Collateral shall be at a location other than as set forth on Schedule I hereto as the same may be supplemented in accordance with the terms hereof), notifying such Person of the Collateral Agents security interest created hereby and
obtaining a written acknowledgment from such Person that such Person holds possession of the Collateral for the benefit of the Collateral Agent, (F) if at any time after the date hereof, any Grantor acquires or holds any Commercial Tort Claim
in excess of $100,000 individually or $500,000 in the aggregate, promptly notifying the Collateral Agent in a writing signed by such Grantor setting forth a brief description of such Commercial Tort Claim and granting to the Collateral Agent a
security interest therein and in the proceeds thereof, which writing shall incorporate the provisions hereof, (G) upon the acquisition after the date hereof by any Grantor of any motor vehicle or other Equipment subject to a certificate of
title or ownership (other than a Motor Vehicle or Equipment that is subject to a purchase money security interest), causing the Collateral Agent to be listed as the lienholder on such certificate of title or ownership and delivering evidence of the
same to the Collateral Agent in accordance with Section 5(j) hereof; and (H) taking all actions required by any earlier versions of the Uniform Commercial Code or by other law, as applicable, in any relevant Uniform Commercial Code
jurisdiction, or



-11-



---

by other law as applicable in any foreign jurisdiction. No Grantor shall acquire or shall move to a location outside of the United States any assets that currently are or typically would be
acquired and held in the United States.

(b) Location of Equipment and Inventory. Other than any Inventory, or
Equipment in transit (or, in the case of Grantors motor vehicles, being used in the ordinary course), or in the possession of third parties for repair, assembly or refurbishment, each Grantor will keep the Equipment and Inventory (i) at
the locations specified therefor on Part B of Schedule I hereto, or (ii) at such other locations set forth on Part B of Schedule I hereto (or a new Part B of Schedule I delivered by the Grantors to Collateral Agent from
time to time), or (iii) at such other locations in the United States, provided that within 20 days following the relocation of Equipment or Inventory to such other location or the acquisition of Equipment or Inventory, such Grantor shall
deliver to the Collateral Agent a new Part B of Schedule I indicating such new locations.

(c) Condition of
Equipment. Each Grantor will maintain or cause the Equipment (necessary or useful to its business) to be maintained and preserved in good condition, repair and working order, ordinary wear and tear excepted, and will forthwith, or in the case of
any loss or damage to any Equipment of any Grantor within a commercially reasonable time after the occurrence thereof, make or cause to be made all repairs, replacements and other improvements in connection therewith which are necessary or
desirable, consistent with past practice, or which the Collateral Agent may request to such end. Any Grantor will promptly furnish to the Collateral Agent a statement describing in reasonable detail any such loss or damage in excess of $250,000 per
occurrence to any Equipment.

(d) Taxes, Etc. Each Grantor agrees to pay promptly when due all property and other
taxes, assessments and governmental charges or levies imposed upon, and all claims (including claims for labor, materials and supplies) against, the Equipment and Inventory, except to the extent the validity thereof is being contested in good faith
by proper proceedings which stay the imposition of any penalty, fine or Lien resulting from the non-payment thereof and with respect to which adequate reserves in accordance with GAAP have been set aside for the payment thereof.

(e) Insurance.

(i) Each Grantor will, at its own expense, maintain insurance (including, without limitation, commercial general liability and property insurance) in such amounts, against such risks, in such form and
with responsible and reputable insurance companies or associations as is required by any Governmental Authority having jurisdiction with respect thereto or as is carried generally in accordance with sound business practice by companies in similar
businesses similarly situated and in any event, in amount, adequacy and scope reasonably satisfactory to the Collateral Agent. Each such policy for liability insurance shall provide for all losses to be paid on behalf of the Collateral Agent and any
Grantor as their respective interests may appear, and each policy for property damage insurance shall provide for all losses to be adjusted with, and paid directly to, the Collateral Agent. Each such policy shall (A) name the Collateral Agent
as an additional insured party thereunder (without any representation or warranty by or obligation upon the Collateral Agent) as their interests may



-12-



---

appear, (B) contain an agreement by the insurer that any loss thereunder shall be payable to the Collateral Agent on its own account notwithstanding any action, inaction or breach of
representation or warranty, or endorsement by any Grantor (or as specified in such insurers standard acord or other similar form), (C) provide that there shall be no recourse against the Collateral Agent for payment of
premiums or other amounts with respect thereto, and (D) provide that at least 30 days prior written notice of cancellation, lapse, expiration or other adverse change shall be given to the Collateral Agent by the insurer. Any Grantor will
deliver to the Collateral Agent original or duplicate policies of such insurance and a report of a reputable insurance broker with respect to such insurance. Any Grantor will also execute and deliver instruments of assignment of such insurance
policies and cause the respective insurers to acknowledge notice of such assignment.

(ii) Reimbursement under any liability
insurance maintained by any Grantor pursuant to this Section 5(e) may be paid directly to the Person who shall have incurred liability covered by such insurance. So long as no Default or Event of Default has occurred and is continuing, to the
extent any proceeds of insurance maintained by any Grantor pursuant to this Section 5(e) are paid to the Collateral Agent but another Security Document (as defined in the Indenture) permits the use of such funds by the Grantor, such proceeds
shall be remitted to such Grantor by the Collateral Agent for use in the manner described in such Security Document. Upon the occurrence and during the continuance of any Default or Event of Default, any proceeds of insurance maintained by any
Grantor pursuant to this Section 5(e) shall be paid to the Collateral Agent, and, the Collateral Agent, may, at its option, require any Grantor to make or cause to be made the necessary repairs to or replacements, and any proceeds of insurance
maintained by any Grantor and in possession of the Collateral Agent pursuant to this Section 5(e) shall be paid by the Collateral Agent to any Grantor as reimbursement for the costs of such repairs or replacements.

(f) Provisions Concerning the Accounts and the Licenses.

(i) Each Grantor will (A) give the Collateral Agent at least 30 days prior written notice of any change in such
Grantors name (including, for certainty, the adoption of any French form of name by a Canadian Grantor), identity or organizational structure, (B) maintain its jurisdiction of incorporation, organization or formation as set forth in Part
A of Schedule I hereto, (C) immediately notify the Collateral Agent upon obtaining an organizational identification number, if on the date hereof such Grantor did not have such identification number, and (D) keep adequate records
concerning the Accounts and Chattel Paper.

(ii) Each Grantor will, except as otherwise provided in this subsection (f),
continue to collect, at its own expense, all amounts due or to become due under the Accounts. In connection with such collections, any Grantor may (and, at the Collateral Agents direction, will) take such action as any Grantor or the
Collateral Agent may deem necessary or advisable to enforce collection or performance of the Accounts; provided, however, that the Collateral Agent shall have the right at any time, upon the occurrence and during the continuance of an Event of
Default, to notify the account debtors or obligors under any Accounts of the assignment of such Accounts to the Collateral Agent and to direct such account debtors or obligors to make payment of all amounts due or to become due to any Grantor
thereunder directly to the Collateral Agent or its designated agent and, upon such notification and at the



-13-



---

expense of any Grantor and to the extent permitted by law, to enforce collection of any such Accounts and to adjust, settle or compromise the amount or payment thereof, in the same manner and to
the same extent as any Grantor might have done. After receipt by any Grantor of a notice from the Collateral Agent that the Collateral Agent has notified, intends to notify, or has enforced or intends to enforce any Grantors rights against the
account debtors or obligors under any Accounts as referred to in the proviso to the immediately preceding sentence, (A) all amounts and proceeds (including Instruments) received by any Grantor in respect of the Accounts shall be received in
trust for the benefit of the Collateral Agent hereunder, shall be segregated from other funds of any Grantor and shall be forthwith paid over to the Collateral Agent in the same form as so received (with any necessary endorsement) to be applied as
specified in Section 7(b) hereof, and (B) no Grantor will adjust, settle or compromise the amount or payment of any Account or release wholly or partly any account debtor or obligor thereof or allow any credit or discount thereon. In
addition, upon the occurrence and during the continuance of an Event of Default, the Collateral Agent may (in its sole and absolute discretion) direct any or all of the banks and financial institutions with which any Grantor either maintains a
Deposit Account or a lockbox or deposits the proceeds of any Accounts to send immediately to the Collateral Agent by wire transfer (to such account as the Collateral Agent shall specify, or in such other manner as the Collateral Agent shall direct)
all or a portion of such securities, cash, investments and other items held by such institution. Any such securities, cash, investments and other items so received by the Collateral Agent shall be applied as specified in accordance with
Section 7(b) hereof.

(iii) Upon the occurrence and during the continuance of any breach or default under any material
License referred to in Part F of Schedule I hereto by any party thereto other than any Grantor, each Grantor party thereto will, promptly after obtaining knowledge thereof, give the Collateral Agent written notice of the nature and duration
thereof, specifying what action, if any, it has taken and proposes to take with respect thereto and thereafter will take reasonable steps to protect and preserve its rights and remedies in respect of such breach or default, or will obtain or acquire
an appropriate substitute License.

(iv) Each Grantor will, at its expense, promptly deliver to the Collateral Agent a copy
of each notice or other communication received by it by which any other party to any material License referred to in Part F of Schedule I hereto purports to exercise any of its rights or affect any of its obligations thereunder, together with
a copy of any reply by such Grantor thereto.

(v) Each Grantor will exercise promptly and diligently each and every right
which it may have under each material License (other than any right of termination) and will duly perform and observe in all respects all of its obligations under each material License and will, except as permitted by the Indenture, take all action
reasonably necessary to maintain such Licenses in full force and effect. Except as permitted by the Indenture, no Grantor will, cancel, terminate, amend or otherwise modify in any respect, or waive any provision of, any material License referred to
in Part F of Schedule I hereto.

(vi) Notwithstanding anything to the contrary contained in any other provision of
this Security Agreement, if any Grantor cannot lawfully grant the security interest contemplated hereby in any General Intangibles, Intellectual Property or Licenses or any rights



-14-



---

related thereto (each, an Operating Right) because the terms of such Operating Right prohibit the creation of the security interest contemplated hereby therein, the Operating
Right requires the consent of any Person which has not been obtained or the grant of the security interest contemplated hereby therein would contravene or is void under any applicable statute or regulation, that Operating Right shall not, to the
extent it would be illegal, void or result in a material loss and expense to such Grantor (each, a Prescribed Operating Right), be subject to the security interest contemplated hereby (save to the extent provided below) unless and
until such agreements, consents, waivers and approvals as may be required to avoid such illegality, voidness or material loss and expense have been obtained (Required Approvals). The security interest contemplated hereby shall
nonetheless immediately attach to any rights of such Grantor arising under, by reason of, or otherwise in respect of such Prescribed Operating Right, such as the right to receive payments thereunder and all Proceeds thereof (Related
Rights), to the extent and at the time such attachment to the Related Rights (i) is not illegal, void and would not result in a material loss and expense to such Grantor or (ii) in the case of Accounts, such prohibition or
restriction is not enforceable against third parties such as the Collateral Agent.

(vii) To the extent not prohibited by
applicable statute or regulation, each Grantor will hold in trust for the Collateral Agent on behalf of and for the rateable benefit of the Secured Parties, and provide the Secured Parties with the benefits of, each Prescribed Operating Right and
following the occurrence of an Event of Default and while it is continuing, will enforce all Prescribed Operating Rights at the direction of the Collateral Agent or at the direction of such other Person (including any purchaser of Collateral from
the Collateral Agent or any Receiver) as the Collateral Agent may designate, provided that until the security interest contemplated hereby becomes enforceable, such Grantor shall, to the extent permitted by the Indenture, be entitled to receive all
Proceeds relating to the Prescribed Operating Rights, subject to the security interest contemplated hereby.

(viii) Upon
request from the Collateral Agent from time to time, each Grantor shall use commercially reasonable efforts to obtain such Required Approvals as the Collateral Agent shall specify as soon as reasonably practicable.

(ix) None of the Collateral of any Canadian Grantor shall include Consumer Goods (as such term is defined in the PPSA).

(g) Transfers and Other Liens.

(i) No Grantor will sell, assign (by operation of law or otherwise), lease, license, exchange or otherwise transfer or dispose of any of the Collateral, except (A) Inventory in the ordinary course of
business, (B) worn out or obsolete assets, not necessary to the business, and (C) otherwise as permitted pursuant to the terms of the Indenture.

(ii) No Grantor will create, suffer to exist or grant any Lien upon or with respect to any Collateral other than a Permitted Lien.

(h) Intellectual Property.

(i) If applicable, any Grantor shall, upon
the Collateral Agents written request, duly execute and deliver the applicable Assignment for Security in the form attached



-15-

hereto as Exhibit A. Each Grantor (either itself or through licensees) will, and will cause each licensee thereof to, take all action necessary to maintain all of the material Intellectual
Property in full force and effect, including, without limitation, using the proper statutory notices and markings and using the Trademarks on each applicable trademark class of goods in order to so maintain the Trademarks in full force and free from
any claim of abandonment for non-use, and each Grantor will not (nor permit any licensee thereof to) do any act or knowingly omit to do any act whereby any material Intellectual Property may become invalidated; provided, however, that so long as no
Event of Default has occurred and is continuing, no Grantor shall have an obligation to use or to maintain any Intellectual Property (A) that relates solely to any product or work, that has been, or is in the process of being, discontinued,
abandoned or terminated, (B) that is being replaced with Intellectual Property substantially similar to the Intellectual Property that may be abandoned or otherwise become invalid, so long as the failure to use or maintain such Intellectual
Property does not materially adversely affect the validity of such replacement Intellectual Property and so long as such replacement Intellectual Property is subject to the Lien created by this Agreement or (C) that is substantially the same as
another Intellectual Property that is in full force, so long the failure to use or maintain such Intellectual Property does not materially adversely affect the validity of such replacement Intellectual Property and so long as such other Intellectual
Property is subject to the Lien and security interest created by this Agreement. Each Grantor will cause to be taken all commercially reasonable and necessary steps in any proceeding before each applicable Intellectual Property Office to maintain
each registration or application for registration of the material Intellectual Property (for the avoidance of doubt, other than any Intellectual Property described in the proviso to the immediately preceding sentence), including, without limitation,
filing of renewals, affidavits of use, affidavits of incontestability and opposition, interference and cancellation proceedings and payment of maintenance fees, filing fees, taxes or other governmental fees. If any Intellectual Property (other than
Intellectual Property described in the proviso to the first sentence of subsection (i) of this clause (h)) is infringed, misappropriated, diluted or otherwise violated in any material respect by a third party, each Grantor shall (x) upon
learning of such infringement, misappropriation, dilution or other violation, promptly notify the Collateral Agent and (y) to the extent any Grantor shall deem commercially reasonable and appropriate under the circumstances, promptly sue for
infringement, misappropriation, dilution or other violation, seek injunctive relief where appropriate and recover any and all damages for such infringement, misappropriation, dilution or other violation, or take such other actions as such Grantor
shall deem appropriate under the circumstances to protect such Intellectual Property. Each Grantor shall furnish to the Collateral Agent from time to time upon its request statements and schedules further identifying and describing the Registered
Intellectual Property, material Trade Secrets and material Licenses and such other reports in connection with the Registered Intellectual Property, material Trade Secrets and material Licenses, all in reasonable detail, following receipt by the
Collateral Agent of any such statements, schedules or reports, each Grantor shall modify this Agreement by amending Parts F, G and H of Schedule I hereto, as the case may be, to include any Registered Intellectual Property, material Trade
Secret and material License, as the case may be, which becomes part of the Collateral under this Agreement and shall execute and authenticate such documents and do such acts as shall be necessary or, in the reasonable judgment of the Collateral
Agent, desirable to subject such Intellectual Property and material Licenses to the Lien and security interest created by this Agreement. Notwithstanding anything herein to the contrary, upon the occurrence and during the continuance of an Event of
Default, no



-16-



---

Grantor may abandon or otherwise permit any Intellectual Property to become invalid without the prior written consent of the Collateral Agent, and if any Intellectual Property is infringed,
misappropriated, diluted or otherwise violated in any material respect by a third party, each Grantor will take such action as necessary or as the Collateral Agent shall deem appropriate under the circumstances to protect such Intellectual Property.

(ii) In no event shall any Grantor, either itself or through any agent, employee, licensee or designee, file an application
for the registration of any Trademark or Copyright or the issuance of any Patent with any Intellectual Property Office, or in any similar office or agency of the United States unless it gives the Collateral Agent written notice within thirty
(30) days of such filing. Any Grantor shall execute, authenticate and deliver any and all assignments, agreements, instruments, documents and papers necessary to evidence the Collateral Agents security interest hereunder in such
Intellectual Property and the General Intangibles of any Grantor relating thereto or represented thereby, and each Grantor hereby appoints the Collateral Agent its attorney-in-fact to execute and/or authenticate and file all such writings for the
foregoing purposes, all acts of such attorney being hereby ratified and confirmed, and such power (being coupled with an interest) shall be irrevocable until the indefeasible payment in full in cash of all of the Obligations in full.

(i) Deposit, Commodities and Securities Accounts. Each Grantor shall cause each bank and other financial institution with an
account referred to in Part E of Schedule I hereto to execute and deliver to the Collateral Agent a control agreement, in form and substance reasonably satisfactory to the Collateral Agent, duly executed by each Grantor and such bank or
financial institution, or enter into other arrangements in form and substance satisfactory to the Collateral Agent, pursuant to which such institution shall irrevocably agree, inter alia, that (i) it will comply at any time with
the instructions originated by the Collateral Agent to such bank or financial institution directing the disposition of cash, Commodity Contracts, securities, Investment Property and other items from time to time credited to such account, without
further consent of each Grantor, which instructions the Collateral Agent will not give to such bank or other financial institution in the absence of a continuing Event of Default, (ii) all Commodity Contracts, securities, Investment Property
and other items of each Grantor deposited with such institution shall be subject to a perfected, first priority security interest in favor of the Collateral Agent, (iii) any right of set off (other than recoupment of standard fees),
bankers Lien or other similar Lien, security interest or encumbrance shall be fully waived as against the Collateral Agent, and (iv) upon receipt of written notice from the Collateral Agent during the continuance of an Event of Default,
such bank or financial institution shall immediately send to the Collateral Agent by wire transfer (to such account as the Collateral Agent shall specify, or in such other manner as the Collateral Agent shall direct) all such cash, the value of any
Commodity Contracts, securities, Investment Property and other items held by it. Without the prior written consent of the Collateral Agent, each Grantor shall not make or maintain any Deposit Account, Commodity Account or Securities Account except
for the accounts set forth in Part E of Schedule I hereto. The provisions of this paragraph 5(i) shall not apply to (i) Deposit Accounts for which the Collateral Agent is the depositary (ii) Deposit Accounts specially and
exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of each Grantors salaried or hourly employees and (iii) Deposit Accounts which individually and in the aggregate, have an
average monthly balance of $10,000 or less.

(j) Motor Vehicles. With respect to any motor vehicles in excess of $100,000

(i) Each Grantor shall deliver to the Collateral Agent originals of the certificates of title or ownership for all such motor vehicles
owned by it with the Collateral Agent listed as lienholder, for the benefit of the Secured Parties.

(ii) Each Grantor hereby
appoints the Collateral Agent as its attorney-in-fact, effective the date hereof and terminating upon the termination of this Agreement, for the purpose of (A) executing on behalf of such Grantor title or ownership applications for filing with
appropriate state agencies to enable such motor vehicles now owned or hereafter acquired by such Grantor to be retitled and the Collateral Agent listed as lienholder thereof, (B) filing such applications with such state agencies, and
(C) executing such other documents and instruments on behalf of, and taking such other action in the name of, such Grantor as necessary or as the Collateral Agent may deem necessary or advisable to accomplish the purposes hereof (including,
without limitation, for the purpose of creating in favor of the Collateral Agent a perfected Lien on such motor vehicles and exercising the rights and remedies of the Collateral Agent hereunder). This appointment as attorney-in-fact is coupled with
an interest and is irrevocable until all of the Obligations are indefeasibly paid in full in cash.

(iii) So long as no Event
of Default shall have occurred and be continuing, upon the request of any Grantor, the Collateral Agent shall execute and deliver to any Grantor such instruments as any Grantor shall reasonably request or as otherwise provided for in the Indenture
to remove the notation of the Collateral Agent as lienholder on any certificate of title for any motor vehicle; provided, however, that any such instruments shall be delivered, and the release effective, only upon receipt by the
Collateral Agent of a certificate from any Grantor stating that such motor vehicle is to be sold or has suffered a casualty loss (with title thereto in such case passing to the casualty insurance company therefor in settlement of the claim for such
loss) and the amount that any Grantor will receive as sale proceeds or insurance proceeds.

(k) Control. Each Grantor
hereby agrees to take any or all action that may be necessary or that the Collateral Agent may reasonably request in order for the Collateral Agent to obtain control in accordance with Sections 9-105, 9-106 and 9-107 of the Uniform Commercial Code
with respect to the following Collateral (other than any Electronic Chattel Paper, Investment Property and Letter of Credit Rights having a value of less than, or having funds or other assets credited thereto with a value of less than, $100,000
individually or $500,000 in the aggregate): (i) Electronic Chattel Paper, (ii) Investment Property, and (iii) Letter-of-Credit Rights.

---

Grantors records and books of account, (ii) to visit and inspect its properties, (iii) to verify materials, leases, Instruments, Accounts, Inventory and other assets of any
Grantor from time to time, (iii) to conduct audits, physical counts, appraisals and/or valuations, examinations at the locations of any Grantor. Upon reasonable request, each Grantor shall also permit the Collateral Agent, or any agent or
representatives thereof or such professionals or other Persons as the Collateral Agent may designate to discuss such Grantors affairs, finances and accounts with any of its directors, officers, managerial employees, independent accountants or
any of its other representatives.

(n) Leases. The last day of the term of any lease, oral or written, or any agreement therefor, now held or
hereafter acquired by a Canadian Grantor shall be excepted from the security hereby constituted and shall not form part of the Collateral but such Grantor shall stand possessed of such one day remaining upon trust to assign and dispose of the same.
If any such lease or agreement therefor contains a provision which provides in effect that such lease or agreement may not be assigned, sub-leased, charged or made the subject of any Lien without the consent of the lessor, the application of the
security hereby constituted to any such lease or agreement shall be conditional upon such consent being obtained. Each Canadian Grantor shall forthwith use commercially reasonable best efforts to obtain, as soon as reasonably practicable, such
consent for each such lease or agreement that is material.

SECTION 6. Additional Provisions Concerning the
Collateral.

(a) To the maximum extent permitted by applicable law, and for the purpose of taking any action that is
necessary or that the Collateral Agent may deem necessary or advisable to accomplish the purposes of this Agreement, each Grantor hereby (i) authorizes the Collateral Agent to execute any such agreements, instruments or other documents in such
Grantors name and to file such agreements, instruments or other documents in such Grantors name and in any appropriate filing office, (ii) authorizes the Collateral Agent at any time and from time to time to file, one or more
financing or continuation statements, and amendments thereto, relating to the Collateral (including, without limitation, any such financing statements that (A) subject to the Indenture, describe the Collateral as all assets or
all personal property (or words of similar effect) or that describe or identify the Collateral by type or in any other manner as the Collateral Agent may determine regardless of whether any particular asset of such Grantor falls within
the scope of Article 9 of the Uniform Commercial Code or whether any particular asset of such



-19-



---

Grantor constitutes part of the Collateral, and (B) contain any other information required by Part 5 of Article 9 of the Uniform Commercial Code for the sufficiency or filing office
acceptance of any financing statement, continuation statement or amendment, including, without limitation, whether such Grantor is an organization, the type of organization and any organizational identification number issued to such Grantor) and
(iii) ratifies such authorization to the extent that the Collateral Agent has filed any such financing or continuation statements, or amendments thereto, prior to the date hereof. A photocopy or other reproduction of this Agreement or any
financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement where permitted by law. Each Canadian Grantor acknowledges receipt of a copy of this Security Agreement and copies of the verification
statements pertaining to the financing statements filed under the PPSA by the Collateral Agent in respect of this Security Agreement. To the extent permitted by applicable law, each Grantor irrevocably waives the right to receive a copy of each
financing statement or financing change statement (or any verification statement pertaining thereto) filed under the PPSA or under such other personal property security statutes by the Collateral Agent in respect of this Security Agreement or any
other security agreement, and releases any and all claims or causes of action it may have against any Secured Party for failure to provide any such copy.

(b) Each Grantor hereby irrevocably appoints the Collateral Agent as its attorney-in-fact and proxy, with full authority in the place and stead of such Grantor and in the name of such Grantor or
otherwise, from time to time in the Collateral Agents discretion, so long as an Event of Default shall have occurred and is continuing, to take any action and to execute any instrument necessary or advisable or which the Collateral Agent may
reasonably deem necessary or advisable to accomplish the purposes of this Agreement (subject to the rights of each Grantor under Section 5 hereof), including, without limitation, (i) to obtain and adjust insurance required to be paid to
the Collateral Agent pursuant to Section 5(e) hereof, (ii) to ask, demand, collect, sue for, recover, compound, receive and give acquittance and receipts for moneys due and to become due under or in respect of any Collateral, (iii) to
receive, endorse, and collect any drafts or other instruments, documents and chattel paper in connection with clause (i) or (ii) above, (iv) to file any claims or take any action or institute any proceedings necessary or advisable or
which the Collateral Agent may deem necessary or desirable for the collection of any Collateral or otherwise to enforce the rights of the Secured Parties with respect to any Collateral, and (v) to execute assignments, licenses and other
documents to enforce the rights of the Secured Parties with respect to any Collateral. This power is coupled with an interest and is irrevocable until all of the Obligations are indefeasibly paid in full in cash.

(c) For the purpose of enabling the Collateral Agent to exercise rights and remedies hereunder, at such time as the Collateral Agent
shall be lawfully entitled to exercise such rights and remedies, and for no other purpose, each Grantor hereby grants to the Collateral Agent, to the extent assignable, an irrevocable, non-exclusive license (exercisable without payment of royalty or
other compensation to any Grantor) to use, assign, license or sublicense any Intellectual Property now owned or hereafter acquired by such Grantor, wherever the same may be located, including in such license reasonable access to all media in which
any of the licensed items may be recorded or stored and to all computer programs used for the compilation or printout thereof. Notwithstanding anything contained herein to the contrary, but subject to the provisions of the Indenture that limit the
right of any Grantor to dispose of its property, and Section 5(g) and Section 5(h) hereof, so long as no Event of Default shall have occurred and be



-20-



---

continuing, any Grantor may exploit, use, enjoy, protect, license, sublicense, assign, sell, dispose of or take other actions with respect to the Intellectual Property in the ordinary course of
its business. In furtherance of the foregoing, unless an Event of Default shall have occurred and be continuing, the Collateral Agent shall from time to time, upon the request of any Grantor, execute and deliver any instruments, certificates or
other documents, in the form so requested, which such Grantor shall have certified are appropriate (in such Grantors judgment) to allow it to take any action permitted above (including relinquishment of the license provided pursuant to this
clause (c) as to any Intellectual Property. Further, upon the indefeasible payment in full in cash of all of the Obligations, the Collateral Agent (subject to Section 10(e) hereof) shall cooperate in taking all necessary steps and make all
filings and recordings to release and reassign to any Grantor all of the Collateral Agents right, title and interest in and to the Intellectual Property, and the Licenses, all without recourse, representation or warranty whatsoever. The
exercise of rights and remedies hereunder by the Collateral Agent shall not terminate the rights of the holders of any licenses or sublicenses theretofore granted by each Grantor in accordance with the second sentence of this clause (c). Each
Grantor hereby releases the Collateral Agent from any claims, causes of action and demands at any time arising out of or with respect to any actions taken or omitted to be taken by the Collateral Agent under the powers of attorney granted herein
other than actions taken or omitted to be taken by the Collateral Agents own gross negligence or willful misconduct, as determined by a final determination of a court of competent jurisdiction.

(d) If any Grantor fails to perform any agreement or obligation contained herein, the Collateral Agent may itself perform, or cause
performance of, such agreement or obligation, in the name of such Grantor or the Collateral Agent, and the expenses of the Collateral Agent incurred in connection therewith shall be payable by such Grantor pursuant to Section 8 hereof and shall
be secured by the Collateral.

(e) The powers conferred on the Collateral Agent hereunder are solely to protect its interest
in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Collateral Agent shall have no
duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral.

(f) Anything herein to the contrary notwithstanding (i) each Grantor shall remain liable under the Licenses and otherwise with respect to any of the Collateral to the extent set forth therein to
perform all of its obligations thereunder to the same extent as if this Agreement had not been executed, (ii) the exercise by the Collateral Agent of any of its rights hereunder shall not release any Grantor from any of its obligations under
the Licenses or otherwise in respect of the Collateral, and (iii) the Collateral Agent shall not have any obligation or liability by reason of this Agreement under the Licenses or with respect to any of the other Collateral, nor shall the
Collateral Agent be obligated to perform any of the obligations or duties of any Grantor thereunder or to take any action to collect or enforce any claim for payment assigned hereunder.

(g) Beyond the exercise of reasonable care in the custody thereof, the Collateral Agent shall have no duty as to any Collateral in its
possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior



-21-



---

parties or any other rights pertaining thereto and the Collateral Agent shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in
any public office at any time or times or otherwise perfecting or maintaining the perfection of any security interest in the Collateral. The Collateral Agent shall be deemed to have exercised reasonable care in the custody of the Collateral in its
possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or
omission of any carrier, forwarding agency or other agent or bailee selected by the Collateral Agent in good faith.

(h) The
Collateral Agent shall not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by
reason of any of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence, bad faith or willful misconduct on the part of the Collateral Agent, for the validity or sufficiency of
the Collateral or any agreement or assignment contained therein, for the validity of the title of the Company to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise
as to the maintenance of the Collateral.

SECTION 7. Remedies Upon Event of Default. If any Event of Default shall
have occurred and be continuing:

(a) The Collateral Agent may exercise in respect of the Collateral, in addition to any other
rights and remedies provided for herein or otherwise available to it, all of the rights and remedies of a secured party upon default under the Uniform Commercial Code (whether or not the Uniform Commercial Code applies to the affected Collateral),
and also may (i) take absolute control of the Collateral, including, without limitation, transfer into the Collateral Agents name or into the name of its nominee or nominees (to the extent the Collateral Agent has not theretofore done so)
and thereafter receive, for the benefit of the Collateral Agent, all payments made thereon, give all consents, waivers and ratifications in respect thereof and otherwise act with respect thereto as though it were the outright owner thereof,
(ii) require each Grantor to, and each Grantor hereby agrees that it will at its expense and upon request of the Collateral Agent forthwith, assemble all or part of its respective Collateral as directed by the Collateral Agent and make it
available to the Collateral Agent at a place or places to be designated by the Collateral Agent that is reasonably convenient to both parties, and the Collateral Agent may enter into and occupy any premises owned or leased (if permitted by the
lessor of such premises) by any Grantor where the Collateral or any part thereof is located or assembled for a reasonable period in order to effectuate the Collateral Agents rights and remedies hereunder or under law, without obligation to any
Grantor in respect of such occupation, and (iii) without notice except as specified below and without any obligation to prepare or process the Collateral for sale, (A) sell the Collateral or any part thereof in one or more parcels at
public or private sale, at any of the Collateral Agents offices or elsewhere, for cash, on credit or for future delivery, and at such price or prices and upon such other terms as the Collateral Agent may deem commercially reasonable and/or
(B) lease, license or dispose of the Collateral or any part thereof upon such terms as the Collateral Agent may deem commercially reasonable. Each Grantor agrees that, to the extent notice of sale or any other disposition of its respective
Collateral shall be required by



-22-



---

law, at least ten (10) days notice to any Grantor of the time and place of any public sale or the time after which any private sale or other disposition of its respective Collateral is
to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale or other disposition of any Collateral regardless of notice of sale having been given. The Collateral Agent may adjourn any public or
private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. Each Grantor hereby acknowledges that (i) any such sale
of its respective Collateral by the Collateral Agent or Receiver shall be made without warranty, (ii) the Collateral Agent or Receiver may specifically disclaim any warranties of title, possession, quiet enjoyment or the like, and
(iii) such actions set forth in clauses (i) and (ii) above shall not adversely affect the commercial reasonableness of any such sale of Collateral. In addition to the foregoing, (1) upon written notice to any Grantor from the
Collateral Agent or Receiver after and during the continuance of an Event of Default, such Grantor shall cease any use of the Intellectual Property or any trademark, patent or copyright similar thereto for any purpose described in such notice;
(2) the Collateral Agent or Receiver may, at any time and from time to time after and during the continuance of an Event of Default, upon 10 days prior notice to such Grantor, license, whether general, special or otherwise, and whether on
an exclusive or non-exclusive basis, any of the Intellectual Property, throughout the universe for such term or terms, on such conditions, and in such manner, as the Collateral Agent or Receiver shall in its sole discretion determine; and
(3) the Collateral Agent or Receiver may, at any time, pursuant to the authority granted in Section 6 hereof (such authority being effective upon the occurrence and during the continuance of an Event of Default), execute and deliver on
behalf of such Grantor, one or more instruments of assignment of the Intellectual Property (or any application or registration thereof), in form suitable for filing, recording or registration in any country.

(b) Any cash held by the Collateral Agent or Receiver as Collateral and all Cash Proceeds received by the Collateral Agent or Receiver in
respect of any sale of or collection from, or other realization upon, all or any part of the Collateral shall be applied (after payment of any amounts payable to the Collateral Agent or Receiver pursuant to Section 8 hereof) by the
Collateral Agent or Receiver against, all or any part of the Obligations in such order as the Collateral Agent or Receiver shall elect, consistent with the provisions of the Indenture. Any surplus of such cash or Cash Proceeds held by the Collateral
Agent or Receiver and remaining after the indefeasible payment in full in cash of all of the Obligations shall be paid over to whomsoever shall be lawfully entitled to receive the same or as a court of competent jurisdiction shall direct.

(c) In the event that the proceeds of any such sale, collection or realization are insufficient to pay all amounts to which
the Secured Parties are legally entitled, each Grantor shall be liable for the deficiency, together with interest thereon at the highest rate specified in the Notes for interest on overdue principal thereof or such other rate as shall be fixed by
applicable law, together with the costs of collection and the reasonable fees, costs, expenses and other client charges of any attorneys employed by the Collateral Agent or Receiver to collect such deficiency.

(d) Each Grantor hereby acknowledges that if the Collateral Agent or Receiver complies with any applicable state, provincial, or federal
law requirements in connection with a disposition of the Collateral, such compliance will not adversely affect the commercial reasonableness of any sale or other disposition of the Collateral.



-23-



---

(e) Neither the Collateral Agent nor any Receiver shall be required to marshal any present
or future collateral security (including, but not limited to, this Agreement and the Collateral) for, or other assurances of payment of, the Obligations or any of them or to resort to such collateral security or other assurances of payment in any
particular order, and all of the Collateral Agents or Receivers rights hereunder and in respect of such collateral security and other assurances of payment shall be cumulative and in addition to all other rights, however existing or
arising. To the extent that any Grantor lawfully may, each Grantor hereby agrees that it will not invoke any law relating to the marshaling of collateral which might cause delay in or impede the enforcement of the Collateral Agents or any
Receivers rights under this Agreement or under any other instrument creating or evidencing any of the Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or payment thereof is
otherwise assured, and, to the extent that it lawfully may, each Grantor hereby irrevocably waives the benefits of all such laws.

(f) In addition to its other enforcement rights expressed herein or otherwise at law, the Collateral Agent may appoint by instrument in writing one or more Receivers of any Collateral of any Canadian
Grantor. Any such Receiver shall have the rights set out in paragraph (g) below. In exercising such rights, any Receiver shall act as and for all purposes shall be deemed to be the agent of such Grantor and no Secured Party shall be
responsible for any act or default of any Receiver. The Collateral Agent may remove any Receiver and appoint another from time to time. No Receiver appointed by the Collateral Agent need be appointed by, nor need its appointment be ratified by, or
its actions in any way supervised by, a court. If two or more Receivers are appointed to act concurrently, they shall, unless otherwise expressly provided in the instrument appointing them, so act severally and not jointly and severally. The
appointment of any Receiver or anything done by a Receiver or the removal or termination of any Receiver shall not have the effect of constituting any Secured Party a mortgagee in possession in respect of the Collateral.

(g) Any Receiver appointed by the Collateral Agent shall have such of the following rights, powers, authorities and remedies as the
Collateral Agent shall grant to such Receiver in the instrument appointing such Receiver:

(i) any Receiver may exercise any
rights, powers and remedies to which the Collateral Agent is entitled;

(ii) any Receiver may at any time enter upon any
premises owned, leased or otherwise occupied by any Canadian Grantor or where any Collateral is located to take possession of, disable or remove any Collateral, and may use whatever means the Receiver considers advisable to do so;

(iii) any Receiver shall be entitled to immediate possession of Collateral and the each Canadian Grantor shall forthwith upon
demand by any Receiver deliver up possession to a Receiver of any Collateral;



-24-



---

(iv) any Receiver may carry on, or concur in the carrying on of, any of the business or
undertaking of any Canadian Grantor and may, to the exclusion of all others, including each Canadian Grantor, enter upon, occupy and use any of the premises, buildings, plant and undertaking of or occupied or used by any Canadian
Grantor and may use any of the Equipment and General Intangibles of such Grantor for such time and such purposes as the Receiver sees fit. No Receiver shall be liable to any Grantor for any negligence (other than gross negligence, intentional
misconduct or a violation of any applicable law) in so doing or in respect of any rent, charges, costs, depreciation or damages in connection with any such action; and

(v) any Receiver may have, enjoy and exercise all of the rights of and enjoyed by each Canadian Grantor with respect to the Collateral or incidental, ancillary, attaching or deriving from the
ownership by any Canadian Grantor of the Collateral, including the right to enter into agreements pertaining to Collateral, the right to commence or continue proceedings to preserve or protect Collateral and the right to grant or agree to Liens
and grant or reserve profits à prendre, easements, rights of ways, rights in the nature of easements and licenses over or pertaining to the whole or any part of the Collateral.

(h) The Collateral Agent may, at any time, apply to a court of competent jurisdiction for the appointment of a Receiver, or other
official, who may have powers the same as, greater or lesser than, or otherwise different from, those capable of being granted to a Receiver appointed by the Collateral Agent pursuant to this Security Agreement.

SECTION 8. Indemnity and Expenses.

(a) Each Grantor agrees, jointly and severally, to defend, protect, indemnify and hold the Secured Parties and any Receiver harmless from and against any and all claims, damages, losses, liabilities,
obligations, penalties, fees, costs and expenses (including, without limitation, reasonable legal fees, costs, expenses, and disbursements of such Persons counsel) to the extent that they arise out of or otherwise result from this Agreement
(including, without limitation, enforcement of this Agreement), except to the extent caused by such Persons own gross negligence or willful misconduct, as determined by a final judgment of a court of competent jurisdiction.

(b) Each Grantor agrees, jointly and severally, to pay to the Collateral Agent and Receiver upon demand the amount of any and all costs
and expenses, including the reasonable fees, costs, expenses and disbursements of counsel for the Collateral Agent, Receiver and of any experts and agents (including, without limitation, any collateral trustee which may act as agent of the
Collateral Agent or Receiver), which the Collateral Agent or Receiver may incur in connection with (i) the preparation, negotiation, execution, delivery, recordation, administration, amendment, waiver or other modification or termination of
this Agreement, (ii) the custody, preservation, use or operation of, or the sale of, collection from, or other realization upon, any Collateral, (iii) the exercise or enforcement of any of the rights of the Collateral Agent or Receiver
hereunder, or (iv) the failure by any Grantor to perform or observe any of the provisions hereof.

(c) The benefits of
this Section 8 shall survive the termination of this Agreement.

SECTION 10. Resignation and Removal of the Collateral Trustee

(a) Resignation or Removal of Collateral Agent. Subject to the appointment of a successor Collateral Agent as provided in
Section 10(b) and the acceptance of such appointment by the successor Collateral Agent:

(ii) the Collateral Agent may be removed at any time, with or without cause, by the Holders of a majority in principal amount of the
outstanding Notes.

(b) Appointment of Successor Collateral Agent. Upon any such resignation or removal, a successor
Collateral Trustee may be appointed by the Holders of a majority in principal amount of the outstanding Notes subject to the consent of the Company, which shall not be unreasonably withheld. If no successor Collateral Agent has been so appointed and
accepted such appointment within 45 days after the predecessor Collateral Agent gave notice of resignation or was removed, the retiring Collateral Agent may (at the expense of the Company), at its option, appoint a successor Collateral Agent, or
petition a court of competent jurisdiction for appointment of a successor Collateral Agent, which must be a bank or trust company:

(A) authorized to exercise corporate trust powers;

(B) having a
combined capital and surplus of at least $100,000,000;

provisions of Section 10(c) have been satisfied.

(c) Succession. When the Person so appointed as successor Collateral
Agent accepts such appointment:

(A) such Person will succeed to and become vested with all the rights, powers,
privileges and duties of the predecessor Collateral Agent, and the predecessor Collateral Agent will be discharged from its duties and obligations hereunder; and



-26-



---

promptly transfer all Liens and Collateral within its possession or control to the possession or control of the successor Collateral Agent and will execute instruments and assignments as may be necessary or reasonably requested by the successor

Collateral Agent in respect of the Security Documents.

SECTION 11. Miscellaneous.

(a) No amendment of any provision of this Agreement shall be effective unless it is in writing and signed by each Grantor and the
Collateral Agent, and no waiver of any provision of this Agreement, and no consent to any departure by each Grantor therefrom, shall be effective unless it is in writing and signed by each Grantor and the Collateral Agent, and then such waiver or
consent shall be effective only in the specific instance and for the specific purpose for which given.

(b) No failure on the
part of the Collateral Agent to exercise, and no delay in exercising, any right hereunder or under any of the other Transaction Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any
other or further exercise thereof or the exercise of any other right. The rights and remedies of the Secured Parties provided herein and in the other Transaction Documents are cumulative and are in addition to, and not exclusive of, any rights or
remedies provided by law. The rights of the Secured Parties under any of the other Transaction Documents against any party thereto are not conditional or contingent on any attempt by such Person to exercise any of its rights under any of the other
Transaction Documents against such party or against any other Person, including but not limited to, any Grantor.

(c) Any
provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining portions hereof or thereof or

continuing security interest in the Collateral and shall (i) remain in full force and effect until the indefeasible payment in full in cash of the Obligations, and (ii) be binding on each Grantor and all other Persons who become bound as

permitted successors, transferees and assigns. Without limiting the generality of clause (ii) of the immediately preceding sentence, without notice to any Grantor, the Secured Parties may assign or otherwise transfer their rights and
obligations under this Agreement and any of the other Transaction Documents in accordance



-27-



---

with the respective Transaction Documents, to any other Person and such other Person shall thereupon become vested with all of the benefits in respect thereof granted to the Secured Parties
herein or otherwise. Upon any such assignment or transfer, all references in this Agreement to the Secured Parties shall mean the assignee of the Secured Parties. None of the rights or obligations of any Grantor hereunder may be assigned or
otherwise transferred without the prior written consent of the Collateral Agent, and any such assignment or transfer without the consent of the Collateral Agent shall be null and void.

(e) Upon the indefeasible payment in full in cash of the Obligations, (i) this Agreement and the security interests created hereby
shall terminate and all rights to the Collateral shall revert to the respective Grantor that granted such security interests hereunder, and (ii) the Collateral Agent will, upon any Grantors request and at such Grantors expense,

request to evidence such termination, all without any representation, warranty or recourse whatsoever.

RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH GRANTOR HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY
OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION, SUIT OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS AND CONSENTS TO THE GRANTING OF SUCH LEGAL
OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY THE COURT.

(h) EACH GRANTOR AND (BY ITS ACCEPTANCE OF THE BENEFITS OF THIS AGREEMENT) THE COLLATERAL
AGENT WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED ON, ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER TRANSACTION DOCUMENTS, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, ORAL OR
