Recitals

A. The Borrower, the Administrative Agent and the Lenders are parties to that
certain Amended and Restated Credit Agreement dated as of March 5, 2012 (as

2.1 Additional Definitions. Section 1.02 of the Credit Agreement is hereby
amended to add thereto in alphabetical order the following definitions which
shall read in full as follows:

“Commodity Exchange Act” means the Commodity Exchange Act (7 U.S.C. § 1 et
seq.), as amended from time to time, and any successor statute and any
regulations promulgated thereunder.

“Excluded Swap Obligation” means, with respect to any Loan Party individually
determined on a Loan Party by Loan Party basis, any Indebtedness in respect of
any Swap Agreement if, and solely to the extent that, all or a portion of the
guarantee of such Loan Party of, or the grant by such Loan Party of a security
interest to secure, such Indebtedness in respect of any Swap Agreement (or any
guarantee thereof) is or becomes illegal under the Commodity Exchange Act or any
rule, regulation or order of the Commodity Futures Trading Commission (or the
application or official interpretation of any thereof) by virtue of such Loan
Party’s failure for any reason to constitute an “eligible contract participant”
as defined in the Commodity Exchange Act at the time such guarantee or grant of
a security interest becomes effective with respect to such related Indebtedness
in respect of any Swap Agreement. If, with respect to any Loan Party, any
obligation to pay or perform under any agreement, contract or transaction that
constitutes a “swap” within the meaning of Section 1a(47) of the Commodity
Exchange Act arises under a master agreement governing more than one swap, such
exclusion shall apply only to the portion of such obligation that is
attributable to swaps for which such guarantee or security interest is or
becomes excluded in accordance with the first sentence of this definition.

“Fifth Amendment” means that certain Fifth Amendment to Amended and Restated

“Qualified ECP Guarantor” means, in respect of any Swap Agreement, each Loan
Party that (a) has total assets exceeding $10,000,000 at the time any guaranty
of obligations under such Swap Agreement becomes effective or (b) otherwise
constitutes an “eligible contract participant” under the Commodity Exchange Act
and can cause another Person to qualify as an “eligible contract participant” at
such time by entering into a keepwell under Section 1a(18)(A)(v)(II) of the
Commodity Exchange Act.

2.2 Amended Definitions. The definitions of “Applicable Margin”, “Borrowing
Base”, “Commitment”, “Indebtedness”, “Loan Documents”, and “Swap Agreement”
contained in Section 1.02 of the Credit Agreement are hereby amended and
restated in their entirety to read in full as follows:

“Applicable Margin” means, for any day, with respect to any Loan, the applicable

shall be $430,000,000.

“Commitment” means, with respect to each Lender, the commitment of such Lender
to make Loans and to acquire participations in Letters of Credit hereunder,
expressed as an amount representing the maximum aggregate amount of such
Lender’s Credit Exposure hereunder, as such commitment may be (a) modified from
time to time pursuant to Section 2.06 and (b) modified from time to time
pursuant to assignments by or to such Lender pursuant to Section 12.04(b); and
“Commitments” means the aggregate amount of the Commitments of all the Lenders.
The amount representing each Lender’s Commitment shall at any time be the lesser
of (i) such Lender’s Maximum Credit Amount and (ii) such Lender’s Applicable
Percentage of the then effective Borrowing Base. As of the Fifth Amendment
Effective Date, the aggregate Commitments of the Lenders are $430,000,000.

“Indebtedness” means any and all amounts owing or to be owing by the Borrower or
any other Loan Party: (a) to the Administrative Agent, any Issuing Bank, or any

one or more rates, currencies, commodities, equity or debt instruments or
securities, or economic, financial or pricing indices or measures of economic,
financial or pricing risk or value or any similar transaction or any combination

as it relates to such other Loan Parties, voidable under applicable law relating
to fraudulent conveyance or fraudulent transfer, and not for any greater
amount). The obligations of the Borrower under this Section 8.22 shall remain in
full force and effect until all Indebtedness is paid in full to the Lenders and
the Administrative Agent, and all of the Lenders’ Commitments are terminated.

to make any break-funding payments required under Section 5.02 of the Credit
Agreement resulting from the Loans and adjustments described in this

Date, to be $430,000,000 and shall remain at $430,000,000 until the next
Scheduled Redetermination, Interim Redetermination or other adjustment of the
Borrowing Base pursuant to the terms of the Credit Agreement. The Borrowing Base
redetermination provided for herein shall be the May 1, 2013 Scheduled
Redetermination and shall not be considered or deemed to be an Interim
Redetermination of the Borrowing Base for purposes of Section 2.07(b) of the
Credit Agreement. The Borrowing Base increase provided for herein shall be
comprised of the following changes and reaffirmations to the various components

and payable on or prior to the Fifth Amendment Effective Date including, without
limitation, the amendment fee and Borrowing Base increase fee described in
Section 4.3 below.

4.3 The Administrative Agent shall have received (a) an amendment fee for the
benefit of the Lenders (other than the New Lender) in an amount for each such
Lender equal to seven and a half basis points (0.075%) of the lesser of (i) the
amount of such Lender’s Commitment, if any, that was in effect on the Fourth
Amendment Effective Date and (ii) the amount of such Lender’s Commitment after
giving effect to Section 3 hereof and (b) a Borrowing Base increase fee for the
benefit of each Increasing Lender (as defined below), in an amount for each such
Increasing Lender equal to thirty basis points (0.30%) of the amount of such
Increasing Lender’s Increased Commitment (as defined below). As used herein,
“Increasing Lender” means each Lender (including the New Lender) whose
Commitment after giving effect to Section 3 hereof exceeds such Lender’s
Commitment, if any, that was in effect on the Fourth Amendment Effective Date,
and “Increased Commitment” means the amount of such excess.

4.4 The Administrative Agent shall have received duly executed Notes payable to
each Lender requesting a Note in a principal amount equal to its Maximum Credit
Amount (as amended hereby) dated as of the date hereof.

4.5 The conditions set forth in Section 6.02 of the Credit Agreement shall be
satisfied.

Section 5. Amendment to Guaranty Agreement. Effective as of the Fifth Amendment
Effective Date, a new Section 4.16 is hereby added to the Guaranty Agreement
immediately following Section 4.15 thereof, which Section 4.16 shall read in
full as follows:

4.16 Qualified ECP Guarantors. Each Guarantor that is a Qualified ECP Guarantor
hereby guarantees the payment and performance of all Indebtedness of each Loan
Party and absolutely, unconditionally and irrevocably undertakes to provide such
funds or other support as may be needed from time to time to each Loan Party in
order for such Loan Party to honor its obligations under this Guaranty including
obligations with respect to Swap Agreements (provided, however, that each such
Guarantor shall only be liable under this Section 4.16 for the maximum amount of
such liability that can be hereby incurred without rendering its obligations
under this Section 4.16, or otherwise under this Guaranty or any Loan Document,
as it relates to such other Loan Parties, voidable under applicable law relating
to fraudulent conveyance or fraudulent transfer, and not for any greater
amount). The obligations of each such Guarantor under this Section 4.16 shall
remain in full force and effect until all Indebtedness is paid in full to the
Lenders, the Administrative Agent and all other Secured Creditors, and all of
the Lenders’ Commitments are terminated. The parties intend that this
Section 4.16 constitute, and this Section 4.16 shall be deemed to constitute, a
“keepwell, support, or other agreement” for the benefit of each other Loan Party
for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.

analysis and decision independently and without reliance on the Administrative
