Working Capital for such fiscal year, and (vi the aggregate net amount of non-cash gain on the Disposition of Property by the Borrower and its Subsidiaries during such fiscal year (other than sales of inventory in the ordinary course of business),

day, the rate per annum equal to the weighted average of the rates on overnight federal funds transactions with members of the Federal Reserve System arranged by federal funds brokers on such day, as published by the Federal Reserve Bank of New York

thereto, provides for one or more automatic increases in the stated amount thereof, the amount of such Letter of Credit shall be deemed to be the maximum stated amount of such Letter of Credit after giving effect to all such increases, whether or
not such maximum stated amount is in effect at such time.

3.7 The following is added immediately to the end of Section 3.4(d):

upon demand by the Swingline Lender plus interest thereon from the date of such demand to the date such amount is returned, at a rate per
annum equal to the Federal Funds Effective Rate. The obligations of the Lenders under this clause shall survive the payment in full of the Loans and other amounts owing under the Loan Documents and the termination of this Agreement.

3.8 The following is added to the end of Section 3.7(b):

or would violate one or more policies of the Issuing Lender applicable to borrowers generally or if at the time of such issuance a default of any Revolving Lenders obligations to fund under
Section 3.10 exists or any Revolving Lender is at such time a Defaulting Lender hereunder, unless the Issuing Lender has entered into satisfactory arrangements with the Borrower or such Revolving Lender to eliminate the Issuing
Lenders risk with respect to such Revolving Lender.

3.9 In Section 3.7 new clauses (c), (d) and (e) are
added to read as follows:

(c) The Issuing Lender shall be under no obligation to amend any Letter of Credit if (i) the
Issuing Lender would have no obligation at such time to issue such Letter of Credit in its amended form under the terms hereof, or (ii) the beneficiary of such Letter of Credit does not accept the proposed amendment to such Letter of Credit.

(d) Unless otherwise expressly agreed by the Issuing Lender and the Borrower when a Letter of Credit is, (i) the rules of
the ISP shall apply to each standby Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce at the time of issuance shall apply to
each commercial Letter of Credit. For all purposes of this Agreement, if on any date of determination a Letter of Credit has expired by its terms but any amount may still be drawn thereunder by reason of the operation of Rule 3.14 of the ISP,
such Letter of Credit shall be deemed to be outstanding in the amount so remaining available to be drawn.



6



---

(e) The Issuing Lender shall act on behalf of the Lenders with respect to any Letters of
Credit issued by it and the documents associated therewith, and the Issuing Lender shall have all of the benefits and immunities (A) provided to the Senior Administrative Agent in Article IX with respect to any acts taken or
omissions suffered by the Issuing Lender in connection with Letters of Credit issued by it or proposed to be issued by it and Applications pertaining to such Letters of Credit as fully as if the term Administrative Agent as used in
Article IX included the Issuing Lender with respect to such acts or omissions, and (B) as additionally provided herein with respect to the Issuing Lender.

3.10 In Section 3.8 (x) the phrase (with a copy to the Senior Administrative Agent) is added in the first sentence
immediately after delivering to the Issuing Lender, (y) (a) is added immediately prior to the existing paragraph and (z) new clauses (b) and (c) are added to read as follows:

(b) If the Borrower so requests in any Application, the Issuing Lender may, in its sole and absolute discretion, agree to issue a Letter of
Credit that has automatic extension provisions (each, an Auto-Extension Letter of Credit); provided that any such Auto-Extension Letter of Credit must permit the Issuing Lender to prevent any such extension at least once in
each twelve-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the Non-Extension Notice Date) in each such twelve-month period to be
agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by the Issuing Lender, the Borrower shall not be required to make a specific request to the Issuing Lender for any such extension. Once an Auto-Extension Letter of
Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) the Issuing Lender to permit the extension of such Letter of Credit at any time to an expiry date not later than the Letter of Credit Expiration Date;
provided, however, that the Issuing Lender shall not permit any such extension if (A) the Issuing Lender has determined that it would not be permitted, or would have no obligation, at such time to issue such Letter of Credit in
its revised form (as extended) under the terms hereof, or (B) it has received notice (which may be by telephone or in writing) on or before the day that is five Business Days before the Non-Extension Notice Date from the Senior Administrative
Agent, any Lender or the Borrower that one or more of the applicable conditions specified in Section 6.3 is not then satisfied, and in each such case directing the Issuing Lender not to permit such extension.

(c) If the Borrower so requests in any Application, the Issuing Lender may, in its sole and
absolute discretion, agree to issue a Letter of Credit that permits the automatic reinstatement of all or a portion of the stated amount thereof after any drawing thereunder (each, an Auto-Reinstatement Letter of Credit). Unless
otherwise directed by the Issuing Lender, the Borrower shall not be required to make a specific request to the Issuing Lender to permit such reinstatement. Once an Auto-Reinstatement Letter of Credit has been issued, except as provided in the
following sentence, the Lenders shall be deemed to have authorized (but may not require) the Issuing Lender to reinstate all or a portion of the stated amount thereof in accordance with the provisions of such Letter of Credit. Notwithstanding the
foregoing, if such Auto-Reinstatement Letter of Credit permits the Issuing Lender to decline to reinstate all or any portion of the stated amount thereof after a drawing thereunder by giving notice of such non-reinstatement within a specified number
of days after such drawing (the Non-Reinstatement Deadline), the Issuing Lender shall not permit such reinstatement if it has received a notice (which may be by telephone or in writing) on or before the day that is five Business
Days before the Non-Reinstatement Deadline from the Senior Administrative Agent, any Lender or the Borrower that one or more of the applicable conditions specified in Section 6.3 is not then satisfied and, in each case, directing the
Issuing Lender not to permit such reinstatement.

follows:

In addition, the Borrower shall pay to the Issuing Lender for its own account a fronting fee (i) with respect to
each commercial Letter of Credit, at a rate equal to 0.125% of the amount of such Letter of Credit and payable upon the issuance thereof, (ii) with respect to any amendment of a commercial Letter of Credit increasing the amount of such Letter
of Credit, at a rate separately agreed between the Borrower and the Issuing Lender, computed on the amount of such increase, and payable upon the effectiveness of such amendment, and (iii) with respect to each standby Letter of Credit, at a
rate per annum equal to 0.125% on the daily amount available to be drawn under such Letter of Credit and payable quarterly in arrears on each L/C Fee Payment Date after the Issuance Date.

3.13 The following is added immediately to the end of Section 3.10(c):

upon demand by the Issuing Lender plus interest thereon from the date of such demand to the date such amount is returned, at a rate per annum
equal to the Federal Funds Effective Rate. The obligations of the Lenders under this clause shall survive the payment in full of the Loans and other amounts owing under the Loan Documents and the termination of this Agreement.

3.14 In Section 3.11 the phrase (through the Senior Administrative Agent) is added immediately after reimburse the
Issuing Lender.

Commitments as set forth in Section 4.2(d).

three Business Days after such due date is amended to read by the required time on such due date.

3.19 In Section 7.10 in clause (c) the reference to Exhibit C is amended to read the certificate(s) delivered
pursuant to Section 6.1(c) and in clause (d)(i) the phrase or a Foreign Pledge Agreement is added immediately after Guarantee and Collateral Agreement.

paragraph is added to the end thereof:

The Borrower hereby acknowledges that (a) the Senior Administrative Agent and/or
the Lead Arranger will make available to the Lenders and the Issuing Lender materials and/or information provided by or on behalf of the Borrower hereunder (collectively, Borrower Materials) by posting the Borrower Materials on
IntraLinks or another similar electronic system (the Platform) and (b) certain of the Lenders may be public-side Lenders (i.e., Lenders that do not wish to receive material non-public information with respect to
the Borrower or its securities) (each, a Public Lender). The Borrower hereby agrees that (w) all Borrower Materials that are to be made available to Public Lenders shall be clearly and conspicuously marked PUBLIC
which, at a minimum, shall mean that the word PUBLIC shall appear prominently on the first page thereof; (x) by marking Borrower Materials PUBLIC, the Borrower shall be deemed to have authorized the Senior Administrative
Agent, the Lead Arranger, the Issuing Lender and the Lenders to treat such Borrower Materials as not containing any material non-public information with respect to the Borrower or its securities for purposes of United States Federal and state
securities laws (provided, however, that to the extent such Borrower Materials constitute Information, they shall be treated as set forth in Section 10.07); (y) all Borrower Materials marked PUBLIC are permitted to be made
available through a portion of the Platform designated Public Investor; and (z) the Senior Administrative Agent and the Lead Arranger shall be entitled to treat any Borrower Materials that are not marked PUBLIC as being
suitable only for posting on a portion of the Platform not designated Public Investor. Notwithstanding the foregoing, the Borrower shall be under no obligation to mark any Borrower Materials PUBLIC.

3.22 In Section 11.6 the following is added to the end of clause (b)(ii)(B):

10



---

3.23 In Section 11.6 a new clause (h) is added to read as follows:

(h) Resignation as Issuing Lender or Swingline Lender after Assignment. Notwithstanding anything to the contrary contained herein, if
at any time Bank of America assigns all of its Commitment and Loans pursuant to subsection (b) above, Bank of America may, (i) upon 30 days notice to the Borrower and the Lenders, resign as Issuing Lender and/or (ii) upon
30 days notice to the Borrower, resign as Swingline Lender. In the event of any such resignation as Issuing Lender or Swingline Lender, the Borrower shall be entitled to appoint from among the Lenders a successor Issuing Lender or
Swingline Lender hereunder; provided, however, that no failure by the Borrower to appoint any such successor shall affect the resignation of Bank of America as Issuing Lender or Swingline Lender, as the case may be. If Bank of America
resigns as Issuing Lender, it shall retain all the rights, powers, privileges and duties of the Issuing Lender hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as Issuing Lender and all L/C
Obligations with respect thereto (including the right to require the Lenders to make Base Rate Loans or fund risk participations in Unreimbursed Amounts pursuant to Section 3.10). If Bank of America resigns as Swingline Lender, it shall retain
all the rights of the Swingline Lender provided for hereunder with respect to Swingline Loans made by it and outstanding as of the effective date of such resignation, including the right to require the Lenders to make Base Rate Loans or fund risk
participations in outstanding Swingline Loans pursuant to Section 3.4. Upon the appointment of a successor Issuing Lender and/or Swingline Lender, (a) such successor shall succeed to and become vested with all of the rights, powers,
privileges and duties of the retiring Issuing Lender or Swingline Lender, as the case may be, and (b) the successor Issuing Lender shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such
succession or make other arrangements satisfactory to Bank of America to effectively assume the obligations of Bank of America with respect to such Letters of Credit.

3.24 New Sections 11.20 and 11.21 are added to read as follows:

11.20 Payments
Set Aside. To the extent that any payment by or on behalf of the Borrower is made to the Senior Administrative Agent, the Issuing Lender or any Lender, or the Senior Administrative Agent, the Issuing Lender or any Lender exercises its right of
setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Senior Administrative
Agent, the Issuing Lender or such Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any bankruptcy, insolvency or similar law or otherwise, then (a) to the extent of such
recovery, the



11



---

obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and
(b) each Lender and the Issuing Lender severally agrees to pay to the Senior Administrative Agent upon demand its applicable share (without duplication) of any amount so recovered from or repaid by the Senior Administrative Agent, plus interest
thereon from the date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from time to time in effect. The obligations of the Lenders and the Issuing Lender under clause (b) of the preceding
sentence shall survive the payment in full of the Obligations and the termination of this Agreement.

11.21 Obligations of
Lenders Several. The obligations of the Lenders hereunder to make Loans, to fund participations in Letters of Credit and Swingline Loans and to make payments pursuant to Section 10.11 are several and not joint. The failure of any
Lender to make any Loan, to fund any such participation or to make any payment under Section 10.11 on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender
shall be responsible for the failure of any other Lender to so make its Loan, to purchase its participation or to make its payment under Section 10.11.

4. Change in Notice Address. Bank of America, N.A., in its capacity as Administrative Agent and Collateral Agent, notifies the Loan Parties and the Lenders that its address for notices and other
communications in accordance with Section 11.2 of the Credit Agreement is as set forth on Annex 2 hereto.

5.
Conditions Precedent. This Amendment shall be effective as of the date hereof upon satisfaction of each of the following conditions precedent:

(a) Amendment. Receipt by the Senior Administrative Agent of counterparts of this Amendment executed by the Loan Parties and the Required Lenders.

(b) Assignment of Collateral. Morgan Stanley & Co. Incorporated, in its capacity as resigning Senior Collateral Agent, shall
have assigned the Collateral to Bank of America, N.A., in its capacity as successor Senior Collateral Agent, pursuant to an agreement in form and substance satisfactory to Bank of America, N.A. and shall have delivered all Collateral in its
possession to Bank of America, N.A., in its capacity as successor Senior Collateral Agent.

8. Reaffirmation of Obligations. Each Loan Party (a) acknowledges and consents to all of the terms and conditions of this
Amendment, (b) affirms all of its obligations under the Loan Documents and (c) agrees that this Amendment and all documents executed in connection herewith do not operate to reduce or discharge such Loan Partys obligations under the

granted in or pursuant to the Loan Documents are valid and subsisting and (b) agrees that this Amendment shall in no manner impair or otherwise adversely effect any of the Liens granted in or pursuant to the Loan Documents.

exhibits thereto) shall remain in full force and effect.

ANNEX 1

SECTION 10

SENIOR ADMINISTRATIVE AGENT AND SENIOR COLLATERAL AGENT



|10.1 | Appointment and Authority.
|---- | --------------------------

Each of the Lenders and the Issuing Lender hereby irrevocably appoints Bank of America to act on its behalf as the Senior Administrative Agent hereunder and under the other Loan Documents and authorizes the Senior Administrative Agent to
take such actions on its behalf and to exercise such powers as are delegated to the Senior Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this
Article are solely for the benefit of the Senior Administrative Agent, the Lenders and the Issuing Lender, and no Loan Party shall have rights as a third party beneficiary of any of such provisions.

The Senior Administrative Agent shall also act as the Senior Collateral Agent under the Loan Documents, and each of the Lenders (in its
capacities as a Lender, Swingline Lender (if applicable) and Qualifying Counterparty (if applicable)) and the Issuing Lender hereby irrevocably appoints and authorizes the Senior Administrative Agent to act as the Senior Collateral Agent for
purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Loan Parties to secure any of the Senior Obligations, together with such powers and discretion as are reasonably incidental thereto. In this
connection, the Senior Administrative Agent, acting as Senior Collateral Agent, and any co-agents, sub-agents and attorneys-in-fact appointed by the Senior Administrative Agent pursuant to Section 10.5 for purposes of holding or
enforcing any Lien on the Collateral (or any portion thereof) granted under the Loan Documents, or for exercising any rights and remedies thereunder at the direction of the Senior Administrative Agent), shall be entitled to the benefits of all
provisions of this Section 10 and Section 11 (as though such co-agents, sub-agents and attorneys-in-fact were the Senior Collateral Agent under the Loan Documents) as if set forth in full herein with respect thereto.



---

|10.2 | Rights as a Lender.
|---- | -------------------

The
Person serving as the Senior Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Senior Administrative Agent and the term
Lender or Lenders shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Senior Administrative Agent hereunder in its individual capacity. Such Person and its
Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were
not the Senior Administrative Agent hereunder and without any duty to account therefor to the Lenders.



|10.3 | Exculpatory Provisions.
|---- | -----------------------

The Senior Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, the Senior Administrative Agent:

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or Event of Default has
occurred and is continuing;

(b) shall not have any duty to take any discretionary action or exercise any
discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Senior Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other
number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Senior Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its
counsel, may expose the Senior Administrative Agent to liability or that is contrary to any Loan Document or applicable law; and

(c) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to any Loan
Party or any of its Affiliates that is communicated to or obtained by the Person serving as the Senior Administrative Agent or any of its Affiliates in any capacity.



---

The Senior Administrative Agent shall not be liable for any action taken or not taken by it
(i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Senior Administrative Agent shall believe in good faith shall be necessary, under the
circumstances as provided in Sections 11.1 and 9.1) or (ii) in the absence of its own gross negligence or willful misconduct. The Senior Administrative Agent shall be deemed not to have knowledge of any Default or Event of Default
unless and until notice describing such Default or Event of Default is given to the Senior Administrative Agent by the Borrower, a Lender or the Issuing Lender.

The Senior Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement
or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or
other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document,or
the creation, perfection or priority of any Lien purported to be created by the Collateral Documents, (v) the value or the sufficiency of any Collateral, or (vi) the satisfaction of any condition set forth in Section 6 or
elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Senior Administrative Agent.



|10.4 | Reliance by Senior Administrative Agent.
|---- | ----------------------------------------

The Senior Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other
writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Senior Administrative Agent also
may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a
Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or the Issuing Lender, the Senior Administrative Agent may presume that such condition is satisfactory to such Lender or the Issuing
Lender unless the Senior Administrative Agent shall have received notice to the contrary from such Lender or the Issuing Lender prior to the making of such Loan or the issuance of such Letter of Credit. The Senior Administrative Agent may consult
with legal counsel (who may be counsel for the Loan Parties), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or
experts.



---

|10.5 | Delegation of Duties.
|---- | ---------------------

The Senior Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Senior Administrative Agent. The
Senior Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent
and to the Related Parties of the Senior Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as
Administrative Agent.



|10.6 | Resignation of Administrative Agent.
|---- | ------------------------------------

The Senior Administrative Agent may at any time give notice of its resignation to the Lenders, the Issuing Lender and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders
shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so
appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Lenders and the
Issuing Lender, appoint a successor Administrative Agent meeting the qualifications set forth above; provided that if the Senior Administrative Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such
appointment, then such resignation shall nonetheless become effective in accordance with such notice and (a) the retiring Senior Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan
Documents (except that in the case of any collateral security held by the Senior Administrative Agent on behalf of the Lenders or the Issuing Lender under any of the Loan Documents, the retiring Senior Administrative Agent shall continue to hold
such collateral security until such time as a successor Senior Administrative Agent is appointed) and (b) all payments, communications and determinations provided to be made by, to or through the Senior Administrative Agent shall instead be
made by or to each Lender and the Issuing Lender directly, until such time as the Required Lenders appoint a successor Senior Administrative Agent as provided for above in this Section. Upon the acceptance of a successors appointment as Senior
Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Senior



---

Administrative Agent, and the retiring Senior Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already
discharged therefrom as provided above in this Section). The fees payable by the Borrower to a successor Senior Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such
successor. After the retiring Senior Administrative Agents resignation hereunder and under the other Loan Documents, the provisions of this Section 10 and Section 11.5 shall continue in effect for the benefit of such
retiring Senior Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Senior Administrative Agent was acting as Senior Administrative Agent.

Any resignation by Bank of America as Senior Administrative Agent pursuant to this Section shall also constitute its
resignation as Issuing Lender and Swingline Lender. Upon the acceptance of a successors appointment as Senior Administrative Agent hereunder, (i) such successor shall succeed to and become vested with all of the rights, powers, privileges
and duties of the retiring Issuing Lender and Swingline Lender, (ii) the retiring Issuing Lender and Swingline Lender shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and
(iii) the successor Issuing Lender shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring Issuing Lender to effectively
assume the obligations of the retiring Issuing Lender with respect to such Letters of Credit.



|10.7 | Non-Reliance on Administrative Agent and Other Lenders.
|---- | -------------------------------------------------------

Each Lender and the Issuing Lender acknowledges that it has, independently and without reliance upon the Senior Administrative Agent or any other Lender or any of their Related Parties and based on such
documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and the Issuing Lender also acknowledges that it will, independently and without reliance upon the Senior
Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based
upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.



---

|10.8 | No Other Duties; Etc.
|---- | ---------------------

Anything herein to the contrary notwithstanding, none of the bookrunners, arrangers, syndication agents, documentation agents or co-agents shall have any powers, duties or responsibilities under this Agreement or any of the other Loan
Documents, except in its capacity, as applicable, as the Senior Administrative Agent, a Lender or the Issuing Lender hereunder.



|10.9 | Senior Administrative Agent May File Proofs of Claim.
|---- | -----------------------------------------------------

In case of the pendency of any proceeding under any bankruptcy, insolvency or other debtor relief laws or any other judicial proceeding relative to any Loan Party, the Senior Administrative Agent
(irrespective of whether the principal of any Loan or L/C Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Senior Administrative Agent shall have made any demand on the
Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a) to file and
prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, L/C Obligations and all other Senior Obligations arising under the Loan Documents that are owing and unpaid and to file such other documents
as may be necessary or advisable in order to have the claims of the Lenders, the Issuing Lender and the Senior Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the
Issuing Lender and the Senior Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the Issuing Lender and the Senior Administrative Agent under Sections 3.5, 3.9 and 11.5) allowed
in such judicial proceeding; and

(b) to collect and receive any monies or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each Lender and the Issuing Lender to make such payments to the Senior Administrative Agent and, if the Senior Administrative Agent shall consent to the making of such payments
directly to the Lenders and the Issuing Lender, to pay to the Senior Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Senior Administrative Agent and its agents and counsel, and any
other amounts due the Senior Administrative Agent under Sections 3.5 and 11.6.



---

Nothing contained herein shall be deemed to authorize the Senior Administrative Agent to
authorize or consent to or accept or adopt on behalf of any Lender or the Issuing Lender any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or the Issuing Lender to authorize the
Senior Administrative Agent to vote in respect of the claim of any Lender or the Issuing Lender in any such proceeding.



|10.10 | Collateral and Guaranty Matters.
|----- | --------------------------------

The Lenders and the Issuing Lender irrevocably authorize the Senior Administrative Agent, at its option and in its discretion,

(a) to release any Lien on any property granted to or held by the Senior Administrative Agent under any Loan Document (i) upon termination of the Total Revolving Commitments and payment in full of
all Senior Obligations (other than contingent indemnification obligations) and the expiration or termination of all Letters of Credit (other than Letters of Credit as to which other arrangements satisfactory to the Senior Administrative Agent and
the Issuing Lender shall have been made), (ii) that is transferred or to be transferred as part of or in connection with any Disposition permitted hereunder or under any other Loan Document, (iii) that is owned by any Guarantor if such
Person ceases to be a Subsidiary as a result of a transaction permitted hereunder or (iv) as approved in accordance with Section 11.1;

(b) to subordinate any Lien on any property granted to or held by the Senior Administrative Agent under any Loan Document to the holder of any Lien on such property that is permitted by
Section 8.3(g); and

(c) to release any Guarantor from its obligations under the Guarantee and
Collateral Agreement if such Person ceases to be a Subsidiary as a result of a transaction permitted hereunder.



---

Upon request by the Senior Administrative Agent at any time, the Required Lenders will
confirm in writing the Senior Administrative Agents authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its obligations under the Guarantee and Collateral Agreement,
pursuant to this Section 10.10.



|10.11 | Reimbursement by Lenders.
|----- | -------------------------

To the extent that the Loan Parties for any reason fail to indefeasibly pay any amount required under Section 11.5 to be paid by them to the Senior Administrative Agent (or any sub-agent thereof), the Issuing Lender or any
Related Party of any of the foregoing, each Lender severally agrees to pay to the Senior Administrative Agent (or any such sub-agent), the Issuing Lender or such Related Party, as the case may be, such Lenders Aggregate Exposure Percentage
(determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount, provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case
may be, was incurred by or asserted against the Senior Administrative Agent (or any such sub-agent) or the Issuing Lender in its capacity as such, or against any Related Party of any of the foregoing acting for the Senior Administrative Agent (or
any such sub-agent) or Issuing Lender in connection with such capacity. The obligations of the Lenders under this subsection (c) are subject to the provisions of Section 11.20.
