breakage compensation as required by this Agreement; 

  
 -4- 








 (E) no Lender’s Elected Commitment may be increased without the consent of such Lender
in its sole discretion; 
 (F) if the Borrower elects to increase the Aggregate Elected Commitment Amounts by increasing the Elected
Commitment of a Lender and the Lender so consents in its sole discretion, the Borrower and such Lender shall execute and deliver to the Administrative Agent a certificate substantially in the form of Exhibit M (an “Elected Commitment

Lender Certificate”), together with an Administrative Questionnaire and a processing and recordation fee of $3,500 (provided that the Administrative Agent may, in its discretion, elect to waive such processing and recordation fee in
connection with any such increase), and the Borrower shall (1) if requested by the Additional Lender, deliver a Note payable to such Additional Lender in accordance with this Agreement and (2) pay any applicable fees as may have been

specified in the Elected Commitment Increase Certificate or the Additional Lender Certificate (or if any Eurodollar Advances are outstanding, then the last day of the Interest Period in respect of such Eurodollar Advances, unless the Borrower has
paid any breakage compensation required by this Agreement): (A) the amount of the Aggregate Elected Commitment Amounts shall be increased as set forth therein, and (B) in the case of an Additional Lender Certificate, any Additional Lender party
thereto shall be a party to this Agreement and have the rights and obligations of a Lender under this Agreement and the other Credit Documents. In addition, the Lender or the Additional Lender, as applicable, shall purchase a pro rata portion of the
outstanding Advances (and participation interests in Letters of Credit) of each of the other Lenders (and such Lenders hereby agree to sell and to take all such further action to effectuate such sale) such that each Lender (including any Additional
Lender, if applicable) shall hold its Pro Rata Share of the outstanding Advances (and participation interests) after giving effect to the increase in the Aggregate Elected Commitment Amounts (and the resulting modifications of each Lender’s
Commitment pursuant to Section 2.1(d)(iv) or Section 2.1(d)(v)).

Section 2.1(d)(ii), the Administrative Questionnaire referred to in Section 2.1(d)(ii) and the breakage payments from the Borrower, if any, required by this Agreement, if applicable, the
Administrative Agent shall accept such Elected Commitment Increase Certificate or Additional Lender Certificate and promptly record the information contained therein in the Register required to be maintained by the Administrative Agent pursuant to
Section 10.7(c). No increase in the Aggregate Elected Commitment Amounts shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this
Section 2.1(d)(iv). 
 (v) Upon any increase in the Aggregate Elected Commitment Amounts pursuant to this
Section 2.1(d), (A) each Lender’s Commitment shall be automatically deemed amended to the extent necessary so that each such Lender’s Pro Rata Share of the aggregate Commitments equals the percentage of the
Aggregate Elected Commitment Amounts represented by such Lender’s Elected Commitment, in each case after giving effect to such increase, and (B) Schedule I to this Agreement shall be deemed amended to reflect the Elected Commitment
of each Lender (including any Additional Lender) as thereby increased, any changes in the Lenders’ aggregate Commitments pursuant to the foregoing clause (A), and any resulting changes in the Lenders’ Pro Rata Share of the aggregate
Commitments. 
 (e) Other Changes to Aggregate Elected Commitment Amounts. 

(i) Upon any redetermination or other adjustment in the Borrowing Base pursuant to this Agreement that would otherwise result in the
Borrowing Base becoming less than the Aggregate Elected Commitment Amounts, the Aggregate Elected Commitment Amounts shall be automatically reduced (ratably among the Lenders in accordance with each Lender’s Pro Rata Share of the aggregate
Commitments) so that they equal such redetermined Borrowing Base (and Schedule I shall be deemed amended to reflect such amendments to each Lender’s Elected Commitment and the Aggregate Elected Commitment Amounts). 

(ii) Contemporaneously with any increase in the Borrowing Base pursuant to this Agreement and subject to
Section 2.1(d)(i), if (A) the Borrower elects to increase the Aggregate Elected Commitment Amount and (B) each Lender has consented to such increase in its Elected Commitment then the Aggregate Elected Commitment
Amount shall be increased (ratably among the Lenders in accordance with each Lender’s Pro Rata Share of the aggregate Commitments) by the amount requested by the Borrower (subject to the limitations set forth in
Section 2.1(d)(ii)(A)) without the requirement that any Lender deliver an Elected Commitment Increase Certificate or that the Borrower pay any breakage amounts under this Agreement, and Schedule I shall be deemed
amended to reflect such amendments to each Lender’s Elected Commitment and the Aggregate Elected Commitment Amount. The Administrative Agent shall record the information regarding such increases in the Register required to be maintained by the
Administrative Agent pursuant to Section 10.7(c).

extension; provided that, in any event, such automatic extension may not result in an expiration date that occurs after the fifth Business Day prior to the Maturity Date; 

(g) Section 2.5(d) (Prepayments: Reduction of Commitments) of the Credit Agreement is hereby amended and restated in its entirety
