Assignors to the extent being assigned under this Agreement and (ii) to the extent permitted to be assigned under applicable law, all claims, suits, causes of action and any other right of the respective Assignors (in their respective
capacities as Lenders) against any Person, whether known or unknown, arising under or in connection with the Credit Agreement, any other documents or instruments delivered pursuant thereto or the loan transactions governed thereby or in any way
based on or related to any of the foregoing, including, but not limited to, contract claims, tort claims, malpractice claims, statutory claims and all other claims at law or in equity related to the rights and obligations sold and assigned pursuant

connection with the Credit Agreement or any other Loan Document, (ii) the execution, legality, validity, enforceability, genuineness, sufficiency or value of the Loan Documents or any collateral thereunder, (iii) the financial condition of
the Borrower, any of its Subsidiaries or Affiliates or any other Person obligated in respect of any Loan Document or (iv) the performance or observance by the Borrower, any of its Subsidiaries or Affiliates or any other Person of any of their
respective obligations under any Loan Document. 
 Each Lender whose Revolving Credit Commitment is increased (or created) by giving effect
to this Amendment, whether by assignment of an Assigned Interest or otherwise (each, an “Increasing Lender”): (a) represents and warrants that (i) it has full power and authority, and has taken all action necessary, to
execute and deliver this Amendment and to consummate the transactions contemplated hereby and becomes a Lender under the Credit Agreement, (ii) it meets all the requirements to be an assignee under Section 8.07(b)(iii),
(v) and (vi) of the Credit Agreement (subject to such consents, if any, as may be required under Section 8.07(b)(iii) of the Credit Agreement), (iii) from and after the Effective Date, it shall be bound by
the provisions of the Credit Agreement as a Lender thereunder and shall have the obligations of a Lender thereunder, (iv) it is sophisticated with respect to decisions to acquire assets of the type represented by its Assigned Interest and
either it, or the Person exercising discretion in making its decision to acquire its Assigned Interest, is experienced in acquiring assets of such type, (v) it has received a copy of the Credit Agreement, and has received or has been accorded
the opportunity to receive copies of the most recent financial statements delivered pursuant to Section 5.01(h) thereof, as applicable, and such other documents and information as it deems appropriate to make its own credit analysis and
decision to enter into this Amendment and to purchase its Assigned Interest, (vi) it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this Amendment and to assume its Assigned Interest and (vii) attached hereto (or otherwise delivered to the Administrative Agent prior to the date hereof) is any documentation
required to be delivered by it pursuant to the terms of the Credit Agreement, if any, duly completed and executed by such Increasing Lender; and (b) agrees that (i) it will, independently and without reliance upon the Administrative Agent, any
Assignor or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Loan Documents, and (ii) it will perform in
accordance with their terms all of the obligations which by the terms of the Loan Documents are required to be performed by it as a Lender. 

“Assigned Interest” means (i) all of the respective Assignors’ rights and obligations in their respective
capacities as Lenders under the Credit Agreement and any other documents or instruments delivered pursuant thereto to the extent related to the Revolving Credit Commitments of the respective Assignors to the extent being assigned under this
Agreement and (ii) to the extent permitted to be assigned under Applicable Law, all claims, suits, causes of action and any other right of the respective Assignors (in 

  
 6 

 
their respective capacities as Lenders) against any Person, whether known or unknown, arising under or in connection with the Credit Agreement, any other documents or instruments delivered
pursuant thereto or the loan transactions governed thereby or in any way based on or related to any of the foregoing, including, but not limited to, contract claims, tort claims, malpractice claims, statutory claims and all other claims at law or in
