pursuant to the existing Amended and Restated Collateral Trust Agreement, as amended by the CNX Gas Successor Agent Agreement, the CNX Gas Pledge Agreement and the CNX Gas Security Agreement, as well as various mortgages.
