3. Representations and Warranties. Each Obligor hereby represents and warrants to the Administrative Agent, for the
benefit of the holders of the Obligations, that: 
 (a) Ownership. Each Obligor is the legal and beneficial owner of
its Collateral and has the right to pledge, sell, assign or transfer the same. There exists no Adverse Claim with respect to the Pledged Equity of such Obligor.

Pledged Equity consisting of partnership or limited liability company interests that do not constitute Securities), to the extent such security interest can be perfected by filing under the UCC, free and clear of all Liens except for Permitted
Liens. The taking possession by the Administrative Agent of the certificated securities (if any) evidencing the Pledged Equity and all other Instruments constituting Collateral will perfect and establish the first priority of the Administrative
Agent’s security interest in all the Pledged Equity evidenced by such certificated securities and such Instruments. With respect to any Collateral consisting of a Deposit Account, Security Entitlement or held in a Securities Account, upon
execution and delivery by the applicable Obligor, the applicable depository bank or Securities Intermediary and the Administrative Agent of an agreement granting control to the Administrative Agent over such Collateral, the Administrative Agent
shall have a valid and perfected, first priority security interest in such Collateral. 
 (c) Types of Collateral.
None of the Collateral consists of, or is the Proceeds of, As-Extracted Collateral, Farm Products, Manufactured Homes or standing timber.

 4 













 (e) Authorization of Pledged Equity. All Pledged Equity is duly
authorized and validly issued, is fully paid and, to the extent applicable, nonassessable and is not subject to the preemptive rights, warrants, options or other rights to purchase of any Person, or equityholder, voting trust or similar agreements
outstanding with respect to, or property that is convertible, into, or that requires the issuance and sale of, any of the Pledged Equity, except to the extent expressly permitted under the Loan Documents. 

(f) No Other Capital Securities, Instruments, Etc. As of the Closing Date, no Obligor owns any certificated Capital
Securities in any Subsidiary that are required to be pledged and delivered to the Administrative Agent hereunder other than as set forth on Schedule 1 hereto, and all such certificated Capital Securities have been delivered to the
Administrative Agent.

the Administrative Agent in writing, none of the Collateral consisting of an interest in a partnership or a limited liability company (i) is dealt in or traded on a securities exchange or in a securities market, (ii) by its terms expressly
provides that it is a Security governed by Article 8 of the UCC, (iii) is an Investment Company Security, (iv) is held in a Securities Account or (v) constitutes a Security or a Financial Asset.

(A) the grant by such Obligor of the security interest in the Collateral granted hereby or for the execution, delivery or performance of this Agreement by such Obligor, (B) the perfection of such security interest (to the extent such
security interest can be perfected by filing under the UCC, the granting of control (to the extent required under Section 4(a) hereof) or by filing an appropriate notice with the United States Patent and Trademark Office or the United States

to financing statements, renewal financing statements, notices or any similar documents which in the Administrative Agent’s reasonable discretion would be necessary or appropriate in order to perfect and maintain perfection of the security
interests granted hereunder, such power, being coupled with an interest, being and remaining irrevocable until the Facility Termination Date has occurred. Each Obligor hereby agrees that a carbon, photographic or other reproduction of this Agreement
or any such financing statement is sufficient for filing as a financing statement by the Administrative Agent without notice thereof to such Obligor wherever the Administrative Agent may in its sole discretion desire to file the same. 

(c) Collateral Held by Warehouseman, Bailee, etc. If any Collateral is at any time in the possession or control of a

 (g) Issuance or Acquisition of Capital Securities in Partnership or
Limited Liability Company. Not without executing and delivering, or causing to be executed and delivered, to the Administrative Agent such agreements, documents and instruments as the Administrative Agent may reasonably require, issue or acquire
any Pledged Equity consisting of an interest in a partnership or a limited liability company that (i) is dealt in or traded on a securities exchange or in a securities market, (ii) by its terms expressly provides that it is a Security

security interests granted hereunder in accordance with the UCC (including authorization to describe the Collateral as “all personal property”, “all assets” or words of similar meaning). 

6. Advances. On failure of any Obligor to perform any of the covenants and agreements contained herein, or in any other
Loan Document, the Administrative Agent may, at its sole option and in its sole discretion, perform the same and in so doing may expend such sums as the Administrative Agent may reasonably deem advisable in the performance thereof, including,
without limitation, the payment of any insurance premiums, the payment of any taxes, a payment to obtain a release of a Lien or potential Lien, expenditures made in defending against any adverse claim and all other expenditures which the
Administrative Agent may make for the protection of the security hereof or which may be compelled to make by operation of Law. All such sums and amounts so expended shall be repayable by the Obligors on a joint and several basis promptly upon timely
notice thereof and demand therefor, shall constitute additional Obligations and shall bear interest from the date said amounts are expended at the Default Rate. No such performance of any covenant or agreement by the Administrative Agent on behalf
of any Obligor, and no such advance or expenditure therefor, shall relieve the Obligors of any Default or Event of Default. The Administrative Agent may make any payment hereby authorized in accordance with any bill, statement or estimate procured
from the appropriate public office or holder of the claim to be discharged without inquiry into the accuracy of such bill, statement or estimate or into the validity of any tax assessment, sale, forfeiture, tax lien, title or claim except to the
extent such payment is being contested in good faith by an Obligor in appropriate proceedings and against which adequate reserves are being maintained in accordance with GAAP. 

  
 8 













 7. Remedies. 

(a) General Remedies. Upon the occurrence of an Event of Default and during continuation thereof, the Administrative
Agent shall have, in addition to the rights and remedies provided herein, in the Loan Documents, in any other documents relating to the Obligations, or by Law (including, but not limited to, levy of attachment, garnishment and the rights and
remedies set forth in the UCC of the jurisdiction applicable to the affected Collateral), the rights and remedies of a secured party under the UCC (regardless of whether the UCC is the law of the jurisdiction where the rights and remedies are
asserted and regardless of whether the UCC applies to the affected Collateral), and further, the Administrative Agent may, with or without judicial process or the aid and assistance of others, (i) enter on any premises on which any of the
Collateral may be located and, without resistance or interference by the Obligors, take possession of the Collateral, (ii) dispose of any Collateral on any such premises, (iii) require the Obligors to assemble and make available to the
Administrative Agent at the expense of the Obligors any Collateral at any place and time designated by the Administrative Agent which is reasonably convenient to both parties, (iv) remove any Collateral from any such premises for the purpose of
effecting sale or other disposition thereof, and/or (v) without demand and without advertisement, notice, hearing or process of law, all of which each of the Obligors hereby waives to the fullest extent permitted by Law, at any place and time
or times, sell and deliver any or all Collateral held by or for it at public or private sale (which in the case of a private sale of Pledged Equity, shall be to a restricted group of purchasers who will be obligated to agree, among other things, to
acquire such securities for their own account, for investment and not with a view to the distribution or resale thereof), at any exchange or broker’s board or elsewhere, by one or more contracts, in one or more parcels, for Money, upon credit
or otherwise, at such prices and upon such terms as the Administrative Agent deems advisable, in its sole discretion (subject to any and all mandatory legal requirements). Each Obligor acknowledges that any such private sale may be at prices and on
terms less favorable to the seller than the prices and other terms which might have been obtained at a public sale and, notwithstanding the foregoing, agrees that such private sale shall be deemed to have been made in a commercially reasonable
manner and, in the case of a sale of Pledged Equity, that the Administrative Agent shall have no obligation to delay sale of any such securities for the period of time necessary to permit the issuer of such securities to register such securities for
public sale under the Securities Act of 1933. Neither the Administrative Agent’s compliance with applicable Law nor its disclaimer of warranties relating to the Collateral shall be considered to adversely affect the commercial reasonableness of
any sale. To the extent the rights of notice cannot be legally waived hereunder, each Obligor agrees that any requirement of reasonable notice shall be met if such notice, specifying the place of any public sale or the time after which any private
sale is to be made, is personally served on or mailed, postage prepaid, to the Obligors in accordance with the notice provisions of Section 11.02 of the Credit Agreement at least 10 days before the time of sale or other
event giving rise to the requirement of such notice. The Administrative Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the
time and place to which it was so adjourned. Each Obligor further acknowledges and agrees that any offer to sell any Pledged Equity which has been (i) publicly advertised on a bona fide basis in a newspaper or other publication of general
circulation in the financial community of New York, New York (to the extent that such offer may be advertised without prior registration under the Securities Act of 1933), or (ii) made privately in the manner described above shall be deemed to
involve a “public sale” under the UCC, notwithstanding that such sale may not constitute a “public offering” 

  
 9 













 
under the Securities Act of 1933, and the Administrative Agent may, in such event, bid for the purchase of such securities. The Administrative Agent shall not be obligated to make any sale or
other disposition of the Collateral regardless of notice having been given. To the extent permitted by applicable Law, any holder of Obligations may be a purchaser at any such sale. To the extent permitted by applicable Law, each of the Obligors
hereby waives all of its rights of redemption with respect to any such sale. Subject to the provisions of applicable Law, the Administrative Agent may postpone or cause the postponement of the sale of all or any portion of the Collateral by
announcement at the time and place of such sale, and such sale may, without further notice, to the extent permitted by Law, be made at the time and place to which the sale was postponed, or the Administrative Agent may further postpone such sale by
announcement made at such time and place. 
 (b) Remedies relating to Accounts. During the continuation of an Event of
Default, whether or not the Administrative Agent has exercised any or all of its rights and remedies hereunder, (i) each Obligor will promptly upon request of the Administrative Agent instruct all account debtors to remit all payments in
respect of Accounts to a mailing location selected by the Administrative Agent and (ii) the Administrative Agent shall have the right to enforce any Obligor’s rights against its customers and account debtors, and the Administrative Agent
or its designee may notify any Obligor’s customers and account debtors that the Accounts of such Obligor have been assigned to the Administrative Agent or of the Administrative Agent’s security interest therein, and may (either in its own
name or in the name of an Obligor or both) demand, collect (including without limitation by way of a lockbox arrangement), receive, take receipt for, sell, sue for, compound, settle, compromise and give acquittance for any and all amounts due or to
become due on any Account, and, in the Administrative Agent’s discretion, file any claim or take any other action or proceeding to protect and realize upon the security interest of the holders of the Obligations in the Accounts. Each Obligor
acknowledges and agrees that the Proceeds of its Accounts remitted to or on behalf of the Administrative Agent in accordance with the provisions hereof shall be solely for the Administrative Agent’s own convenience and that such Obligor shall
not have any right, title or interest in such Accounts or in any such other amounts except as expressly provided herein. Neither the Administrative Agent nor the holders of the Obligations shall have any liability or responsibility to any Obligor
for acceptance of a check, draft or other order for payment of money bearing the legend “payment in full” or words of similar import or any other restrictive legend or endorsement or be responsible for determining the correctness of any
remittance. Furthermore, during the continuation of an Event of Default, (i) the Administrative Agent shall have the right, but not the obligation, to make test verifications of the Accounts in any manner and through any medium that it
reasonably considers advisable, and the Obligors shall furnish all such assistance and information as the Administrative Agent may require in connection with such test verifications, (ii) upon the Administrative Agent’s request and at the
expense of the Obligors, the Obligors shall cause independent public accountants or others satisfactory to the Administrative Agent to furnish to the Administrative Agent reports showing reconciliations, aging and test verifications of, and trial
balances for, the Accounts and (iii) the Administrative Agent in its own name or in the name of others may communicate with account debtors on the Accounts to verify with them to the Administrative Agent’s satisfaction the existence,
amount and terms of any Accounts. 

  
 10 













 (c) Deposit Accounts. Upon the occurrence of an Event of Default and
during continuation thereof, the Administrative Agent may prevent withdrawals or other dispositions of funds in Deposit Accounts maintained with the Administrative Agent. 

(d) Access. In addition to the rights and remedies hereunder, upon the occurrence of an Event of Default and during the
continuance thereof, the Administrative Agent shall have the right to enter and remain upon the various premises of the Obligors without cost or charge to the Administrative Agent, and use the same, together with materials, supplies, books and
records of the Obligors for the purpose of collecting and liquidating the Collateral, or for preparing for sale and conducting the sale of the Collateral, whether by foreclosure, auction or otherwise. In addition, the Administrative Agent may remove
Collateral, or any part thereof, from such premises and/or any records with respect thereto, in order to effectively collect or liquidate such Collateral. 

(e) Nonexclusive Nature of Remedies. Failure by the Administrative Agent or the holders of the Obligations to exercise
any right, remedy or option under this Agreement, any other Loan Document, any other document relating to the Obligations, or as provided by Law, or any delay by the Administrative Agent or the holders of the Obligations in exercising the same,
shall not operate as a waiver of any such right, remedy or option. No waiver hereunder shall be effective unless it is in writing, signed by the party against whom such waiver is sought to be enforced and then only to the extent specifically stated,
which in the case of the Administrative Agent or the holders of the Obligations shall only be granted as provided herein. To the extent permitted by Law, neither the Administrative Agent, the holders of the Obligations, nor any party acting as
attorney for the Administrative Agent or the holders of the Obligations, shall be liable hereunder for any acts or omissions or for any error of judgment or mistake of fact or law other than their gross negligence or willful misconduct hereunder.
The rights and remedies of the Administrative Agent and the holders of the Obligations under this Agreement shall be cumulative and not exclusive of any other right or remedy which the Administrative Agent or the holders of the Obligations may have.

 (f) Retention of Collateral. In addition to the rights and remedies hereunder, the Administrative Agent may, in
compliance with Sections 9-620 and 9-621 of the UCC or otherwise complying with the requirements of applicable Law of the relevant jurisdiction, accept or retain
the Collateral in satisfaction of the Obligations. Unless and until the Administrative Agent shall have provided such notices, however, the Administrative Agent shall not be deemed to have retained any Collateral in satisfaction of any Obligations
for any reason. 
 (g) Deficiency. In the event that the proceeds of any sale, collection or realization are
insufficient to pay all amounts to which the Administrative Agent or the holders of the Obligations are legally entitled, the Obligors shall be jointly and severally liable for the deficiency, together with interest thereon at the Default Rate,
together with the costs of collection and the fees, charges and disbursements of counsel. Any surplus remaining after the full payment and satisfaction of the Obligations shall be returned to the Obligors or to whomsoever a court of competent
jurisdiction shall determine to be entitled thereto. Notwithstanding any provision to the contrary contained herein, in any other of the 

  
 11 













 
Loan Documents or in any other documents relating to the Obligations, the obligations of each Obligor under the Credit Agreement and the other Loan Documents shall be limited to an aggregate
amount equal to the largest amount that would not render such obligations subject to avoidance under Section 548 of the Bankruptcy Code of the United States or any other applicable Debtor Relief Law (including any comparable provisions of any
applicable state Law). 
 8. Rights of the Administrative Agent. 

(a) Power of Attorney. In addition to other powers of attorney contained herein, each Obligor hereby designates and
appoints the Administrative Agent, on behalf of the holders of the Obligations, and each of its designees or agents, as attorney-in-fact of such Obligor, irrevocably and
with power of substitution, with authority to take any or all of the following actions upon the occurrence and during the continuance of an Event of Default: 

(i) to demand, collect, settle, compromise, adjust, give discharges and releases, all as the Administrative Agent may
reasonably determine; 
 (ii) to commence and prosecute any actions at any court for the purposes of collecting any
Collateral and enforcing any other right in respect thereof; 
 (iii) to defend, settle or compromise any action brought and,
in connection therewith, give such discharge or release as the Administrative Agent may deem reasonably appropriate; 
 (iv)
receive, open and dispose of mail addressed to an Obligor and endorse checks, notes, drafts, acceptances, money orders, bills of lading, warehouse receipts or other instruments or documents evidencing payment, shipment or storage of the goods giving
rise to the Collateral of such Obligor on behalf of and in the name of such Obligor, or securing, or relating to such Collateral; 

(v) sell, assign, transfer, make any agreement in respect of, or otherwise deal with or exercise rights in respect of, any
Collateral or the goods or services which have given rise thereto, as fully and completely as though the Administrative Agent were the absolute owner thereof for all purposes; 

(vi) adjust and settle claims under any insurance policy relating thereto; 

(vii) execute and deliver all assignments, conveyances, statements, financing statements, renewal financing statements,
security agreements, affidavits, notices and other agreements, instruments and documents that the Administrative Agent may determine necessary in order to perfect and maintain the security interests and liens granted in this Agreement and in order
to fully consummate all of the transactions contemplated therein; 
 (viii) institute any foreclosure proceedings that the
Administrative Agent may deem appropriate; 

  
 12 













 (ix) to sign and endorse any drafts, assignments, proxies, stock powers,
verifications, notices and other documents relating to the Collateral; 
 (x) to exchange any of the Pledged Equity or other
property upon any merger, consolidation, reorganization, recapitalization or other readjustment of the issuer thereof and, in connection therewith, deposit any of the Pledged Equity with any committee, depository, transfer agent, registrar or other
designated agency upon such terms as the Administrative Agent may reasonably deem appropriate; 
 (xi) to vote for a
shareholder resolution, or to sign an instrument in writing, sanctioning the transfer of any or all of the Pledged Equity into the name of the Administrative Agent or one or more of the holders of the Obligations or into the name of any transferee
to whom the Pledged Equity or any part thereof may be sold pursuant to Section 7 hereof; 
 (xii) to pay or discharge
taxes, liens, security interests or other encumbrances levied or placed on or threatened against the Collateral; 
 (xiii) to
direct any parties liable for any payment in connection with any of the Collateral to make payment of any and all monies due and to become due thereunder directly to the Administrative Agent or as the Administrative Agent shall direct; 

(xiv) to receive payment of and receipt for any and all monies, claims, and other amounts due and to become due at any time in
respect of or arising out of any Collateral; and 
 (xv) do and perform all such other acts and things as the Administrative
Agent may reasonably deem to be necessary, proper or convenient in connection with the Collateral. 
 This power of attorney
is a power coupled with an interest and shall be irrevocable until the Facility Termination Date has occurred. The Administrative Agent shall be under no duty to exercise or withhold the exercise of any of the rights, powers, privileges and options
expressly or implicitly granted to the Administrative Agent in this Agreement, and shall not be liable for any failure to do so or any delay in doing so. The Administrative Agent shall not be liable for any act or omission or for any error of
judgment or any mistake of fact or law in its individual capacity or its capacity as attorney-in-fact except acts or omissions resulting from its gross negligence or
willful misconduct. This power of attorney is conferred on the Administrative Agent solely to protect, preserve and realize upon its security interest in the Collateral. 

(b) Assignment by the Administrative Agent. The Administrative Agent may from time to time assign the Obligations to a
successor Administrative Agent appointed in accordance with the Credit Agreement, and such successor shall be entitled to all of the rights and remedies of the Administrative Agent under this Agreement in relation thereto. 

  
 13 













 (c) The Administrative Agent’s Duty of Care. Other than the
exercise of reasonable care to assure the safe custody of the Collateral while being held by the Administrative Agent hereunder, the Administrative Agent shall have no duty or liability to preserve rights pertaining thereto, it being understood and
agreed that the Obligors shall be responsible for preservation of all rights in the Collateral, and the Administrative Agent shall be relieved of all responsibility for the Collateral upon surrendering it or tendering the surrender of it to the
Obligors. The Administrative Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Administrative
Agent accords its own property, which shall be no less than the treatment employed by a reasonable and prudent agent in the industry, it being understood that the Administrative Agent shall not have responsibility for taking any necessary steps to
preserve rights against any parties with respect to any of the Collateral. In the event of a public or private sale of Collateral pursuant to Section 7 hereof, the Administrative Agent shall have no responsibility for (i) ascertaining or
taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating to any Collateral, whether or not the Administrative Agent has or is deemed to have knowledge of such matters, or (ii) taking any steps
to clean, repair or otherwise prepare the Collateral for sale. 
 (d) Liability with Respect to Accounts. Anything
herein to the contrary notwithstanding, each of the Obligors shall remain liable under each of the Accounts to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of
any agreement giving rise to each such Account. Neither the Administrative Agent nor any holder of Obligations shall have any obligation or liability under any Account (or any agreement giving rise thereto) by reason of or arising out of this
Agreement or the receipt by the Administrative Agent or any holder of Obligations of any payment relating to such Account pursuant hereto, nor shall the Administrative Agent or any holder of Obligations be obligated in any manner to perform any of
the obligations of an Obligor under or pursuant to any Account (or any agreement giving rise thereto), to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any
performance by any party under any Account (or any agreement giving rise thereto), to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to it or to which it
may be entitled at any time or times. 
 (e) Voting and Payment Rights in Respect of the Pledged Equity. 

(i) So long as no Event of Default shall exist, each Obligor may (A) exercise any and all voting and other consensual
rights pertaining to the Pledged Equity of such Obligor or any part thereof for any purpose not inconsistent with the terms of this Agreement or the Credit Agreement and (B) receive and retain any and all dividends (other than stock dividends
and other dividends constituting Collateral which are addressed hereinabove), principal or interest paid in respect of the Pledged Equity to the extent they are allowed under the Credit Agreement; and 

  
 14 













 (ii) During the continuance of an Event of Default, (A) all rights of
an Obligor to exercise the voting and other consensual rights which it would otherwise be entitled to exercise pursuant to clause (i)(A) above shall cease and all such rights shall thereupon become vested in the Administrative Agent which shall then
have the sole right to exercise such voting and other consensual rights, (B) all rights of an Obligor to receive the dividends, principal and interest payments which it would otherwise be authorized to receive and retain pursuant to clause
(i)(B) above shall cease and all such rights shall thereupon be vested in the Administrative Agent which shall then have the sole right to receive and hold as Collateral such dividends, principal and interest payments, and (C) all dividends,
principal and interest payments which are received by an Obligor contrary to the provisions of clause (ii)(B) above shall be received in trust for the benefit of the Administrative Agent, shall be segregated from other property or funds of such
Obligor, and shall be forthwith paid over to the Administrative Agent as Collateral in the exact form received, to be held by the Administrative Agent as Collateral and as further collateral security for the Obligations. 

(f) Releases of Collateral. (i) If any Collateral shall be sold, transferred or otherwise disposed of by any
Obligor in a transaction permitted by the Credit Agreement, then the Administrative Agent, at the request and sole expense of such Obligor, shall promptly execute and deliver to such Obligor all releases and other documents, and take such other
action, reasonably necessary for the release of the Liens created hereby or by any other Collateral Document on such Collateral. (ii) The Administrative Agent may release any of the Pledged Equity from this Agreement or may substitute any of
the Pledged Equity for other Pledged Equity without altering, varying or diminishing in any way the force, effect, lien, pledge or security interest of this Agreement as to any Pledged Equity not expressly released or substituted, and this Agreement
shall continue as a first priority lien on all Pledged Equity not expressly released or substituted. 
 9. Application of
Proceeds. Upon the acceleration of the Obligations pursuant to Section 8.02 of the Credit Agreement, any payments in respect of the Obligations and any proceeds of the Collateral, when received by the Administrative
Agent or any holder of the Obligations in Money or its equivalent, will be applied in reduction of the Obligations in the order set forth in Section 8.03 of the Credit Agreement. 

10. Continuing Agreement. This Agreement shall continue to be effective or be automatically reinstated, as the case may
be, if at any time payment, in whole or in part, of any of the Obligations is rescinded or must otherwise be restored or returned by the Administrative Agent or any holder of the Obligations as a preference, fraudulent conveyance or otherwise under
any Debtor Relief Law, all as though such payment had not been made; provided that in the event payment of all or any part of the Obligations is rescinded or must be restored or returned, all reasonable costs and expenses (including without
limitation any reasonable legal fees and disbursements) incurred by the Administrative Agent or any holder of the Obligations in defending and enforcing such reinstatement shall be deemed to be included as a part of the Obligations. 

  
 15 













 11. Amendments; Waivers; Modifications, etc. This Agreement and the
provisions hereof may not be amended, waived, modified, changed, discharged or terminated except as set forth in Section 11.01 of the Credit Agreement; provided that any update or revision to Schedule 2 hereof
delivered by any Obligor shall not constitute an amendment for purposes of this Section 11 or Section 11.01 of the Credit Agreement. 

12. Successors in Interest. This Agreement shall be binding upon each Obligor, its successors and assigns and shall inure,
together with the rights and remedies of the Administrative Agent and the holders of the Obligations hereunder, to the benefit of the Administrative Agent and the holders of the Obligations and their successors and permitted assigns. 

13. Notices. All notices required or permitted to be given under this Agreement shall be in conformance with
Section 11.02 of the Credit Agreement. 
 14. Counterparts. This Agreement may be executed in
any number of counterparts, each of which when so executed and delivered shall be an original, but all of which shall constitute one and the same instrument. It shall not be necessary in making proof of this Agreement to produce or account for more
than one such counterpart. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or other electronic imaging means shall be effective as delivery of a manually executed counterpart of this Agreement. 

15. Headings. The headings of the sections hereof are provided for convenience only and shall not in any way affect the
meaning or construction of any provision of this Agreement. 
 16. Governing Law; Submission to Jurisdiction; Venue; WAIVER OF
JURY TRIAL; Acknowledgement Regarding any Supported QFCs. The terms of Sections 11.14, 11.15 and 11.21 of the Credit Agreement with respect to governing law, submission to jurisdiction, venue, waiver of jury trial and acknowledgement
regarding any Supported QFCs are incorporated herein by reference, mutatis mutandis, and the parties hereto agree to such terms. 

17. Severability. If any provision of this Agreement is determined to be illegal, invalid or unenforceable, such provision
shall be fully severable and the remaining provisions shall remain in full force and effect and shall be construed without giving effect to the illegal, invalid or unenforceable provisions. 

18. Entirety. This Agreement, the other Loan Documents and the other documents relating to the Obligations represent the
entire agreement of the parties hereto and thereto, and supersede all prior agreements and understandings, oral or written, if any, including any commitment letters or correspondence relating to the Loan Documents, any other documents relating to
the Obligations, or the transactions contemplated herein and therein. 
 19. Other Security. To the extent that any of
the Obligations are now or hereafter secured by property other than the Collateral (including, without limitation, real property and securities owned by an Obligor), or by a guarantee, endorsement or property of any other Person, then the
Administrative Agent shall have the right to proceed against such other property, guarantee or endorsement upon the occurrence of any Event of Default, and the Administrative Agent shall have the right, in its sole discretion, to determine which
rights, security, liens, security interests or remedies the Administrative Agent shall at any time pursue, relinquish, subordinate, modify or take with respect thereto, without in any way modifying or affecting any of them or the Obligations or any
of the rights of the Administrative Agent or the holders of the Obligations under this Agreement, under any other of the Loan Documents or under any other document relating to the Obligations. 

  
 16 













 20. Joinder. At any time after the date of this Agreement, one or more
additional Persons may become party hereto by executing and delivering to the Administrative Agent a Joinder Agreement. Immediately upon such execution and delivery of such Joinder Agreement (and without any further action), each such additional
Person will become a party to this Agreement as an “Obligor” and have all of the rights and obligations of an Obligor hereunder and this Agreement and the schedules hereto shall be deemed amended by such Joinder Agreement. 

21. Consent of Issuers of Pledged Equity. Each issuer of Pledged Equity party to this Agreement hereby acknowledges,
consents and agrees to the grant of the security interests in such Pledged Equity by the applicable Obligors pursuant to this Agreement, together with all rights accompanying such security interest as provided by this Agreement and applicable law,
notwithstanding any anti-assignment provisions in any operating agreement, limited partnership agreement or similar organizational or governance documents of such issuer.
