manifest error.

respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be
conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender

Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other
documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or
information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation

direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit E-4 on behalf of each such direct and
indirect partner; 
 (C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the

Borrower or the Administrative Agent), an electronic copy (or an original if requested by the Borrower or the Administrative Agent) of any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in U.S. federal

 Each Lender agrees that if any form or certification it previously delivered expires or becomes
obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so. 

(h) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund
of any Taxes as to which it has been indemnified pursuant to this Section (including by the payment of additional amounts pursuant to this Section), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of
indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party related to such refund and without interest (other than any interest paid
by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this subsection (plus any
penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this
subsection, in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this subsection the payment of which would place the indemnified party in a less favorable net after-Tax position than the
indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never
been paid. This subsection shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person. 

(i) Survival. Each party’s obligations under this Section shall survive the resignation or replacement of the Administrative Agent
or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.”

 Section 5. NON-IMPAIRMENT. Except as expressly provided herein, nothing in
this Amendment shall alter or affect any provision, condition, or covenant contained in any of the Loan Documents or affect or impair any rights, powers, or remedies of Lender, it being the intent of the parties hereto that the provisions of the
Loan Documents shall continue in full force and effect except as expressly modified hereby. 
 Section 6. MISCELLANEOUS
PROVISIONS. 
 a) No Waiver. No previous waiver and no failure or delay by Lender in acting with respect to the terms of the
Note or this Amendment shall constitute a waiver of any breach, default, or failure of condition under the Note, this Amendment or the obligations secured thereby. A waiver of any term of the Note, this Amendment or of any of the obligations secured
thereby must be made in writing and shall be limited to the express written terms of such waiver. 
 b) Severability. If any provision
or obligation under this Amendment and the other Loan Documents shall be determined by a court of competent jurisdiction to be invalid, illegal or unenforceable, that provision shall be deemed severed from the Loan Documents and the validity,
legality and enforceability of the remaining provisions or obligations shall remain in full force as though the invalid, illegal, or unenforceable provision had never been a part of the Loan Documents, provided, however, that if the
rate of interest or any other amount payable under the Note or this Amendment or any other Loan Document, or the right of collectability therefore, are declared to be or become invalid, illegal or unenforceable, Lender’s obligations to make
advances under the Loan Documents shall not be enforceable by Borrower. 
 c) Governing Law and Consent to Jurisdiction. This
Amendment and any claim, controversy or dispute arising under or related to this Amendment, the relationship of the parties, and/or the interpretation and enforcement of the rights and duties of the parties will be governed by, and construed and

Documents consent to the jurisdiction of any federal or state court within the State of New York having proper venue and also consent to service of process by any means authorized by New York or federal law. 

d) Headings. All article, section or other headings appearing in this Amendment and any of the other Loan Documents are for convenience
of reference only and shall be disregarded in construing this Amendment and any of the other Loan Documents. 
 e) Counterparts. To
facilitate execution, this document may be executed in as many counterparts as may be convenient or required. It shall not be necessary that the signature of, or on behalf of, each party, or that the signature of all persons required to bind any
party, appear on each counterpart. All counterparts shall collectively constitute a single document. It shall not be necessary in making proof of this document to produce or account for more than a single counterpart containing the respective
signatures of, or on behalf of, each of the parties hereto. Any signature page to any counterpart may be detached from such counterpart without impairing the legal effect of the signatures thereon and thereafter attached to another counterpart
identical thereto except having attached to it additional signature pages. 
 f) Defined Terms. Unless otherwise defined herein, each
capitalized term used in this Amendment and not defined shall have the meaning given to such term in the Credit Agreement.

 h) Use of Singular and Plural; Gender. When the identity of the parties or
other circumstances make it appropriate, the singular number includes the plural, and the masculine gender includes the feminine and/or neuter.

incorporate by reference the entire agreement of the parties with respect to the matters contemplated therein and supersede all prior negotiations or agreements, written or oral. The Loan Documents shall not be modified except by written instrument
executed by all parties. Any reference to the Loan Documents includes any amendments (including this Amendment), renewals or extensions now or hereafter approved by Administrative Agent and, as required under the Credit Agreement, Requisite Lenders
