2.7    Amendment to Article XII of the Credit Agreement. Article XII of the Credit Agreement is hereby amended to insert a new Section 12.22 immediately after Section 12.21 therein to read in full as follows:
Section 12.22    Acknowledgement Regarding Any Supported QFCs. To the extent that the Loan Documents provide support, through a guarantee or otherwise, for Swap Agreements or any other agreement or instrument that is a QFC (such support, “QFC Credit Support” and, each such QFC, a “Supported QFC”), the parties acknowledge and agree as follows with respect to the resolution power of the FDIC under the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with the regulations promulgated thereunder, the “U.S. Special Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support (with the provisions below applicable notwithstanding that the Loan Documents and any Supported QFC may in fact be stated to be governed by the laws of the State of New York and/or of the United States or any other state of the United States):
(a)    In the event a Covered Entity that is party to a Supported QFC (each, a “Covered Party”) becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and obligation in or under such Supported QFC and such QFC Credit Support, and any rights in property securing such Supported QFC or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if the Supported QFC and such QFC Credit Support (and any such interest, obligation and rights in property) were governed by the laws of the United States or a state of the United States. In the event a Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is understood and agreed that rights and remedies of the parties with respect to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support.
(b)    As used in this Section 12.22, the following terms have the following meanings:
BHC Act Affiliate” of a party means an “affiliate” (as such term is defined under, and interpreted in accordance with, 12 U.S.C. 1841(k)) of such party.

(iii)

3.2    Fees and Expenses. The Borrower shall have paid to the Administrative Agent any reasonable out-of-pocket expenses payable to the Administrative Agent and the Lenders pursuant to or in connection with this Second Amendment in accordance with Section 12.03(a) of the Credit Agreement.

Section 4.    Reaffirm Existing Representations and Warranties. The Borrower hereby (a) acknowledges the terms of this Second Amendment and the Credit Agreement; (b) ratifies and affirms its obligations under, and acknowledges its continued liability under, each Loan Document to which it is a party and agrees that each Loan Document to which it is a party remains in full force and effect as expressly amended hereby; and (c) represents and warrants to the Lenders that, as of the date hereof, after giving effect to the terms of this Second Amendment: (i) all of the representations and warranties contained in each Loan Document to which the Borrower is a party are true and correct in all material respects (or, if already qualified by materiality, Material Adverse Effect, or a similar qualification, true and correct in all respects) as of the Second Amendment Effective Date (unless any such representation or warranty relates solely to a specific earlier date, in which case, such representation or warranty was true and correct in all material respects (or, if already qualified by materiality, Material Adverse Effect, or a similar qualification, true and correct in all respects) as of such earlier date); (ii) no Default or Event of Default has occurred and is continuing and the Aggregate Revolving Credit Exposures do not, and will not immediately after giving effect to this Second Amendment, exceed the Borrowing Base; (iii) since the date of the most recent balance sheet delivered pursuant to Section 8.01(a) of the Credit Agreement, no Material Adverse Effect has occurred; (iv) the execution, delivery and performance by the Borrower of this Second Amendment are within Borrower’s corporate powers, have been duly authorized by all necessary corporate action, require no consent or approval of, or filing with, any governmental body, agency or official and do not violate any provision of applicable law or any agreement binding upon Borrower or any other Loan Party, except for violations of agreements that would not reasonably be expected to have a Material Adverse Effect; and (v) this Second Amendment constitutes the valid and binding obligation of the Borrower enforceable in accordance with its terms, except as (A) the enforceability thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditor’s rights generally, and (B) the availability of equitable remedies may be limited by equitable principles of general application, regardless of whether considered in a proceeding in equity or at law.
Section 5.    Miscellaneous.
5.1    Confirmation. The provisions of the Credit Agreement (as amended by this Second Amendment) shall remain in full force and effect in accordance with its terms following the effectiveness of this Second Amendment. This Second Amendment shall constitute a Loan Document.
5.2    No Waiver. Neither the execution by the Administrative Agent or the Lenders party hereto of this Second Amendment, nor any other act or omission by the Administrative Agent or the Lenders or their officers in connection herewith, shall be deemed a waiver by the Administrative Agent or the Lenders of any Defaults or Events of Default which may exist on or after the Second Amendment Effective Date, which may have occurred prior to the Second Amendment Effective Date or which may occur in the future under the Credit Agreement and/or the other Loan Documents. Similarly, nothing contained in this Second Amendment shall directly or indirectly in any way whatsoever either: (a) impair, prejudice or otherwise adversely affect the Administrative Agent’s or the Lenders’ right at any time to exercise any right, privilege or remedy in connection with the Loan Documents with respect to any Default or Event of Default, (b) except as provided herein,

Second Amendment to

amend or alter any provision of the Credit Agreement, the other Loan Documents, or any other contract or instrument, or (c) constitute any course of dealing or other basis for altering any obligation of the Borrower or any right, privilege or remedy of the Administrative Agent or the Lenders under the Credit Agreement, the other Loan Documents, or any other contract or instrument. Nothing in this Second Amendment shall be construed to be a consent by the Administrative Agent or the Lenders to any Default or Event of Default. Each reference in the Credit Agreement to “this Agreement”, “hereunder”, “hereof”, “herein” or any other word or words of similar import shall mean and be a reference to the Credit Agreement as amended hereby, and each reference in any other Loan Document to the Credit Agreement or any word or words of similar import shall be and mean a reference to the Credit Agreement as amended hereby.
5.3    Counterparts. This Second Amendment may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed signature page to this Second Amendment by facsimile transmission or other electronic transmission (including .pdf) shall be as effective as delivery of a manually executed counterpart of this Second Amendment.
5.4    Expenses. As provided in Section 12.03 of the Credit Agreement and subject to the limitations included therein, the Borrower hereby agrees to pay on demand all reasonable out-of-pocket expenses incurred by the Administrative Agent in connection with the negotiation, preparation, and execution of this Second Amendment and all related documents, including, without limitation, the reasonable fees, charges, and disbursements of outside counsel.
5.5    Successors and Assigns. This Second Amendment shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns.
5.6    Severability. Any provision of this Second Amendment held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof or thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.
5.7    No Oral Agreement. This Second Amendment, the Credit Agreement and the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties hereto relating to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof and thereof. This Second Amendment, the Credit Agreement and the other Loan Documents represent the final agreement among the parties hereto and thereto and may not be contradicted by evidence of prior, contemporaneous or subsequent oral agreements of the parties. There are no unwritten oral agreements between the parties.
5.8    Governing Law. THIS SECOND AMENDMENT (INCLUDING, BUT NOT LIMITED TO, THE VALIDITY AND ENFORCEABILITY HEREOF) SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.
