 “Each Borrower acknowledges that, pursuant to the Proceeds of Crime (Money Laundering) and Terrorist
Financing Act (Canada) and other applicable Canadian anti-money laundering, anti-terrorist financing, government sanction and “know your client” laws, the Lenders and the Administrative Agent may be required to obtain, verify and
record information regarding such Borrower, its directors, authorized signing officers, direct or indirect shareholders or other Persons in Control of such Borrower, and the transactions contemplated hereby.” 

(o) Schedule 2.02 of the Credit Agreement is hereby deleted in its entirety.

Loans. Each Lender party to the Credit Agreement immediately prior to the Third Amendment Effective Date (used herein as defined below) has, in consultation with the Borrower, agreed to reallocate its respective Maximum Credit Amount and
Commitment and to, among other things, allow CIT Finance LLC to become a party to the Credit Agreement as a Lender, (the “New Lender”) by acquiring an interest in the Aggregate Maximum Credit Amounts and Commitments. The
Administrative Agent and the Borrower hereby consent to such reallocation and the New Lender’s acquisition of an interest in the Maximum Credit Amounts and Commitments. On the Third Amendment Effective Date and after giving effect to such
reallocations, the Maximum Credit Amounts and Commitment of each Lender (including the New Lender) shall be as set forth on Annex I to this Third Amendment, which Annex I supersedes and replaces Annex I to the Credit Agreement, and the New Lender
shall become a party to the Credit Agreement, as amended by this Third Amendment, as a “Lender” and have all of the rights and obligations of a Lender under the Credit Agreement, as amended by this Third Amendment, and the other Loan
Documents. With respect to such reallocation, the New Lender shall be deemed to have acquired the Maximum Credit Amount and Commitment assigned to it from the existing Lenders pursuant to the terms of the Assignment and Assumption attached as
Exhibit F to the Credit Agreement as if the New Lender and such existing Lenders executed an Assignment and Assumption with respect to such allocation pursuant to which the term “Effective Date” shall be the “Third Amendment Effective
Date” as defined herein and item 6 therein shall be deemed to be deleted. Notwithstanding Section 12.04(b)(ii)(C), the Lenders deemed to be parties to the Assignment Agreement shall not be required to pay a processing and recordation fee
of $3,500 to the Administrative Agent. On the Third Amendment Effective Date, the Administrative Agent shall take the actions specified in Section 12.04(b)(v), including recording the assignment described herein in the Register, and such
assignment shall be effective for purposes of the Credit Agreement. If, on the Third Amendment Effective Date, any Eurodollar Loans have been funded, then the Borrower shall be obligated to pay any breakage fees or costs that are payable pursuant to
Section 5.02, in connection with the reallocation of such outstanding Eurodollar Loans to effectuate the provisions of this paragraph. 

  
 3 

 3.2 Borrowing Base Increase. For the period from and including the Third Amendment
Effective Date to but excluding the next Redetermination Date, the amount of the Borrowing Base shall be equal to $87,500,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from time to time pursuant to
Section 2.07(e), Section 8.13(c) or Section 9.12(d). For this avoidance of doubt, this Borrowing Base increase shall constitute the October 1, 2013 Scheduled Redetermination. 

Section 4. Amendments to Parent Guaranty. 

4.1 Amendments to Section 1(b). Section 1(b) of the Parent Guaranty is hereby amended as follows:

time, and any successor statute. 
 “Excluded Swap Obligation” means, with respect to the Guarantor, any
Swap Obligation if, and to the extent that, all or a portion of the guarantee of the Guarantor of, or the grant by the Guarantor of a security interest to secure, such Swap Obligation (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 the Guarantor’s failure for any reason to constitute an
“eligible contract participant” as defined in the Commodity Exchange Act and the regulations thereunder at the time the guarantee of the Guarantor or the grant of such security interest becomes effective with respect to such Swap

becomes illegal.
