    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.

  

  

  SECTION 5.  Representations and Warranties.  The
    Borrower represents and warrants to the Administrative Agent and to each of the Lenders that:

   

  (a)  This Amendment and the transactions contemplated thereby are within each Loan Party’s corporate powers and have been
    duly authorized by all necessary corporate and, if required, stockholder action.

   

  (b)  This Amendment has been duly executed and delivered by each Loan Party and constitutes a legal, valid and binding
    obligation of such Loan Party, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity,
    regardless of whether considered in a proceeding in equity or at law.

    in which case such representation and warranty is true and correct in all material respects (or in all respects, as applicable) as of such earlier date; provided
    that, for purposes of the representation in Section 3.17 of the Credit Agreement, the reference to “the Closing Date” therein shall be deemed to refer to “the Amendment Effective Date” and the reference to “the Transactions” shall be deemed to refer to
    the transactions contemplated by this Amendment;

   

  (e)  At the time of and immediately after giving effect to this Amendment, no Default or Event of Default shall have
    occurred and be continuing;

   

  (f)  the Administrative Agent shall have received (i) with respect to each Loan Party, secretary’s certificates of the

    requested in writing to the Borrower not later than ten Business Days prior to the proposed Amendment Effective Date; and

   

  (k)  the Administrative Agent shall have received payment of all fees and expenses required to be paid or reimbursed by
    the Borrower under or in connection with this Amendment, including those expenses set forth in Section 11 hereof, to the extent such fees and expenses are invoiced at least one Business Day prior to the proposed Amendment Effective Date.

    conditions, obligations, covenants or agreements contained in the Credit Agreement or any other Loan Document in similar or different circumstances.  After the Amendment Effective Date, any reference in the Loan Documents to the Credit Agreement shall
    mean the Credit Agreement as modified hereby.  This Amendment shall constitute a “Loan Document” for all purposes of the Credit Agreement and the other Loan Documents.

  SECTION 9.  Applicable Law; Waiver of Jury Trial.
