Documents, and Investment Property that are in the form of certificated securities, duly executed endorsements or stock powers in blank, as the case may be, affixed thereto in form and substance acceptable to the Administrative Agent and sufficient
under applicable law so that the Administrative Agent, for the benefit of the Secured Parties, shall have a security interest in all such Collateral perfected by possession; provided that such Grantor shall not be required to deliver
Instruments, Documents and Investment Property with an individual value of less than $750,000 or control agreements or bailment agreements with respect to deposit accounts, securities accounts or property held by bailees with an aggregate value of

restrictive legends, and instruments furnished in connection with the creation, enforcement, protection, perfection or priority of the Administrative Agent’s security interest in Collateral, including such items as are described above in this
Section 3, are sometimes referred to herein as “Perfection Documents”. The delivery of possession of items of or evidencing Collateral, causing other Persons to execute and deliver Perfection Documents as appropriate,
the filing or recordation of Perfection Documents, the establishment of control over items of Collateral, and the taking of such other actions as may be necessary or advisable in the determination of the Administrative Agent to create, enforce,
protect, perfect, or establish or maintain the priority of, the security interest of the Administrative Agent for the benefit of the Secured Parties in the Collateral is sometimes referred to herein as “Perfection Action”. 

4. Maintenance of Security Interest; Further Assurances. 

(a) Each Grantor will from time to time at its own expense, deliver specific assignments of Collateral or such other Perfection
Documents, and take such other or additional Perfection Action, as may be required by the terms of the Loan Documents or as the Administrative Agent may reasonably request in connection with the administration or enforcement of this Agreement or
related to the Collateral or any part thereof in order to carry out the terms of this Agreement, to perfect, protect, maintain the priority of or enforce the Administrative Agent’s security interest in the Collateral, subject only to Permitted
Liens, or otherwise to better assure and confirm unto the 

  
 6 

 
Administrative Agent its rights, powers and remedies for the benefit of the Secured Parties hereunder. Without limiting the foregoing, each Grantor hereby irrevocably authorizes the
Administrative Agent to file (with, or to the extent permitted by applicable law, without the signature of the applicable Grantor appearing thereon) financing statements (including amendments thereto and initial financing statements in lieu of
continuation statements) or other Perfection Documents (including copies thereof) showing such Grantor as “debtor” at such time or times and in all filing offices as the Administrative Agent may from time to time determine to be necessary
or advisable to perfect or protect the rights of the Administrative Agent and the Secured Parties hereunder, or otherwise to give effect to the transactions herein contemplated, any of which Perfection Documents, at the Administrative Agent’s
election, may describe the Collateral as or including “all assets” of such Grantor. Each Grantor hereby irrevocably ratifies and acknowledges the Administrative Agent’s authority to have effected filings of Perfection Documents made
by the Administrative Agent prior to its Applicable Date. 
 (b) With respect to any and all Collateral, each Grantor agrees
to do and cause to be done all things necessary to perfect, maintain the priority of and keep in full force the security interest granted in favor of the Administrative Agent for the benefit of the Secured Parties, including, but not limited to, the
prompt payment upon demand therefor by the Administrative Agent of all fees and expenses (including documentary stamp, excise or intangibles taxes) incurred in connection with the preparation, delivery, or filing of any Perfection Document or the
taking of any Perfection Action to perfect, protect or enforce a security interest in Collateral in favor of the Administrative Agent for the benefit of the Secured Parties, subject only to Permitted Liens. All amounts not so paid when due shall
constitute additional Secured Obligations and (in addition to other rights and remedies resulting from such nonpayment) shall bear interest from the date of demand until paid in full at the Default Rate. 

(c) Each Grantor agrees to maintain among its books and records appropriate notations or evidence of, and to make or cause to
be made appropriate disclosure upon its financial statements of, the security interest granted hereunder to the Administrative Agent for the benefit of the Secured Parties. 

5. Receipt of Payment. In the event an Event of Default shall occur and be continuing and a Grantor (or any of its Affiliates,
subsidiaries, stockholders, directors, officers, employees or agents) shall receive any proceeds of Collateral, including without limitation monies, checks, notes, drafts or any other items of payment, each Grantor shall hold all such items of
payment in trust for the Administrative Agent for the benefit of the Secured Parties, and as the property of the Administrative Agent for the benefit of the Secured Parties, separate from the funds and other property of such Grantor, and no later
than the first Business Day following the receipt thereof, at the election of the Administrative Agent, such Grantor shall cause such Collateral to be forwarded to the Administrative Agent for its custody, possession and disposition on behalf of the
Secured Parties in accordance with the terms hereof and of the other Loan Documents. 

  
 7 

 6. Preservation and Protection of Collateral. 

(a) The Administrative Agent shall be under no duty or liability with respect to the collection, protection or preservation of
the Collateral, or otherwise. Each Grantor shall be responsible for the safekeeping of its Collateral, and in no event shall the Administrative Agent have any responsibility for (i) any loss or damage thereto or destruction thereof occurring or
arising in any manner or fashion from any cause, (ii) any diminution in the value thereof, or (iii) any act or default of any carrier, warehouseman, bailee or forwarding agency thereof or other Person in any way dealing with or handling
such Collateral. 
 (b) Each Grantor shall keep and maintain its tangible personal property Collateral as required pursuant
to Section 6.06 of the Credit Agreement. 
 (c) Each Grantor agrees (i) to pay when due all taxes, charges
and assessments against the Collateral in which it has any interest, unless being contested in good faith by appropriate proceedings diligently conducted and against which adequate reserves have been established in accordance with GAAP applied on a
basis consistent with the application of GAAP in the Audited Financial Statements, and (ii) to cause to be terminated and released all Liens (other than Permitted Liens) on the Collateral. Upon the failure of any Grantor to so pay or contest
such taxes, charges, or assessments, or cause such Liens to be terminated, the Administrative Agent at its option may pay or contest any of them or amounts relating thereto (the Administrative Agent having the sole right to determine the legality or
validity and the amount necessary to discharge such taxes, charges, Liens or assessments) but shall not have any obligation to make any such payment or contest. All sums so disbursed by the Administrative Agent, including all documented
out-of-pocket fees and expenses of counsel (collectively, “Attorneys’ Costs”), court costs, reasonable expenses and other charges related thereto, shall be payable on demand by the applicable Grantor to the Administrative Agent
and shall be additional Secured Obligations secured by the Collateral, and any amounts not so paid on demand (in addition to other rights and remedies resulting from such nonpayment) shall bear interest from the date of demand until paid in full at
the Default Rate. 
 7. Status of Grantors and Collateral Generally. Each Grantor represents and warrants to, and covenants
with, the Administrative Agent for the benefit of the Secured Parties, with respect to itself and the Collateral as to which it has or acquires any interest, that: 

(a) It is at its Applicable Date (or as to Collateral acquired after its Applicable Date will be upon the acquisition of the
same) and, except as permitted by the Credit Agreement and subsection (b) of this Section 7, will continue to be, the owner of the Collateral, free and clear of all Liens, other than the security interest hereunder in favor
of the Administrative Agent for the benefit of the Secured Parties and Permitted Liens, and that it will at its own cost and expense defend such Collateral and any products and proceeds thereof against all claims and demands of all Persons (other
than holders of Permitted Liens) to the extent of their claims permitted under the Credit Agreement at any time claiming the same or any interest therein adverse to the Secured Parties. Upon 

  
 8 

 
the failure of any Grantor to so defend, the Administrative Agent may do so at its option but shall not have any obligation to do so. All sums so disbursed by the Administrative Agent, including
reasonable Attorneys’ Costs, court costs, expenses and other charges related thereto, shall be payable on demand by the applicable Grantor to the Administrative Agent and shall be additional Secured Obligations secured by the Collateral, and
any amounts not so paid on demand (in addition to other rights and remedies resulting from such nonpayment) shall bear interest from the date of demand until paid in full at the Default Rate. 

(b) It shall not (i) sell, assign, transfer, lease, license or otherwise dispose of any of, or grant any option with
respect to, the Collateral, except for Dispositions permitted under the Credit Agreement, (ii) create or suffer to exist any Lien upon or with respect to any of the Collateral except for the security interests created by this Agreement and
Permitted Liens, or (iii) take any other action in connection with any of the Collateral that would materially impair the value of the interest or rights of such Grantor in the Collateral taken as a whole or that would materially impair the
interest or rights of the Administrative Agent for the benefit of the Secured Parties. 
 (c) It has full power, legal right
and lawful authority to enter into this Agreement (and any Security Joinder Agreement applicable to it) and to perform its terms, including the grant of the security interests in the Collateral herein provided for. 

(d) No authorization, consent, approval or other action by, and no notice to or filing with, any Governmental Authority or any
other Person which has not been given or obtained, as the case may be, is required either (i) for the grant by such Grantor of the security interests granted hereby or for the execution, delivery or performance of this Agreement (or any
Security Joinder Agreement) by such Grantor, or (ii) for the perfection of or the exercise by the Administrative Agent, on behalf of the Secured Parties, of its rights and remedies hereunder, except for action required by the Uniform Commercial
Code to perfect and exercise remedies with respect to the security interest conferred hereunder. 
 (e) No effective
financing statement or other Perfection Document similar in effect, nor any other Perfection Action, covering all or any part of the Collateral purported to be granted or taken by or on behalf of such Grantor (or by or on behalf of any other Person
and which remains effective as against all or any part of the Collateral) has been filed in any recording office, delivered to another Person for filing (whether upon the occurrence of a contingency or otherwise), or otherwise taken, as the case may
be, except such as pertain to Permitted Liens and such as may have been filed for the benefit of, delivered to, or taken in favor of, the Administrative Agent for the benefit of the Secured Parties in connection with the security interests conferred
hereunder. 
 (f) Schedule 7(f) attached hereto contains true and complete information as to each of the following (in
each case, after giving effect to the Closing Date Transaction): (i) the exact legal name of each Grantor as it appears in its Organization Documents as of its Applicable Date and at any time during the five (5) year period ending as of

by such Grantor, the name and address of the owner thereof and such owner’s relationship to such Grantor (e.g. lessor, warehousemen) as of its Applicable Date. No Grantor shall change its name, change its jurisdiction of formation (whether by
reincorporation, merger or otherwise), change the location of its chief executive office, or utilize any additional location where tangible personal property Collateral (including Account Records and Account Documents) may be located, except in each
case upon giving not less than thirty (30) days’ prior written notice to the Administrative Agent and taking or causing to be taken at such Grantor’s expense all such Perfection Action, including the delivery of such Perfection
Documents, as may be reasonably requested by the Administrative Agent to perfect or protect, or maintain the perfection and priority of, the Lien of the Administrative Agent for the benefit of the Secured Parties in Collateral contemplated hereunder
and except that Mustang Acquisition Inc. may do any of the foregoing on the Closing Date in connection with the Closing Date Acquisition and Mustang Acquisition II LLC (formerly known as Mustang Acquisition II Inc.) may change its name to Met-Pro

Agent, (ii) to the extent requested by the Administrative Agent, such lessor acknowledges the Lien in favor of the Administrative Agent for the benefit of the Secured Parties conferred hereunder and waives its statutory and consensual liens and
rights with respect to such Collateral in form and substance acceptable to the Administrative Agent and delivered in writing to 

  
 10 

 
the Administrative Agent prior to any Collateral being located at any such location, and (iii) such Grantor shall have caused at its expense to be prepared and executed such additional
Perfection Documents and to be taken such other Perfection Action as the Administrative Agent may deem necessary or advisable to carry out the transactions contemplated by this Agreement. 

8. Inspection. The Administrative Agent (by any of its officers, employees and agents), on behalf of the Secured Parties, shall
have the right upon prior notice to an executive officer of any Grantor, and at any reasonable time during such Grantor’s usual business hours, to inspect the Collateral, all records related thereto (and to make extracts or copies from such

otherwise permitted in the Loan Documents) and to verify with any Person other than (except as expressly otherwise permitted in the Loan Documents) Account Debtors the amount, quality, quantity, value and condition of, or any other matter relating

matter relating to, the Collateral with such Account Debtors. 
 9. Specific Collateral. 

(a) Accounts. With respect to its Accounts whether now existing or hereafter created or acquired and wheresoever
located, each Grantor represents, warrants and covenants to the Administrative Agent for the benefit of the Secured Parties that: 

(i) Each Grantor shall keep accurate and complete records of its Accounts (“Account Records”) and from time to
time at intervals designated by the Administrative Agent such Grantor shall provide the Administrative Agent with a schedule of Accounts in form and substance acceptable to the Administrative Agent describing all Accounts created or acquired by such
Grantor (“Schedule of Accounts”); provided, however, that such Grantor’s failure to execute and deliver any such Schedule of Accounts shall not affect or limit the Administrative Agent’s security interest or
other rights in and to any Accounts for the benefit of the Secured Parties. If requested by the Administrative Agent, each Grantor shall furnish the Administrative Agent with copies of proof of delivery and other documents relating to the Accounts
so scheduled, including without limitation repayment histories and present status reports (collectively, “Account Documents”) and such other matter and information relating to the status of then existing Accounts as the
Administrative Agent shall request. 
 (ii) All Account Records and Account Documents are and shall at all times be located
only at such Grantor’s current chief executive office as set forth on Schedule 7(f) attached hereto, such other locations as are specifically identified on Schedule 7(f) attached hereto as an “Account Documents
location,” or as to which such Grantor has complied with Section 7(f) hereof. 

  
 11 

 (iii) The Accounts are genuine, are in all respects what they purport to be, are
not evidenced by an instrument or document or, if evidenced by an instrument or document, are only evidenced by one original instrument or document. 

(iv) The Accounts cover bona fide sales, leases, licenses or other dispositions of property usually dealt in by such Grantor,
or the rendition by such Grantor of services, to an Account Debtor in the ordinary course of business. 
 (v) The amounts of
the face value of any Account shown or reflected on any Schedule of Accounts, invoice statement, or certificate delivered to the Administrative Agent, are actually owing to such Grantor and are not contingent for any reason and there are no setoffs,
discounts, allowances, claims, counterclaims or disputes of any kind or description in an amount greater than $1,000,000 in the aggregate, or greater than $500,000 individually, known to be existing or asserted with respect thereto and such Grantor
has not made any agreement with any Account Debtor thereunder for any deduction therefrom, except as may be stated in the Schedule of Accounts and reflected in the calculation of the face value of each respective invoice related thereto. 

(vi) Except for conditions generally applicable to such Grantor’s industry and markets, there are no facts, events, or
occurrences known to such Grantor pertaining particularly to any Accounts which are reasonably expected to materially impair in any way the validity, collectibility or enforcement of Accounts that would reasonably be likely, in the aggregate, to be
of material economic value, or in the aggregate materially reduce the amount payable thereunder from the amount of the invoice face value shown on any Schedule of Accounts, or on any certificate, contract, invoice or statement delivered to the
Administrative Agent with respect thereto.

(v) Upon the occurrence and during the continuance of any Default or Event of Default, at the option of the Administrative

possession of such Chattel Paper to the Administrative Agent or its designee, and (y) in the event that there shall be created more than one original counterpart of any physical document that alone or in conjunction with any other physical or

electronic Chattel Paper (including the electronic components of hybrid Chattel Paper), no Grantor shall create or acquire any such Chattel Paper unless, prior to such acquisition or creation, it shall have taken such Perfection Action as the
Administrative Agent may require to perfect by control the security interest of the Administrative Agent for the benefit of the Secured Parties in such Collateral. 

(iii) Other than in the ordinary course of business and in keeping with reasonable and customary practice, no Grantor shall
amend, modify, waive or terminate any provision of, or fail to exercise promptly and diligently each material right or remedy conferred under or in connection with, any Chattel Paper, in any case in such a manner as could reasonably be expected to
materially adversely affect the value of affected Chattel Paper as collateral.

to its Instruments whether now existing or hereafter created or acquired and wheresoever located, each Grantor represents, warrants and covenants to the Administrative Agent for the benefit of the Secured Parties that:

Commercial Tort Claims in which any Grantor has an interest and which have been identified by a Grantor as of its Applicable Date, and as to which such Grantor believes in good faith there exists the possibility of recovery (including by way of
settlement) of monetary relief in excess of $500,000 (“Grantor Claims”), in each case after giving effect to the Closing Date Transaction. Each Grantor shall furnish to the Administrative Agent from time to time upon its request a
certificate of an officer of such Grantor referring to this Section 9(i) and (x) identifying all Grantor Claims that are not then described on Schedule 9(i) attached hereto and stating that each of such additional Grantor

settled, or have been made the subject of any binding mediation, judicial or arbitral proceeding, or any judicial or arbitral order on the merits, or that have been abandoned. With respect to each such additional Grantor Claim, such Grantor Claim

applicable Grantor to execute and file such additional financing statements or amendments to previously filed financing statements, and take such other action as it may deem necessary or advisable, to perfect the Lien on such additional Grantor
Claims conferred hereunder, and the applicable Grantor shall, if required by applicable law or otherwise at the request of the Administrative Agent, execute and deliver such Perfection Documents and take such other Perfection Action as the
Administrative Agent may determine to be necessary or advisable to perfect or protect the Lien of the Administrative Agent for the benefit of the Secured Parties in such additional Grantor Claims conferred hereunder.

of the Credit Agreement, which such insurance shall (i) prohibit cancellation or substantial modification, termination or lapse in coverage by the insurer without at least thirty (30) days’ prior written notice to the Administrative
Agent, except for non-payment of premium, as to which such policies shall provide for at least ten (10) days’ prior written notice to the Administrative Agent, and (ii) where applicable, name the Administrative Agent, for the benefit

the name of such Grantor on any check, draft, instrument or other item or payment for the proceeds of such policies of insurance and for making all determinations and decisions with respect to such policies of insurance, which appointment is coupled
with an interest and is irrevocable; provided, however, that the powers pursuant to such appointment shall be exercisable only upon the occurrence and during the continuation of an Event of Default. 

(d) In the event such Grantor shall fail to maintain, or fail to cause to be maintained, the full insurance coverage required

 19 

 
Obligation or Default or Event of Default by such Grantor hereunder, contract for the required policies of insurance and pay the premiums on the same or make any required repairs, renewals and
replacements; and all sums so disbursed by Administrative Agent, including reasonable Attorneys’ Costs, court costs, expenses and other charges related thereto, shall be payable on demand by such Grantor to the Administrative Agent, shall be

(e) The provisions contained in this Agreement pertaining to insurance shall be cumulative with any additional provisions
imposing additional insurance requirements with respect to the Collateral or any other property on which a Lien is conferred under any Collateral Document. 

11. Rights and Remedies Upon Event of Default. Upon and during the continuance of an Event of Default, the Administrative Agent
shall have the following rights and remedies on behalf of the Secured Parties in addition to any rights and remedies set forth elsewhere in this Agreement or the other Loan Documents, all of which may be exercised with or, if allowed by law, without
notice to a Grantor: 
 (a) All of the rights and remedies of a secured party under the UCC or under other applicable law,

or places where any Collateral is located and kept, and remove the Collateral therefrom to the premises of the Administrative Agent or any agent of the Administrative Agent, for such time as the Administrative Agent may desire, in order effectively
to collect or liquidate the Collateral (subject, in the case of any premises that are leased, to any applicable landlord waiver agreements that may be entered into by the Administrative Agent related to such premises), (ii) require such Grantor
or any bailee or other agent of such Grantor to assemble the Collateral and make it available to the Administrative Agent at a place to be designated by the Administrative Agent that is reasonably convenient to both parties, and (iii) notify
any or all Persons party to a control agreement or who otherwise have possession of or control over any Collateral of the occurrence of an Event of Default and other appropriate circumstances, and exercise control over and take possession or custody
of any or all Collateral in the possession, custody or control of such other Persons; 

  
 20 

 (d) The right to (i) exercise all of a Grantor’s rights and remedies
with respect to the collection of Accounts, Chattel Paper, Instruments, Supporting Obligations and General Intangibles (collectively, “Payment Collateral”), including the right to demand payment thereof and enforce payment, by legal
proceedings or otherwise; (ii) settle, adjust, compromise, extend or renew all or any Payment Collateral or any legal proceedings pertaining thereto; (iii) discharge and release all or any Payment Collateral; (iv) take control, in any
manner, of any item of payment or proceeds referred to in Section 5 above; (v) prepare, file and sign a Grantor’s name on any Proof of Claim in bankruptcy, notice of Lien, assignment or satisfaction of Lien or similar document

such Grantor’s post office boxes or make other arrangements as the Administrative Agent, on behalf of the Secured Parties, deems necessary to receive such Grantor’s mail, including notifying the post office authorities to change the
address for delivery of such Grantor’s mail to such address as the Administrative Agent, on behalf of the Secured Parties, may designate; (x) notify any or all Account Debtors or other obligor on any Payment Collateral that such Payment
Collateral has been assigned to the Administrative Agent for the benefit of the Secured Parties and that Administrative Agent has a security interest therein for the benefit of the Secured Parties (provided that the Administrative Agent may at any
time give such notice to an Account Debtor that is a department, agency or authority of the United States government); each Grantor hereby agrees that any such notice, in the Administrative Agent’s sole discretion, may (but need not) be sent on
such Grantor’s stationery, in which event such Grantor shall co-sign such notice with the Administrative Agent if requested to do so by the Administrative Agent; and (xi) do all acts and things and execute all documents necessary, in
Administrative Agent’s sole discretion, to collect the Payment Collateral; and 
 (e) The right to sell all or any
Collateral in its then existing condition, or after any further manufacturing or processing thereof, at such time or times, at public or private sale or sales, with such notice as may be required by law, in lots or in bulk, for cash or on credit,
with or without representations and warranties, all as the Administrative Agent, in its sole discretion, may deem advisable. The Administrative Agent shall have the right to conduct such sales on a Grantor’s premises or elsewhere and shall have
the right to use a Grantor’s premises without charge for such sales for such time or times as the Administrative Agent may see fit. The Administrative Agent may, if it deems it reasonable, postpone or adjourn any sale of the Collateral from
time to time by an announcement at the time and place of such postponed or adjourned sale, and such sale may, without further notice, be made at the time and place to which it was so adjourned. Each Grantor agrees that the Administrative Agent has
no obligation to preserve rights to the Collateral against prior parties or to marshal any Collateral for the 

  
 21 

 
benefit of any Person. The Administrative Agent for the benefit of the Secured Parties is hereby granted an irrevocable fully paid license or other right (including each Grantor’s rights
under any license or any franchise agreement), each of which shall remain in full force and effect until the Facility Termination Date, to use, without charge, each of the labels, patents, copyrights, names, trade secrets, trade names, trademarks
and advertising matter, or any property of a similar nature owned or licensed by any Grantor, as it pertains to the Collateral, in completing production of, advertising for sale and selling any Collateral. If any of the Collateral shall require
repairs, maintenance, preparation or the like, or is in process or other unfinished state, the Administrative Agent shall have the right, but shall not be obligated, to perform such repairs, maintenance, preparation, processing or completion of
manufacturing for the purpose of putting the same in such saleable form as the Administrative Agent shall deem appropriate, but the Administrative Agent shall have the right to sell or dispose of the Collateral without such processing and no Grantor
shall have any claim against the Administrative Agent for the value that may have been added to such Collateral with such processing. In addition, each Grantor agrees that in the event notice is necessary under applicable law, written notice mailed
to such Grantor in the manner specified herein ten (10) days prior to the date of public sale of any of the Collateral or prior to the date after which any private sale or other disposition of the Collateral will be made shall constitute
commercially reasonable notice to such Grantor. All notice is hereby waived with respect to any of the Collateral which threatens to decline speedily in value or is of a type customarily sold on a recognized market. The Administrative Agent may
purchase all or any part of the Collateral at public or, if permitted by law, private sale, free from any right of redemption which is hereby expressly waived by such Grantor and, in lieu of actual payment of such purchase price, may set off the
amount of such price against the Secured Obligations. 
 The net cash proceeds resulting from the collection, liquidation, sale, or other
disposition of the Collateral shall be applied first to the expenses (including all Attorneys’ Costs) of retaking, holding, storing, processing and preparing for sale, selling, collecting, liquidating and the like, and then to the satisfaction
of all Secured Obligations in accordance with the terms of Section 8.03 of the Credit Agreement. Each Grantor shall be liable to the Administrative Agent, for the benefit of the Secured Parties, and shall pay to the Administrative Agent,
for the benefit of the Secured Parties, on demand any deficiency which may remain after such sale, disposition, collection or liquidation of the Collateral. 

12. Attorney-in-Fact. Each Grantor hereby appoints the Administrative Agent as such Grantor’s attorney-in-fact for the
purposes of carrying out the provisions of this Agreement and taking any action and executing any instrument which the Administrative Agent may deem necessary or advisable to accomplish the purposes hereof, which appointment is irrevocable and
coupled with an interest; provided that the Administrative Agent shall have and may exercise rights under this power of attorney only upon the occurrence and during the continuance of an Event of Default. Without limiting the generality of
the foregoing, upon the occurrence and during the continuance of an Event of Default, the Administrative Agent shall have the right and power 

  
 22 

 (a) to ask, demand, collect, sue for, recover, compromise, receive and give
acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral; 
 (b) to receive,
endorse and collect any drafts or other instruments, documents and chattel paper in connection with
 clause (a) above; 

(c) to endorse such Grantor’s name on any checks, notes, drafts or any other payment relating to or constituting proceeds
of the Collateral which comes into the Administrative Agent’s possession or the Administrative Agent’s control, and deposit the same to the account of the Administrative Agent, for the benefit of the Secured Parties, on account and for
payment of the Secured Obligations. 
 (d) to file any claims or take any action or institute any proceedings that the
Administrative Agent may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of the Administrative Agent, for the benefit of the Secured Parties, with respect to any of the Collateral; and 

(e) to execute, in connection with any sale or other disposition of Collateral provided for herein, any endorsement,
assignments, or other instruments of conveyance or transfer with respect thereto. 
 13. Reinstatement. The granting of a
security interest in the Collateral and the other provisions hereof shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Secured Obligations is rescinded or must otherwise be returned by any
Secured Party or is repaid by any Secured Party in whole or in part in good faith settlement of a pending or threatened avoidance claim, whether upon the insolvency, bankruptcy or reorganization of any Grantor or any other Loan Party or otherwise,
all as though such payment had not been made. The provisions of this Section 13 shall survive repayment of all of the Obligations and the termination or expiration of this Agreement in any manner, including but not limited to termination
upon occurrence of the Facility Termination Date. 
 14. Certain Waivers by the Grantors. Each Grantor waives to the extent
permitted by applicable law (a) any right to require any Secured Party or any other obligee of the Secured Obligations to (i) proceed against any Person or entity, including without limitation any Loan Party, (ii) proceed against or
exhaust any Collateral or other collateral for the Secured Obligations, or (iii) pursue any other remedy in its power; (b) any defense arising by reason of any disability or other defense of any other Person, or by reason of the cessation
from any cause whatsoever of the liability of any other Person or entity, (c) any right of subrogation, and (d) any right to enforce any remedy which any Secured Party or any other obligee of the Secured Obligations now has or may
hereafter have against any other Person and any benefit of and any right to participate in any collateral or security whatsoever now or hereafter held by the Administrative Agent for the benefit of the Secured Parties. Each Grantor authorizes each
Secured Party and each other obligee of the Secured Obligations without notice (except notice required by applicable law) or demand and without affecting its liability hereunder or under the Loan Documents from time to time to: (i) take and
hold security, other than the Collateral herein 

  
 23 

 
described, for the payment of such Secured Obligations or any part thereof, and exchange, enforce, waive and release the Collateral herein described or any part thereof or any such other
security; and (ii) apply such Collateral or other security and direct the order or manner of sale thereof as such Secured Party or obligee in its discretion may determine. 

The Administrative Agent may at any time deliver (without representation, recourse or warranty) the Collateral or any part thereof to a
Grantor and the receipt thereof by such Grantor shall be a complete and full acquittance for the Collateral so delivered, and the Administrative Agent shall thereafter be discharged from any liability or responsibility therefor. 

15. Continued Powers. Until the Facility Termination Date shall have occurred, the power of sale and other rights, powers and
remedies granted to the Administrative Agent for the benefit of the Secured Parties hereunder shall continue to exist and may be exercised by the Administrative Agent at any time and from time to time irrespective of the fact that any of the Secured
Obligations or any part thereof may have become barred by any statute of limitations or that any part of the liability of any Grantor may have ceased. 

16. Other Rights. The rights, powers and remedies given to the Administrative Agent for the benefit of the Secured Parties by
this Agreement shall be in addition to all rights, powers and remedies given to the Administrative Agent or any Secured Party under any other Loan Document or by virtue of any statute or rule of law. Any forbearance or failure or delay by the
Administrative Agent in exercising any right, power or remedy hereunder shall not be deemed to be a waiver of such right, power or remedy, and any single or partial exercise of any right, power or remedy hereunder shall not preclude the further
exercise thereof; and every right, power and remedy of the Secured Parties shall continue in full force and effect until such right, power or remedy is specifically waived in accordance with the terms of the Credit Agreement. 

17. Anti-Marshaling Provisions. The right is hereby given by each Grantor to the Administrative Agent, for the benefit of the
Secured Parties, to make releases (whether in whole or in part) of all or any part of the Collateral agreeable to the Administrative Agent without notice to, or the consent, approval or agreement of other parties and interests, including junior
lienors, which releases shall not impair in any manner the validity of or priority of the Liens and security interests in the remaining Collateral conferred hereunder, nor release any Grantor from personal liability for the Secured Obligations.
Notwithstanding the existence of any other security interest in the Collateral held by the Administrative Agent, for the benefit of the Secured Parties, the Administrative Agent shall have the right to determine the order in which any or all of the
Collateral shall be subjected to the remedies provided in this Agreement. Each Grantor hereby waives any and all right to require the marshaling of assets in connection with the exercise of any of the remedies permitted by applicable law or provided
herein or in any other Loan Document. 
 18. Entire Agreement. This Agreement and each Security Joinder Agreement, together
with the Credit Agreement and other Loan Documents, constitute and express the entire understanding between the parties hereto with respect to the subject matter hereof, and supersede all prior negotiations, agreements and understandings,
inducements, commitments or conditions, express or implied, oral or written, except as contained in the Loan Documents. The express 

  
 24 

 
terms hereof and of the Security Joinder Agreements control and supersede any course of performance or usage of the trade inconsistent with any of the terms hereof or thereof. Neither this
Agreement nor any Security Joinder Agreement nor any portion or provision hereof or thereof may be changed, altered, modified, supplemented, discharged, canceled, terminated, or amended orally or in any manner other than as provided in the Credit
Agreement. 
 19. Third Party Reliance. Each Grantor hereby consents and agrees that all issuers of or obligors in respect of
any Collateral, and all securities intermediaries, warehousemen, bailees, public officials and other Persons having any interest in, possession of, control over or right, privilege, duty or discretion in respect of, any Collateral shall be entitled
to accept the provisions hereof and of the Security Joinder Agreements as conclusive evidence of the right of the Administrative Agent, on behalf of the Secured Parties, to exercise its rights hereunder or thereunder with respect to the Collateral,
notwithstanding any other notice or direction to the contrary heretofore or hereafter given by any Grantor or any other Person to any of such Persons. 

20. Binding Agreement; Assignment. This Agreement and each Security Joinder Agreement, and the terms, covenants and conditions
hereof and thereof, shall be binding upon and inure to the benefit of the parties hereto, and to their respective successors and assigns, except that no Grantor shall be permitted to assign this Agreement, any Security Joinder Agreement or any
interest herein or therein or, except as expressly permitted herein or in the Credit Agreement, in the Collateral or any part thereof or interest therein. Without limiting the generality of the foregoing sentence of this Section 20, any
Lender may assign to one or more Persons, or grant to one or more Persons participations in or to, all or any part of its rights and obligations under the Credit Agreement (to the extent permitted by the Credit Agreement); and to the extent of any
such assignment or participation such other Person shall, to the fullest extent permitted by law, thereupon become vested with all the benefits in respect thereof granted to such Lender herein or otherwise, subject however, to the provisions of the
Credit Agreement, including Article IX thereof (concerning the Administrative Agent) and Section 10.06 thereof (concerning assignments and participations). All references herein to the Administrative Agent and to the Secured
Parties shall include any successor thereof or permitted assignee, and any other obligees from time to time of the Secured Obligations. 

21. Secured Cash Management Agreements and Secured Hedging Agreements. No Secured Party (other than the Administrative Agent)
that obtains the benefit of this Agreement shall have any right to notice of any action or to consent to, direct or object to any action hereunder or otherwise in respect of the Collateral (including the release or impairment of any Collateral)
other than in its capacity as a Lender or an L/C Issuer and, in such case, only to the extent expressly provided in the Loan Documents. Notwithstanding any other provision of this Agreement to the contrary, the Administrative Agent shall only be
required to verify the payment of, or that other satisfactory arrangement have been made with respect to, the Secured Obligations arising under Secured Cash Management Agreements and Secured Hedge Agreements to the extent the Administrative Agent
has received written notice of such Obligations, together with such supporting documentation as it may request, from the applicable Cash Management Bank or Hedge Bank, as the case may be. Each Secured Party not a party to the Credit Agreement that
obtains the benefit of this Agreement shall be deemed to have acknowledged and accepted the appointment of the Administrative Agent pursuant to the terms 

  
 25 

 
of the Credit Agreement, and that with respect to the actions and omissions of the Administrative Agent hereunder or otherwise relating hereto that do or may affect such Secured Party, the
Administrative Agent and each of its Related Parties shall be entitled to all the rights, benefits and immunities conferred under Article IX of the Credit Agreement. 

22. Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable, (a) the legality,
validity and enforceability of the remaining provisions of this Agreement shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such
provision in any other jurisdiction. 
 23. Counterparts. This Agreement may be executed in any number of counterparts each of
which when so executed and delivered shall be deemed an original, and it shall not be necessary in making proof of this Agreement to produce or account for more than one such counterpart executed by the Grantor against whom enforcement is sought.
Without limiting the foregoing provisions of this Section 23, the provisions of Section 10.10 of the Credit Agreement shall be applicable to this Agreement. 

24. Termination. Subject to the provisions of Section 13, this Agreement and each Security Joinder Agreement, and all
obligations of the Grantors hereunder (excluding those obligations and liabilities that expressly survive such termination) shall terminate without delivery of any instrument or performance of any act by any party on the Facility Termination Date.
Upon such termination of this Agreement, the Administrative Agent shall, at the request and sole expense of the Grantors, promptly deliver to the Grantors such termination statements and take such further actions as the Grantors may reasonably
request to terminate of record, or otherwise to give appropriate notice of the termination of, any Lien conferred hereunder. 
 25.
Notices. Any notice required or permitted hereunder shall be given (a) with respect to any Grantor, at the address then in effect for the giving of notices to the Company under the Credit Agreement and (b) with respect to the
Administrative Agent or a Lender, at the Administrative Agent’s address indicated in Schedule 10.02 of the Credit Agreement. All such addresses may be modified, and all such notices shall be given and shall be effective, as provided in
Section 10.02 of the Credit Agreement for the giving and effectiveness of notices and modifications of addresses thereunder. 

26. Joinder. Each Person that shall at any time execute and deliver to the Administrative Agent a Security Joinder Agreement
substantially in the form attached hereto as Exhibit A shall thereupon irrevocably, absolutely and unconditionally become a party hereto and obligated hereunder as a Grantor and shall have thereupon pursuant to Section 2 granted a
security interest in and collaterally assigned to the Administrative Agent for the benefit of the Secured Parties all Collateral in which it has at its Applicable Date or thereafter acquires any interest or the power to transfer, and all references
herein and in the other Loan Documents to the Grantors or to the parties to this Agreement shall be deemed to include such Person as a Grantor hereunder. Each Security Joinder Agreement shall be accompanied by the Supplemental Schedules referred to
therein, appropriately completed with information relating to the Grantor executing such Security Joinder Agreement and its property. Each of the applicable Schedules attached hereto shall be deemed amended and supplemented without further action by
such information reflected on the Supplemental Schedules. 

  
 26 

 27. Rules of Interpretation. The rules of interpretation contained in
Section 1.02 of the Credit Agreement shall be applicable to this Agreement and each Security Joinder Agreement and are hereby incorporated by reference. All representations and warranties contained herein shall survive the delivery of
documents and any Credit Extensions referred to herein or secured hereby.

 B. The Company, certain of its
Subsidiaries and the Administrative Agent are party to a Security Agreement dated as of August 27, 2013 (as in effect on the date hereof, the “Security Agreement”).

In order to induce the Secured Parties to from time to time make and maintain extensions of credit under the Credit Agreement, Secured Cash
Management Agreements and Secured Hedge Agreements, the Joining Grantor hereby agrees as follows: 
 1. Joinder. The Joining
Grantor hereby irrevocably, absolutely and unconditionally becomes a party to the Security Agreement as a Grantor and bound by all the terms, conditions, obligations, liabilities and undertakings of each Grantor or to which each Grantor is subject
thereunder, including without limitation the grant pursuant to Section 2 of the Security Agreement of a security interest to the Administrative Agent for the benefit of the Secured Parties in the property and property rights constituting

Work as substantially completed. 
 6.         Landlord Estoppel. As additional
