 (g) all Fixtures; 

(h) all General Intangibles (including, without limitation, all rights in and under Swap Agreements); 

(i) all Instruments; 
 (j) all
Intellectual Property; 
 (k) all Inventory; 

(l) all Investment Property; 

(m) all Letter-of-Credit Rights; 

(n) all other Property not otherwise described above (except for the Excluded Collateral and any Property specifically excluded from any
defined term used in any clause of this Section); 
 (o) all books and records pertaining to the Collateral; and 

(p) to the extent not otherwise included, all Proceeds, Supporting Obligations and products of any and all of the foregoing and all collateral
security and guarantees given by any Person with respect to any of the foregoing; 
 provided, however, notwithstanding anything to the contrary
contained herein, “Collateral” shall not include, and this Agreement shall not constitute a grant of a security interest in: (a) any property to the extent that such grant of a security interest is prohibited by any applicable law or
regulation of a Governmental Authority to which such Grantor or its property is subject, or constitutes a breach or default under or results in the termination of or requires any consent not obtained under, any license or contract evidencing or
giving rise to such property, except to the extent that the term in such law, regulation, license or contract providing for such prohibition, breach, default or termination or requiring such consent is ineffective under Section 9-406, 9-407,
9-408 or 9-409 of the UCC (or any successor provision or provisions) of any relevant jurisdiction or any other applicable law (including the United States Bankruptcy Code) or principles of equity; provided, however, that such security interest shall
attach immediately at such time as such prohibition, breach, default or termination is no longer applicable or is waived, and to the extent severable, shall attach immediately to any portion of the Collateral that does not result in such
consequences; (b) any deposit accounts (i) exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of such Grantor’s employees or (ii) exclusively holding deposits made by

Excluded Collateral) (i) all Equity 

  
 -7- 

 
Interests in Subsidiaries of the Company (other than the Equity Interests described in clause (e) to the extent set forth therein) and (ii) the right to any distributions (whether
periodic or in liquidation or dissolution) with respect to any Equity Interests, including, without limitation, limited partnership interests or limited liability company member interests. 

Section 3.02 Transfer of Pledged Securities. Subject to the Intercreditor Agreement, all certificates or instruments representing
or evidencing the Pledged Securities shall be delivered to and held pursuant hereto by the Trustee or a Person designated by the Trustee and shall be in suitable form for transfer by delivery, or shall be accompanied by duly executed instruments of
transfer or assignment in blank, and accompanied by any required transfer tax stamps to effect the pledge of the Pledged Securities to the Trustee. Notwithstanding the preceding sentence, at the Trustee’s discretion, all Pledged Securities must
be delivered or transferred in such manner as to permit the Trustee to be a “protected purchaser” to the extent of its security interest as provided in Section 8.303 of the UCC (if the Trustee otherwise qualifies as a protected
purchaser). During the continuance of an Event of Default, subject to the Intercreditor Agreement, the Trustee shall have the right, at any time in its discretion and without notice, to transfer to or to register in the name of the Trustee or any of
its nominees any or all of the Pledged Securities, subject only to the revocable rights of the relevant Grantor specified in Section 6.03. In addition, during the continuance of an Event of Default, subject to the Intercreditor Agreement, the
Trustee shall have the right at any time to exchange certificates or instruments representing or evidencing Pledged Securities for certificates or instruments of smaller or larger denominations. 

ARTICLE IV 

Representations and Warranties 

To induce the Trustee to enter into the Indenture and to induce the Holders to purchase their respective Notes, the Company and, solely with
respect to itself and as applicable, each other Grantor hereby represents and warrants to the Trustee and each Secured Party that as of the Issue Date: 

Section 4.01 [Reserved.] 

Section 4.02 Title; No Other Liens. Except for the security interest granted to the Trustee for the ratable benefit of the Secured
Parties pursuant to this Agreement and the other Liens permitted to exist on the Collateral by the Indenture, such Grantor owns each item of the Collateral free and clear of any and all Liens or claims of others. No effective financing statement or
other public notice with respect to all or any part of the Collateral is on file or of record in any public office, except such as have been filed in favor of the Trustee, for the ratable benefit of the Secured Parties, pursuant to this Agreement or
as are permitted by the Indenture, and such as shall be terminated substantially contemporaneous with the consummation of the Transactions. For the avoidance of doubt, it is understood and agreed that any Grantor may, as part of its business, grant
licenses to third parties to use Intellectual Property owned or developed by a Grantor. For purposes of this Agreement and the other Note Documents, such licensing activity shall not constitute a “Lien” on such Intellectual Property. Each
of the Trustee and each Holder understands that any such licenses may be exclusive to the applicable licensees, and such exclusivity provisions may limit the ability of the Trustee to utilize, sell, lease or transfer the related Intellectual
Property or otherwise realize value from such Intellectual Property pursuant hereto.

 Section 4.03 Perfected Second Priority Liens. Subject to Liens securing the First
Lien Obligations and other Liens permitted to be senior to the security interests granted hereunder pursuant to the terms of the First Lien Documents, the Intercreditor Agreement and the Indenture, the security interests granted pursuant to this
Agreement (a) upon completion of the filings and other actions specified on Schedule 3 (which, in the case of all filings and other documents referred to on said Schedule, have been delivered to the Trustee in completed and duly executed form)
will constitute valid perfected security interests in all of the Collateral which may be perfected by filing or such other action in favor of the Trustee, for the ratable benefit of the Secured Parties, as collateral security for such Grantor’s
Obligations, enforceable in accordance with the terms hereof against all creditors of such Grantor and any Persons purporting to purchase any Collateral from such Grantor and (b) are prior to all other Liens on the Collateral in existence on
the date hereof except for Liens permitted pursuant to Section 4.08 of the Indenture.

grant of a security interest in the Pledged LLC Interests or the Pledged Partnership Interests, (ii) the perfection of such security interest or (iii) the exercise of remedies in respect of such perfected security interest in the Pledged
LLC Interests or the Pledged Partnership Interests, in each case, as contemplated by this Agreement. Upon the exercise of remedies in respect of the Pledged LLC Interests or the Pledged Partnership Interests as provided for herein and otherwise as

licensor or franchisor. 
 (d) No holding, decision or judgment has been rendered by any Governmental Authority which would limit, cancel or

Grantor’s Obligations, enforceable in accordance with the terms hereof against all creditors of such Grantor and any Persons purporting to purchase such Collateral from such Grantor, which security interest shall be prior to all other Liens on
such Collateral except for liens permitted by the Indenture which have priority over the Liens on such Collateral.

it learns thereof and sue for infringement, misappropriation or dilution, to seek injunctive relief where appropriate and to recover any and all damages for such infringement, misappropriation or dilution.

pertaining to such Investment Property at any meeting of shareholders of the relevant Issuer or Issuers or otherwise and (B) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to
such Investment Property as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all of the Investment Property upon the merger, consolidation, reorganization, recapitalization or
other fundamental change in the corporate or other organizational structure of any Issuer, or upon the exercise by any Grantor or the Trustee of any right, privilege or option pertaining to such Investment Property, and in connection therewith, the
right to deposit and deliver any and all of the Investment Property with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Trustee may determine), all without liability except to
account for property actually received by it, but the Trustee shall have no duty to any Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing. 

(c) Each Grantor hereby authorizes and instructs each Issuer of any Investment Property pledged by such Grantor hereunder to (i) comply
with any instruction received by it from the Trustee in writing that (A) states that an Event of Default has occurred and is continuing and (B) is otherwise in accordance with the terms of this Agreement, without any other or further
instructions from such Grantor, and each Grantor agrees that each Issuer shall be fully protected in so complying, and (ii) unless otherwise expressly permitted hereby, pay any dividends or other payments with respect to the Investment Property
directly to the Trustee.

 Section 6.04 Proceeds to be Turned Over to Trustee. In addition to the rights of the
Trustee and the Secured Parties specified in Section 6.01 with respect to payments of Receivables, subject to the Intercreditor Agreement, if an Event of Default shall occur and be continuing, all Proceeds received by any Grantor consisting of
cash, checks and other near-cash items shall be held by such Grantor in trust for the Trustee and the Holders, segregated from other funds of such Grantor, and shall, forthwith upon receipt by such Grantor, be turned over to the Trustee in the exact
form received by such Grantor (duly indorsed by such Grantor to the Trustee, if required). All such Proceeds received by the Trustee hereunder shall be held by the Trustee in a Collateral Account maintained under its sole dominion and control. All
such Proceeds while held by the Trustee in a Collateral Account (or by such Grantor in trust for the Trustee and the Holders) shall continue to be held as collateral security for all the Obligations and shall not constitute payment thereof until
applied as provided in Section 6.05. 
 Section 6.05 Application of Proceeds. If an Event of Default shall have occurred
and be continuing and subject to the Intercreditor Agreement, the Trustee may apply all or any part of Proceeds constituting Collateral, whether or not held in any Collateral Account, in payment of the Obligations in accordance with
Section 4.01 of the Indenture. 
 Section 6.06 Code and Other Remedies. 

(a) Subject to the Intercreditor Agreement, if an Event of Default shall occur and be continuing, the Trustee, on behalf of the Secured
Parties, may exercise, in addition to all other rights and remedies granted to them in this Agreement, the other Note Documents and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of
a secured party under the UCC or any other applicable law or otherwise available at law or equity. Without limiting the generality of the foregoing, the Trustee, without demand of performance or other demand, presentment, protest, advertisement or
notice of any kind (except any notice required by law referred to below) to or upon any Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect,
receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of
the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of any Secured Party or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem
best, for cash or on credit or for future delivery without assumption of any credit risk. Any Secured Party shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to
purchase the whole or any part of the Collateral so sold, free of any right or equity of 

  
 -18- 

 
redemption in any Grantor, which right or equity is hereby waived and released. Each Grantor further agrees, at the Trustee’s request, to assemble the Collateral and make it available to the
Trustee at places which the Trustee shall reasonably select, whether at such Grantor’s premises or elsewhere. Any such sale or transfer by the Trustee either to itself or to any other Person shall be absolutely free from any claim of right by
any Grantor, including any equity or right of redemption, stay or appraisal which any Grantor has or may have under any rule of law, regulation or statute now existing or hereafter adopted (and each Grantor hereby waives any rights it may have in
respect thereof). Upon any such sale or transfer, the Trustee shall have the right to deliver, assign and transfer to the purchaser or transferee thereof the Collateral so sold or transferred. The Trustee shall apply the net proceeds of any action
taken by it pursuant to this Section 6.06, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the
Collateral or the rights of the Trustee and the Secured Parties hereunder, including, without limitation, reasonable attorneys’ fees and disbursements, to the payment in whole or in part of the Obligations, in accordance with the Indenture, and
only after such application and after the payment by the Trustee of any other amount required by any provision of law, including, without limitation, Section 9.615(a)(3) of the UCC, need the Trustee account for the surplus, if any, to any
Grantor. To the extent permitted by applicable law, each Grantor waives all claims, damages and demands it may acquire against the Trustee or any Secured Party arising out of the exercise by them of any rights hereunder except to the extent caused
by the gross negligence or willful misconduct of the Trustee or such Secured Party or their respective agents. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and
proper if given at least 10 days before such sale or other disposition. 
 (b) In the event that the Trustee elects not to sell the
Collateral, the Trustee retains its rights to dispose of or utilize the Collateral or any part or parts thereof in any manner authorized or permitted by law or in equity, and to apply the proceeds of the same towards payment of the Obligations. Each
and every method of disposition of the Collateral described in this Agreement shall constitute a commercially reasonable method of disposition. Without limitation of the foregoing, any disposition involving three (3) or more bidders that are
“accredited investors” (within the meaning of the Securities Act) shall constitute disposition in a commercially reasonable manner. 

(c) The Trustee may appoint any Person as agent to perform any act or acts necessary or incident to any sale or transfer of the Collateral.

 Section 6.07 Registration Rights. 

(a) Subject to the Intercreditor Agreement, if the Trustee shall determine to exercise its right to sell any or all of the Pledged Securities
pursuant to Section 6.06, and if in the opinion of the Trustee it is necessary or advisable to have the Pledged Securities, or that portion thereof to be sold, registered under the provisions of the Securities Act, the relevant Grantor will use
commercially reasonable efforts to cause the Issuer thereof to (i) execute and deliver, and cause the directors and officers of such Issuer to execute and deliver, all such instruments and documents, and do or cause to be done all such other
acts as may be, in the reasonable opinion of the Trustee, necessary or advisable to register the Pledged Securities, or that portion thereof to be 

  
 -19- 

 
sold, under the provisions of the Securities Act, (ii) use its commercially reasonable efforts to cause the registration statement relating thereto to become effective and to remain
effective for a period of one year from the date of the first public offering of the Pledged Securities, or that portion thereof to be sold and (iii) use its commercially reasonable efforts to cause the Issuer to make all amendments thereto
and/or to the related prospectus which, in the opinion of the Trustee, are necessary or advisable to enable it to realize upon such Collateral, all in conformity with the requirements of the Securities Act and the rules and regulations of the
Securities and Exchange Commission applicable thereto. Each Grantor agrees to use its commercially reasonable efforts to cause such Issuer to comply with the provisions of the securities or “Blue Sky” laws of any and all jurisdictions
which the Trustee shall designate and to make available to its security holders, as soon as practicable, an earnings statement (which need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act. 

(b) Each Grantor recognizes that the Trustee may be unable to effect a public sale of any or all the Pledged Securities, by reason of certain
prohibitions contained in the Securities Act and applicable state securities laws or otherwise, or may determine that a public sale is impracticable or not commercially reasonable, and, accordingly, may resort to one or more private sales thereof to
a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Grantor acknowledges and agrees that
any such private sale may result in prices and other terms less favorable than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable
manner. The Trustee shall be under no obligation to delay a sale of any of the Pledged Securities for the period of time necessary to permit the Issuer thereof to register such securities for public sale under the Securities Act, or under applicable
state securities laws, even if such Issuer would agree to do so. 
 (c) Each Grantor agrees to use its commercially reasonable efforts to do
or cause to be done all such other acts as may be necessary to make such sale or sales of all or any portion of the Pledged Securities pursuant to this Section 6.07 valid and binding and in compliance with any and all other applicable laws,
rules and regulations. Each Grantor further agrees that a breach of any of the covenants contained in this Section 6.07 will cause irreparable injury to the Secured Parties, that the Secured Parties have no adequate remedy at law in respect of
such breach and, as a consequence, that each and every covenant contained in this Section 6.07 shall be specifically enforceable against such Grantor, and, to the maximum extent permitted by applicable law, such Grantor hereby waives and agrees
not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred under the Indenture. 

Section 6.08 Deficiency. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of
the Collateral are insufficient to pay its Obligations and the fees and disbursements of any attorneys employed by the Trustee or any Secured Party to collect such deficiency. 

Section 6.09 Non-Judicial Enforcement. The Trustee may enforce its rights hereunder without prior judicial process or judicial
hearing, and to the extent permitted by law, each Grantor expressly waives any and all legal rights which might otherwise require the Trustee to enforce its rights by judicial process.

 ARTICLE VII 

The Trustee 

Section 7.01 Trustee’s Appointment as Attorney-in-Fact, Etc. 

(a) Each Grantor hereby irrevocably constitutes and appoints the Trustee and any officer or agent thereof, with full power of substitution, as
its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Grantor and in the name of such Grantor or in its own name, for the purpose of carrying out the terms of this Agreement, to take any and
all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the
Trustee the power and right, on behalf of such Grantor, without notice to or assent by such Grantor, to do any or all of the following in each case subject to the Intercreditor Agreement: 

(i) in the name of such Grantor or its own name, or otherwise, take possession of and indorse and collect any checks, drafts, notes,
acceptances or other instruments for the payment of moneys due under any Receivable or Contract or with respect to any other Collateral and file any claim or take any other action or proceeding in any court of law or equity or otherwise deemed
appropriate by the Trustee for the purpose of collecting any and all such moneys due under any Receivable or Contract or with respect to any other Collateral whenever payable; 

(ii) in the case of any Intellectual Property, execute and deliver, and have recorded, any and all agreements, instruments, documents and
papers as the Trustee may request to evidence the Trustee’s and the Secured Parties’ security interest in such Intellectual Property and the goodwill and general intangibles of such Grantor relating thereto or represented thereby; 

(iii) pay or discharge Taxes and Liens levied or placed on or threatened against the Collateral, effect any repairs or any insurance called
for by the terms of this Agreement or any other Note Document and pay all or any part of the premiums therefor and the costs thereof; 

(iv) execute, in connection with any sale provided for in Section 6.06 or Section 6.07, any indorsements, assignments or other
instruments of conveyance or transfer with respect to the Collateral; and 
 (v) (A) direct any party liable for any payment under any of
the Collateral to make payment of any and all moneys due or to become due thereunder directly to the Trustee or as the Trustee shall direct; (B) ask or demand for, collect, and receive payment of and receipt for, any and all moneys,
claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (C) sign and indorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against
debtors, assignments, verifications, notices and other documents in connection with any of the Collateral; (D) in the 

  
 -21- 

 
name of such Grantor, or in its own name, or otherwise, commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the
Collateral or any portion thereof and to enforce any other right in respect of any Collateral; (E) defend any suit, action or proceeding brought against such Grantor with respect to any Collateral; (F) settle, compromise or adjust any such
suit, action or proceeding and, in connection therewith, give such discharges or releases as the Trustee may deem appropriate; (G) assign any Copyright, Patent or Trademark (along with the goodwill of the business to which any such Copyright,
Patent or Trademark pertains), throughout the world for such term or terms, on such conditions, and in such manner, as the Trustee shall in its sole discretion determine; and (H) generally, sell, transfer, pledge and make any agreement with
respect to or otherwise deal with any of the Collateral as fully and completely as though the Trustee were the absolute owner thereof for all purposes, and do, at the Trustee’s option and such Grantor’s expense, at any time, or from time
to time, all acts and things which the Trustee deems necessary to protect, preserve or realize upon the Collateral and the Trustee’s and the Secured Parties’ security interests therein and to effect the intent of this Agreement, all as
fully and effectively as such Grantor might do. 
 Anything in this Section 7.01(a) to the contrary notwithstanding, the Trustee agrees
that it will not exercise any rights under the power of attorney provided for in this Section 7.01(a) unless an Event of Default shall have occurred and be continuing. 

(b) If any Grantor fails to perform or comply with any of its agreements contained herein, the Trustee, at its option, but without any
obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement. 
 (c) The expenses of the
Trustee incurred in connection with actions undertaken as provided in this Section 7.01, together with interest thereon at the rate specified in the Indenture, but in no event to exceed the highest lawful rate, from the date of payment by the
Trustee to the date reimbursed by the relevant Grantor, shall be payable by such Grantor to the Trustee on demand. 
 (d) Each Grantor
hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. All powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated
and the security interests created hereby are released. 
 Section 7.02 Duty of Trustee. The Trustee’s sole duty with
respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9.207 of the UCC or otherwise, shall be to deal with it in the same manner as the Trustee deals with similar Property for its own
account, and the Trustee shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which comparable secured parties
accord comparable collateral. Neither the Trustee, any Secured Party nor any of their Related Parties shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation
to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the Trustee and the Secured Parties
hereunder are solely to protect the Trustee’s and the Secured Parties’ interests in the 

  
 -22- 

 
Collateral and shall not impose any duty upon the Trustee or any Secured Party to exercise any such powers. The Trustee and the Secured Parties shall be accountable only for amounts that they
actually receive as a result of the exercise of such powers, and neither they nor any of their Related Parties shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.
To the fullest extent permitted by applicable law, the Trustee shall be under no duty whatsoever to make or give any presentment, notice of dishonor, protest, demand for performance, notice of non-performance, notice of intent to accelerate, notice
of acceleration, or other notice or demand in connection with any Collateral or the Obligations, or to take any steps necessary to preserve any rights against any Grantor or other Person or ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not it has or is deemed to have knowledge of such matters. Each Grantor, to the extent permitted by applicable law, waives any right of marshaling in
respect of any and all Collateral, and waives any right to require the Trustee or any Secured Party to proceed against any Grantor or other Person, exhaust any Collateral or enforce any other remedy which the Trustee or any Secured Party now has or
may hereafter have against any Grantor or other Person. 
 Section 7.03 Execution of Financing Statements. Pursuant to the UCC
and any other applicable law, each Grantor authorizes the Trustee to file or record financing statements and other filing or recording documents or instruments with respect to the Collateral without the signature of such Grantor in such form and in
such offices as the Trustee determines appropriate to perfect the security interests of the Trustee under this Agreement. A photographic or other reproduction of this Agreement shall be sufficient as a financing statement or other filing or
recording document or instrument for filing or recording in any jurisdiction. Each Grantor authorizes the Trustee to use the collateral description “all personal property” or “all assets” in any such financing statements. Each
Grantor hereby ratifies and authorizes the filing by the Trustee of any financing statement with respect to the Collateral made prior to the date hereof. 

Section 7.04 Authority of Trustee. Each Grantor acknowledges that the rights and responsibilities of the Trustee under this
Agreement with respect to any action taken by the Trustee or the exercise or non-exercise by the Trustee of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall,
as between the Trustee and the Secured Parties, be governed by the Indenture and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Trustee and the Grantors, the Trustee shall be conclusively
presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority. 

ARTICLE VIII 

Subordination of Indebtedness 

Section 8.01 Subordination of All Grantor Claims. As used herein, the term “Grantor Claims” shall mean all debts
and obligations of the Company or any other Grantor to any other Grantor, whether such debts and obligations now exist or are hereafter incurred or arise, or whether the obligation of the debtor thereon be direct, contingent, primary, secondary,
several, joint and several, or otherwise, and irrespective of whether such debts or obligations be 

  
 -23- 

 
evidenced by note, contract, open account, or otherwise, and irrespective of the Person or Persons in whose favor such debts or obligations may, at their inception, have been, or may hereafter be
created, or the manner in which they have been or may hereafter be acquired by. After and during the continuation of an Event of Default, no Grantor shall receive or collect, directly or indirectly, from any obligor in respect thereof any amount
upon the Grantor Claims. 
 Section 8.02 Claims in Bankruptcy. In the event of receivership, bankruptcy, reorganization,
arrangement, debtor’s relief, or other insolvency proceedings involving any Grantor, the Trustee on behalf of the Trustee and the Secured Parties shall have the right to prove their claim in any such proceeding, so as to establish their rights
hereunder and receive directly from the receiver, trustee or other court custodian, dividends and payments which would otherwise be payable upon Grantor Claims. Each Grantor hereby assigns such dividends and payments to the Trustee for the benefit
of the Trustee and the Secured Parties for application against the Obligations as provided under Section 8.01 of the Indenture. Should the Trustee or Secured Party receive, for application upon the Obligations, any such dividend or payment
which is otherwise payable to any Grantor, and which, as between such Grantors, shall constitute a credit upon the Grantor Claims, then upon payment in full in cash of the Obligations, the intended recipient shall become subrogated to the rights of
the Trustee and the Secured Parties to the extent that such payments to the Trustee and the Secured Parties on the Grantor Claims have contributed toward the liquidation of the Obligations, and such subrogation shall be with respect to that
proportion of the Obligations which would have been unpaid if the Trustee and the Secured Parties had not received dividends or payments upon the Grantor Claims. 

Section 8.03 Payments Held in Trust. In the event that, notwithstanding Section 8.01 and Section 8.02, any Grantor
should receive any funds, payments, claims or distributions which is prohibited by such Sections, then it agrees: (a) to hold in trust for the Trustee and the Secured Parties an amount equal to the amount of all funds, payments, claims
or distributions so received and (b) that it shall have absolutely no dominion over the amount of such funds, payments, claims or distributions except to pay them promptly to the Trustee, for the benefit of the Secured Parties; and each
Grantor covenants promptly to pay the same to the Trustee. 
 Section 8.04 Liens Subordinate. Each Grantor agrees that, until
the Obligations are paid in full in cash, any Liens securing payment of the Grantor Claims shall be and remain inferior and subordinate to any Liens securing payment of the Obligations, regardless of whether such encumbrances in favor of such
Grantor, the Trustee or any Secured Party presently exist or are hereafter created or attach. Without the prior written consent of the Trustee, no Grantor, during the period in which any of the Obligations are outstanding, shall
(a) exercise or enforce any creditor’s right it may have against any debtor in respect of the Grantor Claims or (b) foreclose, repossess, sequester or otherwise take steps or institute any action or proceeding (judicial
or otherwise, including without limitation the commencement of or joinder in any liquidation, bankruptcy, rearrangement, debtor’s relief or insolvency proceeding) to enforce any Lien held by it. 

Section 8.05 Notation of Records. Upon the request of the Trustee, all promissory notes and all accounts receivable ledgers or
other evidence of the Grantor Claims accepted by or held by any Grantor shall contain a specific written notice thereon that the indebtedness evidenced thereby is subordinated under the terms of this Agreement.

 ARTICLE IX 

Miscellaneous 

Section 9.01 No Waiver by Course of Conduct; Cumulative Remedies. Neither the Trustee nor any Secured Party shall by any act
(except by a written instrument pursuant to Section 9.04), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default. No failure to exercise, nor any
delay in exercising, on the part of the Trustee or any Secured Party, and no course of dealing with respect to, any right, power or privilege hereunder, or any abandonment or discontinuance of steps to enforce such right, power or privilege, shall
operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Trustee or any Secured
Party of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Trustee or such Secured Party would otherwise have on any future occasion. The rights and remedies herein provided are
cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law or equity. 

Section 9.02 Notices. All notices and other communications provided for herein shall be given in the manner and subject to the
terms of Section 11.03 of the Indenture; provided that any such notice, request or demand to or upon any Guarantor shall be addressed to such Guarantor at its notice address set forth on Schedule 1.

of this Agreement shall be binding upon the Grantors and their successors and assigns and shall inure to the benefit of the Trustee and the Secured Parties and their respective successors and permitted assigns; provided that no Grantor may assign,
transfer or delegate any of its rights or obligations under this Agreement, and any such purported assignment, transfer or delegation shall be null and voice. 

Section 9.06 Survival; Revival; Reinstatement. 

(a) All covenants, agreements, representations and warranties made by any Grantor herein and in the certificates or other instruments
delivered in connection with or pursuant to this Agreement or any other Note Document to which it is a party shall be considered to have been relied upon by the Trustee and the Holders and shall survive the execution and delivery of this Agreement
and the issuing of the Notes, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Trustee or any Secured Party may have had notice or knowledge of any Default or incorrect representation or
warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Note or any fee or any other amount payable under the Indenture is outstanding. The
provisions of Section 9.03 shall survive and remain in full 

  
 -25- 

 
force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Notes or the termination of this Agreement, the Indenture, any other Note Document or
any provision hereof or thereof. 
 (b) To the extent that any payments on the Obligations or proceeds of any Collateral are subsequently
invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Obligations so
satisfied shall be revived and continue as if such payment or proceeds had not been received and the Trustee’s and the Secured Parties’ Liens, security interests, rights, powers and remedies under this Agreement and each other Note
Document shall continue in full force and effect. In such event, each Note Document shall be automatically reinstated and the Company shall take such action as may be reasonably requested by the Trustee and the Secured Parties to effect such
reinstatement. 
 Section 9.07 Counterparts; Integration; Effectiveness. 

(a) This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute
an original, but all of which when taken together shall constitute a single contract. 
 (b) This Agreement, the other Note Documents
and any separate letter agreements with respect to fees payable to the Trustee constitute the entire contract among the parties relating to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral
or written, relating to the subject matter hereof and thereof. THIS AGREEMENT AND THE OTHER NOTE DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND THERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. 
 (c) This Agreement shall
become effective when it shall have been executed by the Trustee and when the Trustee shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon
and inure to the benefit of the parties hereto, the Holders and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or other electronic transmission shall be effective as
delivery of a manually executed counterpart of this Agreement. 
 Section 9.08 Severability. Any provision of this Agreement or
any other Note Document held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and
enforceability of the remaining provisions hereof or thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

 (b) EACH PARTY TO THIS AGREEMENT AND, BY ITS ACCEPTANCE
OF THE NOTES, EACH HOLDER HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT, THE

party; 
 (b) neither the Trustee nor any Secured Party has any fiduciary relationship with or duty to any Grantor arising out of or in

creditor; and

of the Company that is required to become a party to this Agreement pursuant to Article XII of the Indenture shall become a party hereto as a Grantor for all purposes of this Agreement upon execution and delivery by such Subsidiary of an Assumption
Agreement and shall thereafter have the same rights, benefits and obligations as a Grantor party hereto on the date hereof. Each Grantor that is required to pledge additional Equity Interests pursuant to the Indenture shall execute and deliver a
Supplement. 
 Section 9.14 Releases. 

(a) Release Upon Payment in Full. The grant of the security interest hereunder, all other grants of interests, set off and other Liens
hereunder, the security interest granted hereunder, all other interest, set offs and other Liens granted hereunder, and all Lien rights, powers and interests and guarantee benefits with respect thereto shall automatically terminate and be null and
void immediately upon the date that the Obligations (other than Obligations in respect of Indebtedness consisting of payment obligations that are provided under any Note Document as surviving the termination of such Note Document or other
transaction contemplated thereby, or words of similar import) shall have been indefeasibly paid in full in cash, and the Trustee, at the written request and expense of the Company, will promptly take all steps and actions requested by the Company to
evidence and more fully effect the foregoing termination, including the release, reassignment and transfer, without recourse or warranty, of the property theretofore constituting the Collateral to the Grantors and the declaration of all such
guarantees and this Agreement to be of no further force or effect. 
 (b) Partial Releases. If any of the Collateral shall be sold,
transferred or otherwise disposed of by any Grantor in a transaction permitted by the Indenture and the Intercreditor Agreement, then immediately upon the occurrence of any such disposition, all Liens and other rights with respect thereto, shall
automatically terminate and be null and void, and the Trustee, at the request and sole expense of such Grantor, shall promptly execute and deliver to such Grantor all releases or other documents deemed reasonably necessary or desirable by the
Company to evidence the release of the Liens created hereby on such Collateral. If all the Equity Interests of a Grantor shall be sold, transferred or otherwise disposed of in a transaction permitted by the Credit Agreement, then immediately upon
the occurrence of such disposition, such Guarantor automatically shall be released from its obligations hereunder, and the Liens and other rights created hereunder in all property of such Guarantor shall automatically terminate and be null and void;
and at the request and sole expense of the Company, the Trustee shall promptly execute and deliver to or at the request of the Company all releases and other documents reasonable necessary or desirable to release such obligations, Liens and other
rights; provided that the Company shall have delivered to the Trustee, at least fifteen days prior to the date of the requested releases and documents, a written request of an Officer for release identifying the relevant Grantor and the terms of the
sale or other disposition in reasonable detail, including the price thereof and any expenses in connection therewith, together with a certification by the Company stating that such transaction is in compliance with the Credit Agreement and the other
Note Documents. 
 (c) Retention in Satisfaction. Except as may be expressly applicable pursuant to Section 9.620 of the UCC, no
action taken or omission to act by the Trustee or the Secured 

  
 -28- 

 
Parties hereunder, including, without limitation, any exercise of voting or consensual rights or any other action taken or inaction, shall be deemed to constitute a retention of the Collateral in
satisfaction of the Obligations or otherwise to be in full satisfaction of the Obligations, and the Obligations shall remain in full force and effect, until the Trustee and the Secured Parties shall have applied payments (including, without
limitation, collections from Collateral) towards the Obligations in the full amount then outstanding or until such subsequent time as is provided in Section 9.14(a). 

Section 9.15 Acceptance. Each Grantor hereby expressly waives notice of acceptance of this Agreement, acceptance on the part of
the Trustee and the Secured Parties being conclusively presumed by their request for this Agreement and delivery of the same to the Trustee. 

Section 9.16 Intercreditor Agreement. 

(a) Notwithstanding anything herein to the contrary, (i) the Liens and security interests granted to Trustee, in its capacity as trustee
hereunder, for the benefit of the Secured Parties pursuant to this Agreement and (ii) the exercise of any right or remedy by Trustee, in its capacity as trustee hereunder or the application of proceeds (including insurance proceeds and
condemnation proceeds) of any Collateral are subject to the provisions of the Intercreditor Agreement dated as of March 31, 2016 (as amended, restated, supplemented or otherwise modified from time to time, the “Intercreditor
Agreement”), by and among Royal Bank of Canada, in its capacity as the First Lien RBL Agent, Trustee, in its capacity as the Second Lien Agent (as defined therein), each Permitted Additional First Lien Representative (as defined therein), each
Permitted Third Lien Representative (as defined therein), the Company, and the Subsidiaries of the Company named therein. In the event of any conflict between the terms of the Intercreditor Agreement and the terms of this Agreement, the terms of the
Intercreditor Agreement shall govern. 
 (b) Without limiting the generality of the foregoing clause (a) and subject to the provisions
of the Intercreditor Agreement, with respect to the Collateral, any obligation of any Grantor hereunder or under any other Note Document with respect to the delivery or control of any Collateral, the provisions of voting rights, the turning over of
proceeds to the Trustee or the obtaining of any consent of any Person, in each case in connection with any Collateral shall, until the Discharge of First Lien Priority Obligations, be deemed to be satisfied if such Grantor complies with the
requirements of the similar provision of the applicable First Lien Collateral Document, including, for avoidance of doubt, by delivering any possessory Collateral or granting control over any Collateral to the applicable First Lien Agent.
Notwithstanding anything in this Agreement to the contrary, for purposes of any representation in this Agreement, delivery of Collateral to, or the granting of control over Collateral to, the applicable First Lien Agent shall be deemed to include
delivery of Collateral to, or the granting of control over Collateral to, the Trustee. 
 Notwithstanding anything herein to the contrary,
any request, decision or determination made, or documents or other items deemed satisfactory, desirable, necessary, appropriate or advisable, by any First Lien Agent with respect to the equivalent section under the First Lien Collateral Documents
(as defined in the Intercreditor Agreement), shall be deemed to have been made, or deemed satisfactory, desirable, necessary, appropriate or advisable by the Trustee.
