and the other Senior Note Documents, the Grantors shall have the right to possession and enjoyment of the Collateral, subject to and upon the terms hereof and of the Credit Agreement, the other Loan Documents, the Indenture and the other Senior Note

 13 

 (iii) The Grantors acknowledge and agree that Secured Parties shall have no duties with

Default shall be held by the Grantors in trust for the benefit of the Collateral and, if required by the Collateral Agent, segregated from such Grantor’s other property (provided that if the Event of Default is an Event of Default
pursuant to subsections b, g, or h of Section 9.1 of the Credit Agreement, such sums of money or property shall be immediately segregated from Grantor’s other property by Grantor, whether or not the Collateral Agent requests such
segregation);

other communication received by it in respect of any Pledged Interests, subject to Applicable Law; 
 (iv) No Grantor shall

 14 

 (v) Each Grantor agrees that it will cooperate with the Collateral Agent in obtaining all
necessary approvals and making all necessary filings under federal, state, local, or foreign law in connection with the Security Interest on the Investment Related Property or any sale or transfer thereof; and 

(vi) As to all limited liability company or partnership interests, issued under any Pledged Operating Agreement or Pledged Partnership
Agreement, each Grantor hereby represents, warrants and covenants that the Pledged Interests issued pursuant to such agreement (A) are not and shall not be dealt in or traded on securities exchanges or in securities markets, (B) do not and
will not constitute investment company securities, and (C) are not and will not be held by such Grantor in a securities account. In addition, none of the Pledged Operating Agreements, the Pledged Partnership Agreements, or any other agreements
governing any of the Pledged Interests issued under any Pledged Operating Agreement or Pledged Partnership Agreement, provide or shall provide that such Pledged Interests are securities governed by Article 8 of the Uniform Commercial Code as in
effect in any relevant jurisdiction, unless such Pledged Interests are duly certificated, endorsed and delivered to the Collateral Agent in accordance herewith; 
 (i) Real Property; Fixtures. Each Grantor covenants and agrees that (i) upon the acquisition of any fee interest in Real Property in excess of $5,000,000 in value it will promptly (and in any
event within five (5) Business Days of acquisition) notify the Collateral Agent of the acquisition of such Real Property and (ii) upon the acquisition of any fee interest in Real Property in excess of $5,000,000 in value, it will grant to
the Collateral Agent, for the benefit of the Secured Parties, a first priority Mortgage, subject to Permitted Liens, on each such acquired fee interest in Real Property now or hereafter owned by such Grantor and shall deliver such other
documentation and opinions, in form and substance reasonably satisfactory to the Collateral Agent, in connection with the grant of such Mortgage as the Collateral Agent shall request in its Permitted Discretion, including title insurance policies,
financing statements, fixture filings and environmental audits and such Grantor shall pay all recording costs, intangible taxes and other fees and costs (including attorneys’ fees and expenses) incurred in connection therewith. Each Grantor
acknowledges and agrees that, to the extent permitted by Applicable Law, all of the Collateral shall remain personal property regardless of the manner of its attachment or affixation to real property; 

(j) Transfers and Other Liens. The Grantors shall not (i) sell, assign (by operation of law or otherwise) or otherwise
dispose of, or grant any option with respect to, any of the Collateral, except as expressly permitted by the Credit Agreement and the Indenture, or (ii) create or permit to exist any Lien upon or with respect to any of the Collateral of any of
the Grantors, except for Permitted Liens. The inclusion of Proceeds in the Collateral shall not be deemed to constitute the Collateral Agent’s consent to any sale or other disposition of any of the Collateral except as expressly permitted in
this Agreement or the other Loan Documents and the Indenture or the other Senior Note Documents; 

  
 15 

 (k) General Intangibles. To the extent that any asset purchase agreement or similar
document in respect of any acquisition permitted under the Credit Agreement and the Indenture prohibits the grant of a security interest in any Grantor’s interest therein (including any provision stating that such grant would constitute a
default under, or give rise to the right to terminate, such agreement), such Grantor shall use good faith commercially reasonable efforts to secure the consent to the granting of such security interest from each counterparty thereto on or prior to
the date of consummation of such acquisition. To the extent that any other agreement (including any other Material Contract) contains any enforceable provision prohibiting the grant of a security interest in any Grantor’s interest therein
(including any provision stating that such grant would constitute a default under, or give rise to the right to terminate, such agreement), such Grantor shall use good faith commercially reasonable efforts to secure the consent to the granting of
such security interest from each counterparty thereto within 30 days of any request by the Collateral Agent to do so; provided, however, that if the applicable counterparty is an Affiliate of such Grantor, such Grantor shall be required to secure
the consent of such Affiliate to the granting of a security interest within 30 days of the Collateral Agent’s request; and 

(l) Other Actions as to Any and All Collateral. Each Grantor shall promptly (and in any event within ten (10) Business Days
of acquiring or obtaining such Collateral) notify the Collateral Agent in writing upon (i) acquiring or otherwise obtaining any Collateral after the date hereof consisting of Trademarks, Patents, Copyrights, Intellectual Property Licenses,
Investment Related Property, Chattel Paper (electronic, tangible or otherwise), documents (as defined in Article 9 of the UCC), promissory notes (as defined in the UCC), or instruments (as defined in the UCC) or (ii) any amount payable under or
in connection with any of the Collateral being or becoming evidenced after the date hereof by any Chattel Paper, documents, promissory notes, or instruments and, in each such case upon the request of the Collateral Agent and in accordance with
Section 8 hereof, promptly execute such other documents, or if applicable, deliver such Chattel Paper, other documents or certificates evidencing any such Investment Related Property in accordance with Section 6 hereof and do
such other acts or things deemed necessary or desirable by the Collateral Agent to secure, perfect, or protect the Collateral Agent’s Security Interest therein. 
 Notwithstanding anything to the contrary contained herein, the Grantors shall not be required to deliver any document or certificate or take any further action to perfect the security interest in the
Equity Interests of CoBank, ACB, so long as such Investments are not acquired through the expenditure of any cash or other assets of any Grantor, other than a one time membership fee in an amount not to exceed $1,000. 

7. Relation to Other Security Documents. The provisions of this Agreement shall be read and construed with the other Loan
Documents and the other Senior Note Documents referred to below in the manner so indicated. 
 (a) Credit Agreement;
Indenture. In the event of any conflict between any provision in this Agreement and a provision in the Credit Agreement with respect to the rights and interests of the Lender Group, such provision of this Agreement shall control. In the event of
any conflict between any provision in this Agreement and a provision in the Indenture with respect to the rights and interests of the Trustee or the Senior Note Holders, such provision of this Agreement shall control. In the event of any conflict
between any provision of this Agreement and a provision in any Additional Loan and Notes Agreement (as defined in the Intercreditor Agreement) with respect to the rights and interests of any Additional Loan and Notes Secured Parties (as defined in
the Intercreditor Agreement) such provision of this Agreement shall control. 

  
 16 

 (b) Patent, Trademark, Copyright Security Agreements. The provisions of the Copyright
Security Agreements, Trademark Security Agreements, and Patent Security Agreements are supplemental to the provisions of this Agreement, and nothing contained in the Copyright Security Agreements, Trademark Security Agreements, or the Patent
Security Agreements shall limit any of the rights or remedies of the Collateral Agent hereunder. 
 8. Further
Assurances. 
 (a) Each Grantor agrees that from time to time, at such Grantor’s own expense, such Grantor will
promptly execute and deliver all further instruments and documents, and take all further action, that may be necessary to perfect or that the Collateral Agent may reasonably request in order to secure, perfect and protect, any Security Interest
granted or purported to be granted hereby or that may be necessary to enable the Collateral Agent to exercise and enforce its rights and remedies hereunder with respect to any of the Collateral. 

(b) Each Grantor authorizes the filing by the Collateral Agent of financing or continuation statements, or amendments thereto, and such
Grantor will execute and deliver to the Collateral Agent such other instruments or notices, as may be necessary or as the Collateral Agent may request, in order to perfect and preserve the Security Interest granted or purported to be granted hereby.

 (c) Each Grantor authorizes the Collateral Agent at any time and from time to time to file, transmit, or communicate, as
applicable, financing statements and amendments (i) describing the Collateral as “all personal property of debtor”, “all assets of debtor”, “all assets of the Debtor, whether now existing or hereafter acquired” or
words of similar effect, (ii) describing the Collateral as being of equal or lesser scope or with greater detail, or (iii) that contain any information required by part 5 of Article 9 of the UCC for the sufficiency or filing office
acceptance. Each Grantor also hereby ratifies any and all financing statements or amendments previously filed by the Collateral Agent in any jurisdiction. 
 (d) Each Grantor acknowledges that it is not authorized to file any financing statement or amendment or termination statement with respect to any financing statement filed in connection with this
Agreement without the prior written consent of the Collateral Agent, subject to such Grantor’s rights under Section 9-509(d)(2) of the UCC. 
 9. FCC Licenses; State PUC Licenses; Related Collateral. 
 (a) The
Collateral Agent’s rights hereunder (and the rights of any receiver appointed by reason of the exercise of remedies hereunder) with respect to the FCC Licenses and the State PUC Licenses and any Collateral subject to such FCC Licenses and State
PUC Licenses, are expressly subject to, and limited by any obligations and/or restrictions imposed by, the Communications Act and State Telecommunication Laws, as applicable. Prior to the exercise by the Collateral Agent (or any receiver appointed
by reason of the exercise of remedies hereunder) of any power, rights, privilege, or remedy pursuant to this Agreement which requires any consent, approval, or authorization of the FCC or any other Governmental Authority, the Grantors, at the
request of the Collateral Agent, will execute and deliver, or will cause the execution and delivery of, all applications, certificates, instruments, and other documents and papers that the Collateral Agent determines may be required to obtain such
consent, approval, or authorization. Without limiting the generality of the foregoing, each such Grantor will promptly upon request by the Collateral Agent (or any such receiver so appointed) execute and deliver the appropriate portions of
applications to the FCC or any other Governmental Authority for its consent to the assignment of or the direct or indirect transfer of control of the FCC Licenses and State PUC Licenses issued to such Grantor and/or any Collateral subject to such
FCC Licenses and State PUC Licenses and use its commercially reasonable efforts, upon the request of the Collateral Agent (or any receiver so appointed) to assist in obtaining from the FCC or such other Governmental Authority the necessary consent,
approval and authorization, if any, for the assignment of or the direct or indirect transfer of control of such FCC Licenses, such State PUC Licenses, and any Collateral subject to such FCC Licenses or State PUC Licenses to the Collateral Agent or
its designee upon or following acceleration of the payment of the Secured Obligations. 

  
 17 

 (b) Notwithstanding anything to the contrary contained in this Agreement but without waiving
or limiting any obligations of any Grantor hereunder, neither the Collateral Agent nor any receiver appointed by reason of the exercise of remedies hereunder shall control, supervise, direct, or manage, or attempt to control, supervise, direct, or
manage, the business of any Grantor, in any case that would constitute or result in any assignment of any FCC License or State PUC License or any Collateral subject to such FCC Licenses or State PUC Licenses, or a direct or indirect transfer of
control of any Grantor, any FCC License or any State PUC License, whether de jure or de facto, if such assignment or such direct or indirect transfer of control would require under the Communications Laws or State Telecommunications Laws (including
the written rules and regulations promulgated thereunder) the prior approval of the FCC or any PUC without first obtaining such approval. 
 (c) Each Grantor agrees to take any action which the Collateral Agent may request in order to obtain and enjoy the full rights and benefits granted to the Collateral Agent by this Agreement, including the
use of its commercially reasonable efforts to assist in obtaining approval of the FCC or any other Governmental Authority for any action or transaction contemplated by this Agreement which is then required by law, and specifically, without
limitation, upon request following the occurrence of an Event of Default, to prepare, sign, and file (or cause to be prepared, signed, and filed) with the FCC or any PUC any portion of any application or applications for consent to the assignment or
the direct or indirect transfer of control of the FCC Licenses or State PUC Licenses or any Collateral subject to such FCC Licenses or State PUC Licenses required to be signed by such Grantor and necessary or appropriate under the Communications
Laws or State Telecommunications Laws (including the written rules and regulations promulgated thereunder) for approval of (i) any sale or transfer of any of the capital stock or other Collateral of such Grantor or any Pledged Company or
(ii) any direct or indirect transfer of control of Grantor or any Pledged Company or any FCC License or any State PUC License held by such Grantor or any Pledged Company. 
 10. Collateral Agent’s Right to Perform Contracts. Upon the occurrence and during the continuance of an Event of Default, Collateral Agent (or its designee) may proceed to perform any and all
of the obligations of any Grantor contained in any contract, lease, or other agreement and exercise any and all rights of any Grantor therein contained as fully as such Grantor itself could. 

  
 18 

 11. Collateral Agent Appointed Attorney-in-Fact. Each Grantor hereby irrevocably
appoints the Collateral Agent its attorney-in-fact, with full authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, at such time as an Event of Default has occurred and is continuing, to take any action and
to execute any instrument which the Collateral Agent may deem necessary or advisable to accomplish the purposes of this Agreement, including: 
 (a) to ask, demand, collect, sue for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in connection with the Accounts or any other Collateral of
such Grantor; 
 (b) to receive, indorse, and collect any drafts or other instruments, documents, Negotiable Collateral or
Chattel Paper; 
 (c) to file any claims or take any action or institute any proceedings which the Collateral Agent may deem
necessary or desirable for the collection of any of the Collateral of such Grantor or otherwise to enforce the rights of the Collateral Agent with respect to any of the Collateral; 

(d) to repair, alter, or supply goods, if any, necessary to fulfill in whole or in part the purchase order of any Person obligated to
such Grantor in respect of any Account of such Grantor; 
 (e) to use any Equipment, fixtures, furniture, machinery, labels,
Patents, Trademarks, trade names, URLs, domain names, industrial designs, Copyrights, Intellectual Property Licenses, advertising matter or other industrial or intellectual property rights, in advertising for sale and selling Inventory and other
Collateral and to collect any amounts due under Accounts, contracts or Negotiable Collateral of such Grantor; and 
 (f) The
Collateral Agent on behalf of the Secured Parties shall have the right, but shall not be obligated, to bring suit in its own name to enforce the Trademarks, Patents, Copyrights and Intellectual Property Licenses and, if the Collateral Agent shall
commence any such suit, the appropriate Grantor shall, at the request of the Collateral Agent, do any and all lawful acts and execute any and all proper documents required by the Collateral Agent in aid of such enforcement. 

To the extent permitted by law, each Grantor hereby ratifies all that such attorney-in-fact shall lawfully do or cause to be done by
virtue hereof. This power of attorney is coupled with an interest and shall be irrevocable until this Agreement is terminated. 

12. Collateral Agent May Perform. If any of the Grantors fails to perform any agreement contained herein (after giving effect to
all applicable grace periods), the Collateral Agent may itself perform, or cause performance of, such agreement, and the expenses of the Collateral Agent incurred in connection therewith shall be payable, jointly and severally, by the Grantors.

  
 19 

 13. Collateral Agent’s Duties. The powers conferred on the Collateral Agent
hereunder are solely to protect the Collateral Agent’s interest in the Collateral, for the benefit of the Secured Parties, and shall not impose any duty upon the Collateral Agent to exercise any such powers. Except for the safe custody of any
Collateral in the Collateral Agent’s (or its agents’ or bailees’) possession or control and the accounting for moneys actually received by it hereunder, the Collateral Agent shall have no duty as to any Collateral or as to the taking
of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral. The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its actual
possession if such Collateral is accorded treatment substantially equal to that which the Collateral Agent accords its own property. 
 14. Collection of Accounts, General Intangibles and Negotiable Collateral. At any time upon the occurrence and during the continuation of an Event of Default, the Collateral Agent or the Collateral
Agent’s designee may (a) notify Account Debtors of any Grantor that the Accounts, General Intangibles, Chattel Paper or Negotiable Collateral have been assigned to the Collateral Agent, for the benefit of the Secured Parties, or that the
Collateral Agent has a security interest therein, and (b) collect the Accounts, General Intangibles and Negotiable Collateral directly, and any collection costs and expenses shall constitute part of such Grantor’s Secured Obligations under
the Loan Documents and the Senior Note Documents. 
 15. Disposition of Pledged Interests by the Collateral Agent. None of
the Pledged Interests existing as of the date of this Agreement are, and none of the Pledged Interests hereafter acquired on the date of acquisition thereof will be, registered or qualified under the various federal or state securities laws of the
United States and disposition thereof after an Event of Default may be restricted to one or more private (instead of public) sales in view of the lack of such registration or qualification. Each Grantor understands that in connection with such
disposition, the Collateral Agent may approach only a restricted number of potential purchasers and further understands that a sale under such circumstances may yield a lower price for the Pledged Interests than if the Pledged Interests were
registered and qualified pursuant to federal and state securities laws and sold on the open market. Each Grantor, therefore, agrees that: (a) if the Collateral Agent shall, pursuant to the terms of this Agreement, sell or cause the Pledged
Interests or any portion thereof to be sold at a private sale, the Collateral Agent shall have the right to rely upon the advice and opinion of any nationally recognized brokerage or investment firm (but shall not be obligated to seek such advice
and the failure to do so shall not be considered in determining the commercial reasonableness of such action) as to the best manner in which to offer the Pledged Interest or any portion thereof for sale and as to the best price reasonably obtainable
at the private sale thereof; and (b) such reliance shall be conclusive evidence that the Collateral Agent has handled the disposition in a commercially reasonable manner. 

  
 20 

 16. Voting Rights. 

(a) Upon the occurrence and during the continuation of an Event of Default, (i) the Collateral Agent may, at its option, and with
prior notice to any Grantor, and in addition to all rights and remedies available to the Collateral Agent under any other agreement, at law, in equity, or otherwise, exercise all voting rights, and all other ownership or consensual rights in respect
of the Pledged Interests owned by such Grantor, but under no circumstances is the Collateral Agent obligated by the terms of this Agreement to exercise such rights, (ii) if the Collateral Agent duly exercises its right to vote any of such
Pledged Interests, each Grantor hereby appoints the Collateral Agent, such Grantor’s true and lawful attorney-in-fact and IRREVOCABLE PROXY to vote such Pledged Interests in any manner the Collateral Agent deems advisable for or against all
matters submitted or which may be submitted to a vote of shareholders, partners or members, as the case may be and (iii) each Grantor shall be entitled to receive and retain any and all dividends, interest and other distributions paid in
respect of the Pledged Interests of such Grantor if and to the extent that the payment thereof is not otherwise prohibited by the terms of the Loan and Notes Agreements; provided, however, that any and all (A) dividends, interest
and other distributions paid or payable other than in cash in respect of, and instruments and other property received, receivable or otherwise distributed in respect of, or in exchange for, any Pledged Interests, (B) dividends and other
distributions paid or payable in cash in respect of any Pledged Interests in connection with a partial or total liquidation or dissolution or in connection with a reduction of capital, capital surplus or paid in surplus and (C) cash paid,
payable or otherwise distributed in respect of principal of, or in redemption of, or in exchange for, any Pledged Interests, in each case, if requested by the Collateral Agent, shall be, and shall be forthwith delivered to the Collateral Agent to
hold as Pledged Interests in accordance with the terms of the Intercreditor Agreement (provided that if the Event of Default is an Event of Default pursuant to subsections b, g, or h of Section 9.1 of the Credit Agreement, such dividends
or cash shall be delivered to Collateral Agent to hold as Pledged Interests in accordance with the terms of the Intercreditor Agreement, whether or not the Collateral Agent requests such delivery) and shall, if received by such Grantor, be received
in trust for the benefit of the Collateral Agent, and if requested by the Collateral Agent in its Permitted Discretion, be segregated from the other property or funds of such Grantor and be forthwith delivered to the Collateral Agent as Pledged
Interests in accordance with the terms of the Intercreditor Agreement in the same form as so received (with any necessary indorsement) (provided that if the Event of Default is an Event of Default pursuant to subsections b, g, or h of
Section 9.1 of the Credit Agreement, such cash or dividends shall be immediately segregated from Grantor’s other property by Grantor, whether or not the Collateral Agent requests such segregation). The power-of-attorney granted hereby is
coupled with an interest and shall be irrevocable. 
 (b) For so long as any Grantor shall have the right to vote the Pledged
Interests owned by it, such Grantor covenants and agrees that it will not, without the prior written consent of the Collateral Agent, vote or take any consensual action with respect to such Pledged Interests which would (i) affect the grant,
perfection or priority of the Liens granted to the Collateral Agent and the Secured Parties, (ii) materially diminish the value of the Collateral, taken as a whole, or (iii) affect the ability of the Collateral Agent or any of the Secured
Parties to realize or foreclose on the Collateral. 

  
 21 

 17. Remedies. Upon the occurrence and during the continuance of an Event of Default:

 (a) The Collateral Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for
herein, in the other Loan Documents, in the other Senior Note Documents or otherwise available to it, all the rights and remedies of a secured party upon default under the UCC (whether or not the UCC applies to the affected Collateral) or any other
Applicable Law. Without limiting the generality of the foregoing, each Grantor expressly agrees that, in any such event, the Collateral Agent without demand of performance or other demand, advertisement or notice of any kind (except a notice
specified below of time and place of public or private sale) to or upon any of the Grantors or any other Person (all and each of which demands, advertisements and notices are hereby expressly waived to the maximum extent permitted by the UCC or any
other Applicable Law), may take immediate possession of all or any portion of the Collateral and (i) require the Grantors to, and each Grantor hereby agrees that it will at its own expense and upon request of the Collateral Agent forthwith,
assemble all or part of the Collateral as directed by the Collateral Agent and make it available to the Collateral Agent at one or more locations where such Grantor regularly maintains Inventory or such other location as the Collateral Agent may
request, and (ii) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Collateral Agent’s offices or elsewhere, for cash, on credit, and upon such
other terms as the Collateral Agent may deem commercially reasonable. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten (10) days notice to any of the Grantors of the time and place of any public sale
or the time after which any private sale is to be made shall constitute reasonable notification and specifically such notice shall constitute a reasonable “authenticated notification of disposition” within the meaning of Section 9-611
of the UCC. the Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Collateral 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. 

(b) The Collateral Agent is hereby granted a non-exclusive license or other right to use, without liability for royalties or any other
charge, each Grantor’s labels, Patents, Copyrights, Intellectual Property Licenses, rights of use of any name, trade secrets, trade names, Trademarks, service marks and advertising matter, URLs, domain names, industrial designs, other
industrial or Intellectual Property, Equipment, fixtures, furniture, machinery or any property of a similar nature, whether owned by any of the Grantors or with respect to which any of the Grantors have rights under license, sublicense, or other
agreements, as it pertains to the Collateral, in preparing for sale, advertising for sale and selling any Collateral, and each Grantor’s rights under all licenses and all franchise agreements shall inure to the benefit of the Collateral Agent
in each case, to the extent permitted under applicable licenses or as permitted under Applicable Law. 
 (c) Any cash held by
the Collateral Agent as Collateral and all cash proceeds received by the Collateral Agent in respect of any sale of, collection from or other realization upon all or any part of the Collateral shall be applied against the Secured Obligations in the
order set forth in the Intercreditor Agreement. In the event the proceeds of Collateral are insufficient to satisfy all of the Secured Obligations in full, each Grantor shall remain jointly and severally liable for any such deficiency. 

(d) Each Grantor hereby acknowledges that the Secured Obligations arose out of one or more commercial transactions, and agrees that if an
Event of Default shall occur and be continuing the Collateral Agent shall have the right to an immediate writ of possession without notice of a hearing. The Collateral Agent shall, to the extent permitted by Applicable Law, have the right to the
appointment of a receiver for the properties and assets of each Grantor, and each Grantor hereby consents to such rights and such appointment and hereby waives any objection such Grantor may have thereto or the right to have a bond or other security
posted by the Collateral Agent. 

  
 22 

 (e) The Collateral Agent may send to each bank, securities intermediary or issuer party to
any Blocked Account Agreement an “Access Termination Notice” as defined in and under such Blocked Account Agreement. 

18. Remedies Cumulative. Each right, power, and remedy of the Collateral Agent as provided for in this Agreement, in the other
Loan Documents, in the other Senior Note Documents or now or hereafter existing at law or in equity or by statute or otherwise shall be cumulative and concurrent and shall be in addition to every other right, power, or remedy provided for in this
Agreement, in the other Loan Documents, in the other Senior Note Documents or now or hereafter existing at law or in equity or by statute or otherwise, and the exercise or beginning of the exercise by the Collateral Agent, of any one or more of such
rights, powers, or remedies shall not preclude the simultaneous or later exercise by the Collateral Agent of any or all such other rights, powers, or remedies. 
 19. Marshaling. The Collateral Agent shall not be required to marshal any present or future collateral security (including but not limited to the Collateral) for, or other assurances of payment of,
the Secured Obligations or any of them or to resort to such collateral security or other assurances of payment in any particular order, and all of its rights and remedies hereunder and in respect of such collateral security and other assurances of
payment shall be cumulative and in addition to all other rights and remedies, however existing or arising. To the extent that it lawfully may, each Grantor hereby agrees that it will not invoke any law relating to the marshaling of collateral which
might cause delay in or impede the enforcement of the Collateral Agent’s rights and remedies under this Agreement or under any other instrument creating or evidencing any of the Secured Obligations or under which any of the Secured Obligations
is outstanding or by which any of the Secured Obligations is secured or payment thereof is otherwise assured, and, to the extent that it lawfully may, each Grantor hereby irrevocably waives the benefits of all such laws. 

20. Indemnity and Expenses. 
 (a) Each Grantor agrees to, on a joint and several basis, indemnify the Collateral Agent and each Secured Party from and against all claims, lawsuits and liabilities (including attorneys’ fees)
arising out of or resulting from this Agreement (including enforcement of this Agreement), any other Loan Document or any other Senior Note Document to which such Grantor is a party, except claims, losses or liabilities resulting from the gross
negligence or willful misconduct of the party seeking indemnification as determined by a final non-appealable order of a court of competent jurisdiction; provided, that in the case of legal fees and expenses, such Grantor’s
indemnification obligations shall be limited to the reasonable and documented out-of-pocket fees, disbursements and other charges of one counsel to the Collateral Agent in any relevant jurisdiction and, in the case of any conflict of interest (as
reasonably determined by the Secured Parties, taken as a whole, affected by such conflict) one additional counsel in each relevant jurisdiction to each group of affected Secured Parties similarly situated taken as a whole. This provision shall
survive the termination of this Agreement, the Credit Agreement, the Indenture and the repayment of the Secured Obligations. 

  
 23 

 (b) The Grantors, jointly and severally, shall, upon demand, pay to the Collateral Agent all
the reasonable, documented expenses which the Collateral Agent may incur in connection with (i) the administration of this Agreement, (ii) the custody, preservation, use or operation of, or, upon an Event of Default, the sale of,
collection from, or other realization upon, any of the Collateral in accordance with this Agreement, the other Loan Documents and the other Senior Note Documents, (iii) the exercise or enforcement of any of the rights of the Collateral Agent
hereunder or (iv) the failure by any of the Grantors to perform or observe any of the provisions hereof. 
 21. Merger,
Amendments; Etc. THIS WRITTEN AGREEMENT, TOGETHER WITH THE OTHER LOAN DOCUMENTS AND THE OTHER SENIOR NOTE DOCUMENTS, REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES WITH RESPECT TO THE MATTERS ADDRESSED HEREIN AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN AGREEMENTS BETWEEN THE PARTIES. No waiver of any provision of this Agreement, and no consent to any departure by any of the Grantors herefrom,
shall in any event be effective unless the same shall be in writing and signed by the Collateral Agent, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No amendment of
any provision of this Agreement shall be effective unless the same shall be in writing and signed by the Collateral Agent and each of the Grantors to which such amendment applies. 

22. Addresses for Notices. All notices and other communications provided for hereunder shall be given in the form and manner and
delivered to the Collateral Agent at its address specified in the Credit Agreement, and to any of the Grantors at their respective addresses specified in the Credit Agreement or, as to any party, at such other address as shall be designated by such
party in a written notice to the other party. 

  
 24 

 23. Continuing Security Interest: Assignments under Credit Agreement and Indenture.
This Agreement shall create a continuing security interest in the Collateral and shall (a) remain in full force and effect until the Obligations and the Senior Secured Notes have been repaid in full in cash, or otherwise satisfied to the
satisfaction of the Secured Parties, in accordance with the provisions of the Intercreditor Agreement, the Credit Agreement, and the Indenture, and the Revolving Loan Commitment has expired or has been terminated, (b) be binding upon each of
the Grantors, and their respective successors and assigns, and (c) inure to the benefit of, and be enforceable by, the Collateral Agent, and its successors, transferees and assigns. Without limiting the generality of the foregoing clause (c),
any Lender or Senior Note Holder may, in accordance with the provisions of the Credit Agreement or the Indenture, as applicable, assign or otherwise transfer all or any portion of its rights and obligations under the Credit Agreement (including,
without limitation, all or any portion of the Revolving Loan Commitments, the Loans owing to it and any Revolving Loan Notes held by it), the Indenture or the notes issued under the Indenture, as applicable, to any other Person, and such other
Person shall thereupon become vested with all the benefits in respect thereof granted to such Lender or Senior Note Holder, as applicable, herein or otherwise. (x) Upon repayment in full in cash, or other satisfaction to the satisfaction of the
Secured Parties, of the Secured Obligations in accordance with the provisions of the Intercreditor Agreement, the Credit Agreement, and the Indenture, and the expiration or termination of the Revolving Loan Commitment, the Security Interest granted
hereby on all of the Collateral shall, and (y) upon the sale, transfer or other disposition to a non-Grantor of any portion of the Collateral (including Equity Interests in a Grantor), which sale, transfer or disposition is permitted by the
Credit Agreement and the Indenture, the Security Interest granted hereby on all of such sold, transferred or disposed Collateral (and, in the case of a sale, transfer or a disposition of Equity Interests in a Grantor other than a Borrower, that
results in such Grantor no longer being a Subsidiary of any Borrower, the Security Interest granted hereby on all of the Collateral in and to which such Grantor has any right, title or interest), shall, in each case, automatically terminate, all
without delivery of any instrument or performance of any act by any party, and all rights to the Collateral (or such portion thereof) shall revert to the Grantors or any other Person entitled thereto. At such time, the Collateral Agent will
authorize the filing of appropriate termination statements to evidence the termination of such Security Interests to the extent described above. At the request and sole expense of any Grantor following any such termination, the Collateral Agent
shall deliver to such Grantor any Pledged Collateral or other Collateral then held by the Collateral Agent hereunder in which the Security Interest has been terminated, and execute and deliver to such Grantor such documents as such Grantor shall
reasonably request to evidence such termination. Except as provided above, no transfer or renewal, extension, assignment, or termination of this Agreement, the Credit Agreement, any other Loan Document, the Indenture, any other Senior Note Document
or any other instrument or document executed and delivered by any Grantor to the Collateral Agent nor any additional Advances or other loans made by the Collateral Agent or any Lender to the Borrower, nor the taking of further security, nor the
retaking or re-delivery of the Collateral to the Grantors, or any of them, by the Collateral Agent, nor any other act of any Secured Party shall release any of Grantors from any obligation, except a release or discharge executed in writing by the
Collateral Agent in accordance with the provisions of the Credit Agreement and the Indenture. The Collateral Agent shall not by any act, delay, omission or otherwise, be deemed to have waived any of its rights or remedies hereunder, unless such
waiver is in writing and signed by the Collateral Agent and then only to the extent therein set forth. A waiver by the Collateral Agent of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or
remedy which the Collateral Agent would otherwise have had on any other occasion. 
 24. GOVERNING LAW; JURISDICTION; WAIVER
OF JURY TRIAL. 
 (a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ARE INTENDED TO TAKE EFFECT AS SEALED INSTRUMENTS
AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE CONFLICT OF LAWS PRINCIPLES THEREOF, EXCEPT TO THE EXTENT OTHERWISE PROVIDED IN THE LOAN DOCUMENTS. 

  
 25 

 (b) FOR PURPOSES OF ANY LEGAL ACTION OR PROCEEDING BROUGHT BY THE COLLATERAL AGENT WITH
RESPECT TO THIS AGREEMENT, EACH GRANTOR HEREBY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE FEDERAL AND STATE COURTS SITTING IN THE STATE OF NEW YORK AND HEREBY IRREVOCABLY DESIGNATES AND APPOINTS, AS ITS AUTHORIZED AGENT FOR SERVICE OF
PROCESS IN THE STATE OF NEW YORK, THE ADMINISTRATIVE BORROWER, OR SUCH OTHER PERSON AS SUCH GRANTOR SHALL DESIGNATE HEREAFTER BY WRITTEN NOTICE GIVEN TO THE COLLATERAL AGENT. THE SECURED PARTIES SHALL FOR ALL PURPOSES AUTOMATICALLY, AND WITHOUT ANY
ACT ON THEIR PART, BE ENTITLED TO TREAT SUCH DESIGNEE OF EACH GRANTOR AS THE AUTHORIZED AGENT TO RECEIVE FOR AND ON BEHALF OF SUCH GRANTOR SERVICE OF WRITS, OR SUMMONS OR OTHER LEGAL PROCESS IN THE STATE OF NEW YORK, WHICH SERVICE SHALL BE DEEMED
EFFECTIVE PERSONAL SERVICE ON SUCH GRANTOR SERVED WHEN DELIVERED, WHETHER OR NOT SUCH AGENT GIVES NOTICE TO SUCH GRANTOR; AND DELIVERY OF SUCH SERVICE TO ITS AUTHORIZED AGENT SHALL BE DEEMED TO BE MADE WHEN PERSONALLY DELIVERED OR THREE
(3) BUSINESS DAYS AFTER MAILING BY REGISTERED OR CERTIFIED MAIL ADDRESSED TO SUCH AUTHORIZED AGENT. EACH GRANTOR FURTHER IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED
OR CERTIFIED MAIL TO SUCH GRANTOR AT THE ADDRESS SET FORTH ABOVE, SUCH SERVICE TO BECOME EFFECTIVE THREE (3) BUSINESS DAYS AFTER SUCH MAILING. IN THE EVENT THAT, FOR ANY REASON, SUCH AGENT OR ITS SUCCESSORS SHALL NO LONGER SERVE AS AGENT OF
EACH GRANTOR TO RECEIVE SERVICE OF PROCESS IN THE STATE OF NEW YORK, EACH GRANTOR SHALL SERVE AND ADVISE THE COLLATERAL AGENT THEREOF SO THAT AT ALL TIMES EACH GRANTOR WILL MAINTAIN AN AGENT TO RECEIVE SERVICE OF PROCESS IN THE STATE OF NEW YORK ON
BEHALF OF SUCH GRANTOR WITH RESPECT TO THIS AGREEMENT, ALL OTHER LOAN DOCUMENTS, ALL OTHER SENIOR NOTE DOCUMENTS AND THE BANK PRODUCTS DOCUMENTS. IN THE EVENT THAT, FOR ANY REASON, SERVICE OF LEGAL PROCESS CANNOT BE MADE IN THE MANNER DESCRIBED
ABOVE, SUCH SERVICE MAY BE MADE IN SUCH MANNER AS PERMITTED BY LAW. 
 (c) EACH GRANTOR HEREBY IRREVOCABLY WAIVES ANY OBJECTION
IT WOULD MAKE NOW OR HEREAFTER FOR THE LAYING OF VENUE OF ANY SUIT, ACTION, OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT BROUGHT IN THE FEDERAL COURTS OF THE UNITED STATES SITTING IN NEW YORK COUNTY, NEW YORK, AND HEREBY IRREVOCABLY
WAIVES ANY CLAIM THAT ANY SUCH SUIT, ACTION, OR PROCEEDING HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. 
 (d) EACH GRANTOR AND
EACH SECURED PARTY TO THE EXTENT PERMITTED BY APPLICABLE LAW WAIVES, AND OTHERWISE AGREES NOT TO REQUEST, A TRIAL BY JURY IN ANY COURT AND IN ANY ACTION, PROCEEDING OR COUNTERCLAIM OF ANY TYPE IN WHICH ANY GRANTOR, ANY SECURED PARTY OR ANY OF THEIR
RESPECTIVE SUCCESSORS OR ASSIGNS IS A PARTY, AS TO ALL MATTERS AND THINGS ARISING DIRECTLY OR INDIRECTLY OUT OF THIS AGREEMENT. 

  
 26 

 25. New Subsidiaries. Pursuant to Section 6.16 of the Credit Agreement and
Section 4.08 of the Indenture, certain new direct or indirect Domestic Subsidiaries (whether by acquisition or creation) of a Grantor may from time to time be required to enter into this Agreement by executing and delivering in favor of the
Collateral Agent a supplement to this Agreement in the form of Exhibit A attached hereto. Upon the execution and delivery of Exhibit A by any such new Domestic Subsidiary, such Domestic Subsidiary shall become a Grantor hereunder with
the same force and effect as if originally named as a Grantor herein. The execution and delivery of any instrument adding an additional Grantor as a party to this Agreement shall not require the consent of any Grantor hereunder. The rights and
obligations of each Grantor hereunder shall remain in full force and effect notwithstanding the addition of any new Grantor hereunder. 
 26. Collateral Agent. Each reference herein to any right granted to, benefit conferred upon or power exercisable by the “Collateral Agent” shall be a reference to the Collateral Agent,
for the benefit of the Secured Parties. 
 27. Intercreditor Agreement. Notwithstanding anything herein to the contrary,
the priority of the Lien granted to the Collateral Agent under this Agreement and the exercise of the rights and remedies of the Collateral Agent hereunder and under any other Loan Documents and Senior Note Documents are subject to the provisions of
the Intercreditor Agreement. In the event of any conflict between the terms of the Intercreditor Agreement and this Agreement or any other Loan Document or Senior Note Document, the terms of the Intercreditor Agreement shall govern and control.

 28. Miscellaneous. 
 (a) This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all
of which, when taken together, shall constitute but one and the same Agreement. Delivery of an executed counterpart of this Agreement by telefacsimile or other electronic method of transmission shall be equally as effective as delivery of an
original executed counterpart of this Agreement. Any party delivering an executed counterpart of this Agreement by facsimile or other electronic method of transmission also shall deliver an original executed counterpart of this Agreement but the
failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Agreement. 
 (b) Any provision of this Agreement which is prohibited or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof in
that jurisdiction or affecting the validity or enforceability of such provision in any other jurisdiction. 
 (c) Headings used
in this Agreement are for convenience only and shall not be used in connection with the interpretation of any provision hereof. 

(d) The pronouns used herein shall include, when appropriate, either gender and both singular and plural, and the grammatical
construction of sentences shall conform thereto. 

  
 27 

 (e) Unless the context of this Agreement, any other Loan Document or any other Senior Note
Document clearly requires otherwise, references to the plural include the singular, references to the singular include the plural, the terms “includes” and “including” are not limiting, and the term “or” has, except
where otherwise indicated, the inclusive meaning represented by the phrase “and/or.” The words “hereof,” “herein,” “hereby,” “hereunder,” and similar terms in this Agreement, any other Loan Document
or any other Senior Note Document refer to this Agreement, such other Loan Document or such other Senior Note Document, as the case may be, as a whole and not to any particular provision of this Agreement, such other Loan Document or such other
Senior Note Document, as the case may be. Section, subsection, clause, schedule, and exhibit references herein are to this Agreement unless otherwise specified. Any reference in this Agreement, in any other Loan Document or any other Senior Note
Document to any agreement, instrument, or document shall include all alterations, amendments, changes, extensions, modifications, renewals, replacements, substitutions, joinders, and supplements, thereto and thereof, as applicable (subject to any
restrictions on such alterations, amendments, changes, extensions, modifications, renewals, replacements, substitutions, joinders, and supplements set forth herein). Any reference herein, in any other Loan Document or any other Senior Note Document
to the satisfaction or repayment in full of the Obligations and the Senior Secured Notes shall mean the repayment in full in cash (or cash collateralization in accordance with the terms hereof) of all Obligations and the Senior Secured Notes other
than unasserted contingent indemnification Obligations and Senior Secured Notes. Any reference herein to any Person shall be construed to include such Person’s successors and assigns. Any requirement of a writing contained herein, in any other
Loan Document or any other Senior Note Document shall be satisfied by the transmission of a Record and any Record so transmitted shall constitute a representation and warranty as to the accuracy and completeness of the information contained therein.
