3.1 Additional Representations and Warranties. As of the time when each of its Accounts arises, each Assignor shall be deemed to have represented
and warranted that each such Account, and all records, papers and documents relating thereto (if any) are genuine and what they purport to be, and that all papers and documents (if any) relating thereto (a) will, to the knowledge of such
Assignor, represent the genuine, legal, valid and binding obligation of the account debtor evidencing indebtedness unpaid and owed by the respective account debtor arising out of the performance of labor or services or the sale or lease and delivery

including, but not limited to, originals or copies of all documentation (including each Contract) with respect thereto, records of all payments received, all credits granted thereon, all merchandise returned and all other dealings therewith, and
such Assignor will make the same available on such Assignors premises to the Collateral Agent for inspection during normal business hours, at such Assignors own cost and expense, at any and all reasonable times upon reasonable prior
notice to such Assignor and otherwise in accordance with the Credit Agreement. Upon the occurrence and during the continuance of an Event of Default and at the request of the Collateral Agent, such Assignor shall, at its own cost and expense,
deliver all tangible evidence of its Accounts and Contract Rights (including, without limitation, all documents evidencing the Accounts and all Contracts) and such books and records to the Collateral Agent or to its representatives (copies of which

Collateral Agent, the Accounts and the Contracts, as well as books, records and documents (if any) of such Assignor evidencing or pertaining to such Accounts and Contracts, with an appropriate reference to the fact that such Accounts and Contracts

at its option, directly notify the obligors with respect to any Accounts and/or under any Contracts to make payments with respect thereto as provided in the
preceding clause (a), and (c) that the Collateral Agent may enforce collection of any such Accounts and Contracts and may adjust, settle or compromise the amount of payment thereof, in the same manner and to the same extent as such Assignor.
Without notice to or assent by any Assignor, the Collateral Agent may, upon the occurrence and during the continuance of an Event of Default, apply any or all amounts then in, or thereafter deposited in, the Cash Collateral Account toward the
payment of the Obligations in the manner provided in Section 7.4 of this Agreement. The reasonable costs and expenses of collection (including reasonable attorneys fees), whether incurred by an Assignor or the Collateral Agent, shall be
borne by the relevant Assignor. The Collateral Agent shall deliver a copy of each notice referred to in the preceding clause (b) to the relevant Assignor, provided that (x) the failure by the Collateral Agent to so notify such
Assignor shall not affect the effectiveness of such notice or the other rights of the Collateral Agent created by this Section 3.3 and (y) no such notice shall be required if an Event of Default of the type described in Section 11.05
of the Credit Agreement has occurred and is continuing.

3.4 Modification of Terms; etc. Except in accordance with such
Assignors ordinary course of business and consistent with reasonable business judgment or as permitted by Section 3.5(a), no Assignor shall rescind or cancel any material indebtedness evidenced by any Account or under any Contract, or
modify any material term thereof or make any material adjustment with respect thereto, or extend or renew the same, or compromise or settle any material dispute, claim, suit or legal proceeding relating thereto, or sell any Account or Contract, or

debtor named in each of its Accounts or obligor under any Contract, as and when due any and all amounts owing under or on account of such Account or Contract (including, without limitation, amounts which are delinquent, such amounts to be collected
in accordance with generally accepted lawful collection procedures) and apply forthwith upon receipt thereof all such amounts as are so collected to the outstanding balance of such Account or under such Contract. Except as otherwise directed by
the Collateral Agent after the occurrence and during the continuation of an Event of Default, any Assignor may allow in the ordinary course of business as adjustments to amounts owing under its Accounts and Contracts (i) an extension or renewal
of the time or times of payment, or settlement for less than the total unpaid balance, which such Assignor finds appropriate in accordance with reasonable business judgment and (ii) a refund or credit due as a result of returned or damaged
merchandise or improperly performed services or for other reasons which such Assignor finds appropriate in accordance with reasonable business judgment. The reasonable costs and expenses (including, without limitation, reasonable attorneys
fees) of collection, whether incurred by an Assignor or the Collateral Agent, shall be borne by the relevant Assignor. Each Assignor may assign Accounts to collection agencies in accordance with such Assignors current practices in effect on
the date hereof, to the extent permitted by the Credit Agreement.

(b) In accordance with its reasonable business judgment, at each
applicable Assignors sole cost and expense, such Assignor will appear in and defend any action or proceedings arising under, growing out of or in any manner connected with the obligations, covenants, conditions, duties, agreements or
obligations of Assignor under any Contract and/or Account of such Assignor.

Collateral Agent thereof, and upon request by the Collateral Agent will promptly deliver such Instrument to the Collateral Agent appropriately endorsed to the order of the Collateral Agent.

3.7 Assignors Remain Liable Under Accounts. (a) Anything herein to the contrary notwithstanding, the Assignors shall remain liable under each
of the Accounts to observe and perform all of the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise to such Accounts. Neither the Collateral Agent nor any other
Secured Creditor 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 Collateral Agent or any other Secured Creditor of any payment
relating to such Account pursuant hereto, nor shall the Collateral Agent or any other Secured Creditor be obligated in any manner to perform any of the obligations of any Assignor 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 them 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 them or to which they may be entitled at any time or times.

(b) Should any Assignor fail to perform or discharge its obligations or duties under the Accounts as required in Section 3.7(a) above, then the
Collateral Agent may, but shall have no obligation to (and shall not thereby release Assignor from any obligation hereunder), perform or discharge any such obligation or duty to such extent as the Collateral Agent may, in its reasonable business
judgment, deem necessary or advisable to protect the security provided hereby, including appearing in and defending any action or proceeding purporting to affect the security hereof and the rights or powers of the Collateral Agent hereunder. In
exercising any such powers, the Collateral Agent may pay necessary and reasonable costs (including reasonable attorneys and paralegals fees and expenses), and all such reasonable expenses paid or incurred by the Collateral Agent shall be
for the account of the respective Assignor and shall constitute additional Obligations of such Assignor, payable upon demand, and shall bear interest at the default rate of interest set forth in the Credit Agreement.

3.8 Assignors Remain Liable Under Contracts. (a) Anything herein to the contrary notwithstanding, the Assignors shall remain liable under
each of the Contracts to observe and perform all of the conditions and obligations to be observed and performed by them thereunder, all in accordance with and pursuant to the terms and provisions of each Contract. Neither the Collateral Agent nor
any other Secured Creditor shall have any obligation or liability under any Contract by reason of or arising out of this Agreement or the receipt by the Collateral Agent or any other Secured Creditor of any payment relating to such Contract pursuant
hereto, nor shall the Collateral Agent or any other Secured Creditor be obligated in any manner to



10



---

perform any of the obligations of any Assignor under or pursuant to any Contract, to make any payment, to make any inquiry as to the nature or the
sufficiency of any performance by any party under any Contract, 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 them or to which they may be
entitled at any time or times.

(b) Should any Assignor fail to perform or discharge its obligations or duties under the Contracts as
required in Section 3.8(a) above, then the Collateral Agent may, but shall have no obligation to (and shall not thereby release Assignor from any obligation hereunder), perform or discharge any such obligation or duty to such extent as the
Collateral Agent may, in its reasonable business judgment, deem necessary or advisable to protect the security provided hereby, including appearing in and defending any action or proceeding purporting to affect the security hereof and the rights or
powers of the Collateral Agent hereunder. In exercising any such powers, the Collateral Agent may pay necessary and reasonable costs (including reasonable attorneys and paralegals fees and expenses), and all such reasonable expenses paid
or incurred by the Collateral Agent shall be for the account of the respective Assignor and shall constitute additional Obligations of such Assignor, payable upon demand, and shall bear interest at the default rate of interest set forth in the
Credit Agreement.

3.9 Deposit Accounts; Etc. (a) No Assignor shall establish
or maintain at any time any demand, time, savings, passbook or similar account, except for such accounts maintained with a bank (as defined in Section 9-102 of the UCC) whose jurisdiction (determined in accordance with Section 9-304 of the
UCC) is within a State of the United States.Annex F hereto accurately sets forth, as of the date of this Agreement,
for each Assignor, each Deposit Account maintained by such Assignor (including a description thereof and the respective account number) and the name of the respective bank with which such Deposit Account is maintained. For each Deposit Account
(other than (i) the Cash Collateral Account, (ii) any other Deposit Account maintained with the Collateral Agent, (iii) any Excluded Account and (iv) any Minor Account), the respective Assignor shall cause the bank with which the
Deposit Account is maintained to execute and deliver to the Collateral Agent, within 60 days after the date of this Agreement (as such date may be extended by the Collateral Agent in its sole discretion) or, if later, at the time of the
establishment of the respective Deposit Account, a control agreement in the form of Annex G hereto (appropriately completed), with such changes thereto as may be reasonably acceptable to the Collateral Agent, or if after using
commercially reasonable efforts to enter into such control agreement, the respective bank refuses to enter into such control agreement, another control agreement in form and substance reasonably satisfactory to the Collateral Agent and its counsel.
Subject to Section 3.9(b), if any bank with which a Subject Deposit Account is maintained refuses to, or does not, enter into such a control agreement, then the respective Assignor shall promptly (and in any event within 60 days
after the date of this Agreement (as such date may be extended by the Collateral Agent in its sole discretion) or, if later, at the time of the establishment of such account) close the respective Subject Deposit Account and transfer all balances
therein to the Cash Collateral Account or another Subject Deposit Account meeting the requirements of this Section 3.9. If any bank with which a Subject Deposit Account is maintained refuses to subordinate all its claims with respect to such
Subject Deposit Account (other than claims for its reasonable and customary fees for administering such account) to the Collateral Agents security interest therein on terms satisfactory to the Collateral Agent, then the Collateral Agent, at
its option, may (x) require that such Subject Deposit



11



---

Account be terminated in accordance with the immediately preceding sentence or (y) agree to a control agreement without such subordination,

Subject Deposit Account listed on Annex F (other than (i) the Cash Collateral Account, (ii) any other Deposit Account maintained with the Collateral Agent and (iii) any Minor Account) hereto is maintained refuses to, or does not,
enter into a control agreement with respect to such Subject Deposit Account within 60 days after the date hereof as otherwise required pursuant to Section 3.9(a) hereof, then the applicable Assignor shall not be required to close
such Subject Deposit Account until 45 days have elapsed from the expiration of such initial 60-day period, so long as (i) such Assignor continues working in good faith to close such Subject Deposit Account within such extended 45-day period and
(ii) the average monthly balance of all Subject Deposit Accounts that are neither subject to a control agreement nor closed, in each case within such initial 60-day period, does not exceed $2,500,000 during such extended 45-day
period.

to Annex F hereto containing the relevant information with respect to the respective Deposit Account and the bank with which same is established.

estimated value thereof) of $500,000 or more, such Assignor shall promptly notify the Collateral Agent thereof in a writing signed by such Assignor and describing the details thereof and shall grant to the Collateral Agent in such writing a security
interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance reasonably satisfactory to the Collateral Agent.

be acknowledged and notarized and to record said absolute assignment with the applicable agency; (ii) take and practice or sell the Patents and Copyrights; and (iii) direct such Assignor to refrain, in which event such Assignor shall

ARTICLE VI

PROVISIONS CONCERNING ALL COLLATERAL

6.1 Protection of Collateral Agents Security. Except as
otherwise permitted by the Secured Debt Agreements, each Assignor will do nothing to impair the rights of the Collateral Agent in the Collateral. Each Assignor will at all times maintain insurance, at such Assignors own expense to the extent
and in the manner provided in the Secured Debt Agreements. Except to the extent otherwise permitted to be retained by such Assignor or applied by such Assignor pursuant to the terms of the Secured Debt Agreements, the Collateral Agent shall, at the
time any proceeds of such insurance are distributed to the Secured Creditors, apply such proceeds in accordance with Section 7.4 hereof. Each Assignor assumes all liability and responsibility in connection with the Collateral acquired by it and
the liability of such Assignor to pay the Obligations shall in no way be affected or diminished by reason of the fact that such Collateral may be lost, destroyed, stolen, damaged or for any reason whatsoever unavailable to such Assignor.

6.2 Warehouse Receipts Non-Negotiable. To the extent practicable, each Assignor agrees that if any warehouse receipt or receipt in the nature
of a warehouse receipt is issued with respect to any of its Inventory, such Assignor shall request that such warehouse receipt or receipt in the nature thereof shall not be negotiable (as such term is used in Section 7-104 of the
Uniform Commercial Code as in effect in any relevant jurisdiction or under other relevant law).

6.3 Additional Information. Each
Assignor will, at its own expense, from time to time upon the reasonable request of the Collateral Agent, promptly (and in any event within 10 days after its receipt of the respective request) furnish to the Collateral Agent such information with
respect to the Collateral (including the identity of the Collateral or such components thereof as may have been requested by the Collateral Agent, the value and location of such Collateral, etc.) as may be requested by the Collateral Agent. Without
limiting the forgoing, each Assignor agrees that it shall promptly (and in any event within 10 days after its receipt of the respective request) furnish to the Collateral Agent such updated Annexes hereto as may from time to time be reasonably
requested by the Collateral Agent.

6.4 Further Actions. Each Assignor will, at its own expense and upon the reasonable request of
the Collateral Agent, make, execute, endorse, acknowledge, file and/or deliver to the Collateral Agent from time to time such lists, descriptions and designations of its Collateral, warehouse receipts, receipts in the nature of warehouse receipts,
bills of lading, documents of title, schedules, confirmatory assignments, conveyances, financing statements, transfer endorsements, certificates, reports and other assurances or instruments and take such further steps relating to the Collateral and
other property or rights covered by the security interest hereby granted, which the Collateral Agent deems reasonably necessary to perfect, preserve or protect its security interest in the Collateral.

6.5 Financing Statements . Each Assignor agrees to execute and deliver to the Collateral Agent such financing statements, in form reasonably
acceptable to the Collateral Agent, as the Collateral Agent may from time to time reasonably request or as are reasonably



17



---

necessary or desirable in the opinion of the Collateral Agent to establish and maintain a valid, enforceable, perfected security interest in the Collateral
as provided herein and the other rights and security contemplated hereby. Each Assignor will pay any applicable filing fees, recordation taxes and related expenses relating to its Collateral. Each Assignor hereby authorizes the Collateral Agent to
file any such financing statements without the signature of such Assignor where permitted by law (and such authorization includes describing the Collateral as all assets of such Assignor or using words of similar effect).

ARTICLE VII

REMEDIES UPON OCCURRENCE OF AN
EVENT OF DEFAULT

7.1 Remedies; Obtaining the Collateral Upon Default . (a) Each Assignor agrees that, if any Event of Default
shall have occurred and be continuing, then and in every such case, the Collateral Agent, in addition to any rights now or hereafter existing under applicable law and under the other provisions of this Agreement, shall have all rights as a secured
creditor under any UCC, and such additional rights and remedies to which a secured creditor is entitled under the laws in effect in all relevant jurisdictions and may:

(i) personally, or by agents or attorneys, immediately take possession of the Collateral or any part thereof from such Assignor or any
other Person who then has possession of any part thereof with or without notice or process of law, and for that purpose may enter upon such Assignors premises where any of the Collateral is located and remove the same and use in connection
with such removal any and all services, supplies, aids and other facilities of such Assignor;

(ii) instruct the obligor or
obligors on any agreement, instrument or other obligation (including, without limitation, the Accounts and the Contracts) constituting the Collateral to make any payment required by the terms of such agreement, instrument or other obligation
directly to the Collateral Agent and may exercise any and all remedies of such Assignor in respect of such Collateral;

(iii) instruct all depository banks and/or securities intermediaries which have entered into a control agreement with the Collateral Agent to transfer all monies, Investment Property, credit balances, financial assets and Instruments held
by such depositary bank and/or securities intermediaries to the Cash Collateral Account;

(iv) sell, assign or otherwise
liquidate any or all of the Collateral or any part thereof in accordance with Section 7.2 hereof, or direct such Assignor to sell, assign or otherwise liquidate any or all of the Collateral or any part thereof, and, in each case, take
possession of the proceeds of any such sale or liquidation;

(v) take possession of the Collateral or any part thereof by
directing such Assignor in writing to deliver the same to the Collateral Agent at any reasonable place or places designated by the Collateral Agent, in which event such Assignor shall at its own expense:

(x) forthwith cause the same to be moved to the place or places so designated by the Collateral Agent and there delivered to the
Collateral Agent;



18



---

(y) store and keep any Collateral so delivered to the Collateral Agent at such place or
places pending further action by the Collateral Agent as provided in Section 7.2 hereof; and

(z) while the Collateral
shall be so stored and kept, provide such security and maintenance services as shall be reasonably necessary to protect the same and to preserve and maintain it in good condition;

(vi) license or sublicense, whether on an exclusive or nonexclusive basis, any Marks, Domain Names, Patents or Copyrights included in the
Collateral for such term and on such conditions and in such manner as the Collateral Agent shall in its sole judgment determine;

(vii) apply any monies constituting Collateral or proceeds thereof in accordance with the provisions of Section 7.4;

(viii) take any other action as specified in clauses (1) through (5), inclusive, of Section 9-607 of the UCC; and

(ix) obtain access to any Assignors data processing equipment, computer hardware and software relating to the Collateral and use all of the foregoing and the information contained therein in any manner the Collateral Agent deems
appropriate to satisfy the Obligations;

it being understood that each Assignors obligation so to deliver the Collateral is of the essence of this
Agreement and that, accordingly, upon application to a court of equity having jurisdiction, the Collateral Agent shall be entitled to a decree requiring specific performance by such Assignor of said obligation. By accepting the benefits of this
Agreement and each other Security Document, the Secured Creditors expressly acknowledge and agree that this Agreement and each other Security Document may be enforced only by the action of the Collateral Agent acting upon the instructions of the
Required Secured Creditors and that no other Secured Creditor shall have any right individually to seek to enforce or to enforce this Agreement or to realize upon the security to be granted hereby, it being understood and agreed that such rights and
remedies may be exercised by the Collateral Agent for the benefit of the Secured Creditors upon the terms of this Agreement and the other Security Documents.

(b) Without limiting the generality of the foregoing, in connection with the exercise of its remedies under this Agreement or under any of the other Credit Documents, the Collateral Agent may obtain the appointment of
a receiver or trustee to assume, upon receipt of all necessary judicial, FCC, any PUC or other Governmental Authority consents or approvals, control of or ownership of any of the Governmental Approvals to the extent permitted by, or in accordance
with, applicable law. Such receiver or trustee shall have all rights and powers provided to it by law or by court order or provided to the Collateral Agent under this Agreement or any other Credit Document. Upon the appointment of such trustee or
receiver, each Assignor



19



---

agrees to cooperate, to the extent necessary or reasonably desired by the Collateral Agent, in the expeditious preparation, execution and filing of an
application to the FCC, any PUC or any other Governmental Authority for consent to the transfer of control or assignment of any Assignors Governmental Approvals to such receiver or trustee.

(c) In connection with the enforcement by the Collateral Agent of any remedies available to it as a result of any Event of Default, each Assignor agrees
that it shall join and cooperate fully with, at the request of the Collateral Agent, any receiver referred to below and/or the successful bidder or bidders at any foreclosure sale in a filing of an application (and furnishing any additional
information that may be required in connection with such application or which the Collateral Agent may believe relevant to such application) with the FCC, any PUC and all other applicable Governmental Authorities, requesting their prior approval of
(i) the operation or abandonment of all or the portion of any System and/or (ii) the transfer of control of such Assignor or assignment of all licenses, certificates, Governmental Approvals, approvals and permits, issued to such Assignor
by the FCC, any PUC or any such Governmental Authorities with respect to any System and the operation thereof, to the Collateral Agent, the receiver or to the successful bidder or bidders. In connection with the foregoing, each Assignor shall take
such further actions, and execute all such instruments, as the Collateral Agent reasonably deems necessary or desirable. Each Assignor agrees that the Collateral Agent may enforce any obligation of such Assignor as set forth in this Section by an
action for specific performance. The exercise of any rights or remedies hereunder or under any other Credit Document by the Collateral Agent or any other Secured Creditor that may require FCC, any PUC or any other Governmental Authority approval
shall be subject to obtaining such approval. Pending the receipt of any FCC, any PUC or any other Governmental Authority approval, each Assignor shall fully cooperate with, and not do anything to delay, hinder, interfere or obstruct, such Secured
Creditors exercise of its rights in obtaining such approvals.

(d) Each Assignor expressly authorizes the Collateral Agent, and the
Collateral Agent may, but shall not be required to, at any time and from time to time, to take any and all action that it reasonably determines to be necessary or desirable to cure any default or violation (including a payment default) of such
Assignor in connection with any lease, license agreement, Governmental Approval or any other material lease, agreement or contract entered into with respect to the Systems. Any and all amounts expended by the Collateral Agent in connection with such
actions shall be for the account of such Assignor and shall constitute Obligations secured hereunder.

7.2 Remedies; Disposition of the
Collateral. If any Event of Default shall have occurred and be continuing, then any Collateral repossessed by the Collateral Agent under or pursuant to Section 7.1(a) hereof and any other Collateral whether or not so repossessed by the
Collateral Agent, may be sold, assigned, leased or otherwise disposed of under one or more contracts or as an entirety, and without the necessity of gathering at the place of sale the property to be sold, and in general in such manner, at such time
or times, at such place or places and on such terms as the Collateral Agent may, in compliance with any mandatory requirements of applicable law, determine to be commercially reasonable. Any of the Collateral may be sold, leased or otherwise
disposed of, in the condition in which the same existed when taken by the Collateral Agent or after any overhaul or repair, at the expense of the relevant Assignor, which the Collateral Agent shall determine to be commercially reasonable. Any such
sale, lease or other



20



---

disposition may be effected by means of a public disposition or private disposition, effected in accordance with the applicable requirements (in each case if
and to the extent applicable) of Sections 9-610 through 9-613 of the UCC and/or such other mandatory requirements of applicable law as may apply to the respective disposition. The Collateral Agent may, without notice or publication, adjourn any
public or private disposition or cause the same to be adjourned from time to time by announcement at the time and place fixed for the disposition, and such disposition may be made at any time or place to which the disposition may be so adjourned. To
the extent permitted by any such requirement of law, the Collateral Agent may bid for and become the purchaser (and may pay all or any portion of the purchase price by crediting Obligations against the purchase price) of the Collateral or any item
thereof, offered for disposition in accordance with this Section 7.2 without accountability to the relevant Assignor, provided that the Collateral Agent shall then notify the relevant Assignor of such purchase and the purchase price. If,
under applicable law, the Collateral Agent shall be permitted to make disposition of the Collateral within a period of time which does not permit the giving of notice to the relevant Assignor as hereinabove specified, the Collateral Agent need give
such Assignor only such notice of disposition as shall be required by such applicable law. Each Assignor agrees to do or cause to be done all such other acts and things as may be reasonably necessary to make such disposition or dispositions of all
or any portion of the Collateral valid and binding and in compliance with any and all applicable laws, regulations, orders, writs, injunctions, decrees or awards of any and all courts, arbitrators or governmental instrumentalities, domestic or
foreign, having jurisdiction over any such sale or sales, all at such Assignors expense.

7.3 Waiver of Claims. Except as
otherwise provided in this Agreement, EACH ASSIGNOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE COLLATERAL AGENTS TAKING POSSESSION OR THE COLLATERAL AGENTS DISPOSITION OF
ANY OF THE COLLATERAL, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT REMEDY OR REMEDIES, and each Assignor hereby further waives, to the extent permitted by law:

(i) all damages occasioned by such taking of possession or any such disposition except any damages which are the direct result of the
Collateral Agents gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable decision);

(ii) all other requirements as to the time, place and terms of sale or other requirements with respect to the enforcement of the Collateral Agents rights hereunder; and

(iii) all rights of redemption, appraisement, valuation, stay, extension or moratorium now or hereafter in force under any applicable law
in order to prevent or delay the enforcement of this Agreement or the absolute sale of the Collateral or any portion thereof, and each Assignor, for itself and all who may claim under it, insofar as it or they now or hereafter lawfully may, hereby
waives the benefit of all such laws.

Any sale of, or the grant of options to purchase, or any other realization upon, any Collateral shall operate to
divest all right, title, interest, claim and demand, either at law or in equity, of the



21



---

relevant Assignor therein and thereto, and shall be a perpetual bar both at law and in equity against such Assignor and against any and all Persons claiming
or attempting to claim the Collateral so sold, optioned or realized upon, or any part thereof, from, through and under such Assignor.

7.4
Application of Proceeds. (a) All moneys collected by the Collateral Agent (or, to the extent the Pledge Agreement or any other Security Document requires proceeds of collateral under such other Security Document to be applied in
accordance with the provisions of this Agreement, the Pledgee or collateral agent under such other Security Document) upon any sale or other disposition of the Collateral, together with all other moneys received by the Collateral Agent hereunder,
shall be applied as follows:

(i) first, to the payment of all amounts owing to the Collateral Agent of the type
described in clauses (iii), (iv) and (v) of the definition of Obligations;

(ii) second, to the
extent proceeds remain after the application pursuant to the preceding clause (i), an amount equal to the outstanding Primary Obligations shall be paid to the Secured Creditors as provided in Section 7.4(e) hereof, with each Secured Creditor
receiving an amount equal to its outstanding Primary Obligations or, if the proceeds are insufficient to pay in full all such Primary Obligations, its Pro Rata Share of the amount remaining to be distributed;

(iii) third, to the extent proceeds remain after the application pursuant to the preceding clauses (i) and (ii), an amount
equal to the outstanding Secondary Obligations shall be paid to the Secured Creditors as provided in Section 7.4(e) hereof, with each Secured Creditor receiving an amount equal to its outstanding Secondary Obligations or, if the proceeds are
insufficient to pay in full all such Secondary Obligations, its Pro Rata Share of the amount remaining to be distributed; and

(iv) fourth, to the extent proceeds remain after the application pursuant to the preceding clauses (i) through (iii), inclusive, and following the termination of this Agreement pursuant to Section 10.8(a) hereof, to the
relevant Assignor or to whomever may be lawfully entitled to receive such surplus.

(b) For purposes of this Agreement,
(x) Pro Rata Share shall mean, when calculating a Secured Creditors portion of any distribution or amount, that amount (expressed as a percentage) equal to a fraction the numerator of which is the then unpaid amount of
such Secured Creditors Primary Obligations or Secondary Obligations, as the case may be, and the denominator of which is the then outstanding amount of all Primary Obligations or Secondary Obligations, as the case may be,
(y) Primary Obligations shall mean (i) in the case of the Credit Document Obligations, all principal of, premium, and interest on, all Loans, all Unpaid Drawings, the Stated Amount of all outstanding Letters of Credit
and all Fees and (ii) in the case of the Other Obligations, all amounts due under each Secured Hedging Agreement (other than indemnities, fees (including, without limitation, attorneys fees) and similar obligations and liabilities) and
(z) Secondary Obligations shall mean all Obligations other than Primary Obligations.



22



---

(c) When payments to Secured Creditors are based upon their respective Pro Rata Shares, the
amounts received by such Secured Creditors hereunder shall be applied (for purposes of making determinations under this Section 7.4 only) (i) first, to their Primary Obligations and (ii) second, to their Secondary
Obligations. If any payment to any Secured Creditor of its Pro Rata Share of any distribution would result in overpayment to such Secured Creditor, such excess amount shall instead be distributed in respect of the unpaid Primary Obligations
or Secondary Obligations, as the case may be, of the other Secured Creditors, with each Secured Creditor whose Primary Obligations or Secondary Obligations, as the case may be, have not been paid in full to receive an amount equal to such excess
amount multiplied by a fraction the numerator of which is the unpaid Primary Obligations or Secondary Obligations, as the case may be, of such Secured Creditor and the denominator of which is the unpaid Primary Obligations or Secondary Obligations,

Cumulative. Each and every right, power and remedy hereby specifically given to the Collateral Agent shall be in addition to every other right, power and remedy specifically given to the Collateral Agent under this Agreement, the other Secured
Debt Agreements or now or hereafter existing at law, in equity or by statute and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time or simultaneously and as often and in
such order as may be deemed reasonable by the Collateral Agent. All such rights, powers and remedies shall be cumulative and the exercise or the beginning of the exercise of one shall not be deemed a waiver of the right to exercise any other or
others. No delay or omission of the Collateral Agent in the exercise of any such right, power or remedy and no renewal or extension of any of the Obligations shall impair any such right, power or remedy or shall be construed to be a waiver of any
Default or Event of Default or an acquiescence thereof. No notice to or demand on any Assignor in any case shall entitle it to any other or further notice or demand in similar or other circumstances or constitute a waiver of any of the rights of the
Collateral Agent to any other or further action in any circumstances without notice or demand. In the event that the Collateral Agent shall bring any suit to enforce any of its rights hereunder and shall be entitled to judgment, then in such suit
the Collateral Agent may recover reasonable expenses, including reasonable attorneys fees, and the amounts thereof shall be included in such judgment.

proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Collateral Agent, then and in every such case the relevant Assignor, the Collateral Agent and each holder of any of the Obligations
shall be restored to their former positions and rights hereunder with respect to the Collateral subject to the security interest created under this Agreement, and all rights, remedies and powers of the Collateral Agent shall continue as if no such
proceeding had been instituted.

Security, an agreement for the benefit of the Pledgee and the other Secured Creditors substantially in the form of Annex H hereto (appropriately completed to the satisfaction of the Pledgee and with such modifications, if any, as shall be

(v) with respect to any Note,
such Pledgor shall provide physical delivery of such Note to the Pledgee, endorsed in blank, or, at the request of the Pledgee, endorsed to the Pledgee; and

control within the meaning of Section 9-104 of the UCC and at any time any Default or Event of Default is in existence no withdrawals or transfers may be made therefrom by any Person except with the prior written consent of the

(i) with respect to all Collateral (other than
Minor Accounts) of such Pledgor whereby or with respect to which the Pledgee may obtain control thereof within the meaning of Section 8-106 of the UCC (or under any provision of the UCC as same may be amended or supplemented from
time to time, or under the laws of any relevant State other than the State of New York), such Pledgor shall take all actions as may be requested from time to time by the Pledgee so that control of such Collateral is obtained and at
all times held by the Pledgee, provided that, with regard to control of Security Entitlements, a Pledgor shall have 60 days after the date of this Agreement or, if later, 60 days after the establishment of the Securities Account into which
the Security Entitlement is credited, to establish such control by the Pledgee; and

(ii) each Pledgor shall
from time to time deliver to the Collateral Agent financing statements (on appropriate forms) under the Uniform Commercial Code as in effect in the various relevant States, covering all Collateral hereunder (with the form of such financing
statements to be satisfactory to the Pledgee), to be filed in the relevant filing offices so that at all times the Pledgees security interest in all Investment Property and other Collateral which can be perfected by the filing of such
financing statements (in each case to the maximum extent perfection by filing may be obtained under the laws of the relevant States, including, without limitation, Section 9-312(a) of the UCC) may be so perfected.

3.3 Subsequently Acquired Collateral. If any Pledgor shall acquire (by purchase, stock dividend, distribution or otherwise) any additional
Collateral at any time or from time to time after the date hereof, (i) such Collateral shall automatically (and without any further action being required to be taken) be subject to the pledge and security interests created pursuant to
Section 3.1 hereof and, furthermore, such Pledgor will thereafter take (or cause to be taken) all action (as promptly as practicable and, in any event, within 10 days (or 60 days as provided in Section 3.2(a)(ii) and
Section 3.2(b)(i)) after it obtains such Collateral) required with respect to such Collateral in accordance with the procedures set forth in Section 3.2 hereof, and will promptly thereafter deliver to the Pledgee (i) a certificate
executed by an authorized officer of such Pledgor describing such Collateral and certifying that the same has been duly pledged in favor of the Pledgee (for the benefit of the Secured Creditors) hereunder and (ii) supplements to Annexes A
through G hereto as are necessary to cause such Annexes to be complete and accurate at such time. Without limiting the foregoing, each Pledgor shall be required to pledge hereunder the Equity Interests of any Exempted Foreign Entity at any time and
from time to time after the date hereof acquired by such Pledgor, provided that, except in the circumstances and to the extent provided by Section 9.16 of the Credit Agreement, no Pledgor shall be required at any time to pledge hereunder
the Voting Equity Interests of any Exempted Foreign Entity constituting more than 65% of the total combined voting power of all Voting Equity Interests of such Exempted Foreign Entity. For the avoidance of doubt, notwithstanding the preceding
sentence, each Pledgor shall be required to pledge hereunder 100% of the Non-Voting Equity Interests of each Exempted Foreign Entity at any time and from time to time acquired by such Pledgor.

3.4 Transfer Taxes. Each pledge of Collateral under Section 3.1 or Section 3.3 hereof shall be accompanied by any transfer tax stamps

5. VOTING, ETC., WHILE NO EVENT OF DEFAULT OR SPECIFIED DEFAULT. Unless and until there shall have occurred and be continuing an Event of Default under
the Credit Agreement or a Default under Section 11.01 or 11.05 of the Credit Agreement (each such Default, a Specified Default), each Pledgor shall be entitled to exercise any and all voting and other consensual rights
pertaining to the Collateral owned by it, and to give consents, waivers or ratifications in respect thereof; provided that, in each case, no vote shall be cast or any



12



---

consent, waiver or ratification given or any action taken or omitted to be taken which would violate, result in a breach of any covenant contained in, or be
inconsistent with any of the terms of, any Secured Debt Agreement, or which could reasonably be expected to have the effect of impairing the value of the Collateral or any part thereof or the position or interests of the Pledgee or any other Secured
Creditor in the Collateral, unless expressly permitted by the terms of the Secured Debt Agreements. All such rights of each Pledgor to vote and to give consents, waivers and ratifications shall cease in case an Event of Default or a Specified
Default has occurred and is continuing, and Section 7 hereof shall become applicable.

6. DIVIDENDS AND OTHER DISTRIBUTIONS. Unless
and until there shall have occurred and be continuing an Event of Default, all cash dividends, cash distributions, cash Proceeds and other cash amounts payable in respect of the Collateral shall be paid to the respective Pledgor. The Pledgee shall

Nothing contained in this Section 6 shall limit or restrict in any way the Pledgees right to receive the proceeds of the Collateral in any form in accordance
with Section 3 of this Agreement. All dividends, distributions or other payments which are received by any Pledgor contrary to the provisions of this Section 6 or Section 7 hereof shall be received in trust for the benefit of the
Pledgee, shall be segregated from other property or funds of such Pledgor and shall be forthwith paid over to the Pledgee as Collateral in the same form as so received (with any necessary endorsement).

7. REMEDIES IN CASE OF AN EVENT OF DEFAULT OR A SPECIFIED DEFAULT. (a) If there shall have occurred and be continuing an Event of Default, then and
in every such case, the Pledgee shall be entitled to exercise all of the rights, powers and remedies (whether vested in it by this Agreement, any other Secured Debt Agreement or by law) for the protection and enforcement of its rights in respect of
the Collateral, and the Pledgee shall be entitled to exercise all the rights and remedies of a secured party under the UCC as in effect in any relevant jurisdiction and also shall be entitled, without limitation, to exercise the following rights,

(iv) to vote (and exercise all rights and powers in respect of voting) all or any part of the Collateral (whether or not transferred into the name of the Pledgee) and give all consents, waivers and ratifications in
respect of the Collateral and otherwise act with respect thereto as though it were the outright owner thereof (each Pledgor hereby irrevocably constituting and appointing the Pledgee the proxy and attorney-in-fact of such Pledgor, with full power of
substitution to do so);

(v) at any time and from time to time to sell, assign and deliver, or grant options to purchase,
all or any part of the Collateral, or any interest therein, at any public or private sale, without demand of performance, advertisement or notice of intention to sell or of the time or place of sale or adjournment thereof or to redeem or otherwise
purchase or dispose (all of which are hereby waived by each Pledgor), for cash, on credit or for other property, for immediate or future delivery without any assumption of credit risk, and for such price or prices and on such terms as the Pledgee in
its absolute discretion may determine, provided at least 10 days written notice of the time and place of any such sale shall be given to the respective Pledgor. The Pledgee shall not be obligated to make any such sale of Collateral
regardless of whether any such notice of sale has theretofore been given. Each Pledgor hereby waives and releases to the fullest extent permitted by law any right or equity of redemption with respect to the Collateral, whether before or after sale
hereunder, and all rights, if any, of marshalling the Collateral and any other security or the Obligations or otherwise. At any such sale, unless prohibited by applicable law, the Pledgee on behalf of the Secured Creditors may bid for and purchase
all or any part of the Collateral so sold free from any such right or equity of redemption. Neither the Pledgee nor any other Secured Creditor shall be liable for failure to collect or realize upon any or all of the Collateral or for any delay in so
doing nor shall any of them be under any obligation to take any action whatsoever with regard thereto; and

(vi) to set off
any and all Collateral against any and all Obligations, and to withdraw any and all cash or other Collateral from any and all Collateral Accounts and to apply such cash and other Collateral to the payment of any and all Obligations.

(b) If there shall have occurred and be continuing a Specified Default, then and in every such case, the Pledgee shall be entitled to vote (and exercise
all rights and powers in respect of voting) all or any part of the Collateral (whether or not transferred into the name of the Pledgee) and give all consents, waivers and ratifications in respect of the Collateral and otherwise act with respect
thereto as though it were the outright owner thereof (each Pledgor hereby irrevocably constituting and appointing the Pledgee the proxy and attorney-in-fact of such Pledgor, with full power of substitution to do so).



14



---

(c) In connection with the enforcement by the Pledgee of any remedies available to it as a result of any
Event of Default, each Pledgor agrees that it shall join and cooperate fully with, at the request of the Pledgee, any receiver referred to below and/or the successful bidder or bidders at any foreclosure sale in a filing of an application (and
furnishing any additional information that may be required in connection with such application or which the Pledgee may believe relevant to such application) with the FCC, any PUC and all other applicable Governmental Authorities, requesting their
prior approval of (i) the operation or abandonment of all or the portion of any System and/or (ii) the transfer of control of such Pledgor or assignment of all licenses, certificates, Governmental Approvals, approvals and permits, issued
to such Pledgor by the FCC, any PUC or any such Governmental Authorities with respect to any System and the operation thereof, to the Pledgee, the receiver or to the successful bidder or bidders. In connection with the foregoing, each Pledgor shall
take such further actions, and execute all such instruments, as the Pledgee reasonably deems necessary or desirable. Each Pledgor agrees that the Pledgee may enforce any obligation of such Pledgor as set forth in this Section by an action for
specific performance. The exercise of any rights or remedies hereunder or under any other Credit Document by the Pledgee or any other Secured Creditor that may require FCC, any PUC or any other Governmental Authority approval shall be subject to
obtaining such approval. Pending the receipt of any FCC, any PUC or any other Governmental Authority approval, each Pledgor shall fully cooperate with, and not do anything to delay, hinder, interfere or obstruct, such Secured Creditors
exercise of its rights in obtaining such approvals.

8. REMEDIES CUMULATIVE, ETC. Each and every right, power and remedy of the Pledgee
provided for in this Agreement or in any other Secured Debt Agreement, or now or hereafter existing at law or in equity or by statute shall be cumulative and concurrent and shall be in addition to every other such right, power or remedy. The
exercise or beginning of the exercise by the Pledgee or any other Secured Creditor of any one or more of the rights, powers or remedies provided for in this Agreement or any other Secured Debt Agreement or now or hereafter existing at law or in
equity or by statute or otherwise shall not preclude the simultaneous or later exercise by the Pledgee or any other Secured Creditor of all such other rights, powers or remedies, and no failure or delay on the part of the Pledgee or any other
Secured Creditor to exercise any such right, power or remedy shall operate as a waiver thereof. No notice to or demand on any Pledgor in any case shall entitle it to any other or further notice or demand in similar or other circumstances or
constitute a waiver of any of the rights of the Pledgee or any other Secured Creditor to any other or further action in any circumstances without notice or demand. The Secured Creditors agree that this Agreement may be enforced only by the action of
the Pledgee, in each case, acting upon the instructions of the Required Secured Creditors, and that no other Secured Creditor shall have any right individually to seek to enforce or to enforce this Agreement or to realize upon the security to be
granted hereby, it being understood and agreed that such rights and remedies may be exercised by the Pledgee for the benefit of the Secured Creditors upon the terms of this Agreement and the Security Agreement.

9. APPLICATION OF PROCEEDS. (a) All monies collected by the Pledgee upon any sale or other disposition of the Collateral pursuant to the terms of
this Agreement, together with all other monies received by the Pledgee hereunder, shall be applied in the manner provided in the Security Agreement.

to its Obligations to the extent of any deficiency between the amount of the proceeds of the Collateral pledged by it hereunder and the aggregate amount of such Obligations.

10. PURCHASERS OF COLLATERAL. Upon any sale of the Collateral by the Pledgee hereunder (whether by virtue of the power of sale herein granted, pursuant
to judicial process or otherwise), the receipt of the Pledgee or the officer making such sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold, and such purchaser or purchasers shall not be obligated to see to
the application of any part of the purchase money paid over to the Pledgee or such officer or be answerable in any way for the misapplication or nonapplication thereof.

11. INDEMNITY. Each Pledgor jointly and severally agrees (i) to indemnify, reimburse and hold harmless the Pledgee and each other Secured Creditor and their respective successors, assigns, employees, agents and
affiliates (individually an Indemnitee, and collectively, the Indemnitees) from and against any and all obligations, damages, injuries, penalties, claims, demands, losses, judgments and liabilities (including,
without limitation, liabilities for penalties) of whatsoever kind or nature, and (ii) to reimburse each Indemnitee for all reasonable costs, expenses and disbursements, including reasonable attorneys fees and expenses, in each case
arising out of or resulting from this Agreement or the exercise by any Indemnitee of any right or remedy granted to it hereunder or under any other Secured Debt Agreement (but excluding any obligations, damages, injuries, penalties, claims, demands,
losses, judgments and liabilities (including, without limitation, liabilities for penalties) or expenses of whatsoever kind or nature to the extent incurred or arising by reason of gross negligence or willful misconduct of such Indemnitee (as
determined by a court of competent jurisdiction in a final and non-appealable decision)). In no event shall the Pledgee be liable, in the absence of gross negligence or willful misconduct on its part (as determined by a court of competent
jurisdiction in a final and non-appealable decision), for any matter or thing in connection with this Agreement other than to account for monies or other property actually received by it in accordance with the terms hereof. If and to the extent that
the obligations of any Pledgor under this Section 11 are unenforceable for any reason, such Pledgor hereby agrees to make the maximum contribution to the payment and satisfaction of such obligations which is permissible under applicable law.
The indemnity obligations of each Pledgor contained in this Section 11 shall continue in full force and effect notwithstanding the full payment of all the Notes issued under the Credit Agreement, the termination of all Secured Hedging
Agreements and Letters of Credit, and the payment of all other Obligations and notwithstanding the discharge thereof.

12. PLEDGEE NOT A
PARTNER OR LIMITED LIABILITY COMPANY MEMBER. (a) Nothing herein shall be construed to make the Pledgee or any other Secured Creditor liable as a member of any limited liability company or as a partner of any partnership and neither the Pledgee
nor any other Secured Creditor by virtue of this Agreement or otherwise (except as referred to in the following sentence) shall have any of the duties, obligations or liabilities of a member of any limited liability company or as a partner in any
partnership. The



16



---

parties hereto expressly agree that, unless the Pledgee shall become the absolute owner of Collateral consisting of a Limited Liability Company Interest or a
Partnership Interest pursuant hereto, this Agreement shall not be construed as creating a partnership or joint venture among the Pledgee, any other Secured Creditor, any Pledgor and/or any other Person.

(b) Except as provided in the last sentence of paragraph (a) of this Section 12, the Pledgee, by accepting this Agreement, did not intend to
become a member of any limited liability company or a partner of any partnership or otherwise be deemed to be a co-venturer with respect to any Pledgor, any limited liability company, partnership and/or any other Person either before or after an
Event of Default shall have occurred. The Pledgee shall have only those powers set forth herein and the Secured Creditors shall assume none of the duties, obligations or liabilities of a member of any limited liability company or as a partner of any
partnership or any Pledgor except as provided in the last sentence of paragraph (a) of this Section 12.

(c) The Pledgee and the
other Secured Creditors shall not be obligated to perform or discharge any obligation of any Pledgor as a result of the pledge hereby effected.

(d) The acceptance by the Pledgee of this Agreement, with all the rights, powers, privileges and authority so created, shall not at any time or in any event obligate the Pledgee or any other Secured Creditor to appear in or defend any
action or proceeding relating to the Collateral to which it is not a party, or to take any action hereunder or thereunder, or to expend any money or incur any expenses or perform or discharge any obligation, duty or liability under the Collateral.

Pledgors own expense, deliver to the Pledgee such financing statements, continuation statements and other documents, in form reasonably acceptable to the Pledgee, as the Pledgee (acting on its own or on the instructions of the Required Secured
Creditors) may reasonably deem necessary or appropriate in order to perfect and preserve the Pledgees security interest in the Collateral hereunder and hereby authorizes the Pledgee to file financing statements and amendments thereto relative
to all or any part of the Collateral (including, without limitation, (x) financing statements which list the Collateral specifically and/or all assets as collateral and (y) in lieu of financing statements) without
the signature of such Pledgor where permitted by law, and agrees to do such further acts and things and to execute and deliver to the Pledgee such additional conveyances, assignments, agreements and instruments as the Pledgee may reasonably require

for such security interest to attach (subject, in each case, to no pledge, lien, mortgage, hypothecation, security interest, charge, option, Adverse Claim or other encumbrance whatsoever, except the liens and security interests created by this

(iv) except as (and to the extent) addressed in Section 13.18 of the Credit Agreement or to the extent already

any other Secured Debt Agreement to which it is a party, nor compliance by it with the terms and provisions hereof and thereof nor the consummation of the transactions contemplated therein: (i) will contravene any material provision of any
applicable material law, statute, rule or regulation, or any applicable material order, writ, injunction or decree of any court or governmental instrumentality; (ii) will conflict with or result in any breach of any of the terms, covenants,
conditions or provisions of, or constitute a default under, or result in the creation or imposition of (or the obligation to create or impose) any Lien (other than pursuant to the Security Documents) upon any material portion of the properties or
assets of such Pledgor or any of its Subsidiaries pursuant to the terms of any material indenture, mortgage, deed of trust, credit agreement, loan agreement or any other material agreement, contract or other instrument to which such Pledgor or any

is sought in equity or at law);

(viii) the pledge, collateral assignment and delivery to the Pledgee of such Pledgors
Collateral consisting of Certificated Securities and Pledged Notes pursuant to this Agreement creates a valid and perfected first priority security interest in such Certificated Securities and Pledged Notes and the proceeds thereof, subject to no
prior Lien or encumbrance or to any agreement purporting to grant to any third party a Lien or encumbrance on the property or assets of such Pledgor which would include the Certificated Securities or the Pledged Notes (other than the liens and
security interests permitted under the Secured Debt Agreements then in effect) and the Pledgee is entitled

to all the rights, priorities and benefits afforded by the UCC or other relevant law as enacted in any relevant jurisdiction to perfect security interests in
respect of such Collateral; and

(ix) control (as defined in Section 8-106 of the UCC) has been obtained by
the Pledgee over all of such Pledgors Collateral consisting of Securities or Security Entitlements with respect to which such control may be obtained pursuant to Section 8-106 of the UCC, except to the extent that the
obligation of the applicable Pledgor to provide the Pledgee with control of such Collateral has not yet arisen under this Agreement.

(b) Each Pledgor covenants and agrees that it will defend the Pledgees right, title and security interest in and to such Pledgors Collateral and the proceeds thereof against the claims and demands of all persons whomsoever; and
each Pledgor covenants and agrees that it will have like title to and right to pledge any other property at any time hereafter pledged to the Pledgee by such Pledgor as Collateral hereunder and will likewise defend the right thereto and security
interest therein of the Pledgee and the other Secured Creditors.

Number (if any) and whether or not such Pledgor is a Transmitting Utility, is listed on Annex A hereto for such Pledgor. No Pledgor shall change its legal name, its type of organization, its status as a Registered Organization (in the case of a
Registered Organization), its status as a Transmitting Utility or as a Person which is not a Transmitting Utility, as the case may be, its jurisdiction of organization, its Location, its organizational identification number (if any), or its Federal
Employer Identification Number (if any), except that any such changes shall be permitted (so long as not in violation of the applicable requirements of the Secured Debt Agreements and so long as same do not involve (x) a Registered Organization
ceasing to constitute same or (y) any Pledgor changing its jurisdiction of organization or Location from the United States or a State thereof to a jurisdiction of organization or Location, as the case may be, outside the United States or a
State thereof) if (i) it shall have given to the Pledgee not less than 15 days prior written notice of each change to the information listed on Annex A (as adjusted for any subsequent changes thereto previously made in accordance with
this sentence), together with a supplement to Annex A which shall correct all information contained therein for such Pledgor, and (ii) in connection with such change or changes, it shall have taken all action reasonably requested by the Pledgee
to maintain the security interest of the Pledgee in the Collateral intended to be granted hereby at all times fully perfected and in full force and effect. In addition, to the extent that any Pledgor does not have an organizational identification
number on the date hereof and later obtains one, such Pledgor shall



20



---

promptly thereafter deliver a notification of the Pledgee of such organizational identification number and shall take all actions reasonably requested by the
Pledgee to maintain the security interest of the Pledgee in the Collateral intended to be granted hereby fully perfected and in full force and effect.

18. PLEDGORS OBLIGATIONS ABSOLUTE, ETC. The obligations of each Pledgor under this Agreement shall be absolute and unconditional and shall remain in full force and effect without regard to, and shall not be
released, suspended, discharged, terminated or otherwise affected by, any circumstance or occurrence whatsoever (other than termination of this Agreement pursuant to Section 20 hereof), including, without limitation:

(i) any renewal, extension, amendment or modification of, or addition or supplement to or deletion from, any Secured Debt Agreement (other
than this Agreement in accordance with its terms), or any other instrument or agreement referred to therein, or any assignment or transfer of any thereof;

(ii) any waiver, consent, extension, indulgence or other action or inaction under or in respect of any such agreement or instrument including, without limitation, this Agreement (other than a waiver, consent or
extension with respect to this Agreement in accordance with its terms);

(iii) any furnishing of any additional security to
the Pledgee or its assignee or any acceptance thereof or any release of any security by the Pledgee or its assignee;

(iv)
any limitation on any partys liability or obligations under any such instrument or agreement or any invalidity or unenforceability, in whole or in part, of any such instrument or agreement or any term thereof; or

(v) any bankruptcy, insolvency, reorganization, composition, adjustment, dissolution, liquidation or other like proceeding relating to any
Pledgor or any Subsidiary of any Pledgor, or any action taken with respect to this Agreement by any trustee or receiver, or by any court, in any such proceeding, whether or not such Pledgor shall have notice or knowledge of any of the foregoing.

19. SALE OF COLLATERAL WITHOUT REGISTRATION. (a) If an Event of Default shall have occurred and be continuing and any Pledgor shall
have received from the Pledgee a written request or requests that such Pledgor cause any registration, qualification or compliance that is required under any federal or state securities law or laws to be effected with respect to all or any part of
the Collateral consisting of Securities, Limited Liability Company Interests or Partnership Interests, such Pledgor as soon as reasonably practicable and at its expense will use its reasonable best efforts to cause such registration to be so
effected (and be kept effective) as would permit or facilitate the sale and distribution of such Collateral consisting of Securities, Limited Liability Company Interests or Partnership Interests, including, without limitation, registration under the
Securities Act as then in effect (or any similar statute then in effect), appropriate qualifications under applicable blue sky or other state securities laws and appropriate compliance with any other governmental requirements; provided, that
the Pledgee shall furnish to such Pledgor such information regarding the Pledgee as such Pledgor may



21



---

reasonably request in writing and as shall be reasonably required in connection with any such registration, qualification or compliance. Each Pledgor will
cause the Pledgee to be kept reasonably advised in writing as to the progress of each such registration, qualification or compliance and as to the completion thereof, will furnish to the Pledgee such number of prospectuses, offering circulars and
other documents incident thereto as the Pledgee from time to time may reasonably request, and will indemnify, to the extent permitted by law, the Pledgee and all other Secured Creditors participating in the distribution of such Collateral consisting
of Securities, Limited Liability Company Interests or Partnership Interests against all claims, losses, damages and liabilities caused by any untrue statement (or alleged untrue statement) of a material fact contained therein (or in any related
registration statement, notification or the like) or by any omission (or alleged omission) to state therein (or in any related registration statement, notification or the like) a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as the same may have been caused by an untrue statement or omission based upon information furnished in writing to such Pledgor by the Pledgee or such other Secured Creditor expressly for use
therein.

(b) If at any time when the Pledgee shall determine to exercise its right to sell all or any part of the Collateral consisting of
Securities, Limited Liability Company Interests or Partnership Interests pursuant to Section 7 hereof, and such Collateral or the part thereof to be sold shall not, for any reason whatsoever, be effectively registered under the Securities Act
as then in effect, the Pledgee may, in its sole and absolute discretion, sell such Collateral or part thereof by private sale in such manner and under such circumstances as the Pledgee may deem necessary or advisable in order that such sale may
legally be effected without such registration. Without limiting the generality of the foregoing, in any such event the Pledgee, in its sole and absolute discretion (i) may proceed to make such private sale notwithstanding that a registration
statement for the purpose of registering such Collateral or part thereof shall have been filed under such Securities Act, (ii) may approach and negotiate with a single possible purchaser to effect such sale, and (iii) may restrict such
sale to a purchaser who will represent and agree that such purchaser is purchasing for its own account, for investment, and not with a view to the distribution or sale of such Collateral or part thereof. In the event of any such sale, the Pledgee
shall incur no responsibility or liability for selling all or any part of the Collateral at a price which the Pledgee, in its sole and absolute discretion, may in good faith deem reasonable under the circumstances, notwithstanding the possibility
that a substantially higher price might be realized if the sale were deferred until the registration as aforesaid.

20. TERMINATION;
RELEASE. (a) On the Termination Date, this Agreement shall terminate (provided that all indemnities set forth herein including, without limitation, in Section 11 hereof shall survive any such termination) and the Pledgee, at the request
and expense of such Pledgor, will execute and deliver to such Pledgor a proper instrument or instruments acknowledging the satisfaction and termination of this Agreement (including, without limitation, UCC-3 termination statements and instruments of
satisfaction, discharge and/or reconveyance), and will duly release from the security interest created hereby and assign, transfer and deliver to such Pledgor (without recourse and without any representation or warranty) such of the Collateral as
may be in the possession of the Pledgee and as has not theretofore been sold or otherwise applied or released pursuant to this Agreement, together with any moneys at the time held by the Pledgee or any of its sub-agents hereunder and, with respect
to any Collateral consisting of an Uncertificated Security, a Partnership Interest or a Limited Liability Company



22



---

Interest (other than an Uncertificated Security, Partnership Interest or Limited Liability Company Interest credited on the books of a Clearing Corporation
or Securities Intermediary), a termination of the agreement relating thereto executed and delivered by the issuer of such Uncertificated Security pursuant to Section 3.2(a)(ii) or by the respective partnership or limited liability company
pursuant to Section 3.2(a)(iv)(2). As used in this Agreement, Termination Date shall mean the date upon which the Commitments under the Credit Agreement have been terminated and all Secured Hedging Agreements entitled to the
benefits of this Agreement have been terminated, no Note (as defined in the Credit Agreement) is outstanding (and all Loans have been repaid in full), all Letters of Credit issued under the Credit Agreement have been terminated, and all other
Obligations (other than indemnities described in Section 11 hereof and described in Section 13.01 of the Credit Agreement, and any other indemnities set forth in any other Security Documents, in each case which are not then due and
payable) then due and payable have been paid in full.

(b) In the event that any part of the Collateral is sold or to be sold or otherwise
disposed of (to a Person other than a Credit Party) (x) at any time prior to the time at which all Credit Document Obligations have been paid in full and all Commitments and Letters of Credit under the Credit Agreement have been terminated, in
connection with a sale or disposition permitted by Section 10.02 of the Credit Agreement or is otherwise released at the direction of the Required Lenders (or all the Lenders if required by Section 13.12 of the Credit Agreement) or
(y) at any time thereafter, to the extent permitted by the other Secured Debt Agreements, and in the case of clauses (x) and (y), the proceeds of such sale or disposition (or from such release) are or will be applied in accordance with the
terms of the Credit Agreement or such other Secured Debt Agreement, as the case may be, to the extent required to be so applied, the Pledgee, at the request and expense of such Pledgor, will duly release from the security interest created hereby
(and will execute and deliver such documentation, including termination or partial release statements and the like in connection therewith) and assign, transfer and deliver to such Pledgor (without recourse and without any representation or
warranty) such of the Collateral as is then being (or has been) so sold or otherwise disposed of, or released, and as may be in the possession of the Pledgee (or, in the case of Collateral held by any sub-agent designated pursuant to Section 4
hereto, such sub-agent) and has not theretofore been released pursuant to this Agreement. Furthermore, upon the release of any Subsidiary Guarantor from the Subsidiaries Guaranty in accordance with the provisions thereof, such Pledgor (and the
Collateral at such time assigned by the respective Pledgor pursuant hereto) shall be released from this Agreement.

(c) At any time that
any Pledgor desires that Collateral be released as provided in the foregoing Section 20(a) or (b), it shall deliver to the Pledgee (and the relevant sub-agent, if any, designated pursuant to Section 4 hereof) a certificate signed by an
authorized officer of such Pledgor stating that the release of the respective Collateral is permitted pursuant to Section 20(a) or (b) hereof.

(d) The Pledgee shall have no liability whatsoever to any other Secured Creditor as the result of any release of Collateral by it in accordance with (or which the Pledgee in good faith believes to be in accordance
with) this Section 20.

32. RELEASE OF PLEDGORS. If at any time all of the Equity Interests of any Pledgor owned by the Borrower
or any other Pledgor are sold (to a Person other than a Credit Party) in a transaction permitted pursuant to the Credit Agreement (and which does not violate the terms of any other Secured Debt Agreement then in effect), then, such Pledgor shall be
released as a Pledgor pursuant to this Agreement without any further action hereunder (it being understood that the sale of all of the Equity Interests in any Person that owns, directly or indirectly, all of the Equity Interests in any Pledgor shall
be deemed to be a sale of all of the Equity Interests in such Pledgor for purposes of this Section), and the Pledgee is authorized and directed to execute and deliver such instruments of release as provided by Section 20(a) of this Agreement.

the release of such Pledgor is permitted pursuant to this Section 32. The Pledgee shall have no liability whatsoever to any other Secured Creditor as a result of the release of any Pledgor by it in accordance with, or which it believes in good
faith to be in accordance with, this Section 32.
