acceptance of any financing statement, continuation statement, or amendment, and each Grantor agrees to furnish any such information to the Collateral Agent promptly upon request. The Collateral Agent shall inform the applicable Grantor of any such
filing either prior to, or reasonably promptly after, such filing. Each Grantor acknowledges that it is not authorized to file any financing statement covering the Collateral or amendment or termination statement with respect to any financing
statement covering the Collateral without the prior written consent of the Collateral Agent and agrees that it will not do so without such consent, subject to (i) the Grantors’ rights under Section 9-509(d)(2) of Article 9 of the UCC
and (ii) financing statements that may be filed, in accordance with the Indenture or each Intercreditor Agreement (if any), to perfect or release any ABL Liens or Permitted Liens. 

(c) Other Perfection, etc. Each Grantor shall, at any time and from time to time (i) notify, in form and substance reasonably
satisfactory to the Collateral Agent, any warehouseman, bailee, or any of such Grantor’s agents or processors having possession of any Collateral consisting of Inventory or Equipment with a Fair Market Value in excess of $2,500,000 (calculated
based on the Grantor’s estimate of the Fair Market Value of the Inventory or Equipment to be possessed by such warehouseman, bailee, agent or processor over the course of any calendar year on a weighted average basis) of the security interest
of the Collateral Agent in such Collateral (with a copy of such notice sent to the Collateral Agent), (ii) use its commercially reasonable efforts to obtain an acknowledgment, in form and substance reasonably satisfactory to the Collateral
Agent, from such warehouseman, bailee, agent or processor (other than with respect to any ABL First Lien Collateral, unless the ABL Collateral Agent, if any, shall also have obtained such acknowledgement from such warehouseman, bailee, agent or
processor) and not having otherwise entered into a subordination agreement for the benefit of the Collateral Agent, stating that the warehouseman, bailee, agent or processor holds such Collateral for the Collateral Agent, subject to each
Intercreditor Agreement (if any) and (iii) take such steps as are necessary or as the Collateral Agent may reasonably request (A) for the Collateral Agent to obtain “control” of any Investment Property Collateral, deposit
accounts, letter-of-credit rights, or Electronic Chattel Paper (as such terms, to the extent they are undefined herein, are defined by Article 9 of the UCC with corresponding provisions thereof defining what constitutes “control” for
such items of Collateral) constituting Noteholder First Lien Collateral in excess of $500,000 (other than Investment Property Collateral constituting Equity Interests of a Subsidiary for which no minimum dollar amount shall apply), excluding any
Excluded Assets, with any agreements establishing control to be in form and substance reasonably satisfactory to the Collateral Agent and (B) to otherwise ensure the continued perfection and priority of the Collateral Agent’s security
interest in any of the Collateral (to the extent required hereunder) and of the preservation of its rights therein. The $500,000 threshold described in clause (iii)(A) of the preceding sentence as it relates to any deposit account shall be measured
by reference to the closing balance of such deposit account as of each Business Day. 
 (d) Change of Name, Etc. Each Grantor agrees

(iii) such Grantor’s Federal Taxpayer Identification Number or organizational identification number assigned to it by its jurisdiction of incorporation or formation; or (iv) the acquisition by


  
 14 








 
such Grantor of any material property for which additional filings or recordings are necessary to perfect and maintain the Collateral Agent’s security interest therein (to the extent
perfection of the security interest in such property is required hereby or by the terms of the Indenture). Each Grantor agrees not to effect or permit any change referred to in the preceding sentence unless all filings are promptly made under the
Uniform Commercial Code or other applicable law that are required in order for the Collateral Agent to continue at all times following such change to have a valid, legal and perfected, security interest (subject to the terms of each Intercreditor
Agreement (if any) and subject to Permitted Liens) in the Collateral for its benefit and the benefit of the other Secured Parties. 
 (e)
Change in Location of Collateral. No Grantor shall (i) maintain any Collateral with a Fair Market Value in excess of $2,500,000 (other than Inventory in transit, consignments of Inventory not in excess of $2,500,000, rolling stock,
equipment in transit between locations set forth in Exhibit A, equipment at other locations for purposes of maintenance or repair and Collateral in the Collateral Agent’s possession or the possession of any ABL Collateral Agent) at any
location other than those locations listed on Exhibit A, (ii) otherwise change or add to any of such locations, or (iii) change the location of its jurisdiction of organization from the location identified in
Exhibit A, unless in each case it gives the Collateral Agent prompt written notice thereof but in any event described in clause (iii) not later than 30 days prior thereto, and executes or authorizes the filing of any and all
financing statements and other documents that are necessary or that the Collateral Agent reasonably requests in connection therewith. In the event any Grantor changes or adds any location of Collateral, such Grantor shall prepare and promptly
deliver to the Collateral Agent a revised Exhibit A, which shall automatically be adopted as Exhibit A for all purposes. Each Grantor agrees not to effect or permit any change referred to in the preceding sentences unless all
filings are promptly made under the Uniform Commercial Code or other applicable law that are required in order for the Collateral Agent to continue at all times following such change to have a valid, legal and perfected security interest (subject to
the terms of each Intercreditor Agreement (if any) and subject to Permitted Liens) in the Collateral for its benefit and the benefit of the other Secured Parties. 

Section 4.2 Perfection and Protection of Security Interest. 

(a) Perfection and Protection. Each Grantor shall, at its expense, perform all steps necessary or otherwise reasonably requested by the
Collateral Agent (at the direction of the Majority Holders) at any time to perfect, maintain, protect, and enforce the Collateral Agent’s Liens, subject to the terms of each Intercreditor Agreement (if any), including: (i) filing and
recording of the Copyright, Patent, and Trademark Agreements, and amendments thereof in the United States Patent and Trademark Office, the United States Copyright Office and the European Patent Office, and filing financing statements or continuation
statements in the respective Filing Office; (ii) to the extent constituting Noteholder First Lien Collateral, delivering to the Collateral Agent the originals of all instruments, documents, and Chattel Paper (in each case in excess of
$250,000), and all other Collateral of which the Collateral Agent is required to have or reasonably requests to have physical possession of in order to perfect and protect the Collateral Agent’s security interest therein, duly pledged,
endorsed, or assigned to the Collateral Agent as provided herein; (iii) deliver to the Collateral Agent a duly executed amendment to this Agreement, in the form of Exhibit F hereto (each, an “Amendment”), pursuant
to which such 

  
 15 








 
Grantor will pledge any additional Collateral that constitutes Commercial Tort Claims; (iv) upon the occurrence and during the continuation of an Event of Default, delivering to the
Collateral Agent (A) warehouse receipts covering any portion of the Noteholder First Lien Collateral located in warehouses and for which warehouse receipts are issued, (B) warehouse receipts covering any portion of the ABL First Lien
Collateral (so long as no Senior Liens are outstanding on such Collateral) located in warehouses and for which warehouse receipts are issued and (C) if requested by the Collateral Agent, certificates of title reflecting the Collateral
Agent’s Liens covering any portion of the Collateral for which certificates of title have been issued; (v) when an Event of Default exists, transferring Inventory to warehouses or other locations designated by the Collateral Agent;
(vi) upon the occurrence and during the continuance of an Event of Default, delivering to the Collateral Agent all letters of credit constituting Collateral on which such Grantor is named beneficiary; and (vii) taking such other steps as
are reasonably deemed necessary or desirable by the Collateral Agent (acting at the direction of the Majority Holders) to maintain, protect and enforce the Collateral Agent’s Liens. To the extent permitted by any Requirement of Law and each
Intercreditor Agreement (if any), the Collateral Agent may file, without any Grantor’s signature, one or more financing statements disclosing the Collateral Agent’s Liens. Each Grantor hereby authorizes the Collateral Agent to attach each
Amendment to this Agreement and agrees that all additional collateral set forth in such Amendments shall be considered to be part of the Collateral. 

(b) Collateral in Other’s Possession. If at any time any Collateral with a Fair Market Value in excess of $2,500,000 (other than
ABL First Lien Collateral, unless (i) no Senior Liens on such Collateral are outstanding or (ii) the applicable ABL Collateral Agent shall also have obtained such waiver or subordination from such landlord) is located at any operating
facility of a Grantor which is not owned by such Grantor, such Grantor shall, upon request, use commercially reasonable efforts to obtain written landlord lien waivers or subordinations, in form and substance reasonably satisfactory to the
Collateral Agent, of all present and future Liens to which the owner or lessor of such premises may be entitled to assert against such Collateral. 

(c) Confirmatory Instruments. From time to time, subject to each Intercreditor Agreement (if any), each Grantor shall, upon the
Collateral Agent’s request, execute and deliver confirmatory written instruments pledging to the Collateral Agent, for the benefit of the Secured Parties, the Collateral with respect to such Grantor, but the failure to do so shall not affect or
limit any security interest or any other rights of the Secured Parties in and to the Collateral with respect to such Grantor. 

Section 4.3 Electronic Chattel Paper. If any Grantor at any time holds or acquires an interest in any Electronic Chattel Paper or
any “transferable record”, as that term is defined in Section 201 of the Federal Electronic Signatures in Global and National Commerce Act, or in Section 16 of the Uniform Electronic Transactions Act as in effect in any relevant
jurisdiction, such Grantor shall promptly notify the Collateral Agent thereof and (other than if such Electronic Chattel Paper constitutes ABL First Lien Collateral for which Senior Liens are outstanding) shall take such action as is necessary to
vest in the Collateral Agent Control under UCC Section 9-105 of such Electronic Chattel Paper or control (to the extent the meaning of “control” has not been clearly established under such provisions, “control” in this
paragraph (d) to have such meaning as the Collateral Agent shall reasonably specify in writing after 

  
 16 








 
consultation with the Issuer) under Section 201 of the Federal Electronic Signatures in Global and National Commerce Act or, as the case may be, Section 16 of the Uniform Electronic
Transactions Act, as so in effect in such jurisdiction, of such transferable record. The Collateral Agent agrees with such Grantor that the Collateral Agent will arrange, pursuant to procedures reasonably satisfactory to the Collateral Agent and so
long as such procedures will not result in the Collateral Agent’s loss of Control or control, as applicable, which may be established to the satisfaction of the Collateral Agent pursuant to the delivery to it by the Grantor of an Officers’
Certificate or an Opinion of Counsel, for the Grantor to make alterations to the Electronic Chattel Paper or transferable record permitted under UCC Section 9-105 or, as the case may be, Section 201 of the Federal Electronic Signatures in
Global and National Commerce Act or Section 16 of the Uniform Electronic Transactions Act for a party in Control to allow without loss of Control or control, as applicable, unless an Event of Default has occurred and is continuing or would
occur after taking into account any action by such Grantor with respect to such Electronic Chattel Paper or transferable record. 

Section 4.4 Maintenance of Property. Except as otherwise permitted hereunder or pursuant to the Indenture Documents, each Grantor
shall maintain all of its property necessary and useful in the conduct of its business, in reasonable operating condition and repair, ordinary wear and tear excepted. 

Section 4.5 Investment Property. 

(a) Registration in Nominee Name; Denominations. The Collateral Agent, on behalf of the Secured Parties, shall hold certificated
Investment Property Collateral in the name of the applicable Grantor, endorsed or assigned in blank or in favor of the Collateral Agent, but following the occurrence and during the continuance of an Event of Default shall have the right (in its sole
and absolute discretion) to hold such Investment Property Collateral in its own name as pledgee, or in the name of its nominee (as pledgee or as sub-agent). Each Grantor will promptly give to the Collateral Agent copies of any material notices or
other material communications received by it with respect to any Investment Property Collateral registered in the name of such Grantor (provided, that if such Investment Property Collateral constitutes ABL First Lien Collateral only so long as no
Senior Liens are outstanding on such Collateral). Following the occurrence and during the continuance of an Event of Default, the Collateral Agent shall at all times have the right to exchange the certificates representing Investment Property
Collateral for certificates of smaller or larger denominations for any purpose consistent with this Agreement (provided, that if such Investment Property Collateral constitutes ABL First Lien Collateral only so long as no Senior Liens are
outstanding on such Collateral). 
 (b) Voting Rights, Distributions, Etc. in Respect of Investment Property Collateral. 

(i) Unless an Event of Default exists and subject to each Intercreditor Agreement (if any), (A) each Grantor shall be
entitled to exercise any and all voting and other consensual rights (including, the right to give consents, waivers, and notifications in respect of any securities) pertaining to its Investment Property Collateral or any part thereof;
provided, however, that without the prior written consent of the Collateral Agent and the Trustee obtained in accordance with the Indenture (provided, that if such 

  
 17 








 
Investment Property Collateral constitutes ABL First Lien Collateral only so long as no Senior Liens are outstanding on such Collateral), no vote shall be cast or consent, waiver, or ratification
given or action taken which would amend, modify, or waive any term, provision, or condition of the certificate of incorporation, bylaws, certificate of formation, or other charter document or other agreement relating to, evidencing or providing for
the issuance of any such Investment Property Collateral, in any manner that would materially impair such Investment Property Collateral, the transferability thereof, or the Collateral Agent’s Liens therein, and (B) each Grantor shall be
entitled to receive and retain any and all dividends, interest paid and other cash distributions in respect of any of such Investment Property Collateral (unless otherwise required by the Indenture). 

(ii) During the existence of an Event of Default, subject to each Intercreditor Agreement (if any) and the rights of any
applicable ABL Collateral Agent and any ABL Secured Parties thereunder, (A) the Collateral Agent may, after delivery of notice to the applicable Grantor, exercise all voting and corporate rights at any meeting of any corporation, partnership,
or other business entity issuing any of the Investment Property Collateral and the proceeds thereof (in cash or otherwise) held by the Collateral Agent hereunder, and any and all rights of conversion, exchange, subscription, or any other rights,
privileges, or options pertaining to any of the Investment Property Collateral as if it were the absolute owner thereof, including, the right to exchange at its discretion any and all of the Investment Property Collateral upon the merger,
consolidation, reorganization, recapitalization, or other readjustment of any Investment Property Issuer or upon the exercise by any such issuer or the Collateral Agent of any right, privilege, or option pertaining to any of the Investment Property
Collateral, and in connection therewith, to deposit and deliver any and all of the Investment Property Collateral with any committee, depositary, transfer agent, registrar, or other designated agency upon such terms and conditions as it may
determine, all without liability except to account for property actually received by it, but the Collateral Agent shall have no duty to exercise any of the aforesaid rights, privileges, or options, and the Collateral Agent shall not be responsible
for any failure to do so or delay in so doing, (B) all rights of any Grantor to exercise the voting and other consensual rights which it would otherwise be entitled to exercise pursuant to Section 4.5(b)(i) and to receive the dividends,
interest, and other distributions which it would otherwise be authorized to receive and retain thereunder shall be suspended until such Event of Default shall no longer exist or as the Collateral Agent shall otherwise specify, and all such rights
shall, until such Event of Default shall no longer exist or as the Collateral Agent shall otherwise specify, thereupon become vested in the Collateral Agent which shall thereupon have the sole right, but no duty, to exercise such voting and other
consensual rights and to receive and hold as Investment Property Collateral such dividends, interest, and other distributions, (C) all dividends, interest, and other distributions which are received by any Grantor contrary to the provisions of
this Section 4.5(b)(ii) shall be received in trust for the benefit of the Collateral Agent, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Collateral Agent as Collateral in the same form as so
received (with any necessary endorsement), and (D) each Grantor shall execute and deliver (or cause to be executed and delivered) to the Collateral Agent all such proxies and other instruments as the Collateral Agent may reasonably request for
the purpose of enabling the Collateral Agent to exercise the voting and other rights which it is entitled to exercise 

  
 18 








 
pursuant to this Section 4.5(b)(ii) and to receive the dividends, interest, and other distributions which it is entitled to receive and retain pursuant to this Section 4.5(b)(ii). The
foregoing shall not in any way limit the Collateral Agent’s power and authority granted pursuant to Section 7.4. After all Events of Default have been cured or waived and the applicable Grantor shall have delivered to the Collateral Agent
certificates to that effect, the Collateral Agent shall, promptly after all such Events of Default have been cured or waived, repay to each Grantor (without interest) all dividends or other distributions that such Grantor would otherwise be
permitted to retain pursuant to the terms of Section 4.5(b)(i) above and that remain in such account. 
 (c) The Grantors will cause or
permit the Collateral Agent from time to time to cause the appropriate Investment Property Issuers (and, if held with a securities intermediary, such securities intermediary) of uncertificated securities or other types of Investment Property
Collateral not represented by certificates to mark their books and records with the numbers and face amounts of all such uncertificated securities or other types of Investment Property Collateral not represented by certificates and all rollovers and
replacements therefor to reflect the Lien of the Collateral Agent granted pursuant to this Agreement. The Grantors will take any actions reasonably necessary to cause (a) the Investment Property Issuers of uncertificated securities which are
Investment Property Collateral, and (b) any securities intermediary which is the holder of any Investment Property Collateral, to cause the Collateral Agent to have and retain Control over such Investment Property Collateral. 

Section 4.6 Proprietary Rights. 

(a) The Issuer, either directly or through any agent, employee, licensee or designee, shall inform the Collateral Agent on an annual basis of
each application for the registration of any material Proprietary Right owned or licensed by the Issuer or any of its Affiliates with the United States Patent and Trademark Office, the United States Copyright Office or any similar office or agency
filed during the preceding year. 
 Section 4.7 Inventory. Each Grantor shall keep its Inventory (other than returned or
obsolete Inventory) in good and marketable condition, except for damaged or defective goods arising in the ordinary course of such Grantor’s business. 

Section 4.8 Commercial Tort Claims. If any Grantor shall at any time, acquire a Commercial Tort Claim, the recovery from which
could reasonably be expected to exceed $500,000, such Grantor shall promptly notify the Collateral Agent thereof in a writing, therein providing a reasonable description and summary thereof, and upon delivery thereof to the Collateral Agent,
together with an Amendment as contemplated by Section 4.2(a)(iii), such Grantor shall be deemed thereby to grant to the Collateral Agent a security interest in such Commercial Tort Claim (subject to each Intercreditor Agreement (if any)). 

Section 4.9 No Interference. Each Grantor agrees that it will not interfere with any right, power and remedy of the Collateral
Agent provided for in this Agreement or now or hereafter existing at law or in equity or by statute or otherwise, or the exercise or beginning of the exercise by the Collateral Agent of any one or more of such rights, powers or remedies.

 Section 4.10 Insurance. 

(a) The Grantors shall maintain with financially sound and reputable insurers insurance that is reasonably consistent with prudent industry
practice. 
 (b) For each of the insurance policies issued as required by this Section 4.10 with respect to Collateral, each Grantor
shall cause the Collateral Agent, for the benefit of the Secured Parties, to be named as an additional insured with respect to insurance policies for general liability for bodily injury and a lenders loss payee for insurance policies for property
damage. Certificates of insurance of the policies shall be delivered to the Collateral Agent if requested. 
 (c) The Issuer shall promptly
provide written notice to the Collateral Agent of any loss, damage, or destruction to the Collateral in excess of (A) $1,500,000 if covered by insurance or (B) $500,000 if not covered by insurance. During the existence of an Event of
Default, subject to each Intercreditor Agreement (if any) and the rights of any applicable ABL Collateral Agent and any ABL Secured Parties thereunder, the Collateral Agent is hereby authorized to directly collect all insurance proceeds in respect
of Collateral and to apply such proceeds in accordance with Section 5.3. 
 (d) Unless the Grantors provide the Collateral Agent with
evidence of the insurance coverage on the Collateral required by this Section 4.10, subject to each Intercreditor Agreement (if any), the Collateral Agent may, upon sixty (60) days’ prior notice, purchase insurance at the applicable
Grantor’s expense to protect the Collateral Agent’s Lien on such Collateral owned by the applicable Grantor. This insurance may, but need not, protect the interests of the Grantors. The coverage that the Collateral Agent purchases may (but
shall not be required to) pay any claim that the Grantors make or any claim that is made against the Grantors in connection with said Collateral. The Grantors may later cancel any insurance purchased by the Collateral Agent but only after providing
the Collateral Agent with evidence that the Grantors have obtained insurance as required by this Agreement. If the Collateral Agent purchases such insurance, the applicable Grantor will be responsible for the costs of that insurance, including
interest and any other reasonable charges the Collateral Agent may impose in connection with the placement of insurance, until the effective date of the cancellation or expiration of the insurance. The costs of the insurance shall be added to the
Obligations. The costs of the insurance may be more than the cost of insurance that the Grantors may be able to obtain on their own. 

Section 4.11 Condemnation. Subject to each Intercreditor Agreement (if any) and the rights of any applicable ABL Collateral Agent
and any ABL Secured Parties thereunder, each Grantor shall, promptly upon learning of the institution of any proceeding for the condemnation or other taking of any of its property with a Fair Market Value in excess of $500,000, notify the Collateral
Agent of the pendency of such proceeding. 
 Section 4.12 Further Assurances. The Grantors shall, at their own cost and expense,
execute and deliver, or cause to be executed and delivered, to the Collateral Agent and/or the Trustee such documents and agreements, and shall take or cause to be taken such actions, as are necessary or that the Collateral Agent and/or the Trustee
may, from time to time, 

  
 20 








 
reasonably request to carry out the terms and conditions of this Agreement and the other Indenture Documents. Upon the acquisition by any Grantor of any After-Acquired Property (but subject to
the limitations, if applicable, set forth herein, in the Indenture or in each Intercreditor Agreement (if any)), such Grantor shall execute and deliver such security instruments, financing statements and certificates and opinions of counsel as shall
be reasonably necessary to vest in the Collateral Agent a perfected security interest or other Lien in such After-Acquired Property and to have such After-Acquired Property added to the Collateral and shall promptly deliver such Officers’
Certificates and Opinions of Counsel as are customary in secured financing transactions in the relevant jurisdiction(s) or as are reasonably requested by the Trustee or the Collateral Agent (subject to customary assumptions, exceptions and
qualifications), and thereupon all provisions of this Agreement relating to the Collateral, shall be deemed to relate to such After-Acquired Property to the same extent and with the same force and effect. If any property or assets of the Issuer or
any Grantor originally deemed to be an Excluded Asset at any point ceases to be an Excluded Asset pursuant to such defined term, all or the applicable portion of such property and assets shall be deemed to be After-Acquired Property and shall be
added to the Notes Collateral in accordance with the Indenture and this Agreement and each Intercreditor Agreement (if any). Subject to each Intercreditor Agreement (if any), such security interests and Liens will be created under security
agreements and other instruments and documents in form reasonably satisfactory to the Collateral Agent, and the Grantors shall deliver or cause to be delivered to the Collateral Agent and the Trustee all such instruments and documents (including
legal opinions, Officers’ Certificates, title insurance policies and lien searches) as are necessary or that the Collateral Agent shall reasonably request to evidence compliance with this Section 4.12. The Grantors shall furnish to the
Collateral Agent each year at the time of delivery of the annual report required to be delivered by the Company pursuant to Section 4.02(a) of the Indenture, an Officer’s Certificate setting forth the information required pursuant to the
Perfection Certificate or confirming that there has been no change in such information since the Effective Date or the date of the most recent certificate delivered pursuant to this Section 4.12. 

ARTICLE V 
 REMEDIES

 Section 5.1 Remedies. 

(a) If an Event of Default has occurred and is continuing: 

(i) the Collateral Agent shall have, for the benefit of the Secured Parties, in addition to all other rights of the Collateral
Agent and the Trustee, the rights and remedies of a secured party under the UCC (whether or not the UCC applies to the affected Collateral) or under any other applicable law when a debtor is in default under a security agreement; 

(ii) the Collateral Agent may, at any time, take possession of the Collateral and keep it on any Grantor’s premises, at
no cost to the Collateral Agent, the Trustee or any other Secured Party or remove any part of it to such other place or places as the Collateral Agent may desire, or any Grantor shall, upon the Collateral Agent’s demand, at such Grantor’s
cost, assemble the Collateral and make it available to the Collateral Agent at a place reasonably convenient to the Collateral Agent; 

  
 21 








 (iii) the Collateral Agent may sell and deliver any Collateral at public or
private sales, for cash, upon credit, or otherwise, at such prices and upon such terms as the Collateral Agent deems advisable, in its sole discretion, and may, if the Collateral Agent deems it reasonable, postpone or adjourn any sale of the
Collateral by an announcement at the time and place of sale or of such postponed or adjourned sale without giving a new notice of sale; provided, that in connection with any such sale of Collateral, the Collateral Agent shall use its reasonable
commercial efforts to maintain the confidentiality of any proprietary information of the Grantors (consistent with the confidentiality obligations of the Holders of the Securities as required by the Indenture Documents). 

(iv) the Collateral Agent may give notice of sole control or any other instruction under any Account Control Agreement and
take any action provided therein with respect to the applicable Collateral; 
 (v) the Collateral Agent may, concurrently
with or following written notice to the Grantors, transfer and register in its name or in the name of its nominee the whole or any part of the Investment Property Collateral, exchange certificates or instruments representing or evidencing Investment
Property Collateral for certificates or instruments of smaller or larger denominations, exercise the voting and all other rights as a holder with respect thereto, collect and receive all cash dividends, interest, principal and other distributions
made thereon and otherwise act with respect to the Investment Property Collateral as though the Collateral Agent was the outright owner thereof. 

(b) Without in any way requiring notice to be given in the following manner, each Grantor agrees that any notice by the Collateral Agent of
sale, disposition, or other intended action hereunder or in connection herewith, whether required by the UCC or otherwise, shall constitute reasonable notice to the Grantors if such notice is mailed by registered or certified mail, return receipt
requested, postage prepaid, or is delivered personally against receipt, at least ten (10) Business Days prior to such action to the Grantors’ address specified in or pursuant to Section 8.1. 

(c) If any Collateral is sold on terms other than payment in full at the time of sale, no credit shall be given against the Obligations until
the Collateral Agent receives payment, and if the buyer defaults in payment, the Collateral Agent may resell the Collateral without further notice to any Grantor. 

(d) In the event the Collateral Agent seeks to take possession of all or any portion of the Collateral by judicial process, each Grantor
irrevocably waives: (i) the posting of any bond, surety, or security with respect thereto which might otherwise be required; (ii) any demand for possession prior to the commencement of any suit or action to recover the Collateral; and
(iii) any requirement that the Collateral Agent retain possession and not dispose of any Collateral until after trial or final judgment. 

  
 22 








 (e) If an Event of Default occurs and is continuing, each Grantor hereby waives all rights to a
hearing prior to the exercise by the Collateral Agent of the Collateral Agent’s rights to repossess the Collateral without judicial process or to replevy, attach, or levy upon the Collateral. 

(f) Each Grantor acknowledges and agrees that the Collateral Agent has no obligation to preserve rights to the Collateral or marshal any
Collateral for the benefit of any Person. 
 (g) Each Grantor acknowledges and agrees that the compliance by the Collateral Agent, on behalf
of the Secured Parties, with any applicable state or federal law requirements may be required in connection with a disposition of the Collateral and such compliance will not be considered to adversely affect the commercial reasonableness of any sale
of the Collateral. 
 (h) The Collateral Agent shall have the right upon any public sale or sales and, to the extent permitted by law, upon
any private sale or sales, to purchase for the benefit of the Collateral Agent and the other Secured Parties, the whole or any part of the Collateral so sold, free of any right of equity redemption, which equity redemption each Grantor hereby
expressly releases. 
 (i) Until the Collateral Agent is able to effect a sale, lease, transfer or other disposition of Collateral, the
Collateral Agent shall have the right, but no duty or obligation, to hold or use Collateral, or any part thereof, to the extent that it deems appropriate for the purpose of preserving Collateral or the value of the Collateral, or for any other
purpose deemed appropriate by the Collateral Agent. The Collateral Agent may, if it so elects, but shall have no obligation to, seek the appointment of a receiver or keeper to take possession of Collateral and to enforce any of the Collateral
Agent’s remedies (for the benefit of the Collateral Agent and Secured Parties), with respect to such appointment without prior notice or hearing as to such appointment. 

(j) Each Grantor recognizes that the Collateral Agent may be unable to effect a public sale of any or all of the Collateral consisting of
securities to be sold by reason of certain prohibitions contained in the laws of any jurisdiction outside the United States or in applicable federal or state securities laws but may be compelled to resort to one or more private sales thereof to a
restricted group of purchasers who will be obliged to agree, among other things, to acquire such Collateral or other property to be sold 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 to the seller than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall not, by virtue
thereof, be deemed to have been made in a commercially unreasonable manner. Unless required by a Requirement of Law, the Collateral Agent shall not be under any obligation to delay a sale of any of the Collateral or other property to be sold for the
period of time necessary to permit the issuer of such securities to register such securities under the laws of any jurisdiction outside the United States or under any applicable federal or state securities laws, even if such issuer would agree to do
so. Each Grantor further agrees to do or cause to be done, at its own cost and expense, to the extent that such Grantor may do so under Requirements of Law, all such other acts and things as may be necessary to make such sales or resales of any
portion or all of the Collateral or other property to be sold valid and binding and in compliance with any and all Requirements of Law at the Grantors’ expense. 

  
 23 








 (k) Any remedy or enforcement action to be taken hereunder by the Collateral Agent with respect
to the Collateral shall be at the written direction of the Majority Holders. 
 (l) Notwithstanding the foregoing, any rights and remedies
provided in this Section 5.1 shall be subject to each Intercreditor Agreement (if any). 
 Section 5.2 Grant of Intellectual
Property License. Effective only upon the occurrence and during the continuance of an Event of Default, for the purpose of enabling the Collateral Agent to exercise the rights and remedies under this Article V at such time as the Collateral
Agent shall be lawfully entitled to exercise such rights and remedies, subject to the terms of each Intercreditor Agreement (if any), each Grantor hereby grants to the Collateral Agent a non-exclusive license or other right to use, without charge,
each Grantor’s labels, patents, copyrights, name, trade secrets, trade names, trademarks, and advertising matter, or any similar property, to the extent constituting Collateral in completing production of, advertising or selling any Collateral,
and, subject to the rights of any licensor or franchisor under such agreements and to the extent not in violation of such agreements, each Grantor’s rights under all licenses and all franchise agreements shall inure to the Collateral
Agent’s benefit for such purpose. 
 Section 5.3 Application of Proceeds. Subject to each Intercreditor Agreement (if any),
the Collateral Agent shall apply the proceeds of any collection, sale, foreclosure or other realization upon any Collateral, as well as any Collateral consisting of cash, as follows: 

FIRST, to the payment of all reasonable costs and expenses incurred by the Collateral Agent (in its capacity as such hereunder or under the

 CONCERNING
THE COLLATERAL AGENT 
 Section 6.1 Reliance by Collateral Agent; Indemnity Against Liabilities, etc. 

(a) Whenever in the performance of its duties under this Agreement or any other Indenture Document, the Collateral Agent shall deem it
necessary or desirable that a matter be proved or established with respect to the Grantors or any other Person in connection with the taking, suffering or omitting of any action hereunder by the Collateral Agent, such matter may be conclusively
deemed to be proved or established by a certificate executed by an Officer of such Person, including an Officers’ Certificate or an Opinion of Counsel, and the Collateral Agent shall have no liability with respect to any action taken, suffered
or omitted in reliance thereon. The Collateral Agent may at any time solicit written confirmatory instructions, including a direction of the Trustee, any Grantor or an order of a court of competent jurisdiction as to any action that it may be
requested or required to take or that it may propose to take in the performance of any of its obligations under this Agreement or any other Indenture Document and shall be fully justified in failing or refusing to act hereunder or under any
Indenture Document until it shall have received such requisite instruction. 
 (b) The Collateral Agent shall be fully protected in relying
upon any note, writing, affidavit, electronic communication, fax, resolution, statement, certificate, instrument, opinion, report, notice (including any notice of an Event of Default or of the cure or waiver thereof), request, consent, order or
other paper or document or oral conversation (including, telephone conversations) which it in good faith believes to be genuine and correct and to have been signed, presented or made by the proper party. The Collateral Agent may conclusively rely,
as to the truth of the statements and the correctness of the opinions expressed therein, upon any notice, certificate or opinion furnished to the Collateral Agent in connection with this Agreement or any other Indenture Document and upon advice and
statements of legal counsel (including counsel to the Issuer or any Grantor, independent accountants and other agents consulted by the Collateral Agent). 

Section 6.2 Exercise of Remedies. The remedies of the Collateral Agent hereunder and under the other Security Documents shall
include, but not be limited to, the disposition of the Collateral by foreclosure or other sale and the exercising of all remedies of a secured lender under the UCC, bankruptcy laws or similar laws of any applicable jurisdiction. 

  
 25 








 Section 6.3 Authorized Investments. Any and all funds held by the Collateral Agent in
its capacity as Collateral Agent, whether pursuant to any provision hereof or of any other Security Document or otherwise, shall, to the extent reasonably practicable following receipt by the Collateral Agent from the Issuer of specific written
instructions in form and substance reasonably satisfactory to the Collateral Agent delivered to the Collateral Agent at least three (3) business days prior to the proposed investment, be invested by the Collateral Agent within a reasonable time
in the Cash Equivalents identified in such written instructions. Any interest earned on such funds shall be disbursed (i) during an Event of Default, in accordance with Section 5.3 and (ii) at all other times, as the Issuer shall
direct. To the extent that the interest rate payable with respect to any such account varies over time, the Collateral Agent may use an average interest rate in making the interest allocations among the respective Secured Parties. In the absence of
gross negligence or willful misconduct, the Collateral Agent shall not be responsible for any investment losses in respect of any funds invested in accordance with this Section 6.3. The Collateral Agent shall have no duty or obligation
regarding the reinvestment of any such funds in the absence of updated written instructions from the Issuer in form and substance reasonably satisfactory to the Collateral Agent.

(b) Each Secured Party shall be free to act independently on any issue not affecting the Collateral. Each Secured Party shall give prior notice
to the Collateral Agent of any such action that could materially affect the rights or interests of the Collateral Agent or the other Secured Parties to the extent that such notice is reasonably practicable. If such prior notice is not given, such
Secured Party shall give prompt notice following any action taken hereunder. 
 (c) Any proceeds of the Collateral received by any Secured
Party as a result of, or during, any Bankruptcy Proceeding will be delivered promptly to the Collateral Agent for distribution in accordance with Section 5.3.

(a) The Grantors assume all responsibility and liability arising from or relating to the use, maintenance, storage, sale, collection,
foreclosure, realization on, conveyance or other disposition of or involving the Collateral. The Obligations shall not be affected by any failure of any Grantor, the Collateral Agent or the Trustee to take any steps to perfect the Collateral
Agent’s Liens or to collect or realize upon the Collateral, nor shall loss of or damage to the Collateral release any Grantor from any of the Obligations. Following the occurrence and 

  
 26 








 
during the continuation of an Event of Default, the Collateral Agent may (but shall not be required to), and at the direction of the Trustee shall, subject to each Intercreditor Agreement (if
any) and the terms of the Indenture, without notice to or consent from any Grantor sue upon or otherwise collect, extend the time for payment of, modify or amend the terms of, compromise or settle for cash, credit, or otherwise upon any terms, grant
other indulgences, extensions, renewals, compositions, or releases, and take or omit to take any other action with respect to the Collateral, any security therefor, any agreement relating thereto, any insurance applicable thereto, or any Person
liable directly or indirectly in connection with any of the foregoing, without discharging or otherwise affecting the liability of any Grantor for the Obligations or under the Indenture, any other Indenture Document or any other agreement now or
hereafter existing between any Secured Party and any Grantor. 
 (b) It is expressly agreed by the Grantors that, anything herein to the
contrary notwithstanding, each of the Grantors shall remain liable under each of its contracts and each of its licenses to observe and perform all the conditions and obligations to be observed and performed by it thereunder. The Collateral Agent and
the Trustee shall not have any obligation or liability under any contract or license by reason of or arising out of this Agreement or the granting herein of a Lien thereon or the receipt by the Collateral Agent or the Trustee of any payment relating
to any contract or license pursuant hereto that is applied as required herein. The Collateral Agent and the Trustee shall not be required or obligated in any manner to perform or fulfill any of the obligations of any Grantor under or pursuant to any
contract or license, or to make any payment, or to make any inquiry as to the nature or the sufficiency of any payment received by it or the sufficiency of any performance by any party under any contract or license, or to present or file any claims,
or to take any action to collect or enforce any performance or the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times. 

Section 7.2 Right to Cure. The Collateral Agent may, (but shall not be required to) in its reasonable discretion, subject to each
Intercreditor Agreement (if any), pay any reasonable amount or do any reasonable act required of any Grantor hereunder or under any other Indenture Document in order to preserve, protect, maintain, or enforce the Obligations, the Collateral or the
Collateral Agent’s Liens therein, and which any Grantor fails to timely pay or do, including payment of any judgment against any Grantor, any insurance premium, any warehouse charge, any finishing or processing charge, any landlord’s or
bailee’s claim, and any other Lien upon or with respect to the Collateral. All payments that the Collateral Agent makes under this Section 7.2 and all reasonable
out-of-pocket costs and expenses that the Collateral Agent pays or incurs in connection with any action taken by it hereunder shall be promptly reimbursed by such
Grantor. Any payment made or other action taken by the Collateral Agent under this Section 7.2 shall be without prejudice to any right to assert an Event of Default hereunder and to proceed thereafter as herein provided. 

Section 7.3 Confidentiality. 

(a) The Collateral Agent, in its individual capacity and as Collateral Agent, and the Trustee, in its individual capacity and as Trustee, agree
and acknowledge that all information provided to the Collateral Agent or the Trustee by any Grantor may be considered to be proprietary and confidential information (“Confidential Information”). The Trustee and the


  
 27 








 
Collateral Agent each agrees to take all reasonable precautions necessary to keep such information confidential, which precautions shall be no less stringent than those that the Collateral Agent
and the Trustee, as applicable, employs to protect its own confidential information. Each of the Collateral Agent and the Trustee shall not disclose to any third party other than as set forth herein, and shall not use for any purpose other than the
exercise of the Collateral Agent’s and the Trustee’s rights and the performance of its respective obligations under this Agreement, any such information without the prior written consent of such Grantor, as applicable. Each of the
Collateral Agent and the Trustee shall limit access to such information received hereunder to (a) its directors, officers, managers and employees and (b) its legal advisors, to each of whom disclosure of such information is necessary for
the purposes described above; provided, however, that in each case such party has expressly agreed to maintain such information in confidence under terms and conditions substantially identical to the terms of this Section 7.3(a). 

(b) Each of the Collateral Agent and the Trustee agree that each Grantor does not have any responsibility whatsoever for any reliance on
Confidential Information by the Collateral Agent or the Trustee or by any Person to whom such information is disclosed in connection with this Agreement, whether related to the purposes described above or otherwise. Without limiting the generality
of the foregoing, each of the Collateral Agent and the Trustee agrees that the Grantor makes no representation or warranty whatsoever to it with respect to Confidential Information or its suitability for such purposes. Each of the Collateral Agent
and the Trustee further agrees that it shall not acquire any rights against the Grantor or any employee, officer, director, manager, representative or agent of the Grantor (together with the Issuer, “Confidential Parties”) as a
result of the disclosure of Confidential Information to the Trustee and that no Confidential Party has any duty, responsibility, liability or obligation to any Person as a result of any such disclosure. 

(c) In the event the Collateral Agent or the Trustee is required to disclose any Confidential Information received hereunder in order to comply
with any laws, regulations or court orders, it may disclose Confidential Information only to the extent necessary for such compliance; provided, however, that it shall give the Grantor, reasonable advance written notice of any such
court proceeding in which such disclosure may be required pursuant to a court order so as to afford the Grantor full and fair opportunity to oppose the issuance of such order and to appeal therefrom and shall cooperate reasonably with the Grantor,
as applicable, in opposing such order and in securing confidential treatment of any Confidential Information to be disclosed and/or obtaining a protective order narrowing the scope of such disclosure. 

Section 7.4 Power of Attorney. Each Grantor, as to itself, hereby appoints the Collateral Agent and the Collateral Agent’s
designee as such Grantor’s attorney, with power upon the occurrence and during the continuance of an Event of Default: (a) to endorse such Grantor’s name on any checks, notes, acceptances, money orders, or other forms of payment or
security that come into the Collateral Agent’s or any Secured Parties’ possession; (b) to sign such Grantor’s name on any invoice, bill of lading, warehouse receipt, or other document of title relating to any Collateral, on
drafts against customers, on assignments of Accounts, on notices of assignment, financing statements, and other public records and to file any such financing statements by electronic means with or without a signature as authorized or required by
applicable law or filing procedure; (c) to notify the post office authorities to change the address 

  
 28 








 
for delivery of such Grantor’s mail to an address designated by the Collateral Agent and to receive, open, and dispose of all mail addressed to such Grantor; (d) to send requests for
verification of Accounts to customers or Account Debtors (but if any such Accounts constitute ABL First Lien Collateral, only so long as no Senior Liens are outstanding on such Collateral); (e) to clear Inventory through customs in such
Grantor’s name, the Collateral Agent’s name, or the name of the Collateral Agent’s designee, and to sign and deliver to customs officials powers of attorney in such Grantor’s name for such purpose; and (f) to do all things
the Collateral Agent reasonably determines are necessary to carry out the security interest provisions of the Indenture and the provisions of this Agreement. Each Grantor ratifies and approves all acts of such attorney. Notwithstanding anything in
this Agreement or any Indenture Document to the contrary, none of the Trustee, the Collateral Agent, nor their attorneys, employees or Affiliates will be liable for any acts or omissions or for any error of judgment or mistake of fact or law other
than any such liability arising from any such Person’s gross negligence or willful misconduct, as finally determined by a court of competent jurisdiction. Notwithstanding the foregoing, any rights and remedies provided in this Section 7.4
shall be subject to each Intercreditor Agreement (if any). 
 Section 7.5 NATURE OF APPOINTMENT; LIMITATION OF DUTY. THE
APPOINTMENT OF THE COLLATERAL AGENT AS ATTORNEY-IN-FACT IN THIS ARTICLE VII IS COUPLED WITH AN INTEREST AND SHALL BE IRREVOCABLE UNTIL THE DATE ON WHICH THIS AGREEMENT IS TERMINATED IN ACCORDANCE WITH SECTION 8.13. NOTWITHSTANDING ANYTHING
CONTAINED IN THIS AGREEMENT OR IN ANY INDENTURE DOCUMENT, NEITHER THE COLLATERAL AGENT, NOR ANY SECURED PARTY, NOR ANY OF THEIR RESPECTIVE AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR REPRESENTATIVES SHALL HAVE ANY DUTY TO EXERCISE ANY
RIGHT OR POWER GRANTED HEREUNDER OR OTHERWISE OR TO PRESERVE THE SAME AND SHALL NOT BE LIABLE FOR ANY FAILURE TO DO SO OR FOR ANY DELAY IN DOING SO, EXCEPT TO THE EXTENT SUCH DAMAGES ARE ATTRIBUTABLE TO THEIR OWN GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT AS FINALLY DETERMINED BY A COURT OF COMPETENT JURISDICTION; PROVIDED THAT, IN NO EVENT SHALL THEY BE LIABLE FOR ANY PUNITIVE, EXEMPLARY, INDIRECT OR CONSEQUENTIAL DAMAGES.

 29 








 
Without limiting the foregoing, the rights, privileges, protections and benefits given to the Collateral Agent under the Indenture are extended to, and shall be enforceable by, the Collateral

Agreement and the other Indenture Documents to which it is a party. 
 (c) Absence of Fiduciary Relation. The Collateral Agent
undertakes to perform or to observe only such of its agreements and obligations as are specifically set forth in this Agreement, the Indenture and the other Indenture Documents, and no implied agreements, covenants or obligations with respect to any
Grantor or any Affiliate of any Grantor, any Secured Party or any other party shall be read into this Agreement against the Collateral Agent. The Collateral Agent in its capacity as such is not a fiduciary of and shall not owe or be deemed to owe
any fiduciary duty to any Grantor or any Related Person of any Grantor.

Collateral Agent be responsible for or have any obligation, duty or liability with respect to the creation, perfection, priority, maintenance, protection or enforcement of any Lien on, security interest in, pledge or other encumbrance involving or
relating to the Collateral or any other assets, properties or rights of the Grantors, provided, however that the Collateral Agent acknowledges that with respect to the enforcement of any Liens, its actions will be subject to each

safekeeping and physical preservation of the Collateral in its possession, under the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account and the Collateral Agent shall
be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which comparable secured parties accord comparable collateral. None
of the Collateral Agent or the Trustee 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

Agent and any Secured Party the amount of any and all reasonable out-of-pocket fees, costs and expenses (including the reasonable fees and expenses of their respective counsel, any special consultants reasonably engaged (and, unless an Event of
Default exists, engaged only with the consent of the Issuer), and any local counsel who might reasonably be retained by the Collateral Agent or any Secured Party, as the case may be, in connection with the transactions contemplated hereby) that the
Collateral Agent or any Secured Party, as the case may be, may incur in connection with (i) any Event of Default, including the sale, lease, license or other disposition of, collection from, or other realization upon, any of the Collateral

Document, unless such Secured Party shall have offered to the Collateral Agent reasonable security or indemnity against the costs, expenses and liabilities which may be incurred by it in compliance with such request, order or direction.

 33 








 Section 8.3 Limitation on Collateral Agent’s and Secured Party’s Duty with
Respect to the Collateral. The Collateral Agent shall have no obligation to clean-up or otherwise prepare the Collateral for sale. The Collateral Agent and each Secured Party shall use reasonable care with respect to the Collateral in its
possession or under its control. Neither the Collateral Agent nor any Secured Party shall have any other duty as to any Collateral in its possession or control or in the possession or control of any agent or nominee of the Collateral Agent or such
Secured Party, or any income thereon (other than to account for proceeds therefrom) or as to the preservation of rights against prior parties or any other rights pertaining thereto. To the extent that applicable law imposes duties on the Collateral
Agent to exercise remedies in a commercially reasonable manner, and to the extent permitted by applicable law, each Grantor acknowledges and agrees that it would be commercially reasonable for the Collateral Agent (i) to fail to incur expenses
deemed significant by the Collateral Agent to prepare Collateral for disposition or otherwise to transform raw material or work in process into finished goods or other finished products for disposition, (ii) to fail to obtain third party
consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (iii) to
fail to exercise collection remedies against Account Debtors or other Persons obligated on Collateral or to remove Liens on or any adverse claims against Collateral, (iv) to exercise collection remedies against Account Debtors and other Persons
obligated on Collateral directly or through the use of collection agencies and other collection specialists, (v) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a
specialized nature, (vi) to contact other Persons, whether or not in the same business as the Grantor, for expressions of interest in acquiring all or any portion of such Collateral, (vii) to hire one or more professional auctioneers to
assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature, (viii) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or
that have the reasonable capacity of doing so, or that match buyers and sellers of assets, (ix) to dispose of assets in wholesale rather than retail markets, (x) to disclaim disposition warranties, such as title, possession or quiet
enjoyment, (xi) to purchase insurance or credit enhancements to insure the Collateral Agent against risks of loss, collection or disposition of Collateral or to provide to the Collateral Agent a guaranteed return from the collection or
disposition of Collateral, or (xii) to the extent deemed appropriate by the Collateral Agent, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist the Collateral Agent in the collection or
disposition of any of the Collateral. Each Grantor acknowledges that the purpose of this Section 8.3 is to provide non-exhaustive indications of what actions or omissions by the Collateral Agent would be commercially reasonable in the
Collateral Agent’s exercise of remedies against the Collateral and that other actions or omissions by the Collateral Agent shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 8.3. Without
limitation upon the foregoing, nothing contained in this Section 8.3 shall be construed to grant any rights to any Grantor or to impose any duties on the Collateral Agent that would not have been granted or imposed by this Agreement or by
applicable law in the absence of this Section 8.3. 
 Section 8.4 Compromises and Collection of Collateral. Each Grantor
and the Collateral Agent recognize that setoffs, counterclaims, defenses and other claims may be asserted by obligors with respect to certain of the Accounts, that certain of the Accounts may be or become uncollectible in whole or in part and that
the expense and probability of success in 

  
 34 








 
litigating a disputed Account may exceed the amount that reasonably may be expected to be recovered with respect to an Account. In view of the foregoing, each Grantor agrees that the Collateral
Agent may at any time and from time to time if an Event of Default has occurred and is continuing, (provided that if such Account constitutes ABL First Lien Collateral only so long as no Senior Liens are outstanding in on such Collateral),
compromise with the obligor on any Account, accept in full payment of any Account such amount as the Collateral Agent in its sole discretion shall determine or abandon any Account, and any such action by the Collateral Agent shall be commercially
reasonable so long as the Collateral Agent acts in good faith based on information known to it at the time it takes any such action. 

Section 8.5 Specific Performance of Certain Covenants. Each Grantor acknowledges and agrees that a breach of any of the covenants
contained in Sections 4.2(a), 4.5, 4.6, 4.7, 4.8, 4.10, 4.12, 5.1(j), 7.6, 8.11, 8.17 and 8.18, will cause irreparable injury to the Collateral Agent and the other Secured Parties, that the Collateral Agent and the other Secured Parties have no
adequate remedy at law in respect of such breaches and therefore agrees, without limiting the right of the Collateral Agent or the other Secured Parties to seek and obtain specific performance of other obligations of any Grantor contained in this
Agreement, that the covenants of such Grantor contained in the Sections referred to in this Section 8.5 shall be specifically enforceable against such Grantor. 

Section 8.6 Cumulative Remedies; No Prior Recourse to Collateral. The enumeration herein of the Collateral Agent’s and the
Trustee’s rights and remedies is not intended to be exclusive, and such rights and remedies are in addition to and not by way of limitation of any other rights or remedies that the Collateral Agent and the Trustee may have under the UCC, other
applicable law or the Indenture Documents. The Collateral Agent and the Trustee shall have the right, in their sole discretion, to determine which rights and remedies are to be exercised and in which order. The exercise of one right or remedy shall
not preclude the exercise of any others, all of which shall be cumulative. The Collateral Agent and the Trustee may, without limitation, proceed directly against any Person liable therefor to collect the Obligations without any prior recourse to the
Collateral. No failure to exercise and no delay in exercising, on the part of the Collateral Agent or the Trustee, any right, remedy, power, or privilege hereunder, shall operate as a waiver thereof, nor shall any single or partial exercise of any
right, remedy, power, or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power, or privilege. 

Section 8.7 Limitation by Law; Severability of Provisions. All rights, remedies and powers provided in this Agreement may be
exercised only to the extent that the exercise thereof does not violate any applicable provision of law, and all the provisions of this Agreement are intended to be subject to all applicable mandatory provisions of law that may be controlling and to
be limited to the extent necessary so that they shall not render this Agreement invalid, unenforceable or not entitled to be recorded or registered, in whole or in part. The illegality or unenforceability of any provision of this Agreement or any
instrument or agreement required hereunder shall not in any way affect or impair the legality or enforceability of the remaining provisions of this Agreement or any instrument or agreement required hereunder. 

  
 35 








 Section 8.8 Reinstatement. This Agreement shall remain in full force and effect and
continue to be effective should any petition be filed by or against any Grantor for liquidation or reorganization, should any Grantor become insolvent or make an assignment for the benefit of any creditor or creditors or should a receiver or trustee
be appointed for all or any significant part of such Grantor’s assets. This Agreement shall continue to be effective or be reinstated, as the case may be, if at any time when there is or has been more than one Grantor payment and performance of
the Obligations, or any part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee of the Obligations, whether as a “voidable preference,” “fraudulent
conveyance,” or otherwise, all as though such payment or performance had not been made. In the event that any such payment, or any part thereof, is rescinded, reduced, restored or returned, the Obligations shall be reinstated and deemed reduced
only by such amount paid and not so rescinded, reduced, restored or returned. 
 Section 8.9 Binding Effect. The provisions of
this Agreement shall be binding upon and inure to the benefit of the respective representatives, successors, and permitted assigns of the parties hereto; provided, however, no Grantor shall assign or delegate any of its rights or
duties hereunder without the prior written consent of the Collateral Agent and the Trustee (other than pursuant to a transaction permitted under the Indenture), and any attempted assignment without such consent shall be null and void. The rights and
benefits of the Collateral Agent and the Trustee hereunder shall, if such Persons so agree, inure to any party acquiring any interest in the Obligations or any part thereof in accordance with the terms hereof or of the Indenture. 

Section 8.10 Survival of Representations. All representations and warranties made by the Grantors in the Indenture Documents and
in the certificates or other instruments prepared or delivered in connection with or pursuant to this Agreement or any other Indenture Document shall be considered to have been relied upon by the Secured Parties and shall survive the execution and
delivery of the Indenture Documents and the purchase of the Securities by the Purchasers, regardless of any investigation made by any Secured Party or on its behalf and notwithstanding that the Collateral Agent, the Trustee or any other Secured
Party may have had notice or knowledge of any Default or incorrect representation or warranty. Notwithstanding anything to the contrary set forth herein, the provisions of Section 8.17 and 8.18 shall survive and remain in full force and effect
regardless of the consummation of the transactions contemplated hereby, the repayment of the Securities or the termination of this Agreement or any other Indenture Document. 

Section 8.11 Guaranties; Third Party Joinder. Promptly upon creation or acquisition of any Subsidiary of a Grantor, such Grantor
shall, to the extent required pursuant to the terms of the Indenture, cause such new Subsidiary to become a Grantor by executing and delivering to the Collateral Agent such an instrument in the form of Exhibit H hereto and other
instruments, certificates, and agreements as the Collateral Agent may reasonably request. Upon execution and delivery of such instruments, certificates, and agreements, such newly created or acquired Subsidiary shall automatically become a Grantor
and thereupon shall have all of the rights, benefits, duties, and obligations of a Grantor under the Indenture Documents.

 WHEREAS
Section 8.11 of the Agreement and Section 4.10 of the Indenture provide that additional Wholly Owned Restricted Subsidiaries of the Issuer shall become Subsidiary Parties under the Agreement by execution and delivery of an instrument in

terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Indenture and the Agreement. 







 Accordingly, the Collateral Agent and the New Subsidiary agree as follows: 

SECTION 1. In accordance with Section 8.11 of the Agreement, the New Subsidiary by its signature below becomes a Subsidiary Party and a
Grantor under the Agreement with the same force and effect as if originally named therein as a Subsidiary Party and the New Subsidiary hereby expressly assumes, and hereby agrees to perform and observe, each and every one of the covenants, rights
promises, agreements, terms, conditions, obligations, appointments, duties and liabilities applicable to it as a Subsidiary Party and Grantor thereunder and all other Indenture Documents applicable to it as a Subsidiary Party and Grantor under the
Agreement. By virtue of the foregoing, the New Subsidiary hereby accepts and assumes any liability of a Grantor (as to itself only) related to each representation, warranty, covenant or obligation made by a Grantor (as to itself only) in the
Agreement and hereby expressly affirms, as of the date hereof, each of such representations, warranties, covenants and obligations. In furtherance of the foregoing, the New Subsidiary, as security for the payment and performance in full of the
Obligations, does hereby create and grant to the Collateral Agent, its successors and assigns, for the benefit of the Secured Parties, their successors and assigns, a security interest in and Lien on all of the New Subsidiary’s right, title and
interest in and to the Collateral of the New Subsidiary. Each reference to a “Grantor” in the Agreement shall be deemed to include the New Subsidiary. The Agreement is hereby incorporated herein by reference. 

SECTION 2. The New Subsidiary represents and warrants to the Collateral Agent and the other Secured Parties that (a) the New Subsidiary
has the requisite [corporate, partnership or company] power and authority to enter into and perform its obligations under this Supplement and that this Supplement has been duly authorized, executed and delivered by it and constitutes its legal,
valid and binding obligation, enforceable against it in accordance with its terms, (b) the representations and warranties set forth in the Agreement are true and correct in all material respects on and as of the date hereof as such
representations and warranties apply to the New Subsidiary (except to the extent that any such representations and warranties expressly relate to an earlier date) with the same force and effect as if made on the date hereof and (c) as of the
date hereof, the New Subsidiary is “located” (as such term is used in Article 9-307 of the UCC) in the state of [Delaware]. 

SECTION 3. This Supplement 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. This Supplement shall become effective when the Collateral Agent shall have received a counterpart of this Supplement that bears the signature of the
New Subsidiary and the Collateral Agent has executed a counterpart hereof. Delivery of an executed signature page to this Supplement by facsimile transmission or by email shall be as effective as delivery of a manually signed counterpart of this
Supplement. 
 SECTION 4. The New Subsidiary hereby represents and warrants that set forth on Schedule I attached hereto is a copy of a
fully completed Perfection Certificate executed by the New Subsidiary. The information contained in the Perfection Certificate delivered by the New Subsidiary is correct and complete in all material respects as of the date hereof. 

SECTION 5. Except as expressly supplemented hereby, the Agreement shall remain in full force and effect. 







 SECTION 6. THIS SUPPLEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF
THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW (OTHER THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW), EXCEPT TO THE EXTENT THAT LOCAL LAW GOVERNS THE CREATION, PERFECTION, PRIORITY OR ENFORCEMENT OF
SECURITY INTERESTS. 
 SECTION 7. In case any one or more of the provisions contained in this Supplement should be held invalid, illegal
or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and in the Agreement shall not in any way be affected or impaired thereby (it being understood that the invalidity of a
particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions. 

SECTION 8. All communications and notices hereunder shall be in writing and given as provided in Section 8.1 of the Agreement. 

SECTION 9. The New Subsidiary agrees to reimburse the Collateral Agent for its reasonable out-of-pocket expenses in connection with this
Supplement, including the reasonable fees, other charges and disbursements of counsel for the Collateral Agent. 
 SECTION 10.
Notwithstanding any other provision contained herein, the Agreement, the Liens created thereby and the rights, remedies, duties and obligations provided for therein and herein are subject in all respects to the provisions of each Intercreditor
Agreement (if any) and, to the extent provided therein, the applicable Senior Security Documents (as defined in the applicable Intercreditor Agreement). In the event of any conflict or inconsistency between the provisions of the Agreement, this
Supplement and any Intercreditor Agreement, the provisions of the applicable Intercreditor Agreement shall control. 
 SECTION 11. It is
expressly understood and agreed that U.S. Bank National Association is entering into this Supplement solely in its capacity as Collateral Agent as appointed pursuant to the Indenture, and shall be entitled to all of the rights, privileges,
immunities and protections under the Indenture as if such rights, privileges, immunities and protections were set forth herein. 
 SECTION
12. Notwithstanding anything to the contrary herein, in any Indenture Document or any ABL Document (as such term is defined in each Intercreditor Agreement (if any)), the Grantors shall not be required to act or refrain from acting (a) pursuant
to any Indenture Document solely with respect to any ABL First Lien Collateral in any manner that would cause a default under any ABL Document, or (b) pursuant to any ABL Document solely with respect to any Noteholder First Lien Collateral in
any manner that would cause a default under any Indenture Document. For avoidance of doubt and for the purposes of this paragraph only, the terms Indenture Document and ABL Document do not include any Intercreditor Agreement. 







 IN WITNESS WHEREOF, the New Subsidiary and the Collateral Agent have duly executed this
Supplement to the Agreement as of the day and year first above written.
